Every other failure condition in that function was alreadying doing this,
and I saw a case with a lot of "mkstemp...No space left on device" messages
started becoming "mkstemp...Too many open files" messages because of this
bug. Not that it makes a whole lot of difference, since nothing gets copied
because the disk was out of space.
rprintf(FERROR,"mkstemp %s failed: %s\n",fnametmp,strerror(errno));
receive_data(f_in,buf,-1,NULL,file->length);
if (buf) unmap_file(buf);
+ if (fd1 != -1) close(fd1);
continue;
}
