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

1215 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1216
1217 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1218
1219 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1220
1221 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1222 it is null. This allows for alternative user defined setting of the generator
1223
1224 Many thanks to Julio Jiménez for this fix
1225
1226 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1227 and suggests that the user may have forgotten to install it.
1228
1229 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1230
1231 1. Conditional compilation used to limit registration of TIntegerField to
1232 Lazarus versions less than 1.1
1233
1234 2. When a database connection is created, character set is now by default set
1235 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1236 1250 to 1254.
1237
1238
1239 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1240
1241 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1242
1243
1244 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1245
1246 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1247 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1248
1249 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1250 package is changed to do this (which it should do).
1251
1252 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1253
1254 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1255
1256 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1257
1258 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1259
1260 4. Property editors should now correctly resize.
1261
1262 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1263 (restored original functionality)
1264
1265 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1266 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
