This PR updates the version range for v0.6.0 of the extension API to
include v0.7.0.
Since we bumped the `zed_extension_api` crate's version to v0.7.0, we
need to expand this range in order for Zed clients to be able to install
extensions built against v0.7.0 of `zed_extension_api`.
Currently no extensions that target `zed_extension_api@0.7.0` can be
installed.
Release Notes:

When we refactored settings to not pass JSON blobs around, we ended up
needing
to write *a lot* of code that just merged things (like json merge used
to do).
Use a derive macro to prevent typos in this logic.

Release Notes:
- settings: Major internal changes to settings. The primary user-facing
effect is that some settings which did not make sense in project
settings files are no-longer read from there. (For example the inline
blame settings)

Ensures build task's CWD paths use POSIX-friendly path separator on
Windows host so that `std::path::Path` ops work as expected within the
Wasm guest.
Release Notes:

Closes https://github.com/zed-industries/zed/issues/31106
This fixes an issue where you would have to manually uninstall the
release extension before installing the dev extension in case that is
locally installed.
Release Notes:
- Installing a dev extension will now automatically remove the release
extension should it be installed.
Instead of passing CWD verbatim from the Windows host with backslashes
and all, we now rewrite it into a more POSIX-happy format featuring
forward slashes which means `std::path::Path` operations now work within
WASI with Windows-style paths.
Release Notes:
- N/A
### Background
Zed extensions use WASI to access the file-system. They only have
read-write access to one specific folder called their work dir. But
extensions do need to be able to *refer* to other arbitrary files on the
user's machine. For instance, extensions need to be able to look up
existing binaries on the user's `PATH`, and request that Zed invoke them
as language servers. Similarly, extensions can create paths to files in
the user's project, and use them as arguments in commands that Zed
should run. For these reasons, we pass *real* paths back and forth
between the host and extensions; we don't try to abstract over the
file-system with some virtualization scheme.
On Windows, this results in a bit of mismatch, because `wasi-libc` uses
*unix-like* path conventions (and thus, so does the Rust standard
library when compiling to WASI).
### Change 1 - Fixing `current_dir`
In order to keep the extension API minimal, extensions use the standard
library function`env::current_dir()` to query the location of their
"work" directory. Previously, when initializing extensions, we used the
`env::set_current_dir` function to set their work directory, but on
Windows, where absolute paths typically begin with a drive letter, like
`C:`, the [`wasi-libc` implementation of
`chdir`](https://github.com/WebAssembly/wasi-libc/blob/d1793637d8afcdc730408e7b6a19a050c3336ce7/libc-bottom-half/sources/chdir.c#L21)
was prepending an extra forward slash to the path, which caused
`current_dir()` to return an invalid path.
See https://github.com/bytecodealliance/wasmtime/issues/10415
In this PR, I've switched our extension initialization function to
*bypass* wasi-libc's `chdir` function, and instead write directly to
wasi-libc's private, internal state. This is a bit of a hack, but it
causes the `current_dir()` function to do what we want on Windows
without any changes to extensions' source code.
### Change 2 - Working around WASI's relative path handling
Once `current_dir` was fixed (giving us correct absolute paths on
Windows), @kubkon and I discovered that without the spurious leading `/`
character, windows absolute paths were no longer accepted by Rust's
`std::fs` APIs, because they were now recognized as relative paths, and
were being appended to the working directory.
We first tried to override the `__wasilibc_find_abspath` function in
`wasi-libc` to make it recognize windows absolute paths as being
absolute, but that functionality is difficult to override. Eventually
@kubkon realized that we could prevent WASI-libc's CWD handling from
being linked into the WASM file by overriding the `chdir` function.
wasi-libc is designed so that if you don't use their `chdir` function,
then all paths will be interpreted as relative to `/`. This makes
absolute paths behave correctly. Then, in order to make *relative* paths
work again, we simply add a preopen for `.`. Relative paths will match
that.
### Next Steps
This is a change to `zed-extension-api`, so we do need to update every
Zed extension to use the new version, in order for them to work on
windows.

This fixes a minor issue where we would show "Removing extension ..." in
the status bar when we would actually be installing it.
Release Notes:
- Fixed an issue where installing a dev extension would show the
installation status as "removing" in the activity indicator.
This PR separates out the associated constant `KEY` from the `Settings`
trait into a new trait `SettingsKey`. This allows for the key trait to
be derived using attributes to specify the path so that the new
`SettingsUi` derive macro can use the same attributes to determine top
level settings paths thereby removing the need to duplicate the path in
both `Settings::KEY` and `#[settings_ui(path = "...")]`

## Goal
This PR creates the initial settings ui structure with the primary goal
of making a settings UI that is
- Comprehensive: All settings are available through the UI
- Correct: Easy to understand the underlying JSON file from the UI
- Intuitive
- Easy to implement per setting so that UI is not a hindrance to future
settings changes
### Structure
The overall structure is settings layer -> data layer -> ui layer.
The settings layer is the pre-existing settings definitions, that
implement the `Settings` trait. The data layer is constructed from
settings primarily through the `SettingsUi` trait, and it's associated
derive macro. The data layer tracks the grouping of the settings, the
json path of the settings, and a data representation of how to render
the controls for the setting in the UI, that is either a marker value
for the component to use (avoiding a dependency on the `ui` crate) or a
custom render function.
Abstracting the data layer from the ui layer allows crates depending on
`settings` to implement their own UI without having to add additional UI
dependencies, thus avoiding circular dependencies. In cases where custom
UI is desired, and a creating a custom render function in the same crate
is infeasible due to circular dependencies, the current solution is to
implement a marker for the component in the `settings` crate, and then
handle the rendering of that component in `settings_ui`.
### Foundation
This PR creates a macro and a trait both called `SettingsUi`. The
`SettingsUi` trait is added as a new trait bound on the `Settings`
trait, this allows the type system to guarantee that all settings
implement UI functionality. The macro is used to derived the trait for
most types, and can be modified through attributes for unique cases as
well.
A derive-macro is used to generate the settings UI trait impl, allowing
it the UI generation to be generated from the static information in our
code base (`default.json`, Struct/Enum names, field names, `serde`
attributes, etc). This allows the UI to be auto-generated for the most
part, and ensures consistency across the UI.
#### Immediate Follow ups
- Add a new `SettingsPath` trait that will be a trait bound on
`SettingsUi` and `Settings`
- This trait will replace the `Settings::key` value to enable
`SettingsUi` to infer the json path of it's derived type
- Figure out how to render `Option<T> where T: SettingsUi` correctly
- Handle `serde` attributes in the `SettingsUi` proc macro to correctly
get json path from a type's field and identity

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

This PR changes the signature of `language_names` from
```rust
pub fn language_names(&self) -> Vec<String>
// Into
pub fn language_names(&self) -> Vec<LanguageName>
```
The function previously eagerly converted `LanguageName`'s to
`String`'s, which requires the reallocation of all of the elements. The
functions get called in many places in the code base, but only one of
which actually requires the conversion to a `String`. In one case it
would do a `SharedString` -> `String` -> `SharedString` conversion,
which is now totally bypassed.

Follow-up of https://github.com/zed-industries/zed/pull/34208
Closes https://github.com/zed-industries/zed/issues/35185
Previous code assumed that extensions' language server wrappers may leak
only in static data (e.g. fields that were not cleared on deinit), but
we seem to have a race that breaks this assumption.
1. We do clean `all_lsp_adapters` field after
https://github.com/zed-industries/zed/pull/34334 and it's called for
every extension that is unregistered.
2. `LspStore::maintain_workspace_config` ->
`LspStore::refresh_workspace_configurations` chain is triggered
independently, apparently on `ToolchainStoreEvent::ToolchainActivated`
event which means somewhere behind there's potentially a Python code
that gets executed to activate the toolchian, making
`refresh_workspace_configurations` start timings unpredictable.
3. Seems that toolchain activation overlaps with plugin reload, as
`2025-07-28T12:16:19+03:00 INFO [extension_host] extensions updated.
loading 0, reloading 1, unloading 0` suggests in the issue logs.
The plugin reload seem to happen faster than workspace configuration
refresh in
https://github.com/zed-industries/zed/blob/c65da547c9aa5d798a1a71468bf253bf55d1cb09/crates/project/src/lsp_store.rs#L7426-L7456
as the language servers are just starting and take extra time to respond
to the notification.
At least one of the `.clone()`d `adapter`s there is the adapter that got
removed during plugin reload and has its channel closed, which causes a
panic later.
----------------------------
A good fix would be to re-architect the workspace refresh approach, same
as other accesses to the language server collections.
One way could be to use `Weak`-based structures instead, as definitely
the extension server data belongs to extension, not the `LspStore`.
This is quite a large undertaking near the extension core though, so is
not done yet.
Currently, to stop the excessive panics, no more `.expect` is done on
the channel result, as indeed, it now can be closed very dynamically.
This will result in more errors (and backtraces, presumably) printed in
the logs and no panics.
More logging and comments are added, and workspace querying is replaced
to the concurrent one: no need to wait until a previous server had
processed the notification to send the same to the next one.
Release Notes:
- Fixed warm-related panic happening during startup
Fixes an issue that caused Windows to fail when removing extension's
directories, as Zed had never stop any related processes.
Now:
* Zed shuts down and waits until the end when the language servers are
shut down
* Adds `impl Drop for WasmExtension` where does
`self.tx.close_channel();` to stop a receiver loop that holds the "lock"
on the extension's work dir.
The extension was dropped, but the channel was not closed for some
reason.
* Does more unregistration to ensure `Arc<WasmExtension>` with the `tx`
does not leak further
* Tidies up the related errors which had never reported a problematic
path before

Closes#32068Closes#15653
Not entirely sure that it fixes the latter issue, but I am fairly
certain given the comments in #32068 and the available logs in the
issue.
This PR fixes an issue where the Supermaven provider would not leave the
"Initializing" stage. This happened due to the downloaded binary missing
executable permissions. The change here ensures that freshly downloaded
binaries as well as existing binaries downloaded by Zed have executable
permissions set. I decided on also adding this for the latter since
existing downloads would continue to be broken and Supermaven does not
seem to change versions often given the logs provided by users.
While I was at it, I also added a `make_file_executable` to the util
crate mirroring the method of the `zed_extensions_api` and refactored
existing usages where possible to use that method instead. This makes
the code slightly more readable in my opinion, yet adds a method to
non-unix systems that practically does nothing. I can revert this should
that be preferred.
Release Notes:
- Fixed an issue where the Supermaven completion provider would not
leave the "Initializing" stage.
