From colin.robertson@bbc.co.uk

Getting bounces if I send with perlbug, but that may be due to our mail
server configuration, so retrying manually:

This is a bug report for perl from colin.robertson@bbc.co.uk,
generated with the help of perlbug 1.35 running under perl v5.8.8.

There is an odd inconsistency in the behaviour of Exporter and the
points at which it warns about redefining subroutines. Consider the
following modules:

-- Foo.pm --

package Foo;

use base 'Exporter';
our @EXPORT_OK = qw( foobar );

sub foobar { print "Foo\n" };

1;

-- Bar.pm --

package Bar;

use base 'Exporter';
our @EXPORT_OK = qw( foobar );

sub foobar { print "Bar\n" };

1;

-- Once.pm --

package Once;

use Foo qw( foobar );
use Bar qw( foobar );

1;

-- Twice.pm --

package Twice;

use Foo qw( foobar );
use Bar qw( foobar );

1;

-- End --

Running "perl -we 'use Once;'" gives us no warnings, but running "perl
-we 'use Once; use Twice;'" gives us:

Subroutine Twice::foobar redefined at
/usr/local/lib/perl5/5.8.7/Exporter.pm line 65.
at Twice.pm line 4

Ideally, there should have been a warning just when compiling Once.

This bug, or at least something related to it, was encountered in the
wild with code that effectively did:

use File::Temp;
use File::Slurp;

(with File::Temp version 0.16 and File::Slurp version 9999.11). This
gives us the warning:

Subroutine File::Slurp::O_RDWR redefined at
/usr/local/cps_perl5.8.7/site_perl/File/Slurp.pm line 7
Subroutine File::Slurp::O_CREAT redefined at
/usr/local/cps_perl5.8.7/site_perl/File/Slurp.pm line 7
Subroutine File::Slurp::O_EXCL redefined at
/usr/local/cps_perl5.8.7/site_perl/File/Slurp.pm line 7

On the other hand, when the use statements are reversed, there is no
warning:

use File::Slurp;
use File::Temp;

I think File::Slurp should actually be warning a lot, regardless of
anything else that happens, because the following lines import a bunch
of duplicated symbols:

use Fcntl qw( :DEFAULT ) ;
use POSIX qw( :fcntl_h ) ;

It happens that File::Temp makes some use of O_RDWR, O_CREAT and 0_EXCL,
which triggers the warning in File::Slurp.

It might be this one. From perl588delta.pod:

=head2 no warnings 'category' works correctly with -w

Previously when running with warnings enabled globally via C<-w>, selective
disabling of specific warning categories would actually turn off all warnings.
This is now fixed; now C<no warnings 'io';> will only turn off warnings in the
C<io> class. Previously it would erroneously turn off all warnings.

This bug fix may cause some programs to start correctly issuing warnings.

hmm. Interesting. When I test with perl 5.8.8 on the same machine I
still get no warning with just Once.pm. I've checked %INC and it does
seem to be loading the 5.8.8 modules. I don't have any other
installations of perl 5.8.8 to play with, unfortunately, nor 5.6.2.

That seems pretty likely, since Carp::Heavy (ultimately loaded by
Exporter) has a C<no warnings "once";> in it. I believe the workaround
for this in older perls is to make sure to use warnings before anything
else. So for Colin's test, try

perl -we 'use warnings; use Once;'

And for the in-the-wild case:

use warnings;
use File::Slurp;
use File::Temp;

No, that doesn't appear to be it, unfortunately:

oh. Very different. ok, perhaps time to consider that this 5.8.8
installation is a somewhat dodgy. It's actually similar, though not
quite identical, to our 5.8.7 installation:

colinr@pandora~/projects/exporter-bug $ perl -we 'use Once; printf "%6d:
%s\n", -s, $_ for sort values %INC;'
8840: /usr/local/lib/perl5/5.8.7/Carp.pm

15793: /usr/local/lib/perl5/5.8.7/warnings.pm
1014: /usr/local/lib/perl5/5.8.7/warnings/register.pm
101: Bar.pm
101: Foo.pm
63: Once.pm

So at this stage it looks like it's something that may well be fixed in
5.8.8 and it may just be that our 5.8.8 installation is borked for one
reason or another. It doesn't appear to be the "no warnings 'category'
works correctly with -w" fix, since the problem is still there with 'use
warnings' at the start under 5.8.7. But the next thing to do is for me
to investigate this 5.8.8 installation to see if it's unhealthy.

Thanks to all of you for your help.

Getting bounces if I send with perlbug, but that may be due to our

This is a bug report for perl from colin.robertson@bbc.co.uk,
generated with the help of perlbug 1.35 running under perl v5.8.8.

There is an odd inconsistency in the behaviour of Exporter and the
points at which it warns about redefining subroutines.

Can you run the following command if the problem still exists:

perl -wle 'for (qw/Carp Exporter base strict warnings
warnings::register/) { eval "require $_"; if ($@) { print "Unable to
require $_: $@"; } print "$_ = " . ${"$_\::VERSION"} }'

Or can you tar the files and attach them?

Kind regards,

Bram
