* Issue SetDrawColorBuffers commands before issuing ClearColor
This is necessary for glClearBuffer calls to work correctly on some machines (e.g. AMD Renoir graphics running on Linux). Without this, glClearBuffer calls are ignored.
* Use clear_buffer_f32_slice instead of gl.clear to suppress WebGL warnings
This fixes the following WebGL warning: "WebGL warning: drawBuffers: `buffers[i]` must be NONE or COLOR_ATTACHMENTi."
When using native OpenGL, it is acceptable to call glDrawBuffers with an array of buffers where i != COLOR_ATTACHMENTi. In WebGL, this is not allowed.
* Run cargo fmt
* Add changes for PR GH-5666 to the CHANGELOG
A `for` loop is less noisy than a `drain`, which requires:
- a `mut` qualifier for a variable whose modified value we never
consult
- a method name appearing mid-line instead of a control structure name
at the front of the line
- a range which is always `..`, establishing no restriction at all
- a closure instead of a block
Structured control flow syntax has a fine pedigree, originating in,
among other places, Dijkstrsa's efforts at designing languages in a
way that made it easier to formally verify programs written in
them (see "A Discipline Of Programming"). There is nothing "more
mathematical" about a method call that takes a closure than a `for`
loop. Since `for_each` is useless unless the closure has side effects,
there's nothing "more functional" about `for_each` here, either.
Obsessive use of `for_each` suggests that the author loves Haskell
without understanding it.
Rename `LifetimeTracker::triage_resources`'s `resources_map` argument
to `suspected_resources`, since this always points to a field of
`LifetimeTracker::suspected_resources`.
In the various `triage_suspected_foo` functions, name the map
`suspected_foos`.
Check whether the resource is abandoned first, since none of the rest
of the work is necessary otherwise.
Rename `non_referenced_resources` to `last_resources`. This function
copes with various senses in which the resource might be referenced or
not. Instead, `last_resources` is the name of the `ActiveSubmission`
member this may point to, which is more specific.
Move the use of `last_resources` immediately after its production.
* Avoid introducing spurious features for optional dependencies
If a feature depends on an optional dependency without using the dep:
prefix, a feature with the same name as the optional dependency is
introduced. This feature almost certainly won't have any effect when
enabled other than increasing compile times and polutes the feature list
shown by cargo add. Consistently use dep: for all optional dependencies
to avoid this problem.
* Add changelog entry
* Clean up weak references to texture views
* add change to CHANGELOG.md
* drop texture view before clean up
* cleanup weak ref to bind groups
* update changelog
* Trim weak backlinks in their holders' triage functions.

Change `Device::untrack` to properly reuse the `ResourceMap` allocated
for prior calls. The prior code tries to do this but always leaves
`Device::temp_suspected` set to a new empty `ResourceMap`, leaving the
previous value to be dropped by `ResourceMap::extend`.
Change `ResourceMap::extend` to take `other` by reference, rather than
taking it by value and dropping it.
Remove unreachable code from `Global::queue_submit` that checks
whether the resources used by the command buffer have a reference
count of one, and adds them to `Device::temp_suspected` if so.
When `queue_submit` is called, all the `Arc`s processed by this code
have a reference count of at least three, even when the user has
dropped the resource:
- `Device::trackers` holds strong references to all the device's
resources.
- `CommandBufferMutable::trackers` holds strong references to all
resources used by the command buffer.
- The `used_resources` methods of the various members of
`CommandBufferMutable::trackers` all return iterators of owned
`Arc`s.
Fortunately, since the `Global::device_drop_foo` methods all add the
`foo` being dropped to `Device::suspected_resources`, and
`LifetimeTracker::triage_suspected` does an adequate job of accounting
for the uninteresting `Arc`s and leaves the resources there until
they're actually dead, things do get cleaned up without the checks in
`Global::queue_submit`.
This allows `Device::temp_suspected` to be private to
`device::resource`, with a sole remaining use in `Device::untrack`.
Fixes#5647.
The lock analyzers in the `wgpu_core::lock` module can be a bit
simpler if they can assume that locks are acquired and released in a
stack-like order: that a guard is only dropped when it is the most
recently acquired lock guard still held. So:
- Change `Device::maintain` to take a `RwLockReadGuard` for the device's
hal fence, rather than just a reference to it.
- Adjust the order in which guards are dropped in `Device::maintain`
and `Queue::submit`.
Fixes#5610.
Rather than implementing `Drop` for all three lock guard types to
restore the lock analysis' per-thread state, let lock guards own
values of a new type, `LockStateGuard`, with the appropriate `Drop`
implementation. This is cleaner and shorter, and helps us implement
`RwLock::downgrade` in a later commit.
Explain more clearly that the `write_buffer`, `write_buffer_with`, and
`write_texture` methods on `wgpu::Queue` do not immediately submit the
transfers for execution. Provide sample code for flushing them.
Use `std::panic::Location` to record the source location of each
`#[gpu_test]` test, and if it fails, include that in the error output.
This is not essential, but it should make working with failures a bit
more comfortable.
This fixes 2 issues:
- we used to index `adjusted_global_expressions` with the handle index of the constant instead of its initializer
- we used to adjust the initializer multiple times if the arena contained multiple `Expression::Constant`s pointing to the same constant
* Fix cts_runner command invocation in readme
* Remove assertDeviceMatch from deno_webgpu in createBindGroup
This should be done as verification in wgpu-core.
* Add device mismatched check to create_buffer_binding
* Extract common logic to create_sampler_binding
* Move common logic to create_texture_binding and add device mismatch check
