[JIRA] [build-timeout] (JENKINS-23012) Build-timeout plugin causes builds to slow

[darrel...@gmail.com (JIRA)]

Darrel Vuncannon commented on JENKINS-23012 Build-timeout plugin causes builds to slow I've put my reply in-line with a copy of your questions. My text is dark red to make it easier to follow. Again, thank you for your attention to this. OS of the master node and slave nodes. - Master and slaves are Windows Server 2008 R2 Standard. Outline of your build process. For example, running maven, running gcc, or running other native process. I think whether builds are performed in Java or native processes can affect this problem. - There are 561 defined projects that have built in the past two weeks, so I'll have to generalize. - Our projects are 80 to 90% "free-style software projects", the rest being "multi-configuration projects". - We use Git and Gerrit for source code management, however some projects select "none" and use multiple git repos. - Our build-steps are normally "execute shell" or "execute windows batch command" - Overwhelmingly we use WAF for building C/C++ source files; that's both with licensed compilers and "free" compilers. - For authorization, we use "project-based Matrix Authorization Strategy" with 40 defined users plus anonymous. Some projects also enable project-based security. How much log outputs? I think the size of whole log and the time builds take will be helpful. I think much log outputs may trigger the problem. - Quick survey says... 20,000 to 40,000 lines of text for our most popular projects. - These builds average 25 to 50 minutes; strangely, the quicker projects tend to generate more logs. Can you see what process gets slow in builds? If building processes outputs timestamps, please compare them before and after downgrading build-timeout plugin. If you installed Timestampler plugin, please compare timestamps in console outputs. Timestamps logged with timestampler-plugin may differ from the activity of the building process as they can be buffered and delayed. If you don't have timestamper-plugin installed, you'd better not install that as that plugin also captures log output and may cause the same problem. - Plugin timestamper is installed, but only some projects use it. However, the builds in question are no longer saved because they're so long ago, therefore I cannot examine them with the timestamps. - I do have some data captured in a database about those builds. That's data like job-name, build-number, result, build-duration, and interestingly, excerpts from the logs for failed/aborted builds.
