Ned Deily18fae3f2013-01-31 01:24:55 -0800828- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
829 In particular, fix extension module build failures when trying to use
830 32-bit-only installer Pythons on systems with Xcode 4 (currently
831 OS X 10.8, 10.7, and optionally 10.6).
832 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
833 * Since Xcode 4 removes ppc support, extension module builds now
834 check for ppc compiler support and by default remove ppc and
835 ppc64 archs when they are not available.
836 * Extension module builds now revert to using system installed
837 headers and libs (/usr and /System/Library) if the SDK used
838 to build the interpreter is not installed or has moved.
839 * Try to avoid building extension modules with deprecated
840 and problematic Apple llvm-gcc compiler. If original compiler
841 is not available, use clang instead by default.

Ned Deilyc47a4592012-02-11 20:40:24 +01001201 has left two versions of customize_compiler, the original in
1202 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001207- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1208 Distutils-based packages with C extension modules may fail because
1209 Apple has removed gcc-4.2, the version used to build python.org
1210 64-bit/32-bit Pythons. If the user does not explicitly override
1211 the default C compiler by setting the CC environment variable,
1212 Distutils will now attempt to compile extension modules with clang
1213 if gcc-4.2 is required but not found. Also as a convenience, if
1214 the user does explicitly set CC, substitute its value as the default
1215 compiler in the Distutils LDSHARED configuration variable for OS X.
1216 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1217 SDK, neither of which are available in Xcode 4. This change does not
1218 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001491- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1492 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1493 interpreter process. This could cause failures in non-Distutils subprocesses
1494 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001495 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001496 deployment target only in the environment of each build subprocess. It is
1497 still possible to globally override the default by setting
1498 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1499 greater or equal to the default value, the value with which the interpreter
1500 was built.

1527
Barry Warsawc5643282011-07-19 17:06:30 -04001528- sys.setcheckinterval() now updates the current ticker count as well as
1529 updating the check interval, so if the user decreases the check interval,
1530 the ticker doesn't have to wind down to zero from the old starting point
1531 before the new interval takes effect. And if the user increases the
1532 interval, it makes sure the new limit takes effect right away rather have an
1533 early task switch before recognizing the new interval.

2338
Victor Stinnercaafd772010-09-08 10:51:01 +00002339- Issue #4947: The write() method of sys.stdout and sys.stderr uses their

2357
2358 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2359 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2452 with invalid characters after '=' in a Q-encoded word.
2453

2455 received. Now sendall() properly calls signal handlers if necessary,

2468 handles non-blocking readinto() returning None correctly.
2469

2471 SSLSocket.sendto() to match the corresponding socket methods. Also,
2472 fix various SSLSocket methods to raise socket.error rather than an
2473 unhelpful TypeError when called on an unconnected socket. Original patch
2474 by Andrew Bennetts.
2475
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002476- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2477 values: d['x'] = d.
2478
Victor Stinner8fc843b2010-09-17 23:35:50 +00002479- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

2483
Raymond Hettinger20397532010-09-12 02:11:45 +00002484- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2485 This prevents user-created self-referencing ordered dictionaries from
2486 becoming permanently uncollectable GC garbage. The downside is that
2487 removing __del__ means that the internal doubly-linked list has to wait for
2488 GC collection rather than freeing memory immediately when the refcnt drops
2489 to zero.
2490
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002491- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002492 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002493 value.
2494
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002495- Issue #9792: In case of connection failure, socket.create_connection()
2496 would swallow the exception and raise a new one, making it impossible
2497 to fetch the original errno, or to filter timeout errors. Now the
2498 original error is re-raised.
2499
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002500- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2501 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2502 be updated back after the system call. Original patch by Brian Brazil.
2503
Antoine Pitroudca9de92010-09-04 17:52:26 +00002504- Issue #1100562: Fix deep-copying of objects derived from the list and

2508 ConfigParser.write.
2509
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002510- Issue #808164: Fixed socket.close to avoid references to globals, to
2511 avoid issues when socket.close is called from a __del__ method.
2512
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002513- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2514 can be set to False to turn off the previously undocumented 'popularity'
2515 heuristic. Patch by Terry Reedy and Eli Bendersky
2516
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002517- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2518 falling into recursion.
2519
R. David Murray7c4bf552010-08-25 01:45:57 +00002520- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2521 character years even if the message contains RFC822 two character years.
2522
Daniel Stutzbach91287322010-08-24 21:09:30 +00002523- Issue #8750: Fixed MutableSet's methods to correctly handle

2533
Raymond Hettinger917bba12010-08-22 08:01:58 +00002534- Issue #9214: Set operations on KeysView or ItemsView in the collections
2535 module now correctly return a set. (Patch by Eli Bendersky.)
2536
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002537- Issue #9617: Signals received during a low-level write operation aren't
2538 ignored by the buffered IO layer anymore.
2539
Benjamin Peterson52c36052010-08-21 03:03:22 +00002540- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2541 are not held onto after they are deleted elsewhere.
2542
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002543- Issue #9626: the view methods for collections.OrderedDict() were returning
2544 the unordered versions inherited from dict. Those methods are now
2545 overridden to provide ordered views.
2546

2549 without this marker will not be overwritten or removed.
2550
Antoine Pitroue1436d12010-08-12 15:25:51 +00002551- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2552 and a BadZipfile error is raised if it doesn't match (as used to be the
2553 case in Python 2.5 and earlier).
2554
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002555- Issue #9550: a BufferedReader could issue an additional read when the
2556 original read request had been satisfied, which could block indefinitely
2557 when the underlying raw IO channel was e.g. a socket. Report and original
2558 patch by Jason V. Miller.
2559
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002560- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002578- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2579 This is how it is supposed to work, wget and curl do the same. Previous
2580 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002948- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2949 start byte and the continuation byte(s) are now considered invalid, instead
2950 of the number of bytes specified by the start byte.
2951 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2952 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2953 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2954 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002962- Issue #8748: Fix two issues with comparisons between complex and integer
2963 objects. (1) The comparison could incorrectly return True in some cases
2964 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2965 (2) The comparison raised an OverflowError for large integers, leading

3350 with a non-empty format string. This is an effort to future-proof user
3351 code. If a derived class does not currently implement __format__ but later
3352 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003353 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003354 Python 3.3 and it will be an error in Python 3.4.

3386
Georg Brandlfee0f442010-05-22 21:26:21 +00003387- Issue #8257: The Decimal construct now accepts a float instance directly,
3388 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003389
3390 >>> Decimal(1.1)
3391 Decimal('1.100000000000000088817841970012523233890533447265625')
3392

Georg Brandlfee0f442010-05-22 21:26:21 +00003404- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3405 InvalidOperation instead of returning False. (Comparisons involving a quiet
3406 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3407 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003408
Georg Brandlfee0f442010-05-22 21:26:21 +00003409- Issue #2531: Comparison operations between floats and Decimal instances now
3410 return a result based on the numeric values of the operands; previously they
3411 returned an arbitrary result based on the relative ordering of id(float) and
3412 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003413
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003414- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003415 argument `-` which tells it to read files to compile from stdin. Each line is
3416 read on demand and the named file is compiled immediately. (Original patch by
3417 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003418
Georg Brandlfee0f442010-05-22 21:26:21 +00003419- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +00003426- Comparisons using one of <, <=, >, >= between a complex instance and a
3427 Fractions instance now raise TypeError instead of returning True/False. This
3428 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3429 <=> complex, and complex <=> complex comparisons.

3498 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3499 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003528- Issue #8300: When passing a non-integer argument to struct.pack with any
3529 integer format code, struct.pack first attempts to convert the non-integer
3530 using its __index__ method. If that method is non-existent or raises
3531 TypeError it goes on to try the __int__ method, as described below.
3532
Georg Brandlba83f822010-03-14 09:50:54 +00003533- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3534 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3535 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003536 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3537 inconsistent: __int__ was used for some integer codes but not for others, and
3538 the set of integer codes for which it was used differed between native packing
3539 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003846- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003847 file position when calling `truncate()`. It would previously change the file
3848 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003849 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3852 class used to represent files stored inside an archive. The new
3853 implementation is significantly faster and can be wrapped in a
3854 ``io.BufferedReader`` object for more speedups. It also solves an issue
3855 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003946- The ``__complex__()`` method is now looked up on the class of instances to
3947 make it consistent with other special methods.

3951
Mark Dickinson1b34d252010-01-01 17:27:30 +00003952- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003953 DeprecationWarning when passed a float argument where an integer was expected.
3954 These functions and methods now raise TypeError instead. The majority of the
3955 effects of this change are in the extension modules, but some core functions
3956 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3957 and many unicode/str methods.

3971 of integers: the result of a/b is now correctly rounded for ints a and b (at
3972 least on IEEE 754 platforms), and in particular does not depend on the
3973 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004122- Issue #3382: 'F' formatting for float and complex now convert the result to
4123 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4124 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004125
Georg Brandlba83f822010-03-14 09:50:54 +00004126- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4127 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004128
Georg Brandlba83f822010-03-14 09:50:54 +00004129- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4130 1e-100 used to raise OverflowError, but now gives the requested 120
4131 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004139
Georg Brandlba83f822010-03-14 09:50:54 +00004140- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4141 decimal string that's guaranteed to round back to x under correct rounding
4142 (with round-half-to-even rounding mode). Previously it gave a string based on
4143 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4144 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4145 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004146
Georg Brandlba83f822010-03-14 09:50:54 +00004147- Issue #7117: On almost all platforms: float-to-string and string-to-float
4148 conversions within Python are now correctly rounded. Places these conversions
4149 occur include: str for floats and complex numbers; the float and complex
4150 constructors; old-style and new-style numeric formatting; serialization and
4151 deserialization of floats and complex numbers using marshal, pickle and json;
4152 parsing of float and imaginary literals in Python code; Decimal-to-float
4153 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004154
Georg Brandlba83f822010-03-14 09:50:54 +00004155 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4156 providing correctly-rounded strtod and dtoa C functions. This code is
4157 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4158 the C compiler. There may be a small number of platforms on which correct
4159 operation of this code cannot be guaranteed, so the code is not used: notably,
4160 this applies to platforms where the C double format is not IEEE 754 binary64,
4161 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4162 and Python's configure script is unable to determine how to change the FPU
4163 precision. On these platforms conversions use the platform strtod and dtoa,
4164 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004165
Georg Brandlba83f822010-03-14 09:50:54 +00004166- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4167 uses the correctly-rounded string <-> float conversions described above (when
4168 available), and so produces correctly rounded results that will display nicely
4169 under the float repr. There are two related small changes: (1) round now
4170 accepts any class with an ``__index__()`` method for its second argument (but
4171 no longer accepts floats for the second argument), and (2) an excessively
4172 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4173 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004316 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4317 (2) parsing of strings representing infinities and nans was locale aware; and
4318 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004320- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4321 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4322 but with at least one decimal point and with a default precision
4323 of 12. Previously, the behavior the same but with a default precision of 6.
4324 This more closely matches ``str()``, and reduces surprises when adding
4325 alignment flags to the empty presentation type. This also affects the new
4326 complex.__format__ in the same way.
4327
4328- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4329 classtype's, even if it was None. property now inserts the __doc__ into the
4330 subclass instance __dict__.

4557 eventual KeyError would always report the empty ``frozenset()`` as the missing

Georg Brandlba83f822010-03-14 09:50:54 +00005812 leak-chasing test runs give sensible results. The previous method of reaping
5813 threads could return successfully while some Thread objects were still
5814 referenced. This also introduces a new private function: ``thread._count()``.

5936 exactly the recursion limit is exceeded. Consequently, both exception types
5937 are caught and silenced.

5953
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005954- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5955
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005956- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5957 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5958 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5959 ``printf`` function, whereas PyString_FromFormat has an independent
5960 implementation and uses "%zd" on all platforms for size_t values.
5961 This makes a difference on win64, where ``printf`` needs "%Id" to display
5962 64bit values.
5963
Benjamin Peterson97179b02008-09-09 20:55:01 +00005964- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5965 error.
5966
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005967- Issue #3777: long() applied to a float object now always return a long
5968 object; previously an int would be returned for small values. the __long__
5969 method is allowed to return either an int or a long, but the behaviour of
5970 float objects should not change to respect backward compatibility.
5971
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005972- Issue #3751: str.rpartition would perform a left-partition when called with
5973 a unicode argument.
5974
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005975- Issue #3683: Fix compilation when --without-threads is given.
5976
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005977- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005978 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005979 was correctly parsed but parsing of subsequent arguments failed.
5980
Vinay Sajip35e3b032008-09-01 14:33:59 +00005981- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005982 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5983 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5984 when given a tuple of classes as second argument, were looking up
5985 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5986 type object.
5987
Neal Norwitz18aa3882008-08-24 05:04:52 +00005988- Fix crashes on memory allocation failure found with failmalloc.
5989
5990- Fix memory leaks found with valgrind and update suppressions file.
5991
5992- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5993
5994- Fix problem using wrong name in decimal module reported by pychecker.
5995
Christian Heimes7d4c3172008-08-22 19:47:25 +00005996- Silenced another compiler warning about a used but not defined
5997 function 'stringlib_contains_obj'.
5998
Benjamin Peterson712ee922008-08-24 18:10:20 +00005999- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6000 ``__delslice__``.
6001
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006002- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6003 library targets in the Makefile.
6004
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006005- Issue #1204: The configure script now tests for additional libraries
6006 that may be required when linking against readline. This fixes issues
6007 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00006031 return a list or None rather than a custom object.
6032
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006033- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006057 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6058 for catch_warnings() also led to an improvement in the raising of a
6059 DeprecationWarning related to warnings.warn_explicit().
6060
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006061- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006125What's New in Python 2.6 beta 3?
6126================================
6127
Barry Warsaw07a4a382008-08-21 01:15:08 +00006128*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006129
6130Core and Builtins
6131-----------------
6132
Guido van Rossumf8402962008-08-20 15:01:50 +00006133- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6134 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6135 extensions do not automatically benefit from the class attribute
6136 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6137 to their tp_flags field if they care. This is a backwards
6138 compatibility feature; in 3.0, all types will use the cache by
6139 default.
6140
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006141- Keyword arguments can now follow starred arguments. (``f(a, *args,
6142 keyword=23)`` is now valid syntax.)
6143
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006144- ctypes function pointers that are COM methods have a boolean True
6145 value again.
6146
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006147- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6148 by denying s# to parse objects that have a releasebuffer procedure,
6149 and introducing s*.
6150
Georg Brandl1e13ea92008-08-11 09:07:59 +00006151- Issue #3537: Fix an assertion failure when an empty but presized dict
6152 object was stored in the freelist.
6153
Mark Dickinsonb6467572008-08-04 21:30:09 +00006154- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6155 ValueError consistently across platforms.
6156
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006157- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6158 (64bit Unix, for example), unichr() would truncate its argument and return
6159 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6160
Neal Norwitze7d8be82008-07-31 17:17:14 +00006161- Apply security patches from Apple.
6162
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006163- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6164 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6165
Antoine Pitrou92f82162008-07-25 22:22:08 +00006166- Issue #1819: function calls with several named parameters are now on
6167 average 35% faster (as measured by pybench).
6168
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006169- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6170 the python debugger steps into a class statement: the free variables (local
6171 variables defined in an outer scope) would be deleted from the outer scope.
6172
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006173- Issue #2620: Overflow checking when allocating or reallocating memory
6174 was not always being done properly in some python types and extension
6175 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6176 all been updated to perform better checks and places in the code that
6177 would previously leak memory on the error path when such an allocation
6178 failed have been fixed.

6184
Benjamin Petersone977ad42008-08-20 01:42:01 +00006185- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6186 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6187
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006188- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6189 version reported by these tools does not necessarily follow the python
6190 version numbering scheme, so the module is less strict when parsing it.
6191
Nick Coghlanf70385a2008-08-18 12:42:46 +00006192- Issue #2235: Added Py3k warnings for types which will become unhashable
6193 under the stricter __hash__ inheritance rules in 3.0. Several types
6194 which did not meet the rules for hash invariants and were already
6195 unhashable in 3.0 have now been explicitly flagged as unhashable in
6196 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6197 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6198
Brett Cannon88f801d2008-08-18 00:46:22 +00006199- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6200 imported into the module but exposed as part of the module's API.
6201
Brett Cannon7b96f072008-08-18 00:41:11 +00006202- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006206- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6207
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006208- Issue #3575: Incremental decoder's decode function now takes bytearray
6209 by using 's*' instead of 't#'.
6210
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006211- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006212 fails unicode conversion on 2nd parameter. (windows only)
6213
Georg Brandl222e2082010-08-01 22:27:39 +00006214- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00006268 asking for a specific length. This problem only affected files opened

6312
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006313- Issue #643841: The language reference now provides more detailed

6325-----------------
6326
Georg Brandl3e483f62008-07-16 22:57:41 +00006327- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6328 its methods now allow for items objects that can be converted to
6329 an integer using operator.index().
6330
Mark Dickinson64b7e502008-07-16 09:40:03 +00006331- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6332 produced a ValueError instead of giving the correct float.
6333
Eric Smitha5fa5a22008-07-16 00:11:49 +00006334- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6335 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6336
Mark Dickinson7103aa42008-07-15 19:08:33 +00006337- Issue #3008: the float type has a new instance method 'float.hex'
6338 and a new class method 'float.fromhex' to convert floating-point
6339 numbers to and from hexadecimal strings, respectively.
6340
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006341- Issue #2235: __hash__ is once again inherited by default. To allow
6342 collections.Hashable to remain meaningful in the presence of the
6343 default hash implementation (object.__hash__), it is now possible
6344 to explicit block inheritance of hash by setting __hash__=None at
6345 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6346 level.
6347
Nick Coghlanb028f502008-07-13 14:52:36 +00006348- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6349 the parent module cannot be found while performing an absolute import.
6350 This means that an incorrectly defined __package__ attribute will
6351 now only prevent relative imports in that module rather than causing
6352 all imports from that module to fail.
6353
Nick Coghlan14ff9942008-07-08 14:21:42 +00006354- Issue #2517: Allow unicode messages in Exceptions again by correctly

6364 another thread's dictionary.
6365
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006366- Issue #3004: Minor change to slice.indices(): the start and stop
6367 arguments are now treated identically, making the behaviour easier
6368 to describe and understand. For example, slice(None, -10,
6369 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6370 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6371 10, -1).
6372
Georg Brandl278fc502008-07-19 12:46:12 +00006373- Issue #3219: Calling a function with repeated keyword arguments,
6374 f(a=2, a=23), would not cause a syntax error. This was a regression
6375 from 2.4 caused by the switch to the new compiler.

6385 api functions without holding the GIL, which could lead to a fatal
6386 error when they failed.
6387
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006388- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006413- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6414 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006415 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006416 content-length. The problem had been corrected in the 2.4 branch, but never
6417 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006432- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6434
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006435- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6822
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006823- On MacOS X it is now possible to install the framework in 64-bit
6824 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006825 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006826
6827 This is controlled by the configure argument ``--with-universal-archs``:
6828
6829 - ``--with-universal-archs=all``: install 4-way universal
6830
6831 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6832
6833 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6834
6835 This option should be used in combination with ``--enable-universalsdk=``.
6836
6837 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006887- Issue #1631171: Re-implement the 'warnings' module in C (the
6888 original Python code has been kept as backup). This will allow for
6889 using the 'warning's machinery in such places as the parser where
6890 use of pure Python code is not possible. Both the ``showarning()``
6891 and ``formatwarning()`` gain an optional 'line' argument which is
6892 not called by default for backwards-compatibility reasons. Setting
6893 ``warnings.showwarning()`` to an implementation that lacks support
6894 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006936- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006937 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006957- Issue #2550: The approach used by client/server code for obtaining
6958 ports to listen on in network-oriented tests has been refined in an
6959 effort to facilitate running multiple instances of the entire
6960 regression test suite in parallel without issue.
6961 test_support.bind_port() has been fixed such that it will always
6962 return a unique port -- which wasn't always the case with the
6963 previous implementation, especially if socket options had been set
6964 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6965 new implementation of bind_port() will actually raise an exception
6966 if it is passed an AF_INET/SOCK_STREAM socket with either the
6967 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6968 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6969 the socket it's been passed. This currently only applies to
6970 Windows. This option prevents any other sockets from binding to the
6971 host/port we've bound to, thus removing the possibility of the
6972 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6973 when a second SOCK_STREAM socket binds and accepts to a host/port
6974 that's already been bound by another socket. The optional preferred
6975 port parameter to bind_port() has been removed. Under no
6976 circumstances should tests be hard coding ports!
6977
6978 test_support.find_unused_port() has also been introduced, which will
6979 pass a temporary socket object to bind_port() in order to obtain an
6980 unused port. The temporary socket object is then closed and
6981 deleted, and the port is returned. This method should only be used
6982 for obtaining an unused port in order to pass to an external program
6983 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6984 a parameter to a server-oriented class that doesn't give you direct
6985 access to the underlying socket used.
6986
6987 Finally, test_support.HOST has been introduced, which should be used
6988 for the host argument of any relevant socket calls (i.e. bind and
6989 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006990
6991 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006992 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006993 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6994 test_asynchat and test_socket_ssl.
6995
Georg Brandl3ee81df2008-05-17 18:14:43 +00006996 It is now possible for multiple instances of the regression test
6997 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007276- Added the future_builtins module, which contains hex() and oct().
7277 These are the PEP 3127 version of these functions, designed to be
7278 compatible with the hex() and oct() builtins from Python 3.0. They
7279 differ slightly in their output formats from the existing, unchanged
7280 Python 2.6 builtins. The expected usage of the future_builtins
7281 module is:
7282 from future_builtins import hex, oct
7283
Eric Smith7ef40bf2008-02-20 23:34:22 +00007284- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7285 exponents for exponents with absolute value < 100. Follows C99
7286 standard. This is a change on Windows, which would use 3 digits.
7287 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7288 so that any alterations it does to the resulting string will be
7289 available in stringlib/formatter.h (for float.__format__).
7290
Eric Smith5a3c1352008-02-19 13:21:56 +00007291- Implemented PEP 3101, Advanced String Formatting. This adds a new
7292 builtin format(); a format() method for str and unicode; a
7293 __format__() method to object, str, unicode, int, long, float, and
7294 datetime; the class string.Formatter; and the C API
7295 PyObject_Format().
7296
Georg Brandl3ee81df2008-05-17 18:14:43 +00007297- Fixed several potential crashes, all caused by specially crafted
7298 __del__ methods exploiting objects in temporarily inconsistent
7299 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007305- Fixed repr() and str() of complex numbers with infinity or nan as
7306 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007307
Georg Brandl3ee81df2008-05-17 18:14:43 +00007308- Clear all free lists during a gc.collect() of the highest generation
7309 in order to allow pymalloc to free more arenas. Python may give back
7310 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007311
Georg Brandl3ee81df2008-05-17 18:14:43 +00007312- Issue #2045: Fix an infinite recursion triggered when printing a
7313 subclass of collections.defaultdict, if its default_factory is set
7314 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007315
Christian Heimesf75dbef2008-02-08 00:11:31 +00007316- Fixed a minor memory leak in dictobject.c. The content of the free
7317 list was not freed on interpreter shutdown.
7318
Georg Brandl21e99f42010-03-07 15:23:59 +00007319- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007320 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007321
Georg Brandl3ee81df2008-05-17 18:14:43 +00007322- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7323 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007324 to compact the internal free lists of pre-allocted ints and floats.
7325
Georg Brandl3ee81df2008-05-17 18:14:43 +00007326- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7327 calls. Python expected the return type int but the fork familie
7328 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007329
Georg Brandl3ee81df2008-05-17 18:14:43 +00007330- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7331 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007332
Georg Brandl3ee81df2008-05-17 18:14:43 +00007333- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7334 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007335
Georg Brandl3ee81df2008-05-17 18:14:43 +00007336- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007339- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7340 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007341
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342- Patch #1473257: generator objects gain a gi_code attribute. This is
7343 the same object as the func_code attribute of the function that
7344 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007345
Georg Brandl3ee81df2008-05-17 18:14:43 +00007346- Issue #1920: "while 0" statements were completely removed by the
7347 compiler, even in the presence of an "else" clause, which is
7348 supposed to be run when the condition is false. Now the compiler
7349 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007350
Guido van Rossumeead05f2008-01-24 18:21:02 +00007351- A few crashers fixed: weakref_in_del.py (issue #1377858);
7352 loosing_dict_ref.py (issue #1303614, test67.py);
7353 borrowed_ref_[34].py (not in tracker).
7354
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007355- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007356 suppressed while an extension is loaded by calling SetErrorMode in
7357 dynload_win.c. The error is still reported properly.
7358
Georg Brandl3ee81df2008-05-17 18:14:43 +00007359- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007360 several extension methods and modules do not work without unicode
7361 support.
7362
Georg Brandl26543b12008-01-21 18:36:51 +00007363- Issue #1882: when compiling code from a string, encoding cookies in the
7364 second line of code were not always recognized correctly.
7365
Georg Brandl14404b62008-01-19 19:27:05 +00007366- Issue #1679: "0x" was taken as a valid integer literal.
7367
Georg Brandl6caad7d2008-01-26 14:19:22 +00007368- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007369 added.
7370
Christian Heimesc94e2b52008-01-14 04:13:37 +00007371- sys.float_info / PyFloat_GetInfo: The floating point information
7372 object was converted from a dict to a specialized structseq object.
7373
Georg Brandl3ee81df2008-05-17 18:14:43 +00007374- Patch #1816: Added sys.flags structseq. It exposes the status of
7375 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007376
Georg Brandl3ee81df2008-05-17 18:14:43 +00007377- Objects/structseq.c: Implemented new structseq representation. The
7378 patch makes structseqs (e.g. the return value of os.stat) more
7379 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007380
Georg Brandl3ee81df2008-05-17 18:14:43 +00007381- Patch #1700288: added a type attribute cache that caches method
7382 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007383
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007384- Bug #1776: __import__() no longer accepts filenames on any platform.
7385 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007386
Georg Brandlaed6c662008-01-07 17:25:53 +00007387- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7388
Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7390 envvar and sys.dont_write_bytecode attribute. All these can be set
7391 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007392
Georg Brandl3ee81df2008-05-17 18:14:43 +00007393- Improve some exception messages when Windows fails to load an
7394 extension module. Now we get for example '%1 is not a valid Win32
7395 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007396

7400 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007401
Christian Heimes0a8143f2007-12-18 23:22:54 +00007402- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403 and INF. float("nan"), float("inf") and float("-inf") now work on
7404 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007405
Georg Brandl3ee81df2008-05-17 18:14:43 +00007406- Compiler now generates simpler and faster code for dictionary
7407 literals. The oparg for BUILD_MAP now indicates an estimated
7408 dictionary size. There is a new opcode, STORE_MAP, for adding
7409 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Patch #1739468: Directories and zipfiles containing a __main__.py
7439 file can now be directly executed by passing their name to the
7440 interpreter. The directory/zipfile is automatically inserted as the
7441 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007442
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443- Issue #1265: Fix a problem with sys.settrace, if the tracing
7444 function uses a generator expression when at the same time the
7445 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007446
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007447- sets and frozensets now have an isdisjoint() method.
7448
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007449- optimize the performance of builtin.sum().
7450
Neal Norwitz44f326e2007-10-05 05:29:17 +00007451- Fix warnings found by the new version of the Coverity checker.
7452
Georg Brandl21e99f42010-03-07 15:23:59 +00007453- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7455 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007456
Georg Brandl3ee81df2008-05-17 18:14:43 +00007457- Issue #1686386: Tuple's tp_repr did not take into account the
7458 possibility of having a self-referential tuple, which is possible
7459 from C code. Nor did object's tp_str consider that a type's tp_str
7460 could do something that could lead to an inifinite recursion.
7461 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7462 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007463
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464- Issue #1164: It was possible to trigger deadlock when using the
7465 'print' statement to write to a file since the GIL was not released
7466 as needed. Now PyObject_Print() does the right thing along with
7467 various tp_print implementations of the built-in types and those in
7468 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007469
Georg Brandl3ee81df2008-05-17 18:14:43 +00007470- Issue #1147: Exceptions were directly allowing string exceptions in
7471 their throw() method even though string exceptions no longer
7472 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007473
Georg Brandl3ee81df2008-05-17 18:14:43 +00007474- Issue #1096: Prevent a segfault from getting the repr of a very
7475 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007476
Brett Cannon1e534b52007-09-07 04:18:30 +00007477- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007478 PyObject_Call() never calling back out to Python code to trigger
7479 recursion depth updates/checks. Required the creation of a static
7480 RuntimeError instance in case normalizing an exception put the
7481 recursion check value past its limit. Fixes crashers
7482 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007497- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007498 __*__ attributes. (Some already existed, e.g., __doc__ and
7499 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007501- Add -3 option to the interpreter to warn about features that are
7502 deprecated and will be changed/removed in Python 3.0.
7503
Georg Brandl2134e752007-05-21 20:34:16 +00007504- Patch #1686487: you can now pass any mapping after '**' in function
7505 calls.
7506
Collin Winter62903052007-05-18 23:11:24 +00007507- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007508 "except E as target:". This is to provide forwards compatibility
7509 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007511- Deprecate BaseException.message as per PEP 352.
7512
Georg Brandl3ee81df2008-05-17 18:14:43 +00007513- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007514 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007516- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007517 setting a plain string, ie don't expand to single letter identifiers.
7518
Raymond Hettinger13936692007-04-11 18:40:58 +00007519- Request #1191699: Slices can now be pickled.
7520
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007521- Request #1193128: str.translate() now allows a None argument for
7522 translations that only remove characters without re-mapping the
7523 remaining characters.
7524
Georg Brandl5cb76c12007-03-21 09:00:39 +00007525- Patch #1682205: a TypeError while unpacking an iterable is no longer
7526 masked by a generic one with the message "unpack non-sequence".
7527
Neal Norwitzaa754b72007-03-21 06:39:48 +00007528- Remove unused file Python/fmod.c.
7529
Guido van Rossum143b5642007-03-23 04:58:42 +00007530- Bug #1683368: The object.__init__() and object.__new__() methods are
7531 now stricter in rejecting excess arguments. The only time when
7532 either allows excess arguments is when it is not overridden and the
7533 other one is. For backwards compatibility, when both are
7534 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007535 warning later). Also, type.__init__() insists on the same signature
7536 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007538- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7539 object to complex using its __complex__() method before falling back
7540 to the __float__() method. Therefore, the functions in the cmath
7541 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008514 that the SMTP.starttls() caller no longer needs to call ehlo()
8515 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008516 does not claim to support starttls. Adds the
8517 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8518 Fenner.

8598 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8599 silently miscode subclasses of those types. Now, it raises a
8600 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008601

Georg Brandl3ee81df2008-05-17 18:14:43 +00008616 time so that opening a database previously created with the DB_DUP
8617 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8618 opens. Specifically: dictionary assignment to a DB object will
8619 replace all values for a given key when the database allows
8620 duplicate values. DB users should use DB.put(k, v) when they want
8621 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008622

8628 characters with ASCII value less than 32. Also, it correctly quotes
8629 dots only if they occur on a single line, as opposed to the previous
8630 behavior of quoting dots if they are the second character of any
8631 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008632
