1603 In particular, fix extension module build failures when trying to use
1604 32-bit-only installer Pythons on systems with Xcode 4 (currently
1605 OS X 10.8, 10.7, and optionally 10.6).
1606 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1607 * Since Xcode 4 removes ppc support, extension module builds now
1608 check for ppc compiler support and by default remove ppc and
1609 ppc64 archs when they are not available.
1610 * Extension module builds now revert to using system installed
1611 headers and libs (/usr and /System/Library) if the SDK used
1612 to build the interpreter is not installed or has moved.
1613 * Try to avoid building extension modules with deprecated
1614 and problematic Apple llvm-gcc compiler. If original compiler
1615 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002039- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002040 has left two versions of customize_compiler, the original in
2041 distutils.sysconfig and another copy in distutils.ccompiler, with some
2042 parts of distutils calling one and others using the other.
2043 Complete the revert back to only having one in distutils.sysconfig as
2044 is the case in 3.x.
2045
Ned Deily0d0ea482012-02-10 12:59:06 +01002046- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2047 Distutils-based packages with C extension modules may fail because
2048 Apple has removed gcc-4.2, the version used to build python.org
2049 64-bit/32-bit Pythons. If the user does not explicitly override
2050 the default C compiler by setting the CC environment variable,
2051 Distutils will now attempt to compile extension modules with clang
2052 if gcc-4.2 is required but not found. Also as a convenience, if
2053 the user does explicitly set CC, substitute its value as the default
2054 compiler in the Distutils LDSHARED configuration variable for OS X.
2055 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2056 SDK, neither of which are available in Xcode 4. This change does not
2057 attempt to override settings to support their use with Xcode 4.)

Ezio Melotti302ad8d2013-01-19 19:44:58 +02002311 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002312 deployment target only in the environment of each build subprocess. It is
2313 still possible to globally override the default by setting
2314 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2315 greater or equal to the default value, the value with which the interpreter
2316 was built.

3791
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003792- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3793 start byte and the continuation byte(s) are now considered invalid, instead
3794 of the number of bytes specified by the start byte.
3795 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3796 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3797 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3798 Previous versions returned a single u'\ufffd'.
3799
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003800- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003801 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3802 arises from the "Overriding __eq__ blocks inheritance ..." warning
3803 when turned into an exception: in this case the exception simply
3804 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003805
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003806- Issue #8748: Fix two issues with comparisons between complex and integer
3807 objects. (1) The comparison could incorrectly return True in some cases
3808 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3809 (2) The comparison raised an OverflowError for large integers, leading
3810 to unpredictable exceptions when combining integers and complex objects
3811 in sets or dicts.
3812
Mark Dickinson81336372010-05-30 12:12:25 +00003813- Issue #5211: Implicit coercion for the complex type is now completely
3814 removed. (Coercion for arithmetic operations was already removed in 2.7
3815 alpha 4, but coercion for rich comparisons was accidentally left in.)
3816
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003817- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3818 and error handler, instead of writing to the C stderr file in utf-8
3819
Georg Brandlfee0f442010-05-22 21:26:21 +00003820- Issue #7902: When using explicit relative import syntax, don't try implicit
3821 relative import semantics.

3833 of the interpreter to set sys.argv without also modifying sys.path. This

3951 non-float non-integer argument is now converted to an integer (if possible)
3952 using its __int__ method. Previously, only small arguments were treated this

4179
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004180- Issue #8329: Don't return the same lists from select.select when no fds are
4181 changed.
4182
Georg Brandlfee0f442010-05-22 21:26:21 +00004183- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00004193- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4194 with a non-empty format string. This is an effort to future-proof user
4195 code. If a derived class does not currently implement __format__ but later
4196 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004197 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004198 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00004569- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00004570 thread could raise an incorrect RuntimeError about not holding the import
4571 lock. The import lock is now reinitialized after fork.

Georg Brandlba83f822010-03-14 09:50:54 +00004592- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004593 is run with the -OO flag. Tests requiring docstrings are skipped.
4594
Georg Brandlba83f822010-03-14 09:50:54 +00004595- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4596 now also used by regrtest to run all the tests in a temporary directory. The
4597 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4598 Xicluna who helped with the patch.

4615 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004616 library would return a bogus result; on Solaris, it was possible to crash the
4617 interpreter. Patch by Stefan Krah.

4628 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00004629
Georg Brandlba83f822010-03-14 09:50:54 +00004630- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4631 and add the additional members returned in an OSVERSIONINFOEX structure. The
4632 new members are service_pack_major, service_pack_minor, suite_mask, and
4633 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00004634
Georg Brandlba83f822010-03-14 09:50:54 +00004635- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4636 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4637 returning NULL. The macro now returns a statically allocated empty string
4638 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00004639
Antoine Pitrou64672132010-01-13 07:55:48 +00004640- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00004647 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4648 strings,
4649 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4650 numeric strings corresponding to subnormal values,
4651 (3) a memory leak for some values large enough to cause overflow, and
4652 (4) a number of flaws that could lead to incorrectly rounded results.
4653
4654- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
4655 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00004656

4668
R. David Murray63e4fd72010-02-10 22:42:04 +00004669- Issue #7835: shelve should no longer produce mysterious warnings during
4670 interpreter shutdown.
4671
Georg Brandlba83f822010-03-14 09:50:54 +00004672- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4673 XML processing instructions and comments. These raw characters are allowed
4674 by the XML specification, and are necessary when outputting e.g. PHP code in
4675 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +00004682
Antoine Pitroud840e512010-02-04 20:20:18 +00004683- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004684 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004685 Also, raise ValueError rather than TypeError when an unknown TIPC address
4686 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004690- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004691 file position when calling `truncate()`. It would previously change the file
4692 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004693 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4694
Georg Brandlba83f822010-03-14 09:50:54 +00004695- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4696 class used to represent files stored inside an archive. The new
4697 implementation is significantly faster and can be wrapped in a
4698 ``io.BufferedReader`` object for more speedups. It also solves an issue
4699 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4700 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004709
Georg Brandlba83f822010-03-14 09:50:54 +00004710- Issue #7748: Since unicode values are supported for some metadata options in
4711 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4712 encoded string for them. This ensures that the upload and register commands
4713 send the correct values to PyPI without any error.

4789
Georg Brandlba83f822010-03-14 09:50:54 +00004790- The ``__complex__()`` method is now looked up on the class of instances to
4791 make it consistent with other special methods.

4795
Mark Dickinson1b34d252010-01-01 17:27:30 +00004796- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004797 DeprecationWarning when passed a float argument where an integer was expected.
4798 These functions and methods now raise TypeError instead. The majority of the
4799 effects of this change are in the extension modules, but some core functions
4800 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4801 and many unicode/str methods.

4815 of integers: the result of a/b is now correctly rounded for ints a and b (at
4816 least on IEEE 754 platforms), and in particular does not depend on the
4817 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004826 These executables now work properly with the arch(1) command: ``arch -ppc

4974 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004983- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4984 decimal string that's guaranteed to round back to x under correct rounding
4985 (with round-half-to-even rounding mode). Previously it gave a string based on
4986 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4987 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4988 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004990- Issue #7117: On almost all platforms: float-to-string and string-to-float
4991 conversions within Python are now correctly rounded. Places these conversions
4992 occur include: str for floats and complex numbers; the float and complex
4993 constructors; old-style and new-style numeric formatting; serialization and
4994 deserialization of floats and complex numbers using marshal, pickle and json;
4995 parsing of float and imaginary literals in Python code; Decimal-to-float
4996 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004997
Georg Brandlba83f822010-03-14 09:50:54 +00004998 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4999 providing correctly-rounded strtod and dtoa C functions. This code is
5000 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5001 the C compiler. There may be a small number of platforms on which correct
5002 operation of this code cannot be guaranteed, so the code is not used: notably,
5003 this applies to platforms where the C double format is not IEEE 754 binary64,
5004 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5005 and Python's configure script is unable to determine how to change the FPU
5006 precision. On these platforms conversions use the platform strtod and dtoa,
5007 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005009- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5010 uses the correctly-rounded string <-> float conversions described above (when
5011 available), and so produces correctly rounded results that will display nicely
5012 under the float repr. There are two related small changes: (1) round now
5013 accepts any class with an ``__index__()`` method for its second argument (but
5014 no longer accepts floats for the second argument), and (2) an excessively
5015 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5016 raises an exception.

5243 internal representation of integers, for performance reasons. Base 2**30 is
5244 enabled by default on 64-bit machines. Add --enable-big-digits option to
5245 configure, which overrides the default. Add sys.long_info structseq to

5395 this code path is really executed because I cannot move to such directory on

5431 gives improved memory leak detection when running under Valgrind, while taking
5432 advantage of pymalloc at other times.

6602 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6603 neither __int__ nor __long__, TypeError used to be raised (with a

6804 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6805 ``printf`` function, whereas PyString_FromFormat has an independent
6806 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006823- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006824 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006825 was correctly parsed but parsing of subsequent arguments failed.
6826
Vinay Sajip35e3b032008-09-01 14:33:59 +00006827- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006828 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6829 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6830 when given a tuple of classes as second argument, were looking up
6831 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6832 type object.
6833
Neal Norwitz18aa3882008-08-24 05:04:52 +00006834- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00006842- Silenced another compiler warning about a used but not defined
6843 function 'stringlib_contains_obj'.
6844
Benjamin Peterson712ee922008-08-24 18:10:20 +00006845- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00006903 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6904 for catch_warnings() also led to an improvement in the raising of a
6905 DeprecationWarning related to warnings.warn_explicit().
6906

6932 without limit.
6933
Benjamin Peterson37346b22008-08-23 20:27:43 +00006934- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006971What's New in Python 2.6 beta 3?
6972================================
6973
Barry Warsaw07a4a382008-08-21 01:15:08 +00006974*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006975
6976Core and Builtins
6977-----------------
6978
Guido van Rossumf8402962008-08-20 15:01:50 +00006979- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6980 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6981 extensions do not automatically benefit from the class attribute
6982 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6983 to their tp_flags field if they care. This is a backwards
6984 compatibility feature; in 3.0, all types will use the cache by
6985 default.
6986
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006987- Keyword arguments can now follow starred arguments. (``f(a, *args,
6988 keyword=23)`` is now valid syntax.)
6989
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006990- ctypes function pointers that are COM methods have a boolean True
6991 value again.
6992
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006993- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6994 by denying s# to parse objects that have a releasebuffer procedure,
6995 and introducing s*.
6996
Georg Brandl1e13ea92008-08-11 09:07:59 +00006997- Issue #3537: Fix an assertion failure when an empty but presized dict
6998 object was stored in the freelist.
6999
Mark Dickinsonb6467572008-08-04 21:30:09 +00007000- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7001 ValueError consistently across platforms.
7002
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007003- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7004 (64bit Unix, for example), unichr() would truncate its argument and return
7005 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7006
Neal Norwitze7d8be82008-07-31 17:17:14 +00007007- Apply security patches from Apple.
7008
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007009- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7010 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7011
Antoine Pitrou92f82162008-07-25 22:22:08 +00007012- Issue #1819: function calls with several named parameters are now on
7013 average 35% faster (as measured by pybench).
7014
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007015- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7016 the python debugger steps into a class statement: the free variables (local
7017 variables defined in an outer scope) would be deleted from the outer scope.
7018
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007019- Issue #2620: Overflow checking when allocating or reallocating memory
7020 was not always being done properly in some python types and extension
7021 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7022 all been updated to perform better checks and places in the code that
7023 would previously leak memory on the error path when such an allocation
7024 failed have been fixed.

7027-------
7028
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007029- Issue #3612: Added some missing basic types in ctypes.wintypes.
7030
Benjamin Petersone977ad42008-08-20 01:42:01 +00007031- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7032 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7033
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007034- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7035 version reported by these tools does not necessarily follow the python
7036 version numbering scheme, so the module is less strict when parsing it.
7037
Nick Coghlanf70385a2008-08-18 12:42:46 +00007038- Issue #2235: Added Py3k warnings for types which will become unhashable
7039 under the stricter __hash__ inheritance rules in 3.0. Several types
7040 which did not meet the rules for hash invariants and were already
7041 unhashable in 3.0 have now been explicitly flagged as unhashable in
7042 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7043 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7044
Brett Cannon88f801d2008-08-18 00:46:22 +00007045- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7046 imported into the module but exposed as part of the module's API.
7047
Brett Cannon7b96f072008-08-18 00:41:11 +00007048- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7049
Brett Cannon46225e72008-08-18 00:36:52 +00007050- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007052- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7053
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007054- Issue #3575: Incremental decoder's decode function now takes bytearray
7055 by using 's*' instead of 't#'.
7056
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007057- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007058 fails unicode conversion on 2nd parameter. (windows only)
7059
Georg Brandl222e2082010-08-01 22:27:39 +00007060- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007061 in a redirect.
7062
Brett Cannonabe423e2008-08-16 21:47:07 +00007063- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007064 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007065
Facundo Batistaeb90b782008-08-16 14:44:07 +00007066- Issue #2776: fixed small issue when handling an URL with double slash
7067 after a 302 response in the case of not going through a proxy.
7068
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007069- Issue #2676: in the email package, content-type parsing was hanging on
7070 pathological input because of quadratic or exponential behaviour of a
7071 regular expression.
7072
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007073- Issue #3476: binary buffered reading through the new "io" library is now
7074 thread-safe.
7075
Brett Cannonbf3157b2008-08-14 05:00:03 +00007076- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7077 since mimetools itself is deprecated. Because modules are cached, all
7078 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7079
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007080- Issue #3134: shutil referenced undefined WindowsError symbol.
7081
Robert Schuppenies14646332008-08-10 11:01:53 +00007082- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7083 menu entries were not deleted.
7084
Brett Cannon83e81842008-08-09 23:30:55 +00007085- Copied the implementation of reduce() to _functools.reduce() to have a
7086 version that did not raise a DeprecationWarning under -3.
7087
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007088- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7089 a MemoryError rather than silently stop the iteration.
7090
Guido van Rossum59ce9012008-08-09 14:55:34 +00007091- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7092 to _sre.compile() will now be rejected. This should not affect anybody
7093 since the re.compile() function never generates invalid re-bytecode.
7094
Skip Montanaroa032bf42008-08-08 22:52:51 +00007095- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7096 upon first access it can be automatically initialized from the csv file if
7097 it wasn't initialized during instantiation.
7098
Brett Cannon3aa2a492008-08-06 22:28:09 +00007099- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7100 the reload() built-in has been removed.
7101
Brett Cannon7e30b672008-08-04 21:52:25 +00007102- Changed code in the following modules/packages to remove warnings raised

7171-----------------
7172
Georg Brandl3e483f62008-07-16 22:57:41 +00007173- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7174 its methods now allow for items objects that can be converted to
7175 an integer using operator.index().
7176
Mark Dickinson64b7e502008-07-16 09:40:03 +00007177- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7178 produced a ValueError instead of giving the correct float.
7179
Eric Smitha5fa5a22008-07-16 00:11:49 +00007180- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7181 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7182
Mark Dickinson7103aa42008-07-15 19:08:33 +00007183- Issue #3008: the float type has a new instance method 'float.hex'
7184 and a new class method 'float.fromhex' to convert floating-point
7185 numbers to and from hexadecimal strings, respectively.
7186
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007187- Issue #2235: __hash__ is once again inherited by default. To allow
7188 collections.Hashable to remain meaningful in the presence of the
7189 default hash implementation (object.__hash__), it is now possible
7190 to explicit block inheritance of hash by setting __hash__=None at
7191 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7192 level.
7193
Nick Coghlanb028f502008-07-13 14:52:36 +00007194- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7195 the parent module cannot be found while performing an absolute import.
7196 This means that an incorrectly defined __package__ attribute will
7197 now only prevent relative imports in that module rather than causing
7198 all imports from that module to fail.
7199
Nick Coghlan14ff9942008-07-08 14:21:42 +00007200- Issue #2517: Allow unicode messages in Exceptions again by correctly

7210 another thread's dictionary.
7211
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007212- Issue #3004: Minor change to slice.indices(): the start and stop
7213 arguments are now treated identically, making the behaviour easier
7214 to describe and understand. For example, slice(None, -10,
7215 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7216 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7217 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007219- Issue #3219: Calling a function with repeated keyword arguments,

7260 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007261 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007262 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007278- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007669 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007670
7671 This is controlled by the configure argument ``--with-universal-archs``:
7672
7673 - ``--with-universal-archs=all``: install 4-way universal
7674
7675 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7676
7677 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7678
7679 This option should be used in combination with ``--enable-universalsdk=``.
7680
7681 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7685
Georg Brandl74a1dea2008-05-28 11:21:39 +00007686- Add ``PyType_Modified()`` as a public API to clear the type cache.
7687
7688- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007689
7690- The PyString functions have been renamed to PyBytes. A batch of
7691 defines were added so that the linker still sees the original
7692 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007730- Issue #1631171: Re-implement the 'warnings' module in C (the
7731 original Python code has been kept as backup). This will allow for
7732 using the 'warning's machinery in such places as the parser where
7733 use of pure Python code is not possible. Both the ``showarning()``
7734 and ``formatwarning()`` gain an optional 'line' argument which is
7735 not called by default for backwards-compatibility reasons. Setting
7736 ``warnings.showwarning()`` to an implementation that lacks support
7737 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007762- The getpass module has been improved on Unix. It now uses /dev/tty
7763 by default and uses stderr instead of stdout. A GetPassWarning is
7764 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007780 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007800- Issue #2550: The approach used by client/server code for obtaining
7801 ports to listen on in network-oriented tests has been refined in an
7802 effort to facilitate running multiple instances of the entire
7803 regression test suite in parallel without issue.
7804 test_support.bind_port() has been fixed such that it will always
7805 return a unique port -- which wasn't always the case with the
7806 previous implementation, especially if socket options had been set
7807 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7808 new implementation of bind_port() will actually raise an exception
7809 if it is passed an AF_INET/SOCK_STREAM socket with either the
7810 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7811 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7812 the socket it's been passed. This currently only applies to
7813 Windows. This option prevents any other sockets from binding to the
7814 host/port we've bound to, thus removing the possibility of the
7815 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7816 when a second SOCK_STREAM socket binds and accepts to a host/port
7817 that's already been bound by another socket. The optional preferred
7818 port parameter to bind_port() has been removed. Under no
7819 circumstances should tests be hard coding ports!
7820
7821 test_support.find_unused_port() has also been introduced, which will
7822 pass a temporary socket object to bind_port() in order to obtain an
7823 unused port. The temporary socket object is then closed and
7824 deleted, and the port is returned. This method should only be used
7825 for obtaining an unused port in order to pass to an external program
7826 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7827 a parameter to a server-oriented class that doesn't give you direct
7828 access to the underlying socket used.
7829
7830 Finally, test_support.HOST has been introduced, which should be used
7831 for the host argument of any relevant socket calls (i.e. bind and
7832 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007833
7834 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007835 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007836 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7837 test_asynchat and test_socket_ssl.
7838
Georg Brandl3ee81df2008-05-17 18:14:43 +00007839 It is now possible for multiple instances of the regression test
7840 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008119- Added the future_builtins module, which contains hex() and oct().
8120 These are the PEP 3127 version of these functions, designed to be
8121 compatible with the hex() and oct() builtins from Python 3.0. They
8122 differ slightly in their output formats from the existing, unchanged
8123 Python 2.6 builtins. The expected usage of the future_builtins
8124 module is:
8125 from future_builtins import hex, oct
8126
Eric Smith7ef40bf2008-02-20 23:34:22 +00008127- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8128 exponents for exponents with absolute value < 100. Follows C99
8129 standard. This is a change on Windows, which would use 3 digits.
8130 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8131 so that any alterations it does to the resulting string will be
8132 available in stringlib/formatter.h (for float.__format__).
8133
Eric Smith5a3c1352008-02-19 13:21:56 +00008134- Implemented PEP 3101, Advanced String Formatting. This adds a new
8135 builtin format(); a format() method for str and unicode; a
8136 __format__() method to object, str, unicode, int, long, float, and
8137 datetime; the class string.Formatter; and the C API
8138 PyObject_Format().
8139
Georg Brandl3ee81df2008-05-17 18:14:43 +00008140- Fixed several potential crashes, all caused by specially crafted
8141 __del__ methods exploiting objects in temporarily inconsistent
8142 state.

8153 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008154
Georg Brandl3ee81df2008-05-17 18:14:43 +00008155- Issue #2045: Fix an infinite recursion triggered when printing a
8156 subclass of collections.defaultdict, if its default_factory is set
8157 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008158
Christian Heimesf75dbef2008-02-08 00:11:31 +00008159- Fixed a minor memory leak in dictobject.c. The content of the free

8168
Georg Brandl3ee81df2008-05-17 18:14:43 +00008169- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8170 calls. Python expected the return type int but the fork familie
8171 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008185- Patch #1473257: generator objects gain a gi_code attribute. This is
8186 the same object as the func_code attribute of the function that
8187 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008188
Georg Brandl3ee81df2008-05-17 18:14:43 +00008189- Issue #1920: "while 0" statements were completely removed by the
8190 compiler, even in the presence of an "else" clause, which is
8191 supposed to be run when the condition is false. Now the compiler
8192 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008193
Guido van Rossumeead05f2008-01-24 18:21:02 +00008194- A few crashers fixed: weakref_in_del.py (issue #1377858);
8195 loosing_dict_ref.py (issue #1303614, test67.py);
8196 borrowed_ref_[34].py (not in tracker).
8197
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008198- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008199 suppressed while an extension is loaded by calling SetErrorMode in
8200 dynload_win.c. The error is still reported properly.
8201
Georg Brandl3ee81df2008-05-17 18:14:43 +00008202- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008203 several extension methods and modules do not work without unicode
8204 support.
8205
Georg Brandl26543b12008-01-21 18:36:51 +00008206- Issue #1882: when compiling code from a string, encoding cookies in the
8207 second line of code were not always recognized correctly.
8208
Georg Brandl14404b62008-01-19 19:27:05 +00008209- Issue #1679: "0x" was taken as a valid integer literal.
8210
Georg Brandl6caad7d2008-01-26 14:19:22 +00008211- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008212 added.
8213
Christian Heimesc94e2b52008-01-14 04:13:37 +00008214- sys.float_info / PyFloat_GetInfo: The floating point information
8215 object was converted from a dict to a specialized structseq object.
8216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217- Patch #1816: Added sys.flags structseq. It exposes the status of
8218 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008219
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220- Objects/structseq.c: Implemented new structseq representation. The
8221 patch makes structseqs (e.g. the return value of os.stat) more
8222 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- Patch #1700288: added a type attribute cache that caches method
8225 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008226
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008227- Bug #1776: __import__() no longer accepts filenames on any platform.
8228 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008229
Georg Brandlaed6c662008-01-07 17:25:53 +00008230- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8233 envvar and sys.dont_write_bytecode attribute. All these can be set
8234 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008235
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236- Improve some exception messages when Windows fails to load an
8237 extension module. Now we get for example '%1 is not a valid Win32
8238 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008239
Georg Brandl3ee81df2008-05-17 18:14:43 +00008240- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8243 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008244
Christian Heimes0a8143f2007-12-18 23:22:54 +00008245- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246 and INF. float("nan"), float("inf") and float("-inf") now work on
8247 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Compiler now generates simpler and faster code for dictionary
8250 literals. The oparg for BUILD_MAP now indicates an estimated
8251 dictionary size. There is a new opcode, STORE_MAP, for adding
8252 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008253
Georg Brandl3ee81df2008-05-17 18:14:43 +00008254- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Issue #1538: Avoid copying string in split/rsplit if the split char
8260 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008261
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008262- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008263 SystemError.
8264
Nick Coghlanef01d822007-12-03 12:55:17 +00008265- PEP 366: Allow explicit relative imports when executing modules
8266 inside packages with the -m switch via a new module level
8267 __package__ attribute.
8268
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269- Issue #1402: Fix a crash on exit, when another thread is still
8270 running, and if the deallocation of its frames somehow calls the
8271 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008272

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008276 attribute of an empty cell object.
8277
Georg Brandl3ee81df2008-05-17 18:14:43 +00008278- Issue #1460: The utf-7 incremental decoder did not accept truncated
8279 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Patch #1739468: Directories and zipfiles containing a __main__.py
8282 file can now be directly executed by passing their name to the
8283 interpreter. The directory/zipfile is automatically inserted as the
8284 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008285
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286- Issue #1265: Fix a problem with sys.settrace, if the tracing
8287 function uses a generator expression when at the same time the
8288 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008289
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008290- sets and frozensets now have an isdisjoint() method.
8291
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008292- optimize the performance of builtin.sum().
8293
Neal Norwitz44f326e2007-10-05 05:29:17 +00008294- Fix warnings found by the new version of the Coverity checker.
8295
Georg Brandl21e99f42010-03-07 15:23:59 +00008296- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008297 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8298 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008299
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Issue #1686386: Tuple's tp_repr did not take into account the
8301 possibility of having a self-referential tuple, which is possible
8302 from C code. Nor did object's tp_str consider that a type's tp_str
8303 could do something that could lead to an inifinite recursion.
8304 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8305 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008306
Georg Brandl3ee81df2008-05-17 18:14:43 +00008307- Issue #1164: It was possible to trigger deadlock when using the
8308 'print' statement to write to a file since the GIL was not released
8309 as needed. Now PyObject_Print() does the right thing along with
8310 various tp_print implementations of the built-in types and those in
8311 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008312
Georg Brandl3ee81df2008-05-17 18:14:43 +00008313- Issue #1147: Exceptions were directly allowing string exceptions in
8314 their throw() method even though string exceptions no longer
8315 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008316
Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Issue #1096: Prevent a segfault from getting the repr of a very
8318 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008319
Brett Cannon1e534b52007-09-07 04:18:30 +00008320- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008321 PyObject_Call() never calling back out to Python code to trigger
8322 recursion depth updates/checks. Required the creation of a static
8323 RuntimeError instance in case normalizing an exception put the
8324 recursion check value past its limit. Fixes crashers
8325 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008326
Georg Brandl3ee81df2008-05-17 18:14:43 +00008327- Patch #1031213: Decode source line in SyntaxErrors back to its

8331 with %G.
8332
Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Prevent expandtabs() on string and unicode objects from causing a
8334 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008335

Neal Norwitz0ac60192007-05-27 04:08:54 +00008340- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008341 __*__ attributes. (Some already existed, e.g., __doc__ and
8342 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008343
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008344- Add -3 option to the interpreter to warn about features that are
8345 deprecated and will be changed/removed in Python 3.0.
8346
Georg Brandl2134e752007-05-21 20:34:16 +00008347- Patch #1686487: you can now pass any mapping after '**' in function
8348 calls.
8349
Collin Winter62903052007-05-18 23:11:24 +00008350- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351 "except E as target:". This is to provide forwards compatibility
8352 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008353
Brett Cannon229cee22007-05-05 01:34:02 +00008354- Deprecate BaseException.message as per PEP 352.
8355
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008357 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008358
Vinay Sajip8549ce32007-05-06 17:53:37 +00008359- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008360 setting a plain string, ie don't expand to single letter identifiers.
8361
Raymond Hettinger13936692007-04-11 18:40:58 +00008362- Request #1191699: Slices can now be pickled.
8363
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008364- Request #1193128: str.translate() now allows a None argument for
8365 translations that only remove characters without re-mapping the
8366 remaining characters.
8367
Georg Brandl5cb76c12007-03-21 09:00:39 +00008368- Patch #1682205: a TypeError while unpacking an iterable is no longer
8369 masked by a generic one with the message "unpack non-sequence".
8370
Neal Norwitzaa754b72007-03-21 06:39:48 +00008371- Remove unused file Python/fmod.c.
8372
Guido van Rossum143b5642007-03-23 04:58:42 +00008373- Bug #1683368: The object.__init__() and object.__new__() methods are
8374 now stricter in rejecting excess arguments. The only time when
8375 either allows excess arguments is when it is not overridden and the
8376 other one is. For backwards compatibility, when both are
8377 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008378 warning later). Also, type.__init__() insists on the same signature
8379 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008380
Georg Brandl3ee81df2008-05-17 18:14:43 +00008381- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8382 object to complex using its __complex__() method before falling back
8383 to the __float__() method. Therefore, the functions in the cmath
8384 module now can operate on objects that define a __complex__()
8385 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008386
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387- Patch #1623563: allow __class__ assignment for classes with
8388 __slots__. The old and the new class are still required to have the
8389 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008390
Georg Brandl3ee81df2008-05-17 18:14:43 +00008391- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00008394- Patch #1462488: Python no longer segfaults when
8395 ``object.__reduce_ex__()`` is called with an object that is faking
8396 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008397
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008401- Patch #1444529: the builtin compile() now accepts keyword arguments.
8402
Georg Brandl7b9c5552007-03-12 14:30:05 +00008403- Bug #1678647: write a newline after printing an exception in any
8404 case, even when converting the value to a string failed.
8405
Georg Brandl871f1bc2007-03-12 13:17:36 +00008406- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008407 its argument, if it exists. If not, it will work like before. This
8408 allows customizing the output of dir() in the presence of a
8409 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008411- Patch #922167: Python no longer segfaults when faced with infinitely
8412 self-recursive reload() calls (as reported by bug #742342).
8413
Georg Brandl3ee81df2008-05-17 18:14:43 +00008414- Patch #1675981: remove unreachable code from ``type.__new__()``
8415 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008417- Patch #1491866: change the complex() constructor to allow
8418 parthensized forms. This means complex(repr(x)) now works instead of
8419 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008420
Georg Brandlaa2321b2007-03-07 00:40:28 +00008421- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008422 makes the filenames the warning module prints much more sensible

8930
Facundo Batistad918a652007-04-24 13:54:38 +00008931- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008932 the client's request was successfully received, understood, and
8933 accepted. Now in these cases no error is raised in urllib (issue
8934 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008935

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008942- Added a timeout parameter to the constructor of other protocols
8943 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8944 work started with create_connection() and timeout in httplib, and
8945 closes patch #723312.
8946
Vinay Sajip8549ce32007-05-06 17:53:37 +00008947- Patch #1676823: Added create_connection() to socket.py, which may be
8948 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008949 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008950
Martin v. Löwis0af33882007-03-23 13:27:15 +00008951- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8971
Georg Brandlf66b6032007-03-14 08:27:52 +00008972- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008973 AttributeError instead of an IOError when the server's response
8974 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008975
Georg Brandl3ee81df2008-05-17 18:14:43 +00008976- Patch #957650: "%var%" environment variable references are now
8977 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008979
Georg Brandl3ee81df2008-05-17 18:14:43 +00008980- Patch #1429539: pdb now correctly initializes the __main__ module
8981 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008982 correctly now.
8983
Georg Brandlbad6f192007-03-13 21:32:56 +00008984- The nonobvious commands.getstatus() function is now deprecated.

8990
Georg Brandl3ee81df2008-05-17 18:14:43 +00008991- Patch #1530482: add pydoc.render_doc() which returns the
8992 documentation for a thing instead of paging it to stdout, which
8993 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008994
Georg Brandl3ee81df2008-05-17 18:14:43 +00008995- Patch #1533909: the timeit module now accepts callables in addition

9001 parameter which can be set to False to prevent the default
9002 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00009003
Georg Brandl9e6b4702007-03-13 18:15:41 +00009004- Patch #1581073: add a flag to textwrap that prevents the dropping of
9005 whitespace while wrapping.
9006
Georg Brandl92a6bae2007-03-13 17:43:32 +00009007- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009008 are set for invalid interpolation sequences that would lead to
9009 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009010

Georg Brandl3ee81df2008-05-17 18:14:43 +00009025 field names in its exception message if you try to write a record
9026 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00009044

9052 returned string up to the first NUL character.
9053

9063
Georg Brandl3ee81df2008-05-17 18:14:43 +00009064- unittest now verifies more of its assumptions. In particular,
9065 TestCase and TestSuite subclasses (not instances) are no longer
9066 accepted in TestSuite.addTest(). This should cause no
9067 incompatibility since it never made sense with ordinary subclasses
9068 -- the failure just occurred later, with a more cumbersome
9069 exception.

9078 given a unicode argument and os.listdir() returns unicode filenames.
9079
Georg Brandl3ee81df2008-05-17 18:14:43 +00009080- Patch #1673619: setup.py identifies extension modules it doesn't

9082 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009451- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009452 time so that opening a database previously created with the DB_DUP
9453 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9454 opens. Specifically: dictionary assignment to a DB object will
9455 replace all values for a given key when the database allows
9456 duplicate values. DB users should use DB.put(k, v) when they want
9457 to store duplicates; not DB[k] = v.

9464 characters with ASCII value less than 32. Also, it correctly quotes
9465 dots only if they occur on a single line, as opposed to the previous
9466 behavior of quoting dots if they are the second character of any
9467 line.
