tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
Readme
This package contains a trie of prefixes for fast lookups
trie = IPv4CIDRTrie()
cidrs = [ip_network(x) for x in ["1.2.0.0/16", "1.2.3.0/24", "1.2.3.4"]]
for cidr in cidrs:
# for mypy
assert isinstance(cidr, IPv4Network)
trie.insert(cidr)
for cidr in cidrs:
assert isinstance(cidr, IPv4Network)
assert cidr in trie
node = trie.get_most_specific_trie_supernet(cidr)
assert node is not None and node.prefix == cidr
invalid_cidrs = [ip_network(x) for x in ["1.0.0.0/8", "255.255.255.255"]]
for invalid_cidr in invalid_cidrs:
# for mypy
assert isinstance(invalid_cidr, IPv4Network)
assert invalid_cidr not in trie
assert trie.get_most_specific_trie_supernet(invalid_cidr) is None
assert IPv4Network("1.2.4.0/24") in trie
