Bug #16462
closedRuby 2.7 autoload not working with $RUBYLIB (maybe circular dependency error)
Description
I don't know how to exactly describe this issue, following is try to reproduce.
We can use a gem named "looksee", it was supported ruby 2.7 ready.
same issue happen on several gem, looksee is just for a sample for describe this issue.
- i change $RUBYLIB ENV locally for use some gem easy. (globally used by all my own local project)
╭─ 17:41 zw963 ⮀ ~ ⮀ ➦ ruby-2.7.0
╰─ $ echo $RUBYLIB
/home/zw963/Dropbox/common/ruby/lib
- Following is my directory content for my ~/Dropbox/common/ruby/lib, code is working.
╰─ $ tree

- the reason cause this is, i guess, following code is not working, some circular dependency was happen.
module Looksee
...
autoload :Adapter, 'looksee/adapter'
...
end
Please check the source code here:
https://github.com/oggy/looksee/blob/master/lib/looksee/clean.rb#L12
- if
require "looksee/adapter"
directly, it working.
╰─ $ RUBYOPT= irb -f
irb(main):001:0> require 'looksee/adapter'
=> true
But, if require "looksee"
first, then require "looksee/adapter"
, still broken.
╰─ $ RUBYOPT= irb -f
irb(main):001:0> require 'looksee'
