* Add logic to ansible callback plugin to prevent it from waiting
forever to submit events to Tower
* Lower process recycle threshold for tower callback receiver
* Make recycle threshold configurable
* Properly exit the main callback receiver management process if
the event receiver process is dead so we don't leave dead worker
processes
* Set a configurable maximum number of messages that can be waiting
in a worker process queue before it is skipped instead of filling
up memory on a dead worker process
* Skip over a dead worker process if it's queue is full
* Force restart callback receiver if all queues are dead
* Roll back transaction.atomic with the thought that it is causing
deadlocks in the worker process. Use the old commit_on_success
mechanism with retry logic
* Seperate queue nonblocking expected exception from any other type
of exception that could be encountered on the queue fetch operation
the module and fallback to the older codebase's mechanism. Make sure
we are passing the callback port as a string otherwise it seems to
corrupt the shell
* origin/master:
Add tests for inventory_filters and group_by, fix to convert None to empty string.
