1 + IBX Change Log  version (2.5-1 Build nnn) Tue, 6 Dec 2022 23:13:00 +0000
2 +
3 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
4 +
5 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
6 +
7 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
8 +
9 + 1. TIBTransaction: new properties
10 +    property TransactionID: integer read GetTransactionID;
11 +    property IsReadOnly: boolean read GetIsReadOnly;
12 +    {published}
13 +    property TransactionName: string read FTransactionName write SetTransactionName;
14 +
15 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
16 +   Insert or Update...Returning. This allows blobs and arrays to be returned
17 +   by the statement.
18 +
19 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
20 +
21 + 4. TransactionName initialised to a newly generated GUID if empty.
22 +
23 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
24 +   for the fbintf package's journaling capability. TIBJournal is used to set the
25 +   file path and filename for the journal file and to Enabled (start journaling) and
26 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
27 +   more information, and comments in IBJournal.pas.
28 +
29 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
30 +
31 + 7. Bug fix: blob id no longer set to null on update when blob has not been
32 +   retrieved.
33 +
34 + 8. Row auto refreshed on update/insert if blob or array field updated and field
35 +   not in a returning clause.
36 +
37 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
38 +   buffer overhead and avoids problem when refresh query has a different column
39 +   count to select query i.e. incorrectly changing number of columns.
40 +
41 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
42 +
43 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
44 +    string. Note that the Version property returns an InterBase compatible version string.
45 +
46 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
47 +
48 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
49 +
50 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
51 +   This is for compatibility with Firebird 5 where Update...Returning can return
52 +   a cursor.
53 +
54 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
55 +
56 + 1. Add try-..except check when initially loading library in IDE. This should
57 + ensure that IDE continues to load even when a failure occurs in IBX load
58 + library.
59 +
60 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
61 +   hence will correctly detect end of the outer containing block when the block
62 +   contains a SELECT ... CASE ... END construct.
63 +
64 + 3. IBExtract: some further tidying up to remove extraneous white space.
65 +
66 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
67 +   errors when extra elements are added to DB.TFieldType.
68 +
69 + 5. IBUpdate: updated to reflect changes to ISQLParam.
70 +
71 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
72 +
73 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
74 +
75 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
76 +
77 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
78 +
79 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
80 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
81 +
82 + 2. TIBSQL: Batch Update/Insert support added.
83 +
84 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
85 +   is no longer automatically converted to upper case when it is syntactically a
86 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
87 +   as CREATE PROCEDURE "iCASE".
88 +
89 +   There could be a backwards compatibility issue when the StoredProcName was entered
90 +   manually at design time. That is not selected from the drop down list. If the
91 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
92 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
93 +   ensure that the value of the StoredProcName is all upper case, unless it was
94 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
95 +   quotes).
96 +
97 +   Note that when a stored procedure name was declared delimited in double quotes,
98 +   as in the first example above, the value of the StoredProcName property must not
99 +   include the delimiters (double quotes).
100 +
101 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
102 +   upgrade.conf was not found. This replaces silently ignoring the problem.
103 +
104 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
105 +   'Version.%.3d' and is used to generate the section header names (for a given
106 +   version no.) in the upgrade.conf file.
107 +
108 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
109 +
110 + 1. -c command line option added to fbsql example program. Used to set connection
111 +   character set.
112 +
113 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
114 +
115 + 1. Firebird 4 support added.
116 +
117 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
118 +   extended precision NUMERIC fields are supported.
119 +
120 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
121 +
122 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
123 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
124 +
125 + 5. IBExtract now supports FB4 enhancements:
126 +   - new data types as above
127 +   - Identity column extensions
128 +   - Default user role
129 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
130 +   - Internal Functions
131 +
132 + 6. IBExtract: new event: OnExtractLines.
133 +
134 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
135 +
136 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
137 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
138 +
139 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
140 +   format for rendering a time zone.
141 +
142 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
143 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
144 +
145 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
146 +    IIBGUIInterface and IIBTimerInf respectively.
147 +
148 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
149 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
150 +
151 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
152 +    truncated to its fixed character width rather than being right padded with
153 +    white space to the maximum data size.
154 +
155 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
156 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
157 +    also empty.
158 +
159 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
160 +
161 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
162 +    connect string. The database name is extracted from the connect string.
163 +
164 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
165 +
166 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
167 +
168 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
169 +    not being present as required.
170 +
171 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
172 +    version that can be customised to work with other database drivers.
173 +
174 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
175 +    unnecessary CR at end of line on Unix platforms.
176 +
177 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
178 +    seconds in order to reduce risk of message loss.
179 +
180 + 23. ISQLMonitor: read and write count statistics now available via:
181 +      property TIBSQLMonitor.ReadCount;
182 +      IIBSQLMonitorHook.GetWriteCount: integer;
183 +
184 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
185 +
186 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
187 +
188 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
189 +    number of UTF8 characters exceeds the string size then string is truncated
190 +    to the maximum string size. This is  usually a problem with fixed width columns
191 +    right padded with white space.
192 +
193 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
194 +    If SQLFiltered is set then when a dataset is opened, each line in the
195 +    SQLFilterParams property is assumed to be a SQL condition clause and
196 +    ANDed into the Where clause of the SQL Select statement provided as a
197 +    dataset property. Each such SQL condition thus acts as an additional filter
198 +    on the dataset.
199 +
200 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
201 +    side filters).
202 +
203 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
204 +   text matches complete entry.
205 +
206 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
207 +   dataset are active (avoids risk of access violation if master is inactive)
208 +
209 + 6. TIBEvents: Registered property can now be set at design time even if database not open
210 +
211 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
212 +   This should prevent "spillover" of events between sessions.
213 +
214 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
215 +   This should ensure that the internal buffer is set up correctly and avoids
216 +   a duplicate initial row.
217 +
218 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
219 +   That is, the DataSize should be the field size * character set width. The
220 +   value returned by DataSize is now the same as the Dataset buffer size reserved
221 +   for the field.
222 +
223 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
224 +
225 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
226 +    and vice-versa. This may result in an exception being raised (correctly) for
227 +    older programs when using dataset fields added to a form and the database has been
228 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
229 +    In such cases, the field needs to be deleted in the IDE fields editor and then
230 +    added back in.
231 +
232 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
233 +    false if query contains only white space and not just empty.
234 +
235 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
236 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
237 +    is cancelled.
238 +
239 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
240 +    called on a null field.
241 +
242 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
243 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
244 + set.
245 +
246 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
247 +    a cached update is applied and an exception is raised.
248 +
249 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
250 +
251 + 17. Console Mode Local Database support: backup/restore should now work correctly.
252 +
253 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
254 +    possible and an exception raised.
255 +
256 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
257 +    below this version no. and upgrade not possible.
258 +
259 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
260 +
261 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
262 +    not SQL Identifiers are now supported.
263 +
264 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
265 +    passed to the Firebird engine for execution.
266 +
267 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
268 +    is made to scroll back.
269 +
270 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
271 +
272 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
273 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
274 +
275 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
276 +   validated. If no match is found in the list of field names and the database has
277 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
278 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
279 +
280 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
281 +   with fpc 3.2.
282 +
283 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
284 +
285 +
286 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
287 +   and is used to override the default settings in the client side "firebird.conf" This
288 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
289 +   Each line of the string list should be a setting in the same format as "firebird.conf".
290 +   For example "WireCompression = true" in order to request wire compression on the client side.
291 +
292 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
293 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
294 +   also require a compatible setting in the server side "firebird.conf". For example
295 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
296 +   compression to be used.
297 +
298 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
299 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
300 +   ibx/examples/dbinfo for examples of how to display this information.
301 +
302 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
303 +   is a "convenience" property. If set the "WireCompression=true" is added to the
304 +   ConfigOverrides. If unchecked then this setting is removed.
305 +
306 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
307 +   not "INT64".
308 +
309 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
310 +   These are:
311 +    property TimestampFormat: string;
312 +    property DateFormat: string;
313 +    property TimeFormat: string;
314 +
315 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
316 +   DATETIME and TIME. The format strings use the standard FPC date/time format
317 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
318 +
319 +   If any of the above properties are set to an empty string, then the locale default
320 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
321 +   locale default is extended by appending '.zzz' to include milliseconds.
322 +
323 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
324 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
325 +
326 + 5. New published property for TIBCSVDataOut:
327 +     property QuoteStrings: boolean (default true)
328 +
329 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
330 +   used to delimit each and every string in the output.
331 +
332 + 6. New published properties for TIBCSVDataOut:
333 +    property FieldSeparator: string;
334 +    property HeaderSeparator: string;
335 +
336 +   Respectively, these provide the separator character(s) used to separate fields
337 +   in data and header rows. Both default to ','.
338 +
339 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
340 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
341 +    property OnFormatTextString;
342 +
343 +   This event handler can be used to process text strings before they are included
344 +   in the output e.g. to replace unprintable characters with alternative strings.
345 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
346 +
347 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
348 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
349 +   and without raising and exception if it does not.
350 +
351 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
352 +   consistency with SQL queries.
353 +
354 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
355 +    When true, SQL statement parameter names are parsed case sensitive. Note for
356 +    TIBDataSet only applies to Select query.
357 +
358 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
359 +    an IDE exception.
360 +
361 + 12. LocalDBSupport: initial database creation should now work correctly
362 +    when the schema source is an sql file.
363 +
364 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
365 +    when defined, this handler will be called by the internal TIBXScript during
366 +    initial database creation when the schema source is an sql file and may be used
367 +    to provide a visual indication of progress in console mode.
368 +
369 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
370 +    to true while a new local database is being created and its schema populated.
371 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
372 +    when the database is disconnected/connected during the create DB procedure.
373 +
374 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
375 +    are now always ignored and replaced by the user name and password provided as
376 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
377 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
378 +    completely ignored if this property is true.
379 +
380 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
381 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
382 +    ImageIndex and SelectImageIndex values on AddNode.
383 +
384 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
385 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
386 +    the same database connection.
387 +
388 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
389 +    if provided, this should be an conditional SQL expression suitable for
390 +    including in an SQL Select statement "where" clause. If non-empty and the
391 +    "Filtered" property is true then the SQL expression provided as the value of
392 +    the "Filter" property is "ANDed" with any existing condition statement
393 +    in the SQL statement's "Where" clause.
394 +
395 +    If the "Filter" property is set at run time, the "Filtered" property is true
396 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
397 +
398 +    The "Filter" condition may include IBX style parameters. In which case, their
399 +    value must be set by the dataset's "OnBeforeOpen" event handler.
400 +
401 +    This is a public property for TIBDataSet and TIBQuery query and intended for
402 +    use at run time.
403 +
404 +    Note: The property is a published property of TIBTable. The TIBTable functionality
405 +    is unaffected by this change.
406 +
407 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
408 +
409 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
410 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
411 +   mode apps.
412 +
413 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
414 +   statement. This avoids problems if "Execute Block" is used as the Query.
415 +
416 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
417 +   internal SQL tokeniser routines.
418 +
419 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
420 +   as a select statement, with or without CTEs.
421 +
422 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
423 +
424 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
425 +   internal SQL tokeniser routines.
426 +
427 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
428 +    being raised for valid set statements processed by a data formatter.
429 +
430 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
431 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
432 +   the path of the Firebird Library used by the database/services connection.
433 +
434 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
435 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
436 +   services connection.
437 +
438 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
439 +   or param name is not a valid SQL identifier.
440 +
441 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
442 +    view of whether the text box should be editable when no DataSource is specified.
443 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
444 +    ReadOnly is false, the text box is editable when no DataSource is specified.
445 +
446 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
447 +    the FBLIB environment variable. If you do not want to permit this then you
448 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
449 +    this setting.
