When I start PyCharm for remote python interpreter, it always performs "Uploading PyCharm helpers", even when the remote machine IP is the same and already containing previously uploaded helpers. Is the behaviour correct?

This is a well known problem that can be a major obstacle in productivity especially if you use disposable instances in your workflow. It leads to a forced coffee break of 20 minutes every time you want to connect to a remote system. Unacceptable.

Seems like PyCharm creates a build.txt file in the remote helper folder that just has the current PyCharm build number as its contents, for instance:

PY-171.4694.38

So it's possible to upload the helpers manually by using rsync on /Applications/PyCharm.app/Contents/helpers/ and finally manually creating a build.txt file with your current build number. After that, PyCharm should not attempt to re-upload them.

Example:

 $ rsync -avz /Applications/PyCharm.app/Contents/helpers/ cluster:/home/xapple/.pycharm_helpers/
 $ echo "PY-171.4694.38" > /home/xapple/.pycharm_helpers/build.txt
 $ python /home/xapple/.pycharm_helpers/pydev/setup_cython.py build_ext --inplace
