|
|
|
*Release date: XX-June-2008*
|
|
|
|
Core and Builtins
|

|
-----------------
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #2487: change the semantics of math.ldexp(x, n) when n is too
|
|
large to fit in a C long. ldexp(x, n) now returns a zero (with
|
|
suitable sign) if n is large and negative; previously, it raised
|
|
OverflowError.

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

|
|
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

it only raised OverflowError on non IEEE 754 platforms.
|
|
|
|
- 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

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.
|
|
|
|
- Bug #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.
|
|
|
|
- Bug #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.
|
|
|
|
- Bug #1733488: Fix compilation of bufferobject.c on AIX.
|
|
|
|
- Bug #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.
|
|
|
|
- Bug #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.
|
|
|
|
- Fix Issue #1703448: A joined thread could show up in the
|
|
threading.enumerate() list after the join() for a brief period until
|
|
it actually exited.
|
|

- #1627: httplib now ignores negative Content-Length headers.
|
|
|
|
- #900744: If an invalid chunked-encoding header is sent by a server,

- Issue 1781: ConfigParser now does not let you add the "default" section
|
|
(ignore-case)
|
|
|
|
- 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.
|

|
|
implements the chunked encoding incorrectly.
|
|
|
|
- Rename rational.py to fractions.py and the rational.Rational class
|
|
to fractions.Fraction, to avoid the name clash with the abstract
|
|
base class numbers.Rational. See discussion in issue #1682.
|
|
|
|
- The pickletools module now provides an optimize() function
|
|
that eliminates unused PUT opcodes from a pickle string.

|
|
permissions for missing directories.
|

|
|
after the first iteration. Now it correctly steps on the expression, and
|
|
breakpoints on the "while" statement are honored on each loop.
|
|
|
|
- #1765140: add an optional delay argument to FileHandler and its
|
|
subclasses. Defaults to false (existing behaviour), but if true,
|
|
defers opening the file until the first call to emit().
|
|
|
|
- The pprint module now supports sets and frozensets.
|
|

|
|
(as opposed to the command line) will now write file names ending in

closes patch #723312.
|
|
|
|
- Patch #1676823: Added create_connection() to socket.py, which may be

|
|
- Bug #1681228: the webbrowser module now correctly uses the default
|
|

- The nonobvious commands.getstatus() function is now deprecated.
|
|

for a thing instead of paging it to stdout, which pydoc.doc() does.
|
|
|
|

|
|
|
|
- unittest now verifies more of its assumptions. In particular, TestCase
|

and TestSuite subclasses (not instances) are no longer accepted in
|

|
never made sense with ordinary subclasses -- the failure just occurred
|
|
later, with a more cumbersome exception.

|
|
main() function.

|
|
subprocess.

|
|
iso8859_16.
|
|

|
|
attributes are now stored directly as Py_ssize_t members).
|
|
|
|
- Issue829951: In the smtplib module, SMTP.starttls() now complies with
|
|
RFC 3207 and forgets any knowledge obtained from the server not obtained

|
|
|
|
- Issue1339: The smtplib.SMTP class has been refactored a bit such
|
|
that the SMTP.starttls() caller no longer needs to call ehlo()
|

|
|
of file descriptors without considering errors.
|
|
|
|

|
|
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().
|
|
|
|

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

|
|
get_completion_type to readline.
|
|

|
|
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.
|
|

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

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

|
- Added support for linking the bsddb module against BerkeleyDB 4.5.x
|
|
and 4.6.x.

Tests
|
|
-----
|
|
|
|
- Refactor test_logging to use unittest.
|
|
|
|
- Refactor test_profile and test_cprofile to use the same code to profile.
|
|
|
|
- Make test_runpy reentrant by fixing _check_module to clear out any module
|
|
being tested. Was causing an error by __import__ doing a reload on the
|
|
second run and thus suppressing bytecode recreation.
|
|
|
|
- Capture socket connection resets and timeouts in test_socket_ssl and
|
|
test_urllib2net and raise test.test_support.ResourceDenied.
|
|
|
|
- Patch #1559413: Fix test_cmd_line if sys.executable contains a space.
|
|
|
|
- Added test.test_support.TransientResource which is a context manager to
|
|
surround calls to resources that are not guaranteed to work even if
|
|
test.test_support.requires says that the resource should exist.
|
|
|
|
- Added a test for slicing of an exception.
|
|
|
|

|
|
variables.
|
|
|
|
- Added some tests for modulefinder.
|
|
|
|
- Converted test_imp to use unittest.

- test.test_support.catch_warning is a new context manager that can be used
|
|
to catch the warnings issued by the warning framework.
|
|
|
|
|
|
Tools
|
|
-----
|
|
|
|
- Tools/scripts/reindent.py now creates the backup file using shutil.copy
|
|
to preserve user/group and permissions. Added also a --nobackup option
|
|
to not create the backup if the user is concerned regarding this. Check
|
|
issue 1050828 for more details.
|
|
|
|
- Tools/scripts/win_add2path.py was added. The simple script modifes the
|
|
PATH environment var of the HKCU tree and adds the python bin and script
|
|
directory.
|
|
|
|
- Tools/18n/pygettext.py was added to the list of scripts installed by
|
|
Tools/scripts/setup.py (tracker item 642309).
|
|
|

|
|
to see which Python version is running pybench
|
|
|
|
- Added support for the new platform module feature
|

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 in VC7.

|
|
|

|
|
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.
