Greg Wilkins commented on SOLR-8453:
------------------------------------
If solr is in the habit of not consuming the content AND is particular about
how such connections are closed/reused, then I believe a filter should be
applied to all requests.
I will have a look again to see if jetty can provide consumeAll behaviour as an
option, but I really think that is just making solr dependent on a container
features... as it was when it assumed the container would consume all of the
input on it's behalf - which is behaviour not covered by any spec I know of.
Other than that, you could make a feature request on the client to be able to
handle request sending errors separately to response processing. Ie in this
case may receive a valid response and the request body send still failed.
> Jetty update from 9.2 to 9.3 causes the server to reset formerly legitimate
> client connections.

> The basic problem is that when we are streaming in updates via a client, an
> update can fail in a way that further updates in the request will not be
> processed, but not in a way that causes the client to stop and finish up the
> request before the server does something else with that connection.
> This seems to mean that even after the server stops processing the request,
> the concurrent update client is still in the process of sending the request.
> It seems previously, Jetty would not go after the connection very quickly
> after the server processing thread was stopped via exception, and the client
> (usually?) had time to clean up properly. But after the Jetty upgrade from
> 9.2 to 9.3, Jetty closes the connection on the server sooner than previous
> versions (?), and the client does not end up getting notified of the original
> exception at all and instead hits a connection reset exception. The result
> was random fails due to connection reset throughout our tests and one
> particular test failing consistently. Even before this update, it does not
> seem like we are acting in a safe or 'behaved' manner, but our version of
> Jetty was relaxed enough (or a bug was fixed?) for our tests to work out.
