1 < IBX Change Log  version                   (2.0.3) tba, 24 Feb 2017 12:17:53 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 <   changes.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
9 <   include remote system name.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
12 <   tables when data included in output.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
17 <   and timing information to be written to stdout. This may be used to locate
18 <   performance bottlenecks.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 4. SQLParser: only call "OnChanging" event handler when value is different.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
20 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
27  
28 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
23 <   that BindFields is called when the query is next activated. Avoids FieldName
24 <   not found error.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
35 > 3. New API Calls:
36 >        IColumnMetaData.GetStatement
37 >        IColumnMetaData.GetTransaction
38 >        ISQLData.GetStrLength
39 >        IResults.GetStatement
40 >        IAttachment.OpenBlob (using Blob metadata)
41 >        IAttachment.OpenArray (using array metadata)
42  
43 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
33 <   hexadecimal notation.
43 > 4. FBMessages: removal of unused messages
44  
45 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
36 <   using a simple XML format.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
39 <   grants to these objects.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
42 <   dependency problems restoring complex databases.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 7. TIBXScript: This component has been restructured to allow for the processing of
52 <   embedded XML in INSERT statements and to support interactive sources in addition
46 <   to non-interactive data sources such as files.
51 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52 >   where the second character of the parameter name is a numeric.
53  
54 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
54 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 >   This returns the isc_version connection information as one or more lines.
56 >   This is the same information as returned by isql with the -z option.
57  
58 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
59 <   SET SQL DIALECT
60 <   SET TERM
53 <   SET AUTODDL
54 <   SET BAIL
55 <   SET ECHO
56 <   SET COUNT
57 <   SET STATS
58 <   SET NAMES <character set>
58 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 >   compiler option then the Firebird 3 API is no longer compiled in.
61  
62 < 10. IBVersion unit added to hold current IBX Version Number information.
62 > 4. IColumnMetaData: new method.
63  
64 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
65 <    and domain definitions.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
66 <    fully supported.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
70 >   This returns the max. number of characters returned by the "AsString" method
71 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72  
73 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
76 >   If this argument is set to true then SQL parameter names are assumed to be case
77 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 >   sensitive name.
79  
80 < See also doc/IBX4LazarusGuide.pdf for important information on
81 < upgrading to IBX2.
80 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 >   using .AsString.
84  
77 1. Size property of TIBStringField is now the width in characters of the field
78   and not the byte length. This applies only to multi-byte character sets such
79   as UTF8. The original approach aligned with TStringField. However, the TStringField
80   code is not recognised as a bug and hence this change to align the behaviour.
81   The TStringField change is expected in fpc 3.2.0.
85  
83 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
84   true (default) then Size property value saved in the lfm is ignored. Size is
85   always set from the dynamic information read from the database. It is unclear
86   why anyone would want to override this and set Size to false.
86  
87 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
89 <   block.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
92 <   exist when an attempt is made to connect to it (run time only) then an attempt
93 <   is made to create the database.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
92 <   has been successfully created as a result of a call to CreateDatabase or when
97 <   creating a database after it was found not to exist.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 6.  DBControlGrid: a race condition could result in the wrong row image being
95 <    written to the cache. This has been avoided by a trip round the message
96 <    loop before rendering the row image.
94 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 >   and processing internal parameters as statement parameters.
97  
98 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
99 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
105 <    known to risk corrupt rendering of row images when the control is first
106 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
107 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
110 <    a TDateEdit control located on an editor panel.
101 > 5. New function added to IB.pas
102  
103 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 10. DBControlGrid: Removed memory leak when updating rows.
105 >   This allows a Firebird Library to be loaded from an explicit path. use the
106 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 >   the library. It is possible to load Firebird libraries from different locations
108 >   simultaneously, each with a distinct IFirebirdAPI.
109  
110 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
116 <   when target codepage is CP_NONE. This is a workaround for
117 <   http://bugs.freepascal.org/view.php?id=30622.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 2. DBLog option removed from TIBStatisticalService - not supported by server
120 <   since Firebird 1.5.
119 > 3. IServiceManager improved error handling. Interfaces changed:
120 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123  
124 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
125 <   similar.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 4. IBCodePage: updated mapping between codepages and character id.
127 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 >   thus now returns accumulated stats for a select statement from opening a cursor
129 >   up to the last fetch.
130  
131 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
132 <   Firebird. Character sets with a char width of two are not UTF16.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 6. Strings received from the database are now always transliterated into UTF8
135 <   regardless of the database character set or connection character set. This
137 <   is for compatibility with the LCL.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
142 <   read in an entire blob just to get the size of the blob. General performance
143 <   improvement when opening datasets containing blobs.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
148 <   is now used.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
150 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
151   determined.
145  
146 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
156 <   lazarus 1.6.0
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
151 <   compilation error.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
154 >   These return, respectively, true if a connection default character set was
155 >   specified and the character set id of the connection default character set.
156 >   The DefaultCharSetID is cached when the connection is opened and hence does not
157 >   require a database lookup.
158  
159 < 1. No character set specified for connection: when a text blob is retrieved, the
164 <  character set is determined by looking up the native character set using then
165 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
166 <  set as the connection.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
169 <   for Login Dialog returing a change to the database path.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
164 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
165 <   entered value to be saved on a project specific basis (design time only).
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
170 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
177 <   Otherwise, it sets the column text to the selected ListField Value.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
173 <   column width.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
176 <   and a case insensitive search is requested.
175 > 7. IAttachment: Create Database using SQL statement. The username and password
176 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 >   It is now possible to use IAttachment disconnect/connect to reconnect to
178 >   a database for which the initial connection was established by a create
179 >   database sql statement. Available in FPC only.
180  
181 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
186 <   or column ListSource.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
189 <   unprepare) when closing and the text has not changed.
183 > 9. IBUtils code tidy up.
184  
185 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
186 <   Less likely to cause a cursor re-use error on Windows.
185 > 10. Parameter Block interfaces "find" method. As documented, this should have
186 >   returned a nil interface when the item could not be found. Instead, an empty
187 >   interface item was returned. "Find" now works as documented and will return
188 >   a nil interface if the item cannot be found.
189  
190 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
195 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 11. TIBTreeView: Guard against nil destination on record changed
192 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 >    requests with additional parameters. This is to enable support for fb_info_page_contents
194 >    (return of page contents). Response to fb_info_page_contents returned as
195 >    a string with code page CP_NONE.
196  
197 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
198 <    string type with the code page set to reflect the returned field encoding after
201 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
202 <    earlier versions.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
201 <    will now result in transliteration to the code page specified for the Firebird driver
206 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
200 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202  
203 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
204 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
205 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
211 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
212 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
213 <    the GETACP is used to determine the Windows code page.
203 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 >    default connection port to be specified.
206  
207 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
216 <    name used as the lc_ctype when the database was opened. Only valid while the
217 <    Database is connected.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
210 <    id that corresponds to the DefaultCharSetName.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 >   not in locale format but which are recognised by Firebird. Date values that
214 >   cannot be converted to a string using Pascal library are now passed through
215 >   to Firebird as Text Strings.
216  
217 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
218 <   path is given and database attach fails due to access permission issues on the
226 <   temp directory or security database, then the attach is retried with "localhost:"
227 <   prefixing the databasename. This should avoid problems when the database has to
228 <   be accessed by a local (e.g. classic) server and libfbembed is used.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 2. Windows: revised search order for Firebird DLL:
221 <     i.   The Firebird Embedded Server in the application Directory.
222 <     ii.  If the FIREBIRD environment variable is set then the directory this
223 <          points to is searched for the FB Client DLL and then then underlying
234 <          "bin" directory.
235 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
236 <          is used to locate the Firebird installation directory and the underlying
237 <          "bin" directory is searched for the FB Client DLL.
238 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
239 <          are searched for the FB Client DLL.
240 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
241 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
220 > 4. Charset ID problem. When using Firebird 3, with no default database character set
221 >   and a column has a non-default collation specified, an incorrect character set
222 >   id was being reported that could result in a 'division by zero' error when
223 >   used by IBX. This has now been fixed.
224  
225 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
226 <   See doc/readme.scriptengine and example applications.
225 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227 >   the character sets supported can be updated on a per database basis. That is
228 >   it is possible to add a (Firebird) user defined character set to a database.
229  
230 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
231 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
248 <   See dpc/readme.localdatabase and example applications.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
232  
233 < 5. IBDynamicGrid: Reordering on column header click should now also work for
234 <   dynamic columns.
233 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
234 >   in FBOutputBlock.pas and update test suite to include this item.
235  
236 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
254 <   between incrementing/decrementing the lock count and signalling the event.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.

238 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 >   library or finding it by disk location, the PATH environment variable is now also set to
240 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 >   firebird client library dependencies are loaded.
242  
243 < 1.3.2 was never formally released and only made available as beta copies.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
267 <   i.e. when it is a calculated field
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
257 <   This problem was due to a race condition between recalculating row heights and
271 <   determining which row was selected by the mouse click. The row height calculation
272 <   is now deferred by an extra trip round the message loop allowing the row to
273 <   be always calculated on the current grid layout rather than risking it being
274 <   calculated on the grid layout after the expanded row has been shrunk.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
260 <   Windows.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
279 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
280   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
281   to be determined at runtime. See doc/readme.charactersets.html.
262  
263 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
284 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
287 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
288 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
265 > 1. Change syntax to Mode Delphi
266  
267 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
268 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
292 <   implies no truncation.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
297 <   (avoids "Not in Edit Mode" error).
273 > 4. Generics syntax variations for Delphi added
274  
275 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
302 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
280 > 7. Testsuite updated for Delphi
281  
282 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls

283  
284 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
292 > 4. Array Handling: fix problem with text arrays with character set none. When the
293 >   DB connection has a default character set (e.g. UTF8), an error is raised by
294 >   Firebird if the space allocated is not enough to allow for transliteration, even
295 >   though it is not required for character set none.
296  
297 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
317 <     problem with row size when exception is called.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
302 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
305 <     keyed in i.e. when autocomplete not performed
304 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305 >   an array dimension is not mistaken for a named parameter prefix.
306  
307 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
308 <     console mode applications with all LCL required functions (builtin dialogs and
329 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
330 <     not included in your project, IBX should compile and link with a console mode program.
331 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
332 <     console mode application or the IDE will automatically assume that your
333 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
307 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308 >   when Character set is octets. Avoids loss of non printable characters at start of string.
309  
310 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
311 <     to use the built in dialogs and cursor management. IBDialogs is
312 <     included by default if "ibexpress" is in your project source's "uses" clause.
338 <     This should be the case for all projects created through the IDE. This is why
339 <     you do not want to add the ibexpress package to console mode applications. The
340 <     ibexpressconsolemode package has been created to allow console mode programs
341 <     to avoid adding LCL dependencies when using IBX, while still having the
342 <     unit search paths set up correctly.
310 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 >    to enable stats gathering.
313  
314 <     Existing users should check to ensure that the "ibexpress" unit is included in
345 <     each project's source file (*.lpr).
314 > 11. API Version information added as constants to IB.pas
315  
316 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
348 <     exists, you have to first open the package in the IDE and then close it. This
349 <     adds it to the most recently accessed packages list. To make it permanently
350 <     available, add the package name to lazarus' staticpackages.inc file.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 <         Thanks to Julio Jiménez for suggesting support of console mode.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 7.   SQL Parser can now accept quoted strings that include new lines

321  
322 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
357 <     of text on start of edit. This is particularly useful when tabbing to a
358 <     column and then inserting text.
322 > 1. Initial Release
323  
360 9.   New Examples provided for IB Services and ISQLMonitor.
361
362 10. Fix error when writing to blob streams that recorded only the last buffer
363    write in the blob stream. In most cases, this did not cause a problem as the
364    IB Blob Stream is written in a single write. However, with the TDBImage, write
365    of a graphic type prefix was lost which caused a problem when the image could
366        not be automatically recognised.
367
368 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
369    already open" errors due to random numbers used for the cursor name being identical.
370
371 12. IBTable: corrected error that could result in an "Index out of bounds" error
372    when opening the table and the Primary Key is the last or only column in the
373    table. Thanks to Rick Hoover for the fix.
374
375 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
376    of "UTF-8", and update list of available database character sets. Existing
377    users should check the current lc_ctype setting in their applications.
378
379 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
380
381 1.  Firebird Services: avoid List Index error when opening a service with an
382    empty Params property.
383
384 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
385    Link now set up in Loaded method - avoids occasional failure to apply
386    SQL markup on initial open.
387
388 3.  "Employees" example performance improvements when scrolling.
389
390 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
391    TFrame. Force recaching of selected frame to avoid GTK race (results in a
392    random image cached).
393
394 5.  DBControlGrid: Should now react to changes in panel height at run time.
395
396 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
397    even when further rows exist.
398
399 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
400    always be derived from panel height and setting this property can cause confusion.
401    Note for existing projects: to avoid a missing property error at run time,
402    each form using the DBControlGrid must be opened, updated and saved in the IDE
403    in order to remove the property value from the lfm.
404
405
406 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
407
408 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
409    call Prepare before setting parameter values.
410
411 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
412
413 3.  Code tidyup and more robust handling of dsql information result vector.
414
415 4.  Support for centralised handling of transaction status changes. TIBTransaction
416    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
417    and "AfterExecQuery". The first three are called after the same event is called
418    for an IBCustomDataSet descendent using the Transaction. The fourth is called
419    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
420    enable monitoring of transaction status changes for a given transaction to be
421    handled in a single place. For example, when a change to the dataset occurs
422    an indicator can be set that shows the user that in order to save changes,
423    the transaction should be committed.  Rather than doing this per dataset, this
424    can now be done per transaction.
425
426 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
427    the dataset is scrolled. However, any changes to the current row are, by default,
428    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
429    have a new property "DataSetCloseAction" that adds automatic posting of changes
430    on dataset close. If this property is set to dcDiscardChanges (default) then the
431    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
432    then IBX will attempt to post any unsaved changes before the dataset is closed
433    (and after the BeforeClose event handler is called). The exception is when the
434    dataset is being closed as a result of a transaction rollback. In this case,
435    no action is taken and any unsaved  changes are discarded. This avoids both
436    unnecessary overhead and the risk that a validation error may occur in the Post
437    raising an exception and thereby preventing a rollback.
438
439 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
440    In earlier versions, the Display Width was set to the maximum byte width rather than the character
441    width. Display Widths are now corrected by dividing by the max byte width per character.
442    For UTF8 character sets, the byte width is four and hence the Display Width will be
443    the byte width divided by 4. The byte width of each character set is determined
444    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
445    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
446
447 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
448
449 8.  IBLookupComboEditBox: List should now always be restored to full list when the
450    control loses focus. Default Key press default interval reduced to 200ms.
451
452 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
453    when dataset rows are less than visible rows.
454
455 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
456    does not exist or DataSet is empty. More responsive on dataset open. New event
457    OnRestorePosition. Column sort disabled if no header row.
458
459 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
460    while dataset state is dsInsert. Avoids posting errors.
461
462 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
463    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
464
465 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
466
467 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
468    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
469    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
470    always "posts" the current record regardless or whether or not it may be more appropriate
471    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
472    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
473    as the first action of the "Post" method and allows the handler to convert the Post
474    into a Cancel if that is the appropriate action on moving to a different row. This is
475    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
476    raised here, but it may still be more appropriate to validate a post and signal
477    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
478
479 15. On Unix derived systems, the Firebird library name can now be given as a colon
480    separated list. Each library name on the list is tried in turn, in left to right
481    order with the first found being used as the firebird library. By default, on Linux,
482    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
483    overidden by the FBLIB environment variable or the OnGetLibraryName function.
484
485    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
486    then it will still attempt to access the database via the Firebird Server and will
487    require a username and password. If only the pathname is given, then the username
488    and password should be omitted and the unix file permissions are used to grant
489    access.
490
491 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
492
493 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
494    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
495    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
496    corresponds to a row of the linked DataSource. Any data aware control on the
497    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
498
499 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
500   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
501   takes place during database access. This may be useful when there are performance issues with
502   the change of cursor. Setting the property to false suppresses the change of cursor.
503
504 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
505   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
506   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
507   making all changes permanent immediately rather than when the transaction is explicitly
508   committed.
509
510 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
511   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

517 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
518
519 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
520   This is typically used during an "OnBeforeOpen" event handler to manipulate the
521   "Where" and "Having" clauses to implement user specified filters of arbitrary
522   complexity.
523
524 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
525   three new data aware controls dependent on IBX and which make use of the SQL Parser.
526   These are:
527
528   - TIBLookupComboEditBox
529   - TIBDynamicGrid
530   - TIBTreeview
531
532   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
533   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
534   to revise the available list and restrict it to items that are prefixed by the
535   typed text (either case sensitive or case insensitive). Autoinsert allows a
536   newly typed entry to be added to the list dataset and included in the available
537   list items.
538
539   TIBDynamicGrid is a TDBGrid descendent that provides for:
540   - automatic resizing of selected columns to fill the available row length
541   - automatic positioning and sizing of a "totals" control, typically at the
542     column footer, on a per column basis.
543   - DataSet resorting on header row click, sorting the dataset by the selected column.
544     A second click on the same header cell reversed the sort order.
545   - Support for a "Panel Editor". That is on clicking the indicator column, the row
546     is automatically expanded and a panel superimposed on it. The panel can have any
547     number of child controls, typically data aware controls with the same datasource
548     as the grid allowing for editing of additional fields and more complex editors.
549   - Reselection of the same row following resorting.
550   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
551     Its properties are specified on a per column basis and allows for one or more
552     columns to have their values selected from a list provided by a dataset.
553     Autocomplete and autoinsert are also available. The existing picklist editor
554     is unaffected by the extension.
555
556   TIBTreeView is a data aware TCustomTreeView.
557
558 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
559   zero scale will no longer return an error. An Int64 will be returned instead.
560
561 4. TIBTransaction now has events for Before and After Transaction End and a new function
562   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
563
564 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
565   repeated multiple times.
566
567 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
568   check used to get in the way of using Stored Procedures, and "Update or Insert"
569   statements.
570
571 7. Insert, Modify and Delete property Editors now support Query Generation from
572   Stored Procedures.
573
574 8. Three new examples illustrate the use of the new IB Controls

578
579 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
580   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
581   Gabor Boros for reporting this problem and for testing the improvements).
582
583 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
584   See readme.field+param.names in the doc folder.
585
586 3. IBX SQL Editors will now automatically add double quotes around column names when the database
587   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
588
589 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
590
591 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
592   actions.
593
594 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
595   thanks to Yuriy Kopnin for pointing this out).
596
597 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
598
599 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
600   for both fields and parameter setting.
601
602 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
603   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
604
605 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
606    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
607
608 11. TIBTable now has a property editor for "MasterFields"
609
610 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
611    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
612
613 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
614    of settings is unrecognised. Selecting this radio button has no effect on the settings.

619 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
620
621 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
622
623 1. In a TIBCustomDataset descendent, a generator now only sets the value when
624   it is null. This allows for alternative user defined setting of the generator
625
626   Many thanks to Julio Jiménez for this fix
627
628 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
629   and suggests that the user may have forgotten to install it.
630
631 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
632
633 1. Conditional compilation used to limit registration of TIntegerField to
634   Lazarus versions less than 1.1
635
636 2. When a database connection is created, character set is now by default set
637   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
638   1250 to 1254.
639

641 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
642
643 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
644
645
646 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
647
648 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
649   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
650
651 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
652   package is changed to do this (which it should do).
653
654 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
655
656 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
657
658 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
659
660 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
661
662 4. Property editors should now correctly resize.
663
664 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
665   (restored original functionality)
666
667 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
668   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
