Subject [jira] Commented: (COUCHDB-345) "High ASCII" can be inserted into db but not retrieved
Date Sat, 29 Aug 2009 09:53:32 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12749103#action_12749103

Jan Lehnardt commented on COUCHDB-345:
--------------------------------------

I'd be happy to see in code what Noah suggests down the road. But until we get such a patch
we should go with denying non-utf-8 encoding if we can't handle it correctly. I don't think
this is lazy as a first approach

>             Project: CouchDB
>          Issue Type: Bug
>    Affects Versions: 0.9
>         Environment: OSX 10.5.6
>            Reporter: Joan Touzet

> 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.
> The attached sample code will recreate the problem using the hex value D8 (Ø) in a possibly
unsavoury test string.
> 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.
