[asterisk-dev] app_voicemail generates locking errors since 1.2.10

[Kai Militzer]

Hello everyone,

I just upgraded my 1.2.9.1 to 1.2.10, checked the voicemail for a user 
and suddenly got the following errors:

Jul 19 08:53:23 x.x.com asterisk[17525]: ERROR[17525]: app.c:1161 in 
ast_lock_path: Unable to create lock file 
'/var/spool/asterisk/voicemail/default/02418903110/Old': No such file or 
directory
Jul 19 08:53:23 x.x.com asterisk[17525]: ERROR[17525]: app.c:1196 in 
ast_unlock_path: Could not unlock path 
'/var/spool/asterisk/voicemail/default/02418903110/Old': No such file or 
directory

I first thought something got messed up and deleted the whole directory 
for the extension (which didn't contain voicemail messages anyway), but 
then got the locking error already for INBOX.

So I checked the Changelog and came across that entry:

         * app.c: fix a case where ast_lock_path() could leave a
           randomly-named lock file hanging around make ast_unlock_path
           actually report when unlocking fails

and that one

         * app.c: GRRR no fprintf!

I then looked in app.c and found out, that the "Unable to create lock 
file" was not an ast_log but an fprintf in 1.2.9.1 and so simply got not 
  printed in the error log.

The "Could not unlock path" was newly added. Before 1.2.10, the 
situation was the same, i.e. the error happend, but simply was not 
locked. As I am not really a programmer, I was not able to find a 
solution to this. I guess the locking in voicemail is kind of 
inaccurate, it simply tries to lock all possible subdirectorys, even if 
they do not exist.

I didn't file a bug report, as I have no patch.

Regards,
Kai
