+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.
-+
-+
+IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
-+
-+
+.  TIBXDataSet and Generators: Generator Names that are not all upper case or
-+
+    not SQL Identifiers are now supported.
-+
-+
+.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
-+
+    passed to the Firebird engine for execution.
-+
-+
+.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
-+
+    is made to scroll back.
-+
-+
+.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
-+
-+
+. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
-+
+   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
-+
-+
+. TIBLookupComboEditBox: when the list source opens, the ListField name is now
-+
+   validated. If no match is found in the list of field names and the database has
-+
+   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
-+
+   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
-+
-+
+. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
-+
+   with fpc 3.2.
-+
-+
+IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
-+
-+
-+
+. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
-+
+   and is used to override the default settings in the client side "firebird.conf" This
-+
+   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
-+
+   Each line of the string list should be a setting in the same format as "firebird.conf".
-+
+   For example "WireCompression = true" in order to request wire compression on the client side.
-+
-+
+   Note: explicit settings in the client side "firebird.conf" appear to take precedence
-+
+   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
-+
+   also require a compatible setting in the server side "firebird.conf". For example
-+
+   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
-+
+   compression to be used.
-+
-+
+   Whether or not WireCompression or WireCrypt are in use can be checked using the information
-+
+   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
-+
+   ibx/examples/dbinfo for examples of how to display this information.
-+
-+
+. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
-+
+   is a "convenience" property. If set the "WireCompression=true" is added to the
-+
+   ConfigOverrides. If unchecked then this setting is removed.
-+
-+
+. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
-+
+   not "INT64".
-+
-+
+. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
-+
+   These are:
-+
+    property TimestampFormat: string;
-+
+    property DateFormat: string;
-+
+    property TimeFormat: string;
-+
-+
+   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
-+
+   DATETIME and TIME. The format strings use the standard FPC date/time format
-+
+   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
-+
-+
+   If any of the above properties are set to an empty string, then the locale default
-+
+   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
-+
+   locale default is extended by appending '.zzz' to include milliseconds.
-+
-+
+   TIBCSVDataOut by default sets these properties to the empty string, while the other
-+
+   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
-+
-+
+. New published property for TIBCSVDataOut:
-+
+     property QuoteStrings: boolean (default true)
-+
-+
+   If false then strings are unquoted, otherwise, the QuoteChar property value is
-+
+   used to delimit each and every string in the output.
-+
-+
+. New published properties for TIBCSVDataOut:
-+
+    property FieldSeparator: string;
-+
+    property HeaderSeparator: string;
-+
-+
+   Respectively, these provide the separator character(s) used to separate fields
-+
+   in data and header rows. Both default to ','.
-+
-+
+. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
-+
+    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
-+
+    property OnFormatTextString;
-+
-+
+   This event handler can be used to process text strings before they are included
-+
+   in the output e.g. to replace unprintable characters with alternative strings.
-+
+   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
-+
-+
+. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
-+
+   Uses "FindParam" if in order to find out if a parameter with a given name exists
-+
+   and without raising and exception if it does not.
-+
-+
+. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
-+
+   consistency with SQL queries.
-+
-+
+. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
-+
+    When true, SQL statement parameter names are parsed case sensitive. Note for
-+
+    TIBDataSet only applies to Select query.
-+
-+
+. IBEvents: removing a TIBEvent component from a form should no longer result in
-+
+    an IDE exception.
-+
-+
+. LocalDBSupport: initial database creation should now work correctly
-+
+    when the schema source is an sql file.
-+
-+
+. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
-+
+    when defined, this handler will be called by the internal TIBXScript during
-+
+    initial database creation when the schema source is an sql file and may be used
-+
+    to provide a visual indication of progress in console mode.
-+
-+
+. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
-+
+    to true while a new local database is being created and its schema populated.
-+
+    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
-+
+    when the database is disconnected/connected during the create DB procedure.
-+
-+
+. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
-+
+    are now always ignored and replaced by the user name and password provided as
-+
+    the login parameters for the TIBDatabase referenced from the TIBXScript. The
-+
+    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
-+
+    completely ignored if this property is true.
-+
-+
+. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
-+
+    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
-+
+    ImageIndex and SelectImageIndex values on AddNode.
-+
-+
+. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
-+
+    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
-+
+    the same database connection.
-+
-+
+. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
-+
+    if provided, this should be an conditional SQL expression suitable for
-+
+    including in an SQL Select statement "where" clause. If non-empty and the
-+
+    "Filtered" property is true then the SQL expression provided as the value of
-+
+    the "Filter" property is "ANDed" with any existing condition statement
-+
+    in the SQL statement's "Where" clause.
-+
-+
+    If the "Filter" property is set at run time, the "Filtered" property is true
-+
+    and the dataset is already open, then the dataset is closed and re-opened automatically.
-+
-+
+    The "Filter" condition may include IBX style parameters. In which case, their
-+
+    value must be set by the dataset's "OnBeforeOpen" event handler.
-+
-+
+    This is a public property for TIBDataSet and TIBQuery query and intended for
-+
+    use at run time.
-+
-+
+    Note: The property is a published property of TIBTable. The TIBTable functionality
-+
+    is unaffected by this change.

+IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
-+
-+
+. Remove need to check for IsMultiThread by providing access to GUI timers via
-+
+   IBGUIInterface. Note: master/detail delay timer does not apply to console
-+
+   mode apps.
-+
-+
+. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
-+
+   statement. This avoids problems if "Execute Block" is used as the Query.
-+
-+
+. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
-+
+   internal SQL tokeniser routines.
-+
-+
+. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
-+
+   as a select statement, with or without CTEs.
-+
-+
+. IBSQLParser: parser now recognises the "ROWS" clause.
-+
-+
+. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
-+
+   internal SQL tokeniser routines.
-+
-+
+.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
-+
+    being raised for valid set statements processed by a data formatter.
-+
-+
+. New published property for TIBDatabase and TIBXServicesConnection. This is
-+
+   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
-+
+   the path of the Firebird Library used by the database/services connection.
-+
-+
+. New read only public property for TIBDatabase and TIBXServicesConnection. This
-+
+   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
-+
+   services connection.
-+
-+
+.SQL Property editors now quote parameter names if "Quote identifier" is selected
-+
+   or param name is not a valid SQL identifier.
-+
-+
+. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
-+
+    view of whether the text box should be editable when no DataSource is specified.
-+
+    TIBLookupComboEditBox has been updated to workaround this problem. As long as
-+
+    ReadOnly is false, the text box is editable when no DataSource is specified.
-+
-+
+. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
-+
+    the FBLIB environment variable. If you do not want to permit this then you
-+
+    must modify the Register procedure in the design/IBDBReg.pas unit to remove
-+
+    this setting.

-+
+   Utf8EscapeControlChars

-+
+IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +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.
-+
-+
+. TIBXScript: If an exception occurs during the processing of a statement, the
-+
+    statement separate character is now reset to the default (';').
-+
-+
+. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
-+
-+
+. TIBXScript: Transaction is no longer automatically reactivated immediately processing
-+
+    a commit or reconnect statement and instead activated only when next SQL statement
-+
+    is executed.
-+
-+
+. TIBSQL.HasField should no longer generate and exception when the field does not exist.
-+
-+
+. TIBXScript: case insensitive regex now used when matching statements instead of
-+
+    converting statement to upper case.
-+
-+
+. TIBExtract: metadata comments now supported. New published property
-+
+    IncludeMetaDataComments (default true). If true then metadata comments included
-+
+    in extracted DDL. New Extract Object member eoComments. This may be used with
-+
+    ExtractObject method to list all metadata comments.
-+
-+
+. TIBExtract: ListObjectNames method added.
-+
-+
+. Updated Database component editor to support additional connection string
-+
+    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.
