Florent Xiclunac2279652012-02-12 14:49:03 +0100612- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100613 has left two versions of customize_compiler, the original in
614 distutils.sysconfig and another copy in distutils.ccompiler, with some
615 parts of distutils calling one and others using the other.
616 Complete the revert back to only having one in distutils.sysconfig as
617 is the case in 3.x.
618
Ned Deily0d0ea482012-02-10 12:59:06 +0100619- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
620 Distutils-based packages with C extension modules may fail because
621 Apple has removed gcc-4.2, the version used to build python.org
622 64-bit/32-bit Pythons. If the user does not explicitly override
623 the default C compiler by setting the CC environment variable,
624 Distutils will now attempt to compile extension modules with clang
625 if gcc-4.2 is required but not found. Also as a convenience, if
626 the user does explicitly set CC, substitute its value as the default
627 compiler in the Distutils LDSHARED configuration variable for OS X.
628 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
629 SDK, neither of which are available in Xcode 4. This change does not
630 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700903- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
904 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
905 interpreter process. This could cause failures in non-Distutils subprocesses
906 and was unreliable since tests or user programs could modify the interpreter
907 environment after Distutils set it. Instead, have Distutils set the the
908 deployment target only in the environment of each build subprocess. It is
909 still possible to globally override the default by setting
910 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
911 greater or equal to the default value, the value with which the interpreter
912 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400940- sys.setcheckinterval() now updates the current ticker count as well as
941 updating the check interval, so if the user decreases the check interval,
942 the ticker doesn't have to wind down to zero from the old starting point
943 before the new interval takes effect. And if the user increases the
944 interval, it makes sure the new limit takes effect right away rather have an
945 early task switch before recognizing the new interval.

2359
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002360- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2361 start byte and the continuation byte(s) are now considered invalid, instead
2362 of the number of bytes specified by the start byte.
2363 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2364 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2365 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2366 Previous versions returned a single u'\ufffd'.
2367
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002368- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002369 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2370 arises from the "Overriding __eq__ blocks inheritance ..." warning
2371 when turned into an exception: in this case the exception simply
2372 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002373
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002374- Issue #8748: Fix two issues with comparisons between complex and integer
2375 objects. (1) The comparison could incorrectly return True in some cases
2376 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2377 (2) The comparison raised an OverflowError for large integers, leading
2378 to unpredictable exceptions when combining integers and complex objects
2379 in sets or dicts.
2380
Mark Dickinson81336372010-05-30 12:12:25 +00002381- Issue #5211: Implicit coercion for the complex type is now completely
2382 removed. (Coercion for arithmetic operations was already removed in 2.7
2383 alpha 4, but coercion for rich comparisons was accidentally left in.)
2384
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002385- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2386 and error handler, instead of writing to the C stderr file in utf-8
2387
Georg Brandlfee0f442010-05-22 21:26:21 +00002388- Issue #7902: When using explicit relative import syntax, don't try implicit

2520 using its __int__ method. Previously, only small arguments were treated this

2749 changed.
2750
Georg Brandlfee0f442010-05-22 21:26:21 +00002751- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002752 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00002761- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2762 with a non-empty format string. This is an effort to future-proof user
2763 code. If a derived class does not currently implement __format__ but later
2764 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002765 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002766 Python 3.3 and it will be an error in Python 3.4.

2817 InvalidOperation instead of returning False. (Comparisons involving a quiet
2818 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

2950 the set of integer codes for which it was used differed between native packing
2951 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003137- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00003138 thread could raise an incorrect RuntimeError about not holding the import
3139 lock. The import lock is now reinitialized after fork.

Georg Brandlba83f822010-03-14 09:50:54 +00003160- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00003161 is run with the -OO flag. Tests requiring docstrings are skipped.
3162
Georg Brandlba83f822010-03-14 09:50:54 +00003163- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3164 now also used by regrtest to run all the tests in a temporary directory. The
3165 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3166 Xicluna who helped with the patch.

3183 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003184 library would return a bogus result; on Solaris, it was possible to crash the
3185 interpreter. Patch by Stefan Krah.

3196 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00003197
Georg Brandlba83f822010-03-14 09:50:54 +00003198- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3199 and add the additional members returned in an OSVERSIONINFOEX structure. The
3200 new members are service_pack_major, service_pack_minor, suite_mask, and
3201 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00003202
Georg Brandlba83f822010-03-14 09:50:54 +00003203- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3204 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3205 returning NULL. The macro now returns a statically allocated empty string
3206 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00003207
Antoine Pitrou64672132010-01-13 07:55:48 +00003208- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00003215 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
3216 strings,
3217 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3218 numeric strings corresponding to subnormal values,
3219 (3) a memory leak for some values large enough to cause overflow, and
3220 (4) a number of flaws that could lead to incorrectly rounded results.
3221

3223 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00003224

3236
R. David Murray63e4fd72010-02-10 22:42:04 +00003237- Issue #7835: shelve should no longer produce mysterious warnings during
3238 interpreter shutdown.
3239
Georg Brandlba83f822010-03-14 09:50:54 +00003240- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
3241 XML processing instructions and comments. These raw characters are allowed
3242 by the XML specification, and are necessary when outputting e.g. PHP code in
3243 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +00003250
Antoine Pitroud840e512010-02-04 20:20:18 +00003251- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003252 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003253 Also, raise ValueError rather than TypeError when an unknown TIPC address
3254 type is specified. Patch by Brian Curtin.
3255
Vinay Sajip28c382f2010-02-04 18:48:53 +00003256- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003258- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003259 file position when calling `truncate()`. It would previously change the file
3260 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003261 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3262
Georg Brandlba83f822010-03-14 09:50:54 +00003263- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3264 class used to represent files stored inside an archive. The new
3265 implementation is significantly faster and can be wrapped in a
3266 ``io.BufferedReader`` object for more speedups. It also solves an issue
3267 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3268 Patch by Nir Aides.

3276 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00003277
Georg Brandlba83f822010-03-14 09:50:54 +00003278- Issue #7748: Since unicode values are supported for some metadata options in
3279 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3280 encoded string for them. This ensures that the upload and register commands
3281 send the correct values to PyPI without any error.

3357
Georg Brandlba83f822010-03-14 09:50:54 +00003358- The ``__complex__()`` method is now looked up on the class of instances to
3359 make it consistent with other special methods.

3363
Mark Dickinson1b34d252010-01-01 17:27:30 +00003364- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003365 DeprecationWarning when passed a float argument where an integer was expected.
3366 These functions and methods now raise TypeError instead. The majority of the
3367 effects of this change are in the extension modules, but some core functions
3368 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3369 and many unicode/str methods.

3383 of integers: the result of a/b is now correctly rounded for ints a and b (at
3384 least on IEEE 754 platforms), and in particular does not depend on the
3385 internal representation of a long.

3393
Georg Brandlba83f822010-03-14 09:50:54 +00003394 These executables now work properly with the arch(1) command: ``arch -ppc
3395 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003552- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3553 decimal string that's guaranteed to round back to x under correct rounding
3554 (with round-half-to-even rounding mode). Previously it gave a string based on
3555 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3556 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3557 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003559- Issue #7117: On almost all platforms: float-to-string and string-to-float
3560 conversions within Python are now correctly rounded. Places these conversions
3561 occur include: str for floats and complex numbers; the float and complex
3562 constructors; old-style and new-style numeric formatting; serialization and
3563 deserialization of floats and complex numbers using marshal, pickle and json;
3564 parsing of float and imaginary literals in Python code; Decimal-to-float
3565 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003566
Georg Brandlba83f822010-03-14 09:50:54 +00003567 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3568 providing correctly-rounded strtod and dtoa C functions. This code is
3569 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3570 the C compiler. There may be a small number of platforms on which correct
3571 operation of this code cannot be guaranteed, so the code is not used: notably,
3572 this applies to platforms where the C double format is not IEEE 754 binary64,
3573 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3574 and Python's configure script is unable to determine how to change the FPU
3575 precision. On these platforms conversions use the platform strtod and dtoa,
3576 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003578- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3579 uses the correctly-rounded string <-> float conversions described above (when
3580 available), and so produces correctly rounded results that will display nicely
3581 under the float repr. There are two related small changes: (1) round now
3582 accepts any class with an ``__index__()`` method for its second argument (but
3583 no longer accepts floats for the second argument), and (2) an excessively
3584 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3585 raises an exception.

3812 internal representation of integers, for performance reasons. Base 2**30 is
3813 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00003998- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4000 gives improved memory leak detection when running under Valgrind, while taking
4001 advantage of pymalloc at other times.

5168 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5169 neither __int__ nor __long__, TypeError used to be raised (with a
5170 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5171 struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005368- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5370 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5371 ``printf`` function, whereas PyString_FromFormat has an independent
5372 implementation and uses "%zd" on all platforms for size_t values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005390 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005391 was correctly parsed but parsing of subsequent arguments failed.
5392
Vinay Sajip35e3b032008-09-01 14:33:59 +00005393- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005394 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5395 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5396 when given a tuple of classes as second argument, were looking up
5397 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5398 type object.
5399

5409 function 'stringlib_contains_obj'.
5410
Benjamin Peterson712ee922008-08-24 18:10:20 +00005411- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00005469 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5470 for catch_warnings() also led to an improvement in the raising of a
5471 DeprecationWarning related to warnings.warn_explicit().
5472

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005537What's New in Python 2.6 beta 3?
5538================================
5539
Barry Warsaw07a4a382008-08-21 01:15:08 +00005540*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005541
5542Core and Builtins
5543-----------------
5544
Guido van Rossumf8402962008-08-20 15:01:50 +00005545- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5546 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5547 extensions do not automatically benefit from the class attribute
5548 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5549 to their tp_flags field if they care. This is a backwards
5550 compatibility feature; in 3.0, all types will use the cache by
5551 default.
5552
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005553- Keyword arguments can now follow starred arguments. (``f(a, *args,
5554 keyword=23)`` is now valid syntax.)
5555
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005556- ctypes function pointers that are COM methods have a boolean True
5557 value again.
5558
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005559- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5560 by denying s# to parse objects that have a releasebuffer procedure,
5561 and introducing s*.
5562
Georg Brandl1e13ea92008-08-11 09:07:59 +00005563- Issue #3537: Fix an assertion failure when an empty but presized dict
5564 object was stored in the freelist.
5565
Mark Dickinsonb6467572008-08-04 21:30:09 +00005566- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5567 ValueError consistently across platforms.
5568
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005569- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5570 (64bit Unix, for example), unichr() would truncate its argument and return
5571 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5572
Neal Norwitze7d8be82008-07-31 17:17:14 +00005573- Apply security patches from Apple.
5574
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005575- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5576 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5577
Antoine Pitrou92f82162008-07-25 22:22:08 +00005578- Issue #1819: function calls with several named parameters are now on
5579 average 35% faster (as measured by pybench).
5580
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005581- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5582 the python debugger steps into a class statement: the free variables (local
5583 variables defined in an outer scope) would be deleted from the outer scope.
5584
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005585- Issue #2620: Overflow checking when allocating or reallocating memory
5586 was not always being done properly in some python types and extension
5587 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5588 all been updated to perform better checks and places in the code that
5589 would previously leak memory on the error path when such an allocation
5590 failed have been fixed.

5593-------
5594
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005595- Issue #3612: Added some missing basic types in ctypes.wintypes.
5596
Benjamin Petersone977ad42008-08-20 01:42:01 +00005597- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5598 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5599
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005600- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5601 version reported by these tools does not necessarily follow the python
5602 version numbering scheme, so the module is less strict when parsing it.
5603
Nick Coghlanf70385a2008-08-18 12:42:46 +00005604- Issue #2235: Added Py3k warnings for types which will become unhashable
5605 under the stricter __hash__ inheritance rules in 3.0. Several types
5606 which did not meet the rules for hash invariants and were already
5607 unhashable in 3.0 have now been explicitly flagged as unhashable in
5608 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5609 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5610
Brett Cannon88f801d2008-08-18 00:46:22 +00005611- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5612 imported into the module but exposed as part of the module's API.
5613
Brett Cannon7b96f072008-08-18 00:41:11 +00005614- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5615
Brett Cannon46225e72008-08-18 00:36:52 +00005616- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005618- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5619
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005620- Issue #3575: Incremental decoder's decode function now takes bytearray
5621 by using 's*' instead of 't#'.
5622
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005623- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005624 fails unicode conversion on 2nd parameter. (windows only)
5625
Georg Brandl222e2082010-08-01 22:27:39 +00005626- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005627 in a redirect.
5628
Brett Cannonabe423e2008-08-16 21:47:07 +00005629- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005630 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005631
Facundo Batistaeb90b782008-08-16 14:44:07 +00005632- Issue #2776: fixed small issue when handling an URL with double slash
5633 after a 302 response in the case of not going through a proxy.
5634
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005635- Issue #2676: in the email package, content-type parsing was hanging on
5636 pathological input because of quadratic or exponential behaviour of a
5637 regular expression.
5638
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005639- Issue #3476: binary buffered reading through the new "io" library is now
5640 thread-safe.
5641
Brett Cannonbf3157b2008-08-14 05:00:03 +00005642- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5643 since mimetools itself is deprecated. Because modules are cached, all
5644 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5645
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005646- Issue #3134: shutil referenced undefined WindowsError symbol.
5647
Robert Schuppenies14646332008-08-10 11:01:53 +00005648- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5649 menu entries were not deleted.
5650
Brett Cannon83e81842008-08-09 23:30:55 +00005651- Copied the implementation of reduce() to _functools.reduce() to have a
5652 version that did not raise a DeprecationWarning under -3.
5653
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005654- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5655 a MemoryError rather than silently stop the iteration.
5656
Guido van Rossum59ce9012008-08-09 14:55:34 +00005657- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5658 to _sre.compile() will now be rejected. This should not affect anybody
5659 since the re.compile() function never generates invalid re-bytecode.
5660
Skip Montanaroa032bf42008-08-08 22:52:51 +00005661- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5662 upon first access it can be automatically initialized from the csv file if
5663 it wasn't initialized during instantiation.
5664
Brett Cannon3aa2a492008-08-06 22:28:09 +00005665- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5666 the reload() built-in has been removed.
5667
Brett Cannon7e30b672008-08-04 21:52:25 +00005668- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005669 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005670 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

5737-----------------
5738
Georg Brandl3e483f62008-07-16 22:57:41 +00005739- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5740 its methods now allow for items objects that can be converted to
5741 an integer using operator.index().
5742
Mark Dickinson64b7e502008-07-16 09:40:03 +00005743- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5744 produced a ValueError instead of giving the correct float.
5745
Eric Smitha5fa5a22008-07-16 00:11:49 +00005746- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5747 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5748
Mark Dickinson7103aa42008-07-15 19:08:33 +00005749- Issue #3008: the float type has a new instance method 'float.hex'
5750 and a new class method 'float.fromhex' to convert floating-point
5751 numbers to and from hexadecimal strings, respectively.
5752
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005753- Issue #2235: __hash__ is once again inherited by default. To allow
5754 collections.Hashable to remain meaningful in the presence of the
5755 default hash implementation (object.__hash__), it is now possible
5756 to explicit block inheritance of hash by setting __hash__=None at
5757 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5758 level.
5759
Nick Coghlanb028f502008-07-13 14:52:36 +00005760- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5761 the parent module cannot be found while performing an absolute import.
5762 This means that an incorrectly defined __package__ attribute will
5763 now only prevent relative imports in that module rather than causing
5764 all imports from that module to fail.
5765
Nick Coghlan14ff9942008-07-08 14:21:42 +00005766- Issue #2517: Allow unicode messages in Exceptions again by correctly

5776 another thread's dictionary.
5777
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005778- Issue #3004: Minor change to slice.indices(): the start and stop
5779 arguments are now treated identically, making the behaviour easier
5780 to describe and understand. For example, slice(None, -10,
5781 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5782 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5783 10, -1).
5784
Georg Brandl278fc502008-07-19 12:46:12 +00005785- Issue #3219: Calling a function with repeated keyword arguments,
5786 f(a=2, a=23), would not cause a syntax error. This was a regression
5787 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005825- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5826 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005827 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005828 content-length. The problem had been corrected in the 2.4 branch, but never
5829 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005844- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6239 This is controlled by the configure argument ``--with-universal-archs``:
6240
6241 - ``--with-universal-archs=all``: install 4-way universal
6242
6243 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6244
6245 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6246
6247 This option should be used in combination with ``--enable-universalsdk=``.
6248
6249 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6257- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006258
6259- The PyString functions have been renamed to PyBytes. A batch of
6260 defines were added so that the linker still sees the original
6261 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Issue #1631171: Re-implement the 'warnings' module in C (the
6300 original Python code has been kept as backup). This will allow for
6301 using the 'warning's machinery in such places as the parser where
6302 use of pure Python code is not possible. Both the ``showarning()``
6303 and ``formatwarning()`` gain an optional 'line' argument which is
6304 not called by default for backwards-compatibility reasons. Setting
6305 ``warnings.showwarning()`` to an implementation that lacks support
6306 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006348- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006349 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006369- Issue #2550: The approach used by client/server code for obtaining
6370 ports to listen on in network-oriented tests has been refined in an
6371 effort to facilitate running multiple instances of the entire
6372 regression test suite in parallel without issue.
6373 test_support.bind_port() has been fixed such that it will always
6374 return a unique port -- which wasn't always the case with the
6375 previous implementation, especially if socket options had been set
6376 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6377 new implementation of bind_port() will actually raise an exception
6378 if it is passed an AF_INET/SOCK_STREAM socket with either the
6379 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6380 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6381 the socket it's been passed. This currently only applies to
6382 Windows. This option prevents any other sockets from binding to the
6383 host/port we've bound to, thus removing the possibility of the
6384 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6385 when a second SOCK_STREAM socket binds and accepts to a host/port
6386 that's already been bound by another socket. The optional preferred
6387 port parameter to bind_port() has been removed. Under no
6388 circumstances should tests be hard coding ports!
6389
6390 test_support.find_unused_port() has also been introduced, which will
6391 pass a temporary socket object to bind_port() in order to obtain an
6392 unused port. The temporary socket object is then closed and
6393 deleted, and the port is returned. This method should only be used
6394 for obtaining an unused port in order to pass to an external program
6395 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6396 a parameter to a server-oriented class that doesn't give you direct
6397 access to the underlying socket used.
6398
6399 Finally, test_support.HOST has been introduced, which should be used
6400 for the host argument of any relevant socket calls (i.e. bind and
6401 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006402
6403 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006404 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006405 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6406 test_asynchat and test_socket_ssl.
6407
Georg Brandl3ee81df2008-05-17 18:14:43 +00006408 It is now possible for multiple instances of the regression test
6409 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006688- Added the future_builtins module, which contains hex() and oct().
6689 These are the PEP 3127 version of these functions, designed to be
6690 compatible with the hex() and oct() builtins from Python 3.0. They
6691 differ slightly in their output formats from the existing, unchanged
6692 Python 2.6 builtins. The expected usage of the future_builtins
6693 module is:
6694 from future_builtins import hex, oct
6695
Eric Smith7ef40bf2008-02-20 23:34:22 +00006696- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6697 exponents for exponents with absolute value < 100. Follows C99
6698 standard. This is a change on Windows, which would use 3 digits.
6699 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6700 so that any alterations it does to the resulting string will be
6701 available in stringlib/formatter.h (for float.__format__).
6702
Eric Smith5a3c1352008-02-19 13:21:56 +00006703- Implemented PEP 3101, Advanced String Formatting. This adds a new
6704 builtin format(); a format() method for str and unicode; a
6705 __format__() method to object, str, unicode, int, long, float, and
6706 datetime; the class string.Formatter; and the C API
6707 PyObject_Format().
6708
Georg Brandl3ee81df2008-05-17 18:14:43 +00006709- Fixed several potential crashes, all caused by specially crafted
6710 __del__ methods exploiting objects in temporarily inconsistent
6711 state.

6722 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006723
Georg Brandl3ee81df2008-05-17 18:14:43 +00006724- Issue #2045: Fix an infinite recursion triggered when printing a
6725 subclass of collections.defaultdict, if its default_factory is set
6726 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006727
Christian Heimesf75dbef2008-02-08 00:11:31 +00006728- Fixed a minor memory leak in dictobject.c. The content of the free

6737
Georg Brandl3ee81df2008-05-17 18:14:43 +00006738- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6739 calls. Python expected the return type int but the fork familie
6740 returns pi_t.

6755 the same object as the func_code attribute of the function that
6756 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006757
Georg Brandl3ee81df2008-05-17 18:14:43 +00006758- Issue #1920: "while 0" statements were completely removed by the
6759 compiler, even in the presence of an "else" clause, which is
6760 supposed to be run when the condition is false. Now the compiler
6761 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006762
Guido van Rossumeead05f2008-01-24 18:21:02 +00006763- A few crashers fixed: weakref_in_del.py (issue #1377858);
6764 loosing_dict_ref.py (issue #1303614, test67.py);
6765 borrowed_ref_[34].py (not in tracker).
6766
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006767- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006768 suppressed while an extension is loaded by calling SetErrorMode in
6769 dynload_win.c. The error is still reported properly.
6770
Georg Brandl3ee81df2008-05-17 18:14:43 +00006771- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006772 several extension methods and modules do not work without unicode
6773 support.
6774
Georg Brandl26543b12008-01-21 18:36:51 +00006775- Issue #1882: when compiling code from a string, encoding cookies in the
6776 second line of code were not always recognized correctly.
6777
Georg Brandl14404b62008-01-19 19:27:05 +00006778- Issue #1679: "0x" was taken as a valid integer literal.
6779
Georg Brandl6caad7d2008-01-26 14:19:22 +00006780- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006781 added.
6782
Christian Heimesc94e2b52008-01-14 04:13:37 +00006783- sys.float_info / PyFloat_GetInfo: The floating point information
6784 object was converted from a dict to a specialized structseq object.
6785
Georg Brandl3ee81df2008-05-17 18:14:43 +00006786- Patch #1816: Added sys.flags structseq. It exposes the status of
6787 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006788
Georg Brandl3ee81df2008-05-17 18:14:43 +00006789- Objects/structseq.c: Implemented new structseq representation. The
6790 patch makes structseqs (e.g. the return value of os.stat) more
6791 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006792
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Patch #1700288: added a type attribute cache that caches method
6794 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006795
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006796- Bug #1776: __import__() no longer accepts filenames on any platform.
6797 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006798
Georg Brandlaed6c662008-01-07 17:25:53 +00006799- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6800
Georg Brandl3ee81df2008-05-17 18:14:43 +00006801- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6802 envvar and sys.dont_write_bytecode attribute. All these can be set
6803 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006804
Georg Brandl3ee81df2008-05-17 18:14:43 +00006805- Improve some exception messages when Windows fails to load an
6806 extension module. Now we get for example '%1 is not a valid Win32
6807 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006808
Georg Brandl3ee81df2008-05-17 18:14:43 +00006809- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00006810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6812 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006813
Christian Heimes0a8143f2007-12-18 23:22:54 +00006814- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006815 and INF. float("nan"), float("inf") and float("-inf") now work on
6816 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006817
Georg Brandl3ee81df2008-05-17 18:14:43 +00006818- Compiler now generates simpler and faster code for dictionary
6819 literals. The oparg for BUILD_MAP now indicates an estimated
6820 dictionary size. There is a new opcode, STORE_MAP, for adding
6821 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006822
Georg Brandl3ee81df2008-05-17 18:14:43 +00006823- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Issue #1620: New property decorator syntax was modifying the
6826 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006827
Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- Issue #1538: Avoid copying string in split/rsplit if the split char
6829 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006830
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006831- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006832 SystemError.
6833
Nick Coghlanef01d822007-12-03 12:55:17 +00006834- PEP 366: Allow explicit relative imports when executing modules
6835 inside packages with the -m switch via a new module level
6836 __package__ attribute.
6837
Georg Brandl3ee81df2008-05-17 18:14:43 +00006838- Issue #1402: Fix a crash on exit, when another thread is still
6839 running, and if the deallocation of its frames somehow calls the
6840 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006841
Christian Heimes28104c52007-11-27 23:16:44 +00006842- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
6843
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00006844- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006845 attribute of an empty cell object.
6846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- Issue #1460: The utf-7 incremental decoder did not accept truncated
6848 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006849
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850- Patch #1739468: Directories and zipfiles containing a __main__.py
6851 file can now be directly executed by passing their name to the
6852 interpreter. The directory/zipfile is automatically inserted as the
6853 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006854
Georg Brandl3ee81df2008-05-17 18:14:43 +00006855- Issue #1265: Fix a problem with sys.settrace, if the tracing
6856 function uses a generator expression when at the same time the
6857 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006858
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006859- sets and frozensets now have an isdisjoint() method.
6860
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006861- optimize the performance of builtin.sum().
6862
Neal Norwitz44f326e2007-10-05 05:29:17 +00006863- Fix warnings found by the new version of the Coverity checker.
6864
Georg Brandl21e99f42010-03-07 15:23:59 +00006865- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6867 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006868
Georg Brandl3ee81df2008-05-17 18:14:43 +00006869- Issue #1686386: Tuple's tp_repr did not take into account the
6870 possibility of having a self-referential tuple, which is possible
6871 from C code. Nor did object's tp_str consider that a type's tp_str
6872 could do something that could lead to an inifinite recursion.
6873 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6874 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006875
Georg Brandl3ee81df2008-05-17 18:14:43 +00006876- Issue #1164: It was possible to trigger deadlock when using the
6877 'print' statement to write to a file since the GIL was not released
6878 as needed. Now PyObject_Print() does the right thing along with
6879 various tp_print implementations of the built-in types and those in
6880 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006881
Georg Brandl3ee81df2008-05-17 18:14:43 +00006882- Issue #1147: Exceptions were directly allowing string exceptions in
6883 their throw() method even though string exceptions no longer
6884 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Issue #1096: Prevent a segfault from getting the repr of a very
6887 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006888
Brett Cannon1e534b52007-09-07 04:18:30 +00006889- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006890 PyObject_Call() never calling back out to Python code to trigger
6891 recursion depth updates/checks. Required the creation of a static
6892 RuntimeError instance in case normalizing an exception put the
6893 recursion check value past its limit. Fixes crashers
6894 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- Patch #1031213: Decode source line in SyntaxErrors back to its
6897 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00006898
Georg Brandl7c3b50d2007-07-12 08:38:00 +00006899- Patch #1673759: add a missing overflow check when formatting floats
6900 with %G.
6901
Georg Brandl3ee81df2008-05-17 18:14:43 +00006902- Prevent expandtabs() on string and unicode objects from causing a
6903 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006904
Georg Brandl3ee81df2008-05-17 18:14:43 +00006905- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006907- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00006908
Neal Norwitz0ac60192007-05-27 04:08:54 +00006909- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006910 __*__ attributes. (Some already existed, e.g., __doc__ and
6911 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006912
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006913- Add -3 option to the interpreter to warn about features that are
6914 deprecated and will be changed/removed in Python 3.0.
6915
Georg Brandl2134e752007-05-21 20:34:16 +00006916- Patch #1686487: you can now pass any mapping after '**' in function
6917 calls.
6918
Collin Winter62903052007-05-18 23:11:24 +00006919- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920 "except E as target:". This is to provide forwards compatibility
6921 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006922
Brett Cannon229cee22007-05-05 01:34:02 +00006923- Deprecate BaseException.message as per PEP 352.
6924
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006926 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006927
Vinay Sajip8549ce32007-05-06 17:53:37 +00006928- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006929 setting a plain string, ie don't expand to single letter identifiers.
6930
Raymond Hettinger13936692007-04-11 18:40:58 +00006931- Request #1191699: Slices can now be pickled.
6932
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006933- Request #1193128: str.translate() now allows a None argument for
6934 translations that only remove characters without re-mapping the
6935 remaining characters.
6936
Georg Brandl5cb76c12007-03-21 09:00:39 +00006937- Patch #1682205: a TypeError while unpacking an iterable is no longer
6938 masked by a generic one with the message "unpack non-sequence".
6939
Neal Norwitzaa754b72007-03-21 06:39:48 +00006940- Remove unused file Python/fmod.c.
6941
Guido van Rossum143b5642007-03-23 04:58:42 +00006942- Bug #1683368: The object.__init__() and object.__new__() methods are
6943 now stricter in rejecting excess arguments. The only time when
6944 either allows excess arguments is when it is not overridden and the
6945 other one is. For backwards compatibility, when both are
6946 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006947 warning later). Also, type.__init__() insists on the same signature
6948 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006949
Georg Brandl3ee81df2008-05-17 18:14:43 +00006950- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6951 object to complex using its __complex__() method before falling back
6952 to the __float__() method. Therefore, the functions in the cmath
6953 module now can operate on objects that define a __complex__()
6954 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006955
Georg Brandl3ee81df2008-05-17 18:14:43 +00006956- Patch #1623563: allow __class__ assignment for classes with
6957 __slots__. The old and the new class are still required to have the
6958 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Patch #1642547: Fix an error/crash when encountering syntax errors
6961 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00006962
Georg Brandl3ee81df2008-05-17 18:14:43 +00006963- Patch #1462488: Python no longer segfaults when
6964 ``object.__reduce_ex__()`` is called with an object that is faking
6965 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006966
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Patch #1680015: Don't modify __slots__ tuple if it contains an
6968 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00006969
Georg Brandl5240d742007-03-13 20:46:32 +00006970- Patch #1444529: the builtin compile() now accepts keyword arguments.
6971
Georg Brandl7b9c5552007-03-12 14:30:05 +00006972- Bug #1678647: write a newline after printing an exception in any
6973 case, even when converting the value to a string failed.
6974
Georg Brandl871f1bc2007-03-12 13:17:36 +00006975- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006976 its argument, if it exists. If not, it will work like before. This
6977 allows customizing the output of dir() in the presence of a
6978 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006979
Collin Winter276887b2007-03-12 16:11:39 +00006980- Patch #922167: Python no longer segfaults when faced with infinitely
6981 self-recursive reload() calls (as reported by bug #742342).
6982
Georg Brandl3ee81df2008-05-17 18:14:43 +00006983- Patch #1675981: remove unreachable code from ``type.__new__()``
6984 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006985
Georg Brandl3ee81df2008-05-17 18:14:43 +00006986- Patch #1491866: change the complex() constructor to allow
6987 parthensized forms. This means complex(repr(x)) now works instead of
6988 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006989
Georg Brandlaa2321b2007-03-07 00:40:28 +00006990- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006991 makes the filenames the warning module prints much more sensible

7500
Facundo Batistad918a652007-04-24 13:54:38 +00007501- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502 the client's request was successfully received, understood, and
7503 accepted. Now in these cases no error is raised in urllib (issue
7504 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007505

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007512- Added a timeout parameter to the constructor of other protocols
7513 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7514 work started with create_connection() and timeout in httplib, and
7515 closes patch #723312.
7516
Vinay Sajip8549ce32007-05-06 17:53:37 +00007517- Patch #1676823: Added create_connection() to socket.py, which may be
7518 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00007520
Martin v. Löwis0af33882007-03-23 13:27:15 +00007521- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7541
Georg Brandlf66b6032007-03-14 08:27:52 +00007542- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007543 AttributeError instead of an IOError when the server's response
7544 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007545
Georg Brandl3ee81df2008-05-17 18:14:43 +00007546- Patch #957650: "%var%" environment variable references are now
7547 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007549
Georg Brandl3ee81df2008-05-17 18:14:43 +00007550- Patch #1429539: pdb now correctly initializes the __main__ module
7551 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007552 correctly now.
7553
Georg Brandlbad6f192007-03-13 21:32:56 +00007554- The nonobvious commands.getstatus() function is now deprecated.

7560
Georg Brandl3ee81df2008-05-17 18:14:43 +00007561- Patch #1530482: add pydoc.render_doc() which returns the
7562 documentation for a thing instead of paging it to stdout, which
7563 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007564
Georg Brandl3ee81df2008-05-17 18:14:43 +00007565- Patch #1533909: the timeit module now accepts callables in addition

7571 parameter which can be set to False to prevent the default
7572 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007573
Georg Brandl9e6b4702007-03-13 18:15:41 +00007574- Patch #1581073: add a flag to textwrap that prevents the dropping of
7575 whitespace while wrapping.
7576
Georg Brandl92a6bae2007-03-13 17:43:32 +00007577- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007578 are set for invalid interpolation sequences that would lead to
7579 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007580

7593
Georg Brandl94fe3f52007-03-13 09:32:11 +00007594- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007595 field names in its exception message if you try to write a record
7596 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007614

7622 returned string up to the first NUL character.
7623

7633
Georg Brandl3ee81df2008-05-17 18:14:43 +00007634- unittest now verifies more of its assumptions. In particular,
7635 TestCase and TestSuite subclasses (not instances) are no longer
7636 accepted in TestSuite.addTest(). This should cause no
7637 incompatibility since it never made sense with ordinary subclasses
7638 -- the failure just occurred later, with a more cumbersome
7639 exception.

7648 given a unicode argument and os.listdir() returns unicode filenames.
7649
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650- Patch #1673619: setup.py identifies extension modules it doesn't

7652 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008028 time so that opening a database previously created with the DB_DUP
8029 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8030 opens. Specifically: dictionary assignment to a DB object will
8031 replace all values for a given key when the database allows
8032 duplicate values. DB users should use DB.put(k, v) when they want
8033 to store duplicates; not DB[k] = v.

8040 characters with ASCII value less than 32. Also, it correctly quotes
8041 dots only if they occur on a single line, as opposed to the previous
8042 behavior of quoting dots if they are the second character of any
8043 line.
