2 >
3 > 1. Imported (Firebird) constants updated for Firebird 4.
4 >
5 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
6 >
7 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
8 >
9 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
10 >
11 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
12 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
13 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
14 >   type safe access to the Firebird IMaster interface and avoids the need to turn
15 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
16 >
17 > 6. New IFirebirdAPI Calls:
18 >    function HasLocalTZDB: boolean;
19 >    function HasTimeZoneSupport: boolean;
20 >    function HasExtendedTZSupport: boolean;
21 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
22 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
23 >
24 > 7. New IAttachment Calls:
25 >    function HasDecFloatSupport: boolean;
26 >    function GetTimeZoneServices: ITimeZoneServices;
27 >    function HasTimeZoneSupport: boolean;
28 >
29 > 8. New Interface ITimeZoneServices.
30 >
31 > 9. New ISQLData API Calls:
32 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
33 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
34 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
35 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
36 >    function GetAsUTCDateTime: TDateTime;
37 >    function GetAsBCD: tBCD;
38 >
39 > 10. New ISQLParam API Calls
40 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
41 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
42 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
43 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
44 >    function GetAsUTCDateTime: TDateTime;
45 >    function GetAsBCD: tBCD;
46 >    function GetStatement: IStatement;
47 >    function GetTransaction: ITransaction;
48 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;

51 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
52 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
53 >    procedure SetAsBcd(aValue: tBCD);
54 >
55 > 11. New IArray API Calls
56 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
57 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
58 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

79 >
80 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
81 >      function getParamTypeName: AnsiString;

85 >
86 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
87 >
88 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
89 >   with a Firebrid 3 client library.
90 >
91 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
92 >    If a client library path is not explicitly provided and the FIREBIRD environment
93 >    variable is set then the directory given by this variable and any 'lib' subdirectory
94 >    are searched for the Firebird client library. Only if none is found, is the default
95 >    client library used.
96 >
97 > 3.  IUtil.FormatStatus now used to format error messages when using new API
98 >
99 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
100 >
101 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
102 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
103 >    that the byte length corresponds to the number of characters specified for the column.
104 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
105 >    correct behaviour but may affect some implementations that relied upon automatic
106 >    trimming of trailing white space.
107 >
108 > 6.  New IFirebirdAPI Calls:
109 >      function GetClientMajor: integer;
110 >      function GetClientMinor: integer;
111 >
112 > 7.  IColumnMetaData and IArrayMetaData: new method
113 >      function GetCharSetWidth: integer;
114 >
115 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
116 >
117 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
118 >   case sensitive
119 >
120 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
121 >
122 > 3. New API Calls:
123 >        IColumnMetaData.GetStatement
124 >        IColumnMetaData.GetTransaction
125 >        ISQLData.GetStrDataLength
126 >        IResults.GetStatement
127 >        IAttachment.OpenBlob (using Blob metadata)
128 >        IAttachment.OpenArray (using array metadata)
129 >
130 > 4. FBMessages: removal of unused messages
131 >
132 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
133 >
134 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
135 >
136 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
137 >
138 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
139 >   where the second character of the parameter name is a numeric.
140 >
141 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
142 >   This returns the isc_version connection information as one or more lines.
143 >   This is the same information as returned by isql with the -z option.
144 >
145 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
146 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
147 >   compiler option then the Firebird 3 API is no longer compiled in.
148 >
149 > 4. IColumnMetaData: new method.
150 >
151 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
152 >                        dfDateTime,   {SQL DATETIME}
153 >                        dfTime);
154 >
155 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
156 >
157 >   This returns the max. number of characters returned by the "AsString" method
158 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
159 >
160 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
161 >     CaseSensitiveParams: boolean = false
162 >
163 >   If this argument is set to true then SQL parameter names are assumed to be case
164 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
165 >   sensitive name.
166 >
167 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
168 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
169 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
170 >   using .AsString.

174 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
175 >
176 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
177 >
178 > 2. Restrict IsMultiThread check to Unix only for compatibility with
179 >   https://bugs.freepascal.org/view.php?id=30535
180 >
181 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
182 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
183 >   and processing internal parameters as statement parameters.
184 >
185 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
186 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
187 >
188 > 5. New function added to IB.pas
189 >
190 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
191 >
192 >   This allows a Firebird Library to be loaded from an explicit path. use the
193 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
194 >   the library. It is possible to load Firebird libraries from different locations
195 >   simultaneously, each with a distinct IFirebirdAPI.
196 >
197 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
198 >
199 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
200 >   program compiled with -CR command line switch.
201 >
202 > 2. IServiceManager additions (informational):
203 >    function getProtocol: TProtocol;
204 >    function getPortNo: AnsiString;
205 >
206 > 3. IServiceManager improved error handling. Interfaces changed:
207 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
208 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
209 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
210 >
211 > 4. IAttachment addition (informational)
212 >    function GetSecurityDatabase: AnsiString;
213 >
214 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
215 >   thus now returns accumulated stats for a select statement from opening a cursor
216 >   up to the last fetch.
217 >
218 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
219 >   the problem.
220 >
221 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
222 >   replaces deprecated "comp" type.
223 >
224 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
225 >
226 > 11. URL Connection Strings: inet4 and inet6 now recognised.
227 >
228 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
229 >
230 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
231 >
