NAME

RPM::NEVRA - Parses, validates NEVRA format

VERSION

Version 0.0.4

SYNOPSIS

NEVRA is the best format to describe an RPM with full details. The problem is, rpm's handling of epoch is different from how repoquery handles epoch. rpm omits the epoch when undefined, whereas repoquery thinks epoch was insignificant. This subtle difference leads to incomplete queries such as this:

$ repoquery bind-9.10.2-2.P1.fc22.x86_64
bind-32:9.10.2-2.P1.fc22.x86_64

In the above example, I had the bind package from rpm -qa, which omitted epoch because it was undefined. However, when I feed it to repoquery, it gave me back with a package with epoch of 32. This was an ambiguous query and the solution is to ALWAYS specify the epoch in repoquery queries.

use RPM::NEVRA;

my $obj = RPM::NEVRA->new();
my %info = $obj->parse_nevra('bind-32:9.10.2-2.P1.fc22.x86_64');
print $info{epoch}; # prints 32

my $is_nevra = $obj->is_nevra('bind-9.10.2-2.P1.fc22.x86_64'); # returns ( 0, 'epoch' ) since it is missing epoch
my $str = $obj->convert_to_nevra('bind-9.10.2-2.P1.fc22.x86_64'); # returns 'bind-0:9.10.2-2.P1.fc22.x86_64'
