      - kres_gnutls_vec_push(): don't uv_write() if ENOMEM
      - tls_client_params_clear(): remove unused function

      daemon/worker: fixes error handling from TLS writes · f52231b6
      Marek Vavruša authored
      The error handling loop for uncorking TLS data was wrong, as the
      underlying push function is asynchronous and there's no relationship
      between completed DNS packet writes and number of TLS message writes.
      In case of the asynchronous function, the buffered data must be valid
      until the write is complete, currently this is not guaranteed and
      loading the resolver with pipelined requests results in memory errors:
      
      ```
      $ getdns_query @127.0.0.1#853 -s -a -s -l L -B -F queries -q

      The current implementation adds opportunistic uv_try_write which
      either writes the requested data, or returns UV_EAGAIN or an error,
      which then falls back to slower asynchronous write that copies the buffered data.
      
      The function signature is changed from simple write to vectorized write.
      
      This also enables TLS False Start to save 1RTT when possible.

      cache: improve out-of-disk condition · efc08a64
      Vladimír Čunát authored
      When suspect SIGBUS happens, print helpful error and try to remove
      the cache, so that the service might work again if auto-restarted.
      Theoretically we could longjmp() out of the SIGBUS handler,
      but that would be rather messy, so let the process die.
