# Line 1 | Line 1
1 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
2 +
3 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
4 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
5 +
6 + 2. TIBSQL: Batch Update/Insert support added.
7 +
8 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
9 +   is no longer automatically converted to upper case when it is syntactically a
10 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
11 +   as CREATE PROCEDURE "iCASE".
12 +
13 +   There could be a backwards compatibility issue when the StoredProcName was entered
14 +   manually at design time. That is not selected from the drop down list. If the
15 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
16 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
17 +   ensure that the value of the StoredProcName is all upper case, unless it was
18 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
19 +   quotes).
20 +
21 +   Note that when a stored procedure name was declared delimited in double quotes,
22 +   as in the first example above, the value of the StoredProcName property must not
23 +   include the delimiters (double quotes).
24 +
25 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
26 +   upgrade.conf was not found. This replaces silently ignoring the problem.
27 +
28 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
29 +   'Version.%.3d' and is used to generate the section header names (for a given
30 +   version no.) in the upgrade.conf file.
31 +
32 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
33 +
34 + 1. -c command line option added to fbsql example program. Used to set connection
35 +   character set.
36 +
37 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
38 +
39 + 1. Firebird 4 support added.
40 +
41 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
42 +   extended precision NUMERIC fields are supported.
43 +
44 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
45 +
46 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
47 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
48 +
49 + 5. IBExtract now supports FB4 enhancements:
50 +   - new data types as above
51 +   - Identity column extensions
52 +   - Default user role
53 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
54 +   - Internal Functions
55 +
56 + 6. IBExtract: new event: OnExtractLines.
57 +
58 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
59 +
60 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
61 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
62 +
63 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
64 +   format for rendering a time zone.
65 +
66 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
67 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
68 +
69 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
70 +    IIBGUIInterface and IIBTimerInf respectively.
71 +
72 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
73 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
74 +
75 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
76 +    truncated to its fixed character width rather than being right padded with
77 +    white space to the maximum data size.
78 +
79 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
80 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
81 +    also empty.
82 +
83 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
84 +
85 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
86 +    connect string. The database name is extracted from the connect string.
87 +
88 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
89 +
90 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
91 +
92 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
93 +    not being present as required.
94 +
95 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
96 +    version that can be customised to work with other database drivers.
97 +
98 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
99 +    unnecessary CR at end of line on Unix platforms.
100 +
101 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
102 +    seconds in order to reduce risk of message loss.
103 +
104 + 23. ISQLMonitor: read and write count statistics now available via:
105 +      property TIBSQLMonitor.ReadCount;
106 +      IIBSQLMonitorHook.GetWriteCount: integer;
107 +
108 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
109 +
110 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
111 +
112 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
113 +    number of UTF8 characters exceeds the string size then string is truncated
114 +    to the maximum string size. This is  usually a problem with fixed width columns
115 +    right padded with white space.
116 +
117 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
118 +    If SQLFiltered is set then when a dataset is opened, each line in the
119 +    SQLFilterParams property is assumed to be a SQL condition clause and
120 +    ANDed into the Where clause of the SQL Select statement provided as a
121 +    dataset property. Each such SQL condition thus acts as an additional filter
122 +    on the dataset.
123 +
124 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
125 +    side filters).
126 +
127 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
128 +   text matches complete entry.
129 +
130 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
131 +   dataset are active (avoids risk of access violation if master is inactive)
132 +
133 + 6. TIBEvents: Registered property can now be set at design time even if database not open
134 +
135 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
136 +   This should prevent "spillover" of events between sessions.
137 +
138 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
139 +   This should ensure that the internal buffer is set up correctly and avoids
140 +   a duplicate initial row.
141 +
142 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
143 +   That is, the DataSize should be the field size * character set width. The
144 +   value returned by DataSize is now the same as the Dataset buffer size reserved
145 +   for the field.
146 +
147 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
148 +
149 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
150 +    and vice-versa. This may result in an exception being raised (correctly) for
151 +    older programs when using dataset fields added to a form and the database has been
152 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
153 +    In such cases, the field needs to be deleted in the IDE fields editor and then
154 +    added back in.
155 +
156 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
157 +    false if query contains only white space and not just empty.
158 +
159 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
160 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
161 +    is cancelled.
162 +
163 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
164 +    called on a null field.
165 +
166 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
167 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
168 + set.
169 +
170 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
171 +    a cached update is applied and an exception is raised.
172 +
173 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
174 +
175 + 17. Console Mode Local Database support: backup/restore should now work correctly.
176 +
177 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
178 +    possible and an exception raised.
179 +
180 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
181 +    below this version no. and upgrade not possible.
182 +
183 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
184 +
185 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
186 +    not SQL Identifiers are now supported.
187 +
188 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
189 +    passed to the Firebird engine for execution.
190 +
191 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
192 +    is made to scroll back.
193 +
194 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
195 +
196 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
197 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
198 +
199 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
200 +   validated. If no match is found in the list of field names and the database has
201 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
202 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
203 +
204 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
205 +   with fpc 3.2.
206 +
207 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
208 +
209 +
210 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
211 +   and is used to override the default settings in the client side "firebird.conf" This
212 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
213 +   Each line of the string list should be a setting in the same format as "firebird.conf".
214 +   For example "WireCompression = true" in order to request wire compression on the client side.
215 +
216 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
217 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
218 +   also require a compatible setting in the server side "firebird.conf". For example
219 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
220 +   compression to be used.
221 +
222 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
223 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
224 +   ibx/examples/dbinfo for examples of how to display this information.
225 +
226 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
227 +   is a "convenience" property. If set the "WireCompression=true" is added to the
228 +   ConfigOverrides. If unchecked then this setting is removed.
229 +
230 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
231 +   not "INT64".
232 +
233 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
234 +   These are:
235 +    property TimestampFormat: string;
236 +    property DateFormat: string;
237 +    property TimeFormat: string;
238 +
239 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
240 +   DATETIME and TIME. The format strings use the standard FPC date/time format
241 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
242 +
243 +   If any of the above properties are set to an empty string, then the locale default
244 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
245 +   locale default is extended by appending '.zzz' to include milliseconds.
246 +
247 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
248 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
249 +
250 + 5. New published property for TIBCSVDataOut:
251 +     property QuoteStrings: boolean (default true)
252 +
253 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
254 +   used to delimit each and every string in the output.
255 +
256 + 6. New published properties for TIBCSVDataOut:
257 +    property FieldSeparator: string;
258 +    property HeaderSeparator: string;
259 +
260 +   Respectively, these provide the separator character(s) used to separate fields
261 +   in data and header rows. Both default to ','.
262 +
263 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
264 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
265 +    property OnFormatTextString;
266 +
267 +   This event handler can be used to process text strings before they are included
268 +   in the output e.g. to replace unprintable characters with alternative strings.
269 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
270 +
271 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
272 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
273 +   and without raising and exception if it does not.
274 +
275 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
276 +   consistency with SQL queries.
277 +
278 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
279 +    When true, SQL statement parameter names are parsed case sensitive. Note for
280 +    TIBDataSet only applies to Select query.
281 +
282 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
283 +    an IDE exception.
284 +
285 + 12. LocalDBSupport: initial database creation should now work correctly
286 +    when the schema source is an sql file.
287 +
288 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
289 +    when defined, this handler will be called by the internal TIBXScript during
290 +    initial database creation when the schema source is an sql file and may be used
291 +    to provide a visual indication of progress in console mode.
292 +
293 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
294 +    to true while a new local database is being created and its schema populated.
295 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
296 +    when the database is disconnected/connected during the create DB procedure.
297 +
298 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
299 +    are now always ignored and replaced by the user name and password provided as
300 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
301 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
302 +    completely ignored if this property is true.
303 +
304 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
305 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
306 +    ImageIndex and SelectImageIndex values on AddNode.
307 +
308 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
309 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
310 +    the same database connection.
311 +
312 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
313 +    if provided, this should be an conditional SQL expression suitable for
314 +    including in an SQL Select statement "where" clause. If non-empty and the
315 +    "Filtered" property is true then the SQL expression provided as the value of
316 +    the "Filter" property is "ANDed" with any existing condition statement
317 +    in the SQL statement's "Where" clause.
318 +
319 +    If the "Filter" property is set at run time, the "Filtered" property is true
320 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
321 +
322 +    The "Filter" condition may include IBX style parameters. In which case, their
323 +    value must be set by the dataset's "OnBeforeOpen" event handler.
324 +
325 +    This is a public property for TIBDataSet and TIBQuery query and intended for
326 +    use at run time.
327 +
328 +    Note: The property is a published property of TIBTable. The TIBTable functionality
329 +    is unaffected by this change.
330 +
331 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
332 +
333 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
334 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
335 +   mode apps.
336 +
337 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
338 +   statement. This avoids problems if "Execute Block" is used as the Query.
339 +
340 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
341 +   internal SQL tokeniser routines.
342 +
343 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
344 +   as a select statement, with or without CTEs.
345 +
346 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
347 +
348 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
349 +   internal SQL tokeniser routines.
350 +
351 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
352 +    being raised for valid set statements processed by a data formatter.
353 +
354 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
355 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
356 +   the path of the Firebird Library used by the database/services connection.
357 +
358 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
359 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
360 +   services connection.
361 +
362 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
363 +   or param name is not a valid SQL identifier.
364 +
365 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
366 +    view of whether the text box should be editable when no DataSource is specified.
367 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
368 +    ReadOnly is false, the text box is editable when no DataSource is specified.
369 +
370 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
371 +    the FBLIB environment variable. If you do not want to permit this then you
372 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
373 +    this setting.
374 +

376 +
377 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
378 +   Utf8EscapeControlChars
379 +
