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

418 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
419     each project's source file (*.lpr).
420    
421 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
422     exists, you have to first open the package in the IDE and then close it. This
423     adds it to the most recently accessed packages list. To make it permanently
424     available, add the package name to lazarus' staticpackages.inc file.
425    
426 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.

428     7. SQL Parser can now accept quoted strings that include new lines
429    
430     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
431     of text on start of edit. This is particularly useful when tabbing to a
432     column and then inserting text.
433    
434     9. New Examples provided for IB Services and ISQLMonitor.
435    
436     10. Fix error when writing to blob streams that recorded only the last buffer
437     write in the blob stream. In most cases, this did not cause a problem as the
438     IB Blob Stream is written in a single write. However, with the TDBImage, write
439     of a graphic type prefix was lost which caused a problem when the image could
440     not be automatically recognised.
441    
442     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
443 tony 33 already open" errors due to random numbers used for the cursor name being identical.
444 tony 31
445     12. IBTable: corrected error that could result in an "Index out of bounds" error
446     when opening the table and the Primary Key is the last or only column in the
447     table. Thanks to Rick Hoover for the fix.
448    
449 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
450     of "UTF-8", and update list of available database character sets. Existing
451     users should check the current lc_ctype setting in their applications.

454    
455 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
456     empty Params property.
457    
458     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
459     Link now set up in Loaded method - avoids occasional failure to apply
460     SQL markup on initial open.
461    
462     3. "Employees" example performance improvements when scrolling.
463    
464     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
465     TFrame. Force recaching of selected frame to avoid GTK race (results in a
466     random image cached).
467    
468     5. DBControlGrid: Should now react to changes in panel height at run time.
469    
470     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
471     even when further rows exist.
472    
473     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
474     always be derived from panel height and setting this property can cause confusion.
475     Note for existing projects: to avoid a missing property error at run time,
476     each form using the DBControlGrid must be opened, updated and saved in the IDE
477     in order to remove the property value from the lfm.
478    
479    
480 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
481 tony 27
482     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
483     call Prepare before setting parameter values.
484    
485     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
486    
487     3. Code tidyup and more robust handling of dsql information result vector.
488    
489     4. Support for centralised handling of transaction status changes. TIBTransaction
490     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
491     and "AfterExecQuery". The first three are called after the same event is called
492     for an IBCustomDataSet descendent using the Transaction. The fourth is called
493     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
494     enable monitoring of transaction status changes for a given transaction to be
495     handled in a single place. For example, when a change to the dataset occurs
496     an indicator can be set that shows the user that in order to save changes,
497     the transaction should be committed. Rather than doing this per dataset, this
498     can now be done per transaction.
499    
500     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
501     the dataset is scrolled. However, any changes to the current row are, by default,
502     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
503     have a new property "DataSetCloseAction" that adds automatic posting of changes
504     on dataset close. If this property is set to dcDiscardChanges (default) then the
505     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
506     then IBX will attempt to post any unsaved changes before the dataset is closed
507     (and after the BeforeClose event handler is called). The exception is when the
508     dataset is being closed as a result of a transaction rollback. In this case,
509     no action is taken and any unsaved changes are discarded. This avoids both
510     unnecessary overhead and the risk that a validation error may occur in the Post
511     raising an exception and thereby preventing a rollback.
512    
513     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
514     In earlier versions, the Display Width was set to the maximum byte width rather than the character
515     width. Display Widths are now corrected by dividing by the max byte width per character.
516     For UTF8 character sets, the byte width is four and hence the Display Width will be
517     the byte width divided by 4. The byte width of each character set is determined
518     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
519     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
520    
521     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
522    
523     8. IBLookupComboEditBox: List should now always be restored to full list when the
524     control loses focus. Default Key press default interval reduced to 200ms.
525    
526     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
527     when dataset rows are less than visible rows.
528    
529     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
530     does not exist or DataSet is empty. More responsive on dataset open. New event
531     OnRestorePosition. Column sort disabled if no header row.
532    
533     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
534     while dataset state is dsInsert. Avoids posting errors.
535    
536     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
537     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
538    
539     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
540    
541     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
542     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
543     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
544     always "posts" the current record regardless or whether or not it may be more appropriate
545     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
546     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
547     as the first action of the "Post" method and allows the handler to convert the Post
548     into a Cancel if that is the appropriate action on moving to a different row. This is
549     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
550     raised here, but it may still be more appropriate to validate a post and signal
551     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
552    
553     15. On Unix derived systems, the Firebird library name can now be given as a colon
554     separated list. Each library name on the list is tried in turn, in left to right
555     order with the first found being used as the firebird library. By default, on Linux,
556     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
557     overidden by the FBLIB environment variable or the OnGetLibraryName function.
558    
559     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
560     then it will still attempt to access the database via the Firebird Server and will
561     require a username and password. If only the pathname is given, then the username
562     and password should be omitted and the unix file permissions are used to grant
563     access.

566 tony 23
567     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
568     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
569     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
570 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
571 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
572    
573     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
574 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
575 tony 23 takes place during database access. This may be useful when there are performance issues with
576     the change of cursor. Setting the property to false suppresses the change of cursor.
577    
578     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
579     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
580     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
581     making all changes permanent immediately rather than when the transaction is explicitly
582     committed.
583    
584 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
585 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

592 tony 21
593     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
594     This is typically used during an "OnBeforeOpen" event handler to manipulate the
595     "Where" and "Having" clauses to implement user specified filters of arbitrary
596     complexity.
597    
598     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
599     three new data aware controls dependent on IBX and which make use of the SQL Parser.
600     These are:
601    
602     - TIBLookupComboEditBox
603     - TIBDynamicGrid
604     - TIBTreeview
605    
606     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
607     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
608     to revise the available list and restrict it to items that are prefixed by the
609 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
610 tony 21 newly typed entry to be added to the list dataset and included in the available
611     list items.
612    
613     TIBDynamicGrid is a TDBGrid descendent that provides for:
614     - automatic resizing of selected columns to fill the available row length
615     - automatic positioning and sizing of a "totals" control, typically at the
616     column footer, on a per column basis.
617     - DataSet resorting on header row click, sorting the dataset by the selected column.
618     A second click on the same header cell reversed the sort order.
619     - Support for a "Panel Editor". That is on clicking the indicator column, the row
620     is automatically expanded and a panel superimposed on it. The panel can have any
621     number of child controls, typically data aware controls with the same datasource
622     as the grid allowing for editing of additional fields and more complex editors.
623     - Reselection of the same row following resorting.
624     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
625     Its properties are specified on a per column basis and allows for one or more
626     columns to have their values selected from a list provided by a dataset.
627     Autocomplete and autoinsert are also available. The existing picklist editor
628     is unaffected by the extension.
629    
630     TIBTreeView is a data aware TCustomTreeView.
631    
632     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
633     zero scale will no longer return an error. An Int64 will be returned instead.
634    
635     4. TIBTransaction now has events for Before and After Transaction End and a new function
636     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
637    
638     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
639     repeated multiple times.
640    
641     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
642     check used to get in the way of using Stored Procedures, and "Update or Insert"
643     statements.
644    
645     7. Insert, Modify and Delete property Editors now support Query Generation from
646     Stored Procedures.
647    
648     8. Three new examples illustrate the use of the new IB Controls
649

652 tony 19
653     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
654     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
655     Gabor Boros for reporting this problem and for testing the improvements).
656    
657     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
658     See readme.field+param.names in the doc folder.
659    
660     3. IBX SQL Editors will now automatically add double quotes around column names when the database
661     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
662    
663     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
664    
665     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
666     actions.
667    
668     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
669     thanks to Yuriy Kopnin for pointing this out).
670    
671     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
672    
673     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
674     for both fields and parameter setting.
675    
676     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
677     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
678    
679     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
680     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
681    
682     11. TIBTable now has a property editor for "MasterFields"
683    
684     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
685     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
686    
687     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
688     of settings is unrecognised. Selecting this radio button has no effect on the settings.

697     1. In a TIBCustomDataset descendent, a generator now only sets the value when
698     it is null. This allows for alternative user defined setting of the generator
699    
700     Many thanks to Julio Jiménez for this fix
701    
702     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
703     and suggests that the user may have forgotten to install it.

706    
707     1. Conditional compilation used to limit registration of TIntegerField to
708     Lazarus versions less than 1.1
709    
710     2. When a database connection is created, character set is now by default set
711     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
712     1250 to 1254.

722     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
723     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
724    
725     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
726     package is changed to do this (which it should do).
727    
728     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
729    
730     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
731    
732     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
733    
734     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
735    
736     4. Property editors should now correctly resize.
737    
738     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
739     (restored original functionality)
740    
741     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
742     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
