Line File contents
1 IBX Change Log version (2.4-0 Build 12473) Wed, 17 Feb 2021 10:49:57 +0000
2
3 1. Firebird 4 support added.
4
5 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6 extended precision NUMERIC fields are supported.
7
8 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9
10 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12
13 5. IBExtract now supports FB4 enhancements:
14 - new data types as above
15 - Identity column extensions
16 - Default user role
17 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18 - Internal Functions
19
20 6. IBExtract: new event: OnExtractLines.
21
22 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23
24 8. IBXServices: Server version no. parsing now allows any letter before major version number
25 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26
27 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28 format for rendering a time zone.
29
30 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31 to convert TIME WITH TIME ZONE data type values to and from GMT.
32
33 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34 IIBGUIInterface and IIBTimerInf respectively.
35
36 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37 now accessible as properties of TIBDatabase and TIBTransaction respectively.
38
39 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40 truncated to its fixed character width rather than being right padded with
41 white space to the maximum data size.
42
43 14. TIBTable.Empty table. In additional to deleting all records in the underlying
44 table, the internal buffers are now also flushed ensuring that the TIBTable is
45 also empty.
46
47 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48
49 16. TIBXControlService descendents: DatabaseName may now be set using a database
50 connect string. The database name is extracted from the connect string.
51
52 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53
54 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55
56 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57 not being present as required.
58
59 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60 version that can be customised to work with other database drivers.
61
62 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
63
64 1. TIBStringField: when a string value is read from a dataset buffer, if the
65 number of UTF8 characters exceeds the string size then string is truncated
66 to the maximum string size. This is usually a problem with fixed width columns
67 right padded with white space.
68
69 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
70 If SQLFiltered is set then when a dataset is opened, each line in the
71 SQLFilterParams property is assumed to be a SQL condition clause and
72 ANDed into the Where clause of the SQL Select statement provided as a
73 dataset property. Each such SQL condition thus acts as an additional filter
74 on the dataset.
75
76 3. The Filtered property inherited from TDataset is no longer used for SQL (server
77 side filters).
78
79 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
80 text matches complete entry.
81
82 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
83 dataset are active (avoids risk of access violation if master is inactive)
84
85 6. TIBEvents: Registered property can now be set at design time even if database not open
86
87 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
88 This should prevent "spillover" of events between sessions.
89
90 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
91 This should ensure that the internal buffer is set up correctly and avoids
92 a duplicate initial row.
93
94 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
95 That is, the DataSize should be the field size * character set width. The
96 value returned by DataSize is now the same as the Dataset buffer size reserved
97 for the field.
98
99 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
100
101 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
102 and vice-versa. This may result in an exception being raised (correctly) for
103 older programs when using dataset fields added to a form and the database has been
104 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
105 In such cases, the field needs to be deleted in the IDE fields editor and then
106 added back in.
107
108 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
109 false if query contains only white space and not just empty.
110
111 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
112 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
113 is cancelled.
114
115 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
116 called on a null field.
117
118 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
119 results in an empty dataTC86 Client side Filtered Dataset 1 X
120 set.
121
122 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
123 a cached update is applied and an exception is raised.
124
125 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
126
127 17. Console Mode Local Database support: backup/restore should now work correctly.
128
129 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
130 possible and an exception raised.
131
132 19. MinimumVersionNo added to Local Database Support. Database will not open if
133 below this version no. and upgrade not possible.
134
135 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
136
137 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
138 not SQL Identifiers are now supported.
139
140 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
141 passed to the Firebird engine for execution.
142
143 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
144 is made to scroll back.
145
146 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
147
148 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
149 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
150
151 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
152 validated. If no match is found in the list of field names and the database has
153 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
154 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
155
156 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
157 with fpc 3.2.
158
159 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
160
161
162 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
163 and is used to override the default settings in the client side "firebird.conf" This
164 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
165 Each line of the string list should be a setting in the same format as "firebird.conf".
166 For example "WireCompression = true" in order to request wire compression on the client side.
167
168 Note: explicit settings in the client side "firebird.conf" appear to take precedence
169 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
170 also require a compatible setting in the server side "firebird.conf". For example
171 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
172 compression to be used.
173
174 Whether or not WireCompression or WireCrypt are in use can be checked using the information
175 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
176 ibx/examples/dbinfo for examples of how to display this information.
177
178 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
179 is a "convenience" property. If set the "WireCompression=true" is added to the
180 ConfigOverrides. If unchecked then this setting is removed.
181
182 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
183 not "INT64".
184
185 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
186 These are:
187 property TimestampFormat: string;
188 property DateFormat: string;
189 property TimeFormat: string;
190
191 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
192 DATETIME and TIME. The format strings use the standard FPC date/time format
193 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
194
195 If any of the above properties are set to an empty string, then the locale default
196 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
197 locale default is extended by appending '.zzz' to include milliseconds.
198
199 TIBCSVDataOut by default sets these properties to the empty string, while the other
200 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
201
202 5. New published property for TIBCSVDataOut:
203 property QuoteStrings: boolean (default true)
204
205 If false then strings are unquoted, otherwise, the QuoteChar property value is
206 used to delimit each and every string in the output.
207
208 6. New published properties for TIBCSVDataOut:
209 property FieldSeparator: string;
210 property HeaderSeparator: string;
211
212 Respectively, these provide the separator character(s) used to separate fields
213 in data and header rows. Both default to ','.
214
215 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
216 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
217 property OnFormatTextString;
218
219 This event handler can be used to process text strings before they are included
220 in the output e.g. to replace unprintable characters with alternative strings.
221 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
222
223 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
224 Uses "FindParam" if in order to find out if a parameter with a given name exists
225 and without raising and exception if it does not.
226
227 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
228 consistency with SQL queries.
229
230 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
231 When true, SQL statement parameter names are parsed case sensitive. Note for
232 TIBDataSet only applies to Select query.
233
234 11. IBEvents: removing a TIBEvent component from a form should no longer result in
235 an IDE exception.
236
237 12. LocalDBSupport: initial database creation should now work correctly
238 when the schema source is an sql file.
239
240 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
241 when defined, this handler will be called by the internal TIBXScript during
242 initial database creation when the schema source is an sql file and may be used
243 to provide a visual indication of progress in console mode.
244
245 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
246 to true while a new local database is being created and its schema populated.
247 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
248 when the database is disconnected/connected during the create DB procedure.
249
250 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
251 are now always ignored and replaced by the user name and password provided as
252 the login parameters for the TIBDatabase referenced from the TIBXScript. The
253 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
254 completely ignored if this property is true.
255
256 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
257 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
258 ImageIndex and SelectImageIndex values on AddNode.
259
260 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
261 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
262 the same database connection.
263
264 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
265 if provided, this should be an conditional SQL expression suitable for
266 including in an SQL Select statement "where" clause. If non-empty and the
267 "Filtered" property is true then the SQL expression provided as the value of
268 the "Filter" property is "ANDed" with any existing condition statement
269 in the SQL statement's "Where" clause.
270
271 If the "Filter" property is set at run time, the "Filtered" property is true
272 and the dataset is already open, then the dataset is closed and re-opened automatically.
273
274 The "Filter" condition may include IBX style parameters. In which case, their
275 value must be set by the dataset's "OnBeforeOpen" event handler.
276
277 This is a public property for TIBDataSet and TIBQuery query and intended for
278 use at run time.
279
280 Note: The property is a published property of TIBTable. The TIBTable functionality
281 is unaffected by this change.
282
283 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
284
285 1. Remove need to check for IsMultiThread by providing access to GUI timers via
286 IBGUIInterface. Note: master/detail delay timer does not apply to console
287 mode apps.
288
289 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
290 statement. This avoids problems if "Execute Block" is used as the Query.
291
292 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
293 internal SQL tokeniser routines.
294
295 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
296 as a select statement, with or without CTEs.
297
298 5. IBSQLParser: parser now recognises the "ROWS" clause.
299
300 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
301 internal SQL tokeniser routines.
302
303 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
304 being raised for valid set statements processed by a data formatter.
305
306 8. New published property for TIBDatabase and TIBXServicesConnection. This is
307 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
308 the path of the Firebird Library used by the database/services connection.
309
310 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
311 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
312 services connection.
313
314 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
315 or param name is not a valid SQL identifier.
316
317 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
318 view of whether the text box should be editable when no DataSource is specified.
319 TIBLookupComboEditBox has been updated to workaround this problem. As long as
320 ReadOnly is false, the text box is editable when no DataSource is specified.
321
322 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
323 the FBLIB environment variable. If you do not want to permit this then you
324 must modify the Register procedure in the design/IBDBReg.pas unit to remove
325 this setting.
326
327 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
328
329 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
330 Utf8EscapeControlChars
331
332 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
333
334 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
335 all previous copies of the IBX source code tree before installing this release.
336
337 The IBX packages used by most users have not changed, with one exception. The
338 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
339 to use the IBServices unit in your applications, please add the iblegacyServices
340 to the list of dependencies. To do this, open the Project Inspector and select
341 Add->New Requirement and select "ibLegacyServices" from the list of available
342 packages.
343
344 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
345 the IBServices unit providing what is intended to be a clearer and easier to
346 use set of IB Services components. See Chapter 10 of the IBX User Guide for
347 more information and the guide to "Firebird Service Management Using IBX".
348 As indicated above, the legacy services components are still available and
349 provided in a separate package. There is no need to update working applications
350 using the older versions except for an additional package dependency.
351
352 2. The IBX packages and source code tree have been re-organised in an attempt to
353 finally get rid of the "duplicate ppu" warnings. This re-organisation should
354 not affect existing users. Section 2.3 of the IBX User Guide describes the
355 new set of IBX packages.
356
357 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
358 updated to use the new Services API components.
359
360 4. The iblocal package has been updated to use the new Services API components.
361
362 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
363 TIBXSecurityService. It had been wrongly classified in the previous version
364 as a per database configuration item. It is global to a server and hence
365 correctly positioned as part of the Security Package. In the DBAdmin example,
366 the setting has moved to the mappings page.
367
368 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
369 are ignored.
370
371 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
372 closed before the database is dropped. Before and After Disconnect event handlers
373 are also fired.
374
375 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
376 is started and not just the first time.
377
378 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
379 depenendency with comp type.
380
381 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
382
383 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
384 then this is recognised and not ignored.
385
386 12. TIBDataSet, TIBQuery, TIBTable: additions:
387 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
388 function GetPerfStatistics(var stats: TPerfCounters): boolean;
389 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
390
391 GetRowsAffected returns the affected row counts from the last insert/update/delete
392 if EnableStatistics = true then GetPerfStatistics returns the current stats
393 counters for the select query. Note: stats accumulate after each fetch from
394 the database. To get total query cost after open, call the "Last" method
395 and then GetPerfStatistics.
396
397 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
398
399 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
400 in parenthesises.
401
402 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
403 SQL identifiers are always delimited by double quotes. If false, then they are
404 only delimited if the identifier is a reserved word, contains lower case or special
405 characters. Set this property to true to retain previous behaviour.
406
407 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
408 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
409
410 16. TIBDataSet, TIBQuery, TIBTable: addition:
411 property MasterDetailDelay: integer {defaults to zero}
412
413 When non-zero and the dataset is a detail table referencing a master table
414 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
415 then a synchronisation delay is added (in milliseconds) between the master
416 row changing and the detail dataset being re-opened. If the master dataset
417 is scrolled before the delay expires then the delay is reset. This can be used
418 to avoid performance overheads when scrolling through a large master dataset.
419
420 Note: uses fptimer and hence requires a thread manager. Under Linux the
421 chreads unit must be included in your project. TTimer is not used in order
422 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
423
424 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
425 with Extract Option eoDatabase.
426
427 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
428 When a deLayoutChanged event is reported on the ListSource dataset, the
429 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
430 relationship with the control's datasource (master).
431
432 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
433
434 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
435 stubs. Pedantic fix really, as procedures output in dependency order anyway.
436
437 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
438 DDL (Firebird 3 and later only).
439
440 22. TIBLookupComboBox Autocomplete Fixes:
441 i. Only appended text is now selected after autocomplete.
442 ii. Uppercase keys no longer ignored for autocomplete.
443 iii. Retain Prefix case is now honoured correctly.
444 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
445 before autocomplete performed. i.e. behaviour now the same as when
446 no DataSource assigned.
447
448 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
449 between SQL statements.
450
451 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
452 ObjectNames are converted to upper case before matching against metadata object
453 names, unless the objectname is delimited by double quotes, in which case, the
454 double quotes are removed and the remaining string is used (unmodified) to match
455 against the metadata object name.
456
457 If true then the ObjectName is used as is without modification and matched
458 against the metadata object name. No attempt is made to remove double quotes.
459
460 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
461 with eoTrigger, these extract types can be used to select only Database Triggers,
462 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
463
464 26. TIBXScript: If an exception occurs during the processing of a statement, the
465 statement separate character is now reset to the default (';').
466
467 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
468
469 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
470 a commit or reconnect statement and instead activated only when next SQL statement
471 is executed.
472
473 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
474
475 30. TIBXScript: case insensitive regex now used when matching statements instead of
476 converting statement to upper case.
477
478 31. TIBExtract: metadata comments now supported. New published property
479 IncludeMetaDataComments (default true). If true then metadata comments included
480 in extracted DDL. New Extract Object member eoComments. This may be used with
481 ExtractObject method to list all metadata comments.
482
483 32. TIBExtract: ListObjectNames method added.
484
485 33. Updated Database component editor to support additional connection string
486 types.
487
488 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
489
490 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
491 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
492 RELEASE.
493
494 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
495
496 1. IBExtract: Identity columns - add additional check for null column for generator name.
497
498 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
499 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
500 information). However, this is also a very useful mechanism for returning updated computed by
501 column values. Values returned as a result of executing an Insert or Update statement
502 replace existing values in the current row for each corresponding column.
503
504 Previously, if a dataset's select query included read only (computed by) fields then
505 an automatic row refresh was performed after an insert or update query had been processed,
506 irrespective of the setting of the "ForcedUpdates" property. This has changed such
507 that an automatic refresh is no longer performed if an insert or update query contains
508 a returning clause that updates one or more fields on the current row. A full row
509 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
510 field values and the select query contains read only fields. Use of Insert/update
511 returning should be significantly more efficient than executing a refresh query.
512
513 This behaviour change is intended to be backwards compatible and there should be no need to change
514 existing programs, other than to improve performance by using the new capability.
515
516 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
517 they are called when the dataset row is being deleted, there is no value in
518 updating the current record from the query result. Instead, a new event handler
519 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
520 an OnDeleteReturning event handler is provided then it is called with the IResults returned
521 by the query. The event handler can then interrogate the query results and
522 perform whatever action is necessary. For example to confirm, to the user,
523 the deletion of a row with the returned values.
524
525 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
526 any Computed By or Identity Columns. The IBTables example has been updated to
527 illustrate the computation of the employee Full Name on update.
528
529 5. TIBTable: The GeneratorField property is now published.
530
531 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
532 When InsertSQL is generated, the Identity columns are not included in the list of values to
533 be inserted. A RETURNING clause is added to the insert statement to return the value of
534 each Identity column after the insert is executed.
535
536 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
537 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
538 Insert..Returning clause.
539
540 8. TIBGenerator: small performance improvement by not preparing query each time
541 a new value is generated.
542
543 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
544
545 10. Property editors will now sync table name to a System Table when "Include System
546 Tables" is selected and the query is for a System Table.
547
548 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
549 values are no longer converted to milliseconds from TDateTime and then back again
550 to TDateTime (the conversion to milliseconds is the default TDataset approach).
551
552 12. Property Editors handling of Stored Procedures.
553 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
554 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
555 query).
556 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
557
558 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
559 can be used to select a package. If non-empty, the stored procedure name is
560 expected to be a stored procedure defined in the specified package and the
561 generated SQL will be as required for a stored procedure located in a package.
562
563 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
564 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
565 which a stored procedure can be selected. With no package name selected, non-package
566 stored procedures are listed.
567
568 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
569 for password on reconnect.
570
571 16. TIBDatabase: use IAttachment for connection default character set id, code page
572 and character set name.
573
574 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
575 DB info lookups"
576
577 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
578
579 19. Add a property Editor for TIBUpdate.RefreshSQL.
580
581 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
582 parameters. This stops an exception being raised when the field cannot be
583 located in the record buffer.
584
585 21. Property Editors now automatically include System Tables when opened and when the query table
586 is a System Table.
587
588 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
589 This avoids errors due to a stale SQRB or SRB being used for the next query.
590
591 23. IBServices: Service attach parameters now include "expected_db". This is used to
592 add the SPB item isc_spb_expected_db. This names a database using
593 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
594 database. examples/services re-written to illustrate use of "expected_db".
595
596 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
597 This avoids truncated backups when the server returns a timeout (busy) response.
598
599 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
600
601 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
602 databasenames. These are respectively expanded to the local system's temp directory
603 (including trailing delimiter) or to a prescribed data directory (including
604 trailing delimiter). Under Unix systems the data directory is a hidden directory
605 in the user's home directory. The hidden directory name is either the string returned
606 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
607 Under Windows, the directory is the same as the Data Directory as decribed
608 above but instead prefixed by the User's application data path. These may be
609 used to improve application portability for Personal Databases.
610
611 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
612 this has not worked for a long time and is not useful either. FieldDefs should be
613 managed using the Fields Editor as with any other dataset. To access the fields
614 editor for a TIBTable component, double click on the component. The fields editor
615 is then displayed.
616
617 28. TIBDatabaseInfo: new properties/function
618 * DateDBCreated (returns date/time database created)
619 * TransactionCount (returns no. of active transactions)
620 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
621 * PagesFree (Firebird 3 or later)
622 * PagesUsed (Firebird 3 or later)
623 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
624 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
625
626 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
627
628 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
629
630 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
631 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
632
633 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
634 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
635 firing during backup and restore.
636
637 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
638 for verbose output using the new property "StatisticsRequested".
639 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
640
641 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
642
643 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
644 palette. This uses the online validation feature added in Firebird 2.5. The
645 services's properties enable inclusion/exclusion of tables and indexes using
646 regular expressions. See.
647 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
648
649 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
650 option on a database.
651
652 37. TIBCustomService: Assign method implemented to allow copying of service login
653 context between service API components. "Detach" method now only detaches
654 service when last reference to the service interface detaches. Tidy up of
655 code for SetActive and Attach methods including password hiding.
656
657 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
658 and used to determine the auth method and protocol used for the connection.
659
660 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
661 a Create Database Statement generated by IBX.
662
663 40. All IBServices now have an additional published property "PortNo". This may
664 be set to a non-standard port number when necessary. If zero then the default
665 port number is used.
666
667 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
668 and not just the mouse.
669
670 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
671
672 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
673 image index and selected image index for each node to be set from a database field.
674
675 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
676 then database schema includes grants to all users. If not present then the
677 only user grants included are those to User PUBLIC.
678
679 45. TIBTreeView: performance improvement. When expanding include both expanded node
680 and child nodes in dataset.
681
682
683 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
684
685 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
686 changes.
687
688 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
689 Bug could result in truncated multi-byte character set values.
690
691 3. Changes consequential on moving fbintf character set utility functions from
692 IFirebirdAPI to IAttachment.
693
694 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
695
696 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
697 results in autocomplete ignoring prefix text.
698
699 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
700 entering a new name into the text box.
701
702 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
703 Firebird rather than recomputing it.
704
705 8. Property Editor positioning tidy up: All IBX Property editors should now be
706 screen centre. Previously some were "poDesigned" which may be inappropriate
707 for multi monitor desktops.
708
709 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
710
711 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
712 a transaction and always reset the object.
713
714 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
715
716 13. TIBXScript: Allow for override of database filename in Create Database statements.
717
718 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
719 to a gbak format archive.
720
721 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
722
723 16. IBLocaldb: Drop database if error creating an empty database.
724
725 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
726 unless selected node not in current dataset.
727
728 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
729 to TIBCustomService, and IBlocalDB code tidy up.
730
731 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
732 behaviour due to uninitialised variable.
733
734 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
735 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
736
737 21. IBSQL: When Database changed ensure that all resources are freed.
738
739 22. IBCustomDataset: When database changed ensure that queries an unprepared.
740
741 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
742 * Line Wrap on SQL Token boundaries (on user command)
743 * auto-complete table names in drop down list of table names
744 * Double click on tablename or field name adds to SQL text
745
746 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
747
748 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
749 TVariantArray. Seems to avoid memory corruption in Windows (probably a
750 workaround for a problem in fpc 3.0.4 win64).
751
752 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
753
754 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
755
756 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
757
758 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
759 include remote system name.
760
761 2. TIBExtract: No longer include comment header and COMMIT statement for empty
762 tables when data included in output.
763
764 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
765 and timing information to be written to stdout. This may be used to locate
766 performance bottlenecks.
767
768 4. SQLParser: only call "OnChanging" event handler when value is different.
769
770 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
771
772 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
773 that BindFields is called when the query is next activated. Avoids FieldName
774 not found error.
775
776 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
777 purpose and allows the programmer to define any action they want for Update, Insert
778 or Delete. This may be complex SQL (similar to a Trigger), application specific
779 filtering of updates, or use of statements such as Grant or Revoke instead of
780 normal DML. See User Manual for more information.
781
782 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
783
784 1. TIBEvents: Fix uninitialised variable that could result in lost events.
785
786 2. TIBExtract: Added support for FB3 "USAGE" privilege.
787
788 3. TIBExtract: data formatted as Charset set "octets" is now output using
789 hexadecimal notation.
790
791 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
792 using a simple XML format.
793
794 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
795 grants to these objects.
796
797 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
798 dependency problems restoring complex databases.
799
800 7. TIBXScript: This component has been restructured to allow for the processing of
801 embedded XML in INSERT statements and to support interactive sources in addition
802 to non-interactive data sources such as files.
803
804 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
805
806 9. TIBXScript: ISQL compatiable Set statements are now supported:
807 SET SQL DIALECT
808 SET TERM
809 SET AUTODDL
810 SET BAIL
811 SET ECHO
812 SET COUNT
813 SET STATS
814 SET NAMES <character set>
815
816 10. IBVersion unit added to hold current IBX Version Number information.
817
818 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
819 and domain definitions.
820
821 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
822 fully supported.
823
824 13. TIBExtract: when a database dump includes data, the generator values are now also set.
825
826 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
827
828 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
829
830 See also doc/IBX4LazarusGuide.pdf for important information on
831 upgrading to IBX2.
832
833 1. Size property of TIBStringField is now the width in characters of the field
834 and not the byte length. This applies only to multi-byte character sets such
835 as UTF8. The original approach aligned with TStringField. However, the TStringField
836 code is not recognised as a bug and hence this change to align the behaviour.
837 The TStringField change is expected in fpc 3.2.0.
838
839 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
840 true (default) then Size property value saved in the lfm is ignored. Size is
841 always set from the dynamic information read from the database. It is unclear
842 why anyone would want to override this and set Size to false.
843
844 3. ibxscript: should now handle correctly a Case..End statement within a procedure
845 block.
846
847 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
848 exist when an attempt is made to connect to it (run time only) then an attempt
849 is made to create the database.
850
851 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
852 has been successfully created as a result of a call to CreateDatabase or when
853 creating a database after it was found not to exist.
854
855 6. DBControlGrid: a race condition could result in the wrong row image being
856 written to the cache. This has been avoided by a trip round the message
857 loop before rendering the row image.
858
859 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
860 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
861 known to risk corrupt rendering of row images when the control is first
862 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
863 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
864
865 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
866 a TDateEdit control located on an editor panel.
867
868 9. TIBExtract: brought up-to-date plus many bug fixes.
869
870 10. DBControlGrid: Removed memory leak when updating rows.
871
872 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
873
874 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
875
876 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
877 when target codepage is CP_NONE. This is a workaround for
878 http://bugs.freepascal.org/view.php?id=30622.
879
880 2. DBLog option removed from TIBStatisticalService - not supported by server
881 since Firebird 1.5.
882
883 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
884 similar.
885
886 4. IBCodePage: updated mapping between codepages and character id.
887
888 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
889 Firebird. Character sets with a char width of two are not UTF16.
890
891 6. Strings received from the database are now always transliterated into UTF8
892 regardless of the database character set or connection character set. This
893 is for compatibility with the LCL.
894
895 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
896
897 1. IBBlob: Defer reading of blob until read method called. This avoids having to
898 read in an entire blob just to get the size of the blob. General performance
899 improvement when opening datasets containing blobs.
900
901 2. Clearing a Blob now sets the corresponding field's modified flag.
902
903 3. IBLookupCombo: When not performing auto-complete, original query sort order
904 is now used.
905
906 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
907 determined.
908
909 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
910
911 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
912 lazarus 1.6.0
913
914 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
915 compilation error.
916
917 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
918
919 1. No character set specified for connection: when a text blob is retrieved, the
920 character set is determined by looking up the native character set using then
921 Firebird API. Otherwise a text mode blob is assumed to have the same character
922 set as the connection.
923
924 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
925 for Login Dialog returing a change to the database path.
926
927 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
928 to be changed from that given in the TIBDatabase/TIBServer component and for the
929 entered value to be saved on a project specific basis (design time only).
930
931 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
932 column fieldname. If they are the same then it is acts as a look up for the KeyValue
933 Otherwise, it sets the column text to the selected ListField Value.
934
935 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
936 column width.
937
938 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
939 and a case insensitive search is requested.
940
941 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
942 or column ListSource.
943
944 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
945 unprepare) when closing and the text has not changed.
946
947 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
948 Less likely to cause a cursor re-use error on Windows.

950 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
951 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
952
953 11. TIBTreeView: Guard against nil destination on record changed
954
955 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
956 string type with the code page set to reflect the returned field encoding after
957 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
958 earlier versions.
959
960 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
961 will now result in transliteration to the code page specified for the Firebird driver
962 if the assigned string has a different code page. FPC 3.0.0 onwards only.
963
964 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
965 is ignored and the lc_ctype value, when the database is opened, is set to align with
966 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
967 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
968 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
969 the GETACP is used to determine the Windows code page.
970
971 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
972 name used as the lc_ctype when the database was opened. Only valid while the
973 Database is connected.
974
975 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
976 id that corresponds to the DefaultCharSetName.
977
978 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
979
980 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
981 path is given and database attach fails due to access permission issues on the
982 temp directory or security database, then the attach is retried with "localhost:"
983 prefixing the databasename. This should avoid problems when the database has to
984 be accessed by a local (e.g. classic) server and libfbembed is used.
985
986 2. Windows: revised search order for Firebird DLL:
987 i. The Firebird Embedded Server in the application Directory.
988 ii. If the FIREBIRD environment variable is set then the directory this
989 points to is searched for the FB Client DLL and then then underlying
990 "bin" directory.
991 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
992 is used to locate the Firebird installation directory and the underlying
993 "bin" directory is searched for the FB Client DLL.
994 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
995 are searched for the FB Client DLL.
996 v. The PATH Environment variable is used to search for the FB Client DLL.
997 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
998
999 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1000 See doc/readme.scriptengine and example applications.
1001
1002 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1003 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1004 See dpc/readme.localdatabase and example applications.
1005
1006 5. IBDynamicGrid: Reordering on column header click should now also work for
1007 dynamic columns.
1008
1009 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1010 between incrementing/decrementing the lock count and signalling the event.
1011
1012 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1013
1014 1.3.2 was never formally released and only made available as beta copies.
1015
1016 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1017
1018 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1019
1020 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1021
1022 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1023 i.e. when it is a calculated field
1024
1025 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1026 This problem was due to a race condition between recalculating row heights and
1027 determining which row was selected by the mouse click. The row height calculation
1028 is now deferred by an extra trip round the message loop allowing the row to
1029 be always calculated on the current grid layout rather than risking it being
1030 calculated on the grid layout after the expanded row has been shrunk.
1031
1032 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1033 Windows.
1034
1035 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1036 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1037 to be determined at runtime. See doc/readme.charactersets.html.
1038
1039 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1040 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1041
1042 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1043 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1044 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1045
1046 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1047 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1048 implies no truncation.
1049
1050 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1051
1052 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1053 (avoids "Not in Edit Mode" error).
1054
1055 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1056
1057 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1058 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1059
1060 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1061
1062 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1063
1064 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1065
1066 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1067
1068 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1069
1070 1. OnCloseUp Event Handler added to TDBLookupProperties
1071
1072 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1073 problem with row size when exception is called.
1074
1075 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1076
1077 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1078 in a TCustomComboBox and ignores return key if in a TCustomMemo
1079
1080 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1081 keyed in i.e. when autocomplete not performed
1082
1083 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1084 console mode applications with all LCL required functions (builtin dialogs and
1085 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1086 not included in your project, IBX should compile and link with a console mode program.
1087 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1088 console mode application or the IDE will automatically assume that your
1089 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1090
1091 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1092 to use the built in dialogs and cursor management. IBDialogs is
1093 included by default if "ibexpress" is in your project source's "uses" clause.
1094 This should be the case for all projects created through the IDE. This is why
1095 you do not want to add the ibexpress package to console mode applications. The
1096 ibexpressconsolemode package has been created to allow console mode programs
1097 to avoid adding LCL dependencies when using IBX, while still having the
1098 unit search paths set up correctly.
1099
1100 Existing users should check to ensure that the "ibexpress" unit is included in
1101 each project's source file (*.lpr).
1102
1103 You may find that in order for the IDE to recognise that ibexpressconsolemode
1104 exists, you have to first open the package in the IDE and then close it. This
1105 adds it to the most recently accessed packages list. To make it permanently
1106 available, add the package name to lazarus' staticpackages.inc file.
1107
1108 Thanks to Julio Jiménez for suggesting support of console mode.
1109
1110 7. SQL Parser can now accept quoted strings that include new lines
1111
1112 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1113 of text on start of edit. This is particularly useful when tabbing to a
1114 column and then inserting text.
1115
1116 9. New Examples provided for IB Services and ISQLMonitor.
1117
1118 10. Fix error when writing to blob streams that recorded only the last buffer
1119 write in the blob stream. In most cases, this did not cause a problem as the
1120 IB Blob Stream is written in a single write. However, with the TDBImage, write
1121 of a graphic type prefix was lost which caused a problem when the image could
1122 not be automatically recognised.
1123
1124 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1125 already open" errors due to random numbers used for the cursor name being identical.
1126
1127 12. IBTable: corrected error that could result in an "Index out of bounds" error
1128 when opening the table and the Primary Key is the last or only column in the
1129 table. Thanks to Rick Hoover for the fix.
1130
1131 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1132 of "UTF-8", and update list of available database character sets. Existing
1133 users should check the current lc_ctype setting in their applications.
1134
1135 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1136
1137 1. Firebird Services: avoid List Index error when opening a service with an
1138 empty Params property.
1139
1140 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1141 Link now set up in Loaded method - avoids occasional failure to apply
1142 SQL markup on initial open.
1143
1144 3. "Employees" example performance improvements when scrolling.
1145
1146 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1147 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1148 random image cached).
1149
1150 5. DBControlGrid: Should now react to changes in panel height at run time.
1151
1152 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1153 even when further rows exist.
1154
1155 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1156 always be derived from panel height and setting this property can cause confusion.
1157 Note for existing projects: to avoid a missing property error at run time,
1158 each form using the DBControlGrid must be opened, updated and saved in the IDE
1159 in order to remove the property value from the lfm.
1160
1161
1162 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1163
1164 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1165 call Prepare before setting parameter values.
1166
1167 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1168
1169 3. Code tidyup and more robust handling of dsql information result vector.
1170
1171 4. Support for centralised handling of transaction status changes. TIBTransaction
1172 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1173 and "AfterExecQuery". The first three are called after the same event is called
1174 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1175 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1176 enable monitoring of transaction status changes for a given transaction to be
1177 handled in a single place. For example, when a change to the dataset occurs
1178 an indicator can be set that shows the user that in order to save changes,
1179 the transaction should be committed. Rather than doing this per dataset, this
1180 can now be done per transaction.
1181
1182 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1183 the dataset is scrolled. However, any changes to the current row are, by default,
1184 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1185 have a new property "DataSetCloseAction" that adds automatic posting of changes
1186 on dataset close. If this property is set to dcDiscardChanges (default) then the
1187 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1188 then IBX will attempt to post any unsaved changes before the dataset is closed
1189 (and after the BeforeClose event handler is called). The exception is when the
1190 dataset is being closed as a result of a transaction rollback. In this case,
1191 no action is taken and any unsaved changes are discarded. This avoids both
1192 unnecessary overhead and the risk that a validation error may occur in the Post
1193 raising an exception and thereby preventing a rollback.
1194
1195 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1196 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1197 width. Display Widths are now corrected by dividing by the max byte width per character.
1198 For UTF8 character sets, the byte width is four and hence the Display Width will be
1199 the byte width divided by 4. The byte width of each character set is determined
1200 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1201 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1202
1203 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1204
1205 8. IBLookupComboEditBox: List should now always be restored to full list when the
1206 control loses focus. Default Key press default interval reduced to 200ms.
1207
1208 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1209 when dataset rows are less than visible rows.
1210
1211 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1212 does not exist or DataSet is empty. More responsive on dataset open. New event
1213 OnRestorePosition. Column sort disabled if no header row.
1214
1215 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1216 while dataset state is dsInsert. Avoids posting errors.
1217
1218 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1219 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1220
1221 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1222
1223 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1224 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1225 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1226 always "posts" the current record regardless or whether or not it may be more appropriate
1227 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1228 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1229 as the first action of the "Post" method and allows the handler to convert the Post
1230 into a Cancel if that is the appropriate action on moving to a different row. This is
1231 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1232 raised here, but it may still be more appropriate to validate a post and signal
1233 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1234
1235 15. On Unix derived systems, the Firebird library name can now be given as a colon
1236 separated list. Each library name on the list is tried in turn, in left to right
1237 order with the first found being used as the firebird library. By default, on Linux,
1238 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1239 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1240
1241 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1242 then it will still attempt to access the database via the Firebird Server and will
1243 require a username and password. If only the pathname is given, then the username
1244 and password should be omitted and the unix file permissions are used to grant
1245 access.
1246
1247 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1248
1249 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1250 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1251 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1252 corresponds to a row of the linked DataSource. Any data aware control on the
1253 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1254
1255 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1256 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1257 takes place during database access. This may be useful when there are performance issues with
1258 the change of cursor. Setting the property to false suppresses the change of cursor.
1259
1260 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1261 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1262 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1263 making all changes permanent immediately rather than when the transaction is explicitly
1264 committed.
1265
1266 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1267 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1268
1269 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1270
1271 Development version only.
1272
1273 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1274
1275 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1276 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1277 "Where" and "Having" clauses to implement user specified filters of arbitrary
1278 complexity.
1279
1280 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1281 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1282 These are:
1283
1284 - TIBLookupComboEditBox
1285 - TIBDynamicGrid
1286 - TIBTreeview
1287
1288 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1289 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1290 to revise the available list and restrict it to items that are prefixed by the
1291 typed text (either case sensitive or case insensitive). Autoinsert allows a
1292 newly typed entry to be added to the list dataset and included in the available
1293 list items.
1294
1295 TIBDynamicGrid is a TDBGrid descendent that provides for:
1296 - automatic resizing of selected columns to fill the available row length
1297 - automatic positioning and sizing of a "totals" control, typically at the
1298 column footer, on a per column basis.
1299 - DataSet resorting on header row click, sorting the dataset by the selected column.
1300 A second click on the same header cell reversed the sort order.
1301 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1302 is automatically expanded and a panel superimposed on it. The panel can have any
1303 number of child controls, typically data aware controls with the same datasource
1304 as the grid allowing for editing of additional fields and more complex editors.
1305 - Reselection of the same row following resorting.
1306 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1307 Its properties are specified on a per column basis and allows for one or more
1308 columns to have their values selected from a list provided by a dataset.
1309 Autocomplete and autoinsert are also available. The existing picklist editor
1310 is unaffected by the extension.
1311
1312 TIBTreeView is a data aware TCustomTreeView.
1313
1314 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1315 zero scale will no longer return an error. An Int64 will be returned instead.
1316
1317 4. TIBTransaction now has events for Before and After Transaction End and a new function
1318 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1319
1320 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1321 repeated multiple times.
1322
1323 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1324 check used to get in the way of using Stored Procedures, and "Update or Insert"
1325 statements.
1326
1327 7. Insert, Modify and Delete property Editors now support Query Generation from
1328 Stored Procedures.
1329
1330 8. Three new examples illustrate the use of the new IB Controls
1331
1332
1333 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1334
1335 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1336 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1337 Gabor Boros for reporting this problem and for testing the improvements).
1338
1339 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1340 See readme.field+param.names in the doc folder.
1341
1342 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1343 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1344
1345 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1346
1347 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1348 actions.
1349
1350 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1351 thanks to Yuriy Kopnin for pointing this out).
1352
1353 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1354
1355 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1356 for both fields and parameter setting.
1357
1358 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1359 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1360
1361 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1362 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1363
1364 11. TIBTable now has a property editor for "MasterFields"
1365
1366 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the

1379 1. In a TIBCustomDataset descendent, a generator now only sets the value when

1384 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library

1403
1404 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1405 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1406
1407 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1408 package is changed to do this (which it should do).
