in thread apache 2.4 mod_perl permission denied on standard modules

Nope, no copies of Digest/SHA.pm anywhere else

If I manually add

require "/usr/lib/perl5/5.18.2/x86_64-linux-thread-multi/Digest/SHA.pm +";

in a BEGIN block, the error in the apache log changes to:

Can't locate Fcntl.pm: Permission denied at /usr/lib/perl5/5.18.2/x +86_64-linux-thread-multi/Digest/SHA.pm line 7.

If I also add an explicit

use lib '/usr/lib/perl5/5.18.2/x86_64-linux-thread-multi/'

It ends up with:

Can't locate integer.pm: Permission denied at /usr/lib/perl5/5.18.2/ +x86_64-linux-thread-multi/Digest/SHA.pm line 8

With this BEGIN block:

BEGIN { foreach (@INC) { use lib $_; } }

which I think should be pretty much a noop (I also tried with reverse @inc, same result) I end up with:

Can't locate Carp.pm: Permission denied at /usr/lib/perl5/5.18.2/x86 +_64-linux-thread-multi/lib.pm line 25

And of course Carp.pm is there

    This really sounds as if there is at least one entry in @INC which is not readable for the user Apache is running as. As soon as Perl encounters such a directory, it will stop searching. So you should make sure that the relevant directories you have in @INC appear before the bad ones where the user does not have read permissions.

      Gah I wish I'd known this:

      As soon as Perl encounters such a directory, it will stop searching/

      Found a directory in INC that was readable but not executable; changed to 755 and we're past the issue.

      Still have to figure out why that directory is in INC in the first place; it's not in there when I check INC from the shell, and I don't see it anywhere in the apache config.

      But things are working now. Thanks to both of you!

        Hmm... you are right about that, and it certainly is not intuitive that Perl would “stop searching.”   Thanks for pointing that out.
