---------------------------------------
Summary: Error reading document after multipart put
Key: COUCHDB-1525
URL: https://issues.apache.org/jira/browse/COUCHDB-1525
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Affects Versions: 1.2
Environment: Mac OS 10.6.8
Reporter: Julian Goacher
Priority: Blocker
Fix For: 1.3
GETing a document after a multipart PUT which uploaded an attachment generates
a 500 error. To reproduce:
Following document is in a DB (called semo_test here).
{
"_id": "doc0",
"_rev": "1-7e97409c987eac3a99385a17ad4cbabe",
"value": 0
}
Update the document and add an attachment using a multipart/related request:
PUT /semo_test/doc0 HTTP/1.1
Accept: application/json, */*
content-type:
multipart/related;boundary=multipart_related_boundary~~~~~~~~~~~~~~~~~~~~
Host: localhost:5984
Content-Length: 435
Connection: keep-alive
--multipart_related_boundary~~~~~~~~~~~~~~~~~~~~
Content-Type: application/json
{"value":0,"_id":"doc0","_rev":"1-7e97409c987eac3a99385a17ad4cbabe","_attachments":{"plus
1":{"stub":false,"follows":true,"content_type":"application/json","length":14}},".cache":{"plus
1":{"timestamp":"2012-08-13T13:59:27.826Z"}}}
--multipart_related_boundary~~~~~~~~~~~~~~~~~~~~

(This problem was originally reported on user@couchdb and Robert Newson
requested that I raise it here. Note that these steps generate the error as
described when I test on one couchdb installation, but when I try the same
steps on a separate installation - also Mac OS 10 - the 500 error doesn't
occur, so possibly the error is somehow related to db state).
