What's New in Python 2.6 beta 2?
|
|
================================
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- 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).

What's New in Python 2.6 beta 1?
|
|
================================
|
|
|
|
*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.
|
|
|
|
- Patch #2488: Add sys.maxsize.
|
|
|
|
- Issue #2353: file.xreadlines() now emits a Py3k warning.
|
|
|
|
- Issue #2863: generators now have a ``gen.__name__`` attribute that
|
|
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.
|
|
|
|
- Issue #2790: sys.flags was not properly exposing its bytes_warning
|
|
attribute.
|
|
|
|
- Issue #2196: hasattr() now lets exceptions which do not inherit
|
|
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.
|
|
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #3116: marshal.dumps() had quadratic behavior for strings > 32Mb.
|
|
|
|
- Issue #2138: Add factorial() to the math module.
|
|
|
|
- The heapq module does comparisons using LT instead of LE. This
|
|
makes its implementation match that used by list.sort().
|
|
|
|
- Issue #2819: add full-precision summation function to math module,
|
|
based on Hettinger's ASPN Python Cookbook recipe.
|
|
|
|
- Issue #2592: delegate nb_index and the floor/truediv slots in
|
|
weakref.proxy.
|
|
|
|
- Support os.O_ASYNC and fcntl.FASYNC if the constants exist on the
|
|
platform.
|
|
|
|
- Support for Windows 9x has been removed from the winsound module.

|
|
bsddb.db.DBEnv.lock_get and other bsddb.db object constructors
|
|
raised an exception.
|
|
|
|
- Issue #2669: bsddb/__init__.py iteration no longer silently fails when
|
|
the database has changed size during iteration. It now raises a
|
|
RuntimeError in the same manner as a dictionary.
|
|
|
|
- Issue #2870: cmathmodule.c compile error.
|
|
|
|

Build
|
|
-----
|
|
|
|
- The Windows installer now includes Tk 8.5, bzip2 1.0.5, and SQLite 3.5.9.
|
|
|
|
- Patch #1722225: Support QNX 6.
|
|
|
|
- ``Lib/lib-old`` is now added to sys.path.
|
|
|
|
- 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
|
|
-----
|
|
|
|
- Add ``PyType_Modified()`` as a public API to clear the type cache.
|
|
|
|
- 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.
|
|
|
|
|
|
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.

|
|
|
|
- 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
|
|

|
|
contains several helpers and constants for math.
|
|
|
|

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.
|
|
|
|
- Patch #2477: Added from __future__ import unicode_literals.
|
|
|
|
- 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 #2358: Add a Py3k warning on sys.exc_clear() usage.
|
|
|
|
- Issue #2400: Allow relative imports to "import *".
|
|
|
|
- Issue #1745: Backport print function with ``from __future__ import
|
|
print_function``.

|
|
|
- Issue #2332: add new attribute names for instance method objects.
|
|
The two changes are: im_self -> __self__ and im_func -> __func__
|
|
|
|
- Issue #2379: Raise a Py3K warning for __getitem__ or __getslice__ on
|
|
exception instances.
|
|
|
|
- Issue #2371: Add a Py3k warning when catching an exception that
|
|
doesn't derive from BaseException.
|
|
|
|
- Issue #2341: Add a Py3k warning when raising an exception that
|
|
doesn't derive from BaseException.
|
|
|
|
- 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()
|
|
|
|
- Issue #2432: give DictReader the dialect and line_num attributes
|
|
advertised in the docs.

|
|
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.
|
|
|
|
- Issue #2225: py_compile, when executed as a script, now returns a
|
|
non- zero status code if not all files could be compiled
|
|
successfully.
|
|
|
|
- Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the
|
|
root directory, and also exclude .hg, .git, .bzr, and _darcs.
|

- Issue #1872: The struct module typecode for _Bool has been changed
|
|
from 't' to '?'.
|
|
|
|
- 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 #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
|
|
|

|
|
|
- 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).
|

|
|
|

|
|
|
|
- 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.

|
- 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.

|
|
each loop.
|
|
|
|
- Issue #1765140: add an optional delay argument to FileHandler and

|
|
and named arguments are passed to a Structure or Union initializer.
|
|
When too many positional arguments are passed, also a TypeError is
|

- Convert the internal ctypes array type cache to a WeakValueDict so
|
|
that array types do not live longer than needed.

|
|
and when creating a recursive instance.
|

|
cannot be loaded in Python 2.5.
|

- 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
|

|
|
-- the failure just occurred later, with a more cumbersome
|
|
exception.

longer than 3 bytes.
|
|
|
|
- The implementation of UnicodeError objects has been simplified
|
|
(start and end attributes are now stored directly as Py_ssize_t

|
|

|
|
ValueError instead.

|
|
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.
|

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

|
|
profile.
|
|
|

|
|
|
|
- Added a test for slicing of an exception.

|
|
regarding this. Check issue 1050828 for more details.
|

|
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
|
|
in VC7.
|
|
|
|
- Bug #1568842: Fix test for uintptr_t.
|
|
|
|
- Patch #1540470: for OpenBSD 4.0.
|
|
|
|
- Fix build failure on kfreebsd and on the hurd.
|
|
|
|
- Fix the build of the library reference in info format.
|
|
|
|
- Allow Emacs 22 for building the documentation in info format.
|
|
|
|
- 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.
