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