Ned Deily657b2de2011-06-28 19:51:30 -070096- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
97 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
98 interpreter process. This could cause failures in non-Distutils subprocesses
99 and was unreliable since tests or user programs could modify the interpreter
100 environment after Distutils set it. Instead, have Distutils set the the
101 deployment target only in the environment of each build subprocess. It is
102 still possible to globally override the default by setting
103 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
104 greater or equal to the default value, the value with which the interpreter
105 was built.

R. David Murray5b2d9dd2011-01-09 02:35:24 +0000944- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +0000945 continuation line in the formatted value has no leading white space and looks
946 like a header. Since Generator uses Header to format all headers, this check
947 is made for all headers in any serialized message at serialization time. This
948 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000949
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000950- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +0200957 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +0000958 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +0000959
Éric Araujof0ab5d62011-05-29 03:43:59 +0200960- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +0000961 rfc2047-encoding header values with embedded newlines, leaving them without
962 folding whitespace. It now uses the continuation_ws, as it does for
963 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000965- Issue #1777412, #10827: Changed the rules for 2-digit years. The
966 time.asctime(), time.ctime() and time.strftime() functions will now format
967 any year when ``time.accept2dyear`` is False and will accept years >= 1000
968 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
969 supported by the OS. With Visual Studio or on Solaris, the year is limited to
970 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001602 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001947- Issue #10068: Global objects which have reference cycles with their module's
1948 dict are now cleared again. This causes issue #7140 to appear again.
1949
Victor Stinner257d38f2010-10-09 10:12:11 +00001950- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001951 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001952
Georg Brandl27a28582010-10-10 09:49:21 +00001953- ast.literal_eval() can now handle negative numbers. It is also a little more
1954 liberal in what it accepts without compromising the safety of the evaluation.
1955 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001956
Benjamin Peterson970d1882010-10-02 17:55:47 +00001957- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1958 result metaclasses can now be ABCs (see #9533).
1959
Victor Stinneraef57e32010-10-02 11:50:49 +00001960- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1961
Victor Stinner5593d8a2010-10-02 11:11:27 +00001962- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001963 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

1973
Georg Brandl27a28582010-10-10 09:49:21 +00001974- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1975 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001977- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001978 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001979
Brian Curtine8e4b3b2010-09-23 20:04:14 +00001980- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1981
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001982- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1983 threads are still running. Instead, reinitialize the GIL on a second call to
1984 Py_Initialize().
1985
Georg Brandl27a28582010-10-10 09:49:21 +00001986- All SyntaxErrors now have a column offset and therefore a caret when the error
1987 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001988
Brett Cannonbc2eff32010-09-19 21:39:02 +00001989- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1990 module that was imported, but instead gets the module from sys.modules.
1991
Nick Coghlan37ee8502010-12-03 14:26:13 +00001992- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001993 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001994
Georg Brandl27a28582010-10-10 09:49:21 +00001995- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1996 with a non-empty format string. This is an effort to future-proof user
1997 code. If a derived class does not currently implement __format__ but later
1998 adds its own __format__, it would most likely break user code that had
1999 supplied a format string. This will be changed to a DeprecationWaring in
2000 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002001
Antoine Pitrou1df15362010-09-13 14:16:46 +00002002- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2003 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2004 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2005
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002006- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2007 functions from the libc caused the methods .upper() and lower() to become
2008 locale aware and created subtly wrong results.
2009
Georg Brandl27a28582010-10-10 09:49:21 +00002010- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2011 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002012
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002013- Issue #4617: Previously it was illegal to delete a name from the local
2014 namespace if it occurs as a free variable in a nested block. This limitation
2015 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2016
Georg Brandl27a28582010-10-10 09:49:21 +00002017- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2018 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2019 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2020 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002021
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002022- Issue #9757: memoryview objects get a release() method to release the
2023 underlying buffer (previously this was only done when deallocating the
2024 memoryview), and gain support for the context management protocol.
2025
Antoine Pitrou079ce542010-09-08 12:37:10 +00002026- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2027 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002043- Issue #4661: email can now parse bytes input and generate either converted

2045
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002046- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2053 gettext.
2054
Éric Araujoef777bd2010-10-05 00:04:20 +00002055- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002056 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002057 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002058 replacement for old handle_accept() and avoids the user to call accept()
2059 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002082- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002083 retry the select() loop instead of bailing out. This is because select() can
2084 incorrectly report a socket as ready for reading (for example, if it received
2085 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002142- Issue #9854: The default read() implementation in io.RawIOBase now handles
2143 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002144
Georg Brandl27a28582010-10-10 09:49:21 +00002145- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2146 supporting the whole socket API (rather than the "raw" _socket.socket
2147 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002148
Georg Brandl27a28582010-10-10 09:49:21 +00002149- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2150 to match the corresponding socket methods.

Éric Araujod8c73c62011-03-21 03:15:22 +01002152- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002153 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002159- Issue #9837: The read() method of ZipExtFile objects (as returned by
2160 ZipFile.open()) could return more bytes than requested.
2161
Georg Brandl27a28582010-10-10 09:49:21 +00002162- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2163 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002164
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002165- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002166 it possible for the user to create self-referencing ordered dictionaries which
2167 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002168 approach of using weakref proxies so that reference cycles never get created
2169 in the first place.
2170
Victor Stinnercb043522010-09-10 23:49:04 +00002171- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2172 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002173 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002174
Georg Brandl27a28582010-10-10 09:49:21 +00002175- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2176 environment variable to set the filesystem encoding at Python startup.
2177 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2178 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002179
Georg Brandl27a28582010-10-10 09:49:21 +00002180- Issue #9410: Various optimizations to the pickle module, leading to speedups
2181 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2182 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002183
Georg Brandl27a28582010-10-10 09:49:21 +00002184- The pprint module now supports printing OrderedDicts in their given order
2185 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002187- Logging: Added QueueHandler class to facilitate logging usage with
2188 multiprocessing.
2189
Georg Brandl27a28582010-10-10 09:49:21 +00002190- Issue #9707: Rewritten reference implementation of threading.local which is
2191 friendlier towards reference cycles. This change is not normally visible
2192 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002193
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002194- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2195 still return the id of the parent process after it has exited. This process
2196 id may even have been reused by another unrelated process.
2197
Georg Brandl27a28582010-10-10 09:49:21 +00002198- Issue #9792: In case of connection failure, socket.create_connection() would
2199 swallow the exception and raise a new one, making it impossible to fetch the
2200 original errno, or to filter timeout errors. Now the original error is
2201 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002203- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2204 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2205 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002207- Updates to the random module:
2208
Georg Brandl27a28582010-10-10 09:49:21 +00002209 * Document which parts of the module are guaranteed to stay the same across
2210 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002211
Georg Brandl27a28582010-10-10 09:49:21 +00002212 * Update the seed() method to use all of the bits in a string instead of just
2213 the hash value. This makes better use of the seed value and assures the
2214 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002215
Georg Brandl27a28582010-10-10 09:49:21 +00002216 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2217 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2218 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002219
2220 * Improved documentation of arguments to randrange(). Issue #9379.

2226 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2227 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002235- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002236 unsupported operation is attempted (for example, writing to a file open only
2237 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002239- hashlib has two new constant attributes: algorithms_guaranteed and
2240 algorithms_avaiable that respectively list the names of hash algorithms
2241 guaranteed to exist in all Python implementations and the names of hash
2242 algorithms available in the current process.
2243
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002244- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002334- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2335 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2336 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00002347- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2348 now removed, since their effect was inexistent in 3.x (the default encoding is
2349 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002350
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002351- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2353
Georg Brandl649971e2010-09-05 17:06:50 +00002354- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2355 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002356

Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002370- Issue #5127: The C functions that access the Unicode Database now accept and
2371 return characters from the full Unicode range, even on narrow unicode builds
2372 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2373 in Python is that unicodedata.numeric() now returns the correct value for
2374 large code points, and repr() may consider more characters as printable.
2375
Victor Stinner6c00c142010-08-17 23:37:11 +00002376- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2377 as a unicode object, instead of a byte string. Function needed to support
2378 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2379 function.
2380
Victor Stinner6961bd62010-08-17 22:26:51 +00002381- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

2384
Georg Brandl649971e2010-09-05 17:06:50 +00002385- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for

Georg Brandl62069d32010-07-31 08:56:11 +00002755 start byte and the continuation byte(s) are now considered invalid, instead of
2756 the number of bytes specified by the start byte. E.g.:
2757 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2758 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2759 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2760 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002790- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002791 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

2804 TypeError instead of giving a DeprecationWarning when a float is parsed using
2805 the 'L' code (for long long). (All other integer codes already raise
2806 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002807
Victor Stinner600d3be2010-06-10 12:00:55 +00002808- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

2810 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2811
Georg Brandl62069d32010-07-31 08:56:11 +00002812- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2813 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002814
2815- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002816 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002817 like bytearray.
2818
Georg Brandl62069d32010-07-31 08:56:11 +00002819- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002820 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00002827- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2828 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2829 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2830 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002832- Issue #8748: Fix two issues with comparisons between complex and integer
2833 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002834 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2835 (2) The comparison raised an OverflowError for large integers, leading to
2836 unpredictable exceptions when combining integers and complex objects in sets
2837 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003139- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3140 variable argument list. `Py_VA_COPY` is equivalent to C99
3141 `va_copy`, but available on all python platforms.
3142
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003143- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3144 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3145 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003155- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003156 function declaration, which was kept for backwards compatibility reasons, is
3157 now removed (the macro was introduced in 1997!).

3167 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3168 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003169 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003179- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3180 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3181 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3195
Georg Brandl62069d32010-07-31 08:56:11 +00003196- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3197 allocator will be automatically disabled when running under Valgrind. This
3198 gives improved memory leak detection when running under Valgrind, while taking
3199 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003274 simply clearing the entire cache on overflow to forgetting the least recently
3275 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003276 applications that use a lot of regular expressions and limits the impact of
3277 the performance hit anytime the cache is exceeded.

3290 module is renamed to `_datetime` and if available, overrides all classes
3291 defined in datetime with fast C impementation. Python implementation is based
3292 on the original python prototype for the datetime module by Tim Peters with
3293 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00003531- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3532 operation raises multiple signals and more than one of those signals is
3533 trapped, the specification determines the order in which the signals should be
3534 handled. In many cases this order wasn't being followed, leading to the wrong

3756 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003758- subprocess.Popen now has restore_signals and start_new_session features. The
3759 default of restore_signals=True is a new behavior compared to earlier Python
3760 versions. This means that signals such as SIGPIPE are not ignored by default
3761 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004254- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004255 compared to other unix systems. In particular, os.getgroups() does not reflect
4256 any changes made using os.setgroups() but basicly always returns the same
4257 information as the id command. os.getgroups() can now return more than 16
4258 groups on MacOSX.

4284 Prior to this change, timezone adjustment in utctimetuple() could produce
4285 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4286 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004288- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4289 directive. When the ``%z`` directive is present in the format string, an
4290 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4291 ``datetime.timezone`` instance constructed from the parsed offset. If both
4292 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4293 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004294
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004295- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004296 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4297 ``datetime.timezone``, return fixed name and UTC offset from their
4298 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4299 returns ``None``. A class attribute, ``utc`` contains an instance
4300 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004316- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4317 with an improved 'binary-split' algorithm that uses fewer multiplications and
4318 allows many of the multiplications to be performed using plain C integer
4319 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4320 arguments.

4324
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004325- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4326 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004327 the result is now always correctly rounded, and is equivalent to ``td /
4328 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004336- Issue #8300: When passing a non-integer argument to struct.pack with any
4337 integer format code, struct.pack first attempts to convert the non-integer
4338 using its __index__ method. If that method is non-existent or raises
4339 TypeError it goes on to try the __int__ method, as described below.

4720 are always None now.
4721
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00004722- Issue #6137: The pickle module now translates module names when loading
4723 or dumping pickles with a 2.x-compatible protocol, in order to make data
4724 sharing and migration easier. This behaviour can be disabled using the
4725 new `fix_imports` optional argument.

4780 that would raise SystemError.
4781
Raymond Hettinger2bcde142009-05-29 04:52:27 +00004782- Issue #5982: staticmethod and classmethod now expose the wrapped
4783 function with __func__.
4784
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00004785- Added support for multiple context managers in the same with-statement.
4786 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00004788- Issue #5829: complex("1e500") no longer raises OverflowError. This
4789 makes it consistent with float("1e500") and interpretation of real
4790 and imaginary literals.
4791
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00004792- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00004796- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
4797 (1) inf and nan strings with trailing whitespace were incorrectly
4798 rejected; (2) parsing of strings representing infinities and nans
4799 was locale aware; and (3) the interpretation of fromhex('-nan')
4800 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00004805- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
4806
R. David Murrayfb123912009-05-28 18:19:00 +00004807- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
4808
R. David Murray1f1b9d32009-05-27 20:56:59 +00004809- Issue #6121: pydoc now ignores leading and trailing spaces in the

4817
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004818- In unittest, using a skipping decorator on a class is now equivalent to
4819 skipping every test on the class. The ClassTestSuite class has been removed.
4820
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004821- Issue #6050: Don't fail extracting a directory from a zipfile if
4822 the directory already exists.
4823
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004824- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4825 than an int, which makes some operations possible under 64-bit Linux (e.g.
4826 DN_MULTISHOT with F_NOTIFY).
4827
Antoine Pitrou716c4442009-05-23 19:04:03 +00004828- Issue #5761: Add the name of the underlying file to the repr() of various
4829 IO objects.
4830
R. David Murraycaa27b72009-05-23 18:49:56 +00004831- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4832 by Musashi Tamura, tests by Marcin Bachry.
4833
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004834- Issue #1983: Fix functions taking or returning a process identifier to use
4835 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4836 a process identifier type wider than the standard C integer type.
4837
R. David Murray87e20742009-05-23 01:30:26 +00004838- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

4849
Antoine Pitroue4501852009-05-14 18:55:55 +00004850- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4851 library. This means, for example, that opening an UTF-16 text file in
4852 append mode doesn't add a BOM at the end of the file if the file isn't
4853 empty.
4854
R. David Murray74b89242009-05-13 17:33:03 +00004855- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4856 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4857 corrects a pydoc regression.
4858
Georg Brandl5f90d792010-08-01 22:31:05 +00004859- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004860 now it does. This also means getfp method now returns the real fp.

4863------------
4864
4865- Issue #6047: fullinstall has been removed because Python 3's executable will
4866 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00004867
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00004868- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00004892- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00004893 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004898What's New in Python 3.1 beta 1?
4899================================
4900
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004901*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004902
4903Core and Builtins
4904-----------------
4905
Mark Dickinson865e01a2009-05-07 16:37:01 +00004906- Issue #5914: Add new C API function PyOS_string_to_double, and
4907 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4908
Eric Smith741191f2009-05-06 13:08:15 +00004909- Issue #3382: float.__format__, complex.__format__, and %-formatting
4910 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4911 affects nan -> NAN and inf -> INF.
4912
Mark Hammond5a607a32009-05-06 08:04:54 +00004913- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4914 in all operations, including splitdrive, split, etc. splitunc() now issues
4915 a PendingDeprecation warning.
4916
Eric Smith63376222009-05-05 14:04:18 +00004917- Issue #5920: For float.__format__, change the behavior with the
4918 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4919 to be like 'g' but with at least one decimal point and with a
4920 default precision of 12. Previously, the behavior the same but with
4921 a default precision of 6. This more closely matches str(), and
4922 reduces surprises when adding alignment flags to the empty
4923 presentation type. This also affects the new complex.__format__ in
4924 the same way.
4925
Martin v. Löwis011e8422009-05-05 04:43:17 +00004926- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4927
R. David Murrayb18500d2009-05-04 22:59:07 +00004928- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4929 shadowed by classtype's, even if it was None. property now
4930 inserts the __doc__ into the subclass instance __dict__.
4931
Antoine Pitrou244651a2009-05-04 18:56:13 +00004932- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4933 sequences. Patch by Nick Barnes and Victor Stinner.
4934
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004935- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004936
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004937- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4938 received a new method, detach(). detach() disconnects the underlying stream
4939 from the buffer or text IO and returns it.
4940
Mark Dickinson33841c32009-05-01 15:37:04 +00004941- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4942 floats with absolute value over 1e50. Also remove length
4943 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4944 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004945
Eric Smith741191f2009-05-06 13:08:15 +00004946- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004947 format(complex(1, 2./3), '.5') now produces a sensible result.
4948
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004949- Issue #5864: Fix empty format code formatting for floats so that it
4950 never gives more than the requested number of significant digits.
4951
Eric Smith6dc46f52009-04-27 20:39:49 +00004952- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4953 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4954
Eric Smithcc32a112009-04-26 21:35:14 +00004955- Issue #5835: Deprecate PyOS_ascii_formatd.
4956
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004957- Issue #4971: Fix titlecase for characters that are their own
4958 titlecase, but not their own uppercase.
4959
Benjamin Peterson193152c2009-04-25 01:08:45 +00004960- Issue #5283: Setting __class__ in __del__ caused a segfault.
4961
Mark Dickinsonad476da2009-04-23 19:14:16 +00004962- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4963 z involves nans, infs or negative zeros.
4964
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004965- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004966
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004967- Issue #1869 (and many duplicates): make round(x, n) correctly
4968 rounded for a float x, by using the decimal <-> binary conversions
4969 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4970 consistently agrees with format(x, '.2f').
4971
Benjamin Petersonae937c02009-04-18 20:54:08 +00004972- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4973 some builtin types.
4974
Eric Smith0923d1d2009-04-16 20:16:10 +00004975- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4976
Eric Smith35e84722009-04-16 20:21:28 +00004977- Issue #5515: str.format() type 'n' combined with commas and leading
4978 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004979
4980- Implement PEP 378, Format Specifier for Thousands Separator, for
4981 floats.
4982
Mark Dickinson3370cce2009-04-17 22:40:53 +00004983- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004984 1e11, not 1e12. This avoids printing 13 significant digits in
4985 situations where only 12 of them are correct. Example problem
4986 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4987 long time.)
4988
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004989- Issue #1580: On most platforms, use a 'short' float repr: for a
4990 finite float x, repr(x) now outputs a string based on the shortest
4991 sequence of decimal digits that rounds to x. Previous behaviour was
4992 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004993 Another minor difference is that the new repr switches to
4994 exponential notation at 1e16 instead of the previous 1e17; this
4995 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004996
4997 There's a new sys attribute sys.float_repr_style, which takes
4998 the value 'short' to indicate that we're using short float repr,
4999 and 'legacy' if the short float repr isn't available for one
5000 reason or another.
5001
5002 The float repr change involves incorporating David Gay's 'perfect
5003 rounding' code into the Python core (it's in Python/dtoa.c). As a
5004 secondary consequence, all string-to-float and float-to-string
5005 conversions (including all float formatting operations) will be
5006 correctly rounded on these platforms.

5012
Georg Brandlabc38772009-04-12 15:51:51 +00005013- The string.maketrans() function is deprecated; there is a new static method
5014 maketrans() on the bytes and bytearray classes. This removes confusion about
5015 the types string.maketrans() is supposed to work with, and mirrors the
5016 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005310- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5311 it now forces its argument to double before testing for infinity.
5312
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005313- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005323- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005324 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00005326- Issue #4707: round(x, n) now returns an integer if x is an integer.
5327 Previously it returned a float.
5328
Antoine Pitroub52ec782009-01-25 16:34:23 +00005329- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5330 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5331 evaluation loop is compiled with a new dispatch mechanism which gives
5332 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00005346
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005347- Issue #4935: The overflow checking code in the expandtabs() method common
5348 to str, bytes and bytearray could be optimized away by the compiler, letting
5349 the interpreter segfault instead of raising an error.
5350
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005351- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5352 __next__ method.
5353
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005354- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

5361
Antoine Pitrouab868312009-01-10 15:40:25 +00005362- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5363 common cases are optimized thanks to a dedicated fast path and a moderate
5364 amount of loop unrolling.
5365
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005366- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5367 collecting the oldest generation) so that allocating lots of objects without
5368 destroying them does not show quadratic performance. Based on a proposal by
5369 Martin von Löwis at
5370 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5371
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005372- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005373 having been closed (for instance, a read() call could return some
5374 previously buffered data). Patch by Dmitry Vasiliev.
5375
Antoine Pitrou05608432009-01-09 18:53:14 +00005376- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5377 flag to work properly. Furthermore, when specifying -u, the text stdout
5378 and stderr streams have line-by-line buffering enabled (the default being
5379 to buffer arbitrary chunks of data).
5380
Raymond Hettinger35631532009-01-09 03:58:09 +00005381- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5382 instead of ints (reducing its size from 4 to 8 times thereby reducing
5383 Python's overall memory).
5384
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005385- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5386 an existing .py counterpart, override the co_filename attributes of all
5387 code objects if the original filename is obsolete (which can happen if the
5388 file has been renamed, moved, or if it is accessed through different paths).
5389 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5390
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005391- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5392 one byte. Also fixes the meaning of len() so that it returns the number of
5393 items, rather than the size in bytes.
5394
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005395- Issue #4075: Use OutputDebugStringW in Py_FatalError.

5408
Georg Brandlccc47b62008-12-28 11:44:14 +00005409- Issue #4759: None is now allowed as the first argument of

5411
Skip Montanaro80072cb2008-12-23 03:51:14 +00005412- Added test case to ensure attempts to read from a file opened for writing

5428 failures on OS X.
5429
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005430- Issue #4597: Fixed several opcodes that weren't always propagating

5432
5433- Issue #4589: Fixed exception handling when the __exit__ function of a

5435
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005436- Issue #4445: Replace "sizeof(PyBytesObject)" with
5437 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5438 bytes instances. On a typical machine this saves 3 bytes of memory
5439 (on average) per allocation of a bytes instance.
5440
Christian Heimesa872de52008-12-05 08:26:55 +00005441- Issue #4533: File read operation was dreadfully slow due to a slowly
5442 growing read buffer. Fixed by using the same growth rate algorithm as
5443 Python 2.x.
5444
Antoine Pitrou5504e892008-12-06 21:27:53 +00005445- Issue #4509: Various issues surrounding resize of bytearray objects to

5447
Georg Brandlf9734072008-12-07 15:30:06 +00005448- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5449 method on file objects with closefd=False. The file descriptor is still
5450 kept open but the file object behaves like a closed file. The ``FileIO``
5451 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005460- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5461 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5462 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5463 of using the replace error handler in PyUnicode_DecodeUTF8().
