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

922
923 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
924 This is typically used during an "OnBeforeOpen" event handler to manipulate the
925 "Where" and "Having" clauses to implement user specified filters of arbitrary
926 complexity.
927
928 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
929 three new data aware controls dependent on IBX and which make use of the SQL Parser.
930 These are:
931
932 - TIBLookupComboEditBox
933 - TIBDynamicGrid
934 - TIBTreeview
935
936 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
937 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
938 to revise the available list and restrict it to items that are prefixed by the
939 typed text (either case sensitive or case insensitive). Autoinsert allows a
940 newly typed entry to be added to the list dataset and included in the available
941 list items.
942
943 TIBDynamicGrid is a TDBGrid descendent that provides for:
944 - automatic resizing of selected columns to fill the available row length
945 - automatic positioning and sizing of a "totals" control, typically at the
946 column footer, on a per column basis.
947 - DataSet resorting on header row click, sorting the dataset by the selected column.
948 A second click on the same header cell reversed the sort order.
949 - Support for a "Panel Editor". That is on clicking the indicator column, the row
950 is automatically expanded and a panel superimposed on it. The panel can have any
951 number of child controls, typically data aware controls with the same datasource
952 as the grid allowing for editing of additional fields and more complex editors.
953 - Reselection of the same row following resorting.
954 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
955 Its properties are specified on a per column basis and allows for one or more
956 columns to have their values selected from a list provided by a dataset.
957 Autocomplete and autoinsert are also available. The existing picklist editor
958 is unaffected by the extension.
959
960 TIBTreeView is a data aware TCustomTreeView.
961
962 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
963 zero scale will no longer return an error. An Int64 will be returned instead.
964
965 4. TIBTransaction now has events for Before and After Transaction End and a new function
966 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
967
968 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
969 repeated multiple times.
970
971 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
972 check used to get in the way of using Stored Procedures, and "Update or Insert"
973 statements.
974
975 7. Insert, Modify and Delete property Editors now support Query Generation from
976 Stored Procedures.
977
978 8. Three new examples illustrate the use of the new IB Controls
979

981 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
982
983 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
984 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
985 Gabor Boros for reporting this problem and for testing the improvements).
986
987 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
988 See readme.field+param.names in the doc folder.
989
990 3. IBX SQL Editors will now automatically add double quotes around column names when the database
991 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
992
993 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
994
995 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
996 actions.
997
998 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
999 thanks to Yuriy Kopnin for pointing this out).
1000
1001 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1002
1003 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1004 for both fields and parameter setting.
1005
1006 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1007 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1008
1009 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1010 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1011
1012 11. TIBTable now has a property editor for "MasterFields"
1013
1014 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1015 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1016
1017 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1018 of settings is unrecognised. Selecting this radio button has no effect on the settings.

1022
1023 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1024
1025 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1026
1027 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1028 it is null. This allows for alternative user defined setting of the generator
1029
1030 Many thanks to Julio Jiménez for this fix
1031
1032 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1033 and suggests that the user may have forgotten to install it.
1034
1035 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1036
1037 1. Conditional compilation used to limit registration of TIntegerField to
1038 Lazarus versions less than 1.1
1039
1040 2. When a database connection is created, character set is now by default set
1041 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1042 1250 to 1254.
1043

1050 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1051
1052 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1053 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1054
1055 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1056 package is changed to do this (which it should do).
1057
1058 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1059
1060 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1061
1062 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1063
1064 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1065
1066 4. Property editors should now correctly resize.
1067
1068 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1069 (restored original functionality)
1070
1071 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1072 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
