nickva opened a new pull request #1452: Switch fabric attachment reciever to use messages instead of function closures
URL: https://github.com/apache/couchdb/pull/1452
 
 
   
   Function closures are fragile and attachment uploads would break if
   fabric_doc_attachments is different on any of the nodes in a cluster, like it
   might happen during a roling cluster upgrade.
   
   Previously fe53e437ca5ec9d23aa1b55d7934daced157a9e3 introduced two versions of
   the module one which handles function closure, other which handled message but
   only in this commit messages are starting to be sent.
   
   To avoid breakages in attachemnt uploads during the period of a rolling cluster
   upgrade, make sure to upgrade to that commit first then upgrade to this change.
   
   Issue #1394
