1 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
2
3 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
4 This is for compatibility with Firebird 5 where Update...Returning can return
5 a cursor.
6
7 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
8
9 1. Add try-..except check when initially loading library in IDE. This should
10 ensure that IDE continues to load even when a failure occurs in IBX load
11 library.
12
13 2. IBXScript: now recognises a CASE...END block within a stored procedure and
14 hence will correctly detect end of the outer containing block when the block
15 contains a SELECT ... CASE ... END construct.
16
17 3. IBExtract: some further tidying up to remove extraneous white space.
18
19 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
20 errors when extra elements are added to DB.TFieldType.
21
22 5. IBUpdate: updated to reflect changes to ISQLParam.
23
24 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
25
26 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
27
28 8. IBSQL: Support for scrollable cursors added (note: local databases only)
29
30 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
31
32 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
33 exception of those defined to be one byte wide e.g. DBImplementationNo.
34
35 2. TIBSQL: Batch Update/Insert support added.
36
37 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
38 is no longer automatically converted to upper case when it is syntactically a
39 SQL Identifier. This is to support the use of stored procedures defined e.g.
40 as CREATE PROCEDURE "iCASE".
41
42 There could be a backwards compatibility issue when the StoredProcName was entered
43 manually at design time. That is not selected from the drop down list. If the
44 StoredProcName is entered in mixed case and the procedure was declared e.g. as
45 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
46 ensure that the value of the StoredProcName is all upper case, unless it was
47 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
48 quotes).
49
50 Note that when a stored procedure name was declared delimited in double quotes,
51 as in the first example above, the value of the StoredProcName property must not
52 include the delimiters (double quotes).
53
54 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
55 upgrade.conf was not found. This replaces silently ignoring the problem.
56
57 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
58 'Version.%.3d' and is used to generate the section header names (for a given
59 version no.) in the upgrade.conf file.
60
61 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
62
63 1. -c command line option added to fbsql example program. Used to set connection
64 character set.
65
66 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
67
68 1. Firebird 4 support added.
69
70 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
71 extended precision NUMERIC fields are supported.
72
73 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
74
75 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
76 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
77
78 5. IBExtract now supports FB4 enhancements:
79 - new data types as above
80 - Identity column extensions
81 - Default user role
82 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
83 - Internal Functions
84
85 6. IBExtract: new event: OnExtractLines.
86
87 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
88
89 8. IBXServices: Server version no. parsing now allows any letter before major version number
90 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
91
92 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
93 format for rendering a time zone.
94
95 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
96 to convert TIME WITH TIME ZONE data type values to and from GMT.
97
98 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
99 IIBGUIInterface and IIBTimerInf respectively.
100
101 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
102 now accessible as properties of TIBDatabase and TIBTransaction respectively.
103
104 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
105 truncated to its fixed character width rather than being right padded with
106 white space to the maximum data size.
107
108 14. TIBTable.Empty table. In additional to deleting all records in the underlying
109 table, the internal buffers are now also flushed ensuring that the TIBTable is
110 also empty.
111
112 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
113
114 16. TIBXControlService descendents: DatabaseName may now be set using a database
115 connect string. The database name is extracted from the connect string.
116
117 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
118
119 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
120
121 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
122 not being present as required.
123
124 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
125 version that can be customised to work with other database drivers.
126
127 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
128 unnecessary CR at end of line on Unix platforms.
129
130 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
131 seconds in order to reduce risk of message loss.
132
133 23. ISQLMonitor: read and write count statistics now available via:
134 property TIBSQLMonitor.ReadCount;
135 IIBSQLMonitorHook.GetWriteCount: integer;
136
137 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
138
139 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
140
141 1. TIBStringField: when a string value is read from a dataset buffer, if the
142 number of UTF8 characters exceeds the string size then string is truncated
143 to the maximum string size. This is usually a problem with fixed width columns
144 right padded with white space.
145
146 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
147 If SQLFiltered is set then when a dataset is opened, each line in the
148 SQLFilterParams property is assumed to be a SQL condition clause and
149 ANDed into the Where clause of the SQL Select statement provided as a
150 dataset property. Each such SQL condition thus acts as an additional filter
151 on the dataset.
152
153 3. The Filtered property inherited from TDataset is no longer used for SQL (server
154 side filters).
155
156 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
157 text matches complete entry.
158
159 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
160 dataset are active (avoids risk of access violation if master is inactive)
161
162 6. TIBEvents: Registered property can now be set at design time even if database not open
163
164 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
165 This should prevent "spillover" of events between sessions.
166
167 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
168 This should ensure that the internal buffer is set up correctly and avoids
169 a duplicate initial row.
170
171 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
172 That is, the DataSize should be the field size * character set width. The
173 value returned by DataSize is now the same as the Dataset buffer size reserved
174 for the field.
175
176 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
177
178 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
179 and vice-versa. This may result in an exception being raised (correctly) for
180 older programs when using dataset fields added to a form and the database has been
181 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
182 In such cases, the field needs to be deleted in the IDE fields editor and then
183 added back in.
184
185 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
186 false if query contains only white space and not just empty.
187
188 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
189 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
190 is cancelled.
191
192 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
193 called on a null field.
194
195 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
196 results in an empty dataTC86 Client side Filtered Dataset 1 X
197 set.
198
199 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
200 a cached update is applied and an exception is raised.
201
202 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
203
204 17. Console Mode Local Database support: backup/restore should now work correctly.
205
206 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
207 possible and an exception raised.
208
209 19. MinimumVersionNo added to Local Database Support. Database will not open if
210 below this version no. and upgrade not possible.
211
212 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
213
214 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
215 not SQL Identifiers are now supported.
216
217 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
218 passed to the Firebird engine for execution.
219
220 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
221 is made to scroll back.
222
223 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
224
225 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
226 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
227
228 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
229 validated. If no match is found in the list of field names and the database has
230 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
231 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
232
233 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
234 with fpc 3.2.
235
236 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
237
238
239 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
240 and is used to override the default settings in the client side "firebird.conf" This
241 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
242 Each line of the string list should be a setting in the same format as "firebird.conf".
243 For example "WireCompression = true" in order to request wire compression on the client side.
244
245 Note: explicit settings in the client side "firebird.conf" appear to take precedence
246 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
247 also require a compatible setting in the server side "firebird.conf". For example
248 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
249 compression to be used.
250
251 Whether or not WireCompression or WireCrypt are in use can be checked using the information
252 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
253 ibx/examples/dbinfo for examples of how to display this information.
254
255 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
256 is a "convenience" property. If set the "WireCompression=true" is added to the
257 ConfigOverrides. If unchecked then this setting is removed.
258
259 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
260 not "INT64".
261
262 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
263 These are:
264 property TimestampFormat: string;
265 property DateFormat: string;
266 property TimeFormat: string;
267
268 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
269 DATETIME and TIME. The format strings use the standard FPC date/time format
270 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
271
272 If any of the above properties are set to an empty string, then the locale default
273 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
274 locale default is extended by appending '.zzz' to include milliseconds.
275
276 TIBCSVDataOut by default sets these properties to the empty string, while the other
277 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
278
279 5. New published property for TIBCSVDataOut:
280 property QuoteStrings: boolean (default true)
281
282 If false then strings are unquoted, otherwise, the QuoteChar property value is
283 used to delimit each and every string in the output.
284
285 6. New published properties for TIBCSVDataOut:
286 property FieldSeparator: string;
287 property HeaderSeparator: string;
288
289 Respectively, these provide the separator character(s) used to separate fields
290 in data and header rows. Both default to ','.
291
292 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
293 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
294 property OnFormatTextString;
295
296 This event handler can be used to process text strings before they are included
297 in the output e.g. to replace unprintable characters with alternative strings.
298 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
299
300 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
301 Uses "FindParam" if in order to find out if a parameter with a given name exists
302 and without raising and exception if it does not.
303
304 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
305 consistency with SQL queries.
306
307 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
308 When true, SQL statement parameter names are parsed case sensitive. Note for
309 TIBDataSet only applies to Select query.
310
311 11. IBEvents: removing a TIBEvent component from a form should no longer result in
312 an IDE exception.
313
314 12. LocalDBSupport: initial database creation should now work correctly
315 when the schema source is an sql file.
316
317 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
318 when defined, this handler will be called by the internal TIBXScript during
319 initial database creation when the schema source is an sql file and may be used
320 to provide a visual indication of progress in console mode.
321
322 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
323 to true while a new local database is being created and its schema populated.
324 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
325 when the database is disconnected/connected during the create DB procedure.
326
327 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
328 are now always ignored and replaced by the user name and password provided as
329 the login parameters for the TIBDatabase referenced from the TIBXScript. The
330 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
331 completely ignored if this property is true.
332
333 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
334 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
335 ImageIndex and SelectImageIndex values on AddNode.
336
337 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
338 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
339 the same database connection.
340
341 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
342 if provided, this should be an conditional SQL expression suitable for
343 including in an SQL Select statement "where" clause. If non-empty and the
344 "Filtered" property is true then the SQL expression provided as the value of
345 the "Filter" property is "ANDed" with any existing condition statement
346 in the SQL statement's "Where" clause.
347
348 If the "Filter" property is set at run time, the "Filtered" property is true
349 and the dataset is already open, then the dataset is closed and re-opened automatically.
350
351 The "Filter" condition may include IBX style parameters. In which case, their
352 value must be set by the dataset's "OnBeforeOpen" event handler.
353
354 This is a public property for TIBDataSet and TIBQuery query and intended for
355 use at run time.
356
357 Note: The property is a published property of TIBTable. The TIBTable functionality
358 is unaffected by this change.
359
360 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
361
362 1. Remove need to check for IsMultiThread by providing access to GUI timers via
363 IBGUIInterface. Note: master/detail delay timer does not apply to console
364 mode apps.
365
366 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
367 statement. This avoids problems if "Execute Block" is used as the Query.
368
369 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
370 internal SQL tokeniser routines.
371
372 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
373 as a select statement, with or without CTEs.
374
375 5. IBSQLParser: parser now recognises the "ROWS" clause.
376
377 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
378 internal SQL tokeniser routines.
379
380 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
381 being raised for valid set statements processed by a data formatter.
382
383 8. New published property for TIBDatabase and TIBXServicesConnection. This is
384 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
385 the path of the Firebird Library used by the database/services connection.
386
387 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
388 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
389 services connection.
390
391 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
392 or param name is not a valid SQL identifier.
393
394 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
395 view of whether the text box should be editable when no DataSource is specified.
396 TIBLookupComboEditBox has been updated to workaround this problem. As long as
397 ReadOnly is false, the text box is editable when no DataSource is specified.
398
399 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
400 the FBLIB environment variable. If you do not want to permit this then you
401 must modify the Register procedure in the design/IBDBReg.pas unit to remove
402 this setting.
403
404 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
405
406 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
407 Utf8EscapeControlChars
408
409 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
410
411 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
412 all previous copies of the IBX source code tree before installing this release.
413
414 The IBX packages used by most users have not changed, with one exception. The
415 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
416 to use the IBServices unit in your applications, please add the iblegacyServices
417 to the list of dependencies. To do this, open the Project Inspector and select
418 Add->New Requirement and select "ibLegacyServices" from the list of available
419 packages.
420
421 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
422 the IBServices unit providing what is intended to be a clearer and easier to
423 use set of IB Services components. See Chapter 10 of the IBX User Guide for
424 more information and the guide to "Firebird Service Management Using IBX".
425 As indicated above, the legacy services components are still available and
426 provided in a separate package. There is no need to update working applications
427 using the older versions except for an additional package dependency.
428
429 2. The IBX packages and source code tree have been re-organised in an attempt to
430 finally get rid of the "duplicate ppu" warnings. This re-organisation should
431 not affect existing users. Section 2.3 of the IBX User Guide describes the
432 new set of IBX packages.
433
434 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
435 updated to use the new Services API components.
436
437 4. The iblocal package has been updated to use the new Services API components.
438
439 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
440 TIBXSecurityService. It had been wrongly classified in the previous version
441 as a per database configuration item. It is global to a server and hence
442 correctly positioned as part of the Security Package. In the DBAdmin example,
443 the setting has moved to the mappings page.
444
445 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
446 are ignored.
447
448 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
449 closed before the database is dropped. Before and After Disconnect event handlers
450 are also fired.
451
452 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
453 is started and not just the first time.
454
455 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
456 depenendency with comp type.
457
458 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
459
460 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
461 then this is recognised and not ignored.
462
463 12. TIBDataSet, TIBQuery, TIBTable: additions:
464 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
465 function GetPerfStatistics(var stats: TPerfCounters): boolean;
466 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
467
468 GetRowsAffected returns the affected row counts from the last insert/update/delete
469 if EnableStatistics = true then GetPerfStatistics returns the current stats
470 counters for the select query. Note: stats accumulate after each fetch from
471 the database. To get total query cost after open, call the "Last" method
472 and then GetPerfStatistics.
473
474 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
475
476 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
477 in parenthesises.
478
479 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
480 SQL identifiers are always delimited by double quotes. If false, then they are
481 only delimited if the identifier is a reserved word, contains lower case or special
482 characters. Set this property to true to retain previous behaviour.
483
484 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
485 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
486
487 16. TIBDataSet, TIBQuery, TIBTable: addition:
488 property MasterDetailDelay: integer {defaults to zero}
489
490 When non-zero and the dataset is a detail table referencing a master table
491 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
492 then a synchronisation delay is added (in milliseconds) between the master
493 row changing and the detail dataset being re-opened. If the master dataset
494 is scrolled before the delay expires then the delay is reset. This can be used
495 to avoid performance overheads when scrolling through a large master dataset.
496
497 Note: uses fptimer and hence requires a thread manager. Under Linux the
498 chreads unit must be included in your project. TTimer is not used in order
499 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
500
501 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
502 with Extract Option eoDatabase.
503
504 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
505 When a deLayoutChanged event is reported on the ListSource dataset, the
506 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
507 relationship with the control's datasource (master).
508
509 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
510
511 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
512 stubs. Pedantic fix really, as procedures output in dependency order anyway.
513
514 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
515 DDL (Firebird 3 and later only).
516
517 22. TIBLookupComboBox Autocomplete Fixes:
518 i. Only appended text is now selected after autocomplete.
519 ii. Uppercase keys no longer ignored for autocomplete.
520 iii. Retain Prefix case is now honoured correctly.
521 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
522 before autocomplete performed. i.e. behaviour now the same as when
523 no DataSource assigned.
524
525 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
526 between SQL statements.
527
528 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
529 ObjectNames are converted to upper case before matching against metadata object
530 names, unless the objectname is delimited by double quotes, in which case, the
531 double quotes are removed and the remaining string is used (unmodified) to match
532 against the metadata object name.
533
534 If true then the ObjectName is used as is without modification and matched
535 against the metadata object name. No attempt is made to remove double quotes.
536
537 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
538 with eoTrigger, these extract types can be used to select only Database Triggers,
539 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
540
541 26. TIBXScript: If an exception occurs during the processing of a statement, the
542 statement separate character is now reset to the default (';').
543
544 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
545
546 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
547 a commit or reconnect statement and instead activated only when next SQL statement
548 is executed.
549
550 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
551
552 30. TIBXScript: case insensitive regex now used when matching statements instead of
553 converting statement to upper case.
554
555 31. TIBExtract: metadata comments now supported. New published property
556 IncludeMetaDataComments (default true). If true then metadata comments included
557 in extracted DDL. New Extract Object member eoComments. This may be used with
558 ExtractObject method to list all metadata comments.
559
560 32. TIBExtract: ListObjectNames method added.
561
562 33. Updated Database component editor to support additional connection string
563 types.
564
565 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
566
567 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
568 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
569 RELEASE.
570
571 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
572
573 1. IBExtract: Identity columns - add additional check for null column for generator name.
574
575 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
576 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
577 information). However, this is also a very useful mechanism for returning updated computed by
578 column values. Values returned as a result of executing an Insert or Update statement
579 replace existing values in the current row for each corresponding column.
580
581 Previously, if a dataset's select query included read only (computed by) fields then
582 an automatic row refresh was performed after an insert or update query had been processed,
583 irrespective of the setting of the "ForcedUpdates" property. This has changed such
584 that an automatic refresh is no longer performed if an insert or update query contains
585 a returning clause that updates one or more fields on the current row. A full row
586 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
587 field values and the select query contains read only fields. Use of Insert/update
588 returning should be significantly more efficient than executing a refresh query.
589
590 This behaviour change is intended to be backwards compatible and there should be no need to change
591 existing programs, other than to improve performance by using the new capability.
592
593 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
594 they are called when the dataset row is being deleted, there is no value in
595 updating the current record from the query result. Instead, a new event handler
596 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
597 an OnDeleteReturning event handler is provided then it is called with the IResults returned
598 by the query. The event handler can then interrogate the query results and
599 perform whatever action is necessary. For example to confirm, to the user,
600 the deletion of a row with the returned values.
601
602 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
603 any Computed By or Identity Columns. The IBTables example has been updated to
604 illustrate the computation of the employee Full Name on update.
605
606 5. TIBTable: The GeneratorField property is now published.
607
608 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
609 When InsertSQL is generated, the Identity columns are not included in the list of values to
610 be inserted. A RETURNING clause is added to the insert statement to return the value of
611 each Identity column after the insert is executed.
612
613 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
614 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
615 Insert..Returning clause.
616
617 8. TIBGenerator: small performance improvement by not preparing query each time
618 a new value is generated.
619
620 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
621
622 10. Property editors will now sync table name to a System Table when "Include System
623 Tables" is selected and the query is for a System Table.
624
625 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
626 values are no longer converted to milliseconds from TDateTime and then back again
627 to TDateTime (the conversion to milliseconds is the default TDataset approach).
628
629 12. Property Editors handling of Stored Procedures.
630 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
631 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
632 query).
633 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
634
635 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
636 can be used to select a package. If non-empty, the stored procedure name is
637 expected to be a stored procedure defined in the specified package and the
638 generated SQL will be as required for a stored procedure located in a package.
639
640 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
641 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
642 which a stored procedure can be selected. With no package name selected, non-package
643 stored procedures are listed.
644
645 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
646 for password on reconnect.
647
648 16. TIBDatabase: use IAttachment for connection default character set id, code page
649 and character set name.
650
651 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
652 DB info lookups"
653
654 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
655
656 19. Add a property Editor for TIBUpdate.RefreshSQL.
657
658 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
659 parameters. This stops an exception being raised when the field cannot be
660 located in the record buffer.
661
662 21. Property Editors now automatically include System Tables when opened and when the query table
663 is a System Table.
664
665 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
666 This avoids errors due to a stale SQRB or SRB being used for the next query.
667
668 23. IBServices: Service attach parameters now include "expected_db". This is used to
669 add the SPB item isc_spb_expected_db. This names a database using
670 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
671 database. examples/services re-written to illustrate use of "expected_db".
672
673 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
674 This avoids truncated backups when the server returns a timeout (busy) response.
675
676 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
677
678 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
679 databasenames. These are respectively expanded to the local system's temp directory
680 (including trailing delimiter) or to a prescribed data directory (including
681 trailing delimiter). Under Unix systems the data directory is a hidden directory
682 in the user's home directory. The hidden directory name is either the string returned
683 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
684 Under Windows, the directory is the same as the Data Directory as decribed
685 above but instead prefixed by the User's application data path. These may be
686 used to improve application portability for Personal Databases.
687
688 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
689 this has not worked for a long time and is not useful either. FieldDefs should be
690 managed using the Fields Editor as with any other dataset. To access the fields
691 editor for a TIBTable component, double click on the component. The fields editor
692 is then displayed.
693
694 28. TIBDatabaseInfo: new properties/function
695 * DateDBCreated (returns date/time database created)
696 * TransactionCount (returns no. of active transactions)
697 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
698 * PagesFree (Firebird 3 or later)
699 * PagesUsed (Firebird 3 or later)
700 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
701 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
702
703 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
704
705 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
706
707 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
708 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
709
710 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
711 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
712 firing during backup and restore.
713
714 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
715 for verbose output using the new property "StatisticsRequested".
716 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
717
718 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
719
720 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
721 palette. This uses the online validation feature added in Firebird 2.5. The
722 services's properties enable inclusion/exclusion of tables and indexes using
723 regular expressions. See.
724 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
725
726 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
727 option on a database.
728
729 37. TIBCustomService: Assign method implemented to allow copying of service login
730 context between service API components. "Detach" method now only detaches
731 service when last reference to the service interface detaches. Tidy up of
732 code for SetActive and Attach methods including password hiding.
733
734 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
735 and used to determine the auth method and protocol used for the connection.
736
737 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
738 a Create Database Statement generated by IBX.
739
740 40. All IBServices now have an additional published property "PortNo". This may
741 be set to a non-standard port number when necessary. If zero then the default
742 port number is used.
743
744 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
745 and not just the mouse.
746
747 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
748
749 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
750 image index and selected image index for each node to be set from a database field.
751
752 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
753 then database schema includes grants to all users. If not present then the
754 only user grants included are those to User PUBLIC.
755
756 45. TIBTreeView: performance improvement. When expanding include both expanded node
757 and child nodes in dataset.
758
759
760 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
761
762 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
763 changes.
764
765 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
766 Bug could result in truncated multi-byte character set values.
767
768 3. Changes consequential on moving fbintf character set utility functions from
769 IFirebirdAPI to IAttachment.
770
771 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
772
773 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
774 results in autocomplete ignoring prefix text.
775
776 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
777 entering a new name into the text box.
778
779 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
780 Firebird rather than recomputing it.
781
782 8. Property Editor positioning tidy up: All IBX Property editors should now be
783 screen centre. Previously some were "poDesigned" which may be inappropriate
784 for multi monitor desktops.
785
786 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
787
788 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
789 a transaction and always reset the object.
790
791 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
792
793 13. TIBXScript: Allow for override of database filename in Create Database statements.
794
795 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
796 to a gbak format archive.
797
798 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
799
800 16. IBLocaldb: Drop database if error creating an empty database.
801
802 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
803 unless selected node not in current dataset.
804
805 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
806 to TIBCustomService, and IBlocalDB code tidy up.
807
808 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
809 behaviour due to uninitialised variable.
810
811 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
812 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
813
814 21. IBSQL: When Database changed ensure that all resources are freed.
815
816 22. IBCustomDataset: When database changed ensure that queries an unprepared.
817
818 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
819 * Line Wrap on SQL Token boundaries (on user command)
820 * auto-complete table names in drop down list of table names
821 * Double click on tablename or field name adds to SQL text
822
823 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
824
825 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
826 TVariantArray. Seems to avoid memory corruption in Windows (probably a
827 workaround for a problem in fpc 3.0.4 win64).
828
829 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
830
831 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
832
833 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
834
835 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
836 include remote system name.
837
838 2. TIBExtract: No longer include comment header and COMMIT statement for empty
839 tables when data included in output.
840
841 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
842 and timing information to be written to stdout. This may be used to locate
843 performance bottlenecks.
844
845 4. SQLParser: only call "OnChanging" event handler when value is different.
846
847 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
848
849 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
850 that BindFields is called when the query is next activated. Avoids FieldName
851 not found error.
852
853 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
854 purpose and allows the programmer to define any action they want for Update, Insert
855 or Delete. This may be complex SQL (similar to a Trigger), application specific
856 filtering of updates, or use of statements such as Grant or Revoke instead of
857 normal DML. See User Manual for more information.
858
859 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
860
861 1. TIBEvents: Fix uninitialised variable that could result in lost events.
862
863 2. TIBExtract: Added support for FB3 "USAGE" privilege.
864
865 3. TIBExtract: data formatted as Charset set "octets" is now output using
866 hexadecimal notation.
867
868 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
869 using a simple XML format.
870
871 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
872 grants to these objects.
873
874 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
875 dependency problems restoring complex databases.
876
877 7. TIBXScript: This component has been restructured to allow for the processing of
878 embedded XML in INSERT statements and to support interactive sources in addition
879 to non-interactive data sources such as files.
880
881 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
882
883 9. TIBXScript: ISQL compatiable Set statements are now supported:
884 SET SQL DIALECT
885 SET TERM
886 SET AUTODDL
887 SET BAIL
888 SET ECHO
889 SET COUNT
890 SET STATS
891 SET NAMES <character set>
892
893 10. IBVersion unit added to hold current IBX Version Number information.
894
895 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
896 and domain definitions.
897
898 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
899 fully supported.
900
901 13. TIBExtract: when a database dump includes data, the generator values are now also set.
902
903 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
904
905 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
906
907 See also doc/IBX4LazarusGuide.pdf for important information on
908 upgrading to IBX2.
909
910 1. Size property of TIBStringField is now the width in characters of the field
911 and not the byte length. This applies only to multi-byte character sets such
912 as UTF8. The original approach aligned with TStringField. However, the TStringField
913 code is not recognised as a bug and hence this change to align the behaviour.
914 The TStringField change is expected in fpc 3.2.0.
915
916 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
917 true (default) then Size property value saved in the lfm is ignored. Size is
918 always set from the dynamic information read from the database. It is unclear
919 why anyone would want to override this and set Size to false.
920
921 3. ibxscript: should now handle correctly a Case..End statement within a procedure
922 block.
923
924 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
925 exist when an attempt is made to connect to it (run time only) then an attempt
926 is made to create the database.
927
928 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
929 has been successfully created as a result of a call to CreateDatabase or when
930 creating a database after it was found not to exist.
931
932 6. DBControlGrid: a race condition could result in the wrong row image being
933 written to the cache. This has been avoided by a trip round the message
934 loop before rendering the row image.
935
936 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
937 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
938 known to risk corrupt rendering of row images when the control is first
939 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
940 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
941
942 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
943 a TDateEdit control located on an editor panel.
944
945 9. TIBExtract: brought up-to-date plus many bug fixes.
946
947 10. DBControlGrid: Removed memory leak when updating rows.
948
949 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
950
951 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
952
953 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
954 when target codepage is CP_NONE. This is a workaround for
955 http://bugs.freepascal.org/view.php?id=30622.
956
957 2. DBLog option removed from TIBStatisticalService - not supported by server
958 since Firebird 1.5.
959
960 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
961 similar.
962
963 4. IBCodePage: updated mapping between codepages and character id.
964
965 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
966 Firebird. Character sets with a char width of two are not UTF16.
967
968 6. Strings received from the database are now always transliterated into UTF8
969 regardless of the database character set or connection character set. This
970 is for compatibility with the LCL.
971
972 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
973
974 1. IBBlob: Defer reading of blob until read method called. This avoids having to
975 read in an entire blob just to get the size of the blob. General performance
976 improvement when opening datasets containing blobs.
977
978 2. Clearing a Blob now sets the corresponding field's modified flag.
979
980 3. IBLookupCombo: When not performing auto-complete, original query sort order
981 is now used.
982
983 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
984 determined.
985
986 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
987
988 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
989 lazarus 1.6.0
990
991 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
992 compilation error.
993
994 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
995
996 1. No character set specified for connection: when a text blob is retrieved, the
997 character set is determined by looking up the native character set using then
998 Firebird API. Otherwise a text mode blob is assumed to have the same character
999 set as the connection.
1000
1001 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1002 for Login Dialog returing a change to the database path.
1003
1004 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1005 to be changed from that given in the TIBDatabase/TIBServer component and for the
1006 entered value to be saved on a project specific basis (design time only).
1007
1008 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1009 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1010 Otherwise, it sets the column text to the selected ListField Value.
1011
1012 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1013 column width.
1014
1015 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1016 and a case insensitive search is requested.
1017
1018 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1019 or column ListSource.
1020
1021 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1022 unprepare) when closing and the text has not changed.
1023
1024 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1025 Less likely to cause a cursor re-use error on Windows.
1026
1027 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1028 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1029
1030 11. TIBTreeView: Guard against nil destination on record changed
1031
1032 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1033 string type with the code page set to reflect the returned field encoding after
1034 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1035 earlier versions.
1036
1037 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1038 will now result in transliteration to the code page specified for the Firebird driver
1039 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1040
1041 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1042 is ignored and the lc_ctype value, when the database is opened, is set to align with
1043 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1044 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1045 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1046 the GETACP is used to determine the Windows code page.
1047
1048 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1049 name used as the lc_ctype when the database was opened. Only valid while the
1050 Database is connected.
1051
1052 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1053 id that corresponds to the DefaultCharSetName.
1054
1055 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1056
1057 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1058 path is given and database attach fails due to access permission issues on the
1059 temp directory or security database, then the attach is retried with "localhost:"
1060 prefixing the databasename. This should avoid problems when the database has to
1061 be accessed by a local (e.g. classic) server and libfbembed is used.
1062
1063 2. Windows: revised search order for Firebird DLL:
1064 i. The Firebird Embedded Server in the application Directory.
1065 ii. If the FIREBIRD environment variable is set then the directory this
1066 points to is searched for the FB Client DLL and then then underlying
1067 "bin" directory.
1068 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1069 is used to locate the Firebird installation directory and the underlying
1070 "bin" directory is searched for the FB Client DLL.
1071 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1072 are searched for the FB Client DLL.
1073 v. The PATH Environment variable is used to search for the FB Client DLL.
1074 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1075
1076 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1077 See doc/readme.scriptengine and example applications.
1078
1079 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1080 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1081 See dpc/readme.localdatabase and example applications.
1082
1083 5. IBDynamicGrid: Reordering on column header click should now also work for
1084 dynamic columns.
1085
1086 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1087 between incrementing/decrementing the lock count and signalling the event.
1088
1089 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1090
1091 1.3.2 was never formally released and only made available as beta copies.
1092
1093 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1094
1095 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1096
1097 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1098
1099 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1100 i.e. when it is a calculated field
1101
1102 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1103 This problem was due to a race condition between recalculating row heights and
1104 determining which row was selected by the mouse click. The row height calculation
1105 is now deferred by an extra trip round the message loop allowing the row to
1106 be always calculated on the current grid layout rather than risking it being
1107 calculated on the grid layout after the expanded row has been shrunk.
1108
1109 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1110 Windows.
1111
1112 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1113 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1114 to be determined at runtime. See doc/readme.charactersets.html.
1115
1116 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1117 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1118
1119 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1120 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1121 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1122
1123 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1124 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1125 implies no truncation.
1126
1127 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1128
1129 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1130 (avoids "Not in Edit Mode" error).
1131
1132 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1133
1134 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1135 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1136
1137 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1138
1139 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1140
1141 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1142
1143 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1144
1145 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1146
1147 1. OnCloseUp Event Handler added to TDBLookupProperties
1148
1149 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1150 problem with row size when exception is called.
1151
1152 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1153
1154 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1155 in a TCustomComboBox and ignores return key if in a TCustomMemo
1156
1157 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1158 keyed in i.e. when autocomplete not performed
1159
1160 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1161 console mode applications with all LCL required functions (builtin dialogs and
1162 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1163 not included in your project, IBX should compile and link with a console mode program.
1164 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1165 console mode application or the IDE will automatically assume that your
1166 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1167
1168 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1169 to use the built in dialogs and cursor management. IBDialogs is
1170 included by default if "ibexpress" is in your project source's "uses" clause.
1171 This should be the case for all projects created through the IDE. This is why
1172 you do not want to add the ibexpress package to console mode applications. The
1173 ibexpressconsolemode package has been created to allow console mode programs
1174 to avoid adding LCL dependencies when using IBX, while still having the
1175 unit search paths set up correctly.
1176
1177 Existing users should check to ensure that the "ibexpress" unit is included in
1178 each project's source file (*.lpr).
1179
1180 You may find that in order for the IDE to recognise that ibexpressconsolemode
1181 exists, you have to first open the package in the IDE and then close it. This
1182 adds it to the most recently accessed packages list. To make it permanently
1183 available, add the package name to lazarus' staticpackages.inc file.
1184
1185 Thanks to Julio Jiménez for suggesting support of console mode.
1186
1187 7. SQL Parser can now accept quoted strings that include new lines
1188
1189 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1190 of text on start of edit. This is particularly useful when tabbing to a
1191 column and then inserting text.
1192
1193 9. New Examples provided for IB Services and ISQLMonitor.
1194
1195 10. Fix error when writing to blob streams that recorded only the last buffer
1196 write in the blob stream. In most cases, this did not cause a problem as the
1197 IB Blob Stream is written in a single write. However, with the TDBImage, write
1198 of a graphic type prefix was lost which caused a problem when the image could
1199 not be automatically recognised.
1200
1201 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1202 already open" errors due to random numbers used for the cursor name being identical.
1203
1204 12. IBTable: corrected error that could result in an "Index out of bounds" error
1205 when opening the table and the Primary Key is the last or only column in the
1206 table. Thanks to Rick Hoover for the fix.
1207
1208 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1209 of "UTF-8", and update list of available database character sets. Existing
1210 users should check the current lc_ctype setting in their applications.
1211
1212 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1213
1214 1. Firebird Services: avoid List Index error when opening a service with an
1215 empty Params property.
1216
1217 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1218 Link now set up in Loaded method - avoids occasional failure to apply
1219 SQL markup on initial open.
1220
1221 3. "Employees" example performance improvements when scrolling.
1222
1223 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1224 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1225 random image cached).
1226
1227 5. DBControlGrid: Should now react to changes in panel height at run time.
1228
1229 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1230 even when further rows exist.
1231
1232 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1233 always be derived from panel height and setting this property can cause confusion.
1234 Note for existing projects: to avoid a missing property error at run time,
1235 each form using the DBControlGrid must be opened, updated and saved in the IDE
1236 in order to remove the property value from the lfm.
1237
1238
1239 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1240
1241 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1242 call Prepare before setting parameter values.
1243
1244 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1245
1246 3. Code tidyup and more robust handling of dsql information result vector.
1247
1248 4. Support for centralised handling of transaction status changes. TIBTransaction
1249 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1250 and "AfterExecQuery". The first three are called after the same event is called
1251 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1252 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1253 enable monitoring of transaction status changes for a given transaction to be
1254 handled in a single place. For example, when a change to the dataset occurs
1255 an indicator can be set that shows the user that in order to save changes,
1256 the transaction should be committed. Rather than doing this per dataset, this
1257 can now be done per transaction.
1258
1259 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1260 the dataset is scrolled. However, any changes to the current row are, by default,
1261 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1262 have a new property "DataSetCloseAction" that adds automatic posting of changes
1263 on dataset close. If this property is set to dcDiscardChanges (default) then the
1264 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1265 then IBX will attempt to post any unsaved changes before the dataset is closed
1266 (and after the BeforeClose event handler is called). The exception is when the
1267 dataset is being closed as a result of a transaction rollback. In this case,
1268 no action is taken and any unsaved changes are discarded. This avoids both
1269 unnecessary overhead and the risk that a validation error may occur in the Post
1270 raising an exception and thereby preventing a rollback.
1271
1272 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1273 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1274 width. Display Widths are now corrected by dividing by the max byte width per character.
1275 For UTF8 character sets, the byte width is four and hence the Display Width will be
1276 the byte width divided by 4. The byte width of each character set is determined
1277 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1278 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1279
1280 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1281
1282 8. IBLookupComboEditBox: List should now always be restored to full list when the
1283 control loses focus. Default Key press default interval reduced to 200ms.
1284
1285 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1286 when dataset rows are less than visible rows.
1287
1288 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1289 does not exist or DataSet is empty. More responsive on dataset open. New event
1290 OnRestorePosition. Column sort disabled if no header row.
1291
1292 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1293 while dataset state is dsInsert. Avoids posting errors.
1294
1295 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1296 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1297
1298 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1299
1300 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1301 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1302 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1303 always "posts" the current record regardless or whether or not it may be more appropriate
1304 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1305 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1306 as the first action of the "Post" method and allows the handler to convert the Post
1307 into a Cancel if that is the appropriate action on moving to a different row. This is
1308 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1309 raised here, but it may still be more appropriate to validate a post and signal
1310 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1311
1312 15. On Unix derived systems, the Firebird library name can now be given as a colon
1313 separated list. Each library name on the list is tried in turn, in left to right
1314 order with the first found being used as the firebird library. By default, on Linux,
1315 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1316 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1317
1318 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1319 then it will still attempt to access the database via the Firebird Server and will
1320 require a username and password. If only the pathname is given, then the username
1321 and password should be omitted and the unix file permissions are used to grant
1322 access.
1323
1324 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1325
1326 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1327 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1328 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1329 corresponds to a row of the linked DataSource. Any data aware control on the
1330 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1331
1332 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1333 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1334 takes place during database access. This may be useful when there are performance issues with
1335 the change of cursor. Setting the property to false suppresses the change of cursor.
1336
1337 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1338 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1339 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1340 making all changes permanent immediately rather than when the transaction is explicitly
1341 committed.
1342
1343 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1344 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1345
1346 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1347
1348 Development version only.
1349
1350 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1351
1352 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1353 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1354 "Where" and "Having" clauses to implement user specified filters of arbitrary
1355 complexity.
1356
1357 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1358 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1359 These are:
1360
1361 - TIBLookupComboEditBox
1362 - TIBDynamicGrid
1363 - TIBTreeview
1364
1365 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1366 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1367 to revise the available list and restrict it to items that are prefixed by the
1368 typed text (either case sensitive or case insensitive). Autoinsert allows a
1369 newly typed entry to be added to the list dataset and included in the available
1370 list items.
1371
1372 TIBDynamicGrid is a TDBGrid descendent that provides for:
1373 - automatic resizing of selected columns to fill the available row length
1374 - automatic positioning and sizing of a "totals" control, typically at the
1375 column footer, on a per column basis.
1376 - DataSet resorting on header row click, sorting the dataset by the selected column.
1377 A second click on the same header cell reversed the sort order.
1378 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1379 is automatically expanded and a panel superimposed on it. The panel can have any
1380 number of child controls, typically data aware controls with the same datasource
1381 as the grid allowing for editing of additional fields and more complex editors.
1382 - Reselection of the same row following resorting.
1383 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1384 Its properties are specified on a per column basis and allows for one or more
1385 columns to have their values selected from a list provided by a dataset.
1386 Autocomplete and autoinsert are also available. The existing picklist editor
1387 is unaffected by the extension.
1388
1389 TIBTreeView is a data aware TCustomTreeView.
1390
1391 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1392 zero scale will no longer return an error. An Int64 will be returned instead.
1393
1394 4. TIBTransaction now has events for Before and After Transaction End and a new function
1395 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1396
1397 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1398 repeated multiple times.
1399
1400 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1401 check used to get in the way of using Stored Procedures, and "Update or Insert"
1402 statements.
1403
1404 7. Insert, Modify and Delete property Editors now support Query Generation from
1405 Stored Procedures.
1406
1407 8. Three new examples illustrate the use of the new IB Controls

1410 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1411
1412 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1413 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1414 Gabor Boros for reporting this problem and for testing the improvements).
1415
1416 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1417 See readme.field+param.names in the doc folder.
1418
1419 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1420 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1421
1422 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1423
1424 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1425 actions.
1426
1427 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1428 thanks to Yuriy Kopnin for pointing this out).
1429
1430 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1431
1432 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1433 for both fields and parameter setting.
1434
1435 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1436 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1437
1438 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1439 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1440
1441 11. TIBTable now has a property editor for "MasterFields"
1442
1443 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1444 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1445
1446 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1447 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1448

1450 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1451
1452 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1453
1454 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1455
1456 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1457 it is null. This allows for alternative user defined setting of the generator
1458
1459 Many thanks to Julio Jiménez for this fix
1460
1461 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1462 and suggests that the user may have forgotten to install it.
1463
1464 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1465
1466 1. Conditional compilation used to limit registration of TIntegerField to
1467 Lazarus versions less than 1.1
1468
1469 2. When a database connection is created, character set is now by default set
1470 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1471 1250 to 1254.
1472
1473
1474 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1475
1476 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1477
1478
1479 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1480
1481 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1482 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1483
1484 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1485 package is changed to do this (which it should do).
1486
1487 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1488
1489 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1490
1491 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1492
1493 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1494
1495 4. Property editors should now correctly resize.
1496
1497 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1498 (restored original functionality)
1499
1500 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1501 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
