I am seeing some very suprising behavior with calling ->upload on a Apache2::Request object (with use Apache2::Upload). It appears that if the user did not click and select a file to upload, that is to say left the <input type="file" ...> field empty, the server stops processing the perl code and immediately sends a response to the browser with whatever it has so far. No error message appears in the error log.
It appears that this happens if *any* file field is left un-filled, that is to say, ->upload("file1") will silently die even if file1 was specified, if file2 was left un-filled.
I have written up a description and replication code here: http://back.nber.org/sys-admin/apache2_upload_bug.html Is this something anyone else has seen? Thanks, - Alex Aminoff NBER
