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