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311 code objects if the original filename is obsolete (which can happen if the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

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

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).

Antoine Pitrouc562ca42009-11-13 22:31:18 +0000432- Issue #7318: multiprocessing now uses a timeout when it fails to establish
433 a connection with another process, rather than looping endlessly. The
434 default timeout is 20 seconds, which should be amply sufficient for
435 local connections.

Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000455- Issue #7246 & Issue #7208: getpass now properly flushes input before
456 reading from stdin so that existing input does not confuse it and
457 lead to incorrect entry or an IOError. It also properly flushes it
458 afterwards to avoid the terminal echoing the input afterwards on
459 OSes such as Solaris.

Mark Dickinson6f390012009-10-29 12:11:18 +0000461- Issue #7233: Fix a number of two-argument Decimal methods to make

1576 leak-chasing test runs give sensible results. The previous method of
1577 reaping threads could return successfully while some Thread objects were

1717-----------------
1718
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001719- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1720
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001721- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1722 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1723 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1724 ``printf`` function, whereas PyString_FromFormat has an independent
1725 implementation and uses "%zd" on all platforms for size_t values.
1726 This makes a difference on win64, where ``printf`` needs "%Id" to display
1727 64bit values.
1728
Benjamin Peterson97179b02008-09-09 20:55:01 +00001729- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1730 error.
1731
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001732- Issue #3777: long() applied to a float object now always return a long
1733 object; previously an int would be returned for small values. the __long__
1734 method is allowed to return either an int or a long, but the behaviour of
1735 float objects should not change to respect backward compatibility.
1736
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001737- Issue #3751: str.rpartition would perform a left-partition when called with
1738 a unicode argument.
1739
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001740- Issue #3683: Fix compilation when --without-threads is given.
1741
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001742- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001743 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001744 was correctly parsed but parsing of subsequent arguments failed.
1745
Vinay Sajip35e3b032008-09-01 14:33:59 +00001746- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001747 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1748 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1749 when given a tuple of classes as second argument, were looking up
1750 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1751 type object.
1752
Neal Norwitz18aa3882008-08-24 05:04:52 +00001753- Fix crashes on memory allocation failure found with failmalloc.
1754
1755- Fix memory leaks found with valgrind and update suppressions file.
1756
1757- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1758
1759- Fix problem using wrong name in decimal module reported by pychecker.
1760
Christian Heimes7d4c3172008-08-22 19:47:25 +00001761- Silenced another compiler warning about a used but not defined
1762 function 'stringlib_contains_obj'.
1763

1765 ``__delslice__``.
1766
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001767- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1768 library targets in the Makefile.
1769
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001770- Issue #1204: The configure script now tests for additional libraries
1771 that may be required when linking against readline. This fixes issues
1772 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001795- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001796 return a list or None rather than a custom object.

1822 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1823 for catch_warnings() also led to an improvement in the raising of a
1824 DeprecationWarning related to warnings.warn_explicit().
1825
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001826- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001890What's New in Python 2.6 beta 3?
1891================================
1892
Barry Warsaw07a4a382008-08-21 01:15:08 +00001893*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001894
1895Core and Builtins
1896-----------------
1897
Guido van Rossumf8402962008-08-20 15:01:50 +00001898- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1899 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1900 extensions do not automatically benefit from the class attribute
1901 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1902 to their tp_flags field if they care. This is a backwards
1903 compatibility feature; in 3.0, all types will use the cache by
1904 default.
1905
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001906- Keyword arguments can now follow starred arguments. (``f(a, *args,
1907 keyword=23)`` is now valid syntax.)
1908
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001909- ctypes function pointers that are COM methods have a boolean True
1910 value again.
1911
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001912- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1913 by denying s# to parse objects that have a releasebuffer procedure,
1914 and introducing s*.
1915
Georg Brandl1e13ea92008-08-11 09:07:59 +00001916- Issue #3537: Fix an assertion failure when an empty but presized dict
1917 object was stored in the freelist.
1918
Mark Dickinsonb6467572008-08-04 21:30:09 +00001919- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1920 ValueError consistently across platforms.
1921
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001922- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1923 (64bit Unix, for example), unichr() would truncate its argument and return
1924 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1925
Neal Norwitze7d8be82008-07-31 17:17:14 +00001926- Apply security patches from Apple.
1927
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001928- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1929 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1930
Antoine Pitrou92f82162008-07-25 22:22:08 +00001931- Issue #1819: function calls with several named parameters are now on
1932 average 35% faster (as measured by pybench).
1933
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001934- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1935 the python debugger steps into a class statement: the free variables (local
1936 variables defined in an outer scope) would be deleted from the outer scope.
1937
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001938- Issue #2620: Overflow checking when allocating or reallocating memory
1939 was not always being done properly in some python types and extension
1940 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1941 all been updated to perform better checks and places in the code that
1942 would previously leak memory on the error path when such an allocation
1943 failed have been fixed.

1951 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1952
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001953- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1954 version reported by these tools does not necessarily follow the python
1955 version numbering scheme, so the module is less strict when parsing it.
1956
Nick Coghlanf70385a2008-08-18 12:42:46 +00001957- Issue #2235: Added Py3k warnings for types which will become unhashable
1958 under the stricter __hash__ inheritance rules in 3.0. Several types
1959 which did not meet the rules for hash invariants and were already
1960 unhashable in 3.0 have now been explicitly flagged as unhashable in
1961 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1962 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1963
Brett Cannon88f801d2008-08-18 00:46:22 +00001964- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1965 imported into the module but exposed as part of the module's API.
1966
Brett Cannon7b96f072008-08-18 00:41:11 +00001967- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001971- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1972
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001973- Issue #3575: Incremental decoder's decode function now takes bytearray
1974 by using 's*' instead of 't#'.
1975
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001976- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001977 fails unicode conversion on 2nd parameter. (windows only)
1978
Facundo Batista94f243a2008-08-17 03:38:39 +00001979- Issue 2464. urllib2 now supports a malformation in the URL received
1980 in a redirect.

2011 to _sre.compile() will now be rejected. This should not affect anybody
2012 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00002033 asking for a specific length. This problem only affected files opened
2034 using the new "io" module, not the built-in open() function.

2077
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002078- Issue #643841: The language reference now provides more detailed

2090-----------------
2091
Georg Brandl3e483f62008-07-16 22:57:41 +00002092- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2093 its methods now allow for items objects that can be converted to
2094 an integer using operator.index().
2095
Mark Dickinson64b7e502008-07-16 09:40:03 +00002096- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2097 produced a ValueError instead of giving the correct float.
2098
Eric Smitha5fa5a22008-07-16 00:11:49 +00002099- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2100 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2101
Mark Dickinson7103aa42008-07-15 19:08:33 +00002102- Issue #3008: the float type has a new instance method 'float.hex'
2103 and a new class method 'float.fromhex' to convert floating-point
2104 numbers to and from hexadecimal strings, respectively.
2105
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002106- Issue #2235: __hash__ is once again inherited by default. To allow
2107 collections.Hashable to remain meaningful in the presence of the
2108 default hash implementation (object.__hash__), it is now possible
2109 to explicit block inheritance of hash by setting __hash__=None at
2110 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2111 level.
2112
Nick Coghlanb028f502008-07-13 14:52:36 +00002113- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2114 the parent module cannot be found while performing an absolute import.
2115 This means that an incorrectly defined __package__ attribute will
2116 now only prevent relative imports in that module rather than causing
2117 all imports from that module to fail.
2118
Nick Coghlan14ff9942008-07-08 14:21:42 +00002119- Issue #2517: Allow unicode messages in Exceptions again by correctly

2129 another thread's dictionary.
2130
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002131- Issue #3004: Minor change to slice.indices(): the start and stop
2132 arguments are now treated identically, making the behaviour easier
2133 to describe and understand. For example, slice(None, -10,
2134 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2135 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2136 10, -1).
2137
Georg Brandl278fc502008-07-19 12:46:12 +00002138- Issue #3219: Calling a function with repeated keyword arguments,
2139 f(a=2, a=23), would not cause a syntax error. This was a regression
2140 from 2.4 caused by the switch to the new compiler.

2152
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002153- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002178- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2179 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002180 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002181 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002197- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2587
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002588- On MacOS X it is now possible to install the framework in 64-bit
2589 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002590 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002591
2592 This is controlled by the configure argument ``--with-universal-archs``:
2593
2594 - ``--with-universal-archs=all``: install 4-way universal
2595
2596 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2597
2598 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2599
2600 This option should be used in combination with ``--enable-universalsdk=``.
2601
2602 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 +00002652- Issue #1631171: Re-implement the 'warnings' module in C (the
2653 original Python code has been kept as backup). This will allow for
2654 using the 'warning's machinery in such places as the parser where
2655 use of pure Python code is not possible. Both the ``showarning()``
2656 and ``formatwarning()`` gain an optional 'line' argument which is
2657 not called by default for backwards-compatibility reasons. Setting
2658 ``warnings.showwarning()`` to an implementation that lacks support
2659 for the ``line`` argument will raise a DeprecationWarning.

2683
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002684- The getpass module has been improved on Unix. It now uses /dev/tty
2685 by default and uses stderr instead of stdout. A GetPassWarning is
2686 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002687

Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002702 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Issue #2550: The approach used by client/server code for obtaining
2723 ports to listen on in network-oriented tests has been refined in an
2724 effort to facilitate running multiple instances of the entire
2725 regression test suite in parallel without issue.
2726 test_support.bind_port() has been fixed such that it will always
2727 return a unique port -- which wasn't always the case with the
2728 previous implementation, especially if socket options had been set
2729 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2730 new implementation of bind_port() will actually raise an exception
2731 if it is passed an AF_INET/SOCK_STREAM socket with either the
2732 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2733 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2734 the socket it's been passed. This currently only applies to
2735 Windows. This option prevents any other sockets from binding to the
2736 host/port we've bound to, thus removing the possibility of the
2737 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2738 when a second SOCK_STREAM socket binds and accepts to a host/port
2739 that's already been bound by another socket. The optional preferred
2740 port parameter to bind_port() has been removed. Under no
2741 circumstances should tests be hard coding ports!
2742
2743 test_support.find_unused_port() has also been introduced, which will
2744 pass a temporary socket object to bind_port() in order to obtain an
2745 unused port. The temporary socket object is then closed and
2746 deleted, and the port is returned. This method should only be used
2747 for obtaining an unused port in order to pass to an external program
2748 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2749 a parameter to a server-oriented class that doesn't give you direct
2750 access to the underlying socket used.
2751
2752 Finally, test_support.HOST has been introduced, which should be used
2753 for the host argument of any relevant socket calls (i.e. bind and
2754 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002755
2756 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002758 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2759 test_asynchat and test_socket_ssl.
2760
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761 It is now possible for multiple instances of the regression test
2762 suite to run in parallel without issue.

3029-----------------
3030
Fred Drakea8ee94b2008-03-01 02:45:07 +00003031- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003032 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003038- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003039 issue 215555 for a discussion.
3040
Eric Smitha73fbe72008-02-23 03:09:44 +00003041- Added the future_builtins module, which contains hex() and oct().
3042 These are the PEP 3127 version of these functions, designed to be
3043 compatible with the hex() and oct() builtins from Python 3.0. They
3044 differ slightly in their output formats from the existing, unchanged
3045 Python 2.6 builtins. The expected usage of the future_builtins
3046 module is:
3047 from future_builtins import hex, oct
3048
Eric Smith7ef40bf2008-02-20 23:34:22 +00003049- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3050 exponents for exponents with absolute value < 100. Follows C99
3051 standard. This is a change on Windows, which would use 3 digits.
3052 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3053 so that any alterations it does to the resulting string will be
3054 available in stringlib/formatter.h (for float.__format__).
3055
Eric Smith5a3c1352008-02-19 13:21:56 +00003056- Implemented PEP 3101, Advanced String Formatting. This adds a new
3057 builtin format(); a format() method for str and unicode; a
3058 __format__() method to object, str, unicode, int, long, float, and
3059 datetime; the class string.Formatter; and the C API
3060 PyObject_Format().
3061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Fixed several potential crashes, all caused by specially crafted
3063 __del__ methods exploiting objects in temporarily inconsistent
3064 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003065
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003066- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003067 prevent a possible crash: an Abstract Base Class would try to access
3068 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003069

3071 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003072
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073- Clear all free lists during a gc.collect() of the highest generation
3074 in order to allow pymalloc to free more arenas. Python may give back

Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Issue #2045: Fix an infinite recursion triggered when printing a
3078 subclass of collections.defaultdict, if its default_factory is set
3079 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003080
Christian Heimesf75dbef2008-02-08 00:11:31 +00003081- Fixed a minor memory leak in dictobject.c. The content of the free
3082 list was not freed on interpreter shutdown.
3083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Limit free list of method and builtin function objects to 256
3085 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3088 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003089 to compact the internal free lists of pre-allocted ints and floats.
3090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3092 calls. Python expected the return type int but the fork familie
3093 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3096 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3099 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3105 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Patch #1473257: generator objects gain a gi_code attribute. This is
3108 the same object as the func_code attribute of the function that
3109 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Issue #1920: "while 0" statements were completely removed by the
3112 compiler, even in the presence of an "else" clause, which is
3113 supposed to be run when the condition is false. Now the compiler
3114 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003115
Guido van Rossumeead05f2008-01-24 18:21:02 +00003116- A few crashers fixed: weakref_in_del.py (issue #1377858);
3117 loosing_dict_ref.py (issue #1303614, test67.py);
3118 borrowed_ref_[34].py (not in tracker).
3119
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003120- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003121 suppressed while an extension is loaded by calling SetErrorMode in
3122 dynload_win.c. The error is still reported properly.
3123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003125 several extension methods and modules do not work without unicode
3126 support.
3127
Georg Brandl26543b12008-01-21 18:36:51 +00003128- Issue #1882: when compiling code from a string, encoding cookies in the
3129 second line of code were not always recognized correctly.
3130
Georg Brandl14404b62008-01-19 19:27:05 +00003131- Issue #1679: "0x" was taken as a valid integer literal.
3132
Georg Brandl6caad7d2008-01-26 14:19:22 +00003133- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003134 added.
3135
Christian Heimesc94e2b52008-01-14 04:13:37 +00003136- sys.float_info / PyFloat_GetInfo: The floating point information
3137 object was converted from a dict to a specialized structseq object.
3138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Patch #1816: Added sys.flags structseq. It exposes the status of
3140 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Objects/structseq.c: Implemented new structseq representation. The
3143 patch makes structseqs (e.g. the return value of os.stat) more
3144 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Patch #1700288: added a type attribute cache that caches method
3147 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003148
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003149- Bug #1776: __import__() no longer accepts filenames on any platform.
3150 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003151

3153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3155 envvar and sys.dont_write_bytecode attribute. All these can be set
3156 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Improve some exception messages when Windows fails to load an
3159 extension module. Now we get for example '%1 is not a valid Win32
3160 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003161

Christian Heimes0a8143f2007-12-18 23:22:54 +00003167- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168 and INF. float("nan"), float("inf") and float("-inf") now work on
3169 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Compiler now generates simpler and faster code for dictionary
3172 literals. The oparg for BUILD_MAP now indicates an estimated
3173 dictionary size. There is a new opcode, STORE_MAP, for adding
3174 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Patch #1739468: Directories and zipfiles containing a __main__.py
3204 file can now be directly executed by passing their name to the
3205 interpreter. The directory/zipfile is automatically inserted as the
3206 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003207
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208- Issue #1265: Fix a problem with sys.settrace, if the tracing
3209 function uses a generator expression when at the same time the
3210 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003211
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003212- sets and frozensets now have an isdisjoint() method.
3213

3215
Neal Norwitz44f326e2007-10-05 05:29:17 +00003216- Fix warnings found by the new version of the Coverity checker.
3217
Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- The enumerate() builtin function is no longer bounded to sequences
3219 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3220 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003221
Georg Brandl3ee81df2008-05-17 18:14:43 +00003222- Issue #1686386: Tuple's tp_repr did not take into account the
3223 possibility of having a self-referential tuple, which is possible
3224 from C code. Nor did object's tp_str consider that a type's tp_str
3225 could do something that could lead to an inifinite recursion.
3226 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3227 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Issue #1164: It was possible to trigger deadlock when using the
3230 'print' statement to write to a file since the GIL was not released
3231 as needed. Now PyObject_Print() does the right thing along with
3232 various tp_print implementations of the built-in types and those in
3233 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #1147: Exceptions were directly allowing string exceptions in
3236 their throw() method even though string exceptions no longer
3237 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- Issue #1096: Prevent a segfault from getting the repr of a very
3240 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003241
Brett Cannon1e534b52007-09-07 04:18:30 +00003242- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243 PyObject_Call() never calling back out to Python code to trigger
3244 recursion depth updates/checks. Required the creation of a static
3245 RuntimeError instance in case normalizing an exception put the
3246 recursion check value past its limit. Fixes crashers
3247 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003248

Neal Norwitz0ac60192007-05-27 04:08:54 +00003262- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003263 __*__ attributes. (Some already existed, e.g., __doc__ and
3264 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003265
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003266- Add -3 option to the interpreter to warn about features that are
3267 deprecated and will be changed/removed in Python 3.0.
3268
Georg Brandl2134e752007-05-21 20:34:16 +00003269- Patch #1686487: you can now pass any mapping after '**' in function
3270 calls.
3271
Collin Winter62903052007-05-18 23:11:24 +00003272- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273 "except E as target:". This is to provide forwards compatibility
3274 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003275
Brett Cannon229cee22007-05-05 01:34:02 +00003276- Deprecate BaseException.message as per PEP 352.
3277
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278- Issue #1303614: don't expose object's __dict__ when the dict is

3280
Vinay Sajip8549ce32007-05-06 17:53:37 +00003281- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003282 setting a plain string, ie don't expand to single letter identifiers.
3283
Raymond Hettinger13936692007-04-11 18:40:58 +00003284- Request #1191699: Slices can now be pickled.
3285
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003286- Request #1193128: str.translate() now allows a None argument for
3287 translations that only remove characters without re-mapping the
3288 remaining characters.
3289
Georg Brandl5cb76c12007-03-21 09:00:39 +00003290- Patch #1682205: a TypeError while unpacking an iterable is no longer
3291 masked by a generic one with the message "unpack non-sequence".
3292
Neal Norwitzaa754b72007-03-21 06:39:48 +00003293- Remove unused file Python/fmod.c.
3294
Guido van Rossum143b5642007-03-23 04:58:42 +00003295- Bug #1683368: The object.__init__() and object.__new__() methods are
3296 now stricter in rejecting excess arguments. The only time when
3297 either allows excess arguments is when it is not overridden and the
3298 other one is. For backwards compatibility, when both are
3299 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003300 warning later). Also, type.__init__() insists on the same signature
3301 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3304 object to complex using its __complex__() method before falling back
3305 to the __float__() method. Therefore, the functions in the cmath
3306 module now can operate on objects that define a __complex__()
3307 method.

3414 embedded in the string to convert.
3415
Georg Brandl846f73a2006-10-08 07:11:54 +00003416- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003896 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00003930- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003931 are set for invalid interpolation sequences that would lead to

3988 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004381 time so that opening a database previously created with the DB_DUP
4382 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4383 opens. Specifically: dictionary assignment to a DB object will
4384 replace all values for a given key when the database allows
4385 duplicate values. DB users should use DB.put(k, v) when they want
4386 to store duplicates; not DB[k] = v.

4393 characters with ASCII value less than 32. Also, it correctly quotes
4394 dots only if they occur on a single line, as opposed to the previous
4395 behavior of quoting dots if they are the second character of any
4396 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004397
