IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000 |
| 3 |
+ |
|
| 4 |
+ |
See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on |
| 5 |
+ |
upgrading to IBX2. |
| 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. |
| 47 |
+ |

+ |
|
| 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. |
| 68 |
+ |
|

+ |
|
| 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 |
+ |
|

+ |
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. |
| 151 |
+ |
