Subject svn commit: r371172 - in /apr/apr/trunk: CHANGES locks/win32/thread_rwlock.c test/testlock.c
Date Sun, 22 Jan 2006 02:45:20 GMT
Author: rooneg
Date: Sat Jan 21 18:45:18 2006
New Revision: 371172

URL: http://svn.apache.org/viewcvs?rev=371172&view=rev
Log:
Fix an assert that occurs when you destroy a rwlock on win32 and later clear
the pool it was allocated from.

Submitted by: Evgueni Brevnov <evgueni.brevnov gmail.com>

* locks/win32/thread_rwlock.c
  (apr_thread_rwlock_destroy): Use apr_pool_cleanup_run to call our cleanup
   function.
  (thread_rwlock_cleanup): Put the destruction of the rwlock here instead
   of in the destructor function.

* test/testlock.c
  (test_thread_rwlocks): Destroy the rwlock explicitly so we can see this
   kind of problem.

* CHANGES: Note change.
