Re: Re: developing and distributing perl apps

rdfield,

You can add a PAR file to a mod_perl configuration via the Apache::PAR module. Apache::PAR is written for exactly these kinds of situations.

Dependency checking is probably best avoided by packaging all dependent modules into the PAR file. If this isn't possible, there are a couple of other ways I think dependency checking could probably also be handled:

Make the PAR file an executable with pp and have the main script check dependencies. That way, a user could run the par file to check dependencies, but still install it on mod_perl using Apache::PAR (untested)
Using Apache::PAR, add code to the web.conf file in the PAR file using a <PERL></PERL> section which checks dependencies, and prints warnings or errors out as appropriate. Of course, this couldn't check for the existance of Apache, mod_perl, PAR or Apache::PAR, as these are prereqs for loading a web.conf

Thanks,
techy

Nathan? Is that you? :) Script reload still doesn't happen under Apache 1.3.x on Win32, but the module reload is working fine now. I haven't tested 0.30 under Apache 2.0 yet. rdfield	[reply]

rdfield, Yes, its me, always looking for a chance to put in a plug for Apache::PAR :-) I will take a look at reloading scripts under Win32. Does this happen with both Apache::PAR::Registry and Apache::PAR::PerlRun? Trying Apache 2/mod_perl 2 may be a good idea - Apache::PAR uses a very different system for running Registry/PerlRun scripts under it. In the mean time, if it is appropriate for your application you may also want to try ##UNPACKDIR## in your web.conf and using normal Apache::Registry or Apache::PerlRun config to execute the scripts, as there is also a mechanism for reloading the unpacked content for changed archives. Also, I suggest we take this offline as this is slightly OT for this discussion. Can you send me an email with the details? Thanks, techy (Nathan)	[reply]
