Release Process

Before every release candidate:

  • Update version in configure.ac (don't forget to set CLIENT_VERSION_IS_RELEASE to true)
  • Write release notes to changelog

Before every major release:

  • Update hardcoded, see this pull request for an example.
  • Update version of contrib/gitian-descriptors/*.yml: usually one'd want to do this on master after branching off the release - but be sure to at least do it before a new major release

First time / New builders

If you're using the automated script (found in contrib/gitian-build.sh), then at this point you should run it with the "--setup" command. Otherwise ignore this.

Check out the source code in the following directory hierarchy.

cd /path/to/your/toplevel/build
git clone https://github.com/gridcoin-community/gitian.sigs.git
git clone https://github.com/bitcoin-core/bitcoin-detached-sigs.git
git clone https://github.com/devrandom/gitian-builder.git
git clone https://github.com/gridcoin/Gridcoin-Research.git

Gridcoin maintainers/release engineers, suggestion for writing release notes

Write release notes. git shortlog helps a lot, for example:

git shortlog --no-merges v(current version, e.g. 0.7.2)..v(new version, e.g. 0.8.0)

Generate list of authors:

git log --format='%aN' "$*" | sort -ui | sed -e 's/^/- /'

Tag version (or release candidate) in git

git tag -s v(new version, e.g. 0.8.0)

Setup and perform Gitian builds

If you're using the automated script (found in contrib/gitian-build.sh), then at this point you should run it with the "--build" command. Otherwise ignore this.

Setup Gitian descriptors:

pushd ./Gridcoin-Research
export SIGNER=(your Gitian key, ie bluematt, sipa, etc)
export VERSION=(new version, e.g. 0.8.0)
git fetch
git checkout v${VERSION}
popd

Ensure your gitian.sigs are up-to-date if you wish to gverify your builds against other Gitian signatures.

pushd ./gitian.sigs
git pull
popd

Ensure gitian-builder is up-to-date:

pushd ./gitian-builder
git pull
popd

Fetch and create inputs: (first time, or when dependency versions change)

pushd ./gitian-builder
mkdir -p inputs
wget -P inputs https://bitcoincore.org/cfields/osslsigncode-Backports-to-1.7.1.patch
wget -P inputs http://downloads.sourceforge.net/project/osslsigncode/osslsigncode/osslsigncode-1.7.1.tar.gz
popd

Create the OS X SDK tarball, see the OS X readme for details, and copy it into the inputs directory.

Optional: Seed the Gitian sources cache and offline git repositories

By default, Gitian will fetch source files as needed. To cache them ahead of time:

pushd ./gitian-builder
make -C ../Gridcoin-Research/depends download SOURCES_PATH=`pwd`/cache/common
popd

Only missing files will be fetched, so this is safe to re-run for each build.

NOTE: Offline builds must use the --url flag to ensure Gitian fetches only from local URLs. For example:

pushd ./gitian-builder
./bin/gbuild --url gridcoin=/path/to/gridcoin,signature=/path/to/sigs {rest of arguments}
popd

The gbuild invocations below DO NOT DO THIS by default.

Build and sign Gridcoin Wallet for Linux, Windows, and OS X:

pushd ./gitian-builder
./bin/gbuild --num-make 2 --memory 3000 --commit gridcoin=v${VERSION} ../Gridcoin-Research/contrib/gitian-descriptors/gitian-linux.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-linux --destination ../gitian.sigs/ ../Gridcoin-Research/contrib/gitian-descriptors/gitian-linux.yml
mv build/out/gridcoin-*.tar.gz build/out/src/gridcoin-*.tar.gz ../

./bin/gbuild --num-make 2 --memory 3000 --commit gridcoin=v${VERSION} ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-win-unsigned --destination ../gitian.sigs/ ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win.yml
mv build/out/gridcoin-*-win-unsigned.tar.gz inputs/gridcoin-win-unsigned.tar.gz
mv build/out/gridcoin-*.zip build/out/gridcoin-*.exe ../

./bin/gbuild --num-make 2 --memory 3000 --commit gridcoin=v${VERSION} ../gridcoin/contrib/gitian-descriptors/gitian-osx.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-osx-unsigned --destination ../gitian.sigs/ ../gridcoin/contrib/gitian-descriptors/gitian-osx.yml
mv build/out/gridcoin-*-osx-unsigned.tar.gz inputs/gridcoin-osx-unsigned.tar.gz
mv build/out/gridcoin-*.tar.gz build/out/gridcoin-*.dmg ../
popd

Build output expected:

  1. source tarball (gridcoin-${VERSION}.tar.gz)
  2. linux 32-bit and 64-bit dist tarballs (gridcoin-${VERSION}-linux[32|64].tar.gz)
  3. windows 32-bit and 64-bit unsigned installers and dist zips (gridcoin-${VERSION}-win[32|64]-setup-unsigned.exe, gridcoin-${VERSION}-win[32|64].zip)
  4. OS X unsigned installer and dist tarball (gridcoin-${VERSION}-osx-unsigned.dmg, gridcoin-${VERSION}-osx64.tar.gz)
  5. Gitian signatures (in gitian.sigs/${VERSION}-<linux|{win,osx}-unsigned>/(your Gitian key)/)

Verify other gitian builders signatures to your own. (Optional)

Add other gitian builders keys to your gpg keyring, and/or refresh keys.

gpg --import gridcoin/contrib/gitian-keys/*.pgp
gpg --refresh-keys

Verify the signatures

pushd ./gitian-builder
./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-linux ../Gridcoin-Research/contrib/gitian-descriptors/gitian-linux.yml
./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-win-unsigned ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win.yml
./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-osx-unsigned ../Gridcoin-Research/contrib/gitian-descriptors/gitian-osx.yml
popd

Next steps:

Commit your signature to gitian.sigs:

pushd gitian.sigs
git add ${VERSION}-linux/${SIGNER}
git add ${VERSION}-win-unsigned/${SIGNER}
git add ${VERSION}-osx-unsigned/${SIGNER}
git commit -a
git push  # Assuming you can push to the gitian.sigs tree
popd

Codesigner only: Create Windows/OS X detached signatures:

  • Only one person handles codesigning. Everyone else should skip to the next step.
  • Only once the Windows/OS X builds each have 3 matching signatures may they be signed with their respective release keys.

Codesigner only: Sign the osx binary:

transfer gridcoin-osx-unsigned.tar.gz to osx for signing
tar xf gridcoin-osx-unsigned.tar.gz
./detached-sig-create.sh -s "Key ID"
Enter the keychain password and authorize the signature
Move signature-osx.tar.gz back to the gitian host

Codesigner only: Sign the windows binaries:

tar xf gridcoin-win-unsigned.tar.gz
./detached-sig-create.sh -key /path/to/codesign.key
Enter the passphrase for the key when prompted
signature-win.tar.gz will be created

Codesigner only: Commit the detached codesign payloads:

cd ~/gridcoin-detached-sigs
checkout the appropriate branch for this release series
rm -rf *
tar xf signature-osx.tar.gz
tar xf signature-win.tar.gz
git add -a
git commit -m "point to ${VERSION}"
git tag -s v${VERSION} HEAD
git push the current branch and new tag

Non-codesigners: wait for Windows/OS X detached signatures:

  • Once the Windows/OS X builds each have 3 matching signatures, they will be signed with their respective release keys.
  • Detached signatures will then be committed to the gridcoin-detached-sigs repository, which can be combined with the unsigned apps to create signed binaries.

Create (and optionally verify) the signed OS X binary:

pushd ./gitian-builder
./bin/gbuild -i --commit signature=v${VERSION} ../gridcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-osx-signed --destination ../gitian.sigs/ ../gridcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-osx-signed ../gridcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
mv build/out/gridcoin-osx-signed.dmg ../gridcoin-${VERSION}-osx.dmg
popd

Create (and optionally verify) the signed Windows binaries:

pushd ./gitian-builder
./bin/gbuild -i --commit signature=v${VERSION} ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win-signer.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-win-signed --destination ../gitian.sigs/ ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win-signer.yml
./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-win-signed ../Gridcoin-Research/contrib/gitian-descriptors/gitian-win-signer.yml
mv build/out/gridcoin-*win64-setup.exe ../gridcoin-${VERSION}-win64-setup.exe
mv build/out/gridcoin-*win32-setup.exe ../gridcoin-${VERSION}-win32-setup.exe
popd

Commit your signature for the signed OS X/Windows binaries:

pushd gitian.sigs
git add ${VERSION}-osx-signed/${SIGNER}
git add ${VERSION}-win-signed/${SIGNER}
git commit -a
git push  # Assuming you can push to the gitian.sigs tree
popd

After 3 or more people have gitian-built and their results match:

  • Create SHA256SUMS.asc for the builds, and GPG-sign it:
sha256sum * > SHA256SUMS

The list of files should be:

gridcoin-${VERSION}-aarch64-linux-gnu.tar.gz
gridcoin-${VERSION}-arm-linux-gnueabihf.tar.gz
gridcoin-${VERSION}-i686-pc-linux-gnu.tar.gz
gridcoin-${VERSION}-x86_64-linux-gnu.tar.gz
gridcoin-${VERSION}-osx64.tar.gz
gridcoin-${VERSION}-osx.dmg
gridcoin-${VERSION}.tar.gz
gridcoin-${VERSION}-win32-setup.exe
gridcoin-${VERSION}-win32.zip
gridcoin-${VERSION}-win64-setup.exe
gridcoin-${VERSION}-win64.zip

The *-debug* files generated by the gitian build contain debug symbols for troubleshooting by developers. It is assumed that anyone that is interested in debugging can run gitian to generate the files for themselves. To avoid end-user confusion about which file to pick, as well as save storage space do not upload these to the gridcoin.us server, nor put them in the torrent.

  • GPG-sign it, delete the unsigned file:
gpg --digest-algo sha256 --clearsign SHA256SUMS # outputs SHA256SUMS.asc
rm SHA256SUMS

  • Announce the release:

    • Cryptocurrencytalk post

    • Update title of #gridcoin on Freenode IRC

    • Twitter, reddit /r/Gridcoin and Slack

    • Create a new GitHub release with a link to the archived release notes.

    • Celebrate
