Thanks for the clarification. In other words: avoid Win32::OLE in modperl? Jan Dubois wrote: On Fri, 08 Jun 2007, Foo JH wrote: I wonder if I am alone in experiencing this.

Using Win32::OLE in a multi-threaded way is generally not safe. It is definitely not working correctly if you use the threads.pm module or fork() emulation. It could potentially work in a multi-threaded environment if each interpreter is created independently (not using perl_clone()). When using the COM apartment threading model then each interpreter also needs to be bound to a specific thread, as it is then invalid to invoke methods on a COM object from any other thread than the one that created it.

It is definitely not working correctly if you use the threads.pm module or fork() emulation. It could potentially work in a multi-threaded environment if each interpreter is created independently (not using perl_clone()). When using the COM apartment threading model then each interpreter also needs to be bound to a specific thread, as it is then invalid to invoke methods on a COM object from any other thread than the one that created it.

Re: Loading Win32::OLE in a modperl package
Hi again,
I tried our code, using as well this directive in my httpd.conf file:
PerlResponseHandler MyPackage
To make your handler work as the main Response Handler.
Moreover I had to alter your code to make it work, adding a:
use Apache2::RequestRec;
because otherwise, the content_type method is not defined.
And it worked perfectly (returning 'hello';)
#**
package MyPackage;
use strict;
use warnings;
use Win32::OLE;
use Apache2::RequestRec;
sub handler
{
my $r = shift;
$r->content_type('text/plain');
print 'hello';
return Apache2::Const::OK;
}
1;
#**
For your information, I am using:
Apache/2.0.59 (Win32) mod_perl/2.0.3 Perl/v5.8.8
perl and MP are ActiveState builds.
And I downloaded the Win32 binary from the Apache httpd website.
Lionel.

Thanks Lionel,
I'm running Apache2.2 + Perl5.88.
Try this piece of code:
package MyPackage;
use strict;
use warnings;
use Win32::OLE;
sub handler
{
my $r = shift;
$r->content_type('text/plain');
print 'hello';
return Apache2::Const::OK;
}

Doing, in test.pl, run by ModPel::Registry, something like:
use Win32::OLE;
print 'Hello';
Works prefectly...
Which versions (Apache, MP and Perl) are you running?

Subject: Loading Win32::OLE in a modperl package
Hi all,
I wonder if I am alone in experiencing this. Simply put: putting 'use
Win32::OLE' in my modperl package will cause the Apache to fault. It
basically can't start at all.
A window will pop up complaining about 'Apache HTTP Server has
encountered a problem and needs to close'. No entry into the error log.
Does anyone know if this can be worked around?
