+FBINTF Change Log  version          (1.4-2 Build 14156) Sat, 23 Dec 2023 15:05:47 +0000
-+
-+
+. IBUtils.FormatTimeZoneOffset A zero offset now includes a preceding '+' sign.
-+
-+
+. TFBStatement.DoJournaling now exits immediately if journaling is not active. The
-+
+   motivation for this is to avoid calling the Firebird API function 'getInfo'
-+
+   unnecesarily. This function can return an error if an incompatible parameter type was
-+
+   applied to the statement and hence can confuse resolving the bug. Note: a
-+
+   specific case is in (e.g.) OpenCursorAtStart method when the array of const includes a
-+
+   TDateTime. In this case, the param is set to a floating point type rather than
-+
+   a Firebird datetime (array of const loses the distinction).
-+
-+
+. TFBAttachment.SetParameters. if an attempt is made to set a parameter with a float
-+
+   value, the metadata type is checked to see if the parameter is a Date/Time type. If so then
-+
+   the value is assumed to be a TDateTime and the parameter is set using the AsDateTime
-+
+   property. Otherwise, the value is assumed to be a floating point type and the AsDouble
-+
+   property is used to set the property. This avoids the specific example given above.
-+
-+
+FBINTF Change Log  version          (1.4-1 Build 14103) Mon, 27 Nov 2023 14:26:35 +0000
-+
-+
+. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
-+
+   checks for range checking.
-+
-+
+. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
-+
+   any additional error information is decoded.
-+
-+
+. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
-+
+   charsetid is now preserved and size is set to default blob size. Now aligns with
-+
+   FB3 and later.
-+
-+
+. DDL and DML string literals are now explicitly set to the connection character
-+
+   set rather than the default character set provided by the compiler.
-+
-+
+. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
-+
+   now makes use of the RTL fpwidestring unit for support of international character
-+
+   sets.
-+
-+
+. Database exception handling (see section 9.3 in user guide).
-+
+    * For FB3 and later API: Connection Character set now applied to message returned
-+
+      by fb_interpret and message then transliterated if necessary to the system character set.
-+
+    * For Legacy API: The message character set is guessed as UTF8 unless invalid
-+
+      UTF8 characters found when connection character set is assumed. Message then
-+
+      transliterated if necessary to system character set.
-+
+      Note: this difference of behaviour is because legacy API presents exception messages
-+
+      "as is", while FB3 server attempts to transliterate to connection character set.
-+
-+
+FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
-+
-+
+. Support package fbudr added for support of User Defined Routines (UDRs), and package
-+
+   fbudrtestbed for client side debugging of UDR libraries.
-+
-+
+. Package layout changed with introduction of udr support. IB*.pas files moved from
-+
+    root directory to "client". IBHeader moved to "Client".
-+
-+
+. Delphi packages: all packages now compile .dcp and .bpi files to either
-+
+   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
-+
+   fbintf.dcp and fbintf.bpi files from other locations.
-+
-+
+. Client side journaling support added. Interface changes
-+
+   IAttachment
-+
+    function JournalingActive: boolean;
-+
+    function GetJournalOptions: TJournalOptions;
-+
+    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
-+
+    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
-+
+    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
-+
+    procedure StopJournaling(RetainJournal: boolean);
-+
-+
+. Transactions may now be given a local transaction name:
-+
+   IFirebirdAPI
-+
+     function StartTransaction(Attachments: array of IAttachment;
-+
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
-+
+             aName: AnsiString=''): ITransaction; overload;
-+
+     function StartTransaction(Attachments: array of IAttachment;
-+
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
-+
+             aName: AnsiString=''): ITransaction; overload;
-+
-+
+   IAttachment
-+
+    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+    function StartTransaction(TPB: array of byte;
-+
+                              DefaultCompletion: TTransactionCompletion=taCommit;
-+
+                              aName: AnsiString=''): ITransaction; overload;
-+
+    function StartTransaction(TPB: ITPB;
-+
+                              DefaultCompletion: TTransactionCompletion=taCommit;
-+
+                              aName: AnsiString=''): ITransaction; overload;
-+
-+
+  ITransaction
-+
+    function GetTransactionName: AnsiString;
-+
+    procedure SetTransactionName(aValue: AnsiString);
-+
-+
+. Additional Transaction information
-+
+     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
-+
-+
+   ITransaction
-+
+     function GetDefaultCompletion: TTransactionCompletion;
-+
+     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
-+
-+
+. New IAttachment helper functions
-+
+     function HasTable(aTableName: AnsiString): boolean;
-+
+     function HasFunction(aFunctionName: AnsiString): boolean;
-+
+     function HasProcedure(aProcName: AnsiString): boolean;
-+
+     function GetAttachmentID: integer;
-+
+     function GetCharSetID: integer;
-+
-+
+. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
-+
+   will be allocated for batch operations.
-+
-+
+. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
-+
+    function GetStatement: IStatement;
-+
+    function GetTransaction: ITransaction;
-+
+    function GetAttachment: IAttachment;
-+
-+
+. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
-+
+    interfaces.
-+
-+
+. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
-+
+    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
-+
+    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
-+
+    of numerics without loss of precision.
-+
-+
+. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
-+
-+
+. ISQLParams new method "Clear"
-+
-+
+. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
-+
+    request rather than on attachment connect.
-+
-+
+. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
-+
+    fact that SQLCodes are soon to be deprecated. In the future, the other options
-+
+    will be silently ignored if SQLCode support is not present in the Firebird
-+
+    Client library.
-+
-+
+. ITransaction changes Rollback and Commit from procedures to functions:
-+
+      function Commit(Force: boolean=false): TTrCompletionState;
-+
+      function Rollback(Force: boolean=false): TTrCompletionState;
-+
-+
+    Specifically, this is to allow the functions to report back a failed commit or
-+
+    rollback when Force = true. In the case, the transaction handle has been
-+
+    released, while the transaction remains in limbo.
-+
-+
+. IAttachment ExecImmediate.
-+
+    When the transaction parameters are provided as an array of const and the
-+
+    statement fails, the transaction is rolledback (forced) before the exception
-+
+    is raised.
-+
-+
+. In Firebird 3 and later API: the status vector is now a thread var, as was
-+
+    already the case with the legacy API. Avoids problems when calling underlying
-+
+    Firebird API in multiple threads.
-+
-+
+. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
-+
+    reasons.
-+
-+
+. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
-+
-+
+. TSQLXMLReader: handle 'blob' as a reserved word
-+
-+
+. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
-+
-+
-+
+FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
-+
-+
+. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
-+
-+
+. Remove constraint in IAttachment.HasScollableCursors that returned false when
-+
+   using remote protocol. Scrollable cursors with remote database expected to
-+
+   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
-+
+   a not supported error.
-+
-+
+. IStatement: new function;
-+
+    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
-+
+    TStatementFlags = set of TStatementFlag;
-+
+    function GetFlags: TStatementFlags;
-+
-+
+. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
-+
+   compatibility.
-+
+   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
-+
+   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
-+
+   to be used with Update...Retruning statements that return a singleton row,
-+
+   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
-+
+   it will open the cursor and return the first row only.
-+
-+
+. ITransaction: new functions:
-+
+    function GetIsReadOnly: boolean;
-+
+    function GetTransactionID: integer;
-+
+    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
-+
+    function GetTrInformation(Request: byte): ITrInformation; overload;
-+
-+
+   The latter two return the Transaction Information block. The first two extract
-+
+   information the Transaction Information block
-+
-+
+. New function TSQLTokeniser.ReadCharacters
-+
+   Used internally.
-+
-+
+. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
-+
+   parameter placeholders instead of named parameters.
-+
-+
+. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
-+
+   transaction handle is now ignored if Rollback/Commit is called with Force=true
-+
-+
+. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
-+
+   used to get an IBError Message instead of isc_interprete.
-+
-+
+. Internal tidyup. Native code now used for decoding integers and the events
-+
+    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
-+
+    isc_event_block and isc_event_counts.
-+
-+
+. New IAttachment function
-+
+     function GetAttachmentID: integer;
-+
-+
+. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
-+
+    subclasses to enable UDR support.
-+
-+
+FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
-+
-+
+. TFBClientAPI.GetProcAddr. Add check for nil reference.
-+
-+
+. IStatement: new methods:
-+
+    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
-+
+    function GetStaleReferenceChecks: boolean;
-+
-+
+   In previous versions, stale reference checks were always enabled. This allows the
-+
+   user to disable them on a per statement basis. Note this can risk out-of-date
-+
+   statement BLR. See User Guide.
-+
-+
+. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
-+
+   stored procedure and hence avoids replacing named parameters within a containing
-+
+   BEGIN..END block.
-+
-+
+. ISQLParam: using a string value to set an integer field with a scale factor of
-+
+   zero is now treated as a special case to avoid the risk of floating point
-+
+   rounding errors affecting pure integers.
-+
-+
+. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
-+
-+
+. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
-+
+   SQL Parameter metadata (methods moved from ISQLParam).
-+
-+
+. ISQLParam: new method
-+
+     function getColMetadata: IParamMetaData;
-+
+   This instance of IParamMetaData returns the original column metadata which is unmutable.
-+
+   Note: ISQLParam metadata can change after a parameter value has been set e.g when
-+
+   setting a VARCHAR column to an integer value.
-+
-+
+. IStatement: can now set cursor name when opening a cursor. New overloaded method:
-+
+    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
-+
+   also IAttachment:
-+
+    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
-+
+    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
-+
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
-+
+                       aSQLDialect: integer; GenerateParamNames: boolean=false;
-+
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
-+
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
-+
+                       GenerateParamNames: boolean=false;
-+
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
-+
-+
+. Support for scrollable cursors added. New/updated methods:
-+
+   IAttachment:
-+
+    function HasScollableCursors: boolean;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
-+
+                             Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
-+
+                             Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+   IStatement:
-+
+     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
-+
+   IResultSet:
-+
+    function FetchPrior: boolean; {fetch previous record}
-+
+    function FetchFirst:boolean; {fetch first record}
-+
+    function FetchLast: boolean; {fetch last record}
-+
+    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
-+
+    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
-+
+    function IsBof: boolean;
-+
-+
+. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
-+
-+
+. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
-+
+    may be noticeable when a line separator occurs inside quoted text. The quoted text
-+
+    output by the tokeniser will now use the platform specific lineEnding regardless
-+
+    of whether the input uses the CRLF or LF as a line separator.
-+
-+
+. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
-+
-+
-+
+FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
-+
-+
+. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
-+
-+
+. Support for inline blob encoding. Blob values pass using the "SetAsString" method
-+
+   will now be encoded inline (i.e. as part of the parameter buffer) if they are
-+
+   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
-+
+   separate server interaction. This is intended as a performance optimisation.
-+
-+
+   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
-+
+   IAttachment interface functions:
-+
-+
+    function GetInlineBlobLimit: integer;
-+
+    procedure SetInlineBlobLimit(limit: integer);
-+
-+
+. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
-+
+   user as the functionality is embedded in the implementation of the IStatement
-+
+   interface. Three new functions are defined:
-+
-+
+    procedure AddToBatch;
-+
+    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
-+
+    procedure CancelBatch;
-+
+    function GetBatchCompletion: IBatchCompletion;
-+
+    function GetBatchRowLimit: integer;
-+
+    procedure SetBatchRowLimit(aLimit: integer);
-+
-+
+   Also
-+
-+
+    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
-+
+    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
-+
-+
+   For more information see the User Guide.
-+
-+
+. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
-+
+   provided with the EIBInterBaseError now include all three parts.
-+
-+
+. Firebird.pas and include files updated to Firebird 4.0.0
-+
-+
+. New IStatement method: function GetSQLStatementTypeName: AnsiString;
-+
+   Returns SQL Statement type as a text string;
-+
-+
+. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
-+
+   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
-+
-+
+FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
-+
-+
+. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
-+
+   typo in FB30Statement.pas that caused an unknown parameter error.
-+
-+
+FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
-+
-+
+. Imported (Firebird) constants updated for Firebird 4.
-+
-+
+. Firebird.pas from Firebird 4 integrated into source code tree.
-+
-+
+. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
-+
-+
+. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
-+
-+
+. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
-+
+   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
-+
+   interface provides a single method "function GetIMasterIntf: IMaster". This provides
-+
+   type safe access to the Firebird IMaster interface and avoids the need to turn
-+
+   off object checks when coercing "function GetIMaster: TObject" to IMaster.
-+
-+
+. New IFirebirdAPI Calls:
-+
+    function HasLocalTZDB: boolean;
-+
+    function HasTimeZoneSupport: boolean;
-+
+    function HasExtendedTZSupport: boolean;
-+
+    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
-+
+    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
-+
-+
+. New IAttachment Calls:
-+
+    function HasDecFloatSupport: boolean;
-+
+    function GetTimeZoneServices: ITimeZoneServices;
-+
+    function HasTimeZoneSupport: boolean;
-+
-+
+. New Interface ITimeZoneServices.
-+
-+
+. New ISQLData API Calls:
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

-+
+    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
-+
+    function GetAsUTCDateTime: TDateTime;
-+
+    function GetAsBCD: tBCD;
-+
-+
+. New ISQLParam API Calls
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

-+
+    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
-+
+    procedure SetAsBcd(aValue: tBCD);
-+
-+
+. New IArray API Calls
-+
+    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

+      function getParamTypeName: AnsiString;
-+
-+
+. fb_shutdown now called before unloading Firebird library. This can avoid a
-+
+     SIGEVENT error when a programme using the embeded server is unloaded.
-+
-+
+FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
-+
-+
+. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
-+
+   with a Firebrid 3 client library.
-+
-+
+. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
-+
+    If a client library path is not explicitly provided and the FIREBIRD environment
-+
+    variable is set then the directory given by this variable and any 'lib' subdirectory
-+
+    are searched for the Firebird client library. Only if none is found, is the default
-+
+    client library used.
-+
-+
+.  IUtil.FormatStatus now used to format error messages when using new API
-+
-+
+.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
-+
-+
+.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
-+
+    returned using GetAsString and the string codepage is UTF8, the string is truncated so
-+
+    that the byte length corresponds to the number of characters specified for the column.
-+
+    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
-+
+    correct behaviour but may affect some implementations that relied upon automatic
-+
+    trimming of trailing white space.
-+
-+
+.  New IFirebirdAPI Calls:
-+
+      function GetClientMajor: integer;
-+
+      function GetClientMinor: integer;
-+
-+
+.  IColumnMetaData and IArrayMetaData: new method
-+

+FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
-+
-+
+. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
-+
+   case sensitive
-+
-+
+. Single line SQL comments starting with '--' are now recognised by SQL Parser.
-+
-+
+. New API Calls:
-+
+        IColumnMetaData.GetStatement

+        IColumnMetaData.GetTransaction
-+
+        ISQLData.GetStrDataLength

+FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
-+
-+
+. Fix a problem with the SQL parameter parser that failed to recognise parameters
-+
+   where the second character of the parameter name is a numeric.
-+
-+
+. New method for IAttachment: procedure getFBVersion(version: TStrings);
-+
+   This returns the isc_version connection information as one or more lines.
-+
+   This is the same information as returned by isql with the -z option.
-+
-+
+. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
-+
+   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
-+
+   compiler option then the Firebird 3 API is no longer compiled in.
-+
-+
+. IColumnMetaData: new method.
-+
-+
+   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
-+
+                        dfDateTime,   {SQL DATETIME}
-+
+                        dfTime);
-+
-+
+   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
-+
-+
+   This returns the max. number of characters returned by the "AsString" method
-+
+   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
-+
-+
+. Additional argument for IAttachment.PrepareWithNamedParameters -
-+
+     CaseSensitiveParams: boolean = false
-+
-+
+   If this argument is set to true then SQL parameter names are assumed to be case
-+
+   sensitive and must be referenced (using ISQLParams.ByName) using the case
-+
+   sensitive name.
-+
-+
+. Bug fix: when setting a query parameter, it is now possible, when the parameter
-+
+   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
-+
+   .AsCurrency) and then subsequently to update the value to a non-numeric string
-+
+   using .AsString.

+FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
-+
-+
+. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
-+
-+
+. Restrict IsMultiThread check to Unix only for compatibility with
-+
+   https://bugs.freepascal.org/view.php?id=30535
-+
-+
+. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
-+
+   named parameters and is intended to avoid problems with (e.g.) Execute Block
-+
+   and processing internal parameters as statement parameters.
-+
-+
+. New interface IFirebirdLibrary provides access to the underlying firebird DLL
-+
+   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
-+
-+
+. New function added to IB.pas
-+
-+
+   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
-+
-+
+   This allows a Firebird Library to be loaded from an explicit path. use the
-+
+   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
-+
+   the library. It is possible to load Firebird libraries from different locations
-+
+   simultaneously, each with a distinct IFirebirdAPI.

-+
+FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
-+
-+
+. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
-+
+   program compiled with -CR command line switch.
-+
-+
+. IServiceManager additions (informational):
-+
+    function getProtocol: TProtocol;
-+
+    function getPortNo: AnsiString;
-+
-+
+. IServiceManager improved error handling. Interfaces changed:
-+
+    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
-+
+    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;

-+
-+
+. IAttachment addition (informational)
-+
+    function GetSecurityDatabase: AnsiString;
-+
-+
+. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
-+
+   thus now returns accumulated stats for a select statement from opening a cursor
-+
+   up to the last fetch.
-+
-+
+. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
-+
+   the problem.
-+
-+
+. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
-+
+   replaces deprecated "comp" type.
-+
-+
+. Testsuite Test10 updated to include thread synchronisation for event reporting.
-+
-+
+. URL Connection Strings: inet4 and inet6 now recognised.
-+
-+
+. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
-+
-+
+. IAttachment.CharSetName2CharSetID is now performed case insensitive.

+FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
-+
-+
+. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
-+
-+
+. IAttachment: add two new methods
-+
+     function HasDefaultCharSet: boolean;
-+
+     function GetDefaultCharSetID: integer;
-+
-+
+   These return, respectively, true if a connection default character set was
-+
+   specified and the character set id of the connection default character set.
-+
+   The DefaultCharSetID is cached when the connection is opened and hence does not
-+
+   require a database lookup.
-+
-+
+. Avoid exception when a text blob is a stored procedure parameter.
-+
-+
+. Update test suite to include a test for a stored proc returning a text blob.
-+
-+
+. IAttachment: add
-+
+      function GetRemoteProtocol: AnsiString;
-+
+      function GetODSMajorVersion: integer;
-+
+      function GetODSMinorVersion: integer;
-+
+      function GetAuthenticationMethod: AnsiString;
-+
-+
+   These results are cached when the connection is opened and hence do not
-+
+   require a database lookup.
-+
-+
+. IAttachment: add "function GetConnectString: AnsiString;" This returns the
-+
+   connect string used to create/connect to the database.
-+
-+
+. IAttachment: Create Database using SQL statement. The username and password
-+
+   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
-+
+   It is now possible to use IAttachment disconnect/connect to reconnect to
-+
+   a database for which the initial connection was established by a create
-+
+   database sql statement. Available in FPC only.
-+
-+
+. Update Test 1 to test 5, 6 and 7 above.
-+
-+
+. IBUtils code tidy up.
-+
-+
+. Parameter Block interfaces "find" method. As documented, this should have
-+
+   returned a nil interface when the item could not be found. Instead, an empty
-+
+   interface item was returned. "Find" now works as documented and will return
-+
+   a nil interface if the item cannot be found.
-+
-+
+. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
-+
-+
+. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
-+
+    requests with additional parameters. This is to enable support for fb_info_page_contents
-+
+    (return of page contents). Response to fb_info_page_contents returned as
-+
+    a string with code page CP_NONE.
-+
-+
+. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
-+
+    test suite updated.
-+
-+
+. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
-+
+    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
-+
-+
+. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
-+
+    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
-+
+    default connection port to be specified.

-+
+FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
-+
-+
+. Fix issues with setting SQL Param values using SetAsString with Numeric types.
-+
+   Scale is no longer ignored.
-+
-+
+. Fix issues with setting SQL Param values using SetAsString with Date values
-+
+   not in locale format but which are recognised by Firebird. Date values that
-+
+   cannot be converted to a string using Pascal library are now passed through
-+
+   to Firebird as Text Strings.
-+
-+
+. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
-+
+   UTF8 and not UNICODE_FSS.
-+
-+
+. Charset ID problem. When using Firebird 3, with no default database character set
-+
+   and a column has a non-default collation specified, an incorrect character set
-+
+   id was being reported that could result in a 'division by zero' error when
-+
+   used by IBX. This has now been fixed.
-+
-+
+. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
-+
+   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
-+
+   the character sets supported can be updated on a per database basis. That is
-+
+   it is possible to add a (Firebird) user defined character set to a database.
-+
-+
+. Add RegisterCharSet to IAttachment. This is used to register a user defined character
-+
+   set supported by Firebird with the API.
-+
-+
+. Add missing isc_info_db_read_only to list of decoded Database Information items
-+
+   in FBOutputBlock.pas and update test suite to include this item.
-+
-+
+. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
-+
-+
+. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
-+
+   library or finding it by disk location, the PATH environment variable is now also set to
-+
+   include the FIREBIRD directory. This is to ensure that the correct dlls in the
-+
+   firebird client library dependencies are loaded.
-+
-+
+. Testsuite: Ensure consistent UTF-8 output on Windows console.
-+
-+
+. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
-+
-+
+. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
-+
-+
+. FB30Statement: A check has been added to ensure that all SQL Parameters
-+
+    have been given a value (including NULL). Previously, failing to set the
-+
+    value of an SQL Parameter could give rise to unpredictable results or
-+
+    an SQLDA error.
-+
-+
+. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
-+
-+
+. FBAttachment: Avoid string reference count error when processing an Ansistring
-+
+    parameter in an array of const passed to IAttachment.OpenCursor, etc.
-+
-+
+. FBAttachment: Allow for WideString and UnicodeString parameters in an array
-+
+    of const passed to IAttachment.OpenCursor, etc.

-+
-+
+. Change syntax to Mode Delphi
-+
-+
+. Change all uses of string type to explicit AnsiString in order to ensure
-+
+   compatibility between Delphi and FPC.
-+
-+
+. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
-+
+   defined for each interface.
-+
-+
+. Generics syntax variations for Delphi added
-+
-+
+. PChar replaced with PByte expect where an actual string is being referenced,
-+
+   where PAnsiChar is used instead.
-+
-+
+. Review of type definitions in IBExternals to ensure Delphi compatibility
-+
-+
+. Testsuite updated for Delphi

-+
+FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
-+
-+
+. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
-+
+   large blobs and the FB3 API.
-+
-+
+. Update Event Handling algorithm to avoid looping due to recreation of the
-+
+   event block.
-+
-+
+. Avoid invalid XSQLDA error when the only parameter is updated to null
-+
-+
+. Array Handling: fix problem with text arrays with character set none. When the
-+
+   DB connection has a default character set (e.g. UTF8), an error is raised by
-+
+   Firebird if the space allocated is not enough to allow for transliteration, even
-+
+   though it is not required for character set none.
-+
-+
+. IBUtils: List of reserved words brought up-to-date
-+
-+
+. Add ISQL style performance statistics collection to IStatement
-+
-+
+. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
-+
+   CREATE DATABASE statement.
-+
-+
+. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
-+
+   an array dimension is not mistaken for a named parameter prefix.
-+
-+
+. Trim function no longer applied to result of GetAsString for SQL_TEXT
-+
+   when Character set is octets. Avoids loss of non printable characters at start of string.
-+
-+
+. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
-+
+    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
-+
+    to enable stats gathering.
-+
-+
+. API Version information added as constants to IB.pas
-+
-+
+. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
-+
-+
+. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
