havepatch: new script to easily check if a mailed patch is applied Right now this only works on the hg repo, and it assumes the patch was applied as a descendant of 3.5 to keep the checks quick. In a perfect world I'd be able to do this all with obsolete marker checks, but that doesn't seem to be a good option yet.

function certfor() {
  if [ "x$1" = "x" ] ; then
    echo 'abort: specify host:port pair as argument'
    return 1
  fi
  openssl x509 -in <(echo | openssl s_client -showcerts -connect $1 | \
    awk '/-----BEGIN CERTIFICATE-----/,/-----END CERTIFICATE-----/') -noout -text
}
