unlike earlier proposals, it doesn't break py_compile:
MAGIC = imp.get_magic()
fc = open(cfile, 'wb')
fc.write('\0\0\0\0')
wr_long(fc, timestamp)
marshal.dump(codeobject, fc)
fc.flush()
fc.seek(0, 0)
fc.write(MAGIC)
fc.close()
and it doesn't break imputil:
f = open(file, 'rb')
if f.read(4) == imp.get_magic():
t = struct.unpack('<I', f.read(4))[0]
if t == t_py:
code = marshal.load(f)
and it doesn't break any user code that does similar things
(squeeze, pythonworks, and a dozen other tools I've written;
applications using local copies of imputils, etc)
Cheers /F
