Closes https://github.com/zed-industries/zed/issues/31380

See https://github.com/tree-sitter/tree-sitter/pull/4472 for the fix

Release Notes:

- Fixed a crash that could occur when editing YAML files.

Closes https://github.com/zed-industries/zed/issues/31565

* Looking up settings on every row was very slow in the case of large
folds, especially if there was an `.editorconfig` file with numerous
glob patterns
* Checking whether each indent guide was within a fold was very slow,
when a fold spanned many indent guides.

Release Notes:

- Fixed slowness that could happen when editing in the presence of large
folds.

This PR adds a new `intent` field to completion requests to assist in
categorizing them correctly.

Previously, we forgot to associate the `Markdown` entity to
`MarkdownElement` during `prepaint`. This caused calls to
`Context<Markdown>::notify` to not invalidate the view cache, which
meant we would have to wait for some other invalidation before seeing
the results of that initial notify.

Release Notes:

- Improved responsiveness of mouse interactions with the agent panel.

This PR introduces an inline code action indicator that shows up at the
start of a buffer line when there's enough space. If space is tight, it
adjusts to lines above or below instead. It also adjusts when cursor is
near indicator.

The indicator won't appear if there's no space within about 8 rows in
either direction, and it also stays hidden for folded ranges. It also
won't show up in case there is not space in multi buffer excerpt. These
cases account for very little because practically all languages do have
indents.

This PR also sets the existing `toolbar.code_actions` setting to `false`
in favor of this.

Release Notes:

- Added code action indicator which shows up inline at the start of the
row. This can be disabled by setting `inline_code_actions` to `false`.

I added a test to this too as one of my first steps of improving
`NewSessionModal`'s test coverage.


Release Notes:

- debugger beta: Select saved debug config when opening debug.json from
`NewSessionModal`

test that check's that each conversion works properly based on the
adapter's config validation function.

This PR adds actions for copying variable names and values and editing
variable values from the variable list. Previously these were only
accessible using the mouse. It also fills in keybindings for expanding
and collapsing entries on Linux that we already had on macOS.

Release Notes:

- Debugger Beta: Added the `variable_list::EditVariable`,
`variable_list::CopyVariableName`, and
`variable_list::CopyVariableValue` actions and default keybindings.

Closes #31375

Release Notes:

- debugger beta: Allow passing in URL instead of program for Javascript
launch request

Based on my report on discord when chatting with Anthony and Remco:
https://discord.com/channels/869392257814519848/1375129714645012530

Root Cause: Zed was incorrectly trying to execute a directory path
instead of properly invoking the debugpy module when debugpy was
installed via package managers (pip, conda, etc.) rather than downloaded
from GitHub releases.

Solution:

- Automatic Detection: Zed now automatically detects whether debugpy is
installed via pip/conda or downloaded from GitHub
- Correct Invocation: For pip-installed debugpy, Zed now uses python -m
debugpy.adapter instead of trying to execute file paths
- Added a `installed_in_venv` flag to differentiate the setup properly
- Backward Compatibility: GitHub-downloaded debugpy releases continue to
work as before
- Enhanced Logging: Added logging to show which debugpy installation
method is being used (I had to verify it somehow)

I verified with the following setups (can be confirmed with the debug
logs):
- `conda` with installed debugpy, went to installed instance
- `uv` with installed debugpy, went to installed instance
- `uv` without installed debugpy, went to github releases
- Homebrew global python install, went to github releases

Release Notes:

- Fix issue where debugpy from different environments won't load as
intended

This works the same as selecting the first history match in the new
session modal.

Release Notes:

- Debugger Beta: Added the `debugger: rerun last session` action, bound
by default to `alt-f4`.

Closes #31317

Release Notes:

- Debugger Beta: Fixed a bug that prevented keybindings for the
`StepOut` action from working.

We were trying to connect on the user's machine to the port number used
by the debugger on the remote machine, instead of the randomly-assigned
local available port.

Release Notes:

- Debugger Beta: Fixed a bug that caused connecting to a debug adapter
over SSH to hang.

Follow-up to #29625 and #30902

This PR reintroduces auto-intents for brackets in Python and fixes some
cases where an indentation would be triggered if it should not. For
example, upon typing

```python
a = []
```
and inserting a newline after, the next line would be indented although
it shoud not be.

Bracket auto-indentation was tested prior to #29625 but removed there
and the test updated accordingly. #30902 reintroduced this for all
brackets but `()`. I reintroduced this here, reverted the changes to the
test so that indents also happen after typing `()`. This is frequently
used for tuples and multiline statements in Python.

Release Notes:

- Improved auto-indentation when using round brackets in Python.

Release Notes:

- Debugger Beta: made it possible to navigate the breakpoint list using
menu keybindings.

Onboarding has been valuable, but we're moving into a new phase as our

Cherry-picked Change default diagnostics_max_severity to 'hint' (#31229)

Closes https://github.com/blopker/codebook/issues/79

Recently, the setting `diagnostics_max_severity` was changed from `null`
to `warning`in this PR: https://github.com/zed-industries/zed/pull/30316
This change has caused the various spell checking extensions to not work
as expected by default, most of which use the `hint` diagnostic. This
goes against user expectations when installing one of these extensions.

Without `hint` as the default, extension authors will either need to
change the diagnostic levels, or instruct users to add
`diagnostics_max_severity` to their settings as an additional step,
neither of which is a great user experience.

This PR sets the default `hint`, which is closer to the original
behavior before the aforementioned PR.

Release Notes:

- Changed `diagnostics_max_severity` to `hint` instead of `warning` by
default

Release Notes:

- AWS Bedrock: Added support for Claude 4.

This is a follow-up to https://github.com/zed-industries/zed/pull/31217
that removes the last turn after we get a `refusal` stop reason, as
advised by the Anthropic docs.

Meant to include it in that PR, but accidentally merged it before
pushing these changes 🤦🏻‍♂️.

Release Notes:

- N/A

This PR adds support for handling the new [`refusal` stop
reason](https://docs.anthropic.com/en/docs/test-and-evaluate/strengthen-guardrails/handle-streaming-refusals)
from Claude 4 models.

src="https://github.com/user-attachments/assets/707b04f5-5a52-4a19-95d9-cbd2be2dd86f"
/>

Release Notes:

- Added handling for `"stop_reason": "refusal"` from Claude 4 models.

This change improves `eval_extract_handle_command_output` results for
all models:

Model                       | Pass rate before | Pass rate after
----------------------------|------------------|----------------
claude-3.7-sonnet           |  0.96            | 0.98
gemini-2.5-pro              |  0.35            | 0.86
gpt-4.1                     |  0.81            | 1.00

Part of this improvement comes from more robust evaluation, which now
accepts multiple possible outcomes. Another part is from the prompt
adaptation: addressing common Gemini failure modes, adding a few-shot
example, and, in the final commit, auto-rewriting instructions for
clarity and conciseness.

This change still needs validation from larger end-to-end evals.

This move was done so debug configs could use path resolution, and
saving a configuration from the new session modal wouldn't resolve paths
beforehand.

I also added an integration test to make sure path resolution happens
from an arbitrary config. The test was placed under the new session
modal directory because it has to do with starting a session, and that's
what the new session modal typically does, even if it's implicitly used
in the test.

In the future, I plan to add more tests to the new session modal too.

Release Notes:

- debugger beta: Allow configs from debug.json to resolve paths

Closes #31138

Fix edge case where adding newline if there is text afterwards end
delimiter of multiline comment, would continue the comment prefix. This
is fixed by checking for end delimiter on whole line instead of just
assuming it would always be at end.

- [x] Tests

Release Notes:

- Fixed the issue where in some cases the block comment continues to the
next line even though the comment block is already closed.
