This looks like a documentation bug. Functions in module os are usually just
thin wrappers around the underlying OS functions, and POSIX states that doing
nothing is the correct thing to do here. (It is arguably a bug in early Unix
implementations that got
Esa Peuha added the comment:
Someone needs to compare _maybe_compile to the equivalent C code used by the
real interpreter.
Well, _maybe_compile() just calls the built-in function compile() internally,
so I'm not sure what sort of comparison you want...

Actually Lib/_osx_support.py directly imports only five modules: os, re and sys
at top level, and contextlib and tempfile in _read_output(). These last two
aren't really needed at all, and there's no point even trying to avoid
importing os and sys, so the only

The problem seems to be
/Users/pyi/Library/Python/3.4/lib/python/site-packages/setuptools-0.9.8-py3.4.egg
according to the error page. What is that file? The fact that the second run
of the test succeeds implies that it could be a temporary file which
Esa Peuha added the comment:
Apparently related to issue 19205 and issue 19209. Looks like _osx_support
imports re which imports copyreg.

Just by looking at the code, there still seems to be a problem: test_site.py
was changed in 0b6052f2a8ee to test that the collections module isn't imported,
but due to a bug it (re)tests the re module instead (re_mods needs to be
changed to collection_mods

So best guess is that Microsoft's allocators have gotten fatally fragmented,
but I don't know how to confirm/refute that.
Let's test this in pure C. Compile and run the attached uglyhack.c on win32; if
it reports something significantly less than 100%, it's
Esa Peuha added the comment:
so I don't know where the global name 'r' is not defined message came from.
It came from Python 2.7. There are two separate bugs here, one in 3.x and the
other in 2.7: the 3.x bug has to do with bytes/string separation, while the 2.7
bug is that result

The wanted patch seems to be very simple: change PendingDeprecationWarning to
DeprecationWarning on line 24 of Lib/formatter.py but only for Python 3.5 (i.e.
no need to do anything until 3.4 is released).
On a related note, should formatter be added to PEP 4
New submission from Esa Peuha:
Here are some additions to documentation of a few functions:
all, any: alternative definitions using functools.reduce
enumerate: alternative definition using zip and itertools.count
sum: equivalent definition using functools.reduce and operator.add
Esa Peuha added the comment:
How would you give a single definition of reduce() that helps people to
understand both 2-arg and 3-arg variants? The way it is implemented in C is
impossible to duplicate in pure Python; the best you could do is a hack that
works unless someone *tries* to break

New submission from Esa Peuha:
I noticed a couple of issues with the Enum documentation. First, there are some
markup bugs which should be fixed by the attached file. Second, I think If the
only change desired is no aliases allowed is very bad English and should be
reworded; I would go
