Bug 195908 – app-admin/gkrellm-2.3.0 Segmentation fault when x11-plugins/gkrellm-radio-2.0.4 installed

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description DEMAINE Benoît-Pierre, aka DoubleHP 2007-10-15 03:18:57 UTC]

I was having a bug (segfault; I re-emerged all ebuilds listed by something like
emerge -ep world |grep krellm

emerge -va1  app-admin/gkrellm x11-themes/gkrellm-themes x11-plugins/gkrellm-reminder x11-plugins/gkrellm-radio  x11-plugins/gkrellm-xkb x11-plugins/gkrellmwireless x11-plugins/gkrellmlaunch x11-plugins/gkrelltop x11-plugins/gkrellm-gamma x11-plugins/gkrellm-countdown x11-plugins/gkrellm-hddtemp x11-plugins/gkrellm-leds  x11-plugins/gkrellm-volume x11-plugins/gkrellmss x11-plugins/gkrellmms

and bug persists:

I have been using this skin for years (at least 2 or 3).

More logs coming.

Hope this is helpfull.

hmmm, maybe it's again that /dev/radio bug I met on debian 4 years ago ...

or gettimeofday() call ? I am having "time problems" with mplayer since my last update 12h ago: movies are played about 8% too fast; maybe something wrong in the RTC driver ? Linux API ? ...

[Comment 3 DEMAINE Benoît-Pierre, aka DoubleHP 2007-10-15 03:32:10 UTC]

emerge -C x11-plugins/gkrellm-radio
fixed it.

Changing topic from
> app-admin/gkrellm-2.3.0 Segmentation fault

to
> app-admin/gkrellm-2.3.0 Segmentation fault when x11-plugins/gkrellm-radio-2.0.4 installed

Thus removing bug 195522 block.

I tried to reproduce again:
remerge => rebug
remove => solved
and so on ...

[Comment 4 Jim Ramsay (lack) (RETIRED) 2007-10-16 11:50:38 UTC]

Indeed, there is a bug - If /dev/radio doesn't exist, this plugin blows up.

I may devise a simple "Don't segfault, just die slightly more sane" patch.

[Comment 5 Jim Ramsay (lack) (RETIRED) 2007-10-16 11:51:47 UTC]

In the mean time I have removed it from the meta "gkrellm-plugins" package, just in case.  Hopefully you would only install this if you have a radio tuner card anyway, and would therefore have this device node present...

[Comment 6 DEMAINE Benoît-Pierre, aka DoubleHP 2008-12-08 15:02:55 UTC]

Still happens with app-admin/gkrellm-2.3.1

(In reply to comment #6)
> Still happens with app-admin/gkrellm-2.3.1
 
Yes, it's definitely due to a bug in the x11-plugins/gkrellm-radio plugin which has very little to do with gkrellm itself.  I'm sure every version of gkrellm will segfault in the same way if you try to initialize the gkrellm-radio plugin without a /dev/radio device present.  I just haven't had a chance to patch the plugin itself.

If you do, please post the patch here and I'll incorporate it into the gkrellm-radio plugin.

[Comment 8 Jim Ramsay (lack) (RETIRED) 2010-07-27 17:28:41 UTC]

Odd: I can't seem to reproduce with gkrellm-2.3.4.  Would you mind retesting with latest?

[Comment 9 DEMAINE Benoît-Pierre, aka DoubleHP 2010-07-27 19:02:30 UTC]

I will try, IIRC, the bug may depend on how devfs/udev creates the nodes ...

Some particular udev conf will create what the original author had on his box; but udev variations maye create node with "wrong" names; IIRC, /dev/radio vs /dev/radio0 ... so, a simple mv from one to an other may help repro.

May need weeks before I have time to bother about this in details.

[Comment 10 Jim Ramsay (lack) (RETIRED) 2010-07-28 14:48:19 UTC]

I am unable to reproduce this bug with gkrellm-2.3.4 on a system that has no /dev/radio present at all, this was probably fixed by some of the stability enhancements between gkrellm-2.3.0 and -2.3.4.
