James Nord created HTTPCORE-402:
-----------------------------------
Summary: impossible to close a ChunkedInputStream.
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.
