Merge of r5027, r5028, r5029: fastcgi_keep_conn fixes. *) FastCGI: fixed wrong connection close with fastcgi_keep_conn. With fastcgi_keep_conn it was possible that connection was closed after FCGI_STDERR record with zero padding and without any further data read yet. This happended as f->state was set to ngx_http_fastcgi_st_padding and then "break" happened, resulting in p->length being set to f->padding, i.e. 0 (which in turn resulted in connection close). Fix is to make sure we continue the loop after f->state is set. *) FastCGI: unconditional state transitions. Checks for f->padding before state transitions make code hard to follow, remove them and make sure we always do another loop iteration after f->state is set to ngx_http_fastcgi_st_padding. *) FastCGI: proper handling of split fastcgi end request. If fastcgi end request record was split between several network packets, with fastcgi_keep_conn it was possible that connection was saved in incorrect state (e.g. with padding bytes not yet read).
