44 >
45 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
46 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
47 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
48 >      ISSUES TO support@mwasoftware.co.uk
49 >
50 > 1. Complete rewrite of internal buffer management in order to improve performance
51 >   and maintainability. Highlights:
52 >
53 >   * Extending the size of the buffer pool no longer has to copy the entire record
54 >     cache. Instead, a new extent is simply added to the buffer pool.
55 >   * A memory to memory copy of each display buffer now is avoided when scolling the
56 >     dataset.
57 >   * A separate set of buffers is now used for calculated fields. This avoids
58 >     having to keep copies of calculated field values in the buffer cache.
59 >   * Compact bitmaps are used to record null status and need to refresh in each
60 >     buffer.
61 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
62 >     buffer type in FCL-DB.
63 >
64 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
65 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
66 >
67 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
68 >   If either or both of these flags are set at design time (using the fields editor)
69 >   then this forces a row refresh on respectively insert or update, or both, when the
70 >   corresponding field is not present in an SQL RETURNING clause.
71 >
72 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
73 >   maintainability and readability and to add identification of primary key fields.
74 >
75 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
76 >   as a refresh of the current row. However, this is different behaviour to that described
77 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
78 >   the dataset from the underlying database, and attempts to reposition the cursor on
79 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
80 >
81 > 6. A progammatic Row Refresh should no longer be required.
82 >   Use Insert/Update... returning to refresh any fields that may change following an
83 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
84 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
85 >   for the field at Design Time to force a row refresh if not in the returning clause.
86 >
87 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
88 >
89 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
90 >   This gives the number of buffers in the initial block for the buffer pool in
91 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
92 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
93 >   for small datasets.

95 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
96 >
97 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
98 >
99 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
100 >
101 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
102 >
103 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
104 >
105 > 1. TIBTransaction: new properties
106 >    property TransactionID: integer read GetTransactionID;
107 >    property IsReadOnly: boolean read GetIsReadOnly;
108 >    {published}
109 >    property TransactionName: string read FTransactionName write SetTransactionName;
110 >
111 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
112 >   Insert or Update...Returning. This allows blobs and arrays to be returned
113 >   by the statement.
114 >
115 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
116 >
117 > 4. TransactionName initialised to a newly generated GUID if empty.
118 >
119 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
120 >   for the fbintf package's journaling capability. TIBJournal is used to set the
121 >   file path and filename for the journal file and to Enabled (start journaling) and
122 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
123 >   more information, and comments in IBJournal.pas.
124 >
125 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
126 >
127 > 7. Bug fix: blob id no longer set to null on update when blob has not been
128 >   retrieved.
129 >
130 > 8. Row auto refreshed on update/insert if blob or array field updated and field
131 >   not in a returning clause.
132 >
133 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
134 >   buffer overhead and avoids problem when refresh query has a different column
135 >   count to select query i.e. incorrectly changing number of columns.
136 >
137 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
138 >
139 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
140 >    string. Note that the Version property returns an InterBase compatible version string.
141 >
142 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
143 >
144 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
145 >
146 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
147 >   This is for compatibility with Firebird 5 where Update...Returning can return
148 >   a cursor.
149 >
150 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
151 >
152 > 1. Add try-..except check when initially loading library in IDE. This should
153 > ensure that IDE continues to load even when a failure occurs in IBX load
154 > library.
155 >
156 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
157 >   hence will correctly detect end of the outer containing block when the block
158 >   contains a SELECT ... CASE ... END construct.
159 >
160 > 3. IBExtract: some further tidying up to remove extraneous white space.
161 >
162 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
163 >   errors when extra elements are added to DB.TFieldType.
164 >
165 > 5. IBUpdate: updated to reflect changes to ISQLParam.
166 >
167 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
168 >
169 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
170 >
171 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
172 >
173 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
174 >
175 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
176 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
177 >
178 > 2. TIBSQL: Batch Update/Insert support added.
179 >
180 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
181 >   is no longer automatically converted to upper case when it is syntactically a
182 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
183 >   as CREATE PROCEDURE "iCASE".
184 >
185 >   There could be a backwards compatibility issue when the StoredProcName was entered
186 >   manually at design time. That is not selected from the drop down list. If the
187 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
188 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
189 >   ensure that the value of the StoredProcName is all upper case, unless it was
190 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
191 >   quotes).
192 >
193 >   Note that when a stored procedure name was declared delimited in double quotes,
194 >   as in the first example above, the value of the StoredProcName property must not
195 >   include the delimiters (double quotes).
196 >
197 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
198 >   upgrade.conf was not found. This replaces silently ignoring the problem.
199 >
200 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
201 >   'Version.%.3d' and is used to generate the section header names (for a given
202 >   version no.) in the upgrade.conf file.
203 >
204 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
205 >
206 > 1. -c command line option added to fbsql example program. Used to set connection
207 >   character set.

209 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
210 >
211 > 1. Firebird 4 support added.
212 >
213 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
214 >   extended precision NUMERIC fields are supported.
215 >
216 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
217 >
218 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
219 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
220 >
221 > 5. IBExtract now supports FB4 enhancements:
222 >   - new data types as above
223 >   - Identity column extensions
224 >   - Default user role
225 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
226 >   - Internal Functions
227 >
228 > 6. IBExtract: new event: OnExtractLines.
229 >
230 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
231 >
232 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
233 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
234 >
235 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
236 >   format for rendering a time zone.
237 >
238 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
239 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
240 >
241 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
242 >    IIBGUIInterface and IIBTimerInf respectively.
243 >
244 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
245 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
246 >
247 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
248 >    truncated to its fixed character width rather than being right padded with
249 >    white space to the maximum data size.
250 >
251 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
252 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
253 >    also empty.
254 >
255 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
256 >
257 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
258 >    connect string. The database name is extracted from the connect string.
259 >
260 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
261 >
262 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
263 >
264 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
265 >    not being present as required.
266 >
267 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
268 >    version that can be customised to work with other database drivers.
269 >
270 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
271 >    unnecessary CR at end of line on Unix platforms.
272 >
273 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
274 >    seconds in order to reduce risk of message loss.
275 >
276 > 23. ISQLMonitor: read and write count statistics now available via:
277 >      property TIBSQLMonitor.ReadCount;
278 >      IIBSQLMonitorHook.GetWriteCount: integer;
279 >
280 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

283  
284   1.  TIBStringField: when a string value is read from a dataset buffer, if the
285      number of UTF8 characters exceeds the string size then string is truncated
# Line 10 | Line 291 | IBX Change Log  version (2.3-5 Build 122
291      SQLFilterParams property is assumed to be a SQL condition clause and
292      ANDed into the Where clause of the SQL Select statement provided as a
293      dataset property. Each such SQL condition thus acts as an additional filter
294 <    on the dataset. (Not yet tested)
294 >    on the dataset.
295  
296   3.  The Filtered property inherited from TDataset is no longer used for SQL (server
297      side filters).
298  
299 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
300 +   text matches complete entry.
301 +
302 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
303 +   dataset are active (avoids risk of access violation if master is inactive)
304 +
305 + 6. TIBEvents: Registered property can now be set at design time even if database not open
306 +
307 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
308 +   This should prevent "spillover" of events between sessions.
309 +
310 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
311 +   This should ensure that the internal buffer is set up correctly and avoids
312 +   a duplicate initial row.
313 +
314 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
315 +   That is, the DataSize should be the field size * character set width. The
316 +   value returned by DataSize is now the same as the Dataset buffer size reserved
317 +   for the field.
318 +
319 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
320 +
321 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
322 +    and vice-versa. This may result in an exception being raised (correctly) for
323 +    older programs when using dataset fields added to a form and the database has been
324 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
325 +    In such cases, the field needs to be deleted in the IDE fields editor and then
326 +    added back in.
327 +
328 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
329 +    false if query contains only white space and not just empty.
330 +
331 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
332 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
333 +    is cancelled.
334 +
335 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
336 +    called on a null field.
337 +
338 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
339 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
340 + set.
341 +
342 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
343 +    a cached update is applied and an exception is raised.
344 +
345 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
346 +
347 + 17. Console Mode Local Database support: backup/restore should now work correctly.
348 +
349 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
350 +    possible and an exception raised.
351 +
352 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
353 +    below this version no. and upgrade not possible.
