Before, each time any LSP feature was used on client remote, it always produced a `proto::` request that always had been sent to the host, from where returned as an empty response. Instead, propagate more language server-related data to the client, `lsp::ServerCapability`, so Zed client can omit certain requests if those are not supported. On top of that, rework the approach Zed uses to query for the data refreshes: before, editors tried to fetch the data when the server start was reported (locally and remotely). Now, a later event is selected: on each `textDocument/didOpen` for the buffer contained in this editor, we will query for new LSP data, reusing the cache if needed. Before, servers could reject unregistered files' LSP queries, or process them slowly when starting up. Now, such refreshes are happening later and should be cached. This requires a collab DB change, to restore server data on rejoin. Release Notes: - Fixed excessive LSP requests sent during remote sessions |

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.
