Check env for any default settings, command line options will override these.

if [ -z "$PULL_MTA" ]; then PULL_MTA="sendmail" fi

Prevent environment leakage to these vars.

unset TO unset CC

allow the user to set FROM in the environment

usage() { cat <<EOM Usage: $(basename $0) [-h] [-a] [[-t email]...] -p pull-dir -t email Explicitly add email to the recipients -a Automatically harvest recipients from "*-by: email" lines in the patches in the pull-dir -f Specify a FROM address, you can also use the FROM environment variable. If you do not specify one, it will try to use the one from your git config. This is ignored if -g is used. -g Use git-send-email to send mail instead of sendmail -p pull-dir Directory containing summary and patch files EOM }

Collect To and CC addresses from the patch files if they exist

$1: Which header to add the recipients to, "TO" or "CC"

$2: The regex to match and strip from the line with email addresses

harvest_recipients() { TO_CC=$1 REGX=$2 export IFS=$',\n' for PATCH in $PDIR/*.patch; do # Grab To addresses for EMAIL in $(sed '/^---$/q' $PATCH | grep -e "$REGX" | sed "s/$REGX//"); do if [ "$TO_CC" == "TO" ] && [ "${TO/$EMAIL/}" == "$TO" ] && [ -n "$EMAIL" ]; then if [ -z "$TO" ]; then TO=$EMAIL; else TO="$TO,$EMAIL"; fi elif [ "$TO_CC" == "CC" ] && [ "${CC/$EMAIL/}" == "$CC" ] && [ -n "$EMAIL" ]; then if [ -z "$CC" ]; then CC=$EMAIL; else CC="$CC,$EMAIL"; fi fi done done unset IFS }

Parse and verify arguments

while getopts "af:ghp:t:" OPT; do case $OPT in a) AUTO=1 ;; f) FROM="$OPTARG" ;; g) PULL_MTA="git" ;; h) usage exit 0 ;; p) PDIR=${OPTARG%/} if [ ! -d $PDIR ]; then echo "ERROR: pull-dir "$PDIR" does not exist." usage exit 1 fi ;; t) if [ -n "$TO" ]; then TO="$TO,$OPTARG" else TO="$OPTARG" fi ;; esac done

if [ -z "$PDIR" ]; then echo "ERROR: you must specify a pull-dir." usage exit 1 fi

Verify the cover letter is complete and free of tokens

CL="$PDIR/0000-cover-letter.patch" for TOKEN in SUBJECT BLURB; do grep -q "*** $TOKEN HERE " "$CL" if [ $? -eq 0 ]; then echo "ERROR: Please edit $CL and try again (Look for ' $TOKEN HERE ***')." exit 1 fi done

Harvest emails from the generated patches and populate the TO and CC variables

In addition to To and CC headers/lines, the common Signed-off-by, Tested-by,

etc. (*-by) will be added to CC.

if [ $AUTO -eq 1 ]; then harvest_recipients TO "^[Tt][Oo]: *" harvest_recipients CC "^[Cc][Cc]: " harvest_recipients CC "^.-[Bb][Yy]: *" fi

case "$PULL_MTA" in git) FROM="$(git config sendemail.from)" AUTO_TO="$(git config sendemail.to)" if [ -n "$AUTO_TO" ]; then if [ -n "$TO" ]; then TO="$TO,$AUTO_TO" else TO="$AUTO_TO" fi fi ;; sendmail) if [ -z "$FROM" ]; then FROM="$(git config user.name) <$(git config user.email)>" if [ -z "$FROM" ]; then echo "ERROR: unable to determine a FROM address" usage exit 1 fi fi ;; esac

if [ -z "$TO" ] && [ -z "$CC" ]; then echo "ERROR: you have not specified any recipients." usage exit 1 fi

Generate report for the user and require confirmation before sending

cat <<EOM The following patches: $(for PATCH in $PDIR/*.patch; do echo " $PATCH"; done)

will be sent with the following headers: From: $FROM To: $TO CC: $CC
