Initial investigation and Zed memory trace:
https://github.com/zed-industries/zed/issues/42845#issuecomment-3687877977

The PR consists of 2 commits:
*
[first](https://github.com/zed-industries/zed/pull/45669/changes/732d308c8d7e9af3649ac71ea65a9c029af820fc)
adds cosmetic fixes to remove backtraces from logs yet again and print
paths in quotes, as file descriptors may return empty paths.
It also stubs the cause if OOM in project panel: that one traversed all
worktrees in `for worktree_snapshot in visible_worktrees` and "accepted"
the one with empty paths + never called `entry_iter.advance();` in "no
file name found for the worktree" case, thus looping endlessly and
bloating the memory quite fast.

*
[second](https://github.com/zed-industries/zed/pull/45669/changes/7ebfe5da2fc6d32f3fa2d71c761f8b2ec26d945b)
adds something that resembles a fix: `fn current_path` on macOS used the
file handler to re-fetch the worktree root file path on worktree root
canonicalization failure.
What's odd, is that `libc::fcntl` returns `0` in the case when external
volume is not mounted, thus resulting in the `""` path string that is
propagated all the way up.

*
[third](https://github.com/zed-industries/zed/pull/45669/changes/1a7560cef3e9fac604124c19f46b1f9c7b91815f)
moves the fix down to the platform-related FS implementations

The "fix" now checks the only usage of this method inside `async fn
process_events` for an empty path and bails if that is the case.
I am not sure what is a better fix, but this stops any memory leaks and
given how bad the situation now, seems ok to merge for now with the
`TODO` comment for more clever people to fix properly later.

----------------

Now, when I disconnect the SMB share and reconnect it again, Zed stops
displaying any files in the project tree but the ones opened as editors.

As before, at first, when the share is unmounted, Zed fails to save any
changes because of the timeouts.

Later, when the share is re-connected, macOS Finder hangs still but Zed
starts to react on saves yet still only shows the files that are open as
editors.
The files can be edited and saved from now on.

Later, when Finder finally stops hanging and indicates that the share is
mounted fully, the rest of the file structure reappear in the project
panel, and all file saves are propagated, hence can be observed in the
share in Finder.

It feels that one good improvement to add on top is some "disconnected"
indicator that clearly shows that the file is not properly handles in
the OS.
This requires much more changes and thinking as nothing like that exists
in Zed yet, hence not done.

Release Notes:

- Fixed Zed OOM-ing when macOS file descriptors become invalid

Follow up to https://github.com/zed-industries/zed/pull/45311. Instead
of searching for the string in the find pasteboard as soon as the pane

This brings the terminal element's viewport culling in line with the
editor optimization in PR #44995 and the fix in PR #45077.

## Problem

When a terminal is inside a scrollable container (e.g., the Agent Panel
thread view), it would render ALL cells during prepaint, even when the
terminal was entirely outside the viewport. This caused unnecessary CPU
usage when multiple terminal tool outputs existed in the Agent Panel.

## Solution

Calculate the intersection of the terminal's bounds with the current
content_mask (the visible viewport after all parent clipping). If the
intersection has zero area, skip all cell processing entirely.

### Three code paths

1. **Offscreen** (`intersection.size <= 0`): Early exit, process 0 cells
2. **Fully visible** (`intersection == bounds`): Fast path, stream cells
directly (no allocation)
3. **Partially clipped**: Group cells by line, skip/take visible rows
only

### Key insight: filter by screen position, not buffer coordinates

The previous approach tried to filter cells by `cell.point.line`
(terminal buffer coordinates), which breaks in Scrollable mode where
cells can have negative line numbers for scrollback history.

The new approach filters by **screen position** using
`chunk_by(line).skip(N).take(M)`, which works regardless of the actual
line numbers because we're filtering on enumerated line group index.

## Testing

Added comprehensive unit tests for:
- Screen-position filtering with positive lines (Inline mode)
- Screen-position filtering with negative lines (Scrollable mode with
scrollback)
- Edge cases (skip all, positioning math)
- Unified filtering works for both modes

Manually verified:
- Terminal fully visible (no clipping) ✓
- Terminal clipped from top/bottom ✓
- Terminal completely outside viewport ✓
- Scrollable terminals with scrollback history ✓
- Selection/interaction still works ✓

Release Notes:

- Improved Agent Panel performance when terminals are scrolled
offscreen.

Co-authored-by: Danilo Leal <daniloleal09@gmail.com>

In https://github.com/zed-industries/zed/pull/45440, we're implementing
the ability to right-click in the agent panel and copy the rendered
markdown. However, that presented itself as not as straightforward as
just making the menu item fire the `CopyAsMarkdown` action because any
selection in markdown is cleared after a new mouse click, and for the
right-click copy menu item to work, we need to persist that selection
even after the menu itself is opened and the "Copy" menu item is
clicked.

This all demanded a bit of work in the markdown file itself, and given
we may want to use this functionality for other non-agent thread view
markdown use cases in the future, I felt like it'd be better breaking it
down into a separate PR that we can more easily track in the future.

The context menu still needs to be built in the place where the markdown
is created and rendered, though. This PR only adds the infrastructure
needed so that this menu can simply fire the `CopyAsMarkdown` and make
the copying work.

This PR adds the ability to favorite models for external agents—writing
to the settings in the `agent_servers` key—as well as a handful of other
improvements:

- Make the cycling keybinding `alt-enter` work for the inline assistant
as well as previous user messages
- Better organized the keybinding files removing some outdated
agent-related keybinding definitions
- Renamed the inline assistant key context to "InlineAssistant" as
"PromptEditor" is old and confusing
- Made the keybindings to rate an inline assistant response visible in
the thumbs up/down button's tooltip
- Created a unified component for the model selector tooltip given we
had 3 different places creating the same element
- Make the "Cycle Favorited Models" row in the tooltip visible only if
there is more than one favorite models

Release Notes:

- agent: External agents also now support the favoriting model feature,
which comes with a handy keybinding to cycle through the favorite list.

## Documentation Update Summary

### Changes Made

| File | Change | Related Code |
| --- | --- | --- |
| `docs/src/ai/edit-prediction.md` | Updated Codestral setup
instructions to use Settings Editor path instead of outdated
`agent::OpenSettings` action reference | Settings Editor provider
configuration flow |

### Rationale

The primary documentation update addresses outdated instructions in the
Codestral setup section. The original text referenced an
`agent::OpenSettings` action that directed users to an "Agent Panel
settings view" which no longer reflects the current UI flow. The updated
instructions now guide users through the Settings Editor with
platform-specific keyboard shortcuts and provide an alternative status
bar path.

### Review Notes

- **Codestral instructions**: Reviewers should verify the Settings
Editor navigation path (`Cmd+,` → search "Edit Predictions" →
**Configure Providers**) matches the current Zed UI
- **Status bar alternative**: The alternative path via "edit prediction
icon in the status bar" should be confirmed as accurate

## Documentation Update Summary

### Changes Made
| File | Change | Related Code |
| --- | --- | --- |
| docs/src/ai/agent-panel.md | Added documentation for `agent::PasteRaw`
action, explaining automatic @mention formatting for pasted code and how
to bypass it | PR #45254 |

### Rationale
PR #45254 ("agent_ui: Improve UX when pasting code into message editor")
introduced the `agent::PasteRaw` action, which allows users to paste
clipboard content without automatic formatting. When users copy
multi-line code from an editor buffer and paste it into the Agent panel,
Zed now automatically formats it as an @mention with file context. The
`PasteRaw` action provides a way to bypass this behavior when raw text
is preferred.

This documentation update ensures users can discover both:
1. The new automatic @mention formatting behavior
2. The keybinding to bypass it when needed

### Review Notes
- The new paragraph was placed in the "Adding Context" section,
immediately after the existing note about image pasting support—this
maintains logical flow since both relate to pasting behavior
- Uses the standard `{#kb agent::PasteRaw}` syntax for keybinding
references, consistent with other keybinding documentation in the file
- The documentation passed Prettier formatting validation without
modifications

### Condensed Version (for commit message)
```
docs(agent-panel): Document PasteRaw action for bypassing auto @mention formatting

Added explanation that multi-line code pasted from editor buffers is
automatically formatted as @mentions, with keybinding to paste raw text.

Closes #44720

Release Notes:

- Fixed dock panel button tooltips not being dismissed when toggling
panels via keyboard shortcut




**Problem:** When hovering over a dock panel button and using a keyboard
shortcut to toggle the panel, the tooltip remains visible with stale
content. This is inconsistent with mouse click behavior, where the
tooltip is dismissed on mouse down.

**Solution:** Include the panel's active state in the button's element
ID. When the state changes, the element ID changes (e.g., `"DebugPanel"`
→ `"DebugPanel-active"`), which causes GPUI to discard the old element
state including the cached tooltip.

**Testing:** Manually verified:
1. Hover over a dock panel button, wait for tooltip
2. Press keyboard shortcut to toggle the panel
3. Tooltip is now dismissed (consistent with mouse click behavior)

Draft as a base for continuing the discussion in #8008 : adds a
`SplitOperation` enum to support bindings like `["pane::SplitLeft",
{"operation": "Clear"}]`

To be discussed @MrSubidubi and others:

- Naming: Generally not happy with names yet and specifically `Empty` is
unclear, e.g., what does this mean for terminal panes? Added placeholder
code to split without cloning, but unsure what users would expect in
this case.
- ~~I removed `SplitAndMoveXyz` actions but I guess we should keep them
for backwards compatibility?~~
- May have missed details in the move implementation. Will check the
code again for opportunities to refactor more code after we agree on the
approach.
- ~~Tests should go to `crates/collab/src/tests/integration_tests.rs`?~~

Closes #8008

Release Notes:

- Add `pane::Split` mode (`{ClonePane,EmptyPane,MovePane}`) to allow
creating an empty buffer.

* Abs path trust should transitively trust all single file worktrees on
the same host
* Init worktree trust on the client side even when devcontainers are
run: remote host unconditionally checks trust, hence the client has to
keep track of it and respond with approves/declines.
Do trust all devcontainers' remote worktrees, as containers are isolated

Schema's from the language server
- Adds a post-processing step to inject schema request paths into the
settings schema in `SettingsStore::json_schema`
- Adds an implementation for fetching the schema for rust-analyzer which
fetches it from the binary it is provided with
- Similarly for ruff

/>


## Open Questions(Would be nice to get some advice here)
- Binary Fetching:
- I'm pretty sure the binary fetching is suboptimal. The main problem
here was getting access to the delegate but i figured that out
eventually in a way that i _hope_ should be fine.
- The toolchain and binary options can differ from what the user has
configured potentially leading to mismatches in the autocomplete values
returned(these are probably rarely changed though). I could not really
find a way to fetch these in this context so the provided ones are for
now just `default` values.
- For the trait API it is just provided a binary, since i wanted to use
the potentially cached binary from the CachedLspAdapter. Is that fine
our should the arguments be passed to the LspAdapter such that it can
potentially download the LSP?
- As for those LSPs with JSON schema files in their repositories i can
add the files to zed manually e.g. in
languages/language/initialization_options_schema.json, which could cause
mismatches with the actual binary. Is there a preferred approach for Zed
here also with regards to updating them?

- Fixed spurious "no checkpoint" error in agent panel

---

## Summary

`update_last_checkpoint` would call `last_user_message()` twice - once
at the start to capture the checkpoint, and again in an async closure
after the checkpoint comparison completed. If a new user message without
a checkpoint was added between these two calls, the second call would
find the new message and fail with "no checkpoint".

## Fix

Capture the user message ID at the start and use `user_message_mut(&id)`
in the async closure to find the specific message.

This PR fixes two issues with regards to markdown codeblocks rendered in
tool call input and output content display:
- the JSON code snippets weren't properly indented
- codeblocks weren't being rendered in unique containers; e.g., if you
hovered one scrollbar, all of them would also be hovered, even though
horizontal scrolling itself worked properly

Here's the end result:


https://github.com/user-attachments/assets/3d6daf64-0f88-4a16-a5a0-94998c1ba7e2

Release Notes:

- agent: Fix scrollbar and JSON indentation for tool call input/output
content's markdown codeblocks.

- Make the buttons capable of changing the editor's content
(incrementing or decrementing the value)
- Make arrow key up and down increment and decrement the editor value
- Tried to apply a bit of DRY here by creating some functions that can
be reused across the buttons and editor given they all essentially do
the same thing (change the value)
- Fixed an issue where the editor would not allow focus to move
elsewhere, making it impossible to open a dropdown, for example, if your
focus was on the number field's editor
