Dynamic @INC under mod_perl2 (Apache2 VirtualHost)

graq has asked for the wisdom of the Perl Monks concerning the following question:

I have some mod_perl2 modules loaded in under Apache 2.0.
In order for me to set up proper development and test environments (and provide some portability to the code base) I would like to be able to set @INC by VirtualHost.

The current setup uses <Perl> use lib '/path/to/lib'</Perl> configuration, but this is loaded on Apache configuration and is shared by all VirtualHosts.

I have tried adding PerlSwitches -I/path/to/lib inside the VirtualHost (it looked like the perfect solution), but this does not appear to be sufficent for my LoadModule modules.

I appreciate that I could run a second Apache demon using the -f switch, but I would prefer to find some other way.

You almost have it. You also need the `Parent` option. See the docs for more info. `<VirtualHost ...> ServerName dev PerlOptions +Parent PerlSwitches -Mlib=/home/dev/lib/perl </VirtualHost> <VirtualHost ...> ServerName test PerlOptions +Parent PerlSwitches -Mlib=/home/test/lib/perl </VirtualHost>` [download] The intelligent reader will judge for himself.

Keeping in mind the important piece of info in the parent post is `PerlOptions +Parent`, the docs also say `-Mlib=...` is buggy on certain platforms. `-I...` does the same thing, except it doesn't remove duplicates (which is no biggy). Therefore, he should keep his `-I...` and simply add `PerlOptions +Parent`, as follows: `<VirtualHost ...> ServerName dev PerlOptions +Parent PerlSwitches -I/home/dev/lib/perl </VirtualHost> <VirtualHost ...> ServerName test PerlOptions +Parent PerlSwitches -I/home/test/lib/perl </VirtualHost>` [download] I presume his `LoadModule` needs to be placed in `<VirtualHost>` for it to work?

Thank you - I am making progress. I've setup Apache to listen on port 8080 and Included VH config file like so: Read more... (2 kB) But I get this error, despite my best efforts: `Can't locate object method "log_error" via package "Apache2::RequestRe +c" at /home/graq/lib/GRAQ/Menu.pm line 56.` [download] This all used to work with liberal smatterings of `<Perl> use lib 'home/graq/lib';</Perl>` and I'm getting a little lost on exactly what effects my changes have had on the mod_perl environment. I remember having this error when porting from mp1 to mp2, but can't find any notes on it or hints from the docs on what object I should have in `handler`...? -=( Graq )=-	[reply] [d/l] [select]

Update: Not all the virtual hosts share the same perl interpreters in mod_perl/2, so this post is incorrect. Read more... Original Post (818 Bytes)	[reply] [d/l] [select]
