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 deLaoutChanged 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 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
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 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 RELEASE.
85  
107 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
86  
87 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
112 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
113 <   information). However, this is also a very useful mechanism for returning updated computed by
114 <   column values. Values returned as a result of executing an Insert or Update statement
115 <   replace existing values in the current row for each corresponding column.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 <   Previously, if a dataset's select query included read only (computed by) fields then
92 <   an automatic row refresh was performed after an insert or update query had been processed,
119 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
120 <   that an automatic refresh is no longer performed if an insert or update query contains
121 <   a returning clause that updates one or more fields on the current row. A full row
122 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
123 <   field values and the select query contains read only fields. Use of Insert/update
124 <   returning should be significantly more efficient than executing a refresh query.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 <   This behaviour change is intended to be backwards compatible and there should be no need to change
95 <   existing programs, other than to improve performance by using the new capability.
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 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
99 <   they are called when the dataset row is being deleted, there is no value in
131 <   updating the current record from the query result. Instead, a new event handler
132 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
133 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
134 <   by the query. The event handler can then interrogate the query results and
135 <   perform whatever action is necessary. For example to confirm, to the user,
136 <   the deletion of a row with the returned values.
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 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
139 <   any Computed By or Identity Columns. The IBTables example has been updated to
140 <   illustrate the computation of the employee Full Name on update.
101 > 5. New function added to IB.pas
102  
103 < 5. TIBTable: The GeneratorField property is now published.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
106 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
107 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
108 <   each Identity column after the insert is executed.
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 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
150 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
151 <   Insert..Returning clause.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 8. TIBGenerator: small performance improvement by not preparing query each time
113 <   a new value is generated.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 10. Property editors will now sync table name to a System Table when "Include System
120 <    Tables" is selected and the query is for a System Table.
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 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
125 <    values are no longer converted to milliseconds from TDateTime and then back again
163 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 12. Property Editors handling of Stored Procedures.
128 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
129 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
168 <      query).
169 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
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 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
132 <    can be used to select a package. If non-empty, the stored procedure name is
173 <    expected to be a stored procedure defined in the specified package and the
174 <    generated SQL will be as required for a stored procedure located in a package.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
135 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
178 <    which a stored procedure can be selected. With no package name selected, non-package
179 <    stored procedures are listed.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182 <    for password on reconnect.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < 16. TIBDatabase: use IAttachment for connection default character set id, code page
185 <    and character set name.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
188 <    DB info lookups"
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
192 19. Add a property Editor for TIBUpdate.RefreshSQL.
145  
146 < 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
195 <    parameters. This stops an exception being raised when the field cannot be
196 <    located in the record buffer.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 21. Property Editors now automatically include System Tables when opened and when the query table
199 <    is a System Table.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
151 <    This avoids errors due to a stale SQRB or SRB being used for the next query.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 23. IBServices: Service attach parameters now include "expected_db". This is used to
155 <    add the SPB item isc_spb_expected_db. This names a database using
156 <    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
157 <    database. examples/services re-written to illustrate use of "expected_db".
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 < 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
210 <    This avoids truncated backups when the server returns a timeout (busy) response.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
164 <    databasenames. These are respectively expanded to the local system's temp directory
165 <    (including trailing delimiter) or to a prescribed data directory (including
166 <    trailing delimiter). Under Unix systems the data directory is a hidden directory
167 <    in the user's home directory. The hidden directory name is either the string returned
219 <    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220 <    Under Windows, the directory is the same as the Data Directory as decribed
221 <    above but instead prefixed by the User's application data path. These may be
222 <    used to improve application portability for Personal Databases.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
170 <    this has not worked for a long time and is not useful either. FieldDefs should be
226 <    managed using the Fields Editor as with any other dataset. To access the fields
227 <    editor for a TIBTable component, double click on the component. The fields editor
228 <    is then displayed.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 28. TIBDatabaseInfo: new properties/function
173 <     * DateDBCreated (returns date/time database created)
232 <     * TransactionCount (returns no. of active transactions)
233 <     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
234 <     * PagesFree (Firebird 3 or later)
235 <     * PagesUsed (Firebird 3 or later)
236 <     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
237 <     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
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 < 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
244 <    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
183 > 9. IBUtils code tidy up.
184  
185 < 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
186 <    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
187 <    firing during backup and restore.
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 < 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
251 <    for verbose output using the new property "StatisticsRequested".
252 <    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 < 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
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 < 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
198 <    palette. This uses the online validation feature added in Firebird 2.5. The
258 <    services's properties enable inclusion/exclusion of tables and indexes using
259 <    regular expressions. See.
260 <    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
201 <    option on a database.
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 < 37. TIBCustomService: Assign method implemented to allow copying of service login
204 <    context between service API components. "Detach" method now only detaches
205 <    service when last reference to the service interface detaches. Tidy up of
268 <    code for SetActive and Attach methods including password hiding.
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 < 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
271 <    and used to determine the auth method and protocol used for the connection.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
208  
209 < 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
210 <    a Create Database Statement generated by IBX.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 < 40. All IBServices now have an additional published property "PortNo". This may
213 <    be set to a non-standard port number when necessary. If zero then the default
214 <    port number is used.
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 < 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
218 <    and not just the mouse.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
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 < 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
226 <    image index and selected image index for each node to be set from a database field.
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 < 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
231 <    then database schema includes grants to all users. If not present then the
290 <    only user grants included are those to User PUBLIC.
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 < 45. TIBTreeView: performance improvement. When expanding include both expanded node
234 <    and child nodes in dataset.
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 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
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 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
299 <   changes.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
302 <   Bug could result in truncated multi-byte character set values.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 3. Changes consequential on moving fbintf character set utility functions from
305 <   IFirebirdAPI to IAttachment.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
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 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
310 <   results in autocomplete ignoring prefix text.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
257 <   entering a new name into the text box.
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 < 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
260 <   Firebird rather than recomputing it.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
318 8. Property Editor positioning tidy up: All IBX Property editors should now be
319   screen centre. Previously some were "poDesigned" which may be inappropriate
320   for multi monitor desktops.
262  
263 < 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
325 <    a transaction and always reset the object.
265 > 1. Change syntax to Mode Delphi
266  
267 < 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < 13. TIBXScript: Allow for override of database filename in Create Database statements.
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
332 <    to a gbak format archive.
273 > 4. Generics syntax variations for Delphi added
274  
275 < 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 16. IBLocaldb: Drop database if error creating an empty database.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
339 <    unless selected node not in current dataset.
280 > 7. Testsuite updated for Delphi
281  
282 < 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
342 <    to TIBCustomService, and IBlocalDB code tidy up.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 < 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
285 <    behaviour due to uninitialised variable.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
288 <    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 21. IBSQL: When Database changed ensure that all resources are freed.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 22. IBCustomDataset: When database changed ensure that queries an unprepared.
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 < 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
355 <    * Line Wrap on SQL Token boundaries (on user command)
356 <    * auto-complete table names in drop down list of table names
357 <    * Double click on tablename or field name adds to SQL text
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
302 <    TVariantArray. Seems to avoid memory corruption in Windows (probably a
363 <    workaround for a problem in fpc 3.0.4 win64).
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
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 < 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
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 < IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
310 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 >    to enable stats gathering.
313  
314 < 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
372 <   include remote system name.
314 > 11. API Version information added as constants to IB.pas
315  
316 < 2. TIBExtract: No longer include comment header and COMMIT statement for empty
375 <   tables when data included in output.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
378 <   and timing information to be written to stdout. This may be used to locate
379 <   performance bottlenecks.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 4. SQLParser: only call "OnChanging" event handler when value is different.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
322 > 1. Initial Release
323  
385 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
386   that BindFields is called when the query is next activated. Avoids FieldName
387   not found error.
388
389 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
390   purpose and allows the programmer to define any action they want for Update, Insert
391   or Delete. This may be complex SQL (similar to a Trigger), application specific
392   filtering of updates, or use of statements such as Grant or Revoke instead of
393   normal DML. See User Manual for more information.
394
395 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
396
397 1. TIBEvents: Fix uninitialised variable that could result in lost events.
398
399 2. TIBExtract: Added support for FB3 "USAGE" privilege.
400
401 3. TIBExtract: data formatted as Charset set "octets" is now output using
402   hexadecimal notation.
403
404 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
405   using a simple XML format.
406
407 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
408   grants to these objects.
409
410 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
411   dependency problems restoring complex databases.
412
413 7. TIBXScript: This component has been restructured to allow for the processing of
414   embedded XML in INSERT statements and to support interactive sources in addition
415   to non-interactive data sources such as files.
416
417 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
418
419 9. TIBXScript: ISQL compatiable Set statements are now supported:
420   SET SQL DIALECT
421   SET TERM
422   SET AUTODDL
423   SET BAIL
424   SET ECHO
425   SET COUNT
426   SET STATS
427   SET NAMES <character set>
428
429 10. IBVersion unit added to hold current IBX Version Number information.
430
431 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
432    and domain definitions.
433
434 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
435    fully supported.
436
437 13. TIBExtract: when a database dump includes data, the generator values are now also set.
438
439 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
440
441 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
442
443 See also doc/IBX4LazarusGuide.pdf for important information on
444 upgrading to IBX2.
445
446 1. Size property of TIBStringField is now the width in characters of the field
447   and not the byte length. This applies only to multi-byte character sets such
448   as UTF8. The original approach aligned with TStringField. However, the TStringField
449   code is not recognised as a bug and hence this change to align the behaviour.
450   The TStringField change is expected in fpc 3.2.0.
451
452 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
453   true (default) then Size property value saved in the lfm is ignored. Size is
454   always set from the dynamic information read from the database. It is unclear
455   why anyone would want to override this and set Size to false.
456
457 3. ibxscript: should now handle correctly a Case..End statement within a procedure
458   block.
459
460 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
461   exist when an attempt is made to connect to it (run time only) then an attempt
462   is made to create the database.
463
464 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
465   has been successfully created as a result of a call to CreateDatabase or when
466   creating a database after it was found not to exist.
467
468 6.  DBControlGrid: a race condition could result in the wrong row image being
469    written to the cache. This has been avoided by a trip round the message
470    loop before rendering the row image.
471
472 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
473    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
474    known to risk corrupt rendering of row images when the control is first
475    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
476    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
477
478 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
479    a TDateEdit control located on an editor panel.
480
481 9.  TIBExtract: brought up-to-date plus many bug fixes.
482
483 10. DBControlGrid: Removed memory leak when updating rows.
484
485 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

487 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
488
489 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
490   when target codepage is CP_NONE. This is a workaround for
491   http://bugs.freepascal.org/view.php?id=30622.
492
493 2. DBLog option removed from TIBStatisticalService - not supported by server
494   since Firebird 1.5.
495
496 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
497   similar.
498
499 4. IBCodePage: updated mapping between codepages and character id.
500
501 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
502   Firebird. Character sets with a char width of two are not UTF16.
503
504 6. Strings received from the database are now always transliterated into UTF8
505   regardless of the database character set or connection character set. This
506   is for compatibility with the LCL.
507
508 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
509
510 1. IBBlob: Defer reading of blob until read method called. This avoids having to
511   read in an entire blob just to get the size of the blob. General performance
512   improvement when opening datasets containing blobs.
513
514 2. Clearing a  Blob now sets the corresponding field's modified flag.
515
516 3. IBLookupCombo: When not performing auto-complete, original query sort order
517   is now used.
518
519 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
520   determined.
521
522 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
523
524 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
525   lazarus 1.6.0
526
527 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
528   compilation error.
529
530 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
531
532 1. No character set specified for connection: when a text blob is retrieved, the
533  character set is determined by looking up the native character set using then
534  Firebird API. Otherwise a text mode blob is assumed to have the same character
535  set as the connection.
536
537 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
538   for Login Dialog returing a change to the database path.
539
540 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
541   to be changed from that given in the TIBDatabase/TIBServer component and for the
542   entered value to be saved on a project specific basis (design time only).
543
544 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
545   column fieldname. If they are the same then it is acts as a look up for the KeyValue
546   Otherwise, it sets the column text to the selected ListField Value.
547
548 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
549   column width.
550
551 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
552   and a case insensitive search is requested.
553
554 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
555   or column ListSource.
556
557 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
558   unprepare) when closing and the text has not changed.
559
560 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
561   Less likely to cause a cursor re-use error on Windows.
562
563 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
564   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
565
566 11. TIBTreeView: Guard against nil destination on record changed
567
568 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
569    string type with the code page set to reflect the returned field encoding after
570    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
571    earlier versions.
572
573 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
574    will now result in transliteration to the code page specified for the Firebird driver
575    if the assigned string has a different code page. FPC 3.0.0 onwards only.
576
577 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
578    is ignored and the lc_ctype value, when the database is opened, is set to align with
579    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
580    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
581    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
582    the GETACP is used to determine the Windows code page.
583
584 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
585    name used as the lc_ctype when the database was opened. Only valid while the
586    Database is connected.
587
588 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
589    id that corresponds to the DefaultCharSetName.
590
591 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
592
593 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
594   path is given and database attach fails due to access permission issues on the
595   temp directory or security database, then the attach is retried with "localhost:"
596   prefixing the databasename. This should avoid problems when the database has to
597   be accessed by a local (e.g. classic) server and libfbembed is used.
598
599 2. Windows: revised search order for Firebird DLL:
600     i.   The Firebird Embedded Server in the application Directory.
601     ii.  If the FIREBIRD environment variable is set then the directory this
602          points to is searched for the FB Client DLL and then then underlying
603          "bin" directory.
604     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
605          is used to locate the Firebird installation directory and the underlying
606          "bin" directory is searched for the FB Client DLL.
607     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
608          are searched for the FB Client DLL.
609     v.   The PATH Environment variable is used to search for the FB Client DLL.
610     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
611
612 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
613   See doc/readme.scriptengine and example applications.
614
615 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
616   simplify the use of the embedded firebird server on both Linux and Windows platforms.
617   See dpc/readme.localdatabase and example applications.
618
619 5. IBDynamicGrid: Reordering on column header click should now also work for
620   dynamic columns.
621
622 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
623   between incrementing/decrementing the lock count and signalling the event.
624
625 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
626
627 1.3.2 was never formally released and only made available as beta copies.
628
629 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
630
631 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
632
633 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
634
635 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
636   i.e. when it is a calculated field
637
638 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
639   This problem was due to a race condition between recalculating row heights and
640   determining which row was selected by the mouse click. The row height calculation
641   is now deferred by an extra trip round the message loop allowing the row to
642   be always calculated on the current grid layout rather than risking it being
643   calculated on the grid layout after the expanded row has been shrunk.
644
645 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
646   Windows.
647
648 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
649   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
650   to be determined at runtime. See doc/readme.charactersets.html.
651
652 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
653   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
654
655 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
656   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
657   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
658
659   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
660   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
661   implies no truncation.
662
663 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
664
665 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
666   (avoids "Not in Edit Mode" error).
667
668 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
669
670 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
671    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
672
673 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
674
675 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
676
677 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
678
679 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
680
681 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
682
683 1.   OnCloseUp Event Handler added to TDBLookupProperties
684
685 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
686     problem with row size when exception is called.
687
688 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
689
690 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
691     in a TCustomComboBox and ignores return key if in a TCustomMemo
692
693 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
694     keyed in i.e. when autocomplete not performed
695
696 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
697     console mode applications with all LCL required functions (builtin dialogs and
698     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
699     not included in your project, IBX should compile and link with a console mode program.
700     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
701     console mode application or the IDE will automatically assume that your
702     application is GUI based. Instead, you should include the ibexpressconsolemode package.
703
704     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
705     to use the built in dialogs and cursor management. IBDialogs is
706     included by default if "ibexpress" is in your project source's "uses" clause.
707     This should be the case for all projects created through the IDE. This is why
708     you do not want to add the ibexpress package to console mode applications. The
709     ibexpressconsolemode package has been created to allow console mode programs
710     to avoid adding LCL dependencies when using IBX, while still having the
711     unit search paths set up correctly.
712
713     Existing users should check to ensure that the "ibexpress" unit is included in
714     each project's source file (*.lpr).
715
716     You may find that in order for the IDE to recognise that ibexpressconsolemode
717     exists, you have to first open the package in the IDE and then close it. This
718     adds it to the most recently accessed packages list. To make it permanently
719     available, add the package name to lazarus' staticpackages.inc file.
720
721         Thanks to Julio Jiménez for suggesting support of console mode.
722
723 7.   SQL Parser can now accept quoted strings that include new lines
724
725 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
726     of text on start of edit. This is particularly useful when tabbing to a
727     column and then inserting text.
728
729 9.   New Examples provided for IB Services and ISQLMonitor.
730
731 10. Fix error when writing to blob streams that recorded only the last buffer
732    write in the blob stream. In most cases, this did not cause a problem as the
733    IB Blob Stream is written in a single write. However, with the TDBImage, write
734    of a graphic type prefix was lost which caused a problem when the image could
735        not be automatically recognised.
736
737 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
738    already open" errors due to random numbers used for the cursor name being identical.
739
740 12. IBTable: corrected error that could result in an "Index out of bounds" error
741    when opening the table and the Primary Key is the last or only column in the
742    table. Thanks to Rick Hoover for the fix.
743
744 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
745    of "UTF-8", and update list of available database character sets. Existing
746    users should check the current lc_ctype setting in their applications.
747
748 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
749
750 1.  Firebird Services: avoid List Index error when opening a service with an
751    empty Params property.
752
753 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
754    Link now set up in Loaded method - avoids occasional failure to apply
755    SQL markup on initial open.
756
757 3.  "Employees" example performance improvements when scrolling.
758
759 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
760    TFrame. Force recaching of selected frame to avoid GTK race (results in a
761    random image cached).
762
763 5.  DBControlGrid: Should now react to changes in panel height at run time.
764
765 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
766    even when further rows exist.
767
768 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
769    always be derived from panel height and setting this property can cause confusion.
770    Note for existing projects: to avoid a missing property error at run time,
771    each form using the DBControlGrid must be opened, updated and saved in the IDE
772    in order to remove the property value from the lfm.
773
774
775 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
776
777 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
778    call Prepare before setting parameter values.
779
780 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
781
782 3.  Code tidyup and more robust handling of dsql information result vector.
783
784 4.  Support for centralised handling of transaction status changes. TIBTransaction
785    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
786    and "AfterExecQuery". The first three are called after the same event is called
787    for an IBCustomDataSet descendent using the Transaction. The fourth is called
788    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
789    enable monitoring of transaction status changes for a given transaction to be
790    handled in a single place. For example, when a change to the dataset occurs
791    an indicator can be set that shows the user that in order to save changes,
792    the transaction should be committed.  Rather than doing this per dataset, this
793    can now be done per transaction.
794
795 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
796    the dataset is scrolled. However, any changes to the current row are, by default,
797    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
798    have a new property "DataSetCloseAction" that adds automatic posting of changes
799    on dataset close. If this property is set to dcDiscardChanges (default) then the
800    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
801    then IBX will attempt to post any unsaved changes before the dataset is closed
802    (and after the BeforeClose event handler is called). The exception is when the
803    dataset is being closed as a result of a transaction rollback. In this case,
804    no action is taken and any unsaved  changes are discarded. This avoids both
805    unnecessary overhead and the risk that a validation error may occur in the Post
806    raising an exception and thereby preventing a rollback.
807
808 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
809    In earlier versions, the Display Width was set to the maximum byte width rather than the character
810    width. Display Widths are now corrected by dividing by the max byte width per character.
811    For UTF8 character sets, the byte width is four and hence the Display Width will be
812    the byte width divided by 4. The byte width of each character set is determined
813    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
814    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
815
816 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
817
818 8.  IBLookupComboEditBox: List should now always be restored to full list when the
819    control loses focus. Default Key press default interval reduced to 200ms.
820
821 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
822    when dataset rows are less than visible rows.
823
824 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
825    does not exist or DataSet is empty. More responsive on dataset open. New event
826    OnRestorePosition. Column sort disabled if no header row.
827
828 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
829    while dataset state is dsInsert. Avoids posting errors.
830
831 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
832    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
833
834 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
835
836 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
837    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
838    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
839    always "posts" the current record regardless or whether or not it may be more appropriate
840    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
841    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
842    as the first action of the "Post" method and allows the handler to convert the Post
843    into a Cancel if that is the appropriate action on moving to a different row. This is
844    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
845    raised here, but it may still be more appropriate to validate a post and signal
846    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
847
848 15. On Unix derived systems, the Firebird library name can now be given as a colon
849    separated list. Each library name on the list is tried in turn, in left to right
850    order with the first found being used as the firebird library. By default, on Linux,
851    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
852    overidden by the FBLIB environment variable or the OnGetLibraryName function.
853
854    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
855    then it will still attempt to access the database via the Firebird Server and will
856    require a username and password. If only the pathname is given, then the username
857    and password should be omitted and the unix file permissions are used to grant
858    access.
859
860 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
861
862 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
863    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
864    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
865    corresponds to a row of the linked DataSource. Any data aware control on the
866    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
867
868 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
869   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
870   takes place during database access. This may be useful when there are performance issues with
871   the change of cursor. Setting the property to false suppresses the change of cursor.
872
873 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
874   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
875   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
876   making all changes permanent immediately rather than when the transaction is explicitly
877   committed.
878
879 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
880   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
881
882 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
883
884 Development version only.
885
886 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
887
888 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
889   This is typically used during an "OnBeforeOpen" event handler to manipulate the
890   "Where" and "Having" clauses to implement user specified filters of arbitrary
891   complexity.
892
893 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
894   three new data aware controls dependent on IBX and which make use of the SQL Parser.
895   These are:
896
897   - TIBLookupComboEditBox
898   - TIBDynamicGrid
899   - TIBTreeview
900
901   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
902   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
903   to revise the available list and restrict it to items that are prefixed by the
904   typed text (either case sensitive or case insensitive). Autoinsert allows a
905   newly typed entry to be added to the list dataset and included in the available
906   list items.
907
908   TIBDynamicGrid is a TDBGrid descendent that provides for:
909   - automatic resizing of selected columns to fill the available row length
910   - automatic positioning and sizing of a "totals" control, typically at the
911     column footer, on a per column basis.
912   - DataSet resorting on header row click, sorting the dataset by the selected column.
913     A second click on the same header cell reversed the sort order.
914   - Support for a "Panel Editor". That is on clicking the indicator column, the row
915     is automatically expanded and a panel superimposed on it. The panel can have any
916     number of child controls, typically data aware controls with the same datasource
917     as the grid allowing for editing of additional fields and more complex editors.
918   - Reselection of the same row following resorting.
919   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
920     Its properties are specified on a per column basis and allows for one or more
921     columns to have their values selected from a list provided by a dataset.
922     Autocomplete and autoinsert are also available. The existing picklist editor
923     is unaffected by the extension.
924
925   TIBTreeView is a data aware TCustomTreeView.
926
927 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
928   zero scale will no longer return an error. An Int64 will be returned instead.
929
930 4. TIBTransaction now has events for Before and After Transaction End and a new function
931   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
932
933 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
934   repeated multiple times.
935
936 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
937   check used to get in the way of using Stored Procedures, and "Update or Insert"
938   statements.
939
940 7. Insert, Modify and Delete property Editors now support Query Generation from
941   Stored Procedures.
942
943 8. Three new examples illustrate the use of the new IB Controls
944
945
946 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
947
948 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
949   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
950   Gabor Boros for reporting this problem and for testing the improvements).
951
952 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
953   See readme.field+param.names in the doc folder.
954
955 3. IBX SQL Editors will now automatically add double quotes around column names when the database
956   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
957
958 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
959
960 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
961   actions.
962
963 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
964   thanks to Yuriy Kopnin for pointing this out).
965
966 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
967
968 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
969   for both fields and parameter setting.
970
971 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
972   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
973
974 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
975    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
976
977 11. TIBTable now has a property editor for "MasterFields"
978
979 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
980    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
981
982 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
983    of settings is unrecognised. Selecting this radio button has no effect on the settings.
984

989
990 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
991
992 1. In a TIBCustomDataset descendent, a generator now only sets the value when
993   it is null. This allows for alternative user defined setting of the generator
994
995   Many thanks to Julio Jiménez for this fix
996
997 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
998   and suggests that the user may have forgotten to install it.
999
1000 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1001
1002 1. Conditional compilation used to limit registration of TIntegerField to
1003   Lazarus versions less than 1.1
1004
1005 2. When a database connection is created, character set is now by default set
1006   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1007   1250 to 1254.
1008

1015 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1016
1017 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1018   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1019
1020 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1021   package is changed to do this (which it should do).
1022
1023 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1024
1025 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1026
1027 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1028
1029 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1030
1031 4. Property editors should now correctly resize.
1032
1033 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1034   (restored original functionality)
1035
1036 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1037   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
