73 >
74 > See also doc/IBX4LazarusGuide.pdf for important information on
75 > upgrading to IBX2.
76 >
77 > 1. Size property of TIBStringField is now the width in characters of the field
78 >   and not the byte length. This applies only to multi-byte character sets such
79 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
80 >   code is not recognised as a bug and hence this change to align the behaviour.
81 >   The TStringField change is expected in fpc 3.2.0.
82 >
83 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
84 >   true (default) then Size property value saved in the lfm is ignored. Size is
85 >   always set from the dynamic information read from the database. It is unclear
86 >   why anyone would want to override this and set Size to false.
87 >
88 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
89 >   block.
90 >
91 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
92 >   exist when an attempt is made to connect to it (run time only) then an attempt
93 >   is made to create the database.
94 >
95 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
96 >   has been successfully created as a result of a call to CreateDatabase or when
97 >   creating a database after it was found not to exist.
98 >
99 > 6.  DBControlGrid: a race condition could result in the wrong row image being
100 >    written to the cache. This has been avoided by a trip round the message
101 >    loop before rendering the row image.
102 >
103 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
104 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
105 >    known to risk corrupt rendering of row images when the control is first
106 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
107 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
108 >
109 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
110 >    a TDateEdit control located on an editor panel.
111 >
112 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
113 >
114 > 10. DBControlGrid: Removed memory leak when updating rows.
115 >
116 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

119 >
120 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
121 >   when target codepage is CP_NONE. This is a workaround for
122 >   http://bugs.freepascal.org/view.php?id=30622.
123 >
124 > 2. DBLog option removed from TIBStatisticalService - not supported by server
125 >   since Firebird 1.5.
126 >
127 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
128 >   similar.
129 >
130 > 4. IBCodePage: updated mapping between codepages and character id.
131 >
132 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
133 >   Firebird. Character sets with a char width of two are not UTF16.
134 >
135 > 6. Strings received from the database are now always transliterated into UTF8
136 >   regardless of the database character set or connection character set. This
137 >   is for compatibility with the LCL.
138 >
139 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
140 >
141 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
142 >   read in an entire blob just to get the size of the blob. General performance
143 >   improvement when opening datasets containing blobs.
144 >
145 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
146 >
147 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
148 >   is now used.
149 >
150 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
151 >   determined.
152 >
153 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
154 >
155 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
156 >   lazarus 1.6.0
157 >
158 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
159 >   compilation error.
160 >
161 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
162 >
163 > 1. No character set specified for connection: when a text blob is retrieved, the
164 >  character set is determined by looking up the native character set using then
165 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
166 >  set as the connection.
167 >
168 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
169 >   for Login Dialog returing a change to the database path.
170 >
171 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
172 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
173 >   entered value to be saved on a project specific basis (design time only).
174 >
175 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
176 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
177 >   Otherwise, it sets the column text to the selected ListField Value.
178 >
179 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
180 >   column width.
181 >
182 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
183 >   and a case insensitive search is requested.
184 >
185 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
186 >   or column ListSource.
187 >
188 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
189 >   unprepare) when closing and the text has not changed.
190 >
191 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
192 >   Less likely to cause a cursor re-use error on Windows.
193 >
194 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
195 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
196 >
197 > 11. TIBTreeView: Guard against nil destination on record changed
198 >
199 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
200 >    string type with the code page set to reflect the returned field encoding after
201 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
202 >    earlier versions.
203 >
204 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
205 >    will now result in transliteration to the code page specified for the Firebird driver
206 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
207 >
208 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
209 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
210 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
211 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
212 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
213 >    the GETACP is used to determine the Windows code page.
214 >
215 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
216 >    name used as the lc_ctype when the database was opened. Only valid while the
217 >    Database is connected.
218 >
219 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
220 >    id that corresponds to the DefaultCharSetName.

223 >
224 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
225 >   path is given and database attach fails due to access permission issues on the
226 >   temp directory or security database, then the attach is retried with "localhost:"
227 >   prefixing the databasename. This should avoid problems when the database has to
228 >   be accessed by a local (e.g. classic) server and libfbembed is used.
229 >
230 > 2. Windows: revised search order for Firebird DLL:
231 >     i.   The Firebird Embedded Server in the application Directory.
232 >     ii.  If the FIREBIRD environment variable is set then the directory this
233 >          points to is searched for the FB Client DLL and then then underlying
234 >          "bin" directory.
235 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
236 >          is used to locate the Firebird installation directory and the underlying
237 >          "bin" directory is searched for the FB Client DLL.
238 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
239 >          are searched for the FB Client DLL.
240 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
241 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
242 >
243 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
244 >   See doc/readme.scriptengine and example applications.
245 >
246 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
247 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
248 >   See dpc/readme.localdatabase and example applications.
249 >
250 > 5. IBDynamicGrid: Reordering on column header click should now also work for
251 >   dynamic columns.
252 >
253 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
254 >   between incrementing/decrementing the lock count and signalling the event.

256 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
257 >
258 > 1.3.2 was never formally released and only made available as beta copies.
259 >
260 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
261 >
262 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
263 >
264 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
265 >
266 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
267 >   i.e. when it is a calculated field
268 >
269 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
270 >   This problem was due to a race condition between recalculating row heights and
271 >   determining which row was selected by the mouse click. The row height calculation
272 >   is now deferred by an extra trip round the message loop allowing the row to
273 >   be always calculated on the current grid layout rather than risking it being
274 >   calculated on the grid layout after the expanded row has been shrunk.
275 >
276 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
277 >   Windows.
278 >
279 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
280 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
281 >   to be determined at runtime. See doc/readme.charactersets.html.
282 >
283 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
284 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
285 >
286 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
287 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
288 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
289 >
290 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
291 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
292 >   implies no truncation.
293 >
294 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
295 >
296 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
297 >   (avoids "Not in Edit Mode" error).
298 >
299 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
300 >
301 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
302 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
303 >
304 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
305 >
306 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
307 >
308 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
309 >
310 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

334  
335       IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
336       to use the built in dialogs and cursor management. IBDialogs is
337 <     included by default if "ibexpress" is in your project source "uses" clause.
337 >     included by default if "ibexpress" is in your project source's "uses" clause.
338       This should be the case for all projects created through the IDE. This is why
339       you do not want to add the ibexpress package to console mode applications. The
340       ibexpressconsolemode package has been created to allow console mode programs
341       to avoid adding LCL dependencies when using IBX, while still having the
342       unit search paths set up correctly.
343  
344 +     Existing users should check to ensure that the "ibexpress" unit is included in
345 +     each project's source file (*.lpr).
346 +
347       You may find that in order for the IDE to recognise that ibexpressconsolemode
348       exists, you have to first open the package in the IDE and then close it. This
349       adds it to the most recently accessed packages list. To make it permanently
350       available, add the package name to lazarus' staticpackages.inc file.
351  
352 <     Under Windows, the TISQLMonitor OnSQL Event Handler may require a new call to
39 <         Application.ProcessMessages in order to display an event journal correctly. See
40 <         example. This was previously called by TISQLMonitor itself but removed to avoid
41 <         a GUI dependency.
42 <
43 <         Thansk to Julio Jiménez for suggesting support of console mode.
352 >         Thanks to Julio Jiménez for suggesting support of console mode.
353  
354   7.   SQL Parser can now accept quoted strings that include new lines

367  
368   11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
369 <    already open" errors due to random numbers being identical.
369 >    already open" errors due to random numbers used for the cursor name being identical.
370  
371   12. IBTable: corrected error that could result in an "Index out of bounds" error
372      when opening the table and the Primary Key is the last or only column in the
373      table. Thanks to Rick Hoover for the fix.

492  
493   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
494      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
# Line 197 | Line 510 | IBX Change Log  version
510   4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
