1 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
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. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
10 <   i.e. when it is a calculated field
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
17 <   This problem was due to a race condition between recalculating row heights and
18 <   determining which row was selected by the mouse click. The row height calculation
19 <   is now deferred by an extra trip round the message loop allowing the row to
20 <   be always calculated on the current grid layout rather than risking it being
21 <   calculated on the grid layout after the expanded row has been shrunk.
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. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
24 <   Windows.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
22 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
23   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
24   to be determined at runtime.
27  
28 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
27 <   TWideStringField. This field type is used with the character size reported by Firebird is two.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
31 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
31 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
34 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
35 <   implies no truncation.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
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 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
40 <   (avoids "Not in Edit Mode" error).
43 > 4. FBMessages: removal of unused messages
44  
45 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
45 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
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 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
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 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
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 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
62 > 4. IColumnMetaData: new method.
63  
64 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
60 <     problem with row size when exception is called.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
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 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
74 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
77 <     keyed in i.e. when autocomplete not performed
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 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
81 <     console mode applications with all LCL required functions (builtin dialogs and
82 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
83 <     not included in your project, IBX should compile and link with a console mode program.
74 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
75 <     console mode application or the IDE will automatically assume that your
76 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
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  
78     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
79     to use the built in dialogs and cursor management. IBDialogs is
80     included by default if "ibexpress" is in your project source's "uses" clause.
81     This should be the case for all projects created through the IDE. This is why
82     you do not want to add the ibexpress package to console mode applications. The
83     ibexpressconsolemode package has been created to allow console mode programs
84     to avoid adding LCL dependencies when using IBX, while still having the
85     unit search paths set up correctly.
85  
87     Existing users should check to ensure that the "ibexpress" unit is included in
88     each project's source file (*.lpr).
86  
87 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
91 <     exists, you have to first open the package in the IDE and then close it. This
92 <     adds it to the most recently accessed packages list. To make it permanently
93 <     available, add the package name to lazarus' staticpackages.inc file.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 <         Thanks to Julio Jiménez for suggesting support of console mode.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 7.   SQL Parser can now accept quoted strings that include new lines
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
95 <     of text on start of edit. This is particularly useful when tabbing to a
96 <     column and then inserting text.
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 < 9.   New Examples provided for IB Services and ISQLMonitor.
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 < 10. Fix error when writing to blob streams that recorded only the last buffer
106 <    write in the blob stream. In most cases, this did not cause a problem as the
107 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
108 <    of a graphic type prefix was lost which caused a problem when the image could
109 <        not be automatically recognised.
101 > 5. New function added to IB.pas
102  
103 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
112 <    already open" errors due to random numbers used for the cursor name being identical.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
106 <    when opening the table and the Primary Key is the last or only column in the
107 <    table. Thanks to Rick Hoover for the fix.
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 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
119 <    of "UTF-8", and update list of available database character sets. Existing
120 <    users should check the current lc_ctype setting in their applications.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +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.  Firebird Services: avoid List Index error when opening a service with an
116 <    empty Params property.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
120 <    Link now set up in Loaded method - avoids occasional failure to apply
121 <    SQL markup on initial open.
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.  "Employees" example performance improvements when scrolling.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
128 <    TFrame. Force recaching of selected frame to avoid GTK race (results in a
129 <    random image cached).
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.  DBControlGrid: Should now react to changes in panel height at run time.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
135 <    even when further rows exist.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
143 <    always be derived from panel height and setting this property can cause confusion.
144 <    Note for existing projects: to avoid a missing property error at run time,
145 <    each form using the DBControlGrid must be opened, updated and saved in the IDE
146 <    in order to remove the property value from the lfm.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 + 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
152 <    call Prepare before setting parameter values.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
154 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
145  
146 < 3.  Code tidyup and more robust handling of dsql information result vector.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 4.  Support for centralised handling of transaction status changes. TIBTransaction
159 <    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
160 <    and "AfterExecQuery". The first three are called after the same event is called
161 <    for an IBCustomDataSet descendent using the Transaction. The fourth is called
162 <    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
163 <    enable monitoring of transaction status changes for a given transaction to be
164 <    handled in a single place. For example, when a change to the dataset occurs
165 <    an indicator can be set that shows the user that in order to save changes,
166 <    the transaction should be committed.  Rather than doing this per dataset, this
167 <    can now be done per transaction.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
151 <    the dataset is scrolled. However, any changes to the current row are, by default,
152 <    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
172 <    have a new property "DataSetCloseAction" that adds automatic posting of changes
173 <    on dataset close. If this property is set to dcDiscardChanges (default) then the
174 <    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
175 <    then IBX will attempt to post any unsaved changes before the dataset is closed
176 <    (and after the BeforeClose event handler is called). The exception is when the
177 <    dataset is being closed as a result of a transaction rollback. In this case,
178 <    no action is taken and any unsaved  changes are discarded. This avoids both
179 <    unnecessary overhead and the risk that a validation error may occur in the Post
180 <    raising an exception and thereby preventing a rollback.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
155 <    In earlier versions, the Display Width was set to the maximum byte width rather than the character
156 <    width. Display Widths are now corrected by dividing by the max byte width per character.
157 <    For UTF8 character sets, the byte width is four and hence the Display Width will be
186 <    the byte width divided by 4. The byte width of each character set is determined
187 <    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
188 <    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
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 < 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 8.  IBLookupComboEditBox: List should now always be restored to full list when the
193 <    control loses focus. Default Key press default interval reduced to 200ms.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
164 <    when dataset rows are less than visible rows.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
170 <    does not exist or DataSet is empty. More responsive on dataset open. New event
200 <    OnRestorePosition. Column sort disabled if no header row.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
173 <    while dataset state is dsInsert. Avoids posting errors.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
176 <    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
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 < 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
211 <    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
212 <    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
213 <    always "posts" the current record regardless or whether or not it may be more appropriate
214 <    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
215 <    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
216 <    as the first action of the "Post" method and allows the handler to convert the Post
217 <    into a Cancel if that is the appropriate action on moving to a different row. This is
218 <    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
219 <    raised here, but it may still be more appropriate to validate a post and signal
220 <    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
183 > 9. IBUtils code tidy up.
184  
185 < 15. On Unix derived systems, the Firebird library name can now be given as a colon
186 <    separated list. Each library name on the list is tried in turn, in left to right
187 <    order with the first found being used as the firebird library. By default, on Linux,
188 <    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
226 <    overidden by the FBLIB environment variable or the OnGetLibraryName function.
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 <    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
229 <    then it will still attempt to access the database via the Firebird Server and will
230 <    require a username and password. If only the pathname is given, then the username
231 <    and password should be omitted and the unix file permissions are used to grant
232 <    access.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
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 < 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
198 <    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
238 <    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
239 <    corresponds to a row of the linked DataSource. Any data aware control on the
240 <    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
201 <   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
244 <   takes place during database access. This may be useful when there are performance issues with
245 <   the change of cursor. Setting the property to false suppresses the change of cursor.
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 < 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
204 <   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
205 <   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
250 <   making all changes permanent immediately rather than when the transaction is explicitly
251 <   committed.
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 < 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
254 <   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

209 < IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < Development version only.
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 < IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
221 <   This is typically used during an "OnBeforeOpen" event handler to manipulate the
222 <   "Where" and "Having" clauses to implement user specified filters of arbitrary
223 <   complexity.
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 < 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
226 <   three new data aware controls dependent on IBX and which make use of the SQL Parser.
227 <   These are:
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 <   - TIBLookupComboEditBox
231 <   - TIBDynamicGrid
273 <   - TIBTreeview
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 <   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
234 <   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
277 <   to revise the available list and restrict it to items that are prefixed by the
278 <   typed text (either case sensitive or case insensitive). Autoinsert allows a
279 <   newly typed entry to be added to the list dataset and included in the available
280 <   list items.
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 <   TIBDynamicGrid is a TDBGrid descendent that provides for:
283 <   - automatic resizing of selected columns to fill the available row length
284 <   - automatic positioning and sizing of a "totals" control, typically at the
285 <     column footer, on a per column basis.
286 <   - DataSet resorting on header row click, sorting the dataset by the selected column.
287 <     A second click on the same header cell reversed the sort order.
288 <   - Support for a "Panel Editor". That is on clicking the indicator column, the row
289 <     is automatically expanded and a panel superimposed on it. The panel can have any
290 <     number of child controls, typically data aware controls with the same datasource
291 <     as the grid allowing for editing of additional fields and more complex editors.
292 <   - Reselection of the same row following resorting.
293 <   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
294 <     Its properties are specified on a per column basis and allows for one or more
295 <     columns to have their values selected from a list provided by a dataset.
296 <     Autocomplete and autoinsert are also available. The existing picklist editor
297 <     is unaffected by the extension.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 <   TIBTreeView is a data aware TCustomTreeView.
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 < 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
302 <   zero scale will no longer return an error. An Int64 will be returned instead.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 4. TIBTransaction now has events for Before and After Transaction End and a new function
305 <   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
308 <   repeated multiple times.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
250 <   check used to get in the way of using Stored Procedures, and "Update or Insert"
251 <   statements.
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 < 7. Insert, Modify and Delete property Editors now support Query Generation from
315 <   Stored Procedures.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 8. Three new examples illustrate the use of the new IB Controls
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 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 +    of const passed to IAttachment.OpenCursor, etc.
261  
320 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
262  
263 < 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
323 <   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
324 <   Gabor Boros for reporting this problem and for testing the improvements).
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
327 <   See readme.field+param.names in the doc folder.
265 > 1. Change syntax to Mode Delphi
266  
267 < 3. IBX SQL Editors will now automatically add double quotes around column names when the database
268 <   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
335 <   actions.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
276 <   thanks to Yuriy Kopnin for pointing this out).
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
343 <   for both fields and parameter setting.
280 > 7. Testsuite updated for Delphi
281  
282 < 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
346 <   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
285 <    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 11. TIBTable now has a property editor for "MasterFields"
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
354 <    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
293 <    of settings is unrecognised. Selecting this radio button has no effect on the settings.
294 <  
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 < IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 1. In a TIBCustomDataset descendent, a generator now only sets the value when
305 <   it is null. This allows for alternative user defined setting of the generator
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 <   Many thanks to Julio Jiménez for this fix
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 < 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
311 <   and suggests that the user may have forgotten to install it.
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.

315  
316 < 1. Conditional compilation used to limit registration of TIntegerField to
377 <   Lazarus versions less than 1.1
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 2. When a database connection is created, character set is now by default set
380 <   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
381 <   1250 to 1254.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.

389 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
390
391 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
392   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
393
394 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
395   package is changed to do this (which it should do).
396
397 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
398
399 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
400
401 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
402
403 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
404
405 4. Property editors should now correctly resize.
406
407 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
408   (restored original functionality)
409
410 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
411   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
