Tried using this with my project, with venv, installed with pip install heartrate, this is the error I get:

$ python main.py

This is the stacktrace in the browser window:

/usr/lib/python3.7/threading.py : 1308 : _shutdown
    lock.acquire()

My code can be found here, I just added import heartrate; heartrate.trace(browser=True) in main.py, line 2.

Whoops, I had some unreleased code. Upgrade and try again.

[mendelmaleh]

Upgraded and it works, thanks. There are another two issues tho:

1. my program uses trl+c to shutdown, i guess flask too uses that so now its broken
2. i had to shut it down with ctrl+z instead, and when i started it up again it gave

   File "/usr/lib/python3.7/socketserver.py", line 466, in server_bind
   self.socket.bind(self.server_address)
   OSError: [Errno 98] Address already in use

[alexmojaki]

Both flask and your program should respond to ctrl+c and shut down, although you may need to press it a few times. What exactly happens when you press ctrl+c?

Ctrl+z doesn't shut down, it suspends. So the old process wasn't dead. If nothing else works you will need to find the process ID and kill (maybe kill -9) it.

[mendelmaleh]

So, after the first ctrl+c it shows this in the stacktrace:

/usr/lib/python3.7/threading.py : 1308 : _shutdown
            lock.acquire()

In the terminal it it just shows '^C' (normal), no output from python. The program does stop working, however heartrate still works (can still be reloaded at least).

Doing ctrl+c multiple times doesn't do anything.

[alexmojaki]

I reproduced this, but I couldn't figure out why it doesn't respond to Ctrl+C. Maybe something to do with asyncio?

I added https://github.com/alexmojaki/heartrate/commit/cf9496df5080a3ce9928939d78a55928ea0d3491 as a workaround. Upgrade and use trace(daemon=True) and the server will shutdown when the program ends (e.g. when you press Ctrl+C).
