Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.
## Changes
- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.
## Benefits
- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.
Follows Rust guidelines; run `./script/clippy` for verification.
- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

The only warnings remaining are links to private modules/items, but I
lack knowledge to work out if the referenced modules/items should be
made public, or if the links should be rewritten into exposed
traits/items.
Links to associated items such as trait implementations have to be
written using full markdown format such as:
... [[ `App::update_global` ]](( BorrowAppContext::update_global ))
This is due to https://github.com/rust-lang/rust/issues/74563 which
sadly prohibits fully-qualified syntax:
... [[ `<App as BorrowAppContext>::update_global` ]]

Instead of manually constructing the venv we now ask the python
toolchain for the relevant information, unifying the approach of vent
inspection

Followup to #33678, doing the same thing for all JSON Schema files
provided to json-language-server
Release Notes:
* Added warnings for unknown fields when editing `tasks.json` /
`snippets.json`.
Follow-up to: https://github.com/zed-industries/zed/pull/32637
When Zed is installed in a path containing spaces (e.g.,
`/Applications/Zed Nightly.app/Contents/MacOS/zed`), environment
variable loading fails and leaves this in the Zed log:
```
login shell exited with exit status: 127. stdout: "", stderr: "Nightly.app/Contents/MacOS/zed --printenv >&0: /Applications/Zed: No such file or directory"
```
This was not part a release (only broke in nightly), but fixes it the
issue in any case when the path to the Zed.app bundle has a space (e.g.
"Zed Nightly.app")
Release Notes:

In #31331, I made a change that prevents Zed from running with root
privileges, but I forgot about the CLI.
So if you run the CLI without the `--foreground` flag, it just freezes
without any messages. This PR fixes that.

Zed’s current method of loading environment variables from the login
shell has two issues:
1. Some shells—fish in particular—write specific escape characters to
`stdout` right before they exit. When this happens, the tail end of the
last environment variable printed by `/usr/bin/env` becomes corrupted.
2. If a multi-line value contains an equals sign, that line is
mis-parsed as a separate name-value pair.
This PR addresses those problems by:
1. Redirecting the shell command's `stdout` directly to a temporary
file, eliminating any side effects caused by the shell itself.
2. Replacing `/usr/bin/env` with `sh -c 'export -p'`, which removes
ambiguity when handling multi-line values.
Additional changes:
- Correctly set the arguments used to launch a login shell under `csh`
or `tcsh`.
- Deduplicate code by sharing the implementation that loads environment
variables on first run with the logic that reloads them for a project.
Release Notes:

Related to #31460 and #28635.
Release Notes:
- Fixed redraw delay of documentation from language server completions
and added caching to reduce flicker when using arrow keys to change
selection.
Editing JSON styles is not very helpful for bringing style changes back
to the actual code. This PR adds a buffer that pretends to be Rust,
applying any style attribute identifiers it finds. Also supports
completions with display of documentation. The effect of the currently
selected completion is previewed. Warning diagnostics appear on any
unrecognized identifier.

Adds a `#[derive_inspector_reflection]` macro which allows these methods
to be enumerated and called by their name. The macro code changes were
95% generated by Zed Agent + Opus 4.
Release Notes:
* Added an element inspector for development. On debug builds,
`dev::ToggleInspector` will open a pane allowing inspecting of element
info and modifying styles.
Don't hard wrap interactively; instead, soft wrap in `Bounded` mode
(editor width or 72 chars, whichever is smaller), and then hard wrap
before sending the commit message to git.
This also makes the soft wrap mode and width for commit messages
configurable in language settings.
Previously we didn't support soft wrap modes other than `EditorWidth` in
auto-height editors; I tried to add support for this by analogy with
code that was already there, and it seems to work pretty well.
Closes#27508
Release Notes:
- Fixed confusing wrapping behavior in commit message editors.
This PR allows DAPs to define their own schema so users can see
completion items when editing their debug.json files.
Users facing this aren’t the biggest chance, but behind the scenes, this
affected a lot of code because we manually translated common fields from
Zed's config format to be adapter-specific. Now we store the raw JSON
from a user's configuration file and just send that.
I'm ignoring the Protobuf CICD error because the DebugTaskDefinition
message is not yet user facing and we need to deprecate some fields in
it.
Release Notes:
- debugger beta: Show completion items when editing debug.json
- debugger beta: Breaking change, debug.json schema now relays on what
DAP you have selected instead of always having the same based values.

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`
Release Notes:

Release Notes:
- Fixed a race condition that sometimes prevented a system-installed
`node` binary from being detected.
- Fixed a bug where the `node.path` setting was not respected when
invoking npm.
For some reason `SIGTTIN` sometimes gets sent to the process group,
causing it to stop when run from a terminal. This solves that issue by
putting the shell in a new session + progress group.
This allows removal of a workaround of using `exit 0;` to restore
handling of ctrl-c after exit. In testing this appears to no longer be
necessary.
Closes#27716
Release Notes:
- Fixed Zed sometimes becoming a stopped background process when run
from a terminal.

The bash tool will now truncate its output to 8192 bytes (or the last
newline before that).
We also added a global limit for any tool that produces a clearly large
output that wouldn't fit the context window.

down to an unwrap in asset_str. Let's print a path that was accessed.
Release Notes:

Modified version of #25950. We still use worktree paths, but repo paths
with a status that lie outside the worktree are not excluded; instead,
we relativize them by adding `..`. This makes the list in the git panel
match what you'd get from running `git status` (with the repo's worktree
root as the working directory).
- [x] Implement + test new unrelativization logic
- [x] ~~When collecting repositories, dedup by .git abs path, so
worktrees can share a repo at the project level~~ dedup repos at the
repository selector layer, with repos coming from larger worktrees being
preferred
- [x] Open single-file worktree with diff when activating a path not in
the worktree

Hi Zed team! 👋
As a fan of Zed Editor who's excited to contribute, I noticed a small
optimization opportunity in the JSON merging utilities.
<b>Changes:</b>
Removed redundant key.clone() calls in insert() operations within 2
functions:
1. merge_json_value_into
2. merge_non_null_json_value_into
<b>Why:</b>
Since we're already moving ownership of `source_object` 's contents and
key is no longer used further, we could directly pass `key` to `insert`
without cloning.
Eliminates redundant allocations, improving performance slightly for
JSON-heavy operations.
<b>Testing:</b>
I have tested this locally and all existing tests passed. The change
preserves behavior while removing redundancy.
Love using Zed and happy to contribute! Let me know if any adjustments
are needed!
Release Notes:

Motivation for this is using markdown for keymap error notifications in
#23113, but it also benefits the copied text of repl tables.

I'm consistently getting the following error on startup:
```
2025-01-05T14:45:43.4602865+01:00 [ERROR] SHELL environment variable is not assigned so we can't source login environment variables
Caused by:
environment variable not found
```
The source function, `load_login_shell_environment`, assumes a UNIX
environment and should therefore not be called on Windows. (Unless you
are using git bash?)
Release Notes:
* N/A
* Skip walking string for truncate when byte len is <= char limit
* Fix `truncate_and_remove_front` returning string that is `max_chars +
1` in length. Now more consistent with `truncate_and_trailoff` behavior.
* Fix `truncate_and_remove_front` adding ellipsis when max_chars == char
length
Release Notes:
- N/A
* Removes `max_results` from the matcher interface as this is better
dealt with in consumers once all results are known. The current
implementation was quite inefficient as it was using binary search to
find insertion points and then doing an insert which copies the entire
suffix each time.
* There was a corner case where if the binary search found a match
candidate with the same score, it was dropped. Now fixed.
* Uses of `util::extend_sorted` when merging results from worker threads
also repeatedly uses binary search and insertion which copies the entire
suffix. A followup will remove that and its usage.
* Adds `util::truncate_to_bottom_n_sorted_by` which uses quickselect +
sort to efficiently get a sorted count limited result.
* Improves interface of Matcher::match_candidates by providing the match
positions to the build function. This allows for removal of the `Match`
trait. It also fixes a bug where the Match's own Ord wasn't being used,
which seems relevant to PathMatch for cases where scores are the same.
