I'm trying to pickle an instance of a class. It mostly works just fine
-- I can save the pickle to a file, restore it from that file, and
it's mostly okay. The problem is, some lists seem to disappear. For
example (snipped and crunched from the code giving me trouble):
---
class InitGame:
value = False
journal = []
game.InitGame()
def Save():
global game
import cPickle, gzip, os
# Change some data
game.journal.append("A value")
game.value = True
pickles = {'game': game}
jar = gzip.open("pickefile", 'wb')
cPickle.dump(pickles, jar, 2)
jar.close()
def Load():
global game
import gzip, os, cPickle
jar = gzip.open("picklefile", 'r')
loaded = cPickle.load(jar)
jar.close()
game = loaded["game"]
---
Now, if I save a pickle, then load it back in, I'll get an instance of
InitGame called "game", and game.value will be true, but the list
"journal" will be empty.
Am I missing something obvious about the pickle spec? Am I doing
something wrong? Or should I be hunting for a deeper bug in the code?
I've noticed that pretty much anything that's a list isn't saving to
the pickle (or loading from the pickle... it's hard to tell which).
