Ned Deily657b2de2011-06-28 19:51:30 -0700809- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
810 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
811 interpreter process. This could cause failures in non-Distutils subprocesses
812 and was unreliable since tests or user programs could modify the interpreter
813 environment after Distutils set it. Instead, have Distutils set the the
814 deployment target only in the environment of each build subprocess. It is
815 still possible to globally override the default by setting
816 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
817 greater or equal to the default value, the value with which the interpreter

Georg Brandl255abdd2011-01-16 14:17:26 +00002070 continuation line in the formatted value has no leading white space and looks
2071 like a header. Since Generator uses Header to format all headers, this check
2072 is made for all headers in any serialized message at serialization time. This
2073 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00002083 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002084
Éric Araujof0ab5d62011-05-29 03:43:59 +02002085- email.header.Header was incorrectly encoding folding whitespace when

2093 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2094 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2095 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

3125 with a non-empty format string. This is an effort to future-proof user
3126 code. If a derived class does not currently implement __format__ but later
3127 adds its own __format__, it would most likely break user code that had
3128 supplied a format string. This will be changed to a DeprecationWaring in
3129 Python 3.3 and it will be an error in Python 3.4.

3133 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

3136 functions from the libc caused the methods .upper() and lower() to become
3137 locale aware and created subtly wrong results.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003142- Issue #4617: Previously it was illegal to delete a name from the local
3143 namespace if it occurs as a free variable in a nested block. This limitation
3144 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3145
Georg Brandl27a28582010-10-10 09:49:21 +00003146- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3147 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3148 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3149 single character on UCS-2 builds.

Antoine Pitrou079ce542010-09-08 12:37:10 +00003155- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003184- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003185 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003186 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003187 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003212 retry the select() loop instead of bailing out. This is because select() can
3213 incorrectly report a socket as ready for reading (for example, if it received
3214 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003294- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003295 it possible for the user to create self-referencing ordered dictionaries which
3296 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003297 approach of using weakref proxies so that reference cycles never get created
3298 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003341 * Update the seed() method to use all of the bits in a string instead of just
3342 the hash value. This makes better use of the seed value and assures the
3343 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003345 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3346 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3347 which has a slight bias whenever n is not a power of two. Issue #9025.

3370 guaranteed to exist in all Python implementations and the names of hash
3371 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003476- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3477 now removed, since their effect was inexistent in 3.x (the default encoding is
3478 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003479

3500 return characters from the full Unicode range, even on narrow unicode builds
3501 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3502 in Python is that unicodedata.numeric() now returns the correct value for
3503 large code points, and repr() may consider more characters as printable.
3504
Victor Stinner6c00c142010-08-17 23:37:11 +00003505- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003521- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003522 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3523 objects are output as-is.

3527 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003528
Georg Brandl649971e2010-09-05 17:06:50 +00003529- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3530 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003531
Georg Brandl649971e2010-09-05 17:06:50 +00003532- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an

3538 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003539
Georg Brandl649971e2010-09-05 17:06:50 +00003540- Issue #9416: Fix some issues with complex formatting where the output with no
3541 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003542
3543 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3544 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3887 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3888 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3889 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003932- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3933 TypeError instead of giving a DeprecationWarning when a float is parsed using
3934 the 'L' code (for long long). (All other integer codes already raise
3935 TypeError in this case.)

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003961- Issue #8748: Fix two issues with comparisons between complex and integer
3962 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003963 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3964 (2) The comparison raised an OverflowError for large integers, leading to
3965 unpredictable exceptions when combining integers and complex objects in sets

4267
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004268- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
4269 variable argument list. `Py_VA_COPY` is equivalent to C99
4270 `va_copy`, but available on all python platforms.
4271
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004272- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4273 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4274 "step = -step" when reversing a slice.
4275
Georg Brandl62069d32010-07-31 08:56:11 +00004276- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

Antoine Pitrou8689a102010-04-01 16:53:15 +00004284- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00004285 function declaration, which was kept for backwards compatibility reasons, is
4286 now removed (the macro was introduced in 1997!).

Georg Brandl62069d32010-07-31 08:56:11 +00004295 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
4296 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4297 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004298 to match the behaviour of the other integer format codes.
4299

Georg Brandl62069d32010-07-31 08:56:11 +00004308- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4309 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4310 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00004311

4323 ``const char *`` as the string is stored beyond the call.
4324
Georg Brandl62069d32010-07-31 08:56:11 +00004325- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4326 allocator will be automatically disabled when running under Valgrind. This
4327 gives improved memory leak detection when running under Valgrind, while taking
4328 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004401- The default size of the re module's compiled regular expression cache has been
4402 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004403 simply clearing the entire cache on overflow to forgetting the least recently
4404 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004405 applications that use a lot of regular expressions and limits the impact of
4406 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004660- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4661 operation raises multiple signals and more than one of those signals is
4662 trapped, the specification determines the order in which the signals should be
4663 handled. In many cases this order wasn't being followed, leading to the wrong
4664 Python exception being raised.

4704 socket wasn't retained (instead, a socket with a positive timeout would be
4705 turned into a non-blocking SSL socket).

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004828- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004829 argument `-` which tells it to read files to compile from stdin. Each line is
4830 read on demand and the named file is compiled immediately. (Original patch by
4831 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004837- Comparisons using one of <, <=, >, >= between a complex instance and a
4838 Fractions instance now raise TypeError instead of returning True/False. This
4839 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4840 <=> complex, and complex <=> complex comparisons.

4884 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4885 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004887- subprocess.Popen now has restore_signals and start_new_session features. The
4888 default of restore_signals=True is a new behavior compared to earlier Python
4889 versions. This means that signals such as SIGPIPE are not ignored by default
4890 in subprocesses launched by Python (Issue #1652).

4983 archive. The new implementation is significantly faster and can be wrapped in
4984 a :class:`io.BufferedReader` object for more speedups. It also solves an
4985 issue where interleaved calls to `read()` and `readline()` give wrong results.

5301 occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
5302 "wb+" mode) after having buffered a certain amount of data for reading. This
5303 bug was not present in the pure Python implementation.

Georg Brandl62069d32010-07-31 08:56:11 +00005310- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
5311 digits in input, as recommended by the standard. Previously it was restricted
5312 to accepting [0-9].

Brett Cannon69194272009-07-20 04:23:48 +00005321- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005322 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5323 PyPycLoader inherit from this class and provide implementations in relation to
5324 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005325
Brett Cannon64ef00f2009-07-20 03:19:18 +00005326- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5327 the documentation said it did even though the code in PyLoader relied on the
5328 abstract method required by ResourceLoader.
5329
Georg Brandl62069d32010-07-31 08:56:11 +00005330- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00005378- Issue #9959: Tweak formula used for computing math.log of an integer,
5379 making it marginally more accurate for exact powers of 2.
5380
Mark Dickinsoncf28b952010-07-29 21:41:59 +00005381- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
5382
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005383- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005384 compared to other unix systems. In particular, os.getgroups() does not reflect
5385 any changes made using os.setgroups() but basicly always returns the same
5386 information as the id command. os.getgroups() can now return more than 16
5387 groups on MacOSX.

5408
Benjamin Petersonf751bc92010-07-02 13:46:42 +00005409- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as

Georg Brandl62069d32010-07-31 08:56:11 +00005412- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5413 Prior to this change, timezone adjustment in utctimetuple() could produce
5414 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5415 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005417- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5418 directive. When the ``%z`` directive is present in the format string, an
5419 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5420 ``datetime.timezone`` instance constructed from the parsed offset. If both
5421 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5422 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005424- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005425 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5426 ``datetime.timezone``, return fixed name and UTC offset from their
5427 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5428 returns ``None``. A class attribute, ``utc`` contains an instance
5429 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005445- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5446 with an improved 'binary-split' algorithm that uses fewer multiplications and
5447 allows many of the multiplications to be performed using plain C integer
5448 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5449 arguments.

5453
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005454- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5455 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005456 the result is now always correctly rounded, and is equivalent to ``td /
5457 timedelta(seconds=1)``.

5466 integer format code, struct.pack first attempts to convert the non-integer
5467 using its __index__ method. If that method is non-existent or raises
5468 TypeError it goes on to try the __int__ method, as described below.

6048 to be like 'g' but with at least one decimal point and with a
6049 default precision of 12. Previously, the behavior the same but with
6050 a default precision of 6. This more closely matches str(), and
6051 reduces surprises when adding alignment flags to the empty
6052 presentation type. This also affects the new complex.__format__ in
6053 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00006066- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6067 received a new method, detach(). detach() disconnects the underlying stream
6068 from the buffer or text IO and returns it.
6069
Mark Dickinson33841c32009-05-01 15:37:04 +00006070- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6071 floats with absolute value over 1e50. Also remove length
6072 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6073 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00006075- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006076 format(complex(1, 2./3), '.5') now produces a sensible result.
6077
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006078- Issue #5864: Fix empty format code formatting for floats so that it
6079 never gives more than the requested number of significant digits.
6080
Eric Smith6dc46f52009-04-27 20:39:49 +00006081- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6082 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6083
Eric Smithcc32a112009-04-26 21:35:14 +00006084- Issue #5835: Deprecate PyOS_ascii_formatd.
6085
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006086- Issue #4971: Fix titlecase for characters that are their own
6087 titlecase, but not their own uppercase.
6088
Benjamin Peterson193152c2009-04-25 01:08:45 +00006089- Issue #5283: Setting __class__ in __del__ caused a segfault.
6090
Mark Dickinsonad476da2009-04-23 19:14:16 +00006091- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6092 z involves nans, infs or negative zeros.
6093
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006094- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006095
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006096- Issue #1869 (and many duplicates): make round(x, n) correctly
6097 rounded for a float x, by using the decimal <-> binary conversions
6098 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6099 consistently agrees with format(x, '.2f').
6100
Benjamin Petersonae937c02009-04-18 20:54:08 +00006101- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6102 some builtin types.
6103
Eric Smith0923d1d2009-04-16 20:16:10 +00006104- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6105
Eric Smith35e84722009-04-16 20:21:28 +00006106- Issue #5515: str.format() type 'n' combined with commas and leading
6107 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006108
6109- Implement PEP 378, Format Specifier for Thousands Separator, for
6110 floats.
6111
Mark Dickinson3370cce2009-04-17 22:40:53 +00006112- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006113 1e11, not 1e12. This avoids printing 13 significant digits in
6114 situations where only 12 of them are correct. Example problem
6115 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6116 long time.)
6117
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006118- Issue #1580: On most platforms, use a 'short' float repr: for a
6119 finite float x, repr(x) now outputs a string based on the shortest
6120 sequence of decimal digits that rounds to x. Previous behaviour was
6121 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006122 Another minor difference is that the new repr switches to
6123 exponential notation at 1e16 instead of the previous 1e17; this
6124 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006125
6126 There's a new sys attribute sys.float_repr_style, which takes
6127 the value 'short' to indicate that we're using short float repr,
6128 and 'legacy' if the short float repr isn't available for one
6129 reason or another.
6130
6131 The float repr change involves incorporating David Gay's 'perfect
6132 rounding' code into the Python core (it's in Python/dtoa.c). As a
6133 secondary consequence, all string-to-float and float-to-string
6134 conversions (including all float formatting operations) will be
6135 correctly rounded on these platforms.
6136
Georg Brandl5f90d792010-08-01 22:31:05 +00006137 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006138 this change does not apply.
6139
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006140- Issue #5759: float() didn't call __float__ on str subclasses.
6141
Georg Brandlabc38772009-04-12 15:51:51 +00006142- The string.maketrans() function is deprecated; there is a new static method
6143 maketrans() on the bytes and bytearray classes. This removes confusion about
6144 the types string.maketrans() is supposed to work with, and mirrors the
6145 methods available on the str class.
6146
R. David Murraydc6da8a2009-04-09 22:16:43 +00006147- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6148 its clarity and its speed.
6149
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006150- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006151 to avoid compiler warnings.
6152
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006153- Issue #3739: The unicode-internal encoder now reports the number of characters
6154 consumed like any other encoder (instead of the number of bytes).

6312
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006313- Issue #4688: Add a heuristic so that tuples and dicts containing only
6314 untrackable objects are not tracked by the garbage collector. This can
6315 reduce the size of collections and therefore the garbage collection overhead
6316 on long-running programs, depending on their particular use of datatypes.

6323 2**15 for the internal representation of integers, for performance
6324 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6325 --enable-big-digits option to configure, which overrides the
6326 default. Add sys.int_info structseq to provide information about
6327 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00006329- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6330 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6331 and sizeof(Py_UNICODE) == 2.
6332
Eric Smith8ec90442009-03-14 12:29:34 +00006333- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00006439- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6440 it now forces its argument to double before testing for infinity.
6441
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006442- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6443 returns a non-number type.
6444
Benjamin Peterson87618552009-02-08 15:00:52 +00006445- Issue #5182: Removed memoryview.__str__.
6446
Mark Dickinsonc008a172009-02-01 13:59:22 +00006447- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006451
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006452- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006453 were suppressing all exceptions. These include list() and bytearray().
6454
Mark Dickinson1124e712009-01-28 21:25:58 +00006455- Issue #4707: round(x, n) now returns an integer if x is an integer.
6456 Previously it returned a float.
6457
Antoine Pitroub52ec782009-01-25 16:34:23 +00006458- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6459 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6460 evaluation loop is compiled with a new dispatch mechanism which gives
6461 speedups of up to 20%, depending on the system, on various benchmarks.
6462
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006463- Issue #4874: Most builtin decoders now reject unicode input.

6471 optional module state data.
6472
Mark Dickinson8055afd2009-01-17 10:04:45 +00006473- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006474 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006475
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006476- Issue #4935: The overflow checking code in the expandtabs() method common
6477 to str, bytes and bytearray could be optimized away by the compiler, letting
6478 the interpreter segfault instead of raising an error.
6479
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006480- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6481 __next__ method.
6482
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006483- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6484 function no longer attempt to call the __long__ slot to convert an object
6485 to an integer. Only the __int__ and __trunc__ slots are examined.
6486
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006487- Issue #4893: Use NT threading on CE.
6488

6490
Antoine Pitrouab868312009-01-10 15:40:25 +00006491- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6492 common cases are optimized thanks to a dedicated fast path and a moderate
6493 amount of loop unrolling.
6494
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006495- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6496 collecting the oldest generation) so that allocating lots of objects without
6497 destroying them does not show quadratic performance. Based on a proposal by
6498 Martin von Löwis at
6499 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6500
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006501- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006502 having been closed (for instance, a read() call could return some
6503 previously buffered data). Patch by Dmitry Vasiliev.
6504
Antoine Pitrou05608432009-01-09 18:53:14 +00006505- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6506 flag to work properly. Furthermore, when specifying -u, the text stdout
6507 and stderr streams have line-by-line buffering enabled (the default being
6508 to buffer arbitrary chunks of data).
6509
Raymond Hettinger35631532009-01-09 03:58:09 +00006510- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6511 instead of ints (reducing its size from 4 to 8 times thereby reducing
6512 Python's overall memory).
6513
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006514- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6515 an existing .py counterpart, override the co_filename attributes of all
6516 code objects if the original filename is obsolete (which can happen if the
6517 file has been renamed, moved, or if it is accessed through different paths).
6518 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6519
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006520- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6521 one byte. Also fixes the meaning of len() so that it returns the number of
6522 items, rather than the size in bytes.
6523
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006524- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6525
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006526- Issue #4747: When the terminal does not use utf-8, executing a script with
6527 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6528
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006529- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6530 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006531
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006532- Issue #3680: Reference cycles created through a dict, set or deque iterator
6533 did not get collected.
6534
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006535- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6536 where the tp_hash and tp_dict slots are both NULL.
6537
Georg Brandlccc47b62008-12-28 11:44:14 +00006538- Issue #4759: None is now allowed as the first argument of
6539 bytearray.translate(). It was always allowed for bytes.translate().
6540
Skip Montanaro80072cb2008-12-23 03:51:14 +00006541- Added test case to ensure attempts to read from a file opened for writing
6542 fail.
6543
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006544- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00006546- Issue #2183: Simplify and optimize bytecode for list, dict and set
6547 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6548
Antoine Pitrou621601a2008-12-17 23:18:19 +00006549- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6550 print elapsed times, not only when some objects are uncollectable /
6551 unreachable. Original patch by Neil Schemenauer.
6552
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006553- Issue #3439: Add a bit_length method to int.
6554
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006555- Issue #2173: When getting device encoding, check that return value of
6556 nl_langinfo is not the empty string. This was causing silent build
6557 failures on OS X.
6558
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006559- Issue #4597: Fixed several opcodes that weren't always propagating
6560 exceptions.
6561
6562- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006563 context manager returns a value that cannot be converted to a bool.
6564
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006565- Issue #4445: Replace "sizeof(PyBytesObject)" with
6566 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6567 bytes instances. On a typical machine this saves 3 bytes of memory
6568 (on average) per allocation of a bytes instance.
6569
Christian Heimesa872de52008-12-05 08:26:55 +00006570- Issue #4533: File read operation was dreadfully slow due to a slowly
6571 growing read buffer. Fixed by using the same growth rate algorithm as
6572 Python 2.x.
6573
Antoine Pitrou5504e892008-12-06 21:27:53 +00006574- Issue #4509: Various issues surrounding resize of bytearray objects to
6575 which there are buffer exports (e.g. memoryview instances).
6576
Georg Brandlf9734072008-12-07 15:30:06 +00006577- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6578 method on file objects with closefd=False. The file descriptor is still
6579 kept open but the file object behaves like a closed file. The ``FileIO``
6580 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006581
Antoine Pitroubc420402008-12-07 20:14:49 +00006582- Issue #4569: Interpreter crash when mutating a memoryview with an item size

6588
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006589- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6590 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6591 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6592 of using the replace error handler in PyUnicode_DecodeUTF8().
