1 IBX Change Log version (2.3-0) Fri, 16 Mar 2018 11:07:39 +0000
2
3 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 all previous copies of the IBX source code tree before installing this release.
5
6 The IBX packages used by most users have not changed, with one exception. The
7 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 to use the IBServices unit in your applications, please add the iblegacyServices
9 to the list of dependencies. To do this, open the Project Inspector and select
10 Add->New Requirement and select "ibLegacyServices" from the list of available
11 packages.
12
13 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 the IBServices unit providing what is intended to be a clearer and easier to
15 use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 more information and the guide to "Firebird Service Management Using IBX".
17 As indicated above, the legacy services components are still available and
18 provided in a separate package. There is no need to update working applications
19 using the older versions except for an additional package dependency.
20
21 2. The IBX packages and source code tree have been re-organised in an attempt to
22 finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 not affect existing users. Section 2.3 of the IBX User Guide describes the
24 new set of IBX packages.
25
26 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 updated to use the new Services API components.
28
29 4. The iblocal package has been updated to use the new Services API components.
30
31 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 TIBXSecurityService. It had been wrongly classified in the previous version
33 as a per database configuration item. It is global to a server and hence
34 correctly positioned as part of the Security Package. In the DBAdmin example,
35 the setting has moved to the mappings page.
36
37 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 are ignored.
39
40 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 closed before the database is dropped. Before and After Disconnect event handlers
42 are also fired.
43
44 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 is started and not just the first time.
46
47 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 depenendency with comp type.
49
50 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51
52 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 then this is recognised and not ignored.
54
55 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59
60 GetRowsAffected returns the affected row counts from the last insert/update/delete
61 if EnableStatistics = true then GetPerfStatistics returns the current stats
62 counters for the select query. Note: stats accumulate after each fetch from
63 the database. To get total query cost after open, call the "Last" method
64 and then GetPerfStatistics.
65
66 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67
68 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 in parenthesises.
70
71 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 SQL identifiers are always delimited by double quotes. If false, then they are
73 only delimited if the identifier is a reserved word, contains lower case or special
74 characters. Set this property to true to retain previous behaviour.
75
76 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78
79 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 property MasterDetailDelay: integer {defaults to zero}
81
82 When non-zero and the dataset is a detail table referencing a master table
83 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 then a synchronisation delay is added (in milliseconds) between the master
85 row changing and the detail dataset being re-opened. If the master dataset
86 is scrolled before the delay expires then the delay is reset. This can be used
87 to avoid performance overheads when scrolling through a large master dataset.
88
89 Note: uses fptimer and hence requires a thread manager. Under Linux the
90 chreads unit must be included in your project. TTimer is not used in order
91 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92
93 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 with Extract Option eoDatabase.
95
96 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 When a deLaoutChanged event is reported on the ListSource dataset, the
98 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 relationship with the control's datasource (master).
100
101 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
102
103 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 RELEASE.
106
107 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
108
109 1. IBExtract: Identity columns - add additional check for null column for generator name.
110
111 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
112 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
113 information). However, this is also a very useful mechanism for returning updated computed by
114 column values. Values returned as a result of executing an Insert or Update statement
115 replace existing values in the current row for each corresponding column.
116
117 Previously, if a dataset's select query included read only (computed by) fields then
118 an automatic row refresh was performed after an insert or update query had been processed,
119 irrespective of the setting of the "ForcedUpdates" property. This has changed such
120 that an automatic refresh is no longer performed if an insert or update query contains
121 a returning clause that updates one or more fields on the current row. A full row
122 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
123 field values and the select query contains read only fields. Use of Insert/update
124 returning should be significantly more efficient than executing a refresh query.
125
126 This behaviour change is intended to be backwards compatible and there should be no need to change
127 existing programs, other than to improve performance by using the new capability.
128
129 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
130 they are called when the dataset row is being deleted, there is no value in
131 updating the current record from the query result. Instead, a new event handler
132 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
133 an OnDeleteReturning event handler is provided then it is called with the IResults returned
134 by the query. The event handler can then interrogate the query results and
135 perform whatever action is necessary. For example to confirm, to the user,
136 the deletion of a row with the returned values.
137
138 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
139 any Computed By or Identity Columns. The IBTables example has been updated to
140 illustrate the computation of the employee Full Name on update.
141
142 5. TIBTable: The GeneratorField property is now published.
143
144 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
145 When InsertSQL is generated, the Identity columns are not included in the list of values to
146 be inserted. A RETURNING clause is added to the insert statement to return the value of
147 each Identity column after the insert is executed.
148
149 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
150 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
151 Insert..Returning clause.
152
153 8. TIBGenerator: small performance improvement by not preparing query each time
154 a new value is generated.
155
156 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
157
158 10. Property editors will now sync table name to a System Table when "Include System
159 Tables" is selected and the query is for a System Table.
160
161 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
162 values are no longer converted to milliseconds from TDateTime and then back again
163 to TDateTime (the conversion to milliseconds is the default TDataset approach).
164
165 12. Property Editors handling of Stored Procedures.
166 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
167 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
168 query).
169 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
170
171 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
172 can be used to select a package. If non-empty, the stored procedure name is
173 expected to be a stored procedure defined in the specified package and the
174 generated SQL will be as required for a stored procedure located in a package.
175
176 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
177 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
178 which a stored procedure can be selected. With no package name selected, non-package
179 stored procedures are listed.
180
181 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182 for password on reconnect.
183
184 16. TIBDatabase: use IAttachment for connection default character set id, code page
185 and character set name.
186
187 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
188 DB info lookups"
189
190 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
191
192 19. Add a property Editor for TIBUpdate.RefreshSQL.
193
194 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
195 parameters. This stops an exception being raised when the field cannot be
196 located in the record buffer.
197
198 21. Property Editors now automatically include System Tables when opened and when the query table
199 is a System Table.
200
201 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
202 This avoids errors due to a stale SQRB or SRB being used for the next query.
203
204 23. IBServices: Service attach parameters now include "expected_db". This is used to
205 add the SPB item isc_spb_expected_db. This names a database using
206 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
207 database. examples/services re-written to illustrate use of "expected_db".
208
209 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
210 This avoids truncated backups when the server returns a timeout (busy) response.
211
212 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
213
214 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
215 databasenames. These are respectively expanded to the local system's temp directory
216 (including trailing delimiter) or to a prescribed data directory (including
217 trailing delimiter). Under Unix systems the data directory is a hidden directory
218 in the user's home directory. The hidden directory name is either the string returned
219 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220 Under Windows, the directory is the same as the Data Directory as decribed
221 above but instead prefixed by the User's application data path. These may be
222 used to improve application portability for Personal Databases.
223
224 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
225 this has not worked for a long time and is not useful either. FieldDefs should be
226 managed using the Fields Editor as with any other dataset. To access the fields
227 editor for a TIBTable component, double click on the component. The fields editor
228 is then displayed.
229
230 28. TIBDatabaseInfo: new properties/function
231 * DateDBCreated (returns date/time database created)
232 * TransactionCount (returns no. of active transactions)
233 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
234 * PagesFree (Firebird 3 or later)
235 * PagesUsed (Firebird 3 or later)
236 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
237 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
238
239 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
240
241 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
242
243 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
244 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
245
246 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
247 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
248 firing during backup and restore.
249
250 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
251 for verbose output using the new property "StatisticsRequested".
252 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
253
254 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
255
256 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
257 palette. This uses the online validation feature added in Firebird 2.5. The
258 services's properties enable inclusion/exclusion of tables and indexes using
259 regular expressions. See.
260 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
261
262 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
263 option on a database.
264
265 37. TIBCustomService: Assign method implemented to allow copying of service login
266 context between service API components. "Detach" method now only detaches
267 service when last reference to the service interface detaches. Tidy up of
268 code for SetActive and Attach methods including password hiding.
269
270 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
271 and used to determine the auth method and protocol used for the connection.
272
273 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
274 a Create Database Statement generated by IBX.
275
276 40. All IBServices now have an additional published property "PortNo". This may
277 be set to a non-standard port number when necessary. If zero then the default
278 port number is used.
279
280 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
281 and not just the mouse.
282
283 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
284
285 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
286 image index and selected image index for each node to be set from a database field.
287
288 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
289 then database schema includes grants to all users. If not present then the
290 only user grants included are those to User PUBLIC.
291
292 45. TIBTreeView: performance improvement. When expanding include both expanded node
293 and child nodes in dataset.
294
295
296 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
297
298 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
299 changes.
300
301 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
302 Bug could result in truncated multi-byte character set values.
303
304 3. Changes consequential on moving fbintf character set utility functions from
305 IFirebirdAPI to IAttachment.
306
307 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
308
309 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
310 results in autocomplete ignoring prefix text.
311
312 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
313 entering a new name into the text box.
314
315 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
316 Firebird rather than recomputing it.
317
318 8. Property Editor positioning tidy up: All IBX Property editors should now be
319 screen centre. Previously some were "poDesigned" which may be inappropriate
320 for multi monitor desktops.
321
322 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
323
324 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
325 a transaction and always reset the object.
326
327 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
328
329 13. TIBXScript: Allow for override of database filename in Create Database statements.
330
331 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
332 to a gbak format archive.
333
334 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
335
336 16. IBLocaldb: Drop database if error creating an empty database.
337
338 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
339 unless selected node not in current dataset.
340
341 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
342 to TIBCustomService, and IBlocalDB code tidy up.
343
344 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
345 behaviour due to uninitialised variable.
346
347 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
348 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
349
350 21. IBSQL: When Database changed ensure that all resources are freed.
351
352 22. IBCustomDataset: When database changed ensure that queries an unprepared.
353
354 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
355 * Line Wrap on SQL Token boundaries (on user command)
356 * auto-complete table names in drop down list of table names
357 * Double click on tablename or field name adds to SQL text
358
359 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
360
361 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
362 TVariantArray. Seems to avoid memory corruption in Windows (probably a
363 workaround for a problem in fpc 3.0.4 win64).
364
365 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
366
367 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
368
369 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
370
371 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
372 include remote system name.
373
374 2. TIBExtract: No longer include comment header and COMMIT statement for empty
375 tables when data included in output.
376
377 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
378 and timing information to be written to stdout. This may be used to locate
379 performance bottlenecks.
380
381 4. SQLParser: only call "OnChanging" event handler when value is different.
382
383 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
384
385 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
386 that BindFields is called when the query is next activated. Avoids FieldName
387 not found error.
388
389 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
390 purpose and allows the programmer to define any action they want for Update, Insert
391 or Delete. This may be complex SQL (similar to a Trigger), application specific
392 filtering of updates, or use of statements such as Grant or Revoke instead of
393 normal DML. See User Manual for more information.
394
395 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
396
397 1. TIBEvents: Fix uninitialised variable that could result in lost events.
398
399 2. TIBExtract: Added support for FB3 "USAGE" privilege.
400
401 3. TIBExtract: data formatted as Charset set "octets" is now output using
402 hexadecimal notation.
403
404 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
405 using a simple XML format.
406
407 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
408 grants to these objects.
409
410 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
411 dependency problems restoring complex databases.
412
413 7. TIBXScript: This component has been restructured to allow for the processing of
414 embedded XML in INSERT statements and to support interactive sources in addition
415 to non-interactive data sources such as files.
416
417 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
418
419 9. TIBXScript: ISQL compatiable Set statements are now supported:
420 SET SQL DIALECT
421 SET TERM
422 SET AUTODDL
423 SET BAIL
424 SET ECHO
425 SET COUNT
426 SET STATS
427 SET NAMES <character set>
428
429 10. IBVersion unit added to hold current IBX Version Number information.
430
431 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
432 and domain definitions.
433
434 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
435 fully supported.
436
437 13. TIBExtract: when a database dump includes data, the generator values are now also set.
438
439 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
440
441 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
442
443 See also doc/IBX4LazarusGuide.pdf for important information on
444 upgrading to IBX2.
445
446 1. Size property of TIBStringField is now the width in characters of the field
447 and not the byte length. This applies only to multi-byte character sets such
448 as UTF8. The original approach aligned with TStringField. However, the TStringField
449 code is not recognised as a bug and hence this change to align the behaviour.
450 The TStringField change is expected in fpc 3.2.0.
451
452 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
453 true (default) then Size property value saved in the lfm is ignored. Size is
454 always set from the dynamic information read from the database. It is unclear
455 why anyone would want to override this and set Size to false.
456
457 3. ibxscript: should now handle correctly a Case..End statement within a procedure
458 block.
459
460 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
461 exist when an attempt is made to connect to it (run time only) then an attempt
462 is made to create the database.
463
464 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
465 has been successfully created as a result of a call to CreateDatabase or when
466 creating a database after it was found not to exist.
467
468 6. DBControlGrid: a race condition could result in the wrong row image being
469 written to the cache. This has been avoided by a trip round the message
470 loop before rendering the row image.
471
472 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
473 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
474 known to risk corrupt rendering of row images when the control is first
475 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
476 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
477
478 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
479 a TDateEdit control located on an editor panel.
480
481 9. TIBExtract: brought up-to-date plus many bug fixes.
482
483 10. DBControlGrid: Removed memory leak when updating rows.
484
485 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
486
487 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
488
489 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
490 when target codepage is CP_NONE. This is a workaround for
491 http://bugs.freepascal.org/view.php?id=30622.
492
493 2. DBLog option removed from TIBStatisticalService - not supported by server
494 since Firebird 1.5.
495
496 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
497 similar.
498
499 4. IBCodePage: updated mapping between codepages and character id.
500
501 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
502 Firebird. Character sets with a char width of two are not UTF16.
503
504 6. Strings received from the database are now always transliterated into UTF8
505 regardless of the database character set or connection character set. This
506 is for compatibility with the LCL.
507
508 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
509
510 1. IBBlob: Defer reading of blob until read method called. This avoids having to
511 read in an entire blob just to get the size of the blob. General performance
512 improvement when opening datasets containing blobs.
513
514 2. Clearing a Blob now sets the corresponding field's modified flag.
515
516 3. IBLookupCombo: When not performing auto-complete, original query sort order
517 is now used.
518
519 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
520 determined.
521
522 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
523
524 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
525 lazarus 1.6.0
526
527 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
528 compilation error.
529
530 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
531
532 1. No character set specified for connection: when a text blob is retrieved, the
533 character set is determined by looking up the native character set using then
534 Firebird API. Otherwise a text mode blob is assumed to have the same character
535 set as the connection.
536
537 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
538 for Login Dialog returing a change to the database path.
539
540 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
541 to be changed from that given in the TIBDatabase/TIBServer component and for the
542 entered value to be saved on a project specific basis (design time only).
543
544 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
545 column fieldname. If they are the same then it is acts as a look up for the KeyValue
546 Otherwise, it sets the column text to the selected ListField Value.
547
548 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
549 column width.
550
551 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
552 and a case insensitive search is requested.
553
554 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
555 or column ListSource.
556
557 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
558 unprepare) when closing and the text has not changed.
559
560 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
561 Less likely to cause a cursor re-use error on Windows.
562
563 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
564 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
565
566 11. TIBTreeView: Guard against nil destination on record changed
567
568 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
569 string type with the code page set to reflect the returned field encoding after
570 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
571 earlier versions.
572
573 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
574 will now result in transliteration to the code page specified for the Firebird driver
575 if the assigned string has a different code page. FPC 3.0.0 onwards only.
576
577 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
578 is ignored and the lc_ctype value, when the database is opened, is set to align with
579 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
580 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
581 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
582 the GETACP is used to determine the Windows code page.
583
584 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
585 name used as the lc_ctype when the database was opened. Only valid while the
586 Database is connected.
587
588 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
589 id that corresponds to the DefaultCharSetName.
590
591 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
592
593 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
594 path is given and database attach fails due to access permission issues on the
595 temp directory or security database, then the attach is retried with "localhost:"
596 prefixing the databasename. This should avoid problems when the database has to
597 be accessed by a local (e.g. classic) server and libfbembed is used.
598
599 2. Windows: revised search order for Firebird DLL:
600 i. The Firebird Embedded Server in the application Directory.
601 ii. If the FIREBIRD environment variable is set then the directory this
602 points to is searched for the FB Client DLL and then then underlying
603 "bin" directory.
604 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
605 is used to locate the Firebird installation directory and the underlying
606 "bin" directory is searched for the FB Client DLL.
607 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
608 are searched for the FB Client DLL.
609 v. The PATH Environment variable is used to search for the FB Client DLL.
610 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
611
612 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
613 See doc/readme.scriptengine and example applications.
614
615 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
616 simplify the use of the embedded firebird server on both Linux and Windows platforms.
617 See dpc/readme.localdatabase and example applications.
618
619 5. IBDynamicGrid: Reordering on column header click should now also work for
620 dynamic columns.
621
622 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
623 between incrementing/decrementing the lock count and signalling the event.
624
625 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
626
627 1.3.2 was never formally released and only made available as beta copies.
628
629 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
630
631 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
632
633 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
634
635 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
636 i.e. when it is a calculated field
637
638 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
639 This problem was due to a race condition between recalculating row heights and
640 determining which row was selected by the mouse click. The row height calculation
641 is now deferred by an extra trip round the message loop allowing the row to
642 be always calculated on the current grid layout rather than risking it being
643 calculated on the grid layout after the expanded row has been shrunk.
644
645 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
646 Windows.
647
648 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
649 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
650 to be determined at runtime. See doc/readme.charactersets.html.
651
652 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
653 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
654
655 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
656 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
657 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
658
659 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
660 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
661 implies no truncation.
662
663 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
664
665 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
666 (avoids "Not in Edit Mode" error).
667
668 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
669
670 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
671 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
672
673 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
674
675 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
676
677 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
678
679 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
680
681 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
682
683 1. OnCloseUp Event Handler added to TDBLookupProperties
684
685 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
686 problem with row size when exception is called.
687
688 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
689
690 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
691 in a TCustomComboBox and ignores return key if in a TCustomMemo
692
693 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
694 keyed in i.e. when autocomplete not performed
695
696 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
697 console mode applications with all LCL required functions (builtin dialogs and
698 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
699 not included in your project, IBX should compile and link with a console mode program.
700 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
701 console mode application or the IDE will automatically assume that your
702 application is GUI based. Instead, you should include the ibexpressconsolemode package.
703
704 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
705 to use the built in dialogs and cursor management. IBDialogs is
706 included by default if "ibexpress" is in your project source's "uses" clause.
707 This should be the case for all projects created through the IDE. This is why
708 you do not want to add the ibexpress package to console mode applications. The
709 ibexpressconsolemode package has been created to allow console mode programs
710 to avoid adding LCL dependencies when using IBX, while still having the
711 unit search paths set up correctly.
712
713 Existing users should check to ensure that the "ibexpress" unit is included in
714 each project's source file (*.lpr).
715
716 You may find that in order for the IDE to recognise that ibexpressconsolemode
717 exists, you have to first open the package in the IDE and then close it. This
718 adds it to the most recently accessed packages list. To make it permanently
719 available, add the package name to lazarus' staticpackages.inc file.
720
721 Thanks to Julio Jiménez for suggesting support of console mode.
722
723 7. SQL Parser can now accept quoted strings that include new lines
724
725 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
726 of text on start of edit. This is particularly useful when tabbing to a
727 column and then inserting text.
728
729 9. New Examples provided for IB Services and ISQLMonitor.
730
731 10. Fix error when writing to blob streams that recorded only the last buffer
732 write in the blob stream. In most cases, this did not cause a problem as the
733 IB Blob Stream is written in a single write. However, with the TDBImage, write
734 of a graphic type prefix was lost which caused a problem when the image could
735 not be automatically recognised.
736
737 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
738 already open" errors due to random numbers used for the cursor name being identical.
739
740 12. IBTable: corrected error that could result in an "Index out of bounds" error
741 when opening the table and the Primary Key is the last or only column in the
742 table. Thanks to Rick Hoover for the fix.
743
744 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
745 of "UTF-8", and update list of available database character sets. Existing
746 users should check the current lc_ctype setting in their applications.
747
748 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
749
750 1. Firebird Services: avoid List Index error when opening a service with an
751 empty Params property.
752
753 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
754 Link now set up in Loaded method - avoids occasional failure to apply
755 SQL markup on initial open.
756
757 3. "Employees" example performance improvements when scrolling.
758
759 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
760 TFrame. Force recaching of selected frame to avoid GTK race (results in a
761 random image cached).
762
763 5. DBControlGrid: Should now react to changes in panel height at run time.
764
765 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
766 even when further rows exist.
767
768 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
769 always be derived from panel height and setting this property can cause confusion.
770 Note for existing projects: to avoid a missing property error at run time,
771 each form using the DBControlGrid must be opened, updated and saved in the IDE
772 in order to remove the property value from the lfm.
773
774
775 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
776
777 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
778 call Prepare before setting parameter values.
779
780 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
781
782 3. Code tidyup and more robust handling of dsql information result vector.
783
784 4. Support for centralised handling of transaction status changes. TIBTransaction
785 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
786 and "AfterExecQuery". The first three are called after the same event is called
787 for an IBCustomDataSet descendent using the Transaction. The fourth is called
788 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
789 enable monitoring of transaction status changes for a given transaction to be
790 handled in a single place. For example, when a change to the dataset occurs
791 an indicator can be set that shows the user that in order to save changes,
792 the transaction should be committed. Rather than doing this per dataset, this
793 can now be done per transaction.
794
795 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
796 the dataset is scrolled. However, any changes to the current row are, by default,
797 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
798 have a new property "DataSetCloseAction" that adds automatic posting of changes
799 on dataset close. If this property is set to dcDiscardChanges (default) then the
800 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
801 then IBX will attempt to post any unsaved changes before the dataset is closed
802 (and after the BeforeClose event handler is called). The exception is when the
803 dataset is being closed as a result of a transaction rollback. In this case,
804 no action is taken and any unsaved changes are discarded. This avoids both
805 unnecessary overhead and the risk that a validation error may occur in the Post
806 raising an exception and thereby preventing a rollback.
807
808 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
809 In earlier versions, the Display Width was set to the maximum byte width rather than the character
810 width. Display Widths are now corrected by dividing by the max byte width per character.
811 For UTF8 character sets, the byte width is four and hence the Display Width will be
812 the byte width divided by 4. The byte width of each character set is determined
813 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
814 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
815
816 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
817
818 8. IBLookupComboEditBox: List should now always be restored to full list when the
819 control loses focus. Default Key press default interval reduced to 200ms.
820
821 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
822 when dataset rows are less than visible rows.
823
824 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
825 does not exist or DataSet is empty. More responsive on dataset open. New event
826 OnRestorePosition. Column sort disabled if no header row.
827
828 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
829 while dataset state is dsInsert. Avoids posting errors.
830
831 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
832 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
833
834 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
835
836 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
837 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
838 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
839 always "posts" the current record regardless or whether or not it may be more appropriate
840 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
841 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
842 as the first action of the "Post" method and allows the handler to convert the Post
843 into a Cancel if that is the appropriate action on moving to a different row. This is
844 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
845 raised here, but it may still be more appropriate to validate a post and signal
846 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
847
848 15. On Unix derived systems, the Firebird library name can now be given as a colon
849 separated list. Each library name on the list is tried in turn, in left to right
850 order with the first found being used as the firebird library. By default, on Linux,
851 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
852 overidden by the FBLIB environment variable or the OnGetLibraryName function.
853
854 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
855 then it will still attempt to access the database via the Firebird Server and will
856 require a username and password. If only the pathname is given, then the username
857 and password should be omitted and the unix file permissions are used to grant
858 access.
859
860 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
861
862 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
863 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
864 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
865 corresponds to a row of the linked DataSource. Any data aware control on the
866 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
867
868 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
869 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
870 takes place during database access. This may be useful when there are performance issues with
871 the change of cursor. Setting the property to false suppresses the change of cursor.
872
873 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
874 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
875 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
876 making all changes permanent immediately rather than when the transaction is explicitly
877 committed.
878
879 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
880 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
881
882 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
883
884 Development version only.
885
886 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
887
888 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
889 This is typically used during an "OnBeforeOpen" event handler to manipulate the
890 "Where" and "Having" clauses to implement user specified filters of arbitrary
891 complexity.
892
893 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
894 three new data aware controls dependent on IBX and which make use of the SQL Parser.
895 These are:
896
897 - TIBLookupComboEditBox
898 - TIBDynamicGrid
899 - TIBTreeview
900
901 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
902 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
903 to revise the available list and restrict it to items that are prefixed by the
904 typed text (either case sensitive or case insensitive). Autoinsert allows a
905 newly typed entry to be added to the list dataset and included in the available
906 list items.
907
908 TIBDynamicGrid is a TDBGrid descendent that provides for:
909 - automatic resizing of selected columns to fill the available row length
910 - automatic positioning and sizing of a "totals" control, typically at the
911 column footer, on a per column basis.
912 - DataSet resorting on header row click, sorting the dataset by the selected column.
913 A second click on the same header cell reversed the sort order.
914 - Support for a "Panel Editor". That is on clicking the indicator column, the row
915 is automatically expanded and a panel superimposed on it. The panel can have any
916 number of child controls, typically data aware controls with the same datasource
917 as the grid allowing for editing of additional fields and more complex editors.
918 - Reselection of the same row following resorting.
919 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
920 Its properties are specified on a per column basis and allows for one or more
921 columns to have their values selected from a list provided by a dataset.
922 Autocomplete and autoinsert are also available. The existing picklist editor
923 is unaffected by the extension.
924
925 TIBTreeView is a data aware TCustomTreeView.
926
927 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
928 zero scale will no longer return an error. An Int64 will be returned instead.
929
930 4. TIBTransaction now has events for Before and After Transaction End and a new function
931 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
932
933 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
934 repeated multiple times.
935
936 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
937 check used to get in the way of using Stored Procedures, and "Update or Insert"
938 statements.
939
940 7. Insert, Modify and Delete property Editors now support Query Generation from
941 Stored Procedures.
942
943 8. Three new examples illustrate the use of the new IB Controls

946 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
947
948 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
949 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
950 Gabor Boros for reporting this problem and for testing the improvements).
951
952 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
953 See readme.field+param.names in the doc folder.
954
955 3. IBX SQL Editors will now automatically add double quotes around column names when the database
956 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
957
958 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
959
960 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
961 actions.
962
963 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
964 thanks to Yuriy Kopnin for pointing this out).
965
966 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
967
968 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
969 for both fields and parameter setting.
970
971 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
972 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
973
974 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
975 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
976
977 11. TIBTable now has a property editor for "MasterFields"
978
979 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
980 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
981
982 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
983 of settings is unrecognised. Selecting this radio button has no effect on the settings.

989
990 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
991
992 1. In a TIBCustomDataset descendent, a generator now only sets the value when
993 it is null. This allows for alternative user defined setting of the generator
994
995 Many thanks to Julio Jiménez for this fix
996
997 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
998 and suggests that the user may have forgotten to install it.
999
1000 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1001
1002 1. Conditional compilation used to limit registration of TIntegerField to
1003 Lazarus versions less than 1.1
1004
1005 2. When a database connection is created, character set is now by default set
1006 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1007 1250 to 1254.
1008

1013
1014
1015 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1016
1017 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1018 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1019
1020 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1021 package is changed to do this (which it should do).
1022
1023 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1024
1025 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1026
1027 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1028
1029 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1030
1031 4. Property editors should now correctly resize.
1032
1033 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1034 (restored original functionality)
1035
1036 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1037 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
