8 > 3. New API Calls:
9 >        IColumnMetaData.GetStatement
10 >        IColumnMetaData.GetTransaction
11 >        ISQLData.GetStrLength
12 >        IResults.GetStatement
13 >        IAttachment.OpenBlob (using Blob metadata)
14 >        IAttachment.OpenArray (using array metadata)
15  
16 < IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
10 < all previous copies of the IBX source code tree before installing this release.
16 > 4. FBMessages: removal of unused messages
17  
18 < The IBX packages used by most users have not changed, with one exception. The
13 < IBServices unit has been moved to the package iblegacyServices.lpk. To continue
14 < to use the IBServices unit in your applications, please add the iblegacyServices
15 < to the list of dependencies. To do this, open the Project Inspector and select
16 < Add->New Requirement and select "ibLegacyServices" from the list of available
17 < packages.
18 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19  
20 < 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
20 <   the IBServices unit providing what is intended to be a clearer and easier to
21 <   use set of IB Services components. See Chapter 10 of the IBX User Guide for
22 <   more information and the guide to "Firebird Service Management Using IBX".
23 <   As indicated above, the legacy services components are still available and
24 <   provided in a separate package. There is no need to update working applications
25 <   using the older versions except for an additional package dependency.
20 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21  
22 < 2. The IBX packages and source code tree have been re-organised in an attempt to
28 <   finally get rid of the "duplicate ppu" warnings. This re-organisation should
29 <   not affect existing users. Section 2.3 of the IBX User Guide describes the
30 <   new set of IBX packages.
22 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23  
24 < 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
25 <   updated to use the new Services API components.
24 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 >   where the second character of the parameter name is a numeric.
26  
27 < 4. The iblocal package has been updated to use the new Services API components.
27 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 >   This returns the isc_version connection information as one or more lines.
29 >   This is the same information as returned by isql with the -z option.
30  
31 < 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
40 <   correctly positioned as part of the Security Package. In the DBAdmin example,
41 <   the setting has moved to the mappings page.
31 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 >   compiler option then the Firebird 3 API is no longer compiled in.
34  
35 < 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
44 <   are ignored.
35 > 4. IColumnMetaData: new method.
36  
37 < 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
38 <   closed before the database is dropped. Before and After Disconnect event handlers
39 <   are also fired.
37 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 >                        dfDateTime,   {SQL DATETIME}
39 >                        dfTime);
40  
41 < 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
51 <   is started and not just the first time.
41 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42  
43 < 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
44 <   depenendency with comp type.
43 >   This returns the max. number of characters returned by the "AsString" method
44 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45  
46 < 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
46 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 >     CaseSensitiveParams: boolean = false
48  
49 < 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
50 <    then this is recognised and not ignored.
49 >   If this argument is set to true then SQL parameter names are assumed to be case
50 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
51 >   sensitive name.
52  
53 < 12. TIBDataSet, TIBQuery, TIBTable: additions:
54 <    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
55 <    function GetPerfStatistics(var stats: TPerfCounters): boolean;
56 <    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
53 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
56 >   using .AsString.
57  
66    GetRowsAffected returns the affected row counts from the last insert/update/delete
67    if EnableStatistics = true then GetPerfStatistics returns the current stats
68    counters for the select query. Note: stats accumulate after each fetch from
69    the database. To get total query cost after open, call the "Last" method
70    and then GetPerfStatistics.
58  
72    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
59  
60 < 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
75 <    in parenthesises.
60 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61  
62 < 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
78 <    SQL identifiers are always delimited by double quotes. If false, then they are
79 <    only delimited if the identifier is a reserved word, contains lower case or special
80 <    characters. Set this property to true to retain previous behaviour.
62 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63  
64 < 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
65 <    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
64 > 2. Restrict IsMultiThread check to Unix only for compatibility with
65 >   https://bugs.freepascal.org/view.php?id=30535
66  
67 < 16. TIBDataSet, TIBQuery, TIBTable: addition:
68 <       property MasterDetailDelay: integer {defaults to zero}
67 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
69 >   and processing internal parameters as statement parameters.
70  
71 <    When non-zero and the dataset is a detail table referencing a master table
72 <    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
90 <    then a synchronisation delay is added (in milliseconds) between the master
91 <    row changing and the detail dataset being re-opened. If the master dataset
92 <    is scrolled before the delay expires then the delay is reset. This can be used
93 <    to avoid performance overheads when scrolling through a large master dataset.
71 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73  
74 <    Note: uses fptimer and hence requires a thread manager. Under Linux the
96 <    chreads unit must be included in your project. TTimer is not used in order
97 <    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
74 > 5. New function added to IB.pas
75  
76 < 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
100 <    with Extract Option eoDatabase.
76 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77  
78 < 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
79 <    When a deLayoutChanged event is reported on the ListSource dataset, the
80 <    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
81 <    relationship with the control's datasource (master).
78 >   This allows a Firebird Library to be loaded from an explicit path. use the
79 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 >   the library. It is possible to load Firebird libraries from different locations
81 >   simultaneously, each with a distinct IFirebirdAPI.
82  
83 < 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
83 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84  
85 < 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
86 <    stubs. Pedantic fix really, as procedures output in dependency order anyway.
85 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 >   program compiled with -CR command line switch.
87  
88 < 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
89 <    DDL (Firebird 3 and later only).
88 > 2. IServiceManager additions (informational):
89 >    function getProtocol: TProtocol;
90 >    function getPortNo: AnsiString;
91  
92 < 22. TIBLookupComboBox Autocomplete Fixes:
93 <    i. Only appended text is now selected after autocomplete.
94 <    ii. Uppercase keys no longer ignored for autocomplete.
95 <    iii. Retain Prefix case is now honoured correctly.
119 <    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
120 <        before autocomplete performed. i.e. behaviour now the same as when
121 <        no DataSource assigned.
92 > 3. IServiceManager improved error handling. Interfaces changed:
93 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96  
97 < 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
98 <    between SQL statements.
97 > 4. IAttachment addition (informational)
98 >    function GetSecurityDatabase: AnsiString;
99  
100 < 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
101 <    ObjectNames are converted to upper case before matching against metadata object
102 <    names, unless the objectname is delimited by double quotes, in which case, the
129 <    double quotes are removed and the remaining string is used (unmodified) to match
130 <    against the metadata object name.
100 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 >   thus now returns accumulated stats for a select statement from opening a cursor
102 >   up to the last fetch.
103  
104 <    If true then the ObjectName is used as is without modification and matched
105 <    against the metadata object name. No attempt is made to remove double quotes.
104 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 >   the problem.
106  
107 < 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
108 <    with eoTrigger, these extract types can be used to select only Database Triggers,
137 <    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
107 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 >   replaces deprecated "comp" type.
109  
110 < 26. TIBXScript: If an exception occurs during the processing of a statement, the
140 <    statement separate character is now reset to the default (';').
110 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111  
112 < 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
112 > 11. URL Connection Strings: inet4 and inet6 now recognised.
113  
114 < 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
145 <    a commit or reconnect statement and instead activated only when next SQL statement
146 <    is executed.
114 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115  
116 < 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
116 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117  
150 30. TIBXScript: case insensitive regex now used when matching statements instead of
151    converting statement to upper case.
118  
119 < 31. TIBExtract: metadata comments now supported. New published property
154 <    IncludeMetaDataComments (default true). If true then metadata comments included
155 <    in extracted DDL. New Extract Object member eoComments. This may be used with
156 <    ExtractObject method to list all metadata comments.
119 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120  
121 < 32. TIBExtract: ListObjectNames method added.
121 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122  
123 < 33. Updated Database component editor to support additional connection string
124 <    types.
123 > 2. IAttachment: add two new methods
124 >     function HasDefaultCharSet: boolean;
125 >     function GetDefaultCharSetID: integer;
126  
127 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
127 >   These return, respectively, true if a connection default character set was
128 >   specified and the character set id of the connection default character set.
129 >   The DefaultCharSetID is cached when the connection is opened and hence does not
130 >   require a database lookup.
131  
132 < NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
166 < AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
167 < RELEASE.
132 > 3. Avoid exception when a text blob is a stored procedure parameter.
133  
134 < NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
134 > 4. Update test suite to include a test for a stored proc returning a text blob.
135  
136 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
136 > 5. IAttachment: add
137 >      function GetRemoteProtocol: AnsiString;
138 >      function GetODSMajorVersion: integer;
139 >      function GetODSMinorVersion: integer;
140 >      function GetAuthenticationMethod: AnsiString;
141  
142 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
143 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
175 <   information). However, this is also a very useful mechanism for returning updated computed by
176 <   column values. Values returned as a result of executing an Insert or Update statement
177 <   replace existing values in the current row for each corresponding column.
142 >   These results are cached when the connection is opened and hence do not
143 >   require a database lookup.
144  
145 <   Previously, if a dataset's select query included read only (computed by) fields then
146 <   an automatic row refresh was performed after an insert or update query had been processed,
181 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
182 <   that an automatic refresh is no longer performed if an insert or update query contains
183 <   a returning clause that updates one or more fields on the current row. A full row
184 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
185 <   field values and the select query contains read only fields. Use of Insert/update
186 <   returning should be significantly more efficient than executing a refresh query.
145 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 >   connect string used to create/connect to the database.
147  
148 <   This behaviour change is intended to be backwards compatible and there should be no need to change
149 <   existing programs, other than to improve performance by using the new capability.
148 > 7. IAttachment: Create Database using SQL statement. The username and password
149 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 >   It is now possible to use IAttachment disconnect/connect to reconnect to
151 >   a database for which the initial connection was established by a create
152 >   database sql statement. Available in FPC only.
153  
154 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
192 <   they are called when the dataset row is being deleted, there is no value in
193 <   updating the current record from the query result. Instead, a new event handler
194 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
195 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
196 <   by the query. The event handler can then interrogate the query results and
197 <   perform whatever action is necessary. For example to confirm, to the user,
198 <   the deletion of a row with the returned values.
154 > 8. Update Test 1 to test 5, 6 and 7 above.
155  
156 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
201 <   any Computed By or Identity Columns. The IBTables example has been updated to
202 <   illustrate the computation of the employee Full Name on update.
156 > 9. IBUtils code tidy up.
157  
158 < 5. TIBTable: The GeneratorField property is now published.
158 > 10. Parameter Block interfaces "find" method. As documented, this should have
159 >   returned a nil interface when the item could not be found. Instead, an empty
160 >   interface item was returned. "Find" now works as documented and will return
161 >   a nil interface if the item cannot be found.
162  
163 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
207 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
208 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
209 <   each Identity column after the insert is executed.
163 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164  
165 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
166 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
167 <   Insert..Returning clause.
165 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 >    requests with additional parameters. This is to enable support for fb_info_page_contents
167 >    (return of page contents). Response to fb_info_page_contents returned as
168 >    a string with code page CP_NONE.
169  
170 < 8. TIBGenerator: small performance improvement by not preparing query each time
171 <   a new value is generated.
170 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 >    test suite updated.
172  
173 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
173 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175  
176 < 10. Property editors will now sync table name to a System Table when "Include System
177 <    Tables" is selected and the query is for a System Table.
176 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 >    default connection port to be specified.
179  
180 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
224 <    values are no longer converted to milliseconds from TDateTime and then back again
225 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
180 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181  
182 < 12. Property Editors handling of Stored Procedures.
183 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
229 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
230 <      query).
231 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
182 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 >   Scale is no longer ignored.
184  
185 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
186 <    can be used to select a package. If non-empty, the stored procedure name is
187 <    expected to be a stored procedure defined in the specified package and the
188 <    generated SQL will be as required for a stored procedure located in a package.
185 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 >   not in locale format but which are recognised by Firebird. Date values that
187 >   cannot be converted to a string using Pascal library are now passed through
188 >   to Firebird as Text Strings.
189  
190 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
191 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
240 <    which a stored procedure can be selected. With no package name selected, non-package
241 <    stored procedures are listed.
190 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 >   UTF8 and not UNICODE_FSS.
192  
193 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
194 <    for password on reconnect.
193 > 4. Charset ID problem. When using Firebird 3, with no default database character set
194 >   and a column has a non-default collation specified, an incorrect character set
195 >   id was being reported that could result in a 'division by zero' error when
196 >   used by IBX. This has now been fixed.
197  
198 < 16. TIBDatabase: use IAttachment for connection default character set id, code page
199 <    and character set name.
198 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 >   the character sets supported can be updated on a per database basis. That is
201 >   it is possible to add a (Firebird) user defined character set to a database.
202  
203 < 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
204 <    DB info lookups"
203 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 >   set supported by Firebird with the API.
205  
206 < 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
206 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 >   in FBOutputBlock.pas and update test suite to include this item.
208  
209 < 19. Add a property Editor for TIBUpdate.RefreshSQL.
209 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210  
211 < 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
212 <    parameters. This stops an exception being raised when the field cannot be
213 <    located in the record buffer.
211 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 >   library or finding it by disk location, the PATH environment variable is now also set to
213 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 >   firebird client library dependencies are loaded.
215  
216 < 21. Property Editors now automatically include System Tables when opened and when the query table
261 <    is a System Table.
216 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217  
218 < 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
264 <    This avoids errors due to a stale SQRB or SRB being used for the next query.
218 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219  
220 < 23. IBServices: Service attach parameters now include "expected_db". This is used to
267 <    add the SPB item isc_spb_expected_db. This names a database using
268 <    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
269 <    database. examples/services re-written to illustrate use of "expected_db".
220 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221  
222 < 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
223 <    This avoids truncated backups when the server returns a timeout (busy) response.
222 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 >    have been given a value (including NULL). Previously, failing to set the
224 >    value of an SQL Parameter could give rise to unpredictable results or
225 >    an SQLDA error.
226  
227 < 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
227 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228  
229 < 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
230 <    databasenames. These are respectively expanded to the local system's temp directory
278 <    (including trailing delimiter) or to a prescribed data directory (including
279 <    trailing delimiter). Under Unix systems the data directory is a hidden directory
280 <    in the user's home directory. The hidden directory name is either the string returned
281 <    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
282 <    Under Windows, the directory is the same as the Data Directory as decribed
283 <    above but instead prefixed by the User's application data path. These may be
284 <    used to improve application portability for Personal Databases.
229 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
231  
232 < 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
233 <    this has not worked for a long time and is not useful either. FieldDefs should be
288 <    managed using the Fields Editor as with any other dataset. To access the fields
289 <    editor for a TIBTable component, double click on the component. The fields editor
290 <    is then displayed.
232 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 >    of const passed to IAttachment.OpenCursor, etc.
234  
292 28. TIBDatabaseInfo: new properties/function
293     * DateDBCreated (returns date/time database created)
294     * TransactionCount (returns no. of active transactions)
295     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
296     * PagesFree (Firebird 3 or later)
297     * PagesUsed (Firebird 3 or later)
298     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
299     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
235  
236 < 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
236 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237  
238 < 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
238 > 1. Change syntax to Mode Delphi
239  
240 < 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
241 <    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
240 > 2. Change all uses of string type to explicit AnsiString in order to ensure
241 >   compatibility between Delphi and FPC.
242  
243 < 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
244 <    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
310 <    firing during backup and restore.
243 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 >   defined for each interface.
245  
246 < 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
313 <    for verbose output using the new property "StatisticsRequested".
314 <    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
246 > 4. Generics syntax variations for Delphi added
247  
248 < 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
248 > 5. PChar replaced with PByte expect where an actual string is being referenced,
249 >   where PAnsiChar is used instead.
250  
251 < 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
319 <    palette. This uses the online validation feature added in Firebird 2.5. The
320 <    services's properties enable inclusion/exclusion of tables and indexes using
321 <    regular expressions. See.
322 <    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
251 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252  
253 < 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
325 <    option on a database.
253 > 7. Testsuite updated for Delphi
254  
255 < 37. TIBCustomService: Assign method implemented to allow copying of service login
328 <    context between service API components. "Detach" method now only detaches
329 <    service when last reference to the service interface detaches. Tidy up of
330 <    code for SetActive and Attach methods including password hiding.
255 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256  
257 < 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
258 <    and used to determine the auth method and protocol used for the connection.
257 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 >   large blobs and the FB3 API.
259  
260 < 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
261 <    a Create Database Statement generated by IBX.
260 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 >   event block.
262  
263 < 40. All IBServices now have an additional published property "PortNo". This may
339 <    be set to a non-standard port number when necessary. If zero then the default
340 <    port number is used.
263 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264  
265 < 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
266 <    and not just the mouse.
265 > 4. Array Handling: fix problem with text arrays with character set none. When the
266 >   DB connection has a default character set (e.g. UTF8), an error is raised by
267 >   Firebird if the space allocated is not enough to allow for transliteration, even
268 >   though it is not required for character set none.
269  
270 < 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
270 > 5. IBUtils: List of reserved words brought up-to-date
271  
272 < 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
348 <    image index and selected image index for each node to be set from a database field.
272 > 6. Add ISQL style performance statistics collection to IStatement
273  
274 < 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
275 <    then database schema includes grants to all users. If not present then the
352 <    only user grants included are those to User PUBLIC.
274 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 >   CREATE DATABASE statement.
276  
277 < 45. TIBTreeView: performance improvement. When expanding include both expanded node
278 <    and child nodes in dataset.
277 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 >   an array dimension is not mistaken for a named parameter prefix.
279  
280 + 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
281 +   when Character set is octets. Avoids loss of non printable characters at start of string.
282  
283 < IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
283 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
284 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 >    to enable stats gathering.
286  
287 < 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
361 <   changes.
287 > 11. API Version information added as constants to IB.pas
288  
289 < 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
364 <   Bug could result in truncated multi-byte character set values.
289 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290  
291 < 3. Changes consequential on moving fbintf character set utility functions from
367 <   IFirebirdAPI to IAttachment.
291 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292  
293 < 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
293 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
294  
295 < 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
372 <   results in autocomplete ignoring prefix text.
295 > 1. Initial Release
296  
374 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
375   entering a new name into the text box.
376
377 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
378   Firebird rather than recomputing it.
379
380 8. Property Editor positioning tidy up: All IBX Property editors should now be
381   screen centre. Previously some were "poDesigned" which may be inappropriate
382   for multi monitor desktops.
383
384 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
385
386 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
387    a transaction and always reset the object.
388
389 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
390
391 13. TIBXScript: Allow for override of database filename in Create Database statements.
392
393 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
394    to a gbak format archive.
395
396 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
397
398 16. IBLocaldb: Drop database if error creating an empty database.
399
400 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
401    unless selected node not in current dataset.
402
403 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
404    to TIBCustomService, and IBlocalDB code tidy up.
405
406 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
407    behaviour due to uninitialised variable.
408
409 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
410    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
411
412 21. IBSQL: When Database changed ensure that all resources are freed.
413
414 22. IBCustomDataset: When database changed ensure that queries an unprepared.
415
416 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
417    * Line Wrap on SQL Token boundaries (on user command)
418    * auto-complete table names in drop down list of table names
419    * Double click on tablename or field name adds to SQL text
420
421 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
422
423 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
424    TVariantArray. Seems to avoid memory corruption in Windows (probably a
425    workaround for a problem in fpc 3.0.4 win64).
426
427 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
428
429 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
430
431 IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
432
433 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
434   include remote system name.
435
436 2. TIBExtract: No longer include comment header and COMMIT statement for empty
437   tables when data included in output.
438
439 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
440   and timing information to be written to stdout. This may be used to locate
441   performance bottlenecks.
442
443 4. SQLParser: only call "OnChanging" event handler when value is different.
444
445 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
446
447 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
448   that BindFields is called when the query is next activated. Avoids FieldName
449   not found error.
450
451 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
452   purpose and allows the programmer to define any action they want for Update, Insert
453   or Delete. This may be complex SQL (similar to a Trigger), application specific
454   filtering of updates, or use of statements such as Grant or Revoke instead of
455   normal DML. See User Manual for more information.
456
457 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
458
459 1. TIBEvents: Fix uninitialised variable that could result in lost events.
460
461 2. TIBExtract: Added support for FB3 "USAGE" privilege.
462
463 3. TIBExtract: data formatted as Charset set "octets" is now output using
464   hexadecimal notation.
465
466 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
467   using a simple XML format.
468
469 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
470   grants to these objects.
471
472 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
473   dependency problems restoring complex databases.
474
475 7. TIBXScript: This component has been restructured to allow for the processing of
476   embedded XML in INSERT statements and to support interactive sources in addition
477   to non-interactive data sources such as files.
478
479 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
480
481 9. TIBXScript: ISQL compatiable Set statements are now supported:
482   SET SQL DIALECT
483   SET TERM
484   SET AUTODDL
485   SET BAIL
486   SET ECHO
487   SET COUNT
488   SET STATS
489   SET NAMES <character set>
490
491 10. IBVersion unit added to hold current IBX Version Number information.
492
493 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
494    and domain definitions.
495
496 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
497    fully supported.
498
499 13. TIBExtract: when a database dump includes data, the generator values are now also set.
500
501 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
502
503 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
504
505 See also doc/IBX4LazarusGuide.pdf for important information on
506 upgrading to IBX2.
507
508 1. Size property of TIBStringField is now the width in characters of the field
509   and not the byte length. This applies only to multi-byte character sets such
510   as UTF8. The original approach aligned with TStringField. However, the TStringField
511   code is not recognised as a bug and hence this change to align the behaviour.
512   The TStringField change is expected in fpc 3.2.0.
513
514 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
515   true (default) then Size property value saved in the lfm is ignored. Size is
516   always set from the dynamic information read from the database. It is unclear
517   why anyone would want to override this and set Size to false.
518
519 3. ibxscript: should now handle correctly a Case..End statement within a procedure
520   block.
521
522 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
523   exist when an attempt is made to connect to it (run time only) then an attempt
524   is made to create the database.
525
526 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
527   has been successfully created as a result of a call to CreateDatabase or when
528   creating a database after it was found not to exist.
529
530 6.  DBControlGrid: a race condition could result in the wrong row image being
531    written to the cache. This has been avoided by a trip round the message
532    loop before rendering the row image.
533
534 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
535    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
536    known to risk corrupt rendering of row images when the control is first
537    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
538    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
539
540 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
541    a TDateEdit control located on an editor panel.
542
543 9.  TIBExtract: brought up-to-date plus many bug fixes.
544
545 10. DBControlGrid: Removed memory leak when updating rows.
546
547 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
548
549 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
550
551 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
552   when target codepage is CP_NONE. This is a workaround for
553   http://bugs.freepascal.org/view.php?id=30622.
554
555 2. DBLog option removed from TIBStatisticalService - not supported by server
556   since Firebird 1.5.
557
558 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
559   similar.
560
561 4. IBCodePage: updated mapping between codepages and character id.
562
563 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
564   Firebird. Character sets with a char width of two are not UTF16.
565
566 6. Strings received from the database are now always transliterated into UTF8
567   regardless of the database character set or connection character set. This
568   is for compatibility with the LCL.
569
570 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
571
572 1. IBBlob: Defer reading of blob until read method called. This avoids having to
573   read in an entire blob just to get the size of the blob. General performance
574   improvement when opening datasets containing blobs.
575
576 2. Clearing a  Blob now sets the corresponding field's modified flag.
577
578 3. IBLookupCombo: When not performing auto-complete, original query sort order
579   is now used.
580
581 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
582   determined.
583
584 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
585
586 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
587   lazarus 1.6.0
588
589 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
590   compilation error.
591
592 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
593
594 1. No character set specified for connection: when a text blob is retrieved, the
595  character set is determined by looking up the native character set using then
596  Firebird API. Otherwise a text mode blob is assumed to have the same character
597  set as the connection.
598
599 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
600   for Login Dialog returing a change to the database path.
601
602 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
603   to be changed from that given in the TIBDatabase/TIBServer component and for the
604   entered value to be saved on a project specific basis (design time only).
605
606 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
607   column fieldname. If they are the same then it is acts as a look up for the KeyValue
608   Otherwise, it sets the column text to the selected ListField Value.
609
610 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
611   column width.
612
613 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
614   and a case insensitive search is requested.
615
616 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
617   or column ListSource.
618
619 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
620   unprepare) when closing and the text has not changed.
621
622 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
623   Less likely to cause a cursor re-use error on Windows.
624
625 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
626   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
627
628 11. TIBTreeView: Guard against nil destination on record changed
629
630 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
631    string type with the code page set to reflect the returned field encoding after
632    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
633    earlier versions.
634
635 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
636    will now result in transliteration to the code page specified for the Firebird driver
637    if the assigned string has a different code page. FPC 3.0.0 onwards only.
638
639 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
640    is ignored and the lc_ctype value, when the database is opened, is set to align with
641    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
642    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
643    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
644    the GETACP is used to determine the Windows code page.
645
646 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
647    name used as the lc_ctype when the database was opened. Only valid while the
648    Database is connected.
649
650 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
651    id that corresponds to the DefaultCharSetName.

653 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
654
655 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
656   path is given and database attach fails due to access permission issues on the
657   temp directory or security database, then the attach is retried with "localhost:"
658   prefixing the databasename. This should avoid problems when the database has to
659   be accessed by a local (e.g. classic) server and libfbembed is used.
660
661 2. Windows: revised search order for Firebird DLL:
662     i.   The Firebird Embedded Server in the application Directory.
663     ii.  If the FIREBIRD environment variable is set then the directory this
664          points to is searched for the FB Client DLL and then then underlying
665          "bin" directory.
666     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
667          is used to locate the Firebird installation directory and the underlying
668          "bin" directory is searched for the FB Client DLL.
669     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
670          are searched for the FB Client DLL.
671     v.   The PATH Environment variable is used to search for the FB Client DLL.
672     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
673
674 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
675   See doc/readme.scriptengine and example applications.
676
677 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
678   simplify the use of the embedded firebird server on both Linux and Windows platforms.
679   See dpc/readme.localdatabase and example applications.
680
681 5. IBDynamicGrid: Reordering on column header click should now also work for
682   dynamic columns.
683
684 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
685   between incrementing/decrementing the lock count and signalling the event.
686
687 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
688
689 1.3.2 was never formally released and only made available as beta copies.
690
691 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
692
693 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
694
695 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
696
697 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
698   i.e. when it is a calculated field
699
700 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
701   This problem was due to a race condition between recalculating row heights and
702   determining which row was selected by the mouse click. The row height calculation
703   is now deferred by an extra trip round the message loop allowing the row to
704   be always calculated on the current grid layout rather than risking it being
705   calculated on the grid layout after the expanded row has been shrunk.
706
707 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
708   Windows.
709
710 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
711   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
712   to be determined at runtime. See doc/readme.charactersets.html.
713
714 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
715   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
716
717 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
718   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
719   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
720
721   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
722   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
723   implies no truncation.
724
725 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
726
727 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
728   (avoids "Not in Edit Mode" error).
729
730 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
731
732 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
733    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
734
735 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
736
737 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
738
739 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
740
741 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
742
743 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
744
745 1.   OnCloseUp Event Handler added to TDBLookupProperties
746
747 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
748     problem with row size when exception is called.
749
750 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
751
752 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
753     in a TCustomComboBox and ignores return key if in a TCustomMemo
754
755 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
756     keyed in i.e. when autocomplete not performed
757
758 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
759     console mode applications with all LCL required functions (builtin dialogs and
760     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
761     not included in your project, IBX should compile and link with a console mode program.
762     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
763     console mode application or the IDE will automatically assume that your
764     application is GUI based. Instead, you should include the ibexpressconsolemode package.
765
766     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
767     to use the built in dialogs and cursor management. IBDialogs is
768     included by default if "ibexpress" is in your project source's "uses" clause.
769     This should be the case for all projects created through the IDE. This is why
770     you do not want to add the ibexpress package to console mode applications. The
771     ibexpressconsolemode package has been created to allow console mode programs
772     to avoid adding LCL dependencies when using IBX, while still having the
773     unit search paths set up correctly.
774
775     Existing users should check to ensure that the "ibexpress" unit is included in
776     each project's source file (*.lpr).
777
778     You may find that in order for the IDE to recognise that ibexpressconsolemode
779     exists, you have to first open the package in the IDE and then close it. This
780     adds it to the most recently accessed packages list. To make it permanently
781     available, add the package name to lazarus' staticpackages.inc file.
782
783         Thanks to Julio Jiménez for suggesting support of console mode.
784
785 7.   SQL Parser can now accept quoted strings that include new lines
786
787 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
788     of text on start of edit. This is particularly useful when tabbing to a
789     column and then inserting text.
790
791 9.   New Examples provided for IB Services and ISQLMonitor.
792
793 10. Fix error when writing to blob streams that recorded only the last buffer
794    write in the blob stream. In most cases, this did not cause a problem as the
795    IB Blob Stream is written in a single write. However, with the TDBImage, write
796    of a graphic type prefix was lost which caused a problem when the image could
797        not be automatically recognised.
798
799 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
800    already open" errors due to random numbers used for the cursor name being identical.
801
802 12. IBTable: corrected error that could result in an "Index out of bounds" error
803    when opening the table and the Primary Key is the last or only column in the
804    table. Thanks to Rick Hoover for the fix.
805
806 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
807    of "UTF-8", and update list of available database character sets. Existing
808    users should check the current lc_ctype setting in their applications.
809
810 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
811
812 1.  Firebird Services: avoid List Index error when opening a service with an
813    empty Params property.
814
815 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
816    Link now set up in Loaded method - avoids occasional failure to apply
817    SQL markup on initial open.
818
819 3.  "Employees" example performance improvements when scrolling.
820
821 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
822    TFrame. Force recaching of selected frame to avoid GTK race (results in a
823    random image cached).
824
825 5.  DBControlGrid: Should now react to changes in panel height at run time.
826
827 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
828    even when further rows exist.
829
830 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
831    always be derived from panel height and setting this property can cause confusion.
832    Note for existing projects: to avoid a missing property error at run time,
833    each form using the DBControlGrid must be opened, updated and saved in the IDE
834    in order to remove the property value from the lfm.
835
836
837 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
838
839 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
840    call Prepare before setting parameter values.
841
842 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
843
844 3.  Code tidyup and more robust handling of dsql information result vector.
845
846 4.  Support for centralised handling of transaction status changes. TIBTransaction
847    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
848    and "AfterExecQuery". The first three are called after the same event is called
849    for an IBCustomDataSet descendent using the Transaction. The fourth is called
850    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
851    enable monitoring of transaction status changes for a given transaction to be
852    handled in a single place. For example, when a change to the dataset occurs
853    an indicator can be set that shows the user that in order to save changes,
854    the transaction should be committed.  Rather than doing this per dataset, this
855    can now be done per transaction.
856
857 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
858    the dataset is scrolled. However, any changes to the current row are, by default,
859    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
860    have a new property "DataSetCloseAction" that adds automatic posting of changes
861    on dataset close. If this property is set to dcDiscardChanges (default) then the
862    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
863    then IBX will attempt to post any unsaved changes before the dataset is closed
864    (and after the BeforeClose event handler is called). The exception is when the
865    dataset is being closed as a result of a transaction rollback. In this case,
866    no action is taken and any unsaved  changes are discarded. This avoids both
867    unnecessary overhead and the risk that a validation error may occur in the Post
868    raising an exception and thereby preventing a rollback.
869
870 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
871    In earlier versions, the Display Width was set to the maximum byte width rather than the character
872    width. Display Widths are now corrected by dividing by the max byte width per character.
873    For UTF8 character sets, the byte width is four and hence the Display Width will be
874    the byte width divided by 4. The byte width of each character set is determined
875    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
876    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
877
878 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
879
880 8.  IBLookupComboEditBox: List should now always be restored to full list when the
881    control loses focus. Default Key press default interval reduced to 200ms.
882
883 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
884    when dataset rows are less than visible rows.
885
886 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
887    does not exist or DataSet is empty. More responsive on dataset open. New event
888    OnRestorePosition. Column sort disabled if no header row.
889
890 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
891    while dataset state is dsInsert. Avoids posting errors.
892
893 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
894    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
895
896 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
897
898 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
899    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
900    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
901    always "posts" the current record regardless or whether or not it may be more appropriate
902    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
903    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
904    as the first action of the "Post" method and allows the handler to convert the Post
905    into a Cancel if that is the appropriate action on moving to a different row. This is
906    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
907    raised here, but it may still be more appropriate to validate a post and signal
908    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
909
910 15. On Unix derived systems, the Firebird library name can now be given as a colon
911    separated list. Each library name on the list is tried in turn, in left to right
912    order with the first found being used as the firebird library. By default, on Linux,
913    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
914    overidden by the FBLIB environment variable or the OnGetLibraryName function.
915
916    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
917    then it will still attempt to access the database via the Firebird Server and will
918    require a username and password. If only the pathname is given, then the username
919    and password should be omitted and the unix file permissions are used to grant
920    access.
921
922 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
923
924 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
925    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
926    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
927    corresponds to a row of the linked DataSource. Any data aware control on the
928    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
929
930 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
931   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
932   takes place during database access. This may be useful when there are performance issues with
933   the change of cursor. Setting the property to false suppresses the change of cursor.
934
935 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
936   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
937   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
938   making all changes permanent immediately rather than when the transaction is explicitly
939   committed.
940
941 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
942   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
943
944 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
945
946 Development version only.
947
948 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
949
950 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
951   This is typically used during an "OnBeforeOpen" event handler to manipulate the
952   "Where" and "Having" clauses to implement user specified filters of arbitrary
953   complexity.
954
955 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
956   three new data aware controls dependent on IBX and which make use of the SQL Parser.
957   These are:
958
959   - TIBLookupComboEditBox
960   - TIBDynamicGrid
961   - TIBTreeview
962
963   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
964   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
965   to revise the available list and restrict it to items that are prefixed by the
966   typed text (either case sensitive or case insensitive). Autoinsert allows a
967   newly typed entry to be added to the list dataset and included in the available
968   list items.
969
970   TIBDynamicGrid is a TDBGrid descendent that provides for:
971   - automatic resizing of selected columns to fill the available row length
972   - automatic positioning and sizing of a "totals" control, typically at the
973     column footer, on a per column basis.
974   - DataSet resorting on header row click, sorting the dataset by the selected column.
975     A second click on the same header cell reversed the sort order.
976   - Support for a "Panel Editor". That is on clicking the indicator column, the row
977     is automatically expanded and a panel superimposed on it. The panel can have any
978     number of child controls, typically data aware controls with the same datasource
979     as the grid allowing for editing of additional fields and more complex editors.
980   - Reselection of the same row following resorting.
981   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
982     Its properties are specified on a per column basis and allows for one or more
983     columns to have their values selected from a list provided by a dataset.
984     Autocomplete and autoinsert are also available. The existing picklist editor
985     is unaffected by the extension.
986
987   TIBTreeView is a data aware TCustomTreeView.
988
989 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
990   zero scale will no longer return an error. An Int64 will be returned instead.
991
992 4. TIBTransaction now has events for Before and After Transaction End and a new function
993   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
994
995 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
996   repeated multiple times.
997
998 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
999   check used to get in the way of using Stored Procedures, and "Update or Insert"
1000   statements.
1001
1002 7. Insert, Modify and Delete property Editors now support Query Generation from
1003   Stored Procedures.
1004
1005 8. Three new examples illustrate the use of the new IB Controls
1006
1007
1008 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1009
1010 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1011   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1012   Gabor Boros for reporting this problem and for testing the improvements).
1013
1014 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1015   See readme.field+param.names in the doc folder.
1016
1017 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1018   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1019
1020 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1021
1022 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1023   actions.
1024
1025 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1026   thanks to Yuriy Kopnin for pointing this out).
1027
1028 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1029
1030 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1031   for both fields and parameter setting.
1032
1033 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1034   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1035
1036 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1037    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1038
1039 11. TIBTable now has a property editor for "MasterFields"
1040
1041 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1042    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.

1044 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination

1054 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1055   it is null. This allows for alternative user defined setting of the generator
1056
1057   Many thanks to Julio Jiménez for this fix
1058
1059 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1060   and suggests that the user may have forgotten to install it.

1066

1078
1079 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1080   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1081
1082 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1083   package is changed to do this (which it should do).
1084

1086
1087 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1088
1089 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1090
1091 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1092
1093 4. Property editors should now correctly resize.
1094
1095 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1096   (restored original functionality)
1097
1098 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1099   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
