1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
4 <   path is given and database attach fails due to access permission issues on the
5 <   temp directory or security database, then the attach is retried with "localhost:"
6 <   prefixing the databasename. This should avoid problems when the database has to
7 <   be accessed by a local (e.g. classic) server and libfbembed is used.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. Windows: revised search order for Firebird DLL:
7 <     i.   The Firebird Embedded Server in the application Directory.
8 <     ii.  If the FIREBIRD environment variable is set then the directory this
9 <          points to is searched for the FB Client DLL and then then underlying
10 <          "bin" directory.
14 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
15 <          is used to locate the Firebird installation directory and the underlying
16 <          "bin" directory is searched for the FB Client DLL.
17 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
18 <          are searched for the FB Client DLL.
19 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
20 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
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. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
23 <   See doc/readme.scriptengine and example applications.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
26 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
27 <   See dpc/readme.localdatabase and example applications.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. IBDynamicGrid: Reordering on column header click should now also work for
17 <   dynamic columns.
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. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
24 <   between incrementing/decrementing the lock count and signalling the event.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
35 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
27  
28 < 1.3.2 was never formally released and only made available as beta copies.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
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 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
46 <   i.e. when it is a calculated field
43 > 4. FBMessages: removal of unused messages
44  
45 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
49 <   This problem was due to a race condition between recalculating row heights and
50 <   determining which row was selected by the mouse click. The row height calculation
51 <   is now deferred by an extra trip round the message loop allowing the row to
52 <   be always calculated on the current grid layout rather than risking it being
53 <   calculated on the grid layout after the expanded row has been shrunk.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
56 <   Windows.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
59 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
60 <   to be determined at runtime. See doc/readme.charactersets.html.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
52 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
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 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
55 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
56 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
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 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
59 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
60 <   implies no truncation.
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. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
62 > 4. IColumnMetaData: new method.
63  
64 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
65 <   (avoids "Not in Edit Mode" error).
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
71 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
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. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
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 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
80 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 >   using .AsString.
84  
89 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
85  
91 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
86  
87 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
96 <     problem with row size when exception is called.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
95 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
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 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
99 <     keyed in i.e. when autocomplete not performed
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 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
107 <     console mode applications with all LCL required functions (builtin dialogs and
108 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
109 <     not included in your project, IBX should compile and link with a console mode program.
110 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
111 <     console mode application or the IDE will automatically assume that your
112 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
101 > 5. New function added to IB.pas
102  
103 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
115 <     to use the built in dialogs and cursor management. IBDialogs is
116 <     included by default if "ibexpress" is in your project source's "uses" clause.
117 <     This should be the case for all projects created through the IDE. This is why
118 <     you do not want to add the ibexpress package to console mode applications. The
119 <     ibexpressconsolemode package has been created to allow console mode programs
120 <     to avoid adding LCL dependencies when using IBX, while still having the
121 <     unit search paths set up correctly.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 <     Existing users should check to ensure that the "ibexpress" unit is included in
106 <     each project's source file (*.lpr).
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 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
127 <     exists, you have to first open the package in the IDE and then close it. This
128 <     adds it to the most recently accessed packages list. To make it permanently
129 <     available, add the package name to lazarus' staticpackages.inc file.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 <         Thanks to Julio Jiménez for suggesting support of console mode.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 7.   SQL Parser can now accept quoted strings that include new lines
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
120 <     of text on start of edit. This is particularly useful when tabbing to a
121 <     column and then inserting text.
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 < 9.   New Examples provided for IB Services and ISQLMonitor.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 10. Fix error when writing to blob streams that recorded only the last buffer
128 <    write in the blob stream. In most cases, this did not cause a problem as the
129 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
144 <    of a graphic type prefix was lost which caused a problem when the image could
145 <        not be automatically recognised.
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 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
132 <    already open" errors due to random numbers used for the cursor name being identical.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
135 <    when opening the table and the Primary Key is the last or only column in the
152 <    table. Thanks to Rick Hoover for the fix.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
155 <    of "UTF-8", and update list of available database character sets. Existing
156 <    users should check the current lc_ctype setting in their applications.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 1.  Firebird Services: avoid List Index error when opening a service with an
161 <    empty Params property.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
164 <    Link now set up in Loaded method - avoids occasional failure to apply
165 <    SQL markup on initial open.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
167 3.  "Employees" example performance improvements when scrolling.
145  
146 < 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
170 <    TFrame. Force recaching of selected frame to avoid GTK race (results in a
171 <    random image cached).
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 5.  DBControlGrid: Should now react to changes in panel height at run time.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
151 <    even when further rows exist.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
155 <    always be derived from panel height and setting this property can cause confusion.
156 <    Note for existing projects: to avoid a missing property error at run time,
157 <    each form using the DBControlGrid must be opened, updated and saved in the IDE
182 <    in order to remove the property value from the lfm.
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 + 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
164 <    call Prepare before setting parameter values.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 3.  Code tidyup and more robust handling of dsql information result vector.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 4.  Support for centralised handling of transaction status changes. TIBTransaction
176 <    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
177 <    and "AfterExecQuery". The first three are called after the same event is called
178 <    for an IBCustomDataSet descendent using the Transaction. The fourth is called
179 <    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
199 <    enable monitoring of transaction status changes for a given transaction to be
200 <    handled in a single place. For example, when a change to the dataset occurs
201 <    an indicator can be set that shows the user that in order to save changes,
202 <    the transaction should be committed.  Rather than doing this per dataset, this
203 <    can now be done per transaction.
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 < 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
206 <    the dataset is scrolled. However, any changes to the current row are, by default,
207 <    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
208 <    have a new property "DataSetCloseAction" that adds automatic posting of changes
209 <    on dataset close. If this property is set to dcDiscardChanges (default) then the
210 <    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
211 <    then IBX will attempt to post any unsaved changes before the dataset is closed
212 <    (and after the BeforeClose event handler is called). The exception is when the
213 <    dataset is being closed as a result of a transaction rollback. In this case,
214 <    no action is taken and any unsaved  changes are discarded. This avoids both
215 <    unnecessary overhead and the risk that a validation error may occur in the Post
216 <    raising an exception and thereby preventing a rollback.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
219 <    In earlier versions, the Display Width was set to the maximum byte width rather than the character
220 <    width. Display Widths are now corrected by dividing by the max byte width per character.
221 <    For UTF8 character sets, the byte width is four and hence the Display Width will be
222 <    the byte width divided by 4. The byte width of each character set is determined
223 <    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
224 <    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
183 > 9. IBUtils code tidy up.
184  
185 < 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
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 < 8.  IBLookupComboEditBox: List should now always be restored to full list when the
229 <    control loses focus. Default Key press default interval reduced to 200ms.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
193 <    when dataset rows are less than visible rows.
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 < 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
198 <    does not exist or DataSet is empty. More responsive on dataset open. New event
236 <    OnRestorePosition. Column sort disabled if no header row.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
201 <    while dataset state is dsInsert. Avoids posting errors.
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.

203 < 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
204 <    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
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 < 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.

208  
209 < 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
210 <    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
248 <    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
249 <    always "posts" the current record regardless or whether or not it may be more appropriate
250 <    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
251 <    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
252 <    as the first action of the "Post" method and allows the handler to convert the Post
253 <    into a Cancel if that is the appropriate action on moving to a different row. This is
254 <    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
255 <    raised here, but it may still be more appropriate to validate a post and signal
256 <    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 15. On Unix derived systems, the Firebird library name can now be given as a colon
213 <    separated list. Each library name on the list is tried in turn, in left to right
214 <    order with the first found being used as the firebird library. By default, on Linux,
215 <    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
262 <    overidden by the FBLIB environment variable or the OnGetLibraryName function.
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 <    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
218 <    then it will still attempt to access the database via the Firebird Server and will
266 <    require a username and password. If only the pathname is given, then the username
267 <    and password should be omitted and the unix file permissions are used to grant
268 <    access.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
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 < 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
226 <    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
227 <    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
228 <    corresponds to a row of the linked DataSource. Any data aware control on the
276 <    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
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 < 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
231 <   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
280 <   takes place during database access. This may be useful when there are performance issues with
281 <   the change of cursor. Setting the property to false suppresses the change of cursor.
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 < 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
234 <   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
285 <   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
286 <   making all changes permanent immediately rather than when the transaction is explicitly
287 <   committed.
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 < 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
290 <   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
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 < Development version only.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
299 <   This is typically used during an "OnBeforeOpen" event handler to manipulate the
300 <   "Where" and "Having" clauses to implement user specified filters of arbitrary
301 <   complexity.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
250 <   three new data aware controls dependent on IBX and which make use of the SQL Parser.
251 <   These are:
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 <   - TIBLookupComboEditBox
308 <   - TIBDynamicGrid
309 <   - TIBTreeview
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 <   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
257 <   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
313 <   to revise the available list and restrict it to items that are prefixed by the
314 <   typed text (either case sensitive or case insensitive). Autoinsert allows a
315 <   newly typed entry to be added to the list dataset and included in the available
316 <   list items.
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 <   TIBDynamicGrid is a TDBGrid descendent that provides for:
260 <   - automatic resizing of selected columns to fill the available row length
320 <   - automatic positioning and sizing of a "totals" control, typically at the
321 <     column footer, on a per column basis.
322 <   - DataSet resorting on header row click, sorting the dataset by the selected column.
323 <     A second click on the same header cell reversed the sort order.
324 <   - Support for a "Panel Editor". That is on clicking the indicator column, the row
325 <     is automatically expanded and a panel superimposed on it. The panel can have any
326 <     number of child controls, typically data aware controls with the same datasource
327 <     as the grid allowing for editing of additional fields and more complex editors.
328 <   - Reselection of the same row following resorting.
329 <   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
330 <     Its properties are specified on a per column basis and allows for one or more
331 <     columns to have their values selected from a list provided by a dataset.
332 <     Autocomplete and autoinsert are also available. The existing picklist editor
333 <     is unaffected by the extension.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
335   TIBTreeView is a data aware TCustomTreeView.
262  
263 < 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
338 <   zero scale will no longer return an error. An Int64 will be returned instead.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 4. TIBTransaction now has events for Before and After Transaction End and a new function
341 <   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
265 > 1. Change syntax to Mode Delphi
266  
267 < 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
268 <   repeated multiple times.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
271 <   check used to get in the way of using Stored Procedures, and "Update or Insert"
348 <   statements.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 7. Insert, Modify and Delete property Editors now support Query Generation from
351 <   Stored Procedures.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 8. Three new examples illustrate the use of the new IB Controls
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 + 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
280 > 7. Testsuite updated for Delphi
281  
282 < 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
359 <   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
360 <   Gabor Boros for reporting this problem and for testing the improvements).
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
285 <   See readme.field+param.names in the doc folder.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 3. IBX SQL Editors will now automatically add double quotes around column names when the database
288 <   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
293 <   actions.
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 < 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
374 <   thanks to Yuriy Kopnin for pointing this out).
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
302 <   for both fields and parameter setting.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
305 <   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
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 < 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
308 <    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
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 < 11. TIBTable now has a property editor for "MasterFields"
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 < 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
390 <    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
393 <    of settings is unrecognised. Selecting this radio button has no effect on the settings.
394 <  
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.

322 > 1. Initial Release
323  
402 1. In a TIBCustomDataset descendent, a generator now only sets the value when
403   it is null. This allows for alternative user defined setting of the generator
404
405   Many thanks to Julio Jiménez for this fix
406
407 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
408   and suggests that the user may have forgotten to install it.
409
410 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
411
412 1. Conditional compilation used to limit registration of TIntegerField to
413   Lazarus versions less than 1.1
414
415 2. When a database connection is created, character set is now by default set
416   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
417   1250 to 1254.
418

422 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
423
424
425 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
426
427 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
428   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
429
430 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
431   package is changed to do this (which it should do).
432
433 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
434
435 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
436
437 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
438
439 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
440
441 4. Property editors should now correctly resize.
442
443 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
444   (restored original functionality)
445
446 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
447   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
