1529
Jesse Nollere6bab482009-03-30 16:11:16 +00001530- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks

1532 check it is possible to segfault the interpreter.

1571 do an explicit seek to the end of file (so that e.g. tell() returns the

1573 traditional 2.x file object.

Georg Brandl21896072010-08-01 22:31:28 +00001585- Issue #4790: The nsmallest() and nlargest() functions in the heapq module
Raymond Hettingerd263bd82008-12-31 04:18:44 +00001586 did unnecessary work in the common case where no key function was specified.

1604 zipimport (or any other conformant PEP 302 loader). Original patch by
1605 Alexander Belopolsky.
1606
1607- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1608 302 conformant loader) will now work correctly in most cases (they

1769What's New in Python 2.6.1
1770==========================
1771
1772*Release date: 04-Dec-2008*
1773
1774Core and Builtins
1775-----------------
1776
1777- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1778 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1779 instead of throwing a MemoryError.
1780
1781- Issue #4367: Python would segfault during compiling when the unicodedata
1782 module couldn't be imported and \N escapes were present.
1783
1784- Issue #4348: Some bytearray methods returned that didn't cause any change to
1785 the bytearray, returned the same bytearray instead of a copy.
1786
1787- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1788
1789- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1790
1791- Issue #4048: The parser module now correctly validates relative imports.
1792
1793- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1794 exec statement.
1795
1796- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1797 method does not return iterators for the 4th and 5th items.
1798
1799- Issue #4209: Enabling unicode_literals and the print_function in the same
1800 __future__ import didn't work.
1801
1802- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1803 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1804 really executed because I cannot move to such directory on win2k)
1805
1806- Issue #4069: When set.remove(element) is used with a set element, the element
1807 is temporarily replaced with an equivalent frozenset. But the eventual
1808 KeyError would always report the empty frozenset([]) as the missing key. Now
1809 it correctly refers to the initial element.
1810
1811- Fixed C99 style comments in several files. Python is now C89 compatible
1812 again.

1960
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001961- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1962 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1963 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1964 ``printf`` function, whereas PyString_FromFormat has an independent
1965 implementation and uses "%zd" on all platforms for size_t values.
1966 This makes a difference on win64, where ``printf`` needs "%Id" to display
1967 64bit values.

1973 object; previously an int would be returned for small values. the __long__
1974 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001984 was correctly parsed but parsing of subsequent arguments failed.
1985
Vinay Sajip35e3b032008-09-01 14:33:59 +00001986- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001987 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1988 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1989 when given a tuple of classes as second argument, were looking up
1990 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1991 type object.
1992

2133-----------------
2134
Guido van Rossumf8402962008-08-20 15:01:50 +00002135- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2136 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2137 extensions do not automatically benefit from the class attribute
2138 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2139 to their tp_flags field if they care. This is a backwards
2140 compatibility feature; in 3.0, all types will use the cache by
2141 default.

2160 (64bit Unix, for example), unichr() would truncate its argument and return
2161 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2162
Neal Norwitze7d8be82008-07-31 17:17:14 +00002163- Apply security patches from Apple.
2164
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002165- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2166 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2167
Antoine Pitrou92f82162008-07-25 22:22:08 +00002168- Issue #1819: function calls with several named parameters are now on
2169 average 35% faster (as measured by pybench).
2170
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002171- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2172 the python debugger steps into a class statement: the free variables (local
2173 variables defined in an outer scope) would be deleted from the outer scope.
2174
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002175- Issue #2620: Overflow checking when allocating or reallocating memory
2176 was not always being done properly in some python types and extension
2177 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2178 all been updated to perform better checks and places in the code that
2179 would previously leak memory on the error path when such an allocation
2180 failed have been fixed.

2186
Benjamin Petersone977ad42008-08-20 01:42:01 +00002187- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2188 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2189
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002190- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2191 version reported by these tools does not necessarily follow the python
2192 version numbering scheme, so the module is less strict when parsing it.
2193
Nick Coghlanf70385a2008-08-18 12:42:46 +00002194- Issue #2235: Added Py3k warnings for types which will become unhashable
2195 under the stricter __hash__ inheritance rules in 3.0. Several types
2196 which did not meet the rules for hash invariants and were already
2197 unhashable in 3.0 have now been explicitly flagged as unhashable in
2198 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2199 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2200
Brett Cannon88f801d2008-08-18 00:46:22 +00002201- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2202 imported into the module but exposed as part of the module's API.
2203

2227 regular expression.
2228
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002229- Issue #3476: binary buffered reading through the new "io" library is now
2230 thread-safe.
2231
Brett Cannonbf3157b2008-08-14 05:00:03 +00002232- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2233 since mimetools itself is deprecated. Because modules are cached, all
2234 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2235
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002236- Issue #3134: shutil referenced undefined WindowsError symbol.

2245 a MemoryError rather than silently stop the iteration.
2246
Guido van Rossum59ce9012008-08-09 14:55:34 +00002247- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2248 to _sre.compile() will now be rejected. This should not affect anybody
2249 since the re.compile() function never generates invalid re-bytecode.
2250
Skip Montanaroa032bf42008-08-08 22:52:51 +00002251- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2252 upon first access it can be automatically initialized from the csv file if
2253 it wasn't initialized during instantiation.
2254
Brett Cannon3aa2a492008-08-06 22:28:09 +00002255- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2256 the reload() built-in has been removed.
2257
Brett Cannon7e30b672008-08-04 21:52:25 +00002258- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002259 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2267 raised an AttributeError.
2268
Benjamin Peterson01a24322008-07-28 23:35:27 +00002269- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002270 asking for a specific length. This problem only affected files opened
2271 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002296- Issue #3394: zipfile.writestr sets external attributes when passed a
2297 file name rather than a ZipInfo instance, so files are extracted with
2298 mode 0600 rather than 000 under Unix.
2299
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002300- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2301 argument in python 2.5, this broke code that subclassed Popen to include its
2302 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2313 interaction with the tp_hash slot (added in 2.6b2) are now documented
2314
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002315- Issue #643841: The language reference now provides more detailed
2316 coverage of the lookup process for special methods. The disclaimers
2317 regarding lack of coverage of new-style classes have also been
2318 removed, since the coverage is now fairly reasonable.

2322================================
2323
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002324*Release date: 17-Jul-2008*
2325
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002326Core and Builtins
2327-----------------
2328
Georg Brandl3e483f62008-07-16 22:57:41 +00002329- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2330 its methods now allow for items objects that can be converted to
2331 an integer using operator.index().
2332
Mark Dickinson64b7e502008-07-16 09:40:03 +00002333- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2334 produced a ValueError instead of giving the correct float.
2335
Eric Smitha5fa5a22008-07-16 00:11:49 +00002336- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2337 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2338
Mark Dickinson7103aa42008-07-15 19:08:33 +00002339- Issue #3008: the float type has a new instance method 'float.hex'
2340 and a new class method 'float.fromhex' to convert floating-point
2341 numbers to and from hexadecimal strings, respectively.
2342
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002343- Issue #2235: __hash__ is once again inherited by default. To allow
2344 collections.Hashable to remain meaningful in the presence of the
2345 default hash implementation (object.__hash__), it is now possible
2346 to explicit block inheritance of hash by setting __hash__=None at
2347 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2348 level.
2349
Nick Coghlanb028f502008-07-13 14:52:36 +00002350- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2351 the parent module cannot be found while performing an absolute import.
2352 This means that an incorrectly defined __package__ attribute will
2353 now only prevent relative imports in that module rather than causing
2354 all imports from that module to fail.
2355
Nick Coghlan14ff9942008-07-08 14:21:42 +00002356- Issue #2517: Allow unicode messages in Exceptions again by correctly
2357 bypassing the instance dictionary when looking up __unicode__ on
2358 new-style classes.
2359
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002360- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2361 set to a custom object whose write() method happens to install
2362 another file in sys.stdout.
2363
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002364- Issue #3088: Corrected a race condition in classes derived from
2365 threading.local: the first member set by a thread could be saved in
2366 another thread's dictionary.
2367
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002368- Issue #3004: Minor change to slice.indices(): the start and stop
2369 arguments are now treated identically, making the behaviour easier
2370 to describe and understand. For example, slice(None, -10,
2371 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2372 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2373 10, -1).
2374
Georg Brandl278fc502008-07-19 12:46:12 +00002375- Issue #3219: Calling a function with repeated keyword arguments,
2376 f(a=2, a=23), would not cause a syntax error. This was a regression
2377 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002378
Georg Brandl278fc502008-07-19 12:46:12 +00002379- Issue #2862: Make int and float freelist management consistent with
2380 other freelists. Changes their CompactFreeList apis into
2381 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002382

2384-------
2385
Thomas Heller57adf222008-08-14 19:10:48 +00002386- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2387 api functions without holding the GIL, which could lead to a fatal
2388 error when they failed.
2389
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002390- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002398- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2399 ForkingPickler.register() to resolve conflict with ctypes.
2400
Vinay Sajip51e65192008-07-18 09:01:10 +00002401- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002402
Thomas Heller880f5292008-07-15 19:39:38 +00002403- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2404 a valid dlerror() message.
2405
Thomas Heller2bad6572008-07-15 17:19:50 +00002406- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2407 incomplete structure was created.
2408
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002409- Issue #3339: dummy_thread.acquire() should not return None.
2410
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002411- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2412
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002413- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002414
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002415- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2416 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002417 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002418 content-length. The problem had been corrected in the 2.4 branch, but never
2419 merged into trunk.
2420
Georg Brandle78fbcc2008-07-05 10:13:36 +00002421- Issue #2663: add filtering capability to shutil.copytree().

2425- Issue #1526: Allow more than 64k files to be added to Zip64 file.
2426
2427- Issue #1746: Correct handling of zipfile archive comments (previously
2428 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002429 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002430
Vinay Sajip51e65192008-07-18 09:01:10 +00002431- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002432 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002433
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002434- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2435 handling is now the same as that of other special attributes like __name__).
2436
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002437- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002827 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002828
2829 This is controlled by the configure argument ``--with-universal-archs``:
2830
2831 - ``--with-universal-archs=all``: install 4-way universal
2832
2833 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2834
2835 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2836
2837 This option should be used in combination with ``--enable-universalsdk=``.
2838
2839 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 +00002889- Issue #1631171: Re-implement the 'warnings' module in C (the
2890 original Python code has been kept as backup). This will allow for
2891 using the 'warning's machinery in such places as the parser where
2892 use of pure Python code is not possible. Both the ``showarning()``
2893 and ``formatwarning()`` gain an optional 'line' argument which is
2894 not called by default for backwards-compatibility reasons. Setting
2895 ``warnings.showwarning()`` to an implementation that lacks support
2896 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Issue #2550: The approach used by client/server code for obtaining
2960 ports to listen on in network-oriented tests has been refined in an
2961 effort to facilitate running multiple instances of the entire
2962 regression test suite in parallel without issue.
2963 test_support.bind_port() has been fixed such that it will always
2964 return a unique port -- which wasn't always the case with the
2965 previous implementation, especially if socket options had been set
2966 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2967 new implementation of bind_port() will actually raise an exception
2968 if it is passed an AF_INET/SOCK_STREAM socket with either the
2969 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2970 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2971 the socket it's been passed. This currently only applies to
2972 Windows. This option prevents any other sockets from binding to the
2973 host/port we've bound to, thus removing the possibility of the
2974 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2975 when a second SOCK_STREAM socket binds and accepts to a host/port
2976 that's already been bound by another socket. The optional preferred
2977 port parameter to bind_port() has been removed. Under no
2978 circumstances should tests be hard coding ports!
2979
2980 test_support.find_unused_port() has also been introduced, which will
2981 pass a temporary socket object to bind_port() in order to obtain an
2982 unused port. The temporary socket object is then closed and
2983 deleted, and the port is returned. This method should only be used
2984 for obtaining an unused port in order to pass to an external program
2985 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2986 a parameter to a server-oriented class that doesn't give you direct
2987 access to the underlying socket used.
2988
2989 Finally, test_support.HOST has been introduced, which should be used
2990 for the host argument of any relevant socket calls (i.e. bind and
2991 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002992
2993 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002995 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2996 test_asynchat and test_socket_ssl.
2997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998 It is now possible for multiple instances of the regression test
2999 suite to run in parallel without issue.

3266-----------------
3267
Fred Drakea8ee94b2008-03-01 02:45:07 +00003268- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003269 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003270
Georg Brandlad61bc82008-02-23 15:11:18 +00003271- Issue #2067: file.__exit__() now calls subclasses' close() method.
3272
3273- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003274
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003275- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003276 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003277
Eric Smitha73fbe72008-02-23 03:09:44 +00003278- Added the future_builtins module, which contains hex() and oct().
3279 These are the PEP 3127 version of these functions, designed to be
3280 compatible with the hex() and oct() builtins from Python 3.0. They
3281 differ slightly in their output formats from the existing, unchanged
3282 Python 2.6 builtins. The expected usage of the future_builtins
3283 module is:
3284 from future_builtins import hex, oct
3285
Eric Smith7ef40bf2008-02-20 23:34:22 +00003286- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3287 exponents for exponents with absolute value < 100. Follows C99
3288 standard. This is a change on Windows, which would use 3 digits.
3289 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3290 so that any alterations it does to the resulting string will be
3291 available in stringlib/formatter.h (for float.__format__).
3292
Eric Smith5a3c1352008-02-19 13:21:56 +00003293- Implemented PEP 3101, Advanced String Formatting. This adds a new
3294 builtin format(); a format() method for str and unicode; a
3295 __format__() method to object, str, unicode, int, long, float, and
3296 datetime; the class string.Formatter; and the C API
3297 PyObject_Format().
3298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Fixed several potential crashes, all caused by specially crafted
3300 __del__ methods exploiting objects in temporarily inconsistent
3301 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003302
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003303- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304 prevent a possible crash: an Abstract Base Class would try to access
3305 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Fixed repr() and str() of complex numbers with infinity or nan as
3308 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003309
Georg Brandl3ee81df2008-05-17 18:14:43 +00003310- Clear all free lists during a gc.collect() of the highest generation
3311 in order to allow pymalloc to free more arenas. Python may give back
3312 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Issue #2045: Fix an infinite recursion triggered when printing a
3315 subclass of collections.defaultdict, if its default_factory is set
3316 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003317
Christian Heimesf75dbef2008-02-08 00:11:31 +00003318- Fixed a minor memory leak in dictobject.c. The content of the free
3319 list was not freed on interpreter shutdown.
3320
Georg Brandl5a7eca12010-03-21 19:29:04 +00003321- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3325 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003326 to compact the internal free lists of pre-allocted ints and floats.
3327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3329 calls. Python expected the return type int but the fork familie
3330 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003331
Georg Brandl3ee81df2008-05-17 18:14:43 +00003332- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3333 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3336 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3339 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3342 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Patch #1473257: generator objects gain a gi_code attribute. This is
3345 the same object as the func_code attribute of the function that
3346 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Issue #1920: "while 0" statements were completely removed by the
3349 compiler, even in the presence of an "else" clause, which is
3350 supposed to be run when the condition is false. Now the compiler
3351 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003352
Guido van Rossumeead05f2008-01-24 18:21:02 +00003353- A few crashers fixed: weakref_in_del.py (issue #1377858);
3354 loosing_dict_ref.py (issue #1303614, test67.py);
3355 borrowed_ref_[34].py (not in tracker).
3356
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003357- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003358 suppressed while an extension is loaded by calling SetErrorMode in
3359 dynload_win.c. The error is still reported properly.
3360
Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003362 several extension methods and modules do not work without unicode
3363 support.
3364
Georg Brandl26543b12008-01-21 18:36:51 +00003365- Issue #1882: when compiling code from a string, encoding cookies in the
3366 second line of code were not always recognized correctly.
3367
Georg Brandl14404b62008-01-19 19:27:05 +00003368- Issue #1679: "0x" was taken as a valid integer literal.
3369
Georg Brandl6caad7d2008-01-26 14:19:22 +00003370- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003371 added.
3372
Christian Heimesc94e2b52008-01-14 04:13:37 +00003373- sys.float_info / PyFloat_GetInfo: The floating point information
3374 object was converted from a dict to a specialized structseq object.
3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Patch #1816: Added sys.flags structseq. It exposes the status of
3377 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Objects/structseq.c: Implemented new structseq representation. The
3380 patch makes structseqs (e.g. the return value of os.stat) more
3381 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Patch #1700288: added a type attribute cache that caches method
3384 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003385
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003386- Bug #1776: __import__() no longer accepts filenames on any platform.
3387 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003388
Georg Brandlaed6c662008-01-07 17:25:53 +00003389- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3392 envvar and sys.dont_write_bytecode attribute. All these can be set
3393 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Improve some exception messages when Windows fails to load an
3396 extension module. Now we get for example '%1 is not a valid Win32
3397 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003401- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3402 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003403
Christian Heimes0a8143f2007-12-18 23:22:54 +00003404- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003405 and INF. float("nan"), float("inf") and float("-inf") now work on
3406 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Compiler now generates simpler and faster code for dictionary
3409 literals. The oparg for BUILD_MAP now indicates an estimated
3410 dictionary size. There is a new opcode, STORE_MAP, for adding
3411 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Issue #1638: %zd configure test fails on Linux.

3426 __package__ attribute.
3427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Issue #1402: Fix a crash on exit, when another thread is still
3429 running, and if the deallocation of its frames somehow calls the
3430 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003431

3441 file can now be directly executed by passing their name to the
3442 interpreter. The directory/zipfile is automatically inserted as the
3443 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Issue #1265: Fix a problem with sys.settrace, if the tracing
3446 function uses a generator expression when at the same time the
3447 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003448
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003449- sets and frozensets now have an isdisjoint() method.
3450
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003451- optimize the performance of builtin.sum().
3452
Neal Norwitz44f326e2007-10-05 05:29:17 +00003453- Fix warnings found by the new version of the Coverity checker.
3454
Georg Brandl5a7eca12010-03-21 19:29:04 +00003455- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3457 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Issue #1686386: Tuple's tp_repr did not take into account the
3460 possibility of having a self-referential tuple, which is possible
3461 from C code. Nor did object's tp_str consider that a type's tp_str
3462 could do something that could lead to an inifinite recursion.
3463 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3464 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Issue #1164: It was possible to trigger deadlock when using the
3467 'print' statement to write to a file since the GIL was not released
3468 as needed. Now PyObject_Print() does the right thing along with
3469 various tp_print implementations of the built-in types and those in
3470 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003471
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Issue #1147: Exceptions were directly allowing string exceptions in
3473 their throw() method even though string exceptions no longer
3474 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003475

Brett Cannon1e534b52007-09-07 04:18:30 +00003479- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480 PyObject_Call() never calling back out to Python code to trigger
3481 recursion depth updates/checks. Required the creation of a static
3482 RuntimeError instance in case normalizing an exception put the
3483 recursion check value past its limit. Fixes crashers
3484 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003499- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500 __*__ attributes. (Some already existed, e.g., __doc__ and
3501 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00003510 "except E as target:". This is to provide forwards compatibility
3511 with Python 3.0.

3531
Guido van Rossum143b5642007-03-23 04:58:42 +00003532- Bug #1683368: The object.__init__() and object.__new__() methods are
3533 now stricter in rejecting excess arguments. The only time when
3534 either allows excess arguments is when it is not overridden and the
3535 other one is. For backwards compatibility, when both are
3536 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003537 warning later). Also, type.__init__() insists on the same signature
3538 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3541 object to complex using its __complex__() method before falling back
3542 to the __float__() method. Therefore, the functions in the cmath
3543 module now can operate on objects that define a __complex__()
3544 method.

3561
Georg Brandl7b9c5552007-03-12 14:30:05 +00003562- Bug #1678647: write a newline after printing an exception in any
3563 case, even when converting the value to a string failed.
3564
Georg Brandl871f1bc2007-03-12 13:17:36 +00003565- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003566 its argument, if it exists. If not, it will work like before. This
3567 allows customizing the output of dir() in the presence of a
3568 __getattr__().

3578 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003579
Georg Brandlaa2321b2007-03-07 00:40:28 +00003580- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003581 makes the filenames the warning module prints much more sensible
3582 when a PYTHONSTARTUP file is used.

3596 sq_ass_slice instead of the sq_slice slot.
3597
Georg Brandl3ee81df2008-05-17 18:14:43 +00003598- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- unittest now verifies more of its assumptions. In particular,
4225 TestCase and TestSuite subclasses (not instances) are no longer
4226 accepted in TestSuite.addTest(). This should cause no
4227 incompatibility since it never made sense with ordinary subclasses
4228 -- the failure just occurred later, with a more cumbersome
4229 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4511 with RFC 3207 and forgets any knowledge obtained from the server not
4512 obtained from the TLS negotiation itself. Patch contributed by Bill
4513 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004516 that the SMTP.starttls() caller no longer needs to call ehlo()
4517 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518 does not claim to support starttls. Adds the
4519 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4600 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4601 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004618 time so that opening a database previously created with the DB_DUP
4619 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4620 opens. Specifically: dictionary assignment to a DB object will
4621 replace all values for a given key when the database allows
4622 duplicate values. DB users should use DB.put(k, v) when they want
4623 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004624

4630 characters with ASCII value less than 32. Also, it correctly quotes
4631 dots only if they occur on a single line, as opposed to the previous
4632 behavior of quoting dots if they are the second character of any
4633 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004634

Georg Brandl3ee81df2008-05-17 18:14:43 +00004958- Unified naming convention for free lists and their limits. All free
4959 lists in Object/ are named ``free_list``, the counter ``numfree``
4960 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4961 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4964 to ``PyTuple_SetItem``, it can be used to populate a brand new
4965 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004966
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004967- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004968
Georg Brandl3ee81df2008-05-17 18:14:43 +00004969- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4970 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4971 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004972
4973- Patch #1720595: add T_BOOL to the range of structmember types.
4974
4975- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4976 ``PyFloat_GetInfo()`` to the float API.
4977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4979 of w# format code incorrectly truncated the length to an int, even
4980 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4981 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4984 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004985
Georg Brandl3ee81df2008-05-17 18:14:43 +00004986- PEP 3123: Provide forward compatibility with Python 3.0, while
4987 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4988 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004989
Georg Brandl3ee81df2008-05-17 18:14:43 +00004990- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4991 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004992
4993- Patch #1733960: Allow T_LONGLONG to accept ints.
4994
4995- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4996
Christian Heimes000a0742008-01-03 22:16:32 +00004997- Added a new API function ``PyImport_ImportModuleNoBlock``.
4998
Georg Brandl6caad7d2008-01-26 14:19:22 +00004999- Bug #1637022: Prefix AST symbols with _Py_.
5000
5001- Fix some leftovers from the conversion from int to Py_ssize_t
5002 (relevant to strings and sequences of more than 2**31 items).
5003
5004- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5005 outside of pystate.c and should not be necessary.
5006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5008 absolute imports. In earlier versions they might have used relative
5009 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005010
Georg Brandl3ee81df2008-05-17 18:14:43 +00005011- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5012 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005013
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5015 macro so it can be used as an expression.

5020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5022 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5023 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5024 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005025
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5027 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005037- buildtools now raises a DeprecationWarning.
5038
Georg Brandl3ee81df2008-05-17 18:14:43 +00005039- Removed the macfs module. It had been deprecated since Python 2.5.
5040 This lead to the deprecation of macostools.touched() as it relied
5041 solely on macfs and was a no-op under OS X.
