311 handles non-blocking readinto() returning None correctly.
312
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000313- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
314 SSLSocket.sendto() to match the corresponding socket methods. Also,
315 fix various SSLSocket methods to raise socket.error rather than an
316 unhelpful TypeError when called on an unconnected socket. Original patch
317 by Andrew Bennetts.

326
Raymond Hettinger20397532010-09-12 02:11:45 +0000327- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
328 This prevents user-created self-referencing ordered dictionaries from
329 becoming permanently uncollectable GC garbage. The downside is that
330 removing __del__ means that the internal doubly-linked list has to wait for
331 GC collection rather than freeing memory immediately when the refcnt drops
332 to zero.
333

340 to fetch the original errno, or to filter timeout errors. Now the
341 original error is re-raised.
342

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

805 objects. (1) The comparison could incorrectly return True in some cases
806 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

949 non-float non-integer argument is now converted to an integer (if possible)

Georg Brandlfee0f442010-05-22 21:26:21 +00001150- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001151 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1152 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1153 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1173Core and Builtins
1174-----------------
1175
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001176- Issue #7301: Add environment variable $PYTHONWARNINGS.
1177
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001178- Issue #8329: Don't return the same lists from select.select when no fds are
1179 changed.
1180
Georg Brandlfee0f442010-05-22 21:26:21 +00001181- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001182 on 64-bit machines. The shift count for either left or right shift is
1183 permitted to be up to sys.maxsize.
1184
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001185- Ensure that tokenization of identifiers is not affected by locale.
1186
Georg Brandlfee0f442010-05-22 21:26:21 +00001187- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001188
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001189- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1190
Georg Brandlfee0f442010-05-22 21:26:21 +00001191- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1192 with a non-empty format string. This is an effort to future-proof user
1193 code. If a derived class does not currently implement __format__ but later
1194 adds its own __format__, it would most likely break user code that had
1195 supplied a format string. This will be changed to a DeprecationWaring in
1196 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001197
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001198- Issue #8268: Old-style classes (not just instances) now support weak
1199 references.
1200
Georg Brandlfee0f442010-05-22 21:26:21 +00001201- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1202 is set.

Benjamin Peterson96545892010-03-21 20:21:00 +00001206- Issue #6474: Make error message from passing an inadequate number of keyword
1207 arguments to a function correct.
1208
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001209- Issue #8164: Don't allow lambda functions to have a docstring.
1210
Victor Stinner66644262010-03-10 22:30:19 +00001211- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001212 (SIGINT). If an error occurs while importing the site module, the error is
1213 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001214 module.

1222
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001223- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001224 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1225 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001227- Issue #8310: Allow dis to examine new style classes.
1228
Georg Brandlfee0f442010-05-22 21:26:21 +00001229- Issue #8257: The Decimal construct now accepts a float instance directly,
1230 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001231
1232 >>> Decimal(1.1)
1233 Decimal('1.100000000000000088817841970012523233890533447265625')
1234
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001235- collections.Counter() now supports a subtract() method.
1236
Georg Brandlfee0f442010-05-22 21:26:21 +00001237- The functools module now has a total_ordering() class decorator to simplify
1238 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001239
Georg Brandlfee0f442010-05-22 21:26:21 +00001240- The functools module also adds cmp_to_key() as a tool to transition old-style
1241 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001242
Georg Brandlfee0f442010-05-22 21:26:21 +00001243- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1244 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001245
Georg Brandlfee0f442010-05-22 21:26:21 +00001246- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1247 InvalidOperation instead of returning False. (Comparisons involving a quiet
1248 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1249 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001250
Georg Brandlfee0f442010-05-22 21:26:21 +00001251- Issue #2531: Comparison operations between floats and Decimal instances now
1252 return a result based on the numeric values of the operands; previously they
1253 returned an arbitrary result based on the relative ordering of id(float) and
1254 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001255
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001256- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001257 argument `-` which tells it to read files to compile from stdin. Each line is
1258 read on demand and the named file is compiled immediately. (Original patch by
1259 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001260
Georg Brandlfee0f442010-05-22 21:26:21 +00001261- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1262 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00001263
Florent Xicluna58b65662010-03-30 16:29:03 +00001264- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1265 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001266 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001267
Georg Brandlfee0f442010-05-22 21:26:21 +00001268- Comparisons using one of <, <=, >, >= between a complex instance and a
1269 Fractions instance now raise TypeError instead of returning True/False. This
1270 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1271 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001272
Michael Foorde6410c52010-03-29 20:04:23 +00001273- Addition of ``WeakSet`` to the ``weakref`` module.

1281
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001282- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001283 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1284 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001285
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001286- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1287 deprecated.
1288
Georg Brandlfee0f442010-05-22 21:26:21 +00001289- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1290 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001291

1296 existing at the same time, causing a Unicode error when configuration code
1297 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001298
Georg Brandlfee0f442010-05-22 21:26:21 +00001299- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1300 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001301
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001302- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1303 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1304 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001305
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001306- Issue #8179: Fix macpath.realpath() on a non-existing path.

1312 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00001313
Matthias Klose8b411682010-03-16 10:48:52 +00001314- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1315 with Tcl/Tk-8.5.

1320 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00001321
Georg Brandlfee0f442010-05-22 21:26:21 +00001322- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
1323 to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +00001324 program name.
Victor Stinner75227342010-03-12 14:30:26 +00001325
Vinay Sajipecfa08f2010-03-12 09:16:10 +00001326- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001327 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1328 log file to compute the next rollover time. If the log file does not exist,
1329 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001330
Georg Brandlba83f822010-03-14 09:50:54 +00001331- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

1338
Georg Brandlba83f822010-03-14 09:50:54 +00001339- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1340 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1341 This is a behavior change, so email's minor version number is now bumped, to
1342 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001343

1361
Jesus Cea6557aac2010-03-22 14:22:26 +00001362- Issue #8156: bsddb module updated to version 4.8.4.
Georg Brandlfee0f442010-05-22 21:26:21 +00001363 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4. This update drops
1364 support for Berkeley DB 4.0, and adds support for 4.8.

1369
Mark Dickinson4846a8e2010-04-03 14:05:10 +00001370- Issue #8300: When passing a non-integer argument to struct.pack with any
1371 integer format code, struct.pack first attempts to convert the non-integer
1372 using its __index__ method. If that method is non-existent or raises
1373 TypeError it goes on to try the __int__ method, as described below.
1374
Georg Brandlba83f822010-03-14 09:50:54 +00001375- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1376 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1377 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001378 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1379 inconsistent: __int__ was used for some integer codes but not for others, and
1380 the set of integer codes for which it was used differed between native packing
1381 and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +00001382
Georg Brandlfee0f442010-05-22 21:26:21 +00001383- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
1384 the return value of QueryReflectionKey.

1796 These functions and methods now raise TypeError instead. The majority of the
1797 effects of this change are in the extension modules, but some core functions
1798 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1799 and many unicode/str methods.

1815 internal representation of a long.

1823
Georg Brandlba83f822010-03-14 09:50:54 +00001824 These executables now work properly with the arch(1) command: ``arch -ppc

1969 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00001982- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1983 decimal string that's guaranteed to round back to x under correct rounding
1984 (with round-half-to-even rounding mode). Previously it gave a string based on
1985 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1986 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1987 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001988
Georg Brandlba83f822010-03-14 09:50:54 +00001989- Issue #7117: On almost all platforms: float-to-string and string-to-float
1990 conversions within Python are now correctly rounded. Places these conversions
1991 occur include: str for floats and complex numbers; the float and complex
1992 constructors; old-style and new-style numeric formatting; serialization and
1993 deserialization of floats and complex numbers using marshal, pickle and json;
1994 parsing of float and imaginary literals in Python code; Decimal-to-float
1995 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001996
Georg Brandlba83f822010-03-14 09:50:54 +00001997 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1998 providing correctly-rounded strtod and dtoa C functions. This code is
1999 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2000 the C compiler. There may be a small number of platforms on which correct
2001 operation of this code cannot be guaranteed, so the code is not used: notably,
2002 this applies to platforms where the C double format is not IEEE 754 binary64,
2003 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2004 and Python's configure script is unable to determine how to change the FPU
2005 precision. On these platforms conversions use the platform strtod and dtoa,
2006 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002008- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2009 uses the correctly-rounded string <-> float conversions described above (when
2010 available), and so produces correctly rounded results that will display nicely
2011 under the float repr. There are two related small changes: (1) round now
2012 accepts any class with an ``__index__()`` method for its second argument (but
2013 no longer accepts floats for the second argument), and (2) an excessively
2014 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2015 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002157
Georg Brandlba83f822010-03-14 09:50:54 +00002158 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2159 (2) parsing of strings representing infinities and nans was locale aware; and
2160 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002161
Georg Brandlba83f822010-03-14 09:50:54 +00002162- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2163 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2164 but with at least one decimal point and with a default precision
2165 of 12. Previously, the behavior the same but with a default precision of 6.
2166 This more closely matches ``str()``, and reduces surprises when adding
2167 alignment flags to the empty presentation type. This also affects the new
2168 complex.__format__ in the same way.
2169
2170- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2171 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002233 untrackable objects are not tracked by the garbage collector. This can reduce

2242 internal representation of integers, for performance reasons. Base 2**30 is
2243 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00002331- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002332 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002333
Skip Montanarof205c132008-12-23 03:30:15 +00002334- Added test case to ensure attempts to read from a file opened for writing
2335 fail.
2336
Georg Brandlba83f822010-03-14 09:50:54 +00002337- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2338 elapsed times, not only when some objects are uncollectable/unreachable.
2339 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00002351- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2352 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2353 instances. On a typical machine this saves 3 bytes of memory (on average) per
2354 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002356- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2357 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2358 instead of throwing a MemoryError.
2359
Georg Brandlba83f822010-03-14 09:50:54 +00002360- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2361 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00002363- Issue #4367: Python would segfault during compiling when the unicodedata
2364 module couldn't be imported and \N escapes were present.
2365
Georg Brandlba83f822010-03-14 09:50:54 +00002366- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2367 file objects with closefd=False. The file descriptor is still kept open but
2368 the file object behaves like a closed file. The ``FileIO`` object also got a
2369 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002371- Issue #4348: Some bytearray methods returned that didn't cause any change to
2372 the bytearray, returned the same bytearray instead of a copy.
2373
Georg Brandlba83f822010-03-14 09:50:54 +00002374- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002386- Issue #4209: Enabling unicode_literals and the print_function in the same
2387 __future__ import didn't work.
2388
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002389- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002390 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002391
Georg Brandlba83f822010-03-14 09:50:54 +00002392- On windows, ``os.chdir()`` given unicode was not working if
2393 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2394 this code path is really executed because I cannot move to such directory on
2395 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002396
Georg Brandlba83f822010-03-14 09:50:54 +00002397- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2398 element is temporarily replaced with an equivalent frozenset. But the
2399 eventual KeyError would always report the empty ``frozenset()`` as the missing
2400 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002417- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2418 returned them on 64bit platforms.
2419
Walter Dörwalded960ac2009-05-03 22:36:33 +00002420- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2421 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2422 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2423 of using the replace error handler in PyUnicode_DecodeUTF8().
2424
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002425- Issue #3739: The unicode-internal encoder now reports the number of characters
2426 consumed like any other encoder (instead of the number of bytes).
2427
Georg Brandlba83f822010-03-14 09:50:54 +00002428- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2429 allocator will be automatically disabled when running under Valgrind. This
2430 gives improved memory leak detection when running under Valgrind, while taking
2431 advantage of pymalloc at other times.

3682 import both normal and optimised versions of modules. test_heapq and
3683 test_warnings have been adjusted to use it, tests for other modules with both
3684 C and Python implementations in the stdlib can be adjusted to use it over
3685 time.

3695 support, which does the conversion.

3797
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003798- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3799 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3800 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3801 ``printf`` function, whereas PyString_FromFormat has an independent
3802 implementation and uses "%zd" on all platforms for size_t values.
3803 This makes a difference on win64, where ``printf`` needs "%Id" to display
3804 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003821 was correctly parsed but parsing of subsequent arguments failed.
3822
Vinay Sajip35e3b032008-09-01 14:33:59 +00003823- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003824 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3825 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3826 when given a tuple of classes as second argument, were looking up
3827 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3828 type object.

3972Core and Builtins
3973-----------------
3974
Guido van Rossumf8402962008-08-20 15:01:50 +00003975- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3976 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3977 extensions do not automatically benefit from the class attribute
3978 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3979 to their tp_flags field if they care. This is a backwards
3980 compatibility feature; in 3.0, all types will use the cache by
3981 default.
3982
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003983- Keyword arguments can now follow starred arguments. (``f(a, *args,
3984 keyword=23)`` is now valid syntax.)
3985
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003986- ctypes function pointers that are COM methods have a boolean True
3987 value again.
3988
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003989- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3990 by denying s# to parse objects that have a releasebuffer procedure,
3991 and introducing s*.
3992
Georg Brandl1e13ea92008-08-11 09:07:59 +00003993- Issue #3537: Fix an assertion failure when an empty but presized dict
3994 object was stored in the freelist.
3995
Mark Dickinsonb6467572008-08-04 21:30:09 +00003996- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3997 ValueError consistently across platforms.
3998
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003999- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4000 (64bit Unix, for example), unichr() would truncate its argument and return
4001 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4002
Neal Norwitze7d8be82008-07-31 17:17:14 +00004003- Apply security patches from Apple.
4004
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004005- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4006 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4007
Antoine Pitrou92f82162008-07-25 22:22:08 +00004008- Issue #1819: function calls with several named parameters are now on
4009 average 35% faster (as measured by pybench).
4010
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004011- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4012 the python debugger steps into a class statement: the free variables (local
4013 variables defined in an outer scope) would be deleted from the outer scope.
4014
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004015- Issue #2620: Overflow checking when allocating or reallocating memory
4016 was not always being done properly in some python types and extension
4017 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4018 all been updated to perform better checks and places in the code that
4019 would previously leak memory on the error path when such an allocation
4020 failed have been fixed.

4023-------
4024
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004025- Issue #3612: Added some missing basic types in ctypes.wintypes.
4026
Benjamin Petersone977ad42008-08-20 01:42:01 +00004027- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4028 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4029
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004030- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4031 version reported by these tools does not necessarily follow the python
4032 version numbering scheme, so the module is less strict when parsing it.
4033
Nick Coghlanf70385a2008-08-18 12:42:46 +00004034- Issue #2235: Added Py3k warnings for types which will become unhashable
4035 under the stricter __hash__ inheritance rules in 3.0. Several types
4036 which did not meet the rules for hash invariants and were already
4037 unhashable in 3.0 have now been explicitly flagged as unhashable in
4038 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4039 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4040
Brett Cannon88f801d2008-08-18 00:46:22 +00004041- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4042 imported into the module but exposed as part of the module's API.
4043
Brett Cannon7b96f072008-08-18 00:41:11 +00004044- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4045
Brett Cannon46225e72008-08-18 00:36:52 +00004046- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4047
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004048- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4049
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004050- Issue #3575: Incremental decoder's decode function now takes bytearray
4051 by using 's*' instead of 't#'.
4052
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004053- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004054 fails unicode conversion on 2nd parameter. (windows only)
4055
Georg Brandl222e2082010-08-01 22:27:39 +00004056- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004057 in a redirect.
4058
Brett Cannonabe423e2008-08-16 21:47:07 +00004059- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004060 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004061
Facundo Batistaeb90b782008-08-16 14:44:07 +00004062- Issue #2776: fixed small issue when handling an URL with double slash
4063 after a 302 response in the case of not going through a proxy.
4064
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004065- Issue #2676: in the email package, content-type parsing was hanging on
4066 pathological input because of quadratic or exponential behaviour of a
4067 regular expression.
4068
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004069- Issue #3476: binary buffered reading through the new "io" library is now
4070 thread-safe.
4071
Brett Cannonbf3157b2008-08-14 05:00:03 +00004072- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4073 since mimetools itself is deprecated. Because modules are cached, all
4074 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4075
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004076- Issue #3134: shutil referenced undefined WindowsError symbol.
4077
Robert Schuppenies14646332008-08-10 11:01:53 +00004078- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4079 menu entries were not deleted.
4080
Brett Cannon83e81842008-08-09 23:30:55 +00004081- Copied the implementation of reduce() to _functools.reduce() to have a
4082 version that did not raise a DeprecationWarning under -3.
4083
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004084- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4085 a MemoryError rather than silently stop the iteration.
4086
Guido van Rossum59ce9012008-08-09 14:55:34 +00004087- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4088 to _sre.compile() will now be rejected. This should not affect anybody
4089 since the re.compile() function never generates invalid re-bytecode.
4090
Skip Montanaroa032bf42008-08-08 22:52:51 +00004091- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4092 upon first access it can be automatically initialized from the csv file if
4093 it wasn't initialized during instantiation.
4094
Brett Cannon3aa2a492008-08-06 22:28:09 +00004095- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4096 the reload() built-in has been removed.
4097
Brett Cannon7e30b672008-08-04 21:52:25 +00004098- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004099 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004100 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4101 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4102 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4103 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4104 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004105
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004106- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4107 raised an AttributeError.
4108
Benjamin Peterson01a24322008-07-28 23:35:27 +00004109- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004110 asking for a specific length. This problem only affected files opened
4111 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004112
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004113- Issue #3449: Update decimal module to use most recent specification
4114 (v. 1.68) and tests (v. 2.58) from IBM.
4115
Georg Brandl222e2082010-08-01 22:27:39 +00004116- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004117
Georg Brandl222e2082010-08-01 22:27:39 +00004118- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00004119 on a closed shelf.
4120
Georg Brandlf9efabb2008-07-23 15:16:45 +00004121- Deprecate the "ast" parser function aliases.
4122
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004123- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4124
4125- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4126 invalid arguments.
4127
4128- Issue #3302: Fix several crashes when calling locale's gettext functions
4129 with None arguments.
4130
4131- Issue #3389: Allow resolving dotted names for handlers in logging
4132 configuration files.
4133
4134- Deprecate the sunaudio module for removal in Python 3.0.
4135
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004136- Issue #3394: zipfile.writestr sets external attributes when passed a
4137 file name rather than a ZipInfo instance, so files are extracted with
4138 mode 0600 rather than 000 under Unix.
4139
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004140- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4141 argument in python 2.5, this broke code that subclassed Popen to include its
4142 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4151
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004152- Issue #2235: the C API function PyObject_HashNotImplemented and its
4153 interaction with the tp_hash slot (added in 2.6b2) are now documented
4154
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004155- Issue #643841: The language reference now provides more detailed
4156 coverage of the lookup process for special methods. The disclaimers
4157 regarding lack of coverage of new-style classes have also been
4158 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004166Core and Builtins
4167-----------------
4168
Georg Brandl3e483f62008-07-16 22:57:41 +00004169- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4170 its methods now allow for items objects that can be converted to
4171 an integer using operator.index().
4172
Mark Dickinson64b7e502008-07-16 09:40:03 +00004173- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4174 produced a ValueError instead of giving the correct float.
4175
Eric Smitha5fa5a22008-07-16 00:11:49 +00004176- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4177 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4178
Mark Dickinson7103aa42008-07-15 19:08:33 +00004179- Issue #3008: the float type has a new instance method 'float.hex'
4180 and a new class method 'float.fromhex' to convert floating-point
4181 numbers to and from hexadecimal strings, respectively.
4182
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004183- Issue #2235: __hash__ is once again inherited by default. To allow
4184 collections.Hashable to remain meaningful in the presence of the
4185 default hash implementation (object.__hash__), it is now possible
4186 to explicit block inheritance of hash by setting __hash__=None at
4187 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4188 level.
4189
Nick Coghlanb028f502008-07-13 14:52:36 +00004190- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4191 the parent module cannot be found while performing an absolute import.
4192 This means that an incorrectly defined __package__ attribute will
4193 now only prevent relative imports in that module rather than causing
4194 all imports from that module to fail.
4195
Nick Coghlan14ff9942008-07-08 14:21:42 +00004196- Issue #2517: Allow unicode messages in Exceptions again by correctly
4197 bypassing the instance dictionary when looking up __unicode__ on
4198 new-style classes.
4199
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004200- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4201 set to a custom object whose write() method happens to install
4202 another file in sys.stdout.
4203
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004204- Issue #3088: Corrected a race condition in classes derived from
4205 threading.local: the first member set by a thread could be saved in
4206 another thread's dictionary.
4207
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004208- Issue #3004: Minor change to slice.indices(): the start and stop
4209 arguments are now treated identically, making the behaviour easier
4210 to describe and understand. For example, slice(None, -10,
4211 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4212 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4213 10, -1).
4214
Georg Brandl278fc502008-07-19 12:46:12 +00004215- Issue #3219: Calling a function with repeated keyword arguments,
4216 f(a=2, a=23), would not cause a syntax error. This was a regression
4217 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004218
Georg Brandl278fc502008-07-19 12:46:12 +00004219- Issue #2862: Make int and float freelist management consistent with
4220 other freelists. Changes their CompactFreeList apis into
4221 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004222

4224-------
4225
Thomas Heller57adf222008-08-14 19:10:48 +00004226- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4227 api functions without holding the GIL, which could lead to a fatal
4228 error when they failed.
4229
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004230- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004238- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4239 ForkingPickler.register() to resolve conflict with ctypes.
4240
Vinay Sajip51e65192008-07-18 09:01:10 +00004241- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004242
Thomas Heller880f5292008-07-15 19:39:38 +00004243- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4244 a valid dlerror() message.
4245
Thomas Heller2bad6572008-07-15 17:19:50 +00004246- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4247 incomplete structure was created.
4248
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004249- Issue #3339: dummy_thread.acquire() should not return None.
4250
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004251- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4252
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004253- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004254
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004255- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is

4666 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004667 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004668
4669 This is controlled by the configure argument ``--with-universal-archs``:
4670
4671 - ``--with-universal-archs=all``: install 4-way universal
4672
4673 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4674
4675 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4676
4677 This option should be used in combination with ``--enable-universalsdk=``.
4678
4679 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 +00004729- Issue #1631171: Re-implement the 'warnings' module in C (the
4730 original Python code has been kept as backup). This will allow for
4731 using the 'warning's machinery in such places as the parser where
4732 use of pure Python code is not possible. Both the ``showarning()``
4733 and ``formatwarning()`` gain an optional 'line' argument which is
4734 not called by default for backwards-compatibility reasons. Setting
4735 ``warnings.showwarning()`` to an implementation that lacks support
4736 for the ``line`` argument will raise a DeprecationWarning.

4760
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004761- The getpass module has been improved on Unix. It now uses /dev/tty
4762 by default and uses stderr instead of stdout. A GetPassWarning is
4763 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004764

Georg Brandl3ee81df2008-05-17 18:14:43 +00004778- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004779 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Issue #2550: The approach used by client/server code for obtaining
4800 ports to listen on in network-oriented tests has been refined in an
4801 effort to facilitate running multiple instances of the entire
4802 regression test suite in parallel without issue.
4803 test_support.bind_port() has been fixed such that it will always
4804 return a unique port -- which wasn't always the case with the
4805 previous implementation, especially if socket options had been set
4806 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4807 new implementation of bind_port() will actually raise an exception
4808 if it is passed an AF_INET/SOCK_STREAM socket with either the
4809 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4810 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4811 the socket it's been passed. This currently only applies to
4812 Windows. This option prevents any other sockets from binding to the
4813 host/port we've bound to, thus removing the possibility of the
4814 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4815 when a second SOCK_STREAM socket binds and accepts to a host/port
4816 that's already been bound by another socket. The optional preferred
4817 port parameter to bind_port() has been removed. Under no
4818 circumstances should tests be hard coding ports!
4819
4820 test_support.find_unused_port() has also been introduced, which will
4821 pass a temporary socket object to bind_port() in order to obtain an
4822 unused port. The temporary socket object is then closed and
4823 deleted, and the port is returned. This method should only be used
4824 for obtaining an unused port in order to pass to an external program
4825 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4826 a parameter to a server-oriented class that doesn't give you direct
4827 access to the underlying socket used.
4828
4829 Finally, test_support.HOST has been introduced, which should be used
4830 for the host argument of any relevant socket calls (i.e. bind and
4831 connect).

4833 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

4836 test_asynchat and test_socket_ssl.
4837
Georg Brandl3ee81df2008-05-17 18:14:43 +00004838 It is now possible for multiple instances of the regression test
4839 suite to run in parallel without issue.

5107
Fred Drakea8ee94b2008-03-01 02:45:07 +00005108- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005109 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005110
Georg Brandlad61bc82008-02-23 15:11:18 +00005111- Issue #2067: file.__exit__() now calls subclasses' close() method.
5112
5113- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005114
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005115- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005116 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005117
Eric Smitha73fbe72008-02-23 03:09:44 +00005118- Added the future_builtins module, which contains hex() and oct().
5119 These are the PEP 3127 version of these functions, designed to be
5120 compatible with the hex() and oct() builtins from Python 3.0. They
5121 differ slightly in their output formats from the existing, unchanged
5122 Python 2.6 builtins. The expected usage of the future_builtins
5123 module is:
5124 from future_builtins import hex, oct
5125
Eric Smith7ef40bf2008-02-20 23:34:22 +00005126- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5127 exponents for exponents with absolute value < 100. Follows C99
5128 standard. This is a change on Windows, which would use 3 digits.
5129 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5130 so that any alterations it does to the resulting string will be
5131 available in stringlib/formatter.h (for float.__format__).
5132
Eric Smith5a3c1352008-02-19 13:21:56 +00005133- Implemented PEP 3101, Advanced String Formatting. This adds a new
5134 builtin format(); a format() method for str and unicode; a
5135 __format__() method to object, str, unicode, int, long, float, and
5136 datetime; the class string.Formatter; and the C API
5137 PyObject_Format().
5138
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Fixed several potential crashes, all caused by specially crafted
5140 __del__ methods exploiting objects in temporarily inconsistent
5141 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005142
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005143- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144 prevent a possible crash: an Abstract Base Class would try to access
5145 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- Fixed repr() and str() of complex numbers with infinity or nan as
5148 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005149
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150- Clear all free lists during a gc.collect() of the highest generation
5151 in order to allow pymalloc to free more arenas. Python may give back
5152 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005153
Georg Brandl3ee81df2008-05-17 18:14:43 +00005154- Issue #2045: Fix an infinite recursion triggered when printing a
5155 subclass of collections.defaultdict, if its default_factory is set
5156 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005157
Christian Heimesf75dbef2008-02-08 00:11:31 +00005158- Fixed a minor memory leak in dictobject.c. The content of the free
5159 list was not freed on interpreter shutdown.
5160
Georg Brandl21e99f42010-03-07 15:23:59 +00005161- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005163
Georg Brandl3ee81df2008-05-17 18:14:43 +00005164- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5165 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005166 to compact the internal free lists of pre-allocted ints and floats.
5167
Georg Brandl3ee81df2008-05-17 18:14:43 +00005168- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5169 calls. Python expected the return type int but the fork familie
5170 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005171
Georg Brandl3ee81df2008-05-17 18:14:43 +00005172- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5173 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005174
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5176 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005177
Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5179 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005180
Georg Brandl3ee81df2008-05-17 18:14:43 +00005181- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5182 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005183
Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Patch #1473257: generator objects gain a gi_code attribute. This is
5185 the same object as the func_code attribute of the function that
5186 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Issue #1920: "while 0" statements were completely removed by the
5189 compiler, even in the presence of an "else" clause, which is
5190 supposed to be run when the condition is false. Now the compiler
5191 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005192
Guido van Rossumeead05f2008-01-24 18:21:02 +00005193- A few crashers fixed: weakref_in_del.py (issue #1377858);
5194 loosing_dict_ref.py (issue #1303614, test67.py);
5195 borrowed_ref_[34].py (not in tracker).
5196
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005197- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005198 suppressed while an extension is loaded by calling SetErrorMode in
5199 dynload_win.c. The error is still reported properly.
5200
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005202 several extension methods and modules do not work without unicode
5203 support.
5204
Georg Brandl26543b12008-01-21 18:36:51 +00005205- Issue #1882: when compiling code from a string, encoding cookies in the
5206 second line of code were not always recognized correctly.
5207
Georg Brandl14404b62008-01-19 19:27:05 +00005208- Issue #1679: "0x" was taken as a valid integer literal.
5209
Georg Brandl6caad7d2008-01-26 14:19:22 +00005210- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005211 added.
5212
Christian Heimesc94e2b52008-01-14 04:13:37 +00005213- sys.float_info / PyFloat_GetInfo: The floating point information
5214 object was converted from a dict to a specialized structseq object.
5215
Georg Brandl3ee81df2008-05-17 18:14:43 +00005216- Patch #1816: Added sys.flags structseq. It exposes the status of
5217 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005218
Georg Brandl3ee81df2008-05-17 18:14:43 +00005219- Objects/structseq.c: Implemented new structseq representation. The
5220 patch makes structseqs (e.g. the return value of os.stat) more
5221 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005222
Georg Brandl3ee81df2008-05-17 18:14:43 +00005223- Patch #1700288: added a type attribute cache that caches method
5224 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005225
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005226- Bug #1776: __import__() no longer accepts filenames on any platform.
5227 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005228
Georg Brandlaed6c662008-01-07 17:25:53 +00005229- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5230
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5232 envvar and sys.dont_write_bytecode attribute. All these can be set
5233 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005234
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235- Improve some exception messages when Windows fails to load an
5236 extension module. Now we get for example '%1 is not a valid Win32
5237 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005238
Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5242 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005243
Christian Heimes0a8143f2007-12-18 23:22:54 +00005244- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245 and INF. float("nan"), float("inf") and float("-inf") now work on
5246 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005247
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248- Compiler now generates simpler and faster code for dictionary
5249 literals. The oparg for BUILD_MAP now indicates an estimated
5250 dictionary size. There is a new opcode, STORE_MAP, for adding
5251 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005252
Georg Brandl3ee81df2008-05-17 18:14:43 +00005253- Issue #1638: %zd configure test fails on Linux.

5269 running, and if the deallocation of its frames somehow calls the
5270 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005271

5281 file can now be directly executed by passing their name to the
5282 interpreter. The directory/zipfile is automatically inserted as the
5283 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005284
Georg Brandl3ee81df2008-05-17 18:14:43 +00005285- Issue #1265: Fix a problem with sys.settrace, if the tracing
5286 function uses a generator expression when at the same time the
5287 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005288
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005289- sets and frozensets now have an isdisjoint() method.
5290
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005291- optimize the performance of builtin.sum().
5292
Neal Norwitz44f326e2007-10-05 05:29:17 +00005293- Fix warnings found by the new version of the Coverity checker.
5294
Georg Brandl21e99f42010-03-07 15:23:59 +00005295- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005296 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5297 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005298
Georg Brandl3ee81df2008-05-17 18:14:43 +00005299- Issue #1686386: Tuple's tp_repr did not take into account the
5300 possibility of having a self-referential tuple, which is possible
5301 from C code. Nor did object's tp_str consider that a type's tp_str
5302 could do something that could lead to an inifinite recursion.
5303 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5304 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005305
Georg Brandl3ee81df2008-05-17 18:14:43 +00005306- Issue #1164: It was possible to trigger deadlock when using the
5307 'print' statement to write to a file since the GIL was not released
5308 as needed. Now PyObject_Print() does the right thing along with
5309 various tp_print implementations of the built-in types and those in
5310 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005312- Issue #1147: Exceptions were directly allowing string exceptions in
5313 their throw() method even though string exceptions no longer
5314 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005315
Georg Brandl3ee81df2008-05-17 18:14:43 +00005316- Issue #1096: Prevent a segfault from getting the repr of a very
5317 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005318
Brett Cannon1e534b52007-09-07 04:18:30 +00005319- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005320 PyObject_Call() never calling back out to Python code to trigger
5321 recursion depth updates/checks. Required the creation of a static
5322 RuntimeError instance in case normalizing an exception put the
5323 recursion check value past its limit. Fixes crashers
5324 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005339- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005340 __*__ attributes. (Some already existed, e.g., __doc__ and
5341 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005342
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005343- Add -3 option to the interpreter to warn about features that are
5344 deprecated and will be changed/removed in Python 3.0.
5345
Georg Brandl2134e752007-05-21 20:34:16 +00005346- Patch #1686487: you can now pass any mapping after '**' in function
5347 calls.
5348
Collin Winter62903052007-05-18 23:11:24 +00005349- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005350 "except E as target:". This is to provide forwards compatibility
5351 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005352
Brett Cannon229cee22007-05-05 01:34:02 +00005353- Deprecate BaseException.message as per PEP 352.
5354
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005356 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005357
Vinay Sajip8549ce32007-05-06 17:53:37 +00005358- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005359 setting a plain string, ie don't expand to single letter identifiers.
5360
Raymond Hettinger13936692007-04-11 18:40:58 +00005361- Request #1191699: Slices can now be pickled.
5362
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005363- Request #1193128: str.translate() now allows a None argument for
5364 translations that only remove characters without re-mapping the
5365 remaining characters.
5366
Georg Brandl5cb76c12007-03-21 09:00:39 +00005367- Patch #1682205: a TypeError while unpacking an iterable is no longer
5368 masked by a generic one with the message "unpack non-sequence".
5369
Neal Norwitzaa754b72007-03-21 06:39:48 +00005370- Remove unused file Python/fmod.c.
5371
Guido van Rossum143b5642007-03-23 04:58:42 +00005372- Bug #1683368: The object.__init__() and object.__new__() methods are
5373 now stricter in rejecting excess arguments. The only time when
5374 either allows excess arguments is when it is not overridden and the
5375 other one is. For backwards compatibility, when both are
5376 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005377 warning later). Also, type.__init__() insists on the same signature
5378 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005379
Georg Brandl3ee81df2008-05-17 18:14:43 +00005380- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5381 object to complex using its __complex__() method before falling back
5382 to the __float__() method. Therefore, the functions in the cmath
5383 module now can operate on objects that define a __complex__()
5384 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005385
Georg Brandl3ee81df2008-05-17 18:14:43 +00005386- Patch #1623563: allow __class__ assignment for classes with
5387 __slots__. The old and the new class are still required to have the
5388 same slot names.

5394 ``object.__reduce_ex__()`` is called with an object that is faking
5395 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005396
Georg Brandl3ee81df2008-05-17 18:14:43 +00005397- Patch #1680015: Don't modify __slots__ tuple if it contains an

5401
Georg Brandl7b9c5552007-03-12 14:30:05 +00005402- Bug #1678647: write a newline after printing an exception in any
5403 case, even when converting the value to a string failed.
5404
Georg Brandl871f1bc2007-03-12 13:17:36 +00005405- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406 its argument, if it exists. If not, it will work like before. This
5407 allows customizing the output of dir() in the presence of a
5408 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005409
Collin Winter276887b2007-03-12 16:11:39 +00005410- Patch #922167: Python no longer segfaults when faced with infinitely
5411 self-recursive reload() calls (as reported by bug #742342).
5412

5417 parthensized forms. This means complex(repr(x)) now works instead of
5418 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005419
Georg Brandlaa2321b2007-03-07 00:40:28 +00005420- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005421 makes the filenames the warning module prints much more sensible
5422 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005423
Georg Brandl49aafc92007-03-07 00:34:46 +00005424- Variant of patch #697613: don't exit the interpreter on a SystemExit
5425 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005426 variable is given, but break into the interactive interpreter just
5427 like on other exceptions or normal program exit.

5433 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005434
Georg Brandl0fca97a2007-03-05 22:28:08 +00005435- Patch #1674228: when assigning a slice (old-style), check for the
5436 sq_ass_slice instead of the sq_slice slot.
5437
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438- When printing an unraisable error, don't print exceptions. before
5439 the name. This duplicates the behavior whening normally printing
5440 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005448- Bug #1377858: Fix the segfaulting of the interpreter when an object
5449 created a weakref on itself during a __del__ call for new-style
5450 classes (classic classes still have the bug).

6049 Python would crash instead of raising an error.
6050
Thomas Hellerc2f77252007-03-09 19:21:28 +00006051- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
6052 returned string up to the first NUL character.

6063
Georg Brandl3ee81df2008-05-17 18:14:43 +00006064- unittest now verifies more of its assumptions. In particular,
6065 TestCase and TestSuite subclasses (not instances) are no longer
6066 accepted in TestSuite.addTest(). This should cause no
6067 incompatibility since it never made sense with ordinary subclasses
6068 -- the failure just occurred later, with a more cumbersome
6069 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006356 that the SMTP.starttls() caller no longer needs to call ehlo()
6357 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006358 does not claim to support starttls. Adds the
6359 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006458 time so that opening a database previously created with the DB_DUP
6459 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6460 opens. Specifically: dictionary assignment to a DB object will
6461 replace all values for a given key when the database allows
6462 duplicate values. DB users should use DB.put(k, v) when they want
6463 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006464

6470 characters with ASCII value less than 32. Also, it correctly quotes
6471 dots only if they occur on a single line, as opposed to the previous
6472 behavior of quoting dots if they are the second character of any
6473 line.

6796-----
6797
Georg Brandl3ee81df2008-05-17 18:14:43 +00006798- Unified naming convention for free lists and their limits. All free
6799 lists in Object/ are named ``free_list``, the counter ``numfree``
6800 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6801 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6804 to ``PyTuple_SetItem``, it can be used to populate a brand new
6805 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006806
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006807- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006809- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6810 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6811 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006812
6813- Patch #1720595: add T_BOOL to the range of structmember types.
6814
6815- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6816 ``PyFloat_GetInfo()`` to the float API.
6817
Georg Brandl3ee81df2008-05-17 18:14:43 +00006818- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6819 of w# format code incorrectly truncated the length to an int, even
6820 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6821 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006822
Georg Brandl3ee81df2008-05-17 18:14:43 +00006823- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6824 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006825
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826- PEP 3123: Provide forward compatibility with Python 3.0, while
6827 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6828 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006829
Georg Brandl3ee81df2008-05-17 18:14:43 +00006830- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6831 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006832
6833- Patch #1733960: Allow T_LONGLONG to accept ints.
6834
6835- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6836
Christian Heimes000a0742008-01-03 22:16:32 +00006837- Added a new API function ``PyImport_ImportModuleNoBlock``.

6840
6841- Fix some leftovers from the conversion from int to Py_ssize_t
6842 (relevant to strings and sequences of more than 2**31 items).
6843
6844- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6845 outside of pystate.c and should not be necessary.
6846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6848 absolute imports. In earlier versions they might have used relative
6849 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006850
Georg Brandl3ee81df2008-05-17 18:14:43 +00006851- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6852 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006853
Georg Brandl3ee81df2008-05-17 18:14:43 +00006854- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6855 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006861- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6862 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6863 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6864 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006865
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006879- Removed the macfs module. It had been deprecated since Python 2.5.
6880 This lead to the deprecation of macostools.touched() as it relied
6881 solely on macfs and was a no-op under OS X.
