UserService

com.atlassian.stash.user.UserService

Class Overview

Provides methods for querying users and managing authentication. This service also offers limited ability to update the current user.

A note about user stores and deleted users: the system uses Crowd to provide access to LDAP servers, other Crowd servers, or JIRA (which is able to serve as a central user store for other Atlassian products). Crowd maintains a local cache of users, which is termed the "user store" by this service. The system also maintains a secondary table of users, outside Crowd, allowing it to decorate Crowd users with additional properties as well as to anchor relationships between users and their data, such as comments and pull requests.

Because the Crowd user store is a cache of users managed elsewhere, be they in LDAP, JIRA, etc., it is possible for users to be deleted from that user store but still exist in the system's secondary user table. Such users are termed "deleted", and, when retrieved, will only offer a minimal set of data. Generally, after deletion, only a user's username is still available. Display names, e-mail addresses and other data are managed by Crowd and are lost when the user is deleted.

In addition to deleted users, Crowd has the concept of an inactive user. These users cannot log into Stash and may or may not have an associated StashUser. Inactive users are handled consistently as deleted and both are taken into consideration when determining isActive().

Delete the avatar associated with a user.

This will revert the avatar of the user in the UI to his/her Gravatar image (if the Gravatar integration is enabled) or to the default user avatar (if the Gravatar integration is disabled)

Parameters
user the user whose (local) avatar will be removed

public boolean existsGroup (String groupName)

Retrieves a flag indicating whether the specified group exists.

Parameters
groupName the group name
Returns
  • true if a group with the specified name exists in any directory; otherwise, false

@Nonnull public Page<String> findGroups (PageRequest pageRequest)

Retrieves a page of groups.

Note: To filter the retrieved groups by name, use findGroupsByName(String, PageRequest) instead.

Parameters
pageRequest defines the page of groups to retrieve
Returns
  • the requested page of groups, which may be empty but never null
See Also

@Nonnull public Page<String> findGroupsByName (String groupName, PageRequest pageRequest)

Retrieves a page of groups, optionally filtering the returned results to those containing the specified groupName. If the provided groupName is null, this method behaves identically to findGroups(PageRequest).

Parameters
groupName 0 or more characters to apply as a filter on returned groups
pageRequest defines the page of groups to retrieve
Returns
  • the requested page of groups, potentially filtered, which may be empty but never null
See Also

@Nonnull public Page<String> findGroupsByPrefix (String groupPrefix, PageRequest pageRequest)

Retrieves a page of groups, optionally filtering the returned results to those beginning with the specified groupPrefix. If the provided groupPrefix is null, this method behaves identically to findGroups(PageRequest).

This method varies slightly from findGroupsByName(String, PageRequest), which will match the specified name at the beginning of any word boundary in the group. For example, "test-group" will match "group". With this method, a prefix of "group" will not match "test-group".

Parameters
groupPrefix 0 or more characters defining a prefix which returned group names must start with
pageRequest defines the page of groups to retrieve
Returns
  • the requested page of groups, potentially filtered by prefix, which may be empty but never null
See Also

See Also

@Nullable public StashUser findUserByNameOrEmail (String value)

Retrieve the first active normal user whose username or e-mail address exactly matches the provided value.

Returns
  • a user whose username or e-mail address matches the specified value, or null if no matching user was found

@Nonnull public Page<? extends StashUser> findUsers (PageRequest pageRequest)

Returns
  • the requested page of users, potentially filtered, which may be empty but never null

@Nonnull public CacheableAvatarSupplier getAvatar (StashUser user, int size)

Retrieves the current avatar for the specified user at a requested size. Avatars are square, so the size provided here is used as both height and width for the avatar.

The requested size will be normalised to fall within a well-defined set sizes. The supported sizes are:

  • 256
  • 128
  • 96
  • 64
  • 48
Any size larger than 256 will be normalised down to 256, and any size smaller than 48 will be normalised up to 48. Otherwise, sizes are normalised to the next size up, where they don't match exactly: 56 will be normalised to 64, 100 will be normalised to 128, and so on.

user the user whose avatar should be retrieved
size the desired height and width for the avatar
Returns
  • a supplier which can be used to access the requested avatar
