Use NoOpSessionCache in backend/app/main.py and dynamically switch cache implementation in backend/app/dependencies.py so disabled cache mode remains safe while get_session_cache always returns a valid object.
Wire DEFAULT_BLOCKING_EXECUTOR as the default executor in backend/app/utils/async_utils.py, preserving custom executors and marking Task 22 completed in Docs/Tasks.md.
- Add TYPE_CHECKING guards for runtime-expensive imports (aiohttp, aiosqlite)
- Reorganize imports to follow PEP 8 conventions
- Convert TypeAlias to modern PEP 695 type syntax (where appropriate)
- Use Sequence/Mapping from collections.abc for type hints (covariant)
- Replace string literals with cast() for improved type inference
- Fix casting of Fail2BanResponse and TypedDict patterns
- Add IpLookupResult TypedDict for precise return type annotation
- Reformat overlong lines for readability (120 char limit)
- Add asyncio_mode and filterwarnings to pytest config
- Update test fixtures with improved type hints
This improves mypy type checking and makes type relationships explicit.
On startup BanGUI now verifies that the four fail2ban jail config files
required by its two custom jails (manual-Jail and blocklist-import) are
present in `$fail2ban_config_dir/jail.d`. Any missing file is created
with the correct default content; existing files are never overwritten.
Files managed:
- manual-Jail.conf (enabled=false template)
- manual-Jail.local (enabled=true override)
- blocklist-import.conf (enabled=false template)
- blocklist-import.local (enabled=true override)
The check runs in the lifespan hook immediately after logging is
configured, before the database is opened.
Stage 1.1-1.3: reload_all include/exclude_jails params already implemented;
added keyword-arg assertions in router and service tests.
Stage 2.1/6.1: _send_command_sync retry loop (3 attempts, 150ms exp backoff)
retrying on EAGAIN/ECONNREFUSED/ENOBUFS; immediate raise on all other errors.
Stage 2.2: asyncio.Lock at module level in jail_service.reload_all to
serialize concurrent reload--all commands.
Stage 3.1: activate_jail re-queries _get_active_jail_names after reload;
returns active=False with descriptive message if jail did not start.
Stage 4.1/6.2: asyncio.Semaphore (max 10) in Fail2BanClient.send, lazy-
initialized; logs fail2ban_command_waiting_semaphore at debug when waiting.
Stage 5.1/5.2: unit tests asserting reload_all is called with include_jails
and exclude_jails; activation verification happy/sad path tests.
Stage 6.3: TestSendCommandSyncRetry (5 cases) + TestFail2BanClientSemaphore
concurrency test.
Stage 7.1-7.3: _since_unix uses time.time(); bans_by_jail debug logging with
since_iso; diagnostic warning when total==0 despite table rows; unit test
verifying the warning fires for stale data.
