1 IBX Change Log version (2.3-3 Build 11288) 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 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
24
25 1. Remove need to check for IsMultiThread by providing access to GUI timers via
26 IBGUIInterface. Note: master/detail delay timer does not apply to console
27 mode apps.
28
29 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
30 statement. This avoids problems if "Execute Block" is used as the Query.
31
32 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
33 internal SQL tokeniser routines.
34
35 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
36 as a select statement, with or without CTEs.
37
38 5. IBSQLParser: parser now recognises the "ROWS" clause.
39
40 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
41 internal SQL tokeniser routines.
42
43 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
44 being raised for valid set statements processed by a data formatter.
45
46 8. New published property for TIBDatabase and TIBXServicesConnection. This is
47 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
48 the path of the Firebird Library used by the database/services connection.
49
50 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
51 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
52 services connection.
53
54 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
55 or param name is not a valid SQL identifier.
56
57 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
58 view of whether the text box should be editable when no DataSource is specified.
59 TIBLookupComboEditBox has been updated to workaround this problem. As long as
60 ReadOnly is false, the text box is editable when no DataSource is specified.
61
62 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
63 the FBLIB environment variable. If you do not want to permit this then you
64 must modify the Register procedure in the design/IBDBReg.pas unit to remove
65 this setting.
66
67 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
68
69 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
70 Utf8EscapeControlChars
71
72 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
73
74 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
75 all previous copies of the IBX source code tree before installing this release.
76
77 The IBX packages used by most users have not changed, with one exception. The
78 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
79 to use the IBServices unit in your applications, please add the iblegacyServices
80 to the list of dependencies. To do this, open the Project Inspector and select
81 Add->New Requirement and select "ibLegacyServices" from the list of available
82 packages.
83
84 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
85 the IBServices unit providing what is intended to be a clearer and easier to
86 use set of IB Services components. See Chapter 10 of the IBX User Guide for
87 more information and the guide to "Firebird Service Management Using IBX".
88 As indicated above, the legacy services components are still available and
89 provided in a separate package. There is no need to update working applications
90 using the older versions except for an additional package dependency.
91
92 2. The IBX packages and source code tree have been re-organised in an attempt to
93 finally get rid of the "duplicate ppu" warnings. This re-organisation should
94 not affect existing users. Section 2.3 of the IBX User Guide describes the
95 new set of IBX packages.
96
97 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
98 updated to use the new Services API components.
99
100 4. The iblocal package has been updated to use the new Services API components.
101
102 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
103 TIBXSecurityService. It had been wrongly classified in the previous version
104 as a per database configuration item. It is global to a server and hence
105 correctly positioned as part of the Security Package. In the DBAdmin example,
106 the setting has moved to the mappings page.
107
108 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
109 are ignored.
110
111 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
112 closed before the database is dropped. Before and After Disconnect event handlers
113 are also fired.
114
115 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
116 is started and not just the first time.
117
118 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
119 depenendency with comp type.
120
121 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
122
123 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
124 then this is recognised and not ignored.
125
126 12. TIBDataSet, TIBQuery, TIBTable: additions:
127 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
128 function GetPerfStatistics(var stats: TPerfCounters): boolean;
129 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
130
131 GetRowsAffected returns the affected row counts from the last insert/update/delete
132 if EnableStatistics = true then GetPerfStatistics returns the current stats
133 counters for the select query. Note: stats accumulate after each fetch from
134 the database. To get total query cost after open, call the "Last" method
135 and then GetPerfStatistics.
136
137 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
138
139 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
140 in parenthesises.
141
142 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
143 SQL identifiers are always delimited by double quotes. If false, then they are
144 only delimited if the identifier is a reserved word, contains lower case or special
145 characters. Set this property to true to retain previous behaviour.
146
147 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
148 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
149
150 16. TIBDataSet, TIBQuery, TIBTable: addition:
151 property MasterDetailDelay: integer {defaults to zero}
152
153 When non-zero and the dataset is a detail table referencing a master table
154 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
155 then a synchronisation delay is added (in milliseconds) between the master
156 row changing and the detail dataset being re-opened. If the master dataset
157 is scrolled before the delay expires then the delay is reset. This can be used
158 to avoid performance overheads when scrolling through a large master dataset.
159
160 Note: uses fptimer and hence requires a thread manager. Under Linux the
161 chreads unit must be included in your project. TTimer is not used in order
162 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
163
164 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
165 with Extract Option eoDatabase.
166
167 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
168 When a deLayoutChanged event is reported on the ListSource dataset, the
169 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
170 relationship with the control's datasource (master).
171
172 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
173
174 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
175 stubs. Pedantic fix really, as procedures output in dependency order anyway.
176
177 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
178 DDL (Firebird 3 and later only).
179
180 22. TIBLookupComboBox Autocomplete Fixes:
181 i. Only appended text is now selected after autocomplete.
182 ii. Uppercase keys no longer ignored for autocomplete.
183 iii. Retain Prefix case is now honoured correctly.
184 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
185 before autocomplete performed. i.e. behaviour now the same as when
186 no DataSource assigned.
187
188 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
189 between SQL statements.
190
191 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
192 ObjectNames are converted to upper case before matching against metadata object
193 names, unless the objectname is delimited by double quotes, in which case, the
194 double quotes are removed and the remaining string is used (unmodified) to match
195 against the metadata object name.
196
197 If true then the ObjectName is used as is without modification and matched
198 against the metadata object name. No attempt is made to remove double quotes.
199
200 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
201 with eoTrigger, these extract types can be used to select only Database Triggers,
202 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
203
204 26. TIBXScript: If an exception occurs during the processing of a statement, the
205 statement separate character is now reset to the default (';').
206
207 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
208
209 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
210 a commit or reconnect statement and instead activated only when next SQL statement
211 is executed.
212
213 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
214
215 30. TIBXScript: case insensitive regex now used when matching statements instead of
216 converting statement to upper case.
217
218 31. TIBExtract: metadata comments now supported. New published property
219 IncludeMetaDataComments (default true). If true then metadata comments included
220 in extracted DDL. New Extract Object member eoComments. This may be used with
221 ExtractObject method to list all metadata comments.
222
223 32. TIBExtract: ListObjectNames method added.
224
225 33. Updated Database component editor to support additional connection string
226 types.
227
228 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
229
230 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
231 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
232 RELEASE.
233
234 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
235
236 1. IBExtract: Identity columns - add additional check for null column for generator name.
237
238 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
239 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
240 information). However, this is also a very useful mechanism for returning updated computed by
241 column values. Values returned as a result of executing an Insert or Update statement
242 replace existing values in the current row for each corresponding column.
243
244 Previously, if a dataset's select query included read only (computed by) fields then
245 an automatic row refresh was performed after an insert or update query had been processed,
246 irrespective of the setting of the "ForcedUpdates" property. This has changed such
247 that an automatic refresh is no longer performed if an insert or update query contains
248 a returning clause that updates one or more fields on the current row. A full row
249 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
250 field values and the select query contains read only fields. Use of Insert/update
251 returning should be significantly more efficient than executing a refresh query.
252
253 This behaviour change is intended to be backwards compatible and there should be no need to change
254 existing programs, other than to improve performance by using the new capability.
255
256 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
257 they are called when the dataset row is being deleted, there is no value in
258 updating the current record from the query result. Instead, a new event handler
259 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
260 an OnDeleteReturning event handler is provided then it is called with the IResults returned
261 by the query. The event handler can then interrogate the query results and
262 perform whatever action is necessary. For example to confirm, to the user,
263 the deletion of a row with the returned values.
264
265 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
266 any Computed By or Identity Columns. The IBTables example has been updated to
267 illustrate the computation of the employee Full Name on update.
268
269 5. TIBTable: The GeneratorField property is now published.
270
271 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
272 When InsertSQL is generated, the Identity columns are not included in the list of values to
273 be inserted. A RETURNING clause is added to the insert statement to return the value of
274 each Identity column after the insert is executed.
275
276 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
277 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
278 Insert..Returning clause.
279
280 8. TIBGenerator: small performance improvement by not preparing query each time
281 a new value is generated.
282
283 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
284
285 10. Property editors will now sync table name to a System Table when "Include System
286 Tables" is selected and the query is for a System Table.
287
288 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
289 values are no longer converted to milliseconds from TDateTime and then back again
290 to TDateTime (the conversion to milliseconds is the default TDataset approach).
291
292 12. Property Editors handling of Stored Procedures.
293 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
294 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
295 query).
296 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
297
298 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
299 can be used to select a package. If non-empty, the stored procedure name is
300 expected to be a stored procedure defined in the specified package and the
301 generated SQL will be as required for a stored procedure located in a package.
302
303 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
304 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
305 which a stored procedure can be selected. With no package name selected, non-package
306 stored procedures are listed.
307
308 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
309 for password on reconnect.
310
311 16. TIBDatabase: use IAttachment for connection default character set id, code page
312 and character set name.
313
314 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
315 DB info lookups"
316
317 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
318
319 19. Add a property Editor for TIBUpdate.RefreshSQL.
320
321 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
322 parameters. This stops an exception being raised when the field cannot be
323 located in the record buffer.
324
325 21. Property Editors now automatically include System Tables when opened and when the query table
326 is a System Table.
327
328 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
329 This avoids errors due to a stale SQRB or SRB being used for the next query.
330
331 23. IBServices: Service attach parameters now include "expected_db". This is used to
332 add the SPB item isc_spb_expected_db. This names a database using
333 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
334 database. examples/services re-written to illustrate use of "expected_db".
335
336 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
337 This avoids truncated backups when the server returns a timeout (busy) response.
338
339 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
340
341 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
342 databasenames. These are respectively expanded to the local system's temp directory
343 (including trailing delimiter) or to a prescribed data directory (including
344 trailing delimiter). Under Unix systems the data directory is a hidden directory
345 in the user's home directory. The hidden directory name is either the string returned
346 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
347 Under Windows, the directory is the same as the Data Directory as decribed
348 above but instead prefixed by the User's application data path. These may be
349 used to improve application portability for Personal Databases.
350
351 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
352 this has not worked for a long time and is not useful either. FieldDefs should be
353 managed using the Fields Editor as with any other dataset. To access the fields
354 editor for a TIBTable component, double click on the component. The fields editor
355 is then displayed.
356
357 28. TIBDatabaseInfo: new properties/function
358 * DateDBCreated (returns date/time database created)
359 * TransactionCount (returns no. of active transactions)
360 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
361 * PagesFree (Firebird 3 or later)
362 * PagesUsed (Firebird 3 or later)
363 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
364 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
365
366 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
367
368 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
369
370 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
371 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
372
373 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
374 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
375 firing during backup and restore.
376
377 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
378 for verbose output using the new property "StatisticsRequested".
379 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
380
381 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
382
383 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
384 palette. This uses the online validation feature added in Firebird 2.5. The
385 services's properties enable inclusion/exclusion of tables and indexes using
386 regular expressions. See.
387 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
388
389 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
390 option on a database.
391
392 37. TIBCustomService: Assign method implemented to allow copying of service login
393 context between service API components. "Detach" method now only detaches
394 service when last reference to the service interface detaches. Tidy up of
395 code for SetActive and Attach methods including password hiding.
396
397 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
398 and used to determine the auth method and protocol used for the connection.
399
400 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
401 a Create Database Statement generated by IBX.
402
403 40. All IBServices now have an additional published property "PortNo". This may
404 be set to a non-standard port number when necessary. If zero then the default
405 port number is used.
406
407 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
408 and not just the mouse.
409
410 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
411
412 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
413 image index and selected image index for each node to be set from a database field.
414
415 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
416 then database schema includes grants to all users. If not present then the
417 only user grants included are those to User PUBLIC.
418
419 45. TIBTreeView: performance improvement. When expanding include both expanded node
420 and child nodes in dataset.
421
422
423 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
424
425 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
426 changes.
427
428 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
429 Bug could result in truncated multi-byte character set values.
430
431 3. Changes consequential on moving fbintf character set utility functions from
432 IFirebirdAPI to IAttachment.
433
434 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
435
436 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
437 results in autocomplete ignoring prefix text.
438
439 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
440 entering a new name into the text box.
441
442 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
443 Firebird rather than recomputing it.
444
445 8. Property Editor positioning tidy up: All IBX Property editors should now be
446 screen centre. Previously some were "poDesigned" which may be inappropriate
447 for multi monitor desktops.
448
449 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
450
451 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
452 a transaction and always reset the object.
453
454 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
455
456 13. TIBXScript: Allow for override of database filename in Create Database statements.
457
458 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
459 to a gbak format archive.
460
461 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
462
463 16. IBLocaldb: Drop database if error creating an empty database.
464
465 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
466 unless selected node not in current dataset.
467
468 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
469 to TIBCustomService, and IBlocalDB code tidy up.
470
471 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
472 behaviour due to uninitialised variable.
473
474 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
475 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
476
477 21. IBSQL: When Database changed ensure that all resources are freed.
478
479 22. IBCustomDataset: When database changed ensure that queries an unprepared.
480
481 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
482 * Line Wrap on SQL Token boundaries (on user command)
483 * auto-complete table names in drop down list of table names
484 * Double click on tablename or field name adds to SQL text
485
486 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
487
488 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
489 TVariantArray. Seems to avoid memory corruption in Windows (probably a
490 workaround for a problem in fpc 3.0.4 win64).
491
492 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
493
494 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
495
496 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
497
498 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
499 include remote system name.
500
501 2. TIBExtract: No longer include comment header and COMMIT statement for empty
502 tables when data included in output.
503
504 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
505 and timing information to be written to stdout. This may be used to locate
506 performance bottlenecks.
507
508 4. SQLParser: only call "OnChanging" event handler when value is different.
509
510 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
511
512 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
513 that BindFields is called when the query is next activated. Avoids FieldName
514 not found error.
515
516 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
517 purpose and allows the programmer to define any action they want for Update, Insert
518 or Delete. This may be complex SQL (similar to a Trigger), application specific
519 filtering of updates, or use of statements such as Grant or Revoke instead of
520 normal DML. See User Manual for more information.
521
522 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
523
524 1. TIBEvents: Fix uninitialised variable that could result in lost events.
525
526 2. TIBExtract: Added support for FB3 "USAGE" privilege.
527
528 3. TIBExtract: data formatted as Charset set "octets" is now output using
529 hexadecimal notation.
530
531 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
532 using a simple XML format.
533
534 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
535 grants to these objects.
536
537 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
538 dependency problems restoring complex databases.
539
540 7. TIBXScript: This component has been restructured to allow for the processing of
541 embedded XML in INSERT statements and to support interactive sources in addition
542 to non-interactive data sources such as files.
543
544 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
545
546 9. TIBXScript: ISQL compatiable Set statements are now supported:
547 SET SQL DIALECT
548 SET TERM
549 SET AUTODDL
550 SET BAIL
551 SET ECHO
552 SET COUNT
553 SET STATS
554 SET NAMES <character set>
555
556 10. IBVersion unit added to hold current IBX Version Number information.
557
558 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
559 and domain definitions.
560
561 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
562 fully supported.
563
564 13. TIBExtract: when a database dump includes data, the generator values are now also set.
565
566 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
567
568 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
569
570 See also doc/IBX4LazarusGuide.pdf for important information on
571 upgrading to IBX2.
572
573 1. Size property of TIBStringField is now the width in characters of the field
574 and not the byte length. This applies only to multi-byte character sets such
575 as UTF8. The original approach aligned with TStringField. However, the TStringField
576 code is not recognised as a bug and hence this change to align the behaviour.
577 The TStringField change is expected in fpc 3.2.0.
578
579 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
580 true (default) then Size property value saved in the lfm is ignored. Size is
581 always set from the dynamic information read from the database. It is unclear
582 why anyone would want to override this and set Size to false.
583
584 3. ibxscript: should now handle correctly a Case..End statement within a procedure
585 block.
586
587 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
588 exist when an attempt is made to connect to it (run time only) then an attempt
589 is made to create the database.
590
591 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
592 has been successfully created as a result of a call to CreateDatabase or when
593 creating a database after it was found not to exist.
594
595 6. DBControlGrid: a race condition could result in the wrong row image being
596 written to the cache. This has been avoided by a trip round the message
597 loop before rendering the row image.
598
599 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
600 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
601 known to risk corrupt rendering of row images when the control is first
602 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
603 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
604
605 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
606 a TDateEdit control located on an editor panel.
607
608 9. TIBExtract: brought up-to-date plus many bug fixes.
609
610 10. DBControlGrid: Removed memory leak when updating rows.
611
612 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
613
614 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
615
616 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
617 when target codepage is CP_NONE. This is a workaround for
618 http://bugs.freepascal.org/view.php?id=30622.
619
620 2. DBLog option removed from TIBStatisticalService - not supported by server
621 since Firebird 1.5.
622
623 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
624 similar.
625
626 4. IBCodePage: updated mapping between codepages and character id.
627
628 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
629 Firebird. Character sets with a char width of two are not UTF16.
630
631 6. Strings received from the database are now always transliterated into UTF8
632 regardless of the database character set or connection character set. This
633 is for compatibility with the LCL.
634
635 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
636
637 1. IBBlob: Defer reading of blob until read method called. This avoids having to
638 read in an entire blob just to get the size of the blob. General performance
639 improvement when opening datasets containing blobs.
640
641 2. Clearing a Blob now sets the corresponding field's modified flag.
642
643 3. IBLookupCombo: When not performing auto-complete, original query sort order
644 is now used.
645
646 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
647 determined.
648
649 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
650
651 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
652 lazarus 1.6.0
653
654 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
655 compilation error.
656
657 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
658
659 1. No character set specified for connection: when a text blob is retrieved, the
660 character set is determined by looking up the native character set using then
661 Firebird API. Otherwise a text mode blob is assumed to have the same character
662 set as the connection.
663
664 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
665 for Login Dialog returing a change to the database path.
666
667 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
668 to be changed from that given in the TIBDatabase/TIBServer component and for the
669 entered value to be saved on a project specific basis (design time only).
670
671 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
672 column fieldname. If they are the same then it is acts as a look up for the KeyValue
673 Otherwise, it sets the column text to the selected ListField Value.
674
675 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
676 column width.
677
678 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
679 and a case insensitive search is requested.
680
681 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
682 or column ListSource.
683
684 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
685 unprepare) when closing and the text has not changed.
686
687 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
688 Less likely to cause a cursor re-use error on Windows.
689
690 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
691 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
692
693 11. TIBTreeView: Guard against nil destination on record changed
694
695 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
696 string type with the code page set to reflect the returned field encoding after
697 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
698 earlier versions.
699
700 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
701 will now result in transliteration to the code page specified for the Firebird driver
702 if the assigned string has a different code page. FPC 3.0.0 onwards only.
703
704 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
705 is ignored and the lc_ctype value, when the database is opened, is set to align with
706 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
707 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
708 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
709 the GETACP is used to determine the Windows code page.
710
711 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
712 name used as the lc_ctype when the database was opened. Only valid while the
713 Database is connected.
714
715 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
716 id that corresponds to the DefaultCharSetName.
717
718 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
719
720 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
721 path is given and database attach fails due to access permission issues on the
722 temp directory or security database, then the attach is retried with "localhost:"
723 prefixing the databasename. This should avoid problems when the database has to
724 be accessed by a local (e.g. classic) server and libfbembed is used.
725
726 2. Windows: revised search order for Firebird DLL:
727 i. The Firebird Embedded Server in the application Directory.
728 ii. If the FIREBIRD environment variable is set then the directory this
729 points to is searched for the FB Client DLL and then then underlying
730 "bin" directory.
731 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
732 is used to locate the Firebird installation directory and the underlying
733 "bin" directory is searched for the FB Client DLL.
734 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
735 are searched for the FB Client DLL.
736 v. The PATH Environment variable is used to search for the FB Client DLL.
737 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
738
739 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
740 See doc/readme.scriptengine and example applications.
741
742 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
743 simplify the use of the embedded firebird server on both Linux and Windows platforms.
744 See dpc/readme.localdatabase and example applications.
745
746 5. IBDynamicGrid: Reordering on column header click should now also work for
747 dynamic columns.
748
749 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
750 between incrementing/decrementing the lock count and signalling the event.
751
752 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
753
754 1.3.2 was never formally released and only made available as beta copies.
755
756 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
757
758 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
759
760 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
761
762 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
763 i.e. when it is a calculated field
764
765 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
766 This problem was due to a race condition between recalculating row heights and
767 determining which row was selected by the mouse click. The row height calculation
768 is now deferred by an extra trip round the message loop allowing the row to
769 be always calculated on the current grid layout rather than risking it being
770 calculated on the grid layout after the expanded row has been shrunk.
771
772 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
773 Windows.
774
775 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
776 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
777 to be determined at runtime. See doc/readme.charactersets.html.
778
779 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
780 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
781
782 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
783 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
784 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
785
786 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
787 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
788 implies no truncation.
789
790 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
791
792 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
793 (avoids "Not in Edit Mode" error).
794
795 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
796
797 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
798 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
799
800 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
801
802 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
803
804 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
805
806 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
807
808 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
809
810 1. OnCloseUp Event Handler added to TDBLookupProperties
811
812 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
813 problem with row size when exception is called.
814
815 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
816
817 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
818 in a TCustomComboBox and ignores return key if in a TCustomMemo
819
820 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
821 keyed in i.e. when autocomplete not performed
822
823 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
824 console mode applications with all LCL required functions (builtin dialogs and
825 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
826 not included in your project, IBX should compile and link with a console mode program.
827 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
828 console mode application or the IDE will automatically assume that your
829 application is GUI based. Instead, you should include the ibexpressconsolemode package.
830
831 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
832 to use the built in dialogs and cursor management. IBDialogs is
833 included by default if "ibexpress" is in your project source's "uses" clause.
834 This should be the case for all projects created through the IDE. This is why
835 you do not want to add the ibexpress package to console mode applications. The
836 ibexpressconsolemode package has been created to allow console mode programs
837 to avoid adding LCL dependencies when using IBX, while still having the
838 unit search paths set up correctly.
839
840 Existing users should check to ensure that the "ibexpress" unit is included in
841 each project's source file (*.lpr).
842
843 You may find that in order for the IDE to recognise that ibexpressconsolemode
844 exists, you have to first open the package in the IDE and then close it. This
845 adds it to the most recently accessed packages list. To make it permanently
846 available, add the package name to lazarus' staticpackages.inc file.
847
848 Thanks to Julio Jiménez for suggesting support of console mode.
849
850 7. SQL Parser can now accept quoted strings that include new lines
851
852 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
853 of text on start of edit. This is particularly useful when tabbing to a
854 column and then inserting text.
855
856 9. New Examples provided for IB Services and ISQLMonitor.
857
858 10. Fix error when writing to blob streams that recorded only the last buffer
859 write in the blob stream. In most cases, this did not cause a problem as the
860 IB Blob Stream is written in a single write. However, with the TDBImage, write
861 of a graphic type prefix was lost which caused a problem when the image could
862 not be automatically recognised.
863
864 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
865 already open" errors due to random numbers used for the cursor name being identical.
866
867 12. IBTable: corrected error that could result in an "Index out of bounds" error
868 when opening the table and the Primary Key is the last or only column in the
869 table. Thanks to Rick Hoover for the fix.
870
871 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
872 of "UTF-8", and update list of available database character sets. Existing
873 users should check the current lc_ctype setting in their applications.
874
875 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
876
877 1. Firebird Services: avoid List Index error when opening a service with an
878 empty Params property.
879
880 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
881 Link now set up in Loaded method - avoids occasional failure to apply
882 SQL markup on initial open.
883
884 3. "Employees" example performance improvements when scrolling.
885
886 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
887 TFrame. Force recaching of selected frame to avoid GTK race (results in a
888 random image cached).
889
890 5. DBControlGrid: Should now react to changes in panel height at run time.
891
892 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
893 even when further rows exist.
894
895 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
896 always be derived from panel height and setting this property can cause confusion.
897 Note for existing projects: to avoid a missing property error at run time,
898 each form using the DBControlGrid must be opened, updated and saved in the IDE
899 in order to remove the property value from the lfm.
900
901
902 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
903
904 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
905 call Prepare before setting parameter values.
906
907 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
908
909 3. Code tidyup and more robust handling of dsql information result vector.
910
911 4. Support for centralised handling of transaction status changes. TIBTransaction
912 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
913 and "AfterExecQuery". The first three are called after the same event is called
914 for an IBCustomDataSet descendent using the Transaction. The fourth is called
915 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
916 enable monitoring of transaction status changes for a given transaction to be
917 handled in a single place. For example, when a change to the dataset occurs
918 an indicator can be set that shows the user that in order to save changes,
919 the transaction should be committed. Rather than doing this per dataset, this
920 can now be done per transaction.
921
922 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
923 the dataset is scrolled. However, any changes to the current row are, by default,
924 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
925 have a new property "DataSetCloseAction" that adds automatic posting of changes
926 on dataset close. If this property is set to dcDiscardChanges (default) then the
927 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
928 then IBX will attempt to post any unsaved changes before the dataset is closed
929 (and after the BeforeClose event handler is called). The exception is when the
930 dataset is being closed as a result of a transaction rollback. In this case,
931 no action is taken and any unsaved changes are discarded. This avoids both
932 unnecessary overhead and the risk that a validation error may occur in the Post
933 raising an exception and thereby preventing a rollback.
934
935 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
936 In earlier versions, the Display Width was set to the maximum byte width rather than the character
937 width. Display Widths are now corrected by dividing by the max byte width per character.
938 For UTF8 character sets, the byte width is four and hence the Display Width will be
939 the byte width divided by 4. The byte width of each character set is determined
940 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
941 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
942
943 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
944
945 8. IBLookupComboEditBox: List should now always be restored to full list when the
946 control loses focus. Default Key press default interval reduced to 200ms.
947
948 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
949 when dataset rows are less than visible rows.
950
951 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
952 does not exist or DataSet is empty. More responsive on dataset open. New event
953 OnRestorePosition. Column sort disabled if no header row.
954
955 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
956 while dataset state is dsInsert. Avoids posting errors.
957
958 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
959 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
960
961 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
962
963 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
964 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
965 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
966 always "posts" the current record regardless or whether or not it may be more appropriate
967 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
968 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
969 as the first action of the "Post" method and allows the handler to convert the Post
970 into a Cancel if that is the appropriate action on moving to a different row. This is
971 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
972 raised here, but it may still be more appropriate to validate a post and signal
973 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
974
975 15. On Unix derived systems, the Firebird library name can now be given as a colon
976 separated list. Each library name on the list is tried in turn, in left to right
977 order with the first found being used as the firebird library. By default, on Linux,
978 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
979 overidden by the FBLIB environment variable or the OnGetLibraryName function.
980
981 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
982 then it will still attempt to access the database via the Firebird Server and will
983 require a username and password. If only the pathname is given, then the username
984 and password should be omitted and the unix file permissions are used to grant
985 access.
986
987 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
988
989 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
990 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
991 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
992 corresponds to a row of the linked DataSource. Any data aware control on the
993 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
994
995 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
996 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
997 takes place during database access. This may be useful when there are performance issues with
998 the change of cursor. Setting the property to false suppresses the change of cursor.
999
1000 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1001 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1002 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1003 making all changes permanent immediately rather than when the transaction is explicitly
1004 committed.
1005
1006 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1007 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1010
1011 Development version only.
1012
1013 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1014
1015 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1016 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1017 "Where" and "Having" clauses to implement user specified filters of arbitrary
1018 complexity.
1019
1020 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1021 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1022 These are:
1023
1024 - TIBLookupComboEditBox
1025 - TIBDynamicGrid
1026 - TIBTreeview
1027
1028 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1029 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1030 to revise the available list and restrict it to items that are prefixed by the
1031 typed text (either case sensitive or case insensitive). Autoinsert allows a
1032 newly typed entry to be added to the list dataset and included in the available
1033 list items.
1034
1035 TIBDynamicGrid is a TDBGrid descendent that provides for:
1036 - automatic resizing of selected columns to fill the available row length
1037 - automatic positioning and sizing of a "totals" control, typically at the
1038 column footer, on a per column basis.
1039 - DataSet resorting on header row click, sorting the dataset by the selected column.
1040 A second click on the same header cell reversed the sort order.
1041 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1042 is automatically expanded and a panel superimposed on it. The panel can have any
1043 number of child controls, typically data aware controls with the same datasource
1044 as the grid allowing for editing of additional fields and more complex editors.
1045 - Reselection of the same row following resorting.
1046 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1047 Its properties are specified on a per column basis and allows for one or more
1048 columns to have their values selected from a list provided by a dataset.
1049 Autocomplete and autoinsert are also available. The existing picklist editor
1050 is unaffected by the extension.
1051
1052 TIBTreeView is a data aware TCustomTreeView.
1053
1054 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1055 zero scale will no longer return an error. An Int64 will be returned instead.
1056
1057 4. TIBTransaction now has events for Before and After Transaction End and a new function
1058 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1059
1060 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1061 repeated multiple times.
1062
1063 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1064 check used to get in the way of using Stored Procedures, and "Update or Insert"
1065 statements.
1066
1067 7. Insert, Modify and Delete property Editors now support Query Generation from
1068 Stored Procedures.
1069
1070 8. Three new examples illustrate the use of the new IB Controls
1071
1072
1073 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1074
1075 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1076 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1077 Gabor Boros for reporting this problem and for testing the improvements).
1078
1079 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1080 See readme.field+param.names in the doc folder.
1081
1082 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1083 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1084
1085 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1086
1087 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1088 actions.
1089
1090 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1091 thanks to Yuriy Kopnin for pointing this out).
1092
1093 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1094
1095 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1096 for both fields and parameter setting.
1097
1098 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1099 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1100
1101 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1102 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1103
1104 11. TIBTable now has a property editor for "MasterFields"
1105
1106 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1107 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1108
1109 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1110 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1111
1112
1113 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1114
1115 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1116
1117 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1118
1119 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1120 it is null. This allows for alternative user defined setting of the generator
1121
1122 Many thanks to Julio Jiménez for this fix
1123
1124 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1125 and suggests that the user may have forgotten to install it.
1126
1127 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1128
1129 1. Conditional compilation used to limit registration of TIntegerField to
1130 Lazarus versions less than 1.1
1131
1132 2. When a database connection is created, character set is now by default set
1133 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1134 1250 to 1254.
1135
1136
1137 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1138
1139 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1140
1141
1142 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1143
1144 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1145 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1146
1147 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1148 package is changed to do this (which it should do).
1149
1150 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1151
1152 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1153
1154 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1155
1156 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1157
1158 4. Property editors should now correctly resize.
1159
1160 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1161 (restored original functionality)
1162
1163 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1164 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
