Description Matej Kollar 2014-08-14 13:57:24 UTC

Description of problem: When scheduled lots of tasks in async, we occasionally get into "unresponsiveness" issue. To avoid/workaround this, we can not do async things and just wait for the tasks and do things one by one.


How reproducible: nondeterministic

Steps to Reproduce:
1. import multiple larger Red Hat repos

Actual results:
  machine stops responding

Expected results:
  ...

Comment 1 RHEL Program Management 2014-08-14 14:03:05 UTC

Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.

Comment 3 Tomas Lestach 2014-08-14 14:21:16 UTC

By specifying a max. number of parallel tasks, we may reduce the sat6 load. By setting it to '1', the tasks would be run one by one.

Comment 4 Grant Gainey 2014-08-14 14:46:13 UTC

Yeah, that was my thought as well - lets us put it under user-control, too.

Comment 5 Matej Kollar 2014-08-15 17:48:01 UTC

First take at this...

Comment 6 Matej Kollar 2014-08-18 14:53:39 UTC

Extend code so it is accessible...

Comment 7 Grant Gainey 2014-08-22 17:41:10 UTC

Need this for GA - running as-asynch-as-possible tends to cause unpredictable behavior in Sat6, customers will need to be able to throttle

Comment 9 Grant Gainey 2014-09-03 17:49:36 UTC

DEVELOPER VERIFIED:

1) start with a Sat6 that has its orgs and manifests, which has not sync'd any Red Hat content yet, and a channels.csv that has multiple Red Hat channels.
2) hammer import repository-enable --synchronize --wait
3) In the UI, go to <sat6>/katello/sync_management and Expand All
4) Note that *all* the repositories have sync-tasks started

Next:

1) start with a Sat6 that has its orgs and manifests, which has not sync'd any Red Hat content yet, and a channels.csv that has multiple Red Hat channels.
2) hammer import repository-enable --synchronize --wait --no-async
3) In the UI, go to <sat6>/katello/sync_management and Expand All
4) Note that at any given moment, only one repository is synchronizing, and that a new one starts when the first finishes.

This was delivered with Satellite 6.0 which was released on 10 September 2014.
