bufferSize in controller configuration does not work
----------------------------------------------------
Key: STR-3096
URL: https://issues.apache.org/struts/browse/STR-3096
Project: Struts 1
Issue Type: Bug
Components: Core
Affects Versions: 1.3.9
Environment: simple struts web application with file-upload feature
Reporter: AdNovum
Priority: Minor
Controller configuration allows to set a buffer size to be used when doing file
uploads (described in online documentation):
<controller
className="..."
processorClass="..."
inputForward="true"
bufferSize="102400"
>
...
Unfortunately it seems that this value is never propagated to the
implementation classes (CommonsMultipartRequestHandler, DiskFileUpload and
FileUploadBase)
from struts and apache commons-fileupload. So the default buffersize (4K) is
used which could possibly lead to bad performance (high CPU usage).
Either the bufferSize should take effect or it should not be available as a
configuration attribute.
