Florent Xiclunac2279652012-02-12 14:49:03 +0100614- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100615 has left two versions of customize_compiler, the original in
616 distutils.sysconfig and another copy in distutils.ccompiler, with some
617 parts of distutils calling one and others using the other.
618 Complete the revert back to only having one in distutils.sysconfig as
619 is the case in 3.x.
620
Ned Deily0d0ea482012-02-10 12:59:06 +0100621- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
622 Distutils-based packages with C extension modules may fail because
623 Apple has removed gcc-4.2, the version used to build python.org
624 64-bit/32-bit Pythons. If the user does not explicitly override
625 the default C compiler by setting the CC environment variable,
626 Distutils will now attempt to compile extension modules with clang
627 if gcc-4.2 is required but not found. Also as a convenience, if
628 the user does explicitly set CC, substitute its value as the default
629 compiler in the Distutils LDSHARED configuration variable for OS X.
630 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
631 SDK, neither of which are available in Xcode 4. This change does not
632 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700905- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
906 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
907 interpreter process. This could cause failures in non-Distutils subprocesses
908 and was unreliable since tests or user programs could modify the interpreter
909 environment after Distutils set it. Instead, have Distutils set the the
910 deployment target only in the environment of each build subprocess. It is
911 still possible to globally override the default by setting
912 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
913 greater or equal to the default value, the value with which the interpreter
914 was built.

943 updating the check interval, so if the user decreases the check interval,
944 the ticker doesn't have to wind down to zero from the old starting point
945 before the new interval takes effect. And if the user increases the
946 interval, it makes sure the new limit takes effect right away rather have an
947 early task switch before recognizing the new interval.

1899 This prevents user-created self-referencing ordered dictionaries from
1900 becoming permanently uncollectable GC garbage. The downside is that

2361
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002362- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2363 start byte and the continuation byte(s) are now considered invalid, instead
2364 of the number of bytes specified by the start byte.
2365 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2366 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2367 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2368 Previous versions returned a single u'\ufffd'.
2369
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002370- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002371 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2372 arises from the "Overriding __eq__ blocks inheritance ..." warning
2373 when turned into an exception: in this case the exception simply
2374 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002375
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002376- Issue #8748: Fix two issues with comparisons between complex and integer
2377 objects. (1) The comparison could incorrectly return True in some cases
2378 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2379 (2) The comparison raised an OverflowError for large integers, leading
2380 to unpredictable exceptions when combining integers and complex objects
2381 in sets or dicts.
2382
Mark Dickinson81336372010-05-30 12:12:25 +00002383- Issue #5211: Implicit coercion for the complex type is now completely
2384 removed. (Coercion for arithmetic operations was already removed in 2.7
2385 alpha 4, but coercion for rich comparisons was accidentally left in.)
2386
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002387- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2388 and error handler, instead of writing to the C stderr file in utf-8
2389
Georg Brandlfee0f442010-05-22 21:26:21 +00002390- Issue #7902: When using explicit relative import syntax, don't try implicit

2764 with a non-empty format string. This is an effort to future-proof user
2765 code. If a derived class does not currently implement __format__ but later
2766 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002767 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002768 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002829 argument `-` which tells it to read files to compile from stdin. Each line is
2830 read on demand and the named file is compiled immediately. (Original patch by
2831 Piotr Ożarowski).

2841 Fractions instance now raise TypeError instead of returning True/False. This
2842 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2843 <=> complex, and complex <=> complex comparisons.

3206 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3207 returning NULL. The macro now returns a statically allocated empty string

3218 strings,
3219 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3220 numeric strings corresponding to subnormal values,
3221 (3) a memory leak for some values large enough to cause overflow, and
3222 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003253- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003254 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003255 Also, raise ValueError rather than TypeError when an unknown TIPC address
3256 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003260- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003261 file position when calling `truncate()`. It would previously change the file
3262 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003263 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3264

3266 class used to represent files stored inside an archive. The new
3267 implementation is significantly faster and can be wrapped in a
3268 ``io.BufferedReader`` object for more speedups. It also solves an issue
3269 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3270 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003280- Issue #7748: Since unicode values are supported for some metadata options in
3281 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3282 encoded string for them. This ensures that the upload and register commands
3283 send the correct values to PyPI without any error.

3359
Georg Brandlba83f822010-03-14 09:50:54 +00003360- The ``__complex__()`` method is now looked up on the class of instances to
3361 make it consistent with other special methods.

3365
Mark Dickinson1b34d252010-01-01 17:27:30 +00003366- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003367 DeprecationWarning when passed a float argument where an integer was expected.
3368 These functions and methods now raise TypeError instead. The majority of the
3369 effects of this change are in the extension modules, but some core functions
3370 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3371 and many unicode/str methods.

3385 of integers: the result of a/b is now correctly rounded for ints a and b (at
3386 least on IEEE 754 platforms), and in particular does not depend on the
3387 internal representation of a long.

3395
Georg Brandlba83f822010-03-14 09:50:54 +00003396 These executables now work properly with the arch(1) command: ``arch -ppc
3397 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003554- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3555 decimal string that's guaranteed to round back to x under correct rounding
3556 (with round-half-to-even rounding mode). Previously it gave a string based on
3557 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3558 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3559 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003561- Issue #7117: On almost all platforms: float-to-string and string-to-float
3562 conversions within Python are now correctly rounded. Places these conversions
3563 occur include: str for floats and complex numbers; the float and complex
3564 constructors; old-style and new-style numeric formatting; serialization and
3565 deserialization of floats and complex numbers using marshal, pickle and json;
3566 parsing of float and imaginary literals in Python code; Decimal-to-float
3567 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003568
Georg Brandlba83f822010-03-14 09:50:54 +00003569 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3570 providing correctly-rounded strtod and dtoa C functions. This code is
3571 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3572 the C compiler. There may be a small number of platforms on which correct
3573 operation of this code cannot be guaranteed, so the code is not used: notably,
3574 this applies to platforms where the C double format is not IEEE 754 binary64,
3575 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3576 and Python's configure script is unable to determine how to change the FPU
3577 precision. On these platforms conversions use the platform strtod and dtoa,
3578 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003580- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3581 uses the correctly-rounded string <-> float conversions described above (when
3582 available), and so produces correctly rounded results that will display nicely
3583 under the float repr. There are two related small changes: (1) round now
3584 accepts any class with an ``__index__()`` method for its second argument (but
3585 no longer accepts floats for the second argument), and (2) an excessively
3586 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3587 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005152- Issue #6561: '\d' in a regex now matches only characters with Unicode category
5153 'Nd' (Number, Decimal Digit). Previously it also matched characters with
5154 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00005155
Georg Brandlba83f822010-03-14 09:50:54 +00005156- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
5157 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
5158 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00005159
Georg Brandlba83f822010-03-14 09:50:54 +00005160- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

5162 '<', '>'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005163
Georg Brandlba83f822010-03-14 09:50:54 +00005164 - Packing a float now always gives a Deprecation Warning. Previously it
5165 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005166
Georg Brandlba83f822010-03-14 09:50:54 +00005167 - If x is not an int, long or float, then packing x will always result in
5168 struct.error. Previously an x with an __int__ method could be packed by
5169 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5170 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5171 neither __int__ nor __long__, TypeError used to be raised (with a
5172 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5173 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005174
Georg Brandlba83f822010-03-14 09:50:54 +00005175 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5176 argument with an __int__ method can be packed, but use of this feature
5177 triggers a DeprecationWarning.

5185 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00005186 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00005210- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
5211 in the Lib/test directory, which might be read-only for the user running the
5212 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00005213
Georg Brandlba83f822010-03-14 09:50:54 +00005214- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
5215 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00005216
Georg Brandlba83f822010-03-14 09:50:54 +00005217- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
5218 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00005219
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00005220- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00005222- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
5223 primitives such as Lock, RLock, Condition, Event and Semaphore.
5224
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005225- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00005226 leak-chasing test runs give sensible results. The previous method of reaping
5227 threads could return successfully while some Thread objects were still
5228 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005229
Georg Brandlba83f822010-03-14 09:50:54 +00005230- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
5231 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00005232
Antoine Pitrou58d2f262009-10-10 20:52:11 +00005233- Issue #7055: test___all__ now greedily detects all modules which have an
5234 __all__ attribute, rather than using a hardcoded and incomplete list.
5235
R. David Murray14dcd432009-10-14 13:58:07 +00005236- Issue #7058: Added save/restore for things like sys.argv and cwd to
5237 runtest_inner in regrtest, with warnings if the called test modifies them,
5238 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00005239
Mark Dickinson245d9152009-10-04 18:38:39 +00005240- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

5243 off the trailing 0 in the version number.
5244
Guilherme Polo7f146ab2009-06-21 17:22:50 +00005245- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5246 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005247 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5248 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00005249
Antoine Pitrou4698d992009-05-31 14:20:14 +00005250- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5251 regression tests in parallel, shortening the total runtime.
5252
Georg Brandlba83f822010-03-14 09:50:54 +00005253- Issue #5354: New test support function import_fresh_module() makes it easy to
5254 import both normal and optimised versions of modules. test_heapq and
5255 test_warnings have been adjusted to use it, tests for other modules with both
5256 C and Python implementations in the stdlib can be adjusted to use it over
5257 time.

5264
Georg Brandlba83f822010-03-14 09:50:54 +00005265- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5266 should cause a test to be skipped are now done using import_module from test
5267 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00005268
Guilherme Polob1a98de2009-01-28 20:03:26 +00005269- Issue #5083: New 'gui' resource for regrtest.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005370- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5371 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5372 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5373 ``printf`` function, whereas PyString_FromFormat has an independent
5374 implementation and uses "%zd" on all platforms for size_t values.
5375 This makes a difference on win64, where ``printf`` needs "%Id" to display
5376 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005378- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005391- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005392 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005393 was correctly parsed but parsing of subsequent arguments failed.
5394
Vinay Sajip35e3b032008-09-01 14:33:59 +00005395- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005396 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5397 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5398 when given a tuple of classes as second argument, were looking up
5399 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5400 type object.
5401
Neal Norwitz18aa3882008-08-24 05:04:52 +00005402- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005471 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5472 for catch_warnings() also led to an improvement in the raising of a
5473 DeprecationWarning related to warnings.warn_explicit().
5474

5501
Benjamin Peterson37346b22008-08-23 20:27:43 +00005502- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005539What's New in Python 2.6 beta 3?
5540================================
5541
Barry Warsaw07a4a382008-08-21 01:15:08 +00005542*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005543
5544Core and Builtins
5545-----------------
5546
Guido van Rossumf8402962008-08-20 15:01:50 +00005547- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5548 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5549 extensions do not automatically benefit from the class attribute
5550 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5551 to their tp_flags field if they care. This is a backwards
5552 compatibility feature; in 3.0, all types will use the cache by
5553 default.
5554
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005555- Keyword arguments can now follow starred arguments. (``f(a, *args,
5556 keyword=23)`` is now valid syntax.)
5557
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005558- ctypes function pointers that are COM methods have a boolean True
5559 value again.
5560
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005561- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5562 by denying s# to parse objects that have a releasebuffer procedure,
5563 and introducing s*.
5564
Georg Brandl1e13ea92008-08-11 09:07:59 +00005565- Issue #3537: Fix an assertion failure when an empty but presized dict
5566 object was stored in the freelist.
5567
Mark Dickinsonb6467572008-08-04 21:30:09 +00005568- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5569 ValueError consistently across platforms.
5570
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005571- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5572 (64bit Unix, for example), unichr() would truncate its argument and return
5573 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5574
Neal Norwitze7d8be82008-07-31 17:17:14 +00005575- Apply security patches from Apple.
5576
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005577- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5578 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5579
Antoine Pitrou92f82162008-07-25 22:22:08 +00005580- Issue #1819: function calls with several named parameters are now on
5581 average 35% faster (as measured by pybench).
5582
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005583- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5584 the python debugger steps into a class statement: the free variables (local
5585 variables defined in an outer scope) would be deleted from the outer scope.
5586
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005587- Issue #2620: Overflow checking when allocating or reallocating memory
5588 was not always being done properly in some python types and extension
5589 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5590 all been updated to perform better checks and places in the code that
5591 would previously leak memory on the error path when such an allocation
5592 failed have been fixed.

5595-------
5596
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005597- Issue #3612: Added some missing basic types in ctypes.wintypes.
5598
Benjamin Petersone977ad42008-08-20 01:42:01 +00005599- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5600 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5601
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005602- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5603 version reported by these tools does not necessarily follow the python
5604 version numbering scheme, so the module is less strict when parsing it.
5605
Nick Coghlanf70385a2008-08-18 12:42:46 +00005606- Issue #2235: Added Py3k warnings for types which will become unhashable
5607 under the stricter __hash__ inheritance rules in 3.0. Several types
5608 which did not meet the rules for hash invariants and were already
5609 unhashable in 3.0 have now been explicitly flagged as unhashable in
5610 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5611 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5612
Brett Cannon88f801d2008-08-18 00:46:22 +00005613- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5614 imported into the module but exposed as part of the module's API.
5615
Brett Cannon7b96f072008-08-18 00:41:11 +00005616- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5617
Brett Cannon46225e72008-08-18 00:36:52 +00005618- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005620- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5621
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005622- Issue #3575: Incremental decoder's decode function now takes bytearray
5623 by using 's*' instead of 't#'.
5624
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005625- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005626 fails unicode conversion on 2nd parameter. (windows only)
5627
Georg Brandl222e2082010-08-01 22:27:39 +00005628- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005629 in a redirect.
5630
Brett Cannonabe423e2008-08-16 21:47:07 +00005631- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005632 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005633
Facundo Batistaeb90b782008-08-16 14:44:07 +00005634- Issue #2776: fixed small issue when handling an URL with double slash
5635 after a 302 response in the case of not going through a proxy.
5636
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005637- Issue #2676: in the email package, content-type parsing was hanging on
5638 pathological input because of quadratic or exponential behaviour of a
5639 regular expression.
5640
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005641- Issue #3476: binary buffered reading through the new "io" library is now
5642 thread-safe.
5643
Brett Cannonbf3157b2008-08-14 05:00:03 +00005644- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5645 since mimetools itself is deprecated. Because modules are cached, all
5646 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5647
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005648- Issue #3134: shutil referenced undefined WindowsError symbol.
5649
Robert Schuppenies14646332008-08-10 11:01:53 +00005650- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5651 menu entries were not deleted.
5652
Brett Cannon83e81842008-08-09 23:30:55 +00005653- Copied the implementation of reduce() to _functools.reduce() to have a
5654 version that did not raise a DeprecationWarning under -3.
5655
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005656- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5657 a MemoryError rather than silently stop the iteration.
5658
Guido van Rossum59ce9012008-08-09 14:55:34 +00005659- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5660 to _sre.compile() will now be rejected. This should not affect anybody
5661 since the re.compile() function never generates invalid re-bytecode.
5662
Skip Montanaroa032bf42008-08-08 22:52:51 +00005663- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5664 upon first access it can be automatically initialized from the csv file if
5665 it wasn't initialized during instantiation.
5666
Brett Cannon3aa2a492008-08-06 22:28:09 +00005667- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5668 the reload() built-in has been removed.
5669
Brett Cannon7e30b672008-08-04 21:52:25 +00005670- Changed code in the following modules/packages to remove warnings raised

5739-----------------
5740
Georg Brandl3e483f62008-07-16 22:57:41 +00005741- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5742 its methods now allow for items objects that can be converted to
5743 an integer using operator.index().
5744
Mark Dickinson64b7e502008-07-16 09:40:03 +00005745- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5746 produced a ValueError instead of giving the correct float.
5747
Eric Smitha5fa5a22008-07-16 00:11:49 +00005748- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5749 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5750
Mark Dickinson7103aa42008-07-15 19:08:33 +00005751- Issue #3008: the float type has a new instance method 'float.hex'
5752 and a new class method 'float.fromhex' to convert floating-point
5753 numbers to and from hexadecimal strings, respectively.
5754
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005755- Issue #2235: __hash__ is once again inherited by default. To allow
5756 collections.Hashable to remain meaningful in the presence of the
5757 default hash implementation (object.__hash__), it is now possible
5758 to explicit block inheritance of hash by setting __hash__=None at
5759 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5760 level.
5761
Nick Coghlanb028f502008-07-13 14:52:36 +00005762- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5763 the parent module cannot be found while performing an absolute import.
5764 This means that an incorrectly defined __package__ attribute will
5765 now only prevent relative imports in that module rather than causing
5766 all imports from that module to fail.
5767
Nick Coghlan14ff9942008-07-08 14:21:42 +00005768- Issue #2517: Allow unicode messages in Exceptions again by correctly

5778 another thread's dictionary.
5779
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005780- Issue #3004: Minor change to slice.indices(): the start and stop
5781 arguments are now treated identically, making the behaviour easier
5782 to describe and understand. For example, slice(None, -10,
5783 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5784 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5785 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00005787- Issue #3219: Calling a function with repeated keyword arguments,

5828 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005829 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005830 content-length. The problem had been corrected in the 2.4 branch, but never
5831 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005846- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006237- On MacOS X it is now possible to install the framework in 64-bit
6238 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006239 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006240
6241 This is controlled by the configure argument ``--with-universal-archs``:
6242
6243 - ``--with-universal-archs=all``: install 4-way universal
6244
6245 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6246
6247 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6248
6249 This option should be used in combination with ``--enable-universalsdk=``.
6250
6251 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6256
Georg Brandl74a1dea2008-05-28 11:21:39 +00006257- Add ``PyType_Modified()`` as a public API to clear the type cache.
6258
6259- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006260
6261- The PyString functions have been renamed to PyBytes. A batch of
6262 defines were added so that the linker still sees the original
6263 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006301- Issue #1631171: Re-implement the 'warnings' module in C (the
6302 original Python code has been kept as backup). This will allow for
6303 using the 'warning's machinery in such places as the parser where
6304 use of pure Python code is not possible. Both the ``showarning()``
6305 and ``formatwarning()`` gain an optional 'line' argument which is
6306 not called by default for backwards-compatibility reasons. Setting
6307 ``warnings.showwarning()`` to an implementation that lacks support
6308 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006333- The getpass module has been improved on Unix. It now uses /dev/tty
6334 by default and uses stderr instead of stdout. A GetPassWarning is
6335 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006350- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006351 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006371- Issue #2550: The approach used by client/server code for obtaining
6372 ports to listen on in network-oriented tests has been refined in an
6373 effort to facilitate running multiple instances of the entire
6374 regression test suite in parallel without issue.
6375 test_support.bind_port() has been fixed such that it will always
6376 return a unique port -- which wasn't always the case with the
6377 previous implementation, especially if socket options had been set
6378 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6379 new implementation of bind_port() will actually raise an exception
6380 if it is passed an AF_INET/SOCK_STREAM socket with either the
6381 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6382 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6383 the socket it's been passed. This currently only applies to
6384 Windows. This option prevents any other sockets from binding to the
6385 host/port we've bound to, thus removing the possibility of the
6386 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6387 when a second SOCK_STREAM socket binds and accepts to a host/port
6388 that's already been bound by another socket. The optional preferred
6389 port parameter to bind_port() has been removed. Under no
6390 circumstances should tests be hard coding ports!
6391
6392 test_support.find_unused_port() has also been introduced, which will
6393 pass a temporary socket object to bind_port() in order to obtain an
6394 unused port. The temporary socket object is then closed and
6395 deleted, and the port is returned. This method should only be used
6396 for obtaining an unused port in order to pass to an external program
6397 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6398 a parameter to a server-oriented class that doesn't give you direct
6399 access to the underlying socket used.
6400
6401 Finally, test_support.HOST has been introduced, which should be used
6402 for the host argument of any relevant socket calls (i.e. bind and
6403 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006404
6405 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006407 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6408 test_asynchat and test_socket_ssl.
6409
Georg Brandl3ee81df2008-05-17 18:14:43 +00006410 It is now possible for multiple instances of the regression test
6411 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006690- Added the future_builtins module, which contains hex() and oct().
6691 These are the PEP 3127 version of these functions, designed to be
6692 compatible with the hex() and oct() builtins from Python 3.0. They
6693 differ slightly in their output formats from the existing, unchanged
6694 Python 2.6 builtins. The expected usage of the future_builtins
6695 module is:
6696 from future_builtins import hex, oct
6697
Eric Smith7ef40bf2008-02-20 23:34:22 +00006698- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6699 exponents for exponents with absolute value < 100. Follows C99
6700 standard. This is a change on Windows, which would use 3 digits.
6701 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6702 so that any alterations it does to the resulting string will be
6703 available in stringlib/formatter.h (for float.__format__).
6704
Eric Smith5a3c1352008-02-19 13:21:56 +00006705- Implemented PEP 3101, Advanced String Formatting. This adds a new
6706 builtin format(); a format() method for str and unicode; a
6707 __format__() method to object, str, unicode, int, long, float, and
6708 datetime; the class string.Formatter; and the C API
6709 PyObject_Format().
6710
Georg Brandl3ee81df2008-05-17 18:14:43 +00006711- Fixed several potential crashes, all caused by specially crafted
6712 __del__ methods exploiting objects in temporarily inconsistent
6713 state.

6724 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006725
Georg Brandl3ee81df2008-05-17 18:14:43 +00006726- Issue #2045: Fix an infinite recursion triggered when printing a
6727 subclass of collections.defaultdict, if its default_factory is set
6728 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006729
Christian Heimesf75dbef2008-02-08 00:11:31 +00006730- Fixed a minor memory leak in dictobject.c. The content of the free
6731 list was not freed on interpreter shutdown.
6732
Georg Brandl21e99f42010-03-07 15:23:59 +00006733- Limit free list of method and built-in function objects to 256

6737 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006738 to compact the internal free lists of pre-allocted ints and floats.
6739
Georg Brandl3ee81df2008-05-17 18:14:43 +00006740- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6741 calls. Python expected the return type int but the fork familie
6742 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006753- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6754 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006755
Georg Brandl3ee81df2008-05-17 18:14:43 +00006756- Patch #1473257: generator objects gain a gi_code attribute. This is
6757 the same object as the func_code attribute of the function that
6758 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006759
Georg Brandl3ee81df2008-05-17 18:14:43 +00006760- Issue #1920: "while 0" statements were completely removed by the
6761 compiler, even in the presence of an "else" clause, which is
6762 supposed to be run when the condition is false. Now the compiler
6763 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006764
Guido van Rossumeead05f2008-01-24 18:21:02 +00006765- A few crashers fixed: weakref_in_del.py (issue #1377858);
6766 loosing_dict_ref.py (issue #1303614, test67.py);
6767 borrowed_ref_[34].py (not in tracker).
6768
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006769- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006770 suppressed while an extension is loaded by calling SetErrorMode in
6771 dynload_win.c. The error is still reported properly.
6772
Georg Brandl3ee81df2008-05-17 18:14:43 +00006773- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006774 several extension methods and modules do not work without unicode
6775 support.
6776
Georg Brandl26543b12008-01-21 18:36:51 +00006777- Issue #1882: when compiling code from a string, encoding cookies in the
6778 second line of code were not always recognized correctly.
6779
Georg Brandl14404b62008-01-19 19:27:05 +00006780- Issue #1679: "0x" was taken as a valid integer literal.
6781
Georg Brandl6caad7d2008-01-26 14:19:22 +00006782- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006783 added.
6784
Christian Heimesc94e2b52008-01-14 04:13:37 +00006785- sys.float_info / PyFloat_GetInfo: The floating point information
6786 object was converted from a dict to a specialized structseq object.
6787
Georg Brandl3ee81df2008-05-17 18:14:43 +00006788- Patch #1816: Added sys.flags structseq. It exposes the status of
6789 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006790
Georg Brandl3ee81df2008-05-17 18:14:43 +00006791- Objects/structseq.c: Implemented new structseq representation. The
6792 patch makes structseqs (e.g. the return value of os.stat) more
6793 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006794
Georg Brandl3ee81df2008-05-17 18:14:43 +00006795- Patch #1700288: added a type attribute cache that caches method
6796 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006797
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006798- Bug #1776: __import__() no longer accepts filenames on any platform.
6799 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006800
Georg Brandlaed6c662008-01-07 17:25:53 +00006801- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6804 envvar and sys.dont_write_bytecode attribute. All these can be set
6805 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006806
Georg Brandl3ee81df2008-05-17 18:14:43 +00006807- Improve some exception messages when Windows fails to load an
6808 extension module. Now we get for example '%1 is not a valid Win32
6809 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6814 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006815
Christian Heimes0a8143f2007-12-18 23:22:54 +00006816- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006817 and INF. float("nan"), float("inf") and float("-inf") now work on
6818 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006819
Georg Brandl3ee81df2008-05-17 18:14:43 +00006820- Compiler now generates simpler and faster code for dictionary
6821 literals. The oparg for BUILD_MAP now indicates an estimated
6822 dictionary size. There is a new opcode, STORE_MAP, for adding
6823 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006826
Georg Brandl3ee81df2008-05-17 18:14:43 +00006827- Issue #1620: New property decorator syntax was modifying the
6828 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006829
Georg Brandl3ee81df2008-05-17 18:14:43 +00006830- Issue #1538: Avoid copying string in split/rsplit if the split char
6831 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006832
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006833- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006834 SystemError.
6835
Nick Coghlanef01d822007-12-03 12:55:17 +00006836- PEP 366: Allow explicit relative imports when executing modules
6837 inside packages with the -m switch via a new module level
6838 __package__ attribute.
6839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Issue #1402: Fix a crash on exit, when another thread is still
6841 running, and if the deallocation of its frames somehow calls the
6842 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006843

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006847 attribute of an empty cell object.
6848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Issue #1460: The utf-7 incremental decoder did not accept truncated
6850 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006851
Georg Brandl3ee81df2008-05-17 18:14:43 +00006852- Patch #1739468: Directories and zipfiles containing a __main__.py
6853 file can now be directly executed by passing their name to the
6854 interpreter. The directory/zipfile is automatically inserted as the
6855 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006856
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Issue #1265: Fix a problem with sys.settrace, if the tracing
6858 function uses a generator expression when at the same time the
6859 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006860
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006861- sets and frozensets now have an isdisjoint() method.
6862
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006863- optimize the performance of builtin.sum().
6864
Neal Norwitz44f326e2007-10-05 05:29:17 +00006865- Fix warnings found by the new version of the Coverity checker.
6866
Georg Brandl21e99f42010-03-07 15:23:59 +00006867- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006868 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6869 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006870
Georg Brandl3ee81df2008-05-17 18:14:43 +00006871- Issue #1686386: Tuple's tp_repr did not take into account the
6872 possibility of having a self-referential tuple, which is possible
6873 from C code. Nor did object's tp_str consider that a type's tp_str
6874 could do something that could lead to an inifinite recursion.
6875 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6876 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006877
Georg Brandl3ee81df2008-05-17 18:14:43 +00006878- Issue #1164: It was possible to trigger deadlock when using the
6879 'print' statement to write to a file since the GIL was not released
6880 as needed. Now PyObject_Print() does the right thing along with
6881 various tp_print implementations of the built-in types and those in
6882 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006883
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884- Issue #1147: Exceptions were directly allowing string exceptions in
6885 their throw() method even though string exceptions no longer
6886 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006887
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888- Issue #1096: Prevent a segfault from getting the repr of a very
6889 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006890
Brett Cannon1e534b52007-09-07 04:18:30 +00006891- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006892 PyObject_Call() never calling back out to Python code to trigger
6893 recursion depth updates/checks. Required the creation of a static
6894 RuntimeError instance in case normalizing an exception put the
6895 recursion check value past its limit. Fixes crashers
6896 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006897
Georg Brandl3ee81df2008-05-17 18:14:43 +00006898- Patch #1031213: Decode source line in SyntaxErrors back to its
6899 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00006901- Patch #1673759: add a missing overflow check when formatting floats
6902 with %G.
6903
Georg Brandl3ee81df2008-05-17 18:14:43 +00006904- Prevent expandtabs() on string and unicode objects from causing a
6905 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006906

Georg Brandla5ea6892007-06-01 11:33:33 +00006910
Neal Norwitz0ac60192007-05-27 04:08:54 +00006911- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006912 __*__ attributes. (Some already existed, e.g., __doc__ and
6913 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006914
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006915- Add -3 option to the interpreter to warn about features that are
6916 deprecated and will be changed/removed in Python 3.0.
6917
Georg Brandl2134e752007-05-21 20:34:16 +00006918- Patch #1686487: you can now pass any mapping after '**' in function
6919 calls.
6920
Collin Winter62903052007-05-18 23:11:24 +00006921- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006922 "except E as target:". This is to provide forwards compatibility
6923 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006924
Brett Cannon229cee22007-05-05 01:34:02 +00006925- Deprecate BaseException.message as per PEP 352.
6926
Georg Brandl3ee81df2008-05-17 18:14:43 +00006927- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006928 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006929
Vinay Sajip8549ce32007-05-06 17:53:37 +00006930- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006931 setting a plain string, ie don't expand to single letter identifiers.
6932
Raymond Hettinger13936692007-04-11 18:40:58 +00006933- Request #1191699: Slices can now be pickled.
6934
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006935- Request #1193128: str.translate() now allows a None argument for
6936 translations that only remove characters without re-mapping the
6937 remaining characters.
6938
Georg Brandl5cb76c12007-03-21 09:00:39 +00006939- Patch #1682205: a TypeError while unpacking an iterable is no longer
6940 masked by a generic one with the message "unpack non-sequence".
6941
Neal Norwitzaa754b72007-03-21 06:39:48 +00006942- Remove unused file Python/fmod.c.
6943
Guido van Rossum143b5642007-03-23 04:58:42 +00006944- Bug #1683368: The object.__init__() and object.__new__() methods are
6945 now stricter in rejecting excess arguments. The only time when
6946 either allows excess arguments is when it is not overridden and the
6947 other one is. For backwards compatibility, when both are
6948 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006949 warning later). Also, type.__init__() insists on the same signature
6950 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006951
Georg Brandl3ee81df2008-05-17 18:14:43 +00006952- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6953 object to complex using its __complex__() method before falling back
6954 to the __float__() method. Therefore, the functions in the cmath
6955 module now can operate on objects that define a __complex__()
6956 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006957
Georg Brandl3ee81df2008-05-17 18:14:43 +00006958- Patch #1623563: allow __class__ assignment for classes with
6959 __slots__. The old and the new class are still required to have the
6960 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006961
Georg Brandl3ee81df2008-05-17 18:14:43 +00006962- Patch #1642547: Fix an error/crash when encountering syntax errors
6963 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006965- Patch #1462488: Python no longer segfaults when
6966 ``object.__reduce_ex__()`` is called with an object that is faking
6967 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006968
Georg Brandl3ee81df2008-05-17 18:14:43 +00006969- Patch #1680015: Don't modify __slots__ tuple if it contains an
6970 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00006972- Patch #1444529: the builtin compile() now accepts keyword arguments.
6973
Georg Brandl7b9c5552007-03-12 14:30:05 +00006974- Bug #1678647: write a newline after printing an exception in any
6975 case, even when converting the value to a string failed.
6976
Georg Brandl871f1bc2007-03-12 13:17:36 +00006977- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006978 its argument, if it exists. If not, it will work like before. This
6979 allows customizing the output of dir() in the presence of a
6980 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006981
Collin Winter276887b2007-03-12 16:11:39 +00006982- Patch #922167: Python no longer segfaults when faced with infinitely
6983 self-recursive reload() calls (as reported by bug #742342).
6984
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985- Patch #1675981: remove unreachable code from ``type.__new__()``
6986 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006987
Georg Brandl3ee81df2008-05-17 18:14:43 +00006988- Patch #1491866: change the complex() constructor to allow
6989 parthensized forms. This means complex(repr(x)) now works instead of
6990 raising a ValueError.

7501 ".cpp" too.
7502
Facundo Batistad918a652007-04-24 13:54:38 +00007503- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504 the client's request was successfully received, understood, and
7505 accepted. Now in these cases no error is raised in urllib (issue
7506 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007507

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007514- Added a timeout parameter to the constructor of other protocols
7515 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7516 work started with create_connection() and timeout in httplib, and
7517 closes patch #723312.
7518
Vinay Sajip8549ce32007-05-06 17:53:37 +00007519- Patch #1676823: Added create_connection() to socket.py, which may be
7520 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007521 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007522
Martin v. Löwis0af33882007-03-23 13:27:15 +00007523- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007530- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
7531 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00007532 directories.
7533

7535 GNOME or KDE browser, depending on whether there is a session of one
7536 of those present. Also, it tries the Windows default browser before
7537 trying Mozilla variants.

7543
Georg Brandlf66b6032007-03-14 08:27:52 +00007544- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007545 AttributeError instead of an IOError when the server's response
7546 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007547
Georg Brandl3ee81df2008-05-17 18:14:43 +00007548- Patch #957650: "%var%" environment variable references are now
7549 properly expanded in ntpath.expandvars(), also "~user" home
7550 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00007551
Georg Brandl3ee81df2008-05-17 18:14:43 +00007552- Patch #1429539: pdb now correctly initializes the __main__ module
7553 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007554 correctly now.
7555
Georg Brandlbad6f192007-03-13 21:32:56 +00007556- The nonobvious commands.getstatus() function is now deprecated.

7562
Georg Brandl3ee81df2008-05-17 18:14:43 +00007563- Patch #1530482: add pydoc.render_doc() which returns the
7564 documentation for a thing instead of paging it to stdout, which
7565 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007566
Georg Brandl3ee81df2008-05-17 18:14:43 +00007567- Patch #1533909: the timeit module now accepts callables in addition

7573 parameter which can be set to False to prevent the default
7574 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007575
Georg Brandl9e6b4702007-03-13 18:15:41 +00007576- Patch #1581073: add a flag to textwrap that prevents the dropping of
7577 whitespace while wrapping.
7578
Georg Brandl92a6bae2007-03-13 17:43:32 +00007579- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007580 are set for invalid interpolation sequences that would lead to
7581 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007582

7595
Georg Brandl94fe3f52007-03-13 09:32:11 +00007596- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007597 field names in its exception message if you try to write a record
7598 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007616

7624 returned string up to the first NUL character.
7625

7635
Georg Brandl3ee81df2008-05-17 18:14:43 +00007636- unittest now verifies more of its assumptions. In particular,
7637 TestCase and TestSuite subclasses (not instances) are no longer
7638 accepted in TestSuite.addTest(). This should cause no
7639 incompatibility since it never made sense with ordinary subclasses
7640 -- the failure just occurred later, with a more cumbersome
7641 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007642

7650 given a unicode argument and os.listdir() returns unicode filenames.
7651
Georg Brandl3ee81df2008-05-17 18:14:43 +00007652- Patch #1673619: setup.py identifies extension modules it doesn't

7654 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008030 time so that opening a database previously created with the DB_DUP
8031 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8032 opens. Specifically: dictionary assignment to a DB object will
8033 replace all values for a given key when the database allows
8034 duplicate values. DB users should use DB.put(k, v) when they want
8035 to store duplicates; not DB[k] = v.

8042 characters with ASCII value less than 32. Also, it correctly quotes
8043 dots only if they occur on a single line, as opposed to the previous
8044 behavior of quoting dots if they are the second character of any
8045 line.
