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

426 >
427 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
428 >   tables when data included in output.
429 >
430 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
431 >   and timing information to be written to stdout. This may be used to locate

433 >
434 > 4. SQLParser: only call "OnChanging" event handler when value is different.
435 >
436 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
437 >
438 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures

441 >
442 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
443 >   purpose and allows the programmer to define any action they want for Update, Insert
444 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
445 >   filtering of updates, or use of statements such as Grant or Revoke instead of
446 >   normal DML. See User Manual for more information.

465 >
466 > 7. TIBXScript: This component has been restructured to allow for the processing of
467 >   embedded XML in INSERT statements and to support interactive sources in addition
468 >   to non-interactive data sources such as files.
469 >
470 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.

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

542 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
543 >   when target codepage is CP_NONE. This is a workaround for
544 >   http://bugs.freepascal.org/view.php?id=30622.
545 >
546 > 2. DBLog option removed from TIBStatisticalService - not supported by server
547 >   since Firebird 1.5.
548 >
549 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
550 >   similar.
551 >
552 > 4. IBCodePage: updated mapping between codepages and character id.
553 >
554 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
555 >   Firebird. Character sets with a char width of two are not UTF16.
556 >
557 > 6. Strings received from the database are now always transliterated into UTF8
558 >   regardless of the database character set or connection character set. This

562 >
563 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
564 >   read in an entire blob just to get the size of the blob. General performance
565 >   improvement when opening datasets containing blobs.
566 >
567 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
568 >
569 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
570 >   is now used.
571 >
572 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
573 >   determined.
574 >
575 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
576 >
577 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
578 >   lazarus 1.6.0

584 >
585 > 1. No character set specified for connection: when a text blob is retrieved, the
586 >  character set is determined by looking up the native character set using then
587 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
588 >  set as the connection.
589 >
590 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
591 >   for Login Dialog returing a change to the database path.
592 >
593 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
594 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
595 >   entered value to be saved on a project specific basis (design time only).
596 >
597 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
598 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
599 >   Otherwise, it sets the column text to the selected ListField Value.
600 >
601 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
602 >   column width.
603 >
604 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
605 >   and a case insensitive search is requested.
606 >
607 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
608 >   or column ListSource.
609 >
610 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
611 >   unprepare) when closing and the text has not changed.
612 >
613 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
614 >   Less likely to cause a cursor re-use error on Windows.
615 >
616 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
617 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
618 >
619 > 11. TIBTreeView: Guard against nil destination on record changed
620 >
621 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
622 >    string type with the code page set to reflect the returned field encoding after
623 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
624 >    earlier versions.
625 >
626 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
627 >    will now result in transliteration to the code page specified for the Firebird driver
628 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
629 >
630 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
631 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
632 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
633 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
634 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
635 >    the GETACP is used to determine the Windows code page.
636 >
637 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
638 >    name used as the lc_ctype when the database was opened. Only valid while the
639 >    Database is connected.
640 >
641 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
642 >    id that corresponds to the DefaultCharSetName.

646 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
647 >   path is given and database attach fails due to access permission issues on the
648 >   temp directory or security database, then the attach is retried with "localhost:"
649 >   prefixing the databasename. This should avoid problems when the database has to
650 >   be accessed by a local (e.g. classic) server and libfbembed is used.
651 >
652 > 2. Windows: revised search order for Firebird DLL:
653 >     i.   The Firebird Embedded Server in the application Directory.
654 >     ii.  If the FIREBIRD environment variable is set then the directory this
655 >          points to is searched for the FB Client DLL and then then underlying
656 >          "bin" directory.
657 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
658 >          is used to locate the Firebird installation directory and the underlying
659 >          "bin" directory is searched for the FB Client DLL.
660 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
661 >          are searched for the FB Client DLL.
662 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
663 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
664 >
665 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
666 >   See doc/readme.scriptengine and example applications.
667 >
668 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
669 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
670 >   See dpc/readme.localdatabase and example applications.
671 >
672 > 5. IBDynamicGrid: Reordering on column header click should now also work for
673 >   dynamic columns.
674 >
675 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
676 >   between incrementing/decrementing the lock count and signalling the event.

680 > 1.3.2 was never formally released and only made available as beta copies.
681 >
682 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
683 >
684 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
685 >
686 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
687 >
688 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
689 >   i.e. when it is a calculated field
690 >
691 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
692 >   This problem was due to a race condition between recalculating row heights and
693 >   determining which row was selected by the mouse click. The row height calculation
694 >   is now deferred by an extra trip round the message loop allowing the row to
695 >   be always calculated on the current grid layout rather than risking it being
696 >   calculated on the grid layout after the expanded row has been shrunk.
697 >
698 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
699 >   Windows.
700 >
701 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
702 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
703 >   to be determined at runtime. See doc/readme.charactersets.html.
704 >
705 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
706 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
707 >
708 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
709 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
710 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
711 >
712 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
713 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
714 >   implies no truncation.
715 >
716 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
717 >
718 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
719 >   (avoids "Not in Edit Mode" error).
720 >
721 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
722 >
723 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
724 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
725 >
726 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
727 >
728 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
729 >
730 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
731 >
732 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

735 >
736 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
737 >
738 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
739 >     problem with row size when exception is called.
740 >
741 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
742 >
743 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
744 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
745 >
746 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
747 >     keyed in i.e. when autocomplete not performed
748 >
749 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
750 >     console mode applications with all LCL required functions (builtin dialogs and
751 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
752 >     not included in your project, IBX should compile and link with a console mode program.
753 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
754 >     console mode application or the IDE will automatically assume that your
755 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
756 >
757 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
758 >     to use the built in dialogs and cursor management. IBDialogs is
759 >     included by default if "ibexpress" is in your project source's "uses" clause.
760 >     This should be the case for all projects created through the IDE. This is why
761 >     you do not want to add the ibexpress package to console mode applications. The
762 >     ibexpressconsolemode package has been created to allow console mode programs
763 >     to avoid adding LCL dependencies when using IBX, while still having the
764 >     unit search paths set up correctly.
765 >
766 >     Existing users should check to ensure that the "ibexpress" unit is included in
767 >     each project's source file (*.lpr).
768 >
769 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
770 >     exists, you have to first open the package in the IDE and then close it. This
771 >     adds it to the most recently accessed packages list. To make it permanently
772 >     available, add the package name to lazarus' staticpackages.inc file.
773 >
774 >         Thanks to Julio Jiménez for suggesting support of console mode.
775 >
776 > 7.   SQL Parser can now accept quoted strings that include new lines
777 >
778 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
779 >     of text on start of edit. This is particularly useful when tabbing to a
780 >     column and then inserting text.
781 >
782 > 9.   New Examples provided for IB Services and ISQLMonitor.
783 >
784 > 10. Fix error when writing to blob streams that recorded only the last buffer
785 >    write in the blob stream. In most cases, this did not cause a problem as the
786 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
787 >    of a graphic type prefix was lost which caused a problem when the image could
788 >        not be automatically recognised.
789 >
790 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
791 >    already open" errors due to random numbers used for the cursor name being identical.
792 >
793 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
794 >    when opening the table and the Primary Key is the last or only column in the
795 >    table. Thanks to Rick Hoover for the fix.
796 >
797 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
798 >    of "UTF-8", and update list of available database character sets. Existing
799 >    users should check the current lc_ctype setting in their applications.

809 >
810 > 3.  "Employees" example performance improvements when scrolling.
811 >
812 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
813 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
814 >    random image cached).
815 >
816 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
817 >
818 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
819 >    even when further rows exist.
820 >
821 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
822 >    always be derived from panel height and setting this property can cause confusion.
823 >    Note for existing projects: to avoid a missing property error at run time,
824 >    each form using the DBControlGrid must be opened, updated and saved in the IDE

839 >    and "AfterExecQuery". The first three are called after the same event is called
840 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
841 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
842 >    enable monitoring of transaction status changes for a given transaction to be
843 >    handled in a single place. For example, when a change to the dataset occurs
844 >    an indicator can be set that shows the user that in order to save changes,
845 >    the transaction should be committed.  Rather than doing this per dataset, this
846 >    can now be done per transaction.
847 >
848 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
849 >    the dataset is scrolled. However, any changes to the current row are, by default,
850 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
851 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
852 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
853 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
854 >    then IBX will attempt to post any unsaved changes before the dataset is closed
855 >    (and after the BeforeClose event handler is called). The exception is when the
856 >    dataset is being closed as a result of a transaction rollback. In this case,
857 >    no action is taken and any unsaved  changes are discarded. This avoids both
858 >    unnecessary overhead and the risk that a validation error may occur in the Post
859 >    raising an exception and thereby preventing a rollback.
860 >
861 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
862 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
863 >    width. Display Widths are now corrected by dividing by the max byte width per character.
864 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
865 >    the byte width divided by 4. The byte width of each character set is determined
866 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
867 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
868 >
869 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
870 >
871 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
872 >    control loses focus. Default Key press default interval reduced to 200ms.
873 >
874 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
875 >    when dataset rows are less than visible rows.
876 >
877 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
878 >    does not exist or DataSet is empty. More responsive on dataset open. New event
879 >    OnRestorePosition. Column sort disabled if no header row.
880 >
881 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
882 >    while dataset state is dsInsert. Avoids posting errors.
883 >
884 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
885 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
886 >
887 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
888 >
889 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
890 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
891 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
892 >    always "posts" the current record regardless or whether or not it may be more appropriate
893 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
894 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
895 >    as the first action of the "Post" method and allows the handler to convert the Post
896 >    into a Cancel if that is the appropriate action on moving to a different row. This is
897 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
898 >    raised here, but it may still be more appropriate to validate a post and signal
899 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
900 >
901 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
902 >    separated list. Each library name on the list is tried in turn, in left to right
903 >    order with the first found being used as the firebird library. By default, on Linux,
904 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
905 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
906 >
907 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
908 >    then it will still attempt to access the database via the Firebird Server and will
909 >    require a username and password. If only the pathname is given, then the username
910 >    and password should be omitted and the unix file permissions are used to grant
911 >    access.

914 >
915 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
916 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
917 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
918 >    corresponds to a row of the linked DataSource. Any data aware control on the
919 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
920 >
921 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
922 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
923 >   takes place during database access. This may be useful when there are performance issues with
924 >   the change of cursor. Setting the property to false suppresses the change of cursor.
925 >
926 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
927 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
928 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
929 >   making all changes permanent immediately rather than when the transaction is explicitly
930 >   committed.
931 >
932 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
933 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

941   1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
942     This is typically used during an "OnBeforeOpen" event handler to manipulate the
# Line 16 | Line 954 | IBX Change Log  version
954     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
955     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
956     to revise the available list and restrict it to items that are prefixed by the
957 <   typed text (either case sensitive or case insenstive). Autoinsert allows a
957 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
958     newly typed entry to be added to the list dataset and included in the available
959     list items.
