714 and was unreliable since tests or user programs could modify the interpreter
715 environment after Distutils set it. Instead, have Distutils set the the
716 deployment target only in the environment of each build subprocess. It is
717 still possible to globally override the default by setting
718 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
719 greater or equal to the default value, the value with which the interpreter
720 was built.

Victor Stinner4ee65a92011-01-22 10:30:29 +00001441 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1442 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001443 for all file entries in the ZIP file.

1452
Armin Ronacher8d96d772011-01-22 13:13:05 +00001453- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1454 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1455 of HTTP 1.1.
1456
Armin Ronacher59531282011-01-22 13:44:22 +00001457- To match the behaviour of HTTP server, the HTTP client library now also
1458 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1459 that for incoming headers which makes this behaviour now consistent in
1460 both incoming and outgoing direction.

1497 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001560- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001561 continuation line in the formatted value has no leading white space and looks
1562 like a header. Since Generator uses Header to format all headers, this check
1563 is made for all headers in any serialized message at serialization time. This
1564 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001565

Éric Araujof0ab5d62011-05-29 03:43:59 +02001573 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001574 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001575
Éric Araujof0ab5d62011-05-29 03:43:59 +02001576- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001577 rfc2047-encoding header values with embedded newlines, leaving them without
1578 folding whitespace. It now uses the continuation_ws, as it does for
1579 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001581- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1582 time.asctime(), time.ctime() and time.strftime() functions will now format
1583 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1584 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1585 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1586 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Antoine Pitroue85da7a2011-01-06 18:25:55 +00001588- Issue #7858: Raise an error properly when os.utime() fails under Windows

1595 compilation (if the input is a string).
1596
Antoine Pitrou600232b2011-01-05 21:03:42 +00001597- Issue #7995: When calling accept() on a socket with a timeout, the returned

Georg Brandl27a28582010-10-10 09:49:21 +00002569- ast.literal_eval() can now handle negative numbers. It is also a little more

2601
Georg Brandl27a28582010-10-10 09:49:21 +00002602- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002611- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2612 with a non-empty format string. This is an effort to future-proof user
2613 code. If a derived class does not currently implement __format__ but later
2614 adds its own __format__, it would most likely break user code that had
2615 supplied a format string. This will be changed to a DeprecationWaring in
2616 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002618- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2620 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002622- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2623 functions from the libc caused the methods .upper() and lower() to become
2624 locale aware and created subtly wrong results.
2625
Georg Brandl27a28582010-10-10 09:49:21 +00002626- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2627 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002628
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002629- Issue #4617: Previously it was illegal to delete a name from the local
2630 namespace if it occurs as a free variable in a nested block. This limitation
2631 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2632
Georg Brandl27a28582010-10-10 09:49:21 +00002633- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2634 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2635 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2636 single character on UCS-2 builds.

2640 memoryview), and gain support for the context management protocol.
2641
Antoine Pitrou079ce542010-09-08 12:37:10 +00002642- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00002671- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002672 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002673 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002674 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002699 retry the select() loop instead of bailing out. This is because select() can
2700 incorrectly report a socket as ready for reading (for example, if it received
2701 some data with an invalid checksum).

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002705- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002706 received. Now sendall() properly calls signal handlers if necessary, and
2707 retries sending if these returned successfully, including on sockets with a
2708 timeout.

Georg Brandl27a28582010-10-10 09:49:21 +00002748 non-blocking mode: they return None when an operation would block (instead of
2749 raising an exception).

Georg Brandl27a28582010-10-10 09:49:21 +00002761- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2762 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002781- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002782 it possible for the user to create self-referencing ordered dictionaries which
2783 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002784 approach of using weakref proxies so that reference cycles never get created
2785 in the first place.
2786
Victor Stinnercb043522010-09-10 23:49:04 +00002787- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002791- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2792 environment variable to set the filesystem encoding at Python startup.
2793 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2794 reencode all filenames in all objects.

2805
Georg Brandl27a28582010-10-10 09:49:21 +00002806- Issue #9707: Rewritten reference implementation of threading.local which is
2807 friendlier towards reference cycles. This change is not normally visible
2808 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002810- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2811 still return the id of the parent process after it has exited. This process
2812 id may even have been reused by another unrelated process.
2813
Georg Brandl27a28582010-10-10 09:49:21 +00002814- Issue #9792: In case of connection failure, socket.create_connection() would
2815 swallow the exception and raise a new one, making it impossible to fetch the
2816 original errno, or to filter timeout errors. Now the original error is
2817 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002819- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2820 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2821 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002823- Updates to the random module:
2824
Georg Brandl27a28582010-10-10 09:49:21 +00002825 * Document which parts of the module are guaranteed to stay the same across
2826 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002828 * Update the seed() method to use all of the bits in a string instead of just
2829 the hash value. This makes better use of the seed value and assures the
2830 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002831
Georg Brandl27a28582010-10-10 09:49:21 +00002832 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2833 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2834 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002835
2836 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002855- hashlib has two new constant attributes: algorithms_guaranteed and
2856 algorithms_avaiable that respectively list the names of hash algorithms
2857 guaranteed to exist in all Python implementations and the names of hash
2858 algorithms available in the current process.
2859
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002860- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002950- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2951 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2952 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00002953
Brett Cannonef0e6c32010-09-04 18:24:04 +00002954- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Georg Brandl649971e2010-09-05 17:06:50 +00002963- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2964 now removed, since their effect was inexistent in 3.x (the default encoding is
2965 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002966
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002967- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2969
Georg Brandl649971e2010-09-05 17:06:50 +00002970- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2971 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002972
Benjamin Peterson33856de2010-08-30 14:41:20 +00002973- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
2974
Benjamin Peterson0e102062010-08-25 23:13:17 +00002975- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
2976
Georg Brandl649971e2010-09-05 17:06:50 +00002977- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
2978 the pyconfig.h generated by configure on other systems.
Daniel Stutzbach864078a2010-08-25 19:18:59 +00002979
Georg Brandl649971e2010-09-05 17:06:50 +00002980- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that

2987 return characters from the full Unicode range, even on narrow unicode builds
2988 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2989 in Python is that unicodedata.numeric() now returns the correct value for
2990 large code points, and repr() may consider more characters as printable.
2991
Victor Stinner6c00c142010-08-17 23:37:11 +00002992- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2993 as a unicode object, instead of a byte string. Function needed to support
2994 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2995 function.
2996
Victor Stinner6961bd62010-08-17 22:26:51 +00002997- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

3005 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00003006 sys.stderr.
3007
Victor Stinner47fcb5b2010-08-13 23:59:58 +00003008- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003009 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3010 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00003011
Georg Brandl649971e2010-09-05 17:06:50 +00003012- Issue #9203: Computed gotos are now enabled by default on supported compilers
3013 (which are detected by the configure script). They can still be disable
3014 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003015
Georg Brandl649971e2010-09-05 17:06:50 +00003016- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3017 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003018
Georg Brandl649971e2010-09-05 17:06:50 +00003019- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
3020 array.

Georg Brandl649971e2010-09-05 17:06:50 +00003024- Issue #9337: The str() of a float or complex number is now identical to its
3025 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003026
Georg Brandl649971e2010-09-05 17:06:50 +00003027- Issue #9416: Fix some issues with complex formatting where the output with no
3028 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003029
3030 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3031 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00003371 start byte and the continuation byte(s) are now considered invalid, instead of
3372 the number of bytes specified by the start byte. E.g.:

3374 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3375 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3376 returned a single u'\ufffd'.

3783 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3784 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003785 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003888- The default size of the re module's compiled regular expression cache has been
3889 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003890 simply clearing the entire cache on overflow to forgetting the least recently
3891 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003892 applications that use a lot of regular expressions and limits the impact of
3893 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003905- Issue #7989: Added pure python implementation of the `datetime` module. The C
3906 module is renamed to `_datetime` and if available, overrides all classes
3907 defined in datetime with fast C impementation. Python implementation is based
3908 on the original python prototype for the datetime module by Tim Peters with
3909 minor modifications by the PyPy project. The test suite now tests `datetime`
3910 module with and without `_datetime` acceleration using the same test cases.

4138
Victor Stinnerd17f2192010-08-15 09:56:07 +00004139- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00004140 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00004147- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4148 operation raises multiple signals and more than one of those signals is
4149 trapped, the specification determines the order in which the signals should be
4150 handled. In many cases this order wasn't being followed, leading to the wrong
4151 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00004152
Antoine Pitrou6be88762010-05-03 16:48:20 +00004153- Issue #7865: The close() method of :mod:`io` objects should not swallow

Georg Brandl62069d32010-07-31 08:56:11 +00004185- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4186 the method could block indefinitely if called just before the event loop
4187 started running. This also fixes the occasional freezes witnessed in

Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00004189
Georg Brandl62069d32010-07-31 08:56:11 +00004190- Issue #8524: When creating an SSL socket, the timeout value of the original
4191 socket wasn't retained (instead, a socket with a positive timeout would be
4192 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004193
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004194- Issue #5103: SSL handshake would ignore the socket timeout and block
4195 indefinitely if the other end didn't respond.
4196
Georg Brandl62069d32010-07-31 08:56:11 +00004197- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004209- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4210 string "python" as the *ident*. openlog() arguments are all optional and
4211 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004212
Georg Brandl62069d32010-07-31 08:56:11 +00004213- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4214 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004215 wanting to continue using the socket in clear-text mode, by disabling
4216 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004266 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004267 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004268

R. David Murrayb2416e52010-04-12 16:58:02 +00004273- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004274 filename and date, conforming to the 'standards' they were originally designed
4275 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004291- Add functools.total_ordering() and functools.cmp_to_key().
4292
Georg Brandl62069d32010-07-31 08:56:11 +00004293- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00004302- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4303 InvalidOperation instead of returning False. (Comparisons involving a quiet
4304 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4305 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004306
Georg Brandl62069d32010-07-31 08:56:11 +00004307- Issue #2531: Comparison operations between floats and Decimal instances now
4308 return a result based on the numeric values of the operands; previously they
4309 returned an arbitrary result based on the relative ordering of id(float) and
4310 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4311 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004312
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004313- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004315- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004316 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandl62069d32010-07-31 08:56:11 +00004324- Comparisons using one of <, <=, >, >= between a complex instance and a
4325 Fractions instance now raise TypeError instead of returning True/False. This
4326 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4327 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00004336- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004337 didn't support chflags() (for example ZFS under FreeBSD). The error is now

4371 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4372 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004373
Georg Brandl62069d32010-07-31 08:56:11 +00004374- subprocess.Popen now has restore_signals and start_new_session features. The
4375 default of restore_signals=True is a new behavior compared to earlier Python
4376 versions. This means that signals such as SIGPIPE are not ignored by default
4377 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004378

Georg Brandl62069d32010-07-31 08:56:11 +00004463- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4464 position when calling `truncate()`. It would previously change the file
4465 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004466 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4467
Antoine Pitroua32f9a22010-01-27 21:18:57 +00004468- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004469 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4470 archive. The new implementation is significantly faster and can be wrapped in
4471 a :class:`io.BufferedReader` object for more speedups. It also solves an
4472 issue where interleaved calls to `read()` and `readline()` give wrong results.
4473 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004808- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004809 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4810 PyPycLoader inherit from this class and provide implementations in relation to
4811 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004812
Brett Cannon64ef00f2009-07-20 03:19:18 +00004813- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4814 the documentation said it did even though the code in PyLoader relied on the
4815 abstract method required by ResourceLoader.
4816
Georg Brandl62069d32010-07-31 08:56:11 +00004817- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004865- Issue #9959: Tweak formula used for computing math.log of an integer,
4866 making it marginally more accurate for exact powers of 2.
4867
Mark Dickinsoncf28b952010-07-29 21:41:59 +00004868- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4869
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004870- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004871 compared to other unix systems. In particular, os.getgroups() does not reflect
4872 any changes made using os.setgroups() but basicly always returns the same
4873 information as the id command. os.getgroups() can now return more than 16
4874 groups on MacOSX.

4879 struct.pack('>?')): if conversion to bool raised an exception then that
4880 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00004881

4895
Benjamin Petersonf751bc92010-07-02 13:46:42 +00004896- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as

Georg Brandl62069d32010-07-31 08:56:11 +00004899- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4900 Prior to this change, timezone adjustment in utctimetuple() could produce
4901 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4902 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004904- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4905 directive. When the ``%z`` directive is present in the format string, an
4906 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4907 ``datetime.timezone`` instance constructed from the parsed offset. If both
4908 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4909 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004910
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004911- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004912 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4913 ``datetime.timezone``, return fixed name and UTC offset from their
4914 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4915 returns ``None``. A class attribute, ``utc`` contains an instance
4916 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004932- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4933 with an improved 'binary-split' algorithm that uses fewer multiplications and
4934 allows many of the multiplications to be performed using plain C integer
4935 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4936 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004941- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4942 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004943 the result is now always correctly rounded, and is equivalent to ``td /
4944 timedelta(seconds=1)``.

4953 integer format code, struct.pack first attempts to convert the non-integer
4954 using its __index__ method. If that method is non-existent or raises
4955 TypeError it goes on to try the __int__ method, as described below.

5535 to be like 'g' but with at least one decimal point and with a
5536 default precision of 12. Previously, the behavior the same but with
5537 a default precision of 6. This more closely matches str(), and
5538 reduces surprises when adding alignment flags to the empty
5539 presentation type. This also affects the new complex.__format__ in
5540 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00005542- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

5554 received a new method, detach(). detach() disconnects the underlying stream
5555 from the buffer or text IO and returns it.
5556
Mark Dickinson33841c32009-05-01 15:37:04 +00005557- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5558 floats with absolute value over 1e50. Also remove length
5559 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005583- Issue #1869 (and many duplicates): make round(x, n) correctly
5584 rounded for a float x, by using the decimal <-> binary conversions
5585 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5586 consistently agrees with format(x, '.2f').
5587
Benjamin Petersonae937c02009-04-18 20:54:08 +00005588- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00005591- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5592
Eric Smith35e84722009-04-16 20:21:28 +00005593- Issue #5515: str.format() type 'n' combined with commas and leading
5594 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005595
5596- Implement PEP 378, Format Specifier for Thousands Separator, for
5597 floats.
5598
Mark Dickinson3370cce2009-04-17 22:40:53 +00005599- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005600 1e11, not 1e12. This avoids printing 13 significant digits in
5601 situations where only 12 of them are correct. Example problem
5602 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5603 long time.)
5604
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005605- Issue #1580: On most platforms, use a 'short' float repr: for a
5606 finite float x, repr(x) now outputs a string based on the shortest
5607 sequence of decimal digits that rounds to x. Previous behaviour was
5608 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005609 Another minor difference is that the new repr switches to
5610 exponential notation at 1e16 instead of the previous 1e17; this
5611 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005612
5613 There's a new sys attribute sys.float_repr_style, which takes
5614 the value 'short' to indicate that we're using short float repr,
5615 and 'legacy' if the short float repr isn't available for one
5616 reason or another.
5617
5618 The float repr change involves incorporating David Gay's 'perfect
5619 rounding' code into the Python core (it's in Python/dtoa.c). As a
5620 secondary consequence, all string-to-float and float-to-string
5621 conversions (including all float formatting operations) will be
5622 correctly rounded on these platforms.
5623
Georg Brandl5f90d792010-08-01 22:31:05 +00005624 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005625 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005627- Issue #5759: float() didn't call __float__ on str subclasses.
5628
Georg Brandlabc38772009-04-12 15:51:51 +00005629- The string.maketrans() function is deprecated; there is a new static method
5630 maketrans() on the bytes and bytearray classes. This removes confusion about
5631 the types string.maketrans() is supposed to work with, and mirrors the
5632 methods available on the str class.
5633
R. David Murraydc6da8a2009-04-09 22:16:43 +00005634- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5924 rotating the object pointer by 4 bits to the right.
5925
Mark Dickinson87ec0852009-02-09 17:15:59 +00005926- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5927 it now forces its argument to double before testing for infinity.
5928
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005929- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5930 returns a non-number type.
5931
Benjamin Peterson87618552009-02-08 15:00:52 +00005932- Issue #5182: Removed memoryview.__str__.
5933
Mark Dickinsonc008a172009-02-01 13:59:22 +00005934- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5935 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005936 the type definition cmpfunc. The tp_compare slot has been renamed
5937 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005938
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005939- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005940 were suppressing all exceptions. These include list() and bytearray().
5941
Mark Dickinson1124e712009-01-28 21:25:58 +00005942- Issue #4707: round(x, n) now returns an integer if x is an integer.
5943 Previously it returned a float.
5944
Antoine Pitroub52ec782009-01-25 16:34:23 +00005945- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5946 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5947 evaluation loop is compiled with a new dispatch mechanism which gives
5948 speedups of up to 20%, depending on the system, on various benchmarks.
5949
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005950- Issue #4874: Most builtin decoders now reject unicode input.

5958 optional module state data.
5959
Mark Dickinson8055afd2009-01-17 10:04:45 +00005960- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005961 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005962
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005963- Issue #4935: The overflow checking code in the expandtabs() method common
5964 to str, bytes and bytearray could be optimized away by the compiler, letting
5965 the interpreter segfault instead of raising an error.
5966
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005967- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5968 __next__ method.
5969
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005970- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5971 function no longer attempt to call the __long__ slot to convert an object
5972 to an integer. Only the __int__ and __trunc__ slots are examined.
5973
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005974- Issue #4893: Use NT threading on CE.
5975
Martin v. Löwisec59d042009-01-12 07:59:10 +00005976- Issue #4915: Port sysmodule to Windows CE.
5977
Antoine Pitrouab868312009-01-10 15:40:25 +00005978- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5979 common cases are optimized thanks to a dedicated fast path and a moderate
5980 amount of loop unrolling.
5981
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005982- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5983 collecting the oldest generation) so that allocating lots of objects without
5984 destroying them does not show quadratic performance. Based on a proposal by
5985 Martin von Löwis at
5986 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5987
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005988- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005989 having been closed (for instance, a read() call could return some
5990 previously buffered data). Patch by Dmitry Vasiliev.
5991
Antoine Pitrou05608432009-01-09 18:53:14 +00005992- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5993 flag to work properly. Furthermore, when specifying -u, the text stdout
5994 and stderr streams have line-by-line buffering enabled (the default being
5995 to buffer arbitrary chunks of data).
5996
Raymond Hettinger35631532009-01-09 03:58:09 +00005997- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5998 instead of ints (reducing its size from 4 to 8 times thereby reducing
5999 Python's overall memory).
6000
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006001- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6002 an existing .py counterpart, override the co_filename attributes of all
6003 code objects if the original filename is obsolete (which can happen if the
6004 file has been renamed, moved, or if it is accessed through different paths).
6005 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6006
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006007- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6008 one byte. Also fixes the meaning of len() so that it returns the number of
6009 items, rather than the size in bytes.
6010
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006011- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6012
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006013- Issue #4747: When the terminal does not use utf-8, executing a script with
6014 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6015
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006016- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6017 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006018
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006019- Issue #3680: Reference cycles created through a dict, set or deque iterator
6020 did not get collected.
6021
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006022- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6023 where the tp_hash and tp_dict slots are both NULL.
6024
Georg Brandlccc47b62008-12-28 11:44:14 +00006025- Issue #4759: None is now allowed as the first argument of
6026 bytearray.translate(). It was always allowed for bytes.translate().
6027
Skip Montanaro80072cb2008-12-23 03:51:14 +00006028- Added test case to ensure attempts to read from a file opened for writing
6029 fail.
6030
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006031- Issue #3106: Speedup some comparisons (str/str and int/int).

6035
Antoine Pitrou621601a2008-12-17 23:18:19 +00006036- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6037 print elapsed times, not only when some objects are uncollectable /
6038 unreachable. Original patch by Neil Schemenauer.
6039
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006040- Issue #3439: Add a bit_length method to int.
6041
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006042- Issue #2173: When getting device encoding, check that return value of
6043 nl_langinfo is not the empty string. This was causing silent build
6044 failures on OS X.
6045
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006046- Issue #4597: Fixed several opcodes that weren't always propagating
6047 exceptions.
6048
6049- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006050 context manager returns a value that cannot be converted to a bool.
6051
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006052- Issue #4445: Replace "sizeof(PyBytesObject)" with
6053 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6054 bytes instances. On a typical machine this saves 3 bytes of memory
6055 (on average) per allocation of a bytes instance.
6056
Christian Heimesa872de52008-12-05 08:26:55 +00006057- Issue #4533: File read operation was dreadfully slow due to a slowly
6058 growing read buffer. Fixed by using the same growth rate algorithm as
6059 Python 2.x.
6060
Antoine Pitrou5504e892008-12-06 21:27:53 +00006061- Issue #4509: Various issues surrounding resize of bytearray objects to
6062 which there are buffer exports (e.g. memoryview instances).
6063
Georg Brandlf9734072008-12-07 15:30:06 +00006064- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6065 method on file objects with closefd=False. The file descriptor is still
6066 kept open but the file object behaves like a closed file. The ``FileIO``
6067 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006068
Antoine Pitroubc420402008-12-07 20:14:49 +00006069- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6070 larger than 1.

6075
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006076- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6077 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6078 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6079 of using the replace error handler in PyUnicode_DecodeUTF8().
