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 >

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.

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.

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
# Line 16 | Line 372 | IBX Change Log  version
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 insenstive). Autoinsert allows a
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.
