1 + IBX Change Log  version               (2.3-0) Sat, 14 Apr 2018 16:47:40 +0100
2 +
3 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 + all previous copies of the IBX source code tree before installing this release.
5 +
6 + The IBX packages used by most users have not changed, with one exception. The
7 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 + to use the IBServices unit in your applications, please add the iblegacyServices
9 + to the list of dependencies. To do this, open the Project Inspector and select
10 + Add->New Requirement and select "ibLegacyServices" from the list of available
11 + packages.
12 +
13 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 +   the IBServices unit providing what is intended to be a clearer and easier to
15 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 +   more information and the guide to "Firebird Service Management Using IBX".
17 +   As indicated above, the legacy services components are still available and
18 +   provided in a separate package. There is no need to update working applications
19 +   using the older versions except for an additional package dependency.
20 +
21 + 2. The IBX packages and source code tree have been re-organised in an attempt to
22 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 +   new set of IBX packages.
25 +
26 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 +   updated to use the new Services API components.
28 +
29 + 4. The iblocal package has been updated to use the new Services API components.
30 +
31 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 +   TIBXSecurityService. It had been wrongly classified in the previous version
33 +   as a per database configuration item. It is global to a server and hence
34 +   correctly positioned as part of the Security Package. In the DBAdmin example,
35 +   the setting has moved to the mappings page.
36 +
37 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 +   are ignored.
39 +
40 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 +   closed before the database is dropped. Before and After Disconnect event handlers
42 +   are also fired.
43 +
44 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 +   is started and not just the first time.
46 +
47 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 +   depenendency with comp type.
49 +
50 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 +
52 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 +    then this is recognised and not ignored.
54 +
55 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 +
60 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 +    counters for the select query. Note: stats accumulate after each fetch from
63 +    the database. To get total query cost after open, call the "Last" method
64 +    and then GetPerfStatistics.
65 +
66 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 +
68 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 +    in parenthesises.
70 +
71 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 +    SQL identifiers are always delimited by double quotes. If false, then they are
73 +    only delimited if the identifier is a reserved word, contains lower case or special
74 +    characters. Set this property to true to retain previous behaviour.
75 +
76 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 +
79 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 +       property MasterDetailDelay: integer {defaults to zero}
81 +
82 +    When non-zero and the dataset is a detail table referencing a master table
83 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 +    then a synchronisation delay is added (in milliseconds) between the master
85 +    row changing and the detail dataset being re-opened. If the master dataset
86 +    is scrolled before the delay expires then the delay is reset. This can be used
87 +    to avoid performance overheads when scrolling through a large master dataset.
88 +
89 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 +    chreads unit must be included in your project. TTimer is not used in order
91 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 +
93 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 +    with Extract Option eoDatabase.
95 +
96 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 +    When a deLayoutChanged event is reported on the ListSource dataset, the
98 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 +    relationship with the control's datasource (master).
100 +
101 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102 +
103 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
105 +
106 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107 +    DDL (Firebird 3 and later only).
108 +
109 + 22. TIBLookupComboBox Autocomplete Fixes:
110 +    i. Only appended text is now selected after autocomplete.
111 +    ii. Uppercase keys no longer ignored for autocomplete.
112 +    iii. Retain Prefix case is now honoured correctly.
113 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114 +        before autocomplete performed. i.e. behaviour now the same as when
115 +        no DataSource assigned.
116 +
117 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 +    between SQL statements.
119 +
120 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121 +    ObjectNames are converted to upper case before matching against metadata object
122 +    names, unless the objectname is delimited by double quotes, in which case, the
123 +    double quotes are removed and the remaining string is used (unmodified) to match
124 +    against the metadata object name.
125 +
126 +    If true then the ObjectName is used as is without modification and matched
127 +    against the metadata object name. No attempt is made to remove double quotes.
128 +
129 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130 +    with eoTrigger, these extract types can be used to select only Database Triggers,
131 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132 +
133 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
134 +    statement separate character is now reset to the default (';').
135 +
136 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
137 +
138 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
139 +    a commit or reconnect statement and instead activated only when next SQL statement
140 +    is executed.
141 +
142 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
143 +
144 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
145 +    converting statement to upper case.
146 +
147 + 31. TIBExtract: metadata comments now supported. New published property
148 +    IncludeMetaDataComments (default true). If true then metadata comments included
149 +    in extracted DDL. New Extract Object member eoComments. This may be used with
150 +    ExtractObject method to list all metadata comments.
151 +
152 + 32. TIBExtract: ListObjectNames method added.
153 +
154 + 33. Updated Database component editor to support additional connection string
155 +    types.
156 +
157 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
158 +
159 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
160 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
161 + RELEASE.
162 +
163 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
164 +
165 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
166 +
167 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
168 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
169 +   information). However, this is also a very useful mechanism for returning updated computed by
170 +   column values. Values returned as a result of executing an Insert or Update statement
171 +   replace existing values in the current row for each corresponding column.
172 +
173 +   Previously, if a dataset's select query included read only (computed by) fields then
174 +   an automatic row refresh was performed after an insert or update query had been processed,
175 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
176 +   that an automatic refresh is no longer performed if an insert or update query contains
177 +   a returning clause that updates one or more fields on the current row. A full row
178 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
179 +   field values and the select query contains read only fields. Use of Insert/update
180 +   returning should be significantly more efficient than executing a refresh query.
181 +
182 +   This behaviour change is intended to be backwards compatible and there should be no need to change
183 +   existing programs, other than to improve performance by using the new capability.
184 +
185 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
186 +   they are called when the dataset row is being deleted, there is no value in
187 +   updating the current record from the query result. Instead, a new event handler
188 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
189 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
190 +   by the query. The event handler can then interrogate the query results and
191 +   perform whatever action is necessary. For example to confirm, to the user,
192 +   the deletion of a row with the returned values.
193 +
194 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
195 +   any Computed By or Identity Columns. The IBTables example has been updated to
196 +   illustrate the computation of the employee Full Name on update.
197 +
198 + 5. TIBTable: The GeneratorField property is now published.
199 +
200 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
201 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
202 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
203 +   each Identity column after the insert is executed.
204 +
205 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
206 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
207 +   Insert..Returning clause.
208 +
209 + 8. TIBGenerator: small performance improvement by not preparing query each time
210 +   a new value is generated.
211 +
212 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
213 +
214 + 10. Property editors will now sync table name to a System Table when "Include System
215 +    Tables" is selected and the query is for a System Table.
216 +
217 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
218 +    values are no longer converted to milliseconds from TDateTime and then back again
219 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
220 +
221 + 12. Property Editors handling of Stored Procedures.
222 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
223 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
224 +      query).
225 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
226 +
227 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
228 +    can be used to select a package. If non-empty, the stored procedure name is
229 +    expected to be a stored procedure defined in the specified package and the
230 +    generated SQL will be as required for a stored procedure located in a package.
231 +
232 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
233 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
234 +    which a stored procedure can be selected. With no package name selected, non-package
235 +    stored procedures are listed.
236 +
237 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
238 +    for password on reconnect.
239 +
240 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
241 +    and character set name.
242 +
243 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
244 +    DB info lookups"
245 +
246 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
247 +
248 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
249 +
250 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
251 +    parameters. This stops an exception being raised when the field cannot be
252 +    located in the record buffer.
253 +
254 + 21. Property Editors now automatically include System Tables when opened and when the query table
255 +    is a System Table.
256 +
257 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
258 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
259 +
260 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
261 +    add the SPB item isc_spb_expected_db. This names a database using
262 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
263 +    database. examples/services re-written to illustrate use of "expected_db".
264 +
265 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
266 +    This avoids truncated backups when the server returns a timeout (busy) response.
267 +
268 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
269 +
270 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
271 +    databasenames. These are respectively expanded to the local system's temp directory
272 +    (including trailing delimiter) or to a prescribed data directory (including
273 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
274 +    in the user's home directory. The hidden directory name is either the string returned
275 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
276 +    Under Windows, the directory is the same as the Data Directory as decribed
277 +    above but instead prefixed by the User's application data path. These may be
278 +    used to improve application portability for Personal Databases.
279 +
280 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
281 +    this has not worked for a long time and is not useful either. FieldDefs should be
282 +    managed using the Fields Editor as with any other dataset. To access the fields
283 +    editor for a TIBTable component, double click on the component. The fields editor
284 +    is then displayed.
285 +
286 + 28. TIBDatabaseInfo: new properties/function
287 +     * DateDBCreated (returns date/time database created)
288 +     * TransactionCount (returns no. of active transactions)
289 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
290 +     * PagesFree (Firebird 3 or later)
291 +     * PagesUsed (Firebird 3 or later)
292 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
293 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
294 +
295 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
296 +
297 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
298 +
299 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
300 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
301 +
302 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
303 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
304 +    firing during backup and restore.
305 +
306 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
307 +    for verbose output using the new property "StatisticsRequested".
308 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
309 +
310 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
311 +
312 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
313 +    palette. This uses the online validation feature added in Firebird 2.5. The
314 +    services's properties enable inclusion/exclusion of tables and indexes using
315 +    regular expressions. See.
316 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
317 +
318 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
319 +    option on a database.
320 +
321 + 37. TIBCustomService: Assign method implemented to allow copying of service login
322 +    context between service API components. "Detach" method now only detaches
323 +    service when last reference to the service interface detaches. Tidy up of
324 +    code for SetActive and Attach methods including password hiding.
325 +
326 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
327 +    and used to determine the auth method and protocol used for the connection.
328 +
329 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
330 +    a Create Database Statement generated by IBX.
331 +
332 + 40. All IBServices now have an additional published property "PortNo". This may
333 +    be set to a non-standard port number when necessary. If zero then the default
334 +    port number is used.
335 +
336 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
337 +    and not just the mouse.
338 +
339 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
340 +
341 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
342 +    image index and selected image index for each node to be set from a database field.
343 +
344 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
345 +    then database schema includes grants to all users. If not present then the
346 +    only user grants included are those to User PUBLIC.
347 +
348 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
349 +    and child nodes in dataset.
350 +
351 +
352 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
353 +
354 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
355 +   changes.
356 +
357 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
358 +   Bug could result in truncated multi-byte character set values.
359 +
360 + 3. Changes consequential on moving fbintf character set utility functions from
361 +   IFirebirdAPI to IAttachment.
362 +
363 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
364 +
365 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
366 +   results in autocomplete ignoring prefix text.
367 +
368 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
369 +   entering a new name into the text box.
370 +
371 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
372 +   Firebird rather than recomputing it.
373 +
374 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
375 +   screen centre. Previously some were "poDesigned" which may be inappropriate
376 +   for multi monitor desktops.
377 +
378 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
379 +
380 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
381 +    a transaction and always reset the object.
382 +
383 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
384 +
385 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
386 +
387 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
388 +    to a gbak format archive.
389 +
390 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
391 +
392 + 16. IBLocaldb: Drop database if error creating an empty database.
393 +
394 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
395 +    unless selected node not in current dataset.
396 +
397 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
398 +    to TIBCustomService, and IBlocalDB code tidy up.
399 +
400 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
401 +    behaviour due to uninitialised variable.
402 +
403 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
404 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
405 +
406 + 21. IBSQL: When Database changed ensure that all resources are freed.
407 +
408 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
409 +
410 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
411 +    * Line Wrap on SQL Token boundaries (on user command)
412 +    * auto-complete table names in drop down list of table names
413 +    * Double click on tablename or field name adds to SQL text
414 +
415 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
416 +
417 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
418 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
419 +    workaround for a problem in fpc 3.0.4 win64).
420 +
421 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
422 +
423 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

426 +
427 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
428 +   include remote system name.
429 +
430 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
431 +   tables when data included in output.
432 +
433 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
434 +   and timing information to be written to stdout. This may be used to locate
435 +   performance bottlenecks.
436 +
437 + 4. SQLParser: only call "OnChanging" event handler when value is different.
438 +
439 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
440 +
441 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
442 +   that BindFields is called when the query is next activated. Avoids FieldName
443 +   not found error.
444 +
445 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
446 +   purpose and allows the programmer to define any action they want for Update, Insert
447 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
448 +   filtering of updates, or use of statements such as Grant or Revoke instead of
449 +   normal DML. See User Manual for more information.

452 +
453 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
454 +
455 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
456 +
457 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
458 +   hexadecimal notation.
459 +
460 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
461 +   using a simple XML format.
462 +
463 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
464 +   grants to these objects.
465 +
466 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
467 +   dependency problems restoring complex databases.
468 +
469 + 7. TIBXScript: This component has been restructured to allow for the processing of
470 +   embedded XML in INSERT statements and to support interactive sources in addition
471 +   to non-interactive data sources such as files.
472 +
473 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
474 +
475 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
476 +   SET SQL DIALECT
477 +   SET TERM
478 +   SET AUTODDL
479 +   SET BAIL
480 +   SET ECHO
481 +   SET COUNT
482 +   SET STATS
483 +   SET NAMES <character set>
484 +
485 + 10. IBVersion unit added to hold current IBX Version Number information.
486 +
487 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
488 +    and domain definitions.
489 +
490 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
491 +    fully supported.
492 +
493 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
494 +
495 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

498 +
499 + See also doc/IBX4LazarusGuide.pdf for important information on
500 + upgrading to IBX2.
501 +
502 + 1. Size property of TIBStringField is now the width in characters of the field
503 +   and not the byte length. This applies only to multi-byte character sets such
504 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
505 +   code is not recognised as a bug and hence this change to align the behaviour.
506 +   The TStringField change is expected in fpc 3.2.0.
507 +
508 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
509 +   true (default) then Size property value saved in the lfm is ignored. Size is
510 +   always set from the dynamic information read from the database. It is unclear
511 +   why anyone would want to override this and set Size to false.
512 +
513 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
514 +   block.
515 +
516 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
517 +   exist when an attempt is made to connect to it (run time only) then an attempt
518 +   is made to create the database.
519 +
520 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
521 +   has been successfully created as a result of a call to CreateDatabase or when
522 +   creating a database after it was found not to exist.
523 +
524 + 6.  DBControlGrid: a race condition could result in the wrong row image being
525 +    written to the cache. This has been avoided by a trip round the message
526 +    loop before rendering the row image.
527 +
528 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
529 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
530 +    known to risk corrupt rendering of row images when the control is first
531 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
532 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
533 +
534 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
535 +    a TDateEdit control located on an editor panel.
536 +
537 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
538 +
539 + 10. DBControlGrid: Removed memory leak when updating rows.
540 +
541 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

543 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
544 +
545 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
546 +   when target codepage is CP_NONE. This is a workaround for
547 +   http://bugs.freepascal.org/view.php?id=30622.
548 +
549 + 2. DBLog option removed from TIBStatisticalService - not supported by server
550 +   since Firebird 1.5.
551 +
552 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
553 +   similar.
554 +
555 + 4. IBCodePage: updated mapping between codepages and character id.
556 +
557 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
558 +   Firebird. Character sets with a char width of two are not UTF16.
559 +
560 + 6. Strings received from the database are now always transliterated into UTF8
561 +   regardless of the database character set or connection character set. This
562 +   is for compatibility with the LCL.
563 +
564 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
565 +
566 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
567 +   read in an entire blob just to get the size of the blob. General performance
568 +   improvement when opening datasets containing blobs.
569 +
570 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
571 +
572 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
573 +   is now used.
574 +
575 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
576 +   determined.
577 +
578 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
579 +
580 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
581 +   lazarus 1.6.0
582 +
583 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
584 +   compilation error.
