It's not totally flawless but not that bad either.
f = open(url, O_RDONLY);
if (f >= 0) {

You mix up statements and declarations. Busybox build system issues warnings.

What will happen if f_stat.st_size > INT_MAX (2 gb) ?
+#else
int count;
char *buf = iobuf;
-
- sendHeaders(HTTP_OK);
- /* TODO: sendfile() */
while ((count = full_read(f, buf, MAX_MEMORY_BUFF)) > 0) {
- int fd = accepted_socket;
- if (fd == 0) fd++; /* write to fd# 1 in inetd mode */
if (full_write(fd, buf, count) != count)
break;
}
+#endif
close(f);
I applied it with some changes, please test current svn.
Thanks!
