According to upstream, there's a bug in CouchDB 1.0.0 that could potentially result in a loss of data. Just thought I'd report this.
Thanks for highlighting this critical version bump! Assigning to couchdb maintainer.
Well, 1.0.1 is not released yet, so it's not a version bump yet. Not sure if we should pmask 1.0 for now.
If it's at all relevant, there's also a repair tool to help recover data that could've potentially been lost because of this bug: http://wiki.couchone.com/page/repair-tool/
1.0.1 is committing as we speak.
