replication problem (1.0.1 error on ensure_full_commit)

["Kevin R. Coombes" <ke...@gmail.com>]

Hi,

I'm having (another) problem trying to replicate a Couch database.  
Replication begins just fine, but at random points I get the following 
log message:

[Mon, 20 Jun 2011 20:34:36 GMT] [error] [emulator] Error in process 
<0.630.0> with exit value: {{nocatch,{invalid_json,<<231 
bytes>>}},[{couch_util,json_decode,1},{couch_rep,ensure_full_commit,2},{couch_rep,'-commit_to_both/3-fun-0-',3}]}

At this point, replication halts and does not resume.  Both the source 
and target couchdb's are running version 1.0.1.  Replication was started 
by a POST to the target machine.

The source machine is behind a proxy which only allows HTTP GET 
commands.  (Well, it will allow PUT commands if you authenticate 
properly.)  I suspect that the problem is that the "ensure full commit" 
step tries to PUT a checkpoint document back to the source machine.

Is that correct?  If so, is there any way to replicate a database from a 
couch server that only allows GET commands?

Thanks for your help,
     Kevin

_ensure_full_commit is a POST.
If you initiate on the target it will be only GET requests, I believe.
I'm not sure which way you did it. Please follow up if you see
problems like this when pulling (by initiating the replication from
the target).
