2 >
3 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 >   changes.
5 >
6 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 >   Bug could result in truncated multi-byte character set values.
8 >
9 > 3. Changes consequential on moving fbintf character set utility functions from
10 >   IFirebirdAPI to IAttachment.
11 >
12 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
13 >
14 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 >   results in autocomplete ignoring prefix text.
16 >
17 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 >   entering a new name into the text box.
19 >
20 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21 >   Firebird rather than recomputing it.
22 >
23 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
24 >   screen centre. Previously some were "poDesigned" which may be inappropriate
25 >   for multi monitor desktops.
26 >
27 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
28 >
29 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
30 >    a transaction and always reset the object.
31 >
32 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
33 >
34 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
35 >
36 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
37 >    to a gbak format archive.
38 >
39 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
40 >
41 > 16. IBLocaldb: Drop database if error creating an empty database.
42 >
43 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
44 >    unless selected node not in current dataset.
45 >
46 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
47 >    to TIBCustomService, and IBlocalDB code tidy up.
48 >
49 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
50 >    behaviour due to uninitialised variable.
51 >
52 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
53 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
54 >
55 > 21. IBSQL: When Database changed ensure that all resources are freed.
56 >
57 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
58 >
59 > 23. SQL Property Editors now use SynEdit with SQL Highlighter.
60 >
61 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
62 >
63 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
64 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
65 >    workaround for a problem in fpc 3.0.4 win64).
66 >
67 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
68 >
69 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
70 >
71 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
72 >
73 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
74 >   include remote system name.
75 >
76 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
77 >   tables when data included in output.
78 >
79 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
80 >   and timing information to be written to stdout. This may be used to locate
81 >   performance bottlenecks.
82 >
83 > 4. SQLParser: only call "OnChanging" event handler when value is different.
84 >
85 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
86 >
87 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
88 >   that BindFields is called when the query is next activated. Avoids FieldName
89 >   not found error.
90 >
91 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
92 >   purpose and allows the programmer to define any action they want for Update, Insert
93 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
94 >   filtering of updates, or use of statements such as Grant or Revoke instead of
95 >   normal DML. See User Manual for more information.
96 >
97 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
98 >
99 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
100 >
101 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
102 >
103 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
104 >   hexadecimal notation.
105 >
106 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
107 >   using a simple XML format.
108 >
109 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
110 >   grants to these objects.
111 >
112 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
113 >   dependency problems restoring complex databases.
114 >
115 > 7. TIBXScript: This component has been restructured to allow for the processing of
116 >   embedded XML in INSERT statements and to support interactive sources in addition
117 >   to non-interactive data sources such as files.
118 >
119 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
120 >
121 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
122 >   SET SQL DIALECT
123 >   SET TERM
124 >   SET AUTODDL
125 >   SET BAIL
126 >   SET ECHO
127 >   SET COUNT
128 >   SET STATS
129 >   SET NAMES <character set>
130 >
131 > 10. IBVersion unit added to hold current IBX Version Number information.
132 >
133 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
134 >    and domain definitions.
135 >
136 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
137 >    fully supported.
138 >
139 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
140 >
141 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

144 >
145 > See also doc/IBX4LazarusGuide.pdf for important information on
146 > upgrading to IBX2.
147 >
148 > 1. Size property of TIBStringField is now the width in characters of the field
149 >   and not the byte length. This applies only to multi-byte character sets such
150 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
151 >   code is not recognised as a bug and hence this change to align the behaviour.
152 >   The TStringField change is expected in fpc 3.2.0.
153 >
154 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
155 >   true (default) then Size property value saved in the lfm is ignored. Size is
156 >   always set from the dynamic information read from the database. It is unclear
157 >   why anyone would want to override this and set Size to false.
158 >
159 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
160 >   block.
161 >
162 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
163 >   exist when an attempt is made to connect to it (run time only) then an attempt
164 >   is made to create the database.
165 >
166 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
167 >   has been successfully created as a result of a call to CreateDatabase or when
168 >   creating a database after it was found not to exist.
169 >
170 > 6.  DBControlGrid: a race condition could result in the wrong row image being
171 >    written to the cache. This has been avoided by a trip round the message
172 >    loop before rendering the row image.
173 >
174 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
175 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
176 >    known to risk corrupt rendering of row images when the control is first
177 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
178 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
179 >
180 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
181 >    a TDateEdit control located on an editor panel.
182 >
183 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
184 >
185 > 10. DBControlGrid: Removed memory leak when updating rows.
186 >
187 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
188 >

190 >
191 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
192 >   when target codepage is CP_NONE. This is a workaround for
193 >   http://bugs.freepascal.org/view.php?id=30622.
194 >
195 > 2. DBLog option removed from TIBStatisticalService - not supported by server
196 >   since Firebird 1.5.
197 >
198 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
199 >   similar.
200 >
201 > 4. IBCodePage: updated mapping between codepages and character id.
202 >
203 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
204 >   Firebird. Character sets with a char width of two are not UTF16.
205 >
206 > 6. Strings received from the database are now always transliterated into UTF8
207 >   regardless of the database character set or connection character set. This
208 >   is for compatibility with the LCL.
209 >

211  
212   1. IBBlob: Defer reading of blob until read method called. This avoids having to
213     read in an entire blob just to get the size of the blob. General performance
