145
Ned Deily87e82bb2011-06-28 19:52:59 -0700146- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
147 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
148 interpreter process. This could cause failures in non-Distutils subprocesses
149 and was unreliable since tests or user programs could modify the interpreter
150 environment after Distutils set it. Instead, have Distutils set the the
151 deployment target only in the environment of each build subprocess. It is
152 still possible to globally override the default by setting
153 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
154 greater or equal to the default value, the value with which the interpreter
155 was built.

161 Kitada.
162
R David Murrayf1138bb2011-06-17 22:23:04 -0400163- Issue #11700: mailbox proxy object close methods can now be called multiple
164 times without error, and _ProxyFile now closes the wrapped file.
165
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200166- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
167 connection if its getresponse() method fails with a socket error. Patch
168 written by Ezio Melotti.
169
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500170- Issue #9284: Allow inspect.findsource() to find the source of doctest
171 functions.
172

174
Brian Curtincaea7e82011-06-08 19:29:53 -0500175- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes

177

179 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
180

182
Barry Warsawc5643282011-07-19 17:06:30 -0400183- sys.setcheckinterval() now updates the current ticker count as well as
184 updating the check interval, so if the user decreases the check interval,
185 the ticker doesn't have to wind down to zero from the old starting point
186 before the new interval takes effect. And if the user increases the
187 interval, it makes sure the new limit takes effect right away rather have an
188 early task switch before recognizing the new interval.

1058 This prevents user-created self-referencing ordered dictionaries from
1059 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001521- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1522 start byte and the continuation byte(s) are now considered invalid, instead
1523 of the number of bytes specified by the start byte.
1524 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1525 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1526 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1527 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001529- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001530 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1531 arises from the "Overriding __eq__ blocks inheritance ..." warning
1532 when turned into an exception: in this case the exception simply
1533 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001534
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001535- Issue #8748: Fix two issues with comparisons between complex and integer
1536 objects. (1) The comparison could incorrectly return True in some cases
1537 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1538 (2) The comparison raised an OverflowError for large integers, leading
1539 to unpredictable exceptions when combining integers and complex objects
1540 in sets or dicts.
1541
Mark Dickinson81336372010-05-30 12:12:25 +00001542- Issue #5211: Implicit coercion for the complex type is now completely
1543 removed. (Coercion for arithmetic operations was already removed in 2.7
1544 alpha 4, but coercion for rich comparisons was accidentally left in.)
1545
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001546- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1547 and error handler, instead of writing to the C stderr file in utf-8
1548
Georg Brandlfee0f442010-05-22 21:26:21 +00001549- Issue #7902: When using explicit relative import syntax, don't try implicit

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001907- Issue #7301: Add environment variable $PYTHONWARNINGS.
1908
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001909- Issue #8329: Don't return the same lists from select.select when no fds are
1910 changed.
1911
Georg Brandlfee0f442010-05-22 21:26:21 +00001912- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001913 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00001922- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1923 with a non-empty format string. This is an effort to future-proof user
1924 code. If a derived class does not currently implement __format__ but later
1925 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001926 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001927 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001987- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001988 argument `-` which tells it to read files to compile from stdin. Each line is
1989 read on demand and the named file is compiled immediately. (Original patch by

Antoine Pitroud840e512010-02-04 20:20:18 +00002412- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002413 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002414 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00002420 file position when calling `truncate()`. It would previously change the file
2421 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002422 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2425 class used to represent files stored inside an archive. The new
2426 implementation is significantly faster and can be wrapped in a
2427 ``io.BufferedReader`` object for more speedups. It also solves an issue
2428 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2441 encoded string for them. This ensures that the upload and register commands
2442 send the correct values to PyPI without any error.

2518
Georg Brandlba83f822010-03-14 09:50:54 +00002519- The ``__complex__()`` method is now looked up on the class of instances to
2520 make it consistent with other special methods.

2524
Mark Dickinson1b34d252010-01-01 17:27:30 +00002525- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002526 DeprecationWarning when passed a float argument where an integer was expected.
2527 These functions and methods now raise TypeError instead. The majority of the
2528 effects of this change are in the extension modules, but some core functions
2529 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2530 and many unicode/str methods.

2544 of integers: the result of a/b is now correctly rounded for ints a and b (at
2545 least on IEEE 754 platforms), and in particular does not depend on the
2546 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00002555 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002713- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2714 decimal string that's guaranteed to round back to x under correct rounding
2715 (with round-half-to-even rounding mode). Previously it gave a string based on
2716 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2717 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2718 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002720- Issue #7117: On almost all platforms: float-to-string and string-to-float
2721 conversions within Python are now correctly rounded. Places these conversions
2722 occur include: str for floats and complex numbers; the float and complex
2723 constructors; old-style and new-style numeric formatting; serialization and
2724 deserialization of floats and complex numbers using marshal, pickle and json;
2725 parsing of float and imaginary literals in Python code; Decimal-to-float
2726 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002727
Georg Brandlba83f822010-03-14 09:50:54 +00002728 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2729 providing correctly-rounded strtod and dtoa C functions. This code is
2730 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2731 the C compiler. There may be a small number of platforms on which correct
2732 operation of this code cannot be guaranteed, so the code is not used: notably,
2733 this applies to platforms where the C double format is not IEEE 754 binary64,
2734 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2735 and Python's configure script is unable to determine how to change the FPU
2736 precision. On these platforms conversions use the platform strtod and dtoa,
2737 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002739- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2740 uses the correctly-rounded string <-> float conversions described above (when
2741 available), and so produces correctly rounded results that will display nicely
2742 under the float repr. There are two related small changes: (1) round now
2743 accepts any class with an ``__index__()`` method for its second argument (but
2744 no longer accepts floats for the second argument), and (2) an excessively
2745 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2746 raises an exception.

3125 this code path is really executed because I cannot move to such directory on

Brett Cannon764465f2009-08-13 19:27:12 +00004310
Georg Brandlba83f822010-03-14 09:50:54 +00004311- Issue #6561: '\d' in a regex now matches only characters with Unicode category
4312 'Nd' (Number, Decimal Digit). Previously it also matched characters with
4313 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00004314
Georg Brandlba83f822010-03-14 09:50:54 +00004315- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
4316 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4317 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00004318
Georg Brandlba83f822010-03-14 09:50:54 +00004319- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the
4320 integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=',
4321 '<', '>'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004322
Georg Brandlba83f822010-03-14 09:50:54 +00004323 - Packing a float now always gives a Deprecation Warning. Previously it
4324 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004325
Georg Brandlba83f822010-03-14 09:50:54 +00004326 - If x is not an int, long or float, then packing x will always result in
4327 struct.error. Previously an x with an __int__ method could be packed by
4328 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4329 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4330 neither __int__ nor __long__, TypeError used to be raised (with a
4331 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4332 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004333
Georg Brandlba83f822010-03-14 09:50:54 +00004334 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4335 argument with an __int__ method can be packed, but use of this feature
4336 triggers a DeprecationWarning.
Mark Dickinson154b7ad2010-03-07 16:24:45 +00004337
Martin v. Löwis4f16d3b2009-05-29 15:58:08 +00004338- Issue #4873: Fix resource leaks in error cases of pwd and grp.

4344 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00004345 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00004369- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4370 in the Lib/test directory, which might be read-only for the user running the
4371 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00004372
Georg Brandlba83f822010-03-14 09:50:54 +00004373- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
4374 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00004375
Georg Brandlba83f822010-03-14 09:50:54 +00004376- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
4377 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00004378
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00004379- Issue #7295: Do not use a hardcoded file name in test_tarfile.
4380
Antoine Pitrouc98efe02009-11-06 22:34:35 +00004381- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
4382 primitives such as Lock, RLock, Condition, Event and Semaphore.
4383
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004384- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00004385 leak-chasing test runs give sensible results. The previous method of reaping
4386 threads could return successfully while some Thread objects were still
4387 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004388
Georg Brandlba83f822010-03-14 09:50:54 +00004389- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
4390 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00004391
Antoine Pitrou58d2f262009-10-10 20:52:11 +00004392- Issue #7055: test___all__ now greedily detects all modules which have an
4393 __all__ attribute, rather than using a hardcoded and incomplete list.
4394
R. David Murray14dcd432009-10-14 13:58:07 +00004395- Issue #7058: Added save/restore for things like sys.argv and cwd to
4396 runtest_inner in regrtest, with warnings if the called test modifies them,
4397 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00004398
Mark Dickinson245d9152009-10-04 18:38:39 +00004399- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

Brett Cannone7e941e2009-09-03 21:25:21 +00004401- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
4402 off the trailing 0 in the version number.
4403
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004404- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4405 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004406 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4407 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004408
Antoine Pitrou4698d992009-05-31 14:20:14 +00004409- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4410 regression tests in parallel, shortening the total runtime.
4411
Georg Brandlba83f822010-03-14 09:50:54 +00004412- Issue #5354: New test support function import_fresh_module() makes it easy to
4413 import both normal and optimised versions of modules. test_heapq and
4414 test_warnings have been adjusted to use it, tests for other modules with both
4415 C and Python implementations in the stdlib can be adjusted to use it over
4416 time.

4423
Georg Brandlba83f822010-03-14 09:50:54 +00004424- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4425 should cause a test to be skipped are now done using import_module from test
4426 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00004427
Guilherme Polob1a98de2009-01-28 20:03:26 +00004428- Issue #5083: New 'gui' resource for regrtest.

4528
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004529- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4530 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4531 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4532 ``printf`` function, whereas PyString_FromFormat has an independent
4533 implementation and uses "%zd" on all platforms for size_t values.
4534 This makes a difference on win64, where ``printf`` needs "%Id" to display
4535 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004537- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004550- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004551 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004552 was correctly parsed but parsing of subsequent arguments failed.
4553
Vinay Sajip35e3b032008-09-01 14:33:59 +00004554- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004555 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4556 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4557 when given a tuple of classes as second argument, were looking up
4558 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4559 type object.
4560

Brett Cannon1eaf0742008-09-02 01:25:16 +00004630 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4631 for catch_warnings() also led to an improvement in the raising of a
4632 DeprecationWarning related to warnings.warn_explicit().
4633
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004634- The deprecation warnings for the old camelCase threading API were removed.

4656
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004657- Issue #2975: When compiling several extension modules with Visual Studio 2008
4658 from the same python interpreter, some environment variables would grow
4659 without limit.
4660
Benjamin Peterson37346b22008-08-23 20:27:43 +00004661- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004698What's New in Python 2.6 beta 3?
4699================================
4700
Barry Warsaw07a4a382008-08-21 01:15:08 +00004701*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004702
4703Core and Builtins
4704-----------------
4705
Guido van Rossumf8402962008-08-20 15:01:50 +00004706- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4707 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4708 extensions do not automatically benefit from the class attribute
4709 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4710 to their tp_flags field if they care. This is a backwards
4711 compatibility feature; in 3.0, all types will use the cache by
4712 default.
4713
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004714- Keyword arguments can now follow starred arguments. (``f(a, *args,
4715 keyword=23)`` is now valid syntax.)
4716
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004717- ctypes function pointers that are COM methods have a boolean True
4718 value again.
4719
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004720- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4721 by denying s# to parse objects that have a releasebuffer procedure,
4722 and introducing s*.
4723
Georg Brandl1e13ea92008-08-11 09:07:59 +00004724- Issue #3537: Fix an assertion failure when an empty but presized dict
4725 object was stored in the freelist.
4726
Mark Dickinsonb6467572008-08-04 21:30:09 +00004727- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4728 ValueError consistently across platforms.
4729
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004730- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4731 (64bit Unix, for example), unichr() would truncate its argument and return
4732 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4733
Neal Norwitze7d8be82008-07-31 17:17:14 +00004734- Apply security patches from Apple.
4735
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004736- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4737 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4738
Antoine Pitrou92f82162008-07-25 22:22:08 +00004739- Issue #1819: function calls with several named parameters are now on
4740 average 35% faster (as measured by pybench).
4741
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004742- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4743 the python debugger steps into a class statement: the free variables (local
4744 variables defined in an outer scope) would be deleted from the outer scope.
4745
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004746- Issue #2620: Overflow checking when allocating or reallocating memory
4747 was not always being done properly in some python types and extension
4748 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4749 all been updated to perform better checks and places in the code that
4750 would previously leak memory on the error path when such an allocation
4751 failed have been fixed.

4754-------
4755
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004756- Issue #3612: Added some missing basic types in ctypes.wintypes.
4757
Benjamin Petersone977ad42008-08-20 01:42:01 +00004758- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4759 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4760
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004761- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4762 version reported by these tools does not necessarily follow the python
4763 version numbering scheme, so the module is less strict when parsing it.
4764
Nick Coghlanf70385a2008-08-18 12:42:46 +00004765- Issue #2235: Added Py3k warnings for types which will become unhashable
4766 under the stricter __hash__ inheritance rules in 3.0. Several types
4767 which did not meet the rules for hash invariants and were already
4768 unhashable in 3.0 have now been explicitly flagged as unhashable in
4769 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4770 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4771
Brett Cannon88f801d2008-08-18 00:46:22 +00004772- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4773 imported into the module but exposed as part of the module's API.
4774
Brett Cannon7b96f072008-08-18 00:41:11 +00004775- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4776
Brett Cannon46225e72008-08-18 00:36:52 +00004777- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004779- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4780
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004781- Issue #3575: Incremental decoder's decode function now takes bytearray
4782 by using 's*' instead of 't#'.
4783
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004784- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004785 fails unicode conversion on 2nd parameter. (windows only)
4786
Georg Brandl222e2082010-08-01 22:27:39 +00004787- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004788 in a redirect.
4789
Brett Cannonabe423e2008-08-16 21:47:07 +00004790- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004791 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004792
Facundo Batistaeb90b782008-08-16 14:44:07 +00004793- Issue #2776: fixed small issue when handling an URL with double slash
4794 after a 302 response in the case of not going through a proxy.
4795
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004796- Issue #2676: in the email package, content-type parsing was hanging on
4797 pathological input because of quadratic or exponential behaviour of a
4798 regular expression.
4799
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004800- Issue #3476: binary buffered reading through the new "io" library is now
4801 thread-safe.
4802
Brett Cannonbf3157b2008-08-14 05:00:03 +00004803- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4804 since mimetools itself is deprecated. Because modules are cached, all
4805 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4806
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004807- Issue #3134: shutil referenced undefined WindowsError symbol.
4808
Robert Schuppenies14646332008-08-10 11:01:53 +00004809- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4810 menu entries were not deleted.
4811
Brett Cannon83e81842008-08-09 23:30:55 +00004812- Copied the implementation of reduce() to _functools.reduce() to have a
4813 version that did not raise a DeprecationWarning under -3.
4814
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004815- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4816 a MemoryError rather than silently stop the iteration.
4817
Guido van Rossum59ce9012008-08-09 14:55:34 +00004818- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4819 to _sre.compile() will now be rejected. This should not affect anybody
4820 since the re.compile() function never generates invalid re-bytecode.
4821
Skip Montanaroa032bf42008-08-08 22:52:51 +00004822- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4823 upon first access it can be automatically initialized from the csv file if
4824 it wasn't initialized during instantiation.
4825
Brett Cannon3aa2a492008-08-06 22:28:09 +00004826- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4827 the reload() built-in has been removed.
4828
Brett Cannon7e30b672008-08-04 21:52:25 +00004829- Changed code in the following modules/packages to remove warnings raised

4898-----------------
4899
Georg Brandl3e483f62008-07-16 22:57:41 +00004900- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4901 its methods now allow for items objects that can be converted to
4902 an integer using operator.index().
4903
Mark Dickinson64b7e502008-07-16 09:40:03 +00004904- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4905 produced a ValueError instead of giving the correct float.
4906
Eric Smitha5fa5a22008-07-16 00:11:49 +00004907- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4908 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4909
Mark Dickinson7103aa42008-07-15 19:08:33 +00004910- Issue #3008: the float type has a new instance method 'float.hex'
4911 and a new class method 'float.fromhex' to convert floating-point
4912 numbers to and from hexadecimal strings, respectively.
4913
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004914- Issue #2235: __hash__ is once again inherited by default. To allow
4915 collections.Hashable to remain meaningful in the presence of the
4916 default hash implementation (object.__hash__), it is now possible
4917 to explicit block inheritance of hash by setting __hash__=None at
4918 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4919 level.
4920
Nick Coghlanb028f502008-07-13 14:52:36 +00004921- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4922 the parent module cannot be found while performing an absolute import.
4923 This means that an incorrectly defined __package__ attribute will
4924 now only prevent relative imports in that module rather than causing
4925 all imports from that module to fail.
4926
Nick Coghlan14ff9942008-07-08 14:21:42 +00004927- Issue #2517: Allow unicode messages in Exceptions again by correctly

4937 another thread's dictionary.
4938
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004939- Issue #3004: Minor change to slice.indices(): the start and stop
4940 arguments are now treated identically, making the behaviour easier
4941 to describe and understand. For example, slice(None, -10,
4942 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4943 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4944 10, -1).
4945
Georg Brandl278fc502008-07-19 12:46:12 +00004946- Issue #3219: Calling a function with repeated keyword arguments,
4947 f(a=2, a=23), would not cause a syntax error. This was a regression
4948 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004986- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4987 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004988 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004989 content-length. The problem had been corrected in the 2.4 branch, but never
4990 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005005- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5006 handling is now the same as that of other special attributes like __name__).
5007
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005008- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005396- On MacOS X it is now possible to install the framework in 64-bit
5397 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005398 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005399
5400 This is controlled by the configure argument ``--with-universal-archs``:
5401
5402 - ``--with-universal-archs=all``: install 4-way universal
5403
5404 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5405
5406 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5407
5408 This option should be used in combination with ``--enable-universalsdk=``.
5409
5410 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5415
Georg Brandl74a1dea2008-05-28 11:21:39 +00005416- Add ``PyType_Modified()`` as a public API to clear the type cache.
5417
5418- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005419
5420- The PyString functions have been renamed to PyBytes. A batch of
5421 defines were added so that the linker still sees the original
5422 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005460- Issue #1631171: Re-implement the 'warnings' module in C (the
5461 original Python code has been kept as backup). This will allow for
5462 using the 'warning's machinery in such places as the parser where
5463 use of pure Python code is not possible. Both the ``showarning()``
5464 and ``formatwarning()`` gain an optional 'line' argument which is
5465 not called by default for backwards-compatibility reasons. Setting
5466 ``warnings.showwarning()`` to an implementation that lacks support
5467 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005492- The getpass module has been improved on Unix. It now uses /dev/tty
5493 by default and uses stderr instead of stdout. A GetPassWarning is
5494 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005510 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005530- Issue #2550: The approach used by client/server code for obtaining
5531 ports to listen on in network-oriented tests has been refined in an
5532 effort to facilitate running multiple instances of the entire
5533 regression test suite in parallel without issue.
5534 test_support.bind_port() has been fixed such that it will always
5535 return a unique port -- which wasn't always the case with the
5536 previous implementation, especially if socket options had been set
5537 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5538 new implementation of bind_port() will actually raise an exception
5539 if it is passed an AF_INET/SOCK_STREAM socket with either the
5540 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5541 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5542 the socket it's been passed. This currently only applies to
5543 Windows. This option prevents any other sockets from binding to the
5544 host/port we've bound to, thus removing the possibility of the
5545 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5546 when a second SOCK_STREAM socket binds and accepts to a host/port
5547 that's already been bound by another socket. The optional preferred
5548 port parameter to bind_port() has been removed. Under no
5549 circumstances should tests be hard coding ports!
5550
5551 test_support.find_unused_port() has also been introduced, which will
5552 pass a temporary socket object to bind_port() in order to obtain an
5553 unused port. The temporary socket object is then closed and
5554 deleted, and the port is returned. This method should only be used
5555 for obtaining an unused port in order to pass to an external program
5556 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5557 a parameter to a server-oriented class that doesn't give you direct
5558 access to the underlying socket used.
5559
5560 Finally, test_support.HOST has been introduced, which should be used
5561 for the host argument of any relevant socket calls (i.e. bind and
5562 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005563
5564 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005565 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005566 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5567 test_asynchat and test_socket_ssl.
5568
Georg Brandl3ee81df2008-05-17 18:14:43 +00005569 It is now possible for multiple instances of the regression test
5570 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005849- Added the future_builtins module, which contains hex() and oct().
5850 These are the PEP 3127 version of these functions, designed to be
5851 compatible with the hex() and oct() builtins from Python 3.0. They
5852 differ slightly in their output formats from the existing, unchanged
5853 Python 2.6 builtins. The expected usage of the future_builtins
5854 module is:
5855 from future_builtins import hex, oct
5856
Eric Smith7ef40bf2008-02-20 23:34:22 +00005857- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5858 exponents for exponents with absolute value < 100. Follows C99
5859 standard. This is a change on Windows, which would use 3 digits.
5860 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5861 so that any alterations it does to the resulting string will be
5862 available in stringlib/formatter.h (for float.__format__).
5863
Eric Smith5a3c1352008-02-19 13:21:56 +00005864- Implemented PEP 3101, Advanced String Formatting. This adds a new
5865 builtin format(); a format() method for str and unicode; a
5866 __format__() method to object, str, unicode, int, long, float, and
5867 datetime; the class string.Formatter; and the C API
5868 PyObject_Format().
5869
Georg Brandl3ee81df2008-05-17 18:14:43 +00005870- Fixed several potential crashes, all caused by specially crafted
5871 __del__ methods exploiting objects in temporarily inconsistent
5872 state.

5883 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005884
Georg Brandl3ee81df2008-05-17 18:14:43 +00005885- Issue #2045: Fix an infinite recursion triggered when printing a
5886 subclass of collections.defaultdict, if its default_factory is set
5887 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005888
Christian Heimesf75dbef2008-02-08 00:11:31 +00005889- Fixed a minor memory leak in dictobject.c. The content of the free
5890 list was not freed on interpreter shutdown.
5891

5898
Georg Brandl3ee81df2008-05-17 18:14:43 +00005899- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005912- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5913 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005914
Georg Brandl3ee81df2008-05-17 18:14:43 +00005915- Patch #1473257: generator objects gain a gi_code attribute. This is
5916 the same object as the func_code attribute of the function that
5917 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005918
Georg Brandl3ee81df2008-05-17 18:14:43 +00005919- Issue #1920: "while 0" statements were completely removed by the
5920 compiler, even in the presence of an "else" clause, which is
5921 supposed to be run when the condition is false. Now the compiler
5922 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005923
Guido van Rossumeead05f2008-01-24 18:21:02 +00005924- A few crashers fixed: weakref_in_del.py (issue #1377858);
5925 loosing_dict_ref.py (issue #1303614, test67.py);
5926 borrowed_ref_[34].py (not in tracker).
5927
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005928- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005929 suppressed while an extension is loaded by calling SetErrorMode in
5930 dynload_win.c. The error is still reported properly.
5931
Georg Brandl3ee81df2008-05-17 18:14:43 +00005932- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005933 several extension methods and modules do not work without unicode
5934 support.
5935
Georg Brandl26543b12008-01-21 18:36:51 +00005936- Issue #1882: when compiling code from a string, encoding cookies in the
5937 second line of code were not always recognized correctly.
5938
Georg Brandl14404b62008-01-19 19:27:05 +00005939- Issue #1679: "0x" was taken as a valid integer literal.
5940
Georg Brandl6caad7d2008-01-26 14:19:22 +00005941- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005942 added.
5943
Christian Heimesc94e2b52008-01-14 04:13:37 +00005944- sys.float_info / PyFloat_GetInfo: The floating point information
5945 object was converted from a dict to a specialized structseq object.
5946
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947- Patch #1816: Added sys.flags structseq. It exposes the status of
5948 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Objects/structseq.c: Implemented new structseq representation. The
5951 patch makes structseqs (e.g. the return value of os.stat) more
5952 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005953
Georg Brandl3ee81df2008-05-17 18:14:43 +00005954- Patch #1700288: added a type attribute cache that caches method
5955 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005956
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005957- Bug #1776: __import__() no longer accepts filenames on any platform.
5958 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005959
Georg Brandlaed6c662008-01-07 17:25:53 +00005960- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5961
Georg Brandl3ee81df2008-05-17 18:14:43 +00005962- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5963 envvar and sys.dont_write_bytecode attribute. All these can be set
5964 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005965
Georg Brandl3ee81df2008-05-17 18:14:43 +00005966- Improve some exception messages when Windows fails to load an
5967 extension module. Now we get for example '%1 is not a valid Win32
5968 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005969
Georg Brandl3ee81df2008-05-17 18:14:43 +00005970- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005972- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5973 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005974
Christian Heimes0a8143f2007-12-18 23:22:54 +00005975- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976 and INF. float("nan"), float("inf") and float("-inf") now work on
5977 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005978
Georg Brandl3ee81df2008-05-17 18:14:43 +00005979- Compiler now generates simpler and faster code for dictionary
5980 literals. The oparg for BUILD_MAP now indicates an estimated
5981 dictionary size. There is a new opcode, STORE_MAP, for adding
5982 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005983
Georg Brandl3ee81df2008-05-17 18:14:43 +00005984- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005985
Georg Brandl3ee81df2008-05-17 18:14:43 +00005986- Issue #1620: New property decorator syntax was modifying the
5987 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Issue #1538: Avoid copying string in split/rsplit if the split char
5990 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005991
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005992- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005993 SystemError.
5994
Nick Coghlanef01d822007-12-03 12:55:17 +00005995- PEP 366: Allow explicit relative imports when executing modules
5996 inside packages with the -m switch via a new module level
5997 __package__ attribute.
5998
Georg Brandl3ee81df2008-05-17 18:14:43 +00005999- Issue #1402: Fix a crash on exit, when another thread is still
6000 running, and if the deallocation of its frames somehow calls the
6001 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006002

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006006 attribute of an empty cell object.
6007
Georg Brandl3ee81df2008-05-17 18:14:43 +00006008- Issue #1460: The utf-7 incremental decoder did not accept truncated
6009 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006010
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011- Patch #1739468: Directories and zipfiles containing a __main__.py
6012 file can now be directly executed by passing their name to the
6013 interpreter. The directory/zipfile is automatically inserted as the
6014 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006015
Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- Issue #1265: Fix a problem with sys.settrace, if the tracing
6017 function uses a generator expression when at the same time the
6018 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006019
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006020- sets and frozensets now have an isdisjoint() method.
6021
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006022- optimize the performance of builtin.sum().
6023
Neal Norwitz44f326e2007-10-05 05:29:17 +00006024- Fix warnings found by the new version of the Coverity checker.
6025
Georg Brandl21e99f42010-03-07 15:23:59 +00006026- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6028 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006029
Georg Brandl3ee81df2008-05-17 18:14:43 +00006030- Issue #1686386: Tuple's tp_repr did not take into account the
6031 possibility of having a self-referential tuple, which is possible
6032 from C code. Nor did object's tp_str consider that a type's tp_str
6033 could do something that could lead to an inifinite recursion.
6034 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6035 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006036
Georg Brandl3ee81df2008-05-17 18:14:43 +00006037- Issue #1164: It was possible to trigger deadlock when using the
6038 'print' statement to write to a file since the GIL was not released
6039 as needed. Now PyObject_Print() does the right thing along with
6040 various tp_print implementations of the built-in types and those in
6041 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006042
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- Issue #1147: Exceptions were directly allowing string exceptions in
6044 their throw() method even though string exceptions no longer
6045 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006046
Georg Brandl3ee81df2008-05-17 18:14:43 +00006047- Issue #1096: Prevent a segfault from getting the repr of a very
6048 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006049
Brett Cannon1e534b52007-09-07 04:18:30 +00006050- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051 PyObject_Call() never calling back out to Python code to trigger
6052 recursion depth updates/checks. Required the creation of a static
6053 RuntimeError instance in case normalizing an exception put the
6054 recursion check value past its limit. Fixes crashers
6055 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006056
Georg Brandl3ee81df2008-05-17 18:14:43 +00006057- Patch #1031213: Decode source line in SyntaxErrors back to its
6058 original source encoding.

6061 with %G.
6062
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Prevent expandtabs() on string and unicode objects from causing a
6064 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006065

Georg Brandla5ea6892007-06-01 11:33:33 +00006069
Neal Norwitz0ac60192007-05-27 04:08:54 +00006070- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071 __*__ attributes. (Some already existed, e.g., __doc__ and
6072 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006073
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006074- Add -3 option to the interpreter to warn about features that are
6075 deprecated and will be changed/removed in Python 3.0.
6076
Georg Brandl2134e752007-05-21 20:34:16 +00006077- Patch #1686487: you can now pass any mapping after '**' in function
6078 calls.
6079
Collin Winter62903052007-05-18 23:11:24 +00006080- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081 "except E as target:". This is to provide forwards compatibility
6082 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006083
Brett Cannon229cee22007-05-05 01:34:02 +00006084- Deprecate BaseException.message as per PEP 352.
6085
Georg Brandl3ee81df2008-05-17 18:14:43 +00006086- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006087 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006088
Vinay Sajip8549ce32007-05-06 17:53:37 +00006089- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006090 setting a plain string, ie don't expand to single letter identifiers.
6091
Raymond Hettinger13936692007-04-11 18:40:58 +00006092- Request #1191699: Slices can now be pickled.
6093
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006094- Request #1193128: str.translate() now allows a None argument for
6095 translations that only remove characters without re-mapping the
6096 remaining characters.
6097
Georg Brandl5cb76c12007-03-21 09:00:39 +00006098- Patch #1682205: a TypeError while unpacking an iterable is no longer
6099 masked by a generic one with the message "unpack non-sequence".
6100
Neal Norwitzaa754b72007-03-21 06:39:48 +00006101- Remove unused file Python/fmod.c.
6102
Guido van Rossum143b5642007-03-23 04:58:42 +00006103- Bug #1683368: The object.__init__() and object.__new__() methods are
6104 now stricter in rejecting excess arguments. The only time when
6105 either allows excess arguments is when it is not overridden and the
6106 other one is. For backwards compatibility, when both are
6107 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006108 warning later). Also, type.__init__() insists on the same signature
6109 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006110
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6112 object to complex using its __complex__() method before falling back
6113 to the __float__() method. Therefore, the functions in the cmath
6114 module now can operate on objects that define a __complex__()
6115 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006116
Georg Brandl3ee81df2008-05-17 18:14:43 +00006117- Patch #1623563: allow __class__ assignment for classes with
6118 __slots__. The old and the new class are still required to have the
6119 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006120
Georg Brandl3ee81df2008-05-17 18:14:43 +00006121- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00006124- Patch #1462488: Python no longer segfaults when
6125 ``object.__reduce_ex__()`` is called with an object that is faking
6126 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006127
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00006131- Patch #1444529: the builtin compile() now accepts keyword arguments.
6132
Georg Brandl7b9c5552007-03-12 14:30:05 +00006133- Bug #1678647: write a newline after printing an exception in any
6134 case, even when converting the value to a string failed.
6135
Georg Brandl871f1bc2007-03-12 13:17:36 +00006136- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006137 its argument, if it exists. If not, it will work like before. This
6138 allows customizing the output of dir() in the presence of a
6139 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006140
Collin Winter276887b2007-03-12 16:11:39 +00006141- Patch #922167: Python no longer segfaults when faced with infinitely
6142 self-recursive reload() calls (as reported by bug #742342).
6143
Georg Brandl3ee81df2008-05-17 18:14:43 +00006144- Patch #1675981: remove unreachable code from ``type.__new__()``
6145 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006146
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147- Patch #1491866: change the complex() constructor to allow
6148 parthensized forms. This means complex(repr(x)) now works instead of
6149 raising a ValueError.

6660 ".cpp" too.
6661
Facundo Batistad918a652007-04-24 13:54:38 +00006662- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006663 the client's request was successfully received, understood, and
6664 accepted. Now in these cases no error is raised in urllib (issue
6665 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006666

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006673- Added a timeout parameter to the constructor of other protocols
6674 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6675 work started with create_connection() and timeout in httplib, and
6676 closes patch #723312.
6677
Vinay Sajip8549ce32007-05-06 17:53:37 +00006678- Patch #1676823: Added create_connection() to socket.py, which may be
6679 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006680 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006681
Martin v. Löwis0af33882007-03-23 13:27:15 +00006682- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006689- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
6690 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00006691 directories.
6692

6694 GNOME or KDE browser, depending on whether there is a session of one
6695 of those present. Also, it tries the Windows default browser before
6696 trying Mozilla variants.

6702
Georg Brandlf66b6032007-03-14 08:27:52 +00006703- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006704 AttributeError instead of an IOError when the server's response
6705 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006706
Georg Brandl3ee81df2008-05-17 18:14:43 +00006707- Patch #957650: "%var%" environment variable references are now
6708 properly expanded in ntpath.expandvars(), also "~user" home
6709 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00006710
Georg Brandl3ee81df2008-05-17 18:14:43 +00006711- Patch #1429539: pdb now correctly initializes the __main__ module
6712 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006713 correctly now.
6714
Georg Brandlbad6f192007-03-13 21:32:56 +00006715- The nonobvious commands.getstatus() function is now deprecated.

6721
Georg Brandl3ee81df2008-05-17 18:14:43 +00006722- Patch #1530482: add pydoc.render_doc() which returns the
6723 documentation for a thing instead of paging it to stdout, which
6724 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006725
Georg Brandl3ee81df2008-05-17 18:14:43 +00006726- Patch #1533909: the timeit module now accepts callables in addition

6732 parameter which can be set to False to prevent the default
6733 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006734
Georg Brandl9e6b4702007-03-13 18:15:41 +00006735- Patch #1581073: add a flag to textwrap that prevents the dropping of
6736 whitespace while wrapping.
6737
Georg Brandl92a6bae2007-03-13 17:43:32 +00006738- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006739 are set for invalid interpolation sequences that would lead to
6740 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006741

6754
Georg Brandl94fe3f52007-03-13 09:32:11 +00006755- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00006756 field names in its exception message if you try to write a record
6757 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00006775

6783 returned string up to the first NUL character.
6784

6794
Georg Brandl3ee81df2008-05-17 18:14:43 +00006795- unittest now verifies more of its assumptions. In particular,
6796 TestCase and TestSuite subclasses (not instances) are no longer
6797 accepted in TestSuite.addTest(). This should cause no
6798 incompatibility since it never made sense with ordinary subclasses
6799 -- the failure just occurred later, with a more cumbersome
6800 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006801

6809 given a unicode argument and os.listdir() returns unicode filenames.
6810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007189 time so that opening a database previously created with the DB_DUP
7190 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7191 opens. Specifically: dictionary assignment to a DB object will
7192 replace all values for a given key when the database allows
7193 duplicate values. DB users should use DB.put(k, v) when they want
7194 to store duplicates; not DB[k] = v.

7201 characters with ASCII value less than 32. Also, it correctly quotes
7202 dots only if they occur on a single line, as opposed to the previous
7203 behavior of quoting dots if they are the second character of any
7204 line.
