Florent Xiclunac2279652012-02-12 14:49:03 +0100336- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100337 has left two versions of customize_compiler, the original in
338 distutils.sysconfig and another copy in distutils.ccompiler, with some
339 parts of distutils calling one and others using the other.
340 Complete the revert back to only having one in distutils.sysconfig as
341 is the case in 3.x.
342
Ned Deily0d0ea482012-02-10 12:59:06 +0100343- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
344 Distutils-based packages with C extension modules may fail because
345 Apple has removed gcc-4.2, the version used to build python.org
346 64-bit/32-bit Pythons. If the user does not explicitly override
347 the default C compiler by setting the CC environment variable,
348 Distutils will now attempt to compile extension modules with clang
349 if gcc-4.2 is required but not found. Also as a convenience, if
350 the user does explicitly set CC, substitute its value as the default
351 compiler in the Distutils LDSHARED configuration variable for OS X.
352 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
353 SDK, neither of which are available in Xcode 4. This change does not
354 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700627- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
628 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
629 interpreter process. This could cause failures in non-Distutils subprocesses
630 and was unreliable since tests or user programs could modify the interpreter
631 environment after Distutils set it. Instead, have Distutils set the the
632 deployment target only in the environment of each build subprocess. It is
633 still possible to globally override the default by setting
634 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
635 greater or equal to the default value, the value with which the interpreter
636 was built.

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

2076
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002077- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2078 start byte and the continuation byte(s) are now considered invalid, instead
2079 of the number of bytes specified by the start byte.
2080 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2081 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2082 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2083 Previous versions returned a single u'\ufffd'.
2084
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002085- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002086 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2087 arises from the "Overriding __eq__ blocks inheritance ..." warning
2088 when turned into an exception: in this case the exception simply
2089 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002090
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002091- Issue #8748: Fix two issues with comparisons between complex and integer
2092 objects. (1) The comparison could incorrectly return True in some cases
2093 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2094 (2) The comparison raised an OverflowError for large integers, leading
2095 to unpredictable exceptions when combining integers and complex objects
2096 in sets or dicts.
2097
Mark Dickinson81336372010-05-30 12:12:25 +00002098- Issue #5211: Implicit coercion for the complex type is now completely
2099 removed. (Coercion for arithmetic operations was already removed in 2.7
2100 alpha 4, but coercion for rich comparisons was accidentally left in.)
2101
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002102- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

2104
Georg Brandlfee0f442010-05-22 21:26:21 +00002105- Issue #7902: When using explicit relative import syntax, don't try implicit

2464
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002465- Issue #8329: Don't return the same lists from select.select when no fds are
2466 changed.
2467
Georg Brandlfee0f442010-05-22 21:26:21 +00002468- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002469 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00002478- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2479 with a non-empty format string. This is an effort to future-proof user
2480 code. If a derived class does not currently implement __format__ but later
2481 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002482 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002483 Python 3.3 and it will be an error in Python 3.4.

2534 InvalidOperation instead of returning False. (Comparisons involving a quiet
2535 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlfee0f442010-05-22 21:26:21 +00002538- Issue #2531: Comparison operations between floats and Decimal instances now
2539 return a result based on the numeric values of the operands; previously they

Georg Brandlba83f822010-03-14 09:50:54 +00002854- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00002855 thread could raise an incorrect RuntimeError about not holding the import
2856 lock. The import lock is now reinitialized after fork.

Georg Brandlba83f822010-03-14 09:50:54 +00002877- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00002878 is run with the -OO flag. Tests requiring docstrings are skipped.
2879
Georg Brandlba83f822010-03-14 09:50:54 +00002880- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2881 now also used by regrtest to run all the tests in a temporary directory. The
2882 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2883 Xicluna who helped with the patch.

2900 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002901 library would return a bogus result; on Solaris, it was possible to crash the
2902 interpreter. Patch by Stefan Krah.

Mark Dickinson36ecd672010-01-29 17:11:39 +00002914
Georg Brandlba83f822010-03-14 09:50:54 +00002915- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2916 and add the additional members returned in an OSVERSIONINFOEX structure. The
2917 new members are service_pack_major, service_pack_minor, suite_mask, and
2918 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00002919
Georg Brandlba83f822010-03-14 09:50:54 +00002920- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2921 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2922 returning NULL. The macro now returns a statically allocated empty string
2923 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00002924
Antoine Pitrou64672132010-01-13 07:55:48 +00002925- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00002932 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
2933 strings,
2934 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2935 numeric strings corresponding to subnormal values,
2936 (3) a memory leak for some values large enough to cause overflow, and
2937 (4) a number of flaws that could lead to incorrectly rounded results.
2938
2939- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
2940 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00002941

2953
R. David Murray63e4fd72010-02-10 22:42:04 +00002954- Issue #7835: shelve should no longer produce mysterious warnings during
2955 interpreter shutdown.
2956
Georg Brandlba83f822010-03-14 09:50:54 +00002957- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
2958 XML processing instructions and comments. These raw characters are allowed
2959 by the XML specification, and are necessary when outputting e.g. PHP code in
2960 a processing instruction. Patch by Neil Muller.

Georg Brandlba83f822010-03-14 09:50:54 +00002966- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00002967
Antoine Pitroud840e512010-02-04 20:20:18 +00002968- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002969 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002970 Also, raise ValueError rather than TypeError when an unknown TIPC address
2971 type is specified. Patch by Brian Curtin.
2972
Vinay Sajip28c382f2010-02-04 18:48:53 +00002973- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002975- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002976 file position when calling `truncate()`. It would previously change the file
2977 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002978 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2979
Georg Brandlba83f822010-03-14 09:50:54 +00002980- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2981 class used to represent files stored inside an archive. The new
2982 implementation is significantly faster and can be wrapped in a
2983 ``io.BufferedReader`` object for more speedups. It also solves an issue
2984 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2985 Patch by Nir Aides.

2993 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00002994
Georg Brandlba83f822010-03-14 09:50:54 +00002995- Issue #7748: Since unicode values are supported for some metadata options in
2996 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2997 encoded string for them. This ensures that the upload and register commands
2998 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003081- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003082 DeprecationWarning when passed a float argument where an integer was expected.
3083 These functions and methods now raise TypeError instead. The majority of the
3084 effects of this change are in the extension modules, but some core functions
3085 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3086 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003269- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3270 decimal string that's guaranteed to round back to x under correct rounding
3271 (with round-half-to-even rounding mode). Previously it gave a string based on
3272 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3273 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3274 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003276- Issue #7117: On almost all platforms: float-to-string and string-to-float
3277 conversions within Python are now correctly rounded. Places these conversions
3278 occur include: str for floats and complex numbers; the float and complex
3279 constructors; old-style and new-style numeric formatting; serialization and
3280 deserialization of floats and complex numbers using marshal, pickle and json;
3281 parsing of float and imaginary literals in Python code; Decimal-to-float
3282 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003283
Georg Brandlba83f822010-03-14 09:50:54 +00003284 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3285 providing correctly-rounded strtod and dtoa C functions. This code is
3286 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3287 the C compiler. There may be a small number of platforms on which correct
3288 operation of this code cannot be guaranteed, so the code is not used: notably,
3289 this applies to platforms where the C double format is not IEEE 754 binary64,
3290 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3291 and Python's configure script is unable to determine how to change the FPU
3292 precision. On these platforms conversions use the platform strtod and dtoa,
3293 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003295- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3296 uses the correctly-rounded string <-> float conversions described above (when
3297 available), and so produces correctly rounded results that will display nicely
3298 under the float repr. There are two related small changes: (1) round now
3299 accepts any class with an ``__index__()`` method for its second argument (but
3300 no longer accepts floats for the second argument), and (2) an excessively
3301 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3302 raises an exception.

3529 internal representation of integers, for performance reasons. Base 2**30 is
3530 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00003715- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3717 gives improved memory leak detection when running under Valgrind, while taking
3718 advantage of pymalloc at other times.

4885 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4886 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005085- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5087 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5088 ``printf`` function, whereas PyString_FromFormat has an independent
5089 implementation and uses "%zd" on all platforms for size_t values.
5090 This makes a difference on win64, where ``printf`` needs "%Id" to display

Vinay Sajip35e3b032008-09-01 14:33:59 +00005107 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005108 was correctly parsed but parsing of subsequent arguments failed.
5109
Vinay Sajip35e3b032008-09-01 14:33:59 +00005110- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005111 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5112 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5113 when given a tuple of classes as second argument, were looking up
5114 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5115 type object.
5116
Neal Norwitz18aa3882008-08-24 05:04:52 +00005117- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00005125- Silenced another compiler warning about a used but not defined
5126 function 'stringlib_contains_obj'.
5127
Benjamin Peterson712ee922008-08-24 18:10:20 +00005128- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5129 ``__delslice__``.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005186 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5187 for catch_warnings() also led to an improvement in the raising of a
5188 DeprecationWarning related to warnings.warn_explicit().
5189

5212
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005213- Issue #2975: When compiling several extension modules with Visual Studio 2008
5214 from the same python interpreter, some environment variables would grow
5215 without limit.
5216
Benjamin Peterson37346b22008-08-23 20:27:43 +00005217- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005254What's New in Python 2.6 beta 3?
5255================================
5256
Barry Warsaw07a4a382008-08-21 01:15:08 +00005257*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005258
5259Core and Builtins
5260-----------------
5261
Guido van Rossumf8402962008-08-20 15:01:50 +00005262- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5263 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5264 extensions do not automatically benefit from the class attribute
5265 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5266 to their tp_flags field if they care. This is a backwards
5267 compatibility feature; in 3.0, all types will use the cache by
5268 default.
5269
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005270- Keyword arguments can now follow starred arguments. (``f(a, *args,
5271 keyword=23)`` is now valid syntax.)
5272
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005273- ctypes function pointers that are COM methods have a boolean True
5274 value again.
5275
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005276- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5277 by denying s# to parse objects that have a releasebuffer procedure,
5278 and introducing s*.
5279
Georg Brandl1e13ea92008-08-11 09:07:59 +00005280- Issue #3537: Fix an assertion failure when an empty but presized dict
5281 object was stored in the freelist.
5282
Mark Dickinsonb6467572008-08-04 21:30:09 +00005283- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5284 ValueError consistently across platforms.
5285
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005286- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5287 (64bit Unix, for example), unichr() would truncate its argument and return
5288 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5289
Neal Norwitze7d8be82008-07-31 17:17:14 +00005290- Apply security patches from Apple.
5291
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005292- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5293 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5294
Antoine Pitrou92f82162008-07-25 22:22:08 +00005295- Issue #1819: function calls with several named parameters are now on
5296 average 35% faster (as measured by pybench).
5297
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005298- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5299 the python debugger steps into a class statement: the free variables (local
5300 variables defined in an outer scope) would be deleted from the outer scope.
5301
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005302- Issue #2620: Overflow checking when allocating or reallocating memory
5303 was not always being done properly in some python types and extension
5304 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5305 all been updated to perform better checks and places in the code that
5306 would previously leak memory on the error path when such an allocation
5307 failed have been fixed.

5310-------
5311
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005312- Issue #3612: Added some missing basic types in ctypes.wintypes.
5313
Benjamin Petersone977ad42008-08-20 01:42:01 +00005314- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5315 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5316
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005317- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5318 version reported by these tools does not necessarily follow the python
5319 version numbering scheme, so the module is less strict when parsing it.
5320
Nick Coghlanf70385a2008-08-18 12:42:46 +00005321- Issue #2235: Added Py3k warnings for types which will become unhashable
5322 under the stricter __hash__ inheritance rules in 3.0. Several types
5323 which did not meet the rules for hash invariants and were already
5324 unhashable in 3.0 have now been explicitly flagged as unhashable in
5325 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5326 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5327
Brett Cannon88f801d2008-08-18 00:46:22 +00005328- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5329 imported into the module but exposed as part of the module's API.
5330
Brett Cannon7b96f072008-08-18 00:41:11 +00005331- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5332
Brett Cannon46225e72008-08-18 00:36:52 +00005333- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005335- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5336
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005337- Issue #3575: Incremental decoder's decode function now takes bytearray
5338 by using 's*' instead of 't#'.
5339
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005340- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005341 fails unicode conversion on 2nd parameter. (windows only)
5342
Georg Brandl222e2082010-08-01 22:27:39 +00005343- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005344 in a redirect.
5345
Brett Cannonabe423e2008-08-16 21:47:07 +00005346- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005347 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005348
Facundo Batistaeb90b782008-08-16 14:44:07 +00005349- Issue #2776: fixed small issue when handling an URL with double slash
5350 after a 302 response in the case of not going through a proxy.
5351
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005352- Issue #2676: in the email package, content-type parsing was hanging on
5353 pathological input because of quadratic or exponential behaviour of a
5354 regular expression.
5355
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005356- Issue #3476: binary buffered reading through the new "io" library is now
5357 thread-safe.
5358
Brett Cannonbf3157b2008-08-14 05:00:03 +00005359- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5360 since mimetools itself is deprecated. Because modules are cached, all
5361 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5362
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005363- Issue #3134: shutil referenced undefined WindowsError symbol.
5364
Robert Schuppenies14646332008-08-10 11:01:53 +00005365- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5366 menu entries were not deleted.
5367
Brett Cannon83e81842008-08-09 23:30:55 +00005368- Copied the implementation of reduce() to _functools.reduce() to have a
5369 version that did not raise a DeprecationWarning under -3.
5370
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005371- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5372 a MemoryError rather than silently stop the iteration.
5373
Guido van Rossum59ce9012008-08-09 14:55:34 +00005374- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5375 to _sre.compile() will now be rejected. This should not affect anybody
5376 since the re.compile() function never generates invalid re-bytecode.
5377
Skip Montanaroa032bf42008-08-08 22:52:51 +00005378- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5379 upon first access it can be automatically initialized from the csv file if
5380 it wasn't initialized during instantiation.
5381
Brett Cannon3aa2a492008-08-06 22:28:09 +00005382- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5383 the reload() built-in has been removed.
5384
Brett Cannon7e30b672008-08-04 21:52:25 +00005385- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005386 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005387 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

5454-----------------
5455
Georg Brandl3e483f62008-07-16 22:57:41 +00005456- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5457 its methods now allow for items objects that can be converted to
5458 an integer using operator.index().
5459
Mark Dickinson64b7e502008-07-16 09:40:03 +00005460- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5461 produced a ValueError instead of giving the correct float.
5462
Eric Smitha5fa5a22008-07-16 00:11:49 +00005463- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5464 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5465
Mark Dickinson7103aa42008-07-15 19:08:33 +00005466- Issue #3008: the float type has a new instance method 'float.hex'
5467 and a new class method 'float.fromhex' to convert floating-point
5468 numbers to and from hexadecimal strings, respectively.
5469
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005470- Issue #2235: __hash__ is once again inherited by default. To allow
5471 collections.Hashable to remain meaningful in the presence of the
5472 default hash implementation (object.__hash__), it is now possible
5473 to explicit block inheritance of hash by setting __hash__=None at
5474 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5475 level.
5476
Nick Coghlanb028f502008-07-13 14:52:36 +00005477- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5478 the parent module cannot be found while performing an absolute import.
5479 This means that an incorrectly defined __package__ attribute will
5480 now only prevent relative imports in that module rather than causing
5481 all imports from that module to fail.
5482
Nick Coghlan14ff9942008-07-08 14:21:42 +00005483- Issue #2517: Allow unicode messages in Exceptions again by correctly

5493 another thread's dictionary.
5494
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005495- Issue #3004: Minor change to slice.indices(): the start and stop
5496 arguments are now treated identically, making the behaviour easier
5497 to describe and understand. For example, slice(None, -10,
5498 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5499 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5500 10, -1).
5501
Georg Brandl278fc502008-07-19 12:46:12 +00005502- Issue #3219: Calling a function with repeated keyword arguments,
5503 f(a=2, a=23), would not cause a syntax error. This was a regression
5504 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005542- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5543 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005544 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005545 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005561- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5956 This is controlled by the configure argument ``--with-universal-archs``:
5957
5958 - ``--with-universal-archs=all``: install 4-way universal
5959
5960 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5961
5962 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5963
5964 This option should be used in combination with ``--enable-universalsdk=``.
5965
5966 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- Issue #1631171: Re-implement the 'warnings' module in C (the
6017 original Python code has been kept as backup). This will allow for
6018 using the 'warning's machinery in such places as the parser where
6019 use of pure Python code is not possible. Both the ``showarning()``
6020 and ``formatwarning()`` gain an optional 'line' argument which is
6021 not called by default for backwards-compatibility reasons. Setting
6022 ``warnings.showwarning()`` to an implementation that lacks support
6023 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006065- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006066 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006086- Issue #2550: The approach used by client/server code for obtaining
6087 ports to listen on in network-oriented tests has been refined in an
6088 effort to facilitate running multiple instances of the entire
6089 regression test suite in parallel without issue.
6090 test_support.bind_port() has been fixed such that it will always
6091 return a unique port -- which wasn't always the case with the
6092 previous implementation, especially if socket options had been set
6093 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6094 new implementation of bind_port() will actually raise an exception
6095 if it is passed an AF_INET/SOCK_STREAM socket with either the
6096 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6097 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6098 the socket it's been passed. This currently only applies to
6099 Windows. This option prevents any other sockets from binding to the
6100 host/port we've bound to, thus removing the possibility of the
6101 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6102 when a second SOCK_STREAM socket binds and accepts to a host/port
6103 that's already been bound by another socket. The optional preferred
6104 port parameter to bind_port() has been removed. Under no
6105 circumstances should tests be hard coding ports!
6106
6107 test_support.find_unused_port() has also been introduced, which will
6108 pass a temporary socket object to bind_port() in order to obtain an
6109 unused port. The temporary socket object is then closed and
6110 deleted, and the port is returned. This method should only be used
6111 for obtaining an unused port in order to pass to an external program
6112 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6113 a parameter to a server-oriented class that doesn't give you direct
6114 access to the underlying socket used.
6115
6116 Finally, test_support.HOST has been introduced, which should be used
6117 for the host argument of any relevant socket calls (i.e. bind and
6118 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006119
6120 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006121 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006122 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6123 test_asynchat and test_socket_ssl.
6124
Georg Brandl3ee81df2008-05-17 18:14:43 +00006125 It is now possible for multiple instances of the regression test
6126 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006405- Added the future_builtins module, which contains hex() and oct().
6406 These are the PEP 3127 version of these functions, designed to be
6407 compatible with the hex() and oct() builtins from Python 3.0. They
6408 differ slightly in their output formats from the existing, unchanged
6409 Python 2.6 builtins. The expected usage of the future_builtins
6410 module is:
6411 from future_builtins import hex, oct
6412
Eric Smith7ef40bf2008-02-20 23:34:22 +00006413- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6414 exponents for exponents with absolute value < 100. Follows C99
6415 standard. This is a change on Windows, which would use 3 digits.
6416 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6417 so that any alterations it does to the resulting string will be
6418 available in stringlib/formatter.h (for float.__format__).
6419
Eric Smith5a3c1352008-02-19 13:21:56 +00006420- Implemented PEP 3101, Advanced String Formatting. This adds a new
6421 builtin format(); a format() method for str and unicode; a
6422 __format__() method to object, str, unicode, int, long, float, and
6423 datetime; the class string.Formatter; and the C API
6424 PyObject_Format().
6425
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426- Fixed several potential crashes, all caused by specially crafted
6427 __del__ methods exploiting objects in temporarily inconsistent
6428 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006429
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006430- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006431 prevent a possible crash: an Abstract Base Class would try to access
6432 a slot on a registered virtual subclass.

6439 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006440
Georg Brandl3ee81df2008-05-17 18:14:43 +00006441- Issue #2045: Fix an infinite recursion triggered when printing a
6442 subclass of collections.defaultdict, if its default_factory is set
6443 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006444
Christian Heimesf75dbef2008-02-08 00:11:31 +00006445- Fixed a minor memory leak in dictobject.c. The content of the free
6446 list was not freed on interpreter shutdown.
6447
Georg Brandl21e99f42010-03-07 15:23:59 +00006448- Limit free list of method and built-in function objects to 256

6452 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006453 to compact the internal free lists of pre-allocted ints and floats.
6454
Georg Brandl3ee81df2008-05-17 18:14:43 +00006455- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6456 calls. Python expected the return type int but the fork familie
6457 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006458

6472 the same object as the func_code attribute of the function that
6473 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006474
Georg Brandl3ee81df2008-05-17 18:14:43 +00006475- Issue #1920: "while 0" statements were completely removed by the
6476 compiler, even in the presence of an "else" clause, which is
6477 supposed to be run when the condition is false. Now the compiler
6478 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006479
Guido van Rossumeead05f2008-01-24 18:21:02 +00006480- A few crashers fixed: weakref_in_del.py (issue #1377858);
6481 loosing_dict_ref.py (issue #1303614, test67.py);
6482 borrowed_ref_[34].py (not in tracker).
6483
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006484- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006485 suppressed while an extension is loaded by calling SetErrorMode in
6486 dynload_win.c. The error is still reported properly.
6487
Georg Brandl3ee81df2008-05-17 18:14:43 +00006488- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006489 several extension methods and modules do not work without unicode
6490 support.
6491
Georg Brandl26543b12008-01-21 18:36:51 +00006492- Issue #1882: when compiling code from a string, encoding cookies in the
6493 second line of code were not always recognized correctly.
6494
Georg Brandl14404b62008-01-19 19:27:05 +00006495- Issue #1679: "0x" was taken as a valid integer literal.
6496
Georg Brandl6caad7d2008-01-26 14:19:22 +00006497- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006498 added.
6499
Christian Heimesc94e2b52008-01-14 04:13:37 +00006500- sys.float_info / PyFloat_GetInfo: The floating point information
6501 object was converted from a dict to a specialized structseq object.
6502
Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Patch #1816: Added sys.flags structseq. It exposes the status of
6504 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006505
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- Objects/structseq.c: Implemented new structseq representation. The
6507 patch makes structseqs (e.g. the return value of os.stat) more
6508 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006509
Georg Brandl3ee81df2008-05-17 18:14:43 +00006510- Patch #1700288: added a type attribute cache that caches method
6511 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006512
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006513- Bug #1776: __import__() no longer accepts filenames on any platform.
6514 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006515
Georg Brandlaed6c662008-01-07 17:25:53 +00006516- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6517
Georg Brandl3ee81df2008-05-17 18:14:43 +00006518- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6519 envvar and sys.dont_write_bytecode attribute. All these can be set
6520 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006521
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- Improve some exception messages when Windows fails to load an
6523 extension module. Now we get for example '%1 is not a valid Win32
6524 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006525
Georg Brandl3ee81df2008-05-17 18:14:43 +00006526- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00006527
Georg Brandl3ee81df2008-05-17 18:14:43 +00006528- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6529 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006530
Christian Heimes0a8143f2007-12-18 23:22:54 +00006531- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532 and INF. float("nan"), float("inf") and float("-inf") now work on
6533 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006534
Georg Brandl3ee81df2008-05-17 18:14:43 +00006535- Compiler now generates simpler and faster code for dictionary
6536 literals. The oparg for BUILD_MAP now indicates an estimated
6537 dictionary size. There is a new opcode, STORE_MAP, for adding
6538 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006539
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- Issue #1620: New property decorator syntax was modifying the
6543 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006544
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545- Issue #1538: Avoid copying string in split/rsplit if the split char
6546 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006547
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006548- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006549 SystemError.
6550
Nick Coghlanef01d822007-12-03 12:55:17 +00006551- PEP 366: Allow explicit relative imports when executing modules
6552 inside packages with the -m switch via a new module level
6553 __package__ attribute.
6554
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555- Issue #1402: Fix a crash on exit, when another thread is still
6556 running, and if the deallocation of its frames somehow calls the
6557 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006558

6560
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00006561- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006562 attribute of an empty cell object.
6563
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564- Issue #1460: The utf-7 incremental decoder did not accept truncated
6565 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006566
Georg Brandl3ee81df2008-05-17 18:14:43 +00006567- Patch #1739468: Directories and zipfiles containing a __main__.py
6568 file can now be directly executed by passing their name to the
6569 interpreter. The directory/zipfile is automatically inserted as the
6570 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006571
Georg Brandl3ee81df2008-05-17 18:14:43 +00006572- Issue #1265: Fix a problem with sys.settrace, if the tracing
6573 function uses a generator expression when at the same time the
6574 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006575
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006576- sets and frozensets now have an isdisjoint() method.
6577
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006578- optimize the performance of builtin.sum().
6579
Neal Norwitz44f326e2007-10-05 05:29:17 +00006580- Fix warnings found by the new version of the Coverity checker.
6581
Georg Brandl21e99f42010-03-07 15:23:59 +00006582- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006583 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6584 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006585
Georg Brandl3ee81df2008-05-17 18:14:43 +00006586- Issue #1686386: Tuple's tp_repr did not take into account the
6587 possibility of having a self-referential tuple, which is possible
6588 from C code. Nor did object's tp_str consider that a type's tp_str
6589 could do something that could lead to an inifinite recursion.
6590 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6591 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006592
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Issue #1164: It was possible to trigger deadlock when using the
6594 'print' statement to write to a file since the GIL was not released
6595 as needed. Now PyObject_Print() does the right thing along with
6596 various tp_print implementations of the built-in types and those in
6597 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006598
Georg Brandl3ee81df2008-05-17 18:14:43 +00006599- Issue #1147: Exceptions were directly allowing string exceptions in
6600 their throw() method even though string exceptions no longer
6601 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Issue #1096: Prevent a segfault from getting the repr of a very
6604 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006605
Brett Cannon1e534b52007-09-07 04:18:30 +00006606- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607 PyObject_Call() never calling back out to Python code to trigger
6608 recursion depth updates/checks. Required the creation of a static
6609 RuntimeError instance in case normalizing an exception put the
6610 recursion check value past its limit. Fixes crashers
6611 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006612
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613- Patch #1031213: Decode source line in SyntaxErrors back to its
6614 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00006615
Georg Brandl7c3b50d2007-07-12 08:38:00 +00006616- Patch #1673759: add a missing overflow check when formatting floats
6617 with %G.
6618
Georg Brandl3ee81df2008-05-17 18:14:43 +00006619- Prevent expandtabs() on string and unicode objects from causing a
6620 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006621

Georg Brandla5ea6892007-06-01 11:33:33 +00006625
Neal Norwitz0ac60192007-05-27 04:08:54 +00006626- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627 __*__ attributes. (Some already existed, e.g., __doc__ and
6628 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006629
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006630- Add -3 option to the interpreter to warn about features that are
6631 deprecated and will be changed/removed in Python 3.0.
6632
Georg Brandl2134e752007-05-21 20:34:16 +00006633- Patch #1686487: you can now pass any mapping after '**' in function
6634 calls.
6635
Collin Winter62903052007-05-18 23:11:24 +00006636- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637 "except E as target:". This is to provide forwards compatibility
6638 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006639
Brett Cannon229cee22007-05-05 01:34:02 +00006640- Deprecate BaseException.message as per PEP 352.
6641
Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006643 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006644
Vinay Sajip8549ce32007-05-06 17:53:37 +00006645- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006646 setting a plain string, ie don't expand to single letter identifiers.
6647
Raymond Hettinger13936692007-04-11 18:40:58 +00006648- Request #1191699: Slices can now be pickled.
6649
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006650- Request #1193128: str.translate() now allows a None argument for
6651 translations that only remove characters without re-mapping the
6652 remaining characters.
6653
Georg Brandl5cb76c12007-03-21 09:00:39 +00006654- Patch #1682205: a TypeError while unpacking an iterable is no longer
6655 masked by a generic one with the message "unpack non-sequence".
6656
Neal Norwitzaa754b72007-03-21 06:39:48 +00006657- Remove unused file Python/fmod.c.
6658
Guido van Rossum143b5642007-03-23 04:58:42 +00006659- Bug #1683368: The object.__init__() and object.__new__() methods are
6660 now stricter in rejecting excess arguments. The only time when
6661 either allows excess arguments is when it is not overridden and the
6662 other one is. For backwards compatibility, when both are
6663 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006664 warning later). Also, type.__init__() insists on the same signature
6665 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006666
Georg Brandl3ee81df2008-05-17 18:14:43 +00006667- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6668 object to complex using its __complex__() method before falling back
6669 to the __float__() method. Therefore, the functions in the cmath
6670 module now can operate on objects that define a __complex__()
6671 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006672
Georg Brandl3ee81df2008-05-17 18:14:43 +00006673- Patch #1623563: allow __class__ assignment for classes with
6674 __slots__. The old and the new class are still required to have the
6675 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006676
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Patch #1642547: Fix an error/crash when encountering syntax errors
6678 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006680- Patch #1462488: Python no longer segfaults when
6681 ``object.__reduce_ex__()`` is called with an object that is faking
6682 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006683
Georg Brandl3ee81df2008-05-17 18:14:43 +00006684- Patch #1680015: Don't modify __slots__ tuple if it contains an
6685 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00006687- Patch #1444529: the builtin compile() now accepts keyword arguments.
6688
Georg Brandl7b9c5552007-03-12 14:30:05 +00006689- Bug #1678647: write a newline after printing an exception in any
6690 case, even when converting the value to a string failed.
6691
Georg Brandl871f1bc2007-03-12 13:17:36 +00006692- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006693 its argument, if it exists. If not, it will work like before. This
6694 allows customizing the output of dir() in the presence of a
6695 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006696
Collin Winter276887b2007-03-12 16:11:39 +00006697- Patch #922167: Python no longer segfaults when faced with infinitely
6698 self-recursive reload() calls (as reported by bug #742342).
6699
Georg Brandl3ee81df2008-05-17 18:14:43 +00006700- Patch #1675981: remove unreachable code from ``type.__new__()``
6701 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006702
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703- Patch #1491866: change the complex() constructor to allow
6704 parthensized forms. This means complex(repr(x)) now works instead of
6705 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006706
Georg Brandlaa2321b2007-03-07 00:40:28 +00006707- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006708 makes the filenames the warning module prints much more sensible

7217
Facundo Batistad918a652007-04-24 13:54:38 +00007218- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007219 the client's request was successfully received, understood, and
7220 accepted. Now in these cases no error is raised in urllib (issue
7221 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007222

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007229- Added a timeout parameter to the constructor of other protocols
7230 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7231 work started with create_connection() and timeout in httplib, and
7232 closes patch #723312.
7233
Vinay Sajip8549ce32007-05-06 17:53:37 +00007234- Patch #1676823: Added create_connection() to socket.py, which may be
7235 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007236 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007237
Martin v. Löwis0af33882007-03-23 13:27:15 +00007238- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7258
Georg Brandlf66b6032007-03-14 08:27:52 +00007259- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007260 AttributeError instead of an IOError when the server's response
7261 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007262
Georg Brandl3ee81df2008-05-17 18:14:43 +00007263- Patch #957650: "%var%" environment variable references are now
7264 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007266
Georg Brandl3ee81df2008-05-17 18:14:43 +00007267- Patch #1429539: pdb now correctly initializes the __main__ module
7268 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007269 correctly now.
7270
Georg Brandlbad6f192007-03-13 21:32:56 +00007271- The nonobvious commands.getstatus() function is now deprecated.

7277
Georg Brandl3ee81df2008-05-17 18:14:43 +00007278- Patch #1530482: add pydoc.render_doc() which returns the
7279 documentation for a thing instead of paging it to stdout, which
7280 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007281
Georg Brandl3ee81df2008-05-17 18:14:43 +00007282- Patch #1533909: the timeit module now accepts callables in addition

7288 parameter which can be set to False to prevent the default
7289 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007290
Georg Brandl9e6b4702007-03-13 18:15:41 +00007291- Patch #1581073: add a flag to textwrap that prevents the dropping of
7292 whitespace while wrapping.
7293
Georg Brandl92a6bae2007-03-13 17:43:32 +00007294- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007295 are set for invalid interpolation sequences that would lead to
7296 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007297

7310
Georg Brandl94fe3f52007-03-13 09:32:11 +00007311- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007312 field names in its exception message if you try to write a record
7313 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007331

7339 returned string up to the first NUL character.
7340

7350
Georg Brandl3ee81df2008-05-17 18:14:43 +00007351- unittest now verifies more of its assumptions. In particular,
7352 TestCase and TestSuite subclasses (not instances) are no longer
7353 accepted in TestSuite.addTest(). This should cause no
7354 incompatibility since it never made sense with ordinary subclasses
7355 -- the failure just occurred later, with a more cumbersome
7356 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007357

7365 given a unicode argument and os.listdir() returns unicode filenames.
7366
Georg Brandl3ee81df2008-05-17 18:14:43 +00007367- Patch #1673619: setup.py identifies extension modules it doesn't

7369 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007745 time so that opening a database previously created with the DB_DUP
7746 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7747 opens. Specifically: dictionary assignment to a DB object will
7748 replace all values for a given key when the database allows
7749 duplicate values. DB users should use DB.put(k, v) when they want
7750 to store duplicates; not DB[k] = v.

7757 characters with ASCII value less than 32. Also, it correctly quotes
7758 dots only if they occur on a single line, as opposed to the previous
7759 behavior of quoting dots if they are the second character of any
7760 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007761
