157 rejected; (2) parsing of strings representing infinities and nans
158 was locale aware; and (3) the interpretation of fromhex('-nan')
159 didn't match that of float('-nan').
160
Eric Smitha985a3a2009-05-05 18:26:08 +0000161- Issue #5920: For float.__format__, change the behavior with the
162 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
163 to be like 'g' but with at least one decimal point and with a
164 default precision of 12. Previously, the behavior the same but with
165 a default precision of 6. This more closely matches str(), and
166 reduces surprises when adding alignment flags to the empty
167 presentation type. This also affects the new complex.__format__ in
168 the same way.
169
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000170- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Eric Smithaca19e62009-04-22 13:29:05 +0000197- Implement PEP 378, Format Specifier for Thousands Separator, for
198 floats, ints, and longs.
199
200- Issue #5515: 'n' formatting for ints, longs, and floats handles
201 leading zero formatting poorly.
202

234 reduce the size of collections and therefore the garbage collection overhead
235 on long-running programs, depending on their particular use of datatypes.
236
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000237- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000303- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
304 collecting the oldest generation) so that allocating lots of objects without
305 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000306 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000307 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

310
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000311- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
312 an existing .py counterpart, override the co_filename attributes of all
313 code objects if the original filename is obsolete (which can happen if the
314 file has been renamed, moved, or if it is accessed through different paths).
315 Patch by Ziga Seilnacht and Jean-Paul Calderone.
316
Martin v. Löwis5344c992009-01-02 20:32:55 +0000317- Issue #4075: Use OutputDebugStringW in Py_FatalError.
318
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000319- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
320 file with `str' filename on Windows.
321
Antoine Pitrouaa687902009-01-01 14:11:22 +0000322- Issue #3680: Reference cycles created through a dict, set or deque iterator
323 did not get collected.
324
Nick Coghlan180e4002008-12-30 01:18:48 +0000325- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
326 where the tp_hash and tp_dict slots are both NULL.
327
Benjamin Peterson7af65562008-12-29 17:56:58 +0000328- Issue #4764: With io.open, IOError.filename is set when trying to open a
329 directory on POSIX systems.
330
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000331- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
332 systems.
333
Georg Brandl6425a2f2008-12-28 11:54:53 +0000334- Issue #4759: None is now allowed as the first argument of
335 bytearray.translate(). It was always allowed for bytes.translate().
336
Skip Montanarof205c132008-12-23 03:30:15 +0000337- Added test case to ensure attempts to read from a file opened for writing
338 fail.
339
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000340- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

348
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000349- Issue #4597: Fixed exception handling when the __exit__ function of a
350 context manager returns a value that cannot be converted to a bool.
351
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000352- Issue #4597: Fixed several opcodes that weren't always propagating
353 exceptions.
354
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000355- Issue #4445: Replace "sizeof(PyStringObject)" with
356 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
357 str instances. On a typical machine this saves 3 bytes of memory
358 (on average) per string allocation.
359
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000360- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
361 interpreter to abort ("Fatal Python error: Could not reset the stack!")
362 instead of throwing a MemoryError.
363
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000364- Issue #3689: The list reversed iterator now supports __length_hint__
365 instead of __len__. Behavior now matches other reversed iterators.
366
Benjamin Petersonc078f922008-11-21 22:27:24 +0000367- Issue #4367: Python would segfault during compiling when the unicodedata
368 module couldn't be imported and \N escapes were present.
369
Vinay Sajip213faca2008-12-03 23:22:58 +0000370- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000371 method on file objects with closefd=False. The file descriptor is still
372 kept open but the file object behaves like a closed file. The ``FileIO``
373 object also got a new readonly attribute ``closefd``.
374
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000375- Issue #4348: Some bytearray methods returned that didn't cause any change to
376 the bytearray, returned the same bytearray instead of a copy.
377
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000378- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
379
Benjamin Peterson273c2332008-11-17 22:39:09 +0000380- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
381
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000382- Issue #4048: The parser module now correctly validates relative imports.
383
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000384- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
385 exec statement.
386
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000387- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
388 method does not return iterators for the 4th and 5th items.
389
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000390- Issue #4209: Enabling unicode_literals and the print_function in the same
391 __future__ import didn't work.
392
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000393- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000394 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000395
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000396- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
397 returned a path longer than MAX_PATH. (But It's doubtful this code path is
398 really executed because I cannot move to such directory on win2k)
399
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000400- Issue #4069: When set.remove(element) is used with a set element, the element
401 is temporarily replaced with an equivalent frozenset. But the eventual
402 KeyError would always report the empty frozenset([]) as the missing key. Now
403 it correctly refers to the initial element.
404
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000405- Issue #4509: Various issues surrounding resize of bytearray objects to
406 which there are buffer exports.
407
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000408- Issue #4748: Lambda generators no longer return a value.

416
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000417- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
418 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000419
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000420- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
421 returned them on 64bit platforms.
422
Walter Dörwalded960ac2009-05-03 22:36:33 +0000423- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
424 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
425 step. This avoids problems with counting UTF-8 bytes that ignores the effect
426 of using the replace error handler in PyUnicode_DecodeUTF8().
427
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000428- Issue #3739: The unicode-internal encoder now reports the number of characters
429 consumed like any other encoder (instead of the number of bytes).

441
Nick Coghlan49868cb2009-11-15 07:30:34 +0000442- Issue #6816: runpy now provides a run_path function that allows Python code
443 to execute file paths that refer to source or compiled Python files as well
444 as zipfiles, directories and other valid sys.path entries that contain a
445 __main__.py file. This allows applications that run other Python scripts to
446 support the same flexibility as the CPython command line itself.
447
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000448- Issue #7318: multiprocessing now uses a timeout when it fails to establish
449 a connection with another process, rather than looping endlessly. The
450 default timeout is 20 seconds, which should be amply sufficient for
451 local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +0000467- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
468 a modification is done through it. This fixes inconsistencies and test
469 failures on systems with slightly bogus mtime behaviour.
470
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000471- Issue #7246 & Issue #7208: getpass now properly flushes input before
472 reading from stdin so that existing input does not confuse it and
473 lead to incorrect entry or an IOError. It also properly flushes it
474 afterwards to avoid the terminal echoing the input afterwards on
475 OSes such as Solaris.
476
Mark Dickinson6f390012009-10-29 12:11:18 +0000477- Issue #7233: Fix a number of two-argument Decimal methods to make

1555 TypeError used to be raised (with a confusing error message) for
1556 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

1601 leak-chasing test runs give sensible results. The previous method of
1602 reaping threads could return successfully while some Thread objects were
1603 still referenced. This also introduces a new private function:

1622 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1624 skip the tests if DISPLAY is defined but can't be used.

1630 it easy to import both normal and optimised versions of modules.
1631 test_heapq and test_warnings have been adjusted to use it, tests for
1632 other modules with both C and Python implementations in the stdlib
1633 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001642 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001643 from test support, which does the conversion.

1743
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001744- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1745
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001746- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1747 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1748 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1749 ``printf`` function, whereas PyString_FromFormat has an independent
1750 implementation and uses "%zd" on all platforms for size_t values.
1751 This makes a difference on win64, where ``printf`` needs "%Id" to display
1752 64bit values.
1753
Benjamin Peterson97179b02008-09-09 20:55:01 +00001754- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1755 error.
1756
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001757- Issue #3777: long() applied to a float object now always return a long
1758 object; previously an int would be returned for small values. the __long__
1759 method is allowed to return either an int or a long, but the behaviour of
1760 float objects should not change to respect backward compatibility.
1761
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001762- Issue #3751: str.rpartition would perform a left-partition when called with
1763 a unicode argument.
1764
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001765- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001767- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001768 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001769 was correctly parsed but parsing of subsequent arguments failed.
1770
Vinay Sajip35e3b032008-09-01 14:33:59 +00001771- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001772 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1773 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1774 when given a tuple of classes as second argument, were looking up
1775 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1776 type object.
1777
Neal Norwitz18aa3882008-08-24 05:04:52 +00001778- Fix crashes on memory allocation failure found with failmalloc.

1847 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1848 for catch_warnings() also led to an improvement in the raising of a
1849 DeprecationWarning related to warnings.warn_explicit().

1921-----------------
1922
Guido van Rossumf8402962008-08-20 15:01:50 +00001923- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1924 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1925 extensions do not automatically benefit from the class attribute
1926 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1927 to their tp_flags field if they care. This is a backwards
1928 compatibility feature; in 3.0, all types will use the cache by
1929 default.
1930
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001931- Keyword arguments can now follow starred arguments. (``f(a, *args,
1932 keyword=23)`` is now valid syntax.)
1933
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001934- ctypes function pointers that are COM methods have a boolean True
1935 value again.
1936
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001937- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1938 by denying s# to parse objects that have a releasebuffer procedure,
1939 and introducing s*.
1940
Georg Brandl1e13ea92008-08-11 09:07:59 +00001941- Issue #3537: Fix an assertion failure when an empty but presized dict
1942 object was stored in the freelist.
1943
Mark Dickinsonb6467572008-08-04 21:30:09 +00001944- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1945 ValueError consistently across platforms.
1946
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001947- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1948 (64bit Unix, for example), unichr() would truncate its argument and return
1949 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1950
Neal Norwitze7d8be82008-07-31 17:17:14 +00001951- Apply security patches from Apple.
1952
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001953- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1954 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1955
Antoine Pitrou92f82162008-07-25 22:22:08 +00001956- Issue #1819: function calls with several named parameters are now on
1957 average 35% faster (as measured by pybench).
1958
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001959- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1960 the python debugger steps into a class statement: the free variables (local
1961 variables defined in an outer scope) would be deleted from the outer scope.
1962
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001963- Issue #2620: Overflow checking when allocating or reallocating memory
1964 was not always being done properly in some python types and extension
1965 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1966 all been updated to perform better checks and places in the code that
1967 would previously leak memory on the error path when such an allocation
1968 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001973- Issue #3612: Added some missing basic types in ctypes.wintypes.
1974
Benjamin Petersone977ad42008-08-20 01:42:01 +00001975- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1976 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1977
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001978- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1979 version reported by these tools does not necessarily follow the python
1980 version numbering scheme, so the module is less strict when parsing it.
1981
Nick Coghlanf70385a2008-08-18 12:42:46 +00001982- Issue #2235: Added Py3k warnings for types which will become unhashable
1983 under the stricter __hash__ inheritance rules in 3.0. Several types
1984 which did not meet the rules for hash invariants and were already
1985 unhashable in 3.0 have now been explicitly flagged as unhashable in
1986 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

2102
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002103- Issue #643841: The language reference now provides more detailed

2115-----------------
2116
Georg Brandl3e483f62008-07-16 22:57:41 +00002117- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2118 its methods now allow for items objects that can be converted to
2119 an integer using operator.index().
2120
Mark Dickinson64b7e502008-07-16 09:40:03 +00002121- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2122 produced a ValueError instead of giving the correct float.
2123
Eric Smitha5fa5a22008-07-16 00:11:49 +00002124- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2125 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2126
Mark Dickinson7103aa42008-07-15 19:08:33 +00002127- Issue #3008: the float type has a new instance method 'float.hex'
2128 and a new class method 'float.fromhex' to convert floating-point
2129 numbers to and from hexadecimal strings, respectively.
2130
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002131- Issue #2235: __hash__ is once again inherited by default. To allow
2132 collections.Hashable to remain meaningful in the presence of the
2133 default hash implementation (object.__hash__), it is now possible
2134 to explicit block inheritance of hash by setting __hash__=None at
2135 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2136 level.
2137
Nick Coghlanb028f502008-07-13 14:52:36 +00002138- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2139 the parent module cannot be found while performing an absolute import.
2140 This means that an incorrectly defined __package__ attribute will
2141 now only prevent relative imports in that module rather than causing
2142 all imports from that module to fail.
2143
Nick Coghlan14ff9942008-07-08 14:21:42 +00002144- Issue #2517: Allow unicode messages in Exceptions again by correctly

2154 another thread's dictionary.
2155
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002156- Issue #3004: Minor change to slice.indices(): the start and stop
2157 arguments are now treated identically, making the behaviour easier
2158 to describe and understand. For example, slice(None, -10,
2159 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2160 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2161 10, -1).
2162
Georg Brandl278fc502008-07-19 12:46:12 +00002163- Issue #3219: Calling a function with repeated keyword arguments,
2164 f(a=2, a=23), would not cause a syntax error. This was a regression
2165 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002203- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2204 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002205 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002206 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002613- On MacOS X it is now possible to install the framework in 64-bit
2614 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002615 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002616
2617 This is controlled by the configure argument ``--with-universal-archs``:
2618
2619 - ``--with-universal-archs=all``: install 4-way universal
2620
2621 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2622
2623 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2624
2625 This option should be used in combination with ``--enable-universalsdk=``.
2626
2627 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 +00002677- Issue #1631171: Re-implement the 'warnings' module in C (the
2678 original Python code has been kept as backup). This will allow for
2679 using the 'warning's machinery in such places as the parser where
2680 use of pure Python code is not possible. Both the ``showarning()``
2681 and ``formatwarning()`` gain an optional 'line' argument which is
2682 not called by default for backwards-compatibility reasons. Setting
2683 ``warnings.showwarning()`` to an implementation that lacks support
2684 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Issue #2550: The approach used by client/server code for obtaining
2748 ports to listen on in network-oriented tests has been refined in an
2749 effort to facilitate running multiple instances of the entire
2750 regression test suite in parallel without issue.
2751 test_support.bind_port() has been fixed such that it will always
2752 return a unique port -- which wasn't always the case with the
2753 previous implementation, especially if socket options had been set
2754 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2755 new implementation of bind_port() will actually raise an exception
2756 if it is passed an AF_INET/SOCK_STREAM socket with either the
2757 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2758 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2759 the socket it's been passed. This currently only applies to
2760 Windows. This option prevents any other sockets from binding to the
2761 host/port we've bound to, thus removing the possibility of the
2762 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2763 when a second SOCK_STREAM socket binds and accepts to a host/port
2764 that's already been bound by another socket. The optional preferred
2765 port parameter to bind_port() has been removed. Under no
2766 circumstances should tests be hard coding ports!
2767
2768 test_support.find_unused_port() has also been introduced, which will
2769 pass a temporary socket object to bind_port() in order to obtain an
2770 unused port. The temporary socket object is then closed and
2771 deleted, and the port is returned. This method should only be used
2772 for obtaining an unused port in order to pass to an external program
2773 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2774 a parameter to a server-oriented class that doesn't give you direct
2775 access to the underlying socket used.
2776
2777 Finally, test_support.HOST has been introduced, which should be used
2778 for the host argument of any relevant socket calls (i.e. bind and
2779 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002780
2781 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002783 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2784 test_asynchat and test_socket_ssl.
2785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786 It is now possible for multiple instances of the regression test
2787 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002841- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2843 Plane. This affected raw unicode literals and the
2844 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2845 this case, like normal unicode literals and the 'unicode-escape'
2846 codec.

3054-----------------
3055
Fred Drakea8ee94b2008-03-01 02:45:07 +00003056- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003057 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003059- Issue #2067: file.__exit__() now calls subclasses' close() method.
3060
3061- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003062
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003063- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003064 issue 215555 for a discussion.
3065
Eric Smitha73fbe72008-02-23 03:09:44 +00003066- Added the future_builtins module, which contains hex() and oct().
3067 These are the PEP 3127 version of these functions, designed to be
3068 compatible with the hex() and oct() builtins from Python 3.0. They
3069 differ slightly in their output formats from the existing, unchanged
3070 Python 2.6 builtins. The expected usage of the future_builtins
3071 module is:
3072 from future_builtins import hex, oct
3073
Eric Smith7ef40bf2008-02-20 23:34:22 +00003074- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3075 exponents for exponents with absolute value < 100. Follows C99
3076 standard. This is a change on Windows, which would use 3 digits.
3077 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3078 so that any alterations it does to the resulting string will be
3079 available in stringlib/formatter.h (for float.__format__).
3080
Eric Smith5a3c1352008-02-19 13:21:56 +00003081- Implemented PEP 3101, Advanced String Formatting. This adds a new
3082 builtin format(); a format() method for str and unicode; a
3083 __format__() method to object, str, unicode, int, long, float, and
3084 datetime; the class string.Formatter; and the C API
3085 PyObject_Format().
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Fixed several potential crashes, all caused by specially crafted
3088 __del__ methods exploiting objects in temporarily inconsistent
3089 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003090
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003091- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092 prevent a possible crash: an Abstract Base Class would try to access
3093 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003094

Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Clear all free lists during a gc.collect() of the highest generation
3099 in order to allow pymalloc to free more arenas. Python may give back
3100 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Patch #1473257: generator objects gain a gi_code attribute. This is
3133 the same object as the func_code attribute of the function that
3134 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1920: "while 0" statements were completely removed by the
3137 compiler, even in the presence of an "else" clause, which is
3138 supposed to be run when the condition is false. Now the compiler
3139 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003140
Guido van Rossumeead05f2008-01-24 18:21:02 +00003141- A few crashers fixed: weakref_in_del.py (issue #1377858);
3142 loosing_dict_ref.py (issue #1303614, test67.py);
3143 borrowed_ref_[34].py (not in tracker).

3148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003150 several extension methods and modules do not work without unicode
3151 support.
3152
Georg Brandl26543b12008-01-21 18:36:51 +00003153- Issue #1882: when compiling code from a string, encoding cookies in the

3157
Georg Brandl6caad7d2008-01-26 14:19:22 +00003158- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003159 added.
3160
Christian Heimesc94e2b52008-01-14 04:13:37 +00003161- sys.float_info / PyFloat_GetInfo: The floating point information
3162 object was converted from a dict to a specialized structseq object.
3163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Patch #1816: Added sys.flags structseq. It exposes the status of
3165 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Objects/structseq.c: Implemented new structseq representation. The
3168 patch makes structseqs (e.g. the return value of os.stat) more
3169 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Patch #1700288: added a type attribute cache that caches method
3172 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003173
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003174- Bug #1776: __import__() no longer accepts filenames on any platform.
3175 The first parameter to __import__() must be a valid module name.

3180 envvar and sys.dont_write_bytecode attribute. All these can be set
3181 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Improve some exception messages when Windows fails to load an
3184 extension module. Now we get for example '%1 is not a valid Win32
3185 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003186

3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- The enumerate() builtin function is no longer bounded to sequences
3244 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3245 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Issue #1686386: Tuple's tp_repr did not take into account the
3248 possibility of having a self-referential tuple, which is possible
3249 from C code. Nor did object's tp_str consider that a type's tp_str
3250 could do something that could lead to an inifinite recursion.
3251 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3252 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1164: It was possible to trigger deadlock when using the
3255 'print' statement to write to a file since the GIL was not released
3256 as needed. Now PyObject_Print() does the right thing along with
3257 various tp_print implementations of the built-in types and those in
3258 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003268 PyObject_Call() never calling back out to Python code to trigger
3269 recursion depth updates/checks. Required the creation of a static
3270 RuntimeError instance in case normalizing an exception put the
3271 recursion check value past its limit. Fixes crashers

3321 now stricter in rejecting excess arguments. The only time when
3322 either allows excess arguments is when it is not overridden and the
3323 other one is. For backwards compatibility, when both are
3324 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003325 warning later). Also, type.__init__() insists on the same signature
3326 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3329 object to complex using its __complex__() method before falling back
3330 to the __float__() method. Therefore, the functions in the cmath
3331 module now can operate on objects that define a __complex__()
3332 method.

3352
Georg Brandl871f1bc2007-03-12 13:17:36 +00003353- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003354 its argument, if it exists. If not, it will work like before. This
3355 allows customizing the output of dir() in the presence of a
3356 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003368- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369 makes the filenames the warning module prints much more sensible
3370 when a PYTHONSTARTUP file is used.

3384 sq_ass_slice instead of the sq_slice slot.
3385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003438- Bug #1545497: when given an explicit base, int() did ignore NULs
3439 embedded in the string to convert.
3440
Georg Brandl846f73a2006-10-08 07:11:54 +00003441- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003489 generator expressions (x for x, in ... ) works again. Fixing this
3490 problem required changing the .pyc magic number. This means that
3491 .pyc files generated before 2.5c2 will be regenerated.

4296 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004297
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4299 with RFC 3207 and forgets any knowledge obtained from the server not
4300 obtained from the TLS negotiation itself. Patch contributed by Bill
4301 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004304 that the SMTP.starttls() caller no longer needs to call ehlo()
4305 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306 does not claim to support starttls. Adds the
4307 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4308 Fenner.

4388 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4389 silently miscode subclasses of those types. Now, it raises a
4390 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004391

Georg Brandl3ee81df2008-05-17 18:14:43 +00004406 time so that opening a database previously created with the DB_DUP
4407 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4408 opens. Specifically: dictionary assignment to a DB object will
4409 replace all values for a given key when the database allows
4410 duplicate values. DB users should use DB.put(k, v) when they want
4411 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004412

4418 characters with ASCII value less than 32. Also, it correctly quotes
4419 dots only if they occur on a single line, as opposed to the previous
4420 behavior of quoting dots if they are the second character of any
4421 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004422
