25	>
26	>	NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
27	>	AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
28	>	BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
29	>	ISSUES TO support@mwasoftware.co.uk
30	>
31	>	1. Complete rewrite of internal buffer management in order to improve performance
32	>	and maintainability. Highlights:
33	>
34	>	* Extending the size of the buffer pool no longer has to copy the entire record
35	>	cache. Instead, a new extent is simply added to the buffer pool.
36	>	* A memory to memory copy of each display buffer now is avoided when scolling the
37	>	dataset.
38	>	* A separate set of buffers is now used for calculated fields. This avoids
39	>	having to keep copies of calculated field values in the buffer cache.
40	>	* Compact bitmaps are used to record null status and need to refresh in each
41	>	buffer.
42	>	* Display buffer type changed from PChar to TRecordBuffer in line with change of
43	>	buffer type in FCL-DB.
44	>
45	>	2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
46	>	to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
47	>
48	>	3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
49	>	If either or both of these flags are set at design time (using the fields editor)
50	>	then this forces a row refresh on respectively insert or update, or both, when the
51	>	corresponding field is not present in an SQL RETURNING clause.
52	>
53	>	4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
54	>	maintainability and readability and to add identification of primary key fields.
55	>
56	>	5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
57	>	as a refresh of the current row. However, this is different behaviour to that described
58	>	in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
59	>	the dataset from the underlying database, and attempts to reposition the cursor on
60	>	the same record as it was". IBX now complies with the FPC definition of Refresh.
61	>
62	>	6. A progammatic Row Refresh should no longer be required.
63	>	Use Insert/Update... returning to refresh any fields that may change following an
64	>	insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
65	>	on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
66	>	for the field at Design Time to force a row refresh if not in the returning clause.
67	>
68	>	7. It should now be possible to insert a row into an empty unidirectional dataset.
69	>
70	>	8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
71	>	This gives the number of buffers in the initial block for the buffer pool in
72	>	bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
73	>	in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
74	>	for small datasets.
75	>
76	>	IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
77	>
78	>	1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
79	>
80	>	2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
81	>
82	>	3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
83	>
84	>	IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
85	>
86	>	1. TIBTransaction: new properties
87	>	property TransactionID: integer read GetTransactionID;
88	>	property IsReadOnly: boolean read GetIsReadOnly;
89	>	{published}
90	>	property TransactionName: string read FTransactionName write SetTransactionName;
91	>
92	>	2. IBCustomDataset: per row blob and array buffer cached clear before processing
93	>	Insert or Update...Returning. This allows blobs and arrays to be returned
94	>	by the statement.
95	>
96	>	3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
97	>
98	>	4. TransactionName initialised to a newly generated GUID if empty.
99	>
100	>	5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
101	>	for the fbintf package's journaling capability. TIBJournal is used to set the
102	>	file path and filename for the journal file and to Enabled (start journaling) and
103	>	disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
104	>	more information, and comments in IBJournal.pas.
105	>
106	>	6. TIBDatabase.InternalTransaction is now a read only transaction.
107	>
108	>	7. Bug fix: blob id no longer set to null on update when blob has not been
109	>	retrieved.
110	>
111	>	8. Row auto refreshed on update/insert if blob or array field updated and field
112	>	not in a returning clause.
113	>
114	>	9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
115	>	buffer overhead and avoids problem when refresh query has a different column
116	>	count to select query i.e. incorrectly changing number of columns.
117	>
118	>	10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
119	>
120	>	11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
121	>	string. Note that the Version property returns an InterBase compatible version string.
122	>
123	>	12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
124	>
125	>	IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
126	>
127	>	1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
128	>	This is for compatibility with Firebird 5 where Update...Returning can return
129	>	a cursor.
130	>
131	>	IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
132	>
133	>	1. Add try-..except check when initially loading library in IDE. This should
134	>	ensure that IDE continues to load even when a failure occurs in IBX load
135	>	library.
136	>
137	>	2. IBXScript: now recognises a CASE...END block within a stored procedure and
138	>	hence will correctly detect end of the outer containing block when the block
139	>	contains a SELECT ... CASE ... END construct.
140	>
141	>	3. IBExtract: some further tidying up to remove extraneous white space.
142	>
143	>	4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
144	>	errors when extra elements are added to DB.TFieldType.
145	>
146	>	5. IBUpdate: updated to reflect changes to ISQLParam.
147	>
148	>	6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
149	>
150	>	7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
151	>
152	>	8. IBSQL: Support for scrollable cursors added (note: local databases only)
153	>
154	>	IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
155	>
156	>	1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
157	>	exception of those defined to be one byte wide e.g. DBImplementationNo.
158	>
159	>	2. TIBSQL: Batch Update/Insert support added.
160	>
161	>	3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
162	>	is no longer automatically converted to upper case when it is syntactically a
163	>	SQL Identifier. This is to support the use of stored procedures defined e.g.
164	>	as CREATE PROCEDURE "iCASE".
165	>
166	>	There could be a backwards compatibility issue when the StoredProcName was entered
167	>	manually at design time. That is not selected from the drop down list. If the
168	>	StoredProcName is entered in mixed case and the procedure was declared e.g. as
169	>	CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
170	>	ensure that the value of the StoredProcName is all upper case, unless it was
171	>	declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
172	>	quotes).
173	>
174	>	Note that when a stored procedure name was declared delimited in double quotes,
175	>	as in the first example above, the value of the StoredProcName property must not
176	>	include the delimiters (double quotes).
177	>
178	>	4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
179	>	upgrade.conf was not found. This replaces silently ignoring the problem.
180	>
181	>	5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
182	>	'Version.%.3d' and is used to generate the section header names (for a given
183	>	version no.) in the upgrade.conf file.
184	>
185	>	IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
186	>
187	>	1. -c command line option added to fbsql example program. Used to set connection
188	>	character set.
189	>
190	>	IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
191	>
192	>	1. Firebird 4 support added.
193	>
194	>	2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
195	>	extended precision NUMERIC fields are supported.
196	>
197	>	3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
198	>
199	>	4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
200	>	and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
201	>
202	>	5. IBExtract now supports FB4 enhancements:
203	>	- new data types as above
204	>	- Identity column extensions
205	>	- Default user role
206	>	- SQL Security clause for Database, Tables, Procedures, Functions and Triggers
207	>	- Internal Functions
208	>
209	>	6. IBExtract: new event: OnExtractLines.
210	>
211	>	7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
212	>
213	>	8. IBXServices: Server version no. parsing now allows any letter before major version number
214	>	and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
215	>
216	>	9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
217	>	format for rendering a time zone.
218	>
219	>	10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
220	>	to convert TIME WITH TIME ZONE data type values to and from GMT.
221	>
222	>	11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
223	>	IIBGUIInterface and IIBTimerInf respectively.
224	>
225	>	12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
226	>	now accessible as properties of TIBDatabase and TIBTransaction respectively.
227	>
228	>	13. String Fields: when a fixed character with (CHAR) field is returned, it is now
229	>	truncated to its fixed character width rather than being right padded with
230	>	white space to the maximum data size.
231	>
232	>	14. TIBTable.Empty table. In additional to deleting all records in the underlying
233	>	table, the internal buffers are now also flushed ensuring that the TIBTable is
234	>	also empty.
235	>
236	>	15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
237	>
238	>	16. TIBXControlService descendents: DatabaseName may now be set using a database
239	>	connect string. The database name is extracted from the connect string.
240	>
241	>	17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
242	>
243	>	18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
244	>
245	>	19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
246	>	not being present as required.
247	>
248	>	20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
249	>	version that can be customised to work with other database drivers.
250	>
251	>	21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
252	>	unnecessary CR at end of line on Unix platforms.
253	>
254	>	22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
255	>	seconds in order to reduce risk of message loss.
256	>
257	>	23. ISQLMonitor: read and write count statistics now available via:
258	>	property TIBSQLMonitor.ReadCount;
259	>	IIBSQLMonitorHook.GetWriteCount: integer;
260	>
261	>	24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

263	>	IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
264	>
265	>	1.  TIBStringField: when a string value is read from a dataset buffer, if the
266	>	number of UTF8 characters exceeds the string size then string is truncated
267	>	to the maximum string size. This is  usually a problem with fixed width columns
268	>	right padded with white space.
269	>
270	>	2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
271	>	If SQLFiltered is set then when a dataset is opened, each line in the
272	>	SQLFilterParams property is assumed to be a SQL condition clause and
273	>	ANDed into the Where clause of the SQL Select statement provided as a
274	>	dataset property. Each such SQL condition thus acts as an additional filter
275	>	on the dataset.
276	>
277	>	3.  The Filtered property inherited from TDataset is no longer used for SQL (server
278	>	side filters).
279	>
280	>	4. IBLookupComboEditBox: Selection should no longer reset to start of text when
281	>	text matches complete entry.
282	>
283	>	5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
284	>	dataset are active (avoids risk of access violation if master is inactive)
285	>
286	>	6. TIBEvents: Registered property can now be set at design time even if database not open
287	>
288	>	7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
289	>	This should prevent "spillover" of events between sessions.
290	>
291	>	8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
292	>	This should ensure that the internal buffer is set up correctly and avoids
293	>	a duplicate initial row.
294	>
295	>	9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
296	>	That is, the DataSize should be the field size * character set width. The
297	>	value returned by DataSize is now the same as the Dataset buffer size reserved
298	>	for the field.
299	>
300	>	10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
301	>
302	>	11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
303	>	and vice-versa. This may result in an exception being raised (correctly) for
304	>	older programs when using dataset fields added to a form and the database has been
305	>	upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
306	>	In such cases, the field needs to be deleted in the IDE fields editor and then
307	>	added back in.
308	>
309	>	12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
310	>	false if query contains only white space and not just empty.
311	>
312	>	12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
313	>	should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
314	>	is cancelled.
315	>
316	>	13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
317	>	called on a null field.
318	>
319	>	14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
320	>	results in an empty dataTC86                Client side Filtered Dataset    1       X
321	>	set.
322	>
323	>	15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
324	>	a cached update is applied and an exception is raised.
325	>
326	>	16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
327	>
328	>	17. Console Mode Local Database support: backup/restore should now work correctly.
329	>
330	>	18. Local Database Support: if an upgrade fails, a downgrade is now performed if
331	>	possible and an exception raised.
332	>
333	>	19. MinimumVersionNo added to Local Database Support. Database will not open if
334	>	below this version no. and upgrade not possible.

337	>
338	>	1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
339	>	not SQL Identifiers are now supported.
340	>
341	>	2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
342	>	passed to the Firebird engine for execution.
343	>
344	>	3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
345	>	is made to scroll back.
346	>
347	>	4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
348	>
349	>	5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
350	>	only enclosed in double quotes in SQL dialect 3 and when it needs to be.
351	>
352	>	6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
353	>	validated. If no match is found in the list of field names and the database has
354	>	been opened in SQL Dialect 3, then the ListField Name is converted to upper case
355	>	if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
356	>
357	>	7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
358	>	with fpc 3.2.

362	>
363	>	1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
364	>	and is used to override the default settings in the client side "firebird.conf" This
365	>	includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
366	>	Each line of the string list should be a setting in the same format as "firebird.conf".
367	>	For example "WireCompression = true" in order to request wire compression on the client side.
368	>
369	>	Note: explicit settings in the client side "firebird.conf" appear to take precedence
370	>	over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
371	>	also require a compatible setting in the server side "firebird.conf". For example
372	>	"WireCompression = true" must also be set in the server's "firebird.conf" for wire
373	>	compression to be used.
374	>
375	>	Whether or not WireCompression or WireCrypt are in use can be checked using the information
376	>	returned with the Client/Server protocol version. See ibx/examples/dbadmin and
377	>	ibx/examples/dbinfo for examples of how to display this information.
378	>
379	>	2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
380	>	is a "convenience" property. If set the "WireCompression=true" is added to the
381	>	ConfigOverrides. If unchecked then this setting is removed.
382	>
383	>	3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
384	>	not "INT64".
385	>
386	>	4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
387	>	These are:
388	>	property TimestampFormat: string;
389	>	property DateFormat: string;
390	>	property TimeFormat: string;
391	>
392	>	Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
393	>	DATETIME and TIME. The format strings use the standard FPC date/time format
394	>	characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
395	>
396	>	If any of the above properties are set to an empty string, then the locale default
397	>	is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
398	>	locale default is extended by appending '.zzz' to include milliseconds.

413	>	Respectively, these provide the separator character(s) used to separate fields

418	>	property OnFormatTextString;
419	>
420	>	This event handler can be used to process text strings before they are included
421	>	in the output e.g. to replace unprintable characters with alternative strings.
422	>	This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
423	>
424	>	8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
425	>	Uses "FindParam" if in order to find out if a parameter with a given name exists
426	>	and without raising and exception if it does not.
427	>
428	>	9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
429	>	consistency with SQL queries.
430	>
431	>	10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
432	>	When true, SQL statement parameter names are parsed case sensitive. Note for
433	>	TIBDataSet only applies to Select query.
434	>
435	>	11. IBEvents: removing a TIBEvent component from a form should no longer result in
436	>	an IDE exception.
437	>
438	>	12. LocalDBSupport: initial database creation should now work correctly
439	>	when the schema source is an sql file.
440	>
441	>	13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
442	>	when defined, this handler will be called by the internal TIBXScript during
443	>	initial database creation when the schema source is an sql file and may be used
444	>	to provide a visual indication of progress in console mode.
445	>
446	>	14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
447	>	to true while a new local database is being created and its schema populated.
448	>	Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
449	>	when the database is disconnected/connected during the create DB procedure.
450	>
451	>	15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
452	>	are now always ignored and replaced by the user name and password provided as
453	>	the login parameters for the TIBDatabase referenced from the TIBXScript. The
454	>	IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
455	>	completely ignored if this property is true.
456	>
457	>	16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
458	>	to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
459	>	ImageIndex and SelectImageIndex values on AddNode.
460	>
461	>	17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
462	>	read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
463	>	the same database connection.
464	>
465	>	18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
466	>	if provided, this should be an conditional SQL expression suitable for
467	>	including in an SQL Select statement "where" clause. If non-empty and the
468	>	"Filtered" property is true then the SQL expression provided as the value of
469	>	the "Filter" property is "ANDed" with any existing condition statement
470	>	in the SQL statement's "Where" clause.
471	>
472	>	If the "Filter" property is set at run time, the "Filtered" property is true
473	>	and the dataset is already open, then the dataset is closed and re-opened automatically.
474	>
475	>	The "Filter" condition may include IBX style parameters. In which case, their
476	>	value must be set by the dataset's "OnBeforeOpen" event handler.
477	>
478	>	This is a public property for TIBDataSet and TIBQuery query and intended for
479	>	use at run time.
480	>
481	>	Note: The property is a published property of TIBTable. The TIBTable functionality
482	>	is unaffected by this change.

486	>	1. Remove need to check for IsMultiThread by providing access to GUI timers via
487	>	IBGUIInterface. Note: master/detail delay timer does not apply to console
488	>	mode apps.
489	>
490	>	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
491	>	statement. This avoids problems if "Execute Block" is used as the Query.
492	>
493	>	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
494	>	internal SQL tokeniser routines.
495	>
496	>	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
497	>	as a select statement, with or without CTEs.
498	>
499	>	5. IBSQLParser: parser now recognises the "ROWS" clause.
500	>
501	>	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
502	>	internal SQL tokeniser routines.
503	>
504	>	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
505	>	being raised for valid set statements processed by a data formatter.
506	>
507	>	8. New published property for TIBDatabase and TIBXServicesConnection. This is
508	>	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
509	>	the path of the Firebird Library used by the database/services connection.
510	>
511	>	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
512	>	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
513	>	services connection.
514	>
515	>	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
516	>	or param name is not a valid SQL identifier.
517	>
518	>	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
519	>	view of whether the text box should be editable when no DataSource is specified.
520	>	TIBLookupComboEditBox has been updated to workaround this problem. As long as
521	>	ReadOnly is false, the text box is editable when no DataSource is specified.
522	>
523	>	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
524	>	the FBLIB environment variable. If you do not want to permit this then you
525	>	must modify the Register procedure in the design/IBDBReg.pas unit to remove

535	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
536	>	all previous copies of the IBX source code tree before installing this release.
537	>
538	>	The IBX packages used by most users have not changed, with one exception. The
539	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
540	>	to use the IBServices unit in your applications, please add the iblegacyServices
541	>	to the list of dependencies. To do this, open the Project Inspector and select
542	>	Add->New Requirement and select "ibLegacyServices" from the list of available
543	>	packages.
544	>
545	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
546	>	the IBServices unit providing what is intended to be a clearer and easier to
547	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
548	>	more information and the guide to "Firebird Service Management Using IBX".
549	>	As indicated above, the legacy services components are still available and
550	>	provided in a separate package. There is no need to update working applications
551	>	using the older versions except for an additional package dependency.
552	>
553	>	2. The IBX packages and source code tree have been re-organised in an attempt to
554	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
555	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
556	>	new set of IBX packages.
557	>
558	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
559	>	updated to use the new Services API components.
560	>
561	>	4. The iblocal package has been updated to use the new Services API components.
562	>
563	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
564	>	TIBXSecurityService. It had been wrongly classified in the previous version
565	>	as a per database configuration item. It is global to a server and hence
566	>	correctly positioned as part of the Security Package. In the DBAdmin example,
567	>	the setting has moved to the mappings page.
568	>
569	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
570	>	are ignored.
571	>
572	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
573	>	closed before the database is dropped. Before and After Disconnect event handlers
574	>	are also fired.
575	>
576	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
577	>	is started and not just the first time.
578	>
579	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
580	>	depenendency with comp type.
581	>
582	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
583	>
584	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
585	>	then this is recognised and not ignored.
586	>
587	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
588	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
589	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
590	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
591	>
592	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
593	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
594	>	counters for the select query. Note: stats accumulate after each fetch from
595	>	the database. To get total query cost after open, call the "Last" method
596	>	and then GetPerfStatistics.
597	>
598	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
599	>
600	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
601	>	in parenthesises.
602	>
603	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
604	>	SQL identifiers are always delimited by double quotes. If false, then they are
605	>	only delimited if the identifier is a reserved word, contains lower case or special
606	>	characters. Set this property to true to retain previous behaviour.
607	>
608	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
609	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
610	>
611	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
612	>	property MasterDetailDelay: integer {defaults to zero}
613	>
614	>	When non-zero and the dataset is a detail table referencing a master table
615	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
616	>	then a synchronisation delay is added (in milliseconds) between the master
617	>	row changing and the detail dataset being re-opened. If the master dataset
618	>	is scrolled before the delay expires then the delay is reset. This can be used
619	>	to avoid performance overheads when scrolling through a large master dataset.
620	>
621	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
622	>	chreads unit must be included in your project. TTimer is not used in order
623	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
624	>
625	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
626	>	with Extract Option eoDatabase.
627	>
628	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
629	>	When a deLayoutChanged event is reported on the ListSource dataset, the
630	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
631	>	relationship with the control's datasource (master).
632	>
633	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
634	>
635	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
636	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
637	>
638	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
639	>	DDL (Firebird 3 and later only).
640	>
641	>	22. TIBLookupComboBox Autocomplete Fixes:
642	>	i. Only appended text is now selected after autocomplete.
643	>	ii. Uppercase keys no longer ignored for autocomplete.
644	>	iii. Retain Prefix case is now honoured correctly.
645	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
646	>	before autocomplete performed. i.e. behaviour now the same as when
647	>	no DataSource assigned.
648	>
649	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
650	>	between SQL statements.
651	>
652	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
653	>	ObjectNames are converted to upper case before matching against metadata object
654	>	names, unless the objectname is delimited by double quotes, in which case, the
655	>	double quotes are removed and the remaining string is used (unmodified) to match
656	>	against the metadata object name.
657	>
658	>	If true then the ObjectName is used as is without modification and matched
659	>	against the metadata object name. No attempt is made to remove double quotes.
660	>
661	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
662	>	with eoTrigger, these extract types can be used to select only Database Triggers,
663	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
664	>
665	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
666	>	statement separate character is now reset to the default (';').
667	>
668	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
669	>
670	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
671	>	a commit or reconnect statement and instead activated only when next SQL statement
672	>	is executed.
673	>
674	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
675	>
676	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
677	>	converting statement to upper case.
678	>
679	>	31. TIBExtract: metadata comments now supported. New published property
680	>	IncludeMetaDataComments (default true). If true then metadata comments included
681	>	in extracted DDL. New Extract Object member eoComments. This may be used with
682	>	ExtractObject method to list all metadata comments.
683	>
684	>	32. TIBExtract: ListObjectNames method added.
685	>
686	>	33. Updated Database component editor to support additional connection string
687	>	types.

693	>	RELEASE.
694	>
695	>	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
696	>
697	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
698	>
699	>	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
700	>	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
701	>	information). However, this is also a very useful mechanism for returning updated computed by
702	>	column values. Values returned as a result of executing an Insert or Update statement
703	>	replace existing values in the current row for each corresponding column.
704	>
705	>	Previously, if a dataset's select query included read only (computed by) fields then
706	>	an automatic row refresh was performed after an insert or update query had been processed,
707	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
708	>	that an automatic refresh is no longer performed if an insert or update query contains
709	>	a returning clause that updates one or more fields on the current row. A full row
710	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
711	>	field values and the select query contains read only fields. Use of Insert/update
712	>	returning should be significantly more efficient than executing a refresh query.
713	>
714	>	This behaviour change is intended to be backwards compatible and there should be no need to change
715	>	existing programs, other than to improve performance by using the new capability.
716	>
717	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
718	>	they are called when the dataset row is being deleted, there is no value in
719	>	updating the current record from the query result. Instead, a new event handler
720	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
721	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
722	>	by the query. The event handler can then interrogate the query results and
723	>	perform whatever action is necessary. For example to confirm, to the user,
724	>	the deletion of a row with the returned values.
725	>
726	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
727	>	any Computed By or Identity Columns. The IBTables example has been updated to
728	>	illustrate the computation of the employee Full Name on update.
729	>
730	>	5. TIBTable: The GeneratorField property is now published.
731	>
732	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
733	>	When InsertSQL is generated, the Identity columns are not included in the list of values to
734	>	be inserted. A RETURNING clause is added to the insert statement to return the value of
735	>	each Identity column after the insert is executed.
736	>
737	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
738	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
739	>	Insert..Returning clause.
740	>
741	>	8. TIBGenerator: small performance improvement by not preparing query each time
742	>	a new value is generated.
743	>
744	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
745	>
746	>	10. Property editors will now sync table name to a System Table when "Include System
747	>	Tables" is selected and the query is for a System Table.
748	>
749	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
750	>	values are no longer converted to milliseconds from TDateTime and then back again
751	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
752	>
753	>	12. Property Editors handling of Stored Procedures.
754	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
755	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
756	>	query).
757	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
758	>
759	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
760	>	can be used to select a package. If non-empty, the stored procedure name is
761	>	expected to be a stored procedure defined in the specified package and the
762	>	generated SQL will be as required for a stored procedure located in a package.
763	>
764	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
765	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
766	>	which a stored procedure can be selected. With no package name selected, non-package
767	>	stored procedures are listed.
768	>
769	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
770	>	for password on reconnect.
771	>
772	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
773	>	and character set name.
774	>
775	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
776	>	DB info lookups"
777	>
778	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
779	>
780	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
781	>
782	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
783	>	parameters. This stops an exception being raised when the field cannot be
784	>	located in the record buffer.
785	>
786	>	21. Property Editors now automatically include System Tables when opened and when the query table
787	>	is a System Table.
788	>
789	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
790	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
791	>
792	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
793	>	add the SPB item isc_spb_expected_db. This names a database using
794	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
795	>	database. examples/services re-written to illustrate use of "expected_db".
796	>
797	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
798	>	This avoids truncated backups when the server returns a timeout (busy) response.
799	>
800	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
801	>
802	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
803	>	databasenames. These are respectively expanded to the local system's temp directory
804	>	(including trailing delimiter) or to a prescribed data directory (including
805	>	trailing delimiter). Under Unix systems the data directory is a hidden directory

885
886		1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
887		changes.
888
889	+	2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
890	+	Bug could result in truncated multi-byte character set values.
891	+
892	+	3. Changes consequential on moving fbintf character set utility functions from
893	+	IFirebirdAPI to IAttachment.
894	+
895	+	4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
896	+
897	+	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
898	+	results in autocomplete ignoring prefix text.
899	+
900	+	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
901	+	entering a new name into the text box.
902	+
903	+	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
904	+	Firebird rather than recomputing it.
905	+
906	+	8. Property Editor positioning tidy up: All IBX Property editors should now be
907	+	screen centre. Previously some were "poDesigned" which may be inappropriate
908	+	for multi monitor desktops.
909	+
910	+	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
911	+
912	+	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
913	+	a transaction and always reset the object.
914	+
915	+	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
916	+
917	+	13. TIBXScript: Allow for override of database filename in Create Database statements.
918	+
919	+	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
920	+	to a gbak format archive.
921	+
922	+	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
923	+
924	+	16. IBLocaldb: Drop database if error creating an empty database.
925	+
926	+	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
927	+	unless selected node not in current dataset.
928	+
929	+	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
930	+	to TIBCustomService, and IBlocalDB code tidy up.
931	+
932	+	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
933	+	behaviour due to uninitialised variable.
934	+
935	+	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
936	+	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
937	+
938	+	21. IBSQL: When Database changed ensure that all resources are freed.
939	+
940	+	22. IBCustomDataset: When database changed ensure that queries an unprepared.
941	+
942	+	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
943	+	* Line Wrap on SQL Token boundaries (on user command)
944	+	* auto-complete table names in drop down list of table names
945	+	* Double click on tablename or field name adds to SQL text
946	+
947	+	24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
948	+
949	+	25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
950	+	TVariantArray. Seems to avoid memory corruption in Windows (probably a
951	+	workaround for a problem in fpc 3.0.4 win64).
952	+
953	+	26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
954	+
955	+	27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
956	+

959		1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
#	Line 23 | Line 974 | IBX Change Log  version
974		that BindFields is called when the query is next activated. Avoids FieldName
975		not found error.
976
977	+	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
978	+	purpose and allows the programmer to define any action they want for Update, Insert
979	+	or Delete. This may be complex SQL (similar to a Trigger), application specific
980	+	filtering of updates, or use of statements such as Grant or Revoke instead of
981	+	normal DML. See User Manual for more information.
