1 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
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 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
28
29 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
30 a transaction and always reset the object.
31
32 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
33
34 13. TIBXScript: Allow for override of database filename in Create Database statements.
35
36 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
37 to a gbak format archive.
38
39 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
40
41 16. IBLocaldb: Drop database if error creating an empty database.
42
43 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
44 unless selected node not in current dataset.
45
46 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
47 to TIBCustomService, and IBlocalDB code tidy up.
48
49 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
50 behaviour due to uninitialised variable.
51
52 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
53 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
54
55 21. IBSQL: When Database changed ensure that all resources are freed.
56
57 22. IBCustomDataset: When database changed ensure that queries an unprepared.
58
59 23. SQL Property Editors now use SynEdit with SQL Highlighter.
60
61 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
62
63 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
64 TVariantArray. Seems to avoid memory corruption in Windows (probably a
65 workaround for a problem in fpc 3.0.4 win64).
66
67 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
68
69 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
70
71 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
72 include remote system name.
73
74 2. TIBExtract: No longer include comment header and COMMIT statement for empty
75 tables when data included in output.
76
77 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
78 and timing information to be written to stdout. This may be used to locate
79 performance bottlenecks.
80
81 4. SQLParser: only call "OnChanging" event handler when value is different.
82
83 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
84
85 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
86 that BindFields is called when the query is next activated. Avoids FieldName
87 not found error.
88
89 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
90 purpose and allows the programmer to define any action they want for Update, Insert
91 or Delete. This may be complex SQL (similar to a Trigger), application specific
92 filtering of updates, or use of statements such as Grant or Revoke instead of
93 normal DML. See User Manual for more information.
94
95 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
96
97 1. TIBEvents: Fix uninitialised variable that could result in lost events.
98
99 2. TIBExtract: Added support for FB3 "USAGE" privilege.
100
101 3. TIBExtract: data formatted as Charset set "octets" is now output using
102 hexadecimal notation.
103
104 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
105 using a simple XML format.
106
107 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
108 grants to these objects.
109
110 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
111 dependency problems restoring complex databases.
112
113 7. TIBXScript: This component has been restructured to allow for the processing of
114 embedded XML in INSERT statements and to support interactive sources in addition
115 to non-interactive data sources such as files.
116
117 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
118
119 9. TIBXScript: ISQL compatiable Set statements are now supported:
120 SET SQL DIALECT
121 SET TERM
122 SET AUTODDL
123 SET BAIL
124 SET ECHO
125 SET COUNT
126 SET STATS
127 SET NAMES <character set>
128
129 10. IBVersion unit added to hold current IBX Version Number information.
130
131 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
132 and domain definitions.
133
134 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
135 fully supported.
136
137 13. TIBExtract: when a database dump includes data, the generator values are now also set.
138
139 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
140
141 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
142
143 See also doc/IBX4LazarusGuide.pdf for important information on
144 upgrading to IBX2.
145
146 1. Size property of TIBStringField is now the width in characters of the field
147 and not the byte length. This applies only to multi-byte character sets such
148 as UTF8. The original approach aligned with TStringField. However, the TStringField
149 code is not recognised as a bug and hence this change to align the behaviour.
150 The TStringField change is expected in fpc 3.2.0.
151
152 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
153 true (default) then Size property value saved in the lfm is ignored. Size is
154 always set from the dynamic information read from the database. It is unclear
155 why anyone would want to override this and set Size to false.
156
157 3. ibxscript: should now handle correctly a Case..End statement within a procedure
158 block.
159
160 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
161 exist when an attempt is made to connect to it (run time only) then an attempt
162 is made to create the database.
163
164 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
165 has been successfully created as a result of a call to CreateDatabase or when
166 creating a database after it was found not to exist.
167
168 6. DBControlGrid: a race condition could result in the wrong row image being
169 written to the cache. This has been avoided by a trip round the message
170 loop before rendering the row image.
171
172 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
173 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
174 known to risk corrupt rendering of row images when the control is first
175 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
176 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
177
178 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
179 a TDateEdit control located on an editor panel.
180
181 9. TIBExtract: brought up-to-date plus many bug fixes.
182
183 10. DBControlGrid: Removed memory leak when updating rows.
184
185 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
186
187 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
188
189 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
190 when target codepage is CP_NONE. This is a workaround for
191 http://bugs.freepascal.org/view.php?id=30622.
192
193 2. DBLog option removed from TIBStatisticalService - not supported by server
194 since Firebird 1.5.
195
196 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
197 similar.
198
199 4. IBCodePage: updated mapping between codepages and character id.
200
201 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
202 Firebird. Character sets with a char width of two are not UTF16.
203
204 6. Strings received from the database are now always transliterated into UTF8
205 regardless of the database character set or connection character set. This
206 is for compatibility with the LCL.
207
208 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
209
210 1. IBBlob: Defer reading of blob until read method called. This avoids having to
211 read in an entire blob just to get the size of the blob. General performance
212 improvement when opening datasets containing blobs.
213
214 2. Clearing a Blob now sets the corresponding field's modified flag.
215
216 3. IBLookupCombo: When not performing auto-complete, original query sort order
217 is now used.
218
219 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
220 determined.
221
222 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
223
224 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
225 lazarus 1.6.0
226
227 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
228 compilation error.
229
230 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
231
232 1. No character set specified for connection: when a text blob is retrieved, the
233 character set is determined by looking up the native character set using then
234 Firebird API. Otherwise a text mode blob is assumed to have the same character
235 set as the connection.
236
237 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
238 for Login Dialog returing a change to the database path.
239
240 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
241 to be changed from that given in the TIBDatabase/TIBServer component and for the
242 entered value to be saved on a project specific basis (design time only).
243
244 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
245 column fieldname. If they are the same then it is acts as a look up for the KeyValue
246 Otherwise, it sets the column text to the selected ListField Value.
247
248 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
249 column width.
250
251 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
252 and a case insensitive search is requested.
253
254 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
255 or column ListSource.
256
257 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
258 unprepare) when closing and the text has not changed.
259
260 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
261 Less likely to cause a cursor re-use error on Windows.
262
263 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
264 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
265
266 11. TIBTreeView: Guard against nil destination on record changed
267
268 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
269 string type with the code page set to reflect the returned field encoding after
270 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
271 earlier versions.
272
273 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
274 will now result in transliteration to the code page specified for the Firebird driver
275 if the assigned string has a different code page. FPC 3.0.0 onwards only.
276
277 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
278 is ignored and the lc_ctype value, when the database is opened, is set to align with
279 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
280 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
281 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
282 the GETACP is used to determine the Windows code page.
283
284 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
285 name used as the lc_ctype when the database was opened. Only valid while the
286 Database is connected.
287
288 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
289 id that corresponds to the DefaultCharSetName.
290
291 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
292
293 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
294 path is given and database attach fails due to access permission issues on the
295 temp directory or security database, then the attach is retried with "localhost:"
296 prefixing the databasename. This should avoid problems when the database has to
297 be accessed by a local (e.g. classic) server and libfbembed is used.
298
299 2. Windows: revised search order for Firebird DLL:
300 i. The Firebird Embedded Server in the application Directory.
301 ii. If the FIREBIRD environment variable is set then the directory this
302 points to is searched for the FB Client DLL and then then underlying
303 "bin" directory.
304 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
305 is used to locate the Firebird installation directory and the underlying
306 "bin" directory is searched for the FB Client DLL.
307 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
308 are searched for the FB Client DLL.
309 v. The PATH Environment variable is used to search for the FB Client DLL.
310 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
311
312 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
313 See doc/readme.scriptengine and example applications.
314
315 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
316 simplify the use of the embedded firebird server on both Linux and Windows platforms.
317 See dpc/readme.localdatabase and example applications.
318
319 5. IBDynamicGrid: Reordering on column header click should now also work for
320 dynamic columns.
321
322 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
323 between incrementing/decrementing the lock count and signalling the event.
324
325 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
326
327 1.3.2 was never formally released and only made available as beta copies.
328
329 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
330
331 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
332
333 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
334
335 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
336 i.e. when it is a calculated field
337
338 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
339 This problem was due to a race condition between recalculating row heights and
340 determining which row was selected by the mouse click. The row height calculation
341 is now deferred by an extra trip round the message loop allowing the row to
342 be always calculated on the current grid layout rather than risking it being
343 calculated on the grid layout after the expanded row has been shrunk.
344
345 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
346 Windows.
347
348 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
349 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
350 to be determined at runtime. See doc/readme.charactersets.html.
351
352 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
353 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
354
355 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
356 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
357 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
358
359 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
360 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
361 implies no truncation.
362
363 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
364
365 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
366 (avoids "Not in Edit Mode" error).
367
368 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
369
370 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
371 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
372
373 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
374
375 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
376
377 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
378
379 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
380
381 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
382
383 1. OnCloseUp Event Handler added to TDBLookupProperties
384
385 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
386 problem with row size when exception is called.
387
388 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
389
390 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
391 in a TCustomComboBox and ignores return key if in a TCustomMemo
392
393 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
394 keyed in i.e. when autocomplete not performed
395
396 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
397 console mode applications with all LCL required functions (builtin dialogs and
398 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
399 not included in your project, IBX should compile and link with a console mode program.
400 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
401 console mode application or the IDE will automatically assume that your
402 application is GUI based. Instead, you should include the ibexpressconsolemode package.
403
404 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
405 to use the built in dialogs and cursor management. IBDialogs is
406 included by default if "ibexpress" is in your project source's "uses" clause.
407 This should be the case for all projects created through the IDE. This is why
408 you do not want to add the ibexpress package to console mode applications. The
409 ibexpressconsolemode package has been created to allow console mode programs
410 to avoid adding LCL dependencies when using IBX, while still having the
411 unit search paths set up correctly.
412
413 Existing users should check to ensure that the "ibexpress" unit is included in
414 each project's source file (*.lpr).
415
416 You may find that in order for the IDE to recognise that ibexpressconsolemode
417 exists, you have to first open the package in the IDE and then close it. This
418 adds it to the most recently accessed packages list. To make it permanently
419 available, add the package name to lazarus' staticpackages.inc file.
420
421 Thanks to Julio Jiménez for suggesting support of console mode.
422
423 7. SQL Parser can now accept quoted strings that include new lines
424
425 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
426 of text on start of edit. This is particularly useful when tabbing to a
427 column and then inserting text.
428
429 9. New Examples provided for IB Services and ISQLMonitor.
430
431 10. Fix error when writing to blob streams that recorded only the last buffer
432 write in the blob stream. In most cases, this did not cause a problem as the
433 IB Blob Stream is written in a single write. However, with the TDBImage, write
434 of a graphic type prefix was lost which caused a problem when the image could
435 not be automatically recognised.
436
437 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
438 already open" errors due to random numbers used for the cursor name being identical.
439
440 12. IBTable: corrected error that could result in an "Index out of bounds" error
441 when opening the table and the Primary Key is the last or only column in the
442 table. Thanks to Rick Hoover for the fix.
443
444 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
445 of "UTF-8", and update list of available database character sets. Existing
446 users should check the current lc_ctype setting in their applications.
447
448 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
449
450 1. Firebird Services: avoid List Index error when opening a service with an
451 empty Params property.
452
453 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
454 Link now set up in Loaded method - avoids occasional failure to apply
455 SQL markup on initial open.
456
457 3. "Employees" example performance improvements when scrolling.
458
459 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
460 TFrame. Force recaching of selected frame to avoid GTK race (results in a
461 random image cached).
462
463 5. DBControlGrid: Should now react to changes in panel height at run time.
464
465 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
466 even when further rows exist.
467
468 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
469 always be derived from panel height and setting this property can cause confusion.
470 Note for existing projects: to avoid a missing property error at run time,
471 each form using the DBControlGrid must be opened, updated and saved in the IDE
472 in order to remove the property value from the lfm.

475 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
476
477 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
478 call Prepare before setting parameter values.
479
480 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
481
482 3. Code tidyup and more robust handling of dsql information result vector.
483
484 4. Support for centralised handling of transaction status changes. TIBTransaction
485 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
486 and "AfterExecQuery". The first three are called after the same event is called
487 for an IBCustomDataSet descendent using the Transaction. The fourth is called
488 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
489 enable monitoring of transaction status changes for a given transaction to be
490 handled in a single place. For example, when a change to the dataset occurs
491 an indicator can be set that shows the user that in order to save changes,
492 the transaction should be committed. Rather than doing this per dataset, this
493 can now be done per transaction.
494
495 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
496 the dataset is scrolled. However, any changes to the current row are, by default,
497 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
498 have a new property "DataSetCloseAction" that adds automatic posting of changes
499 on dataset close. If this property is set to dcDiscardChanges (default) then the
500 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
501 then IBX will attempt to post any unsaved changes before the dataset is closed
502 (and after the BeforeClose event handler is called). The exception is when the
503 dataset is being closed as a result of a transaction rollback. In this case,
504 no action is taken and any unsaved changes are discarded. This avoids both
505 unnecessary overhead and the risk that a validation error may occur in the Post
506 raising an exception and thereby preventing a rollback.
507
508 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
509 In earlier versions, the Display Width was set to the maximum byte width rather than the character
510 width. Display Widths are now corrected by dividing by the max byte width per character.
511 For UTF8 character sets, the byte width is four and hence the Display Width will be
512 the byte width divided by 4. The byte width of each character set is determined
513 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
514 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
515
516 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
517
518 8. IBLookupComboEditBox: List should now always be restored to full list when the
519 control loses focus. Default Key press default interval reduced to 200ms.
520
521 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
522 when dataset rows are less than visible rows.
523
524 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
525 does not exist or DataSet is empty. More responsive on dataset open. New event
526 OnRestorePosition. Column sort disabled if no header row.
527
528 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
529 while dataset state is dsInsert. Avoids posting errors.
530
531 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
532 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
533
534 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
535
536 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
537 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
538 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
539 always "posts" the current record regardless or whether or not it may be more appropriate
540 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
541 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
542 as the first action of the "Post" method and allows the handler to convert the Post
543 into a Cancel if that is the appropriate action on moving to a different row. This is
544 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
545 raised here, but it may still be more appropriate to validate a post and signal
546 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
547
548 15. On Unix derived systems, the Firebird library name can now be given as a colon
549 separated list. Each library name on the list is tried in turn, in left to right
550 order with the first found being used as the firebird library. By default, on Linux,
551 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
552 overidden by the FBLIB environment variable or the OnGetLibraryName function.
553
554 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
555 then it will still attempt to access the database via the Firebird Server and will
556 require a username and password. If only the pathname is given, then the username
557 and password should be omitted and the unix file permissions are used to grant
558 access.
559
560 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
561
562 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
563 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
564 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
565 corresponds to a row of the linked DataSource. Any data aware control on the
566 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
567
568 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
569 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
570 takes place during database access. This may be useful when there are performance issues with
571 the change of cursor. Setting the property to false suppresses the change of cursor.
572
573 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
574 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
575 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
576 making all changes permanent immediately rather than when the transaction is explicitly
577 committed.
578
579 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
580 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
581
582 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
583
584 Development version only.
585
586 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
587
588 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
589 This is typically used during an "OnBeforeOpen" event handler to manipulate the
590 "Where" and "Having" clauses to implement user specified filters of arbitrary
591 complexity.
592
593 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
594 three new data aware controls dependent on IBX and which make use of the SQL Parser.
595 These are:
596
597 - TIBLookupComboEditBox
598 - TIBDynamicGrid
599 - TIBTreeview
600
601 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
602 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
603 to revise the available list and restrict it to items that are prefixed by the
604 typed text (either case sensitive or case insensitive). Autoinsert allows a
605 newly typed entry to be added to the list dataset and included in the available
606 list items.
607
608 TIBDynamicGrid is a TDBGrid descendent that provides for:
609 - automatic resizing of selected columns to fill the available row length
610 - automatic positioning and sizing of a "totals" control, typically at the
611 column footer, on a per column basis.
612 - DataSet resorting on header row click, sorting the dataset by the selected column.
613 A second click on the same header cell reversed the sort order.
614 - Support for a "Panel Editor". That is on clicking the indicator column, the row
615 is automatically expanded and a panel superimposed on it. The panel can have any
616 number of child controls, typically data aware controls with the same datasource
617 as the grid allowing for editing of additional fields and more complex editors.
618 - Reselection of the same row following resorting.
619 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
620 Its properties are specified on a per column basis and allows for one or more
621 columns to have their values selected from a list provided by a dataset.
622 Autocomplete and autoinsert are also available. The existing picklist editor
623 is unaffected by the extension.
624
625 TIBTreeView is a data aware TCustomTreeView.
626
627 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
628 zero scale will no longer return an error. An Int64 will be returned instead.
629
630 4. TIBTransaction now has events for Before and After Transaction End and a new function
631 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
632
633 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
634 repeated multiple times.
635
636 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
637 check used to get in the way of using Stored Procedures, and "Update or Insert"
638 statements.
639
640 7. Insert, Modify and Delete property Editors now support Query Generation from
641 Stored Procedures.
642
643 8. Three new examples illustrate the use of the new IB Controls
644
645
646 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
647
648 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
649 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
650 Gabor Boros for reporting this problem and for testing the improvements).
651
652 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
653 See readme.field+param.names in the doc folder.
654
655 3. IBX SQL Editors will now automatically add double quotes around column names when the database
656 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
657
658 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
659
660 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
661 actions.
662
663 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
664 thanks to Yuriy Kopnin for pointing this out).
665
666 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
667
668 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
669 for both fields and parameter setting.
670
671 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
672 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
673
674 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
675 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
676
677 11. TIBTable now has a property editor for "MasterFields"
678
679 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
680 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
681
682 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
683 of settings is unrecognised. Selecting this radio button has no effect on the settings.
684
685
686 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
687
688 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
689
690 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
691
692 1. In a TIBCustomDataset descendent, a generator now only sets the value when
693 it is null. This allows for alternative user defined setting of the generator
694
695 Many thanks to Julio Jiménez for this fix
696
697 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
698 and suggests that the user may have forgotten to install it.
699
700 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
701
702 1. Conditional compilation used to limit registration of TIntegerField to
703 Lazarus versions less than 1.1
704
705 2. When a database connection is created, character set is now by default set
706 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
707 1250 to 1254.
708
709
710 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
711
712 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
713
714
715 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
716
717 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
718 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
719
720 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
721 package is changed to do this (which it should do).
722
723 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
724
725 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
726
727 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
728
729 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
730
731 4. Property editors should now correctly resize.
732
733 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
734 (restored original functionality)
735
736 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
737 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
