1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
4 <   when target codepage is CP_NONE. This is a workaround for
5 <   http://bugs.freepascal.org/view.php?id=30622.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. DBLog option removed from TIBStatisticalService - not supported by server
7 <   since Firebird 1.5.
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
11 <   similar.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. IBCodePage: updated mapping between codepages and character id.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
17 <   Firebird. Character sets with a char width of two are not UTF16.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 6. Strings received from the database are now always transliterated into UTF8
24 <   regardless of the database character set or connection character set. This
25 <   is for compatibility with the LCL.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
22 IBX Change Log  version                                     (1.4-2) Sat, 16 Jul 2016 13:25:48 +0100
27  
28 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
25 <   read in an entire blob just to get the size of the blob. General performance
26 <   improvement when opening datasets containing blobs.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
31 <   is now used.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
36 <   determined.
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 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
43 > 4. FBMessages: removal of unused messages
44  
45 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
39 <   lazarus 1.6.0
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
42 <   compilation error.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 1. No character set specified for connection: when a text blob is retrieved, the
52 <  character set is determined by looking up the native character set using then
48 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
49 <  set as the connection.
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 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
55 <   for Login Dialog returing a change to the database path.
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 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
59 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
60 <   entered value to be saved on a project specific basis (design time only).
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 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
59 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
60 <   Otherwise, it sets the column text to the selected ListField Value.
62 > 4. IColumnMetaData: new method.
63  
64 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
65 <   column width.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
66 <   and a case insensitive search is requested.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
71 <   or column ListSource.
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 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
74 <   unprepare) when closing and the text has not changed.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
77 <   Less likely to cause a cursor re-use error on Windows.
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 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
81 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
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  
80 11. TIBTreeView: Guard against nil destination on record changed
85  
82 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
83    string type with the code page set to reflect the returned field encoding after
84    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
85    earlier versions.
86  
87 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
88 <    will now result in transliteration to the code page specified for the Firebird driver
89 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
92 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
93 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
94 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
95 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
96 <    the GETACP is used to determine the Windows code page.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
92 <    name used as the lc_ctype when the database was opened. Only valid while the
100 <    Database is connected.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
95 <    id that corresponds to the DefaultCharSetName.
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 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
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 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
108 <   path is given and database attach fails due to access permission issues on the
109 <   temp directory or security database, then the attach is retried with "localhost:"
110 <   prefixing the databasename. This should avoid problems when the database has to
111 <   be accessed by a local (e.g. classic) server and libfbembed is used.
101 > 5. New function added to IB.pas
102  
103 < 2. Windows: revised search order for Firebird DLL:
114 <     i.   The Firebird Embedded Server in the application Directory.
115 <     ii.  If the FIREBIRD environment variable is set then the directory this
116 <          points to is searched for the FB Client DLL and then then underlying
117 <          "bin" directory.
118 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
119 <          is used to locate the Firebird installation directory and the underlying
120 <          "bin" directory is searched for the FB Client DLL.
121 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
122 <          are searched for the FB Client DLL.
123 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
124 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
106 <   See doc/readme.scriptengine and example applications.
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 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
130 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
131 <   See dpc/readme.localdatabase and example applications.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 5. IBDynamicGrid: Reordering on column header click should now also work for
113 <   dynamic columns.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
116 <   between incrementing/decrementing the lock count and signalling the event.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
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 < 1.3.2 was never formally released and only made available as beta copies.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
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 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
150 <   i.e. when it is a calculated field
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
153 <   This problem was due to a race condition between recalculating row heights and
154 <   determining which row was selected by the mouse click. The row height calculation
155 <   is now deferred by an extra trip round the message loop allowing the row to
156 <   be always calculated on the current grid layout rather than risking it being
157 <   calculated on the grid layout after the expanded row has been shrunk.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
160 <   Windows.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
163 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
164 <   to be determined at runtime. See doc/readme.charactersets.html.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
166 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
167   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
145  
146 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
170 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
171 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
174 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
175 <   implies no truncation.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
155 <   (avoids "Not in Edit Mode" error).
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 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
185 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
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 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
183 > 9. IBUtils code tidy up.
184  
185 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
186 <     problem with row size when exception is called.
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 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
193 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
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 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
198 <     keyed in i.e. when autocomplete not performed
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
201 <     console mode applications with all LCL required functions (builtin dialogs and
212 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
213 <     not included in your project, IBX should compile and link with a console mode program.
214 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
215 <     console mode application or the IDE will automatically assume that your
216 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
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 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
204 <     to use the built in dialogs and cursor management. IBDialogs is
205 <     included by default if "ibexpress" is in your project source's "uses" clause.
221 <     This should be the case for all projects created through the IDE. This is why
222 <     you do not want to add the ibexpress package to console mode applications. The
223 <     ibexpressconsolemode package has been created to allow console mode programs
224 <     to avoid adding LCL dependencies when using IBX, while still having the
225 <     unit search paths set up correctly.
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 <     Existing users should check to ensure that the "ibexpress" unit is included in
228 <     each project's source file (*.lpr).
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
210 <     exists, you have to first open the package in the IDE and then close it. This
232 <     adds it to the most recently accessed packages list. To make it permanently
233 <     available, add the package name to lazarus' staticpackages.inc file.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.

212 <         Thanks to Julio Jiménez for suggesting support of console mode.
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values

219  
220 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
221 <     of text on start of edit. This is particularly useful when tabbing to a
222 <     column and then inserting text.
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

224  
225 < 9.   New Examples provided for IB Services and ISQLMonitor.
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 < 10. Fix error when writing to blob streams that recorded only the last buffer
231 <    write in the blob stream. In most cases, this did not cause a problem as the
247 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
248 <    of a graphic type prefix was lost which caused a problem when the image could
249 <        not be automatically recognised.
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 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
234 <    already open" errors due to random numbers used for the cursor name being identical.
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 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
255 <    when opening the table and the Primary Key is the last or only column in the
256 <    table. Thanks to Rick Hoover for the fix.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
239 <    of "UTF-8", and update list of available database character sets. Existing
240 <    users should check the current lc_ctype setting in their applications.
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 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 1.  Firebird Services: avoid List Index error when opening a service with an
265 <    empty Params property.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
268 <    Link now set up in Loaded method - avoids occasional failure to apply
269 <    SQL markup on initial open.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 3.  "Employees" example performance improvements when scrolling.
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.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
274 <    TFrame. Force recaching of selected frame to avoid GTK race (results in a
275 <    random image cached).
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 5.  DBControlGrid: Should now react to changes in panel height at run time.
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.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
260 <    even when further rows exist.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
282 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
283    always be derived from panel height and setting this property can cause confusion.
284    Note for existing projects: to avoid a missing property error at run time,
285    each form using the DBControlGrid must be opened, updated and saved in the IDE
286    in order to remove the property value from the lfm.

264  
265 < IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
265 > 1. Change syntax to Mode Delphi
266  
267 < 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
268 <    call Prepare before setting parameter values.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 3.  Code tidyup and more robust handling of dsql information result vector.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 4.  Support for centralised handling of transaction status changes. TIBTransaction
276 <    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
300 <    and "AfterExecQuery". The first three are called after the same event is called
301 <    for an IBCustomDataSet descendent using the Transaction. The fourth is called
302 <    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
303 <    enable monitoring of transaction status changes for a given transaction to be
304 <    handled in a single place. For example, when a change to the dataset occurs
305 <    an indicator can be set that shows the user that in order to save changes,
306 <    the transaction should be committed.  Rather than doing this per dataset, this
307 <    can now be done per transaction.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
310 <    the dataset is scrolled. However, any changes to the current row are, by default,
311 <    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
312 <    have a new property "DataSetCloseAction" that adds automatic posting of changes
313 <    on dataset close. If this property is set to dcDiscardChanges (default) then the
314 <    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
315 <    then IBX will attempt to post any unsaved changes before the dataset is closed
316 <    (and after the BeforeClose event handler is called). The exception is when the
317 <    dataset is being closed as a result of a transaction rollback. In this case,
318 <    no action is taken and any unsaved  changes are discarded. This avoids both
319 <    unnecessary overhead and the risk that a validation error may occur in the Post
320 <    raising an exception and thereby preventing a rollback.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
323 <    In earlier versions, the Display Width was set to the maximum byte width rather than the character
324 <    width. Display Widths are now corrected by dividing by the max byte width per character.
325 <    For UTF8 character sets, the byte width is four and hence the Display Width will be
326 <    the byte width divided by 4. The byte width of each character set is determined
327 <    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
328 <    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
280 > 7. Testsuite updated for Delphi
281  
282 < 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 8.  IBLookupComboEditBox: List should now always be restored to full list when the
285 <    control loses focus. Default Key press default interval reduced to 200ms.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
288 <    when dataset rows are less than visible rows.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
339 <    does not exist or DataSet is empty. More responsive on dataset open. New event
340 <    OnRestorePosition. Column sort disabled if no header row.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
293 <    while dataset state is dsInsert. Avoids posting errors.
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 < 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
346 <    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
302 <    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
352 <    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
353 <    always "posts" the current record regardless or whether or not it may be more appropriate
354 <    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
355 <    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
356 <    as the first action of the "Post" method and allows the handler to convert the Post
357 <    into a Cancel if that is the appropriate action on moving to a different row. This is
358 <    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
359 <    raised here, but it may still be more appropriate to validate a post and signal
360 <    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 15. On Unix derived systems, the Firebird library name can now be given as a colon
305 <    separated list. Each library name on the list is tried in turn, in left to right
364 <    order with the first found being used as the firebird library. By default, on Linux,
365 <    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
366 <    overidden by the FBLIB environment variable or the OnGetLibraryName function.
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 <    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
308 <    then it will still attempt to access the database via the Firebird Server and will
370 <    require a username and password. If only the pathname is given, then the username
371 <    and password should be omitted and the unix file permissions are used to grant
372 <    access.
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 < IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
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 < 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
377 <    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
378 <    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
379 <    corresponds to a row of the linked DataSource. Any data aware control on the
380 <    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
383 <   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
384 <   takes place during database access. This may be useful when there are performance issues with
385 <   the change of cursor. Setting the property to false suppresses the change of cursor.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
388 <   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
389 <   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
390 <   making all changes permanent immediately rather than when the transaction is explicitly
391 <   committed.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
394 <   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

400 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
401
402 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
403   This is typically used during an "OnBeforeOpen" event handler to manipulate the
404   "Where" and "Having" clauses to implement user specified filters of arbitrary
405   complexity.
406
407 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
408   three new data aware controls dependent on IBX and which make use of the SQL Parser.
409   These are:
410
411   - TIBLookupComboEditBox
412   - TIBDynamicGrid
413   - TIBTreeview
414
415   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
416   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
417   to revise the available list and restrict it to items that are prefixed by the
418   typed text (either case sensitive or case insensitive). Autoinsert allows a
419   newly typed entry to be added to the list dataset and included in the available
420   list items.
421
422   TIBDynamicGrid is a TDBGrid descendent that provides for:
423   - automatic resizing of selected columns to fill the available row length
424   - automatic positioning and sizing of a "totals" control, typically at the
425     column footer, on a per column basis.
426   - DataSet resorting on header row click, sorting the dataset by the selected column.
427     A second click on the same header cell reversed the sort order.
428   - Support for a "Panel Editor". That is on clicking the indicator column, the row
429     is automatically expanded and a panel superimposed on it. The panel can have any
430     number of child controls, typically data aware controls with the same datasource
431     as the grid allowing for editing of additional fields and more complex editors.
432   - Reselection of the same row following resorting.
433   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
434     Its properties are specified on a per column basis and allows for one or more
435     columns to have their values selected from a list provided by a dataset.
436     Autocomplete and autoinsert are also available. The existing picklist editor
437     is unaffected by the extension.
438
439   TIBTreeView is a data aware TCustomTreeView.
440
441 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
442   zero scale will no longer return an error. An Int64 will be returned instead.
443
444 4. TIBTransaction now has events for Before and After Transaction End and a new function
445   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
446
447 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
448   repeated multiple times.
449
450 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
451   check used to get in the way of using Stored Procedures, and "Update or Insert"
452   statements.
453
454 7. Insert, Modify and Delete property Editors now support Query Generation from
455   Stored Procedures.
456
457 8. Three new examples illustrate the use of the new IB Controls
458
459
460 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
461
462 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
463   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
464   Gabor Boros for reporting this problem and for testing the improvements).
465
466 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
467   See readme.field+param.names in the doc folder.
468
469 3. IBX SQL Editors will now automatically add double quotes around column names when the database
470   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
471
472 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
473
474 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
475   actions.
476
477 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
478   thanks to Yuriy Kopnin for pointing this out).
479
480 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
481
482 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
483   for both fields and parameter setting.
484
485 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
486   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
487
488 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
489    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
490
491 11. TIBTable now has a property editor for "MasterFields"
492
493 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
494    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
495
496 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
497    of settings is unrecognised. Selecting this radio button has no effect on the settings.

503
504 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
505
506 1. In a TIBCustomDataset descendent, a generator now only sets the value when
507   it is null. This allows for alternative user defined setting of the generator
508
509   Many thanks to Julio Jiménez for this fix
510
511 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
512   and suggests that the user may have forgotten to install it.
513
514 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
515
516 1. Conditional compilation used to limit registration of TIntegerField to
517   Lazarus versions less than 1.1
518
519 2. When a database connection is created, character set is now by default set
520   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
521   1250 to 1254.
522

527
528
529 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
530
531 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
532   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
533
534 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
535   package is changed to do this (which it should do).
536
537 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
538
539 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
540
541 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
542
543 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
544
545 4. Property editors should now correctly resize.
546
547 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
548   (restored original functionality)
549
550 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
551   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
