Ned Deily657b2de2011-06-28 19:51:30 -0700593- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
594 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
595 interpreter process. This could cause failures in non-Distutils subprocesses
596 and was unreliable since tests or user programs could modify the interpreter
597 environment after Distutils set it. Instead, have Distutils set the the
598 deployment target only in the environment of each build subprocess. It is
599 still possible to globally override the default by setting
600 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
601 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700602 was built. Also, implement the same handling in packaging.

1691 keyword-only argument. The preceding positional argument was deprecated,
1692 so it made no sense to add filter as a positional argument.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00001707 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1708 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
1709 for all file entries in the ZIP file.

1719- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1720 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1721 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00001722
1723- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001724 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001725 that for incoming headers which makes this behaviour now consistent in
1726 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001822- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001823 continuation line in the formatted value has no leading white space and looks
1824 like a header. Since Generator uses Header to format all headers, this check
1825 is made for all headers in any serialized message at serialization time. This
1826 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001827
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001828- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +02001835 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001836 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001837
Éric Araujof0ab5d62011-05-29 03:43:59 +02001838- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001839 rfc2047-encoding header values with embedded newlines, leaving them without
1840 folding whitespace. It now uses the continuation_ws, as it does for
1841 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001843- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1844 time.asctime(), time.ctime() and time.strftime() functions will now format
1845 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1846 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1847 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1848 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001849
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001850- Issue #7858: Raise an error properly when os.utime() fails under Windows

2865
Georg Brandl27a28582010-10-10 09:49:21 +00002866- All SyntaxErrors now have a column offset and therefore a caret when the error

2876 with a non-empty format string. This is an effort to future-proof user
2877 code. If a derived class does not currently implement __format__ but later
2878 adds its own __format__, it would most likely break user code that had
2879 supplied a format string. This will be changed to a DeprecationWaring in
2880 Python 3.3 and it will be an error in Python 3.4.

2884 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

2887 functions from the libc caused the methods .upper() and lower() to become
2888 locale aware and created subtly wrong results.
2889
Georg Brandl27a28582010-10-10 09:49:21 +00002890- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002893- Issue #4617: Previously it was illegal to delete a name from the local
2894 namespace if it occurs as a free variable in a nested block. This limitation
2895 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2896
Georg Brandl27a28582010-10-10 09:49:21 +00002897- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2898 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2899 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2900 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002935- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002936 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002937 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002938 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002963 retry the select() loop instead of bailing out. This is because select() can

Georg Brandl27a28582010-10-10 09:49:21 +00003046 it possible for the user to create self-referencing ordered dictionaries which
3047 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003048 approach of using weakref proxies so that reference cycles never get created
3049 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003092 * Update the seed() method to use all of the bits in a string instead of just
3093 the hash value. This makes better use of the seed value and assures the
3094 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003096 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3097 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3098 which has a slight bias whenever n is not a power of two. Issue #9025.

3121 guaranteed to exist in all Python implementations and the names of hash
3122 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003214- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3215 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00003227- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3228 now removed, since their effect was inexistent in 3.x (the default encoding is
3229 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003230
Antoine Pitroub0fa8312010-09-01 15:10:12 +00003231- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

Georg Brandl649971e2010-09-05 17:06:50 +00003234- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3235 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00003236

3251 return characters from the full Unicode range, even on narrow unicode builds
3252 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3253 in Python is that unicodedata.numeric() now returns the correct value for
3254 large code points, and repr() may consider more characters as printable.
3255
Victor Stinner6c00c142010-08-17 23:37:11 +00003256- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

3264
Georg Brandl649971e2010-09-05 17:06:50 +00003265- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
3266 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00003267

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003272- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003273 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3274 objects are output as-is.

3278 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003279
Georg Brandl649971e2010-09-05 17:06:50 +00003280- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3281 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003282
Georg Brandl649971e2010-09-05 17:06:50 +00003283- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
3284 array.

3289 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003290
Georg Brandl649971e2010-09-05 17:06:50 +00003291- Issue #9416: Fix some issues with complex formatting where the output with no
3292 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003293
3294 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3295 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3636 the number of bytes specified by the start byte. E.g.:

3638 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3639 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3640 returned a single u'\ufffd'.

Victor Stinner25e8ec42010-06-25 00:02:38 +00003663- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3664 "w*" format instead. Add tests for "w*" format.
3665
Victor Stinner06e49dd2010-06-13 18:21:50 +00003666- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003667 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003668 string formats.
3669
Georg Brandl62069d32010-07-31 08:56:11 +00003670- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003671 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3672 location of the raised exception.
3673
Victor Stinner313a1202010-06-11 23:56:51 +00003674- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3675 filenames and enable os.fsencode().
3676
Benjamin Peterson285a6892010-06-22 19:21:52 +00003677- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3678
Georg Brandl62069d32010-07-31 08:56:11 +00003679- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3680 interpreter with characters outside the Basic Multilingual Plane (higher than
3681 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003682
Georg Brandl62069d32010-07-31 08:56:11 +00003683- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3684 TypeError instead of giving a DeprecationWarning when a float is parsed using
3685 the 'L' code (for long long). (All other integer codes already raise
3686 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003687
Victor Stinner600d3be2010-06-10 12:00:55 +00003688- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3689 enable shortcuts for upper case encoding name. Add also a shortcut for
3690 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3691
Georg Brandl62069d32010-07-31 08:56:11 +00003692- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3693 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003694
3695- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003696 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003697 like bytearray.
3698
Georg Brandl62069d32010-07-31 08:56:11 +00003699- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003700 used anymore and it was never documented.
3701
Georg Brandl62069d32010-07-31 08:56:11 +00003702- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003703
Georg Brandl62069d32010-07-31 08:56:11 +00003704- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3705 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003706
Georg Brandl62069d32010-07-31 08:56:11 +00003707- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3708 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3709 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3710 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003711
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003712- Issue #8748: Fix two issues with comparisons between complex and integer
3713 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003714 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3715 (2) The comparison raised an OverflowError for large integers, leading to
3716 unpredictable exceptions when combining integers and complex objects in sets
3717 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003718
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003719- Issue #8766: Initialize _warnings module before importing the first module.
3720 Fix a crash if an empty directory called "encodings" exists in sys.path.
3721
Victor Stinner9ca9c252010-05-19 16:53:30 +00003722- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003723 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003724 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003725
Georg Brandl62069d32010-07-31 08:56:11 +00003726- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3727 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003728
Victor Stinnerae6265f2010-05-15 16:27:27 +00003729- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3730 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003731 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003732 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003733
Victor Stinner59e62db2010-05-15 13:14:32 +00003734- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003735 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003736
Victor Stinnerb744ba12010-05-15 12:27:16 +00003737- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003738 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003739 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3740
Victor Stinner0964ee12010-04-30 16:48:45 +00003741- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003742 PyUnicode_FromString() to support surrogates in the filename and use the right
3743 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003744
Georg Brandl8569e582010-05-19 20:57:08 +00003745- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3746
Georg Brandl62069d32010-07-31 08:56:11 +00003747- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003748
Benjamin Petersonfb886362010-04-24 18:21:17 +00003749- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3750 arguments.
3751
Victor Stinner14284c22010-04-23 12:02:30 +00003752- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003753 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3754 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003755
Victor Stinner31be90b2010-04-22 19:38:16 +00003756- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00003758
Georg Brandl62069d32010-07-31 08:56:11 +00003759- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3760 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003761
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003762- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003763 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3764 compared to the dynamic memory allocation fallback. Patch by Charles-François
3765 Natali.
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003766
Benjamin Peterson8380dd52010-04-16 22:51:37 +00003767- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
3768 passed to bytes or bytearray.
3769

3773 changed.
3774
Georg Brandl62069d32010-07-31 08:56:11 +00003775- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
3776 64-bit machines. The shift count for either left or right shift is permitted
3777 to be up to sys.maxsize.

Mark Dickinsond59b4162010-03-13 11:34:40 +00003793- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
Georg Brandl62069d32010-07-31 08:56:11 +00003794 PyMemberDefs could produce an internal error; raise TypeError instead.
Mark Dickinsond59b4162010-03-13 11:34:40 +00003795
Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003796- Issue #7845: Rich comparison methods on the complex type now return
3797 NotImplemented rather than raising a TypeError when comparing with an
3798 incompatible type; this allows user-defined classes to implement their own
3799 comparisons with complex.
3800
Victor Stinner52f6dd72010-03-12 14:45:56 +00003801- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
3802 (SIGINT). If an error occurs while importing the site module, the error is

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003846- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003847 where the right hand operand is a set of constants, by turning the set into a
3848 frozenset and pre-building it as a constant. The comparison operation is made
3849 against the constant instead of building a new set each time it is executed (a
3850 similar optimization already existed which turned a list of constants into a
3851 pre-built tuple). Patch and additional tests by Dave Malcolm.

3858 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3859 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3860 parsing certain long numeric strings corresponding to subnormal values, (3) a
3861 memory leak for some values large enough to cause overflow, and (4) a number
3862 of flaws that could lead to incorrectly rounded results.

4022
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004023- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4024 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

4047 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4048 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004049 to match the behaviour of the other integer format codes.

Antoine Pitrou3060c452010-08-13 16:27:38 +00004154 simply clearing the entire cache on overflow to forgetting the least recently
4155 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004156 applications that use a lot of regular expressions and limits the impact of
4157 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004411- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4412 operation raises multiple signals and more than one of those signals is
4413 trapped, the specification determines the order in which the signals should be
4414 handled. In many cases this order wasn't being followed, leading to the wrong
4415 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004454- Issue #8524: When creating an SSL socket, the timeout value of the original
4455 socket wasn't retained (instead, a socket with a positive timeout would be
4456 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004457
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004458- Issue #5103: SSL handshake would ignore the socket timeout and block

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004579- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004580 argument `-` which tells it to read files to compile from stdin. Each line is
4581 read on demand and the named file is compiled immediately. (Original patch by
4582 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004588- Comparisons using one of <, <=, >, >= between a complex instance and a
4589 Fractions instance now raise TypeError instead of returning True/False. This
4590 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4591 <=> complex, and complex <=> complex comparisons.

4635 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4636 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004638- subprocess.Popen now has restore_signals and start_new_session features. The
4639 default of restore_signals=True is a new behavior compared to earlier Python
4640 versions. This means that signals such as SIGPIPE are not ignored by default
4641 in subprocesses launched by Python (Issue #1652).

5052 occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
5053 "wb+" mode) after having buffered a certain amount of data for reading. This
5054 bug was not present in the pure Python implementation.

5060
Georg Brandl62069d32010-07-31 08:56:11 +00005061- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
5062 digits in input, as recommended by the standard. Previously it was restricted
5063 to accepting [0-9].
Mark Dickinson345adc42009-08-02 10:14:23 +00005064
Jack Diederich36596a32009-07-26 22:23:04 +00005065- Issue #6106: telnetlib.Telnet.process_rawq doesn't handle default WILL/WONT

Brett Cannon69194272009-07-20 04:23:48 +00005072- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005073 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5074 PyPycLoader inherit from this class and provide implementations in relation to
5075 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005076
Brett Cannon64ef00f2009-07-20 03:19:18 +00005077- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5078 the documentation said it did even though the code in PyLoader relied on the
5079 abstract method required by ResourceLoader.
5080
Georg Brandl62069d32010-07-31 08:56:11 +00005081- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00005129- Issue #9959: Tweak formula used for computing math.log of an integer,
5130 making it marginally more accurate for exact powers of 2.
5131
Mark Dickinsoncf28b952010-07-29 21:41:59 +00005132- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
5133
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005134- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005135 compared to other unix systems. In particular, os.getgroups() does not reflect
5136 any changes made using os.setgroups() but basicly always returns the same
5137 information as the id command. os.getgroups() can now return more than 16
5138 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005139
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00005140- Issue #6095: Make directory argument to os.listdir optional.

5143 struct.pack('>?')): if conversion to bool raised an exception then that
5144 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00005145
Georg Brandl62069d32010-07-31 08:56:11 +00005146- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
5147 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00005148
Georg Brandl62069d32010-07-31 08:56:11 +00005149- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany

5159
Benjamin Petersonf751bc92010-07-02 13:46:42 +00005160- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
5161 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00005162
Georg Brandl62069d32010-07-31 08:56:11 +00005163- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5164 Prior to this change, timezone adjustment in utctimetuple() could produce
5165 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5166 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005168- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5169 directive. When the ``%z`` directive is present in the format string, an
5170 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5171 ``datetime.timezone`` instance constructed from the parsed offset. If both
5172 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5173 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005174
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005175- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005176 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5177 ``datetime.timezone``, return fixed name and UTC offset from their
5178 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5179 returns ``None``. A class attribute, ``utc`` contains an instance
5180 representing the UTC timezone. Original patch by Rafe Kaplan.

5191 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00005192

Georg Brandl62069d32010-07-31 08:56:11 +00005196- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5197 with an improved 'binary-split' algorithm that uses fewer multiplications and
5198 allows many of the multiplications to be performed using plain C integer
5199 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5200 arguments.

5204
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005205- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5206 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005207 the result is now always correctly rounded, and is equivalent to ``td /
5208 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00005216- Issue #8300: When passing a non-integer argument to struct.pack with any
5217 integer format code, struct.pack first attempts to convert the non-integer
5218 using its __index__ method. If that method is non-existent or raises
5219 TypeError it goes on to try the __int__ method, as described below.
5220

5799 to be like 'g' but with at least one decimal point and with a
5800 default precision of 12. Previously, the behavior the same but with
5801 a default precision of 6. This more closely matches str(), and
5802 reduces surprises when adding alignment flags to the empty
5803 presentation type. This also affects the new complex.__format__ in
5804 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005817- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5818 received a new method, detach(). detach() disconnects the underlying stream
5819 from the buffer or text IO and returns it.
5820
Mark Dickinson33841c32009-05-01 15:37:04 +00005821- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5822 floats with absolute value over 1e50. Also remove length
5823 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5824 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00005826- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005827 format(complex(1, 2./3), '.5') now produces a sensible result.
5828
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005829- Issue #5864: Fix empty format code formatting for floats so that it
5830 never gives more than the requested number of significant digits.
5831
Eric Smith6dc46f52009-04-27 20:39:49 +00005832- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5833 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5834

Martin v. Löwis71efeb72009-04-26 01:02:07 +00005837- Issue #4971: Fix titlecase for characters that are their own
5838 titlecase, but not their own uppercase.
5839
Benjamin Peterson193152c2009-04-25 01:08:45 +00005840- Issue #5283: Setting __class__ in __del__ caused a segfault.
5841
Mark Dickinsonad476da2009-04-23 19:14:16 +00005842- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5843 z involves nans, infs or negative zeros.
5844
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005845- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005846
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005847- Issue #1869 (and many duplicates): make round(x, n) correctly
5848 rounded for a float x, by using the decimal <-> binary conversions
5849 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5850 consistently agrees with format(x, '.2f').
5851
Benjamin Petersonae937c02009-04-18 20:54:08 +00005852- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5853 some builtin types.
5854
Eric Smith0923d1d2009-04-16 20:16:10 +00005855- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5856
Eric Smith35e84722009-04-16 20:21:28 +00005857- Issue #5515: str.format() type 'n' combined with commas and leading
5858 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005859
5860- Implement PEP 378, Format Specifier for Thousands Separator, for
5861 floats.
5862
Mark Dickinson3370cce2009-04-17 22:40:53 +00005863- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005864 1e11, not 1e12. This avoids printing 13 significant digits in
5865 situations where only 12 of them are correct. Example problem
5866 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5867 long time.)
5868
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005869- Issue #1580: On most platforms, use a 'short' float repr: for a
5870 finite float x, repr(x) now outputs a string based on the shortest
5871 sequence of decimal digits that rounds to x. Previous behaviour was
5872 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005873 Another minor difference is that the new repr switches to
5874 exponential notation at 1e16 instead of the previous 1e17; this
5875 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005876
5877 There's a new sys attribute sys.float_repr_style, which takes
5878 the value 'short' to indicate that we're using short float repr,
5879 and 'legacy' if the short float repr isn't available for one
5880 reason or another.
5881
5882 The float repr change involves incorporating David Gay's 'perfect
5883 rounding' code into the Python core (it's in Python/dtoa.c). As a
5884 secondary consequence, all string-to-float and float-to-string
5885 conversions (including all float formatting operations) will be
5886 correctly rounded on these platforms.
5887
Georg Brandl5f90d792010-08-01 22:31:05 +00005888 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005889 this change does not apply.
5890
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005891- Issue #5759: float() didn't call __float__ on str subclasses.
5892
Georg Brandlabc38772009-04-12 15:51:51 +00005893- The string.maketrans() function is deprecated; there is a new static method
5894 maketrans() on the bytes and bytearray classes. This removes confusion about
5895 the types string.maketrans() is supposed to work with, and mirrors the
5896 methods available on the str class.
5897
R. David Murraydc6da8a2009-04-09 22:16:43 +00005898- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5899 its clarity and its speed.
5900
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005901- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005902 to avoid compiler warnings.
5903
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005904- Issue #3739: The unicode-internal encoder now reports the number of characters
5905 consumed like any other encoder (instead of the number of bytes).

6063
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006064- Issue #4688: Add a heuristic so that tuples and dicts containing only
6065 untrackable objects are not tracked by the garbage collector. This can
6066 reduce the size of collections and therefore the garbage collection overhead
6067 on long-running programs, depending on their particular use of datatypes.

6074 2**15 for the internal representation of integers, for performance
6075 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6076 --enable-big-digits option to configure, which overrides the
6077 default. Add sys.int_info structseq to provide information about
6078 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006190- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6191 it now forces its argument to double before testing for infinity.
6192
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006193- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6194 returns a non-number type.
6195
Benjamin Peterson87618552009-02-08 15:00:52 +00006196- Issue #5182: Removed memoryview.__str__.
6197
Mark Dickinsonc008a172009-02-01 13:59:22 +00006198- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006202
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006203- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006204 were suppressing all exceptions. These include list() and bytearray().
6205
Mark Dickinson1124e712009-01-28 21:25:58 +00006206- Issue #4707: round(x, n) now returns an integer if x is an integer.
6207 Previously it returned a float.
6208
Antoine Pitroub52ec782009-01-25 16:34:23 +00006209- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6210 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6211 evaluation loop is compiled with a new dispatch mechanism which gives
6212 speedups of up to 20%, depending on the system, on various benchmarks.
6213
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006214- Issue #4874: Most builtin decoders now reject unicode input.

6222 optional module state data.
6223
Mark Dickinson8055afd2009-01-17 10:04:45 +00006224- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006225 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006226
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006227- Issue #4935: The overflow checking code in the expandtabs() method common
6228 to str, bytes and bytearray could be optimized away by the compiler, letting
6229 the interpreter segfault instead of raising an error.
6230
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006231- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6232 __next__ method.
6233
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006234- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6235 function no longer attempt to call the __long__ slot to convert an object
6236 to an integer. Only the __int__ and __trunc__ slots are examined.
6237
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006238- Issue #4893: Use NT threading on CE.
6239

6241
Antoine Pitrouab868312009-01-10 15:40:25 +00006242- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6243 common cases are optimized thanks to a dedicated fast path and a moderate
6244 amount of loop unrolling.
6245
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006246- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6247 collecting the oldest generation) so that allocating lots of objects without
6248 destroying them does not show quadratic performance. Based on a proposal by
6249 Martin von Löwis at
6250 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6251
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006252- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006253 having been closed (for instance, a read() call could return some
6254 previously buffered data). Patch by Dmitry Vasiliev.
6255
Antoine Pitrou05608432009-01-09 18:53:14 +00006256- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6257 flag to work properly. Furthermore, when specifying -u, the text stdout
6258 and stderr streams have line-by-line buffering enabled (the default being
6259 to buffer arbitrary chunks of data).
6260
Raymond Hettinger35631532009-01-09 03:58:09 +00006261- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6262 instead of ints (reducing its size from 4 to 8 times thereby reducing
6263 Python's overall memory).
6264
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006265- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6266 an existing .py counterpart, override the co_filename attributes of all
6267 code objects if the original filename is obsolete (which can happen if the
6268 file has been renamed, moved, or if it is accessed through different paths).
6269 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6270
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006271- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6272 one byte. Also fixes the meaning of len() so that it returns the number of
6273 items, rather than the size in bytes.
6274
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006275- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6276
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006277- Issue #4747: When the terminal does not use utf-8, executing a script with
6278 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6279
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006280- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6281 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006282
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006283- Issue #3680: Reference cycles created through a dict, set or deque iterator
6284 did not get collected.
6285
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006286- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6287 where the tp_hash and tp_dict slots are both NULL.
6288
Georg Brandlccc47b62008-12-28 11:44:14 +00006289- Issue #4759: None is now allowed as the first argument of
6290 bytearray.translate(). It was always allowed for bytes.translate().
6291
Skip Montanaro80072cb2008-12-23 03:51:14 +00006292- Added test case to ensure attempts to read from a file opened for writing
6293 fail.
6294
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006295- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00006297- Issue #2183: Simplify and optimize bytecode for list, dict and set
6298 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6299
Antoine Pitrou621601a2008-12-17 23:18:19 +00006300- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6301 print elapsed times, not only when some objects are uncollectable /
6302 unreachable. Original patch by Neil Schemenauer.
6303
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006304- Issue #3439: Add a bit_length method to int.
6305
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006306- Issue #2173: When getting device encoding, check that return value of
6307 nl_langinfo is not the empty string. This was causing silent build
6308 failures on OS X.
6309
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006310- Issue #4597: Fixed several opcodes that weren't always propagating
6311 exceptions.
6312
6313- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006314 context manager returns a value that cannot be converted to a bool.
6315
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006316- Issue #4445: Replace "sizeof(PyBytesObject)" with
6317 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6318 bytes instances. On a typical machine this saves 3 bytes of memory
6319 (on average) per allocation of a bytes instance.
6320
Christian Heimesa872de52008-12-05 08:26:55 +00006321- Issue #4533: File read operation was dreadfully slow due to a slowly
6322 growing read buffer. Fixed by using the same growth rate algorithm as
6323 Python 2.x.
6324
Antoine Pitrou5504e892008-12-06 21:27:53 +00006325- Issue #4509: Various issues surrounding resize of bytearray objects to
6326 which there are buffer exports (e.g. memoryview instances).
6327
Georg Brandlf9734072008-12-07 15:30:06 +00006328- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6329 method on file objects with closefd=False. The file descriptor is still
6330 kept open but the file object behaves like a closed file. The ``FileIO``
6331 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006332
Antoine Pitroubc420402008-12-07 20:14:49 +00006333- Issue #4569: Interpreter crash when mutating a memoryview with an item size

6339
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006340- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6341 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6342 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6343 of using the replace error handler in PyUnicode_DecodeUTF8().
