Invalid character in request causes double HTTP response -- 200 and 500
-----------------------------------------------------------------------
Key: COUCHDB-48
URL: https://issues.apache.org/jira/browse/COUCHDB-48
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Environment: Debian (/etc/debian_version says lenny/sid, can never
keep their versioning straight). Running CouchDB built from today's source.
Accessing via ClouchDB.
Reporter: Eli Naeher
I inadvertently created a document with an ID which contains the sequence
"%da", which when URL-decoded is apparently not a valid UTF-8 character.
Instead of receiving the appropriate error, I got an HTTP 200 followed by an
HTTP 500, both in response to the same request.
Additionally, the document seems to have been created, since accessing certain
pages of the list of documents in the built-in web interface causes the same
500 error to show up in the CouchDB logs.
Here is a Wireshark capture which explains the issue:
