This allows Fuchsia components executed by the Flutter runner to
specify a directory containing assets if they wish to store assets
separate from program data. This is specified in the program metadata
field within the component's specification with the new "assets"
attribute. If this attribute is absent, assets are loaded relative to
the path specified in the "data" attribute as before.
This is useful in the short term to use a location in the package where
we can store small files more efficiently. It is also potentially
useful longer term to enforce a stronger separatation between
executable program data and non-executable assets.
This commit adds some basic unit testing for the data parsing to the
flutter_runner_tests suite.
This format is preferred on some hardware. Also explicitly
specify color space when creating the skia surface.

* Update flutter to use new skia flushing/submit api
This has no functional change, just moving to the new api calls.
* Update vulkan_swapchain.cc
* Update embedder_external_view_embedder.cc
* Revert "Do not register UI-related native functions in secondary isolates (#6401)"
This reverts commit 69ae5694de54d2a163743dcec727fcea1c7bc8e1 as it doesn't work when root and secondary isolates run in the same isolate group.
* Confirm it is root isolate that makes UI native calls.
* Fix format, UIDartState reference from Fuchsia source
* No UI isolate check for fuchsia calls
* Fix typo. Remove redundant runtime calls
In order to better support different products on Fuchsia, we should
change performance-sensitive attributes based on config files passed in.
This change does so for `vsync_offset`.
This functionality is added in issue #41523. Allows runners to request
the singleton instance of `sys::ComponentContext`, while it remains also
accessible to component-specific code that does not have direct access
to top-level objects.
Fixes#41523
The raster cache is critical for good performance. This
enables the cache and provides a GrContext to ScopedFrame
instances so the cache can be efficiently populated.
Small increase in peak GPU memory usage is expected from
this change. Otherwise, no change in behavior expected.

16 MiB -> 28 MiB
Same size as what would be used on a 1024x600 display if we
allowed the common engine code to adjust this.

Since the trace provider hasn't been created yet, it is not possible to
trace the creation of a trace provider using a TRACE_DURATION event (the
trace enabled and category check will always fail). While this isn't
causing any urgent problems, remove it to set a good example for other
clients of tracing that might happen to reference this code.
This PR touches variable names, class names, and file names so it's significantly more risky than its predecessor https://github.com/flutter/engine/pull/17329
Due to file name changes, this PR is expected to change the license files.
We haven't rename `shell/gpu` to `shell/raster` yet. It should be optional but I think it's better to have `raster_surface_software.cc` than `gpu_surface_software.cc`.
close() returns a nonzero in case of an error. Old code had it log
only when *no* error happens on close, which is exactly the opposite
of what we want.
On Fuchsia, we can now get executable VMOs from trusted backing
filesystems. This allows us to remove the use of replace_as_executable
in favor of opening files with `fdio_open_fd_at` with the
`OPEN_RIGHT_EXECUTABLE` flag and getting VMOs by calling
`fdio_get_vmo_exec`.
By moving the responsibility for executability into the filesystem, we
are able to remove `deprecated-ambient-replace-as-executable` from
component manifests for non-JIT runners (the JIT runners still call
replace_as_executable in Dart's allocator). It wasn't abundantly clear
whether .cmx files for tests were used purely in AOT runtime
environments or also saw JIT usage, so I left those as-is.
For context: this is a second attempt at #16690, which was reverted
because it broke the Dart JIT runner. The primary difference is that
this time around, we correctly handle absolute vs relative paths,
depending on whether library loading bottoms out in `fdio_open_fd` or
`fdio_open_fd_at`. I've added additional assertions to help ensure any
new usages use the correct shape of path.
Testing: I verified locally that the flutter product runner works on
Astro, and also successfully ran the Dart JIT example test (which was
the thing blocking the google3 roll with the previous attempt at this
patchset).

* [fuchsia] Add labels to Scenic nodes.
* [fuchsia] Skip creating Scenic nodes for identity Transforms.
* [fuchsia] Assign elevation to Scenic nodes based on paint order.
* [fuchsia] Create Scenic OpacityNodes at leaf nodes.
* [fuchsia] Composite PhysicalShapeLayers using Skia, except when they need to float above child views.
In that case, they will still need to be pulled
into separate Scenic nodes to be composited on top
of the child view[s].
* [fuchsia] Add tests for Fuchsia-specific layer behavior.
Inspect commands going to Scenic and make sure
they match what is expected.
Also, restructure code to need less member variables,
and other cleanups based on review feedback.

The FIDL interface `fuchsia.timezone.Timezone` does not exist for quite
a while now. Instead, a transitional `fuchsia.timezone.Timezone` should
be used.

This was already enabled by-default in AOT mode in [0] - which made the
gen_snapshot invocations use "--lazy-async-stacks --no-causal-async-stacks".

* Chaged tests to set node flags using bitwise-or instead of addition.
* Address bug in update size arithmetic.
* Fixes issue in TruncatesLargeValue unit test causing unexpected deletes.
* Fixes expected number of updates in BatchesLargeMessages unit test to reflect expected values now that node states are populated.
