[issue1022] use bytes for code objects

2007-09-02 Thread Brett Cannon 

Brett Cannon added the comment:

I have security/stability issues with code objects having mutable
bytecode.  This would allow someone to possibly crash the interpreter
with crappy bytecode.  I also have a worry that someone might come up
with some clever way of causing different code to execute through
manipulating what LOAD_GLOBALS or STORE_GLOBALS accesses/sets.

[issue1022] use bytes for code objects

2007-08-25 Thread Neal Norwitz 

New submission from Neal Norwitz:

This patch has a hack to read in marshaled code objects.  Bytes can't be 
marshaled currently (they are stored as strings).  So when reading a 
marshaled code object, the hack converts them to bytes.

All tests except test_modulefinder pass.

The issue is that since bytes are mutable, they aren't suitable for code 
objects since a user could change them at any time.
