Ned Deily657b2de2011-06-28 19:51:30 -0700805- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
806 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
807 interpreter process. This could cause failures in non-Distutils subprocesses
808 and was unreliable since tests or user programs could modify the interpreter
809 environment after Distutils set it. Instead, have Distutils set the the
810 deployment target only in the environment of each build subprocess. It is
811 still possible to globally override the default by setting
812 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
813 greater or equal to the default value, the value with which the interpreter

1966- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001967 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Georg Brandl255abdd2011-01-16 14:17:26 +00002066 continuation line in the formatted value has no leading white space and looks
2067 like a header. Since Generator uses Header to format all headers, this check
2068 is made for all headers in any serialized message at serialization time. This
2069 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00002079 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002080
Éric Araujof0ab5d62011-05-29 03:43:59 +02002081- email.header.Header was incorrectly encoding folding whitespace when

2083 folding whitespace. It now uses the continuation_ws, as it does for

2089 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2090 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2091 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

3121 with a non-empty format string. This is an effort to future-proof user
3122 code. If a derived class does not currently implement __format__ but later
3123 adds its own __format__, it would most likely break user code that had
3124 supplied a format string. This will be changed to a DeprecationWaring in
3125 Python 3.3 and it will be an error in Python 3.4.

3129 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003138- Issue #4617: Previously it was illegal to delete a name from the local
3139 namespace if it occurs as a free variable in a nested block. This limitation
3140 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3141
Georg Brandl27a28582010-10-10 09:49:21 +00003142- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3143 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3144 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3145 single character on UCS-2 builds.

Antoine Pitrou079ce542010-09-08 12:37:10 +00003151- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003180- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003181 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003182 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003183 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003208 retry the select() loop instead of bailing out. This is because select() can
3209 incorrectly report a socket as ready for reading (for example, if it received
3210 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003290- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003291 it possible for the user to create self-referencing ordered dictionaries which
3292 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003293 approach of using weakref proxies so that reference cycles never get created
3294 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003337 * Update the seed() method to use all of the bits in a string instead of just
3338 the hash value. This makes better use of the seed value and assures the
3339 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003341 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3342 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3343 which has a slight bias whenever n is not a power of two. Issue #9025.

3345 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003364- hashlib has two new constant attributes: algorithms_guaranteed and

3366 guaranteed to exist in all Python implementations and the names of hash
3367 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003472- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3473 now removed, since their effect was inexistent in 3.x (the default encoding is
3474 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003475
Antoine Pitroub0fa8312010-09-01 15:10:12 +00003476- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

3480 platforms. Previously, it inlined only when using Microsoft Visual C.

3496 return characters from the full Unicode range, even on narrow unicode builds
3497 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3498 in Python is that unicodedata.numeric() now returns the correct value for
3499 large code points, and repr() may consider more characters as printable.
3500
Victor Stinner6c00c142010-08-17 23:37:11 +00003501- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003517- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003518 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3519 objects are output as-is.

Antoine Pitrou042b1282010-08-13 21:15:58 +00003524
Georg Brandl649971e2010-09-05 17:06:50 +00003525- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3526 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003527

3534 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003535
Georg Brandl649971e2010-09-05 17:06:50 +00003536- Issue #9416: Fix some issues with complex formatting where the output with no
3537 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003538
3539 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3540 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003957- Issue #8748: Fix two issues with comparisons between complex and integer
3958 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003959 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3960 (2) The comparison raised an OverflowError for large integers, leading to
3961 unpredictable exceptions when combining integers and complex objects in sets

4263
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004264- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
4265 variable argument list. `Py_VA_COPY` is equivalent to C99
4266 `va_copy`, but available on all python platforms.
4267
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004268- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4269 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4270 "step = -step" when reversing a slice.
4271
Georg Brandl62069d32010-07-31 08:56:11 +00004272- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

Antoine Pitrou8689a102010-04-01 16:53:15 +00004280- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00004281 function declaration, which was kept for backwards compatibility reasons, is
4282 now removed (the macro was introduced in 1997!).

Georg Brandl62069d32010-07-31 08:56:11 +00004291 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
4292 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4293 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004294 to match the behaviour of the other integer format codes.
4295
Georg Brandl62069d32010-07-31 08:56:11 +00004296- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00004304- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4305 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4306 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00004307

4319 ``const char *`` as the string is stored beyond the call.
4320
Georg Brandl62069d32010-07-31 08:56:11 +00004321- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4322 allocator will be automatically disabled when running under Valgrind. This
4323 gives improved memory leak detection when running under Valgrind, while taking
4324 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004397- The default size of the re module's compiled regular expression cache has been

Antoine Pitrou3060c452010-08-13 16:27:38 +00004399 simply clearing the entire cache on overflow to forgetting the least recently
4400 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004401 applications that use a lot of regular expressions and limits the impact of
4402 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004656- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4657 operation raises multiple signals and more than one of those signals is
4658 trapped, the specification determines the order in which the signals should be
4659 handled. In many cases this order wasn't being followed, leading to the wrong
4660 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004699- Issue #8524: When creating an SSL socket, the timeout value of the original
4700 socket wasn't retained (instead, a socket with a positive timeout would be
4701 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004702
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004703- Issue #5103: SSL handshake would ignore the socket timeout and block

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004824- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004825 argument `-` which tells it to read files to compile from stdin. Each line is
4826 read on demand and the named file is compiled immediately. (Original patch by
4827 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004829- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004833- Comparisons using one of <, <=, >, >= between a complex instance and a
4834 Fractions instance now raise TypeError instead of returning True/False. This
4835 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4836 <=> complex, and complex <=> complex comparisons.

4880 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4881 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004883- subprocess.Popen now has restore_signals and start_new_session features. The
4884 default of restore_signals=True is a new behavior compared to earlier Python
4885 versions. This means that signals such as SIGPIPE are not ignored by default
4886 in subprocesses launched by Python (Issue #1652).

5297 occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
5298 "wb+" mode) after having buffered a certain amount of data for reading. This
5299 bug was not present in the pure Python implementation.

Brett Cannon69194272009-07-20 04:23:48 +00005317- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005318 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5319 PyPycLoader inherit from this class and provide implementations in relation to
5320 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005321
Brett Cannon64ef00f2009-07-20 03:19:18 +00005322- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5323 the documentation said it did even though the code in PyLoader relied on the
5324 abstract method required by ResourceLoader.
5325
Georg Brandl62069d32010-07-31 08:56:11 +00005326- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00005374- Issue #9959: Tweak formula used for computing math.log of an integer,
5375 making it marginally more accurate for exact powers of 2.

5378
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005379- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005380 compared to other unix systems. In particular, os.getgroups() does not reflect
5381 any changes made using os.setgroups() but basicly always returns the same
5382 information as the id command. os.getgroups() can now return more than 16
5383 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005408- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5409 Prior to this change, timezone adjustment in utctimetuple() could produce
5410 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5411 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005413- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5414 directive. When the ``%z`` directive is present in the format string, an
5415 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5416 ``datetime.timezone`` instance constructed from the parsed offset. If both
5417 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5418 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005421 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5422 ``datetime.timezone``, return fixed name and UTC offset from their
5423 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5424 returns ``None``. A class attribute, ``utc`` contains an instance
5425 representing the UTC timezone. Original patch by Rafe Kaplan.

5442 with an improved 'binary-split' algorithm that uses fewer multiplications and
5443 allows many of the multiplications to be performed using plain C integer
5444 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005450- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5451 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005452 the result is now always correctly rounded, and is equivalent to ``td /
5453 timedelta(seconds=1)``.

5462 integer format code, struct.pack first attempts to convert the non-integer
5463 using its __index__ method. If that method is non-existent or raises
5464 TypeError it goes on to try the __int__ method, as described below.

6045 default precision of 12. Previously, the behavior the same but with
6046 a default precision of 6. This more closely matches str(), and
6047 reduces surprises when adding alignment flags to the empty
6048 presentation type. This also affects the new complex.__format__ in
6049 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00006062- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6063 received a new method, detach(). detach() disconnects the underlying stream
6064 from the buffer or text IO and returns it.
6065
Mark Dickinson33841c32009-05-01 15:37:04 +00006066- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6067 floats with absolute value over 1e50. Also remove length
6068 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6069 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00006071- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006072 format(complex(1, 2./3), '.5') now produces a sensible result.
6073
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006074- Issue #5864: Fix empty format code formatting for floats so that it
6075 never gives more than the requested number of significant digits.
6076
Eric Smith6dc46f52009-04-27 20:39:49 +00006077- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6078 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6079

Martin v. Löwis71efeb72009-04-26 01:02:07 +00006082- Issue #4971: Fix titlecase for characters that are their own
6083 titlecase, but not their own uppercase.
6084
Benjamin Peterson193152c2009-04-25 01:08:45 +00006085- Issue #5283: Setting __class__ in __del__ caused a segfault.
6086
Mark Dickinsonad476da2009-04-23 19:14:16 +00006087- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6088 z involves nans, infs or negative zeros.
6089
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006090- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006091
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006092- Issue #1869 (and many duplicates): make round(x, n) correctly
6093 rounded for a float x, by using the decimal <-> binary conversions
6094 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6095 consistently agrees with format(x, '.2f').
6096
Benjamin Petersonae937c02009-04-18 20:54:08 +00006097- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6098 some builtin types.
6099
Eric Smith0923d1d2009-04-16 20:16:10 +00006100- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6101
Eric Smith35e84722009-04-16 20:21:28 +00006102- Issue #5515: str.format() type 'n' combined with commas and leading
6103 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006104
6105- Implement PEP 378, Format Specifier for Thousands Separator, for
6106 floats.
6107
Mark Dickinson3370cce2009-04-17 22:40:53 +00006108- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006109 1e11, not 1e12. This avoids printing 13 significant digits in
6110 situations where only 12 of them are correct. Example problem
6111 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6112 long time.)
6113
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006114- Issue #1580: On most platforms, use a 'short' float repr: for a
6115 finite float x, repr(x) now outputs a string based on the shortest
6116 sequence of decimal digits that rounds to x. Previous behaviour was
6117 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006118 Another minor difference is that the new repr switches to
6119 exponential notation at 1e16 instead of the previous 1e17; this
6120 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006121
6122 There's a new sys attribute sys.float_repr_style, which takes
6123 the value 'short' to indicate that we're using short float repr,
6124 and 'legacy' if the short float repr isn't available for one
6125 reason or another.
6126
6127 The float repr change involves incorporating David Gay's 'perfect
6128 rounding' code into the Python core (it's in Python/dtoa.c). As a
6129 secondary consequence, all string-to-float and float-to-string
6130 conversions (including all float formatting operations) will be
6131 correctly rounded on these platforms.
6132
Georg Brandl5f90d792010-08-01 22:31:05 +00006133 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006134 this change does not apply.
6135
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006136- Issue #5759: float() didn't call __float__ on str subclasses.
6137
Georg Brandlabc38772009-04-12 15:51:51 +00006138- The string.maketrans() function is deprecated; there is a new static method
6139 maketrans() on the bytes and bytearray classes. This removes confusion about
6140 the types string.maketrans() is supposed to work with, and mirrors the
6141 methods available on the str class.
6142
R. David Murraydc6da8a2009-04-09 22:16:43 +00006143- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6144 its clarity and its speed.
6145
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006146- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006147 to avoid compiler warnings.
6148
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006149- Issue #3739: The unicode-internal encoder now reports the number of characters
6150 consumed like any other encoder (instead of the number of bytes).

6308
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006309- Issue #4688: Add a heuristic so that tuples and dicts containing only
6310 untrackable objects are not tracked by the garbage collector. This can
6311 reduce the size of collections and therefore the garbage collection overhead
6312 on long-running programs, depending on their particular use of datatypes.

6319 2**15 for the internal representation of integers, for performance
6320 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6321 --enable-big-digits option to configure, which overrides the
6322 default. Add sys.int_info structseq to provide information about
6323 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00006325- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6326 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6327 and sizeof(Py_UNICODE) == 2.
6328
Eric Smith8ec90442009-03-14 12:29:34 +00006329- Issue #5237: Allow auto-numbered fields in str.format(). For

6433 rotating the object pointer by 4 bits to the right.
6434
Mark Dickinson87ec0852009-02-09 17:15:59 +00006435- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6436 it now forces its argument to double before testing for infinity.
6437
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006438- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6439 returns a non-number type.
6440
Benjamin Peterson87618552009-02-08 15:00:52 +00006441- Issue #5182: Removed memoryview.__str__.
6442
Mark Dickinsonc008a172009-02-01 13:59:22 +00006443- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006447
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006448- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006449 were suppressing all exceptions. These include list() and bytearray().
6450
Mark Dickinson1124e712009-01-28 21:25:58 +00006451- Issue #4707: round(x, n) now returns an integer if x is an integer.
6452 Previously it returned a float.
6453
Antoine Pitroub52ec782009-01-25 16:34:23 +00006454- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6455 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6456 evaluation loop is compiled with a new dispatch mechanism which gives
6457 speedups of up to 20%, depending on the system, on various benchmarks.
6458
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006459- Issue #4874: Most builtin decoders now reject unicode input.

6467 optional module state data.
6468
Mark Dickinson8055afd2009-01-17 10:04:45 +00006469- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006470 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006471
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006472- Issue #4935: The overflow checking code in the expandtabs() method common
6473 to str, bytes and bytearray could be optimized away by the compiler, letting
6474 the interpreter segfault instead of raising an error.
6475
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006476- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6477 __next__ method.
6478
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006479- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6480 function no longer attempt to call the __long__ slot to convert an object
6481 to an integer. Only the __int__ and __trunc__ slots are examined.
6482
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006483- Issue #4893: Use NT threading on CE.
6484

6486
Antoine Pitrouab868312009-01-10 15:40:25 +00006487- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6488 common cases are optimized thanks to a dedicated fast path and a moderate
6489 amount of loop unrolling.
6490
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006491- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6492 collecting the oldest generation) so that allocating lots of objects without
6493 destroying them does not show quadratic performance. Based on a proposal by
6494 Martin von Löwis at
6495 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6496
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006497- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006498 having been closed (for instance, a read() call could return some
6499 previously buffered data). Patch by Dmitry Vasiliev.
6500
Antoine Pitrou05608432009-01-09 18:53:14 +00006501- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6502 flag to work properly. Furthermore, when specifying -u, the text stdout
6503 and stderr streams have line-by-line buffering enabled (the default being
6504 to buffer arbitrary chunks of data).
6505
Raymond Hettinger35631532009-01-09 03:58:09 +00006506- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6507 instead of ints (reducing its size from 4 to 8 times thereby reducing
6508 Python's overall memory).
6509
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006510- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6511 an existing .py counterpart, override the co_filename attributes of all
6512 code objects if the original filename is obsolete (which can happen if the
6513 file has been renamed, moved, or if it is accessed through different paths).
6514 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6515
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006516- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6517 one byte. Also fixes the meaning of len() so that it returns the number of
6518 items, rather than the size in bytes.
6519
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006520- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6521
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006522- Issue #4747: When the terminal does not use utf-8, executing a script with
6523 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6524
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006525- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6526 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006527
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006528- Issue #3680: Reference cycles created through a dict, set or deque iterator
6529 did not get collected.
6530
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006531- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6532 where the tp_hash and tp_dict slots are both NULL.
6533
Georg Brandlccc47b62008-12-28 11:44:14 +00006534- Issue #4759: None is now allowed as the first argument of
6535 bytearray.translate(). It was always allowed for bytes.translate().
6536
Skip Montanaro80072cb2008-12-23 03:51:14 +00006537- Added test case to ensure attempts to read from a file opened for writing
6538 fail.
6539
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006540- Issue #3106: Speedup some comparisons (str/str and int/int).

6543 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6544
Antoine Pitrou621601a2008-12-17 23:18:19 +00006545- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6546 print elapsed times, not only when some objects are uncollectable /
6547 unreachable. Original patch by Neil Schemenauer.
6548
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006549- Issue #3439: Add a bit_length method to int.
6550
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006551- Issue #2173: When getting device encoding, check that return value of
6552 nl_langinfo is not the empty string. This was causing silent build
6553 failures on OS X.
6554
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006555- Issue #4597: Fixed several opcodes that weren't always propagating
6556 exceptions.
6557
6558- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006559 context manager returns a value that cannot be converted to a bool.
6560
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006561- Issue #4445: Replace "sizeof(PyBytesObject)" with
6562 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6563 bytes instances. On a typical machine this saves 3 bytes of memory
6564 (on average) per allocation of a bytes instance.
6565
Christian Heimesa872de52008-12-05 08:26:55 +00006566- Issue #4533: File read operation was dreadfully slow due to a slowly
6567 growing read buffer. Fixed by using the same growth rate algorithm as
6568 Python 2.x.
6569
Antoine Pitrou5504e892008-12-06 21:27:53 +00006570- Issue #4509: Various issues surrounding resize of bytearray objects to
6571 which there are buffer exports (e.g. memoryview instances).
6572
Georg Brandlf9734072008-12-07 15:30:06 +00006573- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6574 method on file objects with closefd=False. The file descriptor is still
6575 kept open but the file object behaves like a closed file. The ``FileIO``
6576 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006577
Antoine Pitroubc420402008-12-07 20:14:49 +00006578- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6579 larger than 1.

6584
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006585- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6586 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6587 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6588 of using the replace error handler in PyUnicode_DecodeUTF8().
