Re: [Bug 657803] Re: Weather Applet and High CPU Usage

 

Hi,
what would be very helpful is to launch the dock with ddd and reproduce the
bug, ddd will then stop the program where it crashed and hopefully gives an
useful backtrace.
I don't think the recent changes in the applet are involved here (it was
about double-click on the icons)
it may be a problem in libcurl or in libxml, failing to get data or getting
wrong xml data, hard to say (and hard to reproduce).
Thanks in advance !

Bug description:
This bug is somehow odd but I try to explain it as clearly as possible. I use my whole band-width for some download, for example, when downloading heavy files with Synaptic. Then I intentionally middle click on the weather applet to see what happens. Of course, it can't get any information and its icon changes because my whole band-width is used by Synaptic or another heavy download process. But, after a few seconds, something bad happens: one of my CPU cores goes to 100%. I can't quit Cairo-Dock normally but can kill its process and then, CPU usage gets normal again.

When I don't middle click on the weather applet, sometimes the same thing happens and sometimes Cairo-Dock crashes and automatically restarts.

In the case of 100% CPU usage, I see no message in xsession-errors except normal messages related to the weather and mail applets, which say that they cannot retrieve information. In the case of crash and restart, I don't clearly remember the messages but I think they said that the culprit might be the weather applet.

I see this problem only after the recent changes in the weather applet of the bazaar releases (5th Oct). However, I'm not sure that it's the main cause.
