1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
2  
3 < IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 < all previous copies of the IBX source code tree before installing this release.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
5  
6 < The IBX packages used by most users have not changed, with one exception. The
7 < IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 < to use the IBServices unit in your applications, please add the iblegacyServices
9 < to the list of dependencies. To do this, open the Project Inspector and select
10 < Add->New Requirement and select "ibLegacyServices" from the list of available
11 < packages.
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 < 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 <   the IBServices unit providing what is intended to be a clearer and easier to
15 <   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 <   more information and the guide to "Firebird Service Management Using IBX".
17 <   As indicated above, the legacy services components are still available and
18 <   provided in a separate package. There is no need to update working applications
19 <   using the older versions except for an additional package dependency.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 < 2. The IBX packages and source code tree have been re-organised in an attempt to
22 <   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 <   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 <   new set of IBX packages.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
17 <   updated to use the new Services API components.
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. The iblocal package has been updated to use the new Services API components.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
31 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32   TIBXSecurityService. It had been wrongly classified in the previous version
33   as a per database configuration item. It is global to a server and hence
34   correctly positioned as part of the Security Package. In the DBAdmin example,
35   the setting has moved to the mappings page.
27  
28 < 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 <   are ignored.
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 < 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
31 <   closed before the database is dropped. Before and After Disconnect event handlers
42 <   are also fired.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 < 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 <   is started and not just the first time.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
36 <   depenendency with comp type.
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. IBDataOutput: select query data output is now sent to stdout instead of stderr.
43 > 4. FBMessages: removal of unused messages
44  
45 < 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 <    then this is recognised and not ignored.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 < 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 <    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 <    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 <    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 <    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 <    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 <    counters for the select query. Note: stats accumulate after each fetch from
63 <    the database. To get total query cost after open, call the "Last" method
64 <    and then GetPerfStatistics.
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 <    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
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 < 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
55 <    in parenthesises.
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 < 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
59 <    SQL identifiers are always delimited by double quotes. If false, then they are
60 <    only delimited if the identifier is a reserved word, contains lower case or special
74 <    characters. Set this property to true to retain previous behaviour.
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 < 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 <    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
62 > 4. IColumnMetaData: new method.
63  
64 < 16. TIBDataSet, TIBQuery, TIBTable: addition:
65 <       property MasterDetailDelay: integer {defaults to zero}
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 <    When non-zero and the dataset is a detail table referencing a master table
83 <    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 <    then a synchronisation delay is added (in milliseconds) between the master
85 <    row changing and the detail dataset being re-opened. If the master dataset
86 <    is scrolled before the delay expires then the delay is reset. This can be used
87 <    to avoid performance overheads when scrolling through a large master dataset.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 <    Note: uses fptimer and hence requires a thread manager. Under Linux the
71 <    chreads unit must be included in your project. TTimer is not used in order
91 <    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
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 < 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
74 <    with Extract Option eoDatabase.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
77 <    When a deLayoutChanged event is reported on the ListSource dataset, the
78 <    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 <    relationship with the control's datasource (master).
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 < 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
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  
103 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104    stubs. Pedantic fix really, as procedures output in dependency order anyway.
85  
106 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107    DDL (Firebird 3 and later only).
86  
87 < 22. TIBLookupComboBox Autocomplete Fixes:
110 <    i. Only appended text is now selected after autocomplete.
111 <    ii. Uppercase keys no longer ignored for autocomplete.
112 <    iii. Retain Prefix case is now honoured correctly.
113 <    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114 <        before autocomplete performed. i.e. behaviour now the same as when
115 <        no DataSource assigned.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 <    between SQL statements.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 < 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
92 <    ObjectNames are converted to upper case before matching against metadata object
122 <    names, unless the objectname is delimited by double quotes, in which case, the
123 <    double quotes are removed and the remaining string is used (unmodified) to match
124 <    against the metadata object name.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 <    If true then the ObjectName is used as is without modification and matched
95 <    against the metadata object name. No attempt is made to remove double quotes.
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 < 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
99 <    with eoTrigger, these extract types can be used to select only Database Triggers,
131 <    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
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 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
101 > 5. New function added to IB.pas
102  
103 < NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
136 < AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
137 < RELEASE.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
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. IBExtract: Identity columns - add additional check for null column for generator name.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
113 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
145 <   information). However, this is also a very useful mechanism for returning updated computed by
146 <   column values. Values returned as a result of executing an Insert or Update statement
147 <   replace existing values in the current row for each corresponding column.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 <   Previously, if a dataset's select query included read only (computed by) fields then
116 <   an automatic row refresh was performed after an insert or update query had been processed,
117 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
152 <   that an automatic refresh is no longer performed if an insert or update query contains
153 <   a returning clause that updates one or more fields on the current row. A full row
154 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
155 <   field values and the select query contains read only fields. Use of Insert/update
156 <   returning should be significantly more efficient than executing a refresh query.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 <   This behaviour change is intended to be backwards compatible and there should be no need to change
120 <   existing programs, other than to improve performance by using the new capability.
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 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
125 <   they are called when the dataset row is being deleted, there is no value in
163 <   updating the current record from the query result. Instead, a new event handler
164 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
165 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
166 <   by the query. The event handler can then interrogate the query results and
167 <   perform whatever action is necessary. For example to confirm, to the user,
168 <   the deletion of a row with the returned values.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
128 <   any Computed By or Identity Columns. The IBTables example has been updated to
129 <   illustrate the computation of the employee Full Name on update.
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 < 5. TIBTable: The GeneratorField property is now published.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
135 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
178 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
179 <   each Identity column after the insert is executed.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
182 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
183 <   Insert..Returning clause.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 8. TIBGenerator: small performance improvement by not preparing query each time
186 <   a new value is generated.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 10. Property editors will now sync table name to a System Table when "Include System
191 <    Tables" is selected and the query is for a System Table.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
193 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
194    values are no longer converted to milliseconds from TDateTime and then back again
195    to TDateTime (the conversion to milliseconds is the default TDataset approach).
145  
146 < 12. Property Editors handling of Stored Procedures.
198 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
199 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
200 <      query).
201 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
204 <    can be used to select a package. If non-empty, the stored procedure name is
205 <    expected to be a stored procedure defined in the specified package and the
206 <    generated SQL will be as required for a stored procedure located in a package.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
151 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
152 <    which a stored procedure can be selected. With no package name selected, non-package
211 <    stored procedures are listed.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
155 <    for password on reconnect.
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 < 16. TIBDatabase: use IAttachment for connection default character set id, code page
217 <    and character set name.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
220 <    DB info lookups"
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 19. Add a property Editor for TIBUpdate.RefreshSQL.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
173 <    parameters. This stops an exception being raised when the field cannot be
228 <    located in the record buffer.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 21. Property Editors now automatically include System Tables when opened and when the query table
176 <    is a System Table.
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 < 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
234 <    This avoids errors due to a stale SQRB or SRB being used for the next query.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 23. IBServices: Service attach parameters now include "expected_db". This is used to
237 <    add the SPB item isc_spb_expected_db. This names a database using
238 <    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
239 <    database. examples/services re-written to illustrate use of "expected_db".
183 > 9. IBUtils code tidy up.
184  
185 < 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
186 <    This avoids truncated backups when the server returns a timeout (busy) response.
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 < 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
193 <    databasenames. These are respectively expanded to the local system's temp directory
194 <    (including trailing delimiter) or to a prescribed data directory (including
195 <    trailing delimiter). Under Unix systems the data directory is a hidden directory
250 <    in the user's home directory. The hidden directory name is either the string returned
251 <    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
252 <    Under Windows, the directory is the same as the Data Directory as decribed
253 <    above but instead prefixed by the User's application data path. These may be
254 <    used to improve application portability for Personal Databases.
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 < 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
198 <    this has not worked for a long time and is not useful either. FieldDefs should be
258 <    managed using the Fields Editor as with any other dataset. To access the fields
259 <    editor for a TIBTable component, double click on the component. The fields editor
260 <    is then displayed.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 28. TIBDatabaseInfo: new properties/function
201 <     * DateDBCreated (returns date/time database created)
264 <     * TransactionCount (returns no. of active transactions)
265 <     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
266 <     * PagesFree (Firebird 3 or later)
267 <     * PagesUsed (Firebird 3 or later)
268 <     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
269 <     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
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 < 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
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 < 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
210 <    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
213 <    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
214 <    firing during backup and restore.
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 < 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
218 <    for verbose output using the new property "StatisticsRequested".
284 <    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
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 < 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
226 <    palette. This uses the online validation feature added in Firebird 2.5. The
227 <    services's properties enable inclusion/exclusion of tables and indexes using
228 <    regular expressions. See.
292 <    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
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 < 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
231 <    option on a database.
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 < 37. TIBCustomService: Assign method implemented to allow copying of service login
234 <    context between service API components. "Detach" method now only detaches
299 <    service when last reference to the service interface detaches. Tidy up of
300 <    code for SetActive and Attach methods including password hiding.
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 < 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
303 <    and used to determine the auth method and protocol used for the connection.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
239 <    a Create Database Statement generated by IBX.
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 < 40. All IBServices now have an additional published property "PortNo". This may
309 <    be set to a non-standard port number when necessary. If zero then the default
310 <    port number is used.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
313 <    and not just the mouse.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
250 <    image index and selected image index for each node to be set from a database field.
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 < 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
321 <    then database schema includes grants to all users. If not present then the
322 <    only user grants included are those to User PUBLIC.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 45. TIBTreeView: performance improvement. When expanding include both expanded node
257 <    and child nodes in dataset.
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 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 +    of const passed to IAttachment.OpenCursor, etc.
261

262  
263 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
331 <   changes.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
334 <   Bug could result in truncated multi-byte character set values.
265 > 1. Change syntax to Mode Delphi
266  
267 < 3. Changes consequential on moving fbintf character set utility functions from
268 <   IFirebirdAPI to IAttachment.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
342 <   results in autocomplete ignoring prefix text.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
276 <   entering a new name into the text box.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
348 <   Firebird rather than recomputing it.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 8. Property Editor positioning tidy up: All IBX Property editors should now be
351 <   screen centre. Previously some were "poDesigned" which may be inappropriate
352 <   for multi monitor desktops.
280 > 7. Testsuite updated for Delphi
281  
282 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
285 <    a transaction and always reset the object.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
293 <    to a gbak format archive.
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 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 16. IBLocaldb: Drop database if error creating an empty database.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
302 <    unless selected node not in current dataset.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
305 <    to TIBCustomService, and IBlocalDB code tidy up.
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 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
308 <    behaviour due to uninitialised variable.
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 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
311 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
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 < 21. IBSQL: When Database changed ensure that all resources are freed.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
387 <    * Line Wrap on SQL Token boundaries (on user command)
388 <    * auto-complete table names in drop down list of table names
389 <    * Double click on tablename or field name adds to SQL text
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
394 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
395 <    workaround for a problem in fpc 3.0.4 win64).
322 > 1. Initial Release
323  
397 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
398
399 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
400
401 IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
402
403 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
404   include remote system name.
405
406 2. TIBExtract: No longer include comment header and COMMIT statement for empty
407   tables when data included in output.
408
409 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
410   and timing information to be written to stdout. This may be used to locate
411   performance bottlenecks.
412
413 4. SQLParser: only call "OnChanging" event handler when value is different.
414
415 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
416
417 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
418   that BindFields is called when the query is next activated. Avoids FieldName
419   not found error.
420
421 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
422   purpose and allows the programmer to define any action they want for Update, Insert
423   or Delete. This may be complex SQL (similar to a Trigger), application specific
424   filtering of updates, or use of statements such as Grant or Revoke instead of
425   normal DML. See User Manual for more information.
426
427 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
428
429 1. TIBEvents: Fix uninitialised variable that could result in lost events.
430
431 2. TIBExtract: Added support for FB3 "USAGE" privilege.
432
433 3. TIBExtract: data formatted as Charset set "octets" is now output using
434   hexadecimal notation.
435
436 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
437   using a simple XML format.
438
439 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
440   grants to these objects.
441
442 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
443   dependency problems restoring complex databases.
444
445 7. TIBXScript: This component has been restructured to allow for the processing of
446   embedded XML in INSERT statements and to support interactive sources in addition
447   to non-interactive data sources such as files.
448
449 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
450
451 9. TIBXScript: ISQL compatiable Set statements are now supported:
452   SET SQL DIALECT
453   SET TERM
454   SET AUTODDL
455   SET BAIL
456   SET ECHO
457   SET COUNT
458   SET STATS
459   SET NAMES <character set>
460
461 10. IBVersion unit added to hold current IBX Version Number information.
462
463 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
464    and domain definitions.
465
466 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
467    fully supported.
468
469 13. TIBExtract: when a database dump includes data, the generator values are now also set.
470
471 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
472
473 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
474
475 See also doc/IBX4LazarusGuide.pdf for important information on
476 upgrading to IBX2.
477
478 1. Size property of TIBStringField is now the width in characters of the field
479   and not the byte length. This applies only to multi-byte character sets such
480   as UTF8. The original approach aligned with TStringField. However, the TStringField
481   code is not recognised as a bug and hence this change to align the behaviour.
482   The TStringField change is expected in fpc 3.2.0.
483
484 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
485   true (default) then Size property value saved in the lfm is ignored. Size is
486   always set from the dynamic information read from the database. It is unclear
487   why anyone would want to override this and set Size to false.
488
489 3. ibxscript: should now handle correctly a Case..End statement within a procedure
490   block.
491
492 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
493   exist when an attempt is made to connect to it (run time only) then an attempt
494   is made to create the database.
495
496 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
497   has been successfully created as a result of a call to CreateDatabase or when
498   creating a database after it was found not to exist.
499
500 6.  DBControlGrid: a race condition could result in the wrong row image being
501    written to the cache. This has been avoided by a trip round the message
502    loop before rendering the row image.
503
504 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
505    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
506    known to risk corrupt rendering of row images when the control is first
507    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
508    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
509
510 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
511    a TDateEdit control located on an editor panel.
512
513 9.  TIBExtract: brought up-to-date plus many bug fixes.
514
515 10. DBControlGrid: Removed memory leak when updating rows.
516
517 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
518
519 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
520
521 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
522   when target codepage is CP_NONE. This is a workaround for
523   http://bugs.freepascal.org/view.php?id=30622.
524
525 2. DBLog option removed from TIBStatisticalService - not supported by server
526   since Firebird 1.5.
527
528 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
529   similar.
530
531 4. IBCodePage: updated mapping between codepages and character id.
532
533 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
534   Firebird. Character sets with a char width of two are not UTF16.
535
536 6. Strings received from the database are now always transliterated into UTF8
537   regardless of the database character set or connection character set. This
538   is for compatibility with the LCL.
539
540 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
541
542 1. IBBlob: Defer reading of blob until read method called. This avoids having to
543   read in an entire blob just to get the size of the blob. General performance
544   improvement when opening datasets containing blobs.
545
546 2. Clearing a  Blob now sets the corresponding field's modified flag.
547
548 3. IBLookupCombo: When not performing auto-complete, original query sort order
549   is now used.
550
551 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
552   determined.
553
554 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
555
556 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
557   lazarus 1.6.0
558
559 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
560   compilation error.
561
562 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
563
564 1. No character set specified for connection: when a text blob is retrieved, the
565  character set is determined by looking up the native character set using then
566  Firebird API. Otherwise a text mode blob is assumed to have the same character
567  set as the connection.
568
569 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
570   for Login Dialog returing a change to the database path.
571
572 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
573   to be changed from that given in the TIBDatabase/TIBServer component and for the
574   entered value to be saved on a project specific basis (design time only).
575
576 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
577   column fieldname. If they are the same then it is acts as a look up for the KeyValue
578   Otherwise, it sets the column text to the selected ListField Value.
579
580 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
581   column width.
582
583 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
584   and a case insensitive search is requested.
585
586 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
587   or column ListSource.
588
589 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
590   unprepare) when closing and the text has not changed.
591
592 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
593   Less likely to cause a cursor re-use error on Windows.
594
595 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
596   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
597
598 11. TIBTreeView: Guard against nil destination on record changed
599
600 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
601    string type with the code page set to reflect the returned field encoding after
602    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
603    earlier versions.
604
605 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
606    will now result in transliteration to the code page specified for the Firebird driver
607    if the assigned string has a different code page. FPC 3.0.0 onwards only.
608
609 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
610    is ignored and the lc_ctype value, when the database is opened, is set to align with
611    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
612    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
613    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
614    the GETACP is used to determine the Windows code page.
615
616 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
617    name used as the lc_ctype when the database was opened. Only valid while the
618    Database is connected.
619
620 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
621    id that corresponds to the DefaultCharSetName.
622
623 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
624
625 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
626   path is given and database attach fails due to access permission issues on the
627   temp directory or security database, then the attach is retried with "localhost:"
628   prefixing the databasename. This should avoid problems when the database has to
629   be accessed by a local (e.g. classic) server and libfbembed is used.
630
631 2. Windows: revised search order for Firebird DLL:
632     i.   The Firebird Embedded Server in the application Directory.
633     ii.  If the FIREBIRD environment variable is set then the directory this
634          points to is searched for the FB Client DLL and then then underlying
635          "bin" directory.
636     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
637          is used to locate the Firebird installation directory and the underlying
638          "bin" directory is searched for the FB Client DLL.
639     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
640          are searched for the FB Client DLL.
641     v.   The PATH Environment variable is used to search for the FB Client DLL.
642     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
643
644 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
645   See doc/readme.scriptengine and example applications.
646
647 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
648   simplify the use of the embedded firebird server on both Linux and Windows platforms.
649   See dpc/readme.localdatabase and example applications.
650
651 5. IBDynamicGrid: Reordering on column header click should now also work for
652   dynamic columns.
653
654 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
655   between incrementing/decrementing the lock count and signalling the event.
656
657 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
658
659 1.3.2 was never formally released and only made available as beta copies.
660
661 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
662
663 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
664
665 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
666
667 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
668   i.e. when it is a calculated field
669
670 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
671   This problem was due to a race condition between recalculating row heights and
672   determining which row was selected by the mouse click. The row height calculation
673   is now deferred by an extra trip round the message loop allowing the row to
674   be always calculated on the current grid layout rather than risking it being
675   calculated on the grid layout after the expanded row has been shrunk.
676
677 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
678   Windows.
679
680 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
681   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
682   to be determined at runtime. See doc/readme.charactersets.html.
683
684 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
685   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
686
687 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
688   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
689   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
690
691   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
692   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
693   implies no truncation.
694
695 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
696
697 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
698   (avoids "Not in Edit Mode" error).
699
700 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
701
702 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
703    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
704
705 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
706
707 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
708
709 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
710
711 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
712
713 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
714
715 1.   OnCloseUp Event Handler added to TDBLookupProperties
716
717 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
718     problem with row size when exception is called.
719
720 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
721
722 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
723     in a TCustomComboBox and ignores return key if in a TCustomMemo
724
725 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
726     keyed in i.e. when autocomplete not performed
727
728 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
729     console mode applications with all LCL required functions (builtin dialogs and
730     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
731     not included in your project, IBX should compile and link with a console mode program.
732     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
733     console mode application or the IDE will automatically assume that your
734     application is GUI based. Instead, you should include the ibexpressconsolemode package.
735
736     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
737     to use the built in dialogs and cursor management. IBDialogs is
738     included by default if "ibexpress" is in your project source's "uses" clause.
739     This should be the case for all projects created through the IDE. This is why
740     you do not want to add the ibexpress package to console mode applications. The
741     ibexpressconsolemode package has been created to allow console mode programs
742     to avoid adding LCL dependencies when using IBX, while still having the
743     unit search paths set up correctly.
744
745     Existing users should check to ensure that the "ibexpress" unit is included in
746     each project's source file (*.lpr).
747
748     You may find that in order for the IDE to recognise that ibexpressconsolemode
749     exists, you have to first open the package in the IDE and then close it. This
750     adds it to the most recently accessed packages list. To make it permanently
751     available, add the package name to lazarus' staticpackages.inc file.
752
753         Thanks to Julio Jiménez for suggesting support of console mode.
754
755 7.   SQL Parser can now accept quoted strings that include new lines
756
757 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
758     of text on start of edit. This is particularly useful when tabbing to a
759     column and then inserting text.
760
761 9.   New Examples provided for IB Services and ISQLMonitor.
762
763 10. Fix error when writing to blob streams that recorded only the last buffer
764    write in the blob stream. In most cases, this did not cause a problem as the
765    IB Blob Stream is written in a single write. However, with the TDBImage, write
766    of a graphic type prefix was lost which caused a problem when the image could
767        not be automatically recognised.
768
769 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
770    already open" errors due to random numbers used for the cursor name being identical.
771
772 12. IBTable: corrected error that could result in an "Index out of bounds" error
773    when opening the table and the Primary Key is the last or only column in the
774    table. Thanks to Rick Hoover for the fix.
775
776 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
777    of "UTF-8", and update list of available database character sets. Existing
778    users should check the current lc_ctype setting in their applications.
779
780 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
781
782 1.  Firebird Services: avoid List Index error when opening a service with an
783    empty Params property.
784
785 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
786    Link now set up in Loaded method - avoids occasional failure to apply
787    SQL markup on initial open.
788
789 3.  "Employees" example performance improvements when scrolling.
790
791 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
792    TFrame. Force recaching of selected frame to avoid GTK race (results in a
793    random image cached).
794
795 5.  DBControlGrid: Should now react to changes in panel height at run time.
796
797 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
798    even when further rows exist.
799
800 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
801    always be derived from panel height and setting this property can cause confusion.
802    Note for existing projects: to avoid a missing property error at run time,
803    each form using the DBControlGrid must be opened, updated and saved in the IDE
804    in order to remove the property value from the lfm.
805
806
807 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
808
809 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
810    call Prepare before setting parameter values.
811
812 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
813
814 3.  Code tidyup and more robust handling of dsql information result vector.
815
816 4.  Support for centralised handling of transaction status changes. TIBTransaction
817    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
818    and "AfterExecQuery". The first three are called after the same event is called
819    for an IBCustomDataSet descendent using the Transaction. The fourth is called
820    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
821    enable monitoring of transaction status changes for a given transaction to be
822    handled in a single place. For example, when a change to the dataset occurs
823    an indicator can be set that shows the user that in order to save changes,
824    the transaction should be committed.  Rather than doing this per dataset, this
825    can now be done per transaction.
826
827 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
828    the dataset is scrolled. However, any changes to the current row are, by default,
829    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
830    have a new property "DataSetCloseAction" that adds automatic posting of changes
831    on dataset close. If this property is set to dcDiscardChanges (default) then the
832    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
833    then IBX will attempt to post any unsaved changes before the dataset is closed
834    (and after the BeforeClose event handler is called). The exception is when the
835    dataset is being closed as a result of a transaction rollback. In this case,
836    no action is taken and any unsaved  changes are discarded. This avoids both
837    unnecessary overhead and the risk that a validation error may occur in the Post
838    raising an exception and thereby preventing a rollback.
839
840 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
841    In earlier versions, the Display Width was set to the maximum byte width rather than the character
842    width. Display Widths are now corrected by dividing by the max byte width per character.
843    For UTF8 character sets, the byte width is four and hence the Display Width will be
844    the byte width divided by 4. The byte width of each character set is determined
845    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
846    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
847
848 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
849
850 8.  IBLookupComboEditBox: List should now always be restored to full list when the
851    control loses focus. Default Key press default interval reduced to 200ms.
852
853 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
854    when dataset rows are less than visible rows.
855
856 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
857    does not exist or DataSet is empty. More responsive on dataset open. New event
858    OnRestorePosition. Column sort disabled if no header row.
859
860 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
861    while dataset state is dsInsert. Avoids posting errors.
862
863 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
864    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
865
866 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
867
868 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
869    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
870    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
871    always "posts" the current record regardless or whether or not it may be more appropriate
872    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
873    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
874    as the first action of the "Post" method and allows the handler to convert the Post
875    into a Cancel if that is the appropriate action on moving to a different row. This is
876    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
877    raised here, but it may still be more appropriate to validate a post and signal
878    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
879
880 15. On Unix derived systems, the Firebird library name can now be given as a colon
881    separated list. Each library name on the list is tried in turn, in left to right
882    order with the first found being used as the firebird library. By default, on Linux,
883    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
884    overidden by the FBLIB environment variable or the OnGetLibraryName function.
885
886    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
887    then it will still attempt to access the database via the Firebird Server and will
888    require a username and password. If only the pathname is given, then the username
889    and password should be omitted and the unix file permissions are used to grant
890    access.
891
892 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
893
894 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
895    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
896    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
897    corresponds to a row of the linked DataSource. Any data aware control on the
898    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
899
900 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
901   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
902   takes place during database access. This may be useful when there are performance issues with
903   the change of cursor. Setting the property to false suppresses the change of cursor.
904
905 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
906   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
907   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
908   making all changes permanent immediately rather than when the transaction is explicitly
909   committed.
910
911 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
912   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
913
914 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
915
916 Development version only.
917
918 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
919
920 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
921   This is typically used during an "OnBeforeOpen" event handler to manipulate the
922   "Where" and "Having" clauses to implement user specified filters of arbitrary
923   complexity.
924
925 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
926   three new data aware controls dependent on IBX and which make use of the SQL Parser.
927   These are:
928
929   - TIBLookupComboEditBox
930   - TIBDynamicGrid
931   - TIBTreeview
932
933   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
934   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
935   to revise the available list and restrict it to items that are prefixed by the
936   typed text (either case sensitive or case insensitive). Autoinsert allows a
937   newly typed entry to be added to the list dataset and included in the available
938   list items.
939
940   TIBDynamicGrid is a TDBGrid descendent that provides for:
941   - automatic resizing of selected columns to fill the available row length
942   - automatic positioning and sizing of a "totals" control, typically at the
943     column footer, on a per column basis.
944   - DataSet resorting on header row click, sorting the dataset by the selected column.
945     A second click on the same header cell reversed the sort order.
946   - Support for a "Panel Editor". That is on clicking the indicator column, the row
947     is automatically expanded and a panel superimposed on it. The panel can have any
948     number of child controls, typically data aware controls with the same datasource
949     as the grid allowing for editing of additional fields and more complex editors.
950   - Reselection of the same row following resorting.
951   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
952     Its properties are specified on a per column basis and allows for one or more
953     columns to have their values selected from a list provided by a dataset.
954     Autocomplete and autoinsert are also available. The existing picklist editor
955     is unaffected by the extension.
956
957   TIBTreeView is a data aware TCustomTreeView.
958
959 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
960   zero scale will no longer return an error. An Int64 will be returned instead.
961
962 4. TIBTransaction now has events for Before and After Transaction End and a new function
963   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
964
965 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
966   repeated multiple times.
967
968 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
969   check used to get in the way of using Stored Procedures, and "Update or Insert"
970   statements.
971
972 7. Insert, Modify and Delete property Editors now support Query Generation from
973   Stored Procedures.
974
975 8. Three new examples illustrate the use of the new IB Controls
976
977
978 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
979
980 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
981   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
982   Gabor Boros for reporting this problem and for testing the improvements).
983
984 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
985   See readme.field+param.names in the doc folder.
986
987 3. IBX SQL Editors will now automatically add double quotes around column names when the database
988   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
989
990 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
991
992 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
993   actions.
994
995 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
996   thanks to Yuriy Kopnin for pointing this out).
997
998 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
999
1000 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1001   for both fields and parameter setting.
1002
1003 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1004   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1005
1006 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1007    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1008
1009 11. TIBTable now has a property editor for "MasterFields"
1010
1011 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1012    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.

1014 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination

1024 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1025   it is null. This allows for alternative user defined setting of the generator
1026
1027   Many thanks to Julio Jiménez for this fix
1028
1029 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1030   and suggests that the user may have forgotten to install it.

1036

1048
1049 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1050   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1051
1052 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1053   package is changed to do this (which it should do).
1054

1056
1057 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1058
1059 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1060
1061 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1062
1063 4. Property editors should now correctly resize.
1064
1065 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1066   (restored original functionality)
1067
1068 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1069   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
