Renamed copy_reg to copyreg in the standard library, to avoid
spurious warnings and ease later merging to py3k branch. Public
documentation remains intact.
callable() from copy_reg.py, so the interpreter now starts up
without warnings when '-3' is given. More work like this needs to
be done in the rest of the stdlib.
The constructor() call only made sense when it registered the
constructor as safe for unpickling. We should probably remove the
module-global function, but need to worry about backwards
compatibility.
This changes the default __new__ to refuse arguments iff tp_init is the
default __init__ implementation -- thus making it a TypeError when you
try to pass arguments to a constructor if the class doesn't override at
least __init__ or __new__.
this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).
I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code. This risk doesn't exist for the
extension registry.
doesn't have the _HEAPTYPE flag set, e.g. for time.struct_time and
posix.stat_result.
This fixes the immediate symptoms of SF bug #496873 (cPickle /
time.struct_time loop), replacing the infinite loop with an exception.
- Fix for SF bug #482752: __getstate__ & __setstate__ ignored (by Anon.)
In fact, only __getstate__ isn't recognized. This fixes that.
- Separately, the test for base.__flags__ & _HEAPTYPE raised an
AttributeError exception when a classic class was amongst the
bases. Fixed this with a hasattr() bandaid (classic classes never
qualify as the "hard" base class anyway, which is what the code is
trying to find).
