Running flask + gevent + requests not serving 'concurrently'
flask, gevent, io, python
Solution
I believe the issue is likely that you forgot to monkey patch. This makes it so that all of the normally blocking calls become non-blocking calls that utilize greenlets. To do this just put this code before you call anything else.
from gevent import monkey; monkey.patch_all()
Go to http://www.gevent.org/intro.html#monkey-patching for more on this.
Problem
I kick off my flask app like this: ``` #!flask/bin/python from app import app_instance from gevent.pywsgi import WSGIServer #returns and instance of the application - using function to wrap configuration app = app_instance() http_server = WSGIServer(('',5000), app) http_server.serve_forever() ``` And then when I try to execute this code, the requests call blocks until the original request times out. I'm basically invoking a webservice in the same flask app. What am I misunderstanding about gevent? Wouldn't the thread yield when an i/o event occurred? ``` @webapp.route("/register", methods=['GET', 'POST']) def register(): form = RegistrationForm(request.form, csrf_enabled=False) data = None if request.method == 'POST' and form.validate(): data= {'email': form.email, 'auth_token': form.password, 'name' : form.name, 'auth_provider' : 'APP'} r = requests.post('http://localhost:5000', params=data) print('status' + str(r.status_code)) print(r.json()) return render_template('register.html', form=form) ```
