684 environment after Distutils set it. Instead, have Distutils set the the

686 still possible to globally override the default by setting

688 greater or equal to the default value, the value with which the interpreter
689 was built.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001529- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001530 continuation line in the formatted value has no leading white space and looks
1531 like a header. Since Generator uses Header to format all headers, this check
1532 is made for all headers in any serialized message at serialization time. This
1533 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001534
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001535- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

1540
R. David Murray92532142011-01-07 23:25:30 +00001541- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001542 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001543 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001544
Éric Araujof0ab5d62011-05-29 03:43:59 +02001545- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001546 rfc2047-encoding header values with embedded newlines, leaving them without
1547 folding whitespace. It now uses the continuation_ws, as it does for
1548 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001549
Victor Stinner3ec899f2011-01-08 16:37:47 +00001550- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1551 time.asctime(), time.ctime() and time.strftime() functions will now format
1552 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1553 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1554 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1555 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001556
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001557- Issue #7858: Raise an error properly when os.utime() fails under Windows

1562
Victor Stinner4bd81722011-01-06 00:49:38 +00001563- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1564 compilation (if the input is a string).
1565
Antoine Pitrou600232b2011-01-05 21:03:42 +00001566- Issue #7995: When calling accept() on a socket with a timeout, the returned

2531
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002532- Issue #10068: Global objects which have reference cycles with their module's
2533 dict are now cleared again. This causes issue #7140 to appear again.
2534
Victor Stinner257d38f2010-10-09 10:12:11 +00002535- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002536 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002537
Georg Brandl27a28582010-10-10 09:49:21 +00002538- ast.literal_eval() can now handle negative numbers. It is also a little more
2539 liberal in what it accepts without compromising the safety of the evaluation.
2540 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002541
Benjamin Peterson970d1882010-10-02 17:55:47 +00002542- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2543 result metaclasses can now be ABCs (see #9533).
2544
Victor Stinneraef57e32010-10-02 11:50:49 +00002545- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2546
Victor Stinner5593d8a2010-10-02 11:11:27 +00002547- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002548 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2549 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002550
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002551- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002552 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002553
Victor Stinner137c34c2010-09-29 10:25:54 +00002554- Issue #9979: Create function PyUnicode_AsWideCharString().
2555
Brett Cannon5305a992010-09-27 21:08:38 +00002556- Issue #7397: Mention that importlib.import_module() is probably what someone
2557 really wants to be using in __import__'s docstring.
2558
Georg Brandl27a28582010-10-10 09:49:21 +00002559- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2560 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002561
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002562- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002563 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002564
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002565- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2566
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002567- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2568 threads are still running. Instead, reinitialize the GIL on a second call to
2569 Py_Initialize().
2570
Georg Brandl27a28582010-10-10 09:49:21 +00002571- All SyntaxErrors now have a column offset and therefore a caret when the error
2572 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002573
Brett Cannonbc2eff32010-09-19 21:39:02 +00002574- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2575 module that was imported, but instead gets the module from sys.modules.
2576
Nick Coghlan37ee8502010-12-03 14:26:13 +00002577- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002578 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002579
Georg Brandl27a28582010-10-10 09:49:21 +00002580- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2581 with a non-empty format string. This is an effort to future-proof user
2582 code. If a derived class does not currently implement __format__ but later
2583 adds its own __format__, it would most likely break user code that had
2584 supplied a format string. This will be changed to a DeprecationWaring in
2585 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002586
Antoine Pitrou1df15362010-09-13 14:16:46 +00002587- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2588 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2589 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2590
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002591- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2592 functions from the libc caused the methods .upper() and lower() to become
2593 locale aware and created subtly wrong results.
2594
Georg Brandl27a28582010-10-10 09:49:21 +00002595- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2596 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002597
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002598- Issue #4617: Previously it was illegal to delete a name from the local
2599 namespace if it occurs as a free variable in a nested block. This limitation
2600 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2601
Georg Brandl27a28582010-10-10 09:49:21 +00002602- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2603 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2604 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2605 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002606
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002607- Issue #9757: memoryview objects get a release() method to release the
2608 underlying buffer (previously this was only done when deallocating the
2609 memoryview), and gain support for the context management protocol.
2610
Antoine Pitrou079ce542010-09-08 12:37:10 +00002611- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2612 thread-local storage key.

2622
2623- Issue #1718574: Fix options that were supposed to accept arguments but did
2624 not in build_clib.
2625
Antoine Pitroudbec7802010-10-10 09:37:12 +00002626- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2627
R. David Murray96fd54e2010-10-08 15:55:28 +00002628- Issue #4661: email can now parse bytes input and generate either converted
2629 7bit output or bytes output. Email version bumped to 5.1.0.
2630
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002631- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2632 verification for higher-level protocols.
2633
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002634- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2635 after the file is closed. Patch by Jeffrey Finkelstein.
2636
Éric Araujo6108bf52010-10-04 23:52:37 +00002637- Issue #9042: Fix interaction of custom translation classes and caching in
2638 gettext.
2639
Éric Araujoef777bd2010-10-05 00:04:20 +00002640- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002641 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002642 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002643 replacement for old handle_accept() and avoids the user to call accept()
2644 directly.
2645
Lars Gustäbel331b8002010-10-04 15:18:47 +00002646- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2647 gname field.
2648
Georg Brandl27a28582010-10-10 09:49:21 +00002649- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2650 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002651
R. David Murray5397e862010-10-02 15:58:26 +00002652- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2653 characters that appear inside quoted strings in email addresses.
2654
Georg Brandl27a28582010-10-10 09:49:21 +00002655- Issue #10004: quoprimime no longer generates a traceback when confronted with
2656 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002657
Georg Brandl27a28582010-10-10 09:49:21 +00002658- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2659 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002660
Georg Brandl27a28582010-10-10 09:49:21 +00002661- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2662 conforms to the philosophy of bytes and unicode separation in Python 3. A
2663 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002664
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002665- Issue #9962: GzipFile now has the peek() method.
2666
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002667- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002668 retry the select() loop instead of bailing out. This is because select() can
2669 incorrectly report a socket as ready for reading (for example, if it received
2670 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002671
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002672- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002674- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002675 received. Now sendall() properly calls signal handlers if necessary, and
2676 retries sending if these returned successfully, including on sockets with a
2677 timeout.

2715
Antoine Pitrou98b46702010-09-18 22:59:00 +00002716- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002717 non-blocking mode: they return None when an operation would block (instead of
2718 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002719
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002720- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

2728 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002729
Georg Brandl27a28582010-10-10 09:49:21 +00002730- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2731 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002750- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002751 it possible for the user to create self-referencing ordered dictionaries which
2752 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002753 approach of using weakref proxies so that reference cycles never get created
2754 in the first place.
2755
Victor Stinnercb043522010-09-10 23:49:04 +00002756- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2757 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002758 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002759
Georg Brandl27a28582010-10-10 09:49:21 +00002760- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2761 environment variable to set the filesystem encoding at Python startup.
2762 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2763 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002764
Georg Brandl27a28582010-10-10 09:49:21 +00002765- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00002772- Logging: Added QueueHandler class to facilitate logging usage with
2773 multiprocessing.
2774
Georg Brandl27a28582010-10-10 09:49:21 +00002775- Issue #9707: Rewritten reference implementation of threading.local which is
2776 friendlier towards reference cycles. This change is not normally visible
2777 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002778
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002779- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2780 still return the id of the parent process after it has exited. This process
2781 id may even have been reused by another unrelated process.
2782
Georg Brandl27a28582010-10-10 09:49:21 +00002783- Issue #9792: In case of connection failure, socket.create_connection() would
2784 swallow the exception and raise a new one, making it impossible to fetch the
2785 original errno, or to filter timeout errors. Now the original error is
2786 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002787
Georg Brandl27a28582010-10-10 09:49:21 +00002788- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2789 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2790 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002791
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002792- Updates to the random module:
2793
Georg Brandl27a28582010-10-10 09:49:21 +00002794 * Document which parts of the module are guaranteed to stay the same across
2795 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002797 * Update the seed() method to use all of the bits in a string instead of just
2798 the hash value. This makes better use of the seed value and assures the
2799 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002801 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2802 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2803 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002804
2805 * Improved documentation of arguments to randrange(). Issue #9379.

2811 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2812 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002824- hashlib has two new constant attributes: algorithms_guaranteed and
2825 algorithms_avaiable that respectively list the names of hash algorithms
2826 guaranteed to exist in all Python implementations and the names of hash
2827 algorithms available in the current process.
2828
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002829- A new package ``concurrent.futures`` as defined by PEP 3148.

Ezio Melotti57221d02010-07-01 07:32:02 +00003339- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003340 start byte and the continuation byte(s) are now considered invalid, instead of
3341 the number of bytes specified by the start byte. E.g.:
3342 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3343 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3344 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3345 returned a single u'\ufffd'.

3374
Georg Brandl62069d32010-07-31 08:56:11 +00003375- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test

3389 TypeError instead of giving a DeprecationWarning when a float is parsed using
3390 the 'L' code (for long long). (All other integer codes already raise
3391 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00003401 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

Georg Brandl62069d32010-07-31 08:56:11 +00003404- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

3418 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003419 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3420 (2) The comparison raised an OverflowError for large integers, leading to
3421 unpredictable exceptions when combining integers and complex objects in sets
3422 or dicts.

3726 `va_copy`, but available on all python platforms.
3727
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003728- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3729 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3730 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003740- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003741 function declaration, which was kept for backwards compatibility reasons, is
3742 now removed (the macro was introduced in 1997!).

3752 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3753 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003754 to match the behaviour of the other integer format codes.
3755

Georg Brandl62069d32010-07-31 08:56:11 +00003764- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3765 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3766 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3783 gives improved memory leak detection when running under Valgrind, while taking
3784 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003861 applications that use a lot of regular expressions and limits the impact of
3862 the performance hit anytime the cache is exceeded.

3875 module is renamed to `_datetime` and if available, overrides all classes
3876 defined in datetime with fast C impementation. Python implementation is based
3877 on the original python prototype for the datetime module by Tim Peters with
3878 minor modifications by the PyPy project. The test suite now tests `datetime`
3879 module with and without `_datetime` acceleration using the same test cases.

4094 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
4095 file system encoding with the surrogateescape error handler (instead of
4096 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

4099
Georg Brandl62069d32010-07-31 08:56:11 +00004100- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
4101 messages when accessing undefined class attributes because of the cheap
4102 inheritance with the underlying socket object. The cheap inheritance has been
4103 deprecated.

4106 Patch by Tres Seaver.
4107
Victor Stinnerd17f2192010-08-15 09:56:07 +00004108- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00004109 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00004116- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4117 operation raises multiple signals and more than one of those signals is
4118 trapped, the specification determines the order in which the signals should be
4119 handled. In many cases this order wasn't being followed, leading to the wrong
4120 Python exception being raised.

4128
Georg Brandl62069d32010-07-31 08:56:11 +00004129- Issue #8354: The siginterrupt setting is now preserved for all signals, not

4153
Georg Brandl62069d32010-07-31 08:56:11 +00004154- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4155 the method could block indefinitely if called just before the event loop
4156 started running. This also fixes the occasional freezes witnessed in
4157 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00004159- Issue #8524: When creating an SSL socket, the timeout value of the original
4160 socket wasn't retained (instead, a socket with a positive timeout would be
4161 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004162
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004163- Issue #5103: SSL handshake would ignore the socket timeout and block
4164 indefinitely if the other end didn't respond.
4165
Georg Brandl62069d32010-07-31 08:56:11 +00004166- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4167 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00004178- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4179 string "python" as the *ident*. openlog() arguments are all optional and
4180 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004181
Georg Brandl62069d32010-07-31 08:56:11 +00004182- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4183 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004184 wanting to continue using the socket in clear-text mode, by disabling
4185 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004235 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004236 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00004242- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004243 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00004271- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4272 InvalidOperation instead of returning False. (Comparisons involving a quiet
4273 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4274 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004275
Georg Brandl62069d32010-07-31 08:56:11 +00004276- Issue #2531: Comparison operations between floats and Decimal instances now
4277 return a result based on the numeric values of the operands; previously they
4278 returned an arbitrary result based on the relative ordering of id(float) and
4279 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4280 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004281
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004282- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004284- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004285 argument `-` which tells it to read files to compile from stdin. Each line is

4294 Fractions instance now raise TypeError instead of returning True/False. This
4295 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4296 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004840 compared to other unix systems. In particular, os.getgroups() does not reflect

4842 information as the id command. os.getgroups() can now return more than 16
4843 groups on MacOSX.

4882 ``datetime.timezone``, return fixed name and UTC offset from their
4883 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

Georg Brandl62069d32010-07-31 08:56:11 +00004912 the result is now always correctly rounded, and is equivalent to ``td /

Antoine Pitrou716c4442009-05-23 19:04:03 +00005413- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitroue4501852009-05-14 18:55:55 +00005435- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5436 library. This means, for example, that opening an UTF-16 text file in
5437 append mode doesn't add a BOM at the end of the file if the file isn't

Mark Dickinson865e01a2009-05-07 16:37:01 +00005491- Issue #5914: Add new C API function PyOS_string_to_double, and
5492 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5493
Eric Smith741191f2009-05-06 13:08:15 +00005494- Issue #3382: float.__format__, complex.__format__, and %-formatting
5495 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

5497
Mark Hammond5a607a32009-05-06 08:04:54 +00005498- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5499 in all operations, including splitdrive, split, etc. splitunc() now issues
5500 a PendingDeprecation warning.
5501
Eric Smith63376222009-05-05 14:04:18 +00005502- Issue #5920: For float.__format__, change the behavior with the
5503 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5504 to be like 'g' but with at least one decimal point and with a
5505 default precision of 12. Previously, the behavior the same but with
5506 a default precision of 6. This more closely matches str(), and
5507 reduces surprises when adding alignment flags to the empty
5508 presentation type. This also affects the new complex.__format__ in
5509 the same way.
5510
Martin v. Löwis011e8422009-05-05 04:43:17 +00005511- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00005513- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5514 shadowed by classtype's, even if it was None. property now
5515 inserts the __doc__ into the subclass instance __dict__.
5516
Antoine Pitrou244651a2009-05-04 18:56:13 +00005517- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005522- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5523 received a new method, detach(). detach() disconnects the underlying stream
5524 from the buffer or text IO and returns it.
5525
Mark Dickinson33841c32009-05-01 15:37:04 +00005526- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5527 floats with absolute value over 1e50. Also remove length
5528 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5529 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00005532 format(complex(1, 2./3), '.5') now produces a sensible result.
5533

5535 never gives more than the requested number of significant digits.
5536
Eric Smith6dc46f52009-04-27 20:39:49 +00005537- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5543 titlecase, but not their own uppercase.
5544

5546
Mark Dickinsonad476da2009-04-23 19:14:16 +00005547- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5548 z involves nans, infs or negative zeros.
5549
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005550- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005551
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005552- Issue #1869 (and many duplicates): make round(x, n) correctly
5553 rounded for a float x, by using the decimal <-> binary conversions
5554 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5555 consistently agrees with format(x, '.2f').
5556
Benjamin Petersonae937c02009-04-18 20:54:08 +00005557- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5563 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005564
5565- Implement PEP 378, Format Specifier for Thousands Separator, for
5566 floats.
5567
Mark Dickinson3370cce2009-04-17 22:40:53 +00005568- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005569 1e11, not 1e12. This avoids printing 13 significant digits in
5570 situations where only 12 of them are correct. Example problem
5571 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5572 long time.)
5573
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005574- Issue #1580: On most platforms, use a 'short' float repr: for a
5575 finite float x, repr(x) now outputs a string based on the shortest
5576 sequence of decimal digits that rounds to x. Previous behaviour was
5577 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005578 Another minor difference is that the new repr switches to
5579 exponential notation at 1e16 instead of the previous 1e17; this
5580 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005581
5582 There's a new sys attribute sys.float_repr_style, which takes
5583 the value 'short' to indicate that we're using short float repr,
5584 and 'legacy' if the short float repr isn't available for one
5585 reason or another.
5586
5587 The float repr change involves incorporating David Gay's 'perfect
5588 rounding' code into the Python core (it's in Python/dtoa.c). As a
5589 secondary consequence, all string-to-float and float-to-string
5590 conversions (including all float formatting operations) will be
5591 correctly rounded on these platforms.
5592
Georg Brandl5f90d792010-08-01 22:31:05 +00005593 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005594 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005596- Issue #5759: float() didn't call __float__ on str subclasses.
5597
Georg Brandlabc38772009-04-12 15:51:51 +00005598- The string.maketrans() function is deprecated; there is a new static method
5599 maketrans() on the bytes and bytearray classes. This removes confusion about
5600 the types string.maketrans() is supposed to work with, and mirrors the
5601 methods available on the str class.
5602
R. David Murraydc6da8a2009-04-09 22:16:43 +00005603- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005866 struct.error instead of returning b'\xff\xff\xff\xff'. The
5867 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5868 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005895- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5896 it now forces its argument to double before testing for infinity.
5897
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005898- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005907
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005908- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005909 were suppressing all exceptions. These include list() and bytearray().

5913
Antoine Pitroub52ec782009-01-25 16:34:23 +00005914- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5915 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5916 evaluation loop is compiled with a new dispatch mechanism which gives
5917 speedups of up to 20%, depending on the system, on various benchmarks.
5918
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005919- Issue #4874: Most builtin decoders now reject unicode input.

5927 optional module state data.
5928
Mark Dickinson8055afd2009-01-17 10:04:45 +00005929- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005930 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005931
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005932- Issue #4935: The overflow checking code in the expandtabs() method common
5933 to str, bytes and bytearray could be optimized away by the compiler, letting
5934 the interpreter segfault instead of raising an error.
5935
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005936- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5937 __next__ method.
5938
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005939- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5940 function no longer attempt to call the __long__ slot to convert an object
5941 to an integer. Only the __int__ and __trunc__ slots are examined.
5942
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005943- Issue #4893: Use NT threading on CE.
5944

5946
Antoine Pitrouab868312009-01-10 15:40:25 +00005947- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5948 common cases are optimized thanks to a dedicated fast path and a moderate
5949 amount of loop unrolling.
5950
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005951- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5952 collecting the oldest generation) so that allocating lots of objects without
5953 destroying them does not show quadratic performance. Based on a proposal by
5954 Martin von Löwis at
5955 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5956
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005957- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005958 having been closed (for instance, a read() call could return some
5959 previously buffered data). Patch by Dmitry Vasiliev.
5960
Antoine Pitrou05608432009-01-09 18:53:14 +00005961- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5962 flag to work properly. Furthermore, when specifying -u, the text stdout
5963 and stderr streams have line-by-line buffering enabled (the default being
5964 to buffer arbitrary chunks of data).
5965
Raymond Hettinger35631532009-01-09 03:58:09 +00005966- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5967 instead of ints (reducing its size from 4 to 8 times thereby reducing
5968 Python's overall memory).
5969
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005970- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5971 an existing .py counterpart, override the co_filename attributes of all
5972 code objects if the original filename is obsolete (which can happen if the
5973 file has been renamed, moved, or if it is accessed through different paths).
5974 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5975
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005976- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5977 one byte. Also fixes the meaning of len() so that it returns the number of
5978 items, rather than the size in bytes.
5979
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005980- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5981
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005982- Issue #4747: When the terminal does not use utf-8, executing a script with
5983 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5984
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005985- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5986 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005987
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005988- Issue #3680: Reference cycles created through a dict, set or deque iterator
5989 did not get collected.
5990
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005991- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5992 where the tp_hash and tp_dict slots are both NULL.
5993
Georg Brandlccc47b62008-12-28 11:44:14 +00005994- Issue #4759: None is now allowed as the first argument of
5995 bytearray.translate(). It was always allowed for bytes.translate().
5996
Skip Montanaro80072cb2008-12-23 03:51:14 +00005997- Added test case to ensure attempts to read from a file opened for writing
5998 fail.
5999
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006000- Issue #3106: Speedup some comparisons (str/str and int/int).

6004
Antoine Pitrou621601a2008-12-17 23:18:19 +00006005- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6006 print elapsed times, not only when some objects are uncollectable /
6007 unreachable. Original patch by Neil Schemenauer.
6008
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006009- Issue #3439: Add a bit_length method to int.
6010
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006011- Issue #2173: When getting device encoding, check that return value of
6012 nl_langinfo is not the empty string. This was causing silent build
6013 failures on OS X.
6014
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006015- Issue #4597: Fixed several opcodes that weren't always propagating
6016 exceptions.
6017
6018- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006019 context manager returns a value that cannot be converted to a bool.
6020
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006021- Issue #4445: Replace "sizeof(PyBytesObject)" with
6022 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6023 bytes instances. On a typical machine this saves 3 bytes of memory
6024 (on average) per allocation of a bytes instance.
6025
Christian Heimesa872de52008-12-05 08:26:55 +00006026- Issue #4533: File read operation was dreadfully slow due to a slowly
6027 growing read buffer. Fixed by using the same growth rate algorithm as
6028 Python 2.x.
6029
Antoine Pitrou5504e892008-12-06 21:27:53 +00006030- Issue #4509: Various issues surrounding resize of bytearray objects to
6031 which there are buffer exports (e.g. memoryview instances).
6032
Georg Brandlf9734072008-12-07 15:30:06 +00006033- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6034 method on file objects with closefd=False. The file descriptor is still
6035 kept open but the file object behaves like a closed file. The ``FileIO``
6036 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006037
Antoine Pitroubc420402008-12-07 20:14:49 +00006038- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6039 larger than 1.

6044
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006045- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6046 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6047 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6048 of using the replace error handler in PyUnicode_DecodeUTF8().
