1 tony 352 FBINTF Change Log version (1.3-2 Build 12860) Thu, 21 Oct 2021 13:16:09 +0100
2 tony 347
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 Note this can risk out-of-date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 tony 348 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 tony 349 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 tony 350 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33     procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34     also IAttachment:
35     function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36     function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38     aSQLDialect: integer; GenerateParamNames: boolean=false;
39     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40     function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41     GenerateParamNames: boolean=false;
42     CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43 tony 349
44 tony 350 9. Support for scrollable cursors added. New/updated methods:
45     IAttachment:
46 tony 352 function HasScollableCursors: boolean;
47 tony 350 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48     Scrollable: boolean=false): IResultSet; overload;
49     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50     function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51     params: array of const): IResultSet; overload;
52     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53     params: array of const): IResultSet; overload;
54     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55     params: array of const): IResultSet; overload;
56     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57     Scrollable: boolean=false): IResultSet; overload;
58     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60     params: array of const): IResultSet; overload;
61     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63     params: array of const): IResultSet; overload;
64     IStatement:
65     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66     IResultSet:
67     function FetchPrior: boolean; {fetch previous record}
68     function FetchFirst:boolean; {fetch first record}
69     function FetchLast: boolean; {fetch last record}
70     function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71     function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72     function IsBof: boolean;
73    
74    
75    
76 tony 345 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
77    
78     1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
79    
80     2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
81     will now be encoded inline (i.e. as part of the parameter buffer) if they are
82     shorter than a pre-set limit. Longer values continue to be saved as blobs as a
83     separate server interaction. This is intended as a performance optimisation.
84    
85     The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
86     IAttachment interface functions:
87    
88     function GetInlineBlobLimit: integer;
89     procedure SetInlineBlobLimit(limit: integer);
90    
91     3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
92     user as the functionality is embedded in the implementation of the IStatement
93     interface. Three new functions are defined:
94    
95     procedure AddToBatch;
96     function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
97     procedure CancelBatch;
98     function GetBatchCompletion: IBatchCompletion;
99     function GetBatchRowLimit: integer;
100     procedure SetBatchRowLimit(aLimit: integer);
101    
102     Also
103    
104     function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
105     function HasBatchMode: boolean; {true if and only if IBatch Supported}
106    
107     For more information see the User Guide.
108    
109     4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
110     provided with the EIBInterBaseError now include all three parts.
111    
112     5. Firebird.pas and include files updated to Firebird 4.0.0
113    
114     6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
115     Returns SQL Statement type as a text string;
116    
117     7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
118     an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
119    
120 tony 340 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
121 tony 338
122     1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
123     typo in FB30Statement.pas that caused an unknown parameter error.
124    
125 tony 319 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
126 tony 308
127 tony 315 1. Imported (Firebird) constants updated for Firebird 4.
128    
129     2. Firebird.pas from Firebird 4 integrated into source code tree.
130    
131     3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
132    
133     4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
134    
135     5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
136     QueryInterface may be used to coerce this interface from IFirebirdAPI. The
137     interface provides a single method "function GetIMasterIntf: IMaster". This provides
138     type safe access to the Firebird IMaster interface and avoids the need to turn
139     off object checks when coercing "function GetIMaster: TObject" to IMaster.
140    
141     6. New IFirebirdAPI Calls:
142     function HasLocalTZDB: boolean;
143     function HasTimeZoneSupport: boolean;
144     function HasExtendedTZSupport: boolean;
145     procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
146     function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
147    
148     7. New IAttachment Calls:
149     function HasDecFloatSupport: boolean;
150     function GetTimeZoneServices: ITimeZoneServices;
151     function HasTimeZoneSupport: boolean;
152    
153     8. New Interface ITimeZoneServices.
154    
155     9. New ISQLData API Calls:
156     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
157     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
158     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
159     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
160     function GetAsUTCDateTime: TDateTime;
161     function GetAsBCD: tBCD;
162    
163     10. New ISQLParam API Calls
164     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
165     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
166     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
167     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
168     function GetAsUTCDateTime: TDateTime;
169     function GetAsBCD: tBCD;
170     function GetStatement: IStatement;
171     function GetTransaction: ITransaction;
172     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
173     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
174     procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
175     procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
176     procedure SetAsUTCDateTime(aUTCTime: TDateTime);
177     procedure SetAsBcd(aValue: tBCD);
178    
179     11. New IArray API Calls
180     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
181     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
182     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
183     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
184     function GetAsUTCDateTime(index: array of integer): TDateTime;
185     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
186     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
187     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
188     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
189    
190     12. Utility functions in IBUtils
191     function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
192     var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
193     procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
194     function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
195     function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
196     function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
197     function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
198    
199     13. IDPB, ITPB and ISPB: new interface method
200     function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
201     This is used to add a parameter block item by the string equivalent of its
202     symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
203    
204     14. IDPBItem/ITPBItem/ISPBItem: new interface method:
205     function getParamTypeName: AnsiString;
206    
207     15. fb_shutdown now called before unloading Firebird library. This can avoid a
208     SIGEVENT error when a programme using the embeded server is unloaded.
209    
210     FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
211    
212 tony 308 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
213     with a Firebrid 3 client library.
214    
215     2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
216     If a client library path is not explicitly provided and the FIREBIRD environment
217     variable is set then the directory given by this variable and any 'lib' subdirectory
218     are searched for the Firebird client library. Only if none is found, is the default
219     client library used.
220    
221     3. IUtil.FormatStatus now used to format error messages when using new API
222    
223     4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
224    
225     5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
226     returned using GetAsString and the string codepage is UTF8, the string is truncated so
227     that the byte length corresponds to the number of characters specified for the column.
228     SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
229     correct behaviour but may affect some implementations that relied upon automatic
230     trimming of trailing white space.
231    
232     6. New IFirebirdAPI Calls:
233     function GetClientMajor: integer;
234     function GetClientMinor: integer;
235    
236 tony 309 7. IColumnMetaData and IArrayMetaData: new method
237     function GetCharSetWidth: integer;
238 tony 308
239 tony 315 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
240 tony 309
241 tony 287 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
242     case sensitive
243    
244     2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
245    
246 tony 291 3. New API Calls:
247     IColumnMetaData.GetStatement
248     IColumnMetaData.GetTransaction
249 tony 315 ISQLData.GetStrDataLength
250 tony 291 IResults.GetStatement
251     IAttachment.OpenBlob (using Blob metadata)
252     IAttachment.OpenArray (using array metadata)
253    
254     4. FBMessages: removal of unused messages
255    
256     5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
257    
258     6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
259    
260 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
261 tony 265
262     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
263     where the second character of the parameter name is a numeric.
264    
265 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
266     This returns the isc_version connection information as one or more lines.
267     This is the same information as returned by isql with the -z option.
268 tony 265
269 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
270     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
271     compiler option then the Firebird 3 API is no longer compiled in.
272 tony 266
273 tony 270 4. IColumnMetaData: new method.
274    
275     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
276     dfDateTime, {SQL DATETIME}
277     dfTime);
278    
279     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
280    
281     This returns the max. number of characters returned by the "AsString" method
282     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
283    
284     5. Additional argument for IAttachment.PrepareWithNamedParameters -
285     CaseSensitiveParams: boolean = false
286    
287     If this argument is set to true then SQL parameter names are assumed to be case
288     sensitive and must be referenced (using ISQLParams.ByName) using the case
289     sensitive name.
290    
291     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
292     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
293     .AsCurrency) and then subsequently to update the value to a non-numeric string
294     using .AsString.
295    
296    
297    
298 tony 263 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
299 tony 238
300     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
301    
302 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
303     https://bugs.freepascal.org/view.php?id=30535
304    
305     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
306     named parameters and is intended to avoid problems with (e.g.) Execute Block
307     and processing internal parameters as statement parameters.
308    
309     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
310     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
311    
312     5. New function added to IB.pas
313    
314     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
315    
316     This allows a Firebird Library to be loaded from an explicit path. use the
317     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
318     the library. It is possible to load Firebird libraries from different locations
319     simultaneously, each with a distinct IFirebirdAPI.
320    
321 tony 233 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
322 tony 59
323 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
324     program compiled with -CR command line switch.
325    
326     2. IServiceManager additions (informational):
327     function getProtocol: TProtocol;
328     function getPortNo: AnsiString;
329    
330     3. IServiceManager improved error handling. Interfaces changed:
331     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
332     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
333     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
334    
335     4. IAttachment addition (informational)
336     function GetSecurityDatabase: AnsiString;
337    
338     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
339     thus now returns accumulated stats for a select statement from opening a cursor
340     up to the last fetch.
341    
342     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
343     the problem.
344    
345     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
346     replaces deprecated "comp" type.
347    
348 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
349 tony 209
350 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
351 tony 217
352 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
353    
354 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
355 tony 231
356 tony 233
357 tony 209 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
358    
359 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
360    
361 tony 109 2. IAttachment: add two new methods
362     function HasDefaultCharSet: boolean;
363     function GetDefaultCharSetID: integer;
364    
365     These return, respectively, true if a connection default character set was
366 tony 117 specified and the character set id of the connection default character set.
367     The DefaultCharSetID is cached when the connection is opened and hence does not
368     require a database lookup.
369 tony 109
370 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
371 tony 109
372 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
373    
374 tony 117 5. IAttachment: add
375     function GetRemoteProtocol: AnsiString;
376     function GetODSMajorVersion: integer;
377     function GetODSMinorVersion: integer;
378 tony 143 function GetAuthenticationMethod: AnsiString;
379 tony 117
380     These results are cached when the connection is opened and hence do not
381     require a database lookup.
382    
383     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
384     connect string used to create/connect to the database.
385    
386     7. IAttachment: Create Database using SQL statement. The username and password
387     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
388     It is now possible to use IAttachment disconnect/connect to reconnect to
389     a database for which the initial connection was established by a create
390 tony 120 database sql statement. Available in FPC only.
391 tony 117
392     8. Update Test 1 to test 5, 6 and 7 above.
393    
394     9. IBUtils code tidy up.
395    
396 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
397     returned a nil interface when the item could not be found. Instead, an empty
398     interface item was returned. "Find" now works as documented and will return
399     a nil interface if the item cannot be found.
400    
401     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
402    
403     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
404     requests with additional parameters. This is to enable support for fb_info_page_contents
405     (return of page contents). Response to fb_info_page_contents returned as
406     a string with code page CP_NONE.
407    
408     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
409     test suite updated.
410    
411     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
412     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
413    
414     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
415     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
416     default connection port to be specified.

419    
420 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
421     Scale is no longer ignored.
422    
423     2. Fix issues with setting SQL Param values using SetAsString with Date values
424     not in locale format but which are recognised by Firebird. Date values that
425     cannot be converted to a string using Pascal library are now passed through
426     to Firebird as Text Strings.
427    
428 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
429     UTF8 and not UNICODE_FSS.
430    
431     4. Charset ID problem. When using Firebird 3, with no default database character set
432     and a column has a non-default collation specified, an incorrect character set
433     id was being reported that could result in a 'division by zero' error when
434     used by IBX. This has now been fixed.
435    
436     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
437     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
438     the character sets supported can be updated on a per database basis. That is
439     it is possible to add a (Firebird) user defined character set to a database.
440    
441     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
442     set supported by Firebird with the API.
443    
444 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
445     in FBOutputBlock.pas and update test suite to include this item.
446 tony 60
447 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
448 tony 61
449 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
450     library or finding it by disk location, the PATH environment variable is now also set to
451     include the FIREBIRD directory. This is to ensure that the correct dlls in the
452     firebird client library dependencies are loaded.
453 tony 63
454 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
455    
456     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
457    
458     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
459    
460     13. FB30Statement: A check has been added to ensure that all SQL Parameters
461     have been given a value (including NULL). Previously, failing to set the
462     value of an SQL Parameter could give rise to unpredictable results or
463     an SQLDA error.
464    
465     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
466    
467 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
468     parameter in an array of const passed to IAttachment.OpenCursor, etc.
469 tony 68
470 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
471     of const passed to IAttachment.OpenCursor, etc.
472

474 tony 56 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
475 tony 47
476 tony 56 1. Change syntax to Mode Delphi
477    
478     2. Change all uses of string type to explicit AnsiString in order to ensure
479     compatibility between Delphi and FPC.
480    
481     3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
482     defined for each interface.
483    
484     4. Generics syntax variations for Delphi added
485    
486     5. PChar replaced with PByte expect where an actual string is being referenced,
487     where PAnsiChar is used instead.
488    
489     6. Review of type definitions in IBExternals to ensure Delphi compatibility
490    
491     7. Testsuite updated for Delphi
492    
493     FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
494    
495 tony 47 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
496     large blobs and the FB3 API.
497    
498     2. Update Event Handling algorithm to avoid looping due to recreation of the
499     event block.
500    
501     3. Avoid invalid XSQLDA error when the only parameter is updated to null
502    
503     4. Array Handling: fix problem with text arrays with character set none. When the
504     DB connection has a default character set (e.g. UTF8), an error is raised by
505     Firebird if the space allocated is not enough to allow for transliteration, even
506     though it is not required for character set none.
507    
508     5. IBUtils: List of reserved words brought up-to-date
509    
510     6. Add ISQL style performance statistics collection to IStatement
511    
512     7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
513     CREATE DATABASE statement.
514    
515     8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
516     an array dimension is not mistaken for a named parameter prefix.
517    
518     9. Trim function no longer applied to result of GetAsString for SQL_TEXT
519     when Character set is octets. Avoids loss of non printable characters at start of string.
520    
521     10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
522     statistics for the last action. Requires use of procedure IStatement.EnableStatistics
523     to enable stats gathering.
524    
525     11. API Version information added as constants to IB.pas
526    
527     12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
528    
529     13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
