# Line 1 | Line 1
1 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
2 +
3 + 1. Add try-..except check when initially loading library in IDE. This should
4 + ensure that IDE continues to load even when a failure occurs in IBX load
5 + library.
6 +
7 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 +   hence will correctly detect end of the outer containing block when the block
9 +   contains a SELECT ... CASE ... END construct.
10 +
11 + 3. IBExtract: some further tidying up to remove extraneous white space.
12 +
13 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
14 +   errors when extra elements are added to DB.TFieldType.
15 +
16 + 5. IBUpdate: updated to reflect changes to ISQLParam.
17 +
18 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
19 +
20 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
21 +
22 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
23 +
24 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
25 +
26 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
27 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
28 +
29 + 2. TIBSQL: Batch Update/Insert support added.
30 +
31 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
32 +   is no longer automatically converted to upper case when it is syntactically a
33 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
34 +   as CREATE PROCEDURE "iCASE".
35 +
36 +   There could be a backwards compatibility issue when the StoredProcName was entered
37 +   manually at design time. That is not selected from the drop down list. If the
38 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
39 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
40 +   ensure that the value of the StoredProcName is all upper case, unless it was
41 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
42 +   quotes).
43 +
44 +   Note that when a stored procedure name was declared delimited in double quotes,
45 +   as in the first example above, the value of the StoredProcName property must not
46 +   include the delimiters (double quotes).
47 +
48 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
49 +   upgrade.conf was not found. This replaces silently ignoring the problem.
50 +
51 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
52 +   'Version.%.3d' and is used to generate the section header names (for a given
53 +   version no.) in the upgrade.conf file.
54 +
55 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
56 +
57 + 1. -c command line option added to fbsql example program. Used to set connection
58 +   character set.
59 +
60 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
61 +
62 + 1. Firebird 4 support added.
63 +
64 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
65 +   extended precision NUMERIC fields are supported.
66 +
67 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
68 +
69 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
70 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
71 +
72 + 5. IBExtract now supports FB4 enhancements:
73 +   - new data types as above
74 +   - Identity column extensions
75 +   - Default user role
76 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
77 +   - Internal Functions
78 +
79 + 6. IBExtract: new event: OnExtractLines.
80 +
81 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
82 +
83 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
84 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
85 +
86 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
87 +   format for rendering a time zone.
88 +
89 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
90 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
91 +
92 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
93 +    IIBGUIInterface and IIBTimerInf respectively.
94 +
95 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
96 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
97 +
98 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
99 +    truncated to its fixed character width rather than being right padded with
100 +    white space to the maximum data size.
101 +
102 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
103 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
104 +    also empty.
105 +
106 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
107 +
108 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
109 +    connect string. The database name is extracted from the connect string.
110 +
111 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
112 +
113 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
114 +
115 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
116 +    not being present as required.
117 +
118 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
119 +    version that can be customised to work with other database drivers.
120 +
121 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
122 +    unnecessary CR at end of line on Unix platforms.
123 +
124 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
125 +    seconds in order to reduce risk of message loss.
126 +
127 + 23. ISQLMonitor: read and write count statistics now available via:
128 +      property TIBSQLMonitor.ReadCount;
129 +      IIBSQLMonitorHook.GetWriteCount: integer;
130 +
131 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
132 +
133 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
134 +
135 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
136 +    number of UTF8 characters exceeds the string size then string is truncated
137 +    to the maximum string size. This is  usually a problem with fixed width columns
138 +    right padded with white space.
139 +
140 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
141 +    If SQLFiltered is set then when a dataset is opened, each line in the
142 +    SQLFilterParams property is assumed to be a SQL condition clause and
143 +    ANDed into the Where clause of the SQL Select statement provided as a
144 +    dataset property. Each such SQL condition thus acts as an additional filter
145 +    on the dataset.
146 +
147 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
148 +    side filters).
149 +
150 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
151 +   text matches complete entry.
152 +
153 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
154 +   dataset are active (avoids risk of access violation if master is inactive)
155 +
156 + 6. TIBEvents: Registered property can now be set at design time even if database not open
157 +
158 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
159 +   This should prevent "spillover" of events between sessions.
160 +
161 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
162 +   This should ensure that the internal buffer is set up correctly and avoids
163 +   a duplicate initial row.
164 +
165 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
166 +   That is, the DataSize should be the field size * character set width. The
167 +   value returned by DataSize is now the same as the Dataset buffer size reserved
168 +   for the field.
169 +
170 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
171 +
172 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
173 +    and vice-versa. This may result in an exception being raised (correctly) for
174 +    older programs when using dataset fields added to a form and the database has been
175 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
176 +    In such cases, the field needs to be deleted in the IDE fields editor and then
177 +    added back in.
178 +
179 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
180 +    false if query contains only white space and not just empty.
181 +
182 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
183 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
184 +    is cancelled.
185 +
186 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
187 +    called on a null field.
188 +
189 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
190 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
191 + set.
192 +
193 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
194 +    a cached update is applied and an exception is raised.
195 +
196 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
197 +
198 + 17. Console Mode Local Database support: backup/restore should now work correctly.
199 +
200 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
201 +    possible and an exception raised.
202 +
203 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
204 +    below this version no. and upgrade not possible.
205 +
206 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
207 +
208 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
209 +    not SQL Identifiers are now supported.
210 +
211 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
212 +    passed to the Firebird engine for execution.
213 +
214 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
215 +    is made to scroll back.
216 +
217 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
218 +
219 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
220 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
221 +
222 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
223 +   validated. If no match is found in the list of field names and the database has
224 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
225 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
226 +
227 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
228 +   with fpc 3.2.
229 +
230 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
231 +
232 +
233 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
234 +   and is used to override the default settings in the client side "firebird.conf" This
235 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
236 +   Each line of the string list should be a setting in the same format as "firebird.conf".
237 +   For example "WireCompression = true" in order to request wire compression on the client side.
238 +
239 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
240 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
241 +   also require a compatible setting in the server side "firebird.conf". For example
242 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
243 +   compression to be used.
244 +
245 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
246 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
247 +   ibx/examples/dbinfo for examples of how to display this information.
248 +
249 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
250 +   is a "convenience" property. If set the "WireCompression=true" is added to the
251 +   ConfigOverrides. If unchecked then this setting is removed.
252 +
253 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
254 +   not "INT64".
255 +
256 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
257 +   These are:
258 +    property TimestampFormat: string;
259 +    property DateFormat: string;
260 +    property TimeFormat: string;
261 +
262 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
263 +   DATETIME and TIME. The format strings use the standard FPC date/time format
264 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
265 +
266 +   If any of the above properties are set to an empty string, then the locale default
267 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
268 +   locale default is extended by appending '.zzz' to include milliseconds.
269 +
270 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
271 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
272 +
273 + 5. New published property for TIBCSVDataOut:
274 +     property QuoteStrings: boolean (default true)
275 +
276 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
277 +   used to delimit each and every string in the output.
278 +
279 + 6. New published properties for TIBCSVDataOut:
280 +    property FieldSeparator: string;
281 +    property HeaderSeparator: string;
282 +
283 +   Respectively, these provide the separator character(s) used to separate fields
284 +   in data and header rows. Both default to ','.
285 +
286 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
287 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
288 +    property OnFormatTextString;
289 +
290 +   This event handler can be used to process text strings before they are included
291 +   in the output e.g. to replace unprintable characters with alternative strings.
292 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
293 +
294 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
295 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
296 +   and without raising and exception if it does not.
297 +
298 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
299 +   consistency with SQL queries.
300 +
301 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
302 +    When true, SQL statement parameter names are parsed case sensitive. Note for
303 +    TIBDataSet only applies to Select query.
304 +
305 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
306 +    an IDE exception.
307 +
308 + 12. LocalDBSupport: initial database creation should now work correctly
309 +    when the schema source is an sql file.
310 +
311 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
312 +    when defined, this handler will be called by the internal TIBXScript during
313 +    initial database creation when the schema source is an sql file and may be used
314 +    to provide a visual indication of progress in console mode.
315 +
316 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
317 +    to true while a new local database is being created and its schema populated.
318 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
319 +    when the database is disconnected/connected during the create DB procedure.
320 +
321 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
322 +    are now always ignored and replaced by the user name and password provided as
323 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
324 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
325 +    completely ignored if this property is true.
326 +
327 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
328 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
329 +    ImageIndex and SelectImageIndex values on AddNode.
330 +
331 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
332 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
333 +    the same database connection.
334 +
335 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
336 +    if provided, this should be an conditional SQL expression suitable for
337 +    including in an SQL Select statement "where" clause. If non-empty and the
338 +    "Filtered" property is true then the SQL expression provided as the value of
339 +    the "Filter" property is "ANDed" with any existing condition statement
340 +    in the SQL statement's "Where" clause.
341 +
342 +    If the "Filter" property is set at run time, the "Filtered" property is true
343 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
344 +
345 +    The "Filter" condition may include IBX style parameters. In which case, their
346 +    value must be set by the dataset's "OnBeforeOpen" event handler.
347 +
348 +    This is a public property for TIBDataSet and TIBQuery query and intended for
349 +    use at run time.
350 +
351 +    Note: The property is a published property of TIBTable. The TIBTable functionality
352 +    is unaffected by this change.
353 +
354 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
355 +
356 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
357 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
358 +   mode apps.
359 +
360 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
361 +   statement. This avoids problems if "Execute Block" is used as the Query.
362 +
363 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
364 +   internal SQL tokeniser routines.
365 +
366 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
367 +   as a select statement, with or without CTEs.
368 +
369 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
370 +
371 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
372 +   internal SQL tokeniser routines.
373 +
374 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
375 +    being raised for valid set statements processed by a data formatter.
376 +
377 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
378 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
379 +   the path of the Firebird Library used by the database/services connection.
380 +
381 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
382 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
383 +   services connection.
384 +
385 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
386 +   or param name is not a valid SQL identifier.
387 +
388 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
389 +    view of whether the text box should be editable when no DataSource is specified.
390 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
391 +    ReadOnly is false, the text box is editable when no DataSource is specified.
392 +
393 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
394 +    the FBLIB environment variable. If you do not want to permit this then you
395 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
396 +    this setting.
397 +
398 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
399 +
400 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
401 +   Utf8EscapeControlChars
402 +
403 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
404 +
405 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
406 + all previous copies of the IBX source code tree before installing this release.
407 +
408 + The IBX packages used by most users have not changed, with one exception. The
409 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
410 + to use the IBServices unit in your applications, please add the iblegacyServices
411 + to the list of dependencies. To do this, open the Project Inspector and select
412 + Add->New Requirement and select "ibLegacyServices" from the list of available
413 + packages.
414 +
415 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
416 +   the IBServices unit providing what is intended to be a clearer and easier to
417 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
418 +   more information and the guide to "Firebird Service Management Using IBX".
419 +   As indicated above, the legacy services components are still available and
420 +   provided in a separate package. There is no need to update working applications
421 +   using the older versions except for an additional package dependency.
422 +
423 + 2. The IBX packages and source code tree have been re-organised in an attempt to
424 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
425 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
426 +   new set of IBX packages.
427 +
428 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
429 +   updated to use the new Services API components.
430 +
431 + 4. The iblocal package has been updated to use the new Services API components.
432 +
433 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
434 +   TIBXSecurityService. It had been wrongly classified in the previous version
435 +   as a per database configuration item. It is global to a server and hence
436 +   correctly positioned as part of the Security Package. In the DBAdmin example,
437 +   the setting has moved to the mappings page.
438 +
439 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
440 +   are ignored.
441 +
442 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
443 +   closed before the database is dropped. Before and After Disconnect event handlers
444 +   are also fired.
445 +
446 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
447 +   is started and not just the first time.
448 +
449 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
450 +   depenendency with comp type.
451 +
452 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
453 +
454 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
455 +    then this is recognised and not ignored.
456 +
457 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
458 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
459 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
460 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
461 +
462 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
463 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
464 +    counters for the select query. Note: stats accumulate after each fetch from
465 +    the database. To get total query cost after open, call the "Last" method
466 +    and then GetPerfStatistics.
467 +
468 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
469 +
470 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
471 +    in parenthesises.
472 +
473 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
474 +    SQL identifiers are always delimited by double quotes. If false, then they are
475 +    only delimited if the identifier is a reserved word, contains lower case or special
476 +    characters. Set this property to true to retain previous behaviour.
477 +
478 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
479 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
480 +
481 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
482 +       property MasterDetailDelay: integer {defaults to zero}
483 +
484 +    When non-zero and the dataset is a detail table referencing a master table
485 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
486 +    then a synchronisation delay is added (in milliseconds) between the master
487 +    row changing and the detail dataset being re-opened. If the master dataset
488 +    is scrolled before the delay expires then the delay is reset. This can be used
489 +    to avoid performance overheads when scrolling through a large master dataset.
490 +
491 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
492 +    chreads unit must be included in your project. TTimer is not used in order
493 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
494 +
495 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
496 +    with Extract Option eoDatabase.
497 +
498 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
499 +    When a deLayoutChanged event is reported on the ListSource dataset, the
500 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
501 +    relationship with the control's datasource (master).
502 +
503 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
504 +
505 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
506 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
507 +
508 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
509 +    DDL (Firebird 3 and later only).
510 +
511 + 22. TIBLookupComboBox Autocomplete Fixes:
512 +    i. Only appended text is now selected after autocomplete.
513 +    ii. Uppercase keys no longer ignored for autocomplete.
514 +    iii. Retain Prefix case is now honoured correctly.
515 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
516 +        before autocomplete performed. i.e. behaviour now the same as when
517 +        no DataSource assigned.
518 +
519 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
520 +    between SQL statements.
521 +
522 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
523 +    ObjectNames are converted to upper case before matching against metadata object
524 +    names, unless the objectname is delimited by double quotes, in which case, the
525 +    double quotes are removed and the remaining string is used (unmodified) to match
526 +    against the metadata object name.
527 +
528 +    If true then the ObjectName is used as is without modification and matched
529 +    against the metadata object name. No attempt is made to remove double quotes.
530 +
531 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
532 +    with eoTrigger, these extract types can be used to select only Database Triggers,
533 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
534 +
535 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
536 +    statement separate character is now reset to the default (';').
537 +
538 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
539 +
540 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
541 +    a commit or reconnect statement and instead activated only when next SQL statement
542 +    is executed.
543 +
544 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
545 +
546 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
547 +    converting statement to upper case.
548 +
549 + 31. TIBExtract: metadata comments now supported. New published property
550 +    IncludeMetaDataComments (default true). If true then metadata comments included
551 +    in extracted DDL. New Extract Object member eoComments. This may be used with
552 +    ExtractObject method to list all metadata comments.
553 +
554 + 32. TIBExtract: ListObjectNames method added.
555 +
556 + 33. Updated Database component editor to support additional connection string
557 +    types.
558 +
559 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
560 +
561 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
562 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
563 + RELEASE.
564 +
565 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
566 +
567 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
568 +
569 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
570 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
571 +   information). However, this is also a very useful mechanism for returning updated computed by
572 +   column values. Values returned as a result of executing an Insert or Update statement
573 +   replace existing values in the current row for each corresponding column.
574 +
575 +   Previously, if a dataset's select query included read only (computed by) fields then
576 +   an automatic row refresh was performed after an insert or update query had been processed,
577 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
578 +   that an automatic refresh is no longer performed if an insert or update query contains
579 +   a returning clause that updates one or more fields on the current row. A full row
580 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
581 +   field values and the select query contains read only fields. Use of Insert/update
582 +   returning should be significantly more efficient than executing a refresh query.
583 +
584 +   This behaviour change is intended to be backwards compatible and there should be no need to change
585 +   existing programs, other than to improve performance by using the new capability.
586 +
587 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
588 +   they are called when the dataset row is being deleted, there is no value in
589 +   updating the current record from the query result. Instead, a new event handler
590 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
591 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
592 +   by the query. The event handler can then interrogate the query results and
593 +   perform whatever action is necessary. For example to confirm, to the user,
594 +   the deletion of a row with the returned values.
595 +
596 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
597 +   any Computed By or Identity Columns. The IBTables example has been updated to
598 +   illustrate the computation of the employee Full Name on update.
599 +
600 + 5. TIBTable: The GeneratorField property is now published.
601 +
602 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
603 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
604 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
605 +   each Identity column after the insert is executed.
606 +
607 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
608 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
609 +   Insert..Returning clause.
610 +
611 + 8. TIBGenerator: small performance improvement by not preparing query each time
612 +   a new value is generated.
613 +
614 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
615 +
616 + 10. Property editors will now sync table name to a System Table when "Include System
617 +    Tables" is selected and the query is for a System Table.
618 +
619 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
620 +    values are no longer converted to milliseconds from TDateTime and then back again
621 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
622 +
623 + 12. Property Editors handling of Stored Procedures.
624 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
625 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
626 +      query).
627 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
628 +
629 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
630 +    can be used to select a package. If non-empty, the stored procedure name is
631 +    expected to be a stored procedure defined in the specified package and the
632 +    generated SQL will be as required for a stored procedure located in a package.
633 +
634 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
635 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
636 +    which a stored procedure can be selected. With no package name selected, non-package
637 +    stored procedures are listed.
638 +
639 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
640 +    for password on reconnect.
641 +
642 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
643 +    and character set name.
644 +
645 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
646 +    DB info lookups"
647 +
648 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
649 +
650 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
651 +
652 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
653 +    parameters. This stops an exception being raised when the field cannot be
654 +    located in the record buffer.
655 +
656 + 21. Property Editors now automatically include System Tables when opened and when the query table
657 +    is a System Table.
658 +
659 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
660 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
661 +
662 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
663 +    add the SPB item isc_spb_expected_db. This names a database using
664 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
665 +    database. examples/services re-written to illustrate use of "expected_db".
666 +
667 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
668 +    This avoids truncated backups when the server returns a timeout (busy) response.
669 +
670 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
671 +
672 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
673 +    databasenames. These are respectively expanded to the local system's temp directory
674 +    (including trailing delimiter) or to a prescribed data directory (including
675 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
676 +    in the user's home directory. The hidden directory name is either the string returned
677 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
678 +    Under Windows, the directory is the same as the Data Directory as decribed
679 +    above but instead prefixed by the User's application data path. These may be
680 +    used to improve application portability for Personal Databases.
681 +
682 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
683 +    this has not worked for a long time and is not useful either. FieldDefs should be
684 +    managed using the Fields Editor as with any other dataset. To access the fields
685 +    editor for a TIBTable component, double click on the component. The fields editor
686 +    is then displayed.
687 +
688 + 28. TIBDatabaseInfo: new properties/function
689 +     * DateDBCreated (returns date/time database created)
690 +     * TransactionCount (returns no. of active transactions)
691 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
692 +     * PagesFree (Firebird 3 or later)
693 +     * PagesUsed (Firebird 3 or later)
694 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
695 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
696 +
697 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
698 +
699 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
700 +
701 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
702 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
703 +
704 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
705 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
706 +    firing during backup and restore.
707 +
708 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
709 +    for verbose output using the new property "StatisticsRequested".
710 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
711 +
712 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
713 +
714 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
715 +    palette. This uses the online validation feature added in Firebird 2.5. The
716 +    services's properties enable inclusion/exclusion of tables and indexes using
717 +    regular expressions. See.
718 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
719 +
720 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
721 +    option on a database.
722 +
723 + 37. TIBCustomService: Assign method implemented to allow copying of service login
724 +    context between service API components. "Detach" method now only detaches
725 +    service when last reference to the service interface detaches. Tidy up of
726 +    code for SetActive and Attach methods including password hiding.
727 +
728 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
729 +    and used to determine the auth method and protocol used for the connection.
730 +
731 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
732 +    a Create Database Statement generated by IBX.
733 +
734 + 40. All IBServices now have an additional published property "PortNo". This may
735 +    be set to a non-standard port number when necessary. If zero then the default
736 +    port number is used.
737 +
738 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
739 +    and not just the mouse.
740 +
741 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
742 +
743 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
744 +    image index and selected image index for each node to be set from a database field.
745 +
746 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
747 +    then database schema includes grants to all users. If not present then the
748 +    only user grants included are those to User PUBLIC.
749 +
750 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
751 +    and child nodes in dataset.
752 +
753 +
754 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
755 +
756 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
757 +   changes.
758 +
759 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
760 +   Bug could result in truncated multi-byte character set values.
761 +
762 + 3. Changes consequential on moving fbintf character set utility functions from
763 +   IFirebirdAPI to IAttachment.
764 +
765 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
766 +
767 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
768 +   results in autocomplete ignoring prefix text.
769 +
770 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
771 +   entering a new name into the text box.
772 +
773 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
774 +   Firebird rather than recomputing it.
775 +
776 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
777 +   screen centre. Previously some were "poDesigned" which may be inappropriate
778 +   for multi monitor desktops.
779 +
780 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
781 +
782 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
783 +    a transaction and always reset the object.
784 +
785 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
786 +
787 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
788 +
789 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
790 +    to a gbak format archive.
791 +
792 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
793 +
794 + 16. IBLocaldb: Drop database if error creating an empty database.
795 +
796 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
797 +    unless selected node not in current dataset.
798 +
799 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
800 +    to TIBCustomService, and IBlocalDB code tidy up.
801 +
802 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
803 +    behaviour due to uninitialised variable.
804 +
805 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
806 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
807 +
808 + 21. IBSQL: When Database changed ensure that all resources are freed.
809 +
810 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
811 +
812 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
813 +    * Line Wrap on SQL Token boundaries (on user command)
814 +    * auto-complete table names in drop down list of table names
815 +    * Double click on tablename or field name adds to SQL text
816 +
817 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
818 +
819 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
820 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
821 +    workaround for a problem in fpc 3.0.4 win64).
822 +
823 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
824 +
825 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
826 +
827 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
828 +
829 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
830 +   include remote system name.
831 +
832 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
833 +   tables when data included in output.
834 +
835 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
836 +   and timing information to be written to stdout. This may be used to locate
837 +   performance bottlenecks.
838 +
839 + 4. SQLParser: only call "OnChanging" event handler when value is different.
840 +
841 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
842 +
843 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
844 +   that BindFields is called when the query is next activated. Avoids FieldName
845 +   not found error.
846 +
847 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
848 +   purpose and allows the programmer to define any action they want for Update, Insert
849 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
850 +   filtering of updates, or use of statements such as Grant or Revoke instead of

853 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
854 +
855 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
856 +
857 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
858 +
859 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
860 +   hexadecimal notation.
861 +
862 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
863 +   using a simple XML format.
864 +
865 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
866 +   grants to these objects.
867 +
868 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
869 +   dependency problems restoring complex databases.
870 +
871 + 7. TIBXScript: This component has been restructured to allow for the processing of
872 +   embedded XML in INSERT statements and to support interactive sources in addition
873 +   to non-interactive data sources such as files.
874 +
875 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
876 +
877 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
878 +   SET SQL DIALECT
879 +   SET TERM
880 +   SET AUTODDL
881 +   SET BAIL
882 +   SET ECHO
883 +   SET COUNT
884 +   SET STATS
885 +   SET NAMES <character set>
886 +
887 + 10. IBVersion unit added to hold current IBX Version Number information.
888 +
889 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
890 +    and domain definitions.
891 +
892 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
893 +    fully supported.
894 +
895 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
896 +
897 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
898 +
899 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
900 +
901 + See also doc/IBX4LazarusGuide.pdf for important information on
902 + upgrading to IBX2.
903 +
904 + 1. Size property of TIBStringField is now the width in characters of the field
905 +   and not the byte length. This applies only to multi-byte character sets such
906 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
907 +   code is not recognised as a bug and hence this change to align the behaviour.
908 +   The TStringField change is expected in fpc 3.2.0.
909 +
910 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
911 +   true (default) then Size property value saved in the lfm is ignored. Size is
912 +   always set from the dynamic information read from the database. It is unclear
913 +   why anyone would want to override this and set Size to false.
914 +
915 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
916 +   block.
917 +
918 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
919 +   exist when an attempt is made to connect to it (run time only) then an attempt
920 +   is made to create the database.
921 +
922 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
923 +   has been successfully created as a result of a call to CreateDatabase or when
924 +   creating a database after it was found not to exist.
925 +
926 + 6.  DBControlGrid: a race condition could result in the wrong row image being
927 +    written to the cache. This has been avoided by a trip round the message
928 +    loop before rendering the row image.
929 +
930 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
931 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
932 +    known to risk corrupt rendering of row images when the control is first
933 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
934 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
935 +
936 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
937 +    a TDateEdit control located on an editor panel.
938 +
939 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
940 +
941 + 10. DBControlGrid: Removed memory leak when updating rows.
942 +
943 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
944 +
945 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
946 +
947 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
948 +   when target codepage is CP_NONE. This is a workaround for
949 +   http://bugs.freepascal.org/view.php?id=30622.
950 +
951 + 2. DBLog option removed from TIBStatisticalService - not supported by server
952 +   since Firebird 1.5.
953 +
954 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
955 +   similar.
956 +
957 + 4. IBCodePage: updated mapping between codepages and character id.
958 +
959 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
960 +   Firebird. Character sets with a char width of two are not UTF16.
961 +
962 + 6. Strings received from the database are now always transliterated into UTF8
963 +   regardless of the database character set or connection character set. This
964 +   is for compatibility with the LCL.
965 +
966 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
967 +
968 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
969 +   read in an entire blob just to get the size of the blob. General performance
970 +   improvement when opening datasets containing blobs.
971 +
972 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
973 +
974 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
975 +   is now used.
976 +
977 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
978 +   determined.
979 +
980 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
981 +
982 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
983 +   lazarus 1.6.0
984 +
985 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
986 +   compilation error.
987 +
988 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
989 +
990 + 1. No character set specified for connection: when a text blob is retrieved, the
991 +  character set is determined by looking up the native character set using then
992 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
993 +  set as the connection.
994 +
995 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
996 +   for Login Dialog returing a change to the database path.
997 +
998 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
999 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
1000 +   entered value to be saved on a project specific basis (design time only).
1001 +
1002 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1003 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
1004 +   Otherwise, it sets the column text to the selected ListField Value.
1005 +
1006 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1007 +   column width.
1008 +
1009 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1010 +   and a case insensitive search is requested.
1011 +
1012 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1013 +   or column ListSource.
1014 +
1015 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1016 +   unprepare) when closing and the text has not changed.
1017 +
1018 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1019 +   Less likely to cause a cursor re-use error on Windows.
1020 +
1021 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1022 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1023 +
1024 + 11. TIBTreeView: Guard against nil destination on record changed
1025 +
1026 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1027 +    string type with the code page set to reflect the returned field encoding after
1028 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1029 +    earlier versions.
1030 +
1031 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1032 +    will now result in transliteration to the code page specified for the Firebird driver
1033 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1034 +
1035 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1036 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1037 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1038 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1039 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1040 +    the GETACP is used to determine the Windows code page.
1041 +
1042 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1043 +    name used as the lc_ctype when the database was opened. Only valid while the
1044 +    Database is connected.
1045 +
1046 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1047 +    id that corresponds to the DefaultCharSetName.
1048 +
1049 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1050 +
1051 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1052 +   path is given and database attach fails due to access permission issues on the
1053 +   temp directory or security database, then the attach is retried with "localhost:"
1054 +   prefixing the databasename. This should avoid problems when the database has to
1055 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1056 +
1057 + 2. Windows: revised search order for Firebird DLL:
1058 +     i.   The Firebird Embedded Server in the application Directory.
1059 +     ii.  If the FIREBIRD environment variable is set then the directory this
1060 +          points to is searched for the FB Client DLL and then then underlying
1061 +          "bin" directory.
1062 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1063 +          is used to locate the Firebird installation directory and the underlying
1064 +          "bin" directory is searched for the FB Client DLL.
1065 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1066 +          are searched for the FB Client DLL.
1067 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1068 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1069 +
1070 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1071 +   See doc/readme.scriptengine and example applications.
1072 +
1073 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1074 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1075 +   See dpc/readme.localdatabase and example applications.
1076 +
1077 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1078 +   dynamic columns.
1079 +
1080 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1081 +   between incrementing/decrementing the lock count and signalling the event.
1082 +
1083 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1084 +
1085 + 1.3.2 was never formally released and only made available as beta copies.
1086 +
1087 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1088 +
1089 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1090 +
1091 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1092 +
1093 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1094 +   i.e. when it is a calculated field
1095 +
1096 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1097 +   This problem was due to a race condition between recalculating row heights and
1098 +   determining which row was selected by the mouse click. The row height calculation
1099 +   is now deferred by an extra trip round the message loop allowing the row to
1100 +   be always calculated on the current grid layout rather than risking it being
1101 +   calculated on the grid layout after the expanded row has been shrunk.
1102 +
1103 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1104 +   Windows.
1105 +
1106 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1107 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1108 +   to be determined at runtime. See doc/readme.charactersets.html.
1109 +
1110 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1111 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1112 +
1113 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1114 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1115 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1116 +
1117 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1118 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1119 +   implies no truncation.
1120 +
1121 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1122 +
1123 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1124 +   (avoids "Not in Edit Mode" error).
1125 +
1126 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1127 +
1128 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1129 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1130 +
1131 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1132 +
1133 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1134 +
1135 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1136 +
1137 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1138 +
