📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a Bash-based CockroachDB benchmark wrapper. It manages tools and cluster lifecycle, runs configured workloads, validates results, aggregates metrics, documents operation, adds platform dependencies, and includes GPLv2 licensing. ChangesCockroachDB benchmark execution
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The wrapper can treat failed downloads, failed workloads, and invalid results as successful benchmark data, producing false reports and masking setup or execution failures. Merge should wait until these failure paths stop the run before aggregation. Sequence Diagram(s)sequenceDiagram

The tarball is fetched over HTTPS but never checksummed against CockroachDB's published SHA256SUMS before extraction and execution. Worth adding a checksum check as a supply-chain hardening measure.

Inline comments:
In `@cockroachdb/cockroachdb_run`:
- Around line 167-171: Update the cached-install logic around cockroach_dir so
the cache is version-specific and cannot reuse a CockroachDB build created for a
different --cockroach_version. Incorporate the requested version into the
installation path or validate the existing installation’s version before
returning, while preserving reuse when the cached version matches.
- Around line 350-380: Adjust the averaging logic surrounding the iteration loop
to track the count of successfully parsed rval values, incrementing it only
after a valid parse. Use that count for samples, including the trimmed-mean
calculation and its high/low exclusions, while preserving the existing behavior
when all iterations parse successfully.
- Around line 310-317: Update both test_header_info invocations in the
CockroachDB result-generation flow to include Start_Date and End_Date in the
--field_header list, preserving the existing fields and ordering otherwise.
Ensure the generated CSV header matches the start_time and end_time result
columns consumed by csv_to_json and Cockroachdb_Results.
In `@license`:
- Around line 1-17: Rename the lowercase license header-notice template to a
distinct, non-colliding filename such as HEADER_NOTICE, while preserving its
contents and updating any references to the current license filename. Keep the
existing full LICENSE file unchanged.

- Around line 284-292: Update the workload result handling around the cockroach
workload command and ops_sec parsing so any nonzero workload exit or missing
parsed throughput terminates with an invalid-data error instead of recording
ops_sec=0 and continuing. Preserve normal result processing only when the
command succeeds and ops_sec is parsed successfully.
- Around line 194-198: Update the download fallback in the CockroachDB
installation flow to use curl’s HTTP-failure option so 4xx/5xx responses are
rejected, then check the extraction tar command and subsequent mv command and
terminate through the existing error path if either fails. Preserve the existing
