Ned Deily18fae3f2013-01-31 01:24:55 -08001222- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1223 In particular, fix extension module build failures when trying to use
1224 32-bit-only installer Pythons on systems with Xcode 4 (currently
1225 OS X 10.8, 10.7, and optionally 10.6).
1226 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1227 * Since Xcode 4 removes ppc support, extension module builds now
1228 check for ppc compiler support and by default remove ppc and
1229 ppc64 archs when they are not available.
1230 * Extension module builds now revert to using system installed
1231 headers and libs (/usr and /System/Library) if the SDK used
1232 to build the interpreter is not installed or has moved.
1233 * Try to avoid building extension modules with deprecated
1234 and problematic Apple llvm-gcc compiler. If original compiler
1235 is not available, use clang instead by default.

1590 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001666- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1667 Distutils-based packages with C extension modules may fail because
1668 Apple has removed gcc-4.2, the version used to build python.org
1669 64-bit/32-bit Pythons. If the user does not explicitly override
1670 the default C compiler by setting the CC environment variable,
1671 Distutils will now attempt to compile extension modules with clang
1672 if gcc-4.2 is required but not found. Also as a convenience, if
1673 the user does explicitly set CC, substitute its value as the default
1674 compiler in the Distutils LDSHARED configuration variable for OS X.
1675 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1676 SDK, neither of which are available in Xcode 4. This change does not
1677 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001927- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1928 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1929 interpreter process. This could cause failures in non-Distutils subprocesses
1930 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001931 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001932 deployment target only in the environment of each build subprocess. It is
1933 still possible to globally override the default by setting
1934 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1935 greater or equal to the default value, the value with which the interpreter
1936 was built.

R David Murrayf1138bb2011-06-17 22:23:04 -04001944- Issue #11700: mailbox proxy object close methods can now be called multiple
1945 times without error, and _ProxyFile now closes the wrapped file.
1946
Victor Stinnerc74a6ba2011-06-17 14:06:27 +02001947- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
1948 connection if its getresponse() method fails with a socket error. Patch
1949 written by Ezio Melotti.
1950
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -05001951- Issue #9284: Allow inspect.findsource() to find the source of doctest

1963
Barry Warsawc5643282011-07-19 17:06:30 -04001964- sys.setcheckinterval() now updates the current ticker count as well as
1965 updating the check interval, so if the user decreases the check interval,
1966 the ticker doesn't have to wind down to zero from the old starting point
1967 before the new interval takes effect. And if the user increases the
1968 interval, it makes sure the new limit takes effect right away rather have an
1969 early task switch before recognizing the new interval.

2920 received. Now sendall() properly calls signal handlers if necessary,
2921 and retries sending if these returned successfully, including on sockets

2939 by Andrew Bennetts.

2948
Raymond Hettinger20397532010-09-12 02:11:45 +00002949- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2950 This prevents user-created self-referencing ordered dictionaries from
2951 becoming permanently uncollectable GC garbage. The downside is that
2952 removing __del__ means that the internal doubly-linked list has to wait for
2953 GC collection rather than freeing memory immediately when the refcnt drops
2954 to zero.
2955

2983 falling into recursion.
2984
R. David Murray7c4bf552010-08-25 01:45:57 +00002985- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2986 character years even if the message contains RFC822 two character years.
2987
Daniel Stutzbach91287322010-08-24 21:09:30 +00002988- Issue #8750: Fixed MutableSet's methods to correctly handle

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003020- Issue #9550: a BufferedReader could issue an additional read when the
3021 original read request had been satisfied, which could block indefinitely
3022 when the underlying raw IO channel was e.g. a socket. Report and original
3023 patch by Jason V. Miller.

3208 compared to other unix systems. In particular, os.getgroups() does
3209 not reflect any changes made using os.setgroups() but basicly always
3210 returns the same information as the id command.
3211
3212 os.getgroups() can now return more than 16 groups on MacOSX.

R. David Murray1a14d3d2010-04-12 16:35:19 +00003726- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00003727 filename and date, conforming to the 'standards' they were originally designed
3728 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003774 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3775 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3776 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3797-----------------
3798
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003799- Issue #7301: Add environment variable $PYTHONWARNINGS.
3800
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003801- Issue #8329: Don't return the same lists from select.select when no fds are
3802 changed.
3803
Georg Brandlfee0f442010-05-22 21:26:21 +00003804- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003805 on 64-bit machines. The shift count for either left or right shift is
3806 permitted to be up to sys.maxsize.
3807
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003808- Ensure that tokenization of identifiers is not affected by locale.
3809
Georg Brandlfee0f442010-05-22 21:26:21 +00003810- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003811
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003812- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3813
Georg Brandlfee0f442010-05-22 21:26:21 +00003814- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3815 with a non-empty format string. This is an effort to future-proof user
3816 code. If a derived class does not currently implement __format__ but later
3817 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003818 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003819 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003820
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003821- Issue #8268: Old-style classes (not just instances) now support weak

3833
Victor Stinner66644262010-03-10 22:30:19 +00003834- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003835 (SIGINT). If an error occurs while importing the site module, the error is
3836 printed and Python exits. Initialize the GIL before importing the site

3851
Georg Brandlfee0f442010-05-22 21:26:21 +00003852- Issue #8257: The Decimal construct now accepts a float instance directly,
3853 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003854
3855 >>> Decimal(1.1)
3856 Decimal('1.100000000000000088817841970012523233890533447265625')
3857
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003858- collections.Counter() now supports a subtract() method.
3859
Georg Brandlfee0f442010-05-22 21:26:21 +00003860- The functools module now has a total_ordering() class decorator to simplify
3861 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003862
Georg Brandlfee0f442010-05-22 21:26:21 +00003863- The functools module also adds cmp_to_key() as a tool to transition old-style
3864 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003865
Georg Brandlfee0f442010-05-22 21:26:21 +00003866- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3867 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003868
Georg Brandlfee0f442010-05-22 21:26:21 +00003869- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3870 InvalidOperation instead of returning False. (Comparisons involving a quiet
3871 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3872 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003873
Georg Brandlfee0f442010-05-22 21:26:21 +00003874- Issue #2531: Comparison operations between floats and Decimal instances now
3875 return a result based on the numeric values of the operands; previously they
3876 returned an arbitrary result based on the relative ordering of id(float) and
3877 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003878
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003879- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003880 argument `-` which tells it to read files to compile from stdin. Each line is
3881 read on demand and the named file is compiled immediately. (Original patch by
3882 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003887- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3888 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003889 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003890
Georg Brandlfee0f442010-05-22 21:26:21 +00003891- Comparisons using one of <, <=, >, >= between a complex instance and a
3892 Fractions instance now raise TypeError instead of returning True/False. This
3893 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3894 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003895

4003 the set of integer codes for which it was used differed between native packing
4004 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004312 file position when calling `truncate()`. It would previously change the file
4313 position to the given argument, which goes against the tradition of

4317 class used to represent files stored inside an archive. The new
4318 implementation is significantly faster and can be wrapped in a
4319 ``io.BufferedReader`` object for more speedups. It also solves an issue
4320 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4333 encoded string for them. This ensures that the upload and register commands
4334 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004605- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4606 decimal string that's guaranteed to round back to x under correct rounding
4607 (with round-half-to-even rounding mode). Previously it gave a string based on
4608 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4609 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4610 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004611
Georg Brandlba83f822010-03-14 09:50:54 +00004612- Issue #7117: On almost all platforms: float-to-string and string-to-float
4613 conversions within Python are now correctly rounded. Places these conversions
4614 occur include: str for floats and complex numbers; the float and complex
4615 constructors; old-style and new-style numeric formatting; serialization and
4616 deserialization of floats and complex numbers using marshal, pickle and json;
4617 parsing of float and imaginary literals in Python code; Decimal-to-float
4618 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004619
Georg Brandlba83f822010-03-14 09:50:54 +00004620 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4621 providing correctly-rounded strtod and dtoa C functions. This code is
4622 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4623 the C compiler. There may be a small number of platforms on which correct
4624 operation of this code cannot be guaranteed, so the code is not used: notably,
4625 this applies to platforms where the C double format is not IEEE 754 binary64,
4626 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4627 and Python's configure script is unable to determine how to change the FPU
4628 precision. On these platforms conversions use the platform strtod and dtoa,
4629 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004631- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4632 uses the correctly-rounded string <-> float conversions described above (when
4633 available), and so produces correctly rounded results that will display nicely
4634 under the float repr. There are two related small changes: (1) round now
4635 accepts any class with an ``__index__()`` method for its second argument (but
4636 no longer accepts floats for the second argument), and (2) an excessively
4637 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4638 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004785- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4786 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4787 but with at least one decimal point and with a default precision
4788 of 12. Previously, the behavior the same but with a default precision of 6.
4789 This more closely matches ``str()``, and reduces surprises when adding
4790 alignment flags to the empty presentation type. This also affects the new
4791 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004931- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4932 existing .py counterpart, override the co_filename attributes of all code

4988
Georg Brandlba83f822010-03-14 09:50:54 +00004989- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4990 file objects with closefd=False. The file descriptor is still kept open but
4991 the file object behaves like a closed file. The ``FileIO`` object also got a
4992 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005012- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005015- On windows, ``os.chdir()`` given unicode was not working if
5016 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5017 this code path is really executed because I cannot move to such directory on
5018 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005020- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5021 element is temporarily replaced with an equivalent frozenset. But the
5022 eventual KeyError would always report the empty ``frozenset()`` as the missing
5023 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005043- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5044 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5045 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5046 of using the replace error handler in PyUnicode_DecodeUTF8().
5047
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005048- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005051- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5053 gives improved memory leak detection when running under Valgrind, while taking
5054 advantage of pymalloc at other times.

6423
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006424- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6425 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6426 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6427 ``printf`` function, whereas PyString_FromFormat has an independent
6428 implementation and uses "%zd" on all platforms for size_t values.
6429 This makes a difference on win64, where ``printf`` needs "%Id" to display
6430 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006432- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6436 object; previously an int would be returned for small values. the __long__
6437 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006447 was correctly parsed but parsing of subsequent arguments failed.
6448
Vinay Sajip35e3b032008-09-01 14:33:59 +00006449- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006450 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6451 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6453 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6454 type object.

6551
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006552- Issue #2975: When compiling several extension modules with Visual Studio 2008
6553 from the same python interpreter, some environment variables would grow
6554 without limit.
6555
Benjamin Peterson37346b22008-08-23 20:27:43 +00006556- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

6572 wrapper for warnings.catch_warnings() that makes it easier to check
6573 that expected warning messages are being reported.
6574

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006593What's New in Python 2.6 beta 3?
6594================================
6595
Barry Warsaw07a4a382008-08-21 01:15:08 +00006596*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006597
6598Core and Builtins
6599-----------------
6600
Guido van Rossumf8402962008-08-20 15:01:50 +00006601- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6602 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6603 extensions do not automatically benefit from the class attribute
6604 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6605 to their tp_flags field if they care. This is a backwards
6606 compatibility feature; in 3.0, all types will use the cache by
6607 default.
6608
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006609- Keyword arguments can now follow starred arguments. (``f(a, *args,
6610 keyword=23)`` is now valid syntax.)
6611
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006612- ctypes function pointers that are COM methods have a boolean True
6613 value again.
6614
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006615- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6616 by denying s# to parse objects that have a releasebuffer procedure,
6617 and introducing s*.
6618
Georg Brandl1e13ea92008-08-11 09:07:59 +00006619- Issue #3537: Fix an assertion failure when an empty but presized dict
6620 object was stored in the freelist.
6621
Mark Dickinsonb6467572008-08-04 21:30:09 +00006622- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6623 ValueError consistently across platforms.
6624
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006625- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6626 (64bit Unix, for example), unichr() would truncate its argument and return
6627 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6628
Neal Norwitze7d8be82008-07-31 17:17:14 +00006629- Apply security patches from Apple.
6630
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006631- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6632 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6633
Antoine Pitrou92f82162008-07-25 22:22:08 +00006634- Issue #1819: function calls with several named parameters are now on
6635 average 35% faster (as measured by pybench).
6636
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006637- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6638 the python debugger steps into a class statement: the free variables (local
6639 variables defined in an outer scope) would be deleted from the outer scope.
6640
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006641- Issue #2620: Overflow checking when allocating or reallocating memory
6642 was not always being done properly in some python types and extension
6643 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6644 all been updated to perform better checks and places in the code that
6645 would previously leak memory on the error path when such an allocation
6646 failed have been fixed.
6647
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006648Library
6649-------
6650
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006651- Issue #3612: Added some missing basic types in ctypes.wintypes.
6652
Benjamin Petersone977ad42008-08-20 01:42:01 +00006653- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6654 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6655
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006656- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6657 version reported by these tools does not necessarily follow the python
6658 version numbering scheme, so the module is less strict when parsing it.
6659
Nick Coghlanf70385a2008-08-18 12:42:46 +00006660- Issue #2235: Added Py3k warnings for types which will become unhashable
6661 under the stricter __hash__ inheritance rules in 3.0. Several types
6662 which did not meet the rules for hash invariants and were already
6663 unhashable in 3.0 have now been explicitly flagged as unhashable in
6664 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6665 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6666
Brett Cannon88f801d2008-08-18 00:46:22 +00006667- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6668 imported into the module but exposed as part of the module's API.
6669
Brett Cannon7b96f072008-08-18 00:41:11 +00006670- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6671
Brett Cannon46225e72008-08-18 00:36:52 +00006672- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6673
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006674- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6675
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006676- Issue #3575: Incremental decoder's decode function now takes bytearray
6677 by using 's*' instead of 't#'.
6678
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006679- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006680 fails unicode conversion on 2nd parameter. (windows only)
6681
Georg Brandl222e2082010-08-01 22:27:39 +00006682- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006683 in a redirect.
6684
Brett Cannonabe423e2008-08-16 21:47:07 +00006685- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006686 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006687
Facundo Batistaeb90b782008-08-16 14:44:07 +00006688- Issue #2776: fixed small issue when handling an URL with double slash
6689 after a 302 response in the case of not going through a proxy.
6690
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006691- Issue #2676: in the email package, content-type parsing was hanging on
6692 pathological input because of quadratic or exponential behaviour of a
6693 regular expression.
6694
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006695- Issue #3476: binary buffered reading through the new "io" library is now
6696 thread-safe.
6697
Brett Cannonbf3157b2008-08-14 05:00:03 +00006698- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6699 since mimetools itself is deprecated. Because modules are cached, all
6700 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6701
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006702- Issue #3134: shutil referenced undefined WindowsError symbol.
6703
Robert Schuppenies14646332008-08-10 11:01:53 +00006704- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6705 menu entries were not deleted.
6706
Brett Cannon83e81842008-08-09 23:30:55 +00006707- Copied the implementation of reduce() to _functools.reduce() to have a
6708 version that did not raise a DeprecationWarning under -3.
6709
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006710- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6711 a MemoryError rather than silently stop the iteration.
6712
Guido van Rossum59ce9012008-08-09 14:55:34 +00006713- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6714 to _sre.compile() will now be rejected. This should not affect anybody
6715 since the re.compile() function never generates invalid re-bytecode.
6716
Skip Montanaroa032bf42008-08-08 22:52:51 +00006717- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6718 upon first access it can be automatically initialized from the csv file if
6719 it wasn't initialized during instantiation.
6720
Brett Cannon3aa2a492008-08-06 22:28:09 +00006721- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6722 the reload() built-in has been removed.
6723
Brett Cannon7e30b672008-08-04 21:52:25 +00006724- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006725 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6733 raised an AttributeError.
6734
Benjamin Peterson01a24322008-07-28 23:35:27 +00006735- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006736 asking for a specific length. This problem only affected files opened
6737 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006738
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006739- Issue #3449: Update decimal module to use most recent specification
6740 (v. 1.68) and tests (v. 2.58) from IBM.
6741
Georg Brandl222e2082010-08-01 22:27:39 +00006742- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6761
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006762- Issue #3394: zipfile.writestr sets external attributes when passed a
6763 file name rather than a ZipInfo instance, so files are extracted with
6764 mode 0600 rather than 000 under Unix.
6765
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006766- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6767 argument in python 2.5, this broke code that subclassed Popen to include its
6768 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006778- Issue #2235: the C API function PyObject_HashNotImplemented and its
6779 interaction with the tp_hash slot (added in 2.6b2) are now documented
6780
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006781- Issue #643841: The language reference now provides more detailed
6782 coverage of the lookup process for special methods. The disclaimers
6783 regarding lack of coverage of new-style classes have also been
6784 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006792Core and Builtins
6793-----------------
6794
Georg Brandl3e483f62008-07-16 22:57:41 +00006795- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6796 its methods now allow for items objects that can be converted to
6797 an integer using operator.index().
6798
Mark Dickinson64b7e502008-07-16 09:40:03 +00006799- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6800 produced a ValueError instead of giving the correct float.
6801
Eric Smitha5fa5a22008-07-16 00:11:49 +00006802- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6803 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6804
Mark Dickinson7103aa42008-07-15 19:08:33 +00006805- Issue #3008: the float type has a new instance method 'float.hex'
6806 and a new class method 'float.fromhex' to convert floating-point
6807 numbers to and from hexadecimal strings, respectively.
6808
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006809- Issue #2235: __hash__ is once again inherited by default. To allow
6810 collections.Hashable to remain meaningful in the presence of the
6811 default hash implementation (object.__hash__), it is now possible
6812 to explicit block inheritance of hash by setting __hash__=None at
6813 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6814 level.
6815
Nick Coghlanb028f502008-07-13 14:52:36 +00006816- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6817 the parent module cannot be found while performing an absolute import.
6818 This means that an incorrectly defined __package__ attribute will
6819 now only prevent relative imports in that module rather than causing
6820 all imports from that module to fail.
6821
Nick Coghlan14ff9942008-07-08 14:21:42 +00006822- Issue #2517: Allow unicode messages in Exceptions again by correctly

6835 arguments are now treated identically, making the behaviour easier

6838 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6839 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00007293 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007294
7295 This is controlled by the configure argument ``--with-universal-archs``:
7296

7298
7299 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7300
7301 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7302

7342 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007355- Issue #1631171: Re-implement the 'warnings' module in C (the
7356 original Python code has been kept as backup). This will allow for
7357 using the 'warning's machinery in such places as the parser where
7358 use of pure Python code is not possible. Both the ``showarning()``
7359 and ``formatwarning()`` gain an optional 'line' argument which is
7360 not called by default for backwards-compatibility reasons. Setting
7361 ``warnings.showwarning()`` to an implementation that lacks support
7362 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007425- Issue #2550: The approach used by client/server code for obtaining
7426 ports to listen on in network-oriented tests has been refined in an
7427 effort to facilitate running multiple instances of the entire
7428 regression test suite in parallel without issue.
7429 test_support.bind_port() has been fixed such that it will always
7430 return a unique port -- which wasn't always the case with the
7431 previous implementation, especially if socket options had been set
7432 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7433 new implementation of bind_port() will actually raise an exception
7434 if it is passed an AF_INET/SOCK_STREAM socket with either the
7435 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7436 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7437 the socket it's been passed. This currently only applies to
7438 Windows. This option prevents any other sockets from binding to the
7439 host/port we've bound to, thus removing the possibility of the
7440 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7441 when a second SOCK_STREAM socket binds and accepts to a host/port
7442 that's already been bound by another socket. The optional preferred
7443 port parameter to bind_port() has been removed. Under no
7444 circumstances should tests be hard coding ports!
7445
7446 test_support.find_unused_port() has also been introduced, which will
7447 pass a temporary socket object to bind_port() in order to obtain an
7448 unused port. The temporary socket object is then closed and
7449 deleted, and the port is returned. This method should only be used
7450 for obtaining an unused port in order to pass to an external program
7451 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7452 a parameter to a server-oriented class that doesn't give you direct
7453 access to the underlying socket used.
7454
7455 Finally, test_support.HOST has been introduced, which should be used
7456 for the host argument of any relevant socket calls (i.e. bind and
7457 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007458
7459 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007460 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007461 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7462 test_asynchat and test_socket_ssl.
7463
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464 It is now possible for multiple instances of the regression test
7465 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00007648- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00007649 optional: it defaults to the traceback of the exception that is
7650 currently being handled (is mandatory to be in the middle of an
7651 exception, otherwise it raises ValueError).

7667 from 't' to '?'.
7668
Thomas Heller78b8f442008-03-05 14:53:39 +00007669- The bundled libffi copy is now in sync with the recently released
7670 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007671 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
7672 files are used. On all linux systems the --with-system-ffi
7673 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00007734- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007735 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00007737- Issue #2067: file.__exit__() now calls subclasses' close() method.
7738
7739- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007740
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007741- Issue #1881: An internal parser limit has been increased. Also see

Facundo Batistafc2d0102008-02-23 12:01:13 +00007743
Eric Smitha73fbe72008-02-23 03:09:44 +00007744- Added the future_builtins module, which contains hex() and oct().
7745 These are the PEP 3127 version of these functions, designed to be
7746 compatible with the hex() and oct() builtins from Python 3.0. They
7747 differ slightly in their output formats from the existing, unchanged
7748 Python 2.6 builtins. The expected usage of the future_builtins
7749 module is:
7750 from future_builtins import hex, oct
7751
Eric Smith7ef40bf2008-02-20 23:34:22 +00007752- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7753 exponents for exponents with absolute value < 100. Follows C99
7754 standard. This is a change on Windows, which would use 3 digits.
7755 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7756 so that any alterations it does to the resulting string will be
7757 available in stringlib/formatter.h (for float.__format__).
7758
Eric Smith5a3c1352008-02-19 13:21:56 +00007759- Implemented PEP 3101, Advanced String Formatting. This adds a new
7760 builtin format(); a format() method for str and unicode; a
7761 __format__() method to object, str, unicode, int, long, float, and
7762 datetime; the class string.Formatter; and the C API
7763 PyObject_Format().
7764
Georg Brandl3ee81df2008-05-17 18:14:43 +00007765- Fixed several potential crashes, all caused by specially crafted
7766 __del__ methods exploiting objects in temporarily inconsistent
7767 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007768
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007769- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007770 prevent a possible crash: an Abstract Base Class would try to access
7771 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773- Fixed repr() and str() of complex numbers with infinity or nan as
7774 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007776- Clear all free lists during a gc.collect() of the highest generation
7777 in order to allow pymalloc to free more arenas. Python may give back
7778 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007779
Georg Brandl3ee81df2008-05-17 18:14:43 +00007780- Issue #2045: Fix an infinite recursion triggered when printing a
7781 subclass of collections.defaultdict, if its default_factory is set
7782 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007783
Christian Heimesf75dbef2008-02-08 00:11:31 +00007784- Fixed a minor memory leak in dictobject.c. The content of the free
7785 list was not freed on interpreter shutdown.
7786
Georg Brandl21e99f42010-03-07 15:23:59 +00007787- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007788 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007789
Georg Brandl3ee81df2008-05-17 18:14:43 +00007790- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7791 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007792 to compact the internal free lists of pre-allocted ints and floats.
7793
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7795 calls. Python expected the return type int but the fork familie
7796 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007797
Georg Brandl3ee81df2008-05-17 18:14:43 +00007798- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7799 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007800
Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7802 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007807- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7808 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007809
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Patch #1473257: generator objects gain a gi_code attribute. This is
7811 the same object as the func_code attribute of the function that
7812 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007813
Georg Brandl3ee81df2008-05-17 18:14:43 +00007814- Issue #1920: "while 0" statements were completely removed by the
7815 compiler, even in the presence of an "else" clause, which is
7816 supposed to be run when the condition is false. Now the compiler
7817 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007818
Guido van Rossumeead05f2008-01-24 18:21:02 +00007819- A few crashers fixed: weakref_in_del.py (issue #1377858);
7820 loosing_dict_ref.py (issue #1303614, test67.py);
7821 borrowed_ref_[34].py (not in tracker).
7822
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007823- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007824 suppressed while an extension is loaded by calling SetErrorMode in
7825 dynload_win.c. The error is still reported properly.
7826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007828 several extension methods and modules do not work without unicode
7829 support.
7830
Georg Brandl26543b12008-01-21 18:36:51 +00007831- Issue #1882: when compiling code from a string, encoding cookies in the
7832 second line of code were not always recognized correctly.
7833
Georg Brandl14404b62008-01-19 19:27:05 +00007834- Issue #1679: "0x" was taken as a valid integer literal.
7835
Georg Brandl6caad7d2008-01-26 14:19:22 +00007836- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007837 added.
7838
Christian Heimesc94e2b52008-01-14 04:13:37 +00007839- sys.float_info / PyFloat_GetInfo: The floating point information
7840 object was converted from a dict to a specialized structseq object.
7841
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842- Patch #1816: Added sys.flags structseq. It exposes the status of
7843 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007844
Georg Brandl3ee81df2008-05-17 18:14:43 +00007845- Objects/structseq.c: Implemented new structseq representation. The
7846 patch makes structseqs (e.g. the return value of os.stat) more
7847 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007848
Georg Brandl3ee81df2008-05-17 18:14:43 +00007849- Patch #1700288: added a type attribute cache that caches method

7858 envvar and sys.dont_write_bytecode attribute. All these can be set
7859 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007860
Georg Brandl3ee81df2008-05-17 18:14:43 +00007861- Improve some exception messages when Windows fails to load an
7862 extension module. Now we get for example '%1 is not a valid Win32
7863 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007871 and INF. float("nan"), float("inf") and float("-inf") now work on
7872 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007873
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874- Compiler now generates simpler and faster code for dictionary
7875 literals. The oparg for BUILD_MAP now indicates an estimated
7876 dictionary size. There is a new opcode, STORE_MAP, for adding
7877 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007906- Patch #1739468: Directories and zipfiles containing a __main__.py
7907 file can now be directly executed by passing their name to the
7908 interpreter. The directory/zipfile is automatically inserted as the
7909 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007910
Georg Brandl3ee81df2008-05-17 18:14:43 +00007911- Issue #1265: Fix a problem with sys.settrace, if the tracing
7912 function uses a generator expression when at the same time the
7913 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007914
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007915- sets and frozensets now have an isdisjoint() method.
7916

7920
Georg Brandl21e99f42010-03-07 15:23:59 +00007921- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007922 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7923 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Issue #1686386: Tuple's tp_repr did not take into account the
7926 possibility of having a self-referential tuple, which is possible
7927 from C code. Nor did object's tp_str consider that a type's tp_str
7928 could do something that could lead to an inifinite recursion.
7929 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7930 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007931
Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- Issue #1164: It was possible to trigger deadlock when using the
7933 'print' statement to write to a file since the GIL was not released
7934 as needed. Now PyObject_Print() does the right thing along with
7935 various tp_print implementations of the built-in types and those in
7936 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007937
Georg Brandl3ee81df2008-05-17 18:14:43 +00007938- Issue #1147: Exceptions were directly allowing string exceptions in
7939 their throw() method even though string exceptions no longer
7940 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007941
Georg Brandl3ee81df2008-05-17 18:14:43 +00007942- Issue #1096: Prevent a segfault from getting the repr of a very
7943 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007944
Brett Cannon1e534b52007-09-07 04:18:30 +00007945- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007946 PyObject_Call() never calling back out to Python code to trigger
7947 recursion depth updates/checks. Required the creation of a static
7948 RuntimeError instance in case normalizing an exception put the
7949 recursion check value past its limit. Fixes crashers
7950 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007951
Georg Brandl3ee81df2008-05-17 18:14:43 +00007952- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007965- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966 __*__ attributes. (Some already existed, e.g., __doc__ and
7967 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007968
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007969- Add -3 option to the interpreter to warn about features that are
7970 deprecated and will be changed/removed in Python 3.0.
7971
Georg Brandl2134e752007-05-21 20:34:16 +00007972- Patch #1686487: you can now pass any mapping after '**' in function
7973 calls.
7974
Collin Winter62903052007-05-18 23:11:24 +00007975- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007976 "except E as target:". This is to provide forwards compatibility
7977 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007978
Brett Cannon229cee22007-05-05 01:34:02 +00007979- Deprecate BaseException.message as per PEP 352.
7980
Georg Brandl3ee81df2008-05-17 18:14:43 +00007981- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007982 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007983
Vinay Sajip8549ce32007-05-06 17:53:37 +00007984- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007985 setting a plain string, ie don't expand to single letter identifiers.
7986
Raymond Hettinger13936692007-04-11 18:40:58 +00007987- Request #1191699: Slices can now be pickled.
7988
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007989- Request #1193128: str.translate() now allows a None argument for
7990 translations that only remove characters without re-mapping the
7991 remaining characters.
7992
Georg Brandl5cb76c12007-03-21 09:00:39 +00007993- Patch #1682205: a TypeError while unpacking an iterable is no longer
7994 masked by a generic one with the message "unpack non-sequence".
7995
Neal Norwitzaa754b72007-03-21 06:39:48 +00007996- Remove unused file Python/fmod.c.
7997
Guido van Rossum143b5642007-03-23 04:58:42 +00007998- Bug #1683368: The object.__init__() and object.__new__() methods are
7999 now stricter in rejecting excess arguments. The only time when
8000 either allows excess arguments is when it is not overridden and the
8001 other one is. For backwards compatibility, when both are
8002 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008003 warning later). Also, type.__init__() insists on the same signature
8004 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8007 object to complex using its __complex__() method before falling back
8008 to the __float__() method. Therefore, the functions in the cmath
8009 module now can operate on objects that define a __complex__()
8010 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008011
Georg Brandl3ee81df2008-05-17 18:14:43 +00008012- Patch #1623563: allow __class__ assignment for classes with
8013 __slots__. The old and the new class are still required to have the
8014 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008015
Georg Brandl3ee81df2008-05-17 18:14:43 +00008016- Patch #1642547: Fix an error/crash when encountering syntax errors

8020 ``object.__reduce_ex__()`` is called with an object that is faking
8021 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008022
Georg Brandl3ee81df2008-05-17 18:14:43 +00008023- Patch #1680015: Don't modify __slots__ tuple if it contains an

8027
Georg Brandl7b9c5552007-03-12 14:30:05 +00008028- Bug #1678647: write a newline after printing an exception in any
8029 case, even when converting the value to a string failed.
8030
Georg Brandl871f1bc2007-03-12 13:17:36 +00008031- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008032 its argument, if it exists. If not, it will work like before. This
8033 allows customizing the output of dir() in the presence of a
8034 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008035
Collin Winter276887b2007-03-12 16:11:39 +00008036- Patch #922167: Python no longer segfaults when faced with infinitely
8037 self-recursive reload() calls (as reported by bug #742342).
8038
Georg Brandl3ee81df2008-05-17 18:14:43 +00008039- Patch #1675981: remove unreachable code from ``type.__new__()``
8040 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008042- Patch #1491866: change the complex() constructor to allow
8043 parthensized forms. This means complex(repr(x)) now works instead of
8044 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008045
Georg Brandlaa2321b2007-03-07 00:40:28 +00008046- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008047 makes the filenames the warning module prints much more sensible
8048 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008049

8051 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008052 variable is given, but break into the interactive interpreter just
8053 like on other exceptions or normal program exit.

8059 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008060
Georg Brandl0fca97a2007-03-05 22:28:08 +00008061- Patch #1674228: when assigning a slice (old-style), check for the
8062 sq_ass_slice instead of the sq_slice slot.
8063
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064- When printing an unraisable error, don't print exceptions. before
8065 the name. This duplicates the behavior whening normally printing
8066 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00008149- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008208- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00008617- Patch #1530482: add pydoc.render_doc() which returns the

8632
Georg Brandl92a6bae2007-03-13 17:43:32 +00008633- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008634 are set for invalid interpolation sequences that would lead to

8691 TestCase and TestSuite subclasses (not instances) are no longer
8692 accepted in TestSuite.addTest(). This should cause no

8694 -- the failure just occurred later, with a more cumbersome
8695 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008970- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8971 with RFC 3207 and forgets any knowledge obtained from the server not
8972 obtained from the TLS negotiation itself. Patch contributed by Bill
8973 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008974
Georg Brandl3ee81df2008-05-17 18:14:43 +00008975- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008976 that the SMTP.starttls() caller no longer needs to call ehlo()
8977 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008978 does not claim to support starttls. Adds the
8979 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8980 Fenner.

9060 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9061 silently miscode subclasses of those types. Now, it raises a
9062 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009063

Georg Brandl3ee81df2008-05-17 18:14:43 +00009078 time so that opening a database previously created with the DB_DUP
9079 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9080 opens. Specifically: dictionary assignment to a DB object will
9081 replace all values for a given key when the database allows
9082 duplicate values. DB users should use DB.put(k, v) when they want
9083 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009084

9090 characters with ASCII value less than 32. Also, it correctly quotes
9091 dots only if they occur on a single line, as opposed to the previous
9092 behavior of quoting dots if they are the second character of any
9093 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009094
Georg Brandla47337f2007-03-13 12:34:25 +00009095- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009371- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009372 periodic threadstate and signal checking in tight loops. By
9373 default, this option is turned-off. It should only be enabled in
9374 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009375

9425-----
9426
Georg Brandl3ee81df2008-05-17 18:14:43 +00009427- Unified naming convention for free lists and their limits. All free
9428 lists in Object/ are named ``free_list``, the counter ``numfree``
9429 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9430 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009431
Georg Brandl3ee81df2008-05-17 18:14:43 +00009432- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9433 to ``PyTuple_SetItem``, it can be used to populate a brand new
9434 frozenset; but it does not steal a reference to the added item.

9443
9444- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9445 ``PyFloat_GetInfo()`` to the float API.
9446
Georg Brandl3ee81df2008-05-17 18:14:43 +00009447- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9448 of w# format code incorrectly truncated the length to an int, even
9449 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9450 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009451
Georg Brandl3ee81df2008-05-17 18:14:43 +00009452- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9470- Fix some leftovers from the conversion from int to Py_ssize_t
9471 (relevant to strings and sequences of more than 2**31 items).
9472
9473- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9474 outside of pystate.c and should not be necessary.
9475
Georg Brandl3ee81df2008-05-17 18:14:43 +00009476- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9477 absolute imports. In earlier versions they might have used relative
9478 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009479
Georg Brandl3ee81df2008-05-17 18:14:43 +00009480- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9481 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009482
Georg Brandl3ee81df2008-05-17 18:14:43 +00009483- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009508- Removed the macfs module. It had been deprecated since Python 2.5.
9509 This lead to the deprecation of macostools.touched() as it relied
