This PR greatly improves our handling of remote threads in the sidebar.
One primary issue was that many parts of the sidebar were only looking
at a thread's path list and not its remote connection information. The
fix here is to use `ProjectGroupKey` more consistently throughout the
sidebar which also includes remote connection information.
The second major change is to extend the MultiWorkspace with the ability
to initiate the creation of remote workspaces when needed. This involved
refactoring a lot of our remote workspace creation paths to share a
single code path for better consistency.
Release Notes:
- (Preview only) Fixed remote project threads appearing as a separate
local project in the sidebar

We were incorrectly wrapping new terminal auth methods in double ssh
calls.
Only affected ACP beta users, but important for testing and stabilizing
the feature.
We moved the ssh wrapping to be only added in the acp process creation
where it was needed.

Closes#47907
Implements the four git checkpoint operations (`create`, `restore`,
`compare`, `diff`) that had been stubbed out for remote repositories,
and related test infrastructure.
Testing steps:
1. Open a project with a `.devcontainer` configuration and connect to
the Dev Container
2. Open an Agent thread and ask the agent to make a code change
3. After the agent completes, verify the "Restore from checkpoint"
button appears (previously missing in Dev Container sessions)
4. Click "Restore from checkpoint" and confirm the file reverts to its
prior state
Release Notes:
- Added support for git checkpoint operations in remote/Dev Container
sessions, restoring the "Restore from checkpoint" button in Agent
threads.

### Summary
This PR starts work on adding basic hook support in the `TaskStore`. To
enable users to setup tasks that are ran when the agent panel creates a
new git worktree to start a thread in. It also adds a new task variable
called `ZED_MAIN_GIT_WORKTREE` that's the absolute path to the main repo
that the newly created linked worktree is based off of.
### Follow Ups
- Get this hook working with the git worktree picker as well
- Make a more general approach to the hook system in `TaskStore`
- Add `ZED_PORT_{1..10}` task variables
- Migrate the task context creation code from `task_ui` to the basic
context provider

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.

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

Follow up on: https://github.com/zed-industries/zed/pull/49519
This PR reworks how Zed calculates diff num stats by moving the
calculation to the `RepositorySnapshot` layer, instead of the
`GitPanel`. This has a couple of benefits:
1. Snapshot recalculations are already set up to recompute on file
system changes and only update the affected files. This means that diff
stats don't need to manage their own subscription or states anymore like
they did in the original PR.
2. We're able to further separate the data layer from the UI. Before,
the git panel owned all the subscriptions and tasks that refreshed the
diff stat, now the repository does, which is more inline with the code
base.
3. Integration tests are cleaner because `FakeRepository` can handle all
the data and calculations of diff stat and make it accessible to more
tests in the codebase. Because a lot of tests wouldn't initialize the
git panel when they used the git repository.
4. This made implementing remote/collab support for this feature
streamline. Remote clients wouldn't get the same buffer events as local
clients, so they wouldn't know that the diff stat state has been updated
and invalidate their data.
5. File system changes that happened outside of Zed now trigger the diff
stat refresh because we're using the `RepositorySnapshot`.
I added some integration tests as well to make sure collab support is
working this time. Finally, adding the initial diff calculation to
`compute_snapshot` didn't affect performance for me when checking
against chromium's diff with HEAD~1000. So this should be a safe change
to make.
I decided to add diff stats on the status entry struct because it made
updating changed paths and the collab database much simpler than having
two separate SumTrees. Also whenever the UI got a file's status it would
check its diff stat as well, so this change makes that code more
streamlined as well.

We see a number of crashes in Sentry that appear to be crashes in
wasmtime.
This shouldn't happen, as wasmtime is designed to run untrusted code
"safely".
Looking into this, it seems likely that the problem is that we race with
wasmtime
when installing signal handlers. If wasmtime's handlers are installed
before ours,
then any signals that it intends to handle (like out of bounds memory
access) will
reach our handlers before its; which causes us to assume the app has
crashed.
This changes fixes our crash handler initialization to ensure we always
create
our signal handler first, and reverts a previous attempt to fix this
from #40883

Here's some backstory:
* on macOS, @cole-miller and I noticed that since roughly Oct 2025, due
to some changes to latest macOS Tahoe, for any spawned child process we
needed to reset Mach exception ports
(https://github.com/zed-industries/zed/issues/36754 +
https://github.com/RemiKalbe/zed/commit/6e8f2d2ebe5a93753625a3026aeb996de8cb436b)
* the changes in that PR achieve that via `pre_exec` hook on
`std::process::Command` which then abandons `posix_spawn` syscall for
`fork` + `execve` dance on macOS (we tracked it down in Rust's std
implementation)
* as it turns out, `fork` + `execve` is pretty expensive on macOS
(apparently way more so than on other OSes like Linux) and `fork` takes
a process-wide lock on the allocator which is bad
* however, since we wanna reset exception ports on the child, the only
official way supported by Rust's std is to use `pre_exec` hook
* posix_spawn on macOS exposes this tho via a macOS specific extension
to that syscall `posix_spawnattr_setexceptionports_np` but there is no
way to use that via any standard interfaces in `std::process::Command`
* thus, it seemed like a good idea to instead create our own custom
Command wrapper that on non-macOS hosts is a zero-cost wrapper of
`smol::process::Command`, while on macOS we reimplement the minimum to
achieve `smol::process::Command` with `posix_spawn` under-the-hood
Notably, this changeset improves git-blame in very large repos
significantly.
Release Notes:
- Fixed performance spawning child processes on macOS by always forcing
`posix_spawn` no matter what.

Closes#47489
The search worker pool was sized as `num_cpus - 1`, which spawned zero
workers when a devcontainer exposed only 1 CPU. All search channels
closed immediately and the search yielded zero results, while file
finder and LSP symbols worked fine.
The fix ensures at least 1 worker is always spawned: `(num_cpus -
1).max(1)`. A `num_cpus` override on `TestDispatcher` and a new test
reproduce the bug with `server_cx.executor().set_num_cpus(1)`.
## Manual testing
Add a `.devcontainer/` directory to a new project with these files:
```
// docker-compose.yml
services:
dev:
image: debian:bookworm-slim
cpuset: "0"
volumes:
- ..:/workspace:cached
command: sleep infinity
```
```
// devcontainer.json
{
"name": "zed-sandbox (1 CPU)",
"dockerComposeFile": "docker-compose.yml",
"service": "dev",
"workspaceFolder": "/workspace"
}
```
Build zed and point it at the new project:
```
cargo run -p zed -- ~/Repos/zed-sandbox-project
```
Open the built-in terminal, confirm `nproc` prints `1`.
Finally, run a project search (`Cmd+Shift+F`) and search for contents
that exist in it.
Results should appear 🎉
Release Notes:
- Fixed project search returning no results in devcontainers with a
single visible CPU.
Fixes#36818
Release Notes:
- Added new `global_lsp_settings.request_timeout` setting to configure
the maximum timeout duration for LSP-related operations.
Code inspired by [prior
implementation](https://github.com/zed-industries/zed/pull/38443),
though with a few tweaks here & there (like using `serde:default` and
keeping the pre-defined constant in the LSP file).

Follow-Up-For: #47243
Previously, we would detach tasks spawned to watch config files.
However, the task blocked on receiving a file event before checking if
the receiver for the updates channel was dropped, causing the task to
never exit. The fix here was to return the task explicitly, so that it
can be dropped instead of calling `.detach()` on it. There is definitely
a way to `select!` between the receiver being dropped and the next file
system event, but I couldn't figure it out in a reasonable amount of
time and decided it wasn't worth it.

- Fixed an issue where a few file descriptors would be leaked each time

## 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
