Html5Depurate/Updating apt.wikimedia.org

How to update the html5depurate package in apt.wikimedia.org:

Setup

• git clone https://gerrit.wikimedia.org/r/mediawiki/services/html5depurate
• Get pbuilder, devscripts, dupload
• Create pbuilder roots

sudo pbuilder --create \
  --basetgz /var/cache/pbuilder/jessie.tgz \
  --distribution jessie \
  --mirror <debian-mirror>

sudo pbuilder --create \
   --basetgz /var/cache/pbuilder/trusty.tgz \
   --distribution trusty \
   --components 'main universe' \
   --mirror <trusty-mirror>

• Get the debian branches

git branch debian gerrit/debian
git branch debian-trusty gerrit/debian-trusty

Update git branches

• Merge changes from master and resolve conflicts

git checkout debian
git merge master
git commit --amend -C HEAD

• Add a changelog entry (the package version comes from here)

dch
git commit -a -m "Changelog for package version x.y.z"
git review debian

• Merge changes from debian into debian-trusty

git checkout debian-trusty
git merge debian
git commit --amend -C HEAD
dch
git commit -a -m "Changelog for package x.y.z~trusty"
git review debian-trusty

Build and upload

I've automated the rest:

#!/bin/bash
set -e

srcdir=~/src/wmf/mediawiki/services/html5depurate

# Test SSH connection
ssh carbon.wikimedia.org true

tmpdir=~/tmp/pbuilder
mkdir -p "$tmpdir" || true
tmpsrcdir=$(mktemp -d --tmpdir="$tmpdir")
cd "$tmpsrcdir"
git clone -b debian "$srcdir" html5depurate
jessiedsc=$(dpkg-source -b html5depurate | perl -ne 'if (/(html5depurate_.*\.dsc)/) {print "$1\n";}')
sudo pbuilder --build \
	--basetgz /var/cache/pbuilder/jessie.tgz \
   	--configfile html5depurate/debian/pbuilderrc \
	$jessiedsc

cd html5depurate
git checkout debian-trusty
cd ..
trustydsc=$(dpkg-source -b html5depurate | perl -ne 'if (/(html5depurate_.*\.dsc)/) {print "$1\n";}')
sudo pbuilder --build \
	--basetgz /var/cache/pbuilder/trusty.tgz \
   	--configfile html5depurate/debian/pbuilderrc \
	$trustydsc

cd /var/cache/pbuilder/result

jessiechanges=${jessiedsc%.dsc}_amd64.changes
trustychanges=${trustydsc%.dsc}_amd64.changes

debsign $jessiechanges
debsign $trustychanges
dupload --nomail $jessiechanges
dupload --nomail $trustychanges

ssh carbon.wikimedia.org "
	set -ve
	cd /srv/wikimedia/incoming
	export REPREPRO_BASE_DIR=/srv/wikimedia
	export GNUPGHOME=/root/.gnupg
	sudo -E reprepro -C main --ignore wrongdistribution include jessie-wikimedia $jessiechanges
	sudo -E reprepro -C main --ignore wrongdistribution include trusty-wikimedia $trustychanges
"

rm -rf "$tmpsrcdir"
