3     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4     changes.
5    
6 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7     Bug could result in truncated multi-byte character set values.

10 tony 49
11 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
12 tony 49 include remote system name.
13    
14     2. TIBExtract: No longer include comment header and COMMIT statement for empty
15     tables when data included in output.
16    
17     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
18     and timing information to be written to stdout. This may be used to locate
19     performance bottlenecks.
20    
21     4. SQLParser: only call "OnChanging" event handler when value is different.
22    
23     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
24    
25 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
26     that BindFields is called when the query is next activated. Avoids FieldName
27     not found error.
28

30 tony 45
31 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
32 tony 45
33 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
34    
35     3. TIBExtract: data formatted as Charset set "octets" is now output using
36     hexadecimal notation.
37    
38     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
39     using a simple XML format.
40    
41     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
42     grants to these objects.
43    
44     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
45     dependency problems restoring complex databases.
46    
47     7. TIBXScript: This component has been restructured to allow for the processing of
48     embedded XML in INSERT statements and to support interactive sources in addition
49     to non-interactive data sources such as files.
50    
51     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
52    
53     9. TIBXScript: ISQL compatiable Set statements are now supported:
54     SET SQL DIALECT
55     SET TERM
56     SET AUTODDL
57     SET BAIL
58     SET ECHO
59     SET COUNT
60     SET STATS
61     SET NAMES <character set>
62    
63     10. IBVersion unit added to hold current IBX Version Number information.
64    
65     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
66     and domain definitions.
67    
68     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
69     fully supported.
70    
71     13. TIBExtract: when a database dump includes data, the generator values are now also set.
72    
73     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
74

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

410 tony 27
411     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
412     call Prepare before setting parameter values.
413    
414     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
415    
416     3. Code tidyup and more robust handling of dsql information result vector.
417    
418     4. Support for centralised handling of transaction status changes. TIBTransaction
419     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
420     and "AfterExecQuery". The first three are called after the same event is called
421     for an IBCustomDataSet descendent using the Transaction. The fourth is called
422     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
423     enable monitoring of transaction status changes for a given transaction to be
424     handled in a single place. For example, when a change to the dataset occurs
425     an indicator can be set that shows the user that in order to save changes,
426     the transaction should be committed. Rather than doing this per dataset, this
427     can now be done per transaction.
428    
429     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
430     the dataset is scrolled. However, any changes to the current row are, by default,
431     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
432     have a new property "DataSetCloseAction" that adds automatic posting of changes
433     on dataset close. If this property is set to dcDiscardChanges (default) then the
434     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
435     then IBX will attempt to post any unsaved changes before the dataset is closed
436     (and after the BeforeClose event handler is called). The exception is when the
437     dataset is being closed as a result of a transaction rollback. In this case,
438     no action is taken and any unsaved changes are discarded. This avoids both
439     unnecessary overhead and the risk that a validation error may occur in the Post
440     raising an exception and thereby preventing a rollback.
441    
442     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
443     In earlier versions, the Display Width was set to the maximum byte width rather than the character
444     width. Display Widths are now corrected by dividing by the max byte width per character.
445     For UTF8 character sets, the byte width is four and hence the Display Width will be
446     the byte width divided by 4. The byte width of each character set is determined
447     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
448     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
449    
450     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
451    
452     8. IBLookupComboEditBox: List should now always be restored to full list when the
453     control loses focus. Default Key press default interval reduced to 200ms.
454    
455     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
456     when dataset rows are less than visible rows.
457    
458     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
459     does not exist or DataSet is empty. More responsive on dataset open. New event
460     OnRestorePosition. Column sort disabled if no header row.
461    
462     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
463     while dataset state is dsInsert. Avoids posting errors.
464    
465     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
466     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
467    
468     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
469    
470     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
471     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
472     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
473     always "posts" the current record regardless or whether or not it may be more appropriate
474     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
475     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
476     as the first action of the "Post" method and allows the handler to convert the Post
477     into a Cancel if that is the appropriate action on moving to a different row. This is
478     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
479     raised here, but it may still be more appropriate to validate a post and signal
480     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
481    
482     15. On Unix derived systems, the Firebird library name can now be given as a colon
483     separated list. Each library name on the list is tried in turn, in left to right
484     order with the first found being used as the firebird library. By default, on Linux,
485     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
486     overidden by the FBLIB environment variable or the OnGetLibraryName function.
487    
488     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
489     then it will still attempt to access the database via the Firebird Server and will
490     require a username and password. If only the pathname is given, then the username
491     and password should be omitted and the unix file permissions are used to grant
492     access.

495 tony 23
496     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
497     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
498     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
499 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
500 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
501    
502     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
503 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
504 tony 23 takes place during database access. This may be useful when there are performance issues with
505     the change of cursor. Setting the property to false suppresses the change of cursor.
506    
507     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
508     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
509     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
510     making all changes permanent immediately rather than when the transaction is explicitly
511     committed.
512    
513 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
514 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

521 tony 21
522     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
523     This is typically used during an "OnBeforeOpen" event handler to manipulate the
524     "Where" and "Having" clauses to implement user specified filters of arbitrary
525     complexity.
526    
527     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
528     three new data aware controls dependent on IBX and which make use of the SQL Parser.
529     These are:
530    
531     - TIBLookupComboEditBox
532     - TIBDynamicGrid
533     - TIBTreeview
534    
535     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
536     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
537     to revise the available list and restrict it to items that are prefixed by the
538 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
539 tony 21 newly typed entry to be added to the list dataset and included in the available
540     list items.
541    
542     TIBDynamicGrid is a TDBGrid descendent that provides for:
543     - automatic resizing of selected columns to fill the available row length
544     - automatic positioning and sizing of a "totals" control, typically at the
545     column footer, on a per column basis.
546     - DataSet resorting on header row click, sorting the dataset by the selected column.
547     A second click on the same header cell reversed the sort order.
548     - Support for a "Panel Editor". That is on clicking the indicator column, the row
549     is automatically expanded and a panel superimposed on it. The panel can have any
550     number of child controls, typically data aware controls with the same datasource
551     as the grid allowing for editing of additional fields and more complex editors.
552     - Reselection of the same row following resorting.
553     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
554     Its properties are specified on a per column basis and allows for one or more
555     columns to have their values selected from a list provided by a dataset.
556     Autocomplete and autoinsert are also available. The existing picklist editor
557     is unaffected by the extension.
558    
559     TIBTreeView is a data aware TCustomTreeView.
560    
561     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
562     zero scale will no longer return an error. An Int64 will be returned instead.
563    
564     4. TIBTransaction now has events for Before and After Transaction End and a new function
565     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
566    
567     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
568     repeated multiple times.
569    
570     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
571     check used to get in the way of using Stored Procedures, and "Update or Insert"
572     statements.
573    
574     7. Insert, Modify and Delete property Editors now support Query Generation from
575     Stored Procedures.
576    
577     8. Three new examples illustrate the use of the new IB Controls
578

581 tony 19
582     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
583     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
584     Gabor Boros for reporting this problem and for testing the improvements).
585    
586     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
587     See readme.field+param.names in the doc folder.
588    
589     3. IBX SQL Editors will now automatically add double quotes around column names when the database
590     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
591    
592     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
593    
594     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
595     actions.
596    
597     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
598     thanks to Yuriy Kopnin for pointing this out).
599    
600     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
601    
602     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
603     for both fields and parameter setting.
604    
605     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
606     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
607    
608     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
609     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
610    
611     11. TIBTable now has a property editor for "MasterFields"
612    
613     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
614     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
615    
616     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
617     of settings is unrecognised. Selecting this radio button has no effect on the settings.

626     1. In a TIBCustomDataset descendent, a generator now only sets the value when
627     it is null. This allows for alternative user defined setting of the generator
628    
629     Many thanks to Julio Jiménez for this fix
630    
631     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
632     and suggests that the user may have forgotten to install it.

636     1. Conditional compilation used to limit registration of TIntegerField to
637     Lazarus versions less than 1.1
638    
639     2. When a database connection is created, character set is now by default set
640     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
641     1250 to 1254.

651     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
652     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
653    
654     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
655     package is changed to do this (which it should do).
656    
657     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
658    
659     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
660    
661     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
662    
663     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
664    
665     4. Property editors should now correctly resize.
666    
667     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
668     (restored original functionality)
669    
670     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
671     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
