Make it so that submitting a task to the dispatcher happens as part of the transaction.
this applies to dispatcher task "publishers" which NOTIFY the pg_notify queue
if the transaction is not successful, it will not be sent, as per postgres docs
This keeps current behavior for pg_notify listeners
practically, this only applies for the awx-manage run_dispatcher service
this requires creating a separate connection and keeping it long-lived
arbitrary code will occasionally close the main connection, which would stop listening
Stop sending the waiting status websocket message
this is required because the ordering cannot be maintained with other changes here
the instance group data is moved to the running websocket message payload
Move call to create_partition from task manager to pre_run_hook
mock this in relevant unit tests
Avoid running jobs that have already been reapted

Remove unnecessary extra actions
Fix waiting jobs in other cases of reaping
Introduce build_project_dir method
the base method will create an empty project dir for workdir
Share code between job and inventory tasks with new mixin
combine rest of pre_run_hook logic
structure to hold lock for entire sync process
force sync to run for inventory updates due to UI issues
Remove reference to removed scm_last_revision field
Instead of loading all pending Workflow Approvals in the task manager,
run a query that will only return the expired apporovals
directly expire all which are returned by that query
Cache expires time as a new field in order to simplify WorkflowApproval filter
This optimizes the ActivityStreamSerializer by only getting many-to-many
relationships that are speculatively non-empty
based on information we have in other fields
We run this every time we create an object as an on_commit action
so it is expected this will have a major impact on response times for launching jobs
* Reap jobs on dispatcher startup to increase clarity, replace existing reaping logic
* Exit jobs if receiving SIGTERM signal
* Fix unwanted reaping on shutdown, let subprocess close out
* Add some sanity tests for signal module
* Add a log for an unhandled dispatcher error
* Refine wording of error messages

* Track combined artifacts on workflow jobs
* Avoid schema change for passing nested workflow artifacts
* Basic support for nested workflow artifacts, add test
* Forgot that only does not work with polymorphic
* Remove incorrect field
* Consolidate logic and prevent recursion with UJ artifacts method
* Stop trying to do precedence by status, filter for obvious ones
* Review comments about sets
* Fix up bug with convergence node paths and artifacts
* Only use in-memory cache for database settings
Make necessary adjustments to monkeypatch
as it is very vunerable to recursion
Remove migration exception that is now redundant
Clear cache if a setting is changed
* Use dedicated middleware for setting cache stuff
Clear cache for each request
* Add tests for in-memory cache
* Delay update of artifacts until final job save
Save tracebacks from receptor module to callback object
Move receptor traceback check up to be more logical
Use new mock_me fixture to avoid DB call with me method
Update the special runner message to the delay_update pattern
* Move special runner message into post-processing of callback fields
* Track host_status_counts and use that to process notifications
* Remove now unused setting
* Back out changes to callback class not needed after all
* Skirt the need for duck typing by leaning on the cached field
* Delete tests for deleted task
* Revert "Back out changes to callback class not needed after all"
This reverts commit 3b8ae350d218991d42bffd65ce4baac6f41926b2.
* Directly hardcode stats_event_type for callback class
* Fire notifications if stats event was never sent
* Remove test content for deleted methods
* Add placeholder for when no hosts matched
* Make field default be None, denote events processed with empty dict
* Make UI process null value for host_status_counts
* Fix tracking of EOF dispatch for system jobs
* Reorganize EVENT_MAP into class properties
* Consolidate conditional I missed from EVENT_MAP refactor
* Give up on the null condition, also applies for empty hosts
* Remove cls position argument not being used
* Move wrapup method out of class, add tests
* Remove committed_capacity field, delete supporting code
* Track consumed capacity to solve the negatives problem
* Use more verbose name for IG queryset
* Simple patches to make jobs robust to database restarts
* Add some wait time before retrying loop due to DB error
* Apply dispatcher downtime setting to job updates, fix dispatcher bug
This resolves a bug where the pg_is_down property
never had the right value
the loop is normally stuck in the conn.events() iterator
so it never recognized successful database interactions
this lead to serial database outages terminating jobs
New setting for allowable PG downtime is shared with task code
any calls to update_model will use _max_attempts parameter
to make it align with the patience time that the dispatcher
respects when consuming new events
* To avoid restart loops, handle DB errors on startup with prejudice
* If reconnect consistently fails, exit with non-zero code
