bpo-37210: Fix pure Python pickle when _pickle is unavailable (GH-14016)
Allow pure Python implementation of pickle to work
even when the C _pickle module is unavailable.

Fix test_pickle when _pickle is missing: declare PyPicklerHookTests
outside "if has_c_implementation:" block.

bpo-31993: Do not create frames for large bytes and str objects (#5114)
when serialize into memory buffer with C pickle implementations.

This optimization already is performed when serialize into memory
with Python pickle implementations or into a file with both
implementations.

Initial patch by Merlijn van Deen.

I've added a few unrelated docstring fixes in the patch while I was at
it, which makes the documentation for pickle a bit more consistent.

Benjamin Peterson ee8712cda4 #2621 rename test.test_support to test.support 2008-05-20 21:35:26 +00:00
Guido van Rossum f416981691 - A new pickle protocol (protocol 3) is added with explicit support
for bytes.  This is the default protocol.  It intentionally cannot
  be unpickled by Python 2.x.

- When a pickle	written	by Python 2.x contains an (8-bit) str
  instance, this is now decoded to a (Unicode) str instance.  The
  encoding used to do this defaults to ASCII, but can be overridden
  via two new keyword arguments to the Unpickler class.  Previously
  this would create bytes instances, which is usually wrong: str
  instances are often used to pickle attribute names etc., and text is
  more common than binary data anyway.

Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.

Walter Dörwald 21d3a32b99 Combine the functionality of test_support.run_unittest()

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.

Tim Peters 080c88b912 cPickle.c, load_build(): Taught cPickle how to pick apart
the optional proto 2 slot state.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

pickletester.py, test_pickle.py:  Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

dictobject.c, PyDict_Next():  documented intended use.

Guido van Rossum 5d9113d8be Implement appropriate __getnewargs__ for all immutable subclassable builtin
types.  The special handling for these can now be removed from save_newobj().
Add some testing for this.

Also add support for setting the 'fast' flag on the Python Pickler class,
which suppresses use of the memo.

Tim Peters 47a6b13988 Temporary hacks to arrange that the pickle tests relying on protocol 2
only get run by test_pickle.py now (& not by test_cpickle.py).  This
should be undone when protocol 2 is implemented in cPickle too.
test_cpickle should pass again.
