# 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 the first parameter, a $cgi object
# and passes them to match()
# 3. Checks the results of the match and displays confirmation or failure
# messages as appropriate.
#
# The confirmation screen functions the same way as verify-new-product and
# confirm-duplicate, by rolling all of the state information into a
# form which is passed back, but in this case the searched fields are
# replaced with the search results.
#
# The act of displaying the confirmation or failure messages means it must
# throw a template and terminate. When confirmation is sent, all of the
# searchable fields have been replaced by exact fields and the calling script
# is executed as normal.
#
# You also have the choice of *never* displaying the confirmation screen.
# In this case, match_field will return one of the three USER_MATCH
# constants described in the POD docs. To make match_field behave this
# way, pass in MATCH_SKIP_CONFIRM as the third argument.
#
# match_field must be called early in a script, before anything external is
# done with the form data.
#
# In order to do a simple match without dealing with templates, confirmation,
# or globals, simply calling Bugzilla::User::match instead will be
# sufficient.
# How to call it:
#
# Bugzilla::User::match_field($cgi, {
# 'field_name' => { 'type' => fieldtype },
# 'field_name2' => { 'type' => fieldtype },
# [...]
# });
#
# fieldtype can be either 'single' or 'multi'.

=head1 NAME
Bugzilla::User - Object for a Bugzilla user
=head1 SYNOPSIS
use Bugzilla::User;
my $user = new Bugzilla::User($id);
my @get_selectable_classifications =
$user->get_selectable_classifications;
# Class Functions
$password = insert_new_user($username, $realname, $password, $disabledtext);
=head1 DESCRIPTION
This package handles Bugzilla users. Data obtained from here is read-only;
there is currently no way to modify a user from this package.
Note that the currently logged in user (if any) is available via
L<Bugzilla-E<gt>user|Bugzilla/"user">.
=head1 CONSTANTS
=over
=item C<USER_MATCH_MULTIPLE>
Returned by C<match_field()> when at least one field matched more than
one user, but no matches failed.
=item C<USER_MATCH_FAILED>
Returned by C<match_field()> when at least one field failed to match
anything.
=item C<USER_MATCH_SUCCESS>
Returned by C<match_field()> when all fields successfully matched only one
user.
=item C<MATCH_SKIP_CONFIRM>
Passed in to match_field to tell match_field to never display a
confirmation screen.
=back
=head1 METHODS
=over 4
=item C<new($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.
=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<disabledtext>
Returns the disable text of the user, if any.
=item C<settings>
Returns a hash of hashes which holds the user's settings. The first key is
the name of the setting, as found in setting.name. The second key is one of:
is_enabled - true if the user is allowed to set the preference themselves;
false to force the site defaults
for themselves or must accept the global site default value
default_value - the global site default for this setting
value - the value of this setting for this user. Will be the same
as the default_value if the user is not logged in, or if
is_default is true.
is_default - a boolean to indicate whether the user has chosen to make
a preference for themself or use the site default.
=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-E<gt>groups})>.)
=item C<groups_as_string>
Returns a string containing a comma-seperated list of numeric group ids. If
the user is not a member of any groups, returns "-1". This is most often used
within an SQL IN() function.
=item C<in_group>
Determines whether or not a user is in the given group by name.
=item C<in_group_id>
Determines whether or not a user is in the given group by id.
=item C<bless_groups>
Returns an arrayref of hashes of C<groups> entries, where the keys of each hash
are the names of C<id>, C<name> and C<description> columns of the C<groups>
table.
The arrayref consists of the groups the user can bless, taking into account
that having editusers permissions means that you can bless all groups, and
that you need to be aware of a group in order to bless a group.
=item C<can_see_user(user)>
Returns 1 if the specified user account exists and is visible to the user,
0 otherwise.
=item C<can_see_bug(bug_id)>
Determines if the user can see the specified bug.
=item C<derive_regexp_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_selectable_classifications>
Description: Returns the classifications that a user, according his
groups ownership, can select to entering, serch, view or
edit a bug.
Params: none.
Returns: Bugzilla::Classification objects values.
=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.
=item C<visible_groups_as_string>
Returns the result of C<visible_groups_direct> as a string (a comma-separated
list).
=item C<product_responsibilities>
Retrieve user's product responsibilities as a list of hashes.
One hash per Bugzilla component the user has a responsibility for.
These are the hash keys:
=over
=item productname
Name of the product.
=item componentname
Name of the component.
=item initialowner
User ID of default assignee.
=item initialqacontact
User ID of default QA contact.
=back
=item C<can_bless>
When called with no arguments:
Returns C<1> if the user can bless at least one group, returns C<0> otherwise.
When called with one argument:
Returns C<1> if the user can bless the group with that name, returns
C<0> otherwise.
=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.
=item C<wants_bug_mail>
Returns true if the user wants mail for a given bug change.
=item C<wants_mail>
Returns true if the user wants mail for a given set of events. This method is
more general than C<wants_bug_mail>, allowing you to check e.g. permissions
for flag mail.

=head1 CLASS FUNCTIONS
These are functions that are not called on a User object, but instead are
called "statically," just like a normal procedural function.
=over 4
=item C<insert_new_user>
Creates a new user in the database.
Params: $username (scalar, string) - The login name for the new user.
$realname (scalar, string) - The full name for the new user.
$password (scalar, string) - Optional. The password for the new user;
if not given, a random password will be
generated.
$disabledtext (scalar, string) - Optional. The disable text for the new
user; if not given, it will be empty.
If given, the user will be disabled,
meaning the account will be
unavailable for login.
Returns: The password for this user, in plain text, so it can be included
in an e-mail sent to the user.
=item C<is_available_username>
Returns a boolean indicating whether or not the supplied username is
already taken in Bugzilla.
Params: $username (scalar, string) - The full login name of the username
that you are checking.
$old_username (scalar, string) - If you are checking an email-change
token, insert the "old" username that the user is changing from,
here. Then, as long as it's the right user for that token, he
can change his username to $username. (That is, this function
will return a boolean true value).
=item C<login_to_id($login)>
Takes a login name of a Bugzilla user and changes that into a numeric
ID for that user. This ID can then be passed to Bugzilla::User::new to
create a new user.
If no valid user exists with that login name, then the function will return 0.
This function can also be used when you want to just find out the userid
of a user, but you don't want the full weight of Bugzilla::User.
However, consider using a Bugzilla::User object instead of this function
if you need more information about the user than just their ID.
=item C<UserInGroup($groupname)>
Takes a name of a group, and returns 1 if a user is in the group, 0 otherwise.
