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

Ned Deily0d0ea482012-02-10 12:59:06 +0100825- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
826 Distutils-based packages with C extension modules may fail because
827 Apple has removed gcc-4.2, the version used to build python.org
828 64-bit/32-bit Pythons. If the user does not explicitly override
829 the default C compiler by setting the CC environment variable,
830 Distutils will now attempt to compile extension modules with clang
831 if gcc-4.2 is required but not found. Also as a convenience, if
832 the user does explicitly set CC, substitute its value as the default
833 compiler in the Distutils LDSHARED configuration variable for OS X.
834 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
835 SDK, neither of which are available in Xcode 4. This change does not
836 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001109- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1110 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1111 interpreter process. This could cause failures in non-Distutils subprocesses
1112 and was unreliable since tests or user programs could modify the interpreter
1113 environment after Distutils set it. Instead, have Distutils set the the
1114 deployment target only in the environment of each build subprocess. It is
1115 still possible to globally override the default by setting
1116 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1117 greater or equal to the default value, the value with which the interpreter
1118 was built.

1148 the ticker doesn't have to wind down to zero from the old starting point
1149 before the new interval takes effect. And if the user increases the
1150 interval, it makes sure the new limit takes effect right away rather have an
1151 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002102- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2103 This prevents user-created self-referencing ordered dictionaries from
2104 becoming permanently uncollectable GC garbage. The downside is that
2105 removing __del__ means that the internal doubly-linked list has to wait for
2106 GC collection rather than freeing memory immediately when the refcnt drops
2107 to zero.
2108

2139 character years even if the message contains RFC822 two character years.

2175 when the underlying raw IO channel was e.g. a socket. Report and original
2176 patch by Jason V. Miller.

2569 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2570 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002952- Issue #7301: Add environment variable $PYTHONWARNINGS.
2953
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002954- Issue #8329: Don't return the same lists from select.select when no fds are
2955 changed.
2956
Georg Brandlfee0f442010-05-22 21:26:21 +00002957- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

2966
Georg Brandlfee0f442010-05-22 21:26:21 +00002967- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2968 with a non-empty format string. This is an effort to future-proof user
2969 code. If a derived class does not currently implement __format__ but later
2970 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002971 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002972 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003005- Issue #8257: The Decimal construct now accepts a float instance directly,
3006 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003007

3010
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003011- collections.Counter() now supports a subtract() method.

Georg Brandlfee0f442010-05-22 21:26:21 +00003013- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00003022- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3023 InvalidOperation instead of returning False. (Comparisons involving a quiet
3024 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3025 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003026
Georg Brandlfee0f442010-05-22 21:26:21 +00003027- Issue #2531: Comparison operations between floats and Decimal instances now
3028 return a result based on the numeric values of the operands; previously they
3029 returned an arbitrary result based on the relative ordering of id(float) and
3030 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003031
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003032- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003033 argument `-` which tells it to read files to compile from stdin. Each line is
3034 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003044- Comparisons using one of <, <=, >, >= between a complex instance and a
3045 Fractions instance now raise TypeError instead of returning True/False. This
3046 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3047 <=> complex, and complex <=> complex comparisons.

3410 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3411 returning NULL. The macro now returns a statically allocated empty string
3412 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003465 file position when calling `truncate()`. It would previously change the file
3466 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003467 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3470 class used to represent files stored inside an archive. The new
3471 implementation is significantly faster and can be wrapped in a

3473 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003484- Issue #7748: Since unicode values are supported for some metadata options in
3485 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3486 encoded string for them. This ensures that the upload and register commands
3487 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003570- Issue #5080: A number of functions and methods previously produced a

3572 These functions and methods now raise TypeError instead. The majority of the
3573 effects of this change are in the extension modules, but some core functions
3574 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3575 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003758- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3759 decimal string that's guaranteed to round back to x under correct rounding
3760 (with round-half-to-even rounding mode). Previously it gave a string based on
3761 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3762 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3763 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003764
Georg Brandlba83f822010-03-14 09:50:54 +00003765- Issue #7117: On almost all platforms: float-to-string and string-to-float
3766 conversions within Python are now correctly rounded. Places these conversions
3767 occur include: str for floats and complex numbers; the float and complex
3768 constructors; old-style and new-style numeric formatting; serialization and
3769 deserialization of floats and complex numbers using marshal, pickle and json;
3770 parsing of float and imaginary literals in Python code; Decimal-to-float
3771 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003772
Georg Brandlba83f822010-03-14 09:50:54 +00003773 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3774 providing correctly-rounded strtod and dtoa C functions. This code is
3775 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3776 the C compiler. There may be a small number of platforms on which correct
3777 operation of this code cannot be guaranteed, so the code is not used: notably,
3778 this applies to platforms where the C double format is not IEEE 754 binary64,
3779 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3780 and Python's configure script is unable to determine how to change the FPU
3781 precision. On these platforms conversions use the platform strtod and dtoa,
3782 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003784- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3785 uses the correctly-rounded string <-> float conversions described above (when
3786 available), and so produces correctly rounded results that will display nicely
3787 under the float repr. There are two related small changes: (1) round now
3788 accepts any class with an ``__index__()`` method for its second argument (but
3789 no longer accepts floats for the second argument), and (2) an excessively
3790 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3791 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004168- On windows, ``os.chdir()`` given unicode was not working if
4169 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4170 this code path is really executed because I cannot move to such directory on
4171 win2k)

4197 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005574- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5575 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5576 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5577 ``printf`` function, whereas PyString_FromFormat has an independent
5578 implementation and uses "%zd" on all platforms for size_t values.
5579 This makes a difference on win64, where ``printf`` needs "%Id" to display
5580 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005600 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

5603 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5604 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005675 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5676 for catch_warnings() also led to an improvement in the raising of a
5677 DeprecationWarning related to warnings.warn_explicit().
5678
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005679- The deprecation warnings for the old camelCase threading API were removed.

5701
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005702- Issue #2975: When compiling several extension modules with Visual Studio 2008
5703 from the same python interpreter, some environment variables would grow
5704 without limit.
5705
Benjamin Peterson37346b22008-08-23 20:27:43 +00005706- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005743What's New in Python 2.6 beta 3?
5744================================
5745
Barry Warsaw07a4a382008-08-21 01:15:08 +00005746*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005747
5748Core and Builtins
5749-----------------
5750
Guido van Rossumf8402962008-08-20 15:01:50 +00005751- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5752 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5753 extensions do not automatically benefit from the class attribute
5754 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5755 to their tp_flags field if they care. This is a backwards
5756 compatibility feature; in 3.0, all types will use the cache by
5757 default.
5758
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005759- Keyword arguments can now follow starred arguments. (``f(a, *args,
5760 keyword=23)`` is now valid syntax.)
5761
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005762- ctypes function pointers that are COM methods have a boolean True
5763 value again.
5764
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005765- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5766 by denying s# to parse objects that have a releasebuffer procedure,
5767 and introducing s*.
5768
Georg Brandl1e13ea92008-08-11 09:07:59 +00005769- Issue #3537: Fix an assertion failure when an empty but presized dict
5770 object was stored in the freelist.
5771
Mark Dickinsonb6467572008-08-04 21:30:09 +00005772- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5773 ValueError consistently across platforms.
5774
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005775- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5776 (64bit Unix, for example), unichr() would truncate its argument and return
5777 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5778
Neal Norwitze7d8be82008-07-31 17:17:14 +00005779- Apply security patches from Apple.
5780
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005781- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5782 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5783
Antoine Pitrou92f82162008-07-25 22:22:08 +00005784- Issue #1819: function calls with several named parameters are now on
5785 average 35% faster (as measured by pybench).
5786
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005787- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5788 the python debugger steps into a class statement: the free variables (local
5789 variables defined in an outer scope) would be deleted from the outer scope.
5790
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005791- Issue #2620: Overflow checking when allocating or reallocating memory
5792 was not always being done properly in some python types and extension
5793 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5794 all been updated to perform better checks and places in the code that
5795 would previously leak memory on the error path when such an allocation
5796 failed have been fixed.

5802
Benjamin Petersone977ad42008-08-20 01:42:01 +00005803- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5804 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5805
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005806- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5807 version reported by these tools does not necessarily follow the python
5808 version numbering scheme, so the module is less strict when parsing it.
5809
Nick Coghlanf70385a2008-08-18 12:42:46 +00005810- Issue #2235: Added Py3k warnings for types which will become unhashable
5811 under the stricter __hash__ inheritance rules in 3.0. Several types
5812 which did not meet the rules for hash invariants and were already
5813 unhashable in 3.0 have now been explicitly flagged as unhashable in
5814 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5815 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5816
Brett Cannon88f801d2008-08-18 00:46:22 +00005817- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5825
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005826- Issue #3575: Incremental decoder's decode function now takes bytearray
5827 by using 's*' instead of 't#'.
5828
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005829- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005830 fails unicode conversion on 2nd parameter. (windows only)
5831
Georg Brandl222e2082010-08-01 22:27:39 +00005832- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005833 in a redirect.
5834
Brett Cannonabe423e2008-08-16 21:47:07 +00005835- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005836 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005837
Facundo Batistaeb90b782008-08-16 14:44:07 +00005838- Issue #2776: fixed small issue when handling an URL with double slash
5839 after a 302 response in the case of not going through a proxy.
5840
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005841- Issue #2676: in the email package, content-type parsing was hanging on
5842 pathological input because of quadratic or exponential behaviour of a
5843 regular expression.
5844
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005845- Issue #3476: binary buffered reading through the new "io" library is now
5846 thread-safe.
5847
Brett Cannonbf3157b2008-08-14 05:00:03 +00005848- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5849 since mimetools itself is deprecated. Because modules are cached, all
5850 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5851
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005852- Issue #3134: shutil referenced undefined WindowsError symbol.
5853
Robert Schuppenies14646332008-08-10 11:01:53 +00005854- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5855 menu entries were not deleted.
5856
Brett Cannon83e81842008-08-09 23:30:55 +00005857- Copied the implementation of reduce() to _functools.reduce() to have a
5858 version that did not raise a DeprecationWarning under -3.
5859
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005860- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5861 a MemoryError rather than silently stop the iteration.
5862
Guido van Rossum59ce9012008-08-09 14:55:34 +00005863- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5864 to _sre.compile() will now be rejected. This should not affect anybody
5865 since the re.compile() function never generates invalid re-bytecode.
5866
Skip Montanaroa032bf42008-08-08 22:52:51 +00005867- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5868 upon first access it can be automatically initialized from the csv file if
5869 it wasn't initialized during instantiation.
5870
Brett Cannon3aa2a492008-08-06 22:28:09 +00005871- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5872 the reload() built-in has been removed.
5873
Brett Cannon7e30b672008-08-04 21:52:25 +00005874- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005875 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005886 asking for a specific length. This problem only affected files opened
5887 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005888

5913 file name rather than a ZipInfo instance, so files are extracted with
5914 mode 0600 rather than 000 under Unix.
5915
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005916- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5933 regarding lack of coverage of new-style classes have also been
5934 removed, since the coverage is now fairly reasonable.

Georg Brandl3e483f62008-07-16 22:57:41 +00005945- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5946 its methods now allow for items objects that can be converted to
5947 an integer using operator.index().
5948
Mark Dickinson64b7e502008-07-16 09:40:03 +00005949- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5950 produced a ValueError instead of giving the correct float.
5951
Eric Smitha5fa5a22008-07-16 00:11:49 +00005952- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

5957 numbers to and from hexadecimal strings, respectively.
5958
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005959- Issue #2235: __hash__ is once again inherited by default. To allow
5960 collections.Hashable to remain meaningful in the presence of the
5961 default hash implementation (object.__hash__), it is now possible
5962 to explicit block inheritance of hash by setting __hash__=None at
5963 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5964 level.
5965
Nick Coghlanb028f502008-07-13 14:52:36 +00005966- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5967 the parent module cannot be found while performing an absolute import.
5968 This means that an incorrectly defined __package__ attribute will
5969 now only prevent relative imports in that module rather than causing
5970 all imports from that module to fail.
5971
Nick Coghlan14ff9942008-07-08 14:21:42 +00005972- Issue #2517: Allow unicode messages in Exceptions again by correctly

5983
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005984- Issue #3004: Minor change to slice.indices(): the start and stop
5985 arguments are now treated identically, making the behaviour easier
5986 to describe and understand. For example, slice(None, -10,
5987 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5988 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5989 10, -1).

6032 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006033 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006505- Issue #1631171: Re-implement the 'warnings' module in C (the
6506 original Python code has been kept as backup). This will allow for
6507 using the 'warning's machinery in such places as the parser where
6508 use of pure Python code is not possible. Both the ``showarning()``
6509 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Issue #2550: The approach used by client/server code for obtaining
6576 ports to listen on in network-oriented tests has been refined in an
6577 effort to facilitate running multiple instances of the entire
6578 regression test suite in parallel without issue.
6579 test_support.bind_port() has been fixed such that it will always
6580 return a unique port -- which wasn't always the case with the
6581 previous implementation, especially if socket options had been set
6582 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6583 new implementation of bind_port() will actually raise an exception
6584 if it is passed an AF_INET/SOCK_STREAM socket with either the
6585 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6586 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6587 the socket it's been passed. This currently only applies to
6588 Windows. This option prevents any other sockets from binding to the
6589 host/port we've bound to, thus removing the possibility of the
6590 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6591 when a second SOCK_STREAM socket binds and accepts to a host/port
6592 that's already been bound by another socket. The optional preferred
6593 port parameter to bind_port() has been removed. Under no
6594 circumstances should tests be hard coding ports!
6595
6596 test_support.find_unused_port() has also been introduced, which will
6597 pass a temporary socket object to bind_port() in order to obtain an
6598 unused port. The temporary socket object is then closed and
6599 deleted, and the port is returned. This method should only be used
6600 for obtaining an unused port in order to pass to an external program
6601 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6602 a parameter to a server-oriented class that doesn't give you direct
6603 access to the underlying socket used.
6604
6605 Finally, test_support.HOST has been introduced, which should be used
6606 for the host argument of any relevant socket calls (i.e. bind and
6607 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006608
6609 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006611 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6612 test_asynchat and test_socket_ssl.
6613
Georg Brandl3ee81df2008-05-17 18:14:43 +00006614 It is now possible for multiple instances of the regression test
6615 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006781- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
6782 values on 32-bit vs. 64-bit python interpreters. Both were correct,
6783 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00006894- Added the future_builtins module, which contains hex() and oct().
6895 These are the PEP 3127 version of these functions, designed to be
6896 compatible with the hex() and oct() builtins from Python 3.0. They
6897 differ slightly in their output formats from the existing, unchanged
6898 Python 2.6 builtins. The expected usage of the future_builtins
6899 module is:
6900 from future_builtins import hex, oct
6901
Eric Smith7ef40bf2008-02-20 23:34:22 +00006902- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6903 exponents for exponents with absolute value < 100. Follows C99
6904 standard. This is a change on Windows, which would use 3 digits.
6905 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6906 so that any alterations it does to the resulting string will be
6907 available in stringlib/formatter.h (for float.__format__).
6908
Eric Smith5a3c1352008-02-19 13:21:56 +00006909- Implemented PEP 3101, Advanced String Formatting. This adds a new
6910 builtin format(); a format() method for str and unicode; a
6911 __format__() method to object, str, unicode, int, long, float, and
6912 datetime; the class string.Formatter; and the C API
6913 PyObject_Format().
6914
Georg Brandl3ee81df2008-05-17 18:14:43 +00006915- Fixed several potential crashes, all caused by specially crafted
6916 __del__ methods exploiting objects in temporarily inconsistent
6917 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006918
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006919- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920 prevent a possible crash: an Abstract Base Class would try to access
6921 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006922

Georg Brandl3ee81df2008-05-17 18:14:43 +00006926- Clear all free lists during a gc.collect() of the highest generation
6927 in order to allow pymalloc to free more arenas. Python may give back
6928 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006929
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- Issue #2045: Fix an infinite recursion triggered when printing a
6931 subclass of collections.defaultdict, if its default_factory is set
6932 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006933
Christian Heimesf75dbef2008-02-08 00:11:31 +00006934- Fixed a minor memory leak in dictobject.c. The content of the free
6935 list was not freed on interpreter shutdown.
6936
Georg Brandl21e99f42010-03-07 15:23:59 +00006937- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006938 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6941 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006942 to compact the internal free lists of pre-allocted ints and floats.
6943
Georg Brandl3ee81df2008-05-17 18:14:43 +00006944- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6945 calls. Python expected the return type int but the fork familie
6946 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006947
Georg Brandl3ee81df2008-05-17 18:14:43 +00006948- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6958 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Patch #1473257: generator objects gain a gi_code attribute. This is
6961 the same object as the func_code attribute of the function that
6962 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006963
Georg Brandl3ee81df2008-05-17 18:14:43 +00006964- Issue #1920: "while 0" statements were completely removed by the
6965 compiler, even in the presence of an "else" clause, which is
6966 supposed to be run when the condition is false. Now the compiler
6967 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006968
Guido van Rossumeead05f2008-01-24 18:21:02 +00006969- A few crashers fixed: weakref_in_del.py (issue #1377858);
6970 loosing_dict_ref.py (issue #1303614, test67.py);
6971 borrowed_ref_[34].py (not in tracker).
6972
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006973- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006974 suppressed while an extension is loaded by calling SetErrorMode in

6976
Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006978 several extension methods and modules do not work without unicode
6979 support.
6980
Georg Brandl26543b12008-01-21 18:36:51 +00006981- Issue #1882: when compiling code from a string, encoding cookies in the
6982 second line of code were not always recognized correctly.
6983
Georg Brandl14404b62008-01-19 19:27:05 +00006984- Issue #1679: "0x" was taken as a valid integer literal.
6985
Georg Brandl6caad7d2008-01-26 14:19:22 +00006986- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006987 added.
6988
Christian Heimesc94e2b52008-01-14 04:13:37 +00006989- sys.float_info / PyFloat_GetInfo: The floating point information
6990 object was converted from a dict to a specialized structseq object.
6991
Georg Brandl3ee81df2008-05-17 18:14:43 +00006992- Patch #1816: Added sys.flags structseq. It exposes the status of
6993 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006994
Georg Brandl3ee81df2008-05-17 18:14:43 +00006995- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00007021 and INF. float("nan"), float("inf") and float("-inf") now work on
7022 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007024- Compiler now generates simpler and faster code for dictionary
7025 literals. The oparg for BUILD_MAP now indicates an estimated
7026 dictionary size. There is a new opcode, STORE_MAP, for adding
7027 entries to the dictionary.

7039
Nick Coghlanef01d822007-12-03 12:55:17 +00007040- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Patch #1739468: Directories and zipfiles containing a __main__.py
7057 file can now be directly executed by passing their name to the
7058 interpreter. The directory/zipfile is automatically inserted as the
7059 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007061- Issue #1265: Fix a problem with sys.settrace, if the tracing
7062 function uses a generator expression when at the same time the
7063 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007064
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007065- sets and frozensets now have an isdisjoint() method.

7070
Georg Brandl21e99f42010-03-07 15:23:59 +00007071- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007072 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7073 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007074
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Issue #1686386: Tuple's tp_repr did not take into account the
7076 possibility of having a self-referential tuple, which is possible
7077 from C code. Nor did object's tp_str consider that a type's tp_str
7078 could do something that could lead to an inifinite recursion.
7079 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7080 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007081
Georg Brandl3ee81df2008-05-17 18:14:43 +00007082- Issue #1164: It was possible to trigger deadlock when using the
7083 'print' statement to write to a file since the GIL was not released
7084 as needed. Now PyObject_Print() does the right thing along with
7085 various tp_print implementations of the built-in types and those in
7086 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007087
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- Issue #1147: Exceptions were directly allowing string exceptions in
7089 their throw() method even though string exceptions no longer
7090 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007091
Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Issue #1096: Prevent a segfault from getting the repr of a very
7093 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007094
Brett Cannon1e534b52007-09-07 04:18:30 +00007095- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096 PyObject_Call() never calling back out to Python code to trigger
7097 recursion depth updates/checks. Required the creation of a static
7098 RuntimeError instance in case normalizing an exception put the
7099 recursion check value past its limit. Fixes crashers
7100 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007101
Georg Brandl3ee81df2008-05-17 18:14:43 +00007102- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007115- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116 __*__ attributes. (Some already existed, e.g., __doc__ and
7117 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007118
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007119- Add -3 option to the interpreter to warn about features that are
7120 deprecated and will be changed/removed in Python 3.0.
7121
Georg Brandl2134e752007-05-21 20:34:16 +00007122- Patch #1686487: you can now pass any mapping after '**' in function
7123 calls.
7124
Collin Winter62903052007-05-18 23:11:24 +00007125- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126 "except E as target:". This is to provide forwards compatibility
7127 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007128
Brett Cannon229cee22007-05-05 01:34:02 +00007129- Deprecate BaseException.message as per PEP 352.
7130
Georg Brandl3ee81df2008-05-17 18:14:43 +00007131- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007132 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007133
Vinay Sajip8549ce32007-05-06 17:53:37 +00007134- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007135 setting a plain string, ie don't expand to single letter identifiers.
7136
Raymond Hettinger13936692007-04-11 18:40:58 +00007137- Request #1191699: Slices can now be pickled.
7138
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007139- Request #1193128: str.translate() now allows a None argument for
7140 translations that only remove characters without re-mapping the
7141 remaining characters.
7142
Georg Brandl5cb76c12007-03-21 09:00:39 +00007143- Patch #1682205: a TypeError while unpacking an iterable is no longer
7144 masked by a generic one with the message "unpack non-sequence".
7145
Neal Norwitzaa754b72007-03-21 06:39:48 +00007146- Remove unused file Python/fmod.c.
7147
Guido van Rossum143b5642007-03-23 04:58:42 +00007148- Bug #1683368: The object.__init__() and object.__new__() methods are
7149 now stricter in rejecting excess arguments. The only time when
7150 either allows excess arguments is when it is not overridden and the
7151 other one is. For backwards compatibility, when both are
7152 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007153 warning later). Also, type.__init__() insists on the same signature
7154 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007155
Georg Brandl3ee81df2008-05-17 18:14:43 +00007156- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7157 object to complex using its __complex__() method before falling back
7158 to the __float__() method. Therefore, the functions in the cmath
7159 module now can operate on objects that define a __complex__()
7160 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007161
Georg Brandl3ee81df2008-05-17 18:14:43 +00007162- Patch #1623563: allow __class__ assignment for classes with
7163 __slots__. The old and the new class are still required to have the
7164 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007165
Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- Patch #1642547: Fix an error/crash when encountering syntax errors

7170 ``object.__reduce_ex__()`` is called with an object that is faking
7171 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007172
Georg Brandl3ee81df2008-05-17 18:14:43 +00007173- Patch #1680015: Don't modify __slots__ tuple if it contains an

7177
Georg Brandl7b9c5552007-03-12 14:30:05 +00007178- Bug #1678647: write a newline after printing an exception in any
7179 case, even when converting the value to a string failed.
7180
Georg Brandl871f1bc2007-03-12 13:17:36 +00007181- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182 its argument, if it exists. If not, it will work like before. This
7183 allows customizing the output of dir() in the presence of a
7184 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007185
Collin Winter276887b2007-03-12 16:11:39 +00007186- Patch #922167: Python no longer segfaults when faced with infinitely
7187 self-recursive reload() calls (as reported by bug #742342).
7188
Georg Brandl3ee81df2008-05-17 18:14:43 +00007189- Patch #1675981: remove unreachable code from ``type.__new__()``
7190 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007192- Patch #1491866: change the complex() constructor to allow
7193 parthensized forms. This means complex(repr(x)) now works instead of
7194 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007195
Georg Brandlaa2321b2007-03-07 00:40:28 +00007196- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197 makes the filenames the warning module prints much more sensible
7198 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007199
Georg Brandl49aafc92007-03-07 00:34:46 +00007200- Variant of patch #697613: don't exit the interpreter on a SystemExit
7201 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007202 variable is given, but break into the interactive interpreter just
7203 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007210
Georg Brandl0fca97a2007-03-05 22:28:08 +00007211- Patch #1674228: when assigning a slice (old-style), check for the
7212 sq_ass_slice instead of the sq_slice slot.
7213
Georg Brandl3ee81df2008-05-17 18:14:43 +00007214- When printing an unraisable error, don't print exceptions. before
7215 the name. This duplicates the behavior whening normally printing
7216 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007767- Patch #1530482: add pydoc.render_doc() which returns the

7782
Georg Brandl92a6bae2007-03-13 17:43:32 +00007783- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007784 are set for invalid interpolation sequences that would lead to
7785 errors on reading back those values.

7841 TestCase and TestSuite subclasses (not instances) are no longer
7842 accepted in TestSuite.addTest(). This should cause no
7843 incompatibility since it never made sense with ordinary subclasses
7844 -- the failure just occurred later, with a more cumbersome
7845 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008132 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008134 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008233- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234 time so that opening a database previously created with the DB_DUP
8235 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8236 opens. Specifically: dictionary assignment to a DB object will
8237 replace all values for a given key when the database allows
8238 duplicate values. DB users should use DB.put(k, v) when they want
8239 to store duplicates; not DB[k] = v.

8247 dots only if they occur on a single line, as opposed to the previous
8248 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008518- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519 periodic threadstate and signal checking in tight loops. By
8520 default, this option is turned-off. It should only be enabled in
8521 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00008578
Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8580 to ``PyTuple_SetItem``, it can be used to populate a brand new

8593
Georg Brandl3ee81df2008-05-17 18:14:43 +00008594- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8595 of w# format code incorrectly truncated the length to an int, even
8596 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8597 incorrect results with huge strings.

8625 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008626
Georg Brandl3ee81df2008-05-17 18:14:43 +00008627- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8628 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008629
Georg Brandl3ee81df2008-05-17 18:14:43 +00008630- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008655- Removed the macfs module. It had been deprecated since Python 2.5.
8656 This lead to the deprecation of macostools.touched() as it relied
