This patch does the following:
- Updates `flutter_tester` to set up an Impeller rendering context and surface if `--enable-impeller` is set to true, using the Vulkan backend with Swiftshader.
- Updates `run_tests.py` to run all tests except the smoke test (that one really has no rendering impact whatsoever) with and without `--enable-impeller`.
- Updates a few tests to work that were trivial:
- A couple tests needed updated goldens for very minor rendering differences. Filed https://github.com/flutter/flutter/issues/135684 to track using Skia gold for this instead.
- Disabled SKP screenshotting if Impeller is enabled, and updated the test checking that to verify an error is thrown if an SKP is requested.
- The Dart GPU based test now asserts that the gpu context is available if Impeller is enabled, and does not deadlock if run in a single threaded mode.
- We were missing some trace events around `Canvas::SaveLayer` for Impeller as compared to Skia.
- A couple other tests had strict checks about exception messages that are slightly different between Skia and Impeller.
- I've filed bugs for other tests that may require a little more work, and skipped them for now. For FragmentProgram on Vulkan I reused an existing bug.
This is part of my attempt to address https://github.com/flutter/flutter/issues/135693, although @chinmaygarde and I had slightly different ideas about how to do this.
The goals here are:
- Run the Dart unit tests we already have with Impeller enabled.
- Enable running more of the framework tests (including gold tests) with Impeller enabled.
- Run all of these tests via public `dart:ui` API rather than mucking around in C++ internals in the engine.
In https://skia-review.googlesource.com/c/skia/+/742797 Skia refactored
GrBackend* to not require #ifdefs. This changes
callsites in Flutter to use static functions instead of methods that
were conditionally compiled on those classes.
There should be no functional change.
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.
* Revert "Remove GetExternalViewEmbedder from surface (#22272)"
This reverts commit 9dffddd08d0ad6fa7434c5a5bdff87e09da92e57.
* Revert "Rasterizer is initialized with an external view embedder (#22405)"
This reverts commit 417c869d6bcd70ba82fdd6efc8db1efa19fb997c.
This removes most of the remaining FLUTTER_NOLINT comments and opts
these files back into linter enforcement.
I've filed https://github.com/flutter/flutter/issues/68273 to require
that all FLUTTER_NOLINT comments be followed by a GitHub issue URL
describing the problem to be fixed.
Cleans up header order/grouping for consistency: associated header, C/C++ system/standard library headers, library headers, platform-specific #includes.
Adds <cstring> where strlen, memcpy are being used: there are a bunch of places we use them transitively.
Applies linter-required cleanups. Disables linter on one file due to included RapidJson header. See https://github.com/flutter/flutter/issues/65676
This patch does not cover flutter/shell/platform/darwin. There's a separate, slightly more intensive cleanup for those in progress.
This is part of a larger effort to expose the difference between GrDirectContext,
which runs on the GPU thread and can directly perform operations like uploading
textures, and GrRecordingContext, which can only queue up work to be delivered
to the GrDirectContext later.
* Revert "Add flow test fixtures and tests (#13986)"
This reverts commit 32915132bacdfd0d631421b23bb6a6d5db1095ab.
* Revert "Dynamically determine whether to use offscreen surface based on need (#13976)"
This reverts commit a13401ce86b3019c39154d56644b7b9eb4a5bbe5.
With the update to HEAD of the Fuchsia buildtools repo, the new clang
toolchain picked up caused link-time breakage in android x86_64
libFlutter.so builds.
Sample log:
https://build.chromium.org/p/client.flutter/builders/Linux%20Engine/builds/1974/steps/build%20android_debug_x64/logs/stdio
Sample failure:

This reverts commit fecc7aa281821e01037089846744b5331e3cbd22.
* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5
This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb
which disables -Wtautological-constant-compare temporarily until
https://reviews.llvm.org/D39462 lands in clang. This is in line with
Fuchsia's compiler options.
* Apply clang-format diffs
No logical changes. This applies clang-format from the latest Fuchsia
buildtools to the engine codebase.
