Subject [jira] [Closed] (COUCHDB-1310) '/_restart' closes request socket before sending a response
Date Sat, 26 Jan 2013 20:57:12 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-1310?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Randall Leeds closed COUCHDB-1310.
----------------------------------

    Resolution: Won't Fix

Impossible to send a response after the server has restarted... the socket has been closed
as part of the restart.

> In 'couchdb_misc_handlers.erl', `handle_restart_req(...)` calls `couch_server_sup:restart_core_server()`
before sending the HTTP response.  This causes the current request's socket to be closed without
sending any response back to the client.  From the perspective of the HTTP client, the connection
is simply dropped - no response is ever received.  
> In addition to the obvious aesthetic problems here, the HTTP1.1 spec suggests a specific
(and non-desirable) client-side behavior for connections that drop like this. From RFC-2616
Section-8.2.4: "...if the client sees the connection close before receiving any status from
the server, the client SHOULD retry the request..." (http://tools.ietf.org/html/rfc2616#section-8.2.4).
 Any HTTP client that actually obeys this direction, would end up restarting the server multiple
times.
> I have a patch that fixes this issue. I will attach it to this report.
