+IBX Change Log  version (2.6-4 Build 14094) Sat, 21 Oct 2023 15:03:30 +0100
-+
-+
+. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
-+
+   if ApplyUpdates called before a cursor exists.
-+
-+
+. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
-+
+   creating the blob.
-+
-+
+IBX Change Log  version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
-+
-+
+. Update to calls to EInterbaseError to add default code page. Consequential
-+
+   on change to fbintf.
-+
-+
+. Update some examples to replace test for null date with the NullDate constant
-+
+   instead of zero. This is because Laz 3.0 changes the value of NullDate.
-+
-+
+IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
-+
-+
+. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
-+
+   with later versions of fpc - later than 3.2.2.
-+
-+
+. IBUpdateSQL. update internal queries if parent dataset database changed.
-+
-+
+. IBUpdateSQL: Do not prepare an empty internal query.
-+
-+
+. IBBufferedCursors: avoid range error when max field no. is > fields.count
-+
-+
+. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
-+
-+
+IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
-+
-+
+. Maintenance update of 2.6.0. This version is still at beta.
-+
-+
+. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
-+
+   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
-+
-+
+. ibxscript: When parsing a store procedure or function with a variable name
-+
+   enclosed in doublequotes, the double quotes are no longer removed.
-+
-+
+IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
-+
-+
+NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
-+
+      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
-+
+      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
-+
+      ISSUES TO support@mwasoftware.co.uk
-+
-+
+. Complete rewrite of internal buffer management in order to improve performance
-+
+   and maintainability. Highlights:
-+
-+
+   * Extending the size of the buffer pool no longer has to copy the entire record
-+
+     cache. Instead, a new extent is simply added to the buffer pool.
-+
+   * A memory to memory copy of each display buffer now is avoided when scolling the
-+
+     dataset.
-+
+   * A separate set of buffers is now used for calculated fields. This avoids
-+
+     having to keep copies of calculated field values in the buffer cache.
-+
+   * Compact bitmaps are used to record null status and need to refresh in each
-+
+     buffer.
-+
+   * Display buffer type changed from PChar to TRecordBuffer in line with change of
-+
+     buffer type in FCL-DB.
-+
-+
+. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
-+
+   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
-+
-+
+. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
-+
+   If either or both of these flags are set at design time (using the fields editor)
-+
+   then this forces a row refresh on respectively insert or update, or both, when the
-+
+   corresponding field is not present in an SQL RETURNING clause.
-+
-+
+. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
-+
+   maintainability and readability and to add identification of primary key fields.
-+
-+
+. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
-+
+   as a refresh of the current row. However, this is different behaviour to that described
-+
+   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
-+
+   the dataset from the underlying database, and attempts to reposition the cursor on
-+
+   the same record as it was". IBX now complies with the FPC definition of Refresh.
-+
-+
+. A progammatic Row Refresh should no longer be required.
-+
+   Use Insert/Update... returning to refresh any fields that may change following an
-+
+   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
-+
+   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
-+
+   for the field at Design Time to force a row refresh if not in the returning clause.
-+
-+
+. It should now be possible to insert a row into an empty unidirectional dataset.
-+
-+
+. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
-+
+   This gives the number of buffers in the initial block for the buffer pool in
-+
+   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
-+
+   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
-+
+   for small datasets.
-+
-+
+IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
-+
-+
+. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
-+
-+
+. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
-+
-+
+. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
-+
-+
+IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
-+
-+
+. TIBTransaction: new properties
-+
+    property TransactionID: integer read GetTransactionID;
-+
+    property IsReadOnly: boolean read GetIsReadOnly;
-+
+    {published}
-+
+    property TransactionName: string read FTransactionName write SetTransactionName;
-+
-+
+. IBCustomDataset: per row blob and array buffer cached clear before processing
-+
+   Insert or Update...Returning. This allows blobs and arrays to be returned
-+
+   by the statement.
-+
-+
+. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
-+
-+
+. TransactionName initialised to a newly generated GUID if empty.
-+
-+
+. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
-+
+   for the fbintf package's journaling capability. TIBJournal is used to set the
-+
+   file path and filename for the journal file and to Enabled (start journaling) and
-+
+   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
-+
+   more information, and comments in IBJournal.pas.
-+
-+
+. TIBDatabase.InternalTransaction is now a read only transaction.
-+
-+
+. Bug fix: blob id no longer set to null on update when blob has not been
-+
+   retrieved.
-+
-+
+. Row auto refreshed on update/insert if blob or array field updated and field
-+
+   not in a returning clause.
-+
-+
+. ColumnCount moved from record buffer header to a single per dataset count. Reduces
-+
+   buffer overhead and avoids problem when refresh query has a different column
-+
+   count to select query i.e. incorrectly changing number of columns.
-+
-+
+. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
-+
-+
+. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
-+
+    string. Note that the Version property returns an InterBase compatible version string.
-+
-+
+. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
-+
-+
+IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
-+
-+
+. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
-+
+   This is for compatibility with Firebird 5 where Update...Returning can return
-+
+   a cursor.
-+
-+
+IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
-+
-+
+. Add try-..except check when initially loading library in IDE. This should
-+
+ensure that IDE continues to load even when a failure occurs in IBX load
-+
+library.
-+
-+
+. IBXScript: now recognises a CASE...END block within a stored procedure and
-+
+   hence will correctly detect end of the outer containing block when the block
-+
+   contains a SELECT ... CASE ... END construct.
-+
-+
+. IBExtract: some further tidying up to remove extraneous white space.
-+
-+
+. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
-+
+   errors when extra elements are added to DB.TFieldType.
-+
-+
+. IBUpdate: updated to reflect changes to ISQLParam.
-+
-+
+. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
-+
-+
+. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
-+
-+
+. IBSQL: Support for scrollable cursors added (note: local databases only)
-+
-+
+IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
-+
-+
+. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
-+
+   exception of those defined to be one byte wide e.g. DBImplementationNo.
-+
-+
+. TIBSQL: Batch Update/Insert support added.
-+
-+
+. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
-+
+   is no longer automatically converted to upper case when it is syntactically a
-+
+   SQL Identifier. This is to support the use of stored procedures defined e.g.
-+
+   as CREATE PROCEDURE "iCASE".
-+
-+
+   There could be a backwards compatibility issue when the StoredProcName was entered
-+
+   manually at design time. That is not selected from the drop down list. If the
-+
+   StoredProcName is entered in mixed case and the procedure was declared e.g. as
-+
+   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
-+
+   ensure that the value of the StoredProcName is all upper case, unless it was
-+
+   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
-+
+   quotes).
-+
-+
+   Note that when a stored procedure name was declared delimited in double quotes,
-+
+   as in the first example above, the value of the StoredProcName property must not
-+
+   include the delimiters (double quotes).
-+
-+
+. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
-+
+   upgrade.conf was not found. This replaces silently ignoring the problem.
-+
-+
+. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
-+
+   'Version.%.3d' and is used to generate the section header names (for a given
-+
+   version no.) in the upgrade.conf file.
-+
-+
+IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
-+
-+
+. -c command line option added to fbsql example program. Used to set connection
-+
+   character set.
-+
-+
+IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
-+
-+
+. Firebird 4 support added.
-+
-+
+. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
-+
+   extended precision NUMERIC fields are supported.
-+
-+
+. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
-+
-+
+. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
-+
+   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
-+
-+
+. IBExtract now supports FB4 enhancements:
-+
+   - new data types as above
-+
+   - Identity column extensions
-+
+   - Default user role
-+
+   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
-+
+   - Internal Functions
-+
-+
+. IBExtract: new event: OnExtractLines.
-+
-+
+. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
-+
-+
+. IBXServices: Server version no. parsing now allows any letter before major version number
-+
+   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
-+
-+
+. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
-+
+   format for rendering a time zone.
-+
-+
+. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
-+
+     to convert TIME WITH TIME ZONE data type values to and from GMT.
-+
-+
+. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
-+
+    IIBGUIInterface and IIBTimerInf respectively.
-+
-+
+. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
-+
+    now accessible as properties of TIBDatabase and TIBTransaction respectively.
-+
-+
+. String Fields: when a fixed character with (CHAR) field is returned, it is now
-+
+    truncated to its fixed character width rather than being right padded with
-+
+    white space to the maximum data size.
-+
-+
+. TIBTable.Empty table. In additional to deleting all records in the underlying
-+
+    table, the internal buffers are now also flushed ensuring that the TIBTable is
-+
+    also empty.
-+
-+
+. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
-+
-+
+. TIBXControlService descendents: DatabaseName may now be set using a database
-+
+    connect string. The database name is extracted from the connect string.
-+
-+
+. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
-+
-+
+. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
-+
-+
+. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
-+
+    not being present as required.
-+
-+
+. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
-+
+    version that can be customised to work with other database drivers.
-+
-+
+. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
-+
+    unnecessary CR at end of line on Unix platforms.
-+
-+
+. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
-+
+    seconds in order to reduce risk of message loss.
-+
-+
+. ISQLMonitor: read and write count statistics now available via:
-+
+      property TIBSQLMonitor.ReadCount;
-+
+      IIBSQLMonitorHook.GetWriteCount: integer;
-+
-+
+. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
-+
-+
+IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
-+
-+
+.  TIBStringField: when a string value is read from a dataset buffer, if the
-+
+    number of UTF8 characters exceeds the string size then string is truncated
-+
+    to the maximum string size. This is  usually a problem with fixed width columns
-+
+    right padded with white space.
-+
-+
+.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
-+
+    If SQLFiltered is set then when a dataset is opened, each line in the
-+
+    SQLFilterParams property is assumed to be a SQL condition clause and
-+
+    ANDed into the Where clause of the SQL Select statement provided as a
-+
+    dataset property. Each such SQL condition thus acts as an additional filter
-+
+    on the dataset.
-+
-+
+.  The Filtered property inherited from TDataset is no longer used for SQL (server
-+
+    side filters).
-+
-+
+. IBLookupComboEditBox: Selection should no longer reset to start of text when
-+
+   text matches complete entry.
-+
-+
+. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
-+
+   dataset are active (avoids risk of access violation if master is inactive)
-+
-+
+. TIBEvents: Registered property can now be set at design time even if database not open
-+
-+
+. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
-+
+   This should prevent "spillover" of events between sessions.
-+
-+
+. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
-+
+   This should ensure that the internal buffer is set up correctly and avoids
-+
+   a duplicate initial row.
-+
-+
+. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
-+
+   That is, the DataSize should be the field size * character set width. The
-+
+   value returned by DataSize is now the same as the Dataset buffer size reserved
-+
+   for the field.
-+
-+
+. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
-+
-+
+. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
-+
+    and vice-versa. This may result in an exception being raised (correctly) for
-+
+    older programs when using dataset fields added to a form and the database has been
-+
+    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
-+
+    In such cases, the field needs to be deleted in the IDE fields editor and then
-+
+    added back in.
-+
-+
+. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
-+
+    false if query contains only white space and not just empty.
-+
-+
+. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
-+
+    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
-+
+    is cancelled.
-+
-+
+. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
-+
+    called on a null field.
-+
-+
+. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
-+
+    results in an empty dataTC86                Client side Filtered Dataset    1       X
-+
+set.
-+
-+
+. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
-+
+    a cached update is applied and an exception is raised.
-+
-+
+. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
-+
-+
+. Console Mode Local Database support: backup/restore should now work correctly.
-+
-+
+. Local Database Support: if an upgrade fails, a downgrade is now performed if
-+
+    possible and an exception raised.
-+
-+
+. MinimumVersionNo added to Local Database Support. Database will not open if
-+
+    below this version no. and upgrade not possible.
