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

I'm glad you got that working. That's a 32-bit system, isn't it? Looks
like you got bit by this bug:

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! :-)

Hi Krzysztof,

I found something highly relevant to my issue:
http://lists.unbit.it/pipermail/uwsgi/2014-June/007389.html

So I followed Roberto's suggestion and removed my __pycache__ dir but the
issue is persisting.

What do you think? Should i attempt to patch pypy_setup.py ?

Yes, this looks like sensible next step.

But just to be sure, before you do that, confirm that your nginx is
correctly sending REQUEST_METHOD header to 127.0.0.1:8000.
