Wire up the new `FetcherService`. This reduces the `Service` fetch
methods down to:
- `fetch`
- `fetched`
- `dequeue_fetches`
- `fetch_refs_at`
This simplifies the code by off-loading the logic to the `fetcher`
family of types, rather than handling the intricacies in the `Service`
itself.
The `Service` now just performs the necessary I/O based on the
returned events from the `fetcher`.
This also removes the fetching state from the node sessions. This
follows the single responsibility, and sessions now only care about
their connectivity.
Breaking changes:
- The `Connected` state of a peer no longer contains fetching
information, which was being returned as part of the JSON payload
result.
- The `rad debug` information for ongoing fetches contained the number
listeners awaiting for results, this was removed.
Be more defensive by preventing a node, that is not configured for
Tor, to not connect to `.onion` addresses via the `Service::connect`
method.
This means that an `Outbox::connect` should not be produced, and the
address table should not insert an entry.
When maintaining persistent connections, the config was consulted for
a peer address. Multiple addresses for a single `NodeId` can be
listed. This can result in a different address being used for
reconnecting if the `HashSet` returns in a different order.
The original address that was used for connection is in the `Session`,
so this should be used instead.
Evaluate the `error!` logging in `radicle-protocol`.
The majority of cases, the `error!` is downgraded to `warn!`. These
cases are generally useful to know if there's an issue, but the
operator cannon necessarily do anything about it.
In a few cases, `debug!` was chosen. These are generally when an error
means that a result is not part of an accumulation, or the system will
eventually correct itself during another event or restart.
If the previous message started with "Error", then the wording is
changed to say "Failed to".
Evaluate the `warn!` logging in `radicle-protocol`.
If the event is a result of something being suspicious in the running
of the protocol, then it remains a `warn!`.
However, if the system ends up ignoring the event and can continue
without issues, the log level is reduced to `debug!`.
There is an unfortunate lack of single-responsibility with handling the
addresses to connect to.
This is a band-aid fix until the point in time where this can better improved.
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}`.
The "seeds" command does only take a repository ID, and
carries the implicit assumption that the namespace with the same public
key as the Node ID of the receiving `radicle-node` process should be
used as reference for determining whether other nodes are in sync,
but no other namespace.
In the spirit of separating user and node identity, relax this, so that
the command also carries the public keys relative to which the sync
status should be computed. This allows to inspect sync status for
arbitrary namespaces via command.
For now, this feature is not exposed to the CLI, but `rad sync status`
always passes the public key of the active profile.
The "announce references" command does only take a repository ID, and
carries the implicit assumption that the namespace with the same public
key as the Node ID of the receiving `radicle-node` process should be
announced, but no other namespace.
In the spirit of separating user and node identity, relax this, so that
the command also carries the public keys for which the announcement
should be made. This allows to announce arbitrary namespaces out of
storage via command.
For now, this feature is not exposed to the CLI, but rather:
- `rad sync` always announce for the public key of the active profile.
- `git-remote-rad` ditto, as it calls the same codepath.
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.

It turns out that `sqlite::cursor::Row::read` is the panicky version of
`sqlite::cursor::Row::try_read` (which returns a `Result`).
While it is somewhat rare that SQLite reads fail, it is not unheard of.
In `radicle-cli` it might not be critical, but also `radicle-protocol`
and `radicle-fetch` are affected, and they could potentially panic a
`radicle-node` process.
Use `try_read` instead, and propagate down the error handling.
The logic for computing canonical references conflated the semantics of
annotated and lighweight tags, yielding confusing/wrong results. The
main culprit was the call to `peel_to_commit` in
`impl ReadRepository for Repository`, peeling tag objects away.
To resolve this, we separate out quroum computation per object type: one
implementation for commits, and one for tags.
Also move move canonical error types and methods into their own
module to have a cleaner file structure for the main logic.
Capture the `BTreeMap<Oid, u8>` type into a `Votes` struct, with its own API.
We were getting the objects from the repository twice – once in `Canonical::new`
and once again in `ensure_commit_or_tag` – so the latter was removed.
Use an `enum CanonicalObject` to specify which object types the canonical
process supports.
During `converges`, separate commits and tags, and ensure that we are only
looking at objects of one type. Note, that Fintan think this is actually the
*wrong* place to do it because we already filter the objects – so we should
keep track of that information higher up the callstack.

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.
