# Nix release process
|
|
|
|
## Release artifacts
|
|
|
|
The release process is intended to create the following for each
|
|
release:
|
|
|
|
* A Git tag
|
|
|
|
* Binary tarballs in https://releases.nixos.org/?prefix=nix/
|
|
|
|
* Docker images
|
|
|
|
* Closures in https://cache.nixos.org
|
|
|
|
* (Optionally) Updated `fallback-paths.nix` in Nixpkgs
|
|
|
|
* An updated manual on https://nixos.org/manual/nix/stable/
|
|
|
|
## Creating a new release from the `master` branch
|
|
|
|
* Make sure that the [Hydra `master` jobset](https://hydra.nixos.org/jobset/nix/master) succeeds.
|
|
|
|
* In a checkout of the Nix repo, make sure you're on `master` and run
|
|
`git pull`.
|
|
|
|
* Move the contents of `doc/manual/src/release-notes/rl-next.md`
|
|
(except the first line) to
|
|
`doc/manual/src/release-notes/rl-$VERSION.md` (where `$VERSION` is
|
|
the contents of `.version` *without* the patch level, e.g. `2.12`
|
|
rather than `2.12.0`).
|
|
|
|
* Add a header to `doc/manual/src/release-notes/rl-$VERSION.md` like
|
|
|
|
```
|
|
# Release 2.12 (2022-12-06)
|
|
```
|
|
|
|
* Proof-read / edit / rearrange the release notes. Breaking changes
|
|
and highlights should go to the top.
|
|
|
|
* Add a link to the release notes to `doc/manual/src/SUMMARY.md.in`
|
|
(*not* `SUMMARY.md`), e.g.
|
|
|
|
```
|
|
- [Release 2.12 (2022-12-06)](release-notes/rl-2.12.md)
|
|
```
|
|
|
|
* Run
|
|
|
|
```console
|
|
$ git checkout -b release-notes
|
|
$ git add doc/manual/src/release-notes/rl-$VERSION.md
|
|
$ git commit -a -m 'Release notes'
|
|
$ git push --set-upstream $REMOTE release-notes
|
|
```
|
|
|
|
* Create a PR for `release-notes`.
|
|
|
|
* Wait for the PR to be merged.
|
|
|
|
* Create a branch for the release:
|
|
|
|
```console
|
|
$ git checkout master
|
|
$ git pull
|
|
$ git checkout -b $VERSION-maintenance
|
|
```
|
|
|
|
* Mark the release as stable:
|
|
|
|
```console
|
|
$ git cherry-pick f673551e71942a52b6d7ae66af8b67140904a76a
|
|
```
|
|
|
|
This removes the link to `rl-next.md` from the manual and sets
|
|
`officialRelease = true` in `flake.nix`.
|
|
|
|
* Push the release branch:
|
|
|
|
```console
|
|
$ git push --set-upstream origin $VERSION-maintenance
|
|
```
|
|
|
|
* Create a jobset for the release branch on Hydra as follows:
|
|
|
|
* Go to the jobset of the previous release
|
|
(e.g. https://hydra.nixos.org/jobset/nix/maintenance-2.11).
|
|
|
|
* Select `Actions -> Clone this jobset`.
|
|
|
|
* Set identifier to `maintenance-$VERSION`.
|
|
|
|
* Set description to `$VERSION release branch`.
|
|
|
|
* Set flake URL to `github:NixOS/nix/$VERSION-maintenance`.
|
|
|
|
* Hit `Create jobset`.
|
|
|
|
* Wait for the new jobset to evaluate and build. If impatient, go to
|
|
the evaluation and select `Actions -> Bump builds to front of
|
|
queue`.
|
|
|
|
* When the jobset evaluation has succeeded building, take note of the
|
|
evaluation ID (e.g. `1780832` in
|
|
`https://hydra.nixos.org/eval/1780832`).
|
|
|
|
* Tag the release and upload the release artifacts to
|
|
[`releases.nixos.org`](https://releases.nixos.org/) and [Docker Hub](https://hub.docker.com/):
|
|
|
|
```console
|
|
$ IS_LATEST=1 ./maintainers/upload-release.pl <EVAL-ID>
|
|
```
|
|
|
|
Note: `IS_LATEST=1` causes the `latest-release` branch to be
|
|
force-updated. This is used by the `nixos.org` website to get the
|
|
[latest Nix manual](https://nixos.org/manual/nixpkgs/unstable/).
|
|
|
|
TODO: This script requires the right AWS credentials. Document.
|
|
|
|
TODO: This script currently requires a
|
|
`/home/eelco/Dev/nix-pristine` and
|
|
`/home/eelco/Dev/nixpkgs-pristine`.
|
|
|
|
TODO: trigger nixos.org netlify: https://docs.netlify.com/configure-builds/build-hooks/
|
|
* Prepare for the next point release by editing `.version` to
|
|
e.g.
|
|
|
|
```console
|
|
$ echo 2.12.1 > .version
|
|
$ git commit -a -m 'Bump version'
|
|
$ git push
|
|
```
|
|
|
|
Commit and push this to the maintenance branch.
|
|
|
|
* Bump the version of `master`:
|
|
|
|
```console
|
|
$ git checkout master
|
|
$ git pull
|
|
$ NEW_VERSION=2.13.0
|
|
$ echo -n $NEW_VERSION > .version
|
|
$ git checkout -b bump-$NEW_VERSION
|
|
$ git commit -a -m 'Bump version'
|
|
$ git push --set-upstream origin bump-$NEW_VERSION
|
|
```
|
|
|
|
Make a pull request and auto-merge it.
|
|
|
|
* Create a milestone for the next release, move all unresolved issues
|
|
from the previous milestone, and close the previous milestone. Set
|
|
the date for the next milestone 6 weeks from now.
|
|
|
|
* Create a backport label
|
|
|
|
* Post an [announcement on Discourse](https://discourse.nixos.org/c/announcements/8), including the contents of
|
|
`rl-$VERSION.md`.
|
|
|
|
## Creating a point release
|
|
|
|
* Wait for the desired evaluation of the maintenance jobset to finish
|
|
building.
|
|
|
|
* Run
|
|
|
|
```console
|
|
$ IS_LATEST=1 ./maintainers/upload-release.pl <EVAL-ID>
|
|
```
|
|
|
|
Omit `IS_LATEST=1` when creating a point release that is not on the
|
|
most recent stable branch. This prevents `nixos.org` to going back
|
|
to an older release.
|
|
|
|
* Bump the version number of the release branch as above (e.g. to
|
|
`2.12.2`).
|
|
|
|
## Recovering from mistakes
|
|
|
|
`upload-release.pl` should be idempotent. For instance a wrong `IS_LATEST` value can be fixed that way, by running the script on the actual latest release.
