6 >
7 > 1. Size property of TIBStringField is now the width in characters of the field
8 >   and not the byte length. This applies only to multi-byte character sets such
9 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
10 >   code is not recognised as a bug and hence this change to align the behaviour.
11 >   The TStringField change is expected in fpc 3.2.0.
12 >
13 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
14 >   true (default) then Size property value saved in the lfm is ignored. Size is
15 >   always set from the dynamic information read from the database. It is unclear
16 >   why anyone would want to override this and set Size to false.
17 >
18 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
19 >   block.
20 >
21 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
22 >   exist when an attempt is made to connect to it (run time only) then an attempt
23 >   is made to create the database.
24 >
25 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
26 >   has been successfully created as a result of a call to CreateDatabase or when
27 >   creating a database after it was found not to exist.
28 >
29 > 6.  DBControlGrid: a race condition could result in the wrong row image being
30 >    written to the cache. This has been avoided by a trip round the message
31 >    loop before rendering the row image.
32 >
33 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
34 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
35 >    known to risk corrupt rendering of row images when the control is first
36 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
37 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
38 >
39 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
40 >    a TDateEdit control located on an editor panel.
41 >
42 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
43 >
44 > 10. DBControlGrid: Removed memory leak when updating rows.
45 >
46 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

49 >
50 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
51 >   when target codepage is CP_NONE. This is a workaround for
52 >   http://bugs.freepascal.org/view.php?id=30622.
53 >
54 > 2. DBLog option removed from TIBStatisticalService - not supported by server
55 >   since Firebird 1.5.
56 >
57 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
58 >   similar.
59 >
60 > 4. IBCodePage: updated mapping between codepages and character id.
61 >
62 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
63 >   Firebird. Character sets with a char width of two are not UTF16.
64 >
65 > 6. Strings received from the database are now always transliterated into UTF8
66 >   regardless of the database character set or connection character set. This
67 >   is for compatibility with the LCL.

69 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
70 >
71 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
72 >   read in an entire blob just to get the size of the blob. General performance
73 >   improvement when opening datasets containing blobs.
74 >
75 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
76 >
77 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
78 >   is now used.
79 >
80 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
81 >   determined.
82 >
83 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
84 >
85 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
86 >   lazarus 1.6.0
87 >
88 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
89 >   compilation error.
90 >
91 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
92 >
93 > 1. No character set specified for connection: when a text blob is retrieved, the
94 >  character set is determined by looking up the native character set using then
95 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
96 >  set as the connection.
97 >
98 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
99 >   for Login Dialog returing a change to the database path.
100 >
101 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
102 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
103 >   entered value to be saved on a project specific basis (design time only).
104 >
105 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
106 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
107 >   Otherwise, it sets the column text to the selected ListField Value.
108 >
109 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
110 >   column width.
111 >
112 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
113 >   and a case insensitive search is requested.
114 >
115 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
116 >   or column ListSource.
117 >
118 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
119 >   unprepare) when closing and the text has not changed.
120 >
121 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
122 >   Less likely to cause a cursor re-use error on Windows.
123 >
124 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
125 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
126 >
127 > 11. TIBTreeView: Guard against nil destination on record changed
128 >
129 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
130 >    string type with the code page set to reflect the returned field encoding after
131 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
132 >    earlier versions.
133 >
134 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
135 >    will now result in transliteration to the code page specified for the Firebird driver
136 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
137 >
138 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
139 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
140 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
141 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
142 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
143 >    the GETACP is used to determine the Windows code page.
144 >
145 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
146 >    name used as the lc_ctype when the database was opened. Only valid while the
147 >    Database is connected.
148 >
149 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
150 >    id that corresponds to the DefaultCharSetName.

153 >
154 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
155 >   path is given and database attach fails due to access permission issues on the
156 >   temp directory or security database, then the attach is retried with "localhost:"
157 >   prefixing the databasename. This should avoid problems when the database has to
158 >   be accessed by a local (e.g. classic) server and libfbembed is used.
159 >
160 > 2. Windows: revised search order for Firebird DLL:
161 >     i.   The Firebird Embedded Server in the application Directory.
162 >     ii.  If the FIREBIRD environment variable is set then the directory this
163 >          points to is searched for the FB Client DLL and then then underlying
164 >          "bin" directory.
165 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
166 >          is used to locate the Firebird installation directory and the underlying
167 >          "bin" directory is searched for the FB Client DLL.
168 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
169 >          are searched for the FB Client DLL.
170 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
171 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
172 >
173 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
174 >   See doc/readme.scriptengine and example applications.
175 >
176 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
177 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
178 >   See dpc/readme.localdatabase and example applications.
179 >
180 > 5. IBDynamicGrid: Reordering on column header click should now also work for
181 >   dynamic columns.
182 >
183 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
184 >   between incrementing/decrementing the lock count and signalling the event.

187 >
188 > 1.3.2 was never formally released and only made available as beta copies.
189 >
190 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
191 >
192 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
193 >
194 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
195 >
196 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
197 >   i.e. when it is a calculated field
198 >
199 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
200 >   This problem was due to a race condition between recalculating row heights and
201 >   determining which row was selected by the mouse click. The row height calculation
202 >   is now deferred by an extra trip round the message loop allowing the row to
203 >   be always calculated on the current grid layout rather than risking it being
204 >   calculated on the grid layout after the expanded row has been shrunk.
205 >
206 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
207 >   Windows.
208 >
209 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
210 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
211 >   to be determined at runtime. See doc/readme.charactersets.html.
212 >
213 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
214 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
215 >
216 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
217 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
218 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
219 >
220 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
221 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
222 >   implies no truncation.
223 >
224 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
225 >
226 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
227 >   (avoids "Not in Edit Mode" error).
228 >
229 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
230 >
231 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
232 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
233 >
234 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
235 >
236 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
237 >
238 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
239 >
240 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

244   1.   OnCloseUp Event Handler added to TDBLookupProperties
245  
# Line 13 | Line 254 | IBX Change Log  version      (1.3-0) Tue

264  
265       IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
266       to use the built in dialogs and cursor management. IBDialogs is
267 <     included by default if "ibexpress" is in your project source "uses" clause.
267 >     included by default if "ibexpress" is in your project source's "uses" clause.
268       This should be the case for all projects created through the IDE. This is why
269       you do not want to add the ibexpress package to console mode applications. The
270       ibexpressconsolemode package has been created to allow console mode programs
271       to avoid adding LCL dependencies when using IBX, while still having the
272       unit search paths set up correctly.
273  
274 +     Existing users should check to ensure that the "ibexpress" unit is included in
275 +     each project's source file (*.lpr).
276 +
277       You may find that in order for the IDE to recognise that ibexpressconsolemode
278       exists, you have to first open the package in the IDE and then close it. This
279       adds it to the most recently accessed packages list. To make it permanently
280       available, add the package name to lazarus' staticpackages.inc file.
281  
282 <     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.
282 >         Thanks to Julio Jiménez for suggesting support of console mode.
283  
284   7.   SQL Parser can now accept quoted strings that include new lines

296          not be automatically recognised.
297  
298   11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
299 <    already open" errors due to random numbers being identical.
299 >    already open" errors due to random numbers used for the cursor name being identical.
300  
301   12. IBTable: corrected error that could result in an "Index out of bounds" error
302      when opening the table and the Primary Key is the last or only column in the
303      table. Thanks to Rick Hoover for the fix.

305 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
306 >    of "UTF-8", and update list of available database character sets. Existing

422  
423   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
424      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
# Line 197 | Line 440 | IBX Change Log  version
440   4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
441     using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
