*Release date: 2010-03-01*
Core and Builtins
-----------------
- Issue #7309: Fix unchecked attribute access when converting
UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
strings.
- Issue #7649: "u'%c' % char" now behaves like "u'%s' % char" and raises a
UnicodeDecodeError if 'char' is a byte string that can't be decoded using
the default encoding.
- Issue #5677: Explicitly forbid write operations on read-only file objects,
and read operations on write-only file objects. On Windows, the system C
library would return a bogus result; on Solaris, it was possible to crash
the interpreter. Patch by Stefan Krah.

- Issue #7819: Check sys.call_tracing() arguments types.
- Issue #7788: Fix an interpreter crash produced by deleting a list
slice with very large step value.

returning NULL. The macro now returns a statically allocated empty
string instead.
- Issue #7604: Deleting an unset slotted attribute did not raise an
AttributeError.
- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
used to drop the time part of the result.

fixes the problem of some exceptions being thrown at shutdown when the
interpreter is killed. Patch by Adam Olsen.
- Issue #7084: Fix a (very unlikely) crash when printing a list from one
thread, and mutating it from another one. Patch by Scott Dial.
- Issue #1747858: Fix lchown & fchown to work with large uid's and gid's on
64-bit platforms.
Library
-------
- Issue #7250: Fix info leak of os.environ across multi-run uses of

Also, raise ValueError rather than TypeError when an unknown TIPC address
type is specified. Patch by Brian Curtin.
- Issue #6939: Fix file I/O objects in the `io` module to keep the original
file position when calling `truncate()`. It would previously change the
file position to the given argument, which goes against the tradition of
ftruncate() and other truncation APIs. Patch by Pascal Chambon.
- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when
the release file is empty.
- Issue #7748: Since unicode values are supported for some metadata options
in Distutils, the DistributionMetadata get_* methods will now return an utf-8
encoded string for them. This ensure that the upload and register commands
send the right values to PyPI without any error.
- Issue #1670765: Prevent email.generator.Generator from re-wrapping
headers in multipart/signed MIME parts, which fixes one of the sources of

by Arfrever.
- Issue #7071: byte-compilation in Distue.

no alternative to cPickle if you care about performance. Patch by Florent
Xicluna.
- Issue #745tch by
Victor Stinner.
- Issue #6511: ZipFile now raises BadZipfile (instead of an IOError) when
opening an empty or very small file.
- Issue #7552: Removed line feed in the base64 Authorization header in
the Distutils upload command to avoid an ers on long passwords. Initial patch by JP St. Pierre.

a connection with another process, rather than looping endlessly. The
default timeout is 20 seconds, which should be amply sufficient for
local connections.
- Issue #7282: Fix a memory leak when an RLock was used in a thread other
than those started through `threading.Thread` (for example, using
`thread.start_new_thread()`.
- Issue #7264: Fix a possible deadlock when deallocating thread-local objects
which are part of a reference cycle.
- Issue #7249: Methods of io.BytesIO now allow `long` as well as `int`
arguments.
- Issue #6665: Fix fnmatch to properly match filenames with newlines in them.
- Issue #1008086: Fixed socket.inet_aton() to always return 4 bytes even on
LP64 platforms (most 64-bit Linux, bsd, unix systems).
- Issue #7246 & Issue #7208: getpass now properly flushes input before
reading from stdin so that existing input does not confuse it and
lead to incorrect entry or an IOError. It also properly flushes it
afterwards to avoid the terminal echoing the input afterwards on
OSes such as Solaris.
- Issue #7244: itertools.izip_longest() no longer ignores exceptions
raised during the formation of an output tuple.

than the current precision) in shift and rotate.
- Issue #7082: When falling back to the MIME 'name' parameter, the
correct place to look for it is the Content-Type header.
- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
larger than emax.
- Issue #7205: Fix a possible deadlock when using a BZ2File object from
several threads at once.

is too large to fit in the current precision.
- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters
- Issue #5037: Proxy the __unicode__ special method to __unicode__ instead of
__str__.
- Issue #7481: When a threading.Thread failed to start it would leave the
instance stuck in initial state and present in threading.enumerate().

os.waitpid and os.read system calls where appropriate.
Extension Modules

on OSX.
- Expat: Fix DoS via XML document with malformed UTF-8 sequences
(CVE_2009_3560).
- Issue #7242: On Solaris 9 and earlier calling os.fork() from within a
thread could raise an incorrect RuntimeError about not holding the import
lock. The import lock is now reinitialized after fork.
- Issue #7999: os.setreuid() and os.setregid() would refuse to accept a -1
parameter on some platforms such as OS X.
Build
-----
- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.
- Issue #7661: Allow ctypes to be built from a non-ASCII directory path.

PYTHONDONTWRITEBYTECODE, PYTHONNOUSERSITE).
Tests
-----
- issue #7728: test_timeout was changed to use test_support.bind_port
instead of a hard coded port.
- Issue #7498: test_multiprocessing now uses test_support.find_unused_port
instead of a hardcoded port number in test_rapid_restart.
- Issue #7431: use TESTFN in test_linecache instead of trying to create a
file in the Lib/test directory, which might be read-only for the
user running the tests.
- Issue #7324: add a sanity check to regrtest argument parsing to
catch the case of an option with no handler.
- Issue #7295: Do not use a hardcoded file name in test_tarfile.
- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
primitives such as Lock, RLock, Condition, Event and Semaphore.

__all__ attribute, rather than using a hardcoded and incomplete list.
on the "pkgsrc-users" mailing list:
1.) Fix 64-Bit ABI check for Snow Leopard so it doesn't break the build
on older version of Mac OS X.
2.) Properly disable the "pyexpat" module and remove it from the
package list.

support.EnvironmentVarGuard objects restored the environment variables
incorrectly on __exit__.
* not "_sqlite", but "_sqlite3", fixes PR#42070.
* "bsddb" does not exists. (I can find it in Python21, not in Python23)
* "cjkcodecs" should not be disabled.
It is expected to exists in all Python variants and py-cjkcodecs was removed.
Although, the module name is "_multibytecodec" and "_codecs_*".
and missing "," after it kill subsecuent "gdbm".
* "mpz" was removed in Python24.
earlier, but there became no-ops due to my change to db4/bl3 and thus
didn't do harm. Now that part of that change was backed out they became
harmful again and thus need to go.
on Linux one can't build some extensions against an old Python (with
spurious -ldb4 linkage) anymore
also sync the bl3 files of the non-default versions with python25
for consistency
Compiles, installs, and runs on NetBSD-5.99.10/amd64; no further
tests done. Please test and fix on your platform!
What's new in Python-2.6:
The major theme of Python 2.6 is preparing the migration path to
Python 3.0, a major redesign of the language. Whenever possible,
Python 2.6 incorporates new features and syntax from 3.0 while
remaining compatible with existing code by not removing older
features or syntax. When it tries to do what it can, adding
compatibility functions in a future_builtins module and a -3 switch
to warn about usages that will become unsupported in 3.0.
Some significant new packages have been added to the standard
library, such as the multiprocessing and json modules, but there
