Eric Smitha985a3a2009-05-05 18:26:08 +0000159- Issue #5920: For float.__format__, change the behavior with the
160 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
161 to be like 'g' but with at least one decimal point and with a
162 default precision of 12. Previously, the behavior the same but with
163 a default precision of 6. This more closely matches str(), and
164 reduces surprises when adding alignment flags to the empty
165 presentation type. This also affects the new complex.__format__ in
166 the same way.
167

197
198- Issue #5515: 'n' formatting for ints, longs, and floats handles
199 leading zero formatting poorly.

232 reduce the size of collections and therefore the garbage collection overhead
233 on long-running programs, depending on their particular use of datatypes.
234
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000235- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

303 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000304 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000305 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

308
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000309- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
310 an existing .py counterpart, override the co_filename attributes of all
311 code objects if the original filename is obsolete (which can happen if the
312 file has been renamed, moved, or if it is accessed through different paths).
313 Patch by Ziga Seilnacht and Jean-Paul Calderone.
314
Martin v. Löwis5344c992009-01-02 20:32:55 +0000315- Issue #4075: Use OutputDebugStringW in Py_FatalError.
316
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000317- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
318 file with `str' filename on Windows.
319
Antoine Pitrouaa687902009-01-01 14:11:22 +0000320- Issue #3680: Reference cycles created through a dict, set or deque iterator
321 did not get collected.
322
Nick Coghlan180e4002008-12-30 01:18:48 +0000323- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
324 where the tp_hash and tp_dict slots are both NULL.
325
Benjamin Peterson7af65562008-12-29 17:56:58 +0000326- Issue #4764: With io.open, IOError.filename is set when trying to open a
327 directory on POSIX systems.
328
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000329- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
330 systems.
331
Georg Brandl6425a2f2008-12-28 11:54:53 +0000332- Issue #4759: None is now allowed as the first argument of
333 bytearray.translate(). It was always allowed for bytes.translate().
334
Skip Montanarof205c132008-12-23 03:30:15 +0000335- Added test case to ensure attempts to read from a file opened for writing
336 fail.
337
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000338- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
339 print elapsed times, not only when some objects are uncollectable /
340 unreachable. Original patch by Neil Schemenauer.
341

348 context manager returns a value that cannot be converted to a bool.
349
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000350- Issue #4597: Fixed several opcodes that weren't always propagating
351 exceptions.
352
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000353- Issue #4445: Replace "sizeof(PyStringObject)" with
354 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
355 str instances. On a typical machine this saves 3 bytes of memory
356 (on average) per string allocation.
357
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000358- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
359 interpreter to abort ("Fatal Python error: Could not reset the stack!")
360 instead of throwing a MemoryError.
361
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000362- Issue #3689: The list reversed iterator now supports __length_hint__
363 instead of __len__. Behavior now matches other reversed iterators.
364
Benjamin Petersonc078f922008-11-21 22:27:24 +0000365- Issue #4367: Python would segfault during compiling when the unicodedata
366 module couldn't be imported and \N escapes were present.
367
Vinay Sajip213faca2008-12-03 23:22:58 +0000368- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000369 method on file objects with closefd=False. The file descriptor is still
370 kept open but the file object behaves like a closed file. The ``FileIO``
371 object also got a new readonly attribute ``closefd``.
372
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000373- Issue #4348: Some bytearray methods returned that didn't cause any change to
374 the bytearray, returned the same bytearray instead of a copy.
375
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000376- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
377
Benjamin Peterson273c2332008-11-17 22:39:09 +0000378- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
379
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000380- Issue #4048: The parser module now correctly validates relative imports.
381
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000382- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
383 exec statement.
384
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000385- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
386 method does not return iterators for the 4th and 5th items.
387
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000388- Issue #4209: Enabling unicode_literals and the print_function in the same
389 __future__ import didn't work.
390
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000391- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000392 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000393
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000394- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
395 returned a path longer than MAX_PATH. (But It's doubtful this code path is
396 really executed because I cannot move to such directory on win2k)
397
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000398- Issue #4069: When set.remove(element) is used with a set element, the element
399 is temporarily replaced with an equivalent frozenset. But the eventual
400 KeyError would always report the empty frozenset([]) as the missing key. Now
401 it correctly refers to the initial element.
402
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000403- Issue #4509: Various issues surrounding resize of bytearray objects to
404 which there are buffer exports.
405
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000406- Issue #4748: Lambda generators no longer return a value.

413 short file names.
414
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000415- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
416 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000417
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000418- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
419 returned them on 64bit platforms.
420
Walter Dörwalded960ac2009-05-03 22:36:33 +0000421- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
422 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
423 step. This avoids problems with counting UTF-8 bytes that ignores the effect
424 of using the replace error handler in PyUnicode_DecodeUTF8().
425
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000426- Issue #3739: The unicode-internal encoder now reports the number of characters
427 consumed like any other encoder (instead of the number of bytes).

437
Nick Coghlan49868cb2009-11-15 07:30:34 +0000438- Issue #6816: runpy now provides a run_path function that allows Python code
439 to execute file paths that refer to source or compiled Python files as well
440 as zipfiles, directories and other valid sys.path entries that contain a
441 __main__.py file. This allows applications that run other Python scripts to
442 support the same flexibility as the CPython command line itself.
443
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000444- Issue #7318: multiprocessing now uses a timeout when it fails to establish
445 a connection with another process, rather than looping endlessly. The
446 default timeout is 20 seconds, which should be amply sufficient for
447 local connections.
448
Antoine Pitrou0734c632009-11-10 20:49:30 +0000449- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

465 failures on systems with slightly bogus mtime behaviour.
466
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000467- Issue #7246 & Issue #7208: getpass now properly flushes input before
468 reading from stdin so that existing input does not confuse it and
469 lead to incorrect entry or an IOError. It also properly flushes it
470 afterwards to avoid the terminal echoing the input afterwards on
471 OSes such as Solaris.
472
Mark Dickinson6f390012009-10-29 12:11:18 +0000473- Issue #7233: Fix a number of two-argument Decimal methods to make

475 fix buggy handling of large arguments (those with coefficient longer
476 than the current precision) in shift and rotate.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001721 AttributeError instead of RuntimeError, depending in which C API call
1722 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001740- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1741
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001742- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1743 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1744 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1745 ``printf`` function, whereas PyString_FromFormat has an independent
1746 implementation and uses "%zd" on all platforms for size_t values.
1747 This makes a difference on win64, where ``printf`` needs "%Id" to display
1748 64bit values.
1749
Benjamin Peterson97179b02008-09-09 20:55:01 +00001750- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1751 error.
1752
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001753- Issue #3777: long() applied to a float object now always return a long
1754 object; previously an int would be returned for small values. the __long__
1755 method is allowed to return either an int or a long, but the behaviour of
1756 float objects should not change to respect backward compatibility.
1757
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001758- Issue #3751: str.rpartition would perform a left-partition when called with
1759 a unicode argument.
1760
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001761- Issue #3683: Fix compilation when --without-threads is given.
1762
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001763- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001764 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001765 was correctly parsed but parsing of subsequent arguments failed.
1766
Vinay Sajip35e3b032008-09-01 14:33:59 +00001767- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001768 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1769 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1770 when given a tuple of classes as second argument, were looking up
1771 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1772 type object.
1773
Neal Norwitz18aa3882008-08-24 05:04:52 +00001774- Fix crashes on memory allocation failure found with failmalloc.
1775
1776- Fix memory leaks found with valgrind and update suppressions file.
1777
1778- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1779
1780- Fix problem using wrong name in decimal module reported by pychecker.
1781
Christian Heimes7d4c3172008-08-22 19:47:25 +00001782- Silenced another compiler warning about a used but not defined
1783 function 'stringlib_contains_obj'.

Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001788- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1789 library targets in the Makefile.
1790
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001791- Issue #1204: The configure script now tests for additional libraries
1792 that may be required when linking against readline. This fixes issues
1793 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1815
Nick Coghland2e09382008-09-11 12:11:06 +00001816- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001817 return a list or None rather than a custom object.
1818
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001819- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1843 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1844 for catch_warnings() also led to an improvement in the raising of a
1845 DeprecationWarning related to warnings.warn_explicit().
1846
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001847- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001911What's New in Python 2.6 beta 3?
1912================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001915
1916Core and Builtins
1917-----------------
1918
Guido van Rossumf8402962008-08-20 15:01:50 +00001919- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1920 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1921 extensions do not automatically benefit from the class attribute
1922 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1923 to their tp_flags field if they care. This is a backwards
1924 compatibility feature; in 3.0, all types will use the cache by
1925 default.
1926
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001927- Keyword arguments can now follow starred arguments. (``f(a, *args,
1928 keyword=23)`` is now valid syntax.)
1929
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001930- ctypes function pointers that are COM methods have a boolean True
1931 value again.
1932
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001933- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1934 by denying s# to parse objects that have a releasebuffer procedure,
1935 and introducing s*.
1936
Georg Brandl1e13ea92008-08-11 09:07:59 +00001937- Issue #3537: Fix an assertion failure when an empty but presized dict
1938 object was stored in the freelist.
1939
Mark Dickinsonb6467572008-08-04 21:30:09 +00001940- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1941 ValueError consistently across platforms.
1942
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001943- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1944 (64bit Unix, for example), unichr() would truncate its argument and return
1945 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1946
Neal Norwitze7d8be82008-07-31 17:17:14 +00001947- Apply security patches from Apple.
1948
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001949- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1950 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1951
Antoine Pitrou92f82162008-07-25 22:22:08 +00001952- Issue #1819: function calls with several named parameters are now on
1953 average 35% faster (as measured by pybench).
1954
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001955- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1956 the python debugger steps into a class statement: the free variables (local
1957 variables defined in an outer scope) would be deleted from the outer scope.
1958
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001959- Issue #2620: Overflow checking when allocating or reallocating memory
1960 was not always being done properly in some python types and extension
1961 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1962 all been updated to perform better checks and places in the code that
1963 would previously leak memory on the error path when such an allocation
1964 failed have been fixed.

1968
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001969- Issue #3612: Added some missing basic types in ctypes.wintypes.
1970
Benjamin Petersone977ad42008-08-20 01:42:01 +00001971- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1972 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1973
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001974- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1975 version reported by these tools does not necessarily follow the python
1976 version numbering scheme, so the module is less strict when parsing it.
1977
Nick Coghlanf70385a2008-08-18 12:42:46 +00001978- Issue #2235: Added Py3k warnings for types which will become unhashable
1979 under the stricter __hash__ inheritance rules in 3.0. Several types
1980 which did not meet the rules for hash invariants and were already
1981 unhashable in 3.0 have now been explicitly flagged as unhashable in
1982 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1983 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1984
Brett Cannon88f801d2008-08-18 00:46:22 +00001985- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1986 imported into the module but exposed as part of the module's API.
1987
Brett Cannon7b96f072008-08-18 00:41:11 +00001988- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1989

2098
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002099- Issue #643841: The language reference now provides more detailed

2111-----------------
2112
Georg Brandl3e483f62008-07-16 22:57:41 +00002113- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2114 its methods now allow for items objects that can be converted to
2115 an integer using operator.index().
2116
Mark Dickinson64b7e502008-07-16 09:40:03 +00002117- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2118 produced a ValueError instead of giving the correct float.
2119
Eric Smitha5fa5a22008-07-16 00:11:49 +00002120- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2121 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2122
Mark Dickinson7103aa42008-07-15 19:08:33 +00002123- Issue #3008: the float type has a new instance method 'float.hex'
2124 and a new class method 'float.fromhex' to convert floating-point
2125 numbers to and from hexadecimal strings, respectively.
2126
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002127- Issue #2235: __hash__ is once again inherited by default. To allow
2128 collections.Hashable to remain meaningful in the presence of the
2129 default hash implementation (object.__hash__), it is now possible
2130 to explicit block inheritance of hash by setting __hash__=None at
2131 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2132 level.
2133
Nick Coghlanb028f502008-07-13 14:52:36 +00002134- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2135 the parent module cannot be found while performing an absolute import.
2136 This means that an incorrectly defined __package__ attribute will
2137 now only prevent relative imports in that module rather than causing
2138 all imports from that module to fail.
2139
Nick Coghlan14ff9942008-07-08 14:21:42 +00002140- Issue #2517: Allow unicode messages in Exceptions again by correctly

2150 another thread's dictionary.
2151
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002152- Issue #3004: Minor change to slice.indices(): the start and stop
2153 arguments are now treated identically, making the behaviour easier
2154 to describe and understand. For example, slice(None, -10,
2155 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2156 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2157 10, -1).
2158
Georg Brandl278fc502008-07-19 12:46:12 +00002159- Issue #3219: Calling a function with repeated keyword arguments,
2160 f(a=2, a=23), would not cause a syntax error. This was a regression
2161 from 2.4 caused by the switch to the new compiler.

2200 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002201 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002202 content-length. The problem had been corrected in the 2.4 branch, but never

2561 large to fit in a C long. ldexp(x, n) now returns a zero (with
2562 suitable sign) if n is large and negative; previously, it raised

2608
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002609- On MacOS X it is now possible to install the framework in 64-bit
2610 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002611 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002612
2613 This is controlled by the configure argument ``--with-universal-archs``:
2614
2615 - ``--with-universal-archs=all``: install 4-way universal
2616
2617 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2618
2619 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2620
2621 This option should be used in combination with ``--enable-universalsdk=``.
2622
2623 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 +00002673- Issue #1631171: Re-implement the 'warnings' module in C (the
2674 original Python code has been kept as backup). This will allow for
2675 using the 'warning's machinery in such places as the parser where
2676 use of pure Python code is not possible. Both the ``showarning()``
2677 and ``formatwarning()`` gain an optional 'line' argument which is
2678 not called by default for backwards-compatibility reasons. Setting
2679 ``warnings.showwarning()`` to an implementation that lacks support
2680 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Issue #2550: The approach used by client/server code for obtaining
2744 ports to listen on in network-oriented tests has been refined in an
2745 effort to facilitate running multiple instances of the entire
2746 regression test suite in parallel without issue.
2747 test_support.bind_port() has been fixed such that it will always
2748 return a unique port -- which wasn't always the case with the
2749 previous implementation, especially if socket options had been set
2750 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2751 new implementation of bind_port() will actually raise an exception
2752 if it is passed an AF_INET/SOCK_STREAM socket with either the
2753 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2754 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2755 the socket it's been passed. This currently only applies to
2756 Windows. This option prevents any other sockets from binding to the
2757 host/port we've bound to, thus removing the possibility of the
2758 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2759 when a second SOCK_STREAM socket binds and accepts to a host/port
2760 that's already been bound by another socket. The optional preferred
2761 port parameter to bind_port() has been removed. Under no
2762 circumstances should tests be hard coding ports!
2763
2764 test_support.find_unused_port() has also been introduced, which will
2765 pass a temporary socket object to bind_port() in order to obtain an
2766 unused port. The temporary socket object is then closed and
2767 deleted, and the port is returned. This method should only be used
2768 for obtaining an unused port in order to pass to an external program
2769 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2770 a parameter to a server-oriented class that doesn't give you direct
2771 access to the underlying socket used.
2772
2773 Finally, test_support.HOST has been introduced, which should be used
2774 for the host argument of any relevant socket calls (i.e. bind and
2775 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002776
2777 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002779 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2780 test_asynchat and test_socket_ssl.
2781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782 It is now possible for multiple instances of the regression test
2783 suite to run in parallel without issue.

2836
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002837- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2839 Plane. This affected raw unicode literals and the
2840 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2841 this case, like normal unicode literals and the 'unicode-escape'
2842 codec.

3050-----------------
3051
Fred Drakea8ee94b2008-03-01 02:45:07 +00003052- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003053 644. The mode is now inherited from the py file.

3056
3057- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003058
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003059- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003060 issue 215555 for a discussion.
3061
Eric Smitha73fbe72008-02-23 03:09:44 +00003062- Added the future_builtins module, which contains hex() and oct().
3063 These are the PEP 3127 version of these functions, designed to be
3064 compatible with the hex() and oct() builtins from Python 3.0. They
3065 differ slightly in their output formats from the existing, unchanged
3066 Python 2.6 builtins. The expected usage of the future_builtins
3067 module is:
3068 from future_builtins import hex, oct
3069
Eric Smith7ef40bf2008-02-20 23:34:22 +00003070- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3071 exponents for exponents with absolute value < 100. Follows C99
3072 standard. This is a change on Windows, which would use 3 digits.
3073 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3074 so that any alterations it does to the resulting string will be
3075 available in stringlib/formatter.h (for float.__format__).
3076
Eric Smith5a3c1352008-02-19 13:21:56 +00003077- Implemented PEP 3101, Advanced String Formatting. This adds a new
3078 builtin format(); a format() method for str and unicode; a
3079 __format__() method to object, str, unicode, int, long, float, and
3080 datetime; the class string.Formatter; and the C API
3081 PyObject_Format().
3082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Fixed several potential crashes, all caused by specially crafted
3084 __del__ methods exploiting objects in temporarily inconsistent
3085 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003086
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003087- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088 prevent a possible crash: an Abstract Base Class would try to access
3089 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003090

Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Clear all free lists during a gc.collect() of the highest generation
3095 in order to allow pymalloc to free more arenas. Python may give back
3096 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Issue #2045: Fix an infinite recursion triggered when printing a
3099 subclass of collections.defaultdict, if its default_factory is set

Christian Heimesf75dbef2008-02-08 00:11:31 +00003102- Fixed a minor memory leak in dictobject.c. The content of the free
3103 list was not freed on interpreter shutdown.
3104
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- Limit free list of method and builtin function objects to 256
3106 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3109 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003110 to compact the internal free lists of pre-allocted ints and floats.
3111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3113 calls. Python expected the return type int but the fork familie
3114 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Patch #1473257: generator objects gain a gi_code attribute. This is
3129 the same object as the func_code attribute of the function that
3130 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1920: "while 0" statements were completely removed by the
3133 compiler, even in the presence of an "else" clause, which is
3134 supposed to be run when the condition is false. Now the compiler
3135 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003136
Guido van Rossumeead05f2008-01-24 18:21:02 +00003137- A few crashers fixed: weakref_in_del.py (issue #1377858);
3138 loosing_dict_ref.py (issue #1303614, test67.py);
3139 borrowed_ref_[34].py (not in tracker).
3140
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003141- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003142 suppressed while an extension is loaded by calling SetErrorMode in
3143 dynload_win.c. The error is still reported properly.
3144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003146 several extension methods and modules do not work without unicode
3147 support.
3148
Georg Brandl26543b12008-01-21 18:36:51 +00003149- Issue #1882: when compiling code from a string, encoding cookies in the
3150 second line of code were not always recognized correctly.
3151
Georg Brandl14404b62008-01-19 19:27:05 +00003152- Issue #1679: "0x" was taken as a valid integer literal.
3153
Georg Brandl6caad7d2008-01-26 14:19:22 +00003154- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003155 added.
3156
Christian Heimesc94e2b52008-01-14 04:13:37 +00003157- sys.float_info / PyFloat_GetInfo: The floating point information
3158 object was converted from a dict to a specialized structseq object.
3159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Patch #1816: Added sys.flags structseq. It exposes the status of
3161 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003162
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163- Objects/structseq.c: Implemented new structseq representation. The
3164 patch makes structseqs (e.g. the return value of os.stat) more
3165 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1700288: added a type attribute cache that caches method
3168 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003169
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003170- Bug #1776: __import__() no longer accepts filenames on any platform.
3171 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003172

3176 envvar and sys.dont_write_bytecode attribute. All these can be set
3177 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Improve some exception messages when Windows fails to load an
3180 extension module. Now we get for example '%1 is not a valid Win32
3181 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003182

Christian Heimes0a8143f2007-12-18 23:22:54 +00003188- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189 and INF. float("nan"), float("inf") and float("-inf") now work on
3190 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003191
Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Compiler now generates simpler and faster code for dictionary
3193 literals. The oparg for BUILD_MAP now indicates an estimated
3194 dictionary size. There is a new opcode, STORE_MAP, for adding
3195 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Patch #1739468: Directories and zipfiles containing a __main__.py
3225 file can now be directly executed by passing their name to the
3226 interpreter. The directory/zipfile is automatically inserted as the
3227 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Issue #1265: Fix a problem with sys.settrace, if the tracing
3230 function uses a generator expression when at the same time the
3231 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003232
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003233- sets and frozensets now have an isdisjoint() method.
3234

3236
Neal Norwitz44f326e2007-10-05 05:29:17 +00003237- Fix warnings found by the new version of the Coverity checker.
3238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- The enumerate() builtin function is no longer bounded to sequences
3240 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3241 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1686386: Tuple's tp_repr did not take into account the
3244 possibility of having a self-referential tuple, which is possible
3245 from C code. Nor did object's tp_str consider that a type's tp_str
3246 could do something that could lead to an inifinite recursion.
3247 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3248 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1164: It was possible to trigger deadlock when using the
3251 'print' statement to write to a file since the GIL was not released
3252 as needed. Now PyObject_Print() does the right thing along with
3253 various tp_print implementations of the built-in types and those in
3254 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Issue #1147: Exceptions were directly allowing string exceptions in
3257 their throw() method even though string exceptions no longer
3258 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003263- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264 PyObject_Call() never calling back out to Python code to trigger
3265 recursion depth updates/checks. Required the creation of a static
3266 RuntimeError instance in case normalizing an exception put the
3267 recursion check value past its limit. Fixes crashers
3268 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003269

Neal Norwitz0ac60192007-05-27 04:08:54 +00003283- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284 __*__ attributes. (Some already existed, e.g., __doc__ and
3285 __name__.)

3291 calls.
3292
Collin Winter62903052007-05-18 23:11:24 +00003293- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 "except E as target:". This is to provide forwards compatibility
3295 with Python 3.0.

3301
Vinay Sajip8549ce32007-05-06 17:53:37 +00003302- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003303 setting a plain string, ie don't expand to single letter identifiers.
3304
Raymond Hettinger13936692007-04-11 18:40:58 +00003305- Request #1191699: Slices can now be pickled.
3306
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003307- Request #1193128: str.translate() now allows a None argument for

3309 remaining characters.
3310
Georg Brandl5cb76c12007-03-21 09:00:39 +00003311- Patch #1682205: a TypeError while unpacking an iterable is no longer
3312 masked by a generic one with the message "unpack non-sequence".
3313
Neal Norwitzaa754b72007-03-21 06:39:48 +00003314- Remove unused file Python/fmod.c.
3315
Guido van Rossum143b5642007-03-23 04:58:42 +00003316- Bug #1683368: The object.__init__() and object.__new__() methods are
3317 now stricter in rejecting excess arguments. The only time when
3318 either allows excess arguments is when it is not overridden and the
3319 other one is. For backwards compatibility, when both are
3320 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003321 warning later). Also, type.__init__() insists on the same signature
3322 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3325 object to complex using its __complex__() method before falling back
3326 to the __float__() method. Therefore, the functions in the cmath
3327 module now can operate on objects that define a __complex__()
3328 method.

3338 ``object.__reduce_ex__()`` is called with an object that is faking
3339 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Patch #1680015: Don't modify __slots__ tuple if it contains an

3347 case, even when converting the value to a string failed.
3348
Georg Brandl871f1bc2007-03-12 13:17:36 +00003349- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350 its argument, if it exists. If not, it will work like before. This
3351 allows customizing the output of dir() in the presence of a
3352 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003353
Collin Winter276887b2007-03-12 16:11:39 +00003354- Patch #922167: Python no longer segfaults when faced with infinitely
3355 self-recursive reload() calls (as reported by bug #742342).

Georg Brandlaa2321b2007-03-07 00:40:28 +00003364- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365 makes the filenames the warning module prints much more sensible
3366 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003379- Patch #1674228: when assigning a slice (old-style), check for the
3380 sq_ass_slice instead of the sq_slice slot.
3381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- When printing an unraisable error, don't print exceptions. before
3383 the name. This duplicates the behavior whening normally printing
3384 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Bug #1377858: Fix the segfaulting of the interpreter when an object
3393 created a weakref on itself during a __del__ call for new-style
3394 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003434- Bug #1545497: when given an explicit base, int() did ignore NULs
3435 embedded in the string to convert.
3436
Georg Brandl846f73a2006-10-08 07:11:54 +00003437- Bug #1569998: break inside a try statement (outside a loop) is now
3438 recognized and rejected.
3439

3441
Armin Rigo7ccbca92006-10-04 12:17:45 +00003442- A number of places, including integer negation and absolute value,
3443 were fixed to not rely on undefined behaviour of the C compiler
3444 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00003445

Georg Brandl3ee81df2008-05-17 18:14:43 +00003450 keyword arguments any more (previously they accepted them, but
3451 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003485 generator expressions (x for x, in ... ) works again. Fixing this
3486 problem required changing the .pyc magic number. This means that
3487 .pyc files generated before 2.5c2 will be regenerated.

4296 obtained from the TLS negotiation itself. Patch contributed by Bill
4297 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004300 that the SMTP.starttls() caller no longer needs to call ehlo()
4301 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302 does not claim to support starttls. Adds the
4303 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4304 Fenner.

4384 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4385 silently miscode subclasses of those types. Now, it raises a
4386 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004387

Georg Brandl3ee81df2008-05-17 18:14:43 +00004402 time so that opening a database previously created with the DB_DUP
4403 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4404 opens. Specifically: dictionary assignment to a DB object will
4405 replace all values for a given key when the database allows
4406 duplicate values. DB users should use DB.put(k, v) when they want
4407 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004408

4414 characters with ASCII value less than 32. Also, it correctly quotes
4415 dots only if they occur on a single line, as opposed to the previous
4416 behavior of quoting dots if they are the second character of any
4417 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004418
