1 tony 353 FBINTF Change Log version (1.3-2 Build 12878) Sat, 23 Oct 2021 13:23:39 +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 Note this can risk out-of-date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 tony 353 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
75 tony 350
76 tony 353 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
77     may be noticeable when a line separator occurs inside quoted text. The quoted text
78     output by the tokeniser will now use the platform specific lineEnding regardless
79     of whether the input uses the CRLF or LF as a line separator.
80 tony 350
81 tony 353 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
82    
83    
84 tony 345 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
85    
86     1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
87    
88     2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
89     will now be encoded inline (i.e. as part of the parameter buffer) if they are
90     shorter than a pre-set limit. Longer values continue to be saved as blobs as a
91     separate server interaction. This is intended as a performance optimisation.
92    
93     The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
94     IAttachment interface functions:
95    
96     function GetInlineBlobLimit: integer;
97     procedure SetInlineBlobLimit(limit: integer);
98    
99     3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
100     user as the functionality is embedded in the implementation of the IStatement
101     interface. Three new functions are defined:
102    
103     procedure AddToBatch;
104     function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
105     procedure CancelBatch;
106     function GetBatchCompletion: IBatchCompletion;
107     function GetBatchRowLimit: integer;
108     procedure SetBatchRowLimit(aLimit: integer);
109    
110     Also
111    
112     function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
113     function HasBatchMode: boolean; {true if and only if IBatch Supported}
114    
115     For more information see the User Guide.
116    
117     4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
118     provided with the EIBInterBaseError now include all three parts.
119    
120     5. Firebird.pas and include files updated to Firebird 4.0.0
121    
122     6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
123     Returns SQL Statement type as a text string;
124    
125     7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
126     an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
127    
128 tony 340 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
129 tony 338
130     1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
131     typo in FB30Statement.pas that caused an unknown parameter error.
132    
133 tony 319 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
134 tony 308
135 tony 315 1. Imported (Firebird) constants updated for Firebird 4.
136    
137     2. Firebird.pas from Firebird 4 integrated into source code tree.
138    
139     3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
140    
141     4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
142    
143     5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
144     QueryInterface may be used to coerce this interface from IFirebirdAPI. The
145     interface provides a single method "function GetIMasterIntf: IMaster". This provides
146     type safe access to the Firebird IMaster interface and avoids the need to turn
147     off object checks when coercing "function GetIMaster: TObject" to IMaster.
148    
149     6. New IFirebirdAPI Calls:
150     function HasLocalTZDB: boolean;
151     function HasTimeZoneSupport: boolean;
152     function HasExtendedTZSupport: boolean;
153     procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
154     function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
155    
156     7. New IAttachment Calls:
157     function HasDecFloatSupport: boolean;
158     function GetTimeZoneServices: ITimeZoneServices;
159     function HasTimeZoneSupport: boolean;
160    
161     8. New Interface ITimeZoneServices.
162    
163     9. New ISQLData 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    
171     10. New ISQLParam API Calls
172     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
173     procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
174     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
175     procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
176     function GetAsUTCDateTime: TDateTime;
177     function GetAsBCD: tBCD;
178     function GetStatement: IStatement;
179     function GetTransaction: ITransaction;
180     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
181     procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
182     procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
183     procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
184     procedure SetAsUTCDateTime(aUTCTime: TDateTime);
185     procedure SetAsBcd(aValue: tBCD);
186    
187     11. New IArray API Calls
188     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
189     procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
190     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
191     procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
192     function GetAsUTCDateTime(index: array of integer): TDateTime;
193     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
194     procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
195     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
196     procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
197    
198     12. Utility functions in IBUtils
199     function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
200     var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
201     procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
202     function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
203     function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
204     function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
205     function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
206    
207     13. IDPB, ITPB and ISPB: new interface method
208     function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
209     This is used to add a parameter block item by the string equivalent of its
210     symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
211    
212     14. IDPBItem/ITPBItem/ISPBItem: new interface method:
213     function getParamTypeName: AnsiString;
214    
215     15. fb_shutdown now called before unloading Firebird library. This can avoid a
216     SIGEVENT error when a programme using the embeded server is unloaded.
217    
218     FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
219    
220 tony 308 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
221     with a Firebrid 3 client library.
222    
223     2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
224     If a client library path is not explicitly provided and the FIREBIRD environment
225     variable is set then the directory given by this variable and any 'lib' subdirectory
226     are searched for the Firebird client library. Only if none is found, is the default
227     client library used.
228    
229     3. IUtil.FormatStatus now used to format error messages when using new API
230    
231     4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
232    
233     5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
234     returned using GetAsString and the string codepage is UTF8, the string is truncated so
235     that the byte length corresponds to the number of characters specified for the column.
236     SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
237     correct behaviour but may affect some implementations that relied upon automatic
238     trimming of trailing white space.
239    
240     6. New IFirebirdAPI Calls:
241     function GetClientMajor: integer;
242     function GetClientMinor: integer;
243    
244 tony 309 7. IColumnMetaData and IArrayMetaData: new method
245     function GetCharSetWidth: integer;
246 tony 308
247 tony 315 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
248 tony 309
249 tony 287 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
250     case sensitive
251    
252     2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
253    
254 tony 291 3. New API Calls:
255     IColumnMetaData.GetStatement
256     IColumnMetaData.GetTransaction
257 tony 315 ISQLData.GetStrDataLength
258 tony 291 IResults.GetStatement
259     IAttachment.OpenBlob (using Blob metadata)
260     IAttachment.OpenArray (using array metadata)
261    
262     4. FBMessages: removal of unused messages
263    
264     5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
265    
266     6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
267    
268 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
269 tony 265
270     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
271     where the second character of the parameter name is a numeric.
272    
273 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
274     This returns the isc_version connection information as one or more lines.
275     This is the same information as returned by isql with the -z option.
276 tony 265
277 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
278     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
279     compiler option then the Firebird 3 API is no longer compiled in.
280 tony 266
281 tony 270 4. IColumnMetaData: new method.
282    
283     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
284     dfDateTime, {SQL DATETIME}
285     dfTime);
286    
287     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
288    
289     This returns the max. number of characters returned by the "AsString" method
290     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
291    
292     5. Additional argument for IAttachment.PrepareWithNamedParameters -
293     CaseSensitiveParams: boolean = false
294    
295     If this argument is set to true then SQL parameter names are assumed to be case
296     sensitive and must be referenced (using ISQLParams.ByName) using the case
297     sensitive name.
298    
299     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
300     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
301     .AsCurrency) and then subsequently to update the value to a non-numeric string
302     using .AsString.
303    
304    
305    
306 tony 263 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
307 tony 238
308     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
309    
310 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
311     https://bugs.freepascal.org/view.php?id=30535
312    
313     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
314     named parameters and is intended to avoid problems with (e.g.) Execute Block
315     and processing internal parameters as statement parameters.
316    
317     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
318     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
319    
320     5. New function added to IB.pas
321    
322     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
323    
324     This allows a Firebird Library to be loaded from an explicit path. use the
325     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
326     the library. It is possible to load Firebird libraries from different locations
327     simultaneously, each with a distinct IFirebirdAPI.
328    
329 tony 233 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
330 tony 59
331 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
332     program compiled with -CR command line switch.
333    
334     2. IServiceManager additions (informational):
335     function getProtocol: TProtocol;
336     function getPortNo: AnsiString;
337    
338     3. IServiceManager improved error handling. Interfaces changed:
339     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
340     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
341     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
342    
343     4. IAttachment addition (informational)
344     function GetSecurityDatabase: AnsiString;
345    
346     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
347     thus now returns accumulated stats for a select statement from opening a cursor
348     up to the last fetch.
349    
350     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
351     the problem.
352    
353     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
354     replaces deprecated "comp" type.
355    
356 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
357 tony 209
358 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
359 tony 217
360 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
361    
362 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
363 tony 231
364 tony 233
365 tony 209 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
366    
367 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
368    
369 tony 109 2. IAttachment: add two new methods
370     function HasDefaultCharSet: boolean;
371     function GetDefaultCharSetID: integer;
372    
373     These return, respectively, true if a connection default character set was
374 tony 117 specified and the character set id of the connection default character set.
375     The DefaultCharSetID is cached when the connection is opened and hence does not
376     require a database lookup.
377 tony 109
378 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
379 tony 109
380 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
381    
382 tony 117 5. IAttachment: add
383     function GetRemoteProtocol: AnsiString;
384     function GetODSMajorVersion: integer;
385     function GetODSMinorVersion: integer;
386 tony 143 function GetAuthenticationMethod: AnsiString;
387 tony 117
388     These results are cached when the connection is opened and hence do not
389     require a database lookup.
390    
391     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
392     connect string used to create/connect to the database.
393    
394     7. IAttachment: Create Database using SQL statement. The username and password
395     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
396     It is now possible to use IAttachment disconnect/connect to reconnect to
397     a database for which the initial connection was established by a create
398 tony 120 database sql statement. Available in FPC only.
399 tony 117
400     8. Update Test 1 to test 5, 6 and 7 above.
401    
402     9. IBUtils code tidy up.
403    
404 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
405     returned a nil interface when the item could not be found. Instead, an empty
406     interface item was returned. "Find" now works as documented and will return
407     a nil interface if the item cannot be found.
408    
409     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
410    
411     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
412     requests with additional parameters. This is to enable support for fb_info_page_contents
413     (return of page contents). Response to fb_info_page_contents returned as
414     a string with code page CP_NONE.
415    
416     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
417     test suite updated.
418    
419     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
420     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
421    
422     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
423     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
424     default connection port to be specified.

427    
428 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
429     Scale is no longer ignored.
430    
431     2. Fix issues with setting SQL Param values using SetAsString with Date values
432     not in locale format but which are recognised by Firebird. Date values that
433     cannot be converted to a string using Pascal library are now passed through
434     to Firebird as Text Strings.
435    
436 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
437     UTF8 and not UNICODE_FSS.
438    
439     4. Charset ID problem. When using Firebird 3, with no default database character set
440     and a column has a non-default collation specified, an incorrect character set
441     id was being reported that could result in a 'division by zero' error when
442     used by IBX. This has now been fixed.
443    
444     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
445     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
446     the character sets supported can be updated on a per database basis. That is
447     it is possible to add a (Firebird) user defined character set to a database.
448    
449     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
450     set supported by Firebird with the API.
451    
452 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
453     in FBOutputBlock.pas and update test suite to include this item.
454 tony 60
455 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
456 tony 61
457 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
458     library or finding it by disk location, the PATH environment variable is now also set to
459     include the FIREBIRD directory. This is to ensure that the correct dlls in the
460     firebird client library dependencies are loaded.
461 tony 63
462 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
463    
464     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
465    
466     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
467    
468     13. FB30Statement: A check has been added to ensure that all SQL Parameters
469     have been given a value (including NULL). Previously, failing to set the
470     value of an SQL Parameter could give rise to unpredictable results or
471     an SQLDA error.
472    
473     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
474    
475 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
476     parameter in an array of const passed to IAttachment.OpenCursor, etc.
477 tony 68
478 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
479     of const passed to IAttachment.OpenCursor, etc.
480

482 tony 56 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
483 tony 47
484 tony 56 1. Change syntax to Mode Delphi
485    
486     2. Change all uses of string type to explicit AnsiString in order to ensure
487     compatibility between Delphi and FPC.
488    
489     3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
490     defined for each interface.
491    
492     4. Generics syntax variations for Delphi added
493    
494     5. PChar replaced with PByte expect where an actual string is being referenced,
495     where PAnsiChar is used instead.
496    
497     6. Review of type definitions in IBExternals to ensure Delphi compatibility
498    
499     7. Testsuite updated for Delphi
500    
501     FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
502    
503 tony 47 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
504     large blobs and the FB3 API.
505    
506     2. Update Event Handling algorithm to avoid looping due to recreation of the
507     event block.
508    
509     3. Avoid invalid XSQLDA error when the only parameter is updated to null
510    
511     4. Array Handling: fix problem with text arrays with character set none. When the
512     DB connection has a default character set (e.g. UTF8), an error is raised by
513     Firebird if the space allocated is not enough to allow for transliteration, even
514     though it is not required for character set none.
515    
516     5. IBUtils: List of reserved words brought up-to-date
517    
518     6. Add ISQL style performance statistics collection to IStatement
519    
520     7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
521     CREATE DATABASE statement.
522    
523     8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
524     an array dimension is not mistaken for a named parameter prefix.
525    
526     9. Trim function no longer applied to result of GetAsString for SQL_TEXT
527     when Character set is octets. Avoids loss of non printable characters at start of string.
528    
529     10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
530     statistics for the last action. Requires use of procedure IStatement.EnableStatistics
531     to enable stats gathering.
532    
533     11. API Version information added as constants to IB.pas
534    
535     12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
536    
537     13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
