383 environment after Distutils set it. Instead, have Distutils set the the
384 deployment target only in the environment of each build subprocess. It is
385 still possible to globally override the default by setting

387 greater or equal to the default value, the value with which the interpreter
388 was built.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001228- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001229 continuation line in the formatted value has no leading white space and looks
1230 like a header. Since Generator uses Header to format all headers, this check
1231 is made for all headers in any serialized message at serialization time. This
1232 provides protection against header injection attacks.

Éric Araujof0ab5d62011-05-29 03:43:59 +02001241 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001242 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001243
Éric Araujof0ab5d62011-05-29 03:43:59 +02001244- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001245 rfc2047-encoding header values with embedded newlines, leaving them without
1246 folding whitespace. It now uses the continuation_ws, as it does for
1247 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001249- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1250 time.asctime(), time.ctime() and time.strftime() functions will now format
1251 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1252 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1253 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1254 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001886 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002231- Issue #10068: Global objects which have reference cycles with their module's
2232 dict are now cleared again. This causes issue #7140 to appear again.
2233
Victor Stinner257d38f2010-10-09 10:12:11 +00002234- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002235 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002236
Georg Brandl27a28582010-10-10 09:49:21 +00002237- ast.literal_eval() can now handle negative numbers. It is also a little more
2238 liberal in what it accepts without compromising the safety of the evaluation.
2239 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002240
Benjamin Peterson970d1882010-10-02 17:55:47 +00002241- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2242 result metaclasses can now be ABCs (see #9533).
2243
Victor Stinneraef57e32010-10-02 11:50:49 +00002244- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2245
Victor Stinner5593d8a2010-10-02 11:11:27 +00002246- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002247 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2248 32 bits wchar_t (eg. Linux in narrow build).

2254
Brett Cannon5305a992010-09-27 21:08:38 +00002255- Issue #7397: Mention that importlib.import_module() is probably what someone
2256 really wants to be using in __import__'s docstring.
2257
Georg Brandl27a28582010-10-10 09:49:21 +00002258- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2259 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002261- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002262 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002264- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2265
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002266- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2267 threads are still running. Instead, reinitialize the GIL on a second call to
2268 Py_Initialize().
2269
Georg Brandl27a28582010-10-10 09:49:21 +00002270- All SyntaxErrors now have a column offset and therefore a caret when the error
2271 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002272
Brett Cannonbc2eff32010-09-19 21:39:02 +00002273- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2274 module that was imported, but instead gets the module from sys.modules.
2275
Nick Coghlan37ee8502010-12-03 14:26:13 +00002276- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002277 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002278
Georg Brandl27a28582010-10-10 09:49:21 +00002279- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2280 with a non-empty format string. This is an effort to future-proof user
2281 code. If a derived class does not currently implement __format__ but later
2282 adds its own __format__, it would most likely break user code that had
2283 supplied a format string. This will be changed to a DeprecationWaring in
2284 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002285
Antoine Pitrou1df15362010-09-13 14:16:46 +00002286- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2287 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2288 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2289
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002290- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2291 functions from the libc caused the methods .upper() and lower() to become
2292 locale aware and created subtly wrong results.
2293
Georg Brandl27a28582010-10-10 09:49:21 +00002294- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2295 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002296
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002297- Issue #4617: Previously it was illegal to delete a name from the local
2298 namespace if it occurs as a free variable in a nested block. This limitation
2299 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2300
Georg Brandl27a28582010-10-10 09:49:21 +00002301- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2302 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2303 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2304 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002305
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002306- Issue #9757: memoryview objects get a release() method to release the
2307 underlying buffer (previously this was only done when deallocating the
2308 memoryview), and gain support for the context management protocol.
2309
Antoine Pitrou079ce542010-09-08 12:37:10 +00002310- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2311 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002327- Issue #4661: email can now parse bytes input and generate either converted
2328 7bit output or bytes output. Email version bumped to 5.1.0.
2329
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002330- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2335
Éric Araujo6108bf52010-10-04 23:52:37 +00002336- Issue #9042: Fix interaction of custom translation classes and caching in
2337 gettext.
2338
Éric Araujoef777bd2010-10-05 00:04:20 +00002339- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002340 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002341 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002342 replacement for old handle_accept() and avoids the user to call accept()
2343 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002345- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002366- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002367 retry the select() loop instead of bailing out. This is because select() can
2368 incorrectly report a socket as ready for reading (for example, if it received
2369 some data with an invalid checksum).

Antoine Pitrou98b46702010-09-18 22:59:00 +00002415- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002416 non-blocking mode: they return None when an operation would block (instead of
2417 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002418
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002419- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Antoine Pitrou328ec742010-09-14 18:37:24 +00002428
Georg Brandl27a28582010-10-10 09:49:21 +00002429- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2430 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002449- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002450 it possible for the user to create self-referencing ordered dictionaries which
2451 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002452 approach of using weakref proxies so that reference cycles never get created
2453 in the first place.
2454
Victor Stinnercb043522010-09-10 23:49:04 +00002455- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2456 encode the value with filesystem encoding and surrogateescape (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002459- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2460 environment variable to set the filesystem encoding at Python startup.
2461 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2462 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002464- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00002471- Logging: Added QueueHandler class to facilitate logging usage with
2472 multiprocessing.
2473
Georg Brandl27a28582010-10-10 09:49:21 +00002474- Issue #9707: Rewritten reference implementation of threading.local which is
2475 friendlier towards reference cycles. This change is not normally visible
2476 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002477
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002478- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2479 still return the id of the parent process after it has exited. This process
2480 id may even have been reused by another unrelated process.
2481
Georg Brandl27a28582010-10-10 09:49:21 +00002482- Issue #9792: In case of connection failure, socket.create_connection() would
2483 swallow the exception and raise a new one, making it impossible to fetch the
2484 original errno, or to filter timeout errors. Now the original error is
2485 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002487- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2488 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2489 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002491- Updates to the random module:
2492
Georg Brandl27a28582010-10-10 09:49:21 +00002493 * Document which parts of the module are guaranteed to stay the same across
2494 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002496 * Update the seed() method to use all of the bits in a string instead of just
2497 the hash value. This makes better use of the seed value and assures the
2498 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002499
Georg Brandl27a28582010-10-10 09:49:21 +00002500 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2501 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2502 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002503
2504 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002523- hashlib has two new constant attributes: algorithms_guaranteed and
2524 algorithms_avaiable that respectively list the names of hash algorithms
2525 guaranteed to exist in all Python implementations and the names of hash
2526 algorithms available in the current process.
2527

Georg Brandl649971e2010-09-05 17:06:50 +00002618- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2619 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

2653
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002654- Issue #5127: The C functions that access the Unicode Database now accept and
2655 return characters from the full Unicode range, even on narrow unicode builds
2656 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2657 in Python is that unicodedata.numeric() now returns the correct value for

Ezio Melotti57221d02010-07-01 07:32:02 +00003038- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003039 start byte and the continuation byte(s) are now considered invalid, instead of
3040 the number of bytes specified by the start byte. E.g.:
3041 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3042 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3043 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3044 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003074- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003075 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003087- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3088 TypeError instead of giving a DeprecationWarning when a float is parsed using
3089 the 'L' code (for long long). (All other integer codes already raise
3090 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003091
Victor Stinner600d3be2010-06-10 12:00:55 +00003092- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3094 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3095
Georg Brandl62069d32010-07-31 08:56:11 +00003096- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3097 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003098
3099- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003100 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003101 like bytearray.
3102
Georg Brandl62069d32010-07-31 08:56:11 +00003103- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003104 used anymore and it was never documented.
3105

Georg Brandl62069d32010-07-31 08:56:11 +00003111- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3112 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3113 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3114 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003115
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003116- Issue #8748: Fix two issues with comparisons between complex and integer
3117 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003118 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3119 (2) The comparison raised an OverflowError for large integers, leading to

Georg Brandl62069d32010-07-31 08:56:11 +00003251 where the right hand operand is a set of constants, by turning the set into a
3252 frozenset and pre-building it as a constant. The comparison operation is made
3253 against the constant instead of building a new set each time it is executed (a
3254 similar optimization already existed which turned a list of constants into a
3255 pre-built tuple). Patch and additional tests by Dave Malcolm.

3426
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003427- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3428 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3451 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3452 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003453 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003463- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3464 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3465 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3482 gives improved memory leak detection when running under Valgrind, while taking
3483 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003560 applications that use a lot of regular expressions and limits the impact of
3561 the performance hit anytime the cache is exceeded.

Victor Stinnerd17f2192010-08-15 09:56:07 +00003807- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003808 (instead of replace in read mode or strict in write mode).
Victor Stinnerde629d42010-05-05 21:43:57 +00003809
Barry Warsaw83d89982010-05-05 16:18:31 +00003810- Issue #7755: Use an unencumbered audio file for tests.

3813 and any children created using ``os.fork`` on MacOS X 10.6.
Ronald Oussorenac764d32010-05-05 15:32:33 +00003814
Georg Brandl62069d32010-07-31 08:56:11 +00003815- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3816 operation raises multiple signals and more than one of those signals is
3817 trapped, the specification determines the order in which the signals should be
3818 handled. In many cases this order wasn't being followed, leading to the wrong
3819 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00003820
Antoine Pitrou6be88762010-05-03 16:48:20 +00003821- Issue #7865: The close() method of :mod:`io` objects should not swallow
Georg Brandl62069d32010-07-31 08:56:11 +00003822 exceptions raised by the implicit flush(). Also qensure that calling close()
3823 several times is supported. Patch by Pascal Chambon.

3826 gc.DEBUG_STATS.
3827
Georg Brandl62069d32010-07-31 08:56:11 +00003828- Issue #8354: The siginterrupt setting is now preserved for all signals, not
3829 just SIGCHLD.
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +00003830

Ronald Oussoren4d39f6e2010-05-02 09:54:35 +00003832 webbrowser.get("safari").
3833
Georg Brandl62069d32010-07-31 08:56:11 +00003834- Issue #8464: tarfile no longer creates files with execute permissions set when

3843 It should correctly return an empty response now.
3844
Benjamin Peterson95e392c2010-04-27 21:07:21 +00003845- Issue #8546: Reject None given as the buffering argument to _pyio.open.

Georg Brandl62069d32010-07-31 08:56:11 +00003853- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3854 the method could block indefinitely if called just before the event loop
3855 started running. This also fixes the occasional freezes witnessed in
3856 test_httpservers.
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00003857
Georg Brandl62069d32010-07-31 08:56:11 +00003858- Issue #8524: When creating an SSL socket, the timeout value of the original
3859 socket wasn't retained (instead, a socket with a positive timeout would be
3860 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003861
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003862- Issue #5103: SSL handshake would ignore the socket timeout and block
3863 indefinitely if the other end didn't respond.
3864
Georg Brandl62069d32010-07-31 08:56:11 +00003865- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3866 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003867
Georg Brandl62069d32010-07-31 08:56:11 +00003868- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Victor Stinner349fd522010-04-23 10:56:17 +00003876
Georg Brandl62069d32010-07-31 08:56:11 +00003877- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3878 string "python" as the *ident*. openlog() arguments are all optional and
3879 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003880
Georg Brandl62069d32010-07-31 08:56:11 +00003881- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3882 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003883 wanting to continue using the socket in clear-text mode, by disabling
3884 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
3885
Antoine Pitrou7062db82010-04-22 13:30:10 +00003886- Issue #8496: make mailcap.lookup() always return a list, rather than an

3893 extension, such that verification of some SSL certificates doesn't fail
3894 because of an "unknown algorithm".
Antoine Pitroufec12ff2010-04-21 19:46:23 +00003895

3918 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
3919
Victor Stinner0e59cc32010-04-16 23:49:32 +00003920- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

3932
Georg Brandl62069d32010-07-31 08:56:11 +00003933- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003934 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003935 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003936
Victor Stinner485fb562010-04-13 11:07:24 +00003937- Issue #8383: pickle and pickletools use surrogatepass error handler when
3938 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00003939 Python 2.x and 3.x.
Victor Stinner485fb562010-04-13 11:07:24 +00003940
R. David Murrayb2416e52010-04-12 16:58:02 +00003941- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003942 filename and date, conforming to the 'standards' they were originally designed
3943 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00003944
R. David Murrayef3d6bd2010-04-12 14:48:58 +00003945- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Georg Brandl62069d32010-07-31 08:56:11 +00003956 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3957 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00003958
Raymond Hettingerc50846a2010-04-05 18:56:31 +00003959- Add functools.total_ordering() and functools.cmp_to_key().
3960
Georg Brandl62069d32010-07-31 08:56:11 +00003961- Issue #8257: The Decimal construct now accepts a float instance directly,
3962 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003963
3964 >>> Decimal(1.1)
3965 Decimal('1.100000000000000088817841970012523233890533447265625')
3966

Georg Brandl62069d32010-07-31 08:56:11 +00003970- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3971 InvalidOperation instead of returning False. (Comparisons involving a quiet
3972 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3973 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003974
Georg Brandl62069d32010-07-31 08:56:11 +00003975- Issue #2531: Comparison operations between floats and Decimal instances now
3976 return a result based on the numeric values of the operands; previously they
3977 returned an arbitrary result based on the relative ordering of id(float) and
3978 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3979 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003980
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003981- Added a subtract() method to collections.Counter().
3982
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003983- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003984 argument `-` which tells it to read files to compile from stdin. Each line is
3985 read on demand and the named file is compiled immediately. (Original patch by
3986 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003987
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003988- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3989 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003990 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

3993 Fractions instance now raise TypeError instead of returning True/False. This
3994 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3995 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003997- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Georg Brandl62069d32010-07-31 08:56:11 +00004005 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4006 silenced.

Antoine Pitrou3c0fac22010-03-26 19:36:14 +00004011- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4012 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4013 reads and writes are always retried by OpenSSL itself.

4039 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4040 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004042- subprocess.Popen now has restore_signals and start_new_session features. The
4043 default of restore_signals=True is a new behavior compared to earlier Python
4044 versions. This means that signals such as SIGPIPE are not ignored by default
4045 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004322 default when instantiating a `threading.RLock` object. This makes recursive
4323 locks as fast as regular non-recursive locks (previously, they were slower by
4324 10x to 15x).

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004533- Issue #9959: Tweak formula used for computing math.log of an integer,
4534 making it marginally more accurate for exact powers of 2.

4537
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004538- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004539 compared to other unix systems. In particular, os.getgroups() does not reflect
4540 any changes made using os.setgroups() but basicly always returns the same
4541 information as the id command. os.getgroups() can now return more than 16
4542 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004567- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4568 Prior to this change, timezone adjustment in utctimetuple() could produce
4569 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4570 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004572- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4573 directive. When the ``%z`` directive is present in the format string, an
4574 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4575 ``datetime.timezone`` instance constructed from the parsed offset. If both
4576 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4577 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004578
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004579- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004580 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4581 ``datetime.timezone``, return fixed name and UTC offset from their
4582 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4583 returns ``None``. A class attribute, ``utc`` contains an instance
4584 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004600- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4601 with an improved 'binary-split' algorithm that uses fewer multiplications and
4602 allows many of the multiplications to be performed using plain C integer
4603 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4604 arguments.

4608
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004609- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4610 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004611 the result is now always correctly rounded, and is equivalent to ``td /
4612 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004620- Issue #8300: When passing a non-integer argument to struct.pack with any
4621 integer format code, struct.pack first attempts to convert the non-integer
4622 using its __index__ method. If that method is non-existent or raises
4623 TypeError it goes on to try the __int__ method, as described below.
4624

5004 are always None now.
5005
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005006- Issue #6137: The pickle module now translates module names when loading
5007 or dumping pickles with a 2.x-compatible protocol, in order to make data
5008 sharing and migration easier. This behaviour can be disabled using the
5009 new `fix_imports` optional argument.

5064 that would raise SystemError.
5065
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005066- Issue #5982: staticmethod and classmethod now expose the wrapped
5067 function with __func__.
5068
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005069- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005072- Issue #5829: complex("1e500") no longer raises OverflowError. This
5073 makes it consistent with float("1e500") and interpretation of real
5074 and imaginary literals.
5075
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005076- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005080- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5081 (1) inf and nan strings with trailing whitespace were incorrectly
5082 rejected; (2) parsing of strings representing infinities and nans
5083 was locale aware; and (3) the interpretation of fromhex('-nan')
5084 didn't match that of float('-nan').

5101
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005102- In unittest, using a skipping decorator on a class is now equivalent to
5103 skipping every test on the class. The ClassTestSuite class has been removed.
5104
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005105- Issue #6050: Don't fail extracting a directory from a zipfile if
5106 the directory already exists.
5107
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005108- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5109 than an int, which makes some operations possible under 64-bit Linux (e.g.
5110 DN_MULTISHOT with F_NOTIFY).
5111
Antoine Pitrou716c4442009-05-23 19:04:03 +00005112- Issue #5761: Add the name of the underlying file to the repr() of various
5113 IO objects.
5114
R. David Murraycaa27b72009-05-23 18:49:56 +00005115- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5116 by Musashi Tamura, tests by Marcin Bachry.
5117
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005118- Issue #1983: Fix functions taking or returning a process identifier to use
5119 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5120 a process identifier type wider than the standard C integer type.
5121
R. David Murray87e20742009-05-23 01:30:26 +00005122- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5133
Antoine Pitroue4501852009-05-14 18:55:55 +00005134- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5135 library. This means, for example, that opening an UTF-16 text file in
5136 append mode doesn't add a BOM at the end of the file if the file isn't
5137 empty.
5138
R. David Murray74b89242009-05-13 17:33:03 +00005139- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5140 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5141 corrects a pydoc regression.
5142
Georg Brandl5f90d792010-08-01 22:31:05 +00005143- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005144 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005186
5187Core and Builtins
5188-----------------
5189
Mark Dickinson865e01a2009-05-07 16:37:01 +00005190- Issue #5914: Add new C API function PyOS_string_to_double, and
5191 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5192
Eric Smith741191f2009-05-06 13:08:15 +00005193- Issue #3382: float.__format__, complex.__format__, and %-formatting
5194 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5195 affects nan -> NAN and inf -> INF.
5196
Mark Hammond5a607a32009-05-06 08:04:54 +00005197- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5198 in all operations, including splitdrive, split, etc. splitunc() now issues
5199 a PendingDeprecation warning.
5200
Eric Smith63376222009-05-05 14:04:18 +00005201- Issue #5920: For float.__format__, change the behavior with the
5202 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5203 to be like 'g' but with at least one decimal point and with a
5204 default precision of 12. Previously, the behavior the same but with
5205 a default precision of 6. This more closely matches str(), and
5206 reduces surprises when adding alignment flags to the empty
5207 presentation type. This also affects the new complex.__format__ in
5208 the same way.
5209
Martin v. Löwis011e8422009-05-05 04:43:17 +00005210- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5211
R. David Murrayb18500d2009-05-04 22:59:07 +00005212- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5213 shadowed by classtype's, even if it was None. property now
5214 inserts the __doc__ into the subclass instance __dict__.
5215
Antoine Pitrou244651a2009-05-04 18:56:13 +00005216- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5217 sequences. Patch by Nick Barnes and Victor Stinner.
5218
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005219- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005220
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005221- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5222 received a new method, detach(). detach() disconnects the underlying stream
5223 from the buffer or text IO and returns it.
5224
Mark Dickinson33841c32009-05-01 15:37:04 +00005225- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5226 floats with absolute value over 1e50. Also remove length
5227 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5228 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005229
Eric Smith741191f2009-05-06 13:08:15 +00005230- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005231 format(complex(1, 2./3), '.5') now produces a sensible result.
5232
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005233- Issue #5864: Fix empty format code formatting for floats so that it
5234 never gives more than the requested number of significant digits.
5235
Eric Smith6dc46f52009-04-27 20:39:49 +00005236- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5237 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5238
Eric Smithcc32a112009-04-26 21:35:14 +00005239- Issue #5835: Deprecate PyOS_ascii_formatd.
5240
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005241- Issue #4971: Fix titlecase for characters that are their own
5242 titlecase, but not their own uppercase.
5243
Benjamin Peterson193152c2009-04-25 01:08:45 +00005244- Issue #5283: Setting __class__ in __del__ caused a segfault.
5245
Mark Dickinsonad476da2009-04-23 19:14:16 +00005246- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5247 z involves nans, infs or negative zeros.
5248
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005249- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005250
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005251- Issue #1869 (and many duplicates): make round(x, n) correctly
5252 rounded for a float x, by using the decimal <-> binary conversions
5253 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5254 consistently agrees with format(x, '.2f').
5255
Benjamin Petersonae937c02009-04-18 20:54:08 +00005256- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5257 some builtin types.
5258
Eric Smith0923d1d2009-04-16 20:16:10 +00005259- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5260
Eric Smith35e84722009-04-16 20:21:28 +00005261- Issue #5515: str.format() type 'n' combined with commas and leading
5262 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005263
5264- Implement PEP 378, Format Specifier for Thousands Separator, for
5265 floats.
5266
Mark Dickinson3370cce2009-04-17 22:40:53 +00005267- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005268 1e11, not 1e12. This avoids printing 13 significant digits in
5269 situations where only 12 of them are correct. Example problem
5270 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5271 long time.)
5272
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005273- Issue #1580: On most platforms, use a 'short' float repr: for a
5274 finite float x, repr(x) now outputs a string based on the shortest
5275 sequence of decimal digits that rounds to x. Previous behaviour was
5276 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005277 Another minor difference is that the new repr switches to
5278 exponential notation at 1e16 instead of the previous 1e17; this
5279 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005280
5281 There's a new sys attribute sys.float_repr_style, which takes
5282 the value 'short' to indicate that we're using short float repr,
5283 and 'legacy' if the short float repr isn't available for one
5284 reason or another.
5285
5286 The float repr change involves incorporating David Gay's 'perfect
5287 rounding' code into the Python core (it's in Python/dtoa.c). As a
5288 secondary consequence, all string-to-float and float-to-string
5289 conversions (including all float formatting operations) will be
5290 correctly rounded on these platforms.

5296
Georg Brandlabc38772009-04-12 15:51:51 +00005297- The string.maketrans() function is deprecated; there is a new static method
5298 maketrans() on the bytes and bytearray classes. This removes confusion about
5299 the types string.maketrans() is supposed to work with, and mirrors the
5300 methods available on the str class.

5581
Eric Smith5e5c0db2009-02-20 14:25:03 +00005582- Issue #5247: Improve error message when unknown format codes are
5583 used when using str.format() with str, int, and float arguments.
5584
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005585- Issue #5249: time.strftime returned malformed string when format string
5586 contained non ascii character on windows.
5587
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005588- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5589 source has already been decoded into str.
5590
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005591- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5592 rotating the object pointer by 4 bits to the right.
5593
Mark Dickinson87ec0852009-02-09 17:15:59 +00005594- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5595 it now forces its argument to double before testing for infinity.
5596
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005597- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5598 returns a non-number type.
5599
Benjamin Peterson87618552009-02-08 15:00:52 +00005600- Issue #5182: Removed memoryview.__str__.
5601
Mark Dickinsonc008a172009-02-01 13:59:22 +00005602- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5603 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005604 the type definition cmpfunc. The tp_compare slot has been renamed
5605 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005606
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005607- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005608 were suppressing all exceptions. These include list() and bytearray().
5609
Mark Dickinson1124e712009-01-28 21:25:58 +00005610- Issue #4707: round(x, n) now returns an integer if x is an integer.
5611 Previously it returned a float.
5612
Antoine Pitroub52ec782009-01-25 16:34:23 +00005613- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5614 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5615 evaluation loop is compiled with a new dispatch mechanism which gives
5616 speedups of up to 20%, depending on the system, on various benchmarks.
5617
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005618- Issue #4874: Most builtin decoders now reject unicode input.

5626 optional module state data.
5627
Mark Dickinson8055afd2009-01-17 10:04:45 +00005628- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005629 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005630
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005631- Issue #4935: The overflow checking code in the expandtabs() method common
5632 to str, bytes and bytearray could be optimized away by the compiler, letting
5633 the interpreter segfault instead of raising an error.
5634
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005635- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5636 __next__ method.
5637
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005638- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5639 function no longer attempt to call the __long__ slot to convert an object
5640 to an integer. Only the __int__ and __trunc__ slots are examined.
5641
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005642- Issue #4893: Use NT threading on CE.
5643

5645
Antoine Pitrouab868312009-01-10 15:40:25 +00005646- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5647 common cases are optimized thanks to a dedicated fast path and a moderate
5648 amount of loop unrolling.
5649
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005650- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5651 collecting the oldest generation) so that allocating lots of objects without
5652 destroying them does not show quadratic performance. Based on a proposal by
5653 Martin von Löwis at
5654 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5655
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005656- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005657 having been closed (for instance, a read() call could return some
5658 previously buffered data). Patch by Dmitry Vasiliev.
5659
Antoine Pitrou05608432009-01-09 18:53:14 +00005660- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5661 flag to work properly. Furthermore, when specifying -u, the text stdout
5662 and stderr streams have line-by-line buffering enabled (the default being
5663 to buffer arbitrary chunks of data).
5664
Raymond Hettinger35631532009-01-09 03:58:09 +00005665- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5666 instead of ints (reducing its size from 4 to 8 times thereby reducing
5667 Python's overall memory).
5668
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005669- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5670 an existing .py counterpart, override the co_filename attributes of all
5671 code objects if the original filename is obsolete (which can happen if the
5672 file has been renamed, moved, or if it is accessed through different paths).
5673 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5674
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005675- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5676 one byte. Also fixes the meaning of len() so that it returns the number of
5677 items, rather than the size in bytes.
5678
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005679- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5680
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005681- Issue #4747: When the terminal does not use utf-8, executing a script with
5682 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5683
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005684- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5685 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005686
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005687- Issue #3680: Reference cycles created through a dict, set or deque iterator
5688 did not get collected.
5689
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005690- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5691 where the tp_hash and tp_dict slots are both NULL.
5692
Georg Brandlccc47b62008-12-28 11:44:14 +00005693- Issue #4759: None is now allowed as the first argument of
5694 bytearray.translate(). It was always allowed for bytes.translate().
5695
Skip Montanaro80072cb2008-12-23 03:51:14 +00005696- Added test case to ensure attempts to read from a file opened for writing
5697 fail.
5698
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005699- Issue #3106: Speedup some comparisons (str/str and int/int).

5702 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5703
Antoine Pitrou621601a2008-12-17 23:18:19 +00005704- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5705 print elapsed times, not only when some objects are uncollectable /
5706 unreachable. Original patch by Neil Schemenauer.
5707
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005708- Issue #3439: Add a bit_length method to int.
5709
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005710- Issue #2173: When getting device encoding, check that return value of
5711 nl_langinfo is not the empty string. This was causing silent build
5712 failures on OS X.
5713
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005714- Issue #4597: Fixed several opcodes that weren't always propagating
5715 exceptions.
5716
5717- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005718 context manager returns a value that cannot be converted to a bool.
5719
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005720- Issue #4445: Replace "sizeof(PyBytesObject)" with
5721 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5722 bytes instances. On a typical machine this saves 3 bytes of memory
5723 (on average) per allocation of a bytes instance.
5724
Christian Heimesa872de52008-12-05 08:26:55 +00005725- Issue #4533: File read operation was dreadfully slow due to a slowly
5726 growing read buffer. Fixed by using the same growth rate algorithm as
5727 Python 2.x.
5728
Antoine Pitrou5504e892008-12-06 21:27:53 +00005729- Issue #4509: Various issues surrounding resize of bytearray objects to
5730 which there are buffer exports (e.g. memoryview instances).
5731
Georg Brandlf9734072008-12-07 15:30:06 +00005732- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5733 method on file objects with closefd=False. The file descriptor is still
5734 kept open but the file object behaves like a closed file. The ``FileIO``
5735 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005736
Antoine Pitroubc420402008-12-07 20:14:49 +00005737- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5738 larger than 1.

5743
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005744- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5745 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5746 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5747 of using the replace error handler in PyUnicode_DecodeUTF8().
