Sathwik Chirivelli 54fdf58d3a git_panel: Show staged and unstaged diff stats (#60815)
# Objective

- Show accurate diff stats for each staged and unstaged projection of a
partially staged file in the Git panel.
- This was originally considered for
https://github.com/zed-industries/zed/pull/59884, but was scoped out of
that already-large PR and is being submitted separately as discussed
there.

## Solution

- Collect HEAD-to-index and index-to-worktree diff stats alongside the
existing combined HEAD-to-worktree stats.
- Carry the staged and unstaged stats through repository status
snapshots and remote status serialization.
- Use the stat matching the projected Git panel section while preserving
the combined stat for the other grouping modes.
- Update the fake Git repository and add regression coverage with
deliberately different staged and unstaged counts.

## Testing

- `cargo check -p git_ui`
- `cargo check -p collab`
- `cargo test -p git_ui
test_group_by_staging_section_membership_and_order --lib`
- `cargo test -p project --lib --no-run`
- `cargo fmt --all -- --check`
- `git diff --check`

## Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content adheres to Zed's UI standards
([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
and
[icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md)
guidelines)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Jake AbendrothandCole Miller eb962794a3 buffer_diff: Canonicalize ambiguous hunk placement to fix staging corruption (#60584)
Closes #60424

## Problem

With the repro from #60424, staging the first deletion hunk marked the
second deletion as staged in the UI even though git still had it
unstaged, and clicking the (incorrectly shown) Unstage button inserted a
duplicate copy of the hunk's contents into the git index on every click.

The root cause is ambiguous hunk placement. The committed text contains
repeated `end\n\n` line runs, so the deletion hunks can "slide": more
than one placement produces a minimal diff. The uncommitted diff (HEAD
vs worktree) anchored the remaining deletion at one row while the
unstaged diff (index vs worktree), recomputed after the partial stage,
anchored the same logical deletion at a different row. Everything that
correlates hunks across those two diffs assumes they agree on positions:

- the secondary-status matching in `hunks_intersecting_range_impl` found
no unstaged hunk at the uncommitted hunk's rows and reported it as
staged (`NoSecondaryHunk`);
- the worktree→index projection in `compute_uncommitted_index_edits`
treated the hunk's position as unchanged text and, on unstage, inserted
the hunk's HEAD content at an index position that already contained it,
duplicating it on every request.

## Fix

Upgrade `imara-diff` from 0.1.8 to 0.2.0 and run
`Diff::postprocess_lines` (imara-diff's port of git's xdiff
slider/indent heuristic) after computing hunks in `buffer_diff`. This
canonicalizes the placement of ambiguous hunks based only on their local
content, so diffs of the same buffer against different base texts anchor
the same logical change at the same rows. A bonus is that Zed's hunk
placement now matches `git diff`'s output for such cases (git has used
the indent heuristic by default since 2.11).

As defense in depth, `compute_uncommitted_index_edits` now drops a
pure-insertion index edit whose content is already present at the target
position, so a stale secondary status can no longer duplicate index
content.

The imara-diff 0.2 API removed the `Sink` trait and the top-level
`diff()` function, so the other call sites (`language/text_diff.rs`,
`zeta_prompt/udiff.rs`, `edit_prediction_metrics/reversal.rs`) are
migrated mechanically to `Diff::compute` + `hunks()` with unchanged
behavior (0.2 also renamed `lines_with_terminator` to `lines` and
changed the default `&str` tokenization to include terminators; the
unified-diff builders keep terminator-less tokens via `str::lines()`).

## Testing

- New regression test `test_staging_hunks_with_ambiguous_placement`
replays the exact repro from #60424 (same file contents): stages the
first deletion, asserts the remaining hunks keep their unstaged status
and the index matches exactly, then issues repeated unstage requests for
the unstaged hunk and asserts the index is unchanged. Before the fix
this test showed the second hunk flipping to staged and the index
growing by one copy of the deleted block per unstage request.
- `buffer_diff`, `language`, `zeta_prompt`, `edit_prediction_metrics`,
`multi_buffer`, `git_ui`, `editor`, and the `project` integration suite
pass.
- One test expectation updated: `editor::test_fold_function_bodies`
asserted the old placement of an ambiguous deletion (blank line before
comment); the canonicalized placement (comment before blank line)
matches what `git diff` produces for the same texts.

Release Notes:

- Fixed staging a hunk sometimes marking a different hunk as staged (and
subsequent unstaging corrupting the git index) when the diff contained
repeated lines
([#60424](https://github.com/zed-industries/zed/issues/60424)).

Lukas Wirth c7148c8190 project: Fix agent hanging indefinitely when pulling workspace diagnostics (#61176)
The agent's diagnostics tool waits on pull_workspace_diagnostics_once,
which enqueues a completion signal into the background workspace
diagnostics refresh loop. When a language server failed to answer
workspace/diagnostic requests, that signal could be stranded, leaving
the agent stuck on 'Check project diagnostics' (reported with logs full
of 'Timeout during workspace diagnostics pull' and requests cancelled
after 120s).

Three hang paths in lsp_workspace_diagnostics_refresh:

1. Timeouts never resolved the completion signal. On
ConnectionResult::Timeout the loop just retried, holding the waiter
through up to 50 attempts x 120s each (~100 minutes) before the sender
was finally dropped.

2. Waiters could queue behind an already-hanging request. The refresh
channel has capacity 1; if the loop was mid-retry (e.g. the initial pull
at server startup was timing out), a newly enqueued waiter sat
unreceived until the entire retry cycle ended.

3. The request timeout was permanently disabled after the first partial
result. The timer raced progress_rx.recv() once and became pending()
forever if progress won, so a server that streamed one chunk and then
stalled hung the request indefinitely.

Fixes:

- On timeout, release all pending waiters (including ones that queued
mid-flight) with refreshed = false, so callers fall back to cached
diagnostics after at most one timeout period while the background loop
keeps retrying.

- Carry waiters as a Vec and absorb refresh requests queued during
backoff/in-flight requests into the current attempt instead of
serializing them behind it.

- Restart the timeout whenever a partial result arrives, turning it into
an inactivity timeout: streaming servers get unlimited total time while
they keep making progress, but a stalled stream now times out instead of
hanging forever.

Adds a regression test with a fake server that never answers workspace
diagnostic pulls, verifying the waiter resolves after the timeout; it
fails with 'Parking forbidden' (infinite hang) without the fix.

Closes FR-124

Release Notes:

- Fixed agents hanging indefinitely if an LSP server never responds to
diagnostics requests

Xin Zhao c7b43b20b4 project: Persist workspace diagnostics when closing buffer (#59875)
# Objective

Closes #50739

Many language servers have settings for their diagnostic mode, typically
supporting either "single file" mode or "workspace" mode.

In single file mode, the language server only generates diagnostics for
files that the user has open. When a file is closed, those diagnostics
are cleared. This is the behavior currently implemented in Zed.

However, when a language server runs in workspace mode, we should retain
all diagnostics regardless of whether the corresponding file is open or
closed. As reported in #50739, Zed currently discards these diagnostics
when a buffer is closed, just like in single file mode.

When a buffer is completely closed, Zed triggers a diagnostics update to
perform cleanup:

https://github.com/zed-industries/zed/blob/8372eb1b131ab3b8c0622e930e985f15eb970687/crates/project/src/lsp_store.rs#L4747-L4773
and the Pulled diagnostics are all cleaned, that's why when closing a
buffer, the diagnostic summary disappeared. This process aggressively
clears all `Pulled` diagnostics, causing the diagnostic summary for the
closed file to disappear.

## Solution

Filter the target language servers when updating diagnostics on buffer
close. If a language server has workspace diagnostics enabled, we skip
clearing its diagnostics.

## Testing

Added two new integration tests in
`crates/project/tests/integration/project_tests.rs`:
1.
`test_diagnostic_summaries_cleared_on_buffer_close_without_workspace_diagnostics`:
Verifies that diagnostics are cleared on buffer close when workspace
diagnostics is disabled.
2.
`test_diagnostic_summaries_retained_on_buffer_close_with_workspace_diagnostics`:
Verifies that diagnostics are retained when workspace diagnostics are
enabled. (This test fails on the current `main` branch).

I have also verified this functionality locally. Both local and remote
development environments work as expected.

Ibrahim Khan 2243c13b9b project: Fix content swap when an LSP rename also renames the file (#59104)
A "rename symbol" whose workspace edit also renames the file (a
`TextDocumentEdit` followed by a `RenameFile` resource operation) only
applied the text edit to the in-memory buffer. The on-disk file still
held the pre-edit content, so the blind `fs.rename` moved stale bytes to
the new path while the edited buffer was stranded at the old path,
swapping the two files' contents.

This persists a dirty buffer for the rename source before renaming, so
the new file receives the edited content and the now-clean buffer can't
be saved back to the old path.

c31b2b0dc7 Git partially staged changes (#46541)
This PR explores the addition of a new feature and UI to improve
visibility into partially staged commits.

Currently, the Git panel shows tracked and untracked changes, but it
does not clearly distinguish between staged and unstaged changes.

As a result, it’s difficult to quickly see which changes are not staged
in the current UI. Both staged and unstaged changes are combined into
the `Uncommitted Changes` multibuffer. This developer experience differs
from other editors, most notably VS Code; which presents separate Staged
Changes and Changes lists.

### Staged and unstaged diffs in multibuffers

This PR introduces an alternative UI for unstaged changes that aligns
with the overall Zed experience. Instead of showing changes on a
per-file basis, staged and unstaged diffs are each displayed in their
own multibuffers, similar to how `Uncommitted Changes` currently works.

For example the following screenshot shows the current `Uncommitted
Changes` on the left, the `Staged Changes` in the middle and the
`Unstaged Changes` buffer on the right for comparison

<img width="1408" height="859"
src="https://github.com/user-attachments/assets/aa709f7a-041d-4cb1-95d6-84c0f5fff688"
/>

### Indicators/interactions

The new multibuffers can be opened in two ways:

1. Via a new `U` chip, which appears when a file has unstaged changes
2. Via new menu options

(See screenshots below for both interaction paths.)


<table>
  <tr>
    <td style="text-align: center; vertical-align: top;">
      <p>via the chip</p>
      <img
        height="400"

src="https://github.com/user-attachments/assets/3ef69f02-b787-499c-959a-25f50b3728e8"
        alt="Via the chip"
      />
    </td>
    <td style="text-align: center; vertical-align: top;">
      <p>via the menu</p>
      <img
        height="400"

src="https://github.com/user-attachments/assets/f5be8b6d-ccdc-4420-bd29-75570b558016"
        alt="Via the menu"
      />
    </td>
  </tr>
</table>

### Design goals
- minimally intrusive UI changes (small new badge and menu items)
- adhere by Zed'ism (use multibuffer where possible)
- avoid disabling any current interactions (Uncommitted Changes ui is
unchanged)
- avoid introducing an app level view mode (no new settings needed)

### Experience goals
- make it easy to see what changes are not staged
- make it easy to see that a file has unstaged changes (avoid developers
accidently leaving out changes in a commit; a personal issue that I have
when using Zed)
- elegantly handle large file's unstaged changes (follows the same
collapse and expanding seen in `Uncommitted Changes`)

### How to try

- Clone the repo and run `cargo run`
- Make a change to a file and stage it
- Make another change to the file (the `U` indicator will appear)
- Click the `U` to see the unstaged view

### Open questions/rough edges
- [ ] determine if this user experience is useful for others
- [ ] ensure all interactions work as expected (response to all update
cases)

In general I'm really interested in hearing the community's feedback
about this interface, more than happy to make any changes or explore a
different solution!

Anant GoelandAnthony Eid ea87b05794 Fix worktree grouping for bare checkouts (#59968)
Summary

- Track whether a worktree root is itself a linked Git worktree.
- Use that metadata when computing project group keys so bare checkout
worktrees group under the repository identity path.
- Propagate the metadata through remote worktree protocols and add
local/remote regression coverage.

Background

Bare checkout layouts can place linked worktrees under the repository
identity directory, e.g. `/monty/.bare` with worktrees like
`/monty/feature-a`. We were treating those linked worktree paths as
separate project identities, which caused the sidebar to move agent
threads under the active worktree instead of the shared repository
group.
We also exclude adding this to collab intentionally, we can open a
different PR for that if we need to.

Closes #59910
Closes AI-431

Test Plan

- `cargo fmt --package project --package worktree --package
remote_server --package workspace --package collab --package proto`
- `git --no-pager diff --check`
- `cargo test -p project test_project_group_key -- --nocapture`
- `cargo test -p remote_server test_remote_root_repo_common_dir --
--nocapture`
- `cargo test -p worktree remote_worktree -- --nocapture`

Artem KalytiukandClaude Opus 4.8 2a93ca53fd Handle dynamic registration of semantic tokens capability (#60015)
In C# files nothing gets semantic highlighting — class fields and other
identifiers are colored by tree-sitter only, so a private field looks
the same as a plain local variable.

The reason: Roslyn (the C# language server) doesn't declare
`semanticTokensProvider` statically in its `initialize` response. It
registers it **dynamically** (`client/registerCapability`), and only
when the client advertises
`textDocument.semanticTokens.dynamicRegistration = true`. Zed advertised
`false` and didn't handle such a registration, so Roslyn never offered
semantic tokens at all. (rust-analyzer/gopls are unaffected — they
declare the capability statically.)

This is the first of two PRs. This one makes Roslyn actually **send**
semantic tokens. The companion PR (#60027) maps Roslyn's C#-specific
token types to theme styles — without it the tokens arrive but most are
dropped, since their types aren't in Zed's default rules.

## Solution

- Advertise `textDocument.semanticTokens.dynamicRegistration = true`.
- Handle the `textDocument/semanticTokens` registration and
unregistration so the capability is stored, following the existing arms
for `documentLink`, diagnostics, etc.

## Testing

- Added a test that dynamically registers and unregisters
`textDocument/semanticTokens` and checks the stored capability appears
and is cleared.
- Verified manually against Roslyn on a C# project: Zed now sends
`textDocument/semanticTokens/full` and gets tokens back; before this
change there was no semantic-token traffic at all.

Closes #57888 

Commit `c19cc4c51e0f64eec42168943050f2deeccaa076` introduced the bug on
#50412 . This change modified the `remove_path` function to also remove
the path from the watcher:


https://github.com/zed-industries/zed/blob/f0341c96a17630e5dfb441701441945dbb2a605a/crates/worktree/src/worktree.rs#L3218-L3220

And when a user modified the global setting and doesn't include `.git`
in it, like:

```jsonc
// ~/.config/zed/settings.json
{
  "file_scan_exclusions": ["foo"]
}
```

But then includes it on their local project settings: 

```jsonc
// ~/my/local/project/.zed/settings.json
{
  "file_scan_exclusions": ["**/.git"]
}
```

It causes zed to stop watching for changes on `.git` 

Release Notes:

- Fixed bug where zed stopped watching change on `.git` directory if it
was added to the project local `file_scan_exclusions`

3df0812498 Refactor BufferDiff to allow multiple diffs to share the same base text buffer (#58266)
This PR changes how base texts are managed by the `buffer_diff` crate,
to enable keeping two diff entities alive that share the same base text
buffer entity. Previously, each diff owned its own base text buffer and
edited it when calling `BufferDiff::set_snapshot`, so the only way to
reuse the same base text between two diffs was to have two independent
buffers for it, which is pretty inefficient.

After this PR, each diff still has a base text buffer, but
`set_snapshot` doesn't edit it. Instead, that responsibility moves into
the caller. For updating the base text buffer, this PR also introduces a
new pair of APIs, `Buffer::snapshot_with_edits` and
`Buffer::fast_forward`, which allow us to move the parsing of the new
base text into the background and then install the new syntax tree
synchronously on the foreground.

The git store uses the low-level APIs `set_snapshot` and `fast_forward`
directly, and manages the head text and index text buffers itself
(garbage-collecting them when they're no longer needed); this enables
adding an `open_staged_diff` API which returns a diff between the
managed index buffer and the managed head buffer (the latter is also
used for the uncommitted diff's base text). Other downstreams don't need
to reuse a base text buffer, and those have been migrated to use the
high-level `set_base_text` API, which now calls `set_snapshot` and
`fast_forward` internally, with a guard to prevent concurrent updates.

Another change worthy of note is that we now always diff the old base
text with the new base text to create `snapshot_with_edits`.

There are also some incidental bug fixes:
- Fixed an issue where a dangling weak unstaged diff could stick around
in the git store forever
- Restored the `IndexMatchesHead` optimization that had become
inoperative in the remote case
- Fixed a crash in the multibuffer due to the handling of
`BufferDiffEvent::LanguageChanged`, which could cause the multibuffer to
have transforms that were inconsistent with the diff base text.

Shuhei Kadowaki 3d9852ae04 lsp: Fix duplicate workspace/didChangeConfiguration notifications (#56853)
Editing the `lsp` section of `.zed/settings.json` caused two identical
`workspace/didChangeConfiguration` notifications to be sent to each
language server, e.g.:

    // Send:

{"jsonrpc":"2.0","method":"workspace/didChangeConfiguration","params":{"settings":{"jetls":{"code_lens":{"references":true},"completion":{"method_signature":{"prepend_inference_result":true}},"full_analysis":{"debounce":2},"inlay_hint":{"block_end":{"min_lines":25}}}}}}

    // Send:

{"jsonrpc":"2.0","method":"workspace/didChangeConfiguration","params":{"settings":{"jetls":{"code_lens":{"references":true},"completion":{"method_signature":{"prepend_inference_result":true}},"full_analysis":{"debounce":2},"inlay_hint":{"block_end":{"min_lines":25}}}}}}

`maintain_workspace_config` observed `SettingsStore` directly while
`on_settings_changed` also fed the same loop through
`request_workspace_config_refresh`, so every settings change drove the
refresh loop twice and sent two identical
`workspace/didChangeConfiguration` notifications to each language
server.

Drop the in-loop observer and drive the loop from
`external_refresh_requests` alone. Settings changes still arrive via
`on_settings_changed -> request_workspace_config_refresh`, and toolchain
activation continues to use the same channel.

Cole Miller bcfbf669bd git: Degrade gracefully when refreshing git state (#57292)
This PR changes the git store's `compute_snapshot`, which runs to update
state that depends on the contents of `.git`, to degrade gracefully when
fetching individual pieces of state fails. For example, when fetching
the list of branches fails, instead of returning early from the function
(leaving the previous git state snapshot in place with stale state), we
continue with an empty list of branches. This prevents failures of
individual git commands from making the entire git UI get stuck
indefinitely.

fddfc3fbee acp: Prevent registry loading from hanging indefinitely (#56108)
Helps #51567
Refs #54531

Summary:

- Add total timeouts for ACP Registry JSON fetches and icon fetches,
including response body reads.
- Download registry icons concurrently and keep icon failures non-fatal,
so a blocked icon CDN does not delay registry availability by one
timeout per agent.
- Surface the stored registry fetch error in the ACP Registry empty
state and add a retry action.

This addresses cases where the registry request, or one of the icon
requests, never finishes. It does not make blocked networks succeed, but
it prevents the UI from sitting on `Loading registry...` indefinitely
and gives the user something actionable instead.

Test plan:

- `git diff --check HEAD~1..HEAD`
- `cargo fmt --check --package project --package agent_ui`
- `cargo check -p project`
- `cargo check -p agent_ui`
- `cargo test -p project --features test-support registry_refresh_`

Release Notes:

- Fixed the ACP Registry getting stuck on loading when registry or icon
requests hang.

Max Brunsfeld caccc65b1e Improve bare repo support (#55153)
Fixes https://github.com/zed-industries/zed/issues/54830

This fixes a bugs where
* when there's no main worktree, we treated the first linked worktree as
main
* the titlebar and sidebar showed two different things when opening a
linked wortree directly

When there's no main worktree, our "project group key" will be the bare
repo path. For displaying this to the user, we try to present something
meaningful:
* If the bare repo is `foo.git`, we'll say "foo"
* If the bare repo is "bar/.bare", we'll "bar"

Release Notes:

- Fixed bugs in Zed's sidebar and titlebar when editing in git worktrees
created from bare repositories.

109c2238aa Fix freeze when binary content written to open empty file (#53074)
Opening an empty file then writing binary content to it on disk causes a
permanent freeze (not a crash — requires force kill).

`reload_impl` loads raw bytes via `load_bytes` and decodes with
`encoding_rs` but never checks if the content is binary. The existing
binary check in `decode_file_text` only runs on fresh opens, not
reloads. So binary content enters the buffer as lossy UTF-8.

Binary data has almost no newlines, producing a single enormous row. The
wrap map's sync fast path in `flush_edits` checks row count (< 100 rows)
but not line length, so it runs `wrap_line` on a multi-MB single line
synchronously on the main thread via `smol::block_on`. Font shaping
millions of non-ASCII replacement characters blocks the UI thread
indefinitely.

Two fixes, both one-condition guards:
- Null-byte check in `reload_impl` before decoding, same heuristic
(first 8000 bytes) used by `decode_file_text` on fresh opens. Binary
content never enters the buffer.
- Column-length guard (`MAX_SYNC_WRAP_COLUMNS = 10_000`) on the wrap map
sync fast path so absurdly long lines fall through to the async
background path. Defense in depth for any single-line content that's too
long to shape synchronously.

## Test plan
- [ ] Open an empty file in Zed, write binary content to it externally
(e.g. `cp /bin/ls /path/to/open-file`) — should show "Binary files are
not supported" instead of freezing
- [ ] Open a compressed file (zip, gz) that starts empty and gets filled
— same behavior
- [ ] Normal text file reload still works (no regression)
- [ ] Very long single-line text files (>10k columns) don't freeze the
editor

meloceneandSmit Barmase 2a6ee04013 Add line_ending setting to control line-ending normalization (#54356)
Closes #49581

Adds a `line_ending` language setting that controls how line endings are
handled for new files and during format/save:

- `detect` (default) — detects existing line endings; new files use the
platform default
- `prefer_lf` / `prefer_crlf` — sets LF or CRLF for new files and files
with no existing convention, while preserving existing files
- `enforce_lf` / `enforce_crlf` — normalizes all line endings to LF or
CRLF on every format/save

The setting can be configured globally, per-language, or via
`.editorconfig`'s `end_of_line` property (which maps to `enforce_lf` /
`enforce_crlf`).

Release Notes:

- Added `line_ending` setting to control how line endings are handled
for new files and normalized on save.
- Added support for `.editorconfig` `end_of_line` property to enforce
line endings.

Arthur Fournier 03414d8058 languages: Fix Python LSP workspace folder detection in uv workspaces (#53781)
Closes #47926

  ## Summary

When using a uv (or Poetry/PDM) workspace with multiple subprojects,
Python LSP servers (Pyright, Ruff, ty, etc.) are initialized with the
subproject directory as their workspace folder instead of the workspace
root. This happens because `PyprojectTomlManifestProvider::search()`
returns the first (innermost)
  `pyproject.toml` found walking up the directory tree.

  For example, in a uv workspace like:

  main-project/
  ├── pyproject.toml       # workspace root with [tool.uv.workspace]
  ├── uv.lock
  ├── packages/
  │   └── project-api/
  │       └── pyproject.toml   # subpackage
  └── projects/
      └── project-a/
          └── pyproject.toml   # subpackage

Opening a file in `packages/project-api/` would register
`packages/project-api/` as the LSP workspace folder instead of
`main-project/`.

  ## Approach

The fix uses lockfile existence as a heuristic to detect workspace
roots. The updated `search()` method walks all ancestors (similar to
`CargoManifestProvider`) and:

  - Tracks the **innermost** `pyproject.toml` as a fallback
- Tracks the **outermost** `pyproject.toml` that has a sibling lockfile
(`uv.lock`, `poetry.lock`, `pdm.lock`, or `Pipfile.lock`)
- Returns the outermost workspace root if found, otherwise falls back to
the innermost

This works within the existing `ManifestDelegate` interface (existence
checks only, no file content reading).

  | Scenario | Result |
  |---|---|
| uv workspace (root `pyproject.toml` + `uv.lock`) | Returns workspace
root |
| Poetry workspace (root `pyproject.toml` + `poetry.lock`) | Returns
workspace root |
| Simple project (single `pyproject.toml`, no lockfile) | Returns
project dir (unchanged) |
| Independent subprojects (no lockfile at any level) | Returns each
project's own dir (unchanged) |

Since the manifest provider is set at the Python **language** level,
this fix applies to all Python LSP servers (Pyright, Ruff, ty, etc.).

  ## Test plan

- [x] Added unit tests for `PyprojectTomlManifestProvider` covering all
scenarios above
- [x] Existing integration test
`test_running_multiple_instances_of_a_single_server_in_one_worktree`
passes (independent subprojects without lockfiles)
  - [x] `cargo check -p languages` compiles cleanly
- [x] Manual testing with a real uv workspace (Pyright and Ruff both
receive correct workspace root)

Release Notes:

- Fixed Python LSP servers (Pyright, Ruff, etc.) using the wrong
workspace folder in uv/Poetry/PDM workspaces with multiple subprojects.

Yara 🏳️‍⚧️andAustin Cummings 73126dcb81 editor: Introduce Bookmarks (#54174)
Adds basic bookmark functionality to the editor, allowing users to mark
lines and later navigate between them. This is an MVP and will later be
expanded with a picker, vim marks integration and syntax tree based
bookmark positions. In this MVP bookmarks shift under external edits.

# UI
## Adding/Removing bookmarks
To add a bookmark:
- run the toggle bookmark action 
- hold secondary and click in the gutter
- open the context menu by right clicking in the gutter and select add
bookmark To remove a bookmark:
- run the toggle bookmark action 
- click on the bookmarks icon in the gutter
- open the context menu by right clicking in the gutter and select
remove bookmark

remove all bookmarks with `workspace: clear bookmarks`


# Implementation
This mirrors the implementation of breakpoints. The rendering of the
gutter was refactored to make place for bookmark icons and buttons:
- Code was extracted to a `Gutter` struct
- Runnables, breakpoints and bookmarks are now collected ahead of
layouting. Just before layouting we remove the items that collide and do
not have priority.
- The `phantom_breakpoint` is replaced by a `gutter_hover_button`

## In depth phantom breakpoint discussion:
This was phantom_breakpoint. It worked as follows:
 - A fake breakpoint was added to the list of breakpoints.
- While rendering the breakpoints it a breakpoint turned out to be fake
it would get a different description and look.
- The breakpoint list was edited run_indicators ("play buttons")
rendering to removes the fake breakpoint if it collided.

This would not scale to more functionality. Now we only render
breakpoints, bookmarks and run indicators. Then we render a button if
there is not breakpoint, bookmark or run indicator already present. We
can do so since the rendering of such "gutter indicators" has been
refactored into two phases:
 - collect the items.
 - render them if no higher priority item collides.

This is far easier and more readable which enabled me to easily take the
phantom_breakpoint system and use it for placing bookmarks as well :)

Note: this was previously merged but it needed a better squashed commit
message. For the actual PR see: 51404. This reverts commit
7e523a2d2b.

- Added Bookmarks

Austin CummingsandYara 79473da756 editor: Bookmarks MVP (#51404)
Closes #4526

Adds basic bookmark functionality to the editor, allowing users to mark
lines and later navigate between them.

### What's new

**Toggling bookmarks**
Users can toggle a bookmark on the current line(s) via the `editor:
toggle bookmark` action. A bookmark icon appears in the gutter for each
bookmarked line.

**Navigation**
Two new actions, `editor: go to next bookmark` and `editor: go to
previous bookmark`, navigate between bookmarks in the current buffer,
wrapping around at the ends of the buffer.

**Viewing all bookmarks**
`editor: view bookmarks` opens all bookmarks across the project in a
multibuffer, similar to how references and diagnostics are surfaced.

**Clearing bookmarks**
`workspace: clear bookmarks` removes all bookmarks in the current
project.

**Persistence**
Bookmarks are persisted to the workspace database and restored when the
workspace is reopened. They are stored as `(path, row)` pairs and
resolved back to text anchors. Out of range or unresolvable bookmarks
are skipped with a logged warning.

**Gutter rendering**
Bookmark icons are rendered in the gutter using the existing gutter
button layout system, consistent with breakpoints. They are suppressed
on lines that already show a breakpoint or phantom breakpoint indicator.
A new `gutter.bookmarks` setting (defaulting to `true`) controls their
visibility.

### What's left

- [x] Lazily load buffers that have bookmarks
- [x] Clean up test boilerplate
- [ ] Assign default keybindings
- [ ] Compare line of saved bookmarks with current buffer (gray out the
"stale" bookmarks)

### What's next (and nice to haves)
- [ ] Resilience against external edits
- [ ] Save column position with the bookmark
- [ ] Bookmarks attached to syntactic structures?
- [ ] Labeled bookmarks?

---

Release Notes:

- Added bookmarks: toggle bookmarks on lines with `editor: toggle
bookmark`, navigate with `editor: go to next bookmark` / `editor: go to
previous bookmark`, view all bookmarks with `editor: view bookmarks`,
and clear with `workspace: clear bookmarks`. Bookmarks are shown in the
gutter and persisted across sessions.

Pratik KarkiandKirill Bulatov b6b2b63370 Gate Format Selections on whether the active formatter can actually format ranges (#53178)
## What Changed

- compute range-format support from formatter configuration and
language-server capabilities
- show `Format Selections` only when at least one selected buffer has a
range-capable formatter
- keep Prettier-supported range formatting available without depending
on LSP support
- hide the action for formatter modes that cannot honor selections, such
as external-command and code-action formatters
- keep the action handler safe by rechecking support and returning early
when range formatting is unavailable
- restrict capability checks to the servers actually registered for the
current buffer
- add regression coverage for supported, unsupported, and mixed-server
cases
- document when `Format Selections` is available in both action docs and
user docs


Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content is consistent with the [UI/UX
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Closes #25796

Release Notes:
- Improved `Format Selections` so it is only shown when the active
formatter supports range formatting.

Testing I did:

Here are the formatters I used:
<img width="829" height="434" alt="Screenshot_20260405_102047"
src="https://github.com/user-attachments/assets/cae4a238-277e-4188-873f-189e9f098699"
/>

Note: I've chosen three formatters:
1. Prettier, which supports range formatting

Cole Miller 652f1fa3b0 git: Fix a race that caused incorrect hunk staging information (#53929)
In `GitStore::open_diff_internal`, when opening a `DiffKind::Unstaged`
diff, we previously always overwrote the `unstaged_diff` field of
`BufferGitState`. This causes a bug in the following situation:

- We call `open_unstaged_diff`, and it hits an await point where it is
loading the index text
- While that task is suspended, we call `open_uncommitted_diff`. It
reaches `open_diff_internal` and sets
`buffer_git_state.uncommitted_diff` and
`buffer_git_state.unstaged_diff`. It also sets the secondary diff for
the uncommitted diff to be the unstaged diff that it just opened.
- The `open_unstaged_diff` task wakes up and enters
`open_diff_internal`. It creates a new entity for the unstaged diff and
overwrites `buffer_git_state.unstaged_diff` with it, but it doesn't
update the secondary diff of the uncommitted diff, which still has the
entity that was produced in the previous step.
- Now the uncommitted diff's secondary diff will never receive updates
from the `GitStore`, causing staging information to be incorrect.

The fix is for `open_diff_internal` to not overwrite an existing
unstaged diff.

Closes #50212

There are two unreasonable coupling account for this issue, the coupling
of `use_tree_sitter` with `languge_aware` in

https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/editor/src/element.rs#L3820-L3822
and the coupling of `language_aware` with `diagnostics` in
https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/language/src/buffer.rs#L3736-L3746

Because of these couplings, when the editor stops using Tree-sitter
highlighting when `"semantic_tokens"` set to `"full"`, it also
accidentally stops fetching diagnostic information. This is why error
and warning underlines disappear.

I’ve fixed this by adding a separate `use_tree_sitter` parameter to
`highlighted_chunks`. This way, we can keep `language_aware` true to get
the diagnostic data we need, but still decide whether or not to apply
Tree-sitter highlights. I chose to fix this at the `highlighted_chunks`
level because I’m worried that changing the logic in the deeper layers
of the DisplayMap or Buffer might have too many side effects that are
hard to predict. This approach feels like a safer way to solve the
problem.

Release Notes:

- Fixed a bug where diagnostic underlines disappeared when
"semantic_tokens" set to "full"

Anthony Eid 7748047051 git_graph: Refresh UI when stash/branch list has changed (#53094)
### Summary 

This PR fixes an issue where the git graph wouldn't refresh its state
correctly unless HEAD changed. Now repository emits events when the
branch list has changed, and invalidates the graph data cache when the
stash or branch list has changed.

I also renamed the event `Repository::BranchedChanged` to
`Repository::HeadChanged` as well.

DinoandYara c0f01c4278 Update futures to 0.3.32 (#52910)
As part of the work that is being developed for the Project Panel's Undo
& Redo system, in
https://github.com/zed-industries/zed/tree/5039-create-redo , we're
implementing an asynchronous task queue which simply receives a message
with the operation/change that is meant to be carried out, in order to
ensure these run in a sequential fashion.

While trying to use `futures_channel::mpsc::Receiver`, it was noted that
`recv` method was not available so this Pull Request updates the
`futures` crate to `0.3.32`, where it is available.

This version also deprecates `try_next` in favor of `try_recv` so this
Pull Request updates existing callers of `try_next` to use `try_recv`,
which was mostly updating the expected return type from
`Result<Option<T>>` to `Result<T>`.

2a15bf630d Require multibuffer excerpts to be ordered and nonoverlapping (#52364)
TODO:
- [x] merge main
- [x] nonshrinking `set_excerpts_for_path`
- [x] Test-drive potential problem areas in the app
- [x] prepare cloud side
- [x] test collaboration
- [ ] docstrings
- [ ] ???

## Context

### Background

Currently, a multibuffer consists of an arbitrary list of
anchor-delimited excerpts from individual buffers. Excerpt ranges for a
fixed buffer are permitted to overlap, and can appear in any order in
the multibuffer, possibly separated by excerpts from other buffers.
However, in practice all code that constructs multibuffers does so using
the APIs defined in the `path_key` submodule of the `multi_buffer` crate
(`set_excerpts_for_path` etc.) If you only use these APIs, the resulting
multibuffer will maintain the following invariants:

- All excerpts for the same buffer appear contiguously in the
multibuffer
- Excerpts for the same buffer cannot overlap
- Excerpts for the same buffer appear in order
- The placement of the excerpts for a specific buffer in the multibuffer
are determined by the `PathKey` passed to `set_excerpts_for_path`. There
is exactly one `PathKey` per buffer in the multibuffer

### Purpose of this PR

This PR changes the multibuffer so that the invariants maintained by the
`path_key` APIs *always* hold. It's no longer possible to construct a
multibuffer with overlapping excerpts, etc. The APIs that permitted
this, like `insert_excerpts_with_ids_after`, have been removed in favor
of the `path_key` suite.

The main upshot of this is that given a `text::Anchor` and a
multibuffer, it's possible to efficiently figure out the unique excerpt
that includes that anchor, if any:

```
impl MultiBufferSnapshot {
    fn buffer_anchor_to_anchor(&self, anchor: text::Anchor) -> Option<multi_buffer::Anchor>;
}
```

And in the other direction, given a `multi_buffer::Anchor`, we can look
at its `text::Anchor` to locate the excerpt that contains it. That means
we don't need an `ExcerptId` to create or resolve
`multi_buffer::Anchor`, and in fact we can delete `ExcerptId` entirely,
so that excerpts no longer have any identity outside their
`Range<text::Anchor>`.

There are a large number of changes to `editor` and other downstream
crates as a result of removing `ExcerptId` and multibuffer APIs that
assumed it.

### Other changes

There are some other improvements that are not immediate consequences of
that big change, but helped make it smoother. Notably:

- The `buffer_id` field of `text::Anchor` is no longer optional.
`text::Anchor::{MIN, MAX}` have been removed in favor of
`min_for_buffer`, etc.
- `multi_buffer::Anchor` is now a three-variant enum (inlined slightly):

```
enum Anchor {
    Min,
    Excerpt {
        text_anchor: text::Anchor,
        path_key_index: PathKeyIndex,
        diff_base_anchor: Option<text::Anchor>,
    },
    Max,
}
```

That means it's no longer possible to unconditionally access the
`text_anchor` field, which is good because most of the places that were
doing that were buggy for min/max! Instead, we have a new API that
correctly resolves min/max to the start of the first excerpt or the end
of the last excerpt:


```
impl MultiBufferSnapshot {
    fn anchor_to_buffer_anchor(&self, anchor: multi_buffer::Anchor) -> Option<text::Anchor>;
}
```
- `MultiBufferExcerpt` has been removed in favor of a new
`map_excerpt_ranges` API directly on `MultiBufferSnapshot`.

Richard Feldman 7cf26f4046 Fix submodules being incorrectly classified as linked worktrees (#52507)
For submodules, `common_dir_abs_path` equals `repository_dir_abs_path`
(since submodules don't have a `commondir` file). The previous code
passed this path to `original_repo_path_from_common_dir`
unconditionally, which returned the `.git/modules/<name>` path as the
`original_repo_abs_path` — causing `linked_worktree_path()` to return a
false positive for submodules.

Now we detect linked worktrees by checking whether `common_dir` differs
from `repository_dir` (only true for actual linked worktrees that have a
`commondir` file). For normal repos and submodules,
`original_repo_abs_path` is simply `work_directory_abs_path`.

Also fixes the misleading doc comment on `common_dir_abs_path` in
`LocalRepositoryEntry` and adds test assertions for
`original_repo_abs_path` and `linked_worktree_path()` on both worktrees
and submodules.

Closes AI-102

Release Notes:

- Fixed git submodules being incorrectly classified as linked worktrees,
which could cause issues with worktree-related operations.

3ce0cd11ec Extract language_core and grammars crates from language (#52238)
This extracts a `language_core` crate from the existing `language`
crate, and creates a `grammars` data crate. The goal is to separate
tree-sitter grammar infrastructure, language configuration, and LSP
adapter types from the heavier buffer/editor integration layer in
`language`.

## Motivation

The `language` crate pulls in `text`, `theme`, `settings`, `rpc`,
`task`, `fs`, `clock`, `sum_tree`, and `fuzzy` — all of which are needed
for buffer integration (`Buffer`, `SyntaxMap`, `Outline`,
`DiagnosticSet`) but not for grammar parsing or language configuration.
Extracting the core types lets downstream consumers depend on
`language_core` without pulling in the full integration stack.

## Dependency graph after extraction

```
language_core   ← gpui, lsp, tree-sitter, util, collections
grammars        ← language_core, rust_embed, tree-sitter-{rust,python,...}
language        ← language_core, text, theme, settings, rpc, task, fs, ...
languages       ← language, grammars
```

## What moved to `language_core`

- `Grammar`, `GrammarId`, and all query config/builder types
- `LanguageConfig`, `LanguageMatcher`, bracket/comment/indent config
types
- `HighlightMap`, `HighlightId` (theme-dependent free functions
`highlight_style` and `highlight_name` stay in `language`)
- `LanguageName`, `LanguageId`
- `LanguageQueries`, `QUERY_FILENAME_PREFIXES`
- `CodeLabel`, `CodeLabelBuilder`, `Symbol`
- `Diagnostic`, `DiagnosticSourceKind`
- `Toolchain`, `ToolchainScope`, `ToolchainList`, `ToolchainMetadata`
- `ManifestName`
- `SoftWrap`
- LSP data types: `BinaryStatus`, `ServerHealth`,
`LanguageServerStatusUpdate`, `PromptResponseContext`, `ToLspPosition`

## What stays in `language`

- `Buffer`, `BufferSnapshot`, `SyntaxMap`, `Outline`, `DiagnosticSet`,
`LanguageScope`
- `LspAdapter`, `CachedLspAdapter`, `LspAdapterDelegate` (reference
`Arc<Language>` and `WorktreeId`)
- `ToolchainLister`, `LanguageToolchainStore` (reference `task` and
`settings` types)
- `ManifestQuery`, `ManifestProvider`, `ManifestDelegate` (reference
`WorktreeId`)
- Parser/query cursor pools, `PLAIN_TEXT`, point conversion functions

## What the `grammars` crate provides

- Embedded `.scm` query files and `config.toml` files for all built-in
languages (via `rust_embed`)
- `load_queries(name)`, `load_config(name)`,
`load_config_for_feature(name, grammars_loaded)`, and `get_file(path)`
functions
- `native_grammars()` for tree-sitter grammar registration (behind
`load-grammars` feature)

## Pre-cleanup (also in this PR)

- Removed unused `Option<&Buffer>` from
`LspAdapter::process_diagnostics`
- Removed unused `&App` from `LspAdapter::retain_old_diagnostic`
- Removed `fs: &dyn Fs` from `ToolchainLister` trait methods
(`PythonToolchainProvider` captures `fs` at construction time instead)
- Moved `Diagnostic`/`DiagnosticSourceKind` out of `buffer.rs` into
their own module

## Backward compatibility

The `language` crate re-exports everything from `language_core`, so
existing `use language::Grammar` (etc.) continues to work unchanged. The
only downstream change required is importing `CodeLabelExt` where
`.fallback_for_completion()` is called on the now-foreign `CodeLabel`
type.

- N/A

58fec75396 Add vim/emacs modeline support (#49267)
Many editors such as vim and emacs support "modelines", a comment at the
beginning of the file that allows the file type to be explicitly
specified along with per-file specific settings

- The amount of configurations, style and settings mapping cannot be
handled in one go, so this opens up a lot of potential improvements.
- I left out the possiblity to have "zed" specific modelines for now,
but this could be potentially interesting.
- Mapping the mode or filetype to zed language names isn't obvious
either. We may want to make it configurable.

This is my first contribution to zed, be kind. I struggled a bit to find
the right place to add those settings. I use a similar approach as done
with editorconfig (merge_with_editorconfig). There might be better ways.

Closes #4762

Release Notes:

- Add basic emacs/vim modeline support.

Supersedes #41899, changes:
- limit reading to the first and last 1kb
- add documentation
- more variables handled
- add Arc around ModelineSettings to avoid extra cloning
- changed the way mode -> language mapping is done, thanks to
`modeline_aliases` language config
- drop vim ex: support
- made "Local Variables:" handling a separate commit, so we can drop it
easily
- various code style improvements

372ce88725 agent: Wait until linked git worktree state is loaded (#51395)
### Context 

This fixes a bug where the sidebar would show a newly created git
worktree thread as its own project while the recently created workspace
is loading its git state. The fix is adding project APIs to await the
initial worktree store scan and then each git repo initial snapshot;
then awaiting on them before adding the new workspace to the
multi-workspace.

### Architecture:

I added the `Worktree::Remote::wait_for_snapshot` API to
`Worktree::Local` to enable `WorktreeStore` to await for both remote and
local projects until there's an initial scan. The `WorktreeStore` uses
the watcher pattern so it can update the initial scan state whenever
visible worktrees are added or removed from the store.

Before you mark this PR as ready for review, make sure that you have:
- [x] Added solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
