736 environment after Distutils set it. Instead, have Distutils set the the
737 deployment target only in the environment of each build subprocess. It is
738 still possible to globally override the default by setting
739 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
740 greater or equal to the default value, the value with which the interpreter
741 was built.

Raymond Hettingera63a3122011-01-26 20:34:14 +00001445- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
1446 keyword-only argument. The preceding positional argument was deprecated,
1447 so it made no sense to add filter as a positional argument.
1448
Raymond Hettinger512d2cc2011-01-25 21:32:39 +00001449- Issue #11004: Repaired edge case in deque.count().

Victor Stinnerf2e439f2011-01-23 00:11:58 +00001461- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +00001462 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1463 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001464 for all file entries in the ZIP file.

1473
Armin Ronacher8d96d772011-01-22 13:13:05 +00001474- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1475 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1476 of HTTP 1.1.
1477
Armin Ronacher59531282011-01-22 13:44:22 +00001478- To match the behaviour of HTTP server, the HTTP client library now also
1479 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1480 that for incoming headers which makes this behaviour now consistent in
1481 both incoming and outgoing direction.

1518 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser

1526
Victor Stinnerdc555402011-01-04 13:15:39 +00001527- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001581- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001582 continuation line in the formatted value has no leading white space and looks
1583 like a header. Since Generator uses Header to format all headers, this check
1584 is made for all headers in any serialized message at serialization time. This
1585 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001586
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001587- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +00001593- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001594 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001595 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001596
Éric Araujof0ab5d62011-05-29 03:43:59 +02001597- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001598 rfc2047-encoding header values with embedded newlines, leaving them without
1599 folding whitespace. It now uses the continuation_ws, as it does for
1600 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001602- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1603 time.asctime(), time.ctime() and time.strftime() functions will now format
1604 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1605 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1606 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1607 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Antoine Pitroue85da7a2011-01-06 18:25:55 +00001609- Issue #7858: Raise an error properly when os.utime() fails under Windows

1616 compilation (if the input is a string).
1617
Antoine Pitrou600232b2011-01-05 21:03:42 +00001618- Issue #7995: When calling accept() on a socket with a timeout, the returned

2586
Victor Stinner257d38f2010-10-09 10:12:11 +00002587- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002590- ast.literal_eval() can now handle negative numbers. It is also a little more

2621 Py_Initialize().
2622
Georg Brandl27a28582010-10-10 09:49:21 +00002623- All SyntaxErrors now have a column offset and therefore a caret when the error

Nick Coghlan37ee8502010-12-03 14:26:13 +00002629- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002632- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2633 with a non-empty format string. This is an effort to future-proof user
2634 code. If a derived class does not currently implement __format__ but later
2635 adds its own __format__, it would most likely break user code that had
2636 supplied a format string. This will be changed to a DeprecationWaring in
2637 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002639- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2641 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002643- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2644 functions from the libc caused the methods .upper() and lower() to become
2645 locale aware and created subtly wrong results.
2646
Georg Brandl27a28582010-10-10 09:49:21 +00002647- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2648 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002649
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002650- Issue #4617: Previously it was illegal to delete a name from the local
2651 namespace if it occurs as a free variable in a nested block. This limitation
2652 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2653
Georg Brandl27a28582010-10-10 09:49:21 +00002654- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2655 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2656 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2657 single character on UCS-2 builds.

2660 underlying buffer (previously this was only done when deallocating the
2661 memoryview), and gain support for the context management protocol.
2662
Antoine Pitrou079ce542010-09-08 12:37:10 +00002663- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

2691
Éric Araujoef777bd2010-10-05 00:04:20 +00002692- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002693 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002694 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002695 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002720 retry the select() loop instead of bailing out. This is because select() can

Georg Brandl27a28582010-10-10 09:49:21 +00002803 it possible for the user to create self-referencing ordered dictionaries which
2804 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002805 approach of using weakref proxies so that reference cycles never get created
2806 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002849 * Update the seed() method to use all of the bits in a string instead of just
2850 the hash value. This makes better use of the seed value and assures the
2851 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002853 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2854 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2855 which has a slight bias whenever n is not a power of two. Issue #9025.

2857 * Improved documentation of arguments to randrange(). Issue #9379.

2878 guaranteed to exist in all Python implementations and the names of hash
2879 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00002971- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2972 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002984- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2985 now removed, since their effect was inexistent in 3.x (the default encoding is
2986 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002987
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002988- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

Georg Brandl649971e2010-09-05 17:06:50 +00002991- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2992 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002993

3008 return characters from the full Unicode range, even on narrow unicode builds
3009 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3010 in Python is that unicodedata.numeric() now returns the correct value for
3011 large code points, and repr() may consider more characters as printable.
3012
Victor Stinner6c00c142010-08-17 23:37:11 +00003013- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
3014 as a unicode object, instead of a byte string. Function needed to support
3015 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3016 function.
3017
Victor Stinner6961bd62010-08-17 22:26:51 +00003018- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

3021
Georg Brandl649971e2010-09-05 17:06:50 +00003022- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
3023 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00003024

3026 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00003027 sys.stderr.
3028
Victor Stinner47fcb5b2010-08-13 23:59:58 +00003029- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003030 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3031 objects are output as-is.

3035 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003036
Georg Brandl649971e2010-09-05 17:06:50 +00003037- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3038 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003039
Georg Brandl649971e2010-09-05 17:06:50 +00003040- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
3041 array.

Georg Brandl649971e2010-09-05 17:06:50 +00003045- Issue #9337: The str() of a float or complex number is now identical to its
3046 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003047
Georg Brandl649971e2010-09-05 17:06:50 +00003048- Issue #9416: Fix some issues with complex formatting where the output with no
3049 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003050
3051 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3052 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3395 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3396 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions

Victor Stinner25e8ec42010-06-25 00:02:38 +00003420- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3421 "w*" format instead. Add tests for "w*" format.
3422
Victor Stinner06e49dd2010-06-13 18:21:50 +00003423- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003424 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003425 string formats.
3426
Georg Brandl62069d32010-07-31 08:56:11 +00003427- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003428 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3429 location of the raised exception.
3430
Victor Stinner313a1202010-06-11 23:56:51 +00003431- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3432 filenames and enable os.fsencode().
3433
Benjamin Peterson285a6892010-06-22 19:21:52 +00003434- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3435
Georg Brandl62069d32010-07-31 08:56:11 +00003436- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3437 interpreter with characters outside the Basic Multilingual Plane (higher than
3438 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003439
Georg Brandl62069d32010-07-31 08:56:11 +00003440- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3441 TypeError instead of giving a DeprecationWarning when a float is parsed using
3442 the 'L' code (for long long). (All other integer codes already raise
3443 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003444
Victor Stinner600d3be2010-06-10 12:00:55 +00003445- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3446 enable shortcuts for upper case encoding name. Add also a shortcut for
3447 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3448
Georg Brandl62069d32010-07-31 08:56:11 +00003449- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3450 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003451
3452- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003453 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003454 like bytearray.
3455
Georg Brandl62069d32010-07-31 08:56:11 +00003456- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003457 used anymore and it was never documented.
3458
Georg Brandl62069d32010-07-31 08:56:11 +00003459- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003460
Georg Brandl62069d32010-07-31 08:56:11 +00003461- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3462 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003463
Georg Brandl62069d32010-07-31 08:56:11 +00003464- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3465 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3466 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3467 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003468
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003469- Issue #8748: Fix two issues with comparisons between complex and integer
3470 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003471 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3472 (2) The comparison raised an OverflowError for large integers, leading to
3473 unpredictable exceptions when combining integers and complex objects in sets
3474 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003475
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003476- Issue #8766: Initialize _warnings module before importing the first module.
3477 Fix a crash if an empty directory called "encodings" exists in sys.path.
3478
Victor Stinner9ca9c252010-05-19 16:53:30 +00003479- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003480 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003481 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003482
Georg Brandl62069d32010-07-31 08:56:11 +00003483- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3484 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003485
Victor Stinnerae6265f2010-05-15 16:27:27 +00003486- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3487 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003488 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003489 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003490
Victor Stinner59e62db2010-05-15 13:14:32 +00003491- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003492 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003493
Victor Stinnerb744ba12010-05-15 12:27:16 +00003494- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003495 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003496 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3497
Victor Stinner0964ee12010-04-30 16:48:45 +00003498- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003499 PyUnicode_FromString() to support surrogates in the filename and use the right
3500 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003501
Georg Brandl8569e582010-05-19 20:57:08 +00003502- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3503
Georg Brandl62069d32010-07-31 08:56:11 +00003504- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003505
Benjamin Petersonfb886362010-04-24 18:21:17 +00003506- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3507 arguments.
3508
Victor Stinner14284c22010-04-23 12:02:30 +00003509- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003510 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3511 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003512
Victor Stinner31be90b2010-04-22 19:38:16 +00003513- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00003515
Georg Brandl62069d32010-07-31 08:56:11 +00003516- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3517 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003518
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003519- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003520 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3521 compared to the dynamic memory allocation fallback. Patch by Charles-François
3522 Natali.
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003523
Benjamin Peterson8380dd52010-04-16 22:51:37 +00003524- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
3525 passed to bytes or bytearray.
3526

3530 changed.
3531
Georg Brandl62069d32010-07-31 08:56:11 +00003532- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
3533 64-bit machines. The shift count for either left or right shift is permitted
3534 to be up to sys.maxsize.

Mark Dickinsond59b4162010-03-13 11:34:40 +00003550- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
Georg Brandl62069d32010-07-31 08:56:11 +00003551 PyMemberDefs could produce an internal error; raise TypeError instead.

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003553- Issue #7845: Rich comparison methods on the complex type now return
3554 NotImplemented rather than raising a TypeError when comparing with an
3555 incompatible type; this allows user-defined classes to implement their own
3556 comparisons with complex.
3557
Victor Stinner52f6dd72010-03-12 14:45:56 +00003558- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
3559 (SIGINT). If an error occurs while importing the site module, the error is

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003603- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003604 where the right hand operand is a set of constants, by turning the set into a
3605 frozenset and pre-building it as a constant. The comparison operation is made
3606 against the constant instead of building a new set each time it is executed (a
3607 similar optimization already existed which turned a list of constants into a
3608 pre-built tuple). Patch and additional tests by Dave Malcolm.

3615 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3616 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3617 parsing certain long numeric strings corresponding to subnormal values, (3) a
3618 memory leak for some values large enough to cause overflow, and (4) a number
3619 of flaws that could lead to incorrectly rounded results.

3779
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003780- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3781 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3804 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3805 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003806 to match the behaviour of the other integer format codes.

3912 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003913 applications that use a lot of regular expressions and limits the impact of
3914 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004168- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4169 operation raises multiple signals and more than one of those signals is
4170 trapped, the specification determines the order in which the signals should be
4171 handled. In many cases this order wasn't being followed, leading to the wrong
4172 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004211- Issue #8524: When creating an SSL socket, the timeout value of the original
4212 socket wasn't retained (instead, a socket with a positive timeout would be
4213 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004214
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004215- Issue #5103: SSL handshake would ignore the socket timeout and block

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004336- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004337 argument `-` which tells it to read files to compile from stdin. Each line is
4338 read on demand and the named file is compiled immediately. (Original patch by
4339 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004345- Comparisons using one of <, <=, >, >= between a complex instance and a
4346 Fractions instance now raise TypeError instead of returning True/False. This
4347 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4348 <=> complex, and complex <=> complex comparisons.

4392 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4393 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004394
Georg Brandl62069d32010-07-31 08:56:11 +00004395- subprocess.Popen now has restore_signals and start_new_session features. The
4396 default of restore_signals=True is a new behavior compared to earlier Python
4397 versions. This means that signals such as SIGPIPE are not ignored by default
4398 in subprocesses launched by Python (Issue #1652).

4485 position when calling `truncate()`. It would previously change the file
4486 position to the given argument, which goes against the tradition of

4493 issue where interleaved calls to `read()` and `readline()` give wrong results.

4809 occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
4810 "wb+" mode) after having buffered a certain amount of data for reading. This
4811 bug was not present in the pure Python implementation.

Georg Brandl62069d32010-07-31 08:56:11 +00004818- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
4819 digits in input, as recommended by the standard. Previously it was restricted
4820 to accepting [0-9].

Brett Cannon69194272009-07-20 04:23:48 +00004829- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004830 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4831 PyPycLoader inherit from this class and provide implementations in relation to
4832 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004833
Brett Cannon64ef00f2009-07-20 03:19:18 +00004834- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4835 the documentation said it did even though the code in PyLoader relied on the
4836 abstract method required by ResourceLoader.
4837
Georg Brandl62069d32010-07-31 08:56:11 +00004838- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004886- Issue #9959: Tweak formula used for computing math.log of an integer,
4887 making it marginally more accurate for exact powers of 2.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004891- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004892 compared to other unix systems. In particular, os.getgroups() does not reflect
4893 any changes made using os.setgroups() but basicly always returns the same
4894 information as the id command. os.getgroups() can now return more than 16
4895 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004920- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4921 Prior to this change, timezone adjustment in utctimetuple() could produce
4922 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4923 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004925- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4926 directive. When the ``%z`` directive is present in the format string, an
4927 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4928 ``datetime.timezone`` instance constructed from the parsed offset. If both
4929 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4930 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004932- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004933 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4934 ``datetime.timezone``, return fixed name and UTC offset from their
4935 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4936 returns ``None``. A class attribute, ``utc`` contains an instance
4937 representing the UTC timezone. Original patch by Rafe Kaplan.

4954 with an improved 'binary-split' algorithm that uses fewer multiplications and
4955 allows many of the multiplications to be performed using plain C integer
4956 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4957 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004962- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4963 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004964 the result is now always correctly rounded, and is equivalent to ``td /
4965 timedelta(seconds=1)``.

4974 integer format code, struct.pack first attempts to convert the non-integer
4975 using its __index__ method. If that method is non-existent or raises
4976 TypeError it goes on to try the __int__ method, as described below.

5557 default precision of 12. Previously, the behavior the same but with
5558 a default precision of 6. This more closely matches str(), and
5559 reduces surprises when adding alignment flags to the empty
5560 presentation type. This also affects the new complex.__format__ in
5561 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005574- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5575 received a new method, detach(). detach() disconnects the underlying stream
5576 from the buffer or text IO and returns it.
5577
Mark Dickinson33841c32009-05-01 15:37:04 +00005578- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5579 floats with absolute value over 1e50. Also remove length
5580 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5581 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00005583- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005584 format(complex(1, 2./3), '.5') now produces a sensible result.
5585
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005586- Issue #5864: Fix empty format code formatting for floats so that it
5587 never gives more than the requested number of significant digits.
5588
Eric Smith6dc46f52009-04-27 20:39:49 +00005589- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Martin v. Löwis71efeb72009-04-26 01:02:07 +00005594- Issue #4971: Fix titlecase for characters that are their own
5595 titlecase, but not their own uppercase.
5596
Benjamin Peterson193152c2009-04-25 01:08:45 +00005597- Issue #5283: Setting __class__ in __del__ caused a segfault.
5598
Mark Dickinsonad476da2009-04-23 19:14:16 +00005599- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5600 z involves nans, infs or negative zeros.
5601
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005602- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005603
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005604- Issue #1869 (and many duplicates): make round(x, n) correctly
5605 rounded for a float x, by using the decimal <-> binary conversions
5606 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5607 consistently agrees with format(x, '.2f').
5608
Benjamin Petersonae937c02009-04-18 20:54:08 +00005609- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5610 some builtin types.
5611
Eric Smith0923d1d2009-04-16 20:16:10 +00005612- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5613
Eric Smith35e84722009-04-16 20:21:28 +00005614- Issue #5515: str.format() type 'n' combined with commas and leading
5615 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005616
5617- Implement PEP 378, Format Specifier for Thousands Separator, for
5618 floats.
5619
Mark Dickinson3370cce2009-04-17 22:40:53 +00005620- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005621 1e11, not 1e12. This avoids printing 13 significant digits in
5622 situations where only 12 of them are correct. Example problem
5623 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5624 long time.)
5625
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005626- Issue #1580: On most platforms, use a 'short' float repr: for a
5627 finite float x, repr(x) now outputs a string based on the shortest
5628 sequence of decimal digits that rounds to x. Previous behaviour was
5629 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005630 Another minor difference is that the new repr switches to
5631 exponential notation at 1e16 instead of the previous 1e17; this
5632 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005633
5634 There's a new sys attribute sys.float_repr_style, which takes
5635 the value 'short' to indicate that we're using short float repr,
5636 and 'legacy' if the short float repr isn't available for one
5637 reason or another.
5638
5639 The float repr change involves incorporating David Gay's 'perfect
5640 rounding' code into the Python core (it's in Python/dtoa.c). As a
5641 secondary consequence, all string-to-float and float-to-string
5642 conversions (including all float formatting operations) will be
5643 correctly rounded on these platforms.
5644
Georg Brandl5f90d792010-08-01 22:31:05 +00005645 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005646 this change does not apply.
5647
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005648- Issue #5759: float() didn't call __float__ on str subclasses.
5649
Georg Brandlabc38772009-04-12 15:51:51 +00005650- The string.maketrans() function is deprecated; there is a new static method
5651 maketrans() on the bytes and bytearray classes. This removes confusion about
5652 the types string.maketrans() is supposed to work with, and mirrors the
5653 methods available on the str class.
5654
R. David Murraydc6da8a2009-04-09 22:16:43 +00005655- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5656 its clarity and its speed.
5657
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005658- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005659 to avoid compiler warnings.
5660
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005661- Issue #3739: The unicode-internal encoder now reports the number of characters
5662 consumed like any other encoder (instead of the number of bytes).

5822 untrackable objects are not tracked by the garbage collector. This can
5823 reduce the size of collections and therefore the garbage collection overhead
5824 on long-running programs, depending on their particular use of datatypes.

5831 2**15 for the internal representation of integers, for performance
5832 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5833 --enable-big-digits option to configure, which overrides the
5834 default. Add sys.int_info structseq to provide information about
5835 the internal format.

5838 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5839 and sizeof(Py_UNICODE) == 2.
5840
Eric Smith8ec90442009-03-14 12:29:34 +00005841- Issue #5237: Allow auto-numbered fields in str.format(). For

5945 rotating the object pointer by 4 bits to the right.
5946
Mark Dickinson87ec0852009-02-09 17:15:59 +00005947- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5948 it now forces its argument to double before testing for infinity.
5949
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005950- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5951 returns a non-number type.
5952
Benjamin Peterson87618552009-02-08 15:00:52 +00005953- Issue #5182: Removed memoryview.__str__.
5954
Mark Dickinsonc008a172009-02-01 13:59:22 +00005955- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5956 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

5958 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005959
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005960- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005961 were suppressing all exceptions. These include list() and bytearray().
5962
Mark Dickinson1124e712009-01-28 21:25:58 +00005963- Issue #4707: round(x, n) now returns an integer if x is an integer.
5964 Previously it returned a float.
5965
Antoine Pitroub52ec782009-01-25 16:34:23 +00005966- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5967 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5968 evaluation loop is compiled with a new dispatch mechanism which gives
5969 speedups of up to 20%, depending on the system, on various benchmarks.
5970
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005971- Issue #4874: Most builtin decoders now reject unicode input.

5979 optional module state data.
5980
Mark Dickinson8055afd2009-01-17 10:04:45 +00005981- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005982 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005983
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005984- Issue #4935: The overflow checking code in the expandtabs() method common
5985 to str, bytes and bytearray could be optimized away by the compiler, letting
5986 the interpreter segfault instead of raising an error.
5987
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005988- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5989 __next__ method.
5990
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005991- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5992 function no longer attempt to call the __long__ slot to convert an object
5993 to an integer. Only the __int__ and __trunc__ slots are examined.
5994
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005995- Issue #4893: Use NT threading on CE.
5996
Martin v. Löwisec59d042009-01-12 07:59:10 +00005997- Issue #4915: Port sysmodule to Windows CE.
5998
Antoine Pitrouab868312009-01-10 15:40:25 +00005999- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6000 common cases are optimized thanks to a dedicated fast path and a moderate
6001 amount of loop unrolling.
6002
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006003- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6004 collecting the oldest generation) so that allocating lots of objects without
6005 destroying them does not show quadratic performance. Based on a proposal by
6006 Martin von Löwis at
6007 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6008
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006009- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006010 having been closed (for instance, a read() call could return some
6011 previously buffered data). Patch by Dmitry Vasiliev.
6012
Antoine Pitrou05608432009-01-09 18:53:14 +00006013- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6014 flag to work properly. Furthermore, when specifying -u, the text stdout
6015 and stderr streams have line-by-line buffering enabled (the default being
6016 to buffer arbitrary chunks of data).
6017
Raymond Hettinger35631532009-01-09 03:58:09 +00006018- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6019 instead of ints (reducing its size from 4 to 8 times thereby reducing
6020 Python's overall memory).
6021
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006022- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6023 an existing .py counterpart, override the co_filename attributes of all
6024 code objects if the original filename is obsolete (which can happen if the
6025 file has been renamed, moved, or if it is accessed through different paths).
6026 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6027
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006028- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6029 one byte. Also fixes the meaning of len() so that it returns the number of
6030 items, rather than the size in bytes.
6031
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006032- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6033
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006034- Issue #4747: When the terminal does not use utf-8, executing a script with
6035 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6036
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006037- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6038 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006039
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006040- Issue #3680: Reference cycles created through a dict, set or deque iterator
6041 did not get collected.
6042
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006043- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6044 where the tp_hash and tp_dict slots are both NULL.
6045
Georg Brandlccc47b62008-12-28 11:44:14 +00006046- Issue #4759: None is now allowed as the first argument of
6047 bytearray.translate(). It was always allowed for bytes.translate().
6048
Skip Montanaro80072cb2008-12-23 03:51:14 +00006049- Added test case to ensure attempts to read from a file opened for writing
6050 fail.
6051
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006052- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00006054- Issue #2183: Simplify and optimize bytecode for list, dict and set
6055 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6056
Antoine Pitrou621601a2008-12-17 23:18:19 +00006057- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6058 print elapsed times, not only when some objects are uncollectable /
6059 unreachable. Original patch by Neil Schemenauer.
6060
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006061- Issue #3439: Add a bit_length method to int.
6062
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006063- Issue #2173: When getting device encoding, check that return value of
6064 nl_langinfo is not the empty string. This was causing silent build
6065 failures on OS X.
6066
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006067- Issue #4597: Fixed several opcodes that weren't always propagating
6068 exceptions.
6069
6070- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006071 context manager returns a value that cannot be converted to a bool.
6072
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006073- Issue #4445: Replace "sizeof(PyBytesObject)" with
6074 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6075 bytes instances. On a typical machine this saves 3 bytes of memory
6076 (on average) per allocation of a bytes instance.
6077
Christian Heimesa872de52008-12-05 08:26:55 +00006078- Issue #4533: File read operation was dreadfully slow due to a slowly
6079 growing read buffer. Fixed by using the same growth rate algorithm as
6080 Python 2.x.
6081
Antoine Pitrou5504e892008-12-06 21:27:53 +00006082- Issue #4509: Various issues surrounding resize of bytearray objects to
6083 which there are buffer exports (e.g. memoryview instances).
6084
Georg Brandlf9734072008-12-07 15:30:06 +00006085- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6086 method on file objects with closefd=False. The file descriptor is still
6087 kept open but the file object behaves like a closed file. The ``FileIO``
6088 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006089
Antoine Pitroubc420402008-12-07 20:14:49 +00006090- Issue #4569: Interpreter crash when mutating a memoryview with an item size

6096
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006097- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6098 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6099 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6100 of using the replace error handler in PyUnicode_DecodeUTF8().
