When impellerc fails with a long shader compilation error, truncate it and output to a file by b-luk · Pull Request #182786 · flutter/flutter

b-luk · 2026-02-23T20:52:09Z

This was suggested in #182400 (comment).
Fixes #182497

impellerc's SkSL validation produces a very long error message consisting of the full SkSL result as well as a potentially long list of errors.

When these are more than a few lines, output a truncated version to the stderr output. If the output was truncated, write the full message to a file in the temporary directory.

Adds a new --verbose flag to impellerc. If this flag is provided, the output is never truncated.

Update shader_compiler.dart to remove the "impellerc stdout" and "impellerc stderr" output from shader_compiler.dart. The output of impellerc is already shown when it is run with _processManager.start(). So printing the output again as part of the ShaderCompilerException message is redundant and adds a lot of clutter.

Before (this is very long):

Code Review

This pull request improves the developer experience by truncating long shader compilation error messages from impellerc and outputting the full error to a separate file. This helps to reduce console clutter while still providing access to the complete error details when needed. The changes are well-implemented across the C++ compiler, the Dart build tools, and their respective tests. I've included one suggestion to refactor a piece of duplicated code in the C++ implementation.

This is looking good. Here's an overview of the high level feedback:

remove unnecessary std::shared_ptr
use absl::Status
unify error storing, we need either verbose or truncated output, not both
switch to writing the verbose log into the temp directory
make the flag that forces the write to stderr

+      output << "\n        " << line;
+      if (++line_index == kVerboseErrorLineThreshold) {


There should be a way to disable truncating with flags so that on CI we never truncate. Maybe there is an existing verbose flag?

I added a --verbose flag to impellerc to make it output untruncated to stderr. This isn't used by CI yet though. I think I'll need to pipe it through shader_compiler.dart and the build system to make CI set it. I'll follow up with this.

Please file an issue.

Thanks for following up. I think this is good. I just have a few notes.

-const std::shared_ptr<Compiler>& CompilerTestBase::GetCompiler() const {
-  return compiler_;
+const Compiler& CompilerTestBase::GetCompiler() const {
+  EXPECT_NE(compiler_, nullptr)


Suggested change

EXPECT_NE(compiler_, nullptr)

ASSERT_NE(compiler_, nullptr)

You want the test to abort if this isn't true, not crash the test runner.

Using ASSERT_NE won't compile because there's no return value for the function.

I changed this to return a pointer instead of a const reference, and I updatedthe test where it's used to ASSERT the return value.

sounds good

…t and output to a file (flutter#182786) This was suggested in https://github.com/flutter/flutter/issues/182400#issuecomment-3916413468. Fixes https://github.com/flutter/flutter/issues/182497 impellerc's SkSL validation produces a very long error message consisting of the full SkSL result as well as a potentially long list of errors. When these are more than a few lines, output a truncated version to the stderr output. If the output was truncated, write the full message to a file in the temporary directory. Adds a new --verbose flag to impellerc. If this flag is provided, the output is never truncated. Update shader_compiler.dart to remove the "impellerc stdout" and "impellerc stderr" output from shader_compiler.dart. The output of impellerc is already shown when it is run with `_processManager.start()`. So printing the output again as part of the `ShaderCompilerException` message is redundant and adds a lot of clutter. <details> <summary> #### Before (this is very long): </summary> ``` ❯ flutter run --local-engine-host host_debug_unopt_arm64 --local-engine host_debug_unopt_arm64 -d mac Launching lib/main.dart on macOS in debug mode...
