Cool, but when running within the mod_perl-2.0 build environment, you end up
with a testcover target in ModPerl-Registry/Makefile and Apache-Test/Makefile,
but not in the top-level directory.

Any idea why ?

basically, this is because mod_perl sets up its own test target via MY::test
in it's top-level Makefile.PL. ModPerl-Registry/Makefile.PL inherits its
test target from Apache::Test, a la

use Apache::TestMM qw(test clean);

so, if we want to add coverage foo to mod_perl's test suite we need to do it
manually. I'm not sure it's worth the effort, though - I can't even run a
simple 5 line handler consistently under D::C, let alone the whole mp2 test
suite.

Is this because of threading, which (still) doesn't work in Devel::Cover
or is it some other kind of fundamental brokenness?

Here is where I have to admit that I am still developing with mp1, but
mp2 and Devel::Cover seemed to get on the last time I tried, which was
about 18 months ago using 1.99_13 and the bleadperl du jour. See
http://pjcj.sytes.net/cover/mod_perl-1.99_13/cover_db-5.9.2/coverage.html

my own level of understanding here really leaves me not knowing what to make
of it at all. the core dumps I've been getting haven't contained anything
useful, and I recently started getting them with mp1 as well.

in truth, my dev box is on its last legs, so I have been somewhat hoping
that that contributed to the problem as well. the reality is that I
sometimes get core dumps and sometimes don't, it sometimes works and
sometimes doesn't, just when I type 'make testcover' a few times without
doing anything else...

if it helps, whether you're using mp1 or mp2 this tarball is what I use as
my test case

http://people.apache.org/~geoff/Apache-Test-with-Devel-Cover.tar.gz

so just

$ perl Makefile.PL -httpd /path/to/whatever/httpd/you/want/1.3/or/2.x

will let you test multiple versions of httpd.

note that it's been updated to work with the latest Apache-Test (that is,
the changes that started this thread) so you'll need a recent version or
need to go fiddling with the extra files yourself.

that's ok, mp1 is still important :)

wow, that's great. if you could ever give me a hint on how to set the
compile flags to get XS coverage that would be awesom - I'd love to
intelligently add those automatically when compiling mp2 in maintainer mode
so that they show up when using A-T to test XS-based CPAN modules.
