=head1 NAME

Bugzilla::Webservice::Group - The API for creating, changing, and getting
information about Groups.

=head1 DESCRIPTION

This part of the Bugzilla API allows you to create Groups and
get information about them.

=head1 METHODS

See L<Bugzilla::WebService> for a description of how parameters are passed,
and what B<STABLE>, B<UNSTABLE>, and B<EXPERIMENTAL> mean.

Although the data input and output is the same for JSONRPC, XMLRPC and REST,
the directions for how to access the data via REST is noted in each method
where applicable.

=head1 Group Creation and Modification

=head2 create

B<UNSTABLE>

=over

=item B<Description>

This allows you to create a new group in Bugzilla.

=item B<REST>

Some params must be set, or an error will be thrown. These params are

=item C<user_regexp>

C<string> A regular expression. Any user whose Bugzilla username matches
this regular expression will automatically be granted membership in this group.

=item C<is_active>

C<boolean> C<True> if new group can be used for bugs, C<False> if this
is a group that will only contain users and no bugs will be restricted
to it.

=item C<icon_url>

C<string> A URL pointing to a small icon used to identify the group.
This icon will show up next to users' names in various parts of Bugzilla
if they are in this group.

=back

=item B<Returns>

A hash with one element, C<id>. This is the id of the newly-created group.

=item B<Errors>

=over

=item 800 (Empty Group Name)

You must specify a value for the C<name> field.

=item 801 (Group Exists)

There is already another group with the same C<name>.

You must specify a value for the C<description> field.

=item 803 (Group Regexp Invalid)

You specified an invalid regular expression in the C<user_regexp> field.

=back

=item B<History>

=over

=item REST API call added in Bugzilla B<5.0>.

=head2 update

B<UNSTABLE>

This allows you to update a group in Bugzilla.

=item B<REST>

PUT /rest/group/<group_name_or_id>

The params to include in the PUT body as well as the returned data format,
are the same as below. The C<ids> param will be overridden as it is pulled

this perl regular expression.

=item C<is_active>

C<boolean> Set if groups are active and eligible to be used for bugs.
True if bugs can be restricted to this group, false otherwise.

=item C<icon_url>

C<string> A URL pointing to an icon that will appear next to the name of

with two keys:

=item C<added>

C<string> The values that were added to this field,
possibly a comma-and-space-separated list if multiple values were added.

=item C<removed>

C<string> The values that were removed from this field, possibly a
comma-and-space-separated list if multiple values were removed.
