Subject:

CGI::Carp::croak caller stack missing

If I use Carp croak shoes the caller stack. Then I write a CGI-Application and Carp is different, why? So I can't find errors croak is like die.

I'm sorry it took almost 4 years to get a reply through the bug tracker. I think your experience is due to the interaction between Carp and CGI::Carp. I'm marking this bug as "rejected" for now because no one else has complained in the last 4 years, and I don't think it's a CGI bug. If there's still something you'd like changed in CGI.pm, please submit a Test::More style test case which illustrates it, or other steps to reproduce it. Mark

Here is the t-script that does not fail using Carp and not CGI::Carp. --------------------------------------------------------------------- use strict; use warnings; use Test::More tests => 2; use Test::Exception; BEGIN { use_ok('CGI::Carp', qw(croak) ); } sub cr { croak 'croak' } throws_ok( sub { cr() }, qr{\A croak \s at \s .*? \s at \s}xms, 'croak shows the caller stack', );

Here's a refactor of the test that avoids the dependency on Test::Exception: ### use strict; use warnings; use Test::More 'no_plan'; use CGI::Carp 'croak'; eval { croak 'croak' }; like($@, qr{\A croak \s at \s .*? \s at \s}xms, 'croak shows the caller stack'); ### I'm still hoping someone else will provide the actual bug fix.

No one else has expressed interest in this since 2009 or supplied a patch, so I'm marking this as resolved-due-to-old-age.
