It's broken in weird ways since recently (`:version` not loading,
segfault in test_version.py). Since nobody should be using it anyways,
there is no point in spending time on debugging a tricky issue.
Next step is probably ripping it out completely, but that's a separate
can of worms.
See #4039
The normal PDF.js build only officially supports the latest Chromium, so things
might break every once in a while with QtWebEngine (e.g. #8199, #7335).
Let's instead bundle and recommend the legacy build.

This re-enables the pylint too-many-positional-arguments for the main
application code. It's still disabled for tests because that's how you pull in
pytlint fixtures, and I don't think we want to push people into being creative
with fixtures just to get around that.
When functions are called with many positional arguments the reader has to do
a bit of heavy lifting to figure out in what position a value is being passed,
and it's easier to make mistakes. So I would like to encourage using keyword
arguments for long argument lists.
I've set the `max-positional-arguments` to a completely arbitrary 7, from a
completely arbitrary 5, because there were many more violations under 7. If
like 99% of our functions fit under 7 it's probably fine.
Regarding the exceptions:
* objreg.register: I grepped it and it looks like everything is only passing
the first two args as positional already, lucky!
* `_get_color_percentage`: only one usage of it, but I was in "add directive
comment" mode
* update_3rdparty.py: only one usage, already using kwargs
* pyqtProperty: idk
* commands.py: "its complicated". Many methods in this file map to commands
used in qutebrowser's command mode. In that case it's usual for them to be
called as flags, rather than positional. But it could be complicated to wade
into that, and having one file excluded isn't so bad.
I just searched for qt5 and deleted stuff. EZ.
Will leave on a branch for a bit and see if I feel like testing this at
all, otherwise maybe leave this stuff in here and make it not called.
Not 100% sure that we need to remove all this stuff when we just want
the CI to go green. But tbh if we don't need to make Qt5 releases then
we don't need it. Better to be bold and pull it out than have to work
around it in the future. And we can always revert the commit.
This commit takes a screenshot of the active browser window when an
end2end test fails. When running on CI a zip file of screenshots will be
attached to the run summary as an artifact. When run locally screenshots
will be left in /$TMPDIR/pytest-screenshots/.
The screenshot is of the Xvfb screen that the tests are running under.
If there are multiple windows open it will likely only show the active
window because a) we aren't running with a window manager b) the Xvfb
display is, by default, the same size as the browser window.
I'm not sure if xvfb is used on the Window runs in CI. We could fall
back to trying to take screenshots if not running under xvfb but I'm a
bit wary of an automatic feature that takes screenshots of people's
desktops when running locally. Even if they just to to /tmp/ it might be
surprising. We can change it later if it turns out we need to try to
take screenshots in more cases.
I'm using pillow ImageGrab, the same as pyvirtualdisplay.smartdisplay. I'm
getting the display number from the pytest-xvfb plugin and formatting it
appropriately (pyvirtualdisplay has an already formatted one which is used by
the smartdisplay, but that's not accessible).
Pillow is now a requirement for running the tests. I thought about making
it gracefully not required but I'm not sure how to inform the user with
a warning from pytest, or if they would even want one. Maybe we could
add a config thing to allow not taking screenshots?
I had to bump the colordepth config for pytest-xvfb otherwise pillow
complained that the default 16bit color depth wasn't supported as it
only supports 24bit, see https://github.com/python-pillow/Pillow/blob/1138ea5370cbda5eb328ec949

I'm saving screenshots to a temp dir because I don't want to put them in
my workdir when running locally. I want to clear the directory for each
run so that you don't get confused by looking at old images. I'm not
100% sure about the lifecycle of the process classes though. Eg if we
have two processes they might both try to create the output directory.
I'm using pytest.session.stash to save the directory so perhaps the
lifecycle of the stash will handle that? Not sure.
Ideally the images would be uploaded somewhere where we could click
through and open them in the browser without having to download a zip
file, but I'm not sure how to achieve that.
It would be nice to print in the test logs that a screenshot was saved
and where to. Just so you could copy paste the filename instead of
having to match the sanitized filename against failing test names. But I
don't know how to log stuff from this stage in the pytest lifecycle.
TODO:
* I'm not sure that the screenshot captures the whole browser window?
Maybe the browser windows is bigger than the X11 display?
