qupzilla hangs and CPU usage goes up to 100% when preventing notification from showing. #2190

Closed lonicerae closed 7 years ago

lonicerae commented 7 years ago

Hello,

I'm using self-compiled qupzilla whose source is provided from Debian:

$ dpkg -l | grep qup
ii  libqupzilla-dev                                             1.8.9~dfsg1-3.1                      amd64        development files for qupzilla's shared library
ii  libqupzilla1                                                1.8.9~dfsg1-3.1                      amd64        shared library and header files for qupzilla
ii  qupzilla                                                    1.8.9~dfsg1-3.1                      amd64        lightweight web browser based on libqtwebkit

In fact, I've tried official released qupzilla 1.6.6 and 1.8.9 by Debian, but all of them are hitting this issue.

This issue can be reproduced 100% on salesforce website by clicking on the 'Deny' button when the notification "Allow na7.salesforce.com to show desktop notifications" prompts on this webpage:

https://na7.salesforce.com/home/home.jsp

For details, please refer to the attachment.

When qupzilla hangs, the CPU usage can go up to 100%. Getting the PID of the running qupzilla:

$ ps aux | grep qu
test     5769 39.9  4.0 4951336 307940 pts/2  Rl+  20:57   0:33 qupzilla
test     5843  0.0  0.0  14404  2256 pts/0    S+   20:58   0:00 grep qu

And use gdb -p 5769 to look into qupzilla:

I use gcore to grab a coredump file for qupzilla, but it's really a big file about 2.4GB. Just let me know if you would like this coredump file and I'll find a way to transfer it to you.

BTW, I'm sorry that I'm not able to build the latest qupzilla on my Debian Jessie 8 due to lacking the latest QT5..

Thank you!

Best Regards, Flos

ghost commented 7 years ago

Good paint job :smile: I'm afraid since 4 Nov 2016 the support of QupZilla QtWebKit has been deprecated. BTW, you can try the latest precompiled QupZilla. In the next release, it will be officially available in this format.

lonicerae commented 7 years ago

Hahaha! Yep, purely hand-made. :smile:

Ah~Okay, I will grab the latest bundle and test it again.

nowrep commented 7 years ago

Pretty much what @cranes-bill wrote.

Your QupZilla version is old and no longer maintained. Also it looks like bug in QtWebKit instead, which is also unmaintained for a long time already.

lonicerae commented 7 years ago

Agree. Thanks @nowrep.
