1 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +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. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 >   case sensitive
5  
6 < 2. Windows: revised search order for Firebird DLL:
10 <     i.   The Firebird Embedded Server in the application Directory.
11 <     ii.  If the FIREBIRD environment variable is set then the directory this
12 <          points to is searched for the FB Client DLL and then then underlying
13 <          "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. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7  
8 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
9 <   See doc/readme.scriptengine and example applications.
8 > 3. New API Calls:
9 >        IColumnMetaData.GetStatement
10 >        IColumnMetaData.GetTransaction
11 >        ISQLData.GetStrLength
12 >        IResults.GetStatement
13 >        IAttachment.OpenBlob (using Blob metadata)
14 >        IAttachment.OpenArray (using array metadata)
15  
16 < 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.
16 > 4. FBMessages: removal of unused messages
17  
18 < 5. IBDynamicGrid: Reordering on column header click should now also work for
30 <   dynamic columns.
18 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19  
20 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
33 <   between incrementing/decrementing the lock count and signalling the event.
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21  
22 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 1.3.2 was never formally released and only made available as beta copies.
24 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 >   where the second character of the parameter name is a numeric.
26  
27 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
27 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 >   This returns the isc_version connection information as one or more lines.
29 >   This is the same information as returned by isql with the -z option.
30  
31 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
31 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 >   compiler option then the Firebird 3 API is no longer compiled in.
34  
35 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
35 > 4. IColumnMetaData: new method.
36  
37 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
38 <   i.e. when it is a calculated field
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < 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.
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
44 <   Windows.
43 >   This returns the max. number of characters returned by the "AsString" method
44 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45  
46 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
47 <   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.
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
50 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
49 >   If this argument is set to true then SQL parameter names are assumed to be case
50 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
51 >   sensitive name.
52  
53 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
54 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
55 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
53 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
56 >   using .AsString.
57  
69   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
70   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
71   implies no truncation.
58  
73 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
59  
60 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
76 <   (avoids "Not in Edit Mode" error).
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
65 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
67 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
69 >   and processing internal parameters as statement parameters.
70  
71 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
71 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73  
74 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
74 > 5. New function added to IB.pas
75  
76 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
78 >   This allows a Firebird Library to be loaded from an explicit path. use the
79 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 >   the library. It is possible to load Firebird libraries from different locations
81 >   simultaneously, each with a distinct IFirebirdAPI.
82  
83 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
86 <     problem with row size when exception is called.
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
93 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
92 > 3. IServiceManager improved error handling. Interfaces changed:
93 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96  
97 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
98 <     keyed in i.e. when autocomplete not performed
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
101 <     console mode applications with all LCL required functions (builtin dialogs and
102 <     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.
100 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 >   thus now returns accumulated stats for a select statement from opening a cursor
102 >   up to the last fetch.
103  
104 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
105 <     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.
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 <     Existing users should check to ensure that the "ibexpress" unit is included in
108 <     each project's source file (*.lpr).
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
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 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 <         Thanks to Julio Jiménez for suggesting support of console mode.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 7.   SQL Parser can now accept quoted strings that include new lines
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
136 <     of text on start of edit. This is particularly useful when tabbing to a
137 <     column and then inserting text.
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
139 9.   New Examples provided for IB Services and ISQLMonitor.
118  
119 < 10. Fix error when writing to blob streams that recorded only the last buffer
142 <    write in the blob stream. In most cases, this did not cause a problem as the
143 <    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.
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
148 <    already open" errors due to random numbers used for the cursor name being identical.
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 12. IBTable: corrected error that could result in an "Index out of bounds" error
124 <    when opening the table and the Primary Key is the last or only column in the
125 <    table. Thanks to Rick Hoover for the fix.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
128 <    of "UTF-8", and update list of available database character sets. Existing
129 <    users should check the current lc_ctype setting in their applications.
127 >   These return, respectively, true if a connection default character set was
128 >   specified and the character set id of the connection default character set.
129 >   The DefaultCharSetID is cached when the connection is opened and hence does not
130 >   require a database lookup.
131  
132 < IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < 1.  Firebird Services: avoid List Index error when opening a service with an
161 <    empty Params property.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
137 <    Link now set up in Loaded method - avoids occasional failure to apply
138 <    SQL markup on initial open.
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < 3.  "Employees" example performance improvements when scrolling.
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144  
145 < 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
146 <    TFrame. Force recaching of selected frame to avoid GTK race (results in a
171 <    random image cached).
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 < 5.  DBControlGrid: Should now react to changes in panel height at run time.
148 > 7. IAttachment: Create Database using SQL statement. The username and password
149 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 >   It is now possible to use IAttachment disconnect/connect to reconnect to
151 >   a database for which the initial connection was established by a create
152 >   database sql statement. Available in FPC only.
153  
154 < 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
176 <    even when further rows exist.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
179 <    always be derived from panel height and setting this property can cause confusion.
180 <    Note for existing projects: to avoid a missing property error at run time,
181 <    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.
156 > 9. IBUtils code tidy up.
157  
158 + 10. Parameter Block interfaces "find" method. As documented, this should have
159 +   returned a nil interface when the item could not be found. Instead, an empty
160 +   interface item was returned. "Find" now works as documented and will return
161 +   a nil interface if the item cannot be found.
162  
163 < IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
166 <    call Prepare before setting parameter values.
165 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 >    requests with additional parameters. This is to enable support for fb_info_page_contents
167 >    (return of page contents). Response to fb_info_page_contents returned as
168 >    a string with code page CP_NONE.
169  
170 < 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < 3.  Code tidyup and more robust handling of dsql information result vector.
173 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175  
176 < 4.  Support for centralised handling of transaction status changes. TIBTransaction
177 <    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
178 <    and "AfterExecQuery". The first three are called after the same event is called
197 <    for an IBCustomDataSet descendent using the Transaction. The fourth is called
198 <    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.
176 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 >    default connection port to be specified.
179  
180 < 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.
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
183 <    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).
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
185 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 >   not in locale format but which are recognised by Firebird. Date values that
187 >   cannot be converted to a string using Pascal library are now passed through
188 >   to Firebird as Text Strings.
189  
190 < 8.  IBLookupComboEditBox: List should now always be restored to full list when the
191 <    control loses focus. Default Key press default interval reduced to 200ms.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
194 <    when dataset rows are less than visible rows.
193 > 4. Charset ID problem. When using Firebird 3, with no default database character set
194 >   and a column has a non-default collation specified, an incorrect character set
195 >   id was being reported that could result in a 'division by zero' error when
196 >   used by IBX. This has now been fixed.
197  
198 < 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
199 <    does not exist or DataSet is empty. More responsive on dataset open. New event
200 <    OnRestorePosition. Column sort disabled if no header row.
198 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 >   the character sets supported can be updated on a per database basis. That is
201 >   it is possible to add a (Firebird) user defined character set to a database.
202  
203 < 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
204 <    while dataset state is dsInsert. Avoids posting errors.
203 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 >   set supported by Firebird with the API.
205  
206 < 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
207 <    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
206 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 >   in FBOutputBlock.pas and update test suite to include this item.
208  
209 < 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
212 <    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
213 <    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
214 <    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)
211 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 >   library or finding it by disk location, the PATH environment variable is now also set to
213 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 >   firebird client library dependencies are loaded.
215  
216 < 15. On Unix derived systems, the Firebird library name can now be given as a colon
259 <    separated list. Each library name on the list is tried in turn, in left to right
260 <    order with the first found being used as the firebird library. By default, on Linux,
261 <    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.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 <    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
265 <    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.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.

220 < IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
223 <    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
224 <    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
225 <    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.
222 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 >    have been given a value (including NULL). Previously, failing to set the
224 >    value of an SQL Parameter could give rise to unpredictable results or
225 >    an SQLDA error.
226  
227 < 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
279 <   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.
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
230 <   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.
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
231  
232 < 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
233 <   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.

238 < IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
238 > 1. Change syntax to Mode Delphi
239  
240 < 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
241 <   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.
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.
242  
243 < 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
244 <   three new data aware controls dependent on IBX and which make use of the SQL Parser.
305 <   These are:
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 <   - TIBLookupComboEditBox
308 <   - TIBDynamicGrid
309 <   - TIBTreeview
246 > 4. Generics syntax variations for Delphi added
247  
248 <   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
249 <   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.
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 <   TIBDynamicGrid is a TDBGrid descendent that provides for:
319 <   - 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.
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 <   TIBTreeView is a data aware TCustomTreeView.
253 > 7. Testsuite updated for Delphi
254  
255 < 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.
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257 < 4. TIBTransaction now has events for Before and After Transaction End and a new function
258 <   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
261 <   repeated multiple times.
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
347 <   check used to get in the way of using Stored Procedures, and "Update or Insert"
348 <   statements.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 7. Insert, Modify and Delete property Editors now support Query Generation from
266 <   Stored Procedures.
265 > 4. Array Handling: fix problem with text arrays with character set none. When the
266 >   DB connection has a default character set (e.g. UTF8), an error is raised by
267 >   Firebird if the space allocated is not enough to allow for transliteration, even
268 >   though it is not required for character set none.
269  
270 < 8. Three new examples illustrate the use of the new IB Controls
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 + 6. Add ISQL style performance statistics collection to IStatement
273  
274 < IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
278 <   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).
277 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 >   an array dimension is not mistaken for a named parameter prefix.
279  
280 < 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
281 <   See readme.field+param.names in the doc folder.
280 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
281 >   when Character set is octets. Avoids loss of non printable characters at start of string.
282  
283 < 3. IBX SQL Editors will now automatically add double quotes around column names when the database
284 <   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
283 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
284 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 >    to enable stats gathering.
286  
287 < 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
287 > 11. API Version information added as constants to IB.pas
288  
289 < 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
371 <   actions.
289 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290  
291 < 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
374 <   thanks to Yuriy Kopnin for pointing this out).
291 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292  
293 < 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
293 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
294  
295 < 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
379 <   for both fields and parameter setting.
295 > 1. Initial Release
296  
381 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
382   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
383
384 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
385    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
386
387 11. TIBTable now has a property editor for "MasterFields"
388
389 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.
391
392 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.

401
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.

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.
