1 + IBX Change Log  version (2.6-4 Build 14094) Sat, 21 Oct 2023 15:03:30 +0100
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 + IBX Change Log  version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
10 +
11 + 1. Update to calls to EInterbaseError to add default code page. Consequential
12 +   on change to fbintf.
13 +
14 + 2. Update some examples to replace test for null date with the NullDate constant
15 +   instead of zero. This is because Laz 3.0 changes the value of NullDate.
16 +
17 + IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
18 +
19 + 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
20 +   with later versions of fpc - later than 3.2.2.
21 +
22 + 2. IBUpdateSQL. update internal queries if parent dataset database changed.
23 +
24 + 3. IBUpdateSQL: Do not prepare an empty internal query.
25 +
26 + 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
27 +
28 + 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
29 +
30 + IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
31 +
32 + 1. Maintenance update of 2.6.0. This version is still at beta.
33 +
34 + 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
35 +   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
36 +
37 + 3. ibxscript: When parsing a store procedure or function with a variable name
38 +   enclosed in doublequotes, the double quotes are no longer removed.
39 +
40 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
41 +
42 + NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
43 +      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
44 +      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
45 +      ISSUES TO support@mwasoftware.co.uk
46 +
47 + 1. Complete rewrite of internal buffer management in order to improve performance
48 +   and maintainability. Highlights:
49 +
50 +   * Extending the size of the buffer pool no longer has to copy the entire record
51 +     cache. Instead, a new extent is simply added to the buffer pool.
52 +   * A memory to memory copy of each display buffer now is avoided when scolling the
53 +     dataset.
54 +   * A separate set of buffers is now used for calculated fields. This avoids
55 +     having to keep copies of calculated field values in the buffer cache.
56 +   * Compact bitmaps are used to record null status and need to refresh in each
57 +     buffer.
58 +   * Display buffer type changed from PChar to TRecordBuffer in line with change of
59 +     buffer type in FCL-DB.
60 +
61 + 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
62 +   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
63 +
64 + 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
65 +   If either or both of these flags are set at design time (using the fields editor)
66 +   then this forces a row refresh on respectively insert or update, or both, when the
67 +   corresponding field is not present in an SQL RETURNING clause.
68 +
69 + 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
70 +   maintainability and readability and to add identification of primary key fields.
71 +
72 + 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
73 +   as a refresh of the current row. However, this is different behaviour to that described
74 +   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
75 +   the dataset from the underlying database, and attempts to reposition the cursor on
76 +   the same record as it was". IBX now complies with the FPC definition of Refresh.
77 +
78 + 6. A progammatic Row Refresh should no longer be required.
79 +   Use Insert/Update... returning to refresh any fields that may change following an
80 +   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
81 +   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
82 +   for the field at Design Time to force a row refresh if not in the returning clause.
83 +
84 + 7. It should now be possible to insert a row into an empty unidirectional dataset.
85 +
86 + 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
87 +   This gives the number of buffers in the initial block for the buffer pool in
88 +   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
89 +   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
90 +   for small datasets.
91 +
92 + IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
93 +
94 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
95 +
96 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
97 +
98 + 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
99 +
100 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
101 +
102 + 1. TIBTransaction: new properties
103 +    property TransactionID: integer read GetTransactionID;
104 +    property IsReadOnly: boolean read GetIsReadOnly;
105 +    {published}
106 +    property TransactionName: string read FTransactionName write SetTransactionName;
107 +
108 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
109 +   Insert or Update...Returning. This allows blobs and arrays to be returned
110 +   by the statement.
111 +
112 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
113 +
114 + 4. TransactionName initialised to a newly generated GUID if empty.
115 +
116 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
117 +   for the fbintf package's journaling capability. TIBJournal is used to set the
118 +   file path and filename for the journal file and to Enabled (start journaling) and
119 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
120 +   more information, and comments in IBJournal.pas.
121 +
122 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
123 +
124 + 7. Bug fix: blob id no longer set to null on update when blob has not been
125 +   retrieved.
126 +
127 + 8. Row auto refreshed on update/insert if blob or array field updated and field
128 +   not in a returning clause.
129 +
130 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
131 +   buffer overhead and avoids problem when refresh query has a different column
132 +   count to select query i.e. incorrectly changing number of columns.
133 +
134 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
135 +
136 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
137 +    string. Note that the Version property returns an InterBase compatible version string.
138 +
139 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
140 +
141 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
142 +
143 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
144 +   This is for compatibility with Firebird 5 where Update...Returning can return
145 +   a cursor.
146 +
147 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
148 +
149 + 1. Add try-..except check when initially loading library in IDE. This should
150 + ensure that IDE continues to load even when a failure occurs in IBX load
151 + library.
152 +
153 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
154 +   hence will correctly detect end of the outer containing block when the block
155 +   contains a SELECT ... CASE ... END construct.
156 +
157 + 3. IBExtract: some further tidying up to remove extraneous white space.
158 +
159 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
160 +   errors when extra elements are added to DB.TFieldType.
161 +
162 + 5. IBUpdate: updated to reflect changes to ISQLParam.
163 +
164 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
165 +
166 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
167 +
168 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
169 +
170 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
171 +
172 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
173 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
174 +
175 + 2. TIBSQL: Batch Update/Insert support added.
176 +
177 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
178 +   is no longer automatically converted to upper case when it is syntactically a
179 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
180 +   as CREATE PROCEDURE "iCASE".
181 +
182 +   There could be a backwards compatibility issue when the StoredProcName was entered
183 +   manually at design time. That is not selected from the drop down list. If the
184 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
185 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
186 +   ensure that the value of the StoredProcName is all upper case, unless it was
187 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
188 +   quotes).
189 +
190 +   Note that when a stored procedure name was declared delimited in double quotes,
191 +   as in the first example above, the value of the StoredProcName property must not
192 +   include the delimiters (double quotes).
193 +
194 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
195 +   upgrade.conf was not found. This replaces silently ignoring the problem.
196 +
197 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
198 +   'Version.%.3d' and is used to generate the section header names (for a given
199 +   version no.) in the upgrade.conf file.
200 +
201 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
202 +
203 + 1. -c command line option added to fbsql example program. Used to set connection
204 +   character set.
205 +
206 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
207 +
208 + 1. Firebird 4 support added.
209 +
210 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
211 +   extended precision NUMERIC fields are supported.
212 +
213 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
214 +
215 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
216 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
217 +
218 + 5. IBExtract now supports FB4 enhancements:
219 +   - new data types as above
220 +   - Identity column extensions
221 +   - Default user role
222 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
223 +   - Internal Functions
224 +
225 + 6. IBExtract: new event: OnExtractLines.
226 +
227 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
228 +
229 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
230 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
231 +
232 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
233 +   format for rendering a time zone.
234 +
235 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
236 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
237 +
238 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
239 +    IIBGUIInterface and IIBTimerInf respectively.
240 +
241 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
242 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
243 +
244 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
245 +    truncated to its fixed character width rather than being right padded with
246 +    white space to the maximum data size.
247 +
248 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
249 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
250 +    also empty.
251 +
252 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
253 +
254 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
255 +    connect string. The database name is extracted from the connect string.
256 +
257 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
258 +
259 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
260 +
261 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
262 +    not being present as required.
263 +
264 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
265 +    version that can be customised to work with other database drivers.
266 +
267 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
268 +    unnecessary CR at end of line on Unix platforms.
269 +
270 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
271 +    seconds in order to reduce risk of message loss.
272 +
273 + 23. ISQLMonitor: read and write count statistics now available via:
274 +      property TIBSQLMonitor.ReadCount;
275 +      IIBSQLMonitorHook.GetWriteCount: integer;
276 +
277 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
278 +
279 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
280 +
281 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
282 +    number of UTF8 characters exceeds the string size then string is truncated
283 +    to the maximum string size. This is  usually a problem with fixed width columns
284 +    right padded with white space.
285 +
286 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
287 +    If SQLFiltered is set then when a dataset is opened, each line in the
288 +    SQLFilterParams property is assumed to be a SQL condition clause and
289 +    ANDed into the Where clause of the SQL Select statement provided as a
290 +    dataset property. Each such SQL condition thus acts as an additional filter
291 +    on the dataset.
292 +
293 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
294 +    side filters).
295 +
296 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
297 +   text matches complete entry.
298 +
299 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
300 +   dataset are active (avoids risk of access violation if master is inactive)
301 +
302 + 6. TIBEvents: Registered property can now be set at design time even if database not open
303 +
304 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
305 +   This should prevent "spillover" of events between sessions.
306 +
307 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
308 +   This should ensure that the internal buffer is set up correctly and avoids
309 +   a duplicate initial row.
310 +
311 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
312 +   That is, the DataSize should be the field size * character set width. The
313 +   value returned by DataSize is now the same as the Dataset buffer size reserved
314 +   for the field.
315 +
316 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
317 +
318 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
319 +    and vice-versa. This may result in an exception being raised (correctly) for
320 +    older programs when using dataset fields added to a form and the database has been
321 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
322 +    In such cases, the field needs to be deleted in the IDE fields editor and then
323 +    added back in.
324 +
325 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
326 +    false if query contains only white space and not just empty.
327 +
328 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
329 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
330 +    is cancelled.
331 +
332 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
333 +    called on a null field.
334 +
335 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
336 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
337 + set.
338 +
339 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
340 +    a cached update is applied and an exception is raised.
341 +
342 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
343 +
344 + 17. Console Mode Local Database support: backup/restore should now work correctly.
345 +
346 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
347 +    possible and an exception raised.
348 +
349 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
350 +    below this version no. and upgrade not possible.
351 +
352 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
353 +
354 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
355 +    not SQL Identifiers are now supported.
356 +
357 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
358 +    passed to the Firebird engine for execution.
359 +
360 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
361 +    is made to scroll back.
362 +
363 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
364 +
365 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
366 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
367 +
368 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
369 +   validated. If no match is found in the list of field names and the database has
370 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
371 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
372 +
373 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
374 +   with fpc 3.2.
375 +
376 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
377 +
378 +
379 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
380 +   and is used to override the default settings in the client side "firebird.conf" This
381 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
382 +   Each line of the string list should be a setting in the same format as "firebird.conf".
383 +   For example "WireCompression = true" in order to request wire compression on the client side.
384 +
385 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
386 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
387 +   also require a compatible setting in the server side "firebird.conf". For example
388 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
389 +   compression to be used.
390 +
391 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
392 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
393 +   ibx/examples/dbinfo for examples of how to display this information.
394 +
395 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
396 +   is a "convenience" property. If set the "WireCompression=true" is added to the
397 +   ConfigOverrides. If unchecked then this setting is removed.
398 +
399 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
400 +   not "INT64".
401 +
402 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
403 +   These are:
404 +    property TimestampFormat: string;
405 +    property DateFormat: string;
406 +    property TimeFormat: string;
407 +
408 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
409 +   DATETIME and TIME. The format strings use the standard FPC date/time format
410 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
411 +
412 +   If any of the above properties are set to an empty string, then the locale default
413 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
414 +   locale default is extended by appending '.zzz' to include milliseconds.
415 +
416 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
417 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
418 +
419 + 5. New published property for TIBCSVDataOut:
420 +     property QuoteStrings: boolean (default true)
421 +
422 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
423 +   used to delimit each and every string in the output.
424 +
425 + 6. New published properties for TIBCSVDataOut:
426 +    property FieldSeparator: string;
427 +    property HeaderSeparator: string;
428 +
429 +   Respectively, these provide the separator character(s) used to separate fields
430 +   in data and header rows. Both default to ','.
431 +
432 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
433 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
434 +    property OnFormatTextString;
435 +
436 +   This event handler can be used to process text strings before they are included
437 +   in the output e.g. to replace unprintable characters with alternative strings.
438 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
439 +
440 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
441 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
442 +   and without raising and exception if it does not.
443 +
444 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
445 +   consistency with SQL queries.
446 +
447 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
448 +    When true, SQL statement parameter names are parsed case sensitive. Note for
449 +    TIBDataSet only applies to Select query.
450 +
451 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
452 +    an IDE exception.
453 +
454 + 12. LocalDBSupport: initial database creation should now work correctly
455 +    when the schema source is an sql file.
456 +
457 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
458 +    when defined, this handler will be called by the internal TIBXScript during
459 +    initial database creation when the schema source is an sql file and may be used
460 +    to provide a visual indication of progress in console mode.
461 +
462 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
463 +    to true while a new local database is being created and its schema populated.
464 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
465 +    when the database is disconnected/connected during the create DB procedure.
466 +
467 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
468 +    are now always ignored and replaced by the user name and password provided as
469 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
470 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
471 +    completely ignored if this property is true.
472 +
473 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
474 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
475 +    ImageIndex and SelectImageIndex values on AddNode.
476 +
477 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
478 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
479 +    the same database connection.
480 +
481 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
482 +    if provided, this should be an conditional SQL expression suitable for
483 +    including in an SQL Select statement "where" clause. If non-empty and the
484 +    "Filtered" property is true then the SQL expression provided as the value of
485 +    the "Filter" property is "ANDed" with any existing condition statement
486 +    in the SQL statement's "Where" clause.
487 +
488 +    If the "Filter" property is set at run time, the "Filtered" property is true
489 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
490 +
491 +    The "Filter" condition may include IBX style parameters. In which case, their
492 +    value must be set by the dataset's "OnBeforeOpen" event handler.
493 +
494 +    This is a public property for TIBDataSet and TIBQuery query and intended for
495 +    use at run time.
496 +
497 +    Note: The property is a published property of TIBTable. The TIBTable functionality
498 +    is unaffected by this change.
499 +
500 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
501 +
502 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
503 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
504 +   mode apps.
505 +
506 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
507 +   statement. This avoids problems if "Execute Block" is used as the Query.
508 +
509 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
510 +   internal SQL tokeniser routines.
511 +
512 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
513 +   as a select statement, with or without CTEs.
514 +
515 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
516 +
517 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
518 +   internal SQL tokeniser routines.
519 +
520 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
521 +    being raised for valid set statements processed by a data formatter.
522 +
523 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
524 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
525 +   the path of the Firebird Library used by the database/services connection.
526 +
527 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
528 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
529 +   services connection.
530 +
531 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
532 +   or param name is not a valid SQL identifier.
533 +
534 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
535 +    view of whether the text box should be editable when no DataSource is specified.
536 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
537 +    ReadOnly is false, the text box is editable when no DataSource is specified.
538 +
539 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
540 +    the FBLIB environment variable. If you do not want to permit this then you
541 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
542 +    this setting.
