Failed to Debug under WingIDE for setting “app.debug = True”

[honglei]

Windows8/Python2.7 64bit/WingIDE, using the build-in example in Flask-SocketIO.
I found that when using WingIDE, the breakpoints I set does not work.
Reason: flask_socketio/init.py run() invoked run_with_reloader(), whick make another python.exe process.
So I comments the 'app.debug = True' line, and all breakpoints become OK.

app = Flask(__name__)
#app.debug = True
app.config['SECRET_KEY'] = 'dosjfsodfa097324r3rn09dv66s8839bd'
socketio = SocketIO(app)
thread = None

Yes, debugging with the reloader enabled gets tricky because the application runs in a child process. An improvement that I could make is to support the use_reloader argument in run(), like Flask's app.run() does. That will let you run in debug mode without the reloader.

I found that without being able to pass use_reloader to socketio.run(), I couldn't run unit tests using selenium in the way suggested in the Flask book. WerkZeug tries to reload the executable "python -m unittest".

Maybe I'm missing something about how to do this? If not I would strongly support this enhancement being made.

Are you running your unit tests with debug=True? You should have debug=False when you run your tests.

Sorry about this! I have correctly added debug=False to the above and it now works.

Thanks a lot, sorry to report problems prematurely. I have removed a couple of previous comments where I still hadn't figured out where my mistake was.
