[svn-commits] mmichelson: branch 1.4 r77852 - /branches/1.4/apps/app_queue.c

[SVN commits to the Digium repositories]

Author: mmichelson
Date: Wed Aug  1 08:59:59 2007
New Revision: 77852

URL: http://svn.digium.com/view/asterisk?view=rev&rev=77852
Log:
If a queue uses dynamic realtime members, then the member list should be updated after each attempt to call the queue.
This fixes an issue where if a caller calls into a queue where no one is logged in, they would wait forever even if a member
logged in at some point.

(closes issue #10346, reported by and tested by blitzrage, patched by me)
