[nginx] svn commit: r4453 - in branches/stable-1.0: . src/event

[mdounin at mdounin.ru]

Author: mdounin
Date: 2012-02-05 20:06:50 +0000 (Sun, 05 Feb 2012)
New Revision: 4453

Log:
Merge of r4422:

Fixed error handling in ngx_event_connect_peer().

Previously if ngx_add_event() failed a connection was freed two times (once
in the ngx_event_connect_peer(), and again by a caller) as pc->connection was
left set.  Fix is to always use ngx_close_connection() to close connection
properly and set pc->connection to NULL on errors.

Patch by Piotr Sikora.
