-------------------------------------
Summary: Artifact archiving from an ssh slave fails if symlinks
are present
Key: JENKINS-13202
URL: https://issues.jenkins-ci.org/browse/JENKINS-13202
Project: Jenkins
Issue Type: Bug
Components: core
Affects Versions: current
Environment: Slave must be a "Unix via SSH" slave. I suspect the
master must be Unix-based also. I tested with both the master and slave on
Linux.
Reporter: David Reiss
When archiving artifacts from a job executed on a "Unix via SSH" slave, if a
symlink is present and archived before its target, the archiving will fail. It
looks like the master is trying to chmod the local symlink (because it has
executable permissions stored in the tar used to do the remote copy), but that
fails because the target doesn't exist yet, and the exception aborts the
archiving. I think the solution is to just not chmod symlinks, since they
don't have modes of their own. This was a regression from 1.455 to 1.456. I
suspect the fixes for JENKINS-9118 are the cause.
To reproduce this problem, install the Jenkins master on a Linux machine and
add a "Unix via SSH" slave that is also a Linux machine. Create a job with the
following build script:
{noformat}
rm -rf stuff
mkdir stuff
cd stuff
touch zzfile
ln -s zzfile aafile
ln -s zzfile bbfile
{noformat}
Restrict this project to build on the slave. Set up archiving for "stuff/*".
Run the job. The job will complete successfully, but archiving will abort
partway though with a stack trace in the console.
