T843: Vault: Add a "git bare" tarball cooker
Summary

It can cook directories (by adding a synthetic revision pointing to it)
and revisions.

Current limitations:

  • It does not deduplicate directories and files at all, and queries all objects one by one.
  • No support for missing/absent contents
  • No support for missing submodules

Tests reuse existing tests of the DirectoryCooker and
RevisionGitfastCooker using parametrized pytest fixtures.

As said on IRC, I don't think this 'directory' support should be in there. If it's only purpose is to help reusing tests, then tests should be refactored instead of adding code in the business logic.

111

Maybe we should not use an hardcoded 'mater' branch here? we should at least make it configurable (nowadays)?

134

why in "append" mode ?

179

do you mean objects like SkippedContent?

It's also useful when testing manually with the CLI.

111

We can make it configurable when we'll need it.

179

"filtered" is the generic name for "skipped or hidden or missing"

don't use append mode for writing objects

I don't really understand why (what is really the added value of this git-bare-directory' cooker), but do as you wish.

179

indeed
