1607 32-bit-only installer Pythons on systems with Xcode 4 (currently
1608 OS X 10.8, 10.7, and optionally 10.6).
1609 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1610 * Since Xcode 4 removes ppc support, extension module builds now
1611 check for ppc compiler support and by default remove ppc and
1612 ppc64 archs when they are not available.
1613 * Extension module builds now revert to using system installed
1614 headers and libs (/usr and /System/Library) if the SDK used
1615 to build the interpreter is not installed or has moved.
1616 * Try to avoid building extension modules with deprecated
1617 and problematic Apple llvm-gcc compiler. If original compiler
1618 is not available, use clang instead by default.

2041
Florent Xiclunac2279652012-02-12 14:49:03 +01002042- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002043 has left two versions of customize_compiler, the original in
2044 distutils.sysconfig and another copy in distutils.ccompiler, with some
2045 parts of distutils calling one and others using the other.
2046 Complete the revert back to only having one in distutils.sysconfig as
2047 is the case in 3.x.
2048
Ned Deily0d0ea482012-02-10 12:59:06 +01002049- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2050 Distutils-based packages with C extension modules may fail because
2051 Apple has removed gcc-4.2, the version used to build python.org
2052 64-bit/32-bit Pythons. If the user does not explicitly override
2053 the default C compiler by setting the CC environment variable,
2054 Distutils will now attempt to compile extension modules with clang
2055 if gcc-4.2 is required but not found. Also as a convenience, if
2056 the user does explicitly set CC, substitute its value as the default
2057 compiler in the Distutils LDSHARED configuration variable for OS X.
2058 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2059 SDK, neither of which are available in Xcode 4. This change does not
2060 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002310- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2311 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2312 interpreter process. This could cause failures in non-Distutils subprocesses
2313 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002314 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002315 deployment target only in the environment of each build subprocess. It is
2316 still possible to globally override the default by setting
2317 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2318 greater or equal to the default value, the value with which the interpreter
2319 was built.

2349 the ticker doesn't have to wind down to zero from the old starting point
2350 before the new interval takes effect. And if the user increases the
2351 interval, it makes sure the new limit takes effect right away rather have an
2352 early task switch before recognizing the new interval.

3333 This prevents user-created self-referencing ordered dictionaries from
3334 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003795- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3796 start byte and the continuation byte(s) are now considered invalid, instead
3797 of the number of bytes specified by the start byte.
3798 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3799 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3800 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3801 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003803- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003804 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3805 arises from the "Overriding __eq__ blocks inheritance ..." warning
3806 when turned into an exception: in this case the exception simply
3807 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003808
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003809- Issue #8748: Fix two issues with comparisons between complex and integer
3810 objects. (1) The comparison could incorrectly return True in some cases
3811 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3812 (2) The comparison raised an OverflowError for large integers, leading
3813 to unpredictable exceptions when combining integers and complex objects
3814 in sets or dicts.
3815
Mark Dickinson81336372010-05-30 12:12:25 +00003816- Issue #5211: Implicit coercion for the complex type is now completely
3817 removed. (Coercion for arithmetic operations was already removed in 2.7
3818 alpha 4, but coercion for rich comparisons was accidentally left in.)
3819
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003820- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

3822
Georg Brandlfee0f442010-05-22 21:26:21 +00003823- Issue #7902: When using explicit relative import syntax, don't try implicit

4182
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004183- Issue #8329: Don't return the same lists from select.select when no fds are
4184 changed.
4185
Georg Brandlfee0f442010-05-22 21:26:21 +00004186- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004187 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00004196- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4197 with a non-empty format string. This is an effort to future-proof user
4198 code. If a derived class does not currently implement __format__ but later
4199 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004200 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004201 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004251- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4252 InvalidOperation instead of returning False. (Comparisons involving a quiet
4253 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlfee0f442010-05-22 21:26:21 +00004256- Issue #2531: Comparison operations between floats and Decimal instances now
4257 return a result based on the numeric values of the operands; previously they
4258 returned an arbitrary result based on the relative ordering of id(float) and
4259 id(Decimal).

Georg Brandlba83f822010-03-14 09:50:54 +00004595- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004596 is run with the -OO flag. Tests requiring docstrings are skipped.
4597
Georg Brandlba83f822010-03-14 09:50:54 +00004598- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4599 now also used by regrtest to run all the tests in a temporary directory. The
4600 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4601 Xicluna who helped with the patch.

4618 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004619 library would return a bogus result; on Solaris, it was possible to crash the
4620 interpreter. Patch by Stefan Krah.

Mark Dickinson36ecd672010-01-29 17:11:39 +00004632
Georg Brandlba83f822010-03-14 09:50:54 +00004633- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4634 and add the additional members returned in an OSVERSIONINFOEX structure. The
4635 new members are service_pack_major, service_pack_minor, suite_mask, and
4636 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00004637
Georg Brandlba83f822010-03-14 09:50:54 +00004638- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4639 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4640 returning NULL. The macro now returns a statically allocated empty string
4641 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00004642
Antoine Pitrou64672132010-01-13 07:55:48 +00004643- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00004650 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4651 strings,
4652 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4653 numeric strings corresponding to subnormal values,
4654 (3) a memory leak for some values large enough to cause overflow, and
4655 (4) a number of flaws that could lead to incorrectly rounded results.
4656

4658 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00004659

R. David Murray63e4fd72010-02-10 22:42:04 +00004672- Issue #7835: shelve should no longer produce mysterious warnings during
4673 interpreter shutdown.
4674
Georg Brandlba83f822010-03-14 09:50:54 +00004675- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4676 XML processing instructions and comments. These raw characters are allowed
4677 by the XML specification, and are necessary when outputting e.g. PHP code in
4678 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00004686- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004687 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004688 Also, raise ValueError rather than TypeError when an unknown TIPC address
4689 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004693- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004694 file position when calling `truncate()`. It would previously change the file
4695 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004696 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4697
Georg Brandlba83f822010-03-14 09:50:54 +00004698- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4699 class used to represent files stored inside an archive. The new
4700 implementation is significantly faster and can be wrapped in a
4701 ``io.BufferedReader`` object for more speedups. It also solves an issue
4702 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4703 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004712
Georg Brandlba83f822010-03-14 09:50:54 +00004713- Issue #7748: Since unicode values are supported for some metadata options in
4714 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4715 encoded string for them. This ensures that the upload and register commands
4716 send the correct values to PyPI without any error.

4792
Georg Brandlba83f822010-03-14 09:50:54 +00004793- The ``__complex__()`` method is now looked up on the class of instances to
4794 make it consistent with other special methods.

4798
Mark Dickinson1b34d252010-01-01 17:27:30 +00004799- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004800 DeprecationWarning when passed a float argument where an integer was expected.
4801 These functions and methods now raise TypeError instead. The majority of the
4802 effects of this change are in the extension modules, but some core functions
4803 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4804 and many unicode/str methods.

4818 of integers: the result of a/b is now correctly rounded for ints a and b (at
4819 least on IEEE 754 platforms), and in particular does not depend on the
4820 internal representation of a long.

4977 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004986- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4987 decimal string that's guaranteed to round back to x under correct rounding
4988 (with round-half-to-even rounding mode). Previously it gave a string based on
4989 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4990 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4991 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004993- Issue #7117: On almost all platforms: float-to-string and string-to-float
4994 conversions within Python are now correctly rounded. Places these conversions
4995 occur include: str for floats and complex numbers; the float and complex
4996 constructors; old-style and new-style numeric formatting; serialization and
4997 deserialization of floats and complex numbers using marshal, pickle and json;
4998 parsing of float and imaginary literals in Python code; Decimal-to-float
4999 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005000
Georg Brandlba83f822010-03-14 09:50:54 +00005001 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5002 providing correctly-rounded strtod and dtoa C functions. This code is
5003 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5004 the C compiler. There may be a small number of platforms on which correct
5005 operation of this code cannot be guaranteed, so the code is not used: notably,
5006 this applies to platforms where the C double format is not IEEE 754 binary64,
5007 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5008 and Python's configure script is unable to determine how to change the FPU
5009 precision. On these platforms conversions use the platform strtod and dtoa,
5010 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005012- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5013 uses the correctly-rounded string <-> float conversions described above (when
5014 available), and so produces correctly rounded results that will display nicely
5015 under the float repr. There are two related small changes: (1) round now
5016 accepts any class with an ``__index__()`` method for its second argument (but
5017 no longer accepts floats for the second argument), and (2) an excessively
5018 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5019 raises an exception.

5246 internal representation of integers, for performance reasons. Base 2**30 is
5247 enabled by default on 64-bit machines. Add --enable-big-digits option to

5434 gives improved memory leak detection when running under Valgrind, while taking
5435 advantage of pymalloc at other times.

6605 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6606 neither __int__ nor __long__, TypeError used to be raised (with a

6807 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6808 ``printf`` function, whereas PyString_FromFormat has an independent
6809 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006826- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006827 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006828 was correctly parsed but parsing of subsequent arguments failed.
6829
Vinay Sajip35e3b032008-09-01 14:33:59 +00006830- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006831 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6832 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6833 when given a tuple of classes as second argument, were looking up
6834 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6835 type object.
6836
Neal Norwitz18aa3882008-08-24 05:04:52 +00006837- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00006845- Silenced another compiler warning about a used but not defined
6846 function 'stringlib_contains_obj'.
6847
Benjamin Peterson712ee922008-08-24 18:10:20 +00006848- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00006906 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6907 for catch_warnings() also led to an improvement in the raising of a
6908 DeprecationWarning related to warnings.warn_explicit().
6909

6936
Benjamin Peterson37346b22008-08-23 20:27:43 +00006937- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006974What's New in Python 2.6 beta 3?
6975================================
6976
Barry Warsaw07a4a382008-08-21 01:15:08 +00006977*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006978
6979Core and Builtins
6980-----------------
6981
Guido van Rossumf8402962008-08-20 15:01:50 +00006982- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6983 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6984 extensions do not automatically benefit from the class attribute
6985 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6986 to their tp_flags field if they care. This is a backwards
6987 compatibility feature; in 3.0, all types will use the cache by
6988 default.
6989
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006990- Keyword arguments can now follow starred arguments. (``f(a, *args,
6991 keyword=23)`` is now valid syntax.)
6992
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006993- ctypes function pointers that are COM methods have a boolean True
6994 value again.
6995
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006996- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6997 by denying s# to parse objects that have a releasebuffer procedure,
6998 and introducing s*.
6999
Georg Brandl1e13ea92008-08-11 09:07:59 +00007000- Issue #3537: Fix an assertion failure when an empty but presized dict
7001 object was stored in the freelist.
7002
Mark Dickinsonb6467572008-08-04 21:30:09 +00007003- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7004 ValueError consistently across platforms.
7005
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007006- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7007 (64bit Unix, for example), unichr() would truncate its argument and return
7008 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7009
Neal Norwitze7d8be82008-07-31 17:17:14 +00007010- Apply security patches from Apple.
7011
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007012- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7013 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7014
Antoine Pitrou92f82162008-07-25 22:22:08 +00007015- Issue #1819: function calls with several named parameters are now on
7016 average 35% faster (as measured by pybench).
7017
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007018- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7019 the python debugger steps into a class statement: the free variables (local
7020 variables defined in an outer scope) would be deleted from the outer scope.
7021
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007022- Issue #2620: Overflow checking when allocating or reallocating memory
7023 was not always being done properly in some python types and extension
7024 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7025 all been updated to perform better checks and places in the code that
7026 would previously leak memory on the error path when such an allocation
7027 failed have been fixed.

7030-------
7031
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007032- Issue #3612: Added some missing basic types in ctypes.wintypes.
7033
Benjamin Petersone977ad42008-08-20 01:42:01 +00007034- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7035 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7036
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007037- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7038 version reported by these tools does not necessarily follow the python
7039 version numbering scheme, so the module is less strict when parsing it.
7040
Nick Coghlanf70385a2008-08-18 12:42:46 +00007041- Issue #2235: Added Py3k warnings for types which will become unhashable
7042 under the stricter __hash__ inheritance rules in 3.0. Several types
7043 which did not meet the rules for hash invariants and were already
7044 unhashable in 3.0 have now been explicitly flagged as unhashable in
7045 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7046 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7047
Brett Cannon88f801d2008-08-18 00:46:22 +00007048- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7049 imported into the module but exposed as part of the module's API.
7050
Brett Cannon7b96f072008-08-18 00:41:11 +00007051- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7052
Brett Cannon46225e72008-08-18 00:36:52 +00007053- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007055- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7056
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007057- Issue #3575: Incremental decoder's decode function now takes bytearray
7058 by using 's*' instead of 't#'.
7059
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007060- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007061 fails unicode conversion on 2nd parameter. (windows only)
7062
Georg Brandl222e2082010-08-01 22:27:39 +00007063- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007064 in a redirect.
7065
Brett Cannonabe423e2008-08-16 21:47:07 +00007066- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007067 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007068
Facundo Batistaeb90b782008-08-16 14:44:07 +00007069- Issue #2776: fixed small issue when handling an URL with double slash
7070 after a 302 response in the case of not going through a proxy.
7071
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007072- Issue #2676: in the email package, content-type parsing was hanging on
7073 pathological input because of quadratic or exponential behaviour of a
7074 regular expression.
7075
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007076- Issue #3476: binary buffered reading through the new "io" library is now
7077 thread-safe.
7078
Brett Cannonbf3157b2008-08-14 05:00:03 +00007079- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7080 since mimetools itself is deprecated. Because modules are cached, all
7081 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7082
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007083- Issue #3134: shutil referenced undefined WindowsError symbol.
7084
Robert Schuppenies14646332008-08-10 11:01:53 +00007085- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7086 menu entries were not deleted.
7087
Brett Cannon83e81842008-08-09 23:30:55 +00007088- Copied the implementation of reduce() to _functools.reduce() to have a
7089 version that did not raise a DeprecationWarning under -3.
7090
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007091- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7092 a MemoryError rather than silently stop the iteration.
7093
Guido van Rossum59ce9012008-08-09 14:55:34 +00007094- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7095 to _sre.compile() will now be rejected. This should not affect anybody
7096 since the re.compile() function never generates invalid re-bytecode.
7097
Skip Montanaroa032bf42008-08-08 22:52:51 +00007098- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7099 upon first access it can be automatically initialized from the csv file if
7100 it wasn't initialized during instantiation.
7101
Brett Cannon3aa2a492008-08-06 22:28:09 +00007102- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7103 the reload() built-in has been removed.
7104
Brett Cannon7e30b672008-08-04 21:52:25 +00007105- Changed code in the following modules/packages to remove warnings raised

7174-----------------
7175
Georg Brandl3e483f62008-07-16 22:57:41 +00007176- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7177 its methods now allow for items objects that can be converted to
7178 an integer using operator.index().
7179
Mark Dickinson64b7e502008-07-16 09:40:03 +00007180- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7181 produced a ValueError instead of giving the correct float.
7182
Eric Smitha5fa5a22008-07-16 00:11:49 +00007183- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7184 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7185
Mark Dickinson7103aa42008-07-15 19:08:33 +00007186- Issue #3008: the float type has a new instance method 'float.hex'
7187 and a new class method 'float.fromhex' to convert floating-point
7188 numbers to and from hexadecimal strings, respectively.
7189
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007190- Issue #2235: __hash__ is once again inherited by default. To allow
7191 collections.Hashable to remain meaningful in the presence of the
7192 default hash implementation (object.__hash__), it is now possible
7193 to explicit block inheritance of hash by setting __hash__=None at
7194 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7195 level.
7196
Nick Coghlanb028f502008-07-13 14:52:36 +00007197- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7198 the parent module cannot be found while performing an absolute import.
7199 This means that an incorrectly defined __package__ attribute will
7200 now only prevent relative imports in that module rather than causing
7201 all imports from that module to fail.
7202
Nick Coghlan14ff9942008-07-08 14:21:42 +00007203- Issue #2517: Allow unicode messages in Exceptions again by correctly

7213 another thread's dictionary.
7214
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007215- Issue #3004: Minor change to slice.indices(): the start and stop
7216 arguments are now treated identically, making the behaviour easier
7217 to describe and understand. For example, slice(None, -10,
7218 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7219 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7220 10, -1).

7263 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007264 wrong because the actual transmitted size could differ from the

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007281- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007672 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007673
7674 This is controlled by the configure argument ``--with-universal-archs``:
7675
7676 - ``--with-universal-archs=all``: install 4-way universal
7677
7678 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7679
7680 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7681
7682 This option should be used in combination with ``--enable-universalsdk=``.
7683
7684 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7688
Georg Brandl74a1dea2008-05-28 11:21:39 +00007689- Add ``PyType_Modified()`` as a public API to clear the type cache.
7690
7691- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007692
7693- The PyString functions have been renamed to PyBytes. A batch of
7694 defines were added so that the linker still sees the original
7695 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007733- Issue #1631171: Re-implement the 'warnings' module in C (the
7734 original Python code has been kept as backup). This will allow for
7735 using the 'warning's machinery in such places as the parser where
7736 use of pure Python code is not possible. Both the ``showarning()``
7737 and ``formatwarning()`` gain an optional 'line' argument which is
7738 not called by default for backwards-compatibility reasons. Setting
7739 ``warnings.showwarning()`` to an implementation that lacks support
7740 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007765- The getpass module has been improved on Unix. It now uses /dev/tty
7766 by default and uses stderr instead of stdout. A GetPassWarning is
7767 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007782- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007783 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007803- Issue #2550: The approach used by client/server code for obtaining
7804 ports to listen on in network-oriented tests has been refined in an
7805 effort to facilitate running multiple instances of the entire
7806 regression test suite in parallel without issue.
7807 test_support.bind_port() has been fixed such that it will always
7808 return a unique port -- which wasn't always the case with the
7809 previous implementation, especially if socket options had been set
7810 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7811 new implementation of bind_port() will actually raise an exception
7812 if it is passed an AF_INET/SOCK_STREAM socket with either the
7813 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7814 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7815 the socket it's been passed. This currently only applies to
7816 Windows. This option prevents any other sockets from binding to the
7817 host/port we've bound to, thus removing the possibility of the
7818 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7819 when a second SOCK_STREAM socket binds and accepts to a host/port
7820 that's already been bound by another socket. The optional preferred
7821 port parameter to bind_port() has been removed. Under no
7822 circumstances should tests be hard coding ports!
7823
7824 test_support.find_unused_port() has also been introduced, which will
7825 pass a temporary socket object to bind_port() in order to obtain an
7826 unused port. The temporary socket object is then closed and
7827 deleted, and the port is returned. This method should only be used
7828 for obtaining an unused port in order to pass to an external program
7829 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7830 a parameter to a server-oriented class that doesn't give you direct
7831 access to the underlying socket used.
7832
7833 Finally, test_support.HOST has been introduced, which should be used
7834 for the host argument of any relevant socket calls (i.e. bind and
7835 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007836
7837 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007839 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7840 test_asynchat and test_socket_ssl.
7841
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842 It is now possible for multiple instances of the regression test
7843 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008122- Added the future_builtins module, which contains hex() and oct().
8123 These are the PEP 3127 version of these functions, designed to be
8124 compatible with the hex() and oct() builtins from Python 3.0. They
8125 differ slightly in their output formats from the existing, unchanged
8126 Python 2.6 builtins. The expected usage of the future_builtins
8127 module is:
8128 from future_builtins import hex, oct
8129
Eric Smith7ef40bf2008-02-20 23:34:22 +00008130- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8131 exponents for exponents with absolute value < 100. Follows C99
8132 standard. This is a change on Windows, which would use 3 digits.
8133 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8134 so that any alterations it does to the resulting string will be
8135 available in stringlib/formatter.h (for float.__format__).
8136
Eric Smith5a3c1352008-02-19 13:21:56 +00008137- Implemented PEP 3101, Advanced String Formatting. This adds a new
8138 builtin format(); a format() method for str and unicode; a
8139 __format__() method to object, str, unicode, int, long, float, and
8140 datetime; the class string.Formatter; and the C API
8141 PyObject_Format().
8142
Georg Brandl3ee81df2008-05-17 18:14:43 +00008143- Fixed several potential crashes, all caused by specially crafted
8144 __del__ methods exploiting objects in temporarily inconsistent
8145 state.

8156 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008157
Georg Brandl3ee81df2008-05-17 18:14:43 +00008158- Issue #2045: Fix an infinite recursion triggered when printing a
8159 subclass of collections.defaultdict, if its default_factory is set
8160 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008161
Christian Heimesf75dbef2008-02-08 00:11:31 +00008162- Fixed a minor memory leak in dictobject.c. The content of the free
8163 list was not freed on interpreter shutdown.
8164

8171
Georg Brandl3ee81df2008-05-17 18:14:43 +00008172- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8173 calls. Python expected the return type int but the fork familie
8174 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008188- Patch #1473257: generator objects gain a gi_code attribute. This is
8189 the same object as the func_code attribute of the function that
8190 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008191
Georg Brandl3ee81df2008-05-17 18:14:43 +00008192- Issue #1920: "while 0" statements were completely removed by the
8193 compiler, even in the presence of an "else" clause, which is
8194 supposed to be run when the condition is false. Now the compiler
8195 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008196
Guido van Rossumeead05f2008-01-24 18:21:02 +00008197- A few crashers fixed: weakref_in_del.py (issue #1377858);
8198 loosing_dict_ref.py (issue #1303614, test67.py);
8199 borrowed_ref_[34].py (not in tracker).
8200
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008201- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008202 suppressed while an extension is loaded by calling SetErrorMode in
8203 dynload_win.c. The error is still reported properly.
8204
Georg Brandl3ee81df2008-05-17 18:14:43 +00008205- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008206 several extension methods and modules do not work without unicode
8207 support.
8208
Georg Brandl26543b12008-01-21 18:36:51 +00008209- Issue #1882: when compiling code from a string, encoding cookies in the
8210 second line of code were not always recognized correctly.
8211
Georg Brandl14404b62008-01-19 19:27:05 +00008212- Issue #1679: "0x" was taken as a valid integer literal.
8213
Georg Brandl6caad7d2008-01-26 14:19:22 +00008214- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008215 added.
8216
Christian Heimesc94e2b52008-01-14 04:13:37 +00008217- sys.float_info / PyFloat_GetInfo: The floating point information
8218 object was converted from a dict to a specialized structseq object.
8219
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220- Patch #1816: Added sys.flags structseq. It exposes the status of
8221 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008222
Georg Brandl3ee81df2008-05-17 18:14:43 +00008223- Objects/structseq.c: Implemented new structseq representation. The
8224 patch makes structseqs (e.g. the return value of os.stat) more
8225 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Patch #1700288: added a type attribute cache that caches method
8228 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008229
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008230- Bug #1776: __import__() no longer accepts filenames on any platform.
8231 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008232
Georg Brandlaed6c662008-01-07 17:25:53 +00008233- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8234
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8236 envvar and sys.dont_write_bytecode attribute. All these can be set
8237 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Improve some exception messages when Windows fails to load an
8240 extension module. Now we get for example '%1 is not a valid Win32
8241 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008242
Georg Brandl3ee81df2008-05-17 18:14:43 +00008243- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008245- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8246 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008247
Christian Heimes0a8143f2007-12-18 23:22:54 +00008248- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249 and INF. float("nan"), float("inf") and float("-inf") now work on
8250 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Compiler now generates simpler and faster code for dictionary
8253 literals. The oparg for BUILD_MAP now indicates an estimated
8254 dictionary size. There is a new opcode, STORE_MAP, for adding
8255 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008262- Issue #1538: Avoid copying string in split/rsplit if the split char
8263 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008264
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008265- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008266 SystemError.
8267
Nick Coghlanef01d822007-12-03 12:55:17 +00008268- PEP 366: Allow explicit relative imports when executing modules
8269 inside packages with the -m switch via a new module level
8270 __package__ attribute.
8271
Georg Brandl3ee81df2008-05-17 18:14:43 +00008272- Issue #1402: Fix a crash on exit, when another thread is still
8273 running, and if the deallocation of its frames somehow calls the
8274 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008275

8280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Issue #1460: The utf-7 incremental decoder did not accept truncated
8282 input. It now correctly saves its state between chunks of data.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008284- Patch #1739468: Directories and zipfiles containing a __main__.py
8285 file can now be directly executed by passing their name to the
8286 interpreter. The directory/zipfile is automatically inserted as the
8287 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Issue #1265: Fix a problem with sys.settrace, if the tracing
8290 function uses a generator expression when at the same time the
8291 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008292
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008293- sets and frozensets now have an isdisjoint() method.
8294
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008295- optimize the performance of builtin.sum().
8296
Neal Norwitz44f326e2007-10-05 05:29:17 +00008297- Fix warnings found by the new version of the Coverity checker.
8298
Georg Brandl21e99f42010-03-07 15:23:59 +00008299- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8301 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008302
Georg Brandl3ee81df2008-05-17 18:14:43 +00008303- Issue #1686386: Tuple's tp_repr did not take into account the
8304 possibility of having a self-referential tuple, which is possible
8305 from C code. Nor did object's tp_str consider that a type's tp_str
8306 could do something that could lead to an inifinite recursion.
8307 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8308 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008309
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Issue #1164: It was possible to trigger deadlock when using the
8311 'print' statement to write to a file since the GIL was not released
8312 as needed. Now PyObject_Print() does the right thing along with
8313 various tp_print implementations of the built-in types and those in
8314 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008315
Georg Brandl3ee81df2008-05-17 18:14:43 +00008316- Issue #1147: Exceptions were directly allowing string exceptions in
8317 their throw() method even though string exceptions no longer
8318 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008319
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- Issue #1096: Prevent a segfault from getting the repr of a very
8321 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008322
Brett Cannon1e534b52007-09-07 04:18:30 +00008323- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008324 PyObject_Call() never calling back out to Python code to trigger
8325 recursion depth updates/checks. Required the creation of a static
8326 RuntimeError instance in case normalizing an exception put the
8327 recursion check value past its limit. Fixes crashers
8328 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008329
Georg Brandl3ee81df2008-05-17 18:14:43 +00008330- Patch #1031213: Decode source line in SyntaxErrors back to its

8334 with %G.
8335
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00008343- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 __*__ attributes. (Some already existed, e.g., __doc__ and
8345 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008346
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008347- Add -3 option to the interpreter to warn about features that are
8348 deprecated and will be changed/removed in Python 3.0.
8349
Georg Brandl2134e752007-05-21 20:34:16 +00008350- Patch #1686487: you can now pass any mapping after '**' in function
8351 calls.
8352
Collin Winter62903052007-05-18 23:11:24 +00008353- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008354 "except E as target:". This is to provide forwards compatibility
8355 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008356
Brett Cannon229cee22007-05-05 01:34:02 +00008357- Deprecate BaseException.message as per PEP 352.
8358
Georg Brandl3ee81df2008-05-17 18:14:43 +00008359- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008360 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008361
Vinay Sajip8549ce32007-05-06 17:53:37 +00008362- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008363 setting a plain string, ie don't expand to single letter identifiers.
8364
Raymond Hettinger13936692007-04-11 18:40:58 +00008365- Request #1191699: Slices can now be pickled.
8366
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008367- Request #1193128: str.translate() now allows a None argument for
8368 translations that only remove characters without re-mapping the
8369 remaining characters.
8370
Georg Brandl5cb76c12007-03-21 09:00:39 +00008371- Patch #1682205: a TypeError while unpacking an iterable is no longer
8372 masked by a generic one with the message "unpack non-sequence".
8373
Neal Norwitzaa754b72007-03-21 06:39:48 +00008374- Remove unused file Python/fmod.c.
8375
Guido van Rossum143b5642007-03-23 04:58:42 +00008376- Bug #1683368: The object.__init__() and object.__new__() methods are
8377 now stricter in rejecting excess arguments. The only time when
8378 either allows excess arguments is when it is not overridden and the
8379 other one is. For backwards compatibility, when both are
8380 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008381 warning later). Also, type.__init__() insists on the same signature
8382 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008383
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8385 object to complex using its __complex__() method before falling back
8386 to the __float__() method. Therefore, the functions in the cmath
8387 module now can operate on objects that define a __complex__()
8388 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008389
Georg Brandl3ee81df2008-05-17 18:14:43 +00008390- Patch #1623563: allow __class__ assignment for classes with
8391 __slots__. The old and the new class are still required to have the
8392 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008393

8398 ``object.__reduce_ex__()`` is called with an object that is faking
8399 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008400
Georg Brandl3ee81df2008-05-17 18:14:43 +00008401- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008404- Patch #1444529: the builtin compile() now accepts keyword arguments.
8405
Georg Brandl7b9c5552007-03-12 14:30:05 +00008406- Bug #1678647: write a newline after printing an exception in any
8407 case, even when converting the value to a string failed.
8408
Georg Brandl871f1bc2007-03-12 13:17:36 +00008409- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008410 its argument, if it exists. If not, it will work like before. This
8411 allows customizing the output of dir() in the presence of a
8412 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008414- Patch #922167: Python no longer segfaults when faced with infinitely
8415 self-recursive reload() calls (as reported by bug #742342).
8416
Georg Brandl3ee81df2008-05-17 18:14:43 +00008417- Patch #1675981: remove unreachable code from ``type.__new__()``
8418 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008420- Patch #1491866: change the complex() constructor to allow
8421 parthensized forms. This means complex(repr(x)) now works instead of
8422 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008423
Georg Brandlaa2321b2007-03-07 00:40:28 +00008424- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008425 makes the filenames the warning module prints much more sensible

8933
Facundo Batistad918a652007-04-24 13:54:38 +00008934- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008935 the client's request was successfully received, understood, and
8936 accepted. Now in these cases no error is raised in urllib (issue
8937 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008938

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008945- Added a timeout parameter to the constructor of other protocols
8946 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8947 work started with create_connection() and timeout in httplib, and
8948 closes patch #723312.
8949
Vinay Sajip8549ce32007-05-06 17:53:37 +00008950- Patch #1676823: Added create_connection() to socket.py, which may be
8951 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008952 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008953
Martin v. Löwis0af33882007-03-23 13:27:15 +00008954- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8974
Georg Brandlf66b6032007-03-14 08:27:52 +00008975- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008976 AttributeError instead of an IOError when the server's response
8977 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008978
Georg Brandl3ee81df2008-05-17 18:14:43 +00008979- Patch #957650: "%var%" environment variable references are now
8980 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008982
Georg Brandl3ee81df2008-05-17 18:14:43 +00008983- Patch #1429539: pdb now correctly initializes the __main__ module
8984 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008985 correctly now.
8986
Georg Brandlbad6f192007-03-13 21:32:56 +00008987- The nonobvious commands.getstatus() function is now deprecated.

8993
Georg Brandl3ee81df2008-05-17 18:14:43 +00008994- Patch #1530482: add pydoc.render_doc() which returns the
8995 documentation for a thing instead of paging it to stdout, which
8996 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008997
Georg Brandl3ee81df2008-05-17 18:14:43 +00008998- Patch #1533909: the timeit module now accepts callables in addition

9004 parameter which can be set to False to prevent the default
9005 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00009006
Georg Brandl9e6b4702007-03-13 18:15:41 +00009007- Patch #1581073: add a flag to textwrap that prevents the dropping of
9008 whitespace while wrapping.
9009
Georg Brandl92a6bae2007-03-13 17:43:32 +00009010- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009011 are set for invalid interpolation sequences that would lead to
9012 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009013

9026
Georg Brandl94fe3f52007-03-13 09:32:11 +00009027- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00009028 field names in its exception message if you try to write a record
9029 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00009047

9055 returned string up to the first NUL character.

9066
Georg Brandl3ee81df2008-05-17 18:14:43 +00009067- unittest now verifies more of its assumptions. In particular,
9068 TestCase and TestSuite subclasses (not instances) are no longer
9069 accepted in TestSuite.addTest(). This should cause no
9070 incompatibility since it never made sense with ordinary subclasses
9071 -- the failure just occurred later, with a more cumbersome
9072 exception.

9081 given a unicode argument and os.listdir() returns unicode filenames.
9082
Georg Brandl3ee81df2008-05-17 18:14:43 +00009083- Patch #1673619: setup.py identifies extension modules it doesn't

9085 build.

9437 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9438 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009454- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009455 time so that opening a database previously created with the DB_DUP
9456 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9457 opens. Specifically: dictionary assignment to a DB object will
9458 replace all values for a given key when the database allows
9459 duplicate values. DB users should use DB.put(k, v) when they want
9460 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009461

9467 characters with ASCII value less than 32. Also, it correctly quotes
9468 dots only if they occur on a single line, as opposed to the previous
9469 behavior of quoting dots if they are the second character of any
9470 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009471
