Subject [jira] [Resolved] (HTTPCORE-402) impossible to close a ChunkedInputStream.
Date Sat, 02 May 2015 15:21:06 GMT

Oleg Kalnichevski resolved HTTPCORE-402.
    Resolution: Invalid

Content stream #close method is not meant to close the underlying connection. There is nothing
stopping you from shutting the connection, though, if that is what you want.

>                 Key: HTTPCORE-402
>                 URL: https://issues.apache.org/jira/browse/HTTPCORE-402
>             Project: HttpComponents HttpCore
>          Issue Type: Bug
>          Components: HttpCore
>    Affects Versions: 4.3.3
>            Reporter: James Nord
>            Priority: Critical
> If you have a server that will just send Chunked output for streaming then it is impossible
to close the ChunkedInputStream correctly.
> When calling close - it will helpfully try to read until the server sends the terminating
chuck - but if this is never going to arrive (as is the case with Docker and many other servers
that send notification updates via chunking)  the close method never returns and goes into
a loop reading and throwing away every single chunk.
> Whilst is is a worthy aim of not keeping the connection overhead low - if you want to
close a stream you want to close it.  Chunks, pipelining or anything else don;t matter and
you want to close things for a reason.
> In this case it prevents users from ever closing a HTTP connection so it is never available
for re-use in any case.
> see https://github.com/docker-java/docker-java/issues/196 for a real life example of
why this is bad.
