1 IBX Change Log version (2.4-0 Build 12517) Fri, 19 Feb 2021 13:27:20 +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 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
63 unnecessary CR at end of line on Unix platforms.
64
65 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
66 seconds in order to reduce risk of message loss.
67
68 23. ISQLMonitor: read and write count statistics now available via:
69 property TIBSQLMonitor.ReadCount;
70 IIBSQLMonitorHook.GetWriteCount: integer;
71
72 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
73
74 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
75
76 1. TIBStringField: when a string value is read from a dataset buffer, if the
77 number of UTF8 characters exceeds the string size then string is truncated
78 to the maximum string size. This is usually a problem with fixed width columns
79 right padded with white space.
80
81 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
82 If SQLFiltered is set then when a dataset is opened, each line in the
83 SQLFilterParams property is assumed to be a SQL condition clause and
84 ANDed into the Where clause of the SQL Select statement provided as a
85 dataset property. Each such SQL condition thus acts as an additional filter
86 on the dataset.
87
88 3. The Filtered property inherited from TDataset is no longer used for SQL (server
89 side filters).
90
91 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
92 text matches complete entry.
93
94 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
95 dataset are active (avoids risk of access violation if master is inactive)
96
97 6. TIBEvents: Registered property can now be set at design time even if database not open
98
99 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
100 This should prevent "spillover" of events between sessions.
101
102 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
103 This should ensure that the internal buffer is set up correctly and avoids
104 a duplicate initial row.
105
106 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
107 That is, the DataSize should be the field size * character set width. The
108 value returned by DataSize is now the same as the Dataset buffer size reserved
109 for the field.
110
111 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
112
113 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
114 and vice-versa. This may result in an exception being raised (correctly) for
115 older programs when using dataset fields added to a form and the database has been
116 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
117 In such cases, the field needs to be deleted in the IDE fields editor and then
118 added back in.
119
120 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
121 false if query contains only white space and not just empty.
122
123 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
124 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
125 is cancelled.
126
127 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
128 called on a null field.
129
130 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
131 results in an empty dataTC86 Client side Filtered Dataset 1 X
132 set.
133
134 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
135 a cached update is applied and an exception is raised.
136
137 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
138
139 17. Console Mode Local Database support: backup/restore should now work correctly.
140
141 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
142 possible and an exception raised.
143
144 19. MinimumVersionNo added to Local Database Support. Database will not open if
145 below this version no. and upgrade not possible.
146
147 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
148
149 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
150 not SQL Identifiers are now supported.
151
152 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
153 passed to the Firebird engine for execution.
154
155 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
156 is made to scroll back.
157
158 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
159
160 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
161 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
162
163 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
164 validated. If no match is found in the list of field names and the database has
165 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
166 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
167
168 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
169 with fpc 3.2.
170
171 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
172
173
174 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
175 and is used to override the default settings in the client side "firebird.conf" This
176 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
177 Each line of the string list should be a setting in the same format as "firebird.conf".
178 For example "WireCompression = true" in order to request wire compression on the client side.
179
180 Note: explicit settings in the client side "firebird.conf" appear to take precedence
181 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
182 also require a compatible setting in the server side "firebird.conf". For example
183 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
184 compression to be used.
185
186 Whether or not WireCompression or WireCrypt are in use can be checked using the information
187 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
188 ibx/examples/dbinfo for examples of how to display this information.
189
190 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
191 is a "convenience" property. If set the "WireCompression=true" is added to the
192 ConfigOverrides. If unchecked then this setting is removed.
193
194 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
195 not "INT64".
196
197 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
198 These are:
199 property TimestampFormat: string;
200 property DateFormat: string;
201 property TimeFormat: string;
202
203 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
204 DATETIME and TIME. The format strings use the standard FPC date/time format
205 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
206
207 If any of the above properties are set to an empty string, then the locale default
208 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
209 locale default is extended by appending '.zzz' to include milliseconds.
210
211 TIBCSVDataOut by default sets these properties to the empty string, while the other
212 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
213
214 5. New published property for TIBCSVDataOut:
215 property QuoteStrings: boolean (default true)
216
217 If false then strings are unquoted, otherwise, the QuoteChar property value is
218 used to delimit each and every string in the output.
219
220 6. New published properties for TIBCSVDataOut:
221 property FieldSeparator: string;
222 property HeaderSeparator: string;
223
224 Respectively, these provide the separator character(s) used to separate fields
225 in data and header rows. Both default to ','.
226
227 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
228 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
229 property OnFormatTextString;
230
231 This event handler can be used to process text strings before they are included
232 in the output e.g. to replace unprintable characters with alternative strings.
233 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
234
235 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
236 Uses "FindParam" if in order to find out if a parameter with a given name exists
237 and without raising and exception if it does not.
238
239 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
240 consistency with SQL queries.
241
242 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
243 When true, SQL statement parameter names are parsed case sensitive. Note for
244 TIBDataSet only applies to Select query.
245
246 11. IBEvents: removing a TIBEvent component from a form should no longer result in
247 an IDE exception.
248
249 12. LocalDBSupport: initial database creation should now work correctly
250 when the schema source is an sql file.
251
252 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
253 when defined, this handler will be called by the internal TIBXScript during
254 initial database creation when the schema source is an sql file and may be used
255 to provide a visual indication of progress in console mode.
256
257 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
258 to true while a new local database is being created and its schema populated.
259 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
260 when the database is disconnected/connected during the create DB procedure.
261
262 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
263 are now always ignored and replaced by the user name and password provided as
264 the login parameters for the TIBDatabase referenced from the TIBXScript. The
265 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
266 completely ignored if this property is true.
267
268 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
269 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
270 ImageIndex and SelectImageIndex values on AddNode.
271
272 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
273 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
274 the same database connection.
275
276 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
277 if provided, this should be an conditional SQL expression suitable for
278 including in an SQL Select statement "where" clause. If non-empty and the
279 "Filtered" property is true then the SQL expression provided as the value of
280 the "Filter" property is "ANDed" with any existing condition statement
281 in the SQL statement's "Where" clause.
282
283 If the "Filter" property is set at run time, the "Filtered" property is true
284 and the dataset is already open, then the dataset is closed and re-opened automatically.
285
286 The "Filter" condition may include IBX style parameters. In which case, their
287 value must be set by the dataset's "OnBeforeOpen" event handler.
288
289 This is a public property for TIBDataSet and TIBQuery query and intended for
290 use at run time.
291
292 Note: The property is a published property of TIBTable. The TIBTable functionality
293 is unaffected by this change.
294
295 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
296
297 1. Remove need to check for IsMultiThread by providing access to GUI timers via
298 IBGUIInterface. Note: master/detail delay timer does not apply to console
299 mode apps.
300
301 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
302 statement. This avoids problems if "Execute Block" is used as the Query.
303
304 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
305 internal SQL tokeniser routines.
306
307 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
308 as a select statement, with or without CTEs.
309
310 5. IBSQLParser: parser now recognises the "ROWS" clause.
311
312 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
313 internal SQL tokeniser routines.
314
315 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
316 being raised for valid set statements processed by a data formatter.
317
318 8. New published property for TIBDatabase and TIBXServicesConnection. This is
319 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
320 the path of the Firebird Library used by the database/services connection.
321
322 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
323 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
324 services connection.
325
326 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
327 or param name is not a valid SQL identifier.
328
329 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
330 view of whether the text box should be editable when no DataSource is specified.
331 TIBLookupComboEditBox has been updated to workaround this problem. As long as
332 ReadOnly is false, the text box is editable when no DataSource is specified.
333
334 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
335 the FBLIB environment variable. If you do not want to permit this then you
336 must modify the Register procedure in the design/IBDBReg.pas unit to remove
337 this setting.
338
339 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
340
341 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
342 Utf8EscapeControlChars
343
344 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
345
346 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
347 all previous copies of the IBX source code tree before installing this release.
348
349 The IBX packages used by most users have not changed, with one exception. The
350 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
351 to use the IBServices unit in your applications, please add the iblegacyServices
352 to the list of dependencies. To do this, open the Project Inspector and select
353 Add->New Requirement and select "ibLegacyServices" from the list of available
354 packages.
355
356 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
357 the IBServices unit providing what is intended to be a clearer and easier to
358 use set of IB Services components. See Chapter 10 of the IBX User Guide for
359 more information and the guide to "Firebird Service Management Using IBX".
360 As indicated above, the legacy services components are still available and
361 provided in a separate package. There is no need to update working applications
362 using the older versions except for an additional package dependency.
363
364 2. The IBX packages and source code tree have been re-organised in an attempt to
365 finally get rid of the "duplicate ppu" warnings. This re-organisation should
366 not affect existing users. Section 2.3 of the IBX User Guide describes the
367 new set of IBX packages.
368
369 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
370 updated to use the new Services API components.
371
372 4. The iblocal package has been updated to use the new Services API components.
373
374 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
375 TIBXSecurityService. It had been wrongly classified in the previous version
376 as a per database configuration item. It is global to a server and hence
377 correctly positioned as part of the Security Package. In the DBAdmin example,
378 the setting has moved to the mappings page.
379
380 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
381 are ignored.
382
383 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
384 closed before the database is dropped. Before and After Disconnect event handlers
385 are also fired.
386
387 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
388 is started and not just the first time.
389
390 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
391 depenendency with comp type.
392
393 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
394
395 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
396 then this is recognised and not ignored.
397
398 12. TIBDataSet, TIBQuery, TIBTable: additions:
399 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
400 function GetPerfStatistics(var stats: TPerfCounters): boolean;
401 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
402
403 GetRowsAffected returns the affected row counts from the last insert/update/delete
404 if EnableStatistics = true then GetPerfStatistics returns the current stats
405 counters for the select query. Note: stats accumulate after each fetch from
406 the database. To get total query cost after open, call the "Last" method
407 and then GetPerfStatistics.
408
409 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
410
411 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
412 in parenthesises.
413
414 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
415 SQL identifiers are always delimited by double quotes. If false, then they are
416 only delimited if the identifier is a reserved word, contains lower case or special
417 characters. Set this property to true to retain previous behaviour.
418
419 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
420 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
421
422 16. TIBDataSet, TIBQuery, TIBTable: addition:
423 property MasterDetailDelay: integer {defaults to zero}
424
425 When non-zero and the dataset is a detail table referencing a master table
426 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
427 then a synchronisation delay is added (in milliseconds) between the master
428 row changing and the detail dataset being re-opened. If the master dataset
429 is scrolled before the delay expires then the delay is reset. This can be used
430 to avoid performance overheads when scrolling through a large master dataset.
431
432 Note: uses fptimer and hence requires a thread manager. Under Linux the
433 chreads unit must be included in your project. TTimer is not used in order
434 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
435
436 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
437 with Extract Option eoDatabase.
438
439 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
440 When a deLayoutChanged event is reported on the ListSource dataset, the
441 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
442 relationship with the control's datasource (master).
443
444 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
445
446 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
447 stubs. Pedantic fix really, as procedures output in dependency order anyway.
448
449 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
450 DDL (Firebird 3 and later only).
451
452 22. TIBLookupComboBox Autocomplete Fixes:
453 i. Only appended text is now selected after autocomplete.
454 ii. Uppercase keys no longer ignored for autocomplete.
455 iii. Retain Prefix case is now honoured correctly.
456 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
457 before autocomplete performed. i.e. behaviour now the same as when
458 no DataSource assigned.
459
460 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
461 between SQL statements.
462
463 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
464 ObjectNames are converted to upper case before matching against metadata object
465 names, unless the objectname is delimited by double quotes, in which case, the
466 double quotes are removed and the remaining string is used (unmodified) to match
467 against the metadata object name.
468
469 If true then the ObjectName is used as is without modification and matched
470 against the metadata object name. No attempt is made to remove double quotes.
471
472 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
473 with eoTrigger, these extract types can be used to select only Database Triggers,
474 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
475
476 26. TIBXScript: If an exception occurs during the processing of a statement, the
477 statement separate character is now reset to the default (';').
478
479 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
480
481 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
482 a commit or reconnect statement and instead activated only when next SQL statement
483 is executed.
484
485 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
486
487 30. TIBXScript: case insensitive regex now used when matching statements instead of
488 converting statement to upper case.
489
490 31. TIBExtract: metadata comments now supported. New published property
491 IncludeMetaDataComments (default true). If true then metadata comments included
492 in extracted DDL. New Extract Object member eoComments. This may be used with
493 ExtractObject method to list all metadata comments.
494
495 32. TIBExtract: ListObjectNames method added.
496
497 33. Updated Database component editor to support additional connection string
498 types.
499
500 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
501
502 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
503 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
504 RELEASE.
505
506 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
507
508 1. IBExtract: Identity columns - add additional check for null column for generator name.
509
510 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
511 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
512 information). However, this is also a very useful mechanism for returning updated computed by
513 column values. Values returned as a result of executing an Insert or Update statement
514 replace existing values in the current row for each corresponding column.
515
516 Previously, if a dataset's select query included read only (computed by) fields then
517 an automatic row refresh was performed after an insert or update query had been processed,
518 irrespective of the setting of the "ForcedUpdates" property. This has changed such
519 that an automatic refresh is no longer performed if an insert or update query contains
520 a returning clause that updates one or more fields on the current row. A full row
521 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
522 field values and the select query contains read only fields. Use of Insert/update
523 returning should be significantly more efficient than executing a refresh query.
524
525 This behaviour change is intended to be backwards compatible and there should be no need to change
526 existing programs, other than to improve performance by using the new capability.
527
528 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
529 they are called when the dataset row is being deleted, there is no value in
530 updating the current record from the query result. Instead, a new event handler
531 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
532 an OnDeleteReturning event handler is provided then it is called with the IResults returned
533 by the query. The event handler can then interrogate the query results and
534 perform whatever action is necessary. For example to confirm, to the user,
535 the deletion of a row with the returned values.
536
537 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
538 any Computed By or Identity Columns. The IBTables example has been updated to
539 illustrate the computation of the employee Full Name on update.
540
541 5. TIBTable: The GeneratorField property is now published.
542
543 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
544 When InsertSQL is generated, the Identity columns are not included in the list of values to
545 be inserted. A RETURNING clause is added to the insert statement to return the value of
546 each Identity column after the insert is executed.
547
548 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
549 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
550 Insert..Returning clause.
551
552 8. TIBGenerator: small performance improvement by not preparing query each time
553 a new value is generated.
554
555 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
556
557 10. Property editors will now sync table name to a System Table when "Include System
558 Tables" is selected and the query is for a System Table.
559
560 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
561 values are no longer converted to milliseconds from TDateTime and then back again
562 to TDateTime (the conversion to milliseconds is the default TDataset approach).
563
564 12. Property Editors handling of Stored Procedures.
565 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
566 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
567 query).
568 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
569
570 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
571 can be used to select a package. If non-empty, the stored procedure name is
572 expected to be a stored procedure defined in the specified package and the
573 generated SQL will be as required for a stored procedure located in a package.
574
575 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
576 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
577 which a stored procedure can be selected. With no package name selected, non-package
578 stored procedures are listed.
579
580 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
581 for password on reconnect.
582
583 16. TIBDatabase: use IAttachment for connection default character set id, code page
584 and character set name.
585
586 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
587 DB info lookups"
588
589 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
590
591 19. Add a property Editor for TIBUpdate.RefreshSQL.
592
593 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
594 parameters. This stops an exception being raised when the field cannot be
595 located in the record buffer.
596
597 21. Property Editors now automatically include System Tables when opened and when the query table
598 is a System Table.
599
600 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
601 This avoids errors due to a stale SQRB or SRB being used for the next query.
602
603 23. IBServices: Service attach parameters now include "expected_db". This is used to
604 add the SPB item isc_spb_expected_db. This names a database using
605 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
606 database. examples/services re-written to illustrate use of "expected_db".
607
608 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
609 This avoids truncated backups when the server returns a timeout (busy) response.
610
611 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
612
613 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
614 databasenames. These are respectively expanded to the local system's temp directory
615 (including trailing delimiter) or to a prescribed data directory (including
616 trailing delimiter). Under Unix systems the data directory is a hidden directory
617 in the user's home directory. The hidden directory name is either the string returned
618 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
619 Under Windows, the directory is the same as the Data Directory as decribed
620 above but instead prefixed by the User's application data path. These may be
621 used to improve application portability for Personal Databases.
622
623 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
624 this has not worked for a long time and is not useful either. FieldDefs should be
625 managed using the Fields Editor as with any other dataset. To access the fields
626 editor for a TIBTable component, double click on the component. The fields editor
627 is then displayed.
628
629 28. TIBDatabaseInfo: new properties/function
630 * DateDBCreated (returns date/time database created)
631 * TransactionCount (returns no. of active transactions)
632 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
633 * PagesFree (Firebird 3 or later)
634 * PagesUsed (Firebird 3 or later)
635 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
636 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
637
638 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
639
640 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
641
642 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
643 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
644
645 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
646 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
647 firing during backup and restore.
648
649 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
650 for verbose output using the new property "StatisticsRequested".
651 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
652
653 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
654
655 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
656 palette. This uses the online validation feature added in Firebird 2.5. The
657 services's properties enable inclusion/exclusion of tables and indexes using
658 regular expressions. See.
659 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
660
661 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
662 option on a database.
663
664 37. TIBCustomService: Assign method implemented to allow copying of service login
665 context between service API components. "Detach" method now only detaches
666 service when last reference to the service interface detaches. Tidy up of
667 code for SetActive and Attach methods including password hiding.
668
669 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
670 and used to determine the auth method and protocol used for the connection.
671
672 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
673 a Create Database Statement generated by IBX.
674
675 40. All IBServices now have an additional published property "PortNo". This may
676 be set to a non-standard port number when necessary. If zero then the default
677 port number is used.
678
679 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
680 and not just the mouse.
681
682 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
683
684 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
685 image index and selected image index for each node to be set from a database field.
686
687 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
688 then database schema includes grants to all users. If not present then the
689 only user grants included are those to User PUBLIC.
690
691 45. TIBTreeView: performance improvement. When expanding include both expanded node
692 and child nodes in dataset.
693
694
695 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
696
697 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
698 changes.
699
700 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
701 Bug could result in truncated multi-byte character set values.
702
703 3. Changes consequential on moving fbintf character set utility functions from
704 IFirebirdAPI to IAttachment.
705
706 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
707
708 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
709 results in autocomplete ignoring prefix text.
710
711 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
712 entering a new name into the text box.
713
714 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
715 Firebird rather than recomputing it.
716
717 8. Property Editor positioning tidy up: All IBX Property editors should now be
718 screen centre. Previously some were "poDesigned" which may be inappropriate
719 for multi monitor desktops.
720
721 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
722
723 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
724 a transaction and always reset the object.
725
726 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
727
728 13. TIBXScript: Allow for override of database filename in Create Database statements.
729
730 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
731 to a gbak format archive.
732
733 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
734
735 16. IBLocaldb: Drop database if error creating an empty database.
736
737 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
738 unless selected node not in current dataset.
739
740 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
741 to TIBCustomService, and IBlocalDB code tidy up.
742
743 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
744 behaviour due to uninitialised variable.
745
746 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
747 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
748
749 21. IBSQL: When Database changed ensure that all resources are freed.
750
751 22. IBCustomDataset: When database changed ensure that queries an unprepared.
752
753 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
754 * Line Wrap on SQL Token boundaries (on user command)
755 * auto-complete table names in drop down list of table names
756 * Double click on tablename or field name adds to SQL text
757
758 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
759
760 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
761 TVariantArray. Seems to avoid memory corruption in Windows (probably a
762 workaround for a problem in fpc 3.0.4 win64).
763
764 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
765
766 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
767
768 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
769
770 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
771 include remote system name.
772
773 2. TIBExtract: No longer include comment header and COMMIT statement for empty
774 tables when data included in output.
775
776 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
777 and timing information to be written to stdout. This may be used to locate
778 performance bottlenecks.
779
780 4. SQLParser: only call "OnChanging" event handler when value is different.
781
782 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
783
784 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
785 that BindFields is called when the query is next activated. Avoids FieldName
786 not found error.
787
788 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
789 purpose and allows the programmer to define any action they want for Update, Insert
790 or Delete. This may be complex SQL (similar to a Trigger), application specific
791 filtering of updates, or use of statements such as Grant or Revoke instead of
792 normal DML. See User Manual for more information.
793
794 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
795
796 1. TIBEvents: Fix uninitialised variable that could result in lost events.
797
798 2. TIBExtract: Added support for FB3 "USAGE" privilege.
799
800 3. TIBExtract: data formatted as Charset set "octets" is now output using
801 hexadecimal notation.
802
803 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
804 using a simple XML format.
805
806 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
807 grants to these objects.
808
809 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
810 dependency problems restoring complex databases.
811
812 7. TIBXScript: This component has been restructured to allow for the processing of
813 embedded XML in INSERT statements and to support interactive sources in addition
814 to non-interactive data sources such as files.
815
816 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
817
818 9. TIBXScript: ISQL compatiable Set statements are now supported:
819 SET SQL DIALECT
820 SET TERM
821 SET AUTODDL
822 SET BAIL
823 SET ECHO
824 SET COUNT
825 SET STATS
826 SET NAMES <character set>
827
828 10. IBVersion unit added to hold current IBX Version Number information.
829
830 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
831 and domain definitions.
832
833 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
834 fully supported.
835
836 13. TIBExtract: when a database dump includes data, the generator values are now also set.
837
838 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
839
840 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
841
842 See also doc/IBX4LazarusGuide.pdf for important information on
843 upgrading to IBX2.
844
845 1. Size property of TIBStringField is now the width in characters of the field
846 and not the byte length. This applies only to multi-byte character sets such
847 as UTF8. The original approach aligned with TStringField. However, the TStringField
848 code is not recognised as a bug and hence this change to align the behaviour.
849 The TStringField change is expected in fpc 3.2.0.
850
851 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
852 true (default) then Size property value saved in the lfm is ignored. Size is
853 always set from the dynamic information read from the database. It is unclear
854 why anyone would want to override this and set Size to false.
855
856 3. ibxscript: should now handle correctly a Case..End statement within a procedure
857 block.
858
859 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
860 exist when an attempt is made to connect to it (run time only) then an attempt
861 is made to create the database.
862
863 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
864 has been successfully created as a result of a call to CreateDatabase or when
865 creating a database after it was found not to exist.
866
867 6. DBControlGrid: a race condition could result in the wrong row image being
868 written to the cache. This has been avoided by a trip round the message
869 loop before rendering the row image.
870
871 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
872 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
873 known to risk corrupt rendering of row images when the control is first
874 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
875 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
876
877 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
878 a TDateEdit control located on an editor panel.
879
880 9. TIBExtract: brought up-to-date plus many bug fixes.
881
882 10. DBControlGrid: Removed memory leak when updating rows.
883
884 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
885
886 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
887
888 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
889 when target codepage is CP_NONE. This is a workaround for
890 http://bugs.freepascal.org/view.php?id=30622.
891
892 2. DBLog option removed from TIBStatisticalService - not supported by server
893 since Firebird 1.5.
894
895 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
896 similar.
897
898 4. IBCodePage: updated mapping between codepages and character id.
899
900 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
901 Firebird. Character sets with a char width of two are not UTF16.
902
903 6. Strings received from the database are now always transliterated into UTF8
904 regardless of the database character set or connection character set. This
905 is for compatibility with the LCL.
906
907 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
908
909 1. IBBlob: Defer reading of blob until read method called. This avoids having to
910 read in an entire blob just to get the size of the blob. General performance
911 improvement when opening datasets containing blobs.
912
913 2. Clearing a Blob now sets the corresponding field's modified flag.
914
915 3. IBLookupCombo: When not performing auto-complete, original query sort order
916 is now used.
917
918 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
919 determined.
920
921 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
922
923 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
924 lazarus 1.6.0
925
926 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
927 compilation error.
928
929 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
930
931 1. No character set specified for connection: when a text blob is retrieved, the
932 character set is determined by looking up the native character set using then
933 Firebird API. Otherwise a text mode blob is assumed to have the same character
934 set as the connection.
935
936 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
937 for Login Dialog returing a change to the database path.
938
939 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
940 to be changed from that given in the TIBDatabase/TIBServer component and for the
941 entered value to be saved on a project specific basis (design time only).
942
943 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
944 column fieldname. If they are the same then it is acts as a look up for the KeyValue
945 Otherwise, it sets the column text to the selected ListField Value.
946
947 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
948 column width.
949
950 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
951 and a case insensitive search is requested.
952
953 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
954 or column ListSource.
955
956 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
957 unprepare) when closing and the text has not changed.
958
959 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
960 Less likely to cause a cursor re-use error on Windows.
961
962 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
963 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
964
965 11. TIBTreeView: Guard against nil destination on record changed
966
967 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
968 string type with the code page set to reflect the returned field encoding after
969 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
970 earlier versions.
971
972 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
973 will now result in transliteration to the code page specified for the Firebird driver
974 if the assigned string has a different code page. FPC 3.0.0 onwards only.
975
976 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
977 is ignored and the lc_ctype value, when the database is opened, is set to align with
978 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
979 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
980 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
981 the GETACP is used to determine the Windows code page.
982
983 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
984 name used as the lc_ctype when the database was opened. Only valid while the
985 Database is connected.
986
987 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
988 id that corresponds to the DefaultCharSetName.
989
990 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
991
992 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
993 path is given and database attach fails due to access permission issues on the
994 temp directory or security database, then the attach is retried with "localhost:"
995 prefixing the databasename. This should avoid problems when the database has to
996 be accessed by a local (e.g. classic) server and libfbembed is used.
997
998 2. Windows: revised search order for Firebird DLL:
999 i. The Firebird Embedded Server in the application Directory.
1000 ii. If the FIREBIRD environment variable is set then the directory this
1001 points to is searched for the FB Client DLL and then then underlying
1002 "bin" directory.
1003 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1004 is used to locate the Firebird installation directory and the underlying
1005 "bin" directory is searched for the FB Client DLL.
1006 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1007 are searched for the FB Client DLL.
1008 v. The PATH Environment variable is used to search for the FB Client DLL.
1009 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1010
1011 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1012 See doc/readme.scriptengine and example applications.
1013
1014 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1015 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1016 See dpc/readme.localdatabase and example applications.
1017
1018 5. IBDynamicGrid: Reordering on column header click should now also work for
1019 dynamic columns.
1020
1021 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1022 between incrementing/decrementing the lock count and signalling the event.
1023
1024 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1025
1026 1.3.2 was never formally released and only made available as beta copies.
1027
1028 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1029
1030 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1031
1032 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1033
1034 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1035 i.e. when it is a calculated field
1036
1037 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1038 This problem was due to a race condition between recalculating row heights and
1039 determining which row was selected by the mouse click. The row height calculation
1040 is now deferred by an extra trip round the message loop allowing the row to
1041 be always calculated on the current grid layout rather than risking it being
1042 calculated on the grid layout after the expanded row has been shrunk.
1043
1044 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1045 Windows.
1046
1047 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1048 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1049 to be determined at runtime. See doc/readme.charactersets.html.
1050
1051 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1052 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1053
1054 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1055 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1056 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1057
1058 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1059 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1060 implies no truncation.
1061
1062 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1063
1064 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1065 (avoids "Not in Edit Mode" error).
1066
1067 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1068
1069 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1070 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1071
1072 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1073
1074 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1075
1076 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1077
1078 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1079
1080 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1081
1082 1. OnCloseUp Event Handler added to TDBLookupProperties
1083
1084 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1085 problem with row size when exception is called.
1086
1087 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1088
1089 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1090 in a TCustomComboBox and ignores return key if in a TCustomMemo
1091
1092 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1093 keyed in i.e. when autocomplete not performed
1094
1095 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1096 console mode applications with all LCL required functions (builtin dialogs and
1097 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1098 not included in your project, IBX should compile and link with a console mode program.
1099 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1100 console mode application or the IDE will automatically assume that your
1101 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1102
1103 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1104 to use the built in dialogs and cursor management. IBDialogs is
1105 included by default if "ibexpress" is in your project source's "uses" clause.
1106 This should be the case for all projects created through the IDE. This is why
1107 you do not want to add the ibexpress package to console mode applications. The
1108 ibexpressconsolemode package has been created to allow console mode programs
1109 to avoid adding LCL dependencies when using IBX, while still having the
1110 unit search paths set up correctly.
1111
1112 Existing users should check to ensure that the "ibexpress" unit is included in
1113 each project's source file (*.lpr).
1114
1115 You may find that in order for the IDE to recognise that ibexpressconsolemode
1116 exists, you have to first open the package in the IDE and then close it. This
1117 adds it to the most recently accessed packages list. To make it permanently
1118 available, add the package name to lazarus' staticpackages.inc file.
1119
1120 Thanks to Julio Jiménez for suggesting support of console mode.
1121
1122 7. SQL Parser can now accept quoted strings that include new lines
1123
1124 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1125 of text on start of edit. This is particularly useful when tabbing to a
1126 column and then inserting text.
1127
1128 9. New Examples provided for IB Services and ISQLMonitor.
1129
1130 10. Fix error when writing to blob streams that recorded only the last buffer
1131 write in the blob stream. In most cases, this did not cause a problem as the
1132 IB Blob Stream is written in a single write. However, with the TDBImage, write
1133 of a graphic type prefix was lost which caused a problem when the image could
1134 not be automatically recognised.
1135
1136 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1137 already open" errors due to random numbers used for the cursor name being identical.
1138
1139 12. IBTable: corrected error that could result in an "Index out of bounds" error
1140 when opening the table and the Primary Key is the last or only column in the
1141 table. Thanks to Rick Hoover for the fix.
1142
1143 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1144 of "UTF-8", and update list of available database character sets. Existing
1145 users should check the current lc_ctype setting in their applications.
1146
1147 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1148
1149 1. Firebird Services: avoid List Index error when opening a service with an
1150 empty Params property.
1151
1152 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1153 Link now set up in Loaded method - avoids occasional failure to apply
1154 SQL markup on initial open.
1155
1156 3. "Employees" example performance improvements when scrolling.
1157
1158 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1159 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1160 random image cached).
1161
1162 5. DBControlGrid: Should now react to changes in panel height at run time.
1163
1164 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1165 even when further rows exist.
1166
1167 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1168 always be derived from panel height and setting this property can cause confusion.
1169 Note for existing projects: to avoid a missing property error at run time,
1170 each form using the DBControlGrid must be opened, updated and saved in the IDE
1171 in order to remove the property value from the lfm.
1172
1173
1174 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1175
1176 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1177 call Prepare before setting parameter values.
1178
1179 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1180
1181 3. Code tidyup and more robust handling of dsql information result vector.
1182
1183 4. Support for centralised handling of transaction status changes. TIBTransaction
1184 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1185 and "AfterExecQuery". The first three are called after the same event is called
1186 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1187 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1188 enable monitoring of transaction status changes for a given transaction to be
1189 handled in a single place. For example, when a change to the dataset occurs
1190 an indicator can be set that shows the user that in order to save changes,
1191 the transaction should be committed. Rather than doing this per dataset, this
1192 can now be done per transaction.
1193
1194 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1195 the dataset is scrolled. However, any changes to the current row are, by default,
1196 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1197 have a new property "DataSetCloseAction" that adds automatic posting of changes
1198 on dataset close. If this property is set to dcDiscardChanges (default) then the
1199 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1200 then IBX will attempt to post any unsaved changes before the dataset is closed
1201 (and after the BeforeClose event handler is called). The exception is when the
1202 dataset is being closed as a result of a transaction rollback. In this case,
1203 no action is taken and any unsaved changes are discarded. This avoids both
1204 unnecessary overhead and the risk that a validation error may occur in the Post
1205 raising an exception and thereby preventing a rollback.
1206
1207 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1208 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1209 width. Display Widths are now corrected by dividing by the max byte width per character.
1210 For UTF8 character sets, the byte width is four and hence the Display Width will be
1211 the byte width divided by 4. The byte width of each character set is determined
1212 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1213 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1214
1215 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1216
1217 8. IBLookupComboEditBox: List should now always be restored to full list when the
1218 control loses focus. Default Key press default interval reduced to 200ms.
1219
1220 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1221 when dataset rows are less than visible rows.
1222
1223 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1224 does not exist or DataSet is empty. More responsive on dataset open. New event
1225 OnRestorePosition. Column sort disabled if no header row.
1226
1227 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1228 while dataset state is dsInsert. Avoids posting errors.
1229
1230 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1231 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1232
1233 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1234
1235 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1236 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1237 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1238 always "posts" the current record regardless or whether or not it may be more appropriate
1239 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1240 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1241 as the first action of the "Post" method and allows the handler to convert the Post
1242 into a Cancel if that is the appropriate action on moving to a different row. This is
1243 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1244 raised here, but it may still be more appropriate to validate a post and signal
1245 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1246
1247 15. On Unix derived systems, the Firebird library name can now be given as a colon
1248 separated list. Each library name on the list is tried in turn, in left to right
1249 order with the first found being used as the firebird library. By default, on Linux,
1250 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1251 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1252
1253 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1254 then it will still attempt to access the database via the Firebird Server and will
1255 require a username and password. If only the pathname is given, then the username
1256 and password should be omitted and the unix file permissions are used to grant
1257 access.
1258
1259 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1260
1261 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1262 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1263 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1264 corresponds to a row of the linked DataSource. Any data aware control on the
1265 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1266
1267 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1268 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1269 takes place during database access. This may be useful when there are performance issues with
1270 the change of cursor. Setting the property to false suppresses the change of cursor.
1271
1272 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1273 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1274 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1275 making all changes permanent immediately rather than when the transaction is explicitly
1276 committed.
1277
1278 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1279 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1280
1281 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1282
1283 Development version only.
1284
1285 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1286
1287 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1288 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1289 "Where" and "Having" clauses to implement user specified filters of arbitrary
1290 complexity.
1291
1292 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1293 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1294 These are:
1295
1296 - TIBLookupComboEditBox
1297 - TIBDynamicGrid
1298 - TIBTreeview
1299
1300 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1301 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1302 to revise the available list and restrict it to items that are prefixed by the
1303 typed text (either case sensitive or case insensitive). Autoinsert allows a
1304 newly typed entry to be added to the list dataset and included in the available
1305 list items.
1306
1307 TIBDynamicGrid is a TDBGrid descendent that provides for:
1308 - automatic resizing of selected columns to fill the available row length
1309 - automatic positioning and sizing of a "totals" control, typically at the
1310 column footer, on a per column basis.
1311 - DataSet resorting on header row click, sorting the dataset by the selected column.
1312 A second click on the same header cell reversed the sort order.
1313 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1314 is automatically expanded and a panel superimposed on it. The panel can have any
1315 number of child controls, typically data aware controls with the same datasource
1316 as the grid allowing for editing of additional fields and more complex editors.
1317 - Reselection of the same row following resorting.
1318 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1319 Its properties are specified on a per column basis and allows for one or more
1320 columns to have their values selected from a list provided by a dataset.
1321 Autocomplete and autoinsert are also available. The existing picklist editor
1322 is unaffected by the extension.
1323
1324 TIBTreeView is a data aware TCustomTreeView.
1325
1326 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1327 zero scale will no longer return an error. An Int64 will be returned instead.
1328
1329 4. TIBTransaction now has events for Before and After Transaction End and a new function
1330 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1331
1332 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1333 repeated multiple times.
1334
1335 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1336 check used to get in the way of using Stored Procedures, and "Update or Insert"
1337 statements.
1338
1339 7. Insert, Modify and Delete property Editors now support Query Generation from
1340 Stored Procedures.
1341
1342 8. Three new examples illustrate the use of the new IB Controls
1343
1344
1345 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1346
1347 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1348 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1349 Gabor Boros for reporting this problem and for testing the improvements).
1350
1351 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1352 See readme.field+param.names in the doc folder.
1353
1354 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1355 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1356
1357 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1358
1359 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1360 actions.
1361
1362 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1363 thanks to Yuriy Kopnin for pointing this out).
1364
1365 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1366
1367 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1368 for both fields and parameter setting.
1369
1370 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1371 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1372
1373 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1374 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1375
1376 11. TIBTable now has a property editor for "MasterFields"
1377
1378 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1379 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1380
1381 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1382 of settings is unrecognised. Selecting this radio button has no effect on the settings.

1391 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1392 it is null. This allows for alternative user defined setting of the generator
1393
1394 Many thanks to Julio Jiménez for this fix
1395
1396 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1397 and suggests that the user may have forgotten to install it.

1402 Lazarus versions less than 1.1
1403
1404 2. When a database connection is created, character set is now by default set

1415
1416 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1417 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1418
1419 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1420 package is changed to do this (which it should do).
1421

1424 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1425
1426 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1427
1428 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1429
1430 4. Property editors should now correctly resize.
1431
1432 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1433 (restored original functionality)
1434
1435 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1436 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
