Ned Deily657b2de2011-06-28 19:51:30 -0700262- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
263 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
264 interpreter process. This could cause failures in non-Distutils subprocesses
265 and was unreliable since tests or user programs could modify the interpreter
266 environment after Distutils set it. Instead, have Distutils set the the
267 deployment target only in the environment of each build subprocess. It is
268 still possible to globally override the default by setting
269 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
270 greater or equal to the default value, the value with which the interpreter
271 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001766- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1767 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001768 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001769 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001770 encoding and to encode command line arguments on this OS.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002149- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2150 threads are still running. Instead, reinitialize the GIL on a second call to
2151 Py_Initialize().
2152
Georg Brandl27a28582010-10-10 09:49:21 +00002153- All SyntaxErrors now have a column offset and therefore a caret when the error
2154 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00002156- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

Nick Coghlan37ee8502010-12-03 14:26:13 +00002159- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002162- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2163 with a non-empty format string. This is an effort to future-proof user
2164 code. If a derived class does not currently implement __format__ but later
2165 adds its own __format__, it would most likely break user code that had
2166 supplied a format string. This will be changed to a DeprecationWaring in
2167 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002169- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2170 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2171 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 +00002173- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2174 functions from the libc caused the methods .upper() and lower() to become
2175 locale aware and created subtly wrong results.
2176
Georg Brandl27a28582010-10-10 09:49:21 +00002177- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002180- Issue #4617: Previously it was illegal to delete a name from the local
2181 namespace if it occurs as a free variable in a nested block. This limitation
2182 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2183
Georg Brandl27a28582010-10-10 09:49:21 +00002184- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2185 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2186 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2187 single character on UCS-2 builds.

2191 memoryview), and gain support for the context management protocol.
2192
Antoine Pitrou079ce542010-09-08 12:37:10 +00002193- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00002222- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002223 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002224 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002225 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002250 retry the select() loop instead of bailing out. This is because select() can
2251 incorrectly report a socket as ready for reading (for example, if it received
2252 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002332- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002333 it possible for the user to create self-referencing ordered dictionaries which
2334 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002335 approach of using weakref proxies so that reference cycles never get created
2336 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002342- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2343 environment variable to set the filesystem encoding at Python startup.
2344 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2345 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002351- The pprint module now supports printing OrderedDicts in their given order

2359 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002360
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002361- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2362 still return the id of the parent process after it has exited. This process
2363 id may even have been reused by another unrelated process.
2364
Georg Brandl27a28582010-10-10 09:49:21 +00002365- Issue #9792: In case of connection failure, socket.create_connection() would
2366 swallow the exception and raise a new one, making it impossible to fetch the
2367 original errno, or to filter timeout errors. Now the original error is
2368 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002374- Updates to the random module:
2375
Georg Brandl27a28582010-10-10 09:49:21 +00002376 * Document which parts of the module are guaranteed to stay the same across
2377 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002378
Georg Brandl27a28582010-10-10 09:49:21 +00002379 * Update the seed() method to use all of the bits in a string instead of just
2380 the hash value. This makes better use of the seed value and assures the
2381 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002382
Georg Brandl27a28582010-10-10 09:49:21 +00002383 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2384 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2385 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002386
2387 * Improved documentation of arguments to randrange(). Issue #9379.

2538 return characters from the full Unicode range, even on narrow unicode builds
2539 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2540 in Python is that unicodedata.numeric() now returns the correct value for
2541 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002578- Issue #9416: Fix some issues with complex formatting where the output with no
2579 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002580
2581 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

2920
Ezio Melotti57221d02010-07-01 07:32:02 +00002921- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002922 start byte and the continuation byte(s) are now considered invalid, instead of
2923 the number of bytes specified by the start byte. E.g.:
2924 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2925 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2926 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2927 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002929- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2930 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

2942 dealing with unary minus applied to a constant. The removed code was mutating
2943 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00002945- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002946 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002947 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002948 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002949
Victor Stinner25e8ec42010-06-25 00:02:38 +00002950- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2951 "w*" format instead. Add tests for "w*" format.
2952
Victor Stinner06e49dd2010-06-13 18:21:50 +00002953- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002954 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002955 string formats.
2956
Georg Brandl62069d32010-07-31 08:56:11 +00002957- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002958 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2959 location of the raised exception.
2960
Victor Stinner313a1202010-06-11 23:56:51 +00002961- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2962 filenames and enable os.fsencode().
2963
Benjamin Peterson285a6892010-06-22 19:21:52 +00002964- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2965
Georg Brandl62069d32010-07-31 08:56:11 +00002966- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2967 interpreter with characters outside the Basic Multilingual Plane (higher than
2968 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002969
Georg Brandl62069d32010-07-31 08:56:11 +00002970- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2971 TypeError instead of giving a DeprecationWarning when a float is parsed using
2972 the 'L' code (for long long). (All other integer codes already raise
2973 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002974
Victor Stinner600d3be2010-06-10 12:00:55 +00002975- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2976 enable shortcuts for upper case encoding name. Add also a shortcut for
2977 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2978
Georg Brandl62069d32010-07-31 08:56:11 +00002979- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2980 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002981
2982- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002983 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002984 like bytearray.
2985
Georg Brandl62069d32010-07-31 08:56:11 +00002986- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002987 used anymore and it was never documented.
2988
Georg Brandl62069d32010-07-31 08:56:11 +00002989- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002990
Georg Brandl62069d32010-07-31 08:56:11 +00002991- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2992 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002993
Georg Brandl62069d32010-07-31 08:56:11 +00002994- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2995 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2996 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2997 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002998
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002999- Issue #8748: Fix two issues with comparisons between complex and integer
3000 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003001 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3002 (2) The comparison raised an OverflowError for large integers, leading to
3003 unpredictable exceptions when combining integers and complex objects in sets
3004 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003005
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003006- Issue #8766: Initialize _warnings module before importing the first module.
3007 Fix a crash if an empty directory called "encodings" exists in sys.path.
3008
Victor Stinner9ca9c252010-05-19 16:53:30 +00003009- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003010 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003011 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003012
Georg Brandl62069d32010-07-31 08:56:11 +00003013- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3014 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003015
Victor Stinnerae6265f2010-05-15 16:27:27 +00003016- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3017 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003018 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003019 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003020
Victor Stinner59e62db2010-05-15 13:14:32 +00003021- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003022 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003023
Victor Stinnerb744ba12010-05-15 12:27:16 +00003024- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003025 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003026 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3027
Victor Stinner0964ee12010-04-30 16:48:45 +00003028- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003029 PyUnicode_FromString() to support surrogates in the filename and use the right
3030 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003031
Georg Brandl8569e582010-05-19 20:57:08 +00003032- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3033
Georg Brandl62069d32010-07-31 08:56:11 +00003034- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003035
Benjamin Petersonfb886362010-04-24 18:21:17 +00003036- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3037 arguments.
3038
Victor Stinner14284c22010-04-23 12:02:30 +00003039- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003040 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Victor Stinner31be90b2010-04-22 19:38:16 +00003045
Georg Brandl62069d32010-07-31 08:56:11 +00003046- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3047 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003048
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003049- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003050 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

3137 similar optimization already existed which turned a list of constants into a

3442 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003443 applications that use a lot of regular expressions and limits the impact of
3444 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003858- Issue #2531: Comparison operations between floats and Decimal instances now
3859 return a result based on the numeric values of the operands; previously they
3860 returned an arbitrary result based on the relative ordering of id(float) and
3861 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3862 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003866- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003867 argument `-` which tells it to read files to compile from stdin. Each line is
3868 read on demand and the named file is compiled immediately. (Original patch by
3869 Piotr Ożarowski).

3876 Fractions instance now raise TypeError instead of returning True/False. This
3877 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3878 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003921- The internals of the subprocess module on POSIX systems have been replaced by
3922 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3923 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003925- subprocess.Popen now has restore_signals and start_new_session features. The
3926 default of restore_signals=True is a new behavior compared to earlier Python
3927 versions. This means that signals such as SIGPIPE are not ignored by default
3928 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004014- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4015 position when calling `truncate()`. It would previously change the file
4016 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004017 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004019- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004020 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4021 archive. The new implementation is significantly faster and can be wrapped in
4022 a :class:`io.BufferedReader` object for more speedups. It also solves an
4023 issue where interleaved calls to `read()` and `readline()` give wrong results.
4024 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004359- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004360 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4361 PyPycLoader inherit from this class and provide implementations in relation to
4362 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004363
Brett Cannon64ef00f2009-07-20 03:19:18 +00004364- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4365 the documentation said it did even though the code in PyLoader relied on the
4366 abstract method required by ResourceLoader.
4367
Georg Brandl62069d32010-07-31 08:56:11 +00004368- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004421- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004422 compared to other unix systems. In particular, os.getgroups() does not reflect
4423 any changes made using os.setgroups() but basicly always returns the same
4424 information as the id command. os.getgroups() can now return more than 16
4425 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004426

Georg Brandl62069d32010-07-31 08:56:11 +00004450- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4451 Prior to this change, timezone adjustment in utctimetuple() could produce
4452 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4456 directive. When the ``%z`` directive is present in the format string, an
4457 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4458 ``datetime.timezone`` instance constructed from the parsed offset. If both
4459 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4460 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00004463 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4464 ``datetime.timezone``, return fixed name and UTC offset from their
4465 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4466 returns ``None``. A class attribute, ``utc`` contains an instance
4467 representing the UTC timezone. Original patch by Rafe Kaplan.

Antoine Pitrou61f77b52009-05-24 15:46:13 +00004991- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4992 than an int, which makes some operations possible under 64-bit Linux (e.g.
4993 DN_MULTISHOT with F_NOTIFY).
4994
Antoine Pitrou716c4442009-05-23 19:04:03 +00004995- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005001- Issue #1983: Fix functions taking or returning a process identifier to use
5002 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5003 a process identifier type wider than the standard C integer type.
5004

5016
Antoine Pitroue4501852009-05-14 18:55:55 +00005017- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5018 library. This means, for example, that opening an UTF-16 text file in
5019 append mode doesn't add a BOM at the end of the file if the file isn't
5020 empty.
5021
R. David Murray74b89242009-05-13 17:33:03 +00005022- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5023 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5024 corrects a pydoc regression.
5025
Georg Brandl5f90d792010-08-01 22:31:05 +00005026- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005027 now it does. This also means getfp method now returns the real fp.

5070Core and Builtins
5071-----------------
5072
Mark Dickinson865e01a2009-05-07 16:37:01 +00005073- Issue #5914: Add new C API function PyOS_string_to_double, and
5074 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5075
Eric Smith741191f2009-05-06 13:08:15 +00005076- Issue #3382: float.__format__, complex.__format__, and %-formatting
5077 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5078 affects nan -> NAN and inf -> INF.
5079
Mark Hammond5a607a32009-05-06 08:04:54 +00005080- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5081 in all operations, including splitdrive, split, etc. splitunc() now issues
5082 a PendingDeprecation warning.
5083
Eric Smith63376222009-05-05 14:04:18 +00005084- Issue #5920: For float.__format__, change the behavior with the
5085 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5086 to be like 'g' but with at least one decimal point and with a
5087 default precision of 12. Previously, the behavior the same but with
5088 a default precision of 6. This more closely matches str(), and
5089 reduces surprises when adding alignment flags to the empty
5090 presentation type. This also affects the new complex.__format__ in
5091 the same way.
5092
Martin v. Löwis011e8422009-05-05 04:43:17 +00005093- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5094
R. David Murrayb18500d2009-05-04 22:59:07 +00005095- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5096 shadowed by classtype's, even if it was None. property now
5097 inserts the __doc__ into the subclass instance __dict__.
5098
Antoine Pitrou244651a2009-05-04 18:56:13 +00005099- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5100 sequences. Patch by Nick Barnes and Victor Stinner.
5101
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005102- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005103
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005104- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5105 received a new method, detach(). detach() disconnects the underlying stream
5106 from the buffer or text IO and returns it.
5107
Mark Dickinson33841c32009-05-01 15:37:04 +00005108- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5109 floats with absolute value over 1e50. Also remove length
5110 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5111 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005112
Eric Smith741191f2009-05-06 13:08:15 +00005113- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005114 format(complex(1, 2./3), '.5') now produces a sensible result.
5115
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005116- Issue #5864: Fix empty format code formatting for floats so that it
5117 never gives more than the requested number of significant digits.
5118
Eric Smith6dc46f52009-04-27 20:39:49 +00005119- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5120 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5121
Eric Smithcc32a112009-04-26 21:35:14 +00005122- Issue #5835: Deprecate PyOS_ascii_formatd.
5123
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005124- Issue #4971: Fix titlecase for characters that are their own
5125 titlecase, but not their own uppercase.
5126
Benjamin Peterson193152c2009-04-25 01:08:45 +00005127- Issue #5283: Setting __class__ in __del__ caused a segfault.
5128
Mark Dickinsonad476da2009-04-23 19:14:16 +00005129- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5130 z involves nans, infs or negative zeros.
5131
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005132- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005133
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005134- Issue #1869 (and many duplicates): make round(x, n) correctly
5135 rounded for a float x, by using the decimal <-> binary conversions
5136 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5137 consistently agrees with format(x, '.2f').
5138
Benjamin Petersonae937c02009-04-18 20:54:08 +00005139- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5140 some builtin types.
5141
Eric Smith0923d1d2009-04-16 20:16:10 +00005142- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5143
Eric Smith35e84722009-04-16 20:21:28 +00005144- Issue #5515: str.format() type 'n' combined with commas and leading
5145 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005146
5147- Implement PEP 378, Format Specifier for Thousands Separator, for
5148 floats.
5149
Mark Dickinson3370cce2009-04-17 22:40:53 +00005150- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005151 1e11, not 1e12. This avoids printing 13 significant digits in
5152 situations where only 12 of them are correct. Example problem
5153 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5154 long time.)
5155
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005156- Issue #1580: On most platforms, use a 'short' float repr: for a
5157 finite float x, repr(x) now outputs a string based on the shortest
5158 sequence of decimal digits that rounds to x. Previous behaviour was
5159 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005160 Another minor difference is that the new repr switches to
5161 exponential notation at 1e16 instead of the previous 1e17; this
5162 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005163
5164 There's a new sys attribute sys.float_repr_style, which takes
5165 the value 'short' to indicate that we're using short float repr,
5166 and 'legacy' if the short float repr isn't available for one
5167 reason or another.
5168
5169 The float repr change involves incorporating David Gay's 'perfect
5170 rounding' code into the Python core (it's in Python/dtoa.c). As a
5171 secondary consequence, all string-to-float and float-to-string
5172 conversions (including all float formatting operations) will be
5173 correctly rounded on these platforms.
5174
Georg Brandl5f90d792010-08-01 22:31:05 +00005175 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005176 this change does not apply.
5177
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005178- Issue #5759: float() didn't call __float__ on str subclasses.
5179
Georg Brandlabc38772009-04-12 15:51:51 +00005180- The string.maketrans() function is deprecated; there is a new static method
5181 maketrans() on the bytes and bytearray classes. This removes confusion about
5182 the types string.maketrans() is supposed to work with, and mirrors the
5183 methods available on the str class.
5184
R. David Murraydc6da8a2009-04-09 22:16:43 +00005185- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5186 its clarity and its speed.
5187
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005188- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005189 to avoid compiler warnings.
5190
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005191- Issue #3739: The unicode-internal encoder now reports the number of characters
5192 consumed like any other encoder (instead of the number of bytes).

5330
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005331- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5332 byte, and the 'C' code only accepts a unicode character.
5333
Georg Brandl406b3d82009-04-11 21:24:37 +00005334- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5335 when hitting the recursion limit under certain circumstances.
5336
Brett Cannon0759dd62009-04-01 18:13:07 +00005337- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.

5349 the end sys.path, for compatibility with the system install of Python.
5350
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005351- Issue #4688: Add a heuristic so that tuples and dicts containing only
5352 untrackable objects are not tracked by the garbage collector. This can
5353 reduce the size of collections and therefore the garbage collection overhead
5354 on long-running programs, depending on their particular use of datatypes.
5355
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005356- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5369 and sizeof(Py_UNICODE) == 2.
5370
Eric Smith8ec90442009-03-14 12:29:34 +00005371- Issue #5237: Allow auto-numbered fields in str.format(). For

5423
Lars Gustäbel42e00912009-03-22 20:34:29 +00005424- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5425 forever on incomplete input. That caused tarfile.open() to hang when used
5426 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5427 partial bzip2 compressed data.
5428
Mark Dickinson79f52032009-03-17 23:12:51 +00005429- Issue #2110: Add support for thousands separator and 'n' type

5497 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5498 evaluation loop is compiled with a new dispatch mechanism which gives
5499 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8043cf82009-01-09 19:54:29 +00005540 having been closed (for instance, a read() call could return some
5541 previously buffered data). Patch by Dmitry Vasiliev.
5542
Antoine Pitrou05608432009-01-09 18:53:14 +00005543- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5544 flag to work properly. Furthermore, when specifying -u, the text stdout
5545 and stderr streams have line-by-line buffering enabled (the default being
5546 to buffer arbitrary chunks of data).
5547
Raymond Hettinger35631532009-01-09 03:58:09 +00005548- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5549 instead of ints (reducing its size from 4 to 8 times thereby reducing
5550 Python's overall memory).
5551
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005552- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5553 an existing .py counterpart, override the co_filename attributes of all
5554 code objects if the original filename is obsolete (which can happen if the
5555 file has been renamed, moved, or if it is accessed through different paths).
5556 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5557
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005558- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5559 one byte. Also fixes the meaning of len() so that it returns the number of
5560 items, rather than the size in bytes.
5561
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005562- Issue #4075: Use OutputDebugStringW in Py_FatalError.

5949
Antoine Pitrou08838b62009-01-21 00:55:13 +00005950- Issue #5008: When a file is opened in append mode with the new IO library,
5951 do an explicit seek to the end of file (so that e.g. tell() returns the
5952 file size rather than 0). This is consistent with the behaviour of the

5983 appropriately when it is being used via socket.makefile() objects
5984 rather than delaying the close by waiting for garbage collection to do it.
5985
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005986- Issue #1696199: Add collections.Counter() for rapid and convenient
