1 + FBINTF Change Log  version          (1.2-1 Build 12546) Wed, 09 Jun 2021 11:57:29 +0100
2 +
3 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
4 +   typo in FB30Statement.pas that caused an unknown parameter error.
5 +
6 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
7 +
8 + 1. Imported (Firebird) constants updated for Firebird 4.
9 +
10 + 2. Firebird.pas from Firebird 4 integrated into source code tree.
11 +
12 + 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
13 +
14 + 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
15 +
16 + 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
17 +   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
18 +   interface provides a single method "function GetIMasterIntf: IMaster". This provides
19 +   type safe access to the Firebird IMaster interface and avoids the need to turn
20 +   off object checks when coercing "function GetIMaster: TObject" to IMaster.
21 +
22 + 6. New IFirebirdAPI Calls:
23 +    function HasLocalTZDB: boolean;
24 +    function HasTimeZoneSupport: boolean;
25 +    function HasExtendedTZSupport: boolean;
26 +    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
27 +    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
28 +
29 + 7. New IAttachment Calls:
30 +    function HasDecFloatSupport: boolean;
31 +    function GetTimeZoneServices: ITimeZoneServices;
32 +    function HasTimeZoneSupport: boolean;
33 +
34 + 8. New Interface ITimeZoneServices.
35 +
36 + 9. New ISQLData API Calls:
37 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
38 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
39 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
40 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
41 +    function GetAsUTCDateTime: TDateTime;
42 +    function GetAsBCD: tBCD;
43 +
44 + 10. New ISQLParam API Calls
45 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
46 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
47 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
48 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
49 +    function GetAsUTCDateTime: TDateTime;
50 +    function GetAsBCD: tBCD;
51 +    function GetStatement: IStatement;
52 +    function GetTransaction: ITransaction;
53 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
54 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
55 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
56 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
57 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
58 +    procedure SetAsBcd(aValue: tBCD);
59 +
60 + 11. New IArray API Calls
61 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
62 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
63 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
64 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
65 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
66 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
67 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;

69 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
70 +
71 + 12. Utility functions in IBUtils
72 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
73 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
74 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
75 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
76 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
77 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
78 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
79 +
80 + 13. IDPB, ITPB and ISPB: new interface method
81 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
82 +    This is used to add a parameter block item by the string equivalent of its
83 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
84 +
85 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
86 +      function getParamTypeName: AnsiString;
87 +
88 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
89 +     SIGEVENT error when a programme using the embeded server is unloaded.
90 +
91 + FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
92 +
93 + 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
94 +   with a Firebrid 3 client library.
95 +
96 + 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
97 +    If a client library path is not explicitly provided and the FIREBIRD environment
98 +    variable is set then the directory given by this variable and any 'lib' subdirectory
99 +    are searched for the Firebird client library. Only if none is found, is the default
100 +    client library used.
101 +
102 + 3.  IUtil.FormatStatus now used to format error messages when using new API
103 +
104 + 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
105 +
106 + 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
107 +    returned using GetAsString and the string codepage is UTF8, the string is truncated so
108 +    that the byte length corresponds to the number of characters specified for the column.
109 +    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
110 +    correct behaviour but may affect some implementations that relied upon automatic
111 +    trimming of trailing white space.
112 +
113 + 6.  New IFirebirdAPI Calls:
114 +      function GetClientMajor: integer;
115 +      function GetClientMinor: integer;
116 +
117 + 7.  IColumnMetaData and IArrayMetaData: new method
118 +      function GetCharSetWidth: integer;
119 +
120 + FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
121 +
122 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
123 +   case sensitive
124 +
125 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
126 +
127 + 3. New API Calls:
128 +        IColumnMetaData.GetStatement
129 +        IColumnMetaData.GetTransaction
130 +        ISQLData.GetStrDataLength
131 +        IResults.GetStatement
132 +        IAttachment.OpenBlob (using Blob metadata)
133 +        IAttachment.OpenArray (using array metadata)
134 +
135 + 4. FBMessages: removal of unused messages
136 +
137 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
138 +
139 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
140 +
141 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
142 +
143 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
144 +   where the second character of the parameter name is a numeric.
145 +
146 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
147 +   This returns the isc_version connection information as one or more lines.
148 +   This is the same information as returned by isql with the -z option.
149 +
150 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
151 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
152 +   compiler option then the Firebird 3 API is no longer compiled in.
153 +
154 + 4. IColumnMetaData: new method.
155 +
156 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
157 +                        dfDateTime,   {SQL DATETIME}
158 +                        dfTime);
159 +
160 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
161 +
162 +   This returns the max. number of characters returned by the "AsString" method
163 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
164 +
165 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
166 +     CaseSensitiveParams: boolean = false
167 +
168 +   If this argument is set to true then SQL parameter names are assumed to be case
169 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
170 +   sensitive name.
171 +
172 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
173 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
174 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
175 +   using .AsString.
176 +
177 +
178 +
179 + FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
180 +
181 + 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
182 +
183 + 2. Restrict IsMultiThread check to Unix only for compatibility with
184 +   https://bugs.freepascal.org/view.php?id=30535
185 +
186 + 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
187 +   named parameters and is intended to avoid problems with (e.g.) Execute Block
188 +   and processing internal parameters as statement parameters.
189 +
190 + 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
191 +   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
192 +
193 + 5. New function added to IB.pas
194 +
195 +   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
196 +
197 +   This allows a Firebird Library to be loaded from an explicit path. use the
198 +   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
199 +   the library. It is possible to load Firebird libraries from different locations
200 +   simultaneously, each with a distinct IFirebirdAPI.
201 +
202 + FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
203 +
204 + 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
205 +   program compiled with -CR command line switch.
206 +
207 + 2. IServiceManager additions (informational):
208 +    function getProtocol: TProtocol;
209 +    function getPortNo: AnsiString;
210 +
211 + 3. IServiceManager improved error handling. Interfaces changed:
212 +    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
213 +    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
214 +    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
215 +
216 + 4. IAttachment addition (informational)
217 +    function GetSecurityDatabase: AnsiString;
218 +
219 + 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
220 +   thus now returns accumulated stats for a select statement from opening a cursor
221 +   up to the last fetch.
222 +
223 + 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
224 +   the problem.
225 +
226 + 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
227 +   replaces deprecated "comp" type.
228 +
229 + 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
230 +
231 + 11. URL Connection Strings: inet4 and inet6 now recognised.
232 +
233 + 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
234 +
235 + 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
236 +
237 +
238 + FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
239 +
240 + 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
241 +
242 + 2. IAttachment: add two new methods
243 +     function HasDefaultCharSet: boolean;
244 +     function GetDefaultCharSetID: integer;
245 +
246 +   These return, respectively, true if a connection default character set was
247 +   specified and the character set id of the connection default character set.
248 +   The DefaultCharSetID is cached when the connection is opened and hence does not
249 +   require a database lookup.
250 +
251 + 3. Avoid exception when a text blob is a stored procedure parameter.
252 +
253 + 4. Update test suite to include a test for a stored proc returning a text blob.
254 +
255 + 5. IAttachment: add
256 +      function GetRemoteProtocol: AnsiString;
257 +      function GetODSMajorVersion: integer;
258 +      function GetODSMinorVersion: integer;
259 +      function GetAuthenticationMethod: AnsiString;
260 +
261 +   These results are cached when the connection is opened and hence do not
262 +   require a database lookup.
263 +
264 + 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
265 +   connect string used to create/connect to the database.
266 +
267 + 7. IAttachment: Create Database using SQL statement. The username and password
268 +   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
269 +   It is now possible to use IAttachment disconnect/connect to reconnect to
270 +   a database for which the initial connection was established by a create
271 +   database sql statement. Available in FPC only.
272 +
273 + 8. Update Test 1 to test 5, 6 and 7 above.
274 +
275 + 9. IBUtils code tidy up.
276 +
277 + 10. Parameter Block interfaces "find" method. As documented, this should have
278 +   returned a nil interface when the item could not be found. Instead, an empty
279 +   interface item was returned. "Find" now works as documented and will return
280 +   a nil interface if the item cannot be found.
281 +
282 + 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
283 +
284 + 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
285 +    requests with additional parameters. This is to enable support for fb_info_page_contents
286 +    (return of page contents). Response to fb_info_page_contents returned as
287 +    a string with code page CP_NONE.
288 +
289 + 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
290 +    test suite updated.
291 +
292 + 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
293 +    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
294 +
295 + 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
296 +    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
297 +    default connection port to be specified.
298 +
299 + FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
300 +
301 + 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
302 +   Scale is no longer ignored.
303 +
304 + 2. Fix issues with setting SQL Param values using SetAsString with Date values
305 +   not in locale format but which are recognised by Firebird. Date values that
306 +   cannot be converted to a string using Pascal library are now passed through
307 +   to Firebird as Text Strings.
308 +
309 + 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
310 +   UTF8 and not UNICODE_FSS.
311 +
312 + 4. Charset ID problem. When using Firebird 3, with no default database character set
313 +   and a column has a non-default collation specified, an incorrect character set
314 +   id was being reported that could result in a 'division by zero' error when
315 +   used by IBX. This has now been fixed.
316 +
317 + 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
318 +   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
319 +   the character sets supported can be updated on a per database basis. That is
320 +   it is possible to add a (Firebird) user defined character set to a database.
321 +
322 + 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
323 +   set supported by Firebird with the API.
324 +
325 + 7. Add missing isc_info_db_read_only to list of decoded Database Information items
326 +   in FBOutputBlock.pas and update test suite to include this item.
327 +
328 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
329 +
330 + 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
331 +   library or finding it by disk location, the PATH environment variable is now also set to
332 +   include the FIREBIRD directory. This is to ensure that the correct dlls in the
333 +   firebird client library dependencies are loaded.
334 +
335 + 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
336 +
337 + 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
338 +
339 + 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
340 +
341 + 13. FB30Statement: A check has been added to ensure that all SQL Parameters
342 +    have been given a value (including NULL). Previously, failing to set the
343 +    value of an SQL Parameter could give rise to unpredictable results or
344 +    an SQLDA error.
345 +
346 + 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
347 +
348 + 15. FBAttachment: Avoid string reference count error when processing an Ansistring
349 +    parameter in an array of const passed to IAttachment.OpenCursor, etc.
350 +
351 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
352 +    of const passed to IAttachment.OpenCursor, etc.
353 +
354 +
355 + FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
356 +
357 + 1. Change syntax to Mode Delphi
358 +
359 + 2. Change all uses of string type to explicit AnsiString in order to ensure
360 +   compatibility between Delphi and FPC.
361 +
362 + 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
363 +   defined for each interface.
364 +
365 + 4. Generics syntax variations for Delphi added
366 +
367 + 5. PChar replaced with PByte expect where an actual string is being referenced,
368 +   where PAnsiChar is used instead.
369 +
370 + 6. Review of type definitions in IBExternals to ensure Delphi compatibility
371 +
372 + 7. Testsuite updated for Delphi
373 +
374 + FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
375 +
376 + 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
377 +   large blobs and the FB3 API.
378 +
379 + 2. Update Event Handling algorithm to avoid looping due to recreation of the
380 +   event block.
381 +
382 + 3. Avoid invalid XSQLDA error when the only parameter is updated to null
383 +
384 + 4. Array Handling: fix problem with text arrays with character set none. When the
385 +   DB connection has a default character set (e.g. UTF8), an error is raised by
386 +   Firebird if the space allocated is not enough to allow for transliteration, even
387 +   though it is not required for character set none.
388 +
389 + 5. IBUtils: List of reserved words brought up-to-date
390 +
391 + 6. Add ISQL style performance statistics collection to IStatement
392 +
393 + 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
394 +   CREATE DATABASE statement.
395 +
396 + 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
397 +   an array dimension is not mistaken for a named parameter prefix.
398 +
399 + 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
400 +   when Character set is octets. Avoids loss of non printable characters at start of string.
401 +
402 + 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
403 +    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
404 +    to enable stats gathering.
405 +
406 + 11. API Version information added as constants to IB.pas
407 +
408 + 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
409 +
