1 + FBINTF Change Log  version          (1.4-0 Build 12952) Tue, 07 Dec 2021 11:53:46 +0000
2 +
3 + 1. Client side journaling support added. Interface changes
4 +   IAttachment
5 +    function JournalingActive: boolean;
6 +    function GetJournalOptions: TJournalOptions;
7 +    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
8 +    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
9 +    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
10 +    procedure StopJournaling(RetainJournal: boolean);
11 +
12 + 2. Transactions may now be given a local transaction name:
13 +   IFirebirdAPI
14 +     function StartTransaction(Attachments: array of IAttachment;
15 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
16 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
17 +             aName: AnsiString=''): ITransaction; overload;
18 +     function StartTransaction(Attachments: array of IAttachment;
19 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
20 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
21 +             aName: AnsiString=''): ITransaction; overload;
22 +
23 +   IAttachment
24 +    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
25 +    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
26 +    function StartTransaction(TPB: array of byte;
27 +                              DefaultCompletion: TTransactionCompletion=taCommit;
28 +                              aName: AnsiString=''): ITransaction; overload;
29 +    function StartTransaction(TPB: ITPB;
30 +                              DefaultCompletion: TTransactionCompletion=taCommit;
31 +                              aName: AnsiString=''): ITransaction; overload;
32 +
33 +  ITransaction
34 +    function GetTransactionName: AnsiString;
35 +    procedure SetTransactionName(aValue: AnsiString);
36 +
37 + 3. Additional Transaction information
38 +     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
39 +
40 +   ITransaction
41 +     function GetDefaultCompletion: TTransactionCompletion;
42 +     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
43 +
44 + 4. New IAttachment helper functions
45 +     function HasTable(aTableName: AnsiString): boolean;
46 +     function HasFunction(aFunctionName: AnsiString): boolean;
47 +     function HasProcedure(aProcName: AnsiString): boolean;
48 +     function GetAttachmentID: integer;
49 +     function GetCharSetID: integer;
50 +
51 + 5. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
52 +   will be allocted for batch operations.
53 +
54 + 6. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
55 +    function GetStatement: IStatement;
56 +    function GetTransaction: ITransaction;
57 +    function GetAttachment: IAttachment;
58 +
59 + 7. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
60 +   interfaces.
61 +
62 + 8. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
63 +   and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
64 +   functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
65 +   of numerics without loss of precision.
66 +
67 + 9. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
68 +
69 + 10. ISQLParams new method "Clear"
70 +
71 + 11. Support package fbudr added for support of User Defined Routines (UDRs).
72 +
73 + 12. Package layout changed with introduction of udr support. IB*.pas files moved from
74 +    root directory to "client".
75 +
76 +
77 + FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
78 +
79 + 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
80 +
81 + 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
82 +   using remote protocol. Scrollable cursors with remote database expected to
83 +   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
84 +   a not supported error.
85 +
86 + 3. IStatement: new function;
87 +    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
88 +    TStatementFlags = set of TStatementFlag;
89 +    function GetFlags: TStatementFlags;
90 +
91 + 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
92 +   compatibility.
93 +   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
94 +   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
95 +   to be used with Update...Retruning statements that return a singleton row,
96 +   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
97 +   it will open the cursor and return the first row only.
98 +
99 + 5. ITransaction: new functions:
100 +    function GetIsReadOnly: boolean;
101 +    function GetTransactionID: integer;
102 +    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
103 +    function GetTrInformation(Request: byte): ITrInformation; overload;
104 +
105 +   The latter two return the Transaction Information block. The first two extract
106 +   information the Transaction Information block
107 +
108 + 6. New function TSQLTokeniser.ReadCharacters
109 +   Used internally.
110 +
111 + 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
112 +   parameter placeholders instead of named parameters.
113 +
114 + 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
115 +   transaction handle is now ignored if Rollback/Commit is called with Force=true
116 +
117 + 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
118 +   used to get an IBError Message instead of isc_interprete.
119 +
120 + 10. Internal tidyup. Native code now used for decoding integers and the events
121 +    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
122 +    isc_event_block and isc_event_counts.
123 +
124 + 11. New IAttachment function
125 +     function GetAttachmentID: integer;
126 +
127 + 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
128 +    subclasses to enable UDR support.
129 +
130 + FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
131 +
132 + 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
133 +
134 + 2. IStatement: new methods:
135 +    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
136 +    function GetStaleReferenceChecks: boolean;
137 +
138 +   In previous versions, stale reference checks were always enabled. This allows the
139 +   user to disable them on a per statement basis. Note this can risk out-of-date
140 +   statement BLR. See User Guide.
141 +
142 + 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
143 +   stored procedure and hence avoids replacing named parameters within a containing
144 +   BEGIN..END block.
145 +
146 + 4. ISQLParam: using a string value to set an integer field with a scale factor of
147 +   zero is now treated as a special case to avoid the risk of floating point
148 +   rounding errors affecting pure integers.
149 +
150 + 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
151 +
152 + 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
153 +   SQL Parameter metadata (methods moved from ISQLParam).
154 +
155 + 7. ISQLParam: new method
156 +     function getColMetadata: IParamMetaData;
157 +   This instance of IParamMetaData returns the original column metadata which is unmutable.
158 +   Note: ISQLParam metadata can change after a parameter value has been set e.g when
159 +   setting a VARCHAR column to an integer value.
160 +
161 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
162 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
163 +   also IAttachment:
164 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
165 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
166 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
167 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
168 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
169 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
170 +                       GenerateParamNames: boolean=false;
171 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
172 +
173 + 9. Support for scrollable cursors added. New/updated methods:
174 +   IAttachment:
175 +    function HasScollableCursors: boolean;
176 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
177 +                             Scrollable: boolean=false): IResultSet; overload;
178 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
179 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
180 +                             params: array of const): IResultSet; overload;
181 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
182 +                             params: array of const): IResultSet; overload;
183 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
184 +                             params: array of const): IResultSet; overload;
185 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
186 +                             Scrollable: boolean=false): IResultSet; overload;
187 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
188 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
189 +                             params: array of const): IResultSet; overload;
190 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
191 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
192 +                             params: array of const): IResultSet; overload;
193 +   IStatement:
194 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
195 +   IResultSet:
196 +    function FetchPrior: boolean; {fetch previous record}
197 +    function FetchFirst:boolean; {fetch first record}
198 +    function FetchLast: boolean; {fetch last record}
199 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
200 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
201 +    function IsBof: boolean;
202 +
203 + 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
204 +
205 + 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
206 +    may be noticeable when a line separator occurs inside quoted text. The quoted text
207 +    output by the tokeniser will now use the platform specific lineEnding regardless
208 +    of whether the input uses the CRLF or LF as a line separator.
209 +
210 + 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
211 +
212 +
213 + FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
214 +
215 + 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
216 +
217 + 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
218 +   will now be encoded inline (i.e. as part of the parameter buffer) if they are
219 +   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
220 +   separate server interaction. This is intended as a performance optimisation.
221 +
222 +   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
223 +   IAttachment interface functions:
224 +
225 +    function GetInlineBlobLimit: integer;
226 +    procedure SetInlineBlobLimit(limit: integer);
227 +
228 + 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
229 +   user as the functionality is embedded in the implementation of the IStatement
230 +   interface. Three new functions are defined:
231 +
232 +    procedure AddToBatch;
233 +    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
234 +    procedure CancelBatch;
235 +    function GetBatchCompletion: IBatchCompletion;
236 +    function GetBatchRowLimit: integer;
237 +    procedure SetBatchRowLimit(aLimit: integer);
238 +
239 +   Also
240 +
241 +    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
242 +    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
243 +
244 +   For more information see the User Guide.
245 +
246 + 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
247 +   provided with the EIBInterBaseError now include all three parts.
248 +
249 + 5. Firebird.pas and include files updated to Firebird 4.0.0
250 +
251 + 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
252 +   Returns SQL Statement type as a text string;
253 +
254 + 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
255 +   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
256 +
257 + FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
258 +
259 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
260 +   typo in FB30Statement.pas that caused an unknown parameter error.
261 +
262 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
263 +
264 + 1. Imported (Firebird) constants updated for Firebird 4.
265 +
266 + 2. Firebird.pas from Firebird 4 integrated into source code tree.
267 +
268 + 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
269 +
270 + 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
271 +
272 + 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
273 +   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
274 +   interface provides a single method "function GetIMasterIntf: IMaster". This provides
275 +   type safe access to the Firebird IMaster interface and avoids the need to turn
276 +   off object checks when coercing "function GetIMaster: TObject" to IMaster.
277 +
278 + 6. New IFirebirdAPI Calls:
279 +    function HasLocalTZDB: boolean;
280 +    function HasTimeZoneSupport: boolean;
281 +    function HasExtendedTZSupport: boolean;
282 +    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
283 +    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
284 +
285 + 7. New IAttachment Calls:
286 +    function HasDecFloatSupport: boolean;
287 +    function GetTimeZoneServices: ITimeZoneServices;
288 +    function HasTimeZoneSupport: boolean;
289 +
290 + 8. New Interface ITimeZoneServices.
291 +
292 + 9. New ISQLData API Calls:
293 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
294 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
295 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
296 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
297 +    function GetAsUTCDateTime: TDateTime;
298 +    function GetAsBCD: tBCD;
299 +
300 + 10. New ISQLParam API Calls
301 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
302 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
303 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
304 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
305 +    function GetAsUTCDateTime: TDateTime;
306 +    function GetAsBCD: tBCD;
307 +    function GetStatement: IStatement;
308 +    function GetTransaction: ITransaction;
309 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
310 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
311 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
312 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
313 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
314 +    procedure SetAsBcd(aValue: tBCD);
315 +
316 + 11. New IArray API Calls
317 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
318 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
319 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
320 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
321 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
322 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
323 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
324 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
325 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
326 +
327 + 12. Utility functions in IBUtils
328 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
329 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
330 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
331 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
332 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
333 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
334 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
335 +
336 + 13. IDPB, ITPB and ISPB: new interface method
337 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
338 +    This is used to add a parameter block item by the string equivalent of its
339 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
340 +
341 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
342 +      function getParamTypeName: AnsiString;
343 +
344 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
345 +     SIGEVENT error when a programme using the embeded server is unloaded.
346 +
