deploy code with different python version

[shoulewoba]

When i try to protect some python sdk with pyconcrete, i just cannot deploy protected python sdk on another pc because python version might be unmatched. But as for python sdk, it might be deployed on a lot of pc of which python version cannot be control, so, is there any way to solve this problem?

pyconcrete compile .py to .pyc and then encripte to .pye .pyc is version dependency, different python version has different .pyc format.

There are 2 solution

1. Don't compile .py to .pyc, just encrypt .py to .pye pros: simple, need update pyconcrte source cons: lower security, it's not safe
2. Build your package in all support python version, the user need to download different version by them self

i just modified the pyconcrete-admin.py: def _compile_pye_file(self, args, py_file): """ if there is no .pyc file, compile .pyc first then compile .pye """ import pyconcrete pyc_file = py_file # + 'c' pye_file = py_file + 'e' pyc_exists = exists(pyc_file)

if not pyc_exists or os.stat(py_file).st_mtime != os.stat(pyc_file).st_mtime:

        #py_compile.compile(py_file, cfile=pyc_file)
    if not exists(pye_file) or os.stat(py_file).st_mtime != os.stat(pye_file).st_mtime:
        pyconcrete.encrypt_file(pyc_file, pye_file)
        if args.verbose:
            print('* create %s' % pye_file)
    else:
        if args.verbose:
            print('* skip %s' % pye_file)

    # .pyc doesn't exists at beginning, remove it after .pye created
    if not pyc_exists or args.remove_pyc:
        os.remove(pyc_file)
    if args.remove_py:
        os.remove(py_file)

just to skip the ".py ->.pyc" part, but which doesn't really work, ValueError will be raised from init.py of pyconcrete.

Do i need to modify many parts of pyconcrete to support the first solution?

you need to modify src/pyconcrete/__init__.py load_module() don't need to do marshal.loads, exec the source code directly
