Jarek Potiuk commented on JENKINS-13174:
----------------------------------------
It seems that the plugin stores "latest revision" separately and compared this
latest revision with the one on server (which change after push). It does not
check if locally anything changed since the last revision was pulled.
> Stop changeset tags from being counted as a change in Mercurial Plugin polling

> Key: JENKINS-13174
> URL: https://issues.jenkins-ci.org/browse/JENKINS-13174
> Project: Jenkins
> Issue Type: Bug
> Components: mercurial
> Affects Versions: current
> Reporter: Neil Kay
> Assignee: Kohsuke Kawaguchi
>
> We have the slave build machines polling Mercurial repositories, using the
> Mercurial plugin, to trigger builds.
> During the Jenkins job, we create and push a tag changeset as part of the
> build process.
> This tag changeset is detected by polling and causing an infinite loop of
> builds.
> I've looked into other options, I notice the notice away from polling to be
> more push activated, which sounds good, but it seems this still relies on
> polling to detect what has changed, so it seems this would still be a problem.
> The other thing that sounded like it may help was "modules" in the Mercurial
> plugin, but this is a huge change to move lots of repositories to put
> everything except the hgtags file into a sub folder and then specify that sub
> folder as a module.
> If tag changesets were ignorred by polling, similar to a change that was made
> to ignore merge changesets, all would be good in the world :)
