[JIRA] (JENKINS-54346) tee keeps file open

tee keeps file open

Issue Type:	Bug
Assignee:	rsandell
Components:	pipeline-utility-steps-plugin
Created:	2018-10-30 13:39
Priority:	Critical
Reporter:	Szabolcs Tolnai

Using the below pipeline script fails in the second stage and in any subsequent runs until the master or slave isn't restarted.

The error is:
ERROR: Cannot delete workspace...

The script:

stage('first') {
node() {
cleanWs()

tee('output.log')

Unknown macro: { echo 'test' }

}
}

stage('second') {
node()

Unknown macro: { cleanWs() echo 'cleaned' }

}

Marked as critical due to the fact that slave/master restart is required to resolve the issue and allow further runs to wipe the workspace (until tee is used again).

Probably related to this issue: I had a "too many open files" error in linux, and the lsof command revealed thousands of open file descriptors resulting from Jenkins pipeline tee command.

Note that tee is executed in parallel tasks in my case.

A restart of the Jenkins service has temporarily solved the problem.

We just started using tee() in a workflow, and in less than 24h, one agent leaked enough descriptors to hit the per-process limit. Use of tee() in this workflow was fundamental to the workflow itself, so this is a huge blocker for us (considering an agent restart is required to resolve).

Jesse Glick any update on https://github.com/jenkinsci/pipeline-utility-steps-plugin/pull/62 ?

I am neither the author of the patch, nor the maintainer of the plugin.

There is a trivial workaround for some use cases: replace

 
                                                                tee('output.txt') {
  sh 'some command'
}

with

 
                                                                sh 'some command >output.txt 2>&1'

Of course this is not possible if you were redirecting output from multiple nested steps that could not be coalesced.

In our installation(2.176.4) tee on windows nodes works good with workflow-job plugin <=2.25. After upgrade workflow-job plugin to 2.26+ version job with

 
                                                                node('windows')
{
tee {bat ... }
cleanWs()
}
 
                                                            

drops with

ERROR: Cannot delete workspace: Unable to delete '...'. Tried 3 times...

Just running into this today. For I workaround i switched to use powershell as follows:

 
                                                                bat '''
   powershell "cmd /c '.\your.bat' | tee output.txt"
'''
