Subject svn commit: r832434 - in /httpd/httpd/trunk: ./ server/mpm/ server/mpm/event/ server/mpm/mpmt_os2/ server/mpm/prefork/ server/mpm/simple/ server/mpm/winnt/ server/mpm/worker/
Date Tue, 03 Nov 2009 14:36:49 GMT
Author: trawick
Date: Tue Nov  3 14:36:48 2009
New Revision: 832434

URL: http://svn.apache.org/viewvc?rev=832434&view=rev
Log:
Change the configure-based MPM build mechanism to support building
an MPM as a shared shared or dynamic module, primarily using the
APACHE_MPM_MODULE() function.

--enable-mpms-shared now builds/installs the MPMs as dynamic modules.
(But no LoadModule directives are added.)
