333 SSLSocket.sendto() to match the corresponding socket methods. Also,
334 fix various SSLSocket methods to raise socket.error rather than an

336 by Andrew Bennetts.

345
Raymond Hettinger20397532010-09-12 02:11:45 +0000346- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
347 This prevents user-created self-referencing ordered dictionaries from
348 becoming permanently uncollectable GC garbage. The downside is that
349 removing __del__ means that the internal doubly-linked list has to wait for
350 GC collection rather than freeing memory immediately when the refcnt drops
351 to zero.

359 to fetch the original errno, or to filter timeout errors. Now the
360 original error is re-raised.

383 character years even if the message contains RFC822 two character years.
384
Daniel Stutzbach91287322010-08-24 21:09:30 +0000385- Issue #8750: Fixed MutableSet's methods to correctly handle

1192Core and Builtins
1193-----------------
1194
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001195- Issue #7301: Add environment variable $PYTHONWARNINGS.
1196
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001197- Issue #8329: Don't return the same lists from select.select when no fds are
1198 changed.
1199
Georg Brandlfee0f442010-05-22 21:26:21 +00001200- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001201 on 64-bit machines. The shift count for either left or right shift is
1202 permitted to be up to sys.maxsize.
1203
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001204- Ensure that tokenization of identifiers is not affected by locale.
1205
Georg Brandlfee0f442010-05-22 21:26:21 +00001206- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

1209
Georg Brandlfee0f442010-05-22 21:26:21 +00001210- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1211 with a non-empty format string. This is an effort to future-proof user
1212 code. If a derived class does not currently implement __format__ but later
1213 adds its own __format__, it would most likely break user code that had
1214 supplied a format string. This will be changed to a DeprecationWaring in
1215 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001216
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001217- Issue #8268: Old-style classes (not just instances) now support weak

1247
Georg Brandlfee0f442010-05-22 21:26:21 +00001248- Issue #8257: The Decimal construct now accepts a float instance directly,
1249 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001250
1251 >>> Decimal(1.1)
1252 Decimal('1.100000000000000088817841970012523233890533447265625')
1253
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001254- collections.Counter() now supports a subtract() method.
1255
Georg Brandlfee0f442010-05-22 21:26:21 +00001256- The functools module now has a total_ordering() class decorator to simplify
1257 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001258
Georg Brandlfee0f442010-05-22 21:26:21 +00001259- The functools module also adds cmp_to_key() as a tool to transition old-style
1260 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001261
Georg Brandlfee0f442010-05-22 21:26:21 +00001262- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1263 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00001265- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1266 InvalidOperation instead of returning False. (Comparisons involving a quiet
1267 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1268 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001269
Georg Brandlfee0f442010-05-22 21:26:21 +00001270- Issue #2531: Comparison operations between floats and Decimal instances now
1271 return a result based on the numeric values of the operands; previously they
1272 returned an arbitrary result based on the relative ordering of id(float) and
1273 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001274
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001275- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001276 argument `-` which tells it to read files to compile from stdin. Each line is
1277 read on demand and the named file is compiled immediately. (Original patch by
1278 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001279
Georg Brandlfee0f442010-05-22 21:26:21 +00001280- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001283- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1284 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001285 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001286
Georg Brandlfee0f442010-05-22 21:26:21 +00001287- Comparisons using one of <, <=, >, >= between a complex instance and a
1288 Fractions instance now raise TypeError instead of returning True/False. This
1289 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1290 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001291

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001301- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001302 didn't support chflags() (for example ZFS under FreeBSD). The error is now

1399 the set of integer codes for which it was used differed between native packing
1400 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00001631- Issue #5677: Explicitly forbid write operations on read-only file objects,
1632 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001633 library would return a bogus result; on Solaris, it was possible to crash the
1634 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00001647- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1648 and add the additional members returned in an OSVERSIONINFOEX structure. The
1649 new members are service_pack_major, service_pack_minor, suite_mask, and
1650 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00001652- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1653 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1654 returning NULL. The macro now returns a statically allocated empty string
1655 instead.

1665 strings,
1666 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1667 numeric strings corresponding to subnormal values,
1668 (3) a memory leak for some values large enough to cause overflow, and
1669 (4) a number of flaws that could lead to incorrectly rounded results.

1687 interpreter shutdown.
1688
Georg Brandlba83f822010-03-14 09:50:54 +00001689- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
1690 XML processing instructions and comments. These raw characters are allowed
1691 by the XML specification, and are necessary when outputting e.g. PHP code in
1692 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00001700- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001701 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001702 Also, raise ValueError rather than TypeError when an unknown TIPC address
1703 type is specified. Patch by Brian Curtin.
1704
Vinay Sajip28c382f2010-02-04 18:48:53 +00001705- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001707- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001708 file position when calling `truncate()`. It would previously change the file
1709 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001710 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1711
Georg Brandlba83f822010-03-14 09:50:54 +00001712- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1713 class used to represent files stored inside an archive. The new
1714 implementation is significantly faster and can be wrapped in a
1715 ``io.BufferedReader`` object for more speedups. It also solves an issue
1716 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1717 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00001718
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00001719- Issue #7792: Registering non-classes to ABCs raised an obscure error.
1720
Georg Brandlba83f822010-03-14 09:50:54 +00001721- Removed the deprecated functions ``verify()`` and ``vereq()`` from

1725 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00001726
Georg Brandlba83f822010-03-14 09:50:54 +00001727- Issue #7748: Since unicode values are supported for some metadata options in
1728 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1729 encoded string for them. This ensures that the upload and register commands
1730 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +00001731

1805-----------------
1806
Georg Brandlba83f822010-03-14 09:50:54 +00001807- The ``__complex__()`` method is now looked up on the class of instances to
1808 make it consistent with other special methods.

1812
Mark Dickinson1b34d252010-01-01 17:27:30 +00001813- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001814 DeprecationWarning when passed a float argument where an integer was expected.
1815 These functions and methods now raise TypeError instead. The majority of the
1816 effects of this change are in the extension modules, but some core functions
1817 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1818 and many unicode/str methods.

1842
Georg Brandlba83f822010-03-14 09:50:54 +00001843 These executables now work properly with the arch(1) command: ``arch -ppc
1844 python`` will start a universal binary version of python in PPC mode (unlike
1845 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002001- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2002 decimal string that's guaranteed to round back to x under correct rounding
2003 (with round-half-to-even rounding mode). Previously it gave a string based on
2004 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2005 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2006 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002007
Georg Brandlba83f822010-03-14 09:50:54 +00002008- Issue #7117: On almost all platforms: float-to-string and string-to-float
2009 conversions within Python are now correctly rounded. Places these conversions
2010 occur include: str for floats and complex numbers; the float and complex
2011 constructors; old-style and new-style numeric formatting; serialization and
2012 deserialization of floats and complex numbers using marshal, pickle and json;
2013 parsing of float and imaginary literals in Python code; Decimal-to-float
2014 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002015
Georg Brandlba83f822010-03-14 09:50:54 +00002016 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2017 providing correctly-rounded strtod and dtoa C functions. This code is
2018 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2019 the C compiler. There may be a small number of platforms on which correct
2020 operation of this code cannot be guaranteed, so the code is not used: notably,
2021 this applies to platforms where the C double format is not IEEE 754 binary64,
2022 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2023 and Python's configure script is unable to determine how to change the FPU
2024 precision. On these platforms conversions use the platform strtod and dtoa,
2025 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002027- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2028 uses the correctly-rounded string <-> float conversions described above (when
2029 available), and so produces correctly rounded results that will display nicely
2030 under the float repr. There are two related small changes: (1) round now
2031 accepts any class with an ``__index__()`` method for its second argument (but
2032 no longer accepts floats for the second argument), and (2) an excessively
2033 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2034 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002177 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2178 (2) parsing of strings representing infinities and nans was locale aware; and
2179 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002181- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2182 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2183 but with at least one decimal point and with a default precision
2184 of 12. Previously, the behavior the same but with a default precision of 6.
2185 This more closely matches ``str()``, and reduces surprises when adding
2186 alignment flags to the empty presentation type. This also affects the new
2187 complex.__format__ in the same way.
2188
2189- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

2326
Georg Brandlba83f822010-03-14 09:50:54 +00002327- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2328 existing .py counterpart, override the co_filename attributes of all code
2329 objects if the original filename is obsolete (which can happen if the file has
2330 been renamed, moved, or if it is accessed through different paths). Patch by
2331 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00002335- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
2336 file with `str' filename on Windows.
2337
Antoine Pitrouaa687902009-01-01 14:11:22 +00002338- Issue #3680: Reference cycles created through a dict, set or deque iterator
2339 did not get collected.
2340
Georg Brandlba83f822010-03-14 09:50:54 +00002341- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
2342 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00002343
Benjamin Peterson7af65562008-12-29 17:56:58 +00002344- Issue #4764: With io.open, IOError.filename is set when trying to open a
2345 directory on POSIX systems.
2346
Benjamin Petersonfe231b02008-12-29 17:47:42 +00002347- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2348 systems.
2349
Georg Brandl6425a2f2008-12-28 11:54:53 +00002350- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002351 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002352
Skip Montanarof205c132008-12-23 03:30:15 +00002353- Added test case to ensure attempts to read from a file opened for writing
2354 fail.
2355
Georg Brandlba83f822010-03-14 09:50:54 +00002356- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2357 elapsed times, not only when some objects are uncollectable/unreachable.
2358 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00002359
Mark Dickinson1a707982008-12-17 16:14:37 +00002360- Issue #3439: Add a bit_length method to int and long.
2361
Georg Brandlba83f822010-03-14 09:50:54 +00002362- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original

2366 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002367
Georg Brandlba83f822010-03-14 09:50:54 +00002368- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002369
Georg Brandlba83f822010-03-14 09:50:54 +00002370- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2371 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2372 instances. On a typical machine this saves 3 bytes of memory (on average) per
2373 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002374
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002375- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2376 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2377 instead of throwing a MemoryError.
2378
Georg Brandlba83f822010-03-14 09:50:54 +00002379- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2380 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002381
Benjamin Petersonc078f922008-11-21 22:27:24 +00002382- Issue #4367: Python would segfault during compiling when the unicodedata
2383 module couldn't be imported and \N escapes were present.
2384
Georg Brandlba83f822010-03-14 09:50:54 +00002385- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2386 file objects with closefd=False. The file descriptor is still kept open but
2387 the file object behaves like a closed file. The ``FileIO`` object also got a
2388 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002389
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002390- Issue #4348: Some bytearray methods returned that didn't cause any change to
2391 the bytearray, returned the same bytearray instead of a copy.
2392
Georg Brandlba83f822010-03-14 09:50:54 +00002393- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00002394
Benjamin Peterson273c2332008-11-17 22:39:09 +00002395- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2396
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002397- Issue #4048: The parser module now correctly validates relative imports.
2398
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002399- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2400 exec statement.
2401
Georg Brandlba83f822010-03-14 09:50:54 +00002402- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2403 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002404
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002405- Issue #4209: Enabling unicode_literals and the print_function in the same
2406 __future__ import didn't work.
2407
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002408- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002409 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002410
Georg Brandlba83f822010-03-14 09:50:54 +00002411- On windows, ``os.chdir()`` given unicode was not working if
2412 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2413 this code path is really executed because I cannot move to such directory on
2414 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002415
Georg Brandlba83f822010-03-14 09:50:54 +00002416- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2417 element is temporarily replaced with an equivalent frozenset. But the
2418 eventual KeyError would always report the empty ``frozenset()`` as the missing
2419 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002420
Georg Brandlba83f822010-03-14 09:50:54 +00002421- Issue #4509: Various issues surrounding resize of bytearray objects to which
2422 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002423
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002424- Issue #4748: Lambda generators no longer return a value.

2427
Gregory P. Smithae91d092009-03-02 05:13:57 +00002428- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2429
Georg Brandlba83f822010-03-14 09:50:54 +00002430- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002432
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002433- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2434 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002435
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002436- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2437 returned them on 64bit platforms.
2438
Walter Dörwalded960ac2009-05-03 22:36:33 +00002439- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2440 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2441 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2442 of using the replace error handler in PyUnicode_DecodeUTF8().
2443
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002444- Issue #3739: The unicode-internal encoder now reports the number of characters
2445 consumed like any other encoder (instead of the number of bytes).
2446
Georg Brandlba83f822010-03-14 09:50:54 +00002447- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2448 allocator will be automatically disabled when running under Valgrind. This
2449 gives improved memory leak detection when running under Valgrind, while taking
2450 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003692- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3693 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003694 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3695 the tests if DISPLAY is defined but can't be used.

3699
Georg Brandlba83f822010-03-14 09:50:54 +00003700- Issue #5354: New test support function import_fresh_module() makes it easy to
3701 import both normal and optimised versions of modules. test_heapq and
3702 test_warnings have been adjusted to use it, tests for other modules with both
3703 C and Python implementations in the stdlib can be adjusted to use it over
3704 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003712- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3713 should cause a test to be skipped are now done using import_module from test
3714 support, which does the conversion.

3816
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003817- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3818 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3819 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3820 ``printf`` function, whereas PyString_FromFormat has an independent
3821 implementation and uses "%zd" on all platforms for size_t values.
3822 This makes a difference on win64, where ``printf`` needs "%Id" to display
3823 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003825- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3829 object; previously an int would be returned for small values. the __long__
3830 method is allowed to return either an int or a long, but the behaviour of
3831 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003833- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003839 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003840 was correctly parsed but parsing of subsequent arguments failed.
3841
Vinay Sajip35e3b032008-09-01 14:33:59 +00003842- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003843 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3844 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3845 when given a tuple of classes as second argument, were looking up
3846 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3847 type object.
3848
Neal Norwitz18aa3882008-08-24 05:04:52 +00003849- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00003975- Issue #3833: Use a different upgrade code for Win64 installers.
3976
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00003977- Issue #2271: Set SecureCustomProperties so that installation will properly
3978 use the TARGETDIR even for unprivileged users.
3979
Martin v. Löwis67543a92008-09-08 12:02:45 +00003980- Allow passing the MSI file name to merge.py.
3981
Vinay Sajip844f7412008-09-09 13:42:08 +00003982- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003983 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003986What's New in Python 2.6 beta 3?
3987================================
3988
Barry Warsaw07a4a382008-08-21 01:15:08 +00003989*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003990
3991Core and Builtins
3992-----------------
3993
Guido van Rossumf8402962008-08-20 15:01:50 +00003994- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3995 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3996 extensions do not automatically benefit from the class attribute
3997 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3998 to their tp_flags field if they care. This is a backwards
3999 compatibility feature; in 3.0, all types will use the cache by
4000 default.
4001
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004002- Keyword arguments can now follow starred arguments. (``f(a, *args,
4003 keyword=23)`` is now valid syntax.)
4004
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004005- ctypes function pointers that are COM methods have a boolean True
4006 value again.
4007
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004008- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4009 by denying s# to parse objects that have a releasebuffer procedure,
4010 and introducing s*.
4011
Georg Brandl1e13ea92008-08-11 09:07:59 +00004012- Issue #3537: Fix an assertion failure when an empty but presized dict
4013 object was stored in the freelist.
4014
Mark Dickinsonb6467572008-08-04 21:30:09 +00004015- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4016 ValueError consistently across platforms.
4017
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004018- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4019 (64bit Unix, for example), unichr() would truncate its argument and return
4020 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4021
Neal Norwitze7d8be82008-07-31 17:17:14 +00004022- Apply security patches from Apple.
4023
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004024- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4025 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4026
Antoine Pitrou92f82162008-07-25 22:22:08 +00004027- Issue #1819: function calls with several named parameters are now on
4028 average 35% faster (as measured by pybench).
4029
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004030- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4031 the python debugger steps into a class statement: the free variables (local
4032 variables defined in an outer scope) would be deleted from the outer scope.
4033
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004034- Issue #2620: Overflow checking when allocating or reallocating memory
4035 was not always being done properly in some python types and extension
4036 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4037 all been updated to perform better checks and places in the code that
4038 would previously leak memory on the error path when such an allocation
4039 failed have been fixed.

4042-------
4043
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004044- Issue #3612: Added some missing basic types in ctypes.wintypes.
4045
Benjamin Petersone977ad42008-08-20 01:42:01 +00004046- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4047 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4048
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004049- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4050 version reported by these tools does not necessarily follow the python
4051 version numbering scheme, so the module is less strict when parsing it.
4052
Nick Coghlanf70385a2008-08-18 12:42:46 +00004053- Issue #2235: Added Py3k warnings for types which will become unhashable
4054 under the stricter __hash__ inheritance rules in 3.0. Several types
4055 which did not meet the rules for hash invariants and were already
4056 unhashable in 3.0 have now been explicitly flagged as unhashable in
4057 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4058 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4059
Brett Cannon88f801d2008-08-18 00:46:22 +00004060- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4061 imported into the module but exposed as part of the module's API.
4062
Brett Cannon7b96f072008-08-18 00:41:11 +00004063- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4064
Brett Cannon46225e72008-08-18 00:36:52 +00004065- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4066
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004067- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4068
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004069- Issue #3575: Incremental decoder's decode function now takes bytearray
4070 by using 's*' instead of 't#'.
4071
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004072- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004073 fails unicode conversion on 2nd parameter. (windows only)
4074
Georg Brandl222e2082010-08-01 22:27:39 +00004075- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004076 in a redirect.
4077
Brett Cannonabe423e2008-08-16 21:47:07 +00004078- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004079 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004080
Facundo Batistaeb90b782008-08-16 14:44:07 +00004081- Issue #2776: fixed small issue when handling an URL with double slash
4082 after a 302 response in the case of not going through a proxy.
4083
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004084- Issue #2676: in the email package, content-type parsing was hanging on
4085 pathological input because of quadratic or exponential behaviour of a
4086 regular expression.
4087
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004088- Issue #3476: binary buffered reading through the new "io" library is now
4089 thread-safe.
4090
Brett Cannonbf3157b2008-08-14 05:00:03 +00004091- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4092 since mimetools itself is deprecated. Because modules are cached, all
4093 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4094
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004095- Issue #3134: shutil referenced undefined WindowsError symbol.
4096
Robert Schuppenies14646332008-08-10 11:01:53 +00004097- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4098 menu entries were not deleted.
4099
Brett Cannon83e81842008-08-09 23:30:55 +00004100- Copied the implementation of reduce() to _functools.reduce() to have a
4101 version that did not raise a DeprecationWarning under -3.
4102
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004103- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4104 a MemoryError rather than silently stop the iteration.
4105
Guido van Rossum59ce9012008-08-09 14:55:34 +00004106- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4107 to _sre.compile() will now be rejected. This should not affect anybody
4108 since the re.compile() function never generates invalid re-bytecode.
4109
Skip Montanaroa032bf42008-08-08 22:52:51 +00004110- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4111 upon first access it can be automatically initialized from the csv file if
4112 it wasn't initialized during instantiation.
4113
Brett Cannon3aa2a492008-08-06 22:28:09 +00004114- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4115 the reload() built-in has been removed.
4116
Brett Cannon7e30b672008-08-04 21:52:25 +00004117- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004118 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004119 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4120 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4121 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4122 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4123 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004124
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004125- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4126 raised an AttributeError.
4127
Benjamin Peterson01a24322008-07-28 23:35:27 +00004128- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004129 asking for a specific length. This problem only affected files opened
4130 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004131
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004132- Issue #3449: Update decimal module to use most recent specification
4133 (v. 1.68) and tests (v. 2.58) from IBM.
4134
Georg Brandl222e2082010-08-01 22:27:39 +00004135- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004136

4139
Georg Brandlf9efabb2008-07-23 15:16:45 +00004140- Deprecate the "ast" parser function aliases.
4141
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004142- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4143
4144- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4145 invalid arguments.
4146
4147- Issue #3302: Fix several crashes when calling locale's gettext functions
4148 with None arguments.
4149
4150- Issue #3389: Allow resolving dotted names for handlers in logging
4151 configuration files.
4152
4153- Deprecate the sunaudio module for removal in Python 3.0.
4154
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004155- Issue #3394: zipfile.writestr sets external attributes when passed a
4156 file name rather than a ZipInfo instance, so files are extracted with
4157 mode 0600 rather than 000 under Unix.
4158
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004159- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4160 argument in python 2.5, this broke code that subclassed Popen to include its
4161 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4170
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004171- Issue #2235: the C API function PyObject_HashNotImplemented and its
4172 interaction with the tp_hash slot (added in 2.6b2) are now documented
4173
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004174- Issue #643841: The language reference now provides more detailed
4175 coverage of the lookup process for special methods. The disclaimers
4176 regarding lack of coverage of new-style classes have also been
4177 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004180What's New in Python 2.6 beta 2?
4181================================
4182
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004183*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004185Core and Builtins
4186-----------------
4187
Georg Brandl3e483f62008-07-16 22:57:41 +00004188- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4189 its methods now allow for items objects that can be converted to
4190 an integer using operator.index().
4191
Mark Dickinson64b7e502008-07-16 09:40:03 +00004192- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4193 produced a ValueError instead of giving the correct float.
4194
Eric Smitha5fa5a22008-07-16 00:11:49 +00004195- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4196 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4197
Mark Dickinson7103aa42008-07-15 19:08:33 +00004198- Issue #3008: the float type has a new instance method 'float.hex'
4199 and a new class method 'float.fromhex' to convert floating-point
4200 numbers to and from hexadecimal strings, respectively.
4201
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004202- Issue #2235: __hash__ is once again inherited by default. To allow
4203 collections.Hashable to remain meaningful in the presence of the
4204 default hash implementation (object.__hash__), it is now possible
4205 to explicit block inheritance of hash by setting __hash__=None at
4206 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4207 level.
4208
Nick Coghlanb028f502008-07-13 14:52:36 +00004209- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4210 the parent module cannot be found while performing an absolute import.
4211 This means that an incorrectly defined __package__ attribute will
4212 now only prevent relative imports in that module rather than causing
4213 all imports from that module to fail.
4214
Nick Coghlan14ff9942008-07-08 14:21:42 +00004215- Issue #2517: Allow unicode messages in Exceptions again by correctly
4216 bypassing the instance dictionary when looking up __unicode__ on
4217 new-style classes.
4218
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004219- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4220 set to a custom object whose write() method happens to install
4221 another file in sys.stdout.
4222
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004223- Issue #3088: Corrected a race condition in classes derived from
4224 threading.local: the first member set by a thread could be saved in
4225 another thread's dictionary.
4226
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004227- Issue #3004: Minor change to slice.indices(): the start and stop
4228 arguments are now treated identically, making the behaviour easier
4229 to describe and understand. For example, slice(None, -10,
4230 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4231 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4232 10, -1).
4233
Georg Brandl278fc502008-07-19 12:46:12 +00004234- Issue #3219: Calling a function with repeated keyword arguments,
4235 f(a=2, a=23), would not cause a syntax error. This was a regression
4236 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004237
Georg Brandl278fc502008-07-19 12:46:12 +00004238- Issue #2862: Make int and float freelist management consistent with
4239 other freelists. Changes their CompactFreeList apis into
4240 ClearFreeList apis and calls them via gc.collect().

4246 api functions without holding the GIL, which could lead to a fatal
4247 error when they failed.
4248
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004249- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004686 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004687
4688 This is controlled by the configure argument ``--with-universal-archs``:
4689
4690 - ``--with-universal-archs=all``: install 4-way universal
4691
4692 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4693
4694 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4695
4696 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004748- Issue #1631171: Re-implement the 'warnings' module in C (the
4749 original Python code has been kept as backup). This will allow for
4750 using the 'warning's machinery in such places as the parser where
4751 use of pure Python code is not possible. Both the ``showarning()``
4752 and ``formatwarning()`` gain an optional 'line' argument which is
4753 not called by default for backwards-compatibility reasons. Setting
4754 ``warnings.showwarning()`` to an implementation that lacks support
4755 for the ``line`` argument will raise a DeprecationWarning.

4779
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004780- The getpass module has been improved on Unix. It now uses /dev/tty
4781 by default and uses stderr instead of stdout. A GetPassWarning is
4782 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004818- Issue #2550: The approach used by client/server code for obtaining
4819 ports to listen on in network-oriented tests has been refined in an
4820 effort to facilitate running multiple instances of the entire
4821 regression test suite in parallel without issue.
4822 test_support.bind_port() has been fixed such that it will always
4823 return a unique port -- which wasn't always the case with the
4824 previous implementation, especially if socket options had been set
4825 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4826 new implementation of bind_port() will actually raise an exception
4827 if it is passed an AF_INET/SOCK_STREAM socket with either the
4828 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4829 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4830 the socket it's been passed. This currently only applies to
4831 Windows. This option prevents any other sockets from binding to the
4832 host/port we've bound to, thus removing the possibility of the
4833 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4834 when a second SOCK_STREAM socket binds and accepts to a host/port
4835 that's already been bound by another socket. The optional preferred
4836 port parameter to bind_port() has been removed. Under no
4837 circumstances should tests be hard coding ports!
4838
4839 test_support.find_unused_port() has also been introduced, which will
4840 pass a temporary socket object to bind_port() in order to obtain an
4841 unused port. The temporary socket object is then closed and
4842 deleted, and the port is returned. This method should only be used
4843 for obtaining an unused port in order to pass to an external program
4844 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4845 a parameter to a server-oriented class that doesn't give you direct
4846 access to the underlying socket used.
4847
4848 Finally, test_support.HOST has been introduced, which should be used
4849 for the host argument of any relevant socket calls (i.e. bind and
4850 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004851
4852 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004854 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4855 test_asynchat and test_socket_ssl.
4856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857 It is now possible for multiple instances of the regression test
4858 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00005127- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005128 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005137- Added the future_builtins module, which contains hex() and oct().
5138 These are the PEP 3127 version of these functions, designed to be
5139 compatible with the hex() and oct() builtins from Python 3.0. They
5140 differ slightly in their output formats from the existing, unchanged
5141 Python 2.6 builtins. The expected usage of the future_builtins
5142 module is:
5143 from future_builtins import hex, oct
5144
Eric Smith7ef40bf2008-02-20 23:34:22 +00005145- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5146 exponents for exponents with absolute value < 100. Follows C99
5147 standard. This is a change on Windows, which would use 3 digits.
5148 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5149 so that any alterations it does to the resulting string will be
5150 available in stringlib/formatter.h (for float.__format__).
5151
Eric Smith5a3c1352008-02-19 13:21:56 +00005152- Implemented PEP 3101, Advanced String Formatting. This adds a new
5153 builtin format(); a format() method for str and unicode; a
5154 __format__() method to object, str, unicode, int, long, float, and
5155 datetime; the class string.Formatter; and the C API
5156 PyObject_Format().
5157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Fixed several potential crashes, all caused by specially crafted
5159 __del__ methods exploiting objects in temporarily inconsistent
5160 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005161
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005162- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163 prevent a possible crash: an Abstract Base Class would try to access
5164 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005165

Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Clear all free lists during a gc.collect() of the highest generation
5170 in order to allow pymalloc to free more arenas. Python may give back
5171 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Issue #2045: Fix an infinite recursion triggered when printing a
5174 subclass of collections.defaultdict, if its default_factory is set
5175 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005176
Christian Heimesf75dbef2008-02-08 00:11:31 +00005177- Fixed a minor memory leak in dictobject.c. The content of the free
5178 list was not freed on interpreter shutdown.
5179
Georg Brandl21e99f42010-03-07 15:23:59 +00005180- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005181 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005182
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5184 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005185 to compact the internal free lists of pre-allocted ints and floats.
5186
Georg Brandl3ee81df2008-05-17 18:14:43 +00005187- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5188 calls. Python expected the return type int but the fork familie
5189 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005190
Georg Brandl3ee81df2008-05-17 18:14:43 +00005191- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5192 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005203- Patch #1473257: generator objects gain a gi_code attribute. This is
5204 the same object as the func_code attribute of the function that
5205 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005206
Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Issue #1920: "while 0" statements were completely removed by the
5208 compiler, even in the presence of an "else" clause, which is
5209 supposed to be run when the condition is false. Now the compiler
5210 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005211
Guido van Rossumeead05f2008-01-24 18:21:02 +00005212- A few crashers fixed: weakref_in_del.py (issue #1377858);
5213 loosing_dict_ref.py (issue #1303614, test67.py);
5214 borrowed_ref_[34].py (not in tracker).
5215
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005216- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005217 suppressed while an extension is loaded by calling SetErrorMode in
5218 dynload_win.c. The error is still reported properly.
5219
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005221 several extension methods and modules do not work without unicode
5222 support.
5223
Georg Brandl26543b12008-01-21 18:36:51 +00005224- Issue #1882: when compiling code from a string, encoding cookies in the
5225 second line of code were not always recognized correctly.
5226
Georg Brandl14404b62008-01-19 19:27:05 +00005227- Issue #1679: "0x" was taken as a valid integer literal.
5228
Georg Brandl6caad7d2008-01-26 14:19:22 +00005229- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005230 added.
5231
Christian Heimesc94e2b52008-01-14 04:13:37 +00005232- sys.float_info / PyFloat_GetInfo: The floating point information
5233 object was converted from a dict to a specialized structseq object.
5234
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235- Patch #1816: Added sys.flags structseq. It exposes the status of
5236 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005237
Georg Brandl3ee81df2008-05-17 18:14:43 +00005238- Objects/structseq.c: Implemented new structseq representation. The
5239 patch makes structseqs (e.g. the return value of os.stat) more
5240 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005241
Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Patch #1700288: added a type attribute cache that caches method
5243 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005244

5251 envvar and sys.dont_write_bytecode attribute. All these can be set
5252 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Improve some exception messages when Windows fails to load an
5255 extension module. Now we get for example '%1 is not a valid Win32
5256 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005264 and INF. float("nan"), float("inf") and float("-inf") now work on
5265 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005266
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267- Compiler now generates simpler and faster code for dictionary
5268 literals. The oparg for BUILD_MAP now indicates an estimated
5269 dictionary size. There is a new opcode, STORE_MAP, for adding
5270 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005318- Issue #1686386: Tuple's tp_repr did not take into account the
5319 possibility of having a self-referential tuple, which is possible
5320 from C code. Nor did object's tp_str consider that a type's tp_str
5321 could do something that could lead to an inifinite recursion.
5322 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5323 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005325- Issue #1164: It was possible to trigger deadlock when using the
5326 'print' statement to write to a file since the GIL was not released
5327 as needed. Now PyObject_Print() does the right thing along with
5328 various tp_print implementations of the built-in types and those in
5329 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005330
Georg Brandl3ee81df2008-05-17 18:14:43 +00005331- Issue #1147: Exceptions were directly allowing string exceptions in
5332 their throw() method even though string exceptions no longer
5333 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00005338- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005339 PyObject_Call() never calling back out to Python code to trigger
5340 recursion depth updates/checks. Required the creation of a static
5341 RuntimeError instance in case normalizing an exception put the
5342 recursion check value past its limit. Fixes crashers
5343 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005358- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005359 __*__ attributes. (Some already existed, e.g., __doc__ and
5360 __name__.)

5366 calls.
5367
Collin Winter62903052007-05-18 23:11:24 +00005368- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005369 "except E as target:". This is to provide forwards compatibility
5370 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005377- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005378 setting a plain string, ie don't expand to single letter identifiers.
5379
Raymond Hettinger13936692007-04-11 18:40:58 +00005380- Request #1191699: Slices can now be pickled.
5381
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005382- Request #1193128: str.translate() now allows a None argument for

5384 remaining characters.
5385
Georg Brandl5cb76c12007-03-21 09:00:39 +00005386- Patch #1682205: a TypeError while unpacking an iterable is no longer

5390
Guido van Rossum143b5642007-03-23 04:58:42 +00005391- Bug #1683368: The object.__init__() and object.__new__() methods are
5392 now stricter in rejecting excess arguments. The only time when
5393 either allows excess arguments is when it is not overridden and the
5394 other one is. For backwards compatibility, when both are
5395 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005396 warning later). Also, type.__init__() insists on the same signature
5397 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005399- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5400 object to complex using its __complex__() method before falling back
5401 to the __float__() method. Therefore, the functions in the cmath
5402 module now can operate on objects that define a __complex__()
5403 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005421- Bug #1678647: write a newline after printing an exception in any
5422 case, even when converting the value to a string failed.
5423
Georg Brandl871f1bc2007-03-12 13:17:36 +00005424- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425 its argument, if it exists. If not, it will work like before. This
5426 allows customizing the output of dir() in the presence of a
5427 __getattr__().

5437 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005438
Georg Brandlaa2321b2007-03-07 00:40:28 +00005439- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440 makes the filenames the warning module prints much more sensible
5441 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005454- Patch #1674228: when assigning a slice (old-style), check for the
5455 sq_ass_slice instead of the sq_slice slot.
5456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005560 generator expressions (x for x, in ... ) works again. Fixing this
5561 problem required changing the .pyc magic number. This means that
5562 .pyc files generated before 2.5c2 will be regenerated.

6088 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006369- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6370 with RFC 3207 and forgets any knowledge obtained from the server not
6371 obtained from the TLS negotiation itself. Patch contributed by Bill
6372 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006375 that the SMTP.starttls() caller no longer needs to call ehlo()
6376 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006377 does not claim to support starttls. Adds the
6378 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6379 Fenner.

6459 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6460 silently miscode subclasses of those types. Now, it raises a
6461 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006462

Georg Brandl3ee81df2008-05-17 18:14:43 +00006477 time so that opening a database previously created with the DB_DUP
6478 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6479 opens. Specifically: dictionary assignment to a DB object will
6480 replace all values for a given key when the database allows
6481 duplicate values. DB users should use DB.put(k, v) when they want
6482 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006483

6489 characters with ASCII value less than 32. Also, it correctly quotes
6490 dots only if they occur on a single line, as opposed to the previous
6491 behavior of quoting dots if they are the second character of any
6492 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006493

6815-----
6816
Georg Brandl3ee81df2008-05-17 18:14:43 +00006817- Unified naming convention for free lists and their limits. All free
6818 lists in Object/ are named ``free_list``, the counter ``numfree``
6819 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6820 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6823 to ``PyTuple_SetItem``, it can be used to populate a brand new
6824 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006825
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006826- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

6829 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6830 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006831
6832- Patch #1720595: add T_BOOL to the range of structmember types.
6833
6834- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6835 ``PyFloat_GetInfo()`` to the float API.
6836
Georg Brandl3ee81df2008-05-17 18:14:43 +00006837- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6838 of w# format code incorrectly truncated the length to an int, even
6839 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6840 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6843 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006844
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- PEP 3123: Provide forward compatibility with Python 3.0, while
6846 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6847 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6850 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006851
6852- Patch #1733960: Allow T_LONGLONG to accept ints.
6853

6859
6860- Fix some leftovers from the conversion from int to Py_ssize_t
6861 (relevant to strings and sequences of more than 2**31 items).
6862
6863- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6864 outside of pystate.c and should not be necessary.
6865
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6867 absolute imports. In earlier versions they might have used relative
6868 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006869
Georg Brandl3ee81df2008-05-17 18:14:43 +00006870- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6871 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006872
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6874 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006880- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6881 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6882 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6883 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006884

Georg Brandl3ee81df2008-05-17 18:14:43 +00006898- Removed the macfs module. It had been deprecated since Python 2.5.
6899 This lead to the deprecation of macostools.touched() as it relied
6900 solely on macfs and was a no-op under OS X.
