Research direction

Reproduce the listed cases around GocciaBenchmarkRunner, the --profile and --mode options, host grants, usage-error flags, and GocciaBundler output handling. Treat the bullets as independent fixes and verify each expected exit code, error class, warning, profile total, and output-directory behavior before considering the issue done.

Description

Summary

Smaller CLI, benchmark and profiler issues. Found in the 0.14.0 docs audit.

Current behavior

  • GocciaBenchmarkRunner exits 0 when an input file fails to load.
  • --profile=functions reports an inflated total time (131 s for a run of about 14 ms), likely recursive double-counting.
  • --profile=all --mode=interpreted silently runs bytecode. The mode switch is documented for --profile, but no warning mentions that it overrode an explicit --mode.
  • --profile-format=flamegraph with --profile=opcodes exits 0 and writes an empty file.
  • Shortened IPv4 host literals under a net grant (127.1, 0x7f.0.0.1) fail with TypeError: Failed to resolve host rather than PermissionDenied. They are refused as intended, but with a different error class.
  • Inconsistent exit codes. --host-environment combined with --deterministic, and a bare --allow-import, exit 1, where other usage errors exit 2.
  • GocciaBundler --output=dist/x.gbc fails unless dist/ exists, and the directory-target cases give misleading errors.

Expected behavior

  • A load failure makes the benchmark runner exit non-zero.
  • Profile totals are correct.
  • An explicit --mode either wins or triggers a warning.
  • A flamegraph with no stacks is a usage error.
  • Shortened IPv4 hosts get PermissionDenied.
  • Usage errors consistently exit 2.
  • The bundler creates the output directory or reports clearly that it's missing.
