Hat Jemand eine Idee, woran das liegen könnte?

TheChief · 14. Februar 2015

Dürfte an scraper2vdr liegen. Zumindest ist das bei mir so. mini73 hatte irgendwo einen Patch dazu gebastelt, bin aber noch nicht zum Testen gekommen.

3PO · 14. Februar 2015

Hmm.......,

aber wie schon gesagt, einzeln funktioniert die Abfrage:

Code

vdr01_64 ~ # vdr -V -P scraper2vdr
vdr (2.1.10/2.1.10) - The Video Disk Recorder
scraper2vdr (0.1.6) - 'scraper2vdr' plugin
vdr01_64 ~ #

TheChief · 14. Februar 2015

Bei mir nicht

Code

root@homeserver:/var/cache# vdr -V -P scraper2vdr
vdr (2.1.10/2.1.10) - The Video Disk Recorder
scraper2vdr (0.1.6) - 'scraper2vdr' plugin
Speicherzugriffsfehler

Aber wie gesagt, hab minis Fix nicht drin. Kann auch ein anderes Plugin sein, was irgendwas nicht korrekt initialisiert.

kls · 14. Februar 2015

Es könnte ja sein, daß scraper2vdr etwas überschreibt, das beim nächsten Plugin dann zum Absturz führt, aber wenn scraper2vdr allein ausgeführt wird kein Problem macht.

Zitat von TheChief

[...] Aber wie gesagt, hab minis Fix nicht drin. ...

Ich auch nicht, ich habe die unveränderte Version aus dem git.

TheChief · 14. Februar 2015

Kannst ja mal das probieren.

Ich lass es bei mir auch eben mal durchlaufen und schaue, ob der Speicherzugriffsfehler dann weg ist.

Mit dem o.g. Patch, lässt sich scraper2vdr bei mir nicht mehr bauen:

Bekomme aber immernoch einen segfault, weiss aber nicht, ob das vom scraper kommt:

Code

Denke aber schon, denn vdr -V -P scraper2vdr gibt auch einen segfault.

3PO · 14. Februar 2015

Mit Deiner Version, endet "vdr -V" mit:

Code

*** Error in `vdr': corrupted double-linked list: 0x0000000000884f40 ***

TheChief · 14. Februar 2015

Ich bekomme mit beiden Abfragen den gleichen segfault. Kanns aber mangels C-Programmierkenntnissen auch nicht wirklich fixen.

mini73 · 14. Februar 2015

Ja, mein Patch war doof, die Zuweisung muss man auf zwei Zeilen aufteilen.

Ich hab irgendwie ein Dejavu. Baut scraper2vdr evtl. schon eine Verbindung zur DB auf bzw. Bei der Versionsabfrage nicht, versucht aber anschließend, sie zu schließen? Hab heute leider keine Zeit zum Testen.

Ansonsten ruhig horchi oder louis mal anticken.

Lars

TheChief · 14. Februar 2015

Ja, so etwas vermute ich auch. Bei epg2vdr sieht der Code aber ganz ähnlich aus, nur die libhorchi unterscheidet sich grössenmässig. Vielleicht gibts da Unterschiede.
