* 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

* refactor: update cron job wake mode and run mode handling
- Changed default wake mode from 'next-heartbeat' to 'now' in CronJobEditor and related CLI commands.
- Updated cron-tool tests to reflect changes in run mode, introducing 'due' and 'force' options.
- Enhanced cron-tool logic to handle new run modes and ensure compatibility with existing job structures.
- Added new tests for delivery plan consistency and job execution behavior under various conditions.
- Improved normalization functions to handle wake mode and session target casing.
This refactor aims to streamline cron job configurations and enhance the overall user experience with clearer defaults and improved functionality.
* test: enhance cron job functionality and UI
- Added tests to ensure the isolated agent correctly announces the final payload text when delivering messages via Telegram.
- Implemented a new function to pick the last deliverable payload from a list of delivery payloads.
- Enhanced the cron service to maintain legacy "every" jobs while minute cron jobs recompute schedules.
- Updated the cron store migration tests to verify the addition of anchorMs to legacy every schedules.
- Improved the UI for displaying cron job details, including job state and delivery information, with new styles and layout adjustments.
These changes aim to improve the reliability and user experience of the cron job system.
* test: enhance sessions thinking level handling
- Added tests to verify that the correct thinking levels are applied during session spawning.
- Updated the sessions-spawn-tool to include a new parameter for overriding thinking levels.
- Enhanced the UI to support additional thinking levels, including "xhigh" and "full", and improved the handling of current options in dropdowns.
These changes aim to improve the flexibility and accuracy of thinking level configurations in session management.
* feat: enhance session management and cron job functionality
- Introduced passthrough arguments in the test-parallel script to allow for flexible command-line options.
- Updated session handling to hide cron run alias session keys from the sessions list, improving clarity.
- Enhanced the cron service to accurately record job start times and durations, ensuring better tracking of job execution.
- Added tests to verify the correct behavior of the cron service under various conditions, including zero-delay timers.
These changes aim to improve the usability and reliability of session and cron job management.
* feat: implement job running state checks in cron service
- Added functionality to prevent manual job runs if a job is already in progress, enhancing job management.
- Updated the `isJobDue` function to include checks for running jobs, ensuring accurate scheduling.
- Enhanced the `run` function to return a specific reason when a job is already running.
- Introduced a new test case to verify the behavior of forced manual runs during active job execution.
These changes aim to improve the reliability and clarity of cron job execution and management.
* feat: add session ID and key to CronRunLogEntry model
- Introduced `sessionid` and `sessionkey` properties to the `CronRunLogEntry` struct for enhanced tracking of session-related information.
- Updated the initializer and Codable conformance to accommodate the new properties, ensuring proper serialization and deserialization.
These changes aim to improve the granularity of logging and session management within the cron job system.
* fix: improve session display name resolution
- Updated the `resolveSessionDisplayName` function to ensure that both label and displayName are trimmed and default to an empty string if not present.
- Enhanced the logic to prevent returning the key if it matches the label or displayName, improving clarity in session naming.
These changes aim to enhance the accuracy and usability of session display names in the UI.
* perf: skip cron store persist when idle timer tick produces no changes
recomputeNextRuns now returns a boolean indicating whether any job
state was mutated. The idle path in onTimer only persists when the
return value is true, eliminating unnecessary file writes every 60s
for far-future or idle schedules.
* fix: prep for merge - explicit delivery mode migration, docs + changelog (#10776) (thanks @tyler6204)
Read the final user/assistant message from session transcripts and display
it in the picker alongside the session update time. Allows quick previews
of what's in each session without opening it.
Server-side filtering backup for client-side session picker search.
Case-insensitive substring match on displayName, label, subject,
sessionId, and key.
Closes#1161
Enable meaningful session titles via priority-based derivation:
1. displayName (user-set)
2. subject (group name)
3. First user message (truncated to 60 chars)
4. sessionId prefix + date fallback
Opt-in via includeDerivedTitles param to avoid perf impact on
regular listing. Reads only first 10 lines of transcript files.
Closes#1161
Ensure 'main' alias is always stored as 'agent:main:main' to prevent
duplicate entries. Also update loadSessionEntry to check both forms
when looking up entries.
Fixes duplicate main sessions in session store.
- Add `label` field to session entries and expose it in `sessions.list`
- Display label column in the web UI sessions table
- Support `label` parameter in `sessions_send` for lookup by label instead of sessionKey
- `sessions.patch`: Accept and store `label` field
- `sessions.list`: Return `label` in session entries
- `sessions_spawn`: Pass label through to registry and announce flow
- `sessions_send`: Accept optional `label` param, lookup session by label if sessionKey not provided
- `agent` method: Accept `label` and `spawnedBy` params (stored in session entry)
- Add `label` column to sessions table in web UI
- Changed session store writes to merge with existing entry (`{ ...existing, ...new }`)
to preserve fields like `label` that might be set separately
We attempted to implement label persistence "properly" by passing the label
through the `agent` call and storing it during session initialization. However,
the auto-reply flow has multiple write points that overwrite the session entry,
and making all of them merge-aware proved unreliable.
The working solution patches the label in the `finally` block of
`runSubagentAnnounceFlow`, after all other session writes complete.
This is a workaround but robust - the patch happens at the very end,
just before potential cleanup.
A future refactor could make session writes consistently merge-based,
which would allow the cleaner approach of setting label at spawn time.
```typescript
// Spawn with label
sessions_spawn({ task: "...", label: "my-worker" })
// Later, find by label
sessions_send({ label: "my-worker", message: "continue..." })
// Or use sessions_list to see labels
sessions_list() // includes label field in response
```
