1 + IBX Change Log  version                               (2.1-1) Fri, 05 Jan 2018 10:40:04 +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 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
16 +
17 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
18 +   changes.
19 +
20 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
21 +   Bug could result in truncated multi-byte character set values.
22 +
23 + 3. Changes consequential on moving fbintf character set utility functions from
24 +   IFirebirdAPI to IAttachment.
25 +
26 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
27 +
28 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
29 +   results in autocomplete ignoring prefix text.
30 +
31 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
32 +   entering a new name into the text box.
33 +
34 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
35 +   Firebird rather than recomputing it.
36 +
37 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
38 +   screen centre. Previously some were "poDesigned" which may be inappropriate
39 +   for multi monitor desktops.
40 +
41 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
42 +
43 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
44 +    a transaction and always reset the object.
45 +
46 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
47 +
48 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
49 +
50 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
51 +    to a gbak format archive.
52 +
53 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
54 +
55 + 16. IBLocaldb: Drop database if error creating an empty database.
56 +
57 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
58 +    unless selected node not in current dataset.
59 +
60 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
61 +    to TIBCustomService, and IBlocalDB code tidy up.
62 +
63 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
64 +    behaviour due to uninitialised variable.
65 +
66 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
67 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
68 +
69 + 21. IBSQL: When Database changed ensure that all resources are freed.
70 +
71 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
72 +
73 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
74 +    * Line Wrap on SQL Token boundaries (on user command)
75 +    * auto-complete table names in drop down list of table names
76 +    * Double click on tablename or field name adds to SQL text
77 +
78 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
79 +
80 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
81 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
82 +    workaround for a problem in fpc 3.0.4 win64).
83 +
84 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
85 +
86 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
87 +
88 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
89 +
90 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
91 +   include remote system name.
92 +
93 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
94 +   tables when data included in output.
95 +
96 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
97 +   and timing information to be written to stdout. This may be used to locate
98 +   performance bottlenecks.
99 +
100 + 4. SQLParser: only call "OnChanging" event handler when value is different.
101 +
102 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
103 +
104 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
105 +   that BindFields is called when the query is next activated. Avoids FieldName
106 +   not found error.
107 +
108 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
109 +   purpose and allows the programmer to define any action they want for Update, Insert
110 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
111 +   filtering of updates, or use of statements such as Grant or Revoke instead of
112 +   normal DML. See User Manual for more information.
113 +
114 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
115 +
116 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
117 +
118 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
119 +
120 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
121 +   hexadecimal notation.
122 +
123 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
124 +   using a simple XML format.
125 +
126 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
127 +   grants to these objects.
128 +
129 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
130 +   dependency problems restoring complex databases.
131 +
132 + 7. TIBXScript: This component has been restructured to allow for the processing of
133 +   embedded XML in INSERT statements and to support interactive sources in addition
134 +   to non-interactive data sources such as files.
135 +
136 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
137 +
138 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
139 +   SET SQL DIALECT
140 +   SET TERM
141 +   SET AUTODDL
142 +   SET BAIL
143 +   SET ECHO
144 +   SET COUNT
145 +   SET STATS
146 +   SET NAMES <character set>
147 +
148 + 10. IBVersion unit added to hold current IBX Version Number information.
149 +
150 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
151 +    and domain definitions.
152 +
153 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
154 +    fully supported.
155 +
156 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
157 +
158 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
159 +
160 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
161 +
162 + See also doc/IBX4LazarusGuide.pdf for important information on
163 + upgrading to IBX2.
164 +
165 + 1. Size property of TIBStringField is now the width in characters of the field
166 +   and not the byte length. This applies only to multi-byte character sets such
167 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
168 +   code is not recognised as a bug and hence this change to align the behaviour.
169 +   The TStringField change is expected in fpc 3.2.0.
170 +
171 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
172 +   true (default) then Size property value saved in the lfm is ignored. Size is
173 +   always set from the dynamic information read from the database. It is unclear
174 +   why anyone would want to override this and set Size to false.
175 +
176 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
177 +   block.
178 +
179 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
180 +   exist when an attempt is made to connect to it (run time only) then an attempt
181 +   is made to create the database.
182 +
183 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
184 +   has been successfully created as a result of a call to CreateDatabase or when
185 +   creating a database after it was found not to exist.
186 +
187 + 6.  DBControlGrid: a race condition could result in the wrong row image being
188 +    written to the cache. This has been avoided by a trip round the message
189 +    loop before rendering the row image.
190 +
191 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
192 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
193 +    known to risk corrupt rendering of row images when the control is first
194 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
195 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
196 +
197 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
198 +    a TDateEdit control located on an editor panel.
199 +
200 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
201 +
202 + 10. DBControlGrid: Removed memory leak when updating rows.
203 +
204 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
205 +
206 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
207 +
208 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
209 +   when target codepage is CP_NONE. This is a workaround for
210 +   http://bugs.freepascal.org/view.php?id=30622.
211 +
212 + 2. DBLog option removed from TIBStatisticalService - not supported by server
213 +   since Firebird 1.5.
214 +
215 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
216 +   similar.
217 +
218 + 4. IBCodePage: updated mapping between codepages and character id.
219 +
220 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
221 +   Firebird. Character sets with a char width of two are not UTF16.
222 +
223 + 6. Strings received from the database are now always transliterated into UTF8
224 +   regardless of the database character set or connection character set. This
225 +   is for compatibility with the LCL.
226 +
227 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
228 +
229 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
230 +   read in an entire blob just to get the size of the blob. General performance
231 +   improvement when opening datasets containing blobs.
232 +
233 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
234 +
235 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
236 +   is now used.
237 +
238 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
239 +   determined.
240 +
241 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
242 +
243 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
244 +   lazarus 1.6.0
245 +
246 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
247 +   compilation error.
248 +
