Changes

• Upgrade the bundled Docker judge from go-judge v1.9.4 to v1.14.0. The newer release exposes seccomp and swap-limit status through /config; it also disables swap by default when cgroups and a swap controller are available.
• Only warn that seccomp is disabled when go-judge explicitly reports seccomp: false, avoiding false warnings from older versions that omit this field.
• Clarify that swap limits may not be enforced when go-judge does not report swap limiting as enabled, and retain the memory measurement warning.

Summary by CodeRabbit

• Bug Fixes
  • Runtime checks now warn when seccomp or memory swap limits are not enabled.
  • Non-error version-check messages are logged as warnings; error messages continue to be logged as errors.
• Updates
  • Updated the judge’s sandbox runtime to a newer version. This update is included in the judge Docker image.

Walkthrough

The judge image now downloads go-judge v1.14.0. The version check captures seccomp and memory swap-limit settings and warns when either setting is not exactly true. The daemon logs non-error messages from versionCheck with log.warn; error messages continue to use log.error.

Full details: Title check

Explanation

The title "Warn about missing sandbox safeguards" matches the main change. The sandbox.ts change adds warnings in versionCheck when seccomp or memory swap limits are not reported as exactly true. The daemon.ts change routes non-error version check messages to log.warn. The title is specific and concise, and it names the main purpose of the change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Warning

Some tools did not complete. Review the errors below.

ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

packages/hydrojudge/src/sandbox.ts

ESLint skipped: missing config or dependency (missing-dependency). The ESLint configuration references a package that is not available in the sandbox.

- Line 248: Update the warning passed to reportWarn in the
memorySwapLimitEnabled check to state that swap limits may not be enforced and
memory limits may therefore not restrict swap usage; retain the existing note
about potentially inaccurate memory usage measurements.
- Around line 244-247: Update the seccomp warning condition around
sandboxSeccomp so it warns only when the value is explicitly false; treat an
omitted value as unknown and do not emit the warning for it.
