ue4-socketio-crash

Test project for demonstrating crash on SocketIO in UnrealEngine 4.15.2 using Flask-SocketIO.

Requirements

• Python 2.7
• (Windows only) Install the VC++ compiler for Python 2.7 (http://www.microsoft.com/en-us/download/details.aspx?id=44266)

Install instructions

1. Download PyCharm (https://www.jetbrains.com/pycharm/download/) - Community Edition is sufficient

2. Open this repository

3. Set interpreter to Python2.7

   1. Go to "File" -> "Settings"
   2. Search for "Interpreter"
   3. Set to Python 2.7

4. Open ue-crash-dummy.py

5. PyCharm should now display that some requirements are missing -> click "Install requirements"

Steps to reproduce

1. In UnrealEngine 4 create a SocketIO client

   1. Connect to Address and Port: ws://localhost:5000

2. Emit the following event: testEvent

   1. UnrealEngine should crash

3. Restart UnrealEngine

4. Emit the following event: testEventWithException

   1. In this event I raise an Exception within the event in Python. This (at least that's what I guess) causes the server to not return anything
   2. UnrealEngine should not crash
