Kirill Bulatov 851bf3d499 Make file scanner less eager in non-git-tracked directory trees (#62583)
Fixes https://github.com/zed-industries/zed/issues/35780
Collab schema migration PR:
https://github.com/zed-industries/cloud/pull/3422
The corresponding database schema migration has been created in the
Cloud repo and applied to the production database.

Before, Zed scanned each and every entry in the tree down from the
directory it was opened in, except gitignored files and scan exclusions.
The approach is unchanged, if Zed detects it was open inside a git
repository: e.g. the directory open in Zed contains `.git` directory.

For the rest of the projects, 2 optimizations are made:

* Limit the depth of file scan traversal.
Now, `file_scan_depth` (default `5`) restricts Zed from traversing any
directory that has same number or more segments in its file path.


Such directories behave similar to gitignored directories: their
contents is not available in file finder, project search and project
panel, but can be lazily traversed when the directory is expanded (e.g.
project panel expands it or a nested file is open by path via terminal,
etc.)

To indicate that to the users, a status entry is shown firs time the
limitation is hit in the project:

/>

* During the scan, any git repositories that are not direct children of
the directory open in Zed (depth >= 2), are traversed and indexed
normally, but their git metadata is never fetched eagerly.

Only when Zed opens a buffer from that repo the git metadata is fetched
and applied.

All that combined now uses a way more moderate amount of CPU and RAM
when opening `~`:

src="https://github.com/user-attachments/assets/ec83e2a9-f7cc-452b-8eb7-af158284ca4e"
/>

File scan inclusions and exclusions are considered still for such
projects.
Set `file_scan_depth` to `0` to enable old behavior.
The setting is supported in the project settings, so custom values can
be set based on the project's structure.

Release Notes:

- Fixed Zed using a lot of memory and CPU in large, non-git-tracked,
directory trees

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

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.
