656 is made for all headers in any serialized message at serialization time. This
657 provides protection against header injection attacks.

1656-----------------
1657
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001658- Issue #10068: Global objects which have reference cycles with their module's
1659 dict are now cleared again. This causes issue #7140 to appear again.
1660
Victor Stinner257d38f2010-10-09 10:12:11 +00001661- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001662 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001663
Georg Brandl27a28582010-10-10 09:49:21 +00001664- ast.literal_eval() can now handle negative numbers. It is also a little more
1665 liberal in what it accepts without compromising the safety of the evaluation.
1666 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001667
Benjamin Peterson970d1882010-10-02 17:55:47 +00001668- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1669 result metaclasses can now be ABCs (see #9533).
1670
Victor Stinneraef57e32010-10-02 11:50:49 +00001671- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1672
Victor Stinner5593d8a2010-10-02 11:11:27 +00001673- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001674 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
1675 32 bits wchar_t (eg. Linux in narrow build).

1681
Brett Cannon5305a992010-09-27 21:08:38 +00001682- Issue #7397: Mention that importlib.import_module() is probably what someone
1683 really wants to be using in __import__'s docstring.
1684
Georg Brandl27a28582010-10-10 09:49:21 +00001685- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1686 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00001687
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001688- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001689 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00001691- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1692
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001693- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1694 threads are still running. Instead, reinitialize the GIL on a second call to
1695 Py_Initialize().
1696
Georg Brandl27a28582010-10-10 09:49:21 +00001697- All SyntaxErrors now have a column offset and therefore a caret when the error
1698 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001699
Brett Cannonbc2eff32010-09-19 21:39:02 +00001700- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1701 module that was imported, but instead gets the module from sys.modules.
1702
Nick Coghlan37ee8502010-12-03 14:26:13 +00001703- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001704 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001705
Georg Brandl27a28582010-10-10 09:49:21 +00001706- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1707 with a non-empty format string. This is an effort to future-proof user
1708 code. If a derived class does not currently implement __format__ but later
1709 adds its own __format__, it would most likely break user code that had
1710 supplied a format string. This will be changed to a DeprecationWaring in
1711 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001712
Antoine Pitrou1df15362010-09-13 14:16:46 +00001713- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1714 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1715 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1716
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001717- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1718 functions from the libc caused the methods .upper() and lower() to become
1719 locale aware and created subtly wrong results.
1720
Georg Brandl27a28582010-10-10 09:49:21 +00001721- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1722 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001723
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001724- Issue #4617: Previously it was illegal to delete a name from the local
1725 namespace if it occurs as a free variable in a nested block. This limitation
1726 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1727
Georg Brandl27a28582010-10-10 09:49:21 +00001728- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1729 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1730 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1731 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001732
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001733- Issue #9757: memoryview objects get a release() method to release the
1734 underlying buffer (previously this was only done when deallocating the
1735 memoryview), and gain support for the context management protocol.
1736
Antoine Pitrou079ce542010-09-08 12:37:10 +00001737- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1738 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00001754- Issue #4661: email can now parse bytes input and generate either converted
1755 7bit output or bytes output. Email version bumped to 5.1.0.
1756
Antoine Pitrou59fdd672010-10-08 10:37:08 +00001757- Issue #1589: Add ssl.match_hostname(), to help implement server identity

1759
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00001760- Issue #9759: GzipFile now raises ValueError when an operation is attempted

1762
Éric Araujo6108bf52010-10-04 23:52:37 +00001763- Issue #9042: Fix interaction of custom translation classes and caching in
1764 gettext.
1765
Éric Araujoef777bd2010-10-05 00:04:20 +00001766- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001767 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001768 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001769 replacement for old handle_accept() and avoids the user to call accept()
1770 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00001772- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001793- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001794 retry the select() loop instead of bailing out. This is because select() can
1795 incorrectly report a socket as ready for reading (for example, if it received
1796 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00001856- Issue #1552: socket.socketpair() now returns regular socket.socket objects
1857 supporting the whole socket API (rather than the "raw" _socket.socket
1858 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00001859
Georg Brandl27a28582010-10-10 09:49:21 +00001860- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Éric Araujod8c73c62011-03-21 03:15:22 +01001863- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00001864 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00001870- Issue #9837: The read() method of ZipExtFile objects (as returned by
1871 ZipFile.open()) could return more bytes than requested.
1872
Georg Brandl27a28582010-10-10 09:49:21 +00001873- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
1874 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00001875
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001876- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001877 it possible for the user to create self-referencing ordered dictionaries which
1878 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001879 approach of using weakref proxies so that reference cycles never get created
1880 in the first place.
1881
Victor Stinnercb043522010-09-10 23:49:04 +00001882- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
1883 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00001884 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00001885
Georg Brandl27a28582010-10-10 09:49:21 +00001886- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
1887 environment variable to set the filesystem encoding at Python startup.
1888 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1889 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001890
Georg Brandl27a28582010-10-10 09:49:21 +00001891- Issue #9410: Various optimizations to the pickle module, leading to speedups
1892 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
1893 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00001894
Georg Brandl27a28582010-10-10 09:49:21 +00001895- The pprint module now supports printing OrderedDicts in their given order
1896 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00001898- Logging: Added QueueHandler class to facilitate logging usage with
1899 multiprocessing.
1900
Georg Brandl27a28582010-10-10 09:49:21 +00001901- Issue #9707: Rewritten reference implementation of threading.local which is
1902 friendlier towards reference cycles. This change is not normally visible
1903 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001904
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001905- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1906 still return the id of the parent process after it has exited. This process
1907 id may even have been reused by another unrelated process.
1908
Georg Brandl27a28582010-10-10 09:49:21 +00001909- Issue #9792: In case of connection failure, socket.create_connection() would
1910 swallow the exception and raise a new one, making it impossible to fetch the
1911 original errno, or to filter timeout errors. Now the original error is
1912 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00001914- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1915 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1916 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00001917
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001918- Updates to the random module:
1919
Georg Brandl27a28582010-10-10 09:49:21 +00001920 * Document which parts of the module are guaranteed to stay the same across
1921 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001922
Georg Brandl27a28582010-10-10 09:49:21 +00001923 * Update the seed() method to use all of the bits in a string instead of just
1924 the hash value. This makes better use of the seed value and assures the
1925 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001926
Georg Brandl27a28582010-10-10 09:49:21 +00001927 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1928 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1929 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001930
1931 * Improved documentation of arguments to randrange(). Issue #9379.

1937 cases now also have assertWarns and assertWarnsRegexp methods to check that a
1938 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00001939
Georg Brandl27a28582010-10-10 09:49:21 +00001940- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
1941 their contents without duplicating them. The view is both readable and
1942 writable.

1945
Antoine Pitrou0d739d72010-09-05 23:01:12 +00001946- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00001947 unsupported operation is attempted (for example, writing to a file open only
1948 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00001950- hashlib has two new constant attributes: algorithms_guaranteed and
1951 algorithms_avaiable that respectively list the names of hash algorithms
1952 guaranteed to exist in all Python implementations and the names of hash
1953 algorithms available in the current process.
1954
Brian Quinlanaf38dc52010-09-21 12:28:43 +00001955- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002045- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2046 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002058- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2059 now removed, since their effect was inexistent in 3.x (the default encoding is
2060 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002061
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002062- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2082 return characters from the full Unicode range, even on narrow unicode builds
2083 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2084 in Python is that unicodedata.numeric() now returns the correct value for
2085 large code points, and repr() may consider more characters as printable.
2086
Victor Stinner6c00c142010-08-17 23:37:11 +00002087- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

2089 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2090 function.

Georg Brandl649971e2010-09-05 17:06:50 +00002096- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2097 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002098

Ezio Melotti57221d02010-07-01 07:32:02 +00002465- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002466 start byte and the continuation byte(s) are now considered invalid, instead of
2467 the number of bytes specified by the start byte. E.g.:
2468 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2469 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2470 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2471 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002501- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002502 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00002514- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2515 TypeError instead of giving a DeprecationWarning when a float is parsed using
2516 the 'L' code (for long long). (All other integer codes already raise
2517 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002518
Victor Stinner600d3be2010-06-10 12:00:55 +00002519- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

2521 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2522
Georg Brandl62069d32010-07-31 08:56:11 +00002523- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2524 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002525
2526- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002527 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002528 like bytearray.
2529
Georg Brandl62069d32010-07-31 08:56:11 +00002530- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002531 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00002538- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2539 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2540 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2541 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002542
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002543- Issue #8748: Fix two issues with comparisons between complex and integer
2544 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002545 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2546 (2) The comparison raised an OverflowError for large integers, leading to
2547 unpredictable exceptions when combining integers and complex objects in sets
2548 or dicts.

2986 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002987 applications that use a lot of regular expressions and limits the impact of
2988 the performance hit anytime the cache is exceeded.

3001 module is renamed to `_datetime` and if available, overrides all classes
3002 defined in datetime with fast C impementation. Python implementation is based
3003 on the original python prototype for the datetime module by Tim Peters with
3004 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00003397- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3398 InvalidOperation instead of returning False. (Comparisons involving a quiet
3399 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3400 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003401
Georg Brandl62069d32010-07-31 08:56:11 +00003402- Issue #2531: Comparison operations between floats and Decimal instances now
3403 return a result based on the numeric values of the operands; previously they
3404 returned an arbitrary result based on the relative ordering of id(float) and
3405 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3406 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003407
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003408- Added a subtract() method to collections.Counter().
3409
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003410- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003411 argument `-` which tells it to read files to compile from stdin. Each line is

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003415- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

3421 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3422 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003469- subprocess.Popen now has restore_signals and start_new_session features. The
3470 default of restore_signals=True is a new behavior compared to earlier Python
3471 versions. This means that signals such as SIGPIPE are not ignored by default
3472 in subprocesses launched by Python (Issue #1652).

Mark Dickinsonfa41e602010-09-28 07:22:27 +00003960- Issue #9959: Tweak formula used for computing math.log of an integer,
3961 making it marginally more accurate for exact powers of 2.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003965- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003966 compared to other unix systems. In particular, os.getgroups() does not reflect
3967 any changes made using os.setgroups() but basicly always returns the same
3968 information as the id command. os.getgroups() can now return more than 16
3969 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00003994- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
3995 Prior to this change, timezone adjustment in utctimetuple() could produce
3996 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
3997 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00003998
Georg Brandl62069d32010-07-31 08:56:11 +00003999- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4000 directive. When the ``%z`` directive is present in the format string, an
4001 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4002 ``datetime.timezone`` instance constructed from the parsed offset. If both
4003 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4004 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004005
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004006- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004007 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4008 ``datetime.timezone``, return fixed name and UTC offset from their
4009 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4010 returns ``None``. A class attribute, ``utc`` contains an instance
4011 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004027- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4028 with an improved 'binary-split' algorithm that uses fewer multiplications and
4029 allows many of the multiplications to be performed using plain C integer
4030 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4031 arguments.

4034 overflow checks in the audioop module.
4035
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004036- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4037 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004038 the result is now always correctly rounded, and is equivalent to ``td /
4039 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004040

Mark Dickinsonc5935772010-04-03 15:54:36 +00004047- Issue #8300: When passing a non-integer argument to struct.pack with any
4048 integer format code, struct.pack first attempts to convert the non-integer
4049 using its __index__ method. If that method is non-existent or raises
4050 TypeError it goes on to try the __int__ method, as described below.
4051

4431 are always None now.
4432
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00004433- Issue #6137: The pickle module now translates module names when loading
4434 or dumping pickles with a 2.x-compatible protocol, in order to make data
4435 sharing and migration easier. This behaviour can be disabled using the
4436 new `fix_imports` optional argument.

4489
Eric Smith41669ca2009-05-23 14:23:22 +00004490- Issue #6089: Fixed str.format with certain invalid field specifiers
4491 that would raise SystemError.
4492
Raymond Hettinger2bcde142009-05-29 04:52:27 +00004493- Issue #5982: staticmethod and classmethod now expose the wrapped
4494 function with __func__.
4495
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00004496- Added support for multiple context managers in the same with-statement.
4497 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00004499- Issue #5829: complex("1e500") no longer raises OverflowError. This
4500 makes it consistent with float("1e500") and interpretation of real
4501 and imaginary literals.
4502
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00004503- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00004507- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
4508 (1) inf and nan strings with trailing whitespace were incorrectly
4509 rejected; (2) parsing of strings representing infinities and nans
4510 was locale aware; and (3) the interpretation of fromhex('-nan')
4511 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00004516- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
4517
R. David Murrayfb123912009-05-28 18:19:00 +00004518- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
4519
R. David Murray1f1b9d32009-05-27 20:56:59 +00004520- Issue #6121: pydoc now ignores leading and trailing spaces in the
4521 argument to the 'help' function.
4522
Georg Brandlfaf41492009-05-26 18:31:11 +00004523- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
4524 arguments for strings with a space in them.
4525
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00004526- collections.namedtuple() was not working with the following field
4527 names: cls, self, tuple, itemgetter, and property.
4528
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004529- In unittest, using a skipping decorator on a class is now equivalent to
4530 skipping every test on the class. The ClassTestSuite class has been removed.
4531
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004532- Issue #6050: Don't fail extracting a directory from a zipfile if
4533 the directory already exists.
4534
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004535- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4536 than an int, which makes some operations possible under 64-bit Linux (e.g.
4537 DN_MULTISHOT with F_NOTIFY).
4538
Antoine Pitrou716c4442009-05-23 19:04:03 +00004539- Issue #5761: Add the name of the underlying file to the repr() of various
4540 IO objects.
4541
R. David Murraycaa27b72009-05-23 18:49:56 +00004542- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4543 by Musashi Tamura, tests by Marcin Bachry.
4544
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004545- Issue #1983: Fix functions taking or returning a process identifier to use
4546 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4547 a process identifier type wider than the standard C integer type.
4548
R. David Murray87e20742009-05-23 01:30:26 +00004549- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

4560
Antoine Pitroue4501852009-05-14 18:55:55 +00004561- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4562 library. This means, for example, that opening an UTF-16 text file in
4563 append mode doesn't add a BOM at the end of the file if the file isn't
4564 empty.
4565
R. David Murray74b89242009-05-13 17:33:03 +00004566- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4567 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4568 corrects a pydoc regression.
4569
Georg Brandl5f90d792010-08-01 22:31:05 +00004570- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004571 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00004603- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00004604 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004609What's New in Python 3.1 beta 1?
4610================================

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004612*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004613
4614Core and Builtins
4615-----------------
4616
Mark Dickinson865e01a2009-05-07 16:37:01 +00004617- Issue #5914: Add new C API function PyOS_string_to_double, and
4618 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4619
Eric Smith741191f2009-05-06 13:08:15 +00004620- Issue #3382: float.__format__, complex.__format__, and %-formatting
4621 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4622 affects nan -> NAN and inf -> INF.
4623
Mark Hammond5a607a32009-05-06 08:04:54 +00004624- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4625 in all operations, including splitdrive, split, etc. splitunc() now issues
4626 a PendingDeprecation warning.
4627
Eric Smith63376222009-05-05 14:04:18 +00004628- Issue #5920: For float.__format__, change the behavior with the
4629 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4630 to be like 'g' but with at least one decimal point and with a
4631 default precision of 12. Previously, the behavior the same but with
4632 a default precision of 6. This more closely matches str(), and
4633 reduces surprises when adding alignment flags to the empty
4634 presentation type. This also affects the new complex.__format__ in
4635 the same way.
4636
Martin v. Löwis011e8422009-05-05 04:43:17 +00004637- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4638
R. David Murrayb18500d2009-05-04 22:59:07 +00004639- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4640 shadowed by classtype's, even if it was None. property now
4641 inserts the __doc__ into the subclass instance __dict__.
4642
Antoine Pitrou244651a2009-05-04 18:56:13 +00004643- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4644 sequences. Patch by Nick Barnes and Victor Stinner.
4645
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004646- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004647
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004648- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4649 received a new method, detach(). detach() disconnects the underlying stream
4650 from the buffer or text IO and returns it.
4651
Mark Dickinson33841c32009-05-01 15:37:04 +00004652- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4653 floats with absolute value over 1e50. Also remove length
4654 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4655 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004656
Eric Smith741191f2009-05-06 13:08:15 +00004657- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004658 format(complex(1, 2./3), '.5') now produces a sensible result.
4659
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004660- Issue #5864: Fix empty format code formatting for floats so that it
4661 never gives more than the requested number of significant digits.
4662
Eric Smith6dc46f52009-04-27 20:39:49 +00004663- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4664 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4665
Eric Smithcc32a112009-04-26 21:35:14 +00004666- Issue #5835: Deprecate PyOS_ascii_formatd.
4667
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004668- Issue #4971: Fix titlecase for characters that are their own
4669 titlecase, but not their own uppercase.
4670
Benjamin Peterson193152c2009-04-25 01:08:45 +00004671- Issue #5283: Setting __class__ in __del__ caused a segfault.
4672
Mark Dickinsonad476da2009-04-23 19:14:16 +00004673- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4674 z involves nans, infs or negative zeros.
4675
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004676- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004677
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004678- Issue #1869 (and many duplicates): make round(x, n) correctly
4679 rounded for a float x, by using the decimal <-> binary conversions
4680 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4681 consistently agrees with format(x, '.2f').
4682
Benjamin Petersonae937c02009-04-18 20:54:08 +00004683- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4684 some builtin types.
4685
Eric Smith0923d1d2009-04-16 20:16:10 +00004686- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4687
Eric Smith35e84722009-04-16 20:21:28 +00004688- Issue #5515: str.format() type 'n' combined with commas and leading
4689 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004690
4691- Implement PEP 378, Format Specifier for Thousands Separator, for
4692 floats.
4693
Mark Dickinson3370cce2009-04-17 22:40:53 +00004694- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004695 1e11, not 1e12. This avoids printing 13 significant digits in
4696 situations where only 12 of them are correct. Example problem
4697 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4698 long time.)
4699
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004700- Issue #1580: On most platforms, use a 'short' float repr: for a
4701 finite float x, repr(x) now outputs a string based on the shortest
4702 sequence of decimal digits that rounds to x. Previous behaviour was
4703 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004704 Another minor difference is that the new repr switches to
4705 exponential notation at 1e16 instead of the previous 1e17; this
4706 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004707
4708 There's a new sys attribute sys.float_repr_style, which takes
4709 the value 'short' to indicate that we're using short float repr,
4710 and 'legacy' if the short float repr isn't available for one
4711 reason or another.
4712
4713 The float repr change involves incorporating David Gay's 'perfect
4714 rounding' code into the Python core (it's in Python/dtoa.c). As a
4715 secondary consequence, all string-to-float and float-to-string
4716 conversions (including all float formatting operations) will be
4717 correctly rounded on these platforms.
4718
Georg Brandl5f90d792010-08-01 22:31:05 +00004719 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004720 this change does not apply.
4721

Mark Dickinson87ec0852009-02-09 17:15:59 +00005021- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5022 it now forces its argument to double before testing for infinity.
5023
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005024- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5025 returns a non-number type.
5026
Benjamin Peterson87618552009-02-08 15:00:52 +00005027- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonc008a172009-02-01 13:59:22 +00005029- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5030 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005031 the type definition cmpfunc. The tp_compare slot has been renamed
5032 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005034- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005035 were suppressing all exceptions. These include list() and bytearray().
5036
Mark Dickinson1124e712009-01-28 21:25:58 +00005037- Issue #4707: round(x, n) now returns an integer if x is an integer.
5038 Previously it returned a float.
5039
Antoine Pitroub52ec782009-01-25 16:34:23 +00005040- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5041 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5042 evaluation loop is compiled with a new dispatch mechanism which gives
5043 speedups of up to 20%, depending on the system, on various benchmarks.

5054
Mark Dickinson8055afd2009-01-17 10:04:45 +00005055- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005056 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005057
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005058- Issue #4935: The overflow checking code in the expandtabs() method common
5059 to str, bytes and bytearray could be optimized away by the compiler, letting
5060 the interpreter segfault instead of raising an error.
5061
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005062- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5063 __next__ method.
5064
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005065- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5066 function no longer attempt to call the __long__ slot to convert an object
5067 to an integer. Only the __int__ and __trunc__ slots are examined.

5072
Antoine Pitrouab868312009-01-10 15:40:25 +00005073- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5074 common cases are optimized thanks to a dedicated fast path and a moderate
5075 amount of loop unrolling.
5076
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005077- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5078 collecting the oldest generation) so that allocating lots of objects without
5079 destroying them does not show quadratic performance. Based on a proposal by
5080 Martin von Löwis at
5081 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5082
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005083- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005084 having been closed (for instance, a read() call could return some
5085 previously buffered data). Patch by Dmitry Vasiliev.
5086
Antoine Pitrou05608432009-01-09 18:53:14 +00005087- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5088 flag to work properly. Furthermore, when specifying -u, the text stdout
5089 and stderr streams have line-by-line buffering enabled (the default being
5090 to buffer arbitrary chunks of data).
5091
Raymond Hettinger35631532009-01-09 03:58:09 +00005092- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5093 instead of ints (reducing its size from 4 to 8 times thereby reducing
5094 Python's overall memory).
5095
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005096- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5097 an existing .py counterpart, override the co_filename attributes of all
5098 code objects if the original filename is obsolete (which can happen if the
5099 file has been renamed, moved, or if it is accessed through different paths).
5100 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5101
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005102- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5103 one byte. Also fixes the meaning of len() so that it returns the number of
5104 items, rather than the size in bytes.
5105
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005106- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005108- Issue #4747: When the terminal does not use utf-8, executing a script with
5109 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5110
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005111- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5119
Georg Brandlccc47b62008-12-28 11:44:14 +00005120- Issue #4759: None is now allowed as the first argument of

5122
Skip Montanaro80072cb2008-12-23 03:51:14 +00005123- Added test case to ensure attempts to read from a file opened for writing
5124 fail.

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005137- Issue #2173: When getting device encoding, check that return value of
5138 nl_langinfo is not the empty string. This was causing silent build
5139 failures on OS X.
5140
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005141- Issue #4597: Fixed several opcodes that weren't always propagating
5142 exceptions.
5143
5144- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005145 context manager returns a value that cannot be converted to a bool.
5146
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005147- Issue #4445: Replace "sizeof(PyBytesObject)" with
5148 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5149 bytes instances. On a typical machine this saves 3 bytes of memory
5150 (on average) per allocation of a bytes instance.
5151
Christian Heimesa872de52008-12-05 08:26:55 +00005152- Issue #4533: File read operation was dreadfully slow due to a slowly
5153 growing read buffer. Fixed by using the same growth rate algorithm as
5154 Python 2.x.
5155
Antoine Pitrou5504e892008-12-06 21:27:53 +00005156- Issue #4509: Various issues surrounding resize of bytearray objects to
5157 which there are buffer exports (e.g. memoryview instances).
5158
Georg Brandlf9734072008-12-07 15:30:06 +00005159- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5160 method on file objects with closefd=False. The file descriptor is still
5161 kept open but the file object behaves like a closed file. The ``FileIO``
5162 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005171- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5172 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5173 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5174 of using the replace error handler in PyUnicode_DecodeUTF8().
