9 >        IColumnMetaData.GetStatement
10 >        IColumnMetaData.GetTransaction
11 >        ISQLData.GetStrLength
12 >        IResults.GetStatement
13 >        IAttachment.OpenBlob (using Blob metadata)
14 >        IAttachment.OpenArray (using array metadata)
15 >
16 > 4. FBMessages: removal of unused messages
17 >

22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23 >
24 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 >   where the second character of the parameter name is a numeric.
26 >
27 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 >   This returns the isc_version connection information as one or more lines.
29 >   This is the same information as returned by isql with the -z option.
30 >
31 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 >   compiler option then the Firebird 3 API is no longer compiled in.
34 >
35 > 4. IColumnMetaData: new method.
36 >
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40 >
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42 >
43 >   This returns the max. number of characters returned by the "AsString" method
44 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45 >
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48 >
49 >   If this argument is set to true then SQL parameter names are assumed to be case
50 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
51 >   sensitive name.
52 >
53 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
56 >   using .AsString.
57 >

59 >
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61 >
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63 >
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66 >
67 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
69 >   and processing internal parameters as statement parameters.
70 >
71 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73 >
74 > 5. New function added to IB.pas
75 >
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77 >
78 >   This allows a Firebird Library to be loaded from an explicit path. use the
79 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 >   the library. It is possible to load Firebird libraries from different locations
81 >   simultaneously, each with a distinct IFirebirdAPI.
82 >
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84 >
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87 >
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91 >
92 > 3. IServiceManager improved error handling. Interfaces changed:
93 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96 >
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99 >
100 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 >   thus now returns accumulated stats for a select statement from opening a cursor
102 >   up to the last fetch.
103 >
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106 >
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109 >
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111 >
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113 >
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115 >
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117 >
118 >
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120 >
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122 >
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126 >
127 >   These return, respectively, true if a connection default character set was
128 >   specified and the character set id of the connection default character set.
129 >   The DefaultCharSetID is cached when the connection is opened and hence does not
130 >   require a database lookup.
131 >
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133 >
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135 >
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141 >
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144 >
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147 >
148 > 7. IAttachment: Create Database using SQL statement. The username and password
149 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 >   It is now possible to use IAttachment disconnect/connect to reconnect to
151 >   a database for which the initial connection was established by a create
152 >   database sql statement. Available in FPC only.
153 >
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155 >
156 > 9. IBUtils code tidy up.
157 >
158 > 10. Parameter Block interfaces "find" method. As documented, this should have
159 >   returned a nil interface when the item could not be found. Instead, an empty
160 >   interface item was returned. "Find" now works as documented and will return
161 >   a nil interface if the item cannot be found.
162 >
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164 >
165 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 >    requests with additional parameters. This is to enable support for fb_info_page_contents
167 >    (return of page contents). Response to fb_info_page_contents returned as
168 >    a string with code page CP_NONE.
169 >
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172 >
173 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175 >
176 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 >    default connection port to be specified.
179 >
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181 >
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184 >
185 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 >   not in locale format but which are recognised by Firebird. Date values that
187 >   cannot be converted to a string using Pascal library are now passed through
188 >   to Firebird as Text Strings.
189 >
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192 >
193 > 4. Charset ID problem. When using Firebird 3, with no default database character set
194 >   and a column has a non-default collation specified, an incorrect character set
195 >   id was being reported that could result in a 'division by zero' error when
196 >   used by IBX. This has now been fixed.
197 >
198 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 >   the character sets supported can be updated on a per database basis. That is
201 >   it is possible to add a (Firebird) user defined character set to a database.
202 >
203 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 >   set supported by Firebird with the API.
205 >
206 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 >   in FBOutputBlock.pas and update test suite to include this item.
208 >
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210 >
211 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 >   library or finding it by disk location, the PATH environment variable is now also set to
213 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 >   firebird client library dependencies are loaded.
215 >
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217 >
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219 >
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221 >
222 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 >    have been given a value (including NULL). Previously, failing to set the
224 >    value of an SQL Parameter could give rise to unpredictable results or
225 >    an SQLDA error.
226 >
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228 >
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
231 >
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234 >
235 >
236 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237 >
238 > 1. Change syntax to Mode Delphi
239 >
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.
242 >
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245 >
246 > 4. Generics syntax variations for Delphi added
247 >
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250 >
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252 >
253 > 7. Testsuite updated for Delphi
254 >
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257   1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258     large blobs and the FB3 API.
