What is the recommended way to exit hard from a script in the event of an error? I triggered an error by introducing a nonsense line and can see the printout for it, but the process stays up even after the error:
Script error: Traceback (most recent call last):
File "/gateway_mitmproxy_script.py", line 93, in tcp_message
deliberate_syntax_error = foo
NameError: name 'foo' is not defined
The reason that I ask is that I’m running mitmproxy in a docker container that is being watched by another process, and I would like the docker container to exit when there is an error in the script.
This is currently more or less intended behavior as we want you to be able to live-edit a mitmproxy script. We automatically pick up changes to scripts while mitmproxy is running. Temporary syntax errors are a common occurence in that case and shouldn’t exit mitmproxy right away. I’m not sure what happens if the script is invalid right away, but I’d certainly be happy to accept a PR that makes mitmproxy fail right away in that case.
Thank you for clarifying! Sounds like maybe a good PR would be to have a command line option on mitmdump that changes the default failure behavior - I’ll think it over.
