  Wed Aug 23 01:24:54 2006 mschwern [...] cpan.org - Ticket created
Subject: CPAN::Shell->install and CPAN::Shell->expandany($mod)->install are not the same.
The docs claim... CPAN::Shell->install($mod); # same thing CPAN::Shell->expandany($mod)->install; # same thing CPAN::Shell->expand("Module",$mod)->install; # same thing CPAN::Shell->expand("Module",$mod) ->distribution->install; # same thing But they're not. The first calls (I believe) CPAN::Bundle->install and the rest call (I believe) CPAN::Distribution->install. The important difference appears to be that CPAN::Bundle->install calls rematein() while CPAN::Distribution->install does not. Without this, following prerequisites does not work. For some reason when CPAN::Shell->expandany($mod)->install; is used unsat_prereq is called twice during a module's installation, sponsored_mods is already set and CPAN.pm thinks something else is already taking care of it. See [rt.cpan.org 21139] for an example of a problem this caused.

I cannot follow your argument, I'm missing a prove. Show quoted text

When I see $obj->force('install') I jump out of the window because I cannot imagine what this should do. Is this documented anywhere? The other thing is that my $rv = $obj->install || eval ...; is always wrong thing to do. install() does not give a meaningful return value and I regret that this was never well documented. -- andreas

*shoves foot in door* Not so fast Mister. Here's a simple example. $ sudo perl -MCPAN -we 'CPAN::Shell->expand( Module => shift )->install;' File::Find::Rule vs $ sudo perl -MCPAN -we 'CPAN::Shell->install(shift);' File::Find::Rule Note that the former does not do dependency resolution. If any of File::Find::Rule's dependencies are not installed it will simply stop. The latter will install File::Find::Rule's dependencies. The docs claim they are the same thing. They are not. This lead to a bug in Module::AutoInstall (see rt.cpan.org 21139) where it was not installing dependencies.

Bang! Now I'm impressed. I forgot about the Queue. Will fix before the next release. In which direction is not yet clear. -- andreas
