2 >
3 > 1. IBUtils.FormatTimeZoneOffset A zero offset now includes a preceding '+' sign.
4 >
5 > 2. TFBStatement.DoJournaling now exits immediately if journaling is not active. The
6 >   motivation for this is to avoid calling the Firebird API function 'getInfo'
7 >   unnecesarily. This function can return an error if an incompatible parameter type was
8 >   applied to the statement and hence can confuse resolving the bug. Note: a
9 >   specific case is in (e.g.) OpenCursorAtStart method when the array of const includes a
10 >   TDateTime. In this case, the param is set to a floating point type rather than
11 >   a Firebird datetime (array of const loses the distinction).
12 >
13 > 3. TFBAttachment.SetParameters. if an attempt is made to set a parameter with a float
14 >   value, the metadata type is checked to see if the parameter is a Date/Time type. If so then
15 >   the value is assumed to be a TDateTime and the parameter is set using the AsDateTime
16 >   property. Otherwise, the value is assumed to be a floating point type and the AsDouble
17 >   property is used to set the property. This avoids the specific example given above.
18 >
19 > 4. IBHeader (legacy interface only) Definition of Start_Transaction changed to use
20 >   varargs - win64 compatibility issue.
21 >
22 > 5. FB25Blob: last parameter of call to isc_blob_lookup_desc is now set to nil. This
23 >   avoids memory corruption with Firebird 4 when using the legacy interface.

26 >
27 > 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
28 >   checks for range checking.
29 >
30 > 2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
31 >   any additional error information is decoded.
32 >
33 > 3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
34 >   charsetid is now preserved and size is set to default blob size. Now aligns with
35 >   FB3 and later.
36 >
37 > 4. DDL and DML string literals are now explicitly set to the connection character
38 >   set rather than the default character set provided by the compiler.
39 >
40 > 5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
41 >   now makes use of the RTL fpwidestring unit for support of international character
42 >   sets.
43 >
44 > 6. Database exception handling (see section 9.3 in user guide).
45 >    * For FB3 and later API: Connection Character set now applied to message returned
46 >      by fb_interpret and message then transliterated if necessary to the system character set.
47 >    * For Legacy API: The message character set is guessed as UTF8 unless invalid
48 >      UTF8 characters found when connection character set is assumed. Message then
49 >      transliterated if necessary to system character set.
50 >      Note: this difference of behaviour is because legacy API presents exception messages
51 >      "as is", while FB3 server attempts to transliterate to connection character set.
52 >
53 > FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
54 >
55 > 1. Support package fbudr added for support of User Defined Routines (UDRs), and package
56 >   fbudrtestbed for client side debugging of UDR libraries.
57 >
58 > 2. Package layout changed with introduction of udr support. IB*.pas files moved from
59 >    root directory to "client". IBHeader moved to "Client".
60 >
61 > 3. Delphi packages: all packages now compile .dcp and .bpi files to either
62 >   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
63 >   fbintf.dcp and fbintf.bpi files from other locations.
64 >
65 > 4. Client side journaling support added. Interface changes
66 >   IAttachment
67 >    function JournalingActive: boolean;
68 >    function GetJournalOptions: TJournalOptions;
69 >    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
70 >    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
71 >    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
72 >    procedure StopJournaling(RetainJournal: boolean);
73 >
74 > 5. Transactions may now be given a local transaction name:
75 >   IFirebirdAPI
76 >     function StartTransaction(Attachments: array of IAttachment;
77 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
78 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
79 >             aName: AnsiString=''): ITransaction; overload;
80 >     function StartTransaction(Attachments: array of IAttachment;
81 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
82 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
83 >             aName: AnsiString=''): ITransaction; overload;
84 >
85 >   IAttachment
86 >    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
87 >    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
88 >    function StartTransaction(TPB: array of byte;
89 >                              DefaultCompletion: TTransactionCompletion=taCommit;
90 >                              aName: AnsiString=''): ITransaction; overload;
91 >    function StartTransaction(TPB: ITPB;
92 >                              DefaultCompletion: TTransactionCompletion=taCommit;
93 >                              aName: AnsiString=''): ITransaction; overload;
94 >
95 >  ITransaction
96 >    function GetTransactionName: AnsiString;
97 >    procedure SetTransactionName(aValue: AnsiString);
98 >
99 > 6. Additional Transaction information
100 >     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
101 >
102 >   ITransaction
103 >     function GetDefaultCompletion: TTransactionCompletion;
104 >     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
105 >
106 > 7. New IAttachment helper functions
107 >     function HasTable(aTableName: AnsiString): boolean;
108 >     function HasFunction(aFunctionName: AnsiString): boolean;
109 >     function HasProcedure(aProcName: AnsiString): boolean;
110 >     function GetAttachmentID: integer;
111 >     function GetCharSetID: integer;
112 >
113 > 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
114 >   will be allocated for batch operations.
115 >
116 > 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
117 >    function GetStatement: IStatement;
118 >    function GetTransaction: ITransaction;
119 >    function GetAttachment: IAttachment;
120 >
121 > 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
122 >    interfaces.
123 >
124 > 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
125 >    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
126 >    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
127 >    of numerics without loss of precision.
128 >
129 > 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
130 >
131 > 13. ISQLParams new method "Clear"
132 >
133 > 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
134 >    request rather than on attachment connect.
135 >
136 > 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
137 >    fact that SQLCodes are soon to be deprecated. In the future, the other options
138 >    will be silently ignored if SQLCode support is not present in the Firebird
139 >    Client library.
140 >
141 > 16. ITransaction changes Rollback and Commit from procedures to functions:
142 >      function Commit(Force: boolean=false): TTrCompletionState;
143 >      function Rollback(Force: boolean=false): TTrCompletionState;
144 >
145 >    Specifically, this is to allow the functions to report back a failed commit or
146 >    rollback when Force = true. In the case, the transaction handle has been
147 >    released, while the transaction remains in limbo.
148 >
149 > 17. IAttachment ExecImmediate.
150 >    When the transaction parameters are provided as an array of const and the
151 >    statement fails, the transaction is rolledback (forced) before the exception
152 >    is raised.
153 >
154 > 18. In Firebird 3 and later API: the status vector is now a thread var, as was
155 >    already the case with the legacy API. Avoids problems when calling underlying
156 >    Firebird API in multiple threads.
157 >
158 > 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
159 >    reasons.
160 >
161 > 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
162 >
163 > 21. TSQLXMLReader: handle 'blob' as a reserved word
164 >
165 > 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
166 >
167 >
168 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
169 >
170 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
171 >
172 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
173 >   using remote protocol. Scrollable cursors with remote database expected to
174 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
175 >   a not supported error.
176 >
177 > 3. IStatement: new function;
178 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
179 >    TStatementFlags = set of TStatementFlag;
180 >    function GetFlags: TStatementFlags;
181 >
182 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
183 >   compatibility.
184 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
185 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
186 >   to be used with Update...Retruning statements that return a singleton row,
187 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
188 >   it will open the cursor and return the first row only.
189 >
190 > 5. ITransaction: new functions:
191 >    function GetIsReadOnly: boolean;
192 >    function GetTransactionID: integer;
193 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
194 >    function GetTrInformation(Request: byte): ITrInformation; overload;
195 >
196 >   The latter two return the Transaction Information block. The first two extract
197 >   information the Transaction Information block
198 >
199 > 6. New function TSQLTokeniser.ReadCharacters
200 >   Used internally.
201 >
202 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
203 >   parameter placeholders instead of named parameters.
204 >
205 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
206 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
207 >
208 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
209 >   used to get an IBError Message instead of isc_interprete.
210 >
211 > 10. Internal tidyup. Native code now used for decoding integers and the events
212 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
213 >    isc_event_block and isc_event_counts.
214 >
215 > 11. New IAttachment function
216 >     function GetAttachmentID: integer;
217 >
218 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
219 >    subclasses to enable UDR support.
220 >
221 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
222 >
223 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
224 >
225 > 2. IStatement: new methods:
226 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
227 >    function GetStaleReferenceChecks: boolean;
228 >
229 >   In previous versions, stale reference checks were always enabled. This allows the
230 >   user to disable them on a per statement basis. Note this can risk out-of-date
231 >   statement BLR. See User Guide.
232 >
233 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
234 >   stored procedure and hence avoids replacing named parameters within a containing
235 >   BEGIN..END block.
236 >
237 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
238 >   zero is now treated as a special case to avoid the risk of floating point
239 >   rounding errors affecting pure integers.
240 >
241 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
242 >
243 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
244 >   SQL Parameter metadata (methods moved from ISQLParam).
245 >
246 > 7. ISQLParam: new method
247 >     function getColMetadata: IParamMetaData;
248 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
249 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
250 >   setting a VARCHAR column to an integer value.
251 >
252 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
253 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
254 >   also IAttachment:
255 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
256 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
257 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
258 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
259 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
260 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
261 >                       GenerateParamNames: boolean=false;
262 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
263 >
264 > 9. Support for scrollable cursors added. New/updated methods:
265 >   IAttachment:
266 >    function HasScollableCursors: boolean;
267 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
268 >                             Scrollable: boolean=false): IResultSet; overload;
269 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
270 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
271 >                             params: array of const): IResultSet; overload;
272 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
273 >                             params: array of const): IResultSet; overload;
274 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
275 >                             params: array of const): IResultSet; overload;
276 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
277 >                             Scrollable: boolean=false): IResultSet; overload;
278 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
279 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
280 >                             params: array of const): IResultSet; overload;
281 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
282 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
283 >                             params: array of const): IResultSet; overload;
284 >   IStatement:
285 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
286 >   IResultSet:
287 >    function FetchPrior: boolean; {fetch previous record}
288 >    function FetchFirst:boolean; {fetch first record}
289 >    function FetchLast: boolean; {fetch last record}
290 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
291 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
292 >    function IsBof: boolean;
293 >
294 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
295 >
296 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
297 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
298 >    output by the tokeniser will now use the platform specific lineEnding regardless
299 >    of whether the input uses the CRLF or LF as a line separator.
300 >
301 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
302 >
303 >
304 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
305 >
306 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
307 >
308 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
309 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
310 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
311 >   separate server interaction. This is intended as a performance optimisation.
312 >
313 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
314 >   IAttachment interface functions:
315 >
316 >    function GetInlineBlobLimit: integer;
317 >    procedure SetInlineBlobLimit(limit: integer);
318 >
319 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
320 >   user as the functionality is embedded in the implementation of the IStatement
321 >   interface. Three new functions are defined:
322 >
323 >    procedure AddToBatch;
324 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
325 >    procedure CancelBatch;
326 >    function GetBatchCompletion: IBatchCompletion;
327 >    function GetBatchRowLimit: integer;
328 >    procedure SetBatchRowLimit(aLimit: integer);
329 >
330 >   Also
331 >
332 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
333 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
334 >
335 >   For more information see the User Guide.
336 >
337 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
338 >   provided with the EIBInterBaseError now include all three parts.
339 >
340 > 5. Firebird.pas and include files updated to Firebird 4.0.0
341 >
342 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
343 >   Returns SQL Statement type as a text string;
344 >
345 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
346 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
347 >
348 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
349 >
350 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
351 >   typo in FB30Statement.pas that caused an unknown parameter error.
352 >
353 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
354 >
355 > 1. Imported (Firebird) constants updated for Firebird 4.
356 >
357 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
358 >
359 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
360 >
361 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
362 >
363 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
364 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
365 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
366 >   type safe access to the Firebird IMaster interface and avoids the need to turn
367 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
368 >
369 > 6. New IFirebirdAPI Calls:
370 >    function HasLocalTZDB: boolean;
371 >    function HasTimeZoneSupport: boolean;
372 >    function HasExtendedTZSupport: boolean;
373 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
374 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
375 >
376 > 7. New IAttachment Calls:
377 >    function HasDecFloatSupport: boolean;
378 >    function GetTimeZoneServices: ITimeZoneServices;
379 >    function HasTimeZoneSupport: boolean;
380 >
381 > 8. New Interface ITimeZoneServices.
382 >
383 > 9. New ISQLData API Calls:
384 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
385 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
386 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
387 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
388 >    function GetAsUTCDateTime: TDateTime;
389 >    function GetAsBCD: tBCD;
390 >
391 > 10. New ISQLParam API Calls
392 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;

587   1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
588  
# Line 7 | Line 591 | FBINTF Change Log  version
591       function GetDefaultCharSetID: integer;
592  
593     These return, respectively, true if a connection default character set was
594 <   specified and the character set id of the connection defautl character set.
594 >   specified and the character set id of the connection default character set.
595 >   The DefaultCharSetID is cached when the connection is opened and hence does not
596 >   require a database lookup.
597  
598   3. Avoid exception when a text blob is a stored procedure parameter.
599  
600   4. Update test suite to include a test for a stored proc returning a text blob.
601  
602 + 5. IAttachment: add
603 +      function GetRemoteProtocol: AnsiString;
604 +      function GetODSMajorVersion: integer;
605 +      function GetODSMinorVersion: integer;
606 +      function GetAuthenticationMethod: AnsiString;
607 +
608 +   These results are cached when the connection is opened and hence do not
609 +   require a database lookup.
610 +
611 + 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
612 +   connect string used to create/connect to the database.
613 +
614 + 7. IAttachment: Create Database using SQL statement. The username and password
615 +   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
616 +   It is now possible to use IAttachment disconnect/connect to reconnect to
617 +   a database for which the initial connection was established by a create
618 +   database sql statement. Available in FPC only.
619 +
620 + 8. Update Test 1 to test 5, 6 and 7 above.
621 +
622 + 9. IBUtils code tidy up.
623 +
624 + 10. Parameter Block interfaces "find" method. As documented, this should have
625 +   returned a nil interface when the item could not be found. Instead, an empty
626 +   interface item was returned. "Find" now works as documented and will return
627 +   a nil interface if the item cannot be found.
628 +
629 + 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
630 +
631 + 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
632 +    requests with additional parameters. This is to enable support for fb_info_page_contents
633 +    (return of page contents). Response to fb_info_page_contents returned as
634 +    a string with code page CP_NONE.
635 +
636 + 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
637 +    test suite updated.
638 +
639 + 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
640 +    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
641 +
642 + 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
643 +    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
644 +    default connection port to be specified.
