reproducible

Create reproducible archives

Usage

./reproducible.py -d dir_to_archive -o archive.tar.gz  \
                  --prepend RepoName-master --timestamp 1414213562

Tips

First, get a .tar.gz file

• GitHub users: download the archive using the green button or from the Release section.

• Git users: git archive --format=tar.gz --prefix=topfolder/ -o out.tar.gz master or v1.2.3

• PyPI users: python3 setup.py sdist

Extract the archive, stripping the top folder

mkdir out_dir
tar -xf out.tar.gz -C out_dir --strip 1

Pack the archive, deterministically

./reproducible.py -d out_dir -o archive.tar.gz --prepend RepoName-master

Note

Check your timestamps! Python uses the zipfile module to build wheels, and it has trouble dealing with pre-1980 timestamps.
