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.

29 >
30 > 1. Update to calls to EInterbaseError to add default code page. Consequential
31 >   on change to fbintf.
32 >
33 > 2. Update some examples to replace test for null date with the NullDate constant
34 >   instead of zero. This is because Laz 3.0 changes the value of NullDate.

37 >
38 > 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
39 >   with later versions of fpc - later than 3.2.2.
40 >
41 > 2. IBUpdateSQL. update internal queries if parent dataset database changed.
42 >
43 > 3. IBUpdateSQL: Do not prepare an empty internal query.
44 >
45 > 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
46 >
47 > 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count

50 >
51 > 1. Maintenance update of 2.6.0. This version is still at beta.
52 >
53 > 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.

56 > 3. ibxscript: When parsing a store procedure or function with a variable name
57 >   enclosed in doublequotes, the double quotes are no longer removed.

59 > IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
60 >
61 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
62 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
63 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
64 >      ISSUES TO support@mwasoftware.co.uk
65 >
66 > 1. Complete rewrite of internal buffer management in order to improve performance
67 >   and maintainability. Highlights:
68 >
69 >   * Extending the size of the buffer pool no longer has to copy the entire record
70 >     cache. Instead, a new extent is simply added to the buffer pool.
71 >   * A memory to memory copy of each display buffer now is avoided when scolling the
72 >     dataset.
73 >   * A separate set of buffers is now used for calculated fields. This avoids
74 >     having to keep copies of calculated field values in the buffer cache.
75 >   * Compact bitmaps are used to record null status and need to refresh in each
76 >     buffer.
77 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
78 >     buffer type in FCL-DB.
79 >
80 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
81 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
82 >
83 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
84 >   If either or both of these flags are set at design time (using the fields editor)
85 >   then this forces a row refresh on respectively insert or update, or both, when the
86 >   corresponding field is not present in an SQL RETURNING clause.
87 >
88 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
89 >   maintainability and readability and to add identification of primary key fields.
90 >
91 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
92 >   as a refresh of the current row. However, this is different behaviour to that described
93 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
94 >   the dataset from the underlying database, and attempts to reposition the cursor on
95 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
96 >
97 > 6. A progammatic Row Refresh should no longer be required.
98 >   Use Insert/Update... returning to refresh any fields that may change following an
99 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
100 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
101 >   for the field at Design Time to force a row refresh if not in the returning clause.
102 >
103 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
104 >
105 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
106 >   This gives the number of buffers in the initial block for the buffer pool in
107 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
108 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
109 >   for small datasets.

112 >
113 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
114 >
115 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
116 >
117 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
118 >
119 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
120 >
121 > 1. TIBTransaction: new properties
122 >    property TransactionID: integer read GetTransactionID;
123 >    property IsReadOnly: boolean read GetIsReadOnly;
124 >    {published}
125 >    property TransactionName: string read FTransactionName write SetTransactionName;
126 >
127 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
128 >   Insert or Update...Returning. This allows blobs and arrays to be returned
129 >   by the statement.
130 >
131 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
132 >
133 > 4. TransactionName initialised to a newly generated GUID if empty.
134 >
135 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
136 >   for the fbintf package's journaling capability. TIBJournal is used to set the
137 >   file path and filename for the journal file and to Enabled (start journaling) and
138 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
139 >   more information, and comments in IBJournal.pas.
140 >
141 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
142 >
143 > 7. Bug fix: blob id no longer set to null on update when blob has not been
144 >   retrieved.
145 >
146 > 8. Row auto refreshed on update/insert if blob or array field updated and field
147 >   not in a returning clause.
148 >
149 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
150 >   buffer overhead and avoids problem when refresh query has a different column
151 >   count to select query i.e. incorrectly changing number of columns.
152 >
153 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
154 >
155 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
156 >    string. Note that the Version property returns an InterBase compatible version string.
157 >
158 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
159 >
160 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
161 >
162 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
163 >   This is for compatibility with Firebird 5 where Update...Returning can return
164 >   a cursor.
165 >
166 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
167 >
168 > 1. Add try-..except check when initially loading library in IDE. This should
169 > ensure that IDE continues to load even when a failure occurs in IBX load
170 > library.
171 >
172 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
173 >   hence will correctly detect end of the outer containing block when the block
174 >   contains a SELECT ... CASE ... END construct.
175 >
176 > 3. IBExtract: some further tidying up to remove extraneous white space.
177 >
178 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
179 >   errors when extra elements are added to DB.TFieldType.
180 >
181 > 5. IBUpdate: updated to reflect changes to ISQLParam.
182 >
183 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
184 >
185 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
186 >
187 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
188 >
189 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
190 >
191 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
192 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
193 >
194 > 2. TIBSQL: Batch Update/Insert support added.
195 >
196 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
197 >   is no longer automatically converted to upper case when it is syntactically a
198 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
199 >   as CREATE PROCEDURE "iCASE".
200 >
201 >   There could be a backwards compatibility issue when the StoredProcName was entered
202 >   manually at design time. That is not selected from the drop down list. If the
203 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
204 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
205 >   ensure that the value of the StoredProcName is all upper case, unless it was
206 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
207 >   quotes).
208 >
209 >   Note that when a stored procedure name was declared delimited in double quotes,
210 >   as in the first example above, the value of the StoredProcName property must not
211 >   include the delimiters (double quotes).
212 >
213 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
214 >   upgrade.conf was not found. This replaces silently ignoring the problem.
215 >
216 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
217 >   'Version.%.3d' and is used to generate the section header names (for a given
218 >   version no.) in the upgrade.conf file.
219 >
220 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
221 >
222 > 1. -c command line option added to fbsql example program. Used to set connection
223 >   character set.
224 >
225 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
226 >
227 > 1. Firebird 4 support added.
228 >
229 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
230 >   extended precision NUMERIC fields are supported.
231 >
232 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
233 >
234 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
235 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
236 >
237 > 5. IBExtract now supports FB4 enhancements:
238 >   - new data types as above
239 >   - Identity column extensions
240 >   - Default user role
241 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
242 >   - Internal Functions
243 >
244 > 6. IBExtract: new event: OnExtractLines.
245 >
246 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
247 >
248 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
249 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
250 >
251 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
252 >   format for rendering a time zone.
253 >
254 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
255 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
256 >
257 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
258 >    IIBGUIInterface and IIBTimerInf respectively.
259 >
260 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
261 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
262 >
263 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
264 >    truncated to its fixed character width rather than being right padded with
265 >    white space to the maximum data size.
266 >
267 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
268 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
269 >    also empty.
270 >
271 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
272 >
273 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
274 >    connect string. The database name is extracted from the connect string.
275 >
276 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
277 >
278 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
279 >
280 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
281 >    not being present as required.
282 >
283 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
284 >    version that can be customised to work with other database drivers.
285 >
286 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
287 >    unnecessary CR at end of line on Unix platforms.
288 >
289 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
290 >    seconds in order to reduce risk of message loss.
291 >
292 > 23. ISQLMonitor: read and write count statistics now available via:
293 >      property TIBSQLMonitor.ReadCount;
294 >      IIBSQLMonitorHook.GetWriteCount: integer;
295 >
296 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

300   1.  TIBStringField: when a string value is read from a dataset buffer, if the
301      number of UTF8 characters exceeds the string size then string is truncated
# Line 10 | Line 307 | IBX Change Log  version (2.3-5 Build 122
307      SQLFilterParams property is assumed to be a SQL condition clause and
308      ANDed into the Where clause of the SQL Select statement provided as a
309      dataset property. Each such SQL condition thus acts as an additional filter
310 <    on the dataset. (Not yet tested)
310 >    on the dataset.
311  
312   3.  The Filtered property inherited from TDataset is no longer used for SQL (server
313      side filters).
314  
315 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
316 +   text matches complete entry.
317 +
318 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
319 +   dataset are active (avoids risk of access violation if master is inactive)
320 +
321 + 6. TIBEvents: Registered property can now be set at design time even if database not open
322 +
323 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
324 +   This should prevent "spillover" of events between sessions.
325 +
326 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
327 +   This should ensure that the internal buffer is set up correctly and avoids
328 +   a duplicate initial row.
329 +
330 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
331 +   That is, the DataSize should be the field size * character set width. The
332 +   value returned by DataSize is now the same as the Dataset buffer size reserved
333 +   for the field.
334 +
335 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
336 +
337 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
338 +    and vice-versa. This may result in an exception being raised (correctly) for
339 +    older programs when using dataset fields added to a form and the database has been
340 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
341 +    In such cases, the field needs to be deleted in the IDE fields editor and then
342 +    added back in.
343 +
344 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
345 +    false if query contains only white space and not just empty.
346 +
347 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
348 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
349 +    is cancelled.
350 +
351 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
352 +    called on a null field.
353 +
354 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
355 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
356 + set.
357 +
358 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
359 +    a cached update is applied and an exception is raised.
360 +
361 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
362 +
363 + 17. Console Mode Local Database support: backup/restore should now work correctly.
364 +
365 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
366 +    possible and an exception raised.
367 +
368 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
369 +    below this version no. and upgrade not possible.
