Ned Deily657b2de2011-06-28 19:51:30 -0700548- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
549 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
550 interpreter process. This could cause failures in non-Distutils subprocesses
551 and was unreliable since tests or user programs could modify the interpreter
552 environment after Distutils set it. Instead, have Distutils set the the
553 deployment target only in the environment of each build subprocess. It is
554 still possible to globally override the default by setting
555 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
556 greater or equal to the default value, the value with which the interpreter

2757
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002758- Issue #10068: Global objects which have reference cycles with their module's
2759 dict are now cleared again. This causes issue #7140 to appear again.
2760
Victor Stinner257d38f2010-10-09 10:12:11 +00002761- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002762 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002763
Georg Brandl27a28582010-10-10 09:49:21 +00002764- ast.literal_eval() can now handle negative numbers. It is also a little more
2765 liberal in what it accepts without compromising the safety of the evaluation.
2766 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002767
Benjamin Peterson970d1882010-10-02 17:55:47 +00002768- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2769 result metaclasses can now be ABCs (see #9533).
2770
Victor Stinneraef57e32010-10-02 11:50:49 +00002771- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2772
Victor Stinner5593d8a2010-10-02 11:11:27 +00002773- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002774 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2775 32 bits wchar_t (eg. Linux in narrow build).

2781
Brett Cannon5305a992010-09-27 21:08:38 +00002782- Issue #7397: Mention that importlib.import_module() is probably what someone
2783 really wants to be using in __import__'s docstring.
2784
Georg Brandl27a28582010-10-10 09:49:21 +00002785- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2786 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002788- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002789 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002791- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2792
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002793- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2794 threads are still running. Instead, reinitialize the GIL on a second call to
2795 Py_Initialize().
2796
Georg Brandl27a28582010-10-10 09:49:21 +00002797- All SyntaxErrors now have a column offset and therefore a caret when the error
2798 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002799
Brett Cannonbc2eff32010-09-19 21:39:02 +00002800- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2801 module that was imported, but instead gets the module from sys.modules.
2802
Nick Coghlan37ee8502010-12-03 14:26:13 +00002803- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002804 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002805
Georg Brandl27a28582010-10-10 09:49:21 +00002806- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2807 with a non-empty format string. This is an effort to future-proof user
2808 code. If a derived class does not currently implement __format__ but later
2809 adds its own __format__, it would most likely break user code that had
2810 supplied a format string. This will be changed to a DeprecationWaring in
2811 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002812
Antoine Pitrou1df15362010-09-13 14:16:46 +00002813- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2814 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2815 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2816
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002817- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2818 functions from the libc caused the methods .upper() and lower() to become
2819 locale aware and created subtly wrong results.
2820
Georg Brandl27a28582010-10-10 09:49:21 +00002821- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2822 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002823
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002824- Issue #4617: Previously it was illegal to delete a name from the local
2825 namespace if it occurs as a free variable in a nested block. This limitation
2826 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2827
Georg Brandl27a28582010-10-10 09:49:21 +00002828- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2829 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2830 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2831 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002832
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002833- Issue #9757: memoryview objects get a release() method to release the
2834 underlying buffer (previously this was only done when deallocating the
2835 memoryview), and gain support for the context management protocol.
2836
Antoine Pitrou079ce542010-09-08 12:37:10 +00002837- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2838 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002854- Issue #4661: email can now parse bytes input and generate either converted
2855 7bit output or bytes output. Email version bumped to 5.1.0.
2856
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002857- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2862
Éric Araujo6108bf52010-10-04 23:52:37 +00002863- Issue #9042: Fix interaction of custom translation classes and caching in
2864 gettext.
2865
Éric Araujoef777bd2010-10-05 00:04:20 +00002866- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002867 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002868 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002869 replacement for old handle_accept() and avoids the user to call accept()
2870 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002893- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002894 retry the select() loop instead of bailing out. This is because select() can
2895 incorrectly report a socket as ready for reading (for example, if it received
2896 some data with an invalid checksum).

2941
Antoine Pitrou98b46702010-09-18 22:59:00 +00002942- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002943 non-blocking mode: they return None when an operation would block (instead of
2944 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002945
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002946- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
2947 another kind.
2948
Vinay Sajip19ec67a2010-09-17 18:57:36 +00002949- Issue #9441: logging has better coverage for rotating file handlers.
2950
Georg Brandl27a28582010-10-10 09:49:21 +00002951- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
Raymond Hettinger35c87f22010-09-16 19:10:17 +00002952
Georg Brandl27a28582010-10-10 09:49:21 +00002953- Issue #9854: The default read() implementation in io.RawIOBase now handles
2954 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002955
Georg Brandl27a28582010-10-10 09:49:21 +00002956- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2957 supporting the whole socket API (rather than the "raw" _socket.socket
2958 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002959
Georg Brandl27a28582010-10-10 09:49:21 +00002960- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2961 to match the corresponding socket methods.
Antoine Pitroua468adc2010-09-14 14:43:44 +00002962
Éric Araujod8c73c62011-03-21 03:15:22 +01002963- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002964 them handle recursive calls within the same thread.
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +00002965
Vinay Sajipaf9d10a2010-09-13 20:40:30 +00002966- logging: Enhanced HTTPHandler with secure and credentials initializers.
2967
Victor Stinnere797c162010-09-17 23:34:26 +00002968- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinnerccb706c2010-09-13 19:41:36 +00002969
Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002970- Issue #9837: The read() method of ZipExtFile objects (as returned by
2971 ZipFile.open()) could return more bytes than requested.
2972
Georg Brandl27a28582010-10-10 09:49:21 +00002973- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2974 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002975
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002976- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002977 it possible for the user to create self-referencing ordered dictionaries which
2978 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002979 approach of using weakref proxies so that reference cycles never get created
2980 in the first place.
2981
Victor Stinnercb043522010-09-10 23:49:04 +00002982- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2983 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002984 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002985
Georg Brandl27a28582010-10-10 09:49:21 +00002986- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2987 environment variable to set the filesystem encoding at Python startup.
2988 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2989 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002990
Georg Brandl27a28582010-10-10 09:49:21 +00002991- Issue #9410: Various optimizations to the pickle module, leading to speedups
2992 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2993 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002994
Georg Brandl27a28582010-10-10 09:49:21 +00002995- The pprint module now supports printing OrderedDicts in their given order
2996 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002997
Vinay Sajip121a1c42010-09-08 10:46:15 +00002998- Logging: Added QueueHandler class to facilitate logging usage with
2999 multiprocessing.
3000
Georg Brandl27a28582010-10-10 09:49:21 +00003001- Issue #9707: Rewritten reference implementation of threading.local which is
3002 friendlier towards reference cycles. This change is not normally visible
3003 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003004
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003005- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3006 still return the id of the parent process after it has exited. This process
3007 id may even have been reused by another unrelated process.
3008
Georg Brandl27a28582010-10-10 09:49:21 +00003009- Issue #9792: In case of connection failure, socket.create_connection() would
3010 swallow the exception and raise a new one, making it impossible to fetch the
3011 original errno, or to filter timeout errors. Now the original error is
3012 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00003013
Georg Brandl27a28582010-10-10 09:49:21 +00003014- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3015 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3016 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003017
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003018- Updates to the random module:
3019
Georg Brandl27a28582010-10-10 09:49:21 +00003020 * Document which parts of the module are guaranteed to stay the same across
3021 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003022
Georg Brandl27a28582010-10-10 09:49:21 +00003023 * Update the seed() method to use all of the bits in a string instead of just
3024 the hash value. This makes better use of the seed value and assures the
3025 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003026
Georg Brandl27a28582010-10-10 09:49:21 +00003027 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3028 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3029 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003030
3031 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00003036- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
3037 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3038 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00003039
Georg Brandl27a28582010-10-10 09:49:21 +00003040- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
3041 their contents without duplicating them. The view is both readable and
3042 writable.
Antoine Pitrou972ee132010-09-06 18:48:21 +00003043
Brian Curtin62857742010-09-06 17:07:27 +00003044- Issue #7566: Implement os.path.sameopenfile for Windows.
3045
Antoine Pitrou0d739d72010-09-05 23:01:12 +00003046- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003047 unsupported operation is attempted (for example, writing to a file open only
3048 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00003049
Gregory P. Smith13b55292010-09-06 08:30:23 +00003050- hashlib has two new constant attributes: algorithms_guaranteed and
3051 algorithms_avaiable that respectively list the names of hash algorithms
3052 guaranteed to exist in all Python implementations and the names of hash
3053 algorithms available in the current process.
3054
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003055- A new package ``concurrent.futures`` as defined by PEP 3148.

3061
Benjamin Peterson568867a2010-09-11 16:02:03 +00003062- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
3063 PySequence_DelSlice when the object doesn't have any mapping operations
3064 defined.

Georg Brandl27a28582010-10-10 09:49:21 +00003069- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
3070 wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
3071 and the interpreter under test.

Georg Brandl649971e2010-09-05 17:06:50 +00003145- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3146 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
3147 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00003148
Brett Cannonef0e6c32010-09-04 18:24:04 +00003149- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Georg Brandl649971e2010-09-05 17:06:50 +00003158- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3159 now removed, since their effect was inexistent in 3.x (the default encoding is

3164
Georg Brandl649971e2010-09-05 17:06:50 +00003165- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3166 platforms. Previously, it inlined only when using Microsoft Visual C.

3180
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00003181- Issue #5127: The C functions that access the Unicode Database now accept and
3182 return characters from the full Unicode range, even on narrow unicode builds
3183 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3184 in Python is that unicodedata.numeric() now returns the correct value for

Ezio Melotti57221d02010-07-01 07:32:02 +00003565- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003566 start byte and the continuation byte(s) are now considered invalid, instead of
3567 the number of bytes specified by the start byte. E.g.:
3568 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3569 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3570 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3571 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003601- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003602 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003614- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3615 TypeError instead of giving a DeprecationWarning when a float is parsed using
3616 the 'L' code (for long long). (All other integer codes already raise
3617 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003618
Victor Stinner600d3be2010-06-10 12:00:55 +00003619- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3621 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3622
Georg Brandl62069d32010-07-31 08:56:11 +00003623- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3624 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003625
3626- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003627 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003628 like bytearray.
3629
Georg Brandl62069d32010-07-31 08:56:11 +00003630- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003631 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003638- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3639 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3640 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3641 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003642
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003643- Issue #8748: Fix two issues with comparisons between complex and integer
3644 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003645 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3646 (2) The comparison raised an OverflowError for large integers, leading to

Georg Brandl62069d32010-07-31 08:56:11 +00003778 where the right hand operand is a set of constants, by turning the set into a
3779 frozenset and pre-building it as a constant. The comparison operation is made
3780 against the constant instead of building a new set each time it is executed (a
3781 similar optimization already existed which turned a list of constants into a

3953
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003954- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3955 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3978 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3979 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003980 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003990- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3991 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3992 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4009 gives improved memory leak detection when running under Valgrind, while taking
4010 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004087 applications that use a lot of regular expressions and limits the impact of
4088 the performance hit anytime the cache is exceeded.

Victor Stinnerd17f2192010-08-15 09:56:07 +00004334- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00004335 (instead of replace in read mode or strict in write mode).
Victor Stinnerde629d42010-05-05 21:43:57 +00004336
Barry Warsaw83d89982010-05-05 16:18:31 +00004337- Issue #7755: Use an unencumbered audio file for tests.

4340 and any children created using ``os.fork`` on MacOS X 10.6.
Ronald Oussorenac764d32010-05-05 15:32:33 +00004341
Georg Brandl62069d32010-07-31 08:56:11 +00004342- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4343 operation raises multiple signals and more than one of those signals is
4344 trapped, the specification determines the order in which the signals should be
4345 handled. In many cases this order wasn't being followed, leading to the wrong
4346 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00004347
Antoine Pitrou6be88762010-05-03 16:48:20 +00004348- Issue #7865: The close() method of :mod:`io` objects should not swallow
Georg Brandl62069d32010-07-31 08:56:11 +00004349 exceptions raised by the implicit flush(). Also qensure that calling close()
4350 several times is supported. Patch by Pascal Chambon.

4353 gc.DEBUG_STATS.
4354
Georg Brandl62069d32010-07-31 08:56:11 +00004355- Issue #8354: The siginterrupt setting is now preserved for all signals, not
4356 just SIGCHLD.
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +00004357

Georg Brandl62069d32010-07-31 08:56:11 +00004380- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4381 the method could block indefinitely if called just before the event loop
4382 started running. This also fixes the occasional freezes witnessed in
4383 test_httpservers.
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00004384
Georg Brandl62069d32010-07-31 08:56:11 +00004385- Issue #8524: When creating an SSL socket, the timeout value of the original
4386 socket wasn't retained (instead, a socket with a positive timeout would be
4387 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004388
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004389- Issue #5103: SSL handshake would ignore the socket timeout and block
4390 indefinitely if the other end didn't respond.
4391
Georg Brandl62069d32010-07-31 08:56:11 +00004392- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4393 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004394
Georg Brandl62069d32010-07-31 08:56:11 +00004395- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Victor Stinner349fd522010-04-23 10:56:17 +00004403
Georg Brandl62069d32010-07-31 08:56:11 +00004404- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4405 string "python" as the *ident*. openlog() arguments are all optional and
4406 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004407
Georg Brandl62069d32010-07-31 08:56:11 +00004408- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4409 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004410 wanting to continue using the socket in clear-text mode, by disabling
4411 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
4412
Antoine Pitrou7062db82010-04-22 13:30:10 +00004413- Issue #8496: make mailcap.lookup() always return a list, rather than an

4420 extension, such that verification of some SSL certificates doesn't fail
4421 because of an "unknown algorithm".
Antoine Pitroufec12ff2010-04-21 19:46:23 +00004422

4445 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
4446
Victor Stinner0e59cc32010-04-16 23:49:32 +00004447- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

4459
Georg Brandl62069d32010-07-31 08:56:11 +00004460- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004461 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004462 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004463
Victor Stinner485fb562010-04-13 11:07:24 +00004464- Issue #8383: pickle and pickletools use surrogatepass error handler when
4465 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00004466 Python 2.x and 3.x.
Victor Stinner485fb562010-04-13 11:07:24 +00004467
R. David Murrayb2416e52010-04-12 16:58:02 +00004468- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004469 filename and date, conforming to the 'standards' they were originally designed
4470 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00004471
R. David Murrayef3d6bd2010-04-12 14:48:58 +00004472- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Georg Brandl62069d32010-07-31 08:56:11 +00004483 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4484 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00004485
Raymond Hettingerc50846a2010-04-05 18:56:31 +00004486- Add functools.total_ordering() and functools.cmp_to_key().
4487
Georg Brandl62069d32010-07-31 08:56:11 +00004488- Issue #8257: The Decimal construct now accepts a float instance directly,
4489 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004490
4491 >>> Decimal(1.1)
4492 Decimal('1.100000000000000088817841970012523233890533447265625')
4493

Georg Brandl62069d32010-07-31 08:56:11 +00004497- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4498 InvalidOperation instead of returning False. (Comparisons involving a quiet
4499 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4500 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004501
Georg Brandl62069d32010-07-31 08:56:11 +00004502- Issue #2531: Comparison operations between floats and Decimal instances now
4503 return a result based on the numeric values of the operands; previously they
4504 returned an arbitrary result based on the relative ordering of id(float) and
4505 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4506 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004507
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004508- Added a subtract() method to collections.Counter().
4509
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004510- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004511 argument `-` which tells it to read files to compile from stdin. Each line is
4512 read on demand and the named file is compiled immediately. (Original patch by
4513 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004514
Florent Xicluna806d8cf2010-03-30 19:34:18 +00004515- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4516 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004517 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

4520 Fractions instance now raise TypeError instead of returning True/False. This
4521 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4522 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004524- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Georg Brandl62069d32010-07-31 08:56:11 +00004532 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4533 silenced.

Antoine Pitrou3c0fac22010-03-26 19:36:14 +00004538- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4539 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4540 reads and writes are always retried by OpenSSL itself.

4566 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4567 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004569- subprocess.Popen now has restore_signals and start_new_session features. The
4570 default of restore_signals=True is a new behavior compared to earlier Python
4571 versions. This means that signals such as SIGPIPE are not ignored by default
4572 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004849 default when instantiating a `threading.RLock` object. This makes recursive
4850 locks as fast as regular non-recursive locks (previously, they were slower by
4851 10x to 15x).

Mark Dickinsonfa41e602010-09-28 07:22:27 +00005060- Issue #9959: Tweak formula used for computing math.log of an integer,
5061 making it marginally more accurate for exact powers of 2.

5064
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005065- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005066 compared to other unix systems. In particular, os.getgroups() does not reflect
5067 any changes made using os.setgroups() but basicly always returns the same
5068 information as the id command. os.getgroups() can now return more than 16
5069 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005070

Benjamin Petersonf751bc92010-07-02 13:46:42 +00005091- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
5092 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00005093
Georg Brandl62069d32010-07-31 08:56:11 +00005094- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5095 Prior to this change, timezone adjustment in utctimetuple() could produce
5096 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5097 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00005098
Georg Brandl62069d32010-07-31 08:56:11 +00005099- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5100 directive. When the ``%z`` directive is present in the format string, an
5101 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5102 ``datetime.timezone`` instance constructed from the parsed offset. If both
5103 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5104 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005105
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005106- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005107 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5108 ``datetime.timezone``, return fixed name and UTC offset from their
5109 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5110 returns ``None``. A class attribute, ``utc`` contains an instance
5111 representing the UTC timezone. Original patch by Rafe Kaplan.

5121 curses module must be linked against ncurses as well. Otherwise it is not safe
5122 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00005123

Georg Brandl62069d32010-07-31 08:56:11 +00005127- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5128 with an improved 'binary-split' algorithm that uses fewer multiplications and
5129 allows many of the multiplications to be performed using plain C integer
5130 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5131 arguments.

5134 overflow checks in the audioop module.
5135
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005136- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5137 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005138 the result is now always correctly rounded, and is equivalent to ``td /
5139 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005140
Georg Brandl62069d32010-07-31 08:56:11 +00005141- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

5146
Mark Dickinsonc5935772010-04-03 15:54:36 +00005147- Issue #8300: When passing a non-integer argument to struct.pack with any
5148 integer format code, struct.pack first attempts to convert the non-integer
5149 using its __index__ method. If that method is non-existent or raises
5150 TypeError it goes on to try the __int__ method, as described below.
5151
Matthias Klosea8349752010-03-15 13:25:28 +00005152- Issue #8142: Update libffi to the 3.0.9 release.

5531 are always None now.
5532
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005533- Issue #6137: The pickle module now translates module names when loading
5534 or dumping pickles with a 2.x-compatible protocol, in order to make data
5535 sharing and migration easier. This behaviour can be disabled using the
5536 new `fix_imports` optional argument.

Eric Smith41669ca2009-05-23 14:23:22 +00005590- Issue #6089: Fixed str.format with certain invalid field specifiers
5591 that would raise SystemError.
5592
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005593- Issue #5982: staticmethod and classmethod now expose the wrapped
5594 function with __func__.
5595
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005596- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005599- Issue #5829: complex("1e500") no longer raises OverflowError. This
5600 makes it consistent with float("1e500") and interpretation of real
5601 and imaginary literals.
5602
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005603- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005607- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5608 (1) inf and nan strings with trailing whitespace were incorrectly
5609 rejected; (2) parsing of strings representing infinities and nans
5610 was locale aware; and (3) the interpretation of fromhex('-nan')
5611 didn't match that of float('-nan').

Raymond Hettinger089ba7f2009-05-27 00:38:24 +00005626- collections.namedtuple() was not working with the following field
5627 names: cls, self, tuple, itemgetter, and property.
5628
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005629- In unittest, using a skipping decorator on a class is now equivalent to
5630 skipping every test on the class. The ClassTestSuite class has been removed.
5631
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005632- Issue #6050: Don't fail extracting a directory from a zipfile if
5633 the directory already exists.
5634
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005635- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5636 than an int, which makes some operations possible under 64-bit Linux (e.g.
5637 DN_MULTISHOT with F_NOTIFY).
5638
Antoine Pitrou716c4442009-05-23 19:04:03 +00005639- Issue #5761: Add the name of the underlying file to the repr() of various
5640 IO objects.
5641
R. David Murraycaa27b72009-05-23 18:49:56 +00005642- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5643 by Musashi Tamura, tests by Marcin Bachry.
5644
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005645- Issue #1983: Fix functions taking or returning a process identifier to use
5646 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5647 a process identifier type wider than the standard C integer type.
5648
R. David Murray87e20742009-05-23 01:30:26 +00005649- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5660
Antoine Pitroue4501852009-05-14 18:55:55 +00005661- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5662 library. This means, for example, that opening an UTF-16 text file in
5663 append mode doesn't add a BOM at the end of the file if the file isn't
5664 empty.
5665
R. David Murray74b89242009-05-13 17:33:03 +00005666- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5667 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5668 corrects a pydoc regression.
5669
Georg Brandl5f90d792010-08-01 22:31:05 +00005670- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005671 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00005703- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005704 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005712*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005713
5714Core and Builtins
5715-----------------
5716
Mark Dickinson865e01a2009-05-07 16:37:01 +00005717- Issue #5914: Add new C API function PyOS_string_to_double, and
5718 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5719
Eric Smith741191f2009-05-06 13:08:15 +00005720- Issue #3382: float.__format__, complex.__format__, and %-formatting
5721 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5722 affects nan -> NAN and inf -> INF.
5723
Mark Hammond5a607a32009-05-06 08:04:54 +00005724- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5725 in all operations, including splitdrive, split, etc. splitunc() now issues
5726 a PendingDeprecation warning.
5727
Eric Smith63376222009-05-05 14:04:18 +00005728- Issue #5920: For float.__format__, change the behavior with the
5729 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5730 to be like 'g' but with at least one decimal point and with a
5731 default precision of 12. Previously, the behavior the same but with
5732 a default precision of 6. This more closely matches str(), and
5733 reduces surprises when adding alignment flags to the empty
5734 presentation type. This also affects the new complex.__format__ in
5735 the same way.
5736
Martin v. Löwis011e8422009-05-05 04:43:17 +00005737- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5738
R. David Murrayb18500d2009-05-04 22:59:07 +00005739- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5740 shadowed by classtype's, even if it was None. property now
5741 inserts the __doc__ into the subclass instance __dict__.
5742
Antoine Pitrou244651a2009-05-04 18:56:13 +00005743- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5744 sequences. Patch by Nick Barnes and Victor Stinner.
5745
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005746- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005747
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005748- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5749 received a new method, detach(). detach() disconnects the underlying stream
5750 from the buffer or text IO and returns it.
5751
Mark Dickinson33841c32009-05-01 15:37:04 +00005752- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5753 floats with absolute value over 1e50. Also remove length
5754 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5755 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005756
Eric Smith741191f2009-05-06 13:08:15 +00005757- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005758 format(complex(1, 2./3), '.5') now produces a sensible result.
5759
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005760- Issue #5864: Fix empty format code formatting for floats so that it
5761 never gives more than the requested number of significant digits.
5762
Eric Smith6dc46f52009-04-27 20:39:49 +00005763- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5764 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5765
Eric Smithcc32a112009-04-26 21:35:14 +00005766- Issue #5835: Deprecate PyOS_ascii_formatd.
5767
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005768- Issue #4971: Fix titlecase for characters that are their own
5769 titlecase, but not their own uppercase.
5770
Benjamin Peterson193152c2009-04-25 01:08:45 +00005771- Issue #5283: Setting __class__ in __del__ caused a segfault.
5772
Mark Dickinsonad476da2009-04-23 19:14:16 +00005773- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5774 z involves nans, infs or negative zeros.
5775
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005776- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005777
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005778- Issue #1869 (and many duplicates): make round(x, n) correctly
5779 rounded for a float x, by using the decimal <-> binary conversions
5780 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5781 consistently agrees with format(x, '.2f').
5782
Benjamin Petersonae937c02009-04-18 20:54:08 +00005783- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5784 some builtin types.
5785
Eric Smith0923d1d2009-04-16 20:16:10 +00005786- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5787
Eric Smith35e84722009-04-16 20:21:28 +00005788- Issue #5515: str.format() type 'n' combined with commas and leading
5789 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005790
5791- Implement PEP 378, Format Specifier for Thousands Separator, for
5792 floats.
5793
Mark Dickinson3370cce2009-04-17 22:40:53 +00005794- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005795 1e11, not 1e12. This avoids printing 13 significant digits in
5796 situations where only 12 of them are correct. Example problem
5797 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5798 long time.)
5799
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005800- Issue #1580: On most platforms, use a 'short' float repr: for a
5801 finite float x, repr(x) now outputs a string based on the shortest
5802 sequence of decimal digits that rounds to x. Previous behaviour was
5803 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005804 Another minor difference is that the new repr switches to
5805 exponential notation at 1e16 instead of the previous 1e17; this
5806 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005807
5808 There's a new sys attribute sys.float_repr_style, which takes
5809 the value 'short' to indicate that we're using short float repr,
5810 and 'legacy' if the short float repr isn't available for one
5811 reason or another.
5812
5813 The float repr change involves incorporating David Gay's 'perfect
5814 rounding' code into the Python core (it's in Python/dtoa.c). As a
5815 secondary consequence, all string-to-float and float-to-string
5816 conversions (including all float formatting operations) will be
5817 correctly rounded on these platforms.

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005820 this change does not apply.

5823
Georg Brandlabc38772009-04-12 15:51:51 +00005824- The string.maketrans() function is deprecated; there is a new static method
5825 maketrans() on the bytes and bytearray classes. This removes confusion about
5826 the types string.maketrans() is supposed to work with, and mirrors the
5827 methods available on the str class.

6108
Eric Smith5e5c0db2009-02-20 14:25:03 +00006109- Issue #5247: Improve error message when unknown format codes are
6110 used when using str.format() with str, int, and float arguments.
6111
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006112- Issue #5249: time.strftime returned malformed string when format string
6113 contained non ascii character on windows.
6114
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006115- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6116 source has already been decoded into str.
6117
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006118- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6119 rotating the object pointer by 4 bits to the right.
6120
Mark Dickinson87ec0852009-02-09 17:15:59 +00006121- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6122 it now forces its argument to double before testing for infinity.
6123
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006124- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6125 returns a non-number type.
6126
Benjamin Peterson87618552009-02-08 15:00:52 +00006127- Issue #5182: Removed memoryview.__str__.
6128
Mark Dickinsonc008a172009-02-01 13:59:22 +00006129- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6130 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006131 the type definition cmpfunc. The tp_compare slot has been renamed
6132 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006133
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006134- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006135 were suppressing all exceptions. These include list() and bytearray().
6136
Mark Dickinson1124e712009-01-28 21:25:58 +00006137- Issue #4707: round(x, n) now returns an integer if x is an integer.
6138 Previously it returned a float.
6139
Antoine Pitroub52ec782009-01-25 16:34:23 +00006140- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6141 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6142 evaluation loop is compiled with a new dispatch mechanism which gives
6143 speedups of up to 20%, depending on the system, on various benchmarks.
6144
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006145- Issue #4874: Most builtin decoders now reject unicode input.

6153 optional module state data.
6154
Mark Dickinson8055afd2009-01-17 10:04:45 +00006155- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006156 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006157
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006158- Issue #4935: The overflow checking code in the expandtabs() method common
6159 to str, bytes and bytearray could be optimized away by the compiler, letting
6160 the interpreter segfault instead of raising an error.
6161
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006162- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6163 __next__ method.
6164
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006165- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6166 function no longer attempt to call the __long__ slot to convert an object
6167 to an integer. Only the __int__ and __trunc__ slots are examined.
6168
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006169- Issue #4893: Use NT threading on CE.
6170

6172
Antoine Pitrouab868312009-01-10 15:40:25 +00006173- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6174 common cases are optimized thanks to a dedicated fast path and a moderate
6175 amount of loop unrolling.
6176
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006177- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6178 collecting the oldest generation) so that allocating lots of objects without
6179 destroying them does not show quadratic performance. Based on a proposal by
6180 Martin von Löwis at
6181 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6182
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006183- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006184 having been closed (for instance, a read() call could return some
6185 previously buffered data). Patch by Dmitry Vasiliev.
6186
Antoine Pitrou05608432009-01-09 18:53:14 +00006187- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6188 flag to work properly. Furthermore, when specifying -u, the text stdout
6189 and stderr streams have line-by-line buffering enabled (the default being
6190 to buffer arbitrary chunks of data).
6191
Raymond Hettinger35631532009-01-09 03:58:09 +00006192- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6193 instead of ints (reducing its size from 4 to 8 times thereby reducing
6194 Python's overall memory).
6195
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006196- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6197 an existing .py counterpart, override the co_filename attributes of all
6198 code objects if the original filename is obsolete (which can happen if the
6199 file has been renamed, moved, or if it is accessed through different paths).
6200 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6201
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006202- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6203 one byte. Also fixes the meaning of len() so that it returns the number of
6204 items, rather than the size in bytes.
6205
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006206- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6207
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006208- Issue #4747: When the terminal does not use utf-8, executing a script with
6209 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6210
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006211- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6212 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006213
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006214- Issue #3680: Reference cycles created through a dict, set or deque iterator
6215 did not get collected.
6216
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006217- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6218 where the tp_hash and tp_dict slots are both NULL.
6219
Georg Brandlccc47b62008-12-28 11:44:14 +00006220- Issue #4759: None is now allowed as the first argument of
6221 bytearray.translate(). It was always allowed for bytes.translate().
6222
Skip Montanaro80072cb2008-12-23 03:51:14 +00006223- Added test case to ensure attempts to read from a file opened for writing
6224 fail.
6225
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006226- Issue #3106: Speedup some comparisons (str/str and int/int).

6229 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6230
Antoine Pitrou621601a2008-12-17 23:18:19 +00006231- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6232 print elapsed times, not only when some objects are uncollectable /
6233 unreachable. Original patch by Neil Schemenauer.
6234
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006235- Issue #3439: Add a bit_length method to int.
6236
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006237- Issue #2173: When getting device encoding, check that return value of
6238 nl_langinfo is not the empty string. This was causing silent build
6239 failures on OS X.
6240
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006241- Issue #4597: Fixed several opcodes that weren't always propagating
6242 exceptions.
6243
6244- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006245 context manager returns a value that cannot be converted to a bool.
6246
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006247- Issue #4445: Replace "sizeof(PyBytesObject)" with
6248 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6249 bytes instances. On a typical machine this saves 3 bytes of memory
6250 (on average) per allocation of a bytes instance.
6251
Christian Heimesa872de52008-12-05 08:26:55 +00006252- Issue #4533: File read operation was dreadfully slow due to a slowly
6253 growing read buffer. Fixed by using the same growth rate algorithm as
6254 Python 2.x.
6255
Antoine Pitrou5504e892008-12-06 21:27:53 +00006256- Issue #4509: Various issues surrounding resize of bytearray objects to
6257 which there are buffer exports (e.g. memoryview instances).
6258
Georg Brandlf9734072008-12-07 15:30:06 +00006259- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6260 method on file objects with closefd=False. The file descriptor is still
6261 kept open but the file object behaves like a closed file. The ``FileIO``
6262 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006263
Antoine Pitroubc420402008-12-07 20:14:49 +00006264- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6265 larger than 1.

6270
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006271- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6272 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6273 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6274 of using the replace error handler in PyUnicode_DecodeUTF8().
