possible trouble with hue-light plugin

[Tom Brus]

Hi All,

We had an issue here that I would like to mention. I did not have time to sort out the exact details, so I will just have some vague info and suspicion. Maybe it rings a bell for someone to act on it. 

• The first thing we noticed was that our main build was not producing any deliverables anymore, even on green builds.
  
• Investigation showed that all the post build actions had vanished...
  
• I checked the actual config.xml file on the disk: it contained the post build actions as expected, no problem
• huh, so jenkins did not read the config correctly?
• restart jenkins.... still no post build actions in the web interface
• I dug out that same config from backups over the past few days
• I noticed it had exploded from 11k to 324k a few days back
• a quick diff showed that the hue-light plugin had dumped a shedload of xml in my config file
• huh, more then 300k of config xml to just turn on a light?!?
• one of my colleagues had been playing around with some hue lights for some weeks but that seemed to work correctly
• and the xml config explosion was only a few days back
• I checked the config history from the backup, the hue plugin section in the config was first a modest 9 lines and then suddenly exploded to a whopping 5000 lines
• a massive "<lightController>" entry was added to the config of the hue plugin.
• as far as we know there was no manual action at the time of the confg.xml explosion
• what else could re-write the config.xml file?

The result was that jenkins got lost in the massive xml (or there was an xml error in there, I did not check all 5000 lines!) and jenkins was missing all of our post actions.

We needed to get the system in good order again quickly, so I restored a config.xml from a recent backup and restarted jenkins. The post actions have returned and life is good again (without the hue light feedback of course :-(....).

Any bells ringing for anyone?

We will probably try the hue plugin once again, carefully... 

I will keep this list posted with further experiences.

Cheers,

Tom
