1 > IBX Change Log  version (2.4-3 Build 12857) Wed, 20 Oct 2021 15:12:27 +0100
2 >
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.
6 >
7 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 >   hence will correctly detect end of the outer containing block when the block
9 >   contains a SELECT ... CASE ... END construct.
10 >
11 > 3. IBExtract: some further tidying up to remove extraneous white space.
12 >
13 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
14 >   errors when extra elements are added to DB.TFieldType.
15 >
16 > 5. IBUpdate: updated to reflect changes to ISQLParam.
17 >
18 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
19 >
20 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
21 >
22 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
23 >
24 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
25 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
26 >
27 > 2. TIBSQL: Batch Update/Insert support added.
28 >
29 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
30 >   is no longer automatically converted to upper case when it is syntactically a
31 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
32 >   as CREATE PROCEDURE "iCASE".
33 >
34 >   There could be a backwards compatibility issue when the StoredProcName was entered
35 >   manually at design time. That is not selected from the drop down list. If the
36 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
37 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
38 >   ensure that the value of the StoredProcName is all upper case, unless it was
39 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
40 >   quotes).
41 >
42 >   Note that when a stored procedure name was declared delimited in double quotes,
43 >   as in the first example above, the value of the StoredProcName property must not
44 >   include the delimiters (double quotes).
45 >
46 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
47 >   upgrade.conf was not found. This replaces silently ignoring the problem.
48 >
49 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
50 >   'Version.%.3d' and is used to generate the section header names (for a given
51 >   version no.) in the upgrade.conf file.
52 >
53 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
54 >
55 > 1. -c command line option added to fbsql example program. Used to set connection
56 >   character set.
57 >
58 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
59 >
60 > 1. Firebird 4 support added.
61 >
62 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
63 >   extended precision NUMERIC fields are supported.
64 >
65 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
66 >
67 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
68 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
69 >
70 > 5. IBExtract now supports FB4 enhancements:
71 >   - new data types as above
72 >   - Identity column extensions
73 >   - Default user role
74 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
75 >   - Internal Functions
76 >
77 > 6. IBExtract: new event: OnExtractLines.
78 >
79 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
80 >
81 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
82 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
83 >
84 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
85 >   format for rendering a time zone.
86 >
87 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
88 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
89 >
90 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
91 >    IIBGUIInterface and IIBTimerInf respectively.
92 >
93 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
94 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
95 >
96 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
97 >    truncated to its fixed character width rather than being right padded with
98 >    white space to the maximum data size.
99 >
100 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
101 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
102 >    also empty.
103 >
104 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
105 >
106 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
107 >    connect string. The database name is extracted from the connect string.
108 >
109 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
110 >
111 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
112 >
113 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
114 >    not being present as required.
115 >
116 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
117 >    version that can be customised to work with other database drivers.
118 >
119 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
120 >    unnecessary CR at end of line on Unix platforms.
121 >
122 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
123 >    seconds in order to reduce risk of message loss.
124 >
125 > 23. ISQLMonitor: read and write count statistics now available via:
126 >      property TIBSQLMonitor.ReadCount;
127 >      IIBSQLMonitorHook.GetWriteCount: integer;
128 >
129 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
130 >
131 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
132 >
133 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
134 >    number of UTF8 characters exceeds the string size then string is truncated
135 >    to the maximum string size. This is  usually a problem with fixed width columns
136 >    right padded with white space.
137 >
138 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
139 >    If SQLFiltered is set then when a dataset is opened, each line in the
140 >    SQLFilterParams property is assumed to be a SQL condition clause and
141 >    ANDed into the Where clause of the SQL Select statement provided as a
142 >    dataset property. Each such SQL condition thus acts as an additional filter
143 >    on the dataset.
144 >
145 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
146 >    side filters).
147 >
148 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
149 >   text matches complete entry.
150 >
151 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
152 >   dataset are active (avoids risk of access violation if master is inactive)
153 >
154 > 6. TIBEvents: Registered property can now be set at design time even if database not open
155 >
156 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
157 >   This should prevent "spillover" of events between sessions.
158 >
159 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
160 >   This should ensure that the internal buffer is set up correctly and avoids
161 >   a duplicate initial row.
162 >
163 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
164 >   That is, the DataSize should be the field size * character set width. The
165 >   value returned by DataSize is now the same as the Dataset buffer size reserved
166 >   for the field.
167 >
168 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
169 >
170 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
171 >    and vice-versa. This may result in an exception being raised (correctly) for
172 >    older programs when using dataset fields added to a form and the database has been
173 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
174 >    In such cases, the field needs to be deleted in the IDE fields editor and then
175 >    added back in.
176 >
177 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
178 >    false if query contains only white space and not just empty.
179 >
180 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
181 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
182 >    is cancelled.
183 >
184 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
185 >    called on a null field.
186 >
187 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
188 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
189 > set.
190 >
191 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
192 >    a cached update is applied and an exception is raised.
193 >
194 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
195 >
196 > 17. Console Mode Local Database support: backup/restore should now work correctly.
197 >
198 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
199 >    possible and an exception raised.
200 >
201 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
202 >    below this version no. and upgrade not possible.
203 >
204 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
205 >
206 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
207 >    not SQL Identifiers are now supported.
208 >
209 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
210 >    passed to the Firebird engine for execution.
211 >
212 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
213 >    is made to scroll back.
214 >
215 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
216 >
217 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
218 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
219 >
220 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
221 >   validated. If no match is found in the list of field names and the database has
222 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
223 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
224 >
225 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
226 >   with fpc 3.2.
227 >
