634824 - DUMP_MODULES fails on Gentoo-style Apache2 configuration

Status: NEW

(Bugzilla :: Installation & Upgrading, defect, P4)

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.102 Safari/534.13
Build Identifier: 

When I run checksetup.pl, I get:

WARNING: We could not check the configuration of Apache. This sometimes
happens when you are not running checksetup.pl as root. To see the
problem we ran into, run: /usr/sbin/apache2 -t -D DUMP_MODULES

I investigated, and determined that because Gentoo had 

APACHE2_OPTS="-D DEFAULT_VHOST -D DAV -D DAV_FS -D PHP5 -D INFO -D LANGUAGE -D SSL -D SSL_DEFAULT_VHOST -D SUEXEC -D PERL -D PROXY"

in /etc/conf.d/apache2, I needed to have all those defines on the command line to get it to report the modules loaded, instead of failing on things like SSL, etc.

Reproducible: Always

Steps to Reproduce:
1. Run ./checkconfig.pl on a Gentoo system
2. Try manually running the command: /usr/sbin/apache2 -t -D DUMP_MODULES
3. Realize that with all the other -D it will work
Actual Results:  
checkconfig.pl can't tell me if the modules are loaded or not; I had to manually check.

Expected Results:  
checkconfig could perhaps have an easy to edit line where I could add the defines, read that file, or otherwise find the modules loaded.

This is a minor issue, but perhaps it will help someone else who runs into it. I couldn't figure out why apache2 was working fine, but  /usr/sbin/apache2 -t -D DUMP_MODULES wouldn't run until I realized it was ignoring /etc/conf.d/apache2 so it wasn't getting any defines.

  Wow, that is a really odd way for a distro to configure Apache.

  How would you normally check the configuration of Apache from the command line, on your distro?

Comment 2

I'm not sure. The check I run is:

apache2ctl configdump

which gives me:


# apache2ctl configdump
/usr/sbin/apache2 started with '-D DEFAULT_VHOST -D DAV -D DAV_FS -D PHP5 -D INFO -D LANGUAGE -D SSL -D SSL_DEFAULT_VHOST -D SUEXEC -D PERL -D PROXY -d /usr/lib/apache2 -f /etc/apache2/httpd.conf'

then a bunch of config stuff, and then:
