📝 WalkthroughWalkthroughThe change adds same-controller receptor work-unit adoption for dispatched jobs. Heartbeat processing reconnects to work units, replays non-duplicate events, finalizes job status, and fails stale orphaned jobs after a configurable timeout. Startup reaping now targets undispatched jobs. ChangesDispatched Job Adoption

…ller job reattach on restart Key changes: - Extract _transmit_phase() from _run_internal() so run() explicitly calls transmit then _process_phase() — the shared code path used by both normal jobs and adoption. Clarifies that artifacts/ is deleted during transmit so _process_phase always receives a clean private_data_dir regardless of which path calls it. - Add reattach_to_work_unit(): reconnects to a completed receptor work unit after a same-controller restart. Replays events from startpos=0 with counter-skip dedup using a set of persisted counters (not max threshold) to handle out-of-order parallel callback worker persistence. - Fix callback initialization in reattach_to_work_unit: set job_created, safe_env, parent_workflow_job_id to match what BaseTask.run() sets in jobs.py. - Add _receptor_release_work() to adoption finally block with DB-status guard: defers release when job is not yet finalized in DB, preserving the work unit for adoption if the controller is killed between _process_phase completing and BaseTask.run() committing the final status. Fixes the race that left jobs stuck in 'running'. - Fix adoption finalization: when _process_phase raises, finalize the job via the pre-fetched exit_code rather than returning False and looping forever. - Fix detail=None TypeError in _handle_work_error when receptor omits Detail key. - Add send_notification_templates to adoption finalization path. - Consolidate startup/heartbeat job processing into unified per-job loops (reaper.py + system.py): remove UNDISPATCHED_Q, startup_reaping(), undispatched_only; add _process_startup_jobs(), _process_running_jobs(), _startup_reap_undispatched(). - Add per-job exception isolation in adoption/reap loops. - _reap_and_mark_lost_instance: inline loop with explicit adopt/error branch per job; cross-controller adoption plugs into the dispatched branch (AAP-89602). - Move _AdoptionTask to module level (avoid re-executing class body per adoption). Cluster-verified across 9 job scenarios: 4 normal, 1 fail, 1 long (still-running), 1 many-events, 1 mid-flight success, 1 mid-flight fail. All 36 checks pass including pre-kill/post-kill event stream data verification with named markers. SonarCloud fixes and test coverage improvements: - Extract _handle_work_error from _process_phase to reduce cognitive complexity from 18 to under 15 (SonarCloud High finding, L504) - Rename unused params in _AdoptionTask.build_execution_environment_params to _instance/_private_data_dir (SonarCloud Medium findings, L887) - Unit tests (test_receptor_adoption.py): cover _process_phase, _handle_work_error, receptor_config_exists, _get_or_create_private_data_dir, should_update_config FileNotFoundError path, and reattach_to_work_unit internal invariants (callback init, _receptor_release_work call, exception swallowing) - Functional tests (test_tasks_system.py): add 6 new @pytest.mark.django_db tests for reattach_to_work_unit branch coverage — receptor command fails, exit code from Detail string, Detail parse fallback, process phase raises, job already finalized — using real Job DB objects per project convention Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com> Signed-off-by: Hui Song <hsong@redhat.com>
…callback Extract _configure_runner_callback() as the canonical callback factory shared between the normal job path (BaseTask.run) and adoption (reattach_to_work_unit). Previously, BaseTask.run() manually set job_created, safe_env, and parent_workflow_job_id on the callback, while _build_adoption_callback did the same thing independently. Any field missed in _build_adoption_callback would only surface in adoption-specific tests, not in the normal job test suite. Now both paths call _configure_runner_callback(), so the normal test suite (which runs thousands of real jobs) exercises the same initialization code as adoption. Missing or incorrect fields surface immediately in CI. Also fixes adoption finalization to include delayed fields (result_traceback, job_explanation, emitted_events) set by callbacks during _process_phase, matching what BaseTask.run() writes via update_model(**get_delayed_update_fields()).

…O(N events)
Replace the O(N) persisted_counters set with a memory-safe hybrid approach for
large-job safety in production:
safe_threshold: highest counter where all lower counters are also in DB
(contiguous prefix). Skipped with a single integer comparison — O(1).
collision_zone: small set of counters above the threshold that are already in
DB. These exist because parallel callback workers can commit a higher-counter
event before a lower-counter one is flushed. Bounded by JOB_EVENT_WORKERS x
batch size — typically < 20 entries regardless of total job event count.
Memory: O(1) + O(worker_count), never O(N events). A 1M-event job with
contiguous commits has threshold=1M and an empty collision zone — no set at all.
The gap query (Exists + OuterRef) finds the first non-consecutive counter in the
job's event sequence. Everything below is the safe contiguous prefix; everything
above and already in DB is the collision zone.
JobEvent.uuid has no unique constraint, so the callback receiver cannot deduplicate
replayed events — they would be inserted as duplicate rows. The hybrid approach
ensures no event in DB is re-dispatched to the callback receiver.

Replace inline blocking adoption in the heartbeat with adopt_job_async background task, enabling real-time event streaming during controller restart recovery. Key changes: - Add adopt_job_async @task (on_duplicate='discard'): creates its own receptor_ctl, handles timeout check, calls reattach_to_work_unit in a background worker — heartbeat returns immediately - Remove _try_adopt_job: timeout + adoption logic moved into adopt_job_async - _process_startup_jobs / _process_running_jobs: drop ctl param, dispatch adopt_job_async.apply_async for orphaned dispatched jobs - reattach_to_work_unit: remove "still Running -> return False" guard; _process_phase now called immediately regardless of unit state, streaming events in real-time until the EE finishes - Fix exit code: use res.status from _process_phase result instead of re-querying work status after the unit is released (avoids exit_code=1 when the unit is released before the re-check) - Move Exists/OuterRef imports to top-level Django imports block - Add JOB_EVENT_CALLBACK_BUFFER_SIZE = 1000 constant to defaults.py matching the per-worker flush threshold in the callback receiver - Cap collision_zone query at JOB_EVENT_WORKERS * JOB_EVENT_CALLBACK_BUFFER_SIZE to make the theoretical worst-case bound explicit in code Same extension point for AAP-89602: swap reap_job with work adopt + adopt_job_async.apply_async in _reap_and_mark_lost_instance.

But this appears legit. Remove task kwarg unless there is compelling non-obvious reason not to.

Something's not right with the host_map.
This is a pre-existing construct.
Line 492 in c0e1e7e
But I can't find it in the diff. It is added... but it's not removed. That's strange... and bad.
We have several inventory "types", those being constructed, smart, normal. And the way the host queryset is rendered is different for each, and there are a lot of large inventories with scale problems. The existing prior reference worked around this by getting the host map from the inventory data which is a dict made of scalars by that point.
I think you need to re-construct the inventory data (as a dict), and use that instead of instance.inventory otherwise these corner cases will break.
I don't think you need to pass any more data to make this happen. But it does create a performance problem where you are building this large data structure twice in the main data structure. As much as I like the shared callback method, that might mean you have to build it separately in the job re-adoption code path. For that, I think you need to share a new static method that takes script_data as its argument, and the job re-adoption path needs to build that from the instance.inventory separately, because this is not an issue in the main code path, and it's performance-sensitive.

Fixed. Both the normal job path and adoption path now use identical logic for populating host_map.
Before:
- Normal path:
write_inventory_file()read from hostvars script data - Adoption path: Direct Host model query
After:
Both paths call RunnerCallback.configure_for_job() which uses inventory.get_script_data(hostvars=True). The same source is used by the normal path. This ensures both paths respect:
- Inventory types (smart, constructed, normal)
- Enabled/disabled host filtering
- Job slicing parameters
Removed the duplicate host_map population from write_inventory_file() since it's now handled earlier in the execution path.

I do like this method. I like it a lot. But awx/main/tasks/receptor.py is the wrong module for it to live. Best would be in the awx/main/tasks/callback.py, and ideally as a @classmethod to initialize the object.

Done. Moved the callback initialization logic out of receptor.py and into the RunnerCallback class itself

I think this can go top of the file? The callback should very very clearly be low-import.

The inline imports in receptor.py at RunnerCallback and _finalize_job_run are necessary to avoid circular import cycles
Both BaseTask.run() and the adoption path need to commit terminal status, trigger notifications, and emit websocket status. Previously these were duplicated code paths that could drift independently. Extract _finalize_job_run(model, pk, runner_callback, status, extra_fields) into jobs.py and call it from both sites: - BaseTask.run(): replaces the two update_model() calls + events_processed_hook + websocket_emit_status; final_run_hook and raise still follow outside - _finalize_adopted_job: replaces direct setattr+save; passes finished/elapsed via extra_fields since the callback receiver may not set them during replay Normal CI job tests now exercise the same _finalize_job_run the adoption path uses, giving incidental coverage of adoption finalization. Also move _receptor_release_work() from AWXReceptorJob.run()'s finally block to after _finalize_job_run() in BaseTask.run(). This ensures the work unit stays live until the job's terminal status is committed to DB — eliminating the race where a controller kill between release and finalization left a job stuck in 'running' with no adoptable work unit. The previous DB-status guard in _receptor_release_work() was not a real check: status in DB is always 'running' at the finally block because _finalize_job_run() hasn't run yet. The guard is removed; awx_receptor_workunit_reaper remains the fallback for any edge cases where release is skipped.
