# match_field() is a CGI wrapper for the match() function.
#
# Here's what it does:
#
# 1. Accepts a list of fields along with whether they may take multiple values
# 2. Takes the values of those fields from $::FORM and passes them to match()
# 3. Checks the results of the match and displays confirmation or failure
# messages as appropriate.
#
# The confirmation screen functions the same way as verify-new-product and
# confirm-duplicate, by rolling all of the state information into a
# form which is passed back, but in this case the searched fields are
# replaced with the search results.
#
# The act of displaying the confirmation or failure messages means it must
# throw a template and terminate. When confirmation is sent, all of the
# searchable fields have been replaced by exact fields and the calling script
# is executed as normal.
#
# match_field must be called early in a script, before anything external is
# done with the form data.
#
# In order to do a simple match without dealing with templates, confirmation,
# or globals, simply calling Bugzilla::User::match instead will be
# sufficient.
# How to call it:
#
# Bugzilla::User::match_field ({
# 'field_name' => { 'type' => fieldtype },
# 'field_name2' => { 'type' => fieldtype },
# [...]
# });

=head1 NAME
Bugzilla::User - Object for a Bugzilla user
=head1 SYNOPSIS
use Bugzilla::User;
my $user = new Bugzilla::User($id);
=head1 DESCRIPTION
This package handles Bugzilla users. Data obtained from here is read-only;
there is currently no way to modify a user from this package.
Note that the currently logged in user (if any) is available via
L<Bugzilla-E<gt>user|Bugzilla/"user">.
=head1 METHODS
=over 4
=item C<new($userid)>
Creates a new C{Bugzilla::User> object for the given user id. If no user
id was given, a blank object is created with no user attributes.
If an id was given but there was no matching user found, undef is returned.
=begin undocumented
=item C<new_from_login($login)>
Creates a new C<Bugzilla::User> object given the provided login. Returns
C<undef> if no matching user is found.
This routine should not be required in general; most scripts should be using
userids instead.
This routine and C<new> both take an extra optional argument, which is
passed as the argument to C<derive_groups> to avoid locking. See that
routine's documentation for details.
=end undocumented
=item C<id>
Returns the userid for this user.
=item C<login>
Returns the login name for this user.
=item C<email>
Returns the user's email address. Currently this is the same value as the
login.
=item C<name>
Returns the 'real' name for this user, if any.
=item C<showmybugslink>
Returns C<1> if the user has set his preference to show the 'My Bugs' link in
the page footer, and C<0> otherwise.
=item C<identity>
Retruns a string for the identity of the user. This will be of the form
C<name E<lt>emailE<gt>> if the user has specified a name, and C<email>
otherwise.
=item C<nick>
Returns a user "nickname" -- i.e. a shorter, not-necessarily-unique name by
which to identify the user. Currently the part of the user's email address
before the at sign (@), but that could change, especially if we implement
usernames not dependent on email address.
=item C<queries>
Returns an array of the user's named queries, sorted in a case-insensitive
order by name. Each entry is a hash with three keys:
=over
=item *
name - The name of the query
=item *
query - The text for the query
=item *
linkinfooter - Whether or not the query should be displayed in the footer.
=back
=item C<flush_queries_cache>
Some code modifies the set of stored queries. Because C<Bugzilla::User> does
not handle these modifications, but does cache the result of calling C<queries>
internally, such code must call this method to flush the cached result.
=item C<groups>
Returns a hashref of group names for groups the user is a member of. The keys
are the names of the groups, whilst the values are the respective group ids.
(This is so that a set of all groupids for groups the user is in can be
obtained by C<values(%{$user->groups})>.)
=item C<in_group>
Determines whether or not a user is in the given group. This method is mainly
intended for cases where we are not looking at the currently logged in user,
and only need to make a quick check for the group, where calling C<groups>
and getting all of the groups would be overkill.
=item C<can_see_bug(bug_id)>
Determines if the user can see the specified bug.
=item C<derive_groups>
Bugzilla allows for group inheritance. When data about the user (or any of the
groups) changes, the database must be updated. Handling updated groups is taken
care of by the constructor. However, when updating the email address, the
user may be placed into different groups, based on a new email regexp. This
method should be called in such a case to force reresolution of these groups.
=item C<get_selectable_products(by_id)>
Returns an alphabetical list of product names from which
the user can select bugs. If the $by_id parameter is true, it returns
a hash where the keys are the product ids and the values are the
product names.
=item C<get_userlist>
Returns a reference to an array of users. The array is populated with hashrefs
containing the login, identity and visibility. Users that are not visible to this
user will have 'visible' set to zero.
=item C<flatten_group_membership>
Accepts a list of groups and returns a list of all the groups whose members
inherit membership in any group on the list. So, we can determine if a user
is in any of the groups input to flatten_group_membership by querying the
user_group_map for any user with DIRECT or REGEXP membership IN() the list
of groups returned.
=item C<visible_groups_inherited>
Returns a list of all groups whose members should be visible to this user.
Since this list is flattened already, there is no need for all users to
be have derived groups up-to-date to select the users meeting this criteria.
=item C<visible_groups_direct>
Returns a list of groups that the user is aware of.
=begin undocumented
This routine takes an optional argument. If true, then this routine will not
lock the tables, but will rely on the caller to have done so itsself.
This is required because mysql will only execute a query if all of the tables
are locked, or if none of them are, not a mixture. If the caller has already
done some locking, then this routine would fail. Thus the caller needs to lock
all the tables required by this method, and then C<derive_groups> won't do
any locking.
This is a really ugly solution, and when Bugzilla supports transactions
instead of using the explicit table locking we were forced to do when thats
all MySQL supported, this will go away.
=end undocumented
=item C<can_bless>
Returns C<1> if the user can bless at least one group. Otherwise returns C<0>.
=item C<set_flags>
=item C<get_flag>
User flags are template-accessible user status information, stored in the form
of a hash. For an example of use, when the current user is authenticated in
such a way that they are allowed to log out, the 'can_logout' flag is set to
true (1). The template then checks this flag before displaying the "Log Out"
link.
C<set_flags> is called with any number of key,value pairs. Flags for each key
will be set to the specified value.
C<get_flag> is called with a single key name, which returns the associated
value.
