1 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
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. TIBExtract: data formatted as Charset set "octets" is now output using
8 <   hexadecimal notation.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
11 <   using a simple XML format.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
17 <   grants to these objects.
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. TIBExtract: Stored Procedures and Views output in dependency order to avoid
24 <   dependency problems restoring complex databases.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
19 7. TIBXScript: This component has been restructured to allow for the processing of
20   embedded XML in INSERT statements and to support interactive sources in addition
21   to non-interactive data sources such as files.
27  
28 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
31 <   SET SQL DIALECT
27 <   SET TERM
28 <   SET AUTODDL
29 <   SET BAIL
30 <   SET ECHO
31 <   SET COUNT
32 <   SET STATS
33 <   SET NAMES <character set>
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 10. IBVersion unit added to hold current IBX Version Number information.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
36 <    and domain definitions.
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 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
41 <    fully supported.
43 > 4. FBMessages: removal of unused messages
44  
45 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
52 < upgrading to IBX2.
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 < 1. Size property of TIBStringField is now the width in characters of the field
55 <   and not the byte length. This applies only to multi-byte character sets such
56 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
55 <   code is not recognised as a bug and hence this change to align the behaviour.
56 <   The TStringField change is expected in fpc 3.2.0.
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 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
59 <   true (default) then Size property value saved in the lfm is ignored. Size is
60 <   always set from the dynamic information read from the database. It is unclear
61 <   why anyone would want to override this and set Size to false.
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 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
64 <   block.
62 > 4. IColumnMetaData: new method.
63  
64 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
65 <   exist when an attempt is made to connect to it (run time only) then an attempt
66 <   is made to create the database.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
71 <   has been successfully created as a result of a call to CreateDatabase or when
72 <   creating a database after it was found not to exist.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 6.  DBControlGrid: a race condition could result in the wrong row image being
71 <    written to the cache. This has been avoided by a trip round the message
76 <    loop before rendering the row image.
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 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
74 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
80 <    known to risk corrupt rendering of row images when the control is first
81 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
82 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
77 <    a TDateEdit control located on an editor panel.
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 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
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  
89 10. DBControlGrid: Removed memory leak when updating rows.
85  
91 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
86  
87 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
96 <   when target codepage is CP_NONE. This is a workaround for
97 <   http://bugs.freepascal.org/view.php?id=30622.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 2. DBLog option removed from TIBStatisticalService - not supported by server
92 <   since Firebird 1.5.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
95 <   similar.
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. IBCodePage: updated mapping between codepages and character id.
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. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
108 <   Firebird. Character sets with a char width of two are not UTF16.
101 > 5. New function added to IB.pas
102  
103 < 6. Strings received from the database are now always transliterated into UTF8
111 <   regardless of the database character set or connection character set. This
112 <   is for compatibility with the LCL.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
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 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
117 <   read in an entire blob just to get the size of the blob. General performance
118 <   improvement when opening datasets containing blobs.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
116 <   is now used.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
120 <   determined.
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 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
128 <   lazarus 1.6.0
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 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
132 <   compilation error.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 1. No character set specified for connection: when a text blob is retrieved, the
139 <  character set is determined by looking up the native character set using then
140 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
141 <  set as the connection.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
144 <   for Login Dialog returing a change to the database path.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
147 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
148 <   entered value to be saved on a project specific basis (design time only).
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
151 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
152 <   Otherwise, it sets the column text to the selected ListField Value.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
154 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
155   column width.
145  
146 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
158 <   and a case insensitive search is requested.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
161 <   or column ListSource.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
151 <   unprepare) when closing and the text has not changed.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
155 <   Less likely to cause a cursor re-use error on Windows.
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 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
170 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 11. TIBTreeView: Guard against nil destination on record changed
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
164 <    string type with the code page set to reflect the returned field encoding after
165 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
166 <    earlier versions.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
170 <    will now result in transliteration to the code page specified for the Firebird driver
181 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
173 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
185 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
186 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
187 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
188 <    the GETACP is used to determine the Windows code page.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
176 <    name used as the lc_ctype when the database was opened. Only valid while the
177 <    Database is connected.
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 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
195 <    id that corresponds to the DefaultCharSetName.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
183 > 9. IBUtils code tidy up.
184  
185 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
186 <   path is given and database attach fails due to access permission issues on the
187 <   temp directory or security database, then the attach is retried with "localhost:"
188 <   prefixing the databasename. This should avoid problems when the database has to
203 <   be accessed by a local (e.g. classic) server and libfbembed is used.
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 < 2. Windows: revised search order for Firebird DLL:
206 <     i.   The Firebird Embedded Server in the application Directory.
207 <     ii.  If the FIREBIRD environment variable is set then the directory this
208 <          points to is searched for the FB Client DLL and then then underlying
209 <          "bin" directory.
210 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
211 <          is used to locate the Firebird installation directory and the underlying
212 <          "bin" directory is searched for the FB Client DLL.
213 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
214 <          are searched for the FB Client DLL.
215 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
216 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
193 <   See doc/readme.scriptengine and example applications.
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 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
198 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
223 <   See dpc/readme.localdatabase and example applications.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 5. IBDynamicGrid: Reordering on column header click should now also work for
201 <   dynamic columns.
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 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
204 <   between incrementing/decrementing the lock count and signalling the event.
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 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 1.3.2 was never formally released and only made available as beta copies.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
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 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
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 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
226 <   i.e. when it is a calculated field
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 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
231 <   This problem was due to a race condition between recalculating row heights and
246 <   determining which row was selected by the mouse click. The row height calculation
247 <   is now deferred by an extra trip round the message loop allowing the row to
248 <   be always calculated on the current grid layout rather than risking it being
249 <   calculated on the grid layout after the expanded row has been shrunk.
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 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
234 <   Windows.
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 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
255 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
256 <   to be determined at runtime. See doc/readme.charactersets.html.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
239 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
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 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
262 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
263 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
266 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
267 <   implies no truncation.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
250 <   (avoids "Not in Edit Mode" error).
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 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
257 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
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 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
281 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
262  
263 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
265 > 1. Change syntax to Mode Delphi
266  
267 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
292 <     problem with row size when exception is called.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
297 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
300 <     keyed in i.e. when autocomplete not performed
280 > 7. Testsuite updated for Delphi
281  
282 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
303 <     console mode applications with all LCL required functions (builtin dialogs and
304 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
305 <     not included in your project, IBX should compile and link with a console mode program.
306 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
307 <     console mode application or the IDE will automatically assume that your
308 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
285 <     to use the built in dialogs and cursor management. IBDialogs is
312 <     included by default if "ibexpress" is in your project source's "uses" clause.
313 <     This should be the case for all projects created through the IDE. This is why
314 <     you do not want to add the ibexpress package to console mode applications. The
315 <     ibexpressconsolemode package has been created to allow console mode programs
316 <     to avoid adding LCL dependencies when using IBX, while still having the
317 <     unit search paths set up correctly.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 <     Existing users should check to ensure that the "ibexpress" unit is included in
288 <     each project's source file (*.lpr).
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
323 <     exists, you have to first open the package in the IDE and then close it. This
324 <     adds it to the most recently accessed packages list. To make it permanently
325 <     available, add the package name to lazarus' staticpackages.inc file.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 <         Thanks to Julio Jiménez for suggesting support of console mode.
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.   SQL Parser can now accept quoted strings that include new lines
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
332 <     of text on start of edit. This is particularly useful when tabbing to a
333 <     column and then inserting text.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 9.   New Examples provided for IB Services and ISQLMonitor.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 10. Fix error when writing to blob streams that recorded only the last buffer
305 <    write in the blob stream. In most cases, this did not cause a problem as the
339 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
340 <    of a graphic type prefix was lost which caused a problem when the image could
341 <        not be automatically recognised.
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 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
308 <    already open" errors due to random numbers used for the cursor name being identical.
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 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
311 <    when opening the table and the Primary Key is the last or only column in the
312 <    table. Thanks to Rick Hoover for the fix.
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 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
351 <    of "UTF-8", and update list of available database character sets. Existing
352 <    users should check the current lc_ctype setting in their applications.
314 > 11. API Version information added as constants to IB.pas
315  
316 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 1.  Firebird Services: avoid List Index error when opening a service with an
357 <    empty Params property.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
360 <    Link now set up in Loaded method - avoids occasional failure to apply
361 <    SQL markup on initial open.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 3.  "Employees" example performance improvements when scrolling.
322 > 1. Initial Release
323  
365 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
366    TFrame. Force recaching of selected frame to avoid GTK race (results in a
367    random image cached).
368
369 5.  DBControlGrid: Should now react to changes in panel height at run time.
370
371 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
372    even when further rows exist.
373
374 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
375    always be derived from panel height and setting this property can cause confusion.
376    Note for existing projects: to avoid a missing property error at run time,
377    each form using the DBControlGrid must be opened, updated and saved in the IDE
378    in order to remove the property value from the lfm.
379
380
381 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
382
383 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
384    call Prepare before setting parameter values.
385
386 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
387
388 3.  Code tidyup and more robust handling of dsql information result vector.
389
390 4.  Support for centralised handling of transaction status changes. TIBTransaction
391    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
392    and "AfterExecQuery". The first three are called after the same event is called
393    for an IBCustomDataSet descendent using the Transaction. The fourth is called
394    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
395    enable monitoring of transaction status changes for a given transaction to be
396    handled in a single place. For example, when a change to the dataset occurs
397    an indicator can be set that shows the user that in order to save changes,
398    the transaction should be committed.  Rather than doing this per dataset, this
399    can now be done per transaction.
400
401 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
402    the dataset is scrolled. However, any changes to the current row are, by default,
403    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
404    have a new property "DataSetCloseAction" that adds automatic posting of changes
405    on dataset close. If this property is set to dcDiscardChanges (default) then the
406    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
407    then IBX will attempt to post any unsaved changes before the dataset is closed
408    (and after the BeforeClose event handler is called). The exception is when the
409    dataset is being closed as a result of a transaction rollback. In this case,
410    no action is taken and any unsaved  changes are discarded. This avoids both
411    unnecessary overhead and the risk that a validation error may occur in the Post
412    raising an exception and thereby preventing a rollback.
413
414 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
415    In earlier versions, the Display Width was set to the maximum byte width rather than the character
416    width. Display Widths are now corrected by dividing by the max byte width per character.
417    For UTF8 character sets, the byte width is four and hence the Display Width will be
418    the byte width divided by 4. The byte width of each character set is determined
419    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
420    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
421
422 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
423
424 8.  IBLookupComboEditBox: List should now always be restored to full list when the
425    control loses focus. Default Key press default interval reduced to 200ms.
426
427 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
428    when dataset rows are less than visible rows.
429
430 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
431    does not exist or DataSet is empty. More responsive on dataset open. New event
432    OnRestorePosition. Column sort disabled if no header row.
433
434 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
435    while dataset state is dsInsert. Avoids posting errors.
436
437 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
438    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
439
440 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
441
442 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
443    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
444    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
445    always "posts" the current record regardless or whether or not it may be more appropriate
446    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
447    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
448    as the first action of the "Post" method and allows the handler to convert the Post
449    into a Cancel if that is the appropriate action on moving to a different row. This is
450    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
451    raised here, but it may still be more appropriate to validate a post and signal
452    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
453
454 15. On Unix derived systems, the Firebird library name can now be given as a colon
455    separated list. Each library name on the list is tried in turn, in left to right
456    order with the first found being used as the firebird library. By default, on Linux,
457    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
458    overidden by the FBLIB environment variable or the OnGetLibraryName function.
459
460    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
461    then it will still attempt to access the database via the Firebird Server and will
462    require a username and password. If only the pathname is given, then the username
463    and password should be omitted and the unix file permissions are used to grant
464    access.
465
466 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
467
468 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
469    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
470    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
471    corresponds to a row of the linked DataSource. Any data aware control on the
472    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
473
474 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
475   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
476   takes place during database access. This may be useful when there are performance issues with
477   the change of cursor. Setting the property to false suppresses the change of cursor.
478
479 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
480   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
481   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
482   making all changes permanent immediately rather than when the transaction is explicitly
483   committed.
484
485 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
486   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

490 Development version only.
491
492 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
493
494 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
495   This is typically used during an "OnBeforeOpen" event handler to manipulate the
496   "Where" and "Having" clauses to implement user specified filters of arbitrary
497   complexity.
498
499 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
500   three new data aware controls dependent on IBX and which make use of the SQL Parser.
501   These are:
502
503   - TIBLookupComboEditBox
504   - TIBDynamicGrid
505   - TIBTreeview
506
507   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
508   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
509   to revise the available list and restrict it to items that are prefixed by the
510   typed text (either case sensitive or case insensitive). Autoinsert allows a
511   newly typed entry to be added to the list dataset and included in the available
512   list items.
513
514   TIBDynamicGrid is a TDBGrid descendent that provides for:
515   - automatic resizing of selected columns to fill the available row length
516   - automatic positioning and sizing of a "totals" control, typically at the
517     column footer, on a per column basis.
518   - DataSet resorting on header row click, sorting the dataset by the selected column.
519     A second click on the same header cell reversed the sort order.
520   - Support for a "Panel Editor". That is on clicking the indicator column, the row
521     is automatically expanded and a panel superimposed on it. The panel can have any
522     number of child controls, typically data aware controls with the same datasource
523     as the grid allowing for editing of additional fields and more complex editors.
524   - Reselection of the same row following resorting.
525   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
526     Its properties are specified on a per column basis and allows for one or more
527     columns to have their values selected from a list provided by a dataset.
528     Autocomplete and autoinsert are also available. The existing picklist editor
529     is unaffected by the extension.
530
531   TIBTreeView is a data aware TCustomTreeView.
532
533 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
534   zero scale will no longer return an error. An Int64 will be returned instead.
535
536 4. TIBTransaction now has events for Before and After Transaction End and a new function
537   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
538
539 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
540   repeated multiple times.
541
542 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
543   check used to get in the way of using Stored Procedures, and "Update or Insert"
544   statements.
545
546 7. Insert, Modify and Delete property Editors now support Query Generation from
547   Stored Procedures.
548
549 8. Three new examples illustrate the use of the new IB Controls
550
551
552 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
553
554 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
555   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
556   Gabor Boros for reporting this problem and for testing the improvements).
557
558 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
559   See readme.field+param.names in the doc folder.
560
561 3. IBX SQL Editors will now automatically add double quotes around column names when the database
562   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
563
564 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
565
566 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
567   actions.
568
569 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
570   thanks to Yuriy Kopnin for pointing this out).
571
572 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
573
574 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
575   for both fields and parameter setting.
576
577 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
578   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
579
580 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
581    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
582
583 11. TIBTable now has a property editor for "MasterFields"
584
585 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
586    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
587
588 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
589    of settings is unrecognised. Selecting this radio button has no effect on the settings.

597
598 1. In a TIBCustomDataset descendent, a generator now only sets the value when
599   it is null. This allows for alternative user defined setting of the generator
600
601   Many thanks to Julio Jiménez for this fix
602
603 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
604   and suggests that the user may have forgotten to install it.

608 1. Conditional compilation used to limit registration of TIntegerField to
609   Lazarus versions less than 1.1
610
611 2. When a database connection is created, character set is now by default set
612   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range

621 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
622
623 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
624   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
625
626 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
627   package is changed to do this (which it should do).
628

630
631 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
632
633 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
634
635 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
636
637 4. Property editors should now correctly resize.
638
639 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
640   (restored original functionality)
641
642 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
643   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
