+IBX Change Log  version           (2.3-0) Tue, 03 Apr 2018 11:48:08 +0100
-+
-+
+IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
-+
+all previous copies of the IBX source code tree before installing this release.
-+
-+
+The IBX packages used by most users have not changed, with one exception. The
-+
+IBServices unit has been moved to the package iblegacyServices.lpk. To continue
-+
+to use the IBServices unit in your applications, please add the iblegacyServices
-+
+to the list of dependencies. To do this, open the Project Inspector and select
-+
+Add->New Requirement and select "ibLegacyServices" from the list of available
-+
+packages.
-+
-+
+. New unit IBXServices. The IBXServices unit is a re-architectured update of
-+
+   the IBServices unit providing what is intended to be a clearer and easier to
-+
+   use set of IB Services components. See Chapter 10 of the IBX User Guide for
-+
+   more information and the guide to "Firebird Service Management Using IBX".
-+
+   As indicated above, the legacy services components are still available and
-+
+   provided in a separate package. There is no need to update working applications
-+
+   using the older versions except for an additional package dependency.
-+
-+
+. The IBX packages and source code tree have been re-organised in an attempt to
-+
+   finally get rid of the "duplicate ppu" warnings. This re-organisation should
-+
+   not affect existing users. Section 2.3 of the IBX User Guide describes the
-+
+   new set of IBX packages.
-+
-+
+. The ibx/examples/DBAdmin and the ibx/examples/services example have been
-+
+   updated to use the new Services API components.
-+
-+
+. The iblocal package has been updated to use the new Services API components.
-+
-+
+. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
-+
+   TIBXSecurityService. It had been wrongly classified in the previous version
-+
+   as a per database configuration item. It is global to a server and hence
-+
+   correctly positioned as part of the Security Package. In the DBAdmin example,
-+
+   the setting has moved to the mappings page.
-+
-+
+. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
-+
+   are ignored.
-+
-+
+. TIBDatabase: DropDatabase now ensures that all transactions have been properly
-+
+   closed before the database is dropped. Before and After Disconnect event handlers
-+
+   are also fired.
-+
-+
+. TIBTransaction: OnStartTransaction event now fires every time the transaction
-+
+   is started and not just the first time.
-+
-+
+. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
-+
+   depenendency with comp type.
-+
-+
+. IBDataOutput: select query data output is now sent to stdout instead of stderr.
-+
-+
+. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
-+
+    then this is recognised and not ignored.
-+
-+
+. TIBDataSet, TIBQuery, TIBTable: additions:
-+
+    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
-+
+    function GetPerfStatistics(var stats: TPerfCounters): boolean;
-+
+    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
-+
-+
+    GetRowsAffected returns the affected row counts from the last insert/update/delete
-+
+    if EnableStatistics = true then GetPerfStatistics returns the current stats
-+
+    counters for the select query. Note: stats accumulate after each fetch from
-+
+    the database. To get total query cost after open, call the "Last" method
-+
+    and then GetPerfStatistics.
-+
-+
+    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
-+
-+
+. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
-+
+    in parenthesises.
-+
-+
+. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
-+
+    SQL identifiers are always delimited by double quotes. If false, then they are
-+
+    only delimited if the identifier is a reserved word, contains lower case or special
-+
+    characters. Set this property to true to retain previous behaviour.
-+
-+
+. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
-+
+    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
-+
-+
+. TIBDataSet, TIBQuery, TIBTable: addition:
-+
+       property MasterDetailDelay: integer {defaults to zero}
-+
-+
+    When non-zero and the dataset is a detail table referencing a master table
-+
+    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
-+
+    then a synchronisation delay is added (in milliseconds) between the master
-+
+    row changing and the detail dataset being re-opened. If the master dataset
-+
+    is scrolled before the delay expires then the delay is reset. This can be used
-+
+    to avoid performance overheads when scrolling through a large master dataset.
-+
-+
+    Note: uses fptimer and hence requires a thread manager. Under Linux the
-+
+    chreads unit must be included in your project. TTimer is not used in order
-+
+    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
-+
-+
+. TIBExtract: User role grants now excluded when etGrantsToUser not specified
-+
+    with Extract Option eoDatabase.
-+
-+
+. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
-+
+    When a deLayoutChanged event is reported on the ListSource dataset, the
-+
+    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
-+
+    relationship with the control's datasource (master).
-+
-+
+. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
-+
-+
+. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
-+
+    stubs. Pedantic fix really, as procedures output in dependency order anyway.
-+
-+
+. TIBExtract: Package Headers and Package Bodies are now included in the extracted
-+
+    DDL (Firebird 3 and later only).
-+
-+
+. TIBLookupComboBox Autocomplete Fixes:
-+
+    i. Only appended text is now selected after autocomplete.
-+
+    ii. Uppercase keys no longer ignored for autocomplete.
-+
+    iii. Retain Prefix case is now honoured correctly.
-+
+    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
-+
+        before autocomplete performed. i.e. behaviour now the same as when
-+
+        no DataSource assigned.
-+
-+
+. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
-+
+    between SQL statements.
-+
-+
+. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
-+
+    ObjectNames are converted to upper case before matching against metadata object
-+
+    names, unless the objectname is delimited by double quotes, in which case, the
-+
+    double quotes are removed and the remaining string is used (unmodified) to match
-+
+    against the metadata object name.
-+
-+
+    If true then the ObjectName is used as is without modification and matched
-+
+    against the metadata object name. No attempt is made to remove double quotes.
-+
-+
+. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
-+
+    with eoTrigger, these extract types can be used to select only Database Triggers,
-+
+    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
-+
-+
+IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
-+
-+
+NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
-+
+AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
-+
+RELEASE.
-+
-+
+NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
-+
-+
+. IBExtract: Identity columns - add additional check for null column for generator name.
-+
-+
+. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
-+
+   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
-+
+   information). However, this is also a very useful mechanism for returning updated computed by
-+
+   column values. Values returned as a result of executing an Insert or Update statement
-+
+   replace existing values in the current row for each corresponding column.
-+
-+
+   Previously, if a dataset's select query included read only (computed by) fields then
-+
+   an automatic row refresh was performed after an insert or update query had been processed,
-+
+   irrespective of the setting of the "ForcedUpdates" property. This has changed such
-+
+   that an automatic refresh is no longer performed if an insert or update query contains
-+
+   a returning clause that updates one or more fields on the current row. A full row
-+
+   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
-+
+   field values and the select query contains read only fields. Use of Insert/update
-+
+   returning should be significantly more efficient than executing a refresh query.
-+
-+
+   This behaviour change is intended to be backwards compatible and there should be no need to change
-+
+   existing programs, other than to improve performance by using the new capability.
-+
-+
+. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
-+
+   they are called when the dataset row is being deleted, there is no value in
-+
+   updating the current record from the query result. Instead, a new event handler
-+
+   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
-+
+   an OnDeleteReturning event handler is provided then it is called with the IResults returned
-+
+   by the query. The event handler can then interrogate the query results and
-+
+   perform whatever action is necessary. For example to confirm, to the user,
-+
+   the deletion of a row with the returned values.
-+
-+
+. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
-+
+   any Computed By or Identity Columns. The IBTables example has been updated to
-+
+   illustrate the computation of the employee Full Name on update.
-+
-+
+. TIBTable: The GeneratorField property is now published.
-+
-+
+. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
-+
+   When InsertSQL is generated, the Identity columns are not included in the list of values to
-+
+   be inserted. A RETURNING clause is added to the insert statement to return the value of
-+
+   each Identity column after the insert is executed.
-+
-+
+. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
-+
+   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
-+
+   Insert..Returning clause.
-+
-+
+. TIBGenerator: small performance improvement by not preparing query each time
-+
+   a new value is generated.
-+
-+
+. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
-+
-+
+. Property editors will now sync table name to a System Table when "Include System
-+
+    Tables" is selected and the query is for a System Table.
-+
-+
+. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
-+
+    values are no longer converted to milliseconds from TDateTime and then back again
-+
+    to TDateTime (the conversion to milliseconds is the default TDataset approach).
-+
-+
+. Property Editors handling of Stored Procedures.
-+
+    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
-+
+      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
-+
+      query).
-+
+    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
-+
-+
+. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
-+
+    can be used to select a package. If non-empty, the stored procedure name is
-+
+    expected to be a stored procedure defined in the specified package and the
-+
+    generated SQL will be as required for a stored procedure located in a package.
-+
-+
+. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
-+
+    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
-+
+    which a stored procedure can be selected. With no package name selected, non-package
-+
+    stored procedures are listed.
-+
-+
+. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
-+
+    for password on reconnect.
-+
-+
+. TIBDatabase: use IAttachment for connection default character set id, code page
-+
+    and character set name.
-+
-+
+. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
-+
+    DB info lookups"
-+
-+
+. IBExtract: now supports DDL Triggers and Grants to DDL objects.
-+
-+
+. Add a property Editor for TIBUpdate.RefreshSQL.
-+
-+
+. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
-+
+    parameters. This stops an exception being raised when the field cannot be
-+
+    located in the record buffer.
-+
-+
+. Property Editors now automatically include System Tables when opened and when the query table
-+
+    is a System Table.
-+
-+
+. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
-+
+    This avoids errors due to a stale SQRB or SRB being used for the next query.
-+
-+
+. IBServices: Service attach parameters now include "expected_db". This is used to
-+
+    add the SPB item isc_spb_expected_db. This names a database using
-+
+    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
-+
+    database. examples/services re-written to illustrate use of "expected_db".
-+
-+
+. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
-+
+    This avoids truncated backups when the server returns a timeout (busy) response.
-+
-+
+. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
-+
-+
+. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
-+
+    databasenames. These are respectively expanded to the local system's temp directory
-+
+    (including trailing delimiter) or to a prescribed data directory (including
-+
+    trailing delimiter). Under Unix systems the data directory is a hidden directory
-+
+    in the user's home directory. The hidden directory name is either the string returned
-+
+    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
-+
+    Under Windows, the directory is the same as the Data Directory as decribed
-+
+    above but instead prefixed by the User's application data path. These may be
-+
+    used to improve application portability for Personal Databases.
-+
-+
+. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
-+
+    this has not worked for a long time and is not useful either. FieldDefs should be
-+
+    managed using the Fields Editor as with any other dataset. To access the fields
-+
+    editor for a TIBTable component, double click on the component. The fields editor
-+
+    is then displayed.
-+
-+
+. TIBDatabaseInfo: new properties/function
-+
+     * DateDBCreated (returns date/time database created)
-+
+     * TransactionCount (returns no. of active transactions)
-+
+     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
-+
+     * PagesFree (Firebird 3 or later)
-+
+     * PagesUsed (Firebird 3 or later)
-+
+     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
-+
+     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
-+
-+
+. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
-+
-+
+. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
-+
-+
+. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
-+
+    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
-+
-+
+. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
-+
+    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
-+
+    firing during backup and restore.
-+
-+
+. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
-+
+    for verbose output using the new property "StatisticsRequested".
-+
+    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
-+
-+
+. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
-+
-+
+. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
-+
+    palette. This uses the online validation feature added in Firebird 2.5. The
-+
+    services's properties enable inclusion/exclusion of tables and indexes using
-+
+    regular expressions. See.
-+
+    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
-+
-+
+. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
-+
+    option on a database.
-+
-+
+. TIBCustomService: Assign method implemented to allow copying of service login
-+
+    context between service API components. "Detach" method now only detaches
-+
+    service when last reference to the service interface detaches. Tidy up of
-+
+    code for SetActive and Attach methods including password hiding.
-+
-+
+. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
-+
+    and used to determine the auth method and protocol used for the connection.
-+
-+
+. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
-+
+    a Create Database Statement generated by IBX.
-+
-+
+. All IBServices now have an additional published property "PortNo". This may
-+
+    be set to a non-standard port number when necessary. If zero then the default
-+
+    port number is used.
-+
-+
+: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
-+
+    and not just the mouse.
-+
-+
+. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
-+
-+
+. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
-+
+    image index and selected image index for each node to be set from a database field.
-+
-+
+. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
-+
+    then database schema includes grants to all users. If not present then the
-+
+    only user grants included are those to User PUBLIC.
-+
-+
+. TIBTreeView: performance improvement. When expanding include both expanded node
-+
+    and child nodes in dataset.
-+
-+
-+
+IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
-+
-+
+. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
-+
+   changes.
-+
-+
+. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
-+
+   Bug could result in truncated multi-byte character set values.
-+
-+
+. Changes consequential on moving fbintf character set utility functions from
-+
+   IFirebirdAPI to IAttachment.
-+
-+
+. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
-+
-+
+. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
-+
+   results in autocomplete ignoring prefix text.
-+
-+
+. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
-+
+   entering a new name into the text box.
-+
-+
+. IBCustomDataset: ensure that TIBStringField uses the field size reported by
-+
+   Firebird rather than recomputing it.
-+
-+
+. Property Editor positioning tidy up: All IBX Property editors should now be
-+
+   screen centre. Previously some were "poDesigned" which may be inappropriate
-+
+   for multi monitor desktops.
-+
-+
+. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
-+
-+
+. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
-+
+    a transaction and always reset the object.
-+
-+
+. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
-+
-+
+. TIBXScript: Allow for override of database filename in Create Database statements.
-+
-+
+. IBLocaldb: Support initialisation of the database from an SQL script in addition
-+
+    to a gbak format archive.
-+
-+
+. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
-+
-+
+. IBLocaldb: Drop database if error creating an empty database.
-+
-+
+. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
-+
+    unless selected node not in current dataset.
-+
-+
+. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
-+
+    to TIBCustomService, and IBlocalDB code tidy up.
-+
-+
+. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
-+
+    behaviour due to uninitialised variable.
-+
-+
+. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
-+
+    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
-+
-+
+. IBSQL: When Database changed ensure that all resources are freed.
-+
-+
+. IBCustomDataset: When database changed ensure that queries an unprepared.
-+
-+
+. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
-+
+    * Line Wrap on SQL Token boundaries (on user command)
-+
+    * auto-complete table names in drop down list of table names
-+
+    * Double click on tablename or field name adds to SQL text
-+
-+
+. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
-+
-+
+. IBTreeView: Call to FindNode: param type change from "array of Variant" to
-+
+    TVariantArray. Seems to avoid memory corruption in Windows (probably a
-+
+    workaround for a problem in fpc 3.0.4 win64).
-+
-+
+. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
-+
-+
+. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
-+
+IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
+. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
+   that BindFields is called when the query is next activated. Avoids FieldName
+   not found error.
-+
+. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
-+
+   purpose and allows the programmer to define any action they want for Update, Insert
-+
+   or Delete. This may be complex SQL (similar to a Trigger), application specific
-+
+   filtering of updates, or use of statements such as Grant or Revoke instead of
-+
+   normal DML. See User Manual for more information.
-+
+IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
+. TIBEvents: Fix uninitialised variable that could result in lost events.
