Each invocation generates a unique caller identity (UUID) to prevent re-entrant lock - acquisition by concurrent sessions on the same plan. Concurrent attempts now raise `LockConflictError` - instead of silently racing. Lock is acquired before phase transition and released in a `finally` - block to ensure cleanup even on error. - -- **`--format color` ANSI Output** (#7910): Fixed `format_output` routing the `color` format - option to `_format_plain`, which produced plain uncoloured text instead of ANSI escape - sequences. The `color` format is now routed to `format_output_session` which uses the - `ColorMaterializer` to emit proper ANSI-coloured output. `--format plain` and all other - formats remain unaffected. - -- **ContextTierService Thread Safety** (#7547): Added `threading.RLock` to - `ContextTierService` to prevent `RuntimeError: dictionary changed size during - iteration` and data corruption under concurrent plan execution. All public - methods (`store`, `get`, `promote`, `demote`, `evict_lru`, `enforce_staleness`, - `get_metrics`, `get_all_fragments`, `get_hot_fragments`, `get_for_actor`, - `get_scoped_view`, `get_scoped_by_resource`, `get_scoped_metrics`) now acquire - the reentrant lock before accessing the hot/warm/cold tier dicts. The service - was previously documented as single-threaded but registered as a DI Singleton, - causing potential data corruption when parallel subplans shared the same - instance. The `TierRuntimeMixin.enforce_staleness()` and - `ScopedTierMixin.get_scoped_by_resource()` / `get_scoped_metrics()` methods - are also protected. The DI container registration as `providers.Singleton` - is now correct and safe. +- **Data Integrity Fix** (#7489): Removed `session.rollback()` calls from `ProjectRepository.create()` error handlers. Repositories that receive an externally-owned session from `UnitOfWork` must not call `rollback()` on that session, as doing so rolls back all pending work in the shared transaction. The `UnitOfWork` is now the sole owner responsible for transaction lifecycle management (commit/rollback). - **TOCTOU Race Condition in Git Worktree Sandbox** (#7507): Fixed Time-Of-Check-To-Time-Of-Use race condition in `GitWorktreeSandbox.create()` by replacing unsafe mkdtemp+rmdir pattern with persistent parent directory approach. Parent directory is now held throughout operation lifetime and properly cleaned up in all error paths (timeout, CalledProcessError, OSError) and in the cleanup() method, eliminating race window where another process could claim the worktree path. Comprehensive BDD coverage added for all error-path cleanup branches. diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index 65b9ab558..8af4b752f 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -14,12 +14,7 @@ Below are some of the specific details of various contributions. * Jeffrey Phillips Freeman has acted as Lead Developer, daily contributor, and Project Owner. * Brent E.
