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. |

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 |
> |

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 |
> |

| 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 |

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. |
| 185 |
> |

IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 |

|
| 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 |
> |
|
| 246 |
> |
2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids |
| 247 |
> |
problem with row size when exception is called. |
| 248 |
> |
|
| 249 |
> |
3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. |
| 250 |
> |
|
| 251 |
> |
4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if |
| 252 |
> |
in a TCustomComboBox and ignores return key if in a TCustomMemo |
| 253 |
> |
|
| 254 |
> |
5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text |
| 255 |
> |
keyed in i.e. when autocomplete not performed |
| 256 |
> |
|
| 257 |
> |
6. Cleanup of "Uses" clauses and add console mode support. IBX should now support |
| 258 |
> |
console mode applications with all LCL required functions (builtin dialogs and |
| 259 |
> |
cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is |
| 260 |
> |
not included in your project, IBX should compile and link with a console mode program. |
| 261 |
> |
See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a |
| 262 |
> |
console mode application or the IDE will automatically assume that your |
| 263 |
> |
application is GUI based. Instead, you should include the ibexpressconsolemode package. |
| 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'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 |
> |
Thanks to Julio Jiménez for suggesting support of console mode. |
| 283 |
> |
|
| 284 |
> |
7. SQL Parser can now accept quoted strings that include new lines |
| 285 |
> |
|
| 286 |
> |
8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end |
| 287 |
> |
of text on start of edit. This is particularly useful when tabbing to a |
| 288 |
> |
column and then inserting text. |
| 289 |
> |
|
| 290 |
> |
9. New Examples provided for IB Services and ISQLMonitor. |
| 291 |
> |
|
| 292 |
> |
10. Fix error when writing to blob streams that recorded only the last buffer |
| 293 |
> |
write in the blob stream. In most cases, this did not cause a problem as the |
| 294 |
> |
IB Blob Stream is written in a single write. However, with the TDBImage, write |
| 295 |
> |
of a graphic type prefix was lost which caused a problem when the image could |
| 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 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. |
| 304 |

| 306 |

1. Firebird Services: avoid List Index error when opening a service with an |
| 312 |
> |
empty Params property. |
| 313 |

|
| 314 |
> |
2. IBControls: Fix problem with new link mechanism introduced in 1.2.3. |
| 315 |
> |
Link now set up in Loaded method - avoids occasional failure to apply |
| 316 |
> |
SQL markup on initial open. |
| 317 |

|
| 318 |

3. "Employees" example performance improvements when scrolling. |
| 319 |

|
| 320 |

4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a |
| 321 |
> |
TFrame. Force recaching of selected frame to avoid GTK race (results in a |
| 322 |
> |
random image cached). |
| 323 |
> |
|
| 324 |
> |
5. DBControlGrid: Should now react to changes in panel height at run time. |
| 325 |
> |
|
| 326 |
> |
6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid |
| 327 |
> |
even when further rows exist. |
| 328 |
> |
|
| 329 |
> |
7. DBControlGrid: DefaultRowHeight is no longer a published property as it should |
| 330 |
> |
always be derived from panel height and setting this property can cause confusion. |
| 331 |
> |
Note for existing projects: to avoid a missing property error at run time, |
| 332 |
> |
each form using the DBControlGrid must be opened, updated and saved in the IDE |
| 333 |
> |
in order to remove the property value from the lfm. |

1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike |

| 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. |
