The cluster timeout configuration default value None is documented to mean
tasks never timeout out. Also the documentation states that the timeout
can be overridden for individual tasks.
With the old implementation the timeout parameter given to async_task was
not honored if the cluster timeout was set to None.
Fixes: #335
The old implementation used count_forever test task that never finishes.
If the timeout implementation does not work in the test, the test never
end and you was required to kill the test runner.
* async is now a reserved word in python3.7
* Rename async function to enqueue
* Rename all async_ functions to enqueue_
* Rename Async class to AsyncTask
* Updates the docs.
If a task fails with an exception, it is retried until it
succeeds. This is contrary to what is said in the documentation: under
the "Architecture" section, heading "Broker" it says that even when a
task errors, it's still considered a successful delivery. Failed tasks
never get acknowledged however, thereby being retried after the
timeout period. See also issues #238 and #194.
This patch adds an option to acknowledge failures, thereby closing
issue #238. Issue #194 would require some more work. The default of
this option is set to `False`, thereby maintaining backwards
compatibility.
The test suite, especially for the brokers, was heavily dependant on the
success of the tests preceeding it to pass. This commit should eliminate
that dependency and allow tests to fail without affecting others.
It also removes the need to cleanup globals manually after a test.
* task now takes an optional keyword `group`
* added result_group() and fetch_group()
* added group column to Success admin
* group column in searchable
* added `name` field to Schedules
* Scheduled tasks take schedule name as group
* added a `timeout` keyword to tasks.
* timeouts now count down instead of up
* `timeout` in task overrides global timeout setting
* added tests for timeout override
* added a test for recycling
* added a synchronous cluster simulation
* added a test for the sync function
* moved signing into its own module
* refactored imports to solve circular import problems stemming from the task module pretending to be a cluster
* added documentation for the new sync option
The core module was becoming too large.
By splitting it in cluster, monitor and tasks it becomes more manageable. It also reflects the documentation structure.
