Ned Deily657b2de2011-06-28 19:51:30 -0700630- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
631 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
632 interpreter process. This could cause failures in non-Distutils subprocesses
633 and was unreliable since tests or user programs could modify the interpreter
634 environment after Distutils set it. Instead, have Distutils set the the
635 deployment target only in the environment of each build subprocess. It is
636 still possible to globally override the default by setting
637 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
638 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700639 was built. Also, implement the same handling in packaging.

1708 files in binary mode, using the email package's binary support to parse
1709 arbitrary email messages. StringIO and text file input is deprecated,
1710 and string input fails early if non-ASCII characters are used, where

1739 keyword-only argument. The preceding positional argument was deprecated,
1740 so it made no sense to add filter as a positional argument.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00001755 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1756 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)

1767- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1768 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1769 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00001770
1771- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001772 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001773 that for incoming headers which makes this behaviour now consistent in
1774 both incoming and outgoing direction.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002529 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002530 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002531 encoding and to encode command line arguments on this OS.

2534 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson230b2062010-10-16 03:45:45 +00002537- Issue #9997: Don't let the name "top" have special significance in scope
2538 resolution.

2926 with a non-empty format string. This is an effort to future-proof user
2927 code. If a derived class does not currently implement __format__ but later
2928 adds its own __format__, it would most likely break user code that had
2929 supplied a format string. This will be changed to a DeprecationWaring in
2930 Python 3.3 and it will be an error in Python 3.4.

Georg Brandl27a28582010-10-10 09:49:21 +00002947- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2948 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2949 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2950 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002985- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002986 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002987 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002988 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003013 retry the select() loop instead of bailing out. This is because select() can
3014 incorrectly report a socket as ready for reading (for example, if it received
3015 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003095- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003096 it possible for the user to create self-referencing ordered dictionaries which
3097 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003098 approach of using weakref proxies so that reference cycles never get created
3099 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00003101- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00003105- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3106 environment variable to set the filesystem encoding at Python startup.
3107 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3108 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00003114- The pprint module now supports printing OrderedDicts in their given order

3119
Georg Brandl27a28582010-10-10 09:49:21 +00003120- Issue #9707: Rewritten reference implementation of threading.local which is
3121 friendlier towards reference cycles. This change is not normally visible
3122 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003123
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003124- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3125 still return the id of the parent process after it has exited. This process
3126 id may even have been reused by another unrelated process.
3127
Georg Brandl27a28582010-10-10 09:49:21 +00003128- Issue #9792: In case of connection failure, socket.create_connection() would
3129 swallow the exception and raise a new one, making it impossible to fetch the
3130 original errno, or to filter timeout errors. Now the original error is
3131 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003137- Updates to the random module:
3138
Georg Brandl27a28582010-10-10 09:49:21 +00003139 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003142 * Update the seed() method to use all of the bits in a string instead of just
3143 the hash value. This makes better use of the seed value and assures the
3144 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003145
Georg Brandl27a28582010-10-10 09:49:21 +00003146 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3147 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3148 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003149
3150 * Improved documentation of arguments to randrange(). Issue #9379.

3171 guaranteed to exist in all Python implementations and the names of hash
3172 algorithms available in the current process.
3173

3301 return characters from the full Unicode range, even on narrow unicode builds
3302 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Georg Brandl649971e2010-09-05 17:06:50 +00003330- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3331 use PyUnicode_FromFormatV() to format the warning message.

3339 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003340
Georg Brandl649971e2010-09-05 17:06:50 +00003341- Issue #9416: Fix some issues with complex formatting where the output with no
3342 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003343
3344 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3345 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3674Core and Builtins
3675-----------------
3676
Victor Stinner8182b712010-07-28 00:40:58 +00003677- Issue #8991: convertbuffer() rejects discontigious buffers.
3678
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003679- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3680 compiler.
3681
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003682- Issue #8413: structsequence now subclasses tuple.
3683
Ezio Melotti57221d02010-07-01 07:32:02 +00003684- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003685 start byte and the continuation byte(s) are now considered invalid, instead of
3686 the number of bytes specified by the start byte. E.g.:
3687 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3688 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3689 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3690 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003691
Georg Brandl62069d32010-07-31 08:56:11 +00003692- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3693 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003694
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003695- Be more specific in error messages about positional arguments.
3696
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003697- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3698 objects, as described in the documentation.
3699
Victor Stinner0fe25a42010-06-17 23:08:50 +00003700- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +00003701 Fix the encoding of the modules filename. Patch written by Amaury Forgeot

Victor Stinner0fe25a42010-06-17 23:08:50 +00003703
Georg Brandl62069d32010-07-31 08:56:11 +00003704- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3705 dealing with unary minus applied to a constant. The removed code was mutating
3706 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003707
Victor Stinner554f3f02010-06-16 23:33:54 +00003708- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003709 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003710 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003711 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003712
Victor Stinner25e8ec42010-06-25 00:02:38 +00003713- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3714 "w*" format instead. Add tests for "w*" format.
3715
Victor Stinner06e49dd2010-06-13 18:21:50 +00003716- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003717 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003718 string formats.
3719
Georg Brandl62069d32010-07-31 08:56:11 +00003720- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003721 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3722 location of the raised exception.
3723
Victor Stinner313a1202010-06-11 23:56:51 +00003724- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3725 filenames and enable os.fsencode().
3726
Benjamin Peterson285a6892010-06-22 19:21:52 +00003727- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3728
Georg Brandl62069d32010-07-31 08:56:11 +00003729- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3730 interpreter with characters outside the Basic Multilingual Plane (higher than
3731 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003732
Georg Brandl62069d32010-07-31 08:56:11 +00003733- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3734 TypeError instead of giving a DeprecationWarning when a float is parsed using
3735 the 'L' code (for long long). (All other integer codes already raise
3736 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003737
Victor Stinner600d3be2010-06-10 12:00:55 +00003738- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3739 enable shortcuts for upper case encoding name. Add also a shortcut for
3740 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3741
Georg Brandl62069d32010-07-31 08:56:11 +00003742- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3743 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003744
3745- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003746 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003747 like bytearray.
3748
Georg Brandl62069d32010-07-31 08:56:11 +00003749- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003750 used anymore and it was never documented.
3751
Georg Brandl62069d32010-07-31 08:56:11 +00003752- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003753
Georg Brandl62069d32010-07-31 08:56:11 +00003754- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3755 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003756
Georg Brandl62069d32010-07-31 08:56:11 +00003757- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3758 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3759 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3760 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003761
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003762- Issue #8748: Fix two issues with comparisons between complex and integer
3763 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003764 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3765 (2) The comparison raised an OverflowError for large integers, leading to
3766 unpredictable exceptions when combining integers and complex objects in sets
3767 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003768
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003769- Issue #8766: Initialize _warnings module before importing the first module.
3770 Fix a crash if an empty directory called "encodings" exists in sys.path.
3771
Victor Stinner9ca9c252010-05-19 16:53:30 +00003772- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003773 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003774 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003775
Georg Brandl62069d32010-07-31 08:56:11 +00003776- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3777 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003778
Victor Stinnerae6265f2010-05-15 16:27:27 +00003779- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3780 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003781 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003782 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003783
Victor Stinner59e62db2010-05-15 13:14:32 +00003784- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003785 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003786
Victor Stinnerb744ba12010-05-15 12:27:16 +00003787- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003788 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003789 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3790
Victor Stinner0964ee12010-04-30 16:48:45 +00003791- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003792 PyUnicode_FromString() to support surrogates in the filename and use the right
3793 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003794
Georg Brandl8569e582010-05-19 20:57:08 +00003795- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3796
Georg Brandl62069d32010-07-31 08:56:11 +00003797- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003798
Benjamin Petersonfb886362010-04-24 18:21:17 +00003799- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3800 arguments.
3801
Victor Stinner14284c22010-04-23 12:02:30 +00003802- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003803 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3804 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00003806- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00003807 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00003808
Georg Brandl62069d32010-07-31 08:56:11 +00003809- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3810 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003811
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003812- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003813 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3814 compared to the dynamic memory allocation fallback. Patch by Charles-François
3815 Natali.

3893 crash in many places because of the PyByteArray_AS_STRING() macro returning
3894 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003896- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003897 where the right hand operand is a set of constants, by turning the set into a
3898 frozenset and pre-building it as a constant. The comparison operation is made
3899 against the constant instead of building a new set each time it is executed (a
3900 similar optimization already existed which turned a list of constants into a
3901 pre-built tuple). Patch and additional tests by Dave Malcolm.

3908 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3909 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3910 parsing certain long numeric strings corresponding to subnormal values, (3) a

3912 of flaws that could lead to incorrectly rounded results.

3927 of integers: the result of a/b is now correctly rounded for ints a and b (at
3928 least on IEEE 754 platforms), and in particular does not depend on the
3929 internal representation of an int.

4205 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004206 applications that use a lot of regular expressions and limits the impact of
4207 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00004587- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004588 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00004607- Issue #8257: The Decimal construct now accepts a float instance directly,
4608 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004609
4610 >>> Decimal(1.1)
4611 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004616- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4617 InvalidOperation instead of returning False. (Comparisons involving a quiet
4618 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4619 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004621- Issue #2531: Comparison operations between floats and Decimal instances now
4622 return a result based on the numeric values of the operands; previously they
4623 returned an arbitrary result based on the relative ordering of id(float) and
4624 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4625 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004626
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004627- Added a subtract() method to collections.Counter().
4628
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004629- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004630 argument `-` which tells it to read files to compile from stdin. Each line is
4631 read on demand and the named file is compiled immediately. (Original patch by
4632 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004634- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004638- Comparisons using one of <, <=, >, >= between a complex instance and a
4639 Fractions instance now raise TypeError instead of returning True/False. This
4640 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4641 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00004650- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004651 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004684- The internals of the subprocess module on POSIX systems have been replaced by
4685 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4686 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004687
Georg Brandl62069d32010-07-31 08:56:11 +00004688- subprocess.Popen now has restore_signals and start_new_session features. The
4689 default of restore_signals=True is a new behavior compared to earlier Python
4690 versions. This means that signals such as SIGPIPE are not ignored by default
4691 in subprocesses launched by Python (Issue #1652).

4778 position when calling `truncate()`. It would previously change the file
4779 position to the given argument, which goes against the tradition of

4784 archive. The new implementation is significantly faster and can be wrapped in
4785 a :class:`io.BufferedReader` object for more speedups. It also solves an
4786 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005184- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005185 compared to other unix systems. In particular, os.getgroups() does not reflect
5186 any changes made using os.setgroups() but basicly always returns the same
5187 information as the id command. os.getgroups() can now return more than 16
5188 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005524- Issue #6551: test_zipimport could import and then destroy some modules of the

5544 threads could return successfully while some Thread objects were still
5545 referenced. This also introduces a new private function:
Antoine Pitrou65c9c642009-10-30 17:25:12 +00005546 :func:`_thread._count()`.

5553
R. David Murray0bc11ae2009-10-18 22:18:17 +00005554- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005555 runtest_inner in regrtest, with warnings if the called test modifies them, and

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005831*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005832
5833Core and Builtins
5834-----------------
5835
Mark Dickinson865e01a2009-05-07 16:37:01 +00005836- Issue #5914: Add new C API function PyOS_string_to_double, and
5837 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5838
Eric Smith741191f2009-05-06 13:08:15 +00005839- Issue #3382: float.__format__, complex.__format__, and %-formatting
5840 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5841 affects nan -> NAN and inf -> INF.
5842
Mark Hammond5a607a32009-05-06 08:04:54 +00005843- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5844 in all operations, including splitdrive, split, etc. splitunc() now issues
5845 a PendingDeprecation warning.
5846
Eric Smith63376222009-05-05 14:04:18 +00005847- Issue #5920: For float.__format__, change the behavior with the
5848 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5849 to be like 'g' but with at least one decimal point and with a
5850 default precision of 12. Previously, the behavior the same but with
5851 a default precision of 6. This more closely matches str(), and
5852 reduces surprises when adding alignment flags to the empty
5853 presentation type. This also affects the new complex.__format__ in
5854 the same way.
5855
Martin v. Löwis011e8422009-05-05 04:43:17 +00005856- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5857
R. David Murrayb18500d2009-05-04 22:59:07 +00005858- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5859 shadowed by classtype's, even if it was None. property now
5860 inserts the __doc__ into the subclass instance __dict__.
5861
Antoine Pitrou244651a2009-05-04 18:56:13 +00005862- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5863 sequences. Patch by Nick Barnes and Victor Stinner.
5864
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005865- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005866
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005867- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5868 received a new method, detach(). detach() disconnects the underlying stream
5869 from the buffer or text IO and returns it.
5870
Mark Dickinson33841c32009-05-01 15:37:04 +00005871- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5872 floats with absolute value over 1e50. Also remove length
5873 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5874 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005875
Eric Smith741191f2009-05-06 13:08:15 +00005876- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005877 format(complex(1, 2./3), '.5') now produces a sensible result.
5878
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005879- Issue #5864: Fix empty format code formatting for floats so that it
5880 never gives more than the requested number of significant digits.
5881
Eric Smith6dc46f52009-04-27 20:39:49 +00005882- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5883 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5884
Eric Smithcc32a112009-04-26 21:35:14 +00005885- Issue #5835: Deprecate PyOS_ascii_formatd.
5886
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005887- Issue #4971: Fix titlecase for characters that are their own
5888 titlecase, but not their own uppercase.
5889
Benjamin Peterson193152c2009-04-25 01:08:45 +00005890- Issue #5283: Setting __class__ in __del__ caused a segfault.
5891
Mark Dickinsonad476da2009-04-23 19:14:16 +00005892- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5893 z involves nans, infs or negative zeros.
5894
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005895- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005896
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005897- Issue #1869 (and many duplicates): make round(x, n) correctly
5898 rounded for a float x, by using the decimal <-> binary conversions
5899 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5900 consistently agrees with format(x, '.2f').
5901
Benjamin Petersonae937c02009-04-18 20:54:08 +00005902- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5903 some builtin types.
5904
Eric Smith0923d1d2009-04-16 20:16:10 +00005905- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5906
Eric Smith35e84722009-04-16 20:21:28 +00005907- Issue #5515: str.format() type 'n' combined with commas and leading
5908 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005909
5910- Implement PEP 378, Format Specifier for Thousands Separator, for
5911 floats.
5912
Mark Dickinson3370cce2009-04-17 22:40:53 +00005913- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005914 1e11, not 1e12. This avoids printing 13 significant digits in
5915 situations where only 12 of them are correct. Example problem
5916 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5917 long time.)
5918
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005919- Issue #1580: On most platforms, use a 'short' float repr: for a
5920 finite float x, repr(x) now outputs a string based on the shortest
5921 sequence of decimal digits that rounds to x. Previous behaviour was
5922 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005923 Another minor difference is that the new repr switches to
5924 exponential notation at 1e16 instead of the previous 1e17; this
5925 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005926
5927 There's a new sys attribute sys.float_repr_style, which takes
5928 the value 'short' to indicate that we're using short float repr,
5929 and 'legacy' if the short float repr isn't available for one
5930 reason or another.
5931
5932 The float repr change involves incorporating David Gay's 'perfect
5933 rounding' code into the Python core (it's in Python/dtoa.c). As a
5934 secondary consequence, all string-to-float and float-to-string
5935 conversions (including all float formatting operations) will be
5936 correctly rounded on these platforms.
5937
Georg Brandl5f90d792010-08-01 22:31:05 +00005938 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005939 this change does not apply.
5940
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005941- Issue #5759: float() didn't call __float__ on str subclasses.
5942
Georg Brandlabc38772009-04-12 15:51:51 +00005943- The string.maketrans() function is deprecated; there is a new static method
5944 maketrans() on the bytes and bytearray classes. This removes confusion about
5945 the types string.maketrans() is supposed to work with, and mirrors the
5946 methods available on the str class.
5947
R. David Murraydc6da8a2009-04-09 22:16:43 +00005948- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5949 its clarity and its speed.
5950
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005951- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005952 to avoid compiler warnings.
5953
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005954- Issue #3739: The unicode-internal encoder now reports the number of characters
5955 consumed like any other encoder (instead of the number of bytes).

6095 byte, and the 'C' code only accepts a unicode character.
6096
Georg Brandl406b3d82009-04-11 21:24:37 +00006097- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
6098 when hitting the recursion limit under certain circumstances.
6099
Brett Cannon0759dd62009-04-01 18:13:07 +00006100- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
6101
Georg Brandlab6f2f62009-03-31 04:16:10 +00006102- Fix a segfault when running test_exceptions with coverage, caused by
6103 insufficient checks in accessors of Exception.__context__.
6104
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006105- Issue #5604: non-ASCII characters in module name passed to
6106 imp.find_module() were converted to UTF-8 while the path is
6107 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006111- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6112 the end sys.path, for compatibility with the system install of Python.
6113
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006114- Issue #4688: Add a heuristic so that tuples and dicts containing only
6115 untrackable objects are not tracked by the garbage collector. This can
6116 reduce the size of collections and therefore the garbage collection overhead
6117 on long-running programs, depending on their particular use of datatypes.
6118
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006119- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
6120 improve its performance. Long divisions and remainder operations
6121 are now between 50% and 150% faster.
6122
Mark Dickinsonbd792642009-03-18 20:06:12 +00006123- Issue #4258: Make it possible to use base 2**30 instead of base
6124 2**15 for the internal representation of integers, for performance
6125 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6126 --enable-big-digits option to configure, which overrides the
6127 default. Add sys.int_info structseq to provide information about
6128 the internal format.
6129
Mark Dickinson081dfee2009-03-18 14:47:41 +00006130- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6131 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6132 and sizeof(Py_UNICODE) == 2.
6133
Eric Smith8ec90442009-03-14 12:29:34 +00006134- Issue #5237: Allow auto-numbered fields in str.format(). For

6136
Antoine Pitrou652e7072009-03-13 19:25:20 +00006137- Issue #5392: when a very low recursion limit was set, the interpreter would
6138 abort with a fatal error after the recursion limit was hit twice.
6139
Matthias Klose042f1332009-04-04 14:32:42 +00006140- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Lars Gustäbel42e00912009-03-22 20:34:29 +00006187- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6188 forever on incomplete input. That caused tarfile.open() to hang when used
6189 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

6229 used when using str.format() with str, int, and float arguments.
6230
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006231- Issue #5249: time.strftime returned malformed string when format string
6232 contained non ascii character on windows.
6233
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006234- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6235 source has already been decoded into str.
6236
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006237- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6238 rotating the object pointer by 4 bits to the right.
6239
Mark Dickinson87ec0852009-02-09 17:15:59 +00006240- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6241 it now forces its argument to double before testing for infinity.
6242
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006243- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6244 returns a non-number type.
6245
Benjamin Peterson87618552009-02-08 15:00:52 +00006246- Issue #5182: Removed memoryview.__str__.
6247
Mark Dickinsonc008a172009-02-01 13:59:22 +00006248- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6249 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006250 the type definition cmpfunc. The tp_compare slot has been renamed
6251 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006252
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006253- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006254 were suppressing all exceptions. These include list() and bytearray().
6255
Mark Dickinson1124e712009-01-28 21:25:58 +00006256- Issue #4707: round(x, n) now returns an integer if x is an integer.
6257 Previously it returned a float.
6258
Antoine Pitroub52ec782009-01-25 16:34:23 +00006259- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6260 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6261 evaluation loop is compiled with a new dispatch mechanism which gives
6262 speedups of up to 20%, depending on the system, on various benchmarks.
6263
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006264- Issue #4874: Most builtin decoders now reject unicode input.

6272 optional module state data.
6273
Mark Dickinson8055afd2009-01-17 10:04:45 +00006274- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006275 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006276
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006277- Issue #4935: The overflow checking code in the expandtabs() method common
6278 to str, bytes and bytearray could be optimized away by the compiler, letting
6279 the interpreter segfault instead of raising an error.
6280
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006281- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6282 __next__ method.
6283
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006284- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6285 function no longer attempt to call the __long__ slot to convert an object
6286 to an integer. Only the __int__ and __trunc__ slots are examined.
6287

6291
Antoine Pitrouab868312009-01-10 15:40:25 +00006292- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6293 common cases are optimized thanks to a dedicated fast path and a moderate
6294 amount of loop unrolling.
6295
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006296- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6297 collecting the oldest generation) so that allocating lots of objects without
6298 destroying them does not show quadratic performance. Based on a proposal by
6299 Martin von Löwis at
6300 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6301
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006302- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006303 having been closed (for instance, a read() call could return some
6304 previously buffered data). Patch by Dmitry Vasiliev.
6305
Antoine Pitrou05608432009-01-09 18:53:14 +00006306- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6307 flag to work properly. Furthermore, when specifying -u, the text stdout
6308 and stderr streams have line-by-line buffering enabled (the default being
6309 to buffer arbitrary chunks of data).
6310
Raymond Hettinger35631532009-01-09 03:58:09 +00006311- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6312 instead of ints (reducing its size from 4 to 8 times thereby reducing
6313 Python's overall memory).
6314
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006315- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6316 an existing .py counterpart, override the co_filename attributes of all
6317 code objects if the original filename is obsolete (which can happen if the
6318 file has been renamed, moved, or if it is accessed through different paths).
6319 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6320
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006321- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6322 one byte. Also fixes the meaning of len() so that it returns the number of
6323 items, rather than the size in bytes.
6324
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006325- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6326
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006327- Issue #4747: When the terminal does not use utf-8, executing a script with
6328 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6329
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006330- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6331 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006332
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006333- Issue #3680: Reference cycles created through a dict, set or deque iterator
6334 did not get collected.
6335
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006336- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6337 where the tp_hash and tp_dict slots are both NULL.
6338
Georg Brandlccc47b62008-12-28 11:44:14 +00006339- Issue #4759: None is now allowed as the first argument of
6340 bytearray.translate(). It was always allowed for bytes.translate().
6341
Skip Montanaro80072cb2008-12-23 03:51:14 +00006342- Added test case to ensure attempts to read from a file opened for writing
6343 fail.
6344
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006345- Issue #3106: Speedup some comparisons (str/str and int/int).

6348 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6349
Antoine Pitrou621601a2008-12-17 23:18:19 +00006350- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6351 print elapsed times, not only when some objects are uncollectable /
6352 unreachable. Original patch by Neil Schemenauer.
6353
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006354- Issue #3439: Add a bit_length method to int.
6355
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006356- Issue #2173: When getting device encoding, check that return value of
6357 nl_langinfo is not the empty string. This was causing silent build
6358 failures on OS X.
6359
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006360- Issue #4597: Fixed several opcodes that weren't always propagating
6361 exceptions.
6362
6363- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006364 context manager returns a value that cannot be converted to a bool.
6365
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006366- Issue #4445: Replace "sizeof(PyBytesObject)" with
6367 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6368 bytes instances. On a typical machine this saves 3 bytes of memory
6369 (on average) per allocation of a bytes instance.
6370
Christian Heimesa872de52008-12-05 08:26:55 +00006371- Issue #4533: File read operation was dreadfully slow due to a slowly
6372 growing read buffer. Fixed by using the same growth rate algorithm as
6373 Python 2.x.
6374
Antoine Pitrou5504e892008-12-06 21:27:53 +00006375- Issue #4509: Various issues surrounding resize of bytearray objects to

6712
Antoine Pitrou08838b62009-01-21 00:55:13 +00006713- Issue #5008: When a file is opened in append mode with the new IO library,
6714 do an explicit seek to the end of file (so that e.g. tell() returns the
6715 file size rather than 0). This is consistent with the behaviour of the
6716 traditional 2.x file object.

6746 appropriately when it is being used via socket.makefile() objects
6747 rather than delaying the close by waiting for garbage collection to do it.
6748
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006749- Issue #1696199: Add collections.Counter() for rapid and convenient

Antoine Pitrou88909542009-06-29 13:54:42 +00006995- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6996 regression tests in parallel, shortening the total runtime.
6997
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006998- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6999 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
7000 the same behaviour as test_ttkguionly (and now also test_tk) which is to
7001 skip the tests if DISPLAY is defined but can't be used.
7002
R. David Murraya21e4ca2009-03-31 23:16:50 +00007003- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00007004 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00007005 from test support, which does the conversion.
7006
Guilherme Polo9de29af2009-01-28 20:40:48 +00007007- Issue #5083: New 'gui' resource for regrtest.
