#145 send(res_buf) error

[Anonymous]

I have compiled from CVS HEAD on OpenBSD 5.1 release.
I get send(2) error depending on what content I have in my media database. With just a few files I don't get any error.

I get the following type of error in the log:
[2012/06/26 11:00:59] upnphttp.c:1284: error: send(res_buf): 23360 bytes sent (out of 31739)

It seems that the case where not all bytes are sent over socket is unhandled (upnphttp.c) looking at TODO ...

void
SendResp_upnphttp(struct upnphttp * h)
{
int n;
DPRINTF(E_DEBUG, L_HTTP, "HTTP RESPONSE: %.*s\n", h->res_buflen, h->res_buf);
n = send(h->socket, h->res_buf, h->res_buflen, 0);
if(n<0)
{
DPRINTF(E_ERROR, L_HTTP, "send(res_buf): %s\n", strerror(errno));
}
else if(n < h->res_buflen)
{
/* TODO : handle correctly this case */
DPRINTF(E_ERROR, L_HTTP, "send(res_buf): %d bytes sent (out of %d)\n",
n, h->res_buflen);
}
}

When this error occur I don't get any data to the media renderer (Windows Media Player in this case):
