1123
1124- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1125 and later systems as is currently done for Python 3.x installers.
1126 For 2.7.7 only, we will provide three installers:
1127 the legacy deprecated 10.3+ 32-bit-only format;
1128 the newer 10.5+ 32-bit-only format;
1129 and the unchanged 10.6+ 64-/32-bit format.
1130 Although binary installers will no longer be available from
1131 python.org as of 2.7.8, it will still be possible to build from
1132 source on 10.3.9 and 10.4 systems if necessary.
1133 See Mac/BuildScript/README.txt for more information.

2515 32-bit-only installer Pythons on systems with Xcode 4 (currently
2516 OS X 10.8, 10.7, and optionally 10.6).
2517 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2518 * Since Xcode 4 removes ppc support, extension module builds now
2519 check for ppc compiler support and by default remove ppc and
2520 ppc64 archs when they are not available.
2521 * Extension module builds now revert to using system installed
2522 headers and libs (/usr and /System/Library) if the SDK used
2523 to build the interpreter is not installed or has moved.
2524 * Try to avoid building extension modules with deprecated
2525 and problematic Apple llvm-gcc compiler. If original compiler
2526 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002970- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2971 Distutils-based packages with C extension modules may fail because
2972 Apple has removed gcc-4.2, the version used to build python.org
2973 64-bit/32-bit Pythons. If the user does not explicitly override
2974 the default C compiler by setting the CC environment variable,
2975 Distutils will now attempt to compile extension modules with clang
2976 if gcc-4.2 is required but not found. Also as a convenience, if
2977 the user does explicitly set CC, substitute its value as the default
2978 compiler in the Distutils LDSHARED configuration variable for OS X.
2979 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2980 SDK, neither of which are available in Xcode 4. This change does not
2981 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003231- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3232 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3233 interpreter process. This could cause failures in non-Distutils subprocesses
3234 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003235 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003236 deployment target only in the environment of each build subprocess. It is
3237 still possible to globally override the default by setting
3238 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3239 greater or equal to the default value, the value with which the interpreter
3240 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04003268- sys.setcheckinterval() now updates the current ticker count as well as
3269 updating the check interval, so if the user decreases the check interval,
3270 the ticker doesn't have to wind down to zero from the old starting point
3271 before the new interval takes effect. And if the user increases the
3272 interval, it makes sure the new limit takes effect right away rather have an
3273 early task switch before recognizing the new interval.

4271 This prevents user-created self-referencing ordered dictionaries from
4272 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004733- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4734 start byte and the continuation byte(s) are now considered invalid, instead
4735 of the number of bytes specified by the start byte.
4736 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4737 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4738 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4739 Previous versions returned a single u'\ufffd'.
4740
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004741- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004742 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4743 arises from the "Overriding __eq__ blocks inheritance ..." warning
4744 when turned into an exception: in this case the exception simply
4745 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004746
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004747- Issue #8748: Fix two issues with comparisons between complex and integer
4748 objects. (1) The comparison could incorrectly return True in some cases
4749 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4750 (2) The comparison raised an OverflowError for large integers, leading
4751 to unpredictable exceptions when combining integers and complex objects
4752 in sets or dicts.
4753
Mark Dickinson81336372010-05-30 12:12:25 +00004754- Issue #5211: Implicit coercion for the complex type is now completely
4755 removed. (Coercion for arithmetic operations was already removed in 2.7
4756 alpha 4, but coercion for rich comparisons was accidentally left in.)
4757
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004758- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4759 and error handler, instead of writing to the C stderr file in utf-8
4760
Georg Brandlfee0f442010-05-22 21:26:21 +00004761- Issue #7902: When using explicit relative import syntax, don't try implicit
4762 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00004763
Georg Brandlfee0f442010-05-22 21:26:21 +00004764- Issue #7079: Fix a possible crash when closing a file object while using it
4765 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00004766
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00004767- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00004768 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00004773- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
4774 of the interpreter to set sys.argv without also modifying sys.path. This
4775 helps fix `CVE-2008-5983

5122 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00005134- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5135 with a non-empty format string. This is an effort to future-proof user
5136 code. If a derived class does not currently implement __format__ but later
5137 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005138 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005139 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005189- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5190 InvalidOperation instead of returning False. (Comparisons involving a quiet
5191 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5192 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005193
Georg Brandlfee0f442010-05-22 21:26:21 +00005194- Issue #2531: Comparison operations between floats and Decimal instances now
5195 return a result based on the numeric values of the operands; previously they

Georg Brandlfee0f442010-05-22 21:26:21 +00005211- Comparisons using one of <, <=, >, >= between a complex instance and a
5212 Fractions instance now raise TypeError instead of returning True/False. This
5213 makes Fraction <=> complex comparisons consistent with int <=> complex, float

R. David Murrayf28fd242010-02-23 00:24:49 +00005534 is run with the -OO flag. Tests requiring docstrings are skipped.
5535
Georg Brandlba83f822010-03-14 09:50:54 +00005536- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is

Georg Brandlba83f822010-03-14 09:50:54 +00005576- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5577 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5578 returning NULL. The macro now returns a statically allocated empty string
5579 instead.

5589 strings,
5590 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5591 numeric strings corresponding to subnormal values,
5592 (3) a memory leak for some values large enough to cause overflow, and
5593 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005624- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005625 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005631- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005632 file position when calling `truncate()`. It would previously change the file
5633 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005634 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5635

5637 class used to represent files stored inside an archive. The new
5638 implementation is significantly faster and can be wrapped in a
5639 ``io.BufferedReader`` object for more speedups. It also solves an issue
5640 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005651- Issue #7748: Since unicode values are supported for some metadata options in
5652 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5653 encoded string for them. This ensures that the upload and register commands
5654 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005731- The ``__complex__()`` method is now looked up on the class of instances to
5732 make it consistent with other special methods.

5736
Mark Dickinson1b34d252010-01-01 17:27:30 +00005737- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005738 DeprecationWarning when passed a float argument where an integer was expected.
5739 These functions and methods now raise TypeError instead. The majority of the
5740 effects of this change are in the extension modules, but some core functions
5741 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5742 and many unicode/str methods.

5756 of integers: the result of a/b is now correctly rounded for ints a and b (at
5757 least on IEEE 754 platforms), and in particular does not depend on the
5758 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005767 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005924- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5925 decimal string that's guaranteed to round back to x under correct rounding
5926 (with round-half-to-even rounding mode). Previously it gave a string based on
5927 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5928 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5929 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005931- Issue #7117: On almost all platforms: float-to-string and string-to-float
5932 conversions within Python are now correctly rounded. Places these conversions
5933 occur include: str for floats and complex numbers; the float and complex
5934 constructors; old-style and new-style numeric formatting; serialization and
5935 deserialization of floats and complex numbers using marshal, pickle and json;
5936 parsing of float and imaginary literals in Python code; Decimal-to-float
5937 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005938
Georg Brandlba83f822010-03-14 09:50:54 +00005939 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5940 providing correctly-rounded strtod and dtoa C functions. This code is
5941 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5942 the C compiler. There may be a small number of platforms on which correct
5943 operation of this code cannot be guaranteed, so the code is not used: notably,
5944 this applies to platforms where the C double format is not IEEE 754 binary64,
5945 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5946 and Python's configure script is unable to determine how to change the FPU
5947 precision. On these platforms conversions use the platform strtod and dtoa,
5948 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005950- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5951 uses the correctly-rounded string <-> float conversions described above (when
5952 available), and so produces correctly rounded results that will display nicely
5953 under the float repr. There are two related small changes: (1) round now
5954 accepts any class with an ``__index__()`` method for its second argument (but
5955 no longer accepts floats for the second argument), and (2) an excessively
5956 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5957 raises an exception.

7564 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7565 neither __int__ nor __long__, TypeError used to be raised (with a

7766 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7767 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007785- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007786 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007787 was correctly parsed but parsing of subsequent arguments failed.
7788
Vinay Sajip35e3b032008-09-01 14:33:59 +00007789- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007790 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7791 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7792 when given a tuple of classes as second argument, were looking up
7793 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7794 type object.
7795
Neal Norwitz18aa3882008-08-24 05:04:52 +00007796- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007865 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7866 for catch_warnings() also led to an improvement in the raising of a
7867 DeprecationWarning related to warnings.warn_explicit().
7868

7894 without limit.
7895
Benjamin Peterson37346b22008-08-23 20:27:43 +00007896- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007933What's New in Python 2.6 beta 3?
7934================================
7935
Barry Warsaw07a4a382008-08-21 01:15:08 +00007936*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007937
7938Core and Builtins
7939-----------------
7940
Guido van Rossumf8402962008-08-20 15:01:50 +00007941- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7942 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7943 extensions do not automatically benefit from the class attribute
7944 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7945 to their tp_flags field if they care. This is a backwards
7946 compatibility feature; in 3.0, all types will use the cache by
7947 default.
7948
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007949- Keyword arguments can now follow starred arguments. (``f(a, *args,
7950 keyword=23)`` is now valid syntax.)
7951
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007952- ctypes function pointers that are COM methods have a boolean True
7953 value again.
7954
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007955- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7956 by denying s# to parse objects that have a releasebuffer procedure,
7957 and introducing s*.
7958
Georg Brandl1e13ea92008-08-11 09:07:59 +00007959- Issue #3537: Fix an assertion failure when an empty but presized dict
7960 object was stored in the freelist.
7961
Mark Dickinsonb6467572008-08-04 21:30:09 +00007962- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7963 ValueError consistently across platforms.
7964
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007965- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7966 (64bit Unix, for example), unichr() would truncate its argument and return
7967 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7968
Neal Norwitze7d8be82008-07-31 17:17:14 +00007969- Apply security patches from Apple.
7970
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007971- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7972 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7973
Antoine Pitrou92f82162008-07-25 22:22:08 +00007974- Issue #1819: function calls with several named parameters are now on
7975 average 35% faster (as measured by pybench).
7976
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007977- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7978 the python debugger steps into a class statement: the free variables (local
7979 variables defined in an outer scope) would be deleted from the outer scope.
7980
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007981- Issue #2620: Overflow checking when allocating or reallocating memory
7982 was not always being done properly in some python types and extension
7983 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7984 all been updated to perform better checks and places in the code that
7985 would previously leak memory on the error path when such an allocation
7986 failed have been fixed.
7987

7989-------
7990
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007991- Issue #3612: Added some missing basic types in ctypes.wintypes.
7992
Benjamin Petersone977ad42008-08-20 01:42:01 +00007993- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7994 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7995
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007996- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7997 version reported by these tools does not necessarily follow the python
7998 version numbering scheme, so the module is less strict when parsing it.
7999
Nick Coghlanf70385a2008-08-18 12:42:46 +00008000- Issue #2235: Added Py3k warnings for types which will become unhashable
8001 under the stricter __hash__ inheritance rules in 3.0. Several types
8002 which did not meet the rules for hash invariants and were already
8003 unhashable in 3.0 have now been explicitly flagged as unhashable in
8004 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8005 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8006
Brett Cannon88f801d2008-08-18 00:46:22 +00008007- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8008 imported into the module but exposed as part of the module's API.
8009
Brett Cannon7b96f072008-08-18 00:41:11 +00008010- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8011
Brett Cannon46225e72008-08-18 00:36:52 +00008012- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008014- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8015
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008016- Issue #3575: Incremental decoder's decode function now takes bytearray
8017 by using 's*' instead of 't#'.
8018
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008019- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008020 fails unicode conversion on 2nd parameter. (windows only)
8021
Georg Brandl222e2082010-08-01 22:27:39 +00008022- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008023 in a redirect.
8024
Brett Cannonabe423e2008-08-16 21:47:07 +00008025- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008026 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008027
Facundo Batistaeb90b782008-08-16 14:44:07 +00008028- Issue #2776: fixed small issue when handling an URL with double slash
8029 after a 302 response in the case of not going through a proxy.
8030
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008031- Issue #2676: in the email package, content-type parsing was hanging on
8032 pathological input because of quadratic or exponential behaviour of a
8033 regular expression.
8034
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008035- Issue #3476: binary buffered reading through the new "io" library is now
8036 thread-safe.
8037
Brett Cannonbf3157b2008-08-14 05:00:03 +00008038- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8039 since mimetools itself is deprecated. Because modules are cached, all
8040 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8041
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008042- Issue #3134: shutil referenced undefined WindowsError symbol.
8043
Robert Schuppenies14646332008-08-10 11:01:53 +00008044- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8045 menu entries were not deleted.
8046
Brett Cannon83e81842008-08-09 23:30:55 +00008047- Copied the implementation of reduce() to _functools.reduce() to have a
8048 version that did not raise a DeprecationWarning under -3.
8049
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008050- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8051 a MemoryError rather than silently stop the iteration.
8052
Guido van Rossum59ce9012008-08-09 14:55:34 +00008053- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8054 to _sre.compile() will now be rejected. This should not affect anybody
8055 since the re.compile() function never generates invalid re-bytecode.
8056
Skip Montanaroa032bf42008-08-08 22:52:51 +00008057- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8058 upon first access it can be automatically initialized from the csv file if
8059 it wasn't initialized during instantiation.
8060
Brett Cannon3aa2a492008-08-06 22:28:09 +00008061- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8062 the reload() built-in has been removed.
8063
Brett Cannon7e30b672008-08-04 21:52:25 +00008064- Changed code in the following modules/packages to remove warnings raised

8133-----------------
8134
Georg Brandl3e483f62008-07-16 22:57:41 +00008135- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8136 its methods now allow for items objects that can be converted to
8137 an integer using operator.index().
8138
Mark Dickinson64b7e502008-07-16 09:40:03 +00008139- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8140 produced a ValueError instead of giving the correct float.
8141
Eric Smitha5fa5a22008-07-16 00:11:49 +00008142- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8143 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8144
Mark Dickinson7103aa42008-07-15 19:08:33 +00008145- Issue #3008: the float type has a new instance method 'float.hex'
8146 and a new class method 'float.fromhex' to convert floating-point
8147 numbers to and from hexadecimal strings, respectively.
8148
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008149- Issue #2235: __hash__ is once again inherited by default. To allow
8150 collections.Hashable to remain meaningful in the presence of the
8151 default hash implementation (object.__hash__), it is now possible
8152 to explicit block inheritance of hash by setting __hash__=None at
8153 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8154 level.
8155
Nick Coghlanb028f502008-07-13 14:52:36 +00008156- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8157 the parent module cannot be found while performing an absolute import.
8158 This means that an incorrectly defined __package__ attribute will
8159 now only prevent relative imports in that module rather than causing
8160 all imports from that module to fail.
8161
Nick Coghlan14ff9942008-07-08 14:21:42 +00008162- Issue #2517: Allow unicode messages in Exceptions again by correctly

8172 another thread's dictionary.
8173
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008174- Issue #3004: Minor change to slice.indices(): the start and stop
8175 arguments are now treated identically, making the behaviour easier
8176 to describe and understand. For example, slice(None, -10,
8177 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8178 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8179 10, -1).

8222 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008223 wrong because the actual transmitted size could differ from the

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008240- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00008631 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008632
8633 This is controlled by the configure argument ``--with-universal-archs``:
8634
8635 - ``--with-universal-archs=all``: install 4-way universal
8636
8637 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8638
8639 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8640
8641 This option should be used in combination with ``--enable-universalsdk=``.
8642
8643 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

8647
Georg Brandl74a1dea2008-05-28 11:21:39 +00008648- Add ``PyType_Modified()`` as a public API to clear the type cache.
8649
8650- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00008651
8652- The PyString functions have been renamed to PyBytes. A batch of
8653 defines were added so that the linker still sees the original
8654 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008692- Issue #1631171: Re-implement the 'warnings' module in C (the
8693 original Python code has been kept as backup). This will allow for
8694 using the 'warning's machinery in such places as the parser where
8695 use of pure Python code is not possible. Both the ``showarning()``
8696 and ``formatwarning()`` gain an optional 'line' argument which is
8697 not called by default for backwards-compatibility reasons. Setting
8698 ``warnings.showwarning()`` to an implementation that lacks support
8699 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008741- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008742 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008762- Issue #2550: The approach used by client/server code for obtaining
8763 ports to listen on in network-oriented tests has been refined in an
8764 effort to facilitate running multiple instances of the entire
8765 regression test suite in parallel without issue.
8766 test_support.bind_port() has been fixed such that it will always
8767 return a unique port -- which wasn't always the case with the
8768 previous implementation, especially if socket options had been set
8769 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8770 new implementation of bind_port() will actually raise an exception
8771 if it is passed an AF_INET/SOCK_STREAM socket with either the
8772 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8773 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8774 the socket it's been passed. This currently only applies to
8775 Windows. This option prevents any other sockets from binding to the
8776 host/port we've bound to, thus removing the possibility of the
8777 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8778 when a second SOCK_STREAM socket binds and accepts to a host/port
8779 that's already been bound by another socket. The optional preferred
8780 port parameter to bind_port() has been removed. Under no
8781 circumstances should tests be hard coding ports!
8782
8783 test_support.find_unused_port() has also been introduced, which will
8784 pass a temporary socket object to bind_port() in order to obtain an
8785 unused port. The temporary socket object is then closed and
8786 deleted, and the port is returned. This method should only be used
8787 for obtaining an unused port in order to pass to an external program
8788 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8789 a parameter to a server-oriented class that doesn't give you direct
8790 access to the underlying socket used.
8791
8792 Finally, test_support.HOST has been introduced, which should be used
8793 for the host argument of any relevant socket calls (i.e. bind and
8794 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008795
8796 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008797 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008798 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8799 test_asynchat and test_socket_ssl.
8800
Georg Brandl3ee81df2008-05-17 18:14:43 +00008801 It is now possible for multiple instances of the regression test
8802 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009081- Added the future_builtins module, which contains hex() and oct().
9082 These are the PEP 3127 version of these functions, designed to be
9083 compatible with the hex() and oct() builtins from Python 3.0. They
9084 differ slightly in their output formats from the existing, unchanged
9085 Python 2.6 builtins. The expected usage of the future_builtins
9086 module is:
9087 from future_builtins import hex, oct
9088
Eric Smith7ef40bf2008-02-20 23:34:22 +00009089- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9090 exponents for exponents with absolute value < 100. Follows C99
9091 standard. This is a change on Windows, which would use 3 digits.
9092 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9093 so that any alterations it does to the resulting string will be
9094 available in stringlib/formatter.h (for float.__format__).
9095
Eric Smith5a3c1352008-02-19 13:21:56 +00009096- Implemented PEP 3101, Advanced String Formatting. This adds a new
9097 builtin format(); a format() method for str and unicode; a
9098 __format__() method to object, str, unicode, int, long, float, and
9099 datetime; the class string.Formatter; and the C API
9100 PyObject_Format().
9101
Georg Brandl3ee81df2008-05-17 18:14:43 +00009102- Fixed several potential crashes, all caused by specially crafted
9103 __del__ methods exploiting objects in temporarily inconsistent
9104 state.

9115 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009116
Georg Brandl3ee81df2008-05-17 18:14:43 +00009117- Issue #2045: Fix an infinite recursion triggered when printing a
9118 subclass of collections.defaultdict, if its default_factory is set
9119 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009120
Christian Heimesf75dbef2008-02-08 00:11:31 +00009121- Fixed a minor memory leak in dictobject.c. The content of the free

Georg Brandl3ee81df2008-05-17 18:14:43 +00009147- Patch #1473257: generator objects gain a gi_code attribute. This is
9148 the same object as the func_code attribute of the function that
9149 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009150
Georg Brandl3ee81df2008-05-17 18:14:43 +00009151- Issue #1920: "while 0" statements were completely removed by the
9152 compiler, even in the presence of an "else" clause, which is
9153 supposed to be run when the condition is false. Now the compiler
9154 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009155
Guido van Rossumeead05f2008-01-24 18:21:02 +00009156- A few crashers fixed: weakref_in_del.py (issue #1377858);
9157 loosing_dict_ref.py (issue #1303614, test67.py);
9158 borrowed_ref_[34].py (not in tracker).
9159
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009160- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009161 suppressed while an extension is loaded by calling SetErrorMode in
9162 dynload_win.c. The error is still reported properly.
9163
Georg Brandl3ee81df2008-05-17 18:14:43 +00009164- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009165 several extension methods and modules do not work without unicode
9166 support.
9167
Georg Brandl26543b12008-01-21 18:36:51 +00009168- Issue #1882: when compiling code from a string, encoding cookies in the
9169 second line of code were not always recognized correctly.
9170
Georg Brandl14404b62008-01-19 19:27:05 +00009171- Issue #1679: "0x" was taken as a valid integer literal.
9172
Georg Brandl6caad7d2008-01-26 14:19:22 +00009173- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009174 added.
9175
Christian Heimesc94e2b52008-01-14 04:13:37 +00009176- sys.float_info / PyFloat_GetInfo: The floating point information
9177 object was converted from a dict to a specialized structseq object.
9178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- Patch #1816: Added sys.flags structseq. It exposes the status of
9180 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009181
Georg Brandl3ee81df2008-05-17 18:14:43 +00009182- Objects/structseq.c: Implemented new structseq representation. The
9183 patch makes structseqs (e.g. the return value of os.stat) more
9184 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009185
Georg Brandl3ee81df2008-05-17 18:14:43 +00009186- Patch #1700288: added a type attribute cache that caches method
9187 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009188
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009189- Bug #1776: __import__() no longer accepts filenames on any platform.
9190 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009191
Georg Brandlaed6c662008-01-07 17:25:53 +00009192- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9193
Georg Brandl3ee81df2008-05-17 18:14:43 +00009194- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9195 envvar and sys.dont_write_bytecode attribute. All these can be set
9196 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009197
Georg Brandl3ee81df2008-05-17 18:14:43 +00009198- Improve some exception messages when Windows fails to load an
9199 extension module. Now we get for example '%1 is not a valid Win32
9200 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009201
Georg Brandl3ee81df2008-05-17 18:14:43 +00009202- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9205 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009206
Christian Heimes0a8143f2007-12-18 23:22:54 +00009207- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009208 and INF. float("nan"), float("inf") and float("-inf") now work on
9209 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009210
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Compiler now generates simpler and faster code for dictionary
9212 literals. The oparg for BUILD_MAP now indicates an estimated
9213 dictionary size. There is a new opcode, STORE_MAP, for adding
9214 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- Issue #1538: Avoid copying string in split/rsplit if the split char
9222 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009223
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009224- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009225 SystemError.
9226
Nick Coghlanef01d822007-12-03 12:55:17 +00009227- PEP 366: Allow explicit relative imports when executing modules
9228 inside packages with the -m switch via a new module level
9229 __package__ attribute.
9230
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231- Issue #1402: Fix a crash on exit, when another thread is still
9232 running, and if the deallocation of its frames somehow calls the
9233 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009234

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009238 attribute of an empty cell object.
9239
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Issue #1460: The utf-7 incremental decoder did not accept truncated
9241 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009242
Georg Brandl3ee81df2008-05-17 18:14:43 +00009243- Patch #1739468: Directories and zipfiles containing a __main__.py
9244 file can now be directly executed by passing their name to the
9245 interpreter. The directory/zipfile is automatically inserted as the
9246 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009247
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- Issue #1265: Fix a problem with sys.settrace, if the tracing
9249 function uses a generator expression when at the same time the
9250 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009251
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009252- sets and frozensets now have an isdisjoint() method.
9253
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009254- optimize the performance of builtin.sum().
9255
Neal Norwitz44f326e2007-10-05 05:29:17 +00009256- Fix warnings found by the new version of the Coverity checker.
9257
Georg Brandl21e99f42010-03-07 15:23:59 +00009258- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009259 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9260 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009261
Georg Brandl3ee81df2008-05-17 18:14:43 +00009262- Issue #1686386: Tuple's tp_repr did not take into account the
9263 possibility of having a self-referential tuple, which is possible
9264 from C code. Nor did object's tp_str consider that a type's tp_str
9265 could do something that could lead to an inifinite recursion.
9266 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9267 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009268
Georg Brandl3ee81df2008-05-17 18:14:43 +00009269- Issue #1164: It was possible to trigger deadlock when using the
9270 'print' statement to write to a file since the GIL was not released
9271 as needed. Now PyObject_Print() does the right thing along with
9272 various tp_print implementations of the built-in types and those in
9273 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009274
Georg Brandl3ee81df2008-05-17 18:14:43 +00009275- Issue #1147: Exceptions were directly allowing string exceptions in
9276 their throw() method even though string exceptions no longer
9277 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009278
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279- Issue #1096: Prevent a segfault from getting the repr of a very
9280 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009281
Brett Cannon1e534b52007-09-07 04:18:30 +00009282- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009283 PyObject_Call() never calling back out to Python code to trigger
9284 recursion depth updates/checks. Required the creation of a static
9285 RuntimeError instance in case normalizing an exception put the
9286 recursion check value past its limit. Fixes crashers
9287 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009288
Georg Brandl3ee81df2008-05-17 18:14:43 +00009289- Patch #1031213: Decode source line in SyntaxErrors back to its

9293 with %G.
9294
Georg Brandl3ee81df2008-05-17 18:14:43 +00009295- Prevent expandtabs() on string and unicode objects from causing a
9296 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00009297

Neal Norwitz0ac60192007-05-27 04:08:54 +00009302- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009303 __*__ attributes. (Some already existed, e.g., __doc__ and
9304 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009305
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009306- Add -3 option to the interpreter to warn about features that are
9307 deprecated and will be changed/removed in Python 3.0.
9308
Georg Brandl2134e752007-05-21 20:34:16 +00009309- Patch #1686487: you can now pass any mapping after '**' in function
9310 calls.
9311
Collin Winter62903052007-05-18 23:11:24 +00009312- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009313 "except E as target:". This is to provide forwards compatibility
9314 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009315
Brett Cannon229cee22007-05-05 01:34:02 +00009316- Deprecate BaseException.message as per PEP 352.
9317
Georg Brandl3ee81df2008-05-17 18:14:43 +00009318- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009319 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009320
Vinay Sajip8549ce32007-05-06 17:53:37 +00009321- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009322 setting a plain string, ie don't expand to single letter identifiers.
9323
Raymond Hettinger13936692007-04-11 18:40:58 +00009324- Request #1191699: Slices can now be pickled.
9325
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009326- Request #1193128: str.translate() now allows a None argument for
9327 translations that only remove characters without re-mapping the
9328 remaining characters.
9329
Georg Brandl5cb76c12007-03-21 09:00:39 +00009330- Patch #1682205: a TypeError while unpacking an iterable is no longer
9331 masked by a generic one with the message "unpack non-sequence".
9332
Neal Norwitzaa754b72007-03-21 06:39:48 +00009333- Remove unused file Python/fmod.c.
9334
Guido van Rossum143b5642007-03-23 04:58:42 +00009335- Bug #1683368: The object.__init__() and object.__new__() methods are
9336 now stricter in rejecting excess arguments. The only time when
9337 either allows excess arguments is when it is not overridden and the
9338 other one is. For backwards compatibility, when both are
9339 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009340 warning later). Also, type.__init__() insists on the same signature
9341 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009342
Georg Brandl3ee81df2008-05-17 18:14:43 +00009343- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9344 object to complex using its __complex__() method before falling back
9345 to the __float__() method. Therefore, the functions in the cmath
9346 module now can operate on objects that define a __complex__()
9347 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009348
Georg Brandl3ee81df2008-05-17 18:14:43 +00009349- Patch #1623563: allow __class__ assignment for classes with
9350 __slots__. The old and the new class are still required to have the
9351 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009352
Georg Brandl3ee81df2008-05-17 18:14:43 +00009353- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00009356- Patch #1462488: Python no longer segfaults when
9357 ``object.__reduce_ex__()`` is called with an object that is faking
9358 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009359
Georg Brandl3ee81df2008-05-17 18:14:43 +00009360- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00009363- Patch #1444529: the builtin compile() now accepts keyword arguments.
9364
Georg Brandl7b9c5552007-03-12 14:30:05 +00009365- Bug #1678647: write a newline after printing an exception in any
9366 case, even when converting the value to a string failed.
9367
Georg Brandl871f1bc2007-03-12 13:17:36 +00009368- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009369 its argument, if it exists. If not, it will work like before. This
9370 allows customizing the output of dir() in the presence of a
9371 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009372
Collin Winter276887b2007-03-12 16:11:39 +00009373- Patch #922167: Python no longer segfaults when faced with infinitely
9374 self-recursive reload() calls (as reported by bug #742342).
9375
Georg Brandl3ee81df2008-05-17 18:14:43 +00009376- Patch #1675981: remove unreachable code from ``type.__new__()``
9377 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00009378
Georg Brandl3ee81df2008-05-17 18:14:43 +00009379- Patch #1491866: change the complex() constructor to allow
9380 parthensized forms. This means complex(repr(x)) now works instead of
9381 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009382
Georg Brandlaa2321b2007-03-07 00:40:28 +00009383- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009384 makes the filenames the warning module prints much more sensible

Facundo Batistad918a652007-04-24 13:54:38 +00009893- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009894 the client's request was successfully received, understood, and
9895 accepted. Now in these cases no error is raised in urllib (issue
9896 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009897

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009904- Added a timeout parameter to the constructor of other protocols
9905 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9906 work started with create_connection() and timeout in httplib, and
9907 closes patch #723312.
9908
Vinay Sajip8549ce32007-05-06 17:53:37 +00009909- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00009935 AttributeError instead of an IOError when the server's response
9936 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009937
Georg Brandl3ee81df2008-05-17 18:14:43 +00009938- Patch #957650: "%var%" environment variable references are now
9939 properly expanded in ntpath.expandvars(), also "~user" home

9943 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009944 correctly now.
9945

9952
Georg Brandl3ee81df2008-05-17 18:14:43 +00009953- Patch #1530482: add pydoc.render_doc() which returns the
9954 documentation for a thing instead of paging it to stdout, which
9955 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009956
Georg Brandl3ee81df2008-05-17 18:14:43 +00009957- Patch #1533909: the timeit module now accepts callables in addition

9968
Georg Brandl92a6bae2007-03-13 17:43:32 +00009969- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009970 are set for invalid interpolation sequences that would lead to
9971 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009972

10014 returned string up to the first NUL character.

10025
Georg Brandl3ee81df2008-05-17 18:14:43 +000010026- unittest now verifies more of its assumptions. In particular,
10027 TestCase and TestSuite subclasses (not instances) are no longer
10028 accepted in TestSuite.addTest(). This should cause no

10030 -- the failure just occurred later, with a more cumbersome
10031 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010413- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010414 time so that opening a database previously created with the DB_DUP
10415 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10416 opens. Specifically: dictionary assignment to a DB object will
10417 replace all values for a given key when the database allows
10418 duplicate values. DB users should use DB.put(k, v) when they want
10419 to store duplicates; not DB[k] = v.

10426 characters with ASCII value less than 32. Also, it correctly quotes
10427 dots only if they occur on a single line, as opposed to the previous
10428 behavior of quoting dots if they are the second character of any
10429 line.
