fix(queue-storage): create queue lanes as the schema owner (v053) - #637
A queue lane’s enqueue and claim sequences belonged to whichever role first touched it. Other runtime roles could then fail with permission denied for sequence, and a runtime without schema CREATE could not create a missing lane.
Migration v053 installs schema-owner SECURITY DEFINER provisioners in every trusted queue-storage schema. New sequences mirror privileges from their head tables, so runtime roles can share lanes without relying on the creator’s default privileges. Provisioning retains the existing lane advisory lock, helper signatures and cursor semantics. New binaries fall back to the existing path before the helpers are installed; old callers use the refreshed helpers after migration.
Existing sequences are repaired after the migration commits, one sequence per transaction with a 300 ms lock wait. Busy or unauthorized sequences remain reported rather than failing the completed migration. awa storage lane-sequences [--schema S] [--repair] checks or repairs them and exits 2 while problems remain. External SQL migration runners install v053 before running that diagnostic and repair step.
The repair also supports a migrator whose schema-owner membership permits SET ROLE without inheritance. It transfers ownership, temporarily assumes the new owner only when grants require it, and restores the exact previous role. It does not require inherited privileges from the new owner. Repair remains invoker-authorized, with public execution revoked and transaction rollback on a lock timeout. Database-role, upgrade and CLI guidance describe these requirements.
Validation at cacf3809:
Independent Standards and Spec follow-up reviews found no new actionable issues after integrating main 27a59231 and preserving its worker/admin fixes.
Root and Python Rust workspaces pass formatting, all-target/all-feature Clippy with warnings denied, and workspace builds.
PostgreSQL 17 and 18 each pass the new SET-only regression and six focused ownership, mixed-fleet and deploy-order controls: 14 exact passing cases. All owned test resources were removed.
With only the repair SQL reverted and the regression unchanged, both matched PostgreSQL engines fail because the SET-only migrator is absent from repair_roles. The fix passes the full ownership, grant, runtime-use and role-restoration assertions.
Fresh full CI is pending on this head. Earlier full-suite results are historical evidence; they do not certify this integration.
The 0.6 counterpart uses the separate definer_lane_provisioning schema patch in #638.
A lane's enqueue and claim sequences were created by whichever role first
touched the lane, through SECURITY INVOKER helpers, so only that role and
the roles its default privileges named could use them. Another runtime
role then failed with "permission denied for sequence" on enqueue, claim
or promotion.
Each queue-storage schema now has two SECURITY DEFINER functions owned by
the schema owner, provision_lane and provision_lane_sequences. The lane
helpers create a missing sequence through them, and each new sequence gets
the privileges of the head table it backs. ensure_lane_inserts calls
provision_lane when it exists and is executable, inside a savepoint, and
otherwise writes the lane rows as before.
v053 refreshes the helpers and repairs existing lane sequences one at a
time, reassigning and granting only what the migrating role may and
reporting the rest. awa.lane_sequence_problems and the new
`awa storage lane-sequences` command list what remains with the statements
to run; awa.repair_lane_sequences and `--repair` rerun the repair.
Migration v053 adds schema-owner lane provisioning and sequence repair. Runtime lane creation uses the provisioning function when available and falls back to direct inserts otherwise. New CLI commands inspect or repair lane sequences and report remaining issues.

Summary
Install lane provisioning helpers awa-model/migrations/v023_install_queue_storage_substrate.sql, awa-model/migrations/v053_definer_lane_provisioning.sql, awa-model/src/migrations.rs
The migration installs schema-owner functions to create lanes and sequences, updates sequence-helper fallbacks, and registers migration v053.
Use provisioning during lane creation awa-model/src/queue_storage.rs, awa-model/tests/least_privilege_runtime_test.rs, awa/tests/fixtures/v052_lane_sequence_helpers.sql, awa/tests/lane_ownership_roles_test.rs
QueueStorage calls the provisioning function when available and falls back to direct inserts when it is unavailable. Tests cover runtime access, legacy helpers, concurrency, and lane creation.
Diagnose and repair existing sequences awa-model/migrations/v023_install_queue_storage_substrate.sql, awa-model/src/migrations.rs, awa-model/src/storage.rs, awa/tests/lane_ownership_roles_test.rs
SQL and Rust operations report sequence ownership and grant problems and attempt repairs. Migrations run repair after commit and log remaining issues without failing the migration.

Avoid repairing all live sequences in one migration transaction
When v053 runs against active lanes that need ownership repair, this call performs every ALTER SEQUENCE ... OWNER inside the migration transaction, so each acquired ACCESS EXCLUSIVE lock remains held while later sequences are processed. A concurrent multi-lane enqueue can already hold a later sequence lock and then request an earlier one in its queue-sorted order, while the repair visits sequences in hashed-name order and does the inverse; PostgreSQL then aborts either the migration or the user transaction as a deadlock. Defer ownership repair outside the atomic migration, require a quiesced window, or establish a lock order shared with runtime reservations rather than treating this as rolling-safe.
The reason will be displayed to describe this comment to others. Learn more.
Link the tracking issue from the v053 migration header
The new migration header describes compatibility but contains no issue link. This repository explicitly requires every new vNNN migration header to link its issue, so add the relevant tracking URL or issue reference here; commit or PR metadata is not preserved when operators extract the standalone migration SQL.
…vision_lane
Queue storage takes any queue name, including an empty one, and any smallint priority, so the provisioning functions only reject a null argument or a shard outside 0-63.
…ded lock wait
v053 reassigned lane sequences inside the migration transaction. ALTER
SEQUENCE ... OWNER takes the sequence's ACCESS EXCLUSIVE lock until commit,
with no lock_timeout, so an open enqueue on one lane could stall the whole
migration and every repaired lane waited for the upgrade to commit.
v053 now only refreshes the helpers. After it commits, awa migrate repairs
each lane sequence with its own statement through
awa.repair_lane_sequence(schema, sequence), which has lock_timeout = 300ms;
on 55P03 the sequence is left unchanged and reported as busy. `awa storage
lane-sequences --repair` uses the same path, and the set-returning
awa.repair_lane_sequences(schema) is gone.
Reassigning needs the current owner's privileges, which the schema owner
lacks for sequences the migration role or an app role created. A migration
role connected with role set to the owner therefore could not reassign its
own sequences. The repair now retries such a sequence as the login role,
lane_sequence_problems reports repair_roles (the login roles that can repair
each sequence), and leftovers are reported with the next step to take. The
docs state which role to run the repair as.
Test fresh provisioning without sequence defaults.
Revoke the owner’s sequence default privileges before creating a fresh lane, while retaining the head-table grants. Verify that runtime roles can enqueue and claim. The current defaults can hide removal of the explicit grant loop.

- Around line 581-585: Update the repair flow using REPAIR_LANE_SEQUENCE_SQL so
a 42501 permission failure retries the repair as the login role when it differs

the current behavior for other errors and when the roles are the same.
- Around line 581-585: Before executing REPAIR_LANE_SEQUENCE_SQL to obtain a
LaneSequenceRepair, reject connections that are already inside a transaction;
ensure the repair runs only on an autocommit connection so its sequence locks
are released when the repair completes.
- Around line 590-595: Update the retry flow around
repair_lane_sequence_as_login_role so that, after the login-role retry, any
remaining grants are repaired again using the restored effective role. Preserve
the existing retry behavior and only run the additional repair when grants

Review comments at @awa/tests/lane_ownership_roles_test.rs:
- Around line 79-83: Update the database and role setup around the CREATE

errors or assertion panics, not only on the normal teardown path. Reuse an
established test cleanup mechanism that can safely remove partially created
resources, including when the test unwinds.
Review comments at @CHANGELOG.md:
- Around line 32-35: Narrow the lane-ownership compatibility claim in the
changelog and the “Lane ownership and v053” upgrade-guide section to the helper
path actually tested; only retain claims about older-binary ownership after v053
if a rehearsal verifies that version topology. Keep the documented behavior
within the evidence provided by the split-role test and released-artifact
rehearsal.
Review comments at @docs/upgrade-0.6-to-0.7.md:
- Around line 42-45: Reorder the upgrade steps so `awa migrate` runs before `awa
storage lane-sequences`, since the check requires helpers introduced by
migration. Describe the lane check as checking for remaining problems after
migration, noting that migration also attempts repairs.

panics, not only on the normal teardown path. Reuse an established test cleanup
mechanism that can safely remove partially created resources, including when the
test unwinds.

Rehearse the older-binary lane ownership claim.
The split-role test uses current QueueStorage with provisioner access revoked. The released-artifact rehearsal checks job completion, not post-v053 lane ownership. Rehearse and link the stated versions, or limit this claim and the upgrade guide to the tested helper path.
As per coding guidelines, “Link compatibility claims to rehearsals of the claimed version topology; describe narrower evidence only by the behavior it covers.”

Review comment at @CHANGELOG.md around lines 32 - 35:
Narrow the lane-ownership compatibility claim in the changelog and the “Lane
ownership and v053” upgrade-guide section to the helper path actually tested;
only retain claims about older-binary ownership after v053 if a rehearsal
verifies that version topology. Keep the documented behavior within the evidence
provided by the split-role test and released-artifact rehearsal.

Run the lane check after v053.
On a v052 database without the new helpers, awa storage lane-sequences fails with an undefined-function error. Move the check after awa migrate and describe it as a check for remaining problems; migration also attempts repairs.

Review comment at @docs/upgrade-0.6-to-0.7.md around lines 42 - 45:
Reorder the upgrade steps so `awa migrate` runs before `awa storage
lane-sequences`, since the check requires helpers introduced by migration.
Describe the lane check as checking for remaining problems after migration,
noting that migration also attempts repairs.

A queue lane’s enqueue and claim sequences belonged to whichever role first touched it. Other runtime roles could then fail with
permission denied for sequence, and a runtime without schemaCREATEcould not create a missing lane.Migration v053 installs schema-owner
SECURITY DEFINERprovisioners in every trusted queue-storage schema. New sequences mirror privileges from their head tables, so runtime roles can share lanes without relying on the creator’s default privileges. Provisioning retains the existing lane advisory lock, helper signatures and cursor semantics. New binaries fall back to the existing path before the helpers are installed; old callers use the refreshed helpers after migration.Existing sequences are repaired after the migration commits, one sequence per transaction with a 300 ms lock wait. Busy or unauthorized sequences remain reported rather than failing the completed migration.
awa storage lane-sequences [--schema S] [--repair]checks or repairs them and exits 2 while problems remain. External SQL migration runners install v053 before running that diagnostic and repair step.The repair also supports a migrator whose schema-owner membership permits
SET ROLEwithout inheritance. It transfers ownership, temporarily assumes the new owner only when grants require it, and restores the exact previous role. It does not require inherited privileges from the new owner. Repair remains invoker-authorized, with public execution revoked and transaction rollback on a lock timeout. Database-role, upgrade and CLI guidance describe these requirements.Validation at
