Leverage `schemars` to generate a JSON Schema from our structs for
configurations and those occurring within them.
The output of `rad config schema` can be used by editors to provide a
smoother editing experience for the configuration file. Discovery
attributes (both keys and values) is greatly improved with the schema
helping in the background.

The motivation of this change is to move away from tying signing to be
specifically for ed25519. The reason being that the protocol will want move
towards two different kinds of signing – the node signing artifacts, and an
author signing artifacts.
This change captures the former, node signing, by introducing a `Device` type
that is the `NodeId` – a PublicKey underneath the hood – and a signing
mechanism. This allows the replacement of the `Signer` trait being used – which
always assumed a `PublicKey`. Instead, the `Device` is constructed with
`NodeId`.
In `radicle-cob`, a signer is expected to implement
`signature::Signer<ExtendedSignature>`, and everywhere in `radicle`,
`radicle-node`, `radicle-cli`, and `radicle-remote-helper` is expected the
signer is expected to implement `signature::Signer<Signature>`.
A `Device` implements both of these but only requires
`signature::Signer<Signature>` to do so – since an `ExtendedSignature` is
essentially `(PublicKey, Signature)`, and the `NodeId` of the `Device` can be
used.
This change introduces versioning to the identity document format.
The `Version` type is introduced to capture this. Importantly, it is very
restricted in its construction and API. `Version::new` provides a smart
constructor to ensure that it is only ever constructed within the expected
bounds of `0 < v <= IDENTITY_VERSION`, where `IDENTITY_VERSION` is the constant
for the current version.
Note that serializing of the `Doc::version` is skipped to preserve the `Oid`
outputs of all the tests – which means that the first `version` is always
implicit and is not really expected to exist in the serialized forms of the
identity document.
The aim of this change is to make the `Doc` type more safe to use by approaching
the design via [Parse don't validate][[0]] approach.
The problem with the previous approach was that all field were `pub` and thus a
`Doc<Verified>` could easily be mutated and serialized. Granted, the code that
used the serialization would tend to verify the `Doc` first, however, this
approach *ensures* that only a verified `Doc` can be serialized. It also meant
that trying to add new data that would follow the parse approach would require
more generic parameters on top of the existing `PhantomData` parameter, i.e. we
need to do something like: `Doc<RawField, V> -> Doc<ValidField, V>`.
The new approach splits the type into two separate types: `RawDoc` and `Doc`.
The former is allowed to be mutated at will, and uses types that are less
strict. The latter is the valid type that can only be constructed by validating
a `RawDoc` (or the `initial` constructor). The `Doc` type's fields can then only
be accessed by read-only methods.
Solves the problems above by only allowing mutations to `RawDoc`, as well as,
new fields being added to `RawDoc` which are then validated via
`RawDoc::verified`.

Allow unknown fields to pass through when deserializing the `Project` payload.
This allows the deserialization to be more resilient when unknown fields are
added, e.g. from the CLI, and improves backwards-compatability when new fields
may be added in the future.

The command now works with both a replica target *and* a seeds target.
This is especially useful to eg. ensure that a preferred seed has been
synced, while still trying to hit a higher replica count.
The fetch V2 improvements introduced a `UserInfo` type that is used to
set the Git config's name and email when cloning a repository. This
`UserInfo` can also be used when creating a new `Repository`.
The `Storage` type now takes a `UserInfo` so that it can be passed to
`Repository::create`, for creating a new repository.
For testing, this requires adding a new `fixtures::user` so that
testing `Storage` instances can be easily constructed.
It also means that the `radicle-cli` tests all changed with new SHAs
since the name and email are used as part of the hashing input.
N.b. the order of the timelines while testing the identity cob
changed. It's not clear why that is.

Introduces a new COB type to store repository identity documents.
The reason for this change is to:
1. Simplify the code, as the identity document logic resembled a COB,
yet it had custom logic. This allows existing COB code to be used for
identities.
2. Make identity document update logic more flexible, since COB actions
can be added in the future.
3. Re-purpose existing tools around COBs to work on identities, eg. `rad
cob`.
4. Unify the concept of an identity change proposal, with regular identity
changes. This means we can remove the `id.proposal` COB in favor of
using the `id` COB itself.
Notes
-----
* Each repository has one Identity COB.
* The `Proposal` COB has been repurposed into the `Identity` COB.
* Identity documents are stored as *embeds* inside the Identity COB
actions.
* The action that contains new document versions is called `revision`,
just like the Patches COB.
* The namespaced `rad/id` ref is a symbolic reference to that Identity
COB.
* The canonical `rad/id` ref is a direct reference to the commit in the
Identity COB that contains the latest *accepted* revision of the
document.
* All commands for managing identities have been folded into `rad id`.
Hence `rad delegate` and `rad edit` are removed.
* The concept of "rebasing" an identity document is gone.
* The `rad id` output has been updated to match the style of other
commands.
* When a revision has enough signatures, it is automatically adopted as
the current identity, there is no longer the need for a "commit"
action.
* When an identity revision is proposed, and the current identity has a
threshold of `1`, that identity is automatically accepted due to the
above point.
* The idea of "verifying a peer's identity branch" no longer applies, as
COBs cannot be verified one history at a time.
* Since the root commit of the Identity COB does not have a "Resource"
to point to (it would have to point to itself, which is impossible),
we've made the resource id optional for COBs.
Private repos are implemented by extending the identity document with a
`visibility` attribute, that can either be `"public"` (default) or
`"private"`.
In case of `private` visibility, only the delegates are allowed to view
the repo, as well as any DIDs added to the allow list.
To implement repo visibility, we simply block fetches from and
announcements to peers for whom the repo should remain invisible.
Private repos are also not announced in the `inventory` message, since
the full list of peers that *may* have the repo is retrievable from the
repo identity. This could cause errors if eg. a peer who is allowed to
view the repo doesn't actually have it. However this is an ok trade-off
for now to keep the complexity low. For repos to truly be private, it's
important that the RIDs don't leak either.
Finally, we modify `radicle-httpd` for now to only list public repos.
Eventually, we would want to change this depending on whether an allowed
peer is authenticated with the service or not.
---
It's also worth mentioning why this approach was taken, vs. end-to-end
encryption. The reasons are as follows:
1. Nodes that do not have access to a private repo will generally not want to
replicate encrypted data that they cannot examine or use.
2. The chosen solution is trivial, while encrypting git objects isn't.
3. Performance of the chosen solution is much better, there is no
overhead.
4. Privacy of the chosen solution is better: RIDs are never leaked, and
neither is the existence of a private repo, nor who has access to it.
There is one downside: Paying for storage of private repos is no better
in terms of privacy than what GitHub offers. Hosting providers will have
access to your private repos, if this solution is used.
> I'm going to be making a set of breaking changes to COBs in order to
stabilize the data formats. This is hopefully a one-time change that
bundles various breaking changes.
All COBs have been reworked: issue, patch, id.
The changes included are:
* Revise the assign and tag actions to take a single list of
assignees/tags to set, instead of an "add" and a "remove" list. This
makes API usage simpler when editing issues, and simplifies the apply
function
* Rename "tags" to "labels", and the tag action to label. This is
because tag is confusing in the context of git, as it could mean a git
tag. Using label removes that confusion.
* Use DIDs instead of PublicKeys for assignees -- this is more
future-proof
* Modify the manifest file format in the COB tree. Mainly, remove the
`history_type` key which is redundant, and use camelCase for keys
* Flatten the `Thread` actions into the parent action type
* Ensure that operations on redacted objects do not fail, since
redactions could have happened concurrently
* Use a consistent naming scheme for actions, using `.` as separator
* Consolidate comment types and remove `CodeComment`, by adding an
optional `location` field to `Comment`
* Add many placeholder actions that are not yet implemented
To preserve backwards compatibility, a `legacy` module is created with
the old `apply` function. When loading the manifest, we check whether it
is a legacy COB or a "stable" COB, and in the legacy case, use the
legacy code to materialize the state and then convert the object into
the stable type. Eventually, we'll delete the legacy code.
This change updates to the latest radicle-git-ext, which required a
few changes within the radicle family of crates.
One set of changes is that the radicle-git-ext crate subsumes
git-commit, git-trailers, and git-ref-format -- so all those imports
go through radicle-git-ext.
The commit code requires that parent `Oid`s point to commits, which
made some tests fail. One of the reasons for these failures is that
the patch tests used fabricated `Oid`s and so the verification would
fail. This is fixed by allowing the test context code to create
`PatchRequest`s that create valid commits.
The other reason for failure was that the identity `Action` passed an
`Oid` that pointed to a blob. This is fixed by removing that code and
making a note of it in documentation.
The final major change was moving the Refspec type into git-ref-format
and removing the AsRefspecs trait. The trait was not required and
could its usage could be replaced by simpler code.

When a merge is applied to a patch, we check whether the threshold
of delegates has been reached, at which point we set the patch status
to `merged`.
This requires threading the identity document oid through the "apply"
process.
Introduce a canonical reference for refs/rad/id to aid in discovering
information about a repository without knowing a peer -- e.g. if a
peer wants to clone a new repository it needs to find out which peers
are delegates for that project, but does not know what their NIDs are
up front.
The approach mirrors the canonical `head` for a repository and
introduces useful constructors for `Doc`/`DocAt`.

Improvements to the CLI output as well as converging towards
`termion` as a backend.
The crates we were using for prompting and spinners were based on
a terminal backend called `console`, which is not really used
anywhere else. There were also limitations in terms of the output
of these crates.
Therefore, we switched to the `inquire` crate for prompting, using
the `termion` backend, which is very standard.
Additionally, we simplify the terminal output to use symbols:
! for Warning
✓ for Success
✗ for Error
... Instead of a mix of words and symbols.
We also include a modified version of the `yansi` crate which plays
well with our table formatting functions by automatically truncating
and padding output in a unicode-aware way.
The olpc-json crate's CanonicalFormatter does not escape certain
control characters, including new lines. This means that when a COB
gets serialized that includes new lines, those new lines are
serialized verbatim. Upon deserialization `serde_json` -- and any
other JSON deserializer -- will fail due to the encounter of these
control characters.
This behaviour was prevented in radicle-link with the definition of
its own CanoncialFormatter that encodes the control characters
correctly.
Inline this definition of the formatter, under MIT license, to ensure
the correct and remove oplc-cjson.
The behaviour is checked using a multiline test in the issue COB.

The signatures for Radicle identities were using the documents
content.
It is standard to use the hash of the content instead, since signing
and verification is faster on a smaller set of data.

signing and verifying payload.

The `validate` method of `Project` was unused, which is problematic if
the attributes are supposed to be validated based on some
constraints. The issue is that `Project` provided public construction
of its fields with enforcing validation.
This change makes `Project`'s attributes private and introduces a
smart constructor `new` which is fallible if any of the constraints
are not met. The error type was changed to be a vector of errors since
all of these errors can be collected for better error reporting.
Deserialization also provided a way of constructing a `Project`
without ensuring any of the constraints were checked. To prevent this
a hand-rolled `Deserialize` is provided that goes through
`Project::new`.
To access the fields of `Project`, accessor functions are added and
all call sites are updated to use them.
