Antoine Pitrou84f1b172011-07-12 21:57:15 +020013- Issue #12149: Update the method cache after a type's dictionnary gets
14 cleared by the garbage collector. This fixes a segfault when an instance
15 and its type get caught in a reference cycle, and the instance's
16 deallocator calls one of the methods on the type (e.g. when subclassing
17 IOBase). Diagnosis and patch by Davide Rizzo.

296 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
297 interpreter process. This could cause failures in non-Distutils subprocesses
298 and was unreliable since tests or user programs could modify the interpreter
299 environment after Distutils set it. Instead, have Distutils set the the
300 deployment target only in the environment of each build subprocess. It is
301 still possible to globally override the default by setting
302 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
303 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700304 was built. Also, implement the same handling in packaging.

Georg Brandl255abdd2011-01-16 14:17:26 +00001439 continuation line in the formatted value has no leading white space and looks
1440 like a header. Since Generator uses Header to format all headers, this check
1441 is made for all headers in any serialized message at serialization time. This
1442 provides protection against header injection attacks.

1456 folding whitespace. It now uses the continuation_ws, as it does for
1457 continuation lines that it creates itself.

1462 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1463 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1464 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002097 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002098 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2442
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002443- Issue #10068: Global objects which have reference cycles with their module's
2444 dict are now cleared again. This causes issue #7140 to appear again.
2445
Victor Stinner257d38f2010-10-09 10:12:11 +00002446- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002447 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002448
Georg Brandl27a28582010-10-10 09:49:21 +00002449- ast.literal_eval() can now handle negative numbers. It is also a little more
2450 liberal in what it accepts without compromising the safety of the evaluation.
2451 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002452
Benjamin Peterson970d1882010-10-02 17:55:47 +00002453- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2454 result metaclasses can now be ABCs (see #9533).
2455
Victor Stinneraef57e32010-10-02 11:50:49 +00002456- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2457
Victor Stinner5593d8a2010-10-02 11:11:27 +00002458- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002459 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2460 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +00002465- Issue #9979: Create function PyUnicode_AsWideCharString().
2466
Brett Cannon5305a992010-09-27 21:08:38 +00002467- Issue #7397: Mention that importlib.import_module() is probably what someone
2468 really wants to be using in __import__'s docstring.
2469
Georg Brandl27a28582010-10-10 09:49:21 +00002470- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2471 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002472
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002473- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002474 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002475
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002476- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2477
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002478- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2479 threads are still running. Instead, reinitialize the GIL on a second call to
2480 Py_Initialize().
2481
Georg Brandl27a28582010-10-10 09:49:21 +00002482- All SyntaxErrors now have a column offset and therefore a caret when the error
2483 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002484
Brett Cannonbc2eff32010-09-19 21:39:02 +00002485- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2486 module that was imported, but instead gets the module from sys.modules.
2487
Nick Coghlan37ee8502010-12-03 14:26:13 +00002488- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002489 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002490
Georg Brandl27a28582010-10-10 09:49:21 +00002491- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2492 with a non-empty format string. This is an effort to future-proof user
2493 code. If a derived class does not currently implement __format__ but later
2494 adds its own __format__, it would most likely break user code that had
2495 supplied a format string. This will be changed to a DeprecationWaring in
2496 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002497
Antoine Pitrou1df15362010-09-13 14:16:46 +00002498- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2499 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2500 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2501
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002502- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2503 functions from the libc caused the methods .upper() and lower() to become
2504 locale aware and created subtly wrong results.
2505
Georg Brandl27a28582010-10-10 09:49:21 +00002506- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2507 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002508
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002509- Issue #4617: Previously it was illegal to delete a name from the local
2510 namespace if it occurs as a free variable in a nested block. This limitation
2511 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2512
Georg Brandl27a28582010-10-10 09:49:21 +00002513- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2514 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2515 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2516 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002517
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002518- Issue #9757: memoryview objects get a release() method to release the
2519 underlying buffer (previously this was only done when deallocating the
2520 memoryview), and gain support for the context management protocol.
2521
Antoine Pitrou079ce542010-09-08 12:37:10 +00002522- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2523 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002539- Issue #4661: email can now parse bytes input and generate either converted
2540 7bit output or bytes output. Email version bumped to 5.1.0.
2541
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002542- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2544
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002545- Issue #9759: GzipFile now raises ValueError when an operation is attempted

2547
Éric Araujo6108bf52010-10-04 23:52:37 +00002548- Issue #9042: Fix interaction of custom translation classes and caching in
2549 gettext.
2550
Éric Araujoef777bd2010-10-05 00:04:20 +00002551- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002552 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002553 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002554 replacement for old handle_accept() and avoids the user to call accept()
2555 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002557- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002578- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002579 retry the select() loop instead of bailing out. This is because select() can
2580 incorrectly report a socket as ready for reading (for example, if it received
2581 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002658- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2659 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002660
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002661- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002662 it possible for the user to create self-referencing ordered dictionaries which
2663 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002664 approach of using weakref proxies so that reference cycles never get created
2665 in the first place.
2666
Victor Stinnercb043522010-09-10 23:49:04 +00002667- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2668 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002669 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002670
Georg Brandl27a28582010-10-10 09:49:21 +00002671- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2672 environment variable to set the filesystem encoding at Python startup.
2673 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2674 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002675
Georg Brandl27a28582010-10-10 09:49:21 +00002676- Issue #9410: Various optimizations to the pickle module, leading to speedups
2677 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2678 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002679
Georg Brandl27a28582010-10-10 09:49:21 +00002680- The pprint module now supports printing OrderedDicts in their given order
2681 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002682
Vinay Sajip121a1c42010-09-08 10:46:15 +00002683- Logging: Added QueueHandler class to facilitate logging usage with
2684 multiprocessing.
2685
Georg Brandl27a28582010-10-10 09:49:21 +00002686- Issue #9707: Rewritten reference implementation of threading.local which is
2687 friendlier towards reference cycles. This change is not normally visible
2688 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002689
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002690- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2691 still return the id of the parent process after it has exited. This process
2692 id may even have been reused by another unrelated process.
2693
Georg Brandl27a28582010-10-10 09:49:21 +00002694- Issue #9792: In case of connection failure, socket.create_connection() would
2695 swallow the exception and raise a new one, making it impossible to fetch the
2696 original errno, or to filter timeout errors. Now the original error is
2697 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002699- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2700 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2701 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002702
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002703- Updates to the random module:
2704
Georg Brandl27a28582010-10-10 09:49:21 +00002705 * Document which parts of the module are guaranteed to stay the same across
2706 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002707
Georg Brandl27a28582010-10-10 09:49:21 +00002708 * Update the seed() method to use all of the bits in a string instead of just
2709 the hash value. This makes better use of the seed value and assures the
2710 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002711
Georg Brandl27a28582010-10-10 09:49:21 +00002712 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2713 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2714 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002715
2716 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002721- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2722 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2723 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002724
Georg Brandl27a28582010-10-10 09:49:21 +00002725- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2726 their contents without duplicating them. The view is both readable and
2727 writable.

2730
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002731- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002732 unsupported operation is attempted (for example, writing to a file open only
2733 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002735- hashlib has two new constant attributes: algorithms_guaranteed and
2736 algorithms_avaiable that respectively list the names of hash algorithms
2737 guaranteed to exist in all Python implementations and the names of hash
2738 algorithms available in the current process.
2739
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002740- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002830- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2831 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002843- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2844 now removed, since their effect was inexistent in 3.x (the default encoding is

2867 return characters from the full Unicode range, even on narrow unicode builds
2868 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2869 in Python is that unicodedata.numeric() now returns the correct value for
2870 large code points, and repr() may consider more characters as printable.
2871
Victor Stinner6c00c142010-08-17 23:37:11 +00002872- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002896- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2897 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002898

Ezio Melotti57221d02010-07-01 07:32:02 +00003250- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003251 start byte and the continuation byte(s) are now considered invalid, instead of
3252 the number of bytes specified by the start byte. E.g.:
3253 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3254 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3255 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3256 returned a single u'\ufffd'.

3285
Georg Brandl62069d32010-07-31 08:56:11 +00003286- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003287 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3288 location of the raised exception.

Georg Brandl62069d32010-07-31 08:56:11 +00003299- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3300 TypeError instead of giving a DeprecationWarning when a float is parsed using
3301 the 'L' code (for long long). (All other integer codes already raise
3302 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003303
Victor Stinner600d3be2010-06-10 12:00:55 +00003304- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3305 enable shortcuts for upper case encoding name. Add also a shortcut for
3306 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3307
Georg Brandl62069d32010-07-31 08:56:11 +00003308- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3309 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003310
3311- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003312 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003313 like bytearray.
3314
Georg Brandl62069d32010-07-31 08:56:11 +00003315- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003316 used anymore and it was never documented.
3317
Georg Brandl62069d32010-07-31 08:56:11 +00003318- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003322
Georg Brandl62069d32010-07-31 08:56:11 +00003323- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3324 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3325 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3326 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003327
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003328- Issue #8748: Fix two issues with comparisons between complex and integer
3329 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003330 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3331 (2) The comparison raised an OverflowError for large integers, leading to
3332 unpredictable exceptions when combining integers and complex objects in sets
3333 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003334

3337
Victor Stinner9ca9c252010-05-19 16:53:30 +00003338- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003339 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003340 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003341
Georg Brandl62069d32010-07-31 08:56:11 +00003342- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3343 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003344
Victor Stinnerae6265f2010-05-15 16:27:27 +00003345- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3346 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003347 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003348 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003349
Victor Stinner59e62db2010-05-15 13:14:32 +00003350- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003351 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003352
Victor Stinnerb744ba12010-05-15 12:27:16 +00003353- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003354 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003355 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3356
Victor Stinner0964ee12010-04-30 16:48:45 +00003357- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003358 PyUnicode_FromString() to support surrogates in the filename and use the right
3359 encoding.

3637 `va_copy`, but available on all python platforms.
3638
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003639- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3640 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

Antoine Pitrou8689a102010-04-01 16:53:15 +00003651- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003652 function declaration, which was kept for backwards compatibility reasons, is
3653 now removed (the macro was introduced in 1997!).

3663 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3664 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003665 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003675- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3676 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3677 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3691
Georg Brandl62069d32010-07-31 08:56:11 +00003692- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3693 allocator will be automatically disabled when running under Valgrind. This
3694 gives improved memory leak detection when running under Valgrind, while taking
3695 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003770 simply clearing the entire cache on overflow to forgetting the least recently
3771 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003772 applications that use a lot of regular expressions and limits the impact of
3773 the performance hit anytime the cache is exceeded.

3787 defined in datetime with fast C impementation. Python implementation is based
3788 on the original python prototype for the datetime module by Tim Peters with
3789 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004065- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4066 the method could block indefinitely if called just before the event loop
4067 started running. This also fixes the occasional freezes witnessed in
4068 test_httpservers.
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00004069
Georg Brandl62069d32010-07-31 08:56:11 +00004070- Issue #8524: When creating an SSL socket, the timeout value of the original
4071 socket wasn't retained (instead, a socket with a positive timeout would be
4072 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004073
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004074- Issue #5103: SSL handshake would ignore the socket timeout and block
4075 indefinitely if the other end didn't respond.
4076
Georg Brandl62069d32010-07-31 08:56:11 +00004077- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4078 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004079
Georg Brandl62069d32010-07-31 08:56:11 +00004080- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Georg Brandl62069d32010-07-31 08:56:11 +00004089- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4090 string "python" as the *ident*. openlog() arguments are all optional and
4091 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004092
Georg Brandl62069d32010-07-31 08:56:11 +00004093- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4094 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004095 wanting to continue using the socket in clear-text mode, by disabling
4096 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
4097
Antoine Pitrou7062db82010-04-22 13:30:10 +00004098- Issue #8496: make mailcap.lookup() always return a list, rather than an
4099 iterator. Patch by Gregory Nofi.

4130 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
4131
Victor Stinner0e59cc32010-04-16 23:49:32 +00004132- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
4133 the current working directory.
4134
Victor Stinner5bfe1462010-04-16 13:28:05 +00004135- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII

Senthil Kumaranad02d232010-04-16 03:02:13 +00004140- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
4141 Locke and Hans Ulrich Niedermann.
4142
R. David Murrayd48739f2010-04-14 18:59:18 +00004143- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4144
Georg Brandl62069d32010-07-31 08:56:11 +00004145- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004146 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004147 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004148
Victor Stinner485fb562010-04-13 11:07:24 +00004149- Issue #8383: pickle and pickletools use surrogatepass error handler when
4150 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00004151 Python 2.x and 3.x.

R. David Murrayb2416e52010-04-12 16:58:02 +00004153- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004154 filename and date, conforming to the 'standards' they were originally designed
4155 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00004156
R. David Murrayef3d6bd2010-04-12 14:48:58 +00004157- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Antoine Pitrou04f6a322010-04-05 21:40:07 +00004167- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00004168 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4169 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00004170
Raymond Hettingerc50846a2010-04-05 18:56:31 +00004171- Add functools.total_ordering() and functools.cmp_to_key().
4172
Georg Brandl62069d32010-07-31 08:56:11 +00004173- Issue #8257: The Decimal construct now accepts a float instance directly,
4174 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004175
4176 >>> Decimal(1.1)
4177 Decimal('1.100000000000000088817841970012523233890533447265625')
4178
Georg Brandl62069d32010-07-31 08:56:11 +00004179- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4180 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00004181
Georg Brandl62069d32010-07-31 08:56:11 +00004182- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4183 InvalidOperation instead of returning False. (Comparisons involving a quiet
4184 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4185 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004186
Georg Brandl62069d32010-07-31 08:56:11 +00004187- Issue #2531: Comparison operations between floats and Decimal instances now
4188 return a result based on the numeric values of the operands; previously they
4189 returned an arbitrary result based on the relative ordering of id(float) and
4190 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4191 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004192
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004193- Added a subtract() method to collections.Counter().
4194
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004195- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004196 argument `-` which tells it to read files to compile from stdin. Each line is
4197 read on demand and the named file is compiled immediately. (Original patch by
4198 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004199
Florent Xicluna806d8cf2010-03-30 19:34:18 +00004200- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4201 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004202 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004204- Comparisons using one of <, <=, >, >= between a complex instance and a
4205 Fractions instance now raise TypeError instead of returning True/False. This
4206 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4207 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004209- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

4214 running from the build directory (POSIX only).
4215
Antoine Pitrou910bd512010-03-22 20:11:09 +00004216- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004217 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4218 silenced.

4224 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4225 reads and writes are always retried by OpenSSL itself.

4234
Benjamin Peterson00888932010-03-18 22:37:38 +00004235- Issue #8168: py_compile now handles files with utf-8 BOMS.
4236
Benjamin Peterson689a5582010-03-18 22:29:52 +00004237- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
4238 detected.

Georg Brandl62069d32010-07-31 08:56:11 +00004250- The internals of the subprocess module on POSIX systems have been replaced by
4251 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4252 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004253
Georg Brandl62069d32010-07-31 08:56:11 +00004254- subprocess.Popen now has restore_signals and start_new_session features. The
4255 default of restore_signals=True is a new behavior compared to earlier Python
4256 versions. This means that signals such as SIGPIPE are not ignored by default
4257 in subprocesses launched by Python (Issue #1652).

4519 connection with another process, rather than looping endlessly. The default
4520 timeout is 20 seconds, which should be amply sufficient for local connections.

4535 locks as fast as regular non-recursive locks (previously, they were slower by

4785 directive. When the ``%z`` directive is present in the format string, an
4786 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4787 ``datetime.timezone`` instance constructed from the parsed offset. If both
4788 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4789 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00004792 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4793 ``datetime.timezone``, return fixed name and UTC offset from their
4794 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4795 returns ``None``. A class attribute, ``utc`` contains an instance
4796 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004823 the result is now always correctly rounded, and is equivalent to ``td /

Georg Brandl62069d32010-07-31 08:56:11 +00005121 runtest_inner in regrtest, with warnings if the called test modifies them, and

5276 that would raise SystemError.
5277
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005278- Issue #5982: staticmethod and classmethod now expose the wrapped
5279 function with __func__.
5280
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005281- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005284- Issue #5829: complex("1e500") no longer raises OverflowError. This
5285 makes it consistent with float("1e500") and interpretation of real
5286 and imaginary literals.
5287
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005288- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005292- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5293 (1) inf and nan strings with trailing whitespace were incorrectly
5294 rejected; (2) parsing of strings representing infinities and nans
5295 was locale aware; and (3) the interpretation of fromhex('-nan')
5296 didn't match that of float('-nan').

5313
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005314- In unittest, using a skipping decorator on a class is now equivalent to

5319
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005320- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5321 than an int, which makes some operations possible under 64-bit Linux (e.g.
5322 DN_MULTISHOT with F_NOTIFY).
5323
Antoine Pitrou716c4442009-05-23 19:04:03 +00005324- Issue #5761: Add the name of the underlying file to the repr() of various

5345
Antoine Pitroue4501852009-05-14 18:55:55 +00005346- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5347 library. This means, for example, that opening an UTF-16 text file in
5348 append mode doesn't add a BOM at the end of the file if the file isn't
5349 empty.
5350
R. David Murray74b89242009-05-13 17:33:03 +00005351- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

5353 corrects a pydoc regression.
5354
Georg Brandl5f90d792010-08-01 22:31:05 +00005355- Issue #5955: aifc's close method did not close the file it wrapped,

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005398
5399Core and Builtins
5400-----------------
5401
Mark Dickinson865e01a2009-05-07 16:37:01 +00005402- Issue #5914: Add new C API function PyOS_string_to_double, and
5403 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5404
Eric Smith741191f2009-05-06 13:08:15 +00005405- Issue #3382: float.__format__, complex.__format__, and %-formatting
5406 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5407 affects nan -> NAN and inf -> INF.
5408
Mark Hammond5a607a32009-05-06 08:04:54 +00005409- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5410 in all operations, including splitdrive, split, etc. splitunc() now issues
5411 a PendingDeprecation warning.
5412
Eric Smith63376222009-05-05 14:04:18 +00005413- Issue #5920: For float.__format__, change the behavior with the
5414 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5415 to be like 'g' but with at least one decimal point and with a
5416 default precision of 12. Previously, the behavior the same but with
5417 a default precision of 6. This more closely matches str(), and
5418 reduces surprises when adding alignment flags to the empty
5419 presentation type. This also affects the new complex.__format__ in
5420 the same way.
5421
Martin v. Löwis011e8422009-05-05 04:43:17 +00005422- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5423
R. David Murrayb18500d2009-05-04 22:59:07 +00005424- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5425 shadowed by classtype's, even if it was None. property now
5426 inserts the __doc__ into the subclass instance __dict__.
5427
Antoine Pitrou244651a2009-05-04 18:56:13 +00005428- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5429 sequences. Patch by Nick Barnes and Victor Stinner.
5430
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005431- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005432
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005433- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5434 received a new method, detach(). detach() disconnects the underlying stream
5435 from the buffer or text IO and returns it.
5436
Mark Dickinson33841c32009-05-01 15:37:04 +00005437- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5438 floats with absolute value over 1e50. Also remove length
5439 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5440 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005441
Eric Smith741191f2009-05-06 13:08:15 +00005442- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005443 format(complex(1, 2./3), '.5') now produces a sensible result.
5444
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005445- Issue #5864: Fix empty format code formatting for floats so that it
5446 never gives more than the requested number of significant digits.
5447
Eric Smith6dc46f52009-04-27 20:39:49 +00005448- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5449 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5450
Eric Smithcc32a112009-04-26 21:35:14 +00005451- Issue #5835: Deprecate PyOS_ascii_formatd.
5452
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005453- Issue #4971: Fix titlecase for characters that are their own
5454 titlecase, but not their own uppercase.
5455
Benjamin Peterson193152c2009-04-25 01:08:45 +00005456- Issue #5283: Setting __class__ in __del__ caused a segfault.
5457
Mark Dickinsonad476da2009-04-23 19:14:16 +00005458- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5459 z involves nans, infs or negative zeros.
5460
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005461- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005462
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005463- Issue #1869 (and many duplicates): make round(x, n) correctly
5464 rounded for a float x, by using the decimal <-> binary conversions
5465 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5466 consistently agrees with format(x, '.2f').
5467
Benjamin Petersonae937c02009-04-18 20:54:08 +00005468- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5469 some builtin types.
5470
Eric Smith0923d1d2009-04-16 20:16:10 +00005471- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5472
Eric Smith35e84722009-04-16 20:21:28 +00005473- Issue #5515: str.format() type 'n' combined with commas and leading
5474 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005475
5476- Implement PEP 378, Format Specifier for Thousands Separator, for
5477 floats.
5478
Mark Dickinson3370cce2009-04-17 22:40:53 +00005479- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005480 1e11, not 1e12. This avoids printing 13 significant digits in
5481 situations where only 12 of them are correct. Example problem
5482 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5483 long time.)
5484
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005485- Issue #1580: On most platforms, use a 'short' float repr: for a
5486 finite float x, repr(x) now outputs a string based on the shortest
5487 sequence of decimal digits that rounds to x. Previous behaviour was
5488 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005489 Another minor difference is that the new repr switches to
5490 exponential notation at 1e16 instead of the previous 1e17; this
5491 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005492
5493 There's a new sys attribute sys.float_repr_style, which takes
5494 the value 'short' to indicate that we're using short float repr,
5495 and 'legacy' if the short float repr isn't available for one
5496 reason or another.
5497
5498 The float repr change involves incorporating David Gay's 'perfect
5499 rounding' code into the Python core (it's in Python/dtoa.c). As a
5500 secondary consequence, all string-to-float and float-to-string
5501 conversions (including all float formatting operations) will be
5502 correctly rounded on these platforms.
5503
Georg Brandl5f90d792010-08-01 22:31:05 +00005504 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005505 this change does not apply.
5506
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005507- Issue #5759: float() didn't call __float__ on str subclasses.
5508
Georg Brandlabc38772009-04-12 15:51:51 +00005509- The string.maketrans() function is deprecated; there is a new static method
5510 maketrans() on the bytes and bytearray classes. This removes confusion about
5511 the types string.maketrans() is supposed to work with, and mirrors the
5512 methods available on the str class.
5513
R. David Murraydc6da8a2009-04-09 22:16:43 +00005514- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5515 its clarity and its speed.
5516
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005517- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005518 to avoid compiler warnings.
5519
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005520- Issue #3739: The unicode-internal encoder now reports the number of characters
5521 consumed like any other encoder (instead of the number of bytes).

5839
Mark Dickinson8055afd2009-01-17 10:04:45 +00005840- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005841 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005842
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005843- Issue #4935: The overflow checking code in the expandtabs() method common
5844 to str, bytes and bytearray could be optimized away by the compiler, letting
5845 the interpreter segfault instead of raising an error.
5846
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005847- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5848 __next__ method.
5849
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005850- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5851 function no longer attempt to call the __long__ slot to convert an object
5852 to an integer. Only the __int__ and __trunc__ slots are examined.

5857
Antoine Pitrouab868312009-01-10 15:40:25 +00005858- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5859 common cases are optimized thanks to a dedicated fast path and a moderate
5860 amount of loop unrolling.
5861
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005862- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5863 collecting the oldest generation) so that allocating lots of objects without
5864 destroying them does not show quadratic performance. Based on a proposal by
5865 Martin von Löwis at
5866 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5867
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005868- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005869 having been closed (for instance, a read() call could return some
5870 previously buffered data). Patch by Dmitry Vasiliev.
5871
Antoine Pitrou05608432009-01-09 18:53:14 +00005872- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5873 flag to work properly. Furthermore, when specifying -u, the text stdout
5874 and stderr streams have line-by-line buffering enabled (the default being
5875 to buffer arbitrary chunks of data).
5876
Raymond Hettinger35631532009-01-09 03:58:09 +00005877- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5878 instead of ints (reducing its size from 4 to 8 times thereby reducing
5879 Python's overall memory).
5880
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005881- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5882 an existing .py counterpart, override the co_filename attributes of all
5883 code objects if the original filename is obsolete (which can happen if the
5884 file has been renamed, moved, or if it is accessed through different paths).
5885 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5886
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005887- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5888 one byte. Also fixes the meaning of len() so that it returns the number of
5889 items, rather than the size in bytes.
5890
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005891- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005893- Issue #4747: When the terminal does not use utf-8, executing a script with

5895
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005896- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5900 did not get collected.
5901
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005902- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5903 where the tp_hash and tp_dict slots are both NULL.
5904
Georg Brandlccc47b62008-12-28 11:44:14 +00005905- Issue #4759: None is now allowed as the first argument of

5907
Skip Montanaro80072cb2008-12-23 03:51:14 +00005908- Added test case to ensure attempts to read from a file opened for writing
5909 fail.

5915
Antoine Pitrou621601a2008-12-17 23:18:19 +00005916- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5924 failures on OS X.
5925
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005926- Issue #4597: Fixed several opcodes that weren't always propagating
5927 exceptions.
5928
5929- Issue #4589: Fixed exception handling when the __exit__ function of a

5931
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005932- Issue #4445: Replace "sizeof(PyBytesObject)" with
5933 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5934 bytes instances. On a typical machine this saves 3 bytes of memory
5935 (on average) per allocation of a bytes instance.
5936
Christian Heimesa872de52008-12-05 08:26:55 +00005937- Issue #4533: File read operation was dreadfully slow due to a slowly
5938 growing read buffer. Fixed by using the same growth rate algorithm as
5939 Python 2.x.
5940
Antoine Pitrou5504e892008-12-06 21:27:53 +00005941- Issue #4509: Various issues surrounding resize of bytearray objects to
5942 which there are buffer exports (e.g. memoryview instances).
5943
Georg Brandlf9734072008-12-07 15:30:06 +00005944- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5945 method on file objects with closefd=False. The file descriptor is still
5946 kept open but the file object behaves like a closed file. The ``FileIO``
5947 object also got a new readonly attribute ``closefd``.

5955
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005956- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5957 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5958 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5959 of using the replace error handler in PyUnicode_DecodeUTF8().
