This PR allows you to customize Zed's settings within a particular
folder by creating a `.zed/settings.json` file within that folder.
Todo
* [x] respect folder-specific settings for local projects
* [x] respect folder-specific settings in remote projects
* [x] pass a path when retrieving editor/language settings
* [x] pass a path when retrieving copilot settings
* [ ] update the `Setting` trait to make it clear which types of
settings are locally overridable
Release Notes:
* Added support for folder-specific settings. You can customize Zed's
settings within a particular folder by creating a `.zed` directory and a
`.zed/settings.json` file within that folder.
This PR makes the worktree's change events more useful in a few ways:
* The changes are now described by a cheaply clone-able collection, so
that they can be used in background tasks. Right now, I'm using a simple
Arc slice.
* The `UpdatedEntries` event now captures not only changes due to FS
changes, but also newly-loaded paths that are discovered during the
initial scan.
* The `UpdatedGitRepositories` event now includes repositories whose
work-dir changed but git dir didn't change. A boolean flag is included,
to indicate whether the git content changed.
* The `UpdatedEntries` and `UpdatedGitRepositories` events are now
*used* to compute the worktree's `UpdateWorktree` messages, used to sync
changes to guests. This unifies two closely-related code paths, and
makes the host more efficient when collaborating, because the
`UpdateWorktree` message computation used to require walking the entire
`entries` tree on every FS change.
We don't need to look-up change types by an arbitrary key, but we
do need to iterate it. It would also be useful to be able to
cheaply clone the changes, to use them in a background task.
This avoids an issue where in a many-buffer multi-buffer, each modified
buffer could complete its recalc independently, causing a cascade of
repeated notifies
Now all recalcs started at the same time must complete before
A: Starting another recalc pass
B: The master notify occurring
Each buffer can still show its new diff if something else triggers it
to notify earlier, this is desirable and does not have the same negative
effects as the notify cascade as those re-layouts would need to happen
anyway
