pydev - remote debugging issue

[Zbyněk Fiala]

Hi,
thanks for LiClipse, I am testing it now and I have to say finally decent solution for my python scripting adventure.

I would like to kindly ask for any help with  remote debug issue:

I am using LiClipse + PyDev for remote debugging Kodi script in python. I am able to debug fully (watches, breakpoints,variables ...) any plugin,
but only one time. Another attempt for debugging resulting in

Error Type: <type 'exceptions.RuntimeError'>
                                            Error Contents: classes are read-only in restricted mode
                                            Traceback (most recent call last):

Thanks for any clarification

I think the issue you're having is that the module you're using is using Python in restricted mode (https://docs.python.org/2/library/rexec.html)... 

I don't think there's much that can be done in PyDev -- that functionality of Python itself seems to be deprecated (since 2.6 and removed in Python 3) and the debugger doesn't really support it (i.e.: apparently it's not even possible to set attributes in classes) -- I must say I'm really surprised it worked the first time given that there are probably lots of restrictions on restricted mode.

What you can try to do is changing the code locally to work around the issues it may have to see if you can get farther (i.e.: remove the .pyd files generated on folders below e:\Program Files\Brainwy\LiClipse 3.1.0\plugins\org.python.pydev_5.2.0.201608171655\pysrc\ and treat the exceptions you have in the .py files because of the restricted mode).

Cheers,

Fabio

Thanks for info.
I appreciate your fast response.
I will try to cope with it in my code.

Just adding a little bit of history:
1. PyDev 5.2 - pyscr in default path in LiClipse
 Remote connection established: OK
 Stop after settrace: OK
 Add breakpoint insertion: OK
 but only for the first addon launch another attempt threw:

LiClipse 3.1.0\plugins\org.python.pydev_5.2.0.201608171655\pysrc\pydevd_tracing.py", line 77, in SetTrace

TracingFunctionHolder._warn = False RuntimeError: classes are read-only in restricted mode

2. Pydev 5.2 + script.module.pydev from https://github.com/powlo/script.module.pydevd compatible with PyDev 3.4.2
 Remote connection established: OK
 Stop after settrace: OK
 Add breakpoint insertion: NOK threw:

Kodi\addons\script.module.pydevd-master\lib\pydevd.py", line 878, in processNetCommand
21:57:49 T:8048   ERROR:     thread_id, frame_id, console_command = text.split('\t', 2)
21:57:49 T:8048   ERROR: ValueError: need more than 1 value to unpack

3. Pydev 5.2 + script.module.pydev from https://github.com/nabilbendafi/script.module.pydevd compatible with PyDev 4.4.0
 Remote connection established: OK
 Stop after settrace: OK
 Add breakpoint insertion: OK
 works like a charm  not only once
