2  
3 < 1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
4 <   include remote system name.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
7 <   tables when data included in output.
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. Profiling: IBSQL now has conditional compilation flags to enable query performance
10 <   and timing information to be written to stdout. This may be used to locate
11 <   performance bottlenecks.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. SQLParser: only call "OnChanging" event handler when value is different.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
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. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
24 <   that BindFields is called when the query is next activated. Avoids FieldName
25 <   not found error.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
21 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
27  
28 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
28 <   hexadecimal notation.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
36 <   using a simple XML format.
35 > 3. New API Calls:
36 >        IColumnMetaData.GetStatement
37 >        IColumnMetaData.GetTransaction
38 >        ISQLData.GetStrLength
39 >        IResults.GetStatement
40 >        IAttachment.OpenBlob (using Blob metadata)
41 >        IAttachment.OpenArray (using array metadata)
42  
43 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
34 <   grants to these objects.
43 > 4. FBMessages: removal of unused messages
44  
45 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
37 <   dependency problems restoring complex databases.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 7. TIBXScript: This component has been restructured to allow for the processing of
40 <   embedded XML in INSERT statements and to support interactive sources in addition
41 <   to non-interactive data sources such as files.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
52 <   SET SQL DIALECT
47 <   SET TERM
48 <   SET AUTODDL
49 <   SET BAIL
50 <   SET ECHO
51 <   SET COUNT
52 <   SET STATS
53 <   SET NAMES <character set>
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 < 10. IBVersion unit added to hold current IBX Version Number information.
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 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
59 <    and domain definitions.
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 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
61 <    fully supported.
62 > 4. IColumnMetaData: new method.
63  
64 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
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 < See also doc/IBX4LazarusGuide.pdf for important information on
74 < upgrading to IBX2.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 1. Size property of TIBStringField is now the width in characters of the field
77 <   and not the byte length. This applies only to multi-byte character sets such
78 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
75 <   code is not recognised as a bug and hence this change to align the behaviour.
76 <   The TStringField change is expected in fpc 3.2.0.
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 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
81 <   true (default) then Size property value saved in the lfm is ignored. Size is
82 <   always set from the dynamic information read from the database. It is unclear
83 <   why anyone would want to override this and set Size to false.
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  
83 3. ibxscript: should now handle correctly a Case..End statement within a procedure
84   block.
85  
86 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
87   exist when an attempt is made to connect to it (run time only) then an attempt
88   is made to create the database.
86  
87 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
91 <   has been successfully created as a result of a call to CreateDatabase or when
92 <   creating a database after it was found not to exist.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 6.  DBControlGrid: a race condition could result in the wrong row image being
95 <    written to the cache. This has been avoided by a trip round the message
96 <    loop before rendering the row image.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
92 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
100 <    known to risk corrupt rendering of row images when the control is first
101 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
102 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
95 <    a TDateEdit control located on an editor panel.
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.  TIBExtract: brought up-to-date plus many bug fixes.
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. DBControlGrid: Removed memory leak when updating rows.
101 > 5. New function added to IB.pas
102  
103 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
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 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
116 <   when target codepage is CP_NONE. This is a workaround for
117 <   http://bugs.freepascal.org/view.php?id=30622.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 2. DBLog option removed from TIBStatisticalService - not supported by server
113 <   since Firebird 1.5.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
116 <   similar.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 4. IBCodePage: updated mapping between codepages and character id.
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 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
125 <   Firebird. Character sets with a char width of two are not UTF16.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 6. Strings received from the database are now always transliterated into UTF8
128 <   regardless of the database character set or connection character set. This
129 <   is for compatibility with the LCL.
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 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
135 <   read in an entire blob just to get the size of the blob. General performance
138 <   improvement when opening datasets containing blobs.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
143 <   is now used.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
146 <   determined.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
150 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
151   lazarus 1.6.0
145  
146 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
154 <   compilation error.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 1. No character set specified for connection: when a text blob is retrieved, the
151 <  character set is determined by looking up the native character set using then
152 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
161 <  set as the connection.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
155 <   for Login Dialog returing a change to the database path.
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. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
167 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
168 <   entered value to be saved on a project specific basis (design time only).
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
171 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
172 <   Otherwise, it sets the column text to the selected ListField Value.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
164 <   column width.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
170 <   and a case insensitive search is requested.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
173 <   or column ListSource.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
176 <   unprepare) when closing and the text has not changed.
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 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
187 <   Less likely to cause a cursor re-use error on Windows.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
190 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
183 > 9. IBUtils code tidy up.
184  
185 < 11. TIBTreeView: Guard against nil destination on record changed
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 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
195 <    string type with the code page set to reflect the returned field encoding after
196 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
197 <    earlier versions.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
193 <    will now result in transliteration to the code page specified for the Firebird driver
194 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
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 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
198 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
205 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
206 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
207 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
208 <    the GETACP is used to determine the Windows code page.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
201 <    name used as the lc_ctype when the database was opened. Only valid while the
212 <    Database is connected.
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 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
204 <    id that corresponds to the DefaultCharSetName.
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

208  
209 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
210 <   path is given and database attach fails due to access permission issues on the
221 <   temp directory or security database, then the attach is retried with "localhost:"
222 <   prefixing the databasename. This should avoid problems when the database has to
223 <   be accessed by a local (e.g. classic) server and libfbembed is used.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 2. Windows: revised search order for Firebird DLL:
213 <     i.   The Firebird Embedded Server in the application Directory.
214 <     ii.  If the FIREBIRD environment variable is set then the directory this
215 <          points to is searched for the FB Client DLL and then then underlying
229 <          "bin" directory.
230 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
231 <          is used to locate the Firebird installation directory and the underlying
232 <          "bin" directory is searched for the FB Client DLL.
233 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
234 <          are searched for the FB Client DLL.
235 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
236 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
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 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
218 <   See doc/readme.scriptengine and example applications.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
221 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
222 <   See dpc/readme.localdatabase and example applications.
220 > 4. Charset ID problem. When using Firebird 3, with no default database 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 < 5. IBDynamicGrid: Reordering on column header click should now also work for
226 <   dynamic columns.
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 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
231 <   between incrementing/decrementing the lock count and signalling the event.
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 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
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 < 1.3.2 was never formally released and only made available as beta copies.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
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 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
262 <   i.e. when it is a calculated field
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
250 <   This problem was due to a race condition between recalculating row heights and
251 <   determining which row was selected by the mouse click. The row height calculation
252 <   is now deferred by an extra trip round the message loop allowing the row to
268 <   be always calculated on the current grid layout rather than risking it being
269 <   calculated on the grid layout after the expanded row has been shrunk.
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 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
272 <   Windows.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
257 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
276 <   to be determined at runtime. See doc/readme.charactersets.html.
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 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
260 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
281 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
282   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
283   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
262  
263 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
286 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
287 <   implies no truncation.

264  
265 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
265 > 1. Change syntax to Mode Delphi
266  
267 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
268 <   (avoids "Not in Edit Mode" error).
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
297 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
280 > 7. Testsuite updated for Delphi
281  
282 < 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 1.   OnCloseUp Event Handler added to TDBLookupProperties
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
312 <     problem with row size when exception is called.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
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 < 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
317 <     in a TCustomComboBox and ignores return key if in a TCustomMemo
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
320 <     keyed in i.e. when autocomplete not performed
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
302 <     console mode applications with all LCL required functions (builtin dialogs and
324 <     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
325 <     not included in your project, IBX should compile and link with a console mode program.
326 <     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
327 <     console mode application or the IDE will automatically assume that your
328 <     application is GUI based. Instead, you should include the ibexpressconsolemode package.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 <     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
305 <     to use the built in dialogs and cursor management. IBDialogs is
332 <     included by default if "ibexpress" is in your project source's "uses" clause.
333 <     This should be the case for all projects created through the IDE. This is why
334 <     you do not want to add the ibexpress package to console mode applications. The
335 <     ibexpressconsolemode package has been created to allow console mode programs
336 <     to avoid adding LCL dependencies when using IBX, while still having the
337 <     unit search paths set up correctly.
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 <     Existing users should check to ensure that the "ibexpress" unit is included in
308 <     each project's source file (*.lpr).
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 <     You may find that in order for the IDE to recognise that ibexpressconsolemode
311 <     exists, you have to first open the package in the IDE and then close it. This
312 <     adds it to the most recently accessed packages list. To make it permanently
345 <     available, add the package name to lazarus' staticpackages.inc file.
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 <         Thanks to Julio Jiménez for suggesting support of console mode.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 7.   SQL Parser can now accept quoted strings that include new lines
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
352 <     of text on start of edit. This is particularly useful when tabbing to a
353 <     column and then inserting text.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.

321  
322 < 10. Fix error when writing to blob streams that recorded only the last buffer
358 <    write in the blob stream. In most cases, this did not cause a problem as the
359 <    IB Blob Stream is written in a single write. However, with the TDBImage, write
360 <    of a graphic type prefix was lost which caused a problem when the image could
361 <        not be automatically recognised.
322 > 1. Initial Release
323  
363 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
364    already open" errors due to random numbers used for the cursor name being identical.
365
366 12. IBTable: corrected error that could result in an "Index out of bounds" error
367    when opening the table and the Primary Key is the last or only column in the
368    table. Thanks to Rick Hoover for the fix.
369
370 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
371    of "UTF-8", and update list of available database character sets. Existing
372    users should check the current lc_ctype setting in their applications.

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

512 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
513
514 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
515   This is typically used during an "OnBeforeOpen" event handler to manipulate the
516   "Where" and "Having" clauses to implement user specified filters of arbitrary
517   complexity.
518
519 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
520   three new data aware controls dependent on IBX and which make use of the SQL Parser.
521   These are:
522
523   - TIBLookupComboEditBox
524   - TIBDynamicGrid
525   - TIBTreeview
526
527   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
528   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
529   to revise the available list and restrict it to items that are prefixed by the
530   typed text (either case sensitive or case insensitive). Autoinsert allows a
531   newly typed entry to be added to the list dataset and included in the available
532   list items.
533
534   TIBDynamicGrid is a TDBGrid descendent that provides for:
535   - automatic resizing of selected columns to fill the available row length
536   - automatic positioning and sizing of a "totals" control, typically at the
537     column footer, on a per column basis.
538   - DataSet resorting on header row click, sorting the dataset by the selected column.
539     A second click on the same header cell reversed the sort order.
540   - Support for a "Panel Editor". That is on clicking the indicator column, the row
541     is automatically expanded and a panel superimposed on it. The panel can have any
542     number of child controls, typically data aware controls with the same datasource
543     as the grid allowing for editing of additional fields and more complex editors.
544   - Reselection of the same row following resorting.
545   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
546     Its properties are specified on a per column basis and allows for one or more
547     columns to have their values selected from a list provided by a dataset.
548     Autocomplete and autoinsert are also available. The existing picklist editor
549     is unaffected by the extension.
550
551   TIBTreeView is a data aware TCustomTreeView.
552
553 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
554   zero scale will no longer return an error. An Int64 will be returned instead.
555
556 4. TIBTransaction now has events for Before and After Transaction End and a new function
557   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
558
559 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
560   repeated multiple times.
561
562 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
563   check used to get in the way of using Stored Procedures, and "Update or Insert"
564   statements.
565
566 7. Insert, Modify and Delete property Editors now support Query Generation from
567   Stored Procedures.
568
569 8. Three new examples illustrate the use of the new IB Controls

573
574 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
575   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
576   Gabor Boros for reporting this problem and for testing the improvements).
577
578 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
579   See readme.field+param.names in the doc folder.
580
581 3. IBX SQL Editors will now automatically add double quotes around column names when the database
582   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
583
584 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
585
586 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
587   actions.
588
589 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
590   thanks to Yuriy Kopnin for pointing this out).
591
592 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
593
594 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
595   for both fields and parameter setting.
596
597 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
598   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
599
600 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
601    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
602
603 11. TIBTable now has a property editor for "MasterFields"
604
605 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
606    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
607
608 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
609    of settings is unrecognised. Selecting this radio button has no effect on the settings.

617
618 1. In a TIBCustomDataset descendent, a generator now only sets the value when
619   it is null. This allows for alternative user defined setting of the generator
620
621   Many thanks to Julio Jiménez for this fix
622
623 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
624   and suggests that the user may have forgotten to install it.
625

627
628 1. Conditional compilation used to limit registration of TIntegerField to
629   Lazarus versions less than 1.1
630
631 2. When a database connection is created, character set is now by default set
632   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
633   1250 to 1254.

641 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
642
643 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
644   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
645
646 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
647   package is changed to do this (which it should do).
648

650
651 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
652
653 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
654
655 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
656
657 4. Property editors should now correctly resize.
658
659 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
660   (restored original functionality)
661
662 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
663   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
