## Versioning
|
|
|
|
### Which Crates to Increment
|
|
|
|
To check if any of the top-level crates need version increments:
|
|
1. Go to the zebra GitHub code page: https://github.com/ZcashFoundation/zebra
|
|
2. Check if the last commit was a Zebra version bump, or something else
|
|
|
|
<details>
|
|
|
|
Alternatively you can:
|
|
- Use the github compare tool and check the `main` branch against the last tag ([Example](https://github.com/ZcashFoundation/zebra/compare/v1.0.0-alpha.15...main))
|
|
- Use `git diff --stat <previous-release-tag> origin/main`
|
|
|
|
</details>
|
|
|
|
Once you know which crates have changed:
|
|
- [ ] Increment the crates that have new commits since the last version update
|
|
- [ ] Increment any crates that depend on crates that have changed
|
|
- [ ] Keep a list of the crates that haven't been incremented, to include in the PR
|
|
|
|
### How to Increment Versions
|
|
|
|
Zebra follows [semantic versioning](https://semver.org).
|
|
|
|
Semantic versions look like: MAJOR`.`MINOR`.`PATCH[`-`TAG`.`PRE-RELEASE]
|
|
|
|
<details>
|
|
|
|
#### Pre-Release Crates
|
|
|
|
Pre-Release versions have a `TAG` like "alpha" or "beta". For example: `1.0.0-alpha.0`
|
|
|
|
1. Increment the `PRE-RELEASE` version for the crate.
|
|
|
|
#### Unstable Crates
|
|
|
|
Unstable versions have a `MAJOR` version of zero. For example: `0.1.0`
|
|
|
|
1. Follow stable crate versioning, but increment the `MINOR` version for breaking changes
|
|
|
|
#### Stable Crates
|
|
|
|
For example: `1.0.0`
|
|
|
|
Increment the first version component in this list, and reset the other components to zero:
|
|
1. MAJOR versions for breaking public API changes and removals
|
|
* check for types from dependencies that appear in the public API
|
|
2. MINOR versions for new features
|
|
3. PATCH versions for bug fixes
|
|
* includes dependency updates that don't impact the public API
|
|
|
|
### Reviewing Version Bumps
|
|
|
|
Check for missed changes by going to:
|
|
`https://github.com/ZcashFoundation/zebra/tree/<commit-hash>/`
|
|
Where `<commit-hash>` is the hash of the last commit in the version bump PR.
|
|
|
|
If any Zebra or Tower crates have commit messages that are **not** a version bump, we have missed an update.
|
|
Also check for crates that depend on crates that have changed. They should get a version bump as well.
|
|
|
|
</details>
|
|
|
|
### Version Locations
|
|
|
|
Once you know which versions you want to increment, you can find them in the:
|
|
- [ ] zebra* `Cargo.toml`s
|
|
- [ ] tower-* `Cargo.toml`s
|
|
- [ ] `zebra-network` protocol user agent: https://github.com/ZcashFoundation/zebra/blob/main/zebra-network/src/constants.rs
|
|
- [ ] `README.md`
|
|
- [ ] `book/src/user/install.md`
|
|
- [ ] `Cargo.lock`: automatically generated by `cargo build`
|
|
|
|
#### Version Tooling
|
|
|
|
You can use `fastmod` to interactively find and replace versions.
|
|
|
|
For example, you can do something like:
|
|
```
|
|
fastmod --extensions rs,toml,md --fixed-strings '1.0.0-beta.11' '1.0.0-beta.12'
|
|
fastmod --extensions rs,toml,md --fixed-strings '0.2.26' '0.2.27' tower-batch tower-fallback
|
|
```
|
|
|
|
If you use `fastmod`, don't update versions in `CHANGELOG.md`.
|
|
|
|
## README
|
|
|
|
We should update the README to:
|
|
- [ ] Remove any "Known Issues" that have been fixed
|
|
- [ ] Update the "Build and Run Instructions" with any new dependencies.
|
|
Check for changes in the `Dockerfile` since the last tag: `git diff <previous-release-tag> docker/Dockerfile`.
|
|
|
|
## Change Log
|
|
|
|
**Important**: Any merge into `main` deletes any edits to the draft changelog.
|
|
Once you are ready to tag a release, copy the draft changelog into `CHANGELOG.md`.
|
|
|
|
We follow the [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) format.
|
|
|
|
We use [the Release Drafter workflow](https://github.com/marketplace/actions/release-drafter) to automatically create a [draft changelog](https://github.com/ZcashFoundation/zebra/releases).
|
|
|
|
To create the final change log:
|
|
- [ ] Copy the draft changelog into `CHANGELOG.md`
|
|
- [ ] Delete any trivial changes. Keep the list of those, to include in the PR
|
|
- [ ] Combine duplicate changes
|
|
- [ ] Edit change descriptions so they are consistent, and make sense to non-developers
|
|
- [ ] Check the category for each change
|
|
- Prefer the "Fix" category if you're not sure
|
|
|
|
<details>
|
|
|
|
#### Change Categories
|
|
|
|
From "Keep a Changelog":
|
|
* `Added` for new features.
|
|
* `Changed` for changes in existing functionality.
|
|
* `Deprecated` for soon-to-be removed features.
|
|
* `Removed` for now removed features.
|
|
* `Fixed` for any bug fixes.
|
|
* `Security` in case of vulnerabilities.

## Create the Release
|
|
|
|
### Create the Release PR
|
|
|
|
After you have the version increments and the updated changelog:
|
|
|
|
- [ ] Push the version increments and the updated changelog into a branch
|
|
(name suggestion, example: `v1.0.0-alpha.0-release`)
|
|
- [ ] Create a release PR by adding `&template=release-checklist.md` to the
|
|
comparing url ([Example](https://github.com/ZcashFoundation/zebra/compare/v1.0.0-alpha.0-release?expand=1&template=release-checklist.md)).
|
|
- [ ] Add the list of deleted changelog entries as a comment to make reviewing easier.
|
|
- [ ] Also add the list of not-bumped crates as a comment (can use the same comment as the previous one).
|
|
- [ ] Turn on [Merge Freeze](https://www.mergefreeze.com/installations/3676/branches).
|
|
- [ ] Once the PR is ready to be merged, unfreeze it [here](https://www.mergefreeze.com/installations/3676/branches).
|
|
Do not unfreeze the whole repository.
|
|
|
|
### Create the Release
|
|
|
|
- [ ] Once the PR has been merged,
|
|
create a new release using the draft release as a base,
|
|
by clicking the Edit icon in the [draft release](https://github.com/ZcashFoundation/zebra/releases)
|
|
- [ ] Set the tag name to the version tag,
|
|
for example: `v1.0.0-alpha.0`
|
|
- [ ] Set the release to target the `main` branch
|
|
- [ ] Set the release title to `Zebra ` followed by the version tag,
|
|
for example: `Zebra 1.0.0-alpha.0`
|
|
- [ ] Copy the final changelog of this release to the release description
|
|
(starting just _after_ the title `## [Zebra ...`)
|
|
- [ ] Mark the release as 'pre-release' (until we are no longer alpha/beta)
|
|
- [ ] Publish the release
|
|
|
|
## Final Testing
|
|
|
|
- [ ] After tagging the release, test that the exact `cargo install` command in `README.md` works
|
|
(`--git` behaves a bit differently to `--path`)
|
|
- [ ] Turn off [Merge Freeze](https://www.mergefreeze.com/installations/3676/branches) for the whole repository
|
|
|
|
If the build fails after tagging:
|
|
1. Fix the build
|
|
2. Increment versions again, following these instructions from the start
|
|
3. Update `README.md` with a **new** git tag
|
|
4. Update `CHANGELOG.md` with details about the fix
|
|
5. Tag a **new** release
|
