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

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

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

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

623     1. In a TIBCustomDataset descendent, a generator now only sets the value when
624     it is null. This allows for alternative user defined setting of the generator
625    
626     Many thanks to Julio Jiménez for this fix
627    
628     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
629     and suggests that the user may have forgotten to install it.

633     1. Conditional compilation used to limit registration of TIntegerField to
634     Lazarus versions less than 1.1
635    
636     2. When a database connection is created, character set is now by default set
637     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
638     1250 to 1254.

648     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
649     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
650    
651     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
652     package is changed to do this (which it should do).
653

655    
656     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
657    
658     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
659    
660     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
661    
662     4. Property editors should now correctly resize.
663    
664     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
665     (restored original functionality)
666    
667     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
668     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
