Re-applies what's been reverted in https://github.com/zed-industries/zed/pull/26832 with an action-related fix in https://github.com/zed-industries/zed/commit/64b5d37d324176cc7b819418f46724cd4c67393d Before, actions were resolved only if `data` is present and either of the possible fields is empty: https://github.com/zed-industries/zed/blob/e842b4eade368127f01944f1b442016edd6b292d/crates/project/src/lsp_store.rs#L1632-L1633 But Zed resolves completions and inlays once, unconditionally, and the reverted PR applied the same strategy to actions. That did not work despite the spec not forbidding `data`-less actions to be resolved. Soon, it starts to work due to https://github.com/rust-lang/rust-analyzer/pull/19369 but it seems safer to restore the original filtering code. Code lens have no issues with `data`-less resolves: https://github.com/rust-lang/rust-analyzer/blob/220d913cbcd05f9b7635179a98c685f31821a572/crates/rust-analyzer/src/handlers/request.rs#L1618-L1620 so the same approach as completions and inlays is kept: resolve once.

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.
