Fixes: IBM#1938

This commit addresses an issue where admin metrics were empty during
benchmark tests shorter than one hour because they relied on hourly
rollup jobs. The metrics query service is updated to use a three-source
aggregation:

1. Historical rollups (for data older than the retention period)
2. Raw metrics for completed hours within the retention period
3. Raw metrics from the current, incomplete hour

This ensures that metrics are always up-to-date, even before the hourly
rollup job runs, providing immediate visibility and preventing expensive
raw table scans during short-lived tests.

Test improvements:
- Fix flaky test at hour boundary (race condition)
- Remove unused patch import
- Add tests for three-source merge behavior

* fix: prevent ReDoS in SSTI validation patterns

Replace regex-based SSTI detection with a linear-time manual parser
to eliminate ReDoS vulnerability while improving bypass resistance.

Changes:
- Add _iter_template_expressions() parser that correctly handles:
  - Quoted strings (single and double quotes)
  - Escaped characters within strings
  - Nested delimiters inside quotes (e.g., "}}" in strings)
  - Continues scanning after unterminated expressions (fail-closed)
- Replace _SSTI_PATTERNS regex list with:
  - _SSTI_DANGEROUS_SUBSTRINGS tuple for keyword detection
  - _SSTI_DANGEROUS_OPERATORS tuple for arithmetic in {{ }} and {% %}
  - _SSTI_SIMPLE_TEMPLATE_PREFIXES for ${, #{, %{ expressions
- Add _has_simple_template_expression() with O(n) linear scan using rfind
- Fix type annotation for validate_parameter_length()
- Block dynamic attribute access bypasses:
  - |attr filter for dynamic attribute access (with whitespace normalization)
  - |selectattr, |sort, |map filters (can take attribute names)
  - getattr function
  - ~ operator for string concatenation (dunder name construction)
  - [ bracket notation for dynamic access
  - % operator for string formatting (e.g., '%c' % 95)
  - attribute= parameter (blocks map/selectattr/sort attribute access)
  - All escape sequences: \x, \u, \N{, \0-\7 (octal)
- Apply operator checks to both {{ }} and {% %} blocks
- Normalize whitespace around | and = before checking

Performance:
- O(n) linear scanning eliminates catastrophic backtracking
- _has_simple_template_expression uses rfind for O(n) instead of O(n²)

Security:
- Proper quote handling blocks bypasses like {{ "}}" ~ self.__class__ }}
- Escaped quote handling blocks {{ "a\"}}b" ~ self }} bypasses
- Blocks dynamic construction bypasses via string concatenation
- Blocks all escape sequence bypasses (hex, unicode, octal)
- Blocks whitespace-based bypasses around | and =
- Blocks % formatting bypasses (e.g., '%c%c' % (95,95))
- Fail-closed: continues scanning after unterminated expressions

Tests:
- Add comprehensive SSTI bypass test cases
- Add pytest.mark.timeout(30) for deterministic ReDoS detection
- Add pathological input tests for ReDoS prevention verification

Closes IBM#2366

…IBM#2569)

Implement strict per-tool timeout enforcement for all transports
(REST, SSE, StreamableHTTP, A2A) and enhance the CircuitBreakerPlugin
with half-open states, retry headers, and granular configuration.

Changes:
- Wrap all tool invocations in asyncio.wait_for with effective_timeout
- Add per-tool timeout_ms support (ms to seconds conversion)
- Add half-open state for circuit breaker recovery testing
- Add half_open_in_flight flag to prevent concurrent probe requests
- Add retry_after_seconds in violation response for rate limiting
- Add tool_timeout_total and circuit_breaker_open_total Prometheus metrics
- Add cb_timeout_failure context flag for timeout detection in plugins
- Add tool_overrides for per-tool circuit breaker configuration
- Handle both asyncio.TimeoutError and httpx.TimeoutException
- Log actual elapsed time instead of configured timeout

Fixes applied during review:
- Fix _is_error() to detect camelCase isError from model_dump(by_alias=True)
- Fix half-open probe guard: only check when st.half_open is True
- Add stale-probe timeout to prevent permanent wedge if plugin blocks
- Add timeout enforcement to A2A tool invocations
- Call tool_post_invoke on exceptions so circuit breaker tracks failures
- Add ToolTimeoutError subclass to distinguish timeouts from other errors
- Only skip post_invoke for ToolTimeoutError (not all ToolInvocationError)
- Set error_message and span attributes for ToolTimeoutError observability
- Update README to document isError camelCase support

Timeout precedence:
1. Per-tool timeout_ms (if set and non-zero)
2. Global TOOL_TIMEOUT setting (default: 60s)

…BM#2549)

Replace long-lived database sessions in RBAC middleware with
fresh_db_session() context manager to prevent session accumulation
under high concurrent load.

Changes:
- Remove db parameter from get_current_user_with_permissions()
- Use fresh_db_session() context manager for short-lived DB access
- Keep "db": None in user context for backward compatibility
- Add deprecation warnings to get_db() and get_permission_service()
- Update all permission decorators to use fresh_db_session() fallback
- Update PermissionChecker to use fresh_db_session() pattern
- Simplify db.py by reusing get_db() generator for fresh_db_session

Security fixes:
- Use named kwargs (user, _user, current_user, current_user_ctx) for
  user context extraction instead of scanning all dicts for "email"
  to prevent request body injection attacks

Performance fixes:
- PermissionChecker.has_any_permission now uses single session for
  all permission checks instead of opening N sessions

This prevents idle-in-transaction bottlenecks where sessions were
held for entire request duration instead of milliseconds.

* feat: unified PDP plugin for issue IBM#2223

decisions across multiple policy engines (Native RBAC, MAC, OPA, Cedar).

- plugins/unified_pdp/unified_pdp.py  — Plugin class, hooks into
  tool_pre_invoke and resource_pre_fetch
- plugins/unified_pdp/pdp.py          — PolicyDecisionPoint orchestrator
- plugins/unified_pdp/pdp_models.py   — Pydantic models (Subject, Resource,
  Context, AccessDecision, config types)
- plugins/unified_pdp/adapter.py      — Abstract engine adapter base class
- plugins/unified_pdp/cache.py        — TTL-aware decision cache
- plugins/unified_pdp/engines/        — Four engine adapters: native_engine,
  mac_engine, opa_engine, cedar_engine
- plugins/unified_pdp/default_rules.json — Starter RBAC ruleset
- tests/unit/plugins/test_unified_pdp.py — 46 unit tests
- plugins/config.yaml                 — Plugin registration (mode: disabled)
- MANIFEST.in                         — Added recursive-include plugins *.json

Combination modes: all_must_allow | any_allow | first_match

- Explicit null teams without admin → empty list (public-only)
- Empty teams array → empty list (public-only)
- Team list → normalized string IDs (team-scoped)

Additional changes:

* fix(rbac): add explicit db dependency to RBAC-protected routes

Address load test findings from RCA #1 and #2:

- Add `db: Session = Depends(get_db)` to routes in email_auth.py,

- Fix test files to pass mock_db parameter after signature changes
- Add shm_size: 256m to PostgreSQL in docker-compose.yml
- Remove non-serializable content from resource update events
- Disable CircuitBreaker plugin for consistent load testing

* fix(db): resolve transaction leak and connection pool exhaustion

Critical fixes for load test failures at 4000 concurrent users:

- Add explicit asyncio.CancelledError handling in get_db() context manager
- When MCP handlers are cancelled (client disconnect, timeout), the finally
  block may not execute properly, leaving transactions "idle in transaction"
- Now explicitly rollback and close before re-raising CancelledError
- Add rollback in direct SessionLocal usage at line ~1425

Issue #2 - Missing db parameter in admin routes (HIGH):
- Add `db: Session = Depends(get_db)` to 73 remaining admin routes
- Routes with @require_permission but no db param caused decorator to
  create fresh session via fresh_db_session() for EVERY permission check
- This doubled connection usage for affected routes under load

Issue #3 - Slow recovery from transaction leaks (MEDIUM):
- Reduce IDLE_TRANSACTION_TIMEOUT from 300s to 30s in docker-compose.yml
- Reduce CLIENT_IDLE_TIMEOUT from 300s to 60s
- Leaked transactions now killed faster, preventing pool exhaustion

Root cause confirmed: list_resources() MCP handler was primary source,
with 155+ connections stuck on `SELECT resources.*` for up to 273 seconds.

See todo/rca2.md for full analysis including live test data showing
connection leak progression and 606+ idle transaction timeout errors.

* fix(teams): use consistent user context format across all endpoints

- Update request_to_join_team and leave_team to use dict-based user context
- Fix teams router to use get_current_user_with_permissions consistently
- Move /discover route before /{team_id} to prevent route shadowing
- Update test fixtures to use mock_user_context dict format
- Add transaction commits in resource_service to prevent connection leaks
- Add missing docstring parameters for flake8 compliance

* fix(db): add explicit db.commit/close to prevent transaction leaks

Add explicit db.commit(); db.close() calls to 100+ endpoints across
all routers to prevent PostgreSQL connection leaks under high load.

Problem: Under high concurrency, FastAPI's Depends(get_db) cleanup
runs after response serialization, causing transactions to remain
in 'idle in transaction' state for 20-30+ seconds, exhausting the
connection pool.

Solution: Explicitly commit and close database sessions immediately
after database operations complete, before response serialization.

Routers fixed:
- tokens.py: 10 endpoints (create, list, get, update, revoke, usage, admin, team tokens)
- llm_config_router.py: 14 endpoints (provider/model CRUD, health, gateway models)
- sso.py: 5 endpoints (SSO provider CRUD)
- email_auth.py: 3 endpoints (user create/update/delete)
- oauth_router.py: 1 endpoint (delete_registered_client)
- teams.py: 18 endpoints (team CRUD, members, invitations, join requests)
- rbac.py: 12 endpoints (roles, user roles, permissions)
- main.py: 14 CUD + 3 list + 7 RPC handlers

Also fixes:
- admin.py: Rename 21 unused db params to _db (pylint W0613)
- test_teams*.py: Add mock_db fixture to tests calling router functions directly
- Add llms/audit-db-transaction-management.md for future audits

* fix(rpc): fix list_gateways tuple unpacking and add token scoping

The RPC list_gateways handler had two bugs:
1. Did not unpack the tuple (gateways, next_cursor) returned by
   gateway_service.list_gateways(), causing 'list' object has no
   attribute 'model_dump' error
2. Was missing token scoping via _get_rpc_filter_context(), which
   was the original R-02 security fix

Also fixed all callers of list_gateways that expected a list but
now receive a tuple:
- mcpgateway/admin.py: get_gateways_section()
- mcpgateway/services/import_service.py: 3 call sites

Updated test mocks to return (list, None) tuples instead of lists.

* fix(teams): build response before db.close() to avoid lazy-load errors

The teams router was calling db.commit(); db.close() before building
the TeamResponse, but TeamResponse includes team.get_member_count()
which needs an active session. When the session is closed, the fallback
in get_member_count() tries to access self.members (lazy-loaded),
causing "Parent instance is not bound to a Session" errors.

Fixed by building TeamResponse BEFORE calling db.close() in:
- create_team
- get_team
- update_team

* fix(teams): fix update_team expecting team object but getting bool

The service's update_team() returns bool, but the router was treating
the return value as a team object and trying to access .id, .name, etc.

Fixed by:
1. Checking the boolean return value for success
2. Fetching the team again after successful update to build the response

* fix(teams): fix update_member_role return type mismatch

The service's update_member_role() returns bool, but the router

* fix: eliminate redundant DB queries in read_resource and invoke_resource

Steps 3-4 of load test RCA: reduce per-request query count from 6 to 2
for resource-by-ID requests.

Step 3: After Q2 (db.get), check enabled in Python and guard Q3/Q4 with
resource_db is None so they only run for URI-only lookups.

Step 4: Add joinedload(DbResource.gateway) to Q2, pass pre-fetched
resource_obj and gateway_obj to invoke_resource() to skip Q5/Q6.

Closes IBM#2563

This commit fixes two issues:

1. Gateway Tags Returned as Empty List (IBM#2563):
   - Fixed type annotation mismatch in validate_tags_field() to correctly
     return List[Dict[str, str]] instead of List[str]
   - Added passthrough logic for already-formatted tag dictionaries in
     TagValidator.validate_list()
   - Updated GatewayCreate.tags and GatewayUpdate.tags to accept both
     legacy string format and new dict format
   - Fixed parenthesis placement in get_gateway_by_url() to correctly
     call masked() on GatewayRead instead of DbGateway

2. Transport Field Reset During Gateway Update:
   - Changed GatewayUpdate.transport from default="SSE" to None to
     prevent overwriting existing values when field is omitted in
     PUT/PATCH requests
