fix(channels): make channel connect flow deterministic (#3582)
* fix(channels): make channel connect flow deterministic * make format * fix(channels): apply connect-code before allowed_users on telegram and wechat The bind-bootstrap reorder shipped for slack/dingtalk only. Telegram and WeChat still gate _check_user/allowed_users before connect-code dispatch, so a newly allowlisted-but-unbound user is silently rejected when binding via the browser deep-link / connect-code flow — the same deadlock the PR fixes. - telegram: consume the /start deep-link token before the allowed_users gate. - wechat: handle the /connect code before the allowed_users gate, and defer inbound file extraction + context-token tracking past the gate so blocked senders no longer trigger CDN downloads or token bookkeeping. Adds regression tests for both adapters mirroring the slack/dingtalk coverage. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(channels): enforce single-active-owner invariant at the DB layer _revoke_other_active_owners did a SELECT-then-UPDATE in app code with no row lock or constraint covering active rows. Under READ COMMITTED, two concurrent connect-code consumes for the same (provider, external_account_id, workspace_id) from different owners could each observe "no other active owner" and both commit a connected row, leaving find_connection_by_external_identity nondeterministic. - Add a partial unique index on (provider, external_account_id, workspace_id) WHERE status != 'revoked' (portable to SQLite >= 3.8.0 and PostgreSQL) so the database guarantees at most one non-revoked row per external identity. - Reorder upsert_connection to revoke other owners' active rows before the new connected row is flushed (so the index is satisfied at commit), wrapped in a bounded rollback-and-retry loop. A losing concurrent writer now retries against the now-visible state instead of committing a duplicate. Adds DB-constraint, revoked-slot-reuse, and concurrent-upsert regression tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(channels): harden connect-status polling primitive pollChannelConnectionUntilResolved was a free-floating recursive setTimeout started from onSuccess with no cancellation, no per-provider dedup, a redundant second endpoint per tick, and an unbounded loop on a non-finite expires_in. - Extract a framework-agnostic, cancellable poller (connect-poll.ts) that polls only listChannelConnections() and invalidates the providers query once when the bind resolves, instead of fetching both endpoints every tick. - Guard expires_in with a finite check + default window so undefined/NaN can no longer produce a poll loop that runs until the page closes. - Track one active poll handle per provider in useConnectChannelProvider via a ref Map: a new connect cancels the prior poll for that provider, and a useEffect cleanup cancels all polls on unmount. Adds unit tests for resolve-and-stop, cancellation, and non-finite-expiry. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(channels): stop leaking blocked-sender content in DingTalk INFO log; document bind semantics Moving the allowed_users gate past _extract_text meant the parsed-message INFO log (text=%r, first 100 chars) fired for senders that allowed_users would have rejected, defeating the filter's noise/privacy role. Move that log to after the allowed_users gate so blocked senders' message text never reaches INFO logs. Also document the two operator-relevant semantic changes in backend/CLAUDE.md: connect-code dispatch runs before allowed_users (so allowed_users is no longer a bind-time defense; the model relies on code confidentiality + 600s TTL + one-time consumption), and the single-active-owner-per-external-identity transfer semantics now backed by the partial unique index. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(channels): note connect-code-vs-allowlist and ownership transfer in operator guide Mirror the backend/CLAUDE.md notes in the operator-facing IM_CHANNEL_CONNECTIONS.md: connect codes are consumed before allowed_users (so a not-yet-allowlisted user can still complete a first bind, and allowed_users is not a bind-time defense), and an external identity has at most one active owner with last-bind-wins transfer enforced at the DB layer. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * refactor(channels): lift connect-code dispatch into Channel base class Each adapter duplicated the ordering-sensitive boilerplate of extracting a /connect code and guarding on the connection repo before its allowed_users gate. The duplication is what let telegram/wechat drift and keep the gate ahead of the bind. Centralize it: - Move `_connection_repo` onto Channel.__init__ (removing 7 duplicate assignments). - Add Channel._pending_connect_code(text), which guards on the repo and extracts the code, documenting that adapters MUST consult it before authorization so a browser-initiated bind can bootstrap a not-yet-authorized identity. - Route slack, discord, feishu, dingtalk, wechat, and wecom through the helper. This also fixes a latent inconsistency where slack dispatched a bind even when no connection repo was configured. Pure refactor — the full channel suite stays green; adds a direct unit test for the base helper's contract. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * make format * fix(channels): redact DingTalk parsed-message INFO log content Log text_len instead of the first 100 chars of message text, so message content never reaches INFO logs (the after-gate move already keeps blocked senders out entirely). This takes over the redaction from #3584 so only this PR touches dingtalk.py, letting the two PRs merge in any order conflict-free.
