1 + FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +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 +
28 + FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29 +
30 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 +   case sensitive
32 +
33 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34 +
35 + 3. New API Calls:
36 +        IColumnMetaData.GetStatement
37 +        IColumnMetaData.GetTransaction
38 +        ISQLData.GetStrLength
39 +        IResults.GetStatement
40 +        IAttachment.OpenBlob (using Blob metadata)
41 +        IAttachment.OpenArray (using array metadata)
42 +
43 + 4. FBMessages: removal of unused messages
44 +
45 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46 +
47 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48 +
49 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50 +
51 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52 +   where the second character of the parameter name is a numeric.
53 +
54 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 +   This returns the isc_version connection information as one or more lines.
56 +   This is the same information as returned by isql with the -z option.
57 +
58 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 +   compiler option then the Firebird 3 API is no longer compiled in.
61 +
62 + 4. IColumnMetaData: new method.
63 +
64 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 +                        dfDateTime,   {SQL DATETIME}
66 +                        dfTime);
67 +
68 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69 +
70 +   This returns the max. number of characters returned by the "AsString" method
71 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72 +
73 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 +     CaseSensitiveParams: boolean = false
75 +
76 +   If this argument is set to true then SQL parameter names are assumed to be case
77 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 +   sensitive name.
79 +
80 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 +   using .AsString.
84 +
85 +
86 +
87 + FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88 +
89 + 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90 +
91 + 2. Restrict IsMultiThread check to Unix only for compatibility with
92 +   https://bugs.freepascal.org/view.php?id=30535
93 +
94 + 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 +   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 +   and processing internal parameters as statement parameters.
97 +
98 + 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 +   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100 +
101 + 5. New function added to IB.pas
102 +
103 +   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104 +
105 +   This allows a Firebird Library to be loaded from an explicit path. use the
106 +   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 +   the library. It is possible to load Firebird libraries from different locations
108 +   simultaneously, each with a distinct IFirebirdAPI.
109 +
110 + FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111 +
112 + 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 +   program compiled with -CR command line switch.
114 +
115 + 2. IServiceManager additions (informational):
116 +    function getProtocol: TProtocol;
117 +    function getPortNo: AnsiString;
118 +
119 + 3. IServiceManager improved error handling. Interfaces changed:
120 +    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 +    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 +    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123 +
124 + 4. IAttachment addition (informational)
125 +    function GetSecurityDatabase: AnsiString;
126 +
127 + 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 +   thus now returns accumulated stats for a select statement from opening a cursor
129 +   up to the last fetch.
130 +
131 + 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 +   the problem.
133 +
134 + 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 +   replaces deprecated "comp" type.
136 +
137 + 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138 +
139 + 11. URL Connection Strings: inet4 and inet6 now recognised.
140 +
141 + 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142 +
143 + 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144 +
145 +
146 + FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147 +
148 + 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149 +
150 + 2. IAttachment: add two new methods
151 +     function HasDefaultCharSet: boolean;
152 +     function GetDefaultCharSetID: integer;
153 +
154 +   These return, respectively, true if a connection default character set was
155 +   specified and the character set id of the connection default character set.
156 +   The DefaultCharSetID is cached when the connection is opened and hence does not
157 +   require a database lookup.
158 +
159 + 3. Avoid exception when a text blob is a stored procedure parameter.
160 +
161 + 4. Update test suite to include a test for a stored proc returning a text blob.
162 +
163 + 5. IAttachment: add
164 +      function GetRemoteProtocol: AnsiString;
165 +      function GetODSMajorVersion: integer;
166 +      function GetODSMinorVersion: integer;
167 +      function GetAuthenticationMethod: AnsiString;
168 +
169 +   These results are cached when the connection is opened and hence do not
170 +   require a database lookup.
171 +
172 + 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 +   connect string used to create/connect to the database.
174 +
175 + 7. IAttachment: Create Database using SQL statement. The username and password
176 +   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 +   It is now possible to use IAttachment disconnect/connect to reconnect to
178 +   a database for which the initial connection was established by a create
179 +   database sql statement. Available in FPC only.
180 +
181 + 8. Update Test 1 to test 5, 6 and 7 above.
182 +
183 + 9. IBUtils code tidy up.
184 +
185 + 10. Parameter Block interfaces "find" method. As documented, this should have
186 +   returned a nil interface when the item could not be found. Instead, an empty
187 +   interface item was returned. "Find" now works as documented and will return
188 +   a nil interface if the item cannot be found.
189 +
190 + 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191 +
192 + 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 +    requests with additional parameters. This is to enable support for fb_info_page_contents
194 +    (return of page contents). Response to fb_info_page_contents returned as
195 +    a string with code page CP_NONE.
196 +
197 + 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 +    test suite updated.
199 +
200 + 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 +    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202 +
203 + 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 +    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 +    default connection port to be specified.
206 +
207 + FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208 +
209 + 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 +   Scale is no longer ignored.
211 +
212 + 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 +   not in locale format but which are recognised by Firebird. Date values that
214 +   cannot be converted to a string using Pascal library are now passed through
215 +   to Firebird as Text Strings.
216 +
217 + 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 +   UTF8 and not UNICODE_FSS.
219 +
220 + 4. Charset ID problem. When using Firebird 3, with no default database character set
221 +   and a column has a non-default collation specified, an incorrect character set
222 +   id was being reported that could result in a 'division by zero' error when
223 +   used by IBX. This has now been fixed.
224 +
225 + 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226 +   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227 +   the character sets supported can be updated on a per database basis. That is
228 +   it is possible to add a (Firebird) user defined character set to a database.
229 +
230 + 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 +   set supported by Firebird with the API.
232 +
233 + 7. Add missing isc_info_db_read_only to list of decoded Database Information items
234 +   in FBOutputBlock.pas and update test suite to include this item.
235 +
236 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237 +
238 + 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 +   library or finding it by disk location, the PATH environment variable is now also set to
240 +   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 +   firebird client library dependencies are loaded.
242 +
243 + 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244 +
245 + 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246 +
247 + 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248 +
249 + 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 +    have been given a value (including NULL). Previously, failing to set the
251 +    value of an SQL Parameter could give rise to unpredictable results or
252 +    an SQLDA error.
253 +
254 + 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255 +
256 + 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 +    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258 +
259 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 +    of const passed to IAttachment.OpenCursor, etc.
261 +
262 +
263 + FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264 +
265 + 1. Change syntax to Mode Delphi
266 +
267 + 2. Change all uses of string type to explicit AnsiString in order to ensure
268 +   compatibility between Delphi and FPC.
269 +
270 + 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 +   defined for each interface.
272 +
273 + 4. Generics syntax variations for Delphi added
274 +
275 + 5. PChar replaced with PByte expect where an actual string is being referenced,
276 +   where PAnsiChar is used instead.
277 +
278 + 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279 +
280 + 7. Testsuite updated for Delphi
281 +
282 + FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283 +
284 + 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 +   large blobs and the FB3 API.
286 +
287 + 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 +   event block.
289 +
290 + 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291 +
292 + 4. Array Handling: fix problem with text arrays with character set none. When the
293 +   DB connection has a default character set (e.g. UTF8), an error is raised by
294 +   Firebird if the space allocated is not enough to allow for transliteration, even
295 +   though it is not required for character set none.
296 +
297 + 5. IBUtils: List of reserved words brought up-to-date
298 +
299 + 6. Add ISQL style performance statistics collection to IStatement
300 +
301 + 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 +   CREATE DATABASE statement.
303 +
304 + 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305 +   an array dimension is not mistaken for a named parameter prefix.
306 +
307 + 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308 +   when Character set is octets. Avoids loss of non printable characters at start of string.
309 +
310 + 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 +    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 +    to enable stats gathering.
313 +
314 + 11. API Version information added as constants to IB.pas
315 +
316 + 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317 +
318 + 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319 +
