Feature #14035: URI module always serializes to the minimal form insted of the traditional one

Reproduce

execute URI("file:///etc/hosts").to_s

I expect

• URI("file:///etc/hosts").to_s == "file:///etc/hosts"

• URI to preserve traditional form instead converting it to the minimal one (Eg. see https://tools.ietf.org/html/rfc8089#appendix-B )

I wish

• URI to preserve the minimal/traditional form.

URI("file:///etc/hosts").to_s == "file:///etc/hosts"
URI("file:/etc/hosts").to_s == "file:/etc/hosts"

Instead

• URI("file:///etc/hosts").to_s == "file:/etc/hosts"

• URI("file:///etc/hosts").host == nil

Proposal for Ruby 2.4

Adopting the convention of an "empty host" instead of no authority when the passed string has the traditional form.

• file schema to have a blank/empty "" host

suggested in rfc3986 will fix the issue.

   If the URI scheme defines a default for host, then that default
   applies when the host subcomponent is undefined or when the
   registered name is empty (zero length).  For example, the "file" URI
   scheme is defined so that no authority, an empty host, and
   "localhost" all mean the end-user's machine, whereas the "http"
   scheme considers a missing authority or empty host invalid.

[phluid61 (Matthew Kerwin)]

The spec for file URIs is RFC8089, which allows for file URIs with no authority part (e.g. 'file:/foo').

Neither it nor RFC3986 make any claims about canonical representation of URIs, much as I may have liked it to.

Also, have a look at the 'file-uri' gem.

Ok.

I read here https://tools.ietf.org/html/rfc8089#appendix-B reports that there is a traditional form though.
Clearly traditional != canonical ;)

Checked gem, thx++

Introduce URI::File to handle file URI scheme

• the default value of URI::File's authority is "" (localhost).
  Both nil and "localhost" is normalized to "" by default.
• URI::File ignores setting userinfo and port
