mythfrontend DoHandleUndelete - loops in Master

[jksjdevelop@…]

v0.28-pre-3078-g7126654 Attempting to restore a deleted program using mythfrontend causes the back end to loop. The restore operation is however successful and the program can be viewed having restarted the backend. Strangely the same operation works perfectly from mythweb.

AFAIK recording was not undeleted manually.

Tried to remove the recording rule from recording rule list via mythweb, did not help. Delete processing for the named recording "An der Seite" was not processed by backend.

let me know, if you need anything else.

Replying to matthias.strubel@…:

AFAIK recording was not undeleted manually.

Not true, just talked with my wife: The recording was deleted and undeleted (within a few seconds) via mythfronend.

I had 24hours a loop until the filesystem was full of logfiles (mysql bin-logs).

I resolved the problem with: removing the recording rule (did not help in first place) and then removed the corresponding entry in the table recordedprogram .. ( I hope that does not cause further issues)

Richard,

Does this need a cherry-pick back to 0.28 or is that unaffected?

Regards Stuart

[Peter Bennett]

FYI I also experienced this problem a few weeks ago in 0.28. Killing the frontend resolved it, but only after I had tried a lot of other things that did not work. I vote to cherry-pick into 0.28.

[peper03]

Yes, it should be in 0.28 too. I don't actually think there's any risk to cherry-picking it immediately since the effects are fairly clear.
