Ned Deily657b2de2011-06-28 19:51:30 -0700779- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
780 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
781 interpreter process. This could cause failures in non-Distutils subprocesses
782 and was unreliable since tests or user programs could modify the interpreter
783 environment after Distutils set it. Instead, have Distutils set the the
784 deployment target only in the environment of each build subprocess. It is
785 still possible to globally override the default by setting
786 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
787 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700788 was built. Also, implement the same handling in packaging.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00002029- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00002030 continuation line in the formatted value has no leading white space and looks
2031 like a header. Since Generator uses Header to format all headers, this check
2032 is made for all headers in any serialized message at serialization time. This
2033 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00002034
Antoine Pitrou67b212e2011-01-08 09:55:31 +00002035- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +00002041- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02002042 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00002043 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002044
Éric Araujof0ab5d62011-05-29 03:43:59 +02002045- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00002046 rfc2047-encoding header values with embedded newlines, leaving them without
2047 folding whitespace. It now uses the continuation_ws, as it does for
2048 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00002049
Victor Stinner3ec899f2011-01-08 16:37:47 +00002050- Issue #1777412, #10827: Changed the rules for 2-digit years. The
2051 time.asctime(), time.ctime() and time.strftime() functions will now format
2052 any year when ``time.accept2dyear`` is False and will accept years >= 1000
2053 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2054 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2055 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00002056
Antoine Pitroue85da7a2011-01-06 18:25:55 +00002057- Issue #7858: Raise an error properly when os.utime() fails under Windows

2065
Antoine Pitrou600232b2011-01-05 21:03:42 +00002066- Issue #7995: When calling accept() on a socket with a timeout, the returned

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00003036- Issue #10068: Global objects which have reference cycles with their module's
3037 dict are now cleared again. This causes issue #7140 to appear again.
3038
Victor Stinner257d38f2010-10-09 10:12:11 +00003039- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00003040 encodings.

Georg Brandl27a28582010-10-10 09:49:21 +00003042- ast.literal_eval() can now handle negative numbers. It is also a little more
3043 liberal in what it accepts without compromising the safety of the evaluation.
3044 For example, 3j+4 and 3+4+5 are both accepted.

3048
Victor Stinneraef57e32010-10-02 11:50:49 +00003049- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.

Victor Stinner5593d8a2010-10-02 11:11:27 +00003051- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00003052 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Brett Cannon5305a992010-09-27 21:08:38 +00003060- Issue #7397: Mention that importlib.import_module() is probably what someone

3062
Georg Brandl27a28582010-10-10 09:49:21 +00003063- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003066- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003067 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

3070
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003071- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3072 threads are still running. Instead, reinitialize the GIL on a second call to
3073 Py_Initialize().
3074
Georg Brandl27a28582010-10-10 09:49:21 +00003075- All SyntaxErrors now have a column offset and therefore a caret when the error
3076 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003077
Brett Cannonbc2eff32010-09-19 21:39:02 +00003078- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3079 module that was imported, but instead gets the module from sys.modules.
3080
Nick Coghlan37ee8502010-12-03 14:26:13 +00003081- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003082 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00003084- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3085 with a non-empty format string. This is an effort to future-proof user
3086 code. If a derived class does not currently implement __format__ but later
3087 adds its own __format__, it would most likely break user code that had
3088 supplied a format string. This will be changed to a DeprecationWaring in
3089 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003090
Antoine Pitrou1df15362010-09-13 14:16:46 +00003091- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3092 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3093 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3094
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003095- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3096 functions from the libc caused the methods .upper() and lower() to become
3097 locale aware and created subtly wrong results.
3098
Georg Brandl27a28582010-10-10 09:49:21 +00003099- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3100 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003101
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003102- Issue #4617: Previously it was illegal to delete a name from the local
3103 namespace if it occurs as a free variable in a nested block. This limitation
3104 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3105
Georg Brandl27a28582010-10-10 09:49:21 +00003106- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3107 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3108 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3109 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003110
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003111- Issue #9757: memoryview objects get a release() method to release the
3112 underlying buffer (previously this was only done when deallocating the
3113 memoryview), and gain support for the context management protocol.
3114
Antoine Pitrou079ce542010-09-08 12:37:10 +00003115- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3116 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00003132- Issue #4661: email can now parse bytes input and generate either converted

3134
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003135- Issue #1589: Add ssl.match_hostname(), to help implement server identity

3140
Éric Araujo6108bf52010-10-04 23:52:37 +00003141- Issue #9042: Fix interaction of custom translation classes and caching in
3142 gettext.
3143
Éric Araujoef777bd2010-10-05 00:04:20 +00003144- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003145 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003146 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003147 replacement for old handle_accept() and avoids the user to call accept()
3148 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003171- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003172 retry the select() loop instead of bailing out. This is because select() can
3173 incorrectly report a socket as ready for reading (for example, if it received
3174 some data with an invalid checksum).

3219
Antoine Pitrou98b46702010-09-18 22:59:00 +00003220- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003221 non-blocking mode: they return None when an operation would block (instead of
3222 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00003223
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00003224- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003254- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003255 it possible for the user to create self-referencing ordered dictionaries which
3256 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003257 approach of using weakref proxies so that reference cycles never get created
3258 in the first place.
3259
Victor Stinnercb043522010-09-10 23:49:04 +00003260- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3261 encode the value with filesystem encoding and surrogateescape (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00003264- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3265 environment variable to set the filesystem encoding at Python startup.
3266 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3267 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003268
Georg Brandl27a28582010-10-10 09:49:21 +00003269- Issue #9410: Various optimizations to the pickle module, leading to speedups

3278
Georg Brandl27a28582010-10-10 09:49:21 +00003279- Issue #9707: Rewritten reference implementation of threading.local which is
3280 friendlier towards reference cycles. This change is not normally visible
3281 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003282
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003283- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3284 still return the id of the parent process after it has exited. This process
3285 id may even have been reused by another unrelated process.
3286
Georg Brandl27a28582010-10-10 09:49:21 +00003287- Issue #9792: In case of connection failure, socket.create_connection() would
3288 swallow the exception and raise a new one, making it impossible to fetch the
3289 original errno, or to filter timeout errors. Now the original error is
3290 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00003291
Georg Brandl27a28582010-10-10 09:49:21 +00003292- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3293 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3294 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003295
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003296- Updates to the random module:
3297
Georg Brandl27a28582010-10-10 09:49:21 +00003298 * Document which parts of the module are guaranteed to stay the same across
3299 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003301 * Update the seed() method to use all of the bits in a string instead of just
3302 the hash value. This makes better use of the seed value and assures the
3303 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003304
Georg Brandl27a28582010-10-10 09:49:21 +00003305 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3306 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3307 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003308
3309 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003328- hashlib has two new constant attributes: algorithms_guaranteed and
3329 algorithms_avaiable that respectively list the names of hash algorithms
3330 guaranteed to exist in all Python implementations and the names of hash
3331 algorithms available in the current process.
3332

Ezio Melotti57221d02010-07-01 07:32:02 +00003843- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003844 start byte and the continuation byte(s) are now considered invalid, instead of
3845 the number of bytes specified by the start byte. E.g.:
3846 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3847 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3848 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3849 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003879- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003880 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

3893 TypeError instead of giving a DeprecationWarning when a float is parsed using
3894 the 'L' code (for long long). (All other integer codes already raise
3895 TypeError in this case.)

3900
Georg Brandl62069d32010-07-31 08:56:11 +00003901- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003903

Georg Brandl62069d32010-07-31 08:56:11 +00003905 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

3907
Georg Brandl62069d32010-07-31 08:56:11 +00003908- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

3922 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003923 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004228- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

4230 `va_copy`, but available on all python platforms.
4231
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004232- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4233 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4234 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00004244- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00004245 function declaration, which was kept for backwards compatibility reasons, is
4246 now removed (the macro was introduced in 1997!).

4256 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4257 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004258 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004268- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4269 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4270 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00004285- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4286 allocator will be automatically disabled when running under Valgrind. This
4287 gives improved memory leak detection when running under Valgrind, while taking
4288 advantage of pymalloc at other times.

4364 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004365 applications that use a lot of regular expressions and limits the impact of

4379 module is renamed to `_datetime` and if available, overrides all classes
4380 defined in datetime with fast C impementation. Python implementation is based
4381 on the original python prototype for the datetime module by Tim Peters with
4382 minor modifications by the PyPy project. The test suite now tests `datetime`
4383 module with and without `_datetime` acceleration using the same test cases.

Benjamin Peterson225168e2010-05-06 22:29:53 +00004597- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
4598 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
4599 file system encoding with the surrogateescape error handler (instead of
4600 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Georg Brandl62069d32010-07-31 08:56:11 +00004620- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4621 operation raises multiple signals and more than one of those signals is
4622 trapped, the specification determines the order in which the signals should be
4623 handled. In many cases this order wasn't being followed, leading to the wrong
4624 Python exception being raised.

4664 socket wasn't retained (instead, a socket with a positive timeout would be
4665 turned into a non-blocking SSL socket).

Georg Brandl62069d32010-07-31 08:56:11 +00004780- Issue #2531: Comparison operations between floats and Decimal instances now
4781 return a result based on the numeric values of the operands; previously they
4782 returned an arbitrary result based on the relative ordering of id(float) and

4799 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4800 <=> complex, and complex <=> complex comparisons.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005343- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005344 compared to other unix systems. In particular, os.getgroups() does not reflect
5345 any changes made using os.setgroups() but basicly always returns the same
5346 information as the id command. os.getgroups() can now return more than 16
5347 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005372- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5373 Prior to this change, timezone adjustment in utctimetuple() could produce
5374 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5378 directive. When the ``%z`` directive is present in the format string, an
5379 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5380 ``datetime.timezone`` instance constructed from the parsed offset. If both
5381 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5382 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005385 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5386 ``datetime.timezone``, return fixed name and UTC offset from their
5387 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5388 returns ``None``. A class attribute, ``utc`` contains an instance
5389 representing the UTC timezone. Original patch by Rafe Kaplan.

5406 with an improved 'binary-split' algorithm that uses fewer multiplications and
5407 allows many of the multiplications to be performed using plain C integer
5408 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005414- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5415 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005416 the result is now always correctly rounded, and is equivalent to ``td /
5417 timedelta(seconds=1)``.

5426 integer format code, struct.pack first attempts to convert the non-integer
5427 using its __index__ method. If that method is non-existent or raises
5428 TypeError it goes on to try the __int__ method, as described below.

Antoine Pitrou716c4442009-05-23 19:04:03 +00005917- Issue #5761: Add the name of the underlying file to the repr() of various

6005
Eric Smith63376222009-05-05 14:04:18 +00006006- Issue #5920: For float.__format__, change the behavior with the
6007 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6008 to be like 'g' but with at least one decimal point and with a
6009 default precision of 12. Previously, the behavior the same but with
6010 a default precision of 6. This more closely matches str(), and
6011 reduces surprises when adding alignment flags to the empty
6012 presentation type. This also affects the new complex.__format__ in
6013 the same way.
6014
Martin v. Löwis011e8422009-05-05 04:43:17 +00006015- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00006026- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6027 received a new method, detach(). detach() disconnects the underlying stream
6028 from the buffer or text IO and returns it.
6029
Mark Dickinson33841c32009-05-01 15:37:04 +00006030- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6031 floats with absolute value over 1e50. Also remove length
6032 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

6039 never gives more than the requested number of significant digits.
6040
Eric Smith6dc46f52009-04-27 20:39:49 +00006041- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00006056- Issue #1869 (and many duplicates): make round(x, n) correctly
6057 rounded for a float x, by using the decimal <-> binary conversions
6058 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6059 consistently agrees with format(x, '.2f').
6060
Benjamin Petersonae937c02009-04-18 20:54:08 +00006061- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6062 some builtin types.

Eric Smith0923d1d2009-04-16 20:16:10 +00006064- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6065
Eric Smith35e84722009-04-16 20:21:28 +00006066- Issue #5515: str.format() type 'n' combined with commas and leading
6067 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006068
6069- Implement PEP 378, Format Specifier for Thousands Separator, for
6070 floats.
6071
Mark Dickinson3370cce2009-04-17 22:40:53 +00006072- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006073 1e11, not 1e12. This avoids printing 13 significant digits in
6074 situations where only 12 of them are correct. Example problem
6075 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6076 long time.)
6077
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006078- Issue #1580: On most platforms, use a 'short' float repr: for a
6079 finite float x, repr(x) now outputs a string based on the shortest
6080 sequence of decimal digits that rounds to x. Previous behaviour was
6081 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006082 Another minor difference is that the new repr switches to
6083 exponential notation at 1e16 instead of the previous 1e17; this
6084 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006085
6086 There's a new sys attribute sys.float_repr_style, which takes
6087 the value 'short' to indicate that we're using short float repr,
6088 and 'legacy' if the short float repr isn't available for one
6089 reason or another.
6090
6091 The float repr change involves incorporating David Gay's 'perfect
6092 rounding' code into the Python core (it's in Python/dtoa.c). As a
6093 secondary consequence, all string-to-float and float-to-string
6094 conversions (including all float formatting operations) will be
6095 correctly rounded on these platforms.
6096
Georg Brandl5f90d792010-08-01 22:31:05 +00006097 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006098 this change does not apply.
6099
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006100- Issue #5759: float() didn't call __float__ on str subclasses.
6101
Georg Brandlabc38772009-04-12 15:51:51 +00006102- The string.maketrans() function is deprecated; there is a new static method
6103 maketrans() on the bytes and bytearray classes. This removes confusion about
6104 the types string.maketrans() is supposed to work with, and mirrors the
6105 methods available on the str class.
6106
R. David Murraydc6da8a2009-04-09 22:16:43 +00006107- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6108 its clarity and its speed.
6109
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006110- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``

6112
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006113- Issue #3739: The unicode-internal encoder now reports the number of characters

6274 untrackable objects are not tracked by the garbage collector. This can
6275 reduce the size of collections and therefore the garbage collection overhead
6276 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00006368- Issue #5463: In struct module, remove deprecated overflow wrapping
6369 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006370 struct.error instead of returning b'\xff\xff\xff\xff'. The
6371 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6372 have been removed from the struct module.

6389
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006390- Issue #5249: time.strftime returned malformed string when format string
6391 contained non ascii character on windows.
6392
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006393- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

6395
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006396- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6397 rotating the object pointer by 4 bits to the right.
6398
Mark Dickinson87ec0852009-02-09 17:15:59 +00006399- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6400 it now forces its argument to double before testing for infinity.
6401
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006402- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6403 returns a non-number type.
6404
Benjamin Peterson87618552009-02-08 15:00:52 +00006405- Issue #5182: Removed memoryview.__str__.

6410 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006411
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006412- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006413 were suppressing all exceptions. These include list() and bytearray().
6414
Mark Dickinson1124e712009-01-28 21:25:58 +00006415- Issue #4707: round(x, n) now returns an integer if x is an integer.
6416 Previously it returned a float.
6417
Antoine Pitroub52ec782009-01-25 16:34:23 +00006418- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6419 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6420 evaluation loop is compiled with a new dispatch mechanism which gives
6421 speedups of up to 20%, depending on the system, on various benchmarks.
6422
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006423- Issue #4874: Most builtin decoders now reject unicode input.

6429
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006430- Issue #4838: When a module is deallocated, free the memory backing the
6431 optional module state data.
6432
Mark Dickinson8055afd2009-01-17 10:04:45 +00006433- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006434 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006435
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006436- Issue #4935: The overflow checking code in the expandtabs() method common
6437 to str, bytes and bytearray could be optimized away by the compiler, letting
6438 the interpreter segfault instead of raising an error.
6439
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006440- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6441 __next__ method.
6442
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006443- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6444 function no longer attempt to call the __long__ slot to convert an object
6445 to an integer. Only the __int__ and __trunc__ slots are examined.
6446
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006447- Issue #4893: Use NT threading on CE.
6448

6450
Antoine Pitrouab868312009-01-10 15:40:25 +00006451- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6452 common cases are optimized thanks to a dedicated fast path and a moderate
6453 amount of loop unrolling.
6454
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006455- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6456 collecting the oldest generation) so that allocating lots of objects without
6457 destroying them does not show quadratic performance. Based on a proposal by
6458 Martin von Löwis at
6459 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6460
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006461- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006462 having been closed (for instance, a read() call could return some
6463 previously buffered data). Patch by Dmitry Vasiliev.
6464
Antoine Pitrou05608432009-01-09 18:53:14 +00006465- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6466 flag to work properly. Furthermore, when specifying -u, the text stdout
6467 and stderr streams have line-by-line buffering enabled (the default being
6468 to buffer arbitrary chunks of data).
6469
Raymond Hettinger35631532009-01-09 03:58:09 +00006470- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6471 instead of ints (reducing its size from 4 to 8 times thereby reducing
6472 Python's overall memory).
6473
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006474- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6475 an existing .py counterpart, override the co_filename attributes of all
6476 code objects if the original filename is obsolete (which can happen if the
6477 file has been renamed, moved, or if it is accessed through different paths).
6478 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6479
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006480- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6481 one byte. Also fixes the meaning of len() so that it returns the number of
6482 items, rather than the size in bytes.
6483
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006484- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6485
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006486- Issue #4747: When the terminal does not use utf-8, executing a script with
6487 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6488
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006489- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6490 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006491
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006492- Issue #3680: Reference cycles created through a dict, set or deque iterator
6493 did not get collected.
6494
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006495- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6496 where the tp_hash and tp_dict slots are both NULL.
6497
Georg Brandlccc47b62008-12-28 11:44:14 +00006498- Issue #4759: None is now allowed as the first argument of
6499 bytearray.translate(). It was always allowed for bytes.translate().
6500
Skip Montanaro80072cb2008-12-23 03:51:14 +00006501- Added test case to ensure attempts to read from a file opened for writing
6502 fail.
6503
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006504- Issue #3106: Speedup some comparisons (str/str and int/int).

6508
Antoine Pitrou621601a2008-12-17 23:18:19 +00006509- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6510 print elapsed times, not only when some objects are uncollectable /
6511 unreachable. Original patch by Neil Schemenauer.
6512
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006513- Issue #3439: Add a bit_length method to int.
6514
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006515- Issue #2173: When getting device encoding, check that return value of
6516 nl_langinfo is not the empty string. This was causing silent build
6517 failures on OS X.
6518
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006519- Issue #4597: Fixed several opcodes that weren't always propagating
6520 exceptions.
6521
6522- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006523 context manager returns a value that cannot be converted to a bool.
6524
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006525- Issue #4445: Replace "sizeof(PyBytesObject)" with
6526 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6527 bytes instances. On a typical machine this saves 3 bytes of memory
6528 (on average) per allocation of a bytes instance.
6529
Christian Heimesa872de52008-12-05 08:26:55 +00006530- Issue #4533: File read operation was dreadfully slow due to a slowly
6531 growing read buffer. Fixed by using the same growth rate algorithm as
6532 Python 2.x.
6533
Antoine Pitrou5504e892008-12-06 21:27:53 +00006534- Issue #4509: Various issues surrounding resize of bytearray objects to
6535 which there are buffer exports (e.g. memoryview instances).
6536
Georg Brandlf9734072008-12-07 15:30:06 +00006537- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6538 method on file objects with closefd=False. The file descriptor is still
6539 kept open but the file object behaves like a closed file. The ``FileIO``
6540 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006541
Antoine Pitroubc420402008-12-07 20:14:49 +00006542- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6543 larger than 1.
6544

6548
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006549- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6550 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6551 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6552 of using the replace error handler in PyUnicode_DecodeUTF8().
