now that we have the swh graph compress CLI, we're moving away to using docker for automated compression, so this has become moot

• typing: minimal changes to make a no-op mypy run pass
• typing: convert leftover variable annotation to comments
• init.py: switch to documented way of extending path
• tox: add mypy environment
• requirements-test.txt: add back deps from master
• Makefile.local: sync typecheck target with global Makefile.python
• mypy: ignore psycopg2

• MANIFEST.in: ship py.typed

removing this form the review queue for now, as it will need py3.7 in the CI to pass tests anyway

Could you replace cast(GemspecMapping, MAPPINGS['GemspecMapping']) (and others) with an import of GemspecMapping from swh.indexer.metadata_dictionary.ruby?

• test_metadata typing: use type-specific mappings instead of cast

• CRAN lister: fix compute_package_url interpolation

• typing: minimal changes to make a no-op mypy run pass
• CRAN lister: make shelling out decoding compatible with Python 3.5
• mypy: add typing annotations for novel lister abstractions

I think the bulk of the task here is done. We can open another task if we notice any specific pain point later.

• swh identify -t snapshot: add support for symbolic refs
• test_cli.py: drop unused NoQA marker
• test_cli.py: fill in valid snapshot ID

Then I've dumped the branch list just before it's hashed (with P542 in swh.model.identifiers) and what I get is this:

alias HEAD 726566732f68656164732f6d6173746572
revision refs/heads/master 9768d0b576dbaaecd80abedad6dfd0d72f1476da
revision refs/remotes/origin/master c3c588713233609f5bbbb2d9e7f3fb4a660f3f72

where HEAD is an alias, but it's pointing to an object ID (this is on the sample git repo used for tests on swh-load-git, but I obtain similar results on any other repo I've tried).

What am I missing here?

That's not an object id, that's a branch name (refs/heads/master, in ASCII).

• test_cli.py: drop unused NoQA marker
• test_cli.py: fill in valid snapshot ID

• storage/db.py: drop unused format arg regconfig from query

doesn't actually pass mypy yet, will update
