10 >
11 >
12 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
13 >   and is used to override the default settings in the client side "firebird.conf" This
14 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
15 >   Each line of the string list should be a setting in the same format as "firebird.conf".
16 >   For example "WireCompression = true" in order to request wire compression on the client side.
17 >
18 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
19 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
20 >   also require a compatible setting in the server side "firebird.conf". For example
21 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
22 >   compression to be used.
23 >
24 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
25 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
26 >   ibx/examples/dbinfo for examples of how to display this information.
27 >
28 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
29 >   is a "convenience" property. If set the "WireCompression=true" is added to the
30 >   ConfigOverrides. If unchecked then this setting is removed.
31 >
32 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
33 >   not "INT64".
34 >
35 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
36 >   These are:
37 >    property TimestampFormat: string;
38 >    property DateFormat: string;
39 >    property TimeFormat: string;
40 >
41 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
42 >   DATETIME and TIME. The format strings use the standard FPC date/time format
43 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
44 >
45 >   If any of the above properties are set to an empty string, then the locale default
46 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
47 >   locale default is extended by appending '.zzz' to include milliseconds.
48 >
49 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
50 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
51 >
52 > 5. New published property for TIBCSVDataOut:
53 >     property QuoteStrings: boolean (default true)
54 >
55 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
56 >   used to delimit each and every string in the output.
57 >
58 > 6. New published properties for TIBCSVDataOut:
59 >    property FieldSeparator: string;
60 >    property HeaderSeparator: string;
61 >
62 >   Respectively, these provide the separator character(s) used to separate fields
63 >   in data and header rows. Both default to ','.
64 >
65 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
66 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
67 >    property OnFormatTextString;
68 >
69 >   This event handler can be used to process text strings before they are included
70 >   in the output e.g. to replace unprintable characters with alternative strings.
71 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
72 >
73 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
74 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
75 >   and without raising and exception if it does not.
76 >
77 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
78 >   consistency with SQL queries.
79 >
80 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
81 >    When true, SQL statement parameter names are parsed case sensitive. Note for
82 >    TIBDataSet only applies to Select query.
83 >
84 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
85 >    an IDE exception.
86 >
87 > 12. LocalDBSupport: initial database creation should now work correctly
88 >    when the schema source is an sql file.
89 >
90 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
91 >    when defined, this handler will be called by the internal TIBXScript during
92 >    initial database creation when the schema source is an sql file and may be used
93 >    to provide a visual indication of progress in console mode.
94 >
95 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
96 >    to true while a new local database is being created and its schema populated.
97 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
98 >    when the database is disconnected/connected during the create DB procedure.
99 >
100 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
101 >    are now always ignored and replaced by the user name and password provided as
102 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
103 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
104 >    completely ignored if this property is true.
105 >
106 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
107 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
108 >    ImageIndex and SelectImageIndex values on AddNode.
109 >
110 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
111 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
112 >    the same database connection.
113 >
114 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
115 >    if provided, this should be an conditional SQL expression suitable for
116 >    including in an SQL Select statement "where" clause. If non-empty and the
117 >    "Filtered" property is true then the SQL expression provided as the value of
118 >    the "Filter" property is "ANDed" with any existing condition statement
119 >    in the SQL statement's "Where" clause.
120 >
121 >    If the "Filter" property is set at run time, the "Filtered" property is true
122 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
123 >
124 >    The "Filter" condition may include IBX style parameters. In which case, their
125 >    value must be set by the dataset's "OnBeforeOpen" event handler.
126 >
127 >    This is a public property for TIBDataSet and TIBQuery query and intended for
128 >    use at run time.
129 >
130 >    Note: The property is a published property of TIBTable. The TIBTable functionality
131 >    is unaffected by this change.
132 >
133 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
134 >
135 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
136 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
137 >   mode apps.
138 >
139 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
140 >   statement. This avoids problems if "Execute Block" is used as the Query.
141 >
142 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
143 >   internal SQL tokeniser routines.
144 >
145 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
146 >   as a select statement, with or without CTEs.
147 >
148 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
149 >
150 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
151 >   internal SQL tokeniser routines.
152 >
153 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
154 >    being raised for valid set statements processed by a data formatter.
155 >
156 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
157 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
158 >   the path of the Firebird Library used by the database/services connection.
159 >
160 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
161 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
162 >   services connection.
163 >
164 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
165 >   or param name is not a valid SQL identifier.
166 >
167 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
168 >    view of whether the text box should be editable when no DataSource is specified.
169 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
170 >    ReadOnly is false, the text box is editable when no DataSource is specified.
171 >
172 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
173 >    the FBLIB environment variable. If you do not want to permit this then you
174 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
175 >    this setting.
176 >
177 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
178 >
179 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
180 >   Utf8EscapeControlChars
181 >
182 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
183 >
184 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
185 > all previous copies of the IBX source code tree before installing this release.
186 >
187 > The IBX packages used by most users have not changed, with one exception. The
188 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
189 > to use the IBServices unit in your applications, please add the iblegacyServices
190 > to the list of dependencies. To do this, open the Project Inspector and select
191 > Add->New Requirement and select "ibLegacyServices" from the list of available
192 > packages.
193 >
194 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
195 >   the IBServices unit providing what is intended to be a clearer and easier to
196 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
197 >   more information and the guide to "Firebird Service Management Using IBX".
198 >   As indicated above, the legacy services components are still available and
199 >   provided in a separate package. There is no need to update working applications
200 >   using the older versions except for an additional package dependency.
201 >
202 > 2. The IBX packages and source code tree have been re-organised in an attempt to
203 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
204 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
205 >   new set of IBX packages.
206 >
207 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
208 >   updated to use the new Services API components.
209 >
210 > 4. The iblocal package has been updated to use the new Services API components.
211 >
212 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
213 >   TIBXSecurityService. It had been wrongly classified in the previous version
214 >   as a per database configuration item. It is global to a server and hence
215 >   correctly positioned as part of the Security Package. In the DBAdmin example,
216 >   the setting has moved to the mappings page.
217 >
218 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
219 >   are ignored.
220 >
221 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
222 >   closed before the database is dropped. Before and After Disconnect event handlers
223 >   are also fired.
224 >
225 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
226 >   is started and not just the first time.
227 >
228 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
229 >   depenendency with comp type.
230 >
231 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
232 >
233 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
234 >    then this is recognised and not ignored.
235 >
236 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
237 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
238 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
239 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
240 >
241 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
242 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
243 >    counters for the select query. Note: stats accumulate after each fetch from
244 >    the database. To get total query cost after open, call the "Last" method
245 >    and then GetPerfStatistics.
246 >
247 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
248 >
249 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
250 >    in parenthesises.
251 >
252 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
253 >    SQL identifiers are always delimited by double quotes. If false, then they are
254 >    only delimited if the identifier is a reserved word, contains lower case or special
255 >    characters. Set this property to true to retain previous behaviour.
256 >
257 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
258 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
259 >
260 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
261 >       property MasterDetailDelay: integer {defaults to zero}
262 >
263 >    When non-zero and the dataset is a detail table referencing a master table
264 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
265 >    then a synchronisation delay is added (in milliseconds) between the master
266 >    row changing and the detail dataset being re-opened. If the master dataset
267 >    is scrolled before the delay expires then the delay is reset. This can be used
268 >    to avoid performance overheads when scrolling through a large master dataset.
269 >
270 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
271 >    chreads unit must be included in your project. TTimer is not used in order
272 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
273 >
274 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
275 >    with Extract Option eoDatabase.
276 >
277 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
278 >    When a deLayoutChanged event is reported on the ListSource dataset, the
279 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
280 >    relationship with the control's datasource (master).
281 >
282 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
283 >
284 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
285 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
286 >
287 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
288 >    DDL (Firebird 3 and later only).
289 >
290 > 22. TIBLookupComboBox Autocomplete Fixes:
291 >    i. Only appended text is now selected after autocomplete.
292 >    ii. Uppercase keys no longer ignored for autocomplete.
293 >    iii. Retain Prefix case is now honoured correctly.
294 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
295 >        before autocomplete performed. i.e. behaviour now the same as when
296 >        no DataSource assigned.
297 >
298 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
299 >    between SQL statements.
300 >
301 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
302 >    ObjectNames are converted to upper case before matching against metadata object
303 >    names, unless the objectname is delimited by double quotes, in which case, the
304 >    double quotes are removed and the remaining string is used (unmodified) to match
305 >    against the metadata object name.
306 >
307 >    If true then the ObjectName is used as is without modification and matched
308 >    against the metadata object name. No attempt is made to remove double quotes.
309 >
310 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
311 >    with eoTrigger, these extract types can be used to select only Database Triggers,
312 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
313 >
314 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
315 >    statement separate character is now reset to the default (';').
316 >
317 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
318 >
319 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
320 >    a commit or reconnect statement and instead activated only when next SQL statement
321 >    is executed.
322 >
323 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
324 >
325 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
326 >    converting statement to upper case.
327 >
328 > 31. TIBExtract: metadata comments now supported. New published property
329 >    IncludeMetaDataComments (default true). If true then metadata comments included
330 >    in extracted DDL. New Extract Object member eoComments. This may be used with
331 >    ExtractObject method to list all metadata comments.
332 >
333 > 32. TIBExtract: ListObjectNames method added.
334 >
335 > 33. Updated Database component editor to support additional connection string
336 >    types.
337 >
338 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
339 >
340 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
341 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
342 > RELEASE.
343 >
344 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
345 >
346 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
347 >
348 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
349 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
350 >   information). However, this is also a very useful mechanism for returning updated computed by
351 >   column values. Values returned as a result of executing an Insert or Update statement
352 >   replace existing values in the current row for each corresponding column.
353 >
354 >   Previously, if a dataset's select query included read only (computed by) fields then
355 >   an automatic row refresh was performed after an insert or update query had been processed,
356 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
357 >   that an automatic refresh is no longer performed if an insert or update query contains
358 >   a returning clause that updates one or more fields on the current row. A full row
359 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
360 >   field values and the select query contains read only fields. Use of Insert/update
361 >   returning should be significantly more efficient than executing a refresh query.
362 >
363 >   This behaviour change is intended to be backwards compatible and there should be no need to change
364 >   existing programs, other than to improve performance by using the new capability.
365 >
366 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
367 >   they are called when the dataset row is being deleted, there is no value in
368 >   updating the current record from the query result. Instead, a new event handler
369 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
370 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
371 >   by the query. The event handler can then interrogate the query results and
372 >   perform whatever action is necessary. For example to confirm, to the user,
373 >   the deletion of a row with the returned values.
374 >
375 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
376 >   any Computed By or Identity Columns. The IBTables example has been updated to
377 >   illustrate the computation of the employee Full Name on update.
378 >
379 > 5. TIBTable: The GeneratorField property is now published.
380 >
381 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
382 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
383 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
384 >   each Identity column after the insert is executed.
385 >
386 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
387 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
388 >   Insert..Returning clause.
389 >
390 > 8. TIBGenerator: small performance improvement by not preparing query each time
391 >   a new value is generated.
392 >
393 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
394 >
395 > 10. Property editors will now sync table name to a System Table when "Include System
396 >    Tables" is selected and the query is for a System Table.
397 >
398 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
399 >    values are no longer converted to milliseconds from TDateTime and then back again
400 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
401 >
402 > 12. Property Editors handling of Stored Procedures.
403 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
404 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
405 >      query).
406 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
407 >
408 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
409 >    can be used to select a package. If non-empty, the stored procedure name is
410 >    expected to be a stored procedure defined in the specified package and the
411 >    generated SQL will be as required for a stored procedure located in a package.
412 >
413 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
414 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
415 >    which a stored procedure can be selected. With no package name selected, non-package
416 >    stored procedures are listed.
417 >
418 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
419 >    for password on reconnect.
420 >
421 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
422 >    and character set name.
423 >
424 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
425 >    DB info lookups"
426 >
427 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
428 >
429 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
430 >
431 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
432 >    parameters. This stops an exception being raised when the field cannot be
433 >    located in the record buffer.
434 >
435 > 21. Property Editors now automatically include System Tables when opened and when the query table
436 >    is a System Table.
437 >
438 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
439 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
440 >
441 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
442 >    add the SPB item isc_spb_expected_db. This names a database using
443 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a

445 >
446 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.

448 >
449 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
450 >
451 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
452 >    databasenames. These are respectively expanded to the local system's temp directory
453 >    (including trailing delimiter) or to a prescribed data directory (including
454 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
455 >    in the user's home directory. The hidden directory name is either the string returned
456 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
457 >    Under Windows, the directory is the same as the Data Directory as decribed
458 >    above but instead prefixed by the User's application data path. These may be
459 >    used to improve application portability for Personal Databases.
460 >
461 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
462 >    this has not worked for a long time and is not useful either. FieldDefs should be
463 >    managed using the Fields Editor as with any other dataset. To access the fields
464 >    editor for a TIBTable component, double click on the component. The fields editor
465 >    is then displayed.
466 >
467 > 28. TIBDatabaseInfo: new properties/function
468 >     * DateDBCreated (returns date/time database created)
469 >     * TransactionCount (returns no. of active transactions)

480 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
481 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
482 >
483 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
484 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
485 >    firing during backup and restore.
486 >
487 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
488 >    for verbose output using the new property "StatisticsRequested".

499 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
500 >    option on a database.
501 >
502 > 37. TIBCustomService: Assign method implemented to allow copying of service login
503 >    context between service API components. "Detach" method now only detaches

533 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
534  
535   1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
536     changes.
# Line 9 | Line 541 | IBX Change Log  version
541   3. Changes consequential on moving fbintf character set utility functions from
542     IFirebirdAPI to IAttachment.
543  
544 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
545 +
546 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
547 +   results in autocomplete ignoring prefix text.
548 +
549 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
550 +   entering a new name into the text box.
551 +
552 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
553 +   Firebird rather than recomputing it.
554 +
555 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
556 +   screen centre. Previously some were "poDesigned" which may be inappropriate
557 +   for multi monitor desktops.
558 +
559 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
560 +
561 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
562 +    a transaction and always reset the object.
563 +
564 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
565 +
566 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
567 +
568 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
569 +    to a gbak format archive.
570 +
571 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
572 +
573 + 16. IBLocaldb: Drop database if error creating an empty database.
574 +
575 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
576 +    unless selected node not in current dataset.
577 +
578 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
579 +    to TIBCustomService, and IBlocalDB code tidy up.
580 +
581 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
582 +    behaviour due to uninitialised variable.
583 +
584 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
585 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
586 +
587 + 21. IBSQL: When Database changed ensure that all resources are freed.
588 +
589 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
590 +
591 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
592 +    * Line Wrap on SQL Token boundaries (on user command)
593 +    * auto-complete table names in drop down list of table names
594 +    * Double click on tablename or field name adds to SQL text
595 +
596 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
597 +
598 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
599 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
600 +    workaround for a problem in fpc 3.0.4 win64).
601 +
602 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
603 +
604 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
605 +
606   IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
607  
608   1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
# Line 29 | Line 623 | IBX Change Log  version
623     that BindFields is called when the query is next activated. Avoids FieldName
624     not found error.
625  
626 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
627 +   purpose and allows the programmer to define any action they want for Update, Insert
628 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
629 +   filtering of updates, or use of statements such as Grant or Revoke instead of
630 +   normal DML. See User Manual for more information.
631 +
632   IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
633  
634   1. TIBEvents: Fix uninitialised variable that could result in lost events.
