R David Murray20101872012-08-31 23:15:28 -0400878- Issue #12776,#11839: call argparse type function (specified by add_argument)
879 only once. Before, the type function was called twice in the case where the
880 default was specified and the argument was given as well. This was
881 especially problematic for the FileType type, as a default file would always
882 be opened, even if a file argument was specified on the command line.

1139 In particular, fix extension module build failures when trying to use
1140 32-bit-only installer Pythons on systems with Xcode 4 (currently
1141 OS X 10.8, 10.7, and optionally 10.6).
1142 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1143 * Since Xcode 4 removes ppc support, extension module builds now
1144 check for ppc compiler support and by default remove ppc and
1145 ppc64 archs when they are not available.
1146 * Extension module builds now revert to using system installed
1147 headers and libs (/usr and /System/Library) if the SDK used
1148 to build the interpreter is not installed or has moved.
1149 * Try to avoid building extension modules with deprecated
1150 and problematic Apple llvm-gcc compiler. If original compiler
1151 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001502- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1503 int.__pow__. These overflow checks were causing int.__pow__ to produce
1504 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001505 compiler optimizing the check away. Also fix similar overflow checks
1506 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1507 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001575- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001576 has left two versions of customize_compiler, the original in
1577 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001582- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1583 Distutils-based packages with C extension modules may fail because
1584 Apple has removed gcc-4.2, the version used to build python.org
1585 64-bit/32-bit Pythons. If the user does not explicitly override
1586 the default C compiler by setting the CC environment variable,
1587 Distutils will now attempt to compile extension modules with clang
1588 if gcc-4.2 is required but not found. Also as a convenience, if
1589 the user does explicitly set CC, substitute its value as the default
1590 compiler in the Distutils LDSHARED configuration variable for OS X.
1591 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1592 SDK, neither of which are available in Xcode 4. This change does not
1593 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001843- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1844 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1845 interpreter process. This could cause failures in non-Distutils subprocesses
1846 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001847 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001848 deployment target only in the environment of each build subprocess. It is
1849 still possible to globally override the default by setting
1850 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1851 greater or equal to the default value, the value with which the interpreter
1852 was built.

1882 the ticker doesn't have to wind down to zero from the old starting point
1883 before the new interval takes effect. And if the user increases the
1884 interval, it makes sure the new limit takes effect right away rather have an
1885 early task switch before recognizing the new interval.

2866 This prevents user-created self-referencing ordered dictionaries from
2867 becoming permanently uncollectable GC garbage. The downside is that
2868 removing __del__ means that the internal doubly-linked list has to wait for
2869 GC collection rather than freeing memory immediately when the refcnt drops
2870 to zero.

2878 to fetch the original errno, or to filter timeout errors. Now the
2879 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003329- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3330 start byte and the continuation byte(s) are now considered invalid, instead
3331 of the number of bytes specified by the start byte.
3332 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3333 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3334 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003343- Issue #8748: Fix two issues with comparisons between complex and integer
3344 objects. (1) The comparison could incorrectly return True in some cases
3345 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3346 (2) The comparison raised an OverflowError for large integers, leading
3347 to unpredictable exceptions when combining integers and complex objects
3348 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00003730- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3731 with a non-empty format string. This is an effort to future-proof user
3732 code. If a derived class does not currently implement __format__ but later
3733 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003734 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003735 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitroud840e512010-02-04 20:20:18 +00004220- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004221 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004222 Also, raise ValueError rather than TypeError when an unknown TIPC address
4223 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004227- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004228 file position when calling `truncate()`. It would previously change the file
4229 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004230 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4231
Georg Brandlba83f822010-03-14 09:50:54 +00004232- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4233 class used to represent files stored inside an archive. The new
4234 implementation is significantly faster and can be wrapped in a
4235 ``io.BufferedReader`` object for more speedups. It also solves an issue
4236 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004246
Georg Brandlba83f822010-03-14 09:50:54 +00004247- Issue #7748: Since unicode values are supported for some metadata options in
4248 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4249 encoded string for them. This ensures that the upload and register commands
4250 send the correct values to PyPI without any error.

4325-----------------
4326
Georg Brandlba83f822010-03-14 09:50:54 +00004327- The ``__complex__()`` method is now looked up on the class of instances to
4328 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004330- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4331 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4332
Mark Dickinson1b34d252010-01-01 17:27:30 +00004333- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004334 DeprecationWarning when passed a float argument where an integer was expected.
4335 These functions and methods now raise TypeError instead. The majority of the
4336 effects of this change are in the extension modules, but some core functions
4337 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4338 and many unicode/str methods.

4352 of integers: the result of a/b is now correctly rounded for ints a and b (at
4353 least on IEEE 754 platforms), and in particular does not depend on the
4354 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004361 executables on OSX.
4362
Georg Brandlba83f822010-03-14 09:50:54 +00004363 These executables now work properly with the arch(1) command: ``arch -ppc
4364 python`` will start a universal binary version of python in PPC mode (unlike
4365 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004521- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4522 decimal string that's guaranteed to round back to x under correct rounding
4523 (with round-half-to-even rounding mode). Previously it gave a string based on
4524 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4525 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4526 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004527
Georg Brandlba83f822010-03-14 09:50:54 +00004528- Issue #7117: On almost all platforms: float-to-string and string-to-float
4529 conversions within Python are now correctly rounded. Places these conversions
4530 occur include: str for floats and complex numbers; the float and complex
4531 constructors; old-style and new-style numeric formatting; serialization and
4532 deserialization of floats and complex numbers using marshal, pickle and json;
4533 parsing of float and imaginary literals in Python code; Decimal-to-float
4534 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004535
Georg Brandlba83f822010-03-14 09:50:54 +00004536 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4537 providing correctly-rounded strtod and dtoa C functions. This code is
4538 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4539 the C compiler. There may be a small number of platforms on which correct
4540 operation of this code cannot be guaranteed, so the code is not used: notably,
4541 this applies to platforms where the C double format is not IEEE 754 binary64,
4542 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4543 and Python's configure script is unable to determine how to change the FPU
4544 precision. On these platforms conversions use the platform strtod and dtoa,
4545 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004547- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4548 uses the correctly-rounded string <-> float conversions described above (when
4549 available), and so produces correctly rounded results that will display nicely
4550 under the float repr. There are two related small changes: (1) round now
4551 accepts any class with an ``__index__()`` method for its second argument (but
4552 no longer accepts floats for the second argument), and (2) an excessively
4553 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4554 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004701- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4702 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4703 but with at least one decimal point and with a default precision
4704 of 12. Previously, the behavior the same but with a default precision of 6.
4705 This more closely matches ``str()``, and reduces surprises when adding
4706 alignment flags to the empty presentation type. This also affects the new
4707 complex.__format__ in the same way.
4708

Georg Brandlba83f822010-03-14 09:50:54 +00004905- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4906 file objects with closefd=False. The file descriptor is still kept open but
4907 the file object behaves like a closed file. The ``FileIO`` object also got a
4908 new readonly attribute ``closefd``.

4933 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00004959- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4960 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4961 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4962 of using the replace error handler in PyUnicode_DecodeUTF8().
4963
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004964- Issue #3739: The unicode-internal encoder now reports the number of characters

4966
Georg Brandlba83f822010-03-14 09:50:54 +00004967- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4969 gives improved memory leak detection when running under Valgrind, while taking
4970 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006338- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6339
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006340- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6341 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6342 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6343 ``printf`` function, whereas PyString_FromFormat has an independent
6344 implementation and uses "%zd" on all platforms for size_t values.
6345 This makes a difference on win64, where ``printf`` needs "%Id" to display
6346 64bit values.
6347
Benjamin Peterson97179b02008-09-09 20:55:01 +00006348- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6352 object; previously an int would be returned for small values. the __long__
6353 method is allowed to return either an int or a long, but the behaviour of
6354 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006356- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006362 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006363 was correctly parsed but parsing of subsequent arguments failed.
6364
Vinay Sajip35e3b032008-09-01 14:33:59 +00006365- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006366 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6367 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6368 when given a tuple of classes as second argument, were looking up
6369 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6370 type object.
6371

6515-----------------
6516
Guido van Rossumf8402962008-08-20 15:01:50 +00006517- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6518 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6519 extensions do not automatically benefit from the class attribute
6520 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6521 to their tp_flags field if they care. This is a backwards
6522 compatibility feature; in 3.0, all types will use the cache by
6523 default.
6524
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006525- Keyword arguments can now follow starred arguments. (``f(a, *args,
6526 keyword=23)`` is now valid syntax.)
6527
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006528- ctypes function pointers that are COM methods have a boolean True
6529 value again.
6530
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006531- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6532 by denying s# to parse objects that have a releasebuffer procedure,
6533 and introducing s*.
6534
Georg Brandl1e13ea92008-08-11 09:07:59 +00006535- Issue #3537: Fix an assertion failure when an empty but presized dict
6536 object was stored in the freelist.
6537
Mark Dickinsonb6467572008-08-04 21:30:09 +00006538- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6539 ValueError consistently across platforms.
6540
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006541- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6542 (64bit Unix, for example), unichr() would truncate its argument and return
6543 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6544
Neal Norwitze7d8be82008-07-31 17:17:14 +00006545- Apply security patches from Apple.
6546
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006547- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6548 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6549
Antoine Pitrou92f82162008-07-25 22:22:08 +00006550- Issue #1819: function calls with several named parameters are now on
6551 average 35% faster (as measured by pybench).
6552
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006553- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6554 the python debugger steps into a class statement: the free variables (local
6555 variables defined in an outer scope) would be deleted from the outer scope.
6556
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006557- Issue #2620: Overflow checking when allocating or reallocating memory
6558 was not always being done properly in some python types and extension
6559 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6560 all been updated to perform better checks and places in the code that
6561 would previously leak memory on the error path when such an allocation

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006567- Issue #3612: Added some missing basic types in ctypes.wintypes.
6568
Benjamin Petersone977ad42008-08-20 01:42:01 +00006569- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6570 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6571
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006572- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6573 version reported by these tools does not necessarily follow the python
6574 version numbering scheme, so the module is less strict when parsing it.
6575
Nick Coghlanf70385a2008-08-18 12:42:46 +00006576- Issue #2235: Added Py3k warnings for types which will become unhashable
6577 under the stricter __hash__ inheritance rules in 3.0. Several types
6578 which did not meet the rules for hash invariants and were already
6579 unhashable in 3.0 have now been explicitly flagged as unhashable in
6580 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6581 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6582
Brett Cannon88f801d2008-08-18 00:46:22 +00006583- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6584 imported into the module but exposed as part of the module's API.
6585
Brett Cannon7b96f072008-08-18 00:41:11 +00006586- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006590- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6591
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006592- Issue #3575: Incremental decoder's decode function now takes bytearray
6593 by using 's*' instead of 't#'.
6594
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006595- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006596 fails unicode conversion on 2nd parameter. (windows only)
6597
Georg Brandl222e2082010-08-01 22:27:39 +00006598- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006599 in a redirect.
6600
Brett Cannonabe423e2008-08-16 21:47:07 +00006601- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006602 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006603
Facundo Batistaeb90b782008-08-16 14:44:07 +00006604- Issue #2776: fixed small issue when handling an URL with double slash
6605 after a 302 response in the case of not going through a proxy.
6606
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006607- Issue #2676: in the email package, content-type parsing was hanging on
6608 pathological input because of quadratic or exponential behaviour of a
6609 regular expression.
6610
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006611- Issue #3476: binary buffered reading through the new "io" library is now
6612 thread-safe.
6613
Brett Cannonbf3157b2008-08-14 05:00:03 +00006614- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6615 since mimetools itself is deprecated. Because modules are cached, all
6616 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6617
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006618- Issue #3134: shutil referenced undefined WindowsError symbol.
6619
Robert Schuppenies14646332008-08-10 11:01:53 +00006620- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6621 menu entries were not deleted.
6622
Brett Cannon83e81842008-08-09 23:30:55 +00006623- Copied the implementation of reduce() to _functools.reduce() to have a
6624 version that did not raise a DeprecationWarning under -3.
6625
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006626- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6627 a MemoryError rather than silently stop the iteration.
6628
Guido van Rossum59ce9012008-08-09 14:55:34 +00006629- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6630 to _sre.compile() will now be rejected. This should not affect anybody
6631 since the re.compile() function never generates invalid re-bytecode.
6632
Skip Montanaroa032bf42008-08-08 22:52:51 +00006633- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6634 upon first access it can be automatically initialized from the csv file if
6635 it wasn't initialized during instantiation.
6636
Brett Cannon3aa2a492008-08-06 22:28:09 +00006637- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6638 the reload() built-in has been removed.
6639
Brett Cannon7e30b672008-08-04 21:52:25 +00006640- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006641 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6649 raised an AttributeError.
6650
Benjamin Peterson01a24322008-07-28 23:35:27 +00006651- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006652 asking for a specific length. This problem only affected files opened
6653 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006654
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006655- Issue #3449: Update decimal module to use most recent specification
6656 (v. 1.68) and tests (v. 2.58) from IBM.
6657
Georg Brandl222e2082010-08-01 22:27:39 +00006658- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006678- Issue #3394: zipfile.writestr sets external attributes when passed a
6679 file name rather than a ZipInfo instance, so files are extracted with
6680 mode 0600 rather than 000 under Unix.
6681
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006682- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6683 argument in python 2.5, this broke code that subclassed Popen to include its
6684 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006694- Issue #2235: the C API function PyObject_HashNotImplemented and its
6695 interaction with the tp_hash slot (added in 2.6b2) are now documented
6696
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006697- Issue #643841: The language reference now provides more detailed
6698 coverage of the lookup process for special methods. The disclaimers
6699 regarding lack of coverage of new-style classes have also been
6700 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006708Core and Builtins
6709-----------------
6710
Georg Brandl3e483f62008-07-16 22:57:41 +00006711- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6712 its methods now allow for items objects that can be converted to
6713 an integer using operator.index().
6714
Mark Dickinson64b7e502008-07-16 09:40:03 +00006715- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6716 produced a ValueError instead of giving the correct float.
6717
Eric Smitha5fa5a22008-07-16 00:11:49 +00006718- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6719 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6720
Mark Dickinson7103aa42008-07-15 19:08:33 +00006721- Issue #3008: the float type has a new instance method 'float.hex'
6722 and a new class method 'float.fromhex' to convert floating-point
6723 numbers to and from hexadecimal strings, respectively.
6724
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006725- Issue #2235: __hash__ is once again inherited by default. To allow
6726 collections.Hashable to remain meaningful in the presence of the
6727 default hash implementation (object.__hash__), it is now possible
6728 to explicit block inheritance of hash by setting __hash__=None at
6729 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6730 level.
6731
Nick Coghlanb028f502008-07-13 14:52:36 +00006732- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6733 the parent module cannot be found while performing an absolute import.
6734 This means that an incorrectly defined __package__ attribute will
6735 now only prevent relative imports in that module rather than causing
6736 all imports from that module to fail.
6737
Nick Coghlan14ff9942008-07-08 14:21:42 +00006738- Issue #2517: Allow unicode messages in Exceptions again by correctly
6739 bypassing the instance dictionary when looking up __unicode__ on
6740 new-style classes.
6741
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006742- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6743 set to a custom object whose write() method happens to install
6744 another file in sys.stdout.
6745
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006746- Issue #3088: Corrected a race condition in classes derived from
6747 threading.local: the first member set by a thread could be saved in
6748 another thread's dictionary.
6749
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006750- Issue #3004: Minor change to slice.indices(): the start and stop
6751 arguments are now treated identically, making the behaviour easier
6752 to describe and understand. For example, slice(None, -10,
6753 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6754 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6755 10, -1).
6756
Georg Brandl278fc502008-07-19 12:46:12 +00006757- Issue #3219: Calling a function with repeated keyword arguments,
6758 f(a=2, a=23), would not cause a syntax error. This was a regression
6759 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006760
Georg Brandl278fc502008-07-19 12:46:12 +00006761- Issue #2862: Make int and float freelist management consistent with
6762 other freelists. Changes their CompactFreeList apis into
6763 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006764

6766-------
6767
Thomas Heller57adf222008-08-14 19:10:48 +00006768- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6769 api functions without holding the GIL, which could lead to a fatal
6770 error when they failed.
6771
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006772- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
6773
Jesse Noller7fb96402008-07-17 21:01:05 +00006774- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

Jesse Noller13e9d582008-07-16 14:32:36 +00006780- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6781 ForkingPickler.register() to resolve conflict with ctypes.
6782
Vinay Sajip51e65192008-07-18 09:01:10 +00006783- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006784
Thomas Heller880f5292008-07-15 19:39:38 +00006785- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6786 a valid dlerror() message.
6787
Thomas Heller2bad6572008-07-15 17:19:50 +00006788- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6789 incomplete structure was created.
6790

6794
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006795- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006796
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006797- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6798 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006799 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006800 content-length. The problem had been corrected in the 2.4 branch, but never
6801 merged into trunk.
6802
Georg Brandle78fbcc2008-07-05 10:13:36 +00006803- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00006815
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006816- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6817 handling is now the same as that of other special attributes like __name__).
6818
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006819- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6820 removal in Python 3.0 in favor of urllib2.urlopen().

6831 default https port (443).
6832
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00006833- Issue #874900: after an os.fork() call the threading module state is cleaned

7208 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007209 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007210
7211 This is controlled by the configure argument ``--with-universal-archs``:
7212
7213 - ``--with-universal-archs=all``: install 4-way universal
7214
7215 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7216
7217 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7218
7219 This option should be used in combination with ``--enable-universalsdk=``.
7220
7221 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007271- Issue #1631171: Re-implement the 'warnings' module in C (the
7272 original Python code has been kept as backup). This will allow for
7273 using the 'warning's machinery in such places as the parser where
7274 use of pure Python code is not possible. Both the ``showarning()``
7275 and ``formatwarning()`` gain an optional 'line' argument which is
7276 not called by default for backwards-compatibility reasons. Setting
7277 ``warnings.showwarning()`` to an implementation that lacks support
7278 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007341- Issue #2550: The approach used by client/server code for obtaining
7342 ports to listen on in network-oriented tests has been refined in an
7343 effort to facilitate running multiple instances of the entire
7344 regression test suite in parallel without issue.
7345 test_support.bind_port() has been fixed such that it will always
7346 return a unique port -- which wasn't always the case with the
7347 previous implementation, especially if socket options had been set
7348 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7349 new implementation of bind_port() will actually raise an exception
7350 if it is passed an AF_INET/SOCK_STREAM socket with either the
7351 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7352 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7353 the socket it's been passed. This currently only applies to
7354 Windows. This option prevents any other sockets from binding to the
7355 host/port we've bound to, thus removing the possibility of the
7356 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7357 when a second SOCK_STREAM socket binds and accepts to a host/port
7358 that's already been bound by another socket. The optional preferred
7359 port parameter to bind_port() has been removed. Under no
7360 circumstances should tests be hard coding ports!
7361
7362 test_support.find_unused_port() has also been introduced, which will
7363 pass a temporary socket object to bind_port() in order to obtain an
7364 unused port. The temporary socket object is then closed and
7365 deleted, and the port is returned. This method should only be used
7366 for obtaining an unused port in order to pass to an external program
7367 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7368 a parameter to a server-oriented class that doesn't give you direct
7369 access to the underlying socket used.
7370
7371 Finally, test_support.HOST has been introduced, which should be used
7372 for the host argument of any relevant socket calls (i.e. bind and
7373 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007374
7375 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007377 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7378 test_asynchat and test_socket_ssl.
7379
Georg Brandl3ee81df2008-05-17 18:14:43 +00007380 It is now possible for multiple instances of the regression test
7381 suite to run in parallel without issue.

7655- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007656
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007657- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007658 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007659
Eric Smitha73fbe72008-02-23 03:09:44 +00007660- Added the future_builtins module, which contains hex() and oct().
7661 These are the PEP 3127 version of these functions, designed to be
7662 compatible with the hex() and oct() builtins from Python 3.0. They
7663 differ slightly in their output formats from the existing, unchanged
7664 Python 2.6 builtins. The expected usage of the future_builtins
7665 module is:
7666 from future_builtins import hex, oct
7667
Eric Smith7ef40bf2008-02-20 23:34:22 +00007668- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7669 exponents for exponents with absolute value < 100. Follows C99
7670 standard. This is a change on Windows, which would use 3 digits.
7671 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7672 so that any alterations it does to the resulting string will be
7673 available in stringlib/formatter.h (for float.__format__).
7674
Eric Smith5a3c1352008-02-19 13:21:56 +00007675- Implemented PEP 3101, Advanced String Formatting. This adds a new
7676 builtin format(); a format() method for str and unicode; a
7677 __format__() method to object, str, unicode, int, long, float, and
7678 datetime; the class string.Formatter; and the C API
7679 PyObject_Format().
7680
Georg Brandl3ee81df2008-05-17 18:14:43 +00007681- Fixed several potential crashes, all caused by specially crafted
7682 __del__ methods exploiting objects in temporarily inconsistent
7683 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007684
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007685- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007686 prevent a possible crash: an Abstract Base Class would try to access
7687 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007688
Georg Brandl3ee81df2008-05-17 18:14:43 +00007689- Fixed repr() and str() of complex numbers with infinity or nan as
7690 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Clear all free lists during a gc.collect() of the highest generation
7693 in order to allow pymalloc to free more arenas. Python may give back
7694 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007695
Georg Brandl3ee81df2008-05-17 18:14:43 +00007696- Issue #2045: Fix an infinite recursion triggered when printing a
7697 subclass of collections.defaultdict, if its default_factory is set
7698 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007699
Christian Heimesf75dbef2008-02-08 00:11:31 +00007700- Fixed a minor memory leak in dictobject.c. The content of the free
7701 list was not freed on interpreter shutdown.
7702
Georg Brandl21e99f42010-03-07 15:23:59 +00007703- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007704 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7707 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007708 to compact the internal free lists of pre-allocted ints and floats.
7709
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7711 calls. Python expected the return type int but the fork familie
7712 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007713
Georg Brandl3ee81df2008-05-17 18:14:43 +00007714- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7715 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007723- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7724 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007725
Georg Brandl3ee81df2008-05-17 18:14:43 +00007726- Patch #1473257: generator objects gain a gi_code attribute. This is
7727 the same object as the func_code attribute of the function that
7728 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007729
Georg Brandl3ee81df2008-05-17 18:14:43 +00007730- Issue #1920: "while 0" statements were completely removed by the
7731 compiler, even in the presence of an "else" clause, which is
7732 supposed to be run when the condition is false. Now the compiler
7733 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007734
Guido van Rossumeead05f2008-01-24 18:21:02 +00007735- A few crashers fixed: weakref_in_del.py (issue #1377858);
7736 loosing_dict_ref.py (issue #1303614, test67.py);
7737 borrowed_ref_[34].py (not in tracker).
7738
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007739- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007740 suppressed while an extension is loaded by calling SetErrorMode in
7741 dynload_win.c. The error is still reported properly.
7742
Georg Brandl3ee81df2008-05-17 18:14:43 +00007743- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007744 several extension methods and modules do not work without unicode
7745 support.
7746
Georg Brandl26543b12008-01-21 18:36:51 +00007747- Issue #1882: when compiling code from a string, encoding cookies in the
7748 second line of code were not always recognized correctly.
7749
Georg Brandl14404b62008-01-19 19:27:05 +00007750- Issue #1679: "0x" was taken as a valid integer literal.
7751
Georg Brandl6caad7d2008-01-26 14:19:22 +00007752- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007753 added.
7754
Christian Heimesc94e2b52008-01-14 04:13:37 +00007755- sys.float_info / PyFloat_GetInfo: The floating point information
7756 object was converted from a dict to a specialized structseq object.
7757
Georg Brandl3ee81df2008-05-17 18:14:43 +00007758- Patch #1816: Added sys.flags structseq. It exposes the status of
7759 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007760
Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Objects/structseq.c: Implemented new structseq representation. The
7762 patch makes structseqs (e.g. the return value of os.stat) more
7763 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007764
Georg Brandl3ee81df2008-05-17 18:14:43 +00007765- Patch #1700288: added a type attribute cache that caches method
7766 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007767
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007768- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +00007771- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7774 envvar and sys.dont_write_bytecode attribute. All these can be set
7775 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007776
Georg Brandl3ee81df2008-05-17 18:14:43 +00007777- Improve some exception messages when Windows fails to load an
7778 extension module. Now we get for example '%1 is not a valid Win32
7779 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007786- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007787 and INF. float("nan"), float("inf") and float("-inf") now work on
7788 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007789
Georg Brandl3ee81df2008-05-17 18:14:43 +00007790- Compiler now generates simpler and faster code for dictionary
7791 literals. The oparg for BUILD_MAP now indicates an estimated
7792 dictionary size. There is a new opcode, STORE_MAP, for adding
7793 entries to the dictionary.

7836
Georg Brandl21e99f42010-03-07 15:23:59 +00007837- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7839 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007840
Georg Brandl3ee81df2008-05-17 18:14:43 +00007841- Issue #1686386: Tuple's tp_repr did not take into account the
7842 possibility of having a self-referential tuple, which is possible
7843 from C code. Nor did object's tp_str consider that a type's tp_str
7844 could do something that could lead to an inifinite recursion.
7845 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7846 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007847
Georg Brandl3ee81df2008-05-17 18:14:43 +00007848- Issue #1164: It was possible to trigger deadlock when using the
7849 'print' statement to write to a file since the GIL was not released
7850 as needed. Now PyObject_Print() does the right thing along with
7851 various tp_print implementations of the built-in types and those in
7852 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007853
Georg Brandl3ee81df2008-05-17 18:14:43 +00007854- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007861- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007862 PyObject_Call() never calling back out to Python code to trigger
7863 recursion depth updates/checks. Required the creation of a static
7864 RuntimeError instance in case normalizing an exception put the
7865 recursion check value past its limit. Fixes crashers

7887
Georg Brandl2134e752007-05-21 20:34:16 +00007888- Patch #1686487: you can now pass any mapping after '**' in function
7889 calls.
7890
Collin Winter62903052007-05-18 23:11:24 +00007891- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007892 "except E as target:". This is to provide forwards compatibility
7893 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007897- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007898 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007899
Vinay Sajip8549ce32007-05-06 17:53:37 +00007900- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007901 setting a plain string, ie don't expand to single letter identifiers.
7902
Raymond Hettinger13936692007-04-11 18:40:58 +00007903- Request #1191699: Slices can now be pickled.
7904
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007905- Request #1193128: str.translate() now allows a None argument for
7906 translations that only remove characters without re-mapping the
7907 remaining characters.
7908
Georg Brandl5cb76c12007-03-21 09:00:39 +00007909- Patch #1682205: a TypeError while unpacking an iterable is no longer
7910 masked by a generic one with the message "unpack non-sequence".

Neal Norwitzaa754b72007-03-21 06:39:48 +00007912- Remove unused file Python/fmod.c.
7913
Guido van Rossum143b5642007-03-23 04:58:42 +00007914- Bug #1683368: The object.__init__() and object.__new__() methods are
7915 now stricter in rejecting excess arguments. The only time when
7916 either allows excess arguments is when it is not overridden and the
7917 other one is. For backwards compatibility, when both are
7918 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007919 warning later). Also, type.__init__() insists on the same signature
7920 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007921
Georg Brandl3ee81df2008-05-17 18:14:43 +00007922- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7923 object to complex using its __complex__() method before falling back
7924 to the __float__() method. Therefore, the functions in the cmath
7925 module now can operate on objects that define a __complex__()
7926 method.

7943
Georg Brandl7b9c5552007-03-12 14:30:05 +00007944- Bug #1678647: write a newline after printing an exception in any
7945 case, even when converting the value to a string failed.
7946
Georg Brandl871f1bc2007-03-12 13:17:36 +00007947- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948 its argument, if it exists. If not, it will work like before. This
7949 allows customizing the output of dir() in the presence of a
7950 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007951
Collin Winter276887b2007-03-12 16:11:39 +00007952- Patch #922167: Python no longer segfaults when faced with infinitely
7953 self-recursive reload() calls (as reported by bug #742342).
7954

7959 parthensized forms. This means complex(repr(x)) now works instead of
7960 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007961
Georg Brandlaa2321b2007-03-07 00:40:28 +00007962- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963 makes the filenames the warning module prints much more sensible
7964 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007965

Georg Brandl0fca97a2007-03-05 22:28:08 +00007977- Patch #1674228: when assigning a slice (old-style), check for the
7978 sq_ass_slice instead of the sq_slice slot.
7979
Georg Brandl3ee81df2008-05-17 18:14:43 +00007980- When printing an unraisable error, don't print exceptions. before
7981 the name. This duplicates the behavior whening normally printing
7982 exceptions.

7991 created a weakref on itself during a __del__ call for new-style
7992 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00008032- Bug #1545497: when given an explicit base, int() did ignore NULs
8033 embedded in the string to convert.
8034
Georg Brandl846f73a2006-10-08 07:11:54 +00008035- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008083 generator expressions (x for x, in ... ) works again. Fixing this
8084 problem required changing the .pyc magic number. This means that
8085 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008886- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8887 with RFC 3207 and forgets any knowledge obtained from the server not
8888 obtained from the TLS negotiation itself. Patch contributed by Bill
8889 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008890
Georg Brandl3ee81df2008-05-17 18:14:43 +00008891- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008892 that the SMTP.starttls() caller no longer needs to call ehlo()
8893 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008894 does not claim to support starttls. Adds the
8895 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8976 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8977 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008994 time so that opening a database previously created with the DB_DUP
8995 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8996 opens. Specifically: dictionary assignment to a DB object will
8997 replace all values for a given key when the database allows
8998 duplicate values. DB users should use DB.put(k, v) when they want
8999 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009000

9006 characters with ASCII value less than 32. Also, it correctly quotes
9007 dots only if they occur on a single line, as opposed to the previous
9008 behavior of quoting dots if they are the second character of any
9009 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009010
