826 In particular, fix extension module build failures when trying to use
827 32-bit-only installer Pythons on systems with Xcode 4 (currently
828 OS X 10.8, 10.7, and optionally 10.6).
829 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
830 * Since Xcode 4 removes ppc support, extension module builds now
831 check for ppc compiler support and by default remove ppc and
832 ppc64 archs when they are not available.
833 * Extension module builds now revert to using system installed
834 headers and libs (/usr and /System/Library) if the SDK used
835 to build the interpreter is not installed or has moved.
836 * Try to avoid building extension modules with deprecated
837 and problematic Apple llvm-gcc compiler. If original compiler
838 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001195- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001196 has left two versions of customize_compiler, the original in
1197 distutils.sysconfig and another copy in distutils.ccompiler, with some
1198 parts of distutils calling one and others using the other.

1200 is the case in 3.x.
1201
Ned Deily0d0ea482012-02-10 12:59:06 +01001202- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1203 Distutils-based packages with C extension modules may fail because
1204 Apple has removed gcc-4.2, the version used to build python.org
1205 64-bit/32-bit Pythons. If the user does not explicitly override
1206 the default C compiler by setting the CC environment variable,
1207 Distutils will now attempt to compile extension modules with clang
1208 if gcc-4.2 is required but not found. Also as a convenience, if
1209 the user does explicitly set CC, substitute its value as the default
1210 compiler in the Distutils LDSHARED configuration variable for OS X.
1211 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1212 SDK, neither of which are available in Xcode 4. This change does not
1213 attempt to override settings to support their use with Xcode 4.)

1298 raised when the wrapped raw file is non-blocking and the write would block.

Ned Deily87e82bb2011-06-28 19:52:59 -07001486- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1487 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1488 interpreter process. This could cause failures in non-Distutils subprocesses
1489 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001490 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001491 deployment target only in the environment of each build subprocess. It is
1492 still possible to globally override the default by setting
1493 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1494 greater or equal to the default value, the value with which the interpreter
1495 was built.

1525 the ticker doesn't have to wind down to zero from the old starting point
1526 before the new interval takes effect. And if the user increases the
1527 interval, it makes sure the new limit takes effect right away rather have an
1528 early task switch before recognizing the new interval.

2332 thread-local storage key.
2333
Victor Stinnercaafd772010-09-08 10:51:01 +00002334- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2335 encoding and errors attributes instead of using utf-8 in strict mode, to get
2336 the same behaviour than the print statement.
2337
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002338- Issue #9737: Fix a crash when trying to delete a slice or an item from

2352
2353 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2354 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2448

2450 received. Now sendall() properly calls signal handlers if necessary,
2451 and retries sending if these returned successfully, including on sockets

2463 handles non-blocking readinto() returning None correctly.

2466 SSLSocket.sendto() to match the corresponding socket methods. Also,
2467 fix various SSLSocket methods to raise socket.error rather than an
2468 unhelpful TypeError when called on an unconnected socket. Original patch
2469 by Andrew Bennetts.
2470
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002471- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2472 values: d['x'] = d.

2478
Raymond Hettinger20397532010-09-12 02:11:45 +00002479- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2480 This prevents user-created self-referencing ordered dictionaries from
2481 becoming permanently uncollectable GC garbage. The downside is that
2482 removing __del__ means that the internal doubly-linked list has to wait for
2483 GC collection rather than freeing memory immediately when the refcnt drops
2484 to zero.
2485
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002486- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002487 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002488 value.
2489
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002490- Issue #9792: In case of connection failure, socket.create_connection()
2491 would swallow the exception and raise a new one, making it impossible
2492 to fetch the original errno, or to filter timeout errors. Now the
2493 original error is re-raised.
2494
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002495- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2496 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2497 be updated back after the system call. Original patch by Brian Brazil.
2498
Antoine Pitroudca9de92010-09-04 17:52:26 +00002499- Issue #1100562: Fix deep-copying of objects derived from the list and

2503 ConfigParser.write.
2504
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002505- Issue #808164: Fixed socket.close to avoid references to globals, to
2506 avoid issues when socket.close is called from a __del__ method.
2507
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002508- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2509 can be set to False to turn off the previously undocumented 'popularity'
2510 heuristic. Patch by Terry Reedy and Eli Bendersky
2511
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002512- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2513 falling into recursion.
2514
R. David Murray7c4bf552010-08-25 01:45:57 +00002515- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2516 character years even if the message contains RFC822 two character years.
2517
Daniel Stutzbach91287322010-08-24 21:09:30 +00002518- Issue #8750: Fixed MutableSet's methods to correctly handle

2528
Raymond Hettinger917bba12010-08-22 08:01:58 +00002529- Issue #9214: Set operations on KeysView or ItemsView in the collections
2530 module now correctly return a set. (Patch by Eli Bendersky.)
2531
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002532- Issue #9617: Signals received during a low-level write operation aren't
2533 ignored by the buffered IO layer anymore.
2534
Benjamin Peterson52c36052010-08-21 03:03:22 +00002535- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2536 are not held onto after they are deleted elsewhere.
2537
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002538- Issue #9626: the view methods for collections.OrderedDict() were returning
2539 the unordered versions inherited from dict. Those methods are now
2540 overridden to provide ordered views.

2544 without this marker will not be overwritten or removed.
2545
Antoine Pitroue1436d12010-08-12 15:25:51 +00002546- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2547 and a BadZipfile error is raised if it doesn't match (as used to be the
2548 case in Python 2.5 and earlier).
2549
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002550- Issue #9550: a BufferedReader could issue an additional read when the
2551 original read request had been satisfied, which could block indefinitely
2552 when the underlying raw IO channel was e.g. a socket. Report and original
2553 patch by Jason V. Miller.
2554
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002555- Issue #9551: Don't raise TypeError when setting the value to None for

2571 PROT_WRITE and PROT_EXEC.
2572
Senthil Kumarane677ecf2010-08-08 11:56:31 +00002573- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2574 This is how it is supposed to work, wget and curl do the same. Previous
2575 behavior was wrong.
2576
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00002577- Issue #2944: asyncore doesn't handle connection refused correctly.

2942
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002943- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2944 start byte and the continuation byte(s) are now considered invalid, instead
2945 of the number of bytes specified by the start byte.
2946 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2947 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2948 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2949 Previous versions returned a single u'\ufffd'.

Mark Dickinsone4b83e02010-06-05 12:14:43 +00002952 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2953 arises from the "Overriding __eq__ blocks inheritance ..." warning
2954 when turned into an exception: in this case the exception simply
2955 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002956
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002957- Issue #8748: Fix two issues with comparisons between complex and integer
2958 objects. (1) The comparison could incorrectly return True in some cases
2959 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2960 (2) The comparison raised an OverflowError for large integers, leading
2961 to unpredictable exceptions when combining integers and complex objects
2962 in sets or dicts.
2963
Mark Dickinson81336372010-05-30 12:12:25 +00002964- Issue #5211: Implicit coercion for the complex type is now completely
2965 removed. (Coercion for arithmetic operations was already removed in 2.7
2966 alpha 4, but coercion for rich comparisons was accidentally left in.)
2967
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002968- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2969 and error handler, instead of writing to the C stderr file in utf-8
2970
Georg Brandlfee0f442010-05-22 21:26:21 +00002971- Issue #7902: When using explicit relative import syntax, don't try implicit
2972 relative import semantics.

2975 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00002977- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00002978 Window Server again in a framework build on MacOSX 10.5 or earlier.

2984 of the interpreter to set sys.argv without also modifying sys.path. This

Georg Brandlfee0f442010-05-22 21:26:21 +00003155- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3156 operation raises multiple signals and more than one of those signals is
3157 trapped, the specification determines the order in which the signals should be
3158 handled. In many cases this order wasn't being followed, leading to the wrong

3345 with a non-empty format string. This is an effort to future-proof user
3346 code. If a derived class does not currently implement __format__ but later
3347 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003348 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003349 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003382- Issue #8257: The Decimal construct now accepts a float instance directly,
3383 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003384
3385 >>> Decimal(1.1)
3386 Decimal('1.100000000000000088817841970012523233890533447265625')
3387

Georg Brandlfee0f442010-05-22 21:26:21 +00003399- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3400 InvalidOperation instead of returning False. (Comparisons involving a quiet
3401 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3402 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003403
Georg Brandlfee0f442010-05-22 21:26:21 +00003404- Issue #2531: Comparison operations between floats and Decimal instances now
3405 return a result based on the numeric values of the operands; previously they
3406 returned an arbitrary result based on the relative ordering of id(float) and
3407 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003409- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003410 argument `-` which tells it to read files to compile from stdin. Each line is
3411 read on demand and the named file is compiled immediately. (Original patch by
3412 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00003421- Comparisons using one of <, <=, >, >= between a complex instance and a
3422 Fractions instance now raise TypeError instead of returning True/False. This
3423 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3424 <=> complex, and complex <=> complex comparisons.

3524 integer format code, struct.pack first attempts to convert the non-integer

3527
Georg Brandlba83f822010-03-14 09:50:54 +00003528- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3529 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3530 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003531 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3532 inconsistent: __int__ was used for some integer codes but not for others, and
3533 the set of integer codes for which it was used differed between native packing
3534 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003842 file position when calling `truncate()`. It would previously change the file
3843 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003844 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003846- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3847 class used to represent files stored inside an archive. The new
3848 implementation is significantly faster and can be wrapped in a
3849 ``io.BufferedReader`` object for more speedups. It also solves an issue
3850 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3863 encoded string for them. This ensures that the upload and register commands
3864 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003941- The ``__complex__()`` method is now looked up on the class of instances to
3942 make it consistent with other special methods.

3946
Mark Dickinson1b34d252010-01-01 17:27:30 +00003947- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003948 DeprecationWarning when passed a float argument where an integer was expected.
3949 These functions and methods now raise TypeError instead. The majority of the
3950 effects of this change are in the extension modules, but some core functions
3951 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3952 and many unicode/str methods.

3966 of integers: the result of a/b is now correctly rounded for ints a and b (at
3967 least on IEEE 754 platforms), and in particular does not depend on the
3968 internal representation of a long.

3976
Georg Brandlba83f822010-03-14 09:50:54 +00003977 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004114- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4115 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004116
Georg Brandlba83f822010-03-14 09:50:54 +00004117- Issue #3382: 'F' formatting for float and complex now convert the result to
4118 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4119 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004120
Georg Brandlba83f822010-03-14 09:50:54 +00004121- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4122 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004123
Georg Brandlba83f822010-03-14 09:50:54 +00004124- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4125 1e-100 used to raise OverflowError, but now gives the requested 120
4126 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004127
Georg Brandlba83f822010-03-14 09:50:54 +00004128- Add Py3k warnings for parameter names in parentheses.

4133 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004134
Georg Brandlba83f822010-03-14 09:50:54 +00004135- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4136 decimal string that's guaranteed to round back to x under correct rounding
4137 (with round-half-to-even rounding mode). Previously it gave a string based on
4138 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4139 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4140 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004141
Georg Brandlba83f822010-03-14 09:50:54 +00004142- Issue #7117: On almost all platforms: float-to-string and string-to-float
4143 conversions within Python are now correctly rounded. Places these conversions
4144 occur include: str for floats and complex numbers; the float and complex
4145 constructors; old-style and new-style numeric formatting; serialization and
4146 deserialization of floats and complex numbers using marshal, pickle and json;
4147 parsing of float and imaginary literals in Python code; Decimal-to-float
4148 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004149
Georg Brandlba83f822010-03-14 09:50:54 +00004150 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4151 providing correctly-rounded strtod and dtoa C functions. This code is
4152 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4153 the C compiler. There may be a small number of platforms on which correct
4154 operation of this code cannot be guaranteed, so the code is not used: notably,
4155 this applies to platforms where the C double format is not IEEE 754 binary64,
4156 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4157 and Python's configure script is unable to determine how to change the FPU
4158 precision. On these platforms conversions use the platform strtod and dtoa,
4159 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004160
Georg Brandlba83f822010-03-14 09:50:54 +00004161- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4162 uses the correctly-rounded string <-> float conversions described above (when
4163 available), and so produces correctly rounded results that will display nicely
4164 under the float repr. There are two related small changes: (1) round now
4165 accepts any class with an ``__index__()`` method for its second argument (but
4166 no longer accepts floats for the second argument), and (2) an excessively
4167 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4168 raises an exception.

4171
Georg Brandlba83f822010-03-14 09:50:54 +00004172- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00004315- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4316 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4317 but with at least one decimal point and with a default precision
4318 of 12. Previously, the behavior the same but with a default precision of 6.
4319 This more closely matches ``str()``, and reduces surprises when adding
4320 alignment flags to the empty presentation type. This also affects the new
4321 complex.__format__ in the same way.
4322
4323- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4324 classtype's, even if it was None. property now inserts the __doc__ into the
4325 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00004545- On windows, ``os.chdir()`` given unicode was not working if

4547 this code path is really executed because I cannot move to such directory on
4548 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004550- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4551 element is temporarily replaced with an equivalent frozenset. But the
4552 eventual KeyError would always report the empty ``frozenset()`` as the missing
4553 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00005807 leak-chasing test runs give sensible results. The previous method of reaping
5808 threads could return successfully while some Thread objects were still
5809 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005810
Georg Brandlba83f822010-03-14 09:50:54 +00005811- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

5948
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005949- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5950
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005951- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5952 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5953 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5954 ``printf`` function, whereas PyString_FromFormat has an independent
5955 implementation and uses "%zd" on all platforms for size_t values.
5956 This makes a difference on win64, where ``printf`` needs "%Id" to display
5957 64bit values.
5958
Benjamin Peterson97179b02008-09-09 20:55:01 +00005959- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5960 error.
5961
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005962- Issue #3777: long() applied to a float object now always return a long
5963 object; previously an int would be returned for small values. the __long__
5964 method is allowed to return either an int or a long, but the behaviour of
5965 float objects should not change to respect backward compatibility.
5966
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005967- Issue #3751: str.rpartition would perform a left-partition when called with
5968 a unicode argument.
5969
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005970- Issue #3683: Fix compilation when --without-threads is given.
5971
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005972- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005973 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005974 was correctly parsed but parsing of subsequent arguments failed.
5975
Vinay Sajip35e3b032008-09-01 14:33:59 +00005976- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005977 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5978 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5979 when given a tuple of classes as second argument, were looking up
5980 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5981 type object.
5982
Neal Norwitz18aa3882008-08-24 05:04:52 +00005983- Fix crashes on memory allocation failure found with failmalloc.
5984
5985- Fix memory leaks found with valgrind and update suppressions file.
5986
5987- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5988
5989- Fix problem using wrong name in decimal module reported by pychecker.
5990
Christian Heimes7d4c3172008-08-22 19:47:25 +00005991- Silenced another compiler warning about a used but not defined
5992 function 'stringlib_contains_obj'.
5993
Benjamin Peterson712ee922008-08-24 18:10:20 +00005994- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5995 ``__delslice__``.
5996
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005997- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5998 library targets in the Makefile.
5999
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006000- Issue #1204: The configure script now tests for additional libraries
6001 that may be required when linking against readline. This fixes issues
6002 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006052 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6053 for catch_warnings() also led to an improvement in the raising of a
6054 DeprecationWarning related to warnings.warn_explicit().
6055
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006056- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006120What's New in Python 2.6 beta 3?
6121================================
6122
Barry Warsaw07a4a382008-08-21 01:15:08 +00006123*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006124
6125Core and Builtins
6126-----------------
6127
Guido van Rossumf8402962008-08-20 15:01:50 +00006128- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6129 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6130 extensions do not automatically benefit from the class attribute
6131 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6132 to their tp_flags field if they care. This is a backwards
6133 compatibility feature; in 3.0, all types will use the cache by
6134 default.
6135
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006136- Keyword arguments can now follow starred arguments. (``f(a, *args,
6137 keyword=23)`` is now valid syntax.)
6138
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006139- ctypes function pointers that are COM methods have a boolean True
6140 value again.
6141
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006142- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6143 by denying s# to parse objects that have a releasebuffer procedure,
6144 and introducing s*.
6145
Georg Brandl1e13ea92008-08-11 09:07:59 +00006146- Issue #3537: Fix an assertion failure when an empty but presized dict
6147 object was stored in the freelist.
6148
Mark Dickinsonb6467572008-08-04 21:30:09 +00006149- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6150 ValueError consistently across platforms.
6151
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006152- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6153 (64bit Unix, for example), unichr() would truncate its argument and return
6154 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6155
Neal Norwitze7d8be82008-07-31 17:17:14 +00006156- Apply security patches from Apple.
6157
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006158- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6159 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6160
Antoine Pitrou92f82162008-07-25 22:22:08 +00006161- Issue #1819: function calls with several named parameters are now on
6162 average 35% faster (as measured by pybench).
6163
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006164- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6165 the python debugger steps into a class statement: the free variables (local
6166 variables defined in an outer scope) would be deleted from the outer scope.
6167
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006168- Issue #2620: Overflow checking when allocating or reallocating memory
6169 was not always being done properly in some python types and extension
6170 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6171 all been updated to perform better checks and places in the code that
6172 would previously leak memory on the error path when such an allocation
6173 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00006180- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6181 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6182
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006183- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6184 version reported by these tools does not necessarily follow the python
6185 version numbering scheme, so the module is less strict when parsing it.
6186
Nick Coghlanf70385a2008-08-18 12:42:46 +00006187- Issue #2235: Added Py3k warnings for types which will become unhashable
6188 under the stricter __hash__ inheritance rules in 3.0. Several types
6189 which did not meet the rules for hash invariants and were already
6190 unhashable in 3.0 have now been explicitly flagged as unhashable in
6191 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6192 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6193
Brett Cannon88f801d2008-08-18 00:46:22 +00006194- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6202
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006203- Issue #3575: Incremental decoder's decode function now takes bytearray
6204 by using 's*' instead of 't#'.
6205
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006206- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006207 fails unicode conversion on 2nd parameter. (windows only)
6208
Georg Brandl222e2082010-08-01 22:27:39 +00006209- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00006263 asking for a specific length. This problem only affected files opened

6307
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006308- Issue #643841: The language reference now provides more detailed

6320-----------------
6321
Georg Brandl3e483f62008-07-16 22:57:41 +00006322- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6323 its methods now allow for items objects that can be converted to
6324 an integer using operator.index().
6325
Mark Dickinson64b7e502008-07-16 09:40:03 +00006326- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6327 produced a ValueError instead of giving the correct float.
6328
Eric Smitha5fa5a22008-07-16 00:11:49 +00006329- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6330 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6331
Mark Dickinson7103aa42008-07-15 19:08:33 +00006332- Issue #3008: the float type has a new instance method 'float.hex'
6333 and a new class method 'float.fromhex' to convert floating-point
6334 numbers to and from hexadecimal strings, respectively.
6335
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006336- Issue #2235: __hash__ is once again inherited by default. To allow
6337 collections.Hashable to remain meaningful in the presence of the
6338 default hash implementation (object.__hash__), it is now possible
6339 to explicit block inheritance of hash by setting __hash__=None at
6340 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6341 level.
6342
Nick Coghlanb028f502008-07-13 14:52:36 +00006343- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6344 the parent module cannot be found while performing an absolute import.
6345 This means that an incorrectly defined __package__ attribute will
6346 now only prevent relative imports in that module rather than causing
6347 all imports from that module to fail.
6348
Nick Coghlan14ff9942008-07-08 14:21:42 +00006349- Issue #2517: Allow unicode messages in Exceptions again by correctly
6350 bypassing the instance dictionary when looking up __unicode__ on
6351 new-style classes.

6359 another thread's dictionary.
6360
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006361- Issue #3004: Minor change to slice.indices(): the start and stop
6362 arguments are now treated identically, making the behaviour easier
6363 to describe and understand. For example, slice(None, -10,
6364 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6365 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6366 10, -1).
6367
Georg Brandl278fc502008-07-19 12:46:12 +00006368- Issue #3219: Calling a function with repeated keyword arguments,
6369 f(a=2, a=23), would not cause a syntax error. This was a regression
6370 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00006372- Issue #2862: Make int and float freelist management consistent with
6373 other freelists. Changes their CompactFreeList apis into

6380 api functions without holding the GIL, which could lead to a fatal
6381 error when they failed.
6382
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006383- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006408- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6409 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006410 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006411 content-length. The problem had been corrected in the 2.4 branch, but never
6412 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006427- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6429
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006430- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6815
Brett Cannonb61d8012008-05-11 23:39:04 +00006816- ``Lib/lib-old`` is now added to sys.path.
6817
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006818- On MacOS X it is now possible to install the framework in 64-bit
6819 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006820 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006821
6822 This is controlled by the configure argument ``--with-universal-archs``:
6823
6824 - ``--with-universal-archs=all``: install 4-way universal
6825
6826 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6827
6828 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6829
6830 This option should be used in combination with ``--enable-universalsdk=``.
6831
6832 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 +00006882- Issue #1631171: Re-implement the 'warnings' module in C (the
6883 original Python code has been kept as backup). This will allow for
6884 using the 'warning's machinery in such places as the parser where
6885 use of pure Python code is not possible. Both the ``showarning()``
6886 and ``formatwarning()`` gain an optional 'line' argument which is
6887 not called by default for backwards-compatibility reasons. Setting
6888 ``warnings.showwarning()`` to an implementation that lacks support
6889 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006914- The getpass module has been improved on Unix. It now uses /dev/tty
6915 by default and uses stderr instead of stdout. A GetPassWarning is
6916 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006931- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006932 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006952- Issue #2550: The approach used by client/server code for obtaining
6953 ports to listen on in network-oriented tests has been refined in an
6954 effort to facilitate running multiple instances of the entire
6955 regression test suite in parallel without issue.
6956 test_support.bind_port() has been fixed such that it will always
6957 return a unique port -- which wasn't always the case with the
6958 previous implementation, especially if socket options had been set
6959 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6960 new implementation of bind_port() will actually raise an exception
6961 if it is passed an AF_INET/SOCK_STREAM socket with either the
6962 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6963 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6964 the socket it's been passed. This currently only applies to
6965 Windows. This option prevents any other sockets from binding to the
6966 host/port we've bound to, thus removing the possibility of the
6967 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6968 when a second SOCK_STREAM socket binds and accepts to a host/port
6969 that's already been bound by another socket. The optional preferred
6970 port parameter to bind_port() has been removed. Under no
6971 circumstances should tests be hard coding ports!
6972
6973 test_support.find_unused_port() has also been introduced, which will
6974 pass a temporary socket object to bind_port() in order to obtain an
6975 unused port. The temporary socket object is then closed and
6976 deleted, and the port is returned. This method should only be used
6977 for obtaining an unused port in order to pass to an external program
6978 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6979 a parameter to a server-oriented class that doesn't give you direct
6980 access to the underlying socket used.
6981
6982 Finally, test_support.HOST has been introduced, which should be used
6983 for the host argument of any relevant socket calls (i.e. bind and
6984 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006985
6986 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006987 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006988 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6989 test_asynchat and test_socket_ssl.
6990
Georg Brandl3ee81df2008-05-17 18:14:43 +00006991 It is now possible for multiple instances of the regression test
6992 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007271- Added the future_builtins module, which contains hex() and oct().
7272 These are the PEP 3127 version of these functions, designed to be
7273 compatible with the hex() and oct() builtins from Python 3.0. They
7274 differ slightly in their output formats from the existing, unchanged
7275 Python 2.6 builtins. The expected usage of the future_builtins
7276 module is:
7277 from future_builtins import hex, oct
7278
Eric Smith7ef40bf2008-02-20 23:34:22 +00007279- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7280 exponents for exponents with absolute value < 100. Follows C99
7281 standard. This is a change on Windows, which would use 3 digits.
7282 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7283 so that any alterations it does to the resulting string will be
7284 available in stringlib/formatter.h (for float.__format__).
7285
Eric Smith5a3c1352008-02-19 13:21:56 +00007286- Implemented PEP 3101, Advanced String Formatting. This adds a new
7287 builtin format(); a format() method for str and unicode; a
7288 __format__() method to object, str, unicode, int, long, float, and
7289 datetime; the class string.Formatter; and the C API
7290 PyObject_Format().
7291
Georg Brandl3ee81df2008-05-17 18:14:43 +00007292- Fixed several potential crashes, all caused by specially crafted
7293 __del__ methods exploiting objects in temporarily inconsistent
7294 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007300- Fixed repr() and str() of complex numbers with infinity or nan as
7301 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007302
Georg Brandl3ee81df2008-05-17 18:14:43 +00007303- Clear all free lists during a gc.collect() of the highest generation
7304 in order to allow pymalloc to free more arenas. Python may give back
7305 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007306
Georg Brandl3ee81df2008-05-17 18:14:43 +00007307- Issue #2045: Fix an infinite recursion triggered when printing a
7308 subclass of collections.defaultdict, if its default_factory is set
7309 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007310
Christian Heimesf75dbef2008-02-08 00:11:31 +00007311- Fixed a minor memory leak in dictobject.c. The content of the free
7312 list was not freed on interpreter shutdown.
7313
Georg Brandl21e99f42010-03-07 15:23:59 +00007314- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007315 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007316
Georg Brandl3ee81df2008-05-17 18:14:43 +00007317- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7318 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007319 to compact the internal free lists of pre-allocted ints and floats.
7320
Georg Brandl3ee81df2008-05-17 18:14:43 +00007321- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7322 calls. Python expected the return type int but the fork familie
7323 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007324
Georg Brandl3ee81df2008-05-17 18:14:43 +00007325- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7326 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007327
Georg Brandl3ee81df2008-05-17 18:14:43 +00007328- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7329 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007330
Georg Brandl3ee81df2008-05-17 18:14:43 +00007331- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7332 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00007334- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7335 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007336
Georg Brandl3ee81df2008-05-17 18:14:43 +00007337- Patch #1473257: generator objects gain a gi_code attribute. This is
7338 the same object as the func_code attribute of the function that
7339 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007340
Georg Brandl3ee81df2008-05-17 18:14:43 +00007341- Issue #1920: "while 0" statements were completely removed by the
7342 compiler, even in the presence of an "else" clause, which is
7343 supposed to be run when the condition is false. Now the compiler
7344 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007345
Guido van Rossumeead05f2008-01-24 18:21:02 +00007346- A few crashers fixed: weakref_in_del.py (issue #1377858);
7347 loosing_dict_ref.py (issue #1303614, test67.py);
7348 borrowed_ref_[34].py (not in tracker).
7349
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007350- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007351 suppressed while an extension is loaded by calling SetErrorMode in
7352 dynload_win.c. The error is still reported properly.
7353
Georg Brandl3ee81df2008-05-17 18:14:43 +00007354- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007355 several extension methods and modules do not work without unicode
7356 support.
7357
Georg Brandl26543b12008-01-21 18:36:51 +00007358- Issue #1882: when compiling code from a string, encoding cookies in the
7359 second line of code were not always recognized correctly.
7360
Georg Brandl14404b62008-01-19 19:27:05 +00007361- Issue #1679: "0x" was taken as a valid integer literal.
7362
Georg Brandl6caad7d2008-01-26 14:19:22 +00007363- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007364 added.
7365
Christian Heimesc94e2b52008-01-14 04:13:37 +00007366- sys.float_info / PyFloat_GetInfo: The floating point information
7367 object was converted from a dict to a specialized structseq object.
7368
Georg Brandl3ee81df2008-05-17 18:14:43 +00007369- Patch #1816: Added sys.flags structseq. It exposes the status of
7370 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007371
Georg Brandl3ee81df2008-05-17 18:14:43 +00007372- Objects/structseq.c: Implemented new structseq representation. The
7373 patch makes structseqs (e.g. the return value of os.stat) more
7374 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007375
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Patch #1700288: added a type attribute cache that caches method
7377 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007378
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007379- Bug #1776: __import__() no longer accepts filenames on any platform.
7380 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007381
Georg Brandlaed6c662008-01-07 17:25:53 +00007382- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7383
Georg Brandl3ee81df2008-05-17 18:14:43 +00007384- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7385 envvar and sys.dont_write_bytecode attribute. All these can be set
7386 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007387
Georg Brandl3ee81df2008-05-17 18:14:43 +00007388- Improve some exception messages when Windows fails to load an
7389 extension module. Now we get for example '%1 is not a valid Win32
7390 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007391

7395 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007396
Christian Heimes0a8143f2007-12-18 23:22:54 +00007397- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007398 and INF. float("nan"), float("inf") and float("-inf") now work on
7399 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007400
Georg Brandl3ee81df2008-05-17 18:14:43 +00007401- Compiler now generates simpler and faster code for dictionary
7402 literals. The oparg for BUILD_MAP now indicates an estimated
7403 dictionary size. There is a new opcode, STORE_MAP, for adding
7404 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007414- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007415 SystemError.
7416
Nick Coghlanef01d822007-12-03 12:55:17 +00007417- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007433- Patch #1739468: Directories and zipfiles containing a __main__.py
7434 file can now be directly executed by passing their name to the
7435 interpreter. The directory/zipfile is automatically inserted as the
7436 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007437
Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Issue #1265: Fix a problem with sys.settrace, if the tracing
7439 function uses a generator expression when at the same time the
7440 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007441
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007442- sets and frozensets now have an isdisjoint() method.
7443
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007444- optimize the performance of builtin.sum().
7445
Neal Norwitz44f326e2007-10-05 05:29:17 +00007446- Fix warnings found by the new version of the Coverity checker.
7447
Georg Brandl21e99f42010-03-07 15:23:59 +00007448- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007449 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7450 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007451
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452- Issue #1686386: Tuple's tp_repr did not take into account the
7453 possibility of having a self-referential tuple, which is possible
7454 from C code. Nor did object's tp_str consider that a type's tp_str
7455 could do something that could lead to an inifinite recursion.
7456 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7457 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Issue #1164: It was possible to trigger deadlock when using the
7460 'print' statement to write to a file since the GIL was not released
7461 as needed. Now PyObject_Print() does the right thing along with
7462 various tp_print implementations of the built-in types and those in
7463 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007464
Georg Brandl3ee81df2008-05-17 18:14:43 +00007465- Issue #1147: Exceptions were directly allowing string exceptions in
7466 their throw() method even though string exceptions no longer
7467 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007468
Georg Brandl3ee81df2008-05-17 18:14:43 +00007469- Issue #1096: Prevent a segfault from getting the repr of a very
7470 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007471
Brett Cannon1e534b52007-09-07 04:18:30 +00007472- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007473 PyObject_Call() never calling back out to Python code to trigger
7474 recursion depth updates/checks. Required the creation of a static
7475 RuntimeError instance in case normalizing an exception put the
7476 recursion check value past its limit. Fixes crashers
7477 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007478
Georg Brandl3ee81df2008-05-17 18:14:43 +00007479- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007492- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007493 __*__ attributes. (Some already existed, e.g., __doc__ and
7494 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007495
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007496- Add -3 option to the interpreter to warn about features that are
7497 deprecated and will be changed/removed in Python 3.0.
7498
Georg Brandl2134e752007-05-21 20:34:16 +00007499- Patch #1686487: you can now pass any mapping after '**' in function
7500 calls.
7501
Collin Winter62903052007-05-18 23:11:24 +00007502- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007503 "except E as target:". This is to provide forwards compatibility
7504 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007506- Deprecate BaseException.message as per PEP 352.
7507
Georg Brandl3ee81df2008-05-17 18:14:43 +00007508- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007509 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007511- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007512 setting a plain string, ie don't expand to single letter identifiers.
7513
Raymond Hettinger13936692007-04-11 18:40:58 +00007514- Request #1191699: Slices can now be pickled.
7515
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007516- Request #1193128: str.translate() now allows a None argument for
7517 translations that only remove characters without re-mapping the
7518 remaining characters.
7519
Georg Brandl5cb76c12007-03-21 09:00:39 +00007520- Patch #1682205: a TypeError while unpacking an iterable is no longer
7521 masked by a generic one with the message "unpack non-sequence".
7522
Neal Norwitzaa754b72007-03-21 06:39:48 +00007523- Remove unused file Python/fmod.c.
7524
Guido van Rossum143b5642007-03-23 04:58:42 +00007525- Bug #1683368: The object.__init__() and object.__new__() methods are
7526 now stricter in rejecting excess arguments. The only time when
7527 either allows excess arguments is when it is not overridden and the
7528 other one is. For backwards compatibility, when both are
7529 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007530 warning later). Also, type.__init__() insists on the same signature
7531 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007533- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7534 object to complex using its __complex__() method before falling back
7535 to the __float__() method. Therefore, the functions in the cmath
7536 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008509 that the SMTP.starttls() caller no longer needs to call ehlo()
8510 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008511 does not claim to support starttls. Adds the
8512 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8513 Fenner.

8593 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8594 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008611 time so that opening a database previously created with the DB_DUP
8612 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8613 opens. Specifically: dictionary assignment to a DB object will
8614 replace all values for a given key when the database allows
8615 duplicate values. DB users should use DB.put(k, v) when they want
8616 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008617

8623 characters with ASCII value less than 32. Also, it correctly quotes
8624 dots only if they occur on a single line, as opposed to the previous
8625 behavior of quoting dots if they are the second character of any
8626 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008627
