Allowed passing keyword arguments to subprocesses
Changes
This PR makes it possible to pass keyword arguments to Popen, through run_process, open_process or to_process.run_sync. In the later case, a new subprocess is always created, since it wouldn't be possible to reuse a worker process created with different keyword arguments.
Checklist
If this is a user-facing code change, like a bugfix or a new feature, please ensure that you've fulfilled the following conditions (where applicable):
- [x] You've added tests (in
tests/) added which would fail without your patch - [x] You've updated the documentation (in
docs/, in case of behavior changes or new features) - [x] You've added a new changelog entry (in
docs/versionhistory.rst).
If this is a trivial change, like a typo fix or a code reformatting, then you can ignore these instructions.
Updating the changelog
If there are no entries after the last release, use **UNRELEASED** as the version.
If, say, your patch fixes issue #123, the entry should look like this:
- Fix big bad boo-boo in task groups
(`#123 <https://github.com/agronholm/anyio/issues/123>`_; PR by @yourgithubaccount)
If there's no issue linked, just link to your pull request instead by updating the changelog after you've created the PR.
I am wondering if we need something slightly different to also accommodate #605. Separate process pools with different options?
That would be nice indeed.
