Deprecation notice regarding CompositeIO

[hackdna]

Ubuntu 20.04 LTS

Install librarian-puppet using Ruby that comes with Puppet 7 (ruby 2.7.6p219 (2022-04-12 revision c9c2245c0a) [x86_64-linux]):

/opt/puppetlabs/puppet/bin/gem install librarian-puppet -v 3.0.1 --no-document

Run /opt/puppetlabs/puppet/bin/librarian-puppet

The following message is added at the top of any output:

Top level ::CompositeIO is deprecated, require 'multipart/post' and use `Multipart::Post::CompositeReadIO` instead!
Top level ::Parts is deprecated, require 'multipart/post' and use `Multipart::Post::Parts` instead!

The following message is added at the top of any output:

A full stack trace is generally speaking more useful. Now it's really guess work. Luckily, I saw it somewhere else which gives me a general idea.

I think this comes from the faraday gem, which is pulled in via puppet_forge gem. There is a PR to add support for Faraday 2 which probably solves the deprecation warning. It'd be best to focus the efforts there.

Thank you for looking into this. The deprecation message is the only additional output I've received. How can I obtain a full stack trace?

Odd because in voxpupuli/modulesync_config#784 I saw it also report the file location.

Here's a full sample output:

Also, installation is broken with Puppet 6:
