R. David Murray5b2d9dd2011-01-09 02:35:24 +00001245- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001246 continuation line in the formatted value has no leading white space and looks
1247 like a header. Since Generator uses Header to format all headers, this check
1248 is made for all headers in any serialized message at serialization time. This
1249 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001250
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001251- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +00001257- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001258 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001259 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001260
Éric Araujof0ab5d62011-05-29 03:43:59 +02001261- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001262 rfc2047-encoding header values with embedded newlines, leaving them without
1263 folding whitespace. It now uses the continuation_ws, as it does for
1264 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001265
Victor Stinner3ec899f2011-01-08 16:37:47 +00001266- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1267 time.asctime(), time.ctime() and time.strftime() functions will now format
1268 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1269 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1270 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1271 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001272
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001273- Issue #7858: Raise an error properly when os.utime() fails under Windows

Victor Stinner4bd81722011-01-06 00:49:38 +00001279- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1280 compilation (if the input is a string).
1281
Antoine Pitrou600232b2011-01-05 21:03:42 +00001282- Issue #7995: When calling accept() on a socket with a timeout, the returned

Georg Brandl255abdd2011-01-16 14:17:26 +00001329 method. According to RFC 3986, these characters can be a part of params in

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002248- Issue #10068: Global objects which have reference cycles with their module's
2249 dict are now cleared again. This causes issue #7140 to appear again.
2250
Victor Stinner257d38f2010-10-09 10:12:11 +00002251- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002252 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002253
Georg Brandl27a28582010-10-10 09:49:21 +00002254- ast.literal_eval() can now handle negative numbers. It is also a little more
2255 liberal in what it accepts without compromising the safety of the evaluation.
2256 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002257
Benjamin Peterson970d1882010-10-02 17:55:47 +00002258- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2259 result metaclasses can now be ABCs (see #9533).
2260
Victor Stinneraef57e32010-10-02 11:50:49 +00002261- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2262
Victor Stinner5593d8a2010-10-02 11:11:27 +00002263- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002264 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2265 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002266
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002267- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002268 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002269
Victor Stinner137c34c2010-09-29 10:25:54 +00002270- Issue #9979: Create function PyUnicode_AsWideCharString().
2271
Brett Cannon5305a992010-09-27 21:08:38 +00002272- Issue #7397: Mention that importlib.import_module() is probably what someone
2273 really wants to be using in __import__'s docstring.
2274
Georg Brandl27a28582010-10-10 09:49:21 +00002275- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2276 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002277
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002278- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002279 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002280
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002281- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2282
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002283- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2284 threads are still running. Instead, reinitialize the GIL on a second call to
2285 Py_Initialize().
2286
Georg Brandl27a28582010-10-10 09:49:21 +00002287- All SyntaxErrors now have a column offset and therefore a caret when the error
2288 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002289
Brett Cannonbc2eff32010-09-19 21:39:02 +00002290- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2291 module that was imported, but instead gets the module from sys.modules.
2292
Nick Coghlan37ee8502010-12-03 14:26:13 +00002293- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002294 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002295
Georg Brandl27a28582010-10-10 09:49:21 +00002296- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2297 with a non-empty format string. This is an effort to future-proof user
2298 code. If a derived class does not currently implement __format__ but later
2299 adds its own __format__, it would most likely break user code that had
2300 supplied a format string. This will be changed to a DeprecationWaring in
2301 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002302
Antoine Pitrou1df15362010-09-13 14:16:46 +00002303- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2304 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2305 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2306
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002307- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2308 functions from the libc caused the methods .upper() and lower() to become
2309 locale aware and created subtly wrong results.
2310
Georg Brandl27a28582010-10-10 09:49:21 +00002311- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2312 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002313
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002314- Issue #4617: Previously it was illegal to delete a name from the local
2315 namespace if it occurs as a free variable in a nested block. This limitation
2316 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2317
Georg Brandl27a28582010-10-10 09:49:21 +00002318- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2319 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2320 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2321 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002322
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002323- Issue #9757: memoryview objects get a release() method to release the
2324 underlying buffer (previously this was only done when deallocating the
2325 memoryview), and gain support for the context management protocol.
2326
Antoine Pitrou079ce542010-09-08 12:37:10 +00002327- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2328 thread-local storage key.

2338
2339- Issue #1718574: Fix options that were supposed to accept arguments but did
2340 not in build_clib.
2341
Antoine Pitroudbec7802010-10-10 09:37:12 +00002342- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2343
R. David Murray96fd54e2010-10-08 15:55:28 +00002344- Issue #4661: email can now parse bytes input and generate either converted
2345 7bit output or bytes output. Email version bumped to 5.1.0.
2346
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002347- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2348 verification for higher-level protocols.
2349
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002350- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2351 after the file is closed. Patch by Jeffrey Finkelstein.
2352
Éric Araujo6108bf52010-10-04 23:52:37 +00002353- Issue #9042: Fix interaction of custom translation classes and caching in
2354 gettext.
2355
Éric Araujoef777bd2010-10-05 00:04:20 +00002356- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002357 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002358 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002359 replacement for old handle_accept() and avoids the user to call accept()
2360 directly.
2361
Lars Gustäbel331b8002010-10-04 15:18:47 +00002362- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2363 gname field.
2364
Georg Brandl27a28582010-10-10 09:49:21 +00002365- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2366 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002367
R. David Murray5397e862010-10-02 15:58:26 +00002368- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2369 characters that appear inside quoted strings in email addresses.
2370
Georg Brandl27a28582010-10-10 09:49:21 +00002371- Issue #10004: quoprimime no longer generates a traceback when confronted with
2372 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002373
Georg Brandl27a28582010-10-10 09:49:21 +00002374- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2375 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002376
Georg Brandl27a28582010-10-10 09:49:21 +00002377- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2378 conforms to the philosophy of bytes and unicode separation in Python 3. A
2379 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002381- Issue #9962: GzipFile now has the peek() method.
2382
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002383- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002384 retry the select() loop instead of bailing out. This is because select() can
2385 incorrectly report a socket as ready for reading (for example, if it received
2386 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002387
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002388- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002390- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002391 received. Now sendall() properly calls signal handlers if necessary, and
2392 retries sending if these returned successfully, including on sockets with a
2393 timeout.

2431
Antoine Pitrou98b46702010-09-18 22:59:00 +00002432- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002433 non-blocking mode: they return None when an operation would block (instead of
2434 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002435
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002436- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00002446- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2447 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002466- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002467 it possible for the user to create self-referencing ordered dictionaries which
2468 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002469 approach of using weakref proxies so that reference cycles never get created
2470 in the first place.
2471
Victor Stinnercb043522010-09-10 23:49:04 +00002472- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2473 encode the value with filesystem encoding and surrogateescape (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002476- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2477 environment variable to set the filesystem encoding at Python startup.
2478 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2479 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002480
Georg Brandl27a28582010-10-10 09:49:21 +00002481- Issue #9410: Various optimizations to the pickle module, leading to speedups

2490
Georg Brandl27a28582010-10-10 09:49:21 +00002491- Issue #9707: Rewritten reference implementation of threading.local which is
2492 friendlier towards reference cycles. This change is not normally visible
2493 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002494
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002495- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2496 still return the id of the parent process after it has exited. This process
2497 id may even have been reused by another unrelated process.
2498
Georg Brandl27a28582010-10-10 09:49:21 +00002499- Issue #9792: In case of connection failure, socket.create_connection() would
2500 swallow the exception and raise a new one, making it impossible to fetch the
2501 original errno, or to filter timeout errors. Now the original error is
2502 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002504- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2505 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2506 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002507
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002508- Updates to the random module:
2509
Georg Brandl27a28582010-10-10 09:49:21 +00002510 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002513 * Update the seed() method to use all of the bits in a string instead of just
2514 the hash value. This makes better use of the seed value and assures the
2515 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002517 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2518 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2519 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002520
2521 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002540- hashlib has two new constant attributes: algorithms_guaranteed and
2541 algorithms_avaiable that respectively list the names of hash algorithms
2542 guaranteed to exist in all Python implementations and the names of hash
2543 algorithms available in the current process.
2544

Ezio Melotti57221d02010-07-01 07:32:02 +00003055- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003056 start byte and the continuation byte(s) are now considered invalid, instead of
3057 the number of bytes specified by the start byte. E.g.:
3058 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3059 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3060 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3061 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003091- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003092 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

3105 TypeError instead of giving a DeprecationWarning when a float is parsed using
3106 the 'L' code (for long long). (All other integer codes already raise
3107 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00003117 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

3134 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003135 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3136 (2) The comparison raised an OverflowError for large integers, leading to
3137 unpredictable exceptions when combining integers and complex objects in sets
3138 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003440- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

3442 `va_copy`, but available on all python platforms.
3443
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003444- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3445 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3446 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003456- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003457 function declaration, which was kept for backwards compatibility reasons, is
3458 now removed (the macro was introduced in 1997!).

3468 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3469 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003470 to match the behaviour of the other integer format codes.

3481 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3482 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3499 gives improved memory leak detection when running under Valgrind, while taking
3500 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003577 applications that use a lot of regular expressions and limits the impact of
3578 the performance hit anytime the cache is exceeded.

3591 module is renamed to `_datetime` and if available, overrides all classes
3592 defined in datetime with fast C impementation. Python implementation is based
3593 on the original python prototype for the datetime module by Tim Peters with
3594 minor modifications by the PyPy project. The test suite now tests `datetime`
3595 module with and without `_datetime` acceleration using the same test cases.

3810 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
3811 file system encoding with the surrogateescape error handler (instead of
3812 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

3815
Georg Brandl62069d32010-07-31 08:56:11 +00003816- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
3817 messages when accessing undefined class attributes because of the cheap
3818 inheritance with the underlying socket object. The cheap inheritance has been
3819 deprecated.

3823
Victor Stinnerd17f2192010-08-15 09:56:07 +00003824- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003825 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00003832- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3833 operation raises multiple signals and more than one of those signals is
3834 trapped, the specification determines the order in which the signals should be
3835 handled. In many cases this order wasn't being followed, leading to the wrong
3836 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00003870- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3871 the method could block indefinitely if called just before the event loop
3872 started running. This also fixes the occasional freezes witnessed in
3873 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00003875- Issue #8524: When creating an SSL socket, the timeout value of the original
3876 socket wasn't retained (instead, a socket with a positive timeout would be
3877 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003878
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003879- Issue #5103: SSL handshake would ignore the socket timeout and block
3880 indefinitely if the other end didn't respond.
3881
Georg Brandl62069d32010-07-31 08:56:11 +00003882- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00003894- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3895 string "python" as the *ident*. openlog() arguments are all optional and
3896 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003897
Georg Brandl62069d32010-07-31 08:56:11 +00003898- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3899 non-infinite timeout. Also make that method friendlier with applications

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003951 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003952 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00003987- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3988 InvalidOperation instead of returning False. (Comparisons involving a quiet
3989 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3990 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003992- Issue #2531: Comparison operations between floats and Decimal instances now
3993 return a result based on the numeric values of the operands; previously they
3994 returned an arbitrary result based on the relative ordering of id(float) and
3995 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3996 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003997
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003998- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004000- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004001 argument `-` which tells it to read files to compile from stdin. Each line is

4010 Fractions instance now raise TypeError instead of returning True/False. This
4011 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4012 <=> complex, and complex <=> complex comparisons.

4598 ``datetime.timezone``, return fixed name and UTC offset from their
4599 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

5206
Mark Dickinson865e01a2009-05-07 16:37:01 +00005207- Issue #5914: Add new C API function PyOS_string_to_double, and
5208 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5209
Eric Smith741191f2009-05-06 13:08:15 +00005210- Issue #3382: float.__format__, complex.__format__, and %-formatting
5211 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5212 affects nan -> NAN and inf -> INF.
5213
Mark Hammond5a607a32009-05-06 08:04:54 +00005214- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5215 in all operations, including splitdrive, split, etc. splitunc() now issues
5216 a PendingDeprecation warning.
5217
Eric Smith63376222009-05-05 14:04:18 +00005218- Issue #5920: For float.__format__, change the behavior with the
5219 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5220 to be like 'g' but with at least one decimal point and with a
5221 default precision of 12. Previously, the behavior the same but with
5222 a default precision of 6. This more closely matches str(), and
5223 reduces surprises when adding alignment flags to the empty
5224 presentation type. This also affects the new complex.__format__ in
5225 the same way.
5226
Martin v. Löwis011e8422009-05-05 04:43:17 +00005227- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5228
R. David Murrayb18500d2009-05-04 22:59:07 +00005229- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5230 shadowed by classtype's, even if it was None. property now
5231 inserts the __doc__ into the subclass instance __dict__.
5232
Antoine Pitrou244651a2009-05-04 18:56:13 +00005233- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

5235
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005236- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005237
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005238- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5239 received a new method, detach(). detach() disconnects the underlying stream
5240 from the buffer or text IO and returns it.
5241
Mark Dickinson33841c32009-05-01 15:37:04 +00005242- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5243 floats with absolute value over 1e50. Also remove length
5244 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5245 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005246
Eric Smith741191f2009-05-06 13:08:15 +00005247- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005248 format(complex(1, 2./3), '.5') now produces a sensible result.
5249
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005250- Issue #5864: Fix empty format code formatting for floats so that it
5251 never gives more than the requested number of significant digits.
5252
Eric Smith6dc46f52009-04-27 20:39:49 +00005253- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5259 titlecase, but not their own uppercase.
5260

5262
Mark Dickinsonad476da2009-04-23 19:14:16 +00005263- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5264 z involves nans, infs or negative zeros.
5265
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005266- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005267
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005268- Issue #1869 (and many duplicates): make round(x, n) correctly
5269 rounded for a float x, by using the decimal <-> binary conversions
5270 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5271 consistently agrees with format(x, '.2f').
5272
Benjamin Petersonae937c02009-04-18 20:54:08 +00005273- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5277
Eric Smith35e84722009-04-16 20:21:28 +00005278- Issue #5515: str.format() type 'n' combined with commas and leading
5279 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005280
5281- Implement PEP 378, Format Specifier for Thousands Separator, for
5282 floats.
5283
Mark Dickinson3370cce2009-04-17 22:40:53 +00005284- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005285 1e11, not 1e12. This avoids printing 13 significant digits in
5286 situations where only 12 of them are correct. Example problem
5287 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5288 long time.)
5289
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005290- Issue #1580: On most platforms, use a 'short' float repr: for a
5291 finite float x, repr(x) now outputs a string based on the shortest
5292 sequence of decimal digits that rounds to x. Previous behaviour was
5293 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005294 Another minor difference is that the new repr switches to
5295 exponential notation at 1e16 instead of the previous 1e17; this
5296 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005297
5298 There's a new sys attribute sys.float_repr_style, which takes
5299 the value 'short' to indicate that we're using short float repr,
5300 and 'legacy' if the short float repr isn't available for one
5301 reason or another.
5302
5303 The float repr change involves incorporating David Gay's 'perfect
5304 rounding' code into the Python core (it's in Python/dtoa.c). As a
5305 secondary consequence, all string-to-float and float-to-string
5306 conversions (including all float formatting operations) will be
5307 correctly rounded on these platforms.
5308
Georg Brandl5f90d792010-08-01 22:31:05 +00005309 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005310 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005312- Issue #5759: float() didn't call __float__ on str subclasses.
5313
Georg Brandlabc38772009-04-12 15:51:51 +00005314- The string.maketrans() function is deprecated; there is a new static method
5315 maketrans() on the bytes and bytearray classes. This removes confusion about
5316 the types string.maketrans() is supposed to work with, and mirrors the
5317 methods available on the str class.
5318
R. David Murraydc6da8a2009-04-09 22:16:43 +00005319- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005582 struct.error instead of returning b'\xff\xff\xff\xff'. The
5583 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5584 have been removed from the struct module.

5610
Mark Dickinson87ec0852009-02-09 17:15:59 +00005611- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5612 it now forces its argument to double before testing for infinity.
5613
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005614- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005623
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005624- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005625 were suppressing all exceptions. These include list() and bytearray().

5629
Antoine Pitroub52ec782009-01-25 16:34:23 +00005630- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5631 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5632 evaluation loop is compiled with a new dispatch mechanism which gives
5633 speedups of up to 20%, depending on the system, on various benchmarks.
5634
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005635- Issue #4874: Most builtin decoders now reject unicode input.

5643 optional module state data.
5644
Mark Dickinson8055afd2009-01-17 10:04:45 +00005645- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005646 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005647
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005648- Issue #4935: The overflow checking code in the expandtabs() method common
5649 to str, bytes and bytearray could be optimized away by the compiler, letting
5650 the interpreter segfault instead of raising an error.
5651
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005652- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5653 __next__ method.
5654
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005655- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5656 function no longer attempt to call the __long__ slot to convert an object
5657 to an integer. Only the __int__ and __trunc__ slots are examined.
5658
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005659- Issue #4893: Use NT threading on CE.
5660

5662
Antoine Pitrouab868312009-01-10 15:40:25 +00005663- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5664 common cases are optimized thanks to a dedicated fast path and a moderate
5665 amount of loop unrolling.
5666
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005667- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5668 collecting the oldest generation) so that allocating lots of objects without
5669 destroying them does not show quadratic performance. Based on a proposal by
5670 Martin von Löwis at
5671 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5672
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005673- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005674 having been closed (for instance, a read() call could return some
5675 previously buffered data). Patch by Dmitry Vasiliev.
5676
Antoine Pitrou05608432009-01-09 18:53:14 +00005677- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5678 flag to work properly. Furthermore, when specifying -u, the text stdout
5679 and stderr streams have line-by-line buffering enabled (the default being
5680 to buffer arbitrary chunks of data).
5681
Raymond Hettinger35631532009-01-09 03:58:09 +00005682- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5683 instead of ints (reducing its size from 4 to 8 times thereby reducing
5684 Python's overall memory).
5685
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005686- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5687 an existing .py counterpart, override the co_filename attributes of all
5688 code objects if the original filename is obsolete (which can happen if the
5689 file has been renamed, moved, or if it is accessed through different paths).
5690 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5691
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005692- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5693 one byte. Also fixes the meaning of len() so that it returns the number of
5694 items, rather than the size in bytes.
5695
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005696- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5697
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005698- Issue #4747: When the terminal does not use utf-8, executing a script with
5699 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5700
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005701- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5702 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005703
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005704- Issue #3680: Reference cycles created through a dict, set or deque iterator
5705 did not get collected.
5706
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005707- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5708 where the tp_hash and tp_dict slots are both NULL.
5709
Georg Brandlccc47b62008-12-28 11:44:14 +00005710- Issue #4759: None is now allowed as the first argument of
5711 bytearray.translate(). It was always allowed for bytes.translate().
5712
Skip Montanaro80072cb2008-12-23 03:51:14 +00005713- Added test case to ensure attempts to read from a file opened for writing
5714 fail.
5715
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005716- Issue #3106: Speedup some comparisons (str/str and int/int).

5720
Antoine Pitrou621601a2008-12-17 23:18:19 +00005721- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5724
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005725- Issue #3439: Add a bit_length method to int.
5726
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005727- Issue #2173: When getting device encoding, check that return value of
5728 nl_langinfo is not the empty string. This was causing silent build
5729 failures on OS X.
5730
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005731- Issue #4597: Fixed several opcodes that weren't always propagating
5732 exceptions.
5733
5734- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005735 context manager returns a value that cannot be converted to a bool.
5736
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005737- Issue #4445: Replace "sizeof(PyBytesObject)" with
5738 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5739 bytes instances. On a typical machine this saves 3 bytes of memory
5740 (on average) per allocation of a bytes instance.
5741
Christian Heimesa872de52008-12-05 08:26:55 +00005742- Issue #4533: File read operation was dreadfully slow due to a slowly
5743 growing read buffer. Fixed by using the same growth rate algorithm as
5744 Python 2.x.
5745
Antoine Pitrou5504e892008-12-06 21:27:53 +00005746- Issue #4509: Various issues surrounding resize of bytearray objects to
5747 which there are buffer exports (e.g. memoryview instances).
5748
Georg Brandlf9734072008-12-07 15:30:06 +00005749- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5750 method on file objects with closefd=False. The file descriptor is still
5751 kept open but the file object behaves like a closed file. The ``FileIO``
5752 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005753
Antoine Pitroubc420402008-12-07 20:14:49 +00005754- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5755 larger than 1.

5760
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005761- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5762 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5763 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5764 of using the replace error handler in PyUnicode_DecodeUTF8().
