» Valgrind Highlighting on BKO

Thu, 07/04/2013 - 19:30

Hey all,

you didn’t hear anything from me since quite some time… Thing is, this is my last “regular” semester of university where I have two lab courses that are very time demanding. The year after, I’ll be spending time on my master thesis, which hopefully will allow for some more leisure time for KDE.

Anyhow, a small project which I just worked on to write some small lines of code again was to make my BKO backtrace highlighter work on Chromium. It requires the Tampermonkey extension to get more compatibility with Greasemonkey of Firefox fame, otherwise it works more or less out of the box!

After fixing some small other inconsistencies I can now say that it works fine in both, Firefox and Chromium! I furthermore took the liberty to extend its functionality a bit: You now also get highlighted Valgrind traces, i.e. generated by memcheck and other error reporting tools - yay!

Oh and before I forget it: See you all next week at Akademy! I’m so looking forward for the intense hacking and socializing, esp. since I missed last year! And: If you are interested in how to improve the performance of your application(s), make sure to attend my talk on Sunday: Apps On Speed

» More BKO javascript goodness

Sat, 09/25/2010 - 22:54

Hey all,

I’ve improved my javascript highlighter for backtraces on bugs.kde.org and fixed some bugs (e.g. the BUG 123456 links where lost before). Additionally I just added another feature that gives you a nice little navigation bar like this:

Pressing crash scrolls the window to the [KCrash Handler] in that backtrace, prev thread and next thread do what you would think they do.

To get all the goodies, click this link to install the updated script in GreaseMonkey:


NOTE: This also works with Tampermonkey in Chromium!

Happy backtrace reading!

PS: Yeah, we really should get this by default into BKO… I’ll write a mail to the sysadmins now.

» Highlighted Backtraces on BKO

Mon, 09/20/2010 - 19:05

Hello everyone, the “I can syntax highlight everything” guy speaking again :)

Yeah, I couldn’t sleep well after I put colors on Dr Konqi. I also did the same for Kate, if you did not notice it. There is a new GDB Backtrace syntax highlighting file for it, giving you the same pleasant experience you are now used to from Dr Konqi. Awesome.

But well, lets admit it: What use are these two for bug triaging? Visit any crash report on bko and you are left to plain old black-on-white… Stone-age stuff, lets put it on LSD, shall we not? I propose: The GDB Backtrace highlighter GreaseMonkey userscript!

Bug reports, feedback, pizza & beer all welcome :)

PS: How is GreaseMonkey for Konqueror coming along, anyone working on that? Does someone know whether Chrome or Opera could be made to work with this?

PPS: We could also install this script directly on BKO, but I fear it might be a tad bit slow, esp. for huge backtraces.

PPPS: Attached backtraces should be setup to be opened in Kate :)
