1 + FBINTF Change Log  version          (1.1-4 Build 11339)  Fri, 28 Dec 2018 10:04:19 +0000
2 +
3 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
4 +   where the second character of the parameter name is a numeric.
5 +
6 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
7 +   This returns the isc_version connection information as one or more lines.
8 +   This is the same information as returned by isql with the -z option.
9 +
10 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
11 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
12 +   compiler option then the Firebird 3 API is no longer compiled in.
13 +
14 + 4. IColumnMetaData: new method.
15 +
16 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
17 +                        dfDateTime,   {SQL DATETIME}
18 +                        dfTime);
19 +
20 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
21 +
22 +   This returns the max. number of characters returned by the "AsString" method
23 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
24 +
25 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
26 +     CaseSensitiveParams: boolean = false
27 +
28 +   If this argument is set to true then SQL parameter names are assumed to be case
29 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
30 +   sensitive name.
31 +
32 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
33 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
34 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
35 +   using .AsString.
36 +
37 +
38 +
39 + FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
40 +
41 + 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
42 +
43 + 2. Restrict IsMultiThread check to Unix only for compatibility with
44 +   https://bugs.freepascal.org/view.php?id=30535
45 +
46 + 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
47 +   named parameters and is intended to avoid problems with (e.g.) Execute Block
48 +   and processing internal parameters as statement parameters.
49 +
50 + 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
51 +   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
52 +
53 + 5. New function added to IB.pas
54 +
55 +   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
56 +
57 +   This allows a Firebird Library to be loaded from an explicit path. use the
58 +   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
59 +   the library. It is possible to load Firebird libraries from different locations
60 +   simultaneously, each with a distinct IFirebirdAPI.
61 +
62 + FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
63 +
64 + 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
65 +   program compiled with -CR command line switch.
66 +
67 + 2. IServiceManager additions (informational):
68 +    function getProtocol: TProtocol;
69 +    function getPortNo: AnsiString;
70 +
71 + 3. IServiceManager improved error handling. Interfaces changed:
72 +    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
73 +    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
74 +    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
75 +
76 + 4. IAttachment addition (informational)
77 +    function GetSecurityDatabase: AnsiString;
78 +
79 + 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
80 +   thus now returns accumulated stats for a select statement from opening a cursor
81 +   up to the last fetch.
82 +
83 + 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
84 +   the problem.
85 +
86 + 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
87 +   replaces deprecated "comp" type.
88 +
89 + 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
90 +
91 + 11. URL Connection Strings: inet4 and inet6 now recognised.
92 +
93 + 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
94 +
95 + 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
96 +
97 +
98 + FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
99 +
100 + 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
101 +
102 + 2. IAttachment: add two new methods
103 +     function HasDefaultCharSet: boolean;
104 +     function GetDefaultCharSetID: integer;
105 +
106 +   These return, respectively, true if a connection default character set was
107 +   specified and the character set id of the connection default character set.
108 +   The DefaultCharSetID is cached when the connection is opened and hence does not
109 +   require a database lookup.
110 +
111 + 3. Avoid exception when a text blob is a stored procedure parameter.
112 +
113 + 4. Update test suite to include a test for a stored proc returning a text blob.
114 +
115 + 5. IAttachment: add
116 +      function GetRemoteProtocol: AnsiString;
117 +      function GetODSMajorVersion: integer;
118 +      function GetODSMinorVersion: integer;
119 +      function GetAuthenticationMethod: AnsiString;
120 +
121 +   These results are cached when the connection is opened and hence do not
122 +   require a database lookup.
123 +
124 + 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
125 +   connect string used to create/connect to the database.
126 +
127 + 7. IAttachment: Create Database using SQL statement. The username and password
128 +   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
129 +   It is now possible to use IAttachment disconnect/connect to reconnect to
130 +   a database for which the initial connection was established by a create
131 +   database sql statement. Available in FPC only.
132 +
133 + 8. Update Test 1 to test 5, 6 and 7 above.
134 +
135 + 9. IBUtils code tidy up.
136 +
137 + 10. Parameter Block interfaces "find" method. As documented, this should have
138 +   returned a nil interface when the item could not be found. Instead, an empty
139 +   interface item was returned. "Find" now works as documented and will return
140 +   a nil interface if the item cannot be found.
141 +
142 + 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
143 +
144 + 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
145 +    requests with additional parameters. This is to enable support for fb_info_page_contents
146 +    (return of page contents). Response to fb_info_page_contents returned as
147 +    a string with code page CP_NONE.
148 +
149 + 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
150 +    test suite updated.
151 +
152 + 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
153 +    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
154 +
155 + 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
156 +    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
157 +    default connection port to be specified.
158 +
159 + FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
160 +
161 + 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
162 +   Scale is no longer ignored.
163 +
164 + 2. Fix issues with setting SQL Param values using SetAsString with Date values
165 +   not in locale format but which are recognised by Firebird. Date values that
166 +   cannot be converted to a string using Pascal library are now passed through
167 +   to Firebird as Text Strings.
168 +
169 + 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
170 +   UTF8 and not UNICODE_FSS.
171 +
172 + 4. Charset ID problem. When using Firebird 3, with no default database character set
173 +   and a column has a non-default collation specified, an incorrect character set
174 +   id was being reported that could result in a 'division by zero' error when
175 +   used by IBX. This has now been fixed.
176 +
177 + 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
178 +   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
179 +   the character sets supported can be updated on a per database basis. That is
180 +   it is possible to add a (Firebird) user defined character set to a database.
181 +
182 + 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
183 +   set supported by Firebird with the API.
184 +
185 + 7. Add missing isc_info_db_read_only to list of decoded Database Information items
186 +   in FBOutputBlock.pas and update test suite to include this item.
187 +
188 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
189 +
190 + 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
191 +   library or finding it by disk location, the PATH environment variable is now also set to
192 +   include the FIREBIRD directory. This is to ensure that the correct dlls in the
193 +   firebird client library dependencies are loaded.
194 +
195 + 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
196 +
197 + 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
198 +
199 + 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
200 +
201 + 13. FB30Statement: A check has been added to ensure that all SQL Parameters
202 +    have been given a value (including NULL). Previously, failing to set the
203 +    value of an SQL Parameter could give rise to unpredictable results or
204 +    an SQLDA error.
205 +
206 + 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
207 +
208 + 15. FBAttachment: Avoid string reference count error when processing an Ansistring
209 +    parameter in an array of const passed to IAttachment.OpenCursor, etc.
210 +
211 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
212 +    of const passed to IAttachment.OpenCursor, etc.
213 +
214 +
215 + FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
216 +
217 + 1. Change syntax to Mode Delphi
218 +
219 + 2. Change all uses of string type to explicit AnsiString in order to ensure
220 +   compatibility between Delphi and FPC.
221 +
222 + 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
223 +   defined for each interface.
224 +
225 + 4. Generics syntax variations for Delphi added
226 +
227 + 5. PChar replaced with PByte expect where an actual string is being referenced,
228 +   where PAnsiChar is used instead.
229 +
230 + 6. Review of type definitions in IBExternals to ensure Delphi compatibility
231 +
232 + 7. Testsuite updated for Delphi
233 +
234 + FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
235 +
236 + 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
237 +   large blobs and the FB3 API.
238 +
239 + 2. Update Event Handling algorithm to avoid looping due to recreation of the
240 +   event block.
241 +
242 + 3. Avoid invalid XSQLDA error when the only parameter is updated to null
243 +
244 + 4. Array Handling: fix problem with text arrays with character set none. When the
245 +   DB connection has a default character set (e.g. UTF8), an error is raised by
246 +   Firebird if the space allocated is not enough to allow for transliteration, even
247 +   though it is not required for character set none.
248 +
249 + 5. IBUtils: List of reserved words brought up-to-date
250 +
251 + 6. Add ISQL style performance statistics collection to IStatement
252 +
253 + 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
254 +   CREATE DATABASE statement.
255 +
256 + 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
257 +   an array dimension is not mistaken for a named parameter prefix.
258 +
259 + 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
260 +   when Character set is octets. Avoids loss of non printable characters at start of string.
261 +
262 + 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
263 +    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
264 +    to enable stats gathering.
265 +
266 + 11. API Version information added as constants to IB.pas
267 +
268 + 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
269 +
270 + 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
271 +
