Description Fujii Hironori 2021-03-15 14:38:37 PDT
Forbidden to access WinCairo Buildbot sub-directories of layout test results as "403 Forbidden"

Slack discussions: 

@Aakash Jain: Why does WinCairo test result sub-directories say "403 Forbidden"? For example, https://build.webkit.org/results/WinCairo-64-bit-WKL-Release-Tests/r273718%20%28288%29/canvas/

Other builders can show the sub-directories. Only WinCairo-64-bit-WKL-Debug-Tests and WinCairo-64-bit-WKL-Release-Tests can't show. https://build.webkit.org/results

Aakash Jain
I'll check. (edited) 

Aakash Jain
@fujihiro Please check if your bots have umask = 022 in their buildbot.tac file. All our bots use that. It is for setting the file permissions.

Stephan Szabo
It does appear to have that on the two bots above.
usepty = 0
umask = 022
maxdelay = 300

Aakash Jain
not sure then.
Maybe you can download the zip files from https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/, unzip them locally and see file permissions, and then do same thing for some other queue and compare them.

Stephan Szabo
Downloading the latest GTK release tests zip and the WinCairo release tests zip to my mac, the base permissions on say "canvas" are the same drwxr-xr-x, but the GTK one has the "@" for extended attributes.

Stephan Szabo
Asking ls -@, it seems like it's a com.apple.quarantine on the directories in the GTK one.

Stephan Szabo
I'll continue poking at it, but for @fujihiro since it's not going to be first priority, for now, you'll probably need to grab the zip for the results and uncompress it locally.

Thank you, @Aakash Jain and @Stephan Szabo . But, I don't see such @ on my Mac. Why?
fujii@fujiis-Mac-mini $ ls -dl@ gtk/canvas wincairo/canvas
drwxr-xr-x  3 fujii  staff  96 Mar  2 11:13 gtk/canvas/
drwxr-xr-x  3 fujii  staff  96 Mar  2 12:07 wincairo/canvas/

Stephan Szabo
Hmm, interesting - I wonder if it depends on how it was uncompressed. But, you are also seeing rwxr-xr-x for both, so at least that's the same.
Comment 1 Fujii Hironori 2021-03-15 14:42:02 PDT
WinCairo is using 'zipfile' Pytnon module to create the zip files, while GTK, WPE and AppleWin are using 'zip' command.

GTK' zip file has entries of directories and a extra metadata 'ux: Unix Extra Type 3'.

zipdetails of WinCiaro

I created small test-result-archive.zip files by invoking test-result-archive script on my Windows and Linux.
And, invoked zipdetails command for both zip files.

python .\Tools\CISupport\test-result-archive archive --platform=wincairo --release

python Tools/CISupport/test-result-archive archive --platform=gtk --release

Comment 5 Fujii Hironori 2021-03-15 16:59:24 PDT
I unzipped zip files of GTK and WinCairo with 022 and 077 umasks.

$ umask 022
$ unzip gtk.zip -d gtk-022
$ unzip wincairo.zip -d wincairo-022
$ umask 077
$ unzip gtk.zip -d gtk-077
$ unzip wincairo.zip -d wincairo-077
$ ls -dl {gtk,wincairo}-{022,077}/canvas
drwxr-xr-x 1 fujii fujii 512 Mar 16 05:26 gtk-022/canvas/
drwxr-xr-x 1 fujii fujii 512 Mar 16 05:26 gtk-077/canvas/
drwxr-xr-x 1 fujii fujii 512 Mar 16 08:53 wincairo-022/canvas/
drwx------ 1 fujii fujii 512 Mar 16 08:54 wincairo-077/canvas/

WinCairo's sub-directories are affected by umask.
Comment 6 Fujii Hironori 2021-03-15 17:12:29 PDT
Hi, Aakash.
Because WinCairo's zip files don't contain Unix permission information, the sub-directories are affected by umask of Buildbot controller.
Could you address this issue in the server side?
Comment 7 lingho@apple.com 2021-07-16 16:49:04 PDT
I added "nginx" to group ACL for the WinCairo-64-bit-WKL-Release-Tests directory on build.webkit.org so nginx would be able to read these files without POSIX permission. So we don't have to worry about umask or lacking of UNIX permission for Windows generated files.

Thank you very much.
