2 >
3 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 >   changes.
5 >
6 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 >   Bug could result in truncated multi-byte character set values.
8 >
9 > 3. Changes consequential on moving fbintf character set utility functions from
10 >   IFirebirdAPI to IAttachment.
11 >
12 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
13 >
14 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 >   results in autocomplete ignoring prefix text.
16 >
17 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 >   entering a new name into the text box.
19 >
20 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21 >   Firebird rather than recomputing it.

24 >
25 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
26 >   include remote system name.
27 >
28 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
29 >   tables when data included in output.
30 >
31 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
32 >   and timing information to be written to stdout. This may be used to locate
33 >   performance bottlenecks.

36 >
37 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
38 >
39 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
40 >   that BindFields is called when the query is next activated. Avoids FieldName
41 >   not found error.

54 >
55 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
56 >   grants to these objects.
57 >
58 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
59 >   dependency problems restoring complex databases.
60 >
61 > 7. TIBXScript: This component has been restructured to allow for the processing of
62 >   embedded XML in INSERT statements and to support interactive sources in addition
63 >   to non-interactive data sources such as files.
64 >
65 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.

87 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
88 >
89 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
90 >
91 > See also doc/IBX4LazarusGuide.pdf for important information on
92 > upgrading to IBX2.
93 >
94 > 1. Size property of TIBStringField is now the width in characters of the field
95 >   and not the byte length. This applies only to multi-byte character sets such
96 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
97 >   code is not recognised as a bug and hence this change to align the behaviour.
98 >   The TStringField change is expected in fpc 3.2.0.
99 >
100 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
101 >   true (default) then Size property value saved in the lfm is ignored. Size is
102 >   always set from the dynamic information read from the database. It is unclear
103 >   why anyone would want to override this and set Size to false.
104 >
105 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
106 >   block.
107 >
108 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
109 >   exist when an attempt is made to connect to it (run time only) then an attempt
110 >   is made to create the database.
111 >
112 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
113 >   has been successfully created as a result of a call to CreateDatabase or when
114 >   creating a database after it was found not to exist.
115 >
116 > 6.  DBControlGrid: a race condition could result in the wrong row image being
117 >    written to the cache. This has been avoided by a trip round the message
118 >    loop before rendering the row image.
119 >
120 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
121 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
122 >    known to risk corrupt rendering of row images when the control is first
123 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
124 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
125 >
126 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
127 >    a TDateEdit control located on an editor panel.
128 >
129 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
130 >
131 > 10. DBControlGrid: Removed memory leak when updating rows.
132 >
133 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
134 >
135 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
136 >
137 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
138 >   when target codepage is CP_NONE. This is a workaround for
139 >   http://bugs.freepascal.org/view.php?id=30622.
140 >
141 > 2. DBLog option removed from TIBStatisticalService - not supported by server
142 >   since Firebird 1.5.
143 >
144 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
145 >   similar.
146 >
147 > 4. IBCodePage: updated mapping between codepages and character id.
148 >
149 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
150 >   Firebird. Character sets with a char width of two are not UTF16.
151 >
152 > 6. Strings received from the database are now always transliterated into UTF8
153 >   regardless of the database character set or connection character set. This
154 >   is for compatibility with the LCL.
155 >
156 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
157 >
158 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
159 >   read in an entire blob just to get the size of the blob. General performance
160 >   improvement when opening datasets containing blobs.
161 >
162 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
163 >
164 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
165 >   is now used.
166 >
167 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
168 >   determined.
169 >
170 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
171 >
172 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
173 >   lazarus 1.6.0
174 >
175 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
176 >   compilation error.
177 >
178 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
179 >
180 > 1. No character set specified for connection: when a text blob is retrieved, the
181 >  character set is determined by looking up the native character set using then
182 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
183 >  set as the connection.
184 >
185 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
186 >   for Login Dialog returing a change to the database path.
187 >
188 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
189 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
190 >   entered value to be saved on a project specific basis (design time only).
191 >
192 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
193 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
194 >   Otherwise, it sets the column text to the selected ListField Value.
195 >
196 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
197 >   column width.
198 >
199 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
200 >   and a case insensitive search is requested.
201 >
202 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
203 >   or column ListSource.
204 >
205 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
206 >   unprepare) when closing and the text has not changed.
207 >
208 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
209 >   Less likely to cause a cursor re-use error on Windows.
210 >
211 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
212 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
213 >
214 > 11. TIBTreeView: Guard against nil destination on record changed
215 >
216 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
217 >    string type with the code page set to reflect the returned field encoding after
218 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
219 >    earlier versions.
220 >
221 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
222 >    will now result in transliteration to the code page specified for the Firebird driver
223 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
224 >
225 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
226 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
227 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
228 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
229 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
230 >    the GETACP is used to determine the Windows code page.
231 >
232 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
233 >    name used as the lc_ctype when the database was opened. Only valid while the
234 >    Database is connected.
235 >
236 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
237 >    id that corresponds to the DefaultCharSetName.
238 >
239 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
240 >
241 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
242 >   path is given and database attach fails due to access permission issues on the
243 >   temp directory or security database, then the attach is retried with "localhost:"
244 >   prefixing the databasename. This should avoid problems when the database has to
245 >   be accessed by a local (e.g. classic) server and libfbembed is used.
246 >
247 > 2. Windows: revised search order for Firebird DLL:
248 >     i.   The Firebird Embedded Server in the application Directory.
249 >     ii.  If the FIREBIRD environment variable is set then the directory this
250 >          points to is searched for the FB Client DLL and then then underlying
251 >          "bin" directory.
252 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
253 >          is used to locate the Firebird installation directory and the underlying
254 >          "bin" directory is searched for the FB Client DLL.
255 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
256 >          are searched for the FB Client DLL.
257 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
258 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
259 >
260 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
261 >   See doc/readme.scriptengine and example applications.
262 >
263 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
264 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
265 >   See dpc/readme.localdatabase and example applications.
266 >
267 > 5. IBDynamicGrid: Reordering on column header click should now also work for
268 >   dynamic columns.
269 >
270 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
271 >   between incrementing/decrementing the lock count and signalling the event.
272 >
273 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
274 >
275 > 1.3.2 was never formally released and only made available as beta copies.
276 >
277 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
278 >
279 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
280 >
281 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
282 >
283 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
284 >   i.e. when it is a calculated field
285 >
286 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
287 >   This problem was due to a race condition between recalculating row heights and
288 >   determining which row was selected by the mouse click. The row height calculation
289 >   is now deferred by an extra trip round the message loop allowing the row to
290 >   be always calculated on the current grid layout rather than risking it being
291 >   calculated on the grid layout after the expanded row has been shrunk.
292 >
293 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
294 >   Windows.
295 >
296 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
297 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
298 >   to be determined at runtime. See doc/readme.charactersets.html.
299 >
300 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
301 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
302 >
303 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
304 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
305 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
306 >
307 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
308 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
309 >   implies no truncation.
310 >
311 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
312 >
313 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
314 >   (avoids "Not in Edit Mode" error).
315 >
316 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
317 >
318 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
319 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
320 >
321 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
322 >
323 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
324 >
325 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
326 >
327 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
328 >
329 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
330 >
331 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
332 >
333 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
334 >     problem with row size when exception is called.
335 >
336 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
337 >
338 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
339 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
340 >
341 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
342 >     keyed in i.e. when autocomplete not performed
343 >
344 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
345 >     console mode applications with all LCL required functions (builtin dialogs and
346 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
347 >     not included in your project, IBX should compile and link with a console mode program.
348 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
349 >     console mode application or the IDE will automatically assume that your
350 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
351 >
352 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
353 >     to use the built in dialogs and cursor management. IBDialogs is
354 >     included by default if "ibexpress" is in your project source's "uses" clause.
355 >     This should be the case for all projects created through the IDE. This is why
356 >     you do not want to add the ibexpress package to console mode applications. The
357 >     ibexpressconsolemode package has been created to allow console mode programs
358 >     to avoid adding LCL dependencies when using IBX, while still having the
359 >     unit search paths set up correctly.
360 >
361 >     Existing users should check to ensure that the "ibexpress" unit is included in
362 >     each project's source file (*.lpr).
363 >
364 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
365 >     exists, you have to first open the package in the IDE and then close it. This
366 >     adds it to the most recently accessed packages list. To make it permanently
367 >     available, add the package name to lazarus' staticpackages.inc file.
368 >
369 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
370 >
371 > 7.   SQL Parser can now accept quoted strings that include new lines
372 >
373 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
374 >     of text on start of edit. This is particularly useful when tabbing to a
375 >     column and then inserting text.
376 >
377 > 9.   New Examples provided for IB Services and ISQLMonitor.
378 >
379 > 10. Fix error when writing to blob streams that recorded only the last buffer
380 >    write in the blob stream. In most cases, this did not cause a problem as the
381 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
382 >    of a graphic type prefix was lost which caused a problem when the image could
383 >        not be automatically recognised.
384 >
385 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
386 >    already open" errors due to random numbers used for the cursor name being identical.
387 >
388 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
389 >    when opening the table and the Primary Key is the last or only column in the
390 >    table. Thanks to Rick Hoover for the fix.
391 >
392 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
393 >    of "UTF-8", and update list of available database character sets. Existing
394 >    users should check the current lc_ctype setting in their applications.
