885 the default C compiler by setting the CC environment variable,
886 Distutils will now attempt to compile extension modules with clang
887 if gcc-4.2 is required but not found. Also as a convenience, if
888 the user does explicitly set CC, substitute its value as the default
889 compiler in the Distutils LDSHARED configuration variable for OS X.
890 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
891 SDK, neither of which are available in Xcode 4. This change does not
892 attempt to override settings to support their use with Xcode 4.)

1169 environment after Distutils set it. Instead, have Distutils set the the
1170 deployment target only in the environment of each build subprocess. It is
1171 still possible to globally override the default by setting
1172 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1173 greater or equal to the default value, the value with which the interpreter
1174 was built.

1204 the ticker doesn't have to wind down to zero from the old starting point
1205 before the new interval takes effect. And if the user increases the
1206 interval, it makes sure the new limit takes effect right away rather have an
1207 early task switch before recognizing the new interval.

2159 This prevents user-created self-referencing ordered dictionaries from
2160 becoming permanently uncollectable GC garbage. The downside is that

2621
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002622- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2623 start byte and the continuation byte(s) are now considered invalid, instead
2624 of the number of bytes specified by the start byte.
2625 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2626 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2627 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2628 Previous versions returned a single u'\ufffd'.
2629
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002630- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002631 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2632 arises from the "Overriding __eq__ blocks inheritance ..." warning
2633 when turned into an exception: in this case the exception simply
2634 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002635
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002636- Issue #8748: Fix two issues with comparisons between complex and integer
2637 objects. (1) The comparison could incorrectly return True in some cases
2638 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2639 (2) The comparison raised an OverflowError for large integers, leading
2640 to unpredictable exceptions when combining integers and complex objects
2641 in sets or dicts.
2642
Mark Dickinson81336372010-05-30 12:12:25 +00002643- Issue #5211: Implicit coercion for the complex type is now completely
2644 removed. (Coercion for arithmetic operations was already removed in 2.7
2645 alpha 4, but coercion for rich comparisons was accidentally left in.)
2646
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002647- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2648 and error handler, instead of writing to the C stderr file in utf-8
2649
Georg Brandlfee0f442010-05-22 21:26:21 +00002650- Issue #7902: When using explicit relative import syntax, don't try implicit
2651 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00002652
Georg Brandlfee0f442010-05-22 21:26:21 +00002653- Issue #7079: Fix a possible crash when closing a file object while using it
2654 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00002656- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00002657 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00002662- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
2663 of the interpreter to set sys.argv without also modifying sys.path. This
2664 helps fix `CVE-2008-5983

Georg Brandlfee0f442010-05-22 21:26:21 +00002882- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2883 the method could block indefinitely if called just before the event loop
2884 started running. This also fixes the occasional freezes witnessed in
2885 test_httpservers.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003008- Issue #7301: Add environment variable $PYTHONWARNINGS.
3009
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003010- Issue #8329: Don't return the same lists from select.select when no fds are
3011 changed.
3012
Georg Brandlfee0f442010-05-22 21:26:21 +00003013- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003014 on 64-bit machines. The shift count for either left or right shift is
3015 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00003023- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3024 with a non-empty format string. This is an effort to future-proof user
3025 code. If a derived class does not currently implement __format__ but later
3026 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003027 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003028 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003061- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00003078- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3079 InvalidOperation instead of returning False. (Comparisons involving a quiet
3080 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3081 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003082
Georg Brandlfee0f442010-05-22 21:26:21 +00003083- Issue #2531: Comparison operations between floats and Decimal instances now
3084 return a result based on the numeric values of the operands; previously they
3085 returned an arbitrary result based on the relative ordering of id(float) and
3086 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003089 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandlfee0f442010-05-22 21:26:21 +00003100- Comparisons using one of <, <=, >, >= between a complex instance and a
3101 Fractions instance now raise TypeError instead of returning True/False. This
3102 makes Fraction <=> complex comparisons consistent with int <=> complex, float

3466 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3467 returning NULL. The macro now returns a statically allocated empty string
3468 instead.

3478 strings,
3479 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3480 numeric strings corresponding to subnormal values,
3481 (3) a memory leak for some values large enough to cause overflow, and
3482 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003513- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003514 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003520- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003521 file position when calling `truncate()`. It would previously change the file
3522 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003523 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3524

3526 class used to represent files stored inside an archive. The new
3527 implementation is significantly faster and can be wrapped in a
3528 ``io.BufferedReader`` object for more speedups. It also solves an issue
3529 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003540- Issue #7748: Since unicode values are supported for some metadata options in
3541 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3542 encoded string for them. This ensures that the upload and register commands
3543 send the correct values to PyPI without any error.

3625
Mark Dickinson1b34d252010-01-01 17:27:30 +00003626- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003627 DeprecationWarning when passed a float argument where an integer was expected.
3628 These functions and methods now raise TypeError instead. The majority of the
3629 effects of this change are in the extension modules, but some core functions
3630 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3631 and many unicode/str methods.

3646 least on IEEE 754 platforms), and in particular does not depend on the
3647 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003814- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3815 decimal string that's guaranteed to round back to x under correct rounding
3816 (with round-half-to-even rounding mode). Previously it gave a string based on
3817 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3818 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3819 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003821- Issue #7117: On almost all platforms: float-to-string and string-to-float
3822 conversions within Python are now correctly rounded. Places these conversions
3823 occur include: str for floats and complex numbers; the float and complex
3824 constructors; old-style and new-style numeric formatting; serialization and
3825 deserialization of floats and complex numbers using marshal, pickle and json;
3826 parsing of float and imaginary literals in Python code; Decimal-to-float
3827 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003828
Georg Brandlba83f822010-03-14 09:50:54 +00003829 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3830 providing correctly-rounded strtod and dtoa C functions. This code is
3831 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3832 the C compiler. There may be a small number of platforms on which correct
3833 operation of this code cannot be guaranteed, so the code is not used: notably,
3834 this applies to platforms where the C double format is not IEEE 754 binary64,
3835 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3836 and Python's configure script is unable to determine how to change the FPU
3837 precision. On these platforms conversions use the platform strtod and dtoa,
3838 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003840- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3841 uses the correctly-rounded string <-> float conversions described above (when
3842 available), and so produces correctly rounded results that will display nicely
3843 under the float repr. There are two related small changes: (1) round now
3844 accepts any class with an ``__index__()`` method for its second argument (but
3845 no longer accepts floats for the second argument), and (2) an excessively
3846 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3847 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004065 untrackable objects are not tracked by the garbage collector. This can reduce
4066 the size of collections and therefore the garbage collection overhead on
4067 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00004140- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4141 existing .py counterpart, override the co_filename attributes of all code

4197
Georg Brandlba83f822010-03-14 09:50:54 +00004198- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4199 file objects with closefd=False. The file descriptor is still kept open but
4200 the file object behaves like a closed file. The ``FileIO`` object also got a
4201 new readonly attribute ``closefd``.

4226 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00004252- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4253 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4254 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4255 of using the replace error handler in PyUnicode_DecodeUTF8().
4256
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004257- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005630- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5632 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5633 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00005731 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5732 for catch_warnings() also led to an improvement in the raising of a
5733 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005799What's New in Python 2.6 beta 3?
5800================================
5801
Barry Warsaw07a4a382008-08-21 01:15:08 +00005802*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005803
5804Core and Builtins
5805-----------------
5806
Guido van Rossumf8402962008-08-20 15:01:50 +00005807- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5808 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5809 extensions do not automatically benefit from the class attribute
5810 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5811 to their tp_flags field if they care. This is a backwards
5812 compatibility feature; in 3.0, all types will use the cache by
5813 default.
5814
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005815- Keyword arguments can now follow starred arguments. (``f(a, *args,
5816 keyword=23)`` is now valid syntax.)
5817
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005818- ctypes function pointers that are COM methods have a boolean True
5819 value again.
5820
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005821- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5822 by denying s# to parse objects that have a releasebuffer procedure,
5823 and introducing s*.
5824
Georg Brandl1e13ea92008-08-11 09:07:59 +00005825- Issue #3537: Fix an assertion failure when an empty but presized dict
5826 object was stored in the freelist.
5827
Mark Dickinsonb6467572008-08-04 21:30:09 +00005828- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5829 ValueError consistently across platforms.
5830
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005831- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5832 (64bit Unix, for example), unichr() would truncate its argument and return
5833 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5834
Neal Norwitze7d8be82008-07-31 17:17:14 +00005835- Apply security patches from Apple.
5836
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005837- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5838 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5839
Antoine Pitrou92f82162008-07-25 22:22:08 +00005840- Issue #1819: function calls with several named parameters are now on
5841 average 35% faster (as measured by pybench).
5842
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005843- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5844 the python debugger steps into a class statement: the free variables (local
5845 variables defined in an outer scope) would be deleted from the outer scope.
5846
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005847- Issue #2620: Overflow checking when allocating or reallocating memory
5848 was not always being done properly in some python types and extension
5849 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5850 all been updated to perform better checks and places in the code that
5851 would previously leak memory on the error path when such an allocation
5852 failed have been fixed.
5853

5855-------
5856
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005857- Issue #3612: Added some missing basic types in ctypes.wintypes.
5858
Benjamin Petersone977ad42008-08-20 01:42:01 +00005859- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5860 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5861
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005862- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5863 version reported by these tools does not necessarily follow the python
5864 version numbering scheme, so the module is less strict when parsing it.
5865
Nick Coghlanf70385a2008-08-18 12:42:46 +00005866- Issue #2235: Added Py3k warnings for types which will become unhashable
5867 under the stricter __hash__ inheritance rules in 3.0. Several types
5868 which did not meet the rules for hash invariants and were already
5869 unhashable in 3.0 have now been explicitly flagged as unhashable in
5870 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5871 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5872
Brett Cannon88f801d2008-08-18 00:46:22 +00005873- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5874 imported into the module but exposed as part of the module's API.
5875
Brett Cannon7b96f072008-08-18 00:41:11 +00005876- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5877
Brett Cannon46225e72008-08-18 00:36:52 +00005878- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005880- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5881
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005882- Issue #3575: Incremental decoder's decode function now takes bytearray
5883 by using 's*' instead of 't#'.
5884
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005885- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005886 fails unicode conversion on 2nd parameter. (windows only)
5887
Georg Brandl222e2082010-08-01 22:27:39 +00005888- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005889 in a redirect.
5890
Brett Cannonabe423e2008-08-16 21:47:07 +00005891- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005892 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005893
Facundo Batistaeb90b782008-08-16 14:44:07 +00005894- Issue #2776: fixed small issue when handling an URL with double slash
5895 after a 302 response in the case of not going through a proxy.
5896
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005897- Issue #2676: in the email package, content-type parsing was hanging on
5898 pathological input because of quadratic or exponential behaviour of a
5899 regular expression.
5900
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005901- Issue #3476: binary buffered reading through the new "io" library is now
5902 thread-safe.
5903
Brett Cannonbf3157b2008-08-14 05:00:03 +00005904- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5905 since mimetools itself is deprecated. Because modules are cached, all
5906 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5907
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005908- Issue #3134: shutil referenced undefined WindowsError symbol.
5909
Robert Schuppenies14646332008-08-10 11:01:53 +00005910- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5911 menu entries were not deleted.
5912
Brett Cannon83e81842008-08-09 23:30:55 +00005913- Copied the implementation of reduce() to _functools.reduce() to have a
5914 version that did not raise a DeprecationWarning under -3.
5915
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005916- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5917 a MemoryError rather than silently stop the iteration.
5918
Guido van Rossum59ce9012008-08-09 14:55:34 +00005919- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5920 to _sre.compile() will now be rejected. This should not affect anybody
5921 since the re.compile() function never generates invalid re-bytecode.
5922
Skip Montanaroa032bf42008-08-08 22:52:51 +00005923- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5924 upon first access it can be automatically initialized from the csv file if
5925 it wasn't initialized during instantiation.
5926
Brett Cannon3aa2a492008-08-06 22:28:09 +00005927- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5928 the reload() built-in has been removed.
5929
Brett Cannon7e30b672008-08-04 21:52:25 +00005930- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005931 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005932 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

5934 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5935 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5936 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005937

Antoine Pitroude781a42008-08-09 12:43:23 +00005942 asking for a specific length. This problem only affected files opened

5999-----------------
6000
Georg Brandl3e483f62008-07-16 22:57:41 +00006001- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6002 its methods now allow for items objects that can be converted to
6003 an integer using operator.index().
6004
Mark Dickinson64b7e502008-07-16 09:40:03 +00006005- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6006 produced a ValueError instead of giving the correct float.
6007
Eric Smitha5fa5a22008-07-16 00:11:49 +00006008- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6009 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6010
Mark Dickinson7103aa42008-07-15 19:08:33 +00006011- Issue #3008: the float type has a new instance method 'float.hex'
6012 and a new class method 'float.fromhex' to convert floating-point
6013 numbers to and from hexadecimal strings, respectively.
6014
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006015- Issue #2235: __hash__ is once again inherited by default. To allow
6016 collections.Hashable to remain meaningful in the presence of the
6017 default hash implementation (object.__hash__), it is now possible
6018 to explicit block inheritance of hash by setting __hash__=None at
6019 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6020 level.
6021
Nick Coghlanb028f502008-07-13 14:52:36 +00006022- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6023 the parent module cannot be found while performing an absolute import.
6024 This means that an incorrectly defined __package__ attribute will
6025 now only prevent relative imports in that module rather than causing
6026 all imports from that module to fail.
6027
Nick Coghlan14ff9942008-07-08 14:21:42 +00006028- Issue #2517: Allow unicode messages in Exceptions again by correctly

6038 another thread's dictionary.
6039
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006040- Issue #3004: Minor change to slice.indices(): the start and stop
6041 arguments are now treated identically, making the behaviour easier
6042 to describe and understand. For example, slice(None, -10,
6043 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6044 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6045 10, -1).
6046
Georg Brandl278fc502008-07-19 12:46:12 +00006047- Issue #3219: Calling a function with repeated keyword arguments,
6048 f(a=2, a=23), would not cause a syntax error. This was a regression
6049 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00006051- Issue #2862: Make int and float freelist management consistent with
6052 other freelists. Changes their CompactFreeList apis into

6059 api functions without holding the GIL, which could lead to a fatal
6060 error when they failed.
6061
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006062- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006087- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6088 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006089 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006090 content-length. The problem had been corrected in the 2.4 branch, but never
6091 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006106- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6107 handling is now the same as that of other special attributes like __name__).
6108
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006109- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Christian Heimes7a990612008-05-26 13:15:11 +00006520
6521- The PyString functions have been renamed to PyBytes. A batch of
6522 defines were added so that the linker still sees the original
6523 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- Issue #1631171: Re-implement the 'warnings' module in C (the
6562 original Python code has been kept as backup). This will allow for
6563 using the 'warning's machinery in such places as the parser where
6564 use of pure Python code is not possible. Both the ``showarning()``
6565 and ``formatwarning()`` gain an optional 'line' argument which is
6566 not called by default for backwards-compatibility reasons. Setting
6567 ``warnings.showwarning()`` to an implementation that lacks support
6568 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006611 extension modules between 32 and 64 bit platforms. See the distutls

6624 so the controlled environment will more closely mirror the typical
6625 script environment. This supports setup.py scripts that refer to
6626 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006631- Issue #2550: The approach used by client/server code for obtaining
6632 ports to listen on in network-oriented tests has been refined in an
6633 effort to facilitate running multiple instances of the entire
6634 regression test suite in parallel without issue.
6635 test_support.bind_port() has been fixed such that it will always
6636 return a unique port -- which wasn't always the case with the
6637 previous implementation, especially if socket options had been set
6638 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6639 new implementation of bind_port() will actually raise an exception
6640 if it is passed an AF_INET/SOCK_STREAM socket with either the
6641 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6642 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6643 the socket it's been passed. This currently only applies to
6644 Windows. This option prevents any other sockets from binding to the
6645 host/port we've bound to, thus removing the possibility of the
6646 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6647 when a second SOCK_STREAM socket binds and accepts to a host/port
6648 that's already been bound by another socket. The optional preferred
6649 port parameter to bind_port() has been removed. Under no
6650 circumstances should tests be hard coding ports!
6651
6652 test_support.find_unused_port() has also been introduced, which will
6653 pass a temporary socket object to bind_port() in order to obtain an
6654 unused port. The temporary socket object is then closed and
6655 deleted, and the port is returned. This method should only be used
6656 for obtaining an unused port in order to pass to an external program
6657 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6658 a parameter to a server-oriented class that doesn't give you direct
6659 access to the underlying socket used.
6660
6661 Finally, test_support.HOST has been introduced, which should be used
6662 for the host argument of any relevant socket calls (i.e. bind and
6663 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006664
6665 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006666 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006667 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6668 test_asynchat and test_socket_ssl.
6669
Georg Brandl3ee81df2008-05-17 18:14:43 +00006670 It is now possible for multiple instances of the regression test
6671 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00006949
Eric Smitha73fbe72008-02-23 03:09:44 +00006950- Added the future_builtins module, which contains hex() and oct().
6951 These are the PEP 3127 version of these functions, designed to be
6952 compatible with the hex() and oct() builtins from Python 3.0. They
6953 differ slightly in their output formats from the existing, unchanged
6954 Python 2.6 builtins. The expected usage of the future_builtins
6955 module is:
6956 from future_builtins import hex, oct
6957
Eric Smith7ef40bf2008-02-20 23:34:22 +00006958- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6959 exponents for exponents with absolute value < 100. Follows C99
6960 standard. This is a change on Windows, which would use 3 digits.
6961 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6962 so that any alterations it does to the resulting string will be
6963 available in stringlib/formatter.h (for float.__format__).
6964
Eric Smith5a3c1352008-02-19 13:21:56 +00006965- Implemented PEP 3101, Advanced String Formatting. This adds a new
6966 builtin format(); a format() method for str and unicode; a
6967 __format__() method to object, str, unicode, int, long, float, and
6968 datetime; the class string.Formatter; and the C API
6969 PyObject_Format().
6970
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971- Fixed several potential crashes, all caused by specially crafted
6972 __del__ methods exploiting objects in temporarily inconsistent
6973 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006974
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006975- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006976 prevent a possible crash: an Abstract Base Class would try to access
6977 a slot on a registered virtual subclass.

6984 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006985
Georg Brandl3ee81df2008-05-17 18:14:43 +00006986- Issue #2045: Fix an infinite recursion triggered when printing a
6987 subclass of collections.defaultdict, if its default_factory is set
6988 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006989
Christian Heimesf75dbef2008-02-08 00:11:31 +00006990- Fixed a minor memory leak in dictobject.c. The content of the free
6991 list was not freed on interpreter shutdown.
6992

6999
Georg Brandl3ee81df2008-05-17 18:14:43 +00007000- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7001 calls. Python expected the return type int but the fork familie
7002 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007003

Georg Brandl3ee81df2008-05-17 18:14:43 +00007016- Patch #1473257: generator objects gain a gi_code attribute. This is
7017 the same object as the func_code attribute of the function that
7018 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007019
Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Issue #1920: "while 0" statements were completely removed by the
7021 compiler, even in the presence of an "else" clause, which is
7022 supposed to be run when the condition is false. Now the compiler
7023 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007024
Guido van Rossumeead05f2008-01-24 18:21:02 +00007025- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007029- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007030 suppressed while an extension is loaded by calling SetErrorMode in
7031 dynload_win.c. The error is still reported properly.
7032
Georg Brandl3ee81df2008-05-17 18:14:43 +00007033- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007034 several extension methods and modules do not work without unicode
7035 support.
7036
Georg Brandl26543b12008-01-21 18:36:51 +00007037- Issue #1882: when compiling code from a string, encoding cookies in the
7038 second line of code were not always recognized correctly.
7039
Georg Brandl14404b62008-01-19 19:27:05 +00007040- Issue #1679: "0x" was taken as a valid integer literal.
7041
Georg Brandl6caad7d2008-01-26 14:19:22 +00007042- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007043 added.
7044
Christian Heimesc94e2b52008-01-14 04:13:37 +00007045- sys.float_info / PyFloat_GetInfo: The floating point information
7046 object was converted from a dict to a specialized structseq object.
7047
Georg Brandl3ee81df2008-05-17 18:14:43 +00007048- Patch #1816: Added sys.flags structseq. It exposes the status of
7049 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007050
Georg Brandl3ee81df2008-05-17 18:14:43 +00007051- Objects/structseq.c: Implemented new structseq representation. The
7052 patch makes structseqs (e.g. the return value of os.stat) more
7053 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007054
Georg Brandl3ee81df2008-05-17 18:14:43 +00007055- Patch #1700288: added a type attribute cache that caches method
7056 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007057
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007058- Bug #1776: __import__() no longer accepts filenames on any platform.
7059 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007060
Georg Brandlaed6c662008-01-07 17:25:53 +00007061- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7062
Georg Brandl3ee81df2008-05-17 18:14:43 +00007063- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7064 envvar and sys.dont_write_bytecode attribute. All these can be set
7065 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007066
Georg Brandl3ee81df2008-05-17 18:14:43 +00007067- Improve some exception messages when Windows fails to load an
7068 extension module. Now we get for example '%1 is not a valid Win32
7069 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007070
Georg Brandl3ee81df2008-05-17 18:14:43 +00007071- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007073- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7074 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007075
Christian Heimes0a8143f2007-12-18 23:22:54 +00007076- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007077 and INF. float("nan"), float("inf") and float("-inf") now work on
7078 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007079
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080- Compiler now generates simpler and faster code for dictionary
7081 literals. The oparg for BUILD_MAP now indicates an estimated
7082 dictionary size. There is a new opcode, STORE_MAP, for adding
7083 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007084
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00007086
Georg Brandl3ee81df2008-05-17 18:14:43 +00007087- Issue #1620: New property decorator syntax was modifying the
7088 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007089
Georg Brandl3ee81df2008-05-17 18:14:43 +00007090- Issue #1538: Avoid copying string in split/rsplit if the split char
7091 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007092
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007093- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007094 SystemError.
7095
Nick Coghlanef01d822007-12-03 12:55:17 +00007096- PEP 366: Allow explicit relative imports when executing modules
7097 inside packages with the -m switch via a new module level
7098 __package__ attribute.
7099
Georg Brandl3ee81df2008-05-17 18:14:43 +00007100- Issue #1402: Fix a crash on exit, when another thread is still
7101 running, and if the deallocation of its frames somehow calls the
7102 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007103

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007107 attribute of an empty cell object.
7108
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109- Issue #1460: The utf-7 incremental decoder did not accept truncated
7110 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007111
Georg Brandl3ee81df2008-05-17 18:14:43 +00007112- Patch #1739468: Directories and zipfiles containing a __main__.py
7113 file can now be directly executed by passing their name to the
7114 interpreter. The directory/zipfile is automatically inserted as the
7115 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007116
Georg Brandl3ee81df2008-05-17 18:14:43 +00007117- Issue #1265: Fix a problem with sys.settrace, if the tracing
7118 function uses a generator expression when at the same time the
7119 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007120
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007121- sets and frozensets now have an isdisjoint() method.
7122
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007123- optimize the performance of builtin.sum().
7124
Neal Norwitz44f326e2007-10-05 05:29:17 +00007125- Fix warnings found by the new version of the Coverity checker.
7126
Georg Brandl21e99f42010-03-07 15:23:59 +00007127- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007128 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7129 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007130
Georg Brandl3ee81df2008-05-17 18:14:43 +00007131- Issue #1686386: Tuple's tp_repr did not take into account the
7132 possibility of having a self-referential tuple, which is possible
7133 from C code. Nor did object's tp_str consider that a type's tp_str
7134 could do something that could lead to an inifinite recursion.
7135 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7136 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007137
Georg Brandl3ee81df2008-05-17 18:14:43 +00007138- Issue #1164: It was possible to trigger deadlock when using the
7139 'print' statement to write to a file since the GIL was not released
7140 as needed. Now PyObject_Print() does the right thing along with
7141 various tp_print implementations of the built-in types and those in
7142 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007143
Georg Brandl3ee81df2008-05-17 18:14:43 +00007144- Issue #1147: Exceptions were directly allowing string exceptions in
7145 their throw() method even though string exceptions no longer
7146 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007147
Georg Brandl3ee81df2008-05-17 18:14:43 +00007148- Issue #1096: Prevent a segfault from getting the repr of a very
7149 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007150
Brett Cannon1e534b52007-09-07 04:18:30 +00007151- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007152 PyObject_Call() never calling back out to Python code to trigger
7153 recursion depth updates/checks. Required the creation of a static
7154 RuntimeError instance in case normalizing an exception put the
7155 recursion check value past its limit. Fixes crashers
7156 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007157
Georg Brandl3ee81df2008-05-17 18:14:43 +00007158- Patch #1031213: Decode source line in SyntaxErrors back to its
7159 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00007160
Georg Brandl7c3b50d2007-07-12 08:38:00 +00007161- Patch #1673759: add a missing overflow check when formatting floats
7162 with %G.
7163
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Prevent expandtabs() on string and unicode objects from causing a
7165 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007166
Georg Brandl3ee81df2008-05-17 18:14:43 +00007167- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007169- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00007170
Neal Norwitz0ac60192007-05-27 04:08:54 +00007171- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172 __*__ attributes. (Some already existed, e.g., __doc__ and
7173 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007174
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007175- Add -3 option to the interpreter to warn about features that are
7176 deprecated and will be changed/removed in Python 3.0.
7177
Georg Brandl2134e752007-05-21 20:34:16 +00007178- Patch #1686487: you can now pass any mapping after '**' in function
7179 calls.
7180
Collin Winter62903052007-05-18 23:11:24 +00007181- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182 "except E as target:". This is to provide forwards compatibility
7183 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007184
Brett Cannon229cee22007-05-05 01:34:02 +00007185- Deprecate BaseException.message as per PEP 352.
7186
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007188 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007189
Vinay Sajip8549ce32007-05-06 17:53:37 +00007190- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007191 setting a plain string, ie don't expand to single letter identifiers.
7192
Raymond Hettinger13936692007-04-11 18:40:58 +00007193- Request #1191699: Slices can now be pickled.
7194
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007195- Request #1193128: str.translate() now allows a None argument for
7196 translations that only remove characters without re-mapping the
7197 remaining characters.
7198
Georg Brandl5cb76c12007-03-21 09:00:39 +00007199- Patch #1682205: a TypeError while unpacking an iterable is no longer
7200 masked by a generic one with the message "unpack non-sequence".
7201
Neal Norwitzaa754b72007-03-21 06:39:48 +00007202- Remove unused file Python/fmod.c.
7203
Guido van Rossum143b5642007-03-23 04:58:42 +00007204- Bug #1683368: The object.__init__() and object.__new__() methods are
7205 now stricter in rejecting excess arguments. The only time when
7206 either allows excess arguments is when it is not overridden and the
7207 other one is. For backwards compatibility, when both are
7208 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007209 warning later). Also, type.__init__() insists on the same signature
7210 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007211
Georg Brandl3ee81df2008-05-17 18:14:43 +00007212- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7213 object to complex using its __complex__() method before falling back
7214 to the __float__() method. Therefore, the functions in the cmath
7215 module now can operate on objects that define a __complex__()
7216 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007217
Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Patch #1623563: allow __class__ assignment for classes with
7219 __slots__. The old and the new class are still required to have the
7220 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007221
Georg Brandl3ee81df2008-05-17 18:14:43 +00007222- Patch #1642547: Fix an error/crash when encountering syntax errors
7223 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007225- Patch #1462488: Python no longer segfaults when
7226 ``object.__reduce_ex__()`` is called with an object that is faking
7227 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007228
Georg Brandl3ee81df2008-05-17 18:14:43 +00007229- Patch #1680015: Don't modify __slots__ tuple if it contains an
7230 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00007232- Patch #1444529: the builtin compile() now accepts keyword arguments.
7233
Georg Brandl7b9c5552007-03-12 14:30:05 +00007234- Bug #1678647: write a newline after printing an exception in any
7235 case, even when converting the value to a string failed.
7236
Georg Brandl871f1bc2007-03-12 13:17:36 +00007237- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007238 its argument, if it exists. If not, it will work like before. This
7239 allows customizing the output of dir() in the presence of a
7240 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007241
Collin Winter276887b2007-03-12 16:11:39 +00007242- Patch #922167: Python no longer segfaults when faced with infinitely
7243 self-recursive reload() calls (as reported by bug #742342).
7244
Georg Brandl3ee81df2008-05-17 18:14:43 +00007245- Patch #1675981: remove unreachable code from ``type.__new__()``
7246 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007247
Georg Brandl3ee81df2008-05-17 18:14:43 +00007248- Patch #1491866: change the complex() constructor to allow
7249 parthensized forms. This means complex(repr(x)) now works instead of
7250 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007251
Georg Brandlaa2321b2007-03-07 00:40:28 +00007252- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007253 makes the filenames the warning module prints much more sensible
7254 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007255
Georg Brandl49aafc92007-03-07 00:34:46 +00007256- Variant of patch #697613: don't exit the interpreter on a SystemExit
7257 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007258 variable is given, but break into the interactive interpreter just
7259 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00007260
Georg Brandl3ee81df2008-05-17 18:14:43 +00007261- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandlfb4b3b72007-04-24 15:27:13 +00007759- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
7760 (as opposed to the command line) will now write file names ending in
7761 ".cpp" too.
7762
Facundo Batistad918a652007-04-24 13:54:38 +00007763- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007764 the client's request was successfully received, understood, and
7765 accepted. Now in these cases no error is raised in urllib (issue
7766 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007767

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007774- Added a timeout parameter to the constructor of other protocols
7775 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7776 work started with create_connection() and timeout in httplib, and
7777 closes patch #723312.
7778
Vinay Sajip8549ce32007-05-06 17:53:37 +00007779- Patch #1676823: Added create_connection() to socket.py, which may be
7780 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007781 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007782
Martin v. Löwis0af33882007-03-23 13:27:15 +00007783- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7803
Georg Brandlf66b6032007-03-14 08:27:52 +00007804- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007805 AttributeError instead of an IOError when the server's response
7806 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Patch #957650: "%var%" environment variable references are now
7809 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007811
Georg Brandl3ee81df2008-05-17 18:14:43 +00007812- Patch #1429539: pdb now correctly initializes the __main__ module
7813 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007814 correctly now.
7815
Georg Brandlbad6f192007-03-13 21:32:56 +00007816- The nonobvious commands.getstatus() function is now deprecated.

7822
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Patch #1530482: add pydoc.render_doc() which returns the
7824 documentation for a thing instead of paging it to stdout, which
7825 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Patch #1533909: the timeit module now accepts callables in addition

Georg Brandl3ee81df2008-05-17 18:14:43 +00007832- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete"
7833 parameter which can be set to False to prevent the default
7834 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007835
Georg Brandl9e6b4702007-03-13 18:15:41 +00007836- Patch #1581073: add a flag to textwrap that prevents the dropping of
7837 whitespace while wrapping.
7838
Georg Brandl92a6bae2007-03-13 17:43:32 +00007839- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007840 are set for invalid interpolation sequences that would lead to
7841 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007842

Collin Winter22c42ba2007-03-10 02:51:26 +00007876

7884 returned string up to the first NUL character.
7885

7895
Georg Brandl3ee81df2008-05-17 18:14:43 +00007896- unittest now verifies more of its assumptions. In particular,
7897 TestCase and TestSuite subclasses (not instances) are no longer
7898 accepted in TestSuite.addTest(). This should cause no
7899 incompatibility since it never made sense with ordinary subclasses
7900 -- the failure just occurred later, with a more cumbersome
7901 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007902

7910 given a unicode argument and os.listdir() returns unicode filenames.
7911
Georg Brandl3ee81df2008-05-17 18:14:43 +00007912- Patch #1673619: setup.py identifies extension modules it doesn't

7914 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008290 time so that opening a database previously created with the DB_DUP
8291 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8292 opens. Specifically: dictionary assignment to a DB object will
8293 replace all values for a given key when the database allows
8294 duplicate values. DB users should use DB.put(k, v) when they want
8295 to store duplicates; not DB[k] = v.

8302 characters with ASCII value less than 32. Also, it correctly quotes
8303 dots only if they occur on a single line, as opposed to the previous
8304 behavior of quoting dots if they are the second character of any
8305 line.
