* Implement toGpuImage, a synchronous, GPU-resident version of
Picture.toImage.
This method kicks off asynchronous work on the raster task runner.
If it fails to rasterize, it will synchronously throw later when
the user attempts to draw to a canvas.
This supports several use cases:
- Quickly snapping off an expensive-to-rasterize image for reuse
across multiple frames.
- Applying multi-pass filters to a render target.
This patch amends flutter_tester so that it can produce an image
object, but that image will always be a grey and white four square checkerboard.
Adds support for CanvasKit on Web, which basically already used
this method for its Picture.toImage implementation.
Throws an UnsupportedError for HTML on Web, since any implementation
there would almost certainly be slower than drawPicture.
Roll Swiftshader, ANGLE, and Vulkan deps.
Updates license bot for new locations of licenses and new files
in roll.
Converts unit test harnesses to use SwANGLE, which is the
supported way of using SwiftShader as a software backend for GLES.
Updates goldens due to swiftshader changes.
Fixes up include paths to avoid directly including third_party
code by that name, which is unlikely to work in other build
environments.
Includes upstream patches to ANGLE and SwiftShader to build in our
windows environments, as well as patches to Skia to support
defining the location of VulkanMemoryAllocator and a patch to ANGLE
to support opting into a newer version of VMA.
Merges most (but not all) of the impeller .clang-tidy rules into the
main .clang-tidy config. Merges:
readability-identifier-naming.PrivateMemberSuffix (_)
readability-identifier-naming.EnumConstantPrefix (k)
modernize-use-default-member-init.UseAssignment
Does not merge:
readability-identifier-naming.PublicMethodCase (CamelCase)
readability-identifier-naming.PrivateMethodCase (CamelCase)
These last two are not merged due to the non-trivial number of existing
field accessors that use field_name() methods to directly return
field_name_. While these are permitted by the C++ style guide, we may
want to move to a single, simple rule and name everything in CamelCase.
These can be enabled in a followup patch.
No new tests added, since this change is style-only.
This CL changes the vsync trace name to "VsyncProcessCallback". The
benchmarks in fuchsia currently support "VsyncProcessCallback" and "vsync callback". After this change, support for "vsync callback" can be safely removed from fuchsia benchmarks.
Test: fx test host_x64/knowledge_card_test
Bug: 73367
Previously, using Platform.executable (from dart:io) returned null (if
non-null-by-default was disabled) or threw an exception (if NNBD was
enabled) since we weren't setting it.
We now pass the executable name to Dart during VM startup based on the
first value in the FlutterProjectArgs::command_line_argv array passed to
FlutterEngineRun (or FlutterEngineInitialize) on startup. argv[0] (if
specified) is explicitly documented as being required to be the
executable name in embedder.h. In the case where no argv[0] is
specified, we instead set Platform.executable to "Flutter" in order to
avoid violating the (non-nullable) type annotation on
Platform.executable.
Note that dart::bin::SetExecutableName() does NOT make a copy of the
input string, so that value needs to be available for the entire lifetime
of the VM.
This also adds EmbedderConfigBuilder::SetExecutableName() to support
setting a fake executable name in unittests. By default, we continue to
set the name "embedder_unittest" unless overridden using this method.
