108 (See whatsnew/3.3), and the documentation has been updated extensively.
109 The ndarray test object from _testbuffer.c implements all aspects of
110 PEP-3118, so further development towards the complete implementation

186
Antoine Pitroue0e27352011-12-15 14:31:28 +0100187- Fix OSError.__init__ and OSError.__new__ so that each of them can be

206 sys module entries are now set to None (instead of an unusable file object).
207
Antoine Pitrouf0effe62011-11-26 01:11:02 +0100208- Issue #11849: Ensure that free()d memory arenas are really released

Ned Deily99377482012-02-10 13:01:08 +0100682- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
683 Distutils-based packages with C extension modules may fail because
684 Apple has removed gcc-4.2, the version used to build python.org
685 64-bit/32-bit Pythons. If the user does not explicitly override
686 the default C compiler by setting the CC environment variable,
687 Distutils will now attempt to compile extension modules with clang
688 if gcc-4.2 is required but not found. Also as a convenience, if
689 the user does explicitly set CC, substitute its value as the default
690 compiler in the Distutils LDSHARED configuration variable for OS X.
691 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
692 SDK, neither of which are available in Xcode 4. This change does not
693 attempt to override settings to support their use with Xcode 4.)

1272 Condition, etc.) used to be factory functions returning instances of hidden

Antoine Pitroud42c1d02011-07-23 21:50:21 +02001306 a read1() method), and add a *write_through* parameter to mandate

Ned Deily657b2de2011-06-28 19:51:30 -07001420- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1421 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1422 interpreter process. This could cause failures in non-Distutils subprocesses
1423 and was unreliable since tests or user programs could modify the interpreter
1424 environment after Distutils set it. Instead, have Distutils set the the
1425 deployment target only in the environment of each build subprocess. It is
1426 still possible to globally override the default by setting
1427 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1428 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001429 was built. Also, implement the same handling in packaging.

2245
Nadeem Vawda3c01d162011-08-01 23:48:26 +02002246- Issue #11651: Improve the Makefile test targets to run more of the test suite
2247 more quickly. The --multiprocess option is now enabled by default, reducing
2248 the amount of time needed to run the tests. "make test" and "make quicktest"
2249 now include some resource-intensive tests, but no longer run the test suite
2250 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02002251 an easy platform-independent way to run test suite with sensible defaults.

Antoine Pitrouf83e4ac2011-07-29 23:57:10 +02002259- Issue #12626: In regrtest, allow to filter tests using a glob filter
2260 with the ``-m`` (or ``--match``) option. This works with all test cases
2261 using the unittest module. This is useful with long test suites
2262 such as test_io or test_subprocess.

2266 (or ``-G``) option to regrtest. This is useful with long test suites
2267 such as test_io or test_subprocess.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00003384 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00003385 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00003386 encoding and to encode command line arguments on this OS.

3389 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003767- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3768 threads are still running. Instead, reinitialize the GIL on a second call to
3769 Py_Initialize().
3770
Georg Brandl27a28582010-10-10 09:49:21 +00003771- All SyntaxErrors now have a column offset and therefore a caret when the error
3772 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003773
Brett Cannonbc2eff32010-09-19 21:39:02 +00003774- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3775 module that was imported, but instead gets the module from sys.modules.
3776
Nick Coghlan37ee8502010-12-03 14:26:13 +00003777- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003778 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00003780- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3781 with a non-empty format string. This is an effort to future-proof user
3782 code. If a derived class does not currently implement __format__ but later
3783 adds its own __format__, it would most likely break user code that had
3784 supplied a format string. This will be changed to a DeprecationWaring in
3785 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003786
Antoine Pitrou1df15362010-09-13 14:16:46 +00003787- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3788 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3789 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3790
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003791- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3792 functions from the libc caused the methods .upper() and lower() to become
3793 locale aware and created subtly wrong results.
3794
Georg Brandl27a28582010-10-10 09:49:21 +00003795- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3796 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003797
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003798- Issue #4617: Previously it was illegal to delete a name from the local
3799 namespace if it occurs as a free variable in a nested block. This limitation
3800 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3801
Georg Brandl27a28582010-10-10 09:49:21 +00003802- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3803 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3804 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3805 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003807- Issue #9757: memoryview objects get a release() method to release the
3808 underlying buffer (previously this was only done when deallocating the
3809 memoryview), and gain support for the context management protocol.
3810
Antoine Pitrou079ce542010-09-08 12:37:10 +00003811- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3812 thread-local storage key.

3836
Éric Araujo6108bf52010-10-04 23:52:37 +00003837- Issue #9042: Fix interaction of custom translation classes and caching in
3838 gettext.
3839
Éric Araujoef777bd2010-10-05 00:04:20 +00003840- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003841 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003842 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003843 replacement for old handle_accept() and avoids the user to call accept()
3844 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00003846- Issue #9065: tarfile no longer uses "root" as the default for the uname and

3862 conforms to the philosophy of bytes and unicode separation in Python 3. A
3863 test suite has also been added.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003867- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003868 retry the select() loop instead of bailing out. This is because select() can
3869 incorrectly report a socket as ready for reading (for example, if it received
3870 some data with an invalid checksum).

Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00003872- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

3906
Georg Brandl27a28582010-10-10 09:49:21 +00003907- logging: Changed LoggerAdapter implementation internally, to make it easier to
3908 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00003909
Vinay Sajipc84f0162010-09-21 11:25:39 +00003910- logging: hasHandlers method was added to Logger, and isEnabledFor,
3911 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
3912 LoggerAdapter was introduced into the unit tests for logging.

Florent Xiclunaeb19dce2010-09-18 23:34:07 +00003914- Issue #1686: Fix string.Template when overriding the pattern attribute.
3915
Antoine Pitrou98b46702010-09-18 22:59:00 +00003916- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003917 non-blocking mode: they return None when an operation would block (instead of
3918 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00003919
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00003920- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
3921 another kind.

Georg Brandl27a28582010-10-10 09:49:21 +00003927- Issue #9854: The default read() implementation in io.RawIOBase now handles
3928 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00003929
Georg Brandl27a28582010-10-10 09:49:21 +00003930- Issue #1552: socket.socketpair() now returns regular socket.socket objects
3931 supporting the whole socket API (rather than the "raw" _socket.socket
3932 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00003933
Georg Brandl27a28582010-10-10 09:49:21 +00003934- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Éric Araujod8c73c62011-03-21 03:15:22 +01003937- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00003938 them handle recursive calls within the same thread.

3946
Georg Brandl27a28582010-10-10 09:49:21 +00003947- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +00003949
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003950- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003951 it possible for the user to create self-referencing ordered dictionaries which
3952 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003953 approach of using weakref proxies so that reference cycles never get created
3954 in the first place.
3955
Victor Stinnercb043522010-09-10 23:49:04 +00003956- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3957 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00003958 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00003959
Georg Brandl27a28582010-10-10 09:49:21 +00003960- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3961 environment variable to set the filesystem encoding at Python startup.
3962 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3963 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003964
Georg Brandl27a28582010-10-10 09:49:21 +00003965- Issue #9410: Various optimizations to the pickle module, leading to speedups
3966 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
3967 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00003968
Georg Brandl27a28582010-10-10 09:49:21 +00003969- The pprint module now supports printing OrderedDicts in their given order
3970 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00003971
Vinay Sajip121a1c42010-09-08 10:46:15 +00003972- Logging: Added QueueHandler class to facilitate logging usage with
3973 multiprocessing.
3974
Georg Brandl27a28582010-10-10 09:49:21 +00003975- Issue #9707: Rewritten reference implementation of threading.local which is
3976 friendlier towards reference cycles. This change is not normally visible
3977 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003978
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003979- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3980 still return the id of the parent process after it has exited. This process
3981 id may even have been reused by another unrelated process.
3982
Georg Brandl27a28582010-10-10 09:49:21 +00003983- Issue #9792: In case of connection failure, socket.create_connection() would
3984 swallow the exception and raise a new one, making it impossible to fetch the
3985 original errno, or to filter timeout errors. Now the original error is
3986 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00003987
Georg Brandl27a28582010-10-10 09:49:21 +00003988- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3989 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3990 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003992- Updates to the random module:
3993
Georg Brandl27a28582010-10-10 09:49:21 +00003994 * Document which parts of the module are guaranteed to stay the same across
3995 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003996
Georg Brandl27a28582010-10-10 09:49:21 +00003997 * Update the seed() method to use all of the bits in a string instead of just
3998 the hash value. This makes better use of the seed value and assures the
3999 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00004000
Georg Brandl27a28582010-10-10 09:49:21 +00004001 * Improved the random()-->integer algorithm used in choice(), shuffle(),
4002 sample(), randrange(), and randint(). Formerly, it used int(n*random())
4003 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00004004
4005 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00004007- collections.OrderedDict now supports a new method for repositioning keys to
4008 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00004009
Georg Brandl27a28582010-10-10 09:49:21 +00004010- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test

4156 return characters from the full Unicode range, even on narrow unicode builds
4157 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
4158 in Python is that unicodedata.numeric() now returns the correct value for
4159 large code points, and repr() may consider more characters as printable.

4197 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00004198
4199 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

4538
Ezio Melotti57221d02010-07-01 07:32:02 +00004539- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004540 start byte and the continuation byte(s) are now considered invalid, instead of
4541 the number of bytes specified by the start byte. E.g.:
4542 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4543 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4544 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4545 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00004546
Georg Brandl62069d32010-07-31 08:56:11 +00004547- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
4548 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00004559- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
4560 dealing with unary minus applied to a constant. The removed code was mutating
4561 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00004562
Victor Stinner554f3f02010-06-16 23:33:54 +00004563- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00004564 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00004565 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004566 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00004567
Victor Stinner25e8ec42010-06-25 00:02:38 +00004568- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
4569 "w*" format instead. Add tests for "w*" format.
4570
Victor Stinner06e49dd2010-06-13 18:21:50 +00004571- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00004572 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00004573 string formats.
4574
Georg Brandl62069d32010-07-31 08:56:11 +00004575- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004576 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4577 location of the raised exception.
4578
Victor Stinner313a1202010-06-11 23:56:51 +00004579- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4580 filenames and enable os.fsencode().
4581
Benjamin Peterson285a6892010-06-22 19:21:52 +00004582- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
4583
Georg Brandl62069d32010-07-31 08:56:11 +00004584- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
4585 interpreter with characters outside the Basic Multilingual Plane (higher than
4586 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00004587
Georg Brandl62069d32010-07-31 08:56:11 +00004588- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4589 TypeError instead of giving a DeprecationWarning when a float is parsed using
4590 the 'L' code (for long long). (All other integer codes already raise
4591 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004592
Victor Stinner600d3be2010-06-10 12:00:55 +00004593- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4594 enable shortcuts for upper case encoding name. Add also a shortcut for
4595 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4596
Georg Brandl62069d32010-07-31 08:56:11 +00004597- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4598 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004599
4600- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004601 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004602 like bytearray.
4603
Georg Brandl62069d32010-07-31 08:56:11 +00004604- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004605 used anymore and it was never documented.
4606
Georg Brandl62069d32010-07-31 08:56:11 +00004607- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00004608
Georg Brandl62069d32010-07-31 08:56:11 +00004609- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4610 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004611
Georg Brandl62069d32010-07-31 08:56:11 +00004612- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4613 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4614 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4615 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004616
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004617- Issue #8748: Fix two issues with comparisons between complex and integer
4618 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004619 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4620 (2) The comparison raised an OverflowError for large integers, leading to
4621 unpredictable exceptions when combining integers and complex objects in sets
4622 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004623
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004624- Issue #8766: Initialize _warnings module before importing the first module.
4625 Fix a crash if an empty directory called "encodings" exists in sys.path.
4626
Victor Stinner9ca9c252010-05-19 16:53:30 +00004627- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004628 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004629 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004630
Georg Brandl62069d32010-07-31 08:56:11 +00004631- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4632 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004633
Victor Stinnerae6265f2010-05-15 16:27:27 +00004634- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4635 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004636 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004637 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004638
Victor Stinner59e62db2010-05-15 13:14:32 +00004639- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004640 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004641
Victor Stinnerb744ba12010-05-15 12:27:16 +00004642- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004643 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004644 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4645
Victor Stinner0964ee12010-04-30 16:48:45 +00004646- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004647 PyUnicode_FromString() to support surrogates in the filename and use the right
4648 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004649
Georg Brandl8569e582010-05-19 20:57:08 +00004650- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4651
Georg Brandl62069d32010-07-31 08:56:11 +00004652- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004653
Benjamin Petersonfb886362010-04-24 18:21:17 +00004654- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4655 arguments.
4656
Victor Stinner14284c22010-04-23 12:02:30 +00004657- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004658 indirectly Python signal handlers anymore because mywrite() ignores exceptions
4659 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00004663
Georg Brandl62069d32010-07-31 08:56:11 +00004664- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4665 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004666
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004667- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004668 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

4755 similar optimization already existed which turned a list of constants into a

Antoine Pitrou3060c452010-08-13 16:27:38 +00005059 simply clearing the entire cache on overflow to forgetting the least recently
5060 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00005061 applications that use a lot of regular expressions and limits the impact of
5062 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00005476- Issue #2531: Comparison operations between floats and Decimal instances now
5477 return a result based on the numeric values of the operands; previously they
5478 returned an arbitrary result based on the relative ordering of id(float) and
5479 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
5480 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00005484- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005485 argument `-` which tells it to read files to compile from stdin. Each line is
5486 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandl62069d32010-07-31 08:56:11 +00005493- Comparisons using one of <, <=, >, >= between a complex instance and a
5494 Fractions instance now raise TypeError instead of returning True/False. This
5495 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5496 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005539- The internals of the subprocess module on POSIX systems have been replaced by
5540 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5541 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00005543- subprocess.Popen now has restore_signals and start_new_session features. The
5544 default of restore_signals=True is a new behavior compared to earlier Python
5545 versions. This means that signals such as SIGPIPE are not ignored by default
5546 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00005638 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
5639 archive. The new implementation is significantly faster and can be wrapped in
5640 a :class:`io.BufferedReader` object for more speedups. It also solves an
5641 issue where interleaved calls to `read()` and `readline()` give wrong results.
5642 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00006039- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00006040 compared to other unix systems. In particular, os.getgroups() does not reflect
6041 any changes made using os.setgroups() but basicly always returns the same
6042 information as the id command. os.getgroups() can now return more than 16
6043 groups on MacOSX.

Antoine Pitrouc3ee1662009-05-23 16:02:33 +00006619- Issue #1983: Fix functions taking or returning a process identifier to use
6620 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
6621 a process identifier type wider than the standard C integer type.

6634
Antoine Pitroue4501852009-05-14 18:55:55 +00006635- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6636 library. This means, for example, that opening an UTF-16 text file in
6637 append mode doesn't add a BOM at the end of the file if the file isn't
6638 empty.
6639
R. David Murray74b89242009-05-13 17:33:03 +00006640- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
6641 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
6642 corrects a pydoc regression.
6643
Georg Brandl5f90d792010-08-01 22:31:05 +00006644- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00006645 now it does. This also means getfp method now returns the real fp.

6688Core and Builtins
6689-----------------
6690
Mark Dickinson865e01a2009-05-07 16:37:01 +00006691- Issue #5914: Add new C API function PyOS_string_to_double, and
6692 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6693
Eric Smith741191f2009-05-06 13:08:15 +00006694- Issue #3382: float.__format__, complex.__format__, and %-formatting
6695 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6696 affects nan -> NAN and inf -> INF.
6697
Mark Hammond5a607a32009-05-06 08:04:54 +00006698- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6699 in all operations, including splitdrive, split, etc. splitunc() now issues
6700 a PendingDeprecation warning.
6701
Eric Smith63376222009-05-05 14:04:18 +00006702- Issue #5920: For float.__format__, change the behavior with the
6703 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6704 to be like 'g' but with at least one decimal point and with a
6705 default precision of 12. Previously, the behavior the same but with
6706 a default precision of 6. This more closely matches str(), and
6707 reduces surprises when adding alignment flags to the empty
6708 presentation type. This also affects the new complex.__format__ in
6709 the same way.
6710
Martin v. Löwis011e8422009-05-05 04:43:17 +00006711- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6712
R. David Murrayb18500d2009-05-04 22:59:07 +00006713- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6714 shadowed by classtype's, even if it was None. property now
6715 inserts the __doc__ into the subclass instance __dict__.
6716
Antoine Pitrou244651a2009-05-04 18:56:13 +00006717- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6718 sequences. Patch by Nick Barnes and Victor Stinner.
6719
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006720- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006721
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006722- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6723 received a new method, detach(). detach() disconnects the underlying stream
6724 from the buffer or text IO and returns it.
6725
Mark Dickinson33841c32009-05-01 15:37:04 +00006726- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6727 floats with absolute value over 1e50. Also remove length
6728 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6729 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006730
Eric Smith741191f2009-05-06 13:08:15 +00006731- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006732 format(complex(1, 2./3), '.5') now produces a sensible result.
6733
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006734- Issue #5864: Fix empty format code formatting for floats so that it
6735 never gives more than the requested number of significant digits.
6736
Eric Smith6dc46f52009-04-27 20:39:49 +00006737- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6738 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6739
Eric Smithcc32a112009-04-26 21:35:14 +00006740- Issue #5835: Deprecate PyOS_ascii_formatd.
6741
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006742- Issue #4971: Fix titlecase for characters that are their own
6743 titlecase, but not their own uppercase.
6744
Benjamin Peterson193152c2009-04-25 01:08:45 +00006745- Issue #5283: Setting __class__ in __del__ caused a segfault.
6746
Mark Dickinsonad476da2009-04-23 19:14:16 +00006747- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6748 z involves nans, infs or negative zeros.
6749
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006750- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006751
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006752- Issue #1869 (and many duplicates): make round(x, n) correctly
6753 rounded for a float x, by using the decimal <-> binary conversions
6754 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6755 consistently agrees with format(x, '.2f').
6756
Benjamin Petersonae937c02009-04-18 20:54:08 +00006757- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6758 some builtin types.
6759
Eric Smith0923d1d2009-04-16 20:16:10 +00006760- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6761
Eric Smith35e84722009-04-16 20:21:28 +00006762- Issue #5515: str.format() type 'n' combined with commas and leading
6763 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006764
6765- Implement PEP 378, Format Specifier for Thousands Separator, for
6766 floats.
6767
Mark Dickinson3370cce2009-04-17 22:40:53 +00006768- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006769 1e11, not 1e12. This avoids printing 13 significant digits in
6770 situations where only 12 of them are correct. Example problem
6771 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6772 long time.)
6773
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006774- Issue #1580: On most platforms, use a 'short' float repr: for a
6775 finite float x, repr(x) now outputs a string based on the shortest
6776 sequence of decimal digits that rounds to x. Previous behaviour was
6777 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006778 Another minor difference is that the new repr switches to
6779 exponential notation at 1e16 instead of the previous 1e17; this
6780 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006781
6782 There's a new sys attribute sys.float_repr_style, which takes
6783 the value 'short' to indicate that we're using short float repr,
6784 and 'legacy' if the short float repr isn't available for one
6785 reason or another.
6786
6787 The float repr change involves incorporating David Gay's 'perfect
6788 rounding' code into the Python core (it's in Python/dtoa.c). As a
6789 secondary consequence, all string-to-float and float-to-string
6790 conversions (including all float formatting operations) will be
6791 correctly rounded on these platforms.
6792
Georg Brandl5f90d792010-08-01 22:31:05 +00006793 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006794 this change does not apply.
6795
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006796- Issue #5759: float() didn't call __float__ on str subclasses.
6797
Georg Brandlabc38772009-04-12 15:51:51 +00006798- The string.maketrans() function is deprecated; there is a new static method
6799 maketrans() on the bytes and bytearray classes. This removes confusion about
6800 the types string.maketrans() is supposed to work with, and mirrors the
6801 methods available on the str class.
6802
R. David Murraydc6da8a2009-04-09 22:16:43 +00006803- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6804 its clarity and its speed.
6805
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006806- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006807 to avoid compiler warnings.
6808
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006809- Issue #3739: The unicode-internal encoder now reports the number of characters
6810 consumed like any other encoder (instead of the number of bytes).

6948
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006949- Issue #5499: The 'c' code for argument parsing functions now only accepts a
6950 byte, and the 'C' code only accepts a unicode character.
6951
Georg Brandl406b3d82009-04-11 21:24:37 +00006952- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
6953 when hitting the recursion limit under certain circumstances.
6954
Brett Cannon0759dd62009-04-01 18:13:07 +00006955- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
6956

6958 insufficient checks in accessors of Exception.__context__.
6959
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006960- Issue #5604: non-ASCII characters in module name passed to
6961 imp.find_module() were converted to UTF-8 while the path is
6962 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006966- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6967 the end sys.path, for compatibility with the system install of Python.
6968
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006969- Issue #4688: Add a heuristic so that tuples and dicts containing only
6970 untrackable objects are not tracked by the garbage collector. This can
6971 reduce the size of collections and therefore the garbage collection overhead
6972 on long-running programs, depending on their particular use of datatypes.
6973
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006974- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

6986 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6987 and sizeof(Py_UNICODE) == 2.
6988
Eric Smith8ec90442009-03-14 12:29:34 +00006989- Issue #5237: Allow auto-numbered fields in str.format(). For

6991
Antoine Pitrou652e7072009-03-13 19:25:20 +00006992- Issue #5392: when a very low recursion limit was set, the interpreter would
6993 abort with a fatal error after the recursion limit was hit twice.
6994
Matthias Klose042f1332009-04-04 14:32:42 +00006995- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Lars Gustäbel42e00912009-03-22 20:34:29 +00007042- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
7043 forever on incomplete input. That caused tarfile.open() to hang when used
7044 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
7045 partial bzip2 compressed data.
7046
Mark Dickinson79f52032009-03-17 23:12:51 +00007047- Issue #2110: Add support for thousands separator and 'n' type

7115 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
7116 evaluation loop is compiled with a new dispatch mechanism which gives
7117 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00007132- Issue #4935: The overflow checking code in the expandtabs() method common
7133 to str, bytes and bytearray could be optimized away by the compiler, letting
7134 the interpreter segfault instead of raising an error.
7135
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00007136- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00007158 having been closed (for instance, a read() call could return some
7159 previously buffered data). Patch by Dmitry Vasiliev.
7160
Antoine Pitrou05608432009-01-09 18:53:14 +00007161- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
7162 flag to work properly. Furthermore, when specifying -u, the text stdout
7163 and stderr streams have line-by-line buffering enabled (the default being
7164 to buffer arbitrary chunks of data).
7165
Raymond Hettinger35631532009-01-09 03:58:09 +00007166- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
7167 instead of ints (reducing its size from 4 to 8 times thereby reducing
7168 Python's overall memory).
7169
Antoine Pitroud35cbf62009-01-06 19:02:24 +00007170- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
7171 an existing .py counterpart, override the co_filename attributes of all
7172 code objects if the original filename is obsolete (which can happen if the
7173 file has been renamed, moved, or if it is accessed through different paths).
7174 Patch by Ziga Seilnacht and Jean-Paul Calderone.
7175
Antoine Pitrouc3b39242009-01-03 16:59:18 +00007176- Issue #4580: Fix slicing of memoryviews when the item size is greater than
7177 one byte. Also fixes the meaning of len() so that it returns the number of
7178 items, rather than the size in bytes.
7179
Martin v. Löwis5c88d812009-01-02 20:47:48 +00007180- Issue #4075: Use OutputDebugStringW in Py_FatalError.

7567
Antoine Pitrou08838b62009-01-21 00:55:13 +00007568- Issue #5008: When a file is opened in append mode with the new IO library,
7569 do an explicit seek to the end of file (so that e.g. tell() returns the
7570 file size rather than 0). This is consistent with the behaviour of the

7601 appropriately when it is being used via socket.makefile() objects
7602 rather than delaying the close by waiting for garbage collection to do it.
7603
Raymond Hettingerb8baf632009-01-14 02:20:07 +00007604- Issue #1696199: Add collections.Counter() for rapid and convenient
