Question

I’m using Devel::Cover to collect my perl coverage on linux but i got a problem when i tried to switch users. Following are steps to reproduce:

1. having 2 users : user1 and user2 and set $PERL5OPT=-MDevel::Cover=-db,[path to coverage folder]
2. login as user1 and place a test.pl at /home/user1/
3. run perl/home/user1/test.pl
4. switch to user2 by run "sudo su - user2"

error message "Devel::Cover: Can't open test.pl for MD5 digest: No such file or directory"is seen right after the user is changed

I tried getting it work by setting the arguments in PERL5OPT like:

export PERL5OPT=-MDevel::Cover=-db,[path to coverage folder],+inc,/var/home,/home

But it didn’t work, can anyone help?

Answer 1

well, finally i figured out a solution by myself – to only include the folder i wanted to collect the coverage information using “-dir”:

export PERL5OPT=-MDevel::Cover=-db,[path to coverage folder],-dir,[Paths of perl scripts to cover]
