1 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
2 >
3 > 1. No character set specified for connection: when a text blob is retrieved, the
4 >  character set is determined by looking up the native character set using then
5 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
6 >  set as the connection.
7 >
8 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
9 >   for Login Dialog returing a change to the database path.
10 >
11 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
12 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
13 >   entered value to be saved on a project specific basis (design time only).
14 >
15 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
16 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
17 >   Otherwise, it sets the column text to the selected ListField Value.
18 >
19 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
20 >   column width.
21 >
22 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
23 >   and a case insensitive search is requested.
24 >
25 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
26 >   or column ListSource.
27 >
28 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
29 >   unprepare) when closing and the text has not changed.
30 >
31 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
32 >   Less likely to cause a cursor re-use error on Windows.
33 >
34 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
35 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
36 >
37 > 11. TIBTreeView: Guard against nil destination on record changed
38 >
39 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
40 >    string type with the code page set to reflect the returned field encoding after
41 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
42 >    earlier versions.
43 >
44 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
45 >    will now result in transliteration to the code page specified for the Firebird driver
46 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
47 >
48 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
49 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
50 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
51 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
52 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
53 >    the GETACP is used to determine the Windows code page.
54 >
55 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
56 >    name used as the lc_ctype when the database was opened. Only valid while the
57 >    Database is connected.
58 >
59 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
60 >    id that corresponds to the DefaultCharSetName.
61 >
62 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
63 >
64 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
65 >   path is given and database attach fails due to access permission issues on the
66 >   temp directory or security database, then the attach is retried with "localhost:"
67 >   prefixing the databasename. This should avoid problems when the database has to
68 >   be accessed by a local (e.g. classic) server and libfbembed is used.
69 >
70 > 2. Windows: revised search order for Firebird DLL:
71 >     i.   The Firebird Embedded Server in the application Directory.
72 >     ii.  If the FIREBIRD environment variable is set then the directory this
73 >          points to is searched for the FB Client DLL and then then underlying
74 >          "bin" directory.
75 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
76 >          is used to locate the Firebird installation directory and the underlying
77 >          "bin" directory is searched for the FB Client DLL.
78 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
79 >          are searched for the FB Client DLL.
80 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
81 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
82 >
83 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
84 >   See doc/readme.scriptengine and example applications.
85 >
86 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
87 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
88 >   See dpc/readme.localdatabase and example applications.
89 >
90 > 5. IBDynamicGrid: Reordering on column header click should now also work for
91 >   dynamic columns.
92 >
93 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
94 >   between incrementing/decrementing the lock count and signalling the event.
95 >
96 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
97 >
98 > 1.3.2 was never formally released and only made available as beta copies.
99 >
100 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
101 >
102 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
103 >
104 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
105 >
106 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
107 >   i.e. when it is a calculated field
108 >
109 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
110 >   This problem was due to a race condition between recalculating row heights and
111 >   determining which row was selected by the mouse click. The row height calculation
112 >   is now deferred by an extra trip round the message loop allowing the row to
113 >   be always calculated on the current grid layout rather than risking it being
114 >   calculated on the grid layout after the expanded row has been shrunk.
115 >
116 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
117 >   Windows.
118 >
119 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
120 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
121 >   to be determined at runtime. See doc/readme.charactersets.html.
122 >
123 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
124 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
125 >
126 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
127 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
128 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
129 >
130 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
131 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
132 >   implies no truncation.
133 >
134 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
135 >
136 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
137 >   (avoids "Not in Edit Mode" error).
138 >
139 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
140 >
141 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
142 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
143 >
144 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
145 >
146 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
147 >
148 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
149 >
150 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
151 >
152 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
153 >
154 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
155 >
156 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
157 >     problem with row size when exception is called.
158 >
159 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
160 >
161 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
162 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
163 >
164 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
165 >     keyed in i.e. when autocomplete not performed
166 >
167 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
168 >     console mode applications with all LCL required functions (builtin dialogs and
169 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
170 >     not included in your project, IBX should compile and link with a console mode program.
171 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
172 >     console mode application or the IDE will automatically assume that your
173 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
174 >
175 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
176 >     to use the built in dialogs and cursor management. IBDialogs is
177 >     included by default if "ibexpress" is in your project source's "uses" clause.
178 >     This should be the case for all projects created through the IDE. This is why
179 >     you do not want to add the ibexpress package to console mode applications. The
180 >     ibexpressconsolemode package has been created to allow console mode programs
181 >     to avoid adding LCL dependencies when using IBX, while still having the
182 >     unit search paths set up correctly.
183 >
184 >     Existing users should check to ensure that the "ibexpress" unit is included in
185 >     each project's source file (*.lpr).
186 >
187 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
188 >     exists, you have to first open the package in the IDE and then close it. This
189 >     adds it to the most recently accessed packages list. To make it permanently
190 >     available, add the package name to lazarus' staticpackages.inc file.
191 >
192 >         Thanks to Julio Jiménez for suggesting support of console mode.
193 >
194 > 7.   SQL Parser can now accept quoted strings that include new lines
195 >
196 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
197 >     of text on start of edit. This is particularly useful when tabbing to a
198 >     column and then inserting text.
199 >
200 > 9.   New Examples provided for IB Services and ISQLMonitor.
201 >
202 > 10. Fix error when writing to blob streams that recorded only the last buffer
203 >    write in the blob stream. In most cases, this did not cause a problem as the
204 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
205 >    of a graphic type prefix was lost which caused a problem when the image could
206 >        not be automatically recognised.
207 >
208 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
209 >    already open" errors due to random numbers used for the cursor name being identical.
210 >
211 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
212 >    when opening the table and the Primary Key is the last or only column in the
213 >    table. Thanks to Rick Hoover for the fix.
214 >
215 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
216 >    of "UTF-8", and update list of available database character sets. Existing
217 >    users should check the current lc_ctype setting in their applications.
218 >
219 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
220 >
221 > 1.  Firebird Services: avoid List Index error when opening a service with an
222 >    empty Params property.
223 >
224 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
225 >    Link now set up in Loaded method - avoids occasional failure to apply
226 >    SQL markup on initial open.
227 >
228 > 3.  "Employees" example performance improvements when scrolling.
229 >
230 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
231 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
232 >    random image cached).
233 >
234 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
235 >
236 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
237 >    even when further rows exist.
238 >
239 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
240 >    always be derived from panel height and setting this property can cause confusion.
241 >    Note for existing projects: to avoid a missing property error at run time,
242 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
243 >    in order to remove the property value from the lfm.
244 >
245 >
246 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
247 >
248 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
249 >    call Prepare before setting parameter values.
250 >
251 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
252 >
253 > 3.  Code tidyup and more robust handling of dsql information result vector.
254 >
255 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
256 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
257 >    and "AfterExecQuery". The first three are called after the same event is called
258 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
259 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
260 >    enable monitoring of transaction status changes for a given transaction to be
261 >    handled in a single place. For example, when a change to the dataset occurs
262 >    an indicator can be set that shows the user that in order to save changes,
263 >    the transaction should be committed.  Rather than doing this per dataset, this
264 >    can now be done per transaction.
265 >
266 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
267 >    the dataset is scrolled. However, any changes to the current row are, by default,
268 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
269 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
270 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
271 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
272 >    then IBX will attempt to post any unsaved changes before the dataset is closed
273 >    (and after the BeforeClose event handler is called). The exception is when the
274 >    dataset is being closed as a result of a transaction rollback. In this case,
275 >    no action is taken and any unsaved  changes are discarded. This avoids both
276 >    unnecessary overhead and the risk that a validation error may occur in the Post
277 >    raising an exception and thereby preventing a rollback.
278 >
279 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
280 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
281 >    width. Display Widths are now corrected by dividing by the max byte width per character.
282 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
283 >    the byte width divided by 4. The byte width of each character set is determined
284 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
285 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
286 >
287 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
288 >
289 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
290 >    control loses focus. Default Key press default interval reduced to 200ms.
291 >
292 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
293 >    when dataset rows are less than visible rows.
294 >
295 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
296 >    does not exist or DataSet is empty. More responsive on dataset open. New event
297 >    OnRestorePosition. Column sort disabled if no header row.
298 >
299 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
300 >    while dataset state is dsInsert. Avoids posting errors.
301 >
302 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
303 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
304 >
305 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
306 >
307 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
308 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
309 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
310 >    always "posts" the current record regardless or whether or not it may be more appropriate
311 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
312 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
313 >    as the first action of the "Post" method and allows the handler to convert the Post
314 >    into a Cancel if that is the appropriate action on moving to a different row. This is
315 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
316 >    raised here, but it may still be more appropriate to validate a post and signal
317 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
318 >
319 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
320 >    separated list. Each library name on the list is tried in turn, in left to right
321 >    order with the first found being used as the firebird library. By default, on Linux,
322 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
323 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
324 >
325 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
326 >    then it will still attempt to access the database via the Firebird Server and will
327 >    require a username and password. If only the pathname is given, then the username
328 >    and password should be omitted and the unix file permissions are used to grant
329 >    access.
330 >
331 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
332 >
333 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
334 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
335 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
336 >    corresponds to a row of the linked DataSource. Any data aware control on the
337 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
338 >
339 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
340 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
341 >   takes place during database access. This may be useful when there are performance issues with
342 >   the change of cursor. Setting the property to false suppresses the change of cursor.
343 >
344 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
345 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
346 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
347 >   making all changes permanent immediately rather than when the transaction is explicitly
348 >   committed.
349 >
350 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
351 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
352 >
353 > IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000

355 > Development version only.
356 >
357 > IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
358 >
359 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
360 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
361 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
362 >   complexity.
363 >
364 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
365 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
366 >   These are:
367 >
368 >   - TIBLookupComboEditBox
369 >   - TIBDynamicGrid
370 >   - TIBTreeview
371 >
372 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
373 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
374 >   to revise the available list and restrict it to items that are prefixed by the
375 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
376 >   newly typed entry to be added to the list dataset and included in the available
377 >   list items.
378 >
379 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
380 >   - automatic resizing of selected columns to fill the available row length
381 >   - automatic positioning and sizing of a "totals" control, typically at the
382 >     column footer, on a per column basis.
383 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
384 >     A second click on the same header cell reversed the sort order.
385 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
386 >     is automatically expanded and a panel superimposed on it. The panel can have any
387 >     number of child controls, typically data aware controls with the same datasource
