What's New in Python 2.7 alpha 1
|
|
================================
|
|
|
|
*Release date: XX-XXX-20XX*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- 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 type code and we have an exponent.
|
|
|
|
- Issue #3166: Make long -> float (and int -> float) conversions
|
|
correctly rounded.
|
|
|
|
- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
|
|
some builtin 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 #5704: the "-3" command-line option now implies "-t".
|
|
|
|
- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
|
|
its clarity and its speed.
|
|
|
|
- Issue #2396: the memoryview object was backported from Python 3.1.
|
|
|
|
- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
|
|
when hitting the recursion limit under certain circumstances.
|
|
|
|
- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
|
|
|
|
- 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.)
|
|
|
|
- Issue #4474: PyUnicode_FromWideChar now converts characters outside
|
|
the BMP to 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.
|
|
|
|
- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
|
|
rotating the object pointer by 4 bits to the right.
|
|
|
|
- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
|
|
it now 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
|
|
|
|
- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
|
|
|
|
- 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 #5084: unpickling now interns the attribute names of pickled objects,
|
|
saving memory and avoiding growth in size of subsequent pickles. Proposal
|
|
and original patch by Jake McGuire.
|
|
|
|
- Issue #3002: ``shutil.copyfile()`` and ``shutil.copytree()`` now raise an
|
|
error when a named pipe is encountered, rather than blocking infinitely.

string is already in normalized form, by performing a quick check beforehand.
|
|
Original patch by Rauli Ruohonen.
|
|
|
|
- Issue #5853: calling a function of the mimetypes module from several threads
|
|
at once could hit the recursion limit if the mimetypes database hadn't been
|
|
initialized before.
|
|
|
|
- Issue #5854: Updated __all__ to include some missing names and remove some
|
|
names which should not be exported.

|
|
instances.
|

|
|
that's valid for float() is now valid for Fraction(), with the
|
|
exception of strings representing NaNs and infinities.
|
|
|
|
- Issue #5795: Fixed test_distutils failure on Debian ppc.
|
|
|
|
- Issue #5768: Fixed bug in Unicode output logic and test case for same.
|
|
|
|
- Issue #1161031: fix readwrite select flag handling: POLLPRI now
|
|
results in a handle_expt_event call, not handle_read_event, and POLLERR
|
|
and POLLNVAL now call handle_close, not handle_expt_event. Also,
|
|
dispatcher now has an 'ignore_log_types' attribute for suppressing
|
|
log messages, which is set to 'warning' by default.
|
|
|
|
- Issue #5607: fixed Distutils test_get_platform for Mac OS X fat binaries.

|
|
of the equality operator.
|
|
|
|
- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were added.
|
|
addCleanup allows you to add cleanup functions that will be called
|
|
unconditionally (after setUp if setUp fails, otherwise after tearDown). This
|
|
allows for much simpler resource allocation and deallocation during tests.
|
|
|
|
- Issue #3379: unittest.main now takes an optional exit argument. If False main
|
|
doesn't call sys.exit allowing it to be used from the interactive interpreter.

This defaults to False, but if set to True useful error messages are shown in
|
|
addition to explicit messages passed to assert methods.

instead of performing them in functions. Helps prevent import deadlocking in
|
|
threads.
|
|
|
|

|
|
|
|
- Actually make the SimpleXMLRPCServer CGI handler work.
|
|
|
|
- Issue #2522: locale.format now checks its first argument to ensure it has
|
|
been passed only one pattern, avoiding mysterious errors where it appeared
|
|
that it was failing to do localization.
|
|
|
|
- Issue #5583: Added optional Extensions in Distutils. Initial patch by Georg
|
|
Brandl.
|
|
|
|
- Issue #5619: Multiprocessing children disobey the debug flag and causes

|
|
manager use: "with multiprocessing.Lock()" works now.
|
|
|
|
- Issue #5177: Multiprocessing's SocketListener class now uses
|
|
socket.SO_REUSEADDR on all connections so that the user no longer needs
|
|
to wait 120 seconds for the socket to expire.
|
|
|
|
- Adjusted _tkinter to compile without warnings when WITH_THREAD is not
|
|
defined (part of issue #5035).
|
|
|
|
- Issue #5561: Removed the sys.version_info shortcuts from platform's
|
|
python_version() and python_version_tuple() since they produced different
|
|
output compared to previous Python versions.
|
|
|
|
- Issue #1034053: unittest now supports skipping tests and expected failures.
|
|
|
|
- The unittest.TestCase.assertRaises() method now returns a context manager when
|
|
not given a callable so that code to be tested can be written inline using
|
|
a with statement.
|
|
|
|
- The unittest.TestCase.assertEqual() now displays the differences in lists,
|
|
tuples, dicts and sets on failure. Many new handy type and comparison
|
|
specific assert* methods have been added that fail with error messages
|
|
actually useful for debugging. Contributed in part by Google. [Issue #2578]
|
|
|
|
- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
|
|
forever on incomplete input. That caused tarfile.open() to hang when used
|
|
with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
|
|
partial bzip2 compressed data.
|
|
|
|
- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to
|
|
even if an exception occurs.
|
|
|
|
- Issue #5381: Added object_pairs_hook to the json module. This allows
|
|
OrderedDicts to be built by the decoder.

|
|
specifier to Decimal.__format__

|
|
character.
|
|
|
|

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__.

|
|
|
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 Misc/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.
|
|
|
|

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 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
|

|
|
|
|

|
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.
|
|
|
|
- logging: fixed lack of use of encoding attribute specified on a stream.

|
- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing
|
|
SEM_VALUE_MAX.
|
|
|

|
|
|
|
- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
|
|
|
|
- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
|
|
remaining ones have "pysqlite_" prefix.
|
|
|
|
- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Tests
|
|
-----
|
|
|
|

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
|
|
version that did not raise a DeprecationWarning under -3.
|
|
|
|
- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
|
|
a MemoryError rather than silently stop the iteration.
|
|
|
|
- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
|
|
to _sre.compile() will now be rejected. This should not affect anybody
|
|
since the re.compile() function never generates invalid re-bytecode.
|
|
|
|
- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
|
|
upon first access it can be automatically initialized from the csv file if
|
|
it wasn't initialized during instantiation.
|
|
|
|
- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
|
|
the reload() built-in has been removed.
|
|
|
|
- Changed code in the following modules/packages to remove warnings raised
|
|
while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
|
|
ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
|
|
filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
|
|
pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
|
|
subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
|
|
threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
|
|
|
|
- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
|
|
raised an AttributeError.
|
|
|
|
- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
|
|
asking for a specific length. This problem only affected files opened
|
|
using the new "io" module, not the built-in open() function.
|
|
|
|
- Issue #3449: Update decimal module to use most recent specification
|
|
(v. 1.68) and tests (v. 2.58) from IBM.
|
|
|
|
- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
|
|
|
|
- Issue 1592: Improve error reporting when operations are attempted
|
|
on a closed shelf.
|
|
|
|
- Deprecate the "ast" parser function aliases.
|
|
|
|
- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
|
|
|
|
- Issue #3303: Fix a crash in locale.strcoll() when calling it with
|
|
invalid arguments.
|
|
|
|
- Issue #3302: Fix several crashes when calling locale's gettext functions
|
|
with None arguments.
|
|
|
|
- Issue #3389: Allow resolving dotted names for handlers in logging
|
|
configuration files.
|
|
|
|
- Deprecate the sunaudio module for removal in Python 3.0.
|
|
|
|
- Issue #3394: zipfile.writestr sets external attributes when passed a
|
|
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
|
|
argument in python 2.5, this broke code that subclassed Popen to include its
|
|
own poll method. Fixed my moving _deadstate to an _internal_poll method.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Generate the PatternGrammar pickle during "make install".
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
- Issue #2235: the C API function PyObject_HashNotImplemented and its
|
|
interaction with the tp_hash slot (added in 2.6b2) are now documented
|
|
|
|
- Issue #643841: The language reference now provides more detailed
|
|
coverage of the lookup process for special methods. The disclaimers
|
|
regarding lack of coverage of new-style classes have also been
|
|
removed, since the coverage is now fairly reasonable.
|
|
|
|
|
|
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

|
|
- 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().
|
|
|

|
|
Zip files with archives by setting the 'comment' attribute of a ZipFile.
|
|
|
|
- Issue #449227: The rlcompleter module now adds "(" to callable objects
|
|
when completed.
|
|
|
|

|
|
redundant ":443" port number designation when the connection is using the

|
- 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
|
|
-----

|
*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().
|
|
|
|
- Several set methods now accept multiple arguments: update(), union(),
|
|
intersection(), intersection_update(), difference(), and difference_update().
|
|
|
|
- Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes.
|
|
|
|
- New environment variable PYTHONIOENCODING.
|
|
|
|

|
|
|

|
|
|
|

|
|
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.

|
|
|
|

|
|
|
|

Build
|
|
-----

- The Windows installer now includes Tk 8.5, bzip2 1.0.5, and SQLite 3.5.9.
|
|
|
|
- Patch #1722225: Support QNX 6.

- On MacOS X it is now possible to install the framework in 64-bit
|
|
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).
|
|
|
|
|
|
C API
|
|
-----
|
|

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

|
|
|
|
- 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.
|
|
|

|
What's New in Python 2.6 alpha 2?
|
|
=================================
|
|
|
|
*Release date: 02-Apr-2008*
|
|
|
|
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
|
|
call threading.currentThread().
|
|
|
|
- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
|
|
cannot be executed.
|
|
|
|
- The compilation of a class nested in another class used to leak one
|
|
reference on the outer class name.
|
|
|
|
- Patch #1810: compile() can now compile _ast trees as returned by
|
|
``compile(..., PyCF_ONLY_AST)``.
|
|
|
|
- Patch #2426: Added sqlite3.Connection.iterdump method to allow easy
|
|
dumping of databases. Contributed by Paul Kippes at PyCon 2008.

|
- Added backport of bytearray type.
|
|
|
|
- Issue #2355: add Py3k warning for buffer().
|
|
|
|
- Issue #1477: With narrow Unicode builds, the unicode escape sequence
|
|
\Uxxxxxxxx did not accept values outside the Basic Multilingual
|
|
Plane. This affected raw unicode literals and the
|
|
'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.
|
|
|
|
- Issue #2346/#2347: add Py3k warnings for __methods__ and
|
|
__members__.

- Issue #2321: use pymalloc for unicode object string data to reduce
|
|
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
|
|
"0b". This also affects int(x, 0).
|
|
|
|
- Issue #2359: Adding deprecation warnings for array.{read,write}.
|
|
|
|
- Issue #1779871: GNU gcc can now build Python on OS X because the

|
- Issue #2179: speed up with statement execution by storing the exit
|
|
method on the stack instead of in a temporary variable (patch by
|
|
Jeffrey Yaskin)
|
|
|
|
- Issue #2238: Some syntax errors in *args and **kwargs expressions
|
|
could give bogus error messages.
|

|
|
- Issue #2317: logging.handlers: TimedRotatingFileHandler now uses
|
|
improved logic for removing old files.
|
|
|
|
- Issue #2495: tokenize.untokenize now inserts a space between two
|
|
consecutive string literals; previously, ["" ""] was rendered as
|
|
[""""], which is incorrect python code.
|
|
|
|
- Issue #2248: return the result of the QUIT command. from
|
|
SMTP.quit().
|
|
|
|
- Backport of Python 3.0's io module.
|
|
|
|
- Issue #2482: Make sure that the coefficient of a Decimal is always
|
|
stored as a str instance, not as a unicode instance. This ensures

that str(Decimal) is always an instance of str.
|
|
|
|
- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
|
|
|
|

|
|
installation which do not have the win32all package installed.
|
|
|
|
- Added support to platform.uname() to also report the machine and
|
|
processor information on Windows XP and later. As a result,
|
|
platform.machine() and platform.processor() will report this
|
|
information as well.
|
|
|
|
- The library implementing the 2to3 conversion, lib2to3, was added to
|
|
the standard distribution.
|
|
|
|
- Issue #1747858: Fix chown to work with large uid's and gid's on
|
|
64-bit platforms.
|
|
|
|
- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
|
|
values on 32-bit vs. 64-bit python interpreters. Both were correct,
|
|
but they now both return a signed integer object for consistency.
|
|
|
|
- Issue #1158: add %f format (fractions of a second represented as
|
|
microseconds) to datetime objects. Understood by both strptime and
|
|
strftime.
|
|
|
|
- Issue #705836: struct.pack(">f", x) now raises OverflowError on all
|
|
platforms when x is too large to fit into an IEEE 754 float;
|
|
previously it only raised OverflowError on non IEEE 754 platforms.
|
|
|
|
- Issues #2166, #1741 and #1531505: now distutils deals with HOME
|
|
correctly under win32
|
|
|
|
- Patch #1858: distutils: added multiple server support in .pypirc
|
|
|
|
- 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.
|
|
|
|
- Issue #2220: handle rlcompleter attribute match failure more
|
|
gracefully.
|

|
|
successfully.
|
|
|
|

|
|
- 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 builtin 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() builtin 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 builtin 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.
|
|
|
|
|
|

|
|
now be overridden.

|
|
- Removed uses of dict.has_key() from distutils, and uses of
|
|
callable() from copy_reg.py, so the interpreter now starts up
|
|
without warnings when '-3' is given. More work like this needs to
|
|
be done in the rest of the stdlib.
|
|
|
|

|
|
to fractions.Fraction, to avoid the name clash with the abstract
|
|
base class numbers.Rational. See discussion in issue #1682.

|
statement after the first iteration. Now it correctly steps on the
|
|
expression, and breakpoints on the "while" statement are honored on
|
|
each loop.
|
|
|
|
- Issue #1765140: add an optional delay argument to FileHandler and
|
|
its subclasses. Defaults to false (existing behaviour), but if true,

|
|
and trailing whitespace when constructing from a string.

- mimify now raises a DeprecationWarning upon import.
|
|
|
|

|
the traceback inadvertently or maliciously closing the comment and
|
|
injecting HTML into the error page.

|
|
- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
|
|
(as opposed to the command line) will now write file names ending in
|
|
".cpp" too.
|
|
|
|
- As specified in RFC 2616, an HTTP response like 2xx indicates that
|
|

|
accepted. Now in these cases no error is raised in urllib (issue
|
|
#1177) and urllib2.
|

|
|
distutils.MSVCCompiler.
|
|
|
|

|
|
(telnetlib, ftplib, smtplib and poplib). This is second part of the

|
|
closes patch #723312.
|
|
|
|
- Patch #1676823: Added create_connection() to socket.py, which may be
|
|
called with a timeout, and use it from httplib (whose HTTPConnection

|
- Patch #1630118: add a SpooledTemporaryFile class to tempfile.py.
|
|
|
|

|
|

|
|

|
- Patch #1533909: the timeit module now accepts callables in addition
|
|
to strings for the code to time and the setup code. Also added two
|
|

|
|
methods.
|
|

|
trap the IndexError caused by passing in an invalid breakpoint
|
|
number.

equal to calling getsockname() on the server's socket. Fixed by
|
|
patch #1545011.
|
|
|
|
- Patch #742598: Add .timeout attribute to SocketServer that calls
|
|
.handle_timeout() when no requests are received.

|
|
Python would crash instead of raising an error.

|
- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
|
|
|
|
- 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.
|
|
|
|
- Patch #787789: allow to pass custom TestRunner instances to
|
|
unittest's main() function.

|
|
in HTMLParser.
|

|
|
and allow appending to empty files.

|
|
subprocess.

|
|
iso8859_16.
|
|
|
|
- Patch #1638243: the compiler package is now able to correctly
|
|
compile a with statement; previously, executing code containing a

|
|
|

|
|

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
|
|
required the function inputs to be tuples.

|
|
|
- itertools.chain() now has an alternate constructor,
|
|
chain.from_iterable().
|
|
|
|
- Issue #1646: Make socket support TIPC. The socket module now has

|
|
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.
|

|
|

|
|
fails.
|
|
|
|
- Speed up function calls into the math module.
|
|
|
|
- Bug #1588217: don't parse "= " as a soft line break in binascii's
|

a2b_qp() function, instead leave it in the string as quopri.decode()
|
|
does.
|
|

|
|
|
- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
|
|

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.
|
|
|
|

|
|
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

|
|
|
|
- Converted test_imp to use unittest.

|
|
|
|
Tools
|
|
-----
|
|
|
|

|
|
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.
|
|
|
|
- Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86.
|
|
|
|
- Disable _XOPEN_SOURCE on NetBSD 1.x.
|
|
|
|
- configure now checks whether gcc supports the PyArg_ParseTuple
|
|
format attribute.
|
|
|
|
- Bug #1578513: Cross compilation was broken by a change to configure.
|
|
Repair so that it's back to how it was in 2.4.3.
|
|
|
|
- Patch #1576954: Update VC6 build directory; remove redundant files

|
|
|
|
- Makefile.pre.in(buildbottest): Run an optional script
|
|
pybuildbot.identify to include some information about the build
|
|
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.
