25 >
26 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
27 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
28 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
29 >      ISSUES TO support@mwasoftware.co.uk
30 >
31 > 1. Complete rewrite of internal buffer management in order to improve performance
32 >   and maintainability. Highlights:
33 >
34 >   * Extending the size of the buffer pool no longer has to copy the entire record
35 >     cache. Instead, a new extent is simply added to the buffer pool.
36 >   * A memory to memory copy of each display buffer now is avoided when scolling the
37 >     dataset.
38 >   * A separate set of buffers is now used for calculated fields. This avoids
39 >     having to keep copies of calculated field values in the buffer cache.
40 >   * Compact bitmaps are used to record null status and need to refresh in each
41 >     buffer.
42 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
43 >     buffer type in FCL-DB.
44 >
45 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
46 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
47 >
48 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
49 >   If either or both of these flags are set at design time (using the fields editor)
50 >   then this forces a row refresh on respectively insert or update, or both, when the
51 >   corresponding field is not present in an SQL RETURNING clause.
52 >
53 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
54 >   maintainability and readability and to add identification of primary key fields.
55 >
56 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
57 >   as a refresh of the current row. However, this is different behaviour to that described
58 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
59 >   the dataset from the underlying database, and attempts to reposition the cursor on
60 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
61 >
62 > 6. A progammatic Row Refresh should no longer be required.
63 >   Use Insert/Update... returning to refresh any fields that may change following an
64 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
65 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
66 >   for the field at Design Time to force a row refresh if not in the returning clause.
67 >
68 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
69 >
70 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
71 >   This gives the number of buffers in the initial block for the buffer pool in
72 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
73 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
74 >   for small datasets.
75 >
76 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
77 >
78 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
79 >
80 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
81 >
82 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
83 >
84 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
85 >
86 > 1. TIBTransaction: new properties
87 >    property TransactionID: integer read GetTransactionID;
88 >    property IsReadOnly: boolean read GetIsReadOnly;
89 >    {published}
90 >    property TransactionName: string read FTransactionName write SetTransactionName;
91 >
92 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
93 >   Insert or Update...Returning. This allows blobs and arrays to be returned
94 >   by the statement.
95 >
96 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
97 >
98 > 4. TransactionName initialised to a newly generated GUID if empty.
99 >
100 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
101 >   for the fbintf package's journaling capability. TIBJournal is used to set the
102 >   file path and filename for the journal file and to Enabled (start journaling) and
103 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
104 >   more information, and comments in IBJournal.pas.
105 >
106 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
107 >
108 > 7. Bug fix: blob id no longer set to null on update when blob has not been
109 >   retrieved.
110 >
111 > 8. Row auto refreshed on update/insert if blob or array field updated and field
112 >   not in a returning clause.
113 >
114 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
115 >   buffer overhead and avoids problem when refresh query has a different column
116 >   count to select query i.e. incorrectly changing number of columns.
117 >
118 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
119 >
120 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
121 >    string. Note that the Version property returns an InterBase compatible version string.
122 >
123 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
124 >
125 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
126 >
127 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
128 >   This is for compatibility with Firebird 5 where Update...Returning can return
129 >   a cursor.
130 >
131 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
132 >
133 > 1. Add try-..except check when initially loading library in IDE. This should
134 > ensure that IDE continues to load even when a failure occurs in IBX load
135 > library.
136 >
137 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
138 >   hence will correctly detect end of the outer containing block when the block
139 >   contains a SELECT ... CASE ... END construct.
140 >
141 > 3. IBExtract: some further tidying up to remove extraneous white space.
142 >
143 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
144 >   errors when extra elements are added to DB.TFieldType.
145 >
146 > 5. IBUpdate: updated to reflect changes to ISQLParam.
147 >
148 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
149 >
150 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
151 >
152 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
153 >
154 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
155 >
156 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
157 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
158 >
159 > 2. TIBSQL: Batch Update/Insert support added.
160 >
161 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
162 >   is no longer automatically converted to upper case when it is syntactically a
163 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
164 >   as CREATE PROCEDURE "iCASE".
165 >
166 >   There could be a backwards compatibility issue when the StoredProcName was entered
167 >   manually at design time. That is not selected from the drop down list. If the
168 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
169 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
170 >   ensure that the value of the StoredProcName is all upper case, unless it was
171 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
172 >   quotes).
173 >
174 >   Note that when a stored procedure name was declared delimited in double quotes,
175 >   as in the first example above, the value of the StoredProcName property must not
176 >   include the delimiters (double quotes).
177 >
178 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
179 >   upgrade.conf was not found. This replaces silently ignoring the problem.
180 >
181 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
182 >   'Version.%.3d' and is used to generate the section header names (for a given
183 >   version no.) in the upgrade.conf file.
184 >
185 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
186 >
187 > 1. -c command line option added to fbsql example program. Used to set connection
188 >   character set.
189 >
190 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
191 >
192 > 1. Firebird 4 support added.
193 >
194 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
195 >   extended precision NUMERIC fields are supported.
196 >
197 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
198 >
199 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
200 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
201 >
202 > 5. IBExtract now supports FB4 enhancements:
203 >   - new data types as above
204 >   - Identity column extensions
205 >   - Default user role
206 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
207 >   - Internal Functions
208 >
209 > 6. IBExtract: new event: OnExtractLines.
210 >
211 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
212 >
213 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
214 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
215 >
216 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
217 >   format for rendering a time zone.
218 >
219 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
220 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
221 >
222 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
223 >    IIBGUIInterface and IIBTimerInf respectively.
224 >
225 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
226 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
227 >
228 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
229 >    truncated to its fixed character width rather than being right padded with
230 >    white space to the maximum data size.
231 >
232 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
233 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
234 >    also empty.
235 >
236 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
237 >
238 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
239 >    connect string. The database name is extracted from the connect string.
240 >
241 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
242 >
243 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
244 >
245 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
246 >    not being present as required.
247 >
248 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
249 >    version that can be customised to work with other database drivers.
250 >
251 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
252 >    unnecessary CR at end of line on Unix platforms.
253 >
254 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
255 >    seconds in order to reduce risk of message loss.
256 >
257 > 23. ISQLMonitor: read and write count statistics now available via:
258 >      property TIBSQLMonitor.ReadCount;
259 >      IIBSQLMonitorHook.GetWriteCount: integer;
260 >
261 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
262 >
263 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
264 >
265 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
266 >    number of UTF8 characters exceeds the string size then string is truncated
267 >    to the maximum string size. This is  usually a problem with fixed width columns
268 >    right padded with white space.
269 >
270 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
271 >    If SQLFiltered is set then when a dataset is opened, each line in the
272 >    SQLFilterParams property is assumed to be a SQL condition clause and
273 >    ANDed into the Where clause of the SQL Select statement provided as a
274 >    dataset property. Each such SQL condition thus acts as an additional filter
275 >    on the dataset.
276 >
277 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
278 >    side filters).
279 >
280 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
281 >   text matches complete entry.
282 >
283 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
284 >   dataset are active (avoids risk of access violation if master is inactive)
285 >
286 > 6. TIBEvents: Registered property can now be set at design time even if database not open
287 >
288 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
289 >   This should prevent "spillover" of events between sessions.
290 >
291 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
292 >   This should ensure that the internal buffer is set up correctly and avoids
293 >   a duplicate initial row.
294 >
295 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
296 >   That is, the DataSize should be the field size * character set width. The
297 >   value returned by DataSize is now the same as the Dataset buffer size reserved
298 >   for the field.
299 >
300 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
301 >
302 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
303 >    and vice-versa. This may result in an exception being raised (correctly) for
304 >    older programs when using dataset fields added to a form and the database has been
305 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
306 >    In such cases, the field needs to be deleted in the IDE fields editor and then
307 >    added back in.
308 >
309 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
310 >    false if query contains only white space and not just empty.
311 >
312 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
313 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
314 >    is cancelled.
315 >
316 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
317 >    called on a null field.
318 >
319 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
320 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
321 > set.
322 >
323 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
324 >    a cached update is applied and an exception is raised.
325 >
326 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
327 >
328 > 17. Console Mode Local Database support: backup/restore should now work correctly.
329 >
330 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
331 >    possible and an exception raised.
332 >
333 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
334 >    below this version no. and upgrade not possible.
335 >

337  
338   1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
339      not SQL Identifiers are now supported.
# Line 6 | Line 341 | IBX Change Log  version (2.3-4 Build 116
341   2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
342      passed to the Firebird engine for execution.
343  
344 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
345 +    is made to scroll back.
346 +
347 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
348 +
349 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
350 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
351 +
352 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
353 +   validated. If no match is found in the list of field names and the database has
354 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
355 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
356 +
357 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
358 +   with fpc 3.2.
