sftp raises Net::SFTP::StatusException when globbing is not possible ( Alpine linux )

[onnimonni]

Hey!

I just created a sftp server docker image with alpine for my integration tests:
https://github.com/CheckoutFinland/docker-dummy-sftp-server

I then tried to use glob file matching like this:

def fetch_sftp
  Net::SFTP.start(uri.host, uri.user, port: uri.port, key_data: [private_key], keys: [], keys_only: true) do |sftp|
      sftp.dir.glob(uri.path, '*.csv') do |remote_file|
           puts remote_file
      end
  end
end

Which raises weird looking:

Traceback (most recent call last):
        2: from (irb):5
        1: from test.rb:45:in `block in fetch_sftp'
Net::SFTP::StatusException (Net::SFTP::StatusException)

I found out that this probably happens because alpine linux uses musl-c library which doesn't support glob.

I'm not sure if we can deduce if glob is supported from the sftp connection or not but this error message could be better. At least I posted this issue here so that others can find it with google.
