1754
Ned Deily18fae3f2013-01-31 01:24:55 -08001755- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1756 In particular, fix extension module build failures when trying to use
1757 32-bit-only installer Pythons on systems with Xcode 4 (currently
1758 OS X 10.8, 10.7, and optionally 10.6).
1759 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1760 * Since Xcode 4 removes ppc support, extension module builds now
1761 check for ppc compiler support and by default remove ppc and
1762 ppc64 archs when they are not available.
1763 * Extension module builds now revert to using system installed
1764 headers and libs (/usr and /System/Library) if the SDK used
1765 to build the interpreter is not installed or has moved.
1766 * Try to avoid building extension modules with deprecated
1767 and problematic Apple llvm-gcc compiler. If original compiler
1768 is not available, use clang instead by default.

2120 int.__pow__. These overflow checks were causing int.__pow__ to produce
2121 incorrect results with recent versions of Clang, as a result of the

2123 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002199- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2200 Distutils-based packages with C extension modules may fail because
2201 Apple has removed gcc-4.2, the version used to build python.org
2202 64-bit/32-bit Pythons. If the user does not explicitly override
2203 the default C compiler by setting the CC environment variable,
2204 Distutils will now attempt to compile extension modules with clang
2205 if gcc-4.2 is required but not found. Also as a convenience, if
2206 the user does explicitly set CC, substitute its value as the default
2207 compiler in the Distutils LDSHARED configuration variable for OS X.
2208 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2209 SDK, neither of which are available in Xcode 4. This change does not
2210 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002460- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2461 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2462 interpreter process. This could cause failures in non-Distutils subprocesses
2463 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002464 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002465 deployment target only in the environment of each build subprocess. It is
2466 still possible to globally override the default by setting
2467 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2468 greater or equal to the default value, the value with which the interpreter
2469 was built.

2499 the ticker doesn't have to wind down to zero from the old starting point
2500 before the new interval takes effect. And if the user increases the
2501 interval, it makes sure the new limit takes effect right away rather have an
2502 early task switch before recognizing the new interval.

Raymond Hettinger74f869e2010-09-13 22:14:36 +00003474- Issue #9826: OrderedDict.__repr__ can now handle self-referential
3475 values: d['x'] = d.
3476
Victor Stinner8fc843b2010-09-17 23:35:50 +00003477- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +00003478
Antoine Pitroue4195e82010-09-12 14:56:27 +00003479- Issue #9837: The read() method of ZipExtFile objects (as returned by
3480 ZipFile.open()) could return more bytes than requested.
3481
Raymond Hettinger20397532010-09-12 02:11:45 +00003482- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3483 This prevents user-created self-referencing ordered dictionaries from
3484 becoming permanently uncollectable GC garbage. The downside is that
3485 removing __del__ means that the internal doubly-linked list has to wait for
3486 GC collection rather than freeing memory immediately when the refcnt drops
3487 to zero.
3488
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003489- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003490 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003491 value.
3492
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003493- Issue #9792: In case of connection failure, socket.create_connection()
3494 would swallow the exception and raise a new one, making it impossible
3495 to fetch the original errno, or to filter timeout errors. Now the
3496 original error is re-raised.
3497
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003498- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3499 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3500 be updated back after the system call. Original patch by Brian Brazil.
3501
Antoine Pitroudca9de92010-09-04 17:52:26 +00003502- Issue #1100562: Fix deep-copying of objects derived from the list and

3506 ConfigParser.write.
3507
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003508- Issue #808164: Fixed socket.close to avoid references to globals, to
3509 avoid issues when socket.close is called from a __del__ method.
3510
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003511- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3512 can be set to False to turn off the previously undocumented 'popularity'
3513 heuristic. Patch by Terry Reedy and Eli Bendersky
3514
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003515- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3516 falling into recursion.
3517
R. David Murray7c4bf552010-08-25 01:45:57 +00003518- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3519 character years even if the message contains RFC822 two character years.
3520
Daniel Stutzbach91287322010-08-24 21:09:30 +00003521- Issue #8750: Fixed MutableSet's methods to correctly handle

3533 module now correctly return a set. (Patch by Eli Bendersky.)
3534
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003535- Issue #9617: Signals received during a low-level write operation aren't
3536 ignored by the buffered IO layer anymore.
3537
Benjamin Peterson52c36052010-08-21 03:03:22 +00003538- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3539 are not held onto after they are deleted elsewhere.
3540
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003541- Issue #9626: the view methods for collections.OrderedDict() were returning
3542 the unordered versions inherited from dict. Those methods are now
3543 overridden to provide ordered views.
3544
Éric Araujo0389ae62010-08-14 03:07:46 +00003545- Issue #8688: MANIFEST files created by distutils now include a magic
3546 comment indicating they are generated. Manually maintained MANIFESTs
3547 without this marker will not be overwritten or removed.
3548
Antoine Pitroue1436d12010-08-12 15:25:51 +00003549- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3550 and a BadZipfile error is raised if it doesn't match (as used to be the
3551 case in Python 2.5 and earlier).
3552
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003553- Issue #9550: a BufferedReader could issue an additional read when the
3554 original read request had been satisfied, which could block indefinitely
3555 when the underlying raw IO channel was e.g. a socket. Report and original
3556 patch by Jason V. Miller.
3557
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003558- Issue #9551: Don't raise TypeError when setting the value to None for
3559 SafeConfigParser instances constructed with allow_no_value == True.
3560

3575
Senthil Kumarane677ecf2010-08-08 11:56:31 +00003576- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3577 This is how it is supposed to work, wget and curl do the same. Previous
3578 behavior was wrong.

3586 the option character for the added 'h/help' option if prefix_chars
3587 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003945- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3946 start byte and the continuation byte(s) are now considered invalid, instead
3947 of the number of bytes specified by the start byte.
3948 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3949 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3950 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3960 objects. (1) The comparison could incorrectly return True in some cases
3961 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3962 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00004103- Issue #1533: Fix inconsistency in range function argument processing: any
4104 non-float non-integer argument is now converted to an integer (if possible)
4105 using its __int__ method. Previously, only small arguments were treated this
4106 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00004157- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4158 operation raises multiple signals and more than one of those signals is
4159 trapped, the specification determines the order in which the signals should be
4160 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004306 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4307 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

4328Core and Builtins
4329-----------------
4330
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004331- Issue #7301: Add environment variable $PYTHONWARNINGS.
4332
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004333- Issue #8329: Don't return the same lists from select.select when no fds are
4334 changed.
4335
Georg Brandlfee0f442010-05-22 21:26:21 +00004336- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004337 on 64-bit machines. The shift count for either left or right shift is
4338 permitted to be up to sys.maxsize.
4339
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004340- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004344- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4345
Georg Brandlfee0f442010-05-22 21:26:21 +00004346- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4347 with a non-empty format string. This is an effort to future-proof user
4348 code. If a derived class does not currently implement __format__ but later
4349 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004350 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004351 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004352
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004353- Issue #8268: Old-style classes (not just instances) now support weak

4365
Victor Stinner66644262010-03-10 22:30:19 +00004366- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004367 (SIGINT). If an error occurs while importing the site module, the error is

4383
Georg Brandlfee0f442010-05-22 21:26:21 +00004384- Issue #8257: The Decimal construct now accepts a float instance directly,
4385 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004386
4387 >>> Decimal(1.1)
4388 Decimal('1.100000000000000088817841970012523233890533447265625')
4389
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004390- collections.Counter() now supports a subtract() method.
4391
Georg Brandlfee0f442010-05-22 21:26:21 +00004392- The functools module now has a total_ordering() class decorator to simplify
4393 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004395- The functools module also adds cmp_to_key() as a tool to transition old-style
4396 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004397
Georg Brandlfee0f442010-05-22 21:26:21 +00004398- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4399 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004400
Georg Brandlfee0f442010-05-22 21:26:21 +00004401- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4402 InvalidOperation instead of returning False. (Comparisons involving a quiet
4403 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4404 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004405
Georg Brandlfee0f442010-05-22 21:26:21 +00004406- Issue #2531: Comparison operations between floats and Decimal instances now
4407 return a result based on the numeric values of the operands; previously they
4408 returned an arbitrary result based on the relative ordering of id(float) and
4409 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004410
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004411- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004412 argument `-` which tells it to read files to compile from stdin. Each line is
4413 read on demand and the named file is compiled immediately. (Original patch by
4414 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004419- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4420 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004421 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004422
Georg Brandlfee0f442010-05-22 21:26:21 +00004423- Comparisons using one of <, <=, >, >= between a complex instance and a
4424 Fractions instance now raise TypeError instead of returning True/False. This
4425 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4426 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004427

4531 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4532 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004533 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4534 inconsistent: __int__ was used for some integer codes but not for others, and
4535 the set of integer codes for which it was used differed between native packing
4536 and standard packing.)

4750 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4751 Xicluna who helped with the patch.

Georg Brandlba83f822010-03-14 09:50:54 +00004844 file position when calling `truncate()`. It would previously change the file
4845 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004846 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4847

4849 class used to represent files stored inside an archive. The new
4850 implementation is significantly faster and can be wrapped in a
4851 ``io.BufferedReader`` object for more speedups. It also solves an issue
4852 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004863- Issue #7748: Since unicode values are supported for some metadata options in
4864 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4865 encoded string for them. This ensures that the upload and register commands
4866 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005136- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5137 decimal string that's guaranteed to round back to x under correct rounding
5138 (with round-half-to-even rounding mode). Previously it gave a string based on
5139 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5140 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5141 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005142
Georg Brandlba83f822010-03-14 09:50:54 +00005143- Issue #7117: On almost all platforms: float-to-string and string-to-float
5144 conversions within Python are now correctly rounded. Places these conversions
5145 occur include: str for floats and complex numbers; the float and complex
5146 constructors; old-style and new-style numeric formatting; serialization and
5147 deserialization of floats and complex numbers using marshal, pickle and json;
5148 parsing of float and imaginary literals in Python code; Decimal-to-float
5149 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005150
Georg Brandlba83f822010-03-14 09:50:54 +00005151 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5152 providing correctly-rounded strtod and dtoa C functions. This code is
5153 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5154 the C compiler. There may be a small number of platforms on which correct
5155 operation of this code cannot be guaranteed, so the code is not used: notably,
5156 this applies to platforms where the C double format is not IEEE 754 binary64,
5157 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5158 and Python's configure script is unable to determine how to change the FPU
5159 precision. On these platforms conversions use the platform strtod and dtoa,
5160 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005161
Georg Brandlba83f822010-03-14 09:50:54 +00005162- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5163 uses the correctly-rounded string <-> float conversions described above (when
5164 available), and so produces correctly rounded results that will display nicely
5165 under the float repr. There are two related small changes: (1) round now
5166 accepts any class with an ``__index__()`` method for its second argument (but
5167 no longer accepts floats for the second argument), and (2) an excessively
5168 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5169 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005316- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5317 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5318 but with at least one decimal point and with a default precision
5319 of 12. Previously, the behavior the same but with a default precision of 6.
5320 This more closely matches ``str()``, and reduces surprises when adding
5321 alignment flags to the empty presentation type. This also affects the new
5322 complex.__format__ in the same way.
5323
5324- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5461
Georg Brandlba83f822010-03-14 09:50:54 +00005462- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5463 existing .py counterpart, override the co_filename attributes of all code
5464 objects if the original filename is obsolete (which can happen if the file has
5465 been renamed, moved, or if it is accessed through different paths). Patch by
5466 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00005470- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
5471 file with `str' filename on Windows.
5472
Antoine Pitrouaa687902009-01-01 14:11:22 +00005473- Issue #3680: Reference cycles created through a dict, set or deque iterator
5474 did not get collected.
5475
Georg Brandlba83f822010-03-14 09:50:54 +00005476- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
5477 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00005478
Benjamin Peterson7af65562008-12-29 17:56:58 +00005479- Issue #4764: With io.open, IOError.filename is set when trying to open a
5480 directory on POSIX systems.
5481
Benjamin Petersonfe231b02008-12-29 17:47:42 +00005482- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
5483 systems.
5484
Georg Brandl6425a2f2008-12-28 11:54:53 +00005485- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005486 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005487
Skip Montanarof205c132008-12-23 03:30:15 +00005488- Added test case to ensure attempts to read from a file opened for writing
5489 fail.
5490
Georg Brandlba83f822010-03-14 09:50:54 +00005491- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5492 elapsed times, not only when some objects are uncollectable/unreachable.
5493 Original patch by Neil Schemenauer.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00005502
Georg Brandlba83f822010-03-14 09:50:54 +00005503- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00005504
Georg Brandlba83f822010-03-14 09:50:54 +00005505- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5506 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5507 instances. On a typical machine this saves 3 bytes of memory (on average) per
5508 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005509
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005510- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5511 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5512 instead of throwing a MemoryError.
5513
Georg Brandlba83f822010-03-14 09:50:54 +00005514- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5515 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005516
Benjamin Petersonc078f922008-11-21 22:27:24 +00005517- Issue #4367: Python would segfault during compiling when the unicodedata
5518 module couldn't be imported and \N escapes were present.
5519
Georg Brandlba83f822010-03-14 09:50:54 +00005520- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5521 file objects with closefd=False. The file descriptor is still kept open but
5522 the file object behaves like a closed file. The ``FileIO`` object also got a
5523 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005524
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005525- Issue #4348: Some bytearray methods returned that didn't cause any change to
5526 the bytearray, returned the same bytearray instead of a copy.
5527
Georg Brandlba83f822010-03-14 09:50:54 +00005528- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00005530- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
5531
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005532- Issue #4048: The parser module now correctly validates relative imports.
5533
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005534- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5535 exec statement.
5536
Georg Brandlba83f822010-03-14 09:50:54 +00005537- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5538 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005539
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005540- Issue #4209: Enabling unicode_literals and the print_function in the same
5541 __future__ import didn't work.
5542
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005543- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005544 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005545
Georg Brandlba83f822010-03-14 09:50:54 +00005546- On windows, ``os.chdir()`` given unicode was not working if
5547 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5548 this code path is really executed because I cannot move to such directory on
5549 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005550
Georg Brandlba83f822010-03-14 09:50:54 +00005551- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5552 element is temporarily replaced with an equivalent frozenset. But the
5553 eventual KeyError would always report the empty ``frozenset()`` as the missing
5554 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00005556- Issue #4509: Various issues surrounding resize of bytearray objects to which

5562
Gregory P. Smithae91d092009-03-02 05:13:57 +00005563- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5564
Georg Brandlba83f822010-03-14 09:50:54 +00005565- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00005568- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5569 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005571- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5572 returned them on 64bit platforms.
5573
Walter Dörwalded960ac2009-05-03 22:36:33 +00005574- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5575 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5576 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5577 of using the replace error handler in PyUnicode_DecodeUTF8().
5578
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005579- Issue #3739: The unicode-internal encoder now reports the number of characters
5580 consumed like any other encoder (instead of the number of bytes).
5581
Georg Brandlba83f822010-03-14 09:50:54 +00005582- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5583 allocator will be automatically disabled when running under Valgrind. This
5584 gives improved memory leak detection when running under Valgrind, while taking
5585 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006830- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6831 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006832 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6833 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006838- Issue #5354: New test support function import_fresh_module() makes it easy to
6839 import both normal and optimised versions of modules. test_heapq and
6840 test_warnings have been adjusted to use it, tests for other modules with both
6841 C and Python implementations in the stdlib can be adjusted to use it over
6842 time.

6851 should cause a test to be skipped are now done using import_module from test
6852 support, which does the conversion.

6954
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006955- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6956 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6957 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6958 ``printf`` function, whereas PyString_FromFormat has an independent
6959 implementation and uses "%zd" on all platforms for size_t values.
6960 This makes a difference on win64, where ``printf`` needs "%Id" to display
6961 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006963- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6967 object; previously an int would be returned for small values. the __long__
6968 method is allowed to return either an int or a long, but the behaviour of
6969 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006978 was correctly parsed but parsing of subsequent arguments failed.
6979
Vinay Sajip35e3b032008-09-01 14:33:59 +00006980- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006981 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6982 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6983 when given a tuple of classes as second argument, were looking up
6984 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6985 type object.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00007113- Issue #3833: Use a different upgrade code for Win64 installers.
7114
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00007115- Issue #2271: Set SecureCustomProperties so that installation will properly
7116 use the TARGETDIR even for unprivileged users.
7117
Martin v. Löwis67543a92008-09-08 12:02:45 +00007118- Allow passing the MSI file name to merge.py.
7119
Vinay Sajip844f7412008-09-09 13:42:08 +00007120- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00007121 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007124What's New in Python 2.6 beta 3?
7125================================
7126
Barry Warsaw07a4a382008-08-21 01:15:08 +00007127*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007128
7129Core and Builtins
7130-----------------
7131
Guido van Rossumf8402962008-08-20 15:01:50 +00007132- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7133 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7134 extensions do not automatically benefit from the class attribute
7135 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7136 to their tp_flags field if they care. This is a backwards
7137 compatibility feature; in 3.0, all types will use the cache by
7138 default.
7139
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007140- Keyword arguments can now follow starred arguments. (``f(a, *args,
7141 keyword=23)`` is now valid syntax.)
7142
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007143- ctypes function pointers that are COM methods have a boolean True
7144 value again.
7145
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007146- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7147 by denying s# to parse objects that have a releasebuffer procedure,
7148 and introducing s*.
7149
Georg Brandl1e13ea92008-08-11 09:07:59 +00007150- Issue #3537: Fix an assertion failure when an empty but presized dict
7151 object was stored in the freelist.
7152
Mark Dickinsonb6467572008-08-04 21:30:09 +00007153- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7154 ValueError consistently across platforms.
7155
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007156- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7157 (64bit Unix, for example), unichr() would truncate its argument and return
7158 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7159
Neal Norwitze7d8be82008-07-31 17:17:14 +00007160- Apply security patches from Apple.
7161
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007162- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7163 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7164
Antoine Pitrou92f82162008-07-25 22:22:08 +00007165- Issue #1819: function calls with several named parameters are now on
7166 average 35% faster (as measured by pybench).
7167
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007168- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7169 the python debugger steps into a class statement: the free variables (local
7170 variables defined in an outer scope) would be deleted from the outer scope.
7171
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007172- Issue #2620: Overflow checking when allocating or reallocating memory
7173 was not always being done properly in some python types and extension
7174 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7175 all been updated to perform better checks and places in the code that
7176 would previously leak memory on the error path when such an allocation
7177 failed have been fixed.
7178
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007179Library
7180-------
7181
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007182- Issue #3612: Added some missing basic types in ctypes.wintypes.
7183
Benjamin Petersone977ad42008-08-20 01:42:01 +00007184- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7185 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7186
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007187- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7188 version reported by these tools does not necessarily follow the python
7189 version numbering scheme, so the module is less strict when parsing it.
7190
Nick Coghlanf70385a2008-08-18 12:42:46 +00007191- Issue #2235: Added Py3k warnings for types which will become unhashable
7192 under the stricter __hash__ inheritance rules in 3.0. Several types
7193 which did not meet the rules for hash invariants and were already
7194 unhashable in 3.0 have now been explicitly flagged as unhashable in
7195 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7196 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7197
Brett Cannon88f801d2008-08-18 00:46:22 +00007198- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7199 imported into the module but exposed as part of the module's API.
7200
Brett Cannon7b96f072008-08-18 00:41:11 +00007201- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7202
Brett Cannon46225e72008-08-18 00:36:52 +00007203- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7204
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007205- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7206
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007207- Issue #3575: Incremental decoder's decode function now takes bytearray
7208 by using 's*' instead of 't#'.
7209
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007210- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007211 fails unicode conversion on 2nd parameter. (windows only)
7212
Georg Brandl222e2082010-08-01 22:27:39 +00007213- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007214 in a redirect.
7215
Brett Cannonabe423e2008-08-16 21:47:07 +00007216- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007217 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007218
Facundo Batistaeb90b782008-08-16 14:44:07 +00007219- Issue #2776: fixed small issue when handling an URL with double slash
7220 after a 302 response in the case of not going through a proxy.
7221
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007222- Issue #2676: in the email package, content-type parsing was hanging on
7223 pathological input because of quadratic or exponential behaviour of a
7224 regular expression.
7225
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007226- Issue #3476: binary buffered reading through the new "io" library is now
7227 thread-safe.
7228
Brett Cannonbf3157b2008-08-14 05:00:03 +00007229- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7230 since mimetools itself is deprecated. Because modules are cached, all
7231 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7232
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007233- Issue #3134: shutil referenced undefined WindowsError symbol.
7234
Robert Schuppenies14646332008-08-10 11:01:53 +00007235- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7236 menu entries were not deleted.
7237
Brett Cannon83e81842008-08-09 23:30:55 +00007238- Copied the implementation of reduce() to _functools.reduce() to have a
7239 version that did not raise a DeprecationWarning under -3.
7240
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007241- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7242 a MemoryError rather than silently stop the iteration.
7243
Guido van Rossum59ce9012008-08-09 14:55:34 +00007244- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7245 to _sre.compile() will now be rejected. This should not affect anybody
7246 since the re.compile() function never generates invalid re-bytecode.
7247
Skip Montanaroa032bf42008-08-08 22:52:51 +00007248- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7249 upon first access it can be automatically initialized from the csv file if
7250 it wasn't initialized during instantiation.
7251
Brett Cannon3aa2a492008-08-06 22:28:09 +00007252- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7253 the reload() built-in has been removed.
7254
Brett Cannon7e30b672008-08-04 21:52:25 +00007255- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007256 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007257 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7258 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7259 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7260 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7261 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007262
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007263- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7264 raised an AttributeError.
7265
Benjamin Peterson01a24322008-07-28 23:35:27 +00007266- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007267 asking for a specific length. This problem only affected files opened
7268 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007269
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007270- Issue #3449: Update decimal module to use most recent specification
7271 (v. 1.68) and tests (v. 2.58) from IBM.
7272
Georg Brandl222e2082010-08-01 22:27:39 +00007273- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007274
Georg Brandl222e2082010-08-01 22:27:39 +00007275- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00007276 on a closed shelf.
7277
Georg Brandlf9efabb2008-07-23 15:16:45 +00007278- Deprecate the "ast" parser function aliases.
7279
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007280- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7281
7282- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7283 invalid arguments.
7284
7285- Issue #3302: Fix several crashes when calling locale's gettext functions
7286 with None arguments.
7287
7288- Issue #3389: Allow resolving dotted names for handlers in logging
7289 configuration files.
7290
7291- Deprecate the sunaudio module for removal in Python 3.0.
7292
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007293- Issue #3394: zipfile.writestr sets external attributes when passed a
7294 file name rather than a ZipInfo instance, so files are extracted with
7295 mode 0600 rather than 000 under Unix.
7296
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007297- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7298 argument in python 2.5, this broke code that subclassed Popen to include its
7299 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7307-------------
7308
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007309- Issue #2235: the C API function PyObject_HashNotImplemented and its
7310 interaction with the tp_hash slot (added in 2.6b2) are now documented
7311
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007312- Issue #643841: The language reference now provides more detailed
7313 coverage of the lookup process for special methods. The disclaimers
7314 regarding lack of coverage of new-style classes have also been
7315 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007318What's New in Python 2.6 beta 2?
7319================================
7320
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007321*Release date: 17-Jul-2008*
7322
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007323Core and Builtins
7324-----------------
7325
Georg Brandl3e483f62008-07-16 22:57:41 +00007326- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7327 its methods now allow for items objects that can be converted to
7328 an integer using operator.index().
7329
Mark Dickinson64b7e502008-07-16 09:40:03 +00007330- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7331 produced a ValueError instead of giving the correct float.
7332
Eric Smitha5fa5a22008-07-16 00:11:49 +00007333- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7334 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7335
Mark Dickinson7103aa42008-07-15 19:08:33 +00007336- Issue #3008: the float type has a new instance method 'float.hex'
7337 and a new class method 'float.fromhex' to convert floating-point
7338 numbers to and from hexadecimal strings, respectively.
7339
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007340- Issue #2235: __hash__ is once again inherited by default. To allow
7341 collections.Hashable to remain meaningful in the presence of the
7342 default hash implementation (object.__hash__), it is now possible
7343 to explicit block inheritance of hash by setting __hash__=None at
7344 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7345 level.
7346
Nick Coghlanb028f502008-07-13 14:52:36 +00007347- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7348 the parent module cannot be found while performing an absolute import.
7349 This means that an incorrectly defined __package__ attribute will
7350 now only prevent relative imports in that module rather than causing
7351 all imports from that module to fail.
7352
Nick Coghlan14ff9942008-07-08 14:21:42 +00007353- Issue #2517: Allow unicode messages in Exceptions again by correctly
7354 bypassing the instance dictionary when looking up __unicode__ on
7355 new-style classes.
7356
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007357- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7358 set to a custom object whose write() method happens to install
7359 another file in sys.stdout.
7360
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007361- Issue #3088: Corrected a race condition in classes derived from
7362 threading.local: the first member set by a thread could be saved in
7363 another thread's dictionary.
7364
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007365- Issue #3004: Minor change to slice.indices(): the start and stop
7366 arguments are now treated identically, making the behaviour easier
7367 to describe and understand. For example, slice(None, -10,
7368 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7369 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7370 10, -1).
7371
Georg Brandl278fc502008-07-19 12:46:12 +00007372- Issue #3219: Calling a function with repeated keyword arguments,
7373 f(a=2, a=23), would not cause a syntax error. This was a regression
7374 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007375
Georg Brandl278fc502008-07-19 12:46:12 +00007376- Issue #2862: Make int and float freelist management consistent with
7377 other freelists. Changes their CompactFreeList apis into
7378 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007383- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7384 api functions without holding the GIL, which could lead to a fatal
7385 error when they failed.
7386
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007387- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7396 ForkingPickler.register() to resolve conflict with ctypes.

7819
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007820- On MacOS X it is now possible to install the framework in 64-bit
7821 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007822 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007823
7824 This is controlled by the configure argument ``--with-universal-archs``:
7825
7826 - ``--with-universal-archs=all``: install 4-way universal
7827
7828 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7829
7830 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7831
7832 This option should be used in combination with ``--enable-universalsdk=``.
7833
7834 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 +00007883- Issue #1631171: Re-implement the 'warnings' module in C (the
7884 original Python code has been kept as backup). This will allow for
7885 using the 'warning's machinery in such places as the parser where
7886 use of pure Python code is not possible. Both the ``showarning()``
7887 and ``formatwarning()`` gain an optional 'line' argument which is
7888 not called by default for backwards-compatibility reasons. Setting
7889 ``warnings.showwarning()`` to an implementation that lacks support
7890 for the ``line`` argument will raise a DeprecationWarning.

7914
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007915- The getpass module has been improved on Unix. It now uses /dev/tty
7916 by default and uses stderr instead of stdout. A GetPassWarning is
7917 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007918

Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007933 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Issue #2550: The approach used by client/server code for obtaining
7954 ports to listen on in network-oriented tests has been refined in an
7955 effort to facilitate running multiple instances of the entire
7956 regression test suite in parallel without issue.
7957 test_support.bind_port() has been fixed such that it will always
7958 return a unique port -- which wasn't always the case with the
7959 previous implementation, especially if socket options had been set
7960 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7961 new implementation of bind_port() will actually raise an exception
7962 if it is passed an AF_INET/SOCK_STREAM socket with either the
7963 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7964 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7965 the socket it's been passed. This currently only applies to
7966 Windows. This option prevents any other sockets from binding to the
7967 host/port we've bound to, thus removing the possibility of the
7968 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7969 when a second SOCK_STREAM socket binds and accepts to a host/port
7970 that's already been bound by another socket. The optional preferred
7971 port parameter to bind_port() has been removed. Under no
7972 circumstances should tests be hard coding ports!
7973
7974 test_support.find_unused_port() has also been introduced, which will
7975 pass a temporary socket object to bind_port() in order to obtain an
7976 unused port. The temporary socket object is then closed and
7977 deleted, and the port is returned. This method should only be used
7978 for obtaining an unused port in order to pass to an external program
7979 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7980 a parameter to a server-oriented class that doesn't give you direct
7981 access to the underlying socket used.
7982
7983 Finally, test_support.HOST has been introduced, which should be used
7984 for the host argument of any relevant socket calls (i.e. bind and
7985 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007986
7987 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007989 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7990 test_asynchat and test_socket_ssl.
7991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992 It is now possible for multiple instances of the regression test
7993 suite to run in parallel without issue.

8260-----------------
8261
Fred Drakea8ee94b2008-03-01 02:45:07 +00008262- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008263 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008264
Georg Brandlad61bc82008-02-23 15:11:18 +00008265- Issue #2067: file.__exit__() now calls subclasses' close() method.
8266
8267- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008268
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008269- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008270 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008271
Eric Smitha73fbe72008-02-23 03:09:44 +00008272- Added the future_builtins module, which contains hex() and oct().
8273 These are the PEP 3127 version of these functions, designed to be
8274 compatible with the hex() and oct() builtins from Python 3.0. They
8275 differ slightly in their output formats from the existing, unchanged
8276 Python 2.6 builtins. The expected usage of the future_builtins
8277 module is:
8278 from future_builtins import hex, oct
8279
Eric Smith7ef40bf2008-02-20 23:34:22 +00008280- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8281 exponents for exponents with absolute value < 100. Follows C99
8282 standard. This is a change on Windows, which would use 3 digits.
8283 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8284 so that any alterations it does to the resulting string will be
8285 available in stringlib/formatter.h (for float.__format__).
8286
Eric Smith5a3c1352008-02-19 13:21:56 +00008287- Implemented PEP 3101, Advanced String Formatting. This adds a new
8288 builtin format(); a format() method for str and unicode; a
8289 __format__() method to object, str, unicode, int, long, float, and
8290 datetime; the class string.Formatter; and the C API
8291 PyObject_Format().
8292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Fixed several potential crashes, all caused by specially crafted
8294 __del__ methods exploiting objects in temporarily inconsistent
8295 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008296
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008297- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008298 prevent a possible crash: an Abstract Base Class would try to access
8299 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008300
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301- Fixed repr() and str() of complex numbers with infinity or nan as
8302 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008303
Georg Brandl3ee81df2008-05-17 18:14:43 +00008304- Clear all free lists during a gc.collect() of the highest generation
8305 in order to allow pymalloc to free more arenas. Python may give back
8306 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Issue #2045: Fix an infinite recursion triggered when printing a
8309 subclass of collections.defaultdict, if its default_factory is set
8310 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008311
Christian Heimesf75dbef2008-02-08 00:11:31 +00008312- Fixed a minor memory leak in dictobject.c. The content of the free
8313 list was not freed on interpreter shutdown.
8314
Georg Brandl21e99f42010-03-07 15:23:59 +00008315- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008316 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8319 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008320 to compact the internal free lists of pre-allocted ints and floats.
8321
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8323 calls. Python expected the return type int but the fork familie
8324 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008325
Georg Brandl3ee81df2008-05-17 18:14:43 +00008326- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8327 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008328

Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8336 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008337
Georg Brandl3ee81df2008-05-17 18:14:43 +00008338- Patch #1473257: generator objects gain a gi_code attribute. This is
8339 the same object as the func_code attribute of the function that
8340 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008341
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342- Issue #1920: "while 0" statements were completely removed by the
8343 compiler, even in the presence of an "else" clause, which is
8344 supposed to be run when the condition is false. Now the compiler
8345 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008346
Guido van Rossumeead05f2008-01-24 18:21:02 +00008347- A few crashers fixed: weakref_in_del.py (issue #1377858);
8348 loosing_dict_ref.py (issue #1303614, test67.py);
8349 borrowed_ref_[34].py (not in tracker).
8350
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008351- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008352 suppressed while an extension is loaded by calling SetErrorMode in
8353 dynload_win.c. The error is still reported properly.
8354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008356 several extension methods and modules do not work without unicode
8357 support.
8358
Georg Brandl26543b12008-01-21 18:36:51 +00008359- Issue #1882: when compiling code from a string, encoding cookies in the
8360 second line of code were not always recognized correctly.
8361
Georg Brandl14404b62008-01-19 19:27:05 +00008362- Issue #1679: "0x" was taken as a valid integer literal.
8363
Georg Brandl6caad7d2008-01-26 14:19:22 +00008364- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008365 added.
8366
Christian Heimesc94e2b52008-01-14 04:13:37 +00008367- sys.float_info / PyFloat_GetInfo: The floating point information
8368 object was converted from a dict to a specialized structseq object.
8369
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370- Patch #1816: Added sys.flags structseq. It exposes the status of
8371 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008372
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373- Objects/structseq.c: Implemented new structseq representation. The
8374 patch makes structseqs (e.g. the return value of os.stat) more
8375 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008376
Georg Brandl3ee81df2008-05-17 18:14:43 +00008377- Patch #1700288: added a type attribute cache that caches method
8378 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008379

8386 envvar and sys.dont_write_bytecode attribute. All these can be set
8387 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008388
Georg Brandl3ee81df2008-05-17 18:14:43 +00008389- Improve some exception messages when Windows fails to load an
8390 extension module. Now we get for example '%1 is not a valid Win32
8391 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008399 and INF. float("nan"), float("inf") and float("-inf") now work on
8400 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008401
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402- Compiler now generates simpler and faster code for dictionary
8403 literals. The oparg for BUILD_MAP now indicates an estimated
8404 dictionary size. There is a new opcode, STORE_MAP, for adding
8405 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008453- Issue #1686386: Tuple's tp_repr did not take into account the
8454 possibility of having a self-referential tuple, which is possible
8455 from C code. Nor did object's tp_str consider that a type's tp_str
8456 could do something that could lead to an inifinite recursion.
8457 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8458 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008460- Issue #1164: It was possible to trigger deadlock when using the
8461 'print' statement to write to a file since the GIL was not released
8462 as needed. Now PyObject_Print() does the right thing along with
8463 various tp_print implementations of the built-in types and those in
8464 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008465
Georg Brandl3ee81df2008-05-17 18:14:43 +00008466- Issue #1147: Exceptions were directly allowing string exceptions in
8467 their throw() method even though string exceptions no longer
8468 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008470- Issue #1096: Prevent a segfault from getting the repr of a very
8471 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008472
Brett Cannon1e534b52007-09-07 04:18:30 +00008473- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008474 PyObject_Call() never calling back out to Python code to trigger
8475 recursion depth updates/checks. Required the creation of a static
8476 RuntimeError instance in case normalizing an exception put the
8477 recursion check value past its limit. Fixes crashers
8478 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008493- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494 __*__ attributes. (Some already existed, e.g., __doc__ and
8495 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008496
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008497- Add -3 option to the interpreter to warn about features that are
8498 deprecated and will be changed/removed in Python 3.0.
8499
Georg Brandl2134e752007-05-21 20:34:16 +00008500- Patch #1686487: you can now pass any mapping after '**' in function
8501 calls.
8502
Collin Winter62903052007-05-18 23:11:24 +00008503- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008504 "except E as target:". This is to provide forwards compatibility
8505 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008512- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008513 setting a plain string, ie don't expand to single letter identifiers.
8514
Raymond Hettinger13936692007-04-11 18:40:58 +00008515- Request #1191699: Slices can now be pickled.
8516
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008517- Request #1193128: str.translate() now allows a None argument for
8518 translations that only remove characters without re-mapping the
8519 remaining characters.
8520
Georg Brandl5cb76c12007-03-21 09:00:39 +00008521- Patch #1682205: a TypeError while unpacking an iterable is no longer

Neal Norwitzaa754b72007-03-21 06:39:48 +00008524- Remove unused file Python/fmod.c.
8525
Guido van Rossum143b5642007-03-23 04:58:42 +00008526- Bug #1683368: The object.__init__() and object.__new__() methods are
8527 now stricter in rejecting excess arguments. The only time when
8528 either allows excess arguments is when it is not overridden and the
8529 other one is. For backwards compatibility, when both are
8530 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008531 warning later). Also, type.__init__() insists on the same signature
8532 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008534- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8535 object to complex using its __complex__() method before falling back
8536 to the __float__() method. Therefore, the functions in the cmath
8537 module now can operate on objects that define a __complex__()
8538 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008556- Bug #1678647: write a newline after printing an exception in any
8557 case, even when converting the value to a string failed.
8558
Georg Brandl871f1bc2007-03-12 13:17:36 +00008559- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008560 its argument, if it exists. If not, it will work like before. This
8561 allows customizing the output of dir() in the presence of a
8562 __getattr__().

8571 parthensized forms. This means complex(repr(x)) now works instead of
8572 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008573
Georg Brandlaa2321b2007-03-07 00:40:28 +00008574- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008575 makes the filenames the warning module prints much more sensible
8576 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008589- Patch #1674228: when assigning a slice (old-style), check for the
8590 sq_ass_slice instead of the sq_slice slot.
8591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- When printing an unraisable error, don't print exceptions. before

Neal Norwitzdac090d2006-09-05 03:53:08 +00008694- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008695 generator expressions (x for x, in ... ) works again. Fixing this

9222 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009497- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9498 with RFC 3207 and forgets any knowledge obtained from the server not
9499 obtained from the TLS negotiation itself. Patch contributed by Bill
9500 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009501
Georg Brandl3ee81df2008-05-17 18:14:43 +00009502- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009503 that the SMTP.starttls() caller no longer needs to call ehlo()
9504 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009505 does not claim to support starttls. Adds the
9506 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9587 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9588 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009605 time so that opening a database previously created with the DB_DUP
9606 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9607 opens. Specifically: dictionary assignment to a DB object will
9608 replace all values for a given key when the database allows
9609 duplicate values. DB users should use DB.put(k, v) when they want
9610 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009611

9617 characters with ASCII value less than 32. Also, it correctly quotes
9618 dots only if they occur on a single line, as opposed to the previous
9619 behavior of quoting dots if they are the second character of any
9620 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009621

9948-----
9949
Georg Brandl3ee81df2008-05-17 18:14:43 +00009950- Unified naming convention for free lists and their limits. All free
9951 lists in Object/ are named ``free_list``, the counter ``numfree``
9952 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9953 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009954
Georg Brandl3ee81df2008-05-17 18:14:43 +00009955- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9956 to ``PyTuple_SetItem``, it can be used to populate a brand new
9957 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009958
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009959- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

9966
9967- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9968 ``PyFloat_GetInfo()`` to the float API.
9969
Georg Brandl3ee81df2008-05-17 18:14:43 +00009970- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9971 of w# format code incorrectly truncated the length to an int, even
9972 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9973 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009974
Georg Brandl3ee81df2008-05-17 18:14:43 +00009975- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9993- Fix some leftovers from the conversion from int to Py_ssize_t
9994 (relevant to strings and sequences of more than 2**31 items).
9995
9996- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9997 outside of pystate.c and should not be necessary.
9998
Georg Brandl3ee81df2008-05-17 18:14:43 +00009999- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10000 absolute imports. In earlier versions they might have used relative
10001 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010002
Georg Brandl3ee81df2008-05-17 18:14:43 +000010003- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10004 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010005
Georg Brandl3ee81df2008-05-17 18:14:43 +000010006- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010012- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10013 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10014 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10015 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010016

Georg Brandl3ee81df2008-05-17 18:14:43 +000010029- Removed the macfs module. It had been deprecated since Python 2.5.
10030 This lead to the deprecation of macostools.touched() as it relied
10031 solely on macfs and was a no-op under OS X.
