geth-rebuild

A rebuilder for geth.

Reproduce and verify source-to-binary semantics of a geth binary artifact.

Usage

go build ./cmd/gethrebuild

./gethrebuild <os> <arch> <version>

For example, gethrebuild linux-amd64 1.14.3

See command documentation for optional arguments gethrebuild --help

Note

Must be run inside project directory 🩸

Cases of Unreproducibility

When reproducing an artifact, cases of non-determinism need to be controlled.

In .non-determinism/reports four cases found for geth are shown:

• buildid: embedding of unreproducible build ids
• date: conditional embedding of release date
• path: embedding of absolute system paths
• gcc: differing gcc versions using identical build settings

Reproduce these cases by running #TODO
