Or even better -- use Apache::VMonitor :)

Leo, have you by chance read the suggestion that was printed out when 
'make test' has aborted. Please try again and do exactly what it suggested.

I can't reproduce that. Could you please try to debug that code? It's just 
perl in Makefile.PL.

Also I suspect that it might something to do with the fact that you have 
httpd-2.0 as a sub-dir of modperl-2.0? But I can't tell where the 
modperl-2.0 source lives from your report. So it's just an idea.

Yes because calling the shell is fairly slow if there are any 
perl-modules you could use these instead and it will certainly give you 
a performance boost.

tried that with perl -d Makefile.PL MP_AP_PREFIX=$HOME/mp-test/httpd-2.0

looks like it stops here:

171:        unless ($val) {
  DB<129> s
Apache::Build::apxs(lib/Apache/Build.pm:173):
173:            my $error = qx($apxs  <at> _ 2>&1);
  DB<131> s
Can't exec "/home/mgorb/mp-test/httpd-2.0/bin/apxs": No such file or 
directory at lib/Apache/Build.pm line 173.
 at lib/Apache/Build.pm line 173
        Apache::Build::apxs('Apache::Build=HASH(0x8d7fcb8)', '-q', 
'INCLUDEDIR') called at lib/Apache/Build.pm line 82
        Apache::Build::ap_prefix_invalid('Apache::Build=HASH(0x8d7fcb8)') 
called at Makefile.PL line 206
        main::configure() called at Makefile.PL line 52

...

looking into /home/mgorb/mp-test/httpd-2.0/bin/apxs ( which appeared to be 
a perl script :) ) showed "#!/replace/with/path/to/perl/interpreter -w" at 
the first line. Replaced it with "/usr/local/bin/perl". After that "perl 
Makefile.PL" worked and mp2 was built OK, but some tests failed:

Why doesn't it print out the error then?

PerlCleanupHandler and redirect

I am having a problem with using a cleanup handler where it seems that
the CleanupHandler is blocking the client browser from a redirect

From what i understand the cleanup handler happens after the
connection is closed.

I am using the cleanup handler to do some lengthy processing while the
user is redirected to a wait page.

i am registering the handler like so:
$r->register_cleanup('MyPackage::LongProcess');

if i have the handler return right away instead of doing any processing,
the client is redirected right away otherwise it blocks until the
handler returns
which happens after the client times out.

has anyone else experienced this kind of behavior?

any info or pointers is greatly appreciated!
Thanks,

ANNOUNCE: Krang 1.025


Krang v1.025 is now available.  Notable changes in this release:

  - Fixes an incomplete upgrade process in 1.024.  Users who upgraded
    their Krang installations to 1.024 should immediately upgrade to
    1.025.

  - Improved error handling and reporting in the command-line
    krang_publish script.

  Detailed change-log here: http://krang.sf.net/docs/changelog.html

  Krang is an Open Source web-publisher / content-management system
  designed for large-scale magazine-style websites.  It is a 100% Perl
  application using Apache/mod_perl and MySQL, as well as numerous CPAN
  modules.

  Krang provides a powerful and easy to use story and media editing
  environment for magazine editors, as well as a complete template
  development environment for web designers. On the back-end, Perl
  programmers can customize Krang to control the data entered in the
  story editor and add code to drive the templates to build output.
  Krang can be enhanced with add-ons containing new skins and other new
  features.  Krang easily handles large data sets and can manage
  multiple websites in a single installation.

Re: SOAP::Lite, libapreq not playing together?

Perhaps I'm missing something in what you're trying to do, but you might
try Apache::SOAP.  Apache::SOAP makes it super-easy to call perl
subroutines running under mod_perl.

I have something like this in my apache config, which maps requests to a
Perl module:

    <Location "/soaptest">
        SetHandler perl-script
        PerlHandler Apache::SOAP
        PerlSetVar dispatch_to "Some::Module"
    </Location>

and then, my module:

	package Some::Module;

	sub add {
		my ($val1, $val2) =  <at> _;
		my $result = $val1 + $val2;
		return $result;		
	}
	
	sub subtract {
		my ($val1, $val2) =  <at> _;
		my $result = $val1 - $val2;
		return $result;		
	}
	1;
