1 IBX Change Log version (2.3-5 Build 12341) Mon, 24 Aug 2020 10:23:35 +0100
2
3 1. TIBStringField: when a string value is read from a dataset buffer, if the
4 number of UTF8 characters exceeds the string size then string is truncated
5 to the maximum string size. This is usually a problem with fixed width columns
6 right padded with white space.
7
8 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 If SQLFiltered is set then when a dataset is opened, each line in the
10 SQLFilterParams property is assumed to be a SQL condition clause and
11 ANDed into the Where clause of the SQL Select statement provided as a
12 dataset property. Each such SQL condition thus acts as an additional filter
13 on the dataset. (Not yet tested)
14
15 3. The Filtered property inherited from TDataset is no longer used for SQL (server
16 side filters).
17
18 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 text matches complete entry.
20
21 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 dataset are active (avoids risk of access violation if master is inactive)
23
24 6. TIBEvents: Registered property can now be set at design time even if database not open
25
26 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 This should prevent "spillover" of events between sessions.
28
29 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 This should ensure that the internal buffer is set up correctly and avoids
31 a duplicate initial row.
32
33 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 That is, the DataSize should be the field size * character set width. The
35 value returned by DataSize is now the same as the Dataset buffer size reserved
36 for the field.
37
38 10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes.
39
40 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 and vice-versa. This may result in an exception being raised (correctly) for
42 older programs when using dataset fields added to a form and the database has been
43 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 In such cases, the field needs to be deleted in the IDE fields editor and then
45 added back in.
46
47 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
48 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
49 is cancelled.
50
51 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
52
53 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
54 not SQL Identifiers are now supported.
55
56 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
57 passed to the Firebird engine for execution.
58
59 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
60 is made to scroll back.
61
62 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
63
64 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
65 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
66
67 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
68 validated. If no match is found in the list of field names and the database has
69 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
70 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
71
72 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
73 with fpc 3.2.
74
75 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
76
77
78 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
79 and is used to override the default settings in the client side "firebird.conf" This
80 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
81 Each line of the string list should be a setting in the same format as "firebird.conf".
82 For example "WireCompression = true" in order to request wire compression on the client side.
83
84 Note: explicit settings in the client side "firebird.conf" appear to take precedence
85 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
86 also require a compatible setting in the server side "firebird.conf". For example
87 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
88 compression to be used.
89
90 Whether or not WireCompression or WireCrypt are in use can be checked using the information
91 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
92 ibx/examples/dbinfo for examples of how to display this information.
93
94 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
95 is a "convenience" property. If set the "WireCompression=true" is added to the
96 ConfigOverrides. If unchecked then this setting is removed.
97
98 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
99 not "INT64".
100
101 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
102 These are:
103 property TimestampFormat: string;
104 property DateFormat: string;
105 property TimeFormat: string;
106
107 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
108 DATETIME and TIME. The format strings use the standard FPC date/time format
109 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
110
111 If any of the above properties are set to an empty string, then the locale default
112 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
113 locale default is extended by appending '.zzz' to include milliseconds.
114
115 TIBCSVDataOut by default sets these properties to the empty string, while the other
116 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
117
118 5. New published property for TIBCSVDataOut:
119 property QuoteStrings: boolean (default true)
120
121 If false then strings are unquoted, otherwise, the QuoteChar property value is
122 used to delimit each and every string in the output.
123
124 6. New published properties for TIBCSVDataOut:
125 property FieldSeparator: string;
126 property HeaderSeparator: string;
127
128 Respectively, these provide the separator character(s) used to separate fields
129 in data and header rows. Both default to ','.
130
131 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
132 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
133 property OnFormatTextString;
134
135 This event handler can be used to process text strings before they are included
136 in the output e.g. to replace unprintable characters with alternative strings.
137 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
138
139 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
140 Uses "FindParam" if in order to find out if a parameter with a given name exists
141 and without raising and exception if it does not.
142
143 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
144 consistency with SQL queries.
145
146 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
147 When true, SQL statement parameter names are parsed case sensitive. Note for
148 TIBDataSet only applies to Select query.
149
150 11. IBEvents: removing a TIBEvent component from a form should no longer result in
151 an IDE exception.
152
153 12. LocalDBSupport: initial database creation should now work correctly
154 when the schema source is an sql file.
155
156 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
157 when defined, this handler will be called by the internal TIBXScript during
158 initial database creation when the schema source is an sql file and may be used
159 to provide a visual indication of progress in console mode.
160
161 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
162 to true while a new local database is being created and its schema populated.
163 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
164 when the database is disconnected/connected during the create DB procedure.
165
166 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
167 are now always ignored and replaced by the user name and password provided as
168 the login parameters for the TIBDatabase referenced from the TIBXScript. The
169 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
170 completely ignored if this property is true.
171
172 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
173 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
174 ImageIndex and SelectImageIndex values on AddNode.
175
176 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
177 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
178 the same database connection.
179
180 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
181 if provided, this should be an conditional SQL expression suitable for
182 including in an SQL Select statement "where" clause. If non-empty and the
183 "Filtered" property is true then the SQL expression provided as the value of
184 the "Filter" property is "ANDed" with any existing condition statement
185 in the SQL statement's "Where" clause.
186
187 If the "Filter" property is set at run time, the "Filtered" property is true
188 and the dataset is already open, then the dataset is closed and re-opened automatically.
189
190 The "Filter" condition may include IBX style parameters. In which case, their
191 value must be set by the dataset's "OnBeforeOpen" event handler.
192
193 This is a public property for TIBDataSet and TIBQuery query and intended for
194 use at run time.
195
196 Note: The property is a published property of TIBTable. The TIBTable functionality
197 is unaffected by this change.
198
199 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
200
201 1. Remove need to check for IsMultiThread by providing access to GUI timers via
202 IBGUIInterface. Note: master/detail delay timer does not apply to console
203 mode apps.
204
205 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
206 statement. This avoids problems if "Execute Block" is used as the Query.
207
208 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
209 internal SQL tokeniser routines.
210
211 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
212 as a select statement, with or without CTEs.
213
214 5. IBSQLParser: parser now recognises the "ROWS" clause.
215
216 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
217 internal SQL tokeniser routines.
218
219 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
220 being raised for valid set statements processed by a data formatter.
221
222 8. New published property for TIBDatabase and TIBXServicesConnection. This is
223 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
224 the path of the Firebird Library used by the database/services connection.
225
226 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
227 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
228 services connection.
229
230 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
231 or param name is not a valid SQL identifier.
232
233 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
234 view of whether the text box should be editable when no DataSource is specified.
235 TIBLookupComboEditBox has been updated to workaround this problem. As long as
236 ReadOnly is false, the text box is editable when no DataSource is specified.
237
238 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
239 the FBLIB environment variable. If you do not want to permit this then you
240 must modify the Register procedure in the design/IBDBReg.pas unit to remove
241 this setting.
242
243 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
244
245 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
246 Utf8EscapeControlChars
247
248 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
249
250 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
251 all previous copies of the IBX source code tree before installing this release.
252
253 The IBX packages used by most users have not changed, with one exception. The
254 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
255 to use the IBServices unit in your applications, please add the iblegacyServices
256 to the list of dependencies. To do this, open the Project Inspector and select
257 Add->New Requirement and select "ibLegacyServices" from the list of available
258 packages.
259
260 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
261 the IBServices unit providing what is intended to be a clearer and easier to
262 use set of IB Services components. See Chapter 10 of the IBX User Guide for
263 more information and the guide to "Firebird Service Management Using IBX".
264 As indicated above, the legacy services components are still available and
265 provided in a separate package. There is no need to update working applications
266 using the older versions except for an additional package dependency.
267
268 2. The IBX packages and source code tree have been re-organised in an attempt to
269 finally get rid of the "duplicate ppu" warnings. This re-organisation should
270 not affect existing users. Section 2.3 of the IBX User Guide describes the
271 new set of IBX packages.
272
273 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
274 updated to use the new Services API components.
275
276 4. The iblocal package has been updated to use the new Services API components.
277
278 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
279 TIBXSecurityService. It had been wrongly classified in the previous version
280 as a per database configuration item. It is global to a server and hence
281 correctly positioned as part of the Security Package. In the DBAdmin example,
282 the setting has moved to the mappings page.
283
284 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
285 are ignored.
286
287 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
288 closed before the database is dropped. Before and After Disconnect event handlers
289 are also fired.
290
291 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
292 is started and not just the first time.
293
294 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
295 depenendency with comp type.
296
297 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
298
299 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
300 then this is recognised and not ignored.
301
302 12. TIBDataSet, TIBQuery, TIBTable: additions:
303 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
304 function GetPerfStatistics(var stats: TPerfCounters): boolean;
305 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
306
307 GetRowsAffected returns the affected row counts from the last insert/update/delete
308 if EnableStatistics = true then GetPerfStatistics returns the current stats
309 counters for the select query. Note: stats accumulate after each fetch from
310 the database. To get total query cost after open, call the "Last" method
311 and then GetPerfStatistics.
312
313 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
314
315 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
316 in parenthesises.
317
318 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
319 SQL identifiers are always delimited by double quotes. If false, then they are
320 only delimited if the identifier is a reserved word, contains lower case or special
321 characters. Set this property to true to retain previous behaviour.
322
323 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
324 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
325
326 16. TIBDataSet, TIBQuery, TIBTable: addition:
327 property MasterDetailDelay: integer {defaults to zero}
328
329 When non-zero and the dataset is a detail table referencing a master table
330 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
331 then a synchronisation delay is added (in milliseconds) between the master
332 row changing and the detail dataset being re-opened. If the master dataset
333 is scrolled before the delay expires then the delay is reset. This can be used
334 to avoid performance overheads when scrolling through a large master dataset.
335
336 Note: uses fptimer and hence requires a thread manager. Under Linux the
337 chreads unit must be included in your project. TTimer is not used in order
338 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
339
340 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
341 with Extract Option eoDatabase.
342
343 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
344 When a deLayoutChanged event is reported on the ListSource dataset, the
345 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
346 relationship with the control's datasource (master).
347
348 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
349
350 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
351 stubs. Pedantic fix really, as procedures output in dependency order anyway.
352
353 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
354 DDL (Firebird 3 and later only).
355
356 22. TIBLookupComboBox Autocomplete Fixes:
357 i. Only appended text is now selected after autocomplete.
358 ii. Uppercase keys no longer ignored for autocomplete.
359 iii. Retain Prefix case is now honoured correctly.
360 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
361 before autocomplete performed. i.e. behaviour now the same as when
362 no DataSource assigned.
363
364 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
365 between SQL statements.
366
367 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
368 ObjectNames are converted to upper case before matching against metadata object
369 names, unless the objectname is delimited by double quotes, in which case, the
370 double quotes are removed and the remaining string is used (unmodified) to match
371 against the metadata object name.
372
373 If true then the ObjectName is used as is without modification and matched
374 against the metadata object name. No attempt is made to remove double quotes.
375
376 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
377 with eoTrigger, these extract types can be used to select only Database Triggers,
378 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
379
380 26. TIBXScript: If an exception occurs during the processing of a statement, the
381 statement separate character is now reset to the default (';').
382
383 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
384
385 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
386 a commit or reconnect statement and instead activated only when next SQL statement
387 is executed.
388
389 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
390
391 30. TIBXScript: case insensitive regex now used when matching statements instead of
392 converting statement to upper case.
393
394 31. TIBExtract: metadata comments now supported. New published property
395 IncludeMetaDataComments (default true). If true then metadata comments included
396 in extracted DDL. New Extract Object member eoComments. This may be used with
397 ExtractObject method to list all metadata comments.
398
399 32. TIBExtract: ListObjectNames method added.
400
401 33. Updated Database component editor to support additional connection string
402 types.
403
404 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
405
406 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
407 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
408 RELEASE.
409
410 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
411
412 1. IBExtract: Identity columns - add additional check for null column for generator name.
413
414 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
415 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
416 information). However, this is also a very useful mechanism for returning updated computed by
417 column values. Values returned as a result of executing an Insert or Update statement
418 replace existing values in the current row for each corresponding column.
419
420 Previously, if a dataset's select query included read only (computed by) fields then
421 an automatic row refresh was performed after an insert or update query had been processed,
422 irrespective of the setting of the "ForcedUpdates" property. This has changed such
423 that an automatic refresh is no longer performed if an insert or update query contains
424 a returning clause that updates one or more fields on the current row. A full row
425 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
426 field values and the select query contains read only fields. Use of Insert/update
427 returning should be significantly more efficient than executing a refresh query.
428
429 This behaviour change is intended to be backwards compatible and there should be no need to change
430 existing programs, other than to improve performance by using the new capability.
431
432 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
433 they are called when the dataset row is being deleted, there is no value in
434 updating the current record from the query result. Instead, a new event handler
435 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
436 an OnDeleteReturning event handler is provided then it is called with the IResults returned
437 by the query. The event handler can then interrogate the query results and
438 perform whatever action is necessary. For example to confirm, to the user,
439 the deletion of a row with the returned values.
440
441 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
442 any Computed By or Identity Columns. The IBTables example has been updated to
443 illustrate the computation of the employee Full Name on update.
444
445 5. TIBTable: The GeneratorField property is now published.
446
447 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
448 When InsertSQL is generated, the Identity columns are not included in the list of values to
449 be inserted. A RETURNING clause is added to the insert statement to return the value of
450 each Identity column after the insert is executed.
451
452 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
453 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
454 Insert..Returning clause.
455
456 8. TIBGenerator: small performance improvement by not preparing query each time
457 a new value is generated.
458
459 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
460
461 10. Property editors will now sync table name to a System Table when "Include System
462 Tables" is selected and the query is for a System Table.
463
464 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
465 values are no longer converted to milliseconds from TDateTime and then back again
466 to TDateTime (the conversion to milliseconds is the default TDataset approach).
467
468 12. Property Editors handling of Stored Procedures.
469 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
470 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
471 query).
472 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
473
474 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
475 can be used to select a package. If non-empty, the stored procedure name is
476 expected to be a stored procedure defined in the specified package and the
477 generated SQL will be as required for a stored procedure located in a package.
478
479 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
480 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
481 which a stored procedure can be selected. With no package name selected, non-package
482 stored procedures are listed.
483
484 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
485 for password on reconnect.
486
487 16. TIBDatabase: use IAttachment for connection default character set id, code page
488 and character set name.
489
490 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
491 DB info lookups"
492
493 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
494
495 19. Add a property Editor for TIBUpdate.RefreshSQL.
496
497 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
498 parameters. This stops an exception being raised when the field cannot be
499 located in the record buffer.
500
501 21. Property Editors now automatically include System Tables when opened and when the query table
502 is a System Table.
503
504 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
505 This avoids errors due to a stale SQRB or SRB being used for the next query.
506
507 23. IBServices: Service attach parameters now include "expected_db". This is used to
508 add the SPB item isc_spb_expected_db. This names a database using
509 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
510 database. examples/services re-written to illustrate use of "expected_db".
511
512 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
513 This avoids truncated backups when the server returns a timeout (busy) response.
514
515 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
516
517 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
518 databasenames. These are respectively expanded to the local system's temp directory
519 (including trailing delimiter) or to a prescribed data directory (including
520 trailing delimiter). Under Unix systems the data directory is a hidden directory
521 in the user's home directory. The hidden directory name is either the string returned
522 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
523 Under Windows, the directory is the same as the Data Directory as decribed
524 above but instead prefixed by the User's application data path. These may be
525 used to improve application portability for Personal Databases.
526
527 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
528 this has not worked for a long time and is not useful either. FieldDefs should be
529 managed using the Fields Editor as with any other dataset. To access the fields
530 editor for a TIBTable component, double click on the component. The fields editor
531 is then displayed.
532
533 28. TIBDatabaseInfo: new properties/function
534 * DateDBCreated (returns date/time database created)
535 * TransactionCount (returns no. of active transactions)
536 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
537 * PagesFree (Firebird 3 or later)
538 * PagesUsed (Firebird 3 or later)
539 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
540 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
541
542 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
543
544 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
545
546 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
547 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
548
549 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
550 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
551 firing during backup and restore.
552
553 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
554 for verbose output using the new property "StatisticsRequested".
555 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
556
557 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
558
559 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
560 palette. This uses the online validation feature added in Firebird 2.5. The
561 services's properties enable inclusion/exclusion of tables and indexes using
562 regular expressions. See.
563 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
564
565 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
566 option on a database.
567
568 37. TIBCustomService: Assign method implemented to allow copying of service login
569 context between service API components. "Detach" method now only detaches
570 service when last reference to the service interface detaches. Tidy up of
571 code for SetActive and Attach methods including password hiding.
572
573 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
574 and used to determine the auth method and protocol used for the connection.
575
576 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
577 a Create Database Statement generated by IBX.
578
579 40. All IBServices now have an additional published property "PortNo". This may
580 be set to a non-standard port number when necessary. If zero then the default
581 port number is used.
582
583 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
584 and not just the mouse.
585
586 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
587
588 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
589 image index and selected image index for each node to be set from a database field.
590
591 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
592 then database schema includes grants to all users. If not present then the
593 only user grants included are those to User PUBLIC.
594
595 45. TIBTreeView: performance improvement. When expanding include both expanded node
596 and child nodes in dataset.
597
598
599 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
600
601 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
602 changes.
603
604 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
605 Bug could result in truncated multi-byte character set values.
606
607 3. Changes consequential on moving fbintf character set utility functions from
608 IFirebirdAPI to IAttachment.
609
610 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
611
612 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
613 results in autocomplete ignoring prefix text.
614
615 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
616 entering a new name into the text box.
617
618 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
619 Firebird rather than recomputing it.
620
621 8. Property Editor positioning tidy up: All IBX Property editors should now be
622 screen centre. Previously some were "poDesigned" which may be inappropriate
623 for multi monitor desktops.
624
625 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
626
627 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
628 a transaction and always reset the object.
629
630 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
631
632 13. TIBXScript: Allow for override of database filename in Create Database statements.
633
634 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
635 to a gbak format archive.
636
637 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
638
639 16. IBLocaldb: Drop database if error creating an empty database.
640
641 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
642 unless selected node not in current dataset.
643
644 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
645 to TIBCustomService, and IBlocalDB code tidy up.
646
647 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
648 behaviour due to uninitialised variable.
649
650 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
651 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
652
653 21. IBSQL: When Database changed ensure that all resources are freed.
654
655 22. IBCustomDataset: When database changed ensure that queries an unprepared.
656
657 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
658 * Line Wrap on SQL Token boundaries (on user command)
659 * auto-complete table names in drop down list of table names
660 * Double click on tablename or field name adds to SQL text
661
662 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
663
664 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
665 TVariantArray. Seems to avoid memory corruption in Windows (probably a
666 workaround for a problem in fpc 3.0.4 win64).
667
668 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
669
670 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
671
672 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
673
674 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
675 include remote system name.
676
677 2. TIBExtract: No longer include comment header and COMMIT statement for empty
678 tables when data included in output.
679
680 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
681 and timing information to be written to stdout. This may be used to locate
682 performance bottlenecks.
683
684 4. SQLParser: only call "OnChanging" event handler when value is different.
685
686 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
687
688 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
689 that BindFields is called when the query is next activated. Avoids FieldName
690 not found error.
691
692 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
693 purpose and allows the programmer to define any action they want for Update, Insert
694 or Delete. This may be complex SQL (similar to a Trigger), application specific
695 filtering of updates, or use of statements such as Grant or Revoke instead of
696 normal DML. See User Manual for more information.
697
698 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
699
700 1. TIBEvents: Fix uninitialised variable that could result in lost events.
701
702 2. TIBExtract: Added support for FB3 "USAGE" privilege.
703
704 3. TIBExtract: data formatted as Charset set "octets" is now output using
705 hexadecimal notation.
706
707 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
708 using a simple XML format.
709
710 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
711 grants to these objects.
712
713 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
714 dependency problems restoring complex databases.
715
716 7. TIBXScript: This component has been restructured to allow for the processing of
717 embedded XML in INSERT statements and to support interactive sources in addition
718 to non-interactive data sources such as files.
719
720 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
721
722 9. TIBXScript: ISQL compatiable Set statements are now supported:
723 SET SQL DIALECT
724 SET TERM
725 SET AUTODDL
726 SET BAIL
727 SET ECHO
728 SET COUNT
729 SET STATS
730 SET NAMES <character set>
731
732 10. IBVersion unit added to hold current IBX Version Number information.
733
734 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
735 and domain definitions.
736
737 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
738 fully supported.
739
740 13. TIBExtract: when a database dump includes data, the generator values are now also set.
741
742 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
743
744 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
745
746 See also doc/IBX4LazarusGuide.pdf for important information on
747 upgrading to IBX2.
748
749 1. Size property of TIBStringField is now the width in characters of the field
750 and not the byte length. This applies only to multi-byte character sets such
751 as UTF8. The original approach aligned with TStringField. However, the TStringField
752 code is not recognised as a bug and hence this change to align the behaviour.
753 The TStringField change is expected in fpc 3.2.0.
754
755 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
756 true (default) then Size property value saved in the lfm is ignored. Size is
757 always set from the dynamic information read from the database. It is unclear
758 why anyone would want to override this and set Size to false.
759
760 3. ibxscript: should now handle correctly a Case..End statement within a procedure
761 block.
762
763 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
764 exist when an attempt is made to connect to it (run time only) then an attempt
765 is made to create the database.
766
767 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
768 has been successfully created as a result of a call to CreateDatabase or when
769 creating a database after it was found not to exist.
770
771 6. DBControlGrid: a race condition could result in the wrong row image being
772 written to the cache. This has been avoided by a trip round the message
773 loop before rendering the row image.
774
775 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
776 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
777 known to risk corrupt rendering of row images when the control is first
778 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
779 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
780
781 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
782 a TDateEdit control located on an editor panel.
783
784 9. TIBExtract: brought up-to-date plus many bug fixes.
785
786 10. DBControlGrid: Removed memory leak when updating rows.
787
788 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
789
790 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
791
792 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
793 when target codepage is CP_NONE. This is a workaround for
794 http://bugs.freepascal.org/view.php?id=30622.
795
796 2. DBLog option removed from TIBStatisticalService - not supported by server
797 since Firebird 1.5.
798
799 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
800 similar.
801
802 4. IBCodePage: updated mapping between codepages and character id.
803
804 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
805 Firebird. Character sets with a char width of two are not UTF16.
806
807 6. Strings received from the database are now always transliterated into UTF8
808 regardless of the database character set or connection character set. This
809 is for compatibility with the LCL.
810
811 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
812
813 1. IBBlob: Defer reading of blob until read method called. This avoids having to
814 read in an entire blob just to get the size of the blob. General performance
815 improvement when opening datasets containing blobs.
816
817 2. Clearing a Blob now sets the corresponding field's modified flag.
818
819 3. IBLookupCombo: When not performing auto-complete, original query sort order
820 is now used.
821
822 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
823 determined.
824
825 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
826
827 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
828 lazarus 1.6.0
829
830 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
831 compilation error.
832
833 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
834
835 1. No character set specified for connection: when a text blob is retrieved, the
836 character set is determined by looking up the native character set using then
837 Firebird API. Otherwise a text mode blob is assumed to have the same character
838 set as the connection.
839
840 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
841 for Login Dialog returing a change to the database path.
842
843 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
844 to be changed from that given in the TIBDatabase/TIBServer component and for the
845 entered value to be saved on a project specific basis (design time only).
846
847 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
848 column fieldname. If they are the same then it is acts as a look up for the KeyValue
849 Otherwise, it sets the column text to the selected ListField Value.
850
851 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
852 column width.
853
854 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
855 and a case insensitive search is requested.
856
857 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
858 or column ListSource.
859
860 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
861 unprepare) when closing and the text has not changed.
862
863 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
864 Less likely to cause a cursor re-use error on Windows.
865
866 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
867 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
868
869 11. TIBTreeView: Guard against nil destination on record changed
870
871 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
872 string type with the code page set to reflect the returned field encoding after
873 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
874 earlier versions.
875
876 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
877 will now result in transliteration to the code page specified for the Firebird driver
878 if the assigned string has a different code page. FPC 3.0.0 onwards only.
879
880 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
881 is ignored and the lc_ctype value, when the database is opened, is set to align with
882 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
883 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
884 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
885 the GETACP is used to determine the Windows code page.
886
887 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
888 name used as the lc_ctype when the database was opened. Only valid while the
889 Database is connected.
890
891 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
892 id that corresponds to the DefaultCharSetName.
893
894 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
895
896 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
897 path is given and database attach fails due to access permission issues on the
898 temp directory or security database, then the attach is retried with "localhost:"
899 prefixing the databasename. This should avoid problems when the database has to
900 be accessed by a local (e.g. classic) server and libfbembed is used.
901
902 2. Windows: revised search order for Firebird DLL:
903 i. The Firebird Embedded Server in the application Directory.
904 ii. If the FIREBIRD environment variable is set then the directory this
905 points to is searched for the FB Client DLL and then then underlying
906 "bin" directory.
907 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
908 is used to locate the Firebird installation directory and the underlying
909 "bin" directory is searched for the FB Client DLL.
910 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
911 are searched for the FB Client DLL.
912 v. The PATH Environment variable is used to search for the FB Client DLL.
913 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
914
915 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
916 See doc/readme.scriptengine and example applications.
917
918 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
919 simplify the use of the embedded firebird server on both Linux and Windows platforms.
920 See dpc/readme.localdatabase and example applications.
921
922 5. IBDynamicGrid: Reordering on column header click should now also work for
923 dynamic columns.
924
925 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
926 between incrementing/decrementing the lock count and signalling the event.
927
928 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
929
930 1.3.2 was never formally released and only made available as beta copies.
931
932 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
933
934 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
935
936 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
937
938 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
939 i.e. when it is a calculated field
940
941 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
942 This problem was due to a race condition between recalculating row heights and
943 determining which row was selected by the mouse click. The row height calculation
944 is now deferred by an extra trip round the message loop allowing the row to
945 be always calculated on the current grid layout rather than risking it being
946 calculated on the grid layout after the expanded row has been shrunk.
947
948 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
949 Windows.
950
951 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
952 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
953 to be determined at runtime. See doc/readme.charactersets.html.
954
955 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
956 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
957
958 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
959 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
960 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
961
962 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
963 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
964 implies no truncation.
965
966 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
967
968 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
969 (avoids "Not in Edit Mode" error).
970
971 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
972
973 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
974 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
975
976 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
977
978 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
979
980 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
981
982 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
983
984 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
985
986 1. OnCloseUp Event Handler added to TDBLookupProperties
987
988 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
989 problem with row size when exception is called.
990
991 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
992
993 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
994 in a TCustomComboBox and ignores return key if in a TCustomMemo
995
996 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
997 keyed in i.e. when autocomplete not performed
998
999 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1000 console mode applications with all LCL required functions (builtin dialogs and
1001 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1002 not included in your project, IBX should compile and link with a console mode program.
1003 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1004 console mode application or the IDE will automatically assume that your
1005 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1006
1007 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1008 to use the built in dialogs and cursor management. IBDialogs is
1009 included by default if "ibexpress" is in your project source's "uses" clause.
1010 This should be the case for all projects created through the IDE. This is why
1011 you do not want to add the ibexpress package to console mode applications. The
1012 ibexpressconsolemode package has been created to allow console mode programs
1013 to avoid adding LCL dependencies when using IBX, while still having the
1014 unit search paths set up correctly.
1015
1016 Existing users should check to ensure that the "ibexpress" unit is included in
1017 each project's source file (*.lpr).
1018
1019 You may find that in order for the IDE to recognise that ibexpressconsolemode
1020 exists, you have to first open the package in the IDE and then close it. This
1021 adds it to the most recently accessed packages list. To make it permanently
1022 available, add the package name to lazarus' staticpackages.inc file.
1023
1024 Thanks to Julio Jiménez for suggesting support of console mode.
1025
1026 7. SQL Parser can now accept quoted strings that include new lines
1027
1028 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1029 of text on start of edit. This is particularly useful when tabbing to a
1030 column and then inserting text.
1031
1032 9. New Examples provided for IB Services and ISQLMonitor.
1033
1034 10. Fix error when writing to blob streams that recorded only the last buffer
1035 write in the blob stream. In most cases, this did not cause a problem as the
1036 IB Blob Stream is written in a single write. However, with the TDBImage, write
1037 of a graphic type prefix was lost which caused a problem when the image could
1038 not be automatically recognised.
1039
1040 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1041 already open" errors due to random numbers used for the cursor name being identical.
1042
1043 12. IBTable: corrected error that could result in an "Index out of bounds" error
1044 when opening the table and the Primary Key is the last or only column in the
1045 table. Thanks to Rick Hoover for the fix.
1046
1047 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1048 of "UTF-8", and update list of available database character sets. Existing
1049 users should check the current lc_ctype setting in their applications.
1050
1051 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1052
1053 1. Firebird Services: avoid List Index error when opening a service with an
1054 empty Params property.
1055
1056 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1057 Link now set up in Loaded method - avoids occasional failure to apply
1058 SQL markup on initial open.
1059
1060 3. "Employees" example performance improvements when scrolling.
1061
1062 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1063 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1064 random image cached).
1065
1066 5. DBControlGrid: Should now react to changes in panel height at run time.
1067
1068 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1069 even when further rows exist.
1070
1071 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1072 always be derived from panel height and setting this property can cause confusion.
1073 Note for existing projects: to avoid a missing property error at run time,
1074 each form using the DBControlGrid must be opened, updated and saved in the IDE
1075 in order to remove the property value from the lfm.
1076
1077
1078 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1079
1080 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1081 call Prepare before setting parameter values.
1082
1083 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1084
1085 3. Code tidyup and more robust handling of dsql information result vector.
1086
1087 4. Support for centralised handling of transaction status changes. TIBTransaction
1088 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1089 and "AfterExecQuery". The first three are called after the same event is called
1090 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1091 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1092 enable monitoring of transaction status changes for a given transaction to be
1093 handled in a single place. For example, when a change to the dataset occurs
1094 an indicator can be set that shows the user that in order to save changes,
1095 the transaction should be committed. Rather than doing this per dataset, this
1096 can now be done per transaction.
1097
1098 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1099 the dataset is scrolled. However, any changes to the current row are, by default,
1100 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1101 have a new property "DataSetCloseAction" that adds automatic posting of changes
1102 on dataset close. If this property is set to dcDiscardChanges (default) then the
1103 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1104 then IBX will attempt to post any unsaved changes before the dataset is closed
1105 (and after the BeforeClose event handler is called). The exception is when the
1106 dataset is being closed as a result of a transaction rollback. In this case,
1107 no action is taken and any unsaved changes are discarded. This avoids both
1108 unnecessary overhead and the risk that a validation error may occur in the Post
1109 raising an exception and thereby preventing a rollback.
1110
1111 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1112 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1113 width. Display Widths are now corrected by dividing by the max byte width per character.
1114 For UTF8 character sets, the byte width is four and hence the Display Width will be
1115 the byte width divided by 4. The byte width of each character set is determined
1116 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1117 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1118
1119 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1120
1121 8. IBLookupComboEditBox: List should now always be restored to full list when the
1122 control loses focus. Default Key press default interval reduced to 200ms.
1123
1124 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1125 when dataset rows are less than visible rows.
1126
1127 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1128 does not exist or DataSet is empty. More responsive on dataset open. New event
1129 OnRestorePosition. Column sort disabled if no header row.
1130
1131 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1132 while dataset state is dsInsert. Avoids posting errors.
1133
1134 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1135 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1136
1137 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1138
1139 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1140 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1141 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1142 always "posts" the current record regardless or whether or not it may be more appropriate
1143 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1144 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1145 as the first action of the "Post" method and allows the handler to convert the Post
1146 into a Cancel if that is the appropriate action on moving to a different row. This is
1147 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1148 raised here, but it may still be more appropriate to validate a post and signal
1149 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1150
1151 15. On Unix derived systems, the Firebird library name can now be given as a colon
1152 separated list. Each library name on the list is tried in turn, in left to right
1153 order with the first found being used as the firebird library. By default, on Linux,
1154 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1155 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1156
1157 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1158 then it will still attempt to access the database via the Firebird Server and will
1159 require a username and password. If only the pathname is given, then the username
1160 and password should be omitted and the unix file permissions are used to grant
1161 access.
1162
1163 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1164
1165 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1166 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1167 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1168 corresponds to a row of the linked DataSource. Any data aware control on the
1169 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1170
1171 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1172 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1173 takes place during database access. This may be useful when there are performance issues with
1174 the change of cursor. Setting the property to false suppresses the change of cursor.
1175
1176 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1177 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1178 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1179 making all changes permanent immediately rather than when the transaction is explicitly
1180 committed.
1181
1182 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1183 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1184
1185 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000

1187 Development version only.
1188
1189 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1190
1191 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1192 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1193 "Where" and "Having" clauses to implement user specified filters of arbitrary
1194 complexity.
1195
1196 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1197 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1198 These are:
1199
1200 - TIBLookupComboEditBox
1201 - TIBDynamicGrid
1202 - TIBTreeview
1203
1204 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1205 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1206 to revise the available list and restrict it to items that are prefixed by the
1207 typed text (either case sensitive or case insensitive). Autoinsert allows a
1208 newly typed entry to be added to the list dataset and included in the available
1209 list items.
1210
1211 TIBDynamicGrid is a TDBGrid descendent that provides for:
1212 - automatic resizing of selected columns to fill the available row length
1213 - automatic positioning and sizing of a "totals" control, typically at the
1214 column footer, on a per column basis.
1215 - DataSet resorting on header row click, sorting the dataset by the selected column.
1216 A second click on the same header cell reversed the sort order.
1217 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1218 is automatically expanded and a panel superimposed on it. The panel can have any
1219 number of child controls, typically data aware controls with the same datasource
1220 as the grid allowing for editing of additional fields and more complex editors.
1221 - Reselection of the same row following resorting.
1222 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1223 Its properties are specified on a per column basis and allows for one or more
1224 columns to have their values selected from a list provided by a dataset.
1225 Autocomplete and autoinsert are also available. The existing picklist editor
1226 is unaffected by the extension.
1227
1228 TIBTreeView is a data aware TCustomTreeView.
1229
1230 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1231 zero scale will no longer return an error. An Int64 will be returned instead.
1232
1233 4. TIBTransaction now has events for Before and After Transaction End and a new function
1234 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1235
1236 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1237 repeated multiple times.
1238
1239 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1240 check used to get in the way of using Stored Procedures, and "Update or Insert"
1241 statements.
1242
1243 7. Insert, Modify and Delete property Editors now support Query Generation from
1244 Stored Procedures.
1245
1246 8. Three new examples illustrate the use of the new IB Controls
1247
1248
1249 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1250
1251 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1252 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1253 Gabor Boros for reporting this problem and for testing the improvements).
1254
1255 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1256 See readme.field+param.names in the doc folder.
1257
1258 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1259 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1260
1261 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1262
1263 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1264 actions.
1265
1266 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1267 thanks to Yuriy Kopnin for pointing this out).
1268
1269 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1270
1271 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1272 for both fields and parameter setting.
1273
1274 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1275 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1276
1277 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1278 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1279
1280 11. TIBTable now has a property editor for "MasterFields"
1281
1282 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1283 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1284
1285 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1286 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1287

1289 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1290
1291 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1292
1293 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1294
1295 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1296 it is null. This allows for alternative user defined setting of the generator
1297
1298 Many thanks to Julio Jiménez for this fix
1299
1300 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1301 and suggests that the user may have forgotten to install it.
1302
1303 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1304
1305 1. Conditional compilation used to limit registration of TIntegerField to
1306 Lazarus versions less than 1.1
1307
1308 2. When a database connection is created, character set is now by default set
1309 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1310 1250 to 1254.
1311
1312
1313 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1314
1315 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1316
1317
1318 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1319
1320 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1321 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1322
1323 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1324 package is changed to do this (which it should do).
1325
1326 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1327
1328 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1329
1330 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1331
1332 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1333
1334 4. Property editors should now correctly resize.
1335
1336 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1337 (restored original functionality)
1338
1339 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1340 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
