Closes #52239

## Summary

Note - The code in this fix is AI generated.

OpenCode ACP chats lost slash-command support after Zed restarted and a
thread was reopened. The UI no longer showed `/ for commands`, and slash
commands like `/help` were treated as unsupported.

## Root Cause

ACP available commands were treated as transient UI state instead of
durable thread state.

- `AcpThread` handled `AvailableCommandsUpdate` but did not retain the
commands on the thread
- restored thread views rebuilt `SessionCapabilities` with an empty
`available_commands` list
- the message-editor placeholder started in the wrong state for restored
threads
- live command updates could be applied to the wrong thread view

## Fix

- persisted `available_commands` on `AcpThread`
- restored `SessionCapabilities` from thread state
- reused the same command augmentation logic for restore and live update
paths
- updated live command handling to target the correct thread view
- initialized the message-editor placeholder from current command
availability
- added a regression test for the restore path

## Verification

- `cargo test -p agent_ui
conversation_view::tests::test_restored_threads_keep_available_commands
-- --exact --nocapture`
- `./script/clippy -p agent_ui --tests`

Release Notes:

- Fixed ACP slash commands disappearing after reopening restored
threads.

Closes https://github.com/zed-industries/zed/issues/53159

Recently, we changed the behavior of pickers so that hovering matches
would also select them. This makes sense for most pickers that are used
as "regular" pickers, but we have some in Zed that are not. A great
example of one is the rules library, which sort of became way less
usable with this behavior. So, this PR introduces a simple bool trait
method to the picker so that we can turn this behavior off whenever
necessary. The rules library kicks off as the only instance of it being
turned off.

Release Notes:

- Fix navigation within the rules library making it so hovering the
sidebar doesn't activate the visible rule.

When `tab_bar.show_pinned_tabs_in_separate_row` is enabled,
double-clicking the empty space on the unpinned tab row creates a new
tab, but double-clicking the empty space on the pinned tab row does
nothing.

Add the same `on_click` double-click handler to the pinned tab bar drop
target so both rows behave consistently.

Release Notes:

- Fixed double-clicking empty space in the pinned tab row not opening a
new tab when `show_pinned_tabs_in_separate_row` is enabled.

When a Docker Compose service specifies a build context, the generated
override file was replacing it with an empty context directory. This
meant Dockerfiles that reference files relative to their build context
(e.g. `COPY . /app`) would fail. The fix preserves the original build
context from the compose service, falling back to the empty context
directory only when no context was specified.

Closes #53199

Mathematically, `floor(A) + floor(B) != floor(A + B)`. The original code
calculated the hovered row by applying `.floor()` to the scrolled offset
and local offset separately before adding them together, which
incorrectly dropped fractional sub-pixels and caused an off-by-one
targeting error.

## Summary
- cap the restricted project list height inside the security modal and
make it scroll
- cap the modal body content height so the action buttons stay reachable
on smaller screens
- add a regression test that reproduces the overflow scenario with many
restricted projects in a constrained window

## Validation
- manually reproduced the overflow by opening 60 untrusted projects in a
720x620 window before the fix
- cargo test -p workspace
test_security_modal_project_list_scrolls_when_many_projects_are_restricted
- cargo check -p workspace

Release Notes:

- Fixed restricted mode dialogs overflowing past the window when many
unrecognized projects are open.

Fixes some issues concerning volume mounts in the `dev_container`
integration:
1. Docker Compose services that don't define a volumes key cause
deserialization to fail because the field was required. This field is
not strictly necessary, i.e. for other services in a docker compose
devcontainer configuration which the editor is not attached to.
1. Volume mounts where source or target is absent (e.g. `tmpfs` mounts
that only need a target) also fail to parse because both fields were
required. This makes the source key optional, matching the Docker
Compose spec.

Changes the default CLI behavior when opening directories:

- `zed foo/` now adds `foo/` as a new workspace in the active window's
MultiWorkspace and opens the sidebar, instead of creating a new window.
If `bar/` was previously open, both `foo/` and `bar/` are retained as
separate workspaces in the sidebar.
- `zed -n foo/` continues to open a new window without the sidebar
(unchanged behavior).
- `zed -a foo/` continues to add to the existing workspace (unchanged
behavior).

The new behavior is gated on `multi_workspace_enabled` (the `agent-v2`
feature flag). Without the flag, directories open in a new window as
before, avoiding a situation where the workspace gets replaced with no
sidebar to switch back.

The change is contained to `open_paths()` in
`crates/workspace/src/workspace.rs`. When no CLI flag is specified and
no existing workspace matches the paths, we now look for the active
window and set `requesting_window` so that `Workspace::new_local` adds
the new workspace to it rather than creating a new window.

Release Notes:

- N/A

### 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.

## Context

When the dev container creation modal is showing "Creating Dev
Container", clicking anywhere on the workspace backdrop dismisses the
dialog. The container creation continues in the background, but the user
loses visual feedback and the subsequent `open_remote_project` call may
fail because the modal entity is gone.

This adds an `allow_dismissal` flag to `RemoteServerProjects` that
blocks accidental dismissal (backdrop clicks, focus loss) while a dev
container is being created, but allows explicit dismissal on success or
error.

## How to Review

Small PR — two files changed:

1. **`remote_servers.rs`** (the fix): `allow_dismissal` bool field
added, set to `false` when entering Creating state, set to `true` before
emitting `DismissEvent` on success/error. `on_before_dismiss` override
checks the flag.
2. **`recent_projects.rs`** (the test): Regression test that opens a dev
container modal, simulates a backdrop click, and asserts the modal stays
open.

Closes #52879

## Summary

VS Code binds `Ctrl+R` to open recent workspaces/folders on all
platforms (Windows, macOS, and Linux). Zed already had this binding in
`default-windows.json`, but it was missing from `default-macos.json` and
`default-linux.json`.

Since `BaseKeymap::VSCode` returns no supplemental keymap file and
relies entirely on the platform default keymaps, users who selected VS
Code keybindings on macOS or Linux would not get the expected `Ctrl+R`
behavior — instead getting nothing, or having to use the non-VSCode
binding (`Alt+Cmd+O` / `Alt+Ctrl+O`).

This adds the missing binding to both platform defaults, consistent with
what Windows already had.

## Screenshot
The default keybinding in VS Code:
<img width="1512" height="319" alt="Screenshot 2026-04-01 at 07 38 09"
src="https://github.com/user-attachments/assets/12d483a3-3c52-4649-a00f-ee2b8e40bc8c"
/>


Release Notes:

- Added `Ctrl+R` keybinding for opening recent projects on macOS and
Linux, matching VS Code's default behavior on all platforms.

This PR makes it so using that button from the sidebar's recent projects
picker _does not_ add a new window with that project, but rather, add it
to the current multi-workspace/sidebar. Previously, the `Open` action
was defaulting to true even if `false` was passed to its
`create_new_window` condition.

Fixes a bug where project symbol search navigates to the wrong position
when diff hunks are expanded. The cursor would land offset by the number
of lines added by the expanded diffs (Closes #51331). Now, users
navigating to symbols via project symbol search will land on the correct
position even when diff hunks are expanded in the editor.

The fix converts the buffer position to a `multi_buffer::Anchor` before
passing it to `select_ranges`, so it resolves correctly through the diff
transform layer instead of being interpreted as a literal MultiBuffer
coordinate.

Previously, the symbol's position was passed as a raw coordinate to the
editor, which interpreted it relative to what's displayed on screen
(including expanded diff lines). The fix converts the position to an
anchor, which is tied to the actual content in the file rather than a
screen position.

Context

The markdown preview had no search functionality — pressing Ctrl+F did
nothing. This PR implements the SearchableItem trait for
MarkdownPreviewView, enabling in-pane text search with match
highlighting and navigation.

  Changes span four crates:

- project: Added SearchQuery::search_str() — a synchronous method to
search plain &str text, since the existing search() only works on
BufferSnapshot.
- markdown: Added search highlight storage to the Markdown entity and
paint_search_highlights to MarkdownElement. Extracted the existing
selection painting into a reusable paint_highlight_range helper to avoid
duplicating quad-painting logic.
- markdown_preview: Implemented SearchableItem with full match
navigation, active match tracking, and proper SearchEvent emission
matching Editor behavior.
- Keymaps: Added buffer_search::Deploy bindings to the MarkdownPreview
context on all three platforms.
  
The PR hopefully Closes
https://github.com/zed-industries/zed/issues/27154

  How to Review

1. crates/project/src/search.rs — search_str method at the end of impl
SearchQuery. Handles both Text (AhoCorasick) and Regex variants with
whole-word and multiline support.
  2. crates/markdown/src/markdown.rs — Three areas:
    - New fields and methods on Markdown struct (~line 264, 512-548)
- paint_highlight_range extraction and paint_search_highlights (~line
1059-1170)
    - The single-line addition in Element::paint (~line 2003)
3. crates/markdown_preview/src/markdown_preview_view.rs — The main
change. Focus on:
- SearchEvent::MatchesInvalidated emission in schedule_markdown_update
(line 384)
    - EventEmitter<SearchEvent> and as_searchable (lines 723, 748-754)
- The SearchableItem impl (lines 779-927), especially active_match_index
which computes position from old highlights to handle query changes
correctly
  4. Keymap files — Two lines each for Linux/Windows, one for macOS.

Previously, when there were multiple conflicts across the codebase, we
would pop a toast at the bottom right corner of the UI. A toast seemed
like a functional idea because it'd be visible from any state of the app
and thus it'd be a good place to expose the button that allows you to
quickly prompt the agent to resolve all conflicts, as opposed to
creating a thread for each individual one. However, the toast was met
with some negative (and correct) feedback, mostly because it is
interruptive, and thus can sometimes block very relevant surfaces, like
either the agent panel itself or the Git commit area.

Therefore, in this PR, I'm removing the toast and adding a button in the
status bar instead; a bit more minimal, not interruptive, and a common
place for other items that might require your attention. The status bar
can be quite busy these days, though; we can display diagnostics, LSP
status, and file names in there; conscious of that. But it felt like it
could work given this button is such a transient one that you can either
easily manually dismiss or wait for it to be auto-dismissed as you or
the agent resolves the merge conflicts.

Release Notes:

- Git: Improved how we surface the affordance to resolve codebase-wide
merge conflicts with the agent in the UI.
- Agent: Added a setting to control whether or not the button to resolve
merge conflicts with the agent should be displayed.

This PR stops us from eagerly restoring multiple workspaces when

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>`.

Some model like glm-5、kimi-k2.5 support reasoning, but require
reasoning_effort parameter

This pr add support for setting reasoing_effort for openai compatible
models

Tested using the following config:

```json
{
  "language_models": {
    "openai_compatible": {
      "My LiteLLM": {
        "available_models": [
          {
            "name": "glm-5",
            "display_name": "glm-5",
            "max_tokens": 73728,
            "reasoning_effort": "low"
          },
          {
            "name": "kimi-k2.5",
            "display_name": "kimi-k2.5",
            "max_tokens": 262144,
            "reasoning_effort": "low"
          }
        ]
      }
    }
  }
}

```

Release Notes:

- Added a setting to control `reasoning_effort` in custom
OpenAI-compatible models

It's possible to create a multibuffer anchor that points into a specific
excerpted buffer (so not min/max), but whose main buffer `text::Anchor`
isn't contained in any of the excerpts for that buffer. When summarizing
such an anchor, we map it to the multibuffer position of the start of
the next excerpt after where the anchor "should" appear. Or at least,
that's the intention, but it turned out we had some bugs in
`summary_for_anchor` and `summaries_for_anchors` that caused them to
return bizarre summaries for these anchors. This PR fixes that and also
updates `test_random_multibuffer` to actually test
`MultiBufferSnapshot::summary_for_anchor` against a reference
implementation, including for out-of-bounds anchors.

The archive view's `fuzzy_match_positions` used `chars().enumerate()`
which produces **character indices**, not **byte indices**. When thread
titles contain multi-byte UTF-8 characters (emoji, CJK, accented
characters, etc.), these character indices don't correspond to valid
byte boundaries, causing a panic in `HighlightedLabel::new` which
asserts that highlight indices are valid UTF-8 boundaries.

The fix switches to `char_indices()` and `eq_ignore_ascii_case()` to
produce correct byte positions, matching the approach already used by
the sidebar's version of the same function.

Release Notes:

- Fixed a crash when searching archived threads whose titles contain
emoji or other non-ASCII characters.

Release Notes:

* [x] It's possible to get into a state where agent panel shows a thread
that is archived

Closes #52943

## Summary
- Prefer SSH nicknames over raw hosts in remote connection display names
- Add regression tests for nickname and host fallback behavior

## Why
The `nickname` field is documented as the user-facing label for SSH
connections, but `RemoteConnectionOptions::display_name()` always
returned the raw host. That meant recent-projects UI surfaces kept
ignoring nicknames even when they were configured.

## Validation
- `cargo test -p remote ssh_display_name`
- `cargo test -p remote`

Release Notes:

- Fixed SSH recent-project labels to show configured nicknames instead
of raw hosts when available.

This PR does some significant refactoring of the `follow_tail` feature
in the GPUI list. That's only used by the agent panel's thread view and
given to the height-changing nature of streaming agent responses, we
were seeing some scroll snapping bugs upon scrolling while the thread is
generating. In the process of fixing it, we introduced a
`remeasure_items` method as an alternative to `splice` so that we could
get the remeasurement fix without scroll position changes. We already
had a `remeasure` method that did that for all of the indexes, but we
needed something more scoped out for the agent panel case, so as to not
remeasure the entire list's content on every new streamed token.

Effectively, this ends up reverting what the PR linked above introduced,
but it improved the API in the process.

Implements basic focus-follows-mouse behavior.

Right now, it's only applied in the `workspace` crate for `Pane`s, so
anything that lives outside of that container (panels and such for the
most part) won't have this behavior applied. The core logic is
implemented as an extension trait, and should be trivial to apply to
other elements as it makes sense.

Closes #8167 

Release Notes:

- Added "Focus Follows Mouse" for editor and terminal panes

When atlas tiles are rapidly allocated and freed (e.g. watching a shared
screen in Collab), a texture can become unreferenced and be removed
while GPU uploads for it are still pending. On the next frame,
`flush_uploads` indexes into the now-empty texture slot and panics:

```
  thread 'main' panicked at crates/gpui_wgpu/src/wgpu_atlas.rs:231:40:
  texture must exist...

  #11 core::option::expect_failed
  #12 gpui_wgpu::wgpu_atlas::WgpuAtlas::before_frame
  #13 gpui_wgpu::wgpu_renderer::WgpuRenderer::draw
```

This change drains pending uploads for a texture when it becomes
unreferenced in `remove`, and skips uploads for missing textures in
`flush_uploads` as a safety net.
