DART CI/CD Troubleshooting

Load this skill when debugging CI failures or working with GitHub Actions.

When the failing claim depends on model/scene structure, physics behavior, or OSG output, also load dart-verify-sim and reproduce it with a text oracle plus assessed visual evidence. Document a visual exception when OSG/Xvfb is unavailable or not applicable in the failing environment.

Quick Commands

# Monitor PR checks
gh pr checks <PR_NUMBER>
gh pr view <PR_NUMBER> --json headRefOid,mergeStateStatus,statusCheckRollup

# View run details
gh run list --branch <BRANCH> -e pull_request -L 20
gh run view <RUN_ID> --json status,conclusion,url

# Debug failures
gh run view <RUN_ID> --job <JOB_ID> --log-failed
gh run view <RUN_ID> --json jobs --jq '.jobs[] | {name, databaseId}'

# Rerun failed jobs only after explicit maintainer/user approval
gh run rerun <RUN_ID> --failed
gh run rerun <RUN_ID> --job <DATABASE_ID>

Common Failure Modes

| Failure Type | Solution | | -------------------- | -------------------------------------------------------- | | Formatting fails | pixi run lint; push only after approval | | Codecov patch fails | Add tests for uncovered lines | | FreeBSD RTTI fails | Use type enums + static_cast instead of dynamic_cast | | macOS ARM64 SEGFAULT | Replace alloca()/VLAs with std::vector<T> | | RTD build fails | Use defensive .get(key, default) patterns | | gz-physics fails | Reproduce with pixi run -e gazebo test-gz |

Workflow Architecture

The CI workflows that a failing PR check belongs to (full 12-workflow index: docs/onboarding/ci-cd.md § "Workflow Index"):

| Workflow | Purpose | Platforms | | ------------------- | -------------------------------------- | ---------- | | ci_ubuntu.yml | AI checks, lint, build, test, coverage | Ubuntu | | ci_macos.yml | Lint, build, test | macOS | | ci_windows.yml | Lint, build, test | Windows | | ci_freebsd.yml | Build + test (VM) | FreeBSD | | ci_simd.yml | SIMD x86 instruction-level matrix | Ubuntu x86_64 | | ci_toolchain.yml | Alternate toolchain build + test | Ubuntu | | ci_gz_physics.yml | Gazebo integration | Ubuntu | | api_doc.yml | Doxygen API docs build | Ubuntu |

Downstream Compatibility Policy

Package, exported-target, collision, constraint, and dependency changes can affect Gazebo/gz-physics even when local unit tests pass. Reproduce those failures with the Gazebo Pixi environment when practical: pixi run -e gazebo test-gz.

Fast Iteration Loop

  1. Identify failing step from job logs
  2. Reproduce locally with same build toggles
  3. Fix the smallest failing test
  4. Push only after explicit maintainer/user approval, then monitor: gh run view <RUN_ID> --json status,conclusion,url

Caching And Duration

Treat the current run and job logs as authoritative. Inspect cache restore/save steps and job timestamps before changing a key; do not rely on fixed duration or cache-speed estimates in this skill.
