What's New in Python 2.6.6 rc 1?
================================
*Release date: 2010-08-03*
Core and Builtins
-----------------
- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
utf-16 incremental encoders.
- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
start byte and the continuation byte(s) are now considered invalid, instead
of the number of bytes specified by the start byte.
E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
Previous versions returned a single u'\ufffd'.
- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
the interpreter with characters outside the Basic Multilingual Plane
(higher than 0x10000).
- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
__hash__ in 3.x" warning. Also fix "XXX undetected error" that
arises from the "Overriding __eq__ blocks inheritance ..." warning
when turned into an exception: in this case the exception simply
gets ignored.
- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
entries, consider the first one.
- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
- In the unicode/str.format(), raise a ValueError when indexes to arguments are
too large.
- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
and error handler, instead of writing to the C stderr file in utf-8
- Issue #7902: When using explicit relative import syntax, don't try
implicit relative import semantics.
- Issue #7079: Fix a possible crash when closing a file object while using
it from another thread. Patch by Daniel Stutzbach.
- Issue #1533: fix inconsistency in range function argument
processing: any non-float non-integer argument is now converted to
an integer (if possible) using its __int__ method. Previously, only
small arguments were treated this way; larger arguments (those whose
__int__ was outside the range of a C long) would produce a TypeError.
- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize
is passed to bytearray.
- Issue #8329: Don't return the same lists from select.select when no fds are
changed.
- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
- Issue #1583863: An unicode subclass can now override the __unicode__ method.
- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
- Issue #7544: Preallocate thread memory before creating the thread to avoid
a fatal error in low memory condition.
- Issue #7820: The parser tokenizer restores all bytes in the right if
the BOM check fails.
- Issue #7072: isspace(0xa0) is true on Mac OS X
C-API
-----
- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
embedders of the interpreter to set sys.argv without also modifying
sys.path. This helps fix `CVE-2008-5983
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

- Issue #8313: traceback.format_exception_only() encodes unicode message to
ASCII with backslashreplace error handler if str(value) failed
- Issue #8567: Fix precedence of signals in Decimal module: when a
Decimal operation raises multiple signals and more than one of those
signals is trapped, the specification determines the order in which
the signals should be handled. In many cases this order wasn't
being followed, leading to the wrong Python exception being raised.

indefinitely if the other end didn't respond.
- The do_handshake() method of SSL objects now adjusts the blocking mode of
the SSL structure if necessary (as other methods already do).

underlying socket from being closed until all objects get truely destroyed.
- Issue #7943: Fix circular reference created when instantiating an SSL
socket. Initial patch by Péter Szabó.

Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
reads and writes are always retried by OpenSSL itself.
- Issue #6544: fix a reference leak in the kqueue implementation's error
handling.

- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
compared to other unix systems. In particular, os.getgroups() does
not reflect any changes made using os.setgroups() but basicly always
returns the same information as the id command.
os.getgroups() can now return more than 16 groups on MacOSX.
- Issue #9277: Fix bug in struct.pack for bools in standard mode
(e.g., struct.pack('>?')): if conversion to bool raised an exception
then that exception wasn't properly propagated on machines where
char is unsigned.
- Issue #7384: If the system readline library is linked against
ncurses, do not link the readline module against ncursesw. The
additional restriction of linking the readline and curses modules
against the same curses library is currently not enabled.
- Issue #2810: Fix cases where the Windows registry API returns

when building a shared library.
Tests
-----
- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
effectively raised. A new private utility ``_check_py3k_warnings`` has been
backported to help silencing py3k warnings.
- Issue #8672: Add a zlib test ensuring that an incomplete stream can be
handled by a decompressor object without errors (it returns incomplete
uncompressed data).

results with OpenSSL 1.0.0 and higher.
- Issue #8576: Remove use of find_unused_port() in test_smtplib and
test_multiprocessing. Patch by Paul Moore.
- Issue #7027: regrtest.py keeps a reference to the encodings.ascii module as a
workaround to #7140 bug
- Issue #3864: Skip three test_signal tests on freebsd6 because they fail
if any thread was previously started, most likely due to a platform bug.

type is specified. Patch by Brian Curtin.
- Issue #6939: Fix file I/O objects in the `io` module to keep the original

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

default timeout is 20 seconds, which should be amply sufficient for
local connections.

than those started through `threading.Thread` (for example, using
`thread.start_new_thread()`.

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.

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.
Bump package revision because of these changes.

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
aren way.
Python 2.6 also sees a number of improvements and bugfixes throughout
the source. A search through the change logs finds there were 259
patches applied and 612 bugs fixed between Python 2.5 and 2.6. Both
figures are likely to be underestimates.
