Bugzilla::Install::Requirements - Functions and variables dealing
|
|
with Bugzilla's perl-module requirements.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module is used primarily by C<checksetup.pl> to determine whether
|
|
or not all of Bugzilla's prerequisites are installed. (That is, all the
|
|
perl modules it requires.)
|
|
|
|
=head1 CONSTANTS
|
|
|
|
=over 4
|
|
|
|
=item C<REQUIRED_MODULES>
|
|
|
|
An arrayref of hashrefs that describes the perl modules required by
|
|
Bugzilla. The hashes have two keys, C<name> and C<version>, which
|
|
represent the name of the module and the version that we require.

=item B<Description>
|
|
|
|
This checks what optional or required perl modules are installed, like
|
|
C<checksetup.pl> does.
|
|
|
|
=item B<Params>
|
|
|
|
=over
|
|

about what it's doing, and the versions of everything installed.

|
|
|
|
=item B<Returns>
|
|
|
|
A hashref containing these values:
|
|
|
|
=over
|
|
|
|
=item C<pass> - Whether or not we have all the mandatory requirements.
|
|
|
|
=item C<missing> - An arrayref containing any required modules that
|
|
are not installed or that are not up-to-date. Each item in the array is
|
|
a hashref in the format of items from L</REQUIRED_MODULES>.
|
|
|
|
=item C<optional> - The same as C<missing>, but for optional modules.
|
|
|
|
=item C<have_one_dbd> - True if at least one C<DBD::> module is installed.
|
|
|
|
=item C<any_missing> - True if there are any missing modules, even optional
|
|
modules.

|
|
|
|
=item C<have_vers($module, $output)>
|

Description: Tells you whether or not you have the appropriate
|
|
version of the module requested. It also prints
|
|
out a message to the user explaining the check
|
|
and the result.
