Hi,
we*) notice a seqfault of cutting Thread on "Low disk space!", if OSD used during cutting process.
i think, reason is a call of a OSD function from background cutting thread.
I tested only on 1.3.32, but 1.3.37 should also affected
(gdb) thread 5 [Switching to thread 5 (process 4733)]#0 0xb7e68114 in ioctl () from /lib/tls/libc.so.6 (gdb) bt #0 0xb7e68114 in ioctl () from /lib/tls/libc.so.6 #1 0x080aa202 in cDvbOsd::Cmd (this=0x8c9e710, cmd=OSD_Clear, color=0, x0=0, y0=0, x1=0, y1=0, data=0x0) at dvbosd.c:110 #2 0x080a9c13 in cDvbOsd (this=0x8c9e710, Left=54, Top=504, OsdDev=5) at dvbosd.c:63 #3 0x080aa816 in cDvbOsdProvider::CreateOsd (this=0x8c81930, Left=54, Top=504) at dvbosd.c:183 #4 0x080e4854 in cOsdProvider::NewOsd (Left=54, Top=504) at osd.c:738 #5 0x08110911 in cSkinSTTNGDisplayMessage (this=0x8c95570) at skinsttng.c:1052 #6 0x08111100 in cSkinSTTNG::DisplayMessage (this=0x8c819f0) at skinsttng.c:1117 #7 0x0810509e in cSkins::Message (this=0x81f73e4, Type=mtWarning, s=0x8143f3f "Platte beinahe voll!", Seconds=30) at skins.c:179 #8 0x080bb3d4 in cInterface::Confirm (this=0x8c818c0, s=0x8143f3f "Platte beinahe voll!", Seconds=30, WaitForTimeout=false) at interface.c:71 #9 0x080ece45 in AssertFreeDiskSpace (Priority=-1) at recording.c:147 #10 0x0809d62f in cCuttingThread::Action (this=0x8c92528) at cutter.c:86 #11 0x0811b716 in cThread::StartThread (Thread=0x8c92528) at thread.c:234 #12 0xb7fb8b63 in start_thread () from /lib/tls/libpthread.so.0 #13 0xb7e6f18a in clone () from /lib/tls/libc.so.6
Here a possibly solution :
--- recording.c.org 2005-09-11 17:52:31.000000000 +0200 +++ recording.c 2005-12-07 21:33:18.000000000 +0100 @@ -144,7 +144,7 @@ } // Unable to free disk space, but there's nothing we can do about that... isyslog("...no old recording found, giving up"); - Interface->Confirm(tr("Low disk space!"), 30); + Skins.QueueMessage(mtWarning, tr("Low disk space!"), 30); } LastFreeDiskCheck = time(NULL); }
*) I'm not the original bug reporter, but i could this seqfault reproduce http://www.vdr-portal.de/board/thread.php?threadid=42375&sid=
