# Objective
Constify `Val::resolve` and `BorderRadius::resolve`
# Solution
* Replace uses of `Vec2::min_element` and `Vec2::max_element` with `min`
and `max` called on the components.
* Make `BorderRadius::resolve` and `BorderRadius::resolve_single_corner`
`const`.
* Swap the order of the `bottom_left` and `bottom_right` fields of
`BorderRadius` and `ResolvedBorderRadius` so they match the ccw order
used in the shader and in css.
# Objective
- Enable state scoped entities by default
- Provide a way to disable it when needed

# Objective
- Related to #19024
## Solution
- Use the new `load_shader_library` macro for the shader libraries and
`embedded_asset`/`load_embedded_asset` for the "shader binaries" in
bevy_render.
## Testing
- `animate_shader` example still works
P.S. I don't think this needs a migration guide. Technically users could
be using the `pub` weak handles, but there's no actual good use for
them, so omitting it seems fine. Alternatively, we could mix this in
with the migration guide notes for #19137.
# Objective
Improve the `tab_navigation` example.
## Solution
* Set different `TabIndex`s for the buttons of each group.
* Label each button with its associated `TabIndex`.
* Reduce the code duplication using a loop.
I tried to flatten it further using the new spawning APIs and
`children!` macro but not sure what the current best way to attach the
observers is.
# Objective
Allow creating a new window without it being focused, when `Window`'s
`focused` is `false.
## Solution
Use `winit`'s `WindowBuilder`'s `with_active` method
## Notes
- `winit`'s doc lists [redox's
`Orbital`](https://gitlab.redox-os.org/redox-os/orbital) as an
unsupported platform, but since Bevy doesn't officially support this
platform, I didn't put it in the documentation.
- I only tested on Linux, which is an unsupported platform. I can give
you a test code if you want to test on another platform.
- I initially put a line
[here](https://github.com/bevyengine/bevy/blob/v0.11.0/crates/bevy_winit/src/system.rs#L72)
to set the Bevy `Window`'s `focused` to `winit_window.has_focus()` after
window creation to avoid the case where `with_active` is not supported,
the window is spawned focused, no `WindowFocused` event is triggered,
and Bevy `Window` would be desynced from winit's window. But after
testing on Linux (which doesn't support `with_active`) it seems like at
that point `has_focus` returns `false` and the event is triggered, so I
removed it. Do you think I should add it back to be safe?
## Changelog
- A new unfocused `Window` can be created by setting `focused` to
`false`.
## Migration Guide
- If a `Window` is spawned with `focused` set to `false`, it will now
start not focused on supported platforms.

# Objective
cargo update was required to build because into_values was added in a
patch version
## Solution
Depend on the new patch
## Testing
Builds locally now
# Objective
Fixes#17983
## Solution
Implemented a basic `Dir4` struct with methods similar to `Dir3` and
`Dir2`.
## Testing
- Did you test these changes? If so, how?
Added unit tests that follow the same pattern of the other Dir structs.
- Are there any parts that need more testing?
Since the other Dir structs use rotations to test renormalization and I
have been following them as a pattern for the Dir4 struct I haven't
implemented a test to cover renormalization of Dir4's.
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
Use Dir4 in the wild.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
N/A (Tested on Linux/X11 but it shouldn't be a problem)
# Objective
Fixes#19156
## Solution
There was a call to sort by `TabIndex` after iterating through all the
`TabGroup`s. Simply removing that line of code made the new test case
pass (navigating through `TabIndex` within different `TabGroup`s and
kept everything else working as expected as far as I can tell.
I went ahead and broke the `focusable` vec down into per-group vecs that
get sorted by `TabIndex` and appended to the main vec in group sorted
order to maintain the sorting that was being done before, but respecting
the `TabGroup` sorting that was missing in the issue that this PR
addresses.
## Testing
I added a new unit test that reproduced the issue outlined above that
will run in CI. This test was failing before deleting the sort, and now
both unit tests are passing.
# Objective
Fixes#18790.
Simpler alternative to #19195.
## Solution
As suggested by @PixelDust22, simply avoid overwriting the pass if the
schedule already has auto sync points enabled.
Leave pass logic untouched.
It still is probably a bad idea to add systems/set configs before
changing the build settings, but that is not important as long there are
no more complex build passes.
## Testing
Added a test.

[Explanation](https://bevyengine.org/learn/contribute/helping-out/explaining-examples/)
for the 2d shapes example, taken from the original HackMD document and
edited a bit.
This example is a strange one, it's eye-catching mostly because it's the
first example (at time of writing) in the examples page. That being
said, the example does a decent amount of teaching utility to it: we can
explain the bevy math-shape to mesh pipeline, which illuminates a way of
transforming one form of data (abstract, mathematical shape
descriptions) into another (meshes) which may be novel or inspirational
to some users.

> [!important]
> To **maintainers**: we should wait to merge this one in until after
#18944 lands so that cherry-picking the latter for 0.16.1 is simpler.
# Objective
The `std` module is where we implement the reflection traits for types
that are exported from `std` (including `core` and `alloc`). Over time,
this file has grown increasingly large, making it difficult to navigate
and a pain point for merge conflicts.
The goal of this PR is to break up the module into smaller chunks.
## Solution
The `std` module has been split into many submodules:
- `alloc`
- `bevy_platform`
- `core`
- `std`
Each of these new modules is comprised of submodules that closely
resemble the actual module. For example, the impls for
`::alloc::vec::Vec` have been moved to
`bevy_reflect::impls::alloc::vec::Vec`.
Some liberties were taken. For example, `Cow<'static, Path>` was kept in
`bevy_reflect::impls::std::path` rather than
`bevy_reflect::impls::alloc::borrow`.
You may ask: _Isn't this a little overkill? Why does the one-line impl
for `TypeId` need its own file?_
And yes, it is partly overkill. But the benefit with this approach is
that where an `std`-related type should live is mostly unambiguous. If
we wanted to reflect `::core::net::Ipv4Addr`, it's very clear that it
should be done in `bevy_reflect::impls::core::net`.
We can discuss better ways of breaking this up if people have other
ideas or opinions, but I think this is a pretty straightforward way of
doing it.
### Note to Reviewers
The code is pretty much copy-paste from the mega module to the new
submodules. It's probably best to focus efforts on reviewing the general
module structure, as well as maybe which impls are included where.
You _can_ review the code contained within each impl, but I promise you
the only thing I touched were the paths in the macros so they could be
more hygienic :)
## Testing
You can just check that everything compiles still:
```
cargo check -p bevy_reflect --tests
```
# Objective
- The tigger_screenshots system gets added in `.build()` but relies on a
resource that is only inserted in `.finish()`
- This isn't a bug for most users, but when doing headless mode testing
it can technically work without ever calling `.finish()` and did work
before bevy 0.15 but while migrating my work codebase I had an issue of
test failing because of this
## Solution
- Move the trigger_screenshots system to `.finish()`
## Testing
- I ran the screenshot example and it worked as expected
# Objective
- Allow compressed image formats to be used with `ImagePlugin` and
`GltfPlugin` in cases where there is no `RenderDevice` resource. (For
example, when using a custom render backend)
## Solution
- Define a `CompressedImageFormatSupport` component that allows the user
to explicitly determine which formats are supported.
~~Not sure if this is the best solution. Alternatively, I considered
initializing CompressedImageFormatSupport from render device features
separately, it would need to run after the render device is initialized
but before `ImagePlugin` and `GltfPlugin` finish. Not sure where the
best place for that to happen would be.~~
Update: decided on going with @greeble-dev solution: defining the
`CompressedImageFormatSupport` resource in `bevy_image`, but letting
`bevy_render` register the resource value.
## produce a DragEnter event when reentering the dragged entity
when making a piano, i want dragging across the keys to trigger the
notes of each key, but currently if i drag out of a key, then back to
it, this will not work since the dragged entity gets filtered out
## Solution
- make DragEnter event work whenever there's an entry. if the user wants
to ignore the dragged entity they can compare `target` and `dragged`
## Testing
- tested this with a modified version of the 2d_shapes example. i added
an observer to the entities: (and added mesh picking plugin)
```rust
.observe(|t: Trigger<Pointer<DragEnter>>| {
info!("entered {}, started from {}", t.target(), t.dragged);
}
```
- i'm not sure if other things need more testing, or if this is wrong
completely and breaks other things i don't know of!

# Objective
- Allow users to get the playback position of playing audio.

## Testing
- Updated `audio_control` example to show playback position
# Objective
- Update AccessKit crates to their latest versions.

## Solution
- Only modifying Cargo.toml files is needed, few changes under the hood

## Testing
- I ran the tab_navigation example on Windows 11.
# Objective
Since #18704 is done, we can track the length of unique entity row
collections with only a `u32` and identify an index within that
collection with only a `NonMaxU32`. This leaves an opportunity for
performance improvements.
## Solution
- Use `EntityRow` in sparse sets.
- Change table, entity, and query lengths to be `u32` instead of
`usize`.
- Keep `batching` module `usize` based since that is reused for events,
which may exceed `u32::MAX`.
- Change according `Range<usize>` to `Range<u32>`. This is more
efficient and helps justify safety.
- Change `ArchetypeRow` and `TableRow` to wrap `NonMaxU32` instead of
`u32`.
Justifying `NonMaxU32::new_unchecked` everywhere is predicated on this
safety comment in `Entities::set`: "`location` must be valid for the
entity at `index` or immediately made valid afterwards before handing
control to unknown code." This ensures no entity is in two table rows
for example. That fact is used to argue uniqueness of the entity rows in
each table, archetype, sparse set, query, etc. So if there's no
duplicates, and a maximum total entities of `u32::MAX` none of the
corresponding row ids / indexes can exceed `NonMaxU32`.

# Objective
`Image::resize` currently prints a warning when resizing an
uninitialized `Image`, even though the resizing works correctly. For
[code](c92f14c9e7/crates/bevy_ui/src/widget/viewport.rs (L175-L179))
that doesn't care about whether the image is initialized CP-side, this
is inconvenient and unnecessary.
# Objective
Ran into a situation where I need to compare two image samplers. My
current workaround is to compare the `Debug` outputs
## Solution
Derive `PartialEq` on `ImageSampler` and structs in its fields.
## Testing
Full CI passed.
# Objective
The new viewport example allocates a texture in main memory, even though
it's only needed on the GPU. Also fix an unnecessary warning when a
viewport's texture doesn't exist CPU-side.
## Testing
Run the `viewport_node` example.
# Objective
allow specifying the left/top/right/bottom border colors separately for
ui elements
fixes#14773
## Solution
- change `BorderColor` to
```rs
pub struct BorderColor {
pub left: Color,
pub top: Color,
pub right: Color,
pub bottom: Color,
}
```
- generate one ui node per distinct border color, set flags for the
active borders
- render only the active borders
i chose to do this rather than adding multiple colors to the
ExtractedUiNode in order to minimize the impact for the common case
where all border colors are the same.
## Testing
modified the `borders` example to use separate colors:
the behaviour is a bit weird but it mirrors html/css border behaviour.
---
## Migration:
To keep the existing behaviour, just change `BorderColor(color)` into
`BorderColor::all(color)`.

# Objective
- Currently, the error span for `get_struct_field` when encountering an
enum or union points to the macro invocation, rather than the `enum` or
`union` token. It also doesn't mention which macro reported the error.

- Report the correct error span
- Add parameter for passing in the name of the macro invocation
## Testing
Bevy compiles fine with this change

// before
let fields = get_struct_fields(&ast.data);
// after
let fields = get_struct_fields(&ast.data, "derive(Bundle)");

Hiya!
# Objective
- Remove upcasting methods that are no longer necessary since Rust 1.86.
- Cleanup the interned label code.
## Notes
- I didn't try to remove the upcasting methods from `bevy_reflect`, as
there appears to be some complexity related to remote type reflection.
- There are likely some other upcasting methods floating around.
## Testing
I ran the `breakout` example to check that the hashing/eq
implementations of the labels are still correct.

similar to https://github.com/bevyengine/bevy/pull/12030
# Objective
`bevy_mod_debugdump` uses the `SystemTypeSet::system_type` to look up
constrains like `(system_1, system_2.after(system_1))`. For that it
needs to find the type id in `schedule.graph().systems()`
Now with systems being wrapped in an `InfallibleSystemWrapper` this
association was no longer possible.
## Solution
By forwarding the type id in `InfallibleSystemWrapper`,
`bevy_mod_debugdump` can resolve the dependencies as before, and the
wrapper is an unnoticable implementation detail.
## Testing
- `cargo test -p bevy_ecs`
I'm not sure what exactly could break otherwise.
As I run bevy in a apx container, the default dependencies are bare
minimum.. because of which I was able to find the explicit dependencies
required for bevy. 👍 the same shall also be applicable for the other
distributions but I will have to figure out explicit ones for them and
might open a PR for them later.
# Objective
- Have explicit dependencies listed for a bare minimum system /
container
## Solution
- Running bevy in a bare minimum apx / distrobox container.

# Objective
- Fixes#18869.
## Solution
The issue was the `?` after a `Result` raising the error, instead of
treating it.
Instead it is handled with `ok`, `and_then`, `map` ...
_Edit: I added the following logic._
On `bevy/query` remote requests, when `strict` is false:
- Unregistered components in `option` and `without` are ignored.
- Unregistered components in `has` are considered absent from the
entity.
- Unregistered components in `components` and `with` result in an empty
response since they specify hard requirements.
I made the `get_component_ids` function return a
`AnyhowResult<(Vec<(TypeId, ComponentId)>, Vec<String>)>` instead of the
previous `AnyhowResult<Vec<(TypeId, ComponentId)>>`; that is I added the
list of unregistered components.
## Testing
I tested changes using the same procedure as in the linked issue:
```sh
cargo run --example server --features="bevy_remote"
```
In another terminal:
```sh
# Not strict:
$ curl -X POST http://localhost:15702 -H "Content-Type: application/json" -d '{ "jsonrpc": "2.0", "method": "bevy/query", "id": 0, "params": { "data": { "components": [ "foo::bar::MyComponent" ] } } }'
{"jsonrpc":"2.0","id":0,"result":[]}
# Strict:
$ curl -X POST http://localhost:15702 -H "Content-Type: application/json" -d '{ "jsonrpc": "2.0", "method": "bevy/query", "id": 0, "params": { "data": { "components": [ "foo::bar::MyComponent" ] }, "strict": true } }'
{"jsonrpc":"2.0","id":0,"error":{"code":-23402,"message":"Component `foo::bar::MyComponent` isn't registered or used in the world"}}

# Objective
It's not possible atm for third-party crates to create their own text
systems that use the existing cosmic-text `FontSystem` and font atlases.
## Solution
Make `FontFaceInfo`, `TextPipeline::map_handle_to_font_id`, and
`load_font_fontdb` public so third-party crates can access and update
the existing font atlases
# Objective
Accessibility features don't work with the UI `button` example because
`InputFocus` must be set for the accessibility systems to recognise the
button.
Fixes#18760
## Solution
* Set the button entity as the `InputFocus` when it is hovered or
pressed.
* Call `set_changed` on the `Button` component when the button's state
changes to hovered or pressed (the accessibility system's only update
the button's state when the `Button` component is marked as changed).
## Testing
Install NVDA, it should say "hover" when the button is hovered and
"pressed" when the button is pressed.
The bounds of the accessibility node are reported incorrectly. I thought
we fixed this, I'll take another look at it. It's not a problem with
this PR.
