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

Prevent environment leakage to these vars.

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 "aghp:t:" OPT; do case $OPT in a) AUTO=1 ;; g) PULL_MTA="git" ;; h) usage exit 0 ;; p) PDIR=${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

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 to the following recipients: To: $TO CC: $CC
