When the mouse cursor moves into the whitespace of a line within a
multi-line diagnostic range, the hover popover would previously
disappear. This change adds a check to keep the diagnostic hover visible
if the mouse row intersects with the active diagnostic's range.
Fixes#46841
Release Notes:
- Improved hover behavior for multi-line diagnostics to persist when
hovering over whitespace.

Before, both rust-analyzer's LSPext tasks and tree-sitter tasks were
queried on the entire multi buffer range.
The PR moves all runnable-related logic into a submodule, and reworks
the logic to consider only the visible buffers.
Singleton buffers have their tasks resolved for the entire range still
(same as LSPext tasks work), multi buffers have their buffers' data
cached and reused.
Release Notes:
- Improved multi buffer's runnables resolution performance

This PR fixes the merge conflict notification by making it appear only
once per a given set of conflicted paths, as opposed to showing every

Fixes a panic in livekit's process_reverse_stream for non-matching
channel counts, e.g., upmixing 2->4, or downmixing 2->1.
Release Notes:
- Fixed a panic in livekit when joining a channel using legacy audio
using a device with less or more than 2 channels.
Run `pylsp --version` via `delegate.try_exec()` in both branches of
`PyLspAdapter::check_if_user_installed` before returning the binary. If
execution fails (broken shebang, missing interpreter, etc.), log a
warning and return None so the system falls through gracefully instead
of surfacing an error dialog.
This matches the existing validation pattern used by TyLspAdapter and
RuffLspAdapter in their `fetch_server_binary` implementations.
No idea if this closes an issue but it sure was annoying on a system
where I deleted the pylsp environment I had. It surprised me too since I
had pylsp disabled in settings.
Release Notes:
- Fixed detection of when `pylsp` is not installed properly on a user's
system so that it doesn't get launched as an LSP when it doesn't exist.

String panics are a non-trivial percentage of the crashes we see at Zed,
and
doubly unfortunately they may incidentally include the contents of a
user's
buffer.
Although this hasn't happened yet (to my knowledge), I don't want to be
in the position of having received sensitive information this way.

This PR adds a bool method to the `ListItem` that allows to turn on the

I did a search for `/^line_comments = .*[^\s\[]"/` to identify these 3
languages:
- Git Commit
- Go Mod
- Go Work
that don't add/remove a trailing space for inline comments. I couldn't
find any indication that the absence of the trailing space is due to any
peculiarity of these languages.
---
For Git Commit, I should note that (strictly speaking) the comment
character is a single `#` without a trailing space, as Git removes any
line starting with the default comment character (`#`) (see
https://git-scm.com/docs/git-config#Documentation/git-config.txt-corecommentChar).
But I believe this change only affects whether `editor::ToggleComments`
adds/removes the space, and not how the file is syntax highlighted. So
for aesthetics and consistency, it should be better to add/remove the
trailing space.

## Summary
This fix addresses the cross-platform root cause identified in issue
#38109 where open buffers go stale or empty when external tools write
files.
## The Problem
The buffer's `file_updated()` method was only comparing `mtime` to
determine if a buffer needed to be reloaded. This caused a race
condition when external tools write files using `std::fs::write()`,
which uses `O_TRUNC` and creates a brief window where the file is 0
bytes:
1. Scanner re-stats → sees 0 bytes, mtime T
2. `file_updated()` sees mtime changed → emits `ReloadNeeded`
3. Buffer reloads to empty, stamps `saved_mtime = T`
4. Tool finishes writing → file has content, but mtime is still T (or
same-second granularity)
5. Scanner re-stats → mtime T matches `saved_mtime` → **no reload
triggered**
6. Buffer permanently stuck empty
## The Fix
Release Notes:
- Add the file `size` to `DiskState::Present`, so that even when mtime
stays the same, size changes (0 → N bytes) will trigger a reload. This
is the same fix that was identified in the issue by @lex00.
## Changes
- `crates/language/src/buffer.rs`: Add `size: u64` to
`DiskState::Present`, add `size()` method
- `crates/worktree/src/worktree.rs`: Pass size when constructing File
and DiskState::Present
- `crates/project/src/buffer_store.rs`: Pass size when constructing File
- `crates/project/src/image_store.rs`: Pass size when constructing File
- `crates/copilot/src/copilot.rs`: Update test mock
## Test plan
- [ ] Open a file in Zed
- [ ] Write to that file from an external tool (e.g., `echo "content" >
file`)
- [ ] Verify the buffer updates correctly without needing to reload

Closes#48697
Supersedes #48698
Related to #38109
## Problem
If you edit a file and an external tool writes to it while you have
unsaved changes, Zed tracks the new file but skips the reload to
preserve your edits. If you then undo everything, the buffer goes back
to clean but still shows the old content. The disk has moved on, but
nothing triggers a reload.
## Fix
In `did_edit()`, when the buffer transitions from dirty to clean, check
if the file's mtime changed while it was dirty. If so, emit
`ReloadNeeded`. Only fires for files that still exist on disk
(`DiskState::Present`).
7 lines in `crates/language/src/buffer.rs`.
### No double reload
`file_updated()` suppresses `ReloadNeeded` when the buffer is dirty
(that's the whole bug). So by the time `did_edit()` fires on
dirty-to-clean, no prior reload was emitted for this file change. The
two paths are mutually exclusive.
## Test plan
- New: `test_dirty_buffer_reloads_after_undo`
- No regression in `test_buffer_is_dirty` or other buffer tests
- All project integration tests pass
- clippy clean
Release Notes:
- Fixed an issue where buffer content could become stale after undoing
edits when an external tool wrote to the file while the buffer was
dirty.

This should be the last step in implementing full git worktree support
in the `GitStore`. We still need to add UI for that allows a user to
rename a git worktree and, by extension git branches if we use the git
picker to do so.
Also, I added a helper function called `disallow_guest_request::<T>` to
the `Collab::rpc` that is used to specify a proto request isn't allowed
to be sent by a guest. This enabled me to add a regression test that
checks that a guest isn't allowed to delete a git worktree, without the
test hanging forever because it's waiting for the proto server to
respond.
Since SSH connections send the proto message directly from client to
remote host, this won't affect those requests.

This PR adds a "Resolve with Agent" button in each merge conflict block,
as well as "Resolve Conflicts with Agents" button on a notification for
resolving conflicts across all the files that have any. When clicking on
either of these buttons, the agent panel opens up with a template prompt
auto-submitted. For the first case, the specific content of the merge
block is already attached as context for the agent to act quickly, given
it's a local and small context. For the second case (all conflicts
across the codebase), the prompt just indicates to the agent which files
have conflicts and then it's up for the agent to see them. This felt
like a simpler way to go as opposed to extracting the content for all
merge conflicts across all damaged files.
Here's how the UI looks like:

Fixes#51048
The "Copy Command" button uses `.visible_on_hover(group)` from GPUI to
only appear when the user hovers over its parent container. In
`render_collapsible_command` (used to render the code blocks for
terminal tool calls like "Run Command"), the parent `v_flex()` container
was missing the `.group()` assignment. This caused the copy button to
never become visible, which became apparent when an agent session was
restored from history.
This commit adds `.group(group.clone())` to the root `v_flex()`
container in `render_collapsible_command` to restore the hover
visibility for the "Copy Command" button.

Closes#48284
## Summary
- Fix `project_panel::RevealInFileManager` when no project panel entry
is selected.
- Preserve existing selected entry behavior.
- Add fallback to reveal the last visible worktree root when selection
is empty.
- Add regression test cov.
## Root Cause
`RevealInFileManager` previously depended on `selected_sub_entry()`.
When selection is cleared (e.g. click project panel background), Command
Palette dispatch had no target and no-op'd.
## Verification
- `cargo fmt --all -- --check`
- `./script/check-keymaps`
- `./script/clippy -p project_panel`
- `cargo test -p project_panel -- --nocapture`
## Manual Testing
- Reproduced issue steps from #48284.
- Confirmed Command Palette `Project panel: Reveal in file manager` now
opens project root when selection is empty.
- Confirmed selected file reveal behavior remains unchanged.
- Confirmed context menu reveal behavior remains unchanged.
Release Notes:
- Fixed `Project panel: Reveal in file manager` to work even when no
project panel entry is selected.
## Summary
Fixes Windows file-open parsing for names like `main (1).log`.
`PathWithPosition::parse_str` could treat `(1)` in a normal filename as
a position suffix and drop the extension/path tail. The regex is now
anchored so parenthesized row/column parsing only applies at the end of
the filename (with optional trailing `:` and optional range suffix).
## Testing
- `cargo test -p util path_with_position_parse_`
Closes#50597
Release Notes:
- Fixed opening files with names like `main (1).log` on Windows.
This PR makes the "Open Project" button in the sidebar also open the
"Recent Projects" popover, while also anchoring that popover to the the
button on the sidebar instead.

This PR changes `fs.rename` to use the platform’s atomic no-overwrite
rename on all platforms when `overwrite` is `false`. This fixes a case
where concurrent renames to the same target could race past a separate
metadata check and end up overwriting each other.
In Project Panel, we can still rename entries in parallel without
worrying about OS internals not handling it correctly or making these
renames sequential.
Release Notes:
- Fixed an issue in the Project Panel where conflicting file moves could
overwrite each other instead of leaving the losing file in place.
Add custom `Deserialize` implementations for `AgentType` and
`ExternalAgent` to map old built-in variant names to current custom
agent names, while still accepting current serialized formats.

The "Expand All Files"/"Collapse All Files" button in `BufferSearchBar`
was broken for `SplittableEditor`, which is used in the project diff
view. It was happening because `ProjectDiff::as_searchable` returns an
handle to the `SplittableEditor`, which the search bar implementation
then tries to downcast to an `Editor`, which the `SplittableEditor` did
not support, so both the expand/collapse all buttons, as well as the
collapse state were broken.
Unfortunately this was accidentally introduced in
https://github.com/zed-industries/zed/pull/48773 , so this Pull Request
updates the `Item` implementation for `SplittableEditor` in order for it
to be able to act as an `Editor`.

- Fix the "Expand All Files"/"Collapse All Files" button in the project

### Problem :
The "View AI Settings" button on the Welcome page was always rendered
regardless of the disable_ai setting. This made it visible (and
non-functional) for users who had AI disabled, which was confusing.
### Fix :
- Adds an optional visibility: Option<fn(&App) -> bool> predicate field
to SectionEntry
- At render time, Section::render uses filter_map to skip entries whose
predicate returns false.
- The "View AI Settings" entry is given a predicate that checks
!DisableAiSettings::get_global(cx).disable_ai, matching the same pattern
used in `title_bar.rs` and `quick_action_bar.rs`.
- All other entries have visibility: None, meaning they are always shown
— no behaviour change for them.
