How Do You Thread an External Hanging API Call in Flask?

Getting the specifics out of the way, I'm writing an open source P2P social network over IPFS and Flask -- I know, it's been done. I'm choosing Flask because pyinstaller can put it in an exe file.
I am attempting to update my IPNS every 10 minutes to publish all status updates I've added to the network during said 10 minutes. The cron function from setup class (from library.py) is where that updater function is stored. At first, I threaded the cron function from init of setup. The server hung. Then I moved the threading process over to app.before_first_request. The server still hangs.

I have searched the web for a couple days and have yet to find a threading technique that will split from the main process and not hang the server from taking other requests. I believe I'm on a single stream connection, as IPFS blocks connections to every other device in my home when it's started. It takes a couple minutes for the CLI IPNS update to go through, so I set urllib's timeout to 300 seconds.

Well what I think the threading code is not correct.
#app.before_first_request
def cron_job():
Thread(target=GANN.cron())
Here you created a Thread object. The argument must be callable, but you called your method already here. so the right way would be
Thread(target=GANN.cron)
So the thread can call the cron function later. having said that, the Thread must be started, so it will call the function target you gave. So it must be ike
thread_cron = Thread(target=GANN.cron)
thread_cron.start()
Since you called the GANN.cron() , the method starts executing and your app hung!

How to enable selenium webdriver to work with Python remote objects (Pyro) in a bokeh document?

I have a python document running in bokeh server with bokeh serve view_server_so.py --show. The webpage is immediately opened in a browser tab.
For testing purposes I am using Pyro to allow remote access to some of the objects / methods running in the bokeh server.
My server testscript creates just one button and one method (exposed to remote control), bokeh serves the webpage on http://localhost:5006/view_server_so.
The button is a Toggle button, each time the button is pressed its active state alternates between True and False, and its color changes.
# view_server_so.py
# This script shall be started from the command line with
# bokeh serve view_server_so.py --show
from bokeh.layouts import layout, row
bokeh.models import Toggle
from bokeh.io import curdoc
import os
import Pyro4
import socket
import subprocess
import threading
# The layout used in the html-page
class View():
def __init__(self):
self.document = curdoc()
self.btn_task = Toggle(label="Press me",
button_type="success",
css_classes=["btn_task"])
self.layout = layout(row(self.btn_task))
#Pyro4.expose
def get_btn_task_active_state(self):
# This method is enabled for remote control
# The btn_task changes its active state each time it is pressed (bool)
print('active state: {}'.format(self.btn_task.active))
return self.btn_task.active
# As the script is started with 'bokeh serve',
# bokeh has control of the main event loop.
# To enable Pyro to listen for client requests for the object view,
# and its exposed method,
# the Pyro event loop needs to run in its own thread.
class PyroDaemon(threading.Thread):
def __init__(self, obj):
threading.Thread.__init__(self)
self.obj=obj
self.started=threading.Event()
print('PyroDaemon.__init__()')
def run(self):
daemon=Pyro4.Daemon()
obj = self.obj
self.uri=daemon.register(obj,"test")
self.started.set()
print('PyroDaemon.run()')
daemon.requestLoop()
view = View()
print('view created')
# starting a Pyro name server
hostname = socket.gethostname()
print('hostname: {}'.format(hostname))
try:
print('try Pyro4.locateNS()')
name_server=Pyro4.locateNS()
except Pyro4.errors.NamingError:
print('except Pyro4.errorsNamingError')
args = ['python', '-m', 'Pyro4.naming', '-n', hostname]
p = subprocess.Popen(args)
name_server=Pyro4.locateNS()
print('Nameserver is started')
# create a pyro daemon with object view, running in its own worker thread
pyro_thread=PyroDaemon(view)
pyro_thread.setDaemon(True)
pyro_thread.start()
pyro_thread.started.wait()
print('Daemon is started')
# The object view is registered at the Pyro name server
name_server.register('view', pyro_thread.uri, metadata = {'View'})
print('view is registered')
view.document.add_root(view.layout)
Now I have a second testscript. After some setup for the remote object, it simply calls several times the method get_btn_task_active_state() and prints the result. When between the calls the button is clicked in the browser, the active state switches and is correctly printed.
import Pyro4
import time
# looking for the Pyro name server created in view_server_so.py
nameserver=Pyro4.locateNS(broadcast = True)
# get the URI (universal resource identifier)
uris = nameserver.list(metadata_all = {'View'})
# create a proxy object that interacts (remote control)
# with the remote object 'view'
view_rc = Pyro4.Proxy(uris['view'])
for i in range(3):
time.sleep(3)
# change the state manually: click on the button
print('state: {}'.format(view_rc.get_btn_task_active_state()))
# prints
# state: False
# state: True
# state: False
As manual testing gets tedious, I want to automate the manual clicks to the button. So I am adding webdriver support, look up the button in the webpage, and have some automated clicks and the calls to get_btn_task_active_state() as before.
import Pyro4
from selenium import webdriver
import socket
import time
# looking for the Pyro name server created in view_server_so.py
nameserver=Pyro4.locateNS(broadcast = True)
# get the URI (universal resource identifier)
uris = nameserver.list(metadata_all = {'View'})
# create a proxy object that interacts (remote control)
# with the remote object 'view'
view_rc = Pyro4.Proxy(uris['view'])
# use the Chrome webdriver
driver = webdriver.Chrome()
# open a Chrome Browser and the given webpage
driver.get("http://localhost:5006/view_server_so")
time.sleep(1)
# Find the button
btn_task = driver.find_element_by_class_name("btn_task")
for i in range(3):
time.sleep(1)
print('state: {}'.format(view_rc.get_btn_task_active_state()))
btn_task.click()
# prints
# state: False
# state: False
# state: False
#
# but should alternate between False and True
An webdriver controlled browser opens, I can see the color of the button change visually as it is automatically clicked, but the active state of the button does not seems to change any more.
What changes would be necessary, so that the automated script gives the same results as the manual testing?

Selenium Webdriver Chrome creating to many Threads

i'm having some trouble about this WallBoard webapp (Python) that i have to fix, i hope i can be very clear of what the problem is so its easy for you to understand and help me.
So, the app has 3 pages, Main Page, Calls Waiting, Tickets. It is used by support team in this company to track calls of the day and tickets too.
So when i run this app with VS Code, its behavior is absolutely normal. App logs to another website to retrieve calls information, and Database to retrieve Tickets information. After some time session expires (retrieving calls information) but app detects and logs in again.
When i start the app at IIS(8.5) EVERY 17min the app gets restarted for no reason, and after a few hours of this i have 40 to 50 Google Chrome Threads taking all my memory from the machine it is hosted in...
I don't believe it is a problem with IIS, i think it is responding like this for some reason and i can't find out.
Here is the code for the WallBoard App

# Start scheduler
sched.start()
with open('log.txt', 'a') as f:
print('WallBoard Started! - ' + str(datetime.now()), file=f)
if __name__ == "__main__":
app.run()
So at this point i'm completely lost, i have done hours of research trying to find what the problem is but still no luck.
I took out the code inside because it was too big but if necessary i can provide it.
I was using PhantomJS but i was always getting the Warning that is deprecated and i decided to change do ChromeDrive but the problem still remains.
Can it be with BackgroundScheduler? because i'm starting to think that each time IIS force the app to restart, it creates more Jobs and doesn't kill the others.
I appreciate all the help and tips, and i am really sorry for this long post!
I took this screenShot after 10min of running, i will update with new one in the morning

Python - Mysterious Double Object Instantiation [duplicate]

This question already has answers here:
Why does running the Flask dev server run itself twice?
(7 answers)
Closed 5 years ago.
I am running into a seemingly bizarre problem that I can't figure out - I am trying to create a single object, however for some reason, two are always made.
The two files control a robot i am building.
App.py
A flask server which receives in coming commands through a socket.io connection with clients
Hypervisor.py
Robot Controller, takes in user commands, sensor data, current agenda, and feeds commands to the MotionController.
I am trying to create a single instance of a the Hypervisor class from within the Flask server app.py, however two are consistently created.
Below is my code and console output showing the double object creation. Why is this happeneing!!?!?!?

First of all a little soapboxing:
If you provide a SSCCE (Short, Self-Contained, Correct (Compilable), Example) then you are more likely to get a response. Also by trimming the example to the minimum required to reproduce you may very well identify the source of the problem yourself. For example the following would be a SSCCE for your issue:
Required dependancies:
pip install flask
pip install flask-socketio
Code:
import logging
from flask import Flask
from flask_socketio import SocketIO
logging.basicConfig(level=logging.ERROR)
app = Flask(__name__)
socketio = SocketIO(app)
class Hypervisor():
def __init__(self):
print('Hypervisor initialized')
if __name__ == '__main__':
quadbot = Hypervisor()
socketio.run(app, debug=True)
Output:
Hypervisor initialized
Hypervisor initialized
Explanation
If you use a debugger the answer presents itself fairly easily. You can use the debugger tools included in your IDE, or you can always use The Python Debugger from the python standard library (a.k.a. pdb).
While it's beyond the scope of this answer to provide a complete tutorial of pdb, the method we will use to debug is to break into the debugger by importing pdb and inserting the following pdb.set_trace() at the point you want to begin debugging.
Since the issue is with Hypervisor creation the logical point to insert the debugger is just before the initialization of Hypervisor like so:
if __name__ == '__main__':
import pdb
global quadbot
pdb.set_trace() # debugging begins here
quadbot = Hypervisor()
socketio.run(app, debug=True)
From this point when you run your app, it will drop into pdb right before the initialization of Hypervisor. Before you do so though, you will need to know two commands for using pdb.
The first is n for next which continues execution until to the next line of code in the current function.
The second is s for step which will step into the current code stopping at first opportunity.
Or as the docs explain it:
The difference between next and step is that step stops inside a called function, while next executes called functions at (nearly) full speed, only stopping at the next line in the current function.
So armed with this knowledge run your app, and you will be presented with the pdb prompt which should look something like this:
-> quadbot = Hypervisor()
(Pdb)
The -> shows the current line of code about to be executed. (Pdb) is the prompt awaiting input. At this point let's initialize the Hypervisor by proceeding to the next line of code by typing n and enter. At this point you should see a single Hypervisor has been created.
[4/3/2017 20:02:46 ] Hypervisor: __init__() finished. Robot Created with id 4218654299
And be returned to the pdb prompt for the next line:
-> socketio.run(app, debug=True)
(Pdb)
So since there's only one more line of code left to run, the issue is somewhere in socketio.run. So this time we will step into the current line of code by typing s and enter which will bring you to:
-> def run(self, app, host=None, port=None, **kwargs):
(Pdb)
From this point, keep stepping to the next line of code until you see the second Hypervisor initialization. Looking at the trace you should see something like the following:
-> app.run(host=host, port=port, threaded=True,
(Pdb) n
-> use_reloader=use_reloader, **kwargs)
(Pdb) n
-> quadbot = Hypervisor()
(Pdb) n
[4/3/2017 20:03:52 ] Hypervisor: __init__() finished. Robot Created with id 4367452293
This shows you that right after the app.run executes (it takes two n's to execute since the command spans two lines of code), it returns to the quadbot = Hypervisor() line of code we started at. So a closer look at app.run shows an argument called use_reloader. If you haven't guessed already, looking at the Flask-SocketIO docs tells us:
use_reloader - True to enable the Flask reloader, False to disable it.
With a little more digging we can find the following two nuggets of wisdom in the Flask docs:
debug
The debug flag. Set this to True to enable debugging of the application. In debug mode the debugger will kick in when an unhandled exception occurs and the integrated server will automatically reload the application if changes in the code are detected.
and
run...
Flask will suppress any server error with a generic error page unless it is in debug mode. As such to enable just the interactive debugger without the code reloading, you have to invoke run() with debug=True and use_reloader=False. Setting use_debugger to True without being in debug mode won’t catch any exceptions because there won’t be any to catch.
So armed with this information you can choose to either disable debug, or pass the option use_reloader=False to socketio.run.
TL;DR
You most likely want to disable the Flask reloader by passing use_reloader=False to socketio.run
if __name__ == '__main__':
global quadbot
quadbot = Hypervisor()
socketio.run(app, debug=True, use_reloader=False)

How to install a Python Windows service using cx_Freeze?

I currently have a Python file that when run using python file_name.py installs a Windows service that is viewable in Event Viewer under application logs and stoppable using sc stop service_name. However, when converted into an executable using cx_Freeze, the executable runs with no errors but the service no longer installs. This happens if I run just the executable by itself, if I run service_name.exe --install service_name, or if I run sc create service_name binPath=service_path
My setup.py file looks something like:
from cx_Freeze import setup, Executable
options = {
'build_exe': {
'packages': ['packagename'],
'includes': ['ServiceHandler', 'cx_Logging']}
}
setup(name='cx_FreezeSampleService',
version='0.1',
description='Sample cx_Freeze Windows serice',
executables=Executable('Config.py', base='Win32Service',
targetName='cx_FreezeSampleService.exe'),
options=options
)
My Config.py looks something like:
NAME = 'cx_FreezeSampleService%s'
DISPLAY_NAME = 'cx_Freeze Sample Service - %s'
MODULE_NAME = 'ServiceHandler'
CLASS_NAME = 'Handler'
DESCRIPTION = 'Sample service description'
AUTO_START = True
SESSION_CHANGES = False
And finally, my ServiceHandler.py looks something like:
class Handler(object):
def Initialize(self, Config):
pass
def Run(self):
#code to run service
def Stop(self):
#code to stop service
This code follows the example at the cx_Freeze source code here (https://bitbucket.org/anthony_tuininga/cx_freeze/src/1282b6b6ee637738210113dd88c3c198d475340f/cx_Freeze/samples/service/?at=default) almost exactly, but neither this nor the example seem to work in actually installing a service.
Thank you in advance!

This is an old question, but I manage to get it working as a window service for a simple flask application with the help of the developers.
[https://github.com/marcelotduarte/cx_Freeze/tree/master/cx_Freeze/samples/service]
You have to set up all the windows service actions you want performance.
this is how the ServiceHandler.py should look like as a template you still need to adapt to run your application.
