48 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily87e82bb2011-06-28 19:52:59 -0700298- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
299 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
300 interpreter process. This could cause failures in non-Distutils subprocesses
301 and was unreliable since tests or user programs could modify the interpreter
302 environment after Distutils set it. Instead, have Distutils set the the
303 deployment target only in the environment of each build subprocess. It is
304 still possible to globally override the default by setting
305 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
306 greater or equal to the default value, the value with which the interpreter
307 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001245- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1246 This prevents user-created self-referencing ordered dictionaries from
1247 becoming permanently uncollectable GC garbage. The downside is that
1248 removing __del__ means that the internal doubly-linked list has to wait for
1249 GC collection rather than freeing memory immediately when the refcnt drops
1250 to zero.

1280
R. David Murray7c4bf552010-08-25 01:45:57 +00001281- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1282 character years even if the message contains RFC822 two character years.
1283

1313 and a BadZipfile error is raised if it doesn't match (as used to be the
1314 case in Python 2.5 and earlier).

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001316- Issue #9550: a BufferedReader could issue an additional read when the
1317 original read request had been satisfied, which could block indefinitely
1318 when the underlying raw IO channel was e.g. a socket. Report and original
1319 patch by Jason V. Miller.

1711 of the number of bytes specified by the start byte.
1712 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1713 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1724 objects. (1) The comparison could incorrectly return True in some cases
1725 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002070 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2093-----------------
2094
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002095- Issue #7301: Add environment variable $PYTHONWARNINGS.
2096
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002097- Issue #8329: Don't return the same lists from select.select when no fds are
2098 changed.
2099
Georg Brandlfee0f442010-05-22 21:26:21 +00002100- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002101 on 64-bit machines. The shift count for either left or right shift is
2102 permitted to be up to sys.maxsize.
2103
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002104- Ensure that tokenization of identifiers is not affected by locale.

2109
Georg Brandlfee0f442010-05-22 21:26:21 +00002110- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2111 with a non-empty format string. This is an effort to future-proof user
2112 code. If a derived class does not currently implement __format__ but later
2113 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002114 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002115 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002116
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002117- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002130- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002131 (SIGINT). If an error occurs while importing the site module, the error is

2147
Georg Brandlfee0f442010-05-22 21:26:21 +00002148- Issue #8257: The Decimal construct now accepts a float instance directly,
2149 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002150
2151 >>> Decimal(1.1)
2152 Decimal('1.100000000000000088817841970012523233890533447265625')
2153
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002154- collections.Counter() now supports a subtract() method.
2155
Georg Brandlfee0f442010-05-22 21:26:21 +00002156- The functools module now has a total_ordering() class decorator to simplify
2157 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002165- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2166 InvalidOperation instead of returning False. (Comparisons involving a quiet
2167 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2168 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002169
Georg Brandlfee0f442010-05-22 21:26:21 +00002170- Issue #2531: Comparison operations between floats and Decimal instances now
2171 return a result based on the numeric values of the operands; previously they
2172 returned an arbitrary result based on the relative ordering of id(float) and
2173 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002174
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002175- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002176 argument `-` which tells it to read files to compile from stdin. Each line is
2177 read on demand and the named file is compiled immediately. (Original patch by
2178 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002183- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2184 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002185 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002186
Georg Brandlfee0f442010-05-22 21:26:21 +00002187- Comparisons using one of <, <=, >, >= between a complex instance and a
2188 Fractions instance now raise TypeError instead of returning True/False. This
2189 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2190 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002245- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002246 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2247 log file to compute the next rollover time. If the log file does not exist,
2248 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002289- Issue #8300: When passing a non-integer argument to struct.pack with any
2290 integer format code, struct.pack first attempts to convert the non-integer
2291 using its __index__ method. If that method is non-existent or raises
2292 TypeError it goes on to try the __int__ method, as described below.
2293
Georg Brandlba83f822010-03-14 09:50:54 +00002294- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2295 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2296 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002297 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2298 inconsistent: __int__ was used for some integer codes but not for others, and
2299 the set of integer codes for which it was used differed between native packing
2300 and standard packing.)

2548 and add the additional members returned in an OSVERSIONINFOEX structure. The
2549 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002552- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2553 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2554 returning NULL. The macro now returns a statically allocated empty string
2555 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002601 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002607- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002608 file position when calling `truncate()`. It would previously change the file
2609 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002610 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2611

2613 class used to represent files stored inside an archive. The new
2614 implementation is significantly faster and can be wrapped in a
2615 ``io.BufferedReader`` object for more speedups. It also solves an issue
2616 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002627- Issue #7748: Since unicode values are supported for some metadata options in
2628 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2629 encoded string for them. This ensures that the upload and register commands
2630 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002901- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2902 decimal string that's guaranteed to round back to x under correct rounding
2903 (with round-half-to-even rounding mode). Previously it gave a string based on
2904 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2905 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2906 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002907
Georg Brandlba83f822010-03-14 09:50:54 +00002908- Issue #7117: On almost all platforms: float-to-string and string-to-float
2909 conversions within Python are now correctly rounded. Places these conversions
2910 occur include: str for floats and complex numbers; the float and complex
2911 constructors; old-style and new-style numeric formatting; serialization and
2912 deserialization of floats and complex numbers using marshal, pickle and json;
2913 parsing of float and imaginary literals in Python code; Decimal-to-float
2914 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002915
Georg Brandlba83f822010-03-14 09:50:54 +00002916 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2917 providing correctly-rounded strtod and dtoa C functions. This code is
2918 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2919 the C compiler. There may be a small number of platforms on which correct
2920 operation of this code cannot be guaranteed, so the code is not used: notably,
2921 this applies to platforms where the C double format is not IEEE 754 binary64,
2922 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2923 and Python's configure script is unable to determine how to change the FPU
2924 precision. On these platforms conversions use the platform strtod and dtoa,
2925 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002927- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2928 uses the correctly-rounded string <-> float conversions described above (when
2929 available), and so produces correctly rounded results that will display nicely
2930 under the float repr. There are two related small changes: (1) round now
2931 accepts any class with an ``__index__()`` method for its second argument (but
2932 no longer accepts floats for the second argument), and (2) an excessively
2933 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2934 raises an exception.

3084 of 12. Previously, the behavior the same but with a default precision of 6.
3085 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00003196- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003197 were suppressing all exceptions. These include list(), filter(), map(),

3199
Benjamin Peterson596d3062009-01-19 15:42:23 +00003200- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00003227- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3228 existing .py counterpart, override the co_filename attributes of all code
3229 objects if the original filename is obsolete (which can happen if the file has

3284
Georg Brandlba83f822010-03-14 09:50:54 +00003285- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3286 file objects with closefd=False. The file descriptor is still kept open but
3287 the file object behaves like a closed file. The ``FileIO`` object also got a
3288 new readonly attribute ``closefd``.

3307
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003308- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003311- On windows, ``os.chdir()`` given unicode was not working if
3312 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3313 this code path is really executed because I cannot move to such directory on
3314 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003316- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3317 element is temporarily replaced with an equivalent frozenset. But the
3318 eventual KeyError would always report the empty ``frozenset()`` as the missing
3319 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003339- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3340 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3341 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3342 of using the replace error handler in PyUnicode_DecodeUTF8().
3343
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003344- Issue #3739: The unicode-internal encoder now reports the number of characters

3346
Georg Brandlba83f822010-03-14 09:50:54 +00003347- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3348 allocator will be automatically disabled when running under Valgrind. This
3349 gives improved memory leak detection when running under Valgrind, while taking
3350 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00003422 __main__.py file. This allows applications that run other Python scripts to
3423 support the same flexibility as the CPython command line itself.

4716
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004717- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4718 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4719 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4720 ``printf`` function, whereas PyString_FromFormat has an independent
4721 implementation and uses "%zd" on all platforms for size_t values.
4722 This makes a difference on win64, where ``printf`` needs "%Id" to display
4723 64bit values.

4729 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00004742- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004743 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4744 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4745 when given a tuple of classes as second argument, were looking up
4746 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4747 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004818 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4819 for catch_warnings() also led to an improvement in the raising of a
4820 DeprecationWarning related to warnings.warn_explicit().
4821
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004822- The deprecation warnings for the old camelCase threading API were removed.
4823

Christian Heimesa27a62e2008-08-22 19:55:54 +00004826- Silenced a trivial compiler warning in the sqlite module.
4827
Christian Heimes1cc69632008-08-22 20:10:27 +00004828- Fixed two format strings in the _collections module.
4829

Jesse Noller438195f2009-01-18 21:04:36 +00004842- Issue #4301: Patch the logging module to add processName support, remove
4843 _check_logger_class from multiprocessing.
4844
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004845- Issue #2975: When compiling several extension modules with Visual Studio 2008
4846 from the same python interpreter, some environment variables would grow
4847 without limit.
4848
Benjamin Peterson37346b22008-08-23 20:27:43 +00004849- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4850 exploitation of poor argument checking.
4851
Gerhard Häringef2276b2008-09-12 13:54:06 +00004852- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4853
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004854- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4855 remaining ones have "pysqlite_" prefix.
4856
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004857- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4865 wrapper for warnings.catch_warnings() that makes it easier to check
4866 that expected warning messages are being reported.
4867

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004886What's New in Python 2.6 beta 3?
4887================================
4888
Barry Warsaw07a4a382008-08-21 01:15:08 +00004889*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004890
4891Core and Builtins
4892-----------------
4893
Guido van Rossumf8402962008-08-20 15:01:50 +00004894- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4895 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4896 extensions do not automatically benefit from the class attribute
4897 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4898 to their tp_flags field if they care. This is a backwards
4899 compatibility feature; in 3.0, all types will use the cache by
4900 default.
4901
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004902- Keyword arguments can now follow starred arguments. (``f(a, *args,
4903 keyword=23)`` is now valid syntax.)
4904
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004905- ctypes function pointers that are COM methods have a boolean True
4906 value again.
4907
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004908- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4909 by denying s# to parse objects that have a releasebuffer procedure,
4910 and introducing s*.
4911
Georg Brandl1e13ea92008-08-11 09:07:59 +00004912- Issue #3537: Fix an assertion failure when an empty but presized dict
4913 object was stored in the freelist.
4914
Mark Dickinsonb6467572008-08-04 21:30:09 +00004915- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4916 ValueError consistently across platforms.
4917
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004918- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4919 (64bit Unix, for example), unichr() would truncate its argument and return
4920 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4921
Neal Norwitze7d8be82008-07-31 17:17:14 +00004922- Apply security patches from Apple.
4923
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004924- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4925 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4926
Antoine Pitrou92f82162008-07-25 22:22:08 +00004927- Issue #1819: function calls with several named parameters are now on
4928 average 35% faster (as measured by pybench).
4929
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004930- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4931 the python debugger steps into a class statement: the free variables (local
4932 variables defined in an outer scope) would be deleted from the outer scope.
4933
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004934- Issue #2620: Overflow checking when allocating or reallocating memory
4935 was not always being done properly in some python types and extension
4936 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4937 all been updated to perform better checks and places in the code that
4938 would previously leak memory on the error path when such an allocation
4939 failed have been fixed.
4940
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004941Library
4942-------
4943

4945
Benjamin Petersone977ad42008-08-20 01:42:01 +00004946- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4947 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4948
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004949- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4950 version reported by these tools does not necessarily follow the python
4951 version numbering scheme, so the module is less strict when parsing it.
4952
Nick Coghlanf70385a2008-08-18 12:42:46 +00004953- Issue #2235: Added Py3k warnings for types which will become unhashable
4954 under the stricter __hash__ inheritance rules in 3.0. Several types
4955 which did not meet the rules for hash invariants and were already
4956 unhashable in 3.0 have now been explicitly flagged as unhashable in
4957 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4958 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4959
Brett Cannon88f801d2008-08-18 00:46:22 +00004960- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4961 imported into the module but exposed as part of the module's API.
4962
Brett Cannon7b96f072008-08-18 00:41:11 +00004963- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4964
Brett Cannon46225e72008-08-18 00:36:52 +00004965- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004967- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4968
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004969- Issue #3575: Incremental decoder's decode function now takes bytearray
4970 by using 's*' instead of 't#'.
4971
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004972- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004973 fails unicode conversion on 2nd parameter. (windows only)
4974
Georg Brandl222e2082010-08-01 22:27:39 +00004975- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004976 in a redirect.
4977
Brett Cannonabe423e2008-08-16 21:47:07 +00004978- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004979 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004980
Facundo Batistaeb90b782008-08-16 14:44:07 +00004981- Issue #2776: fixed small issue when handling an URL with double slash
4982 after a 302 response in the case of not going through a proxy.
4983
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004984- Issue #2676: in the email package, content-type parsing was hanging on
4985 pathological input because of quadratic or exponential behaviour of a
4986 regular expression.
4987
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004988- Issue #3476: binary buffered reading through the new "io" library is now
4989 thread-safe.
4990
Brett Cannonbf3157b2008-08-14 05:00:03 +00004991- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4992 since mimetools itself is deprecated. Because modules are cached, all
4993 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4994
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004995- Issue #3134: shutil referenced undefined WindowsError symbol.
4996
Robert Schuppenies14646332008-08-10 11:01:53 +00004997- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4998 menu entries were not deleted.
4999
Brett Cannon83e81842008-08-09 23:30:55 +00005000- Copied the implementation of reduce() to _functools.reduce() to have a
5001 version that did not raise a DeprecationWarning under -3.
5002
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005003- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5004 a MemoryError rather than silently stop the iteration.
5005
Guido van Rossum59ce9012008-08-09 14:55:34 +00005006- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5007 to _sre.compile() will now be rejected. This should not affect anybody
5008 since the re.compile() function never generates invalid re-bytecode.
5009
Skip Montanaroa032bf42008-08-08 22:52:51 +00005010- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5011 upon first access it can be automatically initialized from the csv file if
5012 it wasn't initialized during instantiation.
5013
Brett Cannon3aa2a492008-08-06 22:28:09 +00005014- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5015 the reload() built-in has been removed.
5016
Brett Cannon7e30b672008-08-04 21:52:25 +00005017- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005018 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005029 asking for a specific length. This problem only affected files opened
5030 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005031

5056 file name rather than a ZipInfo instance, so files are extracted with
5057 mode 0600 rather than 000 under Unix.
5058
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005059- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5060 argument in python 2.5, this broke code that subclassed Popen to include its
5061 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5075 coverage of the lookup process for special methods. The disclaimers
5076 regarding lack of coverage of new-style classes have also been
5077 removed, since the coverage is now fairly reasonable.

5086-----------------
5087
Georg Brandl3e483f62008-07-16 22:57:41 +00005088- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5089 its methods now allow for items objects that can be converted to
5090 an integer using operator.index().
5091
Mark Dickinson64b7e502008-07-16 09:40:03 +00005092- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5093 produced a ValueError instead of giving the correct float.
5094
Eric Smitha5fa5a22008-07-16 00:11:49 +00005095- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5096 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5097
Mark Dickinson7103aa42008-07-15 19:08:33 +00005098- Issue #3008: the float type has a new instance method 'float.hex'
5099 and a new class method 'float.fromhex' to convert floating-point
5100 numbers to and from hexadecimal strings, respectively.
5101
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005102- Issue #2235: __hash__ is once again inherited by default. To allow
5103 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00005109- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5110 the parent module cannot be found while performing an absolute import.
5111 This means that an incorrectly defined __package__ attribute will
5112 now only prevent relative imports in that module rather than causing
5113 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005127- Issue #3004: Minor change to slice.indices(): the start and stop
5128 arguments are now treated identically, making the behaviour easier
5129 to describe and understand. For example, slice(None, -10,
5130 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5131 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5132 10, -1).

5635 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005648- Issue #1631171: Re-implement the 'warnings' module in C (the
5649 original Python code has been kept as backup). This will allow for
5650 using the 'warning's machinery in such places as the parser where
5651 use of pure Python code is not possible. Both the ``showarning()``
5652 and ``formatwarning()`` gain an optional 'line' argument which is
5653 not called by default for backwards-compatibility reasons. Setting
5654 ``warnings.showwarning()`` to an implementation that lacks support
5655 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005718- Issue #2550: The approach used by client/server code for obtaining
5719 ports to listen on in network-oriented tests has been refined in an
5720 effort to facilitate running multiple instances of the entire
5721 regression test suite in parallel without issue.
5722 test_support.bind_port() has been fixed such that it will always
5723 return a unique port -- which wasn't always the case with the
5724 previous implementation, especially if socket options had been set
5725 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5726 new implementation of bind_port() will actually raise an exception
5727 if it is passed an AF_INET/SOCK_STREAM socket with either the
5728 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5729 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5730 the socket it's been passed. This currently only applies to
5731 Windows. This option prevents any other sockets from binding to the
5732 host/port we've bound to, thus removing the possibility of the
5733 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5734 when a second SOCK_STREAM socket binds and accepts to a host/port
5735 that's already been bound by another socket. The optional preferred
5736 port parameter to bind_port() has been removed. Under no
5737 circumstances should tests be hard coding ports!
5738
5739 test_support.find_unused_port() has also been introduced, which will
5740 pass a temporary socket object to bind_port() in order to obtain an
5741 unused port. The temporary socket object is then closed and
5742 deleted, and the port is returned. This method should only be used
5743 for obtaining an unused port in order to pass to an external program
5744 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5745 a parameter to a server-oriented class that doesn't give you direct
5746 access to the underlying socket used.
5747
5748 Finally, test_support.HOST has been introduced, which should be used
5749 for the host argument of any relevant socket calls (i.e. bind and
5750 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005751
5752 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005754 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5755 test_asynchat and test_socket_ssl.
5756
Georg Brandl3ee81df2008-05-17 18:14:43 +00005757 It is now possible for multiple instances of the regression test
5758 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006037- Added the future_builtins module, which contains hex() and oct().
6038 These are the PEP 3127 version of these functions, designed to be
6039 compatible with the hex() and oct() builtins from Python 3.0. They
6040 differ slightly in their output formats from the existing, unchanged
6041 Python 2.6 builtins. The expected usage of the future_builtins
6042 module is:
6043 from future_builtins import hex, oct
6044
Eric Smith7ef40bf2008-02-20 23:34:22 +00006045- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6046 exponents for exponents with absolute value < 100. Follows C99
6047 standard. This is a change on Windows, which would use 3 digits.
6048 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6049 so that any alterations it does to the resulting string will be
6050 available in stringlib/formatter.h (for float.__format__).
6051
Eric Smith5a3c1352008-02-19 13:21:56 +00006052- Implemented PEP 3101, Advanced String Formatting. This adds a new
6053 builtin format(); a format() method for str and unicode; a
6054 __format__() method to object, str, unicode, int, long, float, and
6055 datetime; the class string.Formatter; and the C API
6056 PyObject_Format().
6057
Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Fixed several potential crashes, all caused by specially crafted
6059 __del__ methods exploiting objects in temporarily inconsistent
6060 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006062- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063 prevent a possible crash: an Abstract Base Class would try to access
6064 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006065

Georg Brandl3ee81df2008-05-17 18:14:43 +00006069- Clear all free lists during a gc.collect() of the highest generation
6070 in order to allow pymalloc to free more arenas. Python may give back
6071 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006072
Georg Brandl3ee81df2008-05-17 18:14:43 +00006073- Issue #2045: Fix an infinite recursion triggered when printing a
6074 subclass of collections.defaultdict, if its default_factory is set
6075 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006076
Christian Heimesf75dbef2008-02-08 00:11:31 +00006077- Fixed a minor memory leak in dictobject.c. The content of the free
6078 list was not freed on interpreter shutdown.
6079
Georg Brandl21e99f42010-03-07 15:23:59 +00006080- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006082
Georg Brandl3ee81df2008-05-17 18:14:43 +00006083- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6084 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006085 to compact the internal free lists of pre-allocted ints and floats.
6086
Georg Brandl3ee81df2008-05-17 18:14:43 +00006087- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6088 calls. Python expected the return type int but the fork familie
6089 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006090
Georg Brandl3ee81df2008-05-17 18:14:43 +00006091- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6092 appear in the same code unit.

6101 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006102
Georg Brandl3ee81df2008-05-17 18:14:43 +00006103- Patch #1473257: generator objects gain a gi_code attribute. This is
6104 the same object as the func_code attribute of the function that
6105 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006106
Georg Brandl3ee81df2008-05-17 18:14:43 +00006107- Issue #1920: "while 0" statements were completely removed by the
6108 compiler, even in the presence of an "else" clause, which is
6109 supposed to be run when the condition is false. Now the compiler
6110 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006111
Guido van Rossumeead05f2008-01-24 18:21:02 +00006112- A few crashers fixed: weakref_in_del.py (issue #1377858);
6113 loosing_dict_ref.py (issue #1303614, test67.py);
6114 borrowed_ref_[34].py (not in tracker).
6115
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006116- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006117 suppressed while an extension is loaded by calling SetErrorMode in
6118 dynload_win.c. The error is still reported properly.
6119
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006121 several extension methods and modules do not work without unicode
6122 support.
6123
Georg Brandl26543b12008-01-21 18:36:51 +00006124- Issue #1882: when compiling code from a string, encoding cookies in the
6125 second line of code were not always recognized correctly.
6126
Georg Brandl14404b62008-01-19 19:27:05 +00006127- Issue #1679: "0x" was taken as a valid integer literal.
6128
Georg Brandl6caad7d2008-01-26 14:19:22 +00006129- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006130 added.
6131
Christian Heimesc94e2b52008-01-14 04:13:37 +00006132- sys.float_info / PyFloat_GetInfo: The floating point information
6133 object was converted from a dict to a specialized structseq object.
6134
Georg Brandl3ee81df2008-05-17 18:14:43 +00006135- Patch #1816: Added sys.flags structseq. It exposes the status of
6136 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006137
Georg Brandl3ee81df2008-05-17 18:14:43 +00006138- Objects/structseq.c: Implemented new structseq representation. The
6139 patch makes structseqs (e.g. the return value of os.stat) more
6140 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006141
Georg Brandl3ee81df2008-05-17 18:14:43 +00006142- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006154- Improve some exception messages when Windows fails to load an
6155 extension module. Now we get for example '%1 is not a valid Win32
6156 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006157

Christian Heimes0a8143f2007-12-18 23:22:54 +00006163- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006164 and INF. float("nan"), float("inf") and float("-inf") now work on
6165 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006166
Georg Brandl3ee81df2008-05-17 18:14:43 +00006167- Compiler now generates simpler and faster code for dictionary
6168 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00006215 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,

Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Issue #1686386: Tuple's tp_repr did not take into account the
6219 possibility of having a self-referential tuple, which is possible
6220 from C code. Nor did object's tp_str consider that a type's tp_str
6221 could do something that could lead to an inifinite recursion.
6222 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6223 issues.

6226 'print' statement to write to a file since the GIL was not released
6227 as needed. Now PyObject_Print() does the right thing along with
6228 various tp_print implementations of the built-in types and those in
6229 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006239 PyObject_Call() never calling back out to Python code to trigger
6240 recursion depth updates/checks. Required the creation of a static

6290
Guido van Rossum143b5642007-03-23 04:58:42 +00006291- Bug #1683368: The object.__init__() and object.__new__() methods are
6292 now stricter in rejecting excess arguments. The only time when
6293 either allows excess arguments is when it is not overridden and the
6294 other one is. For backwards compatibility, when both are
6295 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006296 warning later). Also, type.__init__() insists on the same signature
6297 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6300 object to complex using its __complex__() method before falling back
6301 to the __float__() method. Therefore, the functions in the cmath
6302 module now can operate on objects that define a __complex__()
6303 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006321- Bug #1678647: write a newline after printing an exception in any
6322 case, even when converting the value to a string failed.
6323
Georg Brandl871f1bc2007-03-12 13:17:36 +00006324- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006325 its argument, if it exists. If not, it will work like before. This
6326 allows customizing the output of dir() in the presence of a
6327 __getattr__().

6337 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006338
Georg Brandlaa2321b2007-03-07 00:40:28 +00006339- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006340 makes the filenames the warning module prints much more sensible
6341 when a PYTHONSTARTUP file is used.

6356
Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006910- Patch #1530482: add pydoc.render_doc() which returns the

6925
Georg Brandl92a6bae2007-03-13 17:43:32 +00006926- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006927 are set for invalid interpolation sequences that would lead to

6984 TestCase and TestSuite subclasses (not instances) are no longer
6985 accepted in TestSuite.addTest(). This should cause no

6987 -- the failure just occurred later, with a more cumbersome
6988 exception.

7270 with RFC 3207 and forgets any knowledge obtained from the server not
7271 obtained from the TLS negotiation itself. Patch contributed by Bill
7272 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007273
Georg Brandl3ee81df2008-05-17 18:14:43 +00007274- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007275 that the SMTP.starttls() caller no longer needs to call ehlo()
7276 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007277 does not claim to support starttls. Adds the
7278 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00007362

Georg Brandl3ee81df2008-05-17 18:14:43 +00007377 time so that opening a database previously created with the DB_DUP
7378 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7379 opens. Specifically: dictionary assignment to a DB object will
7380 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007661- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007662 periodic threadstate and signal checking in tight loops. By
7663 default, this option is turned-off. It should only be enabled in
7664 debugged, performance critical applications.

7720 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007721
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7723 to ``PyTuple_SetItem``, it can be used to populate a brand new
7724 frozenset; but it does not steal a reference to the added item.

7736
Georg Brandl3ee81df2008-05-17 18:14:43 +00007737- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7738 of w# format code incorrectly truncated the length to an int, even
7739 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7740 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007741

Georg Brandl3ee81df2008-05-17 18:14:43 +00007770- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7771 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
