6f3e66d Adjust stash picker design (#38789)

Click to expand commit body
Just making it more consistent with other pickers—button actions
justified to the right and timestamp directly in the list item to avoid
as much as possible relevant information tucked away in a tooltip where
using the keyboard will mostly be the main mean of interaction.

4353b61 zeta2: Compute smaller edits (#38786)

Click to expand commit body
The new cloud endpoint returns structured edits, but they may include
more of the input excerpt than what we want to display in the preview,
so we compute a smaller diff on the client side against the snapshot.

e1b57f0 sum_tree: Reduce `Cursor` size for contextless summary types (#38776)

Click to expand commit body
This reduces the size of cursor by a usize when the summary does not
require a context making Cursor usages and constructions slightly more
efficient.

This change is a bit annoying though, as Rust has no means of
specializing, so this uses a `ContextlessSummary` trait with a blanket
impl while turning the `Context` into a GAT `Context<'a>`. This means
`Summary` implies are a bit more verbose now while contextless ones are
slimmer. It does come with the downside that the lifetime in the GAT is
always considered invariant, so some lifetime splitting occurred due to
that.

d5a99d0 ollama: Remove dead code (#38550)

Click to expand commit body
The `Duration` argument in `get_models` has been unused for over a year.

The `complete` function is also unused and it has fallen behind in new
feature additions such as Authorization support. This used to exist
because ollama didn't support tools in streaming mode, `with_tools` also
existed because of that. Now however there is no reason to keep this
around.

`ChatResponseDelta ` had unnecessary `#[allow(unused)]` macros since the
fields are marked `pub`. Using `#[expect(unused)]` would've caught this.

0f7dbf5 editor: Fix APCA contrast split text runs offset (#38751)

Click to expand commit body
Closes #38576

In case of inline element rendering, we can have multiple text runs on
the same display row. There was a bug in
https://github.com/zed-industries/zed/pull/37165 which doesn't consider
this multiple text runs case. This PR fixes that and adds a test for it.

Before:

Release Notes:

- Fixed an issue where text could be incorrectly highlighted during
search when a line contained an inline color preview.

b60f19f agent: Allow to see the whole command before running it (#38747)

Click to expand commit body
Closes https://github.com/zed-industries/zed/issues/38528

In the agent panel's `thread_view.rs` file, we have a `render_tool_call`
function that controls what we show in the UI for most types of tools.
However, for some of them—for example, terminal/execute and edit
tools—we have a special rendering so we can tailor the UI for their
specific needs. But... before the specific rendering function is called,
all tools still go through the `render_tool_call`.

Problem is that, in the case of the terminal tool, you couldn't see the
full command the agent wants to run when the tool is still in its
`render_tool_call` state. That's mostly because of the treatment we give
to labels while in that state. A particularly bad scenario because
well... seeing the _full_ command _before_ you choose to accept or
reject is rather important.

This PR fixes that by essentially special-casing the terminal tool
display when in the `render_tool_call` rendering state, so to speak.
There's still a slight UI misalignment I want to fix but it shouldn't
block this fix to go out.

Here's our final result:

Release Notes:

"waiting for confirmation" state.

3646aa6 language_models: Actually override Ollama model from settings (#38628)

Click to expand commit body
The current problem is that if I specify model parameters, like
`max_tokens`, in `settings.json` for an Ollama model, they do not
override the values coming from the Ollama API. Instead, the parameters
from the API are used. For example, in the settings below, even though I
have overridden `max_tokens`, Zed will still use the API's default
`context_length` of 4k.

```
  "language_models": {
    "ollama": {
      "available_models": [
        {
          "name": "qwen3-coder:latest",
          "display_name": "Qwen 3 Coder",
          "max_tokens": 64000,
          "supports_tools": true,
          "keep_alive": "15m",
          "supports_thinking": false,
          "supports_images": false
        }
      ]
    }
  },
```

Release Notes:

- Fixed an issue where Ollama model parameters were not being correctly
overridden by user settings.

3cf6fa8 agent: Make the panel's textarea font size be controlled by `buffer_font_size` (#38726)

Click to expand commit body
Closes https://github.com/zed-industries/zed/issues/37882

Previously, every piece of text in the agent panel was controlled by
`agent_font_size`. Although it is nice to only have one setting to tweak
that, it could be a bit misleading particularly because we use
monospaced and sans-serif fonts for different elements in the panel. Any
editor/textarea in the panel, whehter it is the main message editor or
the previous message editor, uses the buffer font. Therefore, I think it
is reasonable to expect that tweaking `buffer_font_size` would also
change the agent panel's usage of buffer fonts.

With this change, regular buffers and the agent panel's message editor
will always have the same size.

Release Notes:

- agent: Made the agent panel's textarea font size follow the font size
of regular buffers. They're now both controlled by the
`buffer_font_size` setting.

2759f54 vim: Fix cursor position being set to end of line in normal mode (#38161)

Click to expand commit body
Address an issue where, in Vim mode, clicking past the end of a line
after selecting the entire line would place the cursor on the newline
character instead of the last character of the line, which is
inconsistent with Vim's normal mode expectations.

I believe the root cause was that the cursor’s position was updated to
the end of the line before the mode switch from Visual to Normal, at
which point `DisplayMap.clip_at_line_ends` was still set to `false`. As
a result, the cursor could end up in an invalid position for Normal
mode. The fix ensures that when switching between these two modes, and
if the selection is empty, the selection point is properly clipped,
preventing the cursor from being placed past the end of the line.

Related #38049 

Release Notes:

- Fixed issue in Vim mode where switching from any mode to normal mode
could end up with the cursor in the newline character

809d3bf acp: Include only path to @mentioned directory in user message (#37942)

Click to expand commit body
Nowadays, people don't expect @-mentioning a directory to include the
contents of all files within it. Doing so makes it very likely to
consume an undesirable amount of tokens.

By default, we'll now only include the path of the directory and let the
model decide how much to read via tools. We'll still include the
contents if no tools are available (e.g. "Minimal" profile is selected).

Release Notes:

- Agent Panel: Do not include the content of @-mentioned directories
when tools are available

3ac14e1 agent: Fix Gemini refusing all requests with file-based tool calls (#38705)

Click to expand commit body
Solves an issue where Google APIs refuse all requests with file-based
tool calls attached.
This seems to get triggered in the case where:

- copy_path + another file-based tool call is enabled
- default terminal is `/bin/bash` or something similar

It is unclear why this is happening, but removing the terminal commands
in those tool calls seems to have solved the issue.

Closes #37180 and #37414

Release Notes:

- agent: Fix Gemini refusing requests with certain profiles/systems.

9e73025 Fix UTF-8 character boundary panic in DirectWrite text layout (#37767)

Click to expand commit body
## Problem

Zed was crashing with a UTF-8 character boundary error when rendering
text containing multi-byte characters (like emojis or CJK characters):

```
Thread "main" panicked with "byte index 49 is not a char boundary; it is inside '…' (bytes 48..51)"
```

## Root Cause Analysis

The PR reviewer correctly identified that the issue was not in the
DirectWrite boundary handling, but rather in the text run length
calculation in the text system. When text runs are split across lines in
`text_system.rs:426`, the calculation:

```rust
let run_len_within_line = cmp::min(line_end, run_start + run.len) - run_start;
```

This could result in `run_len_within_line` values that don't respect
UTF-8 character boundaries, especially when multi-byte characters (like
'…' which is 3 bytes) get split across lines. The resulting `FontRun`
objects would have lengths that don't align with character boundaries,
causing the panic when DirectWrite tries to slice the string.

## Solution

Fixed the issue by adding UTF-8 character boundary validation in the
text system where run lengths are calculated. The fix ensures that when
text runs are split across lines, the split always occurs at valid UTF-8
character boundaries:

```rust
// Ensure the run length respects UTF-8 character boundaries
if run_len_within_line > 0 {
    let text_slice = &line_text[run_start - line_start..];
    if run_len_within_line < text_slice.len() && !text_slice.is_char_boundary(run_len_within_line) {
        // Find the previous character boundary using efficient bit-level checking
        // UTF-8 characters are at most 4 bytes, so we only need to check up to 3 bytes back
        let lower_bound = run_len_within_line.saturating_sub(3);
        let search_range = &text_slice.as_bytes()[lower_bound..=run_len_within_line];
        
        // SAFETY: A valid character boundary must exist in this range because:
        // 1. run_len_within_line is a valid position in the string slice
        // 2. UTF-8 characters are at most 4 bytes, so some boundary exists in [run_len_within_line-3..=run_len_within_line]
        let pos_from_lower = unsafe {
            search_range
                .iter()
                .rposition(|&b| (b as i8) >= -0x40)
                .unwrap_unchecked()
        };
        
        run_len_within_line = lower_bound + pos_from_lower;
    }
}
```

## Testing

- ✅ Builds successfully on all platforms
- ✅ Eliminates UTF-8 character boundary panics
- ✅ Maintains existing functionality for all text types
- ✅ Handles edge cases like very long multi-byte characters

## Benefits

1. **Root cause fix**: Addresses the issue at the source rather than
treating symptoms
2. **Performance optimal**: Uses the same efficient algorithm as the
standard library
3. **Minimal changes**: Only modifies the specific problematic code path
4. **Future compatible**: Can be easily replaced with
`str::floor_char_boundary()` when stabilized

## Alternative Approaches Considered

1. **DirectWrite boundary fixing**: Initially tried to fix in
DirectWrite, but this was treating symptoms rather than the root cause
2. **Helper function approach**: Considered extracting to a helper
function, but inlined implementation is more appropriate for this
specific use case
3. **Standard library methods**: `floor_char_boundary()` is not yet
stable, so implemented equivalent logic

The chosen approach provides the best balance of performance, safety,
and code maintainability.

edb804d go: Stop running ghost tests, fix broken `go test -run` for suites (#38167)

Click to expand commit body
Closed #33759
Closed #38166

### Summary

This PR fixes the way `go test` commands are generated for **testify
suite test methods**.
Previously, only the method name was included in the `-run` flag, which
caused Go’s test runner to fail to find suite test cases.

---

### Problem


https://github.com/user-attachments/assets/e6f80a77-bcf3-457c-8bfb-a7286d44ff71

1. **Incorrect command** was generated for suite tests:

   ```bash
   go test -run TestSomething_Success
   ```

   This results in:

   ```
   testing: warning: no tests to run
   ```

2. The correct format requires the **suite name + method name**:

   ```bash
   go test -run ^TestFooSuite$/TestSomething_Success$
   ```

Without the suite prefix (`TestFooSuite`), Go cannot locate test methods
defined on a suite struct.

---

### Changes Made

* **Updated `runnables.scm`**:

  * Added a new query rule for suite methods (`.*Suite` receiver types).
* Ensures only methods on suite structs (e.g., `FooSuite`) are matched.
  * Tagged these with `go-testify-suite` in addition to `go-test`.

* **Extended task template generation**:

  * Introduced `GO_SUITE_NAME_TASK_VARIABLE` to capture the suite name.
  * Create a `TaskTemplate` for the testify suite.

* **Improved labeling**:

* Labels now show the full path (`go test ./pkg -v -run
TestFooSuite/TestSomething_Success`) for clarity.

* **Added a test** `test_testify_suite_detection`:

* Covered testify suite cases to ensure correct detection and command
generation.

---

### Impact


https://github.com/user-attachments/assets/ef509183-534a-4aa4-9dc7-01402ac32260

* **Before**: Running a suite test method produced “no tests to run.”
* **After**: Suite test methods are runnable individually with the
correct `-run` command, and full suites can still be executed as before.

### Release Notes

* Fixed generation of `go test` commands for **testify suite test
methods**.
Suite methods now include both the suite name and the method name in the
`-run` flag (e.g., `^TestFooSuite$/TestSomething_Success$`), ensuring
they are properly detected and runnable individually.

691bfe7 search: Remove noisy buffer search logs (#38679)

Click to expand commit body
Buffer search initiates a new search every time a key is pressed in the
buffer search bar. This would cancel the task associated with any
pending searches. Whenever one of these searches was canceled Zed would
log `[search]: oneshot canceled`. This log would trigger almost on every
keypress when typing moderately fast. This PR silences these logs by not
treating canceled searches as errors.
