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 Note this can risk out-of-date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.
12 >
13 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14 >   stored procedure and hence avoids replacing named parameters within a containing
15 >   BEGIN..END block.
16 >
17 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 >   zero is now treated as a special case to avoid the risk of floating point
19 >   rounding errors affecting pure integers.
20 >
21 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22 >
23 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 >   SQL Parameter metadata (methods moved from ISQLParam).
25 >
26 > 7. ISQLParam: new method
27 >     function getColMetadata: IParamMetaData;
28 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
29 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 >   setting a VARCHAR column to an integer value.
31 >
32 >
33 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
34 >
35 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
36 >
37 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
38 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
39 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
40 >   separate server interaction. This is intended as a performance optimisation.
41 >
42 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
43 >   IAttachment interface functions:
44 >
45 >    function GetInlineBlobLimit: integer;
46 >    procedure SetInlineBlobLimit(limit: integer);
47 >
48 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
49 >   user as the functionality is embedded in the implementation of the IStatement
50 >   interface. Three new functions are defined:
51 >
52 >    procedure AddToBatch;
53 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
54 >    procedure CancelBatch;
55 >    function GetBatchCompletion: IBatchCompletion;
56 >    function GetBatchRowLimit: integer;
57 >    procedure SetBatchRowLimit(aLimit: integer);
58 >
59 >   Also
60 >
61 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
62 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
63 >
64 >   For more information see the User Guide.
65 >
66 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
67 >   provided with the EIBInterBaseError now include all three parts.
68 >
69 > 5. Firebird.pas and include files updated to Firebird 4.0.0
70 >
71 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
72 >   Returns SQL Statement type as a text string;
73 >
74 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
75 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
76 >
77 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
78 >
79 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
80 >   typo in FB30Statement.pas that caused an unknown parameter error.
81 >
82 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
83 >
84 > 1. Imported (Firebird) constants updated for Firebird 4.
85 >
86 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
87 >
88 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
89 >
90 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
91 >
92 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
93 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
94 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
95 >   type safe access to the Firebird IMaster interface and avoids the need to turn
96 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
97 >
98 > 6. New IFirebirdAPI Calls:
99 >    function HasLocalTZDB: boolean;
100 >    function HasTimeZoneSupport: boolean;
101 >    function HasExtendedTZSupport: boolean;
102 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
103 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
104 >
105 > 7. New IAttachment Calls:
106 >    function HasDecFloatSupport: boolean;
107 >    function GetTimeZoneServices: ITimeZoneServices;
108 >    function HasTimeZoneSupport: boolean;
109 >
110 > 8. New Interface ITimeZoneServices.
111 >
112 > 9. New ISQLData API Calls:
113 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
114 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
115 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
116 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
117 >    function GetAsUTCDateTime: TDateTime;
118 >    function GetAsBCD: tBCD;
119 >
120 > 10. New ISQLParam API Calls
121 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;

133 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
134 >    procedure SetAsBcd(aValue: tBCD);
135 >
136 > 11. New IArray API Calls
137 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
138 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

145 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
146 >
147 > 12. Utility functions in IBUtils
148 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
149 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;

154 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
155 >
156 > 13. IDPB, ITPB and ISPB: new interface method
157 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
158 >    This is used to add a parameter block item by the string equivalent of its
159 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
160 >
161 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
162 >      function getParamTypeName: AnsiString;
163 >
164 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a
165 >     SIGEVENT error when a programme using the embeded server is unloaded.
166 >
167 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
168 >
169 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
170 >   with a Firebrid 3 client library.
171 >
172 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
173 >    If a client library path is not explicitly provided and the FIREBIRD environment
174 >    variable is set then the directory given by this variable and any 'lib' subdirectory
175 >    are searched for the Firebird client library. Only if none is found, is the default
176 >    client library used.
177 >
178 > 3.  IUtil.FormatStatus now used to format error messages when using new API
179 >
180 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
181 >
182 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
183 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
184 >    that the byte length corresponds to the number of characters specified for the column.
185 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
186 >    correct behaviour but may affect some implementations that relied upon automatic
187 >    trimming of trailing white space.
188 >
189 > 6.  New IFirebirdAPI Calls:
190 >      function GetClientMajor: integer;
191 >      function GetClientMinor: integer;
192 >
193 > 7.  IColumnMetaData and IArrayMetaData: new method
194 >      function GetCharSetWidth: integer;
195 >
196 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
197 >
198 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
199 >   case sensitive
200 >
201 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
202 >
203 > 3. New API Calls:
204 >        IColumnMetaData.GetStatement
205 >        IColumnMetaData.GetTransaction
206 >        ISQLData.GetStrDataLength
207 >        IResults.GetStatement
208 >        IAttachment.OpenBlob (using Blob metadata)
209 >        IAttachment.OpenArray (using array metadata)
210 >
211 > 4. FBMessages: removal of unused messages
212 >
213 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
214 >
215 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
216 >
217 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
218 >
219 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
220 >   where the second character of the parameter name is a numeric.
221 >
222 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
223 >   This returns the isc_version connection information as one or more lines.
224 >   This is the same information as returned by isql with the -z option.
225 >
226 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
227 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
228 >   compiler option then the Firebird 3 API is no longer compiled in.
229 >
230 > 4. IColumnMetaData: new method.
231 >
232 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
233 >                        dfDateTime,   {SQL DATETIME}
234 >                        dfTime);
235 >
236 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
237 >
238 >   This returns the max. number of characters returned by the "AsString" method
239 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
240 >
241 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
242 >     CaseSensitiveParams: boolean = false
243 >
244 >   If this argument is set to true then SQL parameter names are assumed to be case
245 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
246 >   sensitive name.
247 >
248 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
249 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
250 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
251 >   using .AsString.

255 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
256 >
257 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
258 >
259 > 2. Restrict IsMultiThread check to Unix only for compatibility with
260 >   https://bugs.freepascal.org/view.php?id=30535
261 >
262 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
263 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
264 >   and processing internal parameters as statement parameters.
265 >
266 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
267 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
268 >
269 > 5. New function added to IB.pas
270 >
271 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
272 >
273 >   This allows a Firebird Library to be loaded from an explicit path. use the
274 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
275 >   the library. It is possible to load Firebird libraries from different locations
276 >   simultaneously, each with a distinct IFirebirdAPI.
277 >
278 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
279 >
280 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
281 >   program compiled with -CR command line switch.
282 >
283 > 2. IServiceManager additions (informational):
284 >    function getProtocol: TProtocol;
285 >    function getPortNo: AnsiString;
286 >
287 > 3. IServiceManager improved error handling. Interfaces changed:
288 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
289 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
290 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
291 >
292 > 4. IAttachment addition (informational)
293 >    function GetSecurityDatabase: AnsiString;
294 >
295 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
296 >   thus now returns accumulated stats for a select statement from opening a cursor
297 >   up to the last fetch.
298 >
299 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
300 >   the problem.
301 >
302 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
303 >   replaces deprecated "comp" type.
304 >
305 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
306 >
307 > 11. URL Connection Strings: inet4 and inet6 now recognised.
308 >
309 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
310 >
311 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
312 >
313 >
314 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
315 >
316 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
317 >
318 > 2. IAttachment: add two new methods
319 >     function HasDefaultCharSet: boolean;
320 >     function GetDefaultCharSetID: integer;
321 >
322 >   These return, respectively, true if a connection default character set was
323 >   specified and the character set id of the connection default character set.
324 >   The DefaultCharSetID is cached when the connection is opened and hence does not
325 >   require a database lookup.
326 >
327 > 3. Avoid exception when a text blob is a stored procedure parameter.
328 >
329 > 4. Update test suite to include a test for a stored proc returning a text blob.
330 >
331 > 5. IAttachment: add
332 >      function GetRemoteProtocol: AnsiString;
333 >      function GetODSMajorVersion: integer;
334 >      function GetODSMinorVersion: integer;
335 >      function GetAuthenticationMethod: AnsiString;
336 >
337 >   These results are cached when the connection is opened and hence do not
338 >   require a database lookup.
339 >
340 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
341 >   connect string used to create/connect to the database.
342 >
343 > 7. IAttachment: Create Database using SQL statement. The username and password
344 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
345 >   It is now possible to use IAttachment disconnect/connect to reconnect to
346 >   a database for which the initial connection was established by a create
347 >   database sql statement. Available in FPC only.
348 >
349 > 8. Update Test 1 to test 5, 6 and 7 above.
350 >
351 > 9. IBUtils code tidy up.
352 >
353 > 10. Parameter Block interfaces "find" method. As documented, this should have
354 >   returned a nil interface when the item could not be found. Instead, an empty
355 >   interface item was returned. "Find" now works as documented and will return
356 >   a nil interface if the item cannot be found.
357 >
358 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
359 >
360 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
361 >    requests with additional parameters. This is to enable support for fb_info_page_contents
362 >    (return of page contents). Response to fb_info_page_contents returned as
363 >    a string with code page CP_NONE.
364 >
365 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
366 >    test suite updated.
367 >
368 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
369 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
370 >
371 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
372 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
373 >    default connection port to be specified.

375 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
376  
377   1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
378     Scale is no longer ignored.
# Line 24 | Line 398 | FBINTF Change Log  version             (
398   6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
399     set supported by Firebird with the API.
400  
401 + 7. Add missing isc_info_db_read_only to list of decoded Database Information items
402 +   in FBOutputBlock.pas and update test suite to include this item.
403 +
404 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
405 +
406 + 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
407 +   library or finding it by disk location, the PATH environment variable is now also set to
408 +   include the FIREBIRD directory. This is to ensure that the correct dlls in the
409 +   firebird client library dependencies are loaded.
410 +
411 + 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
412 +
413 + 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
414 +
415 + 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
416 +
417 + 13. FB30Statement: A check has been added to ensure that all SQL Parameters
418 +    have been given a value (including NULL). Previously, failing to set the
419 +    value of an SQL Parameter could give rise to unpredictable results or
420 +    an SQLDA error.
421 +
422 + 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
