Re: [uWSGI] PyPy issue

[Etienne Robillard]

Hi Kryzsztof,

Thank you for your kind reply. Yes, i'm running a 32-bit machine for 
development purpose.


My patch is working for my simple use-case but i believe it is far from 
being perfect.


However, i'm not exactly sure how to implement the proposed workaround.

Any chances this is going to be fixed in a future uWSGI release ?


Best regards,

Etienne

OK. I got a working patch:

for i in range(0, iov.iov_len, 1):
   environ[ffi.string(ffi.cast("char*", iov[i].iov_base),
iov[i].iov_len)] = ffi.string(ffi.cast("char*", iov[i+1].iov_base),
iov[i+1].iov_len)

if not 'SERVER_NAME' in environ:
 environ['SERVER_NAME'] = uwsgi.hostname
if not 'SERVER_PORT' in environ:
  environ['SERVER_PORT'] = 80

It's ugly but it works! :-)

As a side-effect, i needed to add my hostname to ALLOWED_HOSTS.

Not really sure why SERVER_NAME and SERVER_PORT are not included in the
environ dict.

What do you think?

Hi,

I confirm nginx is really sending the REQUEST_METHOD header with
nginx/uwsgi:

04:33:37.008721 read(6,
"\0\274\1\0\f\0QUERY_STRING\0\0\16\0REQUEST_METHOD\3\0GET\f\0CONTENT_TYPE\0\0\16\0CONTENT_LENGTH\0\0\v\0REQUEST_URI\v\0/benchmark/\t\0PATH_INFO\v\0/benchmark/\r\0DOCUMENT_ROOT!\0/home/erob/www/isotopesoftware.ca\17\0SERVER_PROTOCOL\10\0HTTP/1.1\v\0REMOTE_ADDR\t\000127.0.0.1\v\0REMOTE_PORT\5\00041286\v\0SERVER_PORT\2\00080\v\0SERVER_NAME\t\0localhost\v\0REMOTE_USER\0\0\v\0SCRIPT_NAME\0\0\7\0HTTP_TE\22\0deflate,gzip;q=0.3\17\0HTTP_CONNECTION\t\0TE,

libwww-perl/6.15", 4100) = 448

So I tried to hack pypy_setup.py by using iov.iov_len as a replacement for
wsgi_req.var_cnt and here's the result:

  environ = {}
  iov = wsgi_req.hvec
  for i in range(0, iov.iov_len, 2):

 environ[ffi.string(ffi.cast("char*", iov[i].iov_base),
iov[i].iov_len)] = ffi.string(ffi.cast("char*", iov[i+1].iov_base),
iov[i+1].iov_len)

Now the traceback is somewhat different. Progress! :-)
