IXR - The Incutio XML-RPC Library - (c) Incutio Ltd 2002
Version 1.61 - Simon Willison, 11th July 2003 (htmlentities -> htmlspecialchars)
Site: http://scripts.incutio.com/xmlrpc/
Manual: http://scripts.incutio.com/xmlrpc/manual.php
Errors: http://xmlrpc-epi.sourceforge.net/specs/rfc.fault_codes.php
Made available under the Artistic License: http://www.opensource.org/licenses/artistic-license.php
Modified to support protocol 'GbxRemote 2' ('GbxRemote 1')
This version is for BigEndian machines. For LittleEndian (e.g. Intel PC)
machines use the original GbxRemote.inc.php instead.
Release 2007-09-22 - Slig:
Modified to support >256KB received data (and now >2MB data produce a specific error message)
Modified readCB() to wait the initial timeout only before first read packet
Modified readCB() to return true if there is data to get with getCBResponses()
Modified to support amd64 (for $recvhandle)
Modified IXR_ClientMulticall_Gbx::addCall() to fit Aseco 0.6.1
Added IXR_Client_Gbx::bytes_sent & bytes_received counters
Fix for a changed feature since php5.1.1 about reference parameter assignment (was used in stream_select)
Workaround for stream_select return value bug with amd64
Release 2008-01-20 - Slig / Xymph / Assembler Maniac:
Workaround for fread delay bug in some cases
Added IXR_Client_Gbx::resetError() method (by Xymph)
Some comments and strings code cleanup (by Xymph)
Fix stream_set_timeout($this->socket,...) (thx to CavalierDeVache)
Added a default timeout value to IXR_Client_Gbx::readCB($timeout)
Changed calls with timeout on a stream to use microseconds instead of seconds (by AM)
Removed IXR_Client_Gbx::bytes_sent & bytes_received counters - not used (by AM)
Release 2008-02-05 - Slig:
Changed some socket read/write timeouts back to seconds to avoid 'transport error'
Changed max data received from 2MB to 4MB
Release 2008-05-20 - Xymph:
Prevented unpack() warnings in IXR_Client_Gbx::query() when the connection dies
Changed IXR_Client_Gbx::resetError() to assign 'false' for correct isError()
Tweaked some 'transport error' messages
Release 2009-04-08 - Gou1:
Added method IXR_Client_Gbx::queryIgnoreResult()
Added methods IXR_Client_Gbx::sendRequest() & IXR_Client_Gbx::getResult()
IXR_Client_Gbx::queryIgnoreResult checks if the request is larger than 512KB to avoid errors
If larger than 512KB and method is system.multicall, try to divide the request into
two separate requests with two separate IXR_Client_Gbx::queryIgnoreResult() calls
Release 2009-06-03 - Xymph:
Suppress possible repetitive CRT warning at stream_select
Release 2011-04-09 - Xymph / La beuze:
Added optional timeout mechanism to IXR_Client_Gbx::InitWithIp()
Release 2011-05-22 - Xymph:
Added non-error (true) return status to IXR_Client_Gbx::queryIgnoreResult()
Updated status codes and messages for transport/endian errors
Prevented possible PHP warning in IXR_Client_Gbx::getErrorCode() and getErrorMessage()
Release 2011-12-04 - Xymph:
Prevented possible PHP warning in IXR_Value::calculateType
Release 2013-02-18 - Xymph:
Removed unnecessary breaks after returns in IXR_Value::getXml() switch
