Re: [Perlgssapi-developer] Warning cropping up...

[Merijn B. <me...@il...>]

I changed the code in Context.xs to look like this: 

void
DESTROY(context)
        GSSAPI::Context_opt     context
    PREINIT:
        OM_uint32               minor;
        OM_uint32               major;
    CODE:
        if (context != NULL) {

            major = gss_delete_sec_context(&minor, &context, GSS_C_NO_BUFFER);
            if ( major == GSS_S_COMPLETE) {
               warn("gss_delete_sec_context() complete in module Context.xs");
            }
            if ( major == GSS_S_NO_CONTEXT) {
               warn("failed gss_delete_sec_context() with invalid context in  module Context.xs");
            }
            if ( major == GSS_S_FAILURE) {
               warn("failed gss_delete_sec_context() with unspecified error in module Context.xs");
            }

        }

so I could figure out what was going on. 

turns out that my code looks like this in broad overview: 

  while (1) {
    my $sec_context ;
  
    ...
  
    $sec_context->DESTROY;
  }

which means the DESTROY is called twice. Once by me explicitly and once
on destruction of the variable. 

My server output now looks like this:

SERVER::waiting for request ...
SERVER::accepted connection from client ...
SERVER::received token (length is 459):
SERVER::authenticated client name is me...@is...
SERVER::Have mutual token to send ...
SERVER::GSS token size: 114
SERVER::sent token (length is 114)
gss_delete_sec_context() complete in module Context.xs at gss-server.pl line 159, <GEN3> line 1.
failed gss_delete_sec_context() with invalid context in  module Context.xs at gss-server.pl line 159.

So my bad. 

But we might want to make this more forgiving, by only warning on
GSS_S_FAILURE, not on GSS_S_NO_CONTEXT. ;-)
