the encodings package, which would make other tests fail further down
|
|
the road because the internally cached encoders and decoders would point
|
|
to empty global variables.
|
|
|
|
- Issue #7295: Do not use a hardcoded file name in test_tarfile.
|
|
|
|
- Issue #7270: Add some dedicated unit tests for multi-thread synchronization

|
|
tests instead of tempfile.tempdir. This prevents the tests from sharing state
|
|
between concurrent executions on the same system.
|
|
|
|
- Issue #7248: In importlib.test.source.util a try/finally block did not make
|
|
sure that some referenced objects actually were created in the block before
|
|
calling methods on the object.
|
|
|
|
- Issue #7055: test___all__ now greedily detects all modules which have an
|
|
__all__ attribute, rather than using a hardcoded and incomplete list.
|
|
|
|
- Issue #7058: Added save/restore for argv and os.environ to runtest_inner
|
|
in regrtest, with warnings if the called test modifies them.

|
|
|

|
|
|
- Issue #6802: Fix build issues on MacOSX 10.6
|

- collections.namedtuple() was not working with the following field
|
|
names: cls, self, tuple, itemgetter, and property.

|
|
the directory already exists.
|

append mode doesn't add a BOM at the end of the file if the file isn't
|
|
empty.
|
|
|
|
- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

corrects a pydoc regression.
|

What's New in Python 3.1 beta 1?
|
|
================================
|
|
|
|
*Release date: 2009-05-06*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #5914: Add new C API function PyOS_string_to_double, and
|
|
deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
|
|
|
|
- Issue #3382: float.__format__, complex.__format__, and %-formatting
|
|
no longer map 'F' to 'f'. Because of issue #5859 (below), this only
|
|
affects nan -> NAN and inf -> INF.
|
|
|
|
- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
|
|
in all operations, including splitdrive, split, etc. splitunc() now issues
|
|
a PendingDeprecation warning.
|
|
|
|
- Issue #5920: For float.__format__, change the behavior with the
|
|
empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
|
|
to be like 'g' but with at least one decimal point and with a
|
|
default precision of 12. Previously, the behavior the same but with
|
|
a default precision of 6. This more closely matches str(), and
|
|
reduces surprises when adding alignment flags to the empty
|
|
presentation type. This also affects the new complex.__format__ in
|
|
the same way.
|
|
|
|
- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
|
|
|
|
- Issue #5890: in subclasses of 'property' the __doc__ attribute was
|
|
shadowed by classtype's, even if it was None. property now
|
|
inserts the __doc__ into the subclass instance __dict__.
|
|
|
|
- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
|
|
sequences. Patch by Nick Barnes and Victor Stinner.
|
|
|
|
- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
|
|
|
|
- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
|
|
received a new method, detach(). detach() disconnects the underlying stream
|
|
from the buffer or text IO and returns it.
|
|
|
|
- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
|
|
floats with absolute value over 1e50. Also remove length
|
|
restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
|
|
12.34 no longer raise an exception.
|
|
|
|
- Issue #1588: Add complex.__format__. For example,
|
|
format(complex(1, 2./3), '.5') now produces a sensible result.
|
|
|
|
- Issue #5864: Fix empty format code formatting for floats so that it
|
|
never gives more than the requested number of significant digits.
|
|
|
|
- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
|
|
new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
|
|
|
|
- Issue #5835: Deprecate PyOS_ascii_formatd.
|
|
|
|
- Issue #4971: Fix titlecase for characters that are their own
|
|
titlecase, but not their own uppercase.
|
|
|
|
- Issue #5283: Setting __class__ in __del__ caused a segfault.
|
|
|
|
- Issue #5816: complex(repr(z)) now recovers z exactly, even when
|
|
z involves nans, infs or negative zeros.
|
|
|
|
- Issue #3166: Make int -> float conversions correctly rounded.
|
|
|
|
- Issue #1869 (and many duplicates): make round(x, n) correctly
|
|
rounded for a float x, by using the decimal <-> binary conversions
|
|
from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
|
|
consistently agrees with format(x, '.2f').
|
|
|
|
- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
|
|
some builtin types.
|
|
|
|
- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
|
|
|
|
- Issue #5515: str.format() type 'n' combined with commas and leading
|
|
zeros no longer gives odd results with ints and floats.
|
|
|
|
- Implement PEP 378, Format Specifier for Thousands Separator, for
|
|
floats.
|
|
|
|
- The str function switches to exponential notation at
|
|
1e11, not 1e12. This avoids printing 13 significant digits in
|
|
situations where only 12 of them are correct. Example problem
|
|
value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
|
|
long time.)
|
|
|
|
- Issue #1580: On most platforms, use a 'short' float repr: for a
|
|
finite float x, repr(x) now outputs a string based on the shortest
|
|
sequence of decimal digits that rounds to x. Previous behaviour was
|
|
to output 17 significant digits and then strip trailing zeros.
|
|
Another minor difference is that the new repr switches to
|
|
exponential notation at 1e16 instead of the previous 1e17; this
|
|
avoids misleading output in some cases.
|
|
|
|
There's a new sys attribute sys.float_repr_style, which takes
|
|
the value 'short' to indicate that we're using short float repr,
|
|
and 'legacy' if the short float repr isn't available for one
|
|
reason or another.
|
|
|
|
The float repr change involves incorporating David Gay's 'perfect
|
|
rounding' code into the Python core (it's in Python/dtoa.c). As a
|
|
secondary consequence, all string-to-float and float-to-string
|
|
conversions (including all float formatting operations) will be
|
|
correctly rounded on these platforms.
|
|
|
|
See issue 1580 discussions for details of platforms for which
|
|
this change does not apply.
|
|
|
|
- Issue #5759: float() didn't call __float__ on str subclasses.
|
|
|
|
- The string.maketrans() function is deprecated; there is a new static method
|
|
maketrans() on the bytes and bytearray classes. This removes confusion about
|
|
the types string.maketrans() is supposed to work with, and mirrors the
|
|
methods available on the str class.
|
|
|
|
- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
|
|
its clarity and its speed.
|
|
|
|
- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
|
|
to avoid compiler warnings.
|
|
|
|
- Issue #3739: The unicode-internal encoder now reports the number of characters
|
|
consumed like any other encoder (instead of the number of bytes).

What's New in Python 3.1 alpha 2?
|
|
=================================
|
|
|
|
*Release date: 2009-4-4*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Implement PEP 378, Format Specifier for Thousands Separator, for
|
|
integers.
|
|
|
|
- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
|
|
|
|
- Issue #5499: The 'c' code for argument parsing functions now only accepts a
|
|
byte, and the 'C' code only accepts a unicode character.
|
|
|
|
- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
|
|
when hitting the recursion limit under certain circumstances.
|
|
|
|
- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
|
|
|
|
- Fix a segfault when running test_exceptions with coverage, caused by
|
|
insufficient checks in accessors of Exception.__context__.
|
|
|
|
- Issue #5604: non-ASCII characters in module name passed to
|
|
imp.find_module() were converted to UTF-8 while the path is
|
|
converted to the default filesystem encoding, causing nonsense.
|
|
|
|
- Issue #5126: str.isprintable() returned False for space characters.
|
|
|
|
- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
|
|
the end sys.path, for compatibility with the system install of Python.
|
|
|
|
- Issue #4688: Add a heuristic so that tuples and dicts containing only
|
|
untrackable objects are not tracked by the garbage collector. This can
|
|
reduce the size of collections and therefore the garbage collection overhead
|
|
on long-running programs, depending on their particular use of datatypes.
|
|
|
|
- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
|
|
improve its performance. Long divisions and remainder operations
|
|
are now between 50% and 150% faster.
|
|
|
|
- Issue #4258: Make it possible to use base 2**30 instead of base
|
|
2**15 for the internal representation of integers, for performance
|
|
reasons. Base 2**30 is enabled by default on 64-bit machines. Add
|
|
--enable-big-digits option to configure, which overrides the
|
|
default. Add sys.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.
|
|
|
|
- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
|
|
short file names.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #2625: added missing items() call to the for loop in
|
|
mailbox.MH.get_message().
|
|
|
|
- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
|
|
error substitutions from non-strict codec error callbacks in
|
|
incrementalencoder and StreamWriter.
|
|
|
|
- Issue #5656: Fix the coverage reporting when running the test suite with
|
|
the -T argument.
|
|
|
|
- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.
|
|
|
|
- Issue #5624: Fix the _winreg module name still used in several modules.
|
|
|
|
- Issue #5628: Fix io.TextIOWrapper.read() with a unreadable buffer.
|
|
|
|
- Issue #5619: Multiprocessing children disobey the debug flag and causes
|
|
popups on windows buildbots. Patch applied to work around this issue.
|
|
|
|
- Issue #5400: Added patch for multiprocessing on netbsd compilation/support
|
|
|
|
- Issue #5387: Fixed mmap.move crash by integer overflow.
|
|
|
|
- Issue #5261: Patch multiprocessing's semaphore.c to support context
|
|
manager use: "with multiprocessing.Lock()" works now.
|
|
|
|
- Issue #5236: Change time.strptime() to only take strings. Didn't work with
|
|
bytes already but the failure was non-obvious.
|
|
|
|
- Issue #5177: Multiprocessing's SocketListener class now uses
|
|
socket.SO_REUSEADDR on all connections so that the user no longer needs
|
|
to wait 120 seconds for the socket to expire.
|
|
|
|
- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().
|
|
|
|
- Issue #1174606: Calling read() without arguments of an unbounded file
|
|
(typically /dev/zero under Unix) could crash the interpreter.
|
|
|
|
- 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 #5391: mmap now deals exclusively with bytes.
|
|
|
|
- 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'. The
|
|
_PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
|
|
have been removed from the struct module.
|
|
|
|
|
|
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
|

|
|
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.

|
|

|
|
|
- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
|
|
|
|
- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
|
|
PyUnicode_DecodeUTF8() once, remember the result and output it in a second
|
|
step. This avoids problems with counting UTF-8 bytes that ignores the effect
|
|
of using the replace error handler in PyUnicode_DecodeUTF8().

Extension Modules
|
|
-----------------
|
|
|
|
- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
|
|
supporting objects as input no matter how it was compiled (built in
|
|
implementations or external openssl library).
|
|
|
|
- Issue #4397: Fix occasional test_socket failure on OS X.
|
|
|
|
- Issue #4279: Fix build of parsermodule under Cygwin.
|
|
|
|
- Issue #4751: hashlib now releases the GIL when hashing large buffers
|
|
(with a hardwired threshold of 2048 bytes), allowing better parallelization
|
|
on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
|
|
|
|
- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
|
|
|
|
- Issue #4738: Each zlib object now has a separate lock, allowing to compress
|
|
or decompress several streams at once on multi-CPU systems. Also, the GIL
|
|
is now released when computing the CRC of a large buffer. Patch by ebfe.
|
|
|
|

Tests
|
|
-----
|
|
|
|
- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
|
|
Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
|
|
the same behaviour as test_ttkguionly (and now also test_tk) which is to
|
|
skip the tests if DISPLAY is defined but can't be used.
|
|
|
|
- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
|
|
that should cause a test to be skipped are now done using import_module
|
|
from test support, which does the conversion.
|
|
|
|
- Issue #5083: New 'gui' resource for regrtest.
