# Backport Changes
|
|
|
|
Sometimes it is necessary to backport changes to the beta release of Clippy.
|
|
Backports in Clippy are rare and should be approved by the Clippy team. For
|
|
example, a backport is done, if a crucial ICE was fixed or a lint is broken to a
|
|
point, that it has to be disabled, before landing on stable.
|
|
|
|
Backports are done to the `beta` release of Clippy. Backports to stable Clippy
|
|
releases basically don't exist, since this would require a Rust point release,
|
|
which is almost never justifiable for a Clippy fix.
|
|
|
|
|
|
## Backport the changes
|
|
|
|
Backports are done on the beta branch of the Clippy repository.
|
|
|
|
```bash
|
|
# Assuming the current directory corresponds to the Clippy repository
|
|
$ git checkout beta
|
|
$ git checkout -b backport
|
|
$ git cherry-pick <SHA> # `<SHA>` is the commit hash of the commit, that should be backported
|
|
$ git push origin backport
|
|
```
|
|
|
|
After this, you can open a PR to the `beta` branch of the Clippy repository.
|
|
|
|
|
|
## Update Clippy in the Rust Repository
|
|
|
|
This step must be done, **after** the PR of the previous step was merged.
|
|
|
|
After the backport landed in the Clippy repository, also the Clippy version on
|
|
the Rust `beta` branch has to be updated.
|
|
|
|
```bash
|
|
# Assuming the current directory corresponds to the Rust repository
|
|
$ git checkout beta
|
|
$ git checkout -b clippy_backport
|
|
$ pushd src/tools/clippy
|
|
$ git fetch
|
|
$ git checkout beta
|
|
$ popd
|
|
$ git add src/tools/clippy
|
|
§ git commit -m "Update Clippy"
|
|
$ git push origin clippy_backport
|
|
```
|
|
|
|
After this you can open a PR to the `beta` branch of the Rust repository. In
|
|
this PR you should tag the Clippy team member, that agreed to the backport or
|
|
the `@rust-lang/clippy` team. Make sure to add `[beta]` to the title of the PR.
