wsgi request fails if the request contains HTTP_CONTENT_LENGTH

[raptium]

wsgi.py reads content_length string from environ['HTTP_CONTENT_LENGTH'] and never converts it into int.

Traceback (most recent call last):
  File "/home/hguan/Desktop/raad/www/wsgi.py", line 34, in application
    return tornado_application(environ, start_response)
  File "/home/hguan/Desktop/raad/www/tornado/wsgi.py", line 77, in __call__
    handler = web.Application.__call__(self, HTTPRequest(environ))
  File "/home/hguan/Desktop/raad/www/tornado/wsgi.py", line 116, in __init__
    self.headers["Content-Length"])
TypeError: an integer is required

Actually Content-Length is first read from environ['CONTENT_LENGTH'] and it gets converted into int. However, if HTTP_CONTENT_LENGTH also presents, it will overwrite self.header['Content-Length'] with a str.

if environ.get("CONTENT_LENGTH"):
    self.headers["Content-Length"] = int(environ["CONTENT_LENGTH"])
for key in environ:
    if key.startswith("HTTP_"):
        self.headers[key[5:].replace("_", "-")] = environ[key]
if self.headers.get("Content-Length"):
    self.body = environ["wsgi.input"].read(
        self.headers["Content-Length"])
