1 + FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100

3 < IBX Change Log  version                                                     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
7 < upgrading to IBX2.
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 < 1. Size property of TIBStringField is now the width in characters of the field
8 <   and not the byte length. This applies only to multi-byte character sets such
9 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
10 <   code is not recognised as a bug and hence this change to align the behaviour.
11 <   The TStringField change is expected in fpc 3.2.0.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
14 <   true (default) then Size property value saved in the lfm is ignored. Size is
15 <   always set from the dynamic information read from the database. It is unclear
16 <   why anyone would want to override this and set Size to false.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
17 <   block.
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 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
24 <   exist when an attempt is made to connect to it (run time only) then an attempt
25 <   is made to create the database.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
25 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
26   has been successfully created as a result of a call to CreateDatabase or when
27   creating a database after it was found not to exist.
27  
28 < 6.  DBControlGrid: a race condition could result in the wrong row image being
30 <    written to the cache. This has been avoided by a trip round the message
31 <    loop before rendering the row image.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
31 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
35 <    known to risk corrupt rendering of row images when the control is first
36 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
37 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
40 <    a TDateEdit control located on an editor panel.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
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 < 10. DBControlGrid: Removed memory leak when updating rows.
43 > 4. FBMessages: removal of unused messages
44  
45 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
51 <   when target codepage is CP_NONE. This is a workaround for
52 <   http://bugs.freepascal.org/view.php?id=30622.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 2. DBLog option removed from TIBStatisticalService - not supported by server
52 <   since Firebird 1.5.
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 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
55 <   similar.
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 < 4. IBCodePage: updated mapping between codepages and character id.
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 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
63 <   Firebird. Character sets with a char width of two are not UTF16.
62 > 4. IColumnMetaData: new method.
63  
64 < 6. Strings received from the database are now always transliterated into UTF8
65 <   regardless of the database character set or connection character set. This
66 <   is for compatibility with the LCL.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
71 <   read in an entire blob just to get the size of the blob. General performance
73 <   improvement when opening datasets containing blobs.
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 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
77 <   is now used.
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 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
81 <   determined.
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  
83 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
85  
85 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
86   lazarus 1.6.0
86  
87 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
89 <   compilation error.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 1. No character set specified for connection: when a text blob is retrieved, the
92 <  character set is determined by looking up the native character set using then
95 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
96 <  set as the connection.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
95 <   for Login Dialog returing a change to the database path.
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 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
99 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
103 <   entered value to be saved on a project specific basis (design time only).
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 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
106 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
107 <   Otherwise, it sets the column text to the selected ListField Value.
101 > 5. New function added to IB.pas
102  
103 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
110 <   column width.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
106 <   and a case insensitive search is requested.
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 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
116 <   or column ListSource.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
113 <   unprepare) when closing and the text has not changed.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
116 <   Less likely to cause a cursor re-use error on Windows.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
120 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
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 < 11. TIBTreeView: Guard against nil destination on record changed
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
128 <    string type with the code page set to reflect the returned field encoding after
129 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
132 <    earlier versions.
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 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
132 <    will now result in transliteration to the code page specified for the Firebird driver
136 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
135 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
140 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
141 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
142 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
143 <    the GETACP is used to determine the Windows code page.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
146 <    name used as the lc_ctype when the database was opened. Only valid while the
147 <    Database is connected.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
150 <    id that corresponds to the DefaultCharSetName.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
155 <   path is given and database attach fails due to access permission issues on the
156 <   temp directory or security database, then the attach is retried with "localhost:"
157 <   prefixing the databasename. This should avoid problems when the database has to
158 <   be accessed by a local (e.g. classic) server and libfbembed is used.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
160 2. Windows: revised search order for Firebird DLL:
161     i.   The Firebird Embedded Server in the application Directory.
162     ii.  If the FIREBIRD environment variable is set then the directory this
163          points to is searched for the FB Client DLL and then then underlying
164          "bin" directory.
165     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
166          is used to locate the Firebird installation directory and the underlying
167          "bin" directory is searched for the FB Client DLL.
168     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
169          are searched for the FB Client DLL.
170     v.   The PATH Environment variable is used to search for the FB Client DLL.
171     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
145  
146 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
174 <   See doc/readme.scriptengine and example applications.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
177 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
178 <   See dpc/readme.localdatabase and example applications.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 5. IBDynamicGrid: Reordering on column header click should now also work for
151 <   dynamic columns.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
155 <   between incrementing/decrementing the lock count and signalling the event.
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 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 1.3.2 was never formally released and only made available as beta copies.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
176 <   i.e. when it is a calculated field
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 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
200 <   This problem was due to a race condition between recalculating row heights and
201 <   determining which row was selected by the mouse click. The row height calculation
202 <   is now deferred by an extra trip round the message loop allowing the row to
203 <   be always calculated on the current grid layout rather than risking it being
204 <   calculated on the grid layout after the expanded row has been shrunk.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
207 <   Windows.
183 > 9. IBUtils code tidy up.
184  
185 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
186 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
187 <   to be determined at runtime. See doc/readme.charactersets.html.
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 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
214 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
193 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
194 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
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 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
198 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
222 <   implies no truncation.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
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 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
204 <   (avoids "Not in Edit Mode" error).
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 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
210 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
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 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
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 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
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 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
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 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
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 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
247 <     problem with row size when exception is called.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
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 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
252 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
255 <     keyed in i.e. when autocomplete not performed
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
258 <     console mode applications with all LCL required functions (builtin dialogs and
259 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
260 <     not included in your project, IBX should compile and link with a console mode program.
261 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
262 <     console mode application or the IDE will automatically assume that your
263 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
250 <     to use the built in dialogs and cursor management. IBDialogs is
251 <     included by default if "ibexpress" is in your project source's "uses" clause.
252 <     This should be the case for all projects created through the IDE. This is why
269 <     you do not want to add the ibexpress package to console mode applications. The
270 <     ibexpressconsolemode package has been created to allow console mode programs
271 <     to avoid adding LCL dependencies when using IBX, while still having the
272 <     unit search paths set up correctly.
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 <     Existing users should check to ensure that the "ibexpress" unit is included in
275 <     each project's source file (*.lpr).
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
257 <     exists, you have to first open the package in the IDE and then close it. This
279 <     adds it to the most recently accessed packages list. To make it permanently
280 <     available, add the package name to lazarus' staticpackages.inc file.
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 <         Thanks to Julio Jiménez for suggesting support of console mode.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
284 7.   SQL Parser can now accept quoted strings that include new lines
262  
263 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
287 <     of text on start of edit. This is particularly useful when tabbing to a
288 <     column and then inserting text.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 9.   New Examples provided for IB Services and ISQLMonitor.
265 > 1. Change syntax to Mode Delphi
266  
267 < 10. Fix error when writing to blob streams that recorded only the last buffer
268 <    write in the blob stream. In most cases, this did not cause a problem as the
294 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
295 <    of a graphic type prefix was lost which caused a problem when the image could
296 <        not be automatically recognised.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
271 <    already open" errors due to random numbers used for the cursor name being identical.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
302 <    when opening the table and the Primary Key is the last or only column in the
303 <    table. Thanks to Rick Hoover for the fix.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
276 <    of "UTF-8", and update list of available database character sets. Existing
307 <    users should check the current lc_ctype setting in their applications.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 1.  Firebird Services: avoid List Index error when opening a service with an
312 <    empty Params property.
280 > 7. Testsuite updated for Delphi
281  
282 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
315 <    Link now set up in Loaded method - avoids occasional failure to apply
316 <    SQL markup on initial open.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 3.  "Employees" example performance improvements when scrolling.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
288 <    TFrame. Force recaching of selected frame to avoid GTK race (results in a
322 <    random image cached).
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 5.  DBControlGrid: Should now react to changes in panel height at run time.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
293 <    even when further rows exist.
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 < 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
330 <    always be derived from panel height and setting this property can cause confusion.
331 <    Note for existing projects: to avoid a missing property error at run time,
332 <    each form using the DBControlGrid must be opened, updated and saved in the IDE
333 <    in order to remove the property value from the lfm.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 + 6. Add ISQL style performance statistics collection to IStatement
300  
301 < IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
305 <    call Prepare before setting parameter values.
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 < 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
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 < 3.  Code tidyup and more robust handling of dsql information result vector.
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 < 4.  Support for centralised handling of transaction status changes. TIBTransaction
346 <    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
347 <    and "AfterExecQuery". The first three are called after the same event is called
348 <    for an IBCustomDataSet descendent using the Transaction. The fourth is called
349 <    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
350 <    enable monitoring of transaction status changes for a given transaction to be
351 <    handled in a single place. For example, when a change to the dataset occurs
352 <    an indicator can be set that shows the user that in order to save changes,
353 <    the transaction should be committed.  Rather than doing this per dataset, this
354 <    can now be done per transaction.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
357 <    the dataset is scrolled. However, any changes to the current row are, by default,
358 <    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
359 <    have a new property "DataSetCloseAction" that adds automatic posting of changes
360 <    on dataset close. If this property is set to dcDiscardChanges (default) then the
361 <    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
362 <    then IBX will attempt to post any unsaved changes before the dataset is closed
363 <    (and after the BeforeClose event handler is called). The exception is when the
364 <    dataset is being closed as a result of a transaction rollback. In this case,
365 <    no action is taken and any unsaved  changes are discarded. This avoids both
366 <    unnecessary overhead and the risk that a validation error may occur in the Post
367 <    raising an exception and thereby preventing a rollback.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
370 <    In earlier versions, the Display Width was set to the maximum byte width rather than the character
371 <    width. Display Widths are now corrected by dividing by the max byte width per character.
372 <    For UTF8 character sets, the byte width is four and hence the Display Width will be
373 <    the byte width divided by 4. The byte width of each character set is determined
374 <    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
375 <    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 8.  IBLookupComboEditBox: List should now always be restored to full list when the
380 <    control loses focus. Default Key press default interval reduced to 200ms.
322 > 1. Initial Release
323  
382 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
383    when dataset rows are less than visible rows.
384
385 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
386    does not exist or DataSet is empty. More responsive on dataset open. New event
387    OnRestorePosition. Column sort disabled if no header row.
388
389 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
390    while dataset state is dsInsert. Avoids posting errors.
391
392 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
393    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
394
395 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
396
397 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
398    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
399    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
400    always "posts" the current record regardless or whether or not it may be more appropriate
401    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
402    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
403    as the first action of the "Post" method and allows the handler to convert the Post
404    into a Cancel if that is the appropriate action on moving to a different row. This is
405    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
406    raised here, but it may still be more appropriate to validate a post and signal
407    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
408
409 15. On Unix derived systems, the Firebird library name can now be given as a colon
410    separated list. Each library name on the list is tried in turn, in left to right
411    order with the first found being used as the firebird library. By default, on Linux,
412    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
413    overidden by the FBLIB environment variable or the OnGetLibraryName function.
414
415    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
416    then it will still attempt to access the database via the Firebird Server and will
417    require a username and password. If only the pathname is given, then the username
418    and password should be omitted and the unix file permissions are used to grant
419    access.
420
421 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
422
423 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
424    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
425    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
426    corresponds to a row of the linked DataSource. Any data aware control on the
427    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
428
429 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
430   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
431   takes place during database access. This may be useful when there are performance issues with
432   the change of cursor. Setting the property to false suppresses the change of cursor.
433
434 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
435   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
436   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
437   making all changes permanent immediately rather than when the transaction is explicitly
438   committed.
439
440 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
441   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
442
443 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
444
445 Development version only.
446
447 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
448
449 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
450   This is typically used during an "OnBeforeOpen" event handler to manipulate the
451   "Where" and "Having" clauses to implement user specified filters of arbitrary
452   complexity.
453
454 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
455   three new data aware controls dependent on IBX and which make use of the SQL Parser.
456   These are:
457
458   - TIBLookupComboEditBox
459   - TIBDynamicGrid
460   - TIBTreeview
461
462   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
463   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
464   to revise the available list and restrict it to items that are prefixed by the
465   typed text (either case sensitive or case insensitive). Autoinsert allows a
466   newly typed entry to be added to the list dataset and included in the available
467   list items.
468
469   TIBDynamicGrid is a TDBGrid descendent that provides for:
470   - automatic resizing of selected columns to fill the available row length
471   - automatic positioning and sizing of a "totals" control, typically at the
472     column footer, on a per column basis.
473   - DataSet resorting on header row click, sorting the dataset by the selected column.
474     A second click on the same header cell reversed the sort order.
475   - Support for a "Panel Editor". That is on clicking the indicator column, the row
476     is automatically expanded and a panel superimposed on it. The panel can have any
477     number of child controls, typically data aware controls with the same datasource
478     as the grid allowing for editing of additional fields and more complex editors.
479   - Reselection of the same row following resorting.
480   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
481     Its properties are specified on a per column basis and allows for one or more
482     columns to have their values selected from a list provided by a dataset.
483     Autocomplete and autoinsert are also available. The existing picklist editor
484     is unaffected by the extension.
485
486   TIBTreeView is a data aware TCustomTreeView.
487
488 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
489   zero scale will no longer return an error. An Int64 will be returned instead.
490
491 4. TIBTransaction now has events for Before and After Transaction End and a new function
492   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
493
494 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
495   repeated multiple times.
496
497 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
498   check used to get in the way of using Stored Procedures, and "Update or Insert"
499   statements.
500
501 7. Insert, Modify and Delete property Editors now support Query Generation from
502   Stored Procedures.
503
504 8. Three new examples illustrate the use of the new IB Controls
505
506
507 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
508
509 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
510   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
511   Gabor Boros for reporting this problem and for testing the improvements).
512
513 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
514   See readme.field+param.names in the doc folder.
515
516 3. IBX SQL Editors will now automatically add double quotes around column names when the database
517   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
518
519 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
520
521 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
522   actions.
523
524 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
525   thanks to Yuriy Kopnin for pointing this out).
526
527 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
528
529 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
530   for both fields and parameter setting.
531
532 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
533   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
534
535 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
536    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
537
538 11. TIBTable now has a property editor for "MasterFields"
539
540 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
541    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
542
543 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
544    of settings is unrecognised. Selecting this radio button has no effect on the settings.
545

549 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
550
551 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
552
553 1. In a TIBCustomDataset descendent, a generator now only sets the value when
554   it is null. This allows for alternative user defined setting of the generator
555
556   Many thanks to Julio Jiménez for this fix
557
558 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
559   and suggests that the user may have forgotten to install it.
560
561 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
562
563 1. Conditional compilation used to limit registration of TIntegerField to

578 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
579   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
580
581 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
582   package is changed to do this (which it should do).
