Ned Deily657b2de2011-06-28 19:51:30 -0700577- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
578 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
579 interpreter process. This could cause failures in non-Distutils subprocesses
580 and was unreliable since tests or user programs could modify the interpreter
581 environment after Distutils set it. Instead, have Distutils set the the
582 deployment target only in the environment of each build subprocess. It is
583 still possible to globally override the default by setting
584 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
585 greater or equal to the default value, the value with which the interpreter
586 was built.

1428 like a header. Since Generator uses Header to format all headers, this check
1429 is made for all headers in any serialized message at serialization time. This
1430 provides protection against header injection attacks.

R. David Murray92532142011-01-07 23:25:30 +00001441
Éric Araujof0ab5d62011-05-29 03:43:59 +02001442- email.header.Header was incorrectly encoding folding whitespace when

1444 folding whitespace. It now uses the continuation_ws, as it does for
1445 continuation lines that it creates itself.

1450 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1451 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1452 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002083 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002084 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002198 incorrectly validated some non-compliant applications as WSGI compliant; if
2199 your app validates with Python <3.2b1+, but not on this version, it is likely
2200 the case that your app was not compliant.)

Georg Brandl27a28582010-10-10 09:49:21 +00002468- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002477- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2478 with a non-empty format string. This is an effort to future-proof user
2479 code. If a derived class does not currently implement __format__ but later
2480 adds its own __format__, it would most likely break user code that had
2481 supplied a format string. This will be changed to a DeprecationWaring in
2482 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002484- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2486 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 +00002488- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2489 functions from the libc caused the methods .upper() and lower() to become

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002495- Issue #4617: Previously it was illegal to delete a name from the local
2496 namespace if it occurs as a free variable in a nested block. This limitation
2497 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2498
Georg Brandl27a28582010-10-10 09:49:21 +00002499- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2501 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2502 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002537- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002538 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002539 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002540 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002680- Issue #9792: In case of connection failure, socket.create_connection() would
2681 swallow the exception and raise a new one, making it impossible to fetch the
2682 original errno, or to filter timeout errors. Now the original error is
2683 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002689- Updates to the random module:
2690
Georg Brandl27a28582010-10-10 09:49:21 +00002691 * Document which parts of the module are guaranteed to stay the same across
2692 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002694 * Update the seed() method to use all of the bits in a string instead of just
2695 the hash value. This makes better use of the seed value and assures the
2696 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002698 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2699 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2700 which has a slight bias whenever n is not a power of two. Issue #9025.

2723 guaranteed to exist in all Python implementations and the names of hash
2724 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00002829- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2830 now removed, since their effect was inexistent in 3.x (the default encoding is

2853 return characters from the full Unicode range, even on narrow unicode builds
2854 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2855 in Python is that unicodedata.numeric() now returns the correct value for
2856 large code points, and repr() may consider more characters as printable.
2857
Victor Stinner6c00c142010-08-17 23:37:11 +00002858- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002893- Issue #9416: Fix some issues with complex formatting where the output with no
2894 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002895
2896 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003236- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003237 start byte and the continuation byte(s) are now considered invalid, instead of
3238 the number of bytes specified by the start byte. E.g.:
3239 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3240 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3241 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3242 returned a single u'\ufffd'.

3245 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3257 dealing with unary minus applied to a constant. The removed code was mutating
3258 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003262 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003263 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003264
Victor Stinner25e8ec42010-06-25 00:02:38 +00003265- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3266 "w*" format instead. Add tests for "w*" format.
3267
Victor Stinner06e49dd2010-06-13 18:21:50 +00003268- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"

Victor Stinner06e49dd2010-06-13 18:21:50 +00003270 string formats.
3271
Georg Brandl62069d32010-07-31 08:56:11 +00003272- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003273 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3274 location of the raised exception.
3275
Victor Stinner313a1202010-06-11 23:56:51 +00003276- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3277 filenames and enable os.fsencode().
3278
Benjamin Peterson285a6892010-06-22 19:21:52 +00003279- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3280
Georg Brandl62069d32010-07-31 08:56:11 +00003281- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3282 interpreter with characters outside the Basic Multilingual Plane (higher than
3283 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003284
Georg Brandl62069d32010-07-31 08:56:11 +00003285- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3286 TypeError instead of giving a DeprecationWarning when a float is parsed using
3287 the 'L' code (for long long). (All other integer codes already raise
3288 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003289
Victor Stinner600d3be2010-06-10 12:00:55 +00003290- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3291 enable shortcuts for upper case encoding name. Add also a shortcut for
3292 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3293
Georg Brandl62069d32010-07-31 08:56:11 +00003294- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3295 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003296
3297- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003298 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003299 like bytearray.
3300
Georg Brandl62069d32010-07-31 08:56:11 +00003301- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003302 used anymore and it was never documented.
3303
Georg Brandl62069d32010-07-31 08:56:11 +00003304- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003305
Georg Brandl62069d32010-07-31 08:56:11 +00003306- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3307 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003308
Georg Brandl62069d32010-07-31 08:56:11 +00003309- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3310 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3311 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3312 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003313
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003314- Issue #8748: Fix two issues with comparisons between complex and integer
3315 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003316 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3317 (2) The comparison raised an OverflowError for large integers, leading to
3318 unpredictable exceptions when combining integers and complex objects in sets
3319 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003320
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003321- Issue #8766: Initialize _warnings module before importing the first module.
3322 Fix a crash if an empty directory called "encodings" exists in sys.path.
3323
Victor Stinner9ca9c252010-05-19 16:53:30 +00003324- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003325 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003326 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003327
Georg Brandl62069d32010-07-31 08:56:11 +00003328- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3329 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003330
Victor Stinnerae6265f2010-05-15 16:27:27 +00003331- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3332 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003333 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003334 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003335
Victor Stinner59e62db2010-05-15 13:14:32 +00003336- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003337 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003338
Victor Stinnerb744ba12010-05-15 12:27:16 +00003339- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003340 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003341 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3342
Victor Stinner0964ee12010-04-30 16:48:45 +00003343- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003344 PyUnicode_FromString() to support surrogates in the filename and use the right
3345 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003346
Georg Brandl8569e582010-05-19 20:57:08 +00003347- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3348
Georg Brandl62069d32010-07-31 08:56:11 +00003349- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003350
Benjamin Petersonfb886362010-04-24 18:21:17 +00003351- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3352 arguments.
3353
Victor Stinner14284c22010-04-23 12:02:30 +00003354- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003355 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003398- Issue #7845: Rich comparison methods on the complex type now return
3399 NotImplemented rather than raising a TypeError when comparing with an
3400 incompatible type; this allows user-defined classes to implement their own

Antoine Pitroufc8d6f42010-01-17 12:38:54 +00003447
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003448- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003449 where the right hand operand is a set of constants, by turning the set into a
3450 frozenset and pre-building it as a constant. The comparison operation is made
3451 against the constant instead of building a new set each time it is executed (a
3452 similar optimization already existed which turned a list of constants into a
3453 pre-built tuple). Patch and additional tests by Dave Malcolm.

3460 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3461 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3462 parsing certain long numeric strings corresponding to subnormal values, (3) a
3463 memory leak for some values large enough to cause overflow, and (4) a number
3464 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003478- Issue #1811: improve accuracy and cross-platform consistency for true division
3479 of integers: the result of a/b is now correctly rounded for ints a and b (at
3480 least on IEEE 754 platforms), and in particular does not depend on the
3481 internal representation of an int.
Mark Dickinsoncbb62742009-12-27 15:09:50 +00003482
Ronald Oussoren6f6c5622009-12-24 14:03:19 +00003483- Issue #6834: replace the implementation for the 'python' and 'pythonw'

3485
Georg Brandl62069d32010-07-31 08:56:11 +00003486 These executables now work properly with the arch(1) command: ``arch -ppc

3506
Georg Brandl62069d32010-07-31 08:56:11 +00003507- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
3508 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
3509 long but the length of the range did not. Also fix several cases where
3510 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
3511 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003621- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3622 variable argument list. `Py_VA_COPY` is equivalent to C99
3623 `va_copy`, but available on all python platforms.
3624
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003625- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3626 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3627 "step = -step" when reversing a slice.
3628
Georg Brandl62069d32010-07-31 08:56:11 +00003629- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
3630 interpreter to set sys.argv without also modifying sys.path. This helps fix
3631 `CVE-2008-5983
Antoine Pitrouf978fac2010-05-21 17:25:34 +00003632 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
3633
Benjamin Petersonfb886362010-04-24 18:21:17 +00003634- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
3635 strings in an efficient manner.
3636
Antoine Pitrou8689a102010-04-01 16:53:15 +00003637- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003638 function declaration, which was kept for backwards compatibility reasons, is
3639 now removed (the macro was introduced in 1997!).
Antoine Pitrou8689a102010-04-01 16:53:15 +00003640
Georg Brandl62069d32010-07-31 08:56:11 +00003641- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to

Mark Dickinsonde604012010-01-01 19:27:32 +00003647- Issue #5080: The argument parsing functions PyArg_ParseTuple,
Georg Brandl62069d32010-07-31 08:56:11 +00003648 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
3649 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3650 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003651 to match the behaviour of the other integer format codes.
3652
Georg Brandl62069d32010-07-31 08:56:11 +00003653- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00003661- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3662 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3663 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00003664

3676 ``const char *`` as the string is stored beyond the call.
3677
Georg Brandl62069d32010-07-31 08:56:11 +00003678- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3679 allocator will be automatically disabled when running under Valgrind. This
3680 gives improved memory leak detection when running under Valgrind, while taking
3681 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003754- The default size of the re module's compiled regular expression cache has been
3755 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003756 simply clearing the entire cache on overflow to forgetting the least recently
3757 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003758 applications that use a lot of regular expressions and limits the impact of
3759 the performance hit anytime the cache is exceeded.

3772 module is renamed to `_datetime` and if available, overrides all classes
3773 defined in datetime with fast C impementation. Python implementation is based
3774 on the original python prototype for the datetime module by Tim Peters with
3775 minor modifications by the PyPy project. The test suite now tests `datetime`
3776 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004131- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004132 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004133 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004157- Add functools.total_ordering() and functools.cmp_to_key().
4158
Georg Brandl62069d32010-07-31 08:56:11 +00004159- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00004168- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4169 InvalidOperation instead of returning False. (Comparisons involving a quiet
4170 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4171 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004173- Issue #2531: Comparison operations between floats and Decimal instances now
4174 return a result based on the numeric values of the operands; previously they
4175 returned an arbitrary result based on the relative ordering of id(float) and
4176 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4177 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004178
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004179- Added a subtract() method to collections.Counter().
4180
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004181- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004182 argument `-` which tells it to read files to compile from stdin. Each line is
4183 read on demand and the named file is compiled immediately. (Original patch by
4184 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004186- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

4191 Fractions instance now raise TypeError instead of returning True/False. This
4192 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4193 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004236- The internals of the subprocess module on POSIX systems have been replaced by
4237 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4238 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004239
Georg Brandl62069d32010-07-31 08:56:11 +00004240- subprocess.Popen now has restore_signals and start_new_session features. The
4241 default of restore_signals=True is a new behavior compared to earlier Python
4242 versions. This means that signals such as SIGPIPE are not ignored by default
4243 in subprocesses launched by Python (Issue #1652).

4330 position when calling `truncate()`. It would previously change the file
4331 position to the given argument, which goes against the tradition of

4336 archive. The new implementation is significantly faster and can be wrapped in
4337 a :class:`io.BufferedReader` object for more speedups. It also solves an
4338 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00004541- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
4542 from stdin so that existing input does not confuse it and lead to incorrect
4543 entry or an IOError. It also properly flushes it afterwards to avoid the
4544 terminal echoing the input afterwards on OSes such as Solaris.

5385Core and Builtins
5386-----------------
5387
Mark Dickinson865e01a2009-05-07 16:37:01 +00005388- Issue #5914: Add new C API function PyOS_string_to_double, and
5389 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5390
Eric Smith741191f2009-05-06 13:08:15 +00005391- Issue #3382: float.__format__, complex.__format__, and %-formatting
5392 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5393 affects nan -> NAN and inf -> INF.
5394
Mark Hammond5a607a32009-05-06 08:04:54 +00005395- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5396 in all operations, including splitdrive, split, etc. splitunc() now issues
5397 a PendingDeprecation warning.
5398
Eric Smith63376222009-05-05 14:04:18 +00005399- Issue #5920: For float.__format__, change the behavior with the
5400 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5401 to be like 'g' but with at least one decimal point and with a
5402 default precision of 12. Previously, the behavior the same but with
5403 a default precision of 6. This more closely matches str(), and
5404 reduces surprises when adding alignment flags to the empty
5405 presentation type. This also affects the new complex.__format__ in
5406 the same way.
5407
Martin v. Löwis011e8422009-05-05 04:43:17 +00005408- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5409
R. David Murrayb18500d2009-05-04 22:59:07 +00005410- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5411 shadowed by classtype's, even if it was None. property now
5412 inserts the __doc__ into the subclass instance __dict__.
5413
Antoine Pitrou244651a2009-05-04 18:56:13 +00005414- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5415 sequences. Patch by Nick Barnes and Victor Stinner.
5416
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005417- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005418
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005419- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5420 received a new method, detach(). detach() disconnects the underlying stream
5421 from the buffer or text IO and returns it.
5422
Mark Dickinson33841c32009-05-01 15:37:04 +00005423- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5424 floats with absolute value over 1e50. Also remove length
5425 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5426 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005427
Eric Smith741191f2009-05-06 13:08:15 +00005428- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005429 format(complex(1, 2./3), '.5') now produces a sensible result.
5430
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005431- Issue #5864: Fix empty format code formatting for floats so that it
5432 never gives more than the requested number of significant digits.
5433
Eric Smith6dc46f52009-04-27 20:39:49 +00005434- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5435 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5436
Eric Smithcc32a112009-04-26 21:35:14 +00005437- Issue #5835: Deprecate PyOS_ascii_formatd.
5438
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005439- Issue #4971: Fix titlecase for characters that are their own
5440 titlecase, but not their own uppercase.
5441
Benjamin Peterson193152c2009-04-25 01:08:45 +00005442- Issue #5283: Setting __class__ in __del__ caused a segfault.
5443
Mark Dickinsonad476da2009-04-23 19:14:16 +00005444- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5445 z involves nans, infs or negative zeros.
5446
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005447- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005448
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005449- Issue #1869 (and many duplicates): make round(x, n) correctly
5450 rounded for a float x, by using the decimal <-> binary conversions
5451 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5452 consistently agrees with format(x, '.2f').
5453
Benjamin Petersonae937c02009-04-18 20:54:08 +00005454- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5455 some builtin types.
5456
Eric Smith0923d1d2009-04-16 20:16:10 +00005457- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5458
Eric Smith35e84722009-04-16 20:21:28 +00005459- Issue #5515: str.format() type 'n' combined with commas and leading
5460 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005461
5462- Implement PEP 378, Format Specifier for Thousands Separator, for
5463 floats.
5464
Mark Dickinson3370cce2009-04-17 22:40:53 +00005465- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005466 1e11, not 1e12. This avoids printing 13 significant digits in
5467 situations where only 12 of them are correct. Example problem
5468 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5469 long time.)
5470
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005471- Issue #1580: On most platforms, use a 'short' float repr: for a
5472 finite float x, repr(x) now outputs a string based on the shortest
5473 sequence of decimal digits that rounds to x. Previous behaviour was
5474 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005475 Another minor difference is that the new repr switches to
5476 exponential notation at 1e16 instead of the previous 1e17; this
5477 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005478
5479 There's a new sys attribute sys.float_repr_style, which takes
5480 the value 'short' to indicate that we're using short float repr,
5481 and 'legacy' if the short float repr isn't available for one
5482 reason or another.
5483
5484 The float repr change involves incorporating David Gay's 'perfect
5485 rounding' code into the Python core (it's in Python/dtoa.c). As a
5486 secondary consequence, all string-to-float and float-to-string
5487 conversions (including all float formatting operations) will be
5488 correctly rounded on these platforms.
5489
Georg Brandl5f90d792010-08-01 22:31:05 +00005490 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005491 this change does not apply.
5492
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005493- Issue #5759: float() didn't call __float__ on str subclasses.
5494
Georg Brandlabc38772009-04-12 15:51:51 +00005495- The string.maketrans() function is deprecated; there is a new static method
5496 maketrans() on the bytes and bytearray classes. This removes confusion about
5497 the types string.maketrans() is supposed to work with, and mirrors the
5498 methods available on the str class.
5499
R. David Murraydc6da8a2009-04-09 22:16:43 +00005500- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5501 its clarity and its speed.
5502
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005503- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005504 to avoid compiler warnings.
5505
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005506- Issue #3739: The unicode-internal encoder now reports the number of characters
5507 consumed like any other encoder (instead of the number of bytes).

5860 and stderr streams have line-by-line buffering enabled (the default being
5861 to buffer arbitrary chunks of data).
5862
Raymond Hettinger35631532009-01-09 03:58:09 +00005863- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5864 instead of ints (reducing its size from 4 to 8 times thereby reducing
5865 Python's overall memory).
5866
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005867- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5868 an existing .py counterpart, override the co_filename attributes of all
5869 code objects if the original filename is obsolete (which can happen if the
5870 file has been renamed, moved, or if it is accessed through different paths).
5871 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5872
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005873- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5874 one byte. Also fixes the meaning of len() so that it returns the number of
5875 items, rather than the size in bytes.
5876

Georg Brandlccc47b62008-12-28 11:44:14 +00005891- Issue #4759: None is now allowed as the first argument of

5893

5919 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

5921 (on average) per allocation of a bytes instance.
5922
Christian Heimesa872de52008-12-05 08:26:55 +00005923- Issue #4533: File read operation was dreadfully slow due to a slowly

5925 Python 2.x.
5926
Antoine Pitrou5504e892008-12-06 21:27:53 +00005927- Issue #4509: Various issues surrounding resize of bytearray objects to

5929
Georg Brandlf9734072008-12-07 15:30:06 +00005930- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5931 method on file objects with closefd=False. The file descriptor is still
5932 kept open but the file object behaves like a closed file. The ``FileIO``
5933 object also got a new readonly attribute ``closefd``.

5943 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5944 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5945 of using the replace error handler in PyUnicode_DecodeUTF8().

6264
Antoine Pitrou08838b62009-01-21 00:55:13 +00006265- Issue #5008: When a file is opened in append mode with the new IO library,
6266 do an explicit seek to the end of file (so that e.g. tell() returns the
6267 file size rather than 0). This is consistent with the behaviour of the

6298 appropriately when it is being used via socket.makefile() objects
6299 rather than delaying the close by waiting for garbage collection to do it.
6300
