Re: [Jython-dev] co_names

[Samuele P. <pe...@in...>]

Hi.

If what you need is just co_names (although I don't get why and
how is that used/necessary) you should start looking at 
org.python.compiler.CodeCompiler,...
and the functions to construct code in org.python.core.Py

It's just boring, and you should roughly get how the compiler works
but it is not difficult.

To be honest jython does support co_names because it is not necessary,
in CPython co_names contains complementary info needed by the bytecode.

Even inspect.py does not use it. In any case if the use of co_names is
related to security adding it to jython is not that useful, because
potentially forged java bytecode could be delivered together with an
irrelevant co_names.

regards.
