4 >   case sensitive
5  
6 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 <   Bug could result in truncated multi-byte character set values.
6 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7  
8 < 3. Changes consequential on moving fbintf character set utility functions from
9 <   IFirebirdAPI to IAttachment.
8 > 3. New API Calls:
9 >        IColumnMetaData.GetStatement
10 >        IColumnMetaData.GetTransaction
11 >        ISQLData.GetStrLength
12 >        IResults.GetStatement

16 > 4. FBMessages: removal of unused messages
17  
18 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 <   results in autocomplete ignoring prefix text.
18 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19  
20 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 <   entering a new name into the text box.
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.

22 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
25 <   include remote system name.
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 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
28 <   tables when data included in output.
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 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
32 <   and timing information to be written to stdout. This may be used to locate
33 <   performance bottlenecks.
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 < 4. SQLParser: only call "OnChanging" event handler when value is different.
35 > 4. IColumnMetaData: new method.
36  
37 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
37 <   that BindFields is called when the query is next activated. Avoids FieldName
38 <   not found error.
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
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 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
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 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
54 <   hexadecimal notation.
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  
49 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
50   using a simple XML format.
58  
52 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
53   grants to these objects.
59  
60 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
56 <   dependency problems restoring complex databases.
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < 7. TIBXScript: This component has been restructured to allow for the processing of
59 <   embedded XML in INSERT statements and to support interactive sources in addition
60 <   to non-interactive data sources such as files.
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
68 <   SET SQL DIALECT
69 <   SET TERM
67 <   SET AUTODDL
68 <   SET BAIL
69 <   SET ECHO
70 <   SET COUNT
71 <   SET STATS
72 <   SET NAMES <character set>
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 < 10. IBVersion unit added to hold current IBX Version Number information.
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 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
77 <    and domain definitions.
74 > 5. New function added to IB.pas
75  
76 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
80 <    fully supported.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
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 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < See also doc/IBX4LazarusGuide.pdf for important information on
89 < upgrading to IBX2.
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 1. Size property of TIBStringField is now the width in characters of the field
93 <   and not the byte length. This applies only to multi-byte character sets such
94 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
95 <   code is not recognised as a bug and hence this change to align the behaviour.
95 <   The TStringField change is expected in fpc 3.2.0.
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 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
98 <   true (default) then Size property value saved in the lfm is ignored. Size is
99 <   always set from the dynamic information read from the database. It is unclear
100 <   why anyone would want to override this and set Size to false.
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
101 <   block.
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 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
105 <   exist when an attempt is made to connect to it (run time only) then an attempt
107 <   is made to create the database.
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
108 <   has been successfully created as a result of a call to CreateDatabase or when
111 <   creating a database after it was found not to exist.
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109  
110 < 6.  DBControlGrid: a race condition could result in the wrong row image being
114 <    written to the cache. This has been avoided by a trip round the message
115 <    loop before rendering the row image.
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
118 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
119 <    known to risk corrupt rendering of row images when the control is first
120 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
121 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
124 <    a TDateEdit control located on an editor panel.
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
128 10. DBControlGrid: Removed memory leak when updating rows.
118  
119 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
124 <   when target codepage is CP_NONE. This is a workaround for
125 <   http://bugs.freepascal.org/view.php?id=30622.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < 2. DBLog option removed from TIBStatisticalService - not supported by server
128 <   since Firebird 1.5.
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 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
142 <   similar.
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < 4. IBCodePage: updated mapping between codepages and character id.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
137 <   Firebird. Character sets with a char width of two are not UTF16.
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < 6. Strings received from the database are now always transliterated into UTF8
143 <   regardless of the database character set or connection character set. This
151 <   is for compatibility with the LCL.
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  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
149 <   read in an entire blob just to get the size of the blob. General performance
150 <   improvement when opening datasets containing blobs.
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. Clearing a  Blob now sets the corresponding field's modified flag.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
162 <   is now used.
156 > 9. IBUtils code tidy up.
157  
158 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
159 <   determined.
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: Recompute column widths after dataset closed and re-opened.
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
166 <   lazarus 1.6.0
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. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
171 <   compilation error.
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
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 < 1. No character set specified for connection: when a text blob is retrieved, the
177 <  character set is determined by looking up the native character set using then
178 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
180 <  set as the connection.
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 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
183 <   for Login Dialog returing a change to the database path.
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
183 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
187 <   entered value to be saved on a project specific basis (design time only).
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
186 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
187 <   Otherwise, it sets the column text to the selected ListField Value.
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 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
191 <   column width.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
194 <   and a case insensitive search is requested.
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 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
199 <   or column ListSource.
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 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
204 <   unprepare) when closing and the text has not changed.
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 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
207 <   Less likely to cause a cursor re-use error on Windows.
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 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
209 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < 11. TIBTreeView: Guard against nil destination on record changed
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 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
214 <    string type with the code page set to reflect the returned field encoding after
215 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
216 <    earlier versions.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
219 <    will now result in transliteration to the code page specified for the Firebird driver
220 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219  
220 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
223 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
224 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
225 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
226 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
227 <    the GETACP is used to determine the Windows code page.
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
223 <    name used as the lc_ctype when the database was opened. Only valid while the
224 <    Database is connected.
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 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
234 <    id that corresponds to the DefaultCharSetName.
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
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. Unix: If Firebird Embedded Server shared object is loaded and a local database
233 <   path is given and database attach fails due to access permission issues on the
240 <   temp directory or security database, then the attach is retried with "localhost:"
241 <   prefixing the databasename. This should avoid problems when the database has to
242 <   be accessed by a local (e.g. classic) server and libfbembed is used.
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234  
244 2. Windows: revised search order for Firebird DLL:
245     i.   The Firebird Embedded Server in the application Directory.
246     ii.  If the FIREBIRD environment variable is set then the directory this
247          points to is searched for the FB Client DLL and then then underlying
248          "bin" directory.
249     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
250          is used to locate the Firebird installation directory and the underlying
251          "bin" directory is searched for the FB Client DLL.
252     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
253          are searched for the FB Client DLL.
254     v.   The PATH Environment variable is used to search for the FB Client DLL.
255     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
235  
236 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
258 <   See doc/readme.scriptengine and example applications.
236 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237  
238 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
261 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
262 <   See dpc/readme.localdatabase and example applications.
238 > 1. Change syntax to Mode Delphi
239  
240 < 5. IBDynamicGrid: Reordering on column header click should now also work for
241 <   dynamic columns.
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.
242  
243 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
244 <   between incrementing/decrementing the lock count and signalling the event.
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
246 > 4. Generics syntax variations for Delphi added
247  
248 < 1.3.2 was never formally released and only made available as beta copies.
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
253 > 7. Testsuite updated for Delphi
254  
255 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
258 <   i.e. when it is a calculated field
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
261 <   This problem was due to a race condition between recalculating row heights and
285 <   determining which row was selected by the mouse click. The row height calculation
286 <   is now deferred by an extra trip round the message loop allowing the row to
287 <   be always calculated on the current grid layout rather than risking it being
288 <   calculated on the grid layout after the expanded row has been shrunk.
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
291 <   Windows.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
266 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
267 <   to be determined at runtime. See doc/readme.charactersets.html.
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 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
298 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
301 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
302 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
272 > 6. Add ISQL style performance statistics collection to IStatement
273  
274 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
275 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
306 <   implies no truncation.
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
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 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
281 <   (avoids "Not in Edit Mode" error).
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 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
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 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
316 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
287 > 11. API Version information added as constants to IB.pas
288  
289 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
289 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290  
291 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
291 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292  
293 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.

326 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
327
328 1.   OnCloseUp Event Handler added to TDBLookupProperties
329
330 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
331     problem with row size when exception is called.
332
333 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
334
335 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
336     in a TCustomComboBox and ignores return key if in a TCustomMemo
337
338 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
339     keyed in i.e. when autocomplete not performed
340
341 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
342     console mode applications with all LCL required functions (builtin dialogs and
343     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
344     not included in your project, IBX should compile and link with a console mode program.
345     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
346     console mode application or the IDE will automatically assume that your
347     application is GUI based. Instead, you should include the ibexpressconsolemode package.
348
349     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
350     to use the built in dialogs and cursor management. IBDialogs is
351     included by default if "ibexpress" is in your project source's "uses" clause.
352     This should be the case for all projects created through the IDE. This is why
353     you do not want to add the ibexpress package to console mode applications. The
354     ibexpressconsolemode package has been created to allow console mode programs
355     to avoid adding LCL dependencies when using IBX, while still having the
356     unit search paths set up correctly.
357
358     Existing users should check to ensure that the "ibexpress" unit is included in
359     each project's source file (*.lpr).
360
361     You may find that in order for the IDE to recognise that ibexpressconsolemode
362     exists, you have to first open the package in the IDE and then close it. This
363     adds it to the most recently accessed packages list. To make it permanently
364     available, add the package name to lazarus' staticpackages.inc file.
365
366         Thanks to Julio Jiménez for suggesting support of console mode.
367
368 7.   SQL Parser can now accept quoted strings that include new lines
369
370 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
371     of text on start of edit. This is particularly useful when tabbing to a
372     column and then inserting text.
373
374 9.   New Examples provided for IB Services and ISQLMonitor.
375
376 10. Fix error when writing to blob streams that recorded only the last buffer
377    write in the blob stream. In most cases, this did not cause a problem as the
378    IB Blob Stream is written in a single write. However, with the TDBImage, write
379    of a graphic type prefix was lost which caused a problem when the image could
380        not be automatically recognised.
381
382 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
383    already open" errors due to random numbers used for the cursor name being identical.
384
385 12. IBTable: corrected error that could result in an "Index out of bounds" error
386    when opening the table and the Primary Key is the last or only column in the
387    table. Thanks to Rick Hoover for the fix.
388
389 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
390    of "UTF-8", and update list of available database character sets. Existing
391    users should check the current lc_ctype setting in their applications.
392
393 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
394
395 1.  Firebird Services: avoid List Index error when opening a service with an
396    empty Params property.
397
398 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
399    Link now set up in Loaded method - avoids occasional failure to apply
400    SQL markup on initial open.
401
402 3.  "Employees" example performance improvements when scrolling.
403
404 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
405    TFrame. Force recaching of selected frame to avoid GTK race (results in a
406    random image cached).
407
408 5.  DBControlGrid: Should now react to changes in panel height at run time.
409
410 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
411    even when further rows exist.
412
413 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
414    always be derived from panel height and setting this property can cause confusion.
415    Note for existing projects: to avoid a missing property error at run time,
416    each form using the DBControlGrid must be opened, updated and saved in the IDE
417    in order to remove the property value from the lfm.
418
419
420 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
421
422 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
423    call Prepare before setting parameter values.
424
425 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
426
427 3.  Code tidyup and more robust handling of dsql information result vector.
428
429 4.  Support for centralised handling of transaction status changes. TIBTransaction
430    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
431    and "AfterExecQuery". The first three are called after the same event is called
432    for an IBCustomDataSet descendent using the Transaction. The fourth is called
433    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
434    enable monitoring of transaction status changes for a given transaction to be
435    handled in a single place. For example, when a change to the dataset occurs
436    an indicator can be set that shows the user that in order to save changes,
437    the transaction should be committed.  Rather than doing this per dataset, this
438    can now be done per transaction.
439
440 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
441    the dataset is scrolled. However, any changes to the current row are, by default,
442    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
443    have a new property "DataSetCloseAction" that adds automatic posting of changes
444    on dataset close. If this property is set to dcDiscardChanges (default) then the
445    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
446    then IBX will attempt to post any unsaved changes before the dataset is closed
447    (and after the BeforeClose event handler is called). The exception is when the
448    dataset is being closed as a result of a transaction rollback. In this case,
449    no action is taken and any unsaved  changes are discarded. This avoids both
450    unnecessary overhead and the risk that a validation error may occur in the Post
451    raising an exception and thereby preventing a rollback.
452
453 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
454    In earlier versions, the Display Width was set to the maximum byte width rather than the character
455    width. Display Widths are now corrected by dividing by the max byte width per character.
456    For UTF8 character sets, the byte width is four and hence the Display Width will be
457    the byte width divided by 4. The byte width of each character set is determined
458    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
459    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
460
461 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
462
463 8.  IBLookupComboEditBox: List should now always be restored to full list when the
464    control loses focus. Default Key press default interval reduced to 200ms.
465
466 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
467    when dataset rows are less than visible rows.
468
469 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
470    does not exist or DataSet is empty. More responsive on dataset open. New event
471    OnRestorePosition. Column sort disabled if no header row.
472
473 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
474    while dataset state is dsInsert. Avoids posting errors.
475
476 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
477    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
478
479 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
480
481 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
482    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
483    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
484    always "posts" the current record regardless or whether or not it may be more appropriate
485    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
486    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
487    as the first action of the "Post" method and allows the handler to convert the Post
488    into a Cancel if that is the appropriate action on moving to a different row. This is
489    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
490    raised here, but it may still be more appropriate to validate a post and signal
491    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
492
493 15. On Unix derived systems, the Firebird library name can now be given as a colon
494    separated list. Each library name on the list is tried in turn, in left to right
495    order with the first found being used as the firebird library. By default, on Linux,
496    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
497    overidden by the FBLIB environment variable or the OnGetLibraryName function.
498
499    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
500    then it will still attempt to access the database via the Firebird Server and will
501    require a username and password. If only the pathname is given, then the username
502    and password should be omitted and the unix file permissions are used to grant
503    access.
504
505 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
506
507 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
508    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
509    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
510    corresponds to a row of the linked DataSource. Any data aware control on the
511    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
512
513 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
514   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
515   takes place during database access. This may be useful when there are performance issues with
516   the change of cursor. Setting the property to false suppresses the change of cursor.
517
518 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
519   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
520   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
521   making all changes permanent immediately rather than when the transaction is explicitly
522   committed.
523
524 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
525   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
526
527 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
528
529 Development version only.
530
531 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
532
533 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
534   This is typically used during an "OnBeforeOpen" event handler to manipulate the
535   "Where" and "Having" clauses to implement user specified filters of arbitrary
536   complexity.
537
538 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
539   three new data aware controls dependent on IBX and which make use of the SQL Parser.
540   These are:
541
542   - TIBLookupComboEditBox
543   - TIBDynamicGrid
544   - TIBTreeview
545
546   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
547   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
548   to revise the available list and restrict it to items that are prefixed by the
549   typed text (either case sensitive or case insensitive). Autoinsert allows a
550   newly typed entry to be added to the list dataset and included in the available
551   list items.
552
553   TIBDynamicGrid is a TDBGrid descendent that provides for:
554   - automatic resizing of selected columns to fill the available row length
555   - automatic positioning and sizing of a "totals" control, typically at the
556     column footer, on a per column basis.
557   - DataSet resorting on header row click, sorting the dataset by the selected column.
558     A second click on the same header cell reversed the sort order.
559   - Support for a "Panel Editor". That is on clicking the indicator column, the row
560     is automatically expanded and a panel superimposed on it. The panel can have any
561     number of child controls, typically data aware controls with the same datasource
562     as the grid allowing for editing of additional fields and more complex editors.
563   - Reselection of the same row following resorting.
564   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
565     Its properties are specified on a per column basis and allows for one or more
566     columns to have their values selected from a list provided by a dataset.
567     Autocomplete and autoinsert are also available. The existing picklist editor
568     is unaffected by the extension.
569
570   TIBTreeView is a data aware TCustomTreeView.
571
572 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
573   zero scale will no longer return an error. An Int64 will be returned instead.
574
575 4. TIBTransaction now has events for Before and After Transaction End and a new function
576   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
577
578 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
579   repeated multiple times.
580
581 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
582   check used to get in the way of using Stored Procedures, and "Update or Insert"
583   statements.
584
585 7. Insert, Modify and Delete property Editors now support Query Generation from
586   Stored Procedures.
587
588 8. Three new examples illustrate the use of the new IB Controls
589
590
591 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
592
593 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
594   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
595   Gabor Boros for reporting this problem and for testing the improvements).
596
597 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
598   See readme.field+param.names in the doc folder.
599
600 3. IBX SQL Editors will now automatically add double quotes around column names when the database
601   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
602
603 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
604
605 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
606   actions.
607
608 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
609   thanks to Yuriy Kopnin for pointing this out).
610
611 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
612
613 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
614   for both fields and parameter setting.
615
616 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
617   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
618
619 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
620    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
621
622 11. TIBTable now has a property editor for "MasterFields"
623
624 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
625    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
626
627 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
628    of settings is unrecognised. Selecting this radio button has no effect on the settings.

636
637 1. In a TIBCustomDataset descendent, a generator now only sets the value when
638   it is null. This allows for alternative user defined setting of the generator
639
640   Many thanks to Julio Jiménez for this fix
641
642 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
643   and suggests that the user may have forgotten to install it.

646
647 1. Conditional compilation used to limit registration of TIntegerField to
648   Lazarus versions less than 1.1
649
650 2. When a database connection is created, character set is now by default set
651   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
652   1250 to 1254.

660 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
661
662 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
663   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
664
665 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
666   package is changed to do this (which it should do).
667
668 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
669
670 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
671
672 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
673
674 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
675
676 4. Property editors should now correctly resize.
677
678 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
679   (restored original functionality)
680
681 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
682   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
