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

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

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

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

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311 code objects if the original filename is obsolete (which can happen if the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

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

411
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000412- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
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).

433 the registry under Windows. Patch by Gabriel Genellina.
434
Nick Coghlan49868cb2009-11-15 07:30:34 +0000435- Issue #6816: runpy now provides a run_path function that allows Python code
436 to execute file paths that refer to source or compiled Python files as well
437 as zipfiles, directories and other valid sys.path entries that contain a
438 __main__.py file. This allows applications that run other Python scripts to
439 support the same flexibility as the CPython command line itself.
440
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000441- Issue #7318: multiprocessing now uses a timeout when it fails to establish
442 a connection with another process, rather than looping endlessly. The
443 default timeout is 20 seconds, which should be amply sufficient for
444 local connections.
445
Antoine Pitrou0734c632009-11-10 20:49:30 +0000446- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

448 test_multiprocessing in verbose mode.
449
Antoine Pitroud7158d42009-11-09 16:00:11 +0000450- Issue #7282: Fix a memory leak when an RLock was used in a thread other

459
Antoine Pitrouaec41242009-11-02 11:34:27 +0000460- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
461 a modification is done through it. This fixes inconsistencies and test
462 failures on systems with slightly bogus mtime behaviour.
463
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000464- Issue #7246 & Issue #7208: getpass now properly flushes input before
465 reading from stdin so that existing input does not confuse it and
466 lead to incorrect entry or an IOError. It also properly flushes it
467 afterwards to avoid the terminal echoing the input afterwards on
468 OSes such as Solaris.

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

Georg Brandl2bd92a52009-10-11 21:10:07 +00001714- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001715 AttributeError instead of RuntimeError, depending in which C API call
1716 exactly the recursion limit is exceeded. Consequently, both exception types
1717 are caught and silenced.

1733
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001734- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1735
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001736- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1737 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1738 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1739 ``printf`` function, whereas PyString_FromFormat has an independent
1740 implementation and uses "%zd" on all platforms for size_t values.
1741 This makes a difference on win64, where ``printf`` needs "%Id" to display
1742 64bit values.
1743
Benjamin Peterson97179b02008-09-09 20:55:01 +00001744- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1745 error.
1746
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001747- Issue #3777: long() applied to a float object now always return a long
1748 object; previously an int would be returned for small values. the __long__
1749 method is allowed to return either an int or a long, but the behaviour of
1750 float objects should not change to respect backward compatibility.
1751
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001752- Issue #3751: str.rpartition would perform a left-partition when called with
1753 a unicode argument.
1754
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001755- Issue #3683: Fix compilation when --without-threads is given.
1756
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001757- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001758 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001759 was correctly parsed but parsing of subsequent arguments failed.
1760
Vinay Sajip35e3b032008-09-01 14:33:59 +00001761- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001762 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1763 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1764 when given a tuple of classes as second argument, were looking up
1765 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1766 type object.
1767
Neal Norwitz18aa3882008-08-24 05:04:52 +00001768- Fix crashes on memory allocation failure found with failmalloc.
1769
1770- Fix memory leaks found with valgrind and update suppressions file.
1771
1772- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1773
1774- Fix problem using wrong name in decimal module reported by pychecker.
1775
Christian Heimes7d4c3172008-08-22 19:47:25 +00001776- Silenced another compiler warning about a used but not defined
1777 function 'stringlib_contains_obj'.
1778

1780 ``__delslice__``.
1781
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001782- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1783 library targets in the Makefile.
1784
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001785- Issue #1204: The configure script now tests for additional libraries
1786 that may be required when linking against readline. This fixes issues
1787 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1798 stack usage in the case of deeply nested objects.
1799

1809
Nick Coghland2e09382008-09-11 12:11:06 +00001810- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001811 return a list or None rather than a custom object.
1812
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001813- Issue #1638033: Cookie.Morsel gained the httponly attribute.
1814
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00001815- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

1837 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1838 for catch_warnings() also led to an improvement in the raising of a
1839 DeprecationWarning related to warnings.warn_explicit().
1840
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001841- The deprecation warnings for the old camelCase threading API were removed.

1866 without limit.
1867
Benjamin Peterson37346b22008-08-23 20:27:43 +00001868- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1869 exploitation of poor argument checking.
1870
Gerhard Häringef2276b2008-09-12 13:54:06 +00001871- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

1884 wrapper for warnings.catch_warnings() that makes it easier to check
1885 that expected warning messages are being reported.
1886

1910Core and Builtins
1911-----------------
1912
Guido van Rossumf8402962008-08-20 15:01:50 +00001913- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1914 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1915 extensions do not automatically benefit from the class attribute
1916 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1917 to their tp_flags field if they care. This is a backwards
1918 compatibility feature; in 3.0, all types will use the cache by
1919 default.
1920
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001921- Keyword arguments can now follow starred arguments. (``f(a, *args,
1922 keyword=23)`` is now valid syntax.)
1923
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001924- ctypes function pointers that are COM methods have a boolean True
1925 value again.
1926
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001927- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1928 by denying s# to parse objects that have a releasebuffer procedure,
1929 and introducing s*.
1930
Georg Brandl1e13ea92008-08-11 09:07:59 +00001931- Issue #3537: Fix an assertion failure when an empty but presized dict
1932 object was stored in the freelist.
1933
Mark Dickinsonb6467572008-08-04 21:30:09 +00001934- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1935 ValueError consistently across platforms.
1936
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001937- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1938 (64bit Unix, for example), unichr() would truncate its argument and return
1939 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1940
Neal Norwitze7d8be82008-07-31 17:17:14 +00001941- Apply security patches from Apple.
1942
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001943- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1944 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1945
Antoine Pitrou92f82162008-07-25 22:22:08 +00001946- Issue #1819: function calls with several named parameters are now on
1947 average 35% faster (as measured by pybench).
1948
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001949- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1950 the python debugger steps into a class statement: the free variables (local
1951 variables defined in an outer scope) would be deleted from the outer scope.
1952
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001953- Issue #2620: Overflow checking when allocating or reallocating memory
1954 was not always being done properly in some python types and extension
1955 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1956 all been updated to perform better checks and places in the code that
1957 would previously leak memory on the error path when such an allocation
1958 failed have been fixed.

1962
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001963- Issue #3612: Added some missing basic types in ctypes.wintypes.
1964
Benjamin Petersone977ad42008-08-20 01:42:01 +00001965- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1966 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1967
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001968- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1969 version reported by these tools does not necessarily follow the python
1970 version numbering scheme, so the module is less strict when parsing it.
1971
Nick Coghlanf70385a2008-08-18 12:42:46 +00001972- Issue #2235: Added Py3k warnings for types which will become unhashable
1973 under the stricter __hash__ inheritance rules in 3.0. Several types
1974 which did not meet the rules for hash invariants and were already
1975 unhashable in 3.0 have now been explicitly flagged as unhashable in
1976 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1977 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1978
Brett Cannon88f801d2008-08-18 00:46:22 +00001979- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1980 imported into the module but exposed as part of the module's API.
1981
Brett Cannon7b96f072008-08-18 00:41:11 +00001982- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1983
Brett Cannon46225e72008-08-18 00:36:52 +00001984- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1985
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001986- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1987
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001988- Issue #3575: Incremental decoder's decode function now takes bytearray

2092
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002093- Issue #643841: The language reference now provides more detailed

2105-----------------
2106
Georg Brandl3e483f62008-07-16 22:57:41 +00002107- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2108 its methods now allow for items objects that can be converted to
2109 an integer using operator.index().
2110
Mark Dickinson64b7e502008-07-16 09:40:03 +00002111- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2112 produced a ValueError instead of giving the correct float.
2113
Eric Smitha5fa5a22008-07-16 00:11:49 +00002114- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2115 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2116
Mark Dickinson7103aa42008-07-15 19:08:33 +00002117- Issue #3008: the float type has a new instance method 'float.hex'
2118 and a new class method 'float.fromhex' to convert floating-point
2119 numbers to and from hexadecimal strings, respectively.
2120
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002121- Issue #2235: __hash__ is once again inherited by default. To allow
2122 collections.Hashable to remain meaningful in the presence of the
2123 default hash implementation (object.__hash__), it is now possible
2124 to explicit block inheritance of hash by setting __hash__=None at
2125 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2126 level.
2127
Nick Coghlanb028f502008-07-13 14:52:36 +00002128- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2129 the parent module cannot be found while performing an absolute import.
2130 This means that an incorrectly defined __package__ attribute will
2131 now only prevent relative imports in that module rather than causing
2132 all imports from that module to fail.
2133
Nick Coghlan14ff9942008-07-08 14:21:42 +00002134- Issue #2517: Allow unicode messages in Exceptions again by correctly

2144 another thread's dictionary.
2145
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002146- Issue #3004: Minor change to slice.indices(): the start and stop
2147 arguments are now treated identically, making the behaviour easier
2148 to describe and understand. For example, slice(None, -10,
2149 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2150 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2151 10, -1).
2152
Georg Brandl278fc502008-07-19 12:46:12 +00002153- Issue #3219: Calling a function with repeated keyword arguments,
2154 f(a=2, a=23), would not cause a syntax error. This was a regression
2155 from 2.4 caused by the switch to the new compiler.

2194 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002195 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002196 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002212- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002605 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002606
2607 This is controlled by the configure argument ``--with-universal-archs``:
2608
2609 - ``--with-universal-archs=all``: install 4-way universal
2610
2611 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2612
2613 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2614
2615 This option should be used in combination with ``--enable-universalsdk=``.

2668 original Python code has been kept as backup). This will allow for
2669 using the 'warning's machinery in such places as the parser where
2670 use of pure Python code is not possible. Both the ``showarning()``
2671 and ``formatwarning()`` gain an optional 'line' argument which is
2672 not called by default for backwards-compatibility reasons. Setting
2673 ``warnings.showwarning()`` to an implementation that lacks support
2674 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- Issue #2550: The approach used by client/server code for obtaining
2738 ports to listen on in network-oriented tests has been refined in an
2739 effort to facilitate running multiple instances of the entire
2740 regression test suite in parallel without issue.
2741 test_support.bind_port() has been fixed such that it will always
2742 return a unique port -- which wasn't always the case with the
2743 previous implementation, especially if socket options had been set
2744 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2745 new implementation of bind_port() will actually raise an exception
2746 if it is passed an AF_INET/SOCK_STREAM socket with either the
2747 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2748 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2749 the socket it's been passed. This currently only applies to
2750 Windows. This option prevents any other sockets from binding to the
2751 host/port we've bound to, thus removing the possibility of the
2752 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2753 when a second SOCK_STREAM socket binds and accepts to a host/port
2754 that's already been bound by another socket. The optional preferred
2755 port parameter to bind_port() has been removed. Under no
2756 circumstances should tests be hard coding ports!
2757
2758 test_support.find_unused_port() has also been introduced, which will
2759 pass a temporary socket object to bind_port() in order to obtain an
2760 unused port. The temporary socket object is then closed and
2761 deleted, and the port is returned. This method should only be used
2762 for obtaining an unused port in order to pass to an external program
2763 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2764 a parameter to a server-oriented class that doesn't give you direct
2765 access to the underlying socket used.
2766
2767 Finally, test_support.HOST has been introduced, which should be used
2768 for the host argument of any relevant socket calls (i.e. bind and
2769 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002770
2771 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002773 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2774 test_asynchat and test_socket_ssl.
2775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776 It is now possible for multiple instances of the regression test
2777 suite to run in parallel without issue.

2834 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2835 this case, like normal unicode literals and the 'unicode-escape'
2836 codec.

3044-----------------
3045
Fred Drakea8ee94b2008-03-01 02:45:07 +00003046- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003047 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003052
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003053- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003054 issue 215555 for a discussion.
3055
Eric Smitha73fbe72008-02-23 03:09:44 +00003056- Added the future_builtins module, which contains hex() and oct().
3057 These are the PEP 3127 version of these functions, designed to be
3058 compatible with the hex() and oct() builtins from Python 3.0. They
3059 differ slightly in their output formats from the existing, unchanged
3060 Python 2.6 builtins. The expected usage of the future_builtins
3061 module is:
3062 from future_builtins import hex, oct
3063
Eric Smith7ef40bf2008-02-20 23:34:22 +00003064- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3065 exponents for exponents with absolute value < 100. Follows C99
3066 standard. This is a change on Windows, which would use 3 digits.
3067 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3068 so that any alterations it does to the resulting string will be
3069 available in stringlib/formatter.h (for float.__format__).
3070
Eric Smith5a3c1352008-02-19 13:21:56 +00003071- Implemented PEP 3101, Advanced String Formatting. This adds a new
3072 builtin format(); a format() method for str and unicode; a
3073 __format__() method to object, str, unicode, int, long, float, and
3074 datetime; the class string.Formatter; and the C API
3075 PyObject_Format().
3076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Fixed several potential crashes, all caused by specially crafted
3078 __del__ methods exploiting objects in temporarily inconsistent
3079 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003080
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003081- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082 prevent a possible crash: an Abstract Base Class would try to access
3083 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Fixed repr() and str() of complex numbers with infinity or nan as
3086 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Clear all free lists during a gc.collect() of the highest generation
3089 in order to allow pymalloc to free more arenas. Python may give back
3090 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003091
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092- Issue #2045: Fix an infinite recursion triggered when printing a
3093 subclass of collections.defaultdict, if its default_factory is set
3094 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3103 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003104 to compact the internal free lists of pre-allocted ints and floats.
3105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3107 calls. Python expected the return type int but the fork familie
3108 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Patch #1473257: generator objects gain a gi_code attribute. This is
3123 the same object as the func_code attribute of the function that
3124 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1920: "while 0" statements were completely removed by the
3127 compiler, even in the presence of an "else" clause, which is
3128 supposed to be run when the condition is false. Now the compiler
3129 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003130
Guido van Rossumeead05f2008-01-24 18:21:02 +00003131- A few crashers fixed: weakref_in_del.py (issue #1377858);
3132 loosing_dict_ref.py (issue #1303614, test67.py);
3133 borrowed_ref_[34].py (not in tracker).
3134
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003135- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003136 suppressed while an extension is loaded by calling SetErrorMode in
3137 dynload_win.c. The error is still reported properly.
3138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003140 several extension methods and modules do not work without unicode
3141 support.
3142
Georg Brandl26543b12008-01-21 18:36:51 +00003143- Issue #1882: when compiling code from a string, encoding cookies in the

3147
Georg Brandl6caad7d2008-01-26 14:19:22 +00003148- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003149 added.
3150
Christian Heimesc94e2b52008-01-14 04:13:37 +00003151- sys.float_info / PyFloat_GetInfo: The floating point information
3152 object was converted from a dict to a specialized structseq object.
3153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Patch #1816: Added sys.flags structseq. It exposes the status of
3155 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Objects/structseq.c: Implemented new structseq representation. The
3158 patch makes structseqs (e.g. the return value of os.stat) more
3159 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1700288: added a type attribute cache that caches method
3162 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003163
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003164- Bug #1776: __import__() no longer accepts filenames on any platform.
3165 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003166

3170 envvar and sys.dont_write_bytecode attribute. All these can be set
3171 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Improve some exception messages when Windows fails to load an
3174 extension module. Now we get for example '%1 is not a valid Win32
3175 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003176

Christian Heimes0a8143f2007-12-18 23:22:54 +00003182- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183 and INF. float("nan"), float("inf") and float("-inf") now work on
3184 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- Compiler now generates simpler and faster code for dictionary
3187 literals. The oparg for BUILD_MAP now indicates an estimated
3188 dictionary size. There is a new opcode, STORE_MAP, for adding
3189 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- Patch #1739468: Directories and zipfiles containing a __main__.py
3219 file can now be directly executed by passing their name to the
3220 interpreter. The directory/zipfile is automatically inserted as the
3221 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Issue #1265: Fix a problem with sys.settrace, if the tracing
3224 function uses a generator expression when at the same time the
3225 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003226
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003227- sets and frozensets now have an isdisjoint() method.
3228

3230
Neal Norwitz44f326e2007-10-05 05:29:17 +00003231- Fix warnings found by the new version of the Coverity checker.
3232
Georg Brandl3ee81df2008-05-17 18:14:43 +00003233- The enumerate() builtin function is no longer bounded to sequences
3234 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3235 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Issue #1686386: Tuple's tp_repr did not take into account the
3238 possibility of having a self-referential tuple, which is possible
3239 from C code. Nor did object's tp_str consider that a type's tp_str
3240 could do something that could lead to an inifinite recursion.
3241 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3242 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Issue #1164: It was possible to trigger deadlock when using the
3245 'print' statement to write to a file since the GIL was not released
3246 as needed. Now PyObject_Print() does the right thing along with
3247 various tp_print implementations of the built-in types and those in
3248 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1147: Exceptions were directly allowing string exceptions in
3251 their throw() method even though string exceptions no longer
3252 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1096: Prevent a segfault from getting the repr of a very
3255 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003256
Brett Cannon1e534b52007-09-07 04:18:30 +00003257- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258 PyObject_Call() never calling back out to Python code to trigger
3259 recursion depth updates/checks. Required the creation of a static
3260 RuntimeError instance in case normalizing an exception put the
3261 recursion check value past its limit. Fixes crashers
3262 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003263

Neal Norwitz0ac60192007-05-27 04:08:54 +00003277- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278 __*__ attributes. (Some already existed, e.g., __doc__ and
3279 __name__.)

3285 calls.
3286
Collin Winter62903052007-05-18 23:11:24 +00003287- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288 "except E as target:". This is to provide forwards compatibility
3289 with Python 3.0.

3295
Vinay Sajip8549ce32007-05-06 17:53:37 +00003296- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003297 setting a plain string, ie don't expand to single letter identifiers.
3298
Raymond Hettinger13936692007-04-11 18:40:58 +00003299- Request #1191699: Slices can now be pickled.
3300
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003301- Request #1193128: str.translate() now allows a None argument for

3303 remaining characters.
3304
Georg Brandl5cb76c12007-03-21 09:00:39 +00003305- Patch #1682205: a TypeError while unpacking an iterable is no longer
3306 masked by a generic one with the message "unpack non-sequence".
3307
Neal Norwitzaa754b72007-03-21 06:39:48 +00003308- Remove unused file Python/fmod.c.
3309
Guido van Rossum143b5642007-03-23 04:58:42 +00003310- Bug #1683368: The object.__init__() and object.__new__() methods are
3311 now stricter in rejecting excess arguments. The only time when
3312 either allows excess arguments is when it is not overridden and the
3313 other one is. For backwards compatibility, when both are
3314 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003315 warning later). Also, type.__init__() insists on the same signature
3316 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3319 object to complex using its __complex__() method before falling back
3320 to the __float__() method. Therefore, the functions in the cmath
3321 module now can operate on objects that define a __complex__()
3322 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003344 its argument, if it exists. If not, it will work like before. This
3345 allows customizing the output of dir() in the presence of a
3346 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003358- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003428- Bug #1545497: when given an explicit base, int() did ignore NULs
3429 embedded in the string to convert.
3430
Georg Brandl846f73a2006-10-08 07:11:54 +00003431- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003461- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003479 generator expressions (x for x, in ... ) works again. Fixing this
3480 problem required changing the .pyc magic number. This means that
3481 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004396 time so that opening a database previously created with the DB_DUP
4397 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4398 opens. Specifically: dictionary assignment to a DB object will
4399 replace all values for a given key when the database allows
4400 duplicate values. DB users should use DB.put(k, v) when they want
4401 to store duplicates; not DB[k] = v.

4408 characters with ASCII value less than 32. Also, it correctly quotes
4409 dots only if they occur on a single line, as opposed to the previous
4410 behavior of quoting dots if they are the second character of any
4411 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004412
