12 >
13 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
14 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
15 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
16 >      ISSUES TO support@mwasoftware.co.uk
17 >
18 > 1. Complete rewrite of internal buffer management in order to improve performance
19 >   and maintainability. Highlights:
20 >
21 >   * Extending the size of the buffer pool no longer has to copy the entire record
22 >     cache. Instead, a new extent is simply added to the buffer pool.
23 >   * A memory to memory copy of each display buffer now is avoided when scolling the
24 >     dataset.
25 >   * A separate set of buffers is now used for calculated fields. This avoids
26 >     having to keep copies of calculated field values in the buffer cache.
27 >   * Compact bitmaps are used to record null status and need to refresh in each
28 >     buffer.
29 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
30 >     buffer type in FCL-DB.
31 >
32 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
33 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
34 >
35 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
36 >   If either or both of these flags are set at design time (using the fields editor)
37 >   then this forces a row refresh on respectively insert or update, or both, when the
38 >   corresponding field is not present in an SQL RETURNING clause.
39 >
40 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
41 >   maintainability and readability and to add identification of primary key fields.
42 >
43 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
44 >   as a refresh of the current row. However, this is different behaviour to that described
45 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
46 >   the dataset from the underlying database, and attempts to reposition the cursor on
47 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
48 >
49 > 6. A progammatic Row Refresh should no longer be required.
50 >   Use Insert/Update... returning to refresh any fields that may change following an
51 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
52 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
53 >   for the field at Design Time to force a row refresh if not in the returning clause.
54 >
55 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
56 >
57 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
58 >   This gives the number of buffers in the initial block for the buffer pool in
59 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
60 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
61 >   for small datasets.
62 >
63 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
64 >
65 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
66 >
67 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
68 >
69 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
70 >
71 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
72 >
73 > 1. TIBTransaction: new properties
74 >    property TransactionID: integer read GetTransactionID;
75 >    property IsReadOnly: boolean read GetIsReadOnly;
76 >    {published}
77 >    property TransactionName: string read FTransactionName write SetTransactionName;
78 >
79 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
80 >   Insert or Update...Returning. This allows blobs and arrays to be returned
81 >   by the statement.
82 >
83 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
84 >
85 > 4. TransactionName initialised to a newly generated GUID if empty.
86 >
87 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
88 >   for the fbintf package's journaling capability. TIBJournal is used to set the
89 >   file path and filename for the journal file and to Enabled (start journaling) and
90 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
91 >   more information, and comments in IBJournal.pas.
92 >
93 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
94 >
95 > 7. Bug fix: blob id no longer set to null on update when blob has not been
96 >   retrieved.
97 >
98 > 8. Row auto refreshed on update/insert if blob or array field updated and field
99 >   not in a returning clause.
100 >
101 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
102 >   buffer overhead and avoids problem when refresh query has a different column
103 >   count to select query i.e. incorrectly changing number of columns.
104 >
105 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
106 >
107 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
108 >    string. Note that the Version property returns an InterBase compatible version string.
109 >
110 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
111 >
112 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
113 >
114 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
115 >   This is for compatibility with Firebird 5 where Update...Returning can return
116 >   a cursor.
117 >
118 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
119 >
120 > 1. Add try-..except check when initially loading library in IDE. This should
121 > ensure that IDE continues to load even when a failure occurs in IBX load
122 > library.
123 >
124 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
125 >   hence will correctly detect end of the outer containing block when the block
126 >   contains a SELECT ... CASE ... END construct.
127 >
128 > 3. IBExtract: some further tidying up to remove extraneous white space.
129 >
130 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
131 >   errors when extra elements are added to DB.TFieldType.
132 >
133 > 5. IBUpdate: updated to reflect changes to ISQLParam.
134 >
135 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
136 >
137 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
138 >
139 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
140 >
141 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
142 >
143 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
144 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
145 >
146 > 2. TIBSQL: Batch Update/Insert support added.
147 >
148 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
149 >   is no longer automatically converted to upper case when it is syntactically a
150 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
151 >   as CREATE PROCEDURE "iCASE".
152 >
153 >   There could be a backwards compatibility issue when the StoredProcName was entered
154 >   manually at design time. That is not selected from the drop down list. If the
155 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
156 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
157 >   ensure that the value of the StoredProcName is all upper case, unless it was
158 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
159 >   quotes).
160 >
161 >   Note that when a stored procedure name was declared delimited in double quotes,
162 >   as in the first example above, the value of the StoredProcName property must not
163 >   include the delimiters (double quotes).
164 >
165 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
166 >   upgrade.conf was not found. This replaces silently ignoring the problem.
167 >
168 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
169 >   'Version.%.3d' and is used to generate the section header names (for a given
170 >   version no.) in the upgrade.conf file.
171 >
172 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
173 >
174 > 1. -c command line option added to fbsql example program. Used to set connection
175 >   character set.
176 >
177 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
178 >
179 > 1. Firebird 4 support added.
180 >
181 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
182 >   extended precision NUMERIC fields are supported.
183 >
184 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
185 >
186 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
187 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
188 >
189 > 5. IBExtract now supports FB4 enhancements:
190 >   - new data types as above
191 >   - Identity column extensions
192 >   - Default user role
193 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
194 >   - Internal Functions
195 >
196 > 6. IBExtract: new event: OnExtractLines.
197 >
198 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
199 >
200 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
201 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
202 >
203 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
204 >   format for rendering a time zone.
205 >
206 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
207 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
208 >
209 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
210 >    IIBGUIInterface and IIBTimerInf respectively.
211 >
212 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
213 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
214 >
215 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
216 >    truncated to its fixed character width rather than being right padded with
217 >    white space to the maximum data size.
218 >
219 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
220 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
221 >    also empty.
222 >
223 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
224 >
225 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
226 >    connect string. The database name is extracted from the connect string.
227 >
228 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
229 >
230 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
231 >
232 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
233 >    not being present as required.
234 >
235 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
236 >    version that can be customised to work with other database drivers.
237 >
238 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
239 >    unnecessary CR at end of line on Unix platforms.
240 >
241 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
242 >    seconds in order to reduce risk of message loss.
243 >
244 > 23. ISQLMonitor: read and write count statistics now available via:
245 >      property TIBSQLMonitor.ReadCount;
246 >      IIBSQLMonitorHook.GetWriteCount: integer;
247 >
248 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
249 >
250 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
251 >
252 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
253 >    number of UTF8 characters exceeds the string size then string is truncated
254 >    to the maximum string size. This is  usually a problem with fixed width columns
255 >    right padded with white space.
256 >
257 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
258 >    If SQLFiltered is set then when a dataset is opened, each line in the
259 >    SQLFilterParams property is assumed to be a SQL condition clause and
260 >    ANDed into the Where clause of the SQL Select statement provided as a
261 >    dataset property. Each such SQL condition thus acts as an additional filter
262 >    on the dataset.
263 >
264 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
265 >    side filters).
266 >
267 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
268 >   text matches complete entry.
269 >
270 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
271 >   dataset are active (avoids risk of access violation if master is inactive)
272 >
273 > 6. TIBEvents: Registered property can now be set at design time even if database not open
274 >
275 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
276 >   This should prevent "spillover" of events between sessions.
277 >
278 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
279 >   This should ensure that the internal buffer is set up correctly and avoids
280 >   a duplicate initial row.
281 >
282 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
283 >   That is, the DataSize should be the field size * character set width. The
284 >   value returned by DataSize is now the same as the Dataset buffer size reserved
285 >   for the field.
286 >
287 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
288 >
289 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
290 >    and vice-versa. This may result in an exception being raised (correctly) for
291 >    older programs when using dataset fields added to a form and the database has been
292 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
293 >    In such cases, the field needs to be deleted in the IDE fields editor and then
294 >    added back in.
295 >
296 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
297 >    false if query contains only white space and not just empty.
298 >
299 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
300 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
301 >    is cancelled.
302 >
303 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
304 >    called on a null field.
305 >
306 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
307 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
308 > set.
309 >
310 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
311 >    a cached update is applied and an exception is raised.
312 >
313 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
314 >
315 > 17. Console Mode Local Database support: backup/restore should now work correctly.
316 >
317 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
318 >    possible and an exception raised.
319 >
320 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
321 >    below this version no. and upgrade not possible.
322 >
323 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
324 >
325 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
326 >    not SQL Identifiers are now supported.
327 >
328 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
329 >    passed to the Firebird engine for execution.
330 >
331 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
332 >    is made to scroll back.
333 >
334 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
335 >
336 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
337 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
338 >
339 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
340 >   validated. If no match is found in the list of field names and the database has
341 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
342 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
343 >
344 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
345 >   with fpc 3.2.
346 >
347 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
348 >
349 >
350 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
351 >   and is used to override the default settings in the client side "firebird.conf" This
352 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
353 >   Each line of the string list should be a setting in the same format as "firebird.conf".
354 >   For example "WireCompression = true" in order to request wire compression on the client side.
355 >
356 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
357 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
358 >   also require a compatible setting in the server side "firebird.conf". For example
359 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
360 >   compression to be used.
361 >
362 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
363 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
364 >   ibx/examples/dbinfo for examples of how to display this information.
365 >
366 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
367 >   is a "convenience" property. If set the "WireCompression=true" is added to the
368 >   ConfigOverrides. If unchecked then this setting is removed.
369 >
370 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
371 >   not "INT64".
372 >
373 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
374 >   These are:
375 >    property TimestampFormat: string;
376 >    property DateFormat: string;
377 >    property TimeFormat: string;
378 >
379 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
380 >   DATETIME and TIME. The format strings use the standard FPC date/time format
381 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
382 >
383 >   If any of the above properties are set to an empty string, then the locale default
384 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
385 >   locale default is extended by appending '.zzz' to include milliseconds.
386 >
387 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
388 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
389 >
390 > 5. New published property for TIBCSVDataOut:
391 >     property QuoteStrings: boolean (default true)
392 >
393 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
394 >   used to delimit each and every string in the output.
395 >
396 > 6. New published properties for TIBCSVDataOut:
397 >    property FieldSeparator: string;
398 >    property HeaderSeparator: string;
399 >
400 >   Respectively, these provide the separator character(s) used to separate fields
401 >   in data and header rows. Both default to ','.
402 >
403 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
404 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
405 >    property OnFormatTextString;
406 >
407 >   This event handler can be used to process text strings before they are included
408 >   in the output e.g. to replace unprintable characters with alternative strings.
409 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
410 >
411 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
412 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
413 >   and without raising and exception if it does not.
414 >
415 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
416 >   consistency with SQL queries.
417 >
418 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
419 >    When true, SQL statement parameter names are parsed case sensitive. Note for
420 >    TIBDataSet only applies to Select query.
421 >
422 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
423 >    an IDE exception.
424 >
425 > 12. LocalDBSupport: initial database creation should now work correctly
426 >    when the schema source is an sql file.
427 >
428 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
429 >    when defined, this handler will be called by the internal TIBXScript during
430 >    initial database creation when the schema source is an sql file and may be used
431 >    to provide a visual indication of progress in console mode.
432 >
433 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
434 >    to true while a new local database is being created and its schema populated.
435 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
436 >    when the database is disconnected/connected during the create DB procedure.
437 >
438 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
439 >    are now always ignored and replaced by the user name and password provided as
440 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
441 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
442 >    completely ignored if this property is true.
443 >
444 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
445 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
446 >    ImageIndex and SelectImageIndex values on AddNode.
447 >
448 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
449 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
450 >    the same database connection.
451 >
452 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
453 >    if provided, this should be an conditional SQL expression suitable for
454 >    including in an SQL Select statement "where" clause. If non-empty and the
455 >    "Filtered" property is true then the SQL expression provided as the value of
456 >    the "Filter" property is "ANDed" with any existing condition statement
457 >    in the SQL statement's "Where" clause.
458 >
459 >    If the "Filter" property is set at run time, the "Filtered" property is true
460 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
461 >
462 >    The "Filter" condition may include IBX style parameters. In which case, their
463 >    value must be set by the dataset's "OnBeforeOpen" event handler.
464 >
465 >    This is a public property for TIBDataSet and TIBQuery query and intended for
466 >    use at run time.
467 >
468 >    Note: The property is a published property of TIBTable. The TIBTable functionality
469 >    is unaffected by this change.
470 >
471 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
472 >
473 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
474 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
475 >   mode apps.
476 >
477 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
478 >   statement. This avoids problems if "Execute Block" is used as the Query.
479 >
480 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
481 >   internal SQL tokeniser routines.
482 >
483 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
484 >   as a select statement, with or without CTEs.
485 >
486 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
487 >
488 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
489 >   internal SQL tokeniser routines.
490 >
491 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
492 >    being raised for valid set statements processed by a data formatter.
493 >
494 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
495 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
496 >   the path of the Firebird Library used by the database/services connection.
497 >
498 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
499 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
500 >   services connection.
501 >
502 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
503 >   or param name is not a valid SQL identifier.
504 >
505 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
506 >    view of whether the text box should be editable when no DataSource is specified.
507 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
508 >    ReadOnly is false, the text box is editable when no DataSource is specified.
509 >
510 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
511 >    the FBLIB environment variable. If you do not want to permit this then you
512 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
513 >    this setting.
514 >
515 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
516 >
517 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
518 >   Utf8EscapeControlChars
519 >
520 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
521 >
522 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
523 > all previous copies of the IBX source code tree before installing this release.
524 >
525 > The IBX packages used by most users have not changed, with one exception. The
526 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
527 > to use the IBServices unit in your applications, please add the iblegacyServices
528 > to the list of dependencies. To do this, open the Project Inspector and select
529 > Add->New Requirement and select "ibLegacyServices" from the list of available
530 > packages.
531 >
532 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
533 >   the IBServices unit providing what is intended to be a clearer and easier to
534 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
535 >   more information and the guide to "Firebird Service Management Using IBX".
536 >   As indicated above, the legacy services components are still available and
537 >   provided in a separate package. There is no need to update working applications
538 >   using the older versions except for an additional package dependency.
539 >
540 > 2. The IBX packages and source code tree have been re-organised in an attempt to
541 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
542 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
543 >   new set of IBX packages.
544 >
545 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
546 >   updated to use the new Services API components.
547 >
548 > 4. The iblocal package has been updated to use the new Services API components.
549 >
550 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
551 >   TIBXSecurityService. It had been wrongly classified in the previous version
552 >   as a per database configuration item. It is global to a server and hence
553 >   correctly positioned as part of the Security Package. In the DBAdmin example,
554 >   the setting has moved to the mappings page.
555 >
556 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
557 >   are ignored.
558 >
559 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
560 >   closed before the database is dropped. Before and After Disconnect event handlers
561 >   are also fired.
562 >
563 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
564 >   is started and not just the first time.
565 >
566 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
567 >   depenendency with comp type.
568 >
569 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
570 >
571 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
572 >    then this is recognised and not ignored.
573 >
574 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
575 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
576 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
577 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
578 >
579 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
580 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
581 >    counters for the select query. Note: stats accumulate after each fetch from
582 >    the database. To get total query cost after open, call the "Last" method
583 >    and then GetPerfStatistics.
584 >
585 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
586 >
587 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
588 >    in parenthesises.
589 >
590 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
591 >    SQL identifiers are always delimited by double quotes. If false, then they are
592 >    only delimited if the identifier is a reserved word, contains lower case or special
593 >    characters. Set this property to true to retain previous behaviour.
594 >
595 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
596 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
597 >
598 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
599 >       property MasterDetailDelay: integer {defaults to zero}
600 >
601 >    When non-zero and the dataset is a detail table referencing a master table
602 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
603 >    then a synchronisation delay is added (in milliseconds) between the master
604 >    row changing and the detail dataset being re-opened. If the master dataset
605 >    is scrolled before the delay expires then the delay is reset. This can be used
606 >    to avoid performance overheads when scrolling through a large master dataset.
607 >
608 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
609 >    chreads unit must be included in your project. TTimer is not used in order
610 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
611 >
612 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
613 >    with Extract Option eoDatabase.
614 >
615 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
616 >    When a deLayoutChanged event is reported on the ListSource dataset, the
617 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
618 >    relationship with the control's datasource (master).
619 >
620 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
621 >
622 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
623 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
624 >
625 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
626 >    DDL (Firebird 3 and later only).
627 >
628 > 22. TIBLookupComboBox Autocomplete Fixes:
629 >    i. Only appended text is now selected after autocomplete.
630 >    ii. Uppercase keys no longer ignored for autocomplete.
631 >    iii. Retain Prefix case is now honoured correctly.
632 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
633 >        before autocomplete performed. i.e. behaviour now the same as when
634 >        no DataSource assigned.
635 >
636 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
637 >    between SQL statements.
638 >
639 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
640 >    ObjectNames are converted to upper case before matching against metadata object
641 >    names, unless the objectname is delimited by double quotes, in which case, the
642 >    double quotes are removed and the remaining string is used (unmodified) to match
643 >    against the metadata object name.
644 >
645 >    If true then the ObjectName is used as is without modification and matched
646 >    against the metadata object name. No attempt is made to remove double quotes.
647 >
648 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
649 >    with eoTrigger, these extract types can be used to select only Database Triggers,
650 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
651 >
652 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
653 >    statement separate character is now reset to the default (';').
654 >
655 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
656 >
657 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
658 >    a commit or reconnect statement and instead activated only when next SQL statement
659 >    is executed.
660 >
661 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
662 >
663 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
664 >    converting statement to upper case.
665 >
666 > 31. TIBExtract: metadata comments now supported. New published property
667 >    IncludeMetaDataComments (default true). If true then metadata comments included
668 >    in extracted DDL. New Extract Object member eoComments. This may be used with
669 >    ExtractObject method to list all metadata comments.
670 >
671 > 32. TIBExtract: ListObjectNames method added.
672 >
673 > 33. Updated Database component editor to support additional connection string
674 >    types.
675 >
676 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
677 >
678 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
679 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
680 > RELEASE.
681 >
682 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
