1 tony 359 FBINTF Change Log version (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
2    
3     1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
4    
5     2. Remove constraint in IAttachment.HasScollableCursors that returned false when
6     using remote protocol. Scrollable cursors with remote database expected to
7     be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
8     a not supported error.
9    
10     3. IStatement: new function;
11     TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
12     TStatementFlags = set of TStatementFlag;
13     function GetFlags: TStatementFlags;
14    
15     4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
16     compatibility.
17     In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
18     type changes from ExecProcedure to Select. So that ExecuteQuery can continue
19     to be used with Update...Retruning statements that return a singleton row,
20     instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
21     it will open the cursor and return the first row only.
22    
23     5. ITransaction: new functions:
24     function GetIsReadOnly: boolean;
25     function GetTransactionID: integer;
26     function GetTrInformation(Requests: array of byte): ITrInformation; overload;
27     function GetTrInformation(Request: byte): ITrInformation; overload;
28    
29     The latter two return the Transaction Information block. The first two extract
30     information the Transaction Information block
31    
32     6. New function TSQLTokeniser.ReadCharacters
33     Used internally.
34    
35     7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
36     parameter placeholders instead of named parameters.
37    
38     8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
39     transaction handle is now ignored if Rollback/Commit is called with Force=true
40    
41 tony 356 FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
42 tony 347
43     1. TFBClientAPI.GetProcAddr. Add check for nil reference.
44    
45     2. IStatement: new methods:
46     procedure SetStaleReferenceChecks(Enable:boolean); {default true}
47     function GetStaleReferenceChecks: boolean;
48    
49     In previous versions, stale reference checks were always enabled. This allows the
50     user to disable them on a per statement basis. Note this can risk out-of-date
51     statement BLR. See User Guide.
52    
53 tony 348 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
54     stored procedure and hence avoids replacing named parameters within a containing
55     BEGIN..END block.
56    
57 tony 349 4. ISQLParam: using a string value to set an integer field with a scale factor of
58     zero is now treated as a special case to avoid the risk of floating point
59     rounding errors affecting pure integers.
60    
61     5. ISQLParam: Review and tidy-up of SetAsString for numeric types.
62    
63     6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
64     SQL Parameter metadata (methods moved from ISQLParam).
65    
66     7. ISQLParam: new method
67     function getColMetadata: IParamMetaData;
68     This instance of IParamMetaData returns the original column metadata which is unmutable.
69     Note: ISQLParam metadata can change after a parameter value has been set e.g when
70     setting a VARCHAR column to an integer value.
71    
72 tony 350 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
73     procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
74     also IAttachment:
75     function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
76     function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
77     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
78     aSQLDialect: integer; GenerateParamNames: boolean=false;
79     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
80     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
81     GenerateParamNames: boolean=false;
82     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
83 tony 349
84 tony 350 9. Support for scrollable cursors added. New/updated methods:
85     IAttachment:
86 tony 352 function HasScollableCursors: boolean;
87 tony 350 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
88     Scrollable: boolean=false): IResultSet; overload;
89     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
90     function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
91     params: array of const): IResultSet; overload;
92     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
93     params: array of const): IResultSet; overload;
94     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
95     params: array of const): IResultSet; overload;
96     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
97     Scrollable: boolean=false): IResultSet; overload;
98     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
99     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
100     params: array of const): IResultSet; overload;
101     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
102     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
103     params: array of const): IResultSet; overload;
104     IStatement:
105     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
106     IResultSet:
107     function FetchPrior: boolean; {fetch previous record}
108     function FetchFirst:boolean; {fetch first record}
109     function FetchLast: boolean; {fetch last record}
110     function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
111     function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
112     function IsBof: boolean;
113    
114 tony 353 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
115 tony 350
116 tony 353 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
117     may be noticeable when a line separator occurs inside quoted text. The quoted text
118     output by the tokeniser will now use the platform specific lineEnding regardless
119     of whether the input uses the CRLF or LF as a line separator.
120 tony 350
121 tony 353 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
122    
123    
124 tony 345 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
125    
126     1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
127    
128     2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
129     will now be encoded inline (i.e. as part of the parameter buffer) if they are
130     shorter than a pre-set limit. Longer values continue to be saved as blobs as a
131     separate server interaction. This is intended as a performance optimisation.
132    
133     The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
134     IAttachment interface functions:
135    
136     function GetInlineBlobLimit: integer;
137     procedure SetInlineBlobLimit(limit: integer);
138    
139     3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
140     user as the functionality is embedded in the implementation of the IStatement
141     interface. Three new functions are defined:
142    
143     procedure AddToBatch;
144     function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
145     procedure CancelBatch;
146     function GetBatchCompletion: IBatchCompletion;
147     function GetBatchRowLimit: integer;
148     procedure SetBatchRowLimit(aLimit: integer);
149    
150     Also
151    
152     function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
153     function HasBatchMode: boolean; {true if and only if IBatch Supported}
154    
155     For more information see the User Guide.
156    
157     4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
158     provided with the EIBInterBaseError now include all three parts.
159    
160     5. Firebird.pas and include files updated to Firebird 4.0.0
161    
162     6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
163     Returns SQL Statement type as a text string;
164    
165     7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
166     an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
167    
168 tony 340 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
169 tony 338
170     1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
171     typo in FB30Statement.pas that caused an unknown parameter error.
172    
173 tony 319 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
174 tony 308
175 tony 315 1. Imported (Firebird) constants updated for Firebird 4.
176    
177     2. Firebird.pas from Firebird 4 integrated into source code tree.
178    
179     3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
180    
181     4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
182    
183     5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
184     QueryInterface may be used to coerce this interface from IFirebirdAPI. The
185     interface provides a single method "function GetIMasterIntf: IMaster". This provides
186     type safe access to the Firebird IMaster interface and avoids the need to turn
187     off object checks when coercing "function GetIMaster: TObject" to IMaster.
188    
189     6. New IFirebirdAPI Calls:
190     function HasLocalTZDB: boolean;
191     function HasTimeZoneSupport: boolean;
192     function HasExtendedTZSupport: boolean;
193     procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
194     function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
195    
196     7. New IAttachment Calls:
197     function HasDecFloatSupport: boolean;
198     function GetTimeZoneServices: ITimeZoneServices;
199     function HasTimeZoneSupport: boolean;
200    
201     8. New Interface ITimeZoneServices.
202    
203     9. New ISQLData API Calls:
204     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
205     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
206     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
207     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
208     function GetAsUTCDateTime: TDateTime;
209     function GetAsBCD: tBCD;
210    
211     10. New ISQLParam API Calls
212     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
213     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
214     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
215     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
216     function GetAsUTCDateTime: TDateTime;
217     function GetAsBCD: tBCD;
218     function GetStatement: IStatement;
219     function GetTransaction: ITransaction;
220     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
221     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
222     procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
223     procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
224     procedure SetAsUTCDateTime(aUTCTime: TDateTime);
225     procedure SetAsBcd(aValue: tBCD);
226    
227     11. New IArray API Calls
228     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
229     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
230     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
231     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
232     function GetAsUTCDateTime(index: array of integer): TDateTime;
233     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
234     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
235     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
236     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
237    
238     12. Utility functions in IBUtils
239     function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
240     var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
241     procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
242     function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
243     function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
244     function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
245     function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
246    
247     13. IDPB, ITPB and ISPB: new interface method
248     function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
249     This is used to add a parameter block item by the string equivalent of its
250     symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
251    
252     14. IDPBItem/ITPBItem/ISPBItem: new interface method:
253     function getParamTypeName: AnsiString;
254    
255     15. fb_shutdown now called before unloading Firebird library. This can avoid a
256     SIGEVENT error when a programme using the embeded server is unloaded.
257    
258     FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
259    
260 tony 308 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
261     with a Firebrid 3 client library.
262    
263     2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
264     If a client library path is not explicitly provided and the FIREBIRD environment
265     variable is set then the directory given by this variable and any 'lib' subdirectory
266     are searched for the Firebird client library. Only if none is found, is the default
267     client library used.
268    
269     3. IUtil.FormatStatus now used to format error messages when using new API
270    
271     4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
272    
273     5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
274     returned using GetAsString and the string codepage is UTF8, the string is truncated so
275     that the byte length corresponds to the number of characters specified for the column.
276     SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
277     correct behaviour but may affect some implementations that relied upon automatic
278     trimming of trailing white space.
279    
280     6. New IFirebirdAPI Calls:
281     function GetClientMajor: integer;
282     function GetClientMinor: integer;
283    
284 tony 309 7. IColumnMetaData and IArrayMetaData: new method
285     function GetCharSetWidth: integer;
286 tony 308
287 tony 315 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
288 tony 309
289 tony 287 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
290     case sensitive
291    
292     2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
293    
294 tony 291 3. New API Calls:
295     IColumnMetaData.GetStatement
296     IColumnMetaData.GetTransaction
297 tony 315 ISQLData.GetStrDataLength
298 tony 291 IResults.GetStatement
299     IAttachment.OpenBlob (using Blob metadata)
300     IAttachment.OpenArray (using array metadata)
301    
302     4. FBMessages: removal of unused messages
303    
304     5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
305    
306     6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
307    
308 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
309 tony 265
310     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
311     where the second character of the parameter name is a numeric.
312    
313 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
314     This returns the isc_version connection information as one or more lines.
315     This is the same information as returned by isql with the -z option.
316 tony 265
317 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
318     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
319     compiler option then the Firebird 3 API is no longer compiled in.
320 tony 266
321 tony 270 4. IColumnMetaData: new method.
322    
323     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
324     dfDateTime, {SQL DATETIME}
325     dfTime);
326    
327     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
328    
329     This returns the max. number of characters returned by the "AsString" method
330     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
331    
332     5. Additional argument for IAttachment.PrepareWithNamedParameters -
333     CaseSensitiveParams: boolean = false
334    
335     If this argument is set to true then SQL parameter names are assumed to be case
336     sensitive and must be referenced (using ISQLParams.ByName) using the case
337     sensitive name.
338    
339     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
340     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
341     .AsCurrency) and then subsequently to update the value to a non-numeric string
342     using .AsString.
343    
344    
345    
346 tony 263 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
347 tony 238
348     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
349    
350 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
351     https://bugs.freepascal.org/view.php?id=30535
352    
353     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
354     named parameters and is intended to avoid problems with (e.g.) Execute Block
355     and processing internal parameters as statement parameters.
356    
357     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
358     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
359    
360     5. New function added to IB.pas
361    
362     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
363    
364     This allows a Firebird Library to be loaded from an explicit path. use the
365     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
366     the library. It is possible to load Firebird libraries from different locations
367     simultaneously, each with a distinct IFirebirdAPI.
368    
369 tony 233 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
370 tony 59
371 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
372     program compiled with -CR command line switch.
373    
374     2. IServiceManager additions (informational):
375     function getProtocol: TProtocol;
376     function getPortNo: AnsiString;
377    
378     3. IServiceManager improved error handling. Interfaces changed:
379     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
380     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
381     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
382    
383     4. IAttachment addition (informational)
384     function GetSecurityDatabase: AnsiString;
385    
386     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
387     thus now returns accumulated stats for a select statement from opening a cursor
388     up to the last fetch.
389    
390     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
391     the problem.
392    
393     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
394     replaces deprecated "comp" type.
395    
396 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
397 tony 209
398 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
399 tony 217
400 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
401    
402 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.

406    
407 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
408    
409 tony 109 2. IAttachment: add two new methods
410     function HasDefaultCharSet: boolean;
411     function GetDefaultCharSetID: integer;
412    
413     These return, respectively, true if a connection default character set was
414 tony 117 specified and the character set id of the connection default character set.
415     The DefaultCharSetID is cached when the connection is opened and hence does not
416     require a database lookup.
417 tony 109
418 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
419 tony 109
420 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
421    
422 tony 117 5. IAttachment: add
423     function GetRemoteProtocol: AnsiString;
424     function GetODSMajorVersion: integer;
425     function GetODSMinorVersion: integer;
426 tony 143 function GetAuthenticationMethod: AnsiString;
427 tony 117
428     These results are cached when the connection is opened and hence do not
429     require a database lookup.
430    
431     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
432     connect string used to create/connect to the database.
433    
434     7. IAttachment: Create Database using SQL statement. The username and password
435     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
436     It is now possible to use IAttachment disconnect/connect to reconnect to
437     a database for which the initial connection was established by a create
438 tony 120 database sql statement. Available in FPC only.
439 tony 117
440     8. Update Test 1 to test 5, 6 and 7 above.
441    
442     9. IBUtils code tidy up.
443    
444 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
445     returned a nil interface when the item could not be found. Instead, an empty
446     interface item was returned. "Find" now works as documented and will return
447     a nil interface if the item cannot be found.
448    
449     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
450    
451     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
452     requests with additional parameters. This is to enable support for fb_info_page_contents
453     (return of page contents). Response to fb_info_page_contents returned as
454     a string with code page CP_NONE.
455    
456     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
457     test suite updated.
458    
459     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
460     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
461    
462     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
463     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
464     default connection port to be specified.
465    
466 tony 107 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
467    
468 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
469     Scale is no longer ignored.
470    
471     2. Fix issues with setting SQL Param values using SetAsString with Date values
472     not in locale format but which are recognised by Firebird. Date values that
473     cannot be converted to a string using Pascal library are now passed through
474     to Firebird as Text Strings.
475    
476 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
477     UTF8 and not UNICODE_FSS.
478    
479     4. Charset ID problem. When using Firebird 3, with no default database character set
480     and a column has a non-default collation specified, an incorrect character set
481     id was being reported that could result in a 'division by zero' error when
482     used by IBX. This has now been fixed.
483    
484     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
485     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
486     the character sets supported can be updated on a per database basis. That is
487     it is possible to add a (Firebird) user defined character set to a database.
488    
489     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
490     set supported by Firebird with the API.
491    
492 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
493     in FBOutputBlock.pas and update test suite to include this item.
494 tony 60
495 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
496 tony 61
497 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
498     library or finding it by disk location, the PATH environment variable is now also set to
499     include the FIREBIRD directory. This is to ensure that the correct dlls in the
500     firebird client library dependencies are loaded.
501 tony 63
502 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
503    
504     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
505    
506     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
507    
508     13. FB30Statement: A check has been added to ensure that all SQL Parameters
509     have been given a value (including NULL). Previously, failing to set the
510     value of an SQL Parameter could give rise to unpredictable results or
511     an SQLDA error.
512    
513     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
514    
515 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
516     parameter in an array of const passed to IAttachment.OpenCursor, etc.
517 tony 68
518 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
519     of const passed to IAttachment.OpenCursor, etc.
520

523 tony 47
524 tony 56 1. Change syntax to Mode Delphi
525    
526     2. Change all uses of string type to explicit AnsiString in order to ensure
527     compatibility between Delphi and FPC.
528    
529     3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
530     defined for each interface.
531    
532     4. Generics syntax variations for Delphi added
533    
534     5. PChar replaced with PByte expect where an actual string is being referenced,
535     where PAnsiChar is used instead.
536    
537     6. Review of type definitions in IBExternals to ensure Delphi compatibility
538    
539     7. Testsuite updated for Delphi
540    
541     FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
542    
543 tony 47 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
544     large blobs and the FB3 API.
545    
546     2. Update Event Handling algorithm to avoid looping due to recreation of the
547     event block.
548    
549     3. Avoid invalid XSQLDA error when the only parameter is updated to null
550    
551     4. Array Handling: fix problem with text arrays with character set none. When the
552     DB connection has a default character set (e.g. UTF8), an error is raised by
553     Firebird if the space allocated is not enough to allow for transliteration, even
554     though it is not required for character set none.
555    
556     5. IBUtils: List of reserved words brought up-to-date
557    
558     6. Add ISQL style performance statistics collection to IStatement
559    
560     7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
561     CREATE DATABASE statement.
562    
563     8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
564     an array dimension is not mistaken for a named parameter prefix.
565    
566     9. Trim function no longer applied to result of GetAsString for SQL_TEXT
567     when Character set is octets. Avoids loss of non printable characters at start of string.
568    
569     10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
570     statistics for the last action. Requires use of procedure IStatement.EnableStatistics
571     to enable stats gathering.
572    
573     11. API Version information added as constants to IB.pas
574    
575     12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
576    
577     13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
