# Line 1 | Line 1
1 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
2 +
3 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
4 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
5 +
6 + 2. TIBSQL: Batch Update/Insert support added.
7 +
8 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
9 +   is no longer automatically converted to upper case when it is syntactically a
10 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
11 +   as CREATE PROCEDURE "iCASE".
12 +
13 +   There could be a backwards compatibility issue when the StoredProcName was entered
14 +   manually at design time. That is not selected from the drop down list. If the
15 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
16 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
17 +   ensure that the value of the StoredProcName is all upper case, unless it was
18 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
19 +   quotes).
20 +
21 +   Note that when a stored procedure name was declared delimited in double quotes,
22 +   as in the first example above, the value of the StoredProcName property must not
23 +   include the delimiters (double quotes).
24 +
25 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
26 +   upgrade.conf was not found. This replaces silently ignoring the problem.
27 +
28 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
29 +   'Version.%.3d' and is used to generate the section header names (for a given
30 +   version no.) in the upgrade.conf file.
31 +
32 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
33 +
34 + 1. -c command line option added to fbsql example program. Used to set connection
35 +   character set.
36 +
37 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
38 +
39 + 1. Firebird 4 support added.
40 +
41 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
42 +   extended precision NUMERIC fields are supported.
43 +
44 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
45 +
46 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
47 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
48 +
49 + 5. IBExtract now supports FB4 enhancements:
50 +   - new data types as above
51 +   - Identity column extensions
52 +   - Default user role
53 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
54 +   - Internal Functions
55 +
56 + 6. IBExtract: new event: OnExtractLines.
57 +
58 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
59 +
60 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
61 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
62 +
63 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
64 +   format for rendering a time zone.
65 +
66 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
67 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
68 +
69 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
70 +    IIBGUIInterface and IIBTimerInf respectively.
71 +
72 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
73 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
74 +
75 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
76 +    truncated to its fixed character width rather than being right padded with
77 +    white space to the maximum data size.
78 +
79 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
80 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
81 +    also empty.
82 +
83 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
84 +
85 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
86 +    connect string. The database name is extracted from the connect string.
87 +
88 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
89 +
90 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
91 +
92 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
93 +    not being present as required.
94 +
95 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
96 +    version that can be customised to work with other database drivers.
97 +
98 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
99 +    unnecessary CR at end of line on Unix platforms.
100 +
101 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
102 +    seconds in order to reduce risk of message loss.
103 +
104 + 23. ISQLMonitor: read and write count statistics now available via:
105 +      property TIBSQLMonitor.ReadCount;
106 +      IIBSQLMonitorHook.GetWriteCount: integer;
107 +
108 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
109 +
110 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
111 +
112 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
113 +    number of UTF8 characters exceeds the string size then string is truncated
114 +    to the maximum string size. This is  usually a problem with fixed width columns
115 +    right padded with white space.
116 +
117 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
118 +    If SQLFiltered is set then when a dataset is opened, each line in the
119 +    SQLFilterParams property is assumed to be a SQL condition clause and
120 +    ANDed into the Where clause of the SQL Select statement provided as a
121 +    dataset property. Each such SQL condition thus acts as an additional filter
122 +    on the dataset.
123 +
124 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
125 +    side filters).
126 +
127 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
128 +   text matches complete entry.
129 +
130 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
131 +   dataset are active (avoids risk of access violation if master is inactive)
132 +
133 + 6. TIBEvents: Registered property can now be set at design time even if database not open
134 +
135 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
136 +   This should prevent "spillover" of events between sessions.
137 +
138 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
139 +   This should ensure that the internal buffer is set up correctly and avoids
140 +   a duplicate initial row.
141 +
142 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
143 +   That is, the DataSize should be the field size * character set width. The
144 +   value returned by DataSize is now the same as the Dataset buffer size reserved
145 +   for the field.
146 +
147 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
148 +
149 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
150 +    and vice-versa. This may result in an exception being raised (correctly) for
151 +    older programs when using dataset fields added to a form and the database has been
152 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
153 +    In such cases, the field needs to be deleted in the IDE fields editor and then
154 +    added back in.
155 +
156 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
157 +    false if query contains only white space and not just empty.
158 +
159 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
160 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
161 +    is cancelled.
162 +
163 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
164 +    called on a null field.
165 +
166 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
167 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
168 + set.
169 +
170 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
171 +    a cached update is applied and an exception is raised.
172 +
173 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
174 +
175 + 17. Console Mode Local Database support: backup/restore should now work correctly.
176 +
177 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
178 +    possible and an exception raised.
179 +
180 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
181 +    below this version no. and upgrade not possible.
182 +
183 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
184 +
185 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
186 +    not SQL Identifiers are now supported.
187 +
188 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
189 +    passed to the Firebird engine for execution.
190 +
191 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
192 +    is made to scroll back.
193 +
194 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
195 +
196 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
197 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
198 +
199 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
200 +   validated. If no match is found in the list of field names and the database has
201 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
202 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
203 +
204 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
205 +   with fpc 3.2.
206 +
207 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
208 +
209 +
210 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
211 +   and is used to override the default settings in the client side "firebird.conf" This
212 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
213 +   Each line of the string list should be a setting in the same format as "firebird.conf".
214 +   For example "WireCompression = true" in order to request wire compression on the client side.
215 +
216 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
217 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
218 +   also require a compatible setting in the server side "firebird.conf". For example
219 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
220 +   compression to be used.
221 +
222 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
223 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
224 +   ibx/examples/dbinfo for examples of how to display this information.
225 +
226 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
227 +   is a "convenience" property. If set the "WireCompression=true" is added to the
228 +   ConfigOverrides. If unchecked then this setting is removed.
229 +
230 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
231 +   not "INT64".
232 +
233 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
234 +   These are:
235 +    property TimestampFormat: string;
236 +    property DateFormat: string;
237 +    property TimeFormat: string;
238 +
239 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
240 +   DATETIME and TIME. The format strings use the standard FPC date/time format
241 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
242 +
243 +   If any of the above properties are set to an empty string, then the locale default
244 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
245 +   locale default is extended by appending '.zzz' to include milliseconds.
246 +
247 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
248 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
249 +
250 + 5. New published property for TIBCSVDataOut:
251 +     property QuoteStrings: boolean (default true)
252 +
253 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
254 +   used to delimit each and every string in the output.
255 +
256 + 6. New published properties for TIBCSVDataOut:
257 +    property FieldSeparator: string;
258 +    property HeaderSeparator: string;
259 +
260 +   Respectively, these provide the separator character(s) used to separate fields
261 +   in data and header rows. Both default to ','.
262 +
263 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
264 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
265 +    property OnFormatTextString;
266 +
267 +   This event handler can be used to process text strings before they are included
268 +   in the output e.g. to replace unprintable characters with alternative strings.
269 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
270 +
271 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
272 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
273 +   and without raising and exception if it does not.
274 +
275 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
276 +   consistency with SQL queries.
277 +
278 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
279 +    When true, SQL statement parameter names are parsed case sensitive. Note for
280 +    TIBDataSet only applies to Select query.
281 +
282 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
283 +    an IDE exception.
284 +
285 + 12. LocalDBSupport: initial database creation should now work correctly
286 +    when the schema source is an sql file.
287 +
288 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
289 +    when defined, this handler will be called by the internal TIBXScript during
290 +    initial database creation when the schema source is an sql file and may be used
291 +    to provide a visual indication of progress in console mode.
292 +
293 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
294 +    to true while a new local database is being created and its schema populated.
295 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
296 +    when the database is disconnected/connected during the create DB procedure.
297 +
298 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
299 +    are now always ignored and replaced by the user name and password provided as
300 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
301 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
302 +    completely ignored if this property is true.
303 +
304 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
305 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
306 +    ImageIndex and SelectImageIndex values on AddNode.
307 +
308 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
309 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
310 +    the same database connection.
311 +
312 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
313 +    if provided, this should be an conditional SQL expression suitable for
314 +    including in an SQL Select statement "where" clause. If non-empty and the
315 +    "Filtered" property is true then the SQL expression provided as the value of
316 +    the "Filter" property is "ANDed" with any existing condition statement
317 +    in the SQL statement's "Where" clause.
318 +
319 +    If the "Filter" property is set at run time, the "Filtered" property is true
320 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
321 +
322 +    The "Filter" condition may include IBX style parameters. In which case, their
323 +    value must be set by the dataset's "OnBeforeOpen" event handler.
324 +
325 +    This is a public property for TIBDataSet and TIBQuery query and intended for
326 +    use at run time.
327 +
328 +    Note: The property is a published property of TIBTable. The TIBTable functionality
329 +    is unaffected by this change.
330 +
331 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
332 +
333 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
334 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
335 +   mode apps.
336 +
337 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
338 +   statement. This avoids problems if "Execute Block" is used as the Query.
339 +
340 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
341 +   internal SQL tokeniser routines.
342 +
343 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
344 +   as a select statement, with or without CTEs.
345 +
346 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
347 +
348 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
349 +   internal SQL tokeniser routines.
350 +
351 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
352 +    being raised for valid set statements processed by a data formatter.
353 +
354 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
355 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
356 +   the path of the Firebird Library used by the database/services connection.
357 +
358 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
359 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
360 +   services connection.
361 +
362 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
363 +   or param name is not a valid SQL identifier.
364 +
365 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
366 +    view of whether the text box should be editable when no DataSource is specified.
367 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
368 +    ReadOnly is false, the text box is editable when no DataSource is specified.
369 +
370 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
371 +    the FBLIB environment variable. If you do not want to permit this then you
372 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
373 +    this setting.
374 +
375 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
376 +
377 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
378 +   Utf8EscapeControlChars
379 +
380 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
381 +
382 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
383 + all previous copies of the IBX source code tree before installing this release.
384 +
385 + The IBX packages used by most users have not changed, with one exception. The
386 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
387 + to use the IBServices unit in your applications, please add the iblegacyServices
388 + to the list of dependencies. To do this, open the Project Inspector and select
389 + Add->New Requirement and select "ibLegacyServices" from the list of available
390 + packages.
391 +
392 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
393 +   the IBServices unit providing what is intended to be a clearer and easier to
394 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
395 +   more information and the guide to "Firebird Service Management Using IBX".
396 +   As indicated above, the legacy services components are still available and
397 +   provided in a separate package. There is no need to update working applications
398 +   using the older versions except for an additional package dependency.
399 +
400 + 2. The IBX packages and source code tree have been re-organised in an attempt to
401 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
402 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
403 +   new set of IBX packages.
404 +
405 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
406 +   updated to use the new Services API components.
407 +
408 + 4. The iblocal package has been updated to use the new Services API components.
409 +
410 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
411 +   TIBXSecurityService. It had been wrongly classified in the previous version
412 +   as a per database configuration item. It is global to a server and hence
413 +   correctly positioned as part of the Security Package. In the DBAdmin example,
414 +   the setting has moved to the mappings page.
415 +
416 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
417 +   are ignored.
418 +
419 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
420 +   closed before the database is dropped. Before and After Disconnect event handlers
421 +   are also fired.
422 +
423 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
424 +   is started and not just the first time.
425 +
426 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
427 +   depenendency with comp type.
428 +
429 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
430 +
431 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
432 +    then this is recognised and not ignored.
433 +
434 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
435 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
436 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
437 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
438 +
439 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
440 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
441 +    counters for the select query. Note: stats accumulate after each fetch from
442 +    the database. To get total query cost after open, call the "Last" method
443 +    and then GetPerfStatistics.
444 +
445 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
446 +
447 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
448 +    in parenthesises.
449 +
450 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
451 +    SQL identifiers are always delimited by double quotes. If false, then they are
452 +    only delimited if the identifier is a reserved word, contains lower case or special
453 +    characters. Set this property to true to retain previous behaviour.
454 +
455 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
456 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
457 +
458 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
459 +       property MasterDetailDelay: integer {defaults to zero}
460 +
461 +    When non-zero and the dataset is a detail table referencing a master table
462 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
463 +    then a synchronisation delay is added (in milliseconds) between the master
464 +    row changing and the detail dataset being re-opened. If the master dataset
465 +    is scrolled before the delay expires then the delay is reset. This can be used
466 +    to avoid performance overheads when scrolling through a large master dataset.
467 +
468 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
469 +    chreads unit must be included in your project. TTimer is not used in order
470 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
471 +
472 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
473 +    with Extract Option eoDatabase.
474 +
475 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
476 +    When a deLayoutChanged event is reported on the ListSource dataset, the
477 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
478 +    relationship with the control's datasource (master).
479 +
480 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
481 +
482 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
483 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
484 +
485 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
486 +    DDL (Firebird 3 and later only).
487 +
488 + 22. TIBLookupComboBox Autocomplete Fixes:
489 +    i. Only appended text is now selected after autocomplete.
490 +    ii. Uppercase keys no longer ignored for autocomplete.
491 +    iii. Retain Prefix case is now honoured correctly.
492 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
493 +        before autocomplete performed. i.e. behaviour now the same as when
494 +        no DataSource assigned.
495 +
496 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
497 +    between SQL statements.
498 +
499 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
500 +    ObjectNames are converted to upper case before matching against metadata object
501 +    names, unless the objectname is delimited by double quotes, in which case, the
502 +    double quotes are removed and the remaining string is used (unmodified) to match
503 +    against the metadata object name.
504 +
505 +    If true then the ObjectName is used as is without modification and matched
506 +    against the metadata object name. No attempt is made to remove double quotes.
507 +
508 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
509 +    with eoTrigger, these extract types can be used to select only Database Triggers,
510 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
511 +
512 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
513 +    statement separate character is now reset to the default (';').
514 +
515 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
516 +
517 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
518 +    a commit or reconnect statement and instead activated only when next SQL statement
519 +    is executed.
520 +
521 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
522 +
523 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
524 +    converting statement to upper case.
525 +
526 + 31. TIBExtract: metadata comments now supported. New published property
527 +    IncludeMetaDataComments (default true). If true then metadata comments included
528 +    in extracted DDL. New Extract Object member eoComments. This may be used with
529 +    ExtractObject method to list all metadata comments.
530 +
531 + 32. TIBExtract: ListObjectNames method added.
532 +
533 + 33. Updated Database component editor to support additional connection string
534 +    types.
535 +
536 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
537 +
538 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
539 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
540 + RELEASE.
541 +
542 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
543 +
544 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
545 +
546 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
547 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
548 +   information). However, this is also a very useful mechanism for returning updated computed by
549 +   column values. Values returned as a result of executing an Insert or Update statement
550 +   replace existing values in the current row for each corresponding column.
551 +
552 +   Previously, if a dataset's select query included read only (computed by) fields then
553 +   an automatic row refresh was performed after an insert or update query had been processed,
554 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
555 +   that an automatic refresh is no longer performed if an insert or update query contains
556 +   a returning clause that updates one or more fields on the current row. A full row
557 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
558 +   field values and the select query contains read only fields. Use of Insert/update
559 +   returning should be significantly more efficient than executing a refresh query.
560 +
561 +   This behaviour change is intended to be backwards compatible and there should be no need to change
562 +   existing programs, other than to improve performance by using the new capability.
563 +
564 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
565 +   they are called when the dataset row is being deleted, there is no value in
566 +   updating the current record from the query result. Instead, a new event handler
567 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
568 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
569 +   by the query. The event handler can then interrogate the query results and
570 +   perform whatever action is necessary. For example to confirm, to the user,
571 +   the deletion of a row with the returned values.
572 +
573 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
574 +   any Computed By or Identity Columns. The IBTables example has been updated to
575 +   illustrate the computation of the employee Full Name on update.
576 +
577 + 5. TIBTable: The GeneratorField property is now published.
578 +
579 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
580 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
581 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
582 +   each Identity column after the insert is executed.
583 +
584 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
585 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
586 +   Insert..Returning clause.
587 +
588 + 8. TIBGenerator: small performance improvement by not preparing query each time
589 +   a new value is generated.
590 +
591 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
592 +
593 + 10. Property editors will now sync table name to a System Table when "Include System
594 +    Tables" is selected and the query is for a System Table.
595 +
596 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
597 +    values are no longer converted to milliseconds from TDateTime and then back again
598 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
599 +
600 + 12. Property Editors handling of Stored Procedures.
601 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
602 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
603 +      query).
604 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
605 +
606 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
607 +    can be used to select a package. If non-empty, the stored procedure name is
608 +    expected to be a stored procedure defined in the specified package and the
609 +    generated SQL will be as required for a stored procedure located in a package.
610 +
611 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
612 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
613 +    which a stored procedure can be selected. With no package name selected, non-package
614 +    stored procedures are listed.
615 +
616 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
617 +    for password on reconnect.
618 +
619 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
620 +    and character set name.
621 +
622 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
623 +    DB info lookups"
624 +
625 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
626 +
627 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
628 +
629 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
630 +    parameters. This stops an exception being raised when the field cannot be
631 +    located in the record buffer.
632 +
633 + 21. Property Editors now automatically include System Tables when opened and when the query table
634 +    is a System Table.
635 +
636 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
637 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
638 +
639 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
640 +    add the SPB item isc_spb_expected_db. This names a database using
641 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
642 +    database. examples/services re-written to illustrate use of "expected_db".
643 +
644 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
645 +    This avoids truncated backups when the server returns a timeout (busy) response.
646 +
647 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
648 +
649 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
650 +    databasenames. These are respectively expanded to the local system's temp directory
651 +    (including trailing delimiter) or to a prescribed data directory (including
652 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
653 +    in the user's home directory. The hidden directory name is either the string returned
654 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
655 +    Under Windows, the directory is the same as the Data Directory as decribed
656 +    above but instead prefixed by the User's application data path. These may be
657 +    used to improve application portability for Personal Databases.
658 +
659 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
660 +    this has not worked for a long time and is not useful either. FieldDefs should be
661 +    managed using the Fields Editor as with any other dataset. To access the fields
662 +    editor for a TIBTable component, double click on the component. The fields editor
663 +    is then displayed.
664 +
665 + 28. TIBDatabaseInfo: new properties/function
666 +     * DateDBCreated (returns date/time database created)
667 +     * TransactionCount (returns no. of active transactions)
668 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
669 +     * PagesFree (Firebird 3 or later)
670 +     * PagesUsed (Firebird 3 or later)
671 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
672 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
673 +
674 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
675 +
676 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
677 +
678 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
679 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
680 +
681 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
682 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
683 +    firing during backup and restore.
684 +
685 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
686 +    for verbose output using the new property "StatisticsRequested".
687 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
688 +
689 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
690 +
691 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
692 +    palette. This uses the online validation feature added in Firebird 2.5. The
693 +    services's properties enable inclusion/exclusion of tables and indexes using
694 +    regular expressions. See.
695 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
696 +
697 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
698 +    option on a database.
699 +
700 + 37. TIBCustomService: Assign method implemented to allow copying of service login
701 +    context between service API components. "Detach" method now only detaches
702 +    service when last reference to the service interface detaches. Tidy up of
703 +    code for SetActive and Attach methods including password hiding.
704 +
705 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
706 +    and used to determine the auth method and protocol used for the connection.
707 +
708 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
709 +    a Create Database Statement generated by IBX.
710 +
711 + 40. All IBServices now have an additional published property "PortNo". This may
712 +    be set to a non-standard port number when necessary. If zero then the default
713 +    port number is used.
714 +
715 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
716 +    and not just the mouse.
717 +
718 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
719 +
720 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
721 +    image index and selected image index for each node to be set from a database field.
722 +
723 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
724 +    then database schema includes grants to all users. If not present then the
725 +    only user grants included are those to User PUBLIC.
726 +
727 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
728 +    and child nodes in dataset.
729 +
730 +
731 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
732 +
733 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
734 +   changes.
735 +
736 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
737 +   Bug could result in truncated multi-byte character set values.
738 +
739 + 3. Changes consequential on moving fbintf character set utility functions from
740 +   IFirebirdAPI to IAttachment.
741 +
742 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
743 +
744 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
745 +   results in autocomplete ignoring prefix text.
746 +
747 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
748 +   entering a new name into the text box.
749 +
750 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
751 +   Firebird rather than recomputing it.
752 +
753 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
754 +   screen centre. Previously some were "poDesigned" which may be inappropriate
755 +   for multi monitor desktops.
756 +
757 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
758 +
759 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
760 +    a transaction and always reset the object.
761 +
762 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
763 +
764 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
765 +
766 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
767 +    to a gbak format archive.
768 +
769 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
770 +
771 + 16. IBLocaldb: Drop database if error creating an empty database.
772 +
773 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
774 +    unless selected node not in current dataset.
775 +
776 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
777 +    to TIBCustomService, and IBlocalDB code tidy up.
778 +
779 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
780 +    behaviour due to uninitialised variable.
781 +
782 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
783 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
784 +
785 + 21. IBSQL: When Database changed ensure that all resources are freed.
786 +
787 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
788 +
789 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
790 +    * Line Wrap on SQL Token boundaries (on user command)
791 +    * auto-complete table names in drop down list of table names
792 +    * Double click on tablename or field name adds to SQL text
793 +
794 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
795 +
796 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
797 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
798 +    workaround for a problem in fpc 3.0.4 win64).
799 +
800 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
801 +
802 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
803 +
804 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
805 +
806 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
807 +   include remote system name.
808 +
809 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
810 +   tables when data included in output.
811 +
812 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
813 +   and timing information to be written to stdout. This may be used to locate
814 +   performance bottlenecks.
815 +
816 + 4. SQLParser: only call "OnChanging" event handler when value is different.
817 +
818 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
819 +
820 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
821 +   that BindFields is called when the query is next activated. Avoids FieldName
822 +   not found error.
823 +
824 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
825 +   purpose and allows the programmer to define any action they want for Update, Insert
826 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
827 +   filtering of updates, or use of statements such as Grant or Revoke instead of
828 +   normal DML. See User Manual for more information.
829 +
830 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
831 +
832 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
833 +
834 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
835 +
836 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
837 +   hexadecimal notation.
838 +
839 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
840 +   using a simple XML format.
841 +
842 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
843 +   grants to these objects.
844 +
845 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
846 +   dependency problems restoring complex databases.
847 +
848 + 7. TIBXScript: This component has been restructured to allow for the processing of
849 +   embedded XML in INSERT statements and to support interactive sources in addition
850 +   to non-interactive data sources such as files.
851 +
852 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
853 +
854 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
855 +   SET SQL DIALECT
856 +   SET TERM
857 +   SET AUTODDL
858 +   SET BAIL
859 +   SET ECHO
860 +   SET COUNT
861 +   SET STATS
862 +   SET NAMES <character set>
863 +
864 + 10. IBVersion unit added to hold current IBX Version Number information.
865 +
866 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
867 +    and domain definitions.
868 +
869 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
870 +    fully supported.
871 +
872 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
873 +
874 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
875 +
876 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
877 +
878 + See also doc/IBX4LazarusGuide.pdf for important information on
879 + upgrading to IBX2.
880 +
881 + 1. Size property of TIBStringField is now the width in characters of the field
882 +   and not the byte length. This applies only to multi-byte character sets such
883 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
884 +   code is not recognised as a bug and hence this change to align the behaviour.
885 +   The TStringField change is expected in fpc 3.2.0.
886 +
887 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
888 +   true (default) then Size property value saved in the lfm is ignored. Size is
889 +   always set from the dynamic information read from the database. It is unclear
890 +   why anyone would want to override this and set Size to false.
891 +
892 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
893 +   block.
894 +
895 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
896 +   exist when an attempt is made to connect to it (run time only) then an attempt
897 +   is made to create the database.
898 +
899 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
900 +   has been successfully created as a result of a call to CreateDatabase or when
901 +   creating a database after it was found not to exist.
902 +
903 + 6.  DBControlGrid: a race condition could result in the wrong row image being
904 +    written to the cache. This has been avoided by a trip round the message
905 +    loop before rendering the row image.
906 +
907 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
908 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
909 +    known to risk corrupt rendering of row images when the control is first
910 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
911 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
912 +
913 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
914 +    a TDateEdit control located on an editor panel.
915 +
916 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
917 +
918 + 10. DBControlGrid: Removed memory leak when updating rows.
919 +
920 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
921 +
922 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
923 +
924 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
925 +   when target codepage is CP_NONE. This is a workaround for
926 +   http://bugs.freepascal.org/view.php?id=30622.
927 +
928 + 2. DBLog option removed from TIBStatisticalService - not supported by server
929 +   since Firebird 1.5.
930 +
931 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
932 +   similar.
933 +
934 + 4. IBCodePage: updated mapping between codepages and character id.
935 +
936 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
937 +   Firebird. Character sets with a char width of two are not UTF16.
938 +
939 + 6. Strings received from the database are now always transliterated into UTF8
940 +   regardless of the database character set or connection character set. This
941 +   is for compatibility with the LCL.
942 +
943 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
944 +
945 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
946 +   read in an entire blob just to get the size of the blob. General performance
947 +   improvement when opening datasets containing blobs.
948 +
949 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
950 +
951 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
952 +   is now used.
953 +
954 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
955 +   determined.
956 +
957 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
958 +
959 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
960 +   lazarus 1.6.0
961 +
962 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
963 +   compilation error.
964 +
965 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
966 +
967 + 1. No character set specified for connection: when a text blob is retrieved, the
968 +  character set is determined by looking up the native character set using then
969 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
970 +  set as the connection.
971 +
972 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
973 +   for Login Dialog returing a change to the database path.
974 +
975 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
976 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
977 +   entered value to be saved on a project specific basis (design time only).
978 +
979 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
980 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
981 +   Otherwise, it sets the column text to the selected ListField Value.
982 +
983 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
984 +   column width.
985 +
986 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
987 +   and a case insensitive search is requested.
988 +
989 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
990 +   or column ListSource.
991 +
992 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
993 +   unprepare) when closing and the text has not changed.
994 +
995 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
996 +   Less likely to cause a cursor re-use error on Windows.
997 +
998 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
999 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1000 +
1001 + 11. TIBTreeView: Guard against nil destination on record changed
1002 +
1003 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1004 +    string type with the code page set to reflect the returned field encoding after
1005 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1006 +    earlier versions.
1007 +
1008 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1009 +    will now result in transliteration to the code page specified for the Firebird driver
1010 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1011 +
1012 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1013 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
1014 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1015 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1016 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1017 +    the GETACP is used to determine the Windows code page.
1018 +
1019 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1020 +    name used as the lc_ctype when the database was opened. Only valid while the
1021 +    Database is connected.
1022 +
1023 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1024 +    id that corresponds to the DefaultCharSetName.
1025 +
1026 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1027 +
1028 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1029 +   path is given and database attach fails due to access permission issues on the
1030 +   temp directory or security database, then the attach is retried with "localhost:"
1031 +   prefixing the databasename. This should avoid problems when the database has to
1032 +   be accessed by a local (e.g. classic) server and libfbembed is used.
1033 +
1034 + 2. Windows: revised search order for Firebird DLL:
1035 +     i.   The Firebird Embedded Server in the application Directory.
1036 +     ii.  If the FIREBIRD environment variable is set then the directory this
1037 +          points to is searched for the FB Client DLL and then then underlying
1038 +          "bin" directory.
1039 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1040 +          is used to locate the Firebird installation directory and the underlying
1041 +          "bin" directory is searched for the FB Client DLL.
1042 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1043 +          are searched for the FB Client DLL.
1044 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
1045 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1046 +
1047 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1048 +   See doc/readme.scriptengine and example applications.
1049 +
1050 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1051 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
1052 +   See dpc/readme.localdatabase and example applications.
1053 +
1054 + 5. IBDynamicGrid: Reordering on column header click should now also work for
1055 +   dynamic columns.
1056 +
1057 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1058 +   between incrementing/decrementing the lock count and signalling the event.
1059 +
1060 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1061 +
1062 + 1.3.2 was never formally released and only made available as beta copies.
1063 +
1064 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1065 +
1066 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1067 +
1068 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1069 +
1070 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1071 +   i.e. when it is a calculated field
1072 +
1073 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1074 +   This problem was due to a race condition between recalculating row heights and
1075 +   determining which row was selected by the mouse click. The row height calculation
1076 +   is now deferred by an extra trip round the message loop allowing the row to
1077 +   be always calculated on the current grid layout rather than risking it being
1078 +   calculated on the grid layout after the expanded row has been shrunk.
1079 +
1080 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1081 +   Windows.
1082 +
1083 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1084 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1085 +   to be determined at runtime. See doc/readme.charactersets.html.
1086 +
1087 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1088 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1089 +
1090 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1091 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1092 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1093 +
1094 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1095 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1096 +   implies no truncation.
1097 +
1098 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1099 +
1100 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1101 +   (avoids "Not in Edit Mode" error).
1102 +
1103 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1104 +
1105 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1106 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1107 +
1108 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1109 +
1110 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1111 +
1112 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1113 +
1114 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1115 +
