After upgrading to Rails 6.1.7.2 one of our apps printed a wall of warnings while booting:
/var/www/app/shared/bundle/ruby/2.6.0/gems/net-protocol-0.2.1/lib/net/protocol.rb:68: warning: already initialized constant Net::ProtocRetryError
/home/deploy-app/.rbenv/versions/2.6.10/lib/ruby/2.6.0/net/protocol.rb:66: warning: previous definition of ProtocRetryError was here
/var/www/app/shared/bundle/ruby/2.6.0/gems/net-protocol-0.2.1/lib/net/protocol.rb:214: warning: already initialized constant Net::BufferedIO::BUFSIZE
/home/deploy-app/.rbenv/versions/2.6.10/lib/ruby/2.6.0/net/protocol.rb:206: warning: previous definition of BUFSIZE was here
/var/www/app/shared/bundle/ruby/2.6.0/gems/net-protocol-0.2.1/lib/net/protocol.rb:541: warning: already initialized constant Net::NetPrivate::Socket
/home/deploy-app/.rbenv/versions/2.6.10/lib/ruby/2.6.0/net/protocol.rb:503: warning: previous definition of Socket was here
We could fix this by adding the following to our Gemfile
:
gem 'net-http', require: false
gem 'net-imap', require: false
gem 'net-protocol', require: false
gem 'net-smtp', require: false
Background
- https://github.com/ruby/net-imap/issues/16 Show archive.org snapshot
- https://github.com/shakacode/shakapacker/issues/206 Show archive.org snapshot
Alternative
Turned out that it was caused by an update of the mail
gem from 2.7.0
to 2.8.0.1
.
So another possibility would be to stay at version 2.7.0
.
