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

483 tony 23
484     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
485     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
486     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
487 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
488 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
489    
490     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
491 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
492 tony 23 takes place during database access. This may be useful when there are performance issues with
493     the change of cursor. Setting the property to false suppresses the change of cursor.
494    
495     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
496     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
497     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
498     making all changes permanent immediately rather than when the transaction is explicitly
499     committed.
500    
501 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
502 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

509 tony 21
510     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
511     This is typically used during an "OnBeforeOpen" event handler to manipulate the
512     "Where" and "Having" clauses to implement user specified filters of arbitrary
513     complexity.
514    
515     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
516     three new data aware controls dependent on IBX and which make use of the SQL Parser.
517     These are:
518    
519     - TIBLookupComboEditBox
520     - TIBDynamicGrid
521     - TIBTreeview
522    
523     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
524     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
525     to revise the available list and restrict it to items that are prefixed by the
526 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
527 tony 21 newly typed entry to be added to the list dataset and included in the available
528     list items.
529    
530     TIBDynamicGrid is a TDBGrid descendent that provides for:
531     - automatic resizing of selected columns to fill the available row length
532     - automatic positioning and sizing of a "totals" control, typically at the
533     column footer, on a per column basis.
534     - DataSet resorting on header row click, sorting the dataset by the selected column.
535     A second click on the same header cell reversed the sort order.
536     - Support for a "Panel Editor". That is on clicking the indicator column, the row
537     is automatically expanded and a panel superimposed on it. The panel can have any
538     number of child controls, typically data aware controls with the same datasource
539     as the grid allowing for editing of additional fields and more complex editors.
540     - Reselection of the same row following resorting.
541     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
542     Its properties are specified on a per column basis and allows for one or more
543     columns to have their values selected from a list provided by a dataset.
544     Autocomplete and autoinsert are also available. The existing picklist editor
545     is unaffected by the extension.
546    
547     TIBTreeView is a data aware TCustomTreeView.
548    
549     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
550     zero scale will no longer return an error. An Int64 will be returned instead.
551    
552     4. TIBTransaction now has events for Before and After Transaction End and a new function
553     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
554    
555     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
556     repeated multiple times.
557    
558     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
559     check used to get in the way of using Stored Procedures, and "Update or Insert"
560     statements.
561    
562     7. Insert, Modify and Delete property Editors now support Query Generation from
563     Stored Procedures.
564    
565     8. Three new examples illustrate the use of the new IB Controls
566

570     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
571     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
572     Gabor Boros for reporting this problem and for testing the improvements).
573    
574     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
575     See readme.field+param.names in the doc folder.
576    
577     3. IBX SQL Editors will now automatically add double quotes around column names when the database
578     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
579    
580     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
581    
582     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
583     actions.
584    
585     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
586     thanks to Yuriy Kopnin for pointing this out).
587    
588     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
589    
590     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
591     for both fields and parameter setting.
592    
593     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
594     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
595    
596     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
597     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
598    
599     11. TIBTable now has a property editor for "MasterFields"
600    
601     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
602     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
603    
604     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
605     of settings is unrecognised. Selecting this radio button has no effect on the settings.

614     1. In a TIBCustomDataset descendent, a generator now only sets the value when
615     it is null. This allows for alternative user defined setting of the generator
616    
617     Many thanks to Julio Jiménez for this fix
618    
619     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
620     and suggests that the user may have forgotten to install it.

624     1. Conditional compilation used to limit registration of TIntegerField to
625     Lazarus versions less than 1.1
626    
627     2. When a database connection is created, character set is now by default set
628     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
629     1250 to 1254.

639     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
640     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
641    
642     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
643     package is changed to do this (which it should do).
644    
645     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
646    
647     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
648    
649     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
650    
651     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
652    
653     4. Property editors should now correctly resize.
654    
655     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
656     (restored original functionality)
657    
658     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
659     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
