Re: HTTP doesn't work after upgrading from 2.0.55 to 2.2.15

Hi William,

I reckon it should be mod_cgi, the CGI library I use is called "GNU CGI Library in C, v0.9.5" which has been maintained for many years. 

The function below is the way the CGI init and open the stream.

gcgiReturnType

initCgi( )

{

    /* Dup stdout to gcgiOut */

    gcgifd = dup(fileno(stdout));

    gcgiOut = fdopen(gcgifd, "w");

.

.

}

Then, free the resource but I didn't see it close the file descriptor. It duplicate the standard output, is that the reason that don't have to close it? I've tried to close the stdout, stderr, gcgiOut, stdin, but that didn't work.

void

freeCgi( )

{

    freeCgiQuery();

    if (envVariablesFile != NULL) XFREE(envVariablesFile);

    if (cgiQueryFile != NULL) XFREE(cgiQueryFile);

}

Thanks,

Best regards,

honercek

If the CGI closes the stream (EOF) then everything should still work out
alright.  How do you handle the CGI within httpd?  mod_cgi, mod_cgid, or
with mod_fcgid?  Or with some other module?
