Stop using wrong paths for zed --diff (#56380)
Closes https://github.com/zed-industries/zed/issues/56219

Contains 3 commist:
*
https://github.com/zed-industries/zed/pull/56380/changes/a8d55273d6cddb39868a1fd669c5069a1133a373
shows better errors when CLI or main binary fail early: no backtraces,
better error context, diff file paths shown

*
https://github.com/zed-industries/zed/pull/56380/changes/d389f7ee239dcf9bfa2bfe91729d96d2c1931663
stops opening Zed if cli `--diff` path argument(s) does not exist, also
switches over async fs API on the Zed side.
This is a behavior change, as before Zed tried to open or connect to an
instance — can be reverted if needed.

With `Path::exists` check CLI will do now:

/>

If I remove that bit, Zed will now open in the same cwd where the CLI is
invoked in:

fixes an underlying bug leading to memory leak.

If on current `main`, I apply

```diff

According to
https://apple.stackexchange.com/questions/284754/what-is-the-default-working-directory-of-a-script-run-via-launchd
, the current directory of a running macOS app could be `/` if started
the way similar to how we do it via the CLI:


7bdcb61722/crates/cli/src/main.rs (L1306-L1329)

This means that every `std::env::current_dir()` is potentially dangerous
currently, as e.g. diff code tries to open this `/` as a worktree and
index it fully.
It seems that we're "ok" for now: the dangerous code is mostly in
extensions (there we set the cwd) and cli tools, and 2 places in
"development" Zed's code are left after this one is fixed.
There's one in `fs.rs` but that one is cfg-gated to Windows only hence
should not be an issue, at least the related one.

I'm not sure if this is the best way to fix the issue: setting `/` as an
app's current directory seems also wrong and maybe that invocation CLI
code could be altered somehow?
Maybe, `open_local_workspace` could be reworked somehow? 
Seems that now we need a "shared directory" for both files we diff which
seems inevitable though, hence I've went on with passing the CLI's
current dir when opening items and that fixes the `/` issue along with
the OOM for now.

Zed

Zed CI

Welcome to Zed, a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.

Developing Zed

Contributing

See CONTRIBUTING.md for ways you can contribute to Zed.

Also... we're hiring! Check out our jobs page for open roles.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If youd like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
