Crash on Bitbucket.com

[Dickby]

Hi,
I use this browser on arch-linux 86_64.
It crashes every time I open a site of bitbucket.com.
I tested this on two laptops. I hope it can be fixed.
I really love this browser, Thanks.

I couldn't reproduce this issue on https://bitbucket.org/ . Which URL crashs the browser (exactly) ?

Also, could you provide a stacktrace via gdb ? in order to help us to locate the problem ?

[Dickby]

It happens at every bitbucket site, for example https://bitbucket.org/emacsway , it just loads to 89% and freezes.
how should I do that stacktrace, are there any debug flags for vimb or do i have to recompile with -g flag?
I compiled vimb with gtk3 support, could that be the reason?

[semarie]

I use gtk2. So It may be the reason (but normally vimb works well with gtk3 too). I couldn't check with gtk3 now, but I will try soon.

For the stacktrace, just adding -g to CFLAGS in config.mk should be enough (and recompile). If you aren't familiar with gdb, I could provide a step-by-step procedure.

You could also try to disable plugins (set plugins=false) and/or javascript (set scripts=false) before opening the page, in order to check if the crash if related to one of them.

I've never heard of a crash there - but hanging on bitbucket pages is a WebKit1GTK bug which is present in all browsers using that (e.g. dwb or luakit too).

[Dickby]

With set scripts=false it works fine.
Is that enough information?
If you still need a stacktrace for tracking down the bug, let me know.

[semarie]

a stacktrace would permit to locate the bug (I hope).
Knowing that with set scripts=false it don't crash just permit to known the bug should be related to javascript.

I can't reproduce this issue. I use arch-linux 86_64 too, vimb does not crash neighter with GTK2 nor with GTK3. But with enabled JavaScript this hangs the browser on hight cpu usage.

Just a "me too" here. I'm pretty sure it's bad javascript on the site.

[shioyama]

Crashes for me too -- actually doesn't crash but freezes up and swallos 100% of cpu, which is pretty bad...

[fanglingsu]

@shioyama The hang on bitbucket is a knwon webkit issue and affects all Webkit browsers like mention by The-Compiler.

[fanglingsu]

According to the hang on bitbucket, and some other sites. It's possible to disable the JavaScript JIT Compiler in Webkit by setting environment variable JavaScriptCoreUseJIT to 0. When I start vimb by JavaScriptCoreUseJIT=0 vimb bitbucket is fast also with enabled javascript. Maybe this helps also against the reported crash, but I can't say, because it never crashed on my systems.

[TieDyedDevil]

This is interesting. For some reason, vimb no longer crashes on
bitbucket.com. It used to, and also on other Atlassian sites. I've had to
use icecat, a Firefox derivative) to access those sites.

I'm currently compiling vimb against webkitgtk (GTK2, not 3) version 2.4.9.

[fanglingsu]

Is there some one else where vimb still crashes on bitbucket?

[Dickby]

It still crashes on my Computer.

[fanglingsu]

@Dickby Does vim also crash if you run it like this JavaScriptCoreUseJIT=0 vimb https://bitbucket.org/?

[Dickby]

@fanglingsu It doesn't crash!!
Is there an option for my vimb config file that sets this as default?

[fanglingsu]

@Dickby This is a normal environment variable that is used by webkit. So you can set/export it from your shell configuration for example /etc/profile, ~/.bashrc, ~/.zshrc or ~/.zshenv.
