Large file uploads

[Recital Recital]

I am using the standard recipe for large file uploads.

class Update:

    def POST(self, name=''):

        params = web.input(filedata={})

...

The call web.input(filedata={}) seems to instantiate a dictionary with the contents of the file from the multipart POST.

I am running on an embedded system and do not have adequate memory or swap area to load the file in memory

The operation breaks with a pipe error on the lighttpd side.

Is there any way to force the call to not load all the data.

It seems to be read from a file descriptor on the storage operation.

with open(update_path, 'wb') as fp:

            fp.write(params.filedata.file.read())

Thanks
