Ned Deily657b2de2011-06-28 19:51:30 -0700753- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
754 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
755 interpreter process. This could cause failures in non-Distutils subprocesses
756 and was unreliable since tests or user programs could modify the interpreter
757 environment after Distutils set it. Instead, have Distutils set the the
758 deployment target only in the environment of each build subprocess. It is
759 still possible to globally override the default by setting
760 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
761 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700762 was built. Also, implement the same handling in packaging.

3008-----------------
3009
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00003010- Issue #10068: Global objects which have reference cycles with their module's
3011 dict are now cleared again. This causes issue #7140 to appear again.
3012
Victor Stinner257d38f2010-10-09 10:12:11 +00003013- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00003014 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00003015
Georg Brandl27a28582010-10-10 09:49:21 +00003016- ast.literal_eval() can now handle negative numbers. It is also a little more
3017 liberal in what it accepts without compromising the safety of the evaluation.
3018 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00003019
Benjamin Peterson970d1882010-10-02 17:55:47 +00003020- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
3021 result metaclasses can now be ABCs (see #9533).
3022
Victor Stinneraef57e32010-10-02 11:50:49 +00003023- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
3024
Victor Stinner5593d8a2010-10-02 11:11:27 +00003025- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00003026 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
3027 32 bits wchar_t (eg. Linux in narrow build).

3033
Brett Cannon5305a992010-09-27 21:08:38 +00003034- Issue #7397: Mention that importlib.import_module() is probably what someone
3035 really wants to be using in __import__'s docstring.
3036
Georg Brandl27a28582010-10-10 09:49:21 +00003037- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
3038 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00003039
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003040- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003041 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003042
Brian Curtine8e4b3b2010-09-23 20:04:14 +00003043- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
3044
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003045- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3046 threads are still running. Instead, reinitialize the GIL on a second call to
3047 Py_Initialize().
3048
Georg Brandl27a28582010-10-10 09:49:21 +00003049- All SyntaxErrors now have a column offset and therefore a caret when the error
3050 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003051
Brett Cannonbc2eff32010-09-19 21:39:02 +00003052- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3053 module that was imported, but instead gets the module from sys.modules.
3054
Nick Coghlan37ee8502010-12-03 14:26:13 +00003055- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003056 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00003057
Georg Brandl27a28582010-10-10 09:49:21 +00003058- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3059 with a non-empty format string. This is an effort to future-proof user
3060 code. If a derived class does not currently implement __format__ but later
3061 adds its own __format__, it would most likely break user code that had
3062 supplied a format string. This will be changed to a DeprecationWaring in
3063 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003064
Antoine Pitrou1df15362010-09-13 14:16:46 +00003065- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3066 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3067 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3068
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003069- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3070 functions from the libc caused the methods .upper() and lower() to become
3071 locale aware and created subtly wrong results.
3072
Georg Brandl27a28582010-10-10 09:49:21 +00003073- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3074 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003075
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003076- Issue #4617: Previously it was illegal to delete a name from the local
3077 namespace if it occurs as a free variable in a nested block. This limitation
3078 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3079
Georg Brandl27a28582010-10-10 09:49:21 +00003080- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3081 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3082 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3083 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003084
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003085- Issue #9757: memoryview objects get a release() method to release the
3086 underlying buffer (previously this was only done when deallocating the
3087 memoryview), and gain support for the context management protocol.
3088
Antoine Pitrou079ce542010-09-08 12:37:10 +00003089- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3090 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00003106- Issue #4661: email can now parse bytes input and generate either converted
3107 7bit output or bytes output. Email version bumped to 5.1.0.
3108
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003109- Issue #1589: Add ssl.match_hostname(), to help implement server identity
3110 verification for higher-level protocols.
3111
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00003112- Issue #9759: GzipFile now raises ValueError when an operation is attempted
3113 after the file is closed. Patch by Jeffrey Finkelstein.
3114
Éric Araujo6108bf52010-10-04 23:52:37 +00003115- Issue #9042: Fix interaction of custom translation classes and caching in
3116 gettext.
3117
Éric Araujoef777bd2010-10-05 00:04:20 +00003118- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003119 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003120 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003121 replacement for old handle_accept() and avoids the user to call accept()
3122 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00003124- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003145- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003146 retry the select() loop instead of bailing out. This is because select() can
3147 incorrectly report a socket as ready for reading (for example, if it received
3148 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00003205- Issue #9854: The default read() implementation in io.RawIOBase now handles
3206 non-blocking readinto() returning None correctly.

Georg Brandl27a28582010-10-10 09:49:21 +00003208- Issue #1552: socket.socketpair() now returns regular socket.socket objects
3209 supporting the whole socket API (rather than the "raw" _socket.socket
3210 objects).

Éric Araujod8c73c62011-03-21 03:15:22 +01003215- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00003216 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00003222- Issue #9837: The read() method of ZipExtFile objects (as returned by
3223 ZipFile.open()) could return more bytes than requested.
3224
Georg Brandl27a28582010-10-10 09:49:21 +00003225- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003228- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003229 it possible for the user to create self-referencing ordered dictionaries which
3230 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003231 approach of using weakref proxies so that reference cycles never get created
3232 in the first place.
3233
Victor Stinnercb043522010-09-10 23:49:04 +00003234- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3235 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00003236 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00003237
Georg Brandl27a28582010-10-10 09:49:21 +00003238- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3239 environment variable to set the filesystem encoding at Python startup.
3240 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3241 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003242
Georg Brandl27a28582010-10-10 09:49:21 +00003243- Issue #9410: Various optimizations to the pickle module, leading to speedups
3244 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
3245 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00003246
Georg Brandl27a28582010-10-10 09:49:21 +00003247- The pprint module now supports printing OrderedDicts in their given order
3248 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00003250- Logging: Added QueueHandler class to facilitate logging usage with
3251 multiprocessing.
3252
Georg Brandl27a28582010-10-10 09:49:21 +00003253- Issue #9707: Rewritten reference implementation of threading.local which is
3254 friendlier towards reference cycles. This change is not normally visible
3255 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003256
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003257- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3258 still return the id of the parent process after it has exited. This process
3259 id may even have been reused by another unrelated process.
3260
Georg Brandl27a28582010-10-10 09:49:21 +00003261- Issue #9792: In case of connection failure, socket.create_connection() would
3262 swallow the exception and raise a new one, making it impossible to fetch the
3263 original errno, or to filter timeout errors. Now the original error is
3264 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003266- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3267 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3268 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003270- Updates to the random module:
3271
Georg Brandl27a28582010-10-10 09:49:21 +00003272 * Document which parts of the module are guaranteed to stay the same across
3273 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003274
Georg Brandl27a28582010-10-10 09:49:21 +00003275 * Update the seed() method to use all of the bits in a string instead of just
3276 the hash value. This makes better use of the seed value and assures the
3277 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003278
Georg Brandl27a28582010-10-10 09:49:21 +00003279 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3280 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3281 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003282
3283 * Improved documentation of arguments to randrange(). Issue #9379.

3289 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3290 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003302- hashlib has two new constant attributes: algorithms_guaranteed and
3303 algorithms_avaiable that respectively list the names of hash algorithms
3304 guaranteed to exist in all Python implementations and the names of hash
3305 algorithms available in the current process.
3306

Georg Brandl649971e2010-09-05 17:06:50 +00003397- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3398 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
3399 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00003410- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3411 now removed, since their effect was inexistent in 3.x (the default encoding is
3412 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003413

3416
Georg Brandl649971e2010-09-05 17:06:50 +00003417- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3418 platforms. Previously, it inlined only when using Microsoft Visual C.

Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00003433- Issue #5127: The C functions that access the Unicode Database now accept and
3434 return characters from the full Unicode range, even on narrow unicode builds
3435 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3436 in Python is that unicodedata.numeric() now returns the correct value for
3437 large code points, and repr() may consider more characters as printable.
3438
Victor Stinner6c00c142010-08-17 23:37:11 +00003439- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
3440 as a unicode object, instead of a byte string. Function needed to support
3441 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3442 function.
3443
Victor Stinner6961bd62010-08-17 22:26:51 +00003444- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

Georg Brandl649971e2010-09-05 17:06:50 +00003448- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for

Ezio Melotti57221d02010-07-01 07:32:02 +00003817- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003818 start byte and the continuation byte(s) are now considered invalid, instead of
3819 the number of bytes specified by the start byte. E.g.:
3820 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3821 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3822 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3823 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003853- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003854 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003866- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3867 TypeError instead of giving a DeprecationWarning when a float is parsed using
3868 the 'L' code (for long long). (All other integer codes already raise
3869 TypeError in this case.)

3873 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3874
Georg Brandl62069d32010-07-31 08:56:11 +00003875- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3876 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003877
3878- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003879 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003880 like bytearray.
3881
Georg Brandl62069d32010-07-31 08:56:11 +00003882- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003883 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003890- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3891 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3892 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3893 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003895- Issue #8748: Fix two issues with comparisons between complex and integer
3896 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003897 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3898 (2) The comparison raised an OverflowError for large integers, leading to
3899 unpredictable exceptions when combining integers and complex objects in sets
3900 or dicts.

4204 `va_copy`, but available on all python platforms.
4205
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004206- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4207 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

4230 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4231 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004232 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004242- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4243 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4244 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4261 gives improved memory leak detection when running under Valgrind, while taking
4262 advantage of pymalloc at other times.

4338 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004339 applications that use a lot of regular expressions and limits the impact of
4340 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004594- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4595 operation raises multiple signals and more than one of those signals is
4596 trapped, the specification determines the order in which the signals should be
4597 handled. In many cases this order wasn't being followed, leading to the wrong
4598 Python exception being raised.

4755 return a result based on the numeric values of the operands; previously they

4819 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004821- subprocess.Popen now has restore_signals and start_new_session features. The
4822 default of restore_signals=True is a new behavior compared to earlier Python
4823 versions. This means that signals such as SIGPIPE are not ignored by default
4824 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005317- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005318 compared to other unix systems. In particular, os.getgroups() does not reflect
5319 any changes made using os.setgroups() but basicly always returns the same
5320 information as the id command. os.getgroups() can now return more than 16
5321 groups on MacOSX.

5347 Prior to this change, timezone adjustment in utctimetuple() could produce
5348 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5352 directive. When the ``%z`` directive is present in the format string, an
5353 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5354 ``datetime.timezone`` instance constructed from the parsed offset. If both
5355 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5356 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005358- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005359 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5360 ``datetime.timezone``, return fixed name and UTC offset from their
5361 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5362 returns ``None``. A class attribute, ``utc`` contains an instance
5363 representing the UTC timezone. Original patch by Rafe Kaplan.

5380 with an improved 'binary-split' algorithm that uses fewer multiplications and
5381 allows many of the multiplications to be performed using plain C integer
5382 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005388- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5389 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005390 the result is now always correctly rounded, and is equivalent to ``td /
5391 timedelta(seconds=1)``.

5400 integer format code, struct.pack first attempts to convert the non-integer
5401 using its __index__ method. If that method is non-existent or raises
5402 TypeError it goes on to try the __int__ method, as described below.

5784
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005785- Issue #6137: The pickle module now translates module names when loading
5786 or dumping pickles with a 2.x-compatible protocol, in order to make data
5787 sharing and migration easier. This behaviour can be disabled using the
5788 new `fix_imports` optional argument.

5843 that would raise SystemError.
5844
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005845- Issue #5982: staticmethod and classmethod now expose the wrapped
5846 function with __func__.
5847
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005848- Added support for multiple context managers in the same with-statement.
5849 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005851- Issue #5829: complex("1e500") no longer raises OverflowError. This
5852 makes it consistent with float("1e500") and interpretation of real
5853 and imaginary literals.
5854
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005855- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005859- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5860 (1) inf and nan strings with trailing whitespace were incorrectly
5861 rejected; (2) parsing of strings representing infinities and nans
5862 was locale aware; and (3) the interpretation of fromhex('-nan')
5863 didn't match that of float('-nan').

5874
Georg Brandlfaf41492009-05-26 18:31:11 +00005875- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors

5879 names: cls, self, tuple, itemgetter, and property.
5880
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005881- In unittest, using a skipping decorator on a class is now equivalent to
5882 skipping every test on the class. The ClassTestSuite class has been removed.
5883
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005884- Issue #6050: Don't fail extracting a directory from a zipfile if
5885 the directory already exists.
5886
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005887- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5888 than an int, which makes some operations possible under 64-bit Linux (e.g.
5889 DN_MULTISHOT with F_NOTIFY).
5890
Antoine Pitrou716c4442009-05-23 19:04:03 +00005891- Issue #5761: Add the name of the underlying file to the repr() of various
5892 IO objects.
5893
R. David Murraycaa27b72009-05-23 18:49:56 +00005894- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5895 by Musashi Tamura, tests by Marcin Bachry.
5896
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005897- Issue #1983: Fix functions taking or returning a process identifier to use
5898 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5899 a process identifier type wider than the standard C integer type.
5900
R. David Murray87e20742009-05-23 01:30:26 +00005901- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +00005911- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
5912
Antoine Pitroue4501852009-05-14 18:55:55 +00005913- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5914 library. This means, for example, that opening an UTF-16 text file in
5915 append mode doesn't add a BOM at the end of the file if the file isn't
5916 empty.
5917
R. David Murray74b89242009-05-13 17:33:03 +00005918- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5919 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5920 corrects a pydoc regression.
5921
Georg Brandl5f90d792010-08-01 22:31:05 +00005922- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005923 now it does. This also means getfp method now returns the real fp.

5926------------
5927
5928- Issue #6047: fullinstall has been removed because Python 3's executable will
5929 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00005930
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00005931- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00005955- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005956 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005961What's New in Python 3.1 beta 1?
5962================================
5963
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005964*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005965
5966Core and Builtins
5967-----------------
5968
Mark Dickinson865e01a2009-05-07 16:37:01 +00005969- Issue #5914: Add new C API function PyOS_string_to_double, and
5970 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5971
Eric Smith741191f2009-05-06 13:08:15 +00005972- Issue #3382: float.__format__, complex.__format__, and %-formatting
5973 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5974 affects nan -> NAN and inf -> INF.
5975
Mark Hammond5a607a32009-05-06 08:04:54 +00005976- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5977 in all operations, including splitdrive, split, etc. splitunc() now issues
5978 a PendingDeprecation warning.
5979
Eric Smith63376222009-05-05 14:04:18 +00005980- Issue #5920: For float.__format__, change the behavior with the
5981 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5982 to be like 'g' but with at least one decimal point and with a
5983 default precision of 12. Previously, the behavior the same but with
5984 a default precision of 6. This more closely matches str(), and
5985 reduces surprises when adding alignment flags to the empty
5986 presentation type. This also affects the new complex.__format__ in
5987 the same way.
5988
Martin v. Löwis011e8422009-05-05 04:43:17 +00005989- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5990
R. David Murrayb18500d2009-05-04 22:59:07 +00005991- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5992 shadowed by classtype's, even if it was None. property now
5993 inserts the __doc__ into the subclass instance __dict__.
5994
Antoine Pitrou244651a2009-05-04 18:56:13 +00005995- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5996 sequences. Patch by Nick Barnes and Victor Stinner.
5997
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005998- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005999
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006000- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6001 received a new method, detach(). detach() disconnects the underlying stream
6002 from the buffer or text IO and returns it.
6003
Mark Dickinson33841c32009-05-01 15:37:04 +00006004- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6005 floats with absolute value over 1e50. Also remove length
6006 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6007 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006008
Eric Smith741191f2009-05-06 13:08:15 +00006009- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006010 format(complex(1, 2./3), '.5') now produces a sensible result.
6011
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006012- Issue #5864: Fix empty format code formatting for floats so that it
6013 never gives more than the requested number of significant digits.
6014
Eric Smith6dc46f52009-04-27 20:39:49 +00006015- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6016 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6017
Eric Smithcc32a112009-04-26 21:35:14 +00006018- Issue #5835: Deprecate PyOS_ascii_formatd.
6019
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006020- Issue #4971: Fix titlecase for characters that are their own
6021 titlecase, but not their own uppercase.
6022
Benjamin Peterson193152c2009-04-25 01:08:45 +00006023- Issue #5283: Setting __class__ in __del__ caused a segfault.
6024
Mark Dickinsonad476da2009-04-23 19:14:16 +00006025- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6026 z involves nans, infs or negative zeros.
6027
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006028- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006029
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006030- Issue #1869 (and many duplicates): make round(x, n) correctly
6031 rounded for a float x, by using the decimal <-> binary conversions
6032 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6033 consistently agrees with format(x, '.2f').
6034
Benjamin Petersonae937c02009-04-18 20:54:08 +00006035- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6036 some builtin types.
6037
Eric Smith0923d1d2009-04-16 20:16:10 +00006038- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6039
Eric Smith35e84722009-04-16 20:21:28 +00006040- Issue #5515: str.format() type 'n' combined with commas and leading
6041 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006042
6043- Implement PEP 378, Format Specifier for Thousands Separator, for
6044 floats.
6045
Mark Dickinson3370cce2009-04-17 22:40:53 +00006046- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006047 1e11, not 1e12. This avoids printing 13 significant digits in
6048 situations where only 12 of them are correct. Example problem
6049 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6050 long time.)
6051
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006052- Issue #1580: On most platforms, use a 'short' float repr: for a
6053 finite float x, repr(x) now outputs a string based on the shortest
6054 sequence of decimal digits that rounds to x. Previous behaviour was
6055 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006056 Another minor difference is that the new repr switches to
6057 exponential notation at 1e16 instead of the previous 1e17; this
6058 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006059
6060 There's a new sys attribute sys.float_repr_style, which takes
6061 the value 'short' to indicate that we're using short float repr,
6062 and 'legacy' if the short float repr isn't available for one
6063 reason or another.

6065 The float repr change involves incorporating David Gay's 'perfect
6066 rounding' code into the Python core (it's in Python/dtoa.c). As a
6067 secondary consequence, all string-to-float and float-to-string
6068 conversions (including all float formatting operations) will be
6069 correctly rounded on these platforms.

6075
Georg Brandlabc38772009-04-12 15:51:51 +00006076- The string.maketrans() function is deprecated; there is a new static method
6077 maketrans() on the bytes and bytearray classes. This removes confusion about
6078 the types string.maketrans() is supposed to work with, and mirrors the
6079 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006373- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6374 it now forces its argument to double before testing for infinity.
6375
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006376- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +00006386- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006387 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00006389- Issue #4707: round(x, n) now returns an integer if x is an integer.
6390 Previously it returned a float.
6391
Antoine Pitroub52ec782009-01-25 16:34:23 +00006392- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6393 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6394 evaluation loop is compiled with a new dispatch mechanism which gives
6395 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00006409
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006410- Issue #4935: The overflow checking code in the expandtabs() method common
6411 to str, bytes and bytearray could be optimized away by the compiler, letting
6412 the interpreter segfault instead of raising an error.
6413
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006414- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6415 __next__ method.
6416
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006417- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

6424
Antoine Pitrouab868312009-01-10 15:40:25 +00006425- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6426 common cases are optimized thanks to a dedicated fast path and a moderate
6427 amount of loop unrolling.
6428
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006429- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6430 collecting the oldest generation) so that allocating lots of objects without
6431 destroying them does not show quadratic performance. Based on a proposal by
6432 Martin von Löwis at
6433 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6434
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006435- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006436 having been closed (for instance, a read() call could return some
6437 previously buffered data). Patch by Dmitry Vasiliev.
6438
Antoine Pitrou05608432009-01-09 18:53:14 +00006439- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6440 flag to work properly. Furthermore, when specifying -u, the text stdout
6441 and stderr streams have line-by-line buffering enabled (the default being
6442 to buffer arbitrary chunks of data).
6443
Raymond Hettinger35631532009-01-09 03:58:09 +00006444- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6445 instead of ints (reducing its size from 4 to 8 times thereby reducing
6446 Python's overall memory).
6447
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006448- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6449 an existing .py counterpart, override the co_filename attributes of all
6450 code objects if the original filename is obsolete (which can happen if the
6451 file has been renamed, moved, or if it is accessed through different paths).
6452 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6453
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006454- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6455 one byte. Also fixes the meaning of len() so that it returns the number of
6456 items, rather than the size in bytes.
6457
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006458- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Georg Brandlccc47b62008-12-28 11:44:14 +00006472- Issue #4759: None is now allowed as the first argument of

6474
Skip Montanaro80072cb2008-12-23 03:51:14 +00006475- Added test case to ensure attempts to read from a file opened for writing

6491 failures on OS X.
6492
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006493- Issue #4597: Fixed several opcodes that weren't always propagating

6498
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006499- Issue #4445: Replace "sizeof(PyBytesObject)" with
6500 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6501 bytes instances. On a typical machine this saves 3 bytes of memory
6502 (on average) per allocation of a bytes instance.
6503
Christian Heimesa872de52008-12-05 08:26:55 +00006504- Issue #4533: File read operation was dreadfully slow due to a slowly
6505 growing read buffer. Fixed by using the same growth rate algorithm as
6506 Python 2.x.
6507
Antoine Pitrou5504e892008-12-06 21:27:53 +00006508- Issue #4509: Various issues surrounding resize of bytearray objects to

6510
Georg Brandlf9734072008-12-07 15:30:06 +00006511- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6512 method on file objects with closefd=False. The file descriptor is still
6513 kept open but the file object behaves like a closed file. The ``FileIO``
6514 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006523- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6524 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6525 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6526 of using the replace error handler in PyUnicode_DecodeUTF8().
