1 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
2 +
3 + 1. TIBTransaction: new properties
4 +    property TransactionID: integer read GetTransactionID;
5 +    property IsReadOnly: boolean read GetIsReadOnly;
6 +    {published}
7 +    property TransactionName: string read FTransactionName write SetTransactionName;
8 +
9 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
10 +   Insert or Update...Returning. This allows blobs and arrays to be returned
11 +   by the statement.
12 +
13 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
14 +
15 + 4. TransactionName initialised to a newly generated GUID if empty.
16 +
17 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
18 +   for the fbintf package's journaling capability. TIBJournal is used to set the
19 +   file path and filename for the journal file and to Enabled (start journaling) and
20 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
21 +   more information, and comments in IBJournal.pas.
22 +
23 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
24 +
25 + 7. Bug fix: blob id no longer set to null on update when blob has not been
26 +   retrieved.
27 +
28 + 8. Row auto refreshed on update/insert if blob or array field updated and field
29 +   not in a returning clause.
30 +
31 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
32 +   buffer overhead and avoids problem when refresh query has a different column
33 +   count to select query i.e. incorrectly changing number of columns.
34 +
35 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
36 +
37 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
38 +    string. Note that the Version property returns an InterBase compatible version string.
39 +
40 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
41 +
42 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
43 +
44 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
45 +   This is for compatibility with Firebird 5 where Update...Returning can return
46 +   a cursor.
47 +
48 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
49 +
50 + 1. Add try-..except check when initially loading library in IDE. This should
51 + ensure that IDE continues to load even when a failure occurs in IBX load
52 + library.
53 +
54 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
55 +   hence will correctly detect end of the outer containing block when the block
56 +   contains a SELECT ... CASE ... END construct.
57 +
58 + 3. IBExtract: some further tidying up to remove extraneous white space.
59 +
60 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
61 +   errors when extra elements are added to DB.TFieldType.
62 +
63 + 5. IBUpdate: updated to reflect changes to ISQLParam.
64 +
65 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
66 +
67 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
68 +
69 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
70 +
71 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
72 +
73 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
74 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
75 +
76 + 2. TIBSQL: Batch Update/Insert support added.
77 +
78 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
79 +   is no longer automatically converted to upper case when it is syntactically a
80 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
81 +   as CREATE PROCEDURE "iCASE".
82 +
83 +   There could be a backwards compatibility issue when the StoredProcName was entered
84 +   manually at design time. That is not selected from the drop down list. If the
85 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
86 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
87 +   ensure that the value of the StoredProcName is all upper case, unless it was
88 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
89 +   quotes).
90 +
91 +   Note that when a stored procedure name was declared delimited in double quotes,
92 +   as in the first example above, the value of the StoredProcName property must not
93 +   include the delimiters (double quotes).
94 +
95 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
96 +   upgrade.conf was not found. This replaces silently ignoring the problem.
97 +
98 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
99 +   'Version.%.3d' and is used to generate the section header names (for a given
100 +   version no.) in the upgrade.conf file.
101 +
102 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
103 +
104 + 1. -c command line option added to fbsql example program. Used to set connection
105 +   character set.
106 +
107 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
108 +
109 + 1. Firebird 4 support added.
110 +
111 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
112 +   extended precision NUMERIC fields are supported.
113 +
114 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
115 +
116 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
117 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
118 +
119 + 5. IBExtract now supports FB4 enhancements:
120 +   - new data types as above
121 +   - Identity column extensions
122 +   - Default user role
123 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
124 +   - Internal Functions
125 +
126 + 6. IBExtract: new event: OnExtractLines.
127 +
128 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
129 +
130 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
131 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
132 +
133 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
134 +   format for rendering a time zone.
135 +
136 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
137 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
138 +
139 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
140 +    IIBGUIInterface and IIBTimerInf respectively.
141 +
142 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
143 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
144 +
145 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
146 +    truncated to its fixed character width rather than being right padded with
147 +    white space to the maximum data size.
148 +
149 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
150 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
151 +    also empty.
152 +
153 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
154 +
155 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
156 +    connect string. The database name is extracted from the connect string.
157 +
158 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
159 +
160 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
161 +
162 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
163 +    not being present as required.
164 +
165 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
166 +    version that can be customised to work with other database drivers.
167 +
168 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
169 +    unnecessary CR at end of line on Unix platforms.
170 +
171 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
172 +    seconds in order to reduce risk of message loss.
173 +
174 + 23. ISQLMonitor: read and write count statistics now available via:
175 +      property TIBSQLMonitor.ReadCount;
176 +      IIBSQLMonitorHook.GetWriteCount: integer;
177 +
178 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
179 +
180 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
181 +
182 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
183 +    number of UTF8 characters exceeds the string size then string is truncated
184 +    to the maximum string size. This is  usually a problem with fixed width columns
185 +    right padded with white space.
186 +
187 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
188 +    If SQLFiltered is set then when a dataset is opened, each line in the
189 +    SQLFilterParams property is assumed to be a SQL condition clause and
190 +    ANDed into the Where clause of the SQL Select statement provided as a
191 +    dataset property. Each such SQL condition thus acts as an additional filter
192 +    on the dataset.
193 +
194 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
195 +    side filters).
196 +
197 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
198 +   text matches complete entry.
199 +
200 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
201 +   dataset are active (avoids risk of access violation if master is inactive)
202 +
203 + 6. TIBEvents: Registered property can now be set at design time even if database not open
204 +
205 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
206 +   This should prevent "spillover" of events between sessions.
207 +
208 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
209 +   This should ensure that the internal buffer is set up correctly and avoids
210 +   a duplicate initial row.
211 +
212 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
213 +   That is, the DataSize should be the field size * character set width. The
214 +   value returned by DataSize is now the same as the Dataset buffer size reserved
215 +   for the field.
216 +
217 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
218 +
219 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
220 +    and vice-versa. This may result in an exception being raised (correctly) for
221 +    older programs when using dataset fields added to a form and the database has been
222 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
223 +    In such cases, the field needs to be deleted in the IDE fields editor and then
224 +    added back in.
225 +
226 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
227 +    false if query contains only white space and not just empty.
228 +
229 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
230 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
231 +    is cancelled.
232 +
233 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
234 +    called on a null field.
235 +
236 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
237 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
238 + set.
239 +
240 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
241 +    a cached update is applied and an exception is raised.
242 +
243 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
244 +
245 + 17. Console Mode Local Database support: backup/restore should now work correctly.
246 +
247 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
248 +    possible and an exception raised.
249 +
250 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
251 +    below this version no. and upgrade not possible.
252 +
253 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
254 +
255 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
256 +    not SQL Identifiers are now supported.
257 +
258 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
259 +    passed to the Firebird engine for execution.
260 +
261 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
262 +    is made to scroll back.
263 +
264 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
265 +
266 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
267 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
268 +
269 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
270 +   validated. If no match is found in the list of field names and the database has
271 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
272 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
273 +
274 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
275 +   with fpc 3.2.
276 +
277 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
278 +
279 +
280 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
281 +   and is used to override the default settings in the client side "firebird.conf" This
282 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
283 +   Each line of the string list should be a setting in the same format as "firebird.conf".
284 +   For example "WireCompression = true" in order to request wire compression on the client side.
285 +
286 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
287 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
288 +   also require a compatible setting in the server side "firebird.conf". For example
289 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
290 +   compression to be used.
291 +
292 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
293 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
294 +   ibx/examples/dbinfo for examples of how to display this information.
295 +
296 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
297 +   is a "convenience" property. If set the "WireCompression=true" is added to the
298 +   ConfigOverrides. If unchecked then this setting is removed.
299 +
300 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
301 +   not "INT64".
302 +
303 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
304 +   These are:
305 +    property TimestampFormat: string;
306 +    property DateFormat: string;
307 +    property TimeFormat: string;
308 +
309 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
310 +   DATETIME and TIME. The format strings use the standard FPC date/time format
311 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
312 +
313 +   If any of the above properties are set to an empty string, then the locale default
314 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
315 +   locale default is extended by appending '.zzz' to include milliseconds.
316 +
317 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
318 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
319 +
320 + 5. New published property for TIBCSVDataOut:
321 +     property QuoteStrings: boolean (default true)
322 +
323 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
324 +   used to delimit each and every string in the output.
325 +
326 + 6. New published properties for TIBCSVDataOut:
327 +    property FieldSeparator: string;
328 +    property HeaderSeparator: string;
329 +
330 +   Respectively, these provide the separator character(s) used to separate fields
331 +   in data and header rows. Both default to ','.
332 +
333 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
334 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
335 +    property OnFormatTextString;
336 +
337 +   This event handler can be used to process text strings before they are included
338 +   in the output e.g. to replace unprintable characters with alternative strings.
339 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
340 +
341 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
342 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
343 +   and without raising and exception if it does not.
344 +
345 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
346 +   consistency with SQL queries.
347 +
348 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
349 +    When true, SQL statement parameter names are parsed case sensitive. Note for
350 +    TIBDataSet only applies to Select query.
351 +
352 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
353 +    an IDE exception.
354 +
355 + 12. LocalDBSupport: initial database creation should now work correctly
356 +    when the schema source is an sql file.
357 +
358 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
359 +    when defined, this handler will be called by the internal TIBXScript during
360 +    initial database creation when the schema source is an sql file and may be used
361 +    to provide a visual indication of progress in console mode.
362 +
363 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
364 +    to true while a new local database is being created and its schema populated.
365 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
366 +    when the database is disconnected/connected during the create DB procedure.
367 +
368 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
369 +    are now always ignored and replaced by the user name and password provided as
370 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
371 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
372 +    completely ignored if this property is true.
373 +
374 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
375 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
376 +    ImageIndex and SelectImageIndex values on AddNode.
377 +
378 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
379 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
380 +    the same database connection.
381 +
382 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
383 +    if provided, this should be an conditional SQL expression suitable for
384 +    including in an SQL Select statement "where" clause. If non-empty and the
385 +    "Filtered" property is true then the SQL expression provided as the value of
386 +    the "Filter" property is "ANDed" with any existing condition statement
387 +    in the SQL statement's "Where" clause.
388 +
389 +    If the "Filter" property is set at run time, the "Filtered" property is true
390 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
391 +
392 +    The "Filter" condition may include IBX style parameters. In which case, their
393 +    value must be set by the dataset's "OnBeforeOpen" event handler.
394 +
395 +    This is a public property for TIBDataSet and TIBQuery query and intended for
396 +    use at run time.
397 +
398 +    Note: The property is a published property of TIBTable. The TIBTable functionality
399 +    is unaffected by this change.
400 +
401 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
402 +
403 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
404 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
405 +   mode apps.
406 +
407 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
408 +   statement. This avoids problems if "Execute Block" is used as the Query.
409 +
410 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
411 +   internal SQL tokeniser routines.
412 +
413 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
414 +   as a select statement, with or without CTEs.
415 +
416 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
417 +
418 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
419 +   internal SQL tokeniser routines.
420 +
421 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
422 +    being raised for valid set statements processed by a data formatter.
423 +
424 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
425 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
426 +   the path of the Firebird Library used by the database/services connection.
427 +
428 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
429 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
430 +   services connection.
431 +
432 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected

435 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
436 +    view of whether the text box should be editable when no DataSource is specified.
437 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
438 +    ReadOnly is false, the text box is editable when no DataSource is specified.
439 +
440 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
441 +    the FBLIB environment variable. If you do not want to permit this then you
442 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
443 +    this setting.
