1764What's New in Python 2.6.1
1765==========================
1766
1767*Release date: 04-Dec-2008*
1768
1769Core and Builtins
1770-----------------
1771
1772- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1773 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1774 instead of throwing a MemoryError.
1775
1776- Issue #4367: Python would segfault during compiling when the unicodedata
1777 module couldn't be imported and \N escapes were present.
1778
1779- Issue #4348: Some bytearray methods returned that didn't cause any change to
1780 the bytearray, returned the same bytearray instead of a copy.
1781
1782- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1783
1784- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1785
1786- Issue #4048: The parser module now correctly validates relative imports.
1787
1788- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1789 exec statement.
1790

1792 method does not return iterators for the 4th and 5th items.
1793
1794- Issue #4209: Enabling unicode_literals and the print_function in the same
1795 __future__ import didn't work.
1796
1797- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1798 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1799 really executed because I cannot move to such directory on win2k)
1800
1801- Issue #4069: When set.remove(element) is used with a set element, the element
1802 is temporarily replaced with an equivalent frozenset. But the eventual
1803 KeyError would always report the empty frozenset([]) as the missing key. Now
1804 it correctly refers to the initial element.
1805
1806- Fixed C99 style comments in several files. Python is now C89 compatible
1807 again.

1955
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001956- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1957 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1958 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1959 ``printf`` function, whereas PyString_FromFormat has an independent
1960 implementation and uses "%zd" on all platforms for size_t values.
1961 This makes a difference on win64, where ``printf`` needs "%Id" to display
1962 64bit values.

1968 object; previously an int would be returned for small values. the __long__
1969 method is allowed to return either an int or a long, but the behaviour of
1970 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001981- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001982 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1983 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1984 when given a tuple of classes as second argument, were looking up
1985 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1986 type object.

2128-----------------
2129
Guido van Rossumf8402962008-08-20 15:01:50 +00002130- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2131 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2132 extensions do not automatically benefit from the class attribute
2133 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2134 to their tp_flags field if they care. This is a backwards
2135 compatibility feature; in 3.0, all types will use the cache by
2136 default.
2137
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002138- Keyword arguments can now follow starred arguments. (``f(a, *args,

2140
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002141- ctypes function pointers that are COM methods have a boolean True
2142 value again.

2153
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002154- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2155 (64bit Unix, for example), unichr() would truncate its argument and return
2156 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002160- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2161 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2162
Antoine Pitrou92f82162008-07-25 22:22:08 +00002163- Issue #1819: function calls with several named parameters are now on
2164 average 35% faster (as measured by pybench).
2165
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002166- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2167 the python debugger steps into a class statement: the free variables (local
2168 variables defined in an outer scope) would be deleted from the outer scope.
2169
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002170- Issue #2620: Overflow checking when allocating or reallocating memory
2171 was not always being done properly in some python types and extension
2172 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2173 all been updated to perform better checks and places in the code that
2174 would previously leak memory on the error path when such an allocation
2175 failed have been fixed.

2181
Benjamin Petersone977ad42008-08-20 01:42:01 +00002182- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2183 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2184
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002185- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2186 version reported by these tools does not necessarily follow the python
2187 version numbering scheme, so the module is less strict when parsing it.
2188
Nick Coghlanf70385a2008-08-18 12:42:46 +00002189- Issue #2235: Added Py3k warnings for types which will become unhashable
2190 under the stricter __hash__ inheritance rules in 3.0. Several types
2191 which did not meet the rules for hash invariants and were already
2192 unhashable in 3.0 have now been explicitly flagged as unhashable in
2193 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2194 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2195
Brett Cannon88f801d2008-08-18 00:46:22 +00002196- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2197 imported into the module but exposed as part of the module's API.
2198

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002205- Issue #3575: Incremental decoder's decode function now takes bytearray
2206 by using 's*' instead of 't#'.
2207
Jesus Cea585ad8a2009-07-02 15:37:21 +00002208- Issue #2222: Fixed reference leak when occurred os.rename()

2218 after a 302 response in the case of not going through a proxy.
2219
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002220- Issue #2676: in the email package, content-type parsing was hanging on
2221 pathological input because of quadratic or exponential behaviour of a
2222 regular expression.
2223
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002224- Issue #3476: binary buffered reading through the new "io" library is now
2225 thread-safe.
2226
Brett Cannonbf3157b2008-08-14 05:00:03 +00002227- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2228 since mimetools itself is deprecated. Because modules are cached, all
2229 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2230
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002231- Issue #3134: shutil referenced undefined WindowsError symbol.

2238
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002239- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2240 a MemoryError rather than silently stop the iteration.
2241
Guido van Rossum59ce9012008-08-09 14:55:34 +00002242- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2243 to _sre.compile() will now be rejected. This should not affect anybody
2244 since the re.compile() function never generates invalid re-bytecode.
2245
Skip Montanaroa032bf42008-08-08 22:52:51 +00002246- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2247 upon first access it can be automatically initialized from the csv file if
2248 it wasn't initialized during instantiation.
2249
Brett Cannon3aa2a492008-08-06 22:28:09 +00002250- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2251 the reload() built-in has been removed.
2252
Brett Cannon7e30b672008-08-04 21:52:25 +00002253- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002254 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2262 raised an AttributeError.
2263
Benjamin Peterson01a24322008-07-28 23:35:27 +00002264- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002265 asking for a specific length. This problem only affected files opened
2266 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002267

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002291- Issue #3394: zipfile.writestr sets external attributes when passed a
2292 file name rather than a ZipInfo instance, so files are extracted with
2293 mode 0600 rather than 000 under Unix.
2294
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002295- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2296 argument in python 2.5, this broke code that subclassed Popen to include its
2297 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002307- Issue #2235: the C API function PyObject_HashNotImplemented and its
2308 interaction with the tp_hash slot (added in 2.6b2) are now documented
2309
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002310- Issue #643841: The language reference now provides more detailed
2311 coverage of the lookup process for special methods. The disclaimers
2312 regarding lack of coverage of new-style classes have also been
2313 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002316What's New in Python 2.6 beta 2?
2317================================
2318
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002319*Release date: 17-Jul-2008*
2320
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002321Core and Builtins
2322-----------------
2323
Georg Brandl3e483f62008-07-16 22:57:41 +00002324- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2325 its methods now allow for items objects that can be converted to
2326 an integer using operator.index().
2327
Mark Dickinson64b7e502008-07-16 09:40:03 +00002328- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2329 produced a ValueError instead of giving the correct float.
2330
Eric Smitha5fa5a22008-07-16 00:11:49 +00002331- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2332 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2333
Mark Dickinson7103aa42008-07-15 19:08:33 +00002334- Issue #3008: the float type has a new instance method 'float.hex'
2335 and a new class method 'float.fromhex' to convert floating-point
2336 numbers to and from hexadecimal strings, respectively.
2337
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002338- Issue #2235: __hash__ is once again inherited by default. To allow
2339 collections.Hashable to remain meaningful in the presence of the
2340 default hash implementation (object.__hash__), it is now possible
2341 to explicit block inheritance of hash by setting __hash__=None at
2342 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2343 level.
2344
Nick Coghlanb028f502008-07-13 14:52:36 +00002345- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2346 the parent module cannot be found while performing an absolute import.
2347 This means that an incorrectly defined __package__ attribute will
2348 now only prevent relative imports in that module rather than causing
2349 all imports from that module to fail.
2350
Nick Coghlan14ff9942008-07-08 14:21:42 +00002351- Issue #2517: Allow unicode messages in Exceptions again by correctly
2352 bypassing the instance dictionary when looking up __unicode__ on
2353 new-style classes.
2354
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002355- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2356 set to a custom object whose write() method happens to install
2357 another file in sys.stdout.
2358
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002359- Issue #3088: Corrected a race condition in classes derived from
2360 threading.local: the first member set by a thread could be saved in
2361 another thread's dictionary.
2362
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002363- Issue #3004: Minor change to slice.indices(): the start and stop
2364 arguments are now treated identically, making the behaviour easier
2365 to describe and understand. For example, slice(None, -10,
2366 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2367 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2368 10, -1).
2369
Georg Brandl278fc502008-07-19 12:46:12 +00002370- Issue #3219: Calling a function with repeated keyword arguments,
2371 f(a=2, a=23), would not cause a syntax error. This was a regression
2372 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002373
Georg Brandl278fc502008-07-19 12:46:12 +00002374- Issue #2862: Make int and float freelist management consistent with
2375 other freelists. Changes their CompactFreeList apis into
2376 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002377

2379-------
2380
Thomas Heller57adf222008-08-14 19:10:48 +00002381- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2382 api functions without holding the GIL, which could lead to a fatal
2383 error when they failed.
2384
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002385- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002393- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2394 ForkingPickler.register() to resolve conflict with ctypes.
2395
Vinay Sajip51e65192008-07-18 09:01:10 +00002396- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002397
Thomas Heller880f5292008-07-15 19:39:38 +00002398- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2399 a valid dlerror() message.
2400
Thomas Heller2bad6572008-07-15 17:19:50 +00002401- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2402 incomplete structure was created.
2403
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002404- Issue #3339: dummy_thread.acquire() should not return None.

2407
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002408- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002409
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002410- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2411 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002412 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002413 content-length. The problem had been corrected in the 2.4 branch, but never
2414 merged into trunk.
2415
Georg Brandle78fbcc2008-07-05 10:13:36 +00002416- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002424 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002425
Vinay Sajip51e65192008-07-18 09:01:10 +00002426- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002427 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002428
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002429- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2430 handling is now the same as that of other special attributes like __name__).
2431
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002432- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2433 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002822 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002823
2824 This is controlled by the configure argument ``--with-universal-archs``:
2825
2826 - ``--with-universal-archs=all``: install 4-way universal
2827
2828 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2829
2830 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2831
2832 This option should be used in combination with ``--enable-universalsdk=``.
2833
2834 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 +00002884- Issue #1631171: Re-implement the 'warnings' module in C (the
2885 original Python code has been kept as backup). This will allow for
2886 using the 'warning's machinery in such places as the parser where
2887 use of pure Python code is not possible. Both the ``showarning()``
2888 and ``formatwarning()`` gain an optional 'line' argument which is
2889 not called by default for backwards-compatibility reasons. Setting
2890 ``warnings.showwarning()`` to an implementation that lacks support
2891 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Issue #2550: The approach used by client/server code for obtaining
2955 ports to listen on in network-oriented tests has been refined in an
2956 effort to facilitate running multiple instances of the entire
2957 regression test suite in parallel without issue.
2958 test_support.bind_port() has been fixed such that it will always
2959 return a unique port -- which wasn't always the case with the
2960 previous implementation, especially if socket options had been set
2961 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2962 new implementation of bind_port() will actually raise an exception
2963 if it is passed an AF_INET/SOCK_STREAM socket with either the
2964 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2965 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2966 the socket it's been passed. This currently only applies to
2967 Windows. This option prevents any other sockets from binding to the
2968 host/port we've bound to, thus removing the possibility of the
2969 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2970 when a second SOCK_STREAM socket binds and accepts to a host/port
2971 that's already been bound by another socket. The optional preferred
2972 port parameter to bind_port() has been removed. Under no
2973 circumstances should tests be hard coding ports!
2974
2975 test_support.find_unused_port() has also been introduced, which will
2976 pass a temporary socket object to bind_port() in order to obtain an
2977 unused port. The temporary socket object is then closed and
2978 deleted, and the port is returned. This method should only be used
2979 for obtaining an unused port in order to pass to an external program
2980 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2981 a parameter to a server-oriented class that doesn't give you direct
2982 access to the underlying socket used.
2983
2984 Finally, test_support.HOST has been introduced, which should be used
2985 for the host argument of any relevant socket calls (i.e. bind and
2986 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002987
2988 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2991 test_asynchat and test_socket_ssl.
2992
Georg Brandl3ee81df2008-05-17 18:14:43 +00002993 It is now possible for multiple instances of the regression test
2994 suite to run in parallel without issue.

3261-----------------
3262
Fred Drakea8ee94b2008-03-01 02:45:07 +00003263- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003264 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003265
Georg Brandlad61bc82008-02-23 15:11:18 +00003266- Issue #2067: file.__exit__() now calls subclasses' close() method.
3267
3268- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003269
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003270- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003271 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003272
Eric Smitha73fbe72008-02-23 03:09:44 +00003273- Added the future_builtins module, which contains hex() and oct().
3274 These are the PEP 3127 version of these functions, designed to be
3275 compatible with the hex() and oct() builtins from Python 3.0. They
3276 differ slightly in their output formats from the existing, unchanged
3277 Python 2.6 builtins. The expected usage of the future_builtins
3278 module is:
3279 from future_builtins import hex, oct
3280
Eric Smith7ef40bf2008-02-20 23:34:22 +00003281- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3282 exponents for exponents with absolute value < 100. Follows C99
3283 standard. This is a change on Windows, which would use 3 digits.
3284 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3285 so that any alterations it does to the resulting string will be
3286 available in stringlib/formatter.h (for float.__format__).
3287
Eric Smith5a3c1352008-02-19 13:21:56 +00003288- Implemented PEP 3101, Advanced String Formatting. This adds a new
3289 builtin format(); a format() method for str and unicode; a
3290 __format__() method to object, str, unicode, int, long, float, and
3291 datetime; the class string.Formatter; and the C API
3292 PyObject_Format().
3293
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294- Fixed several potential crashes, all caused by specially crafted
3295 __del__ methods exploiting objects in temporarily inconsistent
3296 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003297
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003298- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299 prevent a possible crash: an Abstract Base Class would try to access
3300 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Fixed repr() and str() of complex numbers with infinity or nan as
3303 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Clear all free lists during a gc.collect() of the highest generation
3306 in order to allow pymalloc to free more arenas. Python may give back
3307 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Issue #2045: Fix an infinite recursion triggered when printing a
3310 subclass of collections.defaultdict, if its default_factory is set
3311 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003312
Christian Heimesf75dbef2008-02-08 00:11:31 +00003313- Fixed a minor memory leak in dictobject.c. The content of the free
3314 list was not freed on interpreter shutdown.
3315
Georg Brandl5a7eca12010-03-21 19:29:04 +00003316- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003318
Georg Brandl3ee81df2008-05-17 18:14:43 +00003319- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3320 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003321 to compact the internal free lists of pre-allocted ints and floats.
3322
Georg Brandl3ee81df2008-05-17 18:14:43 +00003323- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3324 calls. Python expected the return type int but the fork familie
3325 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3328 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3331 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3334 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003335
Georg Brandl3ee81df2008-05-17 18:14:43 +00003336- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3337 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003338
Georg Brandl3ee81df2008-05-17 18:14:43 +00003339- Patch #1473257: generator objects gain a gi_code attribute. This is
3340 the same object as the func_code attribute of the function that
3341 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003342
Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1920: "while 0" statements were completely removed by the
3344 compiler, even in the presence of an "else" clause, which is
3345 supposed to be run when the condition is false. Now the compiler
3346 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003347
Guido van Rossumeead05f2008-01-24 18:21:02 +00003348- A few crashers fixed: weakref_in_del.py (issue #1377858);
3349 loosing_dict_ref.py (issue #1303614, test67.py);
3350 borrowed_ref_[34].py (not in tracker).
3351
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003352- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003353 suppressed while an extension is loaded by calling SetErrorMode in
3354 dynload_win.c. The error is still reported properly.
3355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003357 several extension methods and modules do not work without unicode
3358 support.
3359
Georg Brandl26543b12008-01-21 18:36:51 +00003360- Issue #1882: when compiling code from a string, encoding cookies in the
3361 second line of code were not always recognized correctly.
3362
Georg Brandl14404b62008-01-19 19:27:05 +00003363- Issue #1679: "0x" was taken as a valid integer literal.
3364
Georg Brandl6caad7d2008-01-26 14:19:22 +00003365- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003366 added.
3367
Christian Heimesc94e2b52008-01-14 04:13:37 +00003368- sys.float_info / PyFloat_GetInfo: The floating point information
3369 object was converted from a dict to a specialized structseq object.
3370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Patch #1816: Added sys.flags structseq. It exposes the status of
3372 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003373
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Objects/structseq.c: Implemented new structseq representation. The
3375 patch makes structseqs (e.g. the return value of os.stat) more
3376 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003377
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Patch #1700288: added a type attribute cache that caches method
3379 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003380
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003381- Bug #1776: __import__() no longer accepts filenames on any platform.
3382 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003383
Georg Brandlaed6c662008-01-07 17:25:53 +00003384- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3387 envvar and sys.dont_write_bytecode attribute. All these can be set
3388 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Improve some exception messages when Windows fails to load an
3391 extension module. Now we get for example '%1 is not a valid Win32
3392 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003393
Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3397 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003398
Christian Heimes0a8143f2007-12-18 23:22:54 +00003399- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400 and INF. float("nan"), float("inf") and float("-inf") now work on
3401 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003402
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403- Compiler now generates simpler and faster code for dictionary
3404 literals. The oparg for BUILD_MAP now indicates an estimated
3405 dictionary size. There is a new opcode, STORE_MAP, for adding
3406 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Issue #1620: New property decorator syntax was modifying the
3411 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Issue #1538: Avoid copying string in split/rsplit if the split char
3414 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003415
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003416- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003417 SystemError.
3418
Nick Coghlanef01d822007-12-03 12:55:17 +00003419- PEP 366: Allow explicit relative imports when executing modules
3420 inside packages with the -m switch via a new module level
3421 __package__ attribute.
3422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Issue #1402: Fix a crash on exit, when another thread is still
3424 running, and if the deallocation of its frames somehow calls the
3425 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003426

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003430 attribute of an empty cell object.
3431
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432- Issue #1460: The utf-7 incremental decoder did not accept truncated
3433 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Patch #1739468: Directories and zipfiles containing a __main__.py
3436 file can now be directly executed by passing their name to the
3437 interpreter. The directory/zipfile is automatically inserted as the
3438 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Issue #1265: Fix a problem with sys.settrace, if the tracing
3441 function uses a generator expression when at the same time the
3442 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003443
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003444- sets and frozensets now have an isdisjoint() method.
3445
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003446- optimize the performance of builtin.sum().
3447
Neal Norwitz44f326e2007-10-05 05:29:17 +00003448- Fix warnings found by the new version of the Coverity checker.
3449
Georg Brandl5a7eca12010-03-21 19:29:04 +00003450- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3452 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003453
Georg Brandl3ee81df2008-05-17 18:14:43 +00003454- Issue #1686386: Tuple's tp_repr did not take into account the
3455 possibility of having a self-referential tuple, which is possible
3456 from C code. Nor did object's tp_str consider that a type's tp_str
3457 could do something that could lead to an inifinite recursion.
3458 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3459 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Issue #1164: It was possible to trigger deadlock when using the
3462 'print' statement to write to a file since the GIL was not released
3463 as needed. Now PyObject_Print() does the right thing along with
3464 various tp_print implementations of the built-in types and those in
3465 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003466
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Issue #1147: Exceptions were directly allowing string exceptions in
3468 their throw() method even though string exceptions no longer
3469 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003470

Brett Cannon1e534b52007-09-07 04:18:30 +00003474- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475 PyObject_Call() never calling back out to Python code to trigger
3476 recursion depth updates/checks. Required the creation of a static
3477 RuntimeError instance in case normalizing an exception put the
3478 recursion check value past its limit. Fixes crashers
3479 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003480

Neal Norwitz0ac60192007-05-27 04:08:54 +00003494- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495 __*__ attributes. (Some already existed, e.g., __doc__ and
3496 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003497
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003498- Add -3 option to the interpreter to warn about features that are
3499 deprecated and will be changed/removed in Python 3.0.
3500

3502 calls.
3503
Collin Winter62903052007-05-18 23:11:24 +00003504- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505 "except E as target:". This is to provide forwards compatibility
3506 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003507
Brett Cannon229cee22007-05-05 01:34:02 +00003508- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003511 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003513- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003514 setting a plain string, ie don't expand to single letter identifiers.
3515
Raymond Hettinger13936692007-04-11 18:40:58 +00003516- Request #1191699: Slices can now be pickled.

3526
Guido van Rossum143b5642007-03-23 04:58:42 +00003527- Bug #1683368: The object.__init__() and object.__new__() methods are
3528 now stricter in rejecting excess arguments. The only time when
3529 either allows excess arguments is when it is not overridden and the
3530 other one is. For backwards compatibility, when both are
3531 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003532 warning later). Also, type.__init__() insists on the same signature
3533 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3536 object to complex using its __complex__() method before falling back
3537 to the __float__() method. Therefore, the functions in the cmath
3538 module now can operate on objects that define a __complex__()
3539 method.

3556
Georg Brandl7b9c5552007-03-12 14:30:05 +00003557- Bug #1678647: write a newline after printing an exception in any
3558 case, even when converting the value to a string failed.
3559
Georg Brandl871f1bc2007-03-12 13:17:36 +00003560- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561 its argument, if it exists. If not, it will work like before. This
3562 allows customizing the output of dir() in the presence of a
3563 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003564
Collin Winter276887b2007-03-12 16:11:39 +00003565- Patch #922167: Python no longer segfaults when faced with infinitely
3566 self-recursive reload() calls (as reported by bug #742342).

3572 parthensized forms. This means complex(repr(x)) now works instead of
3573 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003574
Georg Brandlaa2321b2007-03-07 00:40:28 +00003575- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576 makes the filenames the warning module prints much more sensible
3577 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003578

Georg Brandl0fca97a2007-03-05 22:28:08 +00003590- Patch #1674228: when assigning a slice (old-style), check for the
3591 sq_ass_slice instead of the sq_slice slot.
3592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- When printing an unraisable error, don't print exceptions. before

3595 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004128 AttributeError instead of an IOError when the server's response

4220 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4506 with RFC 3207 and forgets any knowledge obtained from the server not
4507 obtained from the TLS negotiation itself. Patch contributed by Bill
4508 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004511 that the SMTP.starttls() caller no longer needs to call ehlo()
4512 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513 does not claim to support starttls. Adds the
4514 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4595 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4596 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004613 time so that opening a database previously created with the DB_DUP
4614 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4615 opens. Specifically: dictionary assignment to a DB object will
4616 replace all values for a given key when the database allows
4617 duplicate values. DB users should use DB.put(k, v) when they want
4618 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004619

4625 characters with ASCII value less than 32. Also, it correctly quotes
4626 dots only if they occur on a single line, as opposed to the previous
4627 behavior of quoting dots if they are the second character of any
4628 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004958- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4959 to ``PyTuple_SetItem``, it can be used to populate a brand new
4960 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004964- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4965 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4966 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004967
4968- Patch #1720595: add T_BOOL to the range of structmember types.

4972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4974 of w# format code incorrectly truncated the length to an int, even
4975 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4976 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4979 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004981- PEP 3123: Provide forward compatibility with Python 3.0, while
4982 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4983 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4986 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004987
4988- Patch #1733960: Allow T_LONGLONG to accept ints.
4989
4990- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4991
Christian Heimes000a0742008-01-03 22:16:32 +00004992- Added a new API function ``PyImport_ImportModuleNoBlock``.
4993
Georg Brandl6caad7d2008-01-26 14:19:22 +00004994- Bug #1637022: Prefix AST symbols with _Py_.
4995
4996- Fix some leftovers from the conversion from int to Py_ssize_t
4997 (relevant to strings and sequences of more than 2**31 items).
4998
4999- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5000 outside of pystate.c and should not be necessary.
5001
Georg Brandl3ee81df2008-05-17 18:14:43 +00005002- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5003 absolute imports. In earlier versions they might have used relative
5004 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005005
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5007 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005008
Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005016- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5017 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5018 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5019 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005020

Brett Cannon791d56f2007-05-31 19:40:42 +00005032- buildtools now raises a DeprecationWarning.
5033
Georg Brandl3ee81df2008-05-17 18:14:43 +00005034- Removed the macfs module. It had been deprecated since Python 2.5.
5035 This lead to the deprecation of macostools.touched() as it relied
5036 solely on macfs and was a no-op under OS X.
