Chris M. Hostetter commented on SOLR-16129:
-------------------------------------------
I should mention: Even if the bug causing SOLR-16129 is magically fixed in
jetty tomorrow, I still think this patch is useful for us because:
* it "future proofs" the solr client code from getting hung up on other bugs
like this that may exist
* it improves the solr client code to not wait around forever for a remote
server stalls out (and how long it's willing to waits is driven by
{{timeAllowed }}of the request)
> Solr specific InputStreamResponseListener to prevent client threads from
> hanging forever

> This issue tracks the implementation of workaround I suggested for SOLR-16099
> - it does not _fix_ the underlying bug (which as of this writting doesn't
> have an identified root cause) but it does ensure that client threads which
> encounter the bug won't hang forever...
> {quote}One thing we may want to consider (in Solr) is replacing our usage of
> {{InputStreamResponseListener}} with a variant implementation that uses a
> "timeout" instead of an unlimited {{wait()}} (along the lines of a [spin-off
> jetty enhancement issue|https://github.com/eclipse/jetty.project/issues/7259]
> one of the jetty devs filed). We could probably (with some effort) tweak the
> impacted Solr APIs to propogate the (remaining) {{timeAllowed}} (if that
> option was specified) down to this class – and/or have an "extreme" default
> (ie: 30min) just to prevent threads from sticking around forever.
