Hi, I made an experiment to see if we should enable sanitizers in CI, by default. Essentially, how much we would slow down integrations and what would be the tests pass rate. Short answer is that, currently, it is not an option, but I produced some data, if someone is interested, please keep reading
Platform: Linux Ubuntu_16_04 (gcc-x86_64) DeveloperBuild, OutOfSourceBuild, QtLibInfix, QtNamespace, BuildExamples, Documentation GCC 5.4 (yes, it is quite old) CPU count = 4 Build qt/qtbase a6546a56fa978bc9ed63203b4ef547adcfd59408 (3/5 completed) State Features Duration ------- --------------------------------- --------- Done Normal build 28min1s Done ConfigureWithAddressSanitizer 35min47s Done ConfigureWithThreadSanitizer 42min44s Error ConfigureWithMemorySanitizer 0min55s Error ConfigureWithUndefinedSanitizer 4min35s Test qt/qtbase a6546a56fa978bc9ed63203b4ef547adcfd59408 (1/5 completed) State Features Duration ----------- ------------------------------- --------- Done Normal build 51min59s Error ConfigureWithAddressSanitizer 1h9min57s Error ConfigureWithThreadSanitizer 1h49min8s Cancelled ConfigureWithMemorySanitizer Cancelled ConfigureWithUndefinedSanitizer At first, I could not even build qtbase, only after applying this https:// codereview.qt-project.org/#/c/208359/ I managed to fix linking issues. Sadly ConfigureWithMemorySanitizer and ConfigureWithUndefinedSanitizer failed to build and I had no immediate idea how to fix them so I ignored the problem. The logs from the tests execution are big. Quite a lot of issues were found and some were definitely valid. If you look into them, remember that some tests failed, therefore they could potentially produce an odd outcome. Interesting part of logs are here: Filename: logs.tar.gz Filesize: 4.29 MB Download link: https://filesender.qt.io/?vid=3775e69f-3d64-f5a9-a225-00003c357692 The file is available until 07-11-2017 after which it will be automatically deleted.
