Description Jay Berkenbilt 2002-06-12 16:22:12 EDT
Description of Problem:

File::stat::stat(), when called on a file that does not exist, causes a message
to get printed to stderr if -w was passed to perl.  It should just return undef.
 This problem did not exist in RedHat 7.2.
Version-Release number of selected component (if applicable):


How Reproducible:


Steps to Reproduce:
1. perl -w -e 'use File::stat; stat("/does/not/exist");'

Actual Results:

stat() on unopened filehandle /does/not/exist at
/usr/lib/perl5/5.6.1/File/stat.pm line 49.

Expected Results:

No output should have been generated.

Additional Information:
No doubt perl 5.6.1 is checking for something that 5.6.0 didn't check.  The
stat.pm code is unchanged.  This patch to /usr/lib/perl/5.6.1/File/stat.pm fixes
the problem.  Locally disabling $^W is no worse that locally disabling strict
'refs', which the code already does.

I'm including it inline since it's so small, but I'll also attach it as an
attached file.

Comment 2 Chip Turner 2002-06-13 11:35:43 EDT
this is fixed in perl 5.8.0 in Rawhide.  unlikely to fix in 7.2 or 7.3, however,
unless an errata becomes necessary.
