[JIRA] Updated: (HUDSON-4722) Hudson serializes AccuRev pops

Hudson issues mailing list

     [ http://issues.hudson-ci.org/browse/HUDSON-4722?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

sowens01 updated HUDSON-4722:
-----------------------------

    Attachment: AccurevSCM.patch

We've had a chance to look at the code, and I believe we were able to determine the problem. We've run it through what tests we could think of, and it fixes the problem with no ill effects that we can find. I've attached a patch file of the changes. Let me know if there's anything else we can do to help.

> I was checking on a number of builds that I have just converted over to hudson.
> The code base is quite large (3 GB), so it takes quite a while to get the code
> from AccuRev. From the hudson main page it looked as though all the builds had
> started, but when I actually check the build directories, only one was being
> populated. Checking the job logs, the one that was being populated had a log
> file that showed content being populated in the directories. One of the other
> jobs was at the "populating workspace" message in the log, and the other was at
> the "Authenticating" message.
> I waited a number of minutes for the first job to finish populating. Shortly
> after completion of the first populate, one of the other jobs started populating
> the build directory. Once that one completed populating, the last job started
> populating the directory.
> All the jobs are set up to poll AccuRev at the same time using the same user,
> and build the code if changes in the selected stream are found (also the same
> across all the jobs).
> Is there any reason why the populating of the workspace is done in a serial
> fashion? I had these set up as a cron job before converting to hudson, with the
> same configuration (same user populating different directories at the same time,
> etc) and never had to serialize the builds.
> Given the size of the code base, this could have a negative impact on the
> performance of our already lengthy builds.
