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.

39 > 1. Update to calls to EInterbaseError to add default code page. Consequential
40 >   on change to fbintf.
41 >
42 > 2. Update some examples to replace test for null date with the NullDate constant
43 >   instead of zero. This is because Laz 3.0 changes the value of NullDate.

47 > 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
48 >   with later versions of fpc - later than 3.2.2.
49 >
50 > 2. IBUpdateSQL. update internal queries if parent dataset database changed.
51 >
52 > 3. IBUpdateSQL: Do not prepare an empty internal query.

69 >
70 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
71 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
72 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
73 >      ISSUES TO support@mwasoftware.co.uk
74 >
75 > 1. Complete rewrite of internal buffer management in order to improve performance
76 >   and maintainability. Highlights:
77 >
78 >   * Extending the size of the buffer pool no longer has to copy the entire record
79 >     cache. Instead, a new extent is simply added to the buffer pool.
80 >   * A memory to memory copy of each display buffer now is avoided when scolling the
81 >     dataset.
82 >   * A separate set of buffers is now used for calculated fields. This avoids
83 >     having to keep copies of calculated field values in the buffer cache.
84 >   * Compact bitmaps are used to record null status and need to refresh in each
85 >     buffer.
86 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
87 >     buffer type in FCL-DB.
88 >
89 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
90 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
91 >
92 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
93 >   If either or both of these flags are set at design time (using the fields editor)
94 >   then this forces a row refresh on respectively insert or update, or both, when the
95 >   corresponding field is not present in an SQL RETURNING clause.
96 >
97 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
98 >   maintainability and readability and to add identification of primary key fields.
99 >
100 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
101 >   as a refresh of the current row. However, this is different behaviour to that described
102 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
103 >   the dataset from the underlying database, and attempts to reposition the cursor on
104 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
105 >
106 > 6. A progammatic Row Refresh should no longer be required.
107 >   Use Insert/Update... returning to refresh any fields that may change following an
108 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
109 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
110 >   for the field at Design Time to force a row refresh if not in the returning clause.
111 >
112 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
113 >
114 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
115 >   This gives the number of buffers in the initial block for the buffer pool in
116 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
117 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
118 >   for small datasets.
119 >
120 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
121 >
122 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
123 >
124 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
125 >
126 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
127 >
128 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
129 >
130 > 1. TIBTransaction: new properties
131 >    property TransactionID: integer read GetTransactionID;
132 >    property IsReadOnly: boolean read GetIsReadOnly;
133 >    {published}
134 >    property TransactionName: string read FTransactionName write SetTransactionName;
135 >
136 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
137 >   Insert or Update...Returning. This allows blobs and arrays to be returned
138 >   by the statement.
139 >
140 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
141 >
142 > 4. TransactionName initialised to a newly generated GUID if empty.
143 >
144 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
145 >   for the fbintf package's journaling capability. TIBJournal is used to set the
146 >   file path and filename for the journal file and to Enabled (start journaling) and
147 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
148 >   more information, and comments in IBJournal.pas.
149 >
150 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
151 >
152 > 7. Bug fix: blob id no longer set to null on update when blob has not been
153 >   retrieved.
154 >
155 > 8. Row auto refreshed on update/insert if blob or array field updated and field
156 >   not in a returning clause.
157 >
158 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
159 >   buffer overhead and avoids problem when refresh query has a different column
160 >   count to select query i.e. incorrectly changing number of columns.
161 >
162 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
163 >
164 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
165 >    string. Note that the Version property returns an InterBase compatible version string.
166 >
167 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
168 >
169 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
170 >
171 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
172 >   This is for compatibility with Firebird 5 where Update...Returning can return
173 >   a cursor.
174 >
175 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
176 >
177 > 1. Add try-..except check when initially loading library in IDE. This should
178 > ensure that IDE continues to load even when a failure occurs in IBX load
179 > library.
180 >
181 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
182 >   hence will correctly detect end of the outer containing block when the block
183 >   contains a SELECT ... CASE ... END construct.
184 >
185 > 3. IBExtract: some further tidying up to remove extraneous white space.
186 >
187 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
188 >   errors when extra elements are added to DB.TFieldType.
189 >
190 > 5. IBUpdate: updated to reflect changes to ISQLParam.
191 >
192 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
193 >
194 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
195 >
196 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
197 >
198 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
199 >
200 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
201 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
202 >
203 > 2. TIBSQL: Batch Update/Insert support added.
204 >
205 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
206 >   is no longer automatically converted to upper case when it is syntactically a
207 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
208 >   as CREATE PROCEDURE "iCASE".
209 >
210 >   There could be a backwards compatibility issue when the StoredProcName was entered
211 >   manually at design time. That is not selected from the drop down list. If the
212 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
213 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
214 >   ensure that the value of the StoredProcName is all upper case, unless it was
215 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
216 >   quotes).
217 >
218 >   Note that when a stored procedure name was declared delimited in double quotes,
219 >   as in the first example above, the value of the StoredProcName property must not
220 >   include the delimiters (double quotes).
221 >
222 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
223 >   upgrade.conf was not found. This replaces silently ignoring the problem.
224 >
225 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
226 >   'Version.%.3d' and is used to generate the section header names (for a given
227 >   version no.) in the upgrade.conf file.
228 >
229 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
230 >
231 > 1. -c command line option added to fbsql example program. Used to set connection
232 >   character set.
233 >
234 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
235 >
236 > 1. Firebird 4 support added.
237 >
238 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
239 >   extended precision NUMERIC fields are supported.
240 >
241 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
242 >
243 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
244 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
245 >
246 > 5. IBExtract now supports FB4 enhancements:
247 >   - new data types as above
248 >   - Identity column extensions
249 >   - Default user role
250 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
251 >   - Internal Functions
252 >
253 > 6. IBExtract: new event: OnExtractLines.
254 >
255 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
256 >
257 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
258 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
259 >
260 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
261 >   format for rendering a time zone.
262 >
263 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
264 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
265 >
266 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
267 >    IIBGUIInterface and IIBTimerInf respectively.
268 >
269 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
270 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
271 >
272 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
273 >    truncated to its fixed character width rather than being right padded with
274 >    white space to the maximum data size.
275 >
276 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
277 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
278 >    also empty.
279 >
280 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
281 >
282 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
283 >    connect string. The database name is extracted from the connect string.
284 >
285 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
286 >
287 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
288 >
289 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
290 >    not being present as required.
291 >
292 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
293 >    version that can be customised to work with other database drivers.
294 >
295 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
296 >    unnecessary CR at end of line on Unix platforms.
297 >
298 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
299 >    seconds in order to reduce risk of message loss.
300 >
301 > 23. ISQLMonitor: read and write count statistics now available via:
302 >      property TIBSQLMonitor.ReadCount;
303 >      IIBSQLMonitorHook.GetWriteCount: integer;
304 >
305 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

308  
309   1.  TIBStringField: when a string value is read from a dataset buffer, if the
310      number of UTF8 characters exceeds the string size then string is truncated
# Line 10 | Line 316 | IBX Change Log  version (2.3-5 Build 122
316      SQLFilterParams property is assumed to be a SQL condition clause and
317      ANDed into the Where clause of the SQL Select statement provided as a
318      dataset property. Each such SQL condition thus acts as an additional filter
319 <    on the dataset. (Not yet tested)
319 >    on the dataset.
320  
321   3.  The Filtered property inherited from TDataset is no longer used for SQL (server
322      side filters).
323  
324 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
325 +   text matches complete entry.
326 +
327 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
328 +   dataset are active (avoids risk of access violation if master is inactive)
329 +
330 + 6. TIBEvents: Registered property can now be set at design time even if database not open
331 +
332 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
333 +   This should prevent "spillover" of events between sessions.
334 +
335 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
336 +   This should ensure that the internal buffer is set up correctly and avoids
337 +   a duplicate initial row.
338 +
339 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
340 +   That is, the DataSize should be the field size * character set width. The
341 +   value returned by DataSize is now the same as the Dataset buffer size reserved
342 +   for the field.
343 +
344 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
345 +
346 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
347 +    and vice-versa. This may result in an exception being raised (correctly) for
348 +    older programs when using dataset fields added to a form and the database has been
349 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
350 +    In such cases, the field needs to be deleted in the IDE fields editor and then
351 +    added back in.
352 +
353 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
354 +    false if query contains only white space and not just empty.
355 +
356 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
357 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
358 +    is cancelled.
359 +
360 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
361 +    called on a null field.
362 +
363 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
364 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
365 + set.
366 +
367 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
368 +    a cached update is applied and an exception is raised.
369 +
370 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
371 +
372 + 17. Console Mode Local Database support: backup/restore should now work correctly.
373 +
374 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
375 +    possible and an exception raised.
376 +
377 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
378 +    below this version no. and upgrade not possible.
