382 environment after Distutils set it. Instead, have Distutils set the the

384 still possible to globally override the default by setting
385 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
386 greater or equal to the default value, the value with which the interpreter
387 was built.

1230 is made for all headers in any serialized message at serialization time. This
1231 provides protection against header injection attacks.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001885 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002230- Issue #10068: Global objects which have reference cycles with their module's
2231 dict are now cleared again. This causes issue #7140 to appear again.
2232
Victor Stinner257d38f2010-10-09 10:12:11 +00002233- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002234 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002235
Georg Brandl27a28582010-10-10 09:49:21 +00002236- ast.literal_eval() can now handle negative numbers. It is also a little more
2237 liberal in what it accepts without compromising the safety of the evaluation.
2238 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002239
Benjamin Peterson970d1882010-10-02 17:55:47 +00002240- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2241 result metaclasses can now be ABCs (see #9533).
2242
Victor Stinneraef57e32010-10-02 11:50:49 +00002243- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2244
Victor Stinner5593d8a2010-10-02 11:11:27 +00002245- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002246 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2247 32 bits wchar_t (eg. Linux in narrow build).

Brett Cannon5305a992010-09-27 21:08:38 +00002254- Issue #7397: Mention that importlib.import_module() is probably what someone

2256
Georg Brandl27a28582010-10-10 09:49:21 +00002257- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002260- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002261 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002263- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2264
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002265- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2266 threads are still running. Instead, reinitialize the GIL on a second call to
2267 Py_Initialize().
2268
Georg Brandl27a28582010-10-10 09:49:21 +00002269- All SyntaxErrors now have a column offset and therefore a caret when the error
2270 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002271
Brett Cannonbc2eff32010-09-19 21:39:02 +00002272- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2273 module that was imported, but instead gets the module from sys.modules.
2274
Nick Coghlan37ee8502010-12-03 14:26:13 +00002275- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002276 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002277
Georg Brandl27a28582010-10-10 09:49:21 +00002278- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2279 with a non-empty format string. This is an effort to future-proof user
2280 code. If a derived class does not currently implement __format__ but later
2281 adds its own __format__, it would most likely break user code that had
2282 supplied a format string. This will be changed to a DeprecationWaring in
2283 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002284
Antoine Pitrou1df15362010-09-13 14:16:46 +00002285- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2286 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2287 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2288
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002289- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2290 functions from the libc caused the methods .upper() and lower() to become
2291 locale aware and created subtly wrong results.
2292
Georg Brandl27a28582010-10-10 09:49:21 +00002293- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2294 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002295
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002296- Issue #4617: Previously it was illegal to delete a name from the local
2297 namespace if it occurs as a free variable in a nested block. This limitation
2298 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2299
Georg Brandl27a28582010-10-10 09:49:21 +00002300- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2301 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2302 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2303 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002304
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002305- Issue #9757: memoryview objects get a release() method to release the
2306 underlying buffer (previously this was only done when deallocating the
2307 memoryview), and gain support for the context management protocol.
2308
Antoine Pitrou079ce542010-09-08 12:37:10 +00002309- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2310 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002326- Issue #4661: email can now parse bytes input and generate either converted

2328
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002329- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2336 gettext.
2337
Éric Araujoef777bd2010-10-05 00:04:20 +00002338- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002339 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002340 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002341 replacement for old handle_accept() and avoids the user to call accept()
2342 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002365- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002366 retry the select() loop instead of bailing out. This is because select() can
2367 incorrectly report a socket as ready for reading (for example, if it received
2368 some data with an invalid checksum).

Antoine Pitrou98b46702010-09-18 22:59:00 +00002414- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002415 non-blocking mode: they return None when an operation would block (instead of
2416 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002417
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002418- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00002425- Issue #9854: The default read() implementation in io.RawIOBase now handles
2426 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002427
Georg Brandl27a28582010-10-10 09:49:21 +00002428- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2429 supporting the whole socket API (rather than the "raw" _socket.socket
2430 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002431

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002448- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002449 it possible for the user to create self-referencing ordered dictionaries which
2450 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002451 approach of using weakref proxies so that reference cycles never get created
2452 in the first place.
2453
Victor Stinnercb043522010-09-10 23:49:04 +00002454- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2455 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002456 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002458- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2459 environment variable to set the filesystem encoding at Python startup.
2460 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2461 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002463- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00002467- The pprint module now supports printing OrderedDicts in their given order
2468 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002470- Logging: Added QueueHandler class to facilitate logging usage with
2471 multiprocessing.
2472
Georg Brandl27a28582010-10-10 09:49:21 +00002473- Issue #9707: Rewritten reference implementation of threading.local which is
2474 friendlier towards reference cycles. This change is not normally visible
2475 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002476
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002477- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2478 still return the id of the parent process after it has exited. This process
2479 id may even have been reused by another unrelated process.
2480
Georg Brandl27a28582010-10-10 09:49:21 +00002481- Issue #9792: In case of connection failure, socket.create_connection() would
2482 swallow the exception and raise a new one, making it impossible to fetch the
2483 original errno, or to filter timeout errors. Now the original error is
2484 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002486- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2487 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2488 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002490- Updates to the random module:
2491
Georg Brandl27a28582010-10-10 09:49:21 +00002492 * Document which parts of the module are guaranteed to stay the same across
2493 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002494
Georg Brandl27a28582010-10-10 09:49:21 +00002495 * Update the seed() method to use all of the bits in a string instead of just
2496 the hash value. This makes better use of the seed value and assures the
2497 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002498
Georg Brandl27a28582010-10-10 09:49:21 +00002499 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2500 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2501 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002502
2503 * Improved documentation of arguments to randrange(). Issue #9379.

2509 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2510 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002522- hashlib has two new constant attributes: algorithms_guaranteed and
2523 algorithms_avaiable that respectively list the names of hash algorithms
2524 guaranteed to exist in all Python implementations and the names of hash
2525 algorithms available in the current process.
2526
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002527- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002617- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2618 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002630- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2631 now removed, since their effect was inexistent in 3.x (the default encoding is

2652
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002653- Issue #5127: The C functions that access the Unicode Database now accept and
2654 return characters from the full Unicode range, even on narrow unicode builds
2655 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2656 in Python is that unicodedata.numeric() now returns the correct value for

Ezio Melotti57221d02010-07-01 07:32:02 +00003037- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003038 start byte and the continuation byte(s) are now considered invalid, instead of
3039 the number of bytes specified by the start byte. E.g.:
3040 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3041 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3042 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3043 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003086- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3087 TypeError instead of giving a DeprecationWarning when a float is parsed using
3088 the 'L' code (for long long). (All other integer codes already raise
3089 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003090
Victor Stinner600d3be2010-06-10 12:00:55 +00003091- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3093 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3094
Georg Brandl62069d32010-07-31 08:56:11 +00003095- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3096 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003097

Georg Brandl62069d32010-07-31 08:56:11 +00003099 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003100 like bytearray.
3101
Georg Brandl62069d32010-07-31 08:56:11 +00003102- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

Georg Brandl62069d32010-07-31 08:56:11 +00003110- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3111 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3112 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3113 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003114
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003115- Issue #8748: Fix two issues with comparisons between complex and integer
3116 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003117 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3118 (2) The comparison raised an OverflowError for large integers, leading to

Georg Brandl62069d32010-07-31 08:56:11 +00003250 where the right hand operand is a set of constants, by turning the set into a
3251 frozenset and pre-building it as a constant. The comparison operation is made
3252 against the constant instead of building a new set each time it is executed (a
3253 similar optimization already existed which turned a list of constants into a
3254 pre-built tuple). Patch and additional tests by Dave Malcolm.

3281 least on IEEE 754 platforms), and in particular does not depend on the

3425
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003426- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3427 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3450 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3451 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003452 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003462- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3463 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3464 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3481 gives improved memory leak detection when running under Valgrind, while taking
3482 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003559 applications that use a lot of regular expressions and limits the impact of
3560 the performance hit anytime the cache is exceeded.

Victor Stinnerd17f2192010-08-15 09:56:07 +00003806- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003807 (instead of replace in read mode or strict in write mode).
Victor Stinnerde629d42010-05-05 21:43:57 +00003808
Barry Warsaw83d89982010-05-05 16:18:31 +00003809- Issue #7755: Use an unencumbered audio file for tests.

3812 and any children created using ``os.fork`` on MacOS X 10.6.
Ronald Oussorenac764d32010-05-05 15:32:33 +00003813
Georg Brandl62069d32010-07-31 08:56:11 +00003814- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3815 operation raises multiple signals and more than one of those signals is
3816 trapped, the specification determines the order in which the signals should be
3817 handled. In many cases this order wasn't being followed, leading to the wrong
3818 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00003819
Antoine Pitrou6be88762010-05-03 16:48:20 +00003820- Issue #7865: The close() method of :mod:`io` objects should not swallow
Georg Brandl62069d32010-07-31 08:56:11 +00003821 exceptions raised by the implicit flush(). Also qensure that calling close()
3822 several times is supported. Patch by Pascal Chambon.

3825 gc.DEBUG_STATS.
3826
Georg Brandl62069d32010-07-31 08:56:11 +00003827- Issue #8354: The siginterrupt setting is now preserved for all signals, not
3828 just SIGCHLD.
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +00003829

Ronald Oussoren4d39f6e2010-05-02 09:54:35 +00003831 webbrowser.get("safari").
3832
Georg Brandl62069d32010-07-31 08:56:11 +00003833- Issue #8464: tarfile no longer creates files with execute permissions set when

3842 It should correctly return an empty response now.
3843
Benjamin Peterson95e392c2010-04-27 21:07:21 +00003844- Issue #8546: Reject None given as the buffering argument to _pyio.open.

Georg Brandl62069d32010-07-31 08:56:11 +00003852- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3853 the method could block indefinitely if called just before the event loop
3854 started running. This also fixes the occasional freezes witnessed in
3855 test_httpservers.
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00003856
Georg Brandl62069d32010-07-31 08:56:11 +00003857- Issue #8524: When creating an SSL socket, the timeout value of the original
3858 socket wasn't retained (instead, a socket with a positive timeout would be
3859 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003860
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003861- Issue #5103: SSL handshake would ignore the socket timeout and block
3862 indefinitely if the other end didn't respond.
3863
Georg Brandl62069d32010-07-31 08:56:11 +00003864- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3865 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003866
Georg Brandl62069d32010-07-31 08:56:11 +00003867- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Victor Stinner349fd522010-04-23 10:56:17 +00003875
Georg Brandl62069d32010-07-31 08:56:11 +00003876- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3877 string "python" as the *ident*. openlog() arguments are all optional and
3878 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003879
Georg Brandl62069d32010-07-31 08:56:11 +00003880- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3881 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003882 wanting to continue using the socket in clear-text mode, by disabling
3883 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
3884
Antoine Pitrou7062db82010-04-22 13:30:10 +00003885- Issue #8496: make mailcap.lookup() always return a list, rather than an

3892 extension, such that verification of some SSL certificates doesn't fail
3893 because of an "unknown algorithm".
Antoine Pitroufec12ff2010-04-21 19:46:23 +00003894

3917 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
3918
Victor Stinner0e59cc32010-04-16 23:49:32 +00003919- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

3931
Georg Brandl62069d32010-07-31 08:56:11 +00003932- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003933 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003934 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003935
Victor Stinner485fb562010-04-13 11:07:24 +00003936- Issue #8383: pickle and pickletools use surrogatepass error handler when
3937 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00003938 Python 2.x and 3.x.
Victor Stinner485fb562010-04-13 11:07:24 +00003939
R. David Murrayb2416e52010-04-12 16:58:02 +00003940- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003941 filename and date, conforming to the 'standards' they were originally designed
3942 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00003943
R. David Murrayef3d6bd2010-04-12 14:48:58 +00003944- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Georg Brandl62069d32010-07-31 08:56:11 +00003955 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3956 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00003957
Raymond Hettingerc50846a2010-04-05 18:56:31 +00003958- Add functools.total_ordering() and functools.cmp_to_key().
3959
Georg Brandl62069d32010-07-31 08:56:11 +00003960- Issue #8257: The Decimal construct now accepts a float instance directly,
3961 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003962
3963 >>> Decimal(1.1)
3964 Decimal('1.100000000000000088817841970012523233890533447265625')
3965

Georg Brandl62069d32010-07-31 08:56:11 +00003969- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3970 InvalidOperation instead of returning False. (Comparisons involving a quiet
3971 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3972 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003973
Georg Brandl62069d32010-07-31 08:56:11 +00003974- Issue #2531: Comparison operations between floats and Decimal instances now
3975 return a result based on the numeric values of the operands; previously they
3976 returned an arbitrary result based on the relative ordering of id(float) and
3977 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3978 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003979
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003980- Added a subtract() method to collections.Counter().
3981
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003982- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003983 argument `-` which tells it to read files to compile from stdin. Each line is
3984 read on demand and the named file is compiled immediately. (Original patch by
3985 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003986
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003987- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3988 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003989 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

3992 Fractions instance now raise TypeError instead of returning True/False. This
3993 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3994 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003996- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Georg Brandl62069d32010-07-31 08:56:11 +00004004 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4005 silenced.

Antoine Pitrou3c0fac22010-03-26 19:36:14 +00004010- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4011 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4012 reads and writes are always retried by OpenSSL itself.

4038 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4039 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004041- subprocess.Popen now has restore_signals and start_new_session features. The
4042 default of restore_signals=True is a new behavior compared to earlier Python
4043 versions. This means that signals such as SIGPIPE are not ignored by default
4044 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004321 default when instantiating a `threading.RLock` object. This makes recursive
4322 locks as fast as regular non-recursive locks (previously, they were slower by
4323 10x to 15x).

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004532- Issue #9959: Tweak formula used for computing math.log of an integer,
4533 making it marginally more accurate for exact powers of 2.

4536
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004537- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004538 compared to other unix systems. In particular, os.getgroups() does not reflect
4539 any changes made using os.setgroups() but basicly always returns the same
4540 information as the id command. os.getgroups() can now return more than 16
4541 groups on MacOSX.

Benjamin Petersonf751bc92010-07-02 13:46:42 +00004563- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
4564 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00004565
Georg Brandl62069d32010-07-31 08:56:11 +00004566- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4567 Prior to this change, timezone adjustment in utctimetuple() could produce
4568 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4569 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00004570
Georg Brandl62069d32010-07-31 08:56:11 +00004571- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4572 directive. When the ``%z`` directive is present in the format string, an
4573 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4574 ``datetime.timezone`` instance constructed from the parsed offset. If both
4575 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4576 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004577
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004578- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004579 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4580 ``datetime.timezone``, return fixed name and UTC offset from their
4581 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4582 returns ``None``. A class attribute, ``utc`` contains an instance
4583 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004599- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4600 with an improved 'binary-split' algorithm that uses fewer multiplications and
4601 allows many of the multiplications to be performed using plain C integer
4602 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4603 arguments.

4607
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004608- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4609 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004610 the result is now always correctly rounded, and is equivalent to ``td /
4611 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004619- Issue #8300: When passing a non-integer argument to struct.pack with any
4620 integer format code, struct.pack first attempts to convert the non-integer
4621 using its __index__ method. If that method is non-existent or raises
4622 TypeError it goes on to try the __int__ method, as described below.
4623

5002 errors property. Additionally, the errors and encoding properties of StringIO
5003 are always None now.
5004
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005005- Issue #6137: The pickle module now translates module names when loading
5006 or dumping pickles with a 2.x-compatible protocol, in order to make data
5007 sharing and migration easier. This behaviour can be disabled using the
5008 new `fix_imports` optional argument.

5061
Eric Smith41669ca2009-05-23 14:23:22 +00005062- Issue #6089: Fixed str.format with certain invalid field specifiers
5063 that would raise SystemError.
5064
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005065- Issue #5982: staticmethod and classmethod now expose the wrapped
5066 function with __func__.
5067
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005068- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005071- Issue #5829: complex("1e500") no longer raises OverflowError. This
5072 makes it consistent with float("1e500") and interpretation of real
5073 and imaginary literals.
5074
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005075- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005079- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5080 (1) inf and nan strings with trailing whitespace were incorrectly
5081 rejected; (2) parsing of strings representing infinities and nans
5082 was locale aware; and (3) the interpretation of fromhex('-nan')
5083 didn't match that of float('-nan').

5100
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005101- In unittest, using a skipping decorator on a class is now equivalent to
5102 skipping every test on the class. The ClassTestSuite class has been removed.
5103
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005104- Issue #6050: Don't fail extracting a directory from a zipfile if
5105 the directory already exists.
5106
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005107- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5108 than an int, which makes some operations possible under 64-bit Linux (e.g.
5109 DN_MULTISHOT with F_NOTIFY).
5110
Antoine Pitrou716c4442009-05-23 19:04:03 +00005111- Issue #5761: Add the name of the underlying file to the repr() of various
5112 IO objects.
5113
R. David Murraycaa27b72009-05-23 18:49:56 +00005114- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5115 by Musashi Tamura, tests by Marcin Bachry.
5116
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005117- Issue #1983: Fix functions taking or returning a process identifier to use
5118 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5119 a process identifier type wider than the standard C integer type.
5120
R. David Murray87e20742009-05-23 01:30:26 +00005121- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5132
Antoine Pitroue4501852009-05-14 18:55:55 +00005133- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5134 library. This means, for example, that opening an UTF-16 text file in
5135 append mode doesn't add a BOM at the end of the file if the file isn't
5136 empty.
5137
R. David Murray74b89242009-05-13 17:33:03 +00005138- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5139 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5140 corrects a pydoc regression.
5141
Georg Brandl5f90d792010-08-01 22:31:05 +00005142- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005143 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00005175- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005176 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005184*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005185
5186Core and Builtins
5187-----------------
5188
Mark Dickinson865e01a2009-05-07 16:37:01 +00005189- Issue #5914: Add new C API function PyOS_string_to_double, and
5190 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5191
Eric Smith741191f2009-05-06 13:08:15 +00005192- Issue #3382: float.__format__, complex.__format__, and %-formatting
5193 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5194 affects nan -> NAN and inf -> INF.
5195
Mark Hammond5a607a32009-05-06 08:04:54 +00005196- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5197 in all operations, including splitdrive, split, etc. splitunc() now issues
5198 a PendingDeprecation warning.
5199
Eric Smith63376222009-05-05 14:04:18 +00005200- Issue #5920: For float.__format__, change the behavior with the
5201 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5202 to be like 'g' but with at least one decimal point and with a
5203 default precision of 12. Previously, the behavior the same but with
5204 a default precision of 6. This more closely matches str(), and
5205 reduces surprises when adding alignment flags to the empty
5206 presentation type. This also affects the new complex.__format__ in
5207 the same way.
5208
Martin v. Löwis011e8422009-05-05 04:43:17 +00005209- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5210
R. David Murrayb18500d2009-05-04 22:59:07 +00005211- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5212 shadowed by classtype's, even if it was None. property now
5213 inserts the __doc__ into the subclass instance __dict__.
5214
Antoine Pitrou244651a2009-05-04 18:56:13 +00005215- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5216 sequences. Patch by Nick Barnes and Victor Stinner.
5217
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005218- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005219
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005220- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5221 received a new method, detach(). detach() disconnects the underlying stream
5222 from the buffer or text IO and returns it.
5223
Mark Dickinson33841c32009-05-01 15:37:04 +00005224- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5225 floats with absolute value over 1e50. Also remove length
5226 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5227 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005228
Eric Smith741191f2009-05-06 13:08:15 +00005229- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005230 format(complex(1, 2./3), '.5') now produces a sensible result.
5231
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005232- Issue #5864: Fix empty format code formatting for floats so that it
5233 never gives more than the requested number of significant digits.
5234
Eric Smith6dc46f52009-04-27 20:39:49 +00005235- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5236 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5237
Eric Smithcc32a112009-04-26 21:35:14 +00005238- Issue #5835: Deprecate PyOS_ascii_formatd.
5239
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005240- Issue #4971: Fix titlecase for characters that are their own
5241 titlecase, but not their own uppercase.
5242
Benjamin Peterson193152c2009-04-25 01:08:45 +00005243- Issue #5283: Setting __class__ in __del__ caused a segfault.
5244
Mark Dickinsonad476da2009-04-23 19:14:16 +00005245- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5246 z involves nans, infs or negative zeros.
5247
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005248- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005249
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005250- Issue #1869 (and many duplicates): make round(x, n) correctly
5251 rounded for a float x, by using the decimal <-> binary conversions
5252 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5253 consistently agrees with format(x, '.2f').
5254
Benjamin Petersonae937c02009-04-18 20:54:08 +00005255- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5256 some builtin types.
5257
Eric Smith0923d1d2009-04-16 20:16:10 +00005258- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5259
Eric Smith35e84722009-04-16 20:21:28 +00005260- Issue #5515: str.format() type 'n' combined with commas and leading
5261 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005262
5263- Implement PEP 378, Format Specifier for Thousands Separator, for
5264 floats.
5265
Mark Dickinson3370cce2009-04-17 22:40:53 +00005266- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005267 1e11, not 1e12. This avoids printing 13 significant digits in
5268 situations where only 12 of them are correct. Example problem
5269 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5270 long time.)
5271
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005272- Issue #1580: On most platforms, use a 'short' float repr: for a
5273 finite float x, repr(x) now outputs a string based on the shortest
5274 sequence of decimal digits that rounds to x. Previous behaviour was
5275 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005276 Another minor difference is that the new repr switches to
5277 exponential notation at 1e16 instead of the previous 1e17; this
5278 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005279
5280 There's a new sys attribute sys.float_repr_style, which takes
5281 the value 'short' to indicate that we're using short float repr,
5282 and 'legacy' if the short float repr isn't available for one
5283 reason or another.
5284
5285 The float repr change involves incorporating David Gay's 'perfect
5286 rounding' code into the Python core (it's in Python/dtoa.c). As a
5287 secondary consequence, all string-to-float and float-to-string
5288 conversions (including all float formatting operations) will be
5289 correctly rounded on these platforms.

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005292 this change does not apply.

5295
Georg Brandlabc38772009-04-12 15:51:51 +00005296- The string.maketrans() function is deprecated; there is a new static method
5297 maketrans() on the bytes and bytearray classes. This removes confusion about
5298 the types string.maketrans() is supposed to work with, and mirrors the
5299 methods available on the str class.

5580
Eric Smith5e5c0db2009-02-20 14:25:03 +00005581- Issue #5247: Improve error message when unknown format codes are
5582 used when using str.format() with str, int, and float arguments.
5583
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005584- Issue #5249: time.strftime returned malformed string when format string
5585 contained non ascii character on windows.
5586
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005587- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5588 source has already been decoded into str.
5589
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005590- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5591 rotating the object pointer by 4 bits to the right.
5592
Mark Dickinson87ec0852009-02-09 17:15:59 +00005593- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5594 it now forces its argument to double before testing for infinity.
5595
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005596- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5597 returns a non-number type.
5598
Benjamin Peterson87618552009-02-08 15:00:52 +00005599- Issue #5182: Removed memoryview.__str__.
5600
Mark Dickinsonc008a172009-02-01 13:59:22 +00005601- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5602 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005603 the type definition cmpfunc. The tp_compare slot has been renamed
5604 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005605
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005606- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005607 were suppressing all exceptions. These include list() and bytearray().
5608
Mark Dickinson1124e712009-01-28 21:25:58 +00005609- Issue #4707: round(x, n) now returns an integer if x is an integer.
5610 Previously it returned a float.
5611
Antoine Pitroub52ec782009-01-25 16:34:23 +00005612- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5613 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5614 evaluation loop is compiled with a new dispatch mechanism which gives
5615 speedups of up to 20%, depending on the system, on various benchmarks.
5616
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005617- Issue #4874: Most builtin decoders now reject unicode input.

5625 optional module state data.
5626
Mark Dickinson8055afd2009-01-17 10:04:45 +00005627- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005628 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005629
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005630- Issue #4935: The overflow checking code in the expandtabs() method common
5631 to str, bytes and bytearray could be optimized away by the compiler, letting
5632 the interpreter segfault instead of raising an error.
5633
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005634- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5635 __next__ method.
5636
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005637- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5638 function no longer attempt to call the __long__ slot to convert an object
5639 to an integer. Only the __int__ and __trunc__ slots are examined.
5640
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005641- Issue #4893: Use NT threading on CE.
5642

5644
Antoine Pitrouab868312009-01-10 15:40:25 +00005645- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5646 common cases are optimized thanks to a dedicated fast path and a moderate
5647 amount of loop unrolling.
5648
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005649- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5650 collecting the oldest generation) so that allocating lots of objects without
5651 destroying them does not show quadratic performance. Based on a proposal by
5652 Martin von Löwis at
5653 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5654
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005655- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005656 having been closed (for instance, a read() call could return some
5657 previously buffered data). Patch by Dmitry Vasiliev.
5658
Antoine Pitrou05608432009-01-09 18:53:14 +00005659- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5660 flag to work properly. Furthermore, when specifying -u, the text stdout
5661 and stderr streams have line-by-line buffering enabled (the default being
5662 to buffer arbitrary chunks of data).
5663
Raymond Hettinger35631532009-01-09 03:58:09 +00005664- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5665 instead of ints (reducing its size from 4 to 8 times thereby reducing
5666 Python's overall memory).
5667
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005668- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5669 an existing .py counterpart, override the co_filename attributes of all
5670 code objects if the original filename is obsolete (which can happen if the
5671 file has been renamed, moved, or if it is accessed through different paths).
5672 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5673
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005674- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5675 one byte. Also fixes the meaning of len() so that it returns the number of
5676 items, rather than the size in bytes.
5677
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005678- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5679
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005680- Issue #4747: When the terminal does not use utf-8, executing a script with
5681 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5682
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005683- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5684 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005685
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005686- Issue #3680: Reference cycles created through a dict, set or deque iterator
5687 did not get collected.
5688
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005689- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5690 where the tp_hash and tp_dict slots are both NULL.
5691
Georg Brandlccc47b62008-12-28 11:44:14 +00005692- Issue #4759: None is now allowed as the first argument of
5693 bytearray.translate(). It was always allowed for bytes.translate().
5694
Skip Montanaro80072cb2008-12-23 03:51:14 +00005695- Added test case to ensure attempts to read from a file opened for writing
5696 fail.
5697
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005698- Issue #3106: Speedup some comparisons (str/str and int/int).

5701 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5702
Antoine Pitrou621601a2008-12-17 23:18:19 +00005703- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5704 print elapsed times, not only when some objects are uncollectable /
5705 unreachable. Original patch by Neil Schemenauer.
5706
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005707- Issue #3439: Add a bit_length method to int.
5708
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005709- Issue #2173: When getting device encoding, check that return value of
5710 nl_langinfo is not the empty string. This was causing silent build
5711 failures on OS X.
5712
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005713- Issue #4597: Fixed several opcodes that weren't always propagating
5714 exceptions.
5715
5716- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005717 context manager returns a value that cannot be converted to a bool.
5718
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005719- Issue #4445: Replace "sizeof(PyBytesObject)" with
5720 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5721 bytes instances. On a typical machine this saves 3 bytes of memory
5722 (on average) per allocation of a bytes instance.
5723
Christian Heimesa872de52008-12-05 08:26:55 +00005724- Issue #4533: File read operation was dreadfully slow due to a slowly
5725 growing read buffer. Fixed by using the same growth rate algorithm as
5726 Python 2.x.
5727
Antoine Pitrou5504e892008-12-06 21:27:53 +00005728- Issue #4509: Various issues surrounding resize of bytearray objects to
5729 which there are buffer exports (e.g. memoryview instances).
5730
Georg Brandlf9734072008-12-07 15:30:06 +00005731- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5732 method on file objects with closefd=False. The file descriptor is still
5733 kept open but the file object behaves like a closed file. The ``FileIO``
5734 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005735
Antoine Pitroubc420402008-12-07 20:14:49 +00005736- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5737 larger than 1.

5742
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005743- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5744 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5745 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5746 of using the replace error handler in PyUnicode_DecodeUTF8().
