Instead of having two types, we simply have one, called `Entry`, which
we rename from `Change`.
There was no real benefit to having two almost identical types, but lots
of added complexity. This patch simplifies the crate by removing one of
the types.
It turns out that the CRDT formed by the union of Git DAGs
is enough to guarantee everything we need for COBs.
This changes the following things:
* COB operations no longer need to be commutative
* COB histories are traversed in the same deterministic order on all
replicas
* It's now possible to implement RSMs on top of COBs, eg. scripting
* Lamport clocks have been removed
* `radicle-crdt` is no longer a dependency of `radicle`
* COBs are no longer instances of `Semilattice`
* The `Ops` type was removed in favor of having `Op` contain multiple
actions
This is a fairly substantial change, which adds a new configuration file
to the user's `$RAD_HOME` that includes node configuration, including
the alias, and also makes node aliases required.
When running `rad auth`, the user is now prompted for an alias, which
defaults to `$USER`.
When running `rad self`, the alias is now shown.
If the user runs radicle without a config file, the defaults are loaded,
and `$USER` is used as the alias.
Remove most of the user-friendly functionality and simplify this command
so that it is only used for scripting.
`git push rad` is now the proper way of updating patches.
Remove this command in favor of the `git push` flow.
We also remove the `rad/patches` remote configuration which wasn't
working properly with `git fetch --all`.
Help the user when creating a patch by listing the messages of all
commits associated with the patch in almost the same format as git uses
for squashing.
This adds a simple `validate` function to COBs that is run on load. It
allows COBs to check whether they are valid, once all operations are
loaded, and return an error if not.
We change `Patch::latest` to always return something, because a patch is
malformed if it doesn't have at least one revision, and thus would not
load in the first place.
This also implies that there is a latest revision in the face of
concurrent updates.
Note that currently, traversal order for concurrent updates is still random.
This will be fixed in another patch.
Move `merges` from `Revision` to `Patch`, and key them by actor.
This ensures that only one merge is possible per actor. We also make
sure that only one revision can be merged at a time, and signal a
conflict if more than one revision is considered merged.
Finally, we make sure that merges have the same target-branch commit
to be considered equal.
This adds the ability to the git-remote-helper to open and update
patches via a `git push` to the magic ref `refs/patches` and
`refs/heads/patches/<patch-id>`.
The main change is that we had to move away from offering the `connect`
capability in the remote helper, to offering `push` and `fetch`
individually.
To get a feel for how this works, see the `rad-patch-via-push.md`
example.
Now logic for parsing and supporting user facing Patch messages is
shared for creation and editing, refactor and move supporting code to
terminal::patch.
This fixes a bug where the title may be incorrectly parsed, resulting in
it containing multiple lines.
Trying to open or update Patch will fail if the user's working copy is
out of sync with the Radicle projects canonical head.
Fix this by always operating on the storage when opening or
updating a patch.
It wasn't being set correctly, and it's not the place for it,
so we remove it and set it in `httpd`.
Note that `Remote` is now simply a wrapper around `SignedRefs`.
If we want to remove the type or turn it into an alias, it will
require touching lots of different parts of the codebase. I opted
not to do that here as it's lower priority.
Instead of `Node::announce_refs`, we call `rad sync` to have the
terminal block while waiting for nodes to fetch the changes.
We also change the use of `git push` in the patch command to not
trigger syncing in that case.
