PEP 352 implementation. Creates a new base class, BaseException, which has an

added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt

- Added context managers to:
- file

- threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
- decimal.Context
- Added contextlib.py, which defines @contextmanager, nested(), closing().

SF patch #1438387 , PEP 328: relative and absolute imports.
...
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.

In a Windows debug build, trying to open a file using

inside MS's C runtime code. We probably need to worm
around that in many places. I'm worming around it here
to stop the new test_with.py from assert-dying in the
Windows debug build (it calls compile() with an empty
string for "the file name", which indirectly leads to
C-level code in Python trying to fopen("", "r")).

PEP 308 implementation, including minor refdocs and some testcases. It

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

Add const to several API functions that take char *.
...
In C++, it's an error to pass a string literal to a char* function
without a const_cast(). Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.
I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc. Predictably, there were a large set of functions that
needed to be fixed as a result of these changes. The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].
One cast was required as a result of the changes: A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Patch #1197318 : Cygwin case-sensitive import patch
...
A problem regarding importing symlinked modules was recently reported on the
Cygwin mailing list:
http://cygwin.com/ml/cygwin/2005-04/msg00257.html
The following test case demonstrates the problem:
$ ls -l
total 1
lrwxrwxrwx 1 jt None 6 Apr 23 13:32 bar.py -> foo.py
-rw-r--r-- 1 jt None 24 Apr 18 20:13 foo.py
$ python -c 'import bar'
Traceback (most recent call last):
File "<string>", line 1, in ?
ImportError: No module named bar
Since Cygwin's case_ok() uses a modified version of the Windows's version, the
symlinked bar module actually resolves to file foo.py instead of bar.py. This
obviously causes the matching code to fail (regardless of case).
The patch fixes this problem by making Cygwin use the Mac OS X case_ok()
instead of a modified Window's version.

Add a test in case the underlying assumptions ever change (i.e. the

Fix bug that allowed future statements virtually anywhere in a module.

If we exit via the break here, we need to set ff_last_lineno or
FUTURE_POSSIBLE() will remain true. The bug affected statements
containing a variety of expressions, but not all expressions. It has
been present since Python 2.2.

Re-running python with/without the -Qnew flag uses incorrectly optimized

Improve signal handling, especially when using threads, by forcing an early

SF bug 1061968: threads: segfault or Py_FatalError at exit
...
PyGILState_Ensure(): The fix in 2.4a3 for bug 1010677 reintroduced thread
shutdown race bug 225673. Repaired by (once again) ensuring the GIL is
held whenever deleting a thread state.
Alas, there's no useful test case for this shy bug. Four years ago, only
Guido could provoke it, on his box, and today only Armin can provoke it
on his box. I've never been able to provoke it (but not for lack of
trying!).
This is a critical fix for 2.3.5 too, since the fix for 1010677 got
backported there already and so also reintroduced 225673. I don't intend to
backport this fix. For whoever (if anyone) does, there are other thread
fixes in 2.4 that need backporting too, and I bet they need to happen first
for this patch to apply cleanly.

There is no test for this change, because there is no way to provoke memory errors on demand. Test suite passes, though.
