[JIRA] [subversion] (JENKINS-17616) Performance issue with Subversion plugin - trigger build on SVN commit takes too long

[r.berg...@openium.fr (JIRA)]

Richard Bergoin edited a comment on JENKINS-17616 Performance issue with Subversion plugin - trigger build on SVN commit takes too long We were having a similar issue after 1.43 -> 1.54 plugin upgrade : our post-commit hook was during from 2 minutes to 5 minutes... and sometimes the job ended before the commit... We have 75 jobs with 1 svn location, and each uses two or more externals that are common of multiple repositories (some jobs are also using same location to a trunk). I've patched the doNotifyCommit method and our post commit now is around 20 seconds The issue is in the UUID determination method that makes an svn call (https in our case) and repeat this call for each locations. I have just add a simple "cache" map that prevents newer calls on already gathered UUIDs. Here is the pull request : https://github.com/jenkinsci/subversion-plugin/pull/59 EDIT to be more precise on results (20 seconds were measured at client side, including upload commit time, at server side, it lower : 11 seconds) : with UUID caching : Dec 12, 2013 9:41:35 PM FINE hudson.scm.SubversionRepositoryStatus Starting subversion locations checks for all jobs Dec 12, 2013 9:41:37 PM FINE hudson.scm.SubversionRepositoryStatus Scheduling the immediate polling of hudson.model.FreeStyleProject@25a598f5[test-job] Dec 12, 2013 9:41:37 PM FINE hudson.triggers.SCMTrigger Scheduling a polling for hudson.model.FreeStyleProject@25a598f5[test-job] Dec 12, 2013 9:41:37 PM FINE hudson.triggers.SCMTrigger scheduling the trigger to (asynchronously) run Dec 12, 2013 9:41:42 PM INFO hudson.triggers.SCMTrigger$Runner run SCM changes detected in test-job.
