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 >

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 >

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 >

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 >

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
