Ned Deily18fae3f2013-01-31 01:24:55 -08001049- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1050 In particular, fix extension module build failures when trying to use
1051 32-bit-only installer Pythons on systems with Xcode 4 (currently
1052 OS X 10.8, 10.7, and optionally 10.6).
1053 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1054 * Since Xcode 4 removes ppc support, extension module builds now
1055 check for ppc compiler support and by default remove ppc and
1056 ppc64 archs when they are not available.
1057 * Extension module builds now revert to using system installed
1058 headers and libs (/usr and /System/Library) if the SDK used
1059 to build the interpreter is not installed or has moved.
1060 * Try to avoid building extension modules with deprecated
1061 and problematic Apple llvm-gcc compiler. If original compiler
1062 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001486- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001487 has left two versions of customize_compiler, the original in
1488 distutils.sysconfig and another copy in distutils.ccompiler, with some
1489 parts of distutils calling one and others using the other.
1490 Complete the revert back to only having one in distutils.sysconfig as
1491 is the case in 3.x.
1492
Ned Deily0d0ea482012-02-10 12:59:06 +01001493- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1494 Distutils-based packages with C extension modules may fail because
1495 Apple has removed gcc-4.2, the version used to build python.org
1496 64-bit/32-bit Pythons. If the user does not explicitly override
1497 the default C compiler by setting the CC environment variable,
1498 Distutils will now attempt to compile extension modules with clang
1499 if gcc-4.2 is required but not found. Also as a convenience, if
1500 the user does explicitly set CC, substitute its value as the default
1501 compiler in the Distutils LDSHARED configuration variable for OS X.
1502 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1503 SDK, neither of which are available in Xcode 4. This change does not
1504 attempt to override settings to support their use with Xcode 4.)

1760 still possible to globally override the default by setting
1761 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1762 greater or equal to the default value, the value with which the interpreter
1763 was built.

2777 This prevents user-created self-referencing ordered dictionaries from
2778 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003240- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3241 start byte and the continuation byte(s) are now considered invalid, instead
3242 of the number of bytes specified by the start byte.
3243 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3244 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3245 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3246 Previous versions returned a single u'\ufffd'.
3247
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003248- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003249 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3250 arises from the "Overriding __eq__ blocks inheritance ..." warning
3251 when turned into an exception: in this case the exception simply
3252 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003253
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003254- Issue #8748: Fix two issues with comparisons between complex and integer
3255 objects. (1) The comparison could incorrectly return True in some cases
3256 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3257 (2) The comparison raised an OverflowError for large integers, leading
3258 to unpredictable exceptions when combining integers and complex objects
3259 in sets or dicts.
3260
Mark Dickinson81336372010-05-30 12:12:25 +00003261- Issue #5211: Implicit coercion for the complex type is now completely
3262 removed. (Coercion for arithmetic operations was already removed in 2.7
3263 alpha 4, but coercion for rich comparisons was accidentally left in.)
3264
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003265- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3266 and error handler, instead of writing to the C stderr file in utf-8
3267
Georg Brandlfee0f442010-05-22 21:26:21 +00003268- Issue #7902: When using explicit relative import syntax, don't try implicit

3627
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003628- Issue #8329: Don't return the same lists from select.select when no fds are
3629 changed.
3630
Georg Brandlfee0f442010-05-22 21:26:21 +00003631- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003632 on 64-bit machines. The shift count for either left or right shift is
3633 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00003641- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3642 with a non-empty format string. This is an effort to future-proof user
3643 code. If a derived class does not currently implement __format__ but later
3644 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003645 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003646 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003701- Issue #2531: Comparison operations between floats and Decimal instances now
3702 return a result based on the numeric values of the operands; previously they

Georg Brandlba83f822010-03-14 09:50:54 +00004017- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00004018 thread could raise an incorrect RuntimeError about not holding the import
4019 lock. The import lock is now reinitialized after fork.

4032 common TestCase for some tests: test_genericpath.CommonTest.
4033
Georg Brandlba83f822010-03-14 09:50:54 +00004034- Print platform information when running the whole test suite, or using the
4035 ``--verbose`` flag.

Georg Brandlba83f822010-03-14 09:50:54 +00004040- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004041 is run with the -OO flag. Tests requiring docstrings are skipped.
4042
Georg Brandlba83f822010-03-14 09:50:54 +00004043- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4044 now also used by regrtest to run all the tests in a temporary directory. The
4045 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4046 Xicluna who helped with the patch.

4063 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004064 library would return a bogus result; on Solaris, it was possible to crash the
4065 interpreter. Patch by Stefan Krah.

4076 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00004077
Georg Brandlba83f822010-03-14 09:50:54 +00004078- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4079 and add the additional members returned in an OSVERSIONINFOEX structure. The
4080 new members are service_pack_major, service_pack_minor, suite_mask, and
4081 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00004082
Georg Brandlba83f822010-03-14 09:50:54 +00004083- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4084 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4085 returning NULL. The macro now returns a statically allocated empty string
4086 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00004087
Antoine Pitrou64672132010-01-13 07:55:48 +00004088- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00004095 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4096 strings,
4097 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4098 numeric strings corresponding to subnormal values,
4099 (3) a memory leak for some values large enough to cause overflow, and
4100 (4) a number of flaws that could lead to incorrectly rounded results.
4101

4103 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00004104

4116
R. David Murray63e4fd72010-02-10 22:42:04 +00004117- Issue #7835: shelve should no longer produce mysterious warnings during
4118 interpreter shutdown.
4119
Georg Brandlba83f822010-03-14 09:50:54 +00004120- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4121 XML processing instructions and comments. These raw characters are allowed
4122 by the XML specification, and are necessary when outputting e.g. PHP code in
4123 a processing instruction. Patch by Neil Muller.

Georg Brandlba83f822010-03-14 09:50:54 +00004129- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00004130
Antoine Pitroud840e512010-02-04 20:20:18 +00004131- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004132 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004133 Also, raise ValueError rather than TypeError when an unknown TIPC address
4134 type is specified. Patch by Brian Curtin.
4135
Vinay Sajip28c382f2010-02-04 18:48:53 +00004136- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004138- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004139 file position when calling `truncate()`. It would previously change the file
4140 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004141 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4142
Georg Brandlba83f822010-03-14 09:50:54 +00004143- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4144 class used to represent files stored inside an archive. The new
4145 implementation is significantly faster and can be wrapped in a
4146 ``io.BufferedReader`` object for more speedups. It also solves an issue
4147 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4148 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004157
Georg Brandlba83f822010-03-14 09:50:54 +00004158- Issue #7748: Since unicode values are supported for some metadata options in
4159 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4160 encoded string for them. This ensures that the upload and register commands
4161 send the correct values to PyPI without any error.

4237
Georg Brandlba83f822010-03-14 09:50:54 +00004238- The ``__complex__()`` method is now looked up on the class of instances to
4239 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004240
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004241- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4243
Mark Dickinson1b34d252010-01-01 17:27:30 +00004244- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004245 DeprecationWarning when passed a float argument where an integer was expected.
4246 These functions and methods now raise TypeError instead. The majority of the
4247 effects of this change are in the extension modules, but some core functions
4248 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4249 and many unicode/str methods.

4263 of integers: the result of a/b is now correctly rounded for ints a and b (at
4264 least on IEEE 754 platforms), and in particular does not depend on the
4265 internal representation of a long.

4273
Georg Brandlba83f822010-03-14 09:50:54 +00004274 These executables now work properly with the arch(1) command: ``arch -ppc
4275 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004432- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4433 decimal string that's guaranteed to round back to x under correct rounding
4434 (with round-half-to-even rounding mode). Previously it gave a string based on
4435 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4436 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4437 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004439- Issue #7117: On almost all platforms: float-to-string and string-to-float
4440 conversions within Python are now correctly rounded. Places these conversions
4441 occur include: str for floats and complex numbers; the float and complex
4442 constructors; old-style and new-style numeric formatting; serialization and
4443 deserialization of floats and complex numbers using marshal, pickle and json;
4444 parsing of float and imaginary literals in Python code; Decimal-to-float
4445 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004446
Georg Brandlba83f822010-03-14 09:50:54 +00004447 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4448 providing correctly-rounded strtod and dtoa C functions. This code is
4449 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4450 the C compiler. There may be a small number of platforms on which correct
4451 operation of this code cannot be guaranteed, so the code is not used: notably,
4452 this applies to platforms where the C double format is not IEEE 754 binary64,
4453 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4454 and Python's configure script is unable to determine how to change the FPU
4455 precision. On these platforms conversions use the platform strtod and dtoa,
4456 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004458- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4459 uses the correctly-rounded string <-> float conversions described above (when
4460 available), and so produces correctly rounded results that will display nicely
4461 under the float repr. There are two related small changes: (1) round now
4462 accepts any class with an ``__index__()`` method for its second argument (but
4463 no longer accepts floats for the second argument), and (2) an excessively
4464 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4465 raises an exception.

4880 gives improved memory leak detection when running under Valgrind, while taking

6049 struct.error. Previously an x with an __int__ method could be packed by
6050 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6051 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6052 neither __int__ nor __long__, TypeError used to be raised (with a
6053 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6054 struct.error in other cases.

6057 argument with an __int__ method can be packed, but use of this feature
6058 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00006107 leak-chasing test runs give sensible results. The previous method of reaping
6108 threads could return successfully while some Thread objects were still

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006251- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6252 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6253 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6254 ``printf`` function, whereas PyString_FromFormat has an independent
6255 implementation and uses "%zd" on all platforms for size_t values.
6256 This makes a difference on win64, where ``printf`` needs "%Id" to display
6257 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006273 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006274 was correctly parsed but parsing of subsequent arguments failed.
6275
Vinay Sajip35e3b032008-09-01 14:33:59 +00006276- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006277 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6278 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6279 when given a tuple of classes as second argument, were looking up
6280 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6281 type object.
6282
Neal Norwitz18aa3882008-08-24 05:04:52 +00006283- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00006291- Silenced another compiler warning about a used but not defined
6292 function 'stringlib_contains_obj'.
6293
Benjamin Peterson712ee922008-08-24 18:10:20 +00006294- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6295 ``__delslice__``.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006352 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6353 for catch_warnings() also led to an improvement in the raising of a
6354 DeprecationWarning related to warnings.warn_explicit().
6355
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006356- The deprecation warnings for the old camelCase threading API were removed.

6378
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006379- Issue #2975: When compiling several extension modules with Visual Studio 2008
6380 from the same python interpreter, some environment variables would grow
6381 without limit.
6382
Benjamin Peterson37346b22008-08-23 20:27:43 +00006383- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006420What's New in Python 2.6 beta 3?
6421================================
6422
Barry Warsaw07a4a382008-08-21 01:15:08 +00006423*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006424
6425Core and Builtins
6426-----------------
6427
Guido van Rossumf8402962008-08-20 15:01:50 +00006428- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6429 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6430 extensions do not automatically benefit from the class attribute
6431 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6432 to their tp_flags field if they care. This is a backwards
6433 compatibility feature; in 3.0, all types will use the cache by
6434 default.
6435
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006436- Keyword arguments can now follow starred arguments. (``f(a, *args,
6437 keyword=23)`` is now valid syntax.)
6438
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006439- ctypes function pointers that are COM methods have a boolean True
6440 value again.
6441
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006442- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6443 by denying s# to parse objects that have a releasebuffer procedure,
6444 and introducing s*.
6445
Georg Brandl1e13ea92008-08-11 09:07:59 +00006446- Issue #3537: Fix an assertion failure when an empty but presized dict
6447 object was stored in the freelist.
6448
Mark Dickinsonb6467572008-08-04 21:30:09 +00006449- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6450 ValueError consistently across platforms.
6451
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006452- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6453 (64bit Unix, for example), unichr() would truncate its argument and return
6454 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6455
Neal Norwitze7d8be82008-07-31 17:17:14 +00006456- Apply security patches from Apple.
6457
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006458- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6459 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6460
Antoine Pitrou92f82162008-07-25 22:22:08 +00006461- Issue #1819: function calls with several named parameters are now on
6462 average 35% faster (as measured by pybench).
6463
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006464- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6465 the python debugger steps into a class statement: the free variables (local
6466 variables defined in an outer scope) would be deleted from the outer scope.
6467
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006468- Issue #2620: Overflow checking when allocating or reallocating memory
6469 was not always being done properly in some python types and extension
6470 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6471 all been updated to perform better checks and places in the code that
6472 would previously leak memory on the error path when such an allocation
6473 failed have been fixed.

6476-------
6477
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006478- Issue #3612: Added some missing basic types in ctypes.wintypes.
6479
Benjamin Petersone977ad42008-08-20 01:42:01 +00006480- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6481 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6482
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006483- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6484 version reported by these tools does not necessarily follow the python
6485 version numbering scheme, so the module is less strict when parsing it.
6486
Nick Coghlanf70385a2008-08-18 12:42:46 +00006487- Issue #2235: Added Py3k warnings for types which will become unhashable
6488 under the stricter __hash__ inheritance rules in 3.0. Several types
6489 which did not meet the rules for hash invariants and were already
6490 unhashable in 3.0 have now been explicitly flagged as unhashable in
6491 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6492 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6493
Brett Cannon88f801d2008-08-18 00:46:22 +00006494- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6495 imported into the module but exposed as part of the module's API.
6496
Brett Cannon7b96f072008-08-18 00:41:11 +00006497- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6498
Brett Cannon46225e72008-08-18 00:36:52 +00006499- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006501- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6502
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006503- Issue #3575: Incremental decoder's decode function now takes bytearray
6504 by using 's*' instead of 't#'.
6505
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006506- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006507 fails unicode conversion on 2nd parameter. (windows only)
6508
Georg Brandl222e2082010-08-01 22:27:39 +00006509- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006510 in a redirect.
6511
Brett Cannonabe423e2008-08-16 21:47:07 +00006512- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006513 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006514
Facundo Batistaeb90b782008-08-16 14:44:07 +00006515- Issue #2776: fixed small issue when handling an URL with double slash
6516 after a 302 response in the case of not going through a proxy.
6517
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006518- Issue #2676: in the email package, content-type parsing was hanging on
6519 pathological input because of quadratic or exponential behaviour of a
6520 regular expression.
6521
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006522- Issue #3476: binary buffered reading through the new "io" library is now
6523 thread-safe.
6524
Brett Cannonbf3157b2008-08-14 05:00:03 +00006525- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6526 since mimetools itself is deprecated. Because modules are cached, all
6527 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6528
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006529- Issue #3134: shutil referenced undefined WindowsError symbol.
6530
Robert Schuppenies14646332008-08-10 11:01:53 +00006531- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6532 menu entries were not deleted.
6533
Brett Cannon83e81842008-08-09 23:30:55 +00006534- Copied the implementation of reduce() to _functools.reduce() to have a
6535 version that did not raise a DeprecationWarning under -3.
6536
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006537- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6538 a MemoryError rather than silently stop the iteration.
6539
Guido van Rossum59ce9012008-08-09 14:55:34 +00006540- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6541 to _sre.compile() will now be rejected. This should not affect anybody
6542 since the re.compile() function never generates invalid re-bytecode.
6543
Skip Montanaroa032bf42008-08-08 22:52:51 +00006544- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6545 upon first access it can be automatically initialized from the csv file if
6546 it wasn't initialized during instantiation.
6547
Brett Cannon3aa2a492008-08-06 22:28:09 +00006548- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6549 the reload() built-in has been removed.
6550
Brett Cannon7e30b672008-08-04 21:52:25 +00006551- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006552 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006553 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

6620-----------------
6621
Georg Brandl3e483f62008-07-16 22:57:41 +00006622- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6623 its methods now allow for items objects that can be converted to
6624 an integer using operator.index().
6625
Mark Dickinson64b7e502008-07-16 09:40:03 +00006626- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6627 produced a ValueError instead of giving the correct float.
6628
Eric Smitha5fa5a22008-07-16 00:11:49 +00006629- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6630 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6631
Mark Dickinson7103aa42008-07-15 19:08:33 +00006632- Issue #3008: the float type has a new instance method 'float.hex'
6633 and a new class method 'float.fromhex' to convert floating-point
6634 numbers to and from hexadecimal strings, respectively.
6635
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006636- Issue #2235: __hash__ is once again inherited by default. To allow
6637 collections.Hashable to remain meaningful in the presence of the
6638 default hash implementation (object.__hash__), it is now possible
6639 to explicit block inheritance of hash by setting __hash__=None at
6640 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6641 level.
6642
Nick Coghlanb028f502008-07-13 14:52:36 +00006643- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6644 the parent module cannot be found while performing an absolute import.
6645 This means that an incorrectly defined __package__ attribute will
6646 now only prevent relative imports in that module rather than causing
6647 all imports from that module to fail.
6648
Nick Coghlan14ff9942008-07-08 14:21:42 +00006649- Issue #2517: Allow unicode messages in Exceptions again by correctly

6659 another thread's dictionary.
6660
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006661- Issue #3004: Minor change to slice.indices(): the start and stop
6662 arguments are now treated identically, making the behaviour easier
6663 to describe and understand. For example, slice(None, -10,
6664 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6665 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6666 10, -1).
6667
Georg Brandl278fc502008-07-19 12:46:12 +00006668- Issue #3219: Calling a function with repeated keyword arguments,
6669 f(a=2, a=23), would not cause a syntax error. This was a regression
6670 from 2.4 caused by the switch to the new compiler.

6673 other freelists. Changes their CompactFreeList apis into

6681 error when they failed.
6682
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006683- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006708- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6709 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006710 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006711 content-length. The problem had been corrected in the 2.4 branch, but never
6712 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006727- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6728 handling is now the same as that of other special attributes like __name__).
6729
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006730- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7122 This is controlled by the configure argument ``--with-universal-archs``:
7123
7124 - ``--with-universal-archs=all``: install 4-way universal
7125
7126 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7127
7128 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7129
7130 This option should be used in combination with ``--enable-universalsdk=``.
7131
7132 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7140- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007141
7142- The PyString functions have been renamed to PyBytes. A batch of
7143 defines were added so that the linker still sees the original
7144 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007182- Issue #1631171: Re-implement the 'warnings' module in C (the
7183 original Python code has been kept as backup). This will allow for
7184 using the 'warning's machinery in such places as the parser where
7185 use of pure Python code is not possible. Both the ``showarning()``
7186 and ``formatwarning()`` gain an optional 'line' argument which is
7187 not called by default for backwards-compatibility reasons. Setting
7188 ``warnings.showwarning()`` to an implementation that lacks support
7189 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007231- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007232 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007252- Issue #2550: The approach used by client/server code for obtaining
7253 ports to listen on in network-oriented tests has been refined in an
7254 effort to facilitate running multiple instances of the entire
7255 regression test suite in parallel without issue.
7256 test_support.bind_port() has been fixed such that it will always
7257 return a unique port -- which wasn't always the case with the
7258 previous implementation, especially if socket options had been set
7259 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7260 new implementation of bind_port() will actually raise an exception
7261 if it is passed an AF_INET/SOCK_STREAM socket with either the
7262 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7263 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7264 the socket it's been passed. This currently only applies to
7265 Windows. This option prevents any other sockets from binding to the
7266 host/port we've bound to, thus removing the possibility of the
7267 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7268 when a second SOCK_STREAM socket binds and accepts to a host/port
7269 that's already been bound by another socket. The optional preferred
7270 port parameter to bind_port() has been removed. Under no
7271 circumstances should tests be hard coding ports!
7272
7273 test_support.find_unused_port() has also been introduced, which will
7274 pass a temporary socket object to bind_port() in order to obtain an
7275 unused port. The temporary socket object is then closed and
7276 deleted, and the port is returned. This method should only be used
7277 for obtaining an unused port in order to pass to an external program
7278 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7279 a parameter to a server-oriented class that doesn't give you direct
7280 access to the underlying socket used.
7281
7282 Finally, test_support.HOST has been introduced, which should be used
7283 for the host argument of any relevant socket calls (i.e. bind and
7284 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007285
7286 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007287 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007288 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7289 test_asynchat and test_socket_ssl.
7290
Georg Brandl3ee81df2008-05-17 18:14:43 +00007291 It is now possible for multiple instances of the regression test
7292 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007571- Added the future_builtins module, which contains hex() and oct().
7572 These are the PEP 3127 version of these functions, designed to be
7573 compatible with the hex() and oct() builtins from Python 3.0. They
7574 differ slightly in their output formats from the existing, unchanged
7575 Python 2.6 builtins. The expected usage of the future_builtins
7576 module is:
7577 from future_builtins import hex, oct
7578
Eric Smith7ef40bf2008-02-20 23:34:22 +00007579- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7580 exponents for exponents with absolute value < 100. Follows C99
7581 standard. This is a change on Windows, which would use 3 digits.
7582 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7583 so that any alterations it does to the resulting string will be
7584 available in stringlib/formatter.h (for float.__format__).
7585
Eric Smith5a3c1352008-02-19 13:21:56 +00007586- Implemented PEP 3101, Advanced String Formatting. This adds a new
7587 builtin format(); a format() method for str and unicode; a
7588 __format__() method to object, str, unicode, int, long, float, and
7589 datetime; the class string.Formatter; and the C API
7590 PyObject_Format().
7591
Georg Brandl3ee81df2008-05-17 18:14:43 +00007592- Fixed several potential crashes, all caused by specially crafted
7593 __del__ methods exploiting objects in temporarily inconsistent
7594 state.

7605 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007606
Georg Brandl3ee81df2008-05-17 18:14:43 +00007607- Issue #2045: Fix an infinite recursion triggered when printing a
7608 subclass of collections.defaultdict, if its default_factory is set
7609 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007610
Christian Heimesf75dbef2008-02-08 00:11:31 +00007611- Fixed a minor memory leak in dictobject.c. The content of the free

7620
Georg Brandl3ee81df2008-05-17 18:14:43 +00007621- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7622 calls. Python expected the return type int but the fork familie
7623 returns pi_t.

7638 the same object as the func_code attribute of the function that
7639 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007640
Georg Brandl3ee81df2008-05-17 18:14:43 +00007641- Issue #1920: "while 0" statements were completely removed by the
7642 compiler, even in the presence of an "else" clause, which is
7643 supposed to be run when the condition is false. Now the compiler
7644 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007645
Guido van Rossumeead05f2008-01-24 18:21:02 +00007646- A few crashers fixed: weakref_in_del.py (issue #1377858);
7647 loosing_dict_ref.py (issue #1303614, test67.py);
7648 borrowed_ref_[34].py (not in tracker).
7649
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007650- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007651 suppressed while an extension is loaded by calling SetErrorMode in
7652 dynload_win.c. The error is still reported properly.
7653
Georg Brandl3ee81df2008-05-17 18:14:43 +00007654- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007655 several extension methods and modules do not work without unicode
7656 support.
7657
Georg Brandl26543b12008-01-21 18:36:51 +00007658- Issue #1882: when compiling code from a string, encoding cookies in the
7659 second line of code were not always recognized correctly.
7660
Georg Brandl14404b62008-01-19 19:27:05 +00007661- Issue #1679: "0x" was taken as a valid integer literal.
7662
Georg Brandl6caad7d2008-01-26 14:19:22 +00007663- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007664 added.
7665
Christian Heimesc94e2b52008-01-14 04:13:37 +00007666- sys.float_info / PyFloat_GetInfo: The floating point information
7667 object was converted from a dict to a specialized structseq object.
7668
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669- Patch #1816: Added sys.flags structseq. It exposes the status of
7670 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007671
Georg Brandl3ee81df2008-05-17 18:14:43 +00007672- Objects/structseq.c: Implemented new structseq representation. The
7673 patch makes structseqs (e.g. the return value of os.stat) more
7674 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007675
Georg Brandl3ee81df2008-05-17 18:14:43 +00007676- Patch #1700288: added a type attribute cache that caches method
7677 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007678
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007679- Bug #1776: __import__() no longer accepts filenames on any platform.
7680 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007681
Georg Brandlaed6c662008-01-07 17:25:53 +00007682- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7683
Georg Brandl3ee81df2008-05-17 18:14:43 +00007684- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7685 envvar and sys.dont_write_bytecode attribute. All these can be set
7686 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007687
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- Improve some exception messages when Windows fails to load an
7689 extension module. Now we get for example '%1 is not a valid Win32
7690 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007691
Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00007693
Georg Brandl3ee81df2008-05-17 18:14:43 +00007694- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7695 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007696
Christian Heimes0a8143f2007-12-18 23:22:54 +00007697- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007698 and INF. float("nan"), float("inf") and float("-inf") now work on
7699 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007700
Georg Brandl3ee81df2008-05-17 18:14:43 +00007701- Compiler now generates simpler and faster code for dictionary
7702 literals. The oparg for BUILD_MAP now indicates an estimated
7703 dictionary size. There is a new opcode, STORE_MAP, for adding
7704 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00007707
Georg Brandl3ee81df2008-05-17 18:14:43 +00007708- Issue #1620: New property decorator syntax was modifying the
7709 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007710
Georg Brandl3ee81df2008-05-17 18:14:43 +00007711- Issue #1538: Avoid copying string in split/rsplit if the split char
7712 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007713
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007714- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007715 SystemError.
7716
Nick Coghlanef01d822007-12-03 12:55:17 +00007717- PEP 366: Allow explicit relative imports when executing modules
7718 inside packages with the -m switch via a new module level
7719 __package__ attribute.
7720
Georg Brandl3ee81df2008-05-17 18:14:43 +00007721- Issue #1402: Fix a crash on exit, when another thread is still
7722 running, and if the deallocation of its frames somehow calls the
7723 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007724

7726
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00007727- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007728 attribute of an empty cell object.
7729
Georg Brandl3ee81df2008-05-17 18:14:43 +00007730- Issue #1460: The utf-7 incremental decoder did not accept truncated
7731 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007732
Georg Brandl3ee81df2008-05-17 18:14:43 +00007733- Patch #1739468: Directories and zipfiles containing a __main__.py
7734 file can now be directly executed by passing their name to the
7735 interpreter. The directory/zipfile is automatically inserted as the
7736 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007737
Georg Brandl3ee81df2008-05-17 18:14:43 +00007738- Issue #1265: Fix a problem with sys.settrace, if the tracing
7739 function uses a generator expression when at the same time the
7740 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007741
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007742- sets and frozensets now have an isdisjoint() method.
7743
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007744- optimize the performance of builtin.sum().
7745
Neal Norwitz44f326e2007-10-05 05:29:17 +00007746- Fix warnings found by the new version of the Coverity checker.
7747
Georg Brandl21e99f42010-03-07 15:23:59 +00007748- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007749 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7750 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007751
Georg Brandl3ee81df2008-05-17 18:14:43 +00007752- Issue #1686386: Tuple's tp_repr did not take into account the
7753 possibility of having a self-referential tuple, which is possible
7754 from C code. Nor did object's tp_str consider that a type's tp_str
7755 could do something that could lead to an inifinite recursion.
7756 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7757 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007758
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- Issue #1164: It was possible to trigger deadlock when using the
7760 'print' statement to write to a file since the GIL was not released
7761 as needed. Now PyObject_Print() does the right thing along with
7762 various tp_print implementations of the built-in types and those in
7763 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007764
Georg Brandl3ee81df2008-05-17 18:14:43 +00007765- Issue #1147: Exceptions were directly allowing string exceptions in
7766 their throw() method even though string exceptions no longer
7767 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007768
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769- Issue #1096: Prevent a segfault from getting the repr of a very
7770 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007771
Brett Cannon1e534b52007-09-07 04:18:30 +00007772- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773 PyObject_Call() never calling back out to Python code to trigger
7774 recursion depth updates/checks. Required the creation of a static
7775 RuntimeError instance in case normalizing an exception put the
7776 recursion check value past its limit. Fixes crashers
7777 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007778
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Patch #1031213: Decode source line in SyntaxErrors back to its
7780 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00007781
Georg Brandl7c3b50d2007-07-12 08:38:00 +00007782- Patch #1673759: add a missing overflow check when formatting floats
7783 with %G.
7784
Georg Brandl3ee81df2008-05-17 18:14:43 +00007785- Prevent expandtabs() on string and unicode objects from causing a
7786 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007787
Georg Brandl3ee81df2008-05-17 18:14:43 +00007788- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007790- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00007791
Neal Norwitz0ac60192007-05-27 04:08:54 +00007792- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007793 __*__ attributes. (Some already existed, e.g., __doc__ and
7794 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007795
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007796- Add -3 option to the interpreter to warn about features that are
7797 deprecated and will be changed/removed in Python 3.0.
7798
Georg Brandl2134e752007-05-21 20:34:16 +00007799- Patch #1686487: you can now pass any mapping after '**' in function
7800 calls.
7801
Collin Winter62903052007-05-18 23:11:24 +00007802- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007803 "except E as target:". This is to provide forwards compatibility
7804 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007805
Brett Cannon229cee22007-05-05 01:34:02 +00007806- Deprecate BaseException.message as per PEP 352.
7807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007809 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007810
Vinay Sajip8549ce32007-05-06 17:53:37 +00007811- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007812 setting a plain string, ie don't expand to single letter identifiers.
7813
Raymond Hettinger13936692007-04-11 18:40:58 +00007814- Request #1191699: Slices can now be pickled.
7815
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007816- Request #1193128: str.translate() now allows a None argument for
7817 translations that only remove characters without re-mapping the
7818 remaining characters.
7819
Georg Brandl5cb76c12007-03-21 09:00:39 +00007820- Patch #1682205: a TypeError while unpacking an iterable is no longer
7821 masked by a generic one with the message "unpack non-sequence".
7822
Neal Norwitzaa754b72007-03-21 06:39:48 +00007823- Remove unused file Python/fmod.c.
7824
Guido van Rossum143b5642007-03-23 04:58:42 +00007825- Bug #1683368: The object.__init__() and object.__new__() methods are
7826 now stricter in rejecting excess arguments. The only time when
7827 either allows excess arguments is when it is not overridden and the
7828 other one is. For backwards compatibility, when both are
7829 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007830 warning later). Also, type.__init__() insists on the same signature
7831 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007832
Georg Brandl3ee81df2008-05-17 18:14:43 +00007833- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7834 object to complex using its __complex__() method before falling back
7835 to the __float__() method. Therefore, the functions in the cmath
7836 module now can operate on objects that define a __complex__()
7837 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007838
Georg Brandl3ee81df2008-05-17 18:14:43 +00007839- Patch #1623563: allow __class__ assignment for classes with
7840 __slots__. The old and the new class are still required to have the
7841 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007842
Georg Brandl3ee81df2008-05-17 18:14:43 +00007843- Patch #1642547: Fix an error/crash when encountering syntax errors
7844 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007846- Patch #1462488: Python no longer segfaults when
7847 ``object.__reduce_ex__()`` is called with an object that is faking
7848 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007849
Georg Brandl3ee81df2008-05-17 18:14:43 +00007850- Patch #1680015: Don't modify __slots__ tuple if it contains an
7851 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00007852
Georg Brandl5240d742007-03-13 20:46:32 +00007853- Patch #1444529: the builtin compile() now accepts keyword arguments.
7854
Georg Brandl7b9c5552007-03-12 14:30:05 +00007855- Bug #1678647: write a newline after printing an exception in any
7856 case, even when converting the value to a string failed.
7857
Georg Brandl871f1bc2007-03-12 13:17:36 +00007858- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007859 its argument, if it exists. If not, it will work like before. This
7860 allows customizing the output of dir() in the presence of a
7861 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007862
Collin Winter276887b2007-03-12 16:11:39 +00007863- Patch #922167: Python no longer segfaults when faced with infinitely
7864 self-recursive reload() calls (as reported by bug #742342).
7865
Georg Brandl3ee81df2008-05-17 18:14:43 +00007866- Patch #1675981: remove unreachable code from ``type.__new__()``
7867 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007868
Georg Brandl3ee81df2008-05-17 18:14:43 +00007869- Patch #1491866: change the complex() constructor to allow
7870 parthensized forms. This means complex(repr(x)) now works instead of
7871 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007872
Georg Brandlaa2321b2007-03-07 00:40:28 +00007873- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874 makes the filenames the warning module prints much more sensible

8383
Facundo Batistad918a652007-04-24 13:54:38 +00008384- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008385 the client's request was successfully received, understood, and
8386 accepted. Now in these cases no error is raised in urllib (issue
8387 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008388

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008395- Added a timeout parameter to the constructor of other protocols
8396 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8397 work started with create_connection() and timeout in httplib, and
8398 closes patch #723312.
8399
Vinay Sajip8549ce32007-05-06 17:53:37 +00008400- Patch #1676823: Added create_connection() to socket.py, which may be
8401 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008402 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008403
Martin v. Löwis0af33882007-03-23 13:27:15 +00008404- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8424
Georg Brandlf66b6032007-03-14 08:27:52 +00008425- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008426 AttributeError instead of an IOError when the server's response
8427 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008428
Georg Brandl3ee81df2008-05-17 18:14:43 +00008429- Patch #957650: "%var%" environment variable references are now
8430 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008432
Georg Brandl3ee81df2008-05-17 18:14:43 +00008433- Patch #1429539: pdb now correctly initializes the __main__ module
8434 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008435 correctly now.
8436
Georg Brandlbad6f192007-03-13 21:32:56 +00008437- The nonobvious commands.getstatus() function is now deprecated.

8443
Georg Brandl3ee81df2008-05-17 18:14:43 +00008444- Patch #1530482: add pydoc.render_doc() which returns the
8445 documentation for a thing instead of paging it to stdout, which
8446 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008447
Georg Brandl3ee81df2008-05-17 18:14:43 +00008448- Patch #1533909: the timeit module now accepts callables in addition

8454 parameter which can be set to False to prevent the default
8455 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008456
Georg Brandl9e6b4702007-03-13 18:15:41 +00008457- Patch #1581073: add a flag to textwrap that prevents the dropping of
8458 whitespace while wrapping.
8459
Georg Brandl92a6bae2007-03-13 17:43:32 +00008460- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008461 are set for invalid interpolation sequences that would lead to
8462 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008463

8476
Georg Brandl94fe3f52007-03-13 09:32:11 +00008477- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008478 field names in its exception message if you try to write a record
8479 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008497

8505 returned string up to the first NUL character.
8506

8516
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517- unittest now verifies more of its assumptions. In particular,
8518 TestCase and TestSuite subclasses (not instances) are no longer
8519 accepted in TestSuite.addTest(). This should cause no
8520 incompatibility since it never made sense with ordinary subclasses
8521 -- the failure just occurred later, with a more cumbersome
8522 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008523

8531 given a unicode argument and os.listdir() returns unicode filenames.
8532
Georg Brandl3ee81df2008-05-17 18:14:43 +00008533- Patch #1673619: setup.py identifies extension modules it doesn't

8535 build.

8887 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8888 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008904- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008905 time so that opening a database previously created with the DB_DUP
8906 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8907 opens. Specifically: dictionary assignment to a DB object will
8908 replace all values for a given key when the database allows
8909 duplicate values. DB users should use DB.put(k, v) when they want
8910 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008911

8917 characters with ASCII value less than 32. Also, it correctly quotes
8918 dots only if they occur on a single line, as opposed to the previous
8919 behavior of quoting dots if they are the second character of any
8920 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008921
