[JENKINS-13202] Artifact archiving from an ssh slave fails if symlinks are present #2166

Open timja opened 12 years ago

timja commented 12 years ago

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:

rm -rf stuff
mkdir stuff
cd stuff
touch zzfile
ln -s zzfile aafile
ln -s zzfile bbfile

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.

We have seen this too when we upgraded to 1.456.

This might be related to JENKINS-13280.

bsm_ghs:

I would agree. Please see my suggested patch in JENKINS-13280.

timja commented 12 years ago

brenuart:

The same problem appears during installation of tools like JDK or Maven packaged as tar.gz on a remote Unix slave. The deployment process fails with the same exception.
I tend to agree with the above description:

I also agree with the proposed solution: there is no point in trying to chmod a symlink.

The root of the issue seems to be indeed located in the FilePath class and, as the number of linked issue suggest, tend to affect many plugins or different areas of Jenkins.

Are there any plans to fix this issue in the near future?
Is someone working on it?
Can we help somehow ?

I created a pull request for this, including a trivial change to the original JENKINS-9118 test to expose the bug.

Log:
[FIXED JENKINS-13202] Don't set mtime or mode on symlinks

Previously, the untar code tries to set the last modified time and mode
on every untarred file. However, if the tar contains a broken symlink,
or a symlink that points to a file that has not been untarred yet, the
time/mode setting would fail on the broken symlink.

Symlinks don't have meaningful modified times or modes of their own, so
only set these values on non-symlinks.

Rename the file "a" in the test to expose the bug.

Ok this bug is in the 1.465 version who will be released soon.

timja commented 12 years ago

erwan_q:

Sorry I still reproduce this issue with 1.465
Something is broken in the artifact archiving since few releases now.
My case to reproduce: matrix project
Simple artifact to archive (1 tgz file)
multi platform matrix: solaris, linux, aix
And it's broken ONLY for aix.

I see the same thing on AIX, and also on HP. I also run a matrix job, and the Linux and Sun part of that matrix is fine, but the HP and AIX axises fail with that exact same stack trace.

dreiss:

It looks like 00cf9f43 added a stub implementation of POSIX that doesn't implement getCurrentWorkingDirectory. This is only used on platforms where JNA isn't working (see Util.resolveSymlink).

with regard to "readlink missing on AIX etc." I've added a stopgap fix in this pull request. This doesn't represent a final solution, but might take the heat off things a bit.

Anyone running AIX or HP-UX with some time on their hands, please test the above workaround, and test https://github.com/jenkinsci/jenkins/pull/559 if you are running Java 7.

reechard:

@jglick Jesse, nice work. The job I have set up to track this issue runs successfully with your patch, on both AIX and HP-UX. Thanks!

jglick:

@reechard, @scarytom, others: fix should be in 1.483, please check when you can.

timja commented 12 years ago

erwan_q:

Can you confirm this fix is working with java 1.6 too?
If not do we have to migrate the master or the slave where the process is running on java 1.7?
I have an old slave AIX 5.3 and may be do not support java 1.7...
If the fix impact the master, no problem.

timja commented 12 years ago

reechard:

@erwan_q yes this fix works with java 6. I do not have java 7
On my HPUX OR AIX boxes.

timja commented 12 years ago

jglick:

@erwan_q: the full fix should have no effect on Java 5/6; it only takes effect on Java 7+. However the earlier f50316b should at least avoid the worst symptoms.

@Jesse Glick and others.
I've applied the patch on AIX-6.1 slave (Windows master) Running 1.466.3-SNAPSHOT (i.e. 1.466.2 patched)
http://jenkins-ci.org/commit/jenkins/af9977c1b28c2e212f707ab88b4f2ac561e37e50

However the problem is still occurring. I've got a test job which simply attempts to archive dummy stuff. the result is:

Looks like its failing to find 'readlink'

timja commented 12 years ago

jglick:

@bdellegrazie: for 1.466.x you also need to backport 95c1728.

timja commented 12 years ago

bdellegrazie:

@Jesse Glick and others.

I can confirm that with both patches applied, 1.466.x works successfully on AIX 6.1 with IBM Java 6.
Thanks very much for your help!
Any chance of a LTS build with these patches applied? Or if not, can we ensure that they are included in the next LTS release please?

timja commented 12 years ago

jglick:

@bdellegrazie: I know of no particular process for nominating these patches for a hypothetical 1.466.3. But 1.480.1, the next planned LTS, will have both af9977c and 95c1728 applied (the former in its branch, the latter because that was committed prior to 1.480).

As someone running on a relatively unusual platform (which cannot to my knowledge be easily tested by other Jenkins developers in e.g. VirtualBox), you are urged to help test the LTS release candidates: https://wiki.jenkins-ci.org/display/JENKINS/LTS+Release+Line

I think 1.480.1 RC was built before af9977c was cherry-picked, so ask on the dev list before using the RC, or build your own from the stable branch.

timja commented 12 years ago

nnau:

@Jesse Glick file a separate issue: https://issues.jenkins-ci.org/browse/JENKINS-15682

Is this expected?

If it is, then we have a large performance problem. We currently only have 43 jobs defined, but it is taking well over 2 minutes (!!!) to build the main page. Given the number of log entries that it's logging, I'm only left wondering if this is the root cause of the performance issue.
Other ajax type of requests are being responded too in <250mSec.

@matthiasfraass if there is a regression you or someone with access to an HP/UX machine is going to have to diagnose it. Apparently not only can glibc not be loaded but /usr/bin/readlink is absent as well. Try running UtilTest on your machine, run a debugger, etc.

I suspect a fix of JENKINS-14351 (using JNR) would address this issue. But the recommendation remains to use Java 7 which has a supported way of dealing with symlinks and which Jenkins will use preferentially.

(I really wish this issue would be renamed: issues with missing readlink, as it appears to be the root cause of a number of issues).

I'm running this under WAS 8.0 with the IBM 1.6 JDK - which is not something that I can swap out; it is simply not supported.

I am getting massive performance issues (2 minutes to generate the front page with only 43 jobs) and the SystemOut.log is filled with a trace similar to the above.

I still do not understand the underlying need to differentiate between a real file and a sym link, and hence the need for readlink.

Can not some startup logic be used to test for the presence of readlink and record it's presence and then not attempt to use it if not present? Would certainly stop my logs filling 400Mb ever 2 days.
