18 >
19 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
20 >
21 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
22 >
23 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
24 >   hexadecimal notation.
25 >
26 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements

28 >
29 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
30 >   grants to these objects.
31 >
32 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
33 >   dependency problems restoring complex databases.
34 >
35 > 7. TIBXScript: This component has been restructured to allow for the processing of
36 >   embedded XML in INSERT statements and to support interactive sources in addition
37 >   to non-interactive data sources such as files.
38 >
39 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
40 >
41 > 9. TIBXScript: ISQL compatiable Set statements are now supported:

44 >   SET AUTODDL
45 >   SET BAIL
46 >   SET ECHO
47 >   SET COUNT
48 >   SET STATS
49 >   SET NAMES <character set>
50 >
51 > 10. IBVersion unit added to hold current IBX Version Number information.

57 >    fully supported.
58 >
59 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
60 >
61 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
62 >
63 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
64 >
65 > See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
66 > upgrading to IBX2.
67 >
68 > 1. Size property of TIBStringField is now the width in characters of the field
69 >   and not the byte length. This applies only to multi-byte character sets such
70 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
71 >   code is not recognised as a bug and hence this change to align the behaviour.
72 >   The TStringField change is expected in fpc 3.2.0.
73 >
74 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
75 >   true (default) then Size property value saved in the lfm is ignored. Size is
76 >   always set from the dynamic information read from the database. It is unclear
77 >   why anyone would want to override this and set Size to false.
78 >
79 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
80 >   block.
81 >
82 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
83 >   exist when an attempt is made to connect to it (run time only) then an attempt
84 >   is made to create the database.
85 >
86 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
87 >   has been successfully created as a result of a call to CreateDatabase or when
88 >   creating a database after it was found not to exist.
89 >
90 > 6.  DBControlGrid: a race condition could result in the wrong row image being
91 >    written to the cache. This has been avoided by a trip round the message
92 >    loop before rendering the row image.
93 >
94 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
95 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
96 >    known to risk corrupt rendering of row images when the control is first
97 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
98 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
99 >
100 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
101 >    a TDateEdit control located on an editor panel.
102 >
103 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
104 >
105 > 10. DBControlGrid: Removed memory leak when updating rows.
106 >
107 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
108 >
109 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
110 >
111 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
112 >   when target codepage is CP_NONE. This is a workaround for
113 >   http://bugs.freepascal.org/view.php?id=30622.
114 >
115 > 2. DBLog option removed from TIBStatisticalService - not supported by server
116 >   since Firebird 1.5.
117 >
118 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
119 >   similar.
120 >
121 > 4. IBCodePage: updated mapping between codepages and character id.
122 >
123 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
124 >   Firebird. Character sets with a char width of two are not UTF16.
125 >
126 > 6. Strings received from the database are now always transliterated into UTF8
127 >   regardless of the database character set or connection character set. This
128 >   is for compatibility with the LCL.
129 >
130 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
131 >
132 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
133 >   read in an entire blob just to get the size of the blob. General performance
134 >   improvement when opening datasets containing blobs.
135 >
136 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
137 >
138 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
139 >   is now used.
140 >
141 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
142 >   determined.
143 >
144 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
145 >
146 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
147 >   lazarus 1.6.0
148 >
149 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
150 >   compilation error.
151 >
152 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
153 >
154 > 1. No character set specified for connection: when a text blob is retrieved, the
155 >  character set is determined by looking up the native character set using then
156 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
157 >  set as the connection.
158 >
159 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
160 >   for Login Dialog returing a change to the database path.
161 >
162 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
163 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
164 >   entered value to be saved on a project specific basis (design time only).
165 >
166 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
167 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
168 >   Otherwise, it sets the column text to the selected ListField Value.
169 >
170 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
171 >   column width.
172 >
173 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
174 >   and a case insensitive search is requested.
175 >
176 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
177 >   or column ListSource.
178 >
179 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
180 >   unprepare) when closing and the text has not changed.
181 >
182 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
183 >   Less likely to cause a cursor re-use error on Windows.
184 >
185 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
186 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
187 >
188 > 11. TIBTreeView: Guard against nil destination on record changed
189 >
190 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
191 >    string type with the code page set to reflect the returned field encoding after
192 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
193 >    earlier versions.
194 >
195 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
196 >    will now result in transliteration to the code page specified for the Firebird driver
197 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
198 >
199 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
200 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
201 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
202 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
203 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
204 >    the GETACP is used to determine the Windows code page.
205 >
206 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
207 >    name used as the lc_ctype when the database was opened. Only valid while the
208 >    Database is connected.
209 >
210 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
211 >    id that corresponds to the DefaultCharSetName.
212 >
213 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
214 >
215 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
216 >   path is given and database attach fails due to access permission issues on the
217 >   temp directory or security database, then the attach is retried with "localhost:"
218 >   prefixing the databasename. This should avoid problems when the database has to
219 >   be accessed by a local (e.g. classic) server and libfbembed is used.
220 >
221 > 2. Windows: revised search order for Firebird DLL:
222 >     i.   The Firebird Embedded Server in the application Directory.
223 >     ii.  If the FIREBIRD environment variable is set then the directory this
224 >          points to is searched for the FB Client DLL and then then underlying
225 >          "bin" directory.
226 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
227 >          is used to locate the Firebird installation directory and the underlying
228 >          "bin" directory is searched for the FB Client DLL.
229 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
230 >          are searched for the FB Client DLL.
231 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
232 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
233 >
234 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
235 >   See doc/readme.scriptengine and example applications.
236 >
237 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
238 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
239 >   See dpc/readme.localdatabase and example applications.
240 >
241 > 5. IBDynamicGrid: Reordering on column header click should now also work for
242 >   dynamic columns.
243 >
244 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
245 >   between incrementing/decrementing the lock count and signalling the event.
246 >
247 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
248 >
249 > 1.3.2 was never formally released and only made available as beta copies.
250 >
251 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
252 >
253 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
254 >
255 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
256 >
257 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
258 >   i.e. when it is a calculated field
259 >
260 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
261 >   This problem was due to a race condition between recalculating row heights and
262 >   determining which row was selected by the mouse click. The row height calculation
263 >   is now deferred by an extra trip round the message loop allowing the row to
264 >   be always calculated on the current grid layout rather than risking it being
265 >   calculated on the grid layout after the expanded row has been shrunk.
266 >
267 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
268 >   Windows.
269 >
270 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
271 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
272 >   to be determined at runtime. See doc/readme.charactersets.html.
273 >
274 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
275 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
276 >
277 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
278 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
279 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
280 >
281 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
282 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
283 >   implies no truncation.
284 >
285 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
286 >
287 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
288 >   (avoids "Not in Edit Mode" error).
289 >
290 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
291 >
292 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
293 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
294 >
295 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
296 >
297 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
298 >
299 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
300 >
301 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
302 >
303 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
304 >
305 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
306 >
307 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
308 >     problem with row size when exception is called.
309 >
310 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
311 >
312 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
313 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
314 >
315 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
316 >     keyed in i.e. when autocomplete not performed
317 >
318 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
319 >     console mode applications with all LCL required functions (builtin dialogs and
320 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
321 >     not included in your project, IBX should compile and link with a console mode program.
322 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
323 >     console mode application or the IDE will automatically assume that your
324 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
325 >
326 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
327 >     to use the built in dialogs and cursor management. IBDialogs is
328 >     included by default if "ibexpress" is in your project source's "uses" clause.
329 >     This should be the case for all projects created through the IDE. This is why
330 >     you do not want to add the ibexpress package to console mode applications. The
331 >     ibexpressconsolemode package has been created to allow console mode programs
332 >     to avoid adding LCL dependencies when using IBX, while still having the
333 >     unit search paths set up correctly.
334 >
335 >     Existing users should check to ensure that the "ibexpress" unit is included in
336 >     each project's source file (*.lpr).
337 >
338 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
339 >     exists, you have to first open the package in the IDE and then close it. This
340 >     adds it to the most recently accessed packages list. To make it permanently
341 >     available, add the package name to lazarus' staticpackages.inc file.
342 >
343 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
344 >
345 > 7.   SQL Parser can now accept quoted strings that include new lines
346 >
347 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
348 >     of text on start of edit. This is particularly useful when tabbing to a
349 >     column and then inserting text.
350 >
351 > 9.   New Examples provided for IB Services and ISQLMonitor.
352 >
353 > 10. Fix error when writing to blob streams that recorded only the last buffer
354 >    write in the blob stream. In most cases, this did not cause a problem as the
355 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
356 >    of a graphic type prefix was lost which caused a problem when the image could
357 >        not be automatically recognised.
358 >
359 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
360 >    already open" errors due to random numbers used for the cursor name being identical.
361 >
362 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
363 >    when opening the table and the Primary Key is the last or only column in the
364 >    table. Thanks to Rick Hoover for the fix.
365 >
366 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
367 >    of "UTF-8", and update list of available database character sets. Existing
368 >    users should check the current lc_ctype setting in their applications.

483  
484   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
485      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
# Line 132 | Line 501 | IBX Change Log  version
