Victor Stinner89e34362011-01-07 18:47:22 +00001180
Martin v. Löwisc83bc3c2011-01-06 19:15:47 +00001181- Remove buffer API from stable ABI for now, see #10181.

Georg Brandl255abdd2011-01-16 14:17:26 +00001208- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
1209 and a non-zero offset, and an attempt to read past the end of file is made
1210 (IndexError is raised instead). Patch by Ross Lagerwall.
Antoine Pitrou85f46152011-01-15 16:17:07 +00001211

Ned Deily4ce92b22011-01-15 04:37:12 +00001222
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001223- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
1224 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +00001225 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn

1239 twice.
Georg Brandl619e7ba2011-01-09 07:38:51 +00001240
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001241- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001242 continuation line in the formatted value has no leading white space and looks
1243 like a header. Since Generator uses Header to format all headers, this check
1244 is made for all headers in any serialized message at serialization time. This
1245 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001246
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001247- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

1251 comparisons that could lead to infinite recursion.
1252
R. David Murray92532142011-01-07 23:25:30 +00001253- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001254 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001255 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001256
Éric Araujof0ab5d62011-05-29 03:43:59 +02001257- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001258 rfc2047-encoding header values with embedded newlines, leaving them without
1259 folding whitespace. It now uses the continuation_ws, as it does for
1260 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001261
Victor Stinner3ec899f2011-01-08 16:37:47 +00001262- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1263 time.asctime(), time.ctime() and time.strftime() functions will now format
1264 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1265 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1266 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1267 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001268
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001269- Issue #7858: Raise an error properly when os.utime() fails under Windows

1274
Victor Stinner4bd81722011-01-06 00:49:38 +00001275- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1276 compilation (if the input is a string).
1277
Antoine Pitrou600232b2011-01-05 21:03:42 +00001278- Issue #7995: When calling accept() on a socket with a timeout, the returned
Antoine Pitroudc51a3c2011-01-05 22:43:26 +00001279 socket is now always blocking, regardless of the operating system.

1291 the input buffer length doesn't fit into an unsigned int (length bigger than
1292 2^32-1 bytes).
1293
Georg Brandl255abdd2011-01-16 14:17:26 +00001294- Issue #6643: Reinitialize locks held within the threading module after fork to

Georg Brandl255abdd2011-01-16 14:17:26 +00001325 method. According to RFC 3986, these characters can be a part of params in

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001899 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2243
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002244- Issue #10068: Global objects which have reference cycles with their module's
2245 dict are now cleared again. This causes issue #7140 to appear again.
2246
Victor Stinner257d38f2010-10-09 10:12:11 +00002247- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002248 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002249
Georg Brandl27a28582010-10-10 09:49:21 +00002250- ast.literal_eval() can now handle negative numbers. It is also a little more
2251 liberal in what it accepts without compromising the safety of the evaluation.
2252 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002253
Benjamin Peterson970d1882010-10-02 17:55:47 +00002254- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2255 result metaclasses can now be ABCs (see #9533).
2256
Victor Stinneraef57e32010-10-02 11:50:49 +00002257- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2258
Victor Stinner5593d8a2010-10-02 11:11:27 +00002259- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002260 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2261 32 bits wchar_t (eg. Linux in narrow build).

2267
Brett Cannon5305a992010-09-27 21:08:38 +00002268- Issue #7397: Mention that importlib.import_module() is probably what someone
2269 really wants to be using in __import__'s docstring.
2270
Georg Brandl27a28582010-10-10 09:49:21 +00002271- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2272 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002273
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002274- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002275 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002277- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2278
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002279- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2280 threads are still running. Instead, reinitialize the GIL on a second call to
2281 Py_Initialize().
2282
Georg Brandl27a28582010-10-10 09:49:21 +00002283- All SyntaxErrors now have a column offset and therefore a caret when the error
2284 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002285
Brett Cannonbc2eff32010-09-19 21:39:02 +00002286- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2287 module that was imported, but instead gets the module from sys.modules.
2288
Nick Coghlan37ee8502010-12-03 14:26:13 +00002289- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002290 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002291
Georg Brandl27a28582010-10-10 09:49:21 +00002292- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2293 with a non-empty format string. This is an effort to future-proof user
2294 code. If a derived class does not currently implement __format__ but later
2295 adds its own __format__, it would most likely break user code that had
2296 supplied a format string. This will be changed to a DeprecationWaring in
2297 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002298
Antoine Pitrou1df15362010-09-13 14:16:46 +00002299- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2300 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2301 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2302
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002303- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2304 functions from the libc caused the methods .upper() and lower() to become
2305 locale aware and created subtly wrong results.
2306
Georg Brandl27a28582010-10-10 09:49:21 +00002307- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2308 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002309
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002310- Issue #4617: Previously it was illegal to delete a name from the local
2311 namespace if it occurs as a free variable in a nested block. This limitation
2312 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2313
Georg Brandl27a28582010-10-10 09:49:21 +00002314- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2315 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2316 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2317 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002318
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002319- Issue #9757: memoryview objects get a release() method to release the
2320 underlying buffer (previously this was only done when deallocating the
2321 memoryview), and gain support for the context management protocol.
2322
Antoine Pitrou079ce542010-09-08 12:37:10 +00002323- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2324 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002340- Issue #4661: email can now parse bytes input and generate either converted
2341 7bit output or bytes output. Email version bumped to 5.1.0.
2342
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002343- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2345
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002346- Issue #9759: GzipFile now raises ValueError when an operation is attempted

2348
Éric Araujo6108bf52010-10-04 23:52:37 +00002349- Issue #9042: Fix interaction of custom translation classes and caching in
2350 gettext.
2351
Éric Araujoef777bd2010-10-05 00:04:20 +00002352- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002353 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002354 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002355 replacement for old handle_accept() and avoids the user to call accept()
2356 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002358- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002379- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002380 retry the select() loop instead of bailing out. This is because select() can
2381 incorrectly report a socket as ready for reading (for example, if it received
2382 some data with an invalid checksum).

2427
Antoine Pitrou98b46702010-09-18 22:59:00 +00002428- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002429 non-blocking mode: they return None when an operation would block (instead of
2430 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002431
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002432- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002462- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002463 it possible for the user to create self-referencing ordered dictionaries which
2464 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002465 approach of using weakref proxies so that reference cycles never get created
2466 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002472- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2473 environment variable to set the filesystem encoding at Python startup.
2474 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2475 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002476
Georg Brandl27a28582010-10-10 09:49:21 +00002477- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00002484- Logging: Added QueueHandler class to facilitate logging usage with
2485 multiprocessing.
2486
Georg Brandl27a28582010-10-10 09:49:21 +00002487- Issue #9707: Rewritten reference implementation of threading.local which is
2488 friendlier towards reference cycles. This change is not normally visible
2489 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002490
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002491- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2492 still return the id of the parent process after it has exited. This process
2493 id may even have been reused by another unrelated process.
2494
Georg Brandl27a28582010-10-10 09:49:21 +00002495- Issue #9792: In case of connection failure, socket.create_connection() would
2496 swallow the exception and raise a new one, making it impossible to fetch the
2497 original errno, or to filter timeout errors. Now the original error is
2498 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002500- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2501 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2502 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002503
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002504- Updates to the random module:
2505
Georg Brandl27a28582010-10-10 09:49:21 +00002506 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002509 * Update the seed() method to use all of the bits in a string instead of just
2510 the hash value. This makes better use of the seed value and assures the
2511 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002513 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2514 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2515 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002516
2517 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002536- hashlib has two new constant attributes: algorithms_guaranteed and
2537 algorithms_avaiable that respectively list the names of hash algorithms
2538 guaranteed to exist in all Python implementations and the names of hash
2539 algorithms available in the current process.

Ezio Melotti57221d02010-07-01 07:32:02 +00003051- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003052 start byte and the continuation byte(s) are now considered invalid, instead of
3053 the number of bytes specified by the start byte. E.g.:
3054 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3055 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3056 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3057 returned a single u'\ufffd'.

3101 TypeError instead of giving a DeprecationWarning when a float is parsed using
3102 the 'L' code (for long long). (All other integer codes already raise
3103 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00003113 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

3130 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003131 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3132 (2) The comparison raised an OverflowError for large integers, leading to
3133 unpredictable exceptions when combining integers and complex objects in sets
3134 or dicts.

3438 `va_copy`, but available on all python platforms.
3439
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003440- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3441 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

Antoine Pitrou8689a102010-04-01 16:53:15 +00003452- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003453 function declaration, which was kept for backwards compatibility reasons, is
3454 now removed (the macro was introduced in 1997!).

3464 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3465 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003466 to match the behaviour of the other integer format codes.
3467

Georg Brandl62069d32010-07-31 08:56:11 +00003476- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3477 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3478 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3495 gives improved memory leak detection when running under Valgrind, while taking
3496 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003573 applications that use a lot of regular expressions and limits the impact of
3574 the performance hit anytime the cache is exceeded.

3587 module is renamed to `_datetime` and if available, overrides all classes
3588 defined in datetime with fast C impementation. Python implementation is based
3589 on the original python prototype for the datetime module by Tim Peters with
3590 minor modifications by the PyPy project. The test suite now tests `datetime`
3591 module with and without `_datetime` acceleration using the same test cases.

3806 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
3807 file system encoding with the surrogateescape error handler (instead of
3808 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

3811
Georg Brandl62069d32010-07-31 08:56:11 +00003812- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
3813 messages when accessing undefined class attributes because of the cheap
3814 inheritance with the underlying socket object. The cheap inheritance has been
3815 deprecated.

3818 Patch by Tres Seaver.
3819
Victor Stinnerd17f2192010-08-15 09:56:07 +00003820- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003821 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00003828- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3829 operation raises multiple signals and more than one of those signals is
3830 trapped, the specification determines the order in which the signals should be
3831 handled. In many cases this order wasn't being followed, leading to the wrong
3832 Python exception being raised.

3840
Georg Brandl62069d32010-07-31 08:56:11 +00003841- Issue #8354: The siginterrupt setting is now preserved for all signals, not

3865
Georg Brandl62069d32010-07-31 08:56:11 +00003866- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3867 the method could block indefinitely if called just before the event loop
3868 started running. This also fixes the occasional freezes witnessed in
3869 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00003871- Issue #8524: When creating an SSL socket, the timeout value of the original
3872 socket wasn't retained (instead, a socket with a positive timeout would be
3873 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003874
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003875- Issue #5103: SSL handshake would ignore the socket timeout and block
3876 indefinitely if the other end didn't respond.
3877
Georg Brandl62069d32010-07-31 08:56:11 +00003878- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3879 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00003890- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3891 string "python" as the *ident*. openlog() arguments are all optional and
3892 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003893
Georg Brandl62069d32010-07-31 08:56:11 +00003894- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3895 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003896 wanting to continue using the socket in clear-text mode, by disabling
3897 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003947 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003948 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00003954- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003955 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00003983- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3984 InvalidOperation instead of returning False. (Comparisons involving a quiet
3985 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3986 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003988- Issue #2531: Comparison operations between floats and Decimal instances now
3989 return a result based on the numeric values of the operands; previously they
3990 returned an arbitrary result based on the relative ordering of id(float) and
3991 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3992 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003993
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003994- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003996- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003997 argument `-` which tells it to read files to compile from stdin. Each line is

4006 Fractions instance now raise TypeError instead of returning True/False. This
4007 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4008 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004552 compared to other unix systems. In particular, os.getgroups() does not reflect

4554 information as the id command. os.getgroups() can now return more than 16
4555 groups on MacOSX.

4594 ``datetime.timezone``, return fixed name and UTC offset from their
4595 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

Georg Brandl62069d32010-07-31 08:56:11 +00004624 the result is now always correctly rounded, and is equivalent to ``td /

Mark Dickinson865e01a2009-05-07 16:37:01 +00005203- Issue #5914: Add new C API function PyOS_string_to_double, and
5204 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5205
Eric Smith741191f2009-05-06 13:08:15 +00005206- Issue #3382: float.__format__, complex.__format__, and %-formatting
5207 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

5209
Mark Hammond5a607a32009-05-06 08:04:54 +00005210- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5211 in all operations, including splitdrive, split, etc. splitunc() now issues
5212 a PendingDeprecation warning.
5213
Eric Smith63376222009-05-05 14:04:18 +00005214- Issue #5920: For float.__format__, change the behavior with the
5215 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5216 to be like 'g' but with at least one decimal point and with a
5217 default precision of 12. Previously, the behavior the same but with
5218 a default precision of 6. This more closely matches str(), and
5219 reduces surprises when adding alignment flags to the empty
5220 presentation type. This also affects the new complex.__format__ in
5221 the same way.
5222
Martin v. Löwis011e8422009-05-05 04:43:17 +00005223- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00005225- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5226 shadowed by classtype's, even if it was None. property now
5227 inserts the __doc__ into the subclass instance __dict__.
5228

5231
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005232- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005233
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005234- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5235 received a new method, detach(). detach() disconnects the underlying stream
5236 from the buffer or text IO and returns it.
5237
Mark Dickinson33841c32009-05-01 15:37:04 +00005238- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5239 floats with absolute value over 1e50. Also remove length
5240 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5241 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005242
Eric Smith741191f2009-05-06 13:08:15 +00005243- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005244 format(complex(1, 2./3), '.5') now produces a sensible result.
5245

5247 never gives more than the requested number of significant digits.
5248
Eric Smith6dc46f52009-04-27 20:39:49 +00005249- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5255 titlecase, but not their own uppercase.
5256

5258
Mark Dickinsonad476da2009-04-23 19:14:16 +00005259- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5260 z involves nans, infs or negative zeros.
5261
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005262- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005263
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005264- Issue #1869 (and many duplicates): make round(x, n) correctly
5265 rounded for a float x, by using the decimal <-> binary conversions
5266 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5267 consistently agrees with format(x, '.2f').
5268
Benjamin Petersonae937c02009-04-18 20:54:08 +00005269- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5273
Eric Smith35e84722009-04-16 20:21:28 +00005274- Issue #5515: str.format() type 'n' combined with commas and leading
5275 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005276
5277- Implement PEP 378, Format Specifier for Thousands Separator, for
5278 floats.
5279
Mark Dickinson3370cce2009-04-17 22:40:53 +00005280- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005281 1e11, not 1e12. This avoids printing 13 significant digits in
5282 situations where only 12 of them are correct. Example problem
5283 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5284 long time.)
5285
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005286- Issue #1580: On most platforms, use a 'short' float repr: for a
5287 finite float x, repr(x) now outputs a string based on the shortest
5288 sequence of decimal digits that rounds to x. Previous behaviour was
5289 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005290 Another minor difference is that the new repr switches to
5291 exponential notation at 1e16 instead of the previous 1e17; this
5292 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005293
5294 There's a new sys attribute sys.float_repr_style, which takes
5295 the value 'short' to indicate that we're using short float repr,
5296 and 'legacy' if the short float repr isn't available for one
5297 reason or another.
5298
5299 The float repr change involves incorporating David Gay's 'perfect
5300 rounding' code into the Python core (it's in Python/dtoa.c). As a
5301 secondary consequence, all string-to-float and float-to-string
5302 conversions (including all float formatting operations) will be
5303 correctly rounded on these platforms.
5304
Georg Brandl5f90d792010-08-01 22:31:05 +00005305 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005306 this change does not apply.
5307
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005308- Issue #5759: float() didn't call __float__ on str subclasses.
5309
Georg Brandlabc38772009-04-12 15:51:51 +00005310- The string.maketrans() function is deprecated; there is a new static method
5311 maketrans() on the bytes and bytearray classes. This removes confusion about
5312 the types string.maketrans() is supposed to work with, and mirrors the
5313 methods available on the str class.
5314
R. David Murraydc6da8a2009-04-09 22:16:43 +00005315- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005578 struct.error instead of returning b'\xff\xff\xff\xff'. The
5579 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5580 have been removed from the struct module.

5603
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005604- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5605 rotating the object pointer by 4 bits to the right.
5606
Mark Dickinson87ec0852009-02-09 17:15:59 +00005607- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5608 it now forces its argument to double before testing for infinity.
5609
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005610- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5611 returns a non-number type.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005619
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005620- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005621 were suppressing all exceptions. These include list() and bytearray().

5625
Antoine Pitroub52ec782009-01-25 16:34:23 +00005626- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5627 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5628 evaluation loop is compiled with a new dispatch mechanism which gives
5629 speedups of up to 20%, depending on the system, on various benchmarks.
5630
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005631- Issue #4874: Most builtin decoders now reject unicode input.

5637
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005638- Issue #4838: When a module is deallocated, free the memory backing the
5639 optional module state data.
5640
Mark Dickinson8055afd2009-01-17 10:04:45 +00005641- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005642 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005643
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005644- Issue #4935: The overflow checking code in the expandtabs() method common
5645 to str, bytes and bytearray could be optimized away by the compiler, letting
5646 the interpreter segfault instead of raising an error.
5647
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005648- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5649 __next__ method.
5650
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005651- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5652 function no longer attempt to call the __long__ slot to convert an object
5653 to an integer. Only the __int__ and __trunc__ slots are examined.
5654
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005655- Issue #4893: Use NT threading on CE.
5656

5658
Antoine Pitrouab868312009-01-10 15:40:25 +00005659- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5660 common cases are optimized thanks to a dedicated fast path and a moderate
5661 amount of loop unrolling.
5662
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005663- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5664 collecting the oldest generation) so that allocating lots of objects without
5665 destroying them does not show quadratic performance. Based on a proposal by
5666 Martin von Löwis at
5667 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5668
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005669- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005670 having been closed (for instance, a read() call could return some
5671 previously buffered data). Patch by Dmitry Vasiliev.
5672
Antoine Pitrou05608432009-01-09 18:53:14 +00005673- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5674 flag to work properly. Furthermore, when specifying -u, the text stdout
5675 and stderr streams have line-by-line buffering enabled (the default being
5676 to buffer arbitrary chunks of data).
5677
Raymond Hettinger35631532009-01-09 03:58:09 +00005678- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5679 instead of ints (reducing its size from 4 to 8 times thereby reducing
5680 Python's overall memory).
5681
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005682- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5683 an existing .py counterpart, override the co_filename attributes of all
5684 code objects if the original filename is obsolete (which can happen if the
5685 file has been renamed, moved, or if it is accessed through different paths).
5686 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5687
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005688- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5689 one byte. Also fixes the meaning of len() so that it returns the number of
5690 items, rather than the size in bytes.
5691
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005692- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5693
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005694- Issue #4747: When the terminal does not use utf-8, executing a script with
5695 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5696
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005697- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5698 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005699
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005700- Issue #3680: Reference cycles created through a dict, set or deque iterator
5701 did not get collected.
5702
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005703- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5704 where the tp_hash and tp_dict slots are both NULL.
5705
Georg Brandlccc47b62008-12-28 11:44:14 +00005706- Issue #4759: None is now allowed as the first argument of
5707 bytearray.translate(). It was always allowed for bytes.translate().
5708
Skip Montanaro80072cb2008-12-23 03:51:14 +00005709- Added test case to ensure attempts to read from a file opened for writing
5710 fail.
5711
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005712- Issue #3106: Speedup some comparisons (str/str and int/int).

5716
Antoine Pitrou621601a2008-12-17 23:18:19 +00005717- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5722
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005723- Issue #2173: When getting device encoding, check that return value of
5724 nl_langinfo is not the empty string. This was causing silent build
5725 failures on OS X.
5726
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005727- Issue #4597: Fixed several opcodes that weren't always propagating
5728 exceptions.
5729
5730- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005731 context manager returns a value that cannot be converted to a bool.
5732
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005733- Issue #4445: Replace "sizeof(PyBytesObject)" with
5734 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5735 bytes instances. On a typical machine this saves 3 bytes of memory
5736 (on average) per allocation of a bytes instance.
5737
Christian Heimesa872de52008-12-05 08:26:55 +00005738- Issue #4533: File read operation was dreadfully slow due to a slowly
5739 growing read buffer. Fixed by using the same growth rate algorithm as
5740 Python 2.x.
5741
Antoine Pitrou5504e892008-12-06 21:27:53 +00005742- Issue #4509: Various issues surrounding resize of bytearray objects to
5743 which there are buffer exports (e.g. memoryview instances).
5744
Georg Brandlf9734072008-12-07 15:30:06 +00005745- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5746 method on file objects with closefd=False. The file descriptor is still
5747 kept open but the file object behaves like a closed file. The ``FileIO``
5748 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005749
Antoine Pitroubc420402008-12-07 20:14:49 +00005750- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5751 larger than 1.

5756
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005757- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5758 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5759 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5760 of using the replace error handler in PyUnicode_DecodeUTF8().
