2 tony 363
3     1. Client side journaling support added. Interface changes
4     IAttachment
5     function JournalingActive: boolean;
6     function GetJournalOptions: TJournalOptions;
7     function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
8     function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
9     procedure StopJournaling(RetainJournal: boolean);
10    
11     2. Transactions may now be given a local transaction name:
12     IFirebirdAPI
13     function StartTransaction(Attachments: array of IAttachment;
14     TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
15     TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
16     aName: AnsiString=''): ITransaction; overload;
17     function StartTransaction(Attachments: array of IAttachment;
18     TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
19     TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
20     aName: AnsiString=''): ITransaction; overload;
21    
22     IAttachment
23     function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
24     function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
25     function StartTransaction(TPB: array of byte;
26     DefaultCompletion: TTransactionCompletion=taCommit;
27     aName: AnsiString=''): ITransaction; overload;
28     function StartTransaction(TPB: ITPB;
29     DefaultCompletion: TTransactionCompletion=taCommit;
30     aName: AnsiString=''): ITransaction; overload;
31    
32     ITransaction
33     function GetTransactionName: AnsiString;
34     procedure SetTransactionName(aValue: AnsiString);
35    
36     3. Additional Transaction information
37     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
38    
39     ITransaction
40     function GetDefaultCompletion: TTransactionCompletion;
41     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
42    
43     4. New IAttachment helper functions
44     function HasTable(aTableName: AnsiString): boolean;
45     function GetAttachmentID: integer;
46    
47 tony 359 FBINTF Change Log version (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
48    
49     1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
50    
51     2. Remove constraint in IAttachment.HasScollableCursors that returned false when
52     using remote protocol. Scrollable cursors with remote database expected to
53     be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
54     a not supported error.
55    
56     3. IStatement: new function;
57     TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
58     TStatementFlags = set of TStatementFlag;
59     function GetFlags: TStatementFlags;
60    
61     4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
62     compatibility.
63     In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
64     type changes from ExecProcedure to Select. So that ExecuteQuery can continue
65     to be used with Update...Retruning statements that return a singleton row,
66     instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
67     it will open the cursor and return the first row only.
68    
69     5. ITransaction: new functions:
70     function GetIsReadOnly: boolean;
71     function GetTransactionID: integer;
72     function GetTrInformation(Requests: array of byte): ITrInformation; overload;
73     function GetTrInformation(Request: byte): ITrInformation; overload;
74    
75     The latter two return the Transaction Information block. The first two extract
76     information the Transaction Information block
77    
78     6. New function TSQLTokeniser.ReadCharacters
79     Used internally.
80    
81     7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
82     parameter placeholders instead of named parameters.
83    
84     8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
85     transaction handle is now ignored if Rollback/Commit is called with Force=true
86    
87 tony 356 FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
88 tony 347
89     1. TFBClientAPI.GetProcAddr. Add check for nil reference.
90    
91     2. IStatement: new methods:
92     procedure SetStaleReferenceChecks(Enable:boolean); {default true}
93     function GetStaleReferenceChecks: boolean;
94    
95     In previous versions, stale reference checks were always enabled. This allows the
96     user to disable them on a per statement basis. Note this can risk out-of-date
97     statement BLR. See User Guide.
98    
99 tony 348 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
100     stored procedure and hence avoids replacing named parameters within a containing
101     BEGIN..END block.
102    
103 tony 349 4. ISQLParam: using a string value to set an integer field with a scale factor of
104     zero is now treated as a special case to avoid the risk of floating point
105     rounding errors affecting pure integers.
106    
107     5. ISQLParam: Review and tidy-up of SetAsString for numeric types.
108    
109     6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
110     SQL Parameter metadata (methods moved from ISQLParam).
111    
112     7. ISQLParam: new method
113     function getColMetadata: IParamMetaData;
114     This instance of IParamMetaData returns the original column metadata which is unmutable.
115     Note: ISQLParam metadata can change after a parameter value has been set e.g when
116     setting a VARCHAR column to an integer value.
117    
118 tony 350 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
119     procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
120     also IAttachment:
121     function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
122     function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
123     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
124     aSQLDialect: integer; GenerateParamNames: boolean=false;
125     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
126     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
127     GenerateParamNames: boolean=false;
128     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
129 tony 349
130 tony 350 9. Support for scrollable cursors added. New/updated methods:
131     IAttachment:
132 tony 352 function HasScollableCursors: boolean;
133 tony 350 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
134     Scrollable: boolean=false): IResultSet; overload;
135     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
136     function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
137     params: array of const): IResultSet; overload;
138     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
139     params: array of const): IResultSet; overload;
140     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
141     params: array of const): IResultSet; overload;
142     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
143     Scrollable: boolean=false): IResultSet; overload;
144     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
145     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
146     params: array of const): IResultSet; overload;
147     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
148     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
149     params: array of const): IResultSet; overload;
150     IStatement:
151     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
152     IResultSet:
153     function FetchPrior: boolean; {fetch previous record}
154     function FetchFirst:boolean; {fetch first record}
155     function FetchLast: boolean; {fetch last record}
156     function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
157     function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
158     function IsBof: boolean;
159    
160 tony 353 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
161 tony 350
162 tony 353 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
163     may be noticeable when a line separator occurs inside quoted text. The quoted text
164     output by the tokeniser will now use the platform specific lineEnding regardless
165     of whether the input uses the CRLF or LF as a line separator.
166 tony 350
167 tony 353 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
168    
169    
170 tony 345 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
171    
172     1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
173    
174     2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
175     will now be encoded inline (i.e. as part of the parameter buffer) if they are
176     shorter than a pre-set limit. Longer values continue to be saved as blobs as a
177     separate server interaction. This is intended as a performance optimisation.
178    
179     The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
180     IAttachment interface functions:
181    
182     function GetInlineBlobLimit: integer;
183     procedure SetInlineBlobLimit(limit: integer);
184    
185     3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
186     user as the functionality is embedded in the implementation of the IStatement
187     interface. Three new functions are defined:
188    
189     procedure AddToBatch;
190     function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
191     procedure CancelBatch;
192     function GetBatchCompletion: IBatchCompletion;
193     function GetBatchRowLimit: integer;
194     procedure SetBatchRowLimit(aLimit: integer);
195    
196     Also
197    
198     function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
199     function HasBatchMode: boolean; {true if and only if IBatch Supported}
200    
201     For more information see the User Guide.
202    
203     4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
204     provided with the EIBInterBaseError now include all three parts.
205    
206     5. Firebird.pas and include files updated to Firebird 4.0.0
207    
208     6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
209     Returns SQL Statement type as a text string;
210    
211     7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
212     an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
213    
214 tony 340 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
215 tony 338
216     1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
217     typo in FB30Statement.pas that caused an unknown parameter error.
218    
219 tony 319 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
220 tony 308
221 tony 315 1. Imported (Firebird) constants updated for Firebird 4.
222    
223     2. Firebird.pas from Firebird 4 integrated into source code tree.
224    
225     3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
226    
227     4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
228    
229     5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
230     QueryInterface may be used to coerce this interface from IFirebirdAPI. The
231     interface provides a single method "function GetIMasterIntf: IMaster". This provides
232     type safe access to the Firebird IMaster interface and avoids the need to turn
233     off object checks when coercing "function GetIMaster: TObject" to IMaster.
234    
235     6. New IFirebirdAPI Calls:
236     function HasLocalTZDB: boolean;
237     function HasTimeZoneSupport: boolean;
238     function HasExtendedTZSupport: boolean;
239     procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
240     function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
241    
242     7. New IAttachment Calls:
243     function HasDecFloatSupport: boolean;
244     function GetTimeZoneServices: ITimeZoneServices;
245     function HasTimeZoneSupport: boolean;
246    
247     8. New Interface ITimeZoneServices.
248    
249     9. New ISQLData API Calls:
250     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
251     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
252     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
253     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
254     function GetAsUTCDateTime: TDateTime;
255     function GetAsBCD: tBCD;
256    
257     10. New ISQLParam API Calls
258     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
259     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
260     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
261     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
262     function GetAsUTCDateTime: TDateTime;
263     function GetAsBCD: tBCD;
264     function GetStatement: IStatement;
265     function GetTransaction: ITransaction;
266     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
267     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
268     procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
269     procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
270     procedure SetAsUTCDateTime(aUTCTime: TDateTime);
271     procedure SetAsBcd(aValue: tBCD);
272    
273     11. New IArray API Calls
274     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
275     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
276     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
277     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
278     function GetAsUTCDateTime(index: array of integer): TDateTime;
279     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
280     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
281     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
282     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
283    
284     12. Utility functions in IBUtils
285     function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
286     var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
287     procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
288     function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
289     function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
290     function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
291     function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
292    
293     13. IDPB, ITPB and ISPB: new interface method
294     function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
295     This is used to add a parameter block item by the string equivalent of its
296     symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
297    
298     14. IDPBItem/ITPBItem/ISPBItem: new interface method:
299     function getParamTypeName: AnsiString;
300    
301     15. fb_shutdown now called before unloading Firebird library. This can avoid a
302     SIGEVENT error when a programme using the embeded server is unloaded.
303    
304     FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
305    
306 tony 308 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
307     with a Firebrid 3 client library.
308    
309     2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
310     If a client library path is not explicitly provided and the FIREBIRD environment
311     variable is set then the directory given by this variable and any 'lib' subdirectory
312     are searched for the Firebird client library. Only if none is found, is the default
313     client library used.
314    
315     3. IUtil.FormatStatus now used to format error messages when using new API
316    
317     4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
318    
319     5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
320     returned using GetAsString and the string codepage is UTF8, the string is truncated so
321     that the byte length corresponds to the number of characters specified for the column.
322     SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
323     correct behaviour but may affect some implementations that relied upon automatic
324     trimming of trailing white space.
325    
326     6. New IFirebirdAPI Calls:
327     function GetClientMajor: integer;
328     function GetClientMinor: integer;
329    
330 tony 309 7. IColumnMetaData and IArrayMetaData: new method
331     function GetCharSetWidth: integer;
332 tony 308
333 tony 315 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
334 tony 309
335 tony 287 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
336     case sensitive
337    
338     2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
339    
340 tony 291 3. New API Calls:
341     IColumnMetaData.GetStatement
342     IColumnMetaData.GetTransaction
343 tony 315 ISQLData.GetStrDataLength
344 tony 291 IResults.GetStatement
345     IAttachment.OpenBlob (using Blob metadata)
346     IAttachment.OpenArray (using array metadata)
347    
348     4. FBMessages: removal of unused messages
349    
350     5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
351    
352     6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
353    
354 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
355 tony 265
356     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
357     where the second character of the parameter name is a numeric.
358    
359 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
360     This returns the isc_version connection information as one or more lines.
361     This is the same information as returned by isql with the -z option.
362 tony 265
363 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
364     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
365     compiler option then the Firebird 3 API is no longer compiled in.
366 tony 266
367 tony 270 4. IColumnMetaData: new method.
368    
369     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
370     dfDateTime, {SQL DATETIME}
371     dfTime);
372    
373     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
374    
375     This returns the max. number of characters returned by the "AsString" method
376     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
377    
378     5. Additional argument for IAttachment.PrepareWithNamedParameters -
379     CaseSensitiveParams: boolean = false
380    
381     If this argument is set to true then SQL parameter names are assumed to be case
382     sensitive and must be referenced (using ISQLParams.ByName) using the case
383     sensitive name.
384    
385     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
386     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
387     .AsCurrency) and then subsequently to update the value to a non-numeric string
388     using .AsString.
389

393 tony 238
394     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
395    
396 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
397     https://bugs.freepascal.org/view.php?id=30535
398    
399     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
400     named parameters and is intended to avoid problems with (e.g.) Execute Block
401     and processing internal parameters as statement parameters.
402    
403     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
404     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
405    
406     5. New function added to IB.pas
407    
408     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
409    
410     This allows a Firebird Library to be loaded from an explicit path. use the
411     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
412     the library. It is possible to load Firebird libraries from different locations
413     simultaneously, each with a distinct IFirebirdAPI.

416 tony 59
417 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
418     program compiled with -CR command line switch.
419    
420     2. IServiceManager additions (informational):
421     function getProtocol: TProtocol;
422     function getPortNo: AnsiString;
423    
424     3. IServiceManager improved error handling. Interfaces changed:
425     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
426     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
427     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
428    
429     4. IAttachment addition (informational)
430     function GetSecurityDatabase: AnsiString;
431    
432     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
433     thus now returns accumulated stats for a select statement from opening a cursor
434     up to the last fetch.
435    
436     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
437     the problem.
438    
439     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
440     replaces deprecated "comp" type.
441    
442 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
443 tony 209
444 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
445 tony 217
446 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
447    
448 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
449 tony 231
450 tony 233
451 tony 209 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
452    
453 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
454    
455 tony 109 2. IAttachment: add two new methods
456     function HasDefaultCharSet: boolean;
457     function GetDefaultCharSetID: integer;
458    
459     These return, respectively, true if a connection default character set was
460 tony 117 specified and the character set id of the connection default character set.
461     The DefaultCharSetID is cached when the connection is opened and hence does not
462     require a database lookup.
463 tony 109
464 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
465 tony 109
466 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
467    
468 tony 117 5. IAttachment: add
469     function GetRemoteProtocol: AnsiString;
470     function GetODSMajorVersion: integer;
471     function GetODSMinorVersion: integer;
472 tony 143 function GetAuthenticationMethod: AnsiString;
473 tony 117
474     These results are cached when the connection is opened and hence do not
475     require a database lookup.
476    
477     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
478     connect string used to create/connect to the database.
479    
480     7. IAttachment: Create Database using SQL statement. The username and password
481     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
482     It is now possible to use IAttachment disconnect/connect to reconnect to
483     a database for which the initial connection was established by a create
484 tony 120 database sql statement. Available in FPC only.
485 tony 117
486     8. Update Test 1 to test 5, 6 and 7 above.
487    
488     9. IBUtils code tidy up.
489    
490 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
491     returned a nil interface when the item could not be found. Instead, an empty
492     interface item was returned. "Find" now works as documented and will return
493     a nil interface if the item cannot be found.
494    
495     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
496    
497     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
498     requests with additional parameters. This is to enable support for fb_info_page_contents
499     (return of page contents). Response to fb_info_page_contents returned as
500     a string with code page CP_NONE.
501    
502     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
503     test suite updated.
504    
505     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
506     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
507    
508     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
509     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
510     default connection port to be specified.
511    
512 tony 107 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
513    
514 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
515     Scale is no longer ignored.
516    
517     2. Fix issues with setting SQL Param values using SetAsString with Date values
518     not in locale format but which are recognised by Firebird. Date values that
519     cannot be converted to a string using Pascal library are now passed through
520     to Firebird as Text Strings.
521    
522 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
523     UTF8 and not UNICODE_FSS.
524    
525     4. Charset ID problem. When using Firebird 3, with no default database character set
526     and a column has a non-default collation specified, an incorrect character set
527     id was being reported that could result in a 'division by zero' error when
528     used by IBX. This has now been fixed.
529    
530     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
531     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
532     the character sets supported can be updated on a per database basis. That is
533     it is possible to add a (Firebird) user defined character set to a database.
534    
535     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
536     set supported by Firebird with the API.
537    
538 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
539     in FBOutputBlock.pas and update test suite to include this item.
540 tony 60
541 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
542 tony 61
543 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
544     library or finding it by disk location, the PATH environment variable is now also set to
545     include the FIREBIRD directory. This is to ensure that the correct dlls in the
546     firebird client library dependencies are loaded.
547 tony 63
548 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
549    
550     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
551    
552     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
553    
554     13. FB30Statement: A check has been added to ensure that all SQL Parameters
555     have been given a value (including NULL). Previously, failing to set the
556     value of an SQL Parameter could give rise to unpredictable results or
557     an SQLDA error.
558    
559     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
560    
561 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
562     parameter in an array of const passed to IAttachment.OpenCursor, etc.
563 tony 68
564 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
565     of const passed to IAttachment.OpenCursor, etc.
566    
567    
568 tony 56 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
569 tony 47
570 tony 56 1. Change syntax to Mode Delphi
571    
572     2. Change all uses of string type to explicit AnsiString in order to ensure
573     compatibility between Delphi and FPC.
574    
575     3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
576     defined for each interface.
577    
578     4. Generics syntax variations for Delphi added
579    
580     5. PChar replaced with PByte expect where an actual string is being referenced,
581     where PAnsiChar is used instead.
582    
583     6. Review of type definitions in IBExternals to ensure Delphi compatibility
584    
585     7. Testsuite updated for Delphi
586    
587     FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
588    
589 tony 47 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
590     large blobs and the FB3 API.
591    
592     2. Update Event Handling algorithm to avoid looping due to recreation of the
593     event block.
594    
595     3. Avoid invalid XSQLDA error when the only parameter is updated to null
596    
597     4. Array Handling: fix problem with text arrays with character set none. When the
598     DB connection has a default character set (e.g. UTF8), an error is raised by
599     Firebird if the space allocated is not enough to allow for transliteration, even
600     though it is not required for character set none.
601    
602     5. IBUtils: List of reserved words brought up-to-date
603    
604     6. Add ISQL style performance statistics collection to IStatement
605    
606     7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
607     CREATE DATABASE statement.
608    
609     8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
610     an array dimension is not mistaken for a named parameter prefix.
611    
612     9. Trim function no longer applied to result of GetAsString for SQL_TEXT
613     when Character set is octets. Avoids loss of non printable characters at start of string.
614    
615     10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
616     statistics for the last action. Requires use of procedure IStatement.EnableStatistics
617     to enable stats gathering.
618    
619     11. API Version information added as constants to IB.pas
620    
621     12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
622    
623     13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
624
