1 < IBX Change Log  version                                             (2.2-0) Tue, 23 Jan 2018 11:23:09 +0000
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
7 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
8 <   information). However, this is also a very useful mechanism for returning updated computed by
9 <   column values. Values returned as a result of executing an Insert or Update statement
10 <   replace existing values in the current row for each corresponding column.
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 <   Previously, if a dataset's select query included read only (computed by) fields then
12 <   an automatic row refresh was performed after an insert or update query had been processed,
13 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 <   that an automatic refresh is no longer performed if an insert or update query contains
15 <   a returning clause that updates one or more fields on the current row. A full row
16 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17 <   field values and the select query contains read only fields. Use of Insert/update
18 <   returning should be significantly more efficient than executing a refresh query.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 <   This behaviour change is intended to be backwards compatible and there should be no need to change
21 <   existing programs, other than to improve performance by using the new capability.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
17 <   they are called when the dataset row is being deleted, there is no value in
18 <   updating the current record from the query result. Instead, a new event handler
19 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
20 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
21 <   by the query. The event handler can then interrogate the query results and
29 <   perform whatever action is necessary. For example to confirm, to the user,
30 <   the deletion of a row with the returned values.
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 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
24 <   any Computed By or Identity Columns. The IBTables example has been updated to
25 <   illustrate the computation of the employee Full Name on update.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
36 5. TIBTable: The GeneratorField property is now published.
27  
28 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
39 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
40 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
41 <   each Identity column after the insert is executed.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
31 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
45 <   Insert..Returning clause.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 8. TIBGenerator: small performance improvement by not preparing query each time
48 <   a new value is generated.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
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 < 10. Property editors will now sync table name to a System Table when "Include System
53 <    Tables" is selected and the query is for a System Table.
43 > 4. FBMessages: removal of unused messages
44  
45 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
56 <    values are no longer converted to milliseconds from TDateTime and then back again
57 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 12. Property Editors handling of Stored Procedures.
60 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
61 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
62 <      query).
63 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
66 <    can be used to select a package. If non-empty, the stored procedure name is
67 <    expected to be a stored procedure defined in the specified package and the
68 <    generated SQL will be as required for a stored procedure located in a package.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
52 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
72 <    which a stored procedure can be selected. With no package name selected, non-package
73 <    stored procedures are listed.
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 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
55 <    for password on reconnect.
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 < 16. IBDatabase: use IAttachment for connection default character set id, code page
59 <    and character set name.
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 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
82 <    DB info lookups"
62 > 4. IColumnMetaData: new method.
63  
64 < 18. IBExtract: now supports DDL Triggers.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 19. Add a property Editor for TIBUpdate.RefreshSQL.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
71 <    parameters. This stops an exception being raised when the field cannot be
90 <    located in the record buffer.
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 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 +     CaseSensitiveParams: boolean = false
75  
76 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
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 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
81 <   changes.
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  
98 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
99   Bug could result in truncated multi-byte character set values.
85  
101 3. Changes consequential on moving fbintf character set utility functions from
102   IFirebirdAPI to IAttachment.
86  
87 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
107 <   results in autocomplete ignoring prefix text.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
92 <   entering a new name into the text box.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
95 <   Firebird rather than recomputing it.
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 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
99 <   screen centre. Previously some were "poDesigned" which may be inappropriate
117 <   for multi monitor desktops.
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
101 > 5. New function added to IB.pas
102  
103 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
122 <    a transaction and always reset the object.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
105 >   This allows a Firebird Library to be loaded from an explicit path. use the
106 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 >   the library. It is possible to load Firebird libraries from different locations
108 >   simultaneously, each with a distinct IFirebirdAPI.
109  
110 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
113 <    to a gbak format archive.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 16. IBLocaldb: Drop database if error creating an empty database.
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 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
125 <    unless selected node not in current dataset.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
128 <    to TIBCustomService, and IBlocalDB code tidy up.
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 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
132 <    behaviour due to uninitialised variable.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
135 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 21. IBSQL: When Database changed ensure that all resources are freed.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
152 <    * Line Wrap on SQL Token boundaries (on user command)
153 <    * auto-complete table names in drop down list of table names
154 <    * Double click on tablename or field name adds to SQL text
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
158 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
159    TVariantArray. Seems to avoid memory corruption in Windows (probably a
160    workaround for a problem in fpc 3.0.4 win64).
145  
146 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
155 <   include remote system name.
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. TIBExtract: No longer include comment header and COMMIT statement for empty
172 <   tables when data included in output.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
175 <   and timing information to be written to stdout. This may be used to locate
176 <   performance bottlenecks.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 4. SQLParser: only call "OnChanging" event handler when value is different.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
173 <   that BindFields is called when the query is next activated. Avoids FieldName
184 <   not found error.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
176 <   purpose and allows the programmer to define any action they want for Update, Insert
177 <   or Delete. This may be complex SQL (similar to a Trigger), application specific
178 <   filtering of updates, or use of statements such as Grant or Revoke instead of
179 <   normal DML. See User Manual for more information.
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 < IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 1. TIBEvents: Fix uninitialised variable that could result in lost events.
183 > 9. IBUtils code tidy up.
184  
185 < 2. TIBExtract: Added support for FB3 "USAGE" privilege.
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 < 3. TIBExtract: data formatted as Charset set "octets" is now output using
199 <   hexadecimal notation.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
193 <   using a simple XML format.
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 < 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
198 <   grants to these objects.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
201 <   dependency problems restoring complex databases.
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 < 7. TIBXScript: This component has been restructured to allow for the processing of
204 <   embedded XML in INSERT statements and to support interactive sources in addition
205 <   to non-interactive data sources such as files.
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 < 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 9. TIBXScript: ISQL compatiable Set statements are now supported:
210 <   SET SQL DIALECT
218 <   SET TERM
219 <   SET AUTODDL
220 <   SET BAIL
221 <   SET ECHO
222 <   SET COUNT
223 <   SET STATS
224 <   SET NAMES <character set>
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 10. IBVersion unit added to hold current IBX Version Number information.
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 < 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
218 <    and domain definitions.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
221 <    fully supported.
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 < 13. TIBExtract: when a database dump includes data, the generator values are now also set.
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 < 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
232  
233 < IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
233 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items

235  
236 < See also doc/IBX4LazarusGuide.pdf for important information on
241 < upgrading to IBX2.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 1. Size property of TIBStringField is now the width in characters of the field
239 <   and not the byte length. This applies only to multi-byte character sets such
240 <   as UTF8. The original approach aligned with TStringField. However, the TStringField
241 <   code is not recognised as a bug and hence this change to align the behaviour.
247 <   The TStringField change is expected in fpc 3.2.0.
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 < 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
250 <   true (default) then Size property value saved in the lfm is ignored. Size is
251 <   always set from the dynamic information read from the database. It is unclear
252 <   why anyone would want to override this and set Size to false.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 3. ibxscript: should now handle correctly a Case..End statement within a procedure
255 <   block.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
258 <   exist when an attempt is made to connect to it (run time only) then an attempt
259 <   is made to create the database.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
250 <   has been successfully created as a result of a call to CreateDatabase or when
251 <   creating a database after it was found not to exist.
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 < 6.  DBControlGrid: a race condition could result in the wrong row image being
266 <    written to the cache. This has been avoided by a trip round the message
267 <    loop before rendering the row image.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
257 <    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
271 <    known to risk corrupt rendering of row images when the control is first
272 <    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
273 <    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
260 <    a TDateEdit control located on an editor panel.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
278 9.  TIBExtract: brought up-to-date plus many bug fixes.
262  
263 < 10. DBControlGrid: Removed memory leak when updating rows.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
265 > 1. Change syntax to Mode Delphi
266  
267 < IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
271 <   when target codepage is CP_NONE. This is a workaround for
288 <   http://bugs.freepascal.org/view.php?id=30622.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 2. DBLog option removed from TIBStatisticalService - not supported by server
291 <   since Firebird 1.5.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
276 <   similar.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 4. IBCodePage: updated mapping between codepages and character id.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
299 <   Firebird. Character sets with a char width of two are not UTF16.
280 > 7. Testsuite updated for Delphi
281  
282 < 6. Strings received from the database are now always transliterated into UTF8
302 <   regardless of the database character set or connection character set. This
303 <   is for compatibility with the LCL.

284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 1. IBBlob: Defer reading of blob until read method called. This avoids having to
288 <   read in an entire blob just to get the size of the blob. General performance
309 <   improvement when opening datasets containing blobs.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 2. Clearing a  Blob now sets the corresponding field's modified flag.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 3. IBLookupCombo: When not performing auto-complete, original query sort order
293 <   is now used.
292 > 4. Array Handling: fix problem with text arrays with character set none. When the
293 >   DB connection has a default character set (e.g. UTF8), an error is raised by
294 >   Firebird if the space allocated is not enough to allow for transliteration, even
295 >   though it is not required for character set none.
296  
297 < 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
317 <   determined.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
302 <   lazarus 1.6.0
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
305 <   compilation error.
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.

307 < IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
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. No character set specified for connection: when a text blob is retrieved, the
311 <  character set is determined by looking up the native character set using then
312 <  Firebird API. Otherwise a text mode blob is assumed to have the same character
332 <  set as the connection.
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 < 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
335 <   for Login Dialog returing a change to the database path.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
338 <   to be changed from that given in the TIBDatabase/TIBServer component and for the
339 <   entered value to be saved on a project specific basis (design time only).
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
342 <   column fieldname. If they are the same then it is acts as a look up for the KeyValue
343 <   Otherwise, it sets the column text to the selected ListField Value.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
346 <   column width.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
349 <   and a case insensitive search is requested.
322 > 1. Initial Release
323  
351 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
352   or column ListSource.
353
354 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
355   unprepare) when closing and the text has not changed.
356
357 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
358   Less likely to cause a cursor re-use error on Windows.
359
360 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
361   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
362
363 11. TIBTreeView: Guard against nil destination on record changed
364
365 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
366    string type with the code page set to reflect the returned field encoding after
367    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
368    earlier versions.
369
370 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
371    will now result in transliteration to the code page specified for the Firebird driver
372    if the assigned string has a different code page. FPC 3.0.0 onwards only.
373
374 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
375    is ignored and the lc_ctype value, when the database is opened, is set to align with
376    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
377    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
378    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
379    the GETACP is used to determine the Windows code page.
380
381 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
382    name used as the lc_ctype when the database was opened. Only valid while the
383    Database is connected.
384
385 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
386    id that corresponds to the DefaultCharSetName.

389
390 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
391   path is given and database attach fails due to access permission issues on the
392   temp directory or security database, then the attach is retried with "localhost:"
393   prefixing the databasename. This should avoid problems when the database has to
394   be accessed by a local (e.g. classic) server and libfbembed is used.
395
396 2. Windows: revised search order for Firebird DLL:
397     i.   The Firebird Embedded Server in the application Directory.
398     ii.  If the FIREBIRD environment variable is set then the directory this
399          points to is searched for the FB Client DLL and then then underlying
400          "bin" directory.
401     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
402          is used to locate the Firebird installation directory and the underlying
403          "bin" directory is searched for the FB Client DLL.
404     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
405          are searched for the FB Client DLL.
406     v.   The PATH Environment variable is used to search for the FB Client DLL.
407     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
408
409 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
410   See doc/readme.scriptengine and example applications.
411
412 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
413   simplify the use of the embedded firebird server on both Linux and Windows platforms.
414   See dpc/readme.localdatabase and example applications.
415
416 5. IBDynamicGrid: Reordering on column header click should now also work for
417   dynamic columns.
418
419 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
420   between incrementing/decrementing the lock count and signalling the event.
421
422 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
423
424 1.3.2 was never formally released and only made available as beta copies.
425
426 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
427
428 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
429
430 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
431
432 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
433   i.e. when it is a calculated field
434
435 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
436   This problem was due to a race condition between recalculating row heights and
437   determining which row was selected by the mouse click. The row height calculation
438   is now deferred by an extra trip round the message loop allowing the row to
439   be always calculated on the current grid layout rather than risking it being
440   calculated on the grid layout after the expanded row has been shrunk.
441
442 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
443   Windows.
444
445 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
446   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
447   to be determined at runtime. See doc/readme.charactersets.html.
448
449 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
450   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
451
452 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
453   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
454   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
455
456   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
457   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
458   implies no truncation.
459
460 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
461
462 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
463   (avoids "Not in Edit Mode" error).
464
465 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
466
467 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
468    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
469
470 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
471
472 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
473
474 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
475
476 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
477
478 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
479
480 1.   OnCloseUp Event Handler added to TDBLookupProperties
481
482 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
483     problem with row size when exception is called.
484
485 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
486
487 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
488     in a TCustomComboBox and ignores return key if in a TCustomMemo
489
490 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
491     keyed in i.e. when autocomplete not performed
492
493 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
494     console mode applications with all LCL required functions (builtin dialogs and
495     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
496     not included in your project, IBX should compile and link with a console mode program.
497     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
498     console mode application or the IDE will automatically assume that your
499     application is GUI based. Instead, you should include the ibexpressconsolemode package.
500
501     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
502     to use the built in dialogs and cursor management. IBDialogs is
503     included by default if "ibexpress" is in your project source's "uses" clause.
504     This should be the case for all projects created through the IDE. This is why
505     you do not want to add the ibexpress package to console mode applications. The
506     ibexpressconsolemode package has been created to allow console mode programs
507     to avoid adding LCL dependencies when using IBX, while still having the
508     unit search paths set up correctly.
509
510     Existing users should check to ensure that the "ibexpress" unit is included in
511     each project's source file (*.lpr).
512
513     You may find that in order for the IDE to recognise that ibexpressconsolemode
514     exists, you have to first open the package in the IDE and then close it. This
515     adds it to the most recently accessed packages list. To make it permanently
516     available, add the package name to lazarus' staticpackages.inc file.
517
518         Thanks to Julio Jiménez for suggesting support of console mode.
519
520 7.   SQL Parser can now accept quoted strings that include new lines
521
522 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
523     of text on start of edit. This is particularly useful when tabbing to a
524     column and then inserting text.
525
526 9.   New Examples provided for IB Services and ISQLMonitor.
527
528 10. Fix error when writing to blob streams that recorded only the last buffer
529    write in the blob stream. In most cases, this did not cause a problem as the
530    IB Blob Stream is written in a single write. However, with the TDBImage, write
531    of a graphic type prefix was lost which caused a problem when the image could
532        not be automatically recognised.
533
534 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
535    already open" errors due to random numbers used for the cursor name being identical.
536
537 12. IBTable: corrected error that could result in an "Index out of bounds" error
538    when opening the table and the Primary Key is the last or only column in the
539    table. Thanks to Rick Hoover for the fix.
540
541 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
542    of "UTF-8", and update list of available database character sets. Existing
543    users should check the current lc_ctype setting in their applications.
544
545 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
546
547 1.  Firebird Services: avoid List Index error when opening a service with an
548    empty Params property.
549
550 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
551    Link now set up in Loaded method - avoids occasional failure to apply
552    SQL markup on initial open.
553
554 3.  "Employees" example performance improvements when scrolling.
555
556 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
557    TFrame. Force recaching of selected frame to avoid GTK race (results in a
558    random image cached).
559
560 5.  DBControlGrid: Should now react to changes in panel height at run time.
561
562 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
563    even when further rows exist.
564
565 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
566    always be derived from panel height and setting this property can cause confusion.
567    Note for existing projects: to avoid a missing property error at run time,
568    each form using the DBControlGrid must be opened, updated and saved in the IDE
569    in order to remove the property value from the lfm.
570
571
572 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
573
574 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
575    call Prepare before setting parameter values.
576
577 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
578
579 3.  Code tidyup and more robust handling of dsql information result vector.
580
581 4.  Support for centralised handling of transaction status changes. TIBTransaction
582    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
583    and "AfterExecQuery". The first three are called after the same event is called
584    for an IBCustomDataSet descendent using the Transaction. The fourth is called
585    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
586    enable monitoring of transaction status changes for a given transaction to be
587    handled in a single place. For example, when a change to the dataset occurs
588    an indicator can be set that shows the user that in order to save changes,
589    the transaction should be committed.  Rather than doing this per dataset, this
590    can now be done per transaction.
591
592 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
593    the dataset is scrolled. However, any changes to the current row are, by default,
594    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
595    have a new property "DataSetCloseAction" that adds automatic posting of changes
596    on dataset close. If this property is set to dcDiscardChanges (default) then the
597    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
598    then IBX will attempt to post any unsaved changes before the dataset is closed
599    (and after the BeforeClose event handler is called). The exception is when the
600    dataset is being closed as a result of a transaction rollback. In this case,
601    no action is taken and any unsaved  changes are discarded. This avoids both
602    unnecessary overhead and the risk that a validation error may occur in the Post
603    raising an exception and thereby preventing a rollback.
604
605 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
606    In earlier versions, the Display Width was set to the maximum byte width rather than the character
607    width. Display Widths are now corrected by dividing by the max byte width per character.
608    For UTF8 character sets, the byte width is four and hence the Display Width will be
609    the byte width divided by 4. The byte width of each character set is determined
610    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
611    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
612
613 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
614
615 8.  IBLookupComboEditBox: List should now always be restored to full list when the
616    control loses focus. Default Key press default interval reduced to 200ms.
617
618 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
619    when dataset rows are less than visible rows.
620
621 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
622    does not exist or DataSet is empty. More responsive on dataset open. New event
623    OnRestorePosition. Column sort disabled if no header row.
624
625 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
626    while dataset state is dsInsert. Avoids posting errors.
627
628 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
629    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
630
631 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
632
633 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
634    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
635    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
636    always "posts" the current record regardless or whether or not it may be more appropriate
637    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
638    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
639    as the first action of the "Post" method and allows the handler to convert the Post
640    into a Cancel if that is the appropriate action on moving to a different row. This is
641    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
642    raised here, but it may still be more appropriate to validate a post and signal
643    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
644
645 15. On Unix derived systems, the Firebird library name can now be given as a colon
646    separated list. Each library name on the list is tried in turn, in left to right
647    order with the first found being used as the firebird library. By default, on Linux,
648    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
649    overidden by the FBLIB environment variable or the OnGetLibraryName function.
650
651    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
652    then it will still attempt to access the database via the Firebird Server and will
653    require a username and password. If only the pathname is given, then the username
654    and password should be omitted and the unix file permissions are used to grant
655    access.
656
657 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
658
659 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
660    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
661    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
662    corresponds to a row of the linked DataSource. Any data aware control on the
663    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
664
665 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
666   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
667   takes place during database access. This may be useful when there are performance issues with
668   the change of cursor. Setting the property to false suppresses the change of cursor.
669
670 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
671   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
672   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
673   making all changes permanent immediately rather than when the transaction is explicitly
674   committed.
675
676 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
677   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
678
679 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
680
681 Development version only.
682
683 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
684
685 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
686   This is typically used during an "OnBeforeOpen" event handler to manipulate the
687   "Where" and "Having" clauses to implement user specified filters of arbitrary
688   complexity.
689
690 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
691   three new data aware controls dependent on IBX and which make use of the SQL Parser.
692   These are:
693
694   - TIBLookupComboEditBox
695   - TIBDynamicGrid
696   - TIBTreeview
697
698   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
699   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
700   to revise the available list and restrict it to items that are prefixed by the
701   typed text (either case sensitive or case insensitive). Autoinsert allows a
702   newly typed entry to be added to the list dataset and included in the available
703   list items.
704
705   TIBDynamicGrid is a TDBGrid descendent that provides for:
706   - automatic resizing of selected columns to fill the available row length
707   - automatic positioning and sizing of a "totals" control, typically at the
708     column footer, on a per column basis.
709   - DataSet resorting on header row click, sorting the dataset by the selected column.
710     A second click on the same header cell reversed the sort order.
711   - Support for a "Panel Editor". That is on clicking the indicator column, the row
712     is automatically expanded and a panel superimposed on it. The panel can have any
713     number of child controls, typically data aware controls with the same datasource
714     as the grid allowing for editing of additional fields and more complex editors.
715   - Reselection of the same row following resorting.
716   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
717     Its properties are specified on a per column basis and allows for one or more
718     columns to have their values selected from a list provided by a dataset.
719     Autocomplete and autoinsert are also available. The existing picklist editor
720     is unaffected by the extension.
721
722   TIBTreeView is a data aware TCustomTreeView.
723
724 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
725   zero scale will no longer return an error. An Int64 will be returned instead.
726
727 4. TIBTransaction now has events for Before and After Transaction End and a new function
728   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
729
730 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
731   repeated multiple times.
732
733 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
734   check used to get in the way of using Stored Procedures, and "Update or Insert"
735   statements.
736
737 7. Insert, Modify and Delete property Editors now support Query Generation from
738   Stored Procedures.
739
740 8. Three new examples illustrate the use of the new IB Controls
741
742
743 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
744
745 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
746   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
747   Gabor Boros for reporting this problem and for testing the improvements).
748
749 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
750   See readme.field+param.names in the doc folder.
751
752 3. IBX SQL Editors will now automatically add double quotes around column names when the database
753   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
754
755 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
756
757 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
758   actions.
759
760 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
761   thanks to Yuriy Kopnin for pointing this out).
762
763 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
764
765 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
766   for both fields and parameter setting.
767
768 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
769   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
770
771 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
772    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
773
774 11. TIBTable now has a property editor for "MasterFields"
775
776 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
777    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
778
779 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
780    of settings is unrecognised. Selecting this radio button has no effect on the settings.
781

783 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
784
785 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
786
787 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
788
789 1. In a TIBCustomDataset descendent, a generator now only sets the value when
790   it is null. This allows for alternative user defined setting of the generator
791
792   Many thanks to Julio Jiménez for this fix
793
794 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
795   and suggests that the user may have forgotten to install it.
796
797 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
798
799 1. Conditional compilation used to limit registration of TIntegerField to
800   Lazarus versions less than 1.1
801
802 2. When a database connection is created, character set is now by default set
803   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
804   1250 to 1254.
805
806
807 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
808
809 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
810
811
812 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
813
814 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
815   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
816
817 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
818   package is changed to do this (which it should do).
819
820 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
821
822 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
823
824 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
825
826 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
827
828 4. Property editors should now correctly resize.
829
830 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
831   (restored original functionality)
832
833 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
834   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
