I learn this on GitHub Gist the opposite day. I don’t know whether or not I’ll ever use it however I’m nonetheless placing this on my weblog for the sake of bookmarking it. Who is aware of? Somebody from the viewers may find yourself utilizing it!
I screwed up utilizing git (
git checkout – on the flawed file) and managed to delete the code I had simply written… however it was nonetheless operating in a course of in a docker container. Right here’s how I acquired it again, utilizing pyrasite and uncompyle6
Connect a shell to the docker container
Set up GDB (wanted by pyrasite)
apt-get replace && apt-get set up gdb
Set up pyrasite – this may allow you to connect a Python shell to the still-running course of
pip set up pyrasite
uncompyle6, which is able to allow you to get Python supply code again from in-memory code objects
pip set up uncompyle6
Discover the PID of the method that’s nonetheless operating
ps aux | grep python
Connect an interactive immediate utilizing pyrasite
Now you’re in an interactive immediate! Import the code it’s essential get well
>>> from my_package import my_module
Work out which features and courses it’s essential get well
>>> dir(my_module) ['MyClass', 'my_function']
Decompile the operate into supply code
>>> import uncompyle6 >>> import sys >>> uncompyle6.foremost.uncompyle( 2.7, my_module.my_function.func_code, sys.stdout ) # uncompyle6 model 2.9.10 # Python bytecode 2.7 # Decompiled from: Python 2.7.12 (default, Nov 19 2016, 06:48:10) # [GCC 5.4.0 20160609] # Embedded file title: /srv/my_package/my_module.py function_body = "seems right here"
For the category, you’ll have to decompile every methodology in flip
>>> uncompyle6.foremost.uncompyle( 2.7, my_module.MyClass.my_method.im_func.func_code, sys.stdout ) # uncompyle6 model 2.9.10 # Python bytecode 2.7 # Decompiled from: Python 2.7.12 (default, Nov 19 2016, 06:48:10) # [GCC 5.4.0 20160609] # Embedded file title: /srv/my_package/my_module.py class_method_body = "seems right here"
I hope you guys like this submit. Keep tuned for the following one within the upcoming days.
