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 >
228 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
229 >
230 >
231 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
232 >   and is used to override the default settings in the client side "firebird.conf" This
233 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
234 >   Each line of the string list should be a setting in the same format as "firebird.conf".
235 >   For example "WireCompression = true" in order to request wire compression on the client side.
236 >
237 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
238 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
239 >   also require a compatible setting in the server side "firebird.conf". For example
240 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
241 >   compression to be used.
242 >
243 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
244 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
245 >   ibx/examples/dbinfo for examples of how to display this information.
246 >
247 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
248 >   is a "convenience" property. If set the "WireCompression=true" is added to the
249 >   ConfigOverrides. If unchecked then this setting is removed.
250 >
251 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
252 >   not "INT64".
253 >
254 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
255 >   These are:
256 >    property TimestampFormat: string;
257 >    property DateFormat: string;
258 >    property TimeFormat: string;
259 >
260 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
261 >   DATETIME and TIME. The format strings use the standard FPC date/time format
262 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
263 >
264 >   If any of the above properties are set to an empty string, then the locale default
265 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
266 >   locale default is extended by appending '.zzz' to include milliseconds.
267 >
268 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
269 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
270 >
271 > 5. New published property for TIBCSVDataOut:
272 >     property QuoteStrings: boolean (default true)
273 >
274 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
275 >   used to delimit each and every string in the output.
276 >
277 > 6. New published properties for TIBCSVDataOut:
278 >    property FieldSeparator: string;
279 >    property HeaderSeparator: string;
280 >
281 >   Respectively, these provide the separator character(s) used to separate fields
282 >   in data and header rows. Both default to ','.
283 >
284 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
285 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
286 >    property OnFormatTextString;
287 >
288 >   This event handler can be used to process text strings before they are included
289 >   in the output e.g. to replace unprintable characters with alternative strings.
290 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
291 >
292 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
293 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
294 >   and without raising and exception if it does not.
295 >
296 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
297 >   consistency with SQL queries.
298 >
299 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
300 >    When true, SQL statement parameter names are parsed case sensitive. Note for
301 >    TIBDataSet only applies to Select query.
302 >
303 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
304 >    an IDE exception.
305 >
306 > 12. LocalDBSupport: initial database creation should now work correctly
307 >    when the schema source is an sql file.
308 >
309 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
310 >    when defined, this handler will be called by the internal TIBXScript during
311 >    initial database creation when the schema source is an sql file and may be used
312 >    to provide a visual indication of progress in console mode.
313 >
314 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
315 >    to true while a new local database is being created and its schema populated.
316 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
317 >    when the database is disconnected/connected during the create DB procedure.
318 >
319 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
320 >    are now always ignored and replaced by the user name and password provided as
321 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
322 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
323 >    completely ignored if this property is true.
324 >
325 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
326 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
327 >    ImageIndex and SelectImageIndex values on AddNode.
328 >
329 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
330 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
331 >    the same database connection.
332 >
333 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
334 >    if provided, this should be an conditional SQL expression suitable for
335 >    including in an SQL Select statement "where" clause. If non-empty and the
336 >    "Filtered" property is true then the SQL expression provided as the value of
337 >    the "Filter" property is "ANDed" with any existing condition statement
338 >    in the SQL statement's "Where" clause.
339 >
340 >    If the "Filter" property is set at run time, the "Filtered" property is true
341 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
342 >
343 >    The "Filter" condition may include IBX style parameters. In which case, their
344 >    value must be set by the dataset's "OnBeforeOpen" event handler.
345 >
346 >    This is a public property for TIBDataSet and TIBQuery query and intended for
347 >    use at run time.
348 >
349 >    Note: The property is a published property of TIBTable. The TIBTable functionality
350 >    is unaffected by this change.
351 >
352 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
353 >
354 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
355 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
356 >   mode apps.
357 >
358 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
359 >   statement. This avoids problems if "Execute Block" is used as the Query.
360 >
361 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
362 >   internal SQL tokeniser routines.
363 >
364 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
365 >   as a select statement, with or without CTEs.
366 >
367 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
368 >
369 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
370 >   internal SQL tokeniser routines.
371 >
372 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
373 >    being raised for valid set statements processed by a data formatter.
374 >
375 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
376 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
377 >   the path of the Firebird Library used by the database/services connection.
378 >
379 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
380 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
381 >   services connection.
382 >
383 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
384 >   or param name is not a valid SQL identifier.
385 >
386 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
387 >    view of whether the text box should be editable when no DataSource is specified.
388 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
389 >    ReadOnly is false, the text box is editable when no DataSource is specified.
390 >
391 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
392 >    the FBLIB environment variable. If you do not want to permit this then you
393 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
394 >    this setting.

403 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
404 > all previous copies of the IBX source code tree before installing this release.
405 >
406 > The IBX packages used by most users have not changed, with one exception. The
407 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
408 > to use the IBServices unit in your applications, please add the iblegacyServices
409 > to the list of dependencies. To do this, open the Project Inspector and select
410 > Add->New Requirement and select "ibLegacyServices" from the list of available
411 > packages.
412 >
413 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
414 >   the IBServices unit providing what is intended to be a clearer and easier to
415 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
416 >   more information and the guide to "Firebird Service Management Using IBX".
417 >   As indicated above, the legacy services components are still available and
418 >   provided in a separate package. There is no need to update working applications
419 >   using the older versions except for an additional package dependency.
420 >
421 > 2. The IBX packages and source code tree have been re-organised in an attempt to
422 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
423 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
424 >   new set of IBX packages.
425 >
426 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
427 >   updated to use the new Services API components.
428 >
429 > 4. The iblocal package has been updated to use the new Services API components.
430 >
431 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
432 >   TIBXSecurityService. It had been wrongly classified in the previous version
433 >   as a per database configuration item. It is global to a server and hence
434 >   correctly positioned as part of the Security Package. In the DBAdmin example,
435 >   the setting has moved to the mappings page.
436 >
437 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
438 >   are ignored.
439 >
440 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
441 >   closed before the database is dropped. Before and After Disconnect event handlers
442 >   are also fired.
443 >
444 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
445 >   is started and not just the first time.
446 >
447 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
448 >   depenendency with comp type.
449 >
450 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
451 >
452 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
453 >    then this is recognised and not ignored.
454 >
455 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
456 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
457 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
458 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
459 >
460 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
461 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
462 >    counters for the select query. Note: stats accumulate after each fetch from
463 >    the database. To get total query cost after open, call the "Last" method
464 >    and then GetPerfStatistics.
465 >
466 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
467 >
468 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
469 >    in parenthesises.
470 >
471 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
472 >    SQL identifiers are always delimited by double quotes. If false, then they are
473 >    only delimited if the identifier is a reserved word, contains lower case or special
474 >    characters. Set this property to true to retain previous behaviour.
475 >
476 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
477 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
478 >
479 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
480 >       property MasterDetailDelay: integer {defaults to zero}
481 >
482 >    When non-zero and the dataset is a detail table referencing a master table
483 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
484 >    then a synchronisation delay is added (in milliseconds) between the master
485 >    row changing and the detail dataset being re-opened. If the master dataset
486 >    is scrolled before the delay expires then the delay is reset. This can be used
487 >    to avoid performance overheads when scrolling through a large master dataset.
488 >
489 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
490 >    chreads unit must be included in your project. TTimer is not used in order
491 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
492 >
493 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
494 >    with Extract Option eoDatabase.
495 >
496 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
497 >    When a deLayoutChanged event is reported on the ListSource dataset, the
498 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
499 >    relationship with the control's datasource (master).
500 >
501 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
502 >
503 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
504 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
505 >
506 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
507 >    DDL (Firebird 3 and later only).
508 >
509 > 22. TIBLookupComboBox Autocomplete Fixes:
510 >    i. Only appended text is now selected after autocomplete.
511 >    ii. Uppercase keys no longer ignored for autocomplete.
512 >    iii. Retain Prefix case is now honoured correctly.
513 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
514 >        before autocomplete performed. i.e. behaviour now the same as when
515 >        no DataSource assigned.
516 >
517 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
518 >    between SQL statements.
519 >
520 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
521 >    ObjectNames are converted to upper case before matching against metadata object
522 >    names, unless the objectname is delimited by double quotes, in which case, the
523 >    double quotes are removed and the remaining string is used (unmodified) to match
524 >    against the metadata object name.
525 >
526 >    If true then the ObjectName is used as is without modification and matched
527 >    against the metadata object name. No attempt is made to remove double quotes.
528 >
529 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
530 >    with eoTrigger, these extract types can be used to select only Database Triggers,
531 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
532 >
533 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
534 >    statement separate character is now reset to the default (';').
535 >
536 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
537 >
538 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
539 >    a commit or reconnect statement and instead activated only when next SQL statement
540 >    is executed.
541 >
542 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
543 >
544 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
545 >    converting statement to upper case.
546 >
547 > 31. TIBExtract: metadata comments now supported. New published property
548 >    IncludeMetaDataComments (default true). If true then metadata comments included
549 >    in extracted DDL. New Extract Object member eoComments. This may be used with
550 >    ExtractObject method to list all metadata comments.
551 >
552 > 32. TIBExtract: ListObjectNames method added.
553 >
554 > 33. Updated Database component editor to support additional connection string
555 >    types.
556 >
557 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
558 >
559 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
560 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
561 > RELEASE.
562 >
563 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
564 >
565 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
566 >
567 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
568 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
569 >   information). However, this is also a very useful mechanism for returning updated computed by
570 >   column values. Values returned as a result of executing an Insert or Update statement
571 >   replace existing values in the current row for each corresponding column.
572 >
573 >   Previously, if a dataset's select query included read only (computed by) fields then
574 >   an automatic row refresh was performed after an insert or update query had been processed,
575 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
576 >   that an automatic refresh is no longer performed if an insert or update query contains
577 >   a returning clause that updates one or more fields on the current row. A full row
578 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
579 >   field values and the select query contains read only fields. Use of Insert/update
580 >   returning should be significantly more efficient than executing a refresh query.
581 >
582 >   This behaviour change is intended to be backwards compatible and there should be no need to change
583 >   existing programs, other than to improve performance by using the new capability.
584 >
585 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
586 >   they are called when the dataset row is being deleted, there is no value in
587 >   updating the current record from the query result. Instead, a new event handler
588 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
589 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
590 >   by the query. The event handler can then interrogate the query results and
591 >   perform whatever action is necessary. For example to confirm, to the user,
592 >   the deletion of a row with the returned values.
593 >
594 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
595 >   any Computed By or Identity Columns. The IBTables example has been updated to
596 >   illustrate the computation of the employee Full Name on update.
597 >
598 > 5. TIBTable: The GeneratorField property is now published.
599 >
600 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
601 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
602 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
603 >   each Identity column after the insert is executed.
604 >
605 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
606 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
607 >   Insert..Returning clause.
608 >
609 > 8. TIBGenerator: small performance improvement by not preparing query each time
610 >   a new value is generated.
611 >
612 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
613 >
614 > 10. Property editors will now sync table name to a System Table when "Include System
615 >    Tables" is selected and the query is for a System Table.
616 >
617 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
618 >    values are no longer converted to milliseconds from TDateTime and then back again
619 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
620 >
621 > 12. Property Editors handling of Stored Procedures.
622 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
623 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
624 >      query).
625 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
626 >
627 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
628 >    can be used to select a package. If non-empty, the stored procedure name is
629 >    expected to be a stored procedure defined in the specified package and the
630 >    generated SQL will be as required for a stored procedure located in a package.
631 >
632 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
633 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
634 >    which a stored procedure can be selected. With no package name selected, non-package
635 >    stored procedures are listed.
636 >
637 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
638 >    for password on reconnect.
639 >
640 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
641 >    and character set name.
642 >
643 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
644 >    DB info lookups"
645 >
646 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
647 >
648 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
649 >
650 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
651 >    parameters. This stops an exception being raised when the field cannot be
652 >    located in the record buffer.
653 >
654 > 21. Property Editors now automatically include System Tables when opened and when the query table
655 >    is a System Table.
656 >
657 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
658 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
659 >
660 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
661 >    add the SPB item isc_spb_expected_db. This names a database using
662 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
663 >    database. examples/services re-written to illustrate use of "expected_db".
664 >
665 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
666 >    This avoids truncated backups when the server returns a timeout (busy) response.
667 >
668 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
669 >
670 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
671 >    databasenames. These are respectively expanded to the local system's temp directory
672 >    (including trailing delimiter) or to a prescribed data directory (including
673 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
674 >    in the user's home directory. The hidden directory name is either the string returned
675 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
676 >    Under Windows, the directory is the same as the Data Directory as decribed
677 >    above but instead prefixed by the User's application data path. These may be
678 >    used to improve application portability for Personal Databases.
679 >
680 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
681 >    this has not worked for a long time and is not useful either. FieldDefs should be
682 >    managed using the Fields Editor as with any other dataset. To access the fields
683 >    editor for a TIBTable component, double click on the component. The fields editor
684 >    is then displayed.
685 >
686 > 28. TIBDatabaseInfo: new properties/function
687 >     * DateDBCreated (returns date/time database created)
688 >     * TransactionCount (returns no. of active transactions)
689 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
690 >     * PagesFree (Firebird 3 or later)
691 >     * PagesUsed (Firebird 3 or later)
692 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
693 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
694 >
695 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
696 >
697 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
698 >
699 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
700 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
701 >
702 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
703 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
704 >    firing during backup and restore.
705 >
706 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
707 >    for verbose output using the new property "StatisticsRequested".
708 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
709 >
710 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
711 >
712 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
713 >    palette. This uses the online validation feature added in Firebird 2.5. The
714 >    services's properties enable inclusion/exclusion of tables and indexes using
715 >    regular expressions. See.
716 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
717 >
718 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
719 >    option on a database.
720 >
721 > 37. TIBCustomService: Assign method implemented to allow copying of service login
722 >    context between service API components. "Detach" method now only detaches
723 >    service when last reference to the service interface detaches. Tidy up of
724 >    code for SetActive and Attach methods including password hiding.
725 >
726 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
727 >    and used to determine the auth method and protocol used for the connection.
728 >
729 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
730 >    a Create Database Statement generated by IBX.
731 >
732 > 40. All IBServices now have an additional published property "PortNo". This may
733 >    be set to a non-standard port number when necessary. If zero then the default
734 >    port number is used.
735 >
736 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
737 >    and not just the mouse.
738 >
739 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
740 >
741 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
742 >    image index and selected image index for each node to be set from a database field.
743 >
744 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
745 >    then database schema includes grants to all users. If not present then the
746 >    only user grants included are those to User PUBLIC.
747 >
748 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
749 >    and child nodes in dataset.
750 >
751 >
752 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
753 >
754 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
755 >   changes.
756 >
757 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
758 >   Bug could result in truncated multi-byte character set values.
759 >
760 > 3. Changes consequential on moving fbintf character set utility functions from
761 >   IFirebirdAPI to IAttachment.
762 >
763 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
764 >
765 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
766 >   results in autocomplete ignoring prefix text.
767 >
768 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
769 >   entering a new name into the text box.
770 >
771 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
772 >   Firebird rather than recomputing it.
773 >
774 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
775 >   screen centre. Previously some were "poDesigned" which may be inappropriate
776 >   for multi monitor desktops.
777 >
778 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
779 >
780 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
781 >    a transaction and always reset the object.
782 >
783 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
784 >
785 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
786 >
787 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
788 >    to a gbak format archive.
789 >
790 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
791 >
792 > 16. IBLocaldb: Drop database if error creating an empty database.
793 >
794 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
795 >    unless selected node not in current dataset.
796 >
797 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
798 >    to TIBCustomService, and IBlocalDB code tidy up.
799 >
800 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
801 >    behaviour due to uninitialised variable.
802 >
803 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
804 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
805 >
806 > 21. IBSQL: When Database changed ensure that all resources are freed.
807 >
808 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
809 >
810 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
811 >    * Line Wrap on SQL Token boundaries (on user command)
812 >    * auto-complete table names in drop down list of table names
813 >    * Double click on tablename or field name adds to SQL text
814 >
815 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
816 >
817 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
818 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
819 >    workaround for a problem in fpc 3.0.4 win64).
820 >
821 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
822 >
823 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
824 >
825 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
826 >
827 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
828 >   include remote system name.
829 >
830 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
831 >   tables when data included in output.
832 >
833 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
834 >   and timing information to be written to stdout. This may be used to locate
835 >   performance bottlenecks.
836 >
837 > 4. SQLParser: only call "OnChanging" event handler when value is different.
838 >
839 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
840 >
841 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
842 >   that BindFields is called when the query is next activated. Avoids FieldName
843 >   not found error.
844 >
845 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general

854 >
855 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
856 >
857 > 3. TIBExtract: data formatted as Charset set "octets" is now output using

859 >
860 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
861 >   using a simple XML format.
862 >
863 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
864 >   grants to these objects.
865 >
866 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
867 >   dependency problems restoring complex databases.
868 >
869 > 7. TIBXScript: This component has been restructured to allow for the processing of
870 >   embedded XML in INSERT statements and to support interactive sources in addition
871 >   to non-interactive data sources such as files.
872 >
873 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
874 >
875 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
876 >   SET SQL DIALECT
877 >   SET TERM
878 >   SET AUTODDL
879 >   SET BAIL
880 >   SET ECHO
881 >   SET COUNT
882 >   SET STATS

884 >
885 > 10. IBVersion unit added to hold current IBX Version Number information.
886 >
887 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
888 >    and domain definitions.
889 >

899 > See also doc/IBX4LazarusGuide.pdf for important information on
900 > upgrading to IBX2.
901 >
902 > 1. Size property of TIBStringField is now the width in characters of the field
903 >   and not the byte length. This applies only to multi-byte character sets such
904 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
905 >   code is not recognised as a bug and hence this change to align the behaviour.
906 >   The TStringField change is expected in fpc 3.2.0.
907 >
908 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
909 >   true (default) then Size property value saved in the lfm is ignored. Size is
910 >   always set from the dynamic information read from the database. It is unclear
911 >   why anyone would want to override this and set Size to false.
912 >
913 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
914 >   block.
915 >
916 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
917 >   exist when an attempt is made to connect to it (run time only) then an attempt
918 >   is made to create the database.
919 >
920 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
921 >   has been successfully created as a result of a call to CreateDatabase or when
922 >   creating a database after it was found not to exist.
923 >
924 > 6.  DBControlGrid: a race condition could result in the wrong row image being
925 >    written to the cache. This has been avoided by a trip round the message
926 >    loop before rendering the row image.
927 >
928 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
929 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
930 >    known to risk corrupt rendering of row images when the control is first
931 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
932 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
933 >
934 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
935 >    a TDateEdit control located on an editor panel.
936 >
937 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
938 >
939 > 10. DBControlGrid: Removed memory leak when updating rows.
940 >
941 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

944 >
945 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
946 >   when target codepage is CP_NONE. This is a workaround for
947 >   http://bugs.freepascal.org/view.php?id=30622.
948 >
949 > 2. DBLog option removed from TIBStatisticalService - not supported by server
950 >   since Firebird 1.5.
951 >
952 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
953 >   similar.
954 >
955 > 4. IBCodePage: updated mapping between codepages and character id.
956 >
957 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
958 >   Firebird. Character sets with a char width of two are not UTF16.
959 >
960 > 6. Strings received from the database are now always transliterated into UTF8
961 >   regardless of the database character set or connection character set. This
962 >   is for compatibility with the LCL.
963 >

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