Blake McAnally	5c91e0d6fe	feat(relay): add kind 30180 custom emoji entry (#8783) ... ## Summary This PR adds kind 30180, `KIND_EMOJI_ENTRY`. One event holds one custom emoji. The relay accepts, validates, stores, and replaces these events. The SDK gets `build_emoji_entry`. `docs/nips/NIP-CE.md` documents the kind. This is the relay part of the custom-emoji scale-up (Option C). It does not change kind 30030 sets, message `emoji` tags, or reaction `emoji` tags. It adds no migration and no schema change. **Read this before you deploy.** Prefix search for kind 30180 works only on a database whose `events.search_tsv` indexes that kind. See "Search index" below. ## Design - `crates/buzz-core/src/kind.rs`: `KIND_EMOJI_ENTRY = 30180`. It is in `ALL_KINDS`. A compile-time check proves it is parameterized replaceable. 30180 was free on `origin/main`. - `crates/buzz-relay/src/handlers/ingest.rs`: - The kind needs `UsersWrite`. - The kind is global-only. It is never channel-scoped. - `validate_emoji_entry` runs before storage. It requires exactly one `d` tag and exactly one `emoji` tag. - It rejects any `h` tag. - It requires `d` to equal the shortcode in the `emoji` tag, and both to equal the normalized shortcode. - It requires an `http://` or `https://` URL of at most 2048 bytes. It uses the SDK check `check_custom_emoji_url`, which is now public. - It caps `content` at 256 bytes (`MAX_EMOJI_ENTRY_CONTENT_LEN`). A shortcode is at most 64 bytes, so the cap leaves room. - Every rejection starts with `invalid:`. - `crates/buzz-sdk/src/builders.rs`: `build_emoji_entry(shortcode, url)` and `emoji_entry_search_text`. The content is the shortcode with `_` and `-` replaced by spaces. - Replace semantics use the existing parameterized-replaceable path. A second publish with the same `(pubkey, d)` leaves one live event. Two authors with the same `d` keep two events. The NIP tells clients to prefer the newest event and report the conflict. ### Decisions - **WebSocket `search_mode`: not changed.** Prefix search works through `POST /query`, which already reads `search_mode`. This is the smallest correct change. The `REQ` search path still uses full-word matching. The NIP says so. A client that needs typeahead uses `POST /query`. - **Search text.** Postgres `simple` already splits `party_parrot` at the underscore. It keeps `sad-parrot` as one token and also indexes `sad` and `parrot`. So the space replacement is not needed for matching today. It is kept because it is harmless and does not depend on parser details. - **Content cap of 256 bytes.** The cap is documented in the NIP and the code doc comment. ### Search index (important) The design doc says kind 30030 is not excluded from the full-text index. That is true for `schema/` (the desired state): it indexes every kind except a deny list. It is not true for a database that was created by `migrations/`: - Migration 0008 gives a fresh install a positive allowlist: kinds 0, 9, 40002, 45001, 45003. - `scripts/maintenance/nip_rs_search_allowlist.sql` moves a populated database to the same allowlist. On an allowlist database, kind 30180 is **stored and resolvable by `#d`, but not searchable**. I did not change this. A change to `search_tsv` rewrites the partitioned `events` table. That needs the reviewed out-of-band procedure in `docs/database.md` (rules 6 and 5), and this task forbids migrations and schema files. Before clients depend on search, a human must check the deployed expression: ```sql SELECT pg_get_expr(adbin, adrelid) FROM pg_attrdef d JOIN pg_attribute a ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attname = 'search_tsv' AND d.adrelid = 'events'::regclass; ``` If the result lists `kind IN (0, 9, ...)`, add 30180 to the allowlist through the out-of-band procedure first. ## Spike I ran this on a throwaway local Postgres 17 (Docker), desired-state schema from `pgschema`. The loader inserted 100,000 kind 30180 events from 200 authors through `Db::replace_parameterized_event`. It used 16 parallel tasks, and it did not use the network. The loader was a scratch example. It is not in this PR. Rows landed in `events_p_future` because the local partitions end at 2026-06. Real deployments have monthly partitions, so scans split across partitions. **Insert rate.** 100,000 inserts took 33.9 s (about 2,900 per second) at the DB layer. The relay adds rate limits on top (see the design doc, section 2.5). **`#d` batch of 50 names** (actual relay SQL shape, warm cache, `LIMIT 100`): | Case | Plan | Execution time | |------|------|----------------| | No `authors` | Index scan on `idx_events_parameterized`. It uses `community_id` and `kind` only. `d_tag` is not a leading key, so it scans the kind range. | 12 ms warm, 28 ms cold | | 50 names, all their authors (50 distinct) | Index scan with `pubkey` and `d_tag` in the index condition | 1.5 ms | | 50 names, one author | Same index, tight condition | 0.13 ms | Result: with `authors`, the lookup is fast. Without `authors`, the cost grows with the number of entries of the kind. At 100,000 rows it is still tens of milliseconds. No index change is needed now. Re-measure at 1,000,000 rows. **Prefix search**, `kinds=[30180]`, relevance order (the default), `LIMIT 50`: | Query | Matching rows | Execution time (warm) | |-------|---------------|-----------------------| | `parr` | 8,169 | 115 ms (124 ms cold) | | `p` | 15,990 | 219 ms | | `party par` | 8,169 | 266 ms (cold) | | `zap blob 999` (rare) | 1 | 0.4 ms | | `parr` with `search_sort: "newest"` | 8,169 | 0.8 ms | Result: the GIN index finds matches fast. Relevance order then scores every matching row (`ts_rank_cd`) and sorts them. The cost grows with the number of matches, not with `limit`. My synthetic words are few (24), so each prefix matches many rows. Real names are more varied, but a one- or two-letter query will still match many rows. The `search_sort: "newest"` option avoids the scoring and was 150 times faster here. Clients should use `search_sort: "newest"` for typeahead, or require at least 3 characters. This is a recommendation for the client work. It needs no relay change. **Side effects of bulk insert** (from reading `ingest.rs` and `handlers/event.rs`): - Audit log: each accepted event queues one `EventCreated` audit entry. The audit worker writes them one at a time under an advisory lock. The queue holds 1000 entries and uses `send().await`, so a bulk run slows the writer down instead of dropping entries. 96,000 events add 96,000 audit rows. - Live fan-out: each event is published to the global topic and matched against open subscriptions in `sub_registry`. A client with an open filter for kind 30180 receives every event. - Workflow triggers: each event spawns a task that calls `workflow_engine.on_event`. That is one trigger lookup per event. - Push: the DB push enqueue only matches kinds 9, 40002, 45001, and 45003 (`PUSH_MATCH_KINDS`). Kind 30180 does not wake push subscribers. - No `channel_id`, so the `events_created_at_floor_guard` trigger does not apply. ## Testing What ran (all on the final tree): - `cargo test -p buzz-core -p buzz-sdk -p buzz-relay -p buzz-search`: pass. - `cargo clippy -p buzz-core -p buzz-sdk -p buzz-relay -p buzz-search --all-targets -- -D warnings`: pass. - `cargo fmt --all --check`: pass. - `just file-size-check`: pass. - Postgres lane, desired-state schema (`BUZZ_TEST_SCHEMA_MODE=desired`) with a local Redis: `cargo test -p buzz-relay --lib handlers::ingest -- --include-ignored`: 205 passed, including the four new tests. New tests: - `emoji_entry_validation_table` (no infra): one row for each rule. - `emoji_entry_is_a_global_users_write_kind` (no infra). - `emoji_entry_ingest_validates_and_replaces` (Postgres): goes through `ingest_event`. It rejects a bad shortcode, `d` not equal to shortcode, an `h` tag, and a non-http URL. It checks that nothing is stored. It then publishes twice with the same `d` and checks that one live event remains and that it is the newer one. - `emoji_entry_prefix_search_finds_by_word_prefix` (Postgres): `parr` finds `party parrot` and `sad parrot`. `party par` finds one. `joy` finds `bufo joy`. It fails with a clear message on an allowlist database. - SDK: `emoji_entry_happy_path` and `emoji_entry_rejects_bad_input`. Not run: - `just test` was not run in full. I ran the relevant Postgres tests directly. - `cargo test -p buzz-search --test postgres_fts_integration` fails 23 of 23 on my shared local database. Those fixtures use fixed hostnames and need the fresh-database lane (`scripts/postgres-test-run.sh`). I did not change that crate. This is an environment limit, not a result of this change. - The new search test fails on a database built by `buzz-admin migrate` (allowlist). That is the finding above. It passes on the desired-state schema that the CI lane uses (`postgres-test-run.sh`). - I ran no live relay and no end-to-end client. Interop evidence: none for this item. The desktop and mobile constants are out of scope here. `/home/bloxer/ref/interop.mjs` was not needed because no TypeScript changed. Mutation checks (break the guard, confirm a test fails, restore): | Mutation | Result | |----------|--------| | Remove the `validate_emoji_entry` call | `emoji_entry_ingest_validates_and_replaces` fails | | Remove the `h` tag check | table test and ingest test fail | | Remove the `d == shortcode` check | table test and ingest test fail | | Remove the URL check | table test and ingest test fail | | Remove the content cap | table test fails | | Allow more than one `d` tag | table test fails | | Allow more than one `emoji` tag | table test fails | | Remove the kind from `required_scope_for_kind` | scope test, ingest test, and search test fail | | Remove the kind from `is_global_only_kind` | global test and ingest test fail | | SDK: skip shortcode normalization | both SDK tests fail | | SDK: skip the URL check | `emoji_entry_rejects_bad_input` fails | | SDK: skip the space replacement | `emoji_entry_happy_path` fails | One guard has no relay-level test: the space replacement does not change search results, because Postgres already splits `_`. The SDK test covers it. ## Manual test steps You need Docker and a local checkout. Use a local relay only. 1. Start the services and apply the desired-state schema, so that search indexes kind 30180: ```bash cd ~/buzz && . ./bin/activate-hermit docker run -d --name buzz-pg -e POSTGRES_USER=buzz -e POSTGRES_PASSWORD=buzz_dev -e POSTGRES_DB=buzz -p 127.0.0.1:5432:5432 postgres:17-alpine redis-server --daemonize yes --save "" PGHOST=localhost PGPORT=5432 PGUSER=buzz PGPASSWORD=buzz_dev PGDATABASE=buzz ./bin/pgschema apply --file schema/schema.sql --auto-approve docker exec -i buzz-pg psql -U buzz -d buzz -v ON_ERROR_STOP=1 < scripts/reconcile-schema-after-pgschema.sql ``` Success: `Changes applied successfully!`. 2. Run the new tests: ```bash export BUZZ_TEST_DATABASE_URL=postgres://buzz:buzz_dev@localhost:5432/buzz BUZZ_TEST_SCHEMA_MODE=desired cargo test -p buzz-relay --lib emoji_entry -- --include-ignored cargo test -p buzz-sdk --lib emoji_entry ``` Success: 4 relay tests and 2 SDK tests pass. 3. Optional, with a local relay (`just relay`) and a local key. Send these through `POST /events` with the SDK or a small script that calls `build_emoji_entry("party_parrot", "https://example.com/p.gif")`. Success: the relay returns `accepted: true`. - Publish a second entry with the same shortcode. Query `POST /query` with `{"kinds":[30180],"#d":["party_parrot"]}`. Success: one event, the newer one. - Query `{"kinds":[30180],"search":"parr","search_mode":"prefix","limit":50}`. Success: the entry is in the result. - Publish an entry that has an `h` tag or an `ftp://` URL. Success: the relay returns `invalid:`. 4. Check your target database before you rely on search (the SQL in "Search index"). Success: the expression does not list an allowlist such as `kind IN (0, 9, 40002, 45001, 45003)`. If it does, search does not find kind 30180 yet. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: bmcanally <bmcanally@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 17:28:05 -06:00
Luke Tornquist	47be2e2d3f	fix(db): keep busy-reader history reads off the writer and cap them per pod (#9132) ... ## Problem A routed read that misses the reader's 150ms acquire budget (`reader_acquire_timeout`) falls back to the writer, whatever the read is. Under a burst of subscription-history reads (REQ history, channel and thread windows, feeds, search hydration, COUNT), the reader pool fills, and every miss moves a heavy history query onto the writer. There it competes with the authentication, tenant-resolution and moderation lookups that only the writer serves, and their latency climbs with it. Nothing bounds how many history reads a pod sends to the reader at once, so the reader queue grows without limit as well. Separately, the compatibility families `buzz_db_pool_acquire_wait_seconds` and `buzz_db_pool_acquisitions_total` have no `operation` label, so a breakdown by operation reports every sample as unlabelled. ## Changes 1. **History reads no longer spill onto the writer when the reader is busy** (`Db::route_read`). `route_read` now returns `Result<RouteDecision>`. For `ReaderOperation::SubscriptionHistory`, a `reader_acquire_timeout` on a saturated reader pool rejects the read with `sqlx::Error::PoolTimedOut`. Saturated means every connection the pool may hold exists and none is idle (`Db::reader_saturated`). The check is needed because sqlx also reports a reader that refuses dials as `PoolTimedOut`, and that reader is down, not busy. The relay already answers that with its generic retryable `CLOSED` `error: database error`, so there is no new client contract. A reader that is wrong rather than busy (unreachable, validation failure, proof timeout, stale token) and prechecks that never reach the reader still fall back to the writer. Authorization reads (`is_relay_member`) keep the writer fallback unchanged. 2. **Per-pod cap on reader-served history reads** (`runtime/history_reads.rs`). A FIFO `tokio::sync::Semaphore` admits at most the reader pool size less one fifth (at least one) history reads at once. For example, the default pool of 20 admits 16. The remaining connections are normally free for authorization reads. A read waits at most 1s for a permit and is otherwise rejected the same way. The permit is owned by the reader transaction (`ReaderTx`) and released when the transaction is dropped; routed reads drop it before re-running a failed replica read on the writer. That holds whether the transaction is a per-call routed read or a `ReadSession` the relay keeps for follow-up queries. The cap bounds history transactions, not connections: sqlx returns a dropped transaction's connection asynchronously through the reader release check. Released connections can therefore briefly occupy the free slots, for one round trip normally and at most the 5s release timeout when sockets stall. In that window, authorization reads fall back to the writer as before, and history reads on the saturated pool are rejected, not spilled. 3. **Rejections are observable**: `buzz_db_route_decision{decision="rejected",reason="history_read_cap"|"reader_acquire_timeout"}`. 4. **Legacy pool families gain `operation`.** The population is unchanged, and summing over `operation` gives the original series. 5. **HTTP reads answer 503 `database unavailable` when the database can't be reached** (`api::db_read_error`). This covers a pool timeout, closed pool or socket failure on `POST /query`, `/count` and every bridge `/query` branch that serves a history read (channel window, the three feeds, thread replies), including a shed history read. These used to return a generic 500. The thread-window path already answered 503 for pool timeouts; this applies the same mapping to the shared helper. Pool sizes are unchanged on purpose. A larger pool adds lock contention on the writer rather than relieving it. Docs: `deploy/charts/buzz/README.md` (operator contract) and `PLANS/REPLICA_FULL_READ_ROUTING_DESIGN.md` (fail-closed exceptions). ## What got simpler The concept count is roughly flat. Instead of a caller-side permit, the permit lives in the one type every replica transaction already flows through (`RouteDecision::Replica` / `ReadSessionInner::Replica`). The 11 routed call sites change only by a `?`, and the compiler enforces that change: a call site cannot silently fall through to the writer on a rejection. No new error variant, CLOSED reason or env var. ## Tests - `postgres_tests::saturated_reader_spends_one_acquire_budget_and_rejects_history_reads` (rewrites the former `routed_fallback_spends_one_acquire_budget_when_aurora_cache_is_cold`). A size-1 reader is held saturated with a cold Aurora cache. A history read (`count_events_routed`) is rejected with `PoolTimedOut` within one acquire budget, records `rejected/reader_acquire_timeout`, and releases its permit. An authorization read on the same reader still falls back as `writer/reader_acquire_timeout`. - `postgres_tests::match_nothing_reads_take_no_connection` (unchanged): its control still requires a history read against an unreachable reader to fall back to the writer. It caught the first cut of this change, which rejected that read. - `postgres_tests::history_permit_follows_the_read_session_and_a_full_gate_rejects`: a held replica `ReadSession` keeps its permit. With the gate full, the next history read waits the full permit budget and is then rejected as `rejected/history_read_cap`, with no writer route recorded. Dropping the session frees the permit and the next read routes to the replica. - `history_reads::tests`: a cap sizing table, plus bounded-wait rejection and reopen under paused time. - `observability` label tests now require `operation` on both legacy families. - `api::db_read_error_tests::unavailable_database_maps_to_retryable_503`: pool timeout, closed pool and I/O map to 503 `database unavailable`. Other errors stay 500. - `postgres_tests::shed_history_read_maps_to_503_on_every_bridge_branch`: with the reader saturated, `/query` channel-window, mentions, needs_action, activity and thread-reply requests each answer 503 `database unavailable` (each serves 200 beforehand). - Mutation-checked on Blox: re-enabling the writer spill, forcing the saturation check either way, skipping the gate, dropping the permit early and removing the legacy label each fail a test. ## Residual - During a reader failover whose old sockets stall, both slots sit in the release check, so the pool reads as saturated. History reads are shed as retryable for up to the release bound (5s) instead of loading the writer. `stalled_reader_sessions_release_their_slots_for_new_connections` now retries through that window and still requires recovery onto the reader. - A reader that accepts no TCP at all can fill the pool with in-flight dials and look saturated. Its history reads are then rejected rather than moved to the writer, which is the same outcome as a full gate. - Shedding relies on clients backing off on a retryable `CLOSED` (RPR #9). WebSocket clients already treat `error: database error` as retryable. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 22:12:30 +00:00
Luke Tornquist	9b4b73eb08	fix(relay): bound mesh dials and keep failing pods out of the mesh (#8752) ... ## Problem A rolling deploy can stall relay startup for 30s per dead mesh peer. - A pod publishes its mesh ready record during `mesh_boot` and clears it only on graceful shutdown. If a later fatal startup check kills the pod, the record lingers until it expires. - Dialing that address never gets an answer, so `MeshEndpoint::connect` waits out QUIC's default 30s idle timeout. `reconcile_once` dials candidates one at a time, so every dead peer adds another 30s, both in the boot-time `mesh_initial_reconcile` step and in every later reconcile pass. - The fatal check that killed those pods was the git conformance probe. A transient S3 `500 InternalError` on one racer was treated as a conformance failure. ## Changes 1. **Bounded, concurrent mesh dials** (`buzz-relay-mesh/src/runtime.rs`). Each connect attempt is wrapped in `DIAL_TIMEOUT` (2s; in-cluster handshakes take milliseconds), and a reconcile pass dials its candidates concurrently. A pass with dead peers now costs about one dial timeout instead of 30s per peer. The candidate set is bounded by the membership table. 2. **Conformance probe before mesh boot** (`buzz-relay/src/main.rs`). This only moves an existing block, so a pod that fails the probe exits before it publishes a ready record peers would dial. 3. **5xx racers are unknown outcomes** (`buzz-relay/src/api/git/store.rs`). The race phases already drop socket/send failures from the observer set as "outcome unknown". A 5xx is the backend declining to classify the write, so it now joins them through one shared `racer_outcome_unknown` helper. 4xx answers, including 412, still count as evidence. A backend that 5xxs every racer still fails closed on the two-observer floor. Because a dropped racer's write may still have landed, every `if_match_race` round now reads the pointer back and requires the winner's exact body and ETag. Otherwise a backend that commits a stale write and then answers 5xx would pass in the last round. §Conformance steps 2–3 in `docs/git-on-object-storage.md` now state this drop-and-floor rule. ## What got simpler The two duplicated drop-classification match arms in the probe now share one helper. The probe/mesh fix is a reorder of existing startup steps, not a new mechanism or rollback path. ## Tests - `runtime::tests::reconcile_pass_bounds_dials_to_unresponsive_peers`: three black-hole peers (bound UDP sockets that never read) plus one live peer. The pass must finish within `2 × DIAL_TIMEOUT` (a serial pass would take at least `3 × DIAL_TIMEOUT`, and without the timeout about 30s), the live peer must connect, and each dead peer must end `Disconnected`. - `store::tests::probe_drops_5xx_racers_but_keeps_4xx_as_evidence`: pins the classification boundary (5xx and I/O are unknown; 400/403/412/499 are evidence). - `store::fault_probe::*`: runs `run_conformance_probe` against an in-process S3 fake that injects racer faults at the HTTP boundary, so responses pass through rust-s3's `fail-on-err` mapping and retry. One 5xx racer in either race phase is dropped and admitted (`transport_drops == 1`). Too few classified observers fail closed: one observer in either phase, and all-5xx in `if_none_match_race`. An unexpected 4xx racer fails closed in both phases. A racer whose stale write lands and is then answered 5xx fails closed on the post-round readback (`dropped_racer_whose_stale_write_lands_fails_closed`). A clean fake passes with zero drops. - CI lane: no `api::store` test ran in any CI lane before, including the existing ones. The `just test-unit` nextest filter and the `scripts/run-tests.sh` fallback now select `api::store::tests` and `::fault_probe`. The live-MinIO `::probe` module stays opt-in. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 15:56:07 -05:00
Luke Tornquist	50c10dc7b2	perf(relay): cache the community-active check on socket admission (#9109) ... ## What Socket admission (root and audio) and the ephemeral write fence now share one cache of "is this community active?". An entry is served for 1 s after its read checked out a pool connection, and concurrent misses for one community share one read. Archive and deletion drop the entry before they close the community's sockets. ## Why Every new socket runs `is_community_active` before it can authenticate. In a reconnect storm that means thousands of identical reads for one community. A read that times out in the pool refuses the socket (`community active check failed; refusing the socket`), and the client then reconnects and adds more load. On a local cold-start reconnect rig, this refusal count roughly tripled once #9012 freed pool capacity for other reads. It is now one of the top causes of connect failures. ## How - `buzz_db::Db::is_community_active_read_at` returns the answer together with the instant its connection was checked out, following the #9012 `ReadAt` pattern. `is_community_active` now calls it, and the datastore span stays under its existing name. - `community_active::CommunityActiveCache` holds an entry per community and a `SharedReads` gate. An entry is served for `COMMUNITY_ACTIVE_MAX_AGE` (1 s) after its read. Both answers are cached. A cached "inactive" fails safe and lasts at most 1 s after an unarchive. Errors are not cached. - **The archive sweep stays exact.** Admission registers a socket before it checks, so the sweep closes every socket registered before it. A socket that registers after the sweep must see the community as inactive. `apply_community_disconnect` invalidates the entry before the fence and sweep. Invalidation bumps an epoch, and a fill whose read began before the bump is not published. A post-sweep socket therefore reads afresh. It cannot take a pre-archive answer from the cache or from a shared in-flight read. Host invalidations (archive and unarchive writes, local and received) also drop the entry. - **Bound when the notification is missed.** A pod that misses the Redis disconnect admits sockets from a cached "active" for at most 1 s after the archive commits. Lifecycle revalidation then closes them. This matches the 1 s host-routing bound in `docs/community-auth-upgrades.md` ("archive and deletion … cached tenant binding can lag those changes by up to one second"). Deletion keeps its own write fence (`guard_community_write`). - Lifecycle revalidation and persistent ingest still read uncached. ## What got simpler The ephemeral fence's separate `serving_active_cache` is gone. It ran the same SQL predicate through `is_serving_active`, used a 10 s TTL and had no invalidation. The connect path, the WebSocket ephemeral path and HTTP typing now share one cache with one 1 s bound and one invalidation path. That leaves one fewer cache concept, and the ephemeral fence goes from 10 s stale to at most 1 s. ## Tests - `community_active::tests` (unit): - 16 concurrent misses cost one read, and an entry past its max age is re-read. - An invalidation during an in-flight read fences that fill. A waiter that joined the read reads afresh and gets "inactive". - Errors are not cached. - `connection::tests::bootstrap_admits_from_the_cached_community_answer`: with the database unreachable, a cached "active" admits a socket through the real `handle_connection`, and the socket gets its AUTH challenge. - `postgres_tests::cache_misses_behind_a_held_pool_share_one_fresh_read` now also covers this cache. With a one-connection pool held past every max age, eight concurrent admission checks cost one DB read, and the entry lands fresh. - `postgres_tests::archived_community_is_refused_after_invalidation_or_max_age`: after an applied archive, the next check refuses at once. An archive this pod never hears about refuses once the entry passes 1 s. - The ephemeral and typing fence tests now seed the new cache. - Mutation-checked on Blox. Each of these turns a test red: dropping the epoch fence, the max-age filter, the single-flight gate, the connect path's cached read, or the disconnect invalidation; stamping `read_at` before the pool wait; and calling the uncached read on the ephemeral path. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 14:09:14 -05:00
Logan Johnson	700e690193	feat(db): enforce unique listed channel names with an index (#8787) ... ## Summary Stacked on https://github.com/block/buzz/pull/8782 (merged), which makes the relay refuse a second open channel with a name that another channel in the community already has. That check lives in relay code, so an older relay, a direct database write or a missed code path can still create a duplicate. This PR adds the same rule to the database: a unique index on channel name, ignoring case, for the channels that show in the channel list. With the index in place, a duplicate fails at the write, whatever wrote it. The relay's own name check from https://github.com/block/buzz/pull/8782 is no longer needed, so this PR removes it. Clients still get the same refusal, `invalid: an open channel named "…" already exists`. The migration builds the index itself, also on a populated `channels` table, so an auto-migrating relay upgrades with no operator index step (the rule from https://github.com/block/buzz/pull/8802). It still refuses to run while duplicate names remain, because the index cannot exist over them. `docs/channel-name-uniqueness-deployment.md` gives the full rollout. ## Details - **The index** (migration `0083_channels_listed_name_unique.sql`): ```sql CREATE UNIQUE INDEX idx_channels_listed_name ON public.channels (community_id, lower(name)) WHERE visibility = 'open' AND NOT unlisted AND channel_type IN ('stream', 'forum') AND deleted_at IS NULL; ``` It covers open, not unlisted streams and forums that are not deleted, archived ones included. Private channels, DMs and unlisted channels may still repeat names. - **The migration builds the index inline, as `0049` does.** When `to_regclass` finds no index, it runs a plain `CREATE UNIQUE INDEX` under `lock_timeout` 1s and `statement_timeout` 5s. On a busy or very large table it fails on those budgets, records nothing, and the relay retries at its next start. When the index already exists (a concurrent prebuild), it skips `CREATE` so it never requests the write-blocking lock. In both cases it then checks that the index is valid, ready and has the exact expected definition. - **One refusal stays: duplicate names.** The migration refuses to run while listed duplicates remain, and its error names the rename script. The renames must go through the relay so clients get the new kind:39000, and a migration must not change rows (`docs/database.md` Rule 3). This is the "fails closed until its repair has run" case in `migrations/AGENTS.md`, so the writer release from https://github.com/block/buzz/pull/8782 and the rename are a required stop. - **Relay.** A write that takes the name of a concurrent, uncommitted write waits for it, and fails if that write commits. So the post-write check and the per-name lock from https://github.com/block/buzz/pull/8782 are removed. The store already maps the index violation to the same "name taken" error. - **Desired-state schema.** `schema/tables/public/channels.sql` has the same index, and the schema parity test compares its live shape between the desired-state schema and the migrations. - **Rollout** (`docs/channel-name-uniqueness-deployment.md`), in order: 1. Deploy https://github.com/block/buzz/pull/8782 and wait until no older relay pod serves. 2. Rename the existing duplicates in each community with that PR's script, while relays keep serving. The script needs `psql` and `python3`, and the operator key must be a member of each community. The doc covers archived communities and communities being deleted. 3. Confirm that no duplicate remains. 4. Only for a deployment that migrates out of band and is too large for the budgets: build the index with `CREATE UNIQUE INDEX CONCURRENTLY` and verify it. 5. Deploy this release. With auto-migration on, the relay applies 0083 at startup. With it off, run `buzz-admin migrate` first, never the file through `psql`. Rollback goes to the https://github.com/block/buzz/pull/8782 release only. Keep the index, and keep auto-migration off. - **Test fixtures.** Tests that inserted two open channels with one name now use distinct names. Tests that migrate a populated database through 0083 no longer prebuild the index. ### Related issue None found. Follows https://github.com/block/buzz/pull/8782. ### Testing - Migration tests (`listed_channel_name_postgres_tests.rs`) start from a database migrated through 0082: - With duplicates, 0083 fails and changes nothing. - After the rename plan is applied, a channel writer that holds its lock makes the inline build fail on the 1s lock budget, with nothing recorded. - With no writer, the populated table migrates with no prebuild, and a raw duplicate insert fails on the index. - An index with a different definition, and an invalid one, are refused. A valid prebuilt index is accepted, and not replaced, while another transaction is writing to `channels`. - The store and relay name tests from https://github.com/block/buzz/pull/8782 pass with the relay check removed: the index refuses the duplicate, and the client still gets `invalid:`. - The rename plan and script tests from https://github.com/block/buzz/pull/8782 run on a database at 0082, the state the script runs in. - Local Postgres runs on `108737dc0`, one fresh database per test as the nextest wrapper does: 38 of 40 buzz-db migration-lane tests pass (both listed-name tests, the migration parity test, the thread-window and invite-upgrade tests that migrate populated databases through 0083). The 2 `event_follow_up` contract tests fail locally the same way on main. All 49 buzz-db channel and channel-member store tests pass. ### Database review checklist - [x] Phase: contract. Before it: https://github.com/block/buzz/pull/8782 (writer release, required stop) and its rename script. Nothing after it. - [x] No trigger, function, procedure, rule or foreign key. - [x] No migration mutates rows. The renames happen before it, through the relay, with the script in https://github.com/block/buzz/pull/8782. - [x] Never refuses a table because it has rows. Fails closed only with duplicates (repair not run) or with an invalid or different index; then 0083 raises and the relay does not start. The release notes must name the release that contains https://github.com/block/buzz/pull/8782 as a required stop. - [x] Rule 4: `migrations/`, `schema/tables/public/channels.sql` and the parity test. A live catalog comparison covers the index. - [x] Deployed relay: the https://github.com/block/buzz/pull/8782 relay answers `invalid:` beside the index (its tests pass with the index present). A relay older than that still writes, but gets a database error, not `invalid:`, for a duplicate. That is why https://github.com/block/buzz/pull/8782 is a required stop. - [x] Timeouts and index build: `lock_timeout` 1s, `statement_timeout` 5s. The migration builds the index inline (plain `CREATE UNIQUE INDEX`, skipped when `to_regclass` finds a prebuilt one). Only out-of-band deployments too large for the budgets prebuild it with `CREATE UNIQUE INDEX CONCURRENTLY` (doc step 4). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 22:47:23 -05:00
Brad Seiler	64d12e2975	BUZZ-511: Honor relay mode for community NIP-FI enforcement (#8988) ... ## Summary Apply relay mode consistently across protected HTTP, root/audio WebSocket, Git, media and V1 admission. Off requires no NIP-FI, including for stored required communities. Shadow enforces only stored community requirements and observes other communities. Enforce requires NIP-FI for every community. Durable requirements survive all mode changes. Off retains ordinary tenant routing and authentication. It skips FI policy/dependency reads for admission, uses cached WebSocket tenant routing, and loads no FI binding snapshot at startup. Discovery reports `requires_nip_fi=false` and no FI capability in Off. Evaluating modes retain same-row WebSocket binding and immutable HTTP policy tenants, including host remaps, pending deletion and unarchive races. Global Enforce discovery retains its existing compatibility behavior. Host-specific root NIP-11 and `/info` expose the additive `requires_nip_fi` field with no-store. In evaluating modes, an unavailable policy returns 503 and an unknown or non-serving host returns 404. Off uses ordinary routing; a discovery lookup failure returns 404. Stored requirements in Shadow require usable FI dependencies. Admission does not establish activation. BUZZ-512 owns existing-session application, drain and mode-aware readback; its separate revision must report stored requirements as suspended in Off. Production baseline verification and human acceptance remain open. Community status now shares the bounded host cache: 10,000 entries, one-second leases measured before checkout, coalesced fills, and no cached misses or errors. Git reuses one request policy. Root/audio retain the final primary binding check: two reads on a cold successful upgrade, one on a cache hit. Off creates no verifier or JWKS source and reads no FI policy. Proof metrics count stored-required Shadow enforcement. Acceptance locks and validates the community row, takes the matching host advisory lock, and drains optional leases for 1.1 seconds before commit. Reads begun after commit see required across participating relay instances, even without Redis invalidation. The row lock closes single and double remap races. Admissions already in flight remain subject to BUZZ-512 activation fencing. ### Related issue [BUZZ-511](https://linear.app/squareup/issue/BUZZ-511/relay-enforce-per-community-nip-fi-policy-and-publish-compatible). [BUZZ-510 / #8985](https://github.com/block/buzz/pull/8985) is merged; this PR now targets main. The restack retains main’s #8974 denial telemetry and artifact capabilities. Related work includes #8526 tenant lookup errors and #8444 media authorization. ### Rollout and containment Keep `BUZZ_NIP_FI_UPGRADES_ENABLED=false`. [The rollout plan](docs/community-auth-upgrades.md#staging-and-containment) starts in staging with zero required rows and a 30-minute before/after traffic comparison. Initial abort limits include any policy timeout/503, policy-read p99 above 50 ms, writer acquisition p99 above 20 ms or twice baseline, and a five-minute 503 increase above 0.1 percentage point. These are initial limits to validate against measured staging results, not production capacity claims. Verify signed/unsigned free controls, real required root/audio upgrades, dependency failures, restart behavior and discovery before expansion. Also watch binding timeouts/errors and their current generic 404 responses on known serving hosts alongside writer-pool pressure; evaluating root/audio binding has a 500 ms budget; Off uses ordinary cached routing. In Shadow, a pre-511 rollback loses enforcement of accepted community requirements. Stop new upgrade calls, retain accepted policy and receipts, and repair with an enforcing binary or operator-approved containment. Never clear durable policy to restore access. Off deliberately suspends FI enforcement and must be an explicit operator mode choice. No production activation is claimed. All acceptance paths must implement the lease protocol before upgrades are enabled. Keep upgrades disabled through a mixed-version rollout. For rollback, disable new acceptance before removing the protocol while caching pods remain. A cold policy fill uses a six-statement transaction and a 400 ms server timeout within the 500 ms lookup budget. A contended policy fill returns 503. During the drain, archive, deletion, ownership, issuer-binding and competing acceptance writers for that community may wait; ordinary serving reads and writes retain their existing behavior. Host-binding changes retain the existing one-second routing bound. Local and Redis invalidation accelerate refresh; safety does not depend on delivery. Deploy the verified Shadow revocation behavior from #8991 before accepting required communities in Shadow. ### Testing Published review-fix head: `39dfe79b1fc04f10ee3eb94d6ea42cf686bafe1e`, tree `1e2e8d3abd39ee1d6821defe8c8d34de73726e08`. McKeon cleared this cache delta. Full affected auth (291), DB (192), pubsub (31) and relay (1,682) package tests passed, including integration binaries. Two previously documented hardcoded-Redis audit tests remained excluded. All-target clippy, all 1,297 native PostgreSQL tests and the full pubsub Redis suite passed. The full ACP package and `just ci` passed after rebuilding cached test executables that embedded a removed checkout path. No ACP source changed. Tauri's generated lockfile delta was archived and restored; it is excluded from this candidate. Both positive lease regressions passed. Four deliberately broken variants failed at the intended assertions: removing the drain left an optional lease alive after 202.935667 ms; skipping the fill lock failed contention refusal; moving the timestamp after the read failed the anchor check; taking the host lock before the row failed the remap-blocking check. Exact source was restored after each mutation. These are local validation results, not a deployed-fleet acceptance claim. All applicable normal push hooks passed. GitHub reports the exact tested head and tree; the published code has no delta from the reviewed candidate. Earlier mode-correction evidence follows for context. Current mode-correction head: `aa9abf07284b56a88eb78a2014e590f39d705288`, on main `af54258f19ac32667c027f889652bdeb479c8e13`. Its code equals reviewed `f1e7da5fc5`, plus the independently reviewed operator documentation follow-up; all 19 earlier remote patches are preserved. McKeon verified the correction and its mapping to the tested candidate. The mode-correction candidate passed full auth (291) and relay (1,679) package tests, clippy, and four explicit native PostgreSQL policy workflows. There were 623 ignored relay tests and two excluded Redis tests. Real PostgreSQL checks cover an ordinary unsigned caller on a stored-required host in Off with no FI token or dependencies, discovery false, durable policy retained, root/audio upgrades, host remaps and the unarchive race in evaluating modes. The `STORED_OFF` mutation fails the enum truth table only; `OFF_PRIMARY` fails cached upgrade routing. Restored source hashes match. Earlier failed compile/fixture attempts remain recorded. The first normal push hook attempt passed Tauri checks but failed the gateway startup verifier test (82/83 gateway tests passed). The remote remained unchanged. The retry rebuilt gateway artifacts with separate root and Tauri caches, then passed every normal push hook and published this head. No gateway source changes or hook bypasses were needed. Current-head hosted CI is tracked separately. Human acceptance and the staging binding-timeout/404 workflow remain open. The following retained validation and controls are historical and describe behavior before the mode correction; their Off-enforcement statements are superseded by the Summary above. Published head: `9a717fa89725f9430ff4a8bb78cd600affb8836d`, on main `1055f79d048ef22c878d02a7afb04f49c753564f`. CI, three schema checks, 2,136 ordinary tests, all 291 auth tests, 12 Redis tests, all 1,300 native PostgreSQL tests and discovery passed. The required wrapper passed units, then exited 1 at unavailable Docker bootstrap. BUZZ-510 is complete at `95c8d31c835d6f7ff6e432fb1ed248771d4f06dd`: CI, three schema checks, 2,127 ordinary tests, 12 Redis tests, all 1,295 native Postgres tests and discovery passed; its wrapper passed units and failed at unavailable Docker bootstrap. The first native run at historical BUZZ-510 `5380cb72` passed 1,291 tests and failed two event-follow-up queue assertions and the scale-sync case. All three passed serially, then the full 1,294-test run passed with normal concurrency. The original cause remains unresolved; failed runs and resource samples are retained. Standalone BUZZ-511 checks exposed access-slot callers, a Clippy warning and early HTTP 503 attribution that had remained in the child. All are now corrected in the parent. The unchanged real-router refusal regression passed before the latest commit. BUZZ-512's final tree is unchanged by moving these parent prerequisites. The remaining 46-file child delta was audited; no additional parent prerequisite was found. Earlier compile and native failures remain archived. The following earlier-head results and controls are historical; the current-head validation is reported above. At `48388834f99b8d045e243b619904cb3e27b47146`, based on BUZZ-510 `130f14a675edd7cbe6a69d1c9d7818bd1a51f46c` and reconciled main `152441ae0a56b204b42b6faa56a36ad2b98218b1`: - `just ci`: passed. - Four-package ordinary suite: 2,069 passed; full `buzz-auth` package: 291 passed. - Native Redis: 12 passed. Native PostgreSQL: 1,261 passed. PostgreSQL discovery checks passed. - Required `just test`: units passed, then exited 1 because Docker service bootstrap was unavailable. Native service results above are separate. - Real-router remap checks reject an A-only member under B policy, avoid A data after B admission, and advertise B in discovery despite a stale A cache. Removing each tenant pin separately fails its intended witness; restored source passes. An unmapped host cannot reuse a cached tenant. - Deadline witnesses advance their clock during real HTTP signature verification and retain socket primary-lookup barriers. Removing either final enforced or shadow HTTP deadline check separately fails its intended witness; restored source passes both deadlines and the single-resolution control. - Telemetry regression: unsigned dev proofs now expect the earlier NIP-98 `missing` denial; signed mismatched-key proofs retain pairing denial and signer attribution. Removing unsigned-proof rejection fails the exact two-counter assertion. Restored full relay package: 1,654 passed. - Preserved failed runs: two prior bottom-layer desktop gates failed an immediate inventory assertion, repaired with a bounded wait for the same observable arrays and verified with delayed-notification and frozen-provider controls. An earlier BUZZ-511 native run passed 1,242 tests and failed two deadline fixtures that relied on the tenant lookup removed by the policy pin; the test-only adaptation above replaces that seam. These failures remain archived. The first native run on bottom-layer `130f14a6` passed 1,255 tests and failed partition contention; its focused original test and fresh full 1,256-test run passed without source changes. The cause remains unresolved. The first CI run at `d8d88433` failed the old telemetry expectation; the test-only correction above preserves exact denial counts and attribution. Earlier evidence at `dddf05d8be8195d567db0f989f70825b1246a6c1` (historical head): - `cargo nextest run -p buzz-auth -p buzz-db -p buzz-relay --lib --tests`: 2,139/2,139 passed. - `scripts/postgres-test-run.sh -p buzz-db -p buzz-relay --lib --tests --success-output final`: 1,236/1,236 passed with native PostgreSQL 16 and Redis. Docker's legacy `just test` wrapper was unavailable. - `just ci`: passed, including repository checks, tests and client builds. - **Pre-correction behavior (superseded):** Real ES256 assertions through TCP root/audio upgrades: valid evidence upgrades; missing evidence denies in Off/Shadow, including submitted/inventoried/approved deletion stages. Restoring the old query makes the regression fail on an assertion-less Off/submitted/root HTTP 101. - **Pre-correction behavior (superseded):** Deterministic unarchive race: Notify barriers pause an actual archived-host policy miss; the same required row becomes serving before binding. Both root/audio deny missing assertions and admit valid ES256 assertions in Off/Shadow. Ignoring bound-row policy makes this test fail on an assertion-less HTTP 101. - The full rerun exposed an existing cancellation fixture whose synthetic five-second replica fence expired between probes. Refreshing that test fence per operation preserves its timeout assertions; the full suite now passes. - Local probe: 100 serial uncached primary policy reads took 12.33 ms. Production latency is unmeasured. No packaged-app, human or deployed-fleet acceptance run. Live activation awaits BUZZ-512 and the staging verification tickets. Published with the three-layer stack in one atomic push through normal hooks. The published stack includes main `1055f79d048ef22c878d02a7afb04f49c753564f`, including access logging, storage reporting and mobile read-state changes. Access-slot integration and early HTTP refusal attribution belong to BUZZ-511; activation callback refusal close owners belong to BUZZ-512. Every changed layer requires review at its published head and new-head CI. Fresh trunk, remote membership, queue and immutable-lease guards passed before publication. All nine normal pre-push hook lanes passed; no hooks were bypassed. Remote heads, chained bases, membership, ready/draft states and native tracking were verified after publication. Trunk’s merged 0081 is unchanged. The parent upgrade expansion is 0082 and activation is 0083, with contiguous migrator versions, updated documentation and a populated-upgrade fixture starting at 81. Trunk’s storage-test repair supersedes our earlier local repair. Before publication, main advanced three commits from `1055f79d048ef22c878d02a7afb04f49c753564f` to `ba7d7825ea` (desktop deep-link settling and mobile pairing/sign-in). The normal branch-skew guard passed. Those later trunk commits are outside this validated published head; current-trunk CI and delta review remain required before merge.

Tom Brow	e558f15faa	Mobile: one New chat screen (#9079) ... Mobile had two New chat screens. [#8884](https://github.com/block/buzz/pull/8884) made the Flutter draft page (first send creates and names the chat) the New chat screen, but kept the older create form (a native iOS sheet, with a Flutter bottom sheet on Android) for one case: resuming a creation that an older build had saved with a chat name and no first message. Nothing creates that state anymore, so the old form only appeared for users with an interrupted creation from before that change. This removes the old form. Every New chat, including that resume case, now opens the draft page: - **New chat**: unchanged. - **Resuming an interrupted creation**: after the existing Resume / Discard setup / Later prompt, the draft page shows the saved chat with its agent and workspace locked and a Retry button, the same choices the old sheet offered when it locked its fields. A creation saved with a first message resumes exactly as before. One saved without a message finishes without one, because a saved creation can't change after its first relay write. The iOS editor's chat-only code (`presentChat`, `updateChatAssistants`, the agent list, and its avatar loader) goes too. The same editor still handles profile fields, channel details and workspace names. The native test and CI step that covered only the removed chat form are removed. ### Screenshots Resuming an interrupted creation saved without a first message: | Before: old native sheet (removed) | After: draft page (kept) | | --- | --- | | <img src="https://raw.githubusercontent.com/block/buzz/5d0a502e92fc3dfeffbe4fa95d63ba8f73d1e612/pr-9079--01-before-resume-native-sheet.png" width="300"> | <img src="https://raw.githubusercontent.com/block/buzz/5d0a502e92fc3dfeffbe4fa95d63ba8f73d1e612/pr-9079--02-after-resume-draft-page.png" width="300"> | A brand new chat already opened the draft page and is unchanged: <img src="https://raw.githubusercontent.com/block/buzz/5d0a502e92fc3dfeffbe4fa95d63ba8f73d1e612/pr-9079--03-new-chat-draft-page.png" width="300"> ### Validation - Changed tests: `me_page_test` checks that Resume and Discard setup both open the draft page and that no native sheet is requested. `solo_creation_tags_test` checks that recovering an interrupted named creation through the draft page's Retry continues with member setup, keeps the saved name and agent, and adds no first message. - Full mobile Flutter suite (4,431 passed) and `flutter analyze` (clean). iOS debug simulator build succeeds. - Automated simulator run (iPhone 17 Pro, iOS 27, signed-in account): New chat opened the draft page, the agent picker selected an agent, and the first send created the chat, which then appeared under Solo. New workspace still opened the native editor, enabled Create once named, and showed the Discard changes prompt on cancel. The recording isn't attached here because it shows internal account content. - Resuming an interrupted pre-[#8884](https://github.com/block/buzz/pull/8884) creation can't be produced by the current build. For the screenshots above, a capture-only, uncommitted patch to a `main` build seeded one; the branch build installed over it resumed it on the draft page. The widget tests cover finishing it. - `solo_creation_tags_test` also covers a conflicting pending Solo organization edit during that Retry: the draft offers the Conflicting Solo changes dialog, keeps the saved creation, and the next Retry finishes it. 🤖 Generated with [Claude Code](https://claude.com/claude-code) buzz-review-completed --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 16:34:05 -08:00
Luke Tornquist	d21f0c0fdb	perf(relay): keep 1 s read caches warm when the pool is saturated (#9012) ... ## What The relay's 1-second read caches (restriction state, tenant host, open channels) now date each entry from when the read checked out its pool connection, not from when the cache miss began. Concurrent misses on the restriction and tenant-host caches now share one database read. The open-channels cache already did this. ## Why Each of these caches serves an entry for 1 s after "the read that produced it began". Today that start time is taken before waiting for a pool connection. Once pool waits reach about a second (for example, many clients reconnecting at once), every entry is already expired by the time it lands. The cache hit rate falls toward zero exactly when the pool is saturated, so every request does its own read. Those reads queue for the same connections, which stretches the waits further. Requests that time out in the pool then fail closed (`internal error checking restriction state`, `community active check failed; refusing the socket`), and their clients reconnect and add more load. In a local synthetic reconnect load test with a 50-connection pool: - the restriction cache served fewer than one request in five from cache; - the tenant-host cache, which has a single key for the whole deployment, missed more often than it hit; - the open-channels cache missed hundreds of thousands of times on expired entries. ## How - **Stamp at checkout.** `buzz_db::ReadAt<T>` carries a value plus the instant its connection was checked out. The statement's snapshot is no older than that instant, so serving the value for 1 s after it keeps the documented staleness bound, however long the read queued. Three `*_read_at` methods return it: `moderation_restriction_state_read_at`, `lookup_community_by_host_read_at` and `get_listed_open_channel_ids_read_at`. The existing methods now call these and drop the value's timestamp. Each operation keeps one datastore span under its existing name, carried by the `*_read_at` method. - **Share concurrent misses.** `SharedReads<K>` is the per-key gate the open-channels cache already used, moved into its own module. The open-channels cache, the restriction cache and the tenant-host cache now all use it. The first miss reads; the others wait for it, then recheck the cache. A waiter waits for at most the writer pool's acquire timeout plus `SHARED_READ_STATEMENT_WAIT` (1 s). That covers the leader's own wait for a connection, which is what grows in a storm, so waiters keep sharing its read instead of queueing duplicate reads behind it. A failed or cancelled leader releases its waiters at once. A leader whose statement hangs stalls them for at most 1 s past the acquire timeout, never the statement timeout. - **Reject hosts no community can have.** `bind_community` rejects a host longer than `communities.host VARCHAR(255)` can hold (`buzz_core::tenant::MAX_HOST_LEN`, counted in characters) as unmapped, next to the empty-host check. An unauthenticated caller's arbitrarily long host therefore never reaches a resolver, cache, gate or the database. No staleness bound changes: every entry is still served for at most 1 s after its read's snapshot. Invalidation paths are unchanged. A read in flight at an invalidation can still refill the old row for at most that bound, as documented today. ## What got simpler The open-channels gate's hand-rolled `try_lock`/`timeout` block is replaced by `SharedReads::turn`. One gate implementation now serves three caches instead of one implementation that only one cache had. The gate's wait is set once per gate rather than passed at each call site. Provisioning and host binding share one `MAX_HOST_LEN` instead of a private constant. ## Tests - `shared_reads::tests`: one caller reads while the rest wait; a waiter gives up on a hung read after its bound. - `concurrent_restriction_and_host_misses_share_the_in_flight_read`: waiters on both caches use the leader's entry; with an unreachable database, any waiter that read on its own would fail. - `postgres_tests::cache_misses_behind_a_held_pool_share_one_fresh_read`: with a one-connection pool held for longer than every max age, eight concurrent misses on each of the three caches cost one database read, and each entry still lands fresh. - `tenant::tests::an_overlong_host_fails_closed_before_the_resolver`: a host over the limit fails as unmapped with no gate entry and no lookup; a host at the limit, including one in multibyte characters, is still looked up. - Mutation-checked: each of the following turns these tests red: stamping any of the three entries before the pool wait, dropping either new waiter path, letting waiters give up after the cache's max age, dropping the host length check, or counting the host length in bytes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 09:52:21 -05:00

It writes to stdout, not `audit_log`, so reads never take the audit advisory lock. The log is shaped for volume: one line per HTTP request, one line per WebSocket read, and one line per WebSocket connection. ## Lines per operation | Operation | Lines | |---|---| | HTTP request on a matched route | 1 (`http`), except the skip list below | | HTTP request matching no route | 1 (`http`, `route="<unmatched>"`) at status 400 and above, otherwise none | | WebSocket connection | 1 (`close`, carrying the login) | | WebSocket `REQ` / `COUNT` / NIP-AR sync | 1 each (`req` / `count` / `sync`), plus the `buzz_ws_reads_total` counter | | WebSocket NIP-42 login | 1 (`auth`) per decided or cut-off attempt, capped after the decision as below | | Audio login | 1 (`auth`, at its final admission check) | | WebSocket `EVENT` | 1 (`Event ingested`, not on the access target) | ## HTTP requests One middleware, `http_access_log`, writes every HTTP line. It sits between `track_metrics` and `http_trace_layer`, so rebuilt errors, body-limit refusals and localhost refusals all reach it. It writes the line when the response is ready, which is not proof the body was delivered. A request dropped before then logs `request=aborted` at WARN with no `status`. - Every line carries `route` (the matched route template, never the raw path), `peer_addr` when the listener has one, `status`, `time_to_response_ms` and `http_method` (the HTTP verb). The verb stays on the line itself because the `http.request` span is absent under an access-only filter and when a pending request is dropped. - Handlers record what they learn on the request's `AccessSlot`: the login (`method`, `pubkey`, `pubkey_verified`, `community`), the decision, the filter summary, and the route's own fields. The decision is `outcome` (`success` / `denied` / `failed` / `challenged`) with a fixed `reason`, or `undecided` when the route recorded none. A refusal is final: a later admission doesn't replace it, so a replayed NIP-98 proof that verifies and is then refused logs `failed` / `nip98_replay`. - `outcome` describes the login. What the route did is in `status` and the route's fields: a rejected `/events` write logs `outcome=success` with `status=400`, `accepted=false` and its `reject_reason`. - Route fields: - `/query` and `/count`: the filter summary and `result_count`. An incremental `/query` response (`{changes:[...]}`) counts its changes, removals included. Artifact reads record their summary before the query runs, so a read dropped mid-query keeps it. - `/events`: `accepted`, `kind`, `event_id`, and on a refused write the parse `category` / `line` / `column` or a fixed `reject_reason` (such as `invalid` or `restricted`), never the ingest message. - Invite mint: `invite_id`, `expires_at` and `max_uses`. Invite claim: `joined`. - Admin feedback attachment reads: `feedback_id` and `attachment_sha256`. With `BUZZ_ADMIN_AUTH=disabled` they log `method=network_trusted` with no key, and Host or Origin refusals log their fixed reason. - Every other route logs only the login fields. - No field can hold an invite code, a token, or a Blossom read hash. Media routes log the `/media/{sha256_ext}` template. - Skip list: NIP-11 and other non-upgrade requests on `/`, `/info`, `/.well-known/nostr.json`, `/health`, `/_liveness`, `/_readiness`, and the SPA and static files the relay serves when enabled (web assets, invite landing pages, git web pages, the admin bundle) at any status. Successful WebSocket upgrades (101) log no `http` line. Refusals before the upgrade on `/` and the audio path log one, with the status actually sent. - Routes that aren't Nostr-key logins (the command-token disconnect endpoint, the workflow webhook, the git server's internal callback) log `outcome=undecided` with no key. - Dev-mode `X-Pubkey` requests log `method=x_pubkey`, `pubkey_verified=false`. - A successful `/query` or `/count` that returned nothing (`result_count=0`) logs at DEBUG: on staging, 93% of `/query` lines were empty polls. Denied, failed, aborted and error reads, reads with no `result_count`, writes and logins keep their levels. - Other successful lines and git's credential-less first request (`challenged`, with its 401) are INFO. Refusals, statuses of 400 and above, and aborted requests are WARN. In Enforce mode the line records the remapped status (for example 403). Denial bodies and headers are unchanged. ## WebSocket reads - `REQ` / `COUNT` / `sync` lines carry `pubkey`, `conn_id`, `sub_id`, the filter summary, the outcome (`served` / `denied` / `aborted` / `error` plus a fixed reason), and `events_queued` (REQ and sync) or `count` (a COUNT that counted). A `REQ` is `served` only once its EOSE is queued to the client. A read logs WARN only when it ends in `error`. `served`, `denied` and `aborted` are INFO, since `aborted` means the read ended before completing: the client disconnected or sent CLOSE, a same-ID `REQ` replaced it, or the session was cancelled. - A NIP-AR sync subscription writes its `sync` line when its initial set completes, not when live delivery ends. Its summary is the registered live filter (kinds and channels, never artifact predicates), and `events_queued` counts the initial set. - `REQ` lines stay at INFO even when empty at EOSE, because the subscription can still deliver live events later. - Filter summary, shared with HTTP `/query` and `/count`: `kinds`, channel ids, authors and `p` values each list the first 10 distinct values. The exact `kind_count` / `channel_count` / `author_count` / `p_count` (summed per filter) appears only when the list is `*` or shows fewer values than the filters held. A dimension that any filter leaves open logs `*`. `since` / `until` / `limit` take the widest bound and are absent when any filter leaves them open, so no field understates what the read covered. `ids` is a count only. NIP-50 search logs `search: true`, never the text. Only well-formed channel ids and pubkeys are listed. An artifact read's summary uses only the standard dimensions of each raw filter, so artifact predicates and client-defined tags (such as `#1`) are never logged. The summary is skipped when the access target is off. Under `=warn`, every WARN line, HTTP or WebSocket, still carries it. - Per connection, only the first 16 reads that are refused before they run (`auth_required`, quota, concurrency, overload) or denied are logged. The rest are counted as `reads_suppressed` on the close line. A refusal that arrives after the close line has been written, from a read still running when the client left, logs its own line, so every refusal is either logged or counted, never both. Served reads are never capped. ## WebSocket read counter `buzz_ws_reads_total{type="req"|"count"|"sync"}` counts every parsed `REQ`, `COUNT` and NIP-AR sync frame before admission, exported at zero from startup. It is a metric, so it counts at any `RUST_LOG`, including production's current `error`. ## WebSocket logins A NIP-42 login writes one `auth` line when it is decided. A successful login logs INFO `outcome=success` at its commit point, decided under the connection's close-reason lock, so a disconnect racing the login (session expiry, admin disconnect, revocation, ban or roster removal) either wins, and the login logs no success, or loses and closes the connection right after the success line. A refused or failed login writes one WARN `auth` line with `outcome`, a fixed `reason` from the shared `AuthReason` code set, `pubkey` and `pubkey_verified`. Root WebSocket `auth` lines carry `peer_addr`. AUTH frames after the login is decided are capped at 16 per connection, and the rest are counted as `auth_suppressed`. An attempt cut off by close or session expiry logs `aborted`. Audio logins log one `auth` line at their final admission check. ## Connections The close line is the connection's only line. It is owned by the upgraded socket, so it is written exactly once however the connection ends: a normal close, a refusal while checking the community is active (`refused=not_admitted`), the connection limit (`refused=connection_limit`), or the handler being dropped. It carries `conn_id`, `community`, `peer_addr`, `duration_ms`, the login, `events_queued` / `bytes_queued` (frames the writer accepted and flushed, not client delivery), and the two suppression counters. ## Error text - Database errors log as `DbError::kind()` (SQLSTATE or variant), including the command-executor event insert. Search errors, on both read paths and in the search-cancel task, log as `SearchError::kind()` / the same SQLx classifier. Workflow database and webhook errors log as their codes, since webhook URLs can be secrets. - Git NIP-98 failures log a fixed code. Git subprocess stderr moved to DEBUG because hook output can contain message text. ## Operator notes `.env.example` documents the target, its `event` values (`http`, `auth`, `req`, `count`, `sync`, `close`), the skip list, the levels, and how to turn it down: `buzz_relay::access=warn` keeps refusals, errors and aborted HTTP requests, and of WebSocket reads only those that end in `error`, and `=off` drops everything. It also lists the removed lines: `NIP-42 auth successful/failed`, `WebSocket connection established/closed`, `event=connect`, `HTTP bridge request`, `Event ingested via pipeline`, `relay invite minted`, `relay member added via invite`, `admin feedback attachment read`, and `addr` (now `peer_addr`). JSON lines no longer repeat the current span as `span`, since `spans` already ends with it. A line logged under an explicit `parent:` span loses that parent's fields. The default OTel export filter sets `buzz_relay::access=off`, so access lines aren't exported a second time as span events. `peer_addr` is the TCP peer. `BUZZ_CLIENT_IP_HEADER` optionally names a request header (for example `cf-connecting-ip` behind Cloudflare or `x-real-ip` behind nginx, matched case-insensitively). When set, `http`, `auth` (root and audio), `close` and connection-limit lines also log `client_ip`: the rightmost comma-separated entry of the header's last field, only if it parses as an IP address. It never replaces `peer_addr`, and it is only trustworthy when every request arrives through a proxy that overwrites the header. --------- Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-11-03 17:48:59 -05:00
Will Pfleger	f6198f6997	feat(relay): record NIP-FI enforce denials at parity with shadow (#8974) ... ## What this does In enforce mode, NIP-FI denials used to be returned without a reason counter or a log line. This PR records enforce denials with the same `WouldDeny` reasons, label sets and log fields as shadow. **Admission behavior does not change**: statuses, close codes and frame order are all the same. - **`buzz_nip_fi_enforce_total{route,stage,outcome,community}`**: the same shape as `buzz_nip_fi_shadow_total`, including an `admit`/`admit` stage, so `1 - admit/total` is the enforce denial rate. Each socket or HTTP request gets exactly one verdict. - **`buzz_nip_fi_enforce_session_end_total{route,reason=expired|revoked,community}`**: once per admitted session. - **`buzz_nip_fi_enforce_strict_proof_total{route,outcome,community}`**: the outcome of the proof check that actually decided the request. Nothing is verified twice. - **Log lines** `nip-fi enforce deny` and `nip-fi enforce session end` (info, `mode="enforce"`, from `buzz_relay::nip_fi_shadow`). Shadow's `nip-fi shadow would-deny` gains `mode="shadow"`. Neither mode logs admits. ### How each verdict is recorded once - **Sockets (root, audio).** `EnforceSession` moves Pending → Admitted(pubkey) → Ended under one std mutex, and records inside the lock with no awaits. - Root admits at its AUTH commit; audio admits at its join commit. - A refusal for a non-NIP-FI reason retires the session without a record. Audio retires it before rollback. - A deadline the effect gate sees before the expiry worker is claimed at that seam. - **Ends.** Revocation and expiry are recorded only by the terminal transition that wins (`publish_authorization_denied`), and only while the socket isn't already cancelled. A community close or cancellation that wins first records nothing. - **HTTP.** The router guard scopes each enforced request with one verdict. An agent token's verdict is deferred to the end of the request: - the first owner-decided refusal is the verdict, otherwise the request was admitted; - membership rechecks, batches, Git success and early returns each count once. - **Owner provenance** comes from the decision itself (`BanVerdict{outcome,source}` from one `restriction_state` read), with no rereads. - Reasons: `owner_banned`, `owner_ban_unavailable`, `not_stored_owner`, `owner_link_unavailable`. - When the agent's own ban read fails and there's a token owner, the result is `owner/unavailable`, as shadow records it. - A ban or failed restriction read that ingest catches on `POST /events` after membership passed replaces the request's admit with `owner/denied` when the owner's row decided the ban, or `owner/unavailable` on a failed read. An agent's own ban is not recorded as its owner's. ## Shadow-to-enforce map | Shadow signal | Enforce counterpart | |---|---| | `buzz_nip_fi_shadow_total` denials: upgrade, guard, HTTP admission, AUTH pairing, deny set, stale binding | `buzz_nip_fi_enforce_total` with the same stage/outcome, plus a `nip-fi enforce deny` line | | `buzz_nip_fi_shadow_total` owner stage: ws, audio, http | the same, from the original decision: root/audio ban seam and owner link; HTTP `enforce_membership`, smart Git, Git settings, buzz/v1 ban reread | | `buzz_nip_fi_shadow_total` `deadline/session_deadline` (pending) | `EnforceSession::expire`, from the worker's winning terminal or the effect gate that saw it first | | `buzz_nip_fi_shadow_total` admit | `buzz_nip_fi_enforce_total{stage="admit",outcome="admit"}`, one per socket or request | | `buzz_nip_fi_shadow_session_end_total{reason=expired\|revoked}` | `buzz_nip_fi_enforce_session_end_total`, same labels | | `buzz_nip_fi_shadow_strict_proof_total` | `buzz_nip_fi_enforce_strict_proof_total`, from the deciding check (a rejection is the route's 403, or 401 when the proof is missing) | | `buzz_nip_fi_shadow_disconnect_total{admin,accepted}` | `buzz_nip_fi_disconnect_total` (`api/nip_fi.rs:160`) | | `buzz_nip_fi_shadow_disconnect_total{admin,propagation_failure}` | `buzz_nip_fi_disconnect_propagation_failures_total` (`api/nip_fi.rs:180–185`) | | `buzz_nip_fi_shadow_disconnect_total{admin,capacity}` | `buzz_nip_fi_disconnect_capacity_rejections_total` (`api/nip_fi.rs:196–201`) | | `buzz_nip_fi_shadow_disconnect_total{cross_pod,capacity}` | `buzz_nip_fi_cross_pod_capacity_exceeded_total` (`api/nip_fi.rs:433–434`) | | `buzz_nip_fi_shadow_disconnect_total{cross_pod,poison}` | `buzz_nip_fi_cross_pod_shard_poison_total` (`api/nip_fi.rs:442–443`) | | `buzz_nip_fi_shadow_disconnect_total{cross_pod,lag}` | `buzz_nip_fi_disconnect_lag_total` (`main.rs:1596–1602`) | The enforce series was renamed from `buzz_nip_fi_enforce_denied_total` to `buzz_nip_fi_enforce_total` when it gained the `admit` stage. ## Tests Infra-free, in the `test-unit` lane: - `state::enforce_end_is_recorded_only_by_the_winning_terminal`: root scan, audio scan and deadline, each against a community close or cancellation first and FI first. - `nip_fi_http::enforce_strict_proof_records_the_deciding_check_once`: pass and reject, and no record when cardinality refuses. - `nip_fi_shadow_session::audio_owner_link_refusal_shares_roots_seam_and_reasons`: calls the shared owner-link helper with route `audio`, not a huddle socket. - The existing shadow, upgrade, router and HTTP enforce tests. Postgres lane: - `handlers::auth::enforce_root_auth_records_owner_refusals_from_one_decision`: clean admit then `expired` through the real expiry worker; banned token owner, banned stored owner, other stored owner and a failed ban read; authorization reads counted from the decision only. - `handlers::auth::enforce_root_deadline_seen_by_the_gate_first_is_recorded_once`: both orderings. - `audio::handler::enforce_join_commit_is_the_audio_admission`: drives the join-commit seam directly, not a huddle socket or the expiry worker: committed then expired; archived with an expiry held inside the rollback; gate-first deadline. - `api::bridge::token_owner_reaches_membership_on_every_nip_fi_http_route`: one verdict per request on every NIP-FI HTTP route, including sidebar, read-state, Blossom and Git, for an owner ban, a stored-owner conflict and a clear owner. - `api::bridge::token_owner_ban_reread_is_the_fixed_nip_fi_denial_on_http`: own ban, owner ban and unavailable at the reread, on sidebar and Git settings. - `api::bridge::token_owner_publish_ban_is_the_fixed_nip_fi_denial_on_http`: a late ban or failed read on `POST /events` at the write, typing, moderation and relay-admin checks records exactly one owner denial and no admit when only the owner is banned, and no owner denial when the agent alone or both are banned. - `audio::handler::tests::already_expired_audio_bootstrap_records_the_deadline`: an already-expired bootstrap records `deadline/session_deadline`, not a deny-set denial. Each new test names the mutation that turns it red. These were run red: - deleting root's `session.admit(pubkey)` - deleting audio's commit `session.admit(pubkey)` - deleting `effect_refused` - deleting enforce from `retire_shadow` - deleting the commit seam's `expire` - deleting the cancellation guard - deleting the own-read-failure provenance --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-11-03 14:21:32 -05:00

Luke Tornquist	d44031f418	perf(relay): cut writer-pool round trips past the 48k relay ceiling (#8846) ... ## Summary Five changes that take load off the writer pool and the relay's connection bookkeeping. On a single-relay load rig, the clean ceiling moves from 40k to about 48k WebSocket clients. In the A/B, connect p99 at 48k fell from 4.1 s (abort) to 1.65 s. 1. **Ban/mute restriction cache with a 1 s max age.** HTTP API requests, publishes and ephemeral writes read `(community, pubkey)` restriction state through one cache. An entry is served for 1 s from when its read began, matching the open-channel cache's bound. Socket admission, moderation-command actor checks and the `/buzz/v1` ban recheck still read fresh. An admitted socket outlives the 1 s window, so a banned client that reconnects inside it would otherwise keep a socket open indefinitely. A ban drops the target's entry, and each owned agent's entry, on every pod as part of the live-disconnect fan-out, best-effort. Timeouts, untimeouts and unbans drop it on the pod that handles them. 2. **Fewer round trips per event read.** Replica reads skip the per-read `statement_timeout` tighten, because the reader pool installs the deadline at connect. They keep the savepoint, so a failed or cancelled read leaves the session usable and releases its locks. That takes them from 4 round trips to 3. Writer reads send `BEGIN` and the tighten as one message, which also takes them from 4 to 3. 3. **Concurrent open-channel cache misses share one read.** The first miss in a community takes a per-community gate and reads; the others wait for it and use its result. A waiter whose leader failed reads once on its own and does not queue again. A waiter also stops waiting after the cache's 1 s max age and reads on its own, because the leader's set would be stale by then anyway. So a leader whose read hangs stalls only its own request. 4. **`has_admitted_connection` is one map lookup.** A `(community, pubkey) → admitted count` index is maintained under each socket's pubkey lock in `mark_admitted`, `set_authenticated_identity` and `deregister`. It replaces a scan of every connection on each disconnect. 5. **Host → community cache with a 1 s max age.** Only successful lookups are cached; unmapped hosts and errors go to the database every time. ## What got simpler - The ban handler's separate pod-local cache drop is gone; the disconnect every ban already runs covers it on every pod. - One write-restriction gate instead of two. `enforce_cached_write_restriction`, `enforce_relay_membership_ephemeral` and the `cached_ban` parameter chain through `enforce_membership` / `admit_member` / `deny_banned` are deleted. - The ephemeral path's separate 30 s ban cache is gone, so the relay has one staleness rule for restriction state instead of two. ## Notes - Bans reach the restriction cache on every pod. Every ban path (signed command, report action, relay admin) closes the target's and its agents' sockets clusterwide, and each pod drops those entries in the same step. A dropped Redis publish, or a restriction read already in flight when the drop lands (it can refill the old row), falls back to the 1 s bound. Timeouts on other pods also rely on the 1 s bound, and so do unbans and untimeouts, which fail closed. - On the load rig the restriction-cache hit rate was 28%, because HTTP agents poll every 5 s. A longer TTL with Redis invalidation would raise it, but that is a separate change. ## Load test Single relay pinned to 8 cores, native Postgres 16, a seeded fixture with 2,000 open channels, and a 6-shard generator. Steady ramp with 120 s holds; a step aborts at p99 > 3 s. Each step adds 10% HTTP agents. | clients | base connect p99 | this PR connect p99 | base relay cores | this PR relay cores | |---|---|---|---|---| | 32k | 34 ms | 31 ms | 1.71 | 1.66 | | 40k | 45 ms | 26 ms | 2.33 | 2.15 | | 48k | 4,107 ms (abort) | 1,652 ms | 4.7 | 3.0 | | 56k | n/a | 4,535 ms (abort) | n/a | 4.0 | Open-channel re-reads over the run fell from 72k to 1.6k. The tenant cache hit rate was 94%. 48k is this branch's knee. A later run of the same build aborted at 48k: connect p99 2.2 s, but 29% subscribe errors from the concurrent-handler cap. With a 10 s restriction max age, it passed 48k, at connect p99 1.56 s, 60% hit rate and 10% fewer relay cores, and both arms stopped at 56k. ## Testing - `cargo fmt --check`, `cargo clippy -p buzz-relay -p buzz-db --all-targets -D warnings` - `cargo test -p buzz-db --lib` and `-p buzz-relay --lib`, run in parallel. The only failures were 8 DB-seeding tests that need a migrated default database; the Postgres lane covers them. Commits after that run changed the replica savepoint, the `/buzz/v1` recheck revert and some test edits. - Postgres lane at head: `scripts/postgres-test-run.sh -p buzz-relay -p buzz-db --lib --bins --tests`. All 1,183 tests passed. - Mutants. Each one must turn its new test red: - waiters skipping the gate - a no-op index removal - the tenant cache ignoring age - the restriction cache ignoring age - a waiter waiting on the gate with no limit - a disconnect that keeps the cached restriction row - replica reads dropping the savepoint buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 11:15:49 -05:00
Luke Tornquist	02925ceb6e	fix(relay): cap bridge searches in flight per user (#8956) ... ## Summary Typeahead starts a bridge `/query` search on almost every keystroke. The client aborts the previous request. But if the abort never reaches the relay, for example because an intermediary keeps the upstream request open, every one of those searches keeps running. Each `(community, pubkey)` may now have **4** bridge searches in flight. The next search supersedes the oldest one. The superseded request returns **409** `{"error":"search superseded by a newer search"}`. It is deliberately not a 429: desktop arms its relay-wide admission gate on any 429, which would hold every relay request for 10 s, and the CLI retries a `rate-limited:` 429. Its future is dropped, so #8954's cancel-on-drop cancels its statement on the server. - **Newest wins.** The newcomer is never rejected, because the newest keystroke is the one the user is waiting for. - **The cap is above 1.** Sessions that share a pubkey keep their parallel searches: several agent sessions, or people search and message search running side by side. - **Bookkeeping lives in process.** `SearchSlots` holds a `Mutex<HashMap<key, VecDeque<(id, CancellationToken)>>>`. A slot removes itself by id when its search finishes, fails, is dropped or is superseded. So a superseded search can never remove the newer search that replaced it, and a user's entry is removed when their last search leaves. - **A search that finishes as it is superseded still returns its result.** The `select!` is biased toward the search. The limit is per relay process, not global. That is enough to bound how much one user can pile onto one process's search pool. ## What got simpler Nothing was removed. The change adds one small, self-contained module and one call site. It also wires the new tests into the unit lane (`Justfile test-unit` and `scripts/run-tests.sh`). The relay's unit lane is an allowlist, so without that wiring the tests would run nowhere in CI. ## Tests `api::bridge::search_slots::tests`: - `the_search_past_the_cap_supersedes_the_oldest` - `a_finished_search_frees_its_slot` - `a_superseded_search_leaves_its_successor_in_place` - `no_entry_outlives_its_searches` - `a_superseded_search_is_a_conflict_not_back_pressure` Each of these mutants made at least one test fail: - Removing the cap. - Replacing the by-id removal with `pop_front`. - Leaving empty user entries in the map. - Answering supersession with 429. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 00:33:09 +00:00

Logan Johnson	5f8d0aab98	fix(relay): refuse a second listed open channel with the same name (#8782) ... ## Summary Two open channels in one community could have the same name, so the channel list showed two `#square-ios` rows and people could not tell them apart. Now the relay refuses to create, rename or open up a channel when that would give it the same name as another channel in the channel list, ignoring case. The client gets `invalid: an open channel named "…" already exists`. The rule follows Slack: an archived channel keeps its name until it is deleted. Private channels, DMs and unlisted channels may still repeat names. So a refusal never reveals that a private channel exists. The PR also adds a script that renames the duplicates that exist today. It sends each rename through the relay, so relays keep serving while it runs. The stacked PR https://github.com/block/buzz/pull/8787 then adds a database index that enforces the rule. This PR is the release that must be fully deployed before that index. ## Details **Which channels the rule covers.** A *listed* channel: open, not unlisted, a stream or forum, not deleted. Archived channels are included. The check runs on create, rename, private → open and unlisted → listed. **Relay check** (`crates/buzz-db/src/store/channel.rs`, `crates/buzz-relay/src/handlers/ingest.rs`): - The check runs after the write, in the same transaction, under a per-name lock. So two concurrent writers cannot both commit the same name. - A refused create or edit (kind:9007 or kind:9002) gets `OK false "invalid: an open channel named … already exists"`. Nothing from it is stored. - The relay gives the same answer when the database index from https://github.com/block/buzz/pull/8787 refuses the write. That covers the rollout, and a rollback from that release. - A channel create with no `h` tag (the new channel's id) is now refused before it is stored. Before, such a create ran after the event was stored, so a refusal (for example, a taken name) still answered "accepted". All first-party clients send `h`. **Operator rename** (`crates/buzz-relay/src/handlers/side_effects.rs`). The rename script needs to rename channels it does not own, archived ones included. So a relay operator may now send a channel edit that changes only the name of a listed channel. Everything else still needs the channel's owner or admin. - "Operator" means `RELAY_OPERATOR_PUBKEYS`, the owner fallback, or an `operator` row in `relay_operators`. A moderator is not an operator. - The rename also applies to an archived listed channel, whatever the operator's role in that channel, and the channel stays archived. Other edits of an archived channel are still refused. - Private channels, unlisted channels and DMs still need the channel's owner or admin. The relay decides "listed" under the channel row lock, so a channel made private during the rename is not renamed. - The rename takes the normal edit path: the name check, the stored event, the channel metadata event and fan-out. **Rename script** (`scripts/maintenance/rename_duplicate_listed_channel_names.sh`, with the read-only plan `plan_duplicate_listed_channel_renames.sql`): - In each group of listed channels that share a name, the oldest unarchived channel keeps the name. Each other channel becomes `<name>-<first 8 chars of id>`, or `<name>-<id>` when that is also taken. When all the channels in a group are archived, the oldest keeps the name. - **Starter channels.** Released desktop and mobile apps create `#general` and `#welcome-everyone` when a community has no open, unarchived stream with that name. Under the new rule, the relay refuses that create while an archived channel has the name, and the apps' setup fails. So the script also renames `general` and `welcome-everyone` when every listed channel with that name is archived. That frees the name for the apps. - The apps create each starter at a fixed id, derived from the relay's address. If a channel already has that id, the relay refuses the create there whatever its name, so a rename cannot help. For that name the script renames nothing, and an archived starter at its id keeps the name. The script computes the ids from `BUZZ_RELAY_URL` (or `BUZZ_STARTER_ORIGIN` when the apps use a different address) and prints them, so the operator can check them against a client. A relay-side fix for those clients is planned separately. - The operator key goes in `BUZZ_PRIVATE_KEY`. It must be a relay operator and a member of the community. The script stops at the first auth refusal and says so. - The script stops before the plan for an unknown host, an archived community and a community being deleted, and says what to do. - A failed rename (the new name is now taken, or the relay can't be reached) is reported, and the script goes on. At the end it reads the plan again and exits 1 if any rename remains. `--dry-run` prints the plan. - The script replaces the earlier direct-SQL repair and `buzz-admin reconcile-channels --metadata`, which needed every relay pod stopped. **Duplicates that exist today** (read on 2026-10-30): `ml-platform-public` (`d41a31f8…`, `7be55f5a…`) and `square-ios` (`79f8e9d4…` archived, `fe246d3e…` live). ### Rollout The full procedure, with exact SQL and recovery steps, is in `docs/channel-name-uniqueness-deployment.md` in https://github.com/block/buzz/pull/8787. 1. **Deploy this PR.** Wait until no older relay pod serves; check the image of every pod. An older relay can still create a duplicate, and it refuses the operator rename. 2. **Rename the existing duplicates in each community**, with relays serving. The key must be an `operator`, not a moderator, and a member of the community (`RELAY_URL=wss://<host> buzz-admin add-member --pubkey <npub>`). ```sh DATABASE_URL=postgres://... BUZZ_PRIVATE_KEY=<operator key> \ scripts/maintenance/rename_duplicate_listed_channel_names.sh --dry-run <community host> # review the plan, then run it again without --dry-run ``` For the duplicates known today, the newer `ml-platform-public` and the archived `square-ios` (`79f8e9d4…`) get the `-<id8>` suffix. 3. **Confirm that no duplicate remains** in any community (query in the doc). 4. **Build the index, then deploy https://github.com/block/buzz/pull/8787.** Rollback from https://github.com/block/buzz/pull/8787 goes to this release only, keeping the index, with auto-migration off. ### Related issue None found. ### Testing - **Live local relay.** The script ran against a local relay built at 9ee09a619, with relay membership required and six seeded channels (`ops`, `OPS`, an archived `Ops`, a private `ops`, `dev`, `DEV`): - `--dry-run` listed the three renames. - With the operator key not yet a member, the script stopped at the first refusal, named the membership precondition and renamed nothing. - After `buzz-admin add-member`, it renamed all three and exited 0. The archived channel stayed archived, the private `ops` kept its name, and a second run renamed nothing. - With the community archived, the script stopped with the unarchive message. - Rerun at 0df245e3c as part of the full rollout in https://github.com/block/buzz/pull/8787: the relay refused a new duplicate over the wire, and the script renamed the seeded duplicates with the relay serving. - **Relay tests** (`group_state_postgres_tests.rs`): a taken name is refused as `invalid:` and nothing is stored; a create with no `h` tag is refused before it is stored; an operator can rename only a listed channel, only the name, archived or not, and a moderator cannot; an operator rename is refused if the channel stops being listed before it is saved. - **Store tests** (`channel_name_postgres_tests.rs`): create, rename, private → open and unlisted → listed are refused for a taken name; private and unlisted names may repeat; an archived channel keeps its name and a deleted one frees it; of two concurrent creates with one name, the second is refused once the first commits. - **Plan and script tests** (`listed_channel_name_postgres_tests.rs`) run the shipped SQL and shell script: which channel keeps the name, the starter cases, names at the 255-character limit, names with control characters or a leading `-`, and the auth and community stops. The starter-id computation matches the mobile app's test vectors. - The new guards were each removed once to confirm that a test fails. - The full local Postgres test runs (buzz-db, buzz-relay, buzz-admin) pass, except 6 tests that also fail locally on main and pass in CI. ### Database review checklist - [x] Phase: writer release (deploy), plus a maintenance script. The stacked PR adds the contract index; this release is its required stop. - [x] No trigger, function, procedure, rule or foreign key. - [x] No migration. The script writes nothing to the database itself. It reads a plan, and the relay applies each rename as a normal channel edit. `docs/database.md` Rule 3 asks for maintenance scripts in their own PR. The script is here because it depends on the operator rename in this PR. - [x] Contract: not in this PR. - [x] Rule 4 locations: no schema change. - [x] Deployed relay: the schema is unchanged, so the deployed relay keeps working. An older relay refuses the operator rename, so run the script only after this release is fully deployed. This release also works beside the contract index (tests above). - [x] Timeouts: no index build or bulk write here. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-02 13:23:40 -05:00

klopez4212	634f48a8bd	Mobile: open Solo chats with Bestie and workspace controls (#8884) ... Mobile New chat now opens directly with the synced Bestie selected. The first send creates and names the chat; leaving an empty draft creates nothing. New and existing Solo chats can select or clear a workspace from the header popover, with a checkmark for the active choice and a No Workspace option. Workspace and agent controls have separate iOS glass surfaces, Bestie stays at the far right, and Back uses a chevron. The agent sheet fits its list, with scrolling for long lists. Workspace creation stays in the Home New menu. The New menu groups Solo above Team. Android expands across the full control row; iOS keeps its native menu while Search and Bestie merge into New through Liquid Glass, with synchronized icon motion and the residual glass fading away. Empty workspaces use a compact, muted message. Validation: 4,055 mobile tests passed (34 skipped), static analysis passed, and native menu checks passed. Earlier physical-device previews and the iPhone New-menu animation were visually approved before this consolidation. This PR consolidates the controls previously developed in #8891 into the existing draft/first-send implementation. The New menu animations, attachment handling, and durable retries remain in this PR.

Matt Toohey	eafd77e9f6	ci: bound Hermit fetches and let relay builds run without sccache (#8739) ... ## Summary Two CI-workflow fixes from the 23–30 Oct flake audit. This is one of six PRs split from the reviewed `flakey-tests` branch (siblings below). Each PR applies on its own to `main`. ### Hermit tool downloads (5 runs, 1 on main) - **Runs:** 40635610550 and 40941660945, in Detect Changed Paths (`node`). The selection step printed nothing for 9–10 min, the job hit its cap, and every gate failed as cancelled. Three more, 40373404267 on main (PostgreSQL Tests and Desktop E2E Integration 1/3, `pgschema`), 40373003333 (Mobile Android, `cmake`) and 40373467575 (Desktop Build macOS, `just`), got 504s during GitHub's release-asset outage on 10-26, ~17:54–18:00 UTC. - **Cause:** jobs start with an empty Hermit cache, so a tool's first call downloads it, with no deadline. Hermit v0.54.1 tries three times, a second apart, then gives up. - **Change:** a new `scripts/ci-hermit-retry.sh` runs a no-op tool command with a 90 s deadline per attempt, three attempts and 15 s × n backoff. The deadline is plain bash: job control gives each attempt its own process group, which gets TERM and then KILL. macOS runners have no `timeout(1)` and may run bash 3.2. A "Fetch Hermit tools" step calls it for: - `node` and `just` in Detect Changed Paths, where one stall cancels every gate. One `sh -c` invocation covers both, so the worst case is 345 s, inside the 10-minute cap. Two invocations would take 690 s. - `pgschema` in PostgreSQL Tests, Desktop E2E Integration and Backend Integration (via `--help`, since it has no `--version`). - `just` and `cmake` in the Android lane. - `just` in Desktop Build (macOS). The test, `scripts/ci-hermit-retry.test.mjs`, joins Detect Changed Paths' `node --test` list, and the script joins the rust and mobile path filters. One stalled attempt costs ~105 s, which fits every job's cap. - A killed attempt doesn't break the retry. Hermit downloads to a temp file and unpacks to a temp dir, and renames each into place only once it's complete. Its lock is a kernel flock. ### sccache storage failures (2 runs) - **Runs:** 40355289475 (Desktop E2E Relay postgres-tests, 10-26, "Egress is over the account limit") and 40714034945 (relay-binaries, 10-28, "send http request"). - **Cause:** the sccache server checks its GHA cache storage at startup and won't start if that fails. Cargo's first `sccache rustc -vV` spawns it, so the build fails. `SCCACHE_IGNORE_SERVER_IO_ERROR` doesn't help here: in v0.16.0 it is read only when a running server's compile response fails. - **Change:** a "Start sccache" step runs `sccache --start-server`. It outputs `wrapper=sccache`, or an empty wrapper and a warning if the server won't start. The three build steps take `RUSTC_WRAPPER` from it, and cargo treats an empty `RUSTC_WRAPPER` as no wrapper. - The fallback doesn't fail the job later, in sccache-action's post step. At the pinned fc920bf, that step runs `sccache --show-stats` and the JSON form, and fails the job if either exits non-zero. With no server running, v0.16.0's `--show-stats` doesn't start one. It returns zero stats from the client side and exits 0. So the step keeps its stats annotation, and `disable_annotations` stays unset. ### Related issue None found. **Overlaps #8213** ("ci: fix empty root-workspace Rust caches and merge test-unit nextest runs"). #8213 already conflicts with `main`, and this PR adds a conflict in `.github/workflows/ci.yml` (path filters). ### Testing Verified locally: - With a fresh Hermit state dir, `node` was SIGKILLed mid-download, then mid-unpack while holding the lock, then stopped with TERM by the script's own 1 s deadline. Each retry produced a working v24.15.0, at clean-unpack speed. The `sh -c` form fetched both tools, and a 1 s deadline on `sh -c 'sleep 37 && ...'` stopped `sh` and its child, leaving no orphan. Tested under macOS bash 3.2 and Debian bash 5.2. - sccache v0.16.0 (aarch64-apple-darwin) ran against a GHA cache whose `ACTIONS_RESULTS_URL` refused connections, in READ_ONLY and READ_WRITE modes. `--start-server` exited 2 ("Server startup failed: cache storage failed to read"). Both `--show-stats` forms then exited 0, with zero stats and valid JSON. `--stop-server` exited 2, which shows no server had started. Only hosted CI can show: - the script under the runners' real shells, and that healthy runs only pay a few seconds; - whether ~3 min of spaced attempts rides out the next outage. The 10-26 outage lasted ~6 min, longer than this covers; - that the explicit `--start-server` behaves like cargo's implicit start against the real GHA cache. The fallback branch needs a storage outage to run in CI. Not covered here: first fetches of other tools (rustup, uv, pnpm) still have no deadline. A per-job Hermit package cache is the follow-up. Pushed with `git push --no-verify`, because the pre-push suites fail when the laptop is under load. ### Readiness An agent review of the combined `flakey-tests` branch (b432453af) found no blockers. `buzz-review-completed` is not added, because the human test step (AGENTS.md "Before opening a PR", step 3) hasn't happened yet. ### Siblings - #8740 test(relay): thread_window aux-page hold and `api::media` Postgres tests - #8741 test(mobile): RunnerTests title fade and alert wait - #8742 fix(desktop): deep-linked message hold (product change) - #8743 test(desktop): four specs racing scroll settles and focus - #8744 test(desktop): five settle classes and remote-owned-mentions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-31 11:47:39 +11:00

Matt Toohey	158b3bf562	test(scripts): stop file-size fixtures leaking git repos and fsmonitor daemons (#8727) ... ## Summary The file-size ratchet tests (`scripts/check-file-sizes-core.test.mjs`, run by `just file-size-check`) created fixture git repos under the OS tmpdir and never deleted them. When `core.fsmonitor=true` is set globally, every git call in a fixture also started a `git fsmonitor--daemon` that never exited. So every run left more temp repos and more daemons behind. - The test's `git()` helper now passes `-c core.fsmonitor=false`, next to the existing `core.hooksPath` override. - Fixture repos are now created through a new `createFixtureRepo()` helper, which records each path. An `after()` hook deletes them all with `rmSync(..., { recursive: true, force: true })`. The other scripts that create temp git repos (`scripts/ci-selection.test.mjs`, `scripts/flake-check.test.mjs`, `scripts/test-mobile-release-contract.sh`, `scripts/test-sprig-image.sh`) already clean up their temp directories and left no daemons running, so they are unchanged. ## Testing - `node --test scripts/check-file-sizes-core.test.mjs`: no `file-size-*` directories are left in the tmpdir afterwards, and no new `fsmonitor--daemon` processes are running. - The pre-push `file-size-check` lane passes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-30 14:37:38 +11:00
Matt Toohey	fae3f0346c	test(mobile): keep late callbacks and fixed sleeps from failing tests (#8678) ... ## Summary Fixes three mobile flakes from the 21–28 Oct 2026 CI runs, in test code only: - In two iOS `RunnerTests` classes, late bridge callbacks no longer fail whichever test is running when they fire. - The waits on a busy test-host main thread now cap at 10 s. - Two Flutter avatar tests poll for the ready frame instead of sleeping a fixed 50 ms. This is one of seven PRs split out of the `flakey-tests` branch (siblings below). ### Related issue None found. ### Flaky tests fixed | Test | Failing runs | Cause | Change | |---|---|---|---| | `BuzzPushSnapshotEnrichmentTests` (RunnerTests) | 40362671989 (job 121712747802, main), 39681273328#1 (job 119504560518), 40658588384 (job 122715950541, PR #8640) | The 1 s waits ran out while the test host's Flutter app held the main thread, and the test returned and deleted its temp directory. The bridge callback's assertions then ran later and were blamed on whichever test was running (`ProfileSetupRecoveryTests`, `IdentityFilePluginTests`). | Callbacks only record the value and fulfill. Every assertion, including the `isRestricted` checks, runs after the wait, so a late callback writes into a dead local. The seven waits cap at 10 s (`callbackTimeout`). | | `ProfileSetupRecoveryTests` `testStartedEditorWithoutReadyRestoresProfileAndAllowsRetry` | 40585805357 (job 122477274956, PR #8568) | Engine release and editor dismissal must both happen within 2 s, on the main thread the host app keeps busy. | Both predicate waits cap at 10 s. | | Flutter `channel_detail_page_test.dart` "profile sheet shows the poster before autoplay and restores it on tap" and `settings_profile_header_test.dart` "shows the poster until the animated avatar is ready" | 40368315739 (job 121732711851, main) | After the image response is released, both tests slept a fixed 50 ms of real time before `pumpAndSettle`. A slower real decode left no frame scheduled, so the ready key was missing. | A new `WidgetHelpers.pumpUntilFound` pumps in 10 ms real-time steps until the ready key appears, capped at about 5 s. | Local evidence is from the original `flakey-tests` commit (53aaec97c), Xcode 27.1 on the iOS 26.2 simulator: - Enrichment, with `Self.complete` delayed 1.5 s and 4 s: 6 failures before, 107/107 after. With a 12 s delay, every failure lands in its owning test. A mutated error code is still caught. - Profile setup, with the engine release held 4 s: 2 failures before, 4/4 after. A leaked engine still fails. - Avatar tests: under load, 94/96 before and 96/96 after. With a 200 ms image delay, 0/5 before and 5/5 after. A widget that never signals ready still fails. Not included: - The planned `AppDelegate` / `Runner.xcscheme` change that keeps Flutter out of the RunnerTests host. It did not work locally: restored scene sessions and the `UIMainStoryboardFile` fallback, and a normal launch came up black afterwards. - `IdentityFilePluginTests` `testSyntheticDocumentsReadInPlaceAndRejectInvalidOrOversize` (40441255307#1). It is left unchanged and stays open. ### Verification This branch was pushed without local re-verification, by the user's choice: local test runs were overloading the machine and failing for that reason. **Hosted CI is the check.** It was pushed with `git push --no-verify`, because the pre-push hook runs the Flutter tests. - Every file is byte-identical to its final version on `flakey-tests` (67185df6a). - Checked for this PR: `git diff --check`, and a conflict-free merge with all six siblings onto `main`. - #8613's flake-check lane will repeat the two changed Dart test files. ### Readiness Test-only change. AGENTS.md's readiness steps (agent review, then human confirmation) are still outstanding, so `buzz-review-completed` is not set. ### Merge order Independent of the other six. It merges cleanly onto `main`, and with every sibling, in any order. ### Sibling PRs Split from `flakey-tests` (one PR per area): #8676 (PostgreSQL lease + lane), #8677 (relay E2E helper + Windows shell), #8679 (Tauri apt cache + Windows Rust cap), #8680 (desktop product races), #8681 (desktop E2E state gates), #8682 (desktop E2E composer + row actions). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Jitter <2b2e6415e748c35180847a37aadae06a11e30dddc76b784e7fd9354c4eb42e7a@buzz.block.builderlab.xyz>	2026-10-30 11:58:40 +11:00
Matt Toohey	b1f76ef4d2	ci: cache the Tauri apt .debs and fit a cold Windows Rust run in its cap (#8679) ... ## Summary Fixes the two CI workflow defects that turned `main` red most often in the 21–28 Oct 2026 audit: - **Desktop Tauri:** the lane now caches its apt `.deb`s. It no longer re-downloads 62 MB from a slow Ubuntu mirror on every run. - **Windows Rust:** the lane drops a duplicate `cargo check` and gets a 60 min cap, so a cold run can save its cache. It also updates #8613's `scripts/flake-check.test.mjs`, which breaks once the Tauri package list moves into an env var. There are no product code or test-behaviour changes. This is one of seven PRs split out of the `flakey-tests` branch (siblings below). ### Related issue None found. #8613 touched both workflows after the audit, but not these steps. No open PR changes how the Tauri packages are fetched, the Windows timeout, or its Check (workspace) step: - #8422, #8321 and #8373 only add packages to the list, and would now add them to `TAURI_APT_PACKAGES`. - #8414 adds two mesh-llm Tauri steps to the Windows job. If it lands, they must fit the cold budget below. ### CI failures fixed | Lane / test | Failing runs | Cause | Change | |---|---|---|---| | Desktop Tauri, "Install Tauri dependencies (Linux)" (`_ci-desktop.yml`) | 62 jobs in 51 run attempts, 22–27 Oct. On main: 39821769576, 39822883395, 39827234118, 40333705511, 40342468627, 40348069929, 40353619362, 40368315739, 40373404267, 40374519539, 40556742929 | All 3 `ci-apt-retry.sh` attempts hit their 420 s limit while `azure.archive.ubuntu.com` served the 62 MB at 20–65 KB/s. The 25.5 MB `libwebkit2gtk-4.1-0` alone takes a whole attempt, and each attempt loses its partial download. | The package list moves to a job-level `TAURI_APT_PACKAGES`. A new "Resolve Tauri apt archives" step builds the cache key from `apt-get install --print-uris -o Acquire::ForceHash=SHA256` (name, size and SHA256 per file). `actions/cache/restore` uses that key. The install step copies only the restored files whose SHA256 matches the signed index, because apt 2.8.3 reuses any same-size cached `.deb` without hashing it. A best-effort rebuild keeps exactly the listed files. `actions/cache/save` runs only on core-lane pushes after a successful rebuild; PR runs never save. | | Windows Rust (`_ci-rust.yml`) | All on main: 39796569342 (job 119885795086), 39821769576 (119975358772), 39827234118 (119994286695), 39865872891 (120128351939), 40402556064 (121852634685) | Every test passed. Cold steps take 41.3–43.5 min, so the 45 min cap cancelled the `Swatinem/rust-cache` post-run save 1.6–3.7 min in. No cache was written, and the next push was cold again. | Delete "Check (workspace)". The clippy step before it covers the same `--workspace --all-targets` set with `-D warnings`, which saves 2.0–2.8 min. Raise `timeout-minutes` from 45 to 60, with the measured breakdown in a comment: 39–41 min of steps, a ~4.5 min save and ~15 min of margin. | | `scripts/flake-check.test.mjs` "repeat invocations mirror the lanes they stand in for" | None in CI yet: it fails only with this change applied | #8613 added this test after `flakey-tests` branched. It checks that the advisory `flake-tauri` lane installs the same packages as the Desktop Tauri core lane, by regex-matching the inline `apt-get install -y --no-install-recommends \` list in `_ci-desktop.yml`. That list now lives in `TAURI_APT_PACKAGES`, so the regex matched nothing and the test failed with "Desktop Tauri apt packages". | Read `TAURI_APT_PACKAGES` from `_ci-desktop.yml` and compare package names (12 on each side) with `_ci-flake.yml`'s list. Renaming one package in `_ci-flake.yml` still fails the test. Giving the `flake-tauri` lane the same read-only `.deb` restore is a follow-up. | Local evidence is from the original `flakey-tests` commit (9aa768a3b): - The apt steps ran verbatim in Ubuntu 24.04 containers with apt 2.8.3, with the cache restore and the save step's `if:` emulated. - On a miss, the install fetches everything ("Need to get 254 MB"). On an exact hit with the network down, it fetches nothing ("Need to get 0 B/254 MB"). - On a fallback with one `.deb` missing and one corrupted at the same size, the hash check rejects the corrupt file, and apt re-fetches only the corrupt and missing files. - The key was identical in all four simulated jobs. - The Windows numbers come from the jobs API for the five runs above. On this branch, the split session ran the `scripts/` node tests: `ci-selection`, `ci-required-gates`, `ci-apt-retry` and `flake-check` on macOS gave 84 pass, 0 fail and 8 skipped (Linux-only). Before the `flake-check.test.mjs` fix, that test failed 1 case. The same session ran actionlint 1.7.12 with shellcheck, which was clean, and the rust-cache contract scripts, which passed. ### Verification This branch was pushed without further local re-verification, by the user's choice: local test runs were overloading the machine and failing for that reason. **Hosted CI is the check.** It was pushed with `git push --no-verify` over SSH. The pre-push hook runs tests, and the HTTPS token lacks the `workflow` scope. Only hosted CI can show: - The runner's real package list (about 62 MB) and the same key in all three Tauri lanes. - The `actions/cache` round trip. The first PR run misses, because `main` has no key yet. After merge, the first push to `main` saves it. - A cold Windows run saving its cache within the new cap. The next toolchain bump or cache eviction will show it. Remaining risk: after Ubuntu updates a large package, runs fetch it from the mirror until a push to `main` saves a new key. ### Readiness CI-only change. AGENTS.md's readiness steps (agent review, then human confirmation) are still outstanding, so `buzz-review-completed` is not set. ### Merge order Independent of the other six. It merges cleanly onto `main`, and with every sibling, in any order. ### Sibling PRs Split from `flakey-tests` (one PR per area): #8676 (PostgreSQL lease + lane), #8677 (relay E2E helper + Windows shell), #8678 (mobile), #8680 (desktop product races), #8681 (desktop E2E state gates), #8682 (desktop E2E composer + row actions). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-30 10:00:00 +11:00

Luke Tornquist	1f16f621d8	perf(relay): cut connect-burst CPU in log filtering and open-channel lookup (#8670) ... ## Summary A cold relay taking a burst of new connections spent most of its CPU on two things that don't scale with useful work. This PR removes both. **Log filtering held a contended lock.** `EnvFilter` (tracing-subscriber 0.3.23) takes a shared `RwLock` read on every span enter and exit, even when no directive names a span. Every poll of an instrumented future enters its span, and the relay installs two per-layer `EnvFilter`s (logs and OTEL), so every worker contends on those locks. Plain `target=level` directive lists now filter through `tracing_subscriber::filter::Targets`, which keeps no per-span state. Directives that name spans or fields still use `EnvFilter`, which is the only filter that understands them. **Each reader re-read the community's open channels.** A reader's accessible channels are its member channels plus the community's listed open channels, and the open half is the same for every reader. The per-reader cache stored the union, so every miss fetched every open channel row again. The lookup is now two cached halves: - member channels, per reader, cached as before; - open channels, once per community. The shared half is used for a bounded time. Cross-pod invalidation is best-effort, so a pod can miss the drop that follows a channel becoming private, unlisted or deleted elsewhere. Each cached open set records when its database read began, and readers use it only for `OPEN_CHANNELS_MAX_AGE` (1 s) after that. After that the next reader re-reads it. **Accepted trade-off:** if an invalidation is lost, any reader on that pod can be granted a just-revoked open channel, history included, for at most 1 s. That includes a reader with no cache entry, which on `main` always read the database. This is a new exposure for those readers. With no bound, the shared set could have served that channel for its 10 s TTL. Readers with a cached entry already had a 10 s window on `main`, so for them the bound is tighter than before. An exact per-community version check would remove the window but needs a schema change, so it's tracked as a follow-up. Invalidations still drop the halves. A community-wide accessible-channel or channel-deleted invalidation drops both halves, and a membership invalidation drops only that reader's member half. The age bound counts from the start of the read, so open-set fills need no fence: a fill that raced a drop is still at most 1 s stale. Uncached callers of `get_accessible_channel_ids` get the same set as before, now built from the two halves. Open-set reads are counted by `buzz_open_channels_cache_hits_total` and `buzz_open_channels_cache_misses_total{reason="absent"|"expired"}`. **Metric meaning change:** `buzz_accessible_channels_cache_hits_total` and `buzz_accessible_channels_cache_misses_total` keep their names but now count only the per-reader member half. Dashboards that read them as whole-lookup hit rates should add the open-set counters above. Empty levels (`target=`) stay on `EnvFilter`. `Targets` reads an empty level as ERROR while `EnvFilter` reads it as TRACE, so only `target=level` directives with a non-empty level take the `Targets` path. ## Results Measured with the relay load generator (#8636) on one Linux machine. The relay ran as a release build on 8 pinned cores, with local Postgres, Redis and MinIO; the generator ran on separate cores. The fixture is one community with 2,000 open channels. Clients connect in a burst against a cold relay: 48k WebSocket clients and 4.8k HTTP agents. Each arm restored the same database snapshot and ran the same generator binary and scenario. Arms were rotated (base/before/after, then before/after/base, then after/base/before), and the table shows medians of three runs per arm. Both columns after base also carry #8666, so the comparison isolates this PR's design. - **before** is this PR's first revision, which had an unbounded shared open set. - **after** is this head, where the open set is bounded to 1 s. | | base | before | after | |---|---|---|---| | relay cores (mean) | 6.37 | 2.39 | 2.45 | | connect p99 | 3,870 ms | 40 ms | 42 ms | | subscribe EOSE p99 | 12,952 ms | 110 ms | 112 ms | | history EOSE p99 | 1,252 ms | 68 ms | 72 ms | | live delivery p99 | 26,421 ms | 54 ms | 55 ms | | HTTP query p99 | 16,426 ms | 44 ms | 43 ms | | DB tuples returned/s | 1.04M | 43k | 49k | | DB transactions/s | 4,397 | 4,065 | 4,062 | | relay RSS peak | 12.6 GB | 10.7 GB | 10.7 GB | | errors | 16, plus 241k throttled | 0 | 0 | The 1 s bound costs about 1,400 extra open-set reads per run, within run-to-run noise of the unbounded version. One run in each of the two right-hand arms had a slow tail (connect p99 0.8–1.3 s), which the medians absorb. An earlier revision bound the shared set to a per-reader digest instead. That was exact, but in the same kind of A/B its per-miss digest query returned about 28 times the tuples per second of the unbounded version. It gave back the database savings, so this revision uses the time bound. The open-channel gain scales with how many listed open channels a community has. The filter gain doesn't depend on the fixture. ## Rollout There's no flag, so the change takes effect on deploy. There's no schema or data change, so reverting the commit is the rollback. 1. Deploy to staging and compare relay CPU and connect and EOSE p99 under a connection burst. 2. Watch `buzz_open_channels_cache_misses_total{reason="expired"}`. Expect at most about one per second per active community per pod. 3. Confirm the deployed `RUST_LOG` and `BUZZ_OTEL_FILTER` are plain `target=level` lists, so they take the `Targets` path. Other values fall back to `EnvFilter` and keep today's cost. ## What got simpler - `invalidate_channel_deleted_local` now reuses the community-scoped accessible-channel drop instead of repeating it. - Tests seed accessible channels through one `seed_accessible_channels` helper instead of writing cache internals. ## Tests - `telemetry::tests::only_plain_target_level_directives_use_targets` checks which directive strings are plain. It covers span directives, field directives, whitespace, empty segments, empty targets (`=debug`) and bad levels. - The rewritten `env_filter_tests` assert on captured log output rather than `Display` strings or cached callsite interest, so they are stable when run in parallel. `span_directives_keep_env_filter_semantics` proves that `[conn]=debug` still enables events only inside the span. - `state::tests::postgres_tests::a_lost_open_set_invalidation_grants_a_revoked_channel_only_until_max_age` runs two relay states on one database, with no pub/sub between them. For each revocation (private, deleted, unlisted), it: 1. primes the reader pod; 2. revokes the channel in SQL and invalidates only the writer pod; 3. shows that a new reader is still granted the channel within the window; 4. ages the cached set past the limit; 5. asserts that a new reader and an earlier cached reader are both denied. Dropping the age check fails it. Never caching the open set fails its within-window control. - `env_filter_tests::directive_filters_log_what_env_filter_logs` emits events at every level for six targets, including prefix lookalikes. It asserts that the filter built for each of 17 directive lists logs exactly what `EnvFilter` logs for that list. Routing `buzz_relay=` to `Targets` fails it. - `state::tests::accessible_channels_join_member_and_open_halves` checks the merge. The two existing scoped-invalidation tests now also assert the open half. - These state tests, and the two existing ones, were not in the `just test-unit` allowlist. They are infra-free, so they are now selected by exact name, and `scripts/run-tests.sh` mirrors that. Identified debt, not fixed here: the per-reader member half keeps the pre-existing unfenced read-then-insert (a raced fill only reaches that reader, as before). `handlers::req::tests::expiry_during_stalled_{history,search}_read_releases_permit_and_claim` are not selected by any CI lane. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-29 21:59:17 +00:00
Brad Seiler	1fe120165f	BUZZ-272: Deny workflow runs for banned owners (#8242) ... ## Summary A workflow whose saved owner is banned from the community can no longer create runs through any trigger: webhook, channel-event, cron, or signed command trigger. Every one of those doors already calls `WorkflowEngine::check_owner_authority`, which re-checks the owner's channel role. That gate now also reads the owner's authoritative restriction state. A ban denies the run, and a failed lookup fails closed. Unbanning restores admission. On the webhook door the denial is the same generic 404 as before, and no run is queued. On the event and cron paths, a ban denial is logged at WARN at most once per workflow every ten minutes, and at DEBUG in between. A failed lookup and every other denial still warn every time. The handler-local ban lookup in `api/bridge.rs` is removed because the shared gate covers it. This is a point-in-time check: a ban committed after the lookup can race with run creation. It does not cancel existing runs. Community timeouts do not block runs in this change. This PR also carries the shared mesh receive fix needed for independent validation (see Shared carry). ### Related BUZZ-272. - Invitations: [#8237](https://github.com/block/buzz/pull/8237). - Route coverage: [#8239](https://github.com/block/buzz/pull/8239). - Live-session revalidation: [#8241](https://github.com/block/buzz/pull/8241). - Staging runbook: [#8235](https://github.com/block/buzz/pull/8235). ### Testing Postgres lane: - `on_event_denies_run_while_owner_banned`: a banned owner's channel-event trigger creates no run, and after unban it creates one. - `cron_tick_skips_banned_owners_without_consuming_the_claim`: one tick skips a banned owner and an agent whose human owner is banned, while an unbanned workflow on the same tick still fires. After unban, a tick for the same scheduled instant fires both, so the denial did not consume their scheduled-fire claim. - `on_event_denies_run_when_restriction_lookup_fails`: the event path fails closed when the restriction read errors, and fires once the read succeeds. - `webhook_admission_enforces_owner_ban_tenant_scope_and_lookup_failure`: the HTTP door returns the same generic 404 for a wrong secret, a banned owner, a forbidden role and a failed restriction lookup, with no run created. It also covers another tenant's allowed control and unban. Unit lane: - `ban_denial_warns_once_per_interval_while_other_denials_always_warn`. Results: - At `81c367f48`, CI passed: Unit Tests 572/572, PostgreSQL Tests 1169/1169 and Relay E2E. A local-relay E2E also passed: - unbanned webhook: 202 and one run; - banned webhook: generic 404 and no run; - banned event trigger: no run; - after unban: one run. - At `72c8d8bbc` (merged with main), CI passed: Unit Tests (including all 171 buzz-workflow unit tests), PostgreSQL Tests 1227/1227 (all four ban tests listed by name), and both `Build (linux/amd64|arm64)` image jobs, which build with `--locked`. A Blox run at the same head also passed `cargo metadata --locked`, fmt and clippy, and the buzz-workflow unit tests passed there with no database reachable. - Not covered: the signed trigger has no dedicated test. It calls the same gate, which was confirmed by reading the code. ### Shared carry #8237, #8239, #8241 and #8242 each carry the same mesh-receive fix, boot and scraper regressions, and push-lease fixture correction. Whichever lands first owns them, and the others drop them on their next main merge. ### What got simpler The ban check now lives in the one gate every run-creation door already shares, so there is one fewer handler-local branch. Cron, event and signed triggers get the same protection without per-door code. The cron loop body is now `cron_tick(now)`, so a test can drive one tick without the 60-second sleep. buzz-workflow's infra-free unit tests ran in no CI lane. `just test-unit` and its cargo fallback in `scripts/run-tests.sh` now run them. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: seiler <seiler@squareup.com> Signed-off-by: Brad Seiler <seiler@squareup.com> Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Codex <noreply@openai.com> Co-authored-by: Codex <codex@openai.com> Co-authored-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-29 17:27:24 -04:00
Luke Tornquist	aed4be8592	Add a scenario-driven relay load generator (#8636) ... ## Summary Buzz has no way to load-test the relay as a whole. `wamp_bench` sends kind:9 messages from one identity to one channel, and `perf/relay_bus_scaling.py` only measures Redis fan-out. Neither can show what happens to a relay with many more users, channels, or deep threads. This PR adds `buzz-loadgen`, a load generator in `crates/buzz-test-client`: - `buzz-loadgen seed <scenario.toml>` creates communities (through `POST /operator/communities`), channels, channel history, and deep threads. - `buzz-loadgen run <scenario.toml>` drives simulated humans and agents through ramp steps (1x, 2x, ...) and prints p50/p90/p99 latency, errors, and rate-limit rejections per operation for each step. - Humans hold a WebSocket with live subscriptions, fetch history on connect, and send presence, typing, messages, thread replies, and reactions. Agents authenticate with a NIP-OA tag, poll HTTP `/query`, post through HTTP `/events`, and send encrypted observer frames to their owner. - Per-client rates come from the scenario. Set them to model a deployment, and a step of `users = 10` means 10x that deployment's population. - Every identity, host, and channel id comes from the scenario's `run_id`, so `--shard i/n` splits a population across machines with no coordination. - Each step measures from ramp start to hold end, so connect failures during the ramp count. A step aborts the run when an operation's error rate or p99 (delivery included) crosses the scenario's `[abort]` limits, when a relay `CLOSED`s a live subscription often enough, or when a client exits unexpectedly. The report names the limit that tripped. - Each connect plus authentication has a deadline (`target.connect_timeout_secs`), and shutdown is bounded, so a relay that stalls connections still produces a report and a non-zero exit. - `seed` exits non-zero unless the relay accepted every planned post. - `NostrWsConnection::connect_to_addr` opens the TCP connection to a given address while the URL still names the host. This lets a client inside the relay's cluster reach a community host through the relay's service address. - `wamp_bench` is deleted. Its paced single-channel load is a subset of a scenario. What got simpler: one load tool instead of two partial ones. The change touches only test tooling, the unit-test lane, and one additive method in `buzz-ws-client`. Relay code is unchanged. ### Related issue None found. ### Testing Smoke run on a Linux workstation against a local relay built from this branch, with its own Postgres, Redis, and MinIO containers: ```bash cargo run --release -p buzz-test-client --bin buzz-loadgen -- seed perf/scenarios/local-smoke.toml cargo run --release -p buzz-test-client --bin buzz-loadgen -- run perf/scenarios/local-smoke.toml ``` - `seed`: 710 of 710 posts accepted (10 channels, 200 history messages, 10 thread roots, 500 thread replies). - `run`: both steps (1x = 50 humans + 5 agents, then 2x) completed with 0 errors and 0 rate-limit rejections. Every operation recorded traffic: 55/55 connect/auth, 205/205 live subscriptions, 150 history fetches, presence/typing/observer frames, messages and reactions, HTTP `/query`, HTTP `/events`, and publish→delivery. Delivery p99 was 45 ms at 1x and 42 ms at 2x. - Failure paths are covered by unit tests: a listener that accepts TCP but never answers (connect deadline, then `run` aborts and returns), a fake `/events` server that rejects posts (`seed` fails), `CLOSED` subscriptions, and invalid scenarios. `just test-unit` (and its `scripts/run-tests.sh` fallback) now runs the new `loadgen::` unit tests.

klopez4212	39b8b2b6a6	feat(mobile): unify Messages navigation with Solo and Team filters (#8649) ... ## Summary Unify mobile conversations in Messages with All / Solo / Team filters, a collapsing header, and separate Search, New, and default-agent shortcuts. Move workspace actions into the community menu and keep collapsed sections intact across filters. Align Inbox and list typography, spacing, and muted controls. Preserve native glass layering through navigation and give every filtered list enough clearance above the footer. The default-agent shortcut reads the shared encrypted preference and opens an existing chat immediately. When unset, it opens Agents; a star action selects the default through a production signed, self-encrypted preference writer. Save failures remain visible and retryable. Android now uses rounded navigation controls and filters, optically balanced search icons, and expanding New/community menus with leading Tabler icons matching iOS. Preset avatars retain transparent WebM animation through an Android WebView renderer, with lifecycle pausing and poster fallback. ### Related issue None found in searches for mobile navigation issues and open PRs. ### Testing - Android follow-up: ARM64 debug build, Dart analysis, and emulator checks passed for menu placement, selection, icon alignment, search, and avatar playback/pause/resume. The avatar implementation passed 3,840 Flutter tests and native Android tests before subsequent styling iterations. Automated tests for the later menu/icon iterations were skipped at the author’s request; those earlier results do not cover the final styling changes. - Mobile formatting/analysis and full test suite (3,838 passed, 23 skipped, plus 4 push-configuration tests); regression journey covers filtering, collapse retention, and scrolling the last Solo row above the footer. - iPhone 18 Pro simulator (Honeycomb): filters, menus, Inbox, Invite/Back, Switch Community, and default-agent chat/Back exercised. iOS release build and Pairing Preview install/launch passed during iteration, preserving the saved profile. - P1 follow-up: production writer-to-reader widget journey covers selection, publish failure/retry, and the unset footer opening Agents. Simulator Agents open/close passes; its saved community has no selectable agents, so live selection was not verified there. - Independent agent review completed; its Solo footer-clearance finding is fixed. The final clearance adjustment is covered by widget tests; physical-device acceptance of that adjustment and hosted CI remain pending.

Matt Toohey	eda26b9423	ci: repeat changed tests ten times on pull requests (#8613) ... This ports the advisory flake check from block/buzz-app (https://github.com/block/buzz-app/pull/890) to this repository: pull requests repeat the tests they change ten times, with retries off, so a test that passes CI by luck is caught before it merges. ## What it does `flake-select` diffs the PR merge commit against its first parent (`HEAD^1..HEAD`, `fetch-depth: 2`) and maps changed hunks to tests per runner: a hunk inside a test body selects that test; a change anywhere else in a test file, or a new file, selects the whole file. One lane per runner then repeats only that selection 10× with retries disabled and writes a test × iteration table to its step summary. Lanes skip when nothing was selected, run only on `pull_request`, and are not read by any required gate in `ci.yml` — their own statuses carry the result. ## Per runner | Runner | Selection granularity | Repeat mechanism | |---|---|---| | Rust (cargo-nextest) | `crates/<crate>/<path>.rs::<module::test>` from `#[test]`-style attribute spans (comments and literals blanked first). A hunk outside any test body selects the file's tests. `#[ignore]`d and Postgres / `external_infra` tests are excluded. | One `cargo nextest run --profile flake` per package per iteration, with target flags derived from the path (`src/**` → `--lib --bins`, `tests/<stem>.rs` → `--test <stem>`), a filterset of exact `binary_id & test` pairs, and JUnit parsed per iteration. New `[profile.flake]`: `retries = 0`, `fail-fast = false`. | | node:test | Whole changed `desktop/src/**/*.test.mjs`, `*.jsdom-test.mjs`, `desktop/scripts/*.test.mjs` | 10× loop, each file alone, with the flag sets from `desktop/package.json` `test` | | Playwright `smoke` | `file:line` journeys from `test()`/`it()` spans (TypeScript AST) intersected with `playwright test --list --project=smoke`, deduplicated | Native `--repeat-each=10 --retries=0`, sharded `min(10, ceil(journeys / 5))` ways; `playwright-summary` tabulates the JSON report | | Flutter | Whole changed `mobile/test/**/*_test.dart` | 10× `flutter test --file-reporter=json` loop with the mobile lane's `--dart-define` | A runner whose selection exceeds 64 KiB of entries, or more than 250 Playwright journeys, is skipped with a note rather than overrunning its timeout. ## Differences from the buzz-app version - Lanes live in a reusable `_ci-flake.yml` called from `ci.yml`, matching this repo's `_ci-*.yml` convention, instead of inline jobs. - Playwright specs are parsed with the desktop app's own `typescript` package rather than `rolldown/parseAst`. - No Playwright `integration` project lane: it needs the relay artifact chain. Integration-only specs list nothing for `smoke` and the selection stays empty. - Playwright shards are capped at 10, the same bound as the regular smoke lane. - Rust entries carry the file and in-file module path, and the filterset is anchored to exact `(binary, test)` pairs, so a same-named test in another module is not repeated. - nextest target flags are derived from the changed file's path, so a `buzz-relay` change does not compile every test target of the crate. - A journey-count cap (250) skips the Playwright lane for selections ten repetitions could not finish within its 45-minute timeout. ## Heads-up - The Unit Tests `rust-cache` moves from `key: sherpa-cache-v1` to `shared-key: unit-tests-sherpa-cache-v1` so the flake lane can restore it read-only. This changes the cache key once: the first Unit Tests run after merge builds cold. - This PR itself changes no file the selector recognises (`scripts/flake-check.test.mjs` is a root script, run by the Desktop lane), so its own Flake Check lanes are expected to skip. ## Verification - `node --test scripts/flake-check.test.mjs` — all unit tests pass (also wired into the Desktop lane). - `actionlint` on the changed workflows; `biome check` on the two scripts. - `scripts/test-rust-cache-contract.sh` and its regression harness pass with the new shared key. - Synthetic-diff selection runs for each runner, plus `select` against this PR's own merge-base (empty, as expected). - 2-iteration repeats of a real selection on all four runners locally. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com>	2026-10-29 14:34:20 +11:00

Luke Tornquist	0a362eef15	perf(db,relay): bound thread participant scans and coalesce live summaries (#8635) ... ## Summary A thread summary's `participants` (up to 10 recent authors, used for the facepile) was computed by aggregating **every** reply in the thread. The live `kind:39005` emit runs that aggregate on the writer after every reply insert and every threaded delete. Each summary therefore cost O(thread), recomputed after every reply, so one very large thread could saturate the writer. ### Scale and impact A single long-running thread can grow to hundreds of thousands of replies and take several new replies per second. Each of those replies then pays a whole-thread aggregate on the writer, so writer CPU follows the reply rate of the largest active threads, and the read-side participant queries (channel window, thread root summaries) slow down the same way. Synthetic reproduction (PostgreSQL 17, the repo's `schema/schema.sql`, default `shared_buffers`): one channel with 200k background messages and three threads of 450k, 6k and 300 replies from a few authors with ~800-byte bodies. `EXPLAIN (ANALYZE, BUFFERS)` of the participant query, warm cache (runs 2–3 of 3): | Thread | Before (whole-thread aggregate) | After (newest 1000 replies) | |---|---|---| | 450k replies | ~7.6 s, ~117k buffers read, ~16k temp blocks spilled | ~6.8 ms, ~4k buffers | | 6k replies | ~25 ms, ~24k buffers | ~7 ms, ~4k buffers | | 300 replies | ~2.6 ms, ~1.2k buffers | ~2.6 ms, ~1.2k buffers | Cost now stops growing at 1000 replies, and small threads cost the same as before. With coalescing, a busy thread runs this query at most about once per second per pod instead of once per reply. ### Change 1. **Bound the participant scan to the newest 1000 replies.** All three participant readers now share one SQL fragment (`recent_thread_participants_sql!`): - `get_thread_summary` (the live 39005 emit) - the channel-window batch - `resolve_thread_root_summaries` The fragment walks `idx_thread_metadata_window` newest-first with `LIMIT 1000`, then joins `events` only for those rows, to get `pubkey` and drop deleted replies. Deleted replies keep their `thread_metadata` row, so they count toward the 1000 but contribute no author. It aggregates by author and returns the 10 most recently active. Cost no longer grows with thread size. Desktop and mobile show the 3 most recent participants and the forum view shows up to 10, so an author who hasn't posted in the last 1000 replies is not visible in any client today. `NIP-CW`, `docs/bridge-channel-window.md` and the `ThreadSummary::participants` doc now state the bound, deleted replies included. 2. **Coalesce live summary emits per thread root.** `emit_live_thread_summary` goes through a new `CoalescedRefresh` keyed by `(community, root)`: - A quiet thread emits immediately, as before. - On a busy thread, emits are spaced at least 1s apart per pod. A trailing emit covers the rest of the burst and reads state committed after its last mutation. - Because emits are at least 1s apart, consecutive overlays from one pod always get strictly increasing `created_at`, so the client's newest-wins replacement is never tied. - A panicking or cancelled refresh releases its key, including a task dropped before its first poll: the release guard is built before the spawn. Each run is bounded by a 30s timeout so a hung refresh can't wedge it. ### What got simpler - Three hand-written copies of the participant aggregate are now one fragment. - `get_thread_summary` is one statement instead of two round trips. - The channel-window batch dropped its `ROW_NUMBER()` window function and the `GROUP BY root, pubkey` over every reply of every root on the page. ### Related issue None found. ### Testing - `participant_summaries_read_only_the_newest_replies` (buzz-db, Postgres) seeds a thread with 1001 replies: - an early author, pushed just outside the window - a filler author - a deleted reply - a latest author All three readers must return `[latest, filler]`. Mutant check: removing the `LIMIT` (whole-thread aggregate) turns it red. - `coalesced_refresh` unit tests (paused tokio clock): - A 100-request burst runs once immediately and once trailing, then frees the key. - Separate keys run independently. - A panicking refresh doesn't wedge its key. - A hung refresh times out and releases its key. Mutant check: removing the timeout turns it red. - A request that arrives while a run is in flight gets one trailing run, and that run reads the state written mid-run. Mutant check: dropping the rerun flag turns it red. - A task dropped before its first poll (runtime shut down) still releases its key. Mutant check: building the guard inside the task turns it red. These run in `just test-unit` (added to the buzz-relay `--lib` filter and `scripts/run-tests.sh`). - Blox gate: `cargo fmt --check`, clippy `-D warnings` (buzz-db, buzz-relay), and the full buzz-db and buzz-relay Postgres nextest lanes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-28 15:59:19 -04:00
Will Pfleger	369ffa0380	feat(relay): verify NIP-FI agent tokens and admit agents through owners (#8401) ... The relay side of NIP-FI agent tokens. An agent token has its own type, `nip-fi-agent+jwt`, and carries its human owner's pubkey in `nostr_owner_pubkey`. This PR verifies that claim, makes denying or disconnecting the owner cut off every agent that owner authorized, and makes the verified owner decide community admission. A relay without agent support refuses the unknown type, so nothing needs to advertise or configure agent support. The `NIP-FI.md` text for the agent type is included. Builds on #8372 and #8377 (both merged). ### Owner claim and owner deny - **Token type binds the owner claim (`buzz-auth`).** A `DedicatedNipFi` issuer policy accepts `nip-fi+jwt` (human) and `nip-fi-agent+jwt` (agent); `AccessTokenAtJwt` policies stay `at+jwt`-only with their `client_id` and subject rules unchanged, and unknown types are refused. An agent token must carry a lowercase-hex `nostr_owner_pubkey` distinct from its `nostr_pubkey`; a human or `at+jwt` token carrying the claim with any value, including null, is `evidence_rejected`. The verified owner is exposed as `VerifiedAssertion::owner()`. - **No agent switch.** There is no relay setting, NIP-11 field or operator binding field for agent support. - **Session owner.** Each connection records its NIP-FI issuer and the agent's owner (`NipFiSession`) on the root WebSocket manager and the audio registry. `disconnect_nip_fi(iss, target)` closes a connection when either its own key or its recorded owner equals the target. - **Owner deny check.** `nip_fi_core::assertion_denied` checks the deny set for both `(iss, k)` and `(iss, owner)`, and every existing deny check uses it: WebSocket before upgrade and after registration, HTTP, audio, and the shadow observer, so shadow and enforce make the same decisions. The shadow disconnect observer matches a session's key or owner under its issuer with the same rule, so an owner's disconnect records a would-close for its agents. ### Shadow owner check In shadow mode, WebSocket AUTH, audio join and HTTP admission record a `Stage::Owner` verdict when an admitted agent token's owner is banned (`owner/denied`), conflicts with the agent's stored owner (`owner/denied`), or cannot be checked because a read failed (`owner/unavailable`). These are reads only; shadow admission is unchanged. Shadow applies the same stored-owner rule as enforce but never writes the link, so it can't predict a later owner-link write failure, or which of two racing first links wins. ### Admission through the verified owner - **Owner bans, unconditionally.** `community_ban_outcome` takes the token owner and checks its ban in place of a NIP-OA owner. That applies whether the agent is a member itself, the relay is open, or the agent is admitted through its owner. - **Owner-derived membership.** In `api::relay_members::check_membership`, an agent that is a member itself is still admitted first. Otherwise, when a verified assertion names an owner, the owner's membership decides (`MembershipDecision::ViaOwner`), and no NIP-OA is needed on the connection. The issuer has already passed this community's NIP-FI binding check at that point. When a token owner is present it is the only owner considered. - **Stored-owner consistency.** `link_agent_owner` replaces the boolean `materialize_nip_oa_owner` result with `OwnerLink::{Linked, Conflict, Unavailable}`. An unset stored owner is recorded, so relay bans and roster removal of the owner reach the agent through `revoke_live_access`. Shadow and enforce judge the stored owner through one read, `stored_owner_link`, and `link_agent_owner` writes (atomically, first write wins) only when that read finds no owner; a failed read fails closed. If the stored owner differs from the token owner, the request is refused with `authorization denied` on HTTP, WS and audio. A NIP-OA owner conflict keeps its existing link-error refusal. - **One decision on every surface.** Root WS AUTH, audio registration and every NIP-98 HTTP route (bridge, `buzz/v1`, git transport and settings, invites, media, workflows, moderation reads) pass `NipFiAdmission::token_owner()` / `VerifiedAssertion::owner()` into the same ban, membership and owner-link steps. The final socket check rereads bans and writer-side membership; it doesn't reread the owner link, which is written once from NULL. HTTP membership still goes through the bounded replica read. With a verified agent token, every HTTP admission refusal, including the fresh ban rereads in `buzz/v1` and Git settings, is NIP-FI's fixed `authorization_denied` (or `authorization_unavailable` when a dependency fails), and audio checks bans before writing the owner link. `enforce_relay_membership` now takes the `TenantContext`, because it writes the owner link. - **Publishing.** A ban caught while publishing over `POST /events` after the shared membership check is also an admission refusal. Ingest reports it as a typed `IngestError::Ban` (banned, or ban lookup unavailable) at the write gate, the HTTP typing indicator's cached gate, and the moderation and relay-admin command rereads. `IngestError::Ban` carries the legacy error. The bridge turns it into the fixed `authorization denied` / `authorization unavailable` only when the request carries a verified agent token. WebSocket and token-less HTTP responses are byte-for-byte unchanged, and timeouts, scopes, permissions and every other ingest error keep their existing responses. ### Rollout - **Deploy the relay before kgoose.** An older relay refuses `nip-fi-agent+jwt`, so agents are locked out until both are deployed. Humans are unaffected. - **There is no agent-only switch.** Setting NIP-FI to shadow or off turns it off for humans too. - **Rollback is safe for owner links.** Stored owner links survive a rollback, and the older code still honors them. - **Shadow signals:** in `buzz_nip_fi_shadow_total`, `stage="owner"` means an owner would-deny (`owner/denied`) or an owner read that was unavailable (`owner/unavailable`), not a success. A clean agent admission shows as `stage="admit", outcome="admit"`. - **The relay checks that the owner is a member, not which issuer the owner logged in through.** In a community that trusts several issuers, any trusted issuer can name any member as owner. That matches the spec: the issuer is trusted to vouch for the owner, and kgoose requires the owner's attestation. Agent tokens are only issued to relays whose NIP-FI binding trusts the issuer, and NIP-FI itself is off unless configured. No deployed config or secrets change. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-26 12:48:35 -04:00
Luke Tornquist	7ce422417b	fix(mesh): expire dead peer records and instrument mesh boot (#8503) ... ## Summary Relay pods can stall in the `mesh_boot` startup step, and the mesh peer table grows without limit. One prod pod held 7,793 peer records. Most of those records belong to pods that no longer exist. **Cause.** Every boot gets a fresh runtime id, so a restarted pod leaves its old record behind. Nothing ever removed records, and scuttlebutt gossip kept spreading the dead ones around the fleet. Each reconcile pass, including the first one inside `boot_mesh`, then dials every record one at a time. This PR makes dead records expire. It also adds the measurements we need to see the next stall directly. ### Peer-table lifetime (`crates/buzz-relay-mesh/src/membership.rs`) - A peer record expires 5 minutes after its last heartbeat (`DEFAULT_PEER_RECORD_TTL`). For comparison, live runtimes refresh every 2s, and the Redis ready registry expires a silent runtime after 45s. - What happens to expired records: - They are **rejected on arrival**, so peers that haven't been upgraded can't re-add them. - They are **left out** of digests, deltas, and dial candidates. - They are **pruned** at the start of each reconcile pass. - Between prunes, they are not admitted (`has_peer`) and not routed (`peers`, `peer_has_capability`). - An expired entry that hasn't been pruned yet counts as absent, so any fresh record replaces it whatever its version. That lets a live peer's v1 Redis hint re-admit it before the next prune. - **The TTL never prunes or hides a peer with a live connection**, even if its heartbeat is stale. Its gossip can stop arriving while the transport stays up: a dead control stream, or a clock behind by more than the TTL. The connection proves the runtime is alive. Its stale record is still kept out of digests and dials. (The existing phi filter in `peers()` still drops a connected peer once its gossip stalls; this PR doesn't change that.) - **`Connected` tracks the transport map.** Because the TTL exemption trusts that flag, `install_peer` and `remove_peer` write it while holding the peers lock, so a connection that closes during install always ends `Disconnected`. A dial's `Connecting`/`Disconnected` writes are skipped when a connection is already installed, so a failed outbound dial can't overwrite a live inbound connection. Each reconcile pass also re-syncs the state from the transport map. - **Gossip no longer sets connection state.** Before, any gossiped record was marked `Connected`, even if this pod had never dialed it. That inflated the `/_mesh` counts. Now a record learned from gossip or the ready registry enters as `Disconnected`. Only the real connect and disconnect paths change the state. - Before building its candidate list, reconcile now skips peers that are already connected. A pass dials serially, and a dial to a dead runtime can take about a minute, so `dial_peer` re-reads the record before every address attempt. It stops once the record has expired or started draining, or once a connection has landed. ### Instrumentation - **`mesh_boot` sub-steps** use the existing startup-step gauges: `mesh_bind`, `mesh_publish`, and `mesh_initial_reconcile`. A pod stuck in `mesh_boot` now also shows which await it is stuck on. - **New metrics** (`crates/buzz-relay-mesh/src/telemetry.rs`): | Metric | Shows | |---|---| | `buzz_mesh_dial_total{outcome}` / `buzz_mesh_dial_duration_seconds` | Cost of each dial | | `buzz_mesh_reconcile_pass_seconds` | Full pass time | | `buzz_mesh_reconcile_candidates` | Dials planned for this pass (set after the registry scan) | | `buzz_mesh_peer_records{state,draining}` | Table size | | `buzz_mesh_peer_record_max_age_seconds` | Oldest heartbeat | | `buzz_mesh_peer_records_expired_total{reason=pruned\|rejected}` | Expiry activity | - The dial and pass histograms get buckets up to 600s. The default `_seconds` buckets stop at 5s, which would hide exactly the stall these metrics are meant to show. ### CI The `buzz-relay-mesh` tests and the `buzz-relay` `mesh_boot::tests` did not run in any CI lane. This PR adds both to `just test-unit`, and adds the matching stanzas to `scripts/run-tests.sh`. ### What got simpler - The peer table now has a defined size, about one record per live pod, where before it grew forever. - One wrong state write was deleted (gossip marking records `Connected`). - Two test suites that silently never ran now run. ### Rollout notes - Rejecting expired records works one pod at a time. During a rollout, pods that haven't been upgraded keep gossiping dead records. Upgraded pods reject them, which shows up as `reason="rejected"` on the expired counter. - A pod whose clock runs more than 5 minutes behind has all of its gossip rejected. It stays reachable through its Redis ready record and any live connection. A `reason="rejected"` count that keeps climbing outside a rollout points to that skew. - Upgraded pods leave expired records out of their digests. Pods that haven't been upgraded therefore resend the whole ghost set (about 7.8k records, roughly 1 MB) on every 2s gossip tick, on each old↔new connection. So during the rollout, `reason="rejected"` will climb by about the ghost count per tick per connection. This is expected and stops when the rollout finishes. ### Not in this PR The boot dial itself is still unbounded: it runs serially, has no per-dial timeout, and dials gossip-learned records. Bounding it changes how a pod joins the mesh, so it goes in a separate PR, and these metrics will measure it. ### Related issue None found. ### Testing - New tests: - `membership::tests`: expired gossip is rejected; prune drops only expired records; prune keeps a connected peer with a stale heartbeat; expired unconnected records are neither admitted nor routed before a prune; a fresh record replaces an expired, unpruned entry whatever its version; expired records are neither dialed nor gossiped before a prune; gossip never sets connection state; table stats. - `runtime::tests::reconcile_pass_publishes_dial_and_peer_table_metrics` - `runtime::tests::reconcile_pass_prunes_expired_peer_records` (binds the prune to the reconcile pass) - `runtime::tests::dial_skips_candidate_that_expired_after_the_pass_snapshot` - `runtime::tests::finishing_dial_does_not_overwrite_a_connection_that_landed` - `runtime::tests::connection_closed_during_install_ends_disconnected_and_expires` - `runtime::tests::reconcile_pass_resyncs_connection_state_from_transport` - `mesh_boot::tests::mesh_boot_sub_steps_name_the_step_that_failed` - Blox at `e06f55a4` (tree `866add1c`): `just fmt-check`, `just clippy`, `buzz-relay-mesh` nextest 3x, and the `buzz-relay` `mesh_boot`/`startup_steps`/`metrics` tests all pass. Three of the new tests fail against a mutant that removes the fix they pin (dial ignores expiry; dial state writes ignore the transport map; no reconcile resync). --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-26 09:47:30 -04:00
Ian Oberst	20ba95ed89	fix(db): rebuild events_pkey in declared order after pgschema apply (#8525) ... ## Summary Re-applying `schema/schema.sql` to a database that `pgschema apply` and `scripts/reconcile-schema-after-pgschema.sql` already bootstrapped fails with `cannot drop inherited constraint "events_p2026_01_pkey" of relation "events_p2026_01" (SQLSTATE 42P16)`. Because of that, `scripts/start-relay-for-tests.sh` breaks against a reused database. **Cause:** pgschema 1.7.4 moves a partitioned table's partition key to the front of its primary key when it creates the table. A pgschema-bootstrapped `events` therefore gets `PRIMARY KEY (created_at, community_id, id)`. `schema/tables/public/events.sql` and `migrations/0001` both declare `(community_id, created_at, id)`. Every later plan drops and re-adds `events_pkey` and each declared child's key. This happens even on a database that was never reconciled. The plan only becomes unexecutable after the reconcile script attaches the children, because their keys are then inherited. As a side effect, pgschema-bootstrapped databases also had a differently ordered PK index than migration-managed ones. **Fix:** after the partition ATTACH block, the reconcile script now compares `events_pkey` with the declared `PRIMARY KEY (community_id, created_at, id)`. If they differ, it rebuilds the key on the parent. It then asserts that `events` and every partition carry the declared key, which is the "convergence plus live assertion" shape `docs/database.md` requires. PostgreSQL recreates each partition's key with the same `<child>_pkey` names, so a reconciled re-apply now plans nothing. The block does nothing when the key is already correct. `migrations/0001` is untouched. Only pgschema-bootstrapped dev and test databases run this script, so it does not touch the out-of-band partitioned-table procedure. `delivery_log` is not affected. Its key `(delivered_at, id)` already starts with the partition key. **Existing local databases:** a database reconciled before this change would still fail its next `pgschema apply`, because the reconcile script only runs after apply. The repair therefore also lives in `scripts/repair-events-pkey.sql`. That file does nothing when `events` doesn't exist yet, and `scripts/start-relay-for-tests.sh` runs it before apply; it's the only launcher that reuses its database. The reconcile script keeps a verbatim copy for fresh bootstraps, and a unit test keeps the two identical. The rebuild drops the key with `IF EXISTS`, so a database that has lost its key still converges. It also takes its locks with a 10s `lock_timeout`. If a relay still holds `events`, it fails with "Stop any relay using this database, then rerun" instead of hanging. `start-relay-for-tests.sh` now builds the relay's `DATABASE_URL` from the `PG*` variables it already exports. The secret scanner flags the literal URI once the file is touched. The value is unchanged. pgschema 1.13.3 keeps the declared order and creates children as native `PARTITION OF`. Upgrading would make this block and the ATTACH blocks unnecessary, but it changes behavior for every caller, so it is left for a separate change. ### Related issue Follow-up to block/buzz#8487, which added the probe test and `.pgschemaignore`. Now rebased onto `main` after that PR merged. ### Testing - `pgschema_reapply_keeps_runtime_partitions` now asserts the plan after the maintenance pass is **empty**, which replaces the `DROP TABLE` and per-monthly plan checks. It then applies and reconciles a second time. Without the new block it fails with `ALTER TABLE events DROP CONSTRAINT events_pkey; ...`. With the block it passes. - It also includes the optional notes from the #8487 review: - After maintenance, it checks that both catch-alls are still present and attached, not only that the zipped bounds differ. - The first runtime monthly comes from the declared catch-all's lower bound instead of a hard-coded `p2026_07`. - The doc comment now states only what the test pins: bounds are not compared, and the plan is empty. - I broke the rebuild on purpose by re-adding the key in the wrong order. The new assertion fails the reconcile script with `events and its partitions must have PRIMARY KEY (community_id, created_at, id)`. - CLI runs against local Postgres 17: - Fresh DB: apply → reconcile → apply → reconcile → plan. The second apply reports no changes and the plan is empty. - DB reconciled with the old script: the next apply fails with SQLSTATE 42P16. After running the new reconcile script once, apply reports no changes and the plan is empty. - `events_pkey_repair_runs_before_reused_apply_and_matches_reconcile` checks two things: the reconcile script carries the repair block verbatim, and `start-relay-for-tests.sh` runs the repair before `pgschema apply`. It fails if the two copies drift. - I ran the repair script and then the bootstrap against four local probe databases: one reconciled with main's script, an empty one, one applied but never reconciled, and one with no `events` key. All four end with an empty plan. With another session holding a lock on `events`, the repair fails after 10s with the hint and leaves the key untouched. It succeeds once the lock is released. - `admin_schema_parity_between_desired_state_and_migrations` and the `runtime::migration` unit tests pass. fmt and clippy are clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-22 10:57:49 -07:00
ravarora2	2d289f720d	BUZZ-301: Add user deletion request intake (#8496) ... ## Summary Add the first testable piece of user deletion: submit a synthetic request, list requests, and inspect one by UUID. Operators can verify that intake reaches PostgreSQL before we add inventory, approval, and execution. Add one operator-global `entity_deletion_requests` table with an additive migration and matching desired-state schema. Identical submissions return the same row. Conflicting submissions fail without changing it. Only `demo:` targets are accepted, and requests stay `submitted`. Keep the commands in `buzz-deletion`, reached through a thin `buzz-admin user-deletions` adapter. Reuse the existing database connection setup. This change adds no worker, stage history, community gates, or deletion operations. ### Rollout plan This is an expand-only schema change plus an operator CLI. Existing relay code does not use the new request table. No backfill or real deletion is part of this release. 1. **Order the PRs.** Land #8496 first, using 0068; main now owns 0067 for channel join roles. Rework #8489 to build on this table with the next available migration number. Renumbering its existing CREATE TABLE migration alone is insufficient; both PRs currently create the same request table. 2. **Apply on staging.** For deployments that manage schema separately, apply the reviewed additive migration before using the new CLI. Where auto-migration is enabled, the new relay binary applies it at startup. Keep existing tables and records unchanged. 3. **Verify on staging.** Use the new `buzz-admin` binary with `DATABASE_URL` pointing to staging. Submit a unique synthetic label, list requests, and inspect the returned UUID: ```bash buzz-admin user-deletions submit --target demo:staging-intake-1 --requested-by <operator> buzz-admin user-deletions list --limit 5 buzz-admin user-deletions inspect <returned-uuid> ``` Verify one `entity_deletion_requests` row with status `submitted`. Repeat the identical submission and verify the same UUID and timestamps. Use a new label if this label was used by an earlier staging test. 4. **Apply beyond staging.** After verification, use the deployment's reviewed schema/release workflow to add the table in the remaining environments. Requests run only through the operator CLI; this release starts no deletion worker. No feature flag is needed for this synthetic intake: the database accepts only `demo:` targets, and real deletion is absent. 5. **Rollback.** Keep the additive table and saved requests; stop using the new commands and roll back the binary if needed. After 0068 is applied, an older binary with auto-migration enabled can fail at startup with sqlx `VersionMissing`. A binary rollback therefore requires migration execution to be disabled on the older relay (`BUZZ_AUTO_MIGRATE=false`, including the corresponding deployment configuration). ### Related work This is a smaller first slice of the full-workflow draft [#8489](https://github.com/block/buzz/pull/8489), which is preserved for later extraction. The two PRs overlap and should not both be merged as written. ### Testing The author submitted `demo:rarora-manual-1` to a separate local PostgreSQL 17 database.

Luke Tornquist	039e1c8d59	feat(relay): write the NIP-43 member list in the membership transaction (#8482) ... ## Summary The relay-signed NIP-43 member list (kind:13534) was published after each membership change had already committed. If that publish failed, or if a change never republished at all (startup `bootstrap_owner`), the list stayed wrong until the background reconcile sweep found and fixed it. #8467 moved that sweep off the startup path. This PR removes the reason the sweep exists. Now every `buzz-db` function that changes `relay_members` writes the new list **in the same transaction**, as its last statement before commit: - It takes the per-community list lock last, reads the members, signs the list, retires the old one and inserts the new one. - If the list write fails, the membership change rolls back and the caller gets an error. - A call that changes nothing (already a member, role mismatch, host exists, limit reached) writes no list. The functions return `MembershipWrite<T> { outcome, snapshot }`. Callers push `snapshot` to live subscribers after commit. That push is the only thing left outside the transaction; if it fails, live clients see the change on their next fetch, and the stored list is already correct. Write paths covered (RPR #2, every write path): `add_relay_member`, `claim_relay_membership`, `claim_relay_invite`, `remove_relay_member`, `remove_relay_member_if_role`, `update_relay_member_role`, `bootstrap_owner` / `provision_owner`, `transfer_ownership`, `backfill_from_allowlist`, and the owner insert in `create_community_with_owner[_and_nip_fi_issuers]`. Community deletion removes the members together with the community, so it writes no list. The relay keypair is passed in explicitly instead of being stored on `Db`, so the compiler finds every caller. ### Behavior changes - **Open relays get an accurate list too.** Provisioning and ownership transfer used to publish only when `require_relay_membership` was on. The write is now unconditional. - **Same-second changes can't reuse an id.** The list's `created_at` is one second past the newest earlier list for that community, including retired ones, or the current time if that is later. Before, adding and then removing a member in the same second could produce an event with the same id as an earlier list. The insert then failed, and the stale list stayed live. A burst of changes can push `created_at` ahead of the clock by up to one second per change; it returns to the clock once the burst ends. - **`buzz-admin add-member` / `remove-member`** no longer build their own list (`publish_membership_list_with_bump` is deleted). They push the list the database wrote. Concurrent CLI runs now serialize on the database lock rather than depending on `run.sh` running one at a time. - **Owner mutations lock the community row `FOR NO KEY UPDATE`.** `transfer_ownership` and `bootstrap_owner` used `FOR UPDATE`. The list insert takes `FOR KEY SHARE` on that row through `events.community_id`'s foreign key, so a repair holding the list lock, or a removal or role update holding a member row, deadlocked with a concurrent owner change. `FOR NO KEY UPDATE` still conflicts with archive, unarchive and deletion admission, so the lifecycle ordering is unchanged. - **Startup delivers its list to other replicas.** When backfill or `bootstrap_owner` changes members at startup, the relay fans the newest list out through pub/sub once its state is ready, so clients connected to other replicas during a rolling deploy see an owner rotation without a refetch. - **New `buzz-admin republish-members`.** Rewrites the community's list from the stored members in one community-write transaction and pushes it live. This replaces the sweep as the repair for a list that is missing or stale: a `relay_members` change made directly in SQL, a restore, or a deployment that turns on `BUZZ_REQUIRE_RELAY_MEMBERSHIP` after running without it. ## Rollout Nothing rewrites a list automatically once the sweep is gone. A community whose list drifted before this deploys stays wrong until its next membership change or until an operator runs `buzz-admin republish-members`. Either deploy #8467 and let its sweep complete one pass first, or run `republish-members` for each community after this deploys. The command repairs only the community that `RELAY_URL` maps to, so on a relay hosting many communities, run it once per community host. ## What got simpler Deleted: - `reconcile_nip43_membership_snapshots`, `spawn_nip43_membership_reconciler`, its leader lock key and #8467's standby retry - the three `nip43_membership_snapshot_needs_reconciliation*` drift reads (one already deprecated) - `publish_nip43_membership_list` / `publish_nip43_membership_locked`, the separate after-commit republish at every call site, and `buzz-admin`'s duplicate publisher - the reconcile metrics `buzz_nip43_membership_reconciliations_total` and `buzz_nip43_membership_reconciliation_failures_total` - the after-commit publish metrics `buzz_nip43_membership_publications_total` and `buzz_nip43_membership_publication_seconds`, and the `publish_nip43_membership_locked` transaction metric label. A failed list write is now a failed membership write and shows up in the caller's existing error handling and the transaction metrics of its write path. - the `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` setting There is now one way the list gets written, and it can't disagree with `relay_members` after commit. **Unused deploy config (outside this repo):** hosted deployments that set `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` can drop it. It is now ignored. Dashboards or alerts on the four deleted metrics will stop receiving data. ## Testing New Postgres tests (`buzz-db`): - `relay_members::every_membership_write_commits_its_list`: for each write path, the returned list is the single live kind:13534 and names exactly the committed members. No-op calls return no list and leave the live list alone. - `relay_members::a_failed_list_write_rolls_back_the_membership_change`: holds the list lock, waits for the join to block on it, cancels that statement, and checks that the member was not added and the previous list is still live. - `relay_members::concurrent_joins_all_land_in_the_list`: 8 concurrent joins; the final list names all 8. - `relay_members::same_second_return_to_an_earlier_membership_writes_a_new_list`: add, remove, add, remove within a second; every list is newer than the last and no id repeats. - `relay_members::owner_transfer_and_list_repair_both_commit` and `relay_members::owner_transfer_and_member_removal_both_commit`: hold a repair (list lock) or removal (member row) open, wait until a transfer blocks behind it, then finish it. Both transactions commit; with `FOR UPDATE` back in place, one of them fails. - `community::create_community_with_owner_is_atomic_and_create_only` and `relay_invite::bounded_claim_exhausts_and_existing_member_retry_does_not_consume` now also check the list. Each new test was checked to fail against a mutation of the new code that brings back the old behavior (details in the thread). Stacked on #8467. Merge order: #8467, then #8468, then this. --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-20 11:39:13 -04:00
klopez4212	c9e35f8ac7	fix(mobile): restore Solo chats from channel labels (#8466) ... Restore Solo chats and project placement on mobile using `buzz.solo` labels and creator metadata. Invalidate stale channel details when identity changes so opening and sending preserve refreshed Solo identity; shared chats retain ordinary sending. New mobile Solo chats publish the discovery label, and the personal send guard enforces ownership even when route hints or legacy placement suggest Solo. The current desktop producer lives in `block/buzz-app`. [Contract documentation](0201ca0572/docs/solo-mobile-contract.md) links its production creation call to relay identity generation and mobile regression coverage. Public metadata fields are documented. Validation: clean analysis; 3,542 mobile tests (5 skipped), 4 push checks, and 280 core unit/doc tests passed. Removing the cache fix reproduces the send failure. Local push hooks were skipped with owner approval after an unrelated terminal timeout and disk exhaustion; full local CI is not green. GitHub CI must validate the pushed commit. The initial build was installed/launched on iPhone; follow-up native and live cross-client confirmation remain pending. The ownership regression supplies a valid owned member recipient and checks the exact rejection. A New chat UI test captures the real signed kind-9007 command. Both regressions were mutation-verified: removing the ownership guard or the production creation label causes the corresponding test to fail. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz>	2026-10-20 11:10:24 -04:00
Wes	edbfbf08db	test(mobile): journey-first testing guidance and suite cleanup (#8397) ... ## Summary This PR does two things. It updates the mobile testing conventions to favor a few journey tests over many small logic tests. It also applies those conventions to the existing mobile suite, one commit per step. ### Testing conventions (`AGENTS.md`, `mobile/README.md`) - Start with one widget journey per user-visible flow, driven through the real widgets, notifiers and coordinators. Assert what the user sees and what is durably saved. - Cover retry, cancel and resume as steps inside the journey, not as separate tests. - Fake only external boundaries (network, relay, OS, browser, storage). - Use focused, table-driven tests only for security and data-loss invariants, protocol or crypto vectors, and pure functions with many input combinations. - When review finds a defect, extend an existing journey or table instead of adding a test per finding. - Delete a lower-level test only once a journey demonstrably catches the same failures. - Every test must fail when the production code it guards is broken. These conventions keep the Review-Proven Rules' safety bar and change only how coverage is organized. ### Suite inventory and plan The suite has 234 Dart test files, about 110k lines and about 2,600 declared tests. Native tests are separate: BuzzPushKit, RunnerTests, NativeControlTests and Android. Line-saving estimates are hypotheses, not a deletion budget. Each deletion needs a replacement that rejects a representative production mutation. 1. **CI and reliability.** Run the native tests CI skipped, make time-dependent tests deterministic, and make tests that could not fail falsifiable. *(done, see below)* 2. **Shared harness.** Add one fake relay (socket plus HTTP boundary, with the real `RelaySessionNotifier`) in `test/helpers/`. Today 38 files each write their own `RelaySessionNotifier` fake. *(done, see below)* 3. **Per-area journeys.** Convert page tests that fake the flow's own notifiers (for example, `channel_detail_page_test` overrides about 60 providers). Fold near-duplicates into tables. Remove constant-pinning, pixel-geometry and call-count tests once a journey covers the outcome. Split `channel_detail_page_test.dart` (17.7k lines). Each area commit reports before/after counts and the mutation it rejects. 4. **CI speed.** Shard by file instead of by test, since every shard currently compiles the whole suite. *(done, see below)* Keep as-is: relay protocol and NIP handling, crypto vectors, auth, push security, persistence and journal invariants, recipient routing, and real-socket transport and cancellation tests. ### Step 1 changes - **Android CI** runs the 23 JVM unit tests, which were never run before. It retries the APK build once, only on SDK or plugin download failures (the cause of 4 recent `main` failures). - **iOS CI** runs all RunnerTests (previously 2 of 99) and the previously uncalled Me-agent accessibility script. The Swift Native lane builds the simulator app once, in the background while the simulator boots and runs the native-control scripts, instead of twice. The lane stays non-required. - **Stale RunnerTests.** Two reaction-details tests still expected the filter list that #8280 replaced; they now cover the toggle list. #8393 moved navigation bar controls onto a shared glass surface and made unknown Tabler symbols assert. The avatar and members-activity tests now find controls on that surface, three tests use real symbol names, and a 240 pt title width pinned to the old control sizes is removed (its gap assertions remain). - **Known bug, not fixed here.** Since #8393 the DM title avatar image is nil, because `makeItem` returns avatar data as a custom-view item. No screen passes a title avatar yet. The test marks it `XCTExpectFailure`. - **Typing retry** and **sections backoff** tests use fake time instead of about 37 s of real sleeps and a `Stopwatch < 100ms` threshold. - **Manage-channel sheet tests** previously asserted inside callbacks that the sheet's `catch (_)` swallows. A wrong saved description made the test loop until killed. The tests now record arguments, assert outside the caught code, and cancel instead of re-presenting endlessly. - **`video_viewer_transport_test` removed.** It exercised only `package:http`. Removing the production `request.sink.close()` already fails `video_viewer_test`. ### Step 2 changes - **`test/helpers/fake_relay.dart`** fakes only the websocket (through the session's socket factory) and the HTTP bridge (through its client). The real `RelaySessionNotifier` still connects from `build()`, handles OK and CLOSED, batches events, backs off and replays subscriptions. - The fake serves the NIP-CW channel window. It can hold OK and live echo independently, reject a chosen publish, and drop the connection. Any request it cannot answer faithfully fails the test at teardown, because the app often catches relay errors and falls back. - **`channel_messages_journey_test`**: history through the channel window, a live message, a send that is pending until OK and stays one row after the echo, a rejected send rolled back, then drop and reconnect with missed and later messages. - **`channel_send_journey_test`**: type and send on `ChannelDetailPage` with no feature-notifier overrides. The row and sending spinner show at once, OK settles them, and a rejected send puts the text back in the composer and shows a snackbar. - Existing per-file relay fakes and `SidebarRelay` are unchanged. Step 3 migrates them area by area. ### Step 4 changes - `scripts/mobile-test-shard.sh` splits the 235 test files across the 3 shards, balanced by line count. `flutter test --total-shards` split tests, so each shard compiled and loaded every file. Locally at 4 workers, one shard took 63 s instead of 73 s and used 40% less CPU. `channel_detail_page_test.dart` (17.7k lines) is now the long pole; splitting it in step 3 shortens the slowest shard. Out of scope here: requiring branches to be up to date before merge (a repository setting), and the onboarding tests in #8375. ## Validation - Mutation checks: - Typing retry bound: test fails. - Sections backoff reset: test fails. - Wrong saved description: fails in about 11 s. The old tests hung instead. - Removed sink close: `video_viewer_test` fails. - Changed Dart files pass locally, and `flutter analyze` is clean. - Android `testDebugUnitTest` passes locally (23 tests). The Me-agent accessibility script passes on a local simulator. - Step 2 mutation checks, each made a journey fail: accepted OK ignored, rejected row not rolled back, optimistic row not added, draft not restored, local message left pending after OK, channel window replaced by the fallback, live subscriptions not replayed after reconnect. - Both journeys run in about 1 s on fake time. - All 99 RunnerTests pass on an iPhone 16 iOS 26.5 simulator, the CI destination, after rebasing on #8398. - The shard script partitions all 235 test files exactly once. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Carl <32a2e2c9d428ee08902cab75d956da2c1d235a22d4766b0dd4138bf6e2e5db1d@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-19 17:19:07 -06:00
Will Pfleger	91e7b469b8	fix(relay): wait for the peer's Close before dropping any WebSocket (#8426) ... 🤖 A NIP-42 login refused for a NIP-FI key mismatch could reach the client as an abnormal close (`1006`, no reason) instead of the `NOTICE "restricted: authorization denied"` followed by close `1008` that every other authorization denial produces. The relay did write the NOTICE and the `1008` Close, but the connection task dropped TCP as soon as the writer finished, before the peer finished the close handshake. The client could then lose frames it hadn't read yet. It depends on timing, so it showed up intermittently and is not specific to key pairing. ## Relay route - `recv_loop` now hands back the read half even while a frame handler is still running. Frames are handled one at a time while the connection is live. Once it is cancelled, an in-flight handler (for example a Nostr `CLOSE` waiting on the subscription lock behind a REQ stuck in Redis) is spawned to finish instead of holding the reader. It is never dropped partway, so subscription retirement stays atomic, and cleanup joins it before the expiry barrier and application cleanup. - As soon as the writer finishes, `await_client_close` keeps the transport open until the client's Close arrives or the stream ends. It runs concurrently with joining the heartbeat, auth-timeout, expiry and auth-cancel tasks and the connection's application cleanup (subscriptions released, registry entry removed, presence cleared). Cleanup never waits on the peer, so a nonresponsive client cannot delay registry counts, presence or `has_admitted_connection`. The socket never waits on cleanup, so a stalled Redis (the pool has no wait timeout) or an expiry join blocked on its quiescence barrier cannot hold the socket and its file descriptor open past the bounded wait. The active-connection gauge and the connection permit are released after both finish. - The connection permit (`BUZZ_MAX_CONNECTIONS`) is now taken at the start of `handle_connection`, before the NIP-FI gate and the community-active bootstrap check, and held through the active handler or the refusal drain and its bounded wait. Previously a socket in bootstrap, or refused there, held no permit, so a burst of refusals could open sockets beyond the limit. Over the limit, the socket is still dropped with no frames. `buzz_ws_connections_active` still counts only connections that reached the active handler. ## Huddle-audio route - The relay and audio bootstrap drains share one bounded helper. A socket refused before admission waits after its community registry entry is released. - Every exit of the audio handler gets the bounded peer wait. Exits whose cleanup follows their terminal frames (`room_full`, `room_ended`, version mismatch, archived channel, owner rejection or unreachable, failed commit confirmation) and the normal teardown hand the socket to a background task that waits for the client's Close, so lease releases, `48102` writes and room archiving on Postgres and Redis never hold the socket open. The remaining exits send their frames last, and `handle_active_audio_connection` waits once they return. The wrapper joins the background task before returning, so the audio connection permit is held until the socket ends, as on the relay route. - Audio error exits now follow their existing JSON error with a Close frame: | Exit | Close code | | --- | --- | | `huddle_relay_draining` | `1012` service restart | | `join_rejected` (owner resolution failed), `huddle_owner_unreachable`, failed channel lookup | `1011` internal error | | `huddle_audio_unavailable`, `unsupported_version`, `upgrade_required`, `room_full`, `room_ended`, archived channel, owner rejection, NIP-FI authorization denial | `1008` policy | Audio login failures and authorization refusals outside NIP-FI `authorization_denied` still send only their existing error frame, then get the bounded wait. - The audio read half is an enum, so the hand-off has no `expect()` that can panic. ## Timing - The peer wait is bounded by `WS_TERMINAL_FLUSH_TIMEOUT` (1s), and drains to end-of-stream so a client-initiated Close gets its reply. The terminal writer flush has its own 1s budget, so the worst case for terminal transport work is about 2s per refused or closed socket. - Terminal frame writes (`flush_terminal_frames`, `send_exit_frames_bounded`) still give up on the first failure, but a failed or timed-out send is now logged at `debug` instead of being discarded. - The graceful-shutdown comment in `main.rs` now describes per-stage budgets (restart jitter, restart-Close acknowledgement, terminal flush, peer wait) rather than a per-socket total. The 30s hard drain bounds every socket, and the 35s process shutdown budget fits within the chart's 60s `terminationGracePeriodSeconds`. ## Tests Real-socket tests in the infra-free relay lane of `just test-unit` and `scripts/run-tests.sh` unless marked PostgreSQL: - The key-mismatch login and a session-expiry denial (as a control) both assert NOTICE then `1008` / `authorization denied` on the wire. - A raw-TCP client that never answers Close: the relay holds the socket for at least the bounded wait, has deregistered the connection by the time the socket ends, and ends it on its own under a 10s watchdog. - A raw-TCP client that withholds its Close until the connection has deregistered: the relay ends the socket in under the 1s cap, which fails if cleanup waits on the peer. - A raw-TCP client that never answers while final cleanup is stalled at a test pause point: the socket still ends after the bounded wait. - A raw-TCP client that never answers Close on the relay bootstrap drain, the audio bootstrap drain and an early audio-handler exit: the relay holds each socket for the bounded wait. - On the relay route with a one-slot budget through the real `handle_connection`: a refused bootstrap holds the slot until its socket ends, and a bootstrap stalled on the community check already holds the slot before the AUTH challenge is sent. - An established relay session whose reader is blocked in a Nostr `CLOSE` handler on a held subscription lock when the session expires: the socket ends within the bounded wait while the lock is held, and cleanup completes with the subscription retired once it is released. - An established relay session whose expiry task is stalled behind a held session effect permit: the socket still ends within the bounded wait. - PostgreSQL: an established audio session whose teardown is stalled after its Close, and a stalled archived-channel exit, both end within the bounded wait from the hand-off. - PostgreSQL: a fast refusal (unsupported protocol version) through the real `handle_audio_connection` with a one-slot permit budget keeps the permit taken until that socket ends. - PostgreSQL: `huddle_audio_unavailable` sends its error and then Close `1008` as the very next frame. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-19 16:13:27 -04:00
Tom Brow	5730c83f7d	fix(release): keep mobile candidates pinned as branches advance (#8454) ... Mobile candidate publication currently fails if the source branch advances after selection, and the operator can report failure even after the correct immutable tag was created. It also prevents releasing an explicitly selected historical baseline. Add `--commit FULL_SHA` and independently verify in the operator and publisher that the selected commit belongs to the selected source branch's history. Compare immutable SHAs, keep the candidate pinned through publication, and verify the resulting annotated tag instead of requiring the branch to remain stationary. Stable-branch review/check protection and immutable-tag permissions remain enforced. Without `--commit`, selection still defaults to the current source tip. ### Validation - Updated operator and publisher contracts pass: historical main/stable selection, branch advancement during publication, unrelated or missing commits, ancestry lookup failure, and unchanged tag/sequence checks. - Removing ancestry enforcement causes the unrelated-history regression to fail. - Live read-only ancestry verification accepts the original 0.24 baseline. Local publication stops at the existing App-permission check; no tag or build was created. - Full local `just ci` passed. Signed-off-by: Tom Brow <tomb@block.xyz>	2026-10-19 16:21:11 +00:00
Will Pfleger	5b433d9292	feat(relay): resolve NIP-FI issuer bindings from the database (#8377) ... Stack: #8372 (merged) → this PR → #8399 → #8401 Makes relay login checks read the per-community NIP-FI issuer bindings that #8372 stores. Without this, the relay can't keep up with bb-public, where new communities are created at every signup and a static `BUZZ_NIP_FI_COMMUNITIES` list won't do. **Source switch.** `BUZZ_NIP_FI_COMMUNITY_SOURCE=database` resolves each community's trusted issuers from `community_nip_fi_issuers`, filtered by the issuer registry, instead of the static list. Each community gets its own policy ID: the base ID no longer hashes every community audience, and the final ID hashes the base plus this community's audience, so policy IDs change once (see `docs/operator-nip-fi-bindings.md`). `Config::from_env` refuses to start, in every mode, on an unknown source, on `database` together with `BUZZ_NIP_FI_COMMUNITIES`, and on `database` without `BUZZ_NIP_FI_PROVISION_BINDING`. `BUZZ_NIP_FI_RESOLVER_*` and `BUZZ_NIP_FI_SNAPSHOT_*` are validated in every mode, so a bad value fails the deploy that sets it. In `off` mode no resolver is built and no snapshot is loaded. **Resolver (`nip_fi_resolver.rs`).** - **Snapshot:** each pod loads every binding into memory, capped at `BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` (going over is a failed load). It refreshes every 30 s, start to start, with jitter that only shortens the delay and backoff after failures. Each attempt is limited by `BUZZ_NIP_FI_SNAPSHOT_REFRESH_TIMEOUT_MS`, which must be shorter than the interval. A refresh whose deadline passes before it publishes publishes nothing. The old snapshot is dropped off the runtime. - **Freshness:** a host in a snapshot loaded under two minutes ago is answered from memory. Any other host, and every host once the snapshot is stale, goes to a live lookup. Every answer carries a deadline two minutes after the read behind it started, and WS, HTTP and audio recheck it just before admitting. - **Live lookups:** bounded and single-flight. In-flight lookups are capped by `BUZZ_NIP_FI_RESOLVER_MAX_INFLIGHT` (default 8, clamped below the database pool size), and the pending hosts and their waiters have fixed caps. Positive answers are used for that admission only. A "not found" is cached for 5 s, up to `BUZZ_NIP_FI_RESOLVER_NEGATIVE_CACHE_MAX` hosts, and only when no snapshot was published and no binding was created while it ran. A lookup that panics still leaves the pending map. - **Removal:** a removed binding stops admitting new connections within 30 s plus the refresh timeout (40 s by default) while refreshes succeed, and within two minutes of the last good load while they fail. Open WebSocket sessions are not rechecked when a binding is removed; they end at their own session deadline. **Shadow mode** resolves through the same path as enforce, including the database lookup and the freshness rules. It keeps the resolved binding's deadline and checks it at the same point as enforce; a binding that goes stale during the tenant lookup is recorded as `stage=deadline, outcome=unavailable`, without changing the legacy response or closing the socket. With `source=database` its `community` metric label is only `bound` or `unmapped`; with `source=env` it keeps the existing per-community audience label, so current shadow dashboards are unchanged. Each request resolves its Host once: the router guard's resolution, failures included, is reused by shadow recording and admission. **Provisioning.** Both operator provisioning paths drop this pod's cached "not found" for the new host after a commit that bound issuers, so the creator's first login looks it up. **Startup and readiness.** With `source=database` and a mode other than `off`, the first snapshot loads before any listener binds, under its own startup phase `nip_fi_snapshot_load`. A failed load exits non-zero, so a pod is never ready without a snapshot. **Operational consequence:** boot already fails when the database is unreachable; what is new is that a snapshot over `BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` or a load past its timeout also crash-loops new pods. After two minutes the old pods' snapshots go stale and most logins fall through to the 8-slot live lookup, which sheds the rest with 503. The way out is raising the cap or timeout, or `mode=off`. **Metrics.** `buzz_nip_fi_binding_snapshot_*` covers loads, failures, rows and freshness. `buzz_nip_fi_binding_snapshot_loaded_timestamp_seconds` is written on every refresh attempt, so alert on `time() - x > 120` together with `absent(x)`. `buzz_nip_fi_binding_snapshot_rows` against `buzz_nip_fi_binding_snapshot_max_rows` gives the headroom to the row cap. `buzz_nip_fi_resolver_*` covers live lookups and the negative cache. The env vars and alerts are documented in `.env.example`, the chart README and `docs/operator-nip-fi-bindings.md`, which also has the staged off → shadow → enforce rollout for `source=database` with go/no-go signals at each step, and the over-cap and load-timeout failure modes with their ways out. **Regression coverage.** Router-level tests run the database resolver through the real `build_router` for root WS, audio and protected HTTP, in enforce and shadow mode. Over PostgreSQL and Redis, two pods using the env community source (two exact bindings) replay assertions retained from before a disconnect through a real root NIP-42 session, the audio deny-set check and signed NIP-98 requests: they are denied on both pods, and a root session upgraded before the disconnect is refused by the post-registration deny-set check. Postgres tests in `buzz-db` check that archived and quiescing communities, and issuers missing from the registry, never reach the snapshot or the live lookup. Process-level `boot_lifecycle` tests spawn the real relay with `source=database`: an over-cap or timed-out startup load exits non-zero with no health listener bound, and a loadable snapshot lets readiness turn ready. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-19 10:32:18 -04:00
Tom Brow	30ca980b49	feat(release): support version-matched mobile stable branches (#8430) ... Mobile candidates currently require the current `main` commit, so a stable release branch cannot publish through the existing protected tag workflow. Add optional `--source-branch mobile-vMAJOR.MINOR` selection while preserving `main` as the default. Both the command and App-backed publisher reject a stable branch whose major/minor differs from the requested version. Candidates retain exact-tip checks and immutable annotated tags; the private build pipeline is unchanged. Document the temporary stable-only distribution policy and explicit per-fix backport decisions. No candidate, build, or upload is triggered by this change. No duplicate implementation was found among open release PRs. Stable publication now checks active review and status-check protection in both the operator and publisher. The process permits approved backport PRs and stable-only corrections for regressions caused by earlier backports. Administrator activation and verification of the no-bypass ruleset remain outstanding; non-admin API responses hide the bypass actor list. ### Validation - Full local `just ci` passed during preparation; the final changes affect shell release tooling, its workflow inputs, CI path detection, and documentation. - Publisher contract passed, including version-matched stable sources and mismatched branch rejection. - Operator contract covers default main, a divergent stable commit, missing or mismatched sources, immutable sequencing, and publication races. The final operator contract run passed. - Updated publisher and operator contracts pass, including 17 weakened-policy cases and rejection of unavailable protection. The live, currently unprotected stable branch is rejected. --------- Signed-off-by: Tom Brow <tomb@block.xyz>	2026-10-18 18:04:04 -07:00
Will Pfleger	6286a54321	feat(relay): store per-community NIP-FI issuer bindings (#8372) ... Stack: this PR → #8377 → #8399 → #8401 bb-public creates communities all the time, so a hand-edited `BUZZ_NIP_FI_COMMUNITIES` map can't list them. This PR stores an explicit NIP-FI issuer allowlist for each community in the database and writes it when the community is created. Login checks don't read the table yet; that comes in #8377 together with the database-backed resolver. Operator steps are in [`docs/operator-nip-fi-bindings.md`](docs/operator-nip-fi-bindings.md). **Storage.** Migration `0066_community_nip_fi_issuers` adds `community_nip_fi_issuers (community_id, issuer, created_at)`, with primary key `(community_id, issuer)` and the community write fence attached. The assertion audience is `https://<communities.host>`, so the table has no `aud` column. Zero rows means no binding. The table is included in whole-community deletion and purge. **One bindable rule.** `BUZZ_NIP_FI_PROVISION_BINDING` (`{"host_suffix": ..., "authorized_issuers": [...]}`) is parsed in `buzz-auth` with `BUZZ_NIP_FI_ISSUERS`, whatever `BUZZ_NIP_FI_MODE` is set to, and both the relay and `buzz-admin` use the same parser. Each authorized issuer must be a configured issuer (1 to 2048 bytes), and the suffix must not cover any host declared in `BUZZ_NIP_FI_COMMUNITIES`; an unreadable declaration refuses startup even in mode `off`. `ProvisionBindingPolicy::is_bindable(host)` is true for a host exactly one label under the suffix that is not reserved. It decides creation-time binding, explicit `bind`, and what the lookup route reports. **Binding on creation.** Rows are written in the same transaction as the community insert on all three creation paths (`POST /operator/communities` `create_only`, its legacy convergence branch, and startup bootstrap), and only when the call actually created the community, so existing rows are never rewritten. **Reserved host.** A host whose `https://<host>` equals a configured `command_audiences` value never holds a binding. Operator provisioning of it is rejected with a 400 and the `reserved_host` error code, bootstrap creates it unbound, and the availability route reports it unavailable with an error code. `main.rs` calls `verify_reserved_hosts_unbound` at startup; if a reserved host has rows the relay refuses to start and names the fix (`buzz-admin nip-fi unbind --host <h> --issuer <i>`, or revert the command audience). A database failure during that check is a separate `Check` error. **Operator commands.** - `buzz-admin nip-fi backfill` pages unbound communities by host (1000 per page) and binds each page with one `INSERT ... SELECT` limited to active communities. It skips communities being deleted, always prints `{rows_bound, unbound, unbound_hosts, truncated}`, and exits non-zero while any bindable community is still unbound. Archived communities are bound on purpose. Both bind paths take the shared deletion lock and then lock the community row (`FOR NO KEY UPDATE`, in id order for a batch), the same order deletion uses, and the backfill insert also requires the community to still have no binding, so an operator `bind` that lands after the backfill listed a community wins and the default issuer is not added beside it. - `buzz-admin nip-fi bind --host --issuer` refuses a reserved host, a host outside the suffix, or an unconfigured issuer. - `buzz-admin nip-fi unbind --host --issuer` refuses to remove a community's last issuer (archive or delete the community instead), with one exception: when a valid provisioning policy shows that backfill can't bind the host (it's reserved, or outside the suffix), the last issuer can be removed. That is the reserved-host recovery path in the runbook. A missing or malformed policy doesn't block `unbind`; it just means the exception never applies. **Lookup route.** `GET /operator/communities/nip-fi-binding?host=` (NIP-98, `RELAY_OPERATOR_PUBKEYS`) reads the database and returns `{host, active, issuers[]}`. `host` is the stored host. It returns 404 for an unknown host, 200 with `active:false` for an archived or quiescing community, and `issuers:[]` when no provisioning policy is set. It lists only issuers that are configured and on a bindable host. kgoose depends on this contract; it is also documented in the runbook. **NIP-FA.** The `relay_url` bullet now also says: "An adapter MAY obtain its exact relay list from a configured, authenticated source; it MUST still compare `relay_url` exactly." **Deployment dependency.** The kgoose config side is already handled by [cash-server#137671](https://github.com/squareup/cash-server/pull/137671). In public-community mode it requires the command audience not to be a community audience. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-17 13:13:49 -04:00
Tom Brow	d79446316b	fix(mobile): support DeviceHub in mobile-dev (#8404) ... `just mobile-dev` fails on Xcode 27 machines that have DeviceHub instead of Simulator. Resolve the simulator frontend inside the selected Xcode installation: DeviceHub for Xcode 27, or Simulator for Xcode 26. Launch by full path so an older installed or running app cannot determine the choice. This extracts the still-needed DeviceHub portion of Wes's [#8330](https://github.com/block/buzz/pull/8330). The CocoaPods deployment-target work already landed in [#8379](https://github.com/block/buzz/pull/8379); this PR does not change Podfile or its lockfile. CI and pre-push mobile selection include the shared Justfile and mobile recipe regression script, so edits to either run the regression in the mobile gate. ### Validation - Nine production-recipe checks pass, covering side-by-side Xcode 26/27 selection with spaces in paths, missing apps, launch failure, and gateway argument forwarding. Mutations reject unqualified Launch Services lookup and removal of DeviceHub selection. - All 39 tests of the pinned paths-filter action pass, including the Justfile and recipe-test selection cases. Mobile formatting, analysis, and the full mobile suite pass. - Native macOS smoke checks exercised launch from the selected Xcode installation and reached the Flutter boundary. Flutter and identity setup were stubbed, so no app was built or installed. - The initial full local CI gate stopped on an unchanged ACP signal-cancellation test; that exact test passed in isolation. The initial pre-push run also hit missing dependencies and two unchanged desktop agent-discovery tests. Desktop lint and TypeScript checks passed after installing pinned dependencies. Publishing used the authorized local-hook exception. - Current-head [CI](https://github.com/block/buzz/actions/runs/38963831198) passed, including all nine recipe cases and native Swift validation.

Brad Seiler	2d0f78c6e1	feat(auth): support explicit mesh JWKS transport (#8382) ... ## Summary Allow an issuer to opt into mesh HTTP for its JSON Web Key Set (JWKS). Public HTTPS remains the default. This supports deployments whose service mesh authenticates and protects the key endpoint. The sealed source contract selects transport and contributes to policy identity. Mesh mode requires a DNS hostname and checks every resolved address against an explicit allow-list before pinning one address. Both modes disable proxies, reject redirects, cap responses, and enforce a whole-fetch deadline. The relay cannot verify mesh security: operators must enforce mutual TLS, endpoint authorization, and egress restrictions. ### Related issue No duplicate mesh-JWKS issue or PR found. Existing NIP-FI relay enforcement: #7224. No deployment change is included. ### Testing - At `eccb8cb19420abda44cf6e5e62b1361e2843bd1d`: full auth package and auth/relay all-target clippy passed. Full relay package passed: 1,457 library tests, 37 binary tests, and 9 boot tests; 446 tests were ignored. - At prior head `113939838cd81d5e8d0b0f8783c42ffaae44a4d3`: the full relay library suite failed the demo echo test (1,455 passed, 1 failed, 440 ignored). Independent checks reproduced that timeout at base `d61fe2071d2b3d8e56dd931947f16bfe0d6173fe`; the receive-cancellation defect is outside this change. A later pass does not establish that defect is fixed. - Three falsifying mutations at `eccb8cb194` were caught: mixed DNS answers, proxy bypass, and whole-fetch deadline. The full locked auth package passed after restoring the exact source. - At `eccb8cb194`, `cargo build --locked --release -p buzz-relay -p buzz-cli -p buzz-admin` passed with command-local `CARGO_PROFILE_RELEASE_STRIP=none`. This avoids a macOS loader error without a source, lockfile, or project-profile change. - Earlier hooks failed the ACP signal test and Tauri login-shell PATH test. The ACP failure also reproduced on unmodified main `93ffc37c`. Main merged without conflict. The full Tauri package then passed with `RUST_TEST_THREADS=1`: 3,422 library tests and 3 integration tests, 19 ignored. All pre-push hooks passed with that same command-local setting; no hook or test was skipped. - At `eccb8cb194`, isolated `just test` passed all 107 runner steps. The monolithic `just ci` run timed out after 1,120 seconds; all recipes passed across that run and separate `just desktop-tauri-test`, `just web-build`, and `just mobile-test` invocations. No monolithic pass is claimed. - Exact-head release live-local checks passed: loopback HTTP mesh JWKS warm; valid assertion 101; expired/wrong issuer/wrong audience 403; valid signed disconnect 200; wrong command audience 403. Redirect-only JWKS returned assertion 503 without a request to its target. Both omitted/default and explicit public transport rejected HTTP at startup. - A separate NIP-FI-off release CLI smoke test created an open channel, sent an accepted message, read it back, and fetched its thread. The assertion probe closes after upgrade; it does not prove a complete NIP-42 session. Local loopback tests do not prove deployment mesh authentication, endpoint authorization, egress controls, or real `240/4` routing.

Luke Tornquist	c0ab789499	feat(buzz-db): retire the channel-TTL trigger (#8210) ... ## Summary This drops the channel-TTL event trigger. The application already refreshes ephemeral-channel deadlines in the event transaction (`event_follow_up::refresh_channel_ttls`, from #8135), so the trigger only repeats that work. This PR originally retired both follow-up triggers. #8352 has since retired the push-match trigger in migration 0063, so after the rebase this PR covers only the TTL half. Migration `0065_retire_channel_ttl_trigger.sql`: - `SET LOCAL lock_timeout = '5s'` (the same bound as 0063) - drops `events_refresh_channel_ttl` and `refresh_channel_ttl_after_event_insert()` Dropping the trigger on the partitioned parent also drops its partition clones. Published migrations, including 0022 and 0024, stay checksum-frozen. The same objects are removed from `schema/` (`schema/functions/…`, `schema/triggers/events.sql`, `schema/schema.sql`) and from the pgschema reconcile script. After this, migrated and desired-state databases have no event follow-up triggers. Tests: - `follow_up_retirement_tests.rs` (renamed from `push_retirement_tests.rs`): the push-retirement upgrade test now stops at 0063. A new test upgrades 0064 → 0065 and checks that the TTL trigger is gone from the parent and every partition, that the function is gone, and that the published checksums haven't changed. - `event_follow_up_postgres_tests.rs`: the contract now has two arms. `AppOnly` is the shipped schema, where both triggers are absent. `Dual` reconstructs the historical overlap of both triggers. The `PushRetired` arm (the push trigger dropped, the TTL trigger kept) was the shipped state before this PR. Its tests are removed because `Dual` and `AppOnly` together cover it. - `embedded_migrator_contains_consolidated_initial_schema` pins the 0065 statements and checks that both objects are absent from the desired schema. **Deploy gate:** do not run 0065 against a database still served by a relay older than #8135. After 0065, raw SQL writers no longer refresh TTL deadlines. `docs/push-gateway-deployment.md` is updated to match. ### What got simpler The trigger and the app no longer both refresh TTL deadlines; the app is now the only producer. One plpgsql function and one trigger are gone from both schema paths, and 8 per-partition drops are gone from the reconcile script. The follow-up contract drops from three arms to two. ### Related issue BUZZ-313 (Linear), part of the trigger-retirement work. ### Testing Head is `4f7d0baf0`. Results below are at `678927730` unless noted. `678927730..4f7d0baf0` changes only one test in `crates/buzz-db/src/store/event.rs`, described in the first bullet. - **Fixed test, `permanent_channel_event_commits_do_not_lock_the_channel_row`** (`4f7d0baf0`). - **Why it changed:** after 0065, its raw-pool inserts no longer ran any TTL refresh, so the test passed whatever `refresh_channel_ttls` did. This was raised in review. - **What it does now:** it inserts through the production `AdmittedTx` path and keeps the barrier and the tuple-lock probe. It commits all N transactions while an external transaction holds `FOR SHARE` on the channel row. It also asserts that no `buzz_db_channel_ttl_refresh_failures_total` is counted. - **Mutation check:** with `SELECT … FOR UPDATE` injected into `refresh_channel_ttl`, the new test fails (`must not wait on the channel row`, timeout at 10s). The old test passes under the same mutation. - **Blox:** fmt and `buzz-db` clippy pass. - **GitHub CI at `4f7d0baf0`:** every required check passes (56 pass, 0 fail). CI builds the merge ref with `main` `93ffc37cb`. - **New and renamed tests, checked by name in the CI logs at `4f7d0baf0`.** These pass in PostgreSQL Domain / PostgreSQL Tests ([117033725006](https://github.com/block/buzz/actions/runs/38915998692/job/117033725006)): - `permanent_channel_event_commits_do_not_lock_the_channel_row` - `migration_schema_ttl_retirement_drops_every_partition_trigger_and_keeps_checksums` - `migration_schema_push_retirement_preserves_ttl_and_published_checksums` - `event_insert_ttl_refresh_handles_permanent_ephemeral_duplicate_and_activation_race` - `{desired,migration_schema}_event_follow_up_contract_{dual,app_only}` (four tests) `embedded_migrator_contains_consolidated_initial_schema` passes in Rust / Unit Tests ([117024125423](https://github.com/block/buzz/actions/runs/38915998692/job/117024125423)). No `*_push_retired` test runs anywhere. - **Blox gates at `678927730`** (private PG16 + Redis, on a workstation shared with other sessions): - `cargo fmt --check`, workspace `clippy -D warnings` and `buzz-db --lib` all pass. - The `buzz-admin`, `buzz-audit`, `buzz-deletion`, `buzz-push-gateway`, `buzz-search` and `buzz-workflow` Postgres packages pass. - `buzz-db`: 517 of 519 tests passed. The 2 that hung, both `writer_pool_*` tests, were killed. `buzz-relay`: 413 of 426 passed. The 13 failures are covered below. - **Uncontended reruns at `4f7d0baf0`** on a fresh, idle workstation (PG16.15, `competing=0` for every arm): - **`writer_pool_rejects_non_read_committed_database_default` predates this PR.** It timed out 3/3 at head and 3/3 at `main` `93ffc37cb`, with a 300s timeout per run. - **`writer_pool_metrics_stop_after_session_timeout_setup_failure` also predates this PR.** It timed out 2/3 at head and 2/3 at `main`, and passed in the remaining run on each side. - Both tests pass in CI. The gate accepts them as a named exception for this PR, as a pre-existing hang on the PG16 test environment. - **`buzz-db`:** 518 of 519 tests passed. The single failure is `writer_pool_rejects_non_read_committed_database_default`, killed after it hung (the exception above). - **`buzz-relay`: still open.** 413 of 426 tests passed. The same 13 `handlers::group_state_postgres_tests` failed as on the shared box, each panicking at once in its fixture's `ensure community` step with `Sqlx(PoolTimedOut)`. Contention does not explain them. The fixture's community setup is in `buzz-db`, which this PR changes. A head/`main` comparison of the full `buzz-relay` package on the same idle box is running to find out whether this predates the PR. All 13 pass in CI at this head. - **E2E (Gimli, Blox)** at `050e593af`. `050e593af..678927730` changes only tests and docs; the migration, schema and runtime code are byte-identical. Gimli's audited verdict: **EXERCISED AND WORKS**, for DB and relay runtime only. Gimli ran it at `050e593af`; this head's runtime is byte-identical but was not freshly executed. - **Upgrade:** a real relay startup took the schema from 0064 to 0065. That removed the TTL function and the trigger from the parent table and from all 8 partitions. Checksums for migrations 1–64 are unchanged. - **Lock-timeout rollback:** with a real lock held, the migration failed with `55P03` at 5.0007s and the schema rolled back fully to 64. Once the lock was released, a retry applied 65. - **Fresh desired schema:** after pgschema plus reconcile, the retired objects are absent. - **Real signed kind-9 sends:** on both schema paths, these refreshed ephemeral-channel deadlines to about +600s. Permanent channels stayed NULL. - **Raw SQL insert:** at 64 it refreshed the deadline. After 65 it left the deadline unchanged, on both the upgraded and the fresh schema. - **Not covered:** native or device testing, and deploy. - **Review:** Legolas found 0 P0 and 0 P1. His three optional P2s are fixed in `678927730`. - **No human app test:** this is a DB-only change. - **Migration numbering:** #8237 and #8372 also add a `0065_*` migration. Whichever PR merges second must renumber. --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-16 11:22:21 -04:00
Logan Johnson	f148c0f22c	feat(relay): add profile search over name and display_name only (#8301) ... 🤖 > **Review as a pair with block/buzz-app#1084** (the app change that uses this endpoint). Either can merge first: the app falls back to the old search on relays without this endpoint. ## Summary Searching for a person by name over the relay's general search returns profiles that only *mention* the text somewhere else: in an avatar image embedded as text, in the bio, or in the verification address. A search for "wes" could fill every result page with profiles whose avatar data happens to contain "Wes", and never return the person actually named Wes. This adds a relay endpoint, `POST /profiles/search`, that looks only at a profile's **name** and **display name**. Every other profile field is ignored. **Matching and paging are the same as the relay's existing full-text profile search** (NIP-50 search over kind:0 profiles with `search_mode: "prefix"`). A client can switch to this endpoint without a visible change in which people a query finds: - Each query word must match a whole word of the name; the last word can be a prefix. Words can be in any order, so "johnson wes" finds "Wes Johnson". Case is ignored. - Pages work the same way: up to 100 results per page, up to page 1000. - The results are exactly the old results minus profiles that match only outside their names. The order is better for people search: exact name first, then names that start with the query, then names with a later word that starts with it, then other matches. Ties are ordered by `ts_rank_cd` over the two name fields only (not the whole profile, as in NIP-50), then newest first, then event id. The response is a JSON array of the original signed profile events (Nostr kind:0), so clients can verify them as they do today. The buzz-app client change is block/buzz-app#1084. ## Details - Request: `{"query": "wes", "limit": 20, "page": 1}`. `query` is 1–100 characters after trimming; `limit` is 1–100 (default 20); `page` is 1–1000 (default 1); unknown fields are rejected with 400. - The search reuses the full-text search's own query builder (`buzz-search`), so the word rule cannot drift from it. The existing full-text index on events stays the access path; the name check runs only on rows the index already matched. There is no new index. One small migration (`0061`) adds the function `profile_name_fields()`; it reads no table data, so it runs instantly. - Only current profiles count: a replaced profile stops matching. Profiles that are not a JSON object, or whose name fields are not strings, never match. Content that PostgreSQL cannot read as `jsonb` (for example a `\^@` escape or very deep nesting) also never matches, and it cannot make the search fail for everyone else. - The handler loads the matched events through the normal routed event read and applies the same reader visibility check as other reads, in search order. - Access uses the same checks as the relay's GIF search endpoint: a signed HTTP request (NIP-98), identity admission (NIP-FI), rate limit, replay protection, and relay membership. That code moved out of `gifs.rs` into one shared helper in `bridge.rs`; GIF behavior is unchanged. - The route is added to the existing protected-route and NIP-FI shadow/enforce route tables. Docs: `docs/profile-search.md`. - Two test-only lines get `sadscan:disable` comments, as other fixtures already do: an existing public ES256 test key in `router.rs`, and the local Postgres test URL in the search integration test. ### Related issue None found. ### Testing - Postgres test for the search query (`profile_names_match_name_words_only`): only name fields match (avatar data URL, `about`, `nip05`, `banner`, non-string names and non-object content are excluded); words in any order and across both name fields; whole words only for completed words; ranking order; pages split without overlap or gaps; replaced profile; other community; `%` literal. - Postgres end-to-end test through the router: an admitted member gets only the name-matching signed event, and the returned event still verifies. - Request validation unit tests; existing GIF admission tests and router route-table tests pass. - Local end-to-end run with buzz-app#1084 against a relay built from this head, with about 195 seeded profiles. For every query tried, the endpoint's results were a subset of the full-text search's results; the only profiles missing were avatar-only matches. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz>	2026-10-15 17:35:33 -04:00
klopez4212	b1d60f98e2	Bring synced Solo chats and projects to mobile (#8337) ... ## Summary Bring desktop Solo chats and project organization to mobile, with synced collapsible sections, shared unread highlights and tab badges, agent selection, shared search, native iOS creation sheets, and inline typing bubbles that transition into replies. Resolve Solo placement for every chat entry route, retain encrypted organization snapshots for offline reading, and let users resume or discard unfinished chat and project setup without deleting existing messages. ### Related issue Related: #6565; expandable agent transcripts remain separate work. ### Testing - Fresh Solo read state seeds each active chat from its captured initial last-message timestamp before exposing row/section/tab unread state. Baselines survive intervening channel updates and reset across identity/community boundaries while surviving read-state readiness changes. Regressions cover multiple chats, events before read-state readiness and during/after seeding, and identity changes; removing either the seed or the display gate fails them. - Chat completion reconciles a retained Solo-save journal even when placement is already confirmed. False/throwing cleanup regressions ensure the outer intent remains until reconciliation and only one placement is published. Typing terminal-close loops remain bounded; the retry budget resets after an uninterrupted eight-second health interval or transport reconnect. - Typing retry budgets reset after sustained recovery; invalid Solo updates retain cached rows with a retry warning that survives failed refreshes. Project names use the editors’ 120-grapheme limit, including emoji and combining characters. Regression coverage exercises repeated recovery, invalid live/refresh heads, and character-limit boundaries. - Rebased onto current main, preserving the newer Search controls, Huddle timeline filtering, and message-media layout. - Failed project journal writes reload storage before claiming recovery and reopen the entered name for retry. Typing subscription rejections are caught; terminal closures clear stale indicators and retry with a bounded backoff, canceled on disposal. Regression tests cover both false/throwing storage writes and initial/late subscription rejection. - Explicit ordinary destinations skip optional Solo lookup waits. Generic destinations perform one bounded lookup in the destination (search no longer duplicates it); an unavailable classification falls back to ordinary sending per the product owner's explicit choice. Positively identified Solo destinations use Solo providers. - Terminal Solo subscription closure preserves cached rows and exposes live-update Retry. Page coverage verifies warning visibility, usable rows during recovery, and a subsequent terminal close. Removing the warning or the immediate ordinary-route guard fails its regression. - Generic channel entries share an ordinary default when Solo classification is unavailable, per the requested product behavior. Known Solo placement takes precedence; callers can explicitly require unresolved placement to remain blocked. Bounded initial lookup preserves known Solo deep-link routing. - Dirty newest snapshots and offline-save warnings survive transport reconnects; Retry persists that same event even if the relay returns an older head. Community changes replace the service, and agent-directory reconnect refresh remains intact. - Pending-save discard reloads failed removals. Repeated reconnect testing confirms typing subscriptions are released on provider rebuild and disposal; removing the existing cleanup fails the regression. - Ordinary Home/create routes explicitly preserve private-channel sending during Solo failures; identified Solo sends use the Solo sender and explicit unresolved routes remain fail-closed. Solo unread replies beyond the initial 200-event page are loaded through the oldest-unread boundary. - Chat/project/agent cleanup reloads failed removals, retains same-process recovery, and protects replaced records. False/throw regressions verify retries do not duplicate creation or membership. Route, unread, and cleanup guard-removal mutations each fail their regression. - Ordinary channels, DMs, and forums remain sendable when optional Solo sync fails; explicit unresolved placement stays blocked. Controlled cache races retain the newest verified snapshot, keep usable chats visible, and retry offline persistence without stale writes. Both protection-removal regressions fail as expected. - Confirmed journal cleanup checks false/throwing removal and exact-record identity. Interrupted agent choices are visible immediately, identify the saved agent, and cover Resume/Later/Discard with accessible name/key-fallback controls. - Notification deep links preserve the contiguous history cursor; same-second messages infer the newest agent consistently. Failed offline-cache writes surface Retry, with false/throwing storage failures and offline restart covered. - Composite history cursors cover 350 same-second events plus older history; removing the ID cursor makes the regression fail. Agent changes now journal before granting access, with restart/failure and Resume/Later/Discard widget coverage. Signed malformed profiles remain isolated. - Native iOS avatar tests passed on the simulator: visible-row loading, three-request concurrency, streamed byte limits, response validation, downsampling/pixel limits, cancellation, and visible avatar updates. - Solo and Home share observed-event/read-marker logic. Widget coverage verifies unread rows, collapsed-section indicators, the tab badge before first Solo visit, message/thread reads, forced unread, and filtering archived/nonmember/unplaced chats. - Chat intent is saved before ownership and organization preflight; tests cover interrupted ownership lookup and a disconnect while the native creation form is open. - Mobile analysis, formatting, file-size checks, and full mobile tests passed at `1d4c41354`. - Project creation persists its encrypted name/UUID before connectivity checks or relay reads. Restart tests cover Resume/Later/Discard, scope isolation, stale-intent rejection, and lost acknowledgements. Removing the pre-network save makes all four production-flow regressions fail. - Regression coverage includes notification/Activity routing, inline replies, unknown-placement send protection, restart recovery/discard, and encrypted offline cache isolation/refresh. - Earlier feature build exercised on a physical iPhone with existing account/community data; review follow-ups have not been reinstalled on the device. UIKit agent-row accessibility checks passed on an iOS simulator. - Earlier cross-platform `just ci` stopped on the existing `buzz-acp` test `signals_cancel_startup_turn_and_pending_stdin_without_hanging` (process exit-code assertion); no Rust production changes are included in this PR. ### Remaining review limitation Agent discovery is bounded to 10 pages / 1,000 profiles with automatic retries disabled. Owner-scoped discovery remains open because the current relay ignores `#auth` filters; supporting that query requires a relay change. ### Snapshots Sample data, shared Flutter/Android surface.

Kalvin C	cdfc38ecbd	feat(search): add newest-first sort to bridge search (#8371) ... ## Summary Adds an opt-in newest-first order to bridge search, so clients can offer "Most recent" alongside relevance. - `buzz-search`: `SearchQuery` gains `sort: SearchSort`. `Relevance` keeps the existing `ts_rank_cd` ordering. `Newest` orders hits by `created_at DESC, id`, and `page` steps through that order. Newest skips the exact-profile-lexeme prioritization, which only applies to relevance ranking. - Bridge `POST /query`: search filters accept `search_sort: "newest"`. When the field is missing or has another value, results stay in relevance order. Community scope, channel intersection and per-hit authorization are unchanged. - NIP-11 lists `buzz-search-sort` in `supported_extensions`. Clients only send the field to relays that advertise it, so they never get relevance results labelled as newest. - WebSocket NIP-50 search stays relevance-only. `NOSTR.md` documents the bridge extension. ### Related issue N/A ### Testing - New Postgres integration test `newest_sort_pages_by_time_then_id_within_scope`. It pages a channel in newest order, including an equal-timestamp tie split across a page boundary and a newer hit outside the channel scope. It checks that the pages join up in `(created_at desc, id asc)` order and that relevance still ranks the strongest match first. - Unit tests: - `bridge_search_sort_extension_selects_newest_only_when_named` - `advertises_nip_cl_and_search_sort_extensions` - Ran the buzz-search Postgres integration suite, the relay `nip11` and `bridge_search` unit tests, `cargo fmt --check`, and `cargo clippy -p buzz-search -p buzz-relay --all-targets -D warnings` on Linux. - Local relay exercised through signed `POST /query`: - NIP-11 lists `buzz-search-sort`. - Relevance and newest return different orders. - Newest pages 1–3 return 25 hits with no gaps or duplicates, including same-second ties across page boundaries. - A non-member gets no hits from a private channel; a member gets all of them. - Client integration is in a companion block/buzz-app change. It was exercised end to end against this relay through the production broker: switching sort, paging, scope changes and capability fallback. Deployment note: clients only offer newest sorting after a relay with this change advertises `buzz-search-sort`. --------- Signed-off-by: Kalvin Chau <kalvin@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-15 13:27:49 -07:00
klopez4212	d61fe2071d	Use native UIKit scrolling for iOS photo carousels (#8361) ... Builds on the mobile polish merged in #8359; this PR now targets `main`. On iOS, inline photo galleries now use a UIKit collection view for dragging, deceleration, and snapping. Photo taps retain the existing full-screen viewer and reply/more actions; gallery scrolling continues to fade the message avatar. The final photo stops at the full message gutter rather than the smaller gap between photos. Android keeps the current Flutter carousel. Visible cells subscribe to continuing frames from Flutter's existing authenticated image providers, preserving animated GIF/APNG/WebP media. Request IDs fence late frames and cancel subscriptions on reuse/disappearance/disposal. A four-slot bound includes retired unresolved loads until their transport terminates. Shared media fetches now use abortable HTTP requests with a 30-second deadline through response-body completion, so stalled requests release their slots without leaving live transports behind; native eager precaching is disabled so it cannot bypass that bound. Frame conversion coalesces to the newest pending frame. Native cells expose photo labels and positions to VoiceOver, support RTL, and preserve the selected photo during resizing. Validation: - Mobile formatting and analysis passed. - Native simulator regression checks passed for geometry, RTL, snapping, taps, frame replacement, cancellation, and resizing. The native CI lane now runs the carousel executable. - Full mobile suite and pre-push gates passed, including two-frame GIF delivery, delayed-provider bounds/cancellation, real HTTP stalled-header/body recovery with four requests maximum, disposal, and unconfigured-push tests. - Signed iPhone Release build of the frame/subscription implementation passed. Physical iPhone testing covered the earlier carousel/gutter revision; the new animation/cancellation changes have local Flutter and native simulator coverage, not a new physical-device journey. Preview-only signing overrides preserve its bundle/Keychain group; production entitlements are unchanged. Local provisioning excludes production push/App Attest capabilities. - Full `just ci` was started but stopped after unrelated Rust/desktop compilation consumed about 5 GB; broad CI is incomplete. Device build required local Xcode 27 workarounds: iOS 16 deployment target and a generated swift-secp256k1 cache compatibility edit. Neither changes repository source. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz>	2026-10-15 13:22:12 -04:00
