1 < FBINTF Change Log  version                                                    (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12344) Fri, 21 Aug 2020 15:15:24 +0100
2 >
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5 >
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11 >
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13 >
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15 >
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22 >
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26 >
27 > 7.  IColumnMetaData and IArrayMetaData: new method
28 >      function GetCharSetWidth: integer;
29 >
30 >
31 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
32 >
33 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
34 >   case sensitive
35 >
36 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
37 >
38 > 3. New API Calls:
39 >        IColumnMetaData.GetStatement
40 >        IColumnMetaData.GetTransaction
41 >        ISQLData.GetStrLength
42 >        IResults.GetStatement
43 >        IAttachment.OpenBlob (using Blob metadata)
44 >        IAttachment.OpenArray (using array metadata)
45 >
46 > 4. FBMessages: removal of unused messages
47 >
48 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
49 >
50 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
51 >
52 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
53 >
54 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
55 >   where the second character of the parameter name is a numeric.
56 >
57 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
58 >   This returns the isc_version connection information as one or more lines.
59 >   This is the same information as returned by isql with the -z option.
60 >
61 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
62 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
63 >   compiler option then the Firebird 3 API is no longer compiled in.
64 >
65 > 4. IColumnMetaData: new method.
66 >
67 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
68 >                        dfDateTime,   {SQL DATETIME}
69 >                        dfTime);
70 >
71 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
72 >
73 >   This returns the max. number of characters returned by the "AsString" method
74 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
75 >
76 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
77 >     CaseSensitiveParams: boolean = false
78 >
79 >   If this argument is set to true then SQL parameter names are assumed to be case
80 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
81 >   sensitive name.
82 >
83 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
84 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
85 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
86 >   using .AsString.
87 >
88 >
89 >
90 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
91 >
92 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
93 >
94 > 2. Restrict IsMultiThread check to Unix only for compatibility with
95 >   https://bugs.freepascal.org/view.php?id=30535
96 >
97 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
98 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
99 >   and processing internal parameters as statement parameters.
100 >
101 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
102 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
103 >
104 > 5. New function added to IB.pas
105 >
106 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
107 >
108 >   This allows a Firebird Library to be loaded from an explicit path. use the
109 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
110 >   the library. It is possible to load Firebird libraries from different locations
111 >   simultaneously, each with a distinct IFirebirdAPI.
112 >
113 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
114 >
115 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
116 >   program compiled with -CR command line switch.
117 >
118 > 2. IServiceManager additions (informational):
119 >    function getProtocol: TProtocol;
120 >    function getPortNo: AnsiString;
121 >
122 > 3. IServiceManager improved error handling. Interfaces changed:
123 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
124 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
125 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
126 >
127 > 4. IAttachment addition (informational)
128 >    function GetSecurityDatabase: AnsiString;
129 >
130 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
131 >   thus now returns accumulated stats for a select statement from opening a cursor
132 >   up to the last fetch.
133 >
134 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
135 >   the problem.
136 >
137 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
138 >   replaces deprecated "comp" type.
139 >
140 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
141 >
142 > 11. URL Connection Strings: inet4 and inet6 now recognised.
143 >
144 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
145 >
146 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
147 >
148 >
149 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
150 >
151 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
152 >
153 > 2. IAttachment: add two new methods
154 >     function HasDefaultCharSet: boolean;
155 >     function GetDefaultCharSetID: integer;
156 >
157 >   These return, respectively, true if a connection default character set was
158 >   specified and the character set id of the connection default character set.
159 >   The DefaultCharSetID is cached when the connection is opened and hence does not
160 >   require a database lookup.
161 >
162 > 3. Avoid exception when a text blob is a stored procedure parameter.
163 >
164 > 4. Update test suite to include a test for a stored proc returning a text blob.
165 >
166 > 5. IAttachment: add
167 >      function GetRemoteProtocol: AnsiString;
168 >      function GetODSMajorVersion: integer;
169 >      function GetODSMinorVersion: integer;
170 >      function GetAuthenticationMethod: AnsiString;
171 >
172 >   These results are cached when the connection is opened and hence do not
173 >   require a database lookup.
174 >
175 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
176 >   connect string used to create/connect to the database.
177 >
178 > 7. IAttachment: Create Database using SQL statement. The username and password
179 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
180 >   It is now possible to use IAttachment disconnect/connect to reconnect to
181 >   a database for which the initial connection was established by a create
182 >   database sql statement. Available in FPC only.
183 >
184 > 8. Update Test 1 to test 5, 6 and 7 above.
185 >
186 > 9. IBUtils code tidy up.
187 >
188 > 10. Parameter Block interfaces "find" method. As documented, this should have
189 >   returned a nil interface when the item could not be found. Instead, an empty
190 >   interface item was returned. "Find" now works as documented and will return
191 >   a nil interface if the item cannot be found.
192 >
193 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
194 >
195 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
196 >    requests with additional parameters. This is to enable support for fb_info_page_contents
197 >    (return of page contents). Response to fb_info_page_contents returned as
198 >    a string with code page CP_NONE.
199 >
200 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
201 >    test suite updated.
202 >
203 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
204 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
205 >
206 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
207 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
208 >    default connection port to be specified.
209 >
210 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
211 >
212 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
213 >   Scale is no longer ignored.
214 >
215 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
216 >   not in locale format but which are recognised by Firebird. Date values that
217 >   cannot be converted to a string using Pascal library are now passed through
218 >   to Firebird as Text Strings.
219 >
220 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
221 >   UTF8 and not UNICODE_FSS.
222 >
223 > 4. Charset ID problem. When using Firebird 3, with no default database character set
224 >   and a column has a non-default collation specified, an incorrect character set
225 >   id was being reported that could result in a 'division by zero' error when
226 >   used by IBX. This has now been fixed.
227 >
228 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
229 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
230 >   the character sets supported can be updated on a per database basis. That is
231 >   it is possible to add a (Firebird) user defined character set to a database.
232 >
233 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
234 >   set supported by Firebird with the API.
235 >
236 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
237 >   in FBOutputBlock.pas and update test suite to include this item.
238 >
239 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
240 >
241 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
242 >   library or finding it by disk location, the PATH environment variable is now also set to
243 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
244 >   firebird client library dependencies are loaded.
245 >
246 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
247 >
248 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
249 >
250 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
251 >
252 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
253 >    have been given a value (including NULL). Previously, failing to set the
254 >    value of an SQL Parameter could give rise to unpredictable results or
255 >    an SQLDA error.
256 >
257 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
258 >
259 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
260 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
261 >
262 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
263 >    of const passed to IAttachment.OpenCursor, etc.
264 >
265 >
266 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
267 >
268 > 1. Change syntax to Mode Delphi
269 >
270 > 2. Change all uses of string type to explicit AnsiString in order to ensure
271 >   compatibility between Delphi and FPC.
272 >
273 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
274 >   defined for each interface.
275 >
276 > 4. Generics syntax variations for Delphi added
277 >
278 > 5. PChar replaced with PByte expect where an actual string is being referenced,
279 >   where PAnsiChar is used instead.
280 >
281 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
282 >
283 > 7. Testsuite updated for Delphi
284 >
285 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
286  
287   1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
288     large blobs and the FB3 API.
