1133
1134- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1135 and later systems as is currently done for Python 3.x installers.
1136 For 2.7.7 only, we will provide three installers:
1137 the legacy deprecated 10.3+ 32-bit-only format;
1138 the newer 10.5+ 32-bit-only format;
1139 and the unchanged 10.6+ 64-/32-bit format.
1140 Although binary installers will no longer be available from
1141 python.org as of 2.7.8, it will still be possible to build from
1142 source on 10.3.9 and 10.4 systems if necessary.
1143 See Mac/BuildScript/README.txt for more information.

2525 32-bit-only installer Pythons on systems with Xcode 4 (currently
2526 OS X 10.8, 10.7, and optionally 10.6).
2527 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2528 * Since Xcode 4 removes ppc support, extension module builds now
2529 check for ppc compiler support and by default remove ppc and
2530 ppc64 archs when they are not available.
2531 * Extension module builds now revert to using system installed
2532 headers and libs (/usr and /System/Library) if the SDK used
2533 to build the interpreter is not installed or has moved.
2534 * Try to avoid building extension modules with deprecated
2535 and problematic Apple llvm-gcc compiler. If original compiler
2536 is not available, use clang instead by default.

2983 64-bit/32-bit Pythons. If the user does not explicitly override
2984 the default C compiler by setting the CC environment variable,
2985 Distutils will now attempt to compile extension modules with clang
2986 if gcc-4.2 is required but not found. Also as a convenience, if
2987 the user does explicitly set CC, substitute its value as the default
2988 compiler in the Distutils LDSHARED configuration variable for OS X.
2989 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2990 SDK, neither of which are available in Xcode 4. This change does not
2991 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003241- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3242 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3243 interpreter process. This could cause failures in non-Distutils subprocesses
3244 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003245 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003246 deployment target only in the environment of each build subprocess. It is
3247 still possible to globally override the default by setting

Barry Warsawc5643282011-07-19 17:06:30 -04003278- sys.setcheckinterval() now updates the current ticker count as well as
3279 updating the check interval, so if the user decreases the check interval,
3280 the ticker doesn't have to wind down to zero from the old starting point
3281 before the new interval takes effect. And if the user increases the
3282 interval, it makes sure the new limit takes effect right away rather have an
3283 early task switch before recognizing the new interval.

4281 This prevents user-created self-referencing ordered dictionaries from
4282 becoming permanently uncollectable GC garbage. The downside is that
4283 removing __del__ means that the internal doubly-linked list has to wait for
4284 GC collection rather than freeing memory immediately when the refcnt drops
4285 to zero.

4332
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004333- Issue #9617: Signals received during a low-level write operation aren't

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004743- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4744 start byte and the continuation byte(s) are now considered invalid, instead
4745 of the number of bytes specified by the start byte.
4746 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4747 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4748 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4749 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004751- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004752 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4753 arises from the "Overriding __eq__ blocks inheritance ..." warning
4754 when turned into an exception: in this case the exception simply
4755 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004756
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004757- Issue #8748: Fix two issues with comparisons between complex and integer
4758 objects. (1) The comparison could incorrectly return True in some cases
4759 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4760 (2) The comparison raised an OverflowError for large integers, leading
4761 to unpredictable exceptions when combining integers and complex objects
4762 in sets or dicts.
4763
Mark Dickinson81336372010-05-30 12:12:25 +00004764- Issue #5211: Implicit coercion for the complex type is now completely
4765 removed. (Coercion for arithmetic operations was already removed in 2.7
4766 alpha 4, but coercion for rich comparisons was accidentally left in.)
4767
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004768- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4769 and error handler, instead of writing to the C stderr file in utf-8
4770
Georg Brandlfee0f442010-05-22 21:26:21 +00004771- Issue #7902: When using explicit relative import syntax, don't try implicit
4772 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00004773

4775 from another thread. Patch by Daniel Stutzbach.

Georg Brandlfee0f442010-05-22 21:26:21 +00004783- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
4784 of the interpreter to set sys.argv without also modifying sys.path. This
4785 helps fix `CVE-2008-5983

4902 non-float non-integer argument is now converted to an integer (if possible)
4903 using its __int__ method. Previously, only small arguments were treated this

5132 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00005144- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5145 with a non-empty format string. This is an effort to future-proof user
5146 code. If a derived class does not currently implement __format__ but later
5147 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005148 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005149 Python 3.3 and it will be an error in Python 3.4.

5222 Fractions instance now raise TypeError instead of returning True/False. This
5223 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5224 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005323- Issue #8300: When passing a non-integer argument to struct.pack with any
5324 integer format code, struct.pack first attempts to convert the non-integer
5325 using its __index__ method. If that method is non-existent or raises
5326 TypeError it goes on to try the __int__ method, as described below.
5327
Georg Brandlba83f822010-03-14 09:50:54 +00005328- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5329 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5330 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005331 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5332 inconsistent: __int__ was used for some integer codes but not for others, and
5333 the set of integer codes for which it was used differed between native packing
5334 and standard packing.)

5587 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5588 returning NULL. The macro now returns a statically allocated empty string
5589 instead.

5599 strings,
5600 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5601 numeric strings corresponding to subnormal values,
5602 (3) a memory leak for some values large enough to cause overflow, and
5603 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005634- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005635 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005636 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005641- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005642 file position when calling `truncate()`. It would previously change the file
5643 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005644 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5645

5647 class used to represent files stored inside an archive. The new
5648 implementation is significantly faster and can be wrapped in a
5649 ``io.BufferedReader`` object for more speedups. It also solves an issue
5650 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005661- Issue #7748: Since unicode values are supported for some metadata options in
5662 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5663 encoded string for them. This ensures that the upload and register commands
5664 send the correct values to PyPI without any error.

5739-----------------
5740
Georg Brandlba83f822010-03-14 09:50:54 +00005741- The ``__complex__()`` method is now looked up on the class of instances to
5742 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005743
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005744- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5745 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5746
Mark Dickinson1b34d252010-01-01 17:27:30 +00005747- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005748 DeprecationWarning when passed a float argument where an integer was expected.
5749 These functions and methods now raise TypeError instead. The majority of the
5750 effects of this change are in the extension modules, but some core functions
5751 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5752 and many unicode/str methods.

5764
Georg Brandlba83f822010-03-14 09:50:54 +00005765- Issue #1811: Improve accuracy and cross-platform consistency for true division
5766 of integers: the result of a/b is now correctly rounded for ints a and b (at
5767 least on IEEE 754 platforms), and in particular does not depend on the
5768 internal representation of a long.

5776
Georg Brandlba83f822010-03-14 09:50:54 +00005777 These executables now work properly with the arch(1) command: ``arch -ppc
5778 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005934- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5935 decimal string that's guaranteed to round back to x under correct rounding
5936 (with round-half-to-even rounding mode). Previously it gave a string based on
5937 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5938 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5939 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005941- Issue #7117: On almost all platforms: float-to-string and string-to-float
5942 conversions within Python are now correctly rounded. Places these conversions
5943 occur include: str for floats and complex numbers; the float and complex
5944 constructors; old-style and new-style numeric formatting; serialization and
5945 deserialization of floats and complex numbers using marshal, pickle and json;
5946 parsing of float and imaginary literals in Python code; Decimal-to-float
5947 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005948
Georg Brandlba83f822010-03-14 09:50:54 +00005949 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5950 providing correctly-rounded strtod and dtoa C functions. This code is
5951 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5952 the C compiler. There may be a small number of platforms on which correct
5953 operation of this code cannot be guaranteed, so the code is not used: notably,
5954 this applies to platforms where the C double format is not IEEE 754 binary64,
5955 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5956 and Python's configure script is unable to determine how to change the FPU
5957 precision. On these platforms conversions use the platform strtod and dtoa,
5958 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005960- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5961 uses the correctly-rounded string <-> float conversions described above (when
5962 available), and so produces correctly rounded results that will display nicely
5963 under the float repr. There are two related small changes: (1) round now
5964 accepts any class with an ``__index__()`` method for its second argument (but
5965 no longer accepts floats for the second argument), and (2) an excessively
5966 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5967 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007774- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7776 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7777 ``printf`` function, whereas PyString_FromFormat has an independent
7778 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007782- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7783 error.
7784
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007785- Issue #3777: long() applied to a float object now always return a long
7786 object; previously an int would be returned for small values. the __long__
7787 method is allowed to return either an int or a long, but the behaviour of
7788 float objects should not change to respect backward compatibility.
7789
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007790- Issue #3751: str.rpartition would perform a left-partition when called with
7791 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007795- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007796 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007797 was correctly parsed but parsing of subsequent arguments failed.
7798
Vinay Sajip35e3b032008-09-01 14:33:59 +00007799- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007800 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7801 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7802 when given a tuple of classes as second argument, were looking up
7803 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7804 type object.
7805
Neal Norwitz18aa3882008-08-24 05:04:52 +00007806- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007875 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7876 for catch_warnings() also led to an improvement in the raising of a
7877 DeprecationWarning related to warnings.warn_explicit().
7878

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007902- Issue #2975: When compiling several extension modules with Visual Studio 2008
7903 from the same python interpreter, some environment variables would grow
7904 without limit.
7905
Benjamin Peterson37346b22008-08-23 20:27:43 +00007906- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007943What's New in Python 2.6 beta 3?
7944================================
7945
Barry Warsaw07a4a382008-08-21 01:15:08 +00007946*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007947
7948Core and Builtins
7949-----------------
7950
Guido van Rossumf8402962008-08-20 15:01:50 +00007951- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7952 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7953 extensions do not automatically benefit from the class attribute
7954 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7955 to their tp_flags field if they care. This is a backwards
7956 compatibility feature; in 3.0, all types will use the cache by
7957 default.
7958
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007959- Keyword arguments can now follow starred arguments. (``f(a, *args,
7960 keyword=23)`` is now valid syntax.)
7961
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007962- ctypes function pointers that are COM methods have a boolean True
7963 value again.
7964
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007965- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7966 by denying s# to parse objects that have a releasebuffer procedure,
7967 and introducing s*.
7968
Georg Brandl1e13ea92008-08-11 09:07:59 +00007969- Issue #3537: Fix an assertion failure when an empty but presized dict
7970 object was stored in the freelist.
7971
Mark Dickinsonb6467572008-08-04 21:30:09 +00007972- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7973 ValueError consistently across platforms.
7974
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007975- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7976 (64bit Unix, for example), unichr() would truncate its argument and return
7977 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7978
Neal Norwitze7d8be82008-07-31 17:17:14 +00007979- Apply security patches from Apple.
7980
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007981- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7982 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7983
Antoine Pitrou92f82162008-07-25 22:22:08 +00007984- Issue #1819: function calls with several named parameters are now on
7985 average 35% faster (as measured by pybench).
7986
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007987- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7988 the python debugger steps into a class statement: the free variables (local
7989 variables defined in an outer scope) would be deleted from the outer scope.
7990
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007991- Issue #2620: Overflow checking when allocating or reallocating memory
7992 was not always being done properly in some python types and extension
7993 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7994 all been updated to perform better checks and places in the code that
7995 would previously leak memory on the error path when such an allocation
7996 failed have been fixed.

7999-------
8000
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008001- Issue #3612: Added some missing basic types in ctypes.wintypes.
8002
Benjamin Petersone977ad42008-08-20 01:42:01 +00008003- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8004 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8005
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008006- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8007 version reported by these tools does not necessarily follow the python
8008 version numbering scheme, so the module is less strict when parsing it.
8009
Nick Coghlanf70385a2008-08-18 12:42:46 +00008010- Issue #2235: Added Py3k warnings for types which will become unhashable
8011 under the stricter __hash__ inheritance rules in 3.0. Several types
8012 which did not meet the rules for hash invariants and were already
8013 unhashable in 3.0 have now been explicitly flagged as unhashable in
8014 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8015 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8016
Brett Cannon88f801d2008-08-18 00:46:22 +00008017- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8018 imported into the module but exposed as part of the module's API.
8019
Brett Cannon7b96f072008-08-18 00:41:11 +00008020- Remove an unneeded import of abc.ABCMeta from 'inspect'.

8025
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008026- Issue #3575: Incremental decoder's decode function now takes bytearray
8027 by using 's*' instead of 't#'.
8028
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008029- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008030 fails unicode conversion on 2nd parameter. (windows only)
8031
Georg Brandl222e2082010-08-01 22:27:39 +00008032- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008033 in a redirect.
8034
Brett Cannonabe423e2008-08-16 21:47:07 +00008035- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008036 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008037
Facundo Batistaeb90b782008-08-16 14:44:07 +00008038- Issue #2776: fixed small issue when handling an URL with double slash
8039 after a 302 response in the case of not going through a proxy.
8040
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008041- Issue #2676: in the email package, content-type parsing was hanging on
8042 pathological input because of quadratic or exponential behaviour of a
8043 regular expression.
8044
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008045- Issue #3476: binary buffered reading through the new "io" library is now
8046 thread-safe.
8047
Brett Cannonbf3157b2008-08-14 05:00:03 +00008048- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8049 since mimetools itself is deprecated. Because modules are cached, all
8050 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8051
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008052- Issue #3134: shutil referenced undefined WindowsError symbol.
8053
Robert Schuppenies14646332008-08-10 11:01:53 +00008054- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8055 menu entries were not deleted.
8056
Brett Cannon83e81842008-08-09 23:30:55 +00008057- Copied the implementation of reduce() to _functools.reduce() to have a
8058 version that did not raise a DeprecationWarning under -3.
8059
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008060- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8061 a MemoryError rather than silently stop the iteration.
8062
Guido van Rossum59ce9012008-08-09 14:55:34 +00008063- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8064 to _sre.compile() will now be rejected. This should not affect anybody
8065 since the re.compile() function never generates invalid re-bytecode.

8143-----------------
8144
Georg Brandl3e483f62008-07-16 22:57:41 +00008145- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8146 its methods now allow for items objects that can be converted to
8147 an integer using operator.index().
8148
Mark Dickinson64b7e502008-07-16 09:40:03 +00008149- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8150 produced a ValueError instead of giving the correct float.
8151
Eric Smitha5fa5a22008-07-16 00:11:49 +00008152- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8153 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8154
Mark Dickinson7103aa42008-07-15 19:08:33 +00008155- Issue #3008: the float type has a new instance method 'float.hex'
8156 and a new class method 'float.fromhex' to convert floating-point
8157 numbers to and from hexadecimal strings, respectively.
8158
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008159- Issue #2235: __hash__ is once again inherited by default. To allow
8160 collections.Hashable to remain meaningful in the presence of the
8161 default hash implementation (object.__hash__), it is now possible
8162 to explicit block inheritance of hash by setting __hash__=None at
8163 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8164 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00008166- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8167 the parent module cannot be found while performing an absolute import.
8168 This means that an incorrectly defined __package__ attribute will
8169 now only prevent relative imports in that module rather than causing
8170 all imports from that module to fail.
8171
Nick Coghlan14ff9942008-07-08 14:21:42 +00008172- Issue #2517: Allow unicode messages in Exceptions again by correctly

8182 another thread's dictionary.
8183
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008184- Issue #3004: Minor change to slice.indices(): the start and stop
8185 arguments are now treated identically, making the behaviour easier
8186 to describe and understand. For example, slice(None, -10,
8187 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8188 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8189 10, -1).

8232 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008233 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008234 content-length. The problem had been corrected in the 2.4 branch, but never

8636
Brett Cannonb61d8012008-05-11 23:39:04 +00008637- ``Lib/lib-old`` is now added to sys.path.
8638
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008639- On MacOS X it is now possible to install the framework in 64-bit
8640 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008641 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008642
8643 This is controlled by the configure argument ``--with-universal-archs``:
8644
8645 - ``--with-universal-archs=all``: install 4-way universal
8646
8647 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8648
8649 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8650
8651 This option should be used in combination with ``--enable-universalsdk=``.
8652
8653 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00008661
8662- The PyString functions have been renamed to PyBytes. A batch of
8663 defines were added so that the linker still sees the original
8664 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008702- Issue #1631171: Re-implement the 'warnings' module in C (the
8703 original Python code has been kept as backup). This will allow for
8704 using the 'warning's machinery in such places as the parser where
8705 use of pure Python code is not possible. Both the ``showarning()``
8706 and ``formatwarning()`` gain an optional 'line' argument which is
8707 not called by default for backwards-compatibility reasons. Setting
8708 ``warnings.showwarning()`` to an implementation that lacks support
8709 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008751- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008752 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008772- Issue #2550: The approach used by client/server code for obtaining
8773 ports to listen on in network-oriented tests has been refined in an
8774 effort to facilitate running multiple instances of the entire
8775 regression test suite in parallel without issue.
8776 test_support.bind_port() has been fixed such that it will always
8777 return a unique port -- which wasn't always the case with the
8778 previous implementation, especially if socket options had been set
8779 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8780 new implementation of bind_port() will actually raise an exception
8781 if it is passed an AF_INET/SOCK_STREAM socket with either the
8782 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8783 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8784 the socket it's been passed. This currently only applies to
8785 Windows. This option prevents any other sockets from binding to the
8786 host/port we've bound to, thus removing the possibility of the
8787 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8788 when a second SOCK_STREAM socket binds and accepts to a host/port
8789 that's already been bound by another socket. The optional preferred
8790 port parameter to bind_port() has been removed. Under no
8791 circumstances should tests be hard coding ports!
8792
8793 test_support.find_unused_port() has also been introduced, which will
8794 pass a temporary socket object to bind_port() in order to obtain an
8795 unused port. The temporary socket object is then closed and
8796 deleted, and the port is returned. This method should only be used
8797 for obtaining an unused port in order to pass to an external program
8798 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8799 a parameter to a server-oriented class that doesn't give you direct
8800 access to the underlying socket used.
8801
8802 Finally, test_support.HOST has been introduced, which should be used
8803 for the host argument of any relevant socket calls (i.e. bind and
8804 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008805
8806 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008807 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008808 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8809 test_asynchat and test_socket_ssl.
8810
Georg Brandl3ee81df2008-05-17 18:14:43 +00008811 It is now possible for multiple instances of the regression test
8812 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009091- Added the future_builtins module, which contains hex() and oct().
9092 These are the PEP 3127 version of these functions, designed to be
9093 compatible with the hex() and oct() builtins from Python 3.0. They
9094 differ slightly in their output formats from the existing, unchanged
9095 Python 2.6 builtins. The expected usage of the future_builtins
9096 module is:
9097 from future_builtins import hex, oct
9098
Eric Smith7ef40bf2008-02-20 23:34:22 +00009099- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9100 exponents for exponents with absolute value < 100. Follows C99
9101 standard. This is a change on Windows, which would use 3 digits.
9102 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9103 so that any alterations it does to the resulting string will be
9104 available in stringlib/formatter.h (for float.__format__).
9105
Eric Smith5a3c1352008-02-19 13:21:56 +00009106- Implemented PEP 3101, Advanced String Formatting. This adds a new
9107 builtin format(); a format() method for str and unicode; a
9108 __format__() method to object, str, unicode, int, long, float, and
9109 datetime; the class string.Formatter; and the C API
9110 PyObject_Format().
9111
Georg Brandl3ee81df2008-05-17 18:14:43 +00009112- Fixed several potential crashes, all caused by specially crafted
9113 __del__ methods exploiting objects in temporarily inconsistent
9114 state.

9125 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009126
Georg Brandl3ee81df2008-05-17 18:14:43 +00009127- Issue #2045: Fix an infinite recursion triggered when printing a
9128 subclass of collections.defaultdict, if its default_factory is set
9129 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009130
Christian Heimesf75dbef2008-02-08 00:11:31 +00009131- Fixed a minor memory leak in dictobject.c. The content of the free
9132 list was not freed on interpreter shutdown.
9133
Georg Brandl21e99f42010-03-07 15:23:59 +00009134- Limit free list of method and built-in function objects to 256

9138 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009139 to compact the internal free lists of pre-allocted ints and floats.
9140
Georg Brandl3ee81df2008-05-17 18:14:43 +00009141- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9142 calls. Python expected the return type int but the fork familie
9143 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009151- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9152 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00009153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9155 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009156
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Patch #1473257: generator objects gain a gi_code attribute. This is
9158 the same object as the func_code attribute of the function that
9159 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009160
Georg Brandl3ee81df2008-05-17 18:14:43 +00009161- Issue #1920: "while 0" statements were completely removed by the
9162 compiler, even in the presence of an "else" clause, which is
9163 supposed to be run when the condition is false. Now the compiler
9164 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009165
Guido van Rossumeead05f2008-01-24 18:21:02 +00009166- A few crashers fixed: weakref_in_del.py (issue #1377858);
9167 loosing_dict_ref.py (issue #1303614, test67.py);
9168 borrowed_ref_[34].py (not in tracker).
9169
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009170- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009171 suppressed while an extension is loaded by calling SetErrorMode in
9172 dynload_win.c. The error is still reported properly.
9173
Georg Brandl3ee81df2008-05-17 18:14:43 +00009174- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009175 several extension methods and modules do not work without unicode
9176 support.
9177
Georg Brandl26543b12008-01-21 18:36:51 +00009178- Issue #1882: when compiling code from a string, encoding cookies in the
9179 second line of code were not always recognized correctly.
9180
Georg Brandl14404b62008-01-19 19:27:05 +00009181- Issue #1679: "0x" was taken as a valid integer literal.
9182
Georg Brandl6caad7d2008-01-26 14:19:22 +00009183- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009184 added.
9185
Christian Heimesc94e2b52008-01-14 04:13:37 +00009186- sys.float_info / PyFloat_GetInfo: The floating point information
9187 object was converted from a dict to a specialized structseq object.
9188
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189- Patch #1816: Added sys.flags structseq. It exposes the status of
9190 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009191
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192- Objects/structseq.c: Implemented new structseq representation. The
9193 patch makes structseqs (e.g. the return value of os.stat) more
9194 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009195
Georg Brandl3ee81df2008-05-17 18:14:43 +00009196- Patch #1700288: added a type attribute cache that caches method
9197 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009198
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009199- Bug #1776: __import__() no longer accepts filenames on any platform.
9200 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009201
Georg Brandlaed6c662008-01-07 17:25:53 +00009202- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9203
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9205 envvar and sys.dont_write_bytecode attribute. All these can be set
9206 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009207
Georg Brandl3ee81df2008-05-17 18:14:43 +00009208- Improve some exception messages when Windows fails to load an
9209 extension module. Now we get for example '%1 is not a valid Win32
9210 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009211
Georg Brandl3ee81df2008-05-17 18:14:43 +00009212- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009214- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9215 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009216
Christian Heimes0a8143f2007-12-18 23:22:54 +00009217- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009218 and INF. float("nan"), float("inf") and float("-inf") now work on
9219 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009220
Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- Compiler now generates simpler and faster code for dictionary
9222 literals. The oparg for BUILD_MAP now indicates an estimated
9223 dictionary size. There is a new opcode, STORE_MAP, for adding
9224 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009225
Georg Brandl3ee81df2008-05-17 18:14:43 +00009226- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009228- Issue #1620: New property decorator syntax was modifying the
9229 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00009230
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231- Issue #1538: Avoid copying string in split/rsplit if the split char
9232 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009233
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009234- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009235 SystemError.
9236
Nick Coghlanef01d822007-12-03 12:55:17 +00009237- PEP 366: Allow explicit relative imports when executing modules
9238 inside packages with the -m switch via a new module level
9239 __package__ attribute.
9240

9242 running, and if the deallocation of its frames somehow calls the
9243 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009244

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009248 attribute of an empty cell object.
9249
Georg Brandl3ee81df2008-05-17 18:14:43 +00009250- Issue #1460: The utf-7 incremental decoder did not accept truncated
9251 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009252
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253- Patch #1739468: Directories and zipfiles containing a __main__.py
9254 file can now be directly executed by passing their name to the
9255 interpreter. The directory/zipfile is automatically inserted as the
9256 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009257
Georg Brandl3ee81df2008-05-17 18:14:43 +00009258- Issue #1265: Fix a problem with sys.settrace, if the tracing
9259 function uses a generator expression when at the same time the
9260 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009261
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009262- sets and frozensets now have an isdisjoint() method.
9263
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009264- optimize the performance of builtin.sum().
9265
Neal Norwitz44f326e2007-10-05 05:29:17 +00009266- Fix warnings found by the new version of the Coverity checker.
9267
Georg Brandl21e99f42010-03-07 15:23:59 +00009268- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009269 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9270 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009271
Georg Brandl3ee81df2008-05-17 18:14:43 +00009272- Issue #1686386: Tuple's tp_repr did not take into account the
9273 possibility of having a self-referential tuple, which is possible
9274 from C code. Nor did object's tp_str consider that a type's tp_str
9275 could do something that could lead to an inifinite recursion.
9276 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9277 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009278
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279- Issue #1164: It was possible to trigger deadlock when using the
9280 'print' statement to write to a file since the GIL was not released
9281 as needed. Now PyObject_Print() does the right thing along with
9282 various tp_print implementations of the built-in types and those in
9283 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009284
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285- Issue #1147: Exceptions were directly allowing string exceptions in
9286 their throw() method even though string exceptions no longer
9287 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009288
Georg Brandl3ee81df2008-05-17 18:14:43 +00009289- Issue #1096: Prevent a segfault from getting the repr of a very
9290 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009291
Brett Cannon1e534b52007-09-07 04:18:30 +00009292- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009293 PyObject_Call() never calling back out to Python code to trigger
9294 recursion depth updates/checks. Required the creation of a static
9295 RuntimeError instance in case normalizing an exception put the
9296 recursion check value past its limit. Fixes crashers
9297 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009298
Georg Brandl3ee81df2008-05-17 18:14:43 +00009299- Patch #1031213: Decode source line in SyntaxErrors back to its
9300 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00009302- Patch #1673759: add a missing overflow check when formatting floats
9303 with %G.
9304
Georg Brandl3ee81df2008-05-17 18:14:43 +00009305- Prevent expandtabs() on string and unicode objects from causing a
9306 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00009307

Georg Brandla5ea6892007-06-01 11:33:33 +00009311
Neal Norwitz0ac60192007-05-27 04:08:54 +00009312- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009313 __*__ attributes. (Some already existed, e.g., __doc__ and
9314 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009315
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009316- Add -3 option to the interpreter to warn about features that are
9317 deprecated and will be changed/removed in Python 3.0.
9318
Georg Brandl2134e752007-05-21 20:34:16 +00009319- Patch #1686487: you can now pass any mapping after '**' in function
9320 calls.
9321
Collin Winter62903052007-05-18 23:11:24 +00009322- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009323 "except E as target:". This is to provide forwards compatibility
9324 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009325
Brett Cannon229cee22007-05-05 01:34:02 +00009326- Deprecate BaseException.message as per PEP 352.
9327
Georg Brandl3ee81df2008-05-17 18:14:43 +00009328- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009329 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009330
Vinay Sajip8549ce32007-05-06 17:53:37 +00009331- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009332 setting a plain string, ie don't expand to single letter identifiers.
9333
Raymond Hettinger13936692007-04-11 18:40:58 +00009334- Request #1191699: Slices can now be pickled.
9335
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009336- Request #1193128: str.translate() now allows a None argument for
9337 translations that only remove characters without re-mapping the
9338 remaining characters.
9339
Georg Brandl5cb76c12007-03-21 09:00:39 +00009340- Patch #1682205: a TypeError while unpacking an iterable is no longer
9341 masked by a generic one with the message "unpack non-sequence".
9342
Neal Norwitzaa754b72007-03-21 06:39:48 +00009343- Remove unused file Python/fmod.c.
9344
Guido van Rossum143b5642007-03-23 04:58:42 +00009345- Bug #1683368: The object.__init__() and object.__new__() methods are
9346 now stricter in rejecting excess arguments. The only time when
9347 either allows excess arguments is when it is not overridden and the
9348 other one is. For backwards compatibility, when both are
9349 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009350 warning later). Also, type.__init__() insists on the same signature
9351 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009352
Georg Brandl3ee81df2008-05-17 18:14:43 +00009353- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9354 object to complex using its __complex__() method before falling back
9355 to the __float__() method. Therefore, the functions in the cmath
9356 module now can operate on objects that define a __complex__()
9357 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009358
Georg Brandl3ee81df2008-05-17 18:14:43 +00009359- Patch #1623563: allow __class__ assignment for classes with
9360 __slots__. The old and the new class are still required to have the
9361 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009362
Georg Brandl3ee81df2008-05-17 18:14:43 +00009363- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00009366- Patch #1462488: Python no longer segfaults when
9367 ``object.__reduce_ex__()`` is called with an object that is faking
9368 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009369
Georg Brandl3ee81df2008-05-17 18:14:43 +00009370- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00009373- Patch #1444529: the builtin compile() now accepts keyword arguments.
9374
Georg Brandl7b9c5552007-03-12 14:30:05 +00009375- Bug #1678647: write a newline after printing an exception in any
9376 case, even when converting the value to a string failed.
9377
Georg Brandl871f1bc2007-03-12 13:17:36 +00009378- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009379 its argument, if it exists. If not, it will work like before. This
9380 allows customizing the output of dir() in the presence of a
9381 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009382
Collin Winter276887b2007-03-12 16:11:39 +00009383- Patch #922167: Python no longer segfaults when faced with infinitely
9384 self-recursive reload() calls (as reported by bug #742342).
9385
Georg Brandl3ee81df2008-05-17 18:14:43 +00009386- Patch #1675981: remove unreachable code from ``type.__new__()``
9387 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00009388
Georg Brandl3ee81df2008-05-17 18:14:43 +00009389- Patch #1491866: change the complex() constructor to allow

9901 ".cpp" too.
9902
Facundo Batistad918a652007-04-24 13:54:38 +00009903- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009904 the client's request was successfully received, understood, and
9905 accepted. Now in these cases no error is raised in urllib (issue
9906 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009907

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009914- Added a timeout parameter to the constructor of other protocols
9915 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9916 work started with create_connection() and timeout in httplib, and
9917 closes patch #723312.
9918
Vinay Sajip8549ce32007-05-06 17:53:37 +00009919- Patch #1676823: Added create_connection() to socket.py, which may be
9920 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00009922
Martin v. Löwis0af33882007-03-23 13:27:15 +00009923- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009930- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
9931 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00009932 directories.

9943
Georg Brandlf66b6032007-03-14 08:27:52 +00009944- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00009945 AttributeError instead of an IOError when the server's response
9946 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009947
Georg Brandl3ee81df2008-05-17 18:14:43 +00009948- Patch #957650: "%var%" environment variable references are now
9949 properly expanded in ntpath.expandvars(), also "~user" home
9950 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00009951
Georg Brandl3ee81df2008-05-17 18:14:43 +00009952- Patch #1429539: pdb now correctly initializes the __main__ module
9953 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009954 correctly now.
9955
Georg Brandlbad6f192007-03-13 21:32:56 +00009956- The nonobvious commands.getstatus() function is now deprecated.

9962
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963- Patch #1530482: add pydoc.render_doc() which returns the
9964 documentation for a thing instead of paging it to stdout, which
9965 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009966
Georg Brandl3ee81df2008-05-17 18:14:43 +00009967- Patch #1533909: the timeit module now accepts callables in addition

9978
Georg Brandl92a6bae2007-03-13 17:43:32 +00009979- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009980 are set for invalid interpolation sequences that would lead to
9981 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009982

Georg Brandl3ee81df2008-05-17 18:14:43 +00009997 field names in its exception message if you try to write a record
9998 with a dictionary containing fields not in the CSV field names list.

10024 returned string up to the first NUL character.
10025

10035
Georg Brandl3ee81df2008-05-17 18:14:43 +000010036- unittest now verifies more of its assumptions. In particular,
10037 TestCase and TestSuite subclasses (not instances) are no longer
10038 accepted in TestSuite.addTest(). This should cause no
10039 incompatibility since it never made sense with ordinary subclasses
10040 -- the failure just occurred later, with a more cumbersome
10041 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010424 time so that opening a database previously created with the DB_DUP
10425 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10426 opens. Specifically: dictionary assignment to a DB object will
10427 replace all values for a given key when the database allows
10428 duplicate values. DB users should use DB.put(k, v) when they want
10429 to store duplicates; not DB[k] = v.

10436 characters with ASCII value less than 32. Also, it correctly quotes
10437 dots only if they occur on a single line, as opposed to the previous
10438 behavior of quoting dots if they are the second character of any
10439 line.
