» Dear Lazyweb: How can I fix this deadlock on shutdown
Thu, 09/30/2010 - 17:14
Hello dear lazyweb,
I have a problem that I could not solve nor find help by my usual paths. I’m speaking about a deadlock on shutdown I get sometimes with what will become KDevelop 4.1. You can find a backtrace in this bug report:
https://bugs.kde.org/show_bug.cgi?id=239032
The thing is this: Apparently some global QMutex is getting destroyed by the exit handler but the call to __pthread_cond_destroy does not return.
I have no clue on how to fix this. Is there at least a way to find out which mutex this is? Someone told me to have a look in /proc/PID/maps but there I only found out that - what a suprise - ~QMutex is defined in libQtCore.so… Or should I have looked for the this=0xfffffe00 address? Speaking of which - isn’t that address messed up?
Does anyone have a better idea?

Hey there :)
As I announced on the kde-core-devel mailing list, I planned to improve Dr Konqi for a long time, as for me as a developer it is an invaluable tool. Well, yesterday I sat down and implemented the first two things which I wanted for a long time:
Scroll to KCrash
Once the backtrace got loaded, Dr Konqi will automatically scroll to the line that contains [KCrash Handler]. No need to find that manually anymore. Awesome :)
Colors!
Yeah, you should know that I as a KDevelop user and developer am addicted to syntax highlighting. That’s what I did for Dr Konqi as well now:
So anyone using KDEBase trunk will now have a shiny Dr Konqi :) Feedback appreciated, esp. whether more or less should be highlighted. I personally found it overly colorful when I also highlighted pointer adresses (ignore the bug in that outdated screenshot). What do you think?
Anyhow, thanks to George Kiagiadakis for helping me find my way through Dr Konqi sources and accepting my feature additions.
Update
I put some more feedback into reality: Fixed width font, null pointers are bold and in addition common functions that lead to exits are now highlighted in red (i.e. qFatal, __assert_fail and abort):
