73d935330e Integrate scheduler crate into GPUI (#44810)
## Motivation

This PR unifies the async execution infrastructure between GPUI and
other components that depend on the `scheduler` crate (such as our cloud
codebase). By having a scheduler that lives independently of GPUI, we
can enable deterministic testing across the entire stack - testing GPUI
applications alongside cloud services with a single, unified scheduler.

## Summary

This PR completes the integration of the `scheduler` crate into GPUI,
unifying async execution and enabling deterministic testing of GPUI
combined with other components that depend on the scheduler crate.

## Key Changes

### Scheduler Integration (Phases 1-5, previously completed)
- `TestDispatcher` now delegates to `TestScheduler` for timing, clock,
RNG, and task scheduling
- `PlatformScheduler` implements the `Scheduler` trait for production
use
- GPUI executors wrap scheduler executors, selecting `TestScheduler` or
`PlatformScheduler` based on environment
- Unified blocking logic via `Scheduler::block()`

### Dead Code Cleanup
- Deleted orphaned `crates/gpui/src/platform/platform_scheduler.rs`
(older incompatible version)

## Intentional Removals

### `spawn_labeled` and `deprioritize` removed
The `TaskLabel` system (`spawn_labeled`, `deprioritize`) was removed
during this integration. It was only used in a few places for test
ordering control.

cc @maxbrunsfeld @as-cii - The new priority-weighted scheduling in
`TestScheduler` provides similar functionality through
`Priority::High/Medium/Low`. If `deprioritize` is important for specific
test scenarios, we could add it back to the scheduler crate. Let me know
if this is blocking anything.

### `start_waiting` / `finish_waiting` debug methods removed
Replaced by `TracingWaker` in `TestScheduler` - run tests with
`PENDING_TRACES=1` to see backtraces of pending futures when parking is
forbidden.

### Realtime Priority removed
The realtime priority feature was unused in the codebase. I'd prefer to
reintroduce it when we have an actual use case, as the implementation
(bounded channel with capacity 1) could potentially block the main
thread. Having a real use case will help us validate the design.

## Testing
- All GPUI tests pass
- All scheduler tests pass
- Clippy clean

## Architecture

Lukas Wirth ccce05d25c language: Fix reparse timeout not actually working (#45347)
We use `block_with_timeout` to give the reparse task a millisecond to
complete, and if it takes longer we put the work off to the background.
The reason for this is that we want tree-sitter based features to feel
snappy.
The reparse task is non-cooperative though, it has no yield points,
giving us no place to actually check for our timeout, meaning we will
always drive it to completion and block for the entire duration.
This kicks out the `block_with_timeout` in favor of using the treesitter
progress callback to handle timeouts instead.

Release Notes:

- Improved responsiveness with very language language files on edits

Marco Mihai CondracheandLukas Wirth ce99e7ef26 editor: Fix the merging of adjacent selection edits (#45363)
Closes #45046

The root of the issue is anchor resolution. When we apply adjacent
edits, they get merged into a single edit. In the scenario described in
the issue, this is what happens:

1. We create an anchor at the end of each selection (bias::right) on the
snapshot before the edits.
2. We collect the edits and apply them to the buffer.
3. Since the edits are adjacent (>=), the buffer merges them into a
single edit.
4. As a result, we apply one edit to the text buffer, creating a single
visible fragment with length = 3.
5. The buffer ends up with fragments like: [F(len = 3, visible = true),
F(len = 1, visible = false), ...]
6. After the edits, we resolve the previously created anchors to produce
zero-width selections (cursors).
7. All anchors resolve into deleted fragments, so their resolved offset
equals the cumulative visible offset, which is 3.
8. We now have 3 cursors with identical coordinates (0;3).
9. These cursors get merged into a single cursor.

I tried several approaches, but they either felt wrong or didn’t work.
In particular, I tried adjusting anchor resolution using the delta
stored in handle_input, but this doesn’t help because selections are
merged immediately after anchor resolution.

The only workable solution I found is to avoid anchors entirely for the
adjacent-edit case. Instead, we can compute the final cursor positions
directly from the edits and create the selections based on that
information.

Release Notes:

- Fixed an issue where adjacent selection insert would merge cursors

Lukas WirthandDanilo Leal dba13522d6 worktree: Implement read_only_files worktree setting (#44376)
This mimics VSCode's `files.readonlyExclude` setting, to allow setting
specific path matches as readonly locations like lockfiles and generated
sources etc.

Also renders a lock icon to the right side of the path names for
readonly files now.
This does a couple more things for completion sake:
- Tabs of readonly buffers now render a file lock icon
- Multibuffer buffer headers now render a file lock icon if the excerpts
buffer is readonly
- ReadWrite multibuffers now no longer allow edits to read only buffers
contained within

Release Notes:

- Added `read_only_files` setting to allow specifying glob patterns of
files that should not be editable by default

12dbbdd1d3 git: Fix bug where opening a git blob from historic commit view could fail (#44226)
The failure would happen if the current version of the file was open as
an editor. This happened because the git blob and current version of the
buffer would have the same `ProjectPath`.

The fix was adding a new `DiskState::Historic` variant to represent
buffers that are past versions of a file (usually a snapshot from
version control). Historic buffers don't return a `ProjectPath` because
the file isn't real, thus there isn't and shouldn't be a `ProjectPath`
to it. (At least with the current way we represent a project path)

I also change the display name to use the local OS's path style instead
of being hardcoded to Posix, and cleaned up some code too.

Ichimura Tomoo 1bc3fa8154 Correct UTF-16 saving and add heuristic encoding detection (#45243)
This commit fixes an issue where saving UTF-16 files resulted in UTF-8
bytes due to `encoding_rs` default behavior. It also introduces a
heuristic to detect BOM-less UTF-16 and binary files.

Changes:
- Manually implement UTF-16LE/BE encoding during file save to avoid
implicit UTF-8 conversion.
- Add `analyze_byte_content` to guess UTF-16LE/BE or Binary based on
null byte distribution.
- Prevent loading binary files as text by returning an error when binary
content is detected.

Special thanks to @CrazyboyQCD for pointing out the `encoding_rs`
behavior and providing the fix, and to @ConradIrwin for the suggestion
on the detection heuristic.

Closes #14654

Release Notes:

- (nightly only) Fixed an issue where saving files with UTF-16 encoding
incorrectly wrote them as UTF-8. Also improved detection for binary
files and BOM-less UTF-16.

81463223d5 Support opening and saving files with legacy encodings (#44819)
## Summary

Addresses #16965

This PR adds support for **opening and saving** files with legacy
encodings (non-UTF-8).
Previously, Zed failed to open files encoded in Shift-JIS, EUC-JP, Big5,
etc., displaying a "Could not open file" error screen. This PR
implements automatic encoding detection upon opening and ensures the
original encoding is preserved when saving.

## Implementation Details

1.  **Worktree (Loading)**:
* Updated `load_file` to use `chardetng` for automatic encoding
detection.
* Files are decoded to UTF-8 internal strings for editing, while
preserving the detected `Encoding` metadata.
2.  **Language / Buffer**:
* Added an `encoding` field to the `Buffer` struct to store the detected
encoding.
3.  **Worktree (Saving)**:
    * Updated `write_file` to accept the stored encoding.
    * **Performance Optimization**:
* **UTF-8 Path**: Uses the existing optimized `fs.save` (streaming
chunks directly from Rope), ensuring no performance regression for the
vast majority of files.
* **Legacy Encoding Path**: Implemented a fallback that converts the
Rope to a contiguous `String/Bytes` in memory, re-encodes it to the
target format (e.g., Shift-JIS), and writes it to disk.
* *Note*: This fallback involves memory allocation, but it is necessary
to support legacy encodings without refactoring the `fs` crate's
streaming interfaces.

## Changes

- `crates/worktree`:
    - Add dependencies: `encoding_rs`, `chardetng`.
    - Update `load_file` to detect encoding and decode content.
    - Update `write_file` to handle re-encoding on save.
- `crates/language`: Add `encoding` field and accessors to `Buffer`.
- `crates/project`: Pass encoding information between Worktree and
Buffer.
- `crates/vim`: Update `:w` command to use the new `write_file`
signature.

## Verification

I validated this manually using a Rust script to generate test files
with various encodings.

**Results:**

* ✅ **Success (Opened & Saved correctly):**
    * **Japanese:** `Shift-JIS` (CP932), `EUC-JP`, `ISO-2022-JP`
    * **Chinese:** `Big5` (Traditional), `GBK/GB2312` (Simplified)
* **Western/Unicode:** `Windows-1252` (CP1252), `UTF-16LE`, `UTF-16BE`
* ⚠️ **limitations (Detection accuracy):**
* Some specific encodings like `KOI8-R` or generic `Latin1` (ISO-8859-1)
may partially display replacement characters (`?`) depending on the file
content length. This is a known limitation of the heuristic detection
library (`chardetng`) rather than the saving logic.


Release Notes:

- Added support for opening and saving files with legacy encodings
(Shift-JIS, Big5, etc.)

a51e975b81 Improve support for multiple registrations of textDocument/diagnostic (#43703)
Closes https://github.com/zed-industries/zed/issues/41935

The registration ID responsible for generating each diagnostic is now
tracked. This allows us to replace only the diagnostics from the same
registration ID when a pull diagnostics report is applied.

Additionally, various deficiencies in our support for pull diagnostics
have been fixed:
- Document pulls are issued for all open buffers, not just the edited
one. A shorter debounce is used for the edited buffer. Workspace
diagnostics are also now ignored for open buffers.
- Tracking of `lastResultId` is improved.
- Stored pull diagnostics are discarded when the corresponding buffer is
closed.

Release Notes:

- Improved compatibility with language servers that use the "pull
diagnostics" feature of Language Server Protocol.

Oleksiy Syvokon 99d7b2fa1d zeta2: Compute diff-aware chrF metric (#43485)
Zeta evals now include a character n-gram metric adapted for multi-edit diffs (“delta chrF”). It works as follows:

1. Reconstruct the original, golden (expected), and actual texts from unified diffs.
   - "original": the text before any edits
   - "golden": the text after applying the expected edits
   - "actual": the text after applying the actual edits

2. Compute n-gram count deltas between original→golden and original→actual.
   - n-grams are computed as in chrF (max n=6, whitespace ignored).

3. Compare these deltas to assess how well the actual edits match the expected edits.
   - As in standard chrF, classify n-grams as true positives, false positives, and false negatives, and report the F-beta score with beta=2.

Kirill Bulatov 54309f4a48 Account for greedy tree-sitter bracket matches (#43607)
Current approach is to colorize brackets based on their depth, which was
broken for markdown:

<img width="388" height="50" alt="image"
src="https://github.com/user-attachments/assets/bd8b6c2f-5a26-4d6b-a301-88675bf05920"
/>

Markdown grammar, for bracket queries
https://github.com/zed-industries/zed/blob/00e93bfa113a3daed6e4a97a7244ad04d58453ee/crates/languages/src/markdown/brackets.scm#L1-L8

and markdown document `[LLM-powered features](./ai/overview.md), [bring
and configure your own API
keys](./ai/llm-providers.md#use-your-own-keys)`, matches first bracket
(offset 0) with two different ones:

* `[LLM-powered features]`

* `[LLM-powered features](./ai/overview.md), [bring and configure your
own API keys]`

which mix and add different color markers.

Now, in case multiple pairs exist for the same first bracket, Zed will
only colorize the shortest one:
<img width="373" height="33" alt="image"
src="https://github.com/user-attachments/assets/04b3f7af-8927-4a8b-8f52-de8b5bb063ac"

9122dd2d70 Combine zeta and zeta2 edit prediction providers (#43284)
We've realized that a lot of the logic within an
`EditPredictionProvider` is not specific to a particular edit prediction
model / service. Rather, it is just the generic state management
required to perform edit predictions at all in Zed. We want to move to a
setup where there's one "built-in" edit prediction provider in Zed,
which can be pointed at different edit prediction models. The only logic
that is different for different models is how we construct the prompt,
send the request, and parse the output.

This PR also changes the behavior of the staff-only `zeta2` feature flag
so that in only gates your *ability* to use Zeta2, but you can still use
your local settings file to choose between different edit prediction
models/services: zeta1, zeta2, and sweep.

This PR also makes zeta1's outcome reporting and prediction-rating
features work with all prediction models, not just zeta1.

To do:
* [x] remove duplicated logic around sending cloud requests between
zeta1 and zeta2
* [x] port the outcome reporting logic from zeta to zeta2.
* [x] get the "rate completions" modal working with all EP models
   * [x] display edit prediction diff
   * [x] show edit history events
* [x] remove the original `zeta` crate.

7e341bcf94 Support bracket colorization (rainbow brackets) (#43172)
Deals with https://github.com/zed-industries/zed/issues/5259

Highlights brackets with different colors based on their depth.
Uses existing tree-sitter queries from brackets.scm to find brackets,
uses theme's accents to color them.


https://github.com/user-attachments/assets/cc5f3aba-22fa-446d-9af7-ba6e772029da

1. Adds `colorize_brackets` language setting that allows, per language
or globally for all languages, to configure whether Zed should color the
brackets for a particular language.

Disabled for all languages by default.

2. Any given language can opt-out a certain bracket pair by amending the
brackets.scm like `("\"" @open "\"" @close) ` -> `(("\"" @open "\""
@close) (#set! rainbow.exclude))`

3. Brackets are using colors from theme accents, which can be overridden
as

```jsonc

Lukas Wirth c98b2d6944 multi_buffer: Typed MultiBufferOffset (#42707)
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.

This PR also uncovered two minor bugs due to that.

Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

c241eadbc3 zeta2: Targeted retrieval search (#42240)
Since we removed the filtering step during context gathering, we want
the model to perform more targeted searches. This PR tweaks search tool
schema allowing the model to search within syntax nodes such as `impl`
blocks or methods.

This is what the query schema looks like now:

```rust
/// Search for relevant code by path, syntax hierarchy, and content.
#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
pub struct SearchToolQuery {
    /// 1. A glob pattern to match file paths in the codebase to search in.
    pub glob: String,
    /// 2. Regular expressions to match syntax nodes **by their first line** and hierarchy.
    ///
    /// Subsequent regexes match nodes within the full content of the nodes matched by the previous regexes.
    ///
    /// Example: Searching for a `User` class
    ///     ["class\s+User"]
    ///
    /// Example: Searching for a `get_full_name` method under a `User` class
    ///     ["class\s+User", "def\sget_full_name"]
    ///
    /// Skip this field to match on content alone.
    #[schemars(length(max = 3))]
    #[serde(default)]
    pub syntax_node: Vec<String>,
    /// 3. An optional regular expression to match the final content that should appear in the results.
    ///
    /// - Content will be matched within all lines of the matched syntax nodes.
    /// - If syntax node regexes are provided, this field can be skipped to include as much of the node itself as possible.
    /// - If no syntax node regexes are provided, the content will be matched within the entire file.
    pub content: Option<String>,
}
```

We'll need to keep refining this, but the core implementation is ready.

Vitaly Slobodin cd87307289 language: Fix language detection for injected syntax layers (#41111)
Closes #40632

**TL;DR:** The `wrap selections in tag` action was unavailable in ERB
files, even when the cursor was positioned in HTML content (outside of
Ruby code blocks). This happened because `syntax_layer_at()` incorrectly
returned the Ruby language for positions that were actually in HTML.
**NOTE:** I am not familiar with that part of Zed so it could be that
the fix here is completely incorrect.

Previously, `syntax_layer_at` incorrectly reported injected languages
(e.g., Ruby in ERB files) even when the cursor was in the base language
content (HTML). This broke actions like `wrap selections in tag` that
depend on language-specific configuration.

The issue had two parts:
1. Missing start boundary check: The filter only checked if a layer's
end was after the cursor (`end_byte() > offset`), not if it started
before, causing layers outside the cursor position to be included. See
the `BEFORE` video: when I click on the HTML part it reports `Ruby`
language instead of `HTML`.
2. Wrong boundary reference for injections: For injected layers with
`included_sub_ranges` (like Ruby code blocks in ERB), checking the root
node boundaries returned the entire file range instead of the actual
injection ranges.

This fix:
- Adds the containment check using half-open range semantics [start,
end) for root node boundaries. That ensures proper reporting of the
detected language when a cursor (`|`) is located right after the
injection:

   ```
   <body>
    <%= yield %>|
  </body>
   ```

- Checks `included_sub_ranges` for injected layers to determine if the
cursor is actually within an injection
- Falls back to root node boundaries for base layers without sub-ranges.
This is the original behavior.

Fixes ERB language support where actions should be available based on
the cursor's actual language context. I think that also applies to some
other template languages like HEEX (Phoenix) and `*.pug`. On short
videos below you can see how I navigate through the ERB template and the
terminal on the right outputs the detected language if you apply the
following patch:

Lukas Wirth ac3b232dda Reduce amount of foreground tasks spawned on multibuffer/editor updates (#41479)
When doing a project wide search in zed on windows for `hang`, zed
starts to freeze for a couple seconds ultimately starting to error with
`Not enough quota is available to process this command.` when
dispatching windows messages. The cause for this is that we simply
overload the windows message pump due to the sheer amount of foreground
tasks we spawn when we populate the project search.

This PR is an attempt at reducing this.

Conrad Irwin e4f90b5da2 Fix race-condition in autosave (#39409)
This removes a long-standing thing we've done, which is send a `DidSave`
notification to the language server for the clean parts of a
multi-buffer. However, it seems like the intent of that notification is
to tell the language server to reload the file from disk.

As we didn't actually write those files to disk, it seems clearer to not
send this notification; and just remove this whole code-path.

- Fixed a race where autosave in a multibuffer could cause unsaved
buffers to appear saved

Cole Miller d83d7d35cb windows: Fix inconsistent separators in buffer headers and breadcrumbs (#38898)
Make `resolve_full_path` use the appropriate separators, and return a
`String`.

As part of fixing the fallout from that type change, this also fixes a
bunch of places in the agent code that were using `std::path::Path`
operations on paths that could be non-local, by changing them to operate
instead on strings and use the project's `PathStyle`.

This clears the way a bit for making `full_path` also return a string
instead of a `PathBuf`, but I've left that for a follow-up.

03f9cf4414 Represent relative paths using a dedicated, separator-agnostic type (#38744)
Closes https://github.com/zed-industries/zed/issues/38690
Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).
