ring buffer overflows -> cDevice::Detach() blockiert...

jrie · May 26th 2016

Start() und Cancel() müssen auch aus dem mutexReceiver-block raus, das war der Grund für die blackscreens.
Anbei der hoffentlich finale Patch.
Bitte überprüfen, ausgiebig testen und rückmelden.

Guido17 · May 27th 2016

@jire, kann zwar nicht testen, aber langsam gefällt mir die Lösung. Der mutexReceiver-Block sollte nur das receivers Array schützen. Was ich nur in der Detach-Funktion betrachtet habe, hast du nun auch in der anderen Funktion umgesetzt, daher gefällt mir die Lösung.

Xcoder · May 27th 2016

@jire: auch der 4. Patch funktioniert problemlos.

Toller patch. Trotz extrem zapping kein hänger. Auch bei Aufnahme und OSD-Teletext.

Ich habe ein Paket für yavdr-testing [0.6] erstellt:

jrie · Jun 2nd 2016

Noch zur Erklärung:
Wenn Start() im mutexReceiver-Block ist, kann Folgendes passieren.
Attach() hat den mutexReceiver, Action() wartet auf den mutexReceiver, Start() wird in Attach() aufgerufen, Start() wartet darauf dass Action() fertig wird. Das führt zum THREAD_STOP_TIMEOUT in Start() und der neue Receiver Thread wird nicht gestartet => Black Screen.
Wenn jedoch der mutexReceiver vor Start() freigegeben wird, dann wird Action() fertig und der Thread rechtzeitig beendet und kann von Start() neu gestartet werden.

Diese Verschachtelungen sind ganz schön kompliziert.

Den deadlock gab es übrigens schon seit über 11 Jahren (seit mutexReceiver in vdr-1.3.18 eingeführt wurde).

Meiner Meinung nach kann der Patch so in die nächste VDR Version übernommen werden.
Dann kann man wieder sorglos Plugins wie osdteletext etc. benutzen.

fnu · Jun 2nd 2016

Wenn ich mir das so durchlese, ist doch inzwischen ein Thema für VDR Core, oder? Gibt es Einsprüche gegen eine Verschiebung des Threads?

[EDIT] Nach "VDR Core" verschoben.

===

Werde den Patch auch mal testen und dann berichten ...

Xcoder · Jun 2nd 2016

Für mich funktioniert der Patch perfekt. Auch mit Plugin-Vollaustattung gab es bisher keinen einzigen derartigen Hänger mehr. Vielen Dank an jrie.

Gruss, Xcoder

iNOB · Jun 3rd 2016

Kann auch nicht klagen. Weder Nebeneffekte noch Hänger feststellbar

tv-user · Jun 3rd 2016

Patched 2.1.6, so far no VDR crashes like I had before. Fast zapping with the motorola streamdev clients killed VDR, I've even build in a delay in my script to slow down zapping. But it looks like it is cured.

Thanx!!

hondansx · Jun 4th 2016

Kann ich bestätigen. Beim schnellen Zappen mit streamdevclients crasht die gepachte Serverseite (vdr 2.2).

jrie · Jun 4th 2016

Kannst du auch bestätigen, dass mein Patch (wie bei tv-user) hilft?
Denn darum geht es hier.

Oder wolltest du sagen, dass er bei dir NICHT hilft?

astra · Jun 8th 2016

Danke Jungs, bin zwar "nur" Anwender, aber dieses Ei stinkt mir schon seit langem!
Endlich läuft die Kiste beim zappen sauber durch, wenn diverse Aufnahmen laufen!
Vielen Dank :tup! !

rvdb · Jun 9th 2016

Running with this patch for a few days now, so far no problems.
Thanx

Super Patch. Macht vdr noch stabiler.

Mein vdr-2.2.0 läuft mit 3 usb dvb-c tunern und mit der 4er digibox satip. 24h7Tg.

Ergänzend fand ich kürzlich diesen thread.

https://www.linuxtv.org/pipermail/vdr/2016-May/029056.html.

Dieser Patch schaltet unbenutzte reciever idele um Energie zu sparen. Bei meinen 3 dvb-c
receivern sind dies ca. 6-8W. Der Power saving patch und dieser deadlock Patch hakeln ein wenig
beim patchen. ich habe das manuell nach meinen Gutdünken zusammen gebastelt. Aber vielleicht
sieht sich ein Profi dieses mal an.
Die Energieeinsparung durch bedarfsgerechtes aktivieren/dektivieren von Recievern
und das dann deadlockfrei, wäre ideal.

Gruß

fnu · Jun 9th 2016

jrie

Ich hatte eine bestimmte Situation wo es immer wieder zu dem Vorfall kam, den das Patch beheben soll. Am WE war es wieder soweit, was soll ich sagen, super, scheint gelöst und VDR ist stabil wie vorher auch bzw. nun noch etwas stabiler ...

Vielen Dank.

Ein Schnellschuss, probier den mal.
Da ist beim Detach() die camSlot Sache noch im mutexReceiver drin gelassen.
Auf die Schnelle sieht es mir so aus, als ob es da her kommen könnte.
Gerade keine Zeit tiefer zu gucken.

OK, danke. Patch ist drin. Da die Deadlocks nun wirklich sehr sporadisch auftreten, könnte es etwas dauern bis ich einen erwische, wenn es den nun überhaupt noch welche geben kann...

Gruss, Xcoder

ring buffer overflows -> cDevice::Detach() blockiert...
