- Add stop_grace_period to backend container for graceful shutdown
- Document WAL mode rationale and orphaned file cleanup in db.py
- Handle database close errors gracefully in lifespan
- Clean up orphaned WAL files during startup before opening DB
- Reorder imports and fix formatting in startup.py
New exceptions: DatabaseBusyError, DatabasePermissionDeniedError,
DatabasePathInvalidError, DatabaseCorruptedError, DatabaseUnavailableError.
open_db creates parent directory if missing. Catches all aiosqlite errors
and maps to specific exception types.
get_db retries up to 3x on locked database with backoff.
Propagates specific exceptions instead of generic HTTPException.
Tests for all new error types and retry behavior.
- Document database error handling, logging duplication, ban service
timestamp, and orphaned SQLite file issues in Tasks.md
- Bump backend version from 0.9.19-rc.4 to 0.9.19-rc.5
Migration 1: remove idx_sessions_token_hash from _SCHEMA_STATEMENTS.
The legacy schema has sessions.token (not token_hash). The IF NOT EXISTS
guard only prevents duplicate index names — it still requires the column
to exist. Migration 2 drops and rebuilds sessions with token_hash anyway,
so creating the index in migration 1 was redundant.
Migration 3: replace ALTER TABLE ADD COLUMN with a table rebuild.
SQLite rejects ALTER TABLE ADD COLUMN NOT NULL DEFAULT <expression> when
the table already contains rows. The old DB has ~181k geo_cache rows, so
the ALTER always failed. Rebuild copies existing rows with last_seen set
to cached_at as a reasonable approximation of last-seen time.
A 502 Bad Gateway is a server/gateway error, not a network error.
Logging it as a 'Session validation network error' is noisy and
misleading during startup when nginx is temporarily unreachable.
Silently skip the console.warn for 5xx errors in handleValidationError
while keeping the warning for actual network errors.
- Add release candidate (rc) support to release.sh with latestRC tagging
- Bump VERSION, backend pyproject.toml, and frontend package.json to 0.9.19-rc.1
- Add local frontend/openapi.json so build no longer needs running backend
- Update generate:types and validate-types.sh to use local openapi.json
- Fix frontend tests: remove unused imports/variables and update mock data
