[issue672115] Assignment to __bases__ of direct object subclasses

[Lars]

Lars  added the comment:

ok, i see what you mean, for me at this time the most important question
is whta does 

class object(object)
pass

do, why can i change baseclasses after i redeclare object this way, and
will it get me into trouble when i use this to let users dynamically
define classes and inheritence relationships?

cheers

[issue6149] WeakValueDictionary constructor ported to Python 3.0 incorrectly

[mike bayer]

New submission from mike bayer :

The constructor for WeakValueDictionary does not obey the contract
documented in its comments:

# We inherit the constructor without worrying about the input
# dictionary; since it uses our .update() method, we get the right
# checks 

yet it initializes with:

   self.data = d = {}
   d.update(*args, **kw)

i.e. the "update()" method of dict, so that a dict passed to the
constructor initializes non-weakrefed values in the dict which is
completely invalid state.

Contrast to that of 2.6, which properly uses the superclass:

UserDict.UserDict.__init__(self, *args, **kw)

A simple test which raises an exception on 3.0.1 is as follows:

import weakref

class Foo(object):
pass

mydict = dict((k, Foo()) for k in range(10))

w = weakref.WeakValueDictionary(mydict)

assert w[5]

[issue1943] improved allocation of PyUnicode objects

There were a number of patches to support sharing of data between 
unicode objects.  (By Larry Hastings?)  They were rejected because (a)  
they were complicated, and (b)  it was possible to provoke pathological 
memory retention.

Yes, it's the "lazy strings" patches by Larry Hastings (it was for str,
not unicode, though). Issues are #1590352 and #1569040 (and perhaps
others).

In any case, as I said, it is easy to switch back to the old
representation, so I don't think it is an argument to block this patch.

[issue6151] Make PyDescr_COMMON conform to standard C

[Alexandre Vassalotti]

New submission from Alexandre Vassalotti :

PyDescrObject make use of the some undefined behavior noted in PEP 3123
for PyObject in Python 2.x. Although fixing this requires breaking
backward-compatibility, this shouldn't be much a problem since
PyDescrObject is only used directly by Python itself.

[issue6137] Pickle migration: Should pickle map "copy_reg" to "copyreg"?

[Alexandre Vassalotti]

Alexandre Vassalotti  added the comment:

If I understood correctly, #3675 is about making pickle data generated
by Python 3 readable by Python 2. However, this issue is about
compatibility in the other direction—i.e., making Python 2 pickles
readable by Python 3, which is easier.

I have a patch that make Unpickler translates the old names to the new
ones at runtime. The only thing missing in the patch is the unit tests
since I am not sure this should be tested. I am thinking using the
approach Collin Winter used for his compatibility tests in #5665.
However, his approach requires bidirectional pickle compatibility
between Python 2 and 3, which we don't have.

[issue6152] Parellel regression testing

This experimental patch introduces a new option to run regression tests

[issue6151] Make PyDescr_COMMON conform to standard C

[Martin v . Löwis]

Martin v. Löwis  added the comment:

The patch looks fine in principle. I believe many of the macro
applications are unnecessary, because the type of the variables being
accessed is already PyDescrObject.

Not sure whether this can be applied to 3.1 still.

[issue6153] email parsing - Rare Failure

[Winston Ewert]

New submission from Winston Ewert :

I was using email.message_from_string which eventually feeds block of
8192 bytes into the actual e-mail parsing code. However, in my case one
the blocks split the \r\n at the end of a submessage. This caused the
code to identify it as two newlines and thus the submessage headers were
interpreted as being content.

For my purposes I've changed:
NLCRE_crack = re.compile('(\r\n|\r|\n)')
to
NLCRE_crack = re.compile('(\r\n)')

Which prevents the problem.

I suspect that is not a good fix but I do not know the standard well
enough to know what would be a good fix.
