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 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

### DISCLAIMER
> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.

Follow-up of https://github.com/zed-industries/zed/pull/26410
* Extract word completions into their own, `editor::ShowWordCompletions`
action so those could be triggered independently of completions
* Assign `ctrl-shift-space` binding to this new action
* Still keep words returned along the completions as in the original PR,
but:
* Tone down regular completions' fallback logic, skip words when the
language server responds with empty list of completions, but keep on
adding words if nothing or an error were returned instead
* Adjust the defaults to wait for LSP completions infinitely
* Skip "words" with digits such as `0_usize` or `2.f32` from completion
items, unless a completion query has digits in it
Release Notes:

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.
This PR adds an optimistic update when staging or unstaging diff hunks.
In the process, I've also refactored the logic for staging and unstaging
hunks, to consolidate more of it in the `buffer_diff` crate.
I've also changed the way that we treat untracked files. Previously, we
maintained an empty diff for them, so as not to show unwanted
entire-file diff hunks in a regular editor. But then in the project diff
view, we had to account for this, and replace these empty diffs with
entire-file diffs. This form of state management made it more difficult
to store the pending hunks, so now we always use the same
`BufferDiff`/`BufferDiffSnapshot` for untracked files (with a single
hunk spanning the entire buffer), but we just have a special case in
regular buffers, that avoids showing that entire-file hunk.
* [x] Avoid creating a long queue of `set_index` operations when
staging/unstaging rapidly
* [x] Keep pending hunks when diff is recalculated without base text
changes
* [x] Be optimistic even when staging the single hunk in added/deleted
files
* Testing

Follow-up of https://github.com/zed-industries/zed/pull/25605
Previous PR made global tasks with `ZED_WORKTREE_ROOT` available for
"nothing open" scenario, this PR also gets all related worktree task
templates, using the centralized `TextContexts`' active worktree
detection.
Release Notes:
- N/A
Closes https://github.com/zed-industries/zed/issues/22912
Reworks the task context infrastructure so that it's possible to have
multiple contexts at the same time, and stores all possible worktree
context there.
Task UI code is now falling back to the "active" worktree context, if
active item's context did not produce a resolved task.
Current code does not produce meaningful results for projects with
multiple worktrees to avoid ambiguity and design changes: instead of
resolving tasks per worktree context available, extra worktree context
is only used when resolving tasks from the same worktree.
Release Notes:
- Improved Zed tasks' `ZED_WORKTREE_ROOT` fallbacks
Closes https://github.com/zed-industries/zed/issues/10122
Closes https://github.com/zed-industries/zed/issues/25034
When formatting buffers or reloading them after they change on disk, we
performed a diff between the buffer's current contents and the new
content. We need this diff in order preserve the positions of cursors
and other decorations when updating the buffer's text.
In order to handle changes within lines, we would previously compute a
*character-wise* diff. This was extremely expensive for large files.
This PR gets rid of the character-wise diff, and instead performs a
normal line-wise diff. Then, for certain replace hunks, we compute a
secondary word-based diff. Also, I've switched to the
[`imara-diff`](https://github.com/pascalkuthe/imara-diff) crate, instead
of `similar`.
Release Notes:
- Fixed a hang that could occur when large files were changed on disk or
formatted.
Release Notes:
- Render unstaged hunks in the project diff editor with a slashed
background

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.

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.

In the Windows test environment, the paths generated by `temp_tree()`
are symlink paths, which causes certain tests to fail.
I later noticed that when opening a project, we seem to always use
`canonicalize` to normalize the paths, as shown here:
https://github.com/zed-industries/zed/pull/21039.
This PR adopts a similar approach for the test environment to address
the issue.

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.

This PR introduces a new entity called Project Tree which is responsible
for finding subprojects within a worktree;
a subproject is a language-specific subset of a worktree which should be
accurately tracked on the language server side. We'll have an ability to
set multiple disjoint workspaceFolders on language server side OR spawn
multiple instances of a single language server (which will be the case
with e.g. Python language servers, as they need to interact with
multiple disjoint virtual environments).
Project Tree assumes that projects of the same LspAdapter kind cannot
overlap. Additionally project nesting is not allowed within the scope of
a single LspAdapter.
Closes https://github.com/zed-industries/zed/issues/5108
Re-lands #22182 which I had to revert due to merging it into todays
Preview.
Release Notes:
- Language servers now track their working directory more accurately.

I've noticed an occasional error: `ignoring event C:\some\path\to\file
outside of root path \\?\C:\some\path`. This happens because UNC paths
always fail to match with non-UNC paths during operations like
`strip_prefix` or `starts_with`. To address this, I changed the types of
some key parameters to `SanitizedPath`. With this adjustment, FS events
are now correctly identified, and under the changes in this PR, the
`test_rescan_and_remote_updates` test also passes successfully on
Windows.
Release Notes:
- N/A
During my work on PR #22616, while trying to fix the
`test_reporting_fs_changes_to_language_servers` test case, I noticed
that we are currently handling paths using `String` in some places.
However, this approach causes issues on Windows.
This draft PR modifies `rebuild_watched_paths_inner` and
`glob_literal_prefix`. For example, take the `glob_literal_prefix`
function modified in this PR:
```rust
assert_eq!(
glob_literal_prefix("node_modules/**/*.js"),
"node_modules"
); // This works on Unix, fails on Windows
assert_eq!(
glob_literal_prefix("node_modules\\**\\*.js"),
"node_modules"
); // This works on Windows
assert_eq!(
glob_literal_prefix("node_modules\\**/*.js"),
"node_modules"
); // This fails on Windows
```
The current implementation treats path as `String` and relies on `\` as
the path separator on Windows, but on Windows, both `/` and `\` can be
used as separators. This means that `node_modules\**/*.js` is also a
valid path representation.
There are two potential solutions to this issue:
1. **Continue handling paths with `String`**, and on Windows, replace
all `/` with `\`.
2. **Use `Path` for path handling**, which is the solution implemented
in this PR.
### Advantages of Solution 1:
- Simple and direct.
### Advantages of Solution 2:
- More robust, especially in handling `strip_prefix`.
Currently, the logic for removing a path prefix looks like this:
```rust
let path = "/some/path/to/file.rs";
let parent = "/some/path/to";
// remove prefix
let file = path.strip_prefix(parent).unwrap(); // which is `/file.rs`
let file = file.strip_prefix("/").unwrap();
```
However, using `Path` simplifies this process and makes it more robust:
```rust
let path = Path::new("C:/path/to/src/main.rs");
let parent = Path::new("C:/path/to/src");
let file = path.strip_prefix(&parent).unwrap(); // which is `main.rs`
let path = Path::new("C:\\path\\to/src/main.rs");
let parent = Path::new("C:/path/to\\src\\");
let file = path.strip_prefix(&parent).unwrap(); // which is `main.rs`
```

This adds support for LSPs that use the old rename flow which does not
first ask the LSP for the rename range and check that it is a valid
range to rename.
Closes#16663
Release Notes:
* Fixed rename symbols action when the language server does not have the
capability to prepare renames - such as `luau-lsp`.
This reverts commit 3ae6aa0e4d.
If "group_id = 0" really did mean a diagnostic not from a language
server then various methods related to diagnostic set would need to be
updated. Something like [this
diff](https://gist.github.com/mgsloan/e902153bcaec207b39260a8f40d3134d).
Plan instead is to use InfoPopover instead of DiagnosticPopover for
these.
Release Notes:
- N/A
In particular, `DiagnosticPopover` both:
* Supports moving the selection to a diagnostic when clicked, based on
`group_id`
* Provides Diagnostic values with `group_id: 0` providing informztion on
hover about invisible characters.
So, clicking such a popover would navigate to the very first error
produced by a language server. Really not a big deal of course, but
seems good to fix as it might result in surprising behavior in other
future circumstances
Release Notes:
- N/A
Still TODO:
* [x] Factor out `start_language_server` so we can call it on register
(instead of on detect language)
* [x] Only call register in singleton editors (or when
editing/go-to-definition etc. in a multibuffer?)
* [x] Refcount on register so we can unregister when no buffer remain
* [ ] (maybe) Stop language servers that are no longer needed after some
time
Release Notes:
- Fixed language servers starting when doing project search
- Fixed high CPU usage when ignoring warnings in the diagnostics view

Closes#21564
Notably, RA will now rename module references if you change the source
file name via our project panel.
This PR is a tad bigger than necessary as I torn out the Model<> from
didSave watchers (I tried to reuse that code for the same purpose).
Release Notes:
- Added support for language server actions being executed on file
rename.
This is a pure refactor of our Git diff state management. Buffers are no
longer are associated with one single diff (the unstaged changes).
Instead, there is an explicit project API for retrieving a buffer's
unstaged changes, and the `Editor` view layer is responsible for
choosing what diff to associate with a buffer.
The reason for this change is that we'll soon want to add multiple "git
diff views" to Zed, one of which will show the *uncommitted* changes for
a buffer. But that view will need to co-exist with other views of the
same buffer, which may want to show the unstaged changes.
### Todo
* [x] Get git gutter and git hunks working with new structure
* [x] Update editor tests to use new APIs
* [x] Update buffer tests
* [x] Restructure remoting/collab protocol
* [x] Update assertions about staged text in
`random_project_collaboration_tests`
* [x] Move buffer tests for git diff management to a new spot, using the
new APIs

I've observed that Zed's implementation of [Code Actions On
Format](https://zed.dev/docs/configuring-zed#code-actions-on-format)
uses the
[CodeActionContext.only](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeActionContext)
parameter to request specific code action kinds from the server. The
issue is that it does not filter out code actions from the response,
believing that the server will do it.
The [LSP
specification](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeActionContext)
says that the client is responsible for filtering out unwanted code
actions:
```js
/**
* Requested kind of actions to return.
*
* Actions not of this kind are filtered out by the client before being
* shown. So servers can omit computing them.
*/
only?: CodeActionKind[];
```
This PR will filter out unwanted code action on the client side.
I have initially encountered this issue because the [ZLS language
server](https://github.com/zigtools/zls) (until
https://github.com/zigtools/zls/pull/2087) does not filter code action
based on `CodeActionContext.only` so Zed runs all received code actions
even if they are explicitly disabled in the `code_actions_on_format`
setting.
Release Notes:
- Fix the `code_actions_on_format` setting when used with a language
server like ZLS

Motivation for this is to make things more understandable while figuring
out #20775.
This is intended to be a refactoring that does not affect behavior, but
there are a few tricky spots:
* Previously `File.mtime()` (now `File.disk_state().mtime()`) would
return last known modification time for deleted files. Looking at uses,
I believe this will not affect anything. If there are behavior changes
here I believe they would be improvements.
* `BufferEvent::DirtyChanged` is now only emitted if dirtiness actually
changed, rather than if it may have changed. This should only be an
efficiency improvement.
