14

17
Antoine Pitrou6c40eb72012-01-18 20:16:09 +010018- Fix the builtin module initialization code to store the init function for
19 future reinitialization.
20
Gregory P. Smith9564e4c2012-01-21 14:50:11 -080021- Issue #8052: The posix subprocess module would take a long time closing
22 all possible file descriptors in the child process rather than just open
23 file descriptors. It now closes only the open fds if possible for the
24 default close_fds=True behavior.
25
Meador Inge33880602012-01-15 19:15:36 -060026- Issue #13629: Renumber the tokens in token.h so that they match the indexes

30 effect of appearing to resolve the issue. Thanks to Mark Shannon for
31 noticing.
32

Antoine Pitrou11942a52011-11-28 19:08:36 +010039- Issue #7111: Python can now be run without a stdin, stdout or stderr
40 stream. It was already the case with Python 2. However, the corresponding
41 sys module entries are now set to None (instead of an unusable file object).
42
Amaury Forgeot d'Arc58e87612011-11-22 21:51:55 +010043- Issue #13436: Fix a bogus error message when an AST object was passed

57 variable in the default value of a keyword-only argument:
58 (lambda *, arg=GLOBAL_NAME: None)
59

817 still possible to globally override the default by setting

820 was built.

1494 files in binary mode, using the email package's binary support to parse

1554 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1555 of HTTP 1.1.
1556
Armin Ronacher59531282011-01-22 13:44:22 +00001557- To match the behaviour of HTTP server, the HTTP client library now also
1558 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1559 that for incoming headers which makes this behaviour now consistent in
1560 both incoming and outgoing direction.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002315- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2316 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002317 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002318 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002319 encoding and to encode command line arguments on this OS.

Benjamin Peterson230b2062010-10-16 03:45:45 +00002325- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl27a28582010-10-10 09:49:21 +00002711- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2712 with a non-empty format string. This is an effort to future-proof user
2713 code. If a derived class does not currently implement __format__ but later
2714 adds its own __format__, it would most likely break user code that had
2715 supplied a format string. This will be changed to a DeprecationWaring in
2716 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002718- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2719 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2720 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2721
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002722- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2723 functions from the libc caused the methods .upper() and lower() to become
2724 locale aware and created subtly wrong results.
2725
Georg Brandl27a28582010-10-10 09:49:21 +00002726- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2727 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002728
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002729- Issue #4617: Previously it was illegal to delete a name from the local
2730 namespace if it occurs as a free variable in a nested block. This limitation
2731 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2732
Georg Brandl27a28582010-10-10 09:49:21 +00002733- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2734 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2735 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2736 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002737
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002738- Issue #9757: memoryview objects get a release() method to release the
2739 underlying buffer (previously this was only done when deallocating the
2740 memoryview), and gain support for the context management protocol.
2741
Antoine Pitrou079ce542010-09-08 12:37:10 +00002742- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2743 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002759- Issue #4661: email can now parse bytes input and generate either converted
2760 7bit output or bytes output. Email version bumped to 5.1.0.

Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002765- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2766 after the file is closed. Patch by Jeffrey Finkelstein.
2767
Éric Araujo6108bf52010-10-04 23:52:37 +00002768- Issue #9042: Fix interaction of custom translation classes and caching in
2769 gettext.
2770
Éric Araujoef777bd2010-10-05 00:04:20 +00002771- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002772 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002773 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002774 replacement for old handle_accept() and avoids the user to call accept()
2775 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002777- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Georg Brandl27a28582010-10-10 09:49:21 +00002780- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2781 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002782
R. David Murray5397e862010-10-02 15:58:26 +00002783- Issue #1050268: parseaddr now correctly quotes double quote and backslash

Georg Brandl27a28582010-10-10 09:49:21 +00002786- Issue #10004: quoprimime no longer generates a traceback when confronted with

Georg Brandl27a28582010-10-10 09:49:21 +00002792- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2793 conforms to the philosophy of bytes and unicode separation in Python 3. A
2794 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002795
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002796- Issue #9962: GzipFile now has the peek() method.
2797
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002798- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002799 retry the select() loop instead of bailing out. This is because select() can
2800 incorrectly report a socket as ready for reading (for example, if it received
2801 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002802
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002803- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2804
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002805- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002806 received. Now sendall() properly calls signal handlers if necessary, and
2807 retries sending if these returned successfully, including on sockets with a
2808 timeout.

2818
Antoine Pitrou70c60442010-09-23 19:51:39 +00002819- Issue #9928: Properly initialize the types exported by the bz2 module.

Georg Brandl27a28582010-10-10 09:49:21 +00002821- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
2822 Florian Festi.
Antoine Pitrou7b969842010-09-23 16:22:51 +00002823
Vinay Sajip0637d492010-09-23 08:15:54 +00002824- Logging: Added QueueListener class to facilitate logging usage for
2825 performance-critical threads.

2832
Antoine Pitrou38425292010-09-21 18:19:07 +00002833- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
2834
Antoine Pitrou52d42502010-09-21 16:08:27 +00002835- Issue #2643: msync() is not called anymore when deallocating an open mmap
2836 object, only munmap().
2837
Georg Brandl27a28582010-10-10 09:49:21 +00002838- logging: Changed LoggerAdapter implementation internally, to make it easier to
2839 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002840
Vinay Sajipc84f0162010-09-21 11:25:39 +00002841- logging: hasHandlers method was added to Logger, and isEnabledFor,
2842 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
2843 LoggerAdapter was introduced into the unit tests for logging.
2844
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00002845- Issue #1686: Fix string.Template when overriding the pattern attribute.
2846
Antoine Pitrou98b46702010-09-18 22:59:00 +00002847- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002848 non-blocking mode: they return None when an operation would block (instead of
2849 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002850
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002851- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
2852 another kind.
2853
Vinay Sajip19ec67a2010-09-17 18:57:36 +00002854- Issue #9441: logging has better coverage for rotating file handlers.
2855
Georg Brandl27a28582010-10-10 09:49:21 +00002856- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
Raymond Hettinger35c87f22010-09-16 19:10:17 +00002857
Georg Brandl27a28582010-10-10 09:49:21 +00002858- Issue #9854: The default read() implementation in io.RawIOBase now handles
2859 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002860
Georg Brandl27a28582010-10-10 09:49:21 +00002861- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2862 supporting the whole socket API (rather than the "raw" _socket.socket
2863 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002864
Georg Brandl27a28582010-10-10 09:49:21 +00002865- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2866 to match the corresponding socket methods.
Antoine Pitroua468adc2010-09-14 14:43:44 +00002867
Éric Araujod8c73c62011-03-21 03:15:22 +01002868- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002869 them handle recursive calls within the same thread.
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +00002870
Vinay Sajipaf9d10a2010-09-13 20:40:30 +00002871- logging: Enhanced HTTPHandler with secure and credentials initializers.

Victor Stinnerccb706c2010-09-13 19:41:36 +00002874
Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002875- Issue #9837: The read() method of ZipExtFile objects (as returned by
2876 ZipFile.open()) could return more bytes than requested.
2877
Georg Brandl27a28582010-10-10 09:49:21 +00002878- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2879 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002880
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002881- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002882 it possible for the user to create self-referencing ordered dictionaries which
2883 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002884 approach of using weakref proxies so that reference cycles never get created
2885 in the first place.
2886
Victor Stinnercb043522010-09-10 23:49:04 +00002887- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2888 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002889 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002890
Georg Brandl27a28582010-10-10 09:49:21 +00002891- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2892 environment variable to set the filesystem encoding at Python startup.
2893 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2894 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002895
Georg Brandl27a28582010-10-10 09:49:21 +00002896- Issue #9410: Various optimizations to the pickle module, leading to speedups
2897 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2898 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002899
Georg Brandl27a28582010-10-10 09:49:21 +00002900- The pprint module now supports printing OrderedDicts in their given order
2901 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002902
Vinay Sajip121a1c42010-09-08 10:46:15 +00002903- Logging: Added QueueHandler class to facilitate logging usage with
2904 multiprocessing.
2905
Georg Brandl27a28582010-10-10 09:49:21 +00002906- Issue #9707: Rewritten reference implementation of threading.local which is
2907 friendlier towards reference cycles. This change is not normally visible
2908 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002909
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002910- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2911 still return the id of the parent process after it has exited. This process
2912 id may even have been reused by another unrelated process.
2913
Georg Brandl27a28582010-10-10 09:49:21 +00002914- Issue #9792: In case of connection failure, socket.create_connection() would
2915 swallow the exception and raise a new one, making it impossible to fetch the
2916 original errno, or to filter timeout errors. Now the original error is
2917 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002918
Georg Brandl27a28582010-10-10 09:49:21 +00002919- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2920 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2921 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002922
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002923- Updates to the random module:
2924
Georg Brandl27a28582010-10-10 09:49:21 +00002925 * Document which parts of the module are guaranteed to stay the same across
2926 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002927
Georg Brandl27a28582010-10-10 09:49:21 +00002928 * Update the seed() method to use all of the bits in a string instead of just
2929 the hash value. This makes better use of the seed value and assures the
2930 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002931
Georg Brandl27a28582010-10-10 09:49:21 +00002932 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2933 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2934 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002935
2936 * Improved documentation of arguments to randrange(). Issue #9379.
Raymond Hettingerf763a722010-09-07 00:38:15 +00002937
Georg Brandl27a28582010-10-10 09:49:21 +00002938- collections.OrderedDict now supports a new method for repositioning keys to
2939 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00002940
Georg Brandl27a28582010-10-10 09:49:21 +00002941- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2942 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2943 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002944
Georg Brandl27a28582010-10-10 09:49:21 +00002945- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2946 their contents without duplicating them. The view is both readable and
2947 writable.
Antoine Pitrou972ee132010-09-06 18:48:21 +00002948
Brian Curtin62857742010-09-06 17:07:27 +00002949- Issue #7566: Implement os.path.sameopenfile for Windows.
2950
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002951- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002952 unsupported operation is attempted (for example, writing to a file open only

3087 return characters from the full Unicode range, even on narrow unicode builds
3088 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

3090 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00003127- Issue #9416: Fix some issues with complex formatting where the output with no
3128 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003129
3130 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3131 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +00003463- Issue #8991: convertbuffer() rejects discontigious buffers.
3464
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003465- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

3469
Ezio Melotti57221d02010-07-01 07:32:02 +00003470- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003471 start byte and the continuation byte(s) are now considered invalid, instead of
3472 the number of bytes specified by the start byte. E.g.:
3473 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3474 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3475 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3476 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003478- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3479 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00003490- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3491 dealing with unary minus applied to a constant. The removed code was mutating
3492 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003493
Victor Stinner554f3f02010-06-16 23:33:54 +00003494- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003495 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003496 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003497 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003498
Victor Stinner25e8ec42010-06-25 00:02:38 +00003499- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3500 "w*" format instead. Add tests for "w*" format.
3501
Victor Stinner06e49dd2010-06-13 18:21:50 +00003502- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003503 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003504 string formats.
3505
Georg Brandl62069d32010-07-31 08:56:11 +00003506- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003507 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3508 location of the raised exception.
3509
Victor Stinner313a1202010-06-11 23:56:51 +00003510- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3511 filenames and enable os.fsencode().
3512
Benjamin Peterson285a6892010-06-22 19:21:52 +00003513- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3514
Georg Brandl62069d32010-07-31 08:56:11 +00003515- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3516 interpreter with characters outside the Basic Multilingual Plane (higher than
3517 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003518
Georg Brandl62069d32010-07-31 08:56:11 +00003519- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3520 TypeError instead of giving a DeprecationWarning when a float is parsed using
3521 the 'L' code (for long long). (All other integer codes already raise
3522 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003523
Victor Stinner600d3be2010-06-10 12:00:55 +00003524- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3525 enable shortcuts for upper case encoding name. Add also a shortcut for
3526 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3527
Georg Brandl62069d32010-07-31 08:56:11 +00003528- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3529 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003530
3531- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003532 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003533 like bytearray.
3534
Georg Brandl62069d32010-07-31 08:56:11 +00003535- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003536 used anymore and it was never documented.
3537
Georg Brandl62069d32010-07-31 08:56:11 +00003538- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003539
Georg Brandl62069d32010-07-31 08:56:11 +00003540- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3541 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003542
Georg Brandl62069d32010-07-31 08:56:11 +00003543- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3544 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3545 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3546 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003547
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003548- Issue #8748: Fix two issues with comparisons between complex and integer
3549 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003550 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3551 (2) The comparison raised an OverflowError for large integers, leading to
3552 unpredictable exceptions when combining integers and complex objects in sets
3553 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003554
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003555- Issue #8766: Initialize _warnings module before importing the first module.
3556 Fix a crash if an empty directory called "encodings" exists in sys.path.
3557
Victor Stinner9ca9c252010-05-19 16:53:30 +00003558- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003559 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003560 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003561
Georg Brandl62069d32010-07-31 08:56:11 +00003562- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3563 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003564
Victor Stinnerae6265f2010-05-15 16:27:27 +00003565- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3566 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003567 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003568 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003569
Victor Stinner59e62db2010-05-15 13:14:32 +00003570- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003571 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003572
Victor Stinnerb744ba12010-05-15 12:27:16 +00003573- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003574 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003575 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3576
Victor Stinner0964ee12010-04-30 16:48:45 +00003577- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003578 PyUnicode_FromString() to support surrogates in the filename and use the right
3579 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003580
Georg Brandl8569e582010-05-19 20:57:08 +00003581- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3582
Georg Brandl62069d32010-07-31 08:56:11 +00003583- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003584
Benjamin Petersonfb886362010-04-24 18:21:17 +00003585- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3586 arguments.
3587
Victor Stinner14284c22010-04-23 12:02:30 +00003588- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003589 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Victor Stinnerdcb24032010-04-22 12:08:36 +00003597
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003598- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003599 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003682- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003683 where the right hand operand is a set of constants, by turning the set into a
3684 frozenset and pre-building it as a constant. The comparison operation is made
3685 against the constant instead of building a new set each time it is executed (a
3686 similar optimization already existed which turned a list of constants into a
3687 pre-built tuple). Patch and additional tests by Dave Malcolm.

Georg Brandl62069d32010-07-31 08:56:11 +00003988- The default size of the re module's compiled regular expression cache has been
3989 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003990 simply clearing the entire cache on overflow to forgetting the least recently
3991 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003992 applications that use a lot of regular expressions and limits the impact of
3993 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004005- Issue #7989: Added pure python implementation of the `datetime` module. The C
4006 module is renamed to `_datetime` and if available, overrides all classes
4007 defined in datetime with fast C impementation. Python implementation is based
4008 on the original python prototype for the datetime module by Tim Peters with
4009 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004365- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004366 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004367 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00004373- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004374 filename and date, conforming to the 'standards' they were originally designed

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004391- Add functools.total_ordering() and functools.cmp_to_key().
4392
Georg Brandl62069d32010-07-31 08:56:11 +00004393- Issue #8257: The Decimal construct now accepts a float instance directly,
4394 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004395
4396 >>> Decimal(1.1)
4397 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004402- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4403 InvalidOperation instead of returning False. (Comparisons involving a quiet
4404 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4405 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004406
Georg Brandl62069d32010-07-31 08:56:11 +00004407- Issue #2531: Comparison operations between floats and Decimal instances now
4408 return a result based on the numeric values of the operands; previously they
4409 returned an arbitrary result based on the relative ordering of id(float) and
4410 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4411 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004412
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004413- Added a subtract() method to collections.Counter().
4414
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004415- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004416 argument `-` which tells it to read files to compile from stdin. Each line is
4417 read on demand and the named file is compiled immediately. (Original patch by
4418 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004420- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004424- Comparisons using one of <, <=, >, >= between a complex instance and a
4425 Fractions instance now raise TypeError instead of returning True/False. This
4426 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4427 <=> complex, and complex <=> complex comparisons.

4435
Antoine Pitrou910bd512010-03-22 20:11:09 +00004436- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004437 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004470- The internals of the subprocess module on POSIX systems have been replaced by
4471 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4472 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004473
Georg Brandl62069d32010-07-31 08:56:11 +00004474- subprocess.Popen now has restore_signals and start_new_session features. The
4475 default of restore_signals=True is a new behavior compared to earlier Python
4476 versions. This means that signals such as SIGPIPE are not ignored by default
4477 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004563- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4564 position when calling `truncate()`. It would previously change the file
4565 position to the given argument, which goes against the tradition of

4570 archive. The new implementation is significantly faster and can be wrapped in
4571 a :class:`io.BufferedReader` object for more speedups. It also solves an
4572 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004970- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004971 compared to other unix systems. In particular, os.getgroups() does not reflect

4974 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00005566- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5567 library. This means, for example, that opening an UTF-16 text file in
5568 append mode doesn't add a BOM at the end of the file if the file isn't
5569 empty.

5619Core and Builtins
5620-----------------
5621
Mark Dickinson865e01a2009-05-07 16:37:01 +00005622- Issue #5914: Add new C API function PyOS_string_to_double, and
5623 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5624
Eric Smith741191f2009-05-06 13:08:15 +00005625- Issue #3382: float.__format__, complex.__format__, and %-formatting
5626 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5627 affects nan -> NAN and inf -> INF.
5628
Mark Hammond5a607a32009-05-06 08:04:54 +00005629- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5630 in all operations, including splitdrive, split, etc. splitunc() now issues
5631 a PendingDeprecation warning.
5632
Eric Smith63376222009-05-05 14:04:18 +00005633- Issue #5920: For float.__format__, change the behavior with the
5634 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5635 to be like 'g' but with at least one decimal point and with a
5636 default precision of 12. Previously, the behavior the same but with
5637 a default precision of 6. This more closely matches str(), and
5638 reduces surprises when adding alignment flags to the empty
5639 presentation type. This also affects the new complex.__format__ in
5640 the same way.
5641
Martin v. Löwis011e8422009-05-05 04:43:17 +00005642- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5643
R. David Murrayb18500d2009-05-04 22:59:07 +00005644- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5645 shadowed by classtype's, even if it was None. property now
5646 inserts the __doc__ into the subclass instance __dict__.
5647
Antoine Pitrou244651a2009-05-04 18:56:13 +00005648- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5649 sequences. Patch by Nick Barnes and Victor Stinner.
5650
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005651- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005652
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005653- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5654 received a new method, detach(). detach() disconnects the underlying stream
5655 from the buffer or text IO and returns it.
5656
Mark Dickinson33841c32009-05-01 15:37:04 +00005657- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5658 floats with absolute value over 1e50. Also remove length
5659 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5660 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005661
Eric Smith741191f2009-05-06 13:08:15 +00005662- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005663 format(complex(1, 2./3), '.5') now produces a sensible result.
5664
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005665- Issue #5864: Fix empty format code formatting for floats so that it
5666 never gives more than the requested number of significant digits.
5667
Eric Smith6dc46f52009-04-27 20:39:49 +00005668- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5669 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5670
Eric Smithcc32a112009-04-26 21:35:14 +00005671- Issue #5835: Deprecate PyOS_ascii_formatd.
5672
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005673- Issue #4971: Fix titlecase for characters that are their own
5674 titlecase, but not their own uppercase.
5675
Benjamin Peterson193152c2009-04-25 01:08:45 +00005676- Issue #5283: Setting __class__ in __del__ caused a segfault.
5677
Mark Dickinsonad476da2009-04-23 19:14:16 +00005678- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5679 z involves nans, infs or negative zeros.
5680
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005681- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005682
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005683- Issue #1869 (and many duplicates): make round(x, n) correctly
5684 rounded for a float x, by using the decimal <-> binary conversions
5685 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5686 consistently agrees with format(x, '.2f').
5687
Benjamin Petersonae937c02009-04-18 20:54:08 +00005688- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5689 some builtin types.
5690
Eric Smith0923d1d2009-04-16 20:16:10 +00005691- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5692
Eric Smith35e84722009-04-16 20:21:28 +00005693- Issue #5515: str.format() type 'n' combined with commas and leading
5694 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005695
5696- Implement PEP 378, Format Specifier for Thousands Separator, for
5697 floats.
5698
Mark Dickinson3370cce2009-04-17 22:40:53 +00005699- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005700 1e11, not 1e12. This avoids printing 13 significant digits in
5701 situations where only 12 of them are correct. Example problem
5702 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5703 long time.)
5704
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005705- Issue #1580: On most platforms, use a 'short' float repr: for a
5706 finite float x, repr(x) now outputs a string based on the shortest
5707 sequence of decimal digits that rounds to x. Previous behaviour was
5708 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005709 Another minor difference is that the new repr switches to
5710 exponential notation at 1e16 instead of the previous 1e17; this
5711 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005712
5713 There's a new sys attribute sys.float_repr_style, which takes
5714 the value 'short' to indicate that we're using short float repr,
5715 and 'legacy' if the short float repr isn't available for one
5716 reason or another.
5717
5718 The float repr change involves incorporating David Gay's 'perfect
5719 rounding' code into the Python core (it's in Python/dtoa.c). As a
5720 secondary consequence, all string-to-float and float-to-string
5721 conversions (including all float formatting operations) will be
5722 correctly rounded on these platforms.
5723
Georg Brandl5f90d792010-08-01 22:31:05 +00005724 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005725 this change does not apply.
5726
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005727- Issue #5759: float() didn't call __float__ on str subclasses.
5728
Georg Brandlabc38772009-04-12 15:51:51 +00005729- The string.maketrans() function is deprecated; there is a new static method
5730 maketrans() on the bytes and bytearray classes. This removes confusion about
5731 the types string.maketrans() is supposed to work with, and mirrors the
5732 methods available on the str class.
5733
R. David Murraydc6da8a2009-04-09 22:16:43 +00005734- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5735 its clarity and its speed.
5736
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005737- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005738 to avoid compiler warnings.
5739
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005740- Issue #3739: The unicode-internal encoder now reports the number of characters
5741 consumed like any other encoder (instead of the number of bytes).

5889 insufficient checks in accessors of Exception.__context__.
5890
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005891- Issue #5604: non-ASCII characters in module name passed to
5892 imp.find_module() were converted to UTF-8 while the path is
5893 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00005895- Issue #5126: str.isprintable() returned False for space characters.
5896
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005897- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5898 the end sys.path, for compatibility with the system install of Python.
5899
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005900- Issue #4688: Add a heuristic so that tuples and dicts containing only
5901 untrackable objects are not tracked by the garbage collector. This can
5902 reduce the size of collections and therefore the garbage collection overhead
5903 on long-running programs, depending on their particular use of datatypes.
5904
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005905- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5917 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5918 and sizeof(Py_UNICODE) == 2.
5919
Eric Smith8ec90442009-03-14 12:29:34 +00005920- Issue #5237: Allow auto-numbered fields in str.format(). For

5922
Antoine Pitrou652e7072009-03-13 19:25:20 +00005923- Issue #5392: when a very low recursion limit was set, the interpreter would
5924 abort with a fatal error after the recursion limit was hit twice.
5925
Matthias Klose042f1332009-04-04 14:32:42 +00005926- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

5972
Lars Gustäbel42e00912009-03-22 20:34:29 +00005973- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5974 forever on incomplete input. That caused tarfile.open() to hang when used
5975 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5976 partial bzip2 compressed data.
5977
Mark Dickinson79f52032009-03-17 23:12:51 +00005978- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00006026- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6027 it now forces its argument to double before testing for infinity.
6028
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006029- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6030 returns a non-number type.
6031
Benjamin Peterson87618552009-02-08 15:00:52 +00006032- Issue #5182: Removed memoryview.__str__.

Raymond Hettingere8364232009-02-02 22:55:09 +00006040 were suppressing all exceptions. These include list() and bytearray().
6041
Mark Dickinson1124e712009-01-28 21:25:58 +00006042- Issue #4707: round(x, n) now returns an integer if x is an integer.
6043 Previously it returned a float.

6046 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6047 evaluation loop is compiled with a new dispatch mechanism which gives
6048 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006063- Issue #4935: The overflow checking code in the expandtabs() method common
6064 to str, bytes and bytearray could be optimized away by the compiler, letting
6065 the interpreter segfault instead of raising an error.
6066
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006067- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006089 having been closed (for instance, a read() call could return some
6090 previously buffered data). Patch by Dmitry Vasiliev.
6091
Antoine Pitrou05608432009-01-09 18:53:14 +00006092- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6093 flag to work properly. Furthermore, when specifying -u, the text stdout
6094 and stderr streams have line-by-line buffering enabled (the default being
6095 to buffer arbitrary chunks of data).
6096
Raymond Hettinger35631532009-01-09 03:58:09 +00006097- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6098 instead of ints (reducing its size from 4 to 8 times thereby reducing
6099 Python's overall memory).
6100
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006101- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6102 an existing .py counterpart, override the co_filename attributes of all
6103 code objects if the original filename is obsolete (which can happen if the
6104 file has been renamed, moved, or if it is accessed through different paths).
6105 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6106
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006107- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6108 one byte. Also fixes the meaning of len() so that it returns the number of
6109 items, rather than the size in bytes.
6110
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006111- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6112
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006113- Issue #4747: When the terminal does not use utf-8, executing a script with

6123 where the tp_hash and tp_dict slots are both NULL.
6124
Georg Brandlccc47b62008-12-28 11:44:14 +00006125- Issue #4759: None is now allowed as the first argument of
6126 bytearray.translate(). It was always allowed for bytes.translate().
6127

6498
Antoine Pitrou08838b62009-01-21 00:55:13 +00006499- Issue #5008: When a file is opened in append mode with the new IO library,
6500 do an explicit seek to the end of file (so that e.g. tell() returns the

6532 appropriately when it is being used via socket.makefile() objects
6533 rather than delaying the close by waiting for garbage collection to do it.
6534
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006535- Issue #1696199: Add collections.Counter() for rapid and convenient
