I have a perl object with a few functions in it. Each functions is called once from the main program. I would like to run some of the functions in parallel to save time. I can't run all of them together since some functions depend on the results of previous functions. I thought of something like this: For each function keep a flag tha...

Then, it does 10000 random lookups in th...

Ideally, this would include all of the module dependencies. The end goal is to be able to deploy to a number of boxes (which only have a basic perl install) and ensure that the script has th...

When running plain perl scripts in eval or do mode it performs perfectly. As soon as I attempt to access the FCGI::Request() object or the CGI::Fast->new object, it hangs indefinitely. Here's my config: [Typ...
Let's say I have a perl module file and I want to include and use it dynamically at runtime. Said module includes a class that I need to instantiate without knowing its name until runtime. For example, #inside module.pm package module; sub new { #setup object } #inside main.pl #get module.pm as argument my $module_var = #load refe...
Anyone see anything wrong with this code? When we execute it (on Linux), we get taken straight to the "Error: Unknown host" block.

I've been looking at ways to add a Perl-based SOAP server to our systems. Every time I look @ the SOAP tools in Perl I'm disappointed at how much more developer overhead seems to be required than folks in the VS.net world. (And I've been looking for a long time) From reviewing other questions here, it looks like XML::Compile::SOAP see...

With the $CPAN::Config-method the force CPAN::FirstTime to not ...
