This script is intended to be used to prepare a series of patches

and a cover letter in an appropriate and consistent format for

submission to Open Embedded and The Yocto Project, as well as to

related projects and layers.

ODIR=pull-$$ RELATIVE_TO="master" COMMIT_ID="HEAD" PREFIX="PATCH" RFC=0

usage() { CMD=$(basename $0) cat <<EOM Usage: $CMD [-h] [-o output_dir] [-m msg_body_file] [-s subject] [-r relative_to] [-i commit_id] [-d relative_dir] -u remote [-b branch] -b branch Branch name in the specified remote (default: current branch) -l local branch Local branch name (default: HEAD) -c Create an RFC (Request for Comment) patch series -h Display this help message -a Automatically push local branch (-l) to remote branch (-b), or set CPR_CONTRIB_AUTO_PUSH in env -i commit_id Ending commit (default: HEAD) -m msg_body_file The file containing a blurb to be inserted into the summary email -o output_dir Specify the output directory for the messages (default: pull-PID) -p prefix Use [prefix N/M] instead of [PATCH N/M] as the subject prefix -r relative_to Starting commit (default: master) -s subject The subject to be inserted into the summary email -u remote The git remote where the branch is located, or set CPR_CONTRIB_REMOTE in env -d relative_dir Generate patches relative to directory

Examples: $CMD -u contrib -b nitin/basic $CMD -u contrib -r distro/master -i nitin/distro -b nitin/distro $CMD -u contrib -r distro/master -i nitin/distro -b nitin/distro -l distro $CMD -u contrib -r master -i misc -b nitin/misc -o pull-misc $CMD -u contrib -p "RFC PATCH" -b nitin/experimental $CMD -u contrib -i misc -b nitin/misc -d ./bitbake EOM }

Rewrite private URLs to public URLs

Determine the repository name for use in the WEB_URL later

case "$REMOTE_URL" in @) USER_RE="[A-Za-z0-9_.@][A-Za-z0-9_.@-]$?" PROTO_RE="[a-z][a-z+]://" GIT_RE="(^($PROTO_RE)?$USER_RE@)([^:/])[:/](.)"

if [ -z "$L_BRANCH" ]; then L_BRANCH=HEAD echo "NOTE: Assuming local branch HEAD, use -l to override." fi

if [ $RFC -eq 1 ]; then PREFIX="RFC $PREFIX" fi

Set WEB_URL from known remotes

WEB_URL="" case "$REMOTE_URL" in git.yoctoproject.org) WEB_URL="http://git.yoctoproject.org/cgit.cgi/$REMOTE_REPO/log/?h=$BRANCH" ;; git.pokylinux.org) WEB_URL="http://git.pokylinux.org/cgit.cgi/$REMOTE_REPO/log/?h=$BRANCH" ;; git.openembedded.org) WEB_URL="http://cgit.openembedded.org/$REMOTE_REPO/log/?h=$BRANCH" ;; github.com) WEB_URL="https://github.com/$REMOTE_REPO/tree/$BRANCH" ;; esac

Perform a sanity test on the web URL. Issue a warning if it is not

accessible, but do not abort as users may want to run offline.

if [ -n "$WEB_URL" ]; then if [ "$CPR_CONTRIB_AUTO_PUSH" = "1" ]; then echo "Pushing '$BRANCH' on '$REMOTE' as requested..." git push $REMOTE $L_BRANCH:$BRANCH echo "" fi wget --no-check-certificate -q $WEB_URL -O /dev/null if [ $? -ne 0 ]; then echo "WARNING: Branch '$BRANCH' was not found on the contrib git tree." echo " Please check your remote and branch parameter before sending." echo "" fi fi

if [ -n "$RELDIR" ]; then ODIR=$(realpath $ODIR) pdir=$(pwd) cd $RELDIR extraopts="--relative" fi

Generate the patches and cover letter

git format-patch $extraopts -M40 --subject-prefix="$PREFIX" -n -o $ODIR --thread=shallow --cover-letter $RELATIVE_TO..$COMMIT_ID > /dev/null

if [ -z "$(ls -A $ODIR 2> /dev/null)" ]; then echo "ERROR: $ODIR is empty, no cover letter and patches was generated!" echo " This is most likely due to that $RRELATIVE_TO..$COMMIT_ID" echo " ($RELATIVE_TO..$COMMIT_ID) don't contain any differences." rmdir $ODIR exit 1 fi

[ -n "$RELDIR" ] && cd $pdir

Customize the cover letter

CL="$ODIR/0000-cover-letter.patch" PM="$ODIR/pull-msg" GIT_VERSION=$(git --version | tr -d '[:alpha:][:space:].' | sed 's/....*/\1/') NEWER_GIT_VERSION=210 if [ $GIT_VERSION -lt $NEWER_GIT_VERSION ]; then git request-pull $RELATIVE_TO $REMOTE_URL $COMMIT_ID >> "$PM" else git request-pull $RELATIVE_TO $REMOTE_URL $L_BRANCH:$BRANCH >> "$PM" fi if [ $? -ne 0 ]; then echo "ERROR: git request-pull reported an error" rm -rf $ODIR exit 1 fi

The cover letter already has a diffstat, remove it from the pull-msg

before inserting it.

sed -n "0,#$REMOTE_URL# p" "$PM" | sed -i "/BLURB HERE/ r /dev/stdin" "$CL" rm "$PM"

If this is an RFC, make that clear in the cover letter

if [ $RFC -eq 1 ]; then (cat <<EOM Please review the following changes for suitability for inclusion. If you have any objections or suggestions for improvement, please respond to the patches. If you agree with the changes, please provide your Acked-by.

EOM ) | sed -i "/BLURB HERE/ r /dev/stdin" "$CL" fi

Insert the WEB_URL if there is one

if [ -n "$WEB_URL" ]; then echo " $WEB_URL" | sed -i "#$REMOTE_URL# r /dev/stdin" "$CL" fi

If the user specified a message body, insert it into the cover letter and

remove the BLURB token.

if [ -n "$BODY" ]; then sed -i "/BLURB HERE/ r $BODY" "$CL" sed -i "/BLURB HERE/ d" "$CL" fi

Set subject automatically if there is only one patch

patch_cnt=git log --pretty=oneline ${RELATIVE_TO}..${L_BRANCH} | wc -l if [ -z "$SUBJECT" -a $patch_cnt -eq 1 ]; then SUBJECT="git log --format=%s ${RELATIVE_TO}..${L_BRANCH}" fi

Replace the SUBJECT token with it.

if [ -n "$SUBJECT" ]; then sed -i -e "s/*** SUBJECT HERE ***/$SUBJECT/" "$CL" fi

Generate report for user

cat <<EOM The following patches have been prepared: $(for PATCH in $(ls $ODIR/*); do echo " $PATCH"; done)

Review their content, especially the summary mail: $CL

When you are satisfied, you can send them with: send-pull-request -a -p $ODIR EOM

Check the patches for trailing white space

egrep -q -e "^+.\s+$" $ODIR/ if [ $? -ne 1 ]; then echo echo "WARNING: Trailing white space detected at these locations" egrep -nH --color -e "^+.\s+$" $ODIR/ fi
