9
10Core and Builtins
11-----------------
12
Benjamin Peterson2652d252012-01-29 20:16:37 -050013- Issue #13908: Ready types returned from PyType_FromSpec.
14
Antoine Pitrou2be60af2012-01-24 17:44:06 +010015- Issue #11235: Fix OverflowError when trying to import a source file whose
16 modification time doesn't fit in a 32-bit timestamp.
17
Antoine Pitrou6c40eb72012-01-18 20:16:09 +010018- Fix the builtin module initialization code to store the init function for
19 future reinitialization.
20
Gregory P. Smith9564e4c2012-01-21 14:50:11 -080021- Issue #8052: The posix subprocess module would take a long time closing
22 all possible file descriptors in the child process rather than just open
23 file descriptors. It now closes only the open fds if possible for the
24 default close_fds=True behavior.
25
Meador Inge33880602012-01-15 19:15:36 -060026- Issue #13629: Renumber the tokens in token.h so that they match the indexes
27 into _PyParser_TokenNames.
28
Antoine Pitrou2e872082011-12-15 14:15:31 +010029- Fix the fix for issue #12149: it was incorrect, although it had the side
30 effect of appearing to resolve the issue. Thanks to Mark Shannon for
31 noticing.
32
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050033- Issue #13505: Pickle bytes objects in a way that is compatible with

37 given by Campbell Barton).
38
Antoine Pitrou11942a52011-11-28 19:08:36 +010039- Issue #7111: Python can now be run without a stdin, stdout or stderr
40 stream. It was already the case with Python 2. However, the corresponding
41 sys module entries are now set to None (instead of an unusable file object).
42
Amaury Forgeot d'Arc58e87612011-11-22 21:51:55 +010043- Issue #13436: Fix a bogus error message when an AST object was passed
44 an invalid integer value.
45
Petri Lehtinen8d40f162011-11-19 22:03:10 +020046- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
47 to allow compiling extension modules with -Wswitch-enum on gcc.

49
Antoine Pitrou5418ee02011-11-15 01:42:21 +010050- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
51 already accepts them).
52
Antoine Pitrou0d776b12011-11-06 00:34:26 +010053- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
54 error handler in interactive mode (when calling into PyOS_Readline()).
55
Amaury Forgeot d'Arc97c1bef2011-11-04 22:17:45 +010056- Issue #13343: Fix a SystemError when a lambda expression uses a global
57 variable in the default value of a keyword-only argument:
58 (lambda *, arg=GLOBAL_NAME: None)
59
Petri Lehtinencd06a142011-10-30 20:59:10 +020060- Issue #10519: Avoid unnecessary recursive function calls in
61 setobject.c.
62
Antoine Pitrou8db076c2011-10-30 19:13:55 +010063- Issue #10363: Deallocate global locks in Py_Finalize().

73 warnings. Patch by Josh Triplett and Petri Lehtinen.
74
Antoine Pitrou551ba202011-10-18 16:40:50 +020075- Issue #13188: When called without an explicit traceback argument,
76 generator.throw() now gets the traceback from the passed exception's
77 ``__traceback__`` attribute. Patch by Petri Lehtinen.
78
Mark Hammond6c58b282011-10-17 11:05:57 +110079- Issue #7833: Extension modules built using distutils on Windows will no
80 longer include a "manifest" to prevent them failing at import time in some
81 embedded situations.
82
Antoine Pitrou586bfe42011-10-07 16:16:31 +020083- Issue #13063: the Windows error ERROR_NO_DATA (numbered 232 and described

99 caused test failures with recent versions of Clang.
Mark Dickinsonc0420fd2011-09-19 19:18:37 +0100100

129
Ned Deily99377482012-02-10 13:01:08 +0100130- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
131 Distutils-based packages with C extension modules may fail because
132 Apple has removed gcc-4.2, the version used to build python.org
133 64-bit/32-bit Pythons. If the user does not explicitly override
134 the default C compiler by setting the CC environment variable,
135 Distutils will now attempt to compile extension modules with clang
136 if gcc-4.2 is required but not found. Also as a convenience, if
137 the user does explicitly set CC, substitute its value as the default
138 compiler in the Distutils LDSHARED configuration variable for OS X.
139 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
140 SDK, neither of which are available in Xcode 4. This change does not
141 attempt to override settings to support their use with Xcode 4.)
142
Ezio Melottifa3702d2012-02-10 10:45:44 +0200143- Issue #13960: HTMLParser is now able to handle broken comments when

147
Senthil Kumaran6e13f132012-02-09 17:54:17 +0800148- Issue #6005: Examples in the socket library documentation use sendall, where
149 relevant, instead send method.
150
Petri Lehtinen4a84f582011-05-09 12:24:09 +0200151- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
152 raise a ProgrammingError now.
153
Ned Deilyd531b292012-02-06 00:58:18 +0100154- Issue #10881: Fix test_site failure with OS X framework builds.

184 target's type (file or directory). The detection was buggy and made the
185 call non-atomic (therefore prone to race conditions).

850 and was unreliable since tests or user programs could modify the interpreter
851 environment after Distutils set it. Instead, have Distutils set the the
852 deployment target only in the environment of each build subprocess. It is
853 still possible to globally override the default by setting
854 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
855 greater or equal to the default value, the value with which the interpreter
856 was built.

1591 of HTTP 1.1.

1595 that for incoming headers which makes this behaviour now consistent in
1596 both incoming and outgoing direction.

1718 time.asctime(), time.ctime() and time.strftime() functions will now format
1719 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1720 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1721 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1722 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002353 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002354 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002355 encoding and to encode command line arguments on this OS.

Victor Stinner137c34c2010-09-29 10:25:54 +00002721- Issue #9979: Create function PyUnicode_AsWideCharString().
2722
Brett Cannon5305a992010-09-27 21:08:38 +00002723- Issue #7397: Mention that importlib.import_module() is probably what someone
2724 really wants to be using in __import__'s docstring.
2725
Georg Brandl27a28582010-10-10 09:49:21 +00002726- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2727 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002728
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002729- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002730 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002731
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002732- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2733
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002734- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2735 threads are still running. Instead, reinitialize the GIL on a second call to
2736 Py_Initialize().
2737
Georg Brandl27a28582010-10-10 09:49:21 +00002738- All SyntaxErrors now have a column offset and therefore a caret when the error
2739 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002740
Brett Cannonbc2eff32010-09-19 21:39:02 +00002741- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2742 module that was imported, but instead gets the module from sys.modules.
2743
Nick Coghlan37ee8502010-12-03 14:26:13 +00002744- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002745 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002746
Georg Brandl27a28582010-10-10 09:49:21 +00002747- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2748 with a non-empty format string. This is an effort to future-proof user
2749 code. If a derived class does not currently implement __format__ but later
2750 adds its own __format__, it would most likely break user code that had
2751 supplied a format string. This will be changed to a DeprecationWaring in
2752 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002753
Antoine Pitrou1df15362010-09-13 14:16:46 +00002754- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2755 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2756 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2757
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002758- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2759 functions from the libc caused the methods .upper() and lower() to become
2760 locale aware and created subtly wrong results.
2761
Georg Brandl27a28582010-10-10 09:49:21 +00002762- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2763 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002764
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002765- Issue #4617: Previously it was illegal to delete a name from the local
2766 namespace if it occurs as a free variable in a nested block. This limitation
2767 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2768
Georg Brandl27a28582010-10-10 09:49:21 +00002769- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2770 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2771 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2772 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002773
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002774- Issue #9757: memoryview objects get a release() method to release the
2775 underlying buffer (previously this was only done when deallocating the
2776 memoryview), and gain support for the context management protocol.
2777
Antoine Pitrou079ce542010-09-08 12:37:10 +00002778- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2779 thread-local storage key.
2780
Georg Brandlbad09252010-09-05 21:29:17 +00002781Library
2782-------
2783
Éric Araujo0cfba092010-11-08 21:48:23 +00002784- Issue #2236: distutils' mkpath ignored the mode parameter.
2785
Éric Araujoe7cf9542010-11-06 15:01:07 +00002786- Fix typo in one sdist option (medata-check).
2787
2788- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
2789
2790- Issue #1718574: Fix options that were supposed to accept arguments but did
2791 not in build_clib.
2792
Antoine Pitroudbec7802010-10-10 09:37:12 +00002793- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2794
R. David Murray96fd54e2010-10-08 15:55:28 +00002795- Issue #4661: email can now parse bytes input and generate either converted
2796 7bit output or bytes output. Email version bumped to 5.1.0.
2797
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002798- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2799 verification for higher-level protocols.
2800
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002801- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2802 after the file is closed. Patch by Jeffrey Finkelstein.
2803
Éric Araujo6108bf52010-10-04 23:52:37 +00002804- Issue #9042: Fix interaction of custom translation classes and caching in
2805 gettext.
2806
Éric Araujoef777bd2010-10-05 00:04:20 +00002807- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002808 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002809 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002810 replacement for old handle_accept() and avoids the user to call accept()
2811 directly.
2812
Lars Gustäbel331b8002010-10-04 15:18:47 +00002813- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2814 gname field.
2815
Georg Brandl27a28582010-10-10 09:49:21 +00002816- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2817 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002818
R. David Murray5397e862010-10-02 15:58:26 +00002819- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2820 characters that appear inside quoted strings in email addresses.
2821
Georg Brandl27a28582010-10-10 09:49:21 +00002822- Issue #10004: quoprimime no longer generates a traceback when confronted with
2823 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002824
Georg Brandl27a28582010-10-10 09:49:21 +00002825- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2826 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002827
Georg Brandl27a28582010-10-10 09:49:21 +00002828- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2829 conforms to the philosophy of bytes and unicode separation in Python 3. A
2830 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002831
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002832- Issue #9962: GzipFile now has the peek() method.
2833
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002834- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002835 retry the select() loop instead of bailing out. This is because select() can
2836 incorrectly report a socket as ready for reading (for example, if it received
2837 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002838
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002839- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2840
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002841- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002842 received. Now sendall() properly calls signal handlers if necessary, and
2843 retries sending if these returned successfully, including on sockets with a
2844 timeout.
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002845
Vinay Sajip9fdd11b2010-09-25 17:48:25 +00002846- Issue #9947: logging: Fixed locking bug in stopListening.
2847
Vinay Sajip32fb6a82010-09-25 17:42:36 +00002848- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
2849

2851
Brian Curtin0dac8082010-09-23 20:38:14 +00002852- Issue #9790: Rework imports necessary for samefile and sameopenfile
2853 in ntpath.
2854
Antoine Pitrou70c60442010-09-23 19:51:39 +00002855- Issue #9928: Properly initialize the types exported by the bz2 module.
2856
Georg Brandl27a28582010-10-10 09:49:21 +00002857- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
2858 Florian Festi.
Antoine Pitrou7b969842010-09-23 16:22:51 +00002859
Vinay Sajip0637d492010-09-23 08:15:54 +00002860- Logging: Added QueueListener class to facilitate logging usage for
2861 performance-critical threads.
2862
Barry Warsaw31c604d2010-09-22 20:58:04 +00002863- Issue #9916: Add some missing errno symbols.
2864
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002865- Issue #9877: Expose sysconfig.get_makefile_filename()
2866
2867- logging: Added hasHandlers() method to Logger and LoggerAdapter.
2868
Antoine Pitrou38425292010-09-21 18:19:07 +00002869- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
2870
Antoine Pitrou52d42502010-09-21 16:08:27 +00002871- Issue #2643: msync() is not called anymore when deallocating an open mmap
2872 object, only munmap().
2873
Georg Brandl27a28582010-10-10 09:49:21 +00002874- logging: Changed LoggerAdapter implementation internally, to make it easier to
2875 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002876
Vinay Sajipc84f0162010-09-21 11:25:39 +00002877- logging: hasHandlers method was added to Logger, and isEnabledFor,
2878 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
2879 LoggerAdapter was introduced into the unit tests for logging.
2880
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00002881- Issue #1686: Fix string.Template when overriding the pattern attribute.
2882
Antoine Pitrou98b46702010-09-18 22:59:00 +00002883- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002884 non-blocking mode: they return None when an operation would block (instead of
2885 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002886
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002887- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
2888 another kind.
2889
Vinay Sajip19ec67a2010-09-17 18:57:36 +00002890- Issue #9441: logging has better coverage for rotating file handlers.
2891
Georg Brandl27a28582010-10-10 09:49:21 +00002892- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
Raymond Hettinger35c87f22010-09-16 19:10:17 +00002893
Georg Brandl27a28582010-10-10 09:49:21 +00002894- Issue #9854: The default read() implementation in io.RawIOBase now handles
2895 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002896
Georg Brandl27a28582010-10-10 09:49:21 +00002897- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2898 supporting the whole socket API (rather than the "raw" _socket.socket
2899 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002900
Georg Brandl27a28582010-10-10 09:49:21 +00002901- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2902 to match the corresponding socket methods.
Antoine Pitroua468adc2010-09-14 14:43:44 +00002903
Éric Araujod8c73c62011-03-21 03:15:22 +01002904- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002905 them handle recursive calls within the same thread.
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +00002906
Vinay Sajipaf9d10a2010-09-13 20:40:30 +00002907- logging: Enhanced HTTPHandler with secure and credentials initializers.
2908
Victor Stinnere797c162010-09-17 23:34:26 +00002909- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinnerccb706c2010-09-13 19:41:36 +00002910
Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002911- Issue #9837: The read() method of ZipExtFile objects (as returned by
2912 ZipFile.open()) could return more bytes than requested.
2913
Georg Brandl27a28582010-10-10 09:49:21 +00002914- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2915 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002916
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002917- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002918 it possible for the user to create self-referencing ordered dictionaries which
2919 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002920 approach of using weakref proxies so that reference cycles never get created
2921 in the first place.
2922
Victor Stinnercb043522010-09-10 23:49:04 +00002923- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2924 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002925 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002926
Georg Brandl27a28582010-10-10 09:49:21 +00002927- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2928 environment variable to set the filesystem encoding at Python startup.
2929 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2930 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002931
Georg Brandl27a28582010-10-10 09:49:21 +00002932- Issue #9410: Various optimizations to the pickle module, leading to speedups
2933 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2934 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002935
Georg Brandl27a28582010-10-10 09:49:21 +00002936- The pprint module now supports printing OrderedDicts in their given order
2937 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002938
Vinay Sajip121a1c42010-09-08 10:46:15 +00002939- Logging: Added QueueHandler class to facilitate logging usage with
2940 multiprocessing.
2941
Georg Brandl27a28582010-10-10 09:49:21 +00002942- Issue #9707: Rewritten reference implementation of threading.local which is
2943 friendlier towards reference cycles. This change is not normally visible
2944 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002945
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002946- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2947 still return the id of the parent process after it has exited. This process
2948 id may even have been reused by another unrelated process.
2949
Georg Brandl27a28582010-10-10 09:49:21 +00002950- Issue #9792: In case of connection failure, socket.create_connection() would
2951 swallow the exception and raise a new one, making it impossible to fetch the
2952 original errno, or to filter timeout errors. Now the original error is
2953 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002954
Georg Brandl27a28582010-10-10 09:49:21 +00002955- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2956 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2957 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002958
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002959- Updates to the random module:
2960
Georg Brandl27a28582010-10-10 09:49:21 +00002961 * Document which parts of the module are guaranteed to stay the same across
2962 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002964 * Update the seed() method to use all of the bits in a string instead of just
2965 the hash value. This makes better use of the seed value and assures the
2966 seeding is platform independent. Issue #7889.

3123 return characters from the full Unicode range, even on narrow unicode builds
3124 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3125 in Python is that unicodedata.numeric() now returns the correct value for
3126 large code points, and repr() may consider more characters as printable.

3164 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003165
3166 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003506- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003507 start byte and the continuation byte(s) are now considered invalid, instead of
3508 the number of bytes specified by the start byte. E.g.:
3509 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3510 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3511 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3512 returned a single u'\ufffd'.

Victor Stinner554f3f02010-06-16 23:33:54 +00003532 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003533 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003534

3541
Georg Brandl62069d32010-07-31 08:56:11 +00003542- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003543 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3544 location of the raised exception.
3545
Victor Stinner313a1202010-06-11 23:56:51 +00003546- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3547 filenames and enable os.fsencode().
3548
Benjamin Peterson285a6892010-06-22 19:21:52 +00003549- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3550
Georg Brandl62069d32010-07-31 08:56:11 +00003551- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the

Georg Brandl62069d32010-07-31 08:56:11 +00003555- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3556 TypeError instead of giving a DeprecationWarning when a float is parsed using
3557 the 'L' code (for long long). (All other integer codes already raise
3558 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003559
Victor Stinner600d3be2010-06-10 12:00:55 +00003560- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3561 enable shortcuts for upper case encoding name. Add also a shortcut for
3562 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3563
Georg Brandl62069d32010-07-31 08:56:11 +00003564- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3565 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003566
3567- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003568 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003569 like bytearray.
3570
Georg Brandl62069d32010-07-31 08:56:11 +00003571- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003572 used anymore and it was never documented.
3573
Georg Brandl62069d32010-07-31 08:56:11 +00003574- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003576- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3577 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003578
Georg Brandl62069d32010-07-31 08:56:11 +00003579- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3580 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3581 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3582 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003583
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003584- Issue #8748: Fix two issues with comparisons between complex and integer
3585 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003586 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3587 (2) The comparison raised an OverflowError for large integers, leading to
3588 unpredictable exceptions when combining integers and complex objects in sets
3589 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003590
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003591- Issue #8766: Initialize _warnings module before importing the first module.

3593
Victor Stinner9ca9c252010-05-19 16:53:30 +00003594- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003595 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003596 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003597
Georg Brandl62069d32010-07-31 08:56:11 +00003598- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3599 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003600
Victor Stinnerae6265f2010-05-15 16:27:27 +00003601- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3602 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003603 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003604 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003605
Victor Stinner59e62db2010-05-15 13:14:32 +00003606- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003607 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003608
Victor Stinnerb744ba12010-05-15 12:27:16 +00003609- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003610 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003611 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3612
Victor Stinner0964ee12010-04-30 16:48:45 +00003613- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003614 PyUnicode_FromString() to support surrogates in the filename and use the right
3615 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003616
Georg Brandl8569e582010-05-19 20:57:08 +00003617- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3618
Georg Brandl62069d32010-07-31 08:56:11 +00003619- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003620
Benjamin Petersonfb886362010-04-24 18:21:17 +00003621- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3622 arguments.
3623
Victor Stinner14284c22010-04-23 12:02:30 +00003624- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003625 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003718- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003719 where the right hand operand is a set of constants, by turning the set into a
3720 frozenset and pre-building it as a constant. The comparison operation is made
3721 against the constant instead of building a new set each time it is executed (a
3722 similar optimization already existed which turned a list of constants into a
3723 pre-built tuple). Patch and additional tests by Dave Malcolm.

3750 least on IEEE 754 platforms), and in particular does not depend on the
3751 internal representation of an int.

4027 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004028 applications that use a lot of regular expressions and limits the impact of
4029 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004438- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4439 InvalidOperation instead of returning False. (Comparisons involving a quiet
4440 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4441 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004443- Issue #2531: Comparison operations between floats and Decimal instances now
4444 return a result based on the numeric values of the operands; previously they
4445 returned an arbitrary result based on the relative ordering of id(float) and
4446 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4447 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004448
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004449- Added a subtract() method to collections.Counter().
4450
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004451- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004452 argument `-` which tells it to read files to compile from stdin. Each line is
4453 read on demand and the named file is compiled immediately. (Original patch by
4454 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004456- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004460- Comparisons using one of <, <=, >, >= between a complex instance and a
4461 Fractions instance now raise TypeError instead of returning True/False. This
4462 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4463 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004506- The internals of the subprocess module on POSIX systems have been replaced by
4507 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4508 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004509
Georg Brandl62069d32010-07-31 08:56:11 +00004510- subprocess.Popen now has restore_signals and start_new_session features. The
4511 default of restore_signals=True is a new behavior compared to earlier Python
4512 versions. This means that signals such as SIGPIPE are not ignored by default
4513 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004599- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4600 position when calling `truncate()`. It would previously change the file
4601 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004602 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004604- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004605 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4606 archive. The new implementation is significantly faster and can be wrapped in
4607 a :class:`io.BufferedReader` object for more speedups. It also solves an
4608 issue where interleaved calls to `read()` and `readline()` give wrong results.
4609 Patch by Nir Aides.

Georg Brandl62069d32010-07-31 08:56:11 +00005007 compared to other unix systems. In particular, os.getgroups() does not reflect

5569
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005570- In unittest, using a skipping decorator on a class is now equivalent to
5571 skipping every test on the class. The ClassTestSuite class has been removed.
5572
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005573- Issue #6050: Don't fail extracting a directory from a zipfile if

5575
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005576- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5577 than an int, which makes some operations possible under 64-bit Linux (e.g.
5578 DN_MULTISHOT with F_NOTIFY).
5579
Antoine Pitrou716c4442009-05-23 19:04:03 +00005580- Issue #5761: Add the name of the underlying file to the repr() of various

5584 by Musashi Tamura, tests by Marcin Bachry.
5585
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005586- Issue #1983: Fix functions taking or returning a process identifier to use
5587 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5588 a process identifier type wider than the standard C integer type.
5589

5601
Antoine Pitroue4501852009-05-14 18:55:55 +00005602- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5603 library. This means, for example, that opening an UTF-16 text file in
5604 append mode doesn't add a BOM at the end of the file if the file isn't
5605 empty.
5606
R. David Murray74b89242009-05-13 17:33:03 +00005607- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5608 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5609 corrects a pydoc regression.
5610
Georg Brandl5f90d792010-08-01 22:31:05 +00005611- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005612 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005654
5655Core and Builtins
5656-----------------
5657
Mark Dickinson865e01a2009-05-07 16:37:01 +00005658- Issue #5914: Add new C API function PyOS_string_to_double, and
5659 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5660
Eric Smith741191f2009-05-06 13:08:15 +00005661- Issue #3382: float.__format__, complex.__format__, and %-formatting
5662 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5663 affects nan -> NAN and inf -> INF.
5664
Mark Hammond5a607a32009-05-06 08:04:54 +00005665- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5666 in all operations, including splitdrive, split, etc. splitunc() now issues
5667 a PendingDeprecation warning.
5668
Eric Smith63376222009-05-05 14:04:18 +00005669- Issue #5920: For float.__format__, change the behavior with the
5670 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5671 to be like 'g' but with at least one decimal point and with a
5672 default precision of 12. Previously, the behavior the same but with
5673 a default precision of 6. This more closely matches str(), and
5674 reduces surprises when adding alignment flags to the empty
5675 presentation type. This also affects the new complex.__format__ in
5676 the same way.
5677
Martin v. Löwis011e8422009-05-05 04:43:17 +00005678- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5679
R. David Murrayb18500d2009-05-04 22:59:07 +00005680- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5681 shadowed by classtype's, even if it was None. property now
5682 inserts the __doc__ into the subclass instance __dict__.
5683
Antoine Pitrou244651a2009-05-04 18:56:13 +00005684- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5685 sequences. Patch by Nick Barnes and Victor Stinner.
5686
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005687- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005688
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005689- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5690 received a new method, detach(). detach() disconnects the underlying stream
5691 from the buffer or text IO and returns it.
5692
Mark Dickinson33841c32009-05-01 15:37:04 +00005693- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5694 floats with absolute value over 1e50. Also remove length
5695 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5696 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005697
Eric Smith741191f2009-05-06 13:08:15 +00005698- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005699 format(complex(1, 2./3), '.5') now produces a sensible result.
5700
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005701- Issue #5864: Fix empty format code formatting for floats so that it
5702 never gives more than the requested number of significant digits.
5703
Eric Smith6dc46f52009-04-27 20:39:49 +00005704- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5705 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5706
Eric Smithcc32a112009-04-26 21:35:14 +00005707- Issue #5835: Deprecate PyOS_ascii_formatd.
5708
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005709- Issue #4971: Fix titlecase for characters that are their own
5710 titlecase, but not their own uppercase.
5711
Benjamin Peterson193152c2009-04-25 01:08:45 +00005712- Issue #5283: Setting __class__ in __del__ caused a segfault.
5713
Mark Dickinsonad476da2009-04-23 19:14:16 +00005714- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5715 z involves nans, infs or negative zeros.
5716
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005717- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005718
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005719- Issue #1869 (and many duplicates): make round(x, n) correctly
5720 rounded for a float x, by using the decimal <-> binary conversions
5721 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5722 consistently agrees with format(x, '.2f').
5723
Benjamin Petersonae937c02009-04-18 20:54:08 +00005724- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5725 some builtin types.
5726
Eric Smith0923d1d2009-04-16 20:16:10 +00005727- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5728
Eric Smith35e84722009-04-16 20:21:28 +00005729- Issue #5515: str.format() type 'n' combined with commas and leading
5730 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005731
5732- Implement PEP 378, Format Specifier for Thousands Separator, for
5733 floats.
5734
Mark Dickinson3370cce2009-04-17 22:40:53 +00005735- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005736 1e11, not 1e12. This avoids printing 13 significant digits in
5737 situations where only 12 of them are correct. Example problem
5738 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5739 long time.)
5740
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005741- Issue #1580: On most platforms, use a 'short' float repr: for a
5742 finite float x, repr(x) now outputs a string based on the shortest
5743 sequence of decimal digits that rounds to x. Previous behaviour was
5744 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005745 Another minor difference is that the new repr switches to
5746 exponential notation at 1e16 instead of the previous 1e17; this
5747 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005748
5749 There's a new sys attribute sys.float_repr_style, which takes
5750 the value 'short' to indicate that we're using short float repr,
5751 and 'legacy' if the short float repr isn't available for one
5752 reason or another.
5753
5754 The float repr change involves incorporating David Gay's 'perfect
5755 rounding' code into the Python core (it's in Python/dtoa.c). As a
5756 secondary consequence, all string-to-float and float-to-string
5757 conversions (including all float formatting operations) will be
5758 correctly rounded on these platforms.
5759
Georg Brandl5f90d792010-08-01 22:31:05 +00005760 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005761 this change does not apply.
5762
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005763- Issue #5759: float() didn't call __float__ on str subclasses.
5764
Georg Brandlabc38772009-04-12 15:51:51 +00005765- The string.maketrans() function is deprecated; there is a new static method
5766 maketrans() on the bytes and bytearray classes. This removes confusion about
5767 the types string.maketrans() is supposed to work with, and mirrors the
5768 methods available on the str class.
5769
R. David Murraydc6da8a2009-04-09 22:16:43 +00005770- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5771 its clarity and its speed.
5772
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005773- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005774 to avoid compiler warnings.
5775
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005776- Issue #3739: The unicode-internal encoder now reports the number of characters
5777 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00005857- Issue #1161031: fix readwrite select flag handling: POLLPRI now
5858 results in a handle_expt_event call, not handle_read_event, and POLLERR
5859 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5860 dispatcher now has an 'ignore_log_types' attribute for suppressing
5861 log messages, which is set to 'warning' by default.

5935
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005936- Issue #4688: Add a heuristic so that tuples and dicts containing only
5937 untrackable objects are not tracked by the garbage collector. This can
5938 reduce the size of collections and therefore the garbage collection overhead
5939 on long-running programs, depending on their particular use of datatypes.

5954 and sizeof(Py_UNICODE) == 2.
5955
Eric Smith8ec90442009-03-14 12:29:34 +00005956- Issue #5237: Allow auto-numbered fields in str.format(). For

Lars Gustäbel42e00912009-03-22 20:34:29 +00006009- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6010 forever on incomplete input. That caused tarfile.open() to hang when used
6011 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6012 partial bzip2 compressed data.
6013
Mark Dickinson79f52032009-03-17 23:12:51 +00006014- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006125 having been closed (for instance, a read() call could return some
6126 previously buffered data). Patch by Dmitry Vasiliev.
6127
Antoine Pitrou05608432009-01-09 18:53:14 +00006128- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6129 flag to work properly. Furthermore, when specifying -u, the text stdout
6130 and stderr streams have line-by-line buffering enabled (the default being
6131 to buffer arbitrary chunks of data).
6132
Raymond Hettinger35631532009-01-09 03:58:09 +00006133- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6134 instead of ints (reducing its size from 4 to 8 times thereby reducing
6135 Python's overall memory).
6136
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006137- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6138 an existing .py counterpart, override the co_filename attributes of all
6139 code objects if the original filename is obsolete (which can happen if the
6140 file has been renamed, moved, or if it is accessed through different paths).

6146

6177
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006178- Issue #2173: When getting device encoding, check that return value of

6189 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

6195 Python 2.x.
6196
Antoine Pitrou5504e892008-12-06 21:27:53 +00006197- Issue #4509: Various issues surrounding resize of bytearray objects to

Georg Brandlf9734072008-12-07 15:30:06 +00006200- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``

6202 kept open but the file object behaves like a closed file. The ``FileIO``
6203 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006204

6213 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6214 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6215 of using the replace error handler in PyUnicode_DecodeUTF8().

6534
Antoine Pitrou08838b62009-01-21 00:55:13 +00006535- Issue #5008: When a file is opened in append mode with the new IO library,
6536 do an explicit seek to the end of file (so that e.g. tell() returns the
6537 file size rather than 0). This is consistent with the behaviour of the

6568 appropriately when it is being used via socket.makefile() objects
6569 rather than delaying the close by waiting for garbage collection to do it.
6570
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006571- Issue #1696199: Add collections.Counter() for rapid and convenient
