1 tony 350 FBINTF Change Log version (1.3-2 Build 12850) Wed, 20 Oct 2021 15:12:15 +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 Note this can risk out-of-date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     IFirebirdAPI:
46     function HasScollableCursors: boolean;
47     IAttachment:
48     function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
49     Scrollable: boolean=false): IResultSet; overload;
50     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
51     function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
52     params: array of const): IResultSet; overload;
53     function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
54     params: array of const): IResultSet; overload;
55     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
56     params: array of const): IResultSet; overload;
57     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
58     Scrollable: boolean=false): IResultSet; overload;
59     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
60     function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
61     params: array of const): IResultSet; overload;
62     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
63     function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
64     params: array of const): IResultSet; overload;
65     IStatement:
66     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
67     IResultSet:
68     function FetchPrior: boolean; {fetch previous record}
69     function FetchFirst:boolean; {fetch first record}
70     function FetchLast: boolean; {fetch last record}
71     function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
72     function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
73     function IsBof: boolean;
74    
75    
76    
77 tony 345 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
78    
79     1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
80    
81     2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
82     will now be encoded inline (i.e. as part of the parameter buffer) if they are
83     shorter than a pre-set limit. Longer values continue to be saved as blobs as a
84     separate server interaction. This is intended as a performance optimisation.
85    
86     The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
87     IAttachment interface functions:
88    
89     function GetInlineBlobLimit: integer;
90     procedure SetInlineBlobLimit(limit: integer);
91    
92     3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
93     user as the functionality is embedded in the implementation of the IStatement
94     interface. Three new functions are defined:
95    
96     procedure AddToBatch;
97     function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
98     procedure CancelBatch;
99     function GetBatchCompletion: IBatchCompletion;
100     function GetBatchRowLimit: integer;
101     procedure SetBatchRowLimit(aLimit: integer);
102    
103     Also
104    
105     function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
106     function HasBatchMode: boolean; {true if and only if IBatch Supported}
107    
108     For more information see the User Guide.
109    
110     4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
111     provided with the EIBInterBaseError now include all three parts.
112    
113     5. Firebird.pas and include files updated to Firebird 4.0.0
114    
115     6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
116     Returns SQL Statement type as a text string;
117    
118     7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
119     an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
120    
121 tony 340 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
122 tony 338
123     1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
124     typo in FB30Statement.pas that caused an unknown parameter error.
125    
126 tony 319 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
127 tony 308
128 tony 315 1. Imported (Firebird) constants updated for Firebird 4.
129    
130     2. Firebird.pas from Firebird 4 integrated into source code tree.
131    
132     3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
133    
134     4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
135    
136     5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
137     QueryInterface may be used to coerce this interface from IFirebirdAPI. The
138     interface provides a single method "function GetIMasterIntf: IMaster". This provides
139     type safe access to the Firebird IMaster interface and avoids the need to turn
140     off object checks when coercing "function GetIMaster: TObject" to IMaster.
141    
142     6. New IFirebirdAPI Calls:
143     function HasLocalTZDB: boolean;
144     function HasTimeZoneSupport: boolean;
145     function HasExtendedTZSupport: boolean;
146     procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
147     function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
148    
149     7. New IAttachment Calls:
150     function HasDecFloatSupport: boolean;
151     function GetTimeZoneServices: ITimeZoneServices;
152     function HasTimeZoneSupport: boolean;
153    
154     8. New Interface ITimeZoneServices.
155    
156     9. New ISQLData API Calls:
157     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
158     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
159     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
160     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
161     function GetAsUTCDateTime: TDateTime;
162     function GetAsBCD: tBCD;
163    
164     10. New ISQLParam API Calls
165     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
166     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
167     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
168     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
169     function GetAsUTCDateTime: TDateTime;
170     function GetAsBCD: tBCD;
171     function GetStatement: IStatement;
172     function GetTransaction: ITransaction;
173     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
174     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
175     procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
176     procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
177     procedure SetAsUTCDateTime(aUTCTime: TDateTime);
178     procedure SetAsBcd(aValue: tBCD);
179    
180     11. New IArray API Calls
181     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
182     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
183     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
184     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
185     function GetAsUTCDateTime(index: array of integer): TDateTime;
186     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
187     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
188     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
189     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
190    
191     12. Utility functions in IBUtils
192     function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
193     var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
194     procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
195     function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
196     function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
197     function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
198     function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
199    
200     13. IDPB, ITPB and ISPB: new interface method
201     function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
202     This is used to add a parameter block item by the string equivalent of its
203     symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
204    
205     14. IDPBItem/ITPBItem/ISPBItem: new interface method:
206     function getParamTypeName: AnsiString;
207    
208     15. fb_shutdown now called before unloading Firebird library. This can avoid a
209     SIGEVENT error when a programme using the embeded server is unloaded.
210    
211     FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
212    
213 tony 308 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
214     with a Firebrid 3 client library.
215    
216     2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
217     If a client library path is not explicitly provided and the FIREBIRD environment
218     variable is set then the directory given by this variable and any 'lib' subdirectory
219     are searched for the Firebird client library. Only if none is found, is the default
220     client library used.
221    
222     3. IUtil.FormatStatus now used to format error messages when using new API
223    
224     4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
225    
226     5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
227     returned using GetAsString and the string codepage is UTF8, the string is truncated so
228     that the byte length corresponds to the number of characters specified for the column.
229     SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
230     correct behaviour but may affect some implementations that relied upon automatic
231     trimming of trailing white space.
232    
233     6. New IFirebirdAPI Calls:
234     function GetClientMajor: integer;
235     function GetClientMinor: integer;
236    
237 tony 309 7. IColumnMetaData and IArrayMetaData: new method
238     function GetCharSetWidth: integer;
239 tony 308
240 tony 315 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
241 tony 309
242 tony 287 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
243     case sensitive
244    
245     2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
246    
247 tony 291 3. New API Calls:
248     IColumnMetaData.GetStatement
249     IColumnMetaData.GetTransaction
250 tony 315 ISQLData.GetStrDataLength
251 tony 291 IResults.GetStatement
252     IAttachment.OpenBlob (using Blob metadata)
253     IAttachment.OpenArray (using array metadata)
254    
255     4. FBMessages: removal of unused messages
256    
257     5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
258    
259     6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
260    
261 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
262 tony 265
263     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
264     where the second character of the parameter name is a numeric.
265    
266 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
267     This returns the isc_version connection information as one or more lines.
268     This is the same information as returned by isql with the -z option.
269 tony 265
270 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
271     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
272     compiler option then the Firebird 3 API is no longer compiled in.
273 tony 266
274 tony 270 4. IColumnMetaData: new method.
275    
276     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
277     dfDateTime, {SQL DATETIME}
278     dfTime);
279    
280     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
281    
282     This returns the max. number of characters returned by the "AsString" method
283     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
284    
285     5. Additional argument for IAttachment.PrepareWithNamedParameters -
286     CaseSensitiveParams: boolean = false
287    
288     If this argument is set to true then SQL parameter names are assumed to be case
289     sensitive and must be referenced (using ISQLParams.ByName) using the case
290     sensitive name.
291    
292     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
293     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
294     .AsCurrency) and then subsequently to update the value to a non-numeric string
295     using .AsString.
296    
297    
298    
299 tony 263 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
300 tony 238
301     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
302    
303 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
304     https://bugs.freepascal.org/view.php?id=30535
305    
306     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
307     named parameters and is intended to avoid problems with (e.g.) Execute Block
308     and processing internal parameters as statement parameters.
309    
310     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
311     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
312    
313     5. New function added to IB.pas
314    
315     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
316    
317     This allows a Firebird Library to be loaded from an explicit path. use the
318     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
319     the library. It is possible to load Firebird libraries from different locations
320     simultaneously, each with a distinct IFirebirdAPI.
321    
322 tony 233 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
323 tony 59
324 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
325     program compiled with -CR command line switch.
326    
327     2. IServiceManager additions (informational):
328     function getProtocol: TProtocol;
329     function getPortNo: AnsiString;
330    
331     3. IServiceManager improved error handling. Interfaces changed:
332     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
333     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
334     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
335    
336     4. IAttachment addition (informational)
337     function GetSecurityDatabase: AnsiString;
338    
339     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
340     thus now returns accumulated stats for a select statement from opening a cursor
341     up to the last fetch.
342    
343     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
344     the problem.
345    
346     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
347     replaces deprecated "comp" type.
348    
349 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
350 tony 209
351 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
352 tony 217
353 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
354    
355 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
356 tony 231
357 tony 233
358 tony 209 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
359    
360 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
361    
362 tony 109 2. IAttachment: add two new methods
363     function HasDefaultCharSet: boolean;
364     function GetDefaultCharSetID: integer;
365    
366     These return, respectively, true if a connection default character set was
367 tony 117 specified and the character set id of the connection default character set.
368     The DefaultCharSetID is cached when the connection is opened and hence does not
369     require a database lookup.
370 tony 109
371 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
372 tony 109
373 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
374    
375 tony 117 5. IAttachment: add
376     function GetRemoteProtocol: AnsiString;
377     function GetODSMajorVersion: integer;
378     function GetODSMinorVersion: integer;
379 tony 143 function GetAuthenticationMethod: AnsiString;
380 tony 117
381     These results are cached when the connection is opened and hence do not
382     require a database lookup.
383    
384     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
385     connect string used to create/connect to the database.
386    
387     7. IAttachment: Create Database using SQL statement. The username and password
388     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
389     It is now possible to use IAttachment disconnect/connect to reconnect to
390     a database for which the initial connection was established by a create
391 tony 120 database sql statement. Available in FPC only.
392 tony 117
393     8. Update Test 1 to test 5, 6 and 7 above.
394    
395     9. IBUtils code tidy up.
396    
397 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
398     returned a nil interface when the item could not be found. Instead, an empty
399     interface item was returned. "Find" now works as documented and will return
400     a nil interface if the item cannot be found.
401    
402     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
403    
404     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
405     requests with additional parameters. This is to enable support for fb_info_page_contents
406     (return of page contents). Response to fb_info_page_contents returned as
407     a string with code page CP_NONE.
408    
409     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
410     test suite updated.
411    
412     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
413     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
414    
415     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
416     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
417     default connection port to be specified.

420    
421 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
422     Scale is no longer ignored.
423    
424     2. Fix issues with setting SQL Param values using SetAsString with Date values
425     not in locale format but which are recognised by Firebird. Date values that
426     cannot be converted to a string using Pascal library are now passed through
427     to Firebird as Text Strings.
428    
429 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
430     UTF8 and not UNICODE_FSS.
431    
432     4. Charset ID problem. When using Firebird 3, with no default database character set
433     and a column has a non-default collation specified, an incorrect character set
434     id was being reported that could result in a 'division by zero' error when
435     used by IBX. This has now been fixed.
436    
437     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
438     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
439     the character sets supported can be updated on a per database basis. That is
440     it is possible to add a (Firebird) user defined character set to a database.
441    
442     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
443     set supported by Firebird with the API.
444    
445 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
446     in FBOutputBlock.pas and update test suite to include this item.
447 tony 60
448 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
449 tony 61
450 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
451     library or finding it by disk location, the PATH environment variable is now also set to
452     include the FIREBIRD directory. This is to ensure that the correct dlls in the
453     firebird client library dependencies are loaded.
454 tony 63
455 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
456    
457     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
458    
459     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
460    
461     13. FB30Statement: A check has been added to ensure that all SQL Parameters
462     have been given a value (including NULL). Previously, failing to set the
463     value of an SQL Parameter could give rise to unpredictable results or
464     an SQLDA error.
465    
466     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
467    
468 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
469     parameter in an array of const passed to IAttachment.OpenCursor, etc.
470 tony 68
471 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
472     of const passed to IAttachment.OpenCursor, etc.
473

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