1 + IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +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 + 2. IBUpdateSQL. update internal queries if parent dataset database changed.
7 +
8 + 3. IBUpdateSQL: Do not prepare an empty internal query.
9 +
10 + 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
11 +
12 + 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
13 +
14 + IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
15 +
16 + 1. Maintenance update of 2.6.0. This version is still at beta.
17 +
18 + 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
19 +   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
20 +
21 + 3. ibxscript: When parsing a store procedure or function with a variable name
22 +   enclosed in doublequotes, the double quotes are no longer removed.
23 +
24 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
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
# Line 10 | Line 272 | IBX Change Log  version (2.3-5 Build 123
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. (Not yet tested)
275 >    on the dataset.
276  
277   3.  The Filtered property inherited from TDataset is no longer used for SQL (server
278      side filters).
# Line 45 | Line 307 | IBX Change Log  version (2.3-5 Build 123
307      added back in.
308  
309   12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
310 <    false if query contains white space and not just empty.
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 +
