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 427 3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
10     issues with left over pointers to invalid internal buffers.
11    
12 tony 429 4. TIBCustomDataset.PrimaryKeys when used in InternalRefresh. when more than one
13     primary key is used by the dataset then the list of primary keys is now
14     properly separated by a ';'.

17    
18     1. Update to calls to EInterbaseError to add default code page. Consequential
19     on change to fbintf.
20    
21     2. Update some examples to replace test for null date with the NullDate constant
22     instead of zero. This is because Laz 3.0 changes the value of NullDate.
23

25 tony 416
26     1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
27 tony 418 with later versions of fpc - later than 3.2.2.
28 tony 416
29 tony 418 2. IBUpdateSQL. update internal queries if parent dataset database changed.
30    
31     3. IBUpdateSQL: Do not prepare an empty internal query.
32    
33 tony 419 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
34 tony 418
35 tony 419 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
36    
37 tony 412 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
38

43    
44     3. ibxscript: When parsing a store procedure or function with a variable name
45     enclosed in doublequotes, the double quotes are no longer removed.
46    
47 tony 410 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
48 tony 407
49 tony 410 NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
50     AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
51     BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
52     ISSUES TO support@mwasoftware.co.uk
53    
54     1. Complete rewrite of internal buffer management in order to improve performance
55     and maintainability. Highlights:
56    
57     * Extending the size of the buffer pool no longer has to copy the entire record
58     cache. Instead, a new extent is simply added to the buffer pool.
59     * A memory to memory copy of each display buffer now is avoided when scolling the
60     dataset.
61     * A separate set of buffers is now used for calculated fields. This avoids
62     having to keep copies of calculated field values in the buffer cache.
63     * Compact bitmaps are used to record null status and need to refresh in each
64     buffer.
65     * Display buffer type changed from PChar to TRecordBuffer in line with change of
66     buffer type in FCL-DB.
67    
68     2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
69     to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
70    
71     3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
72     If either or both of these flags are set at design time (using the fields editor)
73     then this forces a row refresh on respectively insert or update, or both, when the
74     corresponding field is not present in an SQL RETURNING clause.
75    
76     4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
77     maintainability and readability and to add identification of primary key fields.
78    
79     5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
80     as a refresh of the current row. However, this is different behaviour to that described
81     in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
82     the dataset from the underlying database, and attempts to reposition the cursor on
83     the same record as it was". IBX now complies with the FPC definition of Refresh.
84    
85     6. A progammatic Row Refresh should no longer be required.
86     Use Insert/Update... returning to refresh any fields that may change following an
87     insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
88     on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
89     for the field at Design Time to force a row refresh if not in the returning clause.
90    
91     7. It should now be possible to insert a row into an empty unidirectional dataset.
92    
93     8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
94     This gives the number of buffers in the initial block for the buffer pool in
95     bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
96     in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
97     for small datasets.
98

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

1588     11. TIBTable now has a property editor for "MasterFields"
1589    
1590     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1591     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1592    
1593     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1594     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1603     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1604     it is null. This allows for alternative user defined setting of the generator
1605    
1606     Many thanks to Julio Jiménez for this fix
1607    
1608     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1609     and suggests that the user may have forgotten to install it.

1613     1. Conditional compilation used to limit registration of TIntegerField to
1614     Lazarus versions less than 1.1
1615    
1616     2. When a database connection is created, character set is now by default set
1617     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1618     1250 to 1254.

1627    
1628     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1629     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1630    
1631     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1632     package is changed to do this (which it should do).
1633

1635    
1636     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1637    
1638     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1639    
1640     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1641    
1642     4. Property editors should now correctly resize.
1643    
1644     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1645     (restored original functionality)
1646    
1647     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1648     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
