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311 code objects if the original filename is obsolete (which can happen if the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
Mark Dickinson1a707982008-12-17 16:14:37 +0000342- Issue #3439: Add a bit_length method to int and long.

345 Original patch by Neal Norwitz.
346
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000347- Issue #4597: Fixed exception handling when the __exit__ function of a
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).

Nick Coghlan49868cb2009-11-15 07:30:34 +0000432- Issue #6816: runpy now provides a run_path function that allows Python code
433 to execute file paths that refer to source or compiled Python files as well
434 as zipfiles, directories and other valid sys.path entries that contain a
435 __main__.py file. This allows applications that run other Python scripts to
436 support the same flexibility as the CPython command line itself.
437
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000438- Issue #7318: multiprocessing now uses a timeout when it fails to establish
439 a connection with another process, rather than looping endlessly. The
440 default timeout is 20 seconds, which should be amply sufficient for
441 local connections.
442
Antoine Pitrou0734c632009-11-10 20:49:30 +0000443- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
444 unpickled. This fixes crashes under Windows when trying to run
445 test_multiprocessing in verbose mode.
446
Antoine Pitroud7158d42009-11-09 16:00:11 +0000447- Issue #7282: Fix a memory leak when an RLock was used in a thread other
448 than those started through `threading.Thread` (for example, using
449 `thread.start_new_thread()`.
450
Antoine Pitrou99c160b2009-11-05 13:42:29 +0000451- Issue #7264: Fix a possible deadlock when deallocating thread-local objects

455 objects on 64-bit systems. Patch by Michael Broghton.
456
Antoine Pitrouaec41242009-11-02 11:34:27 +0000457- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
458 a modification is done through it. This fixes inconsistencies and test
459 failures on systems with slightly bogus mtime behaviour.
460
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000461- Issue #7246 & Issue #7208: getpass now properly flushes input before
462 reading from stdin so that existing input does not confuse it and
463 lead to incorrect entry or an IOError. It also properly flushes it
464 afterwards to avoid the terminal echoing the input afterwards on
465 OSes such as Solaris.
466
Mark Dickinson6f390012009-10-29 12:11:18 +0000467- Issue #7233: Fix a number of two-argument Decimal methods to make
468 sure that they accept an int or long as the second argument. Also
469 fix buggy handling of large arguments (those with coefficient longer
470 than the current precision) in shift and rotate.

1588 leak-chasing test runs give sensible results. The previous method of

1620 can be adjusted to use it over time.

Georg Brandl2bd92a52009-10-11 21:10:07 +00001711- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001712 AttributeError instead of RuntimeError, depending in which C API call
1713 exactly the recursion limit is exceeded. Consequently, both exception types
1714 are caught and silenced.

1730
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001731- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1732
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001733- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1734 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1735 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1736 ``printf`` function, whereas PyString_FromFormat has an independent
1737 implementation and uses "%zd" on all platforms for size_t values.
1738 This makes a difference on win64, where ``printf`` needs "%Id" to display
1739 64bit values.
1740
Benjamin Peterson97179b02008-09-09 20:55:01 +00001741- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1742 error.
1743
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001744- Issue #3777: long() applied to a float object now always return a long
1745 object; previously an int would be returned for small values. the __long__
1746 method is allowed to return either an int or a long, but the behaviour of
1747 float objects should not change to respect backward compatibility.
1748
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001749- Issue #3751: str.rpartition would perform a left-partition when called with
1750 a unicode argument.
1751
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001752- Issue #3683: Fix compilation when --without-threads is given.
1753
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001754- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001755 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001756 was correctly parsed but parsing of subsequent arguments failed.
1757
Vinay Sajip35e3b032008-09-01 14:33:59 +00001758- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001759 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1760 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1761 when given a tuple of classes as second argument, were looking up
1762 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1763 type object.
1764
Neal Norwitz18aa3882008-08-24 05:04:52 +00001765- Fix crashes on memory allocation failure found with failmalloc.
1766
1767- Fix memory leaks found with valgrind and update suppressions file.
1768
1769- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1770
1771- Fix problem using wrong name in decimal module reported by pychecker.
1772
Christian Heimes7d4c3172008-08-22 19:47:25 +00001773- Silenced another compiler warning about a used but not defined
1774 function 'stringlib_contains_obj'.

1777 ``__delslice__``.
1778
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001779- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1780 library targets in the Makefile.
1781
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001782- Issue #1204: The configure script now tests for additional libraries
1783 that may be required when linking against readline. This fixes issues
1784 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1795 stack usage in the case of deeply nested objects.
1796

1806
Nick Coghland2e09382008-09-11 12:11:06 +00001807- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001808 return a list or None rather than a custom object.
1809
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001810- Issue #1638033: Cookie.Morsel gained the httponly attribute.
1811

1834 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1835 for catch_warnings() also led to an improvement in the raising of a
1836 DeprecationWarning related to warnings.warn_explicit().
1837
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001838- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001902What's New in Python 2.6 beta 3?
1903================================
1904
Barry Warsaw07a4a382008-08-21 01:15:08 +00001905*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001906
1907Core and Builtins
1908-----------------
1909
Guido van Rossumf8402962008-08-20 15:01:50 +00001910- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1911 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1912 extensions do not automatically benefit from the class attribute
1913 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1914 to their tp_flags field if they care. This is a backwards
1915 compatibility feature; in 3.0, all types will use the cache by
1916 default.
1917
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001918- Keyword arguments can now follow starred arguments. (``f(a, *args,
1919 keyword=23)`` is now valid syntax.)
1920
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001921- ctypes function pointers that are COM methods have a boolean True
1922 value again.
1923
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001924- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1925 by denying s# to parse objects that have a releasebuffer procedure,
1926 and introducing s*.
1927
Georg Brandl1e13ea92008-08-11 09:07:59 +00001928- Issue #3537: Fix an assertion failure when an empty but presized dict
1929 object was stored in the freelist.
1930
Mark Dickinsonb6467572008-08-04 21:30:09 +00001931- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1932 ValueError consistently across platforms.
1933
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001934- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1935 (64bit Unix, for example), unichr() would truncate its argument and return
1936 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1937
Neal Norwitze7d8be82008-07-31 17:17:14 +00001938- Apply security patches from Apple.
1939
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001940- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1941 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1942
Antoine Pitrou92f82162008-07-25 22:22:08 +00001943- Issue #1819: function calls with several named parameters are now on
1944 average 35% faster (as measured by pybench).
1945
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001946- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1947 the python debugger steps into a class statement: the free variables (local
1948 variables defined in an outer scope) would be deleted from the outer scope.
1949
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001950- Issue #2620: Overflow checking when allocating or reallocating memory
1951 was not always being done properly in some python types and extension
1952 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1953 all been updated to perform better checks and places in the code that
1954 would previously leak memory on the error path when such an allocation
1955 failed have been fixed.

1959
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001960- Issue #3612: Added some missing basic types in ctypes.wintypes.
1961
Benjamin Petersone977ad42008-08-20 01:42:01 +00001962- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1963 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1964
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001965- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1966 version reported by these tools does not necessarily follow the python
1967 version numbering scheme, so the module is less strict when parsing it.
1968
Nick Coghlanf70385a2008-08-18 12:42:46 +00001969- Issue #2235: Added Py3k warnings for types which will become unhashable
1970 under the stricter __hash__ inheritance rules in 3.0. Several types
1971 which did not meet the rules for hash invariants and were already
1972 unhashable in 3.0 have now been explicitly flagged as unhashable in
1973 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1974 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1975
Brett Cannon88f801d2008-08-18 00:46:22 +00001976- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1977 imported into the module but exposed as part of the module's API.
1978
Brett Cannon7b96f072008-08-18 00:41:11 +00001979- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1980
Brett Cannon46225e72008-08-18 00:36:52 +00001981- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1982
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001983- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1984
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001985- Issue #3575: Incremental decoder's decode function now takes bytearray
1986 by using 's*' instead of 't#'.

2102-----------------
2103
Georg Brandl3e483f62008-07-16 22:57:41 +00002104- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2105 its methods now allow for items objects that can be converted to
2106 an integer using operator.index().
2107
Mark Dickinson64b7e502008-07-16 09:40:03 +00002108- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2109 produced a ValueError instead of giving the correct float.
2110
Eric Smitha5fa5a22008-07-16 00:11:49 +00002111- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2112 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2113
Mark Dickinson7103aa42008-07-15 19:08:33 +00002114- Issue #3008: the float type has a new instance method 'float.hex'
2115 and a new class method 'float.fromhex' to convert floating-point
2116 numbers to and from hexadecimal strings, respectively.
2117
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002118- Issue #2235: __hash__ is once again inherited by default. To allow
2119 collections.Hashable to remain meaningful in the presence of the
2120 default hash implementation (object.__hash__), it is now possible
2121 to explicit block inheritance of hash by setting __hash__=None at
2122 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2123 level.
2124
Nick Coghlanb028f502008-07-13 14:52:36 +00002125- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2126 the parent module cannot be found while performing an absolute import.
2127 This means that an incorrectly defined __package__ attribute will
2128 now only prevent relative imports in that module rather than causing
2129 all imports from that module to fail.
2130
Nick Coghlan14ff9942008-07-08 14:21:42 +00002131- Issue #2517: Allow unicode messages in Exceptions again by correctly

2141 another thread's dictionary.
2142
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002143- Issue #3004: Minor change to slice.indices(): the start and stop
2144 arguments are now treated identically, making the behaviour easier
2145 to describe and understand. For example, slice(None, -10,
2146 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2147 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2148 10, -1).
2149
Georg Brandl278fc502008-07-19 12:46:12 +00002150- Issue #3219: Calling a function with repeated keyword arguments,
2151 f(a=2, a=23), would not cause a syntax error. This was a regression
2152 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002154- Issue #2862: Make int and float freelist management consistent with
2155 other freelists. Changes their CompactFreeList apis into

2163 error when they failed.
2164
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002165- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002190- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2191 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002192 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002193 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002209- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002602 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002603
2604 This is controlled by the configure argument ``--with-universal-archs``:
2605
2606 - ``--with-universal-archs=all``: install 4-way universal
2607
2608 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2609
2610 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2611
2612 This option should be used in combination with ``--enable-universalsdk=``.

2665 original Python code has been kept as backup). This will allow for
2666 using the 'warning's machinery in such places as the parser where
2667 use of pure Python code is not possible. Both the ``showarning()``
2668 and ``formatwarning()`` gain an optional 'line' argument which is
2669 not called by default for backwards-compatibility reasons. Setting
2670 ``warnings.showwarning()`` to an implementation that lacks support
2671 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002734- Issue #2550: The approach used by client/server code for obtaining
2735 ports to listen on in network-oriented tests has been refined in an
2736 effort to facilitate running multiple instances of the entire
2737 regression test suite in parallel without issue.
2738 test_support.bind_port() has been fixed such that it will always
2739 return a unique port -- which wasn't always the case with the
2740 previous implementation, especially if socket options had been set
2741 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2742 new implementation of bind_port() will actually raise an exception
2743 if it is passed an AF_INET/SOCK_STREAM socket with either the
2744 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2745 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2746 the socket it's been passed. This currently only applies to
2747 Windows. This option prevents any other sockets from binding to the
2748 host/port we've bound to, thus removing the possibility of the
2749 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2750 when a second SOCK_STREAM socket binds and accepts to a host/port
2751 that's already been bound by another socket. The optional preferred
2752 port parameter to bind_port() has been removed. Under no
2753 circumstances should tests be hard coding ports!
2754
2755 test_support.find_unused_port() has also been introduced, which will
2756 pass a temporary socket object to bind_port() in order to obtain an
2757 unused port. The temporary socket object is then closed and
2758 deleted, and the port is returned. This method should only be used
2759 for obtaining an unused port in order to pass to an external program
2760 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2761 a parameter to a server-oriented class that doesn't give you direct
2762 access to the underlying socket used.
2763
2764 Finally, test_support.HOST has been introduced, which should be used
2765 for the host argument of any relevant socket calls (i.e. bind and
2766 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002767
2768 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002770 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2771 test_asynchat and test_socket_ssl.
2772
Georg Brandl3ee81df2008-05-17 18:14:43 +00002773 It is now possible for multiple instances of the regression test
2774 suite to run in parallel without issue.

2831 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2832 this case, like normal unicode literals and the 'unicode-escape'
2833 codec.

3041-----------------
3042
Fred Drakea8ee94b2008-03-01 02:45:07 +00003043- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003044 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003049
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003050- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003051 issue 215555 for a discussion.
3052
Eric Smitha73fbe72008-02-23 03:09:44 +00003053- Added the future_builtins module, which contains hex() and oct().
3054 These are the PEP 3127 version of these functions, designed to be
3055 compatible with the hex() and oct() builtins from Python 3.0. They
3056 differ slightly in their output formats from the existing, unchanged
3057 Python 2.6 builtins. The expected usage of the future_builtins
3058 module is:
3059 from future_builtins import hex, oct
3060
Eric Smith7ef40bf2008-02-20 23:34:22 +00003061- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3062 exponents for exponents with absolute value < 100. Follows C99
3063 standard. This is a change on Windows, which would use 3 digits.
3064 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3065 so that any alterations it does to the resulting string will be
3066 available in stringlib/formatter.h (for float.__format__).
3067
Eric Smith5a3c1352008-02-19 13:21:56 +00003068- Implemented PEP 3101, Advanced String Formatting. This adds a new
3069 builtin format(); a format() method for str and unicode; a
3070 __format__() method to object, str, unicode, int, long, float, and
3071 datetime; the class string.Formatter; and the C API
3072 PyObject_Format().
3073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Fixed several potential crashes, all caused by specially crafted
3075 __del__ methods exploiting objects in temporarily inconsistent
3076 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003077
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003078- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079 prevent a possible crash: an Abstract Base Class would try to access
3080 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003081
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Fixed repr() and str() of complex numbers with infinity or nan as
3083 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Clear all free lists during a gc.collect() of the highest generation
3086 in order to allow pymalloc to free more arenas. Python may give back
3087 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003088
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Issue #2045: Fix an infinite recursion triggered when printing a
3090 subclass of collections.defaultdict, if its default_factory is set
3091 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3100 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003101 to compact the internal free lists of pre-allocted ints and floats.
3102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3104 calls. Python expected the return type int but the fork familie
3105 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3108 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Patch #1473257: generator objects gain a gi_code attribute. This is
3120 the same object as the func_code attribute of the function that
3121 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Issue #1920: "while 0" statements were completely removed by the
3124 compiler, even in the presence of an "else" clause, which is
3125 supposed to be run when the condition is false. Now the compiler
3126 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003127
Guido van Rossumeead05f2008-01-24 18:21:02 +00003128- A few crashers fixed: weakref_in_del.py (issue #1377858);
3129 loosing_dict_ref.py (issue #1303614, test67.py);
3130 borrowed_ref_[34].py (not in tracker).
3131
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003132- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003133 suppressed while an extension is loaded by calling SetErrorMode in
3134 dynload_win.c. The error is still reported properly.
3135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003137 several extension methods and modules do not work without unicode
3138 support.
3139
Georg Brandl26543b12008-01-21 18:36:51 +00003140- Issue #1882: when compiling code from a string, encoding cookies in the

3144
Georg Brandl6caad7d2008-01-26 14:19:22 +00003145- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003146 added.
3147
Christian Heimesc94e2b52008-01-14 04:13:37 +00003148- sys.float_info / PyFloat_GetInfo: The floating point information
3149 object was converted from a dict to a specialized structseq object.
3150
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Patch #1816: Added sys.flags structseq. It exposes the status of
3152 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Objects/structseq.c: Implemented new structseq representation. The
3155 patch makes structseqs (e.g. the return value of os.stat) more
3156 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Patch #1700288: added a type attribute cache that caches method
3159 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003160
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003161- Bug #1776: __import__() no longer accepts filenames on any platform.
3162 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003163
Georg Brandlaed6c662008-01-07 17:25:53 +00003164- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3165

3167 envvar and sys.dont_write_bytecode attribute. All these can be set
3168 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Improve some exception messages when Windows fails to load an
3171 extension module. Now we get for example '%1 is not a valid Win32
3172 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003173

Christian Heimes0a8143f2007-12-18 23:22:54 +00003179- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180 and INF. float("nan"), float("inf") and float("-inf") now work on
3181 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Compiler now generates simpler and faster code for dictionary
3184 literals. The oparg for BUILD_MAP now indicates an estimated
3185 dictionary size. There is a new opcode, STORE_MAP, for adding
3186 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Patch #1739468: Directories and zipfiles containing a __main__.py
3216 file can now be directly executed by passing their name to the
3217 interpreter. The directory/zipfile is automatically inserted as the
3218 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Issue #1265: Fix a problem with sys.settrace, if the tracing
3221 function uses a generator expression when at the same time the
3222 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003223
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003224- sets and frozensets now have an isdisjoint() method.
3225

3227
Neal Norwitz44f326e2007-10-05 05:29:17 +00003228- Fix warnings found by the new version of the Coverity checker.
3229
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230- The enumerate() builtin function is no longer bounded to sequences
3231 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3232 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Issue #1686386: Tuple's tp_repr did not take into account the
3235 possibility of having a self-referential tuple, which is possible
3236 from C code. Nor did object's tp_str consider that a type's tp_str
3237 could do something that could lead to an inifinite recursion.
3238 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3239 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003240
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- Issue #1164: It was possible to trigger deadlock when using the
3242 'print' statement to write to a file since the GIL was not released
3243 as needed. Now PyObject_Print() does the right thing along with
3244 various tp_print implementations of the built-in types and those in
3245 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Issue #1147: Exceptions were directly allowing string exceptions in
3248 their throw() method even though string exceptions no longer
3249 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Issue #1096: Prevent a segfault from getting the repr of a very
3252 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003253
Brett Cannon1e534b52007-09-07 04:18:30 +00003254- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255 PyObject_Call() never calling back out to Python code to trigger
3256 recursion depth updates/checks. Required the creation of a static
3257 RuntimeError instance in case normalizing an exception put the
3258 recursion check value past its limit. Fixes crashers
3259 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003260

Neal Norwitz0ac60192007-05-27 04:08:54 +00003274- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275 __*__ attributes. (Some already existed, e.g., __doc__ and
3276 __name__.)

3282 calls.
3283
Collin Winter62903052007-05-18 23:11:24 +00003284- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285 "except E as target:". This is to provide forwards compatibility
3286 with Python 3.0.

3292
Vinay Sajip8549ce32007-05-06 17:53:37 +00003293- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003294 setting a plain string, ie don't expand to single letter identifiers.
3295
Raymond Hettinger13936692007-04-11 18:40:58 +00003296- Request #1191699: Slices can now be pickled.
3297
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003298- Request #1193128: str.translate() now allows a None argument for

3300 remaining characters.
3301
Georg Brandl5cb76c12007-03-21 09:00:39 +00003302- Patch #1682205: a TypeError while unpacking an iterable is no longer
3303 masked by a generic one with the message "unpack non-sequence".
3304
Neal Norwitzaa754b72007-03-21 06:39:48 +00003305- Remove unused file Python/fmod.c.
3306
Guido van Rossum143b5642007-03-23 04:58:42 +00003307- Bug #1683368: The object.__init__() and object.__new__() methods are
3308 now stricter in rejecting excess arguments. The only time when
3309 either allows excess arguments is when it is not overridden and the
3310 other one is. For backwards compatibility, when both are
3311 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003312 warning later). Also, type.__init__() insists on the same signature
3313 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3316 object to complex using its __complex__() method before falling back
3317 to the __float__() method. Therefore, the functions in the cmath
3318 module now can operate on objects that define a __complex__()
3319 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003341 its argument, if it exists. If not, it will work like before. This
3342 allows customizing the output of dir() in the presence of a
3343 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003355- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003425- Bug #1545497: when given an explicit base, int() did ignore NULs
3426 embedded in the string to convert.
3427
Georg Brandl846f73a2006-10-08 07:11:54 +00003428- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003458- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003476 generator expressions (x for x, in ... ) works again. Fixing this
3477 problem required changing the .pyc magic number. This means that
3478 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004393 time so that opening a database previously created with the DB_DUP
4394 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4395 opens. Specifically: dictionary assignment to a DB object will
4396 replace all values for a given key when the database allows
4397 duplicate values. DB users should use DB.put(k, v) when they want
4398 to store duplicates; not DB[k] = v.

4405 characters with ASCII value less than 32. Also, it correctly quotes
4406 dots only if they occur on a single line, as opposed to the previous
4407 behavior of quoting dots if they are the second character of any
4408 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004409
