I've determined this requires both (a) flatpak, and (b) a non-English locale to reproduce. With Tech Preview:
LANG=es_ES.utf8 flatpak run org.gnome.Epiphany.Devel -p
However @alatiera reports that's not enough to make it crash for him. He doesn't see the crash unless he sets some random environment variable to include a UTF-8 character, e.g. FOO="📦\$"
.
There are no web process crashes in coredumpctl because the web process is not actually being launched. I missed this very important information from the first comment:
(epiphany:82): epiphany-WARNING **: 11:14:37.327: Web process crashed
flatpak-spawn: Invalid byte sequence in conversion input
Try "flatpak-spawn --help" for more information.
"Web process crashed" is a lie, WebKit reports a web process crash whenever the connection to the web process closes unexpectedly, but a crash is not the only reason that could happen. In this case, it happens because flatpak-spawn quits.
from org.gnome.epiphany.
Oh and this very important tidbit at the top of the log:
(process:2): Gtk-WARNING **: 11:23:25.510: Locale not supported by C library.
Using the fallback 'C' locale.
That's not good.
from org.gnome.epiphany.
P.S. Workaround is to run with WEBKIT_FORCE_SANDBOX=0 to disable the flatpak-spawn subsandboxes. (You're still protected by flatpak's primary sandbox, but browser tabs will no longer be subsandboxed separately from each other.)
from org.gnome.epiphany.
It's a webkit issue, you want to downgrade the runtime as well. Try flatpak update org.gnome.Platform//3.38 --commit=edcf9927abf4b19e354070b62e2825b3ce13158f4a51b6010f8b56e62a1c26be
(in conjunction with ephy 3.38)
from org.gnome.epiphany.
Please post a backtrace for the web process crash (flatpak-coredumpctl org.gnome.Epiphany
).
Since elementary does not have coredumpctl working by default, you'll have to research how to get that working.
from org.gnome.epiphany.
Isn't this a problem for you right now? Then it must be something with the elementary devs should solve. This makes this issue unfunctional. Closing it then.
BTW I couldn't get to have an output, i've installed debug package for org.gnome.Epiphany too but it gives this:
Traceback (most recent call last): File "flatpak-coredumpctl", line 83, in <module> coredumper.run() File "flatpak-coredumpctl", line 44, in run subprocess.check_call(["coredumpctl", "dump"] + shlex.split(self.coredumpctl_matches), File "/usr/lib/python3.8/subprocess.py", line 364, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['coredumpctl', 'dump']' returned non-zero exit status 1.
from org.gnome.epiphany.
Looks like I am getting the same crash on Fedora 34 (beta).

Well you're missing debuginfo. Can you please run flatpak install org.gnome.Epiphany.Debug org.gnome.Sdk.Debug//40
, then flatpak update
, then try again? That will show us which line of code is crashing. This time, use bt full
instead of plain bt
so I can see the stack variables.
from org.gnome.epiphany.
I think what's happening is the web process crashes immediately after it is launched. GSubprocess notices, g_subprocess_get_identifier() returns nullptr, and then the UI process crashes when passing that to g_ascii_strtoll(). The UI process should crash if the web process crashes on startup, but it should crash better, with an assert rather than a null pointer dereference.
To get a backtrace for the web process crash, look up the pid of the crashing web process using coredumpctl
-- it will probably be listed immediately before the UI process crash at the bottom of the coredumpctl output -- then run use flatpak-coredumpctl org.gnome.Epiphany -m PID
to get it in gdb.

Well, I installed all the packages now and now get this:
flatpak-coredumpctl org.gnome.Epiphany

There's a gdb process causing 100% cpu load on one core but there doesn't seem to be a crash now. coredumpctl does not show any dumps after 10:29:07 CEST this morning when I posted the above output.
Also, there is no window popping up when run in flatpak-coredumpctl. I window is drawn however when run normally. No web rendering but menus etc seem to be working fine.

Patience! :) Either it will print a backtrace, or you can report a bug against gdb if not. But it will probably print a backtrace. It just takes a while because the debuginfo is huge.
Also, there is no window popping up when run in flatpak-coredumpctl. I window is drawn however when run normally. No web rendering but menus etc seem to be working fine.
Perhaps you mistyped here? You cannot use flatpak-coredumpctl to do anything other than open a core dump in gdb.
from org.gnome.epiphany.
After letting it run for about 10 minutes I got another entry in coredumpctl:
...

How would I tell if this is a web or UI process?

No idea if this is helpful:

How would I tell if this is a web or UI process?
epiphany is the UI process. The web process is WebKitWebProcess.
No idea if this is helpful:
That's a great backtrace for the UI process crash, which confirms my previous theory and is enough to fix the UI process crash. I will fix that now.
As for the web process side of this... if you really don't see WebKitWebProcess crashing in coredumpctl, then that's real bad luck. Check your journal and look for anything at all suspicious. Maybe it's being killed by systemd-oomd or something weird like that?

Well it looks like nothing is happening to the web process at all, but that seems unlikely. Let me install this and see if I can reproduce....
from org.gnome.epiphany.
So here's what I have, I get a "Locale not supported" warning first and then the process crashes.

If I add a random env var with an emoji afterwards it crashes again

The Spanish locale is broken in the sandbox for unknown reasons. But not when using flatpak-spawn:
[📦 org.gnome.Epiphany.Devel ~]$ LANG=es_ES.utf8 flatpak-spawn locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
because flatpak-spawn runs the process with the host environment. But after https://trac.webkit.org/changeset/272179/webkit, we now manually forward the entire environment to flatpak-spawn. So WebKit will now do something like this:
[📦 org.gnome.Epiphany.Devel ~]$ flatpak-spawn --env=LANG=es_ES.utf8 locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory

LC_ADDRESS="es_ES.utf8"
LC_TELEPHONE="es_ES.utf8"
LC_MEASUREMENT="es_ES.utf8"
LC_IDENTIFICATION="es_ES.utf8"
LC_ALL=
When the locale is broken, we fall back to C locale, and then UTF-8 characters like
[📦 org.gnome.Epiphany.Devel ~]$ flatpak-spawn --env=FOO=\360\237\223\246 locale
flatpak-spawn: Invalid byte sequence in conversion input
Try "flatpak-spawn --help" for more information.
OK, so now we have a minimal reproducer that doesn't involve WebKit or Epiphany at all. I'm guessing that locales are somehow generally broken in the runtime? @alatiera is it time to move this issue to gnome-build-meta?
from org.gnome.epiphany.
Checking Epiphany's Add Language dialog, I see only three locales exist within the runtime: English (Canada), English (United Kingdom), and "System languages (en-US, en)" which is English (US).
In contrast, Fedora's Epiphany presents me with several dozens of choices for locale. Selecting one of these locales using the LANG environment variable is not actually going to work, because translations are not going to be installed unless I install the relevant Fedora language pack, but at least it doesn't break and fall back to the C locale.
I don't know how runtime locale extensions work, but it sure seems like the selected locale likely does not exist at all within the runtime.
from org.gnome.epiphany.
flatpak config
might be instructive
from org.gnome.epiphany.
In my case I have:
$ flatpak config
languages: *unset* (default: en)
extra-languages: *unset*
After changing my formats to German using the Region & Language panel, Epiphany starts crashing. flatpak config seems to notice immediately:
$ flatpak config
languages: *unset* (default: de;en)
extra-languages: *unset*
I guess the problem is use of German formats with English locale. But again, this is not an Epiphany or WebKit bug because flatpak-spawn itself is broken. IMO it is reasonable for WebKit to crash if flatpak-spawn is not working.
@veyselerden please run locale
and post the output here, I'm curious to see whether you also have a mixed locale.
from org.gnome.epiphany.
BTW I will fix the UI process crash in https://bugs.webkit.org/show_bug.cgi?id=224209, but that is not the main problem here.
from org.gnome.epiphany.
So this is a case of flatpak not working correctly by default with mixed locales. For some reason, flatpak doesn't seem to download all the locales by default (See flatpak/flatpak#3514 flatpak/flatpak#3563 flatpak/flatpak#3712).
What you can do is to set the correct languages in flatpak config
(if necessary, it may have been fixed at some point) then run flatpak update
(or maybe flatpak uninstall org.gnome.Platform.Locale//40
then flatpak update
). You can check flatpak info org.gnome.Platform.Locale//40
for installed subdirectories, which should contain all the locales you're using.
Of course, what I'm describing above is a workaround, and flatpak should do the right thing by default.
from org.gnome.epiphany.
Thanks Abderrahim.
Since there are no changes to make in Epiphany, I'm going to close this in favor of any of flatpak/flatpak#3514 flatpak/flatpak#3563 flatpak/flatpak#3712, which are all duplicates of each other. Once those are fixed, Epiphany will stop crashing. In the meantime, workaround is to manually disable the sandbox or not use mixed locales.
from org.gnome.epiphany.
Let's continue in flatpak/flatpak#3712.
from org.gnome.epiphany.
FYI: I downgraded Ephy to previous version (3.38) with:
flatpak update --commit=2f7bd4f9731f4d665e5194206fbc451e501f6554ab7285a85880ce21874e2ec3 org.gnome.Epiphany
... and the issue doesn't go away. This is probably because webkit
is the same and this issue is therefore not related to Ephy per se, but rather webkit & flatpak conflict, as pointed out by @mcatanzaro. Just wanted to log this here.
from org.gnome.epiphany.
Downgrading the runtime won't work, we update webkit in older ones too, cause security and all.
from org.gnome.epiphany.
It will, that's the last commit before webkit 2.32.0.
from org.gnome.epiphany.
You'll have to pin to that runtime version forever until someone has time to fix the flatpak bug. Sorry. :/
from org.gnome.epiphany.
You'll have to pin to that runtime version forever until someone has time to fix the flatpak bug.
I figured, I will wait for the fix. Just wanted to log the info that this is really unrelated to Ephy v40 and can be reproduced even in previous versions, if the runtime (and its webkit) has been already updated..
from org.gnome.epiphany.
i have this issue only after updating Platform while Web is running. restarting Web fixes it
my locale is not mixed:
