1306 In particular, fix extension module build failures when trying to use
1307 32-bit-only installer Pythons on systems with Xcode 4 (currently
1308 OS X 10.8, 10.7, and optionally 10.6).
1309 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1310 * Since Xcode 4 removes ppc support, extension module builds now
1311 check for ppc compiler support and by default remove ppc and
1312 ppc64 archs when they are not available.
1313 * Extension module builds now revert to using system installed
1314 headers and libs (/usr and /System/Library) if the SDK used
1315 to build the interpreter is not installed or has moved.
1316 * Try to avoid building extension modules with deprecated
1317 and problematic Apple llvm-gcc compiler. If original compiler
1318 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01001749- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1750 Distutils-based packages with C extension modules may fail because
1751 Apple has removed gcc-4.2, the version used to build python.org
1752 64-bit/32-bit Pythons. If the user does not explicitly override
1753 the default C compiler by setting the CC environment variable,
1754 Distutils will now attempt to compile extension modules with clang
1755 if gcc-4.2 is required but not found. Also as a convenience, if
1756 the user does explicitly set CC, substitute its value as the default
1757 compiler in the Distutils LDSHARED configuration variable for OS X.
1758 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1759 SDK, neither of which are available in Xcode 4. This change does not
1760 attempt to override settings to support their use with Xcode 4.)

2011 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2012 interpreter process. This could cause failures in non-Distutils subprocesses
2013 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002014 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002015 deployment target only in the environment of each build subprocess. It is
2016 still possible to globally override the default by setting

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003496- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3497 start byte and the continuation byte(s) are now considered invalid, instead
3498 of the number of bytes specified by the start byte.
3499 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3500 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3501 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3502 Previous versions returned a single u'\ufffd'.
3503
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003504- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003505 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3506 arises from the "Overriding __eq__ blocks inheritance ..." warning
3507 when turned into an exception: in this case the exception simply
3508 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003509
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003510- Issue #8748: Fix two issues with comparisons between complex and integer
3511 objects. (1) The comparison could incorrectly return True in some cases
3512 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3513 (2) The comparison raised an OverflowError for large integers, leading
3514 to unpredictable exceptions when combining integers and complex objects
3515 in sets or dicts.
3516
Mark Dickinson81336372010-05-30 12:12:25 +00003517- Issue #5211: Implicit coercion for the complex type is now completely
3518 removed. (Coercion for arithmetic operations was already removed in 2.7
3519 alpha 4, but coercion for rich comparisons was accidentally left in.)
3520
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003521- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3522 and error handler, instead of writing to the C stderr file in utf-8
3523
Georg Brandlfee0f442010-05-22 21:26:21 +00003524- Issue #7902: When using explicit relative import syntax, don't try implicit
3525 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00003526
Georg Brandlfee0f442010-05-22 21:26:21 +00003527- Issue #7079: Fix a possible crash when closing a file object while using it
3528 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00003530- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00003531 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00003536- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
3537 of the interpreter to set sys.argv without also modifying sys.path. This
3538 helps fix `CVE-2008-5983

Georg Brandlfee0f442010-05-22 21:26:21 +00003897- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3898 with a non-empty format string. This is an effort to future-proof user
3899 code. If a derived class does not currently implement __format__ but later
3900 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003901 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003902 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003952- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3953 InvalidOperation instead of returning False. (Comparisons involving a quiet
3954 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3955 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003957- Issue #2531: Comparison operations between floats and Decimal instances now
3958 return a result based on the numeric values of the operands; previously they

3976 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00004334- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4335 and add the additional members returned in an OSVERSIONINFOEX structure. The
4336 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004339- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4340 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4341 returning NULL. The macro now returns a statically allocated empty string
4342 instead.

4352 strings,
4353 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4354 numeric strings corresponding to subnormal values,
4355 (3) a memory leak for some values large enough to cause overflow, and
4356 (4) a number of flaws that could lead to incorrectly rounded results.

4375
Georg Brandlba83f822010-03-14 09:50:54 +00004376- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00004387- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004388 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004389 Also, raise ValueError rather than TypeError when an unknown TIPC address
4390 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004394- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004395 file position when calling `truncate()`. It would previously change the file
4396 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004397 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4398
Georg Brandlba83f822010-03-14 09:50:54 +00004399- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4400 class used to represent files stored inside an archive. The new
4401 implementation is significantly faster and can be wrapped in a
4402 ``io.BufferedReader`` object for more speedups. It also solves an issue
4403 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4404 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004414- Issue #7748: Since unicode values are supported for some metadata options in
4415 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4416 encoded string for them. This ensures that the upload and register commands
4417 send the correct values to PyPI without any error.

4502 These functions and methods now raise TypeError instead. The majority of the
4503 effects of this change are in the extension modules, but some core functions
4504 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4505 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004688- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4689 decimal string that's guaranteed to round back to x under correct rounding
4690 (with round-half-to-even rounding mode). Previously it gave a string based on
4691 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4692 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4693 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004695- Issue #7117: On almost all platforms: float-to-string and string-to-float
4696 conversions within Python are now correctly rounded. Places these conversions
4697 occur include: str for floats and complex numbers; the float and complex
4698 constructors; old-style and new-style numeric formatting; serialization and
4699 deserialization of floats and complex numbers using marshal, pickle and json;
4700 parsing of float and imaginary literals in Python code; Decimal-to-float
4701 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004702
Georg Brandlba83f822010-03-14 09:50:54 +00004703 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4704 providing correctly-rounded strtod and dtoa C functions. This code is
4705 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4706 the C compiler. There may be a small number of platforms on which correct
4707 operation of this code cannot be guaranteed, so the code is not used: notably,
4708 this applies to platforms where the C double format is not IEEE 754 binary64,
4709 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4710 and Python's configure script is unable to determine how to change the FPU
4711 precision. On these platforms conversions use the platform strtod and dtoa,
4712 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004714- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4715 uses the correctly-rounded string <-> float conversions described above (when
4716 available), and so produces correctly rounded results that will display nicely
4717 under the float repr. There are two related small changes: (1) round now
4718 accepts any class with an ``__index__()`` method for its second argument (but
4719 no longer accepts floats for the second argument), and (2) an excessively
4720 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4721 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004939 untrackable objects are not tracked by the garbage collector. This can reduce
4940 the size of collections and therefore the garbage collection overhead on
4941 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00005014- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5015 existing .py counterpart, override the co_filename attributes of all code

5071
Georg Brandlba83f822010-03-14 09:50:54 +00005072- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5073 file objects with closefd=False. The file descriptor is still kept open but
5074 the file object behaves like a closed file. The ``FileIO`` object also got a
5075 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005098- On windows, ``os.chdir()`` given unicode was not working if

5100 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00005126- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5127 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5128 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00005131- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006507- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6509 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6510 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00006608 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6609 for catch_warnings() also led to an improvement in the raising of a
6610 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006676What's New in Python 2.6 beta 3?
6677================================
6678
Barry Warsaw07a4a382008-08-21 01:15:08 +00006679*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006680
6681Core and Builtins
6682-----------------
6683
Guido van Rossumf8402962008-08-20 15:01:50 +00006684- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6685 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6686 extensions do not automatically benefit from the class attribute
6687 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6688 to their tp_flags field if they care. This is a backwards
6689 compatibility feature; in 3.0, all types will use the cache by
6690 default.
6691
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006692- Keyword arguments can now follow starred arguments. (``f(a, *args,
6693 keyword=23)`` is now valid syntax.)
6694
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006695- ctypes function pointers that are COM methods have a boolean True
6696 value again.
6697
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006698- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6699 by denying s# to parse objects that have a releasebuffer procedure,
6700 and introducing s*.
6701
Georg Brandl1e13ea92008-08-11 09:07:59 +00006702- Issue #3537: Fix an assertion failure when an empty but presized dict
6703 object was stored in the freelist.
6704
Mark Dickinsonb6467572008-08-04 21:30:09 +00006705- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6706 ValueError consistently across platforms.
6707
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006708- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6709 (64bit Unix, for example), unichr() would truncate its argument and return
6710 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6711
Neal Norwitze7d8be82008-07-31 17:17:14 +00006712- Apply security patches from Apple.
6713
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006714- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6715 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6716
Antoine Pitrou92f82162008-07-25 22:22:08 +00006717- Issue #1819: function calls with several named parameters are now on
6718 average 35% faster (as measured by pybench).
6719
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006720- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6721 the python debugger steps into a class statement: the free variables (local
6722 variables defined in an outer scope) would be deleted from the outer scope.
6723
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006724- Issue #2620: Overflow checking when allocating or reallocating memory
6725 was not always being done properly in some python types and extension
6726 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6727 all been updated to perform better checks and places in the code that
6728 would previously leak memory on the error path when such an allocation
6729 failed have been fixed.

6732-------
6733
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006734- Issue #3612: Added some missing basic types in ctypes.wintypes.
6735
Benjamin Petersone977ad42008-08-20 01:42:01 +00006736- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6737 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6738
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006739- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6740 version reported by these tools does not necessarily follow the python
6741 version numbering scheme, so the module is less strict when parsing it.
6742
Nick Coghlanf70385a2008-08-18 12:42:46 +00006743- Issue #2235: Added Py3k warnings for types which will become unhashable
6744 under the stricter __hash__ inheritance rules in 3.0. Several types
6745 which did not meet the rules for hash invariants and were already
6746 unhashable in 3.0 have now been explicitly flagged as unhashable in
6747 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6748 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6749
Brett Cannon88f801d2008-08-18 00:46:22 +00006750- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6751 imported into the module but exposed as part of the module's API.
6752
Brett Cannon7b96f072008-08-18 00:41:11 +00006753- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6754
Brett Cannon46225e72008-08-18 00:36:52 +00006755- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006757- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6758
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006759- Issue #3575: Incremental decoder's decode function now takes bytearray
6760 by using 's*' instead of 't#'.
6761
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006762- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006763 fails unicode conversion on 2nd parameter. (windows only)
6764
Georg Brandl222e2082010-08-01 22:27:39 +00006765- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006766 in a redirect.
6767
Brett Cannonabe423e2008-08-16 21:47:07 +00006768- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006769 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006770
Facundo Batistaeb90b782008-08-16 14:44:07 +00006771- Issue #2776: fixed small issue when handling an URL with double slash
6772 after a 302 response in the case of not going through a proxy.
6773
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006774- Issue #2676: in the email package, content-type parsing was hanging on
6775 pathological input because of quadratic or exponential behaviour of a
6776 regular expression.
6777
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006778- Issue #3476: binary buffered reading through the new "io" library is now
6779 thread-safe.
6780
Brett Cannonbf3157b2008-08-14 05:00:03 +00006781- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6782 since mimetools itself is deprecated. Because modules are cached, all
6783 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6784
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006785- Issue #3134: shutil referenced undefined WindowsError symbol.
6786
Robert Schuppenies14646332008-08-10 11:01:53 +00006787- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6788 menu entries were not deleted.
6789
Brett Cannon83e81842008-08-09 23:30:55 +00006790- Copied the implementation of reduce() to _functools.reduce() to have a
6791 version that did not raise a DeprecationWarning under -3.
6792
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006793- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6794 a MemoryError rather than silently stop the iteration.
6795
Guido van Rossum59ce9012008-08-09 14:55:34 +00006796- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6797 to _sre.compile() will now be rejected. This should not affect anybody
6798 since the re.compile() function never generates invalid re-bytecode.
6799
Skip Montanaroa032bf42008-08-08 22:52:51 +00006800- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6801 upon first access it can be automatically initialized from the csv file if
6802 it wasn't initialized during instantiation.
6803
Brett Cannon3aa2a492008-08-06 22:28:09 +00006804- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6805 the reload() built-in has been removed.
6806
Brett Cannon7e30b672008-08-04 21:52:25 +00006807- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006808 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6812 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6813 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006814

Antoine Pitroude781a42008-08-09 12:43:23 +00006819 asking for a specific length. This problem only affected files opened

6876-----------------
6877
Georg Brandl3e483f62008-07-16 22:57:41 +00006878- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6879 its methods now allow for items objects that can be converted to
6880 an integer using operator.index().
6881
Mark Dickinson64b7e502008-07-16 09:40:03 +00006882- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6883 produced a ValueError instead of giving the correct float.
6884
Eric Smitha5fa5a22008-07-16 00:11:49 +00006885- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6886 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6887
Mark Dickinson7103aa42008-07-15 19:08:33 +00006888- Issue #3008: the float type has a new instance method 'float.hex'
6889 and a new class method 'float.fromhex' to convert floating-point
6890 numbers to and from hexadecimal strings, respectively.
6891
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006892- Issue #2235: __hash__ is once again inherited by default. To allow
6893 collections.Hashable to remain meaningful in the presence of the
6894 default hash implementation (object.__hash__), it is now possible
6895 to explicit block inheritance of hash by setting __hash__=None at
6896 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6897 level.
6898
Nick Coghlanb028f502008-07-13 14:52:36 +00006899- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6900 the parent module cannot be found while performing an absolute import.
6901 This means that an incorrectly defined __package__ attribute will
6902 now only prevent relative imports in that module rather than causing
6903 all imports from that module to fail.
6904
Nick Coghlan14ff9942008-07-08 14:21:42 +00006905- Issue #2517: Allow unicode messages in Exceptions again by correctly

6915 another thread's dictionary.
6916
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006917- Issue #3004: Minor change to slice.indices(): the start and stop
6918 arguments are now treated identically, making the behaviour easier
6919 to describe and understand. For example, slice(None, -10,
6920 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6921 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6922 10, -1).
6923
Georg Brandl278fc502008-07-19 12:46:12 +00006924- Issue #3219: Calling a function with repeated keyword arguments,
6925 f(a=2, a=23), would not cause a syntax error. This was a regression
6926 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006927
Georg Brandl278fc502008-07-19 12:46:12 +00006928- Issue #2862: Make int and float freelist management consistent with
6929 other freelists. Changes their CompactFreeList apis into

6936 api functions without holding the GIL, which could lead to a fatal
6937 error when they failed.
6938
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006939- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006964- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6965 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006966 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006967 content-length. The problem had been corrected in the 2.4 branch, but never
6968 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006983- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6984 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Issue #1631171: Re-implement the 'warnings' module in C (the
7439 original Python code has been kept as backup). This will allow for
7440 using the 'warning's machinery in such places as the parser where
7441 use of pure Python code is not possible. Both the ``showarning()``
7442 and ``formatwarning()`` gain an optional 'line' argument which is
7443 not called by default for backwards-compatibility reasons. Setting
7444 ``warnings.showwarning()`` to an implementation that lacks support
7445 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007487- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007488 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007508- Issue #2550: The approach used by client/server code for obtaining
7509 ports to listen on in network-oriented tests has been refined in an
7510 effort to facilitate running multiple instances of the entire
7511 regression test suite in parallel without issue.
7512 test_support.bind_port() has been fixed such that it will always
7513 return a unique port -- which wasn't always the case with the
7514 previous implementation, especially if socket options had been set
7515 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7516 new implementation of bind_port() will actually raise an exception
7517 if it is passed an AF_INET/SOCK_STREAM socket with either the
7518 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7519 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7520 the socket it's been passed. This currently only applies to
7521 Windows. This option prevents any other sockets from binding to the
7522 host/port we've bound to, thus removing the possibility of the
7523 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7524 when a second SOCK_STREAM socket binds and accepts to a host/port
7525 that's already been bound by another socket. The optional preferred
7526 port parameter to bind_port() has been removed. Under no
7527 circumstances should tests be hard coding ports!
7528
7529 test_support.find_unused_port() has also been introduced, which will
7530 pass a temporary socket object to bind_port() in order to obtain an
7531 unused port. The temporary socket object is then closed and
7532 deleted, and the port is returned. This method should only be used
7533 for obtaining an unused port in order to pass to an external program
7534 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7535 a parameter to a server-oriented class that doesn't give you direct
7536 access to the underlying socket used.
7537
7538 Finally, test_support.HOST has been introduced, which should be used
7539 for the host argument of any relevant socket calls (i.e. bind and
7540 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007541
7542 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007543 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007544 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7545 test_asynchat and test_socket_ssl.
7546
Georg Brandl3ee81df2008-05-17 18:14:43 +00007547 It is now possible for multiple instances of the regression test
7548 suite to run in parallel without issue.

7816
Fred Drakea8ee94b2008-03-01 02:45:07 +00007817- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007818 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007819
Georg Brandlad61bc82008-02-23 15:11:18 +00007820- Issue #2067: file.__exit__() now calls subclasses' close() method.
7821

Facundo Batistafc2d0102008-02-23 12:01:13 +00007826
Eric Smitha73fbe72008-02-23 03:09:44 +00007827- Added the future_builtins module, which contains hex() and oct().
7828 These are the PEP 3127 version of these functions, designed to be
7829 compatible with the hex() and oct() builtins from Python 3.0. They
7830 differ slightly in their output formats from the existing, unchanged
7831 Python 2.6 builtins. The expected usage of the future_builtins
7832 module is:
7833 from future_builtins import hex, oct
7834
Eric Smith7ef40bf2008-02-20 23:34:22 +00007835- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7836 exponents for exponents with absolute value < 100. Follows C99
7837 standard. This is a change on Windows, which would use 3 digits.
7838 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7839 so that any alterations it does to the resulting string will be
7840 available in stringlib/formatter.h (for float.__format__).
7841
Eric Smith5a3c1352008-02-19 13:21:56 +00007842- Implemented PEP 3101, Advanced String Formatting. This adds a new
7843 builtin format(); a format() method for str and unicode; a
7844 __format__() method to object, str, unicode, int, long, float, and
7845 datetime; the class string.Formatter; and the C API
7846 PyObject_Format().
7847
Georg Brandl3ee81df2008-05-17 18:14:43 +00007848- Fixed several potential crashes, all caused by specially crafted
7849 __del__ methods exploiting objects in temporarily inconsistent
7850 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007851
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007852- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007853 prevent a possible crash: an Abstract Base Class would try to access
7854 a slot on a registered virtual subclass.

7861 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007862
Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Issue #2045: Fix an infinite recursion triggered when printing a
7864 subclass of collections.defaultdict, if its default_factory is set
7865 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007866
Christian Heimesf75dbef2008-02-08 00:11:31 +00007867- Fixed a minor memory leak in dictobject.c. The content of the free
7868 list was not freed on interpreter shutdown.
7869
Georg Brandl21e99f42010-03-07 15:23:59 +00007870- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007871 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007872

7876
Georg Brandl3ee81df2008-05-17 18:14:43 +00007877- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7878 calls. Python expected the return type int but the fork familie
7879 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007880

Georg Brandl3ee81df2008-05-17 18:14:43 +00007893- Patch #1473257: generator objects gain a gi_code attribute. This is
7894 the same object as the func_code attribute of the function that
7895 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007896
Georg Brandl3ee81df2008-05-17 18:14:43 +00007897- Issue #1920: "while 0" statements were completely removed by the
7898 compiler, even in the presence of an "else" clause, which is
7899 supposed to be run when the condition is false. Now the compiler
7900 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007901
Guido van Rossumeead05f2008-01-24 18:21:02 +00007902- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007906- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007907 suppressed while an extension is loaded by calling SetErrorMode in
7908 dynload_win.c. The error is still reported properly.
7909
Georg Brandl3ee81df2008-05-17 18:14:43 +00007910- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007911 several extension methods and modules do not work without unicode
7912 support.
7913
Georg Brandl26543b12008-01-21 18:36:51 +00007914- Issue #1882: when compiling code from a string, encoding cookies in the
7915 second line of code were not always recognized correctly.
7916
Georg Brandl14404b62008-01-19 19:27:05 +00007917- Issue #1679: "0x" was taken as a valid integer literal.
7918
Georg Brandl6caad7d2008-01-26 14:19:22 +00007919- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007920 added.
7921
Christian Heimesc94e2b52008-01-14 04:13:37 +00007922- sys.float_info / PyFloat_GetInfo: The floating point information
7923 object was converted from a dict to a specialized structseq object.
7924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Patch #1816: Added sys.flags structseq. It exposes the status of
7926 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007927
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928- Objects/structseq.c: Implemented new structseq representation. The
7929 patch makes structseqs (e.g. the return value of os.stat) more
7930 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007931
Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- Patch #1700288: added a type attribute cache that caches method
7933 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007934
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007935- Bug #1776: __import__() no longer accepts filenames on any platform.
7936 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007937
Georg Brandlaed6c662008-01-07 17:25:53 +00007938- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7939
Georg Brandl3ee81df2008-05-17 18:14:43 +00007940- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7941 envvar and sys.dont_write_bytecode attribute. All these can be set
7942 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007943
Georg Brandl3ee81df2008-05-17 18:14:43 +00007944- Improve some exception messages when Windows fails to load an
7945 extension module. Now we get for example '%1 is not a valid Win32
7946 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007947
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007950- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7951 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007952
Christian Heimes0a8143f2007-12-18 23:22:54 +00007953- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007954 and INF. float("nan"), float("inf") and float("-inf") now work on
7955 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007956
Georg Brandl3ee81df2008-05-17 18:14:43 +00007957- Compiler now generates simpler and faster code for dictionary
7958 literals. The oparg for BUILD_MAP now indicates an estimated
7959 dictionary size. There is a new opcode, STORE_MAP, for adding
7960 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Issue #1620: New property decorator syntax was modifying the
7965 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007966
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- Issue #1538: Avoid copying string in split/rsplit if the split char
7968 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007969
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007970- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007971 SystemError.
7972
Nick Coghlanef01d822007-12-03 12:55:17 +00007973- PEP 366: Allow explicit relative imports when executing modules
7974 inside packages with the -m switch via a new module level
7975 __package__ attribute.
7976
Georg Brandl3ee81df2008-05-17 18:14:43 +00007977- Issue #1402: Fix a crash on exit, when another thread is still
7978 running, and if the deallocation of its frames somehow calls the
7979 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007980

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007984 attribute of an empty cell object.
7985
Georg Brandl3ee81df2008-05-17 18:14:43 +00007986- Issue #1460: The utf-7 incremental decoder did not accept truncated
7987 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007988
Georg Brandl3ee81df2008-05-17 18:14:43 +00007989- Patch #1739468: Directories and zipfiles containing a __main__.py
7990 file can now be directly executed by passing their name to the
7991 interpreter. The directory/zipfile is automatically inserted as the
7992 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Issue #1265: Fix a problem with sys.settrace, if the tracing
7995 function uses a generator expression when at the same time the
7996 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007997
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007998- sets and frozensets now have an isdisjoint() method.
7999
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008000- optimize the performance of builtin.sum().
8001
Neal Norwitz44f326e2007-10-05 05:29:17 +00008002- Fix warnings found by the new version of the Coverity checker.
8003
Georg Brandl21e99f42010-03-07 15:23:59 +00008004- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8006 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008007
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008- Issue #1686386: Tuple's tp_repr did not take into account the
8009 possibility of having a self-referential tuple, which is possible
8010 from C code. Nor did object's tp_str consider that a type's tp_str
8011 could do something that could lead to an inifinite recursion.
8012 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8013 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008014
Georg Brandl3ee81df2008-05-17 18:14:43 +00008015- Issue #1164: It was possible to trigger deadlock when using the
8016 'print' statement to write to a file since the GIL was not released
8017 as needed. Now PyObject_Print() does the right thing along with
8018 various tp_print implementations of the built-in types and those in
8019 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008020
Georg Brandl3ee81df2008-05-17 18:14:43 +00008021- Issue #1147: Exceptions were directly allowing string exceptions in
8022 their throw() method even though string exceptions no longer
8023 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008024
Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Issue #1096: Prevent a segfault from getting the repr of a very
8026 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008027
Brett Cannon1e534b52007-09-07 04:18:30 +00008028- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008029 PyObject_Call() never calling back out to Python code to trigger
8030 recursion depth updates/checks. Required the creation of a static
8031 RuntimeError instance in case normalizing an exception put the
8032 recursion check value past its limit. Fixes crashers
8033 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- Patch #1031213: Decode source line in SyntaxErrors back to its
8036 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00008038- Patch #1673759: add a missing overflow check when formatting floats
8039 with %G.
8040
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041- Prevent expandtabs() on string and unicode objects from causing a
8042 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008043

Georg Brandla5ea6892007-06-01 11:33:33 +00008047
Neal Norwitz0ac60192007-05-27 04:08:54 +00008048- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008049 __*__ attributes. (Some already existed, e.g., __doc__ and
8050 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008051
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008052- Add -3 option to the interpreter to warn about features that are
8053 deprecated and will be changed/removed in Python 3.0.
8054
Georg Brandl2134e752007-05-21 20:34:16 +00008055- Patch #1686487: you can now pass any mapping after '**' in function
8056 calls.
8057
Collin Winter62903052007-05-18 23:11:24 +00008058- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008059 "except E as target:". This is to provide forwards compatibility
8060 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008061
Brett Cannon229cee22007-05-05 01:34:02 +00008062- Deprecate BaseException.message as per PEP 352.
8063
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008065 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008066
Vinay Sajip8549ce32007-05-06 17:53:37 +00008067- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008068 setting a plain string, ie don't expand to single letter identifiers.
8069
Raymond Hettinger13936692007-04-11 18:40:58 +00008070- Request #1191699: Slices can now be pickled.
8071
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008072- Request #1193128: str.translate() now allows a None argument for
8073 translations that only remove characters without re-mapping the
8074 remaining characters.
8075
Georg Brandl5cb76c12007-03-21 09:00:39 +00008076- Patch #1682205: a TypeError while unpacking an iterable is no longer
8077 masked by a generic one with the message "unpack non-sequence".
8078
Neal Norwitzaa754b72007-03-21 06:39:48 +00008079- Remove unused file Python/fmod.c.
8080
Guido van Rossum143b5642007-03-23 04:58:42 +00008081- Bug #1683368: The object.__init__() and object.__new__() methods are
8082 now stricter in rejecting excess arguments. The only time when
8083 either allows excess arguments is when it is not overridden and the
8084 other one is. For backwards compatibility, when both are
8085 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008086 warning later). Also, type.__init__() insists on the same signature
8087 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008088
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8090 object to complex using its __complex__() method before falling back
8091 to the __float__() method. Therefore, the functions in the cmath
8092 module now can operate on objects that define a __complex__()
8093 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Patch #1623563: allow __class__ assignment for classes with
8096 __slots__. The old and the new class are still required to have the
8097 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Patch #1642547: Fix an error/crash when encountering syntax errors
8100 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008102- Patch #1462488: Python no longer segfaults when
8103 ``object.__reduce_ex__()`` is called with an object that is faking
8104 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008109- Patch #1444529: the builtin compile() now accepts keyword arguments.
8110
Georg Brandl7b9c5552007-03-12 14:30:05 +00008111- Bug #1678647: write a newline after printing an exception in any
8112 case, even when converting the value to a string failed.
8113
Georg Brandl871f1bc2007-03-12 13:17:36 +00008114- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115 its argument, if it exists. If not, it will work like before. This
8116 allows customizing the output of dir() in the presence of a
8117 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008118
Collin Winter276887b2007-03-12 16:11:39 +00008119- Patch #922167: Python no longer segfaults when faced with infinitely
8120 self-recursive reload() calls (as reported by bug #742342).
8121
Georg Brandl3ee81df2008-05-17 18:14:43 +00008122- Patch #1675981: remove unreachable code from ``type.__new__()``
8123 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008125- Patch #1491866: change the complex() constructor to allow
8126 parthensized forms. This means complex(repr(x)) now works instead of
8127 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008128
Georg Brandlaa2321b2007-03-07 00:40:28 +00008129- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130 makes the filenames the warning module prints much more sensible
8131 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008132
Georg Brandl49aafc92007-03-07 00:34:46 +00008133- Variant of patch #697613: don't exit the interpreter on a SystemExit
8134 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008135 variable is given, but break into the interactive interpreter just
8136 like on other exceptions or normal program exit.

8637 (as opposed to the command line) will now write file names ending in
8638 ".cpp" too.
8639
Facundo Batistad918a652007-04-24 13:54:38 +00008640- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008641 the client's request was successfully received, understood, and
8642 accepted. Now in these cases no error is raised in urllib (issue
8643 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008644

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008651- Added a timeout parameter to the constructor of other protocols
8652 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8653 work started with create_connection() and timeout in httplib, and
8654 closes patch #723312.
8655
Vinay Sajip8549ce32007-05-06 17:53:37 +00008656- Patch #1676823: Added create_connection() to socket.py, which may be
8657 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008658 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008659
Martin v. Löwis0af33882007-03-23 13:27:15 +00008660- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8680
Georg Brandlf66b6032007-03-14 08:27:52 +00008681- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008682 AttributeError instead of an IOError when the server's response
8683 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008684
Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Patch #957650: "%var%" environment variable references are now
8686 properly expanded in ntpath.expandvars(), also "~user" home
8687 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008688
Georg Brandl3ee81df2008-05-17 18:14:43 +00008689- Patch #1429539: pdb now correctly initializes the __main__ module
8690 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008691 correctly now.
8692
Georg Brandlbad6f192007-03-13 21:32:56 +00008693- The nonobvious commands.getstatus() function is now deprecated.

8699
Georg Brandl3ee81df2008-05-17 18:14:43 +00008700- Patch #1530482: add pydoc.render_doc() which returns the
8701 documentation for a thing instead of paging it to stdout, which
8702 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008703
Georg Brandl3ee81df2008-05-17 18:14:43 +00008704- Patch #1533909: the timeit module now accepts callables in addition

8710 parameter which can be set to False to prevent the default
8711 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008712
Georg Brandl9e6b4702007-03-13 18:15:41 +00008713- Patch #1581073: add a flag to textwrap that prevents the dropping of
8714 whitespace while wrapping.
8715
Georg Brandl92a6bae2007-03-13 17:43:32 +00008716- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008717 are set for invalid interpolation sequences that would lead to
8718 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008719

Collin Winter22c42ba2007-03-10 02:51:26 +00008753

8761 returned string up to the first NUL character.
8762

8772
Georg Brandl3ee81df2008-05-17 18:14:43 +00008773- unittest now verifies more of its assumptions. In particular,
8774 TestCase and TestSuite subclasses (not instances) are no longer
8775 accepted in TestSuite.addTest(). This should cause no
8776 incompatibility since it never made sense with ordinary subclasses
8777 -- the failure just occurred later, with a more cumbersome
8778 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008779

8787 given a unicode argument and os.listdir() returns unicode filenames.
8788
Georg Brandl3ee81df2008-05-17 18:14:43 +00008789- Patch #1673619: setup.py identifies extension modules it doesn't

8791 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009160- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009161 time so that opening a database previously created with the DB_DUP
9162 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9163 opens. Specifically: dictionary assignment to a DB object will
9164 replace all values for a given key when the database allows
9165 duplicate values. DB users should use DB.put(k, v) when they want
9166 to store duplicates; not DB[k] = v.

9173 characters with ASCII value less than 32. Also, it correctly quotes
9174 dots only if they occur on a single line, as opposed to the previous
9175 behavior of quoting dots if they are the second character of any
9176 line.
