[svn-commits] tilghman: branch 1.4 r160558 - /branches/1.4/pbx/pbx_spool.c

[SVN commits to the Digium repositories]

Author: tilghman

New Revision: 160558

URL: http://svn.digium.com/view/asterisk?view=rev&rev=160558
Log:
If an entry is added to the directory during a scan when another entry expires,
then that new entry will not be processed promptly, but must wait for either a
future entry to start or a current entry's retry to occur.  If no other entries
exist in the directory (other than the new entries) when a bunch expire, then
the new entries must wait until another new entry is added to be processed.
This was a rather weird race condition, really.  Fixes AST-147.
