307 accepted by ``time.mktime`` and ``time.strftime`` is still system
308 dependent, but ``time.mktime`` will now accept full range supported
309 by the OS. Conversion of 2-digit years to 4-digit is deprecated.

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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001221- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1222 start byte and the continuation byte(s) are now considered invalid, instead
1223 of the number of bytes specified by the start byte.
1224 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1225 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1226 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1227 Previous versions returned a single u'\ufffd'.
1228
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001229- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001230 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1231 arises from the "Overriding __eq__ blocks inheritance ..." warning
1232 when turned into an exception: in this case the exception simply
1233 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001234
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001235- Issue #8748: Fix two issues with comparisons between complex and integer
1236 objects. (1) The comparison could incorrectly return True in some cases
1237 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1238 (2) The comparison raised an OverflowError for large integers, leading
1239 to unpredictable exceptions when combining integers and complex objects
1240 in sets or dicts.
1241
Mark Dickinson81336372010-05-30 12:12:25 +00001242- Issue #5211: Implicit coercion for the complex type is now completely
1243 removed. (Coercion for arithmetic operations was already removed in 2.7
1244 alpha 4, but coercion for rich comparisons was accidentally left in.)
1245
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001246- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1247 and error handler, instead of writing to the C stderr file in utf-8
1248
Georg Brandlfee0f442010-05-22 21:26:21 +00001249- Issue #7902: When using explicit relative import syntax, don't try implicit

1608
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001609- Issue #8329: Don't return the same lists from select.select when no fds are
1610 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001622- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1623 with a non-empty format string. This is an effort to future-proof user
1624 code. If a derived class does not currently implement __format__ but later
1625 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001626 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001627 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001688 argument `-` which tells it to read files to compile from stdin. Each line is
1689 read on demand and the named file is compiled immediately. (Original patch by
1690 Piotr Ożarowski).

1700 Fractions instance now raise TypeError instead of returning True/False. This
1701 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1702 <=> complex, and complex <=> complex comparisons.

1811 the set of integer codes for which it was used differed between native packing
1812 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002059- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2060 and add the additional members returned in an OSVERSIONINFOEX structure. The
2061 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002064- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2065 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2066 returning NULL. The macro now returns a statically allocated empty string
2067 instead.

2077 strings,
2078 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2079 numeric strings corresponding to subnormal values,
2080 (3) a memory leak for some values large enough to cause overflow, and
2081 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002112- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002113 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002114 Also, raise ValueError rather than TypeError when an unknown TIPC address
2115 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002119- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002120 file position when calling `truncate()`. It would previously change the file
2121 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002122 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2123
Georg Brandlba83f822010-03-14 09:50:54 +00002124- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2125 class used to represent files stored inside an archive. The new
2126 implementation is significantly faster and can be wrapped in a
2127 ``io.BufferedReader`` object for more speedups. It also solves an issue
2128 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2129 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002139- Issue #7748: Since unicode values are supported for some metadata options in
2140 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2141 encoded string for them. This ensures that the upload and register commands
2142 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002219- The ``__complex__()`` method is now looked up on the class of instances to
2220 make it consistent with other special methods.

2224
Mark Dickinson1b34d252010-01-01 17:27:30 +00002225- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002226 DeprecationWarning when passed a float argument where an integer was expected.
2227 These functions and methods now raise TypeError instead. The majority of the
2228 effects of this change are in the extension modules, but some core functions
2229 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2230 and many unicode/str methods.

2244 of integers: the result of a/b is now correctly rounded for ints a and b (at
2245 least on IEEE 754 platforms), and in particular does not depend on the
2246 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00002255 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002413- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2414 decimal string that's guaranteed to round back to x under correct rounding
2415 (with round-half-to-even rounding mode). Previously it gave a string based on
2416 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2417 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2418 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002420- Issue #7117: On almost all platforms: float-to-string and string-to-float
2421 conversions within Python are now correctly rounded. Places these conversions
2422 occur include: str for floats and complex numbers; the float and complex
2423 constructors; old-style and new-style numeric formatting; serialization and
2424 deserialization of floats and complex numbers using marshal, pickle and json;
2425 parsing of float and imaginary literals in Python code; Decimal-to-float
2426 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002427
Georg Brandlba83f822010-03-14 09:50:54 +00002428 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2429 providing correctly-rounded strtod and dtoa C functions. This code is
2430 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2431 the C compiler. There may be a small number of platforms on which correct
2432 operation of this code cannot be guaranteed, so the code is not used: notably,
2433 this applies to platforms where the C double format is not IEEE 754 binary64,
2434 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2435 and Python's configure script is unable to determine how to change the FPU
2436 precision. On these platforms conversions use the platform strtod and dtoa,
2437 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002439- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2440 uses the correctly-rounded string <-> float conversions described above (when
2441 available), and so produces correctly rounded results that will display nicely
2442 under the float repr. There are two related small changes: (1) round now
2443 accepts any class with an ``__index__()`` method for its second argument (but
2444 no longer accepts floats for the second argument), and (2) an excessively
2445 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2446 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004011- Issue #6561: '\d' in a regex now matches only characters with Unicode category
4012 'Nd' (Number, Decimal Digit). Previously it also matched characters with
4013 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00004014
Georg Brandlba83f822010-03-14 09:50:54 +00004015- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
4016 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4017 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00004018
Georg Brandlba83f822010-03-14 09:50:54 +00004019- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the
4020 integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=',
4021 '<', '>'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004022
Georg Brandlba83f822010-03-14 09:50:54 +00004023 - Packing a float now always gives a Deprecation Warning. Previously it
4024 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004025
Georg Brandlba83f822010-03-14 09:50:54 +00004026 - If x is not an int, long or float, then packing x will always result in
4027 struct.error. Previously an x with an __int__ method could be packed by
4028 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4029 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4030 neither __int__ nor __long__, TypeError used to be raised (with a
4031 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4032 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004033
Georg Brandlba83f822010-03-14 09:50:54 +00004034 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4035 argument with an __int__ method can be packed, but use of this feature
4036 triggers a DeprecationWarning.

4044 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00004045 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00004069- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4070 in the Lib/test directory, which might be read-only for the user running the
4071 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00004072
Georg Brandlba83f822010-03-14 09:50:54 +00004073- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
4074 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00004075
Georg Brandlba83f822010-03-14 09:50:54 +00004076- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
4077 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00004078
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00004079- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00004081- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
4082 primitives such as Lock, RLock, Condition, Event and Semaphore.
4083
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004084- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00004085 leak-chasing test runs give sensible results. The previous method of reaping
4086 threads could return successfully while some Thread objects were still
4087 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004088
Georg Brandlba83f822010-03-14 09:50:54 +00004089- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
4090 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00004091
Antoine Pitrou58d2f262009-10-10 20:52:11 +00004092- Issue #7055: test___all__ now greedily detects all modules which have an
4093 __all__ attribute, rather than using a hardcoded and incomplete list.
4094
R. David Murray14dcd432009-10-14 13:58:07 +00004095- Issue #7058: Added save/restore for things like sys.argv and cwd to
4096 runtest_inner in regrtest, with warnings if the called test modifies them,
4097 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00004098
Mark Dickinson245d9152009-10-04 18:38:39 +00004099- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

4102 off the trailing 0 in the version number.
4103
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004104- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4105 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004106 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4107 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00004109- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4110 regression tests in parallel, shortening the total runtime.
4111
Georg Brandlba83f822010-03-14 09:50:54 +00004112- Issue #5354: New test support function import_fresh_module() makes it easy to
4113 import both normal and optimised versions of modules. test_heapq and
4114 test_warnings have been adjusted to use it, tests for other modules with both
4115 C and Python implementations in the stdlib can be adjusted to use it over
4116 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004124- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4125 should cause a test to be skipped are now done using import_module from test
4126 support, which does the conversion.

4228
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004229- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4230 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4231 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4232 ``printf`` function, whereas PyString_FromFormat has an independent
4233 implementation and uses "%zd" on all platforms for size_t values.
4234 This makes a difference on win64, where ``printf`` needs "%Id" to display
4235 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004237- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004250- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004251 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004252 was correctly parsed but parsing of subsequent arguments failed.
4253
Vinay Sajip35e3b032008-09-01 14:33:59 +00004254- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004255 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4256 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4257 when given a tuple of classes as second argument, were looking up
4258 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4259 type object.
4260
Neal Norwitz18aa3882008-08-24 05:04:52 +00004261- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004330 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4331 for catch_warnings() also led to an improvement in the raising of a
4332 DeprecationWarning related to warnings.warn_explicit().
4333
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004334- The deprecation warnings for the old camelCase threading API were removed.

4356
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004357- Issue #2975: When compiling several extension modules with Visual Studio 2008
4358 from the same python interpreter, some environment variables would grow
4359 without limit.
4360
Benjamin Peterson37346b22008-08-23 20:27:43 +00004361- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004398What's New in Python 2.6 beta 3?
4399================================
4400
Barry Warsaw07a4a382008-08-21 01:15:08 +00004401*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004402
4403Core and Builtins
4404-----------------
4405
Guido van Rossumf8402962008-08-20 15:01:50 +00004406- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4407 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4408 extensions do not automatically benefit from the class attribute
4409 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4410 to their tp_flags field if they care. This is a backwards
4411 compatibility feature; in 3.0, all types will use the cache by
4412 default.
4413
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004414- Keyword arguments can now follow starred arguments. (``f(a, *args,
4415 keyword=23)`` is now valid syntax.)
4416
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004417- ctypes function pointers that are COM methods have a boolean True
4418 value again.
4419
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004420- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4421 by denying s# to parse objects that have a releasebuffer procedure,
4422 and introducing s*.
4423
Georg Brandl1e13ea92008-08-11 09:07:59 +00004424- Issue #3537: Fix an assertion failure when an empty but presized dict
4425 object was stored in the freelist.
4426
Mark Dickinsonb6467572008-08-04 21:30:09 +00004427- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4428 ValueError consistently across platforms.
4429
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004430- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4431 (64bit Unix, for example), unichr() would truncate its argument and return
4432 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4433
Neal Norwitze7d8be82008-07-31 17:17:14 +00004434- Apply security patches from Apple.
4435
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004436- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4437 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4438
Antoine Pitrou92f82162008-07-25 22:22:08 +00004439- Issue #1819: function calls with several named parameters are now on
4440 average 35% faster (as measured by pybench).
4441
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004442- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4443 the python debugger steps into a class statement: the free variables (local
4444 variables defined in an outer scope) would be deleted from the outer scope.
4445
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004446- Issue #2620: Overflow checking when allocating or reallocating memory
4447 was not always being done properly in some python types and extension
4448 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4449 all been updated to perform better checks and places in the code that
4450 would previously leak memory on the error path when such an allocation
4451 failed have been fixed.

4454-------
4455
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004456- Issue #3612: Added some missing basic types in ctypes.wintypes.
4457
Benjamin Petersone977ad42008-08-20 01:42:01 +00004458- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4459 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4460
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004461- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4462 version reported by these tools does not necessarily follow the python
4463 version numbering scheme, so the module is less strict when parsing it.
4464
Nick Coghlanf70385a2008-08-18 12:42:46 +00004465- Issue #2235: Added Py3k warnings for types which will become unhashable
4466 under the stricter __hash__ inheritance rules in 3.0. Several types
4467 which did not meet the rules for hash invariants and were already
4468 unhashable in 3.0 have now been explicitly flagged as unhashable in
4469 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4470 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4471
Brett Cannon88f801d2008-08-18 00:46:22 +00004472- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4473 imported into the module but exposed as part of the module's API.
4474
Brett Cannon7b96f072008-08-18 00:41:11 +00004475- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4476
Brett Cannon46225e72008-08-18 00:36:52 +00004477- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004479- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4480
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004481- Issue #3575: Incremental decoder's decode function now takes bytearray
4482 by using 's*' instead of 't#'.
4483
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004484- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004485 fails unicode conversion on 2nd parameter. (windows only)
4486
Georg Brandl222e2082010-08-01 22:27:39 +00004487- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004488 in a redirect.
4489
Brett Cannonabe423e2008-08-16 21:47:07 +00004490- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004491 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004492
Facundo Batistaeb90b782008-08-16 14:44:07 +00004493- Issue #2776: fixed small issue when handling an URL with double slash
4494 after a 302 response in the case of not going through a proxy.
4495
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004496- Issue #2676: in the email package, content-type parsing was hanging on
4497 pathological input because of quadratic or exponential behaviour of a
4498 regular expression.
4499
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004500- Issue #3476: binary buffered reading through the new "io" library is now
4501 thread-safe.
4502
Brett Cannonbf3157b2008-08-14 05:00:03 +00004503- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4504 since mimetools itself is deprecated. Because modules are cached, all
4505 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4506
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004507- Issue #3134: shutil referenced undefined WindowsError symbol.
4508
Robert Schuppenies14646332008-08-10 11:01:53 +00004509- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4510 menu entries were not deleted.
4511
Brett Cannon83e81842008-08-09 23:30:55 +00004512- Copied the implementation of reduce() to _functools.reduce() to have a
4513 version that did not raise a DeprecationWarning under -3.
4514
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004515- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4516 a MemoryError rather than silently stop the iteration.
4517
Guido van Rossum59ce9012008-08-09 14:55:34 +00004518- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4519 to _sre.compile() will now be rejected. This should not affect anybody
4520 since the re.compile() function never generates invalid re-bytecode.
4521
Skip Montanaroa032bf42008-08-08 22:52:51 +00004522- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4523 upon first access it can be automatically initialized from the csv file if
4524 it wasn't initialized during instantiation.
4525
Brett Cannon3aa2a492008-08-06 22:28:09 +00004526- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4527 the reload() built-in has been removed.
4528
Brett Cannon7e30b672008-08-04 21:52:25 +00004529- Changed code in the following modules/packages to remove warnings raised

4598-----------------
4599
Georg Brandl3e483f62008-07-16 22:57:41 +00004600- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4601 its methods now allow for items objects that can be converted to
4602 an integer using operator.index().
4603
Mark Dickinson64b7e502008-07-16 09:40:03 +00004604- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4605 produced a ValueError instead of giving the correct float.
4606
Eric Smitha5fa5a22008-07-16 00:11:49 +00004607- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4608 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4609
Mark Dickinson7103aa42008-07-15 19:08:33 +00004610- Issue #3008: the float type has a new instance method 'float.hex'
4611 and a new class method 'float.fromhex' to convert floating-point
4612 numbers to and from hexadecimal strings, respectively.
4613
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004614- Issue #2235: __hash__ is once again inherited by default. To allow
4615 collections.Hashable to remain meaningful in the presence of the
4616 default hash implementation (object.__hash__), it is now possible
4617 to explicit block inheritance of hash by setting __hash__=None at
4618 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4619 level.
4620
Nick Coghlanb028f502008-07-13 14:52:36 +00004621- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4622 the parent module cannot be found while performing an absolute import.
4623 This means that an incorrectly defined __package__ attribute will
4624 now only prevent relative imports in that module rather than causing
4625 all imports from that module to fail.
4626
Nick Coghlan14ff9942008-07-08 14:21:42 +00004627- Issue #2517: Allow unicode messages in Exceptions again by correctly

4637 another thread's dictionary.
4638
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004639- Issue #3004: Minor change to slice.indices(): the start and stop
4640 arguments are now treated identically, making the behaviour easier
4641 to describe and understand. For example, slice(None, -10,
4642 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4643 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4644 10, -1).
4645
Georg Brandl278fc502008-07-19 12:46:12 +00004646- Issue #3219: Calling a function with repeated keyword arguments,
4647 f(a=2, a=23), would not cause a syntax error. This was a regression
4648 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004686- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4687 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004688 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004689 content-length. The problem had been corrected in the 2.4 branch, but never
4690 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004705- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4706 handling is now the same as that of other special attributes like __name__).
4707
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004708- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005096- On MacOS X it is now possible to install the framework in 64-bit
5097 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005098 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005099
5100 This is controlled by the configure argument ``--with-universal-archs``:
5101
5102 - ``--with-universal-archs=all``: install 4-way universal
5103
5104 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5105
5106 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5107
5108 This option should be used in combination with ``--enable-universalsdk=``.
5109
5110 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5115
Georg Brandl74a1dea2008-05-28 11:21:39 +00005116- Add ``PyType_Modified()`` as a public API to clear the type cache.
5117
5118- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005119
5120- The PyString functions have been renamed to PyBytes. A batch of
5121 defines were added so that the linker still sees the original
5122 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Issue #1631171: Re-implement the 'warnings' module in C (the
5161 original Python code has been kept as backup). This will allow for
5162 using the 'warning's machinery in such places as the parser where
5163 use of pure Python code is not possible. Both the ``showarning()``
5164 and ``formatwarning()`` gain an optional 'line' argument which is
5165 not called by default for backwards-compatibility reasons. Setting
5166 ``warnings.showwarning()`` to an implementation that lacks support
5167 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005210 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Issue #2550: The approach used by client/server code for obtaining
5231 ports to listen on in network-oriented tests has been refined in an
5232 effort to facilitate running multiple instances of the entire
5233 regression test suite in parallel without issue.
5234 test_support.bind_port() has been fixed such that it will always
5235 return a unique port -- which wasn't always the case with the
5236 previous implementation, especially if socket options had been set
5237 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5238 new implementation of bind_port() will actually raise an exception
5239 if it is passed an AF_INET/SOCK_STREAM socket with either the
5240 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5241 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5242 the socket it's been passed. This currently only applies to
5243 Windows. This option prevents any other sockets from binding to the
5244 host/port we've bound to, thus removing the possibility of the
5245 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5246 when a second SOCK_STREAM socket binds and accepts to a host/port
5247 that's already been bound by another socket. The optional preferred
5248 port parameter to bind_port() has been removed. Under no
5249 circumstances should tests be hard coding ports!
5250
5251 test_support.find_unused_port() has also been introduced, which will
5252 pass a temporary socket object to bind_port() in order to obtain an
5253 unused port. The temporary socket object is then closed and
5254 deleted, and the port is returned. This method should only be used
5255 for obtaining an unused port in order to pass to an external program
5256 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5257 a parameter to a server-oriented class that doesn't give you direct
5258 access to the underlying socket used.
5259
5260 Finally, test_support.HOST has been introduced, which should be used
5261 for the host argument of any relevant socket calls (i.e. bind and
5262 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005263
5264 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005266 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5267 test_asynchat and test_socket_ssl.
5268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269 It is now possible for multiple instances of the regression test
5270 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005549- Added the future_builtins module, which contains hex() and oct().
5550 These are the PEP 3127 version of these functions, designed to be
5551 compatible with the hex() and oct() builtins from Python 3.0. They
5552 differ slightly in their output formats from the existing, unchanged
5553 Python 2.6 builtins. The expected usage of the future_builtins
5554 module is:
5555 from future_builtins import hex, oct
5556
Eric Smith7ef40bf2008-02-20 23:34:22 +00005557- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5558 exponents for exponents with absolute value < 100. Follows C99
5559 standard. This is a change on Windows, which would use 3 digits.
5560 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5561 so that any alterations it does to the resulting string will be
5562 available in stringlib/formatter.h (for float.__format__).
5563
Eric Smith5a3c1352008-02-19 13:21:56 +00005564- Implemented PEP 3101, Advanced String Formatting. This adds a new
5565 builtin format(); a format() method for str and unicode; a
5566 __format__() method to object, str, unicode, int, long, float, and
5567 datetime; the class string.Formatter; and the C API
5568 PyObject_Format().
5569
Georg Brandl3ee81df2008-05-17 18:14:43 +00005570- Fixed several potential crashes, all caused by specially crafted
5571 __del__ methods exploiting objects in temporarily inconsistent
5572 state.

5583 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005584
Georg Brandl3ee81df2008-05-17 18:14:43 +00005585- Issue #2045: Fix an infinite recursion triggered when printing a
5586 subclass of collections.defaultdict, if its default_factory is set
5587 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005588
Christian Heimesf75dbef2008-02-08 00:11:31 +00005589- Fixed a minor memory leak in dictobject.c. The content of the free
5590 list was not freed on interpreter shutdown.
5591

5598
Georg Brandl3ee81df2008-05-17 18:14:43 +00005599- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5600 calls. Python expected the return type int but the fork familie
5601 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005612- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5613 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005614
Georg Brandl3ee81df2008-05-17 18:14:43 +00005615- Patch #1473257: generator objects gain a gi_code attribute. This is
5616 the same object as the func_code attribute of the function that
5617 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005618
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619- Issue #1920: "while 0" statements were completely removed by the
5620 compiler, even in the presence of an "else" clause, which is
5621 supposed to be run when the condition is false. Now the compiler
5622 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005623
Guido van Rossumeead05f2008-01-24 18:21:02 +00005624- A few crashers fixed: weakref_in_del.py (issue #1377858);
5625 loosing_dict_ref.py (issue #1303614, test67.py);
5626 borrowed_ref_[34].py (not in tracker).
5627
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005628- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005629 suppressed while an extension is loaded by calling SetErrorMode in
5630 dynload_win.c. The error is still reported properly.
5631
Georg Brandl3ee81df2008-05-17 18:14:43 +00005632- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005633 several extension methods and modules do not work without unicode
5634 support.
5635
Georg Brandl26543b12008-01-21 18:36:51 +00005636- Issue #1882: when compiling code from a string, encoding cookies in the
5637 second line of code were not always recognized correctly.
5638
Georg Brandl14404b62008-01-19 19:27:05 +00005639- Issue #1679: "0x" was taken as a valid integer literal.
5640
Georg Brandl6caad7d2008-01-26 14:19:22 +00005641- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005642 added.
5643
Christian Heimesc94e2b52008-01-14 04:13:37 +00005644- sys.float_info / PyFloat_GetInfo: The floating point information
5645 object was converted from a dict to a specialized structseq object.
5646
Georg Brandl3ee81df2008-05-17 18:14:43 +00005647- Patch #1816: Added sys.flags structseq. It exposes the status of
5648 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005649
Georg Brandl3ee81df2008-05-17 18:14:43 +00005650- Objects/structseq.c: Implemented new structseq representation. The
5651 patch makes structseqs (e.g. the return value of os.stat) more
5652 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005653
Georg Brandl3ee81df2008-05-17 18:14:43 +00005654- Patch #1700288: added a type attribute cache that caches method
5655 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005656
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005657- Bug #1776: __import__() no longer accepts filenames on any platform.
5658 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005659
Georg Brandlaed6c662008-01-07 17:25:53 +00005660- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5661
Georg Brandl3ee81df2008-05-17 18:14:43 +00005662- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5663 envvar and sys.dont_write_bytecode attribute. All these can be set
5664 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005665
Georg Brandl3ee81df2008-05-17 18:14:43 +00005666- Improve some exception messages when Windows fails to load an
5667 extension module. Now we get for example '%1 is not a valid Win32
5668 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005669
Georg Brandl3ee81df2008-05-17 18:14:43 +00005670- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005672- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5673 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005674
Christian Heimes0a8143f2007-12-18 23:22:54 +00005675- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005676 and INF. float("nan"), float("inf") and float("-inf") now work on
5677 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005678
Georg Brandl3ee81df2008-05-17 18:14:43 +00005679- Compiler now generates simpler and faster code for dictionary
5680 literals. The oparg for BUILD_MAP now indicates an estimated
5681 dictionary size. There is a new opcode, STORE_MAP, for adding
5682 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005683
Georg Brandl3ee81df2008-05-17 18:14:43 +00005684- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005685
Georg Brandl3ee81df2008-05-17 18:14:43 +00005686- Issue #1620: New property decorator syntax was modifying the
5687 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005688
Georg Brandl3ee81df2008-05-17 18:14:43 +00005689- Issue #1538: Avoid copying string in split/rsplit if the split char
5690 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005691
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005692- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005693 SystemError.
5694
Nick Coghlanef01d822007-12-03 12:55:17 +00005695- PEP 366: Allow explicit relative imports when executing modules
5696 inside packages with the -m switch via a new module level
5697 __package__ attribute.
5698
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699- Issue #1402: Fix a crash on exit, when another thread is still
5700 running, and if the deallocation of its frames somehow calls the
5701 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005702

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005706 attribute of an empty cell object.
5707
Georg Brandl3ee81df2008-05-17 18:14:43 +00005708- Issue #1460: The utf-7 incremental decoder did not accept truncated
5709 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005710
Georg Brandl3ee81df2008-05-17 18:14:43 +00005711- Patch #1739468: Directories and zipfiles containing a __main__.py
5712 file can now be directly executed by passing their name to the
5713 interpreter. The directory/zipfile is automatically inserted as the
5714 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005715
Georg Brandl3ee81df2008-05-17 18:14:43 +00005716- Issue #1265: Fix a problem with sys.settrace, if the tracing
5717 function uses a generator expression when at the same time the
5718 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005719
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005720- sets and frozensets now have an isdisjoint() method.
5721
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005722- optimize the performance of builtin.sum().
5723
Neal Norwitz44f326e2007-10-05 05:29:17 +00005724- Fix warnings found by the new version of the Coverity checker.
5725
Georg Brandl21e99f42010-03-07 15:23:59 +00005726- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005727 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5728 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005729
Georg Brandl3ee81df2008-05-17 18:14:43 +00005730- Issue #1686386: Tuple's tp_repr did not take into account the
5731 possibility of having a self-referential tuple, which is possible
5732 from C code. Nor did object's tp_str consider that a type's tp_str
5733 could do something that could lead to an inifinite recursion.
5734 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5735 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005736
Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Issue #1164: It was possible to trigger deadlock when using the
5738 'print' statement to write to a file since the GIL was not released
5739 as needed. Now PyObject_Print() does the right thing along with
5740 various tp_print implementations of the built-in types and those in
5741 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005742
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Issue #1147: Exceptions were directly allowing string exceptions in
5744 their throw() method even though string exceptions no longer
5745 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005746
Georg Brandl3ee81df2008-05-17 18:14:43 +00005747- Issue #1096: Prevent a segfault from getting the repr of a very
5748 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005749
Brett Cannon1e534b52007-09-07 04:18:30 +00005750- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751 PyObject_Call() never calling back out to Python code to trigger
5752 recursion depth updates/checks. Required the creation of a static
5753 RuntimeError instance in case normalizing an exception put the
5754 recursion check value past its limit. Fixes crashers
5755 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005756
Georg Brandl3ee81df2008-05-17 18:14:43 +00005757- Patch #1031213: Decode source line in SyntaxErrors back to its
5758 original source encoding.

5761 with %G.
5762
Georg Brandl3ee81df2008-05-17 18:14:43 +00005763- Prevent expandtabs() on string and unicode objects from causing a
5764 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005765

Georg Brandla5ea6892007-06-01 11:33:33 +00005769
Neal Norwitz0ac60192007-05-27 04:08:54 +00005770- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771 __*__ attributes. (Some already existed, e.g., __doc__ and
5772 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005773
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005774- Add -3 option to the interpreter to warn about features that are
5775 deprecated and will be changed/removed in Python 3.0.
5776
Georg Brandl2134e752007-05-21 20:34:16 +00005777- Patch #1686487: you can now pass any mapping after '**' in function
5778 calls.
5779
Collin Winter62903052007-05-18 23:11:24 +00005780- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781 "except E as target:". This is to provide forwards compatibility
5782 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005783
Brett Cannon229cee22007-05-05 01:34:02 +00005784- Deprecate BaseException.message as per PEP 352.
5785
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005787 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005788
Vinay Sajip8549ce32007-05-06 17:53:37 +00005789- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005790 setting a plain string, ie don't expand to single letter identifiers.
5791
Raymond Hettinger13936692007-04-11 18:40:58 +00005792- Request #1191699: Slices can now be pickled.
5793
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005794- Request #1193128: str.translate() now allows a None argument for
5795 translations that only remove characters without re-mapping the
5796 remaining characters.
5797
Georg Brandl5cb76c12007-03-21 09:00:39 +00005798- Patch #1682205: a TypeError while unpacking an iterable is no longer
5799 masked by a generic one with the message "unpack non-sequence".
5800
Neal Norwitzaa754b72007-03-21 06:39:48 +00005801- Remove unused file Python/fmod.c.
5802
Guido van Rossum143b5642007-03-23 04:58:42 +00005803- Bug #1683368: The object.__init__() and object.__new__() methods are
5804 now stricter in rejecting excess arguments. The only time when
5805 either allows excess arguments is when it is not overridden and the
5806 other one is. For backwards compatibility, when both are
5807 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005808 warning later). Also, type.__init__() insists on the same signature
5809 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005810
Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5812 object to complex using its __complex__() method before falling back
5813 to the __float__() method. Therefore, the functions in the cmath
5814 module now can operate on objects that define a __complex__()
5815 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Patch #1623563: allow __class__ assignment for classes with
5818 __slots__. The old and the new class are still required to have the
5819 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005820
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- Patch #1642547: Fix an error/crash when encountering syntax errors
5822 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005824- Patch #1462488: Python no longer segfaults when
5825 ``object.__reduce_ex__()`` is called with an object that is faking
5826 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005827
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Patch #1680015: Don't modify __slots__ tuple if it contains an
5829 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00005831- Patch #1444529: the builtin compile() now accepts keyword arguments.
5832
Georg Brandl7b9c5552007-03-12 14:30:05 +00005833- Bug #1678647: write a newline after printing an exception in any
5834 case, even when converting the value to a string failed.
5835
Georg Brandl871f1bc2007-03-12 13:17:36 +00005836- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005837 its argument, if it exists. If not, it will work like before. This
5838 allows customizing the output of dir() in the presence of a
5839 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005840
Collin Winter276887b2007-03-12 16:11:39 +00005841- Patch #922167: Python no longer segfaults when faced with infinitely
5842 self-recursive reload() calls (as reported by bug #742342).
5843
Georg Brandl3ee81df2008-05-17 18:14:43 +00005844- Patch #1675981: remove unreachable code from ``type.__new__()``
5845 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005846
Georg Brandl3ee81df2008-05-17 18:14:43 +00005847- Patch #1491866: change the complex() constructor to allow
5848 parthensized forms. This means complex(repr(x)) now works instead of
5849 raising a ValueError.

6360 ".cpp" too.
6361
Facundo Batistad918a652007-04-24 13:54:38 +00006362- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006363 the client's request was successfully received, understood, and
6364 accepted. Now in these cases no error is raised in urllib (issue
6365 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006366

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006373- Added a timeout parameter to the constructor of other protocols
6374 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6375 work started with create_connection() and timeout in httplib, and
6376 closes patch #723312.
6377
Vinay Sajip8549ce32007-05-06 17:53:37 +00006378- Patch #1676823: Added create_connection() to socket.py, which may be
6379 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006380 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006381
Martin v. Löwis0af33882007-03-23 13:27:15 +00006382- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006389- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
6390 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00006391 directories.
6392

6394 GNOME or KDE browser, depending on whether there is a session of one
6395 of those present. Also, it tries the Windows default browser before
6396 trying Mozilla variants.

6402
Georg Brandlf66b6032007-03-14 08:27:52 +00006403- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006404 AttributeError instead of an IOError when the server's response
6405 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006406
Georg Brandl3ee81df2008-05-17 18:14:43 +00006407- Patch #957650: "%var%" environment variable references are now
6408 properly expanded in ntpath.expandvars(), also "~user" home
6409 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00006410
Georg Brandl3ee81df2008-05-17 18:14:43 +00006411- Patch #1429539: pdb now correctly initializes the __main__ module
6412 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006413 correctly now.
6414
Georg Brandlbad6f192007-03-13 21:32:56 +00006415- The nonobvious commands.getstatus() function is now deprecated.

6421
Georg Brandl3ee81df2008-05-17 18:14:43 +00006422- Patch #1530482: add pydoc.render_doc() which returns the
6423 documentation for a thing instead of paging it to stdout, which
6424 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006425
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426- Patch #1533909: the timeit module now accepts callables in addition

6432 parameter which can be set to False to prevent the default
6433 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006434
Georg Brandl9e6b4702007-03-13 18:15:41 +00006435- Patch #1581073: add a flag to textwrap that prevents the dropping of
6436 whitespace while wrapping.
6437
Georg Brandl92a6bae2007-03-13 17:43:32 +00006438- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006439 are set for invalid interpolation sequences that would lead to
6440 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006441

6454
Georg Brandl94fe3f52007-03-13 09:32:11 +00006455- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00006456 field names in its exception message if you try to write a record
6457 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00006475

6483 returned string up to the first NUL character.
6484

6494
Georg Brandl3ee81df2008-05-17 18:14:43 +00006495- unittest now verifies more of its assumptions. In particular,
6496 TestCase and TestSuite subclasses (not instances) are no longer
6497 accepted in TestSuite.addTest(). This should cause no
6498 incompatibility since it never made sense with ordinary subclasses
6499 -- the failure just occurred later, with a more cumbersome
6500 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006501

6509 given a unicode argument and os.listdir() returns unicode filenames.
6510
Georg Brandl3ee81df2008-05-17 18:14:43 +00006511- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006889 time so that opening a database previously created with the DB_DUP
6890 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6891 opens. Specifically: dictionary assignment to a DB object will
6892 replace all values for a given key when the database allows
6893 duplicate values. DB users should use DB.put(k, v) when they want
6894 to store duplicates; not DB[k] = v.

6901 characters with ASCII value less than 32. Also, it correctly quotes
6902 dots only if they occur on a single line, as opposed to the previous
6903 behavior of quoting dots if they are the second character of any
6904 line.
