1 + IBX Change Log  version                  (2.0-2) tba, 09 Jan 2017 15:31:49 +0000
2 +
3 + 1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
4 +   include remote system name.
5 +
6 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
7 +   tables when data included in output.
8 +
9 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
10 +   and timing information to be written to stdout. This may be used to locate
11 +   performance bottlenecks.
12 +
13 + 4. SQLParser: only call "OnChanging" event handler when value is different.
14 +
15 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
16 +
17 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
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
27 +   using a simple XML format.
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:
42 +   SET SQL DIALECT
43 +   SET TERM
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.
52 +
53 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
54 +    and domain definitions.
55 +
56 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
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 +
