=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
$user = Bugzilla::User->create({
login_name => $username,
realname => $realname,
cryptpassword => $plaintext_password,
disabledtext => $disabledtext,
disable_mail => 0});
=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">.
C<Bugzilla::User> is an implementation of L<Bugzilla::Object>, and thus
provides all the methods of L<Bugzilla::Object> in addition to the
methods listed below.
=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
=head2 Constructors
=over
=item C<super_user>
Returns a user who is in all groups, but who does not really exist in the
database. Used for non-web scripts like L<checksetup> that need to make
database changes and so on.
=back
=head2 Saved and Shared Queries
=over
=item C<queries>
Returns an arrayref of the user's own saved queries, sorted by name. The
array contains L<Bugzilla::Search::Saved> objects.
=item C<queries_subscribed>
Returns an arrayref of shared queries that the user has subscribed to.
That is, these are shared queries that the user sees in their footer.
This array contains L<Bugzilla::Search::Saved> objects.
=item C<queries_available>
Returns an arrayref of all queries to which the user could possibly
subscribe. This includes the contents of L</queries_subscribed>.
An array of L<Bugzilla::Search::Saved> objects.
=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<queryshare_groups>
An arrayref of group ids. The user can share their own queries with these
groups.
=item C<tags>
Returns a hashref with tag IDs as key, and a hashref with tag 'id',
'name' and 'bug_count' as value.
=item C<bugs_ignored>
Returns an array of hashrefs containing information about bugs currently
being ignored by the user.
Each hashref contains the following information:
=over
=item C<id>
C<int> The id of the bug.
=item C<status>
C<string> The current status of the bug.
=item C<summary>
C<string> The current summary of the bug.
=back
=item C<is_bug_ignored>
Returns true if the user does not want email notifications for the
specified bug ID, else returns false.
=back
=head2 Saved Recent Bug Lists
=over
=item C<recent_searches>
Returns an arrayref of L<Bugzilla::Search::Recent> objects
containing the user's recent searches.
=item C<recent_search_containing(bug_id)>
Returns a L<Bugzilla::Search::Recent> object that contains the most recent
search by the user for the specified bug id. Retuns undef if no match is found.
=item C<recent_search_for(bug)>
Returns a L<Bugzilla::Search::Recent> object that contains a search by the
user. Uses the list_id of the current loaded page, or the referrer page, and
the bug id if that fails. Finally it will check the BUGLIST cookie, and create
an object based on that, or undef if it does not exist.
=item C<save_last_search>
Saves the users most recent search in the database if logged in, or in the
BUGLIST cookie if not logged in. Parameters are bug_ids, order, vars and
list_id.
=back
=head2 Account Lockout
=over
=item C<account_is_locked_out>
Returns C<1> if the account has failed to log in too many times recently,
and thus is locked out for a period of time. Returns C<0> otherwise.
=item C<account_ip_login_failures>
Returns an arrayref of hashrefs, that contains information about the recent
times that this account has failed to log in from the current remote IP.
The hashes contain C<ip_addr>, C<login_time>, and C<user_id>.
=item C<note_login_failure>
This notes that this account has failed to log in, and stores the fact
in the database. The storing happens immediately, it does not wait for
you to call C<update>.
=item C<set_email_enabled>
C<bool> - Sets C<disable_mail> to the inverse of the boolean provided.
=back
=head2 Other Methods
=over
=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 their preference to show the 'My Bugs' link in
the page footer, and C<0> otherwise.
=item C<identity>
Returns 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<authorizer>
This is the L<Bugzilla::Auth> object that the User logged in with.
If the user hasn't logged in yet, a new, empty Bugzilla::Auth() object is
returned.
=item C<set_authorizer($authorizer)>
Sets the L<Bugzilla::Auth> object to be returned by C<authorizer()>.
Should only be called by C<Bugzilla::Auth::login>, for the most part.
=item C<disabledtext>
Returns the disable text of the user, if any.
=item C<reports>
Returns an arrayref of the user's own saved reports. The array contains
L<Bugzilla::Reports> objects.
=item C<flush_reports_cache>
Some code modifies the set of stored reports. Because C<Bugzilla::User> does
not handle these modifications, but does cache the result of calling C<reports>
internally, such code must call this method to flush the cached result.
=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<setting(name)>
Returns the value for the specified setting.
=item C<timezone>
Returns the timezone used to display dates and times to the user,
as a DateTime::TimeZone object.
=item C<groups>
Returns an arrayref of L<Bugzilla::Group> objects representing
groups that this user is a member of.
=item C<groups_as_string>
Returns a string containing a comma-separated 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<groups_in_sql>
This returns an C<IN> clause for SQL, containing either all of the groups
the user is in, or C<-1> if the user is in no groups. This takes one
argument--the name of the SQL field that should be on the left-hand-side
of the C<IN> statement, which defaults to C<group_id> if not specified.
=item C<in_group($group_name, $product_id)>
Determines whether or not a user is in the given group by name.
If $product_id is given, it also checks for local privileges for
this product.
=item C<in_group_id>
Determines whether or not a user is in the given group by id.
=item C<bless_groups>
Returns an arrayref of L<Bugzilla::Group> objects.
The arrayref consists of the groups the user can bless, taking into account
that having editusers permissions means that you can bless all groups, and
that you need to be able to see a group in order to bless it.
=item C<get_products_by_permission($group)>
Returns a list of product objects for which the user has $group privileges
and which they can access.
$group must be one of the groups defined in PER_PRODUCT_PRIVILEGES.
=item C<can_see_user(user)>
Returns 1 if the specified user account exists and is visible to the user,
0 otherwise.
=item C<can_edit_product(prod_id)>
Determines if, given a product id, the user can edit bugs in this product
at all.
=item C<visible_bugs($bugs)>
Description: Determines if a list of bugs are visible to the user.
Params: C<$bugs> - An arrayref of Bugzilla::Bug objects or bug ids
Returns: An arrayref of the bug ids that the user can see
=item C<can_see_bug(bug_id)>
Determines if the user can see the specified bug.
=item C<can_see_product(product_name)>
Returns 1 if the user can access the specified product, and 0 if the user
should not be aware of the existence of the product.
=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<clear_product_cache>
Clears the stored values for L</get_selectable_products>,
L</get_enterable_products>, etc. so that their data will be read from
the database again. Used mostly by L<Bugzilla::Product>.
=item C<get_selectable_products>
Description: Returns all products the user is allowed to access. This list
is restricted to some given classification if $classification_id
is given.
Params: $classification_id - (optional) The ID of the classification
the products belong to.
Returns: An array of product objects, sorted by the product name.
=item C<get_selectable_classifications>
Description: Returns all classifications containing at least one product
the user is allowed to view.
Params: none
Returns: An array of Bugzilla::Classification objects, sorted by
the classification name.
=item C<can_enter_product($product_name, $warn)>
Description: Returns a product object if the user can enter bugs into the
specified product.
If the user cannot enter bugs into the product, the behavior of
this method depends on the value of $warn:
- if $warn is false (or not given), a 'false' value is returned;
- if $warn is true, an error is thrown.
Params: $product_name - a product name.
$warn - optional parameter, indicating whether an error
must be thrown if the user cannot enter bugs
into the specified product.
Returns: A product object if the user can enter bugs into the product,
0 if the user cannot enter bugs into the product and if $warn
is false (an error is thrown if $warn is true).
=item C<get_enterable_products>
Description: Returns an array of product objects into which the user is
allowed to enter bugs.
Params: none
Returns: an array of product objects.
=item C<can_access_product($product)>
Returns 1 if the user can search or enter bugs into the specified product
(either a L<Bugzilla::Product> or a product name), and 0 if the user should
not be aware of the existence of the product.
=item C<get_accessible_products>
Description: Returns an array of product objects the user can search
or enter bugs against.
Params: none
Returns: an array of product objects.
=item C<can_administer>
Returns 1 if the user can see the admin menu. Otherwise, returns 0
=item C<check_can_admin_product($product_name)>
Description: Checks whether the user is allowed to administrate the product.
Params: $product_name - a product name.
Returns: On success, a product object. On failure, an error is thrown.
=item C<check_can_admin_flagtype($flagtype_id)>
Description: Checks whether the user is allowed to edit properties of the flag type.
If the flag type is also used by some products for which the user
hasn't editcomponents privs, then the user is only allowed to edit
the inclusion and exclusion lists for products they can administrate.
Params: $flagtype_id - a flag type ID.
Returns: On success, a flag type object. On failure, an error is thrown.
In list context, a boolean indicating whether the user can edit
all properties of the flag type is also returned. The boolean
is false if the user can only edit the inclusion and exclusions
lists.
=item C<can_request_flag($flag_type)>
Description: Checks whether the user can request flags of the given type.
Params: $flag_type - a Bugzilla::FlagType object.
Returns: 1 if the user can request flags of the given type,
0 otherwise.
=item C<can_set_flag($flag_type)>
Description: Checks whether the user can set flags of the given type.
Params: $flag_type - a Bugzilla::FlagType object.
Returns: 1 if the user can set flags of the given type,
0 otherwise.
=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<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_inherited> as a string (a comma-separated
list).
=item C<product_responsibilities>
Retrieve user's product responsibilities as a list of component objects.
Each object is a component the user has a responsibility for.
=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 id, returns
C<0> otherwise.
=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.
=item C<is_insider>
Returns true if the user can access private comments and attachments,
i.e. if the 'insidergroup' parameter is set and the user belongs to this group.
=item C<is_global_watcher>
Returns true if the user is a global watcher,
i.e. if the 'globalwatchers' parameter contains the user.
=item C<can_tag_comments>
Returns true if the user can attach tags to comments.
i.e. if the 'comment_taggers_group' parameter is set and the user belongs to
this group.
=item C<last_visited>
Returns an arrayref L<Bugzilla::BugUserLastVisit> objects.
=item C<is_involved_in_bug($bug)>
Returns true if any of the following conditions are met, false otherwise.
=over
=item *
User is the assignee of the bug
=item *
User is the reporter of the bug
=item *
User is the QA contact of the bug (if Bugzilla is configured to use a QA
contact)
=item *
User is in the cc list for the bug.
=back
=item C<set_groups>
C<hash> These specify the groups that this user is directly a member of.
To set these, you should pass a hash as the value. The hash may contain
the following fields:
=over
=item C<add> An array of C<int>s or C<string>s. The group ids or group names
that the user should be added to.
=item C<remove> An array of C<int>s or C<string>s. The group ids or group names
that the user should be removed from.
=item C<set> An array of C<int>s or C<string>s. An exact set of group ids
and group names that the user should be a member of. NOTE: This does not
remove groups from the user where the person making the change does not
have the bless privilege for.
If you specify C<set>, then C<add> and C<remove> will be ignored. A group in
both the C<add> and C<remove> list will be added. Specifying a group that the
user making the change does not have bless rights will generate an error.
=back
=item C<set_bless_groups>
C<hash> - This is the same as set_groups, but affects what groups a user
has direct membership to bless that group. It takes the same inputs as
set_groups.
=back
=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<create>
The same as L<Bugzilla::Object/create>.
Params: login_name - B<Required> The login name for the new user.
realname - The full name for the new user.
cryptpassword - B<Required> The password for the new user.
Even though the name says "crypt", you should just specify
a plain-text password. If you specify '*', the user will not
be able to log in using DB authentication.
disabledtext - The disable-text for the new user. If given, the user
will be disabled, meaning they cannot log in. Defaults to an
empty string.
disable_mail - If 1, bug-related mail will not be sent to this user;
if 0, mail will be sent depending on the user's email preferences.
=item C<check>
Takes a username as its only argument. Throws an error if there is no
user with that username. Returns a C<Bugzilla::User> object.
=item C<check_account_creation_enabled>
Checks that users can create new user accounts, and throws an error
if user creation is disabled.
=item C<check_and_send_account_creation_confirmation($login)>
If the user request for a new account passes validation checks, an email
is sent to this user for confirmation. Otherwise an error is thrown
indicating why the request has been rejected.
=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, they
can change their username to $username. (That is, this function
will return a boolean true value).
=item C<login_to_id($login, $throw_error)>
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 returns 0.
However, if $throw_error is set, the function will throw a user error
instead of returning.
This function can also be used when you want to just find out the userid
of a user, but you don't want the full weight of Bugzilla::User.
However, consider using a Bugzilla::User object instead of this function
if you need more information about the user than just their ID.
=item C<validate_password($passwd1, $passwd2)>
Returns true if a password is valid (i.e. meets Bugzilla's
requirements for length and content), else throws an error.
Untaints C<$passwd1> if successful.
If a second password is passed in, this function also verifies that
the two passwords match.
=item C<validate_password_check($passwd1, $passwd2)>
This sub routine is similair to C<validate_password>, except that it allows
the calling code to handle its own errors.
Returns undef and untaints C<$passwd1> if a password is valid (i.e. meets
Bugzilla's requirements for length and content), else returns the error.
If a second password is passed in, this function also verifies that
the two passwords match.
=item C<match_field($data, $fields, $behavior)>
=over
=item B<Description>
Wrapper for the C<match()> function.
=item B<Params>
=over
=item C<$fields> - A hashref with field names as keys and a hash as values.
Each hash is of the form { 'type' => 'single|multi' }, which specifies
whether the field can take a single login name only or several.
=item C<$data> (optional) - A hashref with field names as keys and field values
as values. If undefined, C<Bugzilla-E<gt>input_params> is used.
=item C<$behavior> (optional) - If set to C<MATCH_SKIP_CONFIRM>, no confirmation
screen is displayed. In that case, the fields which don't match a unique user
are left undefined. If not set, a confirmation screen is displayed if at
least one field doesn't match any login name or match more than one.
=back
=item B<Returns>
If the third parameter is set to C<MATCH_SKIP_CONFIRM>, the function returns
either C<USER_MATCH_SUCCESS> if all fields can be set unambiguously,
C<USER_MATCH_FAILED> if at least one field doesn't match any user account,
or C<USER_MATCH_MULTIPLE> if some fields match more than one user account.
If the third parameter is not set, then if all fields could be set
unambiguously, nothing is returned, else a confirmation page is displayed.
=item B<Note>
This function must be called early in a script, before anything external
is done with the data.
