Joe McDonnell resolved IMPALA-7993.
-----------------------------------
Fix Version/s: Impala 4.0
Resolution: Fixed
We added code that generates JUnitXML when a CMake command fails. This is
enabled for jenkins.impala.io for the GVO jobs including clang-tidy-ub1604.
That eliminates the need to look through logs for any build issue.
> Fix build and scripts to be more useful to developers

> Got a build failure on a Gerrit patch. The tidy log.txt file is 300 MB in
> size with 3.4 million lines. It contains 87,535 warnings identified by a
> "~~~" squiggle, 122 occurrences of the word "failure", 6947 occurrences of
> "fail", and 35,503 occurrences of the word "error." The bottom of the file
> states "7988 warnings generated." Indeed, there are 1077 occurrences of the
> line "warnings generated" in the build.
> It is not realistic for a human to plow through this stuff looking for the
> one obscure pattern that indicates and actual problem.
> This build is unusually large and verbose for an open source project.
> Some improvements:
> * Separate out normal "narration" (echoing of shell commands) from actual
> error output.
> * Fix the code to eliminate warnings, or turn off the warnings.
> * Turn off the extra checks which we just ignore.
> * Create a script that will grep through the file looking for the actual
> failures, ignoring the "expected" errors and failures, identifying the real
> ones.
> It also appears that the scripts build Javadoc (can't tell for what.) Impala
> is famous for its highly unorthodox use of Javadoc comments; the generate
> Javadoc will be gibberish. Either fix the comments to be Java-doc compliant,
> or stop building Javadoc.
