Devin FoleyandPaperclip	aec80cbc8c	fix(server): keep workspace compaction out of the startup sweep (#16328) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - When the server starts, `/api/health` answers "starting" until startup recovery finishes, and deploy tooling waits for "ok" > - Startup recovery waits for the first sweep of the terminal-workspace worker > - #16304 added workspace compaction to that sweep. Compaction walks worktrees, runs Git, and deletes dependency trees, and it re-checks every eligible workspace after a restart > - Compaction is never needed to serve requests, so it should not delay readiness > - This pull request skips compaction in the startup sweep only; later sweeps compact as before > - The benefit is that a compaction backlog cannot make a restart slower ## Linked Issues or Issue Description Follow-up to #16304. **What existing behavior does this improve?** Server startup time after #16304. **Current behavior** `await terminalWorkspaceWorker.ready` blocks the readiness flip until the first terminal-workspace sweep ends. That sweep compacts every eligible workspace in its page. The per-cycle compaction memo is in memory, so after each restart every eligible workspace is walked and checked with Git again, and any directories found are deleted before the sweep ends. **Proposed behavior** The first sweep skips compaction. Pending compactions keep their deadlines, so the worker wakes and a later sweep compacts them. **Reason and benefit** Readiness depends only on work that is needed to serve requests. On one measured instance the first sweep took 5–8 s with compaction; with a larger backlog, compaction could add seconds per workspace. **Breaking changes** None. Compaction happens one sweep later after a restart. ## What Changed - `sweepTerminalWorkspaces(limit, signal, { compact })`: `compact: false` skips compaction for that sweep and keeps each pending compaction deadline. - `registerTerminalWorkspaceWork` passes `compact: false` to its first sweep (the one readiness waits for) and `compact: true` after that. - `server/src/index.ts` forwards the option through the logging wrapper. - `doc/DEVELOPING.md`: the compaction section says the startup sweep never compacts. ## Verification - `pnpm exec vitest run src/__tests__/terminal-workspace-work.test.ts src/__tests__/execution-workspace-compaction.test.ts src/__tests__/workspace-compaction.test.ts` (in `server/`): 35 passed. - New: the worker passes `compact: false` only to the startup sweep and `compact: true` to the next one. - New: a sweep with `compact: false` leaves the files in place, the compaction deadline stays due, and the next sweep compacts. - `pnpm typecheck` in `server/`: passed. ## Risks - Low risk. After a restart, compaction runs a few seconds later than before. Archive behavior does not change. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), 1M context, through Claude Code with tool use (shell, file edits, test runs). ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [ ] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>	2026-10-14 15:27:28 -07:00
DottaandPaperclip	7c016c049b	perf(workspaces): wake terminal cleanup from committed changes (#16282) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents use execution workspaces to retain their files and Git branches. > - A reaper closes eligible workspaces after their task tree is terminal. > - The reaper scanned every heartbeat tick and read Git before cheap eligibility checks. > - Permanent scans also query idle databases when no cleanup work exists. > - This pull request wakes cleanup after transaction settlement and restores bounded work at startup. > - The benefit is fewer scans while fresh cleanup guards continue to protect retained work. ## Linked Issues or Issue Description Related work: Refs #13619, Refs #11753. Those PRs bound scans or back off unchanged candidates. This PR uses the transaction work coordinator to remove the permanent reaper tick. It overlaps their early terminal-state filtering but does not change their runtime restart behavior or introduce a second Git scheduler cache. **What existing behavior does this improve?** Terminal workspace cleanup and Git inspection for workspace detail reads. **Subsystem affected** Server orchestration, execution workspaces, and idle sleep admission. **Current behavior** The heartbeat tick scans workspace candidates every thirty seconds. It runs Git before rejecting nonterminal trees, cooldowns, and active runs. Display inspections expire after five seconds. **Proposed behavior** Recover workspace rows in bounded startup pages. Wake after relevant issue, workspace, and pull-request work-product transactions settle. Schedule the terminal tree cooldown or a five-minute eligibility retry. Back off unchanged candidates across unrelated wakes, and invalidate their backoff after relevant committed changes. Park empty and nonterminal-only lanes. Reuse display inspections for thirty seconds. Read fresh Git before destructive cleanup. **Reason and benefit** Avoid recurring database and Git work when no cleanup is possible. Retain transaction admission holds, restart recovery, and fresh deletion checks. Retention eligibility can wait for the next host wake; active and failed recovery work still blocks sleep. **Breaking changes** No schema or API shape changes. Display Git state can lag by thirty seconds. Cleanup eligibility retries can take five minutes. ## What Changed - Add a terminal-workspace worker to the existing transaction work coordinator and scheduler. - Signal relevant writes before mutation on the owning transaction. Outer transaction settlement wakes cleanup. - Derive cooldown deadlines from the full company-scoped terminal task tree. Continue bounded recovery pages without a permanent sweep. - Bound unchanged candidate inspections to five minutes, retain at most 256 entries, and invalidate affected entries with scoped transaction hints. Repeated wakes preserve the earliest inspection deadline. - Collect deadlines from task trees already read by bounded pages. Restore the cursor after a failed page and rescan commits received during a rotation. - Check terminal state, cooldown, and active runs before Git. Preserve lifecycle locks, generation fences, and fresh final checks. - Keep failed or incomplete recovery visible to idle admission. Preserve the passive retention exception. - Extend the bounded display cache to thirty seconds and document the scheduling and wake limits. ## Verification - Focused workspace, coordinator, cache, and local sleep suites: 111 tests passed with real local PostgreSQL and Git worktrees where applicable. - Final worker, display cache, and local sleep suites: 28 tests passed. - The regressions prove three ineligible workspaces invoke zero Git scans, cached clean display state cannot remove new untracked files, and real producer notifications wait for outer transaction settlement. - `pnpm -r typecheck` and `pnpm build` passed locally. Map and module-boundary checks passed. - Work-product and sleep-safety suites: 221 tests passed. Reopen and issue-tree control suites: 46 tests passed. Final backoff, workspace, worker, and work-product suites: 87 tests passed. - Final workspace and worker suites: 81 tests passed. Deadline selection performs zero database reads. A failed full page retries its unread terminal workspace before recovery can park. - Full CI coverage passed on head `2c397970f7`: general tests, serialized server suites, runner verification, E2E shards, typecheck, build, and the final verification gate. The duplicate serial local `pnpm test:run` was stopped after full CI coverage passed; it is not reported as a completed local pass. - Greptile: 5/5 with both findings resolved. The security scan also passed. No failing or pending PR checks remain. ## Risks - Display state can be stale for thirty seconds. Destructive guards bypass the display cache. - Undelivered or otherwise ineligible terminal work retries after five minutes instead of each heartbeat tick. - Transaction signals cover the owning `createDb` scope. Direct SQL and independent server processes require startup recovery. - Local cooldown timers are maintenance hints. They do not establish an external wake alarm or whole-instance sleep safety. Existing blockers remain in force; failed bounded recovery keeps the host awake. ## Model Used OpenAI GPT-6, model ID `gpt-6`, through Codex. Reasoning, repository inspection, shell execution, and browser tools assisted the change. The runtime does not expose the context-window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>	2026-10-14 08:28:45 -05:00
