Some unit tests are broken on Ruby 3.0 #3263

kenhys · 2021-02-19T08:19:16Z

Check CONTRIBUTING guideline first and here is the list to help us investigate the problem.

Describe the bug

Drone CI is continuously broken for two months.
See https://cloud.drone.io/fluent/fluentd

To Reproduce

Follow steps in .drone.yml

See https://github.com/fluent/fluentd/blob/master/.drone.yml#L26-L35

Expected behavior

There are 3 test case failures.

kenhys · 2021-02-22T06:04:11Z

First test case:
It is strange that the following sample code execution result is the same on amd64 and arm64v8. 😕

@example = ConfigurableSpec::ExampleWithSkipAccessor.new
@example.configure(config_element('ROOT'))

p @example.inspect

Then ruby -Ilib test/config/test_configurable.rb

ruby 2.7.2 amd64 ng
ruby 3.0 amd64 ok
ruby 3.0 arm64 ok

kenhys · 2021-02-22T06:31:04Z

Failure: test: when out_forward has @id(ForwardOutputTest): test case will be fixed by specifying parent explicitly.

kenhys · 2021-02-22T06:37:08Z

Revised #3262 for fixing 2nd test case.

ashie · 2021-03-05T09:06:56Z

There are 3 test case failures.

They aren't Drone or Arm specific, it's caused by combination of Ruby 3.0 and RR.
As I described in #3262 (comment) RR's Proxy doesn't seem support Ruby3.0's kwargs, we need to fix RR.
As a first aid I omitted these test on Ruby 3.0.

#3263 (comment) It is not clarified the problem well. it may differ between Ruby 2.7 (raise EADDRINUSE) and Ruby 3.0 (NO error)

#<Socket::Option: INET SOCKET REUSEADDR 0> is not set both of them (2.7/3.0)

kenhys · 2021-03-17T01:31:48Z

I'll try a reproducible minimum script.

kenhys · 2021-03-17T09:15:15Z

It seems SocketManager.send_peer succeeds (TCPSocket writes packed data - 91 bytes), but SocketManager.recv_peer behaves differently.

https://github.com/treasure-data/serverengine/blob/6e4dc985f83829811532934f136d5f2204740daa/lib/serverengine/socket_manager.rb#L51-L53

kenhys · 2021-03-18T07:27:40Z

Both of 2.7/3.0, WinSock.bind(sock.handle, sock_addr, sock_addr.bytesize) returns -1, but RbWinSock.raise_last_error("bind(2)") raise Errno::NOERROR in 3.0.

https://github.com/treasure-data/serverengine/blob/6e4dc985f83829811532934f136d5f2204740daa/lib/serverengine/socket_manager_win.rb#L85-L87

kenhys · 2021-03-19T05:53:02Z

I've found bind return -1, but WinSock.WSAGetLastError returns 0.

https://github.com/treasure-data/serverengine/blob/6e4dc985f83829811532934f136d5f2204740daa/lib/serverengine/winsock.rb#L101-L104

kenhys · 2021-03-22T04:11:44Z

I've found bind return -1, but WinSock.WSAGetLastError returns 0.

Thread.current is same (bind(2) and WinSock.WSAGetLastError()) then mutex.synchronize do block doesn't resolve the issue.

kenhys · 2021-03-23T02:19:39Z

I got feedback to reproduce it

  extern 'int bind(int, void *, int)'
  extern 'int WSAGetLastError(void)'

Failed tests are passed, but it seems crash on certain tests.
It reproduces on both my local environment & GitHub Actions.

And bundler doesn't accept fiddle 1.0.8 on Windows: https://github.com/rubygems/bundler/blob/35be6d9a603084f719fec4f4028c18860def07f6/spec/runtime/setup_spec.rb#L1211

On Ruby 3.0, we need to use fiddle 1.0.8 or later to retrieve correct error code. In addition, we have to specify the path of fiddle by RUBYLIB because RubyInstaller loads Ruby's bundled fiddle before initializing gem.
