2    
3     1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
4     if ApplyUpdates called before a cursor exists.
5    
6     2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
7     creating the blob.
8    
9 tony 421 IBX Change Log version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
10    
11     1. Update to calls to EInterbaseError to add default code page. Consequential
12     on change to fbintf.
13    
14     2. Update some examples to replace test for null date with the NullDate constant
15     instead of zero. This is because Laz 3.0 changes the value of NullDate.
16    
17 tony 419 IBX Change Log version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
18 tony 416
19     1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
20 tony 418 with later versions of fpc - later than 3.2.2.
21 tony 416
22 tony 418 2. IBUpdateSQL. update internal queries if parent dataset database changed.
23    
24     3. IBUpdateSQL: Do not prepare an empty internal query.
25    
26 tony 419 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
27 tony 418
28 tony 419 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
29    
30 tony 412 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
31    
32     1. Maintenance update of 2.6.0. This version is still at beta.
33    
34     2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
35     See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
36    
37     3. ibxscript: When parsing a store procedure or function with a variable name
38     enclosed in doublequotes, the double quotes are no longer removed.
39    
40 tony 410 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
41 tony 407
42 tony 410 NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
43     AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
44     BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
45     ISSUES TO support@mwasoftware.co.uk
46    
47     1. Complete rewrite of internal buffer management in order to improve performance
48     and maintainability. Highlights:
49    
50     * Extending the size of the buffer pool no longer has to copy the entire record
51     cache. Instead, a new extent is simply added to the buffer pool.
52     * A memory to memory copy of each display buffer now is avoided when scolling the
53     dataset.
54     * A separate set of buffers is now used for calculated fields. This avoids
55     having to keep copies of calculated field values in the buffer cache.
56     * Compact bitmaps are used to record null status and need to refresh in each
57     buffer.
58     * Display buffer type changed from PChar to TRecordBuffer in line with change of
59     buffer type in FCL-DB.
60    
61     2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
62     to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
63    
64     3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
65     If either or both of these flags are set at design time (using the fields editor)
66     then this forces a row refresh on respectively insert or update, or both, when the
67     corresponding field is not present in an SQL RETURNING clause.
68    
69     4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
70     maintainability and readability and to add identification of primary key fields.
71    
72     5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
73     as a refresh of the current row. However, this is different behaviour to that described
74     in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
75     the dataset from the underlying database, and attempts to reposition the cursor on
76     the same record as it was". IBX now complies with the FPC definition of Refresh.
77    
78     6. A progammatic Row Refresh should no longer be required.
79     Use Insert/Update... returning to refresh any fields that may change following an
80     insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
81     on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
82     for the field at Design Time to force a row refresh if not in the returning clause.
83    
84     7. It should now be possible to insert a row into an empty unidirectional dataset.
85    
86     8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
87     This gives the number of buffers in the initial block for the buffer pool in
88     bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
89     in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
90     for small datasets.
91    
92     IBX Change Log version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
93    
94 tony 407 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
95    
96     2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
97    
98 tony 409 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
99    
100 tony 402 IBX Change Log version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
101    
102     1. TIBTransaction: new properties
103     property TransactionID: integer read GetTransactionID;
104     property IsReadOnly: boolean read GetIsReadOnly;
105     {published}
106     property TransactionName: string read FTransactionName write SetTransactionName;
107    
108     2. IBCustomDataset: per row blob and array buffer cached clear before processing
109     Insert or Update...Returning. This allows blobs and arrays to be returned
110     by the statement.
111    
112     3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
113    
114     4. TransactionName initialised to a newly generated GUID if empty.
115    
116     5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
117     for the fbintf package's journaling capability. TIBJournal is used to set the
118     file path and filename for the journal file and to Enabled (start journaling) and
119     disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
120     more information, and comments in IBJournal.pas.
121    
122     6. TIBDatabase.InternalTransaction is now a read only transaction.
123    
124     7. Bug fix: blob id no longer set to null on update when blob has not been
125     retrieved.
126    
127     8. Row auto refreshed on update/insert if blob or array field updated and field
128     not in a returning clause.
129    
130     9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
131     buffer overhead and avoids problem when refresh query has a different column
132     count to select query i.e. incorrectly changing number of columns.
133    
134     10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
135    
136     11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
137     string. Note that the Version property returns an InterBase compatible version string.
138    
139     12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
140    
141 tony 359 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
142    
143     1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
144     This is for compatibility with Firebird 5 where Update...Returning can return
145     a cursor.
146    
147 tony 356 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
148 tony 347
149     1. Add try-..except check when initially loading library in IDE. This should
150     ensure that IDE continues to load even when a failure occurs in IBX load
151     library.
152    
153 tony 348 2. IBXScript: now recognises a CASE...END block within a stored procedure and
154     hence will correctly detect end of the outer containing block when the block
155     contains a SELECT ... CASE ... END construct.
156    
157     3. IBExtract: some further tidying up to remove extraneous white space.
158    
159 tony 349 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
160     errors when extra elements are added to DB.TFieldType.
161    
162     5. IBUpdate: updated to reflect changes to ISQLParam.
163    
164     6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
165    
166     7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
167    
168 tony 353 8. IBSQL: Support for scrollable cursors added (note: local databases only)
169    
170 tony 345 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
171    
172     1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
173     exception of those defined to be one byte wide e.g. DBImplementationNo.
174    
175     2. TIBSQL: Batch Update/Insert support added.
176    
177     3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
178     is no longer automatically converted to upper case when it is syntactically a
179     SQL Identifier. This is to support the use of stored procedures defined e.g.
180     as CREATE PROCEDURE "iCASE".
181    
182     There could be a backwards compatibility issue when the StoredProcName was entered
183     manually at design time. That is not selected from the drop down list. If the
184     StoredProcName is entered in mixed case and the procedure was declared e.g. as
185     CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
186     ensure that the value of the StoredProcName is all upper case, unless it was
187     declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
188     quotes).
189    
190     Note that when a stored procedure name was declared delimited in double quotes,
191     as in the first example above, the value of the StoredProcName property must not
192     include the delimiters (double quotes).
193    
194     4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
195     upgrade.conf was not found. This replaces silently ignoring the problem.
196    
197     5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
198     'Version.%.3d' and is used to generate the section header names (for a given
199     version no.) in the upgrade.conf file.
200    
201 tony 340 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
202    
203     1. -c command line option added to fbsql example program. Used to set connection
204     character set.
205    
206 tony 338 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
207 tony 315
208     1. Firebird 4 support added.
209    
210     2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
211     extended precision NUMERIC fields are supported.
212    
213     3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
214    
215     4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
216     and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
217    
218     5. IBExtract now supports FB4 enhancements:
219     - new data types as above
220     - Identity column extensions
221     - Default user role
222     - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
223     - Internal Functions
224    
225     6. IBExtract: new event: OnExtractLines.
226    
227     7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
228    
229     8. IBXServices: Server version no. parsing now allows any letter before major version number
230     and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
231    
232     9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
233     format for rendering a time zone.
234    
235     10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
236     to convert TIME WITH TIME ZONE data type values to and from GMT.
237    
238     11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
239     IIBGUIInterface and IIBTimerInf respectively.
240    
241     12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
242     now accessible as properties of TIBDatabase and TIBTransaction respectively.
243    
244     13. String Fields: when a fixed character with (CHAR) field is returned, it is now
245     truncated to its fixed character width rather than being right padded with
246     white space to the maximum data size.
247    
248     14. TIBTable.Empty table. In additional to deleting all records in the underlying
249     table, the internal buffers are now also flushed ensuring that the TIBTable is
250     also empty.
251    
252     15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
253    
254     16. TIBXControlService descendents: DatabaseName may now be set using a database
255     connect string. The database name is extracted from the connect string.
256    
257     17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
258    
259     18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
260    
261     19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
262     not being present as required.
263    
264     20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
265     version that can be customised to work with other database drivers.
266    
267 tony 319 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
268     unnecessary CR at end of line on Unix platforms.
269    
270     22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
271     seconds in order to reduce risk of message loss.
272    
273     23. ISQLMonitor: read and write count statistics now available via:
274     property TIBSQLMonitor.ReadCount;
275     IIBSQLMonitorHook.GetWriteCount: integer;
276    
277     24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
278    
279 tony 312 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
280 tony 308
281     1. TIBStringField: when a string value is read from a dataset buffer, if the
282     number of UTF8 characters exceeds the string size then string is truncated
283     to the maximum string size. This is usually a problem with fixed width columns
284     right padded with white space.
285    
286     2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
287     If SQLFiltered is set then when a dataset is opened, each line in the
288     SQLFilterParams property is assumed to be a SQL condition clause and
289     ANDed into the Where clause of the SQL Select statement provided as a
290     dataset property. Each such SQL condition thus acts as an additional filter
291 tony 315 on the dataset.
292 tony 308
293     3. The Filtered property inherited from TDataset is no longer used for SQL (server
294     side filters).
295    
296 tony 311 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
297     text matches complete entry.
298    
299     5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
300     dataset are active (avoids risk of access violation if master is inactive)
301    
302     6. TIBEvents: Registered property can now be set at design time even if database not open
303    
304     7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
305     This should prevent "spillover" of events between sessions.
306    
307     8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
308     This should ensure that the internal buffer is set up correctly and avoids
309     a duplicate initial row.
310    
311     9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
312     That is, the DataSize should be the field size * character set width. The
313     value returned by DataSize is now the same as the Dataset buffer size reserved
314     for the field.
315    
316 tony 312 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
317 tony 311
318     11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
319     and vice-versa. This may result in an exception being raised (correctly) for
320     older programs when using dataset fields added to a form and the database has been
321     upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
322     In such cases, the field needs to be deleted in the IDE fields editor and then
323     added back in.
324    
325 tony 312 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
326 tony 315 false if query contains only white space and not just empty.
327 tony 312
328 tony 311 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
329     should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
330     is cancelled.
331    
332 tony 315 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
333     called on a null field.
334    
335     14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
336     results in an empty dataTC86 Client side Filtered Dataset 1 X
337     set.
338    
339     15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
340     a cached update is applied and an exception is raised.
341    
342     16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
343    
344     17. Console Mode Local Database support: backup/restore should now work correctly.
345    
346     18. Local Database Support: if an upgrade fails, a downgrade is now performed if
347     possible and an exception raised.
348    
349     19. MinimumVersionNo added to Local Database Support. Database will not open if
350     below this version no. and upgrade not possible.
351    
352 tony 307 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
353 tony 306
354 tony 307 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
355     not SQL Identifiers are now supported.
356 tony 306
357 tony 307 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
358     passed to the Firebird engine for execution.
359 tony 306
360 tony 307 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
361     is made to scroll back.
362 tony 306
363 tony 307 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
364 tony 306
365 tony 307 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
366     only enclosed in double quotes in SQL dialect 3 and when it needs to be.
367 tony 306
368 tony 307 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
369     validated. If no match is found in the list of field names and the database has
370     been opened in SQL Dialect 3, then the ListField Name is converted to upper case
371     if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
372 tony 306
373 tony 307 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
374     with fpc 3.2.
375 tony 306
376 tony 307 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
377 tony 287
378    
379 tony 307 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
380     and is used to override the default settings in the client side "firebird.conf" This
381     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
382     Each line of the string list should be a setting in the same format as "firebird.conf".
383     For example "WireCompression = true" in order to request wire compression on the client side.
384 tony 287
385 tony 307 Note: explicit settings in the client side "firebird.conf" appear to take precedence
386     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
387     also require a compatible setting in the server side "firebird.conf". For example
388     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
389     compression to be used.
390 tony 291
391 tony 307 Whether or not WireCompression or WireCrypt are in use can be checked using the information
392     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
393     ibx/examples/dbinfo for examples of how to display this information.
394 tony 291
395 tony 307 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
396     is a "convenience" property. If set the "WireCompression=true" is added to the
397     ConfigOverrides. If unchecked then this setting is removed.
398 tony 291
399 tony 307 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
400     not "INT64".
401 tony 291
402 tony 307 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
403     These are:
404     property TimestampFormat: string;
405     property DateFormat: string;
406     property TimeFormat: string;
407 tony 291
408 tony 307 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
409     DATETIME and TIME. The format strings use the standard FPC date/time format
410     characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
411 tony 266
412 tony 307 If any of the above properties are set to an empty string, then the locale default
413     is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
414     locale default is extended by appending '.zzz' to include milliseconds.
415 tony 272
416 tony 307 TIBCSVDataOut by default sets these properties to the empty string, while the other
417     two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
418 tony 266
419 tony 307 5. New published property for TIBCSVDataOut:
420     property QuoteStrings: boolean (default true)
421 tony 266
422 tony 307 If false then strings are unquoted, otherwise, the QuoteChar property value is
423     used to delimit each and every string in the output.
424 tony 263
425 tony 307 6. New published properties for TIBCSVDataOut:
426     property FieldSeparator: string;
427     property HeaderSeparator: string;
428 tony 267
429 tony 307 Respectively, these provide the separator character(s) used to separate fields
430     in data and header rows. Both default to ','.
431 tony 270
432 tony 307 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
433     TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
434     property OnFormatTextString;
435 tony 270
436 tony 307 This event handler can be used to process text strings before they are included
437     in the output e.g. to replace unprintable characters with alternative strings.
438     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
439 tony 270
440 tony 307 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
441     Uses "FindParam" if in order to find out if a parameter with a given name exists
442     and without raising and exception if it does not.
443 tony 270
444 tony 307 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
445     consistency with SQL queries.
446 tony 270
447 tony 307 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
448     When true, SQL statement parameter names are parsed case sensitive. Note for
449     TIBDataSet only applies to Select query.
450 tony 270
451 tony 307 11. IBEvents: removing a TIBEvent component from a form should no longer result in
452     an IDE exception.
453 tony 270
454 tony 307 12. LocalDBSupport: initial database creation should now work correctly
455     when the schema source is an sql file.
456 tony 270
457 tony 307 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
458     when defined, this handler will be called by the internal TIBXScript during
459     initial database creation when the schema source is an sql file and may be used
460     to provide a visual indication of progress in console mode.
461 tony 270
462 tony 307 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
463     to true while a new local database is being created and its schema populated.
464     Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
465     when the database is disconnected/connected during the create DB procedure.
466 tony 270
467 tony 307 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
468     are now always ignored and replaced by the user name and password provided as
469     the login parameters for the TIBDatabase referenced from the TIBXScript. The
470     IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
471     completely ignored if this property is true.
472 tony 270
473 tony 307 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
474     to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
475     ImageIndex and SelectImageIndex values on AddNode.
476 tony 270
477 tony 307 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
478     read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
479     the same database connection.
480 tony 270
481 tony 307 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
482     if provided, this should be an conditional SQL expression suitable for
483     including in an SQL Select statement "where" clause. If non-empty and the
484     "Filtered" property is true then the SQL expression provided as the value of
485     the "Filter" property is "ANDed" with any existing condition statement
486     in the SQL statement's "Where" clause.
487 tony 270
488 tony 307 If the "Filter" property is set at run time, the "Filtered" property is true
489     and the dataset is already open, then the dataset is closed and re-opened automatically.
490 tony 271
491 tony 307 The "Filter" condition may include IBX style parameters. In which case, their
492     value must be set by the dataset's "OnBeforeOpen" event handler.
493 tony 272
494 tony 307 This is a public property for TIBDataSet and TIBQuery query and intended for
495     use at run time.
496 tony 272
497 tony 307 Note: The property is a published property of TIBTable. The TIBTable functionality
498     is unaffected by this change.
499 tony 272
500 tony 307 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
501 tony 272
502 tony 307 1. Remove need to check for IsMultiThread by providing access to GUI timers via
503     IBGUIInterface. Note: master/detail delay timer does not apply to console
504     mode apps.
505 tony 272
506 tony 307 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
507     statement. This avoids problems if "Execute Block" is used as the Query.
508 tony 272
509 tony 307 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
510     internal SQL tokeniser routines.
511 tony 272
512 tony 307 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
513     as a select statement, with or without CTEs.
514 tony 272
515 tony 307 5. IBSQLParser: parser now recognises the "ROWS" clause.
516 tony 272
517 tony 307 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
518     internal SQL tokeniser routines.
519 tony 272
520 tony 307 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
521     being raised for valid set statements processed by a data formatter.
522 tony 272
523 tony 307 8. New published property for TIBDatabase and TIBXServicesConnection. This is
524     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
525     the path of the Firebird Library used by the database/services connection.
526 tony 267
527 tony 307 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
528     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
529     services connection.
530 tony 263
531 tony 307 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
532     or param name is not a valid SQL identifier.
533 tony 263
534 tony 307 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
535     view of whether the text box should be editable when no DataSource is specified.
536     TIBLookupComboEditBox has been updated to workaround this problem. As long as
537     ReadOnly is false, the text box is editable when no DataSource is specified.
538 tony 263
539 tony 307 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
540     the FBLIB environment variable. If you do not want to permit this then you
541     must modify the Register procedure in the design/IBDBReg.pas unit to remove
542     this setting.
543 tony 263
544 tony 307 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
545 tony 263
546 tony 307 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
547     Utf8EscapeControlChars
548 tony 263
549 tony 307 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
550 tony 263
551 tony 307 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
552     all previous copies of the IBX source code tree before installing this release.
553 tony 263
554 tony 307 The IBX packages used by most users have not changed, with one exception. The
555     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
556     to use the IBServices unit in your applications, please add the iblegacyServices
557     to the list of dependencies. To do this, open the Project Inspector and select
558     Add->New Requirement and select "ibLegacyServices" from the list of available
559     packages.
560 tony 263
561 tony 307 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
562     the IBServices unit providing what is intended to be a clearer and easier to
563     use set of IB Services components. See Chapter 10 of the IBX User Guide for
564     more information and the guide to "Firebird Service Management Using IBX".
565     As indicated above, the legacy services components are still available and
566     provided in a separate package. There is no need to update working applications
567     using the older versions except for an additional package dependency.
568 tony 263
569 tony 307 2. The IBX packages and source code tree have been re-organised in an attempt to
570     finally get rid of the "duplicate ppu" warnings. This re-organisation should
571     not affect existing users. Section 2.3 of the IBX User Guide describes the
572     new set of IBX packages.
573 tony 263
574 tony 307 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
575     updated to use the new Services API components.
576 tony 263
577 tony 307 4. The iblocal package has been updated to use the new Services API components.
578 tony 241
579 tony 307 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
580     TIBXSecurityService. It had been wrongly classified in the previous version
581     as a per database configuration item. It is global to a server and hence
582     correctly positioned as part of the Security Package. In the DBAdmin example,
583     the setting has moved to the mappings page.
584 tony 241
585 tony 307 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
586     are ignored.
587 tony 101
588 tony 307 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
589     closed before the database is dropped. Before and After Disconnect event handlers
590     are also fired.
591 tony 209
592 tony 307 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
593     is started and not just the first time.
594 tony 209
595 tony 307 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
596     depenendency with comp type.
597 tony 209
598 tony 307 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
599 tony 209
600 tony 307 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
601     then this is recognised and not ignored.
602 tony 209
603 tony 307 12. TIBDataSet, TIBQuery, TIBTable: additions:
604     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
605     function GetPerfStatistics(var stats: TPerfCounters): boolean;
606     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
607 tony 209
608 tony 307 GetRowsAffected returns the affected row counts from the last insert/update/delete
609     if EnableStatistics = true then GetPerfStatistics returns the current stats
610     counters for the select query. Note: stats accumulate after each fetch from
611     the database. To get total query cost after open, call the "Last" method
612     and then GetPerfStatistics.
613 tony 209
614 tony 307 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
615 tony 209
616 tony 307 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
617     in parenthesises.
618 tony 209
619 tony 307 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
620     SQL identifiers are always delimited by double quotes. If false, then they are
621     only delimited if the identifier is a reserved word, contains lower case or special
622     characters. Set this property to true to retain previous behaviour.
623 tony 209
624 tony 307 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
625     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
626 tony 209
627 tony 307 16. TIBDataSet, TIBQuery, TIBTable: addition:
628     property MasterDetailDelay: integer {defaults to zero}
629 tony 209
630 tony 307 When non-zero and the dataset is a detail table referencing a master table
631     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
632     then a synchronisation delay is added (in milliseconds) between the master
633     row changing and the detail dataset being re-opened. If the master dataset
634     is scrolled before the delay expires then the delay is reset. This can be used
635     to avoid performance overheads when scrolling through a large master dataset.
636 tony 209
637 tony 307 Note: uses fptimer and hence requires a thread manager. Under Linux the
638     chreads unit must be included in your project. TTimer is not used in order
639     to avoid an LCL dependency. Requires FPC 3.0.2 or later.
640 tony 209
641 tony 307 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
642     with Extract Option eoDatabase.
643 tony 209
644 tony 307 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
645     When a deLayoutChanged event is reported on the ListSource dataset, the
646     combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
647     relationship with the control's datasource (master).
648 tony 209
649 tony 307 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
650 tony 209
651 tony 307 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
652     stubs. Pedantic fix really, as procedures output in dependency order anyway.
653 tony 209
654 tony 307 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
655     DDL (Firebird 3 and later only).
656 tony 209
657 tony 307 22. TIBLookupComboBox Autocomplete Fixes:
658     i. Only appended text is now selected after autocomplete.
659     ii. Uppercase keys no longer ignored for autocomplete.
660     iii. Retain Prefix case is now honoured correctly.
661     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
662     before autocomplete performed. i.e. behaviour now the same as when
663     no DataSource assigned.
664 tony 209
665 tony 307 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
666     between SQL statements.
667 tony 209
668 tony 307 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
669     ObjectNames are converted to upper case before matching against metadata object
670     names, unless the objectname is delimited by double quotes, in which case, the
671     double quotes are removed and the remaining string is used (unmodified) to match
672     against the metadata object name.
673 tony 209
674 tony 307 If true then the ObjectName is used as is without modification and matched
675     against the metadata object name. No attempt is made to remove double quotes.
676 tony 209
677 tony 307 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
678     with eoTrigger, these extract types can be used to select only Database Triggers,
679     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
680 tony 209
681 tony 307 26. TIBXScript: If an exception occurs during the processing of a statement, the
682     statement separate character is now reset to the default (';').
683 tony 221
684 tony 307 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
685 tony 221
686 tony 307 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
687     a commit or reconnect statement and instead activated only when next SQL statement
688     is executed.
689 tony 221
690 tony 307 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
691 tony 225
692 tony 307 30. TIBXScript: case insensitive regex now used when matching statements instead of
693     converting statement to upper case.
694 tony 225
695 tony 307 31. TIBExtract: metadata comments now supported. New published property
696     IncludeMetaDataComments (default true). If true then metadata comments included
697     in extracted DDL. New Extract Object member eoComments. This may be used with
698     ExtractObject method to list all metadata comments.
699 tony 225
700 tony 307 32. TIBExtract: ListObjectNames method added.
701 tony 225
702 tony 307 33. Updated Database component editor to support additional connection string
703     types.
704 tony 226
705 tony 307 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
706 tony 227
707 tony 307 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
708     AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
709     RELEASE.
710 tony 229
711 tony 307 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
712 tony 229
713 tony 307 1. IBExtract: Identity columns - add additional check for null column for generator name.
714 tony 229
715 tony 307 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
716     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
717     information). However, this is also a very useful mechanism for returning updated computed by
718     column values. Values returned as a result of executing an Insert or Update statement
719     replace existing values in the current row for each corresponding column.
720 tony 229
721 tony 307 Previously, if a dataset's select query included read only (computed by) fields then
722     an automatic row refresh was performed after an insert or update query had been processed,
723     irrespective of the setting of the "ForcedUpdates" property. This has changed such
724     that an automatic refresh is no longer performed if an insert or update query contains
725     a returning clause that updates one or more fields on the current row. A full row
726     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
727     field values and the select query contains read only fields. Use of Insert/update
728     returning should be significantly more efficient than executing a refresh query.
729 tony 229
730 tony 307 This behaviour change is intended to be backwards compatible and there should be no need to change
731     existing programs, other than to improve performance by using the new capability.
732 tony 229
733 tony 307 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
734     they are called when the dataset row is being deleted, there is no value in
735     updating the current record from the query result. Instead, a new event handler
736     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
737     an OnDeleteReturning event handler is provided then it is called with the IResults returned
738     by the query. The event handler can then interrogate the query results and
739     perform whatever action is necessary. For example to confirm, to the user,
740     the deletion of a row with the returned values.
741 tony 231
742 tony 307 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
743     any Computed By or Identity Columns. The IBTables example has been updated to
744     illustrate the computation of the employee Full Name on update.
745 tony 209
746 tony 307 5. TIBTable: The GeneratorField property is now published.
747 tony 151
748 tony 307 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
749     When InsertSQL is generated, the Identity columns are not included in the list of values to
750     be inserted. A RETURNING clause is added to the insert statement to return the value of
751     each Identity column after the insert is executed.
752 tony 151
753 tony 307 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
754     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
755     Insert..Returning clause.
756 tony 101
757 tony 307 8. TIBGenerator: small performance improvement by not preparing query each time
758     a new value is generated.
759 tony 101
760 tony 307 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
761    
762     10. Property editors will now sync table name to a System Table when "Include System
763     Tables" is selected and the query is for a System Table.
764    
765     11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
766     values are no longer converted to milliseconds from TDateTime and then back again
767     to TDateTime (the conversion to milliseconds is the default TDataset approach).
768    
769     12. Property Editors handling of Stored Procedures.
770     * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
771     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
772     query).
773     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
774    
775     13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
776     can be used to select a package. If non-empty, the stored procedure name is
777     expected to be a stored procedure defined in the specified package and the
778     generated SQL will be as required for a stored procedure located in a package.
779    
780     14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
781     a "Package Name" drop down box to allow selection of a Firebird 3 Package from
782     which a stored procedure can be selected. With no package name selected, non-package
783     stored procedures are listed.
784    
785     15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
786     for password on reconnect.
787    
788     16. TIBDatabase: use IAttachment for connection default character set id, code page
789     and character set name.
790    
791     17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
792     DB info lookups"
793    
794     18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
795    
796     19. Add a property Editor for TIBUpdate.RefreshSQL.
797    
798     20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
799     parameters. This stops an exception being raised when the field cannot be
800     located in the record buffer.
801    
802     21. Property Editors now automatically include System Tables when opened and when the query table
803     is a System Table.
804    
805     22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
806     This avoids errors due to a stale SQRB or SRB being used for the next query.
807    
808     23. IBServices: Service attach parameters now include "expected_db". This is used to
809     add the SPB item isc_spb_expected_db. This names a database using
810     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
811     database. examples/services re-written to illustrate use of "expected_db".
812    
813     24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
814     This avoids truncated backups when the server returns a timeout (busy) response.
815    
816     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
817    
818     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
819     databasenames. These are respectively expanded to the local system's temp directory
820     (including trailing delimiter) or to a prescribed data directory (including
821     trailing delimiter). Under Unix systems the data directory is a hidden directory
822     in the user's home directory. The hidden directory name is either the string returned
823     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
824     Under Windows, the directory is the same as the Data Directory as decribed
825     above but instead prefixed by the User's application data path. These may be
826     used to improve application portability for Personal Databases.
827    
828     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
829     this has not worked for a long time and is not useful either. FieldDefs should be
830     managed using the Fields Editor as with any other dataset. To access the fields
831     editor for a TIBTable component, double click on the component. The fields editor
832     is then displayed.
833    
834     28. TIBDatabaseInfo: new properties/function
835     * DateDBCreated (returns date/time database created)
836     * TransactionCount (returns no. of active transactions)
837     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
838     * PagesFree (Firebird 3 or later)
839     * PagesUsed (Firebird 3 or later)
840     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
841     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
842    
843     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
844    
845     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
846    
847     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
848     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
849    
850     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
851     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
852     firing during backup and restore.
853    
854     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
855     for verbose output using the new property "StatisticsRequested".
856     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
857    
858     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
859    
860     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
861     palette. This uses the online validation feature added in Firebird 2.5. The
862     services's properties enable inclusion/exclusion of tables and indexes using
863     regular expressions. See.
864     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
865    
866     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
867     option on a database.
868    
869     37. TIBCustomService: Assign method implemented to allow copying of service login
870     context between service API components. "Detach" method now only detaches
871     service when last reference to the service interface detaches. Tidy up of
872     code for SetActive and Attach methods including password hiding.
873    
874     38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
875     and used to determine the auth method and protocol used for the connection.
876    
877     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
878     a Create Database Statement generated by IBX.
879    
880     40. All IBServices now have an additional published property "PortNo". This may
881     be set to a non-standard port number when necessary. If zero then the default
882     port number is used.
883    
884     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
885     and not just the mouse.
886    
887     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
888    
889     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
890     image index and selected image index for each node to be set from a database field.
891    
892     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
893     then database schema includes grants to all users. If not present then the
894     only user grants included are those to User PUBLIC.
895    
896     45. TIBTreeView: performance improvement. When expanding include both expanded node
897     and child nodes in dataset.
898    
899    
900     IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
901    
902     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
903     changes.
904    
905     2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
906     Bug could result in truncated multi-byte character set values.
907    
908     3. Changes consequential on moving fbintf character set utility functions from
909     IFirebirdAPI to IAttachment.
910    
911     4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
912    
913     5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
914     results in autocomplete ignoring prefix text.
915    
916     6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
917     entering a new name into the text box.
918    
919     7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
920     Firebird rather than recomputing it.
921    
922     8. Property Editor positioning tidy up: All IBX Property editors should now be
923     screen centre. Previously some were "poDesigned" which may be inappropriate
924     for multi monitor desktops.
925    
926     10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
927    
928     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
929     a transaction and always reset the object.
930    
931     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
932    
933     13. TIBXScript: Allow for override of database filename in Create Database statements.
934    
935     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
936     to a gbak format archive.
937    
938     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
939    
940     16. IBLocaldb: Drop database if error creating an empty database.
941    
942     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
943     unless selected node not in current dataset.
944    
945     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
946     to TIBCustomService, and IBlocalDB code tidy up.
947    
948     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
949     behaviour due to uninitialised variable.
950    
951     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
952     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
953    
954     21. IBSQL: When Database changed ensure that all resources are freed.
955    
956     22. IBCustomDataset: When database changed ensure that queries an unprepared.
957    
958     23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
959     * Line Wrap on SQL Token boundaries (on user command)
960     * auto-complete table names in drop down list of table names
961     * Double click on tablename or field name adds to SQL text
962    
963     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
964    
965     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
966     TVariantArray. Seems to avoid memory corruption in Windows (probably a
967     workaround for a problem in fpc 3.0.4 win64).
968    
969     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
970    
971     27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
972    
973     IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
974    
975     1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
976     include remote system name.
977    
978     2. TIBExtract: No longer include comment header and COMMIT statement for empty
979     tables when data included in output.
980    
981     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
982     and timing information to be written to stdout. This may be used to locate
983     performance bottlenecks.
984    
985     4. SQLParser: only call "OnChanging" event handler when value is different.
986    
987     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
988    
989     6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
990     that BindFields is called when the query is next activated. Avoids FieldName
991     not found error.
992    
993     7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
994     purpose and allows the programmer to define any action they want for Update, Insert
995     or Delete. This may be complex SQL (similar to a Trigger), application specific
996     filtering of updates, or use of statements such as Grant or Revoke instead of
997     normal DML. See User Manual for more information.
998    
999     IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1000    
1001     1. TIBEvents: Fix uninitialised variable that could result in lost events.
1002    
1003     2. TIBExtract: Added support for FB3 "USAGE" privilege.
1004    
1005     3. TIBExtract: data formatted as Charset set "octets" is now output using
1006     hexadecimal notation.
1007    
1008     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
1009     using a simple XML format.
1010    
1011     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
1012     grants to these objects.
1013    
1014     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
1015     dependency problems restoring complex databases.
1016    
1017     7. TIBXScript: This component has been restructured to allow for the processing of
1018     embedded XML in INSERT statements and to support interactive sources in addition
1019     to non-interactive data sources such as files.
1020    
1021     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1022    
1023     9. TIBXScript: ISQL compatiable Set statements are now supported:
1024     SET SQL DIALECT
1025     SET TERM
1026     SET AUTODDL
1027     SET BAIL
1028     SET ECHO
1029     SET COUNT
1030     SET STATS
1031     SET NAMES <character set>
1032    
1033     10. IBVersion unit added to hold current IBX Version Number information.
1034    
1035     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1036     and domain definitions.
1037    
1038     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1039     fully supported.
1040    
1041     13. TIBExtract: when a database dump includes data, the generator values are now also set.
1042    
1043     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1044    
1045     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1046    
1047     See also doc/IBX4LazarusGuide.pdf for important information on
1048     upgrading to IBX2.
1049    
1050     1. Size property of TIBStringField is now the width in characters of the field
1051     and not the byte length. This applies only to multi-byte character sets such
1052     as UTF8. The original approach aligned with TStringField. However, the TStringField
1053     code is not recognised as a bug and hence this change to align the behaviour.
1054     The TStringField change is expected in fpc 3.2.0.
1055    
1056     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1057     true (default) then Size property value saved in the lfm is ignored. Size is
1058     always set from the dynamic information read from the database. It is unclear
1059     why anyone would want to override this and set Size to false.
1060    
1061     3. ibxscript: should now handle correctly a Case..End statement within a procedure
1062     block.
1063    
1064     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1065     exist when an attempt is made to connect to it (run time only) then an attempt
1066     is made to create the database.
1067    
1068     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1069     has been successfully created as a result of a call to CreateDatabase or when
1070     creating a database after it was found not to exist.
1071    
1072     6. DBControlGrid: a race condition could result in the wrong row image being
1073     written to the cache. This has been avoided by a trip round the message
1074     loop before rendering the row image.
1075    
1076     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
1077     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1078     known to risk corrupt rendering of row images when the control is first
1079     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1080     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1081    
1082     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1083     a TDateEdit control located on an editor panel.
1084    
1085     9. TIBExtract: brought up-to-date plus many bug fixes.
1086    
1087     10. DBControlGrid: Removed memory leak when updating rows.
1088    
1089     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
1090    
1091     IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1092    
1093     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1094     when target codepage is CP_NONE. This is a workaround for
1095     http://bugs.freepascal.org/view.php?id=30622.
1096    
1097     2. DBLog option removed from TIBStatisticalService - not supported by server
1098     since Firebird 1.5.
1099    
1100     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1101     similar.
1102    
1103     4. IBCodePage: updated mapping between codepages and character id.
1104    
1105     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1106     Firebird. Character sets with a char width of two are not UTF16.
1107    
1108     6. Strings received from the database are now always transliterated into UTF8
1109     regardless of the database character set or connection character set. This
1110     is for compatibility with the LCL.
1111    
1112     IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1113    
1114     1. IBBlob: Defer reading of blob until read method called. This avoids having to
1115     read in an entire blob just to get the size of the blob. General performance
1116     improvement when opening datasets containing blobs.
1117    
1118     2. Clearing a Blob now sets the corresponding field's modified flag.
1119    
1120     3. IBLookupCombo: When not performing auto-complete, original query sort order
1121     is now used.
1122    
1123     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1124     determined.
1125    
1126     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1127    
1128     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1129     lazarus 1.6.0
1130    
1131     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1132     compilation error.
1133    
1134     IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1135    
1136     1. No character set specified for connection: when a text blob is retrieved, the
1137     character set is determined by looking up the native character set using then
1138     Firebird API. Otherwise a text mode blob is assumed to have the same character
1139     set as the connection.
1140    
1141     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1142     for Login Dialog returing a change to the database path.
1143    
1144     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1145     to be changed from that given in the TIBDatabase/TIBServer component and for the
1146     entered value to be saved on a project specific basis (design time only).
1147    
1148     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1149     column fieldname. If they are the same then it is acts as a look up for the KeyValue
1150     Otherwise, it sets the column text to the selected ListField Value.
1151    
1152     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1153     column width.
1154    
1155     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1156     and a case insensitive search is requested.
1157    
1158     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1159     or column ListSource.
1160    
1161     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1162     unprepare) when closing and the text has not changed.
1163    
1164     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1165     Less likely to cause a cursor re-use error on Windows.
1166    
1167     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1168     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1169    
1170     11. TIBTreeView: Guard against nil destination on record changed
1171    
1172     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1173     string type with the code page set to reflect the returned field encoding after
1174     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1175     earlier versions.
1176    
1177     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1178     will now result in transliteration to the code page specified for the Firebird driver
1179     if the assigned string has a different code page. FPC 3.0.0 onwards only.
1180    
1181     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1182     is ignored and the lc_ctype value, when the database is opened, is set to align with
1183     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1184     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1185     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1186     the GETACP is used to determine the Windows code page.
1187    
1188     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1189     name used as the lc_ctype when the database was opened. Only valid while the
1190     Database is connected.
1191    
1192     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1193     id that corresponds to the DefaultCharSetName.
1194    
1195     IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1196    
1197     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1198     path is given and database attach fails due to access permission issues on the
1199     temp directory or security database, then the attach is retried with "localhost:"
1200     prefixing the databasename. This should avoid problems when the database has to
1201     be accessed by a local (e.g. classic) server and libfbembed is used.
1202    
1203     2. Windows: revised search order for Firebird DLL:
1204     i. The Firebird Embedded Server in the application Directory.
1205     ii. If the FIREBIRD environment variable is set then the directory this
1206     points to is searched for the FB Client DLL and then then underlying
1207     "bin" directory.
1208     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1209     is used to locate the Firebird installation directory and the underlying
1210     "bin" directory is searched for the FB Client DLL.
1211     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1212     are searched for the FB Client DLL.
1213     v. The PATH Environment variable is used to search for the FB Client DLL.
1214     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1215    
1216     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1217     See doc/readme.scriptengine and example applications.
1218    
1219     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1220     simplify the use of the embedded firebird server on both Linux and Windows platforms.
1221     See dpc/readme.localdatabase and example applications.
1222    
1223     5. IBDynamicGrid: Reordering on column header click should now also work for
1224     dynamic columns.
1225    
1226     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1227     between incrementing/decrementing the lock count and signalling the event.
1228    
1229     IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1230    
1231     1.3.2 was never formally released and only made available as beta copies.
1232    
1233     1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1234    
1235     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1236    
1237     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1238    
1239     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1240     i.e. when it is a calculated field
1241    
1242     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1243     This problem was due to a race condition between recalculating row heights and
1244     determining which row was selected by the mouse click. The row height calculation
1245     is now deferred by an extra trip round the message loop allowing the row to
1246     be always calculated on the current grid layout rather than risking it being
1247     calculated on the grid layout after the expanded row has been shrunk.
1248    
1249     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1250     Windows.
1251    
1252     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1253     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1254     to be determined at runtime. See doc/readme.charactersets.html.
1255    
1256     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1257     TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1258    
1259     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1260     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1261     1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1262    
1263     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1264     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1265     implies no truncation.
1266    
1267     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1268    
1269     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1270     (avoids "Not in Edit Mode" error).
1271    
1272     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1273    
1274     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1275     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1276    
1277     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1278    
1279     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1280    
1281     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1282    
1283     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1284    
1285     IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1286    
1287     1. OnCloseUp Event Handler added to TDBLookupProperties
1288    
1289     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1290     problem with row size when exception is called.
1291    
1292     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1293    
1294     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1295     in a TCustomComboBox and ignores return key if in a TCustomMemo
1296    
1297     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1298     keyed in i.e. when autocomplete not performed
1299    
1300     6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1301     console mode applications with all LCL required functions (builtin dialogs and
1302     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1303     not included in your project, IBX should compile and link with a console mode program.
1304     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1305     console mode application or the IDE will automatically assume that your
1306     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1307    
1308     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1309     to use the built in dialogs and cursor management. IBDialogs is
1310     included by default if "ibexpress" is in your project source's "uses" clause.
1311     This should be the case for all projects created through the IDE. This is why
1312     you do not want to add the ibexpress package to console mode applications. The
1313     ibexpressconsolemode package has been created to allow console mode programs
1314     to avoid adding LCL dependencies when using IBX, while still having the
1315     unit search paths set up correctly.
1316    
1317     Existing users should check to ensure that the "ibexpress" unit is included in
1318     each project's source file (*.lpr).
1319    
1320     You may find that in order for the IDE to recognise that ibexpressconsolemode
1321     exists, you have to first open the package in the IDE and then close it. This
1322     adds it to the most recently accessed packages list. To make it permanently
1323     available, add the package name to lazarus' staticpackages.inc file.
1324    
1325     Thanks to Julio Jiménez for suggesting support of console mode.
1326    
1327     7. SQL Parser can now accept quoted strings that include new lines
1328    
1329     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1330     of text on start of edit. This is particularly useful when tabbing to a
1331     column and then inserting text.
1332    
1333     9. New Examples provided for IB Services and ISQLMonitor.
1334    
1335     10. Fix error when writing to blob streams that recorded only the last buffer
1336     write in the blob stream. In most cases, this did not cause a problem as the
1337     IB Blob Stream is written in a single write. However, with the TDBImage, write
1338     of a graphic type prefix was lost which caused a problem when the image could
1339     not be automatically recognised.
1340    
1341     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1342     already open" errors due to random numbers used for the cursor name being identical.
1343    
1344     12. IBTable: corrected error that could result in an "Index out of bounds" error
1345     when opening the table and the Primary Key is the last or only column in the
1346     table. Thanks to Rick Hoover for the fix.
1347    
1348     13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1349     of "UTF-8", and update list of available database character sets. Existing
1350     users should check the current lc_ctype setting in their applications.
1351    
1352     IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1353    
1354     1. Firebird Services: avoid List Index error when opening a service with an
1355     empty Params property.
1356    
1357     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1358     Link now set up in Loaded method - avoids occasional failure to apply
1359     SQL markup on initial open.
1360    
1361     3. "Employees" example performance improvements when scrolling.
1362    
1363     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1364     TFrame. Force recaching of selected frame to avoid GTK race (results in a
1365     random image cached).
1366    
1367     5. DBControlGrid: Should now react to changes in panel height at run time.
1368    
1369     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1370     even when further rows exist.
1371    
1372     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1373     always be derived from panel height and setting this property can cause confusion.
1374     Note for existing projects: to avoid a missing property error at run time,
1375     each form using the DBControlGrid must be opened, updated and saved in the IDE
1376     in order to remove the property value from the lfm.
1377    
1378    
1379     IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1380    
1381     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1382     call Prepare before setting parameter values.
1383    
1384     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1385    
1386     3. Code tidyup and more robust handling of dsql information result vector.
1387    
1388     4. Support for centralised handling of transaction status changes. TIBTransaction
1389     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1390     and "AfterExecQuery". The first three are called after the same event is called
1391     for an IBCustomDataSet descendent using the Transaction. The fourth is called
1392     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1393     enable monitoring of transaction status changes for a given transaction to be
1394     handled in a single place. For example, when a change to the dataset occurs
1395     an indicator can be set that shows the user that in order to save changes,
1396     the transaction should be committed. Rather than doing this per dataset, this
1397     can now be done per transaction.
1398    
1399     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1400     the dataset is scrolled. However, any changes to the current row are, by default,
1401     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1402     have a new property "DataSetCloseAction" that adds automatic posting of changes
1403     on dataset close. If this property is set to dcDiscardChanges (default) then the
1404     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1405     then IBX will attempt to post any unsaved changes before the dataset is closed
1406     (and after the BeforeClose event handler is called). The exception is when the
1407     dataset is being closed as a result of a transaction rollback. In this case,
1408     no action is taken and any unsaved changes are discarded. This avoids both
1409     unnecessary overhead and the risk that a validation error may occur in the Post
1410     raising an exception and thereby preventing a rollback.
1411    
1412     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1413     In earlier versions, the Display Width was set to the maximum byte width rather than the character
1414     width. Display Widths are now corrected by dividing by the max byte width per character.
1415     For UTF8 character sets, the byte width is four and hence the Display Width will be
1416     the byte width divided by 4. The byte width of each character set is determined
1417     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1418     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1419    
1420     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1421    
1422     8. IBLookupComboEditBox: List should now always be restored to full list when the
1423     control loses focus. Default Key press default interval reduced to 200ms.
1424    
1425     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1426     when dataset rows are less than visible rows.
1427    
1428     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1429     does not exist or DataSet is empty. More responsive on dataset open. New event
1430     OnRestorePosition. Column sort disabled if no header row.
1431    
1432     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1433     while dataset state is dsInsert. Avoids posting errors.
1434    
1435     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1436     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1437    
1438     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1439    
1440     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1441     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1442     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1443     always "posts" the current record regardless or whether or not it may be more appropriate
1444     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1445     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1446     as the first action of the "Post" method and allows the handler to convert the Post
1447     into a Cancel if that is the appropriate action on moving to a different row. This is
1448     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1449     raised here, but it may still be more appropriate to validate a post and signal
1450     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1451    
1452     15. On Unix derived systems, the Firebird library name can now be given as a colon
1453     separated list. Each library name on the list is tried in turn, in left to right
1454     order with the first found being used as the firebird library. By default, on Linux,
1455     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1456     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1457    
1458     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1459     then it will still attempt to access the database via the Firebird Server and will
1460     require a username and password. If only the pathname is given, then the username
1461     and password should be omitted and the unix file permissions are used to grant
1462     access.
1463    
1464     IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1465    
1466     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1467     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1468     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1469     corresponds to a row of the linked DataSource. Any data aware control on the
1470     replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1471    
1472     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1473     When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1474     takes place during database access. This may be useful when there are performance issues with
1475     the change of cursor. Setting the property to false suppresses the change of cursor.
1476    
1477     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1478     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1479     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1480     making all changes permanent immediately rather than when the transaction is explicitly
1481     committed.
1482    
1483     4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1484     using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1485    
1486     IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1487    
1488     Development version only.
1489    
1490     IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1491    
1492     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1493     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1494     "Where" and "Having" clauses to implement user specified filters of arbitrary
1495     complexity.
1496    
1497     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1498     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1499     These are:
1500    
1501     - TIBLookupComboEditBox
1502     - TIBDynamicGrid
1503     - TIBTreeview
1504    
1505     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1506     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1507     to revise the available list and restrict it to items that are prefixed by the
1508     typed text (either case sensitive or case insensitive). Autoinsert allows a
1509     newly typed entry to be added to the list dataset and included in the available
1510     list items.
1511    
1512     TIBDynamicGrid is a TDBGrid descendent that provides for:
1513     - automatic resizing of selected columns to fill the available row length
1514     - automatic positioning and sizing of a "totals" control, typically at the
1515     column footer, on a per column basis.
1516     - DataSet resorting on header row click, sorting the dataset by the selected column.
1517     A second click on the same header cell reversed the sort order.
1518     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1519     is automatically expanded and a panel superimposed on it. The panel can have any
1520     number of child controls, typically data aware controls with the same datasource
1521     as the grid allowing for editing of additional fields and more complex editors.
1522     - Reselection of the same row following resorting.
1523     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1524     Its properties are specified on a per column basis and allows for one or more
1525     columns to have their values selected from a list provided by a dataset.
1526     Autocomplete and autoinsert are also available. The existing picklist editor
1527     is unaffected by the extension.
1528    
1529     TIBTreeView is a data aware TCustomTreeView.
1530    
1531     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1532     zero scale will no longer return an error. An Int64 will be returned instead.
1533    
1534     4. TIBTransaction now has events for Before and After Transaction End and a new function
1535     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1536    
1537     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1538     repeated multiple times.
1539    
1540     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1541     check used to get in the way of using Stored Procedures, and "Update or Insert"
1542     statements.
1543    
1544     7. Insert, Modify and Delete property Editors now support Query Generation from
1545     Stored Procedures.
1546    
1547     8. Three new examples illustrate the use of the new IB Controls
1548    
1549    
1550     IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1551    
1552     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1553     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1554     Gabor Boros for reporting this problem and for testing the improvements).
1555    
1556     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1557     See readme.field+param.names in the doc folder.
1558    
1559     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1560     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1561    
1562     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1563    
1564     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1565     actions.
1566    
1567     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1568     thanks to Yuriy Kopnin for pointing this out).
1569    
1570     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1571    
1572     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1573     for both fields and parameter setting.
1574    
1575     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1576     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1577    
1578     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1579     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1580    
1581     11. TIBTable now has a property editor for "MasterFields"
1582    
1583     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1584     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1585    
1586     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1587     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1596     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1597     it is null. This allows for alternative user defined setting of the generator
1598    
1599     Many thanks to Julio Jiménez for this fix
1600    
1601     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1602     and suggests that the user may have forgotten to install it.

1606     1. Conditional compilation used to limit registration of TIntegerField to
1607     Lazarus versions less than 1.1
1608    
1609     2. When a database connection is created, character set is now by default set
1610     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1611     1250 to 1254.

1620    
1621     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1622     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1623    
1624     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1625     package is changed to do this (which it should do).
1626

1628    
1629     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1630    
1631     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1632    
1633     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1634    
1635     4. Property editors should now correctly resize.
1636    
1637     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1638     (restored original functionality)
1639    
1640     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1641     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
