# Implementation: add-claim-loop-task
|
||
|
|
|
||
|
|
## What was implemented
|
||
|
|
|
||
|
|
### `--claim-loop-task` subcommand (status.py)
|
||
|
|
|
||
|
|
New `--claim-loop-task <name> --task <taskname> [--project P]` command. Uses `_loop_lock` for serialization. Implementation steps:
|
||
|
|
|
||
|
|
1. Checks `.state.loop` exists (untracked → exit 2)
|
||
|
|
2. Scans all loops via `_all_loop_dirs()` — if another running/paused loop owns the task → exit 2 with `task_already_claimed:{other}`
|
||
|
|
3. If self owns the task → exit 0 (idempotent, no re-write)
|
||
|
|
4. If nobody owns it → sets `state["current_task"] = taskname`, writes `.state.loop`, exit 0
|
||
|
|
|
||
|
|
### Runner claim integration (loop-runner.py)
|
||
|
|
|
||
|
|
Step 3.5: After `_find_work` returns a candidate different from `state.current_task`, spawns `status.py --claim-loop-task` as a subprocess with `$AUTOMATON_NO_LOOP_LOCK=1` (same bypass as `_gate`). Non-zero exit → skip tick with `task_claimed_by_other_loop`.
|
||
|
|
|
||
|
|
Step 9.5: After orchestrator subprocess, re-reads task `.state`. If `complete` or `human_intervention` → `state["current_task"] = None` (releases claim).
|
||
|
|
|
||
|
|
## Files changed
|
||
|
|
|
||
|
|
- `scripts/status.py` — added `_claim_loop_task_impl`, `cmd_claim_loop_task`, `--claim-loop-task` arg + dispatch
|
||
|
|
- `scripts/loop-runner.py` — added step 3.5 (claim) and step 9.5 (release) in `cmd_tick`
|
||
|
|
|
||
|
|
## Tests
|
||
|
|
|
||
|
|
10 tests in `tests/test_claim_loop_task.py` covering:
|
||
|
|
- Claim succeeds (no owner), claim refused (other owner), claim idempotent (self owner)
|
||
|
|
- Untracked loop, missing task arg
|
||
|
|
- Paused loop's claim blocks new claim
|
||
|
|
- Self-healing race (refuse, release, re-claim succeeds)
|
||
|
|
- Release on `complete` and `human_intervention`, no release on `implement`
