1 + IBX Change Log  version (2.4-3 Build 12796) Mon, 06 Sep 2021 11:26:41 +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 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
8 +
9 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
10 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
11 +
12 + 2. TIBSQL: Batch Update/Insert support added.
13 +
14 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
15 +   is no longer automatically converted to upper case when it is syntactically a
16 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
17 +   as CREATE PROCEDURE "iCASE".
18 +
19 +   There could be a backwards compatibility issue when the StoredProcName was entered
20 +   manually at design time. That is not selected from the drop down list. If the
21 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
22 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
23 +   ensure that the value of the StoredProcName is all upper case, unless it was
24 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
25 +   quotes).
26 +
27 +   Note that when a stored procedure name was declared delimited in double quotes,
28 +   as in the first example above, the value of the StoredProcName property must not
29 +   include the delimiters (double quotes).
30 +
31 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
32 +   upgrade.conf was not found. This replaces silently ignoring the problem.
33 +
34 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
35 +   'Version.%.3d' and is used to generate the section header names (for a given
36 +   version no.) in the upgrade.conf file.
37 +
38 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
39 +
40 + 1. -c command line option added to fbsql example program. Used to set connection
41 +   character set.
42 +
43 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
44 +
45 + 1. Firebird 4 support added.
46 +
47 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
48 +   extended precision NUMERIC fields are supported.
49 +
50 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
51 +
52 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
53 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
54 +
55 + 5. IBExtract now supports FB4 enhancements:
56 +   - new data types as above
57 +   - Identity column extensions
58 +   - Default user role
59 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
60 +   - Internal Functions
61 +
62 + 6. IBExtract: new event: OnExtractLines.
63 +
64 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
65 +
66 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
67 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
68 +
69 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
70 +   format for rendering a time zone.
71 +
72 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
73 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
74 +
75 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
76 +    IIBGUIInterface and IIBTimerInf respectively.
77 +
78 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
79 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
80 +
81 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
82 +    truncated to its fixed character width rather than being right padded with
83 +    white space to the maximum data size.
84 +
85 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
86 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
87 +    also empty.
88 +
89 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
90 +
91 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
92 +    connect string. The database name is extracted from the connect string.
93 +
94 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
95 +
96 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
97 +
98 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
99 +    not being present as required.
100 +
101 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
102 +    version that can be customised to work with other database drivers.
103 +
104 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
105 +    unnecessary CR at end of line on Unix platforms.
106 +
107 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
108 +    seconds in order to reduce risk of message loss.
109 +
110 + 23. ISQLMonitor: read and write count statistics now available via:
111 +      property TIBSQLMonitor.ReadCount;
112 +      IIBSQLMonitorHook.GetWriteCount: integer;
113 +
114 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
115 +
116 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
117 +
118 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
119 +    number of UTF8 characters exceeds the string size then string is truncated
120 +    to the maximum string size. This is  usually a problem with fixed width columns
121 +    right padded with white space.
122 +
123 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
124 +    If SQLFiltered is set then when a dataset is opened, each line in the
125 +    SQLFilterParams property is assumed to be a SQL condition clause and
126 +    ANDed into the Where clause of the SQL Select statement provided as a
127 +    dataset property. Each such SQL condition thus acts as an additional filter
128 +    on the dataset.
129 +
130 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
131 +    side filters).
132 +
133 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
134 +   text matches complete entry.
135 +
136 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
137 +   dataset are active (avoids risk of access violation if master is inactive)
138 +
139 + 6. TIBEvents: Registered property can now be set at design time even if database not open
140 +
141 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
142 +   This should prevent "spillover" of events between sessions.
143 +
144 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
145 +   This should ensure that the internal buffer is set up correctly and avoids
146 +   a duplicate initial row.
147 +
148 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
149 +   That is, the DataSize should be the field size * character set width. The
150 +   value returned by DataSize is now the same as the Dataset buffer size reserved
151 +   for the field.
152 +
153 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
154 +
155 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
156 +    and vice-versa. This may result in an exception being raised (correctly) for
157 +    older programs when using dataset fields added to a form and the database has been
158 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
159 +    In such cases, the field needs to be deleted in the IDE fields editor and then
160 +    added back in.
161 +
162 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
163 +    false if query contains only white space and not just empty.
164 +
165 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
166 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
167 +    is cancelled.
168 +
169 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
170 +    called on a null field.
171 +
172 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
173 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
174 + set.
175 +
176 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
177 +    a cached update is applied and an exception is raised.
178 +
179 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
180 +
181 + 17. Console Mode Local Database support: backup/restore should now work correctly.
182 +
183 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
184 +    possible and an exception raised.
185 +
186 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
187 +    below this version no. and upgrade not possible.
188 +
189 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
190 +
191 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
192 +    not SQL Identifiers are now supported.
193 +
194 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
195 +    passed to the Firebird engine for execution.
196 +
197 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
198 +    is made to scroll back.
199 +
200 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
201 +
202 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
203 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
204 +
205 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
206 +   validated. If no match is found in the list of field names and the database has
207 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
208 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
209 +
210 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
211 +   with fpc 3.2.
212 +
213 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
214 +
215 +
216 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
217 +   and is used to override the default settings in the client side "firebird.conf" This
218 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
219 +   Each line of the string list should be a setting in the same format as "firebird.conf".
220 +   For example "WireCompression = true" in order to request wire compression on the client side.
221 +
222 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
223 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
224 +   also require a compatible setting in the server side "firebird.conf". For example
225 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
226 +   compression to be used.
227 +
228 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
229 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
230 +   ibx/examples/dbinfo for examples of how to display this information.
231 +
232 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
233 +   is a "convenience" property. If set the "WireCompression=true" is added to the
234 +   ConfigOverrides. If unchecked then this setting is removed.
235 +
236 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
237 +   not "INT64".
238 +
239 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
240 +   These are:
241 +    property TimestampFormat: string;
242 +    property DateFormat: string;
243 +    property TimeFormat: string;
244 +
245 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
246 +   DATETIME and TIME. The format strings use the standard FPC date/time format
247 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
248 +
249 +   If any of the above properties are set to an empty string, then the locale default
250 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
251 +   locale default is extended by appending '.zzz' to include milliseconds.
252 +
253 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
254 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
255 +
256 + 5. New published property for TIBCSVDataOut:
257 +     property QuoteStrings: boolean (default true)
258 +
259 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
260 +   used to delimit each and every string in the output.
261 +
262 + 6. New published properties for TIBCSVDataOut:
263 +    property FieldSeparator: string;
264 +    property HeaderSeparator: string;
265 +
266 +   Respectively, these provide the separator character(s) used to separate fields
267 +   in data and header rows. Both default to ','.
268 +
269 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
270 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
271 +    property OnFormatTextString;
272 +
273 +   This event handler can be used to process text strings before they are included
274 +   in the output e.g. to replace unprintable characters with alternative strings.
275 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
276 +
277 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
278 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
279 +   and without raising and exception if it does not.
280 +
281 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
282 +   consistency with SQL queries.
283 +
284 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
285 +    When true, SQL statement parameter names are parsed case sensitive. Note for
286 +    TIBDataSet only applies to Select query.
287 +
288 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
289 +    an IDE exception.
290 +
291 + 12. LocalDBSupport: initial database creation should now work correctly
292 +    when the schema source is an sql file.
293 +
294 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
295 +    when defined, this handler will be called by the internal TIBXScript during
296 +    initial database creation when the schema source is an sql file and may be used
297 +    to provide a visual indication of progress in console mode.
298 +
299 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
300 +    to true while a new local database is being created and its schema populated.
301 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
302 +    when the database is disconnected/connected during the create DB procedure.
303 +
304 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
305 +    are now always ignored and replaced by the user name and password provided as
306 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
307 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
308 +    completely ignored if this property is true.
309 +
310 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
311 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
312 +    ImageIndex and SelectImageIndex values on AddNode.
313 +
314 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
315 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
316 +    the same database connection.
317 +
318 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
319 +    if provided, this should be an conditional SQL expression suitable for
320 +    including in an SQL Select statement "where" clause. If non-empty and the
321 +    "Filtered" property is true then the SQL expression provided as the value of
322 +    the "Filter" property is "ANDed" with any existing condition statement
323 +    in the SQL statement's "Where" clause.
324 +
325 +    If the "Filter" property is set at run time, the "Filtered" property is true
326 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
327 +
328 +    The "Filter" condition may include IBX style parameters. In which case, their
329 +    value must be set by the dataset's "OnBeforeOpen" event handler.
330 +
331 +    This is a public property for TIBDataSet and TIBQuery query and intended for
332 +    use at run time.
333 +
334 +    Note: The property is a published property of TIBTable. The TIBTable functionality
335 +    is unaffected by this change.
336 +
337 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
338 +
339 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
340 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
341 +   mode apps.
342 +
343 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
344 +   statement. This avoids problems if "Execute Block" is used as the Query.
345 +
346 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
347 +   internal SQL tokeniser routines.
348 +
349 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
350 +   as a select statement, with or without CTEs.
351 +
352 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
353 +
354 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
355 +   internal SQL tokeniser routines.
356 +
357 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
358 +    being raised for valid set statements processed by a data formatter.
359 +
360 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
361 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
362 +   the path of the Firebird Library used by the database/services connection.
363 +
364 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
365 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
366 +   services connection.
367 +
368 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
369 +   or param name is not a valid SQL identifier.
370 +
371 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
372 +    view of whether the text box should be editable when no DataSource is specified.
373 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
374 +    ReadOnly is false, the text box is editable when no DataSource is specified.
375 +
376 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
377 +    the FBLIB environment variable. If you do not want to permit this then you
378 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
379 +    this setting.
380 +
381 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
382 +
383 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
384 +   Utf8EscapeControlChars
385 +
386 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
387 +
388 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
389 + all previous copies of the IBX source code tree before installing this release.
390 +
391 + The IBX packages used by most users have not changed, with one exception. The
392 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
393 + to use the IBServices unit in your applications, please add the iblegacyServices
394 + to the list of dependencies. To do this, open the Project Inspector and select
395 + Add->New Requirement and select "ibLegacyServices" from the list of available
396 + packages.
397 +
398 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
399 +   the IBServices unit providing what is intended to be a clearer and easier to
400 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
401 +   more information and the guide to "Firebird Service Management Using IBX".
402 +   As indicated above, the legacy services components are still available and
403 +   provided in a separate package. There is no need to update working applications
404 +   using the older versions except for an additional package dependency.
405 +
406 + 2. The IBX packages and source code tree have been re-organised in an attempt to
407 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
408 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
409 +   new set of IBX packages.
410 +
411 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
412 +   updated to use the new Services API components.
413 +
414 + 4. The iblocal package has been updated to use the new Services API components.
415 +
416 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
417 +   TIBXSecurityService. It had been wrongly classified in the previous version
418 +   as a per database configuration item. It is global to a server and hence
419 +   correctly positioned as part of the Security Package. In the DBAdmin example,
420 +   the setting has moved to the mappings page.
421 +
422 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
423 +   are ignored.
424 +
425 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
426 +   closed before the database is dropped. Before and After Disconnect event handlers
427 +   are also fired.
428 +
429 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
430 +   is started and not just the first time.
431 +
432 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
433 +   depenendency with comp type.
434 +
435 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
436 +
437 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
438 +    then this is recognised and not ignored.
439 +
440 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
441 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
442 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
443 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
444 +
445 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
446 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
447 +    counters for the select query. Note: stats accumulate after each fetch from
448 +    the database. To get total query cost after open, call the "Last" method
449 +    and then GetPerfStatistics.
450 +
451 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
452 +
453 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
454 +    in parenthesises.
455 +
456 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
457 +    SQL identifiers are always delimited by double quotes. If false, then they are
458 +    only delimited if the identifier is a reserved word, contains lower case or special
459 +    characters. Set this property to true to retain previous behaviour.
460 +
461 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
462 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
463 +
464 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
465 +       property MasterDetailDelay: integer {defaults to zero}
466 +
467 +    When non-zero and the dataset is a detail table referencing a master table
468 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
469 +    then a synchronisation delay is added (in milliseconds) between the master
470 +    row changing and the detail dataset being re-opened. If the master dataset
471 +    is scrolled before the delay expires then the delay is reset. This can be used
472 +    to avoid performance overheads when scrolling through a large master dataset.
473 +
474 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
475 +    chreads unit must be included in your project. TTimer is not used in order
476 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
477 +
478 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
479 +    with Extract Option eoDatabase.
480 +
481 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
482 +    When a deLayoutChanged event is reported on the ListSource dataset, the
483 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
484 +    relationship with the control's datasource (master).
485 +
486 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
487 +
488 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
489 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
490 +
491 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
492 +    DDL (Firebird 3 and later only).
493 +
494 + 22. TIBLookupComboBox Autocomplete Fixes:
495 +    i. Only appended text is now selected after autocomplete.
496 +    ii. Uppercase keys no longer ignored for autocomplete.
497 +    iii. Retain Prefix case is now honoured correctly.
498 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
499 +        before autocomplete performed. i.e. behaviour now the same as when
500 +        no DataSource assigned.
501 +
502 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
503 +    between SQL statements.
504 +
505 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
506 +    ObjectNames are converted to upper case before matching against metadata object
507 +    names, unless the objectname is delimited by double quotes, in which case, the
508 +    double quotes are removed and the remaining string is used (unmodified) to match
509 +    against the metadata object name.
510 +
511 +    If true then the ObjectName is used as is without modification and matched
512 +    against the metadata object name. No attempt is made to remove double quotes.
513 +
514 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
515 +    with eoTrigger, these extract types can be used to select only Database Triggers,
516 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
517 +
518 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
519 +    statement separate character is now reset to the default (';').
520 +
521 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
522 +
523 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
524 +    a commit or reconnect statement and instead activated only when next SQL statement
525 +    is executed.
526 +
527 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
528 +
529 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
530 +    converting statement to upper case.
531 +
532 + 31. TIBExtract: metadata comments now supported. New published property
533 +    IncludeMetaDataComments (default true). If true then metadata comments included
534 +    in extracted DDL. New Extract Object member eoComments. This may be used with
535 +    ExtractObject method to list all metadata comments.
536 +
537 + 32. TIBExtract: ListObjectNames method added.
538 +
539 + 33. Updated Database component editor to support additional connection string
540 +    types.
541 +
542 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
543 +
544 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
545 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
546 + RELEASE.
547 +
548 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
549 +
550 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
551 +
552 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
553 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
554 +   information). However, this is also a very useful mechanism for returning updated computed by
555 +   column values. Values returned as a result of executing an Insert or Update statement
556 +   replace existing values in the current row for each corresponding column.
557 +
558 +   Previously, if a dataset's select query included read only (computed by) fields then
559 +   an automatic row refresh was performed after an insert or update query had been processed,
560 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
561 +   that an automatic refresh is no longer performed if an insert or update query contains
562 +   a returning clause that updates one or more fields on the current row. A full row
563 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
564 +   field values and the select query contains read only fields. Use of Insert/update
565 +   returning should be significantly more efficient than executing a refresh query.
566 +
567 +   This behaviour change is intended to be backwards compatible and there should be no need to change
568 +   existing programs, other than to improve performance by using the new capability.
569 +
570 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
571 +   they are called when the dataset row is being deleted, there is no value in
572 +   updating the current record from the query result. Instead, a new event handler
573 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
574 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
575 +   by the query. The event handler can then interrogate the query results and
576 +   perform whatever action is necessary. For example to confirm, to the user,
577 +   the deletion of a row with the returned values.
578 +
579 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
580 +   any Computed By or Identity Columns. The IBTables example has been updated to
581 +   illustrate the computation of the employee Full Name on update.
582 +
583 + 5. TIBTable: The GeneratorField property is now published.
584 +
585 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
586 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
587 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
588 +   each Identity column after the insert is executed.
589 +
590 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
591 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
592 +   Insert..Returning clause.
593 +
594 + 8. TIBGenerator: small performance improvement by not preparing query each time
595 +   a new value is generated.
596 +
597 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
598 +
599 + 10. Property editors will now sync table name to a System Table when "Include System
600 +    Tables" is selected and the query is for a System Table.
601 +
602 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
603 +    values are no longer converted to milliseconds from TDateTime and then back again
604 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
605 +
606 + 12. Property Editors handling of Stored Procedures.
607 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
608 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
609 +      query).
610 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
611 +
612 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
613 +    can be used to select a package. If non-empty, the stored procedure name is
614 +    expected to be a stored procedure defined in the specified package and the
615 +    generated SQL will be as required for a stored procedure located in a package.
616 +
617 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
618 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
619 +    which a stored procedure can be selected. With no package name selected, non-package
620 +    stored procedures are listed.
621 +
622 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
623 +    for password on reconnect.
624 +
625 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
626 +    and character set name.
627 +
628 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
629 +    DB info lookups"
630 +
631 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
632 +
633 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
634 +
635 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
636 +    parameters. This stops an exception being raised when the field cannot be
637 +    located in the record buffer.
638 +
639 + 21. Property Editors now automatically include System Tables when opened and when the query table
640 +    is a System Table.
641 +
642 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
643 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
644 +
645 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
646 +    add the SPB item isc_spb_expected_db. This names a database using
647 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
648 +    database. examples/services re-written to illustrate use of "expected_db".
649 +
650 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
651 +    This avoids truncated backups when the server returns a timeout (busy) response.
652 +
653 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
654 +
655 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
656 +    databasenames. These are respectively expanded to the local system's temp directory
657 +    (including trailing delimiter) or to a prescribed data directory (including
658 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
659 +    in the user's home directory. The hidden directory name is either the string returned
660 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
661 +    Under Windows, the directory is the same as the Data Directory as decribed
662 +    above but instead prefixed by the User's application data path. These may be
663 +    used to improve application portability for Personal Databases.
664 +
665 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
666 +    this has not worked for a long time and is not useful either. FieldDefs should be
667 +    managed using the Fields Editor as with any other dataset. To access the fields
668 +    editor for a TIBTable component, double click on the component. The fields editor
669 +    is then displayed.
670 +
671 + 28. TIBDatabaseInfo: new properties/function
672 +     * DateDBCreated (returns date/time database created)
673 +     * TransactionCount (returns no. of active transactions)
674 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
675 +     * PagesFree (Firebird 3 or later)
676 +     * PagesUsed (Firebird 3 or later)
677 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
678 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
679 +
680 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
681 +
682 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
683 +
684 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
685 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
686 +
687 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
688 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
689 +    firing during backup and restore.
690 +
691 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
692 +    for verbose output using the new property "StatisticsRequested".
693 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
694 +
695 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
696 +
697 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
698 +    palette. This uses the online validation feature added in Firebird 2.5. The
699 +    services's properties enable inclusion/exclusion of tables and indexes using
700 +    regular expressions. See.
701 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
702 +
703 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
704 +    option on a database.
705 +
706 + 37. TIBCustomService: Assign method implemented to allow copying of service login
707 +    context between service API components. "Detach" method now only detaches
708 +    service when last reference to the service interface detaches. Tidy up of
709 +    code for SetActive and Attach methods including password hiding.
710 +
711 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
712 +    and used to determine the auth method and protocol used for the connection.
713 +
714 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
715 +    a Create Database Statement generated by IBX.
716 +
717 + 40. All IBServices now have an additional published property "PortNo". This may
718 +    be set to a non-standard port number when necessary. If zero then the default
719 +    port number is used.
720 +
721 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
722 +    and not just the mouse.
723 +
724 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
725 +
726 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
727 +    image index and selected image index for each node to be set from a database field.
728 +
729 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
730 +    then database schema includes grants to all users. If not present then the
731 +    only user grants included are those to User PUBLIC.
732 +
733 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
734 +    and child nodes in dataset.
735 +
736 +
737 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
738 +
739 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
740 +   changes.
741 +
742 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
743 +   Bug could result in truncated multi-byte character set values.
744 +
745 + 3. Changes consequential on moving fbintf character set utility functions from
746 +   IFirebirdAPI to IAttachment.
747 +
748 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
749 +
750 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
751 +   results in autocomplete ignoring prefix text.
752 +
753 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
754 +   entering a new name into the text box.
755 +
756 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
757 +   Firebird rather than recomputing it.
758 +
759 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
760 +   screen centre. Previously some were "poDesigned" which may be inappropriate
761 +   for multi monitor desktops.
762 +
763 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
764 +
765 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
766 +    a transaction and always reset the object.
767 +
768 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
769 +
770 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
771 +
772 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
773 +    to a gbak format archive.
774 +
775 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
776 +
777 + 16. IBLocaldb: Drop database if error creating an empty database.
778 +
779 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
780 +    unless selected node not in current dataset.
781 +
782 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
783 +    to TIBCustomService, and IBlocalDB code tidy up.
784 +
785 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
786 +    behaviour due to uninitialised variable.
787 +
788 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
789 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
790 +
791 + 21. IBSQL: When Database changed ensure that all resources are freed.
792 +
793 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
794 +
795 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
796 +    * Line Wrap on SQL Token boundaries (on user command)
797 +    * auto-complete table names in drop down list of table names
798 +    * Double click on tablename or field name adds to SQL text
799 +
800 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
801 +
802 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
803 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
804 +    workaround for a problem in fpc 3.0.4 win64).
805 +
806 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
807 +
808 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
809 +
810 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
811 +
812 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
813 +   include remote system name.
814 +
815 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
816 +   tables when data included in output.
817 +
818 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
819 +   and timing information to be written to stdout. This may be used to locate
820 +   performance bottlenecks.
821 +
822 + 4. SQLParser: only call "OnChanging" event handler when value is different.
823 +
824 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
825 +
826 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
827 +   that BindFields is called when the query is next activated. Avoids FieldName
828 +   not found error.
829 +
830 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
831 +   purpose and allows the programmer to define any action they want for Update, Insert
832 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
833 +   filtering of updates, or use of statements such as Grant or Revoke instead of
834 +   normal DML. See User Manual for more information.
835 +
836 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
837 +
838 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
839 +
840 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
841 +
842 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
843 +   hexadecimal notation.
844 +
845 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
846 +   using a simple XML format.
847 +
848 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
849 +   grants to these objects.
850 +
851 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
852 +   dependency problems restoring complex databases.
853 +
854 + 7. TIBXScript: This component has been restructured to allow for the processing of
855 +   embedded XML in INSERT statements and to support interactive sources in addition
856 +   to non-interactive data sources such as files.
857 +
858 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
859 +
860 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
861 +   SET SQL DIALECT
862 +   SET TERM
863 +   SET AUTODDL
864 +   SET BAIL
865 +   SET ECHO
866 +   SET COUNT
867 +   SET STATS
868 +   SET NAMES <character set>
869 +
870 + 10. IBVersion unit added to hold current IBX Version Number information.
871 +
872 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
873 +    and domain definitions.
874 +
875 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
876 +    fully supported.
877 +
878 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
879 +
880 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

882 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
883 +
884 + See also doc/IBX4LazarusGuide.pdf for important information on
885 + upgrading to IBX2.
886 +
887 + 1. Size property of TIBStringField is now the width in characters of the field
888 +   and not the byte length. This applies only to multi-byte character sets such
889 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
890 +   code is not recognised as a bug and hence this change to align the behaviour.
891 +   The TStringField change is expected in fpc 3.2.0.
892 +
893 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
894 +   true (default) then Size property value saved in the lfm is ignored. Size is
895 +   always set from the dynamic information read from the database. It is unclear
896 +   why anyone would want to override this and set Size to false.
897 +
898 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
899 +   block.
900 +
901 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
902 +   exist when an attempt is made to connect to it (run time only) then an attempt
903 +   is made to create the database.
904 +
905 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
906 +   has been successfully created as a result of a call to CreateDatabase or when
907 +   creating a database after it was found not to exist.
908 +
909 + 6.  DBControlGrid: a race condition could result in the wrong row image being
910 +    written to the cache. This has been avoided by a trip round the message
911 +    loop before rendering the row image.
912 +
913 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
914 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
915 +    known to risk corrupt rendering of row images when the control is first
916 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
917 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
918 +
919 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
920 +    a TDateEdit control located on an editor panel.
921 +
922 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
923 +
924 + 10. DBControlGrid: Removed memory leak when updating rows.
925 +
926 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
927 +
928 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
929 +
930 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
931 +   when target codepage is CP_NONE. This is a workaround for
932 +   http://bugs.freepascal.org/view.php?id=30622.
933 +
934 + 2. DBLog option removed from TIBStatisticalService - not supported by server
935 +   since Firebird 1.5.
936 +
937 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
938 +   similar.
939 +
940 + 4. IBCodePage: updated mapping between codepages and character id.
941 +
942 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
943 +   Firebird. Character sets with a char width of two are not UTF16.
944 +
945 + 6. Strings received from the database are now always transliterated into UTF8
946 +   regardless of the database character set or connection character set. This
947 +   is for compatibility with the LCL.
948 +
949 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
950 +
951 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
952 +   read in an entire blob just to get the size of the blob. General performance
953 +   improvement when opening datasets containing blobs.
954 +
955 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
956 +
957 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
958 +   is now used.
959 +
960 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
961 +   determined.
962 +
963 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
964 +
965 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
966 +   lazarus 1.6.0
967 +
968 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
969 +   compilation error.
970 +
971 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
972 +
973 + 1. No character set specified for connection: when a text blob is retrieved, the
974 +  character set is determined by looking up the native character set using then
975 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
976 +  set as the connection.
977 +
978 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
979 +   for Login Dialog returing a change to the database path.
980 +
981 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
982 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
983 +   entered value to be saved on a project specific basis (design time only).
984 +
985 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
986 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
987 +   Otherwise, it sets the column text to the selected ListField Value.
988 +
989 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
990 +   column width.
991 +
992 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
993 +   and a case insensitive search is requested.
994 +
995 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
996 +   or column ListSource.
997 +
998 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
999 +   unprepare) when closing and the text has not changed.
1000 +
1001 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1002 +   Less likely to cause a cursor re-use error on Windows.
1003 +
1004 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1005 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1006 +
1007 + 11. TIBTreeView: Guard against nil destination on record changed
1008 +
1009 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1010 +    string type with the code page set to reflect the returned field encoding after
1011 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1012 +    earlier versions.
1013 +
1014 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1015 +    will now result in transliteration to the code page specified for the Firebird driver
1016 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1017 +
1018 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1019 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1020 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1021 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1022 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1023 +    the GETACP is used to determine the Windows code page.
1024 +
1025 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1026 +    name used as the lc_ctype when the database was opened. Only valid while the
1027 +    Database is connected.
1028 +
1029 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1030 +    id that corresponds to the DefaultCharSetName.
1031 +
1032 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1033 +
1034 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1035 +   path is given and database attach fails due to access permission issues on the
1036 +   temp directory or security database, then the attach is retried with "localhost:"
1037 +   prefixing the databasename. This should avoid problems when the database has to
1038 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1039 +
1040 + 2. Windows: revised search order for Firebird DLL:
1041 +     i.   The Firebird Embedded Server in the application Directory.
1042 +     ii.  If the FIREBIRD environment variable is set then the directory this
1043 +          points to is searched for the FB Client DLL and then then underlying
1044 +          "bin" directory.
1045 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1046 +          is used to locate the Firebird installation directory and the underlying
1047 +          "bin" directory is searched for the FB Client DLL.
1048 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1049 +          are searched for the FB Client DLL.
1050 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1051 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1052 +
1053 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1054 +   See doc/readme.scriptengine and example applications.
1055 +
1056 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1057 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1058 +   See dpc/readme.localdatabase and example applications.
1059 +
1060 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1061 +   dynamic columns.
1062 +
1063 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1064 +   between incrementing/decrementing the lock count and signalling the event.
1065 +
1066   IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1067  
1068 + 1.3.2 was never formally released and only made available as beta copies.
1069 +
1070   1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1071  
1072   2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
# Line 21 | Line 1088 | IBX Change Log  version           (1.3-2
1088  
1089   7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1090     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1091 <   to be determined at runtime.
1091 >   to be determined at runtime. See doc/readme.charactersets.html.
1092  
1093   8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1094 <   TWideStringField. This field type is used with the character size reported by Firebird is two.
1094 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1095  
1096   9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1097     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1098 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
1098 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1099  
1100     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1101     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
