What's New in Python 3.1 alpha 2?
|
|
=================================
|
|
|
|
*Release date: XXX*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #5126: str.isprintable() returned False for space characters.
|
|
|
|
- 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.int_info structseq to provide information about
|
|
the internal format.
|
|
|
|
- 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 #5392: when a very low recursion limit was set, the interpreter would
|
|
abort with a fatal error after the recursion limit was hit twice.
|
|
|
|
Library
|
|
-------
|
|
|
|
- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
|
|
io.BufferedRandom have been deprecated for removal in Python 3.2.
|
|
|
|
- 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 #2110: Add support for thousands separator and 'n' type
|
|
specifier to Decimal.__format__
|
|
|
|
- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
|
|
'>' alignment characters.
|
|
|
|
- The error detection code in FileIO.close() could fail to reflect the `errno`
|
|
value, and report it as -1 instead.
|
|
|
|
- Issue #5016: FileIO.seekable() could return False if the file position
|
|
was negative when truncated to a C int. Patch by Victor Stinner.
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #5463: In struct module, remove deprecated overflow wrapping
|
|
when packing an integer: struct.pack('=L', -1) now raises
|
|
struct.error instead of returning b'\xff\xff\xff\xff'.
|
|
|
|
|
|
What's New in Python 3.1 alpha 1
|
|
================================
|
|
|
|
*Release date: 2009-03-07*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- The io module has been reimplemented in C for speed.
|
|
|
|
- Give dict views an informative __repr__.
|
|
|
|
- Issue #5247: Improve error message when unknown format codes are
|
|
used when using str.format() with str, int, and float arguments.
|
|
|
|
- Issue #5249: time.strftime returned malformed string when format string
|
|
contained non ascii character on windows.
|
|
|
|
- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
|
|
source has already been decoded into str.
|
|
|
|
- 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 #5137: Make len() correctly raise a TypeError when a __len__ method
|
|
returns a non-number type.
|
|
|
|
- Issue #5182: Removed memoryview.__str__.
|
|
|
|
- Issue #1717: Removed builtin cmp() function, dropped tp_compare
|
|
slot, the C API functions PyObject_Compare and PyUnicode_Compare and
|
|
the type definition cmpfunc. The tp_compare slot has been renamed
|
|
to tp_reserved, and is reserved for future usage.
|
|
|
|
- Issue 1242657: the __len__() and __length_hint__() calls in several tools
|
|
were suppressing all exceptions. These include list() and bytearray().
|
|
|
|
- Issue #4707: round(x, n) now returns an integer if x is an integer.
|
|
Previously it returned a float.
|
|
|
|
- Issue #4753: By enabling a configure option named '--with-computed-gotos'
|
|
on compilers that support it (notably: gcc, SunPro, icc), the bytecode
|
|
evaluation loop is compiled with a new dispatch mechanism which gives
|
|
speedups of up to 20%, depending on the system, on various benchmarks.
|
|
|
|
- Issue #4874: Most builtin decoders now reject unicode input.
|
|
|
|
- Issue #4842: Don't allow trailing 'L' when constructing an integer
|
|
from a string.
|
|
|
|
- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
|
|
|
|
- Issue #4838: When a module is deallocated, free the memory backing the
|
|
optional module state data.
|
|
|
|
- Issue #4910: Rename nb_long slot to nb_reserved, and change its
|
|
type to (void *).
|
|
|
|
- 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 #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
|
|
function no longer attempt to call the __long__ slot to convert an object
|
|
to an integer. Only the __int__ and __trunc__ slots are examined.
|
|
|
|
- Issue #4893: Use NT threading on CE.
|
|
|
|
- Issue #4915: Port sysmodule to Windows CE.
|
|
|
|
- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
|
|
common cases are optimized thanks to a dedicated fast path and a moderate
|
|
amount of loop unrolling.
|
|
|
|
- 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 #4604: Some objects of the I/O library could still be used after
|
|
having been closed (for instance, a read() call could return some
|
|
previously buffered data). Patch by Dmitry Vasiliev.
|
|
|
|
- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
|
|
flag to work properly. Furthermore, when specifying -u, the text stdout
|
|
and stderr streams have line-by-line buffering enabled (the default being
|
|
to buffer arbitrary chunks of data).
|
|
|
|
- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
|
|
instead of ints (reducing its size from 4 to 8 times thereby reducing
|
|
Python's overall memory).
|
|
|
|
- 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 #4580: Fix slicing of memoryviews when the item size is greater than
|
|
one byte. Also fixes the meaning of len() so that it returns the number of
|
|
items, rather than the size in bytes.
|
|
|
|
- Issue #4075: Use OutputDebugStringW in Py_FatalError.
|
|
|
|
- Issue #4747: When the terminal does not use utf-8, executing a script with
|
|
non-ascii characters in its name could fail with a "SyntaxError: None" error.
|
|
|
|
- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
|
|
file with `bytes' 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 #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 #3106: Speedup some comparisons (str/str and int/int).
|
|
|
|
- Issue #2183: Simplify and optimize bytecode for list, dict and set
|
|
comprehensions. Original patch for list comprehensions by Neal Norwitz.
|
|
|
|
- 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.
|
|
|
|
- Issue #2173: When getting device encoding, check that return value of
|
|
nl_langinfo is not the empty string. This was causing silent build
|
|
failures on OS X.
|
|
|
|
- Issue #4597: Fixed several opcodes that weren't always propagating
|
|
exceptions.
|
|
|
|
- Issue #4589: Fixed exception handling when the __exit__ function of a
|
|
context manager returns a value that cannot be converted to a bool.
|
|
|
|
- Issue #4445: Replace "sizeof(PyBytesObject)" with
|
|
"offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
|
|
bytes instances. On a typical machine this saves 3 bytes of memory
|
|
(on average) per allocation of a bytes instance.
|
|
|
|
- Issue #4533: File read operation was dreadfully slow due to a slowly
|
|
growing read buffer. Fixed by using the same growth rate algorithm as
|
|
Python 2.x.
|
|
|
|
- Issue #4509: Various issues surrounding resize of bytearray objects to
|
|
which there are buffer exports (e.g. memoryview instances).
|
|
|
|
- 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 #4569: Interpreter crash when mutating a memoryview with an item size
|
|
larger than 1.
|
|
|
|
- Issue #4748: Lambda generators no longer return a value.
|
|
|
|
- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
|
|
|
|
Library
|

- Issue #1222: locale.format() bug when the thousands separator is a space
|
|
character.
|
|
|
|
- Issue #5472: Fixed distutils.test_util tear down. Original patch by
|
|
Tim Golden.

|
|
|
|
- Issue #2638: Show a window constructed with tkSimpleDialog.Dialog only after
|
|
it is has been populated and properly configured in order to prevent
|
|
window flashing.
|
|
|
|
- Issue #4792: Prevent a segfault in _tkinter by using the
|
|
guaranteed to be safe interp argument given to the PythonCmd in place of
|
|
the Tcl interpreter taken from a PythonCmd_ClientData.
|
|
|
|
- Issue #5193: Guarantee that tkinter.Text.search returns a string.

|
|
with same tagname but larger size than first map. (Windows)
|
|
|
|
- Issue #5386: mmap.write_byte didn't check map size, so it could cause buffer
|
|
overrun.
|
|
|
|
- Issue #1533164: Installed but not listed *.pyo was breaking Distutils
|
|
bdist_rpm command.

|
|
|
|
- Issue #5287: Add exception handling around findCaller() call to help out
|
|
IronPython.
|
|
|
|

|
|
|
|
- Issue #4998: The memory saving effect of __slots__ had been lost on Fractions

|
|
under NT and OS2. Patch by Philip Jenvey.
|
|

|
|
deadlock.
|
|

submodule when a package name is supplied. Initial patch by Andi
|
|
Vajda.
|
|
|
|
- Issue #1731706: Call Tcl_ConditionFinalize for Tcl_Conditions that will

inside its source path if it began with the same letters (e.g. "src" vs.
|
|
"src.new").
|
|
|
|
- Added the ttk module. See issue #2983: Ttk support for Tkinter.
|
|
|
|
- Removed isSequenceType(), isMappingType, and isNumberType() from the
|
|
operator module; use the abstract base classes instead. Also removed
|
|
the repeat() function; use mul() instead.

|
|
been backported to help facilitate transitions from 2.7 to 3.1.

be disabled, and not compiled.
|
|
|
|
- Issue #5008: When a file is opened in append mode with the new IO library,
|
|
do an explicit seek to the end of file (so that e.g. tell() returns the
|
|
file size rather than 0). This is consistent with the behaviour of the
|
|
traditional 2.x file object.
|

|
|
in sharedctypes.py.
|
|
|
|
- Issue #1225107: inspect.isclass() returned True for instances with a custom
|
|
__getattr__.
|
|
|
|
- Issue #3826 and #4791: The socket module now closes the underlying socket
|
|
appropriately when it is being used via socket.makefile() objects
|
|
rather than delaying the close by waiting for garbage collection to do it.
|
|
|
|
- Issue #1696199: Add collections.Counter() for rapid and convenient

|
|
Jacques Frechet.

perform IO operations based on __file__). Original patch by
|
|
Alexander Belopolsky.
|
|
