hashicorp/nomad: technical due diligence, read from its repository

The median source file here is 81 lines. 52 files exceed 1,000 lines, the largest being 10,968. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

The suite is configured to retry failing tests (e2e/ui/playwright.config.js). A retry turns a flaky test green without saying why it failed, so a green build means the tests passed eventually. Ask how many retries a typical run needs, and which tests need them.

The code is pinned to Node.js 12 (end of life 2022-04-30). None of these receives security fixes any more; the first stopped on 2022-04-30. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

The newest release, v2.0.7, is not on the branch this survey read; the newest release on it is v1.2.6. The shipped product may differ from what this report describes. Survey the release branch too.

1 step pipes a download straight into a shell. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

6 places in product code build SQL by formatting or joining strings rather than passing parameters. In each, what the code shows going in is a table or column name, a constant, or something the line does not show, not a request's value. Ask whether any value reaches these strings, rather than a parameter.

6 of 1,958 locked dependencies match 7 published advisories in OSV, 4 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. None of the high or critical ones is in what the product ships: they are development dependencies.

LICENSE grants BUSL-1.1: source available, not open source; production use restricted until the change date. The reading comes from the licence's own title and clauses. Whether the terms fit the buyer's intended use, and whether any paid licence transfers with the code, is a question for counsel and the licensor.

The root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.
