1 > FBINTF Change Log  version          (1.3-2 Build 12798) Mon, 20 Sep 2021 12:42:46 +0100
2 >
3 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4 >
5 > 2. IStatement: new methods:
6 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7 >    function GetStaleReferenceChecks: boolean;
8 >
9 >   In previous versions, stale reference checks were always enabled. This allows the
10 >   user to disable them on a per statement basis. Note this can risk out-of-date
11 >   statement BLR. See User Guide.

13 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
14 >
15 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
16 >
17 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
18 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
19 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
20 >   separate server interaction. This is intended as a performance optimisation.
21 >
22 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
23 >   IAttachment interface functions:
24 >
25 >    function GetInlineBlobLimit: integer;
26 >    procedure SetInlineBlobLimit(limit: integer);
27 >
28 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
29 >   user as the functionality is embedded in the implementation of the IStatement
30 >   interface. Three new functions are defined:
31 >
32 >    procedure AddToBatch;
33 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
34 >    procedure CancelBatch;
35 >    function GetBatchCompletion: IBatchCompletion;
36 >    function GetBatchRowLimit: integer;
37 >    procedure SetBatchRowLimit(aLimit: integer);
38 >
39 >   Also
40 >
41 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
42 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
43 >
44 >   For more information see the User Guide.
45 >
46 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
47 >   provided with the EIBInterBaseError now include all three parts.
48 >
49 > 5. Firebird.pas and include files updated to Firebird 4.0.0
50 >
51 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
52 >   Returns SQL Statement type as a text string;
53 >
54 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
55 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
56 >
57 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
58 >
59 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
60 >   typo in FB30Statement.pas that caused an unknown parameter error.
61 >
62 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
63 >
64 > 1. Imported (Firebird) constants updated for Firebird 4.
65 >
66 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
67 >
68 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
69 >
70 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
71 >
72 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
73 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
74 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
75 >   type safe access to the Firebird IMaster interface and avoids the need to turn
76 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
77 >
78 > 6. New IFirebirdAPI Calls:
79 >    function HasLocalTZDB: boolean;
80 >    function HasTimeZoneSupport: boolean;
81 >    function HasExtendedTZSupport: boolean;
82 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
83 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
84 >
85 > 7. New IAttachment Calls:
86 >    function HasDecFloatSupport: boolean;
87 >    function GetTimeZoneServices: ITimeZoneServices;
88 >    function HasTimeZoneSupport: boolean;
89 >
90 > 8. New Interface ITimeZoneServices.
91 >
92 > 9. New ISQLData API Calls:
93 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
94 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
95 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
96 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
97 >    function GetAsUTCDateTime: TDateTime;
98 >    function GetAsBCD: tBCD;
99 >
100 > 10. New ISQLParam API Calls
101 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
102 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

106 >    function GetAsBCD: tBCD;
107 >    function GetStatement: IStatement;
108 >    function GetTransaction: ITransaction;
109 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
110 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
111 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
112 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
113 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
114 >    procedure SetAsBcd(aValue: tBCD);
115 >
116 > 11. New IArray API Calls
117 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
118 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
119 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

137 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
138 >    This is used to add a parameter block item by the string equivalent of its
139 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
140 >
141 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
142 >      function getParamTypeName: AnsiString;
143 >
144 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a

146 >
147 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
148 >
149 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
150 >   with a Firebrid 3 client library.
151 >
152 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
153 >    If a client library path is not explicitly provided and the FIREBIRD environment
154 >    variable is set then the directory given by this variable and any 'lib' subdirectory
155 >    are searched for the Firebird client library. Only if none is found, is the default
156 >    client library used.
157 >
158 > 3.  IUtil.FormatStatus now used to format error messages when using new API
159 >
160 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
161 >
162 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
163 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
164 >    that the byte length corresponds to the number of characters specified for the column.
165 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
166 >    correct behaviour but may affect some implementations that relied upon automatic
167 >    trimming of trailing white space.
168 >
169 > 6.  New IFirebirdAPI Calls:
170 >      function GetClientMajor: integer;
171 >      function GetClientMinor: integer;
172 >
173 > 7.  IColumnMetaData and IArrayMetaData: new method
174 >      function GetCharSetWidth: integer;
175 >
176 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
177 >
178 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
179 >   case sensitive
180 >
181 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
182 >
183 > 3. New API Calls:
184 >        IColumnMetaData.GetStatement
185 >        IColumnMetaData.GetTransaction
186 >        ISQLData.GetStrDataLength
187 >        IResults.GetStatement
188 >        IAttachment.OpenBlob (using Blob metadata)
189 >        IAttachment.OpenArray (using array metadata)
190 >
191 > 4. FBMessages: removal of unused messages
192 >
193 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
194 >
195 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
196 >
197 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
198 >
199 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
200 >   where the second character of the parameter name is a numeric.
201 >
202 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
203 >   This returns the isc_version connection information as one or more lines.
204 >   This is the same information as returned by isql with the -z option.
205 >
206 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
207 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
208 >   compiler option then the Firebird 3 API is no longer compiled in.
209 >
210 > 4. IColumnMetaData: new method.
211 >
212 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
213 >                        dfDateTime,   {SQL DATETIME}
214 >                        dfTime);
215 >
216 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
217 >
218 >   This returns the max. number of characters returned by the "AsString" method
219 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
220 >
221 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
222 >     CaseSensitiveParams: boolean = false
223 >
224 >   If this argument is set to true then SQL parameter names are assumed to be case
225 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
226 >   sensitive name.
227 >
228 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
229 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
230 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
231 >   using .AsString.
232 >

235 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
236 >
237 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
238 >
239 > 2. Restrict IsMultiThread check to Unix only for compatibility with
240 >   https://bugs.freepascal.org/view.php?id=30535
241 >
242 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
243 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
244 >   and processing internal parameters as statement parameters.
245 >
246 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
247 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
248 >
249 > 5. New function added to IB.pas
250 >
251 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
252 >
253 >   This allows a Firebird Library to be loaded from an explicit path. use the
254 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
255 >   the library. It is possible to load Firebird libraries from different locations
256 >   simultaneously, each with a distinct IFirebirdAPI.
257 >
258 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
259 >
260 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
261 >   program compiled with -CR command line switch.
262 >
263 > 2. IServiceManager additions (informational):
264 >    function getProtocol: TProtocol;
265 >    function getPortNo: AnsiString;
266 >
267 > 3. IServiceManager improved error handling. Interfaces changed:
268 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
269 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
270 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
271 >
272 > 4. IAttachment addition (informational)
273 >    function GetSecurityDatabase: AnsiString;
274 >
275 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
276 >   thus now returns accumulated stats for a select statement from opening a cursor
277 >   up to the last fetch.
278 >
279 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
280 >   the problem.
281 >
282 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
283 >   replaces deprecated "comp" type.
284 >
285 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
286 >
287 > 11. URL Connection Strings: inet4 and inet6 now recognised.
288 >
289 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
290 >
291 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
292 >
293 >
294 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
295 >
296 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
297 >
298 > 2. IAttachment: add two new methods
299 >     function HasDefaultCharSet: boolean;
300 >     function GetDefaultCharSetID: integer;
301 >
302 >   These return, respectively, true if a connection default character set was
303 >   specified and the character set id of the connection default character set.
304 >   The DefaultCharSetID is cached when the connection is opened and hence does not
305 >   require a database lookup.
306 >
307 > 3. Avoid exception when a text blob is a stored procedure parameter.
308 >
309 > 4. Update test suite to include a test for a stored proc returning a text blob.
310 >
311 > 5. IAttachment: add
312 >      function GetRemoteProtocol: AnsiString;
313 >      function GetODSMajorVersion: integer;
314 >      function GetODSMinorVersion: integer;
315 >      function GetAuthenticationMethod: AnsiString;
316 >
317 >   These results are cached when the connection is opened and hence do not
318 >   require a database lookup.
319 >
320 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
321 >   connect string used to create/connect to the database.
322 >
323 > 7. IAttachment: Create Database using SQL statement. The username and password
324 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
325 >   It is now possible to use IAttachment disconnect/connect to reconnect to
326 >   a database for which the initial connection was established by a create
327 >   database sql statement. Available in FPC only.
328 >
329 > 8. Update Test 1 to test 5, 6 and 7 above.
330 >
331 > 9. IBUtils code tidy up.
332 >
333 > 10. Parameter Block interfaces "find" method. As documented, this should have
334 >   returned a nil interface when the item could not be found. Instead, an empty
335 >   interface item was returned. "Find" now works as documented and will return
336 >   a nil interface if the item cannot be found.
337 >
338 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
339 >
340 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
341 >    requests with additional parameters. This is to enable support for fb_info_page_contents
342 >    (return of page contents). Response to fb_info_page_contents returned as
343 >    a string with code page CP_NONE.
344 >
345 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
346 >    test suite updated.
347 >
348 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
349 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
350 >
351 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
352 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
353 >    default connection port to be specified.
354 >
