Ned Deily657b2de2011-06-28 19:51:30 -0700602- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
603 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
604 interpreter process. This could cause failures in non-Distutils subprocesses
605 and was unreliable since tests or user programs could modify the interpreter
606 environment after Distutils set it. Instead, have Distutils set the the
607 deployment target only in the environment of each build subprocess. It is
608 still possible to globally override the default by setting
609 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
610 greater or equal to the default value, the value with which the interpreter

Steven Bethardb0270112011-01-24 21:02:50 +00001736
1737- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001738 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001836- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001837 continuation line in the formatted value has no leading white space and looks
1838 like a header. Since Generator uses Header to format all headers, this check
1839 is made for all headers in any serialized message at serialization time. This
1840 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001841
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001842- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +02001849 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001850 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001851
Éric Araujof0ab5d62011-05-29 03:43:59 +02001852- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001853 rfc2047-encoding header values with embedded newlines, leaving them without
1854 folding whitespace. It now uses the continuation_ws, as it does for
1855 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001857- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1858 time.asctime(), time.ctime() and time.strftime() functions will now format
1859 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1860 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1861 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1862 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Antoine Pitroucf9f9802010-11-10 13:55:25 +00002470- Issue #10372: Import the warnings module only after the IO library is
2471 initialized, so as to avoid bootstrap issues with the '-W' option.
2472
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002473- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
2474 undocumented value PyBUF_SHADOW, and strangely-looking code in
Antoine Pitrouaeb6cee2010-11-04 20:30:33 +00002475 PyMemoryView_GetContiguous.
2476
Georg Brandl54445ad2010-11-20 10:24:34 +00002477- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
Eric Smith27bbca62010-11-04 17:06:58 +00002478
Benjamin Petersonbbb04122010-10-30 23:16:28 +00002479- If FileIO.__init__ fails, close the file descriptor.
2480
Raymond Hettingerdd421542010-10-30 08:10:29 +00002481- Issue #10221: dict.pop(k) now has a key error message that includes the
2482 missing key (same message d[k] returns for missing keys).
2483
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002484- Issue #5437: A preallocated MemoryError instance should not keep traceback
Antoine Pitrou07e20ef2010-10-28 22:56:58 +00002485 data (including local variables caught in the stack trace) alive infinitely.
2486

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002493- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2494 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002495 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002496 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002497 encoding and to encode command line arguments on this OS.
2498

2500 filenames encoded to the filesystem encoding with the surrogateescape error
Victor Stinner4c7c8c32010-10-16 13:14:10 +00002501 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
2502
Benjamin Peterson230b2062010-10-16 03:45:45 +00002503- Issue #9997: Don't let the name "top" have special significance in scope
2504 resolution.
2505
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002506- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
2507 the default 512 when compiling on AIX.
R. David Murraye16cda92010-10-15 23:12:57 +00002508
Victor Stinnerf3170cc2010-10-15 12:04:23 +00002509- Use locale encoding instead of UTF-8 to encode and decode filenames if

Victor Stinner22a351a2010-10-14 12:04:34 +00002513 descriptor.
2514
Georg Brandl66c221e2010-10-14 07:04:07 +00002515- Issue #9418: Moved private string methods ``_formatter_parser`` and

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002540- Issue #10386: Add __all__ to token module; this simplifies importing in

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002549 unexpectedly if the return value of a task could not be pickled. Only the
2550 ``repr`` of such errors are now sent back, wrapped in an

2552
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002553- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002610 incorrectly validated some non-compliant applications as WSGI compliant; if
2611 your app validates with Python <3.2b1+, but not on this version, it is likely

2890 with a non-empty format string. This is an effort to future-proof user
2891 code. If a derived class does not currently implement __format__ but later
2892 adds its own __format__, it would most likely break user code that had
2893 supplied a format string. This will be changed to a DeprecationWaring in
2894 Python 3.3 and it will be an error in Python 3.4.

2898 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002907- Issue #4617: Previously it was illegal to delete a name from the local
2908 namespace if it occurs as a free variable in a nested block. This limitation
2909 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2910
Georg Brandl27a28582010-10-10 09:49:21 +00002911- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2912 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2913 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2914 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002949- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002950 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002951 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002952 replacement for old handle_accept() and avoids the user to call accept()
2953 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002977 retry the select() loop instead of bailing out. This is because select() can
2978 incorrectly report a socket as ready for reading (for example, if it received
2979 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003059- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003060 it possible for the user to create self-referencing ordered dictionaries which
3061 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003062 approach of using weakref proxies so that reference cycles never get created
3063 in the first place.
3064
Victor Stinnercb043522010-09-10 23:49:04 +00003065- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Victor Stinnercb043522010-09-10 23:49:04 +00003068
Georg Brandl27a28582010-10-10 09:49:21 +00003069- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3070 environment variable to set the filesystem encoding at Python startup.
3071 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3072 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003073
Georg Brandl27a28582010-10-10 09:49:21 +00003074- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00003078- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00003081- Logging: Added QueueHandler class to facilitate logging usage with
3082 multiprocessing.
3083
Georg Brandl27a28582010-10-10 09:49:21 +00003084- Issue #9707: Rewritten reference implementation of threading.local which is
3085 friendlier towards reference cycles. This change is not normally visible
3086 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003087
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003088- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3089 still return the id of the parent process after it has exited. This process
3090 id may even have been reused by another unrelated process.
3091
Georg Brandl27a28582010-10-10 09:49:21 +00003092- Issue #9792: In case of connection failure, socket.create_connection() would
3093 swallow the exception and raise a new one, making it impossible to fetch the
3094 original errno, or to filter timeout errors. Now the original error is
3095 re-raised.

3098 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3099 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003101- Updates to the random module:
3102
Georg Brandl27a28582010-10-10 09:49:21 +00003103 * Document which parts of the module are guaranteed to stay the same across
3104 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003106 * Update the seed() method to use all of the bits in a string instead of just
3107 the hash value. This makes better use of the seed value and assures the
3108 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003109
Georg Brandl27a28582010-10-10 09:49:21 +00003110 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3111 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3112 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003113
3114 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003133- hashlib has two new constant attributes: algorithms_guaranteed and

3135 guaranteed to exist in all Python implementations and the names of hash
3136 algorithms available in the current process.

3265 return characters from the full Unicode range, even on narrow unicode builds
3266 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3267 in Python is that unicodedata.numeric() now returns the correct value for
3268 large code points, and repr() may consider more characters as printable.
3269
Victor Stinner6c00c142010-08-17 23:37:11 +00003270- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003286- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003287 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3288 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003294- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3295 use PyUnicode_FromFormatV() to format the warning message.

3303 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003304
Georg Brandl649971e2010-09-05 17:06:50 +00003305- Issue #9416: Fix some issues with complex formatting where the output with no
3306 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003307
3308 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3309 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00003668- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3669 dealing with unary minus applied to a constant. The removed code was mutating
3670 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003672- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003673 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003674 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003675 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003676
Victor Stinner25e8ec42010-06-25 00:02:38 +00003677- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3678 "w*" format instead. Add tests for "w*" format.
3679
Victor Stinner06e49dd2010-06-13 18:21:50 +00003680- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003681 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003682 string formats.
3683
Georg Brandl62069d32010-07-31 08:56:11 +00003684- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003685 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3686 location of the raised exception.
3687
Victor Stinner313a1202010-06-11 23:56:51 +00003688- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3689 filenames and enable os.fsencode().
3690
Benjamin Peterson285a6892010-06-22 19:21:52 +00003691- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3692
Georg Brandl62069d32010-07-31 08:56:11 +00003693- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3694 interpreter with characters outside the Basic Multilingual Plane (higher than
3695 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003696
Georg Brandl62069d32010-07-31 08:56:11 +00003697- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3698 TypeError instead of giving a DeprecationWarning when a float is parsed using
3699 the 'L' code (for long long). (All other integer codes already raise
3700 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003701
Victor Stinner600d3be2010-06-10 12:00:55 +00003702- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3703 enable shortcuts for upper case encoding name. Add also a shortcut for
3704 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3705
Georg Brandl62069d32010-07-31 08:56:11 +00003706- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3707 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003708
3709- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003710 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003711 like bytearray.
3712
Georg Brandl62069d32010-07-31 08:56:11 +00003713- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003714 used anymore and it was never documented.
3715
Georg Brandl62069d32010-07-31 08:56:11 +00003716- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003717
Georg Brandl62069d32010-07-31 08:56:11 +00003718- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3719 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003720
Georg Brandl62069d32010-07-31 08:56:11 +00003721- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3722 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3723 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3724 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003725
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003726- Issue #8748: Fix two issues with comparisons between complex and integer
3727 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003728 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3729 (2) The comparison raised an OverflowError for large integers, leading to
3730 unpredictable exceptions when combining integers and complex objects in sets
3731 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003732
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003733- Issue #8766: Initialize _warnings module before importing the first module.
3734 Fix a crash if an empty directory called "encodings" exists in sys.path.
3735
Victor Stinner9ca9c252010-05-19 16:53:30 +00003736- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003737 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003738 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003739
Georg Brandl62069d32010-07-31 08:56:11 +00003740- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3741 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003742
Victor Stinnerae6265f2010-05-15 16:27:27 +00003743- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3744 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003745 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003746 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003747
Victor Stinner59e62db2010-05-15 13:14:32 +00003748- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003749 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003750
Victor Stinnerb744ba12010-05-15 12:27:16 +00003751- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003752 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003753 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3754
Victor Stinner0964ee12010-04-30 16:48:45 +00003755- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003756 PyUnicode_FromString() to support surrogates in the filename and use the right
3757 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003758
Georg Brandl8569e582010-05-19 20:57:08 +00003759- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3760
Georg Brandl62069d32010-07-31 08:56:11 +00003761- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.

Benjamin Petersonfb886362010-04-24 18:21:17 +00003763- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3764 arguments.
3765
Victor Stinner14284c22010-04-23 12:02:30 +00003766- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003767 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00003773- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3774 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003775
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003776- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003777 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3778 compared to the dynamic memory allocation fallback. Patch by Charles-François
3779 Natali.

3788
Georg Brandl62069d32010-07-31 08:56:11 +00003789- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
3790 64-bit machines. The shift count for either left or right shift is permitted
3791 to be up to sys.maxsize.

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003810- Issue #7845: Rich comparison methods on the complex type now return
3811 NotImplemented rather than raising a TypeError when comparing with an
3812 incompatible type; this allows user-defined classes to implement their own
3813 comparisons with complex.
3814

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003860- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003861 where the right hand operand is a set of constants, by turning the set into a
3862 frozenset and pre-building it as a constant. The comparison operation is made
3863 against the constant instead of building a new set each time it is executed (a
3864 similar optimization already existed which turned a list of constants into a
3865 pre-built tuple). Patch and additional tests by Dave Malcolm.

3872 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3873 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3874 parsing certain long numeric strings corresponding to subnormal values, (3) a
3875 memory leak for some values large enough to cause overflow, and (4) a number
3876 of flaws that could lead to incorrectly rounded results.

4171 the performance hit anytime the cache is exceeded.

4572 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004573
4574 >>> Decimal(1.1)
4575 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004580- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4581 InvalidOperation instead of returning False. (Comparisons involving a quiet
4582 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4583 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004585- Issue #2531: Comparison operations between floats and Decimal instances now
4586 return a result based on the numeric values of the operands; previously they
4587 returned an arbitrary result based on the relative ordering of id(float) and
4588 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4589 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004593- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004594 argument `-` which tells it to read files to compile from stdin. Each line is
4595 read on demand and the named file is compiled immediately. (Original patch by
4596 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004602- Comparisons using one of <, <=, >, >= between a complex instance and a
4603 Fractions instance now raise TypeError instead of returning True/False. This
4604 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4605 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004648- The internals of the subprocess module on POSIX systems have been replaced by
4649 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4650 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004652- subprocess.Popen now has restore_signals and start_new_session features. The
4653 default of restore_signals=True is a new behavior compared to earlier Python
4654 versions. This means that signals such as SIGPIPE are not ignored by default
4655 in subprocesses launched by Python (Issue #1652).

4742 position when calling `truncate()`. It would previously change the file
4743 position to the given argument, which goes against the tradition of

4748 archive. The new implementation is significantly faster and can be wrapped in
4749 a :class:`io.BufferedReader` object for more speedups. It also solves an
4750 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00005086- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005087 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5088 PyPycLoader inherit from this class and provide implementations in relation to
5089 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005148- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005149 compared to other unix systems. In particular, os.getgroups() does not reflect
5150 any changes made using os.setgroups() but basicly always returns the same
5151 information as the id command. os.getgroups() can now return more than 16
5152 groups on MacOSX.

5178 Prior to this change, timezone adjustment in utctimetuple() could produce
5179 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5183 directive. When the ``%z`` directive is present in the format string, an
5184 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5185 ``datetime.timezone`` instance constructed from the parsed offset. If both
5186 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5187 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005190 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5191 ``datetime.timezone``, return fixed name and UTC offset from their
5192 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5193 returns ``None``. A class attribute, ``utc`` contains an instance
5194 representing the UTC timezone. Original patch by Rafe Kaplan.

5220 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005221 the result is now always correctly rounded, and is equivalent to ``td /

Mark Hammond5a607a32009-05-06 08:04:54 +00005807- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5808 in all operations, including splitdrive, split, etc. splitunc() now issues
5809 a PendingDeprecation warning.
5810
Eric Smith63376222009-05-05 14:04:18 +00005811- Issue #5920: For float.__format__, change the behavior with the
5812 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5813 to be like 'g' but with at least one decimal point and with a
5814 default precision of 12. Previously, the behavior the same but with
5815 a default precision of 6. This more closely matches str(), and
5816 reduces surprises when adding alignment flags to the empty
5817 presentation type. This also affects the new complex.__format__ in
5818 the same way.
5819
Martin v. Löwis011e8422009-05-05 04:43:17 +00005820- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5821
R. David Murrayb18500d2009-05-04 22:59:07 +00005822- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5823 shadowed by classtype's, even if it was None. property now
5824 inserts the __doc__ into the subclass instance __dict__.
5825
Antoine Pitrou244651a2009-05-04 18:56:13 +00005826- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Martin v. Löwisdb12d452009-05-02 18:52:14 +00005830
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005831- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5832 received a new method, detach(). detach() disconnects the underlying stream
5833 from the buffer or text IO and returns it.
5834
Mark Dickinson33841c32009-05-01 15:37:04 +00005835- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5836 floats with absolute value over 1e50. Also remove length
5837 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5838 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005839
Eric Smith741191f2009-05-06 13:08:15 +00005840- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005841 format(complex(1, 2./3), '.5') now produces a sensible result.
5842
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005843- Issue #5864: Fix empty format code formatting for floats so that it
5844 never gives more than the requested number of significant digits.
5845
Eric Smith6dc46f52009-04-27 20:39:49 +00005846- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5853
Benjamin Peterson193152c2009-04-25 01:08:45 +00005854- Issue #5283: Setting __class__ in __del__ caused a segfault.
5855
Mark Dickinsonad476da2009-04-23 19:14:16 +00005856- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5857 z involves nans, infs or negative zeros.
5858
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005859- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005860
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005861- Issue #1869 (and many duplicates): make round(x, n) correctly
5862 rounded for a float x, by using the decimal <-> binary conversions
5863 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5864 consistently agrees with format(x, '.2f').
5865
Benjamin Petersonae937c02009-04-18 20:54:08 +00005866- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5867 some builtin types.
5868
Eric Smith0923d1d2009-04-16 20:16:10 +00005869- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5870
Eric Smith35e84722009-04-16 20:21:28 +00005871- Issue #5515: str.format() type 'n' combined with commas and leading
5872 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005873
5874- Implement PEP 378, Format Specifier for Thousands Separator, for
5875 floats.
5876
Mark Dickinson3370cce2009-04-17 22:40:53 +00005877- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005878 1e11, not 1e12. This avoids printing 13 significant digits in
5879 situations where only 12 of them are correct. Example problem
5880 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5881 long time.)
5882
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005883- Issue #1580: On most platforms, use a 'short' float repr: for a
5884 finite float x, repr(x) now outputs a string based on the shortest
5885 sequence of decimal digits that rounds to x. Previous behaviour was
5886 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005887 Another minor difference is that the new repr switches to
5888 exponential notation at 1e16 instead of the previous 1e17; this
5889 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005890
5891 There's a new sys attribute sys.float_repr_style, which takes
5892 the value 'short' to indicate that we're using short float repr,
5893 and 'legacy' if the short float repr isn't available for one
5894 reason or another.
5895
5896 The float repr change involves incorporating David Gay's 'perfect
5897 rounding' code into the Python core (it's in Python/dtoa.c). As a
5898 secondary consequence, all string-to-float and float-to-string
5899 conversions (including all float formatting operations) will be
5900 correctly rounded on these platforms.
5901
Georg Brandl5f90d792010-08-01 22:31:05 +00005902 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005903 this change does not apply.
5904
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005905- Issue #5759: float() didn't call __float__ on str subclasses.
5906
Georg Brandlabc38772009-04-12 15:51:51 +00005907- The string.maketrans() function is deprecated; there is a new static method
5908 maketrans() on the bytes and bytearray classes. This removes confusion about
5909 the types string.maketrans() is supposed to work with, and mirrors the
5910 methods available on the str class.
5911
R. David Murraydc6da8a2009-04-09 22:16:43 +00005912- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5917
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005918- Issue #3739: The unicode-internal encoder now reports the number of characters

Benjamin Peterson8f76b492009-04-03 22:22:42 +00006056- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
6057
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006058- Issue #5499: The 'c' code for argument parsing functions now only accepts a

6077
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006078- Issue #4688: Add a heuristic so that tuples and dicts containing only
6079 untrackable objects are not tracked by the garbage collector. This can
6080 reduce the size of collections and therefore the garbage collection overhead
6081 on long-running programs, depending on their particular use of datatypes.

6088 2**15 for the internal representation of integers, for performance
6089 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6090 --enable-big-digits option to configure, which overrides the
6091 default. Add sys.int_info structseq to provide information about
6092 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00006094- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6095 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6096 and sizeof(Py_UNICODE) == 2.
6097
Eric Smith8ec90442009-03-14 12:29:34 +00006098- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00006204- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6205 it now forces its argument to double before testing for infinity.
6206
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006207- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6208 returns a non-number type.
6209
Benjamin Peterson87618552009-02-08 15:00:52 +00006210- Issue #5182: Removed memoryview.__str__.
6211
Mark Dickinsonc008a172009-02-01 13:59:22 +00006212- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6213 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006216
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006217- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006218 were suppressing all exceptions. These include list() and bytearray().
6219
Mark Dickinson1124e712009-01-28 21:25:58 +00006220- Issue #4707: round(x, n) now returns an integer if x is an integer.
6221 Previously it returned a float.
6222
Antoine Pitroub52ec782009-01-25 16:34:23 +00006223- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6224 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6225 evaluation loop is compiled with a new dispatch mechanism which gives
6226 speedups of up to 20%, depending on the system, on various benchmarks.
6227
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006228- Issue #4874: Most builtin decoders now reject unicode input.

6236 optional module state data.
6237
Mark Dickinson8055afd2009-01-17 10:04:45 +00006238- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006239 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006240
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006241- Issue #4935: The overflow checking code in the expandtabs() method common
6242 to str, bytes and bytearray could be optimized away by the compiler, letting
6243 the interpreter segfault instead of raising an error.
6244
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006245- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6246 __next__ method.
6247
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006248- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6249 function no longer attempt to call the __long__ slot to convert an object
6250 to an integer. Only the __int__ and __trunc__ slots are examined.
6251
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006252- Issue #4893: Use NT threading on CE.
6253

6255
Antoine Pitrouab868312009-01-10 15:40:25 +00006256- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6257 common cases are optimized thanks to a dedicated fast path and a moderate
6258 amount of loop unrolling.
6259
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006260- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6261 collecting the oldest generation) so that allocating lots of objects without
6262 destroying them does not show quadratic performance. Based on a proposal by
6263 Martin von Löwis at
6264 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6265
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006266- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006267 having been closed (for instance, a read() call could return some
6268 previously buffered data). Patch by Dmitry Vasiliev.
6269
Antoine Pitrou05608432009-01-09 18:53:14 +00006270- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6271 flag to work properly. Furthermore, when specifying -u, the text stdout
6272 and stderr streams have line-by-line buffering enabled (the default being
6273 to buffer arbitrary chunks of data).
6274
Raymond Hettinger35631532009-01-09 03:58:09 +00006275- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6276 instead of ints (reducing its size from 4 to 8 times thereby reducing
6277 Python's overall memory).
6278
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006279- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6280 an existing .py counterpart, override the co_filename attributes of all
6281 code objects if the original filename is obsolete (which can happen if the
6282 file has been renamed, moved, or if it is accessed through different paths).
6283 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6284
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006285- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6286 one byte. Also fixes the meaning of len() so that it returns the number of
6287 items, rather than the size in bytes.
6288
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006289- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6290
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006291- Issue #4747: When the terminal does not use utf-8, executing a script with
6292 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6293
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006294- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6295 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006296
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006297- Issue #3680: Reference cycles created through a dict, set or deque iterator
6298 did not get collected.
6299
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006300- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6301 where the tp_hash and tp_dict slots are both NULL.
6302
Georg Brandlccc47b62008-12-28 11:44:14 +00006303- Issue #4759: None is now allowed as the first argument of
6304 bytearray.translate(). It was always allowed for bytes.translate().
6305
Skip Montanaro80072cb2008-12-23 03:51:14 +00006306- Added test case to ensure attempts to read from a file opened for writing
6307 fail.
6308
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006309- Issue #3106: Speedup some comparisons (str/str and int/int).

6312 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6313
Antoine Pitrou621601a2008-12-17 23:18:19 +00006314- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6315 print elapsed times, not only when some objects are uncollectable /
6316 unreachable. Original patch by Neil Schemenauer.
6317
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006318- Issue #3439: Add a bit_length method to int.
6319
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006320- Issue #2173: When getting device encoding, check that return value of
6321 nl_langinfo is not the empty string. This was causing silent build
6322 failures on OS X.
6323
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006324- Issue #4597: Fixed several opcodes that weren't always propagating
6325 exceptions.
6326
6327- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006328 context manager returns a value that cannot be converted to a bool.
6329
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006330- Issue #4445: Replace "sizeof(PyBytesObject)" with
6331 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6332 bytes instances. On a typical machine this saves 3 bytes of memory
6333 (on average) per allocation of a bytes instance.
6334
Christian Heimesa872de52008-12-05 08:26:55 +00006335- Issue #4533: File read operation was dreadfully slow due to a slowly
6336 growing read buffer. Fixed by using the same growth rate algorithm as
6337 Python 2.x.
6338
Antoine Pitrou5504e892008-12-06 21:27:53 +00006339- Issue #4509: Various issues surrounding resize of bytearray objects to
6340 which there are buffer exports (e.g. memoryview instances).
6341
Georg Brandlf9734072008-12-07 15:30:06 +00006342- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6343 method on file objects with closefd=False. The file descriptor is still
6344 kept open but the file object behaves like a closed file. The ``FileIO``
6345 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006346
Antoine Pitroubc420402008-12-07 20:14:49 +00006347- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6348 larger than 1.

6353
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006354- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6355 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6356 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6357 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006959- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6960 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006962- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6963 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6964 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6965 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006967- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006968 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006969 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006971- Issue #5083: New 'gui' resource for regrtest.
