Segfault VDR 1.6.0-1 mit FFnetdev/statusleds Plugins

dad401 · May 4, 2008 at 12:26 PM

Hallo,

nachdem ich für den VDR 1.6.0-1 (inkl. Extension-Patch59) ein aktuelles Debian Etch aufgesetzt habe, lief beim Kompilieren des VDR soweit alles glatt. Allerdings hatte ich beim Beenden des VDR´s immer merkwürdige Speicherzugriffsfehler (Segmentation Faults) und beim Testen "*** glibc detected...".
Nach ewiger Testerei, VDR 1.6.0-1 ohne Extensionspatch etc. hab ich endlich (hoffentlich alle) Übeltäter identifizieren können. Dabei liegt es nur an den Plugins, nicht am VDR (mit/ohne Patches).

Als Anhang liefere ich hier mal die Backtraces zu allen 2 Plugins - evtl. hilft es einem ja weiter.

Da ich ungern auf diese Plugins verzichte, wäre es schon schön, wenn diese wieder richtig funktionieren würden...

Gibt es da evtl. schon inoffizielle Updates?

Danke & Gruss
Marcus

Update: Plugin Fritzbox entfernt - es gab einen Segfault mit V0.0.10 - scheint aber in 1.0.0 behoben

Hallo,

ich habs mal gewagt und das statusLEDs 0.3 so verändert, dass das Stoppen jetzt fehlerfrei funktionieren sollte (zumindest crasht es jetzt bei mir nicht mehr, auch wenn ich nicht alles ausprobieren konnte). Nebenbei habe ich auch gleich noch den gettext-Support eingebaut, damit im VDR 1.6 auch wieder deutsche Texte erscheinen.

FireFly
PS: und nein, ffnetdev schaue ich mir nicht an. Das ist mir zu komplex und ich kann es nicht testen.

Super - besten Dank! Werde es gleich mal testen...

Dann kann ich mir ein "aptitude install blinkd" sparen

Evtl. wird ja ffnetdev irgendwann vom Entwickler? angepasst. Falls ich´s zur Not doch mal brauche, muss man eben erstmal mit dem Segfault beim Beenden leben...

Gruss
Marcus

Hallo,

in der SVN-Revision 32 sollten bei ffnetdev keine Segfaults mehr kommen. Welchen Stand nutzt ihr?
