FileUploadInterceptor does not clean up temporary files
-------------------------------------------------------
Key: WW-3801
URL: https://issues.apache.org/jira/browse/WW-3801
Project: Struts 2
Issue Type: Bug
Components: Core Interceptors
Affects Versions: 2.3.1.2, 2.2.3
Environment: JDK 1.6.0_31, Tomcat 7.0.25
Reporter: macha64
Priority: Minor
In WW-3490, it solved "clean up exception" issue.
then clean up code went to FilterDispatcher.
but FilterDispatcher is deprecated.
I usually use StrutsPrepareAndExecuteFilter.
in that case temporary file was not removed.
I found another problem.
I uploaded file with cgi parameters.
cgi parameter became a temporary file,
and those files were not removed.
for example ...
<form action="..." method="post" enctype="multipart/form-data">
<input type="file" name="uploadFile" />
<input type="text" name="data1" value="FOO"/>
<input type="text" name="data2" value="BAR"/>
</form>
remained tmp file
[upload_47c7ddf7_136bf8a8b3b__8000_00000002.tmp]
FOO
[upload_47c7ddf7_136bf8a8b3b__8000_00000003.tmp]
BAR
