Extend `enum MergeTarget` to include a new variant, `Branch`.
The intended use of this new variant is to allow a `Patch` to have a
target branch other than the default branch.
The `Branch` variant holds a `TargetBranch` which, in turn, is ensured
to be a `Qualified` reference that begins with `refs/heads`, i.e. a
Git branch.
The value of `RAD_SOCKET` influences the outcome of `cargo test`.
Users that set this environment variable to, e.g. point `rad` at
a socket at a custom location, were surprised that execution of
tests would interact with their node.
Split `Home::socket` into two functions. `Home::socket_default` is
"pure" and only dependent on the path represented by `Home`. On the
other hand, `Home::socket_from_env` interprets the environment.
Most users will want to use `Home::socket_from_env`.
Configuration of database connections is not performed on `open`, which
leaves room for error (e.g. to miss specifying configuration).
Methods on `Profile` automatically supply the configuration of the
profile.
In testing code, just using the default configuration suffices.
Change the default value for the `synchronous` pragma from `FULL` to
`NORMAL`.
With this change, SQLite will not aggressively `fsync()` after every
transaction, so there is considerably less disk pressure as disk I/O
can be batched.
See <https://sqlite.org/pragma.html>:
> `WAL` mode is safe from corruption with `synchronous=NORMAL`, and

Also:

So, there is no risk of database corruption, and in the extreme
cases of sudden power loss or system crash, some transaction may
roll back.

Introduces the ability to explicitly block a peer via the node control
socket. Previously, the node only exposed follow and unfollow commands.
While the underlying policy database schema supported a Block variant,
there was no mechanism to trigger this state via the client handle.
The new block command:
1. Updates the node's follow policy to Block.
2. Immediately disconnects the peer if a session is active.
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.
Change `repositories_by_id` to return `impl Iterator<Item = Result<RepositoryInfo,
RepositoryError>>`
instead of `Result<Vec<RepositoryInfo>, RepositoryError>`.
This allows callers to handle failures on a per-repository basis rather
than having the
entire operation fail if a single repository lookup fails.
Previously, the method would stop processing and return an error as soon
as any repository failed to load. Now it processes all repositories and
returns individual results, making the API more resilient and giving
callers
more control over error handling.
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.
The `winpipe` crate which is our current best bet for support on Windows
requires that named pipes are at the magical location `\\.pipe\`.
Provide a default on Windows that matches this, and use our freshly
assigned IANA service name for it.
This is a breaking change, as we remove a `pub const`, it should be
reasonably easy to fix by dependents, and probably it was a mistake to
make the default `pub const` as dependents should call `Home::socket`
anyway.
