hosts-resolver (1.1.0)
Installation
pip install --index-url About this package

hosts_resolver
Zero-dependency Python module to resolve names using /etc/hosts alone
Rationale
Sometimes we only want to resolve names using /etc/hosts entries without performing DNS requests (thus socket.getaddrinfo is out of the equation).
So there are three options :
- manually parse /etc/hosts
- call
getentprogram and parse its output - use this module (which binds libc
gethostentfunction) !
Limitations
gethostentis not reentrant (see GETHOSTBYNAME(3))gethostentis not thread-safe (see GETHOSTBYNAME(3))- glibc implementations does not support IPv6 addresses (see GETHOSTBYNAME(3))
- behavior is undefined when using multiple context managers simultaneously
Installation
pip3 install --index-url https://git.forestier.app/api/packages/HorlogeSkynet/pypi/simple/ hosts-resolver
# or manually download latest Wheel and then :
pip3 install ./hosts_resolver-*-py3-none-any.whl
Usage
From API
from hosts_resolver.hosts_resolver import get_hosts_resolver
with get_hosts_resolver() as hosts_resolver:
print(hosts_resolver.resolve("localhost"))
# -> IPv4Address('127.0.0.1')
From CLI
Why bother ?? You should be looking at
getent!
hosts_resolver -j localhost
# -> {"localhost": "127.0.0.1"}
