- Tighten recovery guard to the idempotent drop-then-create shape (require
both DROP and CREATE INDEX CONCURRENTLY). A bare CREATE (20260511000000) is
now refused by gate, deterministically — matching its documented fail-loud
intent instead of relying on the CREATE erroring by accident. Reconciles
README with the committed migration + migration-sql.spec.ts.
- Escape single quotes in print_manual_recovery so the printed escape-hatch
commands are copy-pasteable for SQL containing quotes (e.g. the full-state
WHERE op_type IN ('SYNC_IMPORT', ...) migration).
- Fix MIGRATE_LOG temp-file leak across retry attempts.
- Add an in-script per-step timeout (with_timeout) so the Dockerfile CMD /
helm initContainer paths (no outer timeout) can't hang forever on a blocked
concurrent build; 124 fails loudly.
- Harden parse_failing_migration: sentence-anchored P3009 parse + reject
names outside the migration charset (path-traversal defence).
- Gate also accepts SQLSTATE 25001 (stable Postgres contract) not just the
localizable English message.
- MAX_ATTEMPTS -> documented tight bound (6); fail_loudly wording fixed
(was contradictory for the non-CONCURRENTLY case).
- Tests: bare-CREATE refusal, P3009 decoy-token parser hardening; trim
migration-sql.spec.ts to the architectural-invariant subset (no hardcoded
names) per 'test behavior not implementation'.
Full server suite: 36 files, 727 passed / 5 skipped.
prisma migrate deploy wraps each migration in a transaction; CONCURRENTLY
index migrations fail it (P3018/25001) and later deploys then stick (P3009).
Recovery was duplicated and migration-name-hardcoded in the host deploy.sh
and the in-image migrate-deploy.sh. The host script self-updates only via a
best-effort git pull, so a stale host deploy.sh had no recovery branch for a
new CONCURRENTLY migration and failed the deploy (the reported incident).
- migrate-deploy.sh: single, name-agnostic recovery. Parses the failing
migration from Prisma's own output, gates on the txn-block/P3009 signature
AND the migration's own SQL containing INDEX CONCURRENTLY, runs that SQL
out-of-band statement-by-statement, and only marks it applied if every
statement succeeded; otherwise fails loudly with manual steps. Bounded
retry loop; aborts instead of looping on re-failure.
- deploy.sh: ~290 lines of hardcoded host-side recovery removed; now invokes
the in-image scripts/migrate-deploy.sh (always version-locked to
prisma/migrations in the pulled image) and keeps only timeout/exit policy.
- tests: drive the script end-to-end via a fake npx (P3018, stuck P3009,
non-CONCURRENTLY refusal, statement-failure, re-failure abort, genuine
error passthrough, multi-migration chain); migration-sql.spec.ts updated
to the new contract.
- prisma/migrations/README.md: authoring rules the recovery relies on.
Design: docs/plans/2026-05-15-generic-concurrently-migration-recovery-design.md
* docs(sync): add super sync server perf plan
* perf(sync): implement supersync server perf phases
* fix(sync): bracket auth cache invalidation
* fix(sync): avoid empty replay state stringify
* fix(sync): harden supersync batch uploads
* fix super sync review findings
* fix(sync): guard payload bytes backfill rollout
* perf(sync): speed up payload_bytes backfill and index its scan
Raise the backfill batch size (DEFAULT 5->500, MAX 25->1000) so a
100M-row operations table backfills in minutes rather than tens of
hours. Add a CONCURRENTLY partial index on (user_id, id) WHERE
payload_bytes = 0: it drains to empty post-backfill so the boot-time
backfill self-check and the BOOL_OR quota probe stop doing a full
sequential scan to prove absence, and it makes the backfill's per-user
keyset paging a true index seek. Wire the new concurrent-index
migration into both deploy scripts' P3018 recovery path. Add
migration-SQL guard tests for the ADD COLUMN (metadata-only fast path)
and the new partial index.
* fix(sync): bound auth cache invalidation map and bracket every delete
The auth verification cache's invalidationVersions map grew one entry
per lifetime-invalidated user with no eviction (unbounded heap on a
long-lived single replica). Cap it at the same 10k LRU bound as the
entries map, re-inserting the just-invalidated user at the MRU tail so
the CAS race protection still holds for the only window that matters
(one DB round trip). Bracket the passkey/magic-link registration
cleanup deletes with pre+post invalidate to match the documented
convention, and invalidate on verifyEmail so a freshly-verified user
isn't denied for up to the cache TTL.
* perf(sync): skip the redundant exact replay-state measurement
The delta accounting is a proven over-estimate of the serialized state
size, so when the running bound stays within the cap the true size is
too and the final exact JSON.stringify is provably redundant. Skip it
in that case (still measure-and-throw whenever the bound does not prove
safety). This collapses the common small/incremental replay back to
zero expensive full stringifications, matching the old per-op loop
instead of regressing it. Name the entity-key JSON overhead constant
and document that assertReplayStateSize's return value is load-bearing.
* refactor(sync): split processOperationBatch into pipeline stages
Extract the 297-line batch upload method into a thin orchestrator plus
six named single-responsibility stage helpers (validate+clamp, intra-
batch dedupe, classify existing duplicates, conflict-detect, reserve
seq + insert, full-state clock). Behavior-preserving: every stage
writes terminal rejections into the shared results array by index and
the two empty-set guards short-circuit exactly as before. Also share
the timestamp clamp, the duplicate-op SELECT, and the merged
full-state clock persistence between the batch and legacy paths so
they cannot silently diverge.
* test(sync): pin batch error-code divergence and aggregate-once
Strengthen the intra-batch duplicate test to assert same-id /
different-content yields DUPLICATE_OPERATION (deliberate divergence
from the legacy INVALID_OP_ID), and document the divergence in the
plan. Replace the single-full-state aggregate test with two
full-state ops + a spy asserting _aggregatePriorVectorClock runs
exactly once and last-write-wins — the old test could not catch a
per-op-aggregate regression. Add a makeOp fixture factory. Correct
the plan's overstated replay-stringification numbers.
