Release Process
|
|
====================
|
|
Meta: There should always be a single release engineer to disambiguate responsibility.
|
|
|
|
## Pre-release
|
|
|
|
Check all of the following:
|
|
|
|
- All dependencies have been updated as appropriate:
|
|
- BDB
|
|
- Boost
|
|
- ccache
|
|
- libgmp
|
|
- libsnark (upstream of our fork)
|
|
- libsodium
|
|
- miniupnpc
|
|
- OpenSSL
|
|
|
|
## A. Define the release version as:
|
|
|
|
$ ZCASH_RELEASE=MAJOR.MINOR.REVISION(-BUILD_STRING)
|
|
|
|
Example:
|
|
|
|
$ ZCASH_RELEASE=1.0.0-beta2
|
|
|
|
Also, the following commands use the `ZCASH_RELEASE_PREV` bash variable for the
|
|
previous release:
|
|
|
|
$ ZCASH_RELEASE_PREV=1.0.0-beta1
|
|
|
|
## B. Create a new release branch / github PR
|
|
### B1. Update (commit) version in sources
|
|
|
|
README.md
|
|
src/clientversion.h
|
|
configure.ac
|
|
contrib/DEBIAN/control
|
|
contrib/gitian-descriptors/gitian-linux.yml
|
|
|
|
|
|
In `configure.ac` and `clientversion.h`:
|
|
|
|
- Increment `CLIENT_VERSION_BUILD` according to the following schema:
|
|
|
|
- 0-24: `1.0.0-beta1`-`1.0.0-beta25`
|
|
- 25-49: `1.0.0-rc1`-`1.0.0-rc25`
|
|
- 50: `1.0.0`
|
|
- 51-99: `1.0.0-1`-`1.0.0-49`
|
|
- (`CLIENT_VERSION_REVISION` rolls over)
|
|
- 0-24: `1.0.1-beta1`-`1.0.1-beta25`
|
|
|
|
- Change `CLIENT_VERSION_IS_RELEASE` to false while Zcash is in beta-test phase.
|
|
|
|
### B2. Write release notes
|
|
|
|
git shortlog helps a lot, for example:
|
|
|
|
$ git shortlog --no-merges v${ZCASH_RELEASE_PREV}..HEAD \
|
|
> ./doc/release-notes/release-notes-${ZCASH_RELEASE}.md
|
|
|
|
Update the Debian package changelog:
|
|
|
|
export DEBVERSION="${ZCASH_RELEASE}"
|
|
export DEBEMAIL="${DEBEMAIL:-team@z.cash}"
|
|
export DEBFULLNAME="${DEBFULLNAME:-Zcash Company}"
|
|
|
|
dch -v $DEBVERSION -D jessie -c contrib/DEBIAN/changelog
|
|
|
|
(`dch` comes from the devscripts package.)
|
|
|
|
### B3. Change the network magics
|
|
|
|
If this release breaks backwards compatibility, change the network magic
|
|
numbers. Set the four `pchMessageStart` in `CTestNetParams` in `chainparams.cpp`
|
|
to random values.
|
|
|
|
### B4. Merge the previous changes
|
|
|
|
Do the normal pull-request, review, testing process for this release PR.
|
|
|
|
## C. Verify code artifact hosting
|
|
|
|
### C1. Ensure depends tree is working
|
|
|
|
https://ci.z.cash/builders/depends-sources
|
|
|
|
### C2. Ensure public parameters work
|
|
|
|
Run `./fetch-params.sh`.
|
|
|
|
## D. Make tag for the newly merged result
|
|
|
|
In this example, we ensure master is up to date with the
|
|
previous merged PR, then:
|
|
|
|
$ git tag -s v${ZCASH_RELEASE}
|
|
$ git push origin v${ZCASH_RELEASE}
|
|
|
|
## E. Deploy testnet
|
|
|
|
Notify the Zcash DevOps engineer/sysadmin that the release has been tagged. They update some variables in the company's automation code and then run an Ansible playbook, which:
|
|
|
|
* builds Zcash based on the specified branch
|
|
* deploys it as a public service (e.g. betatestnet.z.cash, mainnet.z.cash)
|
|
* often the same server can be re-used, and the role idempotently handles upgrades, but if not then they also need to update DNS records
|
|
* possible manual steps: blowing away the `testnet3` dir, deleting old parameters, restarting DNS seeder
|
|
|
|
Then, verify that nodes can connect to the testnet server, and update the guide on the wiki to ensure the correct hostname is listed in the recommended zcash.conf.
|
|
|
|
## F. Update the Beta Guide
|
|
## G. Publish the release announcement (blog, zcash-dev, slack)
|
|
## H. Make and deploy deterministic builds
|
|
|
|
- Run the [Gitian deterministic build environment](https://github.com/zcash/zcash-gitian)
|
|
- Compare the uploaded [build manifests on gitian.sigs](https://github.com/zcash/gitian.sigs)
|
|
- If all is well, the DevOps engineer will build the Debian packages and update the
|
|
[apt.z.cash package repository](https://apt.z.cash).
|
|
|
|
## I. Celebrate
|
|
|
|
## missing steps
|
|
Zcash still needs:
|
|
|
|
* thorough pre-release testing (presumably more thorough than standard PR tests)
|
|
|
|
* automated release deployment (e.g.: updating build-depends mirror, deploying testnet, etc...)
