Note that the first example could be a infinitive loop, where it does
not get to the return statement, never the less prints should show
up ?
# WEB OUTPUT
# LOG OUTPUT
import os,sys
def application(environ, response):
print('STDERR %s' % __file__, file=sys.stderr)
#query=environ.get['QUERY_STRING']
query=os.path.join(os.path.dirname(__file__),'teeeeeeeeeemp')
print('test',file=environ['wsgi.errors'])
range=environ.get('HTTP_RANGE','bytes=0-').replace
('bytes=','').split(',')
offset=[]
for r in range: offset.append(r.split('-'))
with open(query,'wb') as f
f.seek(offset[0][0])
while True:
chunk=environ['wsgi.input'].read(8192).decode('latin1')
if not chunk: break
f.write(chunk)
l=os.fstat(f.fileno()).st_size
response('200 OK', [('Content-Type', 'text/plain'), ('Content-
Length', str(len(l)))])
return [l]
#500 Internal Server Error

def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'
print('STDERR %s' % __file__, file=sys.stderr)
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
#Hello World!

def application(environ, start_response):

output = str(sys.stderr)
print('STDERR %s' % __file__, file=sys.stderr)
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)

Ps did you read the other post about chunk transfer or was the
question not clear like this one ?
