This PR updates our DB schemas and wire protocol to separate the
synchronization of git statuses and other repository state from the
synchronization of worktrees. This paves the way for moving the code
that executes git status updates out of the `worktree` crate and onto
the new `GitStore`. That end goal is motivated by two (related) points:
- Disentangling git status updates from the worktree's
`BackgroundScanner` will allow us to implement a simpler concurrency
story for those updates, hopefully fixing some known but elusive bugs
(upstream state not updating after push; statuses getting out of sync in
remote projects).
- By moving git repository state to the project-scoped `GitStore`, we
can get rid of the duplication that currently happens when two worktrees
are associated with the same git repository.

This PR reworks the `FakeGitRepository` type that we use for testing git
interactions, to make it more realistic. In particular, the `status`
method now derives the Git status from the differences between HEAD, the
index, and the working copy. This way, if you modify a file in the
`FakeFs`, the Git repository's `status` method will reflect that
modification.

This is the core change:
https://github.com/zed-industries/zed/pull/26758/files#diff-044302c0d57147af17e68a0009fee3e8dcdfb4f32c27a915e70cfa80e987f765R1052
TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code

This PR adds a failing test `test_staging_hunks_with_delayed_fs_event`
and makes it pass
Also skips a queued read for git diff states if another read was
requested (less work)
This still doesn't catch all race conditions, but the PR is getting long
so I'll yield this and start another branch
Release Notes:
- N/A
This was added in #8343 to make it only visible for tests. #9189 then
made it visible regardless of `test-support`, so the definitions became
identical.

I thought it might be just `test_file_status` this time, but it seems to
be all four of the tests that we were previously seeing issues with.

This moves spawning of the git subprocess to the main thread. We're not
yet
sure why, but when we spawn a process using GCD's background queues,
sub-processes like git-credential-manager fail to open windows.
This seems to be fixable either by using the main thread, or by using a
standard background thread,
but for now we use the main thread.
Release Notes:
- Git: Fix git-credential-manager

This reduces the number of multibuffer syncs from 100,000 to 20,000.
Before this change each editor individually observed the project, so
literally any project change was amplified by the number of editors you
had open.
Now editors listen to their buffers instead of the project, and other
users of `cx.observe` on the project have been updated to use specific
events to reduce churn.
Follow up to #26237
Release Notes:
- Improved performance of Zed in large repos with lots of file system
events.

Modified version of #25950. We still use worktree paths, but repo paths
with a status that lie outside the worktree are not excluded; instead,
we relativize them by adding `..`. This makes the list in the git panel
match what you'd get from running `git status` (with the repo's worktree
root as the working directory).
- [x] Implement + test new unrelativization logic
- [x] ~~When collecting repositories, dedup by .git abs path, so
worktrees can share a repo at the project level~~ dedup repos at the
repository selector layer, with repos coming from larger worktrees being
preferred
- [x] Open single-file worktree with diff when activating a path not in
the worktree

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.

Attempt to fix an issue where conflicts from a cherry-pick don't get
cleared out of the git panel after being resolved.
Release Notes:
- Git Beta: Fixed resolution of conflicts from cherry-picks not being
reflected in the git panel
When a worktree is created, we walk up the ancestors of the root path
trying to find a git repository. In particular, if your `$HOME` is a git
repository and you open some subdirectory of `$HOME` that's *not* a git
repository, we end up scanning `$HOME` and everything under it looking
for changed and untracked files, which is often pretty slow. Consistency
here is not very useful and leads to a bad experience.
This PR adds a special case to not consider `$HOME` as a containing git
repository, unless you ask for it by doing the equivalent of `zed ~`.
Release Notes:
- Changed the behavior of git features to not treat `$HOME` as a git
repository unless opened directly
We've had some issues reported with git repositories not getting
detected when they're a strict parent of the worktree root. Add a bit
more logging to understand what's going on here.

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)
```

```
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.

- Improved `.git` scan heuristics
Like the real app, this one infinite loops if you have a diff in an
UnsharedFile.

This PR uses the template merge message in `.git/MERGE_MSG` to populate
the commit message buffer in the git panel. This is done:
- when the commit message buffer is first created
- when the list of merge heads in .git changes, only if the buffer
doesn't already have some text in it
Hopefully this strikes a good balance between convenience and not
stomping on the user's toes.

Follow-up of https://github.com/zed-industries/zed/pull/24307
Brings back the PR and fixes the issue with the git status not
propagated, if computed too slow.
Now, git repo update
* waits in the background for all `scan_dir` repo status updates and
triggers another status update send afterwards
* ensures that the update sent is reported correctly (`scanning = true`)
if either FS or status scan is running still
* during worktree's git statuses updates, bumps `status_scan_id` to
ensure the repo update is reported to all subscribers
Release Notes:
- Improved project panel's speed in large projects
Closes#10232
Context:
We have three ways to open files or dirs in Zed: `zed`, `zed --new`, and
`zed --add`. `--new` forces the project to open in a new window, while
`--add` forces it to open in an existing window (even if the dir isn’t a
subdir of an existing project or the file isn’t part of it).
Using just `zed` tries to open it in an existing window based on similar
logic of `--add`, but if no related project is found the dir, opens in a
new window.
Problem:
Right now, subdirs that are part of an existing project open in the
existing window when using `zed`. By default, subdirs should open in a
new window instead. If someone wants to open it in the existing window,
they can explicitly use `--add`. After this PR, only root dir and files
will focus on existing window, when `zed ` is used.
Fix:
For the `zed` case, we’ve filtered out subdirs in the logic that assigns
them to an existing window.
Release Notes:
- Fixed an issue where subdirectories of an already opened project, when
opened via the terminal, would open in the existing project instead of a
new window.
Closes#7923
This PR fixes root worktree renaming by:
1. Handling the case where `new_path` is the new root name instead of a
relative path from the root.
2. [#20313](https://github.com/zed-industries/zed/pull/20313) added
functionality to watch for root worktree renames made externally, e.g.,
via Finder. This PR avoids relying on that watcher because, when
renaming explicitly from Zed, we can eagerly perform the necessary work
(of course after fs rename) instead of waiting for the watcher to detect
the rename. This prevents UI glitches during renaming root.
Todo:
- [x] Fix wrong abs paths when root is renamed
- [x] Fix explicit scan entry func to handle renamed root dir
- [x] Tests
- [x] Test on Linux
- [x] Tested with single and multipe worktrees
- [x] Tested when single file is root file
Release Notes:
- Fixed an issue where worktree root name couldn't be renamed in project
panel.
This PR adds the branch selector to the git panel and fixes a few bugs
in the repository selector.

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.

Go back to a less optimized implementation for now since the custom
cursor target seems to have some bugs.
Release Notes:
- Fixed missing git blame and status output in some projects with
multiple git repositories
Rework of https://github.com/zed-industries/zed/pull/24130
Uses

`COMMIT_EDITMSG` language-related definitions (thanks @d1y )
Instead of using real `.git/COMMIT_EDITMSG` file, create a buffer
without FS representation, stored in the `Repository` and shared the
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.

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.
