Misleading error "Referer header required." when POSTing without a body
-----------------------------------------------------------------------
Key: COUCHDB-1025
URL: https://issues.apache.org/jira/browse/COUCHDB-1025
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Affects Versions: 1.0.1
Environment: Ubuntu 10.10, Perl modules involved: LWP 5.836, JSON::Any
1.22, JSON 2.21, JSON::XS 2.29
Reporter: Malte S. Stretz
Priority: Minor
This one gave me headaches. I use the simple Perl library from
<http://wiki.apache.org/couchdb/Getting_started_with_Perl> in combination with
JSON::Any to push ~63000 documents to a database. Since I later want to sync
this data with outside changes, I calculated a hash of each document and
generated a document /hashes which maps the hashes to document names (I know,
not the best solution, but this should have been only a quick hack and I wanted
to keep the hashes out of the actual documents). After I split the bulk
pushing into batches of 1024 to get around timeouts in LWP, uploading the data
itself works fine. But the /hashes document always fails with
{"error":"bad_request","reason":"Referer header required."}.
After a lot of prodding in the wrong corners, Wireshark came to the rescue. The
data sent and received is quoted below; there appears to be some
problem/bug/config issue in LWP with POSTing large documents: The
Content-Length is set but no body is sent. This is not good. But the error
message coming back from CouchDB is almost worse :)
