resolv-macos
On macOS/darwin, libresolv
supports multiple resolvers. This allows users, VPN
clients, etc. to delegate queries for certain domains to other resolvers, in
addition to the "Super Resolver" specified by /etc/resolv.conf
. An example of
this would be using something like dnsmasq
or launchdns
to resolve a
Special Use Domain (described by RFC 6761)
for local development like *.localhost
or *.test
This is supported transparently via the gethostbyname
and getaddrinfo
C
calls, but when replacing use of those APIs w/ Resolv
, these resolutions no
longer happen automatically.
This Gem patches the default behavior of the Resolv
gem to include these
additional resolvers in the default set, if they exist. (Using public APIs,
there's no monkey-patching here.)
Installation
Add this line to your application's Gemfile:
gem 'resolv-macos'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install resolv-macos
Usage
No special usage instructions. The Gem will patch Resolv
to automatically
provide support for multiple resolvers on macOS, a la the default behavior for
getaddrinfo
. On platforms other than macOS, this gem does nothing.
Development
After checking out the repo, run bin/setup
to install dependencies. Then, run
rake spec
to run the tests. You can also run bin/console
for an interactive
prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To
release a new version, update the version number in version.rb
, and then run
bundle exec rake release
, which will create a git tag for the version, push
git commits and tags, and push the .gem
file to rubygems.org.
