Guido van Rossum 4fb5b28dfc Three independent changes:
- Don't use "from copy_reg import *".

- Use cls.__module__ instead of calling whichobject(cls, cls.__name__);
  also try __module__ in whichmodule(), just in case.

- After calling save_reduce(), add the object to the memo.

Guido van Rossum d6ead328b3 *Semantic change*: when unpickling the instance variables of an
instance, use inst.__dict__.update(value) instead of a for loop with
setattr() over the value.keys().  This is more consistent (the
pickling doesn't use getattr() either but pickles inst.__dict__) and
avoids problems with instances that have a __setattr__ hook.

But it *is* a semantic change (because the setattr hook is no longer
used).  So beware!

Guido van Rossum 5ed5c4c364 Add the same _keep_alive patch (by Michael Scharff) that was added to
copy.deepcopy() a while ago.  Can't reproduce this but it doesn't
break anything and it looks like the code could have the same problem.

Guido van Rossum 8be9a11617 Restore two features of the original 1.4 pickle:
- which_module() search __main__ last;

- load_inst() no longer checks that the classname really refers to a class.

Guido van Rossum 5a56649e09 Remove Digital Creations copyright (Jim sez it's okay). 1997-04-11 22:31:56 +00:00
Guido van Rossum b72cf2d697 New version by Digital Creations, supports binary format compatible
with cPickle.

Guido van Rossum efd3a3a843 Implement find_class() without exec statement. 1997-03-14 04:21:10 +00:00
Guido van Rossum 36fc11e894 Compromise on test in find_class(): a user-defined function is okay,
but a built-in function is not.

Guido van Rossum abfd8064d8 This is the third time I check in this change :-(
Don't use assignments into inst.__dict__ to restore instance
variables; use setattr() instead.

Guido van Rossum 37a6f16d2e Slight update of doc string -- suggest default args for __init__, no
longer complain that __getinitargs__ is an ugly name.

Guido van Rossum c7c5e697c3 Optimizations and one intentional loophole by Jim Fulton.
The optimizations consist mostly of using local variables to cache
methods or instance variables used a lot (e.g. "self.write").

The loopholes allows marshalling extension types as long as they have
a __class__ attribute (in which case they may support the rest of the
class piclking protocol as well).  This allows pickling MESS extension
types.

Guido van Rossum 955c5d156d Set the base for atoi() and atol() to 0, since we're reading Python
numbers here, and so that atol() doesn't barf on the trailing 'L'.
Add a test case involving a long integer.

Guido van Rossum 7853647dd1 Don't atoi() the memo key.
Use atoi(), atol(), atof() instead of load_atomic for seed-up.

Guido van Rossum a48061a580 shelve.py: database of persistent objects, on top of pickle.py and anydbm.py
pickle.py: new low-level persistency module (used to be called flatten)
dbmac.py: stupid dbm clone for the Mac
anydbm.py: generic dbm interface (should be extended to support gdbm)
