Florent Xiclunac2279652012-02-12 14:49:03 +0100622- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100623 has left two versions of customize_compiler, the original in
624 distutils.sysconfig and another copy in distutils.ccompiler, with some
625 parts of distutils calling one and others using the other.

627 is the case in 3.x.
628
Ned Deily0d0ea482012-02-10 12:59:06 +0100629- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
630 Distutils-based packages with C extension modules may fail because
631 Apple has removed gcc-4.2, the version used to build python.org
632 64-bit/32-bit Pythons. If the user does not explicitly override
633 the default C compiler by setting the CC environment variable,
634 Distutils will now attempt to compile extension modules with clang
635 if gcc-4.2 is required but not found. Also as a convenience, if
636 the user does explicitly set CC, substitute its value as the default
637 compiler in the Distutils LDSHARED configuration variable for OS X.
638 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
639 SDK, neither of which are available in Xcode 4. This change does not
640 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700913- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
914 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
915 interpreter process. This could cause failures in non-Distutils subprocesses
916 and was unreliable since tests or user programs could modify the interpreter
917 environment after Distutils set it. Instead, have Distutils set the the
918 deployment target only in the environment of each build subprocess. It is
919 still possible to globally override the default by setting
920 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
921 greater or equal to the default value, the value with which the interpreter
922 was built.

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

1907 This prevents user-created self-referencing ordered dictionaries from
1908 becoming permanently uncollectable GC garbage. The downside is that

2368-----------------
2369
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002370- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2371 start byte and the continuation byte(s) are now considered invalid, instead
2372 of the number of bytes specified by the start byte.
2373 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2374 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2375 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2376 Previous versions returned a single u'\ufffd'.
2377
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002378- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002379 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2380 arises from the "Overriding __eq__ blocks inheritance ..." warning
2381 when turned into an exception: in this case the exception simply
2382 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002383
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002384- Issue #8748: Fix two issues with comparisons between complex and integer
2385 objects. (1) The comparison could incorrectly return True in some cases
2386 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2387 (2) The comparison raised an OverflowError for large integers, leading
2388 to unpredictable exceptions when combining integers and complex objects
2389 in sets or dicts.
2390
Mark Dickinson81336372010-05-30 12:12:25 +00002391- Issue #5211: Implicit coercion for the complex type is now completely
2392 removed. (Coercion for arithmetic operations was already removed in 2.7
2393 alpha 4, but coercion for rich comparisons was accidentally left in.)
2394
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002395- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2396 and error handler, instead of writing to the C stderr file in utf-8
2397
Georg Brandlfee0f442010-05-22 21:26:21 +00002398- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00002771- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2772 with a non-empty format string. This is an effort to future-proof user
2773 code. If a derived class does not currently implement __format__ but later
2774 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002775 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002776 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002836- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002837 argument `-` which tells it to read files to compile from stdin. Each line is
2838 read on demand and the named file is compiled immediately. (Original patch by

3214 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3215 returning NULL. The macro now returns a statically allocated empty string

3226 strings,
3227 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3228 numeric strings corresponding to subnormal values,
3229 (3) a memory leak for some values large enough to cause overflow, and
3230 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003261- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003262 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003263 Also, raise ValueError rather than TypeError when an unknown TIPC address
3264 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003268- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003269 file position when calling `truncate()`. It would previously change the file
3270 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003271 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3272
Georg Brandlba83f822010-03-14 09:50:54 +00003273- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3274 class used to represent files stored inside an archive. The new
3275 implementation is significantly faster and can be wrapped in a
3276 ``io.BufferedReader`` object for more speedups. It also solves an issue
3277 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3278 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003288- Issue #7748: Since unicode values are supported for some metadata options in
3289 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3290 encoded string for them. This ensures that the upload and register commands
3291 send the correct values to PyPI without any error.

3367
Georg Brandlba83f822010-03-14 09:50:54 +00003368- The ``__complex__()`` method is now looked up on the class of instances to
3369 make it consistent with other special methods.

3373
Mark Dickinson1b34d252010-01-01 17:27:30 +00003374- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003375 DeprecationWarning when passed a float argument where an integer was expected.
3376 These functions and methods now raise TypeError instead. The majority of the
3377 effects of this change are in the extension modules, but some core functions
3378 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3379 and many unicode/str methods.

3393 of integers: the result of a/b is now correctly rounded for ints a and b (at
3394 least on IEEE 754 platforms), and in particular does not depend on the
3395 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003404 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003562- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3563 decimal string that's guaranteed to round back to x under correct rounding
3564 (with round-half-to-even rounding mode). Previously it gave a string based on
3565 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3566 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3567 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003569- Issue #7117: On almost all platforms: float-to-string and string-to-float
3570 conversions within Python are now correctly rounded. Places these conversions
3571 occur include: str for floats and complex numbers; the float and complex
3572 constructors; old-style and new-style numeric formatting; serialization and
3573 deserialization of floats and complex numbers using marshal, pickle and json;
3574 parsing of float and imaginary literals in Python code; Decimal-to-float
3575 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003576
Georg Brandlba83f822010-03-14 09:50:54 +00003577 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3578 providing correctly-rounded strtod and dtoa C functions. This code is
3579 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3580 the C compiler. There may be a small number of platforms on which correct
3581 operation of this code cannot be guaranteed, so the code is not used: notably,
3582 this applies to platforms where the C double format is not IEEE 754 binary64,
3583 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3584 and Python's configure script is unable to determine how to change the FPU
3585 precision. On these platforms conversions use the platform strtod and dtoa,
3586 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003588- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3589 uses the correctly-rounded string <-> float conversions described above (when
3590 available), and so produces correctly rounded results that will display nicely
3591 under the float repr. There are two related small changes: (1) round now
3592 accepts any class with an ``__index__()`` method for its second argument (but
3593 no longer accepts floats for the second argument), and (2) an excessively
3594 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3595 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005160- Issue #6561: '\d' in a regex now matches only characters with Unicode category
5161 'Nd' (Number, Decimal Digit). Previously it also matched characters with
5162 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00005163
Georg Brandlba83f822010-03-14 09:50:54 +00005164- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
5165 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
5166 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00005167
Georg Brandlba83f822010-03-14 09:50:54 +00005168- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

5170 '<', '>'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005171
Georg Brandlba83f822010-03-14 09:50:54 +00005172 - Packing a float now always gives a Deprecation Warning. Previously it
5173 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005174
Georg Brandlba83f822010-03-14 09:50:54 +00005175 - If x is not an int, long or float, then packing x will always result in
5176 struct.error. Previously an x with an __int__ method could be packed by
5177 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5178 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5179 neither __int__ nor __long__, TypeError used to be raised (with a
5180 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5181 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005182
Georg Brandlba83f822010-03-14 09:50:54 +00005183 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5184 argument with an __int__ method can be packed, but use of this feature
5185 triggers a DeprecationWarning.

5193 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00005194 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00005218- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
5219 in the Lib/test directory, which might be read-only for the user running the
5220 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00005221
Georg Brandlba83f822010-03-14 09:50:54 +00005222- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
5223 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00005224
Georg Brandlba83f822010-03-14 09:50:54 +00005225- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
5226 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00005227
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00005228- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00005230- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
5231 primitives such as Lock, RLock, Condition, Event and Semaphore.
5232
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005233- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00005234 leak-chasing test runs give sensible results. The previous method of reaping
5235 threads could return successfully while some Thread objects were still
5236 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005237
Georg Brandlba83f822010-03-14 09:50:54 +00005238- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
5239 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00005240
Antoine Pitrou58d2f262009-10-10 20:52:11 +00005241- Issue #7055: test___all__ now greedily detects all modules which have an
5242 __all__ attribute, rather than using a hardcoded and incomplete list.
5243
R. David Murray14dcd432009-10-14 13:58:07 +00005244- Issue #7058: Added save/restore for things like sys.argv and cwd to
5245 runtest_inner in regrtest, with warnings if the called test modifies them,
5246 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00005247
Mark Dickinson245d9152009-10-04 18:38:39 +00005248- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

5251 off the trailing 0 in the version number.
5252
Guilherme Polo7f146ab2009-06-21 17:22:50 +00005253- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5254 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005255 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5256 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00005257
Antoine Pitrou4698d992009-05-31 14:20:14 +00005258- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5259 regression tests in parallel, shortening the total runtime.
5260
Georg Brandlba83f822010-03-14 09:50:54 +00005261- Issue #5354: New test support function import_fresh_module() makes it easy to
5262 import both normal and optimised versions of modules. test_heapq and
5263 test_warnings have been adjusted to use it, tests for other modules with both
5264 C and Python implementations in the stdlib can be adjusted to use it over
5265 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005273- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5274 should cause a test to be skipped are now done using import_module from test
5275 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00005276
Guilherme Polob1a98de2009-01-28 20:03:26 +00005277- Issue #5083: New 'gui' resource for regrtest.

5377
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005378- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5379 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5380 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5381 ``printf`` function, whereas PyString_FromFormat has an independent
5382 implementation and uses "%zd" on all platforms for size_t values.
5383 This makes a difference on win64, where ``printf`` needs "%Id" to display
5384 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005386- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005399- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005400 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005401 was correctly parsed but parsing of subsequent arguments failed.
5402
Vinay Sajip35e3b032008-09-01 14:33:59 +00005403- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005404 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5405 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5406 when given a tuple of classes as second argument, were looking up
5407 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5408 type object.
5409
Neal Norwitz18aa3882008-08-24 05:04:52 +00005410- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005479 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5480 for catch_warnings() also led to an improvement in the raising of a
5481 DeprecationWarning related to warnings.warn_explicit().
5482

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005506- Issue #2975: When compiling several extension modules with Visual Studio 2008
5507 from the same python interpreter, some environment variables would grow
5508 without limit.
5509
Benjamin Peterson37346b22008-08-23 20:27:43 +00005510- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005547What's New in Python 2.6 beta 3?
5548================================
5549
Barry Warsaw07a4a382008-08-21 01:15:08 +00005550*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005551
5552Core and Builtins
5553-----------------
5554
Guido van Rossumf8402962008-08-20 15:01:50 +00005555- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5556 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5557 extensions do not automatically benefit from the class attribute
5558 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5559 to their tp_flags field if they care. This is a backwards
5560 compatibility feature; in 3.0, all types will use the cache by
5561 default.
5562
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005563- Keyword arguments can now follow starred arguments. (``f(a, *args,
5564 keyword=23)`` is now valid syntax.)
5565
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005566- ctypes function pointers that are COM methods have a boolean True
5567 value again.
5568
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005569- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5570 by denying s# to parse objects that have a releasebuffer procedure,
5571 and introducing s*.
5572
Georg Brandl1e13ea92008-08-11 09:07:59 +00005573- Issue #3537: Fix an assertion failure when an empty but presized dict
5574 object was stored in the freelist.
5575
Mark Dickinsonb6467572008-08-04 21:30:09 +00005576- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5577 ValueError consistently across platforms.
5578
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005579- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5580 (64bit Unix, for example), unichr() would truncate its argument and return
5581 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5582
Neal Norwitze7d8be82008-07-31 17:17:14 +00005583- Apply security patches from Apple.
5584
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005585- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5586 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5587
Antoine Pitrou92f82162008-07-25 22:22:08 +00005588- Issue #1819: function calls with several named parameters are now on
5589 average 35% faster (as measured by pybench).
5590
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005591- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5592 the python debugger steps into a class statement: the free variables (local
5593 variables defined in an outer scope) would be deleted from the outer scope.
5594
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005595- Issue #2620: Overflow checking when allocating or reallocating memory
5596 was not always being done properly in some python types and extension
5597 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5598 all been updated to perform better checks and places in the code that
5599 would previously leak memory on the error path when such an allocation
5600 failed have been fixed.

5603-------
5604
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005605- Issue #3612: Added some missing basic types in ctypes.wintypes.
5606
Benjamin Petersone977ad42008-08-20 01:42:01 +00005607- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5608 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5609
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005610- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5611 version reported by these tools does not necessarily follow the python
5612 version numbering scheme, so the module is less strict when parsing it.
5613
Nick Coghlanf70385a2008-08-18 12:42:46 +00005614- Issue #2235: Added Py3k warnings for types which will become unhashable
5615 under the stricter __hash__ inheritance rules in 3.0. Several types
5616 which did not meet the rules for hash invariants and were already
5617 unhashable in 3.0 have now been explicitly flagged as unhashable in
5618 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5619 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5620
Brett Cannon88f801d2008-08-18 00:46:22 +00005621- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5622 imported into the module but exposed as part of the module's API.
5623
Brett Cannon7b96f072008-08-18 00:41:11 +00005624- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5625
Brett Cannon46225e72008-08-18 00:36:52 +00005626- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005628- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5629
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005630- Issue #3575: Incremental decoder's decode function now takes bytearray
5631 by using 's*' instead of 't#'.
5632
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005633- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005634 fails unicode conversion on 2nd parameter. (windows only)
5635
Georg Brandl222e2082010-08-01 22:27:39 +00005636- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005637 in a redirect.
5638
Brett Cannonabe423e2008-08-16 21:47:07 +00005639- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005640 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005641
Facundo Batistaeb90b782008-08-16 14:44:07 +00005642- Issue #2776: fixed small issue when handling an URL with double slash
5643 after a 302 response in the case of not going through a proxy.
5644
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005645- Issue #2676: in the email package, content-type parsing was hanging on
5646 pathological input because of quadratic or exponential behaviour of a
5647 regular expression.
5648
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005649- Issue #3476: binary buffered reading through the new "io" library is now
5650 thread-safe.
5651
Brett Cannonbf3157b2008-08-14 05:00:03 +00005652- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5653 since mimetools itself is deprecated. Because modules are cached, all
5654 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5655
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005656- Issue #3134: shutil referenced undefined WindowsError symbol.
5657
Robert Schuppenies14646332008-08-10 11:01:53 +00005658- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5659 menu entries were not deleted.
5660
Brett Cannon83e81842008-08-09 23:30:55 +00005661- Copied the implementation of reduce() to _functools.reduce() to have a
5662 version that did not raise a DeprecationWarning under -3.
5663
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005664- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5665 a MemoryError rather than silently stop the iteration.
5666
Guido van Rossum59ce9012008-08-09 14:55:34 +00005667- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5668 to _sre.compile() will now be rejected. This should not affect anybody
5669 since the re.compile() function never generates invalid re-bytecode.
5670
Skip Montanaroa032bf42008-08-08 22:52:51 +00005671- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5672 upon first access it can be automatically initialized from the csv file if
5673 it wasn't initialized during instantiation.
5674
Brett Cannon3aa2a492008-08-06 22:28:09 +00005675- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5676 the reload() built-in has been removed.
5677
Brett Cannon7e30b672008-08-04 21:52:25 +00005678- Changed code in the following modules/packages to remove warnings raised

5747-----------------
5748
Georg Brandl3e483f62008-07-16 22:57:41 +00005749- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5750 its methods now allow for items objects that can be converted to
5751 an integer using operator.index().
5752
Mark Dickinson64b7e502008-07-16 09:40:03 +00005753- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5754 produced a ValueError instead of giving the correct float.
5755
Eric Smitha5fa5a22008-07-16 00:11:49 +00005756- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5757 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5758
Mark Dickinson7103aa42008-07-15 19:08:33 +00005759- Issue #3008: the float type has a new instance method 'float.hex'
5760 and a new class method 'float.fromhex' to convert floating-point
5761 numbers to and from hexadecimal strings, respectively.
5762
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005763- Issue #2235: __hash__ is once again inherited by default. To allow
5764 collections.Hashable to remain meaningful in the presence of the
5765 default hash implementation (object.__hash__), it is now possible
5766 to explicit block inheritance of hash by setting __hash__=None at
5767 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5768 level.
5769
Nick Coghlanb028f502008-07-13 14:52:36 +00005770- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5771 the parent module cannot be found while performing an absolute import.
5772 This means that an incorrectly defined __package__ attribute will
5773 now only prevent relative imports in that module rather than causing
5774 all imports from that module to fail.
5775
Nick Coghlan14ff9942008-07-08 14:21:42 +00005776- Issue #2517: Allow unicode messages in Exceptions again by correctly

5786 another thread's dictionary.
5787
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005788- Issue #3004: Minor change to slice.indices(): the start and stop
5789 arguments are now treated identically, making the behaviour easier
5790 to describe and understand. For example, slice(None, -10,
5791 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5792 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5793 10, -1).
5794
Georg Brandl278fc502008-07-19 12:46:12 +00005795- Issue #3219: Calling a function with repeated keyword arguments,
5796 f(a=2, a=23), would not cause a syntax error. This was a regression
5797 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005835- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5836 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005837 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005838 content-length. The problem had been corrected in the 2.4 branch, but never
5839 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005854- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5856
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005857- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006245- On MacOS X it is now possible to install the framework in 64-bit
6246 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006247 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006248
6249 This is controlled by the configure argument ``--with-universal-archs``:
6250
6251 - ``--with-universal-archs=all``: install 4-way universal
6252
6253 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6254
6255 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6256
6257 This option should be used in combination with ``--enable-universalsdk=``.
6258
6259 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6264
Georg Brandl74a1dea2008-05-28 11:21:39 +00006265- Add ``PyType_Modified()`` as a public API to clear the type cache.
6266
6267- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006268
6269- The PyString functions have been renamed to PyBytes. A batch of
6270 defines were added so that the linker still sees the original
6271 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006309- Issue #1631171: Re-implement the 'warnings' module in C (the
6310 original Python code has been kept as backup). This will allow for
6311 using the 'warning's machinery in such places as the parser where
6312 use of pure Python code is not possible. Both the ``showarning()``
6313 and ``formatwarning()`` gain an optional 'line' argument which is
6314 not called by default for backwards-compatibility reasons. Setting
6315 ``warnings.showwarning()`` to an implementation that lacks support
6316 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006341- The getpass module has been improved on Unix. It now uses /dev/tty
6342 by default and uses stderr instead of stdout. A GetPassWarning is
6343 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006358- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006359 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Issue #2550: The approach used by client/server code for obtaining
6380 ports to listen on in network-oriented tests has been refined in an
6381 effort to facilitate running multiple instances of the entire
6382 regression test suite in parallel without issue.
6383 test_support.bind_port() has been fixed such that it will always
6384 return a unique port -- which wasn't always the case with the
6385 previous implementation, especially if socket options had been set
6386 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6387 new implementation of bind_port() will actually raise an exception
6388 if it is passed an AF_INET/SOCK_STREAM socket with either the
6389 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6390 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6391 the socket it's been passed. This currently only applies to
6392 Windows. This option prevents any other sockets from binding to the
6393 host/port we've bound to, thus removing the possibility of the
6394 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6395 when a second SOCK_STREAM socket binds and accepts to a host/port
6396 that's already been bound by another socket. The optional preferred
6397 port parameter to bind_port() has been removed. Under no
6398 circumstances should tests be hard coding ports!
6399
6400 test_support.find_unused_port() has also been introduced, which will
6401 pass a temporary socket object to bind_port() in order to obtain an
6402 unused port. The temporary socket object is then closed and
6403 deleted, and the port is returned. This method should only be used
6404 for obtaining an unused port in order to pass to an external program
6405 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6406 a parameter to a server-oriented class that doesn't give you direct
6407 access to the underlying socket used.
6408
6409 Finally, test_support.HOST has been introduced, which should be used
6410 for the host argument of any relevant socket calls (i.e. bind and
6411 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006412
6413 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006415 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6416 test_asynchat and test_socket_ssl.
6417
Georg Brandl3ee81df2008-05-17 18:14:43 +00006418 It is now possible for multiple instances of the regression test
6419 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006698- Added the future_builtins module, which contains hex() and oct().
6699 These are the PEP 3127 version of these functions, designed to be
6700 compatible with the hex() and oct() builtins from Python 3.0. They
6701 differ slightly in their output formats from the existing, unchanged
6702 Python 2.6 builtins. The expected usage of the future_builtins
6703 module is:
6704 from future_builtins import hex, oct
6705
Eric Smith7ef40bf2008-02-20 23:34:22 +00006706- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6707 exponents for exponents with absolute value < 100. Follows C99
6708 standard. This is a change on Windows, which would use 3 digits.
6709 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6710 so that any alterations it does to the resulting string will be
6711 available in stringlib/formatter.h (for float.__format__).
6712
Eric Smith5a3c1352008-02-19 13:21:56 +00006713- Implemented PEP 3101, Advanced String Formatting. This adds a new
6714 builtin format(); a format() method for str and unicode; a
6715 __format__() method to object, str, unicode, int, long, float, and
6716 datetime; the class string.Formatter; and the C API
6717 PyObject_Format().
6718
Georg Brandl3ee81df2008-05-17 18:14:43 +00006719- Fixed several potential crashes, all caused by specially crafted
6720 __del__ methods exploiting objects in temporarily inconsistent
6721 state.

6732 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006733
Georg Brandl3ee81df2008-05-17 18:14:43 +00006734- Issue #2045: Fix an infinite recursion triggered when printing a
6735 subclass of collections.defaultdict, if its default_factory is set
6736 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006737
Christian Heimesf75dbef2008-02-08 00:11:31 +00006738- Fixed a minor memory leak in dictobject.c. The content of the free

6747
Georg Brandl3ee81df2008-05-17 18:14:43 +00006748- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

6750 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006761- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6762 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006763
Georg Brandl3ee81df2008-05-17 18:14:43 +00006764- Patch #1473257: generator objects gain a gi_code attribute. This is
6765 the same object as the func_code attribute of the function that
6766 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Issue #1920: "while 0" statements were completely removed by the
6769 compiler, even in the presence of an "else" clause, which is
6770 supposed to be run when the condition is false. Now the compiler
6771 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006772
Guido van Rossumeead05f2008-01-24 18:21:02 +00006773- A few crashers fixed: weakref_in_del.py (issue #1377858);
6774 loosing_dict_ref.py (issue #1303614, test67.py);
6775 borrowed_ref_[34].py (not in tracker).
6776
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006777- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006778 suppressed while an extension is loaded by calling SetErrorMode in
6779 dynload_win.c. The error is still reported properly.
6780
Georg Brandl3ee81df2008-05-17 18:14:43 +00006781- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006782 several extension methods and modules do not work without unicode
6783 support.
6784
Georg Brandl26543b12008-01-21 18:36:51 +00006785- Issue #1882: when compiling code from a string, encoding cookies in the
6786 second line of code were not always recognized correctly.
6787
Georg Brandl14404b62008-01-19 19:27:05 +00006788- Issue #1679: "0x" was taken as a valid integer literal.
6789
Georg Brandl6caad7d2008-01-26 14:19:22 +00006790- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006791 added.
6792
Christian Heimesc94e2b52008-01-14 04:13:37 +00006793- sys.float_info / PyFloat_GetInfo: The floating point information
6794 object was converted from a dict to a specialized structseq object.
6795
Georg Brandl3ee81df2008-05-17 18:14:43 +00006796- Patch #1816: Added sys.flags structseq. It exposes the status of
6797 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006798
Georg Brandl3ee81df2008-05-17 18:14:43 +00006799- Objects/structseq.c: Implemented new structseq representation. The
6800 patch makes structseqs (e.g. the return value of os.stat) more
6801 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- Patch #1700288: added a type attribute cache that caches method
6804 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006805
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006806- Bug #1776: __import__() no longer accepts filenames on any platform.
6807 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006808
Georg Brandlaed6c662008-01-07 17:25:53 +00006809- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6812 envvar and sys.dont_write_bytecode attribute. All these can be set
6813 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006814
Georg Brandl3ee81df2008-05-17 18:14:43 +00006815- Improve some exception messages when Windows fails to load an
6816 extension module. Now we get for example '%1 is not a valid Win32
6817 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006818
Georg Brandl3ee81df2008-05-17 18:14:43 +00006819- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006821- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6822 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006823
Christian Heimes0a8143f2007-12-18 23:22:54 +00006824- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825 and INF. float("nan"), float("inf") and float("-inf") now work on
6826 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006827
Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- Compiler now generates simpler and faster code for dictionary
6829 literals. The oparg for BUILD_MAP now indicates an estimated
6830 dictionary size. There is a new opcode, STORE_MAP, for adding
6831 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006832
Georg Brandl3ee81df2008-05-17 18:14:43 +00006833- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006834
Georg Brandl3ee81df2008-05-17 18:14:43 +00006835- Issue #1620: New property decorator syntax was modifying the
6836 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006837
Georg Brandl3ee81df2008-05-17 18:14:43 +00006838- Issue #1538: Avoid copying string in split/rsplit if the split char
6839 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006840
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006841- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006842 SystemError.
6843
Nick Coghlanef01d822007-12-03 12:55:17 +00006844- PEP 366: Allow explicit relative imports when executing modules
6845 inside packages with the -m switch via a new module level
6846 __package__ attribute.
6847
Georg Brandl3ee81df2008-05-17 18:14:43 +00006848- Issue #1402: Fix a crash on exit, when another thread is still
6849 running, and if the deallocation of its frames somehow calls the
6850 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006851

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006855 attribute of an empty cell object.
6856
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Issue #1460: The utf-7 incremental decoder did not accept truncated
6858 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006859
Georg Brandl3ee81df2008-05-17 18:14:43 +00006860- Patch #1739468: Directories and zipfiles containing a __main__.py
6861 file can now be directly executed by passing their name to the
6862 interpreter. The directory/zipfile is automatically inserted as the
6863 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006864
Georg Brandl3ee81df2008-05-17 18:14:43 +00006865- Issue #1265: Fix a problem with sys.settrace, if the tracing
6866 function uses a generator expression when at the same time the
6867 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006868
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006869- sets and frozensets now have an isdisjoint() method.
6870
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006871- optimize the performance of builtin.sum().
6872
Neal Norwitz44f326e2007-10-05 05:29:17 +00006873- Fix warnings found by the new version of the Coverity checker.
6874
Georg Brandl21e99f42010-03-07 15:23:59 +00006875- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006876 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6877 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006878
Georg Brandl3ee81df2008-05-17 18:14:43 +00006879- Issue #1686386: Tuple's tp_repr did not take into account the
6880 possibility of having a self-referential tuple, which is possible
6881 from C code. Nor did object's tp_str consider that a type's tp_str
6882 could do something that could lead to an inifinite recursion.
6883 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6884 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Issue #1164: It was possible to trigger deadlock when using the
6887 'print' statement to write to a file since the GIL was not released
6888 as needed. Now PyObject_Print() does the right thing along with
6889 various tp_print implementations of the built-in types and those in
6890 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006891
Georg Brandl3ee81df2008-05-17 18:14:43 +00006892- Issue #1147: Exceptions were directly allowing string exceptions in
6893 their throw() method even though string exceptions no longer
6894 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- Issue #1096: Prevent a segfault from getting the repr of a very
6897 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006898
Brett Cannon1e534b52007-09-07 04:18:30 +00006899- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006900 PyObject_Call() never calling back out to Python code to trigger
6901 recursion depth updates/checks. Required the creation of a static
6902 RuntimeError instance in case normalizing an exception put the
6903 recursion check value past its limit. Fixes crashers
6904 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006905
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906- Patch #1031213: Decode source line in SyntaxErrors back to its
6907 original source encoding.

6910 with %G.
6911
Georg Brandl3ee81df2008-05-17 18:14:43 +00006912- Prevent expandtabs() on string and unicode objects from causing a
6913 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006914

Georg Brandla5ea6892007-06-01 11:33:33 +00006918
Neal Norwitz0ac60192007-05-27 04:08:54 +00006919- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920 __*__ attributes. (Some already existed, e.g., __doc__ and
6921 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006922
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006923- Add -3 option to the interpreter to warn about features that are
6924 deprecated and will be changed/removed in Python 3.0.
6925
Georg Brandl2134e752007-05-21 20:34:16 +00006926- Patch #1686487: you can now pass any mapping after '**' in function
6927 calls.
6928
Collin Winter62903052007-05-18 23:11:24 +00006929- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930 "except E as target:". This is to provide forwards compatibility
6931 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006932
Brett Cannon229cee22007-05-05 01:34:02 +00006933- Deprecate BaseException.message as per PEP 352.
6934
Georg Brandl3ee81df2008-05-17 18:14:43 +00006935- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006936 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006937
Vinay Sajip8549ce32007-05-06 17:53:37 +00006938- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006939 setting a plain string, ie don't expand to single letter identifiers.
6940
Raymond Hettinger13936692007-04-11 18:40:58 +00006941- Request #1191699: Slices can now be pickled.
6942
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006943- Request #1193128: str.translate() now allows a None argument for
6944 translations that only remove characters without re-mapping the
6945 remaining characters.
6946
Georg Brandl5cb76c12007-03-21 09:00:39 +00006947- Patch #1682205: a TypeError while unpacking an iterable is no longer
6948 masked by a generic one with the message "unpack non-sequence".
6949
Neal Norwitzaa754b72007-03-21 06:39:48 +00006950- Remove unused file Python/fmod.c.
6951
Guido van Rossum143b5642007-03-23 04:58:42 +00006952- Bug #1683368: The object.__init__() and object.__new__() methods are
6953 now stricter in rejecting excess arguments. The only time when
6954 either allows excess arguments is when it is not overridden and the
6955 other one is. For backwards compatibility, when both are
6956 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006957 warning later). Also, type.__init__() insists on the same signature
6958 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6961 object to complex using its __complex__() method before falling back
6962 to the __float__() method. Therefore, the functions in the cmath
6963 module now can operate on objects that define a __complex__()
6964 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006965
Georg Brandl3ee81df2008-05-17 18:14:43 +00006966- Patch #1623563: allow __class__ assignment for classes with
6967 __slots__. The old and the new class are still required to have the
6968 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006969
Georg Brandl3ee81df2008-05-17 18:14:43 +00006970- Patch #1642547: Fix an error/crash when encountering syntax errors
6971 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006973- Patch #1462488: Python no longer segfaults when
6974 ``object.__reduce_ex__()`` is called with an object that is faking
6975 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006976
Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Patch #1680015: Don't modify __slots__ tuple if it contains an
6978 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00006980- Patch #1444529: the builtin compile() now accepts keyword arguments.
6981
Georg Brandl7b9c5552007-03-12 14:30:05 +00006982- Bug #1678647: write a newline after printing an exception in any
6983 case, even when converting the value to a string failed.
6984
Georg Brandl871f1bc2007-03-12 13:17:36 +00006985- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006986 its argument, if it exists. If not, it will work like before. This
6987 allows customizing the output of dir() in the presence of a
6988 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006989
Collin Winter276887b2007-03-12 16:11:39 +00006990- Patch #922167: Python no longer segfaults when faced with infinitely
6991 self-recursive reload() calls (as reported by bug #742342).
6992
Georg Brandl3ee81df2008-05-17 18:14:43 +00006993- Patch #1675981: remove unreachable code from ``type.__new__()``
6994 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006995
Georg Brandl3ee81df2008-05-17 18:14:43 +00006996- Patch #1491866: change the complex() constructor to allow
6997 parthensized forms. This means complex(repr(x)) now works instead of
6998 raising a ValueError.

7510
Facundo Batistad918a652007-04-24 13:54:38 +00007511- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007512 the client's request was successfully received, understood, and
7513 accepted. Now in these cases no error is raised in urllib (issue
7514 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007515

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007522- Added a timeout parameter to the constructor of other protocols
7523 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7524 work started with create_connection() and timeout in httplib, and
7525 closes patch #723312.
7526
Vinay Sajip8549ce32007-05-06 17:53:37 +00007527- Patch #1676823: Added create_connection() to socket.py, which may be
7528 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007529 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007530
Martin v. Löwis0af33882007-03-23 13:27:15 +00007531- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7551
Georg Brandlf66b6032007-03-14 08:27:52 +00007552- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007553 AttributeError instead of an IOError when the server's response
7554 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007555
Georg Brandl3ee81df2008-05-17 18:14:43 +00007556- Patch #957650: "%var%" environment variable references are now
7557 properly expanded in ntpath.expandvars(), also "~user" home
7558 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00007559
Georg Brandl3ee81df2008-05-17 18:14:43 +00007560- Patch #1429539: pdb now correctly initializes the __main__ module
7561 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007562 correctly now.
7563
Georg Brandlbad6f192007-03-13 21:32:56 +00007564- The nonobvious commands.getstatus() function is now deprecated.

7570
Georg Brandl3ee81df2008-05-17 18:14:43 +00007571- Patch #1530482: add pydoc.render_doc() which returns the
7572 documentation for a thing instead of paging it to stdout, which
7573 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007574
Georg Brandl3ee81df2008-05-17 18:14:43 +00007575- Patch #1533909: the timeit module now accepts callables in addition

7581 parameter which can be set to False to prevent the default
7582 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00007584- Patch #1581073: add a flag to textwrap that prevents the dropping of
7585 whitespace while wrapping.
7586
Georg Brandl92a6bae2007-03-13 17:43:32 +00007587- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007588 are set for invalid interpolation sequences that would lead to
7589 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007590

7603
Georg Brandl94fe3f52007-03-13 09:32:11 +00007604- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007605 field names in its exception message if you try to write a record
7606 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007624

7632 returned string up to the first NUL character.
7633

7643
Georg Brandl3ee81df2008-05-17 18:14:43 +00007644- unittest now verifies more of its assumptions. In particular,
7645 TestCase and TestSuite subclasses (not instances) are no longer
7646 accepted in TestSuite.addTest(). This should cause no
7647 incompatibility since it never made sense with ordinary subclasses
7648 -- the failure just occurred later, with a more cumbersome
7649 exception.

7658 given a unicode argument and os.listdir() returns unicode filenames.
7659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00008038 time so that opening a database previously created with the DB_DUP
8039 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8040 opens. Specifically: dictionary assignment to a DB object will
8041 replace all values for a given key when the database allows
8042 duplicate values. DB users should use DB.put(k, v) when they want
8043 to store duplicates; not DB[k] = v.

8050 characters with ASCII value less than 32. Also, it correctly quotes
8051 dots only if they occur on a single line, as opposed to the previous
8052 behavior of quoting dots if they are the second character of any
8053 line.
