CouchDB upgrade on CentOS


We were trying to upgrade CouchDB to the latest version (v1.1.1) on the CentOS operating system. Unfortunately, had to put this task on hold as the CouchDB EPEL repository (used by yum package manager) does not have this latest version available.

Here is the link for the repository: http://download.fedora.redhat.com/pub/epel/6/SRPMS/repoview/couchdb.html
The CouchDB version available in the repository is 1.0.2.

Any idea when is the repo going to get updated with the latest version of CouchDB?
Has anybody else faced this issue? Is there any alternate solution to this?

CouchDB: Unrecognized field “digest” when fetching documents with attachments


Today, while trying to fetch a document (having a .wav file as an attachment) from CouchDB, came across this exception:

org.ektorp.DbAccessException: org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field “digest” (Class org.ektorp.Attachment), not marked as ignorable

After doing a bit of research, figured out that this happened because the version (v1.1.1) of ektorp that I am using  seems to be incompatible with v1.1.0 of CouchDB. This version of CouchDB expects a new “digest” attribute containing the MD5 checksum (for the attachment) in the document that contains the attachment. However, ektorp v1.1.1 does not find a corresponding Java property while deserializing, which results into this exception. Looks like this change was introduced in CouchDB v1.1.0 to address this issue – https://issues.apache.org/jira/browse/COUCHDB-687.

For now, downgrading CouchDB to v1.0.2 resolved this issue for me.
