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 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
18     that BindFields is called when the query is next activated. Avoids FieldName
19     not found error.
20

22 tony 45
23 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
24 tony 45
25 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
26    
27     3. TIBExtract: data formatted as Charset set "octets" is now output using
28     hexadecimal notation.
29    
30     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
31     using a simple XML format.
32    
33     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
34     grants to these objects.
35    
36     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
37     dependency problems restoring complex databases.
38    
39     7. TIBXScript: This component has been restructured to allow for the processing of
40     embedded XML in INSERT statements and to support interactive sources in addition
41     to non-interactive data sources such as files.
42    
43     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
44    
45     9. TIBXScript: ISQL compatiable Set statements are now supported:
46     SET SQL DIALECT
47     SET TERM
48     SET AUTODDL
49     SET BAIL
50     SET ECHO
51     SET COUNT
52     SET STATS
53     SET NAMES <character set>
54    
55     10. IBVersion unit added to hold current IBX Version Number information.
56    
57     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
58     and domain definitions.
59    
60     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
61     fully supported.
62    
63     13. TIBExtract: when a database dump includes data, the generator values are now also set.
64    
65     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
66

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

401 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
402 tony 27
403     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
404     call Prepare before setting parameter values.
405    
406     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
407    
408     3. Code tidyup and more robust handling of dsql information result vector.
409    
410     4. Support for centralised handling of transaction status changes. TIBTransaction
411     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
412     and "AfterExecQuery". The first three are called after the same event is called
413     for an IBCustomDataSet descendent using the Transaction. The fourth is called
414     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
415     enable monitoring of transaction status changes for a given transaction to be
416     handled in a single place. For example, when a change to the dataset occurs
417     an indicator can be set that shows the user that in order to save changes,
418     the transaction should be committed. Rather than doing this per dataset, this
419     can now be done per transaction.
420    
421     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
422     the dataset is scrolled. However, any changes to the current row are, by default,
423     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
424     have a new property "DataSetCloseAction" that adds automatic posting of changes
425     on dataset close. If this property is set to dcDiscardChanges (default) then the
426     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
427     then IBX will attempt to post any unsaved changes before the dataset is closed
428     (and after the BeforeClose event handler is called). The exception is when the
429     dataset is being closed as a result of a transaction rollback. In this case,
430     no action is taken and any unsaved changes are discarded. This avoids both
431     unnecessary overhead and the risk that a validation error may occur in the Post
432     raising an exception and thereby preventing a rollback.
433    
434     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
435     In earlier versions, the Display Width was set to the maximum byte width rather than the character
436     width. Display Widths are now corrected by dividing by the max byte width per character.
437     For UTF8 character sets, the byte width is four and hence the Display Width will be
438     the byte width divided by 4. The byte width of each character set is determined
439     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
440     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
441    
442     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
443    
444     8. IBLookupComboEditBox: List should now always be restored to full list when the
445     control loses focus. Default Key press default interval reduced to 200ms.
446    
447     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
448     when dataset rows are less than visible rows.
449    
450     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
451     does not exist or DataSet is empty. More responsive on dataset open. New event
452     OnRestorePosition. Column sort disabled if no header row.
453    
454     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
455     while dataset state is dsInsert. Avoids posting errors.
456    
457     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
458     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
459    
460     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
461    
462     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
463     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
464     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
465     always "posts" the current record regardless or whether or not it may be more appropriate
466     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
467     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
468     as the first action of the "Post" method and allows the handler to convert the Post
469     into a Cancel if that is the appropriate action on moving to a different row. This is
470     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
471     raised here, but it may still be more appropriate to validate a post and signal
472     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
473    
474     15. On Unix derived systems, the Firebird library name can now be given as a colon
475     separated list. Each library name on the list is tried in turn, in left to right
476     order with the first found being used as the firebird library. By default, on Linux,
477     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
478     overidden by the FBLIB environment variable or the OnGetLibraryName function.
479    
480     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
481     then it will still attempt to access the database via the Firebird Server and will
482     require a username and password. If only the pathname is given, then the username
483     and password should be omitted and the unix file permissions are used to grant
484     access.

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

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

573 tony 19
574     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
575     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
576     Gabor Boros for reporting this problem and for testing the improvements).
577    
578     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
579     See readme.field+param.names in the doc folder.
580    
581     3. IBX SQL Editors will now automatically add double quotes around column names when the database
582     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
583    
584     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
585    
586     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
587     actions.
588    
589     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
590     thanks to Yuriy Kopnin for pointing this out).
591    
592     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
593    
594     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
595     for both fields and parameter setting.
596    
597     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
598     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
599    
600     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
601     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
602    
603     11. TIBTable now has a property editor for "MasterFields"
604    
605     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
606     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
607    
608     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
609     of settings is unrecognised. Selecting this radio button has no effect on the settings.

618     1. In a TIBCustomDataset descendent, a generator now only sets the value when
619     it is null. This allows for alternative user defined setting of the generator
620    
621     Many thanks to Julio Jiménez for this fix
622    
623     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
624     and suggests that the user may have forgotten to install it.

627    
628     1. Conditional compilation used to limit registration of TIntegerField to
629     Lazarus versions less than 1.1
630    
631     2. When a database connection is created, character set is now by default set
632     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
633     1250 to 1254.

643     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
644     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
645    
646     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
647     package is changed to do this (which it should do).
648    
649     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
650    
651     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
652    
653     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
654    
655     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
656    
657     4. Property editors should now correctly resize.
658    
659     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
660     (restored original functionality)
661    
662     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
663     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
