# NAME

Bugzilla::User - Object for a Bugzilla user

# 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});

# 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 Bugzilla->user.

`Bugzilla::User` is an implementation of Bugzilla::Object, and thus provides all the methods of Bugzilla::Object in addition to the methods listed below.

# CONSTANTS

`USER_MATCH_MULTIPLE`

  Returned by `match_field()` when at least one field matched more than one user, but no matches failed.

`USER_MATCH_FAILED`

  Returned by `match_field()` when at least one field failed to match anything.

`USER_MATCH_SUCCESS`

  Returned by `match_field()` when all fields successfully matched only one user.

`MATCH_SKIP_CONFIRM`

  Passed in to match_field to tell match_field to never display a confirmation screen.

# METHODS

## Saved and Shared Queries

`queries`

  Returns an arrayref of the user's own saved queries, sorted by name. The array contains Bugzilla::Search::Saved objects.

`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 Bugzilla::Search::Saved objects.

`queries_available`

  Returns an arrayref of all queries to which the user could possibly subscribe. This includes the contents of "queries_subscribed". An array of Bugzilla::Search::Saved objects.

`flush_queries_cache`

  Some code modifies the set of stored queries. Because `Bugzilla::User` does not handle these modifications, but does cache the result of calling `queries` internally, such code must call this method to flush the cached result.

`queryshare_groups`

  An arrayref of group ids. The user can share their own queries with these groups.

## Other Methods

`id`

  Returns the userid for this user.

`login`

  Returns the login name for this user.

`email`

  Returns the user's email address. Currently this is the same value as the login.

`name`

  Returns the 'real' name for this user, if any.

`showmybugslink`

  Returns `1` if the user has set his preference to show the 'My Bugs' link in the page footer, and `0` otherwise.

`identity`

  Returns a string for the identity of the user. This will be of the form `name <email>` if the user has specified a name, and `email` otherwise.

`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.

`authorizer`

  This is the 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.

`set_authorizer($authorizer)`

  Sets the Bugzilla::Auth object to be returned by `authorizer()`. Should only be called by `Bugzilla::Auth::login`, for the most part.

`disabledtext`

  Returns the disable text of the user, if any.

`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.

`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 `values(%{$user->groups})`.)

`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.

`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.

`in_group_id`

  Determines whether or not a user is in the given group by id.

`bless_groups`

  Returns an arrayref of hashes of `groups` entries, where the keys of each hash are the names of `id`, `name` and `description` columns of the `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.

`get_products_by_permission($group)`

  Returns a list of product objects for which the user has $group privileges and which he can access. $group must be one of the groups defined in PER_PRODUCT_PRIVILEGES.

`can_see_user(user)`

  Returns 1 if the specified user account exists and is visible to the user, 0 otherwise.

`can_edit_product(prod_id)`

  Determines if, given a product id, the user can edit bugs in this product at all.

`can_see_bug(bug_id)`

  Determines if the user can see the specified bug.

`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.

`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.

`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.

`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.

`can_enter_product($product_name, $warn)`

       Description: Returns 1 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:     1 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).

`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.

`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.

`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.

`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.

`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.

`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.

`direct_group_membership`

  Returns a reference to an array of group objects. Groups the user belong to by group inheritance are excluded from the list.

`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.

`visible_groups_direct`

  Returns a list of groups that the user is aware of.

`visible_groups_as_string`

  Returns the result of `visible_groups_inherited` as a string (a comma-separated list).

`product_responsibilities`

  Retrieve user's product responsibilities as a list of component objects. Each object is a component the user has a responsibility for.

`can_bless`

  When called with no arguments: Returns `1` if the user can bless at least one group, returns `0` otherwise.

  When called with one argument: Returns `1` if the user can bless the group with that id, returns `0` otherwise.

`wants_bug_mail`

  Returns true if the user wants mail for a given bug change.

`wants_mail`

  Returns true if the user wants mail for a given set of events. This method is more general than `wants_bug_mail`, allowing you to check e.g. permissions for flag mail.

`is_mover`

  Returns true if the user is in the list of users allowed to move bugs to another database. Note that this method doesn't check whether bug moving is enabled.

`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.

`is_global_watcher`

  Returns true if the user is a global watcher, i.e. if the 'globalwatchers' parameter contains the user.

# CLASS FUNCTIONS

These are functions that are not called on a User object, but instead are called "statically," just like a normal procedural function.

`create`

  The same as "create" in Bugzilla::Object.

  Params: login_name - Required The login name for the new user. realname - The full name for the new user. cryptpassword - 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 he 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.

`check`

  Takes a username as its only argument. Throws an error if there is no user with that username. Returns a `Bugzilla::User` object.

`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).

`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.

`user_id_to_login($user_id)`

  Returns the login name of the user account for the given user ID. If no valid user ID is given or the user has no entry in the profiles table, we return an empty string.

`validate_password($passwd1, $passwd2)`

  Returns true if a password is valid (i.e. meets Bugzilla's requirements for length and content), else returns false. Untaints `$passwd1` if successful.

  If a second password is passed in, this function also verifies that the two passwords match.
