Serhiy Storchaka bfe1824d08 Issue #18473: Fixed 2to3 and 3to2 compatible pickle mappings.
Fixed ambigious reverse mappings.  Added many new mappings.  Import mapping
is no longer applied to modules already mapped with full name mapping.

Added tests for compatible pickling and unpickling and for consistency of
_compat_pickle mappings.

Alexandre Vassalotti d05c9ff845 Issue #6784: Strings from Python 2 can now be unpickled as bytes objects.
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.

Alexandre Vassalotti b6a2f2a0d1 Make framing optional in pickle protocol 4.
This will allow us to control in the future whether to use framing or not.
For example, we may want to turn it off for tiny pickle where it doesn't
help.

The change also improves performance slightly:

2013-04-20 13:19:46 -07:00
Alexandre Vassalotti 7c5e094cbf Make C and Python implementations of pickle load STRING opcodes the same way.
The C version tried to remove trailing whitespace between the last quote and
the newline character. I am not sure why it had this because pickle never
generated such pickles---for this to happen repr(some_string) would need to
return trailing whitespace. It was maybe there to make it easier for people
to write pickles in text editors. Anyhow, the Python version doesn't do this
so there is no point keeping this around anymore.

Also, I've changed the exception raised when a bad pickle is encountered.
Again this unlikely to make much difference to anyone though it does make
testing slightly nicer for us.

Brett Cannon 31f5929c1e Issue #10990: Prevent tests from clobbering a set trace function.
Many tests simply didn't care if they unset a pre-existing trace function. This
made test coverage impossible. This patch fixes various tests to put back any
pre-existing trace function. It also introduces test.support.no_tracing as a
decorator which will temporarily unset the trace function for tests which
simply fail otherwise.

Thanks to Kristian Vlaardingerbroek for helping to find the cause of various
trace function unsets.

  Issue #4176: Pickle would crash the interpreter when a __reduce__ function
  does not return an iterator for the 4th and 5th items.
  (sequence-like and mapping-like state)

  A list is not an iterator...

  Will backport to 2.6 and 2.5.

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.

Christian Heimes a37d4c693a Removed PyInt_GetMax and sys.maxint
I replaced sys.maxint with sys.maxsize in Lib/*.py. Does anybody see a problem with the change on Win 64bit platforms? Win 64's long is just 32bit but the sys.maxsize is now 2**63-1 on every 64bit platform.
Also added docs for sys.maxsize.

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.

Guido van Rossum 34d1928766 SF patch# 1770008 by Christian Heimes (plus some extras).
Completely get rid of StringIO.py and cStringIO.c.

I had to fix a few tests and modules beyond what Christian did, and
invent a few conventions.  E.g. in elementtree, I chose to
write/return Unicode strings whe no encoding is given, but bytes when
an explicit encoding is given.  Also mimetools was made to always
assume binary files.
