SVN externals no longer trigger SCM Polling builds [message #987113]

Hi,

I have a c# solution which includes several projects that get brought into the solution folder using svn:externals.

My Hudson job is configured to build from the latest SVN sources which includes the externals. The build trigger is set to SCM polling.

When I commit a change in one of the externals projects I expect Hudson to trigger a build on my job. This was working fine a couple of months ago but does not work now. Changes to non-external code trigger as expected.

The only changes I can recall are:

- Hudson upgraded from 2.2 to 2.2.1

- SVN upgraded to 1.7.6 on build server. In Hudson, Subversion Workspace Version changed from "1.6 (svn:external to file)" to "1.7"

- SVN plug-in upgraded to 2.3.4 from 2.3.2 that was bundled with Hudson 2.2.1 (Same behaviour with either version)

As far as I can gather the SVNKit within the SVN plug-in is responsible for checking for changes to svn:externals because SVN itself does not do it. Has this been broken during the recent changes listed above?

Is anyone else seeing this problem - there does not seem to be enough mention of it the internet which makes me think it is just my system!

Thanks

Hi,
I have similar experience. Commit to svn external does not trigger the buid. My configuration is a bit different, though.
Hudson ver: 2.2.0
svn workspace ver: 1.6
svn plugin ver: 2.3.3

So it looks like your previous configuration

Hello,

This is a known issue. There have been some major improvements to the subversion plugin to remove the custom svnkit that hudson was originally using and switch to the unmodified version. Someone in the mailing list has addressed this issue to me. I will try to release the new version today which I believe contain a solution to this.

Thanks,
Steve.

Hi,
I have installed this new version (Hudson Subversion Plug-in 2.3.5). Still the changes in externals are not detected. Moreover, when the build is triggered (manually or via pooling) svn plugin crashes with following error:

I had to get back to svn plugin 2.3.4, at least I can checkout sources. ANy idea why it does not work? My Hudson version is 2.2.0 place in Tomcat 6.

Is this still an open issue? I'm having the same problem with hudson 3.0.0 and svn plugin 2.3.6-h-1.

All the /var/lib/hudson/jobs/"myjob"/svnexternals.txt has is

<?xml version='1.0' encoding='UTF-8'?>

hmm, I thought I had resolved these issue in 2.3.6. Are you seeing the stack trace issue or the svnexternal polling issue?

Additional info.

I had original evaluated hudson 2.2.1 and had the same problem. I found that downgrading to 2.2.0 worked. I think it was related to the fact that our svn repositories are 1.6. From what I remember I read something about 2.2.1 using different version of svnkit whatever that is.

Hi,

Just to confirm, polling of externals is not working for me either (plug-in 2.3.6, Hudson 2.2.1).

Hi,

It does not work for me either. None of the following versions work: 2.3.3, 2.3.4, 2.3.5, 2.3.6. Moveover, I got "authentication cancelled" exception while checking out externals now and again, which is extremely annoying. If you try to run the build again and you are lucky it will be checkout successfully. svnexternals.txt file is always empty.

We workaround this by explicitly listing every external as an svn location in the job.
Its a pain because we have a lot of externals. But it works

Douglas, Sorry for the delay on this fix. The latest subversion plugin (2.3.7 and 2.3.7-h-1) has a good solution for this issue.

K Z, Please check out the wiki page: http://wiki.hudson-ci.org/display/HUDSON/Subversion+Plugin#SubversionPlugin-TroubleShooting for more information on that exception.

@Douglas Moore
Thanks, your workaround works! Once all credentials are saved in subversion.credentials file(template in my case) via explicit listing all externals, you can remove them from checkout locations.

@Steve Christou
Provided solutions didn't help, however, Douglas provided valid workaround. Is it possible to fix it somehow in plugin ?

Regards!

BTW
In 2.3.7 pooling externals works correctly as long as credentials are explicitly listed for each external in subverson.credentials file. Otherwise I got well known authentication cancelled exception on pooling.

Also after a few hours trying to figure out the authentication cancelled exception, I found out the real reason why that occurs. When the svn plugin fails to find a version of subversion.credentials file, or any form of authentication(global or system authentication) it will throw that exception. In the case above, when it uses DefaultSVNAuthenticationManager, it goes to ~/.subversion to locate any authentication. I will try resolving this issue on next release.

I'm not understanding all the details here. I'm not familiar with the file subversion.credentials. I have hudson.scm.SubversionSCM.xml which was generate when I tested my credentials via http://localhost:8080/scm/SubversionSCM/enterCredential

With the 2.3.7 plugin is there another step to make polling work with the externals?

Sorry I should have been clearer with the response. The exception that is occurring (see k z's stack trace with authentication cancelled), is because it failed to find the subversion.credentials, the hudson.scm.SubversionSCM.xml, or the ~/.subversion/auth folders. The subversion.credentials file is svn credentials for each job (If credentials for a job are different than others), the hudson.scm.SubversionSCM.xml file is for hudson global credentials (used across multiple jobs), and the ~/.subversion/auth is used globally across the entire computer. Some people have had trouble storing credentials in the subversion.credentials or the hudson.scm.SubversionSCM.xml files. If hudson can't find the necessary credentials file, it will throw the authentication cancelled exception. I updated the error message to state that credentials were not found, which should be in the next release.

With the svn externals, I found that creating a new job and doing a fresh checkout actually helps with finding all the necessary externals information.

Steve,

When credentials are saved and the job has cascading project, subversion.credentials file of that cascading job is updated, not the job you are modifying directly. Anyway, what credentials are used to checkout externals? It looks as if credentials used to checkout externals are not the one (or missing) used for checkout main project now and then. Sometimes explicit saving credentials for each external is necessery. What if project is stored on server A and its externals are pointing to different servers (yes, not just repo but entire server) B,C and D? In such case with V2.3.7 checkout works successfully, but pooling logs shows authenticaion cancelled exception on evey external from server A. When credentials for those externals are saved explicitly in subversion.credentials exceptions go away. Could you also add username used in authentication process to the error message? This should help us out a lot with troubleshooting.

Regards!
