14 fails. Patch by Suman Saha.
15
Benjamin Peterson2652d252012-01-29 20:16:37 -050016- Issue #13908: Ready types returned from PyType_FromSpec.
17
Antoine Pitrou2be60af2012-01-24 17:44:06 +010018- Issue #11235: Fix OverflowError when trying to import a source file whose

20
Antoine Pitrou6c40eb72012-01-18 20:16:09 +010021- Fix the builtin module initialization code to store the init function for
22 future reinitialization.
23
Gregory P. Smith9564e4c2012-01-21 14:50:11 -080024- Issue #8052: The posix subprocess module would take a long time closing
25 all possible file descriptors in the child process rather than just open
26 file descriptors. It now closes only the open fds if possible for the
27 default close_fds=True behavior.
28
Meador Inge33880602012-01-15 19:15:36 -060029- Issue #13629: Renumber the tokens in token.h so that they match the indexes
30 into _PyParser_TokenNames.
31
Antoine Pitrou2e872082011-12-15 14:15:31 +010032- Fix the fix for issue #12149: it was incorrect, although it had the side
33 effect of appearing to resolve the issue. Thanks to Mark Shannon for
34 noticing.
35
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050036- Issue #13505: Pickle bytes objects in a way that is compatible with

Antoine Pitrou11942a52011-11-28 19:08:36 +010042- Issue #7111: Python can now be run without a stdin, stdout or stderr
43 stream. It was already the case with Python 2. However, the corresponding
44 sys module entries are now set to None (instead of an unusable file object).
45
Amaury Forgeot d'Arc58e87612011-11-22 21:51:55 +010046- Issue #13436: Fix a bogus error message when an AST object was passed
47 an invalid integer value.
48
Petri Lehtinen8d40f162011-11-19 22:03:10 +020049- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
50 to allow compiling extension modules with -Wswitch-enum on gcc.

52
Antoine Pitrou5418ee02011-11-15 01:42:21 +010053- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
54 already accepts them).
55
Antoine Pitrou0d776b12011-11-06 00:34:26 +010056- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
57 error handler in interactive mode (when calling into PyOS_Readline()).
58

61 (lambda *, arg=GLOBAL_NAME: None)
62
Petri Lehtinencd06a142011-10-30 20:59:10 +020063- Issue #10519: Avoid unnecessary recursive function calls in
64 setobject.c.
65

Nick Coghlande31b192011-10-23 22:04:16 +100071- Issue #1294232: In a few cases involving metaclass inheritance, the
72 interpreter would sometimes invoke the wrong metaclass when building a new
73 class object. These cases now behave correctly. Patch by Daniel Urban.
74
Senthil Kumaranfdd45752011-10-21 00:29:47 +080075- Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler
76 warnings. Patch by Josh Triplett and Petri Lehtinen.
77
Antoine Pitrou551ba202011-10-18 16:40:50 +020078- Issue #13188: When called without an explicit traceback argument,
79 generator.throw() now gets the traceback from the passed exception's
80 ``__traceback__`` attribute. Patch by Petri Lehtinen.
81
Mark Hammond6c58b282011-10-17 11:05:57 +110082- Issue #7833: Extension modules built using distutils on Windows will no
83 longer include a "manifest" to prevent them failing at import time in some
84 embedded situations.
85

145
Ned Deily99377482012-02-10 13:01:08 +0100146- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
147 Distutils-based packages with C extension modules may fail because
148 Apple has removed gcc-4.2, the version used to build python.org
149 64-bit/32-bit Pythons. If the user does not explicitly override
150 the default C compiler by setting the CC environment variable,
151 Distutils will now attempt to compile extension modules with clang
152 if gcc-4.2 is required but not found. Also as a convenience, if
153 the user does explicitly set CC, substitute its value as the default
154 compiler in the Distutils LDSHARED configuration variable for OS X.
155 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
156 SDK, neither of which are available in Xcode 4. This change does not
157 attempt to override settings to support their use with Xcode 4.)
158
Ezio Melottifa3702d2012-02-10 10:45:44 +0200159- Issue #13960: HTMLParser is now able to handle broken comments when

163
Senthil Kumaran6e13f132012-02-09 17:54:17 +0800164- Issue #6005: Examples in the socket library documentation use sendall, where
165 relevant, instead send method.
166
Petri Lehtinen4a84f582011-05-09 12:24:09 +0200167- Issue #10811: Fix recursive usage of cursors. Instead of crashing,

169

200 target's type (file or directory). The detection was buggy and made the
201 call non-atomic (therefore prone to race conditions).

866 and was unreliable since tests or user programs could modify the interpreter
867 environment after Distutils set it. Instead, have Distutils set the the
868 deployment target only in the environment of each build subprocess. It is
869 still possible to globally override the default by setting
870 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be

872 was built.

1714 like a header. Since Generator uses Header to format all headers, this check
1715 is made for all headers in any serialized message at serialization time. This
1716 provides protection against header injection attacks.

R. David Murray92532142011-01-07 23:25:30 +00001727
Éric Araujof0ab5d62011-05-29 03:43:59 +02001728- email.header.Header was incorrectly encoding folding whitespace when

1730 folding whitespace. It now uses the continuation_ws, as it does for
1731 continuation lines that it creates itself.

1736 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range

1738 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002369 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002370 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002484 incorrectly validated some non-compliant applications as WSGI compliant; if
2485 your app validates with Python <3.2b1+, but not on this version, it is likely
2486 the case that your app was not compliant.)

2764 with a non-empty format string. This is an effort to future-proof user
2765 code. If a derived class does not currently implement __format__ but later
2766 adds its own __format__, it would most likely break user code that had
2767 supplied a format string. This will be changed to a DeprecationWaring in
2768 Python 3.3 and it will be an error in Python 3.4.

2783 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

Georg Brandl27a28582010-10-10 09:49:21 +00002785- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2787 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2788 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002823- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002824 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002825 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002826 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002966- Issue #9792: In case of connection failure, socket.create_connection() would
2967 swallow the exception and raise a new one, making it impossible to fetch the
2968 original errno, or to filter timeout errors. Now the original error is
2969 re-raised.

2972 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2973 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002975- Updates to the random module:
2976
Georg Brandl27a28582010-10-10 09:49:21 +00002977 * Document which parts of the module are guaranteed to stay the same across
2978 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002980 * Update the seed() method to use all of the bits in a string instead of just
2981 the hash value. This makes better use of the seed value and assures the
2982 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002984 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2985 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2986 which has a slight bias whenever n is not a power of two. Issue #9025.

3009 guaranteed to exist in all Python implementations and the names of hash
3010 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003115- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3116 now removed, since their effect was inexistent in 3.x (the default encoding is

3139 return characters from the full Unicode range, even on narrow unicode builds
3140 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3141 in Python is that unicodedata.numeric() now returns the correct value for
3142 large code points, and repr() may consider more characters as printable.
3143
Victor Stinner6c00c142010-08-17 23:37:11 +00003144- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003179- Issue #9416: Fix some issues with complex formatting where the output with no
3180 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003181
3182 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003522- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003523 start byte and the continuation byte(s) are now considered invalid, instead of
3524 the number of bytes specified by the start byte. E.g.:
3525 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3526 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3527 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3528 returned a single u'\ufffd'.

3531 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3543 dealing with unary minus applied to a constant. The removed code was mutating
3544 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003548 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003549 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003550
Victor Stinner25e8ec42010-06-25 00:02:38 +00003551- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3552 "w*" format instead. Add tests for "w*" format.
3553
Victor Stinner06e49dd2010-06-13 18:21:50 +00003554- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003555 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003556 string formats.
3557
Georg Brandl62069d32010-07-31 08:56:11 +00003558- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003559 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3560 location of the raised exception.
3561
Victor Stinner313a1202010-06-11 23:56:51 +00003562- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3563 filenames and enable os.fsencode().
3564
Benjamin Peterson285a6892010-06-22 19:21:52 +00003565- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3566
Georg Brandl62069d32010-07-31 08:56:11 +00003567- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3568 interpreter with characters outside the Basic Multilingual Plane (higher than
3569 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003570
Georg Brandl62069d32010-07-31 08:56:11 +00003571- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3572 TypeError instead of giving a DeprecationWarning when a float is parsed using
3573 the 'L' code (for long long). (All other integer codes already raise
3574 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003575
Victor Stinner600d3be2010-06-10 12:00:55 +00003576- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3577 enable shortcuts for upper case encoding name. Add also a shortcut for
3578 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3579
Georg Brandl62069d32010-07-31 08:56:11 +00003580- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3581 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003582
3583- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003584 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003585 like bytearray.
3586
Georg Brandl62069d32010-07-31 08:56:11 +00003587- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003588 used anymore and it was never documented.
3589
Georg Brandl62069d32010-07-31 08:56:11 +00003590- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003591
Georg Brandl62069d32010-07-31 08:56:11 +00003592- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3593 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003594
Georg Brandl62069d32010-07-31 08:56:11 +00003595- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3596 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3597 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3598 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003599
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003600- Issue #8748: Fix two issues with comparisons between complex and integer
3601 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003602 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3603 (2) The comparison raised an OverflowError for large integers, leading to
3604 unpredictable exceptions when combining integers and complex objects in sets
3605 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003606
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003607- Issue #8766: Initialize _warnings module before importing the first module.
3608 Fix a crash if an empty directory called "encodings" exists in sys.path.
3609
Victor Stinner9ca9c252010-05-19 16:53:30 +00003610- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003611 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003612 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003613
Georg Brandl62069d32010-07-31 08:56:11 +00003614- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3615 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003616
Victor Stinnerae6265f2010-05-15 16:27:27 +00003617- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3618 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003619 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003620 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003621
Victor Stinner59e62db2010-05-15 13:14:32 +00003622- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003623 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003624
Victor Stinnerb744ba12010-05-15 12:27:16 +00003625- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003626 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003627 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3628
Victor Stinner0964ee12010-04-30 16:48:45 +00003629- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003630 PyUnicode_FromString() to support surrogates in the filename and use the right
3631 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003632
Georg Brandl8569e582010-05-19 20:57:08 +00003633- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3634
Georg Brandl62069d32010-07-31 08:56:11 +00003635- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003636
Benjamin Petersonfb886362010-04-24 18:21:17 +00003637- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3638 arguments.
3639
Victor Stinner14284c22010-04-23 12:02:30 +00003640- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003641 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003684- Issue #7845: Rich comparison methods on the complex type now return
3685 NotImplemented rather than raising a TypeError when comparing with an
3686 incompatible type; this allows user-defined classes to implement their own

Antoine Pitroufc8d6f42010-01-17 12:38:54 +00003733
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003734- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003735 where the right hand operand is a set of constants, by turning the set into a
3736 frozenset and pre-building it as a constant. The comparison operation is made
3737 against the constant instead of building a new set each time it is executed (a
3738 similar optimization already existed which turned a list of constants into a
3739 pre-built tuple). Patch and additional tests by Dave Malcolm.

3746 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3747 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3748 parsing certain long numeric strings corresponding to subnormal values, (3) a
3749 memory leak for some values large enough to cause overflow, and (4) a number
3750 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003764- Issue #1811: improve accuracy and cross-platform consistency for true division
3765 of integers: the result of a/b is now correctly rounded for ints a and b (at
3766 least on IEEE 754 platforms), and in particular does not depend on the
3767 internal representation of an int.
Mark Dickinsoncbb62742009-12-27 15:09:50 +00003768
Ronald Oussoren6f6c5622009-12-24 14:03:19 +00003769- Issue #6834: replace the implementation for the 'python' and 'pythonw'

3771
Georg Brandl62069d32010-07-31 08:56:11 +00003772 These executables now work properly with the arch(1) command: ``arch -ppc

3792
Georg Brandl62069d32010-07-31 08:56:11 +00003793- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
3794 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
3795 long but the length of the range did not. Also fix several cases where
3796 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
3797 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003907- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3908 variable argument list. `Py_VA_COPY` is equivalent to C99
3909 `va_copy`, but available on all python platforms.
3910
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003911- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3912 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3913 "step = -step" when reversing a slice.
3914
Georg Brandl62069d32010-07-31 08:56:11 +00003915- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
3916 interpreter to set sys.argv without also modifying sys.path. This helps fix
3917 `CVE-2008-5983
Antoine Pitrouf978fac2010-05-21 17:25:34 +00003918 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
3919
Benjamin Petersonfb886362010-04-24 18:21:17 +00003920- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
3921 strings in an efficient manner.
3922
Antoine Pitrou8689a102010-04-01 16:53:15 +00003923- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003924 function declaration, which was kept for backwards compatibility reasons, is
3925 now removed (the macro was introduced in 1997!).
Antoine Pitrou8689a102010-04-01 16:53:15 +00003926
Georg Brandl62069d32010-07-31 08:56:11 +00003927- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to
3928 PyLong_AsLongAndOverflow.

Georg Brandl62069d32010-07-31 08:56:11 +00003934 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
3935 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3936 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003937 to match the behaviour of the other integer format codes.
3938
Georg Brandl62069d32010-07-31 08:56:11 +00003939- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00003947- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3948 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3949 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00003950

3962 ``const char *`` as the string is stored beyond the call.
3963
Georg Brandl62069d32010-07-31 08:56:11 +00003964- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3965 allocator will be automatically disabled when running under Valgrind. This
3966 gives improved memory leak detection when running under Valgrind, while taking
3967 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004040- The default size of the re module's compiled regular expression cache has been
4041 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004042 simply clearing the entire cache on overflow to forgetting the least recently
4043 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004044 applications that use a lot of regular expressions and limits the impact of
4045 the performance hit anytime the cache is exceeded.

4058 module is renamed to `_datetime` and if available, overrides all classes
4059 defined in datetime with fast C impementation. Python implementation is based
4060 on the original python prototype for the datetime module by Tim Peters with
4061 minor modifications by the PyPy project. The test suite now tests `datetime`
4062 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004417- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004418 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004419 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004443- Add functools.total_ordering() and functools.cmp_to_key().
4444
Georg Brandl62069d32010-07-31 08:56:11 +00004445- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00004454- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4455 InvalidOperation instead of returning False. (Comparisons involving a quiet
4456 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4457 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004459- Issue #2531: Comparison operations between floats and Decimal instances now
4460 return a result based on the numeric values of the operands; previously they
4461 returned an arbitrary result based on the relative ordering of id(float) and
4462 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4463 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004464
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004465- Added a subtract() method to collections.Counter().
4466
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004467- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004468 argument `-` which tells it to read files to compile from stdin. Each line is
4469 read on demand and the named file is compiled immediately. (Original patch by
4470 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004472- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004476- Comparisons using one of <, <=, >, >= between a complex instance and a
4477 Fractions instance now raise TypeError instead of returning True/False. This
4478 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4479 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004522- The internals of the subprocess module on POSIX systems have been replaced by
4523 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4524 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004525
Georg Brandl62069d32010-07-31 08:56:11 +00004526- subprocess.Popen now has restore_signals and start_new_session features. The
4527 default of restore_signals=True is a new behavior compared to earlier Python
4528 versions. This means that signals such as SIGPIPE are not ignored by default
4529 in subprocesses launched by Python (Issue #1652).

4616 position when calling `truncate()`. It would previously change the file
4617 position to the given argument, which goes against the tradition of

4622 archive. The new implementation is significantly faster and can be wrapped in
4623 a :class:`io.BufferedReader` object for more speedups. It also solves an
4624 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00004827- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
4828 from stdin so that existing input does not confuse it and lead to incorrect
4829 entry or an IOError. It also properly flushes it afterwards to avoid the
4830 terminal echoing the input afterwards on OSes such as Solaris.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005022- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005023 compared to other unix systems. In particular, os.getgroups() does not reflect

5568 didn't match that of float('-nan').

5619 library. This means, for example, that opening an UTF-16 text file in
5620 append mode doesn't add a BOM at the end of the file if the file isn't
5621 empty.

5671Core and Builtins
5672-----------------
5673
Mark Dickinson865e01a2009-05-07 16:37:01 +00005674- Issue #5914: Add new C API function PyOS_string_to_double, and
5675 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5676
Eric Smith741191f2009-05-06 13:08:15 +00005677- Issue #3382: float.__format__, complex.__format__, and %-formatting
5678 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5679 affects nan -> NAN and inf -> INF.
5680
Mark Hammond5a607a32009-05-06 08:04:54 +00005681- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5682 in all operations, including splitdrive, split, etc. splitunc() now issues
5683 a PendingDeprecation warning.
5684
Eric Smith63376222009-05-05 14:04:18 +00005685- Issue #5920: For float.__format__, change the behavior with the
5686 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5687 to be like 'g' but with at least one decimal point and with a
5688 default precision of 12. Previously, the behavior the same but with
5689 a default precision of 6. This more closely matches str(), and
5690 reduces surprises when adding alignment flags to the empty
5691 presentation type. This also affects the new complex.__format__ in
5692 the same way.
5693
Martin v. Löwis011e8422009-05-05 04:43:17 +00005694- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5695
R. David Murrayb18500d2009-05-04 22:59:07 +00005696- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5697 shadowed by classtype's, even if it was None. property now
5698 inserts the __doc__ into the subclass instance __dict__.
5699
Antoine Pitrou244651a2009-05-04 18:56:13 +00005700- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5701 sequences. Patch by Nick Barnes and Victor Stinner.
5702
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005703- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005704
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005705- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5706 received a new method, detach(). detach() disconnects the underlying stream
5707 from the buffer or text IO and returns it.
5708
Mark Dickinson33841c32009-05-01 15:37:04 +00005709- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5710 floats with absolute value over 1e50. Also remove length
5711 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5712 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005713
Eric Smith741191f2009-05-06 13:08:15 +00005714- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005715 format(complex(1, 2./3), '.5') now produces a sensible result.
5716
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005717- Issue #5864: Fix empty format code formatting for floats so that it
5718 never gives more than the requested number of significant digits.
5719
Eric Smith6dc46f52009-04-27 20:39:49 +00005720- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5721 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5722
Eric Smithcc32a112009-04-26 21:35:14 +00005723- Issue #5835: Deprecate PyOS_ascii_formatd.
5724
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005725- Issue #4971: Fix titlecase for characters that are their own
5726 titlecase, but not their own uppercase.
5727
Benjamin Peterson193152c2009-04-25 01:08:45 +00005728- Issue #5283: Setting __class__ in __del__ caused a segfault.
5729
Mark Dickinsonad476da2009-04-23 19:14:16 +00005730- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5731 z involves nans, infs or negative zeros.
5732
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005733- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005734
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005735- Issue #1869 (and many duplicates): make round(x, n) correctly
5736 rounded for a float x, by using the decimal <-> binary conversions
5737 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5738 consistently agrees with format(x, '.2f').
5739
Benjamin Petersonae937c02009-04-18 20:54:08 +00005740- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5741 some builtin types.
5742
Eric Smith0923d1d2009-04-16 20:16:10 +00005743- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5744
Eric Smith35e84722009-04-16 20:21:28 +00005745- Issue #5515: str.format() type 'n' combined with commas and leading
5746 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005747
5748- Implement PEP 378, Format Specifier for Thousands Separator, for
5749 floats.
5750
Mark Dickinson3370cce2009-04-17 22:40:53 +00005751- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005752 1e11, not 1e12. This avoids printing 13 significant digits in
5753 situations where only 12 of them are correct. Example problem
5754 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5755 long time.)
5756
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005757- Issue #1580: On most platforms, use a 'short' float repr: for a
5758 finite float x, repr(x) now outputs a string based on the shortest
5759 sequence of decimal digits that rounds to x. Previous behaviour was
5760 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005761 Another minor difference is that the new repr switches to
5762 exponential notation at 1e16 instead of the previous 1e17; this
5763 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005764
5765 There's a new sys attribute sys.float_repr_style, which takes
5766 the value 'short' to indicate that we're using short float repr,
5767 and 'legacy' if the short float repr isn't available for one
5768 reason or another.
5769
5770 The float repr change involves incorporating David Gay's 'perfect
5771 rounding' code into the Python core (it's in Python/dtoa.c). As a
5772 secondary consequence, all string-to-float and float-to-string
5773 conversions (including all float formatting operations) will be
5774 correctly rounded on these platforms.
5775
Georg Brandl5f90d792010-08-01 22:31:05 +00005776 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005777 this change does not apply.
5778
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005779- Issue #5759: float() didn't call __float__ on str subclasses.
5780
Georg Brandlabc38772009-04-12 15:51:51 +00005781- The string.maketrans() function is deprecated; there is a new static method
5782 maketrans() on the bytes and bytearray classes. This removes confusion about
5783 the types string.maketrans() is supposed to work with, and mirrors the
5784 methods available on the str class.
5785
R. David Murraydc6da8a2009-04-09 22:16:43 +00005786- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5787 its clarity and its speed.
5788
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005789- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005790 to avoid compiler warnings.
5791
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005792- Issue #3739: The unicode-internal encoder now reports the number of characters
5793 consumed like any other encoder (instead of the number of bytes).

6146 and stderr streams have line-by-line buffering enabled (the default being
6147 to buffer arbitrary chunks of data).
6148
Raymond Hettinger35631532009-01-09 03:58:09 +00006149- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6150 instead of ints (reducing its size from 4 to 8 times thereby reducing
6151 Python's overall memory).
6152
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006153- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6154 an existing .py counterpart, override the co_filename attributes of all
6155 code objects if the original filename is obsolete (which can happen if the
6156 file has been renamed, moved, or if it is accessed through different paths).
6157 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6158
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006159- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6160 one byte. Also fixes the meaning of len() so that it returns the number of
6161 items, rather than the size in bytes.
6162

Georg Brandlccc47b62008-12-28 11:44:14 +00006177- Issue #4759: None is now allowed as the first argument of

6179

Mark Dickinsonfd24b322008-12-06 15:33:31 +00006204- Issue #4445: Replace "sizeof(PyBytesObject)" with
6205 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

6208
Christian Heimesa872de52008-12-05 08:26:55 +00006209- Issue #4533: File read operation was dreadfully slow due to a slowly

6211 Python 2.x.
6212
Antoine Pitrou5504e892008-12-06 21:27:53 +00006213- Issue #4509: Various issues surrounding resize of bytearray objects to

6215
Georg Brandlf9734072008-12-07 15:30:06 +00006216- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6217 method on file objects with closefd=False. The file descriptor is still
6218 kept open but the file object behaves like a closed file. The ``FileIO``
6219 object also got a new readonly attribute ``closefd``.

6229 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6230 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6231 of using the replace error handler in PyUnicode_DecodeUTF8().

6550
Antoine Pitrou08838b62009-01-21 00:55:13 +00006551- Issue #5008: When a file is opened in append mode with the new IO library,
6552 do an explicit seek to the end of file (so that e.g. tell() returns the
6553 file size rather than 0). This is consistent with the behaviour of the

6584 appropriately when it is being used via socket.makefile() objects
6585 rather than delaying the close by waiting for garbage collection to do it.
6586
