1 IBX Change Log version (2.3-0) Mon, 19 Mar 2018 09:45:35 +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 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102
103 20. Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 stubs. Pedantic fix really, as procedures output in dependency order anyway.
105
106 21. TIBExtact: Package Headers and Package Bodies are now included in the extracted
107 DDL (Firebird 3 and later only).
108
109 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
110
111 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
112 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
113 RELEASE.
114
115 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
116
117 1. IBExtract: Identity columns - add additional check for null column for generator name.
118
119 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
120 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
121 information). However, this is also a very useful mechanism for returning updated computed by
122 column values. Values returned as a result of executing an Insert or Update statement
123 replace existing values in the current row for each corresponding column.
124
125 Previously, if a dataset's select query included read only (computed by) fields then
126 an automatic row refresh was performed after an insert or update query had been processed,
127 irrespective of the setting of the "ForcedUpdates" property. This has changed such
128 that an automatic refresh is no longer performed if an insert or update query contains
129 a returning clause that updates one or more fields on the current row. A full row
130 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
131 field values and the select query contains read only fields. Use of Insert/update
132 returning should be significantly more efficient than executing a refresh query.
133
134 This behaviour change is intended to be backwards compatible and there should be no need to change
135 existing programs, other than to improve performance by using the new capability.
136
137 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
138 they are called when the dataset row is being deleted, there is no value in
139 updating the current record from the query result. Instead, a new event handler
140 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
141 an OnDeleteReturning event handler is provided then it is called with the IResults returned
142 by the query. The event handler can then interrogate the query results and
143 perform whatever action is necessary. For example to confirm, to the user,
144 the deletion of a row with the returned values.
145
146 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
147 any Computed By or Identity Columns. The IBTables example has been updated to
148 illustrate the computation of the employee Full Name on update.
149
150 5. TIBTable: The GeneratorField property is now published.
151
152 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
153 When InsertSQL is generated, the Identity columns are not included in the list of values to
154 be inserted. A RETURNING clause is added to the insert statement to return the value of
155 each Identity column after the insert is executed.
156
157 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
158 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
159 Insert..Returning clause.
160
161 8. TIBGenerator: small performance improvement by not preparing query each time
162 a new value is generated.
163
164 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
165
166 10. Property editors will now sync table name to a System Table when "Include System
167 Tables" is selected and the query is for a System Table.
168
169 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
170 values are no longer converted to milliseconds from TDateTime and then back again
171 to TDateTime (the conversion to milliseconds is the default TDataset approach).
172
173 12. Property Editors handling of Stored Procedures.
174 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
175 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
176 query).
177 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
178
179 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
180 can be used to select a package. If non-empty, the stored procedure name is
181 expected to be a stored procedure defined in the specified package and the
182 generated SQL will be as required for a stored procedure located in a package.
183
184 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
185 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
186 which a stored procedure can be selected. With no package name selected, non-package
187 stored procedures are listed.
188
189 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
190 for password on reconnect.
191
192 16. TIBDatabase: use IAttachment for connection default character set id, code page
193 and character set name.
194
195 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
196 DB info lookups"
197
198 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
199
200 19. Add a property Editor for TIBUpdate.RefreshSQL.
201
202 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
203 parameters. This stops an exception being raised when the field cannot be
204 located in the record buffer.
205
206 21. Property Editors now automatically include System Tables when opened and when the query table
207 is a System Table.
208
209 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
210 This avoids errors due to a stale SQRB or SRB being used for the next query.
211
212 23. IBServices: Service attach parameters now include "expected_db". This is used to
213 add the SPB item isc_spb_expected_db. This names a database using
214 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
215 database. examples/services re-written to illustrate use of "expected_db".
216
217 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
218 This avoids truncated backups when the server returns a timeout (busy) response.
219
220 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
221
222 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
223 databasenames. These are respectively expanded to the local system's temp directory
224 (including trailing delimiter) or to a prescribed data directory (including
225 trailing delimiter). Under Unix systems the data directory is a hidden directory
226 in the user's home directory. The hidden directory name is either the string returned
227 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
228 Under Windows, the directory is the same as the Data Directory as decribed
229 above but instead prefixed by the User's application data path. These may be
230 used to improve application portability for Personal Databases.
231
232 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
233 this has not worked for a long time and is not useful either. FieldDefs should be
234 managed using the Fields Editor as with any other dataset. To access the fields
235 editor for a TIBTable component, double click on the component. The fields editor
236 is then displayed.
237
238 28. TIBDatabaseInfo: new properties/function
239 * DateDBCreated (returns date/time database created)
240 * TransactionCount (returns no. of active transactions)
241 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
242 * PagesFree (Firebird 3 or later)
243 * PagesUsed (Firebird 3 or later)
244 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
245 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
246
247 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
248
249 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
250
251 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
252 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
253
254 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
255 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
256 firing during backup and restore.
257
258 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
259 for verbose output using the new property "StatisticsRequested".
260 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
261
262 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
263
264 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
265 palette. This uses the online validation feature added in Firebird 2.5. The
266 services's properties enable inclusion/exclusion of tables and indexes using
267 regular expressions. See.
268 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
269
270 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
271 option on a database.
272
273 37. TIBCustomService: Assign method implemented to allow copying of service login
274 context between service API components. "Detach" method now only detaches
275 service when last reference to the service interface detaches. Tidy up of
276 code for SetActive and Attach methods including password hiding.
277
278 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
279 and used to determine the auth method and protocol used for the connection.
280
281 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
282 a Create Database Statement generated by IBX.
283
284 40. All IBServices now have an additional published property "PortNo". This may
285 be set to a non-standard port number when necessary. If zero then the default
286 port number is used.
287
288 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
289 and not just the mouse.
290
291 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
292
293 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
294 image index and selected image index for each node to be set from a database field.
295
296 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
297 then database schema includes grants to all users. If not present then the
298 only user grants included are those to User PUBLIC.
299
300 45. TIBTreeView: performance improvement. When expanding include both expanded node
301 and child nodes in dataset.
302
303
304 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
305
306 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
307 changes.
308
309 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
310 Bug could result in truncated multi-byte character set values.
311
312 3. Changes consequential on moving fbintf character set utility functions from
313 IFirebirdAPI to IAttachment.
314
315 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
316
317 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
318 results in autocomplete ignoring prefix text.
319
320 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
321 entering a new name into the text box.
322
323 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
324 Firebird rather than recomputing it.
325
326 8. Property Editor positioning tidy up: All IBX Property editors should now be
327 screen centre. Previously some were "poDesigned" which may be inappropriate
328 for multi monitor desktops.
329
330 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
331
332 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
333 a transaction and always reset the object.
334
335 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
336
337 13. TIBXScript: Allow for override of database filename in Create Database statements.
338
339 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
340 to a gbak format archive.
341
342 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
343
344 16. IBLocaldb: Drop database if error creating an empty database.
345
346 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
347 unless selected node not in current dataset.
348
349 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
350 to TIBCustomService, and IBlocalDB code tidy up.
351
352 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
353 behaviour due to uninitialised variable.
354
355 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
356 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
357
358 21. IBSQL: When Database changed ensure that all resources are freed.
359
360 22. IBCustomDataset: When database changed ensure that queries an unprepared.
361
362 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
363 * Line Wrap on SQL Token boundaries (on user command)
364 * auto-complete table names in drop down list of table names
365 * Double click on tablename or field name adds to SQL text
366
367 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
368
369 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
370 TVariantArray. Seems to avoid memory corruption in Windows (probably a
371 workaround for a problem in fpc 3.0.4 win64).
372
373 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
374
375 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
376
377 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
378
379 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
380 include remote system name.
381
382 2. TIBExtract: No longer include comment header and COMMIT statement for empty
383 tables when data included in output.
384
385 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
386 and timing information to be written to stdout. This may be used to locate
387 performance bottlenecks.
388
389 4. SQLParser: only call "OnChanging" event handler when value is different.
390
391 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
392
393 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
394 that BindFields is called when the query is next activated. Avoids FieldName
395 not found error.
396
397 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
398 purpose and allows the programmer to define any action they want for Update, Insert
399 or Delete. This may be complex SQL (similar to a Trigger), application specific
400 filtering of updates, or use of statements such as Grant or Revoke instead of
401 normal DML. See User Manual for more information.
402
403 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
404
405 1. TIBEvents: Fix uninitialised variable that could result in lost events.
406
407 2. TIBExtract: Added support for FB3 "USAGE" privilege.
408
409 3. TIBExtract: data formatted as Charset set "octets" is now output using
410 hexadecimal notation.
411
412 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
413 using a simple XML format.
414
415 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
416 grants to these objects.
417
418 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
419 dependency problems restoring complex databases.
420
421 7. TIBXScript: This component has been restructured to allow for the processing of
422 embedded XML in INSERT statements and to support interactive sources in addition
423 to non-interactive data sources such as files.
424
425 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
426
427 9. TIBXScript: ISQL compatiable Set statements are now supported:
428 SET SQL DIALECT
429 SET TERM
430 SET AUTODDL
431 SET BAIL
432 SET ECHO
433 SET COUNT
434 SET STATS
435 SET NAMES <character set>
436
437 10. IBVersion unit added to hold current IBX Version Number information.
438
439 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
440 and domain definitions.
441
442 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
443 fully supported.
444
445 13. TIBExtract: when a database dump includes data, the generator values are now also set.
446
447 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
448
449 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
450
451 See also doc/IBX4LazarusGuide.pdf for important information on
452 upgrading to IBX2.
453
454 1. Size property of TIBStringField is now the width in characters of the field
455 and not the byte length. This applies only to multi-byte character sets such
456 as UTF8. The original approach aligned with TStringField. However, the TStringField
457 code is not recognised as a bug and hence this change to align the behaviour.
458 The TStringField change is expected in fpc 3.2.0.
459
460 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
461 true (default) then Size property value saved in the lfm is ignored. Size is
462 always set from the dynamic information read from the database. It is unclear
463 why anyone would want to override this and set Size to false.
464
465 3. ibxscript: should now handle correctly a Case..End statement within a procedure
466 block.
467
468 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
469 exist when an attempt is made to connect to it (run time only) then an attempt
470 is made to create the database.
471
472 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
473 has been successfully created as a result of a call to CreateDatabase or when
474 creating a database after it was found not to exist.
475
476 6. DBControlGrid: a race condition could result in the wrong row image being
477 written to the cache. This has been avoided by a trip round the message
478 loop before rendering the row image.
479
480 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
481 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
482 known to risk corrupt rendering of row images when the control is first
483 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
484 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
485
486 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
487 a TDateEdit control located on an editor panel.
488
489 9. TIBExtract: brought up-to-date plus many bug fixes.
490
491 10. DBControlGrid: Removed memory leak when updating rows.
492
493 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
494
495 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
496
497 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
498 when target codepage is CP_NONE. This is a workaround for
499 http://bugs.freepascal.org/view.php?id=30622.
500
501 2. DBLog option removed from TIBStatisticalService - not supported by server
502 since Firebird 1.5.
503
504 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
505 similar.
506
507 4. IBCodePage: updated mapping between codepages and character id.
508
509 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
510 Firebird. Character sets with a char width of two are not UTF16.
511
512 6. Strings received from the database are now always transliterated into UTF8
513 regardless of the database character set or connection character set. This
514 is for compatibility with the LCL.
515
516 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
517
518 1. IBBlob: Defer reading of blob until read method called. This avoids having to
519 read in an entire blob just to get the size of the blob. General performance
520 improvement when opening datasets containing blobs.
521
522 2. Clearing a Blob now sets the corresponding field's modified flag.
523
524 3. IBLookupCombo: When not performing auto-complete, original query sort order
525 is now used.
526
527 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
528 determined.
529
530 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
531
532 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
533 lazarus 1.6.0
534
535 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
536 compilation error.
537
538 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
539
540 1. No character set specified for connection: when a text blob is retrieved, the
541 character set is determined by looking up the native character set using then
542 Firebird API. Otherwise a text mode blob is assumed to have the same character
543 set as the connection.
544
545 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
546 for Login Dialog returing a change to the database path.
547
548 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
549 to be changed from that given in the TIBDatabase/TIBServer component and for the
550 entered value to be saved on a project specific basis (design time only).
551
552 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
553 column fieldname. If they are the same then it is acts as a look up for the KeyValue
554 Otherwise, it sets the column text to the selected ListField Value.
555
556 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
557 column width.
558
559 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
560 and a case insensitive search is requested.
561
562 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
563 or column ListSource.
564
565 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
566 unprepare) when closing and the text has not changed.
567
568 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
569 Less likely to cause a cursor re-use error on Windows.
570
571 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
572 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
573
574 11. TIBTreeView: Guard against nil destination on record changed
575
576 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
577 string type with the code page set to reflect the returned field encoding after
578 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
579 earlier versions.
580
581 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
582 will now result in transliteration to the code page specified for the Firebird driver
583 if the assigned string has a different code page. FPC 3.0.0 onwards only.
584
585 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
586 is ignored and the lc_ctype value, when the database is opened, is set to align with
587 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
588 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
589 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
590 the GETACP is used to determine the Windows code page.
591
592 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
593 name used as the lc_ctype when the database was opened. Only valid while the
594 Database is connected.
595
596 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
597 id that corresponds to the DefaultCharSetName.
598
599 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
600
601 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
602 path is given and database attach fails due to access permission issues on the
603 temp directory or security database, then the attach is retried with "localhost:"
604 prefixing the databasename. This should avoid problems when the database has to
605 be accessed by a local (e.g. classic) server and libfbembed is used.
606
607 2. Windows: revised search order for Firebird DLL:
608 i. The Firebird Embedded Server in the application Directory.
609 ii. If the FIREBIRD environment variable is set then the directory this
610 points to is searched for the FB Client DLL and then then underlying
611 "bin" directory.
612 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
613 is used to locate the Firebird installation directory and the underlying
614 "bin" directory is searched for the FB Client DLL.
615 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
616 are searched for the FB Client DLL.
617 v. The PATH Environment variable is used to search for the FB Client DLL.
618 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
619
620 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
621 See doc/readme.scriptengine and example applications.
622
623 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
624 simplify the use of the embedded firebird server on both Linux and Windows platforms.
625 See dpc/readme.localdatabase and example applications.
626
627 5. IBDynamicGrid: Reordering on column header click should now also work for
628 dynamic columns.
629
630 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
631 between incrementing/decrementing the lock count and signalling the event.
632
633 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
634
635 1.3.2 was never formally released and only made available as beta copies.
636
637 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
638
639 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
640
641 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
642
643 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
644 i.e. when it is a calculated field
645
646 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
647 This problem was due to a race condition between recalculating row heights and
648 determining which row was selected by the mouse click. The row height calculation
649 is now deferred by an extra trip round the message loop allowing the row to
650 be always calculated on the current grid layout rather than risking it being
651 calculated on the grid layout after the expanded row has been shrunk.
652
653 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
654 Windows.
655
656 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
657 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
658 to be determined at runtime. See doc/readme.charactersets.html.
659
660 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
661 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
662
663 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
664 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
665 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
666
667 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
668 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
669 implies no truncation.
670
671 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
672
673 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
674 (avoids "Not in Edit Mode" error).
675
676 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
677
678 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
679 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
680
681 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
682
683 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
684
685 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
686
687 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
688
689 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
690
691 1. OnCloseUp Event Handler added to TDBLookupProperties
692
693 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
694 problem with row size when exception is called.
695
696 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
697
698 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
699 in a TCustomComboBox and ignores return key if in a TCustomMemo
700
701 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
702 keyed in i.e. when autocomplete not performed
703
704 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
705 console mode applications with all LCL required functions (builtin dialogs and
706 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
707 not included in your project, IBX should compile and link with a console mode program.
708 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
709 console mode application or the IDE will automatically assume that your
710 application is GUI based. Instead, you should include the ibexpressconsolemode package.
711
712 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
713 to use the built in dialogs and cursor management. IBDialogs is
714 included by default if "ibexpress" is in your project source's "uses" clause.
715 This should be the case for all projects created through the IDE. This is why
716 you do not want to add the ibexpress package to console mode applications. The
717 ibexpressconsolemode package has been created to allow console mode programs
718 to avoid adding LCL dependencies when using IBX, while still having the
719 unit search paths set up correctly.
720
721 Existing users should check to ensure that the "ibexpress" unit is included in
722 each project's source file (*.lpr).
723
724 You may find that in order for the IDE to recognise that ibexpressconsolemode
725 exists, you have to first open the package in the IDE and then close it. This
726 adds it to the most recently accessed packages list. To make it permanently
727 available, add the package name to lazarus' staticpackages.inc file.
728
729 Thanks to Julio Jiménez for suggesting support of console mode.
730
731 7. SQL Parser can now accept quoted strings that include new lines
732
733 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
734 of text on start of edit. This is particularly useful when tabbing to a
735 column and then inserting text.
736
737 9. New Examples provided for IB Services and ISQLMonitor.
738
739 10. Fix error when writing to blob streams that recorded only the last buffer
740 write in the blob stream. In most cases, this did not cause a problem as the
741 IB Blob Stream is written in a single write. However, with the TDBImage, write
742 of a graphic type prefix was lost which caused a problem when the image could
743 not be automatically recognised.
744
745 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
746 already open" errors due to random numbers used for the cursor name being identical.
747
748 12. IBTable: corrected error that could result in an "Index out of bounds" error
749 when opening the table and the Primary Key is the last or only column in the
750 table. Thanks to Rick Hoover for the fix.
751
752 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
753 of "UTF-8", and update list of available database character sets. Existing
754 users should check the current lc_ctype setting in their applications.
755
756 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
757
758 1. Firebird Services: avoid List Index error when opening a service with an
759 empty Params property.
760
761 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
762 Link now set up in Loaded method - avoids occasional failure to apply
763 SQL markup on initial open.
764
765 3. "Employees" example performance improvements when scrolling.
766
767 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
768 TFrame. Force recaching of selected frame to avoid GTK race (results in a
769 random image cached).
770
771 5. DBControlGrid: Should now react to changes in panel height at run time.
772
773 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
774 even when further rows exist.
775
776 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
777 always be derived from panel height and setting this property can cause confusion.
778 Note for existing projects: to avoid a missing property error at run time,
779 each form using the DBControlGrid must be opened, updated and saved in the IDE
780 in order to remove the property value from the lfm.
781
782
783 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
784
785 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
786 call Prepare before setting parameter values.
787
788 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
789
790 3. Code tidyup and more robust handling of dsql information result vector.
791
792 4. Support for centralised handling of transaction status changes. TIBTransaction
793 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
794 and "AfterExecQuery". The first three are called after the same event is called
795 for an IBCustomDataSet descendent using the Transaction. The fourth is called
796 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
797 enable monitoring of transaction status changes for a given transaction to be
798 handled in a single place. For example, when a change to the dataset occurs
799 an indicator can be set that shows the user that in order to save changes,
800 the transaction should be committed. Rather than doing this per dataset, this
801 can now be done per transaction.
802
803 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
804 the dataset is scrolled. However, any changes to the current row are, by default,
805 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
806 have a new property "DataSetCloseAction" that adds automatic posting of changes
807 on dataset close. If this property is set to dcDiscardChanges (default) then the
808 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
809 then IBX will attempt to post any unsaved changes before the dataset is closed
810 (and after the BeforeClose event handler is called). The exception is when the
811 dataset is being closed as a result of a transaction rollback. In this case,
812 no action is taken and any unsaved changes are discarded. This avoids both
813 unnecessary overhead and the risk that a validation error may occur in the Post
814 raising an exception and thereby preventing a rollback.
815
816 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
817 In earlier versions, the Display Width was set to the maximum byte width rather than the character
818 width. Display Widths are now corrected by dividing by the max byte width per character.
819 For UTF8 character sets, the byte width is four and hence the Display Width will be
820 the byte width divided by 4. The byte width of each character set is determined
821 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
822 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
823
824 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
825
826 8. IBLookupComboEditBox: List should now always be restored to full list when the
827 control loses focus. Default Key press default interval reduced to 200ms.
828
829 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
830 when dataset rows are less than visible rows.
831
832 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
833 does not exist or DataSet is empty. More responsive on dataset open. New event
834 OnRestorePosition. Column sort disabled if no header row.
835
836 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
837 while dataset state is dsInsert. Avoids posting errors.
838
839 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
840 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
841
842 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
843
844 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
845 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
846 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
847 always "posts" the current record regardless or whether or not it may be more appropriate
848 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
849 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
850 as the first action of the "Post" method and allows the handler to convert the Post
851 into a Cancel if that is the appropriate action on moving to a different row. This is
852 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
853 raised here, but it may still be more appropriate to validate a post and signal
854 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
855
856 15. On Unix derived systems, the Firebird library name can now be given as a colon
857 separated list. Each library name on the list is tried in turn, in left to right
858 order with the first found being used as the firebird library. By default, on Linux,
859 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
860 overidden by the FBLIB environment variable or the OnGetLibraryName function.
861
862 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
863 then it will still attempt to access the database via the Firebird Server and will
864 require a username and password. If only the pathname is given, then the username
865 and password should be omitted and the unix file permissions are used to grant
866 access.
867
868 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
869
870 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
871 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
872 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
873 corresponds to a row of the linked DataSource. Any data aware control on the
874 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
875
876 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
877 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
878 takes place during database access. This may be useful when there are performance issues with
879 the change of cursor. Setting the property to false suppresses the change of cursor.
880
881 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
882 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
883 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
884 making all changes permanent immediately rather than when the transaction is explicitly
885 committed.
886
887 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
888 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
889
890 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
891
892 Development version only.
893
894 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
895
896 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
897 This is typically used during an "OnBeforeOpen" event handler to manipulate the
898 "Where" and "Having" clauses to implement user specified filters of arbitrary
899 complexity.
900
901 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
902 three new data aware controls dependent on IBX and which make use of the SQL Parser.
903 These are:
904
905 - TIBLookupComboEditBox
906 - TIBDynamicGrid
907 - TIBTreeview
908
909 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
910 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
911 to revise the available list and restrict it to items that are prefixed by the
912 typed text (either case sensitive or case insensitive). Autoinsert allows a
913 newly typed entry to be added to the list dataset and included in the available
914 list items.
915
916 TIBDynamicGrid is a TDBGrid descendent that provides for:
917 - automatic resizing of selected columns to fill the available row length
918 - automatic positioning and sizing of a "totals" control, typically at the
919 column footer, on a per column basis.
920 - DataSet resorting on header row click, sorting the dataset by the selected column.
921 A second click on the same header cell reversed the sort order.
922 - Support for a "Panel Editor". That is on clicking the indicator column, the row
923 is automatically expanded and a panel superimposed on it. The panel can have any
924 number of child controls, typically data aware controls with the same datasource
925 as the grid allowing for editing of additional fields and more complex editors.
926 - Reselection of the same row following resorting.
927 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
928 Its properties are specified on a per column basis and allows for one or more
929 columns to have their values selected from a list provided by a dataset.
930 Autocomplete and autoinsert are also available. The existing picklist editor
931 is unaffected by the extension.
932
933 TIBTreeView is a data aware TCustomTreeView.
934
935 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
936 zero scale will no longer return an error. An Int64 will be returned instead.
937
938 4. TIBTransaction now has events for Before and After Transaction End and a new function
939 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
940
941 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
942 repeated multiple times.
943
944 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
945 check used to get in the way of using Stored Procedures, and "Update or Insert"
946 statements.
947
948 7. Insert, Modify and Delete property Editors now support Query Generation from
949 Stored Procedures.
950
951 8. Three new examples illustrate the use of the new IB Controls

954 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
955
956 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
957 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
958 Gabor Boros for reporting this problem and for testing the improvements).
959
960 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
961 See readme.field+param.names in the doc folder.
962
963 3. IBX SQL Editors will now automatically add double quotes around column names when the database
964 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
965
966 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
967
968 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
969 actions.
970
971 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
972 thanks to Yuriy Kopnin for pointing this out).
973
974 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
975
976 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
977 for both fields and parameter setting.
978
979 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
980 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
981
982 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
983 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
984
985 11. TIBTable now has a property editor for "MasterFields"
986
987 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
988 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
989
990 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
991 of settings is unrecognised. Selecting this radio button has no effect on the settings.

996 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
997
998 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
999
1000 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1001 it is null. This allows for alternative user defined setting of the generator
1002
1003 Many thanks to Julio Jiménez for this fix
1004
1005 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1006 and suggests that the user may have forgotten to install it.
1007
1008 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1009
1010 1. Conditional compilation used to limit registration of TIntegerField to
1011 Lazarus versions less than 1.1
1012
1013 2. When a database connection is created, character set is now by default set
1014 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1015 1250 to 1254.
1016

1019
1020 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1021
1022
1023 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1024
1025 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1026 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1027
1028 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1029 package is changed to do this (which it should do).
1030
1031 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1032
1033 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1034
1035 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1036
1037 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1038
1039 4. Property editors should now correctly resize.
1040
1041 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1042 (restored original functionality)
1043
1044 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1045 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
