Subject svn commit: r515565 - /httpd/httpd/trunk/support/logresolve.c
Date Wed, 07 Mar 2007 13:44:16 GMT
Author: jorton
Date: Wed Mar  7 05:44:15 2007
New Revision: 515565

URL: http://svn.apache.org/viewvc?view=rev&rev=515565
Log:
* support/logresolve.c (main): Simplify to avoid conditionals in handling
of lines without spaces: ensure a newline is printed for the cache-hit
path and fix a crash in apr_file_printf for the cache-miss path.
