[JIRA] (JENKINS-42221) MSBuild parser takes unreasonable amount of time
Title: Message Title Emil Styrke created an issue Jenkins / JENKINS-42221 MSBuild parser takes unreasonable amount of time Issue Type: Bug Assignee: Ulli Hafner Components: warnings-plugin Created: 2017/Feb/21 3:26 PM Environment: warnings plugin 4.59 Priority: Major Reporter: Emil Styrke Parsing a log with the MSBuild parser takes over 10 minutes in severe cases, whereas the GCC parser takes at most 10 seconds on a similar log. I'll admit that the log is rather large (17 Mb), but the performance between GCC and MSBuild differs by a factor of 60. This log is the result of a Pipeline build which makes 14 parallel sub-builds on different compilers and platforms, and one possibility to lessen the severity of this issue would be to be able to run the parser on just the current "node" or "stage" statement in the Pipeline script. This would prevent the MSBuild parser from having to see the gazillion of lines coming from GCC, which it won't recognize anyway. Add Comment

Title: Message Title Ulli Hafner commented on JENKINS-42221 Re: MSBuild parser takes unreasonable amount of time After fixing several issues the MS build parser regular _expression_ seems to be overly complex now. I think this is the problem. You can try to pipe the output of the compile steps into files and use the parser only on the corresponding files too speed up things...

Title: Message Title Emil Styrke commented on JENKINS-42221 Re: MSBuild parser takes unreasonable amount of time Thanks for the reply! I did some benchmarking on the regex, and I found out that adding a beginning-of-line anchor to the first "or" group cuts the running time from 16 seconds to 0.15 seconds in my testcase. I created a PR for the change at https://github.com/jenkinsci/warnings-plugin/pull/86.
