Release Date

Grouper v1.2.0



Changes:

  • UI NEW: Sorted lists of groups, stems and subjects when browsing or searching.
  • UI NEW: Advanced stem search allows finer control of searching.
  • UI NEW: Import and export of membership lists from / to simple delimited text files, i.e., comma or tab separated.
  • UI CHANGE: Possible to configure default attributes to use for displaying groups, stems and subjects (configured by source.)
  • UI CHANGE: Advanced groups search now includes ability to search by group type.
  • UI CHANGE: Support display of multi-values in subject summary view. This ought to work - but so far we have not had any to play with...
  • UI CHANGE: HTML forms now use the POST method.
  • API NEW: added GrouperQuery support for selecting groups by their Type.
  • API NEW: Operational attributes (createTime, creator) are now maintained for Memberships as they have been for Groups and Stems, in preparation for future support of aging of Memberships.
  • API NEW: Stems can be renamed.
  • API NEW: A prototype extension framework to ease integration of code external to the core API by defining a common build process and means of referring to the Grouper installation.
  • API NEW: Updated Subject API from v0.2.1 to v0.3.0rc1-cvs to take advantage of security and performance improvements. Note that existing JDBCSourceAdapter configuration must change somewhat.
  • API NEW: An experimental DAO layer has been introduced to separate business logic from persistence logic.
  • API NEW: The default privilege caching TTL has been changed.
  • API NEW: GrouperShell updated to v0.1.1.
  • API NEW: Example code to bootstrap a wheel group ("ant eg.bootstrap").
  • API BUGFIX: Operational attributes (createTime, creator) of groups whose memberships were indirectly modified are now updated.
  • API BUGFIX: The build process now honors any pre-existing CLASSPATH.
  • API BUGFIX: Added "membership_uuid_idx" index to "grouper_memberships" table.
  • API BUGFIX: Updated "conf/ehcache.xml" to no longer overflow to disk by default.
  • API BUGFIX: Fixed two severe membership calculation bugs (jira#1, jira#2).
  • API BUGFIX: Fixed bugs where imported Groups and Stems were not assigned UUIDs.
  • API BUGFIX: Fixed some XML escaping issues.
  • API BUGFIX: API BUGFIX:"ant test" now has a proper dependency chain and can be called without having previously initialized the database.
  • API BUGFIX: Added indices "grouper_groups.parent_stem" and "grouper_stems.parent_stem" to address performance issues.
  • API CAVEAT: The native relational schema underlying Grouper v1.2.0 has been changed since v1.1.

Grouper v0.9


    Changes:* NEW: New public API.* NEW: New query API. This includes the ability for sites to create their own custom query filters for use within the query API.

  • NEW: New access and naming adapter APIs and interfaces.
  • NEW: "all" subject that can be assigned memberships and granted privileges that maps to all subjects that are identifiable by Grouper's Subject API configuration.
  • NEW: Event logging
  • NEW: Configuration options for controlling what privileges, if any, are granted to the "all" subject whenever a new group or stem is created. By default, READ and VIEW are granted to "all" upon group creation and no privileges are granted to "all" upon stem creation.
  • NEW: Subject IDs associated with Member objects within the Groups Registry can now be changed with the Member.setSubjectId() method.
  • NEW: Internal source adapter for resolving the "root" (GrouperSystem) and "all" (GrouperAll) subjects. No configuration is necessary to use this adapter within Grouper.
  • NEW: Experimental wheel-group support. This is disabled by default. If enabled, all members of the group are treated as root-like subjects with all access and naming privileges.
  • UPDATE: New internals.
  • UPDATE: ehcache-based caches for access and naming privilege resolution.
  • UPDATE: Grouper source adapter no longer needs to be configured within conf/sources.xml.
