Jenkins: [reproducible] ssh slave log not available, spinning wheel after upgrading to SSH Credentials 1.4, SSH Slaves 1.2 and disconnecting/reconnecting

XMLWordPrintable

      With a brand new Jenkins 1.532 install, no plugins, I am able to setup a dumb ssh slave fine, and can see the slave logfile when I disconnect/reconnect and click Log. This is using Credentials Plugin 1.4, SSH Credentials Plugin 0.3, SSH Slaves Plugin 0.25

      When I update to use Credentials Plugin 1.8.2 and restart, this process continues working fine. So far so good.

      But when I update to use SSH Credentials Plugin 1.4, SSH Slaves Plugin 1.2 I see a regression – when I disconnect/reconnect, then click on Log to view the slave logfile, I just see a spinning wheel in the browser. I can tell the slave did successfully connect (since I see 1 executor available), but I cannot see any slave log output.

      I can consistently reproduce this issue.

      This is a pretty major issue when used in a virtualized slaves environment where slaves are disconnected, reset, and reconnected, since this makes it very difficult to understand the status of the slaves and to troubleshoot slave connection issues.

          Ok, I cannot reproduce this issue with Jenkins 1.520 but I can with Jenkins 1.521... now to hunt for the culprit commit

          Something is closing the PrintStream of the TaskListener after disconnection and that is disconnecting the stream from the file

          I can no longer repro this issue after upgrading to SSH-slaves 1.4, and after upgrading to Jenkins 1.534. Looks good!

          Thanks!
