# Release script for Calamares
#
# This attempts to perform the different steps of the RELEASE.md
# document automatically. It's not tested on other machines or
# setups other than [ade]'s development VM.
#
# Assumes that the version in CMakeLists.txt has been bumped,
# and that a release of that version is desired.
#
# None of the "update stuff" is done by this script; in preparation
# for the release, you should have already done:
# - updating the version
# - pulling translations
# - updating the language list
# - switching to the right branch
#
# You can influence the script a little with environment variables:
# - BUILD_DEFAULT set to false to avoid first build with gcc
# - BUILD_CLANG set to false to avoid second build with clang
# - BUILD_ONLY set to true to break after building

### Setup
#
#
BUILDDIR=$(mktemp -d --suffix=-build --tmpdir=.)
### Build with default compiler
#
#
if test "x$BUILD_DEFAULT" = "xtrue" ; then
rm -rf "$BUILDDIR"
mkdir "$BUILDDIR" || { echo "Could not create build directory." ; exit 1 ; }
( cd "$BUILDDIR" && cmake .. && make -j4 ) || { echo "Could not perform test-build." ; exit 1 ; }
( cd "$BUILDDIR" && make test ) || { echo "Tests failed." ; exit 1 ; }
fi
### Build with clang
#
#
if test "x$BUILD_CLANG" = "xtrue" ; then
if which clang++ > /dev/null 2>&1 ; then
# Do build again with clang
rm -rf "$BUILDDIR"
mkdir "$BUILDDIR" || { echo "Could not create build directory." ; exit 1 ; }

( cd "$BUILDDIR" && make test ) || { echo "Tests failed." ; exit 1 ; }
fi

if test "x$BUILD_ONLY" = "xtrue" ; then
echo "Builds completed, release stopped."
exit 1
fi
### Get version number for this release
#
#
V=$( cd "$BUILDDIR" && make show-version | grep ^CALAMARES_VERSION | sed s/^[A-Z_]*=// )
test -n "$V" || { echo "Could not obtain version." ; exit 1 ; }
### Create signed tag
#
# This is the signing key ID associated with the GitHub account adriaandegroot,
# which is used to create all "verified" tags in the Calamares repo.
KEY_ID="128F00873E05AF1D"
git tag -u "$KEY_ID" -m "Release v$V" "v$V" || { echo "Could not sign tag v$V." ; exit 1 ; }
### Create the tarball
#
#
TAR_V="calamares-$V"
TAR_FILE="$TAR_V.tar.gz"
git archive -o "$TAR_FILE" --prefix "$TAR_V/" "v$V" || { echo "Could not create tarball." ; exit 1 ; }
test -f "$TAR_FILE" || { echo "Tarball was not created." ; exit 1 ; }
SHA256=$(sha256sum "$TAR_FILE" | cut -d" " -f1)
### Build the tarball
#
#
D=$(date +%Y%m%d-%H%M%S)
TMPDIR=$(mktemp -d --suffix="-calamares-$D")
test -d "$TMPDIR" || { echo "Could not create tarball-build directory." ; exit 1 ; }
tar xzf "$TAR_FILE" -C "$TMPDIR" || { echo "Could not unpack tarball." ; exit 1 ; }
test -d "$TMPDIR/$TAR_V" || { echo "Tarball did not contain source directory." ; exit 1 ; }
( cd "$TMPDIR/$TAR_V" && cmake . && make -j4 && make test ) || { echo "Tarball build failed." ; exit 1 ; }
### Cleanup
#
rm -rf "$BUILDDIR" # From test-builds
rm -rf "$TMPDIR" # From tarball
### Print subsequent instructions
#
#
cat <<EOF
# Next steps for this release:
git push --tags
gpg -s -u $KEY_ID --detach --armor $TAR_FILE # Sign the tarball
# Upload tarball $TAR_FILE and the signature $TAR_FILE.asc
# Announce via https://github.com/calamares/calamares/releases/new
# SHA256: $SHA256
