openfaas/faas: technical due diligence, read from its repository

What Borehole read in openfaas/faas's code and history at eb29c06: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Product & Engineering Maturity

04.5

Effort is shifting from building to rewriting

adequate

Deleted lines per line added rose from 0.62 to 1.29 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.

Evidence
first half 0.62, second half 1.29 (split 2021-11-22)

Security & Reliability Posture

adequate
05.27

The build runs third-party code it does not pin

adequate

4 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. 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.

Evidence
.github/workflows/build.yml:19 — action pinned by tag
.github/workflows/build.yml:21 — action pinned by tag
05.26

1 locked dependency has published vulnerabilities

adequate

1 of 29 locked dependencies match 1 published advisories in OSV. 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.

Evidence
gateway/go.mod — github.com/docker/distribution v2.8.3+incompatible: GHSA-685w-q87j-wqw3 (moderate)
05.60

Relicensed: MIT → EULA AND MIT (2024-03-02)

adequate

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.

Evidence
LICENSE — MIT from 2017-01-23
EULA.md — EULA AND MIT from 2024-03-02
05.61

Part of the code is under a separate licence: pro/

adequate

A directory named for a paid edition carries its own licence. That code is usually not open source even where the rest is; what the buyer may do with each part differs.

Evidence
pro/EULA.md — licence: LicenseRef-EULA

Observability & Operations

adequate
06.2

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

Evidence
searched 123 files for 10 structured logging libraries; 0 matched
06.8

One request cannot be followed through the logs

adequate

Nothing in the service carries a request or correlation id, and there is no tracing. When a customer reports a failure, the log lines that belong to their request cannot be picked out from everyone else's.

Evidence
no request id, correlation id or tracing found
06.9

No error reporter is wired in

adequate

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.

Evidence
no error reporter initialised
