- Introduced caching mechanism with expiration for message feeds to improve performance.
- Added logging for cache expiration events to aid in debugging.
- Updated MessagesPanel to reopen search bar when participant filters are active.
- Added test cases for handling tmux server errors and message panel behavior with filters.
- Updated `getClaudeLogs` method to support asynchronous fetching of logs.
- Introduced new interfaces for retained logs and transcript cache entries.
- Added logic to retain and retrieve Claude logs even after cleanup of live runs.
- Implemented fallback mechanism to use persisted transcripts when no live run exists.
- Updated tests to cover new log retention and retrieval scenarios.
Remove the SessionDetail.messages stripping and related cache-size
change per maintainer feedback. The session-detail optimization will
follow separately after PR #58 lands with the right architectural
pattern (lightweight snapshot + separate endpoints).
This PR now contains only:
- progressPayload helpers (buildProgressLogsTail, buildProgressAssistantOutput)
- cap applied to emitLogsProgress, updateProgress, stall warning, retry error
- throttle raised 300ms -> 1000ms
- tests for the progress payload behavior
Users with long-running teams (37+ tasks, 10+ agents for an hour) were
hitting constant renderer crashes (issue #36). Two hot paths were
serializing unbounded histories across IPC on every tick:
- Provisioning progress: emitLogsProgress and updateProgress both
joined the full provisioningOutputParts array (~20 event-driven call
sites) plus the full CLI log tail, then fanned that out to the
renderer. After an hour, each tick shipped multi-megabyte payloads
and Zustand OOM'd on the immutable state clone.
- Session detail cache: SessionDetail.messages (the raw parsed JSONL)
was being cached and returned over IPC/HTTP even though the renderer
only reads session/chunks/processes/metrics. This roughly doubled
the per-entry cache footprint on large sessions.
Fixes:
- Add progressPayload helpers that cap the log tail to 200 lines and
assistant output to the last 20 parts; empty/whitespace joins
collapse to undefined so the noop guard is explicit rather than
coincidental.
- Apply the cap inside emitLogsProgress, updateProgress, and the two
inline emission paths (stall warning, retry error). Throttle the
log-progress tick 300ms -> 1000ms so Zustand can keep up.
- Add stripSessionDetailMessages and call it at every SessionDetail
production site that crosses IPC/HTTP (both sessions.ts routes,
both cache stores).
- Raise MAX_CACHE_SESSIONS 5 -> 20 now that the per-entry SessionDetail
footprint is bounded. Previously 5 forced constant re-parsing on
every session switch.
Tests: 15 new unit tests covering the helpers (tail slicing, empty
parts, whitespace-only parts, non-mutation of inputs).
