Unable to shutdown VDR successfully (Backtrace attached)

[CReimer]

Hi manio,

Because oscam.to is no longer available, I try it here

I always get a Backtrace when I shut down VDR while I watch a crypted channel (e.g Prosieben HD)

http://pastebin.com/Jy4QATrF

After sending the SIGTERM softhddevice's output starts to stutter, and after a timeout of 20 seconds, VDR receives the SIGKILL by my runvdr script, and exits with exitstatus 1.

Greetings

So if you have an FTA channel and stops vdr, than it is ok?

[CReimer]

Yes, exactly

[manio]

Probably the bug is also reproducible in my environment. I'll try to figure it out...

[manio]

I was wrong - i cannot reproduce it localy :( I was trying to shutdown vdr multiple times while channel is decrypting and always got proper exit without segfault. Can you try it with minimal plugins loaded? Please also attach more detailed log this way: run vdr under gdb, eg: gdb --args vdr -Pxvdr -Pdvbapi then type: set solib-search-path /usr/src/vdr/PLUGINS/lib of course set this path to your plugins path then type "r" to run under gdb when error occur please type: bt full and send me this info

Here they are. But I can't see anything interesting in there. I can reproduce this very well,

first SIGTERM: sofhddevice's output starts to stutter second SIGTERM: vdr exits

[manio]

Please try this patch: http://skyboo.net/dvbapi.diff and let me know if it helps

[CReimer]

No the problem is still there.

Here is a log of the last few seconds before VDR gets forced to exit.

Ok, next test: schedule a recording on a crypted channel, then exit vdr run it with: vdr -Pdvbapi (and that's all) after eg a minute or two try to SIGTERM see if it exits cleanly and a recording is ok

[CReimer]

Even if there's only dvbapi, it hangs.

Hi Thank you for the log. Can you do the same recording test but on vdr-sc plugin? dvbapi plugin shares same DeCSA TS buffer code so I assume same problem is there. Can you confirm it?

[CReimer]

I tried it several times, with only sc activated. Unfortunately everything works with sc.

[manio]

How about this new patch: http://skyboo.net/dvbapi.diff Please also set plugin debug level to 3 when sending me the log.

[CReimer]

OK, with that patch it seems to be fixed.

[manio]

Great. Can you tell me which of those two lines makes a good effect?

[CReimer]

The first line. "Cancel (3)" seems to be useless.

[manio]

Ok, thank you for your help and time spent on this, I'll commit a fix...
