Subject svn commit: r987532 - in /apr/apr/branches/1.5.x: ./ network_io/unix/sockets.c test/testsock.c
Date Fri, 20 Aug 2010 14:59:16 GMT
Author: rpluem
Date: Fri Aug 20 14:59:15 2010
New Revision: 987532

URL: http://svn.apache.org/viewvc?rev=987532&view=rev
Log:
Merge r983618 from trunk:

* network_io/unix/sockets.c (apr_socket_connect): Copy the remote
  address by value rather than by reference.  This ensures that the
  sockaddr object returned by apr_socket_addr_get is allocated from
  the same pool as the socket object itself, as apr_socket_accept
  does; avoiding any potential lifetime mismatches.

* test/testsock.c (test_get_addr): Enhance test case to cover this.
