412 still possible to globally override the default by setting

415 was built.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001255- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001256 continuation line in the formatted value has no leading white space and looks
1257 like a header. Since Generator uses Header to format all headers, this check
1258 is made for all headers in any serialized message at serialization time. This
1259 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001260

Éric Araujof0ab5d62011-05-29 03:43:59 +02001268 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001269 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001270
Éric Araujof0ab5d62011-05-29 03:43:59 +02001271- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001272 rfc2047-encoding header values with embedded newlines, leaving them without
1273 folding whitespace. It now uses the continuation_ws, as it does for
1274 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001276- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1277 time.asctime(), time.ctime() and time.strftime() functions will now format

1279 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1280 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1281 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002258- Issue #10068: Global objects which have reference cycles with their module's
2259 dict are now cleared again. This causes issue #7140 to appear again.
2260
Victor Stinner257d38f2010-10-09 10:12:11 +00002261- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002264- ast.literal_eval() can now handle negative numbers. It is also a little more
2265 liberal in what it accepts without compromising the safety of the evaluation.
2266 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00002273- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002274 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002288- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002289 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

2292
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002293- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2294 threads are still running. Instead, reinitialize the GIL on a second call to
2295 Py_Initialize().
2296
Georg Brandl27a28582010-10-10 09:49:21 +00002297- All SyntaxErrors now have a column offset and therefore a caret when the error
2298 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002299
Brett Cannonbc2eff32010-09-19 21:39:02 +00002300- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2301 module that was imported, but instead gets the module from sys.modules.
2302
Nick Coghlan37ee8502010-12-03 14:26:13 +00002303- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002304 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00002306- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2307 with a non-empty format string. This is an effort to future-proof user
2308 code. If a derived class does not currently implement __format__ but later
2309 adds its own __format__, it would most likely break user code that had
2310 supplied a format string. This will be changed to a DeprecationWaring in
2311 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002312
Antoine Pitrou1df15362010-09-13 14:16:46 +00002313- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2314 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2315 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2316
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002317- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2318 functions from the libc caused the methods .upper() and lower() to become
2319 locale aware and created subtly wrong results.
2320
Georg Brandl27a28582010-10-10 09:49:21 +00002321- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2322 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002323
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002324- Issue #4617: Previously it was illegal to delete a name from the local
2325 namespace if it occurs as a free variable in a nested block. This limitation
2326 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2327
Georg Brandl27a28582010-10-10 09:49:21 +00002328- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2329 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2330 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2331 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002332
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002333- Issue #9757: memoryview objects get a release() method to release the
2334 underlying buffer (previously this was only done when deallocating the
2335 memoryview), and gain support for the context management protocol.
2336
Antoine Pitrou079ce542010-09-08 12:37:10 +00002337- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2338 thread-local storage key.

Antoine Pitrou59fdd672010-10-08 10:37:08 +00002357- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2365
Éric Araujoef777bd2010-10-05 00:04:20 +00002366- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002367 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002368 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002369 replacement for old handle_accept() and avoids the user to call accept()
2370 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002394 retry the select() loop instead of bailing out. This is because select() can
2395 incorrectly report a socket as ready for reading (for example, if it received

2441
Antoine Pitrou98b46702010-09-18 22:59:00 +00002442- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002443 non-blocking mode: they return None when an operation would block (instead of
2444 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002445
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002446- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

2454 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002455
Georg Brandl27a28582010-10-10 09:49:21 +00002456- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2457 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002476- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002477 it possible for the user to create self-referencing ordered dictionaries which
2478 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002479 approach of using weakref proxies so that reference cycles never get created
2480 in the first place.
2481
Victor Stinnercb043522010-09-10 23:49:04 +00002482- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2483 encode the value with filesystem encoding and surrogateescape (instead of

Victor Stinnercb043522010-09-10 23:49:04 +00002485
Georg Brandl27a28582010-10-10 09:49:21 +00002486- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2487 environment variable to set the filesystem encoding at Python startup.
2488 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2489 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002490
Georg Brandl27a28582010-10-10 09:49:21 +00002491- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00002498- Logging: Added QueueHandler class to facilitate logging usage with
2499 multiprocessing.
2500
Georg Brandl27a28582010-10-10 09:49:21 +00002501- Issue #9707: Rewritten reference implementation of threading.local which is
2502 friendlier towards reference cycles. This change is not normally visible
2503 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002504
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002505- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2506 still return the id of the parent process after it has exited. This process
2507 id may even have been reused by another unrelated process.
2508
Georg Brandl27a28582010-10-10 09:49:21 +00002509- Issue #9792: In case of connection failure, socket.create_connection() would
2510 swallow the exception and raise a new one, making it impossible to fetch the
2511 original errno, or to filter timeout errors. Now the original error is
2512 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002513
Georg Brandl27a28582010-10-10 09:49:21 +00002514- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2515 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2516 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002517
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002518- Updates to the random module:
2519
Georg Brandl27a28582010-10-10 09:49:21 +00002520 * Document which parts of the module are guaranteed to stay the same across
2521 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002522
Georg Brandl27a28582010-10-10 09:49:21 +00002523 * Update the seed() method to use all of the bits in a string instead of just
2524 the hash value. This makes better use of the seed value and assures the
2525 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002526
Georg Brandl27a28582010-10-10 09:49:21 +00002527 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2528 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2529 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002530
2531 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002536- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2537 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2538 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002539

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002546- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002547 unsupported operation is attempted (for example, writing to a file open only
2548 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002549
Gregory P. Smith13b55292010-09-06 08:30:23 +00002550- hashlib has two new constant attributes: algorithms_guaranteed and
2551 algorithms_avaiable that respectively list the names of hash algorithms
2552 guaranteed to exist in all Python implementations and the names of hash
2553 algorithms available in the current process.
2554
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002555- A new package ``concurrent.futures`` as defined by PEP 3148.

2570 wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
2571 and the interpreter under test.

Ezio Melotti57221d02010-07-01 07:32:02 +00003065- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003066 start byte and the continuation byte(s) are now considered invalid, instead of
3067 the number of bytes specified by the start byte. E.g.:
3068 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3069 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3070 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3071 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003101- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003102 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

3115 TypeError instead of giving a DeprecationWarning when a float is parsed using
3116 the 'L' code (for long long). (All other integer codes already raise
3117 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003118
Victor Stinner600d3be2010-06-10 12:00:55 +00003119- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3121 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3122
Georg Brandl62069d32010-07-31 08:56:11 +00003123- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003125

Georg Brandl62069d32010-07-31 08:56:11 +00003127 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003450- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

3452 `va_copy`, but available on all python platforms.
3453
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003454- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3455 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3456 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003466- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003467 function declaration, which was kept for backwards compatibility reasons, is
3468 now removed (the macro was introduced in 1997!).

3478 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3479 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003480 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003507- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3508 allocator will be automatically disabled when running under Valgrind. This
3509 gives improved memory leak detection when running under Valgrind, while taking
3510 advantage of pymalloc at other times.

3603 on the original python prototype for the datetime module by Tim Peters with
3604 minor modifications by the PyPy project. The test suite now tests `datetime`
3605 module with and without `_datetime` acceleration using the same test cases.

Benjamin Peterson225168e2010-05-06 22:29:53 +00003819- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
3820 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
3821 file system encoding with the surrogateescape error handler (instead of
3822 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

3833
Victor Stinnerd17f2192010-08-15 09:56:07 +00003834- Issue #8390: tarfile uses surrogateescape as the default error handler

Georg Brandl62069d32010-07-31 08:56:11 +00003842- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3843 operation raises multiple signals and more than one of those signals is
3844 trapped, the specification determines the order in which the signals should be
3845 handled. In many cases this order wasn't being followed, leading to the wrong
3846 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00003885- Issue #8524: When creating an SSL socket, the timeout value of the original
3886 socket wasn't retained (instead, a socket with a positive timeout would be
3887 turned into a non-blocking SSL socket).

Georg Brandl62069d32010-07-31 08:56:11 +00004002- Issue #2531: Comparison operations between floats and Decimal instances now
4003 return a result based on the numeric values of the operands; previously they
4004 returned an arbitrary result based on the relative ordering of id(float) and
4005 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction

4021 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4022 <=> complex, and complex <=> complex comparisons.

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00004280- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4281 ownership when the group is not forced, because the group may be different

Georg Brandl62069d32010-07-31 08:56:11 +00004327- Issue #6816: runpy now provides a run_path function that allows Python code to
4328 execute file paths that refer to source or compiled Python files as well as
4329 zipfiles, directories and other valid sys.path entries that contain a
4330 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00004331 support the same flexibility as the CPython command line itself.
4332

4334 connection with another process, rather than looping endlessly. The default

4340
Michael Foord34c94622010-02-10 15:51:42 +00004341- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
4342 argument added to the TextTestRunner constructor allowing a different result
4343 class to be used without having to subclass.
Victor Stinnere125f132010-05-15 21:04:43 +00004344
Georg Brandl5f90d792010-08-01 22:31:05 +00004345- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
Michael Foord34c94622010-02-10 15:51:42 +00004346 name in failure reports even if the test has a docstring.
4347
Antoine Pitrou434736a2009-11-10 18:46:01 +00004348- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004349 default when instantiating a `threading.RLock` object. This makes recursive
4350 locks as fast as regular non-recursive locks (previously, they were slower by
4351 10x to 15x).
Antoine Pitrou434736a2009-11-10 18:46:01 +00004352

4354 those started through `threading.Thread` (for example, using
Antoine Pitroub0872682009-11-09 16:08:16 +00004355 `_thread.start_new_thread()`).
4356
Brett Cannone52c9192009-11-07 23:55:05 +00004357- Issue #7187: Importlib would not silence the IOError raised when trying to

4367 modification is done through it. This fixes inconsistencies and test failures
4368 on systems with slightly bogus mtime behaviour.

Georg Brandl62069d32010-07-31 08:56:11 +00004370- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
4371 from stdin so that existing input does not confuse it and lead to incorrect
4372 entry or an IOError. It also properly flushes it afterwards to avoid the
4373 terminal echoing the input afterwards on OSes such as Solaris.
Gregory P. Smith50467882009-11-01 18:42:17 +00004374

4377 large arguments (those with coefficient longer than the current precision) in
4378 shift and rotate.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004565- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004566 compared to other unix systems. In particular, os.getgroups() does not reflect
4567 any changes made using os.setgroups() but basicly always returns the same
4568 information as the id command. os.getgroups() can now return more than 16
4569 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004594- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4595 Prior to this change, timezone adjustment in utctimetuple() could produce
4596 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4600 directive. When the ``%z`` directive is present in the format string, an
4601 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4602 ``datetime.timezone`` instance constructed from the parsed offset. If both
4603 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4604 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004606- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004607 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4608 ``datetime.timezone``, return fixed name and UTC offset from their
4609 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4610 returns ``None``. A class attribute, ``utc`` contains an instance
4611 representing the UTC timezone. Original patch by Rafe Kaplan.

4628 with an improved 'binary-split' algorithm that uses fewer multiplications and
4629 allows many of the multiplications to be performed using plain C integer
4630 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

4635
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004636- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4637 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004638 the result is now always correctly rounded, and is equivalent to ``td /
4639 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004647- Issue #8300: When passing a non-integer argument to struct.pack with any
4648 integer format code, struct.pack first attempts to convert the non-integer
4649 using its __index__ method. If that method is non-existent or raises
4650 TypeError it goes on to try the __int__ method, as described below.

Antoine Pitrou716c4442009-05-23 19:04:03 +00005139- Issue #5761: Add the name of the underlying file to the repr() of various

Mark Dickinson865e01a2009-05-07 16:37:01 +00005217- Issue #5914: Add new C API function PyOS_string_to_double, and
5218 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5219
Eric Smith741191f2009-05-06 13:08:15 +00005220- Issue #3382: float.__format__, complex.__format__, and %-formatting
5221 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

Mark Hammond5a607a32009-05-06 08:04:54 +00005224- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5225 in all operations, including splitdrive, split, etc. splitunc() now issues

5227
Eric Smith63376222009-05-05 14:04:18 +00005228- Issue #5920: For float.__format__, change the behavior with the
5229 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5230 to be like 'g' but with at least one decimal point and with a
5231 default precision of 12. Previously, the behavior the same but with
5232 a default precision of 6. This more closely matches str(), and
5233 reduces surprises when adding alignment flags to the empty
5234 presentation type. This also affects the new complex.__format__ in
5235 the same way.
5236
Martin v. Löwis011e8422009-05-05 04:43:17 +00005237- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005248- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5249 received a new method, detach(). detach() disconnects the underlying stream
5250 from the buffer or text IO and returns it.
5251
Mark Dickinson33841c32009-05-01 15:37:04 +00005252- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5253 floats with absolute value over 1e50. Also remove length
5254 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

5261 never gives more than the requested number of significant digits.
5262
Eric Smith6dc46f52009-04-27 20:39:49 +00005263- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5274 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005278- Issue #1869 (and many duplicates): make round(x, n) correctly
5279 rounded for a float x, by using the decimal <-> binary conversions
5280 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5281 consistently agrees with format(x, '.2f').
5282
Benjamin Petersonae937c02009-04-18 20:54:08 +00005283- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5284 some builtin types.

Eric Smith0923d1d2009-04-16 20:16:10 +00005286- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5287
Eric Smith35e84722009-04-16 20:21:28 +00005288- Issue #5515: str.format() type 'n' combined with commas and leading
5289 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005290
5291- Implement PEP 378, Format Specifier for Thousands Separator, for
5292 floats.
5293
Mark Dickinson3370cce2009-04-17 22:40:53 +00005294- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005295 1e11, not 1e12. This avoids printing 13 significant digits in
5296 situations where only 12 of them are correct. Example problem
5297 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5298 long time.)
5299
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005300- Issue #1580: On most platforms, use a 'short' float repr: for a
5301 finite float x, repr(x) now outputs a string based on the shortest
5302 sequence of decimal digits that rounds to x. Previous behaviour was
5303 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005304 Another minor difference is that the new repr switches to
5305 exponential notation at 1e16 instead of the previous 1e17; this
5306 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005307
5308 There's a new sys attribute sys.float_repr_style, which takes
5309 the value 'short' to indicate that we're using short float repr,
5310 and 'legacy' if the short float repr isn't available for one
5311 reason or another.
5312
5313 The float repr change involves incorporating David Gay's 'perfect
5314 rounding' code into the Python core (it's in Python/dtoa.c). As a
5315 secondary consequence, all string-to-float and float-to-string
5316 conversions (including all float formatting operations) will be
5317 correctly rounded on these platforms.
5318
Georg Brandl5f90d792010-08-01 22:31:05 +00005319 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005320 this change does not apply.
5321
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005322- Issue #5759: float() didn't call __float__ on str subclasses.
5323
Georg Brandlabc38772009-04-12 15:51:51 +00005324- The string.maketrans() function is deprecated; there is a new static method
5325 maketrans() on the bytes and bytearray classes. This removes confusion about
5326 the types string.maketrans() is supposed to work with, and mirrors the
5327 methods available on the str class.
5328
R. David Murraydc6da8a2009-04-09 22:16:43 +00005329- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5330 its clarity and its speed.
5331
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005332- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``

Walter Dörwald8dc33d52009-05-06 14:41:26 +00005335- Issue #3739: The unicode-internal encoder now reports the number of characters

5496 untrackable objects are not tracked by the garbage collector. This can
5497 reduce the size of collections and therefore the garbage collection overhead
5498 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00005590- Issue #5463: In struct module, remove deprecated overflow wrapping
5591 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005592 struct.error instead of returning b'\xff\xff\xff\xff'. The
5593 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5594 have been removed from the struct module.

5610 used when using str.format() with str, int, and float arguments.
5611
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005612- Issue #5249: time.strftime returned malformed string when format string
5613 contained non ascii character on windows.
5614
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005615- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

5617
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005618- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5619 rotating the object pointer by 4 bits to the right.
5620
Mark Dickinson87ec0852009-02-09 17:15:59 +00005621- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5622 it now forces its argument to double before testing for infinity.
5623
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005624- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5625 returns a non-number type.
5626
Benjamin Peterson87618552009-02-08 15:00:52 +00005627- Issue #5182: Removed memoryview.__str__.

5632 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005633
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005634- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005635 were suppressing all exceptions. These include list() and bytearray().
5636
Mark Dickinson1124e712009-01-28 21:25:58 +00005637- Issue #4707: round(x, n) now returns an integer if x is an integer.
5638 Previously it returned a float.
5639
Antoine Pitroub52ec782009-01-25 16:34:23 +00005640- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5641 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5642 evaluation loop is compiled with a new dispatch mechanism which gives
5643 speedups of up to 20%, depending on the system, on various benchmarks.
5644
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005645- Issue #4874: Most builtin decoders now reject unicode input.

5651
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005652- Issue #4838: When a module is deallocated, free the memory backing the
5653 optional module state data.
5654
Mark Dickinson8055afd2009-01-17 10:04:45 +00005655- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005656 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005657
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005658- Issue #4935: The overflow checking code in the expandtabs() method common
5659 to str, bytes and bytearray could be optimized away by the compiler, letting
5660 the interpreter segfault instead of raising an error.
5661
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005662- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5663 __next__ method.
5664
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005665- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5666 function no longer attempt to call the __long__ slot to convert an object
5667 to an integer. Only the __int__ and __trunc__ slots are examined.
5668
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005669- Issue #4893: Use NT threading on CE.
5670

5672
Antoine Pitrouab868312009-01-10 15:40:25 +00005673- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5674 common cases are optimized thanks to a dedicated fast path and a moderate
5675 amount of loop unrolling.
5676
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005677- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5678 collecting the oldest generation) so that allocating lots of objects without
5679 destroying them does not show quadratic performance. Based on a proposal by
5680 Martin von Löwis at
5681 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5682
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005683- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005684 having been closed (for instance, a read() call could return some
5685 previously buffered data). Patch by Dmitry Vasiliev.
5686
Antoine Pitrou05608432009-01-09 18:53:14 +00005687- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5688 flag to work properly. Furthermore, when specifying -u, the text stdout
5689 and stderr streams have line-by-line buffering enabled (the default being
5690 to buffer arbitrary chunks of data).
5691
Raymond Hettinger35631532009-01-09 03:58:09 +00005692- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5693 instead of ints (reducing its size from 4 to 8 times thereby reducing
5694 Python's overall memory).
5695
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005696- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5697 an existing .py counterpart, override the co_filename attributes of all
5698 code objects if the original filename is obsolete (which can happen if the
5699 file has been renamed, moved, or if it is accessed through different paths).
5700 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5701
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005702- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5703 one byte. Also fixes the meaning of len() so that it returns the number of
5704 items, rather than the size in bytes.
5705
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005706- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5707
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005708- Issue #4747: When the terminal does not use utf-8, executing a script with
5709 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5710
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005711- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5712 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005713
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005714- Issue #3680: Reference cycles created through a dict, set or deque iterator
5715 did not get collected.
5716
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005717- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5718 where the tp_hash and tp_dict slots are both NULL.
5719
Georg Brandlccc47b62008-12-28 11:44:14 +00005720- Issue #4759: None is now allowed as the first argument of
5721 bytearray.translate(). It was always allowed for bytes.translate().
5722
Skip Montanaro80072cb2008-12-23 03:51:14 +00005723- Added test case to ensure attempts to read from a file opened for writing
5724 fail.
5725
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005726- Issue #3106: Speedup some comparisons (str/str and int/int).

5730
Antoine Pitrou621601a2008-12-17 23:18:19 +00005731- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5732 print elapsed times, not only when some objects are uncollectable /
5733 unreachable. Original patch by Neil Schemenauer.
5734
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005735- Issue #3439: Add a bit_length method to int.
5736
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005737- Issue #2173: When getting device encoding, check that return value of
5738 nl_langinfo is not the empty string. This was causing silent build
5739 failures on OS X.
5740
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005741- Issue #4597: Fixed several opcodes that weren't always propagating
5742 exceptions.
5743
5744- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005745 context manager returns a value that cannot be converted to a bool.
5746
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005747- Issue #4445: Replace "sizeof(PyBytesObject)" with
5748 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5749 bytes instances. On a typical machine this saves 3 bytes of memory
5750 (on average) per allocation of a bytes instance.
5751
Christian Heimesa872de52008-12-05 08:26:55 +00005752- Issue #4533: File read operation was dreadfully slow due to a slowly
5753 growing read buffer. Fixed by using the same growth rate algorithm as
5754 Python 2.x.
5755
Antoine Pitrou5504e892008-12-06 21:27:53 +00005756- Issue #4509: Various issues surrounding resize of bytearray objects to
5757 which there are buffer exports (e.g. memoryview instances).
5758
Georg Brandlf9734072008-12-07 15:30:06 +00005759- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5760 method on file objects with closefd=False. The file descriptor is still
5761 kept open but the file object behaves like a closed file. The ``FileIO``
5762 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005763
Antoine Pitroubc420402008-12-07 20:14:49 +00005764- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5765 larger than 1.
5766

5770
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005771- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5772 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5773 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5774 of using the replace error handler in PyUnicode_DecodeUTF8().
