-------------------------------------

             Summary: literal '+' in database create URL should succeed
                 Key: COUCHDB-1580
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1580
             Project: CouchDB
          Issue Type: Bug
          Components: HTTP Interface
    Affects Versions: 1.2
         Environment: Linux Ubuntu 12.04
            Reporter: Sam Stainsby
            Priority: Minor


Plus ('+') only have special meaning in the query part of a URL, not the path 
part. So, the following should succeed:

curl -X PUT 'http://localhost:5984/aaa+bbb'

but instead it results in an error: "Only lowercase characters (a-z), digits 
(0-9), and 
any of the characters _, $, (, ), +, -, and / are allowed ...". Couchdb is 
requiring the '+' to be percent encoded, so this *does* succeed:

curl -X PUT 'http://localhost:5984/aaa%2bbbb'

This causes problems with the latest Dispatch library (version 0.9.3), which 
(quite correctly) leaves '+' characters intact when adding a path segment. If 
you pre-encode the '+', then you'll get double encoding instead, so there is no 
neat solution.

Refer to RFC 3986 Appendix A's BNF to see that '+' is a valid path segment 
character. See also:

"Within the query string, the plus sign is reserved as shorthand notation for a 
space. Therefore, real plus signs must be encoded. This method was used to make 
query URIs easier to pass in systems which did not allow spaces." 
(http://www.w3.org/Addressing/URL/4_URI_Recommentations.html)

"For HTTP URLs, a space in a path fragment part has to be encoded to "%20" 
(not, absolutely not "+"), while the "+" character in the path fragment part 
can be left unencoded."
