Subject [jira] Created: (COUCHDB-883) Wrong document returned due to incorrect URL decoding
Date Wed, 08 Sep 2010 14:05:32 GMT
Wrong document returned due to incorrect URL decoding
-----------------------------------------------------

                 Key: COUCHDB-883
                 URL: https://issues.apache.org/jira/browse/COUCHDB-883
             Project: CouchDB
          Issue Type: Bug
          Components: HTTP Interface
    Affects Versions: 1.0.1
         Environment: Kubuntu 10.4, Firefox 3.6.8
            Reporter: Taras Puchko


I have two documents in my database: "a b" and "a+b". The first can be retrieved via "/mydb/a%20b"
and the second via "/mydb/a%2Bb".

When I enter "/mydb/a b" in the browser it automatically encodes it so the correct document
is returned. But when I enter "/mydb/a+b" the URL is sent intact since "+" is a valid character
in a path segment according to [1]. The problem is that "GET /mydb/a+b" makes CouchDB return
the document with id "a b" and not the intended one, which is against the URI spec .

For an informal description of URL encoding one may refer to [2].
