1 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 <   changes.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
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. 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. Changes consequential on moving fbintf character set utility functions from
10 <   IFirebirdAPI to IAttachment.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
17 <   results in autocomplete ignoring prefix text.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
24 <   entering a new name into the text box.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
20 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21   Firebird rather than recomputing it.
27  
28 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
24 <   screen centre. Previously some were "poDesigned" which may be inappropriate
25 <   for multi monitor desktops.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
30 <    a transaction and always reset the object.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
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 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
43 > 4. FBMessages: removal of unused messages
44  
45 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
37 <    to a gbak format archive.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 16. IBLocaldb: Drop database if error creating an empty database.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
52 <    unless selected node not in current dataset.
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 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
55 <    to TIBCustomService, and IBlocalDB code tidy up.
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 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
59 <    behaviour due to uninitialised variable.
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 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
53 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
62 > 4. IColumnMetaData: new method.
63  
64 < 21. IBSQL: When Database changed ensure that all resources are freed.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
71 <    * Line Wrap on SQL Token boundaries (on user command)
61 <    * auto-complete table names in drop down list of table names
62 <    * Double click on tablename or field name adds to SQL text
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 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
77 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
78 <    workaround for a problem in fpc 3.0.4 win64).
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 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
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  
72 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
85  
74 IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
86  
87 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
77 <   include remote system name.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
80 <   tables when data included in output.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
92 <   and timing information to be written to stdout. This may be used to locate
84 <   performance bottlenecks.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 4. SQLParser: only call "OnChanging" event handler when value is different.
94 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 >   and processing internal parameters as statement parameters.
97  
98 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
91 <   that BindFields is called when the query is next activated. Avoids FieldName
92 <   not found error.
101 > 5. New function added to IB.pas
102  
103 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
95 <   purpose and allows the programmer to define any action they want for Update, Insert
96 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
97 <   filtering of updates, or use of statements such as Grant or Revoke instead of
98 <   normal DML. See User Manual for more information.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
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. TIBEvents: Fix uninitialised variable that could result in lost events.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
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. TIBExtract: data formatted as Charset set "octets" is now output using
116 <   hexadecimal notation.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
120 <   using a simple XML format.
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. TIBExtract: extract of individual Triggers and Stored Procedures can now include
125 <   grants to these objects.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
128 <   dependency problems restoring complex databases.
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 < 7. TIBXScript: This component has been restructured to allow for the processing of
132 <   embedded XML in INSERT statements and to support interactive sources in addition
120 <   to non-interactive data sources such as files.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
125 <   SET SQL DIALECT
126 <   SET TERM
127 <   SET AUTODDL
128 <   SET BAIL
129 <   SET ECHO
130 <   SET COUNT
131 <   SET STATS
132 <   SET NAMES <character set>
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 10. IBVersion unit added to hold current IBX Version Number information.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
137 <    and domain definitions.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
140 <    fully supported.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
142 13. TIBExtract: when a database dump includes data, the generator values are now also set.
145  
146 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < See also doc/IBX4LazarusGuide.pdf for important information on
151 < upgrading to IBX2.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 1. Size property of TIBStringField is now the width in characters of the field
155 <   and not the byte length. This applies only to multi-byte character sets such
156 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
157 <   code is not recognised as a bug and hence this change to align the behaviour.
155 <   The TStringField change is expected in fpc 3.2.0.
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 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
158 <   true (default) then Size property value saved in the lfm is ignored. Size is
159 <   always set from the dynamic information read from the database. It is unclear
160 <   why anyone would want to override this and set Size to false.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
163 <   block.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
164 <   exist when an attempt is made to connect to it (run time only) then an attempt
165 <   is made to create the database.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
170 <   has been successfully created as a result of a call to CreateDatabase or when
171 <   creating a database after it was found not to exist.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 6.  DBControlGrid: a race condition could result in the wrong row image being
173 <    written to the cache. This has been avoided by a trip round the message
175 <    loop before rendering the row image.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
176 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
177 <    known to risk corrupt rendering of row images when the control is first
178 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
179 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
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 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
184 <    a TDateEdit control located on an editor panel.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 9.  TIBExtract: brought up-to-date plus many bug fixes.
183 > 9. IBUtils code tidy up.
184  
185 < 10. DBControlGrid: Removed memory leak when updating rows.
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 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
192 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 >    requests with additional parameters. This is to enable support for fb_info_page_contents
194 >    (return of page contents). Response to fb_info_page_contents returned as
195 >    a string with code page CP_NONE.
196  
197 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
198 <   when target codepage is CP_NONE. This is a workaround for
196 <   http://bugs.freepascal.org/view.php?id=30622.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 2. DBLog option removed from TIBStatisticalService - not supported by server
201 <   since Firebird 1.5.
200 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202  
203 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
204 <   similar.
203 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 >    default connection port to be specified.
206  
207 < 4. IBCodePage: updated mapping between codepages and character id.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
210 <   Firebird. Character sets with a char width of two are not UTF16.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 6. Strings received from the database are now always transliterated into UTF8
213 <   regardless of the database character set or connection character set. This
214 <   is for compatibility with the LCL.
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 >   not in locale format but which are recognised by Firebird. Date values that
214 >   cannot be converted to a string using Pascal library are now passed through
215 >   to Firebird as Text Strings.
216  
217 < IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
221 <   read in an entire blob just to get the size of the blob. General performance
222 <   improvement when opening datasets containing blobs.
220 > 4. Charset ID problem. When using Firebird 3, with no default database character set
221 >   and a column has a non-default collation specified, an incorrect character set
222 >   id was being reported that could result in a 'division by zero' error when
223 >   used by IBX. This has now been fixed.
224  
225 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
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 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
231 <   is now used.
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 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
234 <   determined.
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 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
239 <   lazarus 1.6.0
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 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
233 <   compilation error.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.

245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 1. No character set specified for connection: when a text blob is retrieved, the
238 <  character set is determined by looking up the native character set using then
239 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
240 <  set as the connection.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
250 <   for Login Dialog returing a change to the database path.
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 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
246 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
247 <   entered value to be saved on a project specific basis (design time only).
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
257 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
251 <   Otherwise, it sets the column text to the selected ListField Value.
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 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
260 <   column width.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
256 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
257   and a case insensitive search is requested.
262  
263 < 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
260 <   or column ListSource.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
263 <   unprepare) when closing and the text has not changed.
265 > 1. Change syntax to Mode Delphi
266  
267 < 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
268 <   Less likely to cause a cursor re-use error on Windows.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
271 <   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 11. TIBTreeView: Guard against nil destination on record changed
273 > 4. Generics syntax variations for Delphi added
274  
275 < 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
276 <    string type with the code page set to reflect the returned field encoding after
275 <    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
276 <    earlier versions.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
279 <    will now result in transliteration to the code page specified for the Firebird driver
280 <    if the assigned string has a different code page. FPC 3.0.0 onwards only.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
283 <    is ignored and the lc_ctype value, when the database is opened, is set to align with
284 <    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
285 <    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
286 <    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
287 <    the GETACP is used to determine the Windows code page.
280 > 7. Testsuite updated for Delphi
281  
282 < 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
290 <    name used as the lc_ctype when the database was opened. Only valid while the
291 <    Database is connected.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
285 <    id that corresponds to the DefaultCharSetName.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
299 <   path is given and database attach fails due to access permission issues on the
300 <   temp directory or security database, then the attach is retried with "localhost:"
301 <   prefixing the databasename. This should avoid problems when the database has to
302 <   be accessed by a local (e.g. classic) server and libfbembed is used.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 2. Windows: revised search order for Firebird DLL:
293 <     i.   The Firebird Embedded Server in the application Directory.
294 <     ii.  If the FIREBIRD environment variable is set then the directory this
295 <          points to is searched for the FB Client DLL and then then underlying
308 <          "bin" directory.
309 <     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
310 <          is used to locate the Firebird installation directory and the underlying
311 <          "bin" directory is searched for the FB Client DLL.
312 <     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
313 <          are searched for the FB Client DLL.
314 <     v.   The PATH Environment variable is used to search for the FB Client DLL.
315 <     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
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 < 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
318 <   See doc/readme.scriptengine and example applications.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
321 <   simplify the use of the embedded firebird server on both Linux and Windows platforms.
322 <   See dpc/readme.localdatabase and example applications.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 5. IBDynamicGrid: Reordering on column header click should now also work for
302 <   dynamic columns.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
305 <   between incrementing/decrementing the lock count and signalling the event.
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 < IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
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 < 1.3.2 was never formally released and only made available as beta copies.
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 < 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
314 > 11. API Version information added as constants to IB.pas
315  
316 < 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
341 <   i.e. when it is a calculated field
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
344 <   This problem was due to a race condition between recalculating row heights and
345 <   determining which row was selected by the mouse click. The row height calculation
346 <   is now deferred by an extra trip round the message loop allowing the row to
347 <   be always calculated on the current grid layout rather than risking it being
348 <   calculated on the grid layout after the expanded row has been shrunk.
322 > 1. Initial Release
323  
350 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
351   Windows.
352
353 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
354   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
355   to be determined at runtime. See doc/readme.charactersets.html.
356
357 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
358   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
359
360 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
361   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
362   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
363
364   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
365   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
366   implies no truncation.
367
368 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
369
370 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
371   (avoids "Not in Edit Mode" error).
372
373 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
374
375 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
376    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
377
378 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
379
380 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
381
382 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
383
384 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
385
386 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
387
388 1.   OnCloseUp Event Handler added to TDBLookupProperties
389
390 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
391     problem with row size when exception is called.
392
393 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
394
395 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
396     in a TCustomComboBox and ignores return key if in a TCustomMemo
397
398 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
399     keyed in i.e. when autocomplete not performed
400
401 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
402     console mode applications with all LCL required functions (builtin dialogs and
403     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
404     not included in your project, IBX should compile and link with a console mode program.
405     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
406     console mode application or the IDE will automatically assume that your
407     application is GUI based. Instead, you should include the ibexpressconsolemode package.
408
409     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
410     to use the built in dialogs and cursor management. IBDialogs is
411     included by default if "ibexpress" is in your project source's "uses" clause.
412     This should be the case for all projects created through the IDE. This is why
413     you do not want to add the ibexpress package to console mode applications. The
414     ibexpressconsolemode package has been created to allow console mode programs
415     to avoid adding LCL dependencies when using IBX, while still having the
416     unit search paths set up correctly.
417
418     Existing users should check to ensure that the "ibexpress" unit is included in
419     each project's source file (*.lpr).
420
421     You may find that in order for the IDE to recognise that ibexpressconsolemode
422     exists, you have to first open the package in the IDE and then close it. This
423     adds it to the most recently accessed packages list. To make it permanently
424     available, add the package name to lazarus' staticpackages.inc file.
425
426         Thanks to Julio Jiménez for suggesting support of console mode.
427
428 7.   SQL Parser can now accept quoted strings that include new lines
429
430 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
431     of text on start of edit. This is particularly useful when tabbing to a
432     column and then inserting text.
433
434 9.   New Examples provided for IB Services and ISQLMonitor.
435
436 10. Fix error when writing to blob streams that recorded only the last buffer
437    write in the blob stream. In most cases, this did not cause a problem as the
438    IB Blob Stream is written in a single write. However, with the TDBImage, write
439    of a graphic type prefix was lost which caused a problem when the image could
440        not be automatically recognised.
441
442 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
443    already open" errors due to random numbers used for the cursor name being identical.
444
445 12. IBTable: corrected error that could result in an "Index out of bounds" error
446    when opening the table and the Primary Key is the last or only column in the
447    table. Thanks to Rick Hoover for the fix.
448
449 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
450    of "UTF-8", and update list of available database character sets. Existing
451    users should check the current lc_ctype setting in their applications.
452
453 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
454
455 1.  Firebird Services: avoid List Index error when opening a service with an
456    empty Params property.
457
458 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
459    Link now set up in Loaded method - avoids occasional failure to apply
460    SQL markup on initial open.
461
462 3.  "Employees" example performance improvements when scrolling.
463
464 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
465    TFrame. Force recaching of selected frame to avoid GTK race (results in a
466    random image cached).
467
468 5.  DBControlGrid: Should now react to changes in panel height at run time.
469
470 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
471    even when further rows exist.
472
473 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
474    always be derived from panel height and setting this property can cause confusion.
475    Note for existing projects: to avoid a missing property error at run time,
476    each form using the DBControlGrid must be opened, updated and saved in the IDE
477    in order to remove the property value from the lfm.
478
479
480 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
481
482 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
483    call Prepare before setting parameter values.
484
485 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
486
487 3.  Code tidyup and more robust handling of dsql information result vector.
488
489 4.  Support for centralised handling of transaction status changes. TIBTransaction
490    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
491    and "AfterExecQuery". The first three are called after the same event is called
492    for an IBCustomDataSet descendent using the Transaction. The fourth is called
493    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
494    enable monitoring of transaction status changes for a given transaction to be
495    handled in a single place. For example, when a change to the dataset occurs
496    an indicator can be set that shows the user that in order to save changes,
497    the transaction should be committed.  Rather than doing this per dataset, this
498    can now be done per transaction.
499
500 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
501    the dataset is scrolled. However, any changes to the current row are, by default,
502    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
503    have a new property "DataSetCloseAction" that adds automatic posting of changes
504    on dataset close. If this property is set to dcDiscardChanges (default) then the
505    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
506    then IBX will attempt to post any unsaved changes before the dataset is closed
507    (and after the BeforeClose event handler is called). The exception is when the
508    dataset is being closed as a result of a transaction rollback. In this case,
509    no action is taken and any unsaved  changes are discarded. This avoids both
510    unnecessary overhead and the risk that a validation error may occur in the Post
511    raising an exception and thereby preventing a rollback.
512
513 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
514    In earlier versions, the Display Width was set to the maximum byte width rather than the character
515    width. Display Widths are now corrected by dividing by the max byte width per character.
516    For UTF8 character sets, the byte width is four and hence the Display Width will be
517    the byte width divided by 4. The byte width of each character set is determined
518    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
519    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
520
521 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
522
523 8.  IBLookupComboEditBox: List should now always be restored to full list when the
524    control loses focus. Default Key press default interval reduced to 200ms.
525
526 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
527    when dataset rows are less than visible rows.
528
529 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
530    does not exist or DataSet is empty. More responsive on dataset open. New event
531    OnRestorePosition. Column sort disabled if no header row.
532
533 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
534    while dataset state is dsInsert. Avoids posting errors.
535
536 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
537    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
538
539 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
540
541 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
542    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
543    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
544    always "posts" the current record regardless or whether or not it may be more appropriate
545    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
546    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
547    as the first action of the "Post" method and allows the handler to convert the Post
548    into a Cancel if that is the appropriate action on moving to a different row. This is
549    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
550    raised here, but it may still be more appropriate to validate a post and signal
551    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
552
553 15. On Unix derived systems, the Firebird library name can now be given as a colon
554    separated list. Each library name on the list is tried in turn, in left to right
555    order with the first found being used as the firebird library. By default, on Linux,
556    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
557    overidden by the FBLIB environment variable or the OnGetLibraryName function.
558
559    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
560    then it will still attempt to access the database via the Firebird Server and will
561    require a username and password. If only the pathname is given, then the username
562    and password should be omitted and the unix file permissions are used to grant
563    access.
564
565 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
566
567 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
568    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
569    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
570    corresponds to a row of the linked DataSource. Any data aware control on the
571    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
572
573 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
574   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
575   takes place during database access. This may be useful when there are performance issues with
576   the change of cursor. Setting the property to false suppresses the change of cursor.

578 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
579   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
580   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
581   making all changes permanent immediately rather than when the transaction is explicitly
582   committed.
583
584 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
585   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

591 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
592
593 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
594   This is typically used during an "OnBeforeOpen" event handler to manipulate the
595   "Where" and "Having" clauses to implement user specified filters of arbitrary
596   complexity.
597
598 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
599   three new data aware controls dependent on IBX and which make use of the SQL Parser.
600   These are:
601
602   - TIBLookupComboEditBox
603   - TIBDynamicGrid
604   - TIBTreeview
605
606   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
607   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
608   to revise the available list and restrict it to items that are prefixed by the
609   typed text (either case sensitive or case insensitive). Autoinsert allows a
610   newly typed entry to be added to the list dataset and included in the available
611   list items.
612
613   TIBDynamicGrid is a TDBGrid descendent that provides for:
614   - automatic resizing of selected columns to fill the available row length
615   - automatic positioning and sizing of a "totals" control, typically at the
616     column footer, on a per column basis.
617   - DataSet resorting on header row click, sorting the dataset by the selected column.
618     A second click on the same header cell reversed the sort order.
619   - Support for a "Panel Editor". That is on clicking the indicator column, the row
620     is automatically expanded and a panel superimposed on it. The panel can have any
621     number of child controls, typically data aware controls with the same datasource
622     as the grid allowing for editing of additional fields and more complex editors.
623   - Reselection of the same row following resorting.
624   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
625     Its properties are specified on a per column basis and allows for one or more
626     columns to have their values selected from a list provided by a dataset.
627     Autocomplete and autoinsert are also available. The existing picklist editor
628     is unaffected by the extension.
629
630   TIBTreeView is a data aware TCustomTreeView.
631
632 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
633   zero scale will no longer return an error. An Int64 will be returned instead.
634
635 4. TIBTransaction now has events for Before and After Transaction End and a new function
636   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
637
638 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
639   repeated multiple times.
640
641 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
642   check used to get in the way of using Stored Procedures, and "Update or Insert"
643   statements.
644
645 7. Insert, Modify and Delete property Editors now support Query Generation from
646   Stored Procedures.
647
648 8. Three new examples illustrate the use of the new IB Controls
649

651 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
652
653 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
654   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
655   Gabor Boros for reporting this problem and for testing the improvements).
656
657 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
658   See readme.field+param.names in the doc folder.
659
660 3. IBX SQL Editors will now automatically add double quotes around column names when the database
661   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
662
663 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
664
665 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
666   actions.
667
668 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
669   thanks to Yuriy Kopnin for pointing this out).
670
671 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
672
673 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
674   for both fields and parameter setting.
675
676 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
677   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
678
679 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
680    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
681
682 11. TIBTable now has a property editor for "MasterFields"
683
684 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
685    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
686
687 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
688    of settings is unrecognised. Selecting this radio button has no effect on the settings.

691 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
692
693 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
694
695 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
696
697 1. In a TIBCustomDataset descendent, a generator now only sets the value when
698   it is null. This allows for alternative user defined setting of the generator
699
700   Many thanks to Julio Jiménez for this fix
701
702 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
703   and suggests that the user may have forgotten to install it.
704
705 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
706
707 1. Conditional compilation used to limit registration of TIntegerField to
708   Lazarus versions less than 1.1
709
710 2. When a database connection is created, character set is now by default set
711   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
712   1250 to 1254.
713
714
715 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
716
717 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
718
719
720 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
721
722 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
723   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
724
725 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
726   package is changed to do this (which it should do).
727
728 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
729
730 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
731
732 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
733
734 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
735
736 4. Property editors should now correctly resize.
737
738 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
739   (restored original functionality)
740
741 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
742   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
