We started using `grid` for Markdown tables instead of flex. This
resulted in tables having a width of 0 inside popovers, since popovers
are laid out using `AvailableSpace::MinContent`.
One way to fix this is to lay out popovers using `MaxContent` instead.
But that would affect all Markdown rendered in popovers and could change
how popovers look, or regress things.
The other option is to fix it where the problem actually is:
`repeat(count, vec![minmax(length(0.0), fr(1.0))])`. Since the minimum
width here is `0`, laying things out with `MinContent` causes the
Markdown table to shrink completely. What we want instead is for the
minimum width to be the min-content size, but only for Markdown rendered
inside popovers.
This PR does exactly that, without interfering with the `grid_cols` API,
which intentionally follows a TailwindCSS-like convention. See
https://github.com/zed-industries/zed/pull/44368 for context.

## Motivating problem
The gpui API currently has this counter intuitive behaviour
```rust
div()
.id("hallo")
.cursor_pointer()
.text_color(white())
.font_weight(FontWeight::SEMIBOLD)
.text_size(px(20.0))
.child("hallo")
.active(|this| this.text_color(red()))
```
By changing the text_color when the div is active, the current behaviour
is to overwrite all of the text styling rather than do a proper
refinement of the existing text styling leading to this odd result:
The button being active inadvertently changes the font size.
https://github.com/user-attachments/assets/1ff51169-0d76-4ee5-bbb0-004eb9ffdf2c
## Solution
Previously refining a Style would not recursively refine the TextStyle
inside of it, leading to this behaviour:
```rust
let mut style = Style::default();
style.refine(&StyleRefinement::default().text_size(px(20.0)));
style.refine(&StyleRefinement::default().font_weight(FontWeight::SEMIBOLD));
assert!(style.text_style().unwrap().font_size.is_none());
//assertion passes
```
(As best as I can tell) Style deliberately has `pub text:
TextStyleRefinement` storing the `TextStyleRefinement` rather than the
absolute `TextStyle` so that these refinements can be elsewhere used in
cascading text styles down to element's children. But a consequence of
that is that the refine macro was not properly recursively refining the
`text` field as it ought to.
I've modified the refine macro so that the `#[refineable]` attribute
works with `TextStyleRefinement` as well as the usual `TextStyle`.
(Perhaps a little bit haphazardly by simply checking whether the name
ends in Refinement - there may be a better solution there).
This PR resolves the motivating problem and triggers the assertion in
the above code as you'd expect. I've compiled zed under these changes
and all seems to be in order there.

This adds implementations of `std::iter::Sum` for `Pixels`, allowing the
use of `.sum()` on iterators of `Pixels` values.
### Changes
- Implement `Sum<Pixels>` for `Pixels` (owned values)
- Implement `Sum<&Pixels>` for `Pixels` (references)
This enables ergonomic patterns like:
```rust
let total: Pixels = pixel_values.iter().sum();
```
Improves the scheduler by allowing tasks to have a set priority which
will significantly improve responsiveness.

exists.

While this fixes the link in the Readme it breaks the one in the docs
which is the more important one (we should probably just duplicate the
readme and not include it into gpui.rs but that is annoying).

When using the latest version of `GPUI`, I found some grid layout
issues. I discovered #43555 modified the default behavior of grid
template columns. I checked the implementation at
https://tailwindcss.com/docs/grid-template-columns, and it seems our
previous implementation was correct.
If a grid layout is placed inside a flexbox, the layout becomes
unpredictable.
```rust
impl Render for HelloWorld {
fn render(&mut self, _window: &mut Window, _cx: &mut Context<Self>) -> impl IntoElement {
div()
.flex()
.size(px(500.0))
.bg(rgb(0x505050))
.text_xl()
.text_color(rgb(0xffffff))
.child(
div()
.size_full()
.gap_1()
.grid()
.grid_cols(2)
.border_1()
.border_color(gpui::red())
.children((0..10).map(|ix| {
div()
.w_full()
.border_1()
.border_color(gpui::green())
.child(ix.to_string())
})),
)
}
}
```

I tested the changes from the previous PR, and it seems that setting the
table's parent to `v_flex` is sufficient to achieve a non-full table
width without modifying the grid layout. This was already done in the
previous PR.
I reverted the grid changes, the blue border represents the table width.

So, I believe we should revert to this implementation to align with
tailwindcss behavior and avoid potential future problems, especially
since the cause of this issue is difficult to pinpoint.
Release Notes:
- N/A
Make gpui's `rems()`, `phi()`, `auto()` length related helpers into
const functions.
I can't see why these functions aren't already const except that it
must've been overlooked when they were written?
In my project I had need for rems() to be const, and I thought I'd do
phi() and auto() whilst I was in the neighbourhood

Closes#44148
the existing rate == 0 check inside the timer callback already handles
disabling repeat - it just drops the timer immediately. So the fix
prevents the crash while preserving correct behavior.

`characters_per_second` was zero

In the Linux dispatcher, we create one background thread per CPU, but
when a single core is available, having a single background thread
significantly hinders the perceived performance of Zed. This is
particularly helpful when SSH remoting to low-resource servers.
We may want to bump this to more than two threads actually, but I wanted
to be conservative, and this seems to make a big difference already.

`WorkItemPriority::High` will enqueue the work items to threads with
higher-than-normal priority. If the work items are very intensive, this
can cause the system to become unresponsive. It's not clear what this
gets us, so let's avoid the responsiveness issue by deleting this.

Closes#39152
This PR fixes an issue where we would render Markdown tables full width
based on their container size. We now render tables based on their
content min size, meaning you are still allowed to make the table render
as it was before by making the columns `w_full`.
I had to change the `div()` to `v_flex().items_start()` because this
introduced a weird displaying behavior of the outside table border,
because the grid container was not shrinking due to It was always taking
up the full width of their container.

Windows applications tend to be fairly re-entrant which does not work
well with our current top-level `RefCell` approach. We have worked
around a bunch of panics in the past due to this, but ultimately this
will re-occur (and still does according to sentry) in the future. So
this PR moves all interior mutability down to the fields.

After #39928, if a font's weight changes between text runs without other
decoration changing, the earlier weight continues to be used for the
subsequent run(s).
PR #40840 fixes this in shape_text, but similar code exists also in
layout_text. The latter is used for text in the editor view itself, so
the issue continues to appear when using a highlighting theme with
varied font weights.
Fix the issue by applying the same fix in layout_text.
Closes#42297

- Fixed incorrect font weights in editor view when using a highlighting
theme with varying font weights

CLOSES #39042
This is a reopening of #34985+.
_Original descrioption_:
In Wayland, the client implement key repeat themself. In Zed this is
ultimately handled by the gpui crate by inserting a timer source into
the event loop which repeat itself if the key is still held down [1].
But it seems the processing of the repeated key event happen
synchronously inside the timer source handler, meaning the effective
rate become slightly lower (since the repeated timer is scheduled using
the 1/rate as delay).
I measured the event processing time on my laptop and it's typically
around 3ms, but sometimes spiking at 10ms. At low key repeat rates this
is probably not _very_ noticeable. I see the default in Zed is set to a
(measly) 16/s, but I assume most systems will use something closer to
25, which is a 40ms delay. So ~3ms is around 7.5% of the delay. At
higher rate the discrepancy become worse of course.
I can visible notice the spikes, and doing some crude stopwatch
measurements using gedit as a reference I can reproduce around 5-10%
slower rates in Zed.
IMO this is significant enough to warrant improving, especially since
some people can get quite used the repeat rate and might feel something
being "off" in Zed.
~~The suggested fix simply subtract the processing time from the next
delay timer.~~

Release Notes:
- Improved Wayland (Linux) key repeat rate precision
