Rework diff rendering to allow putting the cursor into deleted text, soft-wrapping and scrolling deleted text correctly (#22994)
Closes #12553

* [x] Fix `diff_hunk_before`
* [x] Fix failure to show deleted text when expanding hunk w/ cursor on
second line of the hunk
* [x] Failure to expand diff hunk below the cursor.
* [x] Delete the whole file, and expand the diff. Backspace over the
deleted hunk, panic!
* [x] Go-to-line now counts the diff hunks, but it should not
* [x] backspace at the beginning of a deleted hunk deletes too much text
* [x] Indent guides are rendered incorrectly 
* [ ] Fix randomized multi buffer tests

Maybe:
* [ ] Buffer search should include deleted text (in vim mode it turns
out I use `/x` all the time to jump to the next x I can see).
* [ ] vim: should refuse to switch into insert mode if selection is
fully within a diff.
* [ ] vim `o` command when cursor is on last line of deleted hunk.
* [ ] vim `shift-o` on first line of deleted hunk moves cursor but
doesn't insert line
* [x] `enter` at end of diff hunk inserts a new line but doesn't move
cursor
* [x] (`shift-enter` at start of diff hunk does nothing)
* [ ] Inserting a line just before an expanded hunk collapses it

Release Notes:


- Improved diff rendering, allowing you to navigate with your cursor
inside of deleted text in diff hunks.

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:

  1. Ensure you have postgres installed. If not, install with brew install postgresql@15.
  2. Follow the steps on Brew's formula and verify your $PATH contains /opt/homebrew/opt/postgresql@15/bin.
  3. If you hadn't done it before, create the postgres user with createuser -s postgres.
  4. You are now ready to run the bootstrap script:
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:

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.
