This PR finishes up the support for generating commit messages using an
LLM.
We're shelling out to `git diff` to get the diff text, as it seemed more
efficient than attempting to reconstruct the diff ourselves from our
internal Git state.

Release Notes:
- Git Beta: Added support for generating commit messages using a
language model.

Release Notes:
- Git Beta: Fixed a bug where discarding a hunk in the project diff view
performed two concurrent saves of the buffer.
- Git Beta: Fixed an issue where diff hunks appeared in the wrong state
after failing to write to the git index.
Closes#25976
There's a couple states that this covers:
- upon `git init`, no footer is shown at all
- after 1 commit (or when on any parentless commit), the uncommit button
is ~disabled~ hidden
- otherwise commit button is shown
Also updated the button with "meta" tooltip showing human readable
description and git command.

Closes https://github.com/zed-industries/zed/issues/25865
Closes https://github.com/zed-industries/zed/pull/25915
In the issue, Zed had caused `.git/lfs/tmp/466102258`-like files to
appear in the directory, which lead to background FS event listener to
handle this as an update, incrementing snapshot's `scan_id`, which lead
to git status rescan, which caused another increment to `status_scan_id`
— incrementing either of the IDs causes the related repo data to be
considered "changed:
41b45eaba7/crates/worktree/src/worktree.rs (L1590-L1605)
hence propagating events to the other parts of the system (e.g. git
blame, which was also active in the issue's case)
```
[2025-03-01T20:01:08+01:00 DEBUG worktree] ignoring event ".git/lfs/tmp/466102258" within unloaded directory
[2025-03-01T20:01:08+01:00 DEBUG worktree] received fs events []

[2025-03-01T20:01:08+01:00 DEBUG editor::blame] Status of git repositories updated. Regenerating blame data...
```
Due to repo update events sent, another `.git/lfs/tmp/` entry is
created, things start over...
The PR fixes this by ignoring any `.git/lfs/` directory-related FS
events, as needed for the current git status update heuristics.
https://github.com/zed-industries/zed/pull/25915 tried to follow further
and `scan_id` and `status_scan_id` but we do not store all git state in
memory, e.g. head
e0060b92cc/crates/editor/src/editor_tests.rs (L13686)
as
[tests](https://github.com/zed-industries/zed/actions/runs/13631960559/job/38101504549?pr=25915)
show.
Release Notes:
- Improved `.git` scan heuristics
This PR adds toasts for reporting success and errors from remote git
operations. This PR also adds a focus handle to notifications, in
anticipation of making them keyboard accessible.

### Problem
When using HTTPS remotes, users are getting errors when trying to push
or pull via the git panel.
On macOS, Zed bundles a `git` binary that's part of
[`dugite-native`](https://github.com/desktop/dugite-native). But we
don't include the entire package. Additional binaries from
`dugite-native` are needed for pulling and pushing over HTTPS.
### Solution
Rather than bundling those additional binaries, I've changed the `push`,
`pull`, and `fetch` actions to rely on the *system-installed* `git`
binary. The downside of this is that, if the user does not have Git
installed, they wont' be able to push, pull, or fetch from within Zed.
But we believe that the vast majority of users will have Git installed.
Also, unlike `diff` and `status`, which Zed needs to call in the
background without any user interaction, `push`/`pull` and `fetch` are
explicit actions that the user takes in Zed, so there is an opportunity
to prompt them to install Git if they haven't.
### Background
There are three ways (that I know of) that users might authenticate when
pushing, pulling, or fetching over HTTPS.
1. Via a built-in [Git
`credential.helper`](https://git-scm.com/docs/gitcredentials). On macOS,
Git ships with a helper called `credential-osxkeychain` that stores
internet passwords in the OS Keychain. You can opt into this globally
with the command `git config --global credential.helper osxkeychain`,
which writes to your `~/.gitconfig`.
2. Via [`Git Credential Manager`
(GCM)](https://github.com/git-ecosystem/git-credential-manager), which
is a different `credential.helper`, [built by
GitHub](https://github.blog/security/application-security/git-credential-manager-authentication-for-everyone/),
which must be installed manually, and integrates with specific Git
hosting providers like GitHub and Azure.
3. By typing their Username and Password/Access-token interactively when
pushing/pulling/fetching.
### Testing Status
* [ ] 🚫 Interactive password auth - not yet supported, requires
https://github.com/zed-industries/zed/pull/25848
* [x] **credential-osxkeychain** - when using the built-in credential
helper, and the credentials are already stored in the keychain,
push/pull/fetch now work fine .
* [ ] **GCM** - still testing.
* Right now, I'm seeing `git-credential-manager` just hang indefinitely
when pushing from Zed, even though it works when pushing from a
terminal.
Release Notes:
- N/A
This PR adds the `whole_excerpt` field to the actions:
- `git::StageAndNext`
- `git::UnstageAndNext`
Which is set by false by default, effectively, now staging and unstaging
with these actions is done hunk-by-hunk, this also affects the `Stage`
and
`Unstage` buttons in the Diff View toolbar.
A caveat: with this PR, there is no way to configure the buttons in the
Diff
View toolbar to restore the previous behavior, if we want, I think we
can make
it a setting, but let's see if anyone really wants that.
Release Notes:
- N/A
This PR updates the ui of the git panel. It removes the header from the
panel and unifies the repository, branch and commit controls in the
bottom section.
It also adds a secondary menu to the primary button giving access to a
variety of actions for managing local and remote changes:
Known issues (will be fixed in a later pr)
- Spinner showing git operation progress was removed, will be re-added
- Clicking expand with the panel editor focused will commit (due to
shared action name. Already tracked)
Before | After
(Also adds `component`, `linkme` to cargo-machete ignore as they are
used in the `IntoComponent` proc-macro and will always be incorrectly
flagged as unused)

This was originally a part of another PR, but I wanted to get the
refactoring in and shift focus to working on bugs.
This causes all git commands via the `Repository` entity to be
serialized, and allows us to return values other than `Result<()>`

Closes #ISSUE
Release Notes:
- Rename `editor::RevertSelectedHunks` and `editor::RevertFile` to
`git::Restore` and `git::RestoreFile` for consistency with git
For symlinks, return `None` from `load_committed_text` as we do from
`load_index_text` ever since #10037.
Release Notes:
- Fixed diff hunks appearing in unchanged symlinked files
Adds the non-entry specific right click menu to the panel, and the
features contained therin:
* Stage all
* Discard Tracked Changes
* Trash Untracked Files
Also changes the naming from "Changes"/"New" to better match Git's
terminology (though not convinced on this, it was awkward to describe
"Discard Changes" without a way to distinguish between the changes and
the files containing them).
Release Notes:
- N/A
`refs/heads/*` doesn't match e.g. `refs/heads/cole/branch-with-slash`
(thanks fnmatch), but `refs/heads/**/*` does. This also works for
several levels of slash.
Release Notes:
- N/A
- [x] Staging hunks
- [x] Unstaging hunks
- [x] Write a randomized test
- [x] Get test passing
- [x] Fix existing bug in diff_base_byte_range computation
- [x] Remote project support
- [ ] ~~Improve performance of
buffer_range_to_unchanged_diff_base_range~~
- [ ] ~~Bug: project diff editor scrolls to top when staging/unstaging
hunk~~ existing issue
- [ ] ~~UI~~ deferred
- [x] Tricky cases
- [x] Correctly handle acting on multiple hunks for a single file
- [x] Remove path from index when unstaging the last staged hunk, if
it's absent from HEAD, or staging the only hunk, if it's deleted in the
working copy
Release Notes:
- Add `ToggleStagedSelectedDiffHunks` action for staging and unstaging
individual diff hunks
Git Panel updates:
* Fixes commit/commit all button to work (and be disabled correctly in
merge conflict status)
* Updates keyboard shortcuts and sets focus on the button (enter now
does the same as click; tab cycles between editor and change list)

This is a refactoring PR that does three things:
- First, it introduces a new `diff` crate that holds the previous
contents of the `git::diff` module, plus the `BufferChangeSet` type
formerly of `project::buffer_store`. The new crate is necessary since
simply moving `BufferChangeSet` into `git::diff` results in a dependency
cycle due to the use of `language::Buffer` to represent the diff base in
`BufferChangeSet`.
- Second, it renames the two main types in the new diff crate:
`BufferDiff` becomes `BufferDiffSnapshot`, and `BufferChangeSet` becomes
`BufferDiff`. This reflects that the relationship between these two
types (immutable cheaply-cloneable "value" type + stateful "resource
type" with subscriptions) mirrors existing pairs like
`Buffer`/`BufferSnapshot`. References to "change sets" throughout the
codebase are updated to refer to "diffs" instead.
- Finally, it moves the base_text field of the new BufferDiff type to
BufferDiffSnapshot.

`COMMIT_EDITMSG` language-related definitions (thanks @d1y )
Instead of using real `.git/COMMIT_EDITMSG` file, create a buffer

regular way via the `BufferStore`.
Adds a knowledge of what `Git Commit` language is, and uses it in the
buffers which are rendered in the git panel.

- Git: update diffs to be relative to HEAD instead of the index; to pave
the way for showing which hunks are staged
---------
Co-authored-by: Cole <cole@zed.dev>
This PR builds on #21258 to make it possible to use HEAD as a diff base.
The buffer store is extended to support holding multiple change sets,
and collab gains support for synchronizing the committed text of files
when any collaborator requires it.
Not implemented in this PR:
- Exposing the diff from HEAD to the user
- Decorating the diff from HEAD with information about which hunks are
staged
`test_random_multibuffer` now fails first at `SEED=13277`, similar to
the previous high-water mark, but with various bugs in the multibuffer
logic now shaken out.

Now all users in the collab/ssh session can edit the commit input
collaboratively, observing each others' changes live.
A real `.git/COMMIT_EDITMSG` file is opened, which automatically enables
its syntax highlight, but its original context is never used or saved on
disk — this way we avoid stale commit messages from previous commits
that git places there.
A caveat: previous version put some effort into preserving unfinished
commit messages on repo swtiches, but this version would not do that
— instead, it will be blank on startup, and use whatever
`.git/COMMIT_EDITMSG` contents on repo switch

This PR removes the `em_width` and `em_advance` parameters to
`EditorSnapshot::gutter_dimensions` in favor of computing the values
inside of it.
In practice all of the callers were passing in the same values, and
there isn't a circumstance where we would want to pass in different
values.
`gutter_dimensions` has also been modified to return
`Option<GutterDimensions>` instead of `GutterDimensions` so that we can
remove some `.unwrap`s when interacting with the text system.

Follow-up of https://github.com/zed-industries/zed/pull/23869
* Retrieves user + email for collab project clients and use these when
such users commit
Same as in https://github.com/zed-industries/zed/pull/23329, "is it the
right user name and e-mail" and "how to override these" questions apply.
* If this data is unavailable, forbid committing to the remote client
* Forbid running related actions in git panel, if committing/writing is
not permitted

A preparation for collaborative commit message editing.
Before, almost any `.git`-contained file FS update, except
`.git/fsmonitor--daemon/cookies/**` caused git metadata rescan.
This included `index.lock` that was created after any git operation,
e.g. `git status`, which was unnecessary.
Collaborative editing aims to share `.git/COMMIT_EDITMSG` between
multiple users, so there are potentially multiple users editing the file
and causing excessive events.
The change makes worktree to ignore .git/COMMIT_EDITMSG`,
`.git/index.lock` and `.git/fsmonitor--daemon/**` paths and adjusts the
logic to be more extensible: there's much more files Zed can ignore and
still have its git metadata up to date.

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs

Closes#12553
* [x] Fix `diff_hunk_before`
* [x] Fix failure to show deleted text when expanding hunk w/ cursor on
second line of the hunk
* [x] Failure to expand diff hunk below the cursor.
* [x] Delete the whole file, and expand the diff. Backspace over the
deleted hunk, panic!
* [x] Go-to-line now counts the diff hunks, but it should not
* [x] backspace at the beginning of a deleted hunk deletes too much text
* [x] Indent guides are rendered incorrectly
* [ ] Fix randomized multi buffer tests
Maybe:
* [ ] Buffer search should include deleted text (in vim mode it turns
out I use `/x` all the time to jump to the next x I can see).
* [ ] vim: should refuse to switch into insert mode if selection is
fully within a diff.
* [ ] vim `o` command when cursor is on last line of deleted hunk.
* [ ] vim `shift-o` on first line of deleted hunk moves cursor but
doesn't insert line
* [x] `enter` at end of diff hunk inserts a new line but doesn't move
cursor
* [x] (`shift-enter` at start of diff hunk does nothing)
* [ ] Inserting a line just before an expanded hunk collapses it
Release Notes:
- Improved diff rendering, allowing you to navigate with your cursor
inside of deleted text in diff hunks.

When a file exists in HEAD, is deleted in the index, and exists again in
the working copy, git produces two lines for it, one reading `D `
(deleted in index, unmodified in working copy), and the other reading
`??` (untracked). Merge these two into the equivalent of `DA`.
Release Notes:
- Improved handling of files that are deleted in the git index but exist
in HEAD and the working copy
The output of `git status --porcelain=v1` includes untracked
directories, i.e. directories that have no tracked files beneath. Since
we have our own way of computing a "summary" status for each directory
in a repo, this is not helpful for Zed; and it interferes with our
handling of nested repos. So just skip these lines in the output.
Closes#23133
Release Notes:
- Fix project panel colors when one git repository is nested beneath
another
- [x] Basic implementation
- [x] Disable commit buttons when committing is not possible (empty
message, no changes)
- [x] Upgrade GitSummary to efficiently figure out whether there are any
staged changes
- [x] Make CommitAll work
- [x] Surface errors with toasts
- [x] Channel shutdown
- [x] Empty commit message or no changes
- [x] Failed git operations
- [x] Fix added files no longer appearing correctly in the project panel
