Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00007What's New in Python 2.7 beta 1?
8================================

12Core and Builtins
13-----------------
14
Tarek Ziadé00002952010-04-03 08:37:59 +000015- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
16
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000017- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
18
Eric Smithd44b2fc2010-04-02 12:30:56 +000019- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
20 is called with a non-empty format string. This is an effort to
21 future-proof user code. If a derived class does not currently
22 implement __format__ but later adds its own __format__, it would
23 most likely break user code that had supplied a format string. This
24 will be changed to a DeprecationWaring in Python 3.3 and it will be
25 an error in Python 3.4.
26
Antoine Pitroua57df2c2010-03-31 21:32:15 +000027- Issue #8268: Old-style classes (not just instances) now support weak
28 references.
29
Victor Stinner6cbf90f2010-03-25 00:21:53 +000030- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
31 optimizations are disabled when --with-pydebug is used.
32
Victor Stinnerc7790ed2010-03-22 12:36:28 +000033- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000034
Benjamin Peterson96545892010-03-21 20:21:00 +000035- Issue #6474: Make error message from passing an inadequate number of keyword
36 arguments to a function correct.
37
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000038- Issue #8164: Don't allow lambda functions to have a docstring.
39
Victor Stinner66644262010-03-10 22:30:19 +000040- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000041 (SIGINT). If an error occurs while importing the site module, the error is
42 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000043 module.
44
Collin Winter001a3952010-03-18 21:54:01 +000045- Code objects now support weak references.

51
Mark Dickinson7c63eee2010-04-02 22:27:36 +000052- Issue #8294: The Fraction constructor now accepts Decimal and float
53 instances directly.
54
Mark Dickinsone096e822010-04-02 10:17:07 +000055- Issue #7279: Comparisons involving a Decimal signaling NaN now
56 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000057 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
58 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000059
Mark Dickinson99d80962010-04-02 08:53:22 +000060- Issue #2531: Comparison operations between floats and Decimal
61 instances now return a result based on the numeric values of the
62 operands; previously they returned an arbitrary result based on
63 the relative ordering of id(float) and id(Decimal).
64
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000065- Issue #8233: When run as a script, py_compile.py optionally takes a single
66 argument `-` which tells it to read files to compile from stdin. Each line
67 is read on demand and the named file is compiled immediately. (Original
68 patch by Piotr Ożarowski).
69
70- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
71 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000072
Florent Xicluna58b65662010-03-30 16:29:03 +000073- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
74 form feed (0x0C) are now considered linebreaks, as specified in Unicode
75 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000076 http://www.unicode.org/reports/tr14/
77
Mark Dickinson9588d992010-03-27 11:14:37 +000078- Comparisons using one of <, <=, >, >= between a complex instance and
79 a Fractions instance now raise TypeError instead of returning
80 True/False. This makes Fraction <=> complex comparisons consistent with
81 int <=> complex, float <=> complex, and complex <=> complex comparisons.
82
Michael Foorde6410c52010-03-29 20:04:23 +000083- Addition of ``WeakSet`` to the ``weakref`` module.

88 running from the build directory (POSIX only).
89
Florent Xiclunae1f4c922010-03-22 22:45:50 +000090- Issue #7667: Fix doctest failures with non-ASCII paths.
91
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000092- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
93 didn't support chflags() (for example ZFS under FreeBSD). The error is
94 now silenced.
95
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000096- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
97 deprecated.
98
R. David Murrayc9d1a782010-03-22 15:55:09 +000099- Issue #7860: platform.uname now reports the correct 'machine' type
100 when Python is running in WOW64 mode on 64 bit Windows.
101
Vinay Sajip804899b2010-03-22 15:29:01 +0000102- logging: Added getChild utility method to Logger and added isEnabledFor
103 method to LoggerAdapter.
104
Vinay Sajip31e928e2010-03-22 13:02:28 +0000105- Issue #8201: logging: Handle situation of non-ASCII and Unicode
106 logger names existing at the same time, causing a Unicode error
107 when configuration code attempted to sort the existing loggers.
108
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000109- Issue #8200: logging: Handle errors when multiprocessing is not
110 fully loaded when logging occurs.
111
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000112- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
113 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
114 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000115
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000116- Issue #8179: Fix macpath.realpath() on a non-existing path.
117
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000118- Issue #8024: Update the Unicode database to 5.2.

128
Matthias Klose358e7ff2010-03-15 13:42:23 +0000129- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
130 the locale.
131
Georg Brandlba83f822010-03-14 09:50:54 +0000132- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000133 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000134 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000135
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000136- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000137 for ``TimedRotatingFileHandler`` by using the modification time of an
138 existing log file to compute the next rollover time. If the log file does
139 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000140

Florent Xicluna47627d52010-03-08 15:20:28 +0000147 classes.
148
Georg Brandlba83f822010-03-14 09:50:54 +0000149- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
150 a base64 transfer-encoded payload *after* decoding it; it no longer does.
151 This is a behavior change, so email's minor version number is now bumped, to
152 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000153

175
Georg Brandlba83f822010-03-14 09:50:54 +0000176- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
177 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
178 argument's __int__ method to convert to an integer before packing. It also
179 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
180 was inconsistent: __int__ was used for some integer codes but not for others,
181 and the set of integer codes for which it was used differed between native
182 packing and standard packing.)

Antoine Pitrou76c86492010-04-01 16:42:11 +0000213- Issue #8276: PyEval_CallObject() is now only available in macro form. The
214 function declaration, which was kept for backwards compatibility reasons,
215 is now removed (the macro was introduced in 1997!).
216
Larry Hastings402b73f2010-03-25 00:54:54 +0000217- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000218 from Python 3.1. All existing Python CObjects in the main distribution
219 have been converted to capsules. To address backwards-compatibility
220 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

426 strings,
427 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
428 numeric strings corresponding to subnormal values,
429 (3) a memory leak for some values large enough to cause overflow, and
430 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +0000466 file position when calling `truncate()`. It would previously change the file
467 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000468 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000487- Issue #7748: Since unicode values are supported for some metadata options in

489 encoded string for them. This ensures that the upload and register commands
490 send the correct values to PyPI without any error.

564Core and Builtins
565-----------------
566
Georg Brandlba83f822010-03-14 09:50:54 +0000567- The ``__complex__()`` method is now looked up on the class of instances to
568 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000569
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000570- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
571 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
572
Mark Dickinson1b34d252010-01-01 17:27:30 +0000573- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000574 DeprecationWarning when passed a float argument where an integer was expected.
575 These functions and methods now raise TypeError instead. The majority of the
576 effects of this change are in the extension modules, but some core functions
577 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
578 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000591- Issue #1811: Improve accuracy and cross-platform consistency for true division
592 of integers: the result of a/b is now correctly rounded for ints a and b (at
593 least on IEEE 754 platforms), and in particular does not depend on the
594 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000595
Georg Brandlba83f822010-03-14 09:50:54 +0000596- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

602
Georg Brandlba83f822010-03-14 09:50:54 +0000603 These executables now work properly with the arch(1) command: ``arch -ppc
604 python`` will start a universal binary version of python in PPC mode (unlike
605 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000606
Georg Brandlba83f822010-03-14 09:50:54 +0000607- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000761- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
762 decimal string that's guaranteed to round back to x under correct rounding
763 (with round-half-to-even rounding mode). Previously it gave a string based on
764 rounding x to 17 decimal digits. repr(x) for a complex number behaves
765 similarly. On platforms where the correctly-rounded strtod and dtoa code is
766 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000768- Issue #7117: On almost all platforms: float-to-string and string-to-float
769 conversions within Python are now correctly rounded. Places these conversions
770 occur include: str for floats and complex numbers; the float and complex
771 constructors; old-style and new-style numeric formatting; serialization and
772 deserialization of floats and complex numbers using marshal, pickle and json;
773 parsing of float and imaginary literals in Python code; Decimal-to-float
774 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000775
Georg Brandlba83f822010-03-14 09:50:54 +0000776 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
777 providing correctly-rounded strtod and dtoa C functions. This code is
778 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
779 the C compiler. There may be a small number of platforms on which correct
780 operation of this code cannot be guaranteed, so the code is not used: notably,
781 this applies to platforms where the C double format is not IEEE 754 binary64,
782 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
783 and Python's configure script is unable to determine how to change the FPU
784 precision. On these platforms conversions use the platform strtod and dtoa,
785 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000787- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
788 uses the correctly-rounded string <-> float conversions described above (when
789 available), and so produces correctly rounded results that will display nicely
790 under the float repr. There are two related small changes: (1) round now
791 accepts any class with an ``__index__()`` method for its second argument (but
792 no longer accepts floats for the second argument), and (2) an excessively
793 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
794 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002371 - Packing a float now always gives a Deprecation Warning. Previously it

2375 struct.error. Previously an x with an __int__ method could be packed by
2376 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2377 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2378 neither __int__ nor __long__, TypeError used to be raised (with a
2379 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2380 struct.error in other cases.

2383 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002577- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2579 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2580 ``printf`` function, whereas PyString_FromFormat has an independent

2678 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2679 for catch_warnings() also led to an improvement in the raising of a
2680 DeprecationWarning related to warnings.warn_explicit().
2681

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002746What's New in Python 2.6 beta 3?
2747================================
2748
Barry Warsaw07a4a382008-08-21 01:15:08 +00002749*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002750
2751Core and Builtins
2752-----------------
2753
Guido van Rossumf8402962008-08-20 15:01:50 +00002754- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2755 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2756 extensions do not automatically benefit from the class attribute
2757 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2758 to their tp_flags field if they care. This is a backwards
2759 compatibility feature; in 3.0, all types will use the cache by
2760 default.
2761
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002762- Keyword arguments can now follow starred arguments. (``f(a, *args,
2763 keyword=23)`` is now valid syntax.)
2764
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002765- ctypes function pointers that are COM methods have a boolean True
2766 value again.
2767
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002768- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2769 by denying s# to parse objects that have a releasebuffer procedure,
2770 and introducing s*.
2771
Georg Brandl1e13ea92008-08-11 09:07:59 +00002772- Issue #3537: Fix an assertion failure when an empty but presized dict
2773 object was stored in the freelist.
2774
Mark Dickinsonb6467572008-08-04 21:30:09 +00002775- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2776 ValueError consistently across platforms.
2777
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002778- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2779 (64bit Unix, for example), unichr() would truncate its argument and return
2780 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2781
Neal Norwitze7d8be82008-07-31 17:17:14 +00002782- Apply security patches from Apple.
2783
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002784- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2785 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2786
Antoine Pitrou92f82162008-07-25 22:22:08 +00002787- Issue #1819: function calls with several named parameters are now on
2788 average 35% faster (as measured by pybench).
2789
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002790- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2791 the python debugger steps into a class statement: the free variables (local
2792 variables defined in an outer scope) would be deleted from the outer scope.
2793
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002794- Issue #2620: Overflow checking when allocating or reallocating memory
2795 was not always being done properly in some python types and extension
2796 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2797 all been updated to perform better checks and places in the code that
2798 would previously leak memory on the error path when such an allocation
2799 failed have been fixed.
2800

2802-------
2803
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002804- Issue #3612: Added some missing basic types in ctypes.wintypes.
2805
Benjamin Petersone977ad42008-08-20 01:42:01 +00002806- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2807 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2808
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002809- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2810 version reported by these tools does not necessarily follow the python
2811 version numbering scheme, so the module is less strict when parsing it.
2812
Nick Coghlanf70385a2008-08-18 12:42:46 +00002813- Issue #2235: Added Py3k warnings for types which will become unhashable
2814 under the stricter __hash__ inheritance rules in 3.0. Several types
2815 which did not meet the rules for hash invariants and were already
2816 unhashable in 3.0 have now been explicitly flagged as unhashable in
2817 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2818 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2819
Brett Cannon88f801d2008-08-18 00:46:22 +00002820- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2824
Brett Cannon46225e72008-08-18 00:36:52 +00002825- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002827- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2828
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002829- Issue #3575: Incremental decoder's decode function now takes bytearray
2830 by using 's*' instead of 't#'.
2831
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002832- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002833 fails unicode conversion on 2nd parameter. (windows only)
2834
Facundo Batista94f243a2008-08-17 03:38:39 +00002835- Issue 2464. urllib2 now supports a malformation in the URL received
2836 in a redirect.
2837
Brett Cannonabe423e2008-08-16 21:47:07 +00002838- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002839 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002840
Facundo Batistaeb90b782008-08-16 14:44:07 +00002841- Issue #2776: fixed small issue when handling an URL with double slash
2842 after a 302 response in the case of not going through a proxy.
2843
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002844- Issue #2676: in the email package, content-type parsing was hanging on
2845 pathological input because of quadratic or exponential behaviour of a
2846 regular expression.
2847
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002848- Issue #3476: binary buffered reading through the new "io" library is now
2849 thread-safe.
2850
Brett Cannonbf3157b2008-08-14 05:00:03 +00002851- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2852 since mimetools itself is deprecated. Because modules are cached, all
2853 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2854
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002855- Issue #3134: shutil referenced undefined WindowsError symbol.
2856
Robert Schuppenies14646332008-08-10 11:01:53 +00002857- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2858 menu entries were not deleted.
2859
Brett Cannon83e81842008-08-09 23:30:55 +00002860- Copied the implementation of reduce() to _functools.reduce() to have a
2861 version that did not raise a DeprecationWarning under -3.
2862
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002863- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2864 a MemoryError rather than silently stop the iteration.
2865
Guido van Rossum59ce9012008-08-09 14:55:34 +00002866- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2867 to _sre.compile() will now be rejected. This should not affect anybody
2868 since the re.compile() function never generates invalid re-bytecode.
2869
Skip Montanaroa032bf42008-08-08 22:52:51 +00002870- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2871 upon first access it can be automatically initialized from the csv file if
2872 it wasn't initialized during instantiation.
2873
Brett Cannon3aa2a492008-08-06 22:28:09 +00002874- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2875 the reload() built-in has been removed.
2876
Brett Cannon7e30b672008-08-04 21:52:25 +00002877- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002878 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2881 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2882 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2883 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00002889 asking for a specific length. This problem only affected files opened
2890 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002891

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002915- Issue #3394: zipfile.writestr sets external attributes when passed a
2916 file name rather than a ZipInfo instance, so files are extracted with
2917 mode 0600 rather than 000 under Unix.
2918
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002919- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2920 argument in python 2.5, this broke code that subclassed Popen to include its

2932 interaction with the tp_hash slot (added in 2.6b2) are now documented
2933
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002934- Issue #643841: The language reference now provides more detailed
2935 coverage of the lookup process for special methods. The disclaimers
2936 regarding lack of coverage of new-style classes have also been
2937 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002940What's New in Python 2.6 beta 2?
2941================================
2942
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002943*Release date: 17-Jul-2008*
2944
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002945Core and Builtins
2946-----------------
2947
Georg Brandl3e483f62008-07-16 22:57:41 +00002948- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2949 its methods now allow for items objects that can be converted to
2950 an integer using operator.index().
2951
Mark Dickinson64b7e502008-07-16 09:40:03 +00002952- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2953 produced a ValueError instead of giving the correct float.
2954
Eric Smitha5fa5a22008-07-16 00:11:49 +00002955- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2956 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2957
Mark Dickinson7103aa42008-07-15 19:08:33 +00002958- Issue #3008: the float type has a new instance method 'float.hex'
2959 and a new class method 'float.fromhex' to convert floating-point
2960 numbers to and from hexadecimal strings, respectively.
2961
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002962- Issue #2235: __hash__ is once again inherited by default. To allow
2963 collections.Hashable to remain meaningful in the presence of the
2964 default hash implementation (object.__hash__), it is now possible
2965 to explicit block inheritance of hash by setting __hash__=None at
2966 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2967 level.
2968
Nick Coghlanb028f502008-07-13 14:52:36 +00002969- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2970 the parent module cannot be found while performing an absolute import.
2971 This means that an incorrectly defined __package__ attribute will
2972 now only prevent relative imports in that module rather than causing
2973 all imports from that module to fail.
2974
Nick Coghlan14ff9942008-07-08 14:21:42 +00002975- Issue #2517: Allow unicode messages in Exceptions again by correctly
2976 bypassing the instance dictionary when looking up __unicode__ on
2977 new-style classes.
2978
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002979- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2980 set to a custom object whose write() method happens to install
2981 another file in sys.stdout.
2982
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002983- Issue #3088: Corrected a race condition in classes derived from
2984 threading.local: the first member set by a thread could be saved in
2985 another thread's dictionary.
2986
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002987- Issue #3004: Minor change to slice.indices(): the start and stop
2988 arguments are now treated identically, making the behaviour easier
2989 to describe and understand. For example, slice(None, -10,
2990 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2991 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2992 10, -1).
2993
Georg Brandl278fc502008-07-19 12:46:12 +00002994- Issue #3219: Calling a function with repeated keyword arguments,
2995 f(a=2, a=23), would not cause a syntax error. This was a regression
2996 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002997
Georg Brandl278fc502008-07-19 12:46:12 +00002998- Issue #2862: Make int and float freelist management consistent with
2999 other freelists. Changes their CompactFreeList apis into
3000 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003005- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3006 api functions without holding the GIL, which could lead to a fatal
3007 error when they failed.
3008
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003009- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3018 ForkingPickler.register() to resolve conflict with ctypes.
3019
Vinay Sajip51e65192008-07-18 09:01:10 +00003020- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003021
Thomas Heller880f5292008-07-15 19:39:38 +00003022- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3023 a valid dlerror() message.
3024
Thomas Heller2bad6572008-07-15 17:19:50 +00003025- Issue #3258: Fixed a crash when a ctypes POINTER type to an

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003033
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003034- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3035 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003036 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003037 content-length. The problem had been corrected in the 2.4 branch, but never
3038 merged into trunk.
3039
Georg Brandle78fbcc2008-07-05 10:13:36 +00003040- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003053- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3054 handling is now the same as that of other special attributes like __name__).
3055
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003056- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3510 using the 'warning's machinery in such places as the parser where
3511 use of pure Python code is not possible. Both the ``showarning()``
3512 and ``formatwarning()`` gain an optional 'line' argument which is
3513 not called by default for backwards-compatibility reasons. Setting
3514 ``warnings.showwarning()`` to an implementation that lacks support
3515 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003578- Issue #2550: The approach used by client/server code for obtaining
3579 ports to listen on in network-oriented tests has been refined in an
3580 effort to facilitate running multiple instances of the entire
3581 regression test suite in parallel without issue.
3582 test_support.bind_port() has been fixed such that it will always
3583 return a unique port -- which wasn't always the case with the
3584 previous implementation, especially if socket options had been set
3585 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3586 new implementation of bind_port() will actually raise an exception
3587 if it is passed an AF_INET/SOCK_STREAM socket with either the
3588 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3589 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3590 the socket it's been passed. This currently only applies to
3591 Windows. This option prevents any other sockets from binding to the
3592 host/port we've bound to, thus removing the possibility of the
3593 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3594 when a second SOCK_STREAM socket binds and accepts to a host/port
3595 that's already been bound by another socket. The optional preferred
3596 port parameter to bind_port() has been removed. Under no
3597 circumstances should tests be hard coding ports!
3598
3599 test_support.find_unused_port() has also been introduced, which will
3600 pass a temporary socket object to bind_port() in order to obtain an
3601 unused port. The temporary socket object is then closed and
3602 deleted, and the port is returned. This method should only be used
3603 for obtaining an unused port in order to pass to an external program
3604 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3605 a parameter to a server-oriented class that doesn't give you direct
3606 access to the underlying socket used.
3607
3608 Finally, test_support.HOST has been introduced, which should be used
3609 for the host argument of any relevant socket calls (i.e. bind and
3610 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003611
3612 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003614 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3615 test_asynchat and test_socket_ssl.
3616
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617 It is now possible for multiple instances of the regression test
3618 suite to run in parallel without issue.

3885-----------------
3886
Fred Drakea8ee94b2008-03-01 02:45:07 +00003887- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003888 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003890- Issue #2067: file.__exit__() now calls subclasses' close() method.
3891
3892- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003893
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003894- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003895 issue 215555 for a discussion.
3896
Eric Smitha73fbe72008-02-23 03:09:44 +00003897- Added the future_builtins module, which contains hex() and oct().
3898 These are the PEP 3127 version of these functions, designed to be
3899 compatible with the hex() and oct() builtins from Python 3.0. They
3900 differ slightly in their output formats from the existing, unchanged
3901 Python 2.6 builtins. The expected usage of the future_builtins
3902 module is:
3903 from future_builtins import hex, oct
3904
Eric Smith7ef40bf2008-02-20 23:34:22 +00003905- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3906 exponents for exponents with absolute value < 100. Follows C99
3907 standard. This is a change on Windows, which would use 3 digits.
3908 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3909 so that any alterations it does to the resulting string will be
3910 available in stringlib/formatter.h (for float.__format__).
3911
Eric Smith5a3c1352008-02-19 13:21:56 +00003912- Implemented PEP 3101, Advanced String Formatting. This adds a new
3913 builtin format(); a format() method for str and unicode; a
3914 __format__() method to object, str, unicode, int, long, float, and
3915 datetime; the class string.Formatter; and the C API
3916 PyObject_Format().
3917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Fixed several potential crashes, all caused by specially crafted
3919 __del__ methods exploiting objects in temporarily inconsistent
3920 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003921
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003922- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923 prevent a possible crash: an Abstract Base Class would try to access
3924 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003925

Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Clear all free lists during a gc.collect() of the highest generation
3930 in order to allow pymalloc to free more arenas. Python may give back
3931 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003932
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933- Issue #2045: Fix an infinite recursion triggered when printing a
3934 subclass of collections.defaultdict, if its default_factory is set
3935 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003936
Christian Heimesf75dbef2008-02-08 00:11:31 +00003937- Fixed a minor memory leak in dictobject.c. The content of the free
3938 list was not freed on interpreter shutdown.
3939
Georg Brandl21e99f42010-03-07 15:23:59 +00003940- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3944 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003945 to compact the internal free lists of pre-allocted ints and floats.
3946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3948 calls. Python expected the return type int but the fork familie
3949 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003950

3961 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Patch #1473257: generator objects gain a gi_code attribute. This is
3964 the same object as the func_code attribute of the function that
3965 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Issue #1920: "while 0" statements were completely removed by the
3968 compiler, even in the presence of an "else" clause, which is
3969 supposed to be run when the condition is false. Now the compiler
3970 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003971
Guido van Rossumeead05f2008-01-24 18:21:02 +00003972- A few crashers fixed: weakref_in_del.py (issue #1377858);
3973 loosing_dict_ref.py (issue #1303614, test67.py);
3974 borrowed_ref_[34].py (not in tracker).
3975
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003976- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003977 suppressed while an extension is loaded by calling SetErrorMode in

3979
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003981 several extension methods and modules do not work without unicode
3982 support.
3983
Georg Brandl26543b12008-01-21 18:36:51 +00003984- Issue #1882: when compiling code from a string, encoding cookies in the

3986
Georg Brandl14404b62008-01-19 19:27:05 +00003987- Issue #1679: "0x" was taken as a valid integer literal.
3988
Georg Brandl6caad7d2008-01-26 14:19:22 +00003989- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003990 added.
3991
Christian Heimesc94e2b52008-01-14 04:13:37 +00003992- sys.float_info / PyFloat_GetInfo: The floating point information
3993 object was converted from a dict to a specialized structseq object.
3994
Georg Brandl3ee81df2008-05-17 18:14:43 +00003995- Patch #1816: Added sys.flags structseq. It exposes the status of
3996 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003997
Georg Brandl3ee81df2008-05-17 18:14:43 +00003998- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00004002- Patch #1700288: added a type attribute cache that caches method
4003 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandlaed6c662008-01-07 17:25:53 +00004008- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4009
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4011 envvar and sys.dont_write_bytecode attribute. All these can be set
4012 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004013
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014- Improve some exception messages when Windows fails to load an
4015 extension module. Now we get for example '%1 is not a valid Win32
4016 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004023- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024 and INF. float("nan"), float("inf") and float("-inf") now work on
4025 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Compiler now generates simpler and faster code for dictionary
4028 literals. The oparg for BUILD_MAP now indicates an estimated
4029 dictionary size. There is a new opcode, STORE_MAP, for adding
4030 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- Patch #1739468: Directories and zipfiles containing a __main__.py
4060 file can now be directly executed by passing their name to the
4061 interpreter. The directory/zipfile is automatically inserted as the
4062 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004064- Issue #1265: Fix a problem with sys.settrace, if the tracing
4065 function uses a generator expression when at the same time the
4066 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004067
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004068- sets and frozensets now have an isdisjoint() method.

4073
Georg Brandl21e99f42010-03-07 15:23:59 +00004074- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4076 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004077
Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- Issue #1686386: Tuple's tp_repr did not take into account the
4079 possibility of having a self-referential tuple, which is possible
4080 from C code. Nor did object's tp_str consider that a type's tp_str
4081 could do something that could lead to an inifinite recursion.
4082 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4083 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- Issue #1164: It was possible to trigger deadlock when using the
4086 'print' statement to write to a file since the GIL was not released
4087 as needed. Now PyObject_Print() does the right thing along with
4088 various tp_print implementations of the built-in types and those in
4089 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004097
Brett Cannon1e534b52007-09-07 04:18:30 +00004098- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099 PyObject_Call() never calling back out to Python code to trigger
4100 recursion depth updates/checks. Required the creation of a static
4101 RuntimeError instance in case normalizing an exception put the
4102 recursion check value past its limit. Fixes crashers
4103 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004104

Neal Norwitz0ac60192007-05-27 04:08:54 +00004118- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119 __*__ attributes. (Some already existed, e.g., __doc__ and
4120 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004121
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004122- Add -3 option to the interpreter to warn about features that are
4123 deprecated and will be changed/removed in Python 3.0.
4124
Georg Brandl2134e752007-05-21 20:34:16 +00004125- Patch #1686487: you can now pass any mapping after '**' in function
4126 calls.
4127
Collin Winter62903052007-05-18 23:11:24 +00004128- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129 "except E as target:". This is to provide forwards compatibility
4130 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004137- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004138 setting a plain string, ie don't expand to single letter identifiers.
4139
Raymond Hettinger13936692007-04-11 18:40:58 +00004140- Request #1191699: Slices can now be pickled.
4141
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004142- Request #1193128: str.translate() now allows a None argument for
4143 translations that only remove characters without re-mapping the
4144 remaining characters.
4145
Georg Brandl5cb76c12007-03-21 09:00:39 +00004146- Patch #1682205: a TypeError while unpacking an iterable is no longer
4147 masked by a generic one with the message "unpack non-sequence".
4148
Neal Norwitzaa754b72007-03-21 06:39:48 +00004149- Remove unused file Python/fmod.c.
4150
Guido van Rossum143b5642007-03-23 04:58:42 +00004151- Bug #1683368: The object.__init__() and object.__new__() methods are
4152 now stricter in rejecting excess arguments. The only time when
4153 either allows excess arguments is when it is not overridden and the
4154 other one is. For backwards compatibility, when both are
4155 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004156 warning later). Also, type.__init__() insists on the same signature
4157 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4160 object to complex using its __complex__() method before falling back
4161 to the __float__() method. Therefore, the functions in the cmath
4162 module now can operate on objects that define a __complex__()
4163 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Patch #1623563: allow __class__ assignment for classes with
4166 __slots__. The old and the new class are still required to have the
4167 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004168

4174 its type.

4180
Georg Brandl7b9c5552007-03-12 14:30:05 +00004181- Bug #1678647: write a newline after printing an exception in any
4182 case, even when converting the value to a string failed.
4183
Georg Brandl871f1bc2007-03-12 13:17:36 +00004184- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 its argument, if it exists. If not, it will work like before. This
4186 allows customizing the output of dir() in the presence of a
4187 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004188
Collin Winter276887b2007-03-12 16:11:39 +00004189- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Patch #1491866: change the complex() constructor to allow
4196 parthensized forms. This means complex(repr(x)) now works instead of
4197 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004198
Georg Brandlaa2321b2007-03-07 00:40:28 +00004199- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200 makes the filenames the warning module prints much more sensible
4201 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004202

Georg Brandl0fca97a2007-03-05 22:28:08 +00004214- Patch #1674228: when assigning a slice (old-style), check for the
4215 sq_ass_slice instead of the sq_slice slot.
4216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- When printing an unraisable error, don't print exceptions. before
4218 the name. This duplicates the behavior whening normally printing
4219 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004752 AttributeError instead of an IOError when the server's response
4753 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004754

Georg Brandl3ee81df2008-05-17 18:14:43 +00004759- Patch #1429539: pdb now correctly initializes the __main__ module
4760 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004761 correctly now.
4762

4769
Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Patch #1530482: add pydoc.render_doc() which returns the

4785
Georg Brandl92a6bae2007-03-13 17:43:32 +00004786- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787 are set for invalid interpolation sequences that would lead to
4788 errors on reading back those values.

4829

4831 returned string up to the first NUL character.

4842
Georg Brandl3ee81df2008-05-17 18:14:43 +00004843- unittest now verifies more of its assumptions. In particular,
4844 TestCase and TestSuite subclasses (not instances) are no longer
4845 accepted in TestSuite.addTest(). This should cause no
4846 incompatibility since it never made sense with ordinary subclasses
4847 -- the failure just occurred later, with a more cumbersome
4848 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005135 that the SMTP.starttls() caller no longer needs to call ehlo()

5219 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5220 silently miscode subclasses of those types. Now, it raises a
5221 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005236- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237 time so that opening a database previously created with the DB_DUP
5238 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5239 opens. Specifically: dictionary assignment to a DB object will
5240 replace all values for a given key when the database allows
5241 duplicate values. DB users should use DB.put(k, v) when they want
5242 to store duplicates; not DB[k] = v.

5249 characters with ASCII value less than 32. Also, it correctly quotes
5250 dots only if they occur on a single line, as opposed to the previous
5251 behavior of quoting dots if they are the second character of any
5252 line.

5598 of w# format code incorrectly truncated the length to an int, even
5599 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5600 incorrect results with huge strings.
