Re: Fwd: installed Mail::SPF reports/compares version incorrectly in cpan

Is it likely that M::B 0.26's META.yml generator is badly interacting
with version.pm-based version numbers (`use version; our $VERSION =
qv('2.004');`) and CPAN is really expecting a version.pm-style version
number in META.yml (here: v2.004)?  Or why would CPAN report a
 version mismatch for v2.004 vs 2.004000?

That seems possible.  I don't have a 0.26 M::B handy, but your Mail::SPF 
META.yml has version: 2.00400 and mine are like version: v0.11.3.

The question may be whether the version.pm / CPAN code is honoring your 
VERSION line correctly.  Though, possibly that should be qv('v2.4.0').  
John?

If it compares a version object to your META.yml, I think that should be 
good.  If it is doing a string-compare, I think all bets are off.

Aside:  I'm thinking of changing most of my modules to simply say 
$VERSION = v0.1.2 just to see what breaks.  So far, it appears to be 
less of an issue than the version.pm docs imply, at least back to 5.6.2 
or so.

Yeah, me neither.

Here's what MakeMaker does, which is pretty close to that, but  
doesn't invoke the shell:


if ($value =~ m/^~(\w+)?/) { # tilde with optional username
$value =~ s [^~(\w*)]
[$1 ?
 ((getpwnam($1))[7] || ~$1) :
 (getpwuid($))[7]
 ]ex;
}

We should probably just steal it out of there, since at least then  
we'll be consistent.


Can you verify that on Windows (getpwuid $)[7] returns $ENV{HOME} if  
set?  Or at least something reasonable?  Or even if it doesn't, we  
can easily just override _detildefy in the Windows subclass.
