Release Process |
# Hush Release Process |
||||
==================== |
|
||||
Meta: There should always be a single release engineer to disambiguate responsibility. |
|
||||
|
|
||||
If this is a hotfix release, please see `./hotfix-process.md` before proceeding. |

### Github Milestone |
### Github Issues |
||||
|
|
||||
Ensure all goals for the github milestone are met. If not, remove tickets |
Looks for Github issues that should be fixed in the next release. |
||||
or PRs with a comment as to why it is not included. (Running out of time |
|
||||
is a common reason.) |

### Pre-release checklist: |
### Pre-release checklist: |
||||
|
|
||||
Check that dependencies are properly hosted by looking at the `check-depends` builder: |
... |
||||
|
|
||||
https://ci.z.cash/#/builders/1 |
|
||||
|
|
||||
Check that there are no surprising performance regressions: |
|
||||
|
|
||||
https://speed.z.cash |
|
||||
|
|
||||
Ensure that new performance metrics appear on that site. |
|
||||
|
|
||||
Update `src/chainparams.cpp` nMinimumChainWork with information from the getblockchaininfo rpc. |
|
||||
|
|
||||
### Protocol Safety Checks: |
### Protocol Safety Checks: |
||||
|
|
||||
If this release changes the behavior of the protocol or fixes a serious |
|
||||
bug, verify that a pre-release PR merge updated `PROTOCOL_VERSION` in |
|
||||
`version.h` correctly. |
|
||||
|
|
||||
If this release breaks backwards compatibility or needs to prevent |
|
||||
interaction with software forked projects, change the network magic |
|
||||
numbers. Set the four `pchMessageStart` in `CTestNetParams` in |
|
||||
`chainparams.cpp` to random values. |
|
||||
|
|
||||
Both of these should be done in standard PRs ahead of the release |
|
||||
process. If these were not anticipated correctly, this could block the |
|
||||
release, so if you suspect this is necessary, double check with the |
|
||||
whole engineering team. |

||||

## Release process |
## Release process |
||||
|
|
||||
In the commands below, <RELEASE> and <RELEASE_PREV> are prefixed with a v, ie. |
... |
||||
v1.0.9 (not 1.0.9). |
|
||||
|
|
||||
### Create the release branch |
|
||||
|
|
||||
Run the release script, which will verify you are on the latest clean |
|
||||
checkout of master, create a branch, then commit standard automated |
|
||||
changes to that branch locally: |
|
||||
|
|
||||
$ ./zcutil/make-release.py <RELEASE> <RELEASE_PREV> <RELEASE_FROM> <APPROX_RELEASE_HEIGHT> |
|
||||
|
|
||||
Examples: |
|
||||
|
|
||||
$ ./zcutil/make-release.py v1.0.9 v1.0.8-1 v1.0.8-1 120000 |
|
||||
$ ./zcutil/make-release.py v1.0.13 v1.0.13-rc1 v1.0.12 222900 |
|
||||
|
|
||||
### Create, Review, and Merge the release branch pull request |
|
||||
|
|
||||
Review the automated changes in git: |
|
||||
|
|
||||
$ git log master..HEAD |
|
||||
|
|
||||
Push the resulting branch to github: |
|
||||
|
|
||||
$ git push 'git@github.com:$YOUR_GITHUB_NAME/zcash' $(git rev-parse --abbrev-ref HEAD) |
|
||||
|
|
||||
Then create the PR on github. Complete the standard review process, |
|
||||
then merge, then wait for CI to complete. |
|
||||
|
|
||||
## Make tag for the newly merged result |
|
||||
|
|
||||
Checkout master and pull the latest version to ensure master is up to date with the release PR which was merged in before. |
|
||||
|
|
||||
$ git checkout master |
|
||||
$ git pull --ff-only |
|
||||
|
|
||||
Check the last commit on the local and remote versions of master to make sure they are the same: |
|
||||
|
|
||||
$ git log -1 |
|
||||
|
|
||||
The output should include something like, which is created by Homu: |
|
||||
|
|
||||
Auto merge of #4242 - nathan-at-least:release-v1.0.9, r=nathan-at-least |
|
||||
|
|
||||
Then create the git tag. The `-s` means the release tag will be |
|
||||
signed. **CAUTION:** Remember the `v` at the beginning here: |
|
||||
|
|
||||
$ git tag -s v1.0.9 |
|
||||
$ git push origin v1.0.9 |
|
||||
|
|
||||
## 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). |
|
||||
|
|
||||
## Add release notes to GitHub |
|
||||
|
|
||||
- Go to the [GitHub tags page](https://github.com/zcash/zcash/tags). |
|
||||
- Click "Add release notes" beside the tag for this release. |
|
||||
- Copy the release blog post into the release description, and edit to suit |
|
||||
publication on GitHub. See previous release notes for examples. |
|
||||
- Click "Publish release" if publishing the release blog post now, or |
|
||||
"Save draft" to store the notes internally (and then return later to publish |
|
||||
once the blog post is up). |
|
||||
|
|
||||
Note that some GitHub releases are marked as "Verified", and others as |
|
||||
"Unverified". This is related to the GPG signature on the release tag - in |
|
||||
particular, GitHub needs the corresponding public key to be uploaded to a |
|
||||
corresponding GitHub account. If this release is marked as "Unverified", click |
|
||||
the marking to see what GitHub wants to be done. |
|
||||
|
|
||||
## Post Release Task List |
|
||||
|
|
||||
### 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. |
|
||||
|
|
||||
### Update the 1.0 User Guide |
|
||||
|
|
||||
This also means updating [the translations](https://github.com/zcash/zcash-docs). |
|
||||
Coordinate with the translation team for now. Suggestions for improving this |
|
||||
part of the process should be added to #2596. |
|
||||
|
|
||||
### Publish the release announcement (blog, github, zcash-dev, slack) |
