Bun v1.2 now uses the text-based `bun.lock` as its default lockfile format. Adjusted the action-cache examples to reference and cache `bun.lock` instead of the previous binary format.
In Clojure, Lein tool is used to generate template for various projects.
Lein project metadata (including project dependencies) are stored in
prject.clj (in root directory) file. Lein downloads dependencies in
classpath (~/.m2/repository). So here I am caching ~/.m2/repository path
for reusing cache in subsequent builds.
The default `STACK_ROOT` is `~/.stack` only on Unix-like operating systems. On Windows, the default is `%APPDATA%/stack` (usually `%HOME%\AppData\Roaming\stack`).
On Unix-like OSs, Stack stores GHC and other tools in a `programs` directory in the `STACK_ROOT`. On Windows, Stack stores those tools and MSYS2 in `%LOCALAPPDATA%\Programs\stack` (usually `%HOME%\AppData\Local\Programs\stack`).
* Fix bugs in example of how to use with pipenv
The current example of how to use `@actions/cache` with pipenv has two
problems:
1. The cached virtualenv that pipenv creates has `bin/python` as a symlink
into paths like `/opt/hostedtoolcache/Python/3.7.11` that explicitly
include the patch version of python. When the cache is restored onto a
machine running a slightly different version of python, e.g., when
GitHub upgrades its runners from python 3.7.10 to 3.7.11, then any
attempt to run python in the workflow mysteriously fails with errors
like `Failed to load paths: /bin/sh: 1: /home/runner/.local/share/virtualenvs/myrepo-sOIMCiTO/bin/python: not found`.
Therefore the patch version of python should be included in the cache
key.
2. `pipenv --install` has the unfortunate behaviour of not cleaning out
any pre-existing packages. That is, if the `Pipfile` first contains
dependencies on `foo` and `bar`, and then you remove `bar` from the
`Pipfile` and run `pipenv install` again, `bar` is still included in
the virtualenv.
This can cause false-positive test failures: when a dependency is
removed from the `Pipfile` but there is still code that relies on the
removed dependency, tests can still pass if the dependency comes from
the cache based on a previous revision of `Pipfile.lock`.
Therefore `restore-keys` should not be set.
This PR attempts to address both of these issues.
