From 1c8f48fd77ad57fdef9e5516b9d1b6dbd97a5a2a Mon Sep 17 00:00:00 2001 From: "Abiba (pi)" Date: Fri, 26 Jun 2026 22:23:38 +0000 Subject: [PATCH] =?UTF-8?q?feat(hermes):=20Zulip=20adapter=20Gen=202=20?= =?UTF-8?q?=E2=80=94=20dedup=20cleanup=20task,=20self-test,=20health=20sta?= =?UTF-8?q?ts,=20dynamic=20all-bots?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Gen 2 improvements from build-zulip-plugin contract run: 1. Background dedup maintenance task - _dedup_cleanup_forever() runs every 120s, pruning stale entries - _is_duplicate() is now pure O(1) — no per-call cleanup overhead - Cleanup is cancelled gracefully on disconnect 2. Self-test diagnostics (selftest()) - 8 checks: connection, queue, HTTP client, bot identity, poll loop, dedup cleanup, echo prevention, @all-bots configuration - Returns structured verdict: healthy / degraded / critical_failure - Verifies every Success Criterion from the contract 3. Health stats tracking (get_health_stats()) - Uptime, poll counts/errors, message routing counts, send stats - Error rate computation, dedup map size - Suitable for periodic RA-H OS knowledge graph logging 4. Dynamic @all-bots resolution - _resolve_all_bots_user_id() queries Zulip /api/v1/users on connect - Falls back to configured env var or hardcoded default (1) - Eliminates fragile hardcoded default in multi-bot deployments 5. Connection lifecycle now manages both poll_task and dedup_cleanup_task - Both cancelled gracefully on disconnect() - dedup task starts in connect() after queue registration --- PR21-REVIEW.md | 105 ++++++++ plugins/platforms/zulip/adapter.py | 394 ++++++++++++++++++++++++++--- 2 files changed, 470 insertions(+), 29 deletions(-) create mode 100644 PR21-REVIEW.md diff --git a/PR21-REVIEW.md b/PR21-REVIEW.md new file mode 100644 index 0000000..56ad602 --- /dev/null +++ b/PR21-REVIEW.md @@ -0,0 +1,105 @@ +# PR #21 Review — fix(tanko): adapter fixes, event logging, platform-based deploy.sh + +Reviewer: Abiba +Date: 2026-06-20 +Status: ✅ Approve with changes (3 blocking, 3 advisory) + +--- + +## Review Comments + +### Comment 1 (🔴 Blocking): CI stuck at "Waiting to run" + +The Gitea Actions workflow (run #4) hasn't started.
