-oauth2-php revision 23, 2011-01-25 ----------------------- -* introduce Drupal style getVariable() and setVariable, replace legacy - variable get/set functions. -* remove hardcode PHP display_error and errror_reporting, as this should - be manually implement within 3rd party integration. -* make verbose error as configurable and default disable, as this should - be manually enable within 3rd party integration. -* add lib/OAuth2Client.inc and lib/OAuth2Exception.inc for client-side - implementation. - -oauth2-php revision 21, 2010-12-18 ----------------------- -* cleanup tabs and trailing whitespace at the end. -* remove server/examples/mongo/lib/oauth.php and - server/examples/pdo/lib/oauth.php, so only keep single copy as - lib /oauth.php. -* issue #5: Wrong variable name in get_access_token() in pdo_oatuh.php. -* issue #6: mysql_create_tables.sql should allow scope to be NULL. -* issue #7: authorize_client_response_type() is never used. -* issue #9: Change "redirect_uri" filtering from FILTER_VALIDATE_URL to - FILTER_SANITIZE_URL. -* better coding syntax for error() and callback_error(). -* better pdo_oauth2.php variable naming with change to - mysql_create_tables.sql. -* change REGEX_CLIENT_ID as 3-32 characters long, so will work with md5() - result directly. -* debug linkage to oauth2.php during previous commit. -* debug redirect_uri check for AUTH_CODE_GRANT_TYPE, clone from - get_authorize_params(). -* update mysql_create_tables.sql with phpmyadmin export format. -* rename library files, prepare for adding client-side implementation. -* code cleanup with indent and spacing. -* code cleanup true/false/null with TRUE/FALSE/NULL. -* rename constants with OAUTH2_ prefix, prevent 3rd party integration - conflict. -* remove HTTP 400 response constant, as useless refer to draft v10. -* merge ERROR_INVALID_CLIENT_ID and ERROR_UNAUTHORIZED_CLIENT as - OAUTH2_ERROR_INVALID_CLIENT, as refer to that of draft v9 to v10 changes. -* improve constants comment with doxygen syntax. -* update class function call naming. -* coding style clean up. -* update part of documents. -* change expirseRefreshToken() as unsetRefreshToken(). -* update token and auth code generation as md5() result, simpler for manual -

-oauth2-php revision 9, 2010-09-04 ----------------------- -- fixes for issues #2 and #4, updates oauth lib in the example folders to - the latest version in the 'lib' folder. -- updates server library to revision 10 of the OAuth 2.0 spec. -- adds an option for more verbose error messages to be returned in the JSON - response. -- adds method to be overridden for expiring used refresh tokens. -- fixes bug checking token expiration. -- makes some more methods protected instead of private so they can be - overridden. -- fixes issue #1 http://code.google.com/p/oauth2-php/issues/detail?id=1 - -oauth2-php revision 7, 2010-06-29 ----------------------- -- fixed mongo connection constants. -- updated store_refresh_token to include expires time. -- changed example server directory structure -- corrected "false" return result on get_stored_auth_code. -- implemented PDO example adapter. -- corrected an error in assertion grant type. -- updated for ietf draft v9: -
