Fixes#17971
When initSessionState() reads the session store, use skipCache: true
to ensure fresh data from disk. The session store cache is process-local
and uses mtime-based invalidation, which can fail in these scenarios:
1. Multiple gateway processes (each has separate in-memory cache)
2. Windows file system where mtime granularity may miss rapid writes
3. Race conditions between messages 6-8 seconds apart
Symptoms: 134+ orphaned .jsonl transcript files, each with only 1
exchange. Session rotates on every incoming message even when
sessionKey is stable.
Root cause: loadSessionStore() returns stale cache → entry not found
for sessionKey → new sessionId generated → new transcript file.
The fix ensures session identity (sessionId) is always resolved from
the latest on-disk state, not potentially-stale cache.
Follow-up to #18066 — three session file write sites were missed:
- auto-reply/reply/session.ts: forked session transcript header
- pi-embedded-runner/session-manager-init.ts: session file reset
- gateway/server-methods/sessions.ts: compacted transcript rewrite
All now use mode 0o600 consistent with transcript.ts and chat.ts.
When a user interacts with the bot inside a DM topic (thread), the
session persists `lastThreadId`. If the user later sends a message
from the main DM (no topic), `ctx.MessageThreadId` is undefined and
the `||` fallback picks up the stale persisted value — causing the
bot to reply into the old topic instead of the main conversation.
Only fall back to `baseEntry.lastThreadId` for thread sessions where
the fallback is meaningful (e.g. consecutive messages in the same
thread). Non-thread sessions now correctly leave threadId unset.

* feat(slack): populate thread session with existing thread history
When a new session is created for a Slack thread, fetch and inject
the full thread history as context. This preserves conversation
continuity so the bot knows what it previously said in the thread.
- Add resolveSlackThreadHistory() to fetch all thread messages
- Add ThreadHistoryBody to context payload
- Use thread history instead of just thread starter for new sessions
Fixes#4470
* chore: remove redundant comments
* fix: use threadContextNote in queue body
* fix(slack): address Greptile review feedback
- P0: Use thread session key (not base session key) for new-session check
This ensures thread history is injected when the thread session is new,
even if the base channel session already exists.
- P1: Fetch up to 200 messages and take the most recent N
Slack API returns messages in chronological order (oldest first).
Previously we took the first N, now we take the last N for relevant context.
- P1: Batch resolve user names with Promise.all
Avoid N sequential API calls when resolving user names in thread history.
- P2: Include file-only messages in thread history
Messages with attachments but no text are now included with a placeholder
like '[attached: image.png, document.pdf]'.
- P2: Add documentation about intentional 200-message fetch limit
Clarifies that we intentionally don't paginate; 200 covers most threads.
* style: add braces for curly lint rule
* feat(slack): add thread.initialHistoryLimit config option
Allow users to configure the maximum number of thread messages to fetch
when starting a new thread session. Defaults to 20. Set to 0 to disable
thread history fetching entirely.
This addresses the optional configuration request from #2608.
* chore: trigger CI
* fix(slack): ensure isNewSession=true on first thread turn
recordInboundSession() in prepare.ts creates the thread session entry
before session.ts reads the store, causing isNewSession to be false
on the very first user message in a thread. This prevented thread
context (history/starter) from being injected.
Add IsFirstThreadTurn flag to message context, set when
readSessionUpdatedAt() returns undefined for the thread session key.
session.ts uses this flag to force isNewSession=true.
* style: format prepare.ts for oxfmt
* fix: suppress InboundHistory/ThreadStarterBody when ThreadHistoryBody present (#13912)
When ThreadHistoryBody is fetched from the Slack API (conversations.replies),
it already contains pending messages and the thread starter. Passing both
InboundHistory and ThreadStarterBody alongside ThreadHistoryBody caused
duplicate content in the LLM context on new thread sessions.
Suppress InboundHistory and ThreadStarterBody when ThreadHistoryBody is
present, since it is a strict superset of both.
* remove verbose comment
* fix(slack): paginate thread history context fetch
* fix(slack): wire session file path options after main merge

* fix: prune stale session entries, cap entry count, and rotate sessions.json
The sessions.json file grows unbounded over time. Every heartbeat tick (default: 30m)
triggers multiple full rewrites, and session keys from groups, threads, and DMs
accumulate indefinitely with large embedded objects (skillsSnapshot,
systemPromptReport). At >50MB the synchronous JSON parse blocks the event loop,
causing Telegram webhook timeouts and effectively taking the bot down.
Three mitigations, all running inside saveSessionStoreUnlocked() on every write:
1. Prune stale entries: remove entries with updatedAt older than 30 days
(configurable via session.maintenance.pruneDays in openclaw.json)
2. Cap entry count: keep only the 500 most recently updated entries
(configurable via session.maintenance.maxEntries). Entries without updatedAt
are evicted first.
3. File rotation: if the existing sessions.json exceeds 10MB before a write,
rename it to sessions.json.bak.{timestamp} and keep only the 3 most recent
backups (configurable via session.maintenance.rotateBytes).
All three thresholds are configurable under session.maintenance in openclaw.json
with Zod validation. No env vars.
Existing tests updated to use Date.now() instead of epoch-relative timestamps
(1, 2, 3) that would be incorrectly pruned as stale.
27 new tests covering pruning, capping, rotation, and integration scenarios.
* feat: auto-prune expired cron run sessions (#12289)
Add TTL-based reaper for isolated cron run sessions that accumulate
indefinitely in sessions.json.
New config option:
cron.sessionRetention: string | false (default: '24h')
The reaper runs piggy-backed on the cron timer tick, self-throttled
to sweep at most every 5 minutes. It removes session entries matching
the pattern cron:<jobId>:run:<uuid> whose updatedAt + retention < now.
Design follows the Kubernetes ttlSecondsAfterFinished pattern:
- Sessions are persisted normally (observability/debugging)
- A periodic reaper prunes expired entries
- Configurable retention with sensible default
- Set to false to disable pruning entirely
Files changed:
- src/config/types.cron.ts: Add sessionRetention to CronConfig
- src/config/zod-schema.ts: Add Zod validation for sessionRetention
- src/cron/session-reaper.ts: New reaper module (sweepCronRunSessions)
- src/cron/session-reaper.test.ts: 12 tests covering all paths
- src/cron/service/state.ts: Add cronConfig/sessionStorePath to deps
- src/cron/service/timer.ts: Wire reaper into onTimer tick
- src/gateway/server-cron.ts: Pass config and session store path to deps
Closes#12289

When starting a new session via /new or /reset, the token usage fields
(totalTokens, inputTokens, outputTokens, contextTokens) survived from the
previous session via the spread pattern in session init. This caused /status
to display misleading context usage from the old session.
Clear all four token metrics explicitly in the isNewSession block, alongside
the existing compactionCount reset. Also add diagnostic logging for session
forking via ParentSessionKey to help trace context inheritance.
* feat(sessions): add channelIdleMinutes config for per-channel session idle durations
Add new `channelIdleMinutes` config option to allow different session idle
timeouts per channel. For example, Discord sessions can now be configured
to last 7 days (10080 minutes) while other channels use shorter defaults.
Config example:
sessions:
channelIdleMinutes:
discord: 10080 # 7 days
The channel-specific idle is passed as idleMinutesOverride to the existing
resolveSessionResetPolicy, integrating cleanly with the new reset policy
architecture.
* fix
* feat: add per-channel session reset overrides (#1353) (thanks @cash-echo-bot)
