18 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
19 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
20 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
21 >      ISSUES TO support@mwasoftware.co.uk
22 >
23 > 1. Complete rewrite of internal buffer management in order to improve performance
24 >   and maintainability. Highlights:
25 >
26 >   * Extending the size of the buffer pool no longer has to copy the entire record
27 >     cache. Instead, a new extent is simply added to the buffer pool.
28 >   * A memory to memory copy of each display buffer now is avoided when scolling the
29 >     dataset.
30 >   * A separate set of buffers is now used for calculated fields. This avoids
31 >     having to keep copies of calculated field values in the buffer cache.
32 >   * Compact bitmaps are used to record null status and need to refresh in each
33 >     buffer.
34 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
35 >     buffer type in FCL-DB.
36 >
37 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
38 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
39 >
40 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
41 >   If either or both of these flags are set at design time (using the fields editor)
42 >   then this forces a row refresh on respectively insert or update, or both, when the
43 >   corresponding field is not present in an SQL RETURNING clause.
44 >
45 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
46 >   maintainability and readability and to add identification of primary key fields.
47 >
48 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
49 >   as a refresh of the current row. However, this is different behaviour to that described
50 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
51 >   the dataset from the underlying database, and attempts to reposition the cursor on
52 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
53 >
54 > 6. A progammatic Row Refresh should no longer be required.
55 >   Use Insert/Update... returning to refresh any fields that may change following an
56 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
57 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
58 >   for the field at Design Time to force a row refresh if not in the returning clause.
59 >
60 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
61 >
62 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
63 >   This gives the number of buffers in the initial block for the buffer pool in
64 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
65 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
66 >   for small datasets.
67 >
68 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
69 >
70 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
71 >
72 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
73 >
74 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
75 >
76 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
77 >
78 > 1. TIBTransaction: new properties
79 >    property TransactionID: integer read GetTransactionID;
80 >    property IsReadOnly: boolean read GetIsReadOnly;
81 >    {published}
82 >    property TransactionName: string read FTransactionName write SetTransactionName;
83 >
84 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
85 >   Insert or Update...Returning. This allows blobs and arrays to be returned
86 >   by the statement.
87 >
88 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
89 >
90 > 4. TransactionName initialised to a newly generated GUID if empty.
91 >
92 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
93 >   for the fbintf package's journaling capability. TIBJournal is used to set the
94 >   file path and filename for the journal file and to Enabled (start journaling) and
95 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
96 >   more information, and comments in IBJournal.pas.
97 >
98 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
99 >
100 > 7. Bug fix: blob id no longer set to null on update when blob has not been
101 >   retrieved.
102 >
103 > 8. Row auto refreshed on update/insert if blob or array field updated and field
104 >   not in a returning clause.
105 >
106 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
107 >   buffer overhead and avoids problem when refresh query has a different column
108 >   count to select query i.e. incorrectly changing number of columns.
109 >
110 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
111 >
112 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
113 >    string. Note that the Version property returns an InterBase compatible version string.
114 >
115 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
116 >
117 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
118 >
119 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
120 >   This is for compatibility with Firebird 5 where Update...Returning can return
121 >   a cursor.
122 >
123 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
124 >
125 > 1. Add try-..except check when initially loading library in IDE. This should
126 > ensure that IDE continues to load even when a failure occurs in IBX load
127 > library.
128 >
129 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
130 >   hence will correctly detect end of the outer containing block when the block
131 >   contains a SELECT ... CASE ... END construct.
132 >
133 > 3. IBExtract: some further tidying up to remove extraneous white space.
134 >
135 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
136 >   errors when extra elements are added to DB.TFieldType.
137 >
138 > 5. IBUpdate: updated to reflect changes to ISQLParam.
139 >
140 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
141 >
142 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
143 >
144 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
145 >
146 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
147 >
148 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
149 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
150 >
151 > 2. TIBSQL: Batch Update/Insert support added.
152 >
153 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
154 >   is no longer automatically converted to upper case when it is syntactically a
155 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
156 >   as CREATE PROCEDURE "iCASE".
157 >
158 >   There could be a backwards compatibility issue when the StoredProcName was entered
159 >   manually at design time. That is not selected from the drop down list. If the
160 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
161 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
162 >   ensure that the value of the StoredProcName is all upper case, unless it was
163 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
164 >   quotes).
165 >
166 >   Note that when a stored procedure name was declared delimited in double quotes,
167 >   as in the first example above, the value of the StoredProcName property must not
168 >   include the delimiters (double quotes).
169 >
170 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
171 >   upgrade.conf was not found. This replaces silently ignoring the problem.
172 >
173 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
174 >   'Version.%.3d' and is used to generate the section header names (for a given
175 >   version no.) in the upgrade.conf file.
176 >
177 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
178 >
179 > 1. -c command line option added to fbsql example program. Used to set connection
180 >   character set.

182 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
183 >
184 > 1. Firebird 4 support added.
185 >
186 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
187 >   extended precision NUMERIC fields are supported.
188 >
189 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
190 >
191 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
192 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
193 >
194 > 5. IBExtract now supports FB4 enhancements:
195 >   - new data types as above
196 >   - Identity column extensions
197 >   - Default user role
198 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
199 >   - Internal Functions
200 >
201 > 6. IBExtract: new event: OnExtractLines.
202 >
203 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
204 >
205 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
206 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
207 >
208 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
209 >   format for rendering a time zone.
210 >
211 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
212 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
213 >
214 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
215 >    IIBGUIInterface and IIBTimerInf respectively.
216 >
217 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
218 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
219 >
220 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
221 >    truncated to its fixed character width rather than being right padded with
222 >    white space to the maximum data size.
223 >
224 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
225 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
226 >    also empty.
227 >
228 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
229 >
230 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
231 >    connect string. The database name is extracted from the connect string.
232 >
233 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
234 >
235 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
236 >
237 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
238 >    not being present as required.
239 >
240 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
241 >    version that can be customised to work with other database drivers.
242 >
243 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
244 >    unnecessary CR at end of line on Unix platforms.
245 >
246 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
247 >    seconds in order to reduce risk of message loss.
248 >
249 > 23. ISQLMonitor: read and write count statistics now available via:
250 >      property TIBSQLMonitor.ReadCount;
251 >      IIBSQLMonitorHook.GetWriteCount: integer;
252 >
253 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

256  
257   1.  TIBStringField: when a string value is read from a dataset buffer, if the
258      number of UTF8 characters exceeds the string size then string is truncated
# Line 10 | Line 264 | IBX Change Log  version (2.3-5 Build 122
264      SQLFilterParams property is assumed to be a SQL condition clause and
265      ANDed into the Where clause of the SQL Select statement provided as a
266      dataset property. Each such SQL condition thus acts as an additional filter
267 <    on the dataset. (Not yet tested)
267 >    on the dataset.
268  
269   3.  The Filtered property inherited from TDataset is no longer used for SQL (server
270      side filters).
271  
272 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
273 +   text matches complete entry.
274 +
275 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
276 +   dataset are active (avoids risk of access violation if master is inactive)
277 +
278 + 6. TIBEvents: Registered property can now be set at design time even if database not open
279 +
280 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
281 +   This should prevent "spillover" of events between sessions.
282 +
283 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
284 +   This should ensure that the internal buffer is set up correctly and avoids
285 +   a duplicate initial row.
286 +
287 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
288 +   That is, the DataSize should be the field size * character set width. The
289 +   value returned by DataSize is now the same as the Dataset buffer size reserved
290 +   for the field.
291 +
292 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
293 +
294 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
295 +    and vice-versa. This may result in an exception being raised (correctly) for
296 +    older programs when using dataset fields added to a form and the database has been
297 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
298 +    In such cases, the field needs to be deleted in the IDE fields editor and then
299 +    added back in.
300 +
301 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
302 +    false if query contains only white space and not just empty.
303 +
304 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
305 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
306 +    is cancelled.
307 +
308 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
309 +    called on a null field.
310 +
311 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
312 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
313 + set.
314 +
315 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
316 +    a cached update is applied and an exception is raised.
317 +
318 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
319 +
320 + 17. Console Mode Local Database support: backup/restore should now work correctly.
321 +
322 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
323 +    possible and an exception raised.
324 +
325 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
326 +    below this version no. and upgrade not possible.
