16 is modified during the lifetime of the Python process after zipimport has
17 already cached the zip's table of contents we detect this and recover

30 contains a frame, and the frame kept a reference to the Python state of the

1618 In particular, fix extension module build failures when trying to use
1619 32-bit-only installer Pythons on systems with Xcode 4 (currently
1620 OS X 10.8, 10.7, and optionally 10.6).
1621 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1622 * Since Xcode 4 removes ppc support, extension module builds now
1623 check for ppc compiler support and by default remove ppc and
1624 ppc64 archs when they are not available.
1625 * Extension module builds now revert to using system installed
1626 headers and libs (/usr and /System/Library) if the SDK used
1627 to build the interpreter is not installed or has moved.
1628 * Try to avoid building extension modules with deprecated
1629 and problematic Apple llvm-gcc compiler. If original compiler
1630 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002054- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002055 has left two versions of customize_compiler, the original in
2056 distutils.sysconfig and another copy in distutils.ccompiler, with some
2057 parts of distutils calling one and others using the other.
2058 Complete the revert back to only having one in distutils.sysconfig as
2059 is the case in 3.x.
2060
Ned Deily0d0ea482012-02-10 12:59:06 +01002061- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2062 Distutils-based packages with C extension modules may fail because
2063 Apple has removed gcc-4.2, the version used to build python.org
2064 64-bit/32-bit Pythons. If the user does not explicitly override
2065 the default C compiler by setting the CC environment variable,
2066 Distutils will now attempt to compile extension modules with clang
2067 if gcc-4.2 is required but not found. Also as a convenience, if
2068 the user does explicitly set CC, substitute its value as the default
2069 compiler in the Distutils LDSHARED configuration variable for OS X.
2070 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2071 SDK, neither of which are available in Xcode 4. This change does not
2072 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002322- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2323 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2324 interpreter process. This could cause failures in non-Distutils subprocesses
2325 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002326 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002327 deployment target only in the environment of each build subprocess. It is
2328 still possible to globally override the default by setting
2329 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2330 greater or equal to the default value, the value with which the interpreter
2331 was built.

2361 the ticker doesn't have to wind down to zero from the old starting point
2362 before the new interval takes effect. And if the user increases the
2363 interval, it makes sure the new limit takes effect right away rather have an
2364 early task switch before recognizing the new interval.

3805-----------------
3806
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003807- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3808 start byte and the continuation byte(s) are now considered invalid, instead
3809 of the number of bytes specified by the start byte.
3810 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3811 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3812 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3813 Previous versions returned a single u'\ufffd'.
3814
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003815- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003816 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3817 arises from the "Overriding __eq__ blocks inheritance ..." warning
3818 when turned into an exception: in this case the exception simply
3819 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003820
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003821- Issue #8748: Fix two issues with comparisons between complex and integer
3822 objects. (1) The comparison could incorrectly return True in some cases
3823 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3824 (2) The comparison raised an OverflowError for large integers, leading
3825 to unpredictable exceptions when combining integers and complex objects
3826 in sets or dicts.
3827
Mark Dickinson81336372010-05-30 12:12:25 +00003828- Issue #5211: Implicit coercion for the complex type is now completely
3829 removed. (Coercion for arithmetic operations was already removed in 2.7
3830 alpha 4, but coercion for rich comparisons was accidentally left in.)
3831
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003832- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3833 and error handler, instead of writing to the C stderr file in utf-8
3834
Georg Brandlfee0f442010-05-22 21:26:21 +00003835- Issue #7902: When using explicit relative import syntax, don't try implicit
3836 relative import semantics.

4196 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00004208- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4209 with a non-empty format string. This is an effort to future-proof user
4210 code. If a derived class does not currently implement __format__ but later
4211 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004212 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004213 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004273- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004274 argument `-` which tells it to read files to compile from stdin. Each line is
4275 read on demand and the named file is compiled immediately. (Original patch by
4276 Piotr Ożarowski).

4663 strings,
4664 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Antoine Pitroud840e512010-02-04 20:20:18 +00004698- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004699 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004700 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004705- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004706 file position when calling `truncate()`. It would previously change the file
4707 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004708 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4709

4711 class used to represent files stored inside an archive. The new
4712 implementation is significantly faster and can be wrapped in a
4713 ``io.BufferedReader`` object for more speedups. It also solves an issue
4714 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4715 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004725- Issue #7748: Since unicode values are supported for some metadata options in
4726 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4727 encoded string for them. This ensures that the upload and register commands
4728 send the correct values to PyPI without any error.

4804
Georg Brandlba83f822010-03-14 09:50:54 +00004805- The ``__complex__()`` method is now looked up on the class of instances to
4806 make it consistent with other special methods.

4810
Mark Dickinson1b34d252010-01-01 17:27:30 +00004811- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004812 DeprecationWarning when passed a float argument where an integer was expected.
4813 These functions and methods now raise TypeError instead. The majority of the
4814 effects of this change are in the extension modules, but some core functions
4815 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4816 and many unicode/str methods.

4830 of integers: the result of a/b is now correctly rounded for ints a and b (at
4831 least on IEEE 754 platforms), and in particular does not depend on the
4832 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004841 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004998- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4999 decimal string that's guaranteed to round back to x under correct rounding
5000 (with round-half-to-even rounding mode). Previously it gave a string based on
5001 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5002 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5003 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005005- Issue #7117: On almost all platforms: float-to-string and string-to-float
5006 conversions within Python are now correctly rounded. Places these conversions
5007 occur include: str for floats and complex numbers; the float and complex
5008 constructors; old-style and new-style numeric formatting; serialization and
5009 deserialization of floats and complex numbers using marshal, pickle and json;
5010 parsing of float and imaginary literals in Python code; Decimal-to-float
5011 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005012
Georg Brandlba83f822010-03-14 09:50:54 +00005013 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5014 providing correctly-rounded strtod and dtoa C functions. This code is
5015 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5016 the C compiler. There may be a small number of platforms on which correct
5017 operation of this code cannot be guaranteed, so the code is not used: notably,
5018 this applies to platforms where the C double format is not IEEE 754 binary64,
5019 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5020 and Python's configure script is unable to determine how to change the FPU
5021 precision. On these platforms conversions use the platform strtod and dtoa,
5022 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005024- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5025 uses the correctly-rounded string <-> float conversions described above (when
5026 available), and so produces correctly rounded results that will display nicely
5027 under the float repr. There are two related small changes: (1) round now
5028 accepts any class with an ``__index__()`` method for its second argument (but
5029 no longer accepts floats for the second argument), and (2) an excessively
5030 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5031 raises an exception.

6616 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6617 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6618 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00006673 leak-chasing test runs give sensible results. The previous method of reaping
6674 threads could return successfully while some Thread objects were still
6675 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006676
Georg Brandlba83f822010-03-14 09:50:54 +00006677- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

6693 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006694 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6695 the tests if DISPLAY is defined but can't be used.

6701 import both normal and optimised versions of modules. test_heapq and
6702 test_warnings have been adjusted to use it, tests for other modules with both
6703 C and Python implementations in the stdlib can be adjusted to use it over

Georg Brandlba83f822010-03-14 09:50:54 +00006712- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
6713 should cause a test to be skipped are now done using import_module from test
6714 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006817- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6819 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6820 ``printf`` function, whereas PyString_FromFormat has an independent
6821 implementation and uses "%zd" on all platforms for size_t values.

6830 method is allowed to return either an int or a long, but the behaviour of
6831 float objects should not change to respect backward compatibility.
6832
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006833- Issue #3751: str.rpartition would perform a left-partition when called with
6834 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006838- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006839 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006840 was correctly parsed but parsing of subsequent arguments failed.
6841
Vinay Sajip35e3b032008-09-01 14:33:59 +00006842- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006843 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6844 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6845 when given a tuple of classes as second argument, were looking up
6846 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6847 type object.
6848
Neal Norwitz18aa3882008-08-24 05:04:52 +00006849- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006918 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6919 for catch_warnings() also led to an improvement in the raising of a
6920 DeprecationWarning related to warnings.warn_explicit().

6948
Benjamin Peterson37346b22008-08-23 20:27:43 +00006949- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006986What's New in Python 2.6 beta 3?
6987================================
6988
Barry Warsaw07a4a382008-08-21 01:15:08 +00006989*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006990
6991Core and Builtins
6992-----------------
6993
Guido van Rossumf8402962008-08-20 15:01:50 +00006994- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6995 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6996 extensions do not automatically benefit from the class attribute
6997 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6998 to their tp_flags field if they care. This is a backwards
6999 compatibility feature; in 3.0, all types will use the cache by
7000 default.
7001
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007002- Keyword arguments can now follow starred arguments. (``f(a, *args,
7003 keyword=23)`` is now valid syntax.)
7004
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007005- ctypes function pointers that are COM methods have a boolean True
7006 value again.
7007
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007008- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7009 by denying s# to parse objects that have a releasebuffer procedure,
7010 and introducing s*.
7011
Georg Brandl1e13ea92008-08-11 09:07:59 +00007012- Issue #3537: Fix an assertion failure when an empty but presized dict
7013 object was stored in the freelist.
7014
Mark Dickinsonb6467572008-08-04 21:30:09 +00007015- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7016 ValueError consistently across platforms.
7017
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007018- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7019 (64bit Unix, for example), unichr() would truncate its argument and return
7020 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7021
Neal Norwitze7d8be82008-07-31 17:17:14 +00007022- Apply security patches from Apple.
7023
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007024- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7025 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7026
Antoine Pitrou92f82162008-07-25 22:22:08 +00007027- Issue #1819: function calls with several named parameters are now on
7028 average 35% faster (as measured by pybench).
7029
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007030- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7031 the python debugger steps into a class statement: the free variables (local
7032 variables defined in an outer scope) would be deleted from the outer scope.
7033
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007034- Issue #2620: Overflow checking when allocating or reallocating memory
7035 was not always being done properly in some python types and extension
7036 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7037 all been updated to perform better checks and places in the code that
7038 would previously leak memory on the error path when such an allocation
7039 failed have been fixed.

7042-------
7043
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007044- Issue #3612: Added some missing basic types in ctypes.wintypes.
7045
Benjamin Petersone977ad42008-08-20 01:42:01 +00007046- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7047 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7048
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007049- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7050 version reported by these tools does not necessarily follow the python
7051 version numbering scheme, so the module is less strict when parsing it.
7052
Nick Coghlanf70385a2008-08-18 12:42:46 +00007053- Issue #2235: Added Py3k warnings for types which will become unhashable
7054 under the stricter __hash__ inheritance rules in 3.0. Several types
7055 which did not meet the rules for hash invariants and were already
7056 unhashable in 3.0 have now been explicitly flagged as unhashable in
7057 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7058 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7059
Brett Cannon88f801d2008-08-18 00:46:22 +00007060- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7061 imported into the module but exposed as part of the module's API.
7062
Brett Cannon7b96f072008-08-18 00:41:11 +00007063- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7064
Brett Cannon46225e72008-08-18 00:36:52 +00007065- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007067- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7068
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007069- Issue #3575: Incremental decoder's decode function now takes bytearray
7070 by using 's*' instead of 't#'.
7071
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007072- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007073 fails unicode conversion on 2nd parameter. (windows only)
7074
Georg Brandl222e2082010-08-01 22:27:39 +00007075- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007076 in a redirect.
7077
Brett Cannonabe423e2008-08-16 21:47:07 +00007078- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007079 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007080
Facundo Batistaeb90b782008-08-16 14:44:07 +00007081- Issue #2776: fixed small issue when handling an URL with double slash
7082 after a 302 response in the case of not going through a proxy.
7083
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007084- Issue #2676: in the email package, content-type parsing was hanging on
7085 pathological input because of quadratic or exponential behaviour of a
7086 regular expression.
7087
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007088- Issue #3476: binary buffered reading through the new "io" library is now
7089 thread-safe.
7090
Brett Cannonbf3157b2008-08-14 05:00:03 +00007091- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7092 since mimetools itself is deprecated. Because modules are cached, all
7093 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7094
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007095- Issue #3134: shutil referenced undefined WindowsError symbol.
7096
Robert Schuppenies14646332008-08-10 11:01:53 +00007097- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7098 menu entries were not deleted.
7099
Brett Cannon83e81842008-08-09 23:30:55 +00007100- Copied the implementation of reduce() to _functools.reduce() to have a
7101 version that did not raise a DeprecationWarning under -3.
7102
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007103- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7104 a MemoryError rather than silently stop the iteration.
7105
Guido van Rossum59ce9012008-08-09 14:55:34 +00007106- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7107 to _sre.compile() will now be rejected. This should not affect anybody
7108 since the re.compile() function never generates invalid re-bytecode.
7109
Skip Montanaroa032bf42008-08-08 22:52:51 +00007110- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7111 upon first access it can be automatically initialized from the csv file if
7112 it wasn't initialized during instantiation.

Antoine Pitroude781a42008-08-09 12:43:23 +00007129 asking for a specific length. This problem only affected files opened

7186-----------------
7187
Georg Brandl3e483f62008-07-16 22:57:41 +00007188- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7189 its methods now allow for items objects that can be converted to
7190 an integer using operator.index().
7191
Mark Dickinson64b7e502008-07-16 09:40:03 +00007192- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7193 produced a ValueError instead of giving the correct float.
7194
Eric Smitha5fa5a22008-07-16 00:11:49 +00007195- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7196 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7197
Mark Dickinson7103aa42008-07-15 19:08:33 +00007198- Issue #3008: the float type has a new instance method 'float.hex'
7199 and a new class method 'float.fromhex' to convert floating-point
7200 numbers to and from hexadecimal strings, respectively.
7201
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007202- Issue #2235: __hash__ is once again inherited by default. To allow
7203 collections.Hashable to remain meaningful in the presence of the
7204 default hash implementation (object.__hash__), it is now possible
7205 to explicit block inheritance of hash by setting __hash__=None at
7206 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7207 level.
7208
Nick Coghlanb028f502008-07-13 14:52:36 +00007209- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7210 the parent module cannot be found while performing an absolute import.
7211 This means that an incorrectly defined __package__ attribute will
7212 now only prevent relative imports in that module rather than causing
7213 all imports from that module to fail.
7214
Nick Coghlan14ff9942008-07-08 14:21:42 +00007215- Issue #2517: Allow unicode messages in Exceptions again by correctly

7225 another thread's dictionary.
7226
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007227- Issue #3004: Minor change to slice.indices(): the start and stop
7228 arguments are now treated identically, making the behaviour easier
7229 to describe and understand. For example, slice(None, -10,
7230 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7231 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7232 10, -1).
7233
Georg Brandl278fc502008-07-19 12:46:12 +00007234- Issue #3219: Calling a function with repeated keyword arguments,
7235 f(a=2, a=23), would not cause a syntax error. This was a regression
7236 from 2.4 caused by the switch to the new compiler.

7247 error when they failed.
7248
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007249- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007274- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7275 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007276 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007277 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007293- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7679
Brett Cannonb61d8012008-05-11 23:39:04 +00007680- ``Lib/lib-old`` is now added to sys.path.
7681
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007682- On MacOS X it is now possible to install the framework in 64-bit
7683 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007684 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007685
7686 This is controlled by the configure argument ``--with-universal-archs``:
7687
7688 - ``--with-universal-archs=all``: install 4-way universal
7689
7690 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7691
7692 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7693
7694 This option should be used in combination with ``--enable-universalsdk=``.
7695
7696 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7703- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007704
7705- The PyString functions have been renamed to PyBytes. A batch of
7706 defines were added so that the linker still sees the original
7707 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007745- Issue #1631171: Re-implement the 'warnings' module in C (the
7746 original Python code has been kept as backup). This will allow for
7747 using the 'warning's machinery in such places as the parser where
7748 use of pure Python code is not possible. Both the ``showarning()``
7749 and ``formatwarning()`` gain an optional 'line' argument which is
7750 not called by default for backwards-compatibility reasons. Setting
7751 ``warnings.showwarning()`` to an implementation that lacks support
7752 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007777- The getpass module has been improved on Unix. It now uses /dev/tty
7778 by default and uses stderr instead of stdout. A GetPassWarning is
7779 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007795 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007815- Issue #2550: The approach used by client/server code for obtaining
7816 ports to listen on in network-oriented tests has been refined in an
7817 effort to facilitate running multiple instances of the entire
7818 regression test suite in parallel without issue.
7819 test_support.bind_port() has been fixed such that it will always
7820 return a unique port -- which wasn't always the case with the
7821 previous implementation, especially if socket options had been set
7822 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7823 new implementation of bind_port() will actually raise an exception
7824 if it is passed an AF_INET/SOCK_STREAM socket with either the
7825 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7826 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7827 the socket it's been passed. This currently only applies to
7828 Windows. This option prevents any other sockets from binding to the
7829 host/port we've bound to, thus removing the possibility of the
7830 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7831 when a second SOCK_STREAM socket binds and accepts to a host/port
7832 that's already been bound by another socket. The optional preferred
7833 port parameter to bind_port() has been removed. Under no
7834 circumstances should tests be hard coding ports!
7835
7836 test_support.find_unused_port() has also been introduced, which will
7837 pass a temporary socket object to bind_port() in order to obtain an
7838 unused port. The temporary socket object is then closed and
7839 deleted, and the port is returned. This method should only be used
7840 for obtaining an unused port in order to pass to an external program
7841 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7842 a parameter to a server-oriented class that doesn't give you direct
7843 access to the underlying socket used.
7844
7845 Finally, test_support.HOST has been introduced, which should be used
7846 for the host argument of any relevant socket calls (i.e. bind and
7847 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007848
7849 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007850 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007851 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7852 test_asynchat and test_socket_ssl.
7853
Georg Brandl3ee81df2008-05-17 18:14:43 +00007854 It is now possible for multiple instances of the regression test
7855 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008134- Added the future_builtins module, which contains hex() and oct().
8135 These are the PEP 3127 version of these functions, designed to be
8136 compatible with the hex() and oct() builtins from Python 3.0. They
8137 differ slightly in their output formats from the existing, unchanged
8138 Python 2.6 builtins. The expected usage of the future_builtins
8139 module is:
8140 from future_builtins import hex, oct
8141
Eric Smith7ef40bf2008-02-20 23:34:22 +00008142- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8143 exponents for exponents with absolute value < 100. Follows C99
8144 standard. This is a change on Windows, which would use 3 digits.
8145 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8146 so that any alterations it does to the resulting string will be
8147 available in stringlib/formatter.h (for float.__format__).
8148
Eric Smith5a3c1352008-02-19 13:21:56 +00008149- Implemented PEP 3101, Advanced String Formatting. This adds a new
8150 builtin format(); a format() method for str and unicode; a
8151 __format__() method to object, str, unicode, int, long, float, and
8152 datetime; the class string.Formatter; and the C API
8153 PyObject_Format().
8154
Georg Brandl3ee81df2008-05-17 18:14:43 +00008155- Fixed several potential crashes, all caused by specially crafted
8156 __del__ methods exploiting objects in temporarily inconsistent
8157 state.

8168 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008169
Georg Brandl3ee81df2008-05-17 18:14:43 +00008170- Issue #2045: Fix an infinite recursion triggered when printing a
8171 subclass of collections.defaultdict, if its default_factory is set
8172 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008173
Christian Heimesf75dbef2008-02-08 00:11:31 +00008174- Fixed a minor memory leak in dictobject.c. The content of the free
8175 list was not freed on interpreter shutdown.
8176
Georg Brandl21e99f42010-03-07 15:23:59 +00008177- Limit free list of method and built-in function objects to 256

8181 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008182 to compact the internal free lists of pre-allocted ints and floats.
8183
Georg Brandl3ee81df2008-05-17 18:14:43 +00008184- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8185 calls. Python expected the return type int but the fork familie
8186 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008194- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8195 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008196
Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8198 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008199
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200- Patch #1473257: generator objects gain a gi_code attribute. This is
8201 the same object as the func_code attribute of the function that
8202 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Issue #1920: "while 0" statements were completely removed by the
8205 compiler, even in the presence of an "else" clause, which is
8206 supposed to be run when the condition is false. Now the compiler
8207 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008208
Guido van Rossumeead05f2008-01-24 18:21:02 +00008209- A few crashers fixed: weakref_in_del.py (issue #1377858);
8210 loosing_dict_ref.py (issue #1303614, test67.py);
8211 borrowed_ref_[34].py (not in tracker).
8212
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008213- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008214 suppressed while an extension is loaded by calling SetErrorMode in
8215 dynload_win.c. The error is still reported properly.
8216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008218 several extension methods and modules do not work without unicode
8219 support.
8220
Georg Brandl26543b12008-01-21 18:36:51 +00008221- Issue #1882: when compiling code from a string, encoding cookies in the
8222 second line of code were not always recognized correctly.
8223
Georg Brandl14404b62008-01-19 19:27:05 +00008224- Issue #1679: "0x" was taken as a valid integer literal.
8225
Georg Brandl6caad7d2008-01-26 14:19:22 +00008226- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008227 added.
8228
Christian Heimesc94e2b52008-01-14 04:13:37 +00008229- sys.float_info / PyFloat_GetInfo: The floating point information
8230 object was converted from a dict to a specialized structseq object.
8231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Patch #1816: Added sys.flags structseq. It exposes the status of
8233 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008234
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235- Objects/structseq.c: Implemented new structseq representation. The
8236 patch makes structseqs (e.g. the return value of os.stat) more
8237 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Patch #1700288: added a type attribute cache that caches method
8240 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008241
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008242- Bug #1776: __import__() no longer accepts filenames on any platform.
8243 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008244
Georg Brandlaed6c662008-01-07 17:25:53 +00008245- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8246
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8248 envvar and sys.dont_write_bytecode attribute. All these can be set
8249 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008250
Georg Brandl3ee81df2008-05-17 18:14:43 +00008251- Improve some exception messages when Windows fails to load an
8252 extension module. Now we get for example '%1 is not a valid Win32
8253 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008254
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8258 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008259
Christian Heimes0a8143f2007-12-18 23:22:54 +00008260- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261 and INF. float("nan"), float("inf") and float("-inf") now work on
8262 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Compiler now generates simpler and faster code for dictionary
8265 literals. The oparg for BUILD_MAP now indicates an estimated
8266 dictionary size. There is a new opcode, STORE_MAP, for adding
8267 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008268
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Issue #1620: New property decorator syntax was modifying the
8272 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #1538: Avoid copying string in split/rsplit if the split char
8275 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008276
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008277- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008278 SystemError.
8279
Nick Coghlanef01d822007-12-03 12:55:17 +00008280- PEP 366: Allow explicit relative imports when executing modules
8281 inside packages with the -m switch via a new module level
8282 __package__ attribute.
8283

8285 running, and if the deallocation of its frames somehow calls the
8286 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008287

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008291 attribute of an empty cell object.
8292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #1460: The utf-7 incremental decoder did not accept truncated
8294 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Patch #1739468: Directories and zipfiles containing a __main__.py
8297 file can now be directly executed by passing their name to the
8298 interpreter. The directory/zipfile is automatically inserted as the
8299 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008300
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301- Issue #1265: Fix a problem with sys.settrace, if the tracing
8302 function uses a generator expression when at the same time the
8303 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008304
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008305- sets and frozensets now have an isdisjoint() method.
8306
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008307- optimize the performance of builtin.sum().
8308
Neal Norwitz44f326e2007-10-05 05:29:17 +00008309- Fix warnings found by the new version of the Coverity checker.
8310
Georg Brandl21e99f42010-03-07 15:23:59 +00008311- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008312 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8313 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008314
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Issue #1686386: Tuple's tp_repr did not take into account the
8316 possibility of having a self-referential tuple, which is possible
8317 from C code. Nor did object's tp_str consider that a type's tp_str
8318 could do something that could lead to an inifinite recursion.
8319 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8320 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008321
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Issue #1164: It was possible to trigger deadlock when using the
8323 'print' statement to write to a file since the GIL was not released
8324 as needed. Now PyObject_Print() does the right thing along with
8325 various tp_print implementations of the built-in types and those in
8326 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008327
Georg Brandl3ee81df2008-05-17 18:14:43 +00008328- Issue #1147: Exceptions were directly allowing string exceptions in
8329 their throw() method even though string exceptions no longer
8330 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008331
Georg Brandl3ee81df2008-05-17 18:14:43 +00008332- Issue #1096: Prevent a segfault from getting the repr of a very
8333 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008334
Brett Cannon1e534b52007-09-07 04:18:30 +00008335- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336 PyObject_Call() never calling back out to Python code to trigger
8337 recursion depth updates/checks. Required the creation of a static
8338 RuntimeError instance in case normalizing an exception put the
8339 recursion check value past its limit. Fixes crashers
8340 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008341
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342- Patch #1031213: Decode source line in SyntaxErrors back to its

8346 with %G.
8347
Georg Brandl3ee81df2008-05-17 18:14:43 +00008348- Prevent expandtabs() on string and unicode objects from causing a
8349 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008350

Neal Norwitz0ac60192007-05-27 04:08:54 +00008355- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356 __*__ attributes. (Some already existed, e.g., __doc__ and
8357 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008358
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008359- Add -3 option to the interpreter to warn about features that are
8360 deprecated and will be changed/removed in Python 3.0.
8361
Georg Brandl2134e752007-05-21 20:34:16 +00008362- Patch #1686487: you can now pass any mapping after '**' in function
8363 calls.
8364
Collin Winter62903052007-05-18 23:11:24 +00008365- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366 "except E as target:". This is to provide forwards compatibility
8367 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008368
Brett Cannon229cee22007-05-05 01:34:02 +00008369- Deprecate BaseException.message as per PEP 352.
8370
Georg Brandl3ee81df2008-05-17 18:14:43 +00008371- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008372 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008373
Vinay Sajip8549ce32007-05-06 17:53:37 +00008374- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008375 setting a plain string, ie don't expand to single letter identifiers.
8376
Raymond Hettinger13936692007-04-11 18:40:58 +00008377- Request #1191699: Slices can now be pickled.
8378
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008379- Request #1193128: str.translate() now allows a None argument for
8380 translations that only remove characters without re-mapping the
8381 remaining characters.
8382
Georg Brandl5cb76c12007-03-21 09:00:39 +00008383- Patch #1682205: a TypeError while unpacking an iterable is no longer
8384 masked by a generic one with the message "unpack non-sequence".
8385
Neal Norwitzaa754b72007-03-21 06:39:48 +00008386- Remove unused file Python/fmod.c.
8387
Guido van Rossum143b5642007-03-23 04:58:42 +00008388- Bug #1683368: The object.__init__() and object.__new__() methods are
8389 now stricter in rejecting excess arguments. The only time when
8390 either allows excess arguments is when it is not overridden and the
8391 other one is. For backwards compatibility, when both are
8392 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008393 warning later). Also, type.__init__() insists on the same signature
8394 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008395
Georg Brandl3ee81df2008-05-17 18:14:43 +00008396- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8397 object to complex using its __complex__() method before falling back
8398 to the __float__() method. Therefore, the functions in the cmath
8399 module now can operate on objects that define a __complex__()
8400 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008401
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402- Patch #1623563: allow __class__ assignment for classes with
8403 __slots__. The old and the new class are still required to have the
8404 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008405
Georg Brandl3ee81df2008-05-17 18:14:43 +00008406- Patch #1642547: Fix an error/crash when encountering syntax errors

8410 ``object.__reduce_ex__()`` is called with an object that is faking
8411 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008412
Georg Brandl3ee81df2008-05-17 18:14:43 +00008413- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008416- Patch #1444529: the builtin compile() now accepts keyword arguments.
8417
Georg Brandl7b9c5552007-03-12 14:30:05 +00008418- Bug #1678647: write a newline after printing an exception in any
8419 case, even when converting the value to a string failed.
8420
Georg Brandl871f1bc2007-03-12 13:17:36 +00008421- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008422 its argument, if it exists. If not, it will work like before. This
8423 allows customizing the output of dir() in the presence of a
8424 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008425
Collin Winter276887b2007-03-12 16:11:39 +00008426- Patch #922167: Python no longer segfaults when faced with infinitely
8427 self-recursive reload() calls (as reported by bug #742342).
8428
Georg Brandl3ee81df2008-05-17 18:14:43 +00008429- Patch #1675981: remove unreachable code from ``type.__new__()``
8430 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00008431
Georg Brandl3ee81df2008-05-17 18:14:43 +00008432- Patch #1491866: change the complex() constructor to allow

8944 ".cpp" too.
8945
Facundo Batistad918a652007-04-24 13:54:38 +00008946- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008947 the client's request was successfully received, understood, and
8948 accepted. Now in these cases no error is raised in urllib (issue
8949 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008950

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008957- Added a timeout parameter to the constructor of other protocols
8958 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8959 work started with create_connection() and timeout in httplib, and
8960 closes patch #723312.
8961
Vinay Sajip8549ce32007-05-06 17:53:37 +00008962- Patch #1676823: Added create_connection() to socket.py, which may be
8963 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008964 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008965
Martin v. Löwis0af33882007-03-23 13:27:15 +00008966- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008973- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8974 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00008975 directories.
8976

8978 GNOME or KDE browser, depending on whether there is a session of one

8986
Georg Brandlf66b6032007-03-14 08:27:52 +00008987- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988 AttributeError instead of an IOError when the server's response
8989 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008990
Georg Brandl3ee81df2008-05-17 18:14:43 +00008991- Patch #957650: "%var%" environment variable references are now
8992 properly expanded in ntpath.expandvars(), also "~user" home
8993 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008994
Georg Brandl3ee81df2008-05-17 18:14:43 +00008995- Patch #1429539: pdb now correctly initializes the __main__ module
8996 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008997 correctly now.
8998
Georg Brandlbad6f192007-03-13 21:32:56 +00008999- The nonobvious commands.getstatus() function is now deprecated.

9005
Georg Brandl3ee81df2008-05-17 18:14:43 +00009006- Patch #1530482: add pydoc.render_doc() which returns the
9007 documentation for a thing instead of paging it to stdout, which
9008 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009009
Georg Brandl3ee81df2008-05-17 18:14:43 +00009010- Patch #1533909: the timeit module now accepts callables in addition

9016 parameter which can be set to False to prevent the default
9017 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00009019- Patch #1581073: add a flag to textwrap that prevents the dropping of

9021
Georg Brandl92a6bae2007-03-13 17:43:32 +00009022- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009023 are set for invalid interpolation sequences that would lead to
9024 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009025

9038
Georg Brandl94fe3f52007-03-13 09:32:11 +00009039- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00009040 field names in its exception message if you try to write a record
9041 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00009059

9067 returned string up to the first NUL character.
9068

9078
Georg Brandl3ee81df2008-05-17 18:14:43 +00009079- unittest now verifies more of its assumptions. In particular,
9080 TestCase and TestSuite subclasses (not instances) are no longer
9081 accepted in TestSuite.addTest(). This should cause no
9082 incompatibility since it never made sense with ordinary subclasses
9083 -- the failure just occurred later, with a more cumbersome
9084 exception.

9093 given a unicode argument and os.listdir() returns unicode filenames.
9094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Patch #1673619: setup.py identifies extension modules it doesn't

9449 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9450 silently miscode subclasses of those types. Now, it raises a
9451 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009452

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009466- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009467 time so that opening a database previously created with the DB_DUP
9468 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9469 opens. Specifically: dictionary assignment to a DB object will
9470 replace all values for a given key when the database allows
9471 duplicate values. DB users should use DB.put(k, v) when they want
9472 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009473

9479 characters with ASCII value less than 32. Also, it correctly quotes
9480 dots only if they occur on a single line, as opposed to the previous
9481 behavior of quoting dots if they are the second character of any
9482 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009483
