only once. Before, the type function was called twice in the case where the

be opened, even if a file argument was specified on the command line.

Extension Modules

-----------------

|
|
system call returning EINTR from within these methods.

|
|
- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
|
|
In particular, fix extension module build failures when trying to use
|
|
32-bit-only installer Pythons on systems with Xcode 4 (currently
|
|
OS X 10.8, 10.7, and optionally 10.6).
|
|
* Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
|
|
* Since Xcode 4 removes ppc support, extension module builds now
|
|
check for ppc compiler support and by default remove ppc and
|
|
ppc64 archs when they are not available.
|
|
* Extension module builds now revert to using system installed
|
|
headers and libs (/usr and /System/Library) if the SDK used
|
|
to build the interpreter is not installed or has moved.
|
|
* Try to avoid building extension modules with deprecated
|
|
and problematic Apple llvm-gcc compiler. If original compiler
|
|
is not available, use clang instead by default.

Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #13020: Fix a reference leak when allocating a structsequence object
|
|
fails. Patch by Suman Saha.
|
|
|
|
- Issue #13703: oCERT-2011-003: add -R command-line option and PYTHONHASHSEED
|
|
environment variable, to provide an opt-in way to protect against denial of
|
|
service attacks due to hash collisions within the dict and set types. Patch
|
|
by David Malcolm, based on work by Victor Stinner.
|
|
|
|
- Issue #11235: Fix OverflowError when trying to import a source file whose
|
|
modification time doesn't fit in a 32-bit timestamp.
|
|
|
|
- Issue #11638: Unicode strings in 'name' and 'version' no longer cause
|
|
UnicodeDecodeErrors.
|
|
|
|
- Fix the fix for issue #12149: it was incorrect, although it had the side
|
|
effect of appearing to resolve the issue. Thanks to Mark Shannon for
|
|
noticing.
|
|
|
|
- Issue #13546: Fixed an overflow issue that could crash the intepreter when
|
|
calling sys.setrecursionlimit((1<<31)-1).
|
|
|
|
- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
|
|
already accepts them).
|
|
|
|
- Issue #10519: Avoid unnecessary recursive function calls in
|
|
setobject.c.
|
|
|
|
- Issue #13268: Fix the assert statement when a tuple is passed as the message.
|
|
|
|
- Issue #13018: Fix reference leaks in error paths in dictobject.c.
|
|
Patch by Suman Saha.
|
|
|
|
- Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler
|
|
warnings. Patch by Josh Triplett and Petri Lehtinen.
|
|
|
|
- Issue #7833: Extension modules built using distutils on Windows will no
|
|
longer include a "manifest" to prevent them failing at import time in some
|
|
embedded situations.
|
|
|
|
- Issue #13186: Fix __delitem__ on old-style instances when invoked through
|
|
PySequence_DelItem.
|
|
|
|
- Issue #13156: Revert the patch for issue #10517 (reset TLS upon fork()),
|
|
which was only relevant for the native pthread TLS implementation.
|
|
|
|
- Issue #7732: Fix a crash on importing a module if a directory has the same
|
|
name than a Python module (e.g. "__init__.py"): don't close the file twice.
|
|
|
|
- Issue #12973: Fix overflow checks that invoked undefined behaviour in
|
|
int.__pow__. These overflow checks were causing int.__pow__ to produce
|
|
incorrect results with recent versions of Clang, as a result of the
|
|
compiler optimizing the check away. Also fix similar overflow checks
|
|
in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
|
|
bugs caused test failures with recent versions of Clang.
|
|
|
|

|
|
titlecased and cased non-letter characters.
|

|
|
- Issue #11627: Fix segfault when __new__ on a exception returns a
|
|
non-exception class.
|
|
|
|
- Issue #12149: Update the method cache after a type's dictionnary gets
|
|
cleared by the garbage collector. This fixes a segfault when an instance
|
|
and its type get caught in a reference cycle, and the instance's
|
|
deallocator calls one of the methods on the type (e.g. when subclassing
|
|
IOBase). Diagnosis and patch by Davide Rizzo.
|
|
|
|
- Issue #12501: Remove Py3k warning for callable. callable() is supported
|
|
again in Python 3.2.
|
|
|
|
- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
|
|
os.write() clamp the length to INT_MAX on Windows.
|
|
|
|
- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
|
|
the following case: sys.stdin.read() stopped with CTRL+d (end of file),
|
|
raw_input() interrupted by CTRL+c.
|
|
|
|
- Issue #10860: httplib now correctly handles an empty port after port
|
|
delimiter in URLs.
|
|
|
|
- dict_proxy objects now display their contents rather than just the class
|
|
name.

|
|
Patch by Suman Saha.
|
|
|
|
- Issue #13979: A bug in ctypes.util.find_library that caused
|
|
the wrong library name to be returned has been fixed.
|
|
|
|
- Issue #1326113: distutils' build_ext command --libraries option now
|
|
correctly parses multiple values separated by whitespace or commas.
|
|
|
|
- Issue #13993: HTMLParser is now able to handle broken end tags.

|
|
|
|
- Issue #9750: Fix sqlite3.Connection.iterdump on tables and fields
|
|
with a name that is a keyword or contains quotes. Patch by Marko
|
|
Kohtala.
|
|
|
|
- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
|
|
has left two versions of customize_compiler, the original in
|
|
distutils.sysconfig and another copy in distutils.ccompiler, with some
|
|
parts of distutils calling one and others using the other.
|
|
Complete the revert back to only having one in distutils.sysconfig as
|
|
is the case in 3.x.
|
|
|
|
- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
|
|
Distutils-based packages with C extension modules may fail because
|
|
Apple has removed gcc-4.2, the version used to build python.org
|
|
64-bit/32-bit Pythons. If the user does not explicitly override
|
|
the default C compiler by setting the CC environment variable,
|
|
Distutils will now attempt to compile extension modules with clang
|
|
if gcc-4.2 is required but not found. Also as a convenience, if
|
|
the user does explicitly set CC, substitute its value as the default
|
|
compiler in the Distutils LDSHARED configuration variable for OS X.
|
|
(Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
|
|
SDK, neither of which are available in Xcode 4. This change does not
|
|
attempt to override settings to support their use with Xcode 4.)
|
|
|
|
- Issue #9021: Add an introduction to the copy module documentation.
|
|
|
|
- Issue #6005: Examples in the socket library documentation use sendall, where
|
|
relevant, instead send method.

|
|
raise a ProgrammingError now.

metaclass is registered with copy_reg. Patch by Nicolas M. Thiéry and

- Issue #13058: ossaudiodev: fix a file descriptor leak on error. Patch by
|
|
Thomas Jarosch.

|
|
- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
|
|
check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
|
|
interpreter process. This could cause failures in non-Distutils subprocesses
|
|
and was unreliable since tests or user programs could modify the interpreter
|
|
environment after Distutils set it. Instead, have Distutils set the
|
|
deployment target only in the environment of each build subprocess. It is
|
|
still possible to globally override the default by setting
|
|
MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
|
|
greater or equal to the default value, the value with which the interpreter
|
|
was built.

- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
|
|
received. Now sendall() properly calls signal handlers if necessary,
|
|
and retries sending if these returned successfully, including on sockets
|
|
with a timeout.
|
|
|
|
- Issue #9947: logging: Fixed locking bug in stopListening.
|
|
|
|
- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
|
|
|
|
- Issue #9936: Fixed executable lines' search in the trace module.
|
|
|
|
- Issue #9928: Properly initialize the types exported by the bz2 module.
|
|
|
|
- Issue #9854: The default read() implementation in io.RawIOBase now
|
|
handles non-blocking readinto() returning None correctly.
|
|
|
|
- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
|
|
SSLSocket.sendto() to match the corresponding socket methods. Also,
|
|
fix various SSLSocket methods to raise socket.error rather than an
|
|
unhelpful TypeError when called on an unconnected socket. Original patch
|
|
by Andrew Bennetts.
|
|
|
|
- Issue #9826: OrderedDict.__repr__ can now handle self-referential
|
|
values: d['x'] = d.
|
|
|
|
- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
|
|
|
|
- Issue #9837: The read() method of ZipExtFile objects (as returned by
|
|
ZipFile.open()) could return more bytes than requested.
|
|
|
|
- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
|
|
This prevents user-created self-referencing ordered dictionaries from
|
|
becoming permanently uncollectable GC garbage. The downside is that
|
|
removing __del__ means that the internal doubly-linked list has to wait for
|
|
GC collection rather than freeing memory immediately when the refcnt drops
|
|
to zero.
|
|
|
|
- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
|
|
different internal state for small values of n. Fixed by salting the
|
|
value.
|
|
|
|
- Issue #9792: In case of connection failure, socket.create_connection()
|
|
would swallow the exception and raise a new one, making it impossible
|
|
to fetch the original errno, or to filter timeout errors. Now the
|
|
original error is re-raised.
|
|
|
|
- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
|
|
and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
|
|
be updated back after the system call. Original patch by Brian Brazil.
|
|
|
|
- Issue #1100562: Fix deep-copying of objects derived from the list and
|
|
dict types. Patch by Michele Orrù and Björn Lindqvist.
|
|
|
|
- Issue #7005: Fixed output of None values for RawConfigParser.write and
|
|
ConfigParser.write.
|
|
|
|
- Issue #808164: Fixed socket.close to avoid references to globals, to
|
|
avoid issues when socket.close is called from a __del__ method.
|
|
|
|
- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
|
|
can be set to False to turn off the previously undocumented 'popularity'
|
|
heuristic. Patch by Terry Reedy and Eli Bendersky
|
|
|
|
- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
|
|
falling into recursion.
|
|
|
|
- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
|
|
character years even if the message contains RFC822 two character years.
|
|
|
|
- Issue #8750: Fixed MutableSet's methods to correctly handle
|
|
reflexive operations, namely x -= x and x ^= x.
|
|
|
|
- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
|
|
error handling when accepting a new connection.
|
|
|
|

|
|
errors.

|
|
- Issue #9501: Fixed logging regressions in cleanup code.
|
|
|
|
- Issue #9214: Set operations on KeysView or ItemsView in the collections
|
|
module now correctly return a set. (Patch by Eli Bendersky.)
|
|
|
|
- Issue #9617: Signals received during a low-level write operation aren't
|
|
ignored by the buffered IO layer anymore.
|
|
|
|
- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
|
|
are not held onto after they are deleted elsewhere.
|
|
|
|
- Issue #9626: the view methods for collections.OrderedDict() were returning
|
|
the unordered versions inherited from dict. Those methods are now
|
|
overridden to provide ordered views.
|
|
|
|
- Issue #8688: MANIFEST files created by distutils now include a magic
|
|
comment indicating they are generated. Manually maintained MANIFESTs
|
|
without this marker will not be overwritten or removed.
|
|
|
|
- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
|
|
and a BadZipfile error is raised if it doesn't match (as used to be the
|
|
case in Python 2.5 and earlier).
|
|
|
|
- Issue #9550: a BufferedReader could issue an additional read when the
|
|
original read request had been satisfied, which could block indefinitely
|
|
when the underlying raw IO channel was e.g. a socket. Report and original
|
|
patch by Jason V. Miller.
|
|
|
|
- Issue #9551: Don't raise TypeError when setting the value to None for
|
|
SafeConfigParser instances constructed with allow_no_value == True.
|
|
|
|
- Issue #6915: Under Windows, os.listdir() didn't release the Global
|
|
Interpreter Lock around all system calls. Original patch by Ryan Kelly.
|
|
|
|
- Issue #3757: thread-local objects now support cyclic garbage collection.
|
|
Thread-local objects involved in reference cycles will be deallocated
|
|
timely by the cyclic GC, even if the underlying thread is still running.
|
|
|
|

|
|
- Issue #2944: asyncore doesn't handle connection refused correctly.

- 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 #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 #8748: Fix two issues with comparisons between complex and integer
|
|
objects. (1) The comparison could incorrectly return True in some cases
|
|
(2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
|
|
(2) The comparison raised an OverflowError for large integers, leading
|
|
to unpredictable exceptions when combining integers and complex objects
|
|
in sets or dicts.
|
|
|
|
- Issue #5211: Implicit coercion for the complex type is now completely
|
|
removed. (Coercion for arithmetic operations was already removed in 2.7
|
|
alpha 4, but coercion for rich comparisons was accidentally left in.)
|
|
|
|
- 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 #8868: Fix that ensures that python scripts have access to the
|
|
Window Server again in a framework build on MacOSX 10.5 or earlier.
|
|
|
|
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>`_.

|
*Release date: 2010-05-08*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``.
|
|
|
|
- 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 #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching
|
|
for the module file to be executed with the -m command line option.
|
|
|
|
- Issue #7319: When -Q is used, do not silence DeprecationWarning.
|
|
|
|
- Issue #7332: Remove the 16KB stack-based buffer in
|
|
``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
|
|
benefit compared to the dynamic memory allocation fallback. Patch by
|
|
Charles-François Natali.
|
|
|
|
- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
|
|
passed to bytearray.
|
|
|
|
- Issue #7072: ``isspace(0xa0)`` is true on Mac OS X.
|
|
|
|
- Issue #8404: Fix set operations on dictionary views.
|
|
|
|
- Issue #8084: PEP 370 now conforms to system conventions for framework builds
|
|
on MacOS X. That is, ``python setup.py install --user`` will install into
|
|
``~/Library/Python/2.7`` instead of ``~/.local``.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #8681: Make the zlib module's error messages more informative when the
|
|
zlib itself doesn't give any detailed explanation.
|
|
|
|
- Issue #8571: Fix an internal error when compressing or decompressing a chunk
|
|
larger than 1GB with the zlib module's compressor and decompressor objects.
|
|
|
|
- Issue #8573: asyncore ``_strerror()`` function might throw ValueError.
|
|
|
|
- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
|
|
messages when accessing undefined class attributes because of the cheap
|
|
inheritance with the underlying socket object. The cheap inheritance has been
|
|
deprecated.
|
|
|
|
- Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk
|
|
fills. Patch by Tres Seaver.
|
|
|
|
- Issue #7755: Use an unencumbered audio file for tests.
|
|
|
|
- Issue #8621: ``uuid.uuid4()`` returned the same sequence of values in the
|
|
parent and any children created using ``os.fork`` on Mac OS X 10.6.
|
|
|
|
- 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.
|
|
|
|
- Issue #7865: The close() method of :mod:`io` objects should not swallow
|
|
exceptions raised by the implicit flush(). Also ensure that calling close()
|
|
several times is supported. Patch by Pascal Chambon.
|
|
|
|
- Issue #8576: logging updated to remove usage of find_unused_port().
|
|
|
|
- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
|
|
gc.DEBUG_STATS.
|
|
|
|
- Issue #8354: The siginterrupt setting is now preserved for all signals, not
|
|
just SIGCHLD.
|
|
|
|
- Issue #7192: ``webbrowser.get("firefox")`` now works on Mac OS X, as does
|
|
``webbrowser.get("safari")``.
|
|
|
|
- Issue #8577: ``distutils.sysconfig.get_python_inc()`` now makes a difference
|
|
between the build dir and the source dir when looking for "python.h" or
|
|
"Include".
|
|
|
|
- Issue #8464: tarfile no longer creates files with execute permissions set when
|
|
mode="w|" is used.
|
|
|
|
- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions of
|
|
the Linux kernel. Patch by Yaniv Aknin.
|
|
|
|
- Issue #6312: Fix http HEAD request when the transfer encoding is chunked. It
|
|
should correctly return an empty response now.
|
|
|
|
- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
|
|
suites, the ``IGNORE_EXCEPTION_DETAIL`` directive now also ignores the module
|
|
location of the raised exception. Based on initial patch by Lennart Regebro.
|
|
|
|
- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline before
|
|
the certificate footer. Patch by Kyle VanderBeek.
|
|
|
|
- Issue #8546: Reject None given as the buffering argument to ``_pyio.open()``.

|
|
- Issue #6656: Fix locale.format_string to handle escaped percents and mappings.
|
|
|
|
- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
|
|
the method could block indefinitely if called just before the event loop
|
|
started running. This also fixes the occasional freezes witnessed in
|
|
test_httpservers.
|
|
|
|
- Issue #5103: SSL handshake would ignore the socket timeout and block
|
|
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).
|
|
|
|
- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
|
|
|
|
- Issue #5238: Calling makefile() on an SSL object would prevent the 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.
|
|
|
|
- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
|
|
string "python" as the *ident*. openlog() arguments are all optional and
|
|
keywords.
|
|
|
|
- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
|
|
non-infinite timeout. Also make that method friendlier with applications
|
|
wanting to continue using the socket in clear-text mode, by disabling
|
|
OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
|
|
|
|
- Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl
|
|
extension, such that verification of some SSL certificates doesn't fail
|
|
because of an "unknown algorithm".
|
|
|
|
- Issue #8437: Fix test_gdb failures, patch written by Dave Malcolm
|
|
|
|
- Issue #4814: The timeout parameter is now applied also for connections
|
|
resulting from PORT/EPRT commands.
|
|
|
|
- Issue #8463: Add missing reference to bztar in shutil's documentation.
|
|
|
|
- Issue #8438: Remove reference to the missing "surrogateescape" encoding error
|
|
handler from the new IO library.
|
|
|
|
- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response code
|
|
as stated in RFC-959 at chapter 5.4.
|
|
|
|
- Issue #8279: Fix test_gdb failures.
|
|
|
|
- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
|
|
available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
|
|
|
|
- Issue #2987: RFC 2732 support for urlparse (IPv6 addresses). Patch by Tony
|
|
Locke and Hans Ulrich Niedermann.
|
|
|
|
- Issue #7585: difflib context and unified diffs now place a tab between
|
|
filename and date, conforming to the 'standards' they were originally designed
|
|
to follow. This improves compatibility with patch tools.
|
|
|
|
- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
|
|
character sets will now consistently use a Content-Transfer-Encoding of 7bit
|
|
rather than sometimes being marked as 8bit.
|
|
|
|
- Issue #8330: Fix expected output in test_gdb.
|
|
|
|
- Issue #8374: Update the internal alias table in the :mod:`locale` module to
|
|
cover recent locale changes and additions.
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #8644: Improved accuracy of ``timedelta.total_seconds()``.
|
|
|
|
- Use Clang 2.7's static analyzer to find places to clean up some code.
|
|
|
|
- Build the ossaudio extension on GNU/kFreeBSD.
|
|
|
|
- On Windows, ctypes does no longer check the stack before and after calling a
|
|
foreign function. This allows to use the unmodified libffi library.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- 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).
|
|
|
|
- Issue #8490: asyncore now has a more solid test suite which actually tests its
|
|
API.
|
|

|
|

|
|
SSL shutdowns.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
|
|
(Optimization was unintentionally turned on in gcc --with-pydebug builds in
|
|
2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
|
|
strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)
|
|
|
|
- Issue #8509: Fix quoting in help strings and code snippets in configure.in.
|
|
|
|
- Issue #3646: It is now easily possible to install a Python framework into your
|
|
home directory on Mac OS X, see Mac/README for more information.

What's New in Python 2.7 beta 1?
|
|
================================
|
|
|
|
*Release date: 2010-04-10*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #7301: Add environment variable $PYTHONWARNINGS.
|
|
|
|
- Issue #8329: Don't return the same lists from select.select when no fds are
|
|
changed.
|
|
|
|
- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
|
|
on 64-bit machines. The shift count for either left or right shift is
|
|
permitted to be up to sys.maxsize.
|
|
|
|
- Ensure that tokenization of identifiers is not affected by locale.
|
|
|
|
- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
|
|
|
|
- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
|
|
|
|
- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
|
|
with a non-empty format string. This is an effort to future-proof user
|
|
code. If a derived class does not currently implement __format__ but later
|
|
adds its own __format__, it would most likely break user code that had
|
|
supplied a format string. This will be changed to a DeprecationWarning in
|
|
Python 3.3 and it will be an error in Python 3.4.
|
|
|
|
- Issue #8268: Old-style classes (not just instances) now support weak
|
|
references.
|
|
|
|
- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
|
|
is set.
|
|
|
|
- Issue #1583863: An unicode subclass can now override the __unicode__ method
|
|
|
|
- Issue #6474: Make error message from passing an inadequate number of keyword
|
|
arguments to a function correct.
|
|
|
|
- Issue #8164: Don't allow lambda functions to have a docstring.
|
|
|
|
- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
|
|
(SIGINT). If an error occurs while importing the site module, the error is
|
|
printed and Python exits. Initialize the GIL before importing the site
|
|
module.
|
|
|
|
- Code objects now support weak references.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
|
|
|
|
- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
|
|
using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
|
|
`ssl.OPENSSL_VERSION_NUMBER`.
|
|
|
|
- Issue #8310: Allow dis to examine new style classes.
|
|
|
|
- Issue #8257: The Decimal construct now accepts a float instance directly,
|
|
converting that float to a Decimal of equal value:
|
|
|
|
>>> Decimal(1.1)
|
|
Decimal('1.100000000000000088817841970012523233890533447265625')
|
|
|
|
- collections.Counter() now supports a subtract() method.
|
|
|
|
- The functools module now has a total_ordering() class decorator to simplify
|
|
the specification of rich comparisons.
|
|
|
|
- The functools module also adds cmp_to_key() as a tool to transition old-style
|
|
comparison functions to new-style key-functions.
|
|
|
|
- Issue #8294: The Fraction constructor now accepts Decimal and float instances
|
|
directly.
|
|
|
|
- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
|
|
InvalidOperation instead of returning False. (Comparisons involving a quiet
|
|
NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
|
|
signaling NaNs remain unhashable.
|
|
|
|
- Issue #2531: Comparison operations between floats and Decimal instances now
|
|
return a result based on the numeric values of the operands; previously they
|
|
returned an arbitrary result based on the relative ordering of id(float) and
|
|
id(Decimal).
|
|
|
|
- Issue #8233: When run as a script, py_compile.py optionally takes a single
|
|
argument `-` which tells it to read files to compile from stdin. Each line is
|
|
read on demand and the named file is compiled immediately. (Original patch by
|
|
Piotr Ożarowski).
|
|
|
|
- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
|
|
function like a normal call.
|
|
|
|
- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
|
|
form feed (0x0C) are now considered linebreaks, as specified in Unicode

|
|
|
|
- Comparisons using one of <, <=, >, >= between a complex instance and a
|
|
Fractions instance now raise TypeError instead of returning True/False. This
|
|
makes Fraction <=> complex comparisons consistent with int <=> complex, float
|
|
<=> complex, and complex <=> complex comparisons.

locale.
|
|
|
|
- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
|
|
to an non existent program name and Python is unable to retrieve the real
|
|
program name.
|
|
|
|
- Issue #8117: logging: Improved algorithm for computing initial rollover time
|
|

Extension Modules
|
|
-----------------
|
|
|
|
- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
|
|
|
|
- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
|
|
|
|
- Issue #8156: bsddb module updated to version 4.8.4.
|
|
http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4. This update drops
|
|
support for Berkeley DB 4.0, and adds support for 4.8.
|
|
|
|
- Issue #3928: os.mknod() now available in Solaris, also.
|
|
|
|
- Issue #8142: Update libffi to the 3.0.9 release.
|
|
|
|
- Issue #8300: When passing a non-integer argument to struct.pack with any
|
|
integer format code, struct.pack first attempts to convert the non-integer
|
|
using its __index__ method. If that method is non-existent or raises
|
|
TypeError it goes on to try the __int__ method, as described below.
|
|
|
|
- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
|
|
integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
|
|
argument's __int__ method to convert to an integer before packing. It also
|
|
produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
|
|
inconsistent: __int__ was used for some integer codes but not for others, and
|
|
the set of integer codes for which it was used differed between native packing
|
|
and standard packing.)
|
|
|
|
- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
|
|
the return value of QueryReflectionKey.
|
|
|
|
Tools/Demos
|
|
-----------
|
|
|

|
|
number of background CPU-bound Python threads.
|
|
|
|
- python-config now supports multiple options on the same command line.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #8032: For gdb7, a python-gdb.py file is added to the build, allowing to
|
|
use advanced gdb features when debugging Python.
|
|
|
|
- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable
|
|
anymore. It also forwards the LDFLAGS settings to the linker when building a
|
|
shared library.
|
|
|
|
- Issue #6716: Quote -x arguments of compileall in MSI installer.
|
|
|
|
- Issue #7705: Fix linking on FreeBSD.
|
|
|
|
- Make sure that the FreeBSD build of the included libffi uses the proper
|
|
assembly file.
|
|
|
|
C-API
|
|
-----
|
|
|
|
- Issue #8276: PyEval_CallObject() is now only available in macro form. The
|
|
function declaration, which was kept for backwards compatibility reasons, is
|
|
now removed (the macro was introduced in 1997!).
|
|
|
|
- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported from
|
|
Python 3.1. All existing Python CObjects in the main distribution have been
|
|
converted to capsules. To address backwards-compatibility concerns,
|
|
PyCObject_AsVoidPtr() was changed to understand capsules.
|
|
|
|
Tests
|

-----
|
|
|
|
- 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.
|
|
|
|

|
|
exception of canonical and is_canonical) now accept instances of int and long
|
|
wherever a Decimal instance is accepted, and implicitly convert that argument
|
|
to Decimal. Previously only some arguments were converted.

*Release date: 2010-02-06*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- 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 #7853: Normalize exceptions before they are passed to a context
|
|
manager's ``__exit__()`` method.

|
|
very large step value.
|
|
|
|
- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
|
|
and add the additional members returned in an OSVERSIONINFOEX structure. The
|
|
new members are service_pack_major, service_pack_minor, suite_mask, and
|
|
product_type.
|
|
|
|
- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
|
|
could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
|
|
returning NULL. The macro now returns a statically allocated empty string
|
|
instead.
|
|
|
|
- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
|
|
methods of bytes, bytearray and unicode objects by using a common
|
|
implementation based on stringlib's fast search. Patch by Florent Xicluna.
|
|
|
|
- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
|
|
including:
|
|
|
|
(1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
|
|
strings,
|
|
(2) a crash in dtoa.c that occurred in debug builds when parsing certain long
|
|
numeric strings corresponding to subnormal values,
|
|
(3) a memory leak for some values large enough to cause overflow, and
|
|
(4) a number of flaws that could lead to incorrectly rounded results.
|
|
|
|
- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
|
|
option is not used.
|
|
|
|
- Issue #2335: Backport set literals syntax from Python 3.x.
|

|
|
Library
|

-------
|
|
|
|
- Issue #9137: Fix issue in MutableMapping.update, which incorrectly
|
|
treated keyword arguments called 'self' or 'other' specially.
|
|
|
|
- Issue #7835: shelve should no longer produce mysterious warnings during
|
|
interpreter shutdown.
|
|
|
|
- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
|
|
XML processing instructions and comments. These raw characters are allowed
|
|
by the XML specification, and are necessary when outputting e.g. PHP code in
|
|
a processing instruction. Patch by Neil Muller.
|
|
|
|
- Issue #7869: logging: Improved diagnostic for format-time errors.
|
|
|
|

|
|
specified, rather than fall through to AF_PACKET (in the ``socket`` module).
|
|
Also, raise ValueError rather than TypeError when an unknown TIPC address
|
|
type is specified. Patch by Brian Curtin.
|
|
|
|
- logging: Implemented PEP 391.
|
|
|
|
- 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 #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
|
|
class used to represent files stored inside an archive. The new
|
|
implementation is significantly faster and can be wrapped in a
|
|
``io.BufferedReader`` object for more speedups. It also solves an issue
|
|
where interleaved calls to ``read()`` and ``readline()`` give wrong results.
|
|
Patch by Nir Aides.
|
|
|
|
- Issue #7792: Registering non-classes to ABCs raised an obscure error.

|
- 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 ensures that the upload and register commands
|
|
send the correct 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
|
|
invalid modifications to such parts by Generator.
|
|
|
|
- Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a
|
|
1-byte argument. Patch by Victor Stinner.
|
|
|
|
- Issue #3299: Fix possible crash in the _sre module when given bad argument
|
|
values in debug mode. Patch by Victor Stinner.
|
|
|
|
- Issue #7703: Add support for the new buffer API to functions of the binascii
|
|
module. Backported from py3k by Florent Xicluna, with some additional tests.
|
|
|
|
- Issue #2846: Add support for gzip.GzipFile reading zero-padded files. Patch
|
|
by Brian Curtin.
|
|
|
|
- Issue #5827: Make sure that normpath preserves unicode. Initial patch by
|
|
Matt Giuca.
|
|
|
|
- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
|
|
Extension extra options may change the output without changing the .c file).
|
|
Initial patch by Collin Winter.

What's New in Python 2.7 alpha 2?
|
|
=================================
|
|
|
|
*Release date: 2010-01-09*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- The ``__complex__()`` method is now looked up on the class of instances to
|
|
make it consistent with other special methods.
|
|
|
|
- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
|
|
`rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
|
|
|
|
- Issue #5080: A number of functions and methods previously produced a
|
|
DeprecationWarning when passed a float argument where an integer was expected.
|
|
These functions and methods now raise TypeError instead. The majority of the
|
|
effects of this change are in the extension modules, but some core functions
|
|
and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
|
|
and many unicode/str methods.
|
|
|
|
- Issue #7604: Deleting an unset slotted attribute did not raise an
|
|
AttributeError.
|
|
|
|
- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
|
|
in ** operator. The behaviour now conforms to that described in C99 Annex F.
|
|
|
|
- Issue #7579: The msvcrt module now has docstrings for all its functions.
|
|
|
|
- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
|
|
used to drop the time part of the result.
|
|
|
|
- Issue #1811: Improve accuracy and cross-platform consistency for true division
|
|
of integers: the result of a/b is now correctly rounded for ints a and b (at
|
|
least on IEEE 754 platforms), and in particular does not depend on the
|
|
internal representation of a long.
|
|
|
|
- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
|
|
same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
|
|
in the subclass.
|
|
|
|
- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
|
|
executables on OSX.
|
|
|
|
These executables now work properly with the arch(1) command: ``arch -ppc
|
|
python`` will start a universal binary version of python in PPC mode (unlike
|
|
previous releases).
|
|
|
|
- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
|
|
underlying error when the coercion fails for the left hand operand.
|
|
|
|
- Issue #7491: Metaclass's __cmp__ method was ignored.
|
|
|
|
- Issue #7466: Segmentation fault when the garbage collector is called in the
|
|
middle of populating a tuple. Patch by Florent Xicluna.
|
|
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
|
|
allowing for a maximum number of tasks within the pool to be completed by the
|
|
worker before that worker is terminated, and a new one created to replace it.
|
|
|
|
- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc
|
|
when it has a fully qualified configuration prefix. Initial patch by
|
|
Arfrever.
|
|
|
|
- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
|
|
renaming of `cPickle` to `pickle`. The warning was annoying since there's no
|
|
alternative to cPickle if you care about performance. Patch by Florent
|
|
Xicluna.
|
|
|
|
- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor
|
|
Stinner.
|
|
|
|
- Issue #7092: Fix the DeprecationWarnings emitted by the standard library when
|
|
using the -3 flag. Patch by Florent Xicluna.
|
|
|
|
- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
|
|
make it implement the ``io.BufferedIOBase`` ABC to allow for further speedups
|
|
by wrapping it in an ``io.BufferedReader``. Patch by Nir Aides.
|
|
|
|
- Issue #3972: ``httplib.HTTPConnection`` now accepts an optional source_address
|
|
parameter to allow specifying where your connections come from.
|
|
|
|
- ``socket.create_connection()`` now accepts an optional source_address
|
|
parameter.
|
|
|
|
- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
|
|
Initial patch by Brian Curtin.
|
|
|
|
- Distutils now correctly identifies the build architecture as "x86_64" when
|
|
building on OSX 10.6 without "-arch" flags.
|
|
|
|
- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest file in text
|
|
mode.
|
|
|
|
- Issue #7552: Removed line feed in the base64 Authorization header in the
|
|
Distutils upload command to avoid an error when PyPI reads it. This occurs on
|
|
long passwords. Initial patch by JP St. Pierre.
|
|
|
|
- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by
|
|
Tatsuhiro Tsujikawa.
|
|
|
|
- Issue #7349: Make methods of file objects in the io module accept None as an
|
|
argument where file-like objects (ie StringIO and BytesIO) accept them to mean
|
|
the same as passing no argument.
|
|
|
|
- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
|
|
argument like other file objects.
|
|
|
|
- Issue #7357: tarfile no longer suppresses fatal extraction errors by default.
|
|
|
|
- Issue #7470: logging: Fix bug in Unicode encoding fallback.
|
|
|
|
- Issue #5949: Fixed IMAP4_SSL hang when the IMAP server response is missing
|
|
proper end-of-line termination.
|
|
|
|
- Issue #7457: Added a read_pkg_file method to
|
|
``distutils.dist.DistributionMetadata``.
|
|
|
|
- Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and non
|
|
buffer API supporting objects as input. That behavior is for 3.x only.
|
|
|
|
C-API
|
|
-----
|
|
|
|
- Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous
|
|
to ``PyLong_AsLongAndOverflow()``.
|
|
|
|
- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
|
|
``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
|
|
``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
|
|
float arguments for integer format codes (other than 'L'): previously an
|
|
attempt to pass a float resulted in a DeprecationWarning; now it gives a
|
|
TypeError. For the 'L' format code (which previously had no warning) there is
|
|
now a DeprecationWarning.
|
|
|
|
- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built.
|
|
|
|
- Issue #6943: Use pkg-config to find the libffi headers when the
|
|
``--with-system-ffi`` flag is used.
|
|
|
|
- Issue #7609: Add a ``--with-system-expat`` option that causes the system's
|
|
expat library to be used for the pyexpat module instead of the one included
|
|
with Python.
|
|
|
|
- Issue #7589: Only build the nis module when the correct header files are
|
|
found.
|
|
|
|
- Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows.
|
|
|
|
- Issue #7541: when using ``python-config`` with a framework install the
|
|
compiler might use the wrong library.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- Issue #7376: Instead of running a self-test (which was failing) when called
|
|
with no arguments, doctest.py now gives a usage message.
|
|
|
|
- Issue #7396: Fix regrtest -s, which was broken by the -j enhancement.
|
|
|
|
- Issue #7498: test_multiprocessing now uses test_support.find_unused_port
|
|
instead of a hardcoded port number in test_rapid_restart.
|
|
|
|
|
|
What's New in Python 2.7 alpha 1
|
|
================================
|
|
|
|
*Release date: 2009-12-05*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
|
|
when called with invalid values.
|
|
|
|
- Issue #3382: 'F' formatting for float and complex now convert the result to
|
|
upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
|
|
to 'g' for large values.
|
|
|
|
- Remove switch from "%f" formatting to "%g" formatting for floats larger than
|
|
1e50 in absolute value.
|
|
|
|
- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
|
|
1e-100 used to raise OverflowError, but now gives the requested 120
|
|
significant digits instead.
|
|
|
|
- Add Py3k warnings for parameter names in parentheses.
|
|
|
|
- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
|
|
|
|
- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
|
|
10.6.
|
|
|
|
- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
|
|
decimal string that's guaranteed to round back to x under correct rounding
|
|
(with round-half-to-even rounding mode). Previously it gave a string based on
|
|
rounding x to 17 decimal digits. repr(x) for a complex number behaves
|
|
similarly. On platforms where the correctly-rounded strtod and dtoa code is
|
|
not supported (see below), repr is unchanged.
|
|
|
|
- Issue #7117: On almost all platforms: float-to-string and string-to-float
|
|
conversions within Python are now correctly rounded. Places these conversions
|
|
occur include: str for floats and complex numbers; the float and complex
|
|
constructors; old-style and new-style numeric formatting; serialization and
|
|
deserialization of floats and complex numbers using marshal, pickle and json;
|
|
parsing of float and imaginary literals in Python code; Decimal-to-float
|
|
conversion.
|
|
|
|
The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
|
|
providing correctly-rounded strtod and dtoa C functions. This code is
|
|
supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
|
|
the C compiler. There may be a small number of platforms on which correct
|
|
operation of this code cannot be guaranteed, so the code is not used: notably,
|
|
this applies to platforms where the C double format is not IEEE 754 binary64,
|
|
and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
|
|
and Python's configure script is unable to determine how to change the FPU
|
|
precision. On these platforms conversions use the platform strtod and dtoa,
|
|
as before.
|
|
|
|
- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
|
|
uses the correctly-rounded string <-> float conversions described above (when
|
|
available), and so produces correctly rounded results that will display nicely
|
|
under the float repr. There are two related small changes: (1) round now
|
|
accepts any class with an ``__index__()`` method for its second argument (but
|
|
no longer accepts floats for the second argument), and (2) an excessively
|
|
large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
|
|
raises an exception.
|
|
|
|
- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
|
|
|
|
- Fix several issues with ``compile()``. The input can now contain Windows and
|
|
Mac newlines and is no longer required to end in a newline.
|
|
|
|
- Remove length limitation when constructing a complex number from a unicode
|
|
string.
|
|
|
|
- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
|
|
during the formation of an output tuple.
|
|
|
|
- Issue #1087418: Boost performance of bitwise operations for longs.
|
|
|
|
- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
|
|
which fixes the problem of some exceptions being thrown at shutdown when the
|
|
interpreter is killed. Patch by Adam Olsen.
|
|
|
|
- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
|
|
and note that they are unsafe and deprecated.
|
|
|
|
- Issue #7120: logging: Remove import of multiprocessing which is causing crash
|
|
in GAE.
|
|
|
|
- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
|
|
module is the only object holding a reference to it.
|
|
|
|
- Issue #1754094: Improve the stack depth calculation in the compiler. There
|
|
should be no other effect than a small decrease in memory use. Patch by
|
|
Christopher Tur Lesniewski-Laas.
|
|
|
|
- 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 #1571184: The Unicode database contains properties for more characters.
|
|
The tables for code points representing numeric values, white spaces or line
|
|
breaks are now generated from the official Unicode Character Database files,
|
|
and include information from the Unihan.txt file.
|
|
|
|
- Issue #7050: Fix a SystemError when trying to use unpacking and augmented
|
|
assignment.
|
|
|
|
- Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence
|
|
running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
|
|
|
|
- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
|
|
producing internally inconsistent Python longs.
|
|
|
|
- Issue #6990: Fix ``threading.local`` subclasses leaving old state around after
|
|
a reference cycle GC which could be recycled by new locals.
|
|
|
|
- Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now
|
|
take keyword arguments.
|
|
|
|
- Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32
|
|
stream with a non-raising error handler like "replace" or "ignore".
|
|
|
|
- Issue #6713: Improve performance of base 10 int -> string and long -> string
|
|
conversions.
|
|
|
|
- Issue #1590864: Fix potential deadlock when mixing threads and fork().
|
|
|
|
- Issue #6844: Do not emit DeprecationWarnings when accessing a "message"
|
|
attribute on exceptions that was set explicitly.
|
|
|
|
- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
|
|
|
|
- ``classmethod()`` no longer checks if its argument is callable.
|
|
|
|
- Issue #6750: A text file opened with ``io.open()`` could duplicate its output
|
|
when writing from multiple threads at the same time.
|
|
|
|
- Issue #6704: Improve the col_offset in AST for "for" statements with a target
|
|
of tuple unpacking.
|
|
|
|
- Issue #6707: ``dir()`` on an uninitialized module caused a crash.
|
|
|
|
- Issue #6540: Fixed crash for ``bytearray.translate()`` with invalid parameters.
|
|
|
|
- Issue #6573: ``set.union()`` stopped processing inputs if an instance of self
|
|
occurred in the argument chain.
|
|
|
|
- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
|
|
|
|
- Issue #6070: On posix platforms import no longer copies the execute bit from
|
|
the .py file to the .pyc file if it is set. Patch by Marco N.
|
|
|
|
- Issue #4618: When unicode arguments are passed to ``print()``, the default
|
|
separator and end should be unicode also.
|
|
|
|
- Issue #6119: Fixed an incorrect Py3k warning about order comparisons of
|
|
built-in functions and methods.
|
|
|
|
- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
|
|
build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
|
|
of stdint.h on that platform.
|
|
|
|
- Issue #4856: Remove checks for win NT.
|
|
|
|
- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
|
|
arguments could be modified during the function call setup.
|
|
|
|
- Removed the ipaddr module.
|
|
|
|
- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
|
|
because it wasn't recognized as a sequence).
|
|
|
|
- Issue #6289: Encoding errors from ``compile()`` were being masked.
|
|
|
|
- When no module is given in a relative import, the module field of the
|
|
ImportFrom AST node is now None instead of an empty string.
|
|
|
|
- Assignment to None using import statements now raises a SyntaxError.
|
|
|
|
- Issue #4547: When debugging a very large function, it was not always possible
|
|
to update the lineno attribute of the current frame.
|
|
|
|
- Issue #5330: C functions called with keyword arguments were not reported by
|
|
the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
|
|
|
|
- Issue #5982: staticmethod and classmethod now expose the wrapped function with
|
|
``__func__``.
|
|
|
|
- Added support for multiple context managers in the same with-statement.
|
|
Deprecated ``contextlib.nested()`` which is no longer needed.
|
|
|
|
- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
|
|
statement and correctly lookup the __enter__ and __exit__ special methods.
|
|
|
|
- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
|
|
consistent with float("1e500") and interpretation of real and imaginary
|
|
literals.
|
|
|
|
- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
|
|
|
|
- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored
|
|
on classic classes and instances.
|
|
|
|
- Issue #5994: The marshal module now has docstrings.
|
|
|
|
- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
|
|
|
|
(1) inf and nan strings with trailing whitespace were incorrectly rejected;
|
|
(2) parsing of strings representing infinities and nans was locale aware; and
|
|
(3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
|
|
|
|
- Issue #5920: For ``float.__format__()``, change the behavior with the empty
|
|
presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
|
|
but with at least one decimal point and with a default precision
|
|
of 12. Previously, the behavior the same but with a default precision of 6.
|
|
This more closely matches ``str()``, and reduces surprises when adding
|
|
alignment flags to the empty presentation type. This also affects the new
|
|
complex.__format__ in the same way.
|
|
|
|
- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
|
|
classtype's, even if it was None. property now inserts the __doc__ into the
|
|
subclass instance __dict__.
|
|
|
|
- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
|
|
sequences. Patch by Nick Barnes and Victor Stinner.
|
|
|
|
- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
|
|
'.5')`` now produces a sensible result.
|
|
|
|
- Issue #5864: Fix empty format code formatting for floats so that it never
|
|
gives more than the requested number of significant digits.
|
|
|
|
- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new
|
|
Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
|
|
|
|
- Issue #4971: Fix titlecase for characters that are their own titlecase, but
|
|
not their own uppercase.
|
|
|
|
- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
|
|
_PyOS_double_to_string or PyOS_double_to_string.
|
|
|
|
- Issue #5283: Setting __class__ in __del__ caused a segfault.
|
|
|
|
- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
|
|
nans, infs or negative zeros.
|
|
|
|
- Implement PEP 378, Format Specifier for Thousands Separator, for floats, ints,
|
|
and longs.
|
|
|
|
- Issue #5515: 'n' formatting for ints, longs, and floats handles leading zero
|
|
formatting poorly.
|
|
|
|
- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
|

- Issue #3166: Make long -> float (and int -> float) conversions correctly
|
|
rounded.
|
|
|
|
- Issue #5787: ``object.__getattribute__(some_type, "__bases__")`` segfaulted on
|
|
some built-in types.
|
|
|
|
- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
|
|
giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.
|
|
|
|
- Issue #5759: float() didn't call __float__ on str subclasses.
|
|
|
|

|
|
|
|
- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to the end
|
|
sys.path, for compatibility with the system install of Python.
|
|
|
|
- Issue #4688: Add a heuristic so that tuples and dicts containing only
|
|
untrackable objects are not tracked by the garbage collector. This can reduce
|
|
the size of collections and therefore the garbage collection overhead on
|
|
long-running programs, depending on their particular use of datatypes.
|
|
|
|
- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its
|
|
performance. Long divisions and remainder operations are now between 50% and
|
|
150% faster.
|
|
|
|
- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
|
|
internal representation of integers, for performance reasons. Base 2**30 is
|
|
enabled by default on 64-bit machines. Add --enable-big-digits option to
|
|
configure, which overrides the default. Add sys.long_info structseq to
|
|
provide information about the internal format.
|
|
|
|
- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
|
|
result traceback.__members__ no longer exists.)
|
|
|
|

|
|
surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
|
|
== 2.
|
|
|
|
- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
|
|
{}'.format(1, 2) == '1 2'``.
|
|
|
|
- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
|
|
requirement. Means the DeprecationWarning from Python 2.6 can go away.
|
|
|
|
- Issue #5247: Improve error message when unknown format codes are used when
|
|
using ``str.format()`` with str, unicode, long, int, and float arguments.
|
|
|
|
- Running Python with the -3 option now also warns about classic division for
|
|
ints and longs.
|
|
|
|
- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
|
|
per long on a 32-bit system and 6 bytes per long on a 64-bit system.

|
|
rotating the object pointer by 4 bits to the right.

|
|
forces its argument to double before testing for infinity.
|
|
|
|
- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
|
|
|
|
- Issue #1242657: the __len__() and __length_hint__() calls in several tools
|
|
were suppressing all exceptions. These include list(), filter(), map(),
|
|
zip(), and bytearray().
|
|
|
|
- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
|
|
functions.
|
|
|
|
- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
|
|
OSError.
|
|
|
|
- Issue #4807: Port the _winreg module to Windows CE.
|
|
|
|
- Issue #4935: The overflow checking code in the expandtabs() method common to
|
|
str, bytes and bytearray could be optimized away by the compiler, letting the
|
|
interpreter segfault instead of raising an error.
|
|
|
|
- Issue #3720: Fix a crash when an iterator modifies its class and removes its
|
|
__next__ method.
|
|
|
|
- Issue #4893: Use NT threading on CE.
|
|
|
|
- Issue #4915: Port sysmodule to Windows CE.
|
|
|
|
- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
|
|
collecting the oldest generation) so that allocating lots of objects without
|
|
destroying them does not show quadratic performance. Based on a proposal by
|
|
Martin von Löwis at
|
|
http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
|
|
|
|
- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
|
|
|
|
- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
|
|
existing .py counterpart, override the co_filename attributes of all code
|
|
objects if the original filename is obsolete (which can happen if the file has
|
|
been renamed, moved, or if it is accessed through different paths). Patch by
|
|
Ziga Seilnacht and Jean-Paul Calderone.
|
|
|
|
- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
|
|
|
|
- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
|
|
file with `str' filename on Windows.
|
|
|
|
- Issue #3680: Reference cycles created through a dict, set or deque iterator
|
|
did not get collected.
|
|
|
|
- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
|
|
the tp_hash and tp_dict slots are both NULL.
|
|
|
|
- Issue #4764: With io.open, IOError.filename is set when trying to open a
|
|
directory on POSIX systems.
|
|
|
|
- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
|
|
systems.
|
|
|
|
- Issue #4759: None is now allowed as the first argument of
|
|
``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
|
|
|
|
- Added test case to ensure attempts to read from a file opened for writing
|
|
fail.
|
|
|
|
- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
|
|
elapsed times, not only when some objects are uncollectable/unreachable.
|
|
Original patch by Neil Schemenauer.
|
|
|
|
- Issue #3439: Add a bit_length method to int and long.
|
|
|
|
- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
|
|
patch by Neal Norwitz.
|
|
|
|
- Issue #4597: Fixed exception handling when the __exit__ function of a context
|
|
manager returns a value that cannot be converted to a bool.
|
|
|
|
- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
|
|
|
|
- Issue #4445: Replace ``sizeof(PyStringObject)`` with
|
|
``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
|
|
instances. On a typical machine this saves 3 bytes of memory (on average) per
|
|
string allocation.
|
|
|
|
- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
|
|
interpreter to abort ("Fatal Python error: Could not reset the stack!")
|
|
instead of throwing a MemoryError.
|
|
|
|
- Issue #3689: The list reversed iterator now supports __length_hint__ instead
|
|
of __len__. Behavior now matches other reversed iterators.
|
|
|
|
- Issue #4367: Python would segfault during compiling when the unicodedata
|
|
module couldn't be imported and \N escapes were present.
|
|
|
|
- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
|
|
file objects with closefd=False. The file descriptor is still kept open but
|
|
the file object behaves like a closed file. The ``FileIO`` object also got a
|
|
new readonly attribute ``closefd``.
|
|
|
|
- Issue #4348: Some bytearray methods returned that didn't cause any change to
|
|
the bytearray, returned the same bytearray instead of a copy.
|
|
|
|
- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
|
|
|
|
- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
|
|
|
|
- Issue #4048: The parser module now correctly validates relative imports.
|
|
|
|
- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
|
|
exec statement.
|
|
|
|
- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
|
|
does not return iterators for the 4th and 5th items.
|
|
|
|
- Issue #4209: Enabling unicode_literals and the print_function in the same
|
|
__future__ import didn't work.
|
|
|
|
- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
|
|
because it is a reserved word in 3.x.
|
|
|
|
- On windows, ``os.chdir()`` given unicode was not working if
|
|
GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
|
|
this code path is really executed because I cannot move to such directory on
|
|
win2k)
|
|
|
|
- Issue #4069: When ``set.remove(element)`` is used with a set element, the
|
|
element is temporarily replaced with an equivalent frozenset. But the
|
|
eventual KeyError would always report the empty ``frozenset()`` as the missing
|
|
key. Now it correctly refers to the initial element.
|
|
|
|
- Issue #4509: Various issues surrounding resize of bytearray objects to which
|
|
there are buffer exports.
|
|
|
|
- Issue #4748: Lambda generators no longer return a value.
|
|
|
|
- Issue #3582: Use native TLS functions on Windows
|
|
|

|
|
|
|
- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
|
|
file names.
|
|
|
|
- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
|
|
to avoid compiler warnings.
|
|
|
|
- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
|
|
returned them on 64bit platforms.
|
|
|
|
- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
|
|
PyUnicode_DecodeUTF8() once, remember the result and output it in a second
|
|
step. This avoids problems with counting UTF-8 bytes that ignores the effect
|
|
of using the replace error handler in PyUnicode_DecodeUTF8().
|
|
|
|
- Issue #3739: The unicode-internal encoder now reports the number of characters
|
|
consumed like any other encoder (instead of the number of bytes).
|
|
|
|
- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
|
|
allocator will be automatically disabled when running under Valgrind. This
|
|
gives improved memory leak detection when running under Valgrind, while taking
|
|
advantage of pymalloc at other times.

|
|
registry under Windows. Patch by Gabriel Genellina.

|
|
execute file paths that refer to source or compiled Python files as well as
|
|
zipfiles, directories and other valid sys.path entries that contain a
|
|
__main__.py file. This allows applications that run other Python scripts to
|
|
support the same flexibility as the CPython command line itself.
|
|
|
|
- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
|
|
connection with another process, rather than looping endlessly. The default
|
|
timeout is 20 seconds, which should be amply sufficient for local connections.
|
|
|
|

|
a modification is done through it. This fixes inconsistencies and test
|
|
failures on systems with slightly bogus mtime behaviour.
|
|
|
|
- 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 #7233: Fix a number of two-argument Decimal methods to make sure that

|
|
occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or

|
|
bug was not present in the pure Python implementation.

|
|
- Issue #6403: Fixed package path usage in build_ext.
|
|
|
|
- Issues #5155, #5313, #5331: multiprocessing.Process._bootstrap was

'<', '>'.
|
|
|
|
- Packing a float now always gives a Deprecation Warning. Previously it
|
|
only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
|
|
|
|
- If x is not an int, long or float, then packing x will always result in
|
|
struct.error. Previously an x with an __int__ method could be packed by
|
|
'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
|
|
__long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
|
|
neither __int__ nor __long__, TypeError used to be raised (with a
|
|
confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
|
|
struct.error in other cases.
|
|
|
|
Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
|
|
argument with an __int__ method can be packed, but use of this feature
|
|
triggers a DeprecationWarning.

|
- Issue #4873: Fix resource leaks in error cases of pwd and grp.
|
|
|
|
- Issue #4751: For hashlib algorithms provided by OpenSSL, the Python GIL is now
|
|
released during computation on data lengths >= 2048 bytes.
|
|
|
|
- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
|
|
supporting objects as input no matter how it was compiled (built in
|
|
implementations or external openssl library). NOTE: Undone in 2.7a2.
|
|
|

- Issue #4397: Fix occasional test_socket failure on OS X.
|
|
|
|
- Issue #4279: Fix build of parsermodule under Cygwin.
|
|
|
|
- Issue #4051: Prevent conflict of UNICODE macros in cPickle.

- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
|
|
|
|
- Issue #1040026: Fix os.times result on systems where HZ is incorrect.
|
|
|
|
- Issues #3167, #3682: Fix test_math failures for log, log10 on Solaris,
|
|
OpenBSD.
|
|
|
|
- Issue #4365: Add crtassem.h constants to the msvcrt module.
|
|
|
|
- Issue #4396: The parser module now correctly validates the with statement.
|
|
|
|
- Issue #5228: Make functools.partial objects can now be pickled.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- 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 #7312: Add a -F flag to run the selected tests in a loop until a test
|
|
fails. Can be combined with -j.
|
|
|
|
- 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.
|
|
|
|
- Issue #7222: Make thread "reaping" more reliable so that reference
|
|
leak-chasing test runs give sensible results. The previous method of reaping
|
|
threads could return successfully while some Thread objects were still
|
|
referenced. This also introduces a new private function: ``thread._count()``.
|
|
|
|
- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
|
|
runs the risk of causing the worker thread to fail.
|
|
|
|
- Issue #7055: test___all__ now greedily detects all modules which have an
|
|
__all__ attribute, rather than using a hardcoded and incomplete list.
|
|
|
|
- Issue #7058: Added save/restore for things like sys.argv and cwd to
|
|
runtest_inner in regrtest, with warnings if the called test modifies them,
|
|
and a new section in the summary report at the end.
|
|
|
|
- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
|
|
|
|
- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
|
|
off the trailing 0 in the version number.
|
|
|
|
- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
|
|
Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
|
|
the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
|
|
the tests if DISPLAY is defined but can't be used.
|
|
|
|
- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
|
|
regression tests in parallel, shortening the total runtime.
|
|
|
|
- Issue #5354: New test support function import_fresh_module() makes it easy to
|
|
import both normal and optimised versions of modules. test_heapq and
|
|
test_warnings have been adjusted to use it, tests for other modules with both
|
|
C and Python implementations in the stdlib can be adjusted to use it over
|
|
time.
|
|
|
|
- Fix test_warnings to no longer reset the warnings filter.
|
|
|
|
- Fix test_logging to no longer reset the warnings filter.
|
|
|
|
- Issue #5635: Fix running test_sys with tracing enabled.
|
|
|
|
- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
|
|
should cause a test to be skipped are now done using import_module from test
|
|
support, which does the conversion.
|
|
|
|
- Issue #5083: New 'gui' resource for regrtest.
|
|
|
|
- Issue #5837: Certain sequences of calls to set() and unset() for
|
|
support.EnvironmentVarGuard objects restored the environment variables
|
|
incorrectly on __exit__.
|
|
|
|
- Issue #2389: Array objects are now pickled in a portable manner.
|
|
|
|
Misc
|
|
----
|
|
|
|
- Issue #5611: Auto-detect whether a C file uses tabs or spaces in Vim.

|
|
- Issue #3965: Allow repeated calls to turtle.Screen, by making it a
|
|
true singleton object.
|
|
|
|
- Issue #3895: It was possible to crash the interpreter when an external timer

|
|
|
|
- Issue #3950: Made turtle respect scale factors.

=============================================
|
|
|
|
*Release date: 17-Sep-2008*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Security Issue #2: imageop did not validate arguments correctly and could
|
|
segfault as a result.
|
|
|
|
- Issue #3886: Possible integer overflows in the _hashopenssl module were
|
|
closed.
|
|
|
|
Tools/Demos
|
|
-----------
|
|
|
|
- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
|
|
AttributeError instead of RuntimeError, depending in which C API call
|
|
exactly the recursion limit is exceeded. Consequently, both exception types
|
|
are caught and silenced.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #3617: Include a licensing statement regarding the Microsoft

What's New in Python 2.6 release candidate 1?
|
|
=============================================
|
|
|
|
*Release date: 12-Sep-2008*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
|
|
|
|
- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
|
|
PyString_FromFormat or PyErr_Format to display size_t values. The macro
|
|
PY_FORMAT_SIZE_T is designed to select the correct format for the OS
|
|
``printf`` function, whereas PyString_FromFormat has an independent
|
|
implementation and uses "%zd" on all platforms for size_t values.
|
|
This makes a difference on win64, where ``printf`` needs "%Id" to display
|
|
64bit values.
|
|
|
|
- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
|
|
error.
|
|
|
|
- Issue #3777: long() applied to a float object now always return a long
|
|
object; previously an int would be returned for small values. the __long__
|
|
method is allowed to return either an int or a long, but the behaviour of
|
|
float objects should not change to respect backward compatibility.
|
|
|
|
- Issue #3751: str.rpartition would perform a left-partition when called with
|
|
a unicode argument.
|
|
|
|
- Issue #3683: Fix compilation when --without-threads is given.
|
|
|
|
- Issue #3668: Fix a memory leak with the "s*" argument parser in
|
|
PyArg_ParseTuple and friends, which occurred when the argument for "s*"
|
|
was correctly parsed but parsing of subsequent arguments failed.
|
|
|
|
- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
|
|
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
|
|
mechanism. In the process, fix a bug where isinstance() and issubclass(),
|
|
when given a tuple of classes as second argument, were looking up
|
|
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
|
|
type object.
|
|
|
|
- Fix crashes on memory allocation failure found with failmalloc.
|
|
|
|
- Fix memory leaks found with valgrind and update suppressions file.
|
|
|
|
- Fix compiler warnings in opt mode which would lead to invalid memory reads.
|
|
|
|
- Fix problem using wrong name in decimal module reported by pychecker.
|
|
|
|
- Silenced another compiler warning about a used but not defined
|
|
function 'stringlib_contains_obj'.
|
|
|
|
- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
|
|
``__delslice__``.
|
|
|
|
- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
|
|
library targets in the Makefile.
|
|
|
|
- Issue #1204: The configure script now tests for additional libraries
|
|
that may be required when linking against readline. This fixes issues
|
|
with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
|
|
|
|
C-API
|
|
-----
|
|
|
|
- Aliased PyObject_Bytes to PyObject_Str.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
|
|
stack usage in the case of deeply nested objects.
|
|
|
|
- Issue #3629: Fix sre "bytecode" validator for an end case.
|
|
|
|
- Issue #3811: The Unicode database was updated to 5.1.
|
|
|
|
- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
|
|
silent misbehaviour when a single instance is nested in multiple
|
|
with statements, or when the methods are invoked in the wrong order.
|
|
|
|
- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
|
|
|
|
- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
|
|
return a list or None rather than a custom object.
|
|
|
|
- Issue #1638033: Cookie.Morsel gained the httponly attribute.
|
|
|
|
- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
|
|
|
|
- Issue #3776: Deprecate the bsddb package for removal in 3.0.
|
|
|
|
- Issue #3762: platform.architecture() fails if python is lanched via
|
|
its symbolic link.
|
|
|
|
- Issue #3772: Fixed regression problem in StreamHandler.emit().
|
|
|
|
- Issue #600362: Relocated parse_qs() and parse_qsl(), from the cgi module
|
|
to the urlparse one. Added a PendingDeprecationWarning in the old
|
|
module, it will be deprecated in the future.
|
|
|
|
- Issue #2562: Fix distutils PKG-INFO writing logic to allow having
|
|
non-ascii characters and Unicode in setup.py meta-data.
|
|
|
|
- Issue #3726: Allow spaces in separators in logging configuration files.
|
|
|
|
- Issue #3719: platform.architecture() fails if there are spaces in the
|
|
path to the Python binary.
|
|
|
|
- Issue #3602: Moved test.test_support.catch_warning() to
|
|
warnings.catch_warnings() along with some API cleanup. Expanding the tests
|
|
for catch_warnings() also led to an improvement in the raising of a
|
|
DeprecationWarning related to warnings.warn_explicit().
|
|
|
|
- The deprecation warnings for the old camelCase threading API were removed.
|
|

|
|
non-integer floating point number.
|
|
|
|
- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing
|
|
SEM_VALUE_MAX.
|

|
|
|
- Issue #4301: Patch the logging module to add processName support, remove
|
|
_check_logger_class from multiprocessing.
|
|

|
|
from the same python interpreter, some environment variables would grow
|
|
without limit.
|
|
|

|
exploitation of poor argument checking.
|
|
|

|
-----
|
|
|
|

What's New in Python 2.6 beta 3?
|
|
================================
|
|
|
|
*Release date: 20-Aug-2008*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
|
|
Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
|
|
extensions do not automatically benefit from the class attribute
|
|
cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
|
|
to their tp_flags field if they care. This is a backwards
|
|
compatibility feature; in 3.0, all types will use the cache by
|
|
default.
|
|
|
|
- Keyword arguments can now follow starred arguments. (``f(a, *args,
|
|
keyword=23)`` is now valid syntax.)
|
|
|
|
- ctypes function pointers that are COM methods have a boolean True
|
|
value again.
|
|
|
|
- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
|
|
by denying s# to parse objects that have a releasebuffer procedure,
|
|
and introducing s*.
|
|
|
|
- Issue #3537: Fix an assertion failure when an empty but presized dict
|
|
object was stored in the freelist.
|
|
|
|
- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
|
|
ValueError consistently across platforms.
|
|
|
|
- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
|
|
(64bit Unix, for example), unichr() would truncate its argument and return
|
|
u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
|
|
|
|
- Apply security patches from Apple.
|
|
|
|
- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
|
|
PyErr_ExceptionMatches returns 0 when an exception occurs there.
|
|
|
|
- Issue #1819: function calls with several named parameters are now on
|
|
average 35% faster (as measured by pybench).
|
|
|
|
- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
|
|
the python debugger steps into a class statement: the free variables (local
|
|
variables defined in an outer scope) would be deleted from the outer scope.
|
|
|
|
- Issue #2620: Overflow checking when allocating or reallocating memory
|
|
was not always being done properly in some python types and extension
|
|
modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
|
|
all been updated to perform better checks and places in the code that
|
|
would previously leak memory on the error path when such an allocation
|
|
failed have been fixed.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #3612: Added some missing basic types in ctypes.wintypes.
|
|
|
|
- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
|
|
symtable.Symbol have been deprecated for removal in 3.0 and the next release.
|
|
|
|
- Issue #2234: distutils failed for some versions of the cygwin compiler. The
|
|
version reported by these tools does not necessarily follow the python
|
|
version numbering scheme, so the module is less strict when parsing it.
|
|
|
|
- Issue #2235: Added Py3k warnings for types which will become unhashable
|
|
under the stricter __hash__ inheritance rules in 3.0. Several types
|
|
which did not meet the rules for hash invariants and were already
|
|
unhashable in 3.0 have now been explicitly flagged as unhashable in
|
|
2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
|
|
xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
|
|
|
|
- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
|
|
imported into the module but exposed as part of the module's API.
|
|
|
|
- Remove an unneeded import of abc.ABCMeta from 'inspect'.
|
|
|
|
- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
|
|
|
|
- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
|
|
|
|
- Issue #3575: Incremental decoder's decode function now takes bytearray
|
|
by using 's*' instead of 't#'.
|
|
|
|
- Issue #2222: Fixed reference leak when occurred os.rename()
|
|
fails unicode conversion on 2nd parameter. (windows only)
|
|
|
|
- Issue #2464: urllib2 now supports a malformation in the URL received
|
|
in a redirect.
|
|
|
|
- Silence the DeprecationWarning raised when importing mimetools in
|
|
BaseHTTPServer, cgi (and rfc822), httplib.
|
|
|
|
- Issue #2776: fixed small issue when handling an URL with double slash
|
|
after a 302 response in the case of not going through a proxy.
|
|
|
|
- Issue #2676: in the email package, content-type parsing was hanging on
|
|
pathological input because of quadratic or exponential behaviour of a
|
|
regular expression.
|
|
|
|
- Issue #3476: binary buffered reading through the new "io" library is now
|
|
thread-safe.
|
|
|
|
- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
|
|
since mimetools itself is deprecated. Because modules are cached, all
|
|
subsequent imports of rfc822 will not raise a visible DeprecationWarning.
|
|
|
|
- Issue #3134: shutil referenced undefined WindowsError symbol.
|
|
|
|
- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
|
|
menu entries were not deleted.
|
|
|
|
- Copied the implementation of reduce() to _functools.reduce() to have a

|
|
|
|
- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
|

|
|
|
|

|
|
raised an AttributeError.
|
|
|

|
file name rather than a ZipInfo instance, so files are extracted with

|
mode 0600 rather than 000 under Unix.
|
|
|
|
- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
|

What's New in Python 2.6 beta 2?
|
|
================================
|
|
|
|
*Release date: 17-Jul-2008*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #3156: Fix inconsistent behavior of the bytearray type: all
|
|
its methods now allow for items objects that can be converted to
|
|
an integer using operator.index().
|
|
|
|
- Issue #3360: Fix incorrect parsing of '020000000000.0', which
|
|
produced a ValueError instead of giving the correct float.
|
|
|
|
- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
|
|
for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
|
|
|
|
- Issue #3008: the float type has a new instance method 'float.hex'
|
|
and a new class method 'float.fromhex' to convert floating-point
|
|
numbers to and from hexadecimal strings, respectively.
|
|
|
|
- Issue #2235: __hash__ is once again inherited by default. To allow
|
|
collections.Hashable to remain meaningful in the presence of the
|
|
default hash implementation (object.__hash__), it is now possible
|
|
to explicit block inheritance of hash by setting __hash__=None at
|
|
the Python level, or tp_hash=PyObject_HashNotImplemented at the C
|
|
level.
|
|
|
|
- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
|
|
the parent module cannot be found while performing an absolute import.
|
|
This means that an incorrectly defined __package__ attribute will
|
|
now only prevent relative imports in that module rather than causing
|
|
all imports from that module to fail.
|
|
|
|
- Issue #2517: Allow unicode messages in Exceptions again by correctly
|
|
bypassing the instance dictionary when looking up __unicode__ on
|
|
new-style classes.
|
|
|
|
- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
|
|
set to a custom object whose write() method happens to install
|
|
another file in sys.stdout.
|
|
|
|
- Issue #3088: Corrected a race condition in classes derived from
|
|
threading.local: the first member set by a thread could be saved in
|
|
another thread's dictionary.
|
|
|
|
- Issue #3004: Minor change to slice.indices(): the start and stop
|
|
arguments are now treated identically, making the behaviour easier
|
|
to describe and understand. For example, slice(None, -10,
|
|
1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
|
|
slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
|
|
10, -1).
|
|
|
|
- Issue #3219: Calling a function with repeated keyword arguments,
|
|
f(a=2, a=23), would not cause a syntax error. This was a regression
|
|
from 2.4 caused by the switch to the new compiler.
|
|
|
|
- Issue #2862: Make int and float freelist management consistent with
|
|
other freelists. Changes their CompactFreeList apis into
|
|
ClearFreeList apis and calls them via gc.collect().
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
|
|
api functions without holding the GIL, which could lead to a fatal
|
|
error when they failed.
|
|
|
|
- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
|
|
|
|
- Issue #3395: fix reference in test_multiprocessing to old debugInfo method
|
|
|
|
- Issue #3312: Fix two crashes in sqlite3.
|
|
|
|
- Issue #1608818: Fix misbehavior in os.listdir() if readdir() fails.
|
|
|
|
- Issue #3125: Remove copy_reg in multiprocessing and replace it with
|
|
ForkingPickler.register() to resolve conflict with ctypes.
|
|
|
|
- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
|
|
|
|
- Issue #3313: Fixed a crash when a failed dlopen() call does not set
|
|
a valid dlerror() message.
|
|
|
|
- Issue #3258: Fixed a crash when a ctypes POINTER type to an
|
|
incomplete structure was created.
|
|
|
|

|
|
|
|
- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
|
|
|
|
- Issue #3301: Bisect module behaved badly when lo was negative.
|
|
|
|
- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
|
|
both unnecessary (HTTP allows text content to be sent in several forms) and
|
|
wrong because the actual transmitted size could differ from the
|
|
content-length. The problem had been corrected in the 2.4 branch, but never
|
|
merged into trunk.
|
|
|
|
- Issue #2663: add filtering capability to shutil.copytree().
|
|
|
|
- Issue #1622: Correct interpretation of various ZIP header fields.
|
|
|
|
- Issue #1526: Allow more than 64k files to be added to Zip64 file.
|
|
|
|
- Issue #1746: Correct handling of zipfile archive comments (previously
|
|
archives with comments over 4k were flagged as invalid). Allow writing
|
|
Zip files with archives by setting the 'comment' attribute of a ZipFile.
|
|
|
|
- Issue #449227: The rlcompleter module now adds "(" to callable objects
|
|
when completed.
|
|
|
|
- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
|
|
handling is now the same as that of other special attributes like __name__).
|
|
|
|
- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
|
|
removal in Python 3.0 in favor of urllib2.urlopen().
|
|
|
|
- Issue #2113: Fix error in subprocess.Popen if the select system call is
|
|
interrupted by a signal.
|
|
|
|
- Issue #3309: Fix bz2.BZFile iterator to release its internal lock
|
|
properly when raising an exception due to the bz2file being closed.
|
|
Prevents a deadlock.
|
|
|
|
- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
|
|
redundant ":443" port number designation when the connection is using the
|
|
default https port (443).
|
|
|
|
- Issue #874900: after an os.fork() call the threading module state is cleaned
|
|
up in the child process to prevent deadlock and report proper thread counts
|
|
if the new process uses the threading module.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- test.test_support.catch_warning now keeps track of all warnings it sees
|
|
and is now better documented. Explicit unit tests for this context manager
|
|
have been added to test_warnings.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd.
|
|
|
|
|
|

|
|
================================
|
|
|
|
*Release date: 18-June-2008*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #3211: warnings.warn_explicit() did not guard against its 'registry'
|
|
argument being anything other than a dict or None. Also fixed a bug in error
|
|
handling when 'message' and 'category' were both set to None, triggering a
|
|
bus error.
|
|
|
|
- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
|
|
holds the last (strong) reference to its referent.
|
|
|
|
- Add future_builtins.ascii().
|
|
|

|
|
intersection(), intersection_update(), difference(), and difference_update().
|
|
|
|
- Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes.
|
|
|
|
- New environment variable PYTHONIOENCODING.
|
|
|
|
- Patch #2488: Add sys.maxsize.

|
|
|
- Issue #2353: file.xreadlines() now emits a Py3k warning.
|
|

|
|
equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals
|
|
``func.func_code.co_name``. The repr() of a generator now also
|
|
contains this name.
|
|
|
|
- Issue #2831: enumerate() now has a ``start`` argument.
|
|
|
|
- Issue #2801: fix bug in the float.is_integer method where a
|
|
ValueError was sometimes incorrectly raised.

|
|
attribute.
|
|
|

|
|
Exception (KeyboardInterrupt, and SystemExit) propagate instead of
|
|
ignoring them.
|
|
|
|
- Added checks for integer overflows, contributed by Google. Some are
|
|
only available if asserts are left in the code, in cases where they
|
|
can't be triggered from Python code.

|
|

|
|
|
|

|
|

|
|
the patch.
|
|
|
|
- Issue #3126: StreamHandler and FileHandler check before calling "flush" and

|
|
|
|
- Issue #2912: platform.uname now tries to determine unknown information even if
|
|
os.uname exists.

|
|
mode or even as a 4-way universal binary (that is, PPC, i386,
|
|
PPC64 and x86_64 support in one binary).
|
|
|
|
This is controlled by the configure argument ``--with-universal-archs``:
|
|
|
|
- ``--with-universal-archs=all``: install 4-way universal
|
|
|
|
- ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
|
|
|
|
- ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
|
|
|
|
This option should be used in combination with ``--enable-universalsdk=``.
|
|
|
|
NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

|
|
|
|
- The PyString functions have been renamed to PyBytes. A batch of
|
|
defines were added so that the linker still sees the original
|
|
PyString names.

What's New in Python 2.6 alpha 3?
|
|
=================================
|
|
|
|
*Release date: 08-May-2008*
|
|
|
|
Core and builtins
|
|
-----------------
|
|
|
|
- Issue #2719: backported the ``next()`` builtin from Python 3.
|
|
|
|
- Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now
|
|
it properly raises a SyntaxError.
|
|
|
|
- Issue #2617: Reserved -J and -X arguments for Jython, IronPython and
|
|
other implementations of Python.
|
|
|
|
- Implemented PEP 370: Per user site-packages directory.
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
|
|
two handlers that derive the same default base class.
|
|
|
|
- Added kill, terminate and send_signal(sig) to subprocess.Popen.
|
|
|
|
- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
|
|
the cmath module.
|
|
|
|
- Four new methods were added to the math and cmath modules: acosh,
|
|
asinh, atanh and log1p.
|
|
|
|
- zlib.decompressobj().flush(value) no longer crashes the interpreter
|
|
when passed a value less than or equal to zero.
|
|
|
|
- Issue #1631171: Re-implement the 'warnings' module in C (the
|
|
original Python code has been kept as backup). This will allow for
|
|
using the 'warning's machinery in such places as the parser where
|
|
use of pure Python code is not possible. Both the ``showarning()``
|
|
and ``formatwarning()`` gain an optional 'line' argument which is
|
|
not called by default for backwards-compatibility reasons. Setting
|
|
``warnings.showwarning()`` to an implementation that lacks support
|
|
for the ``line`` argument will raise a DeprecationWarning.
|
|
|
|
Library
|
|
-------
|
|
|
|
- The audiodev module has been deprecated for removal in Python 3.0.
|
|
|
|
- Issue #2750: Add the 'json' package. Based on simplejson 1.9 and
|
|
contributed by Bob Ippolito.
|
|
|
|
- Issue #1734346: Support Unicode file names for zipfiles.
|
|
|
|
- Issue #2581: distutils: Vista UAC/elevation support for
|
|
bdist_wininst.
|
|
|
|
- Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option,
|
|
where an extra space was added after a word containing (but not
|
|
ending in) '.', '!' or '?'.
|
|
|
|
- Add from_buffer() and from_buffer_copy() class methods to ctypes
|
|
data types.
|
|
|
|
- Issue #2682: ctypes callback functions no longer contain a cyclic
|
|
reference to themselves.
|
|
|
|
- The getpass module has been improved on Unix. It now uses /dev/tty
|
|
by default and uses stderr instead of stdout. A GetPassWarning is
|
|
issued when input echo cannot be controlled.
|
|
|
|
- Issue #2014: Allow XML-RPC datetime objects to have dates before
|
|
1900-01-01.
|
|
|
|
- Issue #2439: Added new function pkgutil.get_data(), which is a
|
|
convenience wrapper for the PEP 302 get_data() API.
|
|
|
|
- Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are
|
|
now implemented in C for better performance.
|
|
|
|
- Issue #2408: The ``_types`` module, which was used as in
|
|
implementation detail of the public ``types`` module, has been
|
|
removed and replaced by pure python code.
|
|
|
|
- Issue #2513: distutils on Windows is now capable of cross-compiling
|
|
extension modules between 32 and 64 bit platforms. See the distutls
|
|
build documentation for more information.
|
|
|
|
- Issue #815646: Individual file objects may now be used from multiple
|
|
threads at once without fear of crashing the Python interpreter. If
|
|
file.close() is called while an object is in use by another thread
|
|
an IOError exception will be raised and the file will not be closed.
|
|
|
|
- The bundled libffi copy is now in sync with the recently released
|
|
libffi3.0.5 version, apart from some small changes to
|
|
Modules/_ctypes/libffi/configure.ac.
|
|
|
|
- Issue #2385: distutils.core.run_script() makes __file__ available,
|
|
so the controlled environment will more closely mirror the typical
|
|
script environment. This supports setup.py scripts that refer to
|
|
data files.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- Issue #2550: The approach used by client/server code for obtaining
|
|
ports to listen on in network-oriented tests has been refined in an
|
|
effort to facilitate running multiple instances of the entire
|
|
regression test suite in parallel without issue.
|
|
test_support.bind_port() has been fixed such that it will always
|
|
return a unique port -- which wasn't always the case with the
|
|
previous implementation, especially if socket options had been set
|
|
that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
|
|
new implementation of bind_port() will actually raise an exception
|
|
if it is passed an AF_INET/SOCK_STREAM socket with either the
|
|
SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
|
|
available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
|
|
the socket it's been passed. This currently only applies to
|
|
Windows. This option prevents any other sockets from binding to the
|
|
host/port we've bound to, thus removing the possibility of the
|
|
'non-deterministic' behaviour, as Microsoft puts it, that occurs
|
|
when a second SOCK_STREAM socket binds and accepts to a host/port
|
|
that's already been bound by another socket. The optional preferred
|
|
port parameter to bind_port() has been removed. Under no
|
|
circumstances should tests be hard coding ports!
|
|
|
|
test_support.find_unused_port() has also been introduced, which will
|
|
pass a temporary socket object to bind_port() in order to obtain an
|
|
unused port. The temporary socket object is then closed and
|
|
deleted, and the port is returned. This method should only be used
|
|
for obtaining an unused port in order to pass to an external program
|
|
(i.e. the -accept [port] argument to openssl's s_server mode) or as
|
|
a parameter to a server-oriented class that doesn't give you direct
|
|
access to the underlying socket used.
|
|
|
|
Finally, test_support.HOST has been introduced, which should be used
|
|
for the host argument of any relevant socket calls (i.e. bind and
|
|
connect).
|
|
|
|
The following tests were updated to following the new conventions:
|
|
test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
|
|
test_poplib, test_ftplib, test_telnetlib, test_socketserver,
|
|
test_asynchat and test_socket_ssl.
|
|
|
|
It is now possible for multiple instances of the regression test
|
|
suite to run in parallel without issue.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #1496032: On alpha, use -mieee when gcc is the compiler.
|
|
|
|
- Issue #2544: On HP-UX systems, use 'gcc -shared' for linking when
|
|
gcc is used as compiler.
|
|
|
|
- Issue #2573: On MacOS X it is now possible to install the framework
|
|
with a different name using --with-framework-name=NAME.
|
|
|
|
C API
|
|
-----
|
|
|
|
- Added implementation of copysign, acosh, asinh, atanh and log1p to
|
|
the new files Include/pymath.h and Python/pymath.h for platforms
|
|
which provide the functions through their libm. The files also
|
|
contains several helpers and constants for math.
|
|
|
|
- Added a new convenience macro, PyErr_WarnPy3k, for issuing Py3k warnings.
|
|
|

Core and builtins
|
|
-----------------
|
|
|
|
- Issue #1733757: The interpreter would hang on shutdown if the
|
|
tracing function set by sys.settrace is still active and happens to

|
|
- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
|
|
cannot be executed.
|
|
|
|

'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
|
|
this case, like normal unicode literals and the 'unicode-escape'
|
|
codec.
|
|
|
|
- Issue #2348: add Py3k warning for file.softspace.
|

memory usage in some circumstances.
|
|
|
|
- PEP 3127: octal literals now start with "0o". Old-style octal
|
|
literals are still valid. There are binary literals with a prefix of
|
|

|
|
|
- Issue #2359: Adding deprecation warnings for array.{read,write}.
|
|
|
|
- Issue #1779871: GNU gcc can now build Python on OS X because the

|
|
improved logic for removing old files.
|
|
|
|
- Issue #2495: tokenize.untokenize now inserts a space between two
|

- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
|
|
optional: it defaults to the traceback of the exception that is
|
|
currently being handled (is mandatory to be in the middle of an
|
|
exception, otherwise it raises ValueError).
|
|
|
|
- Issue #1193577: A .shutdown() method has been added to SocketServers
|
|
which terminates the .serve_forever() loop.
|
|
|

|
|
|
- The bundled libffi copy is now in sync with the recently released
|
|
libffi3.0.4 version, apart from some small changes to
|
|
Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
|
|
files are used. On all linux systems the --with-system-ffi
|
|
configure option defaults to "yes".
|
|
|
|
- Issue #1577: shutil.move() now calls os.rename() if the destination
|
|
is a directory instead of copying-then-remove-source.
|
|
|
|

What's New in Python 2.6 alpha 1?
|
|
=================================
|
|
|
|
*Release date: 29-Feb-2008*
|
|
|
|
Core and builtins
|
|
-----------------
|
|
|
|
- Issue #2051: pyc and pyo files are no longer created with permission
|
|
644. The mode is now inherited from the py file.
|
|
|
|
- Issue #2067: file.__exit__() now calls subclasses' close() method.
|
|
|
|
- Patch #1759: Backport of PEP 3129 class decorators.
|
|
|
|
- Issue #1881: An internal parser limit has been increased. Also see
|
|
issue #215555 for a discussion.
|
|
|
|
- Added the future_builtins module, which contains hex() and oct().
|
|
These are the PEP 3127 version of these functions, designed to be
|
|
compatible with the hex() and oct() builtins from Python 3.0. They
|
|
differ slightly in their output formats from the existing, unchanged
|
|
Python 2.6 builtins. The expected usage of the future_builtins
|
|
module is:
|
|
from future_builtins import hex, oct
|
|
|
|
- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
|
|
exponents for exponents with absolute value < 100. Follows C99
|
|
standard. This is a change on Windows, which would use 3 digits.
|
|
Also, added 'n' to the formats that PyOS_ascii_formatd understands,
|
|
so that any alterations it does to the resulting string will be
|
|
available in stringlib/formatter.h (for float.__format__).
|
|
|
|
- Implemented PEP 3101, Advanced String Formatting. This adds a new
|
|
builtin format(); a format() method for str and unicode; a
|
|
__format__() method to object, str, unicode, int, long, float, and
|
|
datetime; the class string.Formatter; and the C API
|
|
PyObject_Format().
|
|
|
|
- Fixed several potential crashes, all caused by specially crafted
|
|
__del__ methods exploiting objects in temporarily inconsistent
|
|
state.
|
|
|
|
- Issue #2115: Important speedup in setting __slot__ attributes. Also
|
|
prevent a possible crash: an Abstract Base Class would try to access
|
|
a slot on a registered virtual subclass.
|
|
|
|
- Fixed repr() and str() of complex numbers with infinity or nan as
|
|
real or imaginary part.
|
|
|
|
- Clear all free lists during a gc.collect() of the highest generation
|
|
in order to allow pymalloc to free more arenas. Python may give back
|
|
memory to the OS earlier.
|
|
|
|
- Issue #2045: Fix an infinite recursion triggered when printing a
|
|
subclass of collections.defaultdict, if its default_factory is set
|
|
to a bound method.
|
|
|
|
- Fixed a minor memory leak in dictobject.c. The content of the free
|
|
list was not freed on interpreter shutdown.
|
|
|
|
- Limit free list of method and built-in function objects to 256
|
|
entries each.
|
|
|
|
- Patch #1953: Added ``sys._compact_freelists()`` and the C API
|
|
functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
|
|
to compact the internal free lists of pre-allocted ints and floats.
|
|
|
|
- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
|
|
calls. Python expected the return type int but the fork familie
|
|
returns pi_t.
|
|
|
|
- Issue #1678380: Fix a bug that identifies 0j and -0j when they
|
|
appear in the same code unit.
|
|
|
|
- Issue #2025: Add tuple.count() and tuple.index() methods to comply
|
|
with the collections.Sequence API.
|
|
|
|
- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
|
|
linebreak detection
|
|
|
|
- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
|
|
the internal lookup cache for ref leak tests.
|
|
|
|
- Patch #1473257: generator objects gain a gi_code attribute. This is
|
|
the same object as the func_code attribute of the function that
|
|
produced the generator.
|
|
|
|
- Issue #1920: "while 0" statements were completely removed by the
|
|
compiler, even in the presence of an "else" clause, which is
|
|
supposed to be run when the condition is false. Now the compiler
|
|
correctly emits bytecode for the "else" suite.
|
|
|
|
- A few crashers fixed: weakref_in_del.py (issue #1377858);
|
|
loosing_dict_ref.py (issue #1303614, test67.py);
|
|
borrowed_ref_[34].py (not in tracker).
|
|
|
|
- Issue #1069410: The "can't load dll" message box on Windows is
|
|
suppressed while an extension is loaded by calling SetErrorMode in
|
|
dynload_win.c. The error is still reported properly.
|
|
|
|
- Issue #1915: Python compiles with --enable-unicode=no again. However
|
|
several extension methods and modules do not work without unicode
|
|
support.
|
|
|
|
- Issue #1882: when compiling code from a string, encoding cookies in the
|
|
second line of code were not always recognized correctly.
|
|
|
|
- Issue #1679: "0x" was taken as a valid integer literal.
|
|
|
|
- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
|
|
added.
|
|
|
|
- sys.float_info / PyFloat_GetInfo: The floating point information
|
|
object was converted from a dict to a specialized structseq object.
|
|
|
|
- Patch #1816: Added sys.flags structseq. It exposes the status of
|
|
most command line arguments and PYTHON* environment variables.
|
|
|
|
- Objects/structseq.c: Implemented new structseq representation. The
|
|
patch makes structseqs (e.g. the return value of os.stat) more
|
|
readable.
|
|
|
|
- Patch #1700288: added a type attribute cache that caches method
|
|
accesses, resulting in speedups in heavily object-oriented code.
|
|
|
|
- Bug #1776: __import__() no longer accepts filenames on any platform.
|
|
The first parameter to __import__() must be a valid module name.
|
|
|
|
- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
|
|
|
|
- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
|
|
envvar and sys.dont_write_bytecode attribute. All these can be set
|
|
to forbid Python to attempt to write compiled bytecode files.
|
|
|
|
- Improve some exception messages when Windows fails to load an
|
|
extension module. Now we get for example '%1 is not a valid Win32
|
|
application' instead of 'error code 193'.
|
|
|
|
- Bug #1481296: Fixed long(float('nan')) != 0L.
|
|
|
|
- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
|
|
y) functions.
|
|
|
|
- Issue #1635: Platform independent creation and representation of NaN
|
|
and INF. float("nan"), float("inf") and float("-inf") now work on
|
|
every platform with IEEE 754 semantics.
|
|
|
|
- Compiler now generates simpler and faster code for dictionary
|
|
literals. The oparg for BUILD_MAP now indicates an estimated
|
|
dictionary size. There is a new opcode, STORE_MAP, for adding
|
|
entries to the dictionary.
|
|
|
|
- Issue #1638: %zd configure test fails on Linux.
|
|
|
|
- Issue #1620: New property decorator syntax was modifying the
|
|
decorator in place instead of creating a new decorator object.
|
|
|
|
- Issue #1538: Avoid copying string in split/rsplit if the split char
|
|
is not found.
|
|
|
|
- Issue #1553: An erroneous __length_hint__ can make list() raise a
|
|
SystemError.
|
|
|
|
- PEP 366: Allow explicit relative imports when executing modules
|
|
inside packages with the -m switch via a new module level
|
|
__package__ attribute.
|
|
|
|
- Issue #1402: Fix a crash on exit, when another thread is still
|
|
running, and if the deallocation of its frames somehow calls the
|
|
PyGILState_Ensure() / PyGILState_Release() functions.
|
|
|
|
- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
|
|
|
|
- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
|
|
attribute of an empty cell object.
|
|
|
|
- Issue #1460: The utf-7 incremental decoder did not accept truncated
|
|
input. It now correctly saves its state between chunks of data.
|
|
|
|
- Patch #1739468: Directories and zipfiles containing a __main__.py
|
|
file can now be directly executed by passing their name to the
|
|
interpreter. The directory/zipfile is automatically inserted as the
|
|
first entry in sys.path.
|
|
|
|
- Issue #1265: Fix a problem with sys.settrace, if the tracing
|
|
function uses a generator expression when at the same time the
|
|
executed code is closing a paused generator.
|
|
|
|
- sets and frozensets now have an isdisjoint() method.
|
|
|
|
- optimize the performance of builtin.sum().
|
|
|
|
- Fix warnings found by the new version of the Coverity checker.
|
|
|
|
- The enumerate() built-in function is no longer bounded to sequences
|
|
smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
|
|
automatically shifts from ints to longs.
|
|
|
|
- Issue #1686386: Tuple's tp_repr did not take into account the
|
|
possibility of having a self-referential tuple, which is possible
|
|
from C code. Nor did object's tp_str consider that a type's tp_str
|
|
could do something that could lead to an inifinite recursion.
|
|
Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
|
|
issues.
|
|
|
|
- Issue #1164: It was possible to trigger deadlock when using the
|
|
'print' statement to write to a file since the GIL was not released
|
|
as needed. Now PyObject_Print() does the right thing along with
|
|
various tp_print implementations of the built-in types and those in
|
|
the collections module.
|
|
|
|
- Issue #1147: Exceptions were directly allowing string exceptions in
|
|
their throw() method even though string exceptions no longer
|
|
allowed.
|
|
|
|
- Issue #1096: Prevent a segfault from getting the repr of a very
|
|
deeply nested list by using the recursion counter.
|
|
|
|
- Issue #1202533: Fix infinite recursion calls triggered by calls to
|
|
PyObject_Call() never calling back out to Python code to trigger
|
|
recursion depth updates/checks. Required the creation of a static
|
|
RuntimeError instance in case normalizing an exception put the
|
|
recursion check value past its limit. Fixes crashers
|
|
infinite_rec_(1|2|4|5).py.
|
|
|
|
- Patch #1031213: Decode source line in SyntaxErrors back to its
|
|
original source encoding.
|
|
|
|
- Patch #1673759: add a missing overflow check when formatting floats
|
|
with %G.
|
|
|
|
- Prevent expandtabs() on string and unicode objects from causing a
|
|
segfault when a large width is passed on 32-bit platforms.
|
|
|
|
- Issue #1733488: Fix compilation of bufferobject.c on AIX.
|
|
|
|
- Issue #1722485: remove docstrings again when running with -OO.
|
|
|
|
- Add new attribute names for function objects. All the func_* become
|
|
__*__ attributes. (Some already existed, e.g., __doc__ and
|
|
__name__.)
|
|
|
|
- Add -3 option to the interpreter to warn about features that are
|
|
deprecated and will be changed/removed in Python 3.0.
|
|
|
|
- Patch #1686487: you can now pass any mapping after '**' in function
|
|
calls.
|
|
|
|
- except clauses may now be spelled either "except E, target:" or
|
|
"except E as target:". This is to provide forwards compatibility
|
|
with Python 3.0.
|
|
|
|
- Deprecate BaseException.message as per PEP 352.
|
|
|
|
- Issue #1303614: don't expose object's __dict__ when the dict is
|
|
inherited from a built-in base.
|
|
|
|
- When __slots__ are set to a unicode string, make it work the same as
|
|
setting a plain string, ie don't expand to single letter identifiers.
|
|
|
|
- Request #1191699: Slices can now be pickled.
|
|
|
|
- Request #1193128: str.translate() now allows a None argument for
|
|
translations that only remove characters without re-mapping the
|
|
remaining characters.
|
|
|
|
- Patch #1682205: a TypeError while unpacking an iterable is no longer
|
|
masked by a generic one with the message "unpack non-sequence".
|
|
|
|
- Remove unused file Python/fmod.c.
|
|
|
|
- Bug #1683368: The object.__init__() and object.__new__() methods are
|
|
now stricter in rejecting excess arguments. The only time when
|
|
either allows excess arguments is when it is not overridden and the
|
|
other one is. For backwards compatibility, when both are
|
|
overridden, it is a deprecation warning (for now; maybe a Py3k
|
|
warning later). Also, type.__init__() insists on the same signature
|
|
as supported by type.__new__().
|
|
|
|
- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
|
|
object to complex using its __complex__() method before falling back
|
|
to the __float__() method. Therefore, the functions in the cmath
|
|
module now can operate on objects that define a __complex__()
|
|
method.
|
|
|
|
- Patch #1623563: allow __class__ assignment for classes with
|
|
__slots__. The old and the new class are still required to have the
|
|
same slot names.
|
|
|
|
- Patch #1642547: Fix an error/crash when encountering syntax errors
|
|
in complex if statements.
|
|
|
|
- Patch #1462488: Python no longer segfaults when
|
|
``object.__reduce_ex__()`` is called with an object that is faking
|
|
its type.
|
|
|
|
- Patch #1680015: Don't modify __slots__ tuple if it contains an
|
|
unicode name.
|
|
|
|
- Patch #1444529: the builtin compile() now accepts keyword arguments.
|
|
|
|
- Bug #1678647: write a newline after printing an exception in any
|
|
case, even when converting the value to a string failed.
|
|
|
|
- The dir() function has been extended to call the __dir__() method on
|
|
its argument, if it exists. If not, it will work like before. This
|
|
allows customizing the output of dir() in the presence of a
|
|
__getattr__().
|
|
|
|
- Patch #922167: Python no longer segfaults when faced with infinitely
|
|
self-recursive reload() calls (as reported by bug #742342).
|
|
|
|
- Patch #1675981: remove unreachable code from ``type.__new__()``
|
|
method.
|
|
|
|
- Patch #1491866: change the complex() constructor to allow
|
|
parthensized forms. This means complex(repr(x)) now works instead of
|
|
raising a ValueError.
|
|
|
|
- Patch #703779: unset __file__ in __main__ after running a file. This
|
|
makes the filenames the warning module prints much more sensible
|
|
when a PYTHONSTARTUP file is used.
|
|
|
|
- Variant of patch #697613: don't exit the interpreter on a SystemExit
|
|
exception if the -i command line option or PYTHONINSPECT environment
|
|
variable is given, but break into the interactive interpreter just
|
|
like on other exceptions or normal program exit.
|
|
|
|
- Patch #1638879: don't accept strings with embedded NUL bytes in
|
|
long().
|
|
|
|
- Bug #1674503: close the file opened by execfile() in an error
|
|
condition.
|
|
|
|
- Patch #1674228: when assigning a slice (old-style), check for the
|
|
sq_ass_slice instead of the sq_slice slot.
|
|
|
|
- When printing an unraisable error, don't print exceptions. before
|
|
the name. This duplicates the behavior whening normally printing
|
|
exceptions.
|
|
|
|
- Bug #1653736: Properly discard third argument to
|
|
slot_nb_inplace_power.
|
|
|
|
- PEP 352: Raising a string exception now triggers a TypeError.
|
|
Attempting to catch a string exception raises DeprecationWarning.
|
|
|
|
- Bug #1377858: Fix the segfaulting of the interpreter when an object
|
|
created a weakref on itself during a __del__ call for new-style
|
|
classes (classic classes still have the bug).
|
|
|
|
- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
|
|
frame's thread state.
|
|
|
|
- patch #1630975: Fix crash when replacing sys.stdout in
|
|
sitecustomize.py.
|
|
|
|
- Prevent seg fault on shutdown which could occur if an object raised
|
|
a warning.
|
|
|
|
- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to
|
|
avoid relying on atexit.
|
|
|
|
- Bug #1590891: random.randrange don't return correct value for big
|
|
number.
|
|
|
|
- Patch #1586791: Better exception messages for some operations on
|
|
strings, tuples and lists.
|
|
|
|
- Bug #1067760: Deprecate passing floats to file.seek.
|
|
|
|
- Bug #1591996: Correctly forward exception in instance_contains().
|
|
|
|
- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
|
|
|
|
- Bug #1576657: when setting a KeyError for a tuple key, make sure
|
|
that the tuple isn't used as the "exception arguments tuple".
|
|
|
|
- Bug #1565514: SystemError not raised on too many nested blocks.
|
|
|
|
- Bug #1576174: WindowsError now displays the windows error code
|
|
again, no longer the posix error code.
|
|
|
|
- Patch #1549049: Support long values in structmember, issue warnings
|
|
if the assigned value for structmember fields gets truncated.
|
|
|
|
- Update the peephole optimizer to remove more dead code (jumps after
|
|
returns) and inline unconditional jumps to returns.
|
|
|
|
- Bug #1545497: when given an explicit base, int() did ignore NULs
|
|
embedded in the string to convert.
|
|
|
|
- Bug #1569998: break inside a try statement (outside a loop) is now
|
|
recognized and rejected.
|
|
|
|
- list.pop(x) accepts any object x following the __index__ protocol.
|
|
|
|
- A number of places, including integer negation and absolute value,
|
|
were fixed to not rely on undefined behaviour of the C compiler
|
|
anymore.
|
|
|
|
- Bug #1566800: make sure that EnvironmentError can be called with any
|
|
number of arguments, as was the case in Python 2.4.
|
|
|
|
- Patch #1567691: super() and new.instancemethod() now don't accept
|
|
keyword arguments any more (previously they accepted them, but
|
|
didn't use them).
|
|
|
|
- Fix a bug in the parser's future statement handling that led to
|
|
"with" not being recognized as a keyword after, e.g., this
|
|
statement: from __future__ import division, with_statement
|
|
|
|
- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
|
|
|
|
- Fix %zd string formatting on Mac OS X so it prints negative numbers.
|
|
|
|
- Allow exception instances to be directly sliced again.
|
|
|
|
- Bug #1551432: Exceptions do not define an explicit __unicode__
|
|
method. This allows calling unicode() on exceptions classes
|
|
directly to succeed.
|
|
|
|
- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
|
|
Also make sure that every exception class has __module__ set to
|
|
'exceptions'.
|
|
|
|
- Bug #1550983: emit better error messages for erroneous relative
|
|
imports (if not in package and if beyond toplevel package).
|
|
|
|
- Overflow checking code in integer division ran afoul of new gcc
|
|
optimizations. Changed to be more standard-conforming.
|
|
|
|
- Patch #1542451: disallow continue anywhere under a finally.
|
|
|
|
- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
|
|
|
|
- The return tuple from str.rpartition(sep) is (tail, sep, head) where
|
|
head is the original string if sep was not found.
|
|
|
|
- Bug #1520864: unpacking singleton tuples in list comprehensions and
|
|
generator expressions (x for x, in ... ) works again. Fixing this
|
|
problem required changing the .pyc magic number. This means that
|
|
.pyc files generated before 2.5c2 will be regenerated.
|
|
|
|
- ``with`` and ``as`` are now keywords.
|
|
|
|
- Bug #1664966: Fix crash in exec if Unicode filename can't be
|
|
decoded.
|
|
|
|
- Issue #1537: Changed GeneratorExit's base class from Exception to
|
|
BaseException.
|
|
|
|
- Issue #1703448: A joined thread could show up in the
|
|
threading.enumerate() list after the join() for a brief period until
|
|
it actually exited.
|
|
|
|

- unittest now verifies more of its assumptions. In particular,
|
|
TestCase and TestSuite subclasses (not instances) are no longer
|
|
accepted in TestSuite.addTest(). This should cause no
|
|
incompatibility since it never made sense with ordinary subclasses
|
|
-- the failure just occurred later, with a more cumbersome
|
|
exception.

|
|
subprocess.

|
|
iso8859_16.
|
|
|
|
- Patch #1638243: the compiler package is now able to correctly

|
|
types instead.

|
|
|

|
|

|
- Fix turtle so that time.sleep is imported for the entire library.

|
|

works as expected. ``mmap.find`` also takes an optional ``end``
|
|
parameter.

|
|
|
- _winreg's HKEY object has gained __enter__ and __exit__ methods to
|
|
support the context manager protocol. The _winreg module also
|
|
gained a new function ``ExpandEnvironmentStrings`` to expand

REG_EXPAND_SZ keys.
|
|
|
|
- itertools.starmap() now accepts any iterable input. Previously, it

|
chain.from_iterable().
|
|

|
|
the behavior into line with that for list.__init__().

|
|

|
|
|
|
- Marshal.dumps() now expects exact type matches for int, long, float,
|
|
complex, tuple, list, dict, set, and frozenset. Formerly, it would
|
|
silently miscode subclasses of those types. Now, it raises a
|
|
ValueError instead.
|

|
|

intended for RECNO databases.
|
|
|
|
- pybsddb.sf.net Bug #477182: Load the database flags at database open
|
|
time so that opening a database previously created with the DB_DUP
|
|
or DB_DUPSORT flag set will keep the proper behavior on subsequent
|
|
opens. Specifically: dictionary assignment to a DB object will
|
|
replace all values for a given key when the database allows
|
|
duplicate values. DB users should use DB.put(k, v) when they want
|
|
to store duplicates; not DB[k] = v.
|
|
|
|
- Add the bsddb.db.DBEnv.lock_id_free method.

behavior of quoting dots if they are the second character of any
|
|
line.

|
|
|
|
- Bug #1588217: don't parse "= " as a soft line break in binascii's

|
|
does.

|
|
|
|
- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
|
|
mode by only placing a timeout on the select() if an input hook has
|
|
been defined. This prevents an interactive Python from waking up 10
|
|
times per second. Patch by Richard Boulton.
|
|
|
|
- fixed a bug with bsddb.DB.stat: the flags and txn keyword arguments
|
|

Tests
|
|
-----
|
|
|
|
- Refactor test_logging to use unittest.
|
|
|
|
- Refactor test_profile and test_cprofile to use the same code to
|
|
profile.
|
|
|
|
- Make test_runpy reentrant by fixing _check_module to clear out any
|
|
module being tested. Was causing an error by __import__ doing a
|
|
reload on the second run and thus suppressing bytecode recreation.
|
|
|
|
- Capture socket connection resets and timeouts in test_socket_ssl and
|
|
test_urllib2net and raise test.test_support.ResourceDenied.
|
|
|
|
- Patch #1559413: Fix test_cmd_line if sys.executable contains a
|
|
space.
|
|
|
|
- Added test.test_support.TransientResource which is a context manager
|
|
to surround calls to resources that are not guaranteed to work even
|
|
if test.test_support.requires says that the resource should exist.
|
|
|
|
- Added a test for slicing of an exception.
|
|
|
|
- Added test.test_support.EnvironmentVarGuard. It's a class that
|
|
provides a context manager so that one can temporarily set or unset
|
|
environment variables.
|
|
|
|
- Added some tests for modulefinder.
|
|
|
|
- Converted test_imp to use unittest.
|
|
|
|
- Fix bsddb test_basics.test06_Transactions to check the version
|
|
number properly.
|
|
|
|
- test.test_support.catch_warning is a new context manager that can be
|
|
used to catch the warnings issued by the warning framework.
|
|
|
|
Tools
|
|
-----
|
|
|
|
- Tools/scripts/reindent.py now creates the backup file using
|
|
shutil.copy to preserve user/group and permissions. Added also a
|
|
--nobackup option to not create the backup if the user is concerned
|
|
regarding this. Check issue #1050828 for more details.
|
|
|
|
- Tools/scripts/win_add2path.py was added. The simple script modifes
|
|
the PATH environment var of the HKCU tree and adds the python bin
|
|
and script directory.
|
|
|
|
- Tools/18n/pygettext.py was added to the list of scripts installed by
|
|
Tools/scripts/setup.py (tracker item 642309).
|
|
|
|
- Added IronPython and Jython support to pybench (part of which was
|
|
patch #1563844).
|
|
|
|
- Made some minor changes to pybench output to allow the user to see
|
|
which Python version is running pybench.
|
|
|
|
- Added support for the new platform module feature
|
|
platform.python_implementation(); this will now be saved in the
|
|
benchmark pickle.

Build
|
|
-----
|
|
|
|
- Have the search path for building extensions follow the declared
|
|
order in $CPPFLAGS and $LDFLAGS when adding directories from those
|
|
environment variables.
|
|
|
|
- Bug #1983: Added a check to pyport to verify that sizeof(pid_t) is
|
|
smaller or equal sizeof(long).
|
|
|
|
- Bug #1234: Fixed semaphore errors on AIX 5.2
|
|
|
|
- Issue #1726: Remove Python/atof.c from PCBuild/pythoncore.vcproj.
|
|
|
|
- Removed PCbuild8/ directory and added a new build directory for VS
|
|
2005 based on the VS 2008 build directory to PC/VS8.0. The script
|
|
PCbuild/vs8to9.py was added to sync changes from PCbuild to
|
|
PC/VS8.0.
|
|
|
|
- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed
|
|
PCBuild9/ directory to PCBuild/.
|
|
|
|
- Bug #1699: Define _BSD_SOURCE only on OpenBSD.
|
|
|
|
- Bug #1608: use -fwrapv when GCC supports it. This is important,
|
|
newer GCC versions may optimize away overflow buffer overflow checks
|
|
without this option!
|
|
|
|
- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
|
|
|
|
- Add a FAST_LOOPS build option that speeds-up looping by trading away
|
|
periodic threadstate and signal checking in tight loops. By
|
|
default, this option is turned-off. It should only be enabled in
|
|
debugged, performance critical applications.
|
|
|
|
- Patch #786737: Allow building in a tree of symlinks pointing to a
|
|
readonly source.
|
|
|
|
- Bug #1737210: Change Manufacturer of Windows installer to PSF.
|
|
|
|
- Bug #1746880: Correctly install DLLs into system32 folder on Win64.
|
|
|
|
- Define _BSD_SOURCE, to get access to POSIX extensions on OpenBSD
|
|
4.1+.
|
|
|
|
- Stop supporting AtheOS and cause a build error in configure for the
|
|
platform.
|
|
|
|
- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
|
|
returned by python-config if Python was built with --enable-shared
|
|
because that prevented the shared library from being used.
|
|
|
|
- Patch #1569798: fix a bug in distutils when building Python from a
|
|
directory within sys.exec_prefix.
|
|

|
|
|
|
- Disable _XOPEN_SOURCE on NetBSD 1.x.
|
|
|
|
- configure now checks whether gcc supports the PyArg_ParseTuple
|
|
format attribute.
|
|
|
|

|
|
Repair so that it's back to how it was in 2.4.3.

|
|
environment.
|
|
|
|
|
|
C API
|
|
-----
|
|
|
|
- Unified naming convention for free lists and their limits. All free
|
|
lists in Object/ are named ``free_list``, the counter ``numfree``
|
|
and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
|
|
#ifndef block.
|
|
|
|
- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
|
|
to ``PyTuple_SetItem``, it can be used to populate a brand new
|
|
frozenset; but it does not steal a reference to the added item.
|
|
|
|
- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
|
|
|
|
- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
|
|
and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
|
|
PyLong_FromSsize_t public functions.
|
|
|
|
- Patch #1720595: add T_BOOL to the range of structmember types.
|
|
|
|
- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
|
|
``PyFloat_GetInfo()`` to the float API.
|
|
|
|
- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
|
|
of w# format code incorrectly truncated the length to an int, even
|
|
when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
|
|
incorrect results with huge strings.
|
|
|
|
- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
|
|
Py_TYPE and Py_REFCNT.
|
|
|
|
- PEP 3123: Provide forward compatibility with Python 3.0, while
|
|
keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
|
|
and PyVarObject_HEAD_INIT.
|
|
|
|
- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
|
|
defined.
|
|
|
|
- Patch #1733960: Allow T_LONGLONG to accept ints.
|
|
|
|
- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
|
|
|
|
- Added a new API function ``PyImport_ImportModuleNoBlock``.
|
|
|
|
- Bug #1637022: Prefix AST symbols with _Py_.
|
|
|
|
- Fix some leftovers from the conversion from int to Py_ssize_t
|
|
(relevant to strings and sequences of more than 2**31 items).
|
|
|
|
- Make _PyGILState_NoteThreadState() static, it was not used anywhere
|
|
outside of pystate.c and should not be necessary.
|
|
|
|
- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
|
|
absolute imports. In earlier versions they might have used relative
|
|
imports under some conditions.
|
|
|
|
- Added case insensitive comparison methods ``PyOS_stricmp(char*,
|
|
char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
|
|
|
|
- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
|
|
macro so it can be used as an expression.
|
|
|
|
|
|
Windows
|
|
-------
|
|
|
|
- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
|
|
requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
|
|
macros are set to Win2k for x86/32bit builds and WinXP for AMD64
|
|
builds.
|
|
|
|
- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
|
|
_CRT_NONSTDC_NO_DEPRECATE.
|
|
|
|
- Bug #1216: Restore support for Visual Studio 2002.
|
|
|
|
|
|
Mac
|
|
---
|
|
|
|
- cfmfile now raises a DeprecationWarning.
|
|
|
|
- buildtools now raises a DeprecationWarning.
|
|
|
|
- Removed the macfs module. It had been deprecated since Python 2.5.
|
|
This lead to the deprecation of macostools.touched() as it relied
|
|
solely on macfs and was a no-op under OS X.
