Shows you updates on local repositories.
Included here is a basic implementation of a notification system. A new
database is created and updated after every fetch, with refs that have
changed.
The `rad inbox` command can then list items in the database and delete
them.
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`.
Instead of using tuples and lots of arrays, this commit tries to use
`BTreeMap`s to provide more context to review, issues, patch and other
comments.
Also the returned object by the httpd is more aligned with what is
needed by the consumer, so less recomputation is needed for display.
When evaluating a COB, expose to the `apply` function the operations
concurrent to the current one being applied. These are essentially
"related" nodes in the graph, that are neither ancestors or descendants.
This will let us for example have different failure modes depending on
whether there were conflicting operations, as well as expose conflicts
to the user.
Instead of having a timeline of a patch be global and sorted by
timestamp, organise it via revisions. Each revision has an entry in
the timeline, sorted by timestamp. Under each revision, a series of
updates are inlined, also sorted by their timestamps. Currently, these
updates can either be reviews or merges.
For example:

To make `CodeLocation` reusable across different components, require
that a commit's `Oid` is part of the struct.
An `Oid` is necessary since the `path` can refer to a path at any
point in time throughout the history of the repository. By pinning the
commit that is being referred to, the path will refer to the path
within the associated tree [of the commit].

`Infallible` is a more appropriate type in comparsion to `()` for
comments that do not require a `CodeLocation`.
That is because if the type for `location` is `Option<()>`, this means
that `Some(())` can be constructed, however, we never intend to
construct that variant. On the other hand, `Infallible` can never be
constructed, and so, only `None` can be used.
This requires updates to some functions to use the generic `T` and
also handle the different kinds of `Comment`s -- `Infallible` and
`CodeLocation`.

This allows the display of any edits done to comments,
replies and issue descriptions.
This commit doesn't remove the body property
which is the latest comment body but adds a edits property.
Also adds an author property to the `Edit` struct,
which allows us to see the author of an edit action.
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.
The `Patch` API and semantics are changed a little bit:
* It's now valid again to propose a revision without being the patch
author.
* To get revisions by the patch author, `Patch::updates` is used.
* `Patch::latest` now only looks at revisions by the patch author.
* Added `Patch::revisions_by`, `Patch::authors` and `Patch::latest_by`.
* The merge behavior on git-push is improved to favor revisions that
merge more recent commits. We also allow for merging the non-latest
revision.
Instead of returning histories from `radicle-cob`, we return an
evaluated object which we build during initial graph traversal.
We do this so that branches can be correctly pruned when operations are
invalid at the application level. This way, new operations are not
building on top of invalid ones contained in the history.
To achieve this, we introduce a new `Evaluate` trait that is implemented
by all COBs, and we make change graph evaluation fallible.
Doing this means that we get `apply` errors returned for free when an
invalid transaction is applied, and no longer need to check for action
validity in multiple places.
We also implement a new `Dag::prune` method to avoid having to copy
graph nodes during traversal.
It happened that a small bug in the remote helper caused a patch not to
merge correctly on push. Hence, I implemented a `rad-merge` tool for
these cases where we need to fix broken state.
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.
This change allows for files (blobs) to be embedded into COB entries.
This allows for things like image attachments in issue comments for example.
For now, we only enable this in the `issue` COB.
The way it works is that relevant COB actions carry metadata about which
files are attached to them; and we store those files as blobs inside the
COB entry's *tree* object, under an `embeds/` folder.
The `Embed<T>` type is used for the above, and either carries actual
content, or carries a content-id. Retrieving the actual content is as
simple as asking the repository for a blob with that content-id.
As a possible future extension, MIME types could be stored alongside the
files in a "metadata" file. This could help clients display the content
appropriately.
> 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.
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 new trait is used when only signing refs is needed, and not general
write access to a repository.
We also implement `ReadRepository` and `SignRepository` for
`DraftStore`.
The additional flexibility in choosing a backend for the COB store will
allow things like "draft" COBs that are stored in a different location,
without changing much of the logic.
This patch incorporates several important changes to code review:
* Code review verdict is no longer editable
* Made reviews redactable instead
* Renamed review top-level comment to "summary"
* Renamed inline comments to "comments"
* Made inline comments addressable by `EntryId`
* This is to allow for editing
* Removed inline comments from review creation
* Added a `CodeComment` action instead
* Removed `Semilattice` instance from `Review`
* Added a `EditReview` action instead to have more control
* Made it valid for revisions to be redacted concurrently with a review/merge
Most of these changes are needed to support proper inline code comments.
There were a few subtle issues with the apply logic of certain COBs
that should be fixed now.
Note that the underlying store guarantees exactly-once delivery, and so
it does not make sense to test idempotence at the patch level.
* `CodeLocation` had a `blob` and `commit` field. These are redundant,
since the review lives under a revision.
We also change the line range to be diff-compatible, with an old and
new range. The ranges are optional to account for different scenarios
like file deletion, move etc.
* `CodeComment` had redundant getters which were removed in favor of
public fields. We also remove the `timestamp` field, as it will be
the same as the review timestamp.
We test to make sure that in the event of concurrent operations,
traversal order is deterministic.
This required some changes to the testing infrastructure. We're also
able to simplify the `Actor` type that now has redundant functionality.
