42 timestamp resolution) when checking for freshness of the bytecode.
43
Nick Coghlan1f7ce622012-01-13 21:43:40 +100044- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to

62
Antoine Pitroue0e27352011-12-15 14:31:28 +010063- Fix OSError.__init__ and OSError.__new__ so that each of them can be
64 overriden and take additional arguments (followup to issue #12555).
65
Antoine Pitrou2e872082011-12-15 14:15:31 +010066- Fix the fix for issue #12149: it was incorrect, although it had the side

111
Antoine Pitrou5418ee02011-11-15 01:42:21 +0100112- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder

114
Antoine Pitrou9a812cb2011-11-15 00:00:12 +0100115- Issue #13389: Full garbage collection passes now clear the freelists for
116 list and dict objects. They already cleared other freelists in the
117 interpreter.

Antoine Pitroud42c1d02011-07-23 21:50:21 +02001033 a read1() method), and add a *write_through* parameter to mandate

Ned Deily657b2de2011-06-28 19:51:30 -07001147- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1148 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1149 interpreter process. This could cause failures in non-Distutils subprocesses
1150 and was unreliable since tests or user programs could modify the interpreter
1151 environment after Distutils set it. Instead, have Distutils set the the
1152 deployment target only in the environment of each build subprocess. It is
1153 still possible to globally override the default by setting
1154 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1155 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001156 was built. Also, implement the same handling in packaging.

Nadeem Vawda3c01d162011-08-01 23:48:26 +02001956- Issue #11651: Improve the Makefile test targets to run more of the test suite
1957 more quickly. The --multiprocess option is now enabled by default, reducing
1958 the amount of time needed to run the tests. "make test" and "make quicktest"
1959 now include some resource-intensive tests, but no longer run the test suite
1960 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02001961 an easy platform-independent way to run test suite with sensible defaults.

1970 with the ``-m`` (or ``--match``) option. This works with all test cases

Victor Stinnerf933e1a2010-10-20 22:58:25 +00003087 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00003088 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00003089 encoding and to encode command line arguments on this OS.

3092 filenames encoded to the filesystem encoding with the surrogateescape error

3094
Benjamin Peterson230b2062010-10-16 03:45:45 +00003095- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl27a28582010-10-10 09:49:21 +00003483- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3484 with a non-empty format string. This is an effort to future-proof user
3485 code. If a derived class does not currently implement __format__ but later
3486 adds its own __format__, it would most likely break user code that had
3487 supplied a format string. This will be changed to a DeprecationWaring in
3488 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003490- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3491 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3492 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 +00003494- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3495 functions from the libc caused the methods .upper() and lower() to become
3496 locale aware and created subtly wrong results.
3497
Georg Brandl27a28582010-10-10 09:49:21 +00003498- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3499 non-ASCII byte in the format string.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003501- Issue #4617: Previously it was illegal to delete a name from the local
3502 namespace if it occurs as a free variable in a nested block. This limitation
3503 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3504
Georg Brandl27a28582010-10-10 09:49:21 +00003505- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3506 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3507 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3508 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003510- Issue #9757: memoryview objects get a release() method to release the
3511 underlying buffer (previously this was only done when deallocating the
3512 memoryview), and gain support for the context management protocol.
3513
Antoine Pitrou079ce542010-09-08 12:37:10 +00003514- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003543- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003544 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003545 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003546 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003571 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003653- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003654 it possible for the user to create self-referencing ordered dictionaries which
3655 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003656 approach of using weakref proxies so that reference cycles never get created
3657 in the first place.

3665 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003682- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3683 still return the id of the parent process after it has exited. This process
3684 id may even have been reused by another unrelated process.
3685
Georg Brandl27a28582010-10-10 09:49:21 +00003686- Issue #9792: In case of connection failure, socket.create_connection() would

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003695- Updates to the random module:
3696
Georg Brandl27a28582010-10-10 09:49:21 +00003697 * Document which parts of the module are guaranteed to stay the same across
3698 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003699
Georg Brandl27a28582010-10-10 09:49:21 +00003700 * Update the seed() method to use all of the bits in a string instead of just
3701 the hash value. This makes better use of the seed value and assures the
3702 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003703
Georg Brandl27a28582010-10-10 09:49:21 +00003704 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3705 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3706 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003707
3708 * Improved documentation of arguments to randrange(). Issue #9379.

3859 return characters from the full Unicode range, even on narrow unicode builds
3860 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3861 in Python is that unicodedata.numeric() now returns the correct value for
3862 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00003899- Issue #9416: Fix some issues with complex formatting where the output with no
3900 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003901
3902 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3903 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

4241
Ezio Melotti57221d02010-07-01 07:32:02 +00004242- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004243 start byte and the continuation byte(s) are now considered invalid, instead of
4244 the number of bytes specified by the start byte. E.g.:
4245 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4246 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4247 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4248 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00004250- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
4251 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00004262- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
4263 dealing with unary minus applied to a constant. The removed code was mutating
4264 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00004265
Victor Stinner554f3f02010-06-16 23:33:54 +00004266- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00004267 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00004268 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004269 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00004270
Victor Stinner25e8ec42010-06-25 00:02:38 +00004271- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
4272 "w*" format instead. Add tests for "w*" format.
4273
Victor Stinner06e49dd2010-06-13 18:21:50 +00004274- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00004275 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00004276 string formats.
4277
Georg Brandl62069d32010-07-31 08:56:11 +00004278- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004279 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4280 location of the raised exception.
4281
Victor Stinner313a1202010-06-11 23:56:51 +00004282- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4283 filenames and enable os.fsencode().
4284
Benjamin Peterson285a6892010-06-22 19:21:52 +00004285- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
4286
Georg Brandl62069d32010-07-31 08:56:11 +00004287- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
4288 interpreter with characters outside the Basic Multilingual Plane (higher than
4289 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00004290
Georg Brandl62069d32010-07-31 08:56:11 +00004291- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4292 TypeError instead of giving a DeprecationWarning when a float is parsed using
4293 the 'L' code (for long long). (All other integer codes already raise
4294 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004295
Victor Stinner600d3be2010-06-10 12:00:55 +00004296- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4297 enable shortcuts for upper case encoding name. Add also a shortcut for
4298 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4299
Georg Brandl62069d32010-07-31 08:56:11 +00004300- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4301 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004302
4303- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004304 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004305 like bytearray.
4306
Georg Brandl62069d32010-07-31 08:56:11 +00004307- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004308 used anymore and it was never documented.
4309
Georg Brandl62069d32010-07-31 08:56:11 +00004310- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00004311
Georg Brandl62069d32010-07-31 08:56:11 +00004312- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4313 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004314
Georg Brandl62069d32010-07-31 08:56:11 +00004315- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4316 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4317 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4318 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004319
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004320- Issue #8748: Fix two issues with comparisons between complex and integer
4321 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004322 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4323 (2) The comparison raised an OverflowError for large integers, leading to
4324 unpredictable exceptions when combining integers and complex objects in sets
4325 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004326
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004327- Issue #8766: Initialize _warnings module before importing the first module.
4328 Fix a crash if an empty directory called "encodings" exists in sys.path.
4329
Victor Stinner9ca9c252010-05-19 16:53:30 +00004330- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004331 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004332 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004333
Georg Brandl62069d32010-07-31 08:56:11 +00004334- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4335 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004336
Victor Stinnerae6265f2010-05-15 16:27:27 +00004337- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4338 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004339 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004340 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004341
Victor Stinner59e62db2010-05-15 13:14:32 +00004342- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004343 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004344
Victor Stinnerb744ba12010-05-15 12:27:16 +00004345- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004346 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004347 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4348
Victor Stinner0964ee12010-04-30 16:48:45 +00004349- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004350 PyUnicode_FromString() to support surrogates in the filename and use the right
4351 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004352
Georg Brandl8569e582010-05-19 20:57:08 +00004353- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4354
Georg Brandl62069d32010-07-31 08:56:11 +00004355- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004356
Benjamin Petersonfb886362010-04-24 18:21:17 +00004357- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4358 arguments.
4359
Victor Stinner14284c22010-04-23 12:02:30 +00004360- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004361 indirectly Python signal handlers anymore because mywrite() ignores exceptions
4362 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00004363
Victor Stinner31be90b2010-04-22 19:38:16 +00004364- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00004366
Georg Brandl62069d32010-07-31 08:56:11 +00004367- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4368 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004369
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004370- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004371 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
4372 compared to the dynamic memory allocation fallback. Patch by Charles-François

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00004454- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00004455 where the right hand operand is a set of constants, by turning the set into a
4456 frozenset and pre-building it as a constant. The comparison operation is made
4457 against the constant instead of building a new set each time it is executed (a
4458 similar optimization already existed which turned a list of constants into a
4459 pre-built tuple). Patch and additional tests by Dave Malcolm.

4486 least on IEEE 754 platforms), and in particular does not depend on the
4487 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00004760- The default size of the re module's compiled regular expression cache has been
4761 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004762 simply clearing the entire cache on overflow to forgetting the least recently
4763 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004764 applications that use a lot of regular expressions and limits the impact of
4765 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004777- Issue #7989: Added pure python implementation of the `datetime` module. The C
4778 module is renamed to `_datetime` and if available, overrides all classes
4779 defined in datetime with fast C impementation. Python implementation is based
4780 on the original python prototype for the datetime module by Tim Peters with
4781 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00005137- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00005138 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00005139 relies on the system threading library, so as to avoid a semi-busy wait loop.

5164
Georg Brandl62069d32010-07-31 08:56:11 +00005165- Issue #8257: The Decimal construct now accepts a float instance directly,
5166 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00005167
5168 >>> Decimal(1.1)

Georg Brandl62069d32010-07-31 08:56:11 +00005174- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5175 InvalidOperation instead of returning False. (Comparisons involving a quiet
5176 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5177 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00005179- Issue #2531: Comparison operations between floats and Decimal instances now
5180 return a result based on the numeric values of the operands; previously they
5181 returned an arbitrary result based on the relative ordering of id(float) and
5182 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
5183 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00005184
Raymond Hettinger9c01e442010-04-03 10:32:58 +00005185- Added a subtract() method to collections.Counter().
5186
Barry Warsawd5f9bf52010-03-31 21:36:22 +00005187- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005188 argument `-` which tells it to read files to compile from stdin. Each line is
5189 read on demand and the named file is compiled immediately. (Original patch by
5190 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00005192- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00005196- Comparisons using one of <, <=, >, >= between a complex instance and a
5197 Fractions instance now raise TypeError instead of returning True/False. This
5198 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5199 <=> complex, and complex <=> complex comparisons.

5207
Antoine Pitrou910bd512010-03-22 20:11:09 +00005208- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00005209 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00005242- The internals of the subprocess module on POSIX systems have been replaced by
5243 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5244 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00005245
Georg Brandl62069d32010-07-31 08:56:11 +00005246- subprocess.Popen now has restore_signals and start_new_session features. The
5247 default of restore_signals=True is a new behavior compared to earlier Python
5248 versions. This means that signals such as SIGPIPE are not ignored by default
5249 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00005335- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
5336 position when calling `truncate()`. It would previously change the file
5337 position to the given argument, which goes against the tradition of

5342 archive. The new implementation is significantly faster and can be wrapped in
5343 a :class:`io.BufferedReader` object for more speedups. It also solves an
5344 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005742- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005743 compared to other unix systems. In particular, os.getgroups() does not reflect

Antoine Pitroue4501852009-05-14 18:55:55 +00006338- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6339 library. This means, for example, that opening an UTF-16 text file in
6340 append mode doesn't add a BOM at the end of the file if the file isn't
6341 empty.

6391Core and Builtins
6392-----------------
6393
Mark Dickinson865e01a2009-05-07 16:37:01 +00006394- Issue #5914: Add new C API function PyOS_string_to_double, and
6395 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6396
Eric Smith741191f2009-05-06 13:08:15 +00006397- Issue #3382: float.__format__, complex.__format__, and %-formatting
6398 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6399 affects nan -> NAN and inf -> INF.
6400
Mark Hammond5a607a32009-05-06 08:04:54 +00006401- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6402 in all operations, including splitdrive, split, etc. splitunc() now issues
6403 a PendingDeprecation warning.
6404
Eric Smith63376222009-05-05 14:04:18 +00006405- Issue #5920: For float.__format__, change the behavior with the
6406 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6407 to be like 'g' but with at least one decimal point and with a
6408 default precision of 12. Previously, the behavior the same but with
6409 a default precision of 6. This more closely matches str(), and
6410 reduces surprises when adding alignment flags to the empty
6411 presentation type. This also affects the new complex.__format__ in
6412 the same way.
6413
Martin v. Löwis011e8422009-05-05 04:43:17 +00006414- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6415
R. David Murrayb18500d2009-05-04 22:59:07 +00006416- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6417 shadowed by classtype's, even if it was None. property now
6418 inserts the __doc__ into the subclass instance __dict__.
6419
Antoine Pitrou244651a2009-05-04 18:56:13 +00006420- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6421 sequences. Patch by Nick Barnes and Victor Stinner.
6422
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006423- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006424
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006425- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6426 received a new method, detach(). detach() disconnects the underlying stream
6427 from the buffer or text IO and returns it.
6428
Mark Dickinson33841c32009-05-01 15:37:04 +00006429- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6430 floats with absolute value over 1e50. Also remove length
6431 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6432 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006433
Eric Smith741191f2009-05-06 13:08:15 +00006434- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006435 format(complex(1, 2./3), '.5') now produces a sensible result.
6436
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006437- Issue #5864: Fix empty format code formatting for floats so that it
6438 never gives more than the requested number of significant digits.
6439
Eric Smith6dc46f52009-04-27 20:39:49 +00006440- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6441 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6442
Eric Smithcc32a112009-04-26 21:35:14 +00006443- Issue #5835: Deprecate PyOS_ascii_formatd.
6444
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006445- Issue #4971: Fix titlecase for characters that are their own
6446 titlecase, but not their own uppercase.
6447
Benjamin Peterson193152c2009-04-25 01:08:45 +00006448- Issue #5283: Setting __class__ in __del__ caused a segfault.
6449
Mark Dickinsonad476da2009-04-23 19:14:16 +00006450- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6451 z involves nans, infs or negative zeros.
6452
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006453- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006454
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006455- Issue #1869 (and many duplicates): make round(x, n) correctly
6456 rounded for a float x, by using the decimal <-> binary conversions
6457 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6458 consistently agrees with format(x, '.2f').
6459
Benjamin Petersonae937c02009-04-18 20:54:08 +00006460- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6461 some builtin types.
6462
Eric Smith0923d1d2009-04-16 20:16:10 +00006463- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6464
Eric Smith35e84722009-04-16 20:21:28 +00006465- Issue #5515: str.format() type 'n' combined with commas and leading
6466 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006467
6468- Implement PEP 378, Format Specifier for Thousands Separator, for
6469 floats.
6470
Mark Dickinson3370cce2009-04-17 22:40:53 +00006471- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006472 1e11, not 1e12. This avoids printing 13 significant digits in
6473 situations where only 12 of them are correct. Example problem
6474 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6475 long time.)
6476
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006477- Issue #1580: On most platforms, use a 'short' float repr: for a
6478 finite float x, repr(x) now outputs a string based on the shortest
6479 sequence of decimal digits that rounds to x. Previous behaviour was
6480 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006481 Another minor difference is that the new repr switches to
6482 exponential notation at 1e16 instead of the previous 1e17; this
6483 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006484
6485 There's a new sys attribute sys.float_repr_style, which takes
6486 the value 'short' to indicate that we're using short float repr,
6487 and 'legacy' if the short float repr isn't available for one
6488 reason or another.
6489
6490 The float repr change involves incorporating David Gay's 'perfect
6491 rounding' code into the Python core (it's in Python/dtoa.c). As a
6492 secondary consequence, all string-to-float and float-to-string
6493 conversions (including all float formatting operations) will be
6494 correctly rounded on these platforms.
6495
Georg Brandl5f90d792010-08-01 22:31:05 +00006496 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006497 this change does not apply.
6498
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006499- Issue #5759: float() didn't call __float__ on str subclasses.
6500
Georg Brandlabc38772009-04-12 15:51:51 +00006501- The string.maketrans() function is deprecated; there is a new static method
6502 maketrans() on the bytes and bytearray classes. This removes confusion about
6503 the types string.maketrans() is supposed to work with, and mirrors the
6504 methods available on the str class.
6505
R. David Murraydc6da8a2009-04-09 22:16:43 +00006506- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6507 its clarity and its speed.
6508
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006509- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006510 to avoid compiler warnings.
6511
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006512- Issue #3739: The unicode-internal encoder now reports the number of characters
6513 consumed like any other encoder (instead of the number of bytes).

6657
Brett Cannon0759dd62009-04-01 18:13:07 +00006658- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
6659
Georg Brandlab6f2f62009-03-31 04:16:10 +00006660- Fix a segfault when running test_exceptions with coverage, caused by
6661 insufficient checks in accessors of Exception.__context__.
6662
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006663- Issue #5604: non-ASCII characters in module name passed to
6664 imp.find_module() were converted to UTF-8 while the path is
6665 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00006667- Issue #5126: str.isprintable() returned False for space characters.
6668
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006669- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6670 the end sys.path, for compatibility with the system install of Python.
6671
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006672- Issue #4688: Add a heuristic so that tuples and dicts containing only
6673 untrackable objects are not tracked by the garbage collector. This can
6674 reduce the size of collections and therefore the garbage collection overhead
6675 on long-running programs, depending on their particular use of datatypes.
6676
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006677- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

6689 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6690 and sizeof(Py_UNICODE) == 2.
6691
Eric Smith8ec90442009-03-14 12:29:34 +00006692- Issue #5237: Allow auto-numbered fields in str.format(). For

6694
Antoine Pitrou652e7072009-03-13 19:25:20 +00006695- Issue #5392: when a very low recursion limit was set, the interpreter would
6696 abort with a fatal error after the recursion limit was hit twice.
6697
Matthias Klose042f1332009-04-04 14:32:42 +00006698- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

6744
Lars Gustäbel42e00912009-03-22 20:34:29 +00006745- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6746 forever on incomplete input. That caused tarfile.open() to hang when used
6747 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6748 partial bzip2 compressed data.
6749
Mark Dickinson79f52032009-03-17 23:12:51 +00006750- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00006798- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6799 it now forces its argument to double before testing for infinity.
6800
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006801- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6802 returns a non-number type.
6803
Benjamin Peterson87618552009-02-08 15:00:52 +00006804- Issue #5182: Removed memoryview.__str__.

6818 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6819 evaluation loop is compiled with a new dispatch mechanism which gives
6820 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006835- Issue #4935: The overflow checking code in the expandtabs() method common
6836 to str, bytes and bytearray could be optimized away by the compiler, letting
6837 the interpreter segfault instead of raising an error.
6838
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006839- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006861 having been closed (for instance, a read() call could return some
6862 previously buffered data). Patch by Dmitry Vasiliev.
6863
Antoine Pitrou05608432009-01-09 18:53:14 +00006864- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6865 flag to work properly. Furthermore, when specifying -u, the text stdout
6866 and stderr streams have line-by-line buffering enabled (the default being
6867 to buffer arbitrary chunks of data).
6868
Raymond Hettinger35631532009-01-09 03:58:09 +00006869- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6870 instead of ints (reducing its size from 4 to 8 times thereby reducing
6871 Python's overall memory).
6872
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006873- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6874 an existing .py counterpart, override the co_filename attributes of all
6875 code objects if the original filename is obsolete (which can happen if the
6876 file has been renamed, moved, or if it is accessed through different paths).
6877 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6878
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006879- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6880 one byte. Also fixes the meaning of len() so that it returns the number of
6881 items, rather than the size in bytes.
6882
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006883- Issue #4075: Use OutputDebugStringW in Py_FatalError.

6895 where the tp_hash and tp_dict slots are both NULL.
6896
Georg Brandlccc47b62008-12-28 11:44:14 +00006897- Issue #4759: None is now allowed as the first argument of
6898 bytearray.translate(). It was always allowed for bytes.translate().
6899

6949 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

6951 of using the replace error handler in PyUnicode_DecodeUTF8().

7270
Antoine Pitrou08838b62009-01-21 00:55:13 +00007271- Issue #5008: When a file is opened in append mode with the new IO library,
7272 do an explicit seek to the end of file (so that e.g. tell() returns the
7273 file size rather than 0). This is consistent with the behaviour of the

7304 appropriately when it is being used via socket.makefile() objects
7305 rather than delaying the close by waiting for garbage collection to do it.
7306
Raymond Hettingerb8baf632009-01-14 02:20:07 +00007307- Issue #1696199: Add collections.Counter() for rapid and convenient
