Adding this method to Foswiki::Engine::Apache::MP20 seems to make everything happy:

<verbatim class="perl">
sub new {
    my $proto = shift;
    my $class = ref($proto) || $proto;
    my $this  = {};
    return bless $this, $class;
}
</verbatim>

Which is a bit odd, given that this ISA =Foswiki::Engine::Apache2= which itself ISA =Foswiki::Engine::Apache= which ISA =Foswiki::Engine= that implements =new()=...

Don't you have to at least do a =$this = $class->SUPER::new()= ?

-- %USERSWEB%.CrawfordCurrie - 11 Jun 2010


Paul,

How did you configure apache?
There should be something like:
<verbatim>
   PerlResponseHandler Foswiki::Engine::Apache
</verbatim>

-- %USERSWEB%.GilmarSantosJr - 11 Jun 2010


Crawford, the superclass does not implement new either (still get missing method error).

Gilmar, yes, this is the line, as per Support.ApacheConfigGenerator

-- %USERSWEB%.PaulHarvey - 12 Jun 2010


I just installed !ModPerlEngineContrib (from trunk) on a clean checkout and it worked well.
=tools/mod_perl_startup.pl= loads =Foswiki::Engine::Apache=, that adjusts =$Foswiki::{Engine}= to =Foswiki::Engine::Apache2::MP20= (in my environment). This one loads =Foswiki::Engine::Apache2=. =Foswiki::Engine::Apache= was already loaded, so was =Foswiki::Engine=. It's very strange... try to test on a clean checkout and report the steps to reproduce, if the bug still shows.

I'm using Apache 2.2.15 with mod_perl 2.0.4 (Debian unstable).

-- %USERSWEB%.GilmarSantosJr - 12 Jun 2010


[[http://perl.apache.org/docs/2.0/user/config/config.html#C_PerlRequire_][mod_perl documentation]] has this to say about the use of =PerlRequire=:
<blockquote>PerlRequire does the same thing as PerlPostConfigRequire, *but you have almost no control of when this code is going to be executed.* Therefore you should be using either PerlConfigRequire (executes immediately) or PerlPostConfigRequire (executes just before the end of the server startup) instead. Most of the time you want to use the latter.</blockquote> (emphasis mine)

I think my problem is related the order in which my apache2 servers are loading various modules. Today I am on a new test host and have been getting the same problems.

Replacing the =PerlRequire= had interesting results:
   * =PerlRequire= - failed to start, stupid error message: <pre>[error] Can't load Perl file: /usr/.../tools/mod_perl_startup.pl for server foo.org.au:0, exiting...</pre>, but *works after adding 'missing' new() method*
   * =PerlModule= - success starting, success accessing wiki
   * =PerlLoadModule= - success starting, success accessing wiki
   * =PerlConfigRequire= - failed to start apache2 (same error as =PerlRequire=), but *success after after adding the 'missing' new() method*
   * =PerlPostConfigRequire= - failed to start apache2 (same as =PerlRequire=), but *success after after adding the 'missing' new() method*

Obviously we need to fix Support.ApacheConfigGenerator (and Support.NewApacheConfigGenerator). Any ideas?
