Closes https://github.com/zed-industries/zed/issues/38690 Closes #37353 ### Background On Windows, paths are normally separated by `\`, unlike mac and linux where they are separated by `/`. When editing code in a project that uses a different path style than your local system (e.g. remoting from Windows to Linux, using WSL, and collaboration between windows and unix users), the correct separator for a path may differ from the "native" separator. Previously, to work around this, Zed converted paths' separators in numerous places. This was applied to both absolute and relative paths, leading to incorrect conversions in some cases. ### Solution Many code paths in Zed use paths that are *relative* to either a worktree root or a git repository. This PR introduces a dedicated type for these paths called `RelPath`, which stores the path in the same way regardless of host platform, and offers `Path`-like manipulation APIs. RelPath supports *displaying* the path using either separator, so that we can display paths in a style that is determined at runtime based on the current project. The representation of absolute paths is left untouched, for now. Absolute paths are different from relative paths because (except in contexts where we know that the path refers to the local filesystem) they should generally be treated as opaque strings. Currently we use a mix of types for these paths (std::path::Path, String, SanitizedPath).

Zed Server
This crate is what we run at https://collab.zed.dev.
It contains our back-end logic for collaboration, to which we connect from the Zed client via a websocket after authenticating via https://zed.dev, which is a separate repo running on Vercel.
Local Development
Database setup
Before you can run the collab server locally, you'll need to set up a zed Postgres database. Follow the steps sequentially:
- Ensure you have postgres installed. If not, install with
brew install postgresql@15. - Follow the steps on Brew's formula and verify your
$PATHcontains/opt/homebrew/opt/postgresql@15/bin. - If you hadn't done it before, create the
postgresuser withcreateuser -s postgres. - You are now ready to run the
bootstrapscript:
script/bootstrap
This script will set up the zed Postgres database, and populate it with some users. It requires internet access, because it fetches some users from the GitHub API.
The script will create several admin users, who you'll sign in as by default when developing locally. The GitHub logins for the default users are specified in the seed.default.json file.
To use a different set of admin users, create crates/collab/seed.json.
{
"admins": ["yourgithubhere"],
"channels": ["zed"]
}
Testing collaborative features locally
In one terminal, run Zed's collaboration server and the livekit dev server:
foreman start
In a second terminal, run two or more instances of Zed.
script/zed-local -2
This script starts one to four instances of Zed, depending on the -2, -3 or -4 flags. Each instance will be connected to the local collab server, signed in as a different user from seed.json or seed.default.json.
Deployment
We run two instances of collab:
- Staging (https://staging-collab.zed.dev)
- Production (https://collab.zed.dev)
Both of these run on the Kubernetes cluster hosted in Digital Ocean.
Deployment is triggered by pushing to the collab-staging (or collab-production) tag in GitHub. The best way to do this is:
./script/deploy-collab staging./script/deploy-collab production
You can tell what is currently deployed with ./script/what-is-deployed.
Database Migrations
To create a new migration:
./script/create-migration <name>
Migrations are run automatically on service start, so run foreman start again. The service will crash if the migrations fail.
When you create a new migration, you also need to update the SQLite schema that is used for testing.
