310 fix various SSLSocket methods to raise socket.error rather than an
311 unhelpful TypeError when called on an unconnected socket. Original patch
312 by Andrew Bennetts.

321
Raymond Hettinger20397532010-09-12 02:11:45 +0000322- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
323 This prevents user-created self-referencing ordered dictionaries from
324 becoming permanently uncollectable GC garbage. The downside is that
325 removing __del__ means that the internal doubly-linked list has to wait for
326 GC collection rather than freeing memory immediately when the refcnt drops
327 to zero.
328

336 original error is re-raised.

786 start byte and the continuation byte(s) are now considered invalid, instead
787 of the number of bytes specified by the start byte.
788 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
789 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
790 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

801 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001145- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001146 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1147 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1148 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +00001166*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00001167
1168Core and Builtins
1169-----------------
1170
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001171- Issue #7301: Add environment variable $PYTHONWARNINGS.
1172
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001173- Issue #8329: Don't return the same lists from select.select when no fds are
1174 changed.
1175
Georg Brandlfee0f442010-05-22 21:26:21 +00001176- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001177 on 64-bit machines. The shift count for either left or right shift is
1178 permitted to be up to sys.maxsize.
1179
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001180- Ensure that tokenization of identifiers is not affected by locale.
1181
Georg Brandlfee0f442010-05-22 21:26:21 +00001182- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001183
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001184- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1185
Georg Brandlfee0f442010-05-22 21:26:21 +00001186- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1187 with a non-empty format string. This is an effort to future-proof user
1188 code. If a derived class does not currently implement __format__ but later
1189 adds its own __format__, it would most likely break user code that had
1190 supplied a format string. This will be changed to a DeprecationWaring in
1191 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001192
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001193- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner95affc42010-03-22 12:24:37 +00001200
Benjamin Peterson96545892010-03-21 20:21:00 +00001201- Issue #6474: Make error message from passing an inadequate number of keyword
1202 arguments to a function correct.
1203
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001204- Issue #8164: Don't allow lambda functions to have a docstring.
1205
Victor Stinner66644262010-03-10 22:30:19 +00001206- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001207 (SIGINT). If an error occurs while importing the site module, the error is
1208 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001209 module.

1217
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001218- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001219 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1220 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001222- Issue #8310: Allow dis to examine new style classes.
1223
Georg Brandlfee0f442010-05-22 21:26:21 +00001224- Issue #8257: The Decimal construct now accepts a float instance directly,
1225 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001226
1227 >>> Decimal(1.1)
1228 Decimal('1.100000000000000088817841970012523233890533447265625')
1229
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001230- collections.Counter() now supports a subtract() method.
1231
Georg Brandlfee0f442010-05-22 21:26:21 +00001232- The functools module now has a total_ordering() class decorator to simplify
1233 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001234
Georg Brandlfee0f442010-05-22 21:26:21 +00001235- The functools module also adds cmp_to_key() as a tool to transition old-style
1236 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001237
Georg Brandlfee0f442010-05-22 21:26:21 +00001238- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1239 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001240
Georg Brandlfee0f442010-05-22 21:26:21 +00001241- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1242 InvalidOperation instead of returning False. (Comparisons involving a quiet
1243 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1244 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001245
Georg Brandlfee0f442010-05-22 21:26:21 +00001246- Issue #2531: Comparison operations between floats and Decimal instances now
1247 return a result based on the numeric values of the operands; previously they
1248 returned an arbitrary result based on the relative ordering of id(float) and
1249 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001250
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001251- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001252 argument `-` which tells it to read files to compile from stdin. Each line is
1253 read on demand and the named file is compiled immediately. (Original patch by
1254 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001255
Georg Brandlfee0f442010-05-22 21:26:21 +00001256- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1257 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001259- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1260 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001261 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001262
Georg Brandlfee0f442010-05-22 21:26:21 +00001263- Comparisons using one of <, <=, >, >= between a complex instance and a
1264 Fractions instance now raise TypeError instead of returning True/False. This
1265 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1266 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001267
Michael Foorde6410c52010-03-29 20:04:23 +00001268- Addition of ``WeakSet`` to the ``weakref`` module.

1276
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001277- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001278 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1279 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001280
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001281- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1282 deprecated.
1283
Georg Brandlfee0f442010-05-22 21:26:21 +00001284- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1285 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001286

1291 existing at the same time, causing a Unicode error when configuration code
1292 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001293
Georg Brandlfee0f442010-05-22 21:26:21 +00001294- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1295 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001296

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001321- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001322 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1323 log file to compute the next rollover time. If the log file does not exist,
1324 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001325
Georg Brandlba83f822010-03-14 09:50:54 +00001326- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001334- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1335 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1336 This is a behavior change, so email's minor version number is now bumped, to
1337 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001365- Issue #8300: When passing a non-integer argument to struct.pack with any
1366 integer format code, struct.pack first attempts to convert the non-integer
1367 using its __index__ method. If that method is non-existent or raises
1368 TypeError it goes on to try the __int__ method, as described below.
1369
Georg Brandlba83f822010-03-14 09:50:54 +00001370- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1371 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1372 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001373 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1374 inconsistent: __int__ was used for some integer codes but not for others, and
1375 the set of integer codes for which it was used differed between native packing
1376 and standard packing.)

1781-----------------
1782
Georg Brandlba83f822010-03-14 09:50:54 +00001783- The ``__complex__()`` method is now looked up on the class of instances to
1784 make it consistent with other special methods.

1788
Mark Dickinson1b34d252010-01-01 17:27:30 +00001789- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001790 DeprecationWarning when passed a float argument where an integer was expected.
1791 These functions and methods now raise TypeError instead. The majority of the
1792 effects of this change are in the extension modules, but some core functions
1793 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1794 and many unicode/str methods.

1808 of integers: the result of a/b is now correctly rounded for ints a and b (at
1809 least on IEEE 754 platforms), and in particular does not depend on the
1810 internal representation of a long.

1818
Georg Brandlba83f822010-03-14 09:50:54 +00001819 These executables now work properly with the arch(1) command: ``arch -ppc
1820 python`` will start a universal binary version of python in PPC mode (unlike

1961 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001962
Georg Brandlba83f822010-03-14 09:50:54 +00001963- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1964 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001965
Georg Brandlba83f822010-03-14 09:50:54 +00001966- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Georg Brandlba83f822010-03-14 09:50:54 +00001977- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1978 decimal string that's guaranteed to round back to x under correct rounding
1979 (with round-half-to-even rounding mode). Previously it gave a string based on
1980 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1981 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1982 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001983
Georg Brandlba83f822010-03-14 09:50:54 +00001984- Issue #7117: On almost all platforms: float-to-string and string-to-float
1985 conversions within Python are now correctly rounded. Places these conversions
1986 occur include: str for floats and complex numbers; the float and complex
1987 constructors; old-style and new-style numeric formatting; serialization and
1988 deserialization of floats and complex numbers using marshal, pickle and json;
1989 parsing of float and imaginary literals in Python code; Decimal-to-float
1990 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001991
Georg Brandlba83f822010-03-14 09:50:54 +00001992 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1993 providing correctly-rounded strtod and dtoa C functions. This code is
1994 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1995 the C compiler. There may be a small number of platforms on which correct
1996 operation of this code cannot be guaranteed, so the code is not used: notably,
1997 this applies to platforms where the C double format is not IEEE 754 binary64,
1998 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1999 and Python's configure script is unable to determine how to change the FPU
2000 precision. On these platforms conversions use the platform strtod and dtoa,
2001 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002003- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2004 uses the correctly-rounded string <-> float conversions described above (when
2005 available), and so produces correctly rounded results that will display nicely
2006 under the float repr. There are two related small changes: (1) round now
2007 accepts any class with an ``__index__()`` method for its second argument (but
2008 no longer accepts floats for the second argument), and (2) an excessively
2009 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2010 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002152
Georg Brandlba83f822010-03-14 09:50:54 +00002153 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2154 (2) parsing of strings representing infinities and nans was locale aware; and
2155 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002156
Georg Brandlba83f822010-03-14 09:50:54 +00002157- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2158 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2159 but with at least one decimal point and with a default precision
2160 of 12. Previously, the behavior the same but with a default precision of 6.
2161 This more closely matches ``str()``, and reduces surprises when adding
2162 alignment flags to the empty presentation type. This also affects the new
2163 complex.__format__ in the same way.
2164
2165- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2166 classtype's, even if it was None. property now inserts the __doc__ into the

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002227- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002228 untrackable objects are not tracked by the garbage collector. This can reduce
2229 the size of collections and therefore the garbage collection overhead on

2237 internal representation of integers, for performance reasons. Base 2**30 is
2238 enabled by default on 64-bit machines. Add --enable-big-digits option to
2239 configure, which overrides the default. Add sys.long_info structseq to
2240 provide information about the internal format.

2363 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002387- On windows, ``os.chdir()`` given unicode was not working if
2388 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2389 this code path is really executed because I cannot move to such directory on
2390 win2k)

2393 element is temporarily replaced with an equivalent frozenset. But the
2394 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002415- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2416 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2417 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2418 of using the replace error handler in PyUnicode_DecodeUTF8().
2419
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002420- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002423- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2425 gives improved memory leak detection when running under Valgrind, while taking
2426 advantage of pymalloc at other times.

3792
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003793- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3794 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3795 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3796 ``printf`` function, whereas PyString_FromFormat has an independent
3797 implementation and uses "%zd" on all platforms for size_t values.
3798 This makes a difference on win64, where ``printf`` needs "%Id" to display
3799 64bit values.

3805 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003816 was correctly parsed but parsing of subsequent arguments failed.
3817
Vinay Sajip35e3b032008-09-01 14:33:59 +00003818- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003819 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3820 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3821 when given a tuple of classes as second argument, were looking up
3822 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3823 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00003970- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3971 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3972 extensions do not automatically benefit from the class attribute
3973 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3974 to their tp_flags field if they care. This is a backwards
3975 compatibility feature; in 3.0, all types will use the cache by
3976 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00003978- Keyword arguments can now follow starred arguments. (``f(a, *args,
3979 keyword=23)`` is now valid syntax.)
3980
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003981- ctypes function pointers that are COM methods have a boolean True
3982 value again.
3983
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003984- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3985 by denying s# to parse objects that have a releasebuffer procedure,
3986 and introducing s*.
3987
Georg Brandl1e13ea92008-08-11 09:07:59 +00003988- Issue #3537: Fix an assertion failure when an empty but presized dict
3989 object was stored in the freelist.
3990
Mark Dickinsonb6467572008-08-04 21:30:09 +00003991- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3992 ValueError consistently across platforms.
3993
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003994- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3995 (64bit Unix, for example), unichr() would truncate its argument and return
3996 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3997
Neal Norwitze7d8be82008-07-31 17:17:14 +00003998- Apply security patches from Apple.
3999
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004000- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4001 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4002
Antoine Pitrou92f82162008-07-25 22:22:08 +00004003- Issue #1819: function calls with several named parameters are now on
4004 average 35% faster (as measured by pybench).
4005
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004006- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4007 the python debugger steps into a class statement: the free variables (local
4008 variables defined in an outer scope) would be deleted from the outer scope.
4009
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004010- Issue #2620: Overflow checking when allocating or reallocating memory
4011 was not always being done properly in some python types and extension
4012 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4013 all been updated to perform better checks and places in the code that
4014 would previously leak memory on the error path when such an allocation
4015 failed have been fixed.

4021
Benjamin Petersone977ad42008-08-20 01:42:01 +00004022- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4023 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4024
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004025- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4026 version reported by these tools does not necessarily follow the python
4027 version numbering scheme, so the module is less strict when parsing it.
4028
Nick Coghlanf70385a2008-08-18 12:42:46 +00004029- Issue #2235: Added Py3k warnings for types which will become unhashable
4030 under the stricter __hash__ inheritance rules in 3.0. Several types
4031 which did not meet the rules for hash invariants and were already
4032 unhashable in 3.0 have now been explicitly flagged as unhashable in
4033 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4034 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4035
Brett Cannon88f801d2008-08-18 00:46:22 +00004036- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4037 imported into the module but exposed as part of the module's API.
4038

4044
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004045- Issue #3575: Incremental decoder's decode function now takes bytearray
4046 by using 's*' instead of 't#'.
4047
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004048- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004049 fails unicode conversion on 2nd parameter. (windows only)

Brett Cannon721b1452008-08-16 22:00:27 +00004055 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004056
Facundo Batistaeb90b782008-08-16 14:44:07 +00004057- Issue #2776: fixed small issue when handling an URL with double slash
4058 after a 302 response in the case of not going through a proxy.
4059
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004060- Issue #2676: in the email package, content-type parsing was hanging on
4061 pathological input because of quadratic or exponential behaviour of a
4062 regular expression.
4063
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004064- Issue #3476: binary buffered reading through the new "io" library is now
4065 thread-safe.
4066
Brett Cannonbf3157b2008-08-14 05:00:03 +00004067- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4068 since mimetools itself is deprecated. Because modules are cached, all
4069 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4070
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004071- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00004073- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4074 menu entries were not deleted.
4075
Brett Cannon83e81842008-08-09 23:30:55 +00004076- Copied the implementation of reduce() to _functools.reduce() to have a
4077 version that did not raise a DeprecationWarning under -3.
4078
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004079- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4080 a MemoryError rather than silently stop the iteration.
4081
Guido van Rossum59ce9012008-08-09 14:55:34 +00004082- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4083 to _sre.compile() will now be rejected. This should not affect anybody
4084 since the re.compile() function never generates invalid re-bytecode.
4085
Skip Montanaroa032bf42008-08-08 22:52:51 +00004086- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4087 upon first access it can be automatically initialized from the csv file if
4088 it wasn't initialized during instantiation.
4089
Brett Cannon3aa2a492008-08-06 22:28:09 +00004090- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4091 the reload() built-in has been removed.
4092
Brett Cannon7e30b672008-08-04 21:52:25 +00004093- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004094 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4102 raised an AttributeError.
4103
Benjamin Peterson01a24322008-07-28 23:35:27 +00004104- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004105 asking for a specific length. This problem only affected files opened
4106 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004107

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004131- Issue #3394: zipfile.writestr sets external attributes when passed a
4132 file name rather than a ZipInfo instance, so files are extracted with
4133 mode 0600 rather than 000 under Unix.
4134
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004135- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4136 argument in python 2.5, this broke code that subclassed Popen to include its
4137 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004147- Issue #2235: the C API function PyObject_HashNotImplemented and its
4148 interaction with the tp_hash slot (added in 2.6b2) are now documented
4149
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004150- Issue #643841: The language reference now provides more detailed
4151 coverage of the lookup process for special methods. The disclaimers
4152 regarding lack of coverage of new-style classes have also been
4153 removed, since the coverage is now fairly reasonable.

4157================================
4158
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004159*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004161Core and Builtins
4162-----------------
4163
Georg Brandl3e483f62008-07-16 22:57:41 +00004164- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4165 its methods now allow for items objects that can be converted to
4166 an integer using operator.index().
4167
Mark Dickinson64b7e502008-07-16 09:40:03 +00004168- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4169 produced a ValueError instead of giving the correct float.
4170
Eric Smitha5fa5a22008-07-16 00:11:49 +00004171- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4172 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4173
Mark Dickinson7103aa42008-07-15 19:08:33 +00004174- Issue #3008: the float type has a new instance method 'float.hex'
4175 and a new class method 'float.fromhex' to convert floating-point
4176 numbers to and from hexadecimal strings, respectively.
4177
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004178- Issue #2235: __hash__ is once again inherited by default. To allow
4179 collections.Hashable to remain meaningful in the presence of the
4180 default hash implementation (object.__hash__), it is now possible
4181 to explicit block inheritance of hash by setting __hash__=None at
4182 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4183 level.
4184
Nick Coghlanb028f502008-07-13 14:52:36 +00004185- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4186 the parent module cannot be found while performing an absolute import.
4187 This means that an incorrectly defined __package__ attribute will
4188 now only prevent relative imports in that module rather than causing
4189 all imports from that module to fail.
4190
Nick Coghlan14ff9942008-07-08 14:21:42 +00004191- Issue #2517: Allow unicode messages in Exceptions again by correctly
4192 bypassing the instance dictionary when looking up __unicode__ on
4193 new-style classes.
4194
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004195- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4196 set to a custom object whose write() method happens to install
4197 another file in sys.stdout.
4198
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004199- Issue #3088: Corrected a race condition in classes derived from
4200 threading.local: the first member set by a thread could be saved in
4201 another thread's dictionary.
4202
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004203- Issue #3004: Minor change to slice.indices(): the start and stop
4204 arguments are now treated identically, making the behaviour easier
4205 to describe and understand. For example, slice(None, -10,
4206 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4207 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4208 10, -1).
4209
Georg Brandl278fc502008-07-19 12:46:12 +00004210- Issue #3219: Calling a function with repeated keyword arguments,
4211 f(a=2, a=23), would not cause a syntax error. This was a regression
4212 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004213
Georg Brandl278fc502008-07-19 12:46:12 +00004214- Issue #2862: Make int and float freelist management consistent with
4215 other freelists. Changes their CompactFreeList apis into
4216 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004217

4220
Thomas Heller57adf222008-08-14 19:10:48 +00004221- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4222 api functions without holding the GIL, which could lead to a fatal
4223 error when they failed.
4224
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004225- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4234 ForkingPickler.register() to resolve conflict with ctypes.
4235
Vinay Sajip51e65192008-07-18 09:01:10 +00004236- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004237
Thomas Heller880f5292008-07-15 19:39:38 +00004238- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4239 a valid dlerror() message.
4240
Thomas Heller2bad6572008-07-15 17:19:50 +00004241- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4242 incomplete structure was created.
4243
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004244- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00004246- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4247
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004248- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004249
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004250- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4251 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004252 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004253 content-length. The problem had been corrected in the 2.4 branch, but never
4254 merged into trunk.
4255
Georg Brandle78fbcc2008-07-05 10:13:36 +00004256- Issue #2663: add filtering capability to shutil.copytree().

4661 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004662 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004663
4664 This is controlled by the configure argument ``--with-universal-archs``:
4665
4666 - ``--with-universal-archs=all``: install 4-way universal
4667
4668 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4669
4670 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4671
4672 This option should be used in combination with ``--enable-universalsdk=``.
4673
4674 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Issue #1631171: Re-implement the 'warnings' module in C (the
4725 original Python code has been kept as backup). This will allow for
4726 using the 'warning's machinery in such places as the parser where
4727 use of pure Python code is not possible. Both the ``showarning()``
4728 and ``formatwarning()`` gain an optional 'line' argument which is
4729 not called by default for backwards-compatibility reasons. Setting
4730 ``warnings.showwarning()`` to an implementation that lacks support
4731 for the ``line`` argument will raise a DeprecationWarning.

4755
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004756- The getpass module has been improved on Unix. It now uses /dev/tty
4757 by default and uses stderr instead of stdout. A GetPassWarning is
4758 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004794- Issue #2550: The approach used by client/server code for obtaining
4795 ports to listen on in network-oriented tests has been refined in an
4796 effort to facilitate running multiple instances of the entire
4797 regression test suite in parallel without issue.
4798 test_support.bind_port() has been fixed such that it will always
4799 return a unique port -- which wasn't always the case with the
4800 previous implementation, especially if socket options had been set
4801 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4802 new implementation of bind_port() will actually raise an exception
4803 if it is passed an AF_INET/SOCK_STREAM socket with either the
4804 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4805 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4806 the socket it's been passed. This currently only applies to
4807 Windows. This option prevents any other sockets from binding to the
4808 host/port we've bound to, thus removing the possibility of the
4809 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4810 when a second SOCK_STREAM socket binds and accepts to a host/port
4811 that's already been bound by another socket. The optional preferred
4812 port parameter to bind_port() has been removed. Under no
4813 circumstances should tests be hard coding ports!
4814
4815 test_support.find_unused_port() has also been introduced, which will
4816 pass a temporary socket object to bind_port() in order to obtain an
4817 unused port. The temporary socket object is then closed and
4818 deleted, and the port is returned. This method should only be used
4819 for obtaining an unused port in order to pass to an external program
4820 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4821 a parameter to a server-oriented class that doesn't give you direct
4822 access to the underlying socket used.
4823
4824 Finally, test_support.HOST has been introduced, which should be used

5101-----------------
5102
Fred Drakea8ee94b2008-03-01 02:45:07 +00005103- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005104 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005105
Georg Brandlad61bc82008-02-23 15:11:18 +00005106- Issue #2067: file.__exit__() now calls subclasses' close() method.
5107
5108- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005109
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005110- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005111 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005112
Eric Smitha73fbe72008-02-23 03:09:44 +00005113- Added the future_builtins module, which contains hex() and oct().
5114 These are the PEP 3127 version of these functions, designed to be
5115 compatible with the hex() and oct() builtins from Python 3.0. They
5116 differ slightly in their output formats from the existing, unchanged
5117 Python 2.6 builtins. The expected usage of the future_builtins
5118 module is:
5119 from future_builtins import hex, oct
5120
Eric Smith7ef40bf2008-02-20 23:34:22 +00005121- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5122 exponents for exponents with absolute value < 100. Follows C99
5123 standard. This is a change on Windows, which would use 3 digits.
5124 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5125 so that any alterations it does to the resulting string will be
5126 available in stringlib/formatter.h (for float.__format__).
5127
Eric Smith5a3c1352008-02-19 13:21:56 +00005128- Implemented PEP 3101, Advanced String Formatting. This adds a new
5129 builtin format(); a format() method for str and unicode; a
5130 __format__() method to object, str, unicode, int, long, float, and
5131 datetime; the class string.Formatter; and the C API
5132 PyObject_Format().
5133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Fixed several potential crashes, all caused by specially crafted
5135 __del__ methods exploiting objects in temporarily inconsistent
5136 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005137
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005138- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139 prevent a possible crash: an Abstract Base Class would try to access
5140 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Fixed repr() and str() of complex numbers with infinity or nan as
5143 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Clear all free lists during a gc.collect() of the highest generation
5146 in order to allow pymalloc to free more arenas. Python may give back
5147 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Issue #2045: Fix an infinite recursion triggered when printing a
5150 subclass of collections.defaultdict, if its default_factory is set
5151 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005152
Christian Heimesf75dbef2008-02-08 00:11:31 +00005153- Fixed a minor memory leak in dictobject.c. The content of the free
5154 list was not freed on interpreter shutdown.
5155
Georg Brandl21e99f42010-03-07 15:23:59 +00005156- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005157 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005158
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5160 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005161 to compact the internal free lists of pre-allocted ints and floats.
5162
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5164 calls. Python expected the return type int but the fork familie
5165 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005166
Georg Brandl3ee81df2008-05-17 18:14:43 +00005167- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5168 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5171 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5174 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005175
Georg Brandl3ee81df2008-05-17 18:14:43 +00005176- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5177 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005178
Georg Brandl3ee81df2008-05-17 18:14:43 +00005179- Patch #1473257: generator objects gain a gi_code attribute. This is
5180 the same object as the func_code attribute of the function that
5181 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005182
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Issue #1920: "while 0" statements were completely removed by the
5184 compiler, even in the presence of an "else" clause, which is
5185 supposed to be run when the condition is false. Now the compiler
5186 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005187
Guido van Rossumeead05f2008-01-24 18:21:02 +00005188- A few crashers fixed: weakref_in_del.py (issue #1377858);
5189 loosing_dict_ref.py (issue #1303614, test67.py);
5190 borrowed_ref_[34].py (not in tracker).
5191
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005192- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005193 suppressed while an extension is loaded by calling SetErrorMode in
5194 dynload_win.c. The error is still reported properly.
5195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005197 several extension methods and modules do not work without unicode
5198 support.
5199
Georg Brandl26543b12008-01-21 18:36:51 +00005200- Issue #1882: when compiling code from a string, encoding cookies in the
5201 second line of code were not always recognized correctly.
5202
Georg Brandl14404b62008-01-19 19:27:05 +00005203- Issue #1679: "0x" was taken as a valid integer literal.
5204
Georg Brandl6caad7d2008-01-26 14:19:22 +00005205- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005206 added.
5207
Christian Heimesc94e2b52008-01-14 04:13:37 +00005208- sys.float_info / PyFloat_GetInfo: The floating point information
5209 object was converted from a dict to a specialized structseq object.
5210
Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- Patch #1816: Added sys.flags structseq. It exposes the status of
5212 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Objects/structseq.c: Implemented new structseq representation. The
5215 patch makes structseqs (e.g. the return value of os.stat) more
5216 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005217
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Patch #1700288: added a type attribute cache that caches method
5219 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005220
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005221- Bug #1776: __import__() no longer accepts filenames on any platform.
5222 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005223
Georg Brandlaed6c662008-01-07 17:25:53 +00005224- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5227 envvar and sys.dont_write_bytecode attribute. All these can be set
5228 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005229
Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Improve some exception messages when Windows fails to load an
5231 extension module. Now we get for example '%1 is not a valid Win32
5232 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005233
Georg Brandl3ee81df2008-05-17 18:14:43 +00005234- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005236- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5237 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005238
Christian Heimes0a8143f2007-12-18 23:22:54 +00005239- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240 and INF. float("nan"), float("inf") and float("-inf") now work on
5241 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005242
Georg Brandl3ee81df2008-05-17 18:14:43 +00005243- Compiler now generates simpler and faster code for dictionary
5244 literals. The oparg for BUILD_MAP now indicates an estimated
5245 dictionary size. There is a new opcode, STORE_MAP, for adding
5246 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005247
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005253- Issue #1538: Avoid copying string in split/rsplit if the split char
5254 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005255
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005256- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005257 SystemError.
5258
Nick Coghlanef01d822007-12-03 12:55:17 +00005259- PEP 366: Allow explicit relative imports when executing modules
5260 inside packages with the -m switch via a new module level
5261 __package__ attribute.
5262
Georg Brandl3ee81df2008-05-17 18:14:43 +00005263- Issue #1402: Fix a crash on exit, when another thread is still
5264 running, and if the deallocation of its frames somehow calls the
5265 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005266

5276 file can now be directly executed by passing their name to the
5277 interpreter. The directory/zipfile is automatically inserted as the
5278 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005279
Georg Brandl3ee81df2008-05-17 18:14:43 +00005280- Issue #1265: Fix a problem with sys.settrace, if the tracing
5281 function uses a generator expression when at the same time the
5282 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005283
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005284- sets and frozensets now have an isdisjoint() method.
5285
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005286- optimize the performance of builtin.sum().
5287
Neal Norwitz44f326e2007-10-05 05:29:17 +00005288- Fix warnings found by the new version of the Coverity checker.
5289
Georg Brandl21e99f42010-03-07 15:23:59 +00005290- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005291 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5292 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005293
Georg Brandl3ee81df2008-05-17 18:14:43 +00005294- Issue #1686386: Tuple's tp_repr did not take into account the
5295 possibility of having a self-referential tuple, which is possible
5296 from C code. Nor did object's tp_str consider that a type's tp_str
5297 could do something that could lead to an inifinite recursion.
5298 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5299 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005300
Georg Brandl3ee81df2008-05-17 18:14:43 +00005301- Issue #1164: It was possible to trigger deadlock when using the
5302 'print' statement to write to a file since the GIL was not released
5303 as needed. Now PyObject_Print() does the right thing along with
5304 various tp_print implementations of the built-in types and those in
5305 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005306
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Issue #1147: Exceptions were directly allowing string exceptions in
5308 their throw() method even though string exceptions no longer
5309 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005310

Brett Cannon1e534b52007-09-07 04:18:30 +00005314- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005315 PyObject_Call() never calling back out to Python code to trigger
5316 recursion depth updates/checks. Required the creation of a static
5317 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005335 __*__ attributes. (Some already existed, e.g., __doc__ and
5336 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005337
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005338- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00005345 "except E as target:". This is to provide forwards compatibility
5346 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005347
Brett Cannon229cee22007-05-05 01:34:02 +00005348- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005353- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005354 setting a plain string, ie don't expand to single letter identifiers.
5355
Raymond Hettinger13936692007-04-11 18:40:58 +00005356- Request #1191699: Slices can now be pickled.

5366
Guido van Rossum143b5642007-03-23 04:58:42 +00005367- Bug #1683368: The object.__init__() and object.__new__() methods are
5368 now stricter in rejecting excess arguments. The only time when
5369 either allows excess arguments is when it is not overridden and the
5370 other one is. For backwards compatibility, when both are
5371 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005372 warning later). Also, type.__init__() insists on the same signature
5373 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005374
Georg Brandl3ee81df2008-05-17 18:14:43 +00005375- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5376 object to complex using its __complex__() method before falling back
5377 to the __float__() method. Therefore, the functions in the cmath
5378 module now can operate on objects that define a __complex__()
5379 method.

5396
Georg Brandl7b9c5552007-03-12 14:30:05 +00005397- Bug #1678647: write a newline after printing an exception in any
5398 case, even when converting the value to a string failed.
5399
Georg Brandl871f1bc2007-03-12 13:17:36 +00005400- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401 its argument, if it exists. If not, it will work like before. This
5402 allows customizing the output of dir() in the presence of a
5403 __getattr__().

5413 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005414
Georg Brandlaa2321b2007-03-07 00:40:28 +00005415- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416 makes the filenames the warning module prints much more sensible
5417 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005418

Georg Brandl0fca97a2007-03-05 22:28:08 +00005430- Patch #1674228: when assigning a slice (old-style), check for the
5431 sq_ass_slice instead of the sq_slice slot.
5432
Georg Brandl3ee81df2008-05-17 18:14:43 +00005433- When printing an unraisable error, don't print exceptions. before

6061 accepted in TestSuite.addTest(). This should cause no
6062 incompatibility since it never made sense with ordinary subclasses
6063 -- the failure just occurred later, with a more cumbersome
6064 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006345- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6346 with RFC 3207 and forgets any knowledge obtained from the server not
6347 obtained from the TLS negotiation itself. Patch contributed by Bill
6348 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006349
Georg Brandl3ee81df2008-05-17 18:14:43 +00006350- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006351 that the SMTP.starttls() caller no longer needs to call ehlo()
6352 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353 does not claim to support starttls. Adds the
6354 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6435 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6436 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006453 time so that opening a database previously created with the DB_DUP
6454 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6455 opens. Specifically: dictionary assignment to a DB object will
6456 replace all values for a given key when the database allows
6457 duplicate values. DB users should use DB.put(k, v) when they want
6458 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006459

6465 characters with ASCII value less than 32. Also, it correctly quotes
6466 dots only if they occur on a single line, as opposed to the previous
6467 behavior of quoting dots if they are the second character of any
6468 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006785- Makefile.pre.in(buildbottest): Run an optional script
6786 pybuildbot.identify to include some information about the build
6787 environment.

Neal Norwitz92422fb2006-08-18 03:57:54 +00006790C API
6791-----
6792
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Unified naming convention for free lists and their limits. All free
6794 lists in Object/ are named ``free_list``, the counter ``numfree``
6795 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6796 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006797
Georg Brandl3ee81df2008-05-17 18:14:43 +00006798- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6799 to ``PyTuple_SetItem``, it can be used to populate a brand new
6800 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006801
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006802- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006803
Georg Brandl3ee81df2008-05-17 18:14:43 +00006804- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6805 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6806 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006807
6808- Patch #1720595: add T_BOOL to the range of structmember types.
6809
6810- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6811 ``PyFloat_GetInfo()`` to the float API.
6812
Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6814 of w# format code incorrectly truncated the length to an int, even
6815 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6816 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006817
Georg Brandl3ee81df2008-05-17 18:14:43 +00006818- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6819 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006820
Georg Brandl3ee81df2008-05-17 18:14:43 +00006821- PEP 3123: Provide forward compatibility with Python 3.0, while
6822 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6823 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6826 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006827
6828- Patch #1733960: Allow T_LONGLONG to accept ints.
6829
6830- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6831
Christian Heimes000a0742008-01-03 22:16:32 +00006832- Added a new API function ``PyImport_ImportModuleNoBlock``.
6833
Georg Brandl6caad7d2008-01-26 14:19:22 +00006834- Bug #1637022: Prefix AST symbols with _Py_.
6835
6836- Fix some leftovers from the conversion from int to Py_ssize_t
6837 (relevant to strings and sequences of more than 2**31 items).
6838
6839- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6840 outside of pystate.c and should not be necessary.
6841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6843 absolute imports. In earlier versions they might have used relative
6844 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006845
Georg Brandl3ee81df2008-05-17 18:14:43 +00006846- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6847 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6850 macro so it can be used as an expression.

6855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6857 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6858 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6859 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006860
Georg Brandl3ee81df2008-05-17 18:14:43 +00006861- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6862 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006874- Removed the macfs module. It had been deprecated since Python 2.5.
6875 This lead to the deprecation of macostools.touched() as it relied
6876 solely on macfs and was a no-op under OS X.
