Summary

Same fix as #1069 (install Debian llvm + LLVM_COV/LLVM_PROFDATA so OpenCode coverage-evidence can run cargo-llvm-cov without rustup llvm-tools-preview).

#1069 is stuck: OpenCode Review Dispatch concurrency group for PR 1069 is held by a non-cancellable hung model-pool job (98m+). New dispatches for #1069 stay pending.

This v2 PR uses a new PR number so OpenCode can run on a free concurrency group. Land either #1069 or this PR; close the other.

Test plan

Summary by CodeRabbit

  • 개선 사항
    • 코드 커버리지 도구 환경이 개선되어 LLVM 기반 커버리지 측정이 더욱 안정적으로 실행됩니다.
    • 설치된 LLVM 버전에 맞는 도구를 자동으로 인식하고 표준 경로에서 사용할 수 있습니다.
    • 관련 환경 변수가 설정되지 않은 경우에도 시스템에서 사용 가능한 도구 경로를 자동으로 구성합니다.

The trusted coverage sandbox image ships cargo-llvm-cov but only apt
cargo/rustc without rustup llvm-tools-preview. cargo-llvm-cov then fails
with "failed to find llvm-tools-preview" on Rust workspaces (e.g. TEPP),
blocking OpenCode approval despite green repository CI.

Install the Debian llvm package, symlink llvm-cov/llvm-profdata into PATH,
export LLVM_COV/LLVM_PROFDATA, and teach ensure_rust_toolchain to prefer
those tools when rustup components are absent.

📝 Walkthrough

Walkthrough

커버리지 도구 이미지에 시스템 LLVM 도구를 설치합니다. llvm-covllvm-profdata를 표준 경로에 연결합니다. Rust 커버리지 실행 전에는 비어 있는 LLVM 도구 환경 변수를 시스템 경로로 설정합니다.

Changes

LLVM 커버리지 도구 설정

Layer / File(s) Summary
커버리지 이미지의 LLVM 도구 제공
.github/workflows/opencode-review-dispatch.yml
이미지에 llvm 패키지를 추가합니다. llvm-covllvm-profdata를 검색하고, 없으면 빌드를 실패시킵니다. 발견한 실행 파일을 표준 경로에 연결하고 LLVM_COV, LLVM_PROFDATA를 설정합니다.
Rust 도구 경로 자동 설정
.github/workflows/opencode-review-dispatch.yml
LLVM_COVLLVM_PROFDATA가 비어 있고 시스템 명령을 사용할 수 있으면 해당 실행 파일 경로를 환경 변수에 설정합니다. 기존 값은 유지합니다.

이미지 빌드에서 LLVM 호환성 검사를 추가하세요.

현재 Dockerfile은 llvmrustc 버전을 고정하지 않고 실행 파일의 존재만 확인합니다. 패키지 조합이 변경되면 cargo-llvm-cov가 coverage 데이터를 처리하지 못할 수 있습니다. rustc -vV, llvm-cov --version, llvm-profdata --version의 LLVM 버전을 비교하는 검사를 추가하세요. 검사 스크립트에서는 set -uawk$1$2를 확장하지 않도록 인용 부호를 수정하세요.
