Subject [jira] Commented: (AXISCPP-847) Wrong definition of INVALID_SOCKET for non MS Windows platforms.
Date Thu, 06 Oct 2005 00:39:51 GMT
    [ http://issues.apache.org/jira/browse/AXISCPP-847?page=comments#action_12331451 ] 

nadir amra commented on AXISCPP-847:
------------------------------------

I will look into this further.  An invalid socket should be -1.  I think (please someone comment
if not) that this is true for windows sockets so that chaning invalid socket constant to -1
should be ok. 

The reason people do not have trouble with this on other platforms is because descriptors
0, 1, and 2 are reserved for stdin, stdout and stderr.  On OS/400, if you kick off your program
from within qshell, this will also be true.  I assume on OS/400 you are kicking off the client
program from CL command line.  

This will be fixed.

>      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.
