NoMethodError empty? false:FalseClass

[ethanghunt]

We have been working on API integrations and have often been running into this error when the targeted API is taking too much traffic.

undefined method `empty?' for false:FalseClass
.../ruby/gems/openssl-3.3.0/lib/openssl/buffering.rb:216:in `read_nonblock'

openssl/lib/openssl/buffering.rb

Line 216 in e5153db

if @rbuffer.empty?

@rbuffer is false in this scenario, and unfortunately, boolean does not respond to .empty?

I noticed that this line of code has moved or been removed in the most recent commit of the repo, so some investigation may need to be done or it may already be fixed.

Thank you!

@rbuffer is only used in lib/openssl/buffering.rb, and is assigned only once in #initialize. So I don't see how it can become false.

Can you provide a reproducer?

I will do my best. It is an odd, probabilistic problem. Might take some time. I will let you know if I can't find the time.
In the meantime, we fixed this by adding empty? to FalseClass.
