Ned Deily657b2de2011-06-28 19:51:30 -070072- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
73 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
74 interpreter process. This could cause failures in non-Distutils subprocesses
75 and was unreliable since tests or user programs could modify the interpreter
76 environment after Distutils set it. Instead, have Distutils set the the
77 deployment target only in the environment of each build subprocess. It is
78 still possible to globally override the default by setting
79 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
80 greater or equal to the default value, the value with which the interpreter
81 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001578 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

1922
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001923- Issue #10068: Global objects which have reference cycles with their module's
1924 dict are now cleared again. This causes issue #7140 to appear again.
1925
Victor Stinner257d38f2010-10-09 10:12:11 +00001926- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001927 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001928
Georg Brandl27a28582010-10-10 09:49:21 +00001929- ast.literal_eval() can now handle negative numbers. It is also a little more
1930 liberal in what it accepts without compromising the safety of the evaluation.
1931 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001932
Benjamin Peterson970d1882010-10-02 17:55:47 +00001933- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1934 result metaclasses can now be ABCs (see #9533).
1935
Victor Stinneraef57e32010-10-02 11:50:49 +00001936- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1937
Victor Stinner5593d8a2010-10-02 11:11:27 +00001938- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001939 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Brett Cannon5305a992010-09-27 21:08:38 +00001947- Issue #7397: Mention that importlib.import_module() is probably what someone

1949
Georg Brandl27a28582010-10-10 09:49:21 +00001950- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1951 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001953- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001954 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00001956- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1957
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001958- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1959 threads are still running. Instead, reinitialize the GIL on a second call to
1960 Py_Initialize().
1961
Georg Brandl27a28582010-10-10 09:49:21 +00001962- All SyntaxErrors now have a column offset and therefore a caret when the error
1963 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001964
Brett Cannonbc2eff32010-09-19 21:39:02 +00001965- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1966 module that was imported, but instead gets the module from sys.modules.
1967
Nick Coghlan37ee8502010-12-03 14:26:13 +00001968- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001969 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001970
Georg Brandl27a28582010-10-10 09:49:21 +00001971- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1972 with a non-empty format string. This is an effort to future-proof user
1973 code. If a derived class does not currently implement __format__ but later
1974 adds its own __format__, it would most likely break user code that had
1975 supplied a format string. This will be changed to a DeprecationWaring in
1976 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001977
Antoine Pitrou1df15362010-09-13 14:16:46 +00001978- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1979 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1980 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1981
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001982- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1983 functions from the libc caused the methods .upper() and lower() to become
1984 locale aware and created subtly wrong results.
1985
Georg Brandl27a28582010-10-10 09:49:21 +00001986- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1987 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001988
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001989- Issue #4617: Previously it was illegal to delete a name from the local
1990 namespace if it occurs as a free variable in a nested block. This limitation
1991 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1992
Georg Brandl27a28582010-10-10 09:49:21 +00001993- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1994 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1995 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1996 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001997
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001998- Issue #9757: memoryview objects get a release() method to release the
1999 underlying buffer (previously this was only done when deallocating the
2000 memoryview), and gain support for the context management protocol.
2001
Antoine Pitrou079ce542010-09-08 12:37:10 +00002002- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2003 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002019- Issue #4661: email can now parse bytes input and generate either converted
2020 7bit output or bytes output. Email version bumped to 5.1.0.
2021
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002022- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2029 gettext.
2030
Éric Araujoef777bd2010-10-05 00:04:20 +00002031- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002032 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002033 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002034 replacement for old handle_accept() and avoids the user to call accept()
2035 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002037- Issue #9065: tarfile no longer uses "root" as the default for the uname and

R. David Murray5397e862010-10-02 15:58:26 +00002043- Issue #1050268: parseaddr now correctly quotes double quote and backslash

2057
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002058- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002059 retry the select() loop instead of bailing out. This is because select() can
2060 incorrectly report a socket as ready for reading (for example, if it received
2061 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002121- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2122 supporting the whole socket API (rather than the "raw" _socket.socket
2123 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002124
Georg Brandl27a28582010-10-10 09:49:21 +00002125- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Éric Araujod8c73c62011-03-21 03:15:22 +01002128- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002129 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002135- Issue #9837: The read() method of ZipExtFile objects (as returned by
2136 ZipFile.open()) could return more bytes than requested.
2137
Georg Brandl27a28582010-10-10 09:49:21 +00002138- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2139 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002140
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002141- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002142 it possible for the user to create self-referencing ordered dictionaries which
2143 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002144 approach of using weakref proxies so that reference cycles never get created
2145 in the first place.
2146
Victor Stinnercb043522010-09-10 23:49:04 +00002147- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2148 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002149 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002150
Georg Brandl27a28582010-10-10 09:49:21 +00002151- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2152 environment variable to set the filesystem encoding at Python startup.
2153 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2154 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002155
Georg Brandl27a28582010-10-10 09:49:21 +00002156- Issue #9410: Various optimizations to the pickle module, leading to speedups
2157 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2158 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002159
Georg Brandl27a28582010-10-10 09:49:21 +00002160- The pprint module now supports printing OrderedDicts in their given order
2161 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002163- Logging: Added QueueHandler class to facilitate logging usage with
2164 multiprocessing.
2165
Georg Brandl27a28582010-10-10 09:49:21 +00002166- Issue #9707: Rewritten reference implementation of threading.local which is
2167 friendlier towards reference cycles. This change is not normally visible
2168 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002169
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002170- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2171 still return the id of the parent process after it has exited. This process
2172 id may even have been reused by another unrelated process.
2173
Georg Brandl27a28582010-10-10 09:49:21 +00002174- Issue #9792: In case of connection failure, socket.create_connection() would
2175 swallow the exception and raise a new one, making it impossible to fetch the
2176 original errno, or to filter timeout errors. Now the original error is
2177 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002179- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2180 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2181 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002182
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002183- Updates to the random module:
2184
Georg Brandl27a28582010-10-10 09:49:21 +00002185 * Document which parts of the module are guaranteed to stay the same across
2186 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002187
Georg Brandl27a28582010-10-10 09:49:21 +00002188 * Update the seed() method to use all of the bits in a string instead of just
2189 the hash value. This makes better use of the seed value and assures the
2190 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002191
Georg Brandl27a28582010-10-10 09:49:21 +00002192 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2193 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2194 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002195
2196 * Improved documentation of arguments to randrange(). Issue #9379.

2202 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2203 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002211- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002212 unsupported operation is attempted (for example, writing to a file open only
2213 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002215- hashlib has two new constant attributes: algorithms_guaranteed and
2216 algorithms_avaiable that respectively list the names of hash algorithms
2217 guaranteed to exist in all Python implementations and the names of hash
2218 algorithms available in the current process.
2219
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002220- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002310- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2311 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002323- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2324 now removed, since their effect was inexistent in 3.x (the default encoding is

2347 return characters from the full Unicode range, even on narrow unicode builds
2348 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2349 in Python is that unicodedata.numeric() now returns the correct value for
2350 large code points, and repr() may consider more characters as printable.
2351
Victor Stinner6c00c142010-08-17 23:37:11 +00002352- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Ezio Melotti57221d02010-07-01 07:32:02 +00002730- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002731 start byte and the continuation byte(s) are now considered invalid, instead of
2732 the number of bytes specified by the start byte. E.g.:
2733 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2734 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2735 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2736 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002766- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002767 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00002779- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2780 TypeError instead of giving a DeprecationWarning when a float is parsed using
2781 the 'L' code (for long long). (All other integer codes already raise
2782 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002783
Victor Stinner600d3be2010-06-10 12:00:55 +00002784- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

2786 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2787
Georg Brandl62069d32010-07-31 08:56:11 +00002788- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2789 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002790
2791- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002792 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002793 like bytearray.
2794
Georg Brandl62069d32010-07-31 08:56:11 +00002795- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002796 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00002803- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2804 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2805 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2806 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002807
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002808- Issue #8748: Fix two issues with comparisons between complex and integer
2809 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002810 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2811 (2) The comparison raised an OverflowError for large integers, leading to
2812 unpredictable exceptions when combining integers and complex objects in sets
2813 or dicts.

3251 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003252 applications that use a lot of regular expressions and limits the impact of
3253 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003662- Issue #7279: Comparisons involving a Decimal signaling NaN now signal

Georg Brandl62069d32010-07-31 08:56:11 +00003667- Issue #2531: Comparison operations between floats and Decimal instances now
3668 return a result based on the numeric values of the operands; previously they
3669 returned an arbitrary result based on the relative ordering of id(float) and
3670 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3671 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003672
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003673- Added a subtract() method to collections.Counter().
3674
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003675- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003676 argument `-` which tells it to read files to compile from stdin. Each line is

3686 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3687 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003734- subprocess.Popen now has restore_signals and start_new_session features. The
3735 default of restore_signals=True is a new behavior compared to earlier Python
3736 versions. This means that signals such as SIGPIPE are not ignored by default
3737 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004014 default when instantiating a `threading.RLock` object. This makes recursive
4015 locks as fast as regular non-recursive locks (previously, they were slower by

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004225- Issue #9959: Tweak formula used for computing math.log of an integer,
4226 making it marginally more accurate for exact powers of 2.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004230- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004231 compared to other unix systems. In particular, os.getgroups() does not reflect
4232 any changes made using os.setgroups() but basicly always returns the same
4233 information as the id command. os.getgroups() can now return more than 16
4234 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004259- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4260 Prior to this change, timezone adjustment in utctimetuple() could produce
4261 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4262 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00004263
Georg Brandl62069d32010-07-31 08:56:11 +00004264- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4265 directive. When the ``%z`` directive is present in the format string, an
4266 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4267 ``datetime.timezone`` instance constructed from the parsed offset. If both
4268 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4269 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004270
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004271- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004272 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4273 ``datetime.timezone``, return fixed name and UTC offset from their
4274 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4275 returns ``None``. A class attribute, ``utc`` contains an instance
4276 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004292- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4293 with an improved 'binary-split' algorithm that uses fewer multiplications and
4294 allows many of the multiplications to be performed using plain C integer
4295 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4296 arguments.

4299 overflow checks in the audioop module.
4300
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004301- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4302 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004303 the result is now always correctly rounded, and is equivalent to ``td /
4304 timedelta(seconds=1)``.

4311
Mark Dickinsonc5935772010-04-03 15:54:36 +00004312- Issue #8300: When passing a non-integer argument to struct.pack with any
4313 integer format code, struct.pack first attempts to convert the non-integer
4314 using its __index__ method. If that method is non-existent or raises
4315 TypeError it goes on to try the __int__ method, as described below.
4316
Matthias Klosea8349752010-03-15 13:25:28 +00004317- Issue #8142: Update libffi to the 3.0.9 release.

4696 are always None now.
4697
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00004698- Issue #6137: The pickle module now translates module names when loading
4699 or dumping pickles with a 2.x-compatible protocol, in order to make data
4700 sharing and migration easier. This behaviour can be disabled using the
4701 new `fix_imports` optional argument.

4754
Eric Smith41669ca2009-05-23 14:23:22 +00004755- Issue #6089: Fixed str.format with certain invalid field specifiers
4756 that would raise SystemError.
4757
Raymond Hettinger2bcde142009-05-29 04:52:27 +00004758- Issue #5982: staticmethod and classmethod now expose the wrapped
4759 function with __func__.
4760
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00004761- Added support for multiple context managers in the same with-statement.
4762 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00004764- Issue #5829: complex("1e500") no longer raises OverflowError. This
4765 makes it consistent with float("1e500") and interpretation of real
4766 and imaginary literals.
4767
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00004768- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00004772- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
4773 (1) inf and nan strings with trailing whitespace were incorrectly
4774 rejected; (2) parsing of strings representing infinities and nans
4775 was locale aware; and (3) the interpretation of fromhex('-nan')
4776 didn't match that of float('-nan').

4780
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00004781- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
4782
R. David Murrayfb123912009-05-28 18:19:00 +00004783- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
4784
R. David Murray1f1b9d32009-05-27 20:56:59 +00004785- Issue #6121: pydoc now ignores leading and trailing spaces in the

4792 names: cls, self, tuple, itemgetter, and property.
4793
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004794- In unittest, using a skipping decorator on a class is now equivalent to
4795 skipping every test on the class. The ClassTestSuite class has been removed.
4796
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004797- Issue #6050: Don't fail extracting a directory from a zipfile if
4798 the directory already exists.
4799
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004800- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4801 than an int, which makes some operations possible under 64-bit Linux (e.g.
4802 DN_MULTISHOT with F_NOTIFY).
4803
Antoine Pitrou716c4442009-05-23 19:04:03 +00004804- Issue #5761: Add the name of the underlying file to the repr() of various
4805 IO objects.
4806
R. David Murraycaa27b72009-05-23 18:49:56 +00004807- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4808 by Musashi Tamura, tests by Marcin Bachry.
4809
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004810- Issue #1983: Fix functions taking or returning a process identifier to use
4811 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4812 a process identifier type wider than the standard C integer type.
4813
R. David Murray87e20742009-05-23 01:30:26 +00004814- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

4825
Antoine Pitroue4501852009-05-14 18:55:55 +00004826- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4827 library. This means, for example, that opening an UTF-16 text file in
4828 append mode doesn't add a BOM at the end of the file if the file isn't
4829 empty.
4830
R. David Murray74b89242009-05-13 17:33:03 +00004831- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4832 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4833 corrects a pydoc regression.
4834
Georg Brandl5f90d792010-08-01 22:31:05 +00004835- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004836 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00004868- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00004869 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004878
4879Core and Builtins
4880-----------------
4881
Mark Dickinson865e01a2009-05-07 16:37:01 +00004882- Issue #5914: Add new C API function PyOS_string_to_double, and
4883 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4884
Eric Smith741191f2009-05-06 13:08:15 +00004885- Issue #3382: float.__format__, complex.__format__, and %-formatting
4886 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4887 affects nan -> NAN and inf -> INF.
4888
Mark Hammond5a607a32009-05-06 08:04:54 +00004889- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4890 in all operations, including splitdrive, split, etc. splitunc() now issues
4891 a PendingDeprecation warning.
4892
Eric Smith63376222009-05-05 14:04:18 +00004893- Issue #5920: For float.__format__, change the behavior with the
4894 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4895 to be like 'g' but with at least one decimal point and with a
4896 default precision of 12. Previously, the behavior the same but with
4897 a default precision of 6. This more closely matches str(), and
4898 reduces surprises when adding alignment flags to the empty
4899 presentation type. This also affects the new complex.__format__ in
4900 the same way.
4901
Martin v. Löwis011e8422009-05-05 04:43:17 +00004902- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4903
R. David Murrayb18500d2009-05-04 22:59:07 +00004904- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4905 shadowed by classtype's, even if it was None. property now
4906 inserts the __doc__ into the subclass instance __dict__.
4907
Antoine Pitrou244651a2009-05-04 18:56:13 +00004908- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4909 sequences. Patch by Nick Barnes and Victor Stinner.
4910
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004911- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004912
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004913- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4914 received a new method, detach(). detach() disconnects the underlying stream
4915 from the buffer or text IO and returns it.
4916
Mark Dickinson33841c32009-05-01 15:37:04 +00004917- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4918 floats with absolute value over 1e50. Also remove length
4919 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4920 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004921
Eric Smith741191f2009-05-06 13:08:15 +00004922- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004923 format(complex(1, 2./3), '.5') now produces a sensible result.
4924
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004925- Issue #5864: Fix empty format code formatting for floats so that it
4926 never gives more than the requested number of significant digits.
4927
Eric Smith6dc46f52009-04-27 20:39:49 +00004928- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4929 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4930
Eric Smithcc32a112009-04-26 21:35:14 +00004931- Issue #5835: Deprecate PyOS_ascii_formatd.
4932
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004933- Issue #4971: Fix titlecase for characters that are their own
4934 titlecase, but not their own uppercase.
4935
Benjamin Peterson193152c2009-04-25 01:08:45 +00004936- Issue #5283: Setting __class__ in __del__ caused a segfault.
4937
Mark Dickinsonad476da2009-04-23 19:14:16 +00004938- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4939 z involves nans, infs or negative zeros.
4940
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004941- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004942
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004943- Issue #1869 (and many duplicates): make round(x, n) correctly
4944 rounded for a float x, by using the decimal <-> binary conversions
4945 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4946 consistently agrees with format(x, '.2f').
4947
Benjamin Petersonae937c02009-04-18 20:54:08 +00004948- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4949 some builtin types.
4950
Eric Smith0923d1d2009-04-16 20:16:10 +00004951- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4952
Eric Smith35e84722009-04-16 20:21:28 +00004953- Issue #5515: str.format() type 'n' combined with commas and leading
4954 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004955
4956- Implement PEP 378, Format Specifier for Thousands Separator, for
4957 floats.
4958
Mark Dickinson3370cce2009-04-17 22:40:53 +00004959- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004960 1e11, not 1e12. This avoids printing 13 significant digits in
4961 situations where only 12 of them are correct. Example problem
4962 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4963 long time.)
4964
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004965- Issue #1580: On most platforms, use a 'short' float repr: for a
4966 finite float x, repr(x) now outputs a string based on the shortest
4967 sequence of decimal digits that rounds to x. Previous behaviour was
4968 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004969 Another minor difference is that the new repr switches to
4970 exponential notation at 1e16 instead of the previous 1e17; this
4971 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004972
4973 There's a new sys attribute sys.float_repr_style, which takes
4974 the value 'short' to indicate that we're using short float repr,
4975 and 'legacy' if the short float repr isn't available for one
4976 reason or another.
4977
4978 The float repr change involves incorporating David Gay's 'perfect
4979 rounding' code into the Python core (it's in Python/dtoa.c). As a
4980 secondary consequence, all string-to-float and float-to-string
4981 conversions (including all float formatting operations) will be
4982 correctly rounded on these platforms.
4983
Georg Brandl5f90d792010-08-01 22:31:05 +00004984 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004985 this change does not apply.
4986

4991 the types string.maketrans() is supposed to work with, and mirrors the
4992 methods available on the str class.

5285
Mark Dickinson87ec0852009-02-09 17:15:59 +00005286- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5287 it now forces its argument to double before testing for infinity.
5288
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005289- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5290 returns a non-number type.

Mark Dickinsonc008a172009-02-01 13:59:22 +00005294- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5295 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005296 the type definition cmpfunc. The tp_compare slot has been renamed
5297 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005299- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005300 were suppressing all exceptions. These include list() and bytearray().
5301
Mark Dickinson1124e712009-01-28 21:25:58 +00005302- Issue #4707: round(x, n) now returns an integer if x is an integer.
5303 Previously it returned a float.
5304
Antoine Pitroub52ec782009-01-25 16:34:23 +00005305- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5306 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5307 evaluation loop is compiled with a new dispatch mechanism which gives
5308 speedups of up to 20%, depending on the system, on various benchmarks.

5319
Mark Dickinson8055afd2009-01-17 10:04:45 +00005320- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005321 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005322
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005323- Issue #4935: The overflow checking code in the expandtabs() method common
5324 to str, bytes and bytearray could be optimized away by the compiler, letting
5325 the interpreter segfault instead of raising an error.
5326
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005327- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5328 __next__ method.
5329
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005330- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5331 function no longer attempt to call the __long__ slot to convert an object
5332 to an integer. Only the __int__ and __trunc__ slots are examined.

Antoine Pitrouab868312009-01-10 15:40:25 +00005338- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5339 common cases are optimized thanks to a dedicated fast path and a moderate
5340 amount of loop unrolling.
5341
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005342- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5343 collecting the oldest generation) so that allocating lots of objects without
5344 destroying them does not show quadratic performance. Based on a proposal by
5345 Martin von Löwis at
5346 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5347
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005348- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005349 having been closed (for instance, a read() call could return some
5350 previously buffered data). Patch by Dmitry Vasiliev.
5351
Antoine Pitrou05608432009-01-09 18:53:14 +00005352- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5353 flag to work properly. Furthermore, when specifying -u, the text stdout
5354 and stderr streams have line-by-line buffering enabled (the default being
5355 to buffer arbitrary chunks of data).
5356
Raymond Hettinger35631532009-01-09 03:58:09 +00005357- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5358 instead of ints (reducing its size from 4 to 8 times thereby reducing
5359 Python's overall memory).
5360
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005361- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5362 an existing .py counterpart, override the co_filename attributes of all
5363 code objects if the original filename is obsolete (which can happen if the
5364 file has been renamed, moved, or if it is accessed through different paths).
5365 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5366
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005367- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5368 one byte. Also fixes the meaning of len() so that it returns the number of
5369 items, rather than the size in bytes.
5370
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005371- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005373- Issue #4747: When the terminal does not use utf-8, executing a script with
5374 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5375
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005376- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5380 did not get collected.
5381
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005382- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5383 where the tp_hash and tp_dict slots are both NULL.
5384
Georg Brandlccc47b62008-12-28 11:44:14 +00005385- Issue #4759: None is now allowed as the first argument of
5386 bytearray.translate(). It was always allowed for bytes.translate().
5387
Skip Montanaro80072cb2008-12-23 03:51:14 +00005388- Added test case to ensure attempts to read from a file opened for writing
5389 fail.

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005402- Issue #2173: When getting device encoding, check that return value of
5403 nl_langinfo is not the empty string. This was causing silent build
5404 failures on OS X.
5405
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005406- Issue #4597: Fixed several opcodes that weren't always propagating

5408
5409- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005410 context manager returns a value that cannot be converted to a bool.
5411
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005412- Issue #4445: Replace "sizeof(PyBytesObject)" with
5413 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5414 bytes instances. On a typical machine this saves 3 bytes of memory
5415 (on average) per allocation of a bytes instance.
5416
Christian Heimesa872de52008-12-05 08:26:55 +00005417- Issue #4533: File read operation was dreadfully slow due to a slowly
5418 growing read buffer. Fixed by using the same growth rate algorithm as
5419 Python 2.x.
5420
Antoine Pitrou5504e892008-12-06 21:27:53 +00005421- Issue #4509: Various issues surrounding resize of bytearray objects to
5422 which there are buffer exports (e.g. memoryview instances).
5423
Georg Brandlf9734072008-12-07 15:30:06 +00005424- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5425 method on file objects with closefd=False. The file descriptor is still
5426 kept open but the file object behaves like a closed file. The ``FileIO``
5427 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005436- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5437 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5438 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5439 of using the replace error handler in PyUnicode_DecodeUTF8().
