RELEASE.md

Upstream

• prepare the environment:

    export VERSION=x.y.z

• update configure.ac and ChangeLog

    perl -pi -E \
       "s{^AC_INIT\(\[backupninja\],\[[0-9.]+\],}{AC_INIT([backupninja],[$VERSION],}" \
       configure.ac && \
    RELEASE_DATE=$(LC_ALL=C date '+%B %d, %Y') perl -pi -E \
       "s{^version\s+[0-9.]+\s+--\s+UNRELEASED$}{version $VERSION -- $RELEASE_DATE}" \
       ChangeLog

• commit, tag and create the tarball:

    git commit configure.ac ChangeLog \
        -m "Releasing backupninja $VERSION" && \
    git clean -fdx && \
    git tag -s "backupninja-$VERSION" \
        -m "Releasing backupninja $VERSION" && \
    ./autogen.sh && \
    ./configure && \
    make dist

• compare the content of the generated tarball with the content of the previous one

• move the tarball outside of the Git working copy and clean up:

    mkdir -p ../tarballs && \
    mv backupninja-$VERSION.tar.gz ../tarballs/ && \
    make distclean && \
    git clean -fdx

• Install (extract tarball, .configure && make && sudo make install) and test.

Debian

Prepare a new package:

    git checkout debian && \
    gbp import-orig --upstream-vcs-tag="backupninja-$VERSION" \
        ../tarballs/backupninja-$VERSION.tar.gz && \
    gbp dch --auto && \
    dch -e && \
    export DEBIAN_VERSION=$(dpkg-parsechangelog -SVersion) && \
    git commit debian/changelog \
       -m "Releasing backupninja ($DEBIAN_VERSION) to Debian unstable" && \
    gbp buildpackage

Install the .deb and test.

Release

• sign the release and push it to Git:

    gpg --armor --detach-sign \
        ../tarballs/backupninja-$VERSION.tar.gz && \
    git checkout debian && \
    gbp buildpackage --git-tag-only --git-sign-tags && \
    git push --follow-tags origin \
        master:master \
        debian:debian \
        pristine-tar:pristine-tar \
        upstream:upstream

• upload the upstream tarball and detached signature to the GitLab milestone page with Edit → Attach a file

• announce the release on the backupninja mailing-list, pointing to the milestone web page

• upload to Debian or ask someone listed in the Uploaders control field to review and upload

Open the next development cycle

• git checkout master
• Add an empty new section in ChangeLog, commit and push.
