Subject [jira] Created: (AXISCPP-847) Wrong definition of INVALID_SOCKET for non MS Windows platforms.

Wrong definition of INVALID_SOCKET for non MS Windows platforms.
----------------------------------------------------------------

         Key: AXISCPP-847
         URL: http://issues.apache.org/jira/browse/AXISCPP-847
     Project: Axis-C++
        Type: Bug
  Components: Transport (axis3)  
    Versions: 1.5 Final    
 Environment: i5/OS (OS/400 iSeries) and *nix (Linux and others)
    Reporter: Ernst Mikkelsen
    Priority: Critical


In HTTPChannel.hpp and HTTPSSLChannel.hpp, INVALID_SOCKET is defined as 0 (zero). This causes
a client using Axis C++ to fail consequently with a HTTPTransportException on the first connection
attempt on the i5/OS, because 0 (zero) in fact is a valid socket descriptor on the i5/OS platform
(as well as it is on other platforms such as Linux). This also means that real errors are
not caught because -1 from the API is compared with to a 0 (zero).

To my knowledge, all platforms defines socket() to return either -1 or ~0 depending on whether
socket() is implemented with a signed or unsigned return value.

My suggestion would be to change the following two files:
  HTTPChannel.hpp    line 56 in Axis C++ 1.5 Final
  HTTPSSLChannel.hpp line 58 in Axis C++ 1.5 Final

  from: const unsigned int INVALID_SOCKET =  0;
  to:   const unsigned int INVALID_SOCKET = ~0;  // for unsigned socket() implementations
  or:   const          int INVALID_SOCKET = -1;  // for signed socket() implementations

As a workaround for this issue, I've tried to allocate a dummy socket in my client program
before calling any of the Axis C++ methods, causing Axis C++ to succeed on the first connection
attempt.
