1149
1150- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1151 and later systems as is currently done for Python 3.x installers.
1152 For 2.7.7 only, we will provide three installers:
1153 the legacy deprecated 10.3+ 32-bit-only format;
1154 the newer 10.5+ 32-bit-only format;
1155 and the unchanged 10.6+ 64-/32-bit format.
1156 Although binary installers will no longer be available from
1157 python.org as of 2.7.8, it will still be possible to build from
1158 source on 10.3.9 and 10.4 systems if necessary.
1159 See Mac/BuildScript/README.txt for more information.

2541 32-bit-only installer Pythons on systems with Xcode 4 (currently
2542 OS X 10.8, 10.7, and optionally 10.6).
2543 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2544 * Since Xcode 4 removes ppc support, extension module builds now
2545 check for ppc compiler support and by default remove ppc and
2546 ppc64 archs when they are not available.
2547 * Extension module builds now revert to using system installed
2548 headers and libs (/usr and /System/Library) if the SDK used
2549 to build the interpreter is not installed or has moved.
2550 * Try to avoid building extension modules with deprecated
2551 and problematic Apple llvm-gcc compiler. If original compiler
2552 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002989- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002990 has left two versions of customize_compiler, the original in
2991 distutils.sysconfig and another copy in distutils.ccompiler, with some
2992 parts of distutils calling one and others using the other.
2993 Complete the revert back to only having one in distutils.sysconfig as
2994 is the case in 3.x.
2995
Ned Deily0d0ea482012-02-10 12:59:06 +01002996- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2997 Distutils-based packages with C extension modules may fail because
2998 Apple has removed gcc-4.2, the version used to build python.org
2999 64-bit/32-bit Pythons. If the user does not explicitly override
3000 the default C compiler by setting the CC environment variable,
3001 Distutils will now attempt to compile extension modules with clang
3002 if gcc-4.2 is required but not found. Also as a convenience, if
3003 the user does explicitly set CC, substitute its value as the default
3004 compiler in the Distutils LDSHARED configuration variable for OS X.
3005 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3006 SDK, neither of which are available in Xcode 4. This change does not
3007 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003257- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3258 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3259 interpreter process. This could cause failures in non-Distutils subprocesses
3260 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003261 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003262 deployment target only in the environment of each build subprocess. It is
3263 still possible to globally override the default by setting
3264 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be

4297 This prevents user-created self-referencing ordered dictionaries from
4298 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004759- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4760 start byte and the continuation byte(s) are now considered invalid, instead
4761 of the number of bytes specified by the start byte.
4762 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4763 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4764 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4765 Previous versions returned a single u'\ufffd'.
4766
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004767- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004768 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4769 arises from the "Overriding __eq__ blocks inheritance ..." warning
4770 when turned into an exception: in this case the exception simply
4771 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004772
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004773- Issue #8748: Fix two issues with comparisons between complex and integer
4774 objects. (1) The comparison could incorrectly return True in some cases
4775 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4776 (2) The comparison raised an OverflowError for large integers, leading
4777 to unpredictable exceptions when combining integers and complex objects
4778 in sets or dicts.
4779
Mark Dickinson81336372010-05-30 12:12:25 +00004780- Issue #5211: Implicit coercion for the complex type is now completely
4781 removed. (Coercion for arithmetic operations was already removed in 2.7
4782 alpha 4, but coercion for rich comparisons was accidentally left in.)
4783
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004784- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4785 and error handler, instead of writing to the C stderr file in utf-8
4786
Georg Brandlfee0f442010-05-22 21:26:21 +00004787- Issue #7902: When using explicit relative import syntax, don't try implicit

5148 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00005160- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5161 with a non-empty format string. This is an effort to future-proof user
5162 code. If a derived class does not currently implement __format__ but later
5163 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005164 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005165 Python 3.3 and it will be an error in Python 3.4.

5216 InvalidOperation instead of returning False. (Comparisons involving a quiet
5217 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlba83f822010-03-14 09:50:54 +00005559- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00005560 is run with the -OO flag. Tests requiring docstrings are skipped.
5561
Georg Brandlba83f822010-03-14 09:50:54 +00005562- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
5563 now also used by regrtest to run all the tests in a temporary directory. The
5564 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
5565 Xicluna who helped with the patch.

5582 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005583 library would return a bogus result; on Solaris, it was possible to crash the
5584 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00005597- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5598 and add the additional members returned in an OSVERSIONINFOEX structure. The
5599 new members are service_pack_major, service_pack_minor, suite_mask, and
5600 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00005601
Georg Brandlba83f822010-03-14 09:50:54 +00005602- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5603 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5604 returning NULL. The macro now returns a statically allocated empty string
5605 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00005606
Antoine Pitrou64672132010-01-13 07:55:48 +00005607- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00005614 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
5615 strings,
5616 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5617 numeric strings corresponding to subnormal values,
5618 (3) a memory leak for some values large enough to cause overflow, and
5619 (4) a number of flaws that could lead to incorrectly rounded results.

R. David Murray63e4fd72010-02-10 22:42:04 +00005636- Issue #7835: shelve should no longer produce mysterious warnings during
5637 interpreter shutdown.
5638
Georg Brandlba83f822010-03-14 09:50:54 +00005639- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
5640 XML processing instructions and comments. These raw characters are allowed
5641 by the XML specification, and are necessary when outputting e.g. PHP code in
5642 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00005650- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005651 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005652 Also, raise ValueError rather than TypeError when an unknown TIPC address
5653 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005657- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005658 file position when calling `truncate()`. It would previously change the file
5659 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005660 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5661
Georg Brandlba83f822010-03-14 09:50:54 +00005662- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5663 class used to represent files stored inside an archive. The new
5664 implementation is significantly faster and can be wrapped in a
5665 ``io.BufferedReader`` object for more speedups. It also solves an issue
5666 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5667 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00005676
Georg Brandlba83f822010-03-14 09:50:54 +00005677- Issue #7748: Since unicode values are supported for some metadata options in
5678 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5679 encoded string for them. This ensures that the upload and register commands
5680 send the correct values to PyPI without any error.

5755-----------------
5756
Georg Brandlba83f822010-03-14 09:50:54 +00005757- The ``__complex__()`` method is now looked up on the class of instances to
5758 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005759
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005760- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5762
Mark Dickinson1b34d252010-01-01 17:27:30 +00005763- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005764 DeprecationWarning when passed a float argument where an integer was expected.
5765 These functions and methods now raise TypeError instead. The majority of the
5766 effects of this change are in the extension modules, but some core functions
5767 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5768 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00005781- Issue #1811: Improve accuracy and cross-platform consistency for true division
5782 of integers: the result of a/b is now correctly rounded for ints a and b (at
5783 least on IEEE 754 platforms), and in particular does not depend on the
5784 internal representation of a long.

5792
Georg Brandlba83f822010-03-14 09:50:54 +00005793 These executables now work properly with the arch(1) command: ``arch -ppc
5794 python`` will start a universal binary version of python in PPC mode (unlike

5934 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005935
Georg Brandlba83f822010-03-14 09:50:54 +00005936- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5937 1e50 in absolute value.

5940 1e-100 used to raise OverflowError, but now gives the requested 120
5941 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00005950- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5951 decimal string that's guaranteed to round back to x under correct rounding
5952 (with round-half-to-even rounding mode). Previously it gave a string based on
5953 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5954 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5955 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005957- Issue #7117: On almost all platforms: float-to-string and string-to-float
5958 conversions within Python are now correctly rounded. Places these conversions
5959 occur include: str for floats and complex numbers; the float and complex
5960 constructors; old-style and new-style numeric formatting; serialization and
5961 deserialization of floats and complex numbers using marshal, pickle and json;
5962 parsing of float and imaginary literals in Python code; Decimal-to-float
5963 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005964
Georg Brandlba83f822010-03-14 09:50:54 +00005965 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5966 providing correctly-rounded strtod and dtoa C functions. This code is
5967 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5968 the C compiler. There may be a small number of platforms on which correct
5969 operation of this code cannot be guaranteed, so the code is not used: notably,
5970 this applies to platforms where the C double format is not IEEE 754 binary64,
5971 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5972 and Python's configure script is unable to determine how to change the FPU
5973 precision. On these platforms conversions use the platform strtod and dtoa,
5974 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005976- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5977 uses the correctly-rounded string <-> float conversions described above (when
5978 available), and so produces correctly rounded results that will display nicely
5979 under the float repr. There are two related small changes: (1) round now
5980 accepts any class with an ``__index__()`` method for its second argument (but
5981 no longer accepts floats for the second argument), and (2) an excessively
5982 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5983 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007790- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7791 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7792 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7793 ``printf`` function, whereas PyString_FromFormat has an independent
7794 implementation and uses "%zd" on all platforms for size_t values.
7795 This makes a difference on win64, where ``printf`` needs "%Id" to display
7796 64bit values.
7797
Benjamin Peterson97179b02008-09-09 20:55:01 +00007798- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7799 error.
7800
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007801- Issue #3777: long() applied to a float object now always return a long
7802 object; previously an int would be returned for small values. the __long__
7803 method is allowed to return either an int or a long, but the behaviour of
7804 float objects should not change to respect backward compatibility.
7805
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007806- Issue #3751: str.rpartition would perform a left-partition when called with
7807 a unicode argument.
7808
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007809- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007811- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007812 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007813 was correctly parsed but parsing of subsequent arguments failed.
7814
Vinay Sajip35e3b032008-09-01 14:33:59 +00007815- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007816 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7817 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7818 when given a tuple of classes as second argument, were looking up
7819 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7820 type object.
7821
Neal Norwitz18aa3882008-08-24 05:04:52 +00007822- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00007830- Silenced another compiler warning about a used but not defined
7831 function 'stringlib_contains_obj'.
7832
Benjamin Peterson712ee922008-08-24 18:10:20 +00007833- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
7834 ``__delslice__``.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007891 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7892 for catch_warnings() also led to an improvement in the raising of a
7893 DeprecationWarning related to warnings.warn_explicit().
7894

7921
Benjamin Peterson37346b22008-08-23 20:27:43 +00007922- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007959What's New in Python 2.6 beta 3?
7960================================
7961
Barry Warsaw07a4a382008-08-21 01:15:08 +00007962*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007963
7964Core and Builtins
7965-----------------
7966
Guido van Rossumf8402962008-08-20 15:01:50 +00007967- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7968 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7969 extensions do not automatically benefit from the class attribute
7970 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7971 to their tp_flags field if they care. This is a backwards
7972 compatibility feature; in 3.0, all types will use the cache by
7973 default.
7974
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007975- Keyword arguments can now follow starred arguments. (``f(a, *args,
7976 keyword=23)`` is now valid syntax.)
7977
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007978- ctypes function pointers that are COM methods have a boolean True
7979 value again.
7980
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007981- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7982 by denying s# to parse objects that have a releasebuffer procedure,
7983 and introducing s*.
7984
Georg Brandl1e13ea92008-08-11 09:07:59 +00007985- Issue #3537: Fix an assertion failure when an empty but presized dict
7986 object was stored in the freelist.
7987
Mark Dickinsonb6467572008-08-04 21:30:09 +00007988- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7989 ValueError consistently across platforms.
7990
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007991- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7992 (64bit Unix, for example), unichr() would truncate its argument and return
7993 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7994
Neal Norwitze7d8be82008-07-31 17:17:14 +00007995- Apply security patches from Apple.
7996
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007997- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7998 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7999
Antoine Pitrou92f82162008-07-25 22:22:08 +00008000- Issue #1819: function calls with several named parameters are now on
8001 average 35% faster (as measured by pybench).
8002
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008003- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8004 the python debugger steps into a class statement: the free variables (local
8005 variables defined in an outer scope) would be deleted from the outer scope.
8006
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008007- Issue #2620: Overflow checking when allocating or reallocating memory
8008 was not always being done properly in some python types and extension
8009 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8010 all been updated to perform better checks and places in the code that
8011 would previously leak memory on the error path when such an allocation
8012 failed have been fixed.

8015-------
8016
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008017- Issue #3612: Added some missing basic types in ctypes.wintypes.
8018
Benjamin Petersone977ad42008-08-20 01:42:01 +00008019- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8020 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8021
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008022- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8023 version reported by these tools does not necessarily follow the python
8024 version numbering scheme, so the module is less strict when parsing it.
8025
Nick Coghlanf70385a2008-08-18 12:42:46 +00008026- Issue #2235: Added Py3k warnings for types which will become unhashable
8027 under the stricter __hash__ inheritance rules in 3.0. Several types
8028 which did not meet the rules for hash invariants and were already
8029 unhashable in 3.0 have now been explicitly flagged as unhashable in
8030 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8031 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8032
Brett Cannon88f801d2008-08-18 00:46:22 +00008033- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

8041
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008042- Issue #3575: Incremental decoder's decode function now takes bytearray
8043 by using 's*' instead of 't#'.
8044
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008045- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008046 fails unicode conversion on 2nd parameter. (windows only)
8047
Georg Brandl222e2082010-08-01 22:27:39 +00008048- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008049 in a redirect.
8050

Brett Cannon721b1452008-08-16 22:00:27 +00008052 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008053
Facundo Batistaeb90b782008-08-16 14:44:07 +00008054- Issue #2776: fixed small issue when handling an URL with double slash
8055 after a 302 response in the case of not going through a proxy.
8056
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008057- Issue #2676: in the email package, content-type parsing was hanging on
8058 pathological input because of quadratic or exponential behaviour of a
8059 regular expression.
8060
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008061- Issue #3476: binary buffered reading through the new "io" library is now
8062 thread-safe.
8063
Brett Cannonbf3157b2008-08-14 05:00:03 +00008064- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8065 since mimetools itself is deprecated. Because modules are cached, all
8066 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8067
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008068- Issue #3134: shutil referenced undefined WindowsError symbol.
8069
Robert Schuppenies14646332008-08-10 11:01:53 +00008070- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8071 menu entries were not deleted.
8072
Brett Cannon83e81842008-08-09 23:30:55 +00008073- Copied the implementation of reduce() to _functools.reduce() to have a

Antoine Pitroude781a42008-08-09 12:43:23 +00008102 asking for a specific length. This problem only affected files opened

8146
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008147- Issue #643841: The language reference now provides more detailed

8159-----------------
8160
Georg Brandl3e483f62008-07-16 22:57:41 +00008161- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8162 its methods now allow for items objects that can be converted to
8163 an integer using operator.index().
8164
Mark Dickinson64b7e502008-07-16 09:40:03 +00008165- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8166 produced a ValueError instead of giving the correct float.
8167
Eric Smitha5fa5a22008-07-16 00:11:49 +00008168- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8169 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8170
Mark Dickinson7103aa42008-07-15 19:08:33 +00008171- Issue #3008: the float type has a new instance method 'float.hex'
8172 and a new class method 'float.fromhex' to convert floating-point
8173 numbers to and from hexadecimal strings, respectively.
8174
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008175- Issue #2235: __hash__ is once again inherited by default. To allow
8176 collections.Hashable to remain meaningful in the presence of the
8177 default hash implementation (object.__hash__), it is now possible
8178 to explicit block inheritance of hash by setting __hash__=None at
8179 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8180 level.
8181
Nick Coghlanb028f502008-07-13 14:52:36 +00008182- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8183 the parent module cannot be found while performing an absolute import.
8184 This means that an incorrectly defined __package__ attribute will
8185 now only prevent relative imports in that module rather than causing
8186 all imports from that module to fail.
8187
Nick Coghlan14ff9942008-07-08 14:21:42 +00008188- Issue #2517: Allow unicode messages in Exceptions again by correctly

8198 another thread's dictionary.
8199
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008200- Issue #3004: Minor change to slice.indices(): the start and stop
8201 arguments are now treated identically, making the behaviour easier
8202 to describe and understand. For example, slice(None, -10,
8203 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8204 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8205 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008207- Issue #3219: Calling a function with repeated keyword arguments,
8208 f(a=2, a=23), would not cause a syntax error. This was a regression
8209 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008247- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8248 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008249 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008250 content-length. The problem had been corrected in the 2.4 branch, but never
8251 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008266- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8652
Brett Cannonb61d8012008-05-11 23:39:04 +00008653- ``Lib/lib-old`` is now added to sys.path.
8654
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008655- On MacOS X it is now possible to install the framework in 64-bit
8656 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008657 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008658
8659 This is controlled by the configure argument ``--with-universal-archs``:
8660
8661 - ``--with-universal-archs=all``: install 4-way universal
8662
8663 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8664
8665 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8666
8667 This option should be used in combination with ``--enable-universalsdk=``.
8668
8669 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00008677
8678- The PyString functions have been renamed to PyBytes. A batch of
8679 defines were added so that the linker still sees the original
8680 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008718- Issue #1631171: Re-implement the 'warnings' module in C (the
8719 original Python code has been kept as backup). This will allow for
8720 using the 'warning's machinery in such places as the parser where
8721 use of pure Python code is not possible. Both the ``showarning()``
8722 and ``formatwarning()`` gain an optional 'line' argument which is
8723 not called by default for backwards-compatibility reasons. Setting
8724 ``warnings.showwarning()`` to an implementation that lacks support
8725 for the ``line`` argument will raise a DeprecationWarning.

8749
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008750- The getpass module has been improved on Unix. It now uses /dev/tty
8751 by default and uses stderr instead of stdout. A GetPassWarning is
8752 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00008753

8765 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00008766
Georg Brandl3ee81df2008-05-17 18:14:43 +00008767- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008768 extension modules between 32 and 64 bit platforms. See the distutls

8772 threads at once without fear of crashing the Python interpreter. If
8773 file.close() is called while an object is in use by another thread
8774 an IOError exception will be raised and the file will not be closed.
8775
Thomas Hellerf7906482008-04-04 19:43:25 +00008776- The bundled libffi copy is now in sync with the recently released

8781 so the controlled environment will more closely mirror the typical
8782 script environment. This supports setup.py scripts that refer to
8783 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008788- Issue #2550: The approach used by client/server code for obtaining
8789 ports to listen on in network-oriented tests has been refined in an
8790 effort to facilitate running multiple instances of the entire
8791 regression test suite in parallel without issue.
8792 test_support.bind_port() has been fixed such that it will always
8793 return a unique port -- which wasn't always the case with the
8794 previous implementation, especially if socket options had been set
8795 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8796 new implementation of bind_port() will actually raise an exception
8797 if it is passed an AF_INET/SOCK_STREAM socket with either the
8798 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8799 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8800 the socket it's been passed. This currently only applies to
8801 Windows. This option prevents any other sockets from binding to the
8802 host/port we've bound to, thus removing the possibility of the
8803 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8804 when a second SOCK_STREAM socket binds and accepts to a host/port
8805 that's already been bound by another socket. The optional preferred
8806 port parameter to bind_port() has been removed. Under no
8807 circumstances should tests be hard coding ports!
8808
8809 test_support.find_unused_port() has also been introduced, which will
8810 pass a temporary socket object to bind_port() in order to obtain an
8811 unused port. The temporary socket object is then closed and
8812 deleted, and the port is returned. This method should only be used
8813 for obtaining an unused port in order to pass to an external program
8814 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8815 a parameter to a server-oriented class that doesn't give you direct
8816 access to the underlying socket used.
8817
8818 Finally, test_support.HOST has been introduced, which should be used
8819 for the host argument of any relevant socket calls (i.e. bind and
8820 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008821
8822 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008824 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8825 test_asynchat and test_socket_ssl.
8826
Georg Brandl3ee81df2008-05-17 18:14:43 +00008827 It is now possible for multiple instances of the regression test
8828 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009107- Added the future_builtins module, which contains hex() and oct().
9108 These are the PEP 3127 version of these functions, designed to be
9109 compatible with the hex() and oct() builtins from Python 3.0. They
9110 differ slightly in their output formats from the existing, unchanged
9111 Python 2.6 builtins. The expected usage of the future_builtins
9112 module is:
9113 from future_builtins import hex, oct
9114
Eric Smith7ef40bf2008-02-20 23:34:22 +00009115- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9116 exponents for exponents with absolute value < 100. Follows C99
9117 standard. This is a change on Windows, which would use 3 digits.
9118 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9119 so that any alterations it does to the resulting string will be
9120 available in stringlib/formatter.h (for float.__format__).
9121
Eric Smith5a3c1352008-02-19 13:21:56 +00009122- Implemented PEP 3101, Advanced String Formatting. This adds a new
9123 builtin format(); a format() method for str and unicode; a
9124 __format__() method to object, str, unicode, int, long, float, and
9125 datetime; the class string.Formatter; and the C API
9126 PyObject_Format().
9127
Georg Brandl3ee81df2008-05-17 18:14:43 +00009128- Fixed several potential crashes, all caused by specially crafted
9129 __del__ methods exploiting objects in temporarily inconsistent
9130 state.

9141 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009142
Georg Brandl3ee81df2008-05-17 18:14:43 +00009143- Issue #2045: Fix an infinite recursion triggered when printing a
9144 subclass of collections.defaultdict, if its default_factory is set
9145 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009146
Christian Heimesf75dbef2008-02-08 00:11:31 +00009147- Fixed a minor memory leak in dictobject.c. The content of the free
9148 list was not freed on interpreter shutdown.
9149
Georg Brandl21e99f42010-03-07 15:23:59 +00009150- Limit free list of method and built-in function objects to 256

9154 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009155 to compact the internal free lists of pre-allocted ints and floats.
9156
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9158 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00009170- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9171 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009172
Georg Brandl3ee81df2008-05-17 18:14:43 +00009173- Patch #1473257: generator objects gain a gi_code attribute. This is
9174 the same object as the func_code attribute of the function that
9175 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009176
Georg Brandl3ee81df2008-05-17 18:14:43 +00009177- Issue #1920: "while 0" statements were completely removed by the
9178 compiler, even in the presence of an "else" clause, which is
9179 supposed to be run when the condition is false. Now the compiler
9180 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009181
Guido van Rossumeead05f2008-01-24 18:21:02 +00009182- A few crashers fixed: weakref_in_del.py (issue #1377858);
9183 loosing_dict_ref.py (issue #1303614, test67.py);
9184 borrowed_ref_[34].py (not in tracker).
9185
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009186- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009187 suppressed while an extension is loaded by calling SetErrorMode in
9188 dynload_win.c. The error is still reported properly.
9189
Georg Brandl3ee81df2008-05-17 18:14:43 +00009190- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009191 several extension methods and modules do not work without unicode
9192 support.
9193
Georg Brandl26543b12008-01-21 18:36:51 +00009194- Issue #1882: when compiling code from a string, encoding cookies in the
9195 second line of code were not always recognized correctly.
9196
Georg Brandl14404b62008-01-19 19:27:05 +00009197- Issue #1679: "0x" was taken as a valid integer literal.
9198
Georg Brandl6caad7d2008-01-26 14:19:22 +00009199- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009200 added.
9201
Christian Heimesc94e2b52008-01-14 04:13:37 +00009202- sys.float_info / PyFloat_GetInfo: The floating point information
9203 object was converted from a dict to a specialized structseq object.
9204
Georg Brandl3ee81df2008-05-17 18:14:43 +00009205- Patch #1816: Added sys.flags structseq. It exposes the status of
9206 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009207
Georg Brandl3ee81df2008-05-17 18:14:43 +00009208- Objects/structseq.c: Implemented new structseq representation. The
9209 patch makes structseqs (e.g. the return value of os.stat) more
9210 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009211
Georg Brandl3ee81df2008-05-17 18:14:43 +00009212- Patch #1700288: added a type attribute cache that caches method
9213 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009214
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009215- Bug #1776: __import__() no longer accepts filenames on any platform.
9216 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009217
Georg Brandlaed6c662008-01-07 17:25:53 +00009218- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9219
Georg Brandl3ee81df2008-05-17 18:14:43 +00009220- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9221 envvar and sys.dont_write_bytecode attribute. All these can be set
9222 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009223
Georg Brandl3ee81df2008-05-17 18:14:43 +00009224- Improve some exception messages when Windows fails to load an
9225 extension module. Now we get for example '%1 is not a valid Win32
9226 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009233- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009234 and INF. float("nan"), float("inf") and float("-inf") now work on
9235 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- Compiler now generates simpler and faster code for dictionary
9238 literals. The oparg for BUILD_MAP now indicates an estimated
9239 dictionary size. There is a new opcode, STORE_MAP, for adding
9240 entries to the dictionary.

9252
Nick Coghlanef01d822007-12-03 12:55:17 +00009253- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00009269- Patch #1739468: Directories and zipfiles containing a __main__.py
9270 file can now be directly executed by passing their name to the
9271 interpreter. The directory/zipfile is automatically inserted as the
9272 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009273
Georg Brandl3ee81df2008-05-17 18:14:43 +00009274- Issue #1265: Fix a problem with sys.settrace, if the tracing
9275 function uses a generator expression when at the same time the
9276 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009277
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009278- sets and frozensets now have an isdisjoint() method.
9279
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009280- optimize the performance of builtin.sum().
9281
Neal Norwitz44f326e2007-10-05 05:29:17 +00009282- Fix warnings found by the new version of the Coverity checker.
9283
Georg Brandl21e99f42010-03-07 15:23:59 +00009284- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9286 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009287
Georg Brandl3ee81df2008-05-17 18:14:43 +00009288- Issue #1686386: Tuple's tp_repr did not take into account the
9289 possibility of having a self-referential tuple, which is possible
9290 from C code. Nor did object's tp_str consider that a type's tp_str
9291 could do something that could lead to an inifinite recursion.
9292 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9293 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009294
Georg Brandl3ee81df2008-05-17 18:14:43 +00009295- Issue #1164: It was possible to trigger deadlock when using the
9296 'print' statement to write to a file since the GIL was not released
9297 as needed. Now PyObject_Print() does the right thing along with
9298 various tp_print implementations of the built-in types and those in
9299 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009300
Georg Brandl3ee81df2008-05-17 18:14:43 +00009301- Issue #1147: Exceptions were directly allowing string exceptions in
9302 their throw() method even though string exceptions no longer
9303 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009304
Georg Brandl3ee81df2008-05-17 18:14:43 +00009305- Issue #1096: Prevent a segfault from getting the repr of a very
9306 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009307
Brett Cannon1e534b52007-09-07 04:18:30 +00009308- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009309 PyObject_Call() never calling back out to Python code to trigger
9310 recursion depth updates/checks. Required the creation of a static
9311 RuntimeError instance in case normalizing an exception put the
9312 recursion check value past its limit. Fixes crashers
9313 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009314
Georg Brandl3ee81df2008-05-17 18:14:43 +00009315- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009328- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009329 __*__ attributes. (Some already existed, e.g., __doc__ and
9330 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009331
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009332- Add -3 option to the interpreter to warn about features that are
9333 deprecated and will be changed/removed in Python 3.0.
9334
Georg Brandl2134e752007-05-21 20:34:16 +00009335- Patch #1686487: you can now pass any mapping after '**' in function
9336 calls.
9337
Collin Winter62903052007-05-18 23:11:24 +00009338- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009339 "except E as target:". This is to provide forwards compatibility
9340 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009341
Brett Cannon229cee22007-05-05 01:34:02 +00009342- Deprecate BaseException.message as per PEP 352.
9343
Georg Brandl3ee81df2008-05-17 18:14:43 +00009344- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009345 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009346
Vinay Sajip8549ce32007-05-06 17:53:37 +00009347- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009348 setting a plain string, ie don't expand to single letter identifiers.
9349
Raymond Hettinger13936692007-04-11 18:40:58 +00009350- Request #1191699: Slices can now be pickled.
9351
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009352- Request #1193128: str.translate() now allows a None argument for
9353 translations that only remove characters without re-mapping the
9354 remaining characters.
9355
Georg Brandl5cb76c12007-03-21 09:00:39 +00009356- Patch #1682205: a TypeError while unpacking an iterable is no longer
9357 masked by a generic one with the message "unpack non-sequence".
9358
Neal Norwitzaa754b72007-03-21 06:39:48 +00009359- Remove unused file Python/fmod.c.
9360
Guido van Rossum143b5642007-03-23 04:58:42 +00009361- Bug #1683368: The object.__init__() and object.__new__() methods are
9362 now stricter in rejecting excess arguments. The only time when
9363 either allows excess arguments is when it is not overridden and the
9364 other one is. For backwards compatibility, when both are
9365 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009366 warning later). Also, type.__init__() insists on the same signature
9367 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009368
Georg Brandl3ee81df2008-05-17 18:14:43 +00009369- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9370 object to complex using its __complex__() method before falling back
9371 to the __float__() method. Therefore, the functions in the cmath
9372 module now can operate on objects that define a __complex__()
9373 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009374
Georg Brandl3ee81df2008-05-17 18:14:43 +00009375- Patch #1623563: allow __class__ assignment for classes with
9376 __slots__. The old and the new class are still required to have the
9377 same slot names.

9383 ``object.__reduce_ex__()`` is called with an object that is faking
9384 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009385
Georg Brandl3ee81df2008-05-17 18:14:43 +00009386- Patch #1680015: Don't modify __slots__ tuple if it contains an

9390
Georg Brandl7b9c5552007-03-12 14:30:05 +00009391- Bug #1678647: write a newline after printing an exception in any
9392 case, even when converting the value to a string failed.
9393
Georg Brandl871f1bc2007-03-12 13:17:36 +00009394- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009395 its argument, if it exists. If not, it will work like before. This
9396 allows customizing the output of dir() in the presence of a
9397 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00009512- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009530 generator expressions (x for x, in ... ) works again. Fixing this
9531 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00009920 the client's request was successfully received, understood, and

9932 work started with create_connection() and timeout in httplib, and
9933 closes patch #723312.
9934
Vinay Sajip8549ce32007-05-06 17:53:37 +00009935- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +000010052- unittest now verifies more of its assumptions. In particular,
10053 TestCase and TestSuite subclasses (not instances) are no longer

10056 -- the failure just occurred later, with a more cumbersome
10057 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010440 time so that opening a database previously created with the DB_DUP
10441 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10442 opens. Specifically: dictionary assignment to a DB object will
10443 replace all values for a given key when the database allows
10444 duplicate values. DB users should use DB.put(k, v) when they want
10445 to store duplicates; not DB[k] = v.

10454 behavior of quoting dots if they are the second character of any
10455 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010864- Removed the macfs module. It had been deprecated since Python 2.5.
10865 This lead to the deprecation of macostools.touched() as it relied
10866 solely on macfs and was a no-op under OS X.
