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