- Thomas Lopatic fixed the alarm()-based DNS timeout:
Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in
case of a timeout, the signal handler for SIGALRM never gets removed. I
think that in my case it gets executed at some point later on when execution
has long left Curl_resolv_timeout() or even the cURL library.
The code that is jumped to with siglongjmp() simply sets the error message
to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess
that instead of simply returning without cleaning up, the code should have a
goto that jumps to the spot right after the call to Curl_resolv().
