1 tony 287 FBINTF Change Log version (1.1-5 Build 11664) Thu, 11 Apr 2019 09:43:40 +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 tony 280 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
9 tony 265
10     1. Fix a problem with the SQL parameter parser that failed to recognise parameters
11     where the second character of the parameter name is a numeric.
12    
13 tony 266 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
14     This returns the isc_version connection information as one or more lines.
15     This is the same information as returned by isql with the -z option.
16 tony 265
17 tony 270 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
18     is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
19     compiler option then the Firebird 3 API is no longer compiled in.
20 tony 266
21 tony 270 4. IColumnMetaData: new method.
22    
23     TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
24     dfDateTime, {SQL DATETIME}
25     dfTime);
26    
27     function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
28    
29     This returns the max. number of characters returned by the "AsString" method
30     when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
31    
32     5. Additional argument for IAttachment.PrepareWithNamedParameters -
33     CaseSensitiveParams: boolean = false
34    
35     If this argument is set to true then SQL parameter names are assumed to be case
36     sensitive and must be referenced (using ISQLParams.ByName) using the case
37     sensitive name.
38    
39     6. Bug fix: when setting a query parameter, it is now possible, when the parameter
40     is of type VarChar or Char to set the parameter to a numeric value (e.g. using
41     .AsCurrency) and then subsequently to update the value to a non-numeric string
42     using .AsString.

46 tony 263 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
47 tony 238
48     1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
49    
50 tony 263 2. Restrict IsMultiThread check to Unix only for compatibility with
51     https://bugs.freepascal.org/view.php?id=30535
52    
53     3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
54     named parameters and is intended to avoid problems with (e.g.) Execute Block
55     and processing internal parameters as statement parameters.
56    
57     4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
58     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
59    
60     5. New function added to IB.pas
61    
62     function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
63    
64     This allows a Firebird Library to be loaded from an explicit path. use the
65     IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
66     the library. It is possible to load Firebird libraries from different locations
67     simultaneously, each with a distinct IFirebirdAPI.
68    
69 tony 233 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
70 tony 59
71 tony 209 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
72     program compiled with -CR command line switch.
73    
74     2. IServiceManager additions (informational):
75     function getProtocol: TProtocol;
76     function getPortNo: AnsiString;
77    
78     3. IServiceManager improved error handling. Interfaces changed:
79     function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
80     function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
81     function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
82    
83     4. IAttachment addition (informational)
84     function GetSecurityDatabase: AnsiString;
85    
86     5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
87     thus now returns accumulated stats for a select statement from opening a cursor
88     up to the last fetch.
89    
90     6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
91     the problem.
92    
93     7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
94     replaces deprecated "comp" type.
95    
96 tony 217 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
97 tony 209
98 tony 231 11. URL Connection Strings: inet4 and inet6 now recognised.
99 tony 217
100 tony 231 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
101    
102 tony 233 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
103 tony 231
104 tony 233
105 tony 209 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
106    
107 tony 107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
108    
109 tony 109 2. IAttachment: add two new methods
110     function HasDefaultCharSet: boolean;
111     function GetDefaultCharSetID: integer;
112    
113     These return, respectively, true if a connection default character set was
114 tony 117 specified and the character set id of the connection default character set.
115     The DefaultCharSetID is cached when the connection is opened and hence does not
116     require a database lookup.
117 tony 109
118 tony 110 3. Avoid exception when a text blob is a stored procedure parameter.
119 tony 109
120 tony 111 4. Update test suite to include a test for a stored proc returning a text blob.
121    
122 tony 117 5. IAttachment: add
123     function GetRemoteProtocol: AnsiString;
124     function GetODSMajorVersion: integer;
125     function GetODSMinorVersion: integer;
126 tony 143 function GetAuthenticationMethod: AnsiString;
127 tony 117
128     These results are cached when the connection is opened and hence do not
129     require a database lookup.
130    
131     6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
132     connect string used to create/connect to the database.
133    
134     7. IAttachment: Create Database using SQL statement. The username and password
135     are now extracted and used to populate a DPB made available via IAttachment.getDPB.
136     It is now possible to use IAttachment disconnect/connect to reconnect to
137     a database for which the initial connection was established by a create
138 tony 120 database sql statement. Available in FPC only.
139 tony 117
140     8. Update Test 1 to test 5, 6 and 7 above.
141    
142     9. IBUtils code tidy up.
143    
144 tony 143 10. Parameter Block interfaces "find" method. As documented, this should have
145     returned a nil interface when the item could not be found. Instead, an empty
146     interface item was returned. "Find" now works as documented and will return
147     a nil interface if the item cannot be found.
148    
149     11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
150    
151     12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
152     requests with additional parameters. This is to enable support for fb_info_page_contents
153     (return of page contents). Response to fb_info_page_contents returned as
154     a string with code page CP_NONE.
155    
156     13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
157     test suite updated.
158    
159     14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
160     a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
161    
162     15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
163     An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
164     default connection port to be specified.
165    
166 tony 107 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
167    
168 tony 59 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
169     Scale is no longer ignored.
170    
171     2. Fix issues with setting SQL Param values using SetAsString with Date values
172     not in locale format but which are recognised by Firebird. Date values that
173     cannot be converted to a string using Pascal library are now passed through
174     to Firebird as Text Strings.
175    
176 tony 60 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
177     UTF8 and not UNICODE_FSS.
178    
179     4. Charset ID problem. When using Firebird 3, with no default database character set
180     and a column has a non-default collation specified, an incorrect character set
181     id was being reported that could result in a 'division by zero' error when
182     used by IBX. This has now been fixed.
183    
184     5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
185     CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
186     the character sets supported can be updated on a per database basis. That is
187     it is possible to add a (Firebird) user defined character set to a database.
188    
189     6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
190     set supported by Firebird with the API.
191    
192 tony 61 7. Add missing isc_info_db_read_only to list of decoded Database Information items
193     in FBOutputBlock.pas and update test suite to include this item.
194 tony 60
195 tony 63 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
196 tony 61
197 tony 68 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
198     library or finding it by disk location, the PATH environment variable is now also set to
199     include the FIREBIRD directory. This is to ensure that the correct dlls in the
200     firebird client library dependencies are loaded.
201 tony 63
202 tony 68 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
203    
204     11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
205    
206     12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
207    
208     13. FB30Statement: A check has been added to ensure that all SQL Parameters
209     have been given a value (including NULL). Previously, failing to set the
210     value of an SQL Parameter could give rise to unpredictable results or
211     an SQLDA error.
212    
213     14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
214    
215 tony 70 15. FBAttachment: Avoid string reference count error when processing an Ansistring
216     parameter in an array of const passed to IAttachment.OpenCursor, etc.
217 tony 68
218 tony 70 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
219     of const passed to IAttachment.OpenCursor, etc.
220

222 tony 56 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
223 tony 47
224 tony 56 1. Change syntax to Mode Delphi
225    
226     2. Change all uses of string type to explicit AnsiString in order to ensure
227     compatibility between Delphi and FPC.
228    
229     3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
230     defined for each interface.
231    
232     4. Generics syntax variations for Delphi added
233    
234     5. PChar replaced with PByte expect where an actual string is being referenced,
235     where PAnsiChar is used instead.
236    
237     6. Review of type definitions in IBExternals to ensure Delphi compatibility
238    
239     7. Testsuite updated for Delphi
240    
241     FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
242    
243 tony 47 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
244     large blobs and the FB3 API.
245    
246     2. Update Event Handling algorithm to avoid looping due to recreation of the
247     event block.
248    
249     3. Avoid invalid XSQLDA error when the only parameter is updated to null
250    
251     4. Array Handling: fix problem with text arrays with character set none. When the
252     DB connection has a default character set (e.g. UTF8), an error is raised by
253     Firebird if the space allocated is not enough to allow for transliteration, even
254     though it is not required for character set none.
255    
256     5. IBUtils: List of reserved words brought up-to-date
257    
258     6. Add ISQL style performance statistics collection to IStatement
259    
260     7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
261     CREATE DATABASE statement.
262    
263     8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
264     an array dimension is not mistaken for a named parameter prefix.
265    
266     9. Trim function no longer applied to result of GetAsString for SQL_TEXT
267     when Character set is octets. Avoids loss of non printable characters at start of string.
268    
269     10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
270     statistics for the last action. Requires use of procedure IStatement.EnableStatistics
271     to enable stats gathering.
272    
273     11. API Version information added as constants to IB.pas
274    
275     12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
276    
277     13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
278
