A tool for detecting bit rot in files.
A small utility for checking for bit rot. This project is heavily influenced by chkbit and bitrot. Both projects had things I liked about them and other things that I didn’t. I took what I liked and made something myself.
The focus of Rotten Bites is scalability and speed. To achieve this, small files (.bit_check) are placed in every directory. I know, no one wants a “bunch of turdy files sprinkled all over your hard drive”, but in my opinion it is the best way to allow for flexibility (folders can be moved around without any problem because all paths are relative to that directory) and scalability (having one central database with all files stored does not scale well).
There are two components to Rotten Bites: the CLI and library. I designed Rotten Bites to be callback based so it makes it easy to extend. See the CLI (rotten_bites/__main__.py) and rot_check.py, for examples.
pip install rotten_bites
Usage: rotten_bites [OPTIONS] DIRECTORY Given a directory, rotten bites calculates the sha1 hash of every file and stores it in .bit_check files. Once stored, subsequent checks will see if the hash has changed, detecting bit rot. Status codes: 'E' error, sha1 mismatch 'a' add to index 'u' update sha1 ' ' not modified (shown only with verbose) '?' could not read file (permission denied or file no longer exists) Options: --delete Delete all .bit_check files. -n, --dry-run Run without making any changes. No .bit_check files are created or updated --ignore-list FILENAME List of files and folders to ignore. Similar syntax to .gitignore files. "-" can be used to read from stdin. -q, --quiet Turn off all output except for hash errors. -v, --verbose Display all files that are scanned, even if they haven't changed --verify Verify hashes without updating. --help Show this message and exit.
