Enabled some disabled impeller fragment shader dart tests by gaaclarke · Pull Request #180759 · flutter/flutter

gaaclarke · 2026-01-09T17:59:43Z

Instead of having a short circuit in a long function we instead sort skia only tests into their own function. I've also enabled all the tests that pass.

test exempt: is test

Code Review

This pull request enables several previously disabled Impeller fragment shader tests by refactoring fragment_shader_test.dart. The changes also include simplifying the shader build files and updating some shaders to be compatible with Impeller. While the refactoring is mostly correct, I've found a critical issue where some Impeller-only tests have been moved to a Skia-only section, effectively disabling them. This needs to be addressed to ensure the tests run as intended.

One sec, going to clean this up more. Bot made a good point.

gaaclarke · 2026-01-09T18:38:05Z

Okay, that's much better. I've introduce _runSkiaTest and _runImpellerTest

walley892

I kind of dislike having all of our test fixtures in one build rule and all of the shader tests (largely) in one file. As we add more features to fragment shaders, we should consider breaking things up for maintainability. Not something that needs to be fixed now, though.

Hmm, not sure why linux_unopt failed with now warning. It ran fine locally for me on linux. I'll try rerunning them.

A reason for requesting a revert of flutter/flutter/180759 could
not be found or the reason was not properly formatted. Begin a comment with 'Reason for revert:' to tell the bot why
this issue is being reverted.

jason-simmons · 2026-01-10T00:15:35Z

Reason for revert:
Flakes in fragment_shader_test.dart are happening on LUCI after this PR.

I can reproduce these flakes in my local Linux cloud VM environment.

gaaclarke · 2026-01-10T00:18:00Z

@jason-simmons can you just disable the ones that are flaking? Otherwise can you list them so I can disable them in the reland?

Before the weekend I'd prefer to revert and get the tree green. We can do further investigation next week.

gaaclarke · 2026-01-10T00:22:13Z

@jason-simmons okay, can you link to the flakes so I know where to start looking?

Found them, the look similar to the one I saw above where no output is printed at all:

gaaclarke · 2026-01-10T00:34:01Z

I ran them about 20 times on my cloudtop and I couldn't reproduce it. @jason-simmons were you using ./testing/run_tests.py --type=dart --dart-filter=fragment_shader_test.dart --variant host_debug_unopt to repro or did you have to run all the tests to make it happen?

I think the no output in the failures is a mixmatch between async and non async closures. I can probably fix that.

Nevermind, i got one!

The test still doesn't work on Metal, but this PR fixes it for Vulkan.

Vec3 uniforms on the metal backend are vec4-aligned. This PR accounts for that padding. --------- Co-authored-by: gaaclarke <[email protected]> Fixes getUniformX for Vulkan (flutter#181286) Does what it says on the tin! This PR adds struct member information to the runtime flatbuffer format. This allows dart code to introspect structs at runtime. Also modifies the runtime_stage tests to verify formats for all supported uniform types. Bubbles up struct member information to dart, and uses that information to grab struct members in `getUniformX` related functions. This is necessary on Vulkan because all uniforms are packaged into a single struct. Also re-enables tests - [ ] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [ ] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [ ] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [ ] I signed the [CLA]. - [ ] I listed at least one issue that this PR fixes in the description above. - [ ] I updated/added relevant documentation (doc comments with `///`). - [ ] I added new tests to check the change I am making, or this PR is [test-exempt]. - [ ] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [ ] All existing and new tests are passing. Organize and update fragment shader uniform tests. (flutter#181822) Adds more comprehensive testing for setFloat and getUniform* on fragment shaders. Deletes redundant tests. Fixes getUniformVecX indexing errors. Update web ui fragment shader tests (flutter#181877) Adds a bunch of tests for uniform setting functionality for custom fragment shaders on the web. Deletes redundant tests. Fixes a discovered issue in the uniform offset calculation. We were previously using the `location`, which is the integer offset of the uniform, not the offset in floats.
