[svn-commits] rmudgett: branch 1.8 r323669 - /branches/1.8/main/event.c

[SVN commits to the Digium repositories]

Author: rmudgett

New Revision: 323669

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=323669
Log:
[regression] Voicemail MWI is no longer sent.

When leaving a voicemail, the MWI message is never sent.  The same thing
happens when checking a voicemail and marking it as read.

If you restart Asterisk, everything comes up at that state correctly, but
changes to the messages in voicemail causes the light to not be set
appropriately.  Very easy to reproduce.

* Made ast_event_check_subscriber() return TRUE if there are ANY
subscribers to an event type when there are no restricting ie values
passed.  This allows an event being queued to be queued.

(closes issue ASTERISK-18002)
