Using _unswizzled_password

[j0yu]

Issue

Python 3.2 removed Python 2's string.maketrans and translate methods, which were used by tank_cmd.py

Therefore when run with newer Python 3 interpreters, e.g. 3.7.6 from ShotGrid Desktop, calling shotgun_run_action_auth() will fail with

Traceback (most recent call last):
  File "/path/to/pipe-cfg/install/core/scripts/tank_cmd.py", line 1776, in <module>
    install_root, pipeline_config_root, is_localized, cmd_line[1:]
  File "/path/to/pipe-cfg/install/core/scripts/tank_cmd.py", line 643, in shotgun_run_action_auth
    rot13 = string.maketrans(
AttributeError: module 'string' has no attribute 'maketrans'

---

Fixed

• Using new _unswizzled_password() for Python 2 and 3 compatible rot-13 translation.

Hi @j0yu , I'm curious how you've run into this. IIRC this code was called from the old browser plugin based Shotgun integrations, which we stopped supporting years ago.

Once reason why we deprecated it was because it was totally unsafe, as you can imagine.

I ran into this trying to replicate the tank call I thought the "Clone this Configuration..." button would run, which resulted in

tank shotgun_run_action_auth __clone_pc "uid:name:linuxPath:macPath:winPath" "primaryCfgID" "userLogin" -

Is there a more modern CLI or API call that I can make to achieve what "Clone this Configuration..." button does?

There's not, no, but I'm surprised you ran into this code. Did you get a prompt asking you for your password when you ran this? Which platform are you running this on? Browser? Are you using the Shotgun Desktop for the browser integration or a super old browser with the java/browser plugin?

I'm currently running this on CentOS 7, Google Chrome 91.
It does prompt when my session token has expired, as per tank_cmd.py:shotgun_run_action_auth() when using - as password (final argument in CLI).

In practice, I'm just running the tank shotgun_run_action_auth ... from a shell, or Python subprocess.Popen, completely bypassing the web browser as I'm able to setup the colon-separated field values myself.

There's not, no, but I'm surprised you ran into this code.

So far as I have looked, this seems to be the most publicly available, dev-friendly way I could find to be able to perform the "Clone this Configuration..." action as described in Clone the Pipeline Configuration you want to add an app to and many of the other, official ShotGrid documentations.

Another option is to have tk-core/scripts and tk-core/python set in PYTHONPATH, then importing tank_cmd as a module:

import tank_cmd
tank_cmd.shotgun_run_action_auth(...)

But both running from shell using tank or through Python module raises errors if the Python interpreter that eventually runs the tank_cmd.py script is newer than, or is, Python 3.2
