PyS60 application packer: Pack as bytecode?

[mdop]

Could you please explain me what does the "Package As: Bytecode / Source code" feature in PyS60 application packer do?

From http://developer.symbian.org/wiki/in...hon_on_Symbian)

Package As (Byte or Source code)

Whether or not your scripts are converted to byte code before packaging. Byte code will run somewhat faster and additionally provide some anti-piracy protection for your script.

Default value: Scripts are converted to byte code.

I tought it converts py to pyc but after running dumpsis, the code is still not converted (default.py).

dumpsis does not convert the code to bytecode. For byte code conversion lookup for py_compile or compileall (for Python for PC).

We have it explained here.

I know what dumpsis is for - unpacking installation sis files.
I know how to compile python code to byte code.

But I don't understand what is the setting Bytecode/source code in application packer for if it doesn't work / doesn't compile py files for you...

Oh, it should have worked. But I tested and it doesn't work.

But hopefully they have fixed this in PyS60 2.0 Application packager.

You may still want to add it as a confirmed bug!

It compiles to bytecode every .py file you have in your project BUT default.py. So if you want to hide your code, you can write it in a separate .py file, and just use default.py as a wrapper.

When I tried to use this feature I did not worked for me. So I compiled each file by myself. That time I was not worried about hiding the code but I was looking for more performance. As the performance improvement was not a big deal, I gave up and decided to use original .py files.

However, in my opinion, python bytecodes are not safe enough. For instance, search for decompyle. I tested it some months ago when it had a free decompiler for small codes. The result is astonish.
