Fix Jenkins slave connection dying on vdsm check_merged jobs ------------------------------------------------------------

Key: OVIRT-938 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-938 Project: oVirt - virtualization made easy Issue Type: Bug Components: Jenkins Reporter: Barak Korren Assignee: infra

Something in the vdsm build_artifacs job makes the Jenkins slave disconnect when it is running. This in turn makes the cleanup scripts not run on the slave leaving it dirty enough to make the next job on that slave fail. Example of this can be seen here: http://jenkins.ovirt.org/job/vdsm_master_check-merged-el7-x86_64/692/console Relevant log lines: {code} 21:49:00 Ran 44 tests in 1231.988s 21:49:00 21:49:00 OK 21:49:00 + return 0 21:49:00 sh: [13086: 1 (255)] tcsetattr: Inappropriate ioctl for device 21:49:00 Took 2464 seconds 21:49:00 =================================== 21:49:00 logout 21:49:01 Slave went offline during the build 21:49:01 ERROR: Connection was broken: java.io.IOException: Unexpected termination of the channel 21:49:01 at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:50) 21:49:01 Caused by: java.io.EOFException 21:49:01 at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2353) 21:49:01 at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2822) 21:49:01 at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:804) 21:49:01 at java.io.ObjectInputStream.<init>(ObjectInputStream.java:301) 21:49:01 at hudson.remoting.ObjectInputStreamEx.<init>(ObjectInputStreamEx.java:48) 21:49:01 at hudson.remoting.AbstractSynchronousByteArrayCommandTransport.read(AbstractSynchronousByteArrayCommandTransport.java:34) 21:49:01 at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:48) 21:49:01 21:49:01 Build step 'Execute shell' marked build as failure 21:49:01 Performing Post build task... 21:49:01 Match found for :.* : True 21:49:01 Logical operation result is TRUE 21:49:01 Running script : #!/bin/bash -x 21:49:01 echo "shell-scripts/mock_cleanup.sh" ...
