1 + IBX Change Log  version (2.5-1 Build nnn) Tue, 6 Dec 2022 23:13:00 +0000
2 +
3 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
4 +
5 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
6 +
7 + 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
8 +
9 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
10 +
11 + 1. TIBTransaction: new properties
12 +    property TransactionID: integer read GetTransactionID;
13 +    property IsReadOnly: boolean read GetIsReadOnly;
14 +    {published}
15 +    property TransactionName: string read FTransactionName write SetTransactionName;
16 +
17 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
18 +   Insert or Update...Returning. This allows blobs and arrays to be returned
19 +   by the statement.
20 +
21 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
22 +
23 + 4. TransactionName initialised to a newly generated GUID if empty.
24 +
25 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
26 +   for the fbintf package's journaling capability. TIBJournal is used to set the
27 +   file path and filename for the journal file and to Enabled (start journaling) and
28 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
29 +   more information, and comments in IBJournal.pas.
30 +
31 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
32 +
33 + 7. Bug fix: blob id no longer set to null on update when blob has not been
34 +   retrieved.
35 +
36 + 8. Row auto refreshed on update/insert if blob or array field updated and field
37 +   not in a returning clause.
38 +
39 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
40 +   buffer overhead and avoids problem when refresh query has a different column
41 +   count to select query i.e. incorrectly changing number of columns.
42 +
43 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
44 +
45 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
46 +    string. Note that the Version property returns an InterBase compatible version string.
47 +
48 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
49 +
50 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
51 +
52 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
53 +   This is for compatibility with Firebird 5 where Update...Returning can return
54 +   a cursor.
55 +
56 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
57 +
58 + 1. Add try-..except check when initially loading library in IDE. This should
59 + ensure that IDE continues to load even when a failure occurs in IBX load
60 + library.
61 +
62 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
63 +   hence will correctly detect end of the outer containing block when the block
64 +   contains a SELECT ... CASE ... END construct.
65 +
66 + 3. IBExtract: some further tidying up to remove extraneous white space.
67 +
68 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
69 +   errors when extra elements are added to DB.TFieldType.
70 +
71 + 5. IBUpdate: updated to reflect changes to ISQLParam.
72 +
73 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
74 +
75 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
76 +
77 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
78 +
79 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
80 +
81 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
82 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
83 +
84 + 2. TIBSQL: Batch Update/Insert support added.
85 +
86 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
87 +   is no longer automatically converted to upper case when it is syntactically a
88 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
89 +   as CREATE PROCEDURE "iCASE".
90 +
91 +   There could be a backwards compatibility issue when the StoredProcName was entered
92 +   manually at design time. That is not selected from the drop down list. If the
93 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
94 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
95 +   ensure that the value of the StoredProcName is all upper case, unless it was
96 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
97 +   quotes).
98 +
99 +   Note that when a stored procedure name was declared delimited in double quotes,
100 +   as in the first example above, the value of the StoredProcName property must not
101 +   include the delimiters (double quotes).
102 +
103 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
104 +   upgrade.conf was not found. This replaces silently ignoring the problem.
105 +
106 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
107 +   'Version.%.3d' and is used to generate the section header names (for a given
108 +   version no.) in the upgrade.conf file.
109 +
110 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
111 +
112 + 1. -c command line option added to fbsql example program. Used to set connection
113 +   character set.
114 +
115 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
116 +
117 + 1. Firebird 4 support added.
118 +
119 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
120 +   extended precision NUMERIC fields are supported.
121 +
122 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
123 +
124 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
125 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
126 +
127 + 5. IBExtract now supports FB4 enhancements:
128 +   - new data types as above
129 +   - Identity column extensions
130 +   - Default user role
131 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
132 +   - Internal Functions
133 +
134 + 6. IBExtract: new event: OnExtractLines.
135 +
136 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
137 +
138 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
139 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
140 +
141 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
142 +   format for rendering a time zone.
143 +
144 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
145 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
146 +
147 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
148 +    IIBGUIInterface and IIBTimerInf respectively.
149 +
150 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
151 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
152 +
153 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
154 +    truncated to its fixed character width rather than being right padded with
155 +    white space to the maximum data size.
156 +
157 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
158 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
159 +    also empty.
160 +
161 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
162 +
163 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
164 +    connect string. The database name is extracted from the connect string.
165 +
166 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
167 +
168 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
169 +
170 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
171 +    not being present as required.
172 +
173 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
174 +    version that can be customised to work with other database drivers.
175 +
176 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
177 +    unnecessary CR at end of line on Unix platforms.
178 +
179 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
180 +    seconds in order to reduce risk of message loss.
181 +
182 + 23. ISQLMonitor: read and write count statistics now available via:
183 +      property TIBSQLMonitor.ReadCount;
184 +      IIBSQLMonitorHook.GetWriteCount: integer;
185 +
186 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
187 +
188 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
189 +
190 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
191 +    number of UTF8 characters exceeds the string size then string is truncated
192 +    to the maximum string size. This is  usually a problem with fixed width columns
193 +    right padded with white space.
194 +
195 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
196 +    If SQLFiltered is set then when a dataset is opened, each line in the
197 +    SQLFilterParams property is assumed to be a SQL condition clause and
198 +    ANDed into the Where clause of the SQL Select statement provided as a
199 +    dataset property. Each such SQL condition thus acts as an additional filter
200 +    on the dataset.
201 +
202 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
203 +    side filters).
204 +
205 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
206 +   text matches complete entry.
207 +
208 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
209 +   dataset are active (avoids risk of access violation if master is inactive)
210 +
211 + 6. TIBEvents: Registered property can now be set at design time even if database not open
212 +
213 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
214 +   This should prevent "spillover" of events between sessions.
215 +
216 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
217 +   This should ensure that the internal buffer is set up correctly and avoids
218 +   a duplicate initial row.
219 +
220 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
221 +   That is, the DataSize should be the field size * character set width. The
222 +   value returned by DataSize is now the same as the Dataset buffer size reserved
223 +   for the field.
224 +
225 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
226 +
227 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
228 +    and vice-versa. This may result in an exception being raised (correctly) for
229 +    older programs when using dataset fields added to a form and the database has been
230 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
231 +    In such cases, the field needs to be deleted in the IDE fields editor and then
232 +    added back in.
233 +
234 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
235 +    false if query contains only white space and not just empty.
236 +
237 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
238 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
239 +    is cancelled.
240 +
241 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
242 +    called on a null field.
243 +
244 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
245 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
246 + set.
247 +
248 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
249 +    a cached update is applied and an exception is raised.
250 +
251 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
252 +
253 + 17. Console Mode Local Database support: backup/restore should now work correctly.
254 +
255 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
256 +    possible and an exception raised.
257 +
258 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
259 +    below this version no. and upgrade not possible.
260 +
261 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
262 +
263 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
264 +    not SQL Identifiers are now supported.
265 +
266 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
267 +    passed to the Firebird engine for execution.
268 +
269 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
270 +    is made to scroll back.
271 +
272 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
273 +
274 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
275 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
276 +
277 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
278 +   validated. If no match is found in the list of field names and the database has
279 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
280 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
281 +
282 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
283 +   with fpc 3.2.
284 +
285 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
286 +
287 +
288 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
289 +   and is used to override the default settings in the client side "firebird.conf" This
290 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
291 +   Each line of the string list should be a setting in the same format as "firebird.conf".
292 +   For example "WireCompression = true" in order to request wire compression on the client side.
293 +
294 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
295 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
296 +   also require a compatible setting in the server side "firebird.conf". For example
297 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
298 +   compression to be used.
299 +
300 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
301 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
302 +   ibx/examples/dbinfo for examples of how to display this information.
303 +
304 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
305 +   is a "convenience" property. If set the "WireCompression=true" is added to the
306 +   ConfigOverrides. If unchecked then this setting is removed.
307 +
308 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
309 +   not "INT64".
310 +
311 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
312 +   These are:
313 +    property TimestampFormat: string;
314 +    property DateFormat: string;
315 +    property TimeFormat: string;
316 +
317 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
318 +   DATETIME and TIME. The format strings use the standard FPC date/time format
319 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
320 +
321 +   If any of the above properties are set to an empty string, then the locale default
322 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
323 +   locale default is extended by appending '.zzz' to include milliseconds.
324 +
325 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
326 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
327 +
328 + 5. New published property for TIBCSVDataOut:
329 +     property QuoteStrings: boolean (default true)
330 +
331 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
332 +   used to delimit each and every string in the output.
333 +
334 + 6. New published properties for TIBCSVDataOut:
335 +    property FieldSeparator: string;
336 +    property HeaderSeparator: string;
337 +
338 +   Respectively, these provide the separator character(s) used to separate fields
339 +   in data and header rows. Both default to ','.
340 +
341 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
342 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
343 +    property OnFormatTextString;
344 +
345 +   This event handler can be used to process text strings before they are included
346 +   in the output e.g. to replace unprintable characters with alternative strings.
347 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
348 +
349 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
350 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
351 +   and without raising and exception if it does not.
352 +
353 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
354 +   consistency with SQL queries.
355 +
356 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
357 +    When true, SQL statement parameter names are parsed case sensitive. Note for
358 +    TIBDataSet only applies to Select query.
359 +
360 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
361 +    an IDE exception.
362 +
363 + 12. LocalDBSupport: initial database creation should now work correctly
364 +    when the schema source is an sql file.
365 +
366 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
367 +    when defined, this handler will be called by the internal TIBXScript during
368 +    initial database creation when the schema source is an sql file and may be used
369 +    to provide a visual indication of progress in console mode.
370 +
371 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
372 +    to true while a new local database is being created and its schema populated.
373 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
374 +    when the database is disconnected/connected during the create DB procedure.
375 +
376 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
377 +    are now always ignored and replaced by the user name and password provided as
378 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
379 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
380 +    completely ignored if this property is true.
381 +
382 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
383 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
384 +    ImageIndex and SelectImageIndex values on AddNode.
385 +
386 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
387 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
388 +    the same database connection.
389 +
390 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
391 +    if provided, this should be an conditional SQL expression suitable for
392 +    including in an SQL Select statement "where" clause. If non-empty and the
393 +    "Filtered" property is true then the SQL expression provided as the value of
394 +    the "Filter" property is "ANDed" with any existing condition statement
395 +    in the SQL statement's "Where" clause.
396 +
397 +    If the "Filter" property is set at run time, the "Filtered" property is true
398 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
399 +
400 +    The "Filter" condition may include IBX style parameters. In which case, their
401 +    value must be set by the dataset's "OnBeforeOpen" event handler.
402 +
403 +    This is a public property for TIBDataSet and TIBQuery query and intended for
404 +    use at run time.
405 +
406 +    Note: The property is a published property of TIBTable. The TIBTable functionality
407 +    is unaffected by this change.
408 +
409 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
410 +
411 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
412 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
413 +   mode apps.
414 +
415 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
416 +   statement. This avoids problems if "Execute Block" is used as the Query.
417 +
418 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
419 +   internal SQL tokeniser routines.
420 +
421 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
422 +   as a select statement, with or without CTEs.
423 +
424 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
425 +
426 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
427 +   internal SQL tokeniser routines.
428 +
429 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
430 +    being raised for valid set statements processed by a data formatter.
431 +
432 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
433 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
434 +   the path of the Firebird Library used by the database/services connection.
435 +
436 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
437 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
438 +   services connection.
439 +
440 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
441 +   or param name is not a valid SQL identifier.
442 +
443 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
444 +    view of whether the text box should be editable when no DataSource is specified.
445 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
446 +    ReadOnly is false, the text box is editable when no DataSource is specified.
447 +
448 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
449 +    the FBLIB environment variable. If you do not want to permit this then you
450 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
451 +    this setting.

454 +
455 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
456 +   Utf8EscapeControlChars
457 +
458 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
459 +
460 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
461 + all previous copies of the IBX source code tree before installing this release.
462 +
463 + The IBX packages used by most users have not changed, with one exception. The
464 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
465 + to use the IBServices unit in your applications, please add the iblegacyServices
466 + to the list of dependencies. To do this, open the Project Inspector and select
467 + Add->New Requirement and select "ibLegacyServices" from the list of available
468 + packages.
469 +
470 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
471 +   the IBServices unit providing what is intended to be a clearer and easier to
472 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
473 +   more information and the guide to "Firebird Service Management Using IBX".
474 +   As indicated above, the legacy services components are still available and
475 +   provided in a separate package. There is no need to update working applications
476 +   using the older versions except for an additional package dependency.
477 +
478 + 2. The IBX packages and source code tree have been re-organised in an attempt to
479 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
480 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
481 +   new set of IBX packages.
482 +
483 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
484 +   updated to use the new Services API components.
485 +
486 + 4. The iblocal package has been updated to use the new Services API components.
487 +
488 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
489 +   TIBXSecurityService. It had been wrongly classified in the previous version
490 +   as a per database configuration item. It is global to a server and hence
491 +   correctly positioned as part of the Security Package. In the DBAdmin example,
492 +   the setting has moved to the mappings page.
493 +
494 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
495 +   are ignored.
496 +
497 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
498 +   closed before the database is dropped. Before and After Disconnect event handlers
499 +   are also fired.
500 +
501 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
502 +   is started and not just the first time.
503 +
504 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
505 +   depenendency with comp type.
506 +
507 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
508 +
509 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
510 +    then this is recognised and not ignored.
511 +
512 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
513 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
514 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
515 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
516 +
517 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
518 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
519 +    counters for the select query. Note: stats accumulate after each fetch from
520 +    the database. To get total query cost after open, call the "Last" method
521 +    and then GetPerfStatistics.
522 +
523 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
524 +
525 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
526 +    in parenthesises.
527 +
528 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
529 +    SQL identifiers are always delimited by double quotes. If false, then they are
530 +    only delimited if the identifier is a reserved word, contains lower case or special
531 +    characters. Set this property to true to retain previous behaviour.
532 +
533 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
534 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
535 +
536 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
537 +       property MasterDetailDelay: integer {defaults to zero}
538 +
539 +    When non-zero and the dataset is a detail table referencing a master table
540 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
541 +    then a synchronisation delay is added (in milliseconds) between the master
542 +    row changing and the detail dataset being re-opened. If the master dataset
543 +    is scrolled before the delay expires then the delay is reset. This can be used
544 +    to avoid performance overheads when scrolling through a large master dataset.
545 +
546 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
547 +    chreads unit must be included in your project. TTimer is not used in order
548 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
549 +
550 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
551 +    with Extract Option eoDatabase.
552 +
553 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
554 +    When a deLayoutChanged event is reported on the ListSource dataset, the
555 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
556 +    relationship with the control's datasource (master).
557 +
558 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
559 +
560 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
561 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
562 +
563 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
564 +    DDL (Firebird 3 and later only).
565 +
566 + 22. TIBLookupComboBox Autocomplete Fixes:
567 +    i. Only appended text is now selected after autocomplete.
568 +    ii. Uppercase keys no longer ignored for autocomplete.
569 +    iii. Retain Prefix case is now honoured correctly.
570 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
571 +        before autocomplete performed. i.e. behaviour now the same as when
572 +        no DataSource assigned.
573 +
574 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
575 +    between SQL statements.
576 +
577 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
578 +    ObjectNames are converted to upper case before matching against metadata object
579 +    names, unless the objectname is delimited by double quotes, in which case, the
580 +    double quotes are removed and the remaining string is used (unmodified) to match
581 +    against the metadata object name.
582 +
583 +    If true then the ObjectName is used as is without modification and matched
584 +    against the metadata object name. No attempt is made to remove double quotes.
585 +
586 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
587 +    with eoTrigger, these extract types can be used to select only Database Triggers,
588 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
589 +
590 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
591 +    statement separate character is now reset to the default (';').
592 +
593 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
594 +
595 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
596 +    a commit or reconnect statement and instead activated only when next SQL statement
597 +    is executed.
598 +
599 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
600 +
601 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
602 +    converting statement to upper case.
603 +
604 + 31. TIBExtract: metadata comments now supported. New published property
605 +    IncludeMetaDataComments (default true). If true then metadata comments included
606 +    in extracted DDL. New Extract Object member eoComments. This may be used with
607 +    ExtractObject method to list all metadata comments.
608 +
609 + 32. TIBExtract: ListObjectNames method added.
610 +
611 + 33. Updated Database component editor to support additional connection string
612 +    types.
613 +
614 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
615 +
616 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
617 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
618 + RELEASE.
619 +
620 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
621 +
622 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
623 +
624 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
625 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
626 +   information). However, this is also a very useful mechanism for returning updated computed by
627 +   column values. Values returned as a result of executing an Insert or Update statement
628 +   replace existing values in the current row for each corresponding column.
629 +
630 +   Previously, if a dataset's select query included read only (computed by) fields then
631 +   an automatic row refresh was performed after an insert or update query had been processed,
632 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
633 +   that an automatic refresh is no longer performed if an insert or update query contains
634 +   a returning clause that updates one or more fields on the current row. A full row
635 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
636 +   field values and the select query contains read only fields. Use of Insert/update
637 +   returning should be significantly more efficient than executing a refresh query.
638 +
639 +   This behaviour change is intended to be backwards compatible and there should be no need to change
640 +   existing programs, other than to improve performance by using the new capability.
641 +
642 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
643 +   they are called when the dataset row is being deleted, there is no value in
644 +   updating the current record from the query result. Instead, a new event handler
645 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
646 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
647 +   by the query. The event handler can then interrogate the query results and
648 +   perform whatever action is necessary. For example to confirm, to the user,
649 +   the deletion of a row with the returned values.
650 +
651 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
652 +   any Computed By or Identity Columns. The IBTables example has been updated to
653 +   illustrate the computation of the employee Full Name on update.
654 +
655 + 5. TIBTable: The GeneratorField property is now published.
656 +
657 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
658 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
659 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
660 +   each Identity column after the insert is executed.
661 +
662 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
663 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
664 +   Insert..Returning clause.
665 +
666 + 8. TIBGenerator: small performance improvement by not preparing query each time
667 +   a new value is generated.
668 +
669 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
670 +
671 + 10. Property editors will now sync table name to a System Table when "Include System
672 +    Tables" is selected and the query is for a System Table.
673 +
674 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
675 +    values are no longer converted to milliseconds from TDateTime and then back again
676 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
677 +
678 + 12. Property Editors handling of Stored Procedures.
679 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
680 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
681 +      query).
682 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
683 +
684 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
685 +    can be used to select a package. If non-empty, the stored procedure name is
686 +    expected to be a stored procedure defined in the specified package and the
687 +    generated SQL will be as required for a stored procedure located in a package.
688 +
689 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
690 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
691 +    which a stored procedure can be selected. With no package name selected, non-package
692 +    stored procedures are listed.
693 +
694 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
695 +    for password on reconnect.
696 +
697 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
698 +    and character set name.
699 +
700 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
701 +    DB info lookups"
702 +
703 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
704 +
705 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
706 +
707 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
708 +    parameters. This stops an exception being raised when the field cannot be
709 +    located in the record buffer.
710 +
711 + 21. Property Editors now automatically include System Tables when opened and when the query table
712 +    is a System Table.
713 +
714 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
715 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
716 +
717 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
718 +    add the SPB item isc_spb_expected_db. This names a database using
719 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
720 +    database. examples/services re-written to illustrate use of "expected_db".
721 +
722 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
723 +    This avoids truncated backups when the server returns a timeout (busy) response.
724 +
725 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
726 +
727 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
728 +    databasenames. These are respectively expanded to the local system's temp directory
729 +    (including trailing delimiter) or to a prescribed data directory (including
730 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
731 +    in the user's home directory. The hidden directory name is either the string returned
732 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
733 +    Under Windows, the directory is the same as the Data Directory as decribed
734 +    above but instead prefixed by the User's application data path. These may be
735 +    used to improve application portability for Personal Databases.
736 +
737 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
738 +    this has not worked for a long time and is not useful either. FieldDefs should be
739 +    managed using the Fields Editor as with any other dataset. To access the fields
740 +    editor for a TIBTable component, double click on the component. The fields editor
741 +    is then displayed.
742 +
743 + 28. TIBDatabaseInfo: new properties/function
744 +     * DateDBCreated (returns date/time database created)
745 +     * TransactionCount (returns no. of active transactions)
746 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
747 +     * PagesFree (Firebird 3 or later)
748 +     * PagesUsed (Firebird 3 or later)
749 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
750 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
751 +
752 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
753 +
754 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
755 +
756 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
757 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
758 +
759 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
760 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
761 +    firing during backup and restore.
762 +
763 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
764 +    for verbose output using the new property "StatisticsRequested".
765 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
766 +
767 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
768 +
769 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
770 +    palette. This uses the online validation feature added in Firebird 2.5. The
771 +    services's properties enable inclusion/exclusion of tables and indexes using
772 +    regular expressions. See.
773 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
774 +
775 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
776 +    option on a database.
777 +
778 + 37. TIBCustomService: Assign method implemented to allow copying of service login
779 +    context between service API components. "Detach" method now only detaches
780 +    service when last reference to the service interface detaches. Tidy up of
781 +    code for SetActive and Attach methods including password hiding.
782 +
783 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
784 +    and used to determine the auth method and protocol used for the connection.
785 +
786 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
787 +    a Create Database Statement generated by IBX.
788 +
789 + 40. All IBServices now have an additional published property "PortNo". This may
790 +    be set to a non-standard port number when necessary. If zero then the default
791 +    port number is used.
792 +
793 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
794 +    and not just the mouse.
795 +
796 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
797 +
798 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
799 +    image index and selected image index for each node to be set from a database field.
800 +
801 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
802 +    then database schema includes grants to all users. If not present then the
803 +    only user grants included are those to User PUBLIC.
804 +
805 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
806 +    and child nodes in dataset.
807 +
808 +
809 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
810 +
811 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
812 +   changes.
813 +
814 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
815 +   Bug could result in truncated multi-byte character set values.
816 +
817 + 3. Changes consequential on moving fbintf character set utility functions from
818 +   IFirebirdAPI to IAttachment.
819 +
820 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
821 +
822 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
823 +   results in autocomplete ignoring prefix text.
824 +
825 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
826 +   entering a new name into the text box.
827 +
828 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
829 +   Firebird rather than recomputing it.
830 +
831 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
832 +   screen centre. Previously some were "poDesigned" which may be inappropriate
833 +   for multi monitor desktops.
834 +
835 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
836 +
837 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
838 +    a transaction and always reset the object.
839 +
840 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
841 +
842 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
843 +
844 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
845 +    to a gbak format archive.
846 +
847 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
848 +
849 + 16. IBLocaldb: Drop database if error creating an empty database.
850 +
851 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
852 +    unless selected node not in current dataset.
853 +
854 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
855 +    to TIBCustomService, and IBlocalDB code tidy up.
856 +
857 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
858 +    behaviour due to uninitialised variable.
859 +
860 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
861 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
862 +
863 + 21. IBSQL: When Database changed ensure that all resources are freed.
864 +
865 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
866 +
867 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
868 +    * Line Wrap on SQL Token boundaries (on user command)
869 +    * auto-complete table names in drop down list of table names
870 +    * Double click on tablename or field name adds to SQL text
871 +
872 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
873 +
874 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
875 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
876 +    workaround for a problem in fpc 3.0.4 win64).
877 +
878 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
879 +
880 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
881 +
882 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
883 +
884 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
885 +   include remote system name.
886 +
887 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
888 +   tables when data included in output.
889 +
890 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
891 +   and timing information to be written to stdout. This may be used to locate
892 +   performance bottlenecks.
893 +
894 + 4. SQLParser: only call "OnChanging" event handler when value is different.
895 +
896 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
897 +
898 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
899 +   that BindFields is called when the query is next activated. Avoids FieldName
900 +   not found error.
901 +
902 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
903 +   purpose and allows the programmer to define any action they want for Update, Insert
904 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
905 +   filtering of updates, or use of statements such as Grant or Revoke instead of
906 +   normal DML. See User Manual for more information.
907 +
908 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
909 +
910 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
911 +
912 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
913 +
914 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
915 +   hexadecimal notation.
916 +
917 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
918 +   using a simple XML format.
919 +
920 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
921 +   grants to these objects.
922 +
923 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
924 +   dependency problems restoring complex databases.
925 +
926 + 7. TIBXScript: This component has been restructured to allow for the processing of
927 +   embedded XML in INSERT statements and to support interactive sources in addition
928 +   to non-interactive data sources such as files.
929 +
930 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
931 +
932 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
933 +   SET SQL DIALECT
934 +   SET TERM
935 +   SET AUTODDL
936 +   SET BAIL
937 +   SET ECHO
938 +   SET COUNT
939 +   SET STATS
940 +   SET NAMES <character set>
941 +
942 + 10. IBVersion unit added to hold current IBX Version Number information.
943 +
944 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
945 +    and domain definitions.
946 +
947 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
948 +    fully supported.
949 +
950 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
951 +
952 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
953 +
954 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
955 +
956 + See also doc/IBX4LazarusGuide.pdf for important information on
957 + upgrading to IBX2.
958 +
959 + 1. Size property of TIBStringField is now the width in characters of the field
960 +   and not the byte length. This applies only to multi-byte character sets such
961 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
962 +   code is not recognised as a bug and hence this change to align the behaviour.
963 +   The TStringField change is expected in fpc 3.2.0.
964 +
965 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
966 +   true (default) then Size property value saved in the lfm is ignored. Size is
967 +   always set from the dynamic information read from the database. It is unclear
968 +   why anyone would want to override this and set Size to false.
969 +
970 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
971 +   block.
972 +
973 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
974 +   exist when an attempt is made to connect to it (run time only) then an attempt
975 +   is made to create the database.
976 +
977 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
978 +   has been successfully created as a result of a call to CreateDatabase or when
979 +   creating a database after it was found not to exist.
980 +
981 + 6.  DBControlGrid: a race condition could result in the wrong row image being
982 +    written to the cache. This has been avoided by a trip round the message
983 +    loop before rendering the row image.
984 +
985 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
986 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
987 +    known to risk corrupt rendering of row images when the control is first
988 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
989 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
990 +
991 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
992 +    a TDateEdit control located on an editor panel.
993 +
994 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
995 +
996 + 10. DBControlGrid: Removed memory leak when updating rows.
997 +
998 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
999 +
1000 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1001 +
1002 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1003 +   when target codepage is CP_NONE. This is a workaround for
1004 +   http://bugs.freepascal.org/view.php?id=30622.
1005 +
1006 + 2. DBLog option removed from TIBStatisticalService - not supported by server
1007 +   since Firebird 1.5.
1008 +
1009 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1010 +   similar.
1011 +
1012 + 4. IBCodePage: updated mapping between codepages and character id.
1013 +
1014 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1015 +   Firebird. Character sets with a char width of two are not UTF16.
1016 +
1017 + 6. Strings received from the database are now always transliterated into UTF8
1018 +   regardless of the database character set or connection character set. This
1019 +   is for compatibility with the LCL.
1020 +
1021 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1022 +
1023 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1024 +   read in an entire blob just to get the size of the blob. General performance
1025 +   improvement when opening datasets containing blobs.
1026 +
1027 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
1028 +
1029 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
1030 +   is now used.
1031 +
1032 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1033 +   determined.
1034 +
1035 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1036 +
1037 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1038 +   lazarus 1.6.0
1039 +
1040 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1041 +   compilation error.
1042 +
1043 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1044 +
1045 + 1. No character set specified for connection: when a text blob is retrieved, the
1046 +  character set is determined by looking up the native character set using then
1047 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
1048 +  set as the connection.
1049 +
1050 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1051 +   for Login Dialog returing a change to the database path.
1052 +
1053 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1054 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
1055 +   entered value to be saved on a project specific basis (design time only).
1056 +
1057 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1058 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
1059 +   Otherwise, it sets the column text to the selected ListField Value.
1060 +
1061 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1062 +   column width.
1063 +
1064 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1065 +   and a case insensitive search is requested.
1066 +
1067 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1068 +   or column ListSource.
1069 +
1070 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1071 +   unprepare) when closing and the text has not changed.
1072 +
1073 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1074 +   Less likely to cause a cursor re-use error on Windows.
1075 +
1076 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1077 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1078 +
1079 + 11. TIBTreeView: Guard against nil destination on record changed
1080 +
1081 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1082 +    string type with the code page set to reflect the returned field encoding after
1083 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1084 +    earlier versions.
1085 +
1086 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1087 +    will now result in transliteration to the code page specified for the Firebird driver
1088 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1089 +
1090 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1091 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1092 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1093 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1094 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1095 +    the GETACP is used to determine the Windows code page.
1096 +
1097 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1098 +    name used as the lc_ctype when the database was opened. Only valid while the
1099 +    Database is connected.
1100 +
1101 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1102 +    id that corresponds to the DefaultCharSetName.
1103 +
1104 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1105 +
1106 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1107 +   path is given and database attach fails due to access permission issues on the
1108 +   temp directory or security database, then the attach is retried with "localhost:"
1109 +   prefixing the databasename. This should avoid problems when the database has to
1110 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1111 +
1112 + 2. Windows: revised search order for Firebird DLL:
1113 +     i.   The Firebird Embedded Server in the application Directory.
1114 +     ii.  If the FIREBIRD environment variable is set then the directory this
1115 +          points to is searched for the FB Client DLL and then then underlying
1116 +          "bin" directory.
1117 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1118 +          is used to locate the Firebird installation directory and the underlying
1119 +          "bin" directory is searched for the FB Client DLL.
1120 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1121 +          are searched for the FB Client DLL.
1122 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1123 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1124 +
1125 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1126 +   See doc/readme.scriptengine and example applications.
1127 +
1128 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1129 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1130 +   See dpc/readme.localdatabase and example applications.
1131 +
1132 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1133 +   dynamic columns.
1134 +
1135 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1136 +   between incrementing/decrementing the lock count and signalling the event.
1137 +
1138 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1139 +
1140 + 1.3.2 was never formally released and only made available as beta copies.
1141 +
1142 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1143 +
1144 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1145 +
1146 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1147 +
1148 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1149 +   i.e. when it is a calculated field
1150 +
1151 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1152 +   This problem was due to a race condition between recalculating row heights and
1153 +   determining which row was selected by the mouse click. The row height calculation
1154 +   is now deferred by an extra trip round the message loop allowing the row to
1155 +   be always calculated on the current grid layout rather than risking it being
1156 +   calculated on the grid layout after the expanded row has been shrunk.
1157 +
1158 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1159 +   Windows.
1160 +
1161 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1162 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1163 +   to be determined at runtime. See doc/readme.charactersets.html.
1164 +
1165 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1166 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1167 +
1168 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1169 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1170 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1171 +
1172 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1173 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1174 +   implies no truncation.
1175 +
1176 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1177 +
1178 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1179 +   (avoids "Not in Edit Mode" error).
1180 +
1181 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1182 +
1183 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1184 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1185 +
1186 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1187 +
1188 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1189 +
1190 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1191 +
1192 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1193 +
1194 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1195 +
1196 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
1197 +
1198 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1199 +     problem with row size when exception is called.
1200 +
1201 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1202 +
1203 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1204 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
1205 +
1206 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1207 +     keyed in i.e. when autocomplete not performed
1208 +
1209 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1210 +     console mode applications with all LCL required functions (builtin dialogs and
1211 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1212 +     not included in your project, IBX should compile and link with a console mode program.
1213 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1214 +     console mode application or the IDE will automatically assume that your
1215 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1216 +
1217 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1218 +     to use the built in dialogs and cursor management. IBDialogs is
1219 +     included by default if "ibexpress" is in your project source's "uses" clause.
1220 +     This should be the case for all projects created through the IDE. This is why
1221 +     you do not want to add the ibexpress package to console mode applications. The
1222 +     ibexpressconsolemode package has been created to allow console mode programs
1223 +     to avoid adding LCL dependencies when using IBX, while still having the
1224 +     unit search paths set up correctly.
1225 +
1226 +     Existing users should check to ensure that the "ibexpress" unit is included in
1227 +     each project's source file (*.lpr).
1228 +
1229 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
1230 +     exists, you have to first open the package in the IDE and then close it. This
1231 +     adds it to the most recently accessed packages list. To make it permanently
1232 +     available, add the package name to lazarus' staticpackages.inc file.
1233 +
1234 +         Thanks to Julio Jiménez for suggesting support of console mode.
1235 +
1236 + 7.   SQL Parser can now accept quoted strings that include new lines
1237 +
1238 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1239 +     of text on start of edit. This is particularly useful when tabbing to a
1240 +     column and then inserting text.
1241 +
1242 + 9.   New Examples provided for IB Services and ISQLMonitor.
1243 +
1244 + 10. Fix error when writing to blob streams that recorded only the last buffer
1245 +    write in the blob stream. In most cases, this did not cause a problem as the
1246 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
1247 +    of a graphic type prefix was lost which caused a problem when the image could
1248 +        not be automatically recognised.
1249 +
1250 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1251 +    already open" errors due to random numbers used for the cursor name being identical.
1252 +
1253 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
1254 +    when opening the table and the Primary Key is the last or only column in the
1255 +    table. Thanks to Rick Hoover for the fix.
1256 +
1257 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1258 +    of "UTF-8", and update list of available database character sets. Existing
1259 +    users should check the current lc_ctype setting in their applications.

1261 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1262 +
1263 + 1.  Firebird Services: avoid List Index error when opening a service with an
1264 +    empty Params property.
1265 +
1266 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1267 +    Link now set up in Loaded method - avoids occasional failure to apply
1268 +    SQL markup on initial open.
1269 +
1270 + 3.  "Employees" example performance improvements when scrolling.
1271 +
1272 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1273 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1274 +    random image cached).
1275 +
1276 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
1277 +
1278 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1279 +    even when further rows exist.
1280 +
1281 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1282 +    always be derived from panel height and setting this property can cause confusion.
1283 +    Note for existing projects: to avoid a missing property error at run time,
1284 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
1285 +    in order to remove the property value from the lfm.
1286 +
1287 +
1288 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1289 +
1290 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1291 +    call Prepare before setting parameter values.
1292 +
1293 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1294 +
1295 + 3.  Code tidyup and more robust handling of dsql information result vector.
1296 +
1297 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
1298 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1299 +    and "AfterExecQuery". The first three are called after the same event is called
1300 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1301 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1302 +    enable monitoring of transaction status changes for a given transaction to be
1303 +    handled in a single place. For example, when a change to the dataset occurs
1304 +    an indicator can be set that shows the user that in order to save changes,
1305 +    the transaction should be committed.  Rather than doing this per dataset, this
1306 +    can now be done per transaction.
1307 +
1308 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1309 +    the dataset is scrolled. However, any changes to the current row are, by default,
1310 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1311 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
1312 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
1313 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1314 +    then IBX will attempt to post any unsaved changes before the dataset is closed
1315 +    (and after the BeforeClose event handler is called). The exception is when the
1316 +    dataset is being closed as a result of a transaction rollback. In this case,
1317 +    no action is taken and any unsaved  changes are discarded. This avoids both
1318 +    unnecessary overhead and the risk that a validation error may occur in the Post
1319 +    raising an exception and thereby preventing a rollback.
1320 +
1321 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1322 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1323 +    width. Display Widths are now corrected by dividing by the max byte width per character.
1324 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
1325 +    the byte width divided by 4. The byte width of each character set is determined
1326 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1327 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1328 +
1329 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1330 +
1331 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1332 +    control loses focus. Default Key press default interval reduced to 200ms.
1333 +
1334 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1335 +    when dataset rows are less than visible rows.
1336 +
1337 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1338 +    does not exist or DataSet is empty. More responsive on dataset open. New event
1339 +    OnRestorePosition. Column sort disabled if no header row.
1340 +
1341 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1342 +    while dataset state is dsInsert. Avoids posting errors.
1343 +
1344 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1345 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1346 +
1347 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1348 +
1349 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1350 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1351 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1352 +    always "posts" the current record regardless or whether or not it may be more appropriate
1353 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1354 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1355 +    as the first action of the "Post" method and allows the handler to convert the Post
1356 +    into a Cancel if that is the appropriate action on moving to a different row. This is
1357 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1358 +    raised here, but it may still be more appropriate to validate a post and signal
1359 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1360 +
1361 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
1362 +    separated list. Each library name on the list is tried in turn, in left to right
1363 +    order with the first found being used as the firebird library. By default, on Linux,
1364 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1365 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1366 +
1367 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1368 +    then it will still attempt to access the database via the Firebird Server and will
1369 +    require a username and password. If only the pathname is given, then the username
1370 +    and password should be omitted and the unix file permissions are used to grant
1371 +    access.
1372 +
1373 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1374 +
1375 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1376 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1377 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1378 +    corresponds to a row of the linked DataSource. Any data aware control on the
1379 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1380 +
1381 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1382 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1383 +   takes place during database access. This may be useful when there are performance issues with
1384 +   the change of cursor. Setting the property to false suppresses the change of cursor.
1385 +
1386 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1387 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1388 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1389 +   making all changes permanent immediately rather than when the transaction is explicitly
1390 +   committed.
1391 +
1392 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1393 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1394 +
1395 + IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1396 +
1397 + Development version only.
1398 +
1399 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1400 +
1401 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1402 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1403 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
1404 +   complexity.
1405 +
1406 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1407 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1408 +   These are:
1409 +
1410 +   - TIBLookupComboEditBox
1411 +   - TIBDynamicGrid
1412 +   - TIBTreeview
1413 +
1414 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1415 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1416 +   to revise the available list and restrict it to items that are prefixed by the
1417 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
1418 +   newly typed entry to be added to the list dataset and included in the available
1419 +   list items.
1420 +
1421 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
1422 +   - automatic resizing of selected columns to fill the available row length
1423 +   - automatic positioning and sizing of a "totals" control, typically at the
1424 +     column footer, on a per column basis.
1425 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
1426 +     A second click on the same header cell reversed the sort order.
1427 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1428 +     is automatically expanded and a panel superimposed on it. The panel can have any
1429 +     number of child controls, typically data aware controls with the same datasource
1430 +     as the grid allowing for editing of additional fields and more complex editors.
1431 +   - Reselection of the same row following resorting.
1432 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1433 +     Its properties are specified on a per column basis and allows for one or more
1434 +     columns to have their values selected from a list provided by a dataset.
1435 +     Autocomplete and autoinsert are also available. The existing picklist editor
1436 +     is unaffected by the extension.
1437 +
1438 +   TIBTreeView is a data aware TCustomTreeView.
1439 +
1440 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1441 +   zero scale will no longer return an error. An Int64 will be returned instead.
1442 +
1443 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
1444 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1445 +
1446 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1447 +   repeated multiple times.
1448 +
1449 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1450 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
1451 +   statements.
1452 +
1453 + 7. Insert, Modify and Delete property Editors now support Query Generation from
1454 +   Stored Procedures.
1455 +
1456 + 8. Three new examples illustrate the use of the new IB Controls
1457 +
1458 +
1459 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1460 +
1461 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1462 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1463 +   Gabor Boros for reporting this problem and for testing the improvements).
1464 +
1465 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1466 +   See readme.field+param.names in the doc folder.
1467 +
1468 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1469 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1470 +
1471 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1472 +
1473 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1474 +   actions.
1475 +
1476 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1477 +   thanks to Yuriy Kopnin for pointing this out).
1478 +
1479 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1480 +
1481 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1482 +   for both fields and parameter setting.
1483 +
1484 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1485 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1486 +
1487 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1488 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1489 +
1490 + 11. TIBTable now has a property editor for "MasterFields"
1491 +
1492 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1493 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1494 +
1495 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1496 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1497 +

1502 +
1503 + IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1504 +
1505 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1506 +   it is null. This allows for alternative user defined setting of the generator
1507 +
1508 +   Many thanks to Julio Jiménez for this fix
1509 +
1510 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1511 +   and suggests that the user may have forgotten to install it.
1512 +
1513 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1514 +
1515 + 1. Conditional compilation used to limit registration of TIntegerField to
1516 +   Lazarus versions less than 1.1
1517 +
1518 + 2. When a database connection is created, character set is now by default set
1519 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1520 +   1250 to 1254.
