Cole Miller 8aca6b1eda Remove gpui's dependency on async-process (#59358)
This removes gpui's dependency on the `util` crate, which depends on
async process. It now depends on `gpui_util` only, and uses
`std::process::Command` for the two cases where it was previously using
an async `Command`. This lifts the requirement of non-Zed consumers of
gpui to depend on our forked async-process (see #59156).

Richard Feldman c7fea4876d Housekeeping: Improve error handling and small fixes (#48552)
A collection of small independent fixes:

- **Visual test runner**: Replace ~20 instances of `.ok()` and `let _ =`
with `.log_err()` to avoid silently discarding errors per project
guidelines.
- **recent_projects**: Add missing `remote_connection/test-support` to
the `test-support` feature gate.
- **util/shell.rs**: Add doc comment on `supports_posix_chaining()`
explaining its relationship to tool permission pattern matching.

Richard Feldman 8f67296991 Allow always_allow for nushell, elvish, and rc (#48395)
`brush-parser` handles `;` (sequential execution) and `|` (piping) which
all these shells use, so we can safely parse their commands for
`always_allow` pattern matching.

(No release notes because granular tool permissions haven't been
released yet.)

Joseph T. Lyons d21b5f1dd6 Revert "Allow always_allow patterns for Nushell, Elvish, and Rc shells" (#48050)

Richard FeldmanandZed Zippy a0374a5a80 Allow always_allow patterns for Nushell, Elvish, and Rc shells (#47908)
## Summary

This PR extends the `always_allow` tool permission patterns to work with
Nushell, Elvish, and Rc shells. Previously, these shells were
incorrectly excluded because they don't use `&&`/`||` operators for
command chaining. However, brush-parser can safely parse their command
syntax since they all use `;` for sequential execution.

## Changes

- Add `ShellKind::Nushell`, `ShellKind::Elvish`, and `ShellKind::Rc` to
`supports_posix_chaining()`
- Split `ShellKind::Unknown` into `ShellKind::UnknownWindows` and
`ShellKind::UnknownUnix` to preserve platform-specific fallback behavior
while still denying `always_allow` patterns for unrecognized shells
- Add comprehensive tests for the new shell support
- Clarify documentation about shell compatibility

## Shell Notes

- **Nushell**: Uses `;` for sequential execution. The `and`/`or`
keywords are boolean operators on values, not command chaining.
- **Elvish**: Uses `;` to separate pipelines. Does not have `&&` or `||`
operators. Its `and`/`or` are special commands operating on values.
- **Rc (Plan 9)**: Uses `;` for sequential execution and `|` for piping.
Does not have `&&`/`||` operators.

## Security

Unknown shells still return `false` from `supports_posix_chaining()`, so
`always_allow` patterns are denied for safety when we can't verify the
shell's syntax.

(No release notes because granular tool permissions are still
feature-flagged.)

Richard FeldmanandZed Zippy 6ff5dec7b7 Fix shell injection vulnerability in terminal tool permissions (#47807)

Previously, if a user configured `^ls` as an always-allow pattern, an
attacker could craft a command like `ls && rm -rf /` which would be
auto-approved because the regex only matched the beginning of the
command string.

Now the command is parsed into individual sub-commands (`ls`, `rm -rf
/`) and EACH sub-command must match an allow pattern for auto-approval.
This prevents shell injection attacks using operators like:
- `&&` and `||` (boolean operators)
- `;` and `&` (sequential/background execution)
- `|` (pipes)
- Newlines
- Command substitution (`$()` and backticks)
- Process substitution (`<()` and `>()`)

## Matching Logic

- **always_deny**: if ANY sub-command matches, deny the entire command
- **always_confirm**: if ANY sub-command matches, require confirmation
(unless always_deny matched, in which case deny)
- **always_allow**: ALL sub-commands must match for auto-approval
(unless always_confirm or always_deny matched, in which case defer to
those)
- If parsing fails, or if the shell is unsupported, then always_allow is
disabled for this command

As usual, `always_allow_tool_actions` supercedes all of these. If it is
`true`, then we always allow all tool calls, no questions asked.

## Shell Compatibility

The shell parser only supports POSIX-like command chaining syntax (`&&`,
`||`, `;`, `|`).

**Supported shells:** Posix (sh, bash, dash, zsh), Fish 3.0+, PowerShell
7+/Pwsh, Cmd, Xonsh, Csh, Tcsh

**Unsupported shells:** Nushell (uses `and`/`or` keywords), Elvish (uses
`and`/`or` keywords), Rc (Plan 9 shell - no `&&`/`||` operators)

For unsupported shells:
- The "Always allow" UI options are hidden for the terminal tool
- If the user has `always_allow` patterns configured in settings, they
will see a `Deny` with an explanatory error message

(No release notes because granular tool permissions are behind a feature
flag.)

qystishere e265131f76 Improve bash detection on Windows (#43455)
I have git installed via [scoop](https://scoop.sh). The current
implementation finds `git.exe` in scoop's shims folder and then tries to
find `bash.exe` relative to it.

For example, `git.exe` (shim) is located at:
```
C:\Users\<username>\scoop\shims\git.exe
```

And the code tries to find `bash.exe` at:
```
C:\Users\<username>\scoop\shims\..\bin\bash.exe
```
which doesn't exist.

This PR changes the logic to first check if `bash.exe` is available in
PATH (using `which::which`), and only falls back to the git-relative
path if that fails.

Jakub KonkaandLukas Wirth d84a81e5e3 Use ShellKind::try_quote whenever we need to quote shell args (#40912)
Using `shlex` unconditionally is dangerous as it assumes the underlying
shell is POSIX which is not the case for PowerShell, CMD, or Nushell.
Therefore, whenever we want to quote the args we should utilise our
helper `util::shell::ShellKind::try_quote` which takes into account
which shell is being used to actually exec/spawn the invocation.

Marco Mihai Condrache 67d482c8a1 util: Fix shell kind in windows based on program path (#39696)
Closes #39614

The `ShellKind` struct is built on Windows' side, meaning that when
connecting to remotes, we fall back to PowerShell construction, even if
the shell program we are spawning is a unix program.

This broke tasks creation since we are using the shell kind to construct
args:


https://github.com/zed-industries/zed/blob/068bf1f7cc3da0eb00d7a4da86d27bb102b5c84b/crates/project/src/terminals.rs#L149

In normal terminals this only affected activation scripts (only place
where shell kind is used)

I don't have a Windows machine to test it, so I would appreciate any
help with testing!

Release Notes:

- Fixed an issue where tasks could not be executed in Windows WSL

Jakub Konka 84acc70b24 terminal: Clear shell after activating (#39798)
Two tweaks were required to ensure we correctly clear the shell after
running an activate script(s):
1. PowerShell upon receiving `\r\n` input, will enter the continuation
mode (>>). To avoid this, we send an "enter" key press instead `\x0d`.
2. In order to clear the terminal _after_ issuing all activation
commands, we need to take into account the asynchronous nature of the
activation process:
   - We write the command to run the script to PTY
- We send "enter" (It is now being processed by the shell) At this point
we need to wait for the shell to finish executing before we clear the
terminal. Otherwise we will create a race where we might clear the
terminal _before_ the shell finished executing the activation script(s).
   - Write `clear`/`cls` command to PTY
- Send "enter" This way we guarantee that we clear the terminal _after_
all scripts were executed.

Closes #38474

Jakub Konka a3cf6e99e1 terminal: Fix escaping arguments when using CMD as the shell (#39701)
A couple of caveats:
- We should not auto-escape arguments with Alacritty's `escape_args`
option if using CMD otherwise, the generated command will have way too
many escaped characters for CMD to parse correctly.
- When composing a full command for CMD, we need to put it in double
quotes manually: `cmd /C "activate.bat& pwsh.exe -C do_something"` so
that CMD executes the entire string as a sequence of commands.
- CMD requires `&` as a chaining operator for commands (`;` for other
shells).

Jakub Konka aa5f4614bd terminal: Escape strings with backticks rather than backslashes in PowerShell (#39657)
Closes #39007 

Strings should be escaped with backticks in PowerShell, so the following

```
\"pwsh.exe -C pytest -m \\\"some_test\\\"\"
```

becomes

```
\"pwsh.exe -C pytest -m `\"some_test`\"\"
```

Otherwise PowerShell will misinterpret the invocation resulting in
weirdness all-around such as the issue linked above.
