Ned Deily657b2de2011-06-28 19:51:30 -0700713- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
714 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
715 interpreter process. This could cause failures in non-Distutils subprocesses
716 and was unreliable since tests or user programs could modify the interpreter
717 environment after Distutils set it. Instead, have Distutils set the the
718 deployment target only in the environment of each build subprocess. It is
719 still possible to globally override the default by setting
720 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
721 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700722 was built. Also, implement the same handling in packaging.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001955- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001956 continuation line in the formatted value has no leading white space and looks

1958 is made for all headers in any serialized message at serialization time. This
1959 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002614 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002615 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002616 encoding and to encode command line arguments on this OS.

2619 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002962- Issue #10068: Global objects which have reference cycles with their module's
2963 dict are now cleared again. This causes issue #7140 to appear again.
2964
Victor Stinner257d38f2010-10-09 10:12:11 +00002965- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002966 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002967
Georg Brandl27a28582010-10-10 09:49:21 +00002968- ast.literal_eval() can now handle negative numbers. It is also a little more
2969 liberal in what it accepts without compromising the safety of the evaluation.
2970 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002971
Benjamin Peterson970d1882010-10-02 17:55:47 +00002972- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2973 result metaclasses can now be ABCs (see #9533).
2974
Victor Stinneraef57e32010-10-02 11:50:49 +00002975- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2976
Victor Stinner5593d8a2010-10-02 11:11:27 +00002977- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002978 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2979 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002980
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002981- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002982 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002983
Victor Stinner137c34c2010-09-29 10:25:54 +00002984- Issue #9979: Create function PyUnicode_AsWideCharString().
2985
Brett Cannon5305a992010-09-27 21:08:38 +00002986- Issue #7397: Mention that importlib.import_module() is probably what someone
2987 really wants to be using in __import__'s docstring.
2988
Georg Brandl27a28582010-10-10 09:49:21 +00002989- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2990 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002991
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002992- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002993 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002994
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002995- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2996
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002997- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2998 threads are still running. Instead, reinitialize the GIL on a second call to
2999 Py_Initialize().
3000
Georg Brandl27a28582010-10-10 09:49:21 +00003001- All SyntaxErrors now have a column offset and therefore a caret when the error
3002 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003003
Brett Cannonbc2eff32010-09-19 21:39:02 +00003004- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3005 module that was imported, but instead gets the module from sys.modules.
3006
Nick Coghlan37ee8502010-12-03 14:26:13 +00003007- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003008 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00003009
Georg Brandl27a28582010-10-10 09:49:21 +00003010- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3011 with a non-empty format string. This is an effort to future-proof user
3012 code. If a derived class does not currently implement __format__ but later
3013 adds its own __format__, it would most likely break user code that had
3014 supplied a format string. This will be changed to a DeprecationWaring in
3015 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003016
Antoine Pitrou1df15362010-09-13 14:16:46 +00003017- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3018 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3019 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3020
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003021- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3022 functions from the libc caused the methods .upper() and lower() to become
3023 locale aware and created subtly wrong results.
3024
Georg Brandl27a28582010-10-10 09:49:21 +00003025- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3026 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003027
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003028- Issue #4617: Previously it was illegal to delete a name from the local
3029 namespace if it occurs as a free variable in a nested block. This limitation
3030 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3031
Georg Brandl27a28582010-10-10 09:49:21 +00003032- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3033 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3034 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3035 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003036
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003037- Issue #9757: memoryview objects get a release() method to release the
3038 underlying buffer (previously this was only done when deallocating the
3039 memoryview), and gain support for the context management protocol.
3040
Antoine Pitrou079ce542010-09-08 12:37:10 +00003041- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3042 thread-local storage key.

3054 not in build_clib.
3055
Antoine Pitroudbec7802010-10-10 09:37:12 +00003056- Issue #9437: Fix building C extensions with non-default LDFLAGS.
3057
R. David Murray96fd54e2010-10-08 15:55:28 +00003058- Issue #4661: email can now parse bytes input and generate either converted
3059 7bit output or bytes output. Email version bumped to 5.1.0.
3060
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003061- Issue #1589: Add ssl.match_hostname(), to help implement server identity
3062 verification for higher-level protocols.
3063
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00003064- Issue #9759: GzipFile now raises ValueError when an operation is attempted
3065 after the file is closed. Patch by Jeffrey Finkelstein.
3066
Éric Araujo6108bf52010-10-04 23:52:37 +00003067- Issue #9042: Fix interaction of custom translation classes and caching in
3068 gettext.
3069
Éric Araujoef777bd2010-10-05 00:04:20 +00003070- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003071 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003072 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003073 replacement for old handle_accept() and avoids the user to call accept()
3074 directly.
3075
Lars Gustäbel331b8002010-10-04 15:18:47 +00003076- Issue #9065: tarfile no longer uses "root" as the default for the uname and

3080 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00003081
R. David Murray5397e862010-10-02 15:58:26 +00003082- Issue #1050268: parseaddr now correctly quotes double quote and backslash
3083 characters that appear inside quoted strings in email addresses.

Georg Brandl27a28582010-10-10 09:49:21 +00003085- Issue #10004: quoprimime no longer generates a traceback when confronted with

Georg Brandl27a28582010-10-10 09:49:21 +00003091- Issue #9360: Cleanup and improvements to the nntplib module. The API now
3092 conforms to the philosophy of bytes and unicode separation in Python 3. A
3093 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00003094
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00003095- Issue #9962: GzipFile now has the peek() method.
3096
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003097- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003098 retry the select() loop instead of bailing out. This is because select() can
3099 incorrectly report a socket as ready for reading (for example, if it received
3100 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003101
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00003102- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00003104- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00003105 received. Now sendall() properly calls signal handlers if necessary, and
3106 retries sending if these returned successfully, including on sockets with a

3136
Georg Brandl27a28582010-10-10 09:49:21 +00003137- logging: Changed LoggerAdapter implementation internally, to make it easier to
3138 subclass in a useful way.

Georg Brandl27a28582010-10-10 09:49:21 +00003147 non-blocking mode: they return None when an operation would block (instead of

Antoine Pitrou328ec742010-09-14 18:37:24 +00003159
Georg Brandl27a28582010-10-10 09:49:21 +00003160- Issue #1552: socket.socketpair() now returns regular socket.socket objects

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003180- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003181 it possible for the user to create self-referencing ordered dictionaries which
3182 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003183 approach of using weakref proxies so that reference cycles never get created
3184 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003190- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3191 environment variable to set the filesystem encoding at Python startup.
3192 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Georg Brandl27a28582010-10-10 09:49:21 +00003199- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00003202- Logging: Added QueueHandler class to facilitate logging usage with
3203 multiprocessing.
3204
Georg Brandl27a28582010-10-10 09:49:21 +00003205- Issue #9707: Rewritten reference implementation of threading.local which is
3206 friendlier towards reference cycles. This change is not normally visible
3207 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003208
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003209- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3210 still return the id of the parent process after it has exited. This process
3211 id may even have been reused by another unrelated process.
3212
Georg Brandl27a28582010-10-10 09:49:21 +00003213- Issue #9792: In case of connection failure, socket.create_connection() would
3214 swallow the exception and raise a new one, making it impossible to fetch the
3215 original errno, or to filter timeout errors. Now the original error is
3216 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003218- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3219 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3220 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003222- Updates to the random module:
3223
Georg Brandl27a28582010-10-10 09:49:21 +00003224 * Document which parts of the module are guaranteed to stay the same across
3225 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003226
Georg Brandl27a28582010-10-10 09:49:21 +00003227 * Update the seed() method to use all of the bits in a string instead of just
3228 the hash value. This makes better use of the seed value and assures the
3229 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003230
Georg Brandl27a28582010-10-10 09:49:21 +00003231 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3232 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3233 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003234
3235 * Improved documentation of arguments to randrange(). Issue #9379.

3246 writable.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00003250- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003251 unsupported operation is attempted (for example, writing to a file open only

Gregory P. Smith13b55292010-09-06 08:30:23 +00003254- hashlib has two new constant attributes: algorithms_guaranteed and
3255 algorithms_avaiable that respectively list the names of hash algorithms
3256 guaranteed to exist in all Python implementations and the names of hash
3257 algorithms available in the current process.
3258
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003259- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00003349- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3350 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00003362- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3363 now removed, since their effect was inexistent in 3.x (the default encoding is
3364 hardcoded to utf-8 and cannot be changed).

3386 return characters from the full Unicode range, even on narrow unicode builds
3387 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3388 in Python is that unicodedata.numeric() now returns the correct value for
3389 large code points, and repr() may consider more characters as printable.
3390
Victor Stinner6c00c142010-08-17 23:37:11 +00003391- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

3424 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003425
Georg Brandl649971e2010-09-05 17:06:50 +00003426- Issue #9416: Fix some issues with complex formatting where the output with no
3427 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003428
3429 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3430 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00003769- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003770 start byte and the continuation byte(s) are now considered invalid, instead of
3771 the number of bytes specified by the start byte. E.g.:
3772 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3773 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3774 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3775 returned a single u'\ufffd'.

3778 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3790 dealing with unary minus applied to a constant. The removed code was mutating
3791 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003795 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003796 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003797
Victor Stinner25e8ec42010-06-25 00:02:38 +00003798- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3799 "w*" format instead. Add tests for "w*" format.
3800
Victor Stinner06e49dd2010-06-13 18:21:50 +00003801- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003802 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003803 string formats.
3804
Georg Brandl62069d32010-07-31 08:56:11 +00003805- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003806 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3807 location of the raised exception.
3808
Victor Stinner313a1202010-06-11 23:56:51 +00003809- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3810 filenames and enable os.fsencode().
3811
Benjamin Peterson285a6892010-06-22 19:21:52 +00003812- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3813
Georg Brandl62069d32010-07-31 08:56:11 +00003814- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3815 interpreter with characters outside the Basic Multilingual Plane (higher than
3816 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003817
Georg Brandl62069d32010-07-31 08:56:11 +00003818- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3819 TypeError instead of giving a DeprecationWarning when a float is parsed using
3820 the 'L' code (for long long). (All other integer codes already raise
3821 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003822
Victor Stinner600d3be2010-06-10 12:00:55 +00003823- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3824 enable shortcuts for upper case encoding name. Add also a shortcut for
3825 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3826
Georg Brandl62069d32010-07-31 08:56:11 +00003827- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3828 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003829
3830- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003831 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003832 like bytearray.
3833
Georg Brandl62069d32010-07-31 08:56:11 +00003834- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003835 used anymore and it was never documented.
3836
Georg Brandl62069d32010-07-31 08:56:11 +00003837- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003839- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3840 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003841
Georg Brandl62069d32010-07-31 08:56:11 +00003842- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3843 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3844 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3845 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003846
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003847- Issue #8748: Fix two issues with comparisons between complex and integer
3848 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003849 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3850 (2) The comparison raised an OverflowError for large integers, leading to
3851 unpredictable exceptions when combining integers and complex objects in sets
3852 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003853
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003854- Issue #8766: Initialize _warnings module before importing the first module.
3855 Fix a crash if an empty directory called "encodings" exists in sys.path.
3856
Victor Stinner9ca9c252010-05-19 16:53:30 +00003857- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003858 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003859 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003860
Georg Brandl62069d32010-07-31 08:56:11 +00003861- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3862 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003863
Victor Stinnerae6265f2010-05-15 16:27:27 +00003864- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3865 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003866 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003867 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003868
Victor Stinner59e62db2010-05-15 13:14:32 +00003869- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003870 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003871
Victor Stinnerb744ba12010-05-15 12:27:16 +00003872- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003873 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003874 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3875
Victor Stinner0964ee12010-04-30 16:48:45 +00003876- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003877 PyUnicode_FromString() to support surrogates in the filename and use the right
3878 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003880- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3881
Georg Brandl62069d32010-07-31 08:56:11 +00003882- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003883
Benjamin Petersonfb886362010-04-24 18:21:17 +00003884- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3885 arguments.
3886
Victor Stinner14284c22010-04-23 12:02:30 +00003887- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003888 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00003982 where the right hand operand is a set of constants, by turning the set into a

3985 similar optimization already existed which turned a list of constants into a

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004154- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

4156 `va_copy`, but available on all python platforms.
4157
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004158- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4159 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

4182 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4183 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004184 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004194- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4195 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4196 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4213 gives improved memory leak detection when running under Valgrind, while taking
4214 advantage of pymalloc at other times.

4290 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004291 applications that use a lot of regular expressions and limits the impact of
4292 the performance hit anytime the cache is exceeded.

4306 defined in datetime with fast C impementation. Python implementation is based
4307 on the original python prototype for the datetime module by Tim Peters with
4308 minor modifications by the PyPy project. The test suite now tests `datetime`

4707 return a result based on the numeric values of the operands; previously they
4708 returned an arbitrary result based on the relative ordering of id(float) and
4709 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4710 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004714- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004715 argument `-` which tells it to read files to compile from stdin. Each line is

4725 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4726 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004773- subprocess.Popen now has restore_signals and start_new_session features. The
4774 default of restore_signals=True is a new behavior compared to earlier Python
4775 versions. This means that signals such as SIGPIPE are not ignored by default
4776 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00005303- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5304 directive. When the ``%z`` directive is present in the format string, an
5305 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5306 ``datetime.timezone`` instance constructed from the parsed offset. If both
5307 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5308 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005311 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5312 ``datetime.timezone``, return fixed name and UTC offset from their
5313 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5314 returns ``None``. A class attribute, ``utc`` contains an instance
5315 representing the UTC timezone. Original patch by Rafe Kaplan.

5812 (1) inf and nan strings with trailing whitespace were incorrectly
5813 rejected; (2) parsing of strings representing infinities and nans
5814 was locale aware; and (3) the interpretation of fromhex('-nan')
5815 didn't match that of float('-nan').

5918Core and Builtins
5919-----------------
5920
Mark Dickinson865e01a2009-05-07 16:37:01 +00005921- Issue #5914: Add new C API function PyOS_string_to_double, and
5922 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5923
Eric Smith741191f2009-05-06 13:08:15 +00005924- Issue #3382: float.__format__, complex.__format__, and %-formatting
5925 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5926 affects nan -> NAN and inf -> INF.
5927
Mark Hammond5a607a32009-05-06 08:04:54 +00005928- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5929 in all operations, including splitdrive, split, etc. splitunc() now issues
5930 a PendingDeprecation warning.
5931
Eric Smith63376222009-05-05 14:04:18 +00005932- Issue #5920: For float.__format__, change the behavior with the
5933 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5934 to be like 'g' but with at least one decimal point and with a
5935 default precision of 12. Previously, the behavior the same but with
5936 a default precision of 6. This more closely matches str(), and
5937 reduces surprises when adding alignment flags to the empty
5938 presentation type. This also affects the new complex.__format__ in
5939 the same way.
5940
Martin v. Löwis011e8422009-05-05 04:43:17 +00005941- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5942
R. David Murrayb18500d2009-05-04 22:59:07 +00005943- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5944 shadowed by classtype's, even if it was None. property now
5945 inserts the __doc__ into the subclass instance __dict__.
5946
Antoine Pitrou244651a2009-05-04 18:56:13 +00005947- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5948 sequences. Patch by Nick Barnes and Victor Stinner.
5949
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005950- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005951
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005952- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5953 received a new method, detach(). detach() disconnects the underlying stream
5954 from the buffer or text IO and returns it.
5955
Mark Dickinson33841c32009-05-01 15:37:04 +00005956- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5957 floats with absolute value over 1e50. Also remove length
5958 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5959 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005960
Eric Smith741191f2009-05-06 13:08:15 +00005961- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005962 format(complex(1, 2./3), '.5') now produces a sensible result.
5963
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005964- Issue #5864: Fix empty format code formatting for floats so that it
5965 never gives more than the requested number of significant digits.
5966
Eric Smith6dc46f52009-04-27 20:39:49 +00005967- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5968 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5969
Eric Smithcc32a112009-04-26 21:35:14 +00005970- Issue #5835: Deprecate PyOS_ascii_formatd.
5971
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005972- Issue #4971: Fix titlecase for characters that are their own
5973 titlecase, but not their own uppercase.
5974
Benjamin Peterson193152c2009-04-25 01:08:45 +00005975- Issue #5283: Setting __class__ in __del__ caused a segfault.
5976
Mark Dickinsonad476da2009-04-23 19:14:16 +00005977- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5978 z involves nans, infs or negative zeros.
5979
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005980- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005981
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005982- Issue #1869 (and many duplicates): make round(x, n) correctly
5983 rounded for a float x, by using the decimal <-> binary conversions
5984 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5985 consistently agrees with format(x, '.2f').
5986
Benjamin Petersonae937c02009-04-18 20:54:08 +00005987- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5988 some builtin types.
5989
Eric Smith0923d1d2009-04-16 20:16:10 +00005990- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5991
Eric Smith35e84722009-04-16 20:21:28 +00005992- Issue #5515: str.format() type 'n' combined with commas and leading
5993 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005994
5995- Implement PEP 378, Format Specifier for Thousands Separator, for
5996 floats.
5997
Mark Dickinson3370cce2009-04-17 22:40:53 +00005998- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005999 1e11, not 1e12. This avoids printing 13 significant digits in
6000 situations where only 12 of them are correct. Example problem
6001 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6002 long time.)
6003
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006004- Issue #1580: On most platforms, use a 'short' float repr: for a
6005 finite float x, repr(x) now outputs a string based on the shortest
6006 sequence of decimal digits that rounds to x. Previous behaviour was
6007 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006008 Another minor difference is that the new repr switches to
6009 exponential notation at 1e16 instead of the previous 1e17; this
6010 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006011
6012 There's a new sys attribute sys.float_repr_style, which takes
6013 the value 'short' to indicate that we're using short float repr,
6014 and 'legacy' if the short float repr isn't available for one
6015 reason or another.
6016
6017 The float repr change involves incorporating David Gay's 'perfect
6018 rounding' code into the Python core (it's in Python/dtoa.c). As a
6019 secondary consequence, all string-to-float and float-to-string
6020 conversions (including all float formatting operations) will be
6021 correctly rounded on these platforms.
6022
Georg Brandl5f90d792010-08-01 22:31:05 +00006023 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006024 this change does not apply.
6025
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006026- Issue #5759: float() didn't call __float__ on str subclasses.
6027
Georg Brandlabc38772009-04-12 15:51:51 +00006028- The string.maketrans() function is deprecated; there is a new static method
6029 maketrans() on the bytes and bytearray classes. This removes confusion about
6030 the types string.maketrans() is supposed to work with, and mirrors the
6031 methods available on the str class.
6032
R. David Murraydc6da8a2009-04-09 22:16:43 +00006033- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6034 its clarity and its speed.
6035
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006036- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006037 to avoid compiler warnings.
6038
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006039- Issue #3739: The unicode-internal encoder now reports the number of characters
6040 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrouab868312009-01-10 15:40:25 +00006377- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6378 common cases are optimized thanks to a dedicated fast path and a moderate
6379 amount of loop unrolling.
6380
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006381- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6382 collecting the oldest generation) so that allocating lots of objects without
6383 destroying them does not show quadratic performance. Based on a proposal by
6384 Martin von Löwis at
6385 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6386
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006387- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006388 having been closed (for instance, a read() call could return some
6389 previously buffered data). Patch by Dmitry Vasiliev.
6390
Antoine Pitrou05608432009-01-09 18:53:14 +00006391- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6392 flag to work properly. Furthermore, when specifying -u, the text stdout
6393 and stderr streams have line-by-line buffering enabled (the default being
6394 to buffer arbitrary chunks of data).
6395
Raymond Hettinger35631532009-01-09 03:58:09 +00006396- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6397 instead of ints (reducing its size from 4 to 8 times thereby reducing
6398 Python's overall memory).
6399
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006400- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6401 an existing .py counterpart, override the co_filename attributes of all
6402 code objects if the original filename is obsolete (which can happen if the
6403 file has been renamed, moved, or if it is accessed through different paths).
6404 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6405
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006406- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6407 one byte. Also fixes the meaning of len() so that it returns the number of
6408 items, rather than the size in bytes.
6409
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006410- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6411
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006412- Issue #4747: When the terminal does not use utf-8, executing a script with
6413 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6414
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006415- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6416 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006417
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006418- Issue #3680: Reference cycles created through a dict, set or deque iterator
6419 did not get collected.
6420
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006421- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6422 where the tp_hash and tp_dict slots are both NULL.
6423
Georg Brandlccc47b62008-12-28 11:44:14 +00006424- Issue #4759: None is now allowed as the first argument of
6425 bytearray.translate(). It was always allowed for bytes.translate().
6426
Skip Montanaro80072cb2008-12-23 03:51:14 +00006427- Added test case to ensure attempts to read from a file opened for writing
6428 fail.
6429
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006430- Issue #3106: Speedup some comparisons (str/str and int/int).

6434
Antoine Pitrou621601a2008-12-17 23:18:19 +00006435- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6436 print elapsed times, not only when some objects are uncollectable /
6437 unreachable. Original patch by Neil Schemenauer.
6438
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006439- Issue #3439: Add a bit_length method to int.
6440
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006441- Issue #2173: When getting device encoding, check that return value of
6442 nl_langinfo is not the empty string. This was causing silent build
6443 failures on OS X.
6444
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006445- Issue #4597: Fixed several opcodes that weren't always propagating
6446 exceptions.
6447
6448- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006449 context manager returns a value that cannot be converted to a bool.
6450
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006451- Issue #4445: Replace "sizeof(PyBytesObject)" with
6452 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6453 bytes instances. On a typical machine this saves 3 bytes of memory
6454 (on average) per allocation of a bytes instance.
6455
Christian Heimesa872de52008-12-05 08:26:55 +00006456- Issue #4533: File read operation was dreadfully slow due to a slowly
6457 growing read buffer. Fixed by using the same growth rate algorithm as
6458 Python 2.x.
6459
Antoine Pitrou5504e892008-12-06 21:27:53 +00006460- Issue #4509: Various issues surrounding resize of bytearray objects to
6461 which there are buffer exports (e.g. memoryview instances).
6462
Georg Brandlf9734072008-12-07 15:30:06 +00006463- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6464 method on file objects with closefd=False. The file descriptor is still
6465 kept open but the file object behaves like a closed file. The ``FileIO``
6466 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006467
Antoine Pitroubc420402008-12-07 20:14:49 +00006468- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6469 larger than 1.

6474
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006475- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6476 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6477 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6478 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00006798- Issue #5008: When a file is opened in append mode with the new IO library,
6799 do an explicit seek to the end of file (so that e.g. tell() returns the

6831 appropriately when it is being used via socket.makefile() objects
6832 rather than delaying the close by waiting for garbage collection to do it.
6833
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006834- Issue #1696199: Add collections.Counter() for rapid and convenient
