When I go to https://build.webkit.org/results/WinCairo-64-bit-WKL-Debug-Tests/r279815%20(689)/results.html then click on the diffs, I get 403 errors. The solution apparently has to do with changing the umask or chmod or something.
The individual files created by the wincairo bots have very restrictive file permissions. We simply unzip the results and host them. The bots (probably buildbot.tac for buildbot-worker) should use umask = 022
We are using that umask any other things to look at? https://github.com/WebKitForWindows/docker-webkit-dev/blob/master/buildbot/WebKit-BuildWorker/buildbot.tac.tmpl#L35
Same issue with this. Bug 223216 – Forbidden to access WinCairo Buildbot sub-directories of layout test results as "403 Forbidden"
Perhaps it should be 0o022, as changed for Python 3 in https://trac.webkit.org/changeset/268935/webkit?
I went ahead and applied the ACL to WinCairo-64-bit-WKL-Debug-Tests/ directory, similar to what's done in https://bugs.webkit.org/show_bug.cgi?id=223216
The test results Alex linked to aren’t 403ing anymore so this looks successful. Should check after more builds before closing it. Thanks for the assist!
