[issue3119] pickle.py is limited by python's call stack

[Sean Reifschneider]

Sean Reifschneider <jafo at tummy.com> added the comment:

Ugh, I forgot to check the output of my test run before submitting the last reply.  With the patch applied, "make test" fails with:

test_pickle
Fatal Python error: Cannot recover from stack overflow.
Fatal Python error: Cannot recover from stack overflow.
make: *** [test] Aborted (core dumped)

This is on Python 3 trunk, with the pickle3.patch applied (which applied cleanly).

For the Misc/NEWS I propose (in the Library section):

- Issue #3119: pickle.py can now handle deeply-nested data-structures
  without reaching the Python call stack limit.  NOTE: the pickle save()
  method is now a generator, though sub-classes of Pickler shouldn't
  override save().
