1 > FBINTF Change Log  version          (1.4-1 Build 14096) Sat, 21 Oct 2023 14:41:26 +0100
2 >
3 > 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
4 >   checks for range checking.
5 >
6 > 2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
7 >   any additional error information is decoded.
8 >
9 > 3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
10 >   charsetid is now preserved and size is set to default blob size. Now aligns with
11 >   FB3 and later.
12 >
13 > 4. DDL and DML string literals are now explicitly set to the connection character
14 >   set rather than the default character set provided by the compiler.
15 >
16 > 5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
17 >   now makes use of the RTL fpwidestring unit for support of international character
18 >   sets.
19 >
20 > 6. Database exception handling (see section 9.3 in user guide).
21 >    * For FB3 and later API: Connection Character set now applied to message returned
22 >      by fb_interpret and message then transliterated if necessary to the system character set.
23 >    * For Legacy API: The message character set is guessed as UTF8 unless invalid
24 >      UTF8 characters found when connection character set is assumed. Message then
25 >      transliterated if necessary to system character set.
26 >      Note: this difference of behaviour is because legacy API presents exception messages
27 >      "as is", while FB3 server attempts to transliterate to connection character set.
28 >
29 > FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
30 >
31 > 1. Support package fbudr added for support of User Defined Routines (UDRs), and package
32 >   fbudrtestbed for client side debugging of UDR libraries.
33 >
34 > 2. Package layout changed with introduction of udr support. IB*.pas files moved from
35 >    root directory to "client". IBHeader moved to "Client".
36 >
37 > 3. Delphi packages: all packages now compile .dcp and .bpi files to either
38 >   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
39 >   fbintf.dcp and fbintf.bpi files from other locations.
40 >
41 > 4. Client side journaling support added. Interface changes
42 >   IAttachment
43 >    function JournalingActive: boolean;
44 >    function GetJournalOptions: TJournalOptions;
45 >    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
46 >    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
47 >    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
48 >    procedure StopJournaling(RetainJournal: boolean);
49 >
50 > 5. Transactions may now be given a local transaction name:
51 >   IFirebirdAPI
52 >     function StartTransaction(Attachments: array of IAttachment;
53 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
54 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
55 >             aName: AnsiString=''): ITransaction; overload;
56 >     function StartTransaction(Attachments: array of IAttachment;
57 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
58 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
59 >             aName: AnsiString=''): ITransaction; overload;
60 >
61 >   IAttachment
62 >    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
63 >    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
64 >    function StartTransaction(TPB: array of byte;
65 >                              DefaultCompletion: TTransactionCompletion=taCommit;
66 >                              aName: AnsiString=''): ITransaction; overload;
67 >    function StartTransaction(TPB: ITPB;
68 >                              DefaultCompletion: TTransactionCompletion=taCommit;
69 >                              aName: AnsiString=''): ITransaction; overload;
70 >
71 >  ITransaction
72 >    function GetTransactionName: AnsiString;
73 >    procedure SetTransactionName(aValue: AnsiString);
74 >
75 > 6. Additional Transaction information
76 >     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
77 >
78 >   ITransaction
79 >     function GetDefaultCompletion: TTransactionCompletion;
80 >     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
81 >
82 > 7. New IAttachment helper functions
83 >     function HasTable(aTableName: AnsiString): boolean;
84 >     function HasFunction(aFunctionName: AnsiString): boolean;
85 >     function HasProcedure(aProcName: AnsiString): boolean;
86 >     function GetAttachmentID: integer;
87 >     function GetCharSetID: integer;
88 >
89 > 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
90 >   will be allocated for batch operations.
91 >
92 > 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
93 >    function GetStatement: IStatement;
94 >    function GetTransaction: ITransaction;
95 >    function GetAttachment: IAttachment;
96 >
97 > 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
98 >    interfaces.
99 >
100 > 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
101 >    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
102 >    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
103 >    of numerics without loss of precision.
104 >
105 > 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
106 >
107 > 13. ISQLParams new method "Clear"
108 >
109 > 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
110 >    request rather than on attachment connect.
111 >
112 > 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
113 >    fact that SQLCodes are soon to be deprecated. In the future, the other options
114 >    will be silently ignored if SQLCode support is not present in the Firebird
115 >    Client library.
116 >
117 > 16. ITransaction changes Rollback and Commit from procedures to functions:
118 >      function Commit(Force: boolean=false): TTrCompletionState;
119 >      function Rollback(Force: boolean=false): TTrCompletionState;
120 >
121 >    Specifically, this is to allow the functions to report back a failed commit or
122 >    rollback when Force = true. In the case, the transaction handle has been
123 >    released, while the transaction remains in limbo.
124 >
125 > 17. IAttachment ExecImmediate.
126 >    When the transaction parameters are provided as an array of const and the
127 >    statement fails, the transaction is rolledback (forced) before the exception
128 >    is raised.
129 >
130 > 18. In Firebird 3 and later API: the status vector is now a thread var, as was
131 >    already the case with the legacy API. Avoids problems when calling underlying
132 >    Firebird API in multiple threads.
133 >
134 > 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
135 >    reasons.
136 >
137 > 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
138 >
139 > 21. TSQLXMLReader: handle 'blob' as a reserved word
140 >
141 > 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
142 >
143 >
144 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
145 >
146 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
147 >
148 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
149 >   using remote protocol. Scrollable cursors with remote database expected to
150 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
151 >   a not supported error.
152 >
153 > 3. IStatement: new function;
154 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
155 >    TStatementFlags = set of TStatementFlag;
156 >    function GetFlags: TStatementFlags;
157 >
158 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
159 >   compatibility.
160 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
161 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
162 >   to be used with Update...Retruning statements that return a singleton row,
163 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
164 >   it will open the cursor and return the first row only.
165 >
166 > 5. ITransaction: new functions:
167 >    function GetIsReadOnly: boolean;
168 >    function GetTransactionID: integer;
169 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
170 >    function GetTrInformation(Request: byte): ITrInformation; overload;
171 >
172 >   The latter two return the Transaction Information block. The first two extract
173 >   information the Transaction Information block
174 >
175 > 6. New function TSQLTokeniser.ReadCharacters
176 >   Used internally.
177 >
178 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
179 >   parameter placeholders instead of named parameters.
180 >
181 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
182 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
183 >
184 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
185 >   used to get an IBError Message instead of isc_interprete.
186 >
187 > 10. Internal tidyup. Native code now used for decoding integers and the events
188 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
189 >    isc_event_block and isc_event_counts.
190 >
191 > 11. New IAttachment function
192 >     function GetAttachmentID: integer;
193 >
194 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
195 >    subclasses to enable UDR support.
196 >
197 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
198 >
199 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
200 >
201 > 2. IStatement: new methods:
202 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
203 >    function GetStaleReferenceChecks: boolean;
204 >
205 >   In previous versions, stale reference checks were always enabled. This allows the
206 >   user to disable them on a per statement basis. Note this can risk out-of-date
207 >   statement BLR. See User Guide.
208 >
209 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
210 >   stored procedure and hence avoids replacing named parameters within a containing
211 >   BEGIN..END block.
212 >
213 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
214 >   zero is now treated as a special case to avoid the risk of floating point
215 >   rounding errors affecting pure integers.
216 >
217 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
218 >
219 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
220 >   SQL Parameter metadata (methods moved from ISQLParam).
221 >
222 > 7. ISQLParam: new method
223 >     function getColMetadata: IParamMetaData;
224 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
225 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
226 >   setting a VARCHAR column to an integer value.
227 >
228 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
229 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
230 >   also IAttachment:
231 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
232 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
233 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
234 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
235 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
236 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
237 >                       GenerateParamNames: boolean=false;
238 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
239 >
240 > 9. Support for scrollable cursors added. New/updated methods:
241 >   IAttachment:
242 >    function HasScollableCursors: boolean;
243 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
244 >                             Scrollable: boolean=false): IResultSet; overload;
245 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
246 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
247 >                             params: array of const): IResultSet; overload;
248 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
249 >                             params: array of const): IResultSet; overload;
250 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
251 >                             params: array of const): IResultSet; overload;
252 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
253 >                             Scrollable: boolean=false): IResultSet; overload;
254 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
255 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
256 >                             params: array of const): IResultSet; overload;
257 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
258 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
259 >                             params: array of const): IResultSet; overload;
260 >   IStatement:
261 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
262 >   IResultSet:
263 >    function FetchPrior: boolean; {fetch previous record}
264 >    function FetchFirst:boolean; {fetch first record}
265 >    function FetchLast: boolean; {fetch last record}
266 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
267 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
268 >    function IsBof: boolean;
269 >
270 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
271 >
272 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
273 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
274 >    output by the tokeniser will now use the platform specific lineEnding regardless
275 >    of whether the input uses the CRLF or LF as a line separator.
276 >
277 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
278 >
279 >
280 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
281 >
282 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
283 >
284 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
285 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
286 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
287 >   separate server interaction. This is intended as a performance optimisation.
288 >
289 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
290 >   IAttachment interface functions:
291 >
292 >    function GetInlineBlobLimit: integer;
293 >    procedure SetInlineBlobLimit(limit: integer);
294 >
295 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
296 >   user as the functionality is embedded in the implementation of the IStatement
297 >   interface. Three new functions are defined:
298 >
299 >    procedure AddToBatch;
300 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
301 >    procedure CancelBatch;
302 >    function GetBatchCompletion: IBatchCompletion;
303 >    function GetBatchRowLimit: integer;
304 >    procedure SetBatchRowLimit(aLimit: integer);
305 >
306 >   Also
307 >
308 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
309 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
310 >
311 >   For more information see the User Guide.
312 >
313 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
314 >   provided with the EIBInterBaseError now include all three parts.
315 >
316 > 5. Firebird.pas and include files updated to Firebird 4.0.0
317 >
318 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
319 >   Returns SQL Statement type as a text string;
320 >
321 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
322 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
323 >
324 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
325 >
326 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
327 >   typo in FB30Statement.pas that caused an unknown parameter error.
328 >
329 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
