Hi Thanks for the info. I'll try setting up some virtual hosts. More below... On Wed, Apr 02, 2003 at 06:07:01PM -0500, Perrin Harkins wrote: Brian C.

There is no support for pools of interpreters in mp1, so all of your code must be using the same @INC. Right, I guess it just feels like it is working under mp1, since I can get @INC to contain . (the current dir) and use StatINC in all the developer locations. In the mp2 server, it shows me a different @INC, that doesn't include . (is it possible in mp2?). Thanks again, BCT

In the mp2 server, it shows me a different @INC, that doesn't include . (is it possible in mp2?). You almost got me ;) I was looking for the place in mp2 that removes . from @INC. After awhile it struck me to check the perl source, and perl.c had: if (!PL_tainting) incpush(., FALSE, FALSE, TRUE); It's been there for a long time (tested with 5.005_03), though I didn't know/remember that :( # here you have . % perl -le 'warn join \n, @INC, ;' # and here you don't % perl -Tle 'warn join \n, @INC, ;' . is added to @INC only if you aren't running with -T. Nothing specific to mod_perl. You can still add it using: use lib qw(.); if you really have to. But it's especially bad idea with mp2/threaded mpm, where one should never use chdir during request time and rely on cwd.
