Ned Deily657b2de2011-06-28 19:51:30 -0700711- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
712 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
713 interpreter process. This could cause failures in non-Distutils subprocesses
714 and was unreliable since tests or user programs could modify the interpreter
715 environment after Distutils set it. Instead, have Distutils set the the
716 deployment target only in the environment of each build subprocess. It is
717 still possible to globally override the default by setting
718 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
719 greater or equal to the default value, the value with which the interpreter

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001953- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001954 continuation line in the formatted value has no leading white space and looks
1955 like a header. Since Generator uses Header to format all headers, this check
1956 is made for all headers in any serialized message at serialization time. This
1957 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002612 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002613 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2617 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002960- Issue #10068: Global objects which have reference cycles with their module's
2961 dict are now cleared again. This causes issue #7140 to appear again.
2962
Victor Stinner257d38f2010-10-09 10:12:11 +00002963- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002964 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002965
Georg Brandl27a28582010-10-10 09:49:21 +00002966- ast.literal_eval() can now handle negative numbers. It is also a little more
2967 liberal in what it accepts without compromising the safety of the evaluation.
2968 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002969
Benjamin Peterson970d1882010-10-02 17:55:47 +00002970- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2971 result metaclasses can now be ABCs (see #9533).
2972
Victor Stinneraef57e32010-10-02 11:50:49 +00002973- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2974
Victor Stinner5593d8a2010-10-02 11:11:27 +00002975- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002976 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2977 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002978
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002979- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002980 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002981
Victor Stinner137c34c2010-09-29 10:25:54 +00002982- Issue #9979: Create function PyUnicode_AsWideCharString().
2983
Brett Cannon5305a992010-09-27 21:08:38 +00002984- Issue #7397: Mention that importlib.import_module() is probably what someone
2985 really wants to be using in __import__'s docstring.
2986
Georg Brandl27a28582010-10-10 09:49:21 +00002987- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2988 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002989
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002990- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002991 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002992
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002993- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2994
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002995- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2996 threads are still running. Instead, reinitialize the GIL on a second call to
2997 Py_Initialize().
2998
Georg Brandl27a28582010-10-10 09:49:21 +00002999- All SyntaxErrors now have a column offset and therefore a caret when the error
3000 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003001
Brett Cannonbc2eff32010-09-19 21:39:02 +00003002- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3003 module that was imported, but instead gets the module from sys.modules.
3004
Nick Coghlan37ee8502010-12-03 14:26:13 +00003005- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003006 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00003007
Georg Brandl27a28582010-10-10 09:49:21 +00003008- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3009 with a non-empty format string. This is an effort to future-proof user
3010 code. If a derived class does not currently implement __format__ but later
3011 adds its own __format__, it would most likely break user code that had
3012 supplied a format string. This will be changed to a DeprecationWaring in
3013 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003014
Antoine Pitrou1df15362010-09-13 14:16:46 +00003015- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3016 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3017 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3018
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003019- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3020 functions from the libc caused the methods .upper() and lower() to become
3021 locale aware and created subtly wrong results.
3022
Georg Brandl27a28582010-10-10 09:49:21 +00003023- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3024 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003025
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003026- Issue #4617: Previously it was illegal to delete a name from the local
3027 namespace if it occurs as a free variable in a nested block. This limitation
3028 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3029
Georg Brandl27a28582010-10-10 09:49:21 +00003030- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3031 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3032 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3033 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003034
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003035- Issue #9757: memoryview objects get a release() method to release the
3036 underlying buffer (previously this was only done when deallocating the
3037 memoryview), and gain support for the context management protocol.
3038
Antoine Pitrou079ce542010-09-08 12:37:10 +00003039- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3040 thread-local storage key.

3052 not in build_clib.
3053
Antoine Pitroudbec7802010-10-10 09:37:12 +00003054- Issue #9437: Fix building C extensions with non-default LDFLAGS.
3055
R. David Murray96fd54e2010-10-08 15:55:28 +00003056- Issue #4661: email can now parse bytes input and generate either converted
3057 7bit output or bytes output. Email version bumped to 5.1.0.
3058
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003059- Issue #1589: Add ssl.match_hostname(), to help implement server identity
3060 verification for higher-level protocols.
3061
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00003062- Issue #9759: GzipFile now raises ValueError when an operation is attempted
3063 after the file is closed. Patch by Jeffrey Finkelstein.
3064
Éric Araujo6108bf52010-10-04 23:52:37 +00003065- Issue #9042: Fix interaction of custom translation classes and caching in
3066 gettext.
3067
Éric Araujoef777bd2010-10-05 00:04:20 +00003068- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003069 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003070 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003071 replacement for old handle_accept() and avoids the user to call accept()
3072 directly.
3073
Lars Gustäbel331b8002010-10-04 15:18:47 +00003074- Issue #9065: tarfile no longer uses "root" as the default for the uname and

3078 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00003079
R. David Murray5397e862010-10-02 15:58:26 +00003080- Issue #1050268: parseaddr now correctly quotes double quote and backslash
3081 characters that appear inside quoted strings in email addresses.
3082
Georg Brandl27a28582010-10-10 09:49:21 +00003083- Issue #10004: quoprimime no longer generates a traceback when confronted with
3084 invalid characters after '=' in a Q-encoded word.

Georg Brandl27a28582010-10-10 09:49:21 +00003089- Issue #9360: Cleanup and improvements to the nntplib module. The API now
3090 conforms to the philosophy of bytes and unicode separation in Python 3. A
3091 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00003092
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00003093- Issue #9962: GzipFile now has the peek() method.
3094
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003095- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003096 retry the select() loop instead of bailing out. This is because select() can
3097 incorrectly report a socket as ready for reading (for example, if it received
3098 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003099
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00003100- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00003102- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00003103 received. Now sendall() properly calls signal handlers if necessary, and
3104 retries sending if these returned successfully, including on sockets with a
3105 timeout.

Antoine Pitrou52d42502010-09-21 16:08:27 +00003132- Issue #2643: msync() is not called anymore when deallocating an open mmap
3133 object, only munmap().
3134
Georg Brandl27a28582010-10-10 09:49:21 +00003135- logging: Changed LoggerAdapter implementation internally, to make it easier to
3136 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00003137
Vinay Sajipc84f0162010-09-21 11:25:39 +00003138- logging: hasHandlers method was added to Logger, and isEnabledFor,

Antoine Pitrou98b46702010-09-18 22:59:00 +00003144- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003145 non-blocking mode: they return None when an operation would block (instead of

Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00003148- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00003155- Issue #9854: The default read() implementation in io.RawIOBase now handles
3156 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00003157
Georg Brandl27a28582010-10-10 09:49:21 +00003158- Issue #1552: socket.socketpair() now returns regular socket.socket objects
3159 supporting the whole socket API (rather than the "raw" _socket.socket
3160 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00003161

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003178- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003179 it possible for the user to create self-referencing ordered dictionaries which
3180 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003181 approach of using weakref proxies so that reference cycles never get created
3182 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003188- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3189 environment variable to set the filesystem encoding at Python startup.
3190 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Georg Brandl27a28582010-10-10 09:49:21 +00003197- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00003200- Logging: Added QueueHandler class to facilitate logging usage with
3201 multiprocessing.
3202
Georg Brandl27a28582010-10-10 09:49:21 +00003203- Issue #9707: Rewritten reference implementation of threading.local which is
3204 friendlier towards reference cycles. This change is not normally visible
3205 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003206
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003207- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3208 still return the id of the parent process after it has exited. This process
3209 id may even have been reused by another unrelated process.
3210
Georg Brandl27a28582010-10-10 09:49:21 +00003211- Issue #9792: In case of connection failure, socket.create_connection() would
3212 swallow the exception and raise a new one, making it impossible to fetch the
3213 original errno, or to filter timeout errors. Now the original error is
3214 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003216- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3217 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3218 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003220- Updates to the random module:
3221
Georg Brandl27a28582010-10-10 09:49:21 +00003222 * Document which parts of the module are guaranteed to stay the same across
3223 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003224
Georg Brandl27a28582010-10-10 09:49:21 +00003225 * Update the seed() method to use all of the bits in a string instead of just
3226 the hash value. This makes better use of the seed value and assures the
3227 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003228
Georg Brandl27a28582010-10-10 09:49:21 +00003229 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3230 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3231 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003232
3233 * Improved documentation of arguments to randrange(). Issue #9379.

3239 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3240 given warning type was triggered by the code under test.

3244 writable.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00003248- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003249 unsupported operation is attempted (for example, writing to a file open only

Gregory P. Smith13b55292010-09-06 08:30:23 +00003252- hashlib has two new constant attributes: algorithms_guaranteed and
3253 algorithms_avaiable that respectively list the names of hash algorithms
3254 guaranteed to exist in all Python implementations and the names of hash
3255 algorithms available in the current process.
3256
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003257- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00003360- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3361 now removed, since their effect was inexistent in 3.x (the default encoding is

3384 return characters from the full Unicode range, even on narrow unicode builds
3385 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3386 in Python is that unicodedata.numeric() now returns the correct value for
3387 large code points, and repr() may consider more characters as printable.
3388
Victor Stinner6c00c142010-08-17 23:37:11 +00003389- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

3422 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003423
Georg Brandl649971e2010-09-05 17:06:50 +00003424- Issue #9416: Fix some issues with complex formatting where the output with no
3425 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003426
3427 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3428 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00003767- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003768 start byte and the continuation byte(s) are now considered invalid, instead of
3769 the number of bytes specified by the start byte. E.g.:
3770 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3771 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3772 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3773 returned a single u'\ufffd'.

3788 dealing with unary minus applied to a constant. The removed code was mutating
3789 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003793 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003794 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003795
Victor Stinner25e8ec42010-06-25 00:02:38 +00003796- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3797 "w*" format instead. Add tests for "w*" format.
3798
Victor Stinner06e49dd2010-06-13 18:21:50 +00003799- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003800 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003801 string formats.
3802
Georg Brandl62069d32010-07-31 08:56:11 +00003803- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003804 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3805 location of the raised exception.
3806
Victor Stinner313a1202010-06-11 23:56:51 +00003807- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3808 filenames and enable os.fsencode().
3809
Benjamin Peterson285a6892010-06-22 19:21:52 +00003810- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3811
Georg Brandl62069d32010-07-31 08:56:11 +00003812- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3813 interpreter with characters outside the Basic Multilingual Plane (higher than
3814 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003815
Georg Brandl62069d32010-07-31 08:56:11 +00003816- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3817 TypeError instead of giving a DeprecationWarning when a float is parsed using
3818 the 'L' code (for long long). (All other integer codes already raise
3819 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003820
Victor Stinner600d3be2010-06-10 12:00:55 +00003821- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3822 enable shortcuts for upper case encoding name. Add also a shortcut for
3823 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3824
Georg Brandl62069d32010-07-31 08:56:11 +00003825- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3826 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003827
3828- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003829 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003830 like bytearray.
3831
Georg Brandl62069d32010-07-31 08:56:11 +00003832- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003833 used anymore and it was never documented.
3834
Georg Brandl62069d32010-07-31 08:56:11 +00003835- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003837- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3838 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003839
Georg Brandl62069d32010-07-31 08:56:11 +00003840- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3841 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3842 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3843 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003844
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003845- Issue #8748: Fix two issues with comparisons between complex and integer
3846 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003847 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3848 (2) The comparison raised an OverflowError for large integers, leading to
3849 unpredictable exceptions when combining integers and complex objects in sets
3850 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003851
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003852- Issue #8766: Initialize _warnings module before importing the first module.
3853 Fix a crash if an empty directory called "encodings" exists in sys.path.
3854
Victor Stinner9ca9c252010-05-19 16:53:30 +00003855- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003856 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003857 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003858
Georg Brandl62069d32010-07-31 08:56:11 +00003859- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3860 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003861
Victor Stinnerae6265f2010-05-15 16:27:27 +00003862- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3863 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003864 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003865 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003866
Victor Stinner59e62db2010-05-15 13:14:32 +00003867- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003868 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003869
Victor Stinnerb744ba12010-05-15 12:27:16 +00003870- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003871 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003872 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3873
Victor Stinner0964ee12010-04-30 16:48:45 +00003874- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003875 PyUnicode_FromString() to support surrogates in the filename and use the right
3876 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003878- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3879
Georg Brandl62069d32010-07-31 08:56:11 +00003880- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003881
Benjamin Petersonfb886362010-04-24 18:21:17 +00003882- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3883 arguments.
3884
Victor Stinner14284c22010-04-23 12:02:30 +00003885- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003886 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00003980 where the right hand operand is a set of constants, by turning the set into a

4154 `va_copy`, but available on all python platforms.
4155
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004156- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4157 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

4180 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4181 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004182 to match the behaviour of the other integer format codes.

4193 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4194 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00004289 applications that use a lot of regular expressions and limits the impact of
4290 the performance hit anytime the cache is exceeded.

4705 return a result based on the numeric values of the operands; previously they
4706 returned an arbitrary result based on the relative ordering of id(float) and
4707 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4708 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004712- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004713 argument `-` which tells it to read files to compile from stdin. Each line is

4723 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4724 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004771- subprocess.Popen now has restore_signals and start_new_session features. The
4772 default of restore_signals=True is a new behavior compared to earlier Python
4773 versions. This means that signals such as SIGPIPE are not ignored by default
4774 in subprocesses launched by Python (Issue #1652).

4868 a :class:`io.BufferedReader` object for more speedups. It also solves an
4869 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00005301- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5302 directive. When the ``%z`` directive is present in the format string, an
5303 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5304 ``datetime.timezone`` instance constructed from the parsed offset. If both
5305 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5306 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005309 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5310 ``datetime.timezone``, return fixed name and UTC offset from their
5311 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5312 returns ``None``. A class attribute, ``utc`` contains an instance
5313 representing the UTC timezone. Original patch by Rafe Kaplan.

5810 (1) inf and nan strings with trailing whitespace were incorrectly
5811 rejected; (2) parsing of strings representing infinities and nans
5812 was locale aware; and (3) the interpretation of fromhex('-nan')
5813 didn't match that of float('-nan').

5916Core and Builtins
5917-----------------
5918
Mark Dickinson865e01a2009-05-07 16:37:01 +00005919- Issue #5914: Add new C API function PyOS_string_to_double, and
5920 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5921
Eric Smith741191f2009-05-06 13:08:15 +00005922- Issue #3382: float.__format__, complex.__format__, and %-formatting
5923 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5924 affects nan -> NAN and inf -> INF.
5925
Mark Hammond5a607a32009-05-06 08:04:54 +00005926- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5927 in all operations, including splitdrive, split, etc. splitunc() now issues
5928 a PendingDeprecation warning.
5929
Eric Smith63376222009-05-05 14:04:18 +00005930- Issue #5920: For float.__format__, change the behavior with the
5931 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5932 to be like 'g' but with at least one decimal point and with a
5933 default precision of 12. Previously, the behavior the same but with
5934 a default precision of 6. This more closely matches str(), and
5935 reduces surprises when adding alignment flags to the empty
5936 presentation type. This also affects the new complex.__format__ in
5937 the same way.
5938
Martin v. Löwis011e8422009-05-05 04:43:17 +00005939- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5940
R. David Murrayb18500d2009-05-04 22:59:07 +00005941- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5942 shadowed by classtype's, even if it was None. property now
5943 inserts the __doc__ into the subclass instance __dict__.
5944
Antoine Pitrou244651a2009-05-04 18:56:13 +00005945- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5946 sequences. Patch by Nick Barnes and Victor Stinner.
5947
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005948- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005949
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005950- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5951 received a new method, detach(). detach() disconnects the underlying stream
5952 from the buffer or text IO and returns it.
5953
Mark Dickinson33841c32009-05-01 15:37:04 +00005954- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5955 floats with absolute value over 1e50. Also remove length
5956 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5957 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005958
Eric Smith741191f2009-05-06 13:08:15 +00005959- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005960 format(complex(1, 2./3), '.5') now produces a sensible result.
5961
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005962- Issue #5864: Fix empty format code formatting for floats so that it
5963 never gives more than the requested number of significant digits.
5964
Eric Smith6dc46f52009-04-27 20:39:49 +00005965- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5966 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5967
Eric Smithcc32a112009-04-26 21:35:14 +00005968- Issue #5835: Deprecate PyOS_ascii_formatd.
5969
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005970- Issue #4971: Fix titlecase for characters that are their own
5971 titlecase, but not their own uppercase.
5972
Benjamin Peterson193152c2009-04-25 01:08:45 +00005973- Issue #5283: Setting __class__ in __del__ caused a segfault.
5974
Mark Dickinsonad476da2009-04-23 19:14:16 +00005975- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5976 z involves nans, infs or negative zeros.
5977
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005978- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005979
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005980- Issue #1869 (and many duplicates): make round(x, n) correctly
5981 rounded for a float x, by using the decimal <-> binary conversions
5982 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5983 consistently agrees with format(x, '.2f').
5984
Benjamin Petersonae937c02009-04-18 20:54:08 +00005985- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5986 some builtin types.
5987
Eric Smith0923d1d2009-04-16 20:16:10 +00005988- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5989
Eric Smith35e84722009-04-16 20:21:28 +00005990- Issue #5515: str.format() type 'n' combined with commas and leading
5991 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005992
5993- Implement PEP 378, Format Specifier for Thousands Separator, for
5994 floats.
5995
Mark Dickinson3370cce2009-04-17 22:40:53 +00005996- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005997 1e11, not 1e12. This avoids printing 13 significant digits in
5998 situations where only 12 of them are correct. Example problem
5999 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6000 long time.)
6001
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006002- Issue #1580: On most platforms, use a 'short' float repr: for a
6003 finite float x, repr(x) now outputs a string based on the shortest
6004 sequence of decimal digits that rounds to x. Previous behaviour was
6005 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006006 Another minor difference is that the new repr switches to
6007 exponential notation at 1e16 instead of the previous 1e17; this
6008 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006009
6010 There's a new sys attribute sys.float_repr_style, which takes
6011 the value 'short' to indicate that we're using short float repr,
6012 and 'legacy' if the short float repr isn't available for one
6013 reason or another.
6014
6015 The float repr change involves incorporating David Gay's 'perfect
6016 rounding' code into the Python core (it's in Python/dtoa.c). As a
6017 secondary consequence, all string-to-float and float-to-string
6018 conversions (including all float formatting operations) will be
6019 correctly rounded on these platforms.
6020
Georg Brandl5f90d792010-08-01 22:31:05 +00006021 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006022 this change does not apply.
6023
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006024- Issue #5759: float() didn't call __float__ on str subclasses.
6025
Georg Brandlabc38772009-04-12 15:51:51 +00006026- The string.maketrans() function is deprecated; there is a new static method
6027 maketrans() on the bytes and bytearray classes. This removes confusion about
6028 the types string.maketrans() is supposed to work with, and mirrors the
6029 methods available on the str class.
6030
R. David Murraydc6da8a2009-04-09 22:16:43 +00006031- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6032 its clarity and its speed.
6033
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006034- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006035 to avoid compiler warnings.
6036
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006037- Issue #3739: The unicode-internal encoder now reports the number of characters
6038 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrouab868312009-01-10 15:40:25 +00006375- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6376 common cases are optimized thanks to a dedicated fast path and a moderate
6377 amount of loop unrolling.
6378
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006379- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6380 collecting the oldest generation) so that allocating lots of objects without
6381 destroying them does not show quadratic performance. Based on a proposal by
6382 Martin von Löwis at
6383 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6384
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006385- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006386 having been closed (for instance, a read() call could return some
6387 previously buffered data). Patch by Dmitry Vasiliev.
6388
Antoine Pitrou05608432009-01-09 18:53:14 +00006389- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6390 flag to work properly. Furthermore, when specifying -u, the text stdout
6391 and stderr streams have line-by-line buffering enabled (the default being
6392 to buffer arbitrary chunks of data).
6393
Raymond Hettinger35631532009-01-09 03:58:09 +00006394- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6395 instead of ints (reducing its size from 4 to 8 times thereby reducing
6396 Python's overall memory).
6397
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006398- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6399 an existing .py counterpart, override the co_filename attributes of all
6400 code objects if the original filename is obsolete (which can happen if the
6401 file has been renamed, moved, or if it is accessed through different paths).
6402 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6403
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006404- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6405 one byte. Also fixes the meaning of len() so that it returns the number of
6406 items, rather than the size in bytes.
6407
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006408- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6409
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006410- Issue #4747: When the terminal does not use utf-8, executing a script with
6411 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6412
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006413- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

Antoine Pitrou7ddda782009-01-01 15:35:33 +00006416- Issue #3680: Reference cycles created through a dict, set or deque iterator
6417 did not get collected.
6418
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006419- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6420 where the tp_hash and tp_dict slots are both NULL.
6421
Georg Brandlccc47b62008-12-28 11:44:14 +00006422- Issue #4759: None is now allowed as the first argument of
6423 bytearray.translate(). It was always allowed for bytes.translate().
6424
Skip Montanaro80072cb2008-12-23 03:51:14 +00006425- Added test case to ensure attempts to read from a file opened for writing
6426 fail.
6427
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006428- Issue #3106: Speedup some comparisons (str/str and int/int).

6432
Antoine Pitrou621601a2008-12-17 23:18:19 +00006433- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

6435 unreachable. Original patch by Neil Schemenauer.
6436
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006437- Issue #3439: Add a bit_length method to int.
6438
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006439- Issue #2173: When getting device encoding, check that return value of
6440 nl_langinfo is not the empty string. This was causing silent build
6441 failures on OS X.
6442
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006443- Issue #4597: Fixed several opcodes that weren't always propagating
6444 exceptions.
6445
6446- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006447 context manager returns a value that cannot be converted to a bool.
6448
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006449- Issue #4445: Replace "sizeof(PyBytesObject)" with
6450 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6451 bytes instances. On a typical machine this saves 3 bytes of memory
6452 (on average) per allocation of a bytes instance.
6453
Christian Heimesa872de52008-12-05 08:26:55 +00006454- Issue #4533: File read operation was dreadfully slow due to a slowly
6455 growing read buffer. Fixed by using the same growth rate algorithm as
6456 Python 2.x.
6457
Antoine Pitrou5504e892008-12-06 21:27:53 +00006458- Issue #4509: Various issues surrounding resize of bytearray objects to
6459 which there are buffer exports (e.g. memoryview instances).
6460
Georg Brandlf9734072008-12-07 15:30:06 +00006461- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6462 method on file objects with closefd=False. The file descriptor is still
6463 kept open but the file object behaves like a closed file. The ``FileIO``
6464 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00006466- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6467 larger than 1.

6472
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006473- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6474 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6475 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6476 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00006796- Issue #5008: When a file is opened in append mode with the new IO library,
6797 do an explicit seek to the end of file (so that e.g. tell() returns the
6798 file size rather than 0). This is consistent with the behaviour of the

6829 appropriately when it is being used via socket.makefile() objects
6830 rather than delaying the close by waiting for garbage collection to do it.
6831
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006832- Issue #1696199: Add collections.Counter() for rapid and convenient
