[JIRA] [global-build-stats] (JENKINS-15969) Build Stats Plugin Returns so much data it hangs

Fri, 02 Aug 2013 03:19:32 -0700

I am experiencing this problem.

Jenkins version: 1.473
Global Stats Plugin version: 1.3
Chrome versions, if relevant: 28.0.1500.71

The course of events:

  • installed the plugin, restarted jenkins
  • created 4 graphs, then edited their dimensions, range, etc.
  • reordered the graphs on the page - worked for most of them, but when I tried to move the last one up I got some error (in an alert window)
  • reloaded page - then reloading took so long it crashed the page
  • using task manager in chrome I observed that the memory usage went over 1GB for just that page
  • the developer tools showed a very large json file downloaded for /global-build-stats/api/json?depth=2
  • when that finished, it spawned a huge number of requests to obtain the graph images - those actually killed the page
  • somewhere in between I investigated the files on the server
  • I tried to remove the file global-build-stats.xml, no luck - it gets regenerated
  • I tried to edit it and leave only a few <bsc /> nodes (note that there are literally thousands of <bsc /> nodes having the following template <bsc reference="../bsc[{number}]" />, where {number} seem to be random numbers (up to or over 125), with 7 and 2 being probably the most frequent (not sure if relevant)
  • editing that file didn't seem to fix it (file got regenerated and overwritten)
  • I also tried to clear the data in global-build-stats/jobresults, but nothing changed (the data for the last month seems to be regenerated)

Note that the json returned by global/build-stats/api/json?depth=2 returns that large json which actually contains the same two tables repeated over and over again (hundreds, maybe thousands of times). Also, I requested, as suggested, that deleteConfiguration resource - which returned "ok" (whatever, some short json with "ok" in it), but the chart generation resource still returns the chart image for that same id.
