1 + IBX Change Log  version                                    (2.2-0) Mon, 15 Jan 2018 23:43:19 +0000
2 +
3 + 1. IBExtract: Identity columns - add additional 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). However, this is also a very useful mechanism for returning updated computed by
8 +   column values. Values returned as a result of executing an Insert or Update statement
9 +   replace existing values in the current row for each corresponding column.
10 +
11 +   Previously, if a dataset's select query included read only (computed by) fields then
12 +   an automatic row refresh was performed after an insert or update query had been processed,
13 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 +   that an automatic refresh is no longer performed if an insert or update query contains
15 +   a returning clause that updates one or more fields on the current row. A full row
16 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17 +   field values and the select query contains read only fields. Use of Insert/update
18 +   returning should be significantly more efficient than excuting a refresh query.
19 +
20 +   This behaviour change is intended to be backwards compatible and there should be no need to change
21 +   existing programs, other than to improve performance by using the new capability.
22 +
23 + 3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
24 +   any Computed By or Identity Columns. The IBTables example has been updated to
25 +   illustrate the computation of the employee Full Name on update.
26 +
27 + 4. TIBTable: The GeneratorField property is now published.
28 +
29 + 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
30 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
31 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
32 +   each Identity column after the insert is executed.
33 +
34 + 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
35 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
36 +   Insert..Returning clause.
37 +
38 + 7. TIBGenerator: small performance improvement by not preparing query each time
39 +   a new value is generated.
40 +
41 + 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
42 +
43 + 9. Property editors will now sync table name to a System Table when "Include System
44 +   Tables" is selected and the query is for a System Table.
45 +
46 + 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
47 +    values are no longer converted to milliseconds from TDateTime and then back again
48 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
49 +
50 + 11. Property Editors handling of Stored Procedures.
51 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
52 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
53 +      query).
54 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
55 +
56 + 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
57 +    can be used to select a package. If non-empty, the stored procedure name is
58 +    expected to be a stored procedure defined in the specified package and the
59 +    generated SQL will be as required for a stored procedure located in a package.
60 +
61 + 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
62 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
63 +    which a stored procedure can be selected. With no package name selected, non-package
64 +    stored procedures are listed.
65 +
66 +
67 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
68 +
69 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
70 +   changes.
71 +
72 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
73 +   Bug could result in truncated multi-byte character set values.
74 +
75 + 3. Changes consequential on moving fbintf character set utility functions from
76 +   IFirebirdAPI to IAttachment.
77 +
78 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
79 +
80 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
81 +   results in autocomplete ignoring prefix text.
82 +
83 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
84 +   entering a new name into the text box.
85 +
86 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
87 +   Firebird rather than recomputing it.
88 +
89 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
90 +   screen centre. Previously some were "poDesigned" which may be inappropriate
91 +   for multi monitor desktops.
92 +
93 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
94 +
95 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
96 +    a transaction and always reset the object.
97 +
98 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
99 +
100 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
101 +
102 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
103 +    to a gbak format archive.
104 +
105 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
106 +
107 + 16. IBLocaldb: Drop database if error creating an empty database.
108 +
109 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
110 +    unless selected node not in current dataset.
111 +
112 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
113 +    to TIBCustomService, and IBlocalDB code tidy up.
114 +
115 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
116 +    behaviour due to uninitialised variable.
117 +
118 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
119 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
120 +
121 + 21. IBSQL: When Database changed ensure that all resources are freed.
122 +
123 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
124 +
125 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
126 +    * Line Wrap on SQL Token boundaries (on user command)
127 +    * auto-complete table names in drop down list of table names
128 +    * Double click on tablename or field name adds to SQL text
129 +
130 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
131 +
132 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
133 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
134 +    workaround for a problem in fpc 3.0.4 win64).
135 +
136 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
137 +
138 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
139 +
140 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
141 +
142 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
143 +   include remote system name.
144 +
145 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
146 +   tables when data included in output.
147 +
148 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
149 +   and timing information to be written to stdout. This may be used to locate
150 +   performance bottlenecks.
151 +
152 + 4. SQLParser: only call "OnChanging" event handler when value is different.
153 +
154 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
155 +
156 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
157 +   that BindFields is called when the query is next activated. Avoids FieldName
158 +   not found error.
159 +
160 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
161 +   purpose and allows the programmer to define any action they want for Update, Insert
162 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
163 +   filtering of updates, or use of statements such as Grant or Revoke instead of
164 +   normal DML. See User Manual for more information.
165 +
166 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
167 +
168 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
169 +
170 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
171 +
172 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
173 +   hexadecimal notation.
174 +
175 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
176 +   using a simple XML format.
177 +
178 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
179 +   grants to these objects.
180 +
181 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
182 +   dependency problems restoring complex databases.
183 +
184 + 7. TIBXScript: This component has been restructured to allow for the processing of
185 +   embedded XML in INSERT statements and to support interactive sources in addition
186 +   to non-interactive data sources such as files.
187 +
188 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
189 +
190 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
191 +   SET SQL DIALECT
192 +   SET TERM
193 +   SET AUTODDL
194 +   SET BAIL
195 +   SET ECHO
196 +   SET COUNT
197 +   SET STATS
198 +   SET NAMES <character set>
199 +
200 + 10. IBVersion unit added to hold current IBX Version Number information.
201 +
202 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
203 +    and domain definitions.
204 +
205 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
206 +    fully supported.
207 +
208 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
209 +
210 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
211 +
212 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
213 +
214 + See also doc/IBX4LazarusGuide.pdf for important information on
215 + upgrading to IBX2.
216 +
217 + 1. Size property of TIBStringField is now the width in characters of the field
218 +   and not the byte length. This applies only to multi-byte character sets such
219 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
220 +   code is not recognised as a bug and hence this change to align the behaviour.
221 +   The TStringField change is expected in fpc 3.2.0.
222 +
223 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
224 +   true (default) then Size property value saved in the lfm is ignored. Size is
225 +   always set from the dynamic information read from the database. It is unclear
226 +   why anyone would want to override this and set Size to false.
227 +
228 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
229 +   block.
230 +
231 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
232 +   exist when an attempt is made to connect to it (run time only) then an attempt
233 +   is made to create the database.
234 +
235 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
236 +   has been successfully created as a result of a call to CreateDatabase or when
237 +   creating a database after it was found not to exist.
238 +
239 + 6.  DBControlGrid: a race condition could result in the wrong row image being
240 +    written to the cache. This has been avoided by a trip round the message
241 +    loop before rendering the row image.
242 +
243 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
244 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
245 +    known to risk corrupt rendering of row images when the control is first
246 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
247 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
248 +
249 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
250 +    a TDateEdit control located on an editor panel.
251 +
252 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
253 +
254 + 10. DBControlGrid: Removed memory leak when updating rows.
255 +
256 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
257 +
258 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
259 +
260 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
261 +   when target codepage is CP_NONE. This is a workaround for
262 +   http://bugs.freepascal.org/view.php?id=30622.
263 +
264 + 2. DBLog option removed from TIBStatisticalService - not supported by server
265 +   since Firebird 1.5.
266 +
267 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
268 +   similar.
269 +
270 + 4. IBCodePage: updated mapping between codepages and character id.
271 +
272 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
273 +   Firebird. Character sets with a char width of two are not UTF16.
274 +
275 + 6. Strings received from the database are now always transliterated into UTF8
276 +   regardless of the database character set or connection character set. This
277 +   is for compatibility with the LCL.
278 +
279 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
280 +
281 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
282 +   read in an entire blob just to get the size of the blob. General performance
283 +   improvement when opening datasets containing blobs.
284 +
285 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
286 +
287 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
288 +   is now used.
289 +
290 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
291 +   determined.
292 +
293 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
294 +
295 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
296 +   lazarus 1.6.0
297 +
298 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
299 +   compilation error.
300 +
301 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
302 +
303 + 1. No character set specified for connection: when a text blob is retrieved, the
304 +  character set is determined by looking up the native character set using then
305 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
306 +  set as the connection.
307 +
308 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
309 +   for Login Dialog returing a change to the database path.
310 +
311 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
312 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
313 +   entered value to be saved on a project specific basis (design time only).
314 +
315 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
316 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
317 +   Otherwise, it sets the column text to the selected ListField Value.
318 +
319 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
320 +   column width.
321 +
322 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
323 +   and a case insensitive search is requested.
324 +
325 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
326 +   or column ListSource.
327 +
328 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
329 +   unprepare) when closing and the text has not changed.
330 +
331 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
332 +   Less likely to cause a cursor re-use error on Windows.
333 +
334 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
335 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
336 +
337 + 11. TIBTreeView: Guard against nil destination on record changed
338 +
339 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
340 +    string type with the code page set to reflect the returned field encoding after
341 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
342 +    earlier versions.
343 +
344 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
345 +    will now result in transliteration to the code page specified for the Firebird driver
346 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
347 +
348 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
349 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
350 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
351 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
352 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
353 +    the GETACP is used to determine the Windows code page.
354 +
355 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
356 +    name used as the lc_ctype when the database was opened. Only valid while the
357 +    Database is connected.
358 +
359 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
360 +    id that corresponds to the DefaultCharSetName.
361 +
