[WISHLIST] Be able to troubleshoot config file with perl -cx as before
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Dear Stas and fellow mod_perl maintainers,
I would like to be able to do the "perl -cx"-on-the-Apache-config-file
trick described in the Eagle book ("Debugging <perl> sections" in
chapter 8, page 420 in my edition but 428 in some others according to
Google), but I run across the following problem:
$ perl -e 'use strict; use Apache2; use Apache::compat;'
Bareword "Apache::ServerUtil::server_root" not allowed while "strict
subs" in use at /usr/local/lib/perl/5.6.1/Apache2/Apache/compat.pm
line 329.
BEGIN not safe after errors--compilation aborted at
/usr/local/lib/perl/5.6.1/Apache2/Apache/compat.pm line 412.
Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
And consequently perl -cx on my Apache configuration file does not
reliably syntax-check my
<perl> section.
I am running mod_perl 1.999.20, I reckon everything else is irrelevant
to this particular problem.
Regards,

It does neither, it fails at the very same place, because this is no
longer a "bareword not allowed" error (that admittedly a pair of
parens would cure) but an "undefined subroutine".

With all due respect, I don't think so.

what I meant was that does changing Apache::ServerUtil::restart_count to
Apache::ServerUtil::restart_count() fix the problem, or does it then fail
someplace else? this kind of error is simple, but it shouldn't take
iteration after iteration of patches to get it right - since you have the
environment to reproduce the issue and know the fix, apply it until the
problem either goes away or becomes something else :) if the problem goes
away post a patch and we'll apply it asap. if it becomes something else
we'll help that go away too :)

what mp2 modules fail to do so, besides Apache::compat?

I see. but since you aren't using Apache::compat during config, why not
just comment it out. I don't think the described situation justfies
rewriting this module, to s/use/require/ and remove other compile time
things, making the code a mess and losing some compile time optimizations.
The solution in fact is simple: just replace your 'use Apache::compat; with:
require Apache::compat if $ENV{MOD_PERL};
in which case it won't be loaded unless run under mod_perl.

Since they do nothing too fancy in their BEGIN blocks, all modules in
mod_perl 1 except Apache::test compile OK from /usr/bin/perl (even
though calling any of their subs could obviously fail):
$ for i in `dpkg -L libapache-mod-perl | grep 'pm$' | perl -pe
's|/usr/lib/perl5/(.*).pm|$1|; s|/|::|g;'`; do perl -M$i -e 1 ||
echo $i; done
Can't locate Apache/test.pm in @INC (@INC contains:
/usr/local/lib/perl/5.6.1 /usr/local/share/perl/5.6.1 /usr/lib/perl5
/usr/share/perl5 /usr/lib/perl/5.6.1 /usr/share/perl/5.6.1
/usr/local/lib/site_perl .).
BEGIN failed--compilation aborted.
Apache::test
Having just "Apache::Compat" compile OK in mod_perl 2 would be enough
for my needs.

This is not going to work, since it requires a running mod_perl. I'm
pretty sure the perl -cx worked in mp1 only in certain cases, where no
mod_perl symbols were used. Try the modperl1 config where you use some
Apache module and you will get the same problem.
