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

895 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
896 +
897 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
898 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
899 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
900 +    corresponds to a row of the linked DataSource. Any data aware control on the
901 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
902 +
903 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
904 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
905 +   takes place during database access. This may be useful when there are performance issues with
906 +   the change of cursor. Setting the property to false suppresses the change of cursor.
907 +
908 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
909 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
910 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
911 +   making all changes permanent immediately rather than when the transaction is explicitly
912 +   committed.
913 +
914 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
915 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

921 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
922 +
923 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
924 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
925 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
926 +   complexity.
927 +
928 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
929 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
930 +   These are:
931 +
932 +   - TIBLookupComboEditBox
933 +   - TIBDynamicGrid
934 +   - TIBTreeview
935 +
936 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
937 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
938 +   to revise the available list and restrict it to items that are prefixed by the
939 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
940 +   newly typed entry to be added to the list dataset and included in the available
941 +   list items.
942 +
943 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
944 +   - automatic resizing of selected columns to fill the available row length
945 +   - automatic positioning and sizing of a "totals" control, typically at the
946 +     column footer, on a per column basis.
947 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
948 +     A second click on the same header cell reversed the sort order.
949 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
950 +     is automatically expanded and a panel superimposed on it. The panel can have any
951 +     number of child controls, typically data aware controls with the same datasource
952 +     as the grid allowing for editing of additional fields and more complex editors.
953 +   - Reselection of the same row following resorting.
954 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
955 +     Its properties are specified on a per column basis and allows for one or more
956 +     columns to have their values selected from a list provided by a dataset.
957 +     Autocomplete and autoinsert are also available. The existing picklist editor
958 +     is unaffected by the extension.
959 +
960 +   TIBTreeView is a data aware TCustomTreeView.
961 +
962 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
963 +   zero scale will no longer return an error. An Int64 will be returned instead.
964 +
965 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
966 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
967 +
968 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
969 +   repeated multiple times.
970 +
971 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
972 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
973 +   statements.
974 +
975 + 7. Insert, Modify and Delete property Editors now support Query Generation from
976 +   Stored Procedures.
977 +
978 + 8. Three new examples illustrate the use of the new IB Controls
979 +
980 +
981 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
982 +
983 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
984 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
985 +   Gabor Boros for reporting this problem and for testing the improvements).
986 +
987 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
988 +   See readme.field+param.names in the doc folder.
989 +
990 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
991 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
992 +
993 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
994 +
995 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
996 +   actions.
997 +
998 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
999 +   thanks to Yuriy Kopnin for pointing this out).
1000 +
1001 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1002 +
1003 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1004 +   for both fields and parameter setting.
1005 +
1006 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1007 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1008 +
1009 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1010 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1011 +
1012 + 11. TIBTable now has a property editor for "MasterFields"
1013 +
1014 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1015 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1016 +
1017 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1018 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
