I didn't test 1.7.3, but after testing 1.7.4 I compared its installation directory with 1.7.2 and noticed that lib/apache2/modules/ now contains mod_dontdothat.so.
The change was made in 1.7.3. CHANGES: "General: ship mod_dontdothat with the standard release". Log message: ------------------------------------------------------------------------ r1239695 | danielsh | 2012-02-02 16:13:20 +0000 (Thu, 02 Feb 2012) | 13 lines Merge the r1207555 group from trunk: * r1207555, r1207808 mod_dontdothat: contrib/ -> tools/ and relicense under ALv2. Justification: ASF infra is using this so we should maintain it. Stuff in contrib/ isn't officially maintained. Notes: r1207555: Perform the move (from r1207550) and relicense r1207808: Enable building mod_dontdothat from our standard make scripts. Votes: +1: rhuijben, stsp, cmpilato ------------------------------------------------------------------------ It is installed by "make install" and not by "make install-tools". That looks like a bug, because I think "make install" should (a) not change in a point release and (b) not install any "tools". Thoughts? - Julian
