When I kill the remote proxy, it seems like `ssh` exits with code -1.
Since that's less than or equal to 0, this means we don't try to restart
the connection. The proxy really shouldn't exit for any reason, so let's
get rid of this check altogether.

Expanded the nim entry to include `nims` and `nimble` files
- [nims](https://nim-lang.org/docs/nims.html) is a subscript of Nim that
runs in a VM
- [nimble](https://github.com/nim-lang/nimble) files are project files
for Nim that are written in Nim
Release Notes:
- Updated Nim file aliases so icon is shown for nims/nimble files
Also ensured that we clear only the highlights of the current view
(which probably would have been the the case almost always anyway).
Release Notes:
- Fixed a small issue where highlights of the syntax tree view would
persist after the view was closed.
The client has not yet setup its own side of things so the message will
always error as being unhandled anyways.

## Summary
Fixes#47540 - Anthropic Claude models not appearing in GitHub Copilot
Chat model picker.
## Problem
Users reported that Anthropic Claude models (Claude Sonnet 4, Claude
Opus 4, etc.) were not appearing in the model picker when using GitHub
Copilot Chat, even though:
- The GitHub Copilot API returns these models
- The models have `model_picker_enabled: true`
- Users have valid Copilot subscriptions with access to these models
## Root Cause
The issue was in the `ModelSupportedEndpoint` enum deserialization. The
enum only defined two variants:
```rust
pub enum ModelSupportedEndpoint {
#[serde(rename = "/chat/completions")]
ChatCompletions,
#[serde(rename = "/responses")]
Responses,
}
```
Anthropic Claude models use the `/v1/messages` endpoint, which wasn't
defined. When deserializing the API response, serde failed with:
```
Error("unknown variant `/v1/messages`, expected `/chat/completions` or `/responses`")
```
Because the crate uses resilient deserialization via
`deserialize_models_skip_errors()`, the entire Claude model was silently
skipped rather than causing a hard failure. This meant users saw no
error - the models simply didn't appear.
## Solution
### 1. Added `/v1/messages` endpoint variant
```rust
pub enum ModelSupportedEndpoint {
#[serde(rename = "/chat/completions")]
ChatCompletions,
#[serde(rename = "/responses")]
Responses,
#[serde(rename = "/v1/messages")]
Messages, // NEW: Anthropic models use this endpoint
#[serde(other)]
Unknown, // NEW: Future-proofing for unknown endpoints
}
```
### 2. Removed incorrect `dedup_by()` call
The previous code deduplicated models by family:
```rust
.dedup_by(|a, b| a.capabilities.family == b.capabilities.family)
```
This incorrectly filtered out model variants that share the same family
(e.g., `claude-sonnet-4` and `claude-sonnet-4-thinking`). Removed this
call to preserve all model variants.
### 3. Removed unused import
Removed `use itertools::Itertools;` which was only used for the
now-removed `dedup_by()`.
## Changes
| File | Change |
|------|--------|
| `crates/copilot_chat/src/copilot_chat.rs` | Added `Messages` and
`Unknown` variants to `ModelSupportedEndpoint` enum |
| `crates/copilot_chat/src/copilot_chat.rs` | Removed `.dedup_by()` call
that incorrectly filtered models |
| `crates/copilot_chat/src/copilot_chat.rs` | Removed unused
`itertools::Itertools` import |
| `crates/copilot_chat/src/copilot_chat.rs` | Added 8 new unit tests |
## Test Coverage
Added 8 new unit tests to ensure the fix works and prevent regression:
| Test | Purpose |
|------|---------|
| `test_models_with_pending_policy_deserialize` | Verifies models with
non-"enabled" policy states deserialize correctly (they're filtered
later) |
| `test_multiple_anthropic_models_preserved` | Verifies multiple Claude
models are not incorrectly deduplicated |
| `test_models_with_same_family_both_preserved` | Verifies models
sharing the same family (e.g., thinking variants) are both preserved |
| `test_mixed_vendor_models_all_preserved` | Verifies models from
different vendors (OpenAI, Anthropic, Google) are all preserved |
| `test_model_with_messages_endpoint_deserializes` | **Critical test**:
Verifies `/v1/messages` endpoint deserializes correctly |
| `test_model_with_unknown_endpoint_deserializes` | Verifies unknown
future endpoints deserialize to `Unknown` variant |
| `test_model_with_multiple_endpoints` | Verifies models with multiple
endpoints deserialize correctly |
| `test_supports_response_method` | Verifies the `supports_response()`
method logic for endpoint routing |
### Test Results

## How to Test Manually
1. Sign in to GitHub Copilot in Zed
2. Open the model picker (Agent panel → model selector dropdown)
3. Verify that Anthropic Claude models appear in the list:
- Claude Sonnet 4
- Claude Opus 4
- Other Claude variants (if enabled in your GitHub Copilot settings)
## Checklist
- [x] Code compiles without errors
- [x] `./script/clippy --package copilot_chat` passes with no warnings
- [x] All unit tests pass
- [x] Change is focused on a single bug fix
- [x] No unrelated refactoring or feature additions

Closes#38168Closes#42414
We were already using `ExitStatusExt::from_raw()` to construct an
`ExitStatus`, but we were passing in the exit code from
alacritty_terminal's `ChildExit` event. This worked fine on Windows
where `from_raw()` expects an exit code, but on Unix, `from_raw()`
([read
more](https://doc.rust-lang.org/std/os/unix/process/trait.ExitStatusExt.html#tymethod.from_raw))
expects a raw wait status from `waitpid()` and not an exit code.
When a child process was killed by a signal (e.g., SIGSEGV),
`ExitStatus::code()` returns `None` since only normal exits have an exit
code. This caused the terminal to hang because we weren't properly
detecting the exit.
One fix would have been to remove the dependency on `ExitStatus`
entirely, but using the raw wait status gives us more information, we
can now detect exit codes, signal terminations, and more.
The actual fix was upstream in `alacritty_terminal` to send the raw wait
status instead of just the exit code.
Currently using forked patch
https://github.com/zed-industries/alacritty/tree/v0.16-child-exit-patch
which is based on v0.25.1.
Upstream PR: https://github.com/alacritty/alacritty/pull/8825
Release Notes:
- Fixed terminal hanging when a child process is killed by a signal
(e.g., SIGSEGV from null pointer dereference).
Fixes an issue where edits would be shown like this:

Release Notes:

Skipping setting the language on the git index text buffer improves
snappiness for (very) large git diff multibuffers and also significantly
lower peak and steady-state RSS. When tested on the chromium repo with
`git reset HEAD~1000` and *all* language extensions installed we notice:
* current `main`: peak RSS ~45GB, ss RSS ~39GB
* this patch: peak RSS ~30GB, ss RSS ~27GB
Release Notes:
- Improved memory usage of large git diff multibuffers.
Addressing the feedback left on a previous PR of mine:
https://github.com/zed-industries/zed/pull/46663. I feel like this is
worthy of a setting. Note, however, that this does not apply to typing
`ctrl-c` in the terminal from within the agent panel; this is purely
controlling what happens when you click on the "Stop" button in the
terminal tool call card.
Release Notes:
- Agent: Added a setting for controlling the behavior of the stop button
in the terminal tool call card (between cancelling the command to run
and the thread, or just the command).
Before this change we'd spawn N tasks in parallel on every keystroke,
afterwards
we only allow 1 background diagnostic refresh in flight at a time.
This also fixed a bug where we'd send O(n*2) pull diagnostic requests
when
re-opening a workspace with n editors.

This PR adds support for refreshing LLM tokens that are "outdated"—that
is, that are missing some required claims.
Release Notes:
- Fixed some instances of authentication errors with the Zed API that
could be resolved automatically by refreshing the token.
