Most of these changes should be self-explanatory.
* Atomic fetch was no longer used
* The default policy when initializing should be 'all', as it is with
`rad init`.
Dequeued fetches were always fetching all refs, instead of fetching the
specific refs that were initially requested. We fix that by storing the
refs to fetch in the fetch queue.
When using `network: "test"`, we shouldn't default to any public seed
node. This change makes sure that the "preferredSeeds" configuration var
is only given a value when `network` is `main`.
The previous change to the wire protocol introduced a bug: outbound
peers that failed to connect fully would not notify the service on
disconnect. This change fixes it.
* Make sure we cleanup pending peer states when disconnecting before
handshake.
* Make sure we don't panic if a peer disconnects before being fully
connected.
Introduce pinned repositories to the `profile::Config`, i.e.
`config.json`.
This is used for pinning repositories in the httpd `/projects` handle.
To allow returning all repositories, an `all` query parameter is also
included.
This is non-backwards compatible change, since we introduce the `show`
query parameter which, if not supplied, will default to `pinned`.

When a DNS error occured, the `dial` call failed and we didn't get a
connection attempt, just a disconnect. We fix that by always calling
back into the service when we attempt a connection.
There was an issue with the old version due to the use of `RawFd` as
peer IDs, since they are not unique for the lifetime of a process.
With this change, we use the new `ResourceId` type, though these are not
immediately available, as they are generated when the resource is
registered.
Allow some margin of error when sending multiple inventory announcements
at a time. Previously, they might end up with the same timestamp, so
only the first announcement would be processed by nodes. Now, we ensure
that the timestamp is updated.
To be able to use log setup across the different components of
heartwood, expose a `logger` module from `radicle`. This also includes
a `test` logger.
These modules are guarded behind a `logger` feature flag, so that
other crates are not bringing any uneeded dependencies.
This allows logging to be setup in `radicle-cli-test` so that when a
test fails, the log output is present for debugging purposes.

When a peer is performing a background and foreground fetch from two
different peers, the background fetch result was being used as the
result for the foreground fetch. This results in inconsistencies,
since the foreground peer has new updates from themselves.
The reason for this issue was the fetches that were queued were not
correctly being handled, and the other peer's results were being
returned instead.
This fixes the queueing and dequeueing by ensuring that the queued
fetch occurs, passing the correct result channel. This fetch will then
be subsequently dequeued correctly and the foreground fetch obtains
the correct result.

This test is flakey and requires further investigation. Some extra
assertions are added to ensure that the expected behaviour is
happening upon fetching. It is unknown if the fetch queue is behaving
properly, and it's suspected that some existing fetch results might be
used for queued fetches.

Previously, we might ban a node if we're having trouble connecting to
it, but this could be due to internet connectivity issues.
We introduce a penalty score for nodes, that increases if there are
connection issues or the node misbehaves, and decreases on successful
connections.
When connected to new nodes, we sort them so that low-penalty nodes are
attempted first.
Some test flakes would occur due to the `converge` function looping
forever. It was noticed that in these cases the log output would look
like:
test: Node z6MkqTKLVnFdVF24PQiDoQffbTPT7U5igghS3XWuFJLfah1P has
{(Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),
PublicKey(z6MkemMxfWhRQFKy4UPX7FsN8GjLAZ9T65rbmDsUn7fchioP)),
(Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),

(Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),
PublicKey(z6MkqTKLVnFdVF24PQiDoQffbTPT7U5igghS3XWuFJLfah1P))}
with further investigation, the variable `all_routes` was found to be
smaller than the calculated routes.
Instead of checking `==`, instead check that
`routes.is_superset(&all_routes)`, which means that `routes` must be
equal to `all_routes`, but allows it have extra entries.

Since node announcements are stored and retrieved from disk (due to the
PoW), the timestamp on it is never updated. This means it can be too old
to cache and not sent/received by nodes. Fix this by having a max age.
Instead of creating the DB policies handle when needed, construct the
handle when the `Worker` pool is being constructed.
This replaces the usage of the DB handle with the `Worker`'s field
instead.

If a node had removed a seeding policy and another node fetched from
it, then it would perform the fetch.
Instead, check the policy during the authorization step and prevent
the fetch is the resulting policy is `Block`.
Note that the policy will be `Block` iff the `Block` policy was
specifically set or the `Block` is the default policy for the node.

Nix Flakes[[0]] are a more modular way of expressing nix derivations.
The `flake.nix` file describes:
- How to build the project, or components of a projet, via `nix build`
- What "checks" can run for a project, which can be executed via
`nix flake check`
- What binaries can be run, e.g. `nix run .#rad` to execute the CLI
This approach is preferable since a lot of the Nix ecosystem is using
Flakes -- despite it still being marked as experimental.
One interesting benefit, that needs confirming, is that a check can be
run from a remote Git source. So if someone creates a patch on
Radicle, someone else with the `nix` binary can execute:
nix flake check git+https://app.radicle.xyz/nodes/seed.radicle.xyz/rad:z3gqcJUoA1n9HaHKufZs5FCSGazv5?refs=patches/<patch id>
This means that anyone with `nix` can check patches without having to
fetch the patch itself.
Another obvious benefit will be that it allows the Radicle binaries to
enter the Nix ecosystem.
The big caveat to both of the above is that, currently, the tests are
failing while running `nix flake check`. They are currently disabled
with `doCheck = false`. They are potentially failing due to some
strange sandboxing issues which are being looked into.

Since forking creates your `rad/sigrefs`, which then needs to be backed
up forever, we avoid forking on `rad clone`. This should make little or
no difference for users, as the "fork" will be created on `git push`.
If a delegate is missing the default branch for a project certain
computations will fail, e.g. getting the canonical mainline branch.
One prevention for corrupting data is refusing to fetch a delegate
that does not have the default branch, when the repository is a
project. It is assumed that the repository is not a project if calling
`Doc::project` returns an error, since the error variants are not
found and parsing errors.
This is only checked in the case of a delegate since non-delegates are
safe to created COBs that don't require the default branch,
e.g. creating an issue.
Instead of having a routing database, and an addresses database,
consolidate that in a single database called `node.db`.
We also simplify database access, by providing a single type for opening
the database, and use traits to access the various functions.
We create a new `seed::Store` that has seed-related methods split out of
the `address::Store`.
Note that tracking is still in its own database currently, as it isn't
ephemeral state. This makes it easy to delete the new `node.db` without
risk of losing any important information.
To avoid renaming all database methods, we create a `Stores` wrapper
that allows us to access routing, addresses, seeds etc. without type
ambiguity.
This is a breaking change and requires `addresses.db` and `routing.db`
to be deleted.
Currently, if refs are updated while the node is stopped, these refs are
not immediately announced when the node starts, due to the node being
unaware of the updates.
To remedy this, on startup, we compare the refs we have in storage with
the refs we announced to the network. Since only our own refs could have
changed while the node was stopped, this change only applies to owned
refs. If we detect that storage has changed while the node was stopped,
we create ref announcements for the updated repos and store them in our
gossip database. These announcements will be included with other
historical gossip announcements when nodes connect to us.
To keep track of what was announced, we store our local node's sync
status in the database. This is also useful when using the `rad sync status`
command, as it tells us what oid our local node is at, and whether it
is aware of our local changes yet.
In addition to this, we make a small fix: previously, inventory and ref
announcements originating from our local node were not stored in the
announcement database. We ensure that they are via the new `announce`
method.
This command shows the sync status of a repository by consulting the
database via the node.
To make it work, we call into the address store to update the
`repo-sync-status` table when receiving ref announcements that are
relevant to us.
An informational message for the protocol is useful for sending
messages to a node that is not required to be relayed.
This message is introduced by starting with an ACK message for a set
of references being synced. This fixes an issue for announcing to a
node that is already synced, since it can now ACK that it received the
message and replies that it is synced.

It can be useful to return the `RefsAt` that was announced for this
node, for example, to compare it to node events.
Change the `Handle` method to return `RefsAt` so that when it is
called it returns the local node's `RefsAt`.

The previous system allowed the same RID to be fetched from multiple
nodes concurrently, which caused issues, especially when cloning.
Worker code assumes that there is only one fetch per repository going on
at any given time. This change ensures that.
We keep a global fetch queue, instead of having a queue per session. We
also enqueue fetches if a session is at capacity. Finally, we allow
multiple fetch requests to receive results for the same fetch.
