1 IBX Change Log version (2.3-3 Build 11348) Fri, 28 Dec 2018 10:04:17 +0000
2
3 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4 and is used to override the default settings in the client side "firebird.conf" This
5 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6 Each line of the string list should be a setting in the same format as "firebird.conf".
7 For example "WireCompression = true" in order to request wire compression on the client side.
8
9 Note: explicit settings in the client side "firebird.conf" appear to take precedence
10 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11 also require a compatible setting in the server side "firebird.conf". For example
12 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13 compression to be used.
14
15 Whether or not WireCompression or WireCrypt are in use can be checked using the information
16 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17 ibx/examples/dbinfo for examples of how to display this information.
18
19 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20 is a "convenience" property. If set the "WireCompression=true" is added to the
21 ConfigOverrides. If unchecked then this setting is removed.
22
23 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24 not "INT64".
25
26 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
27 These are:
28 property TimestampFormat: string;
29 property DateFormat: string;
30 property TimeFormat: string;
31
32 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33 DATETIME and TIME. The format strings use the standard FPC date/time format
34 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
35
36 If any of the above properties are set to an empty string, then the locale default
37 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38 locale default is extended by appending '.zzz' to include milliseconds.
39
40 TIBCSVDataOut by default sets these properties to the empty string, while the other
41 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
42
43 5. New published property for TIBCSVDataOut:
44 property QuoteStrings: boolean (default true)
45
46 If false then strings are unquoted, otherwise, the QuoteChar property value is
47 used to delimit each and every string in the output.
48
49 6. New published properties for TIBCSVDataOut:
50 property FieldSeparator: string;
51 property HeaderSeparator: string;
52
53 Respectively, these provide the separator character(s) used to separate fields
54 in data and header rows. Both default to ','.
55
56 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58 property OnFormatTextString;
59
60 This event handler can be used to process text strings before they are included
61 in the output e.g. to replace unprintable characters with alternative strings.
62 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
63
64 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
65
66 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
67 consistency with SQL queries.
68
69 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
70 When true, SQL statement parameter names are parsed case sensitive. Note for
71 TIBDataSet only applies to Select query.
72
73 11. IBEvents: removing a TIBEvent component from a form should no longer result in
74 an IDE exception.
75
76 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
77
78 1. Remove need to check for IsMultiThread by providing access to GUI timers via
79 IBGUIInterface. Note: master/detail delay timer does not apply to console
80 mode apps.
81
82 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
83 statement. This avoids problems if "Execute Block" is used as the Query.
84
85 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
86 internal SQL tokeniser routines.
87
88 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
89 as a select statement, with or without CTEs.
90
91 5. IBSQLParser: parser now recognises the "ROWS" clause.
92
93 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
94 internal SQL tokeniser routines.
95
96 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
97 being raised for valid set statements processed by a data formatter.
98
99 8. New published property for TIBDatabase and TIBXServicesConnection. This is
100 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
101 the path of the Firebird Library used by the database/services connection.
102
103 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
104 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
105 services connection.
106
107 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
108 or param name is not a valid SQL identifier.
109
110 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
111 view of whether the text box should be editable when no DataSource is specified.
112 TIBLookupComboEditBox has been updated to workaround this problem. As long as
113 ReadOnly is false, the text box is editable when no DataSource is specified.
114
115 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
116 the FBLIB environment variable. If you do not want to permit this then you
117 must modify the Register procedure in the design/IBDBReg.pas unit to remove
118 this setting.
119
120 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
121
122 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
123 Utf8EscapeControlChars
124
125 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
126
127 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
128 all previous copies of the IBX source code tree before installing this release.
129
130 The IBX packages used by most users have not changed, with one exception. The
131 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
132 to use the IBServices unit in your applications, please add the iblegacyServices
133 to the list of dependencies. To do this, open the Project Inspector and select
134 Add->New Requirement and select "ibLegacyServices" from the list of available
135 packages.
136
137 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
138 the IBServices unit providing what is intended to be a clearer and easier to
139 use set of IB Services components. See Chapter 10 of the IBX User Guide for
140 more information and the guide to "Firebird Service Management Using IBX".
141 As indicated above, the legacy services components are still available and
142 provided in a separate package. There is no need to update working applications
143 using the older versions except for an additional package dependency.
144
145 2. The IBX packages and source code tree have been re-organised in an attempt to
146 finally get rid of the "duplicate ppu" warnings. This re-organisation should
147 not affect existing users. Section 2.3 of the IBX User Guide describes the
148 new set of IBX packages.
149
150 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
151 updated to use the new Services API components.
152
153 4. The iblocal package has been updated to use the new Services API components.
154
155 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
156 TIBXSecurityService. It had been wrongly classified in the previous version
157 as a per database configuration item. It is global to a server and hence
158 correctly positioned as part of the Security Package. In the DBAdmin example,
159 the setting has moved to the mappings page.
160
161 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
162 are ignored.
163
164 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
165 closed before the database is dropped. Before and After Disconnect event handlers
166 are also fired.
167
168 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
169 is started and not just the first time.
170
171 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
172 depenendency with comp type.
173
174 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
175
176 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
177 then this is recognised and not ignored.
178
179 12. TIBDataSet, TIBQuery, TIBTable: additions:
180 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
181 function GetPerfStatistics(var stats: TPerfCounters): boolean;
182 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
183
184 GetRowsAffected returns the affected row counts from the last insert/update/delete
185 if EnableStatistics = true then GetPerfStatistics returns the current stats
186 counters for the select query. Note: stats accumulate after each fetch from
187 the database. To get total query cost after open, call the "Last" method
188 and then GetPerfStatistics.
189
190 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
191
192 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
193 in parenthesises.
194
195 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
196 SQL identifiers are always delimited by double quotes. If false, then they are
197 only delimited if the identifier is a reserved word, contains lower case or special
198 characters. Set this property to true to retain previous behaviour.
199
200 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
201 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
202
203 16. TIBDataSet, TIBQuery, TIBTable: addition:
204 property MasterDetailDelay: integer {defaults to zero}
205
206 When non-zero and the dataset is a detail table referencing a master table
207 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
208 then a synchronisation delay is added (in milliseconds) between the master
209 row changing and the detail dataset being re-opened. If the master dataset
210 is scrolled before the delay expires then the delay is reset. This can be used
211 to avoid performance overheads when scrolling through a large master dataset.
212
213 Note: uses fptimer and hence requires a thread manager. Under Linux the
214 chreads unit must be included in your project. TTimer is not used in order
215 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
216
217 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
218 with Extract Option eoDatabase.
219
220 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
221 When a deLayoutChanged event is reported on the ListSource dataset, the
222 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
223 relationship with the control's datasource (master).
224
225 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
226
227 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
228 stubs. Pedantic fix really, as procedures output in dependency order anyway.
229
230 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
231 DDL (Firebird 3 and later only).
232
233 22. TIBLookupComboBox Autocomplete Fixes:
234 i. Only appended text is now selected after autocomplete.
235 ii. Uppercase keys no longer ignored for autocomplete.
236 iii. Retain Prefix case is now honoured correctly.
237 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
238 before autocomplete performed. i.e. behaviour now the same as when
239 no DataSource assigned.
240
241 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
242 between SQL statements.
243
244 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
245 ObjectNames are converted to upper case before matching against metadata object
246 names, unless the objectname is delimited by double quotes, in which case, the
247 double quotes are removed and the remaining string is used (unmodified) to match
248 against the metadata object name.
249
250 If true then the ObjectName is used as is without modification and matched
251 against the metadata object name. No attempt is made to remove double quotes.
252
253 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
254 with eoTrigger, these extract types can be used to select only Database Triggers,
255 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
256
257 26. TIBXScript: If an exception occurs during the processing of a statement, the
258 statement separate character is now reset to the default (';').
259
260 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
261
262 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
263 a commit or reconnect statement and instead activated only when next SQL statement
264 is executed.
265
266 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
267
268 30. TIBXScript: case insensitive regex now used when matching statements instead of
269 converting statement to upper case.
270
271 31. TIBExtract: metadata comments now supported. New published property
272 IncludeMetaDataComments (default true). If true then metadata comments included
273 in extracted DDL. New Extract Object member eoComments. This may be used with
274 ExtractObject method to list all metadata comments.
275
276 32. TIBExtract: ListObjectNames method added.
277
278 33. Updated Database component editor to support additional connection string
279 types.
280
281 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
282
283 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
284 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
285 RELEASE.
286
287 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
288
289 1. IBExtract: Identity columns - add additional check for null column for generator name.
290
291 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
292 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
293 information). However, this is also a very useful mechanism for returning updated computed by
294 column values. Values returned as a result of executing an Insert or Update statement
295 replace existing values in the current row for each corresponding column.
296
297 Previously, if a dataset's select query included read only (computed by) fields then
298 an automatic row refresh was performed after an insert or update query had been processed,
299 irrespective of the setting of the "ForcedUpdates" property. This has changed such
300 that an automatic refresh is no longer performed if an insert or update query contains
301 a returning clause that updates one or more fields on the current row. A full row
302 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
303 field values and the select query contains read only fields. Use of Insert/update
304 returning should be significantly more efficient than executing a refresh query.
305
306 This behaviour change is intended to be backwards compatible and there should be no need to change
307 existing programs, other than to improve performance by using the new capability.
308
309 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
310 they are called when the dataset row is being deleted, there is no value in
311 updating the current record from the query result. Instead, a new event handler
312 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
313 an OnDeleteReturning event handler is provided then it is called with the IResults returned
314 by the query. The event handler can then interrogate the query results and
315 perform whatever action is necessary. For example to confirm, to the user,
316 the deletion of a row with the returned values.
317
318 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
319 any Computed By or Identity Columns. The IBTables example has been updated to
320 illustrate the computation of the employee Full Name on update.
321
322 5. TIBTable: The GeneratorField property is now published.
323
324 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
325 When InsertSQL is generated, the Identity columns are not included in the list of values to
326 be inserted. A RETURNING clause is added to the insert statement to return the value of
327 each Identity column after the insert is executed.
328
329 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
330 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
331 Insert..Returning clause.
332
333 8. TIBGenerator: small performance improvement by not preparing query each time
334 a new value is generated.
335
336 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
337
338 10. Property editors will now sync table name to a System Table when "Include System
339 Tables" is selected and the query is for a System Table.
340
341 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
342 values are no longer converted to milliseconds from TDateTime and then back again
343 to TDateTime (the conversion to milliseconds is the default TDataset approach).
344
345 12. Property Editors handling of Stored Procedures.
346 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
347 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
348 query).
349 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
350
351 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
352 can be used to select a package. If non-empty, the stored procedure name is
353 expected to be a stored procedure defined in the specified package and the
354 generated SQL will be as required for a stored procedure located in a package.
355
356 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
357 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
358 which a stored procedure can be selected. With no package name selected, non-package
359 stored procedures are listed.
360
361 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
362 for password on reconnect.
363
364 16. TIBDatabase: use IAttachment for connection default character set id, code page
365 and character set name.
366
367 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
368 DB info lookups"
369
370 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
371
372 19. Add a property Editor for TIBUpdate.RefreshSQL.
373
374 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
375 parameters. This stops an exception being raised when the field cannot be
376 located in the record buffer.
377
378 21. Property Editors now automatically include System Tables when opened and when the query table
379 is a System Table.
380
381 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
382 This avoids errors due to a stale SQRB or SRB being used for the next query.
383
384 23. IBServices: Service attach parameters now include "expected_db". This is used to
385 add the SPB item isc_spb_expected_db. This names a database using
386 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
387 database. examples/services re-written to illustrate use of "expected_db".
388
389 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
390 This avoids truncated backups when the server returns a timeout (busy) response.
391
392 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
393
394 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
395 databasenames. These are respectively expanded to the local system's temp directory
396 (including trailing delimiter) or to a prescribed data directory (including
397 trailing delimiter). Under Unix systems the data directory is a hidden directory
398 in the user's home directory. The hidden directory name is either the string returned
399 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
400 Under Windows, the directory is the same as the Data Directory as decribed
401 above but instead prefixed by the User's application data path. These may be
402 used to improve application portability for Personal Databases.
403
404 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
405 this has not worked for a long time and is not useful either. FieldDefs should be
406 managed using the Fields Editor as with any other dataset. To access the fields
407 editor for a TIBTable component, double click on the component. The fields editor
408 is then displayed.
409
410 28. TIBDatabaseInfo: new properties/function
411 * DateDBCreated (returns date/time database created)
412 * TransactionCount (returns no. of active transactions)
413 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
414 * PagesFree (Firebird 3 or later)
415 * PagesUsed (Firebird 3 or later)
416 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
417 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
418
419 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
420
421 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
422
423 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
424 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
425
426 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
427 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
428 firing during backup and restore.
429
430 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
431 for verbose output using the new property "StatisticsRequested".
432 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
433
434 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
435
436 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
437 palette. This uses the online validation feature added in Firebird 2.5. The
438 services's properties enable inclusion/exclusion of tables and indexes using
439 regular expressions. See.
440 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
441
442 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
443 option on a database.
444
445 37. TIBCustomService: Assign method implemented to allow copying of service login
446 context between service API components. "Detach" method now only detaches
447 service when last reference to the service interface detaches. Tidy up of
448 code for SetActive and Attach methods including password hiding.
449
450 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
451 and used to determine the auth method and protocol used for the connection.
452
453 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
454 a Create Database Statement generated by IBX.
455
456 40. All IBServices now have an additional published property "PortNo". This may
457 be set to a non-standard port number when necessary. If zero then the default
458 port number is used.
459
460 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
461 and not just the mouse.
462
463 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
464
465 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
466 image index and selected image index for each node to be set from a database field.
467
468 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
469 then database schema includes grants to all users. If not present then the
470 only user grants included are those to User PUBLIC.
471
472 45. TIBTreeView: performance improvement. When expanding include both expanded node
473 and child nodes in dataset.
474

476 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
477
478 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
479 changes.
480
481 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
482 Bug could result in truncated multi-byte character set values.
483
484 3. Changes consequential on moving fbintf character set utility functions from
485 IFirebirdAPI to IAttachment.
486
487 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
488
489 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
490 results in autocomplete ignoring prefix text.
491
492 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
493 entering a new name into the text box.
494
495 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
496 Firebird rather than recomputing it.
497
498 8. Property Editor positioning tidy up: All IBX Property editors should now be
499 screen centre. Previously some were "poDesigned" which may be inappropriate
500 for multi monitor desktops.
501
502 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
503
504 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
505 a transaction and always reset the object.
506
507 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
508
509 13. TIBXScript: Allow for override of database filename in Create Database statements.
510
511 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
512 to a gbak format archive.
513
514 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
515
516 16. IBLocaldb: Drop database if error creating an empty database.
517
518 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
519 unless selected node not in current dataset.
520
521 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
522 to TIBCustomService, and IBlocalDB code tidy up.
523
524 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
525 behaviour due to uninitialised variable.
526
527 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
528 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
529
530 21. IBSQL: When Database changed ensure that all resources are freed.
531
532 22. IBCustomDataset: When database changed ensure that queries an unprepared.
533
534 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
535 * Line Wrap on SQL Token boundaries (on user command)
536 * auto-complete table names in drop down list of table names
537 * Double click on tablename or field name adds to SQL text
538
539 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
540
541 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
542 TVariantArray. Seems to avoid memory corruption in Windows (probably a
543 workaround for a problem in fpc 3.0.4 win64).
544
545 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
546
547 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
548
549 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
550
551 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
552 include remote system name.
553
554 2. TIBExtract: No longer include comment header and COMMIT statement for empty
555 tables when data included in output.
556
557 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
558 and timing information to be written to stdout. This may be used to locate
559 performance bottlenecks.
560
561 4. SQLParser: only call "OnChanging" event handler when value is different.
562
563 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
564
565 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
566 that BindFields is called when the query is next activated. Avoids FieldName
567 not found error.
568
569 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
570 purpose and allows the programmer to define any action they want for Update, Insert
571 or Delete. This may be complex SQL (similar to a Trigger), application specific
572 filtering of updates, or use of statements such as Grant or Revoke instead of
573 normal DML. See User Manual for more information.
574
575 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
576
577 1. TIBEvents: Fix uninitialised variable that could result in lost events.
578
579 2. TIBExtract: Added support for FB3 "USAGE" privilege.
580
581 3. TIBExtract: data formatted as Charset set "octets" is now output using
582 hexadecimal notation.
583
584 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
585 using a simple XML format.
586
587 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
588 grants to these objects.
589
590 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
591 dependency problems restoring complex databases.
592
593 7. TIBXScript: This component has been restructured to allow for the processing of
594 embedded XML in INSERT statements and to support interactive sources in addition
595 to non-interactive data sources such as files.
596
597 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
598
599 9. TIBXScript: ISQL compatiable Set statements are now supported:
600 SET SQL DIALECT
601 SET TERM
602 SET AUTODDL
603 SET BAIL
604 SET ECHO
605 SET COUNT
606 SET STATS
607 SET NAMES <character set>
608
609 10. IBVersion unit added to hold current IBX Version Number information.
610
611 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
612 and domain definitions.
613
614 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
615 fully supported.
616
617 13. TIBExtract: when a database dump includes data, the generator values are now also set.
618
619 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
620
621 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
622
623 See also doc/IBX4LazarusGuide.pdf for important information on
624 upgrading to IBX2.
625
626 1. Size property of TIBStringField is now the width in characters of the field
627 and not the byte length. This applies only to multi-byte character sets such
628 as UTF8. The original approach aligned with TStringField. However, the TStringField
629 code is not recognised as a bug and hence this change to align the behaviour.
630 The TStringField change is expected in fpc 3.2.0.
631
632 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
633 true (default) then Size property value saved in the lfm is ignored. Size is
634 always set from the dynamic information read from the database. It is unclear
635 why anyone would want to override this and set Size to false.
636
637 3. ibxscript: should now handle correctly a Case..End statement within a procedure
638 block.
639
640 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
641 exist when an attempt is made to connect to it (run time only) then an attempt
642 is made to create the database.
643
644 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
645 has been successfully created as a result of a call to CreateDatabase or when
646 creating a database after it was found not to exist.
647
648 6. DBControlGrid: a race condition could result in the wrong row image being
649 written to the cache. This has been avoided by a trip round the message
650 loop before rendering the row image.
651
652 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
653 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
654 known to risk corrupt rendering of row images when the control is first
655 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
656 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
657
658 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
659 a TDateEdit control located on an editor panel.
660
661 9. TIBExtract: brought up-to-date plus many bug fixes.
662
663 10. DBControlGrid: Removed memory leak when updating rows.
664
665 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
666
667 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
668
669 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
670 when target codepage is CP_NONE. This is a workaround for
671 http://bugs.freepascal.org/view.php?id=30622.
672
673 2. DBLog option removed from TIBStatisticalService - not supported by server
674 since Firebird 1.5.
675
676 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
677 similar.
678
679 4. IBCodePage: updated mapping between codepages and character id.
680
681 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
682 Firebird. Character sets with a char width of two are not UTF16.
683
684 6. Strings received from the database are now always transliterated into UTF8
685 regardless of the database character set or connection character set. This
686 is for compatibility with the LCL.
687
688 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
689
690 1. IBBlob: Defer reading of blob until read method called. This avoids having to
691 read in an entire blob just to get the size of the blob. General performance
692 improvement when opening datasets containing blobs.
693
694 2. Clearing a Blob now sets the corresponding field's modified flag.
695
696 3. IBLookupCombo: When not performing auto-complete, original query sort order
697 is now used.
698
699 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
700 determined.
701
702 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
703
704 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
705 lazarus 1.6.0
706
707 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
708 compilation error.
709
710 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
711
712 1. No character set specified for connection: when a text blob is retrieved, the
713 character set is determined by looking up the native character set using then
714 Firebird API. Otherwise a text mode blob is assumed to have the same character
715 set as the connection.
716
717 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
718 for Login Dialog returing a change to the database path.
719
720 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
721 to be changed from that given in the TIBDatabase/TIBServer component and for the
722 entered value to be saved on a project specific basis (design time only).
723
724 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
725 column fieldname. If they are the same then it is acts as a look up for the KeyValue
726 Otherwise, it sets the column text to the selected ListField Value.
727
728 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
729 column width.
730
731 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
732 and a case insensitive search is requested.
733
734 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
735 or column ListSource.
736
737 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
738 unprepare) when closing and the text has not changed.
739
740 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
741 Less likely to cause a cursor re-use error on Windows.
742
743 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
744 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
745
746 11. TIBTreeView: Guard against nil destination on record changed
747
748 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
749 string type with the code page set to reflect the returned field encoding after
750 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
751 earlier versions.
752
753 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
754 will now result in transliteration to the code page specified for the Firebird driver
755 if the assigned string has a different code page. FPC 3.0.0 onwards only.
756
757 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
758 is ignored and the lc_ctype value, when the database is opened, is set to align with
759 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
760 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
761 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
762 the GETACP is used to determine the Windows code page.
763
764 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
765 name used as the lc_ctype when the database was opened. Only valid while the
766 Database is connected.
767
768 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
769 id that corresponds to the DefaultCharSetName.
770
771 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
772
773 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
774 path is given and database attach fails due to access permission issues on the
775 temp directory or security database, then the attach is retried with "localhost:"
776 prefixing the databasename. This should avoid problems when the database has to
777 be accessed by a local (e.g. classic) server and libfbembed is used.
778
779 2. Windows: revised search order for Firebird DLL:
780 i. The Firebird Embedded Server in the application Directory.
781 ii. If the FIREBIRD environment variable is set then the directory this
782 points to is searched for the FB Client DLL and then then underlying
783 "bin" directory.
784 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
785 is used to locate the Firebird installation directory and the underlying
786 "bin" directory is searched for the FB Client DLL.
787 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
788 are searched for the FB Client DLL.
789 v. The PATH Environment variable is used to search for the FB Client DLL.
790 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
791
792 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
793 See doc/readme.scriptengine and example applications.
794
795 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
796 simplify the use of the embedded firebird server on both Linux and Windows platforms.
797 See dpc/readme.localdatabase and example applications.
798
799 5. IBDynamicGrid: Reordering on column header click should now also work for
800 dynamic columns.
801
802 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
803 between incrementing/decrementing the lock count and signalling the event.
804
805 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
806
807 1.3.2 was never formally released and only made available as beta copies.
808
809 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
810
811 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
812
813 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
814
815 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
816 i.e. when it is a calculated field
817
818 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
819 This problem was due to a race condition between recalculating row heights and
820 determining which row was selected by the mouse click. The row height calculation
821 is now deferred by an extra trip round the message loop allowing the row to
822 be always calculated on the current grid layout rather than risking it being
823 calculated on the grid layout after the expanded row has been shrunk.
824
825 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
826 Windows.
827
828 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
829 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
830 to be determined at runtime. See doc/readme.charactersets.html.
831
832 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
833 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
834
835 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
836 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
837 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
838
839 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
840 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
841 implies no truncation.
842
843 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
844
845 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
846 (avoids "Not in Edit Mode" error).
847
848 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
849
850 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
851 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
852
853 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
854
855 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
856
857 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
858
859 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
860
861 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
862
863 1. OnCloseUp Event Handler added to TDBLookupProperties
864
865 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
866 problem with row size when exception is called.
867
868 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
869
870 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
871 in a TCustomComboBox and ignores return key if in a TCustomMemo
872
873 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
874 keyed in i.e. when autocomplete not performed
875
876 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
877 console mode applications with all LCL required functions (builtin dialogs and
878 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
879 not included in your project, IBX should compile and link with a console mode program.
880 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
881 console mode application or the IDE will automatically assume that your
882 application is GUI based. Instead, you should include the ibexpressconsolemode package.
883
884 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
885 to use the built in dialogs and cursor management. IBDialogs is
886 included by default if "ibexpress" is in your project source's "uses" clause.
887 This should be the case for all projects created through the IDE. This is why
888 you do not want to add the ibexpress package to console mode applications. The
889 ibexpressconsolemode package has been created to allow console mode programs
890 to avoid adding LCL dependencies when using IBX, while still having the
891 unit search paths set up correctly.
892
893 Existing users should check to ensure that the "ibexpress" unit is included in
894 each project's source file (*.lpr).
895
896 You may find that in order for the IDE to recognise that ibexpressconsolemode
897 exists, you have to first open the package in the IDE and then close it. This
898 adds it to the most recently accessed packages list. To make it permanently
899 available, add the package name to lazarus' staticpackages.inc file.
900
901 Thanks to Julio Jiménez for suggesting support of console mode.
902
903 7. SQL Parser can now accept quoted strings that include new lines
904
905 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
906 of text on start of edit. This is particularly useful when tabbing to a
907 column and then inserting text.
908
909 9. New Examples provided for IB Services and ISQLMonitor.
910
911 10. Fix error when writing to blob streams that recorded only the last buffer
912 write in the blob stream. In most cases, this did not cause a problem as the
913 IB Blob Stream is written in a single write. However, with the TDBImage, write
914 of a graphic type prefix was lost which caused a problem when the image could
915 not be automatically recognised.
916
917 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
918 already open" errors due to random numbers used for the cursor name being identical.
919
920 12. IBTable: corrected error that could result in an "Index out of bounds" error
921 when opening the table and the Primary Key is the last or only column in the
922 table. Thanks to Rick Hoover for the fix.
923
924 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
925 of "UTF-8", and update list of available database character sets. Existing
926 users should check the current lc_ctype setting in their applications.
927
928 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
929
930 1. Firebird Services: avoid List Index error when opening a service with an
931 empty Params property.
932
933 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
934 Link now set up in Loaded method - avoids occasional failure to apply
935 SQL markup on initial open.
936
937 3. "Employees" example performance improvements when scrolling.
938
939 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
940 TFrame. Force recaching of selected frame to avoid GTK race (results in a
941 random image cached).
942
943 5. DBControlGrid: Should now react to changes in panel height at run time.
944
945 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
946 even when further rows exist.
947
948 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
949 always be derived from panel height and setting this property can cause confusion.
950 Note for existing projects: to avoid a missing property error at run time,
951 each form using the DBControlGrid must be opened, updated and saved in the IDE
952 in order to remove the property value from the lfm.

955 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
956
957 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
958 call Prepare before setting parameter values.
959
960 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
961
962 3. Code tidyup and more robust handling of dsql information result vector.
963
964 4. Support for centralised handling of transaction status changes. TIBTransaction
965 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
966 and "AfterExecQuery". The first three are called after the same event is called
967 for an IBCustomDataSet descendent using the Transaction. The fourth is called
968 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
969 enable monitoring of transaction status changes for a given transaction to be
970 handled in a single place. For example, when a change to the dataset occurs
971 an indicator can be set that shows the user that in order to save changes,
972 the transaction should be committed. Rather than doing this per dataset, this
973 can now be done per transaction.
974
975 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
976 the dataset is scrolled. However, any changes to the current row are, by default,
977 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
978 have a new property "DataSetCloseAction" that adds automatic posting of changes
979 on dataset close. If this property is set to dcDiscardChanges (default) then the
980 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
981 then IBX will attempt to post any unsaved changes before the dataset is closed
982 (and after the BeforeClose event handler is called). The exception is when the
983 dataset is being closed as a result of a transaction rollback. In this case,
984 no action is taken and any unsaved changes are discarded. This avoids both
985 unnecessary overhead and the risk that a validation error may occur in the Post
986 raising an exception and thereby preventing a rollback.
987
988 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
989 In earlier versions, the Display Width was set to the maximum byte width rather than the character
990 width. Display Widths are now corrected by dividing by the max byte width per character.
991 For UTF8 character sets, the byte width is four and hence the Display Width will be
992 the byte width divided by 4. The byte width of each character set is determined
993 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
994 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
995
996 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
997
998 8. IBLookupComboEditBox: List should now always be restored to full list when the
999 control loses focus. Default Key press default interval reduced to 200ms.
1000
1001 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1002 when dataset rows are less than visible rows.
1003
1004 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1005 does not exist or DataSet is empty. More responsive on dataset open. New event
1006 OnRestorePosition. Column sort disabled if no header row.
1007
1008 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1009 while dataset state is dsInsert. Avoids posting errors.
1010
1011 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1012 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1013
1014 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1015
1016 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1017 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1018 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1019 always "posts" the current record regardless or whether or not it may be more appropriate
1020 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1021 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1022 as the first action of the "Post" method and allows the handler to convert the Post
1023 into a Cancel if that is the appropriate action on moving to a different row. This is
1024 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1025 raised here, but it may still be more appropriate to validate a post and signal
1026 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1027
1028 15. On Unix derived systems, the Firebird library name can now be given as a colon
1029 separated list. Each library name on the list is tried in turn, in left to right
1030 order with the first found being used as the firebird library. By default, on Linux,
1031 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1032 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1033
1034 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1035 then it will still attempt to access the database via the Firebird Server and will
1036 require a username and password. If only the pathname is given, then the username
1037 and password should be omitted and the unix file permissions are used to grant
1038 access.
1039
1040 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1041
1042 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1043 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1044 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1045 corresponds to a row of the linked DataSource. Any data aware control on the
1046 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1047
1048 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1049 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1050 takes place during database access. This may be useful when there are performance issues with
1051 the change of cursor. Setting the property to false suppresses the change of cursor.
1052
1053 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1054 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1055 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1056 making all changes permanent immediately rather than when the transaction is explicitly
1057 committed.
1058
1059 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1060 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1061
1062 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1063
1064 Development version only.
1065
1066 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1067
1068 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1069 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1070 "Where" and "Having" clauses to implement user specified filters of arbitrary
1071 complexity.
1072
1073 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1074 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1075 These are:
1076
1077 - TIBLookupComboEditBox
1078 - TIBDynamicGrid
1079 - TIBTreeview
1080
1081 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1082 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1083 to revise the available list and restrict it to items that are prefixed by the
1084 typed text (either case sensitive or case insensitive). Autoinsert allows a
1085 newly typed entry to be added to the list dataset and included in the available
1086 list items.
1087
1088 TIBDynamicGrid is a TDBGrid descendent that provides for:
1089 - automatic resizing of selected columns to fill the available row length
1090 - automatic positioning and sizing of a "totals" control, typically at the
1091 column footer, on a per column basis.
1092 - DataSet resorting on header row click, sorting the dataset by the selected column.
1093 A second click on the same header cell reversed the sort order.
1094 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1095 is automatically expanded and a panel superimposed on it. The panel can have any
1096 number of child controls, typically data aware controls with the same datasource
1097 as the grid allowing for editing of additional fields and more complex editors.
1098 - Reselection of the same row following resorting.
1099 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1100 Its properties are specified on a per column basis and allows for one or more
1101 columns to have their values selected from a list provided by a dataset.
1102 Autocomplete and autoinsert are also available. The existing picklist editor
1103 is unaffected by the extension.
1104
1105 TIBTreeView is a data aware TCustomTreeView.
1106
1107 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1108 zero scale will no longer return an error. An Int64 will be returned instead.
1109
1110 4. TIBTransaction now has events for Before and After Transaction End and a new function
1111 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1112
1113 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1114 repeated multiple times.
1115
1116 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1117 check used to get in the way of using Stored Procedures, and "Update or Insert"
1118 statements.
1119
1120 7. Insert, Modify and Delete property Editors now support Query Generation from
1121 Stored Procedures.
1122
1123 8. Three new examples illustrate the use of the new IB Controls
1124
1125
1126 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1127
1128 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1129 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1130 Gabor Boros for reporting this problem and for testing the improvements).
1131
1132 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1133 See readme.field+param.names in the doc folder.
1134
1135 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1136 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1137
1138 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1139
1140 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1141 actions.
1142
1143 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1144 thanks to Yuriy Kopnin for pointing this out).
1145
1146 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1147
1148 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1149 for both fields and parameter setting.
1150
1151 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1152 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1153
1154 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1155 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1156
1157 11. TIBTable now has a property editor for "MasterFields"
1158
1159 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1160 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1161
1162 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1163 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1164
1165
1166 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1167
1168 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1169
1170 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1171
1172 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1173 it is null. This allows for alternative user defined setting of the generator
1174
1175 Many thanks to Julio Jiménez for this fix
1176
1177 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1178 and suggests that the user may have forgotten to install it.
1179
1180 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1181
1182 1. Conditional compilation used to limit registration of TIntegerField to
1183 Lazarus versions less than 1.1
1184
1185 2. When a database connection is created, character set is now by default set
1186 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1187 1250 to 1254.
1188
1189
1190 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1191
1192 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1193
1194
1195 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1196
1197 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1198 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1199
1200 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1201 package is changed to do this (which it should do).
1202
1203 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1204
1205 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1206
1207 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1208
1209 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1210
1211 4. Property editors should now correctly resize.
1212
1213 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1214 (restored original functionality)
1215
1216 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1217 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
