1 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
2 >
3 > 1. Firebird 4 support added.
4 >
5 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6 >   extended precision NUMERIC fields are supported.
7 >
8 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9 >
10 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12 >
13 > 5. IBExtract now supports FB4 enhancements:
14 >   - new data types as above
15 >   - Identity column extensions
16 >   - Default user role
17 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18 >   - Internal Functions
19 >
20 > 6. IBExtract: new event: OnExtractLines.
21 >
22 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23 >
24 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
25 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26 >
27 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28 >   format for rendering a time zone.
29 >
30 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
32 >
33 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34 >    IIBGUIInterface and IIBTimerInf respectively.
35 >
36 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
38 >
39 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40 >    truncated to its fixed character width rather than being right padded with
41 >    white space to the maximum data size.
42 >
43 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
44 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
45 >    also empty.
46 >
47 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48 >
49 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
50 >    connect string. The database name is extracted from the connect string.
51 >
52 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53 >
54 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55 >
56 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57 >    not being present as required.
58 >
59 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60 >    version that can be customised to work with other database drivers.
61 >
62 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
63 >    unnecessary CR at end of line on Unix platforms.
64 >
65 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
66 >    seconds in order to reduce risk of message loss.
67 >
68 > 23. ISQLMonitor: read and write count statistics now available via:
69 >      property TIBSQLMonitor.ReadCount;
70 >      IIBSQLMonitorHook.GetWriteCount: integer;
71 >
72 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
73 >
74 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
75 >
76 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
77 >    number of UTF8 characters exceeds the string size then string is truncated
78 >    to the maximum string size. This is  usually a problem with fixed width columns
79 >    right padded with white space.
80 >
81 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
82 >    If SQLFiltered is set then when a dataset is opened, each line in the
83 >    SQLFilterParams property is assumed to be a SQL condition clause and
84 >    ANDed into the Where clause of the SQL Select statement provided as a
85 >    dataset property. Each such SQL condition thus acts as an additional filter
86 >    on the dataset.
87 >
88 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
89 >    side filters).
90 >
91 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
92 >   text matches complete entry.
93 >
94 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
95 >   dataset are active (avoids risk of access violation if master is inactive)
96 >
97 > 6. TIBEvents: Registered property can now be set at design time even if database not open
98 >
99 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
100 >   This should prevent "spillover" of events between sessions.
101 >
102 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
103 >   This should ensure that the internal buffer is set up correctly and avoids
104 >   a duplicate initial row.
105 >
106 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
107 >   That is, the DataSize should be the field size * character set width. The
108 >   value returned by DataSize is now the same as the Dataset buffer size reserved
109 >   for the field.
110 >
111 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
112 >
113 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
114 >    and vice-versa. This may result in an exception being raised (correctly) for
115 >    older programs when using dataset fields added to a form and the database has been
116 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
117 >    In such cases, the field needs to be deleted in the IDE fields editor and then
118 >    added back in.
119 >
120 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
121 >    false if query contains only white space and not just empty.
122 >
123 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
124 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
125 >    is cancelled.
126 >
127 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
128 >    called on a null field.
129 >
130 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
131 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
132 > set.
133 >
134 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
135 >    a cached update is applied and an exception is raised.
136 >
137 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
138 >
139 > 17. Console Mode Local Database support: backup/restore should now work correctly.
140 >
141 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
142 >    possible and an exception raised.
143 >
144 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
145 >    below this version no. and upgrade not possible.
146 >
147 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
148 >
149 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
150 >    not SQL Identifiers are now supported.
151 >
152 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
153 >    passed to the Firebird engine for execution.
154 >
155 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
156 >    is made to scroll back.
157 >
158 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
159 >
160 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
161 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
162 >
163 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
164 >   validated. If no match is found in the list of field names and the database has
165 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
166 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
167 >
168 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
169 >   with fpc 3.2.
170 >
171 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
172 >
173 >
174 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
175 >   and is used to override the default settings in the client side "firebird.conf" This
176 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
177 >   Each line of the string list should be a setting in the same format as "firebird.conf".
178 >   For example "WireCompression = true" in order to request wire compression on the client side.
179 >
180 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
181 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
182 >   also require a compatible setting in the server side "firebird.conf". For example
183 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
184 >   compression to be used.
185 >
186 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
187 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
188 >   ibx/examples/dbinfo for examples of how to display this information.
189 >
190 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
191 >   is a "convenience" property. If set the "WireCompression=true" is added to the
192 >   ConfigOverrides. If unchecked then this setting is removed.
193 >
194 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
195 >   not "INT64".
196 >
197 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
198 >   These are:
199 >    property TimestampFormat: string;
200 >    property DateFormat: string;
201 >    property TimeFormat: string;
202 >
203 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
204 >   DATETIME and TIME. The format strings use the standard FPC date/time format
205 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
206 >
207 >   If any of the above properties are set to an empty string, then the locale default
208 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
209 >   locale default is extended by appending '.zzz' to include milliseconds.
210 >
211 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
212 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
213 >
214 > 5. New published property for TIBCSVDataOut:
215 >     property QuoteStrings: boolean (default true)
216 >
217 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
218 >   used to delimit each and every string in the output.
219 >
220 > 6. New published properties for TIBCSVDataOut:
221 >    property FieldSeparator: string;
222 >    property HeaderSeparator: string;
223 >
224 >   Respectively, these provide the separator character(s) used to separate fields
225 >   in data and header rows. Both default to ','.
226 >
227 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
228 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
229 >    property OnFormatTextString;
230 >
231 >   This event handler can be used to process text strings before they are included
232 >   in the output e.g. to replace unprintable characters with alternative strings.
233 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
234 >
235 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
236 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
237 >   and without raising and exception if it does not.
238 >
239 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
240 >   consistency with SQL queries.
241 >
242 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
243 >    When true, SQL statement parameter names are parsed case sensitive. Note for
244 >    TIBDataSet only applies to Select query.
245 >
246 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
247 >    an IDE exception.
248 >
249 > 12. LocalDBSupport: initial database creation should now work correctly
250 >    when the schema source is an sql file.
251 >
252 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
253 >    when defined, this handler will be called by the internal TIBXScript during
254 >    initial database creation when the schema source is an sql file and may be used
255 >    to provide a visual indication of progress in console mode.
256 >
257 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
258 >    to true while a new local database is being created and its schema populated.
259 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
260 >    when the database is disconnected/connected during the create DB procedure.
261 >
262 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
263 >    are now always ignored and replaced by the user name and password provided as
264 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
265 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
266 >    completely ignored if this property is true.
267 >
268 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
269 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
270 >    ImageIndex and SelectImageIndex values on AddNode.
271 >
272 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
273 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
274 >    the same database connection.
275 >
276 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
277 >    if provided, this should be an conditional SQL expression suitable for
278 >    including in an SQL Select statement "where" clause. If non-empty and the
279 >    "Filtered" property is true then the SQL expression provided as the value of
280 >    the "Filter" property is "ANDed" with any existing condition statement
281 >    in the SQL statement's "Where" clause.
282 >
283 >    If the "Filter" property is set at run time, the "Filtered" property is true
284 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
285 >
286 >    The "Filter" condition may include IBX style parameters. In which case, their
287 >    value must be set by the dataset's "OnBeforeOpen" event handler.
288 >
289 >    This is a public property for TIBDataSet and TIBQuery query and intended for
290 >    use at run time.
291 >
292 >    Note: The property is a published property of TIBTable. The TIBTable functionality
293 >    is unaffected by this change.
294 >
