1 IBX Change Log version (2.0-3) Fri, 13 Oct 2017 12:19:52 +0100
2
3 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 changes.
5
6 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 Bug could result in truncated multi-byte character set values.
8
9 3. Changes consequential on moving fbintf character set utility functions from
10 IFirebirdAPI to IAttachment.
11
12 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
13
14 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 results in autocomplete ignoring prefix text.
16
17 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 entering a new name into the text box.
19
20 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21 Firebird rather than recomputing it.
22
23 8. Property Editor positioning tidy up: All IBX Property editors should now be
24 screen centre. Previously some were "poDesigned" which may be inappropriate
25 for multi monitor desktops.
26
27 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
28
29 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
30 include remote system name.
31
32 2. TIBExtract: No longer include comment header and COMMIT statement for empty
33 tables when data included in output.
34
35 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
36 and timing information to be written to stdout. This may be used to locate
37 performance bottlenecks.
38
39 4. SQLParser: only call "OnChanging" event handler when value is different.
40
41 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
42
43 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
44 that BindFields is called when the query is next activated. Avoids FieldName
45 not found error.
46
47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
48
49 1. TIBEvents: Fix uninitialised variable that could result in lost events.
50
51 2. TIBExtract: Added support for FB3 "USAGE" privilege.
52
53 3. TIBExtract: data formatted as Charset set "octets" is now output using
54 hexadecimal notation.
55
56 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
57 using a simple XML format.
58
59 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
60 grants to these objects.
61
62 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
63 dependency problems restoring complex databases.
64
65 7. TIBXScript: This component has been restructured to allow for the processing of
66 embedded XML in INSERT statements and to support interactive sources in addition
67 to non-interactive data sources such as files.
68
69 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
70
71 9. TIBXScript: ISQL compatiable Set statements are now supported:
72 SET SQL DIALECT
73 SET TERM
74 SET AUTODDL
75 SET BAIL
76 SET ECHO
77 SET COUNT
78 SET STATS
79 SET NAMES <character set>
80
81 10. IBVersion unit added to hold current IBX Version Number information.
82
83 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
84 and domain definitions.
85
86 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
87 fully supported.
88
89 13. TIBExtract: when a database dump includes data, the generator values are now also set.
90
91 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
92
93 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
94
95 See also doc/IBX4LazarusGuide.pdf for important information on
96 upgrading to IBX2.
97
98 1. Size property of TIBStringField is now the width in characters of the field
99 and not the byte length. This applies only to multi-byte character sets such
100 as UTF8. The original approach aligned with TStringField. However, the TStringField
101 code is not recognised as a bug and hence this change to align the behaviour.
102 The TStringField change is expected in fpc 3.2.0.
103
104 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
105 true (default) then Size property value saved in the lfm is ignored. Size is
106 always set from the dynamic information read from the database. It is unclear
107 why anyone would want to override this and set Size to false.
108
109 3. ibxscript: should now handle correctly a Case..End statement within a procedure
110 block.
111
112 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
113 exist when an attempt is made to connect to it (run time only) then an attempt
114 is made to create the database.
115
116 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
117 has been successfully created as a result of a call to CreateDatabase or when
118 creating a database after it was found not to exist.
119
120 6. DBControlGrid: a race condition could result in the wrong row image being
121 written to the cache. This has been avoided by a trip round the message
122 loop before rendering the row image.
123
124 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
125 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
126 known to risk corrupt rendering of row images when the control is first
127 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
128 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
129
130 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
131 a TDateEdit control located on an editor panel.
132
133 9. TIBExtract: brought up-to-date plus many bug fixes.
134
135 10. DBControlGrid: Removed memory leak when updating rows.
136
137 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
138
139 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
140
141 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
142 when target codepage is CP_NONE. This is a workaround for
143 http://bugs.freepascal.org/view.php?id=30622.
144
145 2. DBLog option removed from TIBStatisticalService - not supported by server
146 since Firebird 1.5.
147
148 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
149 similar.
150
151 4. IBCodePage: updated mapping between codepages and character id.
152
153 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
154 Firebird. Character sets with a char width of two are not UTF16.
155
156 6. Strings received from the database are now always transliterated into UTF8
157 regardless of the database character set or connection character set. This
158 is for compatibility with the LCL.
159
160 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
161
162 1. IBBlob: Defer reading of blob until read method called. This avoids having to
163 read in an entire blob just to get the size of the blob. General performance
164 improvement when opening datasets containing blobs.
165
166 2. Clearing a Blob now sets the corresponding field's modified flag.
167
168 3. IBLookupCombo: When not performing auto-complete, original query sort order
169 is now used.
170
171 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
172 determined.
173
174 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
175
176 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
177 lazarus 1.6.0
178
179 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
180 compilation error.
181
182 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
183
184 1. No character set specified for connection: when a text blob is retrieved, the
185 character set is determined by looking up the native character set using then
186 Firebird API. Otherwise a text mode blob is assumed to have the same character
187 set as the connection.
188
189 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
190 for Login Dialog returing a change to the database path.
191
192 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
193 to be changed from that given in the TIBDatabase/TIBServer component and for the
194 entered value to be saved on a project specific basis (design time only).
195
196 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
197 column fieldname. If they are the same then it is acts as a look up for the KeyValue
198 Otherwise, it sets the column text to the selected ListField Value.
199
200 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
201 column width.
202
203 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
204 and a case insensitive search is requested.
205
206 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
207 or column ListSource.
208
209 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
210 unprepare) when closing and the text has not changed.
211
212 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
213 Less likely to cause a cursor re-use error on Windows.
214
215 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
216 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
217
218 11. TIBTreeView: Guard against nil destination on record changed
219
220 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
221 string type with the code page set to reflect the returned field encoding after
222 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
223 earlier versions.
224
225 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
226 will now result in transliteration to the code page specified for the Firebird driver
227 if the assigned string has a different code page. FPC 3.0.0 onwards only.
228
229 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
230 is ignored and the lc_ctype value, when the database is opened, is set to align with
231 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
232 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
233 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
234 the GETACP is used to determine the Windows code page.
235
236 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
237 name used as the lc_ctype when the database was opened. Only valid while the
238 Database is connected.
239
240 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
241 id that corresponds to the DefaultCharSetName.
242
243 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
244
245 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
246 path is given and database attach fails due to access permission issues on the
247 temp directory or security database, then the attach is retried with "localhost:"
248 prefixing the databasename. This should avoid problems when the database has to
249 be accessed by a local (e.g. classic) server and libfbembed is used.
250
251 2. Windows: revised search order for Firebird DLL:
252 i. The Firebird Embedded Server in the application Directory.
253 ii. If the FIREBIRD environment variable is set then the directory this
254 points to is searched for the FB Client DLL and then then underlying
255 "bin" directory.
256 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
257 is used to locate the Firebird installation directory and the underlying
258 "bin" directory is searched for the FB Client DLL.
259 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
260 are searched for the FB Client DLL.
261 v. The PATH Environment variable is used to search for the FB Client DLL.
262 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
263
264 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
265 See doc/readme.scriptengine and example applications.
266
267 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
268 simplify the use of the embedded firebird server on both Linux and Windows platforms.
269 See dpc/readme.localdatabase and example applications.
270
271 5. IBDynamicGrid: Reordering on column header click should now also work for
272 dynamic columns.
273
274 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
275 between incrementing/decrementing the lock count and signalling the event.
276
277 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
278
279 1.3.2 was never formally released and only made available as beta copies.
280
281 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
282
283 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
284
285 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
286
287 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
288 i.e. when it is a calculated field
289
290 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
291 This problem was due to a race condition between recalculating row heights and
292 determining which row was selected by the mouse click. The row height calculation
293 is now deferred by an extra trip round the message loop allowing the row to
294 be always calculated on the current grid layout rather than risking it being
295 calculated on the grid layout after the expanded row has been shrunk.
296
297 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
298 Windows.
299
300 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
301 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
302 to be determined at runtime. See doc/readme.charactersets.html.
303
304 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
305 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
306
307 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
308 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
309 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
310
311 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
312 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
313 implies no truncation.
314
315 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
316
317 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
318 (avoids "Not in Edit Mode" error).
319
320 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
321
322 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
323 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
324
325 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
326
327 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
328
329 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
330
331 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
332
333 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
334
335 1. OnCloseUp Event Handler added to TDBLookupProperties
336
337 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
338 problem with row size when exception is called.
339
340 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
341
342 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
343 in a TCustomComboBox and ignores return key if in a TCustomMemo
344
345 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
346 keyed in i.e. when autocomplete not performed
347
348 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
349 console mode applications with all LCL required functions (builtin dialogs and
350 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
351 not included in your project, IBX should compile and link with a console mode program.
352 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
353 console mode application or the IDE will automatically assume that your
354 application is GUI based. Instead, you should include the ibexpressconsolemode package.
355
356 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
357 to use the built in dialogs and cursor management. IBDialogs is
358 included by default if "ibexpress" is in your project source's "uses" clause.
359 This should be the case for all projects created through the IDE. This is why
360 you do not want to add the ibexpress package to console mode applications. The
361 ibexpressconsolemode package has been created to allow console mode programs
362 to avoid adding LCL dependencies when using IBX, while still having the
363 unit search paths set up correctly.
364
365 Existing users should check to ensure that the "ibexpress" unit is included in
366 each project's source file (*.lpr).
367
368 You may find that in order for the IDE to recognise that ibexpressconsolemode
369 exists, you have to first open the package in the IDE and then close it. This
370 adds it to the most recently accessed packages list. To make it permanently
371 available, add the package name to lazarus' staticpackages.inc file.
372
373 Thanks to Julio Jiménez for suggesting support of console mode.
374
375 7. SQL Parser can now accept quoted strings that include new lines
376
377 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
378 of text on start of edit. This is particularly useful when tabbing to a
379 column and then inserting text.
380
381 9. New Examples provided for IB Services and ISQLMonitor.
382
383 10. Fix error when writing to blob streams that recorded only the last buffer
384 write in the blob stream. In most cases, this did not cause a problem as the
385 IB Blob Stream is written in a single write. However, with the TDBImage, write
386 of a graphic type prefix was lost which caused a problem when the image could
387 not be automatically recognised.
388
389 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
390 already open" errors due to random numbers used for the cursor name being identical.
391
392 12. IBTable: corrected error that could result in an "Index out of bounds" error
393 when opening the table and the Primary Key is the last or only column in the
394 table. Thanks to Rick Hoover for the fix.
395
396 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
397 of "UTF-8", and update list of available database character sets. Existing
398 users should check the current lc_ctype setting in their applications.
399
400 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
401
402 1. Firebird Services: avoid List Index error when opening a service with an
403 empty Params property.
404
405 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
406 Link now set up in Loaded method - avoids occasional failure to apply
407 SQL markup on initial open.
408
409 3. "Employees" example performance improvements when scrolling.
410
411 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
412 TFrame. Force recaching of selected frame to avoid GTK race (results in a
413 random image cached).
414
415 5. DBControlGrid: Should now react to changes in panel height at run time.
416
417 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
418 even when further rows exist.
419
420 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
421 always be derived from panel height and setting this property can cause confusion.
422 Note for existing projects: to avoid a missing property error at run time,
423 each form using the DBControlGrid must be opened, updated and saved in the IDE
424 in order to remove the property value from the lfm.
425
426
427 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
428
429 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
430 call Prepare before setting parameter values.
431
432 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
433
434 3. Code tidyup and more robust handling of dsql information result vector.
435
436 4. Support for centralised handling of transaction status changes. TIBTransaction
437 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
438 and "AfterExecQuery". The first three are called after the same event is called
439 for an IBCustomDataSet descendent using the Transaction. The fourth is called
440 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
441 enable monitoring of transaction status changes for a given transaction to be
442 handled in a single place. For example, when a change to the dataset occurs
443 an indicator can be set that shows the user that in order to save changes,
444 the transaction should be committed. Rather than doing this per dataset, this
445 can now be done per transaction.
446
447 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
448 the dataset is scrolled. However, any changes to the current row are, by default,
449 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
450 have a new property "DataSetCloseAction" that adds automatic posting of changes
451 on dataset close. If this property is set to dcDiscardChanges (default) then the
452 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
453 then IBX will attempt to post any unsaved changes before the dataset is closed
454 (and after the BeforeClose event handler is called). The exception is when the
455 dataset is being closed as a result of a transaction rollback. In this case,
456 no action is taken and any unsaved changes are discarded. This avoids both
457 unnecessary overhead and the risk that a validation error may occur in the Post
458 raising an exception and thereby preventing a rollback.
459
460 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
461 In earlier versions, the Display Width was set to the maximum byte width rather than the character
462 width. Display Widths are now corrected by dividing by the max byte width per character.
463 For UTF8 character sets, the byte width is four and hence the Display Width will be
464 the byte width divided by 4. The byte width of each character set is determined
465 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
466 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
467
468 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
469
470 8. IBLookupComboEditBox: List should now always be restored to full list when the
471 control loses focus. Default Key press default interval reduced to 200ms.
472
473 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
474 when dataset rows are less than visible rows.
475
476 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
477 does not exist or DataSet is empty. More responsive on dataset open. New event
478 OnRestorePosition. Column sort disabled if no header row.
479
480 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
481 while dataset state is dsInsert. Avoids posting errors.
482
483 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
484 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
485
486 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
487
488 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
489 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
490 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
491 always "posts" the current record regardless or whether or not it may be more appropriate
492 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
493 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
494 as the first action of the "Post" method and allows the handler to convert the Post
495 into a Cancel if that is the appropriate action on moving to a different row. This is
496 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
497 raised here, but it may still be more appropriate to validate a post and signal
498 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
499
500 15. On Unix derived systems, the Firebird library name can now be given as a colon
501 separated list. Each library name on the list is tried in turn, in left to right
502 order with the first found being used as the firebird library. By default, on Linux,
503 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
504 overidden by the FBLIB environment variable or the OnGetLibraryName function.
505
506 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
507 then it will still attempt to access the database via the Firebird Server and will
508 require a username and password. If only the pathname is given, then the username
509 and password should be omitted and the unix file permissions are used to grant
510 access.

512 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
513
514 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
515 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
516 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
517 corresponds to a row of the linked DataSource. Any data aware control on the
518 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
519
520 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
521 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
522 takes place during database access. This may be useful when there are performance issues with
523 the change of cursor. Setting the property to false suppresses the change of cursor.
524
525 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
526 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
527 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
528 making all changes permanent immediately rather than when the transaction is explicitly
529 committed.
530
531 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
532 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
533
534 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
535
536 Development version only.
537
538 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
539
540 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
541 This is typically used during an "OnBeforeOpen" event handler to manipulate the
542 "Where" and "Having" clauses to implement user specified filters of arbitrary
543 complexity.
544
545 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
546 three new data aware controls dependent on IBX and which make use of the SQL Parser.
547 These are:
548
549 - TIBLookupComboEditBox
550 - TIBDynamicGrid
551 - TIBTreeview
552
553 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
554 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
555 to revise the available list and restrict it to items that are prefixed by the
556 typed text (either case sensitive or case insensitive). Autoinsert allows a
557 newly typed entry to be added to the list dataset and included in the available
558 list items.
559
560 TIBDynamicGrid is a TDBGrid descendent that provides for:
561 - automatic resizing of selected columns to fill the available row length
562 - automatic positioning and sizing of a "totals" control, typically at the
563 column footer, on a per column basis.
564 - DataSet resorting on header row click, sorting the dataset by the selected column.
565 A second click on the same header cell reversed the sort order.
566 - Support for a "Panel Editor". That is on clicking the indicator column, the row
567 is automatically expanded and a panel superimposed on it. The panel can have any
568 number of child controls, typically data aware controls with the same datasource
569 as the grid allowing for editing of additional fields and more complex editors.
570 - Reselection of the same row following resorting.
571 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
572 Its properties are specified on a per column basis and allows for one or more
573 columns to have their values selected from a list provided by a dataset.
574 Autocomplete and autoinsert are also available. The existing picklist editor
575 is unaffected by the extension.
576
577 TIBTreeView is a data aware TCustomTreeView.
578
579 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
580 zero scale will no longer return an error. An Int64 will be returned instead.
581
582 4. TIBTransaction now has events for Before and After Transaction End and a new function
583 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
584
585 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
586 repeated multiple times.
587
588 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
589 check used to get in the way of using Stored Procedures, and "Update or Insert"
590 statements.
591
592 7. Insert, Modify and Delete property Editors now support Query Generation from
593 Stored Procedures.
594
595 8. Three new examples illustrate the use of the new IB Controls
596

598 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
599
600 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
601 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
602 Gabor Boros for reporting this problem and for testing the improvements).
603
604 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
605 See readme.field+param.names in the doc folder.
606
607 3. IBX SQL Editors will now automatically add double quotes around column names when the database
608 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
609
610 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
611
612 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
613 actions.
614
615 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
616 thanks to Yuriy Kopnin for pointing this out).
617
618 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
619
620 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
621 for both fields and parameter setting.
622
623 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
624 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
625
626 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
627 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
628
629 11. TIBTable now has a property editor for "MasterFields"
630
631 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
632 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
633
634 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
635 of settings is unrecognised. Selecting this radio button has no effect on the settings.
636

638 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
639
640 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
641
642 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
643
644 1. In a TIBCustomDataset descendent, a generator now only sets the value when
645 it is null. This allows for alternative user defined setting of the generator
646
647 Many thanks to Julio Jiménez for this fix
648
649 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
650 and suggests that the user may have forgotten to install it.
651
652 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
653
654 1. Conditional compilation used to limit registration of TIntegerField to
655 Lazarus versions less than 1.1
656
657 2. When a database connection is created, character set is now by default set
658 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
659 1250 to 1254.
660
661
662 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
663
664 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
665
666
667 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
668
669 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
670 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
671
672 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
673 package is changed to do this (which it should do).
674
675 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
676
677 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
678
679 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
680
681 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
682
683 4. Property editors should now correctly resize.
684
685 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
686 (restored original functionality)
687
688 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
689 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
