From 76e69d9ef729365db1b0f1798f5f8a038d2065fc Mon Sep 17 00:00:00 2001

Subject: [PATCH] Async batch implementation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add find_job checks
Check if should close on all events
Make batch_delay a request parameter
Allow multiple event handlers
Use config value for gather_job_timeout when not in payload
Add async batch unittests
Allow metadata to pass
Pass metadata only to batch jobs
Add the metadata to the start/done events
Pass only metadata not all **kwargs
Add separate batch presence_ping timeout
Fix async batch race conditions
Close batching when there is no next batch
Add 'batch_presence_ping_timeout' and 'batch_presence_ping_gather_job_timeout' parameters for synchronous batching
Fix async-batch multiple done events
Fix memory leak produced by batch async find_jobs mechanism (bsc#1140912)
Multiple fixes:
- use different JIDs per find_job
- fix bug in detection of find_job returns
- fix timeout passed from request payload
- better cleanup at the end of batching
Co-authored-by: Pablo Suárez Hernández <psuarezhernandez@suse.com>
Improve batch_async to release consumed memory (bsc#1140912)
Use current IOLoop for the LocalClient instance of BatchAsync (bsc#1137642)
Fix failing unit tests for batch async
Remove unnecessary yield causing BadYieldError (bsc#1154620)
Fixing StreamClosed issue
Fix batch_async obsolete test
batch_async: avoid using fnmatch to match event (#217)
Batch Async: Catch exceptions and safety unregister and close instances
Fix unit tests for batch async after refactor
Changed imports to vendored Tornado
Async batch implementation fix (#320)
Remove deprecated usage of NO_MOCK and NO_MOCK_REASON
