Ned Deily18fae3f2013-01-31 01:24:55 -08001325- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1326 In particular, fix extension module build failures when trying to use
1327 32-bit-only installer Pythons on systems with Xcode 4 (currently
1328 OS X 10.8, 10.7, and optionally 10.6).
1329 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1330 * Since Xcode 4 removes ppc support, extension module builds now
1331 check for ppc compiler support and by default remove ppc and
1332 ppc64 archs when they are not available.
1333 * Extension module builds now revert to using system installed
1334 headers and libs (/usr and /System/Library) if the SDK used
1335 to build the interpreter is not installed or has moved.
1336 * Try to avoid building extension modules with deprecated
1337 and problematic Apple llvm-gcc compiler. If original compiler
1338 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001762- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001763 has left two versions of customize_compiler, the original in
1764 distutils.sysconfig and another copy in distutils.ccompiler, with some
1765 parts of distutils calling one and others using the other.
1766 Complete the revert back to only having one in distutils.sysconfig as
1767 is the case in 3.x.
1768
Ned Deily0d0ea482012-02-10 12:59:06 +01001769- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1770 Distutils-based packages with C extension modules may fail because
1771 Apple has removed gcc-4.2, the version used to build python.org
1772 64-bit/32-bit Pythons. If the user does not explicitly override
1773 the default C compiler by setting the CC environment variable,
1774 Distutils will now attempt to compile extension modules with clang
1775 if gcc-4.2 is required but not found. Also as a convenience, if
1776 the user does explicitly set CC, substitute its value as the default
1777 compiler in the Distutils LDSHARED configuration variable for OS X.
1778 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1779 SDK, neither of which are available in Xcode 4. This change does not
1780 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002030- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2031 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2032 interpreter process. This could cause failures in non-Distutils subprocesses
2033 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002034 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002035 deployment target only in the environment of each build subprocess. It is
2036 still possible to globally override the default by setting
2037 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2038 greater or equal to the default value, the value with which the interpreter
2039 was built.

2068 updating the check interval, so if the user decreases the check interval,
2069 the ticker doesn't have to wind down to zero from the old starting point
2070 before the new interval takes effect. And if the user increases the
2071 interval, it makes sure the new limit takes effect right away rather have an
2072 early task switch before recognizing the new interval.

3053 This prevents user-created self-referencing ordered dictionaries from
3054 becoming permanently uncollectable GC garbage. The downside is that

3514
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003515- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3516 start byte and the continuation byte(s) are now considered invalid, instead
3517 of the number of bytes specified by the start byte.
3518 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3519 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3520 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3521 Previous versions returned a single u'\ufffd'.
3522
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003523- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003524 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3525 arises from the "Overriding __eq__ blocks inheritance ..." warning
3526 when turned into an exception: in this case the exception simply
3527 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003528
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003529- Issue #8748: Fix two issues with comparisons between complex and integer
3530 objects. (1) The comparison could incorrectly return True in some cases
3531 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3532 (2) The comparison raised an OverflowError for large integers, leading
3533 to unpredictable exceptions when combining integers and complex objects
3534 in sets or dicts.
3535
Mark Dickinson81336372010-05-30 12:12:25 +00003536- Issue #5211: Implicit coercion for the complex type is now completely
3537 removed. (Coercion for arithmetic operations was already removed in 2.7
3538 alpha 4, but coercion for rich comparisons was accidentally left in.)
3539
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003540- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3541 and error handler, instead of writing to the C stderr file in utf-8
3542
Georg Brandlfee0f442010-05-22 21:26:21 +00003543- Issue #7902: When using explicit relative import syntax, don't try implicit
3544 relative import semantics.

3902
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003903- Issue #8329: Don't return the same lists from select.select when no fds are
3904 changed.
3905
Georg Brandlfee0f442010-05-22 21:26:21 +00003906- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00003916- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3917 with a non-empty format string. This is an effort to future-proof user
3918 code. If a derived class does not currently implement __format__ but later
3919 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003920 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003921 Python 3.3 and it will be an error in Python 3.4.

3972 InvalidOperation instead of returning False. (Comparisons involving a quiet
3973 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlfee0f442010-05-22 21:26:21 +00003976- Issue #2531: Comparison operations between floats and Decimal instances now
3977 return a result based on the numeric values of the operands; previously they
3978 returned an arbitrary result based on the relative ordering of id(float) and
3979 id(Decimal).

Georg Brandlba83f822010-03-14 09:50:54 +00004292- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00004293 thread could raise an incorrect RuntimeError about not holding the import
4294 lock. The import lock is now reinitialized after fork.

Georg Brandlba83f822010-03-14 09:50:54 +00004315- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004316 is run with the -OO flag. Tests requiring docstrings are skipped.
4317
Georg Brandlba83f822010-03-14 09:50:54 +00004318- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4319 now also used by regrtest to run all the tests in a temporary directory. The
4320 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4321 Xicluna who helped with the patch.

4338 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004339 library would return a bogus result; on Solaris, it was possible to crash the
4340 interpreter. Patch by Stefan Krah.

4351 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00004352
Georg Brandlba83f822010-03-14 09:50:54 +00004353- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4354 and add the additional members returned in an OSVERSIONINFOEX structure. The
4355 new members are service_pack_major, service_pack_minor, suite_mask, and
4356 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00004357
Georg Brandlba83f822010-03-14 09:50:54 +00004358- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4359 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4360 returning NULL. The macro now returns a statically allocated empty string
4361 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00004362
Antoine Pitrou64672132010-01-13 07:55:48 +00004363- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00004370 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4371 strings,
4372 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4373 numeric strings corresponding to subnormal values,
4374 (3) a memory leak for some values large enough to cause overflow, and
4375 (4) a number of flaws that could lead to incorrectly rounded results.
4376
4377- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
4378 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00004379

4391
R. David Murray63e4fd72010-02-10 22:42:04 +00004392- Issue #7835: shelve should no longer produce mysterious warnings during
4393 interpreter shutdown.
4394
Georg Brandlba83f822010-03-14 09:50:54 +00004395- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4396 XML processing instructions and comments. These raw characters are allowed
4397 by the XML specification, and are necessary when outputting e.g. PHP code in
4398 a processing instruction. Patch by Neil Muller.

Georg Brandlba83f822010-03-14 09:50:54 +00004404- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00004405
Antoine Pitroud840e512010-02-04 20:20:18 +00004406- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004407 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004408 Also, raise ValueError rather than TypeError when an unknown TIPC address
4409 type is specified. Patch by Brian Curtin.
4410
Vinay Sajip28c382f2010-02-04 18:48:53 +00004411- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004413- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004414 file position when calling `truncate()`. It would previously change the file
4415 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004416 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4417
Georg Brandlba83f822010-03-14 09:50:54 +00004418- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4419 class used to represent files stored inside an archive. The new
4420 implementation is significantly faster and can be wrapped in a
4421 ``io.BufferedReader`` object for more speedups. It also solves an issue
4422 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4423 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00004424
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004425- Issue #7792: Registering non-classes to ABCs raised an obscure error.

4431 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004432
Georg Brandlba83f822010-03-14 09:50:54 +00004433- Issue #7748: Since unicode values are supported for some metadata options in
4434 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4435 encoded string for them. This ensures that the upload and register commands
4436 send the correct values to PyPI without any error.

4512
Georg Brandlba83f822010-03-14 09:50:54 +00004513- The ``__complex__()`` method is now looked up on the class of instances to
4514 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004515

4518
Mark Dickinson1b34d252010-01-01 17:27:30 +00004519- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004520 DeprecationWarning when passed a float argument where an integer was expected.
4521 These functions and methods now raise TypeError instead. The majority of the
4522 effects of this change are in the extension modules, but some core functions
4523 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4524 and many unicode/str methods.

4538 of integers: the result of a/b is now correctly rounded for ints a and b (at
4539 least on IEEE 754 platforms), and in particular does not depend on the
4540 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004549 These executables now work properly with the arch(1) command: ``arch -ppc

4697 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004706- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4707 decimal string that's guaranteed to round back to x under correct rounding
4708 (with round-half-to-even rounding mode). Previously it gave a string based on
4709 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4710 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4711 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004713- Issue #7117: On almost all platforms: float-to-string and string-to-float
4714 conversions within Python are now correctly rounded. Places these conversions
4715 occur include: str for floats and complex numbers; the float and complex
4716 constructors; old-style and new-style numeric formatting; serialization and
4717 deserialization of floats and complex numbers using marshal, pickle and json;
4718 parsing of float and imaginary literals in Python code; Decimal-to-float
4719 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004720
Georg Brandlba83f822010-03-14 09:50:54 +00004721 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4722 providing correctly-rounded strtod and dtoa C functions. This code is
4723 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4724 the C compiler. There may be a small number of platforms on which correct
4725 operation of this code cannot be guaranteed, so the code is not used: notably,
4726 this applies to platforms where the C double format is not IEEE 754 binary64,
4727 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4728 and Python's configure script is unable to determine how to change the FPU
4729 precision. On these platforms conversions use the platform strtod and dtoa,
4730 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004732- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4733 uses the correctly-rounded string <-> float conversions described above (when
4734 available), and so produces correctly rounded results that will display nicely
4735 under the float repr. There are two related small changes: (1) round now
4736 accepts any class with an ``__index__()`` method for its second argument (but
4737 no longer accepts floats for the second argument), and (2) an excessively
4738 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4739 raises an exception.

4966 internal representation of integers, for performance reasons. Base 2**30 is
4967 enabled by default on 64-bit machines. Add --enable-big-digits option to

5154 gives improved memory leak detection when running under Valgrind, while taking
5155 advantage of pymalloc at other times.

6325 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6326 neither __int__ nor __long__, TypeError used to be raised (with a
6327 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6328 struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006525- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6526 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6527 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6528 ``printf`` function, whereas PyString_FromFormat has an independent
6529 implementation and uses "%zd" on all platforms for size_t values.
6530 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006546- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006547 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006548 was correctly parsed but parsing of subsequent arguments failed.
6549
Vinay Sajip35e3b032008-09-01 14:33:59 +00006550- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006551 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6552 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6553 when given a tuple of classes as second argument, were looking up
6554 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6555 type object.
6556
Neal Norwitz18aa3882008-08-24 05:04:52 +00006557- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00006565- Silenced another compiler warning about a used but not defined
6566 function 'stringlib_contains_obj'.
6567
Benjamin Peterson712ee922008-08-24 18:10:20 +00006568- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00006626 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6627 for catch_warnings() also led to an improvement in the raising of a
6628 DeprecationWarning related to warnings.warn_explicit().
6629

6655 without limit.
6656
Benjamin Peterson37346b22008-08-23 20:27:43 +00006657- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006694What's New in Python 2.6 beta 3?
6695================================
6696
Barry Warsaw07a4a382008-08-21 01:15:08 +00006697*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006698
6699Core and Builtins
6700-----------------
6701
Guido van Rossumf8402962008-08-20 15:01:50 +00006702- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6703 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6704 extensions do not automatically benefit from the class attribute
6705 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6706 to their tp_flags field if they care. This is a backwards
6707 compatibility feature; in 3.0, all types will use the cache by
6708 default.
6709
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006710- Keyword arguments can now follow starred arguments. (``f(a, *args,
6711 keyword=23)`` is now valid syntax.)
6712
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006713- ctypes function pointers that are COM methods have a boolean True
6714 value again.
6715
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006716- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6717 by denying s# to parse objects that have a releasebuffer procedure,
6718 and introducing s*.
6719
Georg Brandl1e13ea92008-08-11 09:07:59 +00006720- Issue #3537: Fix an assertion failure when an empty but presized dict
6721 object was stored in the freelist.
6722
Mark Dickinsonb6467572008-08-04 21:30:09 +00006723- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6724 ValueError consistently across platforms.
6725
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006726- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6727 (64bit Unix, for example), unichr() would truncate its argument and return
6728 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6729
Neal Norwitze7d8be82008-07-31 17:17:14 +00006730- Apply security patches from Apple.
6731
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006732- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6733 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6734
Antoine Pitrou92f82162008-07-25 22:22:08 +00006735- Issue #1819: function calls with several named parameters are now on
6736 average 35% faster (as measured by pybench).
6737
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006738- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6739 the python debugger steps into a class statement: the free variables (local
6740 variables defined in an outer scope) would be deleted from the outer scope.
6741
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006742- Issue #2620: Overflow checking when allocating or reallocating memory
6743 was not always being done properly in some python types and extension
6744 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6745 all been updated to perform better checks and places in the code that
6746 would previously leak memory on the error path when such an allocation
6747 failed have been fixed.

6750-------
6751
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006752- Issue #3612: Added some missing basic types in ctypes.wintypes.
6753
Benjamin Petersone977ad42008-08-20 01:42:01 +00006754- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6755 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6756
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006757- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6758 version reported by these tools does not necessarily follow the python
6759 version numbering scheme, so the module is less strict when parsing it.
6760
Nick Coghlanf70385a2008-08-18 12:42:46 +00006761- Issue #2235: Added Py3k warnings for types which will become unhashable
6762 under the stricter __hash__ inheritance rules in 3.0. Several types
6763 which did not meet the rules for hash invariants and were already
6764 unhashable in 3.0 have now been explicitly flagged as unhashable in
6765 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6766 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6767
Brett Cannon88f801d2008-08-18 00:46:22 +00006768- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6769 imported into the module but exposed as part of the module's API.
6770
Brett Cannon7b96f072008-08-18 00:41:11 +00006771- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6772
Brett Cannon46225e72008-08-18 00:36:52 +00006773- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006775- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6776
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006777- Issue #3575: Incremental decoder's decode function now takes bytearray
6778 by using 's*' instead of 't#'.
6779
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006780- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006781 fails unicode conversion on 2nd parameter. (windows only)
6782
Georg Brandl222e2082010-08-01 22:27:39 +00006783- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006784 in a redirect.
6785
Brett Cannonabe423e2008-08-16 21:47:07 +00006786- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006787 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006788
Facundo Batistaeb90b782008-08-16 14:44:07 +00006789- Issue #2776: fixed small issue when handling an URL with double slash
6790 after a 302 response in the case of not going through a proxy.
6791
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006792- Issue #2676: in the email package, content-type parsing was hanging on
6793 pathological input because of quadratic or exponential behaviour of a
6794 regular expression.
6795
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006796- Issue #3476: binary buffered reading through the new "io" library is now
6797 thread-safe.
6798
Brett Cannonbf3157b2008-08-14 05:00:03 +00006799- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6800 since mimetools itself is deprecated. Because modules are cached, all
6801 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6802
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006803- Issue #3134: shutil referenced undefined WindowsError symbol.
6804
Robert Schuppenies14646332008-08-10 11:01:53 +00006805- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6806 menu entries were not deleted.
6807
Brett Cannon83e81842008-08-09 23:30:55 +00006808- Copied the implementation of reduce() to _functools.reduce() to have a
6809 version that did not raise a DeprecationWarning under -3.
6810
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006811- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6812 a MemoryError rather than silently stop the iteration.
6813
Guido van Rossum59ce9012008-08-09 14:55:34 +00006814- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6815 to _sre.compile() will now be rejected. This should not affect anybody
6816 since the re.compile() function never generates invalid re-bytecode.
6817
Skip Montanaroa032bf42008-08-08 22:52:51 +00006818- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6819 upon first access it can be automatically initialized from the csv file if
6820 it wasn't initialized during instantiation.
6821
Brett Cannon3aa2a492008-08-06 22:28:09 +00006822- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6823 the reload() built-in has been removed.
6824
Brett Cannon7e30b672008-08-04 21:52:25 +00006825- Changed code in the following modules/packages to remove warnings raised

6894-----------------
6895
Georg Brandl3e483f62008-07-16 22:57:41 +00006896- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6897 its methods now allow for items objects that can be converted to
6898 an integer using operator.index().
6899
Mark Dickinson64b7e502008-07-16 09:40:03 +00006900- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6901 produced a ValueError instead of giving the correct float.
6902
Eric Smitha5fa5a22008-07-16 00:11:49 +00006903- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6904 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6905
Mark Dickinson7103aa42008-07-15 19:08:33 +00006906- Issue #3008: the float type has a new instance method 'float.hex'
6907 and a new class method 'float.fromhex' to convert floating-point
6908 numbers to and from hexadecimal strings, respectively.
6909
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006910- Issue #2235: __hash__ is once again inherited by default. To allow
6911 collections.Hashable to remain meaningful in the presence of the
6912 default hash implementation (object.__hash__), it is now possible
6913 to explicit block inheritance of hash by setting __hash__=None at
6914 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6915 level.
6916
Nick Coghlanb028f502008-07-13 14:52:36 +00006917- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6918 the parent module cannot be found while performing an absolute import.
6919 This means that an incorrectly defined __package__ attribute will
6920 now only prevent relative imports in that module rather than causing
6921 all imports from that module to fail.
6922
Nick Coghlan14ff9942008-07-08 14:21:42 +00006923- Issue #2517: Allow unicode messages in Exceptions again by correctly

6933 another thread's dictionary.
6934
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006935- Issue #3004: Minor change to slice.indices(): the start and stop
6936 arguments are now treated identically, making the behaviour easier
6937 to describe and understand. For example, slice(None, -10,
6938 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6939 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6940 10, -1).

6983 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006984 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007392 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007393
7394 This is controlled by the configure argument ``--with-universal-archs``:
7395
7396 - ``--with-universal-archs=all``: install 4-way universal
7397
7398 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7399
7400 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7401
7402 This option should be used in combination with ``--enable-universalsdk=``.
7403
7404 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7408
Georg Brandl74a1dea2008-05-28 11:21:39 +00007409- Add ``PyType_Modified()`` as a public API to clear the type cache.
7410
7411- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007412
7413- The PyString functions have been renamed to PyBytes. A batch of
7414 defines were added so that the linker still sees the original
7415 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007453- Issue #1631171: Re-implement the 'warnings' module in C (the
7454 original Python code has been kept as backup). This will allow for
7455 using the 'warning's machinery in such places as the parser where
7456 use of pure Python code is not possible. Both the ``showarning()``
7457 and ``formatwarning()`` gain an optional 'line' argument which is
7458 not called by default for backwards-compatibility reasons. Setting
7459 ``warnings.showwarning()`` to an implementation that lacks support
7460 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007485- The getpass module has been improved on Unix. It now uses /dev/tty
7486 by default and uses stderr instead of stdout. A GetPassWarning is
7487 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007502- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007503 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007523- Issue #2550: The approach used by client/server code for obtaining
7524 ports to listen on in network-oriented tests has been refined in an
7525 effort to facilitate running multiple instances of the entire
7526 regression test suite in parallel without issue.
7527 test_support.bind_port() has been fixed such that it will always
7528 return a unique port -- which wasn't always the case with the
7529 previous implementation, especially if socket options had been set
7530 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7531 new implementation of bind_port() will actually raise an exception
7532 if it is passed an AF_INET/SOCK_STREAM socket with either the
7533 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7534 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7535 the socket it's been passed. This currently only applies to
7536 Windows. This option prevents any other sockets from binding to the
7537 host/port we've bound to, thus removing the possibility of the
7538 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7539 when a second SOCK_STREAM socket binds and accepts to a host/port
7540 that's already been bound by another socket. The optional preferred
7541 port parameter to bind_port() has been removed. Under no
7542 circumstances should tests be hard coding ports!
7543
7544 test_support.find_unused_port() has also been introduced, which will
7545 pass a temporary socket object to bind_port() in order to obtain an
7546 unused port. The temporary socket object is then closed and
7547 deleted, and the port is returned. This method should only be used
7548 for obtaining an unused port in order to pass to an external program
7549 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7550 a parameter to a server-oriented class that doesn't give you direct
7551 access to the underlying socket used.
7552
7553 Finally, test_support.HOST has been introduced, which should be used
7554 for the host argument of any relevant socket calls (i.e. bind and
7555 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007556
7557 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007558 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007559 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7560 test_asynchat and test_socket_ssl.
7561
Georg Brandl3ee81df2008-05-17 18:14:43 +00007562 It is now possible for multiple instances of the regression test
7563 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007842- Added the future_builtins module, which contains hex() and oct().
7843 These are the PEP 3127 version of these functions, designed to be
7844 compatible with the hex() and oct() builtins from Python 3.0. They
7845 differ slightly in their output formats from the existing, unchanged
7846 Python 2.6 builtins. The expected usage of the future_builtins
7847 module is:
7848 from future_builtins import hex, oct
7849
Eric Smith7ef40bf2008-02-20 23:34:22 +00007850- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7851 exponents for exponents with absolute value < 100. Follows C99
7852 standard. This is a change on Windows, which would use 3 digits.
7853 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7854 so that any alterations it does to the resulting string will be
7855 available in stringlib/formatter.h (for float.__format__).
7856
Eric Smith5a3c1352008-02-19 13:21:56 +00007857- Implemented PEP 3101, Advanced String Formatting. This adds a new
7858 builtin format(); a format() method for str and unicode; a
7859 __format__() method to object, str, unicode, int, long, float, and
7860 datetime; the class string.Formatter; and the C API
7861 PyObject_Format().
7862
Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Fixed several potential crashes, all caused by specially crafted
7864 __del__ methods exploiting objects in temporarily inconsistent
7865 state.

7876 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007877
Georg Brandl3ee81df2008-05-17 18:14:43 +00007878- Issue #2045: Fix an infinite recursion triggered when printing a
7879 subclass of collections.defaultdict, if its default_factory is set
7880 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007881
Christian Heimesf75dbef2008-02-08 00:11:31 +00007882- Fixed a minor memory leak in dictobject.c. The content of the free

7891
Georg Brandl3ee81df2008-05-17 18:14:43 +00007892- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7893 calls. Python expected the return type int but the fork familie
7894 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007908- Patch #1473257: generator objects gain a gi_code attribute. This is
7909 the same object as the func_code attribute of the function that
7910 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007911
Georg Brandl3ee81df2008-05-17 18:14:43 +00007912- Issue #1920: "while 0" statements were completely removed by the
7913 compiler, even in the presence of an "else" clause, which is
7914 supposed to be run when the condition is false. Now the compiler
7915 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007916
Guido van Rossumeead05f2008-01-24 18:21:02 +00007917- A few crashers fixed: weakref_in_del.py (issue #1377858);
7918 loosing_dict_ref.py (issue #1303614, test67.py);
7919 borrowed_ref_[34].py (not in tracker).
7920
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007921- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007922 suppressed while an extension is loaded by calling SetErrorMode in
7923 dynload_win.c. The error is still reported properly.
7924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007926 several extension methods and modules do not work without unicode
7927 support.
7928
Georg Brandl26543b12008-01-21 18:36:51 +00007929- Issue #1882: when compiling code from a string, encoding cookies in the
7930 second line of code were not always recognized correctly.
7931
Georg Brandl14404b62008-01-19 19:27:05 +00007932- Issue #1679: "0x" was taken as a valid integer literal.
7933
Georg Brandl6caad7d2008-01-26 14:19:22 +00007934- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007935 added.
7936
Christian Heimesc94e2b52008-01-14 04:13:37 +00007937- sys.float_info / PyFloat_GetInfo: The floating point information
7938 object was converted from a dict to a specialized structseq object.
7939
Georg Brandl3ee81df2008-05-17 18:14:43 +00007940- Patch #1816: Added sys.flags structseq. It exposes the status of
7941 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007942
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943- Objects/structseq.c: Implemented new structseq representation. The
7944 patch makes structseqs (e.g. the return value of os.stat) more
7945 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007946
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947- Patch #1700288: added a type attribute cache that caches method
7948 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007949
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007950- Bug #1776: __import__() no longer accepts filenames on any platform.
7951 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007952
Georg Brandlaed6c662008-01-07 17:25:53 +00007953- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7954
Georg Brandl3ee81df2008-05-17 18:14:43 +00007955- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7956 envvar and sys.dont_write_bytecode attribute. All these can be set
7957 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007958
Georg Brandl3ee81df2008-05-17 18:14:43 +00007959- Improve some exception messages when Windows fails to load an
7960 extension module. Now we get for example '%1 is not a valid Win32
7961 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007962
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007965- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7966 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007967
Christian Heimes0a8143f2007-12-18 23:22:54 +00007968- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969 and INF. float("nan"), float("inf") and float("-inf") now work on
7970 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007971
Georg Brandl3ee81df2008-05-17 18:14:43 +00007972- Compiler now generates simpler and faster code for dictionary
7973 literals. The oparg for BUILD_MAP now indicates an estimated
7974 dictionary size. There is a new opcode, STORE_MAP, for adding
7975 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Issue #1538: Avoid copying string in split/rsplit if the split char
7983 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007984
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007985- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007986 SystemError.
7987
Nick Coghlanef01d822007-12-03 12:55:17 +00007988- PEP 366: Allow explicit relative imports when executing modules
7989 inside packages with the -m switch via a new module level
7990 __package__ attribute.
7991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Issue #1402: Fix a crash on exit, when another thread is still
7993 running, and if the deallocation of its frames somehow calls the
7994 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007995

Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Patch #1739468: Directories and zipfiles containing a __main__.py
8005 file can now be directly executed by passing their name to the
8006 interpreter. The directory/zipfile is automatically inserted as the
8007 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008008
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009- Issue #1265: Fix a problem with sys.settrace, if the tracing
8010 function uses a generator expression when at the same time the
8011 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008012
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008013- sets and frozensets now have an isdisjoint() method.
8014
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008015- optimize the performance of builtin.sum().
8016
Neal Norwitz44f326e2007-10-05 05:29:17 +00008017- Fix warnings found by the new version of the Coverity checker.
8018
Georg Brandl21e99f42010-03-07 15:23:59 +00008019- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8021 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008022
Georg Brandl3ee81df2008-05-17 18:14:43 +00008023- Issue #1686386: Tuple's tp_repr did not take into account the
8024 possibility of having a self-referential tuple, which is possible
8025 from C code. Nor did object's tp_str consider that a type's tp_str
8026 could do something that could lead to an inifinite recursion.
8027 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8028 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008029
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Issue #1164: It was possible to trigger deadlock when using the
8031 'print' statement to write to a file since the GIL was not released
8032 as needed. Now PyObject_Print() does the right thing along with
8033 various tp_print implementations of the built-in types and those in
8034 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008035
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036- Issue #1147: Exceptions were directly allowing string exceptions in
8037 their throw() method even though string exceptions no longer
8038 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008039
Georg Brandl3ee81df2008-05-17 18:14:43 +00008040- Issue #1096: Prevent a segfault from getting the repr of a very
8041 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008042
Brett Cannon1e534b52007-09-07 04:18:30 +00008043- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044 PyObject_Call() never calling back out to Python code to trigger
8045 recursion depth updates/checks. Required the creation of a static
8046 RuntimeError instance in case normalizing an exception put the
8047 recursion check value past its limit. Fixes crashers
8048 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008049
Georg Brandl3ee81df2008-05-17 18:14:43 +00008050- Patch #1031213: Decode source line in SyntaxErrors back to its

8054 with %G.
8055
Georg Brandl3ee81df2008-05-17 18:14:43 +00008056- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00008063- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 __*__ attributes. (Some already existed, e.g., __doc__ and
8065 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008066
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008067- Add -3 option to the interpreter to warn about features that are
8068 deprecated and will be changed/removed in Python 3.0.
8069
Georg Brandl2134e752007-05-21 20:34:16 +00008070- Patch #1686487: you can now pass any mapping after '**' in function
8071 calls.
8072
Collin Winter62903052007-05-18 23:11:24 +00008073- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008074 "except E as target:". This is to provide forwards compatibility
8075 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008076
Brett Cannon229cee22007-05-05 01:34:02 +00008077- Deprecate BaseException.message as per PEP 352.
8078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008080 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008081
Vinay Sajip8549ce32007-05-06 17:53:37 +00008082- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008083 setting a plain string, ie don't expand to single letter identifiers.
8084
Raymond Hettinger13936692007-04-11 18:40:58 +00008085- Request #1191699: Slices can now be pickled.
8086
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008087- Request #1193128: str.translate() now allows a None argument for
8088 translations that only remove characters without re-mapping the
8089 remaining characters.
8090
Georg Brandl5cb76c12007-03-21 09:00:39 +00008091- Patch #1682205: a TypeError while unpacking an iterable is no longer
8092 masked by a generic one with the message "unpack non-sequence".
8093
Neal Norwitzaa754b72007-03-21 06:39:48 +00008094- Remove unused file Python/fmod.c.
8095
Guido van Rossum143b5642007-03-23 04:58:42 +00008096- Bug #1683368: The object.__init__() and object.__new__() methods are
8097 now stricter in rejecting excess arguments. The only time when
8098 either allows excess arguments is when it is not overridden and the
8099 other one is. For backwards compatibility, when both are
8100 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008101 warning later). Also, type.__init__() insists on the same signature
8102 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8105 object to complex using its __complex__() method before falling back
8106 to the __float__() method. Therefore, the functions in the cmath
8107 module now can operate on objects that define a __complex__()
8108 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008109
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110- Patch #1623563: allow __class__ assignment for classes with
8111 __slots__. The old and the new class are still required to have the
8112 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008113

Georg Brandl3ee81df2008-05-17 18:14:43 +00008117- Patch #1462488: Python no longer segfaults when
8118 ``object.__reduce_ex__()`` is called with an object that is faking
8119 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008120
Georg Brandl3ee81df2008-05-17 18:14:43 +00008121- Patch #1680015: Don't modify __slots__ tuple if it contains an

8125
Georg Brandl7b9c5552007-03-12 14:30:05 +00008126- Bug #1678647: write a newline after printing an exception in any
8127 case, even when converting the value to a string failed.
8128
Georg Brandl871f1bc2007-03-12 13:17:36 +00008129- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130 its argument, if it exists. If not, it will work like before. This
8131 allows customizing the output of dir() in the presence of a
8132 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008134- Patch #922167: Python no longer segfaults when faced with infinitely
8135 self-recursive reload() calls (as reported by bug #742342).
8136
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008140- Patch #1491866: change the complex() constructor to allow
8141 parthensized forms. This means complex(repr(x)) now works instead of
8142 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008143
Georg Brandlaa2321b2007-03-07 00:40:28 +00008144- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008145 makes the filenames the warning module prints much more sensible

8652 ".cpp" too.
8653
Facundo Batistad918a652007-04-24 13:54:38 +00008654- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008655 the client's request was successfully received, understood, and
8656 accepted. Now in these cases no error is raised in urllib (issue
8657 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008658

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008665- Added a timeout parameter to the constructor of other protocols
8666 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8667 work started with create_connection() and timeout in httplib, and
8668 closes patch #723312.
8669
Vinay Sajip8549ce32007-05-06 17:53:37 +00008670- Patch #1676823: Added create_connection() to socket.py, which may be
8671 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008672 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008673
Martin v. Löwis0af33882007-03-23 13:27:15 +00008674- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8694
Georg Brandlf66b6032007-03-14 08:27:52 +00008695- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008696 AttributeError instead of an IOError when the server's response
8697 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008698
Georg Brandl3ee81df2008-05-17 18:14:43 +00008699- Patch #957650: "%var%" environment variable references are now
8700 properly expanded in ntpath.expandvars(), also "~user" home
8701 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008702
Georg Brandl3ee81df2008-05-17 18:14:43 +00008703- Patch #1429539: pdb now correctly initializes the __main__ module
8704 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008705 correctly now.
8706
Georg Brandlbad6f192007-03-13 21:32:56 +00008707- The nonobvious commands.getstatus() function is now deprecated.

8713
Georg Brandl3ee81df2008-05-17 18:14:43 +00008714- Patch #1530482: add pydoc.render_doc() which returns the
8715 documentation for a thing instead of paging it to stdout, which
8716 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008717
Georg Brandl3ee81df2008-05-17 18:14:43 +00008718- Patch #1533909: the timeit module now accepts callables in addition

8724 parameter which can be set to False to prevent the default
8725 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008726
Georg Brandl9e6b4702007-03-13 18:15:41 +00008727- Patch #1581073: add a flag to textwrap that prevents the dropping of
8728 whitespace while wrapping.
8729
Georg Brandl92a6bae2007-03-13 17:43:32 +00008730- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008731 are set for invalid interpolation sequences that would lead to
8732 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008733

8746
Georg Brandl94fe3f52007-03-13 09:32:11 +00008747- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008748 field names in its exception message if you try to write a record
8749 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008767

8775 returned string up to the first NUL character.

8786
Georg Brandl3ee81df2008-05-17 18:14:43 +00008787- unittest now verifies more of its assumptions. In particular,
8788 TestCase and TestSuite subclasses (not instances) are no longer
8789 accepted in TestSuite.addTest(). This should cause no
8790 incompatibility since it never made sense with ordinary subclasses
8791 -- the failure just occurred later, with a more cumbersome
8792 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008793

8801 given a unicode argument and os.listdir() returns unicode filenames.
8802
Georg Brandl3ee81df2008-05-17 18:14:43 +00008803- Patch #1673619: setup.py identifies extension modules it doesn't

8805 build.

9157 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9158 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009174- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175 time so that opening a database previously created with the DB_DUP
9176 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9177 opens. Specifically: dictionary assignment to a DB object will
9178 replace all values for a given key when the database allows
9179 duplicate values. DB users should use DB.put(k, v) when they want
9180 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009181

9187 characters with ASCII value less than 32. Also, it correctly quotes
9188 dots only if they occur on a single line, as opposed to the previous
9189 behavior of quoting dots if they are the second character of any
9190 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009191
