19  
20 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21  
22 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
24 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 >   where the second character of the parameter name is a numeric.
26  
27 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
28 <   hexadecimal notation.
27 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 >   This returns the isc_version connection information as one or more lines.
29 >   This is the same information as returned by isql with the -z option.
30  
31 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
32 <   using a simple XML format.
31 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 >   compiler option then the Firebird 3 API is no longer compiled in.
34  
35 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
30 <   grants to these objects.
35 > 4. IColumnMetaData: new method.
36  
37 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
38 <   dependency problems restoring complex databases.
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < 7. TIBXScript: This component has been restructured to allow for the processing of
36 <   embedded XML in INSERT statements and to support interactive sources in addition
37 <   to non-interactive data sources such as files.
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
43 >   This returns the max. number of characters returned by the "AsString" method
44 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45  
46 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
47 <   SET SQL DIALECT
43 <   SET TERM
44 <   SET AUTODDL
45 <   SET BAIL
46 <   SET ECHO
47 <   SET COUNT
48 <   SET STATS
49 <   SET NAMES <character set>
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 < 10. IBVersion unit added to hold current IBX Version Number information.
49 >   If this argument is set to true then SQL parameter names are assumed to be case
50 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
51 >   sensitive name.
52  
53 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
54 <    and domain definitions.
53 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
56 >   using .AsString.
57  
56 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
57    fully supported.
58  
59 13. TIBExtract: when a database dump includes data, the generator values are now also set.
59  
60 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
65 < upgrading to IBX2.
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 1. Size property of TIBStringField is now the width in characters of the field
68 <   and not the byte length. This applies only to multi-byte character sets such
69 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
71 <   code is not recognised as a bug and hence this change to align the behaviour.
72 <   The TStringField change is expected in fpc 3.2.0.
67 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
69 >   and processing internal parameters as statement parameters.
70  
71 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
72 <   true (default) then Size property value saved in the lfm is ignored. Size is
76 <   always set from the dynamic information read from the database. It is unclear
77 <   why anyone would want to override this and set Size to false.
71 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73  
74 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
80 <   block.
74 > 5. New function added to IB.pas
75  
76 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
83 <   exist when an attempt is made to connect to it (run time only) then an attempt
84 <   is made to create the database.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
79 <   has been successfully created as a result of a call to CreateDatabase or when
80 <   creating a database after it was found not to exist.
78 >   This allows a Firebird Library to be loaded from an explicit path. use the
79 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 >   the library. It is possible to load Firebird libraries from different locations
81 >   simultaneously, each with a distinct IFirebirdAPI.
82  
83 < 6.  DBControlGrid: a race condition could result in the wrong row image being
91 <    written to the cache. This has been avoided by a trip round the message
92 <    loop before rendering the row image.
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
86 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
96 <    known to risk corrupt rendering of row images when the control is first
97 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
98 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
89 <    a TDateEdit control located on an editor panel.
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
92 > 3. IServiceManager improved error handling. Interfaces changed:
93 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96  
97 < 10. DBControlGrid: Removed memory leak when updating rows.
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
100 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 >   thus now returns accumulated stats for a select statement from opening a cursor
102 >   up to the last fetch.
103  
104 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
108 <   when target codepage is CP_NONE. This is a workaround for
113 <   http://bugs.freepascal.org/view.php?id=30622.
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109  
110 < 2. DBLog option removed from TIBStatisticalService - not supported by server
116 <   since Firebird 1.5.
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
119 <   similar.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 4. IBCodePage: updated mapping between codepages and character id.
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
124 <   Firebird. Character sets with a char width of two are not UTF16.
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
126 6. Strings received from the database are now always transliterated into UTF8
127   regardless of the database character set or connection character set. This
128   is for compatibility with the LCL.
118  
119 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
133 <   read in an entire blob just to get the size of the blob. General performance
134 <   improvement when opening datasets containing blobs.
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
128 <   is now used.
127 >   These return, respectively, true if a connection default character set was
128 >   specified and the character set id of the connection default character set.
129 >   The DefaultCharSetID is cached when the connection is opened and hence does not
130 >   require a database lookup.
131  
132 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
142 <   determined.
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
137 <   lazarus 1.6.0
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
143 <   compilation error.
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144  
145 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 < 1. No character set specified for connection: when a text blob is retrieved, the
149 <  character set is determined by looking up the native character set using then
150 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
151 <  set as the connection.
148 > 7. IAttachment: Create Database using SQL statement. The username and password
149 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 >   It is now possible to use IAttachment disconnect/connect to reconnect to
151 >   a database for which the initial connection was established by a create
152 >   database sql statement. Available in FPC only.
153  
154 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
160 <   for Login Dialog returing a change to the database path.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
163 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
164 <   entered value to be saved on a project specific basis (design time only).
156 > 9. IBUtils code tidy up.
157  
158 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
159 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
160 <   Otherwise, it sets the column text to the selected ListField Value.
158 > 10. Parameter Block interfaces "find" method. As documented, this should have
159 >   returned a nil interface when the item could not be found. Instead, an empty
160 >   interface item was returned. "Find" now works as documented and will return
161 >   a nil interface if the item cannot be found.
162  
163 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
171 <   column width.
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
166 <   and a case insensitive search is requested.
165 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 >    requests with additional parameters. This is to enable support for fb_info_page_contents
167 >    (return of page contents). Response to fb_info_page_contents returned as
168 >    a string with code page CP_NONE.
169  
170 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
171 <   or column ListSource.
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
174 <   unprepare) when closing and the text has not changed.
173 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175  
176 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
177 <   Less likely to cause a cursor re-use error on Windows.
176 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 >    default connection port to be specified.
179  
180 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
186 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 11. TIBTreeView: Guard against nil destination on record changed
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
186 <    string type with the code page set to reflect the returned field encoding after
187 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
188 <    earlier versions.
185 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 >   not in locale format but which are recognised by Firebird. Date values that
187 >   cannot be converted to a string using Pascal library are now passed through
188 >   to Firebird as Text Strings.
189  
190 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
191 <    will now result in transliteration to the code page specified for the Firebird driver
197 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
194 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
195 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
196 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
203 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
204 <    the GETACP is used to determine the Windows code page.
193 > 4. Charset ID problem. When using Firebird 3, with no default database character set
194 >   and a column has a non-default collation specified, an incorrect character set
195 >   id was being reported that could result in a 'division by zero' error when
196 >   used by IBX. This has now been fixed.
197  
198 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
199 <    name used as the lc_ctype when the database was opened. Only valid while the
200 <    Database is connected.
198 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 >   the character sets supported can be updated on a per database basis. That is
201 >   it is possible to add a (Firebird) user defined character set to a database.
202  
203 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
204 <    id that corresponds to the DefaultCharSetName.
203 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 >   set supported by Firebird with the API.
205  
206 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
206 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 >   in FBOutputBlock.pas and update test suite to include this item.
208  
209 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
216 <   path is given and database attach fails due to access permission issues on the
217 <   temp directory or security database, then the attach is retried with "localhost:"
218 <   prefixing the databasename. This should avoid problems when the database has to
219 <   be accessed by a local (e.g. classic) server and libfbembed is used.
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < 2. Windows: revised search order for Firebird DLL:
212 <     i.   The Firebird Embedded Server in the application Directory.
213 <     ii.  If the FIREBIRD environment variable is set then the directory this
214 <          points to is searched for the FB Client DLL and then then underlying
225 <          "bin" directory.
226 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
227 <          is used to locate the Firebird installation directory and the underlying
228 <          "bin" directory is searched for the FB Client DLL.
229 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
230 <          are searched for the FB Client DLL.
231 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
232 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
211 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 >   library or finding it by disk location, the PATH environment variable is now also set to
213 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 >   firebird client library dependencies are loaded.
215  
216 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
235 <   See doc/readme.scriptengine and example applications.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
238 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
239 <   See dpc/readme.localdatabase and example applications.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219  
220 < 5. IBDynamicGrid: Reordering on column header click should now also work for
242 <   dynamic columns.
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
223 <   between incrementing/decrementing the lock count and signalling the event.
222 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 >    have been given a value (including NULL). Previously, failing to set the
224 >    value of an SQL Parameter could give rise to unpredictable results or
225 >    an SQLDA error.
226  
227 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < 1.3.2 was never formally released and only made available as beta copies.
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
231  
232 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234  
253 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
235  
236 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
236 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237  
238 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
258 <   i.e. when it is a calculated field
238 > 1. Change syntax to Mode Delphi
239  
240 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
241 <   This problem was due to a race condition between recalculating row heights and
262 <   determining which row was selected by the mouse click. The row height calculation
263 <   is now deferred by an extra trip round the message loop allowing the row to
264 <   be always calculated on the current grid layout rather than risking it being
265 <   calculated on the grid layout after the expanded row has been shrunk.
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.
242  
243 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
244 <   Windows.
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
271 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
272 <   to be determined at runtime. See doc/readme.charactersets.html.
246 > 4. Generics syntax variations for Delphi added
247  
248 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
249 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
278 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
279 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
282 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
283 <   implies no truncation.
253 > 7. Testsuite updated for Delphi
254  
255 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
258 <   (avoids "Not in Edit Mode" error).
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
293 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
265 > 4. Array Handling: fix problem with text arrays with character set none. When the
266 >   DB connection has a default character set (e.g. UTF8), an error is raised by
267 >   Firebird if the space allocated is not enough to allow for transliteration, even
268 >   though it is not required for character set none.
269  
270 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
272 > 6. Add ISQL style performance statistics collection to IStatement
273  
274 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
277 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 >   an array dimension is not mistaken for a named parameter prefix.
279  
280 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
280 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
281 >   when Character set is octets. Avoids loss of non printable characters at start of string.
282  
283 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
284 <     problem with row size when exception is called.
283 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
284 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 >    to enable stats gathering.
286  
287 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
287 > 11. API Version information added as constants to IB.pas
288  
289 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
313 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
289 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290  
291 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
316 <     keyed in i.e. when autocomplete not performed
291 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292  
293 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
319 <     console mode applications with all LCL required functions (builtin dialogs and
320 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
321 <     not included in your project, IBX should compile and link with a console mode program.
322 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
323 <     console mode application or the IDE will automatically assume that your
324 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
293 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
294  
295 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
327 <     to use the built in dialogs and cursor management. IBDialogs is
328 <     included by default if "ibexpress" is in your project source's "uses" clause.
329 <     This should be the case for all projects created through the IDE. This is why
330 <     you do not want to add the ibexpress package to console mode applications. The
331 <     ibexpressconsolemode package has been created to allow console mode programs
332 <     to avoid adding LCL dependencies when using IBX, while still having the
333 <     unit search paths set up correctly.
295 > 1. Initial Release
296  
335     Existing users should check to ensure that the "ibexpress" unit is included in
336     each project's source file (*.lpr).
337
338     You may find that in order for the IDE to recognise that ibexpressconsolemode
339     exists, you have to first open the package in the IDE and then close it. This
340     adds it to the most recently accessed packages list. To make it permanently
341     available, add the package name to lazarus' staticpackages.inc file.
342
343         Thanks to Julio Jiménez for suggesting support of console mode.
344
345 7.   SQL Parser can now accept quoted strings that include new lines
346
347 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
348     of text on start of edit. This is particularly useful when tabbing to a
349     column and then inserting text.
350
351 9.   New Examples provided for IB Services and ISQLMonitor.
352
353 10. Fix error when writing to blob streams that recorded only the last buffer
354    write in the blob stream. In most cases, this did not cause a problem as the
355    IB Blob Stream is written in a single write. However, with the TDBImage, write
356    of a graphic type prefix was lost which caused a problem when the image could
357        not be automatically recognised.
358
359 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
360    already open" errors due to random numbers used for the cursor name being identical.
361
362 12. IBTable: corrected error that could result in an "Index out of bounds" error
363    when opening the table and the Primary Key is the last or only column in the
364    table. Thanks to Rick Hoover for the fix.
365
366 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
367    of "UTF-8", and update list of available database character sets. Existing
368    users should check the current lc_ctype setting in their applications.
369
370 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
371
372 1.  Firebird Services: avoid List Index error when opening a service with an
373    empty Params property.
374
375 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
376    Link now set up in Loaded method - avoids occasional failure to apply
377    SQL markup on initial open.
378
379 3.  "Employees" example performance improvements when scrolling.
380
381 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
382    TFrame. Force recaching of selected frame to avoid GTK race (results in a
383    random image cached).
384
385 5.  DBControlGrid: Should now react to changes in panel height at run time.
386
387 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
388    even when further rows exist.
389
390 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
391    always be derived from panel height and setting this property can cause confusion.
392    Note for existing projects: to avoid a missing property error at run time,
393    each form using the DBControlGrid must be opened, updated and saved in the IDE
394    in order to remove the property value from the lfm.
395
396
397 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
398
399 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
400    call Prepare before setting parameter values.
401
402 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
403
404 3.  Code tidyup and more robust handling of dsql information result vector.
405
406 4.  Support for centralised handling of transaction status changes. TIBTransaction
407    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
408    and "AfterExecQuery". The first three are called after the same event is called
409    for an IBCustomDataSet descendent using the Transaction. The fourth is called
410    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
411    enable monitoring of transaction status changes for a given transaction to be
412    handled in a single place. For example, when a change to the dataset occurs
413    an indicator can be set that shows the user that in order to save changes,
414    the transaction should be committed.  Rather than doing this per dataset, this
415    can now be done per transaction.
416
417 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
418    the dataset is scrolled. However, any changes to the current row are, by default,
419    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
420    have a new property "DataSetCloseAction" that adds automatic posting of changes
421    on dataset close. If this property is set to dcDiscardChanges (default) then the
422    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
423    then IBX will attempt to post any unsaved changes before the dataset is closed
424    (and after the BeforeClose event handler is called). The exception is when the
425    dataset is being closed as a result of a transaction rollback. In this case,
426    no action is taken and any unsaved  changes are discarded. This avoids both
427    unnecessary overhead and the risk that a validation error may occur in the Post
428    raising an exception and thereby preventing a rollback.
429
430 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
431    In earlier versions, the Display Width was set to the maximum byte width rather than the character
432    width. Display Widths are now corrected by dividing by the max byte width per character.
433    For UTF8 character sets, the byte width is four and hence the Display Width will be
434    the byte width divided by 4. The byte width of each character set is determined
435    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
436    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
437
438 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
439
440 8.  IBLookupComboEditBox: List should now always be restored to full list when the
441    control loses focus. Default Key press default interval reduced to 200ms.
442
443 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
444    when dataset rows are less than visible rows.
445
446 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
447    does not exist or DataSet is empty. More responsive on dataset open. New event
448    OnRestorePosition. Column sort disabled if no header row.
449
450 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
451    while dataset state is dsInsert. Avoids posting errors.
452
453 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
454    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
455
456 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
457
458 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
459    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
460    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
461    always "posts" the current record regardless or whether or not it may be more appropriate
462    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
463    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
464    as the first action of the "Post" method and allows the handler to convert the Post
465    into a Cancel if that is the appropriate action on moving to a different row. This is
466    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
467    raised here, but it may still be more appropriate to validate a post and signal
468    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
469
470 15. On Unix derived systems, the Firebird library name can now be given as a colon
471    separated list. Each library name on the list is tried in turn, in left to right
472    order with the first found being used as the firebird library. By default, on Linux,
473    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
474    overidden by the FBLIB environment variable or the OnGetLibraryName function.
475
476    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
477    then it will still attempt to access the database via the Firebird Server and will
478    require a username and password. If only the pathname is given, then the username
479    and password should be omitted and the unix file permissions are used to grant
480    access.
481
482 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
483
484 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
485    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
486    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
487    corresponds to a row of the linked DataSource. Any data aware control on the
488    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
489
490 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
491   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
492   takes place during database access. This may be useful when there are performance issues with
493   the change of cursor. Setting the property to false suppresses the change of cursor.
494
495 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
496   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
497   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
498   making all changes permanent immediately rather than when the transaction is explicitly
499   committed.
500
501 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
502   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
503
504 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
505
506 Development version only.
507
508 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
509
510 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
511   This is typically used during an "OnBeforeOpen" event handler to manipulate the
512   "Where" and "Having" clauses to implement user specified filters of arbitrary
513   complexity.
514
515 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
516   three new data aware controls dependent on IBX and which make use of the SQL Parser.
517   These are:
518
519   - TIBLookupComboEditBox
520   - TIBDynamicGrid
521   - TIBTreeview
522
523   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
524   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
525   to revise the available list and restrict it to items that are prefixed by the
526   typed text (either case sensitive or case insensitive). Autoinsert allows a
527   newly typed entry to be added to the list dataset and included in the available
528   list items.
529
530   TIBDynamicGrid is a TDBGrid descendent that provides for:
531   - automatic resizing of selected columns to fill the available row length
532   - automatic positioning and sizing of a "totals" control, typically at the
533     column footer, on a per column basis.
534   - DataSet resorting on header row click, sorting the dataset by the selected column.
535     A second click on the same header cell reversed the sort order.
536   - Support for a "Panel Editor". That is on clicking the indicator column, the row
537     is automatically expanded and a panel superimposed on it. The panel can have any
538     number of child controls, typically data aware controls with the same datasource
539     as the grid allowing for editing of additional fields and more complex editors.
540   - Reselection of the same row following resorting.
541   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
542     Its properties are specified on a per column basis and allows for one or more
543     columns to have their values selected from a list provided by a dataset.
544     Autocomplete and autoinsert are also available. The existing picklist editor
545     is unaffected by the extension.
546
547   TIBTreeView is a data aware TCustomTreeView.
548
549 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
550   zero scale will no longer return an error. An Int64 will be returned instead.
551
552 4. TIBTransaction now has events for Before and After Transaction End and a new function
553   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
554
555 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
556   repeated multiple times.
557
558 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
559   check used to get in the way of using Stored Procedures, and "Update or Insert"
560   statements.
561
562 7. Insert, Modify and Delete property Editors now support Query Generation from
563   Stored Procedures.
564
565 8. Three new examples illustrate the use of the new IB Controls
566
567
568 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
569
570 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
571   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
572   Gabor Boros for reporting this problem and for testing the improvements).
573
574 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
575   See readme.field+param.names in the doc folder.
576
577 3. IBX SQL Editors will now automatically add double quotes around column names when the database
578   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
579
580 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
581
582 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
583   actions.
584
585 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
586   thanks to Yuriy Kopnin for pointing this out).
587
588 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
589
590 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
591   for both fields and parameter setting.
592
593 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
594   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
595
596 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
597    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
598
599 11. TIBTable now has a property editor for "MasterFields"
600
601 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the

614 1. In a TIBCustomDataset descendent, a generator now only sets the value when
615   it is null. This allows for alternative user defined setting of the generator
616
617   Many thanks to Julio Jiménez for this fix
618
619 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library

638
639 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
640   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
641
642 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
643   package is changed to do this (which it should do).
644

647 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
648
649 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
650
651 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
