Ned Deily657b2de2011-06-28 19:51:30 -0700816- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
817 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
818 interpreter process. This could cause failures in non-Distutils subprocesses
819 and was unreliable since tests or user programs could modify the interpreter
820 environment after Distutils set it. Instead, have Distutils set the the
821 deployment target only in the environment of each build subprocess. It is
822 still possible to globally override the default by setting
823 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
824 greater or equal to the default value, the value with which the interpreter

Steven Bethardb0270112011-01-24 21:02:50 +00001966
1967- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001968 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Georg Brandl255abdd2011-01-16 14:17:26 +00002067 continuation line in the formatted value has no leading white space and looks
2068 like a header. Since Generator uses Header to format all headers, this check
2069 is made for all headers in any serialized message at serialization time. This
2070 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00002071

Georg Brandl255abdd2011-01-16 14:17:26 +00002080 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002081
Éric Araujof0ab5d62011-05-29 03:43:59 +02002082- email.header.Header was incorrectly encoding folding whitespace when

2084 folding whitespace. It now uses the continuation_ws, as it does for

2090 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2091 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2092 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

3122 with a non-empty format string. This is an effort to future-proof user
3123 code. If a derived class does not currently implement __format__ but later
3124 adds its own __format__, it would most likely break user code that had
3125 supplied a format string. This will be changed to a DeprecationWaring in
3126 Python 3.3 and it will be an error in Python 3.4.

3130 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 +00003132- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3133 functions from the libc caused the methods .upper() and lower() to become
3134 locale aware and created subtly wrong results.
3135
Georg Brandl27a28582010-10-10 09:49:21 +00003136- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3137 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003138
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003139- Issue #4617: Previously it was illegal to delete a name from the local
3140 namespace if it occurs as a free variable in a nested block. This limitation
3141 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3142
Georg Brandl27a28582010-10-10 09:49:21 +00003143- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3144 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3145 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3146 single character on UCS-2 builds.

3150 memoryview), and gain support for the context management protocol.
3151
Antoine Pitrou079ce542010-09-08 12:37:10 +00003152- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003181- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method

Georg Brandl27a28582010-10-10 09:49:21 +00003183 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003184 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003208- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003209 retry the select() loop instead of bailing out. This is because select() can
3210 incorrectly report a socket as ready for reading (for example, if it received
3211 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00003216 received. Now sendall() properly calls signal handlers if necessary, and
3217 retries sending if these returned successfully, including on sockets with a
3218 timeout.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003291- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003292 it possible for the user to create self-referencing ordered dictionaries which
3293 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003294 approach of using weakref proxies so that reference cycles never get created
3295 in the first place.
3296
Victor Stinnercb043522010-09-10 23:49:04 +00003297- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00003301- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3302 environment variable to set the filesystem encoding at Python startup.
3303 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3304 reencode all filenames in all objects.

3315
Georg Brandl27a28582010-10-10 09:49:21 +00003316- Issue #9707: Rewritten reference implementation of threading.local which is
3317 friendlier towards reference cycles. This change is not normally visible
3318 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003320- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3321 still return the id of the parent process after it has exited. This process
3322 id may even have been reused by another unrelated process.
3323
Georg Brandl27a28582010-10-10 09:49:21 +00003324- Issue #9792: In case of connection failure, socket.create_connection() would
3325 swallow the exception and raise a new one, making it impossible to fetch the
3326 original errno, or to filter timeout errors. Now the original error is
3327 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003329- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3330 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3331 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003333- Updates to the random module:
3334
Georg Brandl27a28582010-10-10 09:49:21 +00003335 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003338 * Update the seed() method to use all of the bits in a string instead of just
3339 the hash value. This makes better use of the seed value and assures the
3340 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003341
Georg Brandl27a28582010-10-10 09:49:21 +00003342 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3343 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3344 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003345
3346 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003365- hashlib has two new constant attributes: algorithms_guaranteed and
3366 algorithms_avaiable that respectively list the names of hash algorithms
3367 guaranteed to exist in all Python implementations and the names of hash
3368 algorithms available in the current process.
3369

Georg Brandl649971e2010-09-05 17:06:50 +00003460- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3461 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
3462 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00003463
Brett Cannonef0e6c32010-09-04 18:24:04 +00003464- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
3465 confusion with the proper variables names from 'warnings' itself.
3466

Georg Brandl649971e2010-09-05 17:06:50 +00003470- Issue #9737: Fix a crash when trying to delete a slice or an item from a
3471 memoryview object.
Antoine Pitroue0793ba2010-09-01 21:14:16 +00003472
Georg Brandl649971e2010-09-05 17:06:50 +00003473- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3474 now removed, since their effect was inexistent in 3.x (the default encoding is
3475 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003476
Antoine Pitroub0fa8312010-09-01 15:10:12 +00003477- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
3478 properly. Patch by Stefan Behnel.
3479
Georg Brandl649971e2010-09-05 17:06:50 +00003480- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3481 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00003482
Benjamin Peterson33856de2010-08-30 14:41:20 +00003483- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
3484
Benjamin Peterson0e102062010-08-25 23:13:17 +00003485- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
3486
Georg Brandl649971e2010-09-05 17:06:50 +00003487- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
3488 the pyconfig.h generated by configure on other systems.
Daniel Stutzbach864078a2010-08-25 19:18:59 +00003489
Georg Brandl649971e2010-09-05 17:06:50 +00003490- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
3491 occur during attribute lookup are now propagated to the caller.
Benjamin Peterson17689992010-08-24 03:26:23 +00003492

3495
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00003496- Issue #5127: The C functions that access the Unicode Database now accept and
3497 return characters from the full Unicode range, even on narrow unicode builds
3498 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3499 in Python is that unicodedata.numeric() now returns the correct value for
3500 large code points, and repr() may consider more characters as printable.
3501
Victor Stinner6c00c142010-08-17 23:37:11 +00003502- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
3503 as a unicode object, instead of a byte string. Function needed to support
3504 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3505 function.
3506
Victor Stinner6961bd62010-08-17 22:26:51 +00003507- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
3508
Antoine Pitrou671b4d92010-08-17 17:55:07 +00003509- Issue #9612: The set object is now 64-bit clean under Windows.
3510
Georg Brandl649971e2010-09-05 17:06:50 +00003511- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
3512 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00003513

3515 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00003516 sys.stderr.
3517
Victor Stinner47fcb5b2010-08-13 23:59:58 +00003518- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003519 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3520 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00003521
Georg Brandl649971e2010-09-05 17:06:50 +00003522- Issue #9203: Computed gotos are now enabled by default on supported compilers
3523 (which are detected by the configure script). They can still be disable
3524 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003525
Georg Brandl649971e2010-09-05 17:06:50 +00003526- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3527 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003528
Georg Brandl649971e2010-09-05 17:06:50 +00003529- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
3530 array.
Florent Xiclunaeb6f3ea2010-08-08 22:07:16 +00003531

Antoine Pitroubddc9fe2010-08-08 20:46:42 +00003533
Georg Brandl649971e2010-09-05 17:06:50 +00003534- Issue #9337: The str() of a float or complex number is now identical to its
3535 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003536
Georg Brandl649971e2010-09-05 17:06:50 +00003537- Issue #9416: Fix some issues with complex formatting where the output with no
3538 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003539
3540 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3541 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00003916- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003917 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3918 location of the raised exception.
3919
Victor Stinner313a1202010-06-11 23:56:51 +00003920- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3921 filenames and enable os.fsencode().

Georg Brandl62069d32010-07-31 08:56:11 +00003929- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3930 TypeError instead of giving a DeprecationWarning when a float is parsed using
3931 the 'L' code (for long long). (All other integer codes already raise
3932 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003933
Victor Stinner600d3be2010-06-10 12:00:55 +00003934- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3935 enable shortcuts for upper case encoding name. Add also a shortcut for
3936 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3937
Georg Brandl62069d32010-07-31 08:56:11 +00003938- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3939 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003940
3941- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003942 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003943 like bytearray.
3944
Georg Brandl62069d32010-07-31 08:56:11 +00003945- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003946 used anymore and it was never documented.
3947
Georg Brandl62069d32010-07-31 08:56:11 +00003948- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003953- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3954 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3955 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3956 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003957
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003958- Issue #8748: Fix two issues with comparisons between complex and integer
3959 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003960 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3961 (2) The comparison raised an OverflowError for large integers, leading to
3962 unpredictable exceptions when combining integers and complex objects in sets
3963 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003964

3967
Victor Stinner9ca9c252010-05-19 16:53:30 +00003968- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003969 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003970 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003971
Georg Brandl62069d32010-07-31 08:56:11 +00003972- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3973 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003974
Victor Stinnerae6265f2010-05-15 16:27:27 +00003975- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3976 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003977 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003978 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003979
Victor Stinner59e62db2010-05-15 13:14:32 +00003980- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003981 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003982
Victor Stinnerb744ba12010-05-15 12:27:16 +00003983- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003984 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003985 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3986
Victor Stinner0964ee12010-04-30 16:48:45 +00003987- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003988 PyUnicode_FromString() to support surrogates in the filename and use the right
3989 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003990
Georg Brandl8569e582010-05-19 20:57:08 +00003991- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

3996 arguments.
3997
Victor Stinner14284c22010-04-23 12:02:30 +00003998- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003999 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00004005- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4006 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004007
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004008- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004009 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
4010 compared to the dynamic memory allocation fallback. Patch by Charles-François
4011 Natali.

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00004042- Issue #7845: Rich comparison methods on the complex type now return
4043 NotImplemented rather than raising a TypeError when comparing with an
4044 incompatible type; this allows user-defined classes to implement their own
4045 comparisons with complex.

Georg Brandl62069d32010-07-31 08:56:11 +00004093 where the right hand operand is a set of constants, by turning the set into a
4094 frozenset and pre-building it as a constant. The comparison operation is made
4095 against the constant instead of building a new set each time it is executed (a
4096 similar optimization already existed which turned a list of constants into a
4097 pre-built tuple). Patch and additional tests by Dave Malcolm.

4293 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4294 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004295 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004398- The default size of the re module's compiled regular expression cache has been
4399 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004400 simply clearing the entire cache on overflow to forgetting the least recently
4401 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004402 applications that use a lot of regular expressions and limits the impact of
4403 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004834- Comparisons using one of <, <=, >, >= between a complex instance and a
4835 Fractions instance now raise TypeError instead of returning True/False. This
4836 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4837 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005307- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
5308 digits in input, as recommended by the standard. Previously it was restricted
5309 to accepting [0-9].

Brett Cannon69194272009-07-20 04:23:48 +00005318- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00005319 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5320 PyPycLoader inherit from this class and provide implementations in relation to
5321 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005322
Brett Cannon64ef00f2009-07-20 03:19:18 +00005323- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5324 the documentation said it did even though the code in PyLoader relied on the
5325 abstract method required by ResourceLoader.
5326
Georg Brandl62069d32010-07-31 08:56:11 +00005327- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005380- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005381 compared to other unix systems. In particular, os.getgroups() does not reflect
5382 any changes made using os.setgroups() but basicly always returns the same
5383 information as the id command. os.getgroups() can now return more than 16
5384 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005409- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5410 Prior to this change, timezone adjustment in utctimetuple() could produce
5411 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5412 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005414- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5415 directive. When the ``%z`` directive is present in the format string, an
5416 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5417 ``datetime.timezone`` instance constructed from the parsed offset. If both
5418 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5419 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005421- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005422 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5423 ``datetime.timezone``, return fixed name and UTC offset from their
5424 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5425 returns ``None``. A class attribute, ``utc`` contains an instance
5426 representing the UTC timezone. Original patch by Rafe Kaplan.

5443 with an improved 'binary-split' algorithm that uses fewer multiplications and
5444 allows many of the multiplications to be performed using plain C integer
5445 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

5452 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005453 the result is now always correctly rounded, and is equivalent to ``td /
5454 timedelta(seconds=1)``.

5463 integer format code, struct.pack first attempts to convert the non-integer
5464 using its __index__ method. If that method is non-existent or raises
5465 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson865e01a2009-05-07 16:37:01 +00006032- Issue #5914: Add new C API function PyOS_string_to_double, and
6033 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6034
Eric Smith741191f2009-05-06 13:08:15 +00006035- Issue #3382: float.__format__, complex.__format__, and %-formatting
6036 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

6042
Eric Smith63376222009-05-05 14:04:18 +00006043- Issue #5920: For float.__format__, change the behavior with the
6044 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6045 to be like 'g' but with at least one decimal point and with a
6046 default precision of 12. Previously, the behavior the same but with
6047 a default precision of 6. This more closely matches str(), and
6048 reduces surprises when adding alignment flags to the empty
6049 presentation type. This also affects the new complex.__format__ in
6050 the same way.
6051
Martin v. Löwis011e8422009-05-05 04:43:17 +00006052- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00006063- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6064 received a new method, detach(). detach() disconnects the underlying stream
6065 from the buffer or text IO and returns it.
6066
Mark Dickinson33841c32009-05-01 15:37:04 +00006067- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6068 floats with absolute value over 1e50. Also remove length
6069 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6070 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00006072- Issue #1588: Add complex.__format__. For example,

Mark Dickinsone6a076d2009-04-18 11:48:33 +00006093- Issue #1869 (and many duplicates): make round(x, n) correctly
6094 rounded for a float x, by using the decimal <-> binary conversions
6095 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6096 consistently agrees with format(x, '.2f').
6097
Benjamin Petersonae937c02009-04-18 20:54:08 +00006098- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

6102
Eric Smith35e84722009-04-16 20:21:28 +00006103- Issue #5515: str.format() type 'n' combined with commas and leading
6104 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006105
6106- Implement PEP 378, Format Specifier for Thousands Separator, for
6107 floats.
6108
Mark Dickinson3370cce2009-04-17 22:40:53 +00006109- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006110 1e11, not 1e12. This avoids printing 13 significant digits in
6111 situations where only 12 of them are correct. Example problem
6112 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6113 long time.)
6114
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006115- Issue #1580: On most platforms, use a 'short' float repr: for a
6116 finite float x, repr(x) now outputs a string based on the shortest
6117 sequence of decimal digits that rounds to x. Previous behaviour was
6118 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006119 Another minor difference is that the new repr switches to
6120 exponential notation at 1e16 instead of the previous 1e17; this
6121 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006122
6123 There's a new sys attribute sys.float_repr_style, which takes
6124 the value 'short' to indicate that we're using short float repr,
6125 and 'legacy' if the short float repr isn't available for one
6126 reason or another.
6127
6128 The float repr change involves incorporating David Gay's 'perfect
6129 rounding' code into the Python core (it's in Python/dtoa.c). As a
6130 secondary consequence, all string-to-float and float-to-string
6131 conversions (including all float formatting operations) will be
6132 correctly rounded on these platforms.
6133
Georg Brandl5f90d792010-08-01 22:31:05 +00006134 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006135 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006137- Issue #5759: float() didn't call __float__ on str subclasses.
6138
Georg Brandlabc38772009-04-12 15:51:51 +00006139- The string.maketrans() function is deprecated; there is a new static method
6140 maketrans() on the bytes and bytearray classes. This removes confusion about
6141 the types string.maketrans() is supposed to work with, and mirrors the
6142 methods available on the str class.

6384 forever on incomplete input. That caused tarfile.open() to hang when used
6385 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6386 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00006407 struct.error instead of returning b'\xff\xff\xff\xff'. The
6408 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

6425 used when using str.format() with str, int, and float arguments.
6426
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006427- Issue #5249: time.strftime returned malformed string when format string
6428 contained non ascii character on windows.
6429
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006430- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6431 source has already been decoded into str.
6432
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006433- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6434 rotating the object pointer by 4 bits to the right.
6435
Mark Dickinson87ec0852009-02-09 17:15:59 +00006436- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6437 it now forces its argument to double before testing for infinity.
6438
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006439- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6440 returns a non-number type.
6441
Benjamin Peterson87618552009-02-08 15:00:52 +00006442- Issue #5182: Removed memoryview.__str__.
6443
Mark Dickinsonc008a172009-02-01 13:59:22 +00006444- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6445 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006446 the type definition cmpfunc. The tp_compare slot has been renamed
6447 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006448
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006449- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006450 were suppressing all exceptions. These include list() and bytearray().
6451
Mark Dickinson1124e712009-01-28 21:25:58 +00006452- Issue #4707: round(x, n) now returns an integer if x is an integer.
6453 Previously it returned a float.
6454
Antoine Pitroub52ec782009-01-25 16:34:23 +00006455- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6456 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6457 evaluation loop is compiled with a new dispatch mechanism which gives
6458 speedups of up to 20%, depending on the system, on various benchmarks.
6459
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006460- Issue #4874: Most builtin decoders now reject unicode input.

6466
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006467- Issue #4838: When a module is deallocated, free the memory backing the
6468 optional module state data.
6469
Mark Dickinson8055afd2009-01-17 10:04:45 +00006470- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006471 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006472
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006473- Issue #4935: The overflow checking code in the expandtabs() method common
6474 to str, bytes and bytearray could be optimized away by the compiler, letting
6475 the interpreter segfault instead of raising an error.
6476
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006477- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6478 __next__ method.
6479
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006480- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6481 function no longer attempt to call the __long__ slot to convert an object
6482 to an integer. Only the __int__ and __trunc__ slots are examined.
6483
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006484- Issue #4893: Use NT threading on CE.
6485
Martin v. Löwisec59d042009-01-12 07:59:10 +00006486- Issue #4915: Port sysmodule to Windows CE.
6487
Antoine Pitrouab868312009-01-10 15:40:25 +00006488- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6489 common cases are optimized thanks to a dedicated fast path and a moderate
6490 amount of loop unrolling.
6491
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006492- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6493 collecting the oldest generation) so that allocating lots of objects without
6494 destroying them does not show quadratic performance. Based on a proposal by
6495 Martin von Löwis at
6496 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6497
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006498- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006499 having been closed (for instance, a read() call could return some
6500 previously buffered data). Patch by Dmitry Vasiliev.
6501
Antoine Pitrou05608432009-01-09 18:53:14 +00006502- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6503 flag to work properly. Furthermore, when specifying -u, the text stdout
6504 and stderr streams have line-by-line buffering enabled (the default being
6505 to buffer arbitrary chunks of data).
6506
Raymond Hettinger35631532009-01-09 03:58:09 +00006507- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6508 instead of ints (reducing its size from 4 to 8 times thereby reducing
6509 Python's overall memory).
6510
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006511- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6512 an existing .py counterpart, override the co_filename attributes of all
6513 code objects if the original filename is obsolete (which can happen if the
6514 file has been renamed, moved, or if it is accessed through different paths).
6515 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6516
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006517- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6518 one byte. Also fixes the meaning of len() so that it returns the number of
6519 items, rather than the size in bytes.
6520
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006521- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6522
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006523- Issue #4747: When the terminal does not use utf-8, executing a script with
6524 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6525
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006526- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6527 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006528
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006529- Issue #3680: Reference cycles created through a dict, set or deque iterator
6530 did not get collected.
6531
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006532- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6533 where the tp_hash and tp_dict slots are both NULL.
6534
Georg Brandlccc47b62008-12-28 11:44:14 +00006535- Issue #4759: None is now allowed as the first argument of
6536 bytearray.translate(). It was always allowed for bytes.translate().
6537
Skip Montanaro80072cb2008-12-23 03:51:14 +00006538- Added test case to ensure attempts to read from a file opened for writing
6539 fail.
6540
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006541- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00006543- Issue #2183: Simplify and optimize bytecode for list, dict and set
6544 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6545
Antoine Pitrou621601a2008-12-17 23:18:19 +00006546- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6547 print elapsed times, not only when some objects are uncollectable /
6548 unreachable. Original patch by Neil Schemenauer.
6549
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006550- Issue #3439: Add a bit_length method to int.
6551
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006552- Issue #2173: When getting device encoding, check that return value of
6553 nl_langinfo is not the empty string. This was causing silent build
6554 failures on OS X.
6555
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006556- Issue #4597: Fixed several opcodes that weren't always propagating
6557 exceptions.
6558
6559- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006560 context manager returns a value that cannot be converted to a bool.
6561
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006562- Issue #4445: Replace "sizeof(PyBytesObject)" with
6563 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6564 bytes instances. On a typical machine this saves 3 bytes of memory
6565 (on average) per allocation of a bytes instance.
6566
Christian Heimesa872de52008-12-05 08:26:55 +00006567- Issue #4533: File read operation was dreadfully slow due to a slowly
6568 growing read buffer. Fixed by using the same growth rate algorithm as
6569 Python 2.x.
6570
Antoine Pitrou5504e892008-12-06 21:27:53 +00006571- Issue #4509: Various issues surrounding resize of bytearray objects to
6572 which there are buffer exports (e.g. memoryview instances).
6573
Georg Brandlf9734072008-12-07 15:30:06 +00006574- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6575 method on file objects with closefd=False. The file descriptor is still
6576 kept open but the file object behaves like a closed file. The ``FileIO``
6577 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006578
Antoine Pitroubc420402008-12-07 20:14:49 +00006579- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6580 larger than 1.

6585
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006586- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6587 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6588 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6589 of using the replace error handler in PyUnicode_DecodeUTF8().
