62ae7fb Add global and HTTP context server timeout settings (#45378)

Click to expand commit body
### Closes 
- Maybe https://github.com/zed-industries/zed/issues/38252 (there might
be something going on with NPX too)
- Also addresses
https://github.com/zed-industries/zed/pull/39021#issuecomment-3644818347



### Why
Some more involved MCP servers timeout often, especially on first setup.
I got tired of having to set timeouts manually per server. I also
noticed a timeout could not be set for http context servers, which
causes Context7 or GitHub's remote servers to timeout at 60s sometimes.

### Overview

MCP Timeout Configuration Feature

This PR adds additional configurable timeout settings for Model Context
Protocol servers including a global timeout and the addition of timeouts
for http servers, addressing issues where servers were timing out after
a fixed 60 seconds regardless of user needs.

**Key Features:**
- **Global timeout setting** (`context_server_timeout`) - default
timeout for all MCP servers (default: 60s, max: 10min)
- **Per-server timeout overrides** - individual servers can specify
custom timeouts via `timeout` field
- **Precedence hierarchy** - per-server timeout > global timeout >
default (60s)
- **Automatic bounds checking** - enforces 10-minute maximum to prevent
resource exhaustion
- **Support for both transports** - works with stdio and HTTP-based
context servers
- **Comprehensive test coverage** - 3 new tests validating global,
override, and stdio timeout behavior
- **Full backward compatibility** - existing configurations work
unchanged with sensible defaults


### Release Notes:

- Added the ability to configure timeouts for context server tool calls.
The new global `context_server_timeout` setting controls the default
timeout (default is 60s, max: 10min). Additionally, per-server timeouts
can be configured using the `timeout` field within servers defined in
the `"context_servers" setting

84017bc Add OpenAI Responses API support with chat_completions capability flag (#39989)

Click to expand commit body
Add support for OpenAI's /responses endpoint for models that don't
support /chat/completions API. This enables compatibility with newer
model variants (`gpt-5-codex`, `gpt-5-pro`, `o3-pro`, etc) while
maintaining compatibility with existing configs

Changes:
- Add `supports_chat_completions` flag to model capabilities that
defaults to true for existing behavior
- Implement responses API client with streaming support as per [OpenAI
documentation](https://app.stainless.com/api/spec/documented/openai/openapi.documented.yml).
- Add `ResponseEventMapper` to convert responses events to completion
events for maintainer simplicity
- Update UI to allow toggling `chat_completions` capability
- Add `gpt-5-codex` model

Closes #38858

Release Notes:
- Added support for `gpt-5-codex` model

4dd54c6 vim: Fix word object count multiplier (2aw, 2iw) (#45686)

Click to expand commit body
Closes #44251

## Context

Commands like `2daw` or `c2iw` were ignoring the count multiplier
because the word text object functions (`in_word`, `around_word`)
weren't using the `times` parameter. This fix propagates the count
through these functions so all operators correctly handle multiple
words.

8813abe Enable terminal activation for uv-managed environments (#45949)

Click to expand commit body
Currently, the Python toolchain can identify `uv` and `uv-workspace`
environments (showing the correct labels in the UI), but it fails to
activate them when opening a new terminal. This is because the
activation script resolution and command generation logic were missing
for these environment kinds.

This PR adds `uv` and `uv-workspace` to the standard virtual environment
activation flow. Since `uv` creates environments with a standard `venv`
structure, we can reuse the existing `resolve_venv_activation_scripts`
logic to find and execute the appropriate `activate` scripts for
different shells.

Release Notes:

- Fixed terminal activation for `uv` and `uv-workspace` Python
environments.

01b716c terminal: Kill entire process group on Unix when stopping command (#45993)

Click to expand commit body
## Problem

When clicking Stop button on a terminal tool call (or using terminal
kill bindings), only the shell process was killed. Child processes (like
`sleep`, `npm run`, etc.) continued running as orphans.

## Solution

On Unix, use `killpg()` instead of `sysinfo::Process::kill()` to
terminate the entire foreground process group.

`tcgetpgrp()` already returns the foreground process group ID, so
`killpg()` is the correct syscall to use here.

## Testing

1. Run a long command in terminal tool (e.g. `sleep 30`)
2. Click Stop button
3. Verify with `ps aux | grep sleep` that the process is actually killed

## Notes

- This fix is Unix-only (Linux, macOS)
- Windows behavior unchanged — may need separate investigation with Job
Objects

## Release Notes

- Fixed terminal Stop button not killing child processes on Unix (Linux,
macOS)

ccce05d language: Fix reparse timeout not actually working (#45347)

Click to expand commit body
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

da99237 settings_ui: Fix theme not being configurable in certain scenarios (#46069)

Click to expand commit body
Closes https://github.com/zed-industries/zed/issues/44091

The issue here was that we were missing a proper default for
`ThemeSelection`. This is a disadvantage of not having the defaults in
code but actually in the `default.json`, so this here basically copies
the default from the `default.json` into code for the settings UI to
work properly.

UI if no theme was configured prior.

Closes #45251

In https://github.com/zed-industries/zed/pull/44532 the syntax
highlighting of JS/TS was improved, but we only used `type.builtin` for

Not all themes have this specific token and we don't use `type.builtin`

more consistent.

feb3ce3 User buffer column range when adding selection that skips soft wrap (#45594)

Click to expand commit body
When adding selections above/below with `skip_soft_wrap: true`, use
buffer column positions instead of pixel positions. This ensures
selections are placed at the same column offset in the buffer rather
than at the same visual position, which was incorrect for soft-wrapped
lines.

For example, selecting "how" in a wrapped line:

````
1. Very long line to
   show [how] a wrapped
   line would look
2. Very long line to
   show how a wrapped
   line would look
````

Now correctly adds a selection at the same buffer column in the next
line:

````
1. Very long line to
   show [how] a wrapped
   line would look
2. Very long line to
   show [how] a wrapped
   line would look
````

Closes #42137

Release Notes:

- Improved `editor: add selection above` and `editor: add selection
below` to select at the same text column when skipping soft-wrapped
lines, instead of the same visual position

e57285f gpui: Prepaint Div children with image cache (#46039)

Click to expand commit body
Closes #39914

I was able to reproduce the issue on macOS using the same README.

The root cause was that `markdown_preview_view` attaches the image cache
to the root div, and while Div correctly applies that cache during
request_layout and paint, the prepaint phase didn’t have the same
context.

Markdown is rendered through a List, and `List::prepaint` renders its
items using `layout_as_root`. That meant images were getting loaded
during prepaint without the image cache in place. When that happened,
Img fell back to the global asset loader, which retains assets
indefinitely unless explicitly cleaned up.

So every image was loaded twice:

- once during layout/paint via RetainAllImageCache (correctly released
when the preview closed)
- once during prepaint via the global asset system (never released)

The result was doubled memory usage and a leak, since the globally
loaded images stuck around after the preview was closed.

Release Notes:

- Fixed a memory leak when previewing markdown files with images

88a0b31 buffer_diff: Ensure that base text has finished parsing before completing update (#46054)

Click to expand commit body
Follow-up to #46001 

That initial fix partly addressed the issue for diffs managed by the
`GitStore`, but not for other diffs (e.g. those managed by the
`ActionLog` or `CommitView`). The underlying issue is that we switched
to using a `Buffer` to represent the diff base text, and when updating
the diff we were calling `set_text` on this buffer and not waiting for
reparsing to finish. When the base text was represented by a series of
independent `BufferSnapshot`s, this wasn't an issue because we would
parse the base text in the background as part of computing the diff
update. This PR fixes the issue by waiting on reparsing to finish after
each call to `set_text`.

Given that our existing code checks first 1024 bytes to decide whether
to bail on a binary file or not, this seems very wasteful — hence,
adjusted the code to read the "header" and check that first, and only
continue reading the entire file after the checks are successful.

I suspect this should also help the project search, esp. the crashes and
memory usage during that when many binary files are present?

Release Notes:

- Improved Zed's memory usage when attempting to open binary files

ce99e7e editor: Fix the merging of adjacent selection edits (#45363)

Click to expand commit body
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

e67818b keymap_editor: Add a "create keybinding" modal (#46030)

Click to expand commit body
Ever since we launched the keymap editor, we've received feedback about
how "_creating_" a new keybinding was not obvious. At first, I was
confused about this feedback because you can't "create" a keybinding,
you need to rather _assign it_ to an action... so what always made sense
to me was to start with searching for the action, which is an use case
we already support. Regardless, having an easy to reach "create" button,
which essentially still asks for action > keystroke > arguments (if
needed) > and context, feels like a win UX-wise; a bit of a redundant
flow that feels ultimately positive.

So, this PR adds a "Create Keybinding" button to the keymap editor,
which you can reach with `cmd-k`. That will open up a modal with an
action autocomplete, the keystroke recording input, the arguments input
(if needed), and the context input.

Closes https://github.com/zed-industries/zed/discussions/41414

This PR introduces a way to queue messages in the agent panel through
the `cmd-shift-enter` keybinding. Queued up messages get sent as soon as
the current generation wraps up. It's also possible to send a queued
message before time, effectively interrupting the ongoing generation.
You can also clean up the entire queue through another keybinding. Then,
if you normally interrupt the thread and if there are queued up
messages, those will get sent as soon as the interruption generation
wraps up. Lastly, if you queue up a message with an idle thread, that's
sent immediately, given that there can never exist a "stuck queue" with
this implementation.

5505e63 copilot: Fix panic in Copilot edit prediction due to anchor/snapshot mismatch (#46022)

Click to expand commit body
When `trim_completion()` creates new anchors from the current buffer
state, `completion.snapshot` was not being updated, leaving it with the
older snapshot from when the prediction was initially fetched. This
caused a panic in `interpolate_edits()` when trying to resolve anchors
with Lamport timestamps newer than what the old snapshot had observed.

The fix ensures that `completion.snapshot` is updated whenever new
anchors are created in `trim_completion()`, keeping the snapshot and
anchors consistent.

Closes #45956

Release Notes:

- Fixed a panic in Copilot edit predictions caused by anchor/snapshot
version mismatch
