1 + FBINTF Change Log  version          (1.1-5 Build 12034) Fri, 17 Apr 2020 12:28:42 +0100
2 +
3 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 +   case sensitive
5 +
6 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7 +
8 + 3. New API Calls:
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 +
18 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19 +
20 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21 +
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 +
58 +
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.
259 +
260 + 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 +   event block.
262 +
263 + 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264 +
265 + 4. Array Handling: fix problem with text arrays with character set none. When the
266 +   DB connection has a default character set (e.g. UTF8), an error is raised by
267 +   Firebird if the space allocated is not enough to allow for transliteration, even
268 +   though it is not required for character set none.
269 +
270 + 5. IBUtils: List of reserved words brought up-to-date
271 +
272 + 6. Add ISQL style performance statistics collection to IStatement
273 +
274 + 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 +   CREATE DATABASE statement.
276 +
277 + 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 +   an array dimension is not mistaken for a named parameter prefix.
279 +
280 + 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
281 +   when Character set is octets. Avoids loss of non printable characters at start of string.
282 +
283 + 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
284 +    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 +    to enable stats gathering.
286 +
287 + 11. API Version information added as constants to IB.pas
288 +
289 + 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290 +
291 + 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292 +
