# Objective
- As @james7132 said [on
Discord](https://discord.com/channels/691052431525675048/692572690833473578/1224626740773523536),
the `close_on_esc` system is forcing `bevy_window` to depend on
`bevy_input`.
- `close_on_esc` is not likely to be used in production, so it arguably
does not have a place in `bevy_window`.
## Solution
- As suggested by @afonsolage, move `close_on_esc` into
`bevy_dev_tools`.
- Add an example to the documentation too.
- Remove `bevy_window`'s dependency on `bevy_input`.
- Add `bevy_reflect`'s `smol_str` feature to `bevy_window` because it
was implicitly depended upon with `bevy_input` before it was removed.
- Remove any usage of `close_on_esc` from the examples.
- `bevy_dev_tools` is not enabled by default. I personally find it
frustrating to run examples with additional features, so I opted to
remove it entirely.
- This is up for discussion if you have an alternate solution.
---
## Changelog
- Moved `bevy_window::close_on_esc` to `bevy_dev_tools::close_on_esc`.
- Removed usage of `bevy_dev_tools::close_on_esc` from all examples.
## Migration Guide
`bevy_window::close_on_esc` has been moved to
`bevy_dev_tools::close_on_esc`. You will first need to enable
`bevy_dev_tools` as a feature in your `Cargo.toml`:
```toml
[dependencies]
bevy = { version = "0.14", features = ["bevy_dev_tools"] }
```
Finally, modify any imports to use `bevy_dev_tools` instead:
```rust
// Old:
// use bevy:🪟:close_on_esc;
// New:
use bevy::dev_tools::close_on_esc;
App::new()
.add_systems(Update, close_on_esc)
// ...
.run();
```
# Objective
- Since #10811,Bevy uses `assert `in the hot path of iteration. The
`for_each `method has an assert in the outer loop to help the compiler
remove unnecessary branching in the internal loop.
- However , ` for` style iterations do not receive the same treatment.
it still have a branch check in the internal loop, which could
potentially hurt performance.
## Solution
- use `TableRow::from_u32 ` instead of ` TableRow::from_usize` to avoid
unnecessary branch.
Before
After
----------------------------------------------------------------------------
# Objective
`AspectRatio` is a newtype of `f32`, so it can implement basic traits;
`Copy`, `Clone`, `Debug`, `PartialEq` and `PartialOrd`.
## Solution
Derive basic traits for `AspectRatio`.
This is 1 of 5 iterative PR's that affect bevy_ui/layout
---
# Objective
- Extract `UiSurface` into its own file to make diffs in future PR's
easier to digest
## Solution
- Moved `UiSurface` to its own file
# Objective
- Enable stressing of more of the material mesh entity draw code paths
## Solution
- Support generation of a number of different mesh assets from the
built-in primitives, and select randomly from them. This breaks batches
based on different meshes.
- Support disabling automatic batching. This skips the batching cost at
the expense of stressing render pass draw command encoding.
- Support enabling directional light cascaded shadow mapping - this is
commonly a big source of slow down in normal scenes.

This commit makes the following optimizations:
## `MeshPipelineKey`/`BaseMeshPipelineKey` split
`MeshPipelineKey` has been split into `BaseMeshPipelineKey`, which lives
in `bevy_render` and `MeshPipelineKey`, which lives in `bevy_pbr`.
Conceptually, `BaseMeshPipelineKey` is a superclass of
`MeshPipelineKey`. For `BaseMeshPipelineKey`, the bits start at the
highest (most significant) bit and grow downward toward the lowest bit;
for `MeshPipelineKey`, the bits start at the lowest bit and grow upward
toward the highest bit. This prevents them from colliding.
The goal of this is to avoid having to reassemble bits of the pipeline
key for every mesh every frame. Instead, we can just use a bitwise or
operation to combine the pieces that make up a `MeshPipelineKey`.
## `specialize_slow`
Previously, all of `specialize()` was marked as `#[inline]`. This
bloated `queue_material_meshes` unnecessarily, as a large chunk of it
ended up being a slow path that was rarely hit. This commit refactors
the function to move the slow path to `specialize_slow()`.
Together, these two changes shave about 5% off `queue_material_meshes`:
## Migration Guide
- The `primitive_topology` field on `GpuMesh` is now an accessor method:
`GpuMesh::primitive_topology()`.
- For performance reasons, `MeshPipelineKey` has been split into
`BaseMeshPipelineKey`, which lives in `bevy_render`, and
`MeshPipelineKey`, which lives in `bevy_pbr`. These two should be
combined with bitwise-or to produce the final `MeshPipelineKey`.
# Objective
Related to #10572
Allow the `Annulus` primitive to be meshed.
## Solution
We introduce a `Meshable` structure, `AnnulusMeshBuilder`, which allows
the `Annulus` primitive to be meshed, leaving optional configuration of
the number of angular sudivisions to the user. Here is a picture of the
annulus's UV-mapping:
<img width="1440" alt="Screenshot 2024-03-26 at 10 39 48 AM"
src="https://github.com/bevyengine/bevy/assets/2975848/b170291d-cba7-441b-90ee-2ad6841eaedb">
Other features are essentially identical to the implementations for
`Circle`/`Ellipse`.
---
## Changelog
- Introduced `AnnulusMeshBuilder`
- Implemented `Meshable` for `Annulus` with `Output =
AnnulusMeshBuilder`
- Implemented `From<Annulus>` and `From<AnnulusMeshBuilder>` for `Mesh`
- Added `impl_reflect!` declaration for `Annulus` and `Triangle3d` in
`bevy_reflect`
---
## Discussion
### Design considerations
The only interesting wrinkle here is that the existing UV-mapping of
`Ellipse` (and hence of `Circle` and `RegularPolygon`) is non-radial
(it's skew-free, created by situating the mesh in a bounding rectangle),
so the UV-mapping of `Annulus` doesn't limit to that of `Circle` as its
inner radius tends to zero, for instance. I don't see this as a real
issue for `Annulus`, which should almost certainly have this kind of
UV-mapping, but I think we ought to at least consider allowing mesh
configuration for `Circle`/`Ellipse` that performs radial UV-mapping
instead. (In these cases in particular, it would be especially easy,
since we wouldn't need a different parameter set in the builder.)

This PR introduces a new type to the existing math primitives:
- `Tetrahedron`: a polyhedron composed of four triangular faces, six
straight edges, and four vertices
---
## Changelog
### Added

## Solution
Change `process_touch_event` to not update previous_position /
previous_force, and change it once per frame in
`touch_screen_input_system`.
# Objective
Sometimes it's useful to iterate over removed entities. For example, in
my library
[bevy_replicon](https://github.com/projectharmonia/bevy_replicon) I need
it to iterate over all removals to replicate them over the network.
Right now we do lookups, but it would be more convenient and faster to
just iterate over all removals.
## Solution
Add `RemovedComponentEvents::iter`.
---
## Changelog
### Added
- `RemovedComponentEvents::iter` to iterate over all removed components.

# Objective
- There are several redundant imports in the tests and examples that are
not caught by CI because additional flags need to be passed.
## Solution
- Run `cargo check --workspace --tests` and `cargo check --workspace
--examples`, then fix all warnings.
- Add `test-check` to CI, which will be run in the check-compiles job.
This should catch future warnings for tests. Examples are already
checked, but I'm not yet sure why they weren't caught.
## Discussion
- Should the `--tests` and `--examples` flags be added to CI, so this is
caught in the future?
- If so, #12818 will need to be merged first. It was also a warning
raised by checking the examples, but I chose to split off into a
separate PR.

# Objective
There are currently 2 different warning messages that are logged when
resizing on Linux with Nvidia drivers (introduced in
70c69cdd51).
Fixes#12830
## Solution
Generalize both to say:
```Couldn't get swap chain texture. This often happens with the NVIDIA drivers on Linux. It can be safely ignored.```
# Objective
- Since #12453, `DeterministicRenderingConfig` doesn't do anything
## Solution
- Remove it
---
## Migration Guide
- Removed `DeterministicRenderingConfig`. There shouldn't be any z
fighting anymore in the rendering even without setting
`stable_sort_z_fighting`
# Objective
- The `ImePreedit` component from
[`text_input`](50699ecf76/examples/input/text_input.rs (L126-L127))
appears to be unused.
- This was found by running `cargo check --workspace --examples`,
originally as part of #12817.
## Solution
- Remove it :)
# Objective
- The `bundles` parameter in `insert_or_spawn_batch` method has
inconsistent naming with docs (e.g. `bundles_iter`) since #11107.
## Solution
- Replace `bundles` with `bundles_iter`, as `bundles_iter` is more
expressive to its type.
# Objective
Make it easy for crates.io / lib.rs users or automated tools to find the
repository of `bevy_utils_proc_macros`
## Solution
Add the `repository` field to the `Cargo.toml` of
`bevy_utils_proc_macros`
# Objective
This is a necessary precursor to #9122 (this was split from that PR to
reduce the amount of code to review all at once).
Moving `!Send` resource ownership to `App` will make it unambiguously
`!Send`. `SubApp` must be `Send`, so it can't wrap `App`.
## Solution
Refactor `App` and `SubApp` to not have a recursive relationship. Since
`SubApp` no longer wraps `App`, once `!Send` resources are moved out of
`World` and into `App`, `SubApp` will become unambiguously `Send`.
There could be less code duplication between `App` and `SubApp`, but
that would break `App` method chaining.
## Changelog
- `SubApp` no longer wraps `App`.
- `App` fields are no longer publicly accessible.
- `App` can no longer be converted into a `SubApp`.
- Various methods now return references to a `SubApp` instead of an
`App`.
## Migration Guide
- To construct a sub-app, use `SubApp::new()`. `App` can no longer
convert into `SubApp`.
- If you implemented a trait for `App`, you may want to implement it for
`SubApp` as well.
- If you're accessing `app.world` directly, you now have to use
`app.world()` and `app.world_mut()`.
- `App::sub_app` now returns `&SubApp`.
- `App::sub_app_mut` now returns `&mut SubApp`.
- `App::get_sub_app` now returns `Option<&SubApp>.`
- `App::get_sub_app_mut` now returns `Option<&mut SubApp>.`
# Objective
Get an early warning if any new rust lints will break CI. Closes#12625
## Solution
Test the main branch against the Rust beta every week.
## Additional Possibilities
The action currently creates an issue if anything fails. The issue could
use a label like `C-Weekly` but somebody with the ability to create
issue labels would have to add it.
Another possibility would be to use discord webhooks. That would need
somebody with the access to create webhooks on discord and somebody with
the rights to connect that webhook to this repo,
# Objective
Fix crashing on Linux with latest stable Nvidia 550 driver when
resizing. The crash happens at startup with some setups.
Fixes#12199
I think this would be nice to get into 0.13.1
## Solution
Ignore `wgpu::SurfaceError::Outdated` always on this platform+driver.
It looks like Nvidia considered the previous behaviour of not returning
this error a bug:
"Fixed a bug where vkAcquireNextImageKHR() was not returning
VK_ERROR_OUT_OF_DATE_KHR when it should with WSI X11 swapchains"
(https://www.nvidia.com/Download/driverResults.aspx/218826/en-us/)
What I gather from this is that the surface was outdated on previous
drivers too, but they just didn't report it as an error. So behaviour
shouldn't change.
In the issue conversation we experimented with calling `continue` when
this error happens, but I found that it results in some small issues
like bevy_egui scale not updating with the window sometimes. Just doing
nothing seems to work better.

# Objective
For some asset loaders, it can be useful not to read the entire asset
file and just read a specific region of a file. For this, we need a way
to seek at a specific position inside the file
## Solution
I added support for `AsyncSeek` to `Reader`. In my case, I want to only
read a part of a file, and for that I need to seek to a specific point.
## Migration Guide
Every custom reader (which previously only needed the `AsyncRead` trait
implemented) now also needs to implement the `AsyncSeek` trait to add
the seek capability.
# Objective
- Fix#12746
- When users despawn a scene, the `InstanceId` within `spawned_scenes`
and `spawned_dynamic_scenes` is not removed, causing a potential memory
leak
## Solution
- `spawned_scenes` field was never used, and I removed it
- Add a component remove hook for `Handle<DynamicScene>`, and when the
`Handle<DynamicScene>` component is removed, delete the corresponding
`InstanceId` from `spawned_dynamic_scenes`
- Fixes #[12762](https://github.com/bevyengine/bevy/issues/12762).
## Migration Guide
- `Quat` no longer implements `VectorSpace` as unit quaternions don't
actually form proper vector spaces. If you're absolutely certain that
what you're doing is correct, convert the `Quat` into a `Vec4` and
perform the operations before converting back.
# Objective
Other than the exposed functions for reading matched tables and
archetypes, a `QueryState` does not actually need both internal Vecs for
storing matched archetypes and tables. In practice, it will only use one
of the two depending on if it uses dense or archetypal iteration.
Same vein as #12474. The goal is to reduce the memory overhead of using
queries, which Bevy itself, ecosystem plugins, and end users are already
fairly liberally using.
## Solution
Add `StorageId`, which is a union over `TableId` and `ArchetypeId`, and
store only one of the two at runtime. Read the slice as if it was one ID
depending on whether the query is dense or not.
This follows in the same vein as #5085; however, this one directly
impacts heap memory usage at runtime, while #5085 primarily targeted
transient pointers that might not actually exist at runtime.
---
## Changelog
Changed: `QueryState::matched_tables` now returns an iterator instead of
a reference to a slice.
Changed: `QueryState::matched_archetypes` now returns an iterator
instead of a reference to a slice.
## Migration Guide
`QueryState::matched_tables` and `QueryState::matched_archetypes` does
not return a reference to a slice, but an iterator instead. You may need
to use iterator combinators or collect them into a Vec to use it as a
slice.

# Objective
Speed up CPU-side rendering.
## Solution
Use `QueryIter::for_each` and `Mut::bypass_change_detection` to minimize
the total amount of data being written and allow autovectorization to
speed up iteration.
## Performance
Tested against the default `many_cubes`, this results in greater than
15x speed up: 281us -> 18.4us.
As `ViewVisibility::HIDDEN` just wraps false, this is likely just
degenerating into `memset(0)`s on the tables.
Today, we sort all entities added to all phases, even the phases that
don't strictly need sorting, such as the opaque and shadow phases. This
results in a performance loss because our `PhaseItem`s are rather large
in memory, so sorting is slow. Additionally, determining the boundaries
of batches is an O(n) process.
This commit makes Bevy instead applicable place phase items into *bins*
keyed by *bin keys*, which have the invariant that everything in the
same bin is potentially batchable. This makes determining batch
boundaries O(1), because everything in the same bin can be batched.
Instead of sorting each entity, we now sort only the bin keys. This
drops the sorting time to near-zero on workloads with few bins like
`many_cubes --no-frustum-culling`. Memory usage is improved too, with
batch boundaries and dynamic indices now implicit instead of explicit.
The improved memory usage results in a significant win even on
unbatchable workloads like `many_cubes --no-frustum-culling
--vary-material-data-per-instance`, presumably due to cache effects.
Not all phases can be binned; some, such as transparent and transmissive
phases, must still be sorted. To handle this, this commit splits
`PhaseItem` into `BinnedPhaseItem` and `SortedPhaseItem`. Most of the
logic that today deals with `PhaseItem`s has been moved to
`SortedPhaseItem`. `BinnedPhaseItem` has the new logic.
Frame time results (in ms/frame) are as follows:
| Benchmark | `binning` | `main` | Speedup |
| ------------------------ | --------- | ------- | ------- |
| `many_cubes -nfc -vpi` | 232.179 | 312.123 | 34.43% |
| `many_cubes -nfc` | 25.874 | 30.117 | 16.40% |
| `many_foxes` | 3.276 | 3.515 | 7.30% |
(`-nfc` is short for `--no-frustum-culling`; `-vpi` is short for
`--vary-per-instance`.)
---
## Changelog
### Changed
* Render phases have been split into binned and sorted phases. Binned
phases, such as the common opaque phase, achieve improved CPU
performance by avoiding the sorting step.
## Migration Guide
- `PhaseItem` has been split into `BinnedPhaseItem` and
`SortedPhaseItem`. If your code has custom `PhaseItem`s, you will need
to migrate them to one of these two types. `SortedPhaseItem` requires
the fewest code changes, but you may want to pick `BinnedPhaseItem` if
your phase doesn't require sorting, as that enables higher performance.
## Tracy graphs
`many-cubes --no-frustum-culling`, `main` branch:
<img width="1064" alt="Screenshot 2024-03-12 180037"

You can see that `batch_and_prepare_binned_render_phase` is a much
smaller fraction of the time. Zooming in on that function, with yellow
being this branch and red being `main`, we see:
<img width="1064" alt="Screenshot 2024-03-12 175832"

The binning happens in `queue_material_meshes`. Again with yellow being
this branch and red being `main`:

src="https://github.com/bevyengine/bevy/assets/157897/b9b20dc1-11c8-400c-a6cc-1c2e09c1bb96">
We can see that there is a small regression in `queue_material_meshes`
performance, but it's not nearly enough to outweigh the large gains in
`batch_and_prepare_binned_render_phase`.

Created soundtrack example, fade-in and fade-out features, added new
assets, and updated credits.
# Objective
- Fixes#12651
## Solution
- Created a resource to hold the track list.
- The audio assets are then loaded by the asset server and added to the
track list.
- Once the game is in a specific state, an `AudioBundle` is spawned and
plays the appropriate track.
- The audio volume starts at zero and is then incremented gradually
until it reaches full volume.
- Once the game state changes, the current track fades out, and a new
one fades in at the same time, offering a relatively seamless
transition.
- Once a track is completely faded out, it is despawned from the app.
- Game state changes are simulated through a `Timer` for simplicity.
- Track change system is only run if there is a change in the
`GameState` resource.
- All tracks are used according to their respective licenses.

# Objective
- Primitive meshing is suboptimal
- Improve primitive meshing
## Solution
- Add primitive meshing benchmark
- Allows measuring future improvements
---
First of a few PRs to refactor and improve primitive meshing.
This commit changes the `StandardMaterialKey` to be based on a set of
bitflags instead of a structure. We hash it every frame for every mesh,
and `#[derive(Hash)]` doesn't generate particularly efficient code for
large structures full of small types. Packing it into a single `u64`
therefore results in a roughly 10% speedup in `queue_material_meshes` on
`many_cubes --no-frustum-culling`.
# Objective
Wireframes are currently supported for 3D meshes using the
`WireframePlugin` in `bevy_pbr`. This PR adds the same functionality for
2D meshes.
Closes#5881.
## Solution
Since there's no easy way to share material implementations between 2D,
3D, and UI, this is mostly a straight copy and rename from the original
plugin into `bevy_sprite`.

# Objective
- Allow cloning `WinitSettings`. I use this in

## Changelog
- Added `Clone` to `WinitSettings`.
# Objective
- Reduce the size of `create_windows` and isolate accessibility setup
logic.
## Solution
- Move accessibility setup for new windows to the `accessibility`
module.
## Comments
This is a small refactor, no behavior changes.
# Objective
- Disabling some plugins causes a crash due to ambiguities relying in
feature flags and not checking if both plugins are enabled causing code
like this to crash:
`app.add_plugins(DefaultPlugins.build().disable::<AnimationPlugin>())`
## Solution
- Check if plugins were added before ambiguities.
- Move bevy_gizmos ambiguities from bevy_internal to bevy_gizmos since
they already depend on them.
# Objective
Fixes#12752. Fixes#12750. Document the runtime complexity of all of
the `O(1)` operations on the individual APIs.
## Solution
* Mirror `Query::contains` onto `QueryState::contains`
* Make `QueryState::as_nop` pub(crate)
* Make `NopWorldQuery` pub(crate)
* Document all of the O(1) operations on Query and QueryState.
# Objective
Fixes#12727. All parts that `PersistentGpuBuffer` interact with should
be 100% safe both on the CPU and the GPU: `Queue::write_buffer_with`
zeroes out the slice being written to and when uploading to the GPU, and
all slice writes are bounds checked on the CPU side.
## Solution
Make `PersistentGpuBufferable` a safe trait. Enforce it's correct
implementation via assertions. Re-enable `forbid(unsafe_code)` on
`bevy_pbr`.
# Objective
- A scene usually gets created using the `SceneBundle` or
`DynamicSceneBundle`. This means that the scene's entities get added as
children of the root entity (the entity on which the `SceneBundle` gets
added)
- When the scene gets deleted using the `SceneSpawner`, the scene's
entities are deleted, but the `Children` component of the root entity
doesn't get updated. This means that the hierarchy becomes unsound, with
Children linking to non-existing components.
## Solution
- Update the `despawn_sync` logic to also update the `Children` from any
parents of the scene, if there are any
- Adds a test where a Scene gets despawned and checks for dangling
Children references on the parent. The test fails on `main` but works
here.
## Alternative implementations
- One option could be to add a `parent: Option<Entity>` on the
[InstanceInfo](df15cd7dcc/crates/bevy_scene/src/scene_spawner.rs (L27))
struct that tracks if the SceneInstance was added as a child of a root
entity
# Objective
When I wrote #12747 I neglected to translate random samples from

actual triangle.

- Copy pasted `bevy_panic_handler`'s lib.rs into a separate module in
`bevy_app` as a `panic_handler.rs` module file and added the
`PanicHandlerPlugin` in lib.rs of `bevy_app`
- added the dependency into `cargo.toml`
## Review notes
- I probably want some feedback if I imported App and Plugin correctly
in `panic_handler.rs` line 10 and 11.
- As of yet I have not deleted `bevy_panic_handler` crate, wanted to get
a check if I added it correctly.
- Once validated that my move was correct, I'll probably have to remove
the panic handler find default plugins which I probably need some help
to find.
- And then remove bevy panic_handler and making sure ci passes.
- This is my first issue for contributing to bevy so let me know if I am
doing anything wrong.
## tools context

# Objective
CI on main has been failing for the following reason:
```
error[E0636]: the feature `doc_auto_cfg` has already been declared
--> src/lib.rs:48:29
|
48 | #![cfg_attr(docsrs, feature(doc_auto_cfg))]
| ^^^^^^^^^^^^
```
## Solution
Remove the redundant attribute.
# Objective
- Avoid unbounded HashMap growth for opening/closing windows.
## Solution
- Remove map entry in `WinitWindows::remove_window`.
## Migration Guide
- `WinitWindows::get_window_entity` now returns `None` after a window is
closed, instead of a dead entity.

## Comments
The comment this PR replaces was added in
https://github.com/bevyengine/bevy/pull/3575. Since `get_window_entity`
now returns an `Entity` instead of a `WindowId`, this no longer seems
useful. Note that `get_window_entity` is only used
[here](56bcbb0975/crates/bevy_winit/src/lib.rs (L436)),
immediately followed by a warning if the entity returned doesn't exist.
# Objective
- Fixes#12677
## Solution
Updated documentation to make it explicit that enabling the appropriate
optional features is required to use the supported audio file format, as
well as provided link to the Bevy docs listing the optional features.

wgpu error: Validation Error
Caused by:
In a RenderPass
note: encoder = `<CommandBuffer-(0, 1, Gl)>`
In a set_push_constant command
Provided push constant is for stage(s) ShaderStages(VERTEX), however the pipeline layout has no push constant range for the stage(s) ShaderStages(VERTEX)
```
## Solution
- Properly declare the push constant as in
