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.

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311 code objects if the original filename is obsolete (which can happen if the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

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.

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).

439
Nick Coghlan49868cb2009-11-15 07:30:34 +0000440- Issue #6816: runpy now provides a run_path function that allows Python code
441 to execute file paths that refer to source or compiled Python files as well
442 as zipfiles, directories and other valid sys.path entries that contain a
443 __main__.py file. This allows applications that run other Python scripts to
444 support the same flexibility as the CPython command line itself.
445
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000446- Issue #7318: multiprocessing now uses a timeout when it fails to establish
447 a connection with another process, rather than looping endlessly. The
448 default timeout is 20 seconds, which should be amply sufficient for
449 local connections.

467 failures on systems with slightly bogus mtime behaviour.
468
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000469- Issue #7246 & Issue #7208: getpass now properly flushes input before
470 reading from stdin so that existing input does not confuse it and
471 lead to incorrect entry or an IOError. It also properly flushes it
472 afterwards to avoid the terminal echoing the input afterwards on
473 OSes such as Solaris.

Mark Dickinson6f390012009-10-29 12:11:18 +0000475- Issue #7233: Fix a number of two-argument Decimal methods to make

Raymond Hettingerecf252a2009-01-27 10:03:04 +00001140 collections.namedtuple() relied on __name__ being defined.
1141

1207 the timestamp in the gzip stream. The default value remains the current time.

1741
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001742- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1743
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001744- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1745 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1746 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1747 ``printf`` function, whereas PyString_FromFormat has an independent
1748 implementation and uses "%zd" on all platforms for size_t values.
1749 This makes a difference on win64, where ``printf`` needs "%Id" to display
1750 64bit values.
1751
Benjamin Peterson97179b02008-09-09 20:55:01 +00001752- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1753 error.
1754
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001755- Issue #3777: long() applied to a float object now always return a long
1756 object; previously an int would be returned for small values. the __long__
1757 method is allowed to return either an int or a long, but the behaviour of
1758 float objects should not change to respect backward compatibility.
1759
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001760- Issue #3751: str.rpartition would perform a left-partition when called with
1761 a unicode argument.
1762
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001763- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001765- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001766 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001767 was correctly parsed but parsing of subsequent arguments failed.
1768
Vinay Sajip35e3b032008-09-01 14:33:59 +00001769- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001770 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1771 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1772 when given a tuple of classes as second argument, were looking up
1773 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1774 type object.
1775
Neal Norwitz18aa3882008-08-24 05:04:52 +00001776- Fix crashes on memory allocation failure found with failmalloc.
1777
1778- Fix memory leaks found with valgrind and update suppressions file.
1779
1780- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Nick Coghland2e09382008-09-11 12:11:06 +00001818- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001819 return a list or None rather than a custom object.

1845 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1846 for catch_warnings() also led to an improvement in the raising of a
1847 DeprecationWarning related to warnings.warn_explicit().

1918Core and Builtins
1919-----------------
1920
Guido van Rossumf8402962008-08-20 15:01:50 +00001921- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1922 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1923 extensions do not automatically benefit from the class attribute
1924 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1925 to their tp_flags field if they care. This is a backwards
1926 compatibility feature; in 3.0, all types will use the cache by
1927 default.
1928
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001929- Keyword arguments can now follow starred arguments. (``f(a, *args,
1930 keyword=23)`` is now valid syntax.)
1931
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001932- ctypes function pointers that are COM methods have a boolean True
1933 value again.
1934
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001935- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1936 by denying s# to parse objects that have a releasebuffer procedure,
1937 and introducing s*.
1938
Georg Brandl1e13ea92008-08-11 09:07:59 +00001939- Issue #3537: Fix an assertion failure when an empty but presized dict
1940 object was stored in the freelist.
1941
Mark Dickinsonb6467572008-08-04 21:30:09 +00001942- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1943 ValueError consistently across platforms.
1944
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001945- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1946 (64bit Unix, for example), unichr() would truncate its argument and return
1947 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1948
Neal Norwitze7d8be82008-07-31 17:17:14 +00001949- Apply security patches from Apple.
1950
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001951- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1952 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1953
Antoine Pitrou92f82162008-07-25 22:22:08 +00001954- Issue #1819: function calls with several named parameters are now on
1955 average 35% faster (as measured by pybench).
1956
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001957- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1958 the python debugger steps into a class statement: the free variables (local
1959 variables defined in an outer scope) would be deleted from the outer scope.
1960
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001961- Issue #2620: Overflow checking when allocating or reallocating memory
1962 was not always being done properly in some python types and extension
1963 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1964 all been updated to perform better checks and places in the code that
1965 would previously leak memory on the error path when such an allocation
1966 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001971- Issue #3612: Added some missing basic types in ctypes.wintypes.
1972
Benjamin Petersone977ad42008-08-20 01:42:01 +00001973- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1974 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1975
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001976- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1977 version reported by these tools does not necessarily follow the python
1978 version numbering scheme, so the module is less strict when parsing it.
1979
Nick Coghlanf70385a2008-08-18 12:42:46 +00001980- Issue #2235: Added Py3k warnings for types which will become unhashable
1981 under the stricter __hash__ inheritance rules in 3.0. Several types
1982 which did not meet the rules for hash invariants and were already
1983 unhashable in 3.0 have now been explicitly flagged as unhashable in
1984 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1985 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1986
Brett Cannon88f801d2008-08-18 00:46:22 +00001987- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1988 imported into the module but exposed as part of the module's API.
1989

2113-----------------
2114
Georg Brandl3e483f62008-07-16 22:57:41 +00002115- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2116 its methods now allow for items objects that can be converted to
2117 an integer using operator.index().
2118
Mark Dickinson64b7e502008-07-16 09:40:03 +00002119- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2120 produced a ValueError instead of giving the correct float.
2121
Eric Smitha5fa5a22008-07-16 00:11:49 +00002122- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2123 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2124
Mark Dickinson7103aa42008-07-15 19:08:33 +00002125- Issue #3008: the float type has a new instance method 'float.hex'
2126 and a new class method 'float.fromhex' to convert floating-point
2127 numbers to and from hexadecimal strings, respectively.
2128
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002129- Issue #2235: __hash__ is once again inherited by default. To allow
2130 collections.Hashable to remain meaningful in the presence of the
2131 default hash implementation (object.__hash__), it is now possible
2132 to explicit block inheritance of hash by setting __hash__=None at
2133 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2134 level.
2135
Nick Coghlanb028f502008-07-13 14:52:36 +00002136- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2137 the parent module cannot be found while performing an absolute import.
2138 This means that an incorrectly defined __package__ attribute will
2139 now only prevent relative imports in that module rather than causing
2140 all imports from that module to fail.
2141
Nick Coghlan14ff9942008-07-08 14:21:42 +00002142- Issue #2517: Allow unicode messages in Exceptions again by correctly

2152 another thread's dictionary.
2153
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002154- Issue #3004: Minor change to slice.indices(): the start and stop
2155 arguments are now treated identically, making the behaviour easier
2156 to describe and understand. For example, slice(None, -10,
2157 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2158 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2159 10, -1).
2160
Georg Brandl278fc502008-07-19 12:46:12 +00002161- Issue #3219: Calling a function with repeated keyword arguments,
2162 f(a=2, a=23), would not cause a syntax error. This was a regression
2163 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002201- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2202 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002203 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002204 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002220- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002611- On MacOS X it is now possible to install the framework in 64-bit
2612 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002613 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002614
2615 This is controlled by the configure argument ``--with-universal-archs``:
2616
2617 - ``--with-universal-archs=all``: install 4-way universal
2618
2619 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2620
2621 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2622
2623 This option should be used in combination with ``--enable-universalsdk=``.
2624
2625 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 +00002675- Issue #1631171: Re-implement the 'warnings' module in C (the
2676 original Python code has been kept as backup). This will allow for
2677 using the 'warning's machinery in such places as the parser where
2678 use of pure Python code is not possible. Both the ``showarning()``
2679 and ``formatwarning()`` gain an optional 'line' argument which is
2680 not called by default for backwards-compatibility reasons. Setting
2681 ``warnings.showwarning()`` to an implementation that lacks support
2682 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #2550: The approach used by client/server code for obtaining
2746 ports to listen on in network-oriented tests has been refined in an
2747 effort to facilitate running multiple instances of the entire
2748 regression test suite in parallel without issue.
2749 test_support.bind_port() has been fixed such that it will always
2750 return a unique port -- which wasn't always the case with the
2751 previous implementation, especially if socket options had been set
2752 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2753 new implementation of bind_port() will actually raise an exception
2754 if it is passed an AF_INET/SOCK_STREAM socket with either the
2755 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2756 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2757 the socket it's been passed. This currently only applies to
2758 Windows. This option prevents any other sockets from binding to the
2759 host/port we've bound to, thus removing the possibility of the
2760 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2761 when a second SOCK_STREAM socket binds and accepts to a host/port
2762 that's already been bound by another socket. The optional preferred
2763 port parameter to bind_port() has been removed. Under no
2764 circumstances should tests be hard coding ports!
2765
2766 test_support.find_unused_port() has also been introduced, which will
2767 pass a temporary socket object to bind_port() in order to obtain an
2768 unused port. The temporary socket object is then closed and
2769 deleted, and the port is returned. This method should only be used
2770 for obtaining an unused port in order to pass to an external program
2771 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2772 a parameter to a server-oriented class that doesn't give you direct
2773 access to the underlying socket used.
2774
2775 Finally, test_support.HOST has been introduced, which should be used
2776 for the host argument of any relevant socket calls (i.e. bind and
2777 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002778
2779 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002781 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2782 test_asynchat and test_socket_ssl.
2783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784 It is now possible for multiple instances of the regression test
2785 suite to run in parallel without issue.

2838
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002839- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2841 Plane. This affected raw unicode literals and the
2842 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2843 this case, like normal unicode literals and the 'unicode-escape'
2844 codec.

3053
Fred Drakea8ee94b2008-03-01 02:45:07 +00003054- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003055 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003061- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003062 issue 215555 for a discussion.
3063
Eric Smitha73fbe72008-02-23 03:09:44 +00003064- Added the future_builtins module, which contains hex() and oct().
3065 These are the PEP 3127 version of these functions, designed to be
3066 compatible with the hex() and oct() builtins from Python 3.0. They
3067 differ slightly in their output formats from the existing, unchanged
3068 Python 2.6 builtins. The expected usage of the future_builtins
3069 module is:
3070 from future_builtins import hex, oct
3071
Eric Smith7ef40bf2008-02-20 23:34:22 +00003072- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3073 exponents for exponents with absolute value < 100. Follows C99
3074 standard. This is a change on Windows, which would use 3 digits.
3075 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3076 so that any alterations it does to the resulting string will be
3077 available in stringlib/formatter.h (for float.__format__).
3078
Eric Smith5a3c1352008-02-19 13:21:56 +00003079- Implemented PEP 3101, Advanced String Formatting. This adds a new
3080 builtin format(); a format() method for str and unicode; a
3081 __format__() method to object, str, unicode, int, long, float, and
3082 datetime; the class string.Formatter; and the C API
3083 PyObject_Format().
3084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Fixed several potential crashes, all caused by specially crafted
3086 __del__ methods exploiting objects in temporarily inconsistent
3087 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003088
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003089- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090 prevent a possible crash: an Abstract Base Class would try to access
3091 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003092

Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Clear all free lists during a gc.collect() of the highest generation
3097 in order to allow pymalloc to free more arenas. Python may give back
3098 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003099
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Issue #2045: Fix an infinite recursion triggered when printing a
3101 subclass of collections.defaultdict, if its default_factory is set
3102 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00003104- Fixed a minor memory leak in dictobject.c. The content of the free
3105 list was not freed on interpreter shutdown.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Limit free list of method and builtin function objects to 256
3108 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3111 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003112 to compact the internal free lists of pre-allocted ints and floats.
3113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3115 calls. Python expected the return type int but the fork familie
3116 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Patch #1473257: generator objects gain a gi_code attribute. This is
3131 the same object as the func_code attribute of the function that
3132 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Issue #1920: "while 0" statements were completely removed by the
3135 compiler, even in the presence of an "else" clause, which is
3136 supposed to be run when the condition is false. Now the compiler
3137 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003138
Guido van Rossumeead05f2008-01-24 18:21:02 +00003139- A few crashers fixed: weakref_in_del.py (issue #1377858);
3140 loosing_dict_ref.py (issue #1303614, test67.py);
3141 borrowed_ref_[34].py (not in tracker).
3142
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003143- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003144 suppressed while an extension is loaded by calling SetErrorMode in
3145 dynload_win.c. The error is still reported properly.
3146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003148 several extension methods and modules do not work without unicode
3149 support.
3150
Georg Brandl26543b12008-01-21 18:36:51 +00003151- Issue #1882: when compiling code from a string, encoding cookies in the

3153
Georg Brandl14404b62008-01-19 19:27:05 +00003154- Issue #1679: "0x" was taken as a valid integer literal.
3155
Georg Brandl6caad7d2008-01-26 14:19:22 +00003156- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003157 added.
3158
Christian Heimesc94e2b52008-01-14 04:13:37 +00003159- sys.float_info / PyFloat_GetInfo: The floating point information
3160 object was converted from a dict to a specialized structseq object.
3161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Patch #1816: Added sys.flags structseq. It exposes the status of
3163 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Objects/structseq.c: Implemented new structseq representation. The
3166 patch makes structseqs (e.g. the return value of os.stat) more
3167 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003168
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Patch #1700288: added a type attribute cache that caches method
3170 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003171
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003172- Bug #1776: __import__() no longer accepts filenames on any platform.
3173 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003174
Georg Brandlaed6c662008-01-07 17:25:53 +00003175- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3176

3178 envvar and sys.dont_write_bytecode attribute. All these can be set
3179 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Improve some exception messages when Windows fails to load an
3182 extension module. Now we get for example '%1 is not a valid Win32
3183 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003184

Christian Heimes0a8143f2007-12-18 23:22:54 +00003190- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 and INF. float("nan"), float("inf") and float("-inf") now work on
3192 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Compiler now generates simpler and faster code for dictionary
3195 literals. The oparg for BUILD_MAP now indicates an estimated
3196 dictionary size. There is a new opcode, STORE_MAP, for adding
3197 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Patch #1739468: Directories and zipfiles containing a __main__.py
3227 file can now be directly executed by passing their name to the
3228 interpreter. The directory/zipfile is automatically inserted as the
3229 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Issue #1265: Fix a problem with sys.settrace, if the tracing
3232 function uses a generator expression when at the same time the
3233 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003234
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003235- sets and frozensets now have an isdisjoint() method.
3236

3240
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- The enumerate() builtin function is no longer bounded to sequences
3242 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3243 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Issue #1686386: Tuple's tp_repr did not take into account the
3246 possibility of having a self-referential tuple, which is possible
3247 from C code. Nor did object's tp_str consider that a type's tp_str
3248 could do something that could lead to an inifinite recursion.
3249 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3250 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003251
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252- Issue #1164: It was possible to trigger deadlock when using the
3253 'print' statement to write to a file since the GIL was not released
3254 as needed. Now PyObject_Print() does the right thing along with
3255 various tp_print implementations of the built-in types and those in
3256 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Issue #1147: Exceptions were directly allowing string exceptions in

3260 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003265- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266 PyObject_Call() never calling back out to Python code to trigger
3267 recursion depth updates/checks. Required the creation of a static
3268 RuntimeError instance in case normalizing an exception put the
3269 recursion check value past its limit. Fixes crashers
3270 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003271

Neal Norwitz0ac60192007-05-27 04:08:54 +00003285- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286 __*__ attributes. (Some already existed, e.g., __doc__ and
3287 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003288
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003289- Add -3 option to the interpreter to warn about features that are

3293 calls.
3294
Collin Winter62903052007-05-18 23:11:24 +00003295- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296 "except E as target:". This is to provide forwards compatibility
3297 with Python 3.0.

3303
Vinay Sajip8549ce32007-05-06 17:53:37 +00003304- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003305 setting a plain string, ie don't expand to single letter identifiers.
3306
Raymond Hettinger13936692007-04-11 18:40:58 +00003307- Request #1191699: Slices can now be pickled.
3308
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003309- Request #1193128: str.translate() now allows a None argument for

3311 remaining characters.
3312
Georg Brandl5cb76c12007-03-21 09:00:39 +00003313- Patch #1682205: a TypeError while unpacking an iterable is no longer
3314 masked by a generic one with the message "unpack non-sequence".
3315
Neal Norwitzaa754b72007-03-21 06:39:48 +00003316- Remove unused file Python/fmod.c.
3317
Guido van Rossum143b5642007-03-23 04:58:42 +00003318- Bug #1683368: The object.__init__() and object.__new__() methods are
3319 now stricter in rejecting excess arguments. The only time when
3320 either allows excess arguments is when it is not overridden and the
3321 other one is. For backwards compatibility, when both are
3322 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003323 warning later). Also, type.__init__() insists on the same signature
3324 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3327 object to complex using its __complex__() method before falling back
3328 to the __float__() method. Therefore, the functions in the cmath
3329 module now can operate on objects that define a __complex__()
3330 method.

3350
Georg Brandl871f1bc2007-03-12 13:17:36 +00003351- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352 its argument, if it exists. If not, it will work like before. This
3353 allows customizing the output of dir() in the presence of a
3354 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003366- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367 makes the filenames the warning module prints much more sensible
3368 when a PYTHONSTARTUP file is used.

3382 sq_ass_slice instead of the sq_slice slot.
3383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003436- Bug #1545497: when given an explicit base, int() did ignore NULs
3437 embedded in the string to convert.
3438
Georg Brandl846f73a2006-10-08 07:11:54 +00003439- Bug #1569998: break inside a try statement (outside a loop) is now
3440 recognized and rejected.
3441

Armin Rigo7ccbca92006-10-04 12:17:45 +00003444- A number of places, including integer negation and absolute value,
3445 were fixed to not rely on undefined behaviour of the C compiler
3446 anymore.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003487 generator expressions (x for x, in ... ) works again. Fixing this
3488 problem required changing the .pyc magic number. This means that
3489 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4297 with RFC 3207 and forgets any knowledge obtained from the server not
4298 obtained from the TLS negotiation itself. Patch contributed by Bill
4299 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004300
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004302 that the SMTP.starttls() caller no longer needs to call ehlo()
4303 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304 does not claim to support starttls. Adds the
4305 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4306 Fenner.

4386 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4387 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004404 time so that opening a database previously created with the DB_DUP
4405 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4406 opens. Specifically: dictionary assignment to a DB object will
4407 replace all values for a given key when the database allows
4408 duplicate values. DB users should use DB.put(k, v) when they want
4409 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004410

4416 characters with ASCII value less than 32. Also, it correctly quotes
4417 dots only if they occur on a single line, as opposed to the previous
4418 behavior of quoting dots if they are the second character of any
4419 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004420
