Version 1.8.1

2008-10-03

This release fixes a few small issues. See the change-log for details.

• Bug Fix: Fixed typo in classname, 'DuplucateKeyDatabaseException' is now 'DuplicateKeyDatabaseException'. (2008-09-30 - Adam Franco)

Version 1.8.0

2008-09-24

This release adds support for IP-range-based group membership, user-preference storage, and caching of group membership information.

New database tables must be installed for user-preferences.

• New feature: #2102311 Agent: Now supports IP-range-based group membership. (2008-09-24 - Adam Franco)

• Change: AuthZ2: IsAuthorizedCache now saves the current user's group ids for the session to avoid unneeded groups membership searching. This doesn't change execution time too much, but does cut out between 17 and 18 queries or statement executions per execution cycle. (2008-09-24 - Adam Franco)

Version 1.7.0

2008-08-27

This release adds the ability to pass session information in the URLs to select actions, enabling access to some actions by Flash and other clients that do not reliably support cookies for all access.

• New feature: #1820865 Harmoni now allows configuration of actions that allow the SESSION ID in URLs.
  
  If we are using an SID for an action configured to allow it in the url, the Set-Cookie header is overwritten with a bogus one to prevent session fixation. (2008-08-26 - Adam Franco)

Version 1.6.2

2008-08-25

This release makes a few improvements to the Request system. See the change log for details.

• Bug Fix: #2068136 Request: PathInfo URLs now do not include empty values as these will break the order of arguments on the receiver side since PHP converts double-slashes (//) to a single slash (/) in the PATH_INFO variable. (2008-08-22 - Adam Franco)
• Change: Request: UrlWriters now support moveValueToBeginning() method to re-order how parameters appear in the URLs. (2008-08-22 - Adam Franco)

Version 1.6.1

2008-08-14

Fixed a thumbnail generation bug.

• Bug Fix: ImageProcessor: Now uses the ImageMagick 'identify' command to determine if an image has one or more frames (such as a multi-page PDF). Only multi-framed images will have the first-frame identifier '[0]' used when generating thumbnails. (2008-08-14 - Adam Franco)

Version 1.6.0

2008-08-14

This release fixes a number of security issues.

Security issues fixed:

* Cross-Site Request Forgeries (CSRF) are now eliminated from data-modification actions. Read about CSRF at: http://shiflett.org/articles/cross-site-request-forgeries

* Harmoni can now be configured to use secure/http-only cookies.

* Admin actions are now restricted to prevent listing of users and ids in the system.

• New feature: #2040513 Security/Actions: Actions that involve data modification can now be configured to require per-usertokens in the request to prevent Cross-Site Request Forgeries.
  
  Actions can be added to the list by using $harmoni->ActionHandler->addRequestTokenRequiredActions().
  
  Once a module/action pair is added to the list, all URLs written to it will include the per-user token and that token will be checked before the action is allowed to execute. (2008-08-14 - Adam Franco)
  (reported by Josh Abraham of Rapid7, LLC.)
• Bug Fix: #2040501 Security: Harmoni now supports setting the session.cookie_secure and session.cookie_httponly parameters in the harmoni config. (2008-08-14 - Adam Franco)
  (reported by Josh Abraham of Rapid7, LLC.)

Version 1.5.0

2008-08-13

This release makes several improvements to the Authorization, Repository, and Request systems to support Segue 2. See the change log for details.

• New feature: #1820937 Request: RequestContext now has a new mkUrlWithBase() method that allows the specification of a base-url to be used instead of the MYURL constant. (2008-08-07 - Adam Franco)
• Change: Repository: HarmoniRepository's getAssetsByType() method now first loads nodes by type to prevent lookups on all nodes. Cuts Segue 'All Visible' portal page loading from 65 seconds to 10 seconds. (2008-08-11 - Adam Franco)
• Bug Fix: #2048119 AuthZ2: Session-caching of authorizations now works again. (2008-08-12 - Adam Franco)
  (reported by Gabe Schine)
• Change: AuthZ2: Authorization cache now expires after 10 minutes to prevent users with very old sessions from retaining abilities due to cached authorizations. (2008-08-12 - Adam Franco)

Version 1.4.7

2008-08-07

This release fixes an authorization issue as well as enhances security by preventing Javascript from being written to the logs. See the change log for details.

• Bug Fix: AuthZ2: A typo in the view authorization id was preventing cascading-up implicit view authorizations from ever being written. (2008-08-07 - Adam Franco)
  (reported by Peter Wilkins of MIT)
• Bug Fix: #2040255 Logging: Log messages are now filtered to prevent Javascript insertion. (2008-08-05 - Adam Franco)
  (reported by Josh Abraham of Rapid7, LLC.)
• Change: ErrorHandler: New NoMoreIteratorElementsException available.
  
  UnimplementedException now includes class and method name of the unimplemented method. (2008-08-04 - Adam Franco)

Version 1.4.6

2008-08-01

This release fixes a number of issues that were affecting Segue 2.

Most important is a fix to the image-processor to correctly support generation of thumbnails from multi-page PDF files.

• Bug Fix: #2031483 ImageProcessor: Thumbnail generation from multi-page PDFs now only extracts the first page enabling valid thumbnails to be generated and preventing extra processing of other pages that was being overwhelmed by very large PDFs. (2008-07-29 - Adam Franco)
  (reported by Tom Coppeto of OnTapSolutions/O.K.I.)
• Bug Fix: #2034986 Sets: Fixed up SQL keys to allow sets to contain an item several times at different positions as is allowed in the interface. (2008-08-01 - Adam Franco)
• Bug Fix: AuthZ2: Fixed up Hierarchy Exceptions to use valid Exception classes. (2008-07-25 - Adam Franco)

Version 1.4.5

2008-07-24

This release fixes a few minor issues that were causing problems with Segue.

• Bug Fix: #2021574 Request: PathInfoRequest handler now replaces encoded question marks "%3F" with a "_quest_" placeholder to get around an issue with Apache's mod_rewrite accidentally decoding encoded question marks in some situations. (2008-07-23 - Adam Franco)
• Bug Fix: GUI2: Now forces the empty namespace for the theme id parameter to prevent the CSS from breaking when namespaces are not closed. (2008-07-22 - Adam Franco)

Version 1.4.4

2008-07-21

This release fixes an issue with Authorization settings for members of groups the ids of which contain quotes.

• Bug Fix: #2023672 AuthZ/PDO: Adding temporary work-around for bug 2023672/ PHP bug 41125
  
  A PHP/PDO bug is resulting in problems when escaped quotes exist in an SQL string that is then prepared. This is occurring for users who are members of groups that have a quote in their LDAP DN.
  
  This is the second time this bug has bitten us, this time in the AuthZ2 AuthorizationCache. The first workaround was added to fix Harmoni bug 1970447.

  (reported by Hector Vila of Middlebury College)

Version 1.4.3

2008-07-17

This release fixes several issues with Themes and Logging.

• Bug Fix: #2018232 GUI2: Output handler now sends theme options in the theme CSS URL. (2008-07-17 - Adam Franco)
• Bug Fix: #2009090 Logging: Now returns an empty string if there is no backtrace. (2008-07-17 - Adam Franco)

Version 1.4.2

2008-07-11

This release includes a minor improvement to support Segue.

• Change: AuthZ2: More use of prepared statements in Authorization fetching methods to speed up Segue's 'roles' UI. (2008-07-11 - Adam Franco)

Version 1.4.1

2008-07-10

This release adds some minor improvements to support Segue.

• New feature: GUI2: GUIManager now can be configured to link to theme styles at a URL. (2008-06-18 - Adam Franco)
• Change: DatabaseManager: New NoSuchTableDatabaseException to classify missing table errors. Currently only supported by MySQL. (2008-07-08 - Adam Franco)
• Bug Fix: Agent: The Users group now includes all groups except itself and Everyone and all agents except Anonymous. This enables the Users group to be a stand-in for any user who has been authenticated. (2008-07-10 - Adam Franco)

Version 1.4.0

2008-06-16

This release includes two improvements:

* The ActionHandler now supports the specification of default parameters to be used when the default module and action are used.

* New methods for converting strings to UTF-8 and converting 'smart-quotes'. Usage of this new String->makeUtf8() method requires PHP to be compiled with the --enable-mbstring option.

• New feature: #1995141 ActionHandler/HarmoniConfig: Can now specify default parameters along with the default module and action. (2008-06-16 - Adam Franco)
• New feature: #1993889 Primitives: String and HtmlString now include a new method for converting non-UTF-8 characters to UTF-8: makeUtf8 (2008-06-16 - Adam Franco)

Version 1.3.5

2008-06-13

Harmoni versions 1.2.0 through 1.3.4 included a bug in AuthZ2 in which implicit authorizations were not created when new nodes were created with Hierarchy->createNode(). This release fixes that issue.

For other improvements please see the change-log.

• Bug Fix: #1991183 AuthZ2: Fixed AuthZ2 issue where implicit AZs were not being created for new nodes.
  
  This had the effect of causing Admins to not be authorized to view new Segue sites. Implicit AZs were created OK in other situations because nodes were attached to parents via the addParent() method which triggered implicit AZ insertion. (2008-06-12 - Adam Franco)
• Change: Request: Specifying null for a URL value will now remove the key rather than setting the value to an empty string. (2008-06-10 - Adam Franco)
• New feature: Logging: Can now return a list of existing categories. (2008-06-10 - Adam Franco)
• Change: AuthNMethods: Visitor registration system now logs registration and email confirmation steps. (2008-06-10 - Adam Franco)
• Change: AuthNMethods: Visitor registration email now informs the user that their username is their email address. (2008-06-10 - Adam Franco)
• Bug Fix: StatusStars: Now keeps the output buffers in the correct order. (2008-06-13 - Adam Franco)

Version 1.3.4

2008-06-09

This release adds support for a visitor registration authentication method.

• New feature: #1820894 AuthNMethods: New Visitor Authentication method that allows for visitor registration. (2008-06-05 - Adam Franco)

Version 1.3.3

2008-06-03

This release fixes a few issues that were affecting Concerto, most notably, several issues with safe-mode restrictions when creating or extracting tar archives.

Harmoni now includes a custom version of the Archive/Tar PEAR library with a fix for bug #14058 that prevents proper extraction of archives with Safe Mode on.

• Bug Fix: AuthZ: Fix to old authorization implementation that was causing function types to get messed up on installation of Concerto. (2008-06-02 - Adam Franco)
• Change: #1912944 Archiving: Harmoni now includes a custom version of Archive/Tar with a fix for bug #14058 that was preventing decompression of tar files that have a directory hierarchy when in PHP 5.2+ with Safe Mode on.
  
  http://pear.php.net/bugs/bug.php?id=14058 (2008-06-03 - Adam Franco)
• Change: Repository: Repository::getAssetsBySearch() now recognizes a null-type properties object. (2008-06-03 - Adam Franco)

Version 1.3.2

2008-05-23

This release fixes a few errors affected a few users, notably a work-around for a PHP/PDO bug that results in segmentation faults when escaped quotes exist in an SQLstring that is then prepared. This is occurring when checking authorization for users who are members of groups that have a quote in their LDAP DN.

• Bug Fix: #1970447 PDO: Adding temporary work-around for bug 1970447/ PHP bug 41125
  
  A PHP/PDO bug is resulting in problems when escaped quotes exist in an SQL string that is then prepared. This is occurring for users who are members of groups that have a quote in their LDAP DN.

• Bug Fix: Hierarchy: Fix to the older Hierarchy implementation to prevent errors when not using Harmoni_Db. (2008-05-22 - Adam Franco)

Version 1.3.1

2008-05-22

This release fixes a minor theming issue that was affecting the Polyphony log-browsing actions.

• Bug Fix: Gui2: Theme URLs now do not get messed up in names-spaced actions like log-browsing. (2008-05-21 - Adam Franco)

Version 1.3.0

2008-05-20

This release adds support for a new Theming system, Gui2. Gui2 simplifies the expectations of themes to allow a wider range of possible implementations and storage techniques.

As well, a number of minor bugs have been fixed.

• New feature: #1820834 Gui2: New Gui2 system re-envisions the way themes are defined and accessed. Rather than forcing themes to be concrete classes, a variety of theme sources can be defined that can each determine how their themes are stored and retrieved.
  
  Themes may have options for varying their color scheme or other attributes, but this is an optional level of compliance, not forced. Similarly, themes may optionally support modification. (2008-05-14 - Adam Franco)
• Change: Gui/Gui2: The EMPHASIZED_BLOCK has be deprecated and a SIDEBAR_BLOCK added to enable better syntactical alignment between usage and theme definition. (2008-05-20 - Adam Franco)
• New feature: Utilities/Filing: A simple Filing interface has been added to provide an abstraction on 'files'. These are currently used in the new Gui2 system to get and set Thumbnails and theme images. (2008-05-20 - Adam Franco)
• Change: AuthNMethods: HttpAuth-token collector now can accept a user-function array instead of just a string. (2008-05-13 - Adam Franco)
• Bug Fix: #1964729 Request: Multiple calls to startNamespace(null) were not filling the name-space stack with null name-spaces, so when endNamespace() was then called, extra non-null name-spaces were removed from the stack. (2008-05-20 - Adam Franco)
  (reported by Jeff Merriman of MIT)
• Change: Request: Replacing slashes in path-info URLs.
  
  Apache denies requests where the path-info includes %2F, the encoded version of the forward slash, /. This is done to aid the security of CGI scripts, but means that we can't pass encoded slashes in PATH_INFO parameters.
  
  This fix replaces slashes with the string, '_slash_', when writing the path info urls and reverses that replacement on read. (2008-05-13 - Adam Franco)
• Bug Fix: Primitives: Fixed static/non-static method access in Chronology. (2008-05-13 - Adam Franco)
• Bug Fix: Primitives: Adding in a pass by reference to fix an Chronology bug.
  
  The _normalize() method needed an array passed by reference to act on. In the PHP 5 migration the reference got deleted by accident, so the normalization wasn't being done. This had the effect of not rolling over days when adding durations that bumped a date and time over the length of a day. (2008-05-14 - Adam Franco)

Version 1.2.0

2008-05-05

This release includes a new implementation of the Authorization and Hierarchy services along side of the original implementations. This new 'AuthZ2' implementation stores hierarchy and authorization data in a set of tables with foreign-key constraints/triggers to manage the removal of authorizations when nodes in the hierarchy are dropped. As well, AuthZ2 stores implicit authorizations as rows in an implicit_azs table to allow simple lookups without the need of traversing the hierarchy at read-time. AuthZ2 enables Segue to run approximately 600% faster, with some operations seeing 2000% decreases in execution time.

Additional improvements in this release include more robust Harmoni_Db support, as well as fixes to Tagging, Language, and Database services.

• New feature: #1951075 AuthZ2: New Authorization/Hierarchy package stores implicit authorizations as rows in their own table so that they can be quickly read at the expense of a small increase in writing time and storage space.
  
  Either AuthZ2 or the original Authorization and Hierarchy implementations can be used by Harmoni applications as these implementations are independent of one another. A migration script for moving hierarchy and authorization information out of The original tables and into the AuthZ2 tables can be found at harmoni/core/oki2/AuthZ2/migration.php
  
  Please note that in AuthZ2 the 'edu.middlebury.authorization.view' function has the property of cascading up the hierarchy as well as down. This property is needed by our Segue and Concerto applications and the lack of it in the original implementations required the use of the isAuthorizedBelow() function. All other authorization functions cascade down only. (2008-04-24 - Adam Franco)
• New feature: AuthorizationManager: Now can be configured to use Harmoni_Db. (2008-04-18 - Adam Franco)
• Change: Authorization: Cleaned up query syntax to do use addWhereEqual(), addWhereLike(), etc methods rather than manually building WHERE strings. (2008-04-21 - Adam Franco)
• Bug Fix: Authorization: Now explicit AZs do not create identical duplicate implicit AZs when searching for AZs for any agent. (2008-04-24 - Adam Franco)
• Change: Authorization: Added AuthorizationManager::getIsAuthorizedCache() method to access the IsAuthorizedCache used by the current AuthorizationManager for queueing of qualifier-ids. This new method and its usage by the Repository and Authentication systems allows swapping of the Authorization-Hierarchy implementation. (2008-04-21 - Adam Franco)
• Change: Authorization/Hierarchy: Now relying on type-hinting for validation of object parameters rather than using the ArgumentValidator. (2008-04-21 - Adam Franco)
• Change: Hierarchy: Cleaned up query syntax to do use addWhereEqual(), addWhereLike(), etc methods rather than manually building WHERE strings. (2008-04-21 - Adam Franco)
• New feature: IdManager: Now can be configured to use Harmoni_Db. (2008-04-18 - Adam Franco)
• Bug Fix: Harmoni_Db: Insert now ensures that at least one row of values exists. (2008-04-18 - Adam Franco)
• Bug Fix: Harmoni_Db: Can now set Auto-Increment table/key for retrieving the last insert id from INSERT query executions. (2008-04-24 - Adam Franco)
• Bug Fix: Harmoni_Db: Backtrace collection now works when preparing queries directly as well as from query-building objects. (2008-04-25 - Adam Franco)
• Change: Harmoni_Db: It seems that only the MySQL PDO adapter supports buffered queries, so result buffering is now done in PHP in Harmoni_Db rather than in the adapter. Hopefully performance won't take too much of a hit and portability will be preserved. (2008-04-29 - Adam Franco)
• Bug Fix: Harmoni_Db: New Harmoni_Db query result class for INSERT, UPDATE, and DELETE queries.

• *** IMPORTANT ***Change: Hierarchy: The node relation and ancestry tables, j_node_node and node_ancestry were both missing a reference to the hierarchy for which the node id was valid. This could cause conflicts if node ids are repeated in separate hierarchies. Existing Harmoni databases will need to have these columns added and the data updated. (2007-09-13 - Adam Franco)
• *** IMPORTANT ***Change: Scheduling: Two sc_item columns "start" and "end" conflict with reserved words in PostgreSQL. Existing Harmoni databases will need to have these columns added and the data updated. (2007-09-13 - Adam Franco)

  (function )&|(=\s?)&([^a-z#])|([^&])&\s?(\$)
  
  replaced with
  
  \1\2\3\4\5
  
  
  
  Special Changes were made to the following files to fix problems introduced in the search and replace for ampersands:
  
  polyphony/main/library/ResultPrinter/ArrayResultPrinter.class.php - getLayout()
  
  - $item = $this->_array[key($this->_array)];
  
  ======
  
  + $item = current($this->_array);
  
  harmoni/core/oki2/repository/HarmoniRecord.class.php - getParts()
  
  * Moved the following line out of the if-statement:
  
  * $activeValue = $allRecordFieldValues[$key]->getActiveVersion();
  
  harmoni/core/oki2/hierarchy/tree/Tree.class.php - _traverse()
  
  * Kept the first parameter being passed by reference. Needed in this case. (Adam Franco)

• Bug Fix: Repaired many PHP notices. (Gabe Schine)
• Bug Fix: Repaired many PHP notices. (Niraj Dhungel)
• Bug Fix: The hierarchy cache had a problem where _isCached() was called as a property instead of a method, square brackets [] versus parenthesis (), and was breaking the cache by creating nodes that were listed as children of other nodes, but did not have their parents listed. (Adam Franco)

  Records no longer have an active state. They either exist or they don't.
  
  Fields that are deleted now are actually removed from the DB if the Record is not version controlled.
  
  getIndices() now returns only the active indices per default, including inactive ones only if requested. (Gabe Schine)
• New feature: Added a free() call to the SelectQueryResult classes to free memory used by the select query. (Gabe Schine)
• New feature: Added the chronology library, a PHP implementation of the Squeak (Smalltalk) Kernel-Chronology package and aims to serve as a general PHP class-library for handling, comparing, and operating on chronological objects. The original Smalltalk implementation is licensed under the Squeak License http://squeak.org/download/license.html.
  
  This library includes classes that represent instants in time (DateAndTime, TimeStamp), lengths of time (Duration), spans of time anchored at certain instants (Timespan, Year, Month, Week, Date), as well as recurring instants across a span of time (Schedule).
  
  This library has been designed to support all possible dates, times, and durations, not just those since the UNIX epoch (1970). dates can have positive years (C.E./A.D.) or negative years (B.C.E./B.C.) and Durations have been tested to support lengths of time up to +/- 4 billion years with second-precision. Beyond 4 billion years to the limit of testing (50 billion years) Durations have hour-precision. (Adam Franco)
• New feature: Added URL-writing functionality as well as centralized processing of request-related variables from/to the browser into a family of classes related to the RequestHandler.
  
  All 'communication' between the browser and the program is now abstracted and can be subsequently changed transparently. (Gabe Schine)
• Change: In order to allow for globally unique ids from the IdManager, the IdManager now allows for an Id prefix to place on ids. The prefix 'id.middlebury.edu-' would lead to ids similar to 'id.middlebury.edu-1234567890'. This will allow for multiple IdManagers to be used together without each giving out the same Id strings. (Adam Franco)
• Change: In conjunction with the IdManager's added 'prefix' capabilities, the Harmoni SQL table definitions have been updated to support the storing of string Ids (currently up to 75 characters) that may have originated from the IdManager. Ids generated internally by the database remain as integers. (Adam Franco)
• Change: In conjunction with the IdManager's added 'prefix' capabilities, the Harmoni services that store Ids have been upgraded to allow string ids as well as integer ids. (Adam Franco)

• Change: DBHandler now provides methods for transaction handling. Applications can be coded to use transactions to ensure atomic writes. Databases that do not support transactions will simply ignore the calls. Nested transaction calls in MySQL are interpreted so that only the outer transaction is run allowing applications coded to use nested transactions to often operate on MySQL 4.0.11+. (Adam Franco)
• New feature: Now includes implementations of v2.0 of the O.K.I OSIDs. (Adam Franco)
• New feature: Now includes v2.0 of the O.K.I OSIDs. (Adam Franco)

• Change: DataManager: deleting a value from a Record without version control now actually deletes the value instead of flagging it as inactive. (Gabe Schine)
• Change: The LanguageLocalizer now defines functions for _() and gettext() that simply return the passed string, so that localized apps can fail gracefully to their native language if gettext is not installed. (Adam Franco)
• Change: DBHandler improvements: SQL strings are prettier now. Also added variable binding functionality. (Dobo Radichkov)

Version 0.2.0

2004-10-26

• New feature: Added a "MIME" service for sniffing mime types from file extensions. (Adam Franco)
• New feature: Added an ImageProcessor service for the resizing of images, generation of thumbnails, and other common image processing functions. This service can be configured to use multiple modules to handle different file types, as available. An example would be using PHP's GD libraries for handling jpegs and pngs, while using ImageMagick (via shell_exec()) for tiff, psd, pdf, etc. files. (Adam Franco)

• Change: Themes and layouts have been completely re-worked to support easier use and more user control of the themes. (Adam Franco)
• Change: Argument Validator now doesn't fail on string representations of integers; i.e. "100" as well as 100 will validate. (Adam Franco)
• New feature: Implemented the Digital Repository OSID in Harmoni. The DR uses the Hierarchy OSID, the DataManager, and the Shared OSID to provide for high-level access and browsing of Assets and their associated data/metadata. (Adam Franco)
• Change: Services: The Harmoni Services now check for the Error Handler and use that to print out errors if it is available. This makes for easier to read backtraces. (Adam Franco)
• Change: DBHandler: DBHandler now throws fatal errors with an explanation when a query fails. (Adam Franco)
• New feature: Hierarchy: Implemented the Hierarchy OSID. The Hierarchy supports the storing of multiple hierarchies and their nodes in one database. In the current implementation, the entire hierarchy is pulled from the database each load. This needs to be re-written to optimize it for fast reads from 100,000+ node hierarchy (current Segue at Middlebury has ~50,000 nodes). (Adam Franco)
• New feature: DataManager: added DataSet caching to the DataSetManager. Added support for required fields in DataSetTypeDefinitions. (Gabe Schine)
• Change: Removed argument validation from DateTime constructor to speed up code by 33%. (Gabe Schine)
• Change: DataManager: sped up fetching large numbers of DataSets at once (by a factor of two). (Gabe Schine)
• Change: DataManager: DataSet::prune() now takes a required VersionConstraint object on which to base the pruning process. Handling of pruning Tags is very very messy, but it works. (Gabe Schine)
• New feature: DataManager: can use DataSetManager::selectIDsBySearch() to search all/some DataSets and return a list of DataSets that match the criteria. (Gabe Schine)
• Change: DataManager: ValueVersion::prune() now deletes itself if the DataSet it is part of is inactive. (Gabe Schine)
• Change: DataManager: DataSet::prune() now removes all Tags associated with itself. (Gabe Schine)

Version 0.0.5

2004-01-09

• Change: Implementation of the OKI SharedManager (HarmoniSharedManager) now uses the HarmoniDataManager's IDManager for ID creation.

• Change: Harmoni::getData has been deprecated and replaced by Harmoni::getAttachedData to avoid ambiguity. (Gabe Schine)
• Change: IDManager::newID() now uses auto_increment DB functionality to reduce query count on compatible servers. (Gabe Schine)
• Bug Fix: DataSet::populate() now sets its own ID to avoid super re-duplication of DataSets in database. (Gabe Schine)
• Bug Fix: DateTime::now() now gives correct Hour value. Likewise MySQLDatabase::toDBDate() now adds 1 to hour value to give correct 1-24 value. Other DB Types haven't yet been checked. (Gabe Schine)
• Change: Modified field in HarmoniDataManager table "datasetfield" from "datasetfield_created" to "datasetfield_modified" since it is updated on every commit(). (Gabe Schine)
• New feature: Extensive work on DataManager. Now works for creating/retrieving datasets with version controls. (Gabe Schine)
• Bug Fix: Corrected ArgumentValidator call in DBHandler checking for DateTimeInterface instead of DateTime. (Gabe Schine)
• New feature: Added AgentInformationHandler::agentExists($name, [$method]) which steps through each AuthenticationMethod and checks for an existing agent. (Gabe Schine)
• Change: LoginState now has better support for Active/Authenticated agents. It should allow one to change the active agent without disturbing the actual authentication process. (Gabe Schine)

Version 0.0.4

2003-12-06

• New feature: DateTime class has two new functions: toString() and toMDY() which display a full date/time and a MM/DD/YY string, respectfully. (Gabe Schine)
• New feature: Harmoni::pathInfoParts now contains an array of PATH_INFO elements. (Gabe Schine)
• New feature: ErrorHandler has new method getErrorQueue() which returns the error queue in a Queue object. (Gabe Schine)

• Change: Context object now carries an array holding the executed actions path, available by referencing Context::actionPath. (Gabe Schine)
• Change: ActionHander and Harmoni: ActionHandler now only passes a reference to the Harmoni object to action functions and scripts. Other variables are available here: Harmoni::HTTPVars, Harmoni::Context, Harmoni::LoginState. (Gabe Schine)
• Change: Removed many .interface.php files to save on load times and unnecessary flexibility. (Gabe Schine)
• Change: LoginHandler no longer throws a default error on login failure. LoginHandler::setFailedLoginError() can be used to specify an error to be thrown to the UserError service. This change is primarily so that people using different languages won't be locked into using English for this error message (a pretty important one). (Gabe Schine)
• Change: LoginState::attachData() has been moved to Harmoni::attachContextData() and LoginState::getData() has been moved to Context::getData() for logical and organizational reasons. (Gabe Schine)
• Change: LoginHandler and Harmoni: when LoginHandler is used, the action that is checked for required authentication is now the LAST action executed instead of the first. This way, the action that finally ends up being executed is the "authoritative" action. (Gabe Schine)
