* Use correct Poetry config when collecting Poetry projects
When collecting Poetry projects for caching, a '**/poetry.lock' glob is
used. However, in order to process the Poetry configuration, the
"poetry" command is run from the repo's root directory; this causes
Poetry to return an invalid configuration when there is a Poetry project
inside an inner directory.
Instead of running a single Poetry command, glob for the same pattern,
and run a Poetry command for every discovered project.
* Fix typo: saveSatetSpy -> saveStateSpy
* poetry: Support same virtualenv appearing in multiple projects
* Add nested Poetry projects test
* poetry: Set up environment for each project individually
* tests/cache-restore: Do not look for dependency files outside `data`
When the default dependency path is used for cache distributors, they
are looking for the dependency file in the project's root (including the
source code), which leads to tests taking a significant amount of time,
especially on Windows runners. We thus hit sporadic test failures.
Change the test cases such that dependency files are always searched for
inside of `__tests__/data`, ignoring the rest of the project.
* poetry: Simplify `virtualenvs.in-project` boolean check
* README: Explain that poetry might create multiple caches
* poetry: Run `poetry env use` only after cache is loaded
The virtualenv cache might contain invalid entries, such as virtualenvs
built in previous, buggy versions of this action. The `poetry env use`
command will recreate virtualenvs in case they are invalid, but it has
to be run only *after* the cache is loaded.
Refactor `CacheDistributor` a bit such that the validation (and possible
recreation) of virtualenvs happens only after the cache is loaded.
* poetry: Bump cache primary key
This option allows to specify if the action shall update environment variables (default) or not.
This allows to use the setup-python action in a composite action without side effect (except downloading/installing python if version is missing).
