Issue Type: Bug
Components: Components

Environment: RedHat Enterprise Linux 5 (SMP Kernel 2.6.18)
Apache Tomcat 6.0.14
tomahawk 1.1.6
trinidad 1.2.2
JDK 6:
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Server VM (build 1.6.0_02-b05, mixed mode)

Same behavior on Windows XP Pro SP2 with same Tomcat, JDK, and libraries
Reporter: Jonathan Schwehm
We've noticed an issue with the default uploaded-file-processor on both Windows
and Linux machines in the file upload part of our web application. When a user
uploads a file that's larger than UPLOAD_MAX_MEMORY, the
UploadedFileProcessorImpl creates a temporary file. If UPLOAD_TEMP_DIR is not
specified, these files are going into
<tomcathome>/work/Catalina/localhost/<webapp>.
The issue is that these temporary files aren't being removed. On our Linux
machines, they are usually removed when tomcat is stopped. On Windows, more
often than not they continue to persist.
When the UPLOAD_TEMP_DIR is specified, the temporary files are placed in that
folder, but are still not deleted. I've ensured on our Linux machine that the
temporary folder has full permissions for all and the temporary files are owned
by the same user that runs Tomcat. We've even run Tomcat as root with the same
results. The temporary file is created similar to this one: -rw-r--r-- 1 root
root 857154 Mar 18 00:15 uix50712.tmp
Here's the portion of our web.xml that configures the uploaded-file-processor:
<context-param>
<!-- Maximum memory per request (in bytes) -->
<param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_MEMORY</param-name>
<!-- Use 500K -->
<param-value>512000</param-value>
</context-param>
<context-param>
<!-- Maximum disk space per request (in bytes) -->
<param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE</param-name>
<!-- Use 5,000K -->
<param-value>102400000</param-value>
</context-param>
<context-param>
<param-name>org.apache.myfaces.trinidad.UPLOAD_TEMP_DIR</param-name>
<param-value>/tmp/</param-value>
</context-param>
