# Line 1 | Line 1
1 + IBX Change Log  version                                   (2.1-1) Fri, 12 Jan 2018 10:13:29 +0000
2 +
3 + 1. IBExtract: Identity columns - add addition check for null column for generator name.
4 +
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 +   information). Values returned as a result of executing an Insert or Update statement
8 +   replace existing values in the current row for each corresponding column.
9 +
10 + 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 +   each Identity column after the insert is executed.
14 +
15 + 4. TIBGenerator: small performance improvement by not preparing query each time
16 +   a new number is generated.
17 +
18 + 5. TIBSQL: Free resources when transaction changed.
19 +
20 + 6. Property editor will now sync table name to a System Table when "Include System
21 +   Tables" is selected and the query is for a System Table.
22 +
23 + 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
24 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
25 +   Insert..Returning clause.
26 +
27 + 8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28 +   values are no longer converted to milliseconds from TDateTime and then back again
29 +   the TDateTime (the TDataset approach).
30 +
31 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
32 +
33 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
34 +   changes.
35 +
36 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
37 +   Bug could result in truncated multi-byte character set values.
38 +
39 + 3. Changes consequential on moving fbintf character set utility functions from
40 +   IFirebirdAPI to IAttachment.
41 +
42 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
43 +
44 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
45 +   results in autocomplete ignoring prefix text.
46 +
47 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
48 +   entering a new name into the text box.
49 +
50 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
51 +   Firebird rather than recomputing it.
52 +
53 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
54 +   screen centre. Previously some were "poDesigned" which may be inappropriate
55 +   for multi monitor desktops.
56 +
57 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
58 +
59 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
60 +    a transaction and always reset the object.
61 +
62 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
63 +
64 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
65 +
66 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
67 +    to a gbak format archive.
68 +
69 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
70 +
71 + 16. IBLocaldb: Drop database if error creating an empty database.
72 +
73 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
74 +    unless selected node not in current dataset.
75 +
76 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
77 +    to TIBCustomService, and IBlocalDB code tidy up.
78 +
79 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
80 +    behaviour due to uninitialised variable.
81 +
82 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
83 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
84 +
85 + 21. IBSQL: When Database changed ensure that all resources are freed.
86 +
87 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
88 +
89 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
90 +    * Line Wrap on SQL Token boundaries (on user command)
91 +    * auto-complete table names in drop down list of table names
92 +    * Double click on tablename or field name adds to SQL text
93 +
94 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
95 +
96 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
97 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
98 +    workaround for a problem in fpc 3.0.4 win64).
99 +
100 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
101 +
102 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
103 +
104 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
105 +
106 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
107 +   include remote system name.
108 +
109 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
110 +   tables when data included in output.
111 +
112 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
113 +   and timing information to be written to stdout. This may be used to locate
114 +   performance bottlenecks.
115 +
116 + 4. SQLParser: only call "OnChanging" event handler when value is different.
117 +
118 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
119 +
120 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
121 +   that BindFields is called when the query is next activated. Avoids FieldName
122 +   not found error.
123 +
124 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
125 +   purpose and allows the programmer to define any action they want for Update, Insert
126 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
127 +   filtering of updates, or use of statements such as Grant or Revoke instead of
128 +   normal DML. See User Manual for more information.
129 +
130 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
131 +
132 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
133 +
134 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
135 +
136 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
137 +   hexadecimal notation.
138 +
139 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
140 +   using a simple XML format.
141 +
142 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
143 +   grants to these objects.
144 +
145 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
146 +   dependency problems restoring complex databases.
147 +
148 + 7. TIBXScript: This component has been restructured to allow for the processing of
149 +   embedded XML in INSERT statements and to support interactive sources in addition
150 +   to non-interactive data sources such as files.
151 +
152 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
153 +
154 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
155 +   SET SQL DIALECT
156 +   SET TERM
157 +   SET AUTODDL
158 +   SET BAIL
159 +   SET ECHO
160 +   SET COUNT
161 +   SET STATS
162 +   SET NAMES <character set>
163 +
164 + 10. IBVersion unit added to hold current IBX Version Number information.
165 +
166 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
167 +    and domain definitions.
168 +
169 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
170 +    fully supported.
171 +
172 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
173 +
174 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
175 +
176 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
177 +
178 + See also doc/IBX4LazarusGuide.pdf for important information on
179 + upgrading to IBX2.
180 +
181 + 1. Size property of TIBStringField is now the width in characters of the field
182 +   and not the byte length. This applies only to multi-byte character sets such
183 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
184 +   code is not recognised as a bug and hence this change to align the behaviour.
185 +   The TStringField change is expected in fpc 3.2.0.
186 +
187 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
188 +   true (default) then Size property value saved in the lfm is ignored. Size is
189 +   always set from the dynamic information read from the database. It is unclear
190 +   why anyone would want to override this and set Size to false.
191 +
192 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
193 +   block.
194 +
195 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
196 +   exist when an attempt is made to connect to it (run time only) then an attempt
197 +   is made to create the database.
198 +
199 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
200 +   has been successfully created as a result of a call to CreateDatabase or when
201 +   creating a database after it was found not to exist.
202 +
203 + 6.  DBControlGrid: a race condition could result in the wrong row image being
204 +    written to the cache. This has been avoided by a trip round the message
205 +    loop before rendering the row image.
206 +
207 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
208 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
209 +    known to risk corrupt rendering of row images when the control is first
210 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
211 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
212 +
213 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
214 +    a TDateEdit control located on an editor panel.
215 +
216 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
217 +
218 + 10. DBControlGrid: Removed memory leak when updating rows.
219 +
220 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
221 +
222 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
223 +
224 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
225 +   when target codepage is CP_NONE. This is a workaround for
226 +   http://bugs.freepascal.org/view.php?id=30622.
227 +
228 + 2. DBLog option removed from TIBStatisticalService - not supported by server
229 +   since Firebird 1.5.
230 +
231 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
232 +   similar.
233 +
234 + 4. IBCodePage: updated mapping between codepages and character id.
235 +
236 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
237 +   Firebird. Character sets with a char width of two are not UTF16.
238 +
239 + 6. Strings received from the database are now always transliterated into UTF8
240 +   regardless of the database character set or connection character set. This
241 +   is for compatibility with the LCL.
242 +
243 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
244 +
245 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
246 +   read in an entire blob just to get the size of the blob. General performance
247 +   improvement when opening datasets containing blobs.
248 +
249 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
250 +
251 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
252 +   is now used.
253 +
254 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
255 +   determined.
256 +
257 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
258 +
259 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
260 +   lazarus 1.6.0
261 +
262 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
263 +   compilation error.
264 +
265 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
266 +
267 + 1. No character set specified for connection: when a text blob is retrieved, the
268 +  character set is determined by looking up the native character set using then
269 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
270 +  set as the connection.
271 +
272 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
273 +   for Login Dialog returing a change to the database path.
274 +
275 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
276 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
277 +   entered value to be saved on a project specific basis (design time only).
278 +
279 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
280 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
281 +   Otherwise, it sets the column text to the selected ListField Value.
282 +
283 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
284 +   column width.
285 +
286 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
287 +   and a case insensitive search is requested.
288 +
289 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
290 +   or column ListSource.
291 +
292 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
293 +   unprepare) when closing and the text has not changed.
294 +
295 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
296 +   Less likely to cause a cursor re-use error on Windows.
297 +
298 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
299 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
300 +
301 + 11. TIBTreeView: Guard against nil destination on record changed
302 +
303 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
304 +    string type with the code page set to reflect the returned field encoding after
305 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
306 +    earlier versions.
307 +
308 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
309 +    will now result in transliteration to the code page specified for the Firebird driver
310 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
311 +
312 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
313 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
314 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
315 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
316 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
317 +    the GETACP is used to determine the Windows code page.
318 +
319 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
320 +    name used as the lc_ctype when the database was opened. Only valid while the
321 +    Database is connected.
322 +
323 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
324 +    id that corresponds to the DefaultCharSetName.
325 +
326 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
327 +
328 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
329 +   path is given and database attach fails due to access permission issues on the
330 +   temp directory or security database, then the attach is retried with "localhost:"
331 +   prefixing the databasename. This should avoid problems when the database has to
332 +   be accessed by a local (e.g. classic) server and libfbembed is used.
333 +
334 + 2. Windows: revised search order for Firebird DLL:
335 +     i.   The Firebird Embedded Server in the application Directory.
336 +     ii.  If the FIREBIRD environment variable is set then the directory this
337 +          points to is searched for the FB Client DLL and then then underlying
338 +          "bin" directory.
339 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
340 +          is used to locate the Firebird installation directory and the underlying
341 +          "bin" directory is searched for the FB Client DLL.
342 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
343 +          are searched for the FB Client DLL.
344 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
345 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
346 +
347 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
348 +   See doc/readme.scriptengine and example applications.
349 +
350 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
351 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
352 +   See dpc/readme.localdatabase and example applications.
353 +
354 + 5. IBDynamicGrid: Reordering on column header click should now also work for
355 +   dynamic columns.
356 +
357 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
358 +   between incrementing/decrementing the lock count and signalling the event.
359 +
360 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
361 +
362 + 1.3.2 was never formally released and only made available as beta copies.
363 +
364 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
365 +
366 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
367 +
368 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
369 +
370 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
371 +   i.e. when it is a calculated field
372 +
373 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
374 +   This problem was due to a race condition between recalculating row heights and
375 +   determining which row was selected by the mouse click. The row height calculation
376 +   is now deferred by an extra trip round the message loop allowing the row to
377 +   be always calculated on the current grid layout rather than risking it being
378 +   calculated on the grid layout after the expanded row has been shrunk.
379 +
380 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
381 +   Windows.
382 +
383 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
384 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
385 +   to be determined at runtime. See doc/readme.charactersets.html.
386 +
387 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
388 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
389 +
390 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
391 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
392 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
393 +
394 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
395 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
396 +   implies no truncation.
397 +
398 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
399 +
400 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
401 +   (avoids "Not in Edit Mode" error).
402 +
403 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
404 +
405 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
406 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
407 +
408 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
409 +
410 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
411 +
412 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
413 +
414 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
415 +
