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". IBHeader move to "Client".
75 +
76 + 13. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
77 +    request rather than on attachment connect.
78 +
79 +
80 + FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
81 +
82 + 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
83 +
84 + 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
85 +   using remote protocol. Scrollable cursors with remote database expected to
86 +   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
87 +   a not supported error.
88 +
89 + 3. IStatement: new function;
90 +    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
91 +    TStatementFlags = set of TStatementFlag;
92 +    function GetFlags: TStatementFlags;
93 +
94 + 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
95 +   compatibility.
96 +   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
97 +   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
98 +   to be used with Update...Retruning statements that return a singleton row,
99 +   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
100 +   it will open the cursor and return the first row only.
101 +
102 + 5. ITransaction: new functions:
103 +    function GetIsReadOnly: boolean;
104 +    function GetTransactionID: integer;
105 +    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
106 +    function GetTrInformation(Request: byte): ITrInformation; overload;
107 +
108 +   The latter two return the Transaction Information block. The first two extract
109 +   information the Transaction Information block
110 +
111 + 6. New function TSQLTokeniser.ReadCharacters
112 +   Used internally.
113 +
114 + 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
115 +   parameter placeholders instead of named parameters.
116 +
117 + 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
118 +   transaction handle is now ignored if Rollback/Commit is called with Force=true
119 +
120 + 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
121 +   used to get an IBError Message instead of isc_interprete.
122 +
123 + 10. Internal tidyup. Native code now used for decoding integers and the events
124 +    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
125 +    isc_event_block and isc_event_counts.
126 +
127 + 11. New IAttachment function
128 +     function GetAttachmentID: integer;
129 +
130 + 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
131 +    subclasses to enable UDR support.
132 +
133 + FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
134 +
135 + 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
136 +
137 + 2. IStatement: new methods:
138 +    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
139 +    function GetStaleReferenceChecks: boolean;
140 +
141 +   In previous versions, stale reference checks were always enabled. This allows the
142 +   user to disable them on a per statement basis. Note this can risk out-of-date
143 +   statement BLR. See User Guide.
144 +
145 + 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
146 +   stored procedure and hence avoids replacing named parameters within a containing
147 +   BEGIN..END block.
148 +
149 + 4. ISQLParam: using a string value to set an integer field with a scale factor of
150 +   zero is now treated as a special case to avoid the risk of floating point
151 +   rounding errors affecting pure integers.
152 +
153 + 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
154 +
155 + 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
156 +   SQL Parameter metadata (methods moved from ISQLParam).
157 +
158 + 7. ISQLParam: new method
159 +     function getColMetadata: IParamMetaData;
160 +   This instance of IParamMetaData returns the original column metadata which is unmutable.
161 +   Note: ISQLParam metadata can change after a parameter value has been set e.g when
162 +   setting a VARCHAR column to an integer value.
163 +
164 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
165 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
166 +   also IAttachment:
167 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
168 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
169 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
170 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
171 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
172 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
173 +                       GenerateParamNames: boolean=false;
174 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
175 +
176 + 9. Support for scrollable cursors added. New/updated methods:
177 +   IAttachment:
178 +    function HasScollableCursors: boolean;
179 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
180 +                             Scrollable: boolean=false): IResultSet; overload;
181 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
182 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
183 +                             params: array of const): IResultSet; overload;
184 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
185 +                             params: array of const): IResultSet; overload;
186 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
187 +                             params: array of const): IResultSet; overload;
188 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
189 +                             Scrollable: boolean=false): IResultSet; overload;
190 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
191 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
192 +                             params: array of const): IResultSet; overload;
193 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
194 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
195 +                             params: array of const): IResultSet; overload;
196 +   IStatement:
197 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
198 +   IResultSet:
199 +    function FetchPrior: boolean; {fetch previous record}
200 +    function FetchFirst:boolean; {fetch first record}
201 +    function FetchLast: boolean; {fetch last record}
202 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
203 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
204 +    function IsBof: boolean;
205 +
206 + 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
207 +
208 + 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
209 +    may be noticeable when a line separator occurs inside quoted text. The quoted text
210 +    output by the tokeniser will now use the platform specific lineEnding regardless
211 +    of whether the input uses the CRLF or LF as a line separator.
212 +
213 + 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
214 +
215 +

217  
218   1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
