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311 code objects if the original filename is obsolete (which can happen if the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

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001706 AttributeError instead of RuntimeError, depending in which C API call
1707 exactly the recursion limit is exceeded. Consequently, both exception types
1708 are caught and silenced.

1723-----------------
1724
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001725- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1726
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001727- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1728 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1729 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1730 ``printf`` function, whereas PyString_FromFormat has an independent
1731 implementation and uses "%zd" on all platforms for size_t values.
1732 This makes a difference on win64, where ``printf`` needs "%Id" to display
1733 64bit values.
1734
Benjamin Peterson97179b02008-09-09 20:55:01 +00001735- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1736 error.
1737
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001738- Issue #3777: long() applied to a float object now always return a long
1739 object; previously an int would be returned for small values. the __long__
1740 method is allowed to return either an int or a long, but the behaviour of
1741 float objects should not change to respect backward compatibility.
1742
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001743- Issue #3751: str.rpartition would perform a left-partition when called with
1744 a unicode argument.
1745
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001746- Issue #3683: Fix compilation when --without-threads is given.
1747
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001748- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001749 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001750 was correctly parsed but parsing of subsequent arguments failed.
1751
Vinay Sajip35e3b032008-09-01 14:33:59 +00001752- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001753 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1754 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1755 when given a tuple of classes as second argument, were looking up
1756 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1757 type object.
1758
Neal Norwitz18aa3882008-08-24 05:04:52 +00001759- Fix crashes on memory allocation failure found with failmalloc.
1760
1761- Fix memory leaks found with valgrind and update suppressions file.
1762
1763- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1764
1765- Fix problem using wrong name in decimal module reported by pychecker.
1766
Christian Heimes7d4c3172008-08-22 19:47:25 +00001767- Silenced another compiler warning about a used but not defined
1768 function 'stringlib_contains_obj'.

1771 ``__delslice__``.
1772
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001773- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1774 library targets in the Makefile.
1775
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001776- Issue #1204: The configure script now tests for additional libraries
1777 that may be required when linking against readline. This fixes issues
1778 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001801- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001802 return a list or None rather than a custom object.
1803
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001804- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1828 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1829 for catch_warnings() also led to an improvement in the raising of a
1830 DeprecationWarning related to warnings.warn_explicit().
1831
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001832- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001896What's New in Python 2.6 beta 3?
1897================================
1898
Barry Warsaw07a4a382008-08-21 01:15:08 +00001899*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001900
1901Core and Builtins
1902-----------------
1903
Guido van Rossumf8402962008-08-20 15:01:50 +00001904- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1905 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1906 extensions do not automatically benefit from the class attribute
1907 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1908 to their tp_flags field if they care. This is a backwards
1909 compatibility feature; in 3.0, all types will use the cache by
1910 default.
1911
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001912- Keyword arguments can now follow starred arguments. (``f(a, *args,
1913 keyword=23)`` is now valid syntax.)
1914
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001915- ctypes function pointers that are COM methods have a boolean True
1916 value again.
1917
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001918- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1919 by denying s# to parse objects that have a releasebuffer procedure,
1920 and introducing s*.
1921
Georg Brandl1e13ea92008-08-11 09:07:59 +00001922- Issue #3537: Fix an assertion failure when an empty but presized dict
1923 object was stored in the freelist.
1924
Mark Dickinsonb6467572008-08-04 21:30:09 +00001925- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1926 ValueError consistently across platforms.
1927
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001928- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1929 (64bit Unix, for example), unichr() would truncate its argument and return
1930 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1931
Neal Norwitze7d8be82008-07-31 17:17:14 +00001932- Apply security patches from Apple.
1933
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001934- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1935 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1936
Antoine Pitrou92f82162008-07-25 22:22:08 +00001937- Issue #1819: function calls with several named parameters are now on
1938 average 35% faster (as measured by pybench).
1939
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001940- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1941 the python debugger steps into a class statement: the free variables (local
1942 variables defined in an outer scope) would be deleted from the outer scope.
1943
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001944- Issue #2620: Overflow checking when allocating or reallocating memory
1945 was not always being done properly in some python types and extension
1946 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1947 all been updated to perform better checks and places in the code that
1948 would previously leak memory on the error path when such an allocation
1949 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00001956- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1957 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1958
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001959- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1960 version reported by these tools does not necessarily follow the python
1961 version numbering scheme, so the module is less strict when parsing it.
1962
Nick Coghlanf70385a2008-08-18 12:42:46 +00001963- Issue #2235: Added Py3k warnings for types which will become unhashable
1964 under the stricter __hash__ inheritance rules in 3.0. Several types
1965 which did not meet the rules for hash invariants and were already
1966 unhashable in 3.0 have now been explicitly flagged as unhashable in
1967 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1968 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1969
Brett Cannon88f801d2008-08-18 00:46:22 +00001970- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1971 imported into the module but exposed as part of the module's API.
1972
Brett Cannon7b96f072008-08-18 00:41:11 +00001973- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001977- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1978
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001979- Issue #3575: Incremental decoder's decode function now takes bytearray
1980 by using 's*' instead of 't#'.
1981
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001982- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001983 fails unicode conversion on 2nd parameter. (windows only)
1984
Facundo Batista94f243a2008-08-17 03:38:39 +00001985- Issue 2464. urllib2 now supports a malformation in the URL received
1986 in a redirect.

Antoine Pitroude781a42008-08-09 12:43:23 +00002039 asking for a specific length. This problem only affected files opened

2083
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002084- Issue #643841: The language reference now provides more detailed

2096-----------------
2097
Georg Brandl3e483f62008-07-16 22:57:41 +00002098- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2099 its methods now allow for items objects that can be converted to
2100 an integer using operator.index().
2101
Mark Dickinson64b7e502008-07-16 09:40:03 +00002102- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2103 produced a ValueError instead of giving the correct float.
2104
Eric Smitha5fa5a22008-07-16 00:11:49 +00002105- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2106 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2107
Mark Dickinson7103aa42008-07-15 19:08:33 +00002108- Issue #3008: the float type has a new instance method 'float.hex'
2109 and a new class method 'float.fromhex' to convert floating-point
2110 numbers to and from hexadecimal strings, respectively.
2111
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002112- Issue #2235: __hash__ is once again inherited by default. To allow
2113 collections.Hashable to remain meaningful in the presence of the
2114 default hash implementation (object.__hash__), it is now possible
2115 to explicit block inheritance of hash by setting __hash__=None at
2116 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2117 level.
2118
Nick Coghlanb028f502008-07-13 14:52:36 +00002119- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2120 the parent module cannot be found while performing an absolute import.
2121 This means that an incorrectly defined __package__ attribute will
2122 now only prevent relative imports in that module rather than causing
2123 all imports from that module to fail.
2124
Nick Coghlan14ff9942008-07-08 14:21:42 +00002125- Issue #2517: Allow unicode messages in Exceptions again by correctly

2135 another thread's dictionary.
2136
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002137- Issue #3004: Minor change to slice.indices(): the start and stop
2138 arguments are now treated identically, making the behaviour easier
2139 to describe and understand. For example, slice(None, -10,
2140 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2141 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2142 10, -1).
2143
Georg Brandl278fc502008-07-19 12:46:12 +00002144- Issue #3219: Calling a function with repeated keyword arguments,
2145 f(a=2, a=23), would not cause a syntax error. This was a regression
2146 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002148- Issue #2862: Make int and float freelist management consistent with
2149 other freelists. Changes their CompactFreeList apis into

2157 error when they failed.
2158
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002159- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002184- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2185 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002186 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002187 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002203- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2593
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002594- On MacOS X it is now possible to install the framework in 64-bit
2595 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002596 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002597
2598 This is controlled by the configure argument ``--with-universal-archs``:
2599
2600 - ``--with-universal-archs=all``: install 4-way universal
2601
2602 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2603
2604 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2605
2606 This option should be used in combination with ``--enable-universalsdk=``.
2607
2608 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 +00002658- Issue #1631171: Re-implement the 'warnings' module in C (the
2659 original Python code has been kept as backup). This will allow for
2660 using the 'warning's machinery in such places as the parser where
2661 use of pure Python code is not possible. Both the ``showarning()``
2662 and ``formatwarning()`` gain an optional 'line' argument which is
2663 not called by default for backwards-compatibility reasons. Setting
2664 ``warnings.showwarning()`` to an implementation that lacks support
2665 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002690- The getpass module has been improved on Unix. It now uses /dev/tty
2691 by default and uses stderr instead of stdout. A GetPassWarning is
2692 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002708 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Issue #2550: The approach used by client/server code for obtaining
2729 ports to listen on in network-oriented tests has been refined in an
2730 effort to facilitate running multiple instances of the entire
2731 regression test suite in parallel without issue.
2732 test_support.bind_port() has been fixed such that it will always
2733 return a unique port -- which wasn't always the case with the
2734 previous implementation, especially if socket options had been set
2735 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2736 new implementation of bind_port() will actually raise an exception
2737 if it is passed an AF_INET/SOCK_STREAM socket with either the
2738 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2739 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2740 the socket it's been passed. This currently only applies to
2741 Windows. This option prevents any other sockets from binding to the
2742 host/port we've bound to, thus removing the possibility of the
2743 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2744 when a second SOCK_STREAM socket binds and accepts to a host/port
2745 that's already been bound by another socket. The optional preferred
2746 port parameter to bind_port() has been removed. Under no
2747 circumstances should tests be hard coding ports!
2748
2749 test_support.find_unused_port() has also been introduced, which will
2750 pass a temporary socket object to bind_port() in order to obtain an
2751 unused port. The temporary socket object is then closed and
2752 deleted, and the port is returned. This method should only be used
2753 for obtaining an unused port in order to pass to an external program
2754 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2755 a parameter to a server-oriented class that doesn't give you direct
2756 access to the underlying socket used.
2757
2758 Finally, test_support.HOST has been introduced, which should be used
2759 for the host argument of any relevant socket calls (i.e. bind and
2760 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002761
2762 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002764 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2765 test_asynchat and test_socket_ssl.
2766
Georg Brandl3ee81df2008-05-17 18:14:43 +00002767 It is now possible for multiple instances of the regression test
2768 suite to run in parallel without issue.

3035-----------------
3036
Fred Drakea8ee94b2008-03-01 02:45:07 +00003037- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003038 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003043
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003044- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003045 issue 215555 for a discussion.
3046
Eric Smitha73fbe72008-02-23 03:09:44 +00003047- Added the future_builtins module, which contains hex() and oct().
3048 These are the PEP 3127 version of these functions, designed to be
3049 compatible with the hex() and oct() builtins from Python 3.0. They
3050 differ slightly in their output formats from the existing, unchanged
3051 Python 2.6 builtins. The expected usage of the future_builtins
3052 module is:
3053 from future_builtins import hex, oct
3054
Eric Smith7ef40bf2008-02-20 23:34:22 +00003055- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3056 exponents for exponents with absolute value < 100. Follows C99
3057 standard. This is a change on Windows, which would use 3 digits.
3058 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3059 so that any alterations it does to the resulting string will be
3060 available in stringlib/formatter.h (for float.__format__).
3061
Eric Smith5a3c1352008-02-19 13:21:56 +00003062- Implemented PEP 3101, Advanced String Formatting. This adds a new
3063 builtin format(); a format() method for str and unicode; a
3064 __format__() method to object, str, unicode, int, long, float, and
3065 datetime; the class string.Formatter; and the C API
3066 PyObject_Format().
3067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Fixed several potential crashes, all caused by specially crafted
3069 __del__ methods exploiting objects in temporarily inconsistent
3070 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003071
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003072- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073 prevent a possible crash: an Abstract Base Class would try to access
3074 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003075

Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Clear all free lists during a gc.collect() of the highest generation
3080 in order to allow pymalloc to free more arenas. Python may give back
3081 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Issue #2045: Fix an infinite recursion triggered when printing a
3084 subclass of collections.defaultdict, if its default_factory is set
3085 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003086
Christian Heimesf75dbef2008-02-08 00:11:31 +00003087- Fixed a minor memory leak in dictobject.c. The content of the free
3088 list was not freed on interpreter shutdown.
3089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Limit free list of method and builtin function objects to 256
3091 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3094 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003095 to compact the internal free lists of pre-allocted ints and floats.
3096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3098 calls. Python expected the return type int but the fork familie
3099 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3102 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3111 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Patch #1473257: generator objects gain a gi_code attribute. This is
3114 the same object as the func_code attribute of the function that
3115 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003116
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1920: "while 0" statements were completely removed by the
3118 compiler, even in the presence of an "else" clause, which is
3119 supposed to be run when the condition is false. Now the compiler
3120 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003121
Guido van Rossumeead05f2008-01-24 18:21:02 +00003122- A few crashers fixed: weakref_in_del.py (issue #1377858);
3123 loosing_dict_ref.py (issue #1303614, test67.py);
3124 borrowed_ref_[34].py (not in tracker).
3125
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003126- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003127 suppressed while an extension is loaded by calling SetErrorMode in
3128 dynload_win.c. The error is still reported properly.
3129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003131 several extension methods and modules do not work without unicode
3132 support.
3133
Georg Brandl26543b12008-01-21 18:36:51 +00003134- Issue #1882: when compiling code from a string, encoding cookies in the

3138
Georg Brandl6caad7d2008-01-26 14:19:22 +00003139- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003140 added.
3141
Christian Heimesc94e2b52008-01-14 04:13:37 +00003142- sys.float_info / PyFloat_GetInfo: The floating point information
3143 object was converted from a dict to a specialized structseq object.
3144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Patch #1816: Added sys.flags structseq. It exposes the status of
3146 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Objects/structseq.c: Implemented new structseq representation. The
3149 patch makes structseqs (e.g. the return value of os.stat) more
3150 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003151
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Patch #1700288: added a type attribute cache that caches method
3153 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003154
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003155- Bug #1776: __import__() no longer accepts filenames on any platform.
3156 The first parameter to __import__() must be a valid module name.

3161 envvar and sys.dont_write_bytecode attribute. All these can be set
3162 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Improve some exception messages when Windows fails to load an
3165 extension module. Now we get for example '%1 is not a valid Win32
3166 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003167

Christian Heimes0a8143f2007-12-18 23:22:54 +00003173- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174 and INF. float("nan"), float("inf") and float("-inf") now work on
3175 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Compiler now generates simpler and faster code for dictionary
3178 literals. The oparg for BUILD_MAP now indicates an estimated
3179 dictionary size. There is a new opcode, STORE_MAP, for adding
3180 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003209- Patch #1739468: Directories and zipfiles containing a __main__.py
3210 file can now be directly executed by passing their name to the
3211 interpreter. The directory/zipfile is automatically inserted as the
3212 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003214- Issue #1265: Fix a problem with sys.settrace, if the tracing
3215 function uses a generator expression when at the same time the
3216 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003217
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003218- sets and frozensets now have an isdisjoint() method.

3221
Neal Norwitz44f326e2007-10-05 05:29:17 +00003222- Fix warnings found by the new version of the Coverity checker.
3223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- The enumerate() builtin function is no longer bounded to sequences
3225 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3226 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003227
Georg Brandl3ee81df2008-05-17 18:14:43 +00003228- Issue #1686386: Tuple's tp_repr did not take into account the
3229 possibility of having a self-referential tuple, which is possible
3230 from C code. Nor did object's tp_str consider that a type's tp_str
3231 could do something that could lead to an inifinite recursion.
3232 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3233 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #1164: It was possible to trigger deadlock when using the
3236 'print' statement to write to a file since the GIL was not released
3237 as needed. Now PyObject_Print() does the right thing along with
3238 various tp_print implementations of the built-in types and those in
3239 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003240
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- Issue #1147: Exceptions were directly allowing string exceptions in
3242 their throw() method even though string exceptions no longer
3243 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003247
Brett Cannon1e534b52007-09-07 04:18:30 +00003248- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249 PyObject_Call() never calling back out to Python code to trigger
3250 recursion depth updates/checks. Required the creation of a static
3251 RuntimeError instance in case normalizing an exception put the
3252 recursion check value past its limit. Fixes crashers
3253 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003254

Neal Norwitz0ac60192007-05-27 04:08:54 +00003268- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269 __*__ attributes. (Some already existed, e.g., __doc__ and
3270 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003271
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003272- Add -3 option to the interpreter to warn about features that are

3276 calls.
3277
Collin Winter62903052007-05-18 23:11:24 +00003278- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003279 "except E as target:". This is to provide forwards compatibility
3280 with Python 3.0.

3286
Vinay Sajip8549ce32007-05-06 17:53:37 +00003287- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003288 setting a plain string, ie don't expand to single letter identifiers.
3289
Raymond Hettinger13936692007-04-11 18:40:58 +00003290- Request #1191699: Slices can now be pickled.
3291
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003292- Request #1193128: str.translate() now allows a None argument for

3294 remaining characters.
3295
Georg Brandl5cb76c12007-03-21 09:00:39 +00003296- Patch #1682205: a TypeError while unpacking an iterable is no longer
3297 masked by a generic one with the message "unpack non-sequence".
3298
Neal Norwitzaa754b72007-03-21 06:39:48 +00003299- Remove unused file Python/fmod.c.
3300
Guido van Rossum143b5642007-03-23 04:58:42 +00003301- Bug #1683368: The object.__init__() and object.__new__() methods are
3302 now stricter in rejecting excess arguments. The only time when
3303 either allows excess arguments is when it is not overridden and the
3304 other one is. For backwards compatibility, when both are
3305 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003306 warning later). Also, type.__init__() insists on the same signature
3307 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3310 object to complex using its __complex__() method before falling back
3311 to the __float__() method. Therefore, the functions in the cmath
3312 module now can operate on objects that define a __complex__()
3313 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003335 its argument, if it exists. If not, it will work like before. This
3336 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00003349- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003419- Bug #1545497: when given an explicit base, int() did ignore NULs
3420 embedded in the string to convert.
3421
Georg Brandl846f73a2006-10-08 07:11:54 +00003422- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003452- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003470 generator expressions (x for x, in ... ) works again. Fixing this
3471 problem required changing the .pyc magic number. This means that
3472 .pyc files generated before 2.5c2 will be regenerated.

3994 TestCase and TestSuite subclasses (not instances) are no longer

4369 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4370 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004387 time so that opening a database previously created with the DB_DUP
4388 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4389 opens. Specifically: dictionary assignment to a DB object will
4390 replace all values for a given key when the database allows
4391 duplicate values. DB users should use DB.put(k, v) when they want
4392 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004393

4399 characters with ASCII value less than 32. Also, it correctly quotes
4400 dots only if they occur on a single line, as opposed to the previous
4401 behavior of quoting dots if they are the second character of any
4402 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004403

4432 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00004433
