hugocasa ee3d82f01f fix(native-triggers): serialize Google channel renewal across replicas (#9060)
* fix(native-triggers): serialize Google channel renewal across replicas

`sync_all_triggers` runs every 5 minutes on every windmill-app replica
with no leader election. Multiple replicas were each rotating the
webhook token, creating a new Google watch channel, and racing the
trigger UPDATE — leaving the loser's new token (in `token`) and channel
(in Google) orphaned. Cloud was accumulating ~5 leaked tokens/week
without the silent best-effort `delete_token_by_hash` ever logging a
warning.

Wrap each per-trigger renewal in a transaction and acquire the row with
`SELECT … FOR UPDATE SKIP LOCKED`. Contending replicas skip the row
instead of duplicating the work. The lock spans `rotate_webhook_token`
→ Google API call → `update_native_trigger_service_config` and is only
released on commit. Re-checks `should_renew_channel` after acquiring
the lock so a replica that committed seconds earlier doesn't trigger a
duplicate renewal.

The pattern matches existing batch-cleanup paths in `monitor.rs`
(job-retention sweep) and other `FOR UPDATE SKIP LOCKED` call sites.

Also logs at `debug!` when `delete_token_by_hash` finds no matching row,
so future investigations can distinguish "deleted" from "not found"
without changing the `Ok(false)` contract.

fixup! fix(native-triggers): serialize Google channel renewal across replicas

Address claude review:
- #5: per-skip log info -> debug (expected outcome under SKIP LOCKED)
- #2: warn moved out of delete_token_by_hash to the call site that knows the
  expected state (try_renew_channel_locked); other callers are race-prone and
  shouldn't warn
- #3: NULL service_config now warns (anomalous case)
- #4: post-Google-API DB-update + commit failures log distinctly so the
  channel-orphan case is grep-able

Plus: add 14d expiry to Google webhook tokens via ServiceName::webhook_token_expiration,
mint fresh ephemeral-webhook-{service}-{rd5} labels at create + rotate so the
existing 'ephemeral-' filter excludes them from user-token email/critical-alert
paths (no filter changes in 3 places). Orphans now self-clean via the existing
expiry sweep in monitor.rs.

fixup! fix(native-triggers): serialize Google channel renewal across replicas

Address second-round review:
- Claude #1 (P2): username_override_from_label now strips the 'ephemeral-'
  prefix for ephemeral-webhook-* labels, so created_by stays
  webhook-{service}-{rd5} instead of changing to label-ephemeral-webhook-...
  (preserves audit/job-list filter compatibility)
- Codex (P2): updated renew_channel doc — labels are no longer copied; rotate
  mints fresh ephemeral-webhook-google-{rd5} with 14d expiration
- Claude #3 (optional): test_rotate_webhook_token now asserts the rotated
  Google token has an ephemeral-webhook-google-* label and a populated
  expiration

fixup! fix(native-triggers): serialize Google channel renewal across replicas

Reconsider the previous fixup: stripping the 'ephemeral-' prefix made
created_by no longer match token.label exactly, defeating the linking
purpose. Just allowlist 'ephemeral-webhook-' alongside the other
recognized webhook/email/ws prefixes — created_by becomes
ephemeral-webhook-google-XXXXX, matching token.label exactly. The
'ephemeral-' substring also informs operators that this is a
system-managed auto-expiring token vs a user-managed webhook trigger.

Ruben Fiszel f2be625348 feat: store hashed tokens instead of plaintext (#8217)
* feat: store hashed tokens in the token table instead of plaintext

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: address review issues in token hash migration

- Update all base.sql fixtures to include token_hash/token_prefix columns
- Keep plaintext token for webhook tokens (needed for URL reconstruction)
- Restore get_token_by_prefix to query DB for webhook tokens
- Fix down migration to delete NULL-token rows before restoring NOT NULL
- Update parser fixture standalone schema
- Update EE dedicated_worker_ee.rs to use token_hash/token_prefix

* fix: restore sqlx offline cache (only add new query files)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: keep writing plaintext token column for backward compat

Write to token column alongside token_hash until MIN_VERSION_SUPPORTS_TOKEN_HASH
(1.649.0) is reached. This ensures older workers can still authenticate
during rolling upgrades. Remove the separate UPDATE in new_webhook_token
since create_token_internal now writes plaintext directly.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: branch on MIN_VERSION to write plaintext token or null

Check MIN_VERSION_SUPPORTS_TOKEN_HASH at runtime: write plaintext to
token column while old workers exist, switch to NULL once all workers
are >= 1.649.0.

* fix: prevent panic on short superadmin secret token prefix

Replace all `token[0..TOKEN_PREFIX_LEN]` slicing with
`token.get(..TOKEN_PREFIX_LEN).unwrap_or(token)` to prevent
panics when a token shorter than 10 chars is provided (e.g.
malformed Authorization header, short superadmin secret).

* update dates and version

* updat ee ref + sqlx

* improve mcp migration

* fix: atomic token rotation with rollback on trigger update failure

rotate_webhook_token now atomically inserts the new token and deletes
the old one in a single transaction, preventing token leaks.

Returns new_token_hash so callers can clean up the new token if their
subsequent trigger update fails (which involves external HTTP calls
and cannot be in the same DB transaction).

- Handler: wraps post-rotation work; deletes new token on failure
- Google renewal: deletes new token if service_config update fails
- Tests updated to match new atomic semantics

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* higher min version

* fix: defer old token deletion to avoid breaking triggers on update failure

rotate_webhook_token now keeps the old token alive and returns
old_token_hash. Callers delete it only after the trigger row has been
successfully updated. If the external service call or DB update fails,
the trigger keeps working with the old token.

Worst case: if the best-effort delete fails, the old token leaks as an
extra DB row — harmless compared to breaking the trigger.

Also update summarized_schema.txt for renamed columns.

* fix: prevent panic on short tokens by using safe prefix extraction

Add safe_token_prefix() helper that uses .get(..TOKEN_PREFIX_LEN).unwrap_or(token)
instead of direct slice indexing, preventing panics when tokens are shorter than
10 characters (e.g., short superadmin secrets or malformed Bearer tokens).
