710 and was unreliable since tests or user programs could modify the interpreter
711 environment after Distutils set it. Instead, have Distutils set the the
712 deployment target only in the environment of each build subprocess. It is
713 still possible to globally override the default by setting
714 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
715 greater or equal to the default value, the value with which the interpreter
716 was built.

1448
Armin Ronacher8d96d772011-01-22 13:13:05 +00001449- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1450 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1451 of HTTP 1.1.
1452
Armin Ronacher59531282011-01-22 13:44:22 +00001453- To match the behaviour of HTTP server, the HTTP client library now also
1454 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1455 that for incoming headers which makes this behaviour now consistent in
1456 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001556- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001557 continuation line in the formatted value has no leading white space and looks
1558 like a header. Since Generator uses Header to format all headers, this check
1559 is made for all headers in any serialized message at serialization time. This
1560 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001561

Éric Araujof0ab5d62011-05-29 03:43:59 +02001569 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001570 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001571
Éric Araujof0ab5d62011-05-29 03:43:59 +02001572- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001573 rfc2047-encoding header values with embedded newlines, leaving them without
1574 folding whitespace. It now uses the continuation_ws, as it does for
1575 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001577- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1578 time.asctime(), time.ctime() and time.strftime() functions will now format
1579 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1580 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1581 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1582 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

1592
Antoine Pitrou600232b2011-01-05 21:03:42 +00001593- Issue #7995: When calling accept() on a socket with a timeout, the returned

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002559- Issue #10068: Global objects which have reference cycles with their module's
2560 dict are now cleared again. This causes issue #7140 to appear again.
2561
Victor Stinner257d38f2010-10-09 10:12:11 +00002562- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002565- ast.literal_eval() can now handle negative numbers. It is also a little more
2566 liberal in what it accepts without compromising the safety of the evaluation.
2567 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00002574- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002575 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002589- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002590 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002594- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2595 threads are still running. Instead, reinitialize the GIL on a second call to
2596 Py_Initialize().
2597
Georg Brandl27a28582010-10-10 09:49:21 +00002598- All SyntaxErrors now have a column offset and therefore a caret when the error
2599 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00002601- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2602 module that was imported, but instead gets the module from sys.modules.
2603
Nick Coghlan37ee8502010-12-03 14:26:13 +00002604- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002607- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2608 with a non-empty format string. This is an effort to future-proof user
2609 code. If a derived class does not currently implement __format__ but later
2610 adds its own __format__, it would most likely break user code that had
2611 supplied a format string. This will be changed to a DeprecationWaring in
2612 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002613
Antoine Pitrou1df15362010-09-13 14:16:46 +00002614- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2615 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2616 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2617
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002618- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2619 functions from the libc caused the methods .upper() and lower() to become
2620 locale aware and created subtly wrong results.
2621
Georg Brandl27a28582010-10-10 09:49:21 +00002622- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2623 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002624
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002625- Issue #4617: Previously it was illegal to delete a name from the local
2626 namespace if it occurs as a free variable in a nested block. This limitation
2627 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2628
Georg Brandl27a28582010-10-10 09:49:21 +00002629- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2630 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2631 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2632 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002633
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002634- Issue #9757: memoryview objects get a release() method to release the
2635 underlying buffer (previously this was only done when deallocating the
2636 memoryview), and gain support for the context management protocol.
2637
Antoine Pitrou079ce542010-09-08 12:37:10 +00002638- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2639 thread-local storage key.

Éric Araujoef777bd2010-10-05 00:04:20 +00002667- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002668 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002669 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002670 replacement for old handle_accept() and avoids the user to call accept()
2671 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002702 received. Now sendall() properly calls signal handlers if necessary, and
2703 retries sending if these returned successfully, including on sockets with a
2704 timeout.

Georg Brandl27a28582010-10-10 09:49:21 +00002744 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002777- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002778 it possible for the user to create self-referencing ordered dictionaries which
2779 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002780 approach of using weakref proxies so that reference cycles never get created
2781 in the first place.

2789 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2790 reencode all filenames in all objects.

2801
Georg Brandl27a28582010-10-10 09:49:21 +00002802- Issue #9707: Rewritten reference implementation of threading.local which is
2803 friendlier towards reference cycles. This change is not normally visible

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002806- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2807 still return the id of the parent process after it has exited. This process
2808 id may even have been reused by another unrelated process.
2809
Georg Brandl27a28582010-10-10 09:49:21 +00002810- Issue #9792: In case of connection failure, socket.create_connection() would

2812 original errno, or to filter timeout errors. Now the original error is
2813 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002815- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2816 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2817 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002819- Updates to the random module:
2820
Georg Brandl27a28582010-10-10 09:49:21 +00002821 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002824 * Update the seed() method to use all of the bits in a string instead of just
2825 the hash value. This makes better use of the seed value and assures the
2826 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002828 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2829 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2830 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002831
2832 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002851- hashlib has two new constant attributes: algorithms_guaranteed and
2852 algorithms_avaiable that respectively list the names of hash algorithms
2853 guaranteed to exist in all Python implementations and the names of hash
2854 algorithms available in the current process.

Georg Brandl62069d32010-07-31 08:56:11 +00003415- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3416 TypeError instead of giving a DeprecationWarning when a float is parsed using
3417 the 'L' code (for long long). (All other integer codes already raise
3418 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00003428 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003429 like bytearray.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003444- Issue #8748: Fix two issues with comparisons between complex and integer
3445 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003446 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3447 (2) The comparison raised an OverflowError for large integers, leading to
3448 unpredictable exceptions when combining integers and complex objects in sets
3449 or dicts.

3472
Victor Stinner0964ee12010-04-30 16:48:45 +00003473- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

Georg Brandl62069d32010-07-31 08:56:11 +00003637- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
3638 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
3639 long but the length of the range did not. Also fix several cases where
3640 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
3641 reversed(range(a, b, c)) with large arguments.

3753 `va_copy`, but available on all python platforms.
3754
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003755- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3756 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3779 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3780 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003781 to match the behaviour of the other integer format codes.

3809 allocator will be automatically disabled when running under Valgrind. This
3810 gives improved memory leak detection when running under Valgrind, while taking
3811 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003884- The default size of the re module's compiled regular expression cache has been
3885 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003886 simply clearing the entire cache on overflow to forgetting the least recently
3887 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003888 applications that use a lot of regular expressions and limits the impact of
3889 the performance hit anytime the cache is exceeded.

3902 module is renamed to `_datetime` and if available, overrides all classes
3903 defined in datetime with fast C impementation. Python implementation is based

4134
Victor Stinnerd17f2192010-08-15 09:56:07 +00004135- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00004136 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00004143- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4144 operation raises multiple signals and more than one of those signals is
4145 trapped, the specification determines the order in which the signals should be
4146 handled. In many cases this order wasn't being followed, leading to the wrong
4147 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00004148
Antoine Pitrou6be88762010-05-03 16:48:20 +00004149- Issue #7865: The close() method of :mod:`io` objects should not swallow

Georg Brandl62069d32010-07-31 08:56:11 +00004181- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4182 the method could block indefinitely if called just before the event loop
4183 started running. This also fixes the occasional freezes witnessed in

Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00004185
Georg Brandl62069d32010-07-31 08:56:11 +00004186- Issue #8524: When creating an SSL socket, the timeout value of the original
4187 socket wasn't retained (instead, a socket with a positive timeout would be
4188 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004189
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004190- Issue #5103: SSL handshake would ignore the socket timeout and block
4191 indefinitely if the other end didn't respond.
4192
Georg Brandl62069d32010-07-31 08:56:11 +00004193- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004205- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4206 string "python" as the *ident*. openlog() arguments are all optional and
4207 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004208
Georg Brandl62069d32010-07-31 08:56:11 +00004209- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4210 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004211 wanting to continue using the socket in clear-text mode, by disabling
4212 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004262 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004263 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004264

R. David Murrayb2416e52010-04-12 16:58:02 +00004269- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004270 filename and date, conforming to the 'standards' they were originally designed
4271 to follow. This improves compatibility with patch tools.

Georg Brandl62069d32010-07-31 08:56:11 +00004298- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4299 InvalidOperation instead of returning False. (Comparisons involving a quiet
4300 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4301 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004302
Georg Brandl62069d32010-07-31 08:56:11 +00004303- Issue #2531: Comparison operations between floats and Decimal instances now
4304 return a result based on the numeric values of the operands; previously they
4305 returned an arbitrary result based on the relative ordering of id(float) and
4306 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4307 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004308
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004309- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004311- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004312 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandl62069d32010-07-31 08:56:11 +00004320- Comparisons using one of <, <=, >, >= between a complex instance and a
4321 Fractions instance now raise TypeError instead of returning True/False. This
4322 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4323 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00004332- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004333 didn't support chflags() (for example ZFS under FreeBSD). The error is now

4367 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4368 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004369
Georg Brandl62069d32010-07-31 08:56:11 +00004370- subprocess.Popen now has restore_signals and start_new_session features. The
4371 default of restore_signals=True is a new behavior compared to earlier Python
4372 versions. This means that signals such as SIGPIPE are not ignored by default
4373 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004374

Georg Brandl62069d32010-07-31 08:56:11 +00004459- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4460 position when calling `truncate()`. It would previously change the file
4461 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004462 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4463
Antoine Pitroua32f9a22010-01-27 21:18:57 +00004464- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004465 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4466 archive. The new implementation is significantly faster and can be wrapped in
4467 a :class:`io.BufferedReader` object for more speedups. It also solves an
4468 issue where interleaved calls to `read()` and `readline()` give wrong results.
4469 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004804- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004805 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4806 PyPycLoader inherit from this class and provide implementations in relation to
4807 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004808
Brett Cannon64ef00f2009-07-20 03:19:18 +00004809- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4810 the documentation said it did even though the code in PyLoader relied on the
4811 abstract method required by ResourceLoader.
4812
Georg Brandl62069d32010-07-31 08:56:11 +00004813- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004861- Issue #9959: Tweak formula used for computing math.log of an integer,
4862 making it marginally more accurate for exact powers of 2.
4863
Mark Dickinsoncf28b952010-07-29 21:41:59 +00004864- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4865
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004866- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004867 compared to other unix systems. In particular, os.getgroups() does not reflect
4868 any changes made using os.setgroups() but basicly always returns the same
4869 information as the id command. os.getgroups() can now return more than 16
4870 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004871
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00004872- Issue #6095: Make directory argument to os.listdir optional.

4875 struct.pack('>?')): if conversion to bool raised an exception then that
4876 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00004877
Georg Brandl62069d32010-07-31 08:56:11 +00004878- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
4879 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00004880
Georg Brandl62069d32010-07-31 08:56:11 +00004881- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany

4891
Benjamin Petersonf751bc92010-07-02 13:46:42 +00004892- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
4893 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00004894
Georg Brandl62069d32010-07-31 08:56:11 +00004895- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4896 Prior to this change, timezone adjustment in utctimetuple() could produce
4897 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4898 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00004899
Georg Brandl62069d32010-07-31 08:56:11 +00004900- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4901 directive. When the ``%z`` directive is present in the format string, an
4902 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4903 ``datetime.timezone`` instance constructed from the parsed offset. If both
4904 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4905 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004906
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004907- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004908 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4909 ``datetime.timezone``, return fixed name and UTC offset from their
4910 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4911 returns ``None``. A class attribute, ``utc`` contains an instance
4912 representing the UTC timezone. Original patch by Rafe Kaplan.

4923 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00004924

Georg Brandl62069d32010-07-31 08:56:11 +00004928- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4929 with an improved 'binary-split' algorithm that uses fewer multiplications and
4930 allows many of the multiplications to be performed using plain C integer
4931 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4932 arguments.

4936
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004937- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4938 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004939 the result is now always correctly rounded, and is equivalent to ``td /
4940 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004941
Georg Brandl62069d32010-07-31 08:56:11 +00004942- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

Mark Dickinsonc5935772010-04-03 15:54:36 +00004948- Issue #8300: When passing a non-integer argument to struct.pack with any
4949 integer format code, struct.pack first attempts to convert the non-integer
4950 using its __index__ method. If that method is non-existent or raises
4951 TypeError it goes on to try the __int__ method, as described below.
4952

Eric Smith63376222009-05-05 14:04:18 +00005529- Issue #5920: For float.__format__, change the behavior with the

5531 to be like 'g' but with at least one decimal point and with a
5532 default precision of 12. Previously, the behavior the same but with
5533 a default precision of 6. This more closely matches str(), and
5534 reduces surprises when adding alignment flags to the empty
5535 presentation type. This also affects the new complex.__format__ in
5536 the same way.
5537
Martin v. Löwis011e8422009-05-05 04:43:17 +00005538- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

5550 received a new method, detach(). detach() disconnects the underlying stream
5551 from the buffer or text IO and returns it.
5552
Mark Dickinson33841c32009-05-01 15:37:04 +00005553- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5554 floats with absolute value over 1e50. Also remove length
5555 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005579- Issue #1869 (and many duplicates): make round(x, n) correctly
5580 rounded for a float x, by using the decimal <-> binary conversions
5581 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5582 consistently agrees with format(x, '.2f').
5583
Benjamin Petersonae937c02009-04-18 20:54:08 +00005584- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00005587- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5588
Eric Smith35e84722009-04-16 20:21:28 +00005589- Issue #5515: str.format() type 'n' combined with commas and leading
5590 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005591
5592- Implement PEP 378, Format Specifier for Thousands Separator, for
5593 floats.
5594
Mark Dickinson3370cce2009-04-17 22:40:53 +00005595- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005596 1e11, not 1e12. This avoids printing 13 significant digits in
5597 situations where only 12 of them are correct. Example problem
5598 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5599 long time.)
5600
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005601- Issue #1580: On most platforms, use a 'short' float repr: for a
5602 finite float x, repr(x) now outputs a string based on the shortest
5603 sequence of decimal digits that rounds to x. Previous behaviour was
5604 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005605 Another minor difference is that the new repr switches to
5606 exponential notation at 1e16 instead of the previous 1e17; this
5607 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005608
5609 There's a new sys attribute sys.float_repr_style, which takes
5610 the value 'short' to indicate that we're using short float repr,
5611 and 'legacy' if the short float repr isn't available for one
5612 reason or another.
5613
5614 The float repr change involves incorporating David Gay's 'perfect
5615 rounding' code into the Python core (it's in Python/dtoa.c). As a
5616 secondary consequence, all string-to-float and float-to-string
5617 conversions (including all float formatting operations) will be
5618 correctly rounded on these platforms.
5619
Georg Brandl5f90d792010-08-01 22:31:05 +00005620 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005621 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005623- Issue #5759: float() didn't call __float__ on str subclasses.
5624
Georg Brandlabc38772009-04-12 15:51:51 +00005625- The string.maketrans() function is deprecated; there is a new static method
5626 maketrans() on the bytes and bytearray classes. This removes confusion about
5627 the types string.maketrans() is supposed to work with, and mirrors the
5628 methods available on the str class.
5629
R. David Murraydc6da8a2009-04-09 22:16:43 +00005630- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5912
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005913- Issue #5249: time.strftime returned malformed string when format string
5914 contained non ascii character on windows.
5915
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005916- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

5920 rotating the object pointer by 4 bits to the right.
5921
Mark Dickinson87ec0852009-02-09 17:15:59 +00005922- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5923 it now forces its argument to double before testing for infinity.
5924
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005925- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5926 returns a non-number type.
5927
Benjamin Peterson87618552009-02-08 15:00:52 +00005928- Issue #5182: Removed memoryview.__str__.
5929
Mark Dickinsonc008a172009-02-01 13:59:22 +00005930- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5931 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005932 the type definition cmpfunc. The tp_compare slot has been renamed

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005934
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005935- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005936 were suppressing all exceptions. These include list() and bytearray().
5937
Mark Dickinson1124e712009-01-28 21:25:58 +00005938- Issue #4707: round(x, n) now returns an integer if x is an integer.
5939 Previously it returned a float.
5940
Antoine Pitroub52ec782009-01-25 16:34:23 +00005941- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5942 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5943 evaluation loop is compiled with a new dispatch mechanism which gives
5944 speedups of up to 20%, depending on the system, on various benchmarks.
5945
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005946- Issue #4874: Most builtin decoders now reject unicode input.

5954 optional module state data.
5955
Mark Dickinson8055afd2009-01-17 10:04:45 +00005956- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005957 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005958
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005959- Issue #4935: The overflow checking code in the expandtabs() method common
5960 to str, bytes and bytearray could be optimized away by the compiler, letting
5961 the interpreter segfault instead of raising an error.
5962
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005963- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5964 __next__ method.
5965
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005966- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5967 function no longer attempt to call the __long__ slot to convert an object
5968 to an integer. Only the __int__ and __trunc__ slots are examined.
5969
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005970- Issue #4893: Use NT threading on CE.
5971
Martin v. Löwisec59d042009-01-12 07:59:10 +00005972- Issue #4915: Port sysmodule to Windows CE.
5973
Antoine Pitrouab868312009-01-10 15:40:25 +00005974- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5975 common cases are optimized thanks to a dedicated fast path and a moderate
5976 amount of loop unrolling.
5977
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005978- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5979 collecting the oldest generation) so that allocating lots of objects without
5980 destroying them does not show quadratic performance. Based on a proposal by
5981 Martin von Löwis at
5982 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5983
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005984- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005985 having been closed (for instance, a read() call could return some
5986 previously buffered data). Patch by Dmitry Vasiliev.
5987
Antoine Pitrou05608432009-01-09 18:53:14 +00005988- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5989 flag to work properly. Furthermore, when specifying -u, the text stdout
5990 and stderr streams have line-by-line buffering enabled (the default being
5991 to buffer arbitrary chunks of data).
5992
Raymond Hettinger35631532009-01-09 03:58:09 +00005993- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5994 instead of ints (reducing its size from 4 to 8 times thereby reducing
5995 Python's overall memory).
5996
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005997- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5998 an existing .py counterpart, override the co_filename attributes of all
5999 code objects if the original filename is obsolete (which can happen if the
6000 file has been renamed, moved, or if it is accessed through different paths).
6001 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6002
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006003- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6004 one byte. Also fixes the meaning of len() so that it returns the number of
6005 items, rather than the size in bytes.
6006
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006007- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6008
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006009- Issue #4747: When the terminal does not use utf-8, executing a script with
6010 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6011
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006012- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6013 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006014
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006015- Issue #3680: Reference cycles created through a dict, set or deque iterator
6016 did not get collected.
6017
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006018- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6019 where the tp_hash and tp_dict slots are both NULL.
6020
Georg Brandlccc47b62008-12-28 11:44:14 +00006021- Issue #4759: None is now allowed as the first argument of
6022 bytearray.translate(). It was always allowed for bytes.translate().
6023
Skip Montanaro80072cb2008-12-23 03:51:14 +00006024- Added test case to ensure attempts to read from a file opened for writing
6025 fail.
6026
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006027- Issue #3106: Speedup some comparisons (str/str and int/int).

6030 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6031
Antoine Pitrou621601a2008-12-17 23:18:19 +00006032- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6033 print elapsed times, not only when some objects are uncollectable /
6034 unreachable. Original patch by Neil Schemenauer.
6035
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006036- Issue #3439: Add a bit_length method to int.
6037
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006038- Issue #2173: When getting device encoding, check that return value of
6039 nl_langinfo is not the empty string. This was causing silent build
6040 failures on OS X.
6041
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006042- Issue #4597: Fixed several opcodes that weren't always propagating
6043 exceptions.
6044
6045- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006046 context manager returns a value that cannot be converted to a bool.
6047
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006048- Issue #4445: Replace "sizeof(PyBytesObject)" with
6049 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6050 bytes instances. On a typical machine this saves 3 bytes of memory
6051 (on average) per allocation of a bytes instance.
6052
Christian Heimesa872de52008-12-05 08:26:55 +00006053- Issue #4533: File read operation was dreadfully slow due to a slowly
6054 growing read buffer. Fixed by using the same growth rate algorithm as
6055 Python 2.x.
6056
Antoine Pitrou5504e892008-12-06 21:27:53 +00006057- Issue #4509: Various issues surrounding resize of bytearray objects to
6058 which there are buffer exports (e.g. memoryview instances).
6059
Georg Brandlf9734072008-12-07 15:30:06 +00006060- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6061 method on file objects with closefd=False. The file descriptor is still
6062 kept open but the file object behaves like a closed file. The ``FileIO``
6063 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006064
Antoine Pitroubc420402008-12-07 20:14:49 +00006065- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6066 larger than 1.

6071
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006072- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6073 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6074 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6075 of using the replace error handler in PyUnicode_DecodeUTF8().
