This adds support for [git
worktrees](https://matklad.github.io/2024/07/25/git-worktrees.html). It
fixes the errors that show up (git blame not working) and actually adds
support for detecting git changes in a `.git` folder that's outside of
our path (and not even in the ancestor chain of our root path).
(While working on this we discovered that our `.gitignore` handling is
not 100% correct. For example: we do stop processing `.gitignore` files
once we found a `.git` repository and don't go further up the ancestors,
which is correct, but then we also don't take into account the
`excludesFile` that a user might have configured, see:
https://git-scm.com/docs/gitignore)
Closes https://github.com/zed-industries/zed/issues/19842
Closes https://github.com/zed-industries/zed/issues/4670
Release Notes:
- Added support for git worktrees. Zed can now open git worktrees and
the git status in them is correctly handled.

This PR improves the parsing of Git remote URLs in order to make
features that depend on them more robust.
Previously we were just treating these as plain strings and doing
one-off shotgun parsing to massage them into the right format. This
meant that we weren't accounting for edge cases in URL structure.
One of these cases was HTTPS Git URLs containing a username, which can
arise when using GitHub Enterprise (see
https://github.com/zed-industries/zed/issues/11160).
We now have a `RemoteUrl` typed to represent a parsed Git remote URL and
use the `Url` parser to parse it.
Release Notes:
- Improved the parsing of Git remote URLs to support additional
scenarios.
This PR adds support for self-hosted GitLab instances when generating
Git permalinks.
If the `origin` Git remote contains `gitlab` in the URL hostname we will
then attempt to register it as a self-hosted GitLab instance.
A note on this: I don't think relying on specific keywords is going to
be a suitable long-term solution to detection. In reality the
self-hosted instance could be hosted anywhere (e.g.,
`vcs.my-company.com`), so we will ultimately need a way to have the user
indicate which Git provider they are using (perhaps via a setting).
Closes https://github.com/zed-industries/zed/issues/18012.
Release Notes:
- Added support for self-hosted GitLab instances when generating Git
permalinks.
- The instance URL must have `gitlab` somewhere in the host in order to
be recognized.
We are going to use this in the multi-buffer to produce a summary for an
`Excerpt` that contains a `Range<Anchor>`.

Add `/auto` behind a feature flag that's disabled for now, even for

base even if they're unused for now.

***Update**: after rebasing on top of
https://github.com/zed-industries/zed/pull/16915/ (that also changed how
search worked), the results are still good, but not 10x. Instead of
going from 10s to 500ms, it goes from 10s to 3s.*
This improves the performance of project-wide search by an order of
magnitude.
After digging in, @as-cii and I found that opening buffers was the
bottleneck for project-wide search (since Zed opens, parses, ... buffers
when finding them, which is something VS Code doesn't do, for example).
So this PR improves the performance of opening multiple buffers at once.
It does this by doing two things:
- It batches scan-requests in the worktree. When we search, we search
files in chunks of 64. Previously we'd handle all 64 scan requests
separately. The new code checks if the scan requests can be batched and
if so it, it does that.
- It batches `git status` calls when reloading the project entries for
the opened buffers. Instead of calling `git status` for each file, it
calls `git status` for a batch of files, and then extracts the status
for each file.
(It has to be said that I think the slow performance on `main` has been
a regression introduced over the last few months with the changes made
to project/worktree/git. I don't think it was this slow ~5 months ago.
But I also don't think it was this fast ~5 months ago.)
## Benchmarks

Previously, each git `Repository` object was held inside of a mutex.
This was needed because libgit2's Repository object is (as one would
expect) not thread safe. But now, the two longest-running git operations
that Zed performs, (`status` and `blame`) do not use libgit2 - they
invoke the `git` executable. For these operations, it's not necessary to
hold a lock on the repository.
In this PR, I've moved our mutex usage so that it only wraps the libgit2
calls, not our `git` subprocess spawns. The main user-facing impact of
this is that the UI is much more responsive when initially opening a
project with a very large git repository (e.g. `chromium`, `webkit`,
`linux`).
Release Notes:
- Improved Zed's responsiveness when initially opening a project
containing a very large git repository.
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
Notable things I've had to fix due to 1.78:
- Better detection of unused items
- New clippy lint (`assigning_clones`) that points out places where assignment operations with clone rhs could be replaced with more performant `clone_into`

As an attempt to do things better when showing diff hunks, store diff
base as Rope, not String, to have cheaper clones when the diff base text
is reused, e.g. creating another buffer with the diff base text for hunk

Added two new actions with the default keybindings
```
"cmd-'": "editor::ToggleHunkDiff",
"cmd-\"": "editor::ExpandAllHunkDiffs",
```
that allow to browse git hunk diffs in Zed:
https://github.com/zed-industries/zed/assets/2690773/9a8a7d10-ed06-4960-b4ee-fe28fc5c4768
The hunks are dynamic and alter on user folds and modifications, or
toggle hidden, if the modifications were not adjacent to the expanded
hunk.
Release Notes:
- Added `editor::ToggleHunkDiff` (`cmd-'`) and
`editor::ExpandAllHunkDiffs` (`cmd-"`) actions to browse git hunk diffs
in Zed
Release Notes:
- Added support for avatars in git blame for repositories hosted on
codeberg

Questions:
- Should we move git stuff like `Commit`, `Author`, etc outside of
hosting-specific files (I don't think so, as other hostings can have
different stuff)
- Should we also add support for self hosted forgejo instances or should
it be a different PR?
This is a follow-up to #10685 which started to hide these errors instead
of displaying them to the user.
But the errors are still noisy and not actionable, so we hide them
instead.
Release Notes:
- Removed error message being logged when `git blame` is run in a
repository without commits.

This fixes useless error messages popping up in case a file hasn't been
committed yet or the repo doesn't have commits yet.

Release Notes:
- Added a notification to show possible `git blame` errors if it fails to run.
Caveats:
- ~git blame now executes in foreground
executor (required since the Fut is !Send)~
TODOs:
- After a failed toggle, the app thinks the blame
is shown. This means toggling again will do nothing
instead of retrying. (Caused by editor.show_git_blame
being set to true before the git blame is generated)
- ~(Maybe) Trim error?~ Done

Release notes:
- Fixed a crash when joining two consecutive lines
([#9692](https://github.com/zed-industries/zed/pull/9692)).
This crash is not caused by `vim` or `editor`'s code logic, `join_line`
logic is okay, I found that the crash is caused by a refresh of git
`diff` after every update, hhen git diff generates hunks, it will look
for the cursor to the beginning of a line, and judge that if the cursor
result column is greater than 0, that is, it is not the beginning of a
line, it will correct the row to the next line, I think before we forgot
here that I need to adjust the column to 0 at the same time, otherwise
it is easy to go out of bounds, I am not sure if I need to add more
tests for this method, I can add if I need to, but I feel that this case
is a bit extreme

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.
### Screenshots
### TODOs
- [x] Bundling `git` binary
### Release Notes
Release Notes:
- Added `editor: toggle git blame` command that toggles a sidebar with
git blame information for the current buffer.

This PR moves the Clippy configuration up to the workspace level.
We're using the [`lints`
table](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-lints-table)
to configure the Clippy ruleset in the workspace's `Cargo.toml`.
Each crate in the workspace now has the following in their own
`Cargo.toml` to inherit the lints from the workspace:
```toml
[lints]
workspace = true
```
This allows for configuring rust-analyzer to show Clippy lints in the
editor by using the following configuration in your Zed `settings.json`:
```json
{
"lsp": {
"rust-analyzer": {
"initialization_options": {
"check": {
"command": "clippy"
}
}
}
}
```
