2 >
3 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4 >
5 > 2. IStatement: new methods:
6 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7 >    function GetStaleReferenceChecks: boolean;
8 >
9 >   In previous versions, stale reference checks were always enabled. This allows the
10 >   user to disable them on a per statement basis. Note this can risk out-of-date
11 >   statement BLR. See User Guide.
12 >
13 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14 >   stored procedure and hence avoids replacing named parameters within a containing
15 >   BEGIN..END block.
16 >
17 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 >   zero is now treated as a special case to avoid the risk of floating point
19 >   rounding errors affecting pure integers.
20 >
21 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22 >
23 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 >   SQL Parameter metadata (methods moved from ISQLParam).
25 >
26 > 7. ISQLParam: new method
27 >     function getColMetadata: IParamMetaData;
28 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
29 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 >   setting a VARCHAR column to an integer value.
31 >
32 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34 >   also IAttachment:
35 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
39 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41 >                       GenerateParamNames: boolean=false;
42 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43 >
44 > 9. Support for scrollable cursors added. New/updated methods:
45 >   IAttachment:
46 >    function HasScollableCursors: boolean;
47 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48 >                             Scrollable: boolean=false): IResultSet; overload;
49 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51 >                             params: array of const): IResultSet; overload;
52 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53 >                             params: array of const): IResultSet; overload;
54 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55 >                             params: array of const): IResultSet; overload;
56 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57 >                             Scrollable: boolean=false): IResultSet; overload;
58 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60 >                             params: array of const): IResultSet; overload;
61 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63 >                             params: array of const): IResultSet; overload;
64 >   IStatement:
65 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66 >   IResultSet:
67 >    function FetchPrior: boolean; {fetch previous record}
68 >    function FetchFirst:boolean; {fetch first record}
69 >    function FetchLast: boolean; {fetch last record}
70 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72 >    function IsBof: boolean;
73 >
74 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
75 >
76 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
77 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
78 >    output by the tokeniser will now use the platform specific lineEnding regardless
79 >    of whether the input uses the CRLF or LF as a line separator.
80 >
81 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
82 >
83 >
84 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
85 >
86 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
87 >
88 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
89 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
90 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
91 >   separate server interaction. This is intended as a performance optimisation.
92 >
93 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
94 >   IAttachment interface functions:
95 >
96 >    function GetInlineBlobLimit: integer;
97 >    procedure SetInlineBlobLimit(limit: integer);
98 >
99 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
100 >   user as the functionality is embedded in the implementation of the IStatement
101 >   interface. Three new functions are defined:
102 >
103 >    procedure AddToBatch;
104 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
105 >    procedure CancelBatch;
106 >    function GetBatchCompletion: IBatchCompletion;
107 >    function GetBatchRowLimit: integer;
108 >    procedure SetBatchRowLimit(aLimit: integer);
109 >
110 >   Also
111 >
112 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
113 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
114 >
115 >   For more information see the User Guide.
116 >
117 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
118 >   provided with the EIBInterBaseError now include all three parts.
119 >
120 > 5. Firebird.pas and include files updated to Firebird 4.0.0
121 >
122 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
123 >   Returns SQL Statement type as a text string;
124 >
125 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
126 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
127 >
128 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
129 >
130 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
131 >   typo in FB30Statement.pas that caused an unknown parameter error.
132 >
133 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
134 >
135 > 1. Imported (Firebird) constants updated for Firebird 4.
136 >
137 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
138 >
139 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
140 >
141 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
142 >
143 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
144 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
145 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
146 >   type safe access to the Firebird IMaster interface and avoids the need to turn
147 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
148 >
149 > 6. New IFirebirdAPI Calls:
150 >    function HasLocalTZDB: boolean;
151 >    function HasTimeZoneSupport: boolean;
152 >    function HasExtendedTZSupport: boolean;
153 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
154 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
155 >
156 > 7. New IAttachment Calls:
157 >    function HasDecFloatSupport: boolean;
158 >    function GetTimeZoneServices: ITimeZoneServices;
159 >    function HasTimeZoneSupport: boolean;
160 >
161 > 8. New Interface ITimeZoneServices.
162 >
163 > 9. New ISQLData API Calls:
164 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
165 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
166 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
167 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
168 >    function GetAsUTCDateTime: TDateTime;
169 >    function GetAsBCD: tBCD;
170 >
171 > 10. New ISQLParam API Calls
172 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
173 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

181 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
182 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
183 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
184 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
185 >    procedure SetAsBcd(aValue: tBCD);
186 >
187 > 11. New IArray API Calls
188 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
189 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

196 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
197 >
198 > 12. Utility functions in IBUtils
199 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
200 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;

205 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
206 >
207 > 13. IDPB, ITPB and ISPB: new interface method
208 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
209 >    This is used to add a parameter block item by the string equivalent of its
210 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
211 >
212 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
213 >      function getParamTypeName: AnsiString;
214 >
215 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a
216 >     SIGEVENT error when a programme using the embeded server is unloaded.
217 >
218 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
219 >
220 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
221 >   with a Firebrid 3 client library.
222 >
223 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
224 >    If a client library path is not explicitly provided and the FIREBIRD environment
225 >    variable is set then the directory given by this variable and any 'lib' subdirectory
226 >    are searched for the Firebird client library. Only if none is found, is the default
227 >    client library used.
228 >
229 > 3.  IUtil.FormatStatus now used to format error messages when using new API
230 >
231 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
232 >
233 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
234 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
235 >    that the byte length corresponds to the number of characters specified for the column.
236 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
237 >    correct behaviour but may affect some implementations that relied upon automatic
238 >    trimming of trailing white space.
239 >
240 > 6.  New IFirebirdAPI Calls:
241 >      function GetClientMajor: integer;
242 >      function GetClientMinor: integer;
243 >
244 > 7.  IColumnMetaData and IArrayMetaData: new method
245 >      function GetCharSetWidth: integer;
246 >
247 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
248 >
249 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
250 >   case sensitive
251 >
252 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
253 >
254 > 3. New API Calls:
255 >        IColumnMetaData.GetStatement
256 >        IColumnMetaData.GetTransaction
257 >        ISQLData.GetStrDataLength
258 >        IResults.GetStatement
259 >        IAttachment.OpenBlob (using Blob metadata)
260 >        IAttachment.OpenArray (using array metadata)
261 >
262 > 4. FBMessages: removal of unused messages
263 >
264 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
265 >
266 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
267 >
268 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
269 >
270 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
271 >   where the second character of the parameter name is a numeric.
272 >
273 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
274 >   This returns the isc_version connection information as one or more lines.
275 >   This is the same information as returned by isql with the -z option.
276 >
277 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
278 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
279 >   compiler option then the Firebird 3 API is no longer compiled in.
280 >
281 > 4. IColumnMetaData: new method.
282 >
283 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
284 >                        dfDateTime,   {SQL DATETIME}
285 >                        dfTime);
286 >
287 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
288 >
289 >   This returns the max. number of characters returned by the "AsString" method
290 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
291 >
292 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
293 >     CaseSensitiveParams: boolean = false
294 >
295 >   If this argument is set to true then SQL parameter names are assumed to be case
296 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
297 >   sensitive name.
298 >
299 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
300 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
301 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
302 >   using .AsString.

307 >
308 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
309 >
310 > 2. Restrict IsMultiThread check to Unix only for compatibility with
311 >   https://bugs.freepascal.org/view.php?id=30535
312 >
313 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
314 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
315 >   and processing internal parameters as statement parameters.
316 >
317 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
318 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
319 >
320 > 5. New function added to IB.pas
321 >
322 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
323 >
324 >   This allows a Firebird Library to be loaded from an explicit path. use the
325 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
326 >   the library. It is possible to load Firebird libraries from different locations
327 >   simultaneously, each with a distinct IFirebirdAPI.

330 >
331 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
332 >   program compiled with -CR command line switch.
333 >
334 > 2. IServiceManager additions (informational):
335 >    function getProtocol: TProtocol;
336 >    function getPortNo: AnsiString;
337 >
338 > 3. IServiceManager improved error handling. Interfaces changed:
339 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
340 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
341 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
342 >
343 > 4. IAttachment addition (informational)
344 >    function GetSecurityDatabase: AnsiString;
345 >
346 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
347 >   thus now returns accumulated stats for a select statement from opening a cursor
348 >   up to the last fetch.
349 >
350 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
351 >   the problem.
352 >
353 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
354 >   replaces deprecated "comp" type.
355 >
356 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
357 >
358 > 11. URL Connection Strings: inet4 and inet6 now recognised.
359 >
360 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
361 >
362 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.

367   1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
368  
# Line 19 | Line 383 | FBINTF Change Log  version
383        function GetRemoteProtocol: AnsiString;
384        function GetODSMajorVersion: integer;
385        function GetODSMinorVersion: integer;
386 +      function GetAuthenticationMethod: AnsiString;
387  
388     These results are cached when the connection is opened and hence do not
389     require a database lookup.

401  
402   9. IBUtils code tidy up.
403  
404 + 10. Parameter Block interfaces "find" method. As documented, this should have
405 +   returned a nil interface when the item could not be found. Instead, an empty
406 +   interface item was returned. "Find" now works as documented and will return
407 +   a nil interface if the item cannot be found.
408 +
