+IBX Change Log  version                                   (2.1-1) Fri, 12 Jan 2018 10:13:29 +0000
-+
-+
+. IBExtract: Identity columns - add addition 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). Values returned as a result of executing an Insert or Update statement
-+
+   replace existing values in the current row for each corresponding column.
-+
-+
+. 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.
-+
-+
+. TIBGenerator: small performance improvement by not preparing query each time
-+
+   a new number is generated.
-+
-+
+. TIBSQL: Free resources when transaction changed.
-+
-+
+. Property editor will now sync table name to a System Table when "Include System
-+
+   Tables" is selected and the query is for a System Table.
-+
-+
+. 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.
-+
-+
+. 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
-+
+   the TDateTime (the TDataset approach).
-+
-+
+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
-+
+   include remote system name.
-+
-+
+. TIBExtract: No longer include comment header and COMMIT statement for empty
-+
+   tables when data included in output.
-+
-+
+. Profiling: IBSQL now has conditional compilation flags to enable query performance
-+
+   and timing information to be written to stdout. This may be used to locate
-+
+   performance bottlenecks.
-+
-+
+. SQLParser: only call "OnChanging" event handler when value is different.
-+
-+
+. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
-+
-+
+. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
-+
+   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.
-+
-+
+. TIBExtract: Added support for FB3 "USAGE" privilege.
-+
-+
+. TIBExtract: data formatted as Charset set "octets" is now output using
-+
+   hexadecimal notation.
-+
-+
+. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
-+
+   using a simple XML format.
-+
-+
+. TIBExtract: extract of individual Triggers and Stored Procedures can now include
-+
+   grants to these objects.
-+
-+
+. TIBExtract: Stored Procedures and Views output in dependency order to avoid
-+
+   dependency problems restoring complex databases.
-+
-+
+. TIBXScript: This component has been restructured to allow for the processing of
-+
+   embedded XML in INSERT statements and to support interactive sources in addition
-+
+   to non-interactive data sources such as files.
-+
-+
+. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
-+
-+
+. TIBXScript: ISQL compatiable Set statements are now supported:
-+
+   SET SQL DIALECT
-+
+   SET TERM
-+
+   SET AUTODDL
-+
+   SET BAIL
-+
+   SET ECHO
-+
+   SET COUNT
-+
+   SET STATS
-+
+   SET NAMES <character set>
-+
-+
+. IBVersion unit added to hold current IBX Version Number information.
-+
-+
+. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
-+
+    and domain definitions.
-+
-+
+. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
-+
+    fully supported.
-+
-+
+. TIBExtract: when a database dump includes data, the generator values are now also set.
-+
-+
+: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
-+
-+
+IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
-+
-+
+See also doc/IBX4LazarusGuide.pdf for important information on
-+
+upgrading to IBX2.
-+
-+
+. Size property of TIBStringField is now the width in characters of the field
-+
+   and not the byte length. This applies only to multi-byte character sets such
-+
+   as UTF8. The original approach aligned with TStringField. However, the TStringField
-+
+   code is not recognised as a bug and hence this change to align the behaviour.
-+
+   The TStringField change is expected in fpc 3.2.0.
-+
-+
+. A new property AutoFieldSize: boolean has been added to TIBStringField. When
-+
+   true (default) then Size property value saved in the lfm is ignored. Size is
-+
+   always set from the dynamic information read from the database. It is unclear
-+
+   why anyone would want to override this and set Size to false.
-+
-+
+. ibxscript: should now handle correctly a Case..End statement within a procedure
-+
+   block.
-+
-+
+. IBDatabase: new property - CreateIfNotExists. If true and database does not
-+
+   exist when an attempt is made to connect to it (run time only) then an attempt
-+
+   is made to create the database.
-+
-+
+. IBDatabase: new event - OnCreateDatabase. This event is called after a database
-+
+   has been successfully created as a result of a call to CreateDatabase or when
-+
+   creating a database after it was found not to exist.
-+
-+
+.  DBControlGrid: a race condition could result in the wrong row image being
-+
+    written to the cache. This has been avoided by a trip round the message
-+
+    loop before rendering the row image.
-+
-+
+.  DBControlGrid: It is strongly recommended not to open the source DataSet for
-+
+    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
-+
+    known to risk corrupt rendering of row images when the control is first
-+
+    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
-+
+    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
-+
-+
+.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
-+
+    a TDateEdit control located on an editor panel.
-+
-+
+.  TIBExtract: brought up-to-date plus many bug fixes.
-+
-+
+. DBControlGrid: Removed memory leak when updating rows.
-+
-+
+. TIBCMLocalDBSupport: fixed invalid free on upgrade.
-+
-+
+IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
-+
-+
+. IBCustomDataset: When calling SetCodePage, no longer request transliteration
-+
+   when target codepage is CP_NONE. This is a workaround for
-+
+   http://bugs.freepascal.org/view.php?id=30622.
-+
-+
+. DBLog option removed from TIBStatisticalService - not supported by server
-+
+   since Firebird 1.5.
-+
-+
+. ibxscript: An error is no longer generated for "on commit preserve rows" or
-+
+   similar.
-+
-+
+. IBCodePage: updated mapping between codepages and character id.
-+
-+
+. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
-+
+   Firebird. Character sets with a char width of two are not UTF16.
-+
-+
+. Strings received from the database are now always transliterated into UTF8
-+
+   regardless of the database character set or connection character set. This
-+
+   is for compatibility with the LCL.
-+
-+
+IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
-+
-+
+. IBBlob: Defer reading of blob until read method called. This avoids having to
-+
+   read in an entire blob just to get the size of the blob. General performance
-+
+   improvement when opening datasets containing blobs.
-+
-+
+. Clearing a  Blob now sets the corresponding field's modified flag.
-+
-+
+. IBLookupCombo: When not performing auto-complete, original query sort order
-+
+   is now used.
-+
-+
+. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
-+
+   determined.
-+
-+
+. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
-+
-+
+. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
-+
+   lazarus 1.6.0
-+
-+
+. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
-+
+   compilation error.
-+
-+
+IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
-+
-+
+. No character set specified for connection: when a text blob is retrieved, the
-+
+  character set is determined by looking up the native character set using then
-+
+  Firebird API. Otherwise a text mode blob is assumed to have the same character
-+
+  set as the connection.
-+
-+
+. TIBGUIInterface: this is an internal interface. Minor type changes to allow
-+
+   for Login Dialog returing a change to the database path.
-+
-+
+. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
-+
+   to be changed from that given in the TIBDatabase/TIBServer component and for the
-+
+   entered value to be saved on a project specific basis (design time only).
-+
-+
+. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
-+
+   column fieldname. If they are the same then it is acts as a look up for the KeyValue
-+
+   Otherwise, it sets the column text to the selected ListField Value.
-+
-+
+. IBDynamicGrid: Only visible columns are now taken into account When recalculating
-+
+   column width.
-+
-+
+. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
-+
+   and a case insensitive search is requested.
-+
-+
+. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
-+
+   or column ListSource.
-+
-+
+. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
-+
+   unprepare) when closing and the text has not changed.
-+
-+
+. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
-+
+   Less likely to cause a cursor re-use error on Windows.
-+
-+
+.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
-+
+   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
-+
-+
+. TIBTreeView: Guard against nil destination on record changed
-+
-+
+. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
-+
+    string type with the code page set to reflect the returned field encoding after
-+
+    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
-+
+    earlier versions.
-+
-+
+. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
-+
+    will now result in transliteration to the code page specified for the Firebird driver
-+
+    if the assigned string has a different code page. FPC 3.0.0 onwards only.
-+
-+
+. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
-+
+    is ignored and the lc_ctype value, when the database is opened, is set to align with
-+
+    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
-+
+    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
-+
+.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
-+
+    the GETACP is used to determine the Windows code page.
-+
-+
+. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
-+
+    name used as the lc_ctype when the database was opened. Only valid while the
-+
+    Database is connected.
-+
-+
+. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
-+
+    id that corresponds to the DefaultCharSetName.
-+
-+
+IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
-+
-+
+. Unix: If Firebird Embedded Server shared object is loaded and a local database
-+
+   path is given and database attach fails due to access permission issues on the
-+
+   temp directory or security database, then the attach is retried with "localhost:"
-+
+   prefixing the databasename. This should avoid problems when the database has to
-+
+   be accessed by a local (e.g. classic) server and libfbembed is used.
-+
-+
+. Windows: revised search order for Firebird DLL:
-+
+     i.   The Firebird Embedded Server in the application Directory.
-+
+     ii.  If the FIREBIRD environment variable is set then the directory this
-+
+          points to is searched for the FB Client DLL and then then underlying
-+
+          "bin" directory.
-+
+     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
-+
+          is used to locate the Firebird installation directory and the underlying
-+
+          "bin" directory is searched for the FB Client DLL.
-+
+     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
-+
+          are searched for the FB Client DLL.
-+
+     v.   The PATH Environment variable is used to search for the FB Client DLL.
-+
+     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
-+
-+
+. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
-+
+   See doc/readme.scriptengine and example applications.
-+
-+
+. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
-+
+   simplify the use of the embedded firebird server on both Linux and Windows platforms.
-+
+   See dpc/readme.localdatabase and example applications.
-+
-+
+. IBDynamicGrid: Reordering on column header click should now also work for
-+
+   dynamic columns.
-+
-+
+. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
-+
+   between incrementing/decrementing the lock count and signalling the event.
-+
-+
+IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
-+
-+
+.3.2 was never formally released and only made available as beta copies.
-+
-+
+. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
-+
-+
+. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
-+
-+
+. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
-+
-+
+. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
-+
+   i.e. when it is a calculated field
-+
-+
+. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
-+
+   This problem was due to a race condition between recalculating row heights and
-+
+   determining which row was selected by the mouse click. The row height calculation
-+
+   is now deferred by an extra trip round the message loop allowing the row to
-+
+   be always calculated on the current grid layout rather than risking it being
-+
+   calculated on the grid layout after the expanded row has been shrunk.
-+
-+
+. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
-+
+   Windows.
-+
-+
+. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
-+
+   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
-+
+   to be determined at runtime. See doc/readme.charactersets.html.
-+
-+
+. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
-+
+   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
-+
-+
+. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
-+
+   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
-+
+, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
-+
-+
+   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
-+
+   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
-+
+   implies no truncation.
-+
-+
+. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
-+
-+
+. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
-+
+   (avoids "Not in Edit Mode" error).
-+
-+
+. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
-+
-+
+. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
-+
+    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
-+
-+
+. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
-+
-+
+. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
-+
-+
+. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
-+
-+
+. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
-+
+IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
