pyarmor.helper.merge #573

Closed populc closed 2 years ago

populc commented 3 years ago

I'm trying to obfuscate code for different platforms and versions of python with PyArmor Trial Version 6.8.0. To do this, with the help of the documentation, I have created a bat with the following commands:

pyarmor obfuscate --platform windows.x86.0  --platform windows.x86_64.0 --platform linux.x86.0  --platform linux.x86_64.0  --platform darwin.x86_64.0  --platform linux.arm.0 --platform linux.armv6.0  --platform linux.armv7.0  --platform linux.aarch32.0  --platform linux.aarch64.0 --platform android.aarch64.0  --platform android.armv7.0  --platform android.x86.0  --platform android.x86_64.0 --no-cross-protection -O py27 default_org.py
pyarmor3 obfuscate --platform windows.x86.0  --platform windows.x86_64.0 --platform linux.x86.0  --platform linux.x86_64.0  --platform darwin.x86_64.0  --platform linux.arm.0 --platform linux.armv6.0  --platform linux.armv7.0  --platform linux.aarch32.0  --platform linux.aarch64.0 --platform android.aarch64.0  --platform android.armv7.0  --platform android.x86.0  --platform android.x86_64.0 --no-cross-protection -O py38 default_org.py

python -m pyarmor.helper.merge py27/ py38/

where default.py is a python 2.7 and 3.8 compatible test script, and pyarmor3 is another bat as explained at https://pyarmor.readthedocs.io/en/latest/advanced.html#obfuscating-scripts-by-other-python-version.

The result of running the code in python 3.8 is correct, but if I try it in python 2.7 I get "RuntimeError: Marshal loads failed"

If in the last line of the bat we change the order of the arguments: python -m pyarmor.helper.merge py38/ py27/ the test result is also reversed: Python2.7 ok and python3.8 "RuntimeError: Marshal loads failed"

This is the expected performance? Can't do what I want?

Make sure the runtime files are latests, and the trial version doesn't support this feature.

  1. First make sure both py38/, py37 works
  2. Check the output log, make sure 2 versions are merged
  3. Run merged scripts in merged_dist/

  1. Effectively the content of each folder works in its own version of python

  2. K:\plugin.video.test>python -m pyarmor.helper.merge py27/ py38/

  3. We repeat result: The result of running the code in python 3.8 is correct, but if I try it in python 2.7 I get "RuntimeError: Marshal loads failed"

Make sure the runtime files are latests, and the trial version doesn't support this feature.

Effectively...

But does this mean that with the trial version it is not possible to have an obfuscated script valid for various platforms and versions of python?

Yes, refer to https://pyarmor.readthedocs.io/en/latest/change-logs.html#id7
