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.

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 >
