Pedro GuedesandLukas Wirth 32fd4bfe74 workspace: Skip read-only paths when choosing default save location (#53100)
Fixes #42787

## Summary

- When "Go to Definition" navigates into a dependency (e.g. `.venv/`,
`node_modules/`), the save dialog for new files defaulted to that
directory
- `most_recent_active_path` now checks the `read_only_files` setting and
skips matching paths, falling back to the next eligible path, the
worktree root, or the home directory

## Design tradeoffs

We considered three approaches:

1. **Filter by `is_ignored`/`is_hidden`/`is_external` on worktree
entries** — catches `.venv` when gitignored or when it's a dotfile, but
also false-positives on directories like `.github/workflows/` that users
intentionally edit.

2. **Use preview tab status** — "Go to Definition" opens files as
preview tabs, so skipping preview paths targets the right intent. But it
doesn't work when preview tabs are disabled, and the signal is transient
(preview status changes as you interact with tabs).

3. **Use `read_only_files` setting** (this PR) — an explicit user
declaration of "I never want to edit files here." If you can't edit
them, you don't want to save new files next to them either. This is the
clearest signal of intent and respects user configuration. The tradeoff
is that `read_only_files` is empty by default, so users need to
configure it. But the kind of user bothered by the save dialog
defaulting to a dependency directory is the same kind of user who
already configures `read_only_files` (see
[#46827](https://github.com/zed-industries/zed/discussions/46827) for an
example).

## Test plan

- [x] Manual test: configured `read_only_files: ["**/.venv/**"]`, opened
project, Go to Definition into `.venv`, created new file — save dialog
defaults to project root
- [x] Added `test_most_recent_active_path_skips_read_only_paths`
- [x] All existing workspace tests pass

Release Notes:

- Fixed save dialog defaulting to dependency directories (e.g. `.venv/`,
`node_modules/`) after using Go to Definition, when those directories
are configured as `read_only_files`.

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 you’d 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.
