Joan Touzet updated COUCHDB-345:
--------------------------------
Attachment: badtext.tar.gz
Code to reproduce the defect including the pre-requisite wrapper module.
> "High ASCII" can be inserted into db but not retrieved
> ------------------------------------------------------
>
> Key: COUCHDB-345
> URL: https://issues.apache.org/jira/browse/COUCHDB-345
> Project: CouchDB
> Issue Type: Bug
> Affects Versions: 0.9
> Environment: OSX 10.5.6
> Reporter: Joan Touzet
> Attachments: badtext.tar.gz
>
>
> It is possible to PUT/POST a document into CouchDB with a "high ASCII" value
> that cannot be retrieved. This results from not escaping a non-ASCII value
> into \u#### when PUT/POSTing the document.
> This sample code will recreate the problem using the hex value D8 (Ø) in a
> possibly unsavoury test string. It requires the file Couch.py in the same
> directory, containing the code from the "Example wrapper class" at
> http://wiki.apache.org/couchdb/Getting_started_with_Python to run.
> ================================================
> #!/usr/bin/python
> from Couch import Couch
> db = Couch('localhost', '5984')
> db.createDb('utf8_fail')
> badtext = "4E45494D454E2046D85252204641454E21".decode("hex")
> doc = """
> {
> "Message":\"""" + badtext + """\",
> }
> """
> db.saveDoc('utf8_fail', doc, 'fail')
> db.openDoc('utf8_fail', 'fail')
> ================================================
> Sample output against 0.9.0 is as follows:
> {
> "ok": true
> }
> {
> "id": "fail",
> "ok": true,
> "rev": "1-76726372"
> }
> {
> "error": "ucs",
> "reason": "{bad_utf8_character_code}"
> }
> ================================================
> Please note this defect turned up another problem, namely that the
> bad_utf8_character_code exception thrown by a design document attempting to
> map() the bad document caused Futon to fail silently in building the view,
> with no indication (except via debug log) that there was a failure. The log
> indicated two attempts to build the view, both failing, followed by an
> uncaught exception error for Futon.
> Based on this, there are likely other areas in the codebase that do not
> handle the bad_utf8_character_code exception correctly.
> My belief is that CouchDB shouldn't accept this input and should have
> rejected the PUT/POST, or should have escaped the input itself before the
> insertion.
