lib/mail/utilities.rb:160: warning: URI::RFC3986_PARSER.escape is obsolete. Use URI::RFC2396_PARSER.escape explicitly

[rgaufman]

I'm getting this warning for every email I send:

/lib/ruby/gems/3.3.0/gems/mail-2.8.1/lib/mail/utilities.rb:160: warning: URI::RFC3986_PARSER.escape is obsolete. Use URI::RFC2396_PARSER.escape explicitly

Please replace URI::DEFAULT_PARSER and RFC3986_PARSER with RFC2396_PARSER.

Hello @rgaufman. I've just attempted to reproduce this in a brand new Rails 8.0.1 app, on Ruby 3.4.1, but I was unable to:

mail1629(dev)> NotifierMailer.welcome_email("test@ryanbigg.com")
  Rendering layout layouts/mailer.html.erb
  Rendering notifier_mailer/welcome_email.html.erb within layouts/mailer
  Rendered notifier_mailer/welcome_email.html.erb within layouts/mailer (Duration: 0.5ms | GC: 0.0ms)
  Rendered layout layouts/mailer.html.erb (Duration: 1.3ms | GC: 0.0ms)
NotifierMailer#welcome_email: processed outbound mail in 87.9ms
=> #<Mail::Message:7616, Multipart: false, Headers: <From: from@example.com>, <To: test@ryanbigg.com>, <Subject: Welcome to My Awesome Site>,

Out of curiosity, what version of the uri gem does your application use?

I believe this addresses it: #1620
