1 + IBX Change Log  version                                  (2.1-1) Sun, 07 Jan 2018 15:15:13 +0000
2 +
3 + 1. IBExtract: Identity columns - add addition check for null column for generator name.
4 +
5 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 +   information). Values returned as a result of executing an Insert or Update statement
8 +   replace existing values in the current row for each corresponding column.
9 +
10 + 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 +   each Identity column after the insert is executed.
14 +
15 + 4. TIBGenerator: small performance improvement by not preparing query each time
16 +   a new number is generated.
17 +
18 + 5. TIBSQL: Free resources when transaction changed.
19 +
20 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
21 +
22 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
23 +   changes.
24 +
25 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
26 +   Bug could result in truncated multi-byte character set values.
27 +
28 + 3. Changes consequential on moving fbintf character set utility functions from
29 +   IFirebirdAPI to IAttachment.
30 +
31 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
32 +
33 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
34 +   results in autocomplete ignoring prefix text.
35 +
36 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
37 +   entering a new name into the text box.
38 +
39 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
40 +   Firebird rather than recomputing it.
41 +
42 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
43 +   screen centre. Previously some were "poDesigned" which may be inappropriate
44 +   for multi monitor desktops.
45 +
46 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
47 +
48 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
49 +    a transaction and always reset the object.
50 +
51 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
52 +
53 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
54 +
55 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
56 +    to a gbak format archive.
57 +
58 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
59 +
60 + 16. IBLocaldb: Drop database if error creating an empty database.
61 +
62 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
63 +    unless selected node not in current dataset.
64 +
65 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
66 +    to TIBCustomService, and IBlocalDB code tidy up.
67 +
68 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
69 +    behaviour due to uninitialised variable.
70 +
71 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
72 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
73 +
74 + 21. IBSQL: When Database changed ensure that all resources are freed.
75 +
76 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
77 +
78 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
79 +    * Line Wrap on SQL Token boundaries (on user command)
80 +    * auto-complete table names in drop down list of table names
81 +    * Double click on tablename or field name adds to SQL text
82 +
83 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
84 +
85 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
86 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
87 +    workaround for a problem in fpc 3.0.4 win64).
88 +
89 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
90 +
91 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
92 +
93 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
94 +
95 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
96 +   include remote system name.
97 +
98 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
99 +   tables when data included in output.
100 +
101 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
102 +   and timing information to be written to stdout. This may be used to locate
103 +   performance bottlenecks.
104 +
105 + 4. SQLParser: only call "OnChanging" event handler when value is different.
106 +
107 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
108 +
109 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
110 +   that BindFields is called when the query is next activated. Avoids FieldName
111 +   not found error.
112 +
113 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
114 +   purpose and allows the programmer to define any action they want for Update, Insert
115 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
116 +   filtering of updates, or use of statements such as Grant or Revoke instead of
117 +   normal DML. See User Manual for more information.
118 +
119 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
120 +
121 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
122 +
123 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
124 +
125 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
126 +   hexadecimal notation.
127 +
128 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
129 +   using a simple XML format.
130 +
131 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
132 +   grants to these objects.
133 +
134 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
135 +   dependency problems restoring complex databases.
136 +
137 + 7. TIBXScript: This component has been restructured to allow for the processing of
138 +   embedded XML in INSERT statements and to support interactive sources in addition
139 +   to non-interactive data sources such as files.
140 +
141 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
142 +
143 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
144 +   SET SQL DIALECT
145 +   SET TERM
146 +   SET AUTODDL
147 +   SET BAIL
148 +   SET ECHO
149 +   SET COUNT
150 +   SET STATS
151 +   SET NAMES <character set>
152 +
153 + 10. IBVersion unit added to hold current IBX Version Number information.
154 +
155 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
156 +    and domain definitions.
157 +
158 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
159 +    fully supported.
160 +
161 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
162 +
163 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
164 +
165 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
166 +
167 + See also doc/IBX4LazarusGuide.pdf for important information on
168 + upgrading to IBX2.
169 +
170 + 1. Size property of TIBStringField is now the width in characters of the field
171 +   and not the byte length. This applies only to multi-byte character sets such
172 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
173 +   code is not recognised as a bug and hence this change to align the behaviour.
174 +   The TStringField change is expected in fpc 3.2.0.
175 +
176 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
177 +   true (default) then Size property value saved in the lfm is ignored. Size is
178 +   always set from the dynamic information read from the database. It is unclear
179 +   why anyone would want to override this and set Size to false.
180 +
181 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
182 +   block.
183 +
184 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
185 +   exist when an attempt is made to connect to it (run time only) then an attempt
186 +   is made to create the database.
187 +
188 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
189 +   has been successfully created as a result of a call to CreateDatabase or when
190 +   creating a database after it was found not to exist.
191 +
192 + 6.  DBControlGrid: a race condition could result in the wrong row image being
193 +    written to the cache. This has been avoided by a trip round the message
194 +    loop before rendering the row image.
195 +
196 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
197 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
198 +    known to risk corrupt rendering of row images when the control is first
199 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
200 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
201 +
202 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
203 +    a TDateEdit control located on an editor panel.
204 +
205 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
206 +
207 + 10. DBControlGrid: Removed memory leak when updating rows.
208 +
209 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
210 +
211 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
212 +
213 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
214 +   when target codepage is CP_NONE. This is a workaround for
215 +   http://bugs.freepascal.org/view.php?id=30622.
216 +
217 + 2. DBLog option removed from TIBStatisticalService - not supported by server
218 +   since Firebird 1.5.
219 +
220 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
221 +   similar.
222 +
223 + 4. IBCodePage: updated mapping between codepages and character id.
224 +
225 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
226 +   Firebird. Character sets with a char width of two are not UTF16.
227 +
228 + 6. Strings received from the database are now always transliterated into UTF8
229 +   regardless of the database character set or connection character set. This
230 +   is for compatibility with the LCL.
231 +
232 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
233 +
234 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
235 +   read in an entire blob just to get the size of the blob. General performance
236 +   improvement when opening datasets containing blobs.
237 +
238 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
239 +
240 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
241 +   is now used.
242 +
243 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
244 +   determined.
245 +
246 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
247 +
248 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
249 +   lazarus 1.6.0
250 +
251 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
252 +   compilation error.
253 +
254 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
255 +
256 + 1. No character set specified for connection: when a text blob is retrieved, the
257 +  character set is determined by looking up the native character set using then
258 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
259 +  set as the connection.
260 +
261 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
262 +   for Login Dialog returing a change to the database path.
263 +
264 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
265 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
266 +   entered value to be saved on a project specific basis (design time only).
267 +
268 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
269 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
270 +   Otherwise, it sets the column text to the selected ListField Value.
271 +
272 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
273 +   column width.
274 +
275 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
276 +   and a case insensitive search is requested.
277 +
278 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
279 +   or column ListSource.
280 +
281 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
282 +   unprepare) when closing and the text has not changed.
283 +
284 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
285 +   Less likely to cause a cursor re-use error on Windows.
286 +
287 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
288 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
289 +
290 + 11. TIBTreeView: Guard against nil destination on record changed
291 +
292 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
293 +    string type with the code page set to reflect the returned field encoding after
294 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
295 +    earlier versions.
296 +
297 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
298 +    will now result in transliteration to the code page specified for the Firebird driver
299 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
300 +
301 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
302 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
303 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
304 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
305 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
306 +    the GETACP is used to determine the Windows code page.
307 +
308 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
309 +    name used as the lc_ctype when the database was opened. Only valid while the
310 +    Database is connected.
311 +
312 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
313 +    id that corresponds to the DefaultCharSetName.
314 +
315 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
316 +
317 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
318 +   path is given and database attach fails due to access permission issues on the
319 +   temp directory or security database, then the attach is retried with "localhost:"
320 +   prefixing the databasename. This should avoid problems when the database has to
321 +   be accessed by a local (e.g. classic) server and libfbembed is used.
322 +
323 + 2. Windows: revised search order for Firebird DLL:
324 +     i.   The Firebird Embedded Server in the application Directory.
325 +     ii.  If the FIREBIRD environment variable is set then the directory this
326 +          points to is searched for the FB Client DLL and then then underlying
327 +          "bin" directory.
328 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
329 +          is used to locate the Firebird installation directory and the underlying
330 +          "bin" directory is searched for the FB Client DLL.
331 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
332 +          are searched for the FB Client DLL.
333 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
334 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
335 +
336 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
337 +   See doc/readme.scriptengine and example applications.
338 +
339 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
340 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
341 +   See dpc/readme.localdatabase and example applications.
342 +
343 + 5. IBDynamicGrid: Reordering on column header click should now also work for
344 +   dynamic columns.
345 +
346 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
347 +   between incrementing/decrementing the lock count and signalling the event.
348 +
349   IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
350  
351 + 1.3.2 was never formally released and only made available as beta copies.
352 +
353   1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
354  
355   2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
# Line 21 | Line 371 | IBX Change Log  version           (1.3-2
371  
372   7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
373     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
374 <   to be determined at runtime.
374 >   to be determined at runtime. See doc/readme.charactersets.html.
375  
376   8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
377 <   TWideStringField. This field type is used with the character size reported by Firebird is two.
377 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
378  
379   9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
380     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
381 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
381 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
382  
383     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
384     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
