Keep admin reads correct across moves, aging and request cancellation - #600
Priority aging and lane moves could make job reads match a tombstoned source row or miss a retained terminal body. Reads now match the exact attempt by job ID and run lease, exclude moved source rows, and select one live body. The fix covers materialized leases, legacy row-local receipts and default compact receipts without multiplying current-job projections.
Job-detail reads use one read-only repeatable-read transaction. They acquire ACCESS SHARE on the ready, lease and claim rings before the first data query, fencing concurrent partition truncation and failed-row carry. Cancelled or failed BEGIN acknowledgements close the connection, so later callers cannot inherit an untracked transaction; acknowledged transactions retain normal rollback and connection reuse.
New terminal writes retain the physical ready-lane priority. Rust reads, manual retry and failed-row carry also recover older narrow rows through the retained attempt. Ready metadata supplies defaults while stored terminal overrides, errors, tags and progress remain authoritative. Counter removal uses the stored terminal lane; carried replacement counters use the inserted lane. Manual terminal retry restarts aging from the physical lane, and manual terminal-to-DLQ moves retain that lane for later DLQ retry. Automatic retryable rescue and automatic DLQ routing retain effective aged priority.
The branch also includes #642: a lock timeout anywhere in prune or terminal rollup rolls back the attempt and reports Blocked, and rollup stops at the first blocked slot.
Costs and limits:
Hydration probes only referenced ready-slot tombstone children. Legacy terminal retry and admin mutations reference the tombstone parent and its partitions, adding ACCESS SHARE locks. A combined release-line PG18.6 control measured 66 additional relation-mode entries for terminal retry, single/bulk manual DLQ moves and discard; this is not a measurement of main's full transaction footprint.
No migration, additional query round trip or new strong lock is added by the terminal-body fix. The installed terminal_jobs view is unchanged for older mismatched-priority rows; already-pruned backing bodies cannot be reconstructed.
Validation:
Twenty focused terminal-body cases pass on PostgreSQL 17 and 18, including the shared aged-and-moved single/bulk DLQ and discard fixture, physical-priority retry, metadata provenance and exact counter removal.
Release-line old-model controls independently reproduce body loss, metadata loss and both manual DLQ priority failures; same-lease cancellation remains valid.
Both Rust workspaces pass formatting, all-target/all-feature Clippy with warnings denied, and workspace builds.
Existing cancellation/reuse, admin equivalence and real prune-race controls are retained. Their earlier validation covers PostgreSQL 17/18.
A release-line actual bulk API comparison preserved all 10,000 IDs/bodies on both versions. The candidate's hydration plan used 50,408 shared-buffer hits versus 20,671 on v0.6.13, with no disk reads or temporary buffers. Whole-API times were 0.315s versus 0.292s in one instrumented run; this does not establish a latency or throughput result.
Summary by CodeRabbit
Bug Fixes
Improved job lookups and administrative listings for jobs whose priorities have aged, including callback reads, counts, and unique-key cancellation.
Point reads now exclude jobs that have moved during queue rotation, and job details are read consistently.
Manual retries preserve job bodies, and lane moves return current queue and priority values.
Cancelled or failed transaction starts no longer leave connections in an unusable state.
Queue pruning and terminal-count rollups handle lock timeouts without partial changes; rollups stop at the first blocked item.
Claims and leases record the aged effective priority while the ready row
keeps the lane priority. load_job, load_active_lease_in_tx and
callback_job_in_tx joined the two on priority, so with priority aging on a
job that had aged before its claim could not be found by callback or read
back as running. Match the attempt by job_id and run_lease instead.
load_job also read its seven relations in separate autocommit statements,
so a job moving between two of them could read as missing, as the weekly
mixed-version rehearsal saw. Read them from one REPEATABLE READ, READ ONLY
snapshot.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Queue reads now use guarded transactions and match running attempts by job and run lease. Terminal operations recover ready-body data and lane priority. Prune and terminal-delta rollup transactions roll back on lock contention and report blocked outcomes.
BeginGuard owns the connection while transaction startup is pending. Admin reads use the guard. Integration tests check cancellation cleanup and connection reuse.

Reads and recovery of aged jobs are mostly fixed. One window remains where a job claimed just before priority aging moves its row can fail rescue or disappear from a point read. Aged terminal retries can still lose their original payload on some paths, and the original priority is displayed incorrectly for aged leases. Resolve the claimed-row hydration gap before merging, or explicitly accept it.

A rabbit checks the queue at dawn It finds the live lane, not the gone When locks delay the careful sweep The rows roll back, their counts they keep Then retries hop along their way
… on a lock
Prune and terminal-count rollup set a transaction-local lock_timeout before
taking ACCESS EXCLUSIVE on a slot's partitions, but only the LOCK TABLE and
TRUNCATE steps mapped a timeout to Blocked. The timeout also applies to the
statements after them: the post-lock liveness checks over the lease and claim
partitions, the failed-row carry into the current slot's done_entries and
terminal-count deltas, the rollup delta append and the live-counter cleanup.
A wait there surfaced as a 55P03 database error, was logged as a prune error
and skipped the prune backoff.
Run everything after the timeout is set as one block and settle it in one
place: commit on success, and on a lock timeout from any statement roll back
and report Blocked. Lease and claim prune use the same helper so the rule
holds for every ring. The commit duration in PruneDurations is still measured
around the commit.
The new tests hold a SHARE lock on each relation the queue prune writes after
its child locks, and on queue_terminal_live_counts for the rollup; both fail
with 55P03 before this change.
…ocked slot
The remaining sealed slots would most likely wait out the same lock timeout,
and with a raised prune timeout that holds the maintenance leader for one
timeout per slot. The rollup test now seals two slots with pending deltas and
expects one blocked slot, then both rolled once the lock is released.
Rust prune tests (AlloyDB Omni) failed on 04232c00 (run 42202477827): test_queue_storage_prune_waits_until_ready_tombstone_cursor_spent got 55P03 canceling statement due to lock timeout from the second prune_oldest, after the test's own reader had rolled back.
The test never calls load_job or the admin reads. It only enqueues, tombstones, rotates, claims and prunes.
Each test gets its own database, so another test's locks can't reach it.
On 3dca751e a different prune test failed the same way: Blocked instead of Pruned. Both failures are lock timeouts on AlloyDB only.
The prune tests pass on PG16 locally (3×), and main's AlloyDB job passed on 695acaa5 and 84ab0505.
My guess is that AlloyDB's background workers briefly contend for the new partition's locks. I haven't confirmed that.
Main's prune_oldest also returns a raw Err for a lock timeout here instead of Blocked; 0.6's #641 fixes that. Porting it wouldn't make this test pass, since it would then see Blocked instead of Pruned. No fix exists yet. I'll re-run the failed job once this run finishes.
Preserve the aged/current-row read fixes while incorporating the reviewed
transaction-wide prune rollback and first-blocked-rollup behavior from #642.
The AlloyDB CI failure waited on queue_terminal_live_counts after the child
locks; that timeout now returns Blocked with the whole attempt rolled back.
Validation: cargo fmt --all; offline all-target/all-feature Clippy with
warnings denied; offline workspace build; 28 prune tests and the late-lock
rollup regression pass on PostgreSQL 17, PostgreSQL 18 and AlloyDB Omni 18.3.

Real, and it predates this PR. hydrate_deleted_leases_tx writes the lease's effective priority into the transition and done rows, and every way back to the ready row's args and max_attempts joins on priority (done_ready_join for retry_job, the terminal_jobs view, the failed-row carry). On main the trigger is heartbeat, deadline or callback-timeout rescue, or admin cancel, of an aged lease: a later retry re-enqueues {} with max_attempts 25. This PR adds resolve_callback Fail as one more way in. The likely fix is for hydrate to select ready.priority and write the lane priority, as the worker path does. That changes what every rescue path writes, though, so I'd rather it got its own PR with its own tests than widen this one. Leaving this open for the maintainer's call.
The reason will be displayed to describe this comment to others. Learn more.
@hardbyte Thanks for the analysis. A separate PR makes sense given the effect on rescue paths. The finding remains open for the maintainer’s call.
The follow-up should test that retry and failed-row retention preserve the original arguments and max_attempts.
Would you like me to open a GitHub issue for the follow-up?

Learning: Within repository "hardbyte/awa", only for files matching one of ["awa-model/src/queue_storage.rs"]: When reviewing ready-backed terminal writes or reads in awa-model/src/queue_storage.rs, check that an aged attempt whose effective priority differs from its ready lane priority still identifies the correct backing ready row. Verify that terminal reads, failed-row retention carry, and subsequent retry preserve the original arguments and max_attempts; do not assume effective-priority equality identifies the ready row.

… get_job
Aging and lane moves tombstone a ready row and re-insert the same attempt on
another lane. In a quiet queue the new lane can hand out the old lane_seq, so
a lease or claim joined to its ready row by job_id and run_lease matched both
rows: admin job lists and kind counts showed the running job twice. Every
attempt join now excludes tombstoned ready rows. The legacy row-local claim
join in the admin current-jobs read matched on priority and now matches the
attempt too.
get_job reads from one REPEATABLE READ snapshot, but TRUNCATE is not
MVCC-safe: a claim or lease partition that prune empties after the snapshot
reads as empty while the completion that allowed the prune is newer than the
snapshot, so a finished job could read as available. get_job now takes
ACCESS SHARE on the lease and claim rings, in claim prune's order, before its
first query; prune waits for the read or times out to Blocked.
The CHANGELOG limits the lock-timeout-to-Blocked guarantee to statements after
prune sets its lock_timeout.

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
A query takes its snapshot before it locks the relations it reads, so a
queue prune could truncate a ready, done or receipt-completion partition
after get_job's snapshot but before its first query locked that partition.
The job would then read as available or missing. Take ACCESS SHARE on
ready_entries in the same LOCK TABLE as the lease and claim rings, which
takes no snapshot. Queue prune locks its ready child with NOWAIT ahead of
the done and receipt-completion children, so it reports Blocked.
Once the test releases its own locks, a hosted Postgres background worker
can still briefly hold a partition; AlloyDB Omni reported Blocked on the
final prune. Retry Blocked within a scaled five-second bound, and count
rolled slots across rollup attempts. Any error or other outcome still fails.

Hydrate the live ready row for the deleted attempt.
When a moved job’s source and destination share a position, hydrate_deleted_leases_tx can select the tombstoned source. A terminal row can then retain the source priority and lose the destination’s _awa_original_priority metadata. Retrying a cancelled or failed job can re-enqueue it at the pre-move priority.
Match the ready row by run lease and exclude tombstoned rows. Preserve attempt identity when building the map. Add coverage that transitions and retries a shared-position moved attempt.

- Around line 12454-12464: Update age_waiting_priorities to lock claim heads
before checking claim evidence so rows claimed before cursor advancement are not
aged; also add an exact-attempt hydration path in hydrate_deleted_leases_tx for
claimed bodies already tombstoned, matching the claimed attempt without relying
on destination lane sequence or shard. Preserve existing hydration safeguards
and ensure load_job can still include the running attempt.

A claim can commit before its cursor advances. During that interval, age_waiting_priorities can tombstone the claimed row. If the destination row has a different lane sequence or shard, hydrate_deleted_leases_tx cannot match it. Rescue can then fail with “ready row missing for deleted lease”, and load_job can omit the running attempt.
Prevent aging from moving claimed rows by locking claim heads before checking claim evidence. Also preserve an exact-attempt hydration path for claimed bodies that were already tombstoned.

Priority aging and lane moves could make job reads match a tombstoned source row or miss a retained terminal body. Reads now match the exact attempt by job ID and run lease, exclude moved source rows, and select one live body. The fix covers materialized leases, legacy row-local receipts and default compact receipts without multiplying current-job projections.
Job-detail reads use one read-only repeatable-read transaction. They acquire ACCESS SHARE on the ready, lease and claim rings before the first data query, fencing concurrent partition truncation and failed-row carry. Cancelled or failed BEGIN acknowledgements close the connection, so later callers cannot inherit an untracked transaction; acknowledged transactions retain normal rollback and connection reuse.
New terminal writes retain the physical ready-lane priority. Rust reads, manual retry and failed-row carry also recover older narrow rows through the retained attempt. Ready metadata supplies defaults while stored terminal overrides, errors, tags and progress remain authoritative. Counter removal uses the stored terminal lane; carried replacement counters use the inserted lane. Manual terminal retry restarts aging from the physical lane, and manual terminal-to-DLQ moves retain that lane for later DLQ retry. Automatic retryable rescue and automatic DLQ routing retain effective aged priority.
The branch also includes #642: a lock timeout anywhere in prune or terminal rollup rolls back the attempt and reports Blocked, and rollup stops at the first blocked slot.
