Review request for Asterisk Developers.


Changes
-------

New diff.  Added code to clean up the data returned by ast_db_gettree().


Summary
-------

This is a modified version of the patch from bug 13819 (http://bugs.digium.com/view.php?id=13819).  It spawns a thread to remove expired entries from the dundi cache (in astdb) every 60 seconds.  This patch is necessary because asterisk normally cleans these entries when they are looked up, but entries that are not retrieved often (or retrieved only once ever) will stay in the database.


This addresses bug 13819.

Diffs (updated)
-----

  /branches/1.6.0/pbx/pbx_dundi.c 158369 

Diff: http://reviewboard.digium.com/r/63/diff


Testing
-------

I tested this by creating some expired entries in the database using 'database put dundi/cache test 0|0' and observed asterisk clean them up.


Thanks,

Matthew
