Bug #8352: uri squeezes a sequence of slashes in merging paths when it shouldn't
https://bugs.ruby-lang.org/issues/8352#change-39077

Author: knu (Akinori MUSHA)
Status: Open
Priority: Normal
Assignee: akira (akira yamada)
Category: lib
Target version: 
ruby -v: ruby 2.1.0dev (2013-05-01 trunk 40540) [x86_64-freebsd9]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


RFC 2896 (on which the library currently is based) or RFC 3986 says nothing about a sequence of slashes in the path part except for parsing rules when a URI (path) starts with two slashes.

It should be perfectly valid to have a slash right after another, and there is no reason to "normalize" a sequence of slashes into a single slash, which uri actually does in merging paths:

URI.parse('http://example.com/foo//bar/')+'.'
=> #<URI::HTTP:0x0000080303d2b0 URL:http://example.com/foo/bar/>

Fixing this may be as easy as changing the regexp in URI::Generic#split_path from %r{/+} to %r{/}, but I wonder how the impact of incompatibility it may introduce would be.
