fix(db): drop stale auth unique on sqlite push subscriptions#3391fallenbagel wants to merge 1 commit into
Conversation
The sqlite twin of UpdateWebPush never dropped the UNIQUE on user_push_subscription.auth that the postgres twin dropped, so the sqlite carried a constraint that was neither in the entity nor the postgres. This meant that TypeORM cannot correct this on its own as the rebuild generated since has carried an unrelated user_push_subscription rebuild as a result. This issue came from a merge issue when seerr was jellyseerr and was merging from usptream.

Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🟡 Moderate · up to This migration removes the stale SQLite uniqueness constraint, but rollback can fail if duplicate auth values are present because it attempts to restore that constraint. Add a duplicate check and explicit rollback policy, or obtain owner acceptance of the bounded rollback risk before merging. Suggested reviewers: Poem

- Around line 31-34: Update the down migration before its table-recreation DDL
to detect duplicate auth values and apply a deterministic, non-destructive
resolution policy that preserves all subscriptions; ensure the subsequent INSERT
into the unique-auth table cannot fail. Use the migration’s existing queryRunner
flow and preserve the intended rollback behavior.

Pull request overview
Adds a hand-written SQLite migration to remove the stale UNIQUE constraint on user_push_subscription.auth so SQLite schema aligns with the entity definition and Postgres, preventing TypeORM from repeatedly generating non-converging “rebuild table” noise in future SQLite migrations.
Changes:
- Add a new SQLite migration that rebuilds
user_push_subscriptionwithout theUQ_f90ab5a4ed54905a4bb51a7148bUNIQUE onauth. - Preserve the remaining constraints/indexes (
endpoint + userIdunique,userIdFK,userIdindex) and provide a rollback path.

- Same robustness issue in
down():DROP INDEXwill fail if the index is already missing. UsingDROP INDEX IF EXISTSmakes rollbacks safer.
await queryRunner.query(`DROP INDEX "IDX_03f7958328e311761b0de675fb"`);

- And for rollback index recreation,
CREATE INDEX IF NOT EXISTSavoids failing the rollback if the index already exists (e.g., if the rollback is rerun after a partial failure).

Description
user_push_subscription.authcarries a UNIQUE constraint on sqlite that neither the entity nor postgres has. The constraintUQ_f90ab5a4ed54905a4bb51a7148b.The
UpdateWebPushpair diverged.postgres/1743023615532-UpdateWebPush.tsdrops the constraint, and the sqlite twin1743023610704-UpdateWebPush.tsnever does, carrying it forward through four rebuilds instead. This dates to an upstream overseerr merge issue, which is also why there are twoUpdateWebPushmigrations.TypeORM cannot generate a fix. It sees the extra unique and emits a table rebuild to drop it, but the temp table it produces re-includes
UQ_f90ab5a4ed54905a4bb51a7148b, so the diff never converges and it emits the rebuild twice perup(). The practical cost of that was that every generated sqlite migration inherited the noise. For example,1781732036510-AddIgnoreQuotaToMediaRequestcarries 12user_push_subscriptionreferences that have nothing to do with its subject.How Has This Been Tested?
I have tested this extensively with sqlite and postgres on fresh and already existing instances. No behavioural changes. It just fixes sqlite's broken migration generation
