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.
When piping the output in for eg. `head -n 1`, the `head` utility
might close down the pipe at some point, yielding a broken pipe error.
We catch that and simply return if that's the case.
Adds the new `migrate` sub-command to migrate the COB database.
Checks for version when opening the COBs database and suggests the
command on out of date version.
Also adds the 2nd migration to the COBs cache, which updates the patch
JSON schema.
Previously, COB change commits would not distinguish between their
parents. This means that they would try to load source code commits
(eg. for patch COBs) and then fail since those commits wouldn't have a
manifest or `Rad-Resource`.
We introduce a backwards compatible change here which is that parent
oids that are not COB commits are accompanied by a commit trailer called
`Rad-Related`. This is for all related content that should be pulled in
but is not part of the change graph proper.
When building the change graph, we simply ignore commits that are marked
as "related".
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.
