stem_redis 0.3.1

Redis broker, result backend, and scheduler utilities for Stem.

Changelog

0.3.1

• Replace an earlier dead-letter record when the same logical task ID is dead-lettered again.

0.3.0

• Require Dart >=3.13.0 <4.0.0.
• Preserve error data and timestamps for every terminal run. Use explicit topic prefixes for cleanup, including terminal failures and caller-supplied IDs containing :wf:. Reject malformed journal writes and empty journal fences.
• Add separate Lua-backed workflow journals with atomic execution/revision CAS, checkpoint ordering, compensation ordering, and atomic journal-aware rewind.
• Add Lua-atomic first-terminal-wins completion/cancellation and prevent ordinary workflow mutations from resurrecting terminal runs.
• Add Redis workflow execution fencing with a fresh executionId per claim, conditional lease renewal/release, and managed terminal-failure recording. Non-terminal error recording preserves the run status and lease for retry; terminal failure clears the lease only for the current execution.
• Require Stem >=0.5.0 <1.0.0 and the shared adapter contract >=0.3.0 <1.0.0, allowing later pre-1.0 releases.

0.2.1

• Widened Stem compatibility to include the 0.4 portable runtime line.
• Updated the Redis adapter for the Stem 0.3.0 release train and Dart 3.12 minimum.
• Added an atomic Redis Lua terminal-result write that preserves the first terminal task state across concurrent workers.
• Updated the Redis adapter for Stem 0.3.0 and the capability-aware broker contract.
• Retained the production distributed Redis rate limiter and added its focused unit and integration coverage.
• Redis lock acquisition now allocates an atomic, monotonic fencing token while retaining owner-checked renewal and release behavior.

0.1.3

• Added the production RedisRateLimiter, an atomic Redis Lua token bucket with Redis-server time, retry-after decisions, TLS support, and namespaced keys.
• Removed the prerelease core dependency range from the published-package manifest.

0.1.2

• Added the production RedisRateLimiter, an atomic Redis Lua token bucket with Redis-server time, retry-after decisions, TLS support, and namespaced keys.

0.1.1

• Updated the Redis workflow store to honor caller-provided run ids, matching the runtime metadata/manifests contract used by the core workflow views.
• Rejected duplicate caller-provided workflow run ids atomically so existing run and checkpoint state is preserved on collisions.
• Enabled broadcast fan-out broker contract coverage in Redis integration tests by wiring additional broker instances for shared-namespace fan-out checks.

0.1.0

• Added workflow run lease tracking and claim/renew helpers to distribute workflow execution safely across workers.
• Maintenance updates to adapter tooling and formatting (no runtime changes).
• Added Redis workflow store support with runnable discovery and metadata paging improvements.
• Migrated IDs to UUID v7 and updated datasource handling.
• Added workflow store contract tests and refreshed dependencies/docs.

0.1.0-alpha.4

• Added durable watcher storage and atomic event delivery so Durable Workflows resume with persisted payloads and metadata.
• Treat saveStep as a heartbeat, auto-version checkpoints in sorted sets, and propagate suspension resumeAt/deadline data across Redis structures.
• Improved queue maintenance by purging priority streams and shutting down claim timers when consumers stop, preventing spurious reclaims.
• Published redisWorkflowStoreFactory so CLI tooling and integration tests can spin up Redis-backed Durable Workflow stores with one helper.
• Added lock-store contract coverage for RedisLockStore, validating the semantics required by TaskOptions.unique and scheduler coordination.

0.1.0-alpha.3

• Initial release containing Redis Streams broker, result backend, scheduler helpers, and contract tests extracted from the core stem package.
