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 +
