13 is modified during the lifetime of the Python process after zipimport has

1596 In particular, fix extension module build failures when trying to use
1597 32-bit-only installer Pythons on systems with Xcode 4 (currently
1598 OS X 10.8, 10.7, and optionally 10.6).
1599 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1600 * Since Xcode 4 removes ppc support, extension module builds now
1601 check for ppc compiler support and by default remove ppc and
1602 ppc64 archs when they are not available.
1603 * Extension module builds now revert to using system installed
1604 headers and libs (/usr and /System/Library) if the SDK used
1605 to build the interpreter is not installed or has moved.
1606 * Try to avoid building extension modules with deprecated
1607 and problematic Apple llvm-gcc compiler. If original compiler
1608 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002032- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002033 has left two versions of customize_compiler, the original in
2034 distutils.sysconfig and another copy in distutils.ccompiler, with some
2035 parts of distutils calling one and others using the other.
2036 Complete the revert back to only having one in distutils.sysconfig as
2037 is the case in 3.x.
2038
Ned Deily0d0ea482012-02-10 12:59:06 +01002039- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2040 Distutils-based packages with C extension modules may fail because
2041 Apple has removed gcc-4.2, the version used to build python.org
2042 64-bit/32-bit Pythons. If the user does not explicitly override
2043 the default C compiler by setting the CC environment variable,
2044 Distutils will now attempt to compile extension modules with clang
2045 if gcc-4.2 is required but not found. Also as a convenience, if
2046 the user does explicitly set CC, substitute its value as the default
2047 compiler in the Distutils LDSHARED configuration variable for OS X.
2048 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2049 SDK, neither of which are available in Xcode 4. This change does not
2050 attempt to override settings to support their use with Xcode 4.)

2118 raised when the wrapped raw file is non-blocking and the write would block.

Ned Deily87e82bb2011-06-28 19:52:59 -07002300- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2301 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2302 interpreter process. This could cause failures in non-Distutils subprocesses
2303 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002304 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002305 deployment target only in the environment of each build subprocess. It is
2306 still possible to globally override the default by setting
2307 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2308 greater or equal to the default value, the value with which the interpreter
2309 was built.

3323 This prevents user-created self-referencing ordered dictionaries from
3324 becoming permanently uncollectable GC garbage. The downside is that

3783-----------------
3784
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003785- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3786 start byte and the continuation byte(s) are now considered invalid, instead
3787 of the number of bytes specified by the start byte.
3788 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3789 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3790 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3791 Previous versions returned a single u'\ufffd'.
3792
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003793- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003794 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3795 arises from the "Overriding __eq__ blocks inheritance ..." warning
3796 when turned into an exception: in this case the exception simply
3797 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003798
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003799- Issue #8748: Fix two issues with comparisons between complex and integer
3800 objects. (1) The comparison could incorrectly return True in some cases
3801 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3802 (2) The comparison raised an OverflowError for large integers, leading
3803 to unpredictable exceptions when combining integers and complex objects
3804 in sets or dicts.
3805
Mark Dickinson81336372010-05-30 12:12:25 +00003806- Issue #5211: Implicit coercion for the complex type is now completely
3807 removed. (Coercion for arithmetic operations was already removed in 2.7
3808 alpha 4, but coercion for rich comparisons was accidentally left in.)
3809
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003810- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3811 and error handler, instead of writing to the C stderr file in utf-8
3812
Georg Brandlfee0f442010-05-22 21:26:21 +00003813- Issue #7902: When using explicit relative import syntax, don't try implicit
3814 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00003815
Georg Brandlfee0f442010-05-22 21:26:21 +00003816- Issue #7079: Fix a possible crash when closing a file object while using it
3817 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00003818
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00003819- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00003820 Window Server again in a framework build on MacOSX 10.5 or earlier.

3824
Georg Brandlfee0f442010-05-22 21:26:21 +00003825- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
3826 of the interpreter to set sys.argv without also modifying sys.path. This
3827 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +00003828 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

3852
R. David Murray52dcd452010-06-02 22:03:15 +00003853- Issue #1368247: set_charset (and therefore MIMEText) now automatically

4174 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00004186- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4187 with a non-empty format string. This is an effort to future-proof user
4188 code. If a derived class does not currently implement __format__ but later
4189 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004190 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004191 Python 3.3 and it will be an error in Python 3.4.

4242 InvalidOperation instead of returning False. (Comparisons involving a quiet
4243 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

4629 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4630 returning NULL. The macro now returns a statically allocated empty string
4631 instead.

4641 strings,
4642 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4643 numeric strings corresponding to subnormal values,
4644 (3) a memory leak for some values large enough to cause overflow, and
4645 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004676- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004677 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004678 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004683- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004684 file position when calling `truncate()`. It would previously change the file
4685 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004686 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4687

4689 class used to represent files stored inside an archive. The new
4690 implementation is significantly faster and can be wrapped in a
4691 ``io.BufferedReader`` object for more speedups. It also solves an issue
4692 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4693 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004703- Issue #7748: Since unicode values are supported for some metadata options in
4704 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4705 encoded string for them. This ensures that the upload and register commands
4706 send the correct values to PyPI without any error.

4788
Mark Dickinson1b34d252010-01-01 17:27:30 +00004789- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004790 DeprecationWarning when passed a float argument where an integer was expected.
4791 These functions and methods now raise TypeError instead. The majority of the
4792 effects of this change are in the extension modules, but some core functions
4793 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4794 and many unicode/str methods.

4809 least on IEEE 754 platforms), and in particular does not depend on the
4810 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004976- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4977 decimal string that's guaranteed to round back to x under correct rounding
4978 (with round-half-to-even rounding mode). Previously it gave a string based on
4979 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4980 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4981 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004983- Issue #7117: On almost all platforms: float-to-string and string-to-float
4984 conversions within Python are now correctly rounded. Places these conversions
4985 occur include: str for floats and complex numbers; the float and complex
4986 constructors; old-style and new-style numeric formatting; serialization and
4987 deserialization of floats and complex numbers using marshal, pickle and json;
4988 parsing of float and imaginary literals in Python code; Decimal-to-float
4989 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004990
Georg Brandlba83f822010-03-14 09:50:54 +00004991 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4992 providing correctly-rounded strtod and dtoa C functions. This code is
4993 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4994 the C compiler. There may be a small number of platforms on which correct
4995 operation of this code cannot be guaranteed, so the code is not used: notably,
4996 this applies to platforms where the C double format is not IEEE 754 binary64,
4997 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4998 and Python's configure script is unable to determine how to change the FPU
4999 precision. On these platforms conversions use the platform strtod and dtoa,
5000 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005002- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5003 uses the correctly-rounded string <-> float conversions described above (when
5004 available), and so produces correctly rounded results that will display nicely
5005 under the float repr. There are two related small changes: (1) round now
5006 accepts any class with an ``__index__()`` method for its second argument (but
5007 no longer accepts floats for the second argument), and (2) an excessively
5008 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5009 raises an exception.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006896 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6897 for catch_warnings() also led to an improvement in the raising of a
6898 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006964What's New in Python 2.6 beta 3?
6965================================
6966
Barry Warsaw07a4a382008-08-21 01:15:08 +00006967*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006968
6969Core and Builtins
6970-----------------
6971
Guido van Rossumf8402962008-08-20 15:01:50 +00006972- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6973 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6974 extensions do not automatically benefit from the class attribute
6975 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6976 to their tp_flags field if they care. This is a backwards
6977 compatibility feature; in 3.0, all types will use the cache by
6978 default.
6979
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006980- Keyword arguments can now follow starred arguments. (``f(a, *args,
6981 keyword=23)`` is now valid syntax.)
6982
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006983- ctypes function pointers that are COM methods have a boolean True
6984 value again.
6985
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006986- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6987 by denying s# to parse objects that have a releasebuffer procedure,
6988 and introducing s*.
6989
Georg Brandl1e13ea92008-08-11 09:07:59 +00006990- Issue #3537: Fix an assertion failure when an empty but presized dict
6991 object was stored in the freelist.
6992
Mark Dickinsonb6467572008-08-04 21:30:09 +00006993- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6994 ValueError consistently across platforms.
6995
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006996- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6997 (64bit Unix, for example), unichr() would truncate its argument and return
6998 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6999
Neal Norwitze7d8be82008-07-31 17:17:14 +00007000- Apply security patches from Apple.
7001
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007002- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7003 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7004
Antoine Pitrou92f82162008-07-25 22:22:08 +00007005- Issue #1819: function calls with several named parameters are now on
7006 average 35% faster (as measured by pybench).
7007
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007008- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7009 the python debugger steps into a class statement: the free variables (local
7010 variables defined in an outer scope) would be deleted from the outer scope.
7011
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007012- Issue #2620: Overflow checking when allocating or reallocating memory
7013 was not always being done properly in some python types and extension
7014 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7015 all been updated to perform better checks and places in the code that
7016 would previously leak memory on the error path when such an allocation
7017 failed have been fixed.

7020-------
7021
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007022- Issue #3612: Added some missing basic types in ctypes.wintypes.
7023
Benjamin Petersone977ad42008-08-20 01:42:01 +00007024- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7025 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7026
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007027- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7028 version reported by these tools does not necessarily follow the python
7029 version numbering scheme, so the module is less strict when parsing it.
7030
Nick Coghlanf70385a2008-08-18 12:42:46 +00007031- Issue #2235: Added Py3k warnings for types which will become unhashable
7032 under the stricter __hash__ inheritance rules in 3.0. Several types
7033 which did not meet the rules for hash invariants and were already
7034 unhashable in 3.0 have now been explicitly flagged as unhashable in
7035 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7036 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7037
Brett Cannon88f801d2008-08-18 00:46:22 +00007038- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7039 imported into the module but exposed as part of the module's API.
7040
Brett Cannon7b96f072008-08-18 00:41:11 +00007041- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7042
Brett Cannon46225e72008-08-18 00:36:52 +00007043- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007045- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7046
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007047- Issue #3575: Incremental decoder's decode function now takes bytearray
7048 by using 's*' instead of 't#'.
7049
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007050- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007051 fails unicode conversion on 2nd parameter. (windows only)
7052
Georg Brandl222e2082010-08-01 22:27:39 +00007053- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007054 in a redirect.
7055
Brett Cannonabe423e2008-08-16 21:47:07 +00007056- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007057 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007058
Facundo Batistaeb90b782008-08-16 14:44:07 +00007059- Issue #2776: fixed small issue when handling an URL with double slash
7060 after a 302 response in the case of not going through a proxy.
7061
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007062- Issue #2676: in the email package, content-type parsing was hanging on
7063 pathological input because of quadratic or exponential behaviour of a
7064 regular expression.
7065
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007066- Issue #3476: binary buffered reading through the new "io" library is now
7067 thread-safe.
7068
Brett Cannonbf3157b2008-08-14 05:00:03 +00007069- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7070 since mimetools itself is deprecated. Because modules are cached, all
7071 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7072
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007073- Issue #3134: shutil referenced undefined WindowsError symbol.
7074
Robert Schuppenies14646332008-08-10 11:01:53 +00007075- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7076 menu entries were not deleted.
7077
Brett Cannon83e81842008-08-09 23:30:55 +00007078- Copied the implementation of reduce() to _functools.reduce() to have a
7079 version that did not raise a DeprecationWarning under -3.
7080
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007081- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7082 a MemoryError rather than silently stop the iteration.
7083
Guido van Rossum59ce9012008-08-09 14:55:34 +00007084- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7085 to _sre.compile() will now be rejected. This should not affect anybody
7086 since the re.compile() function never generates invalid re-bytecode.
7087
Skip Montanaroa032bf42008-08-08 22:52:51 +00007088- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7089 upon first access it can be automatically initialized from the csv file if
7090 it wasn't initialized during instantiation.
7091
Brett Cannon3aa2a492008-08-06 22:28:09 +00007092- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7093 the reload() built-in has been removed.
7094
Brett Cannon7e30b672008-08-04 21:52:25 +00007095- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007096 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007107 asking for a specific length. This problem only affected files opened

7164-----------------
7165
Georg Brandl3e483f62008-07-16 22:57:41 +00007166- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7167 its methods now allow for items objects that can be converted to
7168 an integer using operator.index().
7169
Mark Dickinson64b7e502008-07-16 09:40:03 +00007170- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7171 produced a ValueError instead of giving the correct float.
7172
Eric Smitha5fa5a22008-07-16 00:11:49 +00007173- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7174 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7175
Mark Dickinson7103aa42008-07-15 19:08:33 +00007176- Issue #3008: the float type has a new instance method 'float.hex'
7177 and a new class method 'float.fromhex' to convert floating-point
7178 numbers to and from hexadecimal strings, respectively.
7179
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007180- Issue #2235: __hash__ is once again inherited by default. To allow
7181 collections.Hashable to remain meaningful in the presence of the
7182 default hash implementation (object.__hash__), it is now possible
7183 to explicit block inheritance of hash by setting __hash__=None at
7184 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7185 level.
7186
Nick Coghlanb028f502008-07-13 14:52:36 +00007187- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7188 the parent module cannot be found while performing an absolute import.
7189 This means that an incorrectly defined __package__ attribute will
7190 now only prevent relative imports in that module rather than causing
7191 all imports from that module to fail.
7192
Nick Coghlan14ff9942008-07-08 14:21:42 +00007193- Issue #2517: Allow unicode messages in Exceptions again by correctly

7203 another thread's dictionary.
7204
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007205- Issue #3004: Minor change to slice.indices(): the start and stop
7206 arguments are now treated identically, making the behaviour easier
7207 to describe and understand. For example, slice(None, -10,
7208 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7209 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7210 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007212- Issue #3219: Calling a function with repeated keyword arguments,
7213 f(a=2, a=23), would not cause a syntax error. This was a regression
7214 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007252- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7253 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007254 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007255 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007271- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7681- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007682
7683- The PyString functions have been renamed to PyBytes. A batch of
7684 defines were added so that the linker still sees the original
7685 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007723- Issue #1631171: Re-implement the 'warnings' module in C (the
7724 original Python code has been kept as backup). This will allow for
7725 using the 'warning's machinery in such places as the parser where
7726 use of pure Python code is not possible. Both the ``showarning()``
7727 and ``formatwarning()`` gain an optional 'line' argument which is
7728 not called by default for backwards-compatibility reasons. Setting
7729 ``warnings.showwarning()`` to an implementation that lacks support
7730 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007772- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007773 extension modules between 32 and 64 bit platforms. See the distutls

7778 file.close() is called while an object is in use by another thread
7779 an IOError exception will be raised and the file will not be closed.
7780
Thomas Hellerf7906482008-04-04 19:43:25 +00007781- The bundled libffi copy is now in sync with the recently released

7786 so the controlled environment will more closely mirror the typical
7787 script environment. This supports setup.py scripts that refer to
7788 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007793- Issue #2550: The approach used by client/server code for obtaining
7794 ports to listen on in network-oriented tests has been refined in an
7795 effort to facilitate running multiple instances of the entire
7796 regression test suite in parallel without issue.
7797 test_support.bind_port() has been fixed such that it will always
7798 return a unique port -- which wasn't always the case with the
7799 previous implementation, especially if socket options had been set
7800 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7801 new implementation of bind_port() will actually raise an exception
7802 if it is passed an AF_INET/SOCK_STREAM socket with either the
7803 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7804 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7805 the socket it's been passed. This currently only applies to
7806 Windows. This option prevents any other sockets from binding to the
7807 host/port we've bound to, thus removing the possibility of the
7808 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7809 when a second SOCK_STREAM socket binds and accepts to a host/port
7810 that's already been bound by another socket. The optional preferred
7811 port parameter to bind_port() has been removed. Under no
7812 circumstances should tests be hard coding ports!
7813
7814 test_support.find_unused_port() has also been introduced, which will
7815 pass a temporary socket object to bind_port() in order to obtain an
7816 unused port. The temporary socket object is then closed and
7817 deleted, and the port is returned. This method should only be used
7818 for obtaining an unused port in order to pass to an external program
7819 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7820 a parameter to a server-oriented class that doesn't give you direct
7821 access to the underlying socket used.
7822
7823 Finally, test_support.HOST has been introduced, which should be used
7824 for the host argument of any relevant socket calls (i.e. bind and
7825 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007826
7827 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007829 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7830 test_asynchat and test_socket_ssl.
7831
Georg Brandl3ee81df2008-05-17 18:14:43 +00007832 It is now possible for multiple instances of the regression test
7833 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008112- Added the future_builtins module, which contains hex() and oct().
8113 These are the PEP 3127 version of these functions, designed to be
8114 compatible with the hex() and oct() builtins from Python 3.0. They
8115 differ slightly in their output formats from the existing, unchanged
8116 Python 2.6 builtins. The expected usage of the future_builtins
8117 module is:
8118 from future_builtins import hex, oct
8119
Eric Smith7ef40bf2008-02-20 23:34:22 +00008120- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8121 exponents for exponents with absolute value < 100. Follows C99
8122 standard. This is a change on Windows, which would use 3 digits.
8123 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8124 so that any alterations it does to the resulting string will be
8125 available in stringlib/formatter.h (for float.__format__).
8126
Eric Smith5a3c1352008-02-19 13:21:56 +00008127- Implemented PEP 3101, Advanced String Formatting. This adds a new
8128 builtin format(); a format() method for str and unicode; a
8129 __format__() method to object, str, unicode, int, long, float, and
8130 datetime; the class string.Formatter; and the C API
8131 PyObject_Format().
8132
Georg Brandl3ee81df2008-05-17 18:14:43 +00008133- Fixed several potential crashes, all caused by specially crafted
8134 __del__ methods exploiting objects in temporarily inconsistent
8135 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008136
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008137- Issue #2115: Important speedup in setting __slot__ attributes. Also

8146 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008147
Georg Brandl3ee81df2008-05-17 18:14:43 +00008148- Issue #2045: Fix an infinite recursion triggered when printing a
8149 subclass of collections.defaultdict, if its default_factory is set
8150 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008151
Christian Heimesf75dbef2008-02-08 00:11:31 +00008152- Fixed a minor memory leak in dictobject.c. The content of the free

8161
Georg Brandl3ee81df2008-05-17 18:14:43 +00008162- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8163 calls. Python expected the return type int but the fork familie
8164 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008178- Patch #1473257: generator objects gain a gi_code attribute. This is
8179 the same object as the func_code attribute of the function that
8180 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008181
Georg Brandl3ee81df2008-05-17 18:14:43 +00008182- Issue #1920: "while 0" statements were completely removed by the
8183 compiler, even in the presence of an "else" clause, which is
8184 supposed to be run when the condition is false. Now the compiler
8185 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008186

8193 dynload_win.c. The error is still reported properly.
8194
Georg Brandl3ee81df2008-05-17 18:14:43 +00008195- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008196 several extension methods and modules do not work without unicode
8197 support.
8198
Georg Brandl26543b12008-01-21 18:36:51 +00008199- Issue #1882: when compiling code from a string, encoding cookies in the
8200 second line of code were not always recognized correctly.
8201
Georg Brandl14404b62008-01-19 19:27:05 +00008202- Issue #1679: "0x" was taken as a valid integer literal.
8203
Georg Brandl6caad7d2008-01-26 14:19:22 +00008204- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008205 added.
8206
Christian Heimesc94e2b52008-01-14 04:13:37 +00008207- sys.float_info / PyFloat_GetInfo: The floating point information
8208 object was converted from a dict to a specialized structseq object.
8209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Patch #1816: Added sys.flags structseq. It exposes the status of
8211 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213- Objects/structseq.c: Implemented new structseq representation. The
8214 patch makes structseqs (e.g. the return value of os.stat) more
8215 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217- Patch #1700288: added a type attribute cache that caches method
8218 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008219
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008220- Bug #1776: __import__() no longer accepts filenames on any platform.
8221 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008222
Georg Brandlaed6c662008-01-07 17:25:53 +00008223- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8224
Georg Brandl3ee81df2008-05-17 18:14:43 +00008225- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8226 envvar and sys.dont_write_bytecode attribute. All these can be set
8227 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008228
Georg Brandl3ee81df2008-05-17 18:14:43 +00008229- Improve some exception messages when Windows fails to load an
8230 extension module. Now we get for example '%1 is not a valid Win32
8231 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008232
Georg Brandl3ee81df2008-05-17 18:14:43 +00008233- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008235- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8236 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008237
Christian Heimes0a8143f2007-12-18 23:22:54 +00008238- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239 and INF. float("nan"), float("inf") and float("-inf") now work on
8240 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Compiler now generates simpler and faster code for dictionary
8243 literals. The oparg for BUILD_MAP now indicates an estimated
8244 dictionary size. There is a new opcode, STORE_MAP, for adding
8245 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Issue #1538: Avoid copying string in split/rsplit if the split char
8253 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008254
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008255- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008256 SystemError.
8257
Nick Coghlanef01d822007-12-03 12:55:17 +00008258- PEP 366: Allow explicit relative imports when executing modules

8260 __package__ attribute.
8261
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262- Issue #1402: Fix a crash on exit, when another thread is still
8263 running, and if the deallocation of its frames somehow calls the
8264 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008265

Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Patch #1739468: Directories and zipfiles containing a __main__.py
8275 file can now be directly executed by passing their name to the
8276 interpreter. The directory/zipfile is automatically inserted as the
8277 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Issue #1265: Fix a problem with sys.settrace, if the tracing
8280 function uses a generator expression when at the same time the
8281 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008282
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008283- sets and frozensets now have an isdisjoint() method.
8284
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008285- optimize the performance of builtin.sum().
8286
Neal Norwitz44f326e2007-10-05 05:29:17 +00008287- Fix warnings found by the new version of the Coverity checker.
8288
Georg Brandl21e99f42010-03-07 15:23:59 +00008289- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008290 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8291 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #1686386: Tuple's tp_repr did not take into account the
8294 possibility of having a self-referential tuple, which is possible
8295 from C code. Nor did object's tp_str consider that a type's tp_str
8296 could do something that could lead to an inifinite recursion.
8297 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8298 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008299
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Issue #1164: It was possible to trigger deadlock when using the
8301 'print' statement to write to a file since the GIL was not released
8302 as needed. Now PyObject_Print() does the right thing along with
8303 various tp_print implementations of the built-in types and those in
8304 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008305
Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Issue #1147: Exceptions were directly allowing string exceptions in
8307 their throw() method even though string exceptions no longer
8308 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008309
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Issue #1096: Prevent a segfault from getting the repr of a very
8311 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008312
Brett Cannon1e534b52007-09-07 04:18:30 +00008313- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008314 PyObject_Call() never calling back out to Python code to trigger
8315 recursion depth updates/checks. Required the creation of a static
8316 RuntimeError instance in case normalizing an exception put the
8317 recursion check value past its limit. Fixes crashers
8318 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008319
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- Patch #1031213: Decode source line in SyntaxErrors back to its

8324 with %G.
8325
Georg Brandl3ee81df2008-05-17 18:14:43 +00008326- Prevent expandtabs() on string and unicode objects from causing a
8327 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008333- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008334 __*__ attributes. (Some already existed, e.g., __doc__ and
8335 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008336
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008337- Add -3 option to the interpreter to warn about features that are
8338 deprecated and will be changed/removed in Python 3.0.
8339
Georg Brandl2134e752007-05-21 20:34:16 +00008340- Patch #1686487: you can now pass any mapping after '**' in function
8341 calls.
8342
Collin Winter62903052007-05-18 23:11:24 +00008343- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 "except E as target:". This is to provide forwards compatibility
8345 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008346
Brett Cannon229cee22007-05-05 01:34:02 +00008347- Deprecate BaseException.message as per PEP 352.
8348
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008350 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008351
Vinay Sajip8549ce32007-05-06 17:53:37 +00008352- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008353 setting a plain string, ie don't expand to single letter identifiers.
8354
Raymond Hettinger13936692007-04-11 18:40:58 +00008355- Request #1191699: Slices can now be pickled.
8356
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008357- Request #1193128: str.translate() now allows a None argument for
8358 translations that only remove characters without re-mapping the
8359 remaining characters.
8360
Georg Brandl5cb76c12007-03-21 09:00:39 +00008361- Patch #1682205: a TypeError while unpacking an iterable is no longer
8362 masked by a generic one with the message "unpack non-sequence".
8363
Neal Norwitzaa754b72007-03-21 06:39:48 +00008364- Remove unused file Python/fmod.c.
8365
Guido van Rossum143b5642007-03-23 04:58:42 +00008366- Bug #1683368: The object.__init__() and object.__new__() methods are
8367 now stricter in rejecting excess arguments. The only time when
8368 either allows excess arguments is when it is not overridden and the
8369 other one is. For backwards compatibility, when both are
8370 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008371 warning later). Also, type.__init__() insists on the same signature
8372 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008373
Georg Brandl3ee81df2008-05-17 18:14:43 +00008374- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8375 object to complex using its __complex__() method before falling back
8376 to the __float__() method. Therefore, the functions in the cmath
8377 module now can operate on objects that define a __complex__()
8378 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Patch #1623563: allow __class__ assignment for classes with
8381 __slots__. The old and the new class are still required to have the
8382 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008383
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00008387- Patch #1462488: Python no longer segfaults when
8388 ``object.__reduce_ex__()`` is called with an object that is faking
8389 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008390
Georg Brandl3ee81df2008-05-17 18:14:43 +00008391- Patch #1680015: Don't modify __slots__ tuple if it contains an

8395
Georg Brandl7b9c5552007-03-12 14:30:05 +00008396- Bug #1678647: write a newline after printing an exception in any
8397 case, even when converting the value to a string failed.
8398
Georg Brandl871f1bc2007-03-12 13:17:36 +00008399- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008400 its argument, if it exists. If not, it will work like before. This
8401 allows customizing the output of dir() in the presence of a
8402 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008403
Collin Winter276887b2007-03-12 16:11:39 +00008404- Patch #922167: Python no longer segfaults when faced with infinitely
8405 self-recursive reload() calls (as reported by bug #742342).
8406
Georg Brandl3ee81df2008-05-17 18:14:43 +00008407- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008410- Patch #1491866: change the complex() constructor to allow
8411 parthensized forms. This means complex(repr(x)) now works instead of
8412 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008413
Georg Brandlaa2321b2007-03-07 00:40:28 +00008414- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008415 makes the filenames the warning module prints much more sensible
8416 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008417
Georg Brandl49aafc92007-03-07 00:34:46 +00008418- Variant of patch #697613: don't exit the interpreter on a SystemExit
8419 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008420 variable is given, but break into the interactive interpreter just
8421 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Bug #1674503: close the file opened by execfile() in an error
8427 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008428

8917 log file rotation using e.g. newsyslog or logrotate. This handler is
8918 only useful in Unix/Linux environments.
8919
Georg Brandlfb4b3b72007-04-24 15:27:13 +00008920- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
8921 (as opposed to the command line) will now write file names ending in
8922 ".cpp" too.
8923
Facundo Batistad918a652007-04-24 13:54:38 +00008924- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008925 the client's request was successfully received, understood, and
8926 accepted. Now in these cases no error is raised in urllib (issue
8927 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008928

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008935- Added a timeout parameter to the constructor of other protocols
8936 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8937 work started with create_connection() and timeout in httplib, and
8938 closes patch #723312.
8939
Vinay Sajip8549ce32007-05-06 17:53:37 +00008940- Patch #1676823: Added create_connection() to socket.py, which may be
8941 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008942 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008943
Martin v. Löwis0af33882007-03-23 13:27:15 +00008944- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8956 GNOME or KDE browser, depending on whether there is a session of one
8957 of those present. Also, it tries the Windows default browser before
8958 trying Mozilla variants.

8964
Georg Brandlf66b6032007-03-14 08:27:52 +00008965- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008966 AttributeError instead of an IOError when the server's response
8967 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008968
Georg Brandl3ee81df2008-05-17 18:14:43 +00008969- Patch #957650: "%var%" environment variable references are now
8970 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008972
Georg Brandl3ee81df2008-05-17 18:14:43 +00008973- Patch #1429539: pdb now correctly initializes the __main__ module
8974 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008975 correctly now.
8976
Georg Brandlbad6f192007-03-13 21:32:56 +00008977- The nonobvious commands.getstatus() function is now deprecated.

8983
Georg Brandl3ee81df2008-05-17 18:14:43 +00008984- Patch #1530482: add pydoc.render_doc() which returns the
8985 documentation for a thing instead of paging it to stdout, which
8986 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008987
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988- Patch #1533909: the timeit module now accepts callables in addition

8994 parameter which can be set to False to prevent the default
8995 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008996
Georg Brandl9e6b4702007-03-13 18:15:41 +00008997- Patch #1581073: add a flag to textwrap that prevents the dropping of
8998 whitespace while wrapping.
8999
Georg Brandl92a6bae2007-03-13 17:43:32 +00009000- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009001 are set for invalid interpolation sequences that would lead to
9002 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009003

Collin Winter22c42ba2007-03-10 02:51:26 +00009037

9045 returned string up to the first NUL character.
9046

9056
Georg Brandl3ee81df2008-05-17 18:14:43 +00009057- unittest now verifies more of its assumptions. In particular,
9058 TestCase and TestSuite subclasses (not instances) are no longer
9059 accepted in TestSuite.addTest(). This should cause no
9060 incompatibility since it never made sense with ordinary subclasses
9061 -- the failure just occurred later, with a more cumbersome
9062 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00009063

9071 given a unicode argument and os.listdir() returns unicode filenames.
9072
Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- Patch #1673619: setup.py identifies extension modules it doesn't
9074 know how to build and those it knows how to build but that fail to
9075 build.

9427 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009444- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009445 time so that opening a database previously created with the DB_DUP
9446 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9447 opens. Specifically: dictionary assignment to a DB object will
9448 replace all values for a given key when the database allows
9449 duplicate values. DB users should use DB.put(k, v) when they want
9450 to store duplicates; not DB[k] = v.

9457 characters with ASCII value less than 32. Also, it correctly quotes
9458 dots only if they occur on a single line, as opposed to the previous
9459 behavior of quoting dots if they are the second character of any
9460 line.
