Created attachment 366152 [details] Add bytecode values for Python 3.0 and 3.1 Description of problem: Attached is a patch that adds support for Python 3.0 and Python 3.1 bytecode files to the .pyc/.pyo support. With this file: $ file /usr/lib/python3.1/re.pyo /usr/lib/python3.1/re.pyo: python 3.1 byte-compiled Caveat: only tested with 3.1; I calculated up the value for 3.0 from the source in python's py3k branch's Python/import.c: [snip] Python 3.0a5: 3130 (lexical exception stacking, including POP_EXCEPT) [snip] Python 3.1a0: 3150 (optimize conditional branches: introduce POP_JUMP_IF_FALSE and POP_JUMP_IF_TRUE) [snip] Note that the value has 1 added to it in py3k's _PyImport_Init, giving: python 3.0: magic=3131 = 0x0c3b (hex) = 0x3b 0x0c 0xc0 0xd0a (header) and python 3.1: magic=3151 = 0x0c4f (hex) = 0x4f 0x0c 0x0d 0x0a (header)
