Praat backports website

Create the signing GnuPG key

On my laptop:

gpg --full-generate-key
KEY=$(gpg --list-key "praat backports" | grep "^      ")
git clone rlaboiss@git.cefala.org:/var/git/rlaboiss/praat-backports
cd praat-backports
gpg --armor --export $KEY > www/praat.gpg.key
git commit -m 'New signing key'

On the build system (dev.cefala.org):

git clone rlaboiss@git.cefala.org:/var/git/rlaboiss/praat-backports
cd praat-backports
gpg --import www/praat.gpg.key

Update the pbuilder images

On the build system (dev.cefala.org):

DIST=stable ARCH=i386 sudo pbuilder --update
DIST=stable ARCH=amd64 sudo pbuilder --update

It is necessary to ensure that the file /etc/apt/sources.list does not contain hardcoded distribution names, for instance:

deb http://ftp.us.debian.org/debian/ stable-backports main contrib non-free
deb http://ftp.us.debian.org/debian/ stable main contrib non-free

When a new Debian distribution is released, it is necessary to explicitly accept the change the codename change, for instance:

$ ARCH=i386 DIST=stable sudo pbuilder --login --save-after-login
root@dev:/# apt update
N: Repository 'http://ftp.us.debian.org/debian stable InRelease' changed its 'Version' value from '12.11' to '13.1'
E: Repository 'http://ftp.us.debian.org/debian stable InRelease' changed its 'Codename' value from 'bookworm' to 'trixie'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
Do you want to accept these changes and continue updating from this repository? [y/N] y

Build the packages

On the build system (dev.cefala.org):

distrib=trixie
debian_version=13
version_trixie=6.4.27+dfsg-2
version_testing=6.4.47+dfsg-1
version_backported=$version_testing~bpo$debian_version+1
gbp clone git@salsa.debian.org:med-team/praat.git praat-backports
cd praat-backports
git checkout -b $distrib debian/$version_trixie # version in trixie
git merge debian/$version_testing # last release in testing

Create a debian/changelog entry with:

cat > /var/tmp/new-entry <<EOF
praat ($version_backported) $distrib; urgency=medium

  * Backported to $distrib

 -- 

EOF
cat >> /var/tmp/new-entry debian/changelog
mv /var/tmp/new-entry debian/changelog
emacsclient -nw debian/changelog

Build the packages for both i386 and amd64 architectures:

DIST=stable ARCH=i386 DEB_BUILD_OPTIONS=nocheck pdebuild --debbuildopts "-b -us -uc"
DIST=stable ARCH=amd64 DEB_BUILD_OPTIONS=nocheck pdebuild --debbuildopts "-b -us -uc"

Setup the website

On the http system (www.cefala.org):

git clone rlaboiss@git.cefala.org:/var/git/rlaboiss/praat-backports
cd praat-backports
make install-www

Populate the repository

On the build system (dev.cefala.org):

make clean
make
cd repo
for pkg in praat praat-doc ; do
    for arch in i386 amd64 ; do
        bin/add-pkg.sh  \
            $distrib    \
            /var/cache/pbuilder/stable-$arch/result/${pkg}_${version_backported}_*.deb
    done
done
make -C.. install-repo
