629 interpreter process. This could cause failures in non-Distutils subprocesses
630 and was unreliable since tests or user programs could modify the interpreter
631 environment after Distutils set it. Instead, have Distutils set the the
632 deployment target only in the environment of each build subprocess. It is
633 still possible to globally override the default by setting
634 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
635 greater or equal to the default value, the value with which the interpreter
636 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002134 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2477-----------------
2478
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002479- Issue #10068: Global objects which have reference cycles with their module's
2480 dict are now cleared again. This causes issue #7140 to appear again.
2481
Victor Stinner257d38f2010-10-09 10:12:11 +00002482- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002483 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002484
Georg Brandl27a28582010-10-10 09:49:21 +00002485- ast.literal_eval() can now handle negative numbers. It is also a little more
2486 liberal in what it accepts without compromising the safety of the evaluation.
2487 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002488
Benjamin Peterson970d1882010-10-02 17:55:47 +00002489- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2490 result metaclasses can now be ABCs (see #9533).
2491
Victor Stinneraef57e32010-10-02 11:50:49 +00002492- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2493
Victor Stinner5593d8a2010-10-02 11:11:27 +00002494- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002495 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2496 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +00002501- Issue #9979: Create function PyUnicode_AsWideCharString().
2502
Brett Cannon5305a992010-09-27 21:08:38 +00002503- Issue #7397: Mention that importlib.import_module() is probably what someone
2504 really wants to be using in __import__'s docstring.
2505
Georg Brandl27a28582010-10-10 09:49:21 +00002506- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2507 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002508
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002509- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002510 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002511
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002512- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2513
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002514- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2515 threads are still running. Instead, reinitialize the GIL on a second call to
2516 Py_Initialize().
2517
Georg Brandl27a28582010-10-10 09:49:21 +00002518- All SyntaxErrors now have a column offset and therefore a caret when the error
2519 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002520
Brett Cannonbc2eff32010-09-19 21:39:02 +00002521- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2522 module that was imported, but instead gets the module from sys.modules.
2523
Nick Coghlan37ee8502010-12-03 14:26:13 +00002524- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002525 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002526
Georg Brandl27a28582010-10-10 09:49:21 +00002527- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2528 with a non-empty format string. This is an effort to future-proof user
2529 code. If a derived class does not currently implement __format__ but later
2530 adds its own __format__, it would most likely break user code that had
2531 supplied a format string. This will be changed to a DeprecationWaring in
2532 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002533
Antoine Pitrou1df15362010-09-13 14:16:46 +00002534- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2535 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2536 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2537
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002538- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2539 functions from the libc caused the methods .upper() and lower() to become
2540 locale aware and created subtly wrong results.
2541
Georg Brandl27a28582010-10-10 09:49:21 +00002542- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2543 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002544
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002545- Issue #4617: Previously it was illegal to delete a name from the local
2546 namespace if it occurs as a free variable in a nested block. This limitation
2547 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2548
Georg Brandl27a28582010-10-10 09:49:21 +00002549- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2550 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2551 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2552 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002553
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002554- Issue #9757: memoryview objects get a release() method to release the
2555 underlying buffer (previously this was only done when deallocating the
2556 memoryview), and gain support for the context management protocol.
2557
Antoine Pitrou079ce542010-09-08 12:37:10 +00002558- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2559 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002575- Issue #4661: email can now parse bytes input and generate either converted
2576 7bit output or bytes output. Email version bumped to 5.1.0.
2577
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002578- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2579 verification for higher-level protocols.
2580
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002581- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2582 after the file is closed. Patch by Jeffrey Finkelstein.
2583
Éric Araujo6108bf52010-10-04 23:52:37 +00002584- Issue #9042: Fix interaction of custom translation classes and caching in
2585 gettext.
2586
Éric Araujoef777bd2010-10-05 00:04:20 +00002587- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002588 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002589 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002590 replacement for old handle_accept() and avoids the user to call accept()
2591 directly.
2592
Lars Gustäbel331b8002010-10-04 15:18:47 +00002593- Issue #9065: tarfile no longer uses "root" as the default for the uname and

R. David Murray5397e862010-10-02 15:58:26 +00002599- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2600 characters that appear inside quoted strings in email addresses.

Georg Brandl27a28582010-10-10 09:49:21 +00002602- Issue #10004: quoprimime no longer generates a traceback when confronted with

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002612- Issue #9962: GzipFile now has the peek() method.
2613
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002614- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002615 retry the select() loop instead of bailing out. This is because select() can
2616 incorrectly report a socket as ready for reading (for example, if it received
2617 some data with an invalid checksum).

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002691- Issue #9837: The read() method of ZipExtFile objects (as returned by
2692 ZipFile.open()) could return more bytes than requested.
2693
Georg Brandl27a28582010-10-10 09:49:21 +00002694- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2695 d['x'] = d.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002697- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002698 it possible for the user to create self-referencing ordered dictionaries which
2699 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002700 approach of using weakref proxies so that reference cycles never get created
2701 in the first place.
2702
Victor Stinnercb043522010-09-10 23:49:04 +00002703- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2704 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002705 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002706
Georg Brandl27a28582010-10-10 09:49:21 +00002707- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2708 environment variable to set the filesystem encoding at Python startup.
2709 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2710 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002711
Georg Brandl27a28582010-10-10 09:49:21 +00002712- Issue #9410: Various optimizations to the pickle module, leading to speedups
2713 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2714 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002715
Georg Brandl27a28582010-10-10 09:49:21 +00002716- The pprint module now supports printing OrderedDicts in their given order
2717 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002718
Vinay Sajip121a1c42010-09-08 10:46:15 +00002719- Logging: Added QueueHandler class to facilitate logging usage with
2720 multiprocessing.
2721
Georg Brandl27a28582010-10-10 09:49:21 +00002722- Issue #9707: Rewritten reference implementation of threading.local which is
2723 friendlier towards reference cycles. This change is not normally visible
2724 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002725
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002726- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2727 still return the id of the parent process after it has exited. This process
2728 id may even have been reused by another unrelated process.
2729
Georg Brandl27a28582010-10-10 09:49:21 +00002730- Issue #9792: In case of connection failure, socket.create_connection() would
2731 swallow the exception and raise a new one, making it impossible to fetch the
2732 original errno, or to filter timeout errors. Now the original error is
2733 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002735- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2736 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2737 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002739- Updates to the random module:
2740
Georg Brandl27a28582010-10-10 09:49:21 +00002741 * Document which parts of the module are guaranteed to stay the same across
2742 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002743
Georg Brandl27a28582010-10-10 09:49:21 +00002744 * Update the seed() method to use all of the bits in a string instead of just
2745 the hash value. This makes better use of the seed value and assures the
2746 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002747
Georg Brandl27a28582010-10-10 09:49:21 +00002748 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2749 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2750 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002751
2752 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002757- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2758 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2759 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002760
Georg Brandl27a28582010-10-10 09:49:21 +00002761- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2762 their contents without duplicating them. The view is both readable and
2763 writable.

2766
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002767- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002768 unsupported operation is attempted (for example, writing to a file open only
2769 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002771- hashlib has two new constant attributes: algorithms_guaranteed and
2772 algorithms_avaiable that respectively list the names of hash algorithms
2773 guaranteed to exist in all Python implementations and the names of hash
2774 algorithms available in the current process.
2775
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002776- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002866- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2867 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2868 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00002869
Brett Cannonef0e6c32010-09-04 18:24:04 +00002870- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Georg Brandl649971e2010-09-05 17:06:50 +00002879- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2880 now removed, since their effect was inexistent in 3.x (the default encoding is
2881 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002882
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002883- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
2884 properly. Patch by Stefan Behnel.
2885
Georg Brandl649971e2010-09-05 17:06:50 +00002886- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2887 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002888

2903 return characters from the full Unicode range, even on narrow unicode builds
2904 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2905 in Python is that unicodedata.numeric() now returns the correct value for
2906 large code points, and repr() may consider more characters as printable.
2907
Victor Stinner6c00c142010-08-17 23:37:11 +00002908- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

2910 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2911 function.
2912
Victor Stinner6961bd62010-08-17 22:26:51 +00002913- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

2916
Georg Brandl649971e2010-09-05 17:06:50 +00002917- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2918 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002919

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002924- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002925 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2926 objects are output as-is.

2930 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002931
Georg Brandl649971e2010-09-05 17:06:50 +00002932- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2933 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002934
Georg Brandl649971e2010-09-05 17:06:50 +00002935- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an

Ezio Melotti57221d02010-07-01 07:32:02 +00003286- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003287 start byte and the continuation byte(s) are now considered invalid, instead of
3288 the number of bytes specified by the start byte. E.g.:
3289 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3290 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3291 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3292 returned a single u'\ufffd'.

3321
Georg Brandl62069d32010-07-31 08:56:11 +00003322- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003323 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3324 location of the raised exception.
3325
Victor Stinner313a1202010-06-11 23:56:51 +00003326- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode

Georg Brandl62069d32010-07-31 08:56:11 +00003335- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3336 TypeError instead of giving a DeprecationWarning when a float is parsed using
3337 the 'L' code (for long long). (All other integer codes already raise
3338 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003339
Victor Stinner600d3be2010-06-10 12:00:55 +00003340- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3341 enable shortcuts for upper case encoding name. Add also a shortcut for
3342 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3343
Georg Brandl62069d32010-07-31 08:56:11 +00003344- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3345 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003346
3347- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003348 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003349 like bytearray.
3350
Georg Brandl62069d32010-07-31 08:56:11 +00003351- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003352 used anymore and it was never documented.
3353
Georg Brandl62069d32010-07-31 08:56:11 +00003354- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003358
Georg Brandl62069d32010-07-31 08:56:11 +00003359- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3360 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3361 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3362 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003363
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003364- Issue #8748: Fix two issues with comparisons between complex and integer
3365 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003366 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3367 (2) The comparison raised an OverflowError for large integers, leading to
3368 unpredictable exceptions when combining integers and complex objects in sets
3369 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003370

3373
Victor Stinner9ca9c252010-05-19 16:53:30 +00003374- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003375 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003376 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.

Georg Brandl62069d32010-07-31 08:56:11 +00003378- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3379 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003380
Victor Stinnerae6265f2010-05-15 16:27:27 +00003381- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3382 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003383 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003384 back to UTF-8.

3699 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3700 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003701 to match the behaviour of the other integer format codes.

3730 gives improved memory leak detection when running under Valgrind, while taking
3731 advantage of pymalloc at other times.

3807 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003808 applications that use a lot of regular expressions and limits the impact of
3809 the performance hit anytime the cache is exceeded.

3823 defined in datetime with fast C impementation. Python implementation is based
3824 on the original python prototype for the datetime module by Tim Peters with
3825 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004101- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4102 the method could block indefinitely if called just before the event loop

Georg Brandl62069d32010-07-31 08:56:11 +00004106- Issue #8524: When creating an SSL socket, the timeout value of the original
4107 socket wasn't retained (instead, a socket with a positive timeout would be
4108 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004109
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004110- Issue #5103: SSL handshake would ignore the socket timeout and block
4111 indefinitely if the other end didn't respond.
4112
Georg Brandl62069d32010-07-31 08:56:11 +00004113- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4114 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00004181- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004182 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004183 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00004189- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004190 filename and date, conforming to the 'standards' they were originally designed

Antoine Pitrou04f6a322010-04-05 21:40:07 +00004203- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00004204 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004207- Add functools.total_ordering() and functools.cmp_to_key().
4208
Georg Brandl62069d32010-07-31 08:56:11 +00004209- Issue #8257: The Decimal construct now accepts a float instance directly,
4210 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004211
4212 >>> Decimal(1.1)
4213 Decimal('1.100000000000000088817841970012523233890533447265625')
4214
Georg Brandl62069d32010-07-31 08:56:11 +00004215- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4216 directly.

Georg Brandl62069d32010-07-31 08:56:11 +00004218- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4219 InvalidOperation instead of returning False. (Comparisons involving a quiet
4220 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4221 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004222
Georg Brandl62069d32010-07-31 08:56:11 +00004223- Issue #2531: Comparison operations between floats and Decimal instances now
4224 return a result based on the numeric values of the operands; previously they
4225 returned an arbitrary result based on the relative ordering of id(float) and
4226 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4227 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004228
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004229- Added a subtract() method to collections.Counter().
4230
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004231- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004232 argument `-` which tells it to read files to compile from stdin. Each line is
4233 read on demand and the named file is compiled immediately. (Original patch by
4234 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004236- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4237 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004238 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004240- Comparisons using one of <, <=, >, >= between a complex instance and a
4241 Fractions instance now raise TypeError instead of returning True/False. This
4242 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4243 <=> complex, and complex <=> complex comparisons.

4251
Antoine Pitrou910bd512010-03-22 20:11:09 +00004252- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004253 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004286- The internals of the subprocess module on POSIX systems have been replaced by
4287 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4288 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004289
Georg Brandl62069d32010-07-31 08:56:11 +00004290- subprocess.Popen now has restore_signals and start_new_session features. The
4291 default of restore_signals=True is a new behavior compared to earlier Python
4292 versions. This means that signals such as SIGPIPE are not ignored by default
4293 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004548- Issue #6816: runpy now provides a run_path function that allows Python code to
4549 execute file paths that refer to source or compiled Python files as well as
4550 zipfiles, directories and other valid sys.path entries that contain a
4551 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00004552 support the same flexibility as the CPython command line itself.

Antoine Pitrou434736a2009-11-10 18:46:01 +00004569- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004570 default when instantiating a `threading.RLock` object. This makes recursive
4571 locks as fast as regular non-recursive locks (previously, they were slower by

4592 from stdin so that existing input does not confuse it and lead to incorrect
4593 entry or an IOError. It also properly flushes it afterwards to avoid the
4594 terminal echoing the input afterwards on OSes such as Solaris.

Georg Brandl62069d32010-07-31 08:56:11 +00004787 compared to other unix systems. In particular, os.getgroups() does not reflect
4788 any changes made using os.setgroups() but basicly always returns the same
4789 information as the id command. os.getgroups() can now return more than 16
4790 groups on MacOSX.

4816 Prior to this change, timezone adjustment in utctimetuple() could produce
4817 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00004820- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4821 directive. When the ``%z`` directive is present in the format string, an
4822 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4823 ``datetime.timezone`` instance constructed from the parsed offset. If both
4824 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4825 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00004828 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4829 ``datetime.timezone``, return fixed name and UTC offset from their
4830 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4831 returns ``None``. A class attribute, ``utc`` contains an instance
4832 representing the UTC timezone. Original patch by Rafe Kaplan.

4850 allows many of the multiplications to be performed using plain C integer
4851 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Georg Brandl62069d32010-07-31 08:56:11 +00004859 the result is now always correctly rounded, and is equivalent to ``td /

5146 threads could return successfully while some Thread objects were still
5147 referenced. This also introduces a new private function:

R. David Murray0bc11ae2009-10-18 22:18:17 +00005156- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005157 runtest_inner in regrtest, with warnings if the called test modifies them, and

5310
Eric Smith41669ca2009-05-23 14:23:22 +00005311- Issue #6089: Fixed str.format with certain invalid field specifiers
5312 that would raise SystemError.
5313
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005314- Issue #5982: staticmethod and classmethod now expose the wrapped
5315 function with __func__.
5316
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005317- Added support for multiple context managers in the same with-statement.
5318 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005320- Issue #5829: complex("1e500") no longer raises OverflowError. This
5321 makes it consistent with float("1e500") and interpretation of real
5322 and imaginary literals.
5323
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005324- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

5327
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005328- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5329 (1) inf and nan strings with trailing whitespace were incorrectly
5330 rejected; (2) parsing of strings representing infinities and nans
5331 was locale aware; and (3) the interpretation of fromhex('-nan')
5332 didn't match that of float('-nan').

5348 names: cls, self, tuple, itemgetter, and property.
5349
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005350- In unittest, using a skipping decorator on a class is now equivalent to
5351 skipping every test on the class. The ClassTestSuite class has been removed.
5352
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005353- Issue #6050: Don't fail extracting a directory from a zipfile if
5354 the directory already exists.
5355
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005356- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5357 than an int, which makes some operations possible under 64-bit Linux (e.g.
5358 DN_MULTISHOT with F_NOTIFY).
5359
Antoine Pitrou716c4442009-05-23 19:04:03 +00005360- Issue #5761: Add the name of the underlying file to the repr() of various
5361 IO objects.
5362
R. David Murraycaa27b72009-05-23 18:49:56 +00005363- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5364 by Musashi Tamura, tests by Marcin Bachry.
5365
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005366- Issue #1983: Fix functions taking or returning a process identifier to use
5367 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5368 a process identifier type wider than the standard C integer type.
5369
R. David Murray87e20742009-05-23 01:30:26 +00005370- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5381
Antoine Pitroue4501852009-05-14 18:55:55 +00005382- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5383 library. This means, for example, that opening an UTF-16 text file in
5384 append mode doesn't add a BOM at the end of the file if the file isn't
5385 empty.
5386
R. David Murray74b89242009-05-13 17:33:03 +00005387- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5388 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5389 corrects a pydoc regression.
5390
Georg Brandl5f90d792010-08-01 22:31:05 +00005391- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005392 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005433*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005434
5435Core and Builtins
5436-----------------
5437
Mark Dickinson865e01a2009-05-07 16:37:01 +00005438- Issue #5914: Add new C API function PyOS_string_to_double, and
5439 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5440
Eric Smith741191f2009-05-06 13:08:15 +00005441- Issue #3382: float.__format__, complex.__format__, and %-formatting
5442 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5443 affects nan -> NAN and inf -> INF.
5444
Mark Hammond5a607a32009-05-06 08:04:54 +00005445- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5446 in all operations, including splitdrive, split, etc. splitunc() now issues
5447 a PendingDeprecation warning.
5448
Eric Smith63376222009-05-05 14:04:18 +00005449- Issue #5920: For float.__format__, change the behavior with the
5450 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5451 to be like 'g' but with at least one decimal point and with a
5452 default precision of 12. Previously, the behavior the same but with
5453 a default precision of 6. This more closely matches str(), and
5454 reduces surprises when adding alignment flags to the empty
5455 presentation type. This also affects the new complex.__format__ in
5456 the same way.
5457
Martin v. Löwis011e8422009-05-05 04:43:17 +00005458- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5459
R. David Murrayb18500d2009-05-04 22:59:07 +00005460- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5461 shadowed by classtype's, even if it was None. property now
5462 inserts the __doc__ into the subclass instance __dict__.
5463
Antoine Pitrou244651a2009-05-04 18:56:13 +00005464- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5465 sequences. Patch by Nick Barnes and Victor Stinner.
5466
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005467- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005468
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005469- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5470 received a new method, detach(). detach() disconnects the underlying stream
5471 from the buffer or text IO and returns it.
5472
Mark Dickinson33841c32009-05-01 15:37:04 +00005473- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5474 floats with absolute value over 1e50. Also remove length
5475 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5476 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005477
Eric Smith741191f2009-05-06 13:08:15 +00005478- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005479 format(complex(1, 2./3), '.5') now produces a sensible result.
5480
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005481- Issue #5864: Fix empty format code formatting for floats so that it
5482 never gives more than the requested number of significant digits.
5483
Eric Smith6dc46f52009-04-27 20:39:49 +00005484- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5485 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5486
Eric Smithcc32a112009-04-26 21:35:14 +00005487- Issue #5835: Deprecate PyOS_ascii_formatd.
5488
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005489- Issue #4971: Fix titlecase for characters that are their own
5490 titlecase, but not their own uppercase.
5491
Benjamin Peterson193152c2009-04-25 01:08:45 +00005492- Issue #5283: Setting __class__ in __del__ caused a segfault.
5493
Mark Dickinsonad476da2009-04-23 19:14:16 +00005494- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5495 z involves nans, infs or negative zeros.
5496
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005497- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005498
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005499- Issue #1869 (and many duplicates): make round(x, n) correctly
5500 rounded for a float x, by using the decimal <-> binary conversions
5501 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5502 consistently agrees with format(x, '.2f').
5503
Benjamin Petersonae937c02009-04-18 20:54:08 +00005504- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5505 some builtin types.
5506
Eric Smith0923d1d2009-04-16 20:16:10 +00005507- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5508
Eric Smith35e84722009-04-16 20:21:28 +00005509- Issue #5515: str.format() type 'n' combined with commas and leading
5510 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005511
5512- Implement PEP 378, Format Specifier for Thousands Separator, for
5513 floats.
5514
Mark Dickinson3370cce2009-04-17 22:40:53 +00005515- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005516 1e11, not 1e12. This avoids printing 13 significant digits in
5517 situations where only 12 of them are correct. Example problem
5518 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5519 long time.)
5520
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005521- Issue #1580: On most platforms, use a 'short' float repr: for a
5522 finite float x, repr(x) now outputs a string based on the shortest
5523 sequence of decimal digits that rounds to x. Previous behaviour was
5524 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005525 Another minor difference is that the new repr switches to
5526 exponential notation at 1e16 instead of the previous 1e17; this
5527 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005528
5529 There's a new sys attribute sys.float_repr_style, which takes
5530 the value 'short' to indicate that we're using short float repr,
5531 and 'legacy' if the short float repr isn't available for one
5532 reason or another.
5533
5534 The float repr change involves incorporating David Gay's 'perfect
5535 rounding' code into the Python core (it's in Python/dtoa.c). As a
5536 secondary consequence, all string-to-float and float-to-string
5537 conversions (including all float formatting operations) will be
5538 correctly rounded on these platforms.
5539
Georg Brandl5f90d792010-08-01 22:31:05 +00005540 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005541 this change does not apply.
5542
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005543- Issue #5759: float() didn't call __float__ on str subclasses.
5544
Georg Brandlabc38772009-04-12 15:51:51 +00005545- The string.maketrans() function is deprecated; there is a new static method
5546 maketrans() on the bytes and bytearray classes. This removes confusion about
5547 the types string.maketrans() is supposed to work with, and mirrors the
5548 methods available on the str class.
5549
R. David Murraydc6da8a2009-04-09 22:16:43 +00005550- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5551 its clarity and its speed.
5552
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005553- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005554 to avoid compiler warnings.
5555
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005556- Issue #3739: The unicode-internal encoder now reports the number of characters
5557 consumed like any other encoder (instead of the number of bytes).

Mark Dickinson1124e712009-01-28 21:25:58 +00005858- Issue #4707: round(x, n) now returns an integer if x is an integer.
5859 Previously it returned a float.
5860
Antoine Pitroub52ec782009-01-25 16:34:23 +00005861- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5862 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5863 evaluation loop is compiled with a new dispatch mechanism which gives
5864 speedups of up to 20%, depending on the system, on various benchmarks.
5865
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005866- Issue #4874: Most builtin decoders now reject unicode input.

5874 optional module state data.
5875
Mark Dickinson8055afd2009-01-17 10:04:45 +00005876- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005877 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005878
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005879- Issue #4935: The overflow checking code in the expandtabs() method common
5880 to str, bytes and bytearray could be optimized away by the compiler, letting
5881 the interpreter segfault instead of raising an error.
5882
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005883- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5884 __next__ method.
5885
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005886- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5887 function no longer attempt to call the __long__ slot to convert an object
5888 to an integer. Only the __int__ and __trunc__ slots are examined.

5893
Antoine Pitrouab868312009-01-10 15:40:25 +00005894- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5895 common cases are optimized thanks to a dedicated fast path and a moderate
5896 amount of loop unrolling.
5897
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005898- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5899 collecting the oldest generation) so that allocating lots of objects without
5900 destroying them does not show quadratic performance. Based on a proposal by
5901 Martin von Löwis at
5902 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5903
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005904- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005905 having been closed (for instance, a read() call could return some
5906 previously buffered data). Patch by Dmitry Vasiliev.
5907
Antoine Pitrou05608432009-01-09 18:53:14 +00005908- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5909 flag to work properly. Furthermore, when specifying -u, the text stdout
5910 and stderr streams have line-by-line buffering enabled (the default being
5911 to buffer arbitrary chunks of data).
5912
Raymond Hettinger35631532009-01-09 03:58:09 +00005913- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5914 instead of ints (reducing its size from 4 to 8 times thereby reducing
5915 Python's overall memory).
5916
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005917- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5918 an existing .py counterpart, override the co_filename attributes of all
5919 code objects if the original filename is obsolete (which can happen if the
5920 file has been renamed, moved, or if it is accessed through different paths).
5921 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5922
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005923- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5924 one byte. Also fixes the meaning of len() so that it returns the number of
5925 items, rather than the size in bytes.
5926
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005927- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5928
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005929- Issue #4747: When the terminal does not use utf-8, executing a script with
5930 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5931
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005932- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5936 did not get collected.
5937
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005938- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5939 where the tp_hash and tp_dict slots are both NULL.
5940
Georg Brandlccc47b62008-12-28 11:44:14 +00005941- Issue #4759: None is now allowed as the first argument of
5942 bytearray.translate(). It was always allowed for bytes.translate().
5943
Skip Montanaro80072cb2008-12-23 03:51:14 +00005944- Added test case to ensure attempts to read from a file opened for writing
5945 fail.
5946
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005947- Issue #3106: Speedup some comparisons (str/str and int/int).

5951
Antoine Pitrou621601a2008-12-17 23:18:19 +00005952- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5957
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005958- Issue #2173: When getting device encoding, check that return value of
5959 nl_langinfo is not the empty string. This was causing silent build
5960 failures on OS X.
5961
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005962- Issue #4597: Fixed several opcodes that weren't always propagating
5963 exceptions.
5964
5965- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005966 context manager returns a value that cannot be converted to a bool.
5967
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005968- Issue #4445: Replace "sizeof(PyBytesObject)" with
5969 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5970 bytes instances. On a typical machine this saves 3 bytes of memory
5971 (on average) per allocation of a bytes instance.
5972
Christian Heimesa872de52008-12-05 08:26:55 +00005973- Issue #4533: File read operation was dreadfully slow due to a slowly
5974 growing read buffer. Fixed by using the same growth rate algorithm as
5975 Python 2.x.
5976
Antoine Pitrou5504e892008-12-06 21:27:53 +00005977- Issue #4509: Various issues surrounding resize of bytearray objects to
5978 which there are buffer exports (e.g. memoryview instances).
5979
Georg Brandlf9734072008-12-07 15:30:06 +00005980- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5981 method on file objects with closefd=False. The file descriptor is still
5982 kept open but the file object behaves like a closed file. The ``FileIO``
5983 object also got a new readonly attribute ``closefd``.

5991
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005992- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5993 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5994 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5995 of using the replace error handler in PyUnicode_DecodeUTF8().

6316 do an explicit seek to the end of file (so that e.g. tell() returns the
