From: Stefan Fritsch Date: Wed, 29 Sep 2010 19:42:03 +0000 (+0000) Subject: Make the ssl expression parser thread-safe. It now requires bison instead of X-Git-Tag: 2.3.9~393 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f9ba292bfabc8bee00d15d518211ccde06a25e2f;p=apache Make the ssl expression parser thread-safe. It now requires bison instead of yacc. Also change the make file magic so that the real source file name is embedded in the debug info. The generated files have been created with flex 2.5.35/bison 2.4.1. The two 'no previous prototype' warnings are supposed to be fixed with the next flex version. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1002824 13f79535-47bb-0310-9956-ffa450edef68 --- diff --git a/CHANGES b/CHANGES index 0fec31686b..350573e44c 100644 --- a/CHANGES +++ b/CHANGES @@ -2,6 +2,9 @@ Changes with Apache 2.3.9 + *) mod_ssl: Make the ssl expression parser thread-safe.
