Nolan Lawson created COUCHDB-2978:
-------------------------------------
Summary: ETag should not be sent for _local docs
Key: COUCHDB-2978
URL: https://issues.apache.org/jira/browse/COUCHDB-2978
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Reporter: Nolan Lawson
CouchDB re-uses the same ETags for _local documents even when the content of
the _local document has changed, meaning that clients who cache based on the
ETag may end up with permanently stale content. To reproduce the bug, it's
simply:
1. Create a _local doc
2. Fetch the doc, ETag is "0-1"
3. Delete the database (or the _local doc)
4. Recreate the database (or the _local doc), insert a *changed* _local doc
5. Fetch the doc, ETag is still "0-1" and therefore the client may end up with
a stale version.
