I was searching for the cause of a slow startup time reported in the
above issue, and I don't think I found it, but I did find two very
noticeable slow code paths while profiling, and fixed them.
### Notes
1. When starting the JSON language server, we provide it with a JSON
schema for our settings. For the `theme` setting, the JSON schema needs
to read all of the themes in the registry, to generate a list of valid
theme names. Previously, as part of this, we were deserializing each
theme from JSON, which took a lot of CPU. Now, we don't do that.
2. When an FS event occurs within a git repository, we reload the git
status for all entries in that git repository. Previously, we did that
via a separate `libgit2` call per FS entry (including ignored entries,
so many thousands in the case of the `zed` repo). Now we do one
`libgit2` call, asking for all of the statuses. Git carries an index of
all of the files with statuses, so this is fast.
Release Notes:
- Improved the the performance of starting up a JSON language server.
- Improved the performance of handling changes to git repositories, such
as changing branches or committing.
Fixes https://github.com/zed-industries/community/issues/54
Release Notes:
- Added modifiers for opening files and symbols on a split
- Added modifiers for navigating to definition and type definitions on a
split

The PR
* changes keybindings for `Editor && mode == auto_height` context:
before, `alt-enter` and `alt-shift-enter` added new lines in such
editors, including the one from buffer search.
New bindings are the same as in `Editor && mode == full` context.
* adds `search::SelectAllMatches` action and binds it to `Alt + Enter`
by default, to select all matches of a buffer search
The behavior mimics VSCode: we do not move the screen even if all
selections are out of the visible range (Cmd+G will navigate there) and
allow reselecting the results from both pane and search field, as long
as the search is not dismissed.
Release Notes:
- Added `search::SelectAllMatches` (`Alt + Enter` default) action to
place carets and select all buffer search results
([#75](https://github.com/zed-industries/community/issues/75),
[#1749](https://github.com/zed-industries/community/issues/1749)).
We're finally doing the thing.
TODO:
- [x] Choose an approach
- Decided to add a new element just for the pane axis, containing a
slimmed down copy of the flex code.
- [x] Wire through callbacks and pointers so that data goes where it
needs to
- [x] Do the flex juggling math on resize
- [x] Update the flexes when updating the split tree
- [x] Restore the active_pane_magnification setting
- [x] Serialize an axis' flexes
Release Notes:
- Made the center pane group splits resizable. Note that resizing is
disabled if the `active_pane_magnification` setting is changed from
default.
