1 + IBX Change Log  version (2.6-2 Build 13992) Mon, 24 Jul 2023 09:26:32 +0100
2 +
3 + 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
4 +   with later versions of fpc - later than 3.2.2.
5 +
6 + IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
7 +
8 + 1. Maintenance update of 2.6.0. This version is still at beta.
9 +
10 + 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
11 +   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
12 +
13 + 3. ibxscript: When parsing a store procedure or function with a variable name
14 +   enclosed in doublequotes, the double quotes are no longer removed.
15 +
16 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
17 +
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.
181 +
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.
254 +
255 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
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
259 +    to the maximum string size. This is  usually a problem with fixed width columns
260 +    right padded with white space.
261 +
262 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
263 +    If SQLFiltered is set then when a dataset is opened, each line in the
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.
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.
