1199 files in binary mode, using the email package's binary support to parse

1230 keyword-only argument. The preceding positional argument was deprecated,
1231 so it made no sense to add filter as a positional argument.

Armin Ronacher8d96d772011-01-22 13:13:05 +00001258- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1259 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1260 of HTTP 1.1.
1261
Armin Ronacher59531282011-01-22 13:44:22 +00001262- To match the behaviour of HTTP server, the HTTP client library now also
1263 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1264 that for incoming headers which makes this behaviour now consistent in
1265 both incoming and outgoing direction.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002022 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002023 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2417 with a non-empty format string. This is an effort to future-proof user
2418 code. If a derived class does not currently implement __format__ but later
2419 adds its own __format__, it would most likely break user code that had
2420 supplied a format string. This will be changed to a DeprecationWaring in
2421 Python 3.3 and it will be an error in Python 3.4.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002427- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2428 functions from the libc caused the methods .upper() and lower() to become
2429 locale aware and created subtly wrong results.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002434- Issue #4617: Previously it was illegal to delete a name from the local
2435 namespace if it occurs as a free variable in a nested block. This limitation
2436 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2437
Georg Brandl27a28582010-10-10 09:49:21 +00002438- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2439 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2440 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2441 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002476- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002477 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002478 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002479 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002504 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002586- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002587 it possible for the user to create self-referencing ordered dictionaries which
2588 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002589 approach of using weakref proxies so that reference cycles never get created
2590 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002592- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002596- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2597 environment variable to set the filesystem encoding at Python startup.
2598 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2599 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002605- The pprint module now supports printing OrderedDicts in their given order

2613 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002614
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002615- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2616 still return the id of the parent process after it has exited. This process
2617 id may even have been reused by another unrelated process.
2618
Georg Brandl27a28582010-10-10 09:49:21 +00002619- Issue #9792: In case of connection failure, socket.create_connection() would
2620 swallow the exception and raise a new one, making it impossible to fetch the
2621 original errno, or to filter timeout errors. Now the original error is
2622 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002628- Updates to the random module:
2629
Georg Brandl27a28582010-10-10 09:49:21 +00002630 * Document which parts of the module are guaranteed to stay the same across
2631 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002632
Georg Brandl27a28582010-10-10 09:49:21 +00002633 * Update the seed() method to use all of the bits in a string instead of just
2634 the hash value. This makes better use of the seed value and assures the
2635 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002636
Georg Brandl27a28582010-10-10 09:49:21 +00002637 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2638 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2639 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002640
2641 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002660- hashlib has two new constant attributes: algorithms_guaranteed and
2661 algorithms_avaiable that respectively list the names of hash algorithms
2662 guaranteed to exist in all Python implementations and the names of hash
2663 algorithms available in the current process.
2664
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002665- A new package ``concurrent.futures`` as defined by PEP 3148.

2792 return characters from the full Unicode range, even on narrow unicode builds
2793 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2794 in Python is that unicodedata.numeric() now returns the correct value for
2795 large code points, and repr() may consider more characters as printable.
2796

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002813- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002814 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2815 objects are output as-is.

2819 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002820
Georg Brandl649971e2010-09-05 17:06:50 +00002821- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2822 use PyUnicode_FromFormatV() to format the warning message.

2830 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002831
Georg Brandl649971e2010-09-05 17:06:50 +00002832- Issue #9416: Fix some issues with complex formatting where the output with no
2833 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002834
2835 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2836 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3167
Victor Stinner8182b712010-07-28 00:40:58 +00003168- Issue #8991: convertbuffer() rejects discontigious buffers.
3169
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003170- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3171 compiler.
3172
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003173- Issue #8413: structsequence now subclasses tuple.
3174
Ezio Melotti57221d02010-07-01 07:32:02 +00003175- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003176 start byte and the continuation byte(s) are now considered invalid, instead of
3177 the number of bytes specified by the start byte. E.g.:
3178 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3179 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3180 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3181 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003182
Georg Brandl62069d32010-07-31 08:56:11 +00003183- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3184 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003185
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003186- Be more specific in error messages about positional arguments.
3187
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003188- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3189 objects, as described in the documentation.

Georg Brandl62069d32010-07-31 08:56:11 +00003195- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3196 dealing with unary minus applied to a constant. The removed code was mutating
3197 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003198
Victor Stinner554f3f02010-06-16 23:33:54 +00003199- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003200 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003201 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003202 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003203
Victor Stinner25e8ec42010-06-25 00:02:38 +00003204- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3205 "w*" format instead. Add tests for "w*" format.
3206
Victor Stinner06e49dd2010-06-13 18:21:50 +00003207- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003208 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003209 string formats.
3210
Georg Brandl62069d32010-07-31 08:56:11 +00003211- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003212 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3213 location of the raised exception.
3214
Victor Stinner313a1202010-06-11 23:56:51 +00003215- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3216 filenames and enable os.fsencode().
3217
Benjamin Peterson285a6892010-06-22 19:21:52 +00003218- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3219
Georg Brandl62069d32010-07-31 08:56:11 +00003220- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3221 interpreter with characters outside the Basic Multilingual Plane (higher than
3222 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003223
Georg Brandl62069d32010-07-31 08:56:11 +00003224- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3225 TypeError instead of giving a DeprecationWarning when a float is parsed using
3226 the 'L' code (for long long). (All other integer codes already raise
3227 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003228
Victor Stinner600d3be2010-06-10 12:00:55 +00003229- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3230 enable shortcuts for upper case encoding name. Add also a shortcut for
3231 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3232
Georg Brandl62069d32010-07-31 08:56:11 +00003233- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3234 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003235
3236- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003237 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003238 like bytearray.
3239
Georg Brandl62069d32010-07-31 08:56:11 +00003240- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003241 used anymore and it was never documented.
3242
Georg Brandl62069d32010-07-31 08:56:11 +00003243- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003244
Georg Brandl62069d32010-07-31 08:56:11 +00003245- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3246 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003247
Georg Brandl62069d32010-07-31 08:56:11 +00003248- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3249 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3250 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3251 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003252
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003253- Issue #8748: Fix two issues with comparisons between complex and integer
3254 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003255 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3256 (2) The comparison raised an OverflowError for large integers, leading to
3257 unpredictable exceptions when combining integers and complex objects in sets
3258 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003259
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003260- Issue #8766: Initialize _warnings module before importing the first module.
3261 Fix a crash if an empty directory called "encodings" exists in sys.path.
3262
Victor Stinner9ca9c252010-05-19 16:53:30 +00003263- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003264 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003265 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003266
Georg Brandl62069d32010-07-31 08:56:11 +00003267- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3268 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003269
Victor Stinnerae6265f2010-05-15 16:27:27 +00003270- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3271 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003272 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003273 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003274
Victor Stinner59e62db2010-05-15 13:14:32 +00003275- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003276 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003277
Victor Stinnerb744ba12010-05-15 12:27:16 +00003278- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003279 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003280 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3281
Victor Stinner0964ee12010-04-30 16:48:45 +00003282- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003283 PyUnicode_FromString() to support surrogates in the filename and use the right
3284 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003285
Georg Brandl8569e582010-05-19 20:57:08 +00003286- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3287
Georg Brandl62069d32010-07-31 08:56:11 +00003288- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003289
Benjamin Petersonfb886362010-04-24 18:21:17 +00003290- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3291 arguments.
3292
Victor Stinner14284c22010-04-23 12:02:30 +00003293- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003294 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3295 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003296
Victor Stinner31be90b2010-04-22 19:38:16 +00003297- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00003299
Georg Brandl62069d32010-07-31 08:56:11 +00003300- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3301 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003302
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003303- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003304 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3305 compared to the dynamic memory allocation fallback. Patch by Charles-François

3384 crash in many places because of the PyByteArray_AS_STRING() macro returning
3385 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003387- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003388 where the right hand operand is a set of constants, by turning the set into a
3389 frozenset and pre-building it as a constant. The comparison operation is made
3390 against the constant instead of building a new set each time it is executed (a
3391 similar optimization already existed which turned a list of constants into a
3392 pre-built tuple). Patch and additional tests by Dave Malcolm.

3399 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3400 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3401 parsing certain long numeric strings corresponding to subnormal values, (3) a

3418 of integers: the result of a/b is now correctly rounded for ints a and b (at
3419 least on IEEE 754 platforms), and in particular does not depend on the
3420 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00003697 applications that use a lot of regular expressions and limits the impact of
3698 the performance hit anytime the cache is exceeded.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004071 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004072 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00004107- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4108 InvalidOperation instead of returning False. (Comparisons involving a quiet
4109 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4110 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004112- Issue #2531: Comparison operations between floats and Decimal instances now
4113 return a result based on the numeric values of the operands; previously they
4114 returned an arbitrary result based on the relative ordering of id(float) and
4115 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4116 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004117
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004118- Added a subtract() method to collections.Counter().
4119
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004120- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004121 argument `-` which tells it to read files to compile from stdin. Each line is
4122 read on demand and the named file is compiled immediately. (Original patch by
4123 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004125- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004129- Comparisons using one of <, <=, >, >= between a complex instance and a
4130 Fractions instance now raise TypeError instead of returning True/False. This
4131 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4132 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004175- The internals of the subprocess module on POSIX systems have been replaced by
4176 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4177 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004178
Georg Brandl62069d32010-07-31 08:56:11 +00004179- subprocess.Popen now has restore_signals and start_new_session features. The
4180 default of restore_signals=True is a new behavior compared to earlier Python
4181 versions. This means that signals such as SIGPIPE are not ignored by default
4182 in subprocesses launched by Python (Issue #1652).

4269 position when calling `truncate()`. It would previously change the file
4270 position to the given argument, which goes against the tradition of

4275 archive. The new implementation is significantly faster and can be wrapped in
4276 a :class:`io.BufferedReader` object for more speedups. It also solves an
4277 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004613- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004614 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4615 PyPycLoader inherit from this class and provide implementations in relation to
4616 other methods required by the ABCs.

Brett Cannon64ef00f2009-07-20 03:19:18 +00004618- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4619 the documentation said it did even though the code in PyLoader relied on the
4620 abstract method required by ResourceLoader.
4621
Georg Brandl62069d32010-07-31 08:56:11 +00004622- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004675- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004676 compared to other unix systems. In particular, os.getgroups() does not reflect
4677 any changes made using os.setgroups() but basicly always returns the same
4678 information as the id command. os.getgroups() can now return more than 16
4679 groups on MacOSX.

4705 Prior to this change, timezone adjustment in utctimetuple() could produce
4706 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4711 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4712 ``datetime.timezone`` instance constructed from the parsed offset. If both

4718 ``datetime.timezone``, return fixed name and UTC offset from their
4719 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4720 returns ``None``. A class attribute, ``utc`` contains an instance

5277 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5278 corrects a pydoc regression.
5279
Georg Brandl5f90d792010-08-01 22:31:05 +00005280- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005281 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005322*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005323
5324Core and Builtins
5325-----------------
5326
Mark Dickinson865e01a2009-05-07 16:37:01 +00005327- Issue #5914: Add new C API function PyOS_string_to_double, and
5328 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5329
Eric Smith741191f2009-05-06 13:08:15 +00005330- Issue #3382: float.__format__, complex.__format__, and %-formatting
5331 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5332 affects nan -> NAN and inf -> INF.
5333
Mark Hammond5a607a32009-05-06 08:04:54 +00005334- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5335 in all operations, including splitdrive, split, etc. splitunc() now issues
5336 a PendingDeprecation warning.
5337
Eric Smith63376222009-05-05 14:04:18 +00005338- Issue #5920: For float.__format__, change the behavior with the
5339 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5340 to be like 'g' but with at least one decimal point and with a
5341 default precision of 12. Previously, the behavior the same but with
5342 a default precision of 6. This more closely matches str(), and
5343 reduces surprises when adding alignment flags to the empty
5344 presentation type. This also affects the new complex.__format__ in
5345 the same way.
5346
Martin v. Löwis011e8422009-05-05 04:43:17 +00005347- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5348
R. David Murrayb18500d2009-05-04 22:59:07 +00005349- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5350 shadowed by classtype's, even if it was None. property now
5351 inserts the __doc__ into the subclass instance __dict__.
5352
Antoine Pitrou244651a2009-05-04 18:56:13 +00005353- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5354 sequences. Patch by Nick Barnes and Victor Stinner.
5355
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005356- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005357
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005358- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5359 received a new method, detach(). detach() disconnects the underlying stream
5360 from the buffer or text IO and returns it.
5361
Mark Dickinson33841c32009-05-01 15:37:04 +00005362- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5363 floats with absolute value over 1e50. Also remove length
5364 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5365 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005366
Eric Smith741191f2009-05-06 13:08:15 +00005367- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005368 format(complex(1, 2./3), '.5') now produces a sensible result.
5369
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005370- Issue #5864: Fix empty format code formatting for floats so that it
5371 never gives more than the requested number of significant digits.
5372
Eric Smith6dc46f52009-04-27 20:39:49 +00005373- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5374 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5375
Eric Smithcc32a112009-04-26 21:35:14 +00005376- Issue #5835: Deprecate PyOS_ascii_formatd.
5377
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005378- Issue #4971: Fix titlecase for characters that are their own
5379 titlecase, but not their own uppercase.
5380
Benjamin Peterson193152c2009-04-25 01:08:45 +00005381- Issue #5283: Setting __class__ in __del__ caused a segfault.
5382
Mark Dickinsonad476da2009-04-23 19:14:16 +00005383- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5384 z involves nans, infs or negative zeros.
5385
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005386- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005387
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005388- Issue #1869 (and many duplicates): make round(x, n) correctly
5389 rounded for a float x, by using the decimal <-> binary conversions
5390 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5391 consistently agrees with format(x, '.2f').
5392
Benjamin Petersonae937c02009-04-18 20:54:08 +00005393- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5394 some builtin types.
5395
Eric Smith0923d1d2009-04-16 20:16:10 +00005396- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5397
Eric Smith35e84722009-04-16 20:21:28 +00005398- Issue #5515: str.format() type 'n' combined with commas and leading
5399 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005400
5401- Implement PEP 378, Format Specifier for Thousands Separator, for
5402 floats.
5403
Mark Dickinson3370cce2009-04-17 22:40:53 +00005404- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005405 1e11, not 1e12. This avoids printing 13 significant digits in
5406 situations where only 12 of them are correct. Example problem
5407 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5408 long time.)
5409
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005410- Issue #1580: On most platforms, use a 'short' float repr: for a
5411 finite float x, repr(x) now outputs a string based on the shortest
5412 sequence of decimal digits that rounds to x. Previous behaviour was
5413 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005414 Another minor difference is that the new repr switches to
5415 exponential notation at 1e16 instead of the previous 1e17; this
5416 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005417
5418 There's a new sys attribute sys.float_repr_style, which takes
5419 the value 'short' to indicate that we're using short float repr,
5420 and 'legacy' if the short float repr isn't available for one
5421 reason or another.
5422
5423 The float repr change involves incorporating David Gay's 'perfect
5424 rounding' code into the Python core (it's in Python/dtoa.c). As a
5425 secondary consequence, all string-to-float and float-to-string
5426 conversions (including all float formatting operations) will be
5427 correctly rounded on these platforms.
5428
Georg Brandl5f90d792010-08-01 22:31:05 +00005429 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005430 this change does not apply.
5431
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005432- Issue #5759: float() didn't call __float__ on str subclasses.
5433
Georg Brandlabc38772009-04-12 15:51:51 +00005434- The string.maketrans() function is deprecated; there is a new static method
5435 maketrans() on the bytes and bytearray classes. This removes confusion about
5436 the types string.maketrans() is supposed to work with, and mirrors the
5437 methods available on the str class.
5438
R. David Murraydc6da8a2009-04-09 22:16:43 +00005439- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5440 its clarity and its speed.
5441
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005442- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005443 to avoid compiler warnings.
5444
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005445- Issue #3739: The unicode-internal encoder now reports the number of characters
5446 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005583- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5584
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005585- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5586 byte, and the 'C' code only accepts a unicode character.
5587
Georg Brandl406b3d82009-04-11 21:24:37 +00005588- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5589 when hitting the recursion limit under certain circumstances.
5590
Brett Cannon0759dd62009-04-01 18:13:07 +00005591- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5592
Georg Brandlab6f2f62009-03-31 04:16:10 +00005593- Fix a segfault when running test_exceptions with coverage, caused by
5594 insufficient checks in accessors of Exception.__context__.
5595
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005596- Issue #5604: non-ASCII characters in module name passed to
5597 imp.find_module() were converted to UTF-8 while the path is
5598 converted to the default filesystem encoding, causing nonsense.
5599
Benjamin Peterson09832742009-03-26 17:15:46 +00005600- Issue #5126: str.isprintable() returned False for space characters.
5601
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005602- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5603 the end sys.path, for compatibility with the system install of Python.
5604
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005605- Issue #4688: Add a heuristic so that tuples and dicts containing only
5606 untrackable objects are not tracked by the garbage collector. This can
5607 reduce the size of collections and therefore the garbage collection overhead
5608 on long-running programs, depending on their particular use of datatypes.
5609
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005610- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5613
Mark Dickinsonbd792642009-03-18 20:06:12 +00005614- Issue #4258: Make it possible to use base 2**30 instead of base
5615 2**15 for the internal representation of integers, for performance
5616 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5617 --enable-big-digits option to configure, which overrides the
5618 default. Add sys.int_info structseq to provide information about
5619 the internal format.
5620
Mark Dickinson081dfee2009-03-18 14:47:41 +00005621- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5622 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5623 and sizeof(Py_UNICODE) == 2.
5624
Eric Smith8ec90442009-03-14 12:29:34 +00005625- Issue #5237: Allow auto-numbered fields in str.format(). For
5626 example: '{} {}'.format(1, 2) == '1 2'.
5627
Antoine Pitrou652e7072009-03-13 19:25:20 +00005628- Issue #5392: when a very low recursion limit was set, the interpreter would
5629 abort with a fatal error after the recursion limit was hit twice.
5630
Matthias Klose042f1332009-04-04 14:32:42 +00005631- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5632 short file names.

R. David Murray548ac412009-04-02 19:44:43 +00005638 mailbox.MH.get_message().
5639
Hye-Shik Chang944820b2009-04-02 10:33:16 +00005640- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
5641 error substitutions from non-strict codec error callbacks in
5642 incrementalencoder and StreamWriter.
5643
Georg Brandl33c28812009-04-01 23:07:29 +00005644- Issue #5656: Fix the coverage reporting when running the test suite with

5662
Brett Cannon7f6b4f82009-03-30 21:30:26 +00005663- Issue #5236: Change time.strptime() to only take strings. Didn't work with
5664 bytes already but the failure was non-obvious.
5665
Jesse Noller7af4ef82009-03-30 16:47:15 +00005666- Issue #5177: Multiprocessing's SocketListener class now uses

5674
Benjamin Peterson59406a92009-03-26 17:10:29 +00005675- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
5676 io.BufferedRandom have been deprecated for removal in Python 3.2.
5677
Lars Gustäbel42e00912009-03-22 20:34:29 +00005678- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5679 forever on incomplete input. That caused tarfile.open() to hang when used
5680 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5681 partial bzip2 compressed data.
5682
Mark Dickinson79f52032009-03-17 23:12:51 +00005683- Issue #2110: Add support for thousands separator and 'n' type

5687 '>' alignment characters.
5688
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005689- The error detection code in FileIO.close() could fail to reflect the `errno`
5690 value, and report it as -1 instead.

5699
Mark Dickinsonae681df2009-03-21 10:26:31 +00005700- Issue #5463: In struct module, remove deprecated overflow wrapping
5701 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005702 struct.error instead of returning b'\xff\xff\xff\xff'. The
5703 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5704 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005731- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5732 it now forces its argument to double before testing for infinity.
5733
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005734- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5735 returns a non-number type.
5736
Benjamin Peterson87618552009-02-08 15:00:52 +00005737- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005743
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005744- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005745 were suppressing all exceptions. These include list() and bytearray().
5746
Mark Dickinson1124e712009-01-28 21:25:58 +00005747- Issue #4707: round(x, n) now returns an integer if x is an integer.
5748 Previously it returned a float.

5751 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5752 evaluation loop is compiled with a new dispatch mechanism which gives
5753 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00005766 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005767
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005768- Issue #4935: The overflow checking code in the expandtabs() method common
5769 to str, bytes and bytearray could be optimized away by the compiler, letting
5770 the interpreter segfault instead of raising an error.
5771
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005772- Issue #3720: Fix a crash when an iterator modifies its class and removes its

5784 common cases are optimized thanks to a dedicated fast path and a moderate
5785 amount of loop unrolling.
5786
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005787- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5788 collecting the oldest generation) so that allocating lots of objects without
5789 destroying them does not show quadratic performance. Based on a proposal by
5790 Martin von Löwis at
5791 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5792
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005793- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005794 having been closed (for instance, a read() call could return some
5795 previously buffered data). Patch by Dmitry Vasiliev.
5796
Antoine Pitrou05608432009-01-09 18:53:14 +00005797- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5798 flag to work properly. Furthermore, when specifying -u, the text stdout
5799 and stderr streams have line-by-line buffering enabled (the default being
5800 to buffer arbitrary chunks of data).
5801
Raymond Hettinger35631532009-01-09 03:58:09 +00005802- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5803 instead of ints (reducing its size from 4 to 8 times thereby reducing
5804 Python's overall memory).
5805
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005806- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5807 an existing .py counterpart, override the co_filename attributes of all
5808 code objects if the original filename is obsolete (which can happen if the
5809 file has been renamed, moved, or if it is accessed through different paths).
5810 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5811
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005812- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5813 one byte. Also fixes the meaning of len() so that it returns the number of
5814 items, rather than the size in bytes.
5815
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005816- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5817
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005818- Issue #4747: When the terminal does not use utf-8, executing a script with
5819 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5820

5825 did not get collected.
5826
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005827- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5828 where the tp_hash and tp_dict slots are both NULL.
5829
Georg Brandlccc47b62008-12-28 11:44:14 +00005830- Issue #4759: None is now allowed as the first argument of
5831 bytearray.translate(). It was always allowed for bytes.translate().
5832
Skip Montanaro80072cb2008-12-23 03:51:14 +00005833- Added test case to ensure attempts to read from a file opened for writing
5834 fail.

5840
Antoine Pitrou621601a2008-12-17 23:18:19 +00005841- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5842 print elapsed times, not only when some objects are uncollectable /
5843 unreachable. Original patch by Neil Schemenauer.
5844

5846
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005847- Issue #2173: When getting device encoding, check that return value of
5848 nl_langinfo is not the empty string. This was causing silent build
5849 failures on OS X.
5850
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005851- Issue #4597: Fixed several opcodes that weren't always propagating
5852 exceptions.
5853
5854- Issue #4589: Fixed exception handling when the __exit__ function of a

Antoine Pitrou08838b62009-01-21 00:55:13 +00006204- Issue #5008: When a file is opened in append mode with the new IO library,
6205 do an explicit seek to the end of file (so that e.g. tell() returns the

6237 appropriately when it is being used via socket.makefile() objects
6238 rather than delaying the close by waiting for garbage collection to do it.
6239
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006240- Issue #1696199: Add collections.Counter() for rapid and convenient

6490 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6491 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6492 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006495 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006496 from test support, which does the conversion.
