Task 4 (Better Jail Configuration) implementation:
- Add fail2ban_config_dir setting to app/config.py
- New file_config_service: list/view/edit/create jail.d, filter.d, action.d files
with path-traversal prevention and 512 KB content size limit
- New file_config router: GET/PUT/POST endpoints for jail files, filter files,
and action files; PUT .../enabled for toggle on/off
- Extend config_service with delete_log_path() and add_log_path()
- Add DELETE /api/config/jails/{name}/logpath and POST /api/config/jails/{name}/logpath
- Extend geo router with re-resolve endpoint; add geo_re_resolve background task
- Update blocklist_service with revised scheduling helpers
- Update Docker compose files with BANGUI_FAIL2BAN_CONFIG_DIR env var and
rw volume mount for the fail2ban config directory
- Frontend: new Jail Files, Filters, Actions tabs in ConfigPage; file editor
with accordion-per-file, editable textarea, save/create; add/delete log paths
- Frontend: types in types/config.ts; API calls in api/config.ts and api/endpoints.ts
- 63 new backend tests (test_file_config_service, test_file_config, test_geo_re_resolve)
- 6 new frontend tests in ConfigPageLogPath.test.tsx
- ruff, mypy --strict, tsc --noEmit, eslint: all clean; 617 backend tests pass
- Cache setup_completed flag in app.state._setup_complete_cached after
first successful is_setup_complete() call; all subsequent API requests
skip the DB query entirely (one-way transition, cleared on restart).
- Add in-memory session token TTL cache (10 s) in require_auth; the second
request with the same token within the window skips session_repo.get_session.
- Call invalidate_session_cache() on logout so revoked tokens are evicted
immediately rather than waiting for TTL expiry.
- Add clear_session_cache() for test isolation.
- 5 new tests covering the cached fast-path for both optimisations.
- 460 tests pass, 83% coverage, zero ruff/mypy warnings.
- Remove per-IP db.commit() from _persist_entry() and _persist_neg_entry();
add a single commit after the full lookup_batch() chunk loop instead.
Reduces commits from ~5,200 to 1 per bans/by-country request.
- Remove db dependency from GET /api/dashboard/bans and
GET /api/dashboard/bans/by-country; pass app_db=None so no SQLite
writes occur during read-only requests.
- Add _dirty set to geo_service; _store() marks resolved IPs dirty.
New flush_dirty(db) batch-upserts all dirty entries in one transaction.
New geo_cache_flush APScheduler task flushes every 60 s so geo data
is persisted without blocking requests.
- Add 5-min negative cache (_neg_cache) so failing IPs are throttled
rather than hammering the API on every request
- Add MaxMind GeoLite2 fallback (init_geoip / _geoip_lookup) that fires
when ip-api fails; controlled by BANGUI_GEOIP_DB_PATH env var
- Fix lookup_batch bug: failed API results were stored in positive cache
- Add _persist_neg_entry: INSERT OR IGNORE into geo_cache with NULL
country_code so re-resolve can find historically failed IPs
- Add POST /api/geo/re-resolve: clears neg cache, batch-retries all
geo_cache rows with country_code IS NULL, returns resolved/total count
- BanTable + MapPage: wrap the country — placeholder in a Fluent UI
Tooltip explaining the retry behaviour
- Add geoip2>=4.8.0 dependency; geoip_db_path config setting
- Tests: add TestNegativeCache (4), TestGeoipFallback (4), TestReResolve (4)
- Add persistent geo_cache SQLite table (db.py)
- Rewrite geo_service: batch API (100 IPs/call), two-tier cache,
no caching of failed lookups so they are retried
- Pre-warm geo cache from DB on startup (main.py lifespan)
- Rewrite bans_by_country: SQL GROUP BY ip aggregation + lookup_batch
instead of 2000-row fetch + asyncio.gather individual calls
- Pre-warm geo cache after blocklist import (blocklist_service)
- Add 300ms debounce to useMapData hook to cancel stale requests
- Add perf benchmark asserting <2s for 10k bans
- Add seed_10k_bans.py script for manual perf testing
In the Docker image, the app source is copied to /app/app/ (not
backend/app/), so parents[2] resolved to '/' instead of /app.
This left the fail2ban package absent from sys.path, causing every
pickle.loads() call on socket responses to raise:
ModuleNotFoundError: No module named 'fail2ban'
Replace the hardcoded parents[2] with a walk-up search that iterates
over all ancestors until it finds a fail2ban-master/ sibling directory.
Works correctly in both local dev and Docker without environment-specific
path magic.
