[ruby-core:87762] [Ruby trunk Bug#14891] Pathname#join has different behaviour to File.join

From: shevegen@...
Date: 2018-07-03 07:24:23 UTC
List: ruby-core #87762
Issue #14891 has been updated by shevegen (Robert A. Heiler).


This behaviour surprised me too. Is it expected that the information from "/a"
is lost? I have no idea but the documentation does not mention this; perhaps
the above could be added as an example OR the behaviour changed (or both).

I have little to none experience with pathname these days as I seem to handle
paths ... without pathname. :D

Documentation to Pathname .join is at:

Bug #14891: Pathname#join has different behaviour to File.join

~~~ ruby
Pathname.new('/a').join('/b').to_s
# => "/b"
File.join(Pathname.new('/a'), '/b').to_s
# => "/a/b"
~~~

in my case `'/b'` was in a variable and it wasn't immediately obvious why it wasn't working when I moved to use Pathname

This seems to not be desired behaviour as it's different to `File.join`, and this case isn't document anywhere.

Can we either change the behaviour to treat the "other" of `Pathname#+` as always relative (possibly just removing a leading slash), or add this case to the documentation?
