Description Greg Watson

2011-11-12 17:22:33 EST

I recently received the following exception when trying to delete the workspace. Hudson should handle this situation more gracefully than by delivering a stacktrace.

Status Code: 500

Exception: 
Stacktrace:
java.io.IOException: Unable to delete /opt/users/hudsonbuild/.hudson/jobs/ptp-nightly/workspace/.git/objects/pack - files in dir: [/opt/users/hudsonbuild/.hudson/jobs/ptp-nightly/workspace/.git/objects/pack/.nfs000000000030c02800002a51]

I believe bug 363711 is a dupe of this one.  Workspaces are on an NFS-mounted filesystem if that helps.

Is JGit used for doing the Git work or the native Git executable? I suspect it's JGit (or the JVM) that may hang onto those files for some random time after a Git operation finished.
