=== Launchpad ===

 * https://launchpad.net/~grass
 * [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-experimental/+packages?field.name_filter=grass UbuntuGIS Experimental]
 * [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable/+packages?field.name_filter=grass UbuntuGIS Unstable]

Requirement to upload packages:

 * update OpenGPG to http://keyserver.ubuntu.com and then register OpenGPG in your Launchpad account

=== Git workflow using the GRASS specific branches ===

==== Set up building environment ====

Install requirements:

{{{
sudo apt-get install git-buildpackage dh-python pkg-kde-tools python3-dev
# on Debian also
sudo apt-get install ubuntu-archive-keyring
}}}

===== Set sudo access =====

Run

{{{
sudo visudo
}}}

and add lines bellow:

{{{
# Cmnd alias specification
Cmnd_Alias PBUILDERS=/usr/sbin/pbuilder, /usr/sbin/cowbuilder

# User privilege specification
<username>     ALL=(root)     NOPASSWD:SETENV:PBUILDERS
}}}

===== Configuration file =====

Configuration file for pbuilder (`$HOME/.pbuilderrc`):

{{{
# Optionally set the architecture to the host architecture if none set. Note
# that you can set your own default (i.e. ${ARCH:="i386"}).
###: ${ARCH:="$(dpkg --print-architecture)"}

NAME="$DIST"
if [ -n "${ARCH}" ]; then
    NAME="$NAME-$ARCH"
    DEBOOTSTRAPOPTS=("--arch" "$ARCH" "${DEBOOTSTRAPOPTS[@]}")
fi
BASETGZ="/var/cache/pbuilder/$NAME-base.tgz"
DISTRIBUTION="$DIST"
BUILDRESULT="/var/cache/pbuilder/$NAME/result/"
BUILDPLACE="/var/cache/pbuilder/build/"

DEBOOTSTRAPOPTS=("${DEBOOTSTRAPOPTS[@]}" "--keyring=/usr/share/keyrings/ubuntu-archive-keyring.gpg")
MIRRORSITE="http://cz.archive.ubuntu.com/ubuntu/"
# OTHERMIRROR="deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu $DIST main"
COMPONENTS="main restricted universe multiverse"

BUILDRESULT=${HOME}/tmp/pbuilder-results
HOOKDIR=${HOME}/pbuilder-hooks
EXTRAPACKAGES="${EXTRAPACKAGES} devscripts gnupg patchutils vim-tiny openssh-client lintian"
ALLOWUNTRUSTED=yes
}}}

Define pbuilder hook:

{{{
mkdir $HOME/pbuilder-hooks
echo "#!/bin/bash

set -e

apt -y install gnupg
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6B827C12C2D425E227EDCA75089EBE08314DF160" > $HOME/pbuilder-hooks/G10extra-apt-keys
sudo chmod +x $HOME/pbuilder-hooks/G10extra-apt-keys
}}}

It's a good idea to configure also lintian pbuilder hook:

{{{
cp /usr/share/doc/pbuilder/examples/B90lintian $HOME/pbuilder-hooks/
sed -i 's/lintian -I --show-overrides/& --pedantic -E/; s/^su /##&/; s/^#su /su /' $HOME/pbuilder-hooks/B90lintian
sudo chmod +x $HOME/pbuilder-hooks/B90lintian
}}}

===== Create chroot environment =====

Create specific chroot environment by (example for Ubuntu Bionic - 18.04):

{{{
export DIST=bionic
sudo -E cowbuilder --create --distribution=$DIST --basepath=/var/cache/pbuilder/base-${DIST}-ubuntugis-unstable.cow --save-after-login
}}}

==== Build new package ====

Clone Git repository

{{{
mkdir pkg && cd pkg
# debcheckout --user <username> --git-track '*' grass
git clone https://salsa.debian.org/debian-gis-team/grass.git
cd grass
git remote set-url origin --push git@salsa.debian.org:debian-gis-team/grass.git
}}}

and checkout selected branch (example for Ubuntu Bionic - 18.04):

{{{
export BRANCH=ubuntugis
export PKGNAME=grass
export PATCH=1

export DIST=jammy
export VERSION=7.0.3~rc2
export EXP=~exp1
export NUM=1
}}}

Update tarball:

{{{
git checkout pristine-tar && git pull
git checkout ${BRANCH}/${DIST} && git pull --rebase
}}}

Merge changes related to given tag:

{{{
git merge debian/`echo $VERSION | sed 's/~/_/g'`-${PATCH}`echo $EXP | sed 's/~/_/g'`
# solve changelog conflict issues
git checkout ORIG_HEAD -- debian/gbp.conf 
}}}

Solve conflict in `debian/control` file.

Update changelog:

{{{
# dch -v ${VERSION}-${PATCH}~exp1~${DIST}${NUM}
dch -b -v $(dpkg-parsechangelog | grep Version: | awk -F': ' '{print $2}')~${DIST}${NUM} -D ${DIST} -m "Rebuild for ${DIST}."
}}}

and compare the debian tag to your branch and inspect the diff in the future, it the only changes you should see are the versions for the dependencies and the git branches.

{{{
git add debian/changelog debian/control
git diff --cached debian/changelog debian/control
}}}

Commit changes to Git repository:

{{{
git commit -am"Rebuild $VERSION for $DIST"
}}}

Build package:

{{{
gbp buildpackage --git-pbuilder-options=--source-only-changes -sa --git-pbuilder --git-dist=${DIST}-ubuntugis-experimental >../log.packager-$DIST 2>&1
}}}

Note1: use `-sa` only when build/uploading first package for GRASS version

Note2: replace `--git-pbuilder-options=--source-only-changes` by `-S` when using older versions of `gbp`
 
Note3: all lintian issues of severity info (I:) and higher need to be reviewed and fixed before the upload 

{{{
cat ../log.packager-$DIST | awk '/+++ lintian output +++/,/+++ end of lintian output +++/' | grep -v ^+++
}}}

Tag release version in Git repository:

{{{
git tag $BRANCH/`echo $VERSION | sed 's/~/_/g'`-${PATCH}`echo $EXP | sed 's/~/_/g'`.${DIST}${NUM}
}}}

Push changes:

{{{
git push origin --set-upstream ; git push origin --tags
}}}

==== Upload to Launchpad ====

Configuration file `~/.dput.cf`:

{{{
[ubuntugis-experimental]
fqdn = ppa.launchpad.net
method = ftp
incoming = ~ubuntugis/ubuntugis-experimental/ubuntu/
login = <yours-launchpad-id>
allow_unsigned_uploads = 0
}}}

Remove buildinfo lines:

{{{
sed -i '/buildinfo/d' ../${PKGNAME}_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}_source.changes
}}}

Sign created package

{{{
debsign ../${PKGNAME}_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}_source.changes
}}}

and upload to Launchpad:

{{{
dput ubuntugis-experimental ../${PKGNAME}_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}_source.changes
}}}

At the end local files can be removed:

{{{
rm -v ../${PKGNAME}_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}*
}}}
==== Notes ====

===== Create new branch for Ubuntu version =====

Create a new branch if not exists:

{{{
git checkout -b ${BRANCH}/${DIST} debian/`echo $VERSION | sed 's/~/_/g'`-${PATCH}
git push origin ${BRANCH}/${DIST}
}}}

Update branch in gbp.conf & Vcs-Git URL, see [https://salsa.debian.org/debian-gis-team/grass/-/commit/f92184206d63561bd2e3e85dd566ec25dafcaa1e example].

===== Copy packages from Expr to Unstable PPA =====

* https://launchpad.net/%7Eubuntugis/+archive/ubuntu/ubuntugis-experimental/+copy-packages
=== Build package from tarball ===

'''Warning:''' this part is out-dated, use ''Git workflow using the GRASS specific branches'' instead.
