Subject [jira] Commented: (COUCHDB-167) Files can not be attached to documents with forward slashes in their names to simulate a folder hierarchy
Date Tue, 02 Dec 2008 12:38:44 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12652350#action_12652350
] 

Tom Robinson commented on COUCHDB-167:
--------------------------------------

When I used Futon to add the attachment it used a colon instead of a forward slash, so I could
access the image at http://localhost:5984/test/_design%2Fnested/images%3Apickle.gif (%3A is
a colon)

You can use "%2F" in place of a forward slash, in which case it shows up as a forward slash
in Futon, but actually requires "%2F" in the URL.

If you *actually* try to save an attachment with a forward slash in it the request actually
crashes. For example, this:

    curl -v -H "Content-Type: image/gif" -T ~/pickle.gif http://localhost:5984/test/_design%2Fnested/images/pickle.gif?rev=3329617083

causes this error:

>                 Key: COUCHDB-167
>                 URL: https://issues.apache.org/jira/browse/COUCHDB-167
>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 0.9
>         Environment: Mac OS X 10.5.5, MacBook Pro, CouchDB 0.9.0a721757-incubating 
>            Reporter: Justin Walgran
>
> Steps to reproduce:
> 1) Download sample files from http://walgran.com/justin/CouchDB-nested-attachment-sample.zip
> 2) Unzip CouchDB-nested-attachment-sample.zip
> 3) Create a new CouchDB database
> 4) Create a new document called "_design/nested"
> 5) Add "index.html," "pickle.gif" and "images/pickle.gif" as attachments to the document
> 6) Browse the  index.html attachment
> Expected Behavior:
> Browsing index.html shows two copies of pickle.gif on the page
> Error:
> The second image fails to load. 
> Notes:
> Damien suggested using directory separators within file names to simulate folder hierarchies
in a November 28th response to the  couchdb-user@incubator.apache.org mailing list.
