113
Georg Brandlba83f822010-03-14 09:50:54 +0000114- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
115 a base64 transfer-encoded payload *after* decoding it; it no longer does.

129
Georg Brandlba83f822010-03-14 09:50:54 +0000130- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
131 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
132 argument's __int__ method to convert to an integer before packing. It also
133 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
134 was inconsistent: __int__ was used for some integer codes but not for others,
135 and the set of integer codes for which it was used differed between native
136 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000408 file position when calling `truncate()`. It would previously change the file
409 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000410 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

415 class used to represent files stored inside an archive. The new
416 implementation is significantly faster and can be wrapped in a
417 ``io.BufferedReader`` object for more speedups. It also solves an issue
418 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Petersona43f34c2010-01-25 03:31:13 +0000428
Georg Brandlba83f822010-03-14 09:50:54 +0000429- Issue #7748: Since unicode values are supported for some metadata options in
430 Distutils, the DistributionMetadata get_* methods will now return an utf-8
431 encoded string for them. This ensures that the upload and register commands
432 send the correct values to PyPI without any error.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000703- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
704 decimal string that's guaranteed to round back to x under correct rounding
705 (with round-half-to-even rounding mode). Previously it gave a string based on
706 rounding x to 17 decimal digits. repr(x) for a complex number behaves
707 similarly. On platforms where the correctly-rounded strtod and dtoa code is
708 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000710- Issue #7117: On almost all platforms: float-to-string and string-to-float
711 conversions within Python are now correctly rounded. Places these conversions
712 occur include: str for floats and complex numbers; the float and complex
713 constructors; old-style and new-style numeric formatting; serialization and
714 deserialization of floats and complex numbers using marshal, pickle and json;
715 parsing of float and imaginary literals in Python code; Decimal-to-float
716 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000717
Georg Brandlba83f822010-03-14 09:50:54 +0000718 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
719 providing correctly-rounded strtod and dtoa C functions. This code is
720 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
721 the C compiler. There may be a small number of platforms on which correct
722 operation of this code cannot be guaranteed, so the code is not used: notably,
723 this applies to platforms where the C double format is not IEEE 754 binary64,
724 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
725 and Python's configure script is unable to determine how to change the FPU
726 precision. On these platforms conversions use the platform strtod and dtoa,
727 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000729- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
730 uses the correctly-rounded string <-> float conversions described above (when
731 available), and so produces correctly rounded results that will display nicely
732 under the float repr. There are two related small changes: (1) round now
733 accepts any class with an ``__index__()`` method for its second argument (but
734 no longer accepts floats for the second argument), and (2) an excessively
735 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
736 raises an exception.

885 but with at least one decimal point and with a default precision
886 of 12. Previously, the behavior the same but with a default precision of 6.
887 This more closely matches ``str()``, and reduces surprises when adding

1115 this code path is really executed because I cannot move to such directory on

1142 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1143 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001146- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001149- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Georg Brandlba83f822010-03-14 09:50:54 +00001221- Issue #6816: runpy now provides a run_path function that allows Python code to
1222 execute file paths that refer to source or compiled Python files as well as
1223 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00001224 __main__.py file. This allows applications that run other Python scripts to
1225 support the same flexibility as the CPython command line itself.

1250 from stdin so that existing input does not confuse it and lead to incorrect
1251 entry or an IOError. It also properly flushes it afterwards to avoid the
1252 terminal echoing the input afterwards on OSes such as Solaris.

2518
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002519- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2520 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2521 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2522 ``printf`` function, whereas PyString_FromFormat has an independent
2523 implementation and uses "%zd" on all platforms for size_t values.
2524 This makes a difference on win64, where ``printf`` needs "%Id" to display
2525 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002527- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2531 object; previously an int would be returned for small values. the __long__
2532 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002544- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002545 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2546 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2547 when given a tuple of classes as second argument, were looking up
2548 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2549 type object.

2643
Jesse Noller438195f2009-01-18 21:04:36 +00002644- Issue #4301: Patch the logging module to add processName support, remove
2645 _check_logger_class from multiprocessing.
2646
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002647- Issue #2975: When compiling several extension modules with Visual Studio 2008
2648 from the same python interpreter, some environment variables would grow
2649 without limit.
2650
Benjamin Peterson37346b22008-08-23 20:27:43 +00002651- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2652 exploitation of poor argument checking.
2653
Gerhard Häringef2276b2008-09-12 13:54:06 +00002654- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

2657 remaining ones have "pysqlite_" prefix.
2658
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002659- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2667 wrapper for warnings.catch_warnings() that makes it easier to check
2668 that expected warning messages are being reported.
2669
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002670- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002688What's New in Python 2.6 beta 3?
2689================================
2690
Barry Warsaw07a4a382008-08-21 01:15:08 +00002691*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002692
2693Core and Builtins
2694-----------------
2695
Guido van Rossumf8402962008-08-20 15:01:50 +00002696- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2697 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2698 extensions do not automatically benefit from the class attribute
2699 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2700 to their tp_flags field if they care. This is a backwards
2701 compatibility feature; in 3.0, all types will use the cache by
2702 default.
2703
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002704- Keyword arguments can now follow starred arguments. (``f(a, *args,
2705 keyword=23)`` is now valid syntax.)
2706
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002707- ctypes function pointers that are COM methods have a boolean True
2708 value again.
2709
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002710- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2711 by denying s# to parse objects that have a releasebuffer procedure,
2712 and introducing s*.
2713
Georg Brandl1e13ea92008-08-11 09:07:59 +00002714- Issue #3537: Fix an assertion failure when an empty but presized dict
2715 object was stored in the freelist.
2716
Mark Dickinsonb6467572008-08-04 21:30:09 +00002717- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2718 ValueError consistently across platforms.
2719
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002720- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2721 (64bit Unix, for example), unichr() would truncate its argument and return
2722 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2723
Neal Norwitze7d8be82008-07-31 17:17:14 +00002724- Apply security patches from Apple.
2725
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002726- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2727 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2728
Antoine Pitrou92f82162008-07-25 22:22:08 +00002729- Issue #1819: function calls with several named parameters are now on
2730 average 35% faster (as measured by pybench).
2731
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002732- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2733 the python debugger steps into a class statement: the free variables (local
2734 variables defined in an outer scope) would be deleted from the outer scope.
2735
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002736- Issue #2620: Overflow checking when allocating or reallocating memory
2737 was not always being done properly in some python types and extension
2738 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2739 all been updated to perform better checks and places in the code that
2740 would previously leak memory on the error path when such an allocation
2741 failed have been fixed.
2742
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002743Library
2744-------
2745
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002746- Issue #3612: Added some missing basic types in ctypes.wintypes.
2747
Benjamin Petersone977ad42008-08-20 01:42:01 +00002748- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2749 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2750
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002751- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2752 version reported by these tools does not necessarily follow the python
2753 version numbering scheme, so the module is less strict when parsing it.
2754
Nick Coghlanf70385a2008-08-18 12:42:46 +00002755- Issue #2235: Added Py3k warnings for types which will become unhashable
2756 under the stricter __hash__ inheritance rules in 3.0. Several types
2757 which did not meet the rules for hash invariants and were already
2758 unhashable in 3.0 have now been explicitly flagged as unhashable in
2759 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2760 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2761
Brett Cannon88f801d2008-08-18 00:46:22 +00002762- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2763 imported into the module but exposed as part of the module's API.
2764
Brett Cannon7b96f072008-08-18 00:41:11 +00002765- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2766
Brett Cannon46225e72008-08-18 00:36:52 +00002767- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2768
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002769- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2770
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002771- Issue #3575: Incremental decoder's decode function now takes bytearray
2772 by using 's*' instead of 't#'.
2773
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002774- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002775 fails unicode conversion on 2nd parameter. (windows only)
2776
Facundo Batista94f243a2008-08-17 03:38:39 +00002777- Issue 2464. urllib2 now supports a malformation in the URL received
2778 in a redirect.
2779
Brett Cannonabe423e2008-08-16 21:47:07 +00002780- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002781 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002782
Facundo Batistaeb90b782008-08-16 14:44:07 +00002783- Issue #2776: fixed small issue when handling an URL with double slash
2784 after a 302 response in the case of not going through a proxy.
2785
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002786- Issue #2676: in the email package, content-type parsing was hanging on
2787 pathological input because of quadratic or exponential behaviour of a
2788 regular expression.
2789
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002790- Issue #3476: binary buffered reading through the new "io" library is now
2791 thread-safe.
2792
Brett Cannonbf3157b2008-08-14 05:00:03 +00002793- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2794 since mimetools itself is deprecated. Because modules are cached, all
2795 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2796
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002797- Issue #3134: shutil referenced undefined WindowsError symbol.
2798
Robert Schuppenies14646332008-08-10 11:01:53 +00002799- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2800 menu entries were not deleted.
2801
Brett Cannon83e81842008-08-09 23:30:55 +00002802- Copied the implementation of reduce() to _functools.reduce() to have a
2803 version that did not raise a DeprecationWarning under -3.
2804
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002805- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2806 a MemoryError rather than silently stop the iteration.
2807
Guido van Rossum59ce9012008-08-09 14:55:34 +00002808- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2809 to _sre.compile() will now be rejected. This should not affect anybody
2810 since the re.compile() function never generates invalid re-bytecode.
2811
Skip Montanaroa032bf42008-08-08 22:52:51 +00002812- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2813 upon first access it can be automatically initialized from the csv file if
2814 it wasn't initialized during instantiation.
2815
Brett Cannon3aa2a492008-08-06 22:28:09 +00002816- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2817 the reload() built-in has been removed.
2818
Brett Cannon7e30b672008-08-04 21:52:25 +00002819- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002820 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2823 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2824 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2825 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

2828 raised an AttributeError.
2829
Benjamin Peterson01a24322008-07-28 23:35:27 +00002830- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002831 asking for a specific length. This problem only affected files opened
2832 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002833
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002834- Issue #3449: Update decimal module to use most recent specification
2835 (v. 1.68) and tests (v. 2.58) from IBM.
2836
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002837- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2838

2845
2846- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2847 invalid arguments.
2848
2849- Issue #3302: Fix several crashes when calling locale's gettext functions
2850 with None arguments.
2851
2852- Issue #3389: Allow resolving dotted names for handlers in logging
2853 configuration files.
2854
2855- Deprecate the sunaudio module for removal in Python 3.0.
2856
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002857- Issue #3394: zipfile.writestr sets external attributes when passed a
2858 file name rather than a ZipInfo instance, so files are extracted with
2859 mode 0600 rather than 000 under Unix.
2860
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002861- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2862 argument in python 2.5, this broke code that subclassed Popen to include its
2863 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2871-------------
2872
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002873- Issue #2235: the C API function PyObject_HashNotImplemented and its
2874 interaction with the tp_hash slot (added in 2.6b2) are now documented
2875
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002876- Issue #643841: The language reference now provides more detailed
2877 coverage of the lookup process for special methods. The disclaimers
2878 regarding lack of coverage of new-style classes have also been
2879 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002882What's New in Python 2.6 beta 2?
2883================================
2884
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002885*Release date: 17-Jul-2008*
2886
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002887Core and Builtins
2888-----------------
2889
Georg Brandl3e483f62008-07-16 22:57:41 +00002890- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2891 its methods now allow for items objects that can be converted to
2892 an integer using operator.index().
2893
Mark Dickinson64b7e502008-07-16 09:40:03 +00002894- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2895 produced a ValueError instead of giving the correct float.
2896
Eric Smitha5fa5a22008-07-16 00:11:49 +00002897- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2898 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2899
Mark Dickinson7103aa42008-07-15 19:08:33 +00002900- Issue #3008: the float type has a new instance method 'float.hex'
2901 and a new class method 'float.fromhex' to convert floating-point
2902 numbers to and from hexadecimal strings, respectively.
2903
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002904- Issue #2235: __hash__ is once again inherited by default. To allow
2905 collections.Hashable to remain meaningful in the presence of the
2906 default hash implementation (object.__hash__), it is now possible
2907 to explicit block inheritance of hash by setting __hash__=None at
2908 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2909 level.
2910
Nick Coghlanb028f502008-07-13 14:52:36 +00002911- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2912 the parent module cannot be found while performing an absolute import.
2913 This means that an incorrectly defined __package__ attribute will
2914 now only prevent relative imports in that module rather than causing
2915 all imports from that module to fail.
2916
Nick Coghlan14ff9942008-07-08 14:21:42 +00002917- Issue #2517: Allow unicode messages in Exceptions again by correctly
2918 bypassing the instance dictionary when looking up __unicode__ on
2919 new-style classes.
2920
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002921- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2922 set to a custom object whose write() method happens to install
2923 another file in sys.stdout.
2924
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002925- Issue #3088: Corrected a race condition in classes derived from

2927 another thread's dictionary.
2928
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002929- Issue #3004: Minor change to slice.indices(): the start and stop
2930 arguments are now treated identically, making the behaviour easier

Georg Brandl5cc774e2008-06-11 20:28:06 +00003388 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003389
3390 This is controlled by the configure argument ``--with-universal-archs``:

3437 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Issue #1631171: Re-implement the 'warnings' module in C (the
3451 original Python code has been kept as backup). This will allow for
3452 using the 'warning's machinery in such places as the parser where
3453 use of pure Python code is not possible. Both the ``showarning()``
3454 and ``formatwarning()`` gain an optional 'line' argument which is
3455 not called by default for backwards-compatibility reasons. Setting
3456 ``warnings.showwarning()`` to an implementation that lacks support
3457 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Issue #2550: The approach used by client/server code for obtaining
3521 ports to listen on in network-oriented tests has been refined in an
3522 effort to facilitate running multiple instances of the entire
3523 regression test suite in parallel without issue.
3524 test_support.bind_port() has been fixed such that it will always
3525 return a unique port -- which wasn't always the case with the
3526 previous implementation, especially if socket options had been set
3527 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3528 new implementation of bind_port() will actually raise an exception
3529 if it is passed an AF_INET/SOCK_STREAM socket with either the
3530 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3531 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3532 the socket it's been passed. This currently only applies to
3533 Windows. This option prevents any other sockets from binding to the
3534 host/port we've bound to, thus removing the possibility of the
3535 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3536 when a second SOCK_STREAM socket binds and accepts to a host/port
3537 that's already been bound by another socket. The optional preferred
3538 port parameter to bind_port() has been removed. Under no
3539 circumstances should tests be hard coding ports!
3540
3541 test_support.find_unused_port() has also been introduced, which will
3542 pass a temporary socket object to bind_port() in order to obtain an
3543 unused port. The temporary socket object is then closed and
3544 deleted, and the port is returned. This method should only be used
3545 for obtaining an unused port in order to pass to an external program
3546 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3547 a parameter to a server-oriented class that doesn't give you direct
3548 access to the underlying socket used.
3549
3550 Finally, test_support.HOST has been introduced, which should be used
3551 for the host argument of any relevant socket calls (i.e. bind and
3552 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003553
3554 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003556 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3557 test_asynchat and test_socket_ssl.
3558
Georg Brandl3ee81df2008-05-17 18:14:43 +00003559 It is now possible for multiple instances of the regression test
3560 suite to run in parallel without issue.

3828
Fred Drakea8ee94b2008-03-01 02:45:07 +00003829- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003830 644. The mode is now inherited from the py file.

3833
3834- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003835
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003836- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003837 issue 215555 for a discussion.
3838
Eric Smitha73fbe72008-02-23 03:09:44 +00003839- Added the future_builtins module, which contains hex() and oct().
3840 These are the PEP 3127 version of these functions, designed to be
3841 compatible with the hex() and oct() builtins from Python 3.0. They
3842 differ slightly in their output formats from the existing, unchanged
3843 Python 2.6 builtins. The expected usage of the future_builtins
3844 module is:
3845 from future_builtins import hex, oct
3846
Eric Smith7ef40bf2008-02-20 23:34:22 +00003847- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3848 exponents for exponents with absolute value < 100. Follows C99
3849 standard. This is a change on Windows, which would use 3 digits.
3850 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3851 so that any alterations it does to the resulting string will be
3852 available in stringlib/formatter.h (for float.__format__).
3853
Eric Smith5a3c1352008-02-19 13:21:56 +00003854- Implemented PEP 3101, Advanced String Formatting. This adds a new
3855 builtin format(); a format() method for str and unicode; a
3856 __format__() method to object, str, unicode, int, long, float, and
3857 datetime; the class string.Formatter; and the C API
3858 PyObject_Format().
3859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Fixed several potential crashes, all caused by specially crafted
3861 __del__ methods exploiting objects in temporarily inconsistent
3862 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003863
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003864- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003865 prevent a possible crash: an Abstract Base Class would try to access
3866 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Clear all free lists during a gc.collect() of the highest generation
3872 in order to allow pymalloc to free more arenas. Python may give back
3873 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003874
Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Issue #2045: Fix an infinite recursion triggered when printing a
3876 subclass of collections.defaultdict, if its default_factory is set
3877 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003878
Christian Heimesf75dbef2008-02-08 00:11:31 +00003879- Fixed a minor memory leak in dictobject.c. The content of the free
3880 list was not freed on interpreter shutdown.
3881
Georg Brandl21e99f42010-03-07 15:23:59 +00003882- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003884
Georg Brandl3ee81df2008-05-17 18:14:43 +00003885- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3886 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003887 to compact the internal free lists of pre-allocted ints and floats.
3888
Georg Brandl3ee81df2008-05-17 18:14:43 +00003889- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3890 calls. Python expected the return type int but the fork familie
3891 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003892
Georg Brandl3ee81df2008-05-17 18:14:43 +00003893- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3894 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003895
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3897 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3903 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- Patch #1473257: generator objects gain a gi_code attribute. This is
3906 the same object as the func_code attribute of the function that
3907 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Issue #1920: "while 0" statements were completely removed by the
3910 compiler, even in the presence of an "else" clause, which is
3911 supposed to be run when the condition is false. Now the compiler
3912 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003913
Guido van Rossumeead05f2008-01-24 18:21:02 +00003914- A few crashers fixed: weakref_in_del.py (issue #1377858);
3915 loosing_dict_ref.py (issue #1303614, test67.py);
3916 borrowed_ref_[34].py (not in tracker).
3917
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003918- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003919 suppressed while an extension is loaded by calling SetErrorMode in
3920 dynload_win.c. The error is still reported properly.
3921
Georg Brandl3ee81df2008-05-17 18:14:43 +00003922- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003923 several extension methods and modules do not work without unicode
3924 support.
3925
Georg Brandl26543b12008-01-21 18:36:51 +00003926- Issue #1882: when compiling code from a string, encoding cookies in the
3927 second line of code were not always recognized correctly.
3928
Georg Brandl14404b62008-01-19 19:27:05 +00003929- Issue #1679: "0x" was taken as a valid integer literal.
3930
Georg Brandl6caad7d2008-01-26 14:19:22 +00003931- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003932 added.
3933
Christian Heimesc94e2b52008-01-14 04:13:37 +00003934- sys.float_info / PyFloat_GetInfo: The floating point information
3935 object was converted from a dict to a specialized structseq object.
3936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937- Patch #1816: Added sys.flags structseq. It exposes the status of
3938 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003939
Georg Brandl3ee81df2008-05-17 18:14:43 +00003940- Objects/structseq.c: Implemented new structseq representation. The
3941 patch makes structseqs (e.g. the return value of os.stat) more
3942 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003943
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944- Patch #1700288: added a type attribute cache that caches method

3953 envvar and sys.dont_write_bytecode attribute. All these can be set
3954 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003955
Georg Brandl3ee81df2008-05-17 18:14:43 +00003956- Improve some exception messages when Windows fails to load an
3957 extension module. Now we get for example '%1 is not a valid Win32
3958 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 and INF. float("nan"), float("inf") and float("-inf") now work on
3967 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003968
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969- Compiler now generates simpler and faster code for dictionary
3970 literals. The oparg for BUILD_MAP now indicates an estimated
3971 dictionary size. There is a new opcode, STORE_MAP, for adding
3972 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Patch #1739468: Directories and zipfiles containing a __main__.py
4002 file can now be directly executed by passing their name to the
4003 interpreter. The directory/zipfile is automatically inserted as the
4004 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004005
Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Issue #1265: Fix a problem with sys.settrace, if the tracing
4007 function uses a generator expression when at the same time the
4008 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004009
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004010- sets and frozensets now have an isdisjoint() method.

4015
Georg Brandl21e99f42010-03-07 15:23:59 +00004016- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4018 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004019
Georg Brandl3ee81df2008-05-17 18:14:43 +00004020- Issue #1686386: Tuple's tp_repr did not take into account the
4021 possibility of having a self-referential tuple, which is possible
4022 from C code. Nor did object's tp_str consider that a type's tp_str
4023 could do something that could lead to an inifinite recursion.
4024 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4025 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Issue #1164: It was possible to trigger deadlock when using the
4028 'print' statement to write to a file since the GIL was not released
4029 as needed. Now PyObject_Print() does the right thing along with
4030 various tp_print implementations of the built-in types and those in
4031 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004032
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Issue #1147: Exceptions were directly allowing string exceptions in
4034 their throw() method even though string exceptions no longer
4035 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004037- Issue #1096: Prevent a segfault from getting the repr of a very
4038 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004039
Brett Cannon1e534b52007-09-07 04:18:30 +00004040- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041 PyObject_Call() never calling back out to Python code to trigger
4042 recursion depth updates/checks. Required the creation of a static
4043 RuntimeError instance in case normalizing an exception put the
4044 recursion check value past its limit. Fixes crashers
4045 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004046

Neal Norwitz0ac60192007-05-27 04:08:54 +00004060- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061 __*__ attributes. (Some already existed, e.g., __doc__ and
4062 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004063
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004064- Add -3 option to the interpreter to warn about features that are
4065 deprecated and will be changed/removed in Python 3.0.
4066
Georg Brandl2134e752007-05-21 20:34:16 +00004067- Patch #1686487: you can now pass any mapping after '**' in function
4068 calls.
4069
Collin Winter62903052007-05-18 23:11:24 +00004070- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071 "except E as target:". This is to provide forwards compatibility
4072 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004076- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004077 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004078
Vinay Sajip8549ce32007-05-06 17:53:37 +00004079- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004080 setting a plain string, ie don't expand to single letter identifiers.
4081
Raymond Hettinger13936692007-04-11 18:40:58 +00004082- Request #1191699: Slices can now be pickled.
4083
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004084- Request #1193128: str.translate() now allows a None argument for
4085 translations that only remove characters without re-mapping the
4086 remaining characters.
4087
Georg Brandl5cb76c12007-03-21 09:00:39 +00004088- Patch #1682205: a TypeError while unpacking an iterable is no longer

4092
Guido van Rossum143b5642007-03-23 04:58:42 +00004093- Bug #1683368: The object.__init__() and object.__new__() methods are
4094 now stricter in rejecting excess arguments. The only time when
4095 either allows excess arguments is when it is not overridden and the
4096 other one is. For backwards compatibility, when both are
4097 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004098 warning later). Also, type.__init__() insists on the same signature
4099 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4102 object to complex using its __complex__() method before falling back
4103 to the __float__() method. Therefore, the functions in the cmath
4104 module now can operate on objects that define a __complex__()
4105 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Patch #1623563: allow __class__ assignment for classes with
4108 __slots__. The old and the new class are still required to have the
4109 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004110

4115 ``object.__reduce_ex__()`` is called with an object that is faking
4116 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Patch #1680015: Don't modify __slots__ tuple if it contains an

4122
Georg Brandl7b9c5552007-03-12 14:30:05 +00004123- Bug #1678647: write a newline after printing an exception in any
4124 case, even when converting the value to a string failed.
4125
Georg Brandl871f1bc2007-03-12 13:17:36 +00004126- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127 its argument, if it exists. If not, it will work like before. This
4128 allows customizing the output of dir() in the presence of a
4129 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004131- Patch #922167: Python no longer segfaults when faced with infinitely
4132 self-recursive reload() calls (as reported by bug #742342).
4133

Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Patch #1491866: change the complex() constructor to allow
4138 parthensized forms. This means complex(repr(x)) now works instead of
4139 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004140
Georg Brandlaa2321b2007-03-07 00:40:28 +00004141- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 makes the filenames the warning module prints much more sensible
4143 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004144
Georg Brandl49aafc92007-03-07 00:34:46 +00004145- Variant of patch #697613: don't exit the interpreter on a SystemExit
4146 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl098cd692007-03-06 12:17:50 +00004155
Georg Brandl0fca97a2007-03-05 22:28:08 +00004156- Patch #1674228: when assigning a slice (old-style), check for the
4157 sq_ass_slice instead of the sq_slice slot.
4158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- When printing an unraisable error, don't print exceptions. before
4160 the name. This duplicates the behavior whening normally printing
4161 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Bug #1653736: Properly discard third argument to

4727
Georg Brandl92a6bae2007-03-13 17:43:32 +00004728- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004729 are set for invalid interpolation sequences that would lead to

4786 TestCase and TestSuite subclasses (not instances) are no longer
4787 accepted in TestSuite.addTest(). This should cause no
4788 incompatibility since it never made sense with ordinary subclasses
4789 -- the failure just occurred later, with a more cumbersome
4790 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005071- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5072 with RFC 3207 and forgets any knowledge obtained from the server not
5073 obtained from the TLS negotiation itself. Patch contributed by Bill
5074 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005075
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005077 that the SMTP.starttls() caller no longer needs to call ehlo()
5078 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005079 does not claim to support starttls. Adds the
5080 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005135- itertools.chain() now has an alternate constructor,

5161 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5162 silently miscode subclasses of those types. Now, it raises a
5163 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005164

Georg Brandl3ee81df2008-05-17 18:14:43 +00005179 time so that opening a database previously created with the DB_DUP
5180 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5181 opens. Specifically: dictionary assignment to a DB object will
5182 replace all values for a given key when the database allows
5183 duplicate values. DB users should use DB.put(k, v) when they want
5184 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005185

5191 characters with ASCII value less than 32. Also, it correctly quotes
5192 dots only if they occur on a single line, as opposed to the previous
5193 behavior of quoting dots if they are the second character of any
5194 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005195

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005463- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005464 periodic threadstate and signal checking in tight loops. By
5465 default, this option is turned-off. It should only be enabled in
5466 debugged, performance critical applications.

5518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Unified naming convention for free lists and their limits. All free
5520 lists in Object/ are named ``free_list``, the counter ``numfree``

5522 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005523
Georg Brandl3ee81df2008-05-17 18:14:43 +00005524- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5525 to ``PyTuple_SetItem``, it can be used to populate a brand new

5538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5540 of w# format code incorrectly truncated the length to an int, even
5541 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5542 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005543
Georg Brandl3ee81df2008-05-17 18:14:43 +00005544- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5564
5565- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5566 outside of pystate.c and should not be necessary.
5567
Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5569 absolute imports. In earlier versions they might have used relative
5570 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005571
Georg Brandl3ee81df2008-05-17 18:14:43 +00005572- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5573 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005574
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005600- Removed the macfs module. It had been deprecated since Python 2.5.
5601 This lead to the deprecation of macostools.touched() as it relied
5602 solely on macfs and was a no-op under OS X.
