2  
3 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 <   changes.
3 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 >   case sensitive
5  
6 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 <   Bug could result in truncated multi-byte character set values.
6 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7  
8 < 3. Changes consequential on moving fbintf character set utility functions from
9 <   IFirebirdAPI to IAttachment.
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. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
16 > 4. FBMessages: removal of unused messages
17  
18 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 <   results in autocomplete ignoring prefix text.
18 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19  
20 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21  
22 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
20 <   include remote system name.
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
25 <   tables when data included in output.
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 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
28 <   and timing information to be written to stdout. This may be used to locate
29 <   performance bottlenecks.
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 < 4. SQLParser: only call "OnChanging" event handler when value is different.
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 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
35 > 4. IColumnMetaData: new method.
36  
37 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
38 <   that BindFields is called when the query is next activated. Avoids FieldName
39 <   not found error.
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
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 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
50 <   hexadecimal notation.
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 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
54 <   using a simple XML format.
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  
49 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
50   grants to these objects.
58  
52 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
53   dependency problems restoring complex databases.
59  
60 < 7. TIBXScript: This component has been restructured to allow for the processing of
56 <   embedded XML in INSERT statements and to support interactive sources in addition
57 <   to non-interactive data sources such as files.
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
65 <   SET SQL DIALECT
63 <   SET TERM
64 <   SET AUTODDL
65 <   SET BAIL
66 <   SET ECHO
67 <   SET COUNT
68 <   SET STATS
69 <   SET NAMES <character set>
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 10. IBVersion unit added to hold current IBX Version Number information.
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 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
72 <    and domain definitions.
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 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
77 <    fully supported.
74 > 5. New function added to IB.pas
75  
76 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
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 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < See also doc/IBX4LazarusGuide.pdf for important information on
86 < upgrading to IBX2.
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < 1. Size property of TIBStringField is now the width in characters of the field
89 <   and not the byte length. This applies only to multi-byte character sets such
90 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
91 <   code is not recognised as a bug and hence this change to align the behaviour.
92 <   The TStringField change is expected in fpc 3.2.0.
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
93 <   true (default) then Size property value saved in the lfm is ignored. Size is
94 <   always set from the dynamic information read from the database. It is unclear
95 <   why anyone would want to override this and set Size to false.
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 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
98 <   block.
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
101 <   exist when an attempt is made to connect to it (run time only) then an attempt
102 <   is made to create the database.
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 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
105 <   has been successfully created as a result of a call to CreateDatabase or when
108 <   creating a database after it was found not to exist.
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 < 6.  DBControlGrid: a race condition could result in the wrong row image being
108 <    written to the cache. This has been avoided by a trip round the message
112 <    loop before rendering the row image.
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109  
110 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
115 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
116 <    known to risk corrupt rendering of row images when the control is first
117 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
118 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
121 <    a TDateEdit control located on an editor panel.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 10. DBControlGrid: Removed memory leak when updating rows.
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
127 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
118  
119 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
132 <   when target codepage is CP_NONE. This is a workaround for
133 <   http://bugs.freepascal.org/view.php?id=30622.
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 2. DBLog option removed from TIBStatisticalService - not supported by server
124 <   since Firebird 1.5.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
128 <   similar.
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 < 4. IBCodePage: updated mapping between codepages and character id.
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
144 <   Firebird. Character sets with a char width of two are not UTF16.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 6. Strings received from the database are now always transliterated into UTF8
137 <   regardless of the database character set or connection character set. This
138 <   is for compatibility with the LCL.
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144  
145 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
146 <   read in an entire blob just to get the size of the blob. General performance
154 <   improvement when opening datasets containing blobs.
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
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 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
159 <   is now used.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
162 <   determined.
156 > 9. IBUtils code tidy up.
157  
158 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
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 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
167 <   lazarus 1.6.0
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
166 <   compilation error.
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 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < 1. No character set specified for connection: when a text blob is retrieved, the
174 <  character set is determined by looking up the native character set using then
176 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
177 <  set as the connection.
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 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
177 <   for Login Dialog returing a change to the database path.
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 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
183 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
184 <   entered value to be saved on a project specific basis (design time only).
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
183 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
188 <   Otherwise, it sets the column text to the selected ListField Value.
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
186 <   column width.
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 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
191 <   and a case insensitive search is requested.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
194 <   or column ListSource.
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 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
199 <   unprepare) when closing and the text has not changed.
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 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
204 <   Less likely to cause a cursor re-use error on Windows.
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 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
207 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
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 < 11. TIBTreeView: Guard against nil destination on record changed
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
212 <    string type with the code page set to reflect the returned field encoding after
213 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
214 <    earlier versions.
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 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
216 <    will now result in transliteration to the code page specified for the Firebird driver
217 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
220 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
221 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
222 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
223 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
224 <    the GETACP is used to determine the Windows code page.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219  
220 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
227 <    name used as the lc_ctype when the database was opened. Only valid while the
228 <    Database is connected.
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
223 <    id that corresponds to the DefaultCharSetName.
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 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
230 <   path is given and database attach fails due to access permission issues on the
237 <   temp directory or security database, then the attach is retried with "localhost:"
238 <   prefixing the databasename. This should avoid problems when the database has to
239 <   be accessed by a local (e.g. classic) server and libfbembed is used.
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.

232 < 2. Windows: revised search order for Firebird DLL:
233 <     i.   The Firebird Embedded Server in the application Directory.
243 <     ii.  If the FIREBIRD environment variable is set then the directory this
244 <          points to is searched for the FB Client DLL and then then underlying
245 <          "bin" directory.
246 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
247 <          is used to locate the Firebird installation directory and the underlying
248 <          "bin" directory is searched for the FB Client DLL.
249 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
250 <          are searched for the FB Client DLL.
251 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
252 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234  
254 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
255   See doc/readme.scriptengine and example applications.
235  
236 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
258 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
259 <   See dpc/readme.localdatabase and example applications.

237  
238 < 5. IBDynamicGrid: Reordering on column header click should now also work for
262 <   dynamic columns.
238 > 1. Change syntax to Mode Delphi
239  
240 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
241 <   between incrementing/decrementing the lock count and signalling the event.
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.

243 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 < 1.3.2 was never formally released and only made available as beta copies.
246 > 4. Generics syntax variations for Delphi added
247  
248 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
253 > 7. Testsuite updated for Delphi
254  
255 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
278 <   i.e. when it is a calculated field
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
258 <   This problem was due to a race condition between recalculating row heights and
282 <   determining which row was selected by the mouse click. The row height calculation
283 <   is now deferred by an extra trip round the message loop allowing the row to
284 <   be always calculated on the current grid layout rather than risking it being
285 <   calculated on the grid layout after the expanded row has been shrunk.
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
261 <   Windows.
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
291 <   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
292 <   to be determined at runtime. See doc/readme.charactersets.html.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
266 <   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
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 < 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
298 <   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
299 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 <   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
302 <   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
303 <   implies no truncation.
272 > 6. Add ISQL style performance statistics collection to IStatement
273  
274 < 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
278 <   (avoids "Not in Edit Mode" error).
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 < 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
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 < 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
284 <    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
283 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance

286  
287 < 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
287 > 11. API Version information added as constants to IB.pas

295 < IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
295 > 1. Initial Release
296  
325 1.   OnCloseUp Event Handler added to TDBLookupProperties
326
327 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
328     problem with row size when exception is called.
329
330 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
331
332 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
333     in a TCustomComboBox and ignores return key if in a TCustomMemo
334
335 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
336     keyed in i.e. when autocomplete not performed
337
338 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
339     console mode applications with all LCL required functions (builtin dialogs and
340     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
341     not included in your project, IBX should compile and link with a console mode program.
342     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
343     console mode application or the IDE will automatically assume that your
344     application is GUI based. Instead, you should include the ibexpressconsolemode package.
345
346     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
347     to use the built in dialogs and cursor management. IBDialogs is
348     included by default if "ibexpress" is in your project source's "uses" clause.
349     This should be the case for all projects created through the IDE. This is why
350     you do not want to add the ibexpress package to console mode applications. The
351     ibexpressconsolemode package has been created to allow console mode programs
352     to avoid adding LCL dependencies when using IBX, while still having the
353     unit search paths set up correctly.
354
355     Existing users should check to ensure that the "ibexpress" unit is included in
356     each project's source file (*.lpr).
357
358     You may find that in order for the IDE to recognise that ibexpressconsolemode
359     exists, you have to first open the package in the IDE and then close it. This
360     adds it to the most recently accessed packages list. To make it permanently
361     available, add the package name to lazarus' staticpackages.inc file.
362
363         Thanks to Julio Jiménez for suggesting support of console mode.
364
365 7.   SQL Parser can now accept quoted strings that include new lines
366
367 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
368     of text on start of edit. This is particularly useful when tabbing to a
369     column and then inserting text.
370
371 9.   New Examples provided for IB Services and ISQLMonitor.
372
373 10. Fix error when writing to blob streams that recorded only the last buffer
374    write in the blob stream. In most cases, this did not cause a problem as the
375    IB Blob Stream is written in a single write. However, with the TDBImage, write
376    of a graphic type prefix was lost which caused a problem when the image could
377        not be automatically recognised.
378
379 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
380    already open" errors due to random numbers used for the cursor name being identical.
381
382 12. IBTable: corrected error that could result in an "Index out of bounds" error
383    when opening the table and the Primary Key is the last or only column in the
384    table. Thanks to Rick Hoover for the fix.
385
386 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
387    of "UTF-8", and update list of available database character sets. Existing
388    users should check the current lc_ctype setting in their applications.
389
390 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
391
392 1.  Firebird Services: avoid List Index error when opening a service with an
393    empty Params property.
394
395 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
396    Link now set up in Loaded method - avoids occasional failure to apply
397    SQL markup on initial open.
398
399 3.  "Employees" example performance improvements when scrolling.
400
401 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
402    TFrame. Force recaching of selected frame to avoid GTK race (results in a
403    random image cached).
404
405 5.  DBControlGrid: Should now react to changes in panel height at run time.
406
407 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
408    even when further rows exist.
409
410 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
411    always be derived from panel height and setting this property can cause confusion.
412    Note for existing projects: to avoid a missing property error at run time,
413    each form using the DBControlGrid must be opened, updated and saved in the IDE
414    in order to remove the property value from the lfm.
415
416
417 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
418
419 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
420    call Prepare before setting parameter values.
421
422 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
423
424 3.  Code tidyup and more robust handling of dsql information result vector.
425
426 4.  Support for centralised handling of transaction status changes. TIBTransaction
427    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
428    and "AfterExecQuery". The first three are called after the same event is called
429    for an IBCustomDataSet descendent using the Transaction. The fourth is called
430    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
431    enable monitoring of transaction status changes for a given transaction to be
432    handled in a single place. For example, when a change to the dataset occurs
433    an indicator can be set that shows the user that in order to save changes,
434    the transaction should be committed.  Rather than doing this per dataset, this
435    can now be done per transaction.
436
437 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
438    the dataset is scrolled. However, any changes to the current row are, by default,
439    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
440    have a new property "DataSetCloseAction" that adds automatic posting of changes
441    on dataset close. If this property is set to dcDiscardChanges (default) then the
442    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
443    then IBX will attempt to post any unsaved changes before the dataset is closed
444    (and after the BeforeClose event handler is called). The exception is when the
445    dataset is being closed as a result of a transaction rollback. In this case,
446    no action is taken and any unsaved  changes are discarded. This avoids both
447    unnecessary overhead and the risk that a validation error may occur in the Post
448    raising an exception and thereby preventing a rollback.
449
450 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
451    In earlier versions, the Display Width was set to the maximum byte width rather than the character
452    width. Display Widths are now corrected by dividing by the max byte width per character.
453    For UTF8 character sets, the byte width is four and hence the Display Width will be
454    the byte width divided by 4. The byte width of each character set is determined
455    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
456    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
457
458 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
459
460 8.  IBLookupComboEditBox: List should now always be restored to full list when the
461    control loses focus. Default Key press default interval reduced to 200ms.
462
463 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
464    when dataset rows are less than visible rows.
465
466 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
467    does not exist or DataSet is empty. More responsive on dataset open. New event
468    OnRestorePosition. Column sort disabled if no header row.
469
470 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
471    while dataset state is dsInsert. Avoids posting errors.
472
473 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
474    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
475
476 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
477
478 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
479    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
480    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
481    always "posts" the current record regardless or whether or not it may be more appropriate
482    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
483    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
484    as the first action of the "Post" method and allows the handler to convert the Post
485    into a Cancel if that is the appropriate action on moving to a different row. This is
486    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
487    raised here, but it may still be more appropriate to validate a post and signal
488    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
489
490 15. On Unix derived systems, the Firebird library name can now be given as a colon
491    separated list. Each library name on the list is tried in turn, in left to right
492    order with the first found being used as the firebird library. By default, on Linux,
493    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
494    overidden by the FBLIB environment variable or the OnGetLibraryName function.
495
496    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
497    then it will still attempt to access the database via the Firebird Server and will
498    require a username and password. If only the pathname is given, then the username
499    and password should be omitted and the unix file permissions are used to grant
500    access.
501
502 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
503
504 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
505    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
506    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
507    corresponds to a row of the linked DataSource. Any data aware control on the
508    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
509
510 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
511   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
512   takes place during database access. This may be useful when there are performance issues with
513   the change of cursor. Setting the property to false suppresses the change of cursor.
514
515 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
516   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
517   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
518   making all changes permanent immediately rather than when the transaction is explicitly
519   committed.
520
521 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
522   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

527
528 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
529
530 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
531   This is typically used during an "OnBeforeOpen" event handler to manipulate the
532   "Where" and "Having" clauses to implement user specified filters of arbitrary
533   complexity.
534
535 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
536   three new data aware controls dependent on IBX and which make use of the SQL Parser.
537   These are:
538
539   - TIBLookupComboEditBox
540   - TIBDynamicGrid
541   - TIBTreeview
542
543   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
544   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
545   to revise the available list and restrict it to items that are prefixed by the
546   typed text (either case sensitive or case insensitive). Autoinsert allows a
547   newly typed entry to be added to the list dataset and included in the available
548   list items.
549
550   TIBDynamicGrid is a TDBGrid descendent that provides for:
551   - automatic resizing of selected columns to fill the available row length
552   - automatic positioning and sizing of a "totals" control, typically at the
553     column footer, on a per column basis.
554   - DataSet resorting on header row click, sorting the dataset by the selected column.
555     A second click on the same header cell reversed the sort order.
556   - Support for a "Panel Editor". That is on clicking the indicator column, the row
557     is automatically expanded and a panel superimposed on it. The panel can have any
558     number of child controls, typically data aware controls with the same datasource
559     as the grid allowing for editing of additional fields and more complex editors.
560   - Reselection of the same row following resorting.
561   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
562     Its properties are specified on a per column basis and allows for one or more
563     columns to have their values selected from a list provided by a dataset.
564     Autocomplete and autoinsert are also available. The existing picklist editor
565     is unaffected by the extension.
566
567   TIBTreeView is a data aware TCustomTreeView.
568
569 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
570   zero scale will no longer return an error. An Int64 will be returned instead.
571
572 4. TIBTransaction now has events for Before and After Transaction End and a new function
573   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
574
575 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
576   repeated multiple times.
577
578 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
579   check used to get in the way of using Stored Procedures, and "Update or Insert"
580   statements.
581
582 7. Insert, Modify and Delete property Editors now support Query Generation from
583   Stored Procedures.
584
585 8. Three new examples illustrate the use of the new IB Controls
586
587
588 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
589
590 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
591   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
592   Gabor Boros for reporting this problem and for testing the improvements).
593
594 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
595   See readme.field+param.names in the doc folder.
596
597 3. IBX SQL Editors will now automatically add double quotes around column names when the database
598   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
599
600 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
601
602 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
603   actions.
604
605 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
606   thanks to Yuriy Kopnin for pointing this out).
607
608 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
609
610 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
611   for both fields and parameter setting.
612
613 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
614   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
615
616 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
617    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
618
619 11. TIBTable now has a property editor for "MasterFields"
620
621 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
622    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
623
624 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
625    of settings is unrecognised. Selecting this radio button has no effect on the settings.

634 1. In a TIBCustomDataset descendent, a generator now only sets the value when
635   it is null. This allows for alternative user defined setting of the generator
636
637   Many thanks to Julio Jiménez for this fix
638
639 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
640   and suggests that the user may have forgotten to install it.

644 1. Conditional compilation used to limit registration of TIntegerField to
645   Lazarus versions less than 1.1
646
647 2. When a database connection is created, character set is now by default set

658
659 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
660   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
661
662 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
663   package is changed to do this (which it should do).
664

667 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
668
669 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
670
671 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
672
673 4. Property editors should now correctly resize.
674
675 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
676   (restored original functionality)

678 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
679   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
