1 < IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. Conditional compilation used to limit registration of TIntegerField to
4 <   Lazarus versions less than 1.1
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. When a database connection is created, character set is now by default set
7 <   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
8 <   1250 to 1254.
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 < IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
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  
16 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
27  
28 < 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
19 <   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
31 <   package is changed to do this (which it should do).
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
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 < 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
43 > 4. FBMessages: removal of unused messages
44  
45 < 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 4. Property editors should now correctly resize.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
50 <   (restored original functionality)
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 >
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321 >
322 > 1. Initial Release
323  
37 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
38   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
