This PR reworks the way workspace notifications are identified to use a
new `NotificationId` type.
A `NotificationId` is bound to a given type that is used as a unique
identifier. Generally this will be a unit struct that can be used to
uniquely identify this notification.
A `NotificationId` can also accept an optional `ElementId` in order to
distinguish between different notifications of the same type.
This system avoids the issue we had previously of selecting `usize` IDs
somewhat arbitrarily and running the risk of having two independent
notifications collide (and thus interfere with each other).
This also fixes a bug where multiple suggestion notifications for the
same extension could be live at once
Fixes https://github.com/zed-industries/zed/issues/10320.
Release Notes:
- Fixed a bug where multiple extension suggestions for the same
extension could be shown at once
([#10320](https://github.com/zed-industries/zed/issues/10320)).

Currently in Zed, certain characters require pressing the key twice to
move the caret through that character. For example: "❤️" and "y̆".
The reason for this is as follows:
Currently, Zed uses `chars` to distinguish different characters, and
calling `chars` on `y̆` will yield two `char` values: `y` and `\u{306}`,
and calling `chars` on `❤️` will yield two `char` values: `❤` and
`\u{fe0f}`.
Therefore, consider the following scenario (where ^ represents the
caret):
- what we see: ❤️ ^
- the actual buffer: ❤ \u{fe0f} ^
After pressing the left arrow key once:
- what we see: ❤️ ^
- the actual buffer: ❤ ^ \u{fe0f}
After pressing the left arrow key again:
- what we see: ^ ❤️
- the actual buffer: ^ ❤ \u{fe0f}
Thus, two left arrow key presses are needed to move the caret, and this
PR fixes this bug (or this is actually a feature?).
I have tried to keep the scope of code modifications as minimal as
possible. In this PR, Zed handles such characters as follows:
- what we see: ❤️ ^
- the actual buffer: ❤ \u{fe0f} ^
After pressing the left arrow key once:
- what we see: ^ ❤️
- the actual buffer: ^ ❤ \u{fe0f}
Or after pressing the delete key:
- what we see: ^
- the actual buffer: ^
Please note that currently, different platforms and software handle
these special characters differently, and even the same software may
handle these characters differently in different situations. For
example, in my testing on Chrome on macOS, GitHub treats `y̆` as a
single character, just like in this PR; however, in Rust Playground,
`y̆` is treated as two characters, and pressing the delete key does not
delete the entire `y̆` character, but instead deletes `\u{306}` to yield
the character `y`. And they both treat `❤️` as a single character,
pressing the delete key will delete the entire `❤️` character.
This PR is based on the principle of making changes with the smallest
impact on the code, and I think that deleting the entire character with
the delete key is more intuitive.
Release Notes:
- Fix caret movement issue for some special characters

This PR fixes a potential panic that could occur when loading malformed
Wasm files.
We now use the `parse_wasm_extension_version` function that was
previously used just to extract the Zed extension API version from the
Wasm bytes as a pre-validation step. By parsing the entirety of the Wasm
file here instead of returning as soon as we find the version, the
invalid Wasm bytes are now surfaced as an `Err` instead of a panic.
We were able to replicate the panic using the following test:
```rs
#[gpui::test]
async fn test_bad_wasm(cx: &mut TestAppContext) {
init_test(cx);
let wasm_host = cx.update(|cx| {
WasmHost::new(
FakeFs::new(cx.background_executor().clone()),
FakeHttpClient::with_200_response(),
FakeNodeRuntime::new(),
Arc::new(LanguageRegistry::test(cx.background_executor().clone())),
PathBuf::from("/the/work/dir".to_string()),
cx,
)
});
let mut wasm_bytes = std::fs::read("/Users/maxdeviant/Library/Application Support/Zed/extensions/installed/dart/extension.wasm").unwrap();
// This is the error message we were seeing in the stack trace:
// range end index 267037 out of range for slice of length 253952
dbg!(&wasm_bytes.len());
// Truncate the bytes to the same point:
wasm_bytes.truncate(253952);
std::fs::write("/tmp/bad-extension.wasm", wasm_bytes.clone()).unwrap();
let manifest = Arc::new(ExtensionManifest {
id: "the-extension".into(),
name: "The Extension".into(),
version: "0.0.1".into(),
schema_version: SchemaVersion(1),
description: Default::default(),
repository: Default::default(),
authors: Default::default(),
lib: LibManifestEntry {
kind: None,
version: None,
},
themes: Default::default(),
languages: Default::default(),
grammars: Default::default(),
language_servers: Default::default(),
});
// 💥
let result = wasm_host
.load_extension(wasm_bytes, manifest, cx.executor())
.await;
dbg!(result.map(|_| ()));
```

- Fixed a crash that could occur when loading malformed Wasm extensions

There hasn't been a componentized way to create inputs or text fields
thus far due to the innate circular dependency between the `ui` and
`editor` crates. To bypass this issue we are introducing a new
`ui_text_field` crate to specifically handle this component.
`TextField` provides the ability to add stacked or inline labels, as
well as applies a standard visual style to inputs.
Example:

We'll continue to evolve this component in the near future and start
using it in the app once we've built out the needed functionality.

This panic has occured a handful of times, I think it must be the case
that:
1. Item is dropped outside of an update loop
2. The next update is this one
In that case no flush effects will have called the release observers
yet, but we cannot upgrade the WeakModel because the ref count is 0
Release Notes:
- Fixed a (rare) panic while collaborating
This PR renames `language::Buffer::new` to `language::Buffer::local` and
simplifies its interface. Instead of taking a replica id (which should
always be 0 for the local case) and a `BufferId`, which was awkward and
verbose to construct, it simply takes text and a `cx`.
It uses the `cx` to derive a `BufferId` from the `EntityId` associated
with the `cx`, which should always be positive based on the following
analysis...
We convert the entity id to a u64 using this method on `EntityId`, which
is defined by macros in the `slotmap` crate:
```rust
pub fn as_ffi(self) -> u64 {
(u64::from(self.version.get()) << 32) | u64::from(self.idx)
}
```
If you look at the type of `version` in `KeyData`, it is non-zero:
```rust
#[derive(Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Hash)]
pub struct KeyData {
idx: u32,
version: NonZeroU32,
}
```
This commit also adds `Context::reserve_model` and
`Context::insert_model` to determine a model's entity ID before it is
created, which we need in order to assign a `BufferId` in the background
when loading a buffer asynchronously.

- N/A

- Fixed#8603
For the label title of the project panel, I find that there is no place
to use to get the title of the label to do some operations, it should be
safe to modify it, but I'm not sure how we need to modify the problem, I
can think of two scenarios:
1. Modify every place where you don't want multiple lines to appear
2. Make the label only display a single line (e.g. provide a new
parameter, or a new label type?)
Followup to #10327
It can be enabled with the following setting:
"line_indicator_format": "short"
No release note, as the original change didn't go out to Preview yet.

This fixes certain shortcuts/motions on X11 like in vim mode "v i )",
where previously zed would interpret it as "v i SHIFT )" due to the x11
backend emitting key press events for modifier keys even though other
platforms like Wayland don't. This also adds support for
ModifiersChanged events to X11
Release Notes:
- Fixed vim motions like "v i )" not working on X11
