Celluloid is a framework for building asynchronous and multithreaded Ruby programs using object-oriented concepts.

Revival Process Underway

Celluloid is in the process of being refactored and released back into the wild during Google Summer of Code. The next era will not have one individual active maintainer, but a team of collaborators. Going forward, previously dormant maintainer Donovan Keme is returning to support future primary maintainer Emese Padányi during GSoC 2020. Her plan extends past the Summer program, and aims to revive the community and codebase of Celluloid together. Backing this process are Harsh Deep and GSoC alumni Dilum Navanjana. We welcome your collaboration and contributions in this massive work.

The codebase is being refactored to pursue a stable release with no deprecation warnings, and with this cleaned up:

celluloid-dns's Issues

Server doesn't crash if actor crashes

Given this code:

RubyDNS::run_server(:listen => INTERFACES) do
  otherwise do |transaction|
    transaction.respond!("1.2.3.4")
  end
end

and this query:

nslookup -type=cname www.example.com

This error happens:

The actors are permanently crashed, but the error isn't raised up to the main ruby process, so that process continues on, but is unable to process additional requests.

Is there a way to have crashed actors result in an exception raised to the outer process?

I'm using rubydns, but I figure this is a celluloid-dns problem. Let me know if that's not the case.

README example does not work

on my machine (OS X 10.8) the server just hangs when a request is received, I think it just get stuck on "@block.call" which never calls the block but never returns either (just tested with a quick puts debugging ;) ).

is it supposed to work ?

I tested it with latest celluloid release (0.14.1) and I tested both latest celluloid-dns release and master with the same result :(

My workaround was to put this code:

  transaction.fail!( :NXDomain )
  return

DNS should use search domains by default?

Following from celluloid/celluloid-io#146 (comment)

• If an instance of Celluloid::DNS::Resolver is created, do we consult resolve.conf for every request?
• If a user specifies a search prefix, do we consult resolve.conf at all?
• How does resolv.conf work on Mac OS X and is it compatible with Linux? What about Windows?
• Does it make sense to use a native implementation of DNS for system-level DNS resolution, i.e. should we simply have Celluloid::DNS::Resolver defer to the OS supplied implementation?

Support EDNS

Hi,

Could you please support EDNS (https://tools.ietf.org/html/rfc6891)?

Thanks a lot.

Copy RubyDNS into Celluloid::DNS.

@tarcieri I am happy to put some time aside to do this. What do you think?

There are a couple of options:

Rename RubyDNS to Celluloid::DNS and add compatibility layer for existing code depending on Celluloid::DNS.

Copy specific parts (e.g. just resolver and/or just basic server, etc).

Something else?

/cc @digitalextremist @e2

Please update gem at rubygems.org

The latest version available at rubygems.org is 0.0.1. Because rubygems.org is the default gem source gem install celluloid-dns installs a non working gem for almost everybody:

$ gem install celluloid-dns
Successfully installed celluloid-dns-0.0.1
Parsing documentation for celluloid-dns-0.0.1
Installing ri documentation for celluloid-dns-0.0.1
Done installing documentation for celluloid-dns after 0 seconds
1 gem installed

Running specs on Mac OS X..

While the specs previously did pass on Mac OS X, after updating to celluloid 0.17.1 and celluloid-io 0.17.0 I've noticed some issues. It appears to still be fine on Linux. This is a meta-issue to figure out what exactly is the problem and how to resolve it.

Trouble running specs ?

Hi,

I'm really keen to use this gem it looks amazing and the possibilities for our team are great! I'm having trouble getting the example in the README to work and also when running the specs fail after around 15 seconds of idle ?

I get the same error with the following Ruby versions:

2.0.0-p0
2.0.0-p195
1.9.3-p194
