Ned Deily18fae3f2013-01-31 01:24:55 -08001319- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1320 In particular, fix extension module build failures when trying to use
1321 32-bit-only installer Pythons on systems with Xcode 4 (currently
1322 OS X 10.8, 10.7, and optionally 10.6).
1323 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1324 * Since Xcode 4 removes ppc support, extension module builds now
1325 check for ppc compiler support and by default remove ppc and
1326 ppc64 archs when they are not available.
1327 * Extension module builds now revert to using system installed
1328 headers and libs (/usr and /System/Library) if the SDK used
1329 to build the interpreter is not installed or has moved.
1330 * Try to avoid building extension modules with deprecated
1331 and problematic Apple llvm-gcc compiler. If original compiler
1332 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001756- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001757 has left two versions of customize_compiler, the original in
1758 distutils.sysconfig and another copy in distutils.ccompiler, with some
1759 parts of distutils calling one and others using the other.
1760 Complete the revert back to only having one in distutils.sysconfig as
1761 is the case in 3.x.
1762
Ned Deily0d0ea482012-02-10 12:59:06 +01001763- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1764 Distutils-based packages with C extension modules may fail because
1765 Apple has removed gcc-4.2, the version used to build python.org
1766 64-bit/32-bit Pythons. If the user does not explicitly override
1767 the default C compiler by setting the CC environment variable,
1768 Distutils will now attempt to compile extension modules with clang
1769 if gcc-4.2 is required but not found. Also as a convenience, if
1770 the user does explicitly set CC, substitute its value as the default
1771 compiler in the Distutils LDSHARED configuration variable for OS X.
1772 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1773 SDK, neither of which are available in Xcode 4. This change does not
1774 attempt to override settings to support their use with Xcode 4.)

2025 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2026 interpreter process. This could cause failures in non-Distutils subprocesses
2027 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002028 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002029 deployment target only in the environment of each build subprocess. It is
2030 still possible to globally override the default by setting
2031 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2032 greater or equal to the default value, the value with which the interpreter
2033 was built.

2062 updating the check interval, so if the user decreases the check interval,
2063 the ticker doesn't have to wind down to zero from the old starting point
2064 before the new interval takes effect. And if the user increases the
2065 interval, it makes sure the new limit takes effect right away rather have an
2066 early task switch before recognizing the new interval.

3507-----------------
3508
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003509- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3510 start byte and the continuation byte(s) are now considered invalid, instead
3511 of the number of bytes specified by the start byte.
3512 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3513 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3514 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3515 Previous versions returned a single u'\ufffd'.
3516
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003517- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003518 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3519 arises from the "Overriding __eq__ blocks inheritance ..." warning
3520 when turned into an exception: in this case the exception simply
3521 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003522
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003523- Issue #8748: Fix two issues with comparisons between complex and integer
3524 objects. (1) The comparison could incorrectly return True in some cases
3525 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3526 (2) The comparison raised an OverflowError for large integers, leading
3527 to unpredictable exceptions when combining integers and complex objects
3528 in sets or dicts.
3529
Mark Dickinson81336372010-05-30 12:12:25 +00003530- Issue #5211: Implicit coercion for the complex type is now completely
3531 removed. (Coercion for arithmetic operations was already removed in 2.7
3532 alpha 4, but coercion for rich comparisons was accidentally left in.)
3533
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003534- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3535 and error handler, instead of writing to the C stderr file in utf-8
3536
Georg Brandlfee0f442010-05-22 21:26:21 +00003537- Issue #7902: When using explicit relative import syntax, don't try implicit
3538 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00003539
Georg Brandlfee0f442010-05-22 21:26:21 +00003540- Issue #7079: Fix a possible crash when closing a file object while using it
3541 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00003543- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00003544 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00003549- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
3550 of the interpreter to set sys.argv without also modifying sys.path. This
3551 helps fix `CVE-2008-5983

3669 using its __int__ method. Previously, only small arguments were treated this

3898 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00003910- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3911 with a non-empty format string. This is an effort to future-proof user
3912 code. If a derived class does not currently implement __format__ but later
3913 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003914 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003915 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00004286- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00004287 thread could raise an incorrect RuntimeError about not holding the import
4288 lock. The import lock is now reinitialized after fork.

4301 common TestCase for some tests: test_genericpath.CommonTest.
4302
Georg Brandlba83f822010-03-14 09:50:54 +00004303- Print platform information when running the whole test suite, or using the
4304 ``--verbose`` flag.

Georg Brandlba83f822010-03-14 09:50:54 +00004309- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004310 is run with the -OO flag. Tests requiring docstrings are skipped.
4311
Georg Brandlba83f822010-03-14 09:50:54 +00004312- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4313 now also used by regrtest to run all the tests in a temporary directory. The
4314 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4315 Xicluna who helped with the patch.

4332 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004333 library would return a bogus result; on Solaris, it was possible to crash the
4334 interpreter. Patch by Stefan Krah.

4345 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00004346
Georg Brandlba83f822010-03-14 09:50:54 +00004347- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4348 and add the additional members returned in an OSVERSIONINFOEX structure. The
4349 new members are service_pack_major, service_pack_minor, suite_mask, and
4350 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00004351
Georg Brandlba83f822010-03-14 09:50:54 +00004352- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4353 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4354 returning NULL. The macro now returns a statically allocated empty string
4355 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00004356
Antoine Pitrou64672132010-01-13 07:55:48 +00004357- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00004364 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4365 strings,
4366 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4367 numeric strings corresponding to subnormal values,
4368 (3) a memory leak for some values large enough to cause overflow, and
4369 (4) a number of flaws that could lead to incorrectly rounded results.
4370

4372 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00004373

R. David Murray63e4fd72010-02-10 22:42:04 +00004386- Issue #7835: shelve should no longer produce mysterious warnings during
4387 interpreter shutdown.
4388
Georg Brandlba83f822010-03-14 09:50:54 +00004389- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4390 XML processing instructions and comments. These raw characters are allowed
4391 by the XML specification, and are necessary when outputting e.g. PHP code in
4392 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +00004399
Antoine Pitroud840e512010-02-04 20:20:18 +00004400- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004401 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004402 Also, raise ValueError rather than TypeError when an unknown TIPC address
4403 type is specified. Patch by Brian Curtin.
4404
Vinay Sajip28c382f2010-02-04 18:48:53 +00004405- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004407- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004408 file position when calling `truncate()`. It would previously change the file
4409 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004410 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4411
Georg Brandlba83f822010-03-14 09:50:54 +00004412- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4413 class used to represent files stored inside an archive. The new
4414 implementation is significantly faster and can be wrapped in a
4415 ``io.BufferedReader`` object for more speedups. It also solves an issue
4416 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4417 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00004418
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004419- Issue #7792: Registering non-classes to ABCs raised an obscure error.

4425 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004426
Georg Brandlba83f822010-03-14 09:50:54 +00004427- Issue #7748: Since unicode values are supported for some metadata options in
4428 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4429 encoded string for them. This ensures that the upload and register commands
4430 send the correct values to PyPI without any error.

4505-----------------
4506
Georg Brandlba83f822010-03-14 09:50:54 +00004507- The ``__complex__()`` method is now looked up on the class of instances to
4508 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004509
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004510- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4512
Mark Dickinson1b34d252010-01-01 17:27:30 +00004513- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004514 DeprecationWarning when passed a float argument where an integer was expected.
4515 These functions and methods now raise TypeError instead. The majority of the
4516 effects of this change are in the extension modules, but some core functions
4517 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4518 and many unicode/str methods.

4530
Georg Brandlba83f822010-03-14 09:50:54 +00004531- Issue #1811: Improve accuracy and cross-platform consistency for true division
4532 of integers: the result of a/b is now correctly rounded for ints a and b (at
4533 least on IEEE 754 platforms), and in particular does not depend on the
4534 internal representation of a long.

4542
Georg Brandlba83f822010-03-14 09:50:54 +00004543 These executables now work properly with the arch(1) command: ``arch -ppc
4544 python`` will start a universal binary version of python in PPC mode (unlike

4691 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004700- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4701 decimal string that's guaranteed to round back to x under correct rounding
4702 (with round-half-to-even rounding mode). Previously it gave a string based on
4703 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4704 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4705 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004707- Issue #7117: On almost all platforms: float-to-string and string-to-float
4708 conversions within Python are now correctly rounded. Places these conversions
4709 occur include: str for floats and complex numbers; the float and complex
4710 constructors; old-style and new-style numeric formatting; serialization and
4711 deserialization of floats and complex numbers using marshal, pickle and json;
4712 parsing of float and imaginary literals in Python code; Decimal-to-float
4713 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004714
Georg Brandlba83f822010-03-14 09:50:54 +00004715 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4716 providing correctly-rounded strtod and dtoa C functions. This code is
4717 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4718 the C compiler. There may be a small number of platforms on which correct
4719 operation of this code cannot be guaranteed, so the code is not used: notably,
4720 this applies to platforms where the C double format is not IEEE 754 binary64,
4721 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4722 and Python's configure script is unable to determine how to change the FPU
4723 precision. On these platforms conversions use the platform strtod and dtoa,
4724 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004726- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4727 uses the correctly-rounded string <-> float conversions described above (when
4728 available), and so produces correctly rounded results that will display nicely
4729 under the float repr. There are two related small changes: (1) round now
4730 accepts any class with an ``__index__()`` method for its second argument (but
4731 no longer accepts floats for the second argument), and (2) an excessively
4732 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4733 raises an exception.

4960 internal representation of integers, for performance reasons. Base 2**30 is
4961 enabled by default on 64-bit machines. Add --enable-big-digits option to

5112 this code path is really executed because I cannot move to such directory on

5148 gives improved memory leak detection when running under Valgrind, while taking
5149 advantage of pymalloc at other times.

6319 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6320 neither __int__ nor __long__, TypeError used to be raised (with a
6321 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6322 struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006519- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6520 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6521 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6522 ``printf`` function, whereas PyString_FromFormat has an independent
6523 implementation and uses "%zd" on all platforms for size_t values.
6524 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006540- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006541 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006542 was correctly parsed but parsing of subsequent arguments failed.
6543
Vinay Sajip35e3b032008-09-01 14:33:59 +00006544- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006545 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6546 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6547 when given a tuple of classes as second argument, were looking up
6548 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6549 type object.
6550
Neal Norwitz18aa3882008-08-24 05:04:52 +00006551- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006620 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6621 for catch_warnings() also led to an improvement in the raising of a
6622 DeprecationWarning related to warnings.warn_explicit().
6623

6649 without limit.
6650
Benjamin Peterson37346b22008-08-23 20:27:43 +00006651- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006688What's New in Python 2.6 beta 3?
6689================================
6690
Barry Warsaw07a4a382008-08-21 01:15:08 +00006691*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006692
6693Core and Builtins
6694-----------------
6695
Guido van Rossumf8402962008-08-20 15:01:50 +00006696- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6697 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6698 extensions do not automatically benefit from the class attribute
6699 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6700 to their tp_flags field if they care. This is a backwards
6701 compatibility feature; in 3.0, all types will use the cache by
6702 default.
6703
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006704- Keyword arguments can now follow starred arguments. (``f(a, *args,
6705 keyword=23)`` is now valid syntax.)
6706
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006707- ctypes function pointers that are COM methods have a boolean True
6708 value again.
6709
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006710- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6711 by denying s# to parse objects that have a releasebuffer procedure,
6712 and introducing s*.
6713
Georg Brandl1e13ea92008-08-11 09:07:59 +00006714- Issue #3537: Fix an assertion failure when an empty but presized dict
6715 object was stored in the freelist.
6716
Mark Dickinsonb6467572008-08-04 21:30:09 +00006717- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6718 ValueError consistently across platforms.
6719
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006720- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6721 (64bit Unix, for example), unichr() would truncate its argument and return
6722 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6723
Neal Norwitze7d8be82008-07-31 17:17:14 +00006724- Apply security patches from Apple.
6725
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006726- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6727 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6728
Antoine Pitrou92f82162008-07-25 22:22:08 +00006729- Issue #1819: function calls with several named parameters are now on
6730 average 35% faster (as measured by pybench).
6731
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006732- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6733 the python debugger steps into a class statement: the free variables (local
6734 variables defined in an outer scope) would be deleted from the outer scope.
6735
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006736- Issue #2620: Overflow checking when allocating or reallocating memory
6737 was not always being done properly in some python types and extension
6738 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6739 all been updated to perform better checks and places in the code that
6740 would previously leak memory on the error path when such an allocation
6741 failed have been fixed.

6744-------
6745
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006746- Issue #3612: Added some missing basic types in ctypes.wintypes.
6747
Benjamin Petersone977ad42008-08-20 01:42:01 +00006748- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6749 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6750
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006751- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6752 version reported by these tools does not necessarily follow the python
6753 version numbering scheme, so the module is less strict when parsing it.
6754
Nick Coghlanf70385a2008-08-18 12:42:46 +00006755- Issue #2235: Added Py3k warnings for types which will become unhashable
6756 under the stricter __hash__ inheritance rules in 3.0. Several types
6757 which did not meet the rules for hash invariants and were already
6758 unhashable in 3.0 have now been explicitly flagged as unhashable in
6759 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6760 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6761
Brett Cannon88f801d2008-08-18 00:46:22 +00006762- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6763 imported into the module but exposed as part of the module's API.
6764
Brett Cannon7b96f072008-08-18 00:41:11 +00006765- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6766
Brett Cannon46225e72008-08-18 00:36:52 +00006767- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006769- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6770
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006771- Issue #3575: Incremental decoder's decode function now takes bytearray
6772 by using 's*' instead of 't#'.
6773
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006774- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006775 fails unicode conversion on 2nd parameter. (windows only)
6776
Georg Brandl222e2082010-08-01 22:27:39 +00006777- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006778 in a redirect.
6779
Brett Cannonabe423e2008-08-16 21:47:07 +00006780- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006781 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006782
Facundo Batistaeb90b782008-08-16 14:44:07 +00006783- Issue #2776: fixed small issue when handling an URL with double slash
6784 after a 302 response in the case of not going through a proxy.
6785
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006786- Issue #2676: in the email package, content-type parsing was hanging on
6787 pathological input because of quadratic or exponential behaviour of a
6788 regular expression.
6789
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006790- Issue #3476: binary buffered reading through the new "io" library is now
6791 thread-safe.
6792
Brett Cannonbf3157b2008-08-14 05:00:03 +00006793- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6794 since mimetools itself is deprecated. Because modules are cached, all
6795 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6796
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006797- Issue #3134: shutil referenced undefined WindowsError symbol.
6798
Robert Schuppenies14646332008-08-10 11:01:53 +00006799- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6800 menu entries were not deleted.
6801
Brett Cannon83e81842008-08-09 23:30:55 +00006802- Copied the implementation of reduce() to _functools.reduce() to have a
6803 version that did not raise a DeprecationWarning under -3.
6804
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006805- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6806 a MemoryError rather than silently stop the iteration.
6807
Guido van Rossum59ce9012008-08-09 14:55:34 +00006808- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6809 to _sre.compile() will now be rejected. This should not affect anybody
6810 since the re.compile() function never generates invalid re-bytecode.
6811
Skip Montanaroa032bf42008-08-08 22:52:51 +00006812- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6813 upon first access it can be automatically initialized from the csv file if
6814 it wasn't initialized during instantiation.
6815
Brett Cannon3aa2a492008-08-06 22:28:09 +00006816- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6817 the reload() built-in has been removed.
6818
Brett Cannon7e30b672008-08-04 21:52:25 +00006819- Changed code in the following modules/packages to remove warnings raised

6888-----------------
6889
Georg Brandl3e483f62008-07-16 22:57:41 +00006890- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6891 its methods now allow for items objects that can be converted to
6892 an integer using operator.index().
6893
Mark Dickinson64b7e502008-07-16 09:40:03 +00006894- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6895 produced a ValueError instead of giving the correct float.
6896
Eric Smitha5fa5a22008-07-16 00:11:49 +00006897- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6898 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6899
Mark Dickinson7103aa42008-07-15 19:08:33 +00006900- Issue #3008: the float type has a new instance method 'float.hex'
6901 and a new class method 'float.fromhex' to convert floating-point
6902 numbers to and from hexadecimal strings, respectively.
6903
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006904- Issue #2235: __hash__ is once again inherited by default. To allow
6905 collections.Hashable to remain meaningful in the presence of the
6906 default hash implementation (object.__hash__), it is now possible
6907 to explicit block inheritance of hash by setting __hash__=None at
6908 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6909 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00006911- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6912 the parent module cannot be found while performing an absolute import.
6913 This means that an incorrectly defined __package__ attribute will
6914 now only prevent relative imports in that module rather than causing
6915 all imports from that module to fail.
6916
Nick Coghlan14ff9942008-07-08 14:21:42 +00006917- Issue #2517: Allow unicode messages in Exceptions again by correctly

6927 another thread's dictionary.
6928
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006929- Issue #3004: Minor change to slice.indices(): the start and stop
6930 arguments are now treated identically, making the behaviour easier
6931 to describe and understand. For example, slice(None, -10,
6932 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6933 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6934 10, -1).

6977 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006978 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006979 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006995- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007386 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007387
7388 This is controlled by the configure argument ``--with-universal-archs``:
7389
7390 - ``--with-universal-archs=all``: install 4-way universal
7391
7392 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7393
7394 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7395
7396 This option should be used in combination with ``--enable-universalsdk=``.
7397
7398 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7402
Georg Brandl74a1dea2008-05-28 11:21:39 +00007403- Add ``PyType_Modified()`` as a public API to clear the type cache.
7404
7405- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007406
7407- The PyString functions have been renamed to PyBytes. A batch of
7408 defines were added so that the linker still sees the original
7409 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007447- Issue #1631171: Re-implement the 'warnings' module in C (the
7448 original Python code has been kept as backup). This will allow for
7449 using the 'warning's machinery in such places as the parser where
7450 use of pure Python code is not possible. Both the ``showarning()``
7451 and ``formatwarning()`` gain an optional 'line' argument which is
7452 not called by default for backwards-compatibility reasons. Setting
7453 ``warnings.showwarning()`` to an implementation that lacks support
7454 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007479- The getpass module has been improved on Unix. It now uses /dev/tty
7480 by default and uses stderr instead of stdout. A GetPassWarning is
7481 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007496- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007497 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Issue #2550: The approach used by client/server code for obtaining
7518 ports to listen on in network-oriented tests has been refined in an
7519 effort to facilitate running multiple instances of the entire
7520 regression test suite in parallel without issue.
7521 test_support.bind_port() has been fixed such that it will always
7522 return a unique port -- which wasn't always the case with the
7523 previous implementation, especially if socket options had been set
7524 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7525 new implementation of bind_port() will actually raise an exception
7526 if it is passed an AF_INET/SOCK_STREAM socket with either the
7527 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7528 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7529 the socket it's been passed. This currently only applies to
7530 Windows. This option prevents any other sockets from binding to the
7531 host/port we've bound to, thus removing the possibility of the
7532 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7533 when a second SOCK_STREAM socket binds and accepts to a host/port
7534 that's already been bound by another socket. The optional preferred
7535 port parameter to bind_port() has been removed. Under no
7536 circumstances should tests be hard coding ports!
7537
7538 test_support.find_unused_port() has also been introduced, which will
7539 pass a temporary socket object to bind_port() in order to obtain an
7540 unused port. The temporary socket object is then closed and
7541 deleted, and the port is returned. This method should only be used
7542 for obtaining an unused port in order to pass to an external program
7543 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7544 a parameter to a server-oriented class that doesn't give you direct
7545 access to the underlying socket used.
7546
7547 Finally, test_support.HOST has been introduced, which should be used
7548 for the host argument of any relevant socket calls (i.e. bind and
7549 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007550
7551 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007552 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007553 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7554 test_asynchat and test_socket_ssl.
7555
Georg Brandl3ee81df2008-05-17 18:14:43 +00007556 It is now possible for multiple instances of the regression test
7557 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007836- Added the future_builtins module, which contains hex() and oct().
7837 These are the PEP 3127 version of these functions, designed to be
7838 compatible with the hex() and oct() builtins from Python 3.0. They
7839 differ slightly in their output formats from the existing, unchanged
7840 Python 2.6 builtins. The expected usage of the future_builtins
7841 module is:
7842 from future_builtins import hex, oct
7843
Eric Smith7ef40bf2008-02-20 23:34:22 +00007844- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7845 exponents for exponents with absolute value < 100. Follows C99
7846 standard. This is a change on Windows, which would use 3 digits.
7847 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7848 so that any alterations it does to the resulting string will be
7849 available in stringlib/formatter.h (for float.__format__).
7850
Eric Smith5a3c1352008-02-19 13:21:56 +00007851- Implemented PEP 3101, Advanced String Formatting. This adds a new
7852 builtin format(); a format() method for str and unicode; a
7853 __format__() method to object, str, unicode, int, long, float, and
7854 datetime; the class string.Formatter; and the C API
7855 PyObject_Format().
7856
Georg Brandl3ee81df2008-05-17 18:14:43 +00007857- Fixed several potential crashes, all caused by specially crafted
7858 __del__ methods exploiting objects in temporarily inconsistent
7859 state.

7870 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007871
Georg Brandl3ee81df2008-05-17 18:14:43 +00007872- Issue #2045: Fix an infinite recursion triggered when printing a
7873 subclass of collections.defaultdict, if its default_factory is set
7874 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007875

7885
Georg Brandl3ee81df2008-05-17 18:14:43 +00007886- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7887 calls. Python expected the return type int but the fork familie
7888 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007902- Patch #1473257: generator objects gain a gi_code attribute. This is
7903 the same object as the func_code attribute of the function that
7904 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007905
Georg Brandl3ee81df2008-05-17 18:14:43 +00007906- Issue #1920: "while 0" statements were completely removed by the
7907 compiler, even in the presence of an "else" clause, which is
7908 supposed to be run when the condition is false. Now the compiler
7909 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007910
Guido van Rossumeead05f2008-01-24 18:21:02 +00007911- A few crashers fixed: weakref_in_del.py (issue #1377858);
7912 loosing_dict_ref.py (issue #1303614, test67.py);
7913 borrowed_ref_[34].py (not in tracker).
7914
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007915- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007916 suppressed while an extension is loaded by calling SetErrorMode in
7917 dynload_win.c. The error is still reported properly.
7918
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007920 several extension methods and modules do not work without unicode
7921 support.
7922
Georg Brandl26543b12008-01-21 18:36:51 +00007923- Issue #1882: when compiling code from a string, encoding cookies in the
7924 second line of code were not always recognized correctly.
7925
Georg Brandl14404b62008-01-19 19:27:05 +00007926- Issue #1679: "0x" was taken as a valid integer literal.
7927
Georg Brandl6caad7d2008-01-26 14:19:22 +00007928- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007929 added.
7930
Christian Heimesc94e2b52008-01-14 04:13:37 +00007931- sys.float_info / PyFloat_GetInfo: The floating point information
7932 object was converted from a dict to a specialized structseq object.
7933
Georg Brandl3ee81df2008-05-17 18:14:43 +00007934- Patch #1816: Added sys.flags structseq. It exposes the status of
7935 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007936
Georg Brandl3ee81df2008-05-17 18:14:43 +00007937- Objects/structseq.c: Implemented new structseq representation. The
7938 patch makes structseqs (e.g. the return value of os.stat) more
7939 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007940
Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Patch #1700288: added a type attribute cache that caches method
7942 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007943
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007944- Bug #1776: __import__() no longer accepts filenames on any platform.
7945 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007946
Georg Brandlaed6c662008-01-07 17:25:53 +00007947- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7948
Georg Brandl3ee81df2008-05-17 18:14:43 +00007949- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7950 envvar and sys.dont_write_bytecode attribute. All these can be set
7951 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007952
Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Improve some exception messages when Windows fails to load an
7954 extension module. Now we get for example '%1 is not a valid Win32
7955 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007956
Georg Brandl3ee81df2008-05-17 18:14:43 +00007957- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007959- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7960 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007961
Christian Heimes0a8143f2007-12-18 23:22:54 +00007962- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963 and INF. float("nan"), float("inf") and float("-inf") now work on
7964 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007965
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Compiler now generates simpler and faster code for dictionary
7967 literals. The oparg for BUILD_MAP now indicates an estimated
7968 dictionary size. There is a new opcode, STORE_MAP, for adding
7969 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007970
Georg Brandl3ee81df2008-05-17 18:14:43 +00007971- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007976- Issue #1538: Avoid copying string in split/rsplit if the split char
7977 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007978
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007979- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007980 SystemError.
7981
Nick Coghlanef01d822007-12-03 12:55:17 +00007982- PEP 366: Allow explicit relative imports when executing modules
7983 inside packages with the -m switch via a new module level
7984 __package__ attribute.
7985
Georg Brandl3ee81df2008-05-17 18:14:43 +00007986- Issue #1402: Fix a crash on exit, when another thread is still
7987 running, and if the deallocation of its frames somehow calls the
7988 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007989

7994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Issue #1460: The utf-7 incremental decoder did not accept truncated
7996 input. It now correctly saves its state between chunks of data.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Patch #1739468: Directories and zipfiles containing a __main__.py
7999 file can now be directly executed by passing their name to the
8000 interpreter. The directory/zipfile is automatically inserted as the
8001 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008002
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003- Issue #1265: Fix a problem with sys.settrace, if the tracing
8004 function uses a generator expression when at the same time the
8005 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008006
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008007- sets and frozensets now have an isdisjoint() method.
8008
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008009- optimize the performance of builtin.sum().
8010
Neal Norwitz44f326e2007-10-05 05:29:17 +00008011- Fix warnings found by the new version of the Coverity checker.
8012
Georg Brandl21e99f42010-03-07 15:23:59 +00008013- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8015 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008016
Georg Brandl3ee81df2008-05-17 18:14:43 +00008017- Issue #1686386: Tuple's tp_repr did not take into account the
8018 possibility of having a self-referential tuple, which is possible
8019 from C code. Nor did object's tp_str consider that a type's tp_str
8020 could do something that could lead to an inifinite recursion.
8021 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8022 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008023
Georg Brandl3ee81df2008-05-17 18:14:43 +00008024- Issue #1164: It was possible to trigger deadlock when using the
8025 'print' statement to write to a file since the GIL was not released
8026 as needed. Now PyObject_Print() does the right thing along with
8027 various tp_print implementations of the built-in types and those in
8028 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008029
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Issue #1147: Exceptions were directly allowing string exceptions in
8031 their throw() method even though string exceptions no longer
8032 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008033
Georg Brandl3ee81df2008-05-17 18:14:43 +00008034- Issue #1096: Prevent a segfault from getting the repr of a very
8035 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008036
Brett Cannon1e534b52007-09-07 04:18:30 +00008037- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008038 PyObject_Call() never calling back out to Python code to trigger
8039 recursion depth updates/checks. Required the creation of a static
8040 RuntimeError instance in case normalizing an exception put the
8041 recursion check value past its limit. Fixes crashers
8042 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Patch #1031213: Decode source line in SyntaxErrors back to its

8048 with %G.
8049
Georg Brandl3ee81df2008-05-17 18:14:43 +00008050- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00008057- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058 __*__ attributes. (Some already existed, e.g., __doc__ and
8059 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008060
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008061- Add -3 option to the interpreter to warn about features that are
8062 deprecated and will be changed/removed in Python 3.0.
8063
Georg Brandl2134e752007-05-21 20:34:16 +00008064- Patch #1686487: you can now pass any mapping after '**' in function
8065 calls.
8066
Collin Winter62903052007-05-18 23:11:24 +00008067- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008068 "except E as target:". This is to provide forwards compatibility
8069 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008070
Brett Cannon229cee22007-05-05 01:34:02 +00008071- Deprecate BaseException.message as per PEP 352.
8072
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008074 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008075
Vinay Sajip8549ce32007-05-06 17:53:37 +00008076- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008077 setting a plain string, ie don't expand to single letter identifiers.
8078
Raymond Hettinger13936692007-04-11 18:40:58 +00008079- Request #1191699: Slices can now be pickled.
8080
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008081- Request #1193128: str.translate() now allows a None argument for
8082 translations that only remove characters without re-mapping the
8083 remaining characters.
8084
Georg Brandl5cb76c12007-03-21 09:00:39 +00008085- Patch #1682205: a TypeError while unpacking an iterable is no longer
8086 masked by a generic one with the message "unpack non-sequence".
8087
Neal Norwitzaa754b72007-03-21 06:39:48 +00008088- Remove unused file Python/fmod.c.
8089
Guido van Rossum143b5642007-03-23 04:58:42 +00008090- Bug #1683368: The object.__init__() and object.__new__() methods are
8091 now stricter in rejecting excess arguments. The only time when
8092 either allows excess arguments is when it is not overridden and the
8093 other one is. For backwards compatibility, when both are
8094 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008095 warning later). Also, type.__init__() insists on the same signature
8096 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008097
Georg Brandl3ee81df2008-05-17 18:14:43 +00008098- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8099 object to complex using its __complex__() method before falling back
8100 to the __float__() method. Therefore, the functions in the cmath
8101 module now can operate on objects that define a __complex__()
8102 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104- Patch #1623563: allow __class__ assignment for classes with
8105 __slots__. The old and the new class are still required to have the
8106 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008107
Georg Brandl3ee81df2008-05-17 18:14:43 +00008108- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00008111- Patch #1462488: Python no longer segfaults when
8112 ``object.__reduce_ex__()`` is called with an object that is faking
8113 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008114
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008118- Patch #1444529: the builtin compile() now accepts keyword arguments.
8119
Georg Brandl7b9c5552007-03-12 14:30:05 +00008120- Bug #1678647: write a newline after printing an exception in any
8121 case, even when converting the value to a string failed.
8122
Georg Brandl871f1bc2007-03-12 13:17:36 +00008123- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008124 its argument, if it exists. If not, it will work like before. This
8125 allows customizing the output of dir() in the presence of a
8126 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008128- Patch #922167: Python no longer segfaults when faced with infinitely
8129 self-recursive reload() calls (as reported by bug #742342).
8130
Georg Brandl3ee81df2008-05-17 18:14:43 +00008131- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008134- Patch #1491866: change the complex() constructor to allow
8135 parthensized forms. This means complex(repr(x)) now works instead of
8136 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008137
Georg Brandlaa2321b2007-03-07 00:40:28 +00008138- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139 makes the filenames the warning module prints much more sensible

8647
Facundo Batistad918a652007-04-24 13:54:38 +00008648- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008649 the client's request was successfully received, understood, and
8650 accepted. Now in these cases no error is raised in urllib (issue
8651 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008652

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008659- Added a timeout parameter to the constructor of other protocols
8660 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8661 work started with create_connection() and timeout in httplib, and
8662 closes patch #723312.
8663
Vinay Sajip8549ce32007-05-06 17:53:37 +00008664- Patch #1676823: Added create_connection() to socket.py, which may be
8665 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008666 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008667
Martin v. Löwis0af33882007-03-23 13:27:15 +00008668- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8688
Georg Brandlf66b6032007-03-14 08:27:52 +00008689- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008690 AttributeError instead of an IOError when the server's response
8691 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008692
Georg Brandl3ee81df2008-05-17 18:14:43 +00008693- Patch #957650: "%var%" environment variable references are now
8694 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008696
Georg Brandl3ee81df2008-05-17 18:14:43 +00008697- Patch #1429539: pdb now correctly initializes the __main__ module
8698 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008699 correctly now.
8700
Georg Brandlbad6f192007-03-13 21:32:56 +00008701- The nonobvious commands.getstatus() function is now deprecated.

8707
Georg Brandl3ee81df2008-05-17 18:14:43 +00008708- Patch #1530482: add pydoc.render_doc() which returns the
8709 documentation for a thing instead of paging it to stdout, which
8710 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008711
Georg Brandl3ee81df2008-05-17 18:14:43 +00008712- Patch #1533909: the timeit module now accepts callables in addition

8718 parameter which can be set to False to prevent the default
8719 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008720
Georg Brandl9e6b4702007-03-13 18:15:41 +00008721- Patch #1581073: add a flag to textwrap that prevents the dropping of
8722 whitespace while wrapping.
8723
Georg Brandl92a6bae2007-03-13 17:43:32 +00008724- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008725 are set for invalid interpolation sequences that would lead to
8726 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008727

8740
Georg Brandl94fe3f52007-03-13 09:32:11 +00008741- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008742 field names in its exception message if you try to write a record
8743 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008761

8769 returned string up to the first NUL character.
8770

8780
Georg Brandl3ee81df2008-05-17 18:14:43 +00008781- unittest now verifies more of its assumptions. In particular,
8782 TestCase and TestSuite subclasses (not instances) are no longer
8783 accepted in TestSuite.addTest(). This should cause no
8784 incompatibility since it never made sense with ordinary subclasses
8785 -- the failure just occurred later, with a more cumbersome
8786 exception.

8795 given a unicode argument and os.listdir() returns unicode filenames.
8796
Georg Brandl3ee81df2008-05-17 18:14:43 +00008797- Patch #1673619: setup.py identifies extension modules it doesn't
8798 know how to build and those it knows how to build but that fail to
8799 build.

9151 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9152 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009168- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169 time so that opening a database previously created with the DB_DUP
9170 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9171 opens. Specifically: dictionary assignment to a DB object will
9172 replace all values for a given key when the database allows
9173 duplicate values. DB users should use DB.put(k, v) when they want
9174 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009175

9181 characters with ASCII value less than 32. Also, it correctly quotes
9182 dots only if they occur on a single line, as opposed to the previous
9183 behavior of quoting dots if they are the second character of any
9184 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009185
