Problems with debuggers (ipdb/pdb)

[dangusev]

Hi! Hug is awesome, thank you!
But I have a problem with ipdb/pdb debugger in api. When I try to use them in endpoints I have exceptions.
I use python 3.6.1, hug 2.3.0

For example:

@hug.get('/test/ipdb/')
def test_ipdb():
    import ipdb; ipdb.set_trace()

curl localhost:8000/test/ipdb/


--Return--
None
> /home/dan/projects/flowy/flowy/api/entrypoint.py(15)test_ipdb()
     14 def test_ipdb():
---> 15     import ipdb; ipdb.set_trace()
     16 

ipdb>

Hi @dangusev,

This is a problem caused by the auto re-loader, you can bypass it for now by running with the --manual_reload option, long term it should be fixed to allow PDBs while auto reload is enabled.

Thanks!

This should be fixed in the latest release to work without any extra options.

Thanks!
