Start with cgi_test.go and frankenphp.go, then reproduce the failure using the OSS-Fuzz build_image and build_fuzzers commands in the issue. Remove the benchmark function from cgi_test.go and add the missing os import to frankenphp.go; confirm the fuzz targets compile with the fuzzing build and check_build.

Descrição

bug
What happened?

The FrankenPHP OSS-Fuzz fuzz build fails while compiling the Go fuzz targets. The failure occurs in the fuzzing build, before the fuzzers can be produced. The reported errors include missing references to testing.B in the generated cgi_test.go_fuzz.go file and to os in frankenphp.go. The affected code contains a benchmark function in cgi_test.go:

func BenchmarkSplitRawHeader(b *testing.B) {
    ...
}

This benchmark is not required by the fuzz targets but is included in the fuzzing build transformation. The fuzz build does not provide the benchmark testing context required by this function.

The failure also indicates that frankenphp.go uses the os package without the corresponding import.

The issue can be reproduced with the OSS-Fuzz build command:

python infra/helper.py build_image frankenphp
python infra/helper.py build_fuzzers \
  --sanitizer address \
  --engine libfuzzer \
  --architecture x86_64 \
  frankenphp

Expected behavior: the FrankenPHP fuzz targets should compile successfully.

The fix removes the benchmark function from cgi_test.go and adds the missing os import to frankenphp.go. The patch was successfully verified with the OSS-Fuzz fuzzing build and check_build.

PHP configuration
phpinfo() output 
Not applicable. The failure occurs during the OSS-Fuzz fuzz-target build before a FrankenPHP runtime instance is started, so no phpinfo() output is available.
Relevant log output
Relevant log output 
The fuzz build reported missing references to testing.B in cgi_test.go_fuzz.go and os in frankenphp.go. The build then failed during fuzz-target compilation.
