Since our last measurements, startup time in Zed had regressed quite
significantly. This was due to several issues:
- We were loading IBMPlex, which we're not really using in the UI.
- Images were being parsed in the foreground, thus blocking the main
thread
- Language models (for semantic index and assistant) were being loaded
in the foreground, thus blocking the main thread
- Interaction with the keychain was blocking the main thread
In addition to these, with this pull request we will now deserialize the
items for a pane in parallel, as opposed to doing so sequentially.
All combined, when running the zed binary directly this brings startup
time from ~350ms to ~210ms on my machine.
Release Notes:
- Improved startup time.
We recently doubled the size of the `ELEMENT_ARENA` after someone ran
into a panic due to the arena running out of space.
This adds some logging so that we can hopefully develop a better
understanding of when the element area's allocation is elevated.
Release Notes:
- N/A
This fixes the performance problem we saw in
https://github.com/zed-industries/community/issues/2405.
In a trace we could see that if a font is missing we'd constantly look
it up and never cache that it's missing.
This changes that and does cache the font-is-missing result.
Drawback is that one would need to restart Zed after installing a
missing font that was configured in settings. That seems acceptable for
now, though.
Release Notes:
- Improved rendering performance when configured fonts are missing on
the system.

This fixes a panic we just saw on nightly. It's the first time we
see this panic, so I think it's pretty safe to assume having twice as
much capacity will fix it.
This PR does some cleanup of the `gpui` docs, making sure we're linking
things appropriately and following good Rust documentation style.
Release Notes:
- N/A
This PR adds a barebones README to the `gpui` crate, just so folks have
somewhere to land on when we link them here from
[gpui.rs](https://www.gpui.rs/).
We can flesh this out as we go.
Release Notes:
- N/A
This isn't my favorite idea of a fix, but it does work for now, and it
seems likely the terminal will need to configure other aspects of action
dispatch in the future.
In the future we should explore making it possible to do this via the
keymap, either by making disabling bindings more robust; or by having a
way to indicate immediate mode per binding.
Release Notes:
- Fixed a bug where cmd-k in terminal took 1s

This optimizes rendering time by saving computation of the layer_id and
comparison when inserting it into the `BTreeMaps`.

I was unable to run the collab tests locally because I would run out of
file descriptors.
From some digging it turned out that tokio allocates a new file
descriptor to do work on the CurrentThread using KQUEUE.
We create a new tokio Runtime with each database connection, and these
database connections were being retained by the Client, which is
retained by the Context.
Cleaning up our leaked contexts (and an unrelated retain cycle in the
UserStore) fixes the problem (though does make me
wonder if a different approach might be preferrable).

- it seems like layer.drawable_size() is 0,0 in metal_renderer.rs:189
- we set this in two places:
- in response to a CALayerDelegate setFrameSize: event
- in response to a CALayerDelegate viewDidChangeBackingProperties:
event.
- it looks like if we don't set it in either of these cases we get a
different failure mode: the view is zoomed just wrong.
- That said, I can reproduce the screenshot if .scale_factor() returns
0.
- This might happen if [nativeWindow screen] is nil, which happens when
the window is off screen.
- possible that zed started with offscreen window?
- I would expect that viewDidChangeBackingProperties would fire when
that changed.
- potential fix: default to 2.0
Release Notes:
- Fixed Zed occasionally rendering blank on laungh
([#2422](https://github.com/zed-industries/community/issues/2422)).
Add support for mapping `jk` to escape in vim mode.
This changes the behaviour of the keymatches when there are pending
matches.
Before: Even if there was a pending match, any complete matches would be
triggered and the pending state lost.
After: If there is a pending match, any complete matches are delayed by
1s, or until more keys are typed.
Release Notes:
- Added support for mapping `jk` in vim mode
([#2378](https://github.com/zed-industries/community/issues/2378)),
