Make `git2` an *optional* dependency of `radicle-cob`, and refactor
`radicle` to depend on crates that in turn do not depend on `git2`
*non-optionally*
The main offending dependency of `radicle-cob` is `radicle-git-ext`
from the `radicle-git` workspace in repository
(rad:z6cFWeWpnZNHh9rUW8phgA3b5yGt) which *non-optionally* depends on
`git2`.
So, to achieve removal of this dependency:
1. The crate is refactored to depend on the new crates
`radicle-git-ref-format` `radicle-git-metadata`, and
`radicle-oid` introduced in the previous commits, instead of
`radicle-git-ext`.
2. Some code from the `radicle-git-ext` crate in the `radicle-git`
workspace in repository (rad:z6cFWeWpnZNHh9rUW8phgA3b5yGt) is
copied. See `crates/radicle-cob/src/backend/git/commit.rs`.
This cascades to `radicle` and its dependents.
Firstly, the there is an
`impl Deref<Target=git2::Oid> for radicle_git_ext::Oid`. This made
it very convenient to just deref to obtain the wrapped `git2::Oid`,
so there are many expressions of the shape `*oid` in `radicle` and
its dependents. However `radicle-oid` does not provide
`impl Deref<Target=git2::Oid> for radicle_oid::Oid`, as notably,
`Target` is an associated type, and not a type parameter, so an
implementation of `Deref` would tie the new `Oid` too tightly to a
particular implementation.
Instead, work with `impl From<radicle_oid::Oid> for git2::Oid`
(which can be enabled using the feature flag `radicle-oid/git2`).
This explains the changes from `*oid` to `oid.into()` at every
transition to "`git2` land".
Secondly, `radicle` and its dependents are refactored to also depend
on `radicle-git-ref-format` and (much less prominently)
`radicle-git-metadata` instead of `radicle-git-ext`
This is to avoid pulling in `git2` via these dependencies.
Thirdly, as the re-exports in `crates/radicle/src/git.rs` change,
they are at the same time also cleaned up. Notably, the types from
`radicle-git-ref-format` are re-exported under `fmt` only, not "twice".
While overall this obviously is very much a breaking change, these
changes should mostly amount to changing from `Deref` to `Into`, i.e.,
`*oid` → `oid.into()` and rewriting imports for `radicle::fmt`.
This is indicated by the mostly mechanical nature of the changes to
`crates/radicle-{cli,node,remote-helper}`.
Whenever the node fetches new updates, it checks if canonical references can be
updated. The node has learned how to return these results and emit them as node
events. This is a breaking change since it adds a new variant the `Event` type,
which is not forwards-compatible.
Mostly changes of `use`s and moving components to `radicle-protocol`,
with the goal of just getting `radicle-node` to work on top of the new
`radicle-protocol` crate.
