Python dont need a raw Binary unless you are distributing *.PYC without *.PY.
These tools were created for Building Binaries in a reproducible Build , here use use them to make reproducible Test.
Whatsoever creating more randomized environment for isolated unittests is always good and helps spot Bugs.
The rest of the tools for Reproducible Builds are more oriented to compiled language builds.
Disorderfs is an overlay FUSE filesystem that introduces non-determinism into filesystem metadata. For example, it can randomize the order in which files and directories are read. This is useful for detecting non-determinism in the build/testing process. This checks that your software is filesystem-ordering agnostic.
- Debian/Ubuntu:
sudo apt-get install disorderfs - Arch:
pacman -S disorderfs - Git: https://github.com/ReproducibleBuilds/disorderfs
Run on foreground, to see Debug, CTRL+C to stop and unmount:
disorderfs -d --shuffle-dirents=yes -o auto_unmount SOURCE_DIR DESTINATION_MOUNT_DIR
Run on background, for Travis CI, cant CTRL+C, cant stop or unmount:
disorderfs --shuffle-dirents=yes SOURCE_DIR DESTINATION_MOUNT_DIR
Stop and unmount on background, for Travis CI:
sudo umount --verbose /tmp/temp
At the time of wrting this, Travis CI dont support Disorderfs, because its Ubuntu is too old. Can be run locally without problem.
