[profdata][nfc] Disable several tests on Windows #83907

alanzhao1 · 2024-03-04T21:06:52Z

Several profdata tests pass the byte 012 to printf. This causes these tests to fail when using GnuWin32's version of printf because printf will detect that 012 is the LF character and will prepend the byte 015 (CR) in front of LF.

This change is required after #82711 which bumped the version number.

I'd suggest mentioning in the commit message that this is needed after 16e74fd which bumped the version number.

thanks for figuring out why the test failed and making this change!

I did monitor the post-commit CI and the bots passed (from the green checkmark to the upper left of the commit).

For my information, where do you find the failures for GnuWin32's machine? And did you get a real Windows machine to debug the test failures?

alanzhao1 · 2024-03-04T21:38:33Z

This was detected while attempting to update clang for Chrome: https://g-issues.chromium.org/issues/327446719

I was able to repro this locally on a Windows machine using Chrome's package.py script, which uses GnuWin32.

Note that git bash's printf doesn't suffer from this issue, so you'll need to have lit explicitly use GnuWin32's printf.

The buildbot blamed the wrong change. The breakage is actually due to #83488, which was reverted in aec6a04

Ack! The issue is configuration-sensitive. Thanks again for fixing this!
