1 tony 109 IBX Change Log version (2.2-0) Tue, 16 Jan 2018 16:49:07 +0000
2 tony 101
3 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
4 tony 101
5     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
8     column values. Values returned as a result of executing an Insert or Update statement
9     replace existing values in the current row for each corresponding column.
10 tony 101
11 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
12     an automatic row refresh was performed after an insert or update query had been processed,
13     irrespective of the setting of the "ForcedUpdates" property. This has changed such
14     that an automatic refresh is no longer performed if an insert or update query contains
15     a returning clause that updates one or more fields on the current row. A full row
16     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17     field values and the select query contains read only fields. Use of Insert/update
18     returning should be significantly more efficient than excuting a refresh query.
19    
20     This behaviour change is intended to be backwards compatible and there should be no need to change
21     existing programs, other than to improve performance by using the new capability.
22    
23     3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
24     any Computed By or Identity Columns. The IBTables example has been updated to
25     illustrate the computation of the employee Full Name on update.
26    
27     4. TIBTable: The GeneratorField property is now published.
28    
29     5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
30 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
31     be inserted. A RETURNING clause is added to the insert statement to return the value of
32     each Identity column after the insert is executed.
33    
34 tony 107 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
35     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
36     Insert..Returning clause.
37 tony 104
38 tony 107 7. TIBGenerator: small performance improvement by not preparing query each time
39     a new value is generated.
40 tony 104
41 tony 107 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
42    
43     9. Property editors will now sync table name to a System Table when "Include System
44 tony 105 Tables" is selected and the query is for a System Table.
45    
46 tony 107 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
47     values are no longer converted to milliseconds from TDateTime and then back again
48     to TDateTime (the conversion to milliseconds is the default TDataset approach).
49 tony 105
50 tony 107 11. Property Editors handling of Stored Procedures.
51     * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
52     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
53     query).
54     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
55 tony 106
56 tony 107 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
57     can be used to select a package. If non-empty, the stored procedure name is
58     expected to be a stored procedure defined in the specified package and the
59     generated SQL will be as required for a stored procedure located in a package.
60    
61     13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
62     a "Package Name" drop down box to allow selection of a Firebird 3 Package from
63     which a stored procedure can be selected. With no package name selected, non-package
64     stored procedures are listed.
65    
66 tony 109 14. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
67     for password on reconnect.
68 tony 107

70 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
71 tony 56
72     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
73     changes.
74    
75 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
76     Bug could result in truncated multi-byte character set values.
77    
78 tony 60 3. Changes consequential on moving fbintf character set utility functions from
79     IFirebirdAPI to IAttachment.
80    
81 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
82    
83 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
84     results in autocomplete ignoring prefix text.
85    
86 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
87     entering a new name into the text box.
88    
89 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
90     Firebird rather than recomputing it.
91    
92 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
93     screen centre. Previously some were "poDesigned" which may be inappropriate
94     for multi monitor desktops.
95    
96 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
97    
98     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
99     a transaction and always reset the object.
100    
101     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
102    
103     13. TIBXScript: Allow for override of database filename in Create Database statements.
104    
105     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
106     to a gbak format archive.
107    
108     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
109    
110     16. IBLocaldb: Drop database if error creating an empty database.
111    
112     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
113     unless selected node not in current dataset.
114    
115     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
116     to TIBCustomService, and IBlocalDB code tidy up.
117    
118     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
119     behaviour due to uninitialised variable.
120    
121     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
122     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
123    
124     21. IBSQL: When Database changed ensure that all resources are freed.
125    
126     22. IBCustomDataset: When database changed ensure that queries an unprepared.
127    
128 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
129     * Line Wrap on SQL Token boundaries (on user command)
130     * auto-complete table names in drop down list of table names
131     * Double click on tablename or field name adds to SQL text
132 tony 80
133     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
134    
135     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
136     TVariantArray. Seems to avoid memory corruption in Windows (probably a
137     workaround for a problem in fpc 3.0.4 win64).
138    
139     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
140    
141 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
142    
143 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
144 tony 49
145 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
146 tony 49 include remote system name.
147    
148     2. TIBExtract: No longer include comment header and COMMIT statement for empty
149     tables when data included in output.
150    
151     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
152     and timing information to be written to stdout. This may be used to locate
153     performance bottlenecks.
154    
155     4. SQLParser: only call "OnChanging" event handler when value is different.
156    
157     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
158    
159 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
160     that BindFields is called when the query is next activated. Avoids FieldName
161     not found error.
162    
163 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
164     purpose and allows the programmer to define any action they want for Update, Insert
165     or Delete. This may be complex SQL (similar to a Trigger), application specific
166     filtering of updates, or use of statements such as Grant or Revoke instead of
167     normal DML. See User Manual for more information.
168    
169 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
170 tony 45
171 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
172 tony 45
173 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
174    
175     3. TIBExtract: data formatted as Charset set "octets" is now output using
176     hexadecimal notation.
177    
178     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
179     using a simple XML format.
180    
181     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
182     grants to these objects.
183    
184     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
185     dependency problems restoring complex databases.
186    
187     7. TIBXScript: This component has been restructured to allow for the processing of
188     embedded XML in INSERT statements and to support interactive sources in addition
189     to non-interactive data sources such as files.
190    
191     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
192    
193     9. TIBXScript: ISQL compatiable Set statements are now supported:
194     SET SQL DIALECT
195     SET TERM
196     SET AUTODDL
197     SET BAIL
198     SET ECHO
199     SET COUNT
200     SET STATS
201     SET NAMES <character set>
202    
203     10. IBVersion unit added to hold current IBX Version Number information.
204    
205     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
206     and domain definitions.
207    
208     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
209     fully supported.
210    
211     13. TIBExtract: when a database dump includes data, the generator values are now also set.
212    
213     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
214    
215     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
216    
217 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
218 tony 45 upgrading to IBX2.
219    
220     1. Size property of TIBStringField is now the width in characters of the field
221     and not the byte length. This applies only to multi-byte character sets such
222     as UTF8. The original approach aligned with TStringField. However, the TStringField
223     code is not recognised as a bug and hence this change to align the behaviour.
224     The TStringField change is expected in fpc 3.2.0.
225    
226     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
227     true (default) then Size property value saved in the lfm is ignored. Size is
228     always set from the dynamic information read from the database. It is unclear
229     why anyone would want to override this and set Size to false.
230    
231     3. ibxscript: should now handle correctly a Case..End statement within a procedure
232     block.
233    
234     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
235     exist when an attempt is made to connect to it (run time only) then an attempt
236     is made to create the database.
237    
238     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
239     has been successfully created as a result of a call to CreateDatabase or when
240     creating a database after it was found not to exist.
241    
242     6. DBControlGrid: a race condition could result in the wrong row image being
243     written to the cache. This has been avoided by a trip round the message
244     loop before rendering the row image.
245    
246     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
247     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
248     known to risk corrupt rendering of row images when the control is first
249     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
250     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
251    
252     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
253     a TDateEdit control located on an editor panel.
254    
255     9. TIBExtract: brought up-to-date plus many bug fixes.
256    
257     10. DBControlGrid: Removed memory leak when updating rows.
258    
259     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
260    
261 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
262    
263     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
264     when target codepage is CP_NONE. This is a workaround for
265     http://bugs.freepascal.org/view.php?id=30622.
266    
267     2. DBLog option removed from TIBStatisticalService - not supported by server
268     since Firebird 1.5.
269    
270     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
271     similar.
272    
273     4. IBCodePage: updated mapping between codepages and character id.
274    
275     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
276     Firebird. Character sets with a char width of two are not UTF16.
277    
278     6. Strings received from the database are now always transliterated into UTF8
279     regardless of the database character set or connection character set. This
280     is for compatibility with the LCL.
281    
282 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
283 tony 41
284     1. IBBlob: Defer reading of blob until read method called. This avoids having to
285     read in an entire blob just to get the size of the blob. General performance
286     improvement when opening datasets containing blobs.
287    
288     2. Clearing a Blob now sets the corresponding field's modified flag.
289    
290     3. IBLookupCombo: When not performing auto-complete, original query sort order
291     is now used.
292    
293     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
294     determined.
295    
296     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
297    
298     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
299     lazarus 1.6.0
300    
301     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
302     compilation error.
303    
304 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
305    
306     1. No character set specified for connection: when a text blob is retrieved, the
307     character set is determined by looking up the native character set using then
308     Firebird API. Otherwise a text mode blob is assumed to have the same character
309     set as the connection.
310    
311     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
312     for Login Dialog returing a change to the database path.
313    
314     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
315     to be changed from that given in the TIBDatabase/TIBServer component and for the
316     entered value to be saved on a project specific basis (design time only).
317    
318     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
319     column fieldname. If they are the same then it is acts as a look up for the KeyValue
320     Otherwise, it sets the column text to the selected ListField Value.
321    
322     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
323     column width.
324    
325     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
326     and a case insensitive search is requested.
327    
328     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
329     or column ListSource.
330    
331     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
332     unprepare) when closing and the text has not changed.
333    
334     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
335     Less likely to cause a cursor re-use error on Windows.
336    
337     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
338     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
339    
340     11. TIBTreeView: Guard against nil destination on record changed
341    
342     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
343     string type with the code page set to reflect the returned field encoding after
344     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
345     earlier versions.
346    
347     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
348     will now result in transliteration to the code page specified for the Firebird driver
349     if the assigned string has a different code page. FPC 3.0.0 onwards only.
350    
351     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
352     is ignored and the lc_ctype value, when the database is opened, is set to align with
353     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
354     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
355     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
356     the GETACP is used to determine the Windows code page.
357    
358     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
359     name used as the lc_ctype when the database was opened. Only valid while the
360     Database is connected.
361    
362     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
363     id that corresponds to the DefaultCharSetName.
364    
365 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
366    
367     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
368     path is given and database attach fails due to access permission issues on the
369     temp directory or security database, then the attach is retried with "localhost:"
370     prefixing the databasename. This should avoid problems when the database has to
371     be accessed by a local (e.g. classic) server and libfbembed is used.
372    
373     2. Windows: revised search order for Firebird DLL:
374     i. The Firebird Embedded Server in the application Directory.
375     ii. If the FIREBIRD environment variable is set then the directory this
376     points to is searched for the FB Client DLL and then then underlying
377     "bin" directory.
378     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
379     is used to locate the Firebird installation directory and the underlying
380     "bin" directory is searched for the FB Client DLL.
381     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
382     are searched for the FB Client DLL.
383     v. The PATH Environment variable is used to search for the FB Client DLL.
384     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
385    
386     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
387     See doc/readme.scriptengine and example applications.
388    
389     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
390     simplify the use of the embedded firebird server on both Linux and Windows platforms.
391     See dpc/readme.localdatabase and example applications.
392    
393     5. IBDynamicGrid: Reordering on column header click should now also work for
394     dynamic columns.
395    
396     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
397     between incrementing/decrementing the lock count and signalling the event.
398    
399 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
400    
401 tony 37 1.3.2 was never formally released and only made available as beta copies.
402    
403 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
404    
405     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
406    
407     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
408    
409     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
410     i.e. when it is a calculated field
411    
412     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
413     This problem was due to a race condition between recalculating row heights and
414     determining which row was selected by the mouse click. The row height calculation
415     is now deferred by an extra trip round the message loop allowing the row to
416     be always calculated on the current grid layout rather than risking it being
417     calculated on the grid layout after the expanded row has been shrunk.
418    
419     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
420     Windows.
421    
422     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
423     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
424 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
425 tony 35
426     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
427 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
428 tony 35
429     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
430     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
431 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
432 tony 35
433     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
434     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
435     implies no truncation.
436    
437     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
438    
439     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
440     (avoids "Not in Edit Mode" error).
441    
442     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
443    
444     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
445     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
446    
447     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
448    
449     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
450    
451     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
452    
453     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
454

456 tony 31
457     1. OnCloseUp Event Handler added to TDBLookupProperties
458    
459     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
460     problem with row size when exception is called.
461    
462     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
463    
464     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
465     in a TCustomComboBox and ignores return key if in a TCustomMemo
466    
467     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
468     keyed in i.e. when autocomplete not performed
469    
470 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
471     console mode applications with all LCL required functions (builtin dialogs and
472     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
473     not included in your project, IBX should compile and link with a console mode program.
474     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
475     console mode application or the IDE will automatically assume that your
476     application is GUI based. Instead, you should include the ibexpressconsolemode package.
477 tony 31
478     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
479     to use the built in dialogs and cursor management. IBDialogs is
480 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
481 tony 31 This should be the case for all projects created through the IDE. This is why
482     you do not want to add the ibexpress package to console mode applications. The
483     ibexpressconsolemode package has been created to allow console mode programs
484     to avoid adding LCL dependencies when using IBX, while still having the
485     unit search paths set up correctly.
486    
487 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
488     each project's source file (*.lpr).
489    
490 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
491     exists, you have to first open the package in the IDE and then close it. This
492     adds it to the most recently accessed packages list. To make it permanently
493     available, add the package name to lazarus' staticpackages.inc file.
494    
495 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
496 tony 31
497     7. SQL Parser can now accept quoted strings that include new lines
498    
499     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
500     of text on start of edit. This is particularly useful when tabbing to a
501     column and then inserting text.
502    
503     9. New Examples provided for IB Services and ISQLMonitor.
504    
505     10. Fix error when writing to blob streams that recorded only the last buffer
506     write in the blob stream. In most cases, this did not cause a problem as the
507     IB Blob Stream is written in a single write. However, with the TDBImage, write
508     of a graphic type prefix was lost which caused a problem when the image could
509     not be automatically recognised.
510    
511     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
512 tony 33 already open" errors due to random numbers used for the cursor name being identical.
513 tony 31
514     12. IBTable: corrected error that could result in an "Index out of bounds" error
515     when opening the table and the Primary Key is the last or only column in the
516     table. Thanks to Rick Hoover for the fix.
517    
518 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
519     of "UTF-8", and update list of available database character sets. Existing
520     users should check the current lc_ctype setting in their applications.
521 tony 29
522 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
523    
524 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
525     empty Params property.
526    
527     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
528     Link now set up in Loaded method - avoids occasional failure to apply
529     SQL markup on initial open.
530    
531     3. "Employees" example performance improvements when scrolling.
532    
533     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
534     TFrame. Force recaching of selected frame to avoid GTK race (results in a
535     random image cached).
536    
537     5. DBControlGrid: Should now react to changes in panel height at run time.
538    
539     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
540     even when further rows exist.
541    
542     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
543     always be derived from panel height and setting this property can cause confusion.
544     Note for existing projects: to avoid a missing property error at run time,
545     each form using the DBControlGrid must be opened, updated and saved in the IDE
546     in order to remove the property value from the lfm.
547    
548    
549 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
550 tony 27
551     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
552     call Prepare before setting parameter values.
553    
554     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
555    
556     3. Code tidyup and more robust handling of dsql information result vector.
557    
558     4. Support for centralised handling of transaction status changes. TIBTransaction
559     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
560     and "AfterExecQuery". The first three are called after the same event is called
561     for an IBCustomDataSet descendent using the Transaction. The fourth is called
562     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
563     enable monitoring of transaction status changes for a given transaction to be
564     handled in a single place. For example, when a change to the dataset occurs
565     an indicator can be set that shows the user that in order to save changes,
566     the transaction should be committed. Rather than doing this per dataset, this
567     can now be done per transaction.
568    
569     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
570     the dataset is scrolled. However, any changes to the current row are, by default,
571     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
572     have a new property "DataSetCloseAction" that adds automatic posting of changes
573     on dataset close. If this property is set to dcDiscardChanges (default) then the
574     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
575     then IBX will attempt to post any unsaved changes before the dataset is closed
576     (and after the BeforeClose event handler is called). The exception is when the
577     dataset is being closed as a result of a transaction rollback. In this case,
578     no action is taken and any unsaved changes are discarded. This avoids both
579     unnecessary overhead and the risk that a validation error may occur in the Post
580     raising an exception and thereby preventing a rollback.
581    
582     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
583     In earlier versions, the Display Width was set to the maximum byte width rather than the character
584     width. Display Widths are now corrected by dividing by the max byte width per character.
585     For UTF8 character sets, the byte width is four and hence the Display Width will be
586     the byte width divided by 4. The byte width of each character set is determined
587     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
588     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
589    
590     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
591    
592     8. IBLookupComboEditBox: List should now always be restored to full list when the
593     control loses focus. Default Key press default interval reduced to 200ms.
594    
595     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
596     when dataset rows are less than visible rows.
597    
598     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
599     does not exist or DataSet is empty. More responsive on dataset open. New event
600     OnRestorePosition. Column sort disabled if no header row.
601    
602     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
603     while dataset state is dsInsert. Avoids posting errors.
604    
605     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
606     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
607    
608     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
609    
610     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
611     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
612     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
613     always "posts" the current record regardless or whether or not it may be more appropriate
614     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
615     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
616     as the first action of the "Post" method and allows the handler to convert the Post
617     into a Cancel if that is the appropriate action on moving to a different row. This is
618     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
619     raised here, but it may still be more appropriate to validate a post and signal
620     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
621    
622     15. On Unix derived systems, the Firebird library name can now be given as a colon
623     separated list. Each library name on the list is tried in turn, in left to right
624     order with the first found being used as the firebird library. By default, on Linux,
625     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
626     overidden by the FBLIB environment variable or the OnGetLibraryName function.
627    
628     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
629     then it will still attempt to access the database via the Firebird Server and will
630     require a username and password. If only the pathname is given, then the username
631     and password should be omitted and the unix file permissions are used to grant
632     access.

635 tony 23
636     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
637     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
638     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
639 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
640 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
641    
642     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
643 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
644 tony 23 takes place during database access. This may be useful when there are performance issues with
645     the change of cursor. Setting the property to false suppresses the change of cursor.
646    
647     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
648     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
649     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
650     making all changes permanent immediately rather than when the transaction is explicitly
651     committed.
652    
653 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
654 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

661 tony 21
662     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
663     This is typically used during an "OnBeforeOpen" event handler to manipulate the
664     "Where" and "Having" clauses to implement user specified filters of arbitrary
665     complexity.
666    
667     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
668     three new data aware controls dependent on IBX and which make use of the SQL Parser.
669     These are:
670    
671     - TIBLookupComboEditBox
672     - TIBDynamicGrid
673     - TIBTreeview
674    
675     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
676     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
677     to revise the available list and restrict it to items that are prefixed by the
678 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
679 tony 21 newly typed entry to be added to the list dataset and included in the available
680     list items.
681    
682     TIBDynamicGrid is a TDBGrid descendent that provides for:
683     - automatic resizing of selected columns to fill the available row length
684     - automatic positioning and sizing of a "totals" control, typically at the
685     column footer, on a per column basis.
686     - DataSet resorting on header row click, sorting the dataset by the selected column.
687     A second click on the same header cell reversed the sort order.
688     - Support for a "Panel Editor". That is on clicking the indicator column, the row
689     is automatically expanded and a panel superimposed on it. The panel can have any
690     number of child controls, typically data aware controls with the same datasource
691     as the grid allowing for editing of additional fields and more complex editors.
692     - Reselection of the same row following resorting.
693     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
694     Its properties are specified on a per column basis and allows for one or more
695     columns to have their values selected from a list provided by a dataset.
696     Autocomplete and autoinsert are also available. The existing picklist editor
697     is unaffected by the extension.
698    
699     TIBTreeView is a data aware TCustomTreeView.
700    
701     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
702     zero scale will no longer return an error. An Int64 will be returned instead.
703    
704     4. TIBTransaction now has events for Before and After Transaction End and a new function
705     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
706    
707     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
708     repeated multiple times.
709    
710     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
711     check used to get in the way of using Stored Procedures, and "Update or Insert"
712     statements.
713    
714     7. Insert, Modify and Delete property Editors now support Query Generation from
715     Stored Procedures.
716    
717     8. Three new examples illustrate the use of the new IB Controls
718

721 tony 19
722     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
723     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
724     Gabor Boros for reporting this problem and for testing the improvements).
725    
726     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
727     See readme.field+param.names in the doc folder.
728    
729     3. IBX SQL Editors will now automatically add double quotes around column names when the database
730     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
731    
732     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
733    
734     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
735     actions.
736    
737     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
738     thanks to Yuriy Kopnin for pointing this out).
739    
740     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
741    
742     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
743     for both fields and parameter setting.
744    
745     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
746     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
747    
748     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
749     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
750    
751     11. TIBTable now has a property editor for "MasterFields"
752    
753     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
754     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
755    
756     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
757     of settings is unrecognised. Selecting this radio button has no effect on the settings.

766     1. In a TIBCustomDataset descendent, a generator now only sets the value when
767     it is null. This allows for alternative user defined setting of the generator
768    
769     Many thanks to Julio Jiménez for this fix
770    
771     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
772     and suggests that the user may have forgotten to install it.

775    
776     1. Conditional compilation used to limit registration of TIntegerField to
777     Lazarus versions less than 1.1
778    
779     2. When a database connection is created, character set is now by default set
780     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
781     1250 to 1254.

791     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
792     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
793    
794     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
795     package is changed to do this (which it should do).
796    
797     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
798    
799     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
800    
801     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
802    
803     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
804    
805     4. Property editors should now correctly resize.
806    
807     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
808     (restored original functionality)
809    
810     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
811     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
