Introduce the `radicle-core` crate for housing data types that are at
the core of the Radicle protocol. The initial data type being added is
`RepoId`. To make the crate as lightweight as possible many of
dependencies are optional and gated by feature flags.
The crate is marked as `no_std` even though it unconditionally depends
on `radicle-crypto`, which is *not* `no_std`. This is to invite
refactoring of `radicle-crypto` to `no_std` at a later time.
The `localtime` crate was defined by cloudhead, and is a minimal
repository with a single `lib.rs`.
Instead of using it as an external dependency, copy the code directly
into a new workspace crate `radicle-localtime`.
The default `serde` implementation goes through the `LocalTime`'s
seconds values rather than milliseconds, since this is the more common
format. This allows the removal of the `serde_ext` functions.
The one place milliseconds was used was for the
`radicle::cob::common::Timestamp` type, where the `Serialize` and
`Deserialize` implementations are manually written.
It also adds a `schemars` feature to remove `schemars_ext` functions
in `radicle` as well.
Implement `IntoIterator` for the `BoundedVec`.
This allows the use of `into_iter` for returning the owned data,
rather than references via the `Deref` implementation.
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.
Previously, the `RepoId` was backed by the `git2::Oid` type, which has a `Hash`
implementation that uses `std:#️⃣:Hasher::hash`. This uses a length prefixed
form for hashing.
When switching to `radicle_oid::Oid` and implementing `Hash` without the length
prefix, this subtly changed the hashes going forward.
These hashes are used in `BloomFilter`, which is the type underlying `Filter`.
This resulted in cases where a previous `Filter` that certainly contained
`rad:z3gqcJUoA1n9HaHKufZs5FCSGazv5` were suddenly reporting that they did not
contain this repository.
Changing the implementation of `Hash` for `radicle_oid::Oid` fixes this, and is
confirmed by adding the regression test in `filter.rs`.
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.
In many tests we assert that encoding and decoding gives the same
object. Let's call that a "roundrip", and also provide a proc macro to
generate such tests.
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.
I was greeted by `rad patch redact` with
called `Result::unwrap()` on an `Err` value:
Error { code: None, message: Some("failed to convert") }

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.
Remove `fn deserialize` and instead provide a trait `fn decode_exact`
for testing.
Refactor errors, so that we can now cleanly distinguish between
`Error::UnexpectedEnd` which means that decoding might work given
more data, and `Error::Invalid`, which means that no amount of
additional data will decode.
While at it, cleanup the variants of `Error::Invalid`, and provide `ControlType`.
What made the issue fixed in the parent commit harder to spot
for me was the multitude of concepts and terms involved in
encoding: What's *serializing* vs. *encoding*? Why is there
this odd `Frame::to_bytes`?
So I decided to clean up a bit. I removed `fn serialize` so that the
logic stays close to the data, and instead of it provide
`fn encode_vec` in `trait Encode` so that we don't add up with
one-offs like `Frame::to_bytes` again.
Also we make use of `encode_vec` in the tests.
In 3c5668edd2 I mistakenly moved the check
the length of an encoded `wire::Message` from its `impl wire::Encode` to
the `fn serialize`, so that it would not apply only to messages (as
originally intended), but to *any* argument of `serialize`.
This is not a problem for gossip messages, but catastrophic for Git
streams, which tend to send a lot of data.
The fix is simple: Move the check back into `impl Encode for Message`.
The upgrade of the `radicle-crypto` crate was missed when upgrading
semver versions.
Unfortunately, since it is at the base of the dependency tree, all
crates that depend on it require an additional upgrade.
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.

Pay more attention to when a Node ID is displayed in compact form. As
this was sometimes used to save space, e.g. in `rad node status` in
combination with long node addresses (like .onion names), also implement
a compact format for node addresses and use that instead in some cases.
Progress notifications in spinners keep the short form.
The `[T]` and `[I]` are interpretted as links when running `cargo doc`. This
table is surrounded in a code fence to prevent this, but also provide a better
view of the table when rendered to HTML.
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.
