Using Apache 2.4.29, mod_wsgi 4.5.24 and Python 3.6.4. I serve big files using WSGI and an iterator. When the client closes the connection BEFORE the file is completed, an error 500 is logged in Apache, without any indication of the issue or how to solve it.
I have a minimal testcase:
1. Apache configuration: Inside a virtualhost I do this:
"""
WSGIDaemonProcess test threads=16 display-name=%{GROUP}
python-path=/home/buffy/ home=/home/buffy/ stack-size=524288
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup test
WSGIScriptAlias /test /home/buffy/z.py
<Location /test/>
require all granted
</Location>
"""
2. The WSGI application "/home/buffy/z.py" is quite trivial:
"""
class app:
def __init__(self, environ, start_response):
start_response('200 OK',
[('content-type', 'application/octet-stream')])
def __iter__(self):
while True:
yield b'W'*4096
def application(environ, start_response) :
return app(environ, start_response)
"""
Any request inside "/test/" with wget or similar will generate an
infinitely long file. Just do a random request with "wget", let it go
for a couple of seconds (the file size if unbounded, beware) and abort
"wget" with control+c.
What I get: An error 500 in my Apache virtualhost access log. Nothing in
the error log.
What I would like to get: a 200 in my Apache virtualhost access log.
What am I doing wrong?. A "def close(self): pass" doesn't change
anything. Suggestions?.
