1 + IBX Change Log  version        (2.3-0) Mon, 19 Mar 2018 09:45:35 +0000
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 deLaoutChanged 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. 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. TIBExtact: Package Headers and Package Bodies are now included in the extracted
107 +    DDL (Firebird 3 and later only).
108 +
109 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
110 +
111 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
112 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
113 + RELEASE.
114 +
115 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
116 +
117 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
118 +
119 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
120 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
121 +   information). However, this is also a very useful mechanism for returning updated computed by
122 +   column values. Values returned as a result of executing an Insert or Update statement
123 +   replace existing values in the current row for each corresponding column.
124 +
125 +   Previously, if a dataset's select query included read only (computed by) fields then
126 +   an automatic row refresh was performed after an insert or update query had been processed,
127 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
128 +   that an automatic refresh is no longer performed if an insert or update query contains
129 +   a returning clause that updates one or more fields on the current row. A full row
130 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
131 +   field values and the select query contains read only fields. Use of Insert/update
132 +   returning should be significantly more efficient than executing a refresh query.
133 +
134 +   This behaviour change is intended to be backwards compatible and there should be no need to change
135 +   existing programs, other than to improve performance by using the new capability.
136 +
137 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
138 +   they are called when the dataset row is being deleted, there is no value in
139 +   updating the current record from the query result. Instead, a new event handler
140 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
141 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
142 +   by the query. The event handler can then interrogate the query results and
143 +   perform whatever action is necessary. For example to confirm, to the user,
144 +   the deletion of a row with the returned values.
145 +
146 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
147 +   any Computed By or Identity Columns. The IBTables example has been updated to
148 +   illustrate the computation of the employee Full Name on update.
149 +
150 + 5. TIBTable: The GeneratorField property is now published.
151 +
152 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
153 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
154 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
155 +   each Identity column after the insert is executed.
156 +
157 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
158 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
159 +   Insert..Returning clause.
160 +
161 + 8. TIBGenerator: small performance improvement by not preparing query each time
162 +   a new value is generated.
163 +
164 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
165 +
166 + 10. Property editors will now sync table name to a System Table when "Include System
167 +    Tables" is selected and the query is for a System Table.
168 +
169 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
170 +    values are no longer converted to milliseconds from TDateTime and then back again
171 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
172 +
173 + 12. Property Editors handling of Stored Procedures.
174 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
175 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
176 +      query).
177 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
178 +
179 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
180 +    can be used to select a package. If non-empty, the stored procedure name is
181 +    expected to be a stored procedure defined in the specified package and the
182 +    generated SQL will be as required for a stored procedure located in a package.
183 +
184 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
185 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
186 +    which a stored procedure can be selected. With no package name selected, non-package
187 +    stored procedures are listed.
188 +
189 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
190 +    for password on reconnect.
191 +
192 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
193 +    and character set name.
194 +
195 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
196 +    DB info lookups"
197 +
198 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
199 +
200 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
201 +
202 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
203 +    parameters. This stops an exception being raised when the field cannot be
204 +    located in the record buffer.
205 +
206 + 21. Property Editors now automatically include System Tables when opened and when the query table
207 +    is a System Table.
208 +
209 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
210 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
211 +
212 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
213 +    add the SPB item isc_spb_expected_db. This names a database using
214 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
215 +    database. examples/services re-written to illustrate use of "expected_db".
216 +
217 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
218 +    This avoids truncated backups when the server returns a timeout (busy) response.
219 +
220 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
221 +
222 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
223 +    databasenames. These are respectively expanded to the local system's temp directory
224 +    (including trailing delimiter) or to a prescribed data directory (including
225 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
226 +    in the user's home directory. The hidden directory name is either the string returned
227 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
228 +    Under Windows, the directory is the same as the Data Directory as decribed
229 +    above but instead prefixed by the User's application data path. These may be
230 +    used to improve application portability for Personal Databases.
231 +
232 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
233 +    this has not worked for a long time and is not useful either. FieldDefs should be
234 +    managed using the Fields Editor as with any other dataset. To access the fields
235 +    editor for a TIBTable component, double click on the component. The fields editor
236 +    is then displayed.
237 +
238 + 28. TIBDatabaseInfo: new properties/function
239 +     * DateDBCreated (returns date/time database created)
240 +     * TransactionCount (returns no. of active transactions)
241 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
242 +     * PagesFree (Firebird 3 or later)
243 +     * PagesUsed (Firebird 3 or later)
244 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
245 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
246 +
247 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
248 +
249 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
250 +
251 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
252 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
253 +
254 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
255 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
256 +    firing during backup and restore.
257 +
258 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
259 +    for verbose output using the new property "StatisticsRequested".
260 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
261 +
262 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
263 +
264 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
265 +    palette. This uses the online validation feature added in Firebird 2.5. The
266 +    services's properties enable inclusion/exclusion of tables and indexes using
267 +    regular expressions. See.
268 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
269 +
270 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
271 +    option on a database.
272 +
273 + 37. TIBCustomService: Assign method implemented to allow copying of service login
274 +    context between service API components. "Detach" method now only detaches
275 +    service when last reference to the service interface detaches. Tidy up of
276 +    code for SetActive and Attach methods including password hiding.
277 +
278 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
279 +    and used to determine the auth method and protocol used for the connection.
280 +
281 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
282 +    a Create Database Statement generated by IBX.
283 +
284 + 40. All IBServices now have an additional published property "PortNo". This may
285 +    be set to a non-standard port number when necessary. If zero then the default
286 +    port number is used.
287 +
288 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
289 +    and not just the mouse.
290 +
291 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
292 +
293 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
294 +    image index and selected image index for each node to be set from a database field.
295 +
296 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
297 +    then database schema includes grants to all users. If not present then the
298 +    only user grants included are those to User PUBLIC.
299 +
300 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
301 +    and child nodes in dataset.
302 +
303 +
304 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
305 +
306 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
307 +   changes.
308 +
309 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
310 +   Bug could result in truncated multi-byte character set values.
311 +
312 + 3. Changes consequential on moving fbintf character set utility functions from
313 +   IFirebirdAPI to IAttachment.
314 +
315 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
316 +
317 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
318 +   results in autocomplete ignoring prefix text.
319 +
320 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
321 +   entering a new name into the text box.
322 +
323 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
324 +   Firebird rather than recomputing it.
325 +
326 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
327 +   screen centre. Previously some were "poDesigned" which may be inappropriate
328 +   for multi monitor desktops.
329 +
330 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
331 +
332 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
333 +    a transaction and always reset the object.
334 +
335 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
336 +
337 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
338 +
339 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
340 +    to a gbak format archive.
341 +
342 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
343 +
344 + 16. IBLocaldb: Drop database if error creating an empty database.
345 +
346 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
347 +    unless selected node not in current dataset.
348 +
349 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
350 +    to TIBCustomService, and IBlocalDB code tidy up.
351 +
352 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
353 +    behaviour due to uninitialised variable.
354 +
355 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
356 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
357 +
358 + 21. IBSQL: When Database changed ensure that all resources are freed.
359 +
360 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
361 +
362 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
363 +    * Line Wrap on SQL Token boundaries (on user command)
364 +    * auto-complete table names in drop down list of table names
365 +    * Double click on tablename or field name adds to SQL text
366 +
367 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
368 +
369 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
370 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
371 +    workaround for a problem in fpc 3.0.4 win64).
372 +
373 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
374 +
375 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
376 +
377 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
378 +
379 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
380 +   include remote system name.
381 +
382 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
383 +   tables when data included in output.
384 +
385 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
386 +   and timing information to be written to stdout. This may be used to locate
387 +   performance bottlenecks.
388 +
389 + 4. SQLParser: only call "OnChanging" event handler when value is different.
390 +
391 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
392 +
393 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
394 +   that BindFields is called when the query is next activated. Avoids FieldName
395 +   not found error.
396 +
397 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
398 +   purpose and allows the programmer to define any action they want for Update, Insert
399 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
400 +   filtering of updates, or use of statements such as Grant or Revoke instead of
401 +   normal DML. See User Manual for more information.
402 +
403 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
404 +
405 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
406 +
407 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
408 +
409 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
410 +   hexadecimal notation.
411 +
412 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
413 +   using a simple XML format.
414 +
415 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
416 +   grants to these objects.
417 +
418 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
419 +   dependency problems restoring complex databases.
420 +
421 + 7. TIBXScript: This component has been restructured to allow for the processing of
422 +   embedded XML in INSERT statements and to support interactive sources in addition
423 +   to non-interactive data sources such as files.
424 +
425 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
426 +
427 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
428 +   SET SQL DIALECT
429 +   SET TERM
430 +   SET AUTODDL
431 +   SET BAIL
432 +   SET ECHO
433 +   SET COUNT
434 +   SET STATS
435 +   SET NAMES <character set>
436 +
437 + 10. IBVersion unit added to hold current IBX Version Number information.
438 +
439 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
440 +    and domain definitions.
441 +
442 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
443 +    fully supported.
444 +
445 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
446 +
447 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
448 +
449 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
450 +
451 + See also doc/IBX4LazarusGuide.pdf for important information on
452 + upgrading to IBX2.
453 +
454 + 1. Size property of TIBStringField is now the width in characters of the field
455 +   and not the byte length. This applies only to multi-byte character sets such
456 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
457 +   code is not recognised as a bug and hence this change to align the behaviour.
458 +   The TStringField change is expected in fpc 3.2.0.
459 +
460 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
461 +   true (default) then Size property value saved in the lfm is ignored. Size is
462 +   always set from the dynamic information read from the database. It is unclear
463 +   why anyone would want to override this and set Size to false.
464 +
465 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
466 +   block.
467 +
468 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
469 +   exist when an attempt is made to connect to it (run time only) then an attempt
470 +   is made to create the database.
471 +
472 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
473 +   has been successfully created as a result of a call to CreateDatabase or when
474 +   creating a database after it was found not to exist.
475 +
476 + 6.  DBControlGrid: a race condition could result in the wrong row image being
477 +    written to the cache. This has been avoided by a trip round the message
478 +    loop before rendering the row image.
479 +
480 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
481 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
482 +    known to risk corrupt rendering of row images when the control is first
483 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
484 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
485 +
486 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
487 +    a TDateEdit control located on an editor panel.
488 +
489 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
490 +
491 + 10. DBControlGrid: Removed memory leak when updating rows.
492 +
493 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
494 +
495 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
496 +
497 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
498 +   when target codepage is CP_NONE. This is a workaround for
499 +   http://bugs.freepascal.org/view.php?id=30622.
500 +
501 + 2. DBLog option removed from TIBStatisticalService - not supported by server
502 +   since Firebird 1.5.
503 +
504 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
505 +   similar.
506 +
507 + 4. IBCodePage: updated mapping between codepages and character id.
508 +
509 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
510 +   Firebird. Character sets with a char width of two are not UTF16.
511 +
512 + 6. Strings received from the database are now always transliterated into UTF8
513 +   regardless of the database character set or connection character set. This
514 +   is for compatibility with the LCL.
515 +
516 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
517 +
518 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
519 +   read in an entire blob just to get the size of the blob. General performance
520 +   improvement when opening datasets containing blobs.
521 +
522 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
523 +
524 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
525 +   is now used.
526 +
527 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
528 +   determined.
529 +
530 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
531 +
532 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
533 +   lazarus 1.6.0
534 +
535 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
536 +   compilation error.
537 +
538 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
539 +
540 + 1. No character set specified for connection: when a text blob is retrieved, the
541 +  character set is determined by looking up the native character set using then
542 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
543 +  set as the connection.
544 +
545 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
546 +   for Login Dialog returing a change to the database path.
547 +
548 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
549 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
550 +   entered value to be saved on a project specific basis (design time only).
551 +
552 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
553 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
554 +   Otherwise, it sets the column text to the selected ListField Value.
555 +
556 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
557 +   column width.
558 +
559 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
560 +   and a case insensitive search is requested.
561 +
562 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
563 +   or column ListSource.
564 +
565 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
566 +   unprepare) when closing and the text has not changed.
567 +
568 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
569 +   Less likely to cause a cursor re-use error on Windows.
570 +
571 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
572 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
573 +
574 + 11. TIBTreeView: Guard against nil destination on record changed
575 +
576 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
577 +    string type with the code page set to reflect the returned field encoding after
578 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
579 +    earlier versions.
580 +
581 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
582 +    will now result in transliteration to the code page specified for the Firebird driver
583 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
584 +
585 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
586 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
587 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
588 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
589 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
590 +    the GETACP is used to determine the Windows code page.
591 +
592 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
593 +    name used as the lc_ctype when the database was opened. Only valid while the
594 +    Database is connected.
595 +
596 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
597 +    id that corresponds to the DefaultCharSetName.
598 +
599 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
600 +
601 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
602 +   path is given and database attach fails due to access permission issues on the
603 +   temp directory or security database, then the attach is retried with "localhost:"
604 +   prefixing the databasename. This should avoid problems when the database has to
605 +   be accessed by a local (e.g. classic) server and libfbembed is used.
606 +
607 + 2. Windows: revised search order for Firebird DLL:
608 +     i.   The Firebird Embedded Server in the application Directory.
609 +     ii.  If the FIREBIRD environment variable is set then the directory this
610 +          points to is searched for the FB Client DLL and then then underlying
611 +          "bin" directory.
612 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
613 +          is used to locate the Firebird installation directory and the underlying
614 +          "bin" directory is searched for the FB Client DLL.
615 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
616 +          are searched for the FB Client DLL.
617 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
618 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
619 +
620 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
621 +   See doc/readme.scriptengine and example applications.
622 +
623 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
624 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
625 +   See dpc/readme.localdatabase and example applications.
626 +
627 + 5. IBDynamicGrid: Reordering on column header click should now also work for
628 +   dynamic columns.
629 +
630 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
631 +   between incrementing/decrementing the lock count and signalling the event.
632 +
633 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
634 +
635 + 1.3.2 was never formally released and only made available as beta copies.
636 +
637 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
638 +
639 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
640 +
641 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
642 +
643 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
644 +   i.e. when it is a calculated field
645 +
646 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
647 +   This problem was due to a race condition between recalculating row heights and
648 +   determining which row was selected by the mouse click. The row height calculation
649 +   is now deferred by an extra trip round the message loop allowing the row to
650 +   be always calculated on the current grid layout rather than risking it being
651 +   calculated on the grid layout after the expanded row has been shrunk.
652 +
653 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
654 +   Windows.
655 +
656 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
657 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
658 +   to be determined at runtime. See doc/readme.charactersets.html.
659 +
660 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
661 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
662 +
663 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
664 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
665 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
666 +
667 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
668 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
669 +   implies no truncation.
670 +
671 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
672 +
673 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
674 +   (avoids "Not in Edit Mode" error).
675 +
676 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
677 +
678 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
679 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
680 +
681 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
682 +
683 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
684 +
685 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
686 +
687 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
688 +
