2 >
3 > 1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
4 >   if ApplyUpdates called before a cursor exists.
5 >
6 > 2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
7 >   creating the blob.
8 >
9 > 3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
10 >   issues with left over pointers to invalid internal buffers.
11 >
12 > 4. TIBCustomDataset.PrimaryKeys when used in InternalRefresh. when more than one
13 >   primary key is used by the dataset then the list of primary keys is now
14 >   properly separated by a ';'.
15 >
16 > 5. When refresh is called for a dataset without any primary keys (e.g. views and
17 >   stored procedures), the internal record number is now used to restore the cursor
18 >   following the refresh. However, it should be noted that cannot be 100% reliable.
19 >   The internal record number simply reflects the record fetch order and this can
20 >   change between successive queries if records are inserted or deleted by the
21 >   current or another user (if the read_committed transaction isolation level is used).
22 >
23 > 6. Inserting a record at the start of a grid and then resizing the grid should
24 >   no longer result in an apparent duplication of records in the grid. Note: this
25 >   was due to TDataset.SetCurrentRecord ignoring the bookmark flag (bfInserted). IBX
26 >   works around this by no longer using this bookmark flag value.
27 >
28 > 7. Inserting a record into an empty grid and then resizing the grid should
29 >   no longer result in an apparent duplication of records in the grid.
30 >
31 > 8. IBBufferedCursor. FCurrentRecordStatus now set correctly when selecting a
32 >   specific record number.
33 >
34 > 9. IBCustomDataset: Calls to AfterScroll during a Locate operation are now suppressed
35 >   until the end of the locate operation.
36 >
37 > 10.IBCustomDataset: Calls to BeforeScroll during a Locate operation are now suppressed.
38 >   BeforeScroll is called once before the locate operation.

40 > IBX Change Log  version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
41 >
42 > 1. Update to calls to EInterbaseError to add default code page. Consequential
43 >   on change to fbintf.
44 >
45 > 2. Update some examples to replace test for null date with the NullDate constant
46 >   instead of zero. This is because Laz 3.0 changes the value of NullDate.

48 > IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
49 >
50 > 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
51 >   with later versions of fpc - later than 3.2.2.
52 >
53 > 2. IBUpdateSQL. update internal queries if parent dataset database changed.
54 >
55 > 3. IBUpdateSQL: Do not prepare an empty internal query.
56 >
57 > 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
58 >
59 > 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
60 >
61 > IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
62 >
63 > 1. Maintenance update of 2.6.0. This version is still at beta.
64 >
65 > 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
66 >   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
67 >
68 > 3. ibxscript: When parsing a store procedure or function with a variable name
69 >   enclosed in doublequotes, the double quotes are no longer removed.
70 >
71 > IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
72 >
73 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
74 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
75 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
76 >      ISSUES TO support@mwasoftware.co.uk
77 >
78 > 1. Complete rewrite of internal buffer management in order to improve performance
79 >   and maintainability. Highlights:
80 >
81 >   * Extending the size of the buffer pool no longer has to copy the entire record
82 >     cache. Instead, a new extent is simply added to the buffer pool.
83 >   * A memory to memory copy of each display buffer now is avoided when scolling the
84 >     dataset.
85 >   * A separate set of buffers is now used for calculated fields. This avoids
86 >     having to keep copies of calculated field values in the buffer cache.
87 >   * Compact bitmaps are used to record null status and need to refresh in each
88 >     buffer.
89 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
90 >     buffer type in FCL-DB.
91 >
92 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
93 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
94 >
95 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
96 >   If either or both of these flags are set at design time (using the fields editor)
97 >   then this forces a row refresh on respectively insert or update, or both, when the
98 >   corresponding field is not present in an SQL RETURNING clause.
99 >
100 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
101 >   maintainability and readability and to add identification of primary key fields.
102 >
103 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
104 >   as a refresh of the current row. However, this is different behaviour to that described
105 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
106 >   the dataset from the underlying database, and attempts to reposition the cursor on
107 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
108 >
109 > 6. A progammatic Row Refresh should no longer be required.
110 >   Use Insert/Update... returning to refresh any fields that may change following an
111 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
112 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
113 >   for the field at Design Time to force a row refresh if not in the returning clause.
114 >
115 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
116 >
117 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
118 >   This gives the number of buffers in the initial block for the buffer pool in
119 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
120 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
121 >   for small datasets.
122 >
123 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
124 >
125 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
126 >
127 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
128 >
129 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
130 >
131 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
132 >
133 > 1. TIBTransaction: new properties
134 >    property TransactionID: integer read GetTransactionID;
135 >    property IsReadOnly: boolean read GetIsReadOnly;
136 >    {published}
137 >    property TransactionName: string read FTransactionName write SetTransactionName;
138 >
139 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
140 >   Insert or Update...Returning. This allows blobs and arrays to be returned
141 >   by the statement.
142 >
143 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
144 >
145 > 4. TransactionName initialised to a newly generated GUID if empty.
146 >
147 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
148 >   for the fbintf package's journaling capability. TIBJournal is used to set the
149 >   file path and filename for the journal file and to Enabled (start journaling) and
150 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
151 >   more information, and comments in IBJournal.pas.
152 >
153 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
154 >
155 > 7. Bug fix: blob id no longer set to null on update when blob has not been
156 >   retrieved.
157 >
158 > 8. Row auto refreshed on update/insert if blob or array field updated and field
159 >   not in a returning clause.
160 >
161 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
162 >   buffer overhead and avoids problem when refresh query has a different column
163 >   count to select query i.e. incorrectly changing number of columns.
164 >
165 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
166 >
167 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
168 >    string. Note that the Version property returns an InterBase compatible version string.
169 >
170 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
171 >
172 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
173 >
174 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
175 >   This is for compatibility with Firebird 5 where Update...Returning can return
176 >   a cursor.
177 >
178 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
179 >
180 > 1. Add try-..except check when initially loading library in IDE. This should
181 > ensure that IDE continues to load even when a failure occurs in IBX load
182 > library.
183 >
184 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
185 >   hence will correctly detect end of the outer containing block when the block
186 >   contains a SELECT ... CASE ... END construct.
187 >
188 > 3. IBExtract: some further tidying up to remove extraneous white space.
189 >
190 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
191 >   errors when extra elements are added to DB.TFieldType.
192 >
193 > 5. IBUpdate: updated to reflect changes to ISQLParam.
194 >
195 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
196 >
197 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
198 >
199 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
200 >
201 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
202 >
203 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
204 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
205 >
206 > 2. TIBSQL: Batch Update/Insert support added.
207 >
208 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
209 >   is no longer automatically converted to upper case when it is syntactically a
210 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
211 >   as CREATE PROCEDURE "iCASE".
212 >
213 >   There could be a backwards compatibility issue when the StoredProcName was entered
214 >   manually at design time. That is not selected from the drop down list. If the
215 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
216 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
217 >   ensure that the value of the StoredProcName is all upper case, unless it was
218 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
219 >   quotes).
220 >
221 >   Note that when a stored procedure name was declared delimited in double quotes,
222 >   as in the first example above, the value of the StoredProcName property must not
223 >   include the delimiters (double quotes).
224 >
225 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
226 >   upgrade.conf was not found. This replaces silently ignoring the problem.
227 >
228 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
229 >   'Version.%.3d' and is used to generate the section header names (for a given
230 >   version no.) in the upgrade.conf file.
231 >
232 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
233 >
234 > 1. -c command line option added to fbsql example program. Used to set connection
235 >   character set.
236 >
237 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
238 >
239 > 1. Firebird 4 support added.
240 >
241 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
242 >   extended precision NUMERIC fields are supported.
243 >
244 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
245 >
246 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
247 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
248 >
249 > 5. IBExtract now supports FB4 enhancements:
250 >   - new data types as above
251 >   - Identity column extensions
252 >   - Default user role
253 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
254 >   - Internal Functions
255 >
256 > 6. IBExtract: new event: OnExtractLines.
257 >
258 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
259 >
260 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
261 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
262 >
263 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
264 >   format for rendering a time zone.
265 >
266 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
267 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
268 >
269 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
270 >    IIBGUIInterface and IIBTimerInf respectively.
271 >
272 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
273 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
274 >
275 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
276 >    truncated to its fixed character width rather than being right padded with
277 >    white space to the maximum data size.
278 >
279 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
280 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
281 >    also empty.
282 >
283 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
284 >
285 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
286 >    connect string. The database name is extracted from the connect string.
287 >
288 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
289 >
290 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
291 >
292 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
293 >    not being present as required.
294 >
295 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
296 >    version that can be customised to work with other database drivers.
297 >
298 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
299 >    unnecessary CR at end of line on Unix platforms.
300 >
301 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
302 >    seconds in order to reduce risk of message loss.
303 >
304 > 23. ISQLMonitor: read and write count statistics now available via:
305 >      property TIBSQLMonitor.ReadCount;
306 >      IIBSQLMonitorHook.GetWriteCount: integer;
307 >
308 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
309 >
310 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
311 >
312 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
313 >    number of UTF8 characters exceeds the string size then string is truncated
314 >    to the maximum string size. This is  usually a problem with fixed width columns
315 >    right padded with white space.
316 >
317 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
318 >    If SQLFiltered is set then when a dataset is opened, each line in the
319 >    SQLFilterParams property is assumed to be a SQL condition clause and
320 >    ANDed into the Where clause of the SQL Select statement provided as a
321 >    dataset property. Each such SQL condition thus acts as an additional filter
322 >    on the dataset.
323 >
324 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
325 >    side filters).
326 >
327 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
328 >   text matches complete entry.
329 >
330 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
331 >   dataset are active (avoids risk of access violation if master is inactive)
332 >
333 > 6. TIBEvents: Registered property can now be set at design time even if database not open
334 >
335 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
336 >   This should prevent "spillover" of events between sessions.
337 >
338 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
339 >   This should ensure that the internal buffer is set up correctly and avoids
340 >   a duplicate initial row.
341 >
342 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
343 >   That is, the DataSize should be the field size * character set width. The
344 >   value returned by DataSize is now the same as the Dataset buffer size reserved
345 >   for the field.
346 >
347 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
348 >
349 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
350 >    and vice-versa. This may result in an exception being raised (correctly) for
351 >    older programs when using dataset fields added to a form and the database has been
352 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
353 >    In such cases, the field needs to be deleted in the IDE fields editor and then
354 >    added back in.
355 >
356 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
357 >    false if query contains only white space and not just empty.
358 >
359 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
360 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
361 >    is cancelled.
362 >
363 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
364 >    called on a null field.
365 >
366 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
367 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
368 > set.
369 >
370 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
371 >    a cached update is applied and an exception is raised.
372 >
373 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
374 >
375 > 17. Console Mode Local Database support: backup/restore should now work correctly.
376 >
377 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
378 >    possible and an exception raised.
379 >
380 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
381 >    below this version no. and upgrade not possible.

384 >
385 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
386 >    not SQL Identifiers are now supported.
387 >
388 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
389 >    passed to the Firebird engine for execution.
390 >
391 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
392 >    is made to scroll back.
393 >
394 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
395 >
396 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
397 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
398 >
399 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
400 >   validated. If no match is found in the list of field names and the database has
401 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
402 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
403 >
404 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
405 >   with fpc 3.2.

408 >
409 >
410 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
411 >   and is used to override the default settings in the client side "firebird.conf" This
412 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
413 >   Each line of the string list should be a setting in the same format as "firebird.conf".
414 >   For example "WireCompression = true" in order to request wire compression on the client side.
415 >
416 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
417 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
418 >   also require a compatible setting in the server side "firebird.conf". For example
419 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
420 >   compression to be used.
421 >
422 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
423 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
424 >   ibx/examples/dbinfo for examples of how to display this information.
425 >
426 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
427 >   is a "convenience" property. If set the "WireCompression=true" is added to the
428 >   ConfigOverrides. If unchecked then this setting is removed.
429 >
430 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
431 >   not "INT64".
432 >
433 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
434 >   These are:
435 >    property TimestampFormat: string;
436 >    property DateFormat: string;
437 >    property TimeFormat: string;
438 >
439 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
440 >   DATETIME and TIME. The format strings use the standard FPC date/time format
441 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
442 >
443 >   If any of the above properties are set to an empty string, then the locale default
444 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
445 >   locale default is extended by appending '.zzz' to include milliseconds.
446 >
447 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
448 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
449 >
450 > 5. New published property for TIBCSVDataOut:
451 >     property QuoteStrings: boolean (default true)
452 >
453 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
454 >   used to delimit each and every string in the output.
455 >
456 > 6. New published properties for TIBCSVDataOut:
457 >    property FieldSeparator: string;
458 >    property HeaderSeparator: string;
459 >
460 >   Respectively, these provide the separator character(s) used to separate fields
461 >   in data and header rows. Both default to ','.
462 >
463 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
464 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
465 >    property OnFormatTextString;
466 >
467 >   This event handler can be used to process text strings before they are included
468 >   in the output e.g. to replace unprintable characters with alternative strings.
469 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
470 >
471 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
472 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
473 >   and without raising and exception if it does not.
474 >
475 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
476 >   consistency with SQL queries.
477 >
478 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
479 >    When true, SQL statement parameter names are parsed case sensitive. Note for
480 >    TIBDataSet only applies to Select query.
481 >
482 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
483 >    an IDE exception.
484 >
485 > 12. LocalDBSupport: initial database creation should now work correctly
486 >    when the schema source is an sql file.
487 >
488 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
489 >    when defined, this handler will be called by the internal TIBXScript during
490 >    initial database creation when the schema source is an sql file and may be used
491 >    to provide a visual indication of progress in console mode.
492 >
493 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
494 >    to true while a new local database is being created and its schema populated.
495 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
496 >    when the database is disconnected/connected during the create DB procedure.
497 >
498 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
499 >    are now always ignored and replaced by the user name and password provided as
500 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
501 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
502 >    completely ignored if this property is true.
503 >
504 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
505 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
506 >    ImageIndex and SelectImageIndex values on AddNode.
507 >
508 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
509 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
510 >    the same database connection.
511 >
512 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
513 >    if provided, this should be an conditional SQL expression suitable for
514 >    including in an SQL Select statement "where" clause. If non-empty and the
515 >    "Filtered" property is true then the SQL expression provided as the value of
516 >    the "Filter" property is "ANDed" with any existing condition statement
517 >    in the SQL statement's "Where" clause.
518 >
519 >    If the "Filter" property is set at run time, the "Filtered" property is true
520 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
521 >
522 >    The "Filter" condition may include IBX style parameters. In which case, their
523 >    value must be set by the dataset's "OnBeforeOpen" event handler.
524 >
525 >    This is a public property for TIBDataSet and TIBQuery query and intended for
526 >    use at run time.
527 >
528 >    Note: The property is a published property of TIBTable. The TIBTable functionality
529 >    is unaffected by this change.
530 >
531 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
532 >
533 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
534 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
535 >   mode apps.
536 >
537 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
538 >   statement. This avoids problems if "Execute Block" is used as the Query.
539 >
540 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
541 >   internal SQL tokeniser routines.
542 >
543 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
544 >   as a select statement, with or without CTEs.
545 >
546 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
547 >
548 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
549 >   internal SQL tokeniser routines.
550 >
551 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
552 >    being raised for valid set statements processed by a data formatter.
553 >
554 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
555 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
556 >   the path of the Firebird Library used by the database/services connection.
557 >
558 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
559 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
560 >   services connection.
561 >
562 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
563 >   or param name is not a valid SQL identifier.
564 >
565 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
566 >    view of whether the text box should be editable when no DataSource is specified.
567 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
568 >    ReadOnly is false, the text box is editable when no DataSource is specified.
569 >
570 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
571 >    the FBLIB environment variable. If you do not want to permit this then you
572 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
573 >    this setting.
574 >
575 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
576 >
577 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
578 >   Utf8EscapeControlChars
579 >
580 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
581 >
582 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
583 > all previous copies of the IBX source code tree before installing this release.
584 >
585 > The IBX packages used by most users have not changed, with one exception. The
586 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
587 > to use the IBServices unit in your applications, please add the iblegacyServices
588 > to the list of dependencies. To do this, open the Project Inspector and select
589 > Add->New Requirement and select "ibLegacyServices" from the list of available
590 > packages.
591 >
592 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
593 >   the IBServices unit providing what is intended to be a clearer and easier to
594 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
595 >   more information and the guide to "Firebird Service Management Using IBX".
596 >   As indicated above, the legacy services components are still available and
597 >   provided in a separate package. There is no need to update working applications
598 >   using the older versions except for an additional package dependency.
599 >
600 > 2. The IBX packages and source code tree have been re-organised in an attempt to
601 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
602 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
603 >   new set of IBX packages.
604 >
605 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
606 >   updated to use the new Services API components.
607 >
608 > 4. The iblocal package has been updated to use the new Services API components.
609 >
610 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
611 >   TIBXSecurityService. It had been wrongly classified in the previous version
612 >   as a per database configuration item. It is global to a server and hence
613 >   correctly positioned as part of the Security Package. In the DBAdmin example,
614 >   the setting has moved to the mappings page.
615 >
616 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
617 >   are ignored.
618 >
619 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
620 >   closed before the database is dropped. Before and After Disconnect event handlers
621 >   are also fired.
622 >
623 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
624 >   is started and not just the first time.
625 >
626 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
627 >   depenendency with comp type.
628 >
629 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
630 >
631 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
632 >    then this is recognised and not ignored.
633 >
634 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
635 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
636 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
637 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
638 >
639 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
640 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
641 >    counters for the select query. Note: stats accumulate after each fetch from
642 >    the database. To get total query cost after open, call the "Last" method
643 >    and then GetPerfStatistics.
644 >
645 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
646 >
647 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
648 >    in parenthesises.
649 >
650 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
651 >    SQL identifiers are always delimited by double quotes. If false, then they are
652 >    only delimited if the identifier is a reserved word, contains lower case or special
653 >    characters. Set this property to true to retain previous behaviour.
654 >
655 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
656 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
657 >
658 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
659 >       property MasterDetailDelay: integer {defaults to zero}
660 >
661 >    When non-zero and the dataset is a detail table referencing a master table
662 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
663 >    then a synchronisation delay is added (in milliseconds) between the master
664 >    row changing and the detail dataset being re-opened. If the master dataset
665 >    is scrolled before the delay expires then the delay is reset. This can be used
666 >    to avoid performance overheads when scrolling through a large master dataset.
667 >
668 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
669 >    chreads unit must be included in your project. TTimer is not used in order
670 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
671 >
672 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
673 >    with Extract Option eoDatabase.
674 >
675 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
676 >    When a deLayoutChanged event is reported on the ListSource dataset, the
677 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
678 >    relationship with the control's datasource (master).
679 >
680 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
681 >
682 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
683 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
684 >
685 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
686 >    DDL (Firebird 3 and later only).
687 >
688 > 22. TIBLookupComboBox Autocomplete Fixes:
689 >    i. Only appended text is now selected after autocomplete.
690 >    ii. Uppercase keys no longer ignored for autocomplete.
691 >    iii. Retain Prefix case is now honoured correctly.
692 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
693 >        before autocomplete performed. i.e. behaviour now the same as when
694 >        no DataSource assigned.
695 >
696 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
697 >    between SQL statements.
698 >
699 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
700 >    ObjectNames are converted to upper case before matching against metadata object
701 >    names, unless the objectname is delimited by double quotes, in which case, the
702 >    double quotes are removed and the remaining string is used (unmodified) to match
703 >    against the metadata object name.
704 >
705 >    If true then the ObjectName is used as is without modification and matched
706 >    against the metadata object name. No attempt is made to remove double quotes.
707 >
708 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
709 >    with eoTrigger, these extract types can be used to select only Database Triggers,
710 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
711 >
712 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
713 >    statement separate character is now reset to the default (';').
714 >
715 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
716 >
717 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
718 >    a commit or reconnect statement and instead activated only when next SQL statement
719 >    is executed.
720 >
721 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
722 >
723 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
724 >    converting statement to upper case.
725 >
726 > 31. TIBExtract: metadata comments now supported. New published property
727 >    IncludeMetaDataComments (default true). If true then metadata comments included
728 >    in extracted DDL. New Extract Object member eoComments. This may be used with
729 >    ExtractObject method to list all metadata comments.
730 >
731 > 32. TIBExtract: ListObjectNames method added.
732 >
733 > 33. Updated Database component editor to support additional connection string
734 >    types.
735 >
