1 IBX Change Log version (2.4-3 Build 12796) Mon, 06 Sep 2021 11:26:41 +0100
2
3 1. Add try-..except check when initially loading library in IDE. This should
4 ensure that IDE continues to load even when a failure occurs in IBX load
5 library.
6
7 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
8
9 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
10 exception of those defined to be one byte wide e.g. DBImplementationNo.
11
12 2. TIBSQL: Batch Update/Insert support added.
13
14 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
15 is no longer automatically converted to upper case when it is syntactically a
16 SQL Identifier. This is to support the use of stored procedures defined e.g.
17 as CREATE PROCEDURE "iCASE".
18
19 There could be a backwards compatibility issue when the StoredProcName was entered
20 manually at design time. That is not selected from the drop down list. If the
21 StoredProcName is entered in mixed case and the procedure was declared e.g. as
22 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
23 ensure that the value of the StoredProcName is all upper case, unless it was
24 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
25 quotes).
26
27 Note that when a stored procedure name was declared delimited in double quotes,
28 as in the first example above, the value of the StoredProcName property must not
29 include the delimiters (double quotes).
30
31 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
32 upgrade.conf was not found. This replaces silently ignoring the problem.
33
34 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
35 'Version.%.3d' and is used to generate the section header names (for a given
36 version no.) in the upgrade.conf file.
37
38 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
39
40 1. -c command line option added to fbsql example program. Used to set connection
41 character set.
42
43 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
44
45 1. Firebird 4 support added.
46
47 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
48 extended precision NUMERIC fields are supported.
49
50 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
51
52 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
53 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
54
55 5. IBExtract now supports FB4 enhancements:
56 - new data types as above
57 - Identity column extensions
58 - Default user role
59 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
60 - Internal Functions
61
62 6. IBExtract: new event: OnExtractLines.
63
64 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
65
66 8. IBXServices: Server version no. parsing now allows any letter before major version number
67 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
68
69 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
70 format for rendering a time zone.
71
72 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
73 to convert TIME WITH TIME ZONE data type values to and from GMT.
74
75 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
76 IIBGUIInterface and IIBTimerInf respectively.
77
78 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
79 now accessible as properties of TIBDatabase and TIBTransaction respectively.
80
81 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
82 truncated to its fixed character width rather than being right padded with
83 white space to the maximum data size.
84
85 14. TIBTable.Empty table. In additional to deleting all records in the underlying
86 table, the internal buffers are now also flushed ensuring that the TIBTable is
87 also empty.
88
89 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
90
91 16. TIBXControlService descendents: DatabaseName may now be set using a database
92 connect string. The database name is extracted from the connect string.
93
94 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
95
96 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
97
98 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
99 not being present as required.
100
101 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
102 version that can be customised to work with other database drivers.
103
104 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
105 unnecessary CR at end of line on Unix platforms.
106
107 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
108 seconds in order to reduce risk of message loss.
109
110 23. ISQLMonitor: read and write count statistics now available via:
111 property TIBSQLMonitor.ReadCount;
112 IIBSQLMonitorHook.GetWriteCount: integer;
113
114 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
115
116 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
117
118 1. TIBStringField: when a string value is read from a dataset buffer, if the
119 number of UTF8 characters exceeds the string size then string is truncated
120 to the maximum string size. This is usually a problem with fixed width columns
121 right padded with white space.
122
123 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
124 If SQLFiltered is set then when a dataset is opened, each line in the
125 SQLFilterParams property is assumed to be a SQL condition clause and
126 ANDed into the Where clause of the SQL Select statement provided as a
127 dataset property. Each such SQL condition thus acts as an additional filter
128 on the dataset.
129
130 3. The Filtered property inherited from TDataset is no longer used for SQL (server
131 side filters).
132
133 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
134 text matches complete entry.
135
136 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
137 dataset are active (avoids risk of access violation if master is inactive)
138
139 6. TIBEvents: Registered property can now be set at design time even if database not open
140
141 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
142 This should prevent "spillover" of events between sessions.
143
144 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
145 This should ensure that the internal buffer is set up correctly and avoids
146 a duplicate initial row.
147
148 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
149 That is, the DataSize should be the field size * character set width. The
150 value returned by DataSize is now the same as the Dataset buffer size reserved
151 for the field.
152
153 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
154
155 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
156 and vice-versa. This may result in an exception being raised (correctly) for
157 older programs when using dataset fields added to a form and the database has been
158 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
159 In such cases, the field needs to be deleted in the IDE fields editor and then
160 added back in.
161
162 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
163 false if query contains only white space and not just empty.
164
165 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
166 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
167 is cancelled.
168
169 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
170 called on a null field.
171
172 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
173 results in an empty dataTC86 Client side Filtered Dataset 1 X
174 set.
175
176 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
177 a cached update is applied and an exception is raised.
178
179 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
180
181 17. Console Mode Local Database support: backup/restore should now work correctly.
182
183 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
184 possible and an exception raised.
185
186 19. MinimumVersionNo added to Local Database Support. Database will not open if
187 below this version no. and upgrade not possible.
188
189 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
190
191 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
192 not SQL Identifiers are now supported.
193
194 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
195 passed to the Firebird engine for execution.
196
197 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
198 is made to scroll back.
199
200 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
201
202 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
203 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
204
205 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
206 validated. If no match is found in the list of field names and the database has
207 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
208 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
209
210 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
211 with fpc 3.2.
212
213 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
214
215
216 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
217 and is used to override the default settings in the client side "firebird.conf" This
218 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
219 Each line of the string list should be a setting in the same format as "firebird.conf".
220 For example "WireCompression = true" in order to request wire compression on the client side.
221
222 Note: explicit settings in the client side "firebird.conf" appear to take precedence
223 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
224 also require a compatible setting in the server side "firebird.conf". For example
225 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
226 compression to be used.
227
228 Whether or not WireCompression or WireCrypt are in use can be checked using the information
229 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
230 ibx/examples/dbinfo for examples of how to display this information.
231
232 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
233 is a "convenience" property. If set the "WireCompression=true" is added to the
234 ConfigOverrides. If unchecked then this setting is removed.
235
236 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
237 not "INT64".
238
239 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
240 These are:
241 property TimestampFormat: string;
242 property DateFormat: string;
243 property TimeFormat: string;
244
245 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
246 DATETIME and TIME. The format strings use the standard FPC date/time format
247 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
248
249 If any of the above properties are set to an empty string, then the locale default
250 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
251 locale default is extended by appending '.zzz' to include milliseconds.
252
253 TIBCSVDataOut by default sets these properties to the empty string, while the other
254 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
255
256 5. New published property for TIBCSVDataOut:
257 property QuoteStrings: boolean (default true)
258
259 If false then strings are unquoted, otherwise, the QuoteChar property value is
260 used to delimit each and every string in the output.
261
262 6. New published properties for TIBCSVDataOut:
263 property FieldSeparator: string;
264 property HeaderSeparator: string;
265
266 Respectively, these provide the separator character(s) used to separate fields
267 in data and header rows. Both default to ','.
268
269 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
270 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
271 property OnFormatTextString;
272
273 This event handler can be used to process text strings before they are included
274 in the output e.g. to replace unprintable characters with alternative strings.
275 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
276
277 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
278 Uses "FindParam" if in order to find out if a parameter with a given name exists
279 and without raising and exception if it does not.
280
281 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
282 consistency with SQL queries.
283
284 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
285 When true, SQL statement parameter names are parsed case sensitive. Note for
286 TIBDataSet only applies to Select query.
287
288 11. IBEvents: removing a TIBEvent component from a form should no longer result in
289 an IDE exception.
290
291 12. LocalDBSupport: initial database creation should now work correctly
292 when the schema source is an sql file.
293
294 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
295 when defined, this handler will be called by the internal TIBXScript during
296 initial database creation when the schema source is an sql file and may be used
297 to provide a visual indication of progress in console mode.
298
299 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
300 to true while a new local database is being created and its schema populated.
301 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
302 when the database is disconnected/connected during the create DB procedure.
303
304 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
305 are now always ignored and replaced by the user name and password provided as
306 the login parameters for the TIBDatabase referenced from the TIBXScript. The
307 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
308 completely ignored if this property is true.
309
310 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
311 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
312 ImageIndex and SelectImageIndex values on AddNode.
313
314 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
315 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
316 the same database connection.
317
318 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
319 if provided, this should be an conditional SQL expression suitable for
320 including in an SQL Select statement "where" clause. If non-empty and the
321 "Filtered" property is true then the SQL expression provided as the value of
322 the "Filter" property is "ANDed" with any existing condition statement
323 in the SQL statement's "Where" clause.
324
325 If the "Filter" property is set at run time, the "Filtered" property is true
326 and the dataset is already open, then the dataset is closed and re-opened automatically.
327
328 The "Filter" condition may include IBX style parameters. In which case, their
329 value must be set by the dataset's "OnBeforeOpen" event handler.
330
331 This is a public property for TIBDataSet and TIBQuery query and intended for
332 use at run time.
333
334 Note: The property is a published property of TIBTable. The TIBTable functionality
335 is unaffected by this change.
336
337 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
338
339 1. Remove need to check for IsMultiThread by providing access to GUI timers via
340 IBGUIInterface. Note: master/detail delay timer does not apply to console
341 mode apps.
342
343 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
344 statement. This avoids problems if "Execute Block" is used as the Query.
345
346 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
347 internal SQL tokeniser routines.
348
349 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
350 as a select statement, with or without CTEs.
351
352 5. IBSQLParser: parser now recognises the "ROWS" clause.
353
354 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
355 internal SQL tokeniser routines.
356
357 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
358 being raised for valid set statements processed by a data formatter.
359
360 8. New published property for TIBDatabase and TIBXServicesConnection. This is
361 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
362 the path of the Firebird Library used by the database/services connection.
363
364 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
365 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
366 services connection.
367
368 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
369 or param name is not a valid SQL identifier.
370
371 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
372 view of whether the text box should be editable when no DataSource is specified.
373 TIBLookupComboEditBox has been updated to workaround this problem. As long as
374 ReadOnly is false, the text box is editable when no DataSource is specified.
375
376 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
377 the FBLIB environment variable. If you do not want to permit this then you
378 must modify the Register procedure in the design/IBDBReg.pas unit to remove
379 this setting.
380
381 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
382
383 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
384 Utf8EscapeControlChars
385
386 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
387
388 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
389 all previous copies of the IBX source code tree before installing this release.
390
391 The IBX packages used by most users have not changed, with one exception. The
392 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
393 to use the IBServices unit in your applications, please add the iblegacyServices
394 to the list of dependencies. To do this, open the Project Inspector and select
395 Add->New Requirement and select "ibLegacyServices" from the list of available
396 packages.
397
398 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
399 the IBServices unit providing what is intended to be a clearer and easier to
400 use set of IB Services components. See Chapter 10 of the IBX User Guide for
401 more information and the guide to "Firebird Service Management Using IBX".
402 As indicated above, the legacy services components are still available and
403 provided in a separate package. There is no need to update working applications
404 using the older versions except for an additional package dependency.
405
406 2. The IBX packages and source code tree have been re-organised in an attempt to
407 finally get rid of the "duplicate ppu" warnings. This re-organisation should
408 not affect existing users. Section 2.3 of the IBX User Guide describes the
409 new set of IBX packages.
410
411 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
412 updated to use the new Services API components.
413
414 4. The iblocal package has been updated to use the new Services API components.
415
416 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
417 TIBXSecurityService. It had been wrongly classified in the previous version
418 as a per database configuration item. It is global to a server and hence
419 correctly positioned as part of the Security Package. In the DBAdmin example,
420 the setting has moved to the mappings page.
421
422 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
423 are ignored.
424
425 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
426 closed before the database is dropped. Before and After Disconnect event handlers
427 are also fired.
428
429 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
430 is started and not just the first time.
431
432 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
433 depenendency with comp type.
434
435 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
436
437 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
438 then this is recognised and not ignored.
439
440 12. TIBDataSet, TIBQuery, TIBTable: additions:
441 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
442 function GetPerfStatistics(var stats: TPerfCounters): boolean;
443 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
444
445 GetRowsAffected returns the affected row counts from the last insert/update/delete
446 if EnableStatistics = true then GetPerfStatistics returns the current stats
447 counters for the select query. Note: stats accumulate after each fetch from
448 the database. To get total query cost after open, call the "Last" method
449 and then GetPerfStatistics.
450
451 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
452
453 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
454 in parenthesises.
455
456 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
457 SQL identifiers are always delimited by double quotes. If false, then they are
458 only delimited if the identifier is a reserved word, contains lower case or special
459 characters. Set this property to true to retain previous behaviour.
460
461 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
462 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
463
464 16. TIBDataSet, TIBQuery, TIBTable: addition:
465 property MasterDetailDelay: integer {defaults to zero}
466
467 When non-zero and the dataset is a detail table referencing a master table
468 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
469 then a synchronisation delay is added (in milliseconds) between the master
470 row changing and the detail dataset being re-opened. If the master dataset
471 is scrolled before the delay expires then the delay is reset. This can be used
472 to avoid performance overheads when scrolling through a large master dataset.
473
474 Note: uses fptimer and hence requires a thread manager. Under Linux the
475 chreads unit must be included in your project. TTimer is not used in order
476 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
477
478 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
479 with Extract Option eoDatabase.
480
481 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
482 When a deLayoutChanged event is reported on the ListSource dataset, the
483 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
484 relationship with the control's datasource (master).
485
486 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
487
488 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
489 stubs. Pedantic fix really, as procedures output in dependency order anyway.
490
491 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
492 DDL (Firebird 3 and later only).
493
494 22. TIBLookupComboBox Autocomplete Fixes:
495 i. Only appended text is now selected after autocomplete.
496 ii. Uppercase keys no longer ignored for autocomplete.
497 iii. Retain Prefix case is now honoured correctly.
498 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
499 before autocomplete performed. i.e. behaviour now the same as when
500 no DataSource assigned.
501
502 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
503 between SQL statements.
504
505 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
506 ObjectNames are converted to upper case before matching against metadata object
507 names, unless the objectname is delimited by double quotes, in which case, the
508 double quotes are removed and the remaining string is used (unmodified) to match
509 against the metadata object name.
510
511 If true then the ObjectName is used as is without modification and matched
512 against the metadata object name. No attempt is made to remove double quotes.
513
514 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
515 with eoTrigger, these extract types can be used to select only Database Triggers,
516 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
517
518 26. TIBXScript: If an exception occurs during the processing of a statement, the
519 statement separate character is now reset to the default (';').
520
521 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
522
523 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
524 a commit or reconnect statement and instead activated only when next SQL statement
525 is executed.
526
527 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
528
529 30. TIBXScript: case insensitive regex now used when matching statements instead of
530 converting statement to upper case.
531
532 31. TIBExtract: metadata comments now supported. New published property
533 IncludeMetaDataComments (default true). If true then metadata comments included
534 in extracted DDL. New Extract Object member eoComments. This may be used with
535 ExtractObject method to list all metadata comments.
536
537 32. TIBExtract: ListObjectNames method added.
538
539 33. Updated Database component editor to support additional connection string
540 types.
541
542 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
543
544 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
545 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
546 RELEASE.
547
548 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
549
550 1. IBExtract: Identity columns - add additional check for null column for generator name.
551
552 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
553 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
554 information). However, this is also a very useful mechanism for returning updated computed by
555 column values. Values returned as a result of executing an Insert or Update statement
556 replace existing values in the current row for each corresponding column.
557
558 Previously, if a dataset's select query included read only (computed by) fields then
559 an automatic row refresh was performed after an insert or update query had been processed,
560 irrespective of the setting of the "ForcedUpdates" property. This has changed such
561 that an automatic refresh is no longer performed if an insert or update query contains
562 a returning clause that updates one or more fields on the current row. A full row
563 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
564 field values and the select query contains read only fields. Use of Insert/update
565 returning should be significantly more efficient than executing a refresh query.
566
567 This behaviour change is intended to be backwards compatible and there should be no need to change
568 existing programs, other than to improve performance by using the new capability.
569
570 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
571 they are called when the dataset row is being deleted, there is no value in
572 updating the current record from the query result. Instead, a new event handler
573 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
574 an OnDeleteReturning event handler is provided then it is called with the IResults returned
575 by the query. The event handler can then interrogate the query results and
576 perform whatever action is necessary. For example to confirm, to the user,
577 the deletion of a row with the returned values.
578
579 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
580 any Computed By or Identity Columns. The IBTables example has been updated to
581 illustrate the computation of the employee Full Name on update.
582
583 5. TIBTable: The GeneratorField property is now published.
584
585 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
586 When InsertSQL is generated, the Identity columns are not included in the list of values to
587 be inserted. A RETURNING clause is added to the insert statement to return the value of
588 each Identity column after the insert is executed.
589
590 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
591 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
592 Insert..Returning clause.
593
594 8. TIBGenerator: small performance improvement by not preparing query each time
595 a new value is generated.
596
597 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
598
599 10. Property editors will now sync table name to a System Table when "Include System
600 Tables" is selected and the query is for a System Table.
601
602 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
603 values are no longer converted to milliseconds from TDateTime and then back again
604 to TDateTime (the conversion to milliseconds is the default TDataset approach).
605
606 12. Property Editors handling of Stored Procedures.
607 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
608 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
609 query).
610 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
611
612 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
613 can be used to select a package. If non-empty, the stored procedure name is
614 expected to be a stored procedure defined in the specified package and the
615 generated SQL will be as required for a stored procedure located in a package.
616
617 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
618 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
619 which a stored procedure can be selected. With no package name selected, non-package
620 stored procedures are listed.
621
622 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
623 for password on reconnect.
624
625 16. TIBDatabase: use IAttachment for connection default character set id, code page
626 and character set name.
627
628 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
629 DB info lookups"
630
631 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
632
633 19. Add a property Editor for TIBUpdate.RefreshSQL.
634
635 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
636 parameters. This stops an exception being raised when the field cannot be
637 located in the record buffer.
638
639 21. Property Editors now automatically include System Tables when opened and when the query table
640 is a System Table.
641
642 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
643 This avoids errors due to a stale SQRB or SRB being used for the next query.
644
645 23. IBServices: Service attach parameters now include "expected_db". This is used to
646 add the SPB item isc_spb_expected_db. This names a database using
647 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
648 database. examples/services re-written to illustrate use of "expected_db".
649
650 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
651 This avoids truncated backups when the server returns a timeout (busy) response.
652
653 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
654
655 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
656 databasenames. These are respectively expanded to the local system's temp directory
657 (including trailing delimiter) or to a prescribed data directory (including
658 trailing delimiter). Under Unix systems the data directory is a hidden directory
659 in the user's home directory. The hidden directory name is either the string returned
660 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
661 Under Windows, the directory is the same as the Data Directory as decribed
662 above but instead prefixed by the User's application data path. These may be
663 used to improve application portability for Personal Databases.
664
665 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
666 this has not worked for a long time and is not useful either. FieldDefs should be
667 managed using the Fields Editor as with any other dataset. To access the fields
668 editor for a TIBTable component, double click on the component. The fields editor
669 is then displayed.
670
671 28. TIBDatabaseInfo: new properties/function
672 * DateDBCreated (returns date/time database created)
673 * TransactionCount (returns no. of active transactions)
674 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
675 * PagesFree (Firebird 3 or later)
676 * PagesUsed (Firebird 3 or later)
677 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
678 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
679
680 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
681
682 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
683
684 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
685 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
686
687 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
688 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
689 firing during backup and restore.
690
691 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
692 for verbose output using the new property "StatisticsRequested".
693 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
694
695 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
696
697 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
698 palette. This uses the online validation feature added in Firebird 2.5. The
699 services's properties enable inclusion/exclusion of tables and indexes using
700 regular expressions. See.
701 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
702
703 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
704 option on a database.
705
706 37. TIBCustomService: Assign method implemented to allow copying of service login
707 context between service API components. "Detach" method now only detaches
708 service when last reference to the service interface detaches. Tidy up of
709 code for SetActive and Attach methods including password hiding.
710
711 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
712 and used to determine the auth method and protocol used for the connection.
713
714 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
715 a Create Database Statement generated by IBX.
716
717 40. All IBServices now have an additional published property "PortNo". This may
718 be set to a non-standard port number when necessary. If zero then the default
719 port number is used.
720
721 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
722 and not just the mouse.
723
724 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
725
726 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
727 image index and selected image index for each node to be set from a database field.
728
729 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
730 then database schema includes grants to all users. If not present then the
731 only user grants included are those to User PUBLIC.
732
733 45. TIBTreeView: performance improvement. When expanding include both expanded node
734 and child nodes in dataset.
735
736
737 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
738
739 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
740 changes.
741
742 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
743 Bug could result in truncated multi-byte character set values.
744
745 3. Changes consequential on moving fbintf character set utility functions from
746 IFirebirdAPI to IAttachment.
747
748 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
749
750 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
751 results in autocomplete ignoring prefix text.
752
753 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
754 entering a new name into the text box.
755
756 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
757 Firebird rather than recomputing it.
758
759 8. Property Editor positioning tidy up: All IBX Property editors should now be
760 screen centre. Previously some were "poDesigned" which may be inappropriate
761 for multi monitor desktops.
762
763 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
764
765 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
766 a transaction and always reset the object.
767
768 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
769
770 13. TIBXScript: Allow for override of database filename in Create Database statements.
771
772 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
773 to a gbak format archive.
774
775 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
776
777 16. IBLocaldb: Drop database if error creating an empty database.
778
779 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
780 unless selected node not in current dataset.
781
782 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
783 to TIBCustomService, and IBlocalDB code tidy up.
784
785 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
786 behaviour due to uninitialised variable.
787
788 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
789 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
790
791 21. IBSQL: When Database changed ensure that all resources are freed.
792
793 22. IBCustomDataset: When database changed ensure that queries an unprepared.
794
795 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
796 * Line Wrap on SQL Token boundaries (on user command)
797 * auto-complete table names in drop down list of table names
798 * Double click on tablename or field name adds to SQL text
799
800 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
801
802 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
803 TVariantArray. Seems to avoid memory corruption in Windows (probably a
804 workaround for a problem in fpc 3.0.4 win64).
805
806 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
807
808 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
809
810 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
811
812 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
813 include remote system name.
814
815 2. TIBExtract: No longer include comment header and COMMIT statement for empty
816 tables when data included in output.
817
818 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
819 and timing information to be written to stdout. This may be used to locate
820 performance bottlenecks.
821
822 4. SQLParser: only call "OnChanging" event handler when value is different.
823
824 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
825
826 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
827 that BindFields is called when the query is next activated. Avoids FieldName
828 not found error.
829
830 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
831 purpose and allows the programmer to define any action they want for Update, Insert
832 or Delete. This may be complex SQL (similar to a Trigger), application specific
833 filtering of updates, or use of statements such as Grant or Revoke instead of
834 normal DML. See User Manual for more information.
835
836 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
837
838 1. TIBEvents: Fix uninitialised variable that could result in lost events.
839
840 2. TIBExtract: Added support for FB3 "USAGE" privilege.
841
842 3. TIBExtract: data formatted as Charset set "octets" is now output using
843 hexadecimal notation.
844
845 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
846 using a simple XML format.
847
848 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
849 grants to these objects.
850
851 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
852 dependency problems restoring complex databases.
853
854 7. TIBXScript: This component has been restructured to allow for the processing of
855 embedded XML in INSERT statements and to support interactive sources in addition
856 to non-interactive data sources such as files.
857
858 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
859
860 9. TIBXScript: ISQL compatiable Set statements are now supported:
861 SET SQL DIALECT
862 SET TERM
863 SET AUTODDL
864 SET BAIL
865 SET ECHO
866 SET COUNT
867 SET STATS
868 SET NAMES <character set>
869
870 10. IBVersion unit added to hold current IBX Version Number information.
871
872 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
873 and domain definitions.
874
875 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
876 fully supported.
877
878 13. TIBExtract: when a database dump includes data, the generator values are now also set.
879
880 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
881
882 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
883
884 See also doc/IBX4LazarusGuide.pdf for important information on
885 upgrading to IBX2.
886
887 1. Size property of TIBStringField is now the width in characters of the field
888 and not the byte length. This applies only to multi-byte character sets such
889 as UTF8. The original approach aligned with TStringField. However, the TStringField
890 code is not recognised as a bug and hence this change to align the behaviour.
891 The TStringField change is expected in fpc 3.2.0.
892
893 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
894 true (default) then Size property value saved in the lfm is ignored. Size is
895 always set from the dynamic information read from the database. It is unclear
896 why anyone would want to override this and set Size to false.
897
898 3. ibxscript: should now handle correctly a Case..End statement within a procedure
899 block.
900
901 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
902 exist when an attempt is made to connect to it (run time only) then an attempt
903 is made to create the database.
904
905 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
906 has been successfully created as a result of a call to CreateDatabase or when
907 creating a database after it was found not to exist.
908
909 6. DBControlGrid: a race condition could result in the wrong row image being
910 written to the cache. This has been avoided by a trip round the message
911 loop before rendering the row image.
912
913 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
914 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
915 known to risk corrupt rendering of row images when the control is first
916 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
917 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
918
919 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
920 a TDateEdit control located on an editor panel.
921
922 9. TIBExtract: brought up-to-date plus many bug fixes.
923
924 10. DBControlGrid: Removed memory leak when updating rows.
925
926 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
927
928 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
929
930 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
931 when target codepage is CP_NONE. This is a workaround for
932 http://bugs.freepascal.org/view.php?id=30622.
933
934 2. DBLog option removed from TIBStatisticalService - not supported by server
935 since Firebird 1.5.
936
937 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
938 similar.
939
940 4. IBCodePage: updated mapping between codepages and character id.
941
942 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
943 Firebird. Character sets with a char width of two are not UTF16.
944
945 6. Strings received from the database are now always transliterated into UTF8
946 regardless of the database character set or connection character set. This
947 is for compatibility with the LCL.

949 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
950
951 1. IBBlob: Defer reading of blob until read method called. This avoids having to
952 read in an entire blob just to get the size of the blob. General performance
953 improvement when opening datasets containing blobs.
954
955 2. Clearing a Blob now sets the corresponding field's modified flag.
956
957 3. IBLookupCombo: When not performing auto-complete, original query sort order
958 is now used.
959
960 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
961 determined.
962
963 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
964
965 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
966 lazarus 1.6.0
967
968 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
969 compilation error.
970
971 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
972
973 1. No character set specified for connection: when a text blob is retrieved, the
974 character set is determined by looking up the native character set using then
975 Firebird API. Otherwise a text mode blob is assumed to have the same character
976 set as the connection.
977
978 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
979 for Login Dialog returing a change to the database path.
980
981 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
982 to be changed from that given in the TIBDatabase/TIBServer component and for the
983 entered value to be saved on a project specific basis (design time only).
984
985 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
986 column fieldname. If they are the same then it is acts as a look up for the KeyValue
987 Otherwise, it sets the column text to the selected ListField Value.
988
989 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
990 column width.
991
992 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
993 and a case insensitive search is requested.
994
995 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
996 or column ListSource.
997
998 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
999 unprepare) when closing and the text has not changed.
1000
1001 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1002 Less likely to cause a cursor re-use error on Windows.
1003
1004 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1005 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1006
1007 11. TIBTreeView: Guard against nil destination on record changed
1008
1009 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1010 string type with the code page set to reflect the returned field encoding after
1011 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1012 earlier versions.
1013
1014 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1015 will now result in transliteration to the code page specified for the Firebird driver
1016 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1017
1018 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1019 is ignored and the lc_ctype value, when the database is opened, is set to align with
1020 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1021 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1022 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1023 the GETACP is used to determine the Windows code page.
1024
1025 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1026 name used as the lc_ctype when the database was opened. Only valid while the
1027 Database is connected.
1028
1029 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1030 id that corresponds to the DefaultCharSetName.
1031
1032 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1033
1034 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1035 path is given and database attach fails due to access permission issues on the
1036 temp directory or security database, then the attach is retried with "localhost:"
1037 prefixing the databasename. This should avoid problems when the database has to
1038 be accessed by a local (e.g. classic) server and libfbembed is used.
1039
1040 2. Windows: revised search order for Firebird DLL:
1041 i. The Firebird Embedded Server in the application Directory.
1042 ii. If the FIREBIRD environment variable is set then the directory this
1043 points to is searched for the FB Client DLL and then then underlying
1044 "bin" directory.
1045 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1046 is used to locate the Firebird installation directory and the underlying
1047 "bin" directory is searched for the FB Client DLL.
1048 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1049 are searched for the FB Client DLL.
1050 v. The PATH Environment variable is used to search for the FB Client DLL.
1051 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1052
1053 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1054 See doc/readme.scriptengine and example applications.
1055
1056 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1057 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1058 See dpc/readme.localdatabase and example applications.
1059
1060 5. IBDynamicGrid: Reordering on column header click should now also work for
1061 dynamic columns.
1062
1063 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1064 between incrementing/decrementing the lock count and signalling the event.
1065
1066 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1067
1068 1.3.2 was never formally released and only made available as beta copies.
1069
1070 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1071
1072 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1073
1074 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1075
1076 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1077 i.e. when it is a calculated field
1078
1079 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1080 This problem was due to a race condition between recalculating row heights and
1081 determining which row was selected by the mouse click. The row height calculation
1082 is now deferred by an extra trip round the message loop allowing the row to
1083 be always calculated on the current grid layout rather than risking it being
1084 calculated on the grid layout after the expanded row has been shrunk.
1085
1086 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1087 Windows.
1088
1089 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1090 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1091 to be determined at runtime. See doc/readme.charactersets.html.
1092
1093 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1094 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1095
1096 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1097 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1098 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1099
1100 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1101 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1102 implies no truncation.
1103
1104 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1105
1106 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1107 (avoids "Not in Edit Mode" error).
1108
1109 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1110
1111 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1112 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1113
1114 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1115
1116 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1117
1118 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1119
1120 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1121
1122 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1123
1124 1. OnCloseUp Event Handler added to TDBLookupProperties
1125
1126 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1127 problem with row size when exception is called.
1128
1129 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1130
1131 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1132 in a TCustomComboBox and ignores return key if in a TCustomMemo
1133
1134 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1135 keyed in i.e. when autocomplete not performed
1136
1137 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1138 console mode applications with all LCL required functions (builtin dialogs and
1139 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1140 not included in your project, IBX should compile and link with a console mode program.
1141 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1142 console mode application or the IDE will automatically assume that your
1143 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1144
1145 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1146 to use the built in dialogs and cursor management. IBDialogs is
1147 included by default if "ibexpress" is in your project source's "uses" clause.
1148 This should be the case for all projects created through the IDE. This is why
1149 you do not want to add the ibexpress package to console mode applications. The
1150 ibexpressconsolemode package has been created to allow console mode programs
1151 to avoid adding LCL dependencies when using IBX, while still having the
1152 unit search paths set up correctly.
1153
1154 Existing users should check to ensure that the "ibexpress" unit is included in
1155 each project's source file (*.lpr).
1156
1157 You may find that in order for the IDE to recognise that ibexpressconsolemode
1158 exists, you have to first open the package in the IDE and then close it. This
1159 adds it to the most recently accessed packages list. To make it permanently
1160 available, add the package name to lazarus' staticpackages.inc file.
1161
1162 Thanks to Julio Jiménez for suggesting support of console mode.
1163
1164 7. SQL Parser can now accept quoted strings that include new lines
1165
1166 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1167 of text on start of edit. This is particularly useful when tabbing to a
1168 column and then inserting text.
1169
1170 9. New Examples provided for IB Services and ISQLMonitor.
1171
1172 10. Fix error when writing to blob streams that recorded only the last buffer
1173 write in the blob stream. In most cases, this did not cause a problem as the
1174 IB Blob Stream is written in a single write. However, with the TDBImage, write
1175 of a graphic type prefix was lost which caused a problem when the image could
1176 not be automatically recognised.
1177
1178 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1179 already open" errors due to random numbers used for the cursor name being identical.
1180
1181 12. IBTable: corrected error that could result in an "Index out of bounds" error
1182 when opening the table and the Primary Key is the last or only column in the
1183 table. Thanks to Rick Hoover for the fix.
1184
1185 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1186 of "UTF-8", and update list of available database character sets. Existing
1187 users should check the current lc_ctype setting in their applications.
1188
1189 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1190
1191 1. Firebird Services: avoid List Index error when opening a service with an
1192 empty Params property.
1193
1194 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1195 Link now set up in Loaded method - avoids occasional failure to apply
1196 SQL markup on initial open.
1197
1198 3. "Employees" example performance improvements when scrolling.
1199
1200 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1201 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1202 random image cached).
1203
1204 5. DBControlGrid: Should now react to changes in panel height at run time.
1205
1206 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1207 even when further rows exist.
1208
1209 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1210 always be derived from panel height and setting this property can cause confusion.
1211 Note for existing projects: to avoid a missing property error at run time,
1212 each form using the DBControlGrid must be opened, updated and saved in the IDE
1213 in order to remove the property value from the lfm.
1214
1215
1216 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1217
1218 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1219 call Prepare before setting parameter values.
1220
1221 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1222
1223 3. Code tidyup and more robust handling of dsql information result vector.
1224
1225 4. Support for centralised handling of transaction status changes. TIBTransaction
1226 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1227 and "AfterExecQuery". The first three are called after the same event is called
1228 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1229 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1230 enable monitoring of transaction status changes for a given transaction to be
1231 handled in a single place. For example, when a change to the dataset occurs
1232 an indicator can be set that shows the user that in order to save changes,
1233 the transaction should be committed. Rather than doing this per dataset, this
1234 can now be done per transaction.
1235
1236 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1237 the dataset is scrolled. However, any changes to the current row are, by default,
1238 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1239 have a new property "DataSetCloseAction" that adds automatic posting of changes
1240 on dataset close. If this property is set to dcDiscardChanges (default) then the
1241 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1242 then IBX will attempt to post any unsaved changes before the dataset is closed
1243 (and after the BeforeClose event handler is called). The exception is when the
1244 dataset is being closed as a result of a transaction rollback. In this case,
1245 no action is taken and any unsaved changes are discarded. This avoids both
1246 unnecessary overhead and the risk that a validation error may occur in the Post
1247 raising an exception and thereby preventing a rollback.
1248
1249 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1250 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1251 width. Display Widths are now corrected by dividing by the max byte width per character.
1252 For UTF8 character sets, the byte width is four and hence the Display Width will be
1253 the byte width divided by 4. The byte width of each character set is determined
1254 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1255 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1256
1257 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1258
1259 8. IBLookupComboEditBox: List should now always be restored to full list when the
1260 control loses focus. Default Key press default interval reduced to 200ms.
1261
1262 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1263 when dataset rows are less than visible rows.
1264
1265 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1266 does not exist or DataSet is empty. More responsive on dataset open. New event
1267 OnRestorePosition. Column sort disabled if no header row.
1268
1269 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1270 while dataset state is dsInsert. Avoids posting errors.
1271
1272 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1273 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1274
1275 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1276
1277 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1278 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1279 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1280 always "posts" the current record regardless or whether or not it may be more appropriate
1281 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1282 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1283 as the first action of the "Post" method and allows the handler to convert the Post
1284 into a Cancel if that is the appropriate action on moving to a different row. This is
1285 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1286 raised here, but it may still be more appropriate to validate a post and signal
1287 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1288
1289 15. On Unix derived systems, the Firebird library name can now be given as a colon
1290 separated list. Each library name on the list is tried in turn, in left to right
1291 order with the first found being used as the firebird library. By default, on Linux,
1292 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1293 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1294
1295 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1296 then it will still attempt to access the database via the Firebird Server and will
1297 require a username and password. If only the pathname is given, then the username
1298 and password should be omitted and the unix file permissions are used to grant
1299 access.
1300
1301 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1302
1303 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1304 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1305 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1306 corresponds to a row of the linked DataSource. Any data aware control on the
1307 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1308
1309 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1310 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1311 takes place during database access. This may be useful when there are performance issues with
1312 the change of cursor. Setting the property to false suppresses the change of cursor.
1313
1314 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1315 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1316 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1317 making all changes permanent immediately rather than when the transaction is explicitly
1318 committed.
1319
1320 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1321 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1322
1323 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1324
1325 Development version only.
1326
1327 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1328
1329 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1330 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1331 "Where" and "Having" clauses to implement user specified filters of arbitrary
1332 complexity.
1333
1334 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1335 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1336 These are:
1337
1338 - TIBLookupComboEditBox
1339 - TIBDynamicGrid
1340 - TIBTreeview
1341
1342 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1343 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1344 to revise the available list and restrict it to items that are prefixed by the
1345 typed text (either case sensitive or case insensitive). Autoinsert allows a
1346 newly typed entry to be added to the list dataset and included in the available
1347 list items.
1348
1349 TIBDynamicGrid is a TDBGrid descendent that provides for:
1350 - automatic resizing of selected columns to fill the available row length
1351 - automatic positioning and sizing of a "totals" control, typically at the
1352 column footer, on a per column basis.
1353 - DataSet resorting on header row click, sorting the dataset by the selected column.
1354 A second click on the same header cell reversed the sort order.
1355 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1356 is automatically expanded and a panel superimposed on it. The panel can have any
1357 number of child controls, typically data aware controls with the same datasource
1358 as the grid allowing for editing of additional fields and more complex editors.
1359 - Reselection of the same row following resorting.
1360 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1361 Its properties are specified on a per column basis and allows for one or more
1362 columns to have their values selected from a list provided by a dataset.
1363 Autocomplete and autoinsert are also available. The existing picklist editor
1364 is unaffected by the extension.
1365
1366 TIBTreeView is a data aware TCustomTreeView.

1368 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1369 zero scale will no longer return an error. An Int64 will be returned instead.
1370
1371 4. TIBTransaction now has events for Before and After Transaction End and a new function
1372 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1373
1374 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1375 repeated multiple times.
1376
1377 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1378 check used to get in the way of using Stored Procedures, and "Update or Insert"
1379 statements.
1380
1381 7. Insert, Modify and Delete property Editors now support Query Generation from
1382 Stored Procedures.
1383
1384 8. Three new examples illustrate the use of the new IB Controls

1387 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1388
1389 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1390 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1391 Gabor Boros for reporting this problem and for testing the improvements).
1392
1393 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1394 See readme.field+param.names in the doc folder.
1395
1396 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1397 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1398
1399 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1400
1401 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1402 actions.
1403
1404 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1405 thanks to Yuriy Kopnin for pointing this out).
1406
1407 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1408
1409 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1410 for both fields and parameter setting.
1411
1412 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1413 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1414
1415 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1416 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1417
1418 11. TIBTable now has a property editor for "MasterFields"
1419
1420 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1421 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1422
1423 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1424 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1425

1427 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1428
1429 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1430
1431 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1432
1433 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1434 it is null. This allows for alternative user defined setting of the generator
1435
1436 Many thanks to Julio Jiménez for this fix
1437
1438 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1439 and suggests that the user may have forgotten to install it.
1440
1441 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1442
1443 1. Conditional compilation used to limit registration of TIntegerField to
1444 Lazarus versions less than 1.1
1445
1446 2. When a database connection is created, character set is now by default set
1447 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1448 1250 to 1254.
1449
1450
1451 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1452
1453 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1454
1455
1456 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1457
1458 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1459 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1460
1461 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1462 package is changed to do this (which it should do).
1463
1464 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1465
1466 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1467
1468 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1469
1470 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1471
1472 4. Property editors should now correctly resize.
1473
1474 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1475 (restored original functionality)
1476
1477 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1478 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
