Subject [jira] [Commented] (COUCHDB-1340) Replication: Invalid JSON reported
Date Wed, 16 Nov 2011 10:58:52 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13151137#comment-13151137
] 

Filipe Manana commented on COUCHDB-1340:
----------------------------------------

Alex, the only cases I've seen this happening are due to the pipeline or documents in the
source with an empty ID (or consisting only of white spaces). Or perhaps, there's some firewall
in the middle interfering.
Also, for a quick test, do you think you can try pull replicating with the 1.2.x branch? (it's
not an official release, only for testing) That branch has a new replicator.

thanks

> It was all working until we upgraded some other couches in our replication "web" from
couch 1.0.3 to couch 1.1.1. We then set of database and view compactions, and sometime overnight
some of the replication links stopped.
> I have curled the command myself, both as a multipart message and a single json response
(with header "Accept:application/json" ) and it can be parsed correctly by Python simplejson
- I have attached it here aswell - called "troublecurl-redacted.txt" - though it is 18.8mb.
The request takes about 6 seconds.
> I don't quite understand why it is reported as invalid JSON? Other reports similar to
this that I googled mentioned blank document ids, but I can't see any of these.
