I realized that somehow, the `git` executable is able to compute `git
status` much more quickly than libgit2, so I've switched our git status
logic to use `git`. Follow-up to
https://github.com/zed-industries/zed/pull/12266.
Release Notes:
- Improved the performance of git status updated when working in large
git repositories.
This PR increases the length of a shortened Git SHA from 6 to 7
characters.
This matches what GitHub uses.
I also took the opportunity to factor out a common method for computing
a short SHA so that we have a single source of truth for the length that
we're using.
Release Notes:
- Increased the short commit SHA length used by git blame from 6 to 7
characters.
This PR adds a registry for `GitHostingProvider`s.
The intent here is to help decouple these provider-specific concerns
from the lower-level `git` crate.
Similar to languages, the Git hosting providers live in the new
`git_hosting_providers` crate.
This work also lays the foundation for if we wanted to allow defining a
`GitHostingProvider` from within an extension. This could be useful if
we wanted to extend the support to work with self-hosted Git providers
(like GitHub Enterprise).
I also took the opportunity to move some of the provider-specific code
out of the `util` crate, since it had leaked into there.
Release Notes:
- N/A
This PR refactors the code pertaining to Git hosting providers to make
it more uniform and easy to add support for new providers.
There is now a `GitHostingProvider` trait that contains the
functionality specific to an individual Git hosting provider. Each
provider we support has an implementation of this trait.
Release Notes:
- N/A
This adds a new action to the editor: `editor: toggle git blame`. When
used it turns on a sidebar containing `git blame` information for the
currently open buffer.
The git blame information is updated when the buffer changes. It handles
additions, deletions, modifications, changes to the underlying git data
(new commits, changed commits, ...), file saves. It also handles folding
and wrapping lines correctly.
When the user hovers over a commit, a tooltip displays information for
the commit that introduced the line. If the repository has a remote with
the name `origin` configured, then clicking on a blame entry opens the
permalink to the commit on the code host.
Users can right-click on a blame entry to get a context menu which
allows them to copy the SHA of the commit.
The feature also works on shared projects, e.g. when collaborating a
peer can request `git blame` data.
As of this PR, Zed now comes bundled with a `git` binary so that users
don't have to have `git` installed locally to use this feature.
