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.

381 >
382 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
383 > all previous copies of the IBX source code tree before installing this release.
384 >
385 > The IBX packages used by most users have not changed, with one exception. The
386 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
387 > to use the IBServices unit in your applications, please add the iblegacyServices
388 > to the list of dependencies. To do this, open the Project Inspector and select
389 > Add->New Requirement and select "ibLegacyServices" from the list of available
390 > packages.
391 >
392 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
393 >   the IBServices unit providing what is intended to be a clearer and easier to
394 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
395 >   more information and the guide to "Firebird Service Management Using IBX".
396 >   As indicated above, the legacy services components are still available and
397 >   provided in a separate package. There is no need to update working applications
398 >   using the older versions except for an additional package dependency.
399 >
400 > 2. The IBX packages and source code tree have been re-organised in an attempt to
401 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
402 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
403 >   new set of IBX packages.
404 >
405 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
406 >   updated to use the new Services API components.
407 >
408 > 4. The iblocal package has been updated to use the new Services API components.
409 >
410 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
411 >   TIBXSecurityService. It had been wrongly classified in the previous version
412 >   as a per database configuration item. It is global to a server and hence
413 >   correctly positioned as part of the Security Package. In the DBAdmin example,
414 >   the setting has moved to the mappings page.
415 >
416 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
417 >   are ignored.
418 >
419 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
420 >   closed before the database is dropped. Before and After Disconnect event handlers
421 >   are also fired.
422 >
423 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
424 >   is started and not just the first time.
425 >
426 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
427 >   depenendency with comp type.
428 >
429 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
430 >
431 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
432 >    then this is recognised and not ignored.
433 >
434 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
435 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
436 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
437 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
438 >
439 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
440 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
441 >    counters for the select query. Note: stats accumulate after each fetch from
442 >    the database. To get total query cost after open, call the "Last" method
443 >    and then GetPerfStatistics.
444 >
445 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
446 >
447 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
448 >    in parenthesises.
449 >
450 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
451 >    SQL identifiers are always delimited by double quotes. If false, then they are
452 >    only delimited if the identifier is a reserved word, contains lower case or special
453 >    characters. Set this property to true to retain previous behaviour.
454 >
455 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
456 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
457 >
458 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
459 >       property MasterDetailDelay: integer {defaults to zero}
460 >
461 >    When non-zero and the dataset is a detail table referencing a master table
462 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
463 >    then a synchronisation delay is added (in milliseconds) between the master
464 >    row changing and the detail dataset being re-opened. If the master dataset
465 >    is scrolled before the delay expires then the delay is reset. This can be used
466 >    to avoid performance overheads when scrolling through a large master dataset.
467 >
468 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
469 >    chreads unit must be included in your project. TTimer is not used in order
470 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
471 >
472 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
473 >    with Extract Option eoDatabase.
474 >
475 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
476 >    When a deLayoutChanged event is reported on the ListSource dataset, the
477 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
478 >    relationship with the control's datasource (master).
479 >
480 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
481 >
482 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
483 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
484 >
485 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
486 >    DDL (Firebird 3 and later only).
487 >
488 > 22. TIBLookupComboBox Autocomplete Fixes:
489 >    i. Only appended text is now selected after autocomplete.
490 >    ii. Uppercase keys no longer ignored for autocomplete.
491 >    iii. Retain Prefix case is now honoured correctly.
492 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
493 >        before autocomplete performed. i.e. behaviour now the same as when
494 >        no DataSource assigned.
495 >
496 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
497 >    between SQL statements.
498 >
499 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
500 >    ObjectNames are converted to upper case before matching against metadata object
501 >    names, unless the objectname is delimited by double quotes, in which case, the
502 >    double quotes are removed and the remaining string is used (unmodified) to match
503 >    against the metadata object name.
504 >
505 >    If true then the ObjectName is used as is without modification and matched
506 >    against the metadata object name. No attempt is made to remove double quotes.
507 >
508 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
509 >    with eoTrigger, these extract types can be used to select only Database Triggers,
510 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
511 >
512 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
513 >    statement separate character is now reset to the default (';').
514 >
515 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
516 >
517 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
518 >    a commit or reconnect statement and instead activated only when next SQL statement
519 >    is executed.
520 >
521 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
522 >
523 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
524 >    converting statement to upper case.
525 >
526 > 31. TIBExtract: metadata comments now supported. New published property
527 >    IncludeMetaDataComments (default true). If true then metadata comments included
528 >    in extracted DDL. New Extract Object member eoComments. This may be used with
529 >    ExtractObject method to list all metadata comments.
530 >
531 > 32. TIBExtract: ListObjectNames method added.
532 >
533 > 33. Updated Database component editor to support additional connection string
534 >    types.
535 >
536 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
537 >
538 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
539 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
540 > RELEASE.
541 >
542 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
543 >
544 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
545 >
546 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
547 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
548 >   information). However, this is also a very useful mechanism for returning updated computed by
549 >   column values. Values returned as a result of executing an Insert or Update statement
550 >   replace existing values in the current row for each corresponding column.
551 >
552 >   Previously, if a dataset's select query included read only (computed by) fields then
553 >   an automatic row refresh was performed after an insert or update query had been processed,
554 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
555 >   that an automatic refresh is no longer performed if an insert or update query contains
556 >   a returning clause that updates one or more fields on the current row. A full row
557 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
558 >   field values and the select query contains read only fields. Use of Insert/update
559 >   returning should be significantly more efficient than executing a refresh query.
560 >
561 >   This behaviour change is intended to be backwards compatible and there should be no need to change
562 >   existing programs, other than to improve performance by using the new capability.
563 >
564 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
565 >   they are called when the dataset row is being deleted, there is no value in
566 >   updating the current record from the query result. Instead, a new event handler
567 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
568 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
569 >   by the query. The event handler can then interrogate the query results and
570 >   perform whatever action is necessary. For example to confirm, to the user,
571 >   the deletion of a row with the returned values.
572 >
573 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
574 >   any Computed By or Identity Columns. The IBTables example has been updated to
575 >   illustrate the computation of the employee Full Name on update.
576 >
577 > 5. TIBTable: The GeneratorField property is now published.
578 >
579 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
580 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
581 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
582 >   each Identity column after the insert is executed.
583 >
584 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
585 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
586 >   Insert..Returning clause.
587 >
588 > 8. TIBGenerator: small performance improvement by not preparing query each time
589 >   a new value is generated.
590 >
591 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
592 >
593 > 10. Property editors will now sync table name to a System Table when "Include System
594 >    Tables" is selected and the query is for a System Table.
595 >
596 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
597 >    values are no longer converted to milliseconds from TDateTime and then back again
598 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
599 >
600 > 12. Property Editors handling of Stored Procedures.
601 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
602 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
603 >      query).
604 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
605 >
606 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
607 >    can be used to select a package. If non-empty, the stored procedure name is
608 >    expected to be a stored procedure defined in the specified package and the
609 >    generated SQL will be as required for a stored procedure located in a package.
610 >
611 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
612 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
613 >    which a stored procedure can be selected. With no package name selected, non-package
614 >    stored procedures are listed.
615 >
616 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
617 >    for password on reconnect.
618 >
619 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
620 >    and character set name.
621 >
622 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
623 >    DB info lookups"
624 >
625 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
626 >
627 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
628 >
629 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
630 >    parameters. This stops an exception being raised when the field cannot be
631 >    located in the record buffer.
632 >
633 > 21. Property Editors now automatically include System Tables when opened and when the query table
634 >    is a System Table.
635 >
636 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
637 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
638 >
639 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
640 >    add the SPB item isc_spb_expected_db. This names a database using
641 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
642 >    database. examples/services re-written to illustrate use of "expected_db".
643 >
644 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
645 >    This avoids truncated backups when the server returns a timeout (busy) response.
646 >
647 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
648 >
649 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
650 >    databasenames. These are respectively expanded to the local system's temp directory
651 >    (including trailing delimiter) or to a prescribed data directory (including
652 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
653 >    in the user's home directory. The hidden directory name is either the string returned
654 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
655 >    Under Windows, the directory is the same as the Data Directory as decribed
656 >    above but instead prefixed by the User's application data path. These may be
657 >    used to improve application portability for Personal Databases.
658 >
659 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
660 >    this has not worked for a long time and is not useful either. FieldDefs should be
661 >    managed using the Fields Editor as with any other dataset. To access the fields
662 >    editor for a TIBTable component, double click on the component. The fields editor
663 >    is then displayed.
664 >
665 > 28. TIBDatabaseInfo: new properties/function
666 >     * DateDBCreated (returns date/time database created)
667 >     * TransactionCount (returns no. of active transactions)
668 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
669 >     * PagesFree (Firebird 3 or later)
670 >     * PagesUsed (Firebird 3 or later)
671 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
672 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
673 >
674 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
675 >
676 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
677 >
678 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
679 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
680 >
681 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
682 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
683 >    firing during backup and restore.
684 >
685 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
686 >    for verbose output using the new property "StatisticsRequested".
687 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
688 >
689 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
690 >
691 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
692 >    palette. This uses the online validation feature added in Firebird 2.5. The
693 >    services's properties enable inclusion/exclusion of tables and indexes using
694 >    regular expressions. See.
695 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
696 >
697 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
698 >    option on a database.
699 >
700 > 37. TIBCustomService: Assign method implemented to allow copying of service login
701 >    context between service API components. "Detach" method now only detaches
702 >    service when last reference to the service interface detaches. Tidy up of
703 >    code for SetActive and Attach methods including password hiding.
704 >
705 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
706 >    and used to determine the auth method and protocol used for the connection.
707 >
708 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
709 >    a Create Database Statement generated by IBX.
710 >
711 > 40. All IBServices now have an additional published property "PortNo". This may
712 >    be set to a non-standard port number when necessary. If zero then the default
713 >    port number is used.
714 >
715 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
716 >    and not just the mouse.
717 >
718 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
719 >
720 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
721 >    image index and selected image index for each node to be set from a database field.
722 >
723 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
724 >    then database schema includes grants to all users. If not present then the
725 >    only user grants included are those to User PUBLIC.
726 >
727 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
728 >    and child nodes in dataset.
729 >
730 >
731 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
732 >
733 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
734 >   changes.
735 >
736 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
737 >   Bug could result in truncated multi-byte character set values.
738 >
739 > 3. Changes consequential on moving fbintf character set utility functions from
740 >   IFirebirdAPI to IAttachment.
741 >
742 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
743 >
744 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
745 >   results in autocomplete ignoring prefix text.
746 >
747 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
748 >   entering a new name into the text box.
749 >
750 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
751 >   Firebird rather than recomputing it.
752 >
753 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
754 >   screen centre. Previously some were "poDesigned" which may be inappropriate
755 >   for multi monitor desktops.
756 >
757 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
758 >
759 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
760 >    a transaction and always reset the object.
761 >
762 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
763 >
764 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
765 >
766 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
767 >    to a gbak format archive.
768 >
769 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
770 >
771 > 16. IBLocaldb: Drop database if error creating an empty database.
772 >
773 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
774 >    unless selected node not in current dataset.
775 >
776 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
777 >    to TIBCustomService, and IBlocalDB code tidy up.
778 >
779 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
780 >    behaviour due to uninitialised variable.
781 >
782 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
783 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
784 >
785 > 21. IBSQL: When Database changed ensure that all resources are freed.
786 >
787 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
788 >
789 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
790 >    * Line Wrap on SQL Token boundaries (on user command)
791 >    * auto-complete table names in drop down list of table names
792 >    * Double click on tablename or field name adds to SQL text
793 >
794 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
795 >
796 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
797 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
798 >    workaround for a problem in fpc 3.0.4 win64).
799 >
800 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
801 >
802 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
803 >
804 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
805 >
806 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
807 >   include remote system name.
808 >
809 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
810 >   tables when data included in output.
811 >
812 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
813 >   and timing information to be written to stdout. This may be used to locate
814 >   performance bottlenecks.
815 >
816 > 4. SQLParser: only call "OnChanging" event handler when value is different.
817 >
818 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
819 >
820 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
821 >   that BindFields is called when the query is next activated. Avoids FieldName
822 >   not found error.
823 >
824 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
825 >   purpose and allows the programmer to define any action they want for Update, Insert
826 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
827 >   filtering of updates, or use of statements such as Grant or Revoke instead of
828 >   normal DML. See User Manual for more information.
829 >
830 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
831 >
832 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
833 >
834 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
835 >
836 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
837 >   hexadecimal notation.
838 >
839 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
840 >   using a simple XML format.
841 >
842 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
843 >   grants to these objects.
844 >
845 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
846 >   dependency problems restoring complex databases.
847 >
848 > 7. TIBXScript: This component has been restructured to allow for the processing of

850 >   to non-interactive data sources such as files.
851 >
852 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
853 >
854 > 9. TIBXScript: ISQL compatiable Set statements are now supported:

858 >   SET BAIL
859 >   SET ECHO
860 >   SET COUNT
861 >   SET STATS
862 >   SET NAMES <character set>
863 >
864 > 10. IBVersion unit added to hold current IBX Version Number information.
865 >
866 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
867 >    and domain definitions.
868 >
869 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
870 >    fully supported.
871 >
872 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
873 >
874 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

877 >
878 > See also doc/IBX4LazarusGuide.pdf for important information on
879 > upgrading to IBX2.
880 >
881 > 1. Size property of TIBStringField is now the width in characters of the field
882 >   and not the byte length. This applies only to multi-byte character sets such
883 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
884 >   code is not recognised as a bug and hence this change to align the behaviour.
885 >   The TStringField change is expected in fpc 3.2.0.
886 >
887 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
888 >   true (default) then Size property value saved in the lfm is ignored. Size is
889 >   always set from the dynamic information read from the database. It is unclear
890 >   why anyone would want to override this and set Size to false.
891 >
892 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
893 >   block.
894 >
895 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
896 >   exist when an attempt is made to connect to it (run time only) then an attempt
897 >   is made to create the database.
898 >
899 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
900 >   has been successfully created as a result of a call to CreateDatabase or when
901 >   creating a database after it was found not to exist.
902 >
903 > 6.  DBControlGrid: a race condition could result in the wrong row image being
904 >    written to the cache. This has been avoided by a trip round the message
905 >    loop before rendering the row image.
906 >
907 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
908 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
909 >    known to risk corrupt rendering of row images when the control is first
910 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
911 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
912 >
913 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
914 >    a TDateEdit control located on an editor panel.
915 >
916 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
917 >
918 > 10. DBControlGrid: Removed memory leak when updating rows.
919 >
920 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

923 >
924 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
925 >   when target codepage is CP_NONE. This is a workaround for
926 >   http://bugs.freepascal.org/view.php?id=30622.
927 >
928 > 2. DBLog option removed from TIBStatisticalService - not supported by server
929 >   since Firebird 1.5.
930 >
931 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
932 >   similar.
933 >
934 > 4. IBCodePage: updated mapping between codepages and character id.
935 >
936 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
937 >   Firebird. Character sets with a char width of two are not UTF16.
938 >
939 > 6. Strings received from the database are now always transliterated into UTF8
940 >   regardless of the database character set or connection character set. This
941 >   is for compatibility with the LCL.

943 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
944 >
945 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
946 >   read in an entire blob just to get the size of the blob. General performance
947 >   improvement when opening datasets containing blobs.
948 >
949 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
950 >
951 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
952 >   is now used.
953 >
954 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
955 >   determined.
956 >
957 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
958 >
959 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
960 >   lazarus 1.6.0
961 >
962 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
963 >   compilation error.

966 >
967 > 1. No character set specified for connection: when a text blob is retrieved, the
968 >  character set is determined by looking up the native character set using then
969 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
970 >  set as the connection.
971 >
972 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
973 >   for Login Dialog returing a change to the database path.
974 >
975 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
976 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
977 >   entered value to be saved on a project specific basis (design time only).
978 >
979 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
980 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
981 >   Otherwise, it sets the column text to the selected ListField Value.
982 >
983 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
984 >   column width.
985 >
986 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
987 >   and a case insensitive search is requested.
988 >
989 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
990 >   or column ListSource.
991 >
992 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
993 >   unprepare) when closing and the text has not changed.
994 >
995 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
996 >   Less likely to cause a cursor re-use error on Windows.
997 >
998 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
999 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1000 >
1001 > 11. TIBTreeView: Guard against nil destination on record changed
1002 >
1003 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1004 >    string type with the code page set to reflect the returned field encoding after
1005 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1006 >    earlier versions.
1007 >
1008 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1009 >    will now result in transliteration to the code page specified for the Firebird driver
1010 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1011 >
1012 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1013 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
1014 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1015 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1016 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1017 >    the GETACP is used to determine the Windows code page.
1018 >
1019 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1020 >    name used as the lc_ctype when the database was opened. Only valid while the
1021 >    Database is connected.
1022 >
1023 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1024 >    id that corresponds to the DefaultCharSetName.

1027 >
1028 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1029 >   path is given and database attach fails due to access permission issues on the
1030 >   temp directory or security database, then the attach is retried with "localhost:"
1031 >   prefixing the databasename. This should avoid problems when the database has to
1032 >   be accessed by a local (e.g. classic) server and libfbembed is used.
1033 >
1034 > 2. Windows: revised search order for Firebird DLL:
1035 >     i.   The Firebird Embedded Server in the application Directory.
1036 >     ii.  If the FIREBIRD environment variable is set then the directory this
1037 >          points to is searched for the FB Client DLL and then then underlying
1038 >          "bin" directory.
1039 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1040 >          is used to locate the Firebird installation directory and the underlying
1041 >          "bin" directory is searched for the FB Client DLL.
1042 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1043 >          are searched for the FB Client DLL.
1044 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
1045 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1046 >
1047 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1048 >   See doc/readme.scriptengine and example applications.
1049 >
1050 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1051 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1052 >   See dpc/readme.localdatabase and example applications.
1053 >
1054 > 5. IBDynamicGrid: Reordering on column header click should now also work for
1055 >   dynamic columns.
1056 >
1057 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1058 >   between incrementing/decrementing the lock count and signalling the event.
1059 >

1061 >
1062 > 1.3.2 was never formally released and only made available as beta copies.
1063 >
1064 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1065 >
1066 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1067 >
1068 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1069 >
1070 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1071 >   i.e. when it is a calculated field
1072 >
1073 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1074 >   This problem was due to a race condition between recalculating row heights and
1075 >   determining which row was selected by the mouse click. The row height calculation
1076 >   is now deferred by an extra trip round the message loop allowing the row to
1077 >   be always calculated on the current grid layout rather than risking it being
1078 >   calculated on the grid layout after the expanded row has been shrunk.
1079 >
1080 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1081 >   Windows.
1082 >
1083 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1084 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1085 >   to be determined at runtime. See doc/readme.charactersets.html.
1086 >
1087 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1088 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1089 >
1090 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1091 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1092 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1093 >
1094 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1095 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1096 >   implies no truncation.
1097 >
1098 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1099 >
1100 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1101 >   (avoids "Not in Edit Mode" error).
1102 >
1103 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1104 >
1105 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1106 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1107 >
1108 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1109 >
1110 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1111 >
1112 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1113 >
1114 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

1117 >
1118 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
1119 >
1120 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1121 >     problem with row size when exception is called.
1122 >
1123 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1124 >
1125 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1126 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
1127 >
1128 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1129 >     keyed in i.e. when autocomplete not performed
1130 >
1131 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1132 >     console mode applications with all LCL required functions (builtin dialogs and
1133 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1134 >     not included in your project, IBX should compile and link with a console mode program.
1135 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1136 >     console mode application or the IDE will automatically assume that your
1137 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1138 >
1139 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1140 >     to use the built in dialogs and cursor management. IBDialogs is
1141 >     included by default if "ibexpress" is in your project source's "uses" clause.
1142 >     This should be the case for all projects created through the IDE. This is why
1143 >     you do not want to add the ibexpress package to console mode applications. The
1144 >     ibexpressconsolemode package has been created to allow console mode programs
1145 >     to avoid adding LCL dependencies when using IBX, while still having the
1146 >     unit search paths set up correctly.
1147 >
1148 >     Existing users should check to ensure that the "ibexpress" unit is included in
1149 >     each project's source file (*.lpr).
1150 >
1151 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
1152 >     exists, you have to first open the package in the IDE and then close it. This
1153 >     adds it to the most recently accessed packages list. To make it permanently
1154 >     available, add the package name to lazarus' staticpackages.inc file.
1155 >
1156 >         Thanks to Julio Jiménez for suggesting support of console mode.
1157 >
1158 > 7.   SQL Parser can now accept quoted strings that include new lines
1159 >
1160 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1161 >     of text on start of edit. This is particularly useful when tabbing to a
1162 >     column and then inserting text.
1163 >
1164 > 9.   New Examples provided for IB Services and ISQLMonitor.
1165 >
1166 > 10. Fix error when writing to blob streams that recorded only the last buffer
1167 >    write in the blob stream. In most cases, this did not cause a problem as the
1168 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
1169 >    of a graphic type prefix was lost which caused a problem when the image could
1170 >        not be automatically recognised.
1171 >
1172 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1173 >    already open" errors due to random numbers used for the cursor name being identical.
1174 >
1175 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
1176 >    when opening the table and the Primary Key is the last or only column in the
1177 >    table. Thanks to Rick Hoover for the fix.
1178 >
1179 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1180 >    of "UTF-8", and update list of available database character sets. Existing
1181 >    users should check the current lc_ctype setting in their applications.

1183 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1184 >
1185 > 1.  Firebird Services: avoid List Index error when opening a service with an
1186 >    empty Params property.
1187 >
1188 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1189 >    Link now set up in Loaded method - avoids occasional failure to apply
1190 >    SQL markup on initial open.
1191 >
1192 > 3.  "Employees" example performance improvements when scrolling.
1193 >
1194 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1195 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1196 >    random image cached).
1197 >
1198 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
1199 >
1200 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1201 >    even when further rows exist.
1202 >
1203 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1204 >    always be derived from panel height and setting this property can cause confusion.
1205 >    Note for existing projects: to avoid a missing property error at run time,
1206 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
1207 >    in order to remove the property value from the lfm.
1208 >

1210 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1211 >
1212 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1213 >    call Prepare before setting parameter values.
1214 >
1215 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1216 >
1217 > 3.  Code tidyup and more robust handling of dsql information result vector.
1218 >
1219 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
1220 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1221 >    and "AfterExecQuery". The first three are called after the same event is called
1222 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1223 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1224 >    enable monitoring of transaction status changes for a given transaction to be
1225 >    handled in a single place. For example, when a change to the dataset occurs
1226 >    an indicator can be set that shows the user that in order to save changes,
1227 >    the transaction should be committed.  Rather than doing this per dataset, this
1228 >    can now be done per transaction.
1229 >
1230 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1231 >    the dataset is scrolled. However, any changes to the current row are, by default,
1232 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1233 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
1234 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
1235 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1236 >    then IBX will attempt to post any unsaved changes before the dataset is closed
1237 >    (and after the BeforeClose event handler is called). The exception is when the
1238 >    dataset is being closed as a result of a transaction rollback. In this case,
1239 >    no action is taken and any unsaved  changes are discarded. This avoids both
1240 >    unnecessary overhead and the risk that a validation error may occur in the Post
1241 >    raising an exception and thereby preventing a rollback.
1242 >
1243 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1244 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1245 >    width. Display Widths are now corrected by dividing by the max byte width per character.
1246 >    For UTF8 character sets, the byte width is four and hence the Display Width will be

1251 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1252 >
1253 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1254 >    control loses focus. Default Key press default interval reduced to 200ms.
1255 >
1256 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1257 >    when dataset rows are less than visible rows.
1258 >
1259 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1260 >    does not exist or DataSet is empty. More responsive on dataset open. New event
1261 >    OnRestorePosition. Column sort disabled if no header row.
1262 >
1263 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1264 >    while dataset state is dsInsert. Avoids posting errors.
1265 >
1266 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1267 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1268 >
1269 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1270 >
1271 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1272 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1273 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1274 >    always "posts" the current record regardless or whether or not it may be more appropriate
1275 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1276 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1277 >    as the first action of the "Post" method and allows the handler to convert the Post
1278 >    into a Cancel if that is the appropriate action on moving to a different row. This is
1279 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1280 >    raised here, but it may still be more appropriate to validate a post and signal
1281 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1282 >
1283 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
1284 >    separated list. Each library name on the list is tried in turn, in left to right
1285 >    order with the first found being used as the firebird library. By default, on Linux,
1286 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1287 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1288 >
1289 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1290 >    then it will still attempt to access the database via the Firebird Server and will
1291 >    require a username and password. If only the pathname is given, then the username
1292 >    and password should be omitted and the unix file permissions are used to grant
1293 >    access.

1295 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1296 >
1297 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1298 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1299 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1300 >    corresponds to a row of the linked DataSource. Any data aware control on the
1301 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1302 >
1303 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1304 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1305 >   takes place during database access. This may be useful when there are performance issues with
1306 >   the change of cursor. Setting the property to false suppresses the change of cursor.
1307 >
1308 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1309 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1310 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1311 >   making all changes permanent immediately rather than when the transaction is explicitly
1312 >   committed.
1313 >
1314 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1315 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1322 >
1323 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1324 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1325 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
1326 >   complexity.
1327 >
1328 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1329 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1330 >   These are:
1331 >
1332 >   - TIBLookupComboEditBox
1333 >   - TIBDynamicGrid
1334 >   - TIBTreeview
1335 >
1336 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1337 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1338 >   to revise the available list and restrict it to items that are prefixed by the
1339 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
1340 >   newly typed entry to be added to the list dataset and included in the available
1341 >   list items.
1342 >
1343 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
1344 >   - automatic resizing of selected columns to fill the available row length
1345 >   - automatic positioning and sizing of a "totals" control, typically at the
1346 >     column footer, on a per column basis.
1347 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
1348 >     A second click on the same header cell reversed the sort order.
1349 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1350 >     is automatically expanded and a panel superimposed on it. The panel can have any
1351 >     number of child controls, typically data aware controls with the same datasource
1352 >     as the grid allowing for editing of additional fields and more complex editors.
1353 >   - Reselection of the same row following resorting.
1354 >   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1355 >     Its properties are specified on a per column basis and allows for one or more
1356 >     columns to have their values selected from a list provided by a dataset.
1357 >     Autocomplete and autoinsert are also available. The existing picklist editor
1358 >     is unaffected by the extension.
1359 >
1360 >   TIBTreeView is a data aware TCustomTreeView.
1361 >
1362 > 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1363 >   zero scale will no longer return an error. An Int64 will be returned instead.
1364 >
1365 > 4. TIBTransaction now has events for Before and After Transaction End and a new function
1366 >   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1367 >
1368 > 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1369 >   repeated multiple times.
1370 >
1371 > 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1372 >   check used to get in the way of using Stored Procedures, and "Update or Insert"
1373 >   statements.
1374 >
1375 > 7. Insert, Modify and Delete property Editors now support Query Generation from
1376 >   Stored Procedures.
1377 >
1378 > 8. Three new examples illustrate the use of the new IB Controls
1379 >
