Previously the AbortController was created inside useEffect, which runs
after render. This meant requests initiated during render received
the previous cycle's (possibly aborted) signal and were cancelled
immediately instead of completing.
Now the controller is created synchronously when pathname changes, before
any request can be initiated on the new route. The old controller is
aborted in the same conditional block, before the new one is created.
Side effect: removed resolved Issue #49 from Tasks.md.

Stale sessions from a stolen device could be reused up to the cache
TTL after a legitimate user re-logs in, because login never cleared
the existing cache entry.
Changes:
- Add invalidate_by_user(user_id) to SessionCache protocol
- InMemorySessionCache maintains a user_id -> set[token] index to
support O(1) invalidation of all sessions for a given user
- NoOpSessionCache stub updated for API compatibility
- auth_service.login() now returns the Session object alongside
signed_token and expires_at
- login router calls session_cache.invalidate_by_user(session.id)
immediately after successful authentication

Fail with RuntimeError when WEB_CONCURRENCY or BANGUI_WORKERS > 1.
In-memory session cache, rate-limit windows, and runtime state are
process-local. Multi-worker silently causes stale limits, ghost sessions,
inconsistent status.

Add explicit HTTP status code documentation to every endpoint
across 15 router files. Each endpoint now declares all possible
response codes (200/201/204/400/401/404/409/429/502/503) with
descriptions so frontend can distinguish error types.

- Add optional requestKey parameter to UseFetchDataOptions
- Implement module-level cache (inFlightRequests) to track in-flight requests
- When requestKey is provided, multiple hook instances with same key share in-flight requests
- Prevents duplicate API calls when multiple components fetch same data or rapid refresh calls
- Cache entries are automatically cleared when response arrives (success or error)
- Maintains backward compatibility: without requestKey, behaves as before
- Adds comprehensive tests for deduplication scenarios
This reduces bandwidth waste and prevents race conditions caused by concurrent requests for identical data.

This commit adds support for shipping logs to external centralized logging platforms, addressing the MEDIUM priority task for structured logging infrastructure.
## Key Changes:
### 1. New Documentation: Docs/Observability.md
- Comprehensive guide to logging architecture and configuration
- Covers all three supported platforms (Datadog, Papertrail, Elasticsearch)
- Includes best practices, security considerations, and troubleshooting
- Documents sensitive data handling and compliance requirements
### 2. Core Implementation: app/utils/external_logging.py
- ExternalLogHandler: Abstract base class for non-blocking log delivery
- DatadogLogHandler: HTTP API integration with JSON payloads
- PapertrailLogHandler: Syslog protocol over TCP
- ElasticsearchLogHandler: Bulk API integration with NDJSON format
- Features:
- Async buffering with configurable batch size and flush interval
- Exponential backoff retry logic
- Non-blocking delivery (never blocks application logic)
- Proper error handling and internal logging
- Lifecycle management (start/shutdown)
### 3. Configuration: app/config.py
- New Settings fields for external logging:
- external_logging_enabled (default: False)
- external_logging_provider (datadog/papertrail/elasticsearch)
- external_logging_buffer_size (default: 1000)
- external_logging_flush_interval_seconds (default: 5.0)
- Provider-specific configuration (API keys, hosts, batch sizes)
- All fields have sensible defaults
- Full field validation and normalization
### 4. Integration: app/main.py
- Global _external_log_handler for application lifecycle
- _external_logging_processor: structlog processor for handler integration
- Updated _configure_logging(): Add handler to processor chain when enabled
- Updated _lifespan(): Initialize handler before startup, shutdown on termination
### 5. Tests: backend/tests/test_external_logging.py
- 20 comprehensive tests covering all handlers and factory
- Configuration validation tests
- All tests passing
## Design Decisions:
1. **Non-blocking Delivery**: External logging never blocks request handling.
Failures are logged locally but don't impact application.
2. **Buffering Strategy**: In-memory buffer with configurable size prevents
unbounded memory growth. When buffer fills, oldest logs are dropped with
a warning.
3. **Retry Logic**: Transient failures (timeouts, 5xx errors) are retried
with exponential backoff. Permanent failures (bad credentials) are logged
and skipped.
4. **Disabled by Default**: External logging is opt-in via environment
variables, maintaining backward compatibility with existing deployments.
5. **Provider Flexibility**: Support for multiple platforms allows users to
choose based on their infrastructure (cloud-native, on-premise, etc).
## Backward Compatibility:
- All new configuration fields have defaults
- External logging disabled by default
- No changes to existing logging behavior unless explicitly configured
- No new required dependencies
## Testing:
- All 20 new tests passing
- Existing tests unaffected (same count of passing tests)
- Configuration validation tested
- Handler creation and lifecycle management tested

Adds support for gradual session secret rotation without forcing logout:
- Add BANGUI_SESSION_SECRET_PREVIOUS config field for rotation window
- Implement unwrap_session_token_with_rotation() to accept tokens signed with
either current or previous secret
- Update validate_session() to transparently accept old tokens during rotation
- Update logout() to accept tokens from both secrets
- Add comprehensive logging for rotation events and metrics
- Add 8 new tests covering all rotation scenarios
- Update documentation with step-by-step rotation strategy
- Update .env.example with previous secret field
Key features:
- No forced logout: old tokens continue working during rotation window
- Transparent validation: old tokens are automatically logged for monitoring
- Production-safe: can rotate secrets without service interruption
- Metrics-ready: logs track token rotation for observability
Rotation workflow:
1. Generate new secret and set BANGUI_SESSION_SECRET
2. Set BANGUI_SESSION_SECRET_PREVIOUS to old secret
3. Wait for old tokens to expire (≥ session_duration_minutes)
4. Unset BANGUI_SESSION_SECRET_PREVIOUS to complete rotation

Add AbortController refs and abort signal checks to prevent race conditions
and memory leaks when components unmount or new requests are initiated.
Components fixed:
- JailsTab.tsx: validation handler with AbortController pattern
- JailInfoSection.tsx: handle function with useCallback wrapper
- RawConfigSection.tsx: fetch handler with abort checks
- ConfFilesTab.tsx: file fetch handler with abort signal verification
- IgnoreListSection.tsx: three handlers (add, remove, toggle) with callbacks
All handlers now:
1. Abort previous requests before initiating new ones
2. Create and store new AbortController instances
3. Check abort status before state updates in .then()/.catch()
4. Include cleanup effects that abort on unmount

The API pagination infrastructure was already correctly implemented with:
- PaginatedListResponse base model containing 'items' and 'pagination' fields
- PaginationMetadata object with all required fields (page, page_size, total, total_pages, has_next_page, has_prev_page)
- All services correctly calling create_pagination_metadata()
However, there were two bugs preventing tests from passing:
1. IMPORT BUG: time_utils.py was importing TIME_RANGE_SECONDS from app.models.ban
when it's actually defined in app.models._common. This caused import errors
in tests that exercise time-range filtering.
2. TEST BUG: Test assertions were using outdated API structure, accessing
.total, .page, .page_size directly on paginated responses instead of
through the .pagination object.
Fixed locations:
- test_mappers/test_ban_mappers.py: 3 assertions updated to use .pagination.*
- test_services/test_blocklist_service.py: 6 assertions updated
- test_services/test_history_service.py: 14 assertions updated
All paginated API endpoints now correctly return pagination metadata:
- GET /api/history
- GET /api/history/archive
- GET /api/dashboard/bans
- GET /api/jails/{name}/banned
- GET /api/blocklists/log
Verified with 24 passing pagination tests demonstrating correct behavior.

- Create PaginationMetadata model with computed derived fields (total_pages, has_next_page, has_prev_page)
- Update PaginatedListResponse to embed pagination metadata in a separate 'pagination' object
- Add create_pagination_metadata() factory function in utils/pagination.py for consistent computation
- Update all paginated service functions to use new structure:
- history_service.list_history()
- blocklist_service.get_import_logs()
- jail_service.get_jail_banned_ips()
- ban_mappers.map_domain_dashboard_ban_list_to_response()
- Update response model docstrings with new structure examples
- Update Backend-Development.md documentation with new pagination patterns
- Update test fixtures to work with new response structure
Response shape changes from:
{"items": [...], "total": 100, "page": 1, "page_size": 50}
To:
{"items": [...], "pagination": {"page": 1, "page_size": 50, "total": 100, "total_pages": 2, "has_next_page": true, "has_prev_page": false}}
Benefits:
- Frontend receives all pagination state needed for UI controls
- No need for frontend to calculate total_pages or page navigation logic
- Consolidated pagination metadata reduces field sprawl
- OpenAPI schema automatically reflects changes
