What's New in CouchDB 1.0 Security 'n Stuff

Today, I get a little help from Rebecca. She's writing a CouchApp, an application that is served right out of CouchDB and that lives in the browser. It has no middle tier application server in Ruby or Java. The application and display logic is written in JavaScript, the user interface is HTML & CSS, the backend is CouchDB and uses Ajax to shove JSON back and forth.

WARNING: CouchDB 1.0.0 Data Loss bug

Update August 13, 2010. A data recovery tool now available: http://wiki.couchone.com/page/repair-tool

if you are running CouchDB 1.0.0 with the default delayed commit setting, you are subject to serious data loss on restart. See this page for instructions how to force all outstanding commits and configure your server at runtime to run in the safer full commit mode: http://couchdb.apache.org/notice/1.0.1.html

The page also includes details of the bug and a postmortem.

0.11.1 and earlier are unaffected. Servers with delayed commits turned off are unaffected. 1.0.1 will be coming shortly that fixes the problem in all configurations.

DO NOT COMPACT THE DATABASE! Compaction throws away any lost updates permanently.

Data recovery is coming. The CouchDB core contributors are working on a utility to reliably recover lost updates, so no data is lost as long the database file is not compacted.
