If the tool asks to read a path, we don't need to verify whether that
path exists on disk; an unsaved buffer with that path is fine.

Reverts zed-industries/zed#27064

Closes #26847

Release Notes:

- Updated Git panel background to use panel_background instead of
ElevationIndex::Surface.bg(cx) for consistency with other panels.
- Removed redundant GitStatusColors struct from status.rs and refactored
to use existing theme colors.
- Adjusted Color enum mappings in color.rs to reference
version_control_* colors instead of status() for better alignment with
the theme system.
- Cleaned up unused or redundant code.

When you press the "Expand Excerpt Down" button, the editor will scroll
up by the same amount to keep the button in same place. This allows you
to expand the excerpt rapidly without moving your mouse.

Closes #ISSUE

Release Notes:

- N/A

Ensuring that text between the "you" messages align with text in the
assistant response. This also creates a nice subtle hierarchy effect
where the "you" message card is wider than the message, making it
slightly easier to tell them apart.

Release Notes:

- N/A

Sometimes the model produces SEARCH queries that don't match the
indentation of the source file exactly.

When we can't find an exact match, we'll now attempt to match the lines
while being more flexible about the leading whitespace as long as all
lines are consistently offset from the source, and extend the leading
whitespace in the REPLACE string accordingly.

We weren't incrementing the output token when getting responses from the

cc @Anthony-Eid. One thing I noticed while doing this is that we do an
invalid cast here from DisplayPoint.row to MultiBufferRow. These are not
the same if you have soft-wrap enabled (or anything else in the display
map that's not in the editor).

This pull request does two things:

1. Adds a setting to force Zed to use the built-in prompts, instead of
the system provided ones. I've personally found the system prompts on
macOS often fail to respond to keyboard input, are slow to render
initially, and don't match Zed's style.
2. Makes the previously Linux-only Zed provided prompts available to
everybody using the above setting.

Release Notes:
- Added support for a built-in prompting system, regardless of platform.
Use the new `use_system_prompts` setting to control whether to use the
system provided prompts or Zed's built-in system. Note that on Linux,
this setting has no effect, as Linux doesn't have a system prompting
mechanism.

Closes #25643

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger 
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code

This PR adds a failing test `test_staging_hunks_with_delayed_fs_event`
and makes it pass

Also skips a queued read for git diff states if another read was
requested (less work)

This still doesn't catch all race conditions, but the PR is getting long
so I'll yield this and start another branch

Release Notes:

When we failed to match a search string, we were reporting the replace
string as not found, this confuses the model and can make it go into a
doom loop. This PR fixes that improves the error output in general to

By default stdenv strips all unused rpaths, but we use a few libraries
that are `dlopen`'d so we need to stop it from removing those. The
[`dontPatchELF`
flag](https://ryantm.github.io/nixpkgs/stdenv/stdenv/#var-stdenv-dontPatchELF)
disables that and makes the nix build work on wayland again.

Release Notes:

- Improved performance when using the scroll wheel and some other mouse
interactions.

Based on some cache details about GPUI `AnyView::cached` that I found in
the discussion of
https://github.com/zed-industries/zed/discussions/24260#discussioncomment-12135749,
and combined with the optimization points found in actual applications.

This change may have some scenarios that I have not considered, so I
just make a draft to put forward my ideas first for discussion.

From my analysis, `AnyView::cached` will always invalid by Div's mouse
events, because of it called `window.refresh`. I understand that (mouse
move event) this is because the interface changes related to hover and
mouse_move will be affected style, so `window.refresh` is required.
Since Div does not have the `entity_id` of View, it is impossible to
know which View should be refreshed, so the entire window can only be
refreshed.

With this change, we can reduce a lot of `render` method calls on
ScrollWheel or Mouse Event.

Tried adding a custom debugging tasks to discover two more required
properties missing from the docs.

Follow-up of https://github.com/zed-industries/zed/pull/26574/files

After that PR, settings.json stopped giving completions when `"` was
typed as a key:

https://github.com/user-attachments/assets/5ff03863-024c-4c28-a7cd-8ef48a1695d8

This goes down to 


https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/language/src/language.rs#L1736-L1748

which was empty before the PR, hence leading to lower `true` branch.
Now, when typing `"`, there's no scope according to 


https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/project/src/lsp_store.rs#L4529-L4532

return result.

Removing `json-language-server` from `scope_opt_in_language_servers`
seems to preserve the `:` fix and restore the completions behavior.


Release Notes:

- N/A

It looks like:

- https://github.com/zed-industries/zed/pull/26780

accidentally added a new event type, `AssistantThreadFeedback`, using
the old event system, that it didn't end up actually using, as the code
actually relies on using the newer (preferred) `telemetry::event!()`.

Stalebot has a maximum operations-per-run which is set at 1000. As a
result it may require multiple runs to successfully complete.

This morning it took [three
runs](https://github.com/zed-industries/zed/actions/runs/13921563707/attempts/1)
so set it to run three times two hours apart to avoid hitting github API
limits.

Release Notes:

There apparently is some amdgpu/radv bug that rendering with
multisample anti-aliasing (MSAA) results in a crash when the bounds
of a triangle list exceed 1024px, which in Zed happens with the default
buffer font size when you select a line with more than 144 characters.

This crash has been reported as #26143.

This commit introduces a workaround: you can set the
ZED_PATH_SAMPLE_COUNT=0
environment variable to disable MSAA and the error message we print
when a GPU crash is encountered with radv now suggests trying this
environment
variable as a workaround and links the respective issue.

Sidenote: MSAA was introduced in
f08b1d78ec1655a56b07c5efcd74d225d2a4b7d5
so you didn't run into this driver bug with versions < 0.173.8.

Release Notes:

- Added a workaround for an AMD Linux driver bug that causes Zed to
crash when selecting long lines.

We used to fail when this happened, but we saw the model use it as a way
to create empty files, which makes sense.

Release Notes:

- N/A

- Load syntax colors into commit message editors
- Fix name mismatches that were preventing the git commit grammar and
language config from being matched up

This PR adds the ability to filter the list of extensions by category:


https://github.com/user-attachments/assets/ea7b518e-4769-4e2e-8bbe-e75f9f01edf9

Release Notes:

- Added the ability to filter the list of extensions by category.

Quickfix of the docs as I read through and get familiar with the
assistant interface.
`prompt-library: toggle` does not appear to be a live command in
`cmd-shift-p` - instead I see `assistant: deploy prompt library`. This
change to the docs reflects that. It also notes that this command can
only be activated from within the assistant panel (the command is not
accessible from a standard editor panel).

Release Notes:

This PR changes the git commit message editors to surface git's
suggested merge message, if any, as placeholder text, as opposed to
"real" buffer text as was previously the case.

Release Notes:

- Changed git commit message editors to use placeholder text for git's
suggested merge messages

Release Notes:

- Fixed involuntary joining of lines when typing in the commit message
editor
- Fixed being unable to type whitespace after a comment character at the
start of a line in the commit message editor

###  DISCLAIMER

> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.

This involved making a change to `ContextMenu` to allow it to rebuild

their selected/unselected status. I intend to clean up the `ContextMenu`
API a bit at a later point, but that is out of scope for this PR.
