357 Condition, etc.) used to be factory functions returning instances of hidden
358 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

Ned Deily657b2de2011-06-28 19:51:30 -0700505- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
506 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
507 interpreter process. This could cause failures in non-Distutils subprocesses
508 and was unreliable since tests or user programs could modify the interpreter
509 environment after Distutils set it. Instead, have Distutils set the the
510 deployment target only in the environment of each build subprocess. It is
511 still possible to globally override the default by setting
512 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
513 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700514 was built. Also, implement the same handling in packaging.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001699- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001700 continuation line in the formatted value has no leading white space and looks
1701 like a header. Since Generator uses Header to format all headers, this check
1702 is made for all headers in any serialized message at serialization time. This
1703 provides protection against header injection attacks.

Łukasz Langa1ac0d7a2010-12-16 01:42:36 +00002227- Issue #10499: configparser supports pluggable interpolation handlers. The
2228 default classic interpolation handler is called BasicInterpolation. Another

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002356- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2357 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002358 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002359 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002360 encoding and to encode command line arguments on this OS.

2363 filenames encoded to the filesystem encoding with the surrogateescape error

2365
Benjamin Peterson230b2062010-10-16 03:45:45 +00002366- Issue #9997: Don't let the name "top" have special significance in scope

2702-----------------
2703
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002704- Issue #10068: Global objects which have reference cycles with their module's
2705 dict are now cleared again. This causes issue #7140 to appear again.
2706
Victor Stinner257d38f2010-10-09 10:12:11 +00002707- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002708 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002709
Georg Brandl27a28582010-10-10 09:49:21 +00002710- ast.literal_eval() can now handle negative numbers. It is also a little more
2711 liberal in what it accepts without compromising the safety of the evaluation.
2712 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002713
Benjamin Peterson970d1882010-10-02 17:55:47 +00002714- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2715 result metaclasses can now be ABCs (see #9533).
2716
Victor Stinneraef57e32010-10-02 11:50:49 +00002717- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2718
Victor Stinner5593d8a2010-10-02 11:11:27 +00002719- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002720 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2721 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002722
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002723- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002724 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002725
Victor Stinner137c34c2010-09-29 10:25:54 +00002726- Issue #9979: Create function PyUnicode_AsWideCharString().
2727
Brett Cannon5305a992010-09-27 21:08:38 +00002728- Issue #7397: Mention that importlib.import_module() is probably what someone
2729 really wants to be using in __import__'s docstring.
2730
Georg Brandl27a28582010-10-10 09:49:21 +00002731- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2732 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002733
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002734- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002735 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002736
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002737- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2738
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002739- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2740 threads are still running. Instead, reinitialize the GIL on a second call to
2741 Py_Initialize().
2742
Georg Brandl27a28582010-10-10 09:49:21 +00002743- All SyntaxErrors now have a column offset and therefore a caret when the error
2744 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002745
Brett Cannonbc2eff32010-09-19 21:39:02 +00002746- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2747 module that was imported, but instead gets the module from sys.modules.
2748
Nick Coghlan37ee8502010-12-03 14:26:13 +00002749- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002750 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002751
Georg Brandl27a28582010-10-10 09:49:21 +00002752- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2753 with a non-empty format string. This is an effort to future-proof user
2754 code. If a derived class does not currently implement __format__ but later
2755 adds its own __format__, it would most likely break user code that had
2756 supplied a format string. This will be changed to a DeprecationWaring in
2757 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002758
Antoine Pitrou1df15362010-09-13 14:16:46 +00002759- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2760 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2761 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2762
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002763- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2764 functions from the libc caused the methods .upper() and lower() to become
2765 locale aware and created subtly wrong results.
2766
Georg Brandl27a28582010-10-10 09:49:21 +00002767- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2768 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002769
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002770- Issue #4617: Previously it was illegal to delete a name from the local
2771 namespace if it occurs as a free variable in a nested block. This limitation
2772 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2773
Georg Brandl27a28582010-10-10 09:49:21 +00002774- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2775 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2776 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2777 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002778
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002779- Issue #9757: memoryview objects get a release() method to release the
2780 underlying buffer (previously this was only done when deallocating the
2781 memoryview), and gain support for the context management protocol.
2782
Antoine Pitrou079ce542010-09-08 12:37:10 +00002783- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2784 thread-local storage key.
2785
Georg Brandlbad09252010-09-05 21:29:17 +00002786Library
2787-------
2788
Éric Araujo0cfba092010-11-08 21:48:23 +00002789- Issue #2236: distutils' mkpath ignored the mode parameter.
2790
Éric Araujoe7cf9542010-11-06 15:01:07 +00002791- Fix typo in one sdist option (medata-check).
2792
2793- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
2794
2795- Issue #1718574: Fix options that were supposed to accept arguments but did
2796 not in build_clib.
2797
Antoine Pitroudbec7802010-10-10 09:37:12 +00002798- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2799
R. David Murray96fd54e2010-10-08 15:55:28 +00002800- Issue #4661: email can now parse bytes input and generate either converted
2801 7bit output or bytes output. Email version bumped to 5.1.0.
2802
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002803- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2804 verification for higher-level protocols.
2805
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002806- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2807 after the file is closed. Patch by Jeffrey Finkelstein.
2808
Éric Araujo6108bf52010-10-04 23:52:37 +00002809- Issue #9042: Fix interaction of custom translation classes and caching in
2810 gettext.
2811
Éric Araujoef777bd2010-10-05 00:04:20 +00002812- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002813 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002814 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002815 replacement for old handle_accept() and avoids the user to call accept()
2816 directly.
2817
Lars Gustäbel331b8002010-10-04 15:18:47 +00002818- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2819 gname field.
2820
Georg Brandl27a28582010-10-10 09:49:21 +00002821- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2822 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002823
R. David Murray5397e862010-10-02 15:58:26 +00002824- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2825 characters that appear inside quoted strings in email addresses.
2826
Georg Brandl27a28582010-10-10 09:49:21 +00002827- Issue #10004: quoprimime no longer generates a traceback when confronted with
2828 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002829
Georg Brandl27a28582010-10-10 09:49:21 +00002830- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2831 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002832
Georg Brandl27a28582010-10-10 09:49:21 +00002833- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2834 conforms to the philosophy of bytes and unicode separation in Python 3. A
2835 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002836
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002837- Issue #9962: GzipFile now has the peek() method.
2838
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002839- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002840 retry the select() loop instead of bailing out. This is because select() can
2841 incorrectly report a socket as ready for reading (for example, if it received
2842 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002843
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002844- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2845
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002846- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002847 received. Now sendall() properly calls signal handlers if necessary, and
2848 retries sending if these returned successfully, including on sockets with a
2849 timeout.

2858 in ntpath.
2859
Antoine Pitrou70c60442010-09-23 19:51:39 +00002860- Issue #9928: Properly initialize the types exported by the bz2 module.
2861
Georg Brandl27a28582010-10-10 09:49:21 +00002862- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
2863 Florian Festi.

Vinay Sajip0637d492010-09-23 08:15:54 +00002865- Logging: Added QueueListener class to facilitate logging usage for
2866 performance-critical threads.
2867
Barry Warsaw31c604d2010-09-22 20:58:04 +00002868- Issue #9916: Add some missing errno symbols.
2869

2872- logging: Added hasHandlers() method to Logger and LoggerAdapter.
2873
Antoine Pitrou38425292010-09-21 18:19:07 +00002874- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
2875
Antoine Pitrou52d42502010-09-21 16:08:27 +00002876- Issue #2643: msync() is not called anymore when deallocating an open mmap
2877 object, only munmap().
2878
Georg Brandl27a28582010-10-10 09:49:21 +00002879- logging: Changed LoggerAdapter implementation internally, to make it easier to
2880 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002881
Vinay Sajipc84f0162010-09-21 11:25:39 +00002882- logging: hasHandlers method was added to Logger, and isEnabledFor,
2883 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
2884 LoggerAdapter was introduced into the unit tests for logging.
2885
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00002886- Issue #1686: Fix string.Template when overriding the pattern attribute.
2887
Antoine Pitrou98b46702010-09-18 22:59:00 +00002888- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002889 non-blocking mode: they return None when an operation would block (instead of
2890 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002891
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002892- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
2893 another kind.
2894

Georg Brandl27a28582010-10-10 09:49:21 +00002899- Issue #9854: The default read() implementation in io.RawIOBase now handles
2900 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002901
Georg Brandl27a28582010-10-10 09:49:21 +00002902- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2903 supporting the whole socket API (rather than the "raw" _socket.socket
2904 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002905
Georg Brandl27a28582010-10-10 09:49:21 +00002906- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2907 to match the corresponding socket methods.
Antoine Pitroua468adc2010-09-14 14:43:44 +00002908
Éric Araujod8c73c62011-03-21 03:15:22 +01002909- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002910 them handle recursive calls within the same thread.

Raymond Hettingerdc08a142010-09-12 05:15:22 +00002921
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002922- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002923 it possible for the user to create self-referencing ordered dictionaries which
2924 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002925 approach of using weakref proxies so that reference cycles never get created
2926 in the first place.
2927
Victor Stinnercb043522010-09-10 23:49:04 +00002928- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2929 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002930 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002932- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2933 environment variable to set the filesystem encoding at Python startup.
2934 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2935 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002936
Georg Brandl27a28582010-10-10 09:49:21 +00002937- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00002941- The pprint module now supports printing OrderedDicts in their given order
2942 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002943
Vinay Sajip121a1c42010-09-08 10:46:15 +00002944- Logging: Added QueueHandler class to facilitate logging usage with
2945 multiprocessing.
2946
Georg Brandl27a28582010-10-10 09:49:21 +00002947- Issue #9707: Rewritten reference implementation of threading.local which is
2948 friendlier towards reference cycles. This change is not normally visible
2949 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002950
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002951- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2952 still return the id of the parent process after it has exited. This process
2953 id may even have been reused by another unrelated process.
2954
Georg Brandl27a28582010-10-10 09:49:21 +00002955- Issue #9792: In case of connection failure, socket.create_connection() would
2956 swallow the exception and raise a new one, making it impossible to fetch the
2957 original errno, or to filter timeout errors. Now the original error is
2958 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002959
Georg Brandl27a28582010-10-10 09:49:21 +00002960- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2961 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2962 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002963
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002964- Updates to the random module:
2965
Georg Brandl27a28582010-10-10 09:49:21 +00002966 * Document which parts of the module are guaranteed to stay the same across
2967 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002968
Georg Brandl27a28582010-10-10 09:49:21 +00002969 * Update the seed() method to use all of the bits in a string instead of just
2970 the hash value. This makes better use of the seed value and assures the
2971 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002972
Georg Brandl27a28582010-10-10 09:49:21 +00002973 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2974 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2975 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002976
2977 * Improved documentation of arguments to randrange(). Issue #9379.
Raymond Hettingerf763a722010-09-07 00:38:15 +00002978
Georg Brandl27a28582010-10-10 09:49:21 +00002979- collections.OrderedDict now supports a new method for repositioning keys to
2980 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00002981
Georg Brandl27a28582010-10-10 09:49:21 +00002982- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2983 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2984 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002985
Georg Brandl27a28582010-10-10 09:49:21 +00002986- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2987 their contents without duplicating them. The view is both readable and
2988 writable.
Antoine Pitrou972ee132010-09-06 18:48:21 +00002989
Brian Curtin62857742010-09-06 17:07:27 +00002990- Issue #7566: Implement os.path.sameopenfile for Windows.
2991
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002992- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002993 unsupported operation is attempted (for example, writing to a file open only
2994 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002995
Gregory P. Smith13b55292010-09-06 08:30:23 +00002996- hashlib has two new constant attributes: algorithms_guaranteed and
2997 algorithms_avaiable that respectively list the names of hash algorithms
2998 guaranteed to exist in all Python implementations and the names of hash
2999 algorithms available in the current process.
3000
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003001- A new package ``concurrent.futures`` as defined by PEP 3148.

Benjamin Peterson568867a2010-09-11 16:02:03 +00003008- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
3009 PySequence_DelSlice when the object doesn't have any mapping operations
3010 defined.

Georg Brandl27a28582010-10-10 09:49:21 +00003015- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
3016 wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
3017 and the interpreter under test.

Georg Brandl649971e2010-09-05 17:06:50 +00003104- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3105 now removed, since their effect was inexistent in 3.x (the default encoding is
3106 hardcoded to utf-8 and cannot be changed).

3128 return characters from the full Unicode range, even on narrow unicode builds
3129 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3130 in Python is that unicodedata.numeric() now returns the correct value for
3131 large code points, and repr() may consider more characters as printable.
3132
Victor Stinner6c00c142010-08-17 23:37:11 +00003133- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003157- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3158 use PyUnicode_FromFormatV() to format the warning message.

3166 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003167
Georg Brandl649971e2010-09-05 17:06:50 +00003168- Issue #9416: Fix some issues with complex formatting where the output with no
3169 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003170
3171 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3172 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00003511- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003512 start byte and the continuation byte(s) are now considered invalid, instead of
3513 the number of bytes specified by the start byte. E.g.:
3514 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3515 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3516 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3517 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003519- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3520 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00003531- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3532 dealing with unary minus applied to a constant. The removed code was mutating
3533 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003534
Victor Stinner554f3f02010-06-16 23:33:54 +00003535- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003536 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003537 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003538 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003539
Victor Stinner25e8ec42010-06-25 00:02:38 +00003540- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3541 "w*" format instead. Add tests for "w*" format.
3542
Victor Stinner06e49dd2010-06-13 18:21:50 +00003543- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003544 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003545 string formats.
3546
Georg Brandl62069d32010-07-31 08:56:11 +00003547- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003548 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3549 location of the raised exception.
3550
Victor Stinner313a1202010-06-11 23:56:51 +00003551- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3552 filenames and enable os.fsencode().
3553
Benjamin Peterson285a6892010-06-22 19:21:52 +00003554- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3555
Georg Brandl62069d32010-07-31 08:56:11 +00003556- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3557 interpreter with characters outside the Basic Multilingual Plane (higher than
3558 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003559
Georg Brandl62069d32010-07-31 08:56:11 +00003560- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3561 TypeError instead of giving a DeprecationWarning when a float is parsed using
3562 the 'L' code (for long long). (All other integer codes already raise
3563 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003564
Victor Stinner600d3be2010-06-10 12:00:55 +00003565- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3566 enable shortcuts for upper case encoding name. Add also a shortcut for
3567 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3568
Georg Brandl62069d32010-07-31 08:56:11 +00003569- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3570 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003571
3572- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003573 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003574 like bytearray.
3575
Georg Brandl62069d32010-07-31 08:56:11 +00003576- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003577 used anymore and it was never documented.
3578
Georg Brandl62069d32010-07-31 08:56:11 +00003579- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003580
Georg Brandl62069d32010-07-31 08:56:11 +00003581- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3582 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003583
Georg Brandl62069d32010-07-31 08:56:11 +00003584- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3585 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3586 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3587 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003588
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003589- Issue #8748: Fix two issues with comparisons between complex and integer
3590 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003591 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3592 (2) The comparison raised an OverflowError for large integers, leading to
3593 unpredictable exceptions when combining integers and complex objects in sets
3594 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003595
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003596- Issue #8766: Initialize _warnings module before importing the first module.
3597 Fix a crash if an empty directory called "encodings" exists in sys.path.
3598
Victor Stinner9ca9c252010-05-19 16:53:30 +00003599- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003600 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003601 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003602
Georg Brandl62069d32010-07-31 08:56:11 +00003603- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3604 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003605
Victor Stinnerae6265f2010-05-15 16:27:27 +00003606- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3607 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003608 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003609 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003610
Victor Stinner59e62db2010-05-15 13:14:32 +00003611- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003612 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003613
Victor Stinnerb744ba12010-05-15 12:27:16 +00003614- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003615 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003616 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3617
Victor Stinner0964ee12010-04-30 16:48:45 +00003618- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003619 PyUnicode_FromString() to support surrogates in the filename and use the right
3620 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003622- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3623
Georg Brandl62069d32010-07-31 08:56:11 +00003624- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003625
Benjamin Petersonfb886362010-04-24 18:21:17 +00003626- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3627 arguments.
3628
Victor Stinner14284c22010-04-23 12:02:30 +00003629- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003630 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003896- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3897 variable argument list. `Py_VA_COPY` is equivalent to C99
3898 `va_copy`, but available on all python platforms.
3899
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003900- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3901 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3902 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003912- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003913 function declaration, which was kept for backwards compatibility reasons, is

3924 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3925 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003926 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003936- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3937 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3938 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00003953- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3954 allocator will be automatically disabled when running under Valgrind. This
3955 gives improved memory leak detection when running under Valgrind, while taking
3956 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00004031 simply clearing the entire cache on overflow to forgetting the least recently
4032 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004033 applications that use a lot of regular expressions and limits the impact of
4034 the performance hit anytime the cache is exceeded.

4048 defined in datetime with fast C impementation. Python implementation is based
4049 on the original python prototype for the datetime module by Tim Peters with
4050 minor modifications by the PyPy project. The test suite now tests `datetime`

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004407 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004408 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00004443- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4444 InvalidOperation instead of returning False. (Comparisons involving a quiet
4445 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4446 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004448- Issue #2531: Comparison operations between floats and Decimal instances now
4449 return a result based on the numeric values of the operands; previously they
4450 returned an arbitrary result based on the relative ordering of id(float) and
4451 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4452 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004453
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004454- Added a subtract() method to collections.Counter().
4455
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004456- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004457 argument `-` which tells it to read files to compile from stdin. Each line is
4458 read on demand and the named file is compiled immediately. (Original patch by
4459 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004461- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004465- Comparisons using one of <, <=, >, >= between a complex instance and a
4466 Fractions instance now raise TypeError instead of returning True/False. This
4467 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4468 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004511- The internals of the subprocess module on POSIX systems have been replaced by
4512 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4513 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004514
Georg Brandl62069d32010-07-31 08:56:11 +00004515- subprocess.Popen now has restore_signals and start_new_session features. The
4516 default of restore_signals=True is a new behavior compared to earlier Python
4517 versions. This means that signals such as SIGPIPE are not ignored by default
4518 in subprocesses launched by Python (Issue #1652).

5041 Prior to this change, timezone adjustment in utctimetuple() could produce
5042 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5043 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005045- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5046 directive. When the ``%z`` directive is present in the format string, an
5047 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5048 ``datetime.timezone`` instance constructed from the parsed offset. If both
5049 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5050 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005052- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005053 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5054 ``datetime.timezone``, return fixed name and UTC offset from their
5055 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5056 returns ``None``. A class attribute, ``utc`` contains an instance
5057 representing the UTC timezone. Original patch by Rafe Kaplan.

5554 (1) inf and nan strings with trailing whitespace were incorrectly
5555 rejected; (2) parsing of strings representing infinities and nans
5556 was locale aware; and (3) the interpretation of fromhex('-nan')
5557 didn't match that of float('-nan').

5660Core and Builtins
5661-----------------
5662
Mark Dickinson865e01a2009-05-07 16:37:01 +00005663- Issue #5914: Add new C API function PyOS_string_to_double, and
5664 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5665
Eric Smith741191f2009-05-06 13:08:15 +00005666- Issue #3382: float.__format__, complex.__format__, and %-formatting
5667 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5668 affects nan -> NAN and inf -> INF.
5669
Mark Hammond5a607a32009-05-06 08:04:54 +00005670- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5671 in all operations, including splitdrive, split, etc. splitunc() now issues
5672 a PendingDeprecation warning.
5673
Eric Smith63376222009-05-05 14:04:18 +00005674- Issue #5920: For float.__format__, change the behavior with the
5675 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5676 to be like 'g' but with at least one decimal point and with a
5677 default precision of 12. Previously, the behavior the same but with
5678 a default precision of 6. This more closely matches str(), and
5679 reduces surprises when adding alignment flags to the empty
5680 presentation type. This also affects the new complex.__format__ in
5681 the same way.
5682
Martin v. Löwis011e8422009-05-05 04:43:17 +00005683- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5684
R. David Murrayb18500d2009-05-04 22:59:07 +00005685- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5686 shadowed by classtype's, even if it was None. property now
5687 inserts the __doc__ into the subclass instance __dict__.
5688
Antoine Pitrou244651a2009-05-04 18:56:13 +00005689- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5690 sequences. Patch by Nick Barnes and Victor Stinner.
5691
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005692- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005693
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005694- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5695 received a new method, detach(). detach() disconnects the underlying stream
5696 from the buffer or text IO and returns it.
5697
Mark Dickinson33841c32009-05-01 15:37:04 +00005698- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5699 floats with absolute value over 1e50. Also remove length
5700 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5701 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005702
Eric Smith741191f2009-05-06 13:08:15 +00005703- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005704 format(complex(1, 2./3), '.5') now produces a sensible result.
5705
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005706- Issue #5864: Fix empty format code formatting for floats so that it
5707 never gives more than the requested number of significant digits.
5708
Eric Smith6dc46f52009-04-27 20:39:49 +00005709- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5710 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5711
Eric Smithcc32a112009-04-26 21:35:14 +00005712- Issue #5835: Deprecate PyOS_ascii_formatd.
5713
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005714- Issue #4971: Fix titlecase for characters that are their own
5715 titlecase, but not their own uppercase.
5716
Benjamin Peterson193152c2009-04-25 01:08:45 +00005717- Issue #5283: Setting __class__ in __del__ caused a segfault.
5718
Mark Dickinsonad476da2009-04-23 19:14:16 +00005719- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5720 z involves nans, infs or negative zeros.
5721
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005722- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005723
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005724- Issue #1869 (and many duplicates): make round(x, n) correctly
5725 rounded for a float x, by using the decimal <-> binary conversions
5726 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5727 consistently agrees with format(x, '.2f').
5728
Benjamin Petersonae937c02009-04-18 20:54:08 +00005729- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5730 some builtin types.
5731
Eric Smith0923d1d2009-04-16 20:16:10 +00005732- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5733
Eric Smith35e84722009-04-16 20:21:28 +00005734- Issue #5515: str.format() type 'n' combined with commas and leading
5735 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005736
5737- Implement PEP 378, Format Specifier for Thousands Separator, for
5738 floats.
5739
Mark Dickinson3370cce2009-04-17 22:40:53 +00005740- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005741 1e11, not 1e12. This avoids printing 13 significant digits in
5742 situations where only 12 of them are correct. Example problem
5743 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5744 long time.)
5745
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005746- Issue #1580: On most platforms, use a 'short' float repr: for a
5747 finite float x, repr(x) now outputs a string based on the shortest
5748 sequence of decimal digits that rounds to x. Previous behaviour was
5749 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005750 Another minor difference is that the new repr switches to
5751 exponential notation at 1e16 instead of the previous 1e17; this
5752 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005753
5754 There's a new sys attribute sys.float_repr_style, which takes
5755 the value 'short' to indicate that we're using short float repr,
5756 and 'legacy' if the short float repr isn't available for one
5757 reason or another.
5758
5759 The float repr change involves incorporating David Gay's 'perfect
5760 rounding' code into the Python core (it's in Python/dtoa.c). As a
5761 secondary consequence, all string-to-float and float-to-string
5762 conversions (including all float formatting operations) will be
5763 correctly rounded on these platforms.
5764
Georg Brandl5f90d792010-08-01 22:31:05 +00005765 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005766 this change does not apply.
5767
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005768- Issue #5759: float() didn't call __float__ on str subclasses.
5769
Georg Brandlabc38772009-04-12 15:51:51 +00005770- The string.maketrans() function is deprecated; there is a new static method
5771 maketrans() on the bytes and bytearray classes. This removes confusion about
5772 the types string.maketrans() is supposed to work with, and mirrors the
5773 methods available on the str class.
5774
R. David Murraydc6da8a2009-04-09 22:16:43 +00005775- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5776 its clarity and its speed.
5777
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005778- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005779 to avoid compiler warnings.
5780
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005781- Issue #3739: The unicode-internal encoder now reports the number of characters
5782 consumed like any other encoder (instead of the number of bytes).

6113 to an integer. Only the __int__ and __trunc__ slots are examined.

6118
Antoine Pitrouab868312009-01-10 15:40:25 +00006119- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6120 common cases are optimized thanks to a dedicated fast path and a moderate
6121 amount of loop unrolling.
6122
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006123- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6124 collecting the oldest generation) so that allocating lots of objects without
6125 destroying them does not show quadratic performance. Based on a proposal by
6126 Martin von Löwis at
6127 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6128
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006129- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006130 having been closed (for instance, a read() call could return some
6131 previously buffered data). Patch by Dmitry Vasiliev.
6132
Antoine Pitrou05608432009-01-09 18:53:14 +00006133- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6134 flag to work properly. Furthermore, when specifying -u, the text stdout
6135 and stderr streams have line-by-line buffering enabled (the default being
6136 to buffer arbitrary chunks of data).
6137
Raymond Hettinger35631532009-01-09 03:58:09 +00006138- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6139 instead of ints (reducing its size from 4 to 8 times thereby reducing
6140 Python's overall memory).
6141
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006142- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6143 an existing .py counterpart, override the co_filename attributes of all
6144 code objects if the original filename is obsolete (which can happen if the
6145 file has been renamed, moved, or if it is accessed through different paths).
6146 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6147
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006148- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6149 one byte. Also fixes the meaning of len() so that it returns the number of
6150 items, rather than the size in bytes.
6151
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006152- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006154- Issue #4747: When the terminal does not use utf-8, executing a script with

6156
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006157- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

6162
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006163- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6164 where the tp_hash and tp_dict slots are both NULL.
6165
Georg Brandlccc47b62008-12-28 11:44:14 +00006166- Issue #4759: None is now allowed as the first argument of
6167 bytearray.translate(). It was always allowed for bytes.translate().
6168
Skip Montanaro80072cb2008-12-23 03:51:14 +00006169- Added test case to ensure attempts to read from a file opened for writing
6170 fail.

6176
Antoine Pitrou621601a2008-12-17 23:18:19 +00006177- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

6185 failures on OS X.
6186
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006187- Issue #4597: Fixed several opcodes that weren't always propagating

6189
6190- Issue #4589: Fixed exception handling when the __exit__ function of a

6192
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006193- Issue #4445: Replace "sizeof(PyBytesObject)" with
6194 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6195 bytes instances. On a typical machine this saves 3 bytes of memory
6196 (on average) per allocation of a bytes instance.
6197
Christian Heimesa872de52008-12-05 08:26:55 +00006198- Issue #4533: File read operation was dreadfully slow due to a slowly
6199 growing read buffer. Fixed by using the same growth rate algorithm as
6200 Python 2.x.
6201
Antoine Pitrou5504e892008-12-06 21:27:53 +00006202- Issue #4509: Various issues surrounding resize of bytearray objects to
6203 which there are buffer exports (e.g. memoryview instances).
6204
Georg Brandlf9734072008-12-07 15:30:06 +00006205- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6206 method on file objects with closefd=False. The file descriptor is still
6207 kept open but the file object behaves like a closed file. The ``FileIO``
6208 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00006210- Issue #4569: Interpreter crash when mutating a memoryview with an item size

6216
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006217- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6218 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6219 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6220 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00006540- Issue #5008: When a file is opened in append mode with the new IO library,
6541 do an explicit seek to the end of file (so that e.g. tell() returns the

6573 appropriately when it is being used via socket.makefile() objects
6574 rather than delaying the close by waiting for garbage collection to do it.
