I noticed that the web process crashes immediately when visiting youtube.com. I want to report a bug. Since I built webkit using update-webkitgtk-flatpak and then build-webkit, I can't use the normal system coredumpctl to get a backtrace: I have to go through webkit-flatpak. I try this:
$ webkit-flatpak --gtk -m 19974 --gdb
where 19974 is the pid of the crashing web process.
It (unexpectedly?) fetches a bunch of git repos, then opens up gdb:
Core was generated by `/home/mcatanzaro/Projects/WebKit/WebKitBuild/Debug/bin/WebKitWebProcess 5 37'.
Program terminated with signal SIGSEGV, Segmentation fault.

It's really great that we have the --gdb and -m functionality built-in, but there's no debuginfo so I don't understand how to use it.

Just found this in org.webkit.WebKit.yaml:
build-options:
cflags: -O2 -g
cxxflags: -O2 -g
strip: false
no-debuginfo: true
I don't know why we're using no-debuginfo: true, but that seems pretty unfriendly for a runtime that's exclusively intended as a developer tool. Thibault, can we change that, or is there an important reason for it?
Michael Catanzaro
I guess that controls what we build ourselves though, not the runtime. We need org.gnome.Sdk.Debug to be installed.
Michael Catanzaro
I'm running 'update-webkitgtk-flatpak' right now and it is installing debuginfo. Perhaps I hadn't set debug configuration last time I ran it? Not sure. We'll see what happens....

Right, Sdk.Debug is installed only when `--debug` is passed.

Seems like all is solved now? I'll assume so and close. Please reopen if needed!
