Add the ability to enforce a maximum attachment size
----------------------------------------------------
Key: CXF-3879
URL: https://issues.apache.org/jira/browse/CXF-3879
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 2.4.3, 2.3.7, 2.2.12
Reporter: Sam Meder
Safe handling of multipart-* HTTP request requires the ability to cap the size
of the uploaded attachments before they get cached. CXF does currently not
provide an option for this (other frameworks such as the commons fileupload and
the 3.0 servlet spec do provide this). I've attached a quick patch that allows
one to set a option for enforcing a size limit while doing the attachment
parsing (similar to the threshold and temp dir options). The biggest question
imo is how to best bubble up a appropriate error. I chose to subclass
IOException and then later on transform it into a 413 (request size too large)
HTTP response, but would welcome input on other approaches.
I will attach a patch against CXF 2.2, but believe that it should also apply to
newer versions.
