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

939 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
940
941 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
942 This is typically used during an "OnBeforeOpen" event handler to manipulate the
943 "Where" and "Having" clauses to implement user specified filters of arbitrary
944 complexity.
945
946 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
947 three new data aware controls dependent on IBX and which make use of the SQL Parser.
948 These are:
949
950 - TIBLookupComboEditBox
951 - TIBDynamicGrid
952 - TIBTreeview
953
954 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
955 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
956 to revise the available list and restrict it to items that are prefixed by the
957 typed text (either case sensitive or case insensitive). Autoinsert allows a
958 newly typed entry to be added to the list dataset and included in the available
959 list items.
960
961 TIBDynamicGrid is a TDBGrid descendent that provides for:
962 - automatic resizing of selected columns to fill the available row length
963 - automatic positioning and sizing of a "totals" control, typically at the
964 column footer, on a per column basis.
965 - DataSet resorting on header row click, sorting the dataset by the selected column.
966 A second click on the same header cell reversed the sort order.
967 - Support for a "Panel Editor". That is on clicking the indicator column, the row
968 is automatically expanded and a panel superimposed on it. The panel can have any
969 number of child controls, typically data aware controls with the same datasource
970 as the grid allowing for editing of additional fields and more complex editors.
971 - Reselection of the same row following resorting.
972 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
973 Its properties are specified on a per column basis and allows for one or more
974 columns to have their values selected from a list provided by a dataset.
975 Autocomplete and autoinsert are also available. The existing picklist editor
976 is unaffected by the extension.
977
978 TIBTreeView is a data aware TCustomTreeView.
979
980 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
981 zero scale will no longer return an error. An Int64 will be returned instead.
982
983 4. TIBTransaction now has events for Before and After Transaction End and a new function
984 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
985
986 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
987 repeated multiple times.
988
989 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
990 check used to get in the way of using Stored Procedures, and "Update or Insert"
991 statements.
992
993 7. Insert, Modify and Delete property Editors now support Query Generation from
994 Stored Procedures.
995
996 8. Three new examples illustrate the use of the new IB Controls
997

999 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1000
1001 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1002 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1003 Gabor Boros for reporting this problem and for testing the improvements).
1004
1005 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1006 See readme.field+param.names in the doc folder.
1007
1008 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1009 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1010
1011 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1012
1013 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1014 actions.
1015
1016 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1017 thanks to Yuriy Kopnin for pointing this out).
1018
1019 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1020
1021 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1022 for both fields and parameter setting.
1023
1024 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1025 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1026
1027 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1028 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1029
1030 11. TIBTable now has a property editor for "MasterFields"
1031
1032 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1033 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1034
1035 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1036 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1037

1039 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1040
1041 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1042
1043 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1044
1045 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1046 it is null. This allows for alternative user defined setting of the generator
1047
1048 Many thanks to Julio Jiménez for this fix
1049
1050 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1051 and suggests that the user may have forgotten to install it.
1052
1053 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1054
1055 1. Conditional compilation used to limit registration of TIntegerField to
1056 Lazarus versions less than 1.1
1057
1058 2. When a database connection is created, character set is now by default set
1059 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1060 1250 to 1254.
1061
1062
1063 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1064
1065 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1066
1067
1068 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1069
1070 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1071 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1072
1073 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1074 package is changed to do this (which it should do).
1075
1076 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1077
1078 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1079
1080 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1081
1082 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1083
1084 4. Property editors should now correctly resize.
1085
1086 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1087 (restored original functionality)
1088
1089 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1090 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
