`./wpt run firefox path/to/someTest` doesn't run tests when Firefox is installed via Snap about wpt

[gsnedders]

What happens if you pass --log-mach - --log-mach-level debug to get more output?

This runs to completion for me:

@gsnedders is using macOS, btw.

So it's simply not managing to start Firefox… which is almost certainly going to be a Firefox bug, and not a WPT bug. cc @jgraham @whimboo

If you run it with --no-headless, does it still fail? Heck, does /usr/bin/firefox about:blank work at all?

[whimboo]

@mbrodesser-Igalia which version of Firefox are you running? Is that one that got installed via Snap?

The logs show that Browser exited with return code -15 which means that after the around 70s geckodriver kills Firefox because no connection could be made. Would you mind running it again with the --webdriver-arg="-vv" argument included? Maybe this gives an idea what's broken when opening Firefox. Maybe try without headless as well.

It still fails with --no-headless, with a "Profile Missing" error: "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

/usr/bin/firefox about:blank works.

@mbrodesser-Igalia which version of Firefox are you running? Is that one that got installed via Snap?

@whimboo to generate the logs for the previous comments, the default channel was used, which is supposed to be Nightly. Version: 123.0a1 (2024-01-17) (64-bit). That, AFAIR, was not installed via Snap.

However, with the release channel, the test still fails:

That one uses Firefox 122.0 (64-bit).

The logs show that Browser exited with return code -15 which means that after the around 70s geckodriver kills Firefox because no connection could be made. Would you mind running it again with the --webdriver-arg="-vv" argument included? Maybe this gives an idea what's broken when opening Firefox. Maybe try without headless as well.

No-headless with release fails too:

[whimboo]

Ok, so the last log is actually helpful. As I can see you indeed use the snap version of geckodriver and Firefox.

The failure here seems to be with loading the libcanberra-gtk-module.so module because GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported. Whereby the comments on this bug tell that it is harmless. Mind checking comment 2 on this bug if that still shows the same problem?

[whimboo]

Oh wait... actually I just saw: /usr/bin/firefox --marionette about:blank -profile /tmp/tmpkrcbpmjo. This won't work because Firefox cannot reach this profile folder because it's outside of the locations the Firefox Snap package can access.

Can you please try with a Firefox and geckodriver build as downloaded from mozilla.org? If my theory is right we need Snap support in wptrunner.

[mbrodesser-Igalia]

@mbrodesser-Igalia which version of Firefox are you running? Is that one that got installed via Snap?

@whimboo to generate the logs for the previous comments, the default channel was used, which is supposed to be Nightly. Version: 123.0a1 (2024-01-17) (64-bit). That, AFAIR, was not installed via Snap.

@whimboo be reminded that e.g. #44321 (comment) was generated with the default channel (Nightly). However, the corresponding logs show

 0:10.70 INFO Application command: /usr/bin/firefox --marionette about:blank -profile /tmp/tmpiky3eec5

which isn't Nightly. That might be a separate issue from the potential one with Snap.

That is, it indeed worked with the non-Snap version.

[whimboo]

@whimboo be reminded that e.g. #44321 (comment) was generated with the default channel (Nightly). However, the corresponding logs show

Right. We diverged a bit from the original issue. So most likely the problem is somewhere in this Firefox class and the binary under /usr/bin/firefox is inappropriately detected as Nighly:

wpt/tools/wpt/browser.py

Line 197 in 34dd07e

class Firefox(Browser):

If you would have the time and could test I would appreciate. I don't have a Linux system setup using the Snap Firefox package, and @jgraham is away at the moment.

@whimboo: are you using Ubuntu with Snap support? If so, one can install Firefox from mozilla.org and the Snap package, switching via the $PATH variable.

[whimboo]

No, I'm on MacOS and as such cannot easily test this scenario.

[mbrodesser-Igalia]

@whimboo let's deal with the Snap- and Nightly- issues separately: #44585.

[mbrodesser-Igalia]

No, I'm on MacOS and as such cannot easily test this scenario.

Sorry, there are more urgent issues I currently need to work on. Consider installing a VM with Ubuntu.

[whimboo]

No worries it might have to wait then until @jgraham is back. I'm not really working on wptrunner but trying to help with investigations. Thanks for filing!
