108 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

361 Decimal operation raises multiple signals and more than one of those
362 signals is trapped, the specification determines the order in which
363 the signals should be handled. In many cases this order wasn't
364 being followed, leading to the wrong Python exception being raised.

398 where the method could block indefinitely if called just before the
399 event loop started running. This also fixes the occasional freezes
400 witnessed in test_httpservers.
401
Antoine Pitrouc689d962010-04-24 20:13:37 +0000402- Issue #5103: SSL handshake would ignore the socket timeout and block

1748What's New in Python 2.6.1
1749==========================
1750
1751*Release date: 04-Dec-2008*
1752
1753Core and Builtins
1754-----------------
1755
1756- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1757 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1758 instead of throwing a MemoryError.
1759
1760- Issue #4367: Python would segfault during compiling when the unicodedata
1761 module couldn't be imported and \N escapes were present.
1762
1763- Issue #4348: Some bytearray methods returned that didn't cause any change to
1764 the bytearray, returned the same bytearray instead of a copy.
1765
1766- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1767
1768- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1769
1770- Issue #4048: The parser module now correctly validates relative imports.
1771
1772- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1773 exec statement.
1774
1775- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1776 method does not return iterators for the 4th and 5th items.
1777
1778- Issue #4209: Enabling unicode_literals and the print_function in the same
1779 __future__ import didn't work.
1780
1781- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1782 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1783 really executed because I cannot move to such directory on win2k)
1784
1785- Issue #4069: When set.remove(element) is used with a set element, the element
1786 is temporarily replaced with an equivalent frozenset. But the eventual
1787 KeyError would always report the empty frozenset([]) as the missing key. Now
1788 it correctly refers to the initial element.
1789
1790- Fixed C99 style comments in several files. Python is now C89 compatible
1791 again.

1937
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001938- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1939
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001940- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1941 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1942 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1943 ``printf`` function, whereas PyString_FromFormat has an independent
1944 implementation and uses "%zd" on all platforms for size_t values.
1945 This makes a difference on win64, where ``printf`` needs "%Id" to display
1946 64bit values.
1947
Benjamin Peterson97179b02008-09-09 20:55:01 +00001948- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1950
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001951- Issue #3777: long() applied to a float object now always return a long
1952 object; previously an int would be returned for small values. the __long__
1953 method is allowed to return either an int or a long, but the behaviour of
1954 float objects should not change to respect backward compatibility.
1955
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001956- Issue #3751: str.rpartition would perform a left-partition when called with
1957 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001962 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001963 was correctly parsed but parsing of subsequent arguments failed.
1964
Vinay Sajip35e3b032008-09-01 14:33:59 +00001965- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001966 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1967 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1968 when given a tuple of classes as second argument, were looking up
1969 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1970 type object.
1971
Neal Norwitz18aa3882008-08-24 05:04:52 +00001972- Fix crashes on memory allocation failure found with failmalloc.
1973
1974- Fix memory leaks found with valgrind and update suppressions file.
1975
1976- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1981 function 'stringlib_contains_obj'.

Brett Cannon1eaf0742008-09-02 01:25:16 +00002041 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2042 for catch_warnings() also led to an improvement in the raising of a

2112-----------------
2113
Guido van Rossumf8402962008-08-20 15:01:50 +00002114- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2115 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2116 extensions do not automatically benefit from the class attribute
2117 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2118 to their tp_flags field if they care. This is a backwards
2119 compatibility feature; in 3.0, all types will use the cache by
2120 default.
2121
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002122- Keyword arguments can now follow starred arguments. (``f(a, *args,
2123 keyword=23)`` is now valid syntax.)
2124
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002125- ctypes function pointers that are COM methods have a boolean True
2126 value again.
2127
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002128- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2129 by denying s# to parse objects that have a releasebuffer procedure,
2130 and introducing s*.
2131
Georg Brandl1e13ea92008-08-11 09:07:59 +00002132- Issue #3537: Fix an assertion failure when an empty but presized dict
2133 object was stored in the freelist.
2134
Mark Dickinsonb6467572008-08-04 21:30:09 +00002135- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2136 ValueError consistently across platforms.
2137
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002138- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2139 (64bit Unix, for example), unichr() would truncate its argument and return
2140 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2141
Neal Norwitze7d8be82008-07-31 17:17:14 +00002142- Apply security patches from Apple.
2143
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002144- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2145 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2146
Antoine Pitrou92f82162008-07-25 22:22:08 +00002147- Issue #1819: function calls with several named parameters are now on
2148 average 35% faster (as measured by pybench).
2149
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002150- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2151 the python debugger steps into a class statement: the free variables (local
2152 variables defined in an outer scope) would be deleted from the outer scope.
2153
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002154- Issue #2620: Overflow checking when allocating or reallocating memory
2155 was not always being done properly in some python types and extension
2156 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2157 all been updated to perform better checks and places in the code that
2158 would previously leak memory on the error path when such an allocation
2159 failed have been fixed.

2168
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002169- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2170 version reported by these tools does not necessarily follow the python
2171 version numbering scheme, so the module is less strict when parsing it.
2172
Nick Coghlanf70385a2008-08-18 12:42:46 +00002173- Issue #2235: Added Py3k warnings for types which will become unhashable
2174 under the stricter __hash__ inheritance rules in 3.0. Several types
2175 which did not meet the rules for hash invariants and were already
2176 unhashable in 3.0 have now been explicitly flagged as unhashable in
2177 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2178 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2179
Brett Cannon88f801d2008-08-18 00:46:22 +00002180- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2181 imported into the module but exposed as part of the module's API.
2182

2209 thread-safe.
2210
Brett Cannonbf3157b2008-08-14 05:00:03 +00002211- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2212 since mimetools itself is deprecated. Because modules are cached, all
2213 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2214

2227 to _sre.compile() will now be rejected. This should not affect anybody
2228 since the re.compile() function never generates invalid re-bytecode.
2229
Skip Montanaroa032bf42008-08-08 22:52:51 +00002230- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2232 it wasn't initialized during instantiation.
2233
Brett Cannon3aa2a492008-08-06 22:28:09 +00002234- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2235 the reload() built-in has been removed.
2236
Brett Cannon7e30b672008-08-04 21:52:25 +00002237- Changed code in the following modules/packages to remove warnings raised

2246 raised an AttributeError.
2247

Antoine Pitroude781a42008-08-09 12:43:23 +00002249 asking for a specific length. This problem only affected files opened
2250 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002251

2276 file name rather than a ZipInfo instance, so files are extracted with
2277 mode 0600 rather than 000 under Unix.
2278
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002279- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2293
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002294- Issue #643841: The language reference now provides more detailed
2295 coverage of the lookup process for special methods. The disclaimers
2296 regarding lack of coverage of new-style classes have also been
2297 removed, since the coverage is now fairly reasonable.

2301================================
2302
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002303*Release date: 17-Jul-2008*
2304
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002305Core and Builtins
2306-----------------
2307
Georg Brandl3e483f62008-07-16 22:57:41 +00002308- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2309 its methods now allow for items objects that can be converted to
2310 an integer using operator.index().
2311
Mark Dickinson64b7e502008-07-16 09:40:03 +00002312- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2313 produced a ValueError instead of giving the correct float.
2314
Eric Smitha5fa5a22008-07-16 00:11:49 +00002315- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2316 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2317
Mark Dickinson7103aa42008-07-15 19:08:33 +00002318- Issue #3008: the float type has a new instance method 'float.hex'
2319 and a new class method 'float.fromhex' to convert floating-point
2320 numbers to and from hexadecimal strings, respectively.
2321
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002322- Issue #2235: __hash__ is once again inherited by default. To allow
2323 collections.Hashable to remain meaningful in the presence of the
2324 default hash implementation (object.__hash__), it is now possible
2325 to explicit block inheritance of hash by setting __hash__=None at
2326 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2327 level.
2328
Nick Coghlanb028f502008-07-13 14:52:36 +00002329- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2330 the parent module cannot be found while performing an absolute import.
2331 This means that an incorrectly defined __package__ attribute will
2332 now only prevent relative imports in that module rather than causing
2333 all imports from that module to fail.
2334
Nick Coghlan14ff9942008-07-08 14:21:42 +00002335- Issue #2517: Allow unicode messages in Exceptions again by correctly
2336 bypassing the instance dictionary when looking up __unicode__ on
2337 new-style classes.
2338
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002339- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2340 set to a custom object whose write() method happens to install
2341 another file in sys.stdout.
2342
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002343- Issue #3088: Corrected a race condition in classes derived from
2344 threading.local: the first member set by a thread could be saved in
2345 another thread's dictionary.
2346
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002347- Issue #3004: Minor change to slice.indices(): the start and stop
2348 arguments are now treated identically, making the behaviour easier
2349 to describe and understand. For example, slice(None, -10,
2350 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2351 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2352 10, -1).
2353
Georg Brandl278fc502008-07-19 12:46:12 +00002354- Issue #3219: Calling a function with repeated keyword arguments,
2355 f(a=2, a=23), would not cause a syntax error. This was a regression
2356 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002357
Georg Brandl278fc502008-07-19 12:46:12 +00002358- Issue #2862: Make int and float freelist management consistent with
2359 other freelists. Changes their CompactFreeList apis into
2360 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002365- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2366 api functions without holding the GIL, which could lead to a fatal
2367 error when they failed.
2368
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002369- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00002380- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002394- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2395 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002396 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002397 content-length. The problem had been corrected in the 2.4 branch, but never
2398 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002413- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2415
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002416- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2805 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002806 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002807
2808 This is controlled by the configure argument ``--with-universal-archs``:
2809
2810 - ``--with-universal-archs=all``: install 4-way universal
2811
2812 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2813
2814 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2815
2816 This option should be used in combination with ``--enable-universalsdk=``.
2817
2818 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 +00002868- Issue #1631171: Re-implement the 'warnings' module in C (the
2869 original Python code has been kept as backup). This will allow for
2870 using the 'warning's machinery in such places as the parser where
2871 use of pure Python code is not possible. Both the ``showarning()``
2872 and ``formatwarning()`` gain an optional 'line' argument which is
2873 not called by default for backwards-compatibility reasons. Setting
2874 ``warnings.showwarning()`` to an implementation that lacks support
2875 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002938- Issue #2550: The approach used by client/server code for obtaining
2939 ports to listen on in network-oriented tests has been refined in an
2940 effort to facilitate running multiple instances of the entire
2941 regression test suite in parallel without issue.
2942 test_support.bind_port() has been fixed such that it will always
2943 return a unique port -- which wasn't always the case with the
2944 previous implementation, especially if socket options had been set
2945 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2946 new implementation of bind_port() will actually raise an exception
2947 if it is passed an AF_INET/SOCK_STREAM socket with either the
2948 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2949 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2950 the socket it's been passed. This currently only applies to
2951 Windows. This option prevents any other sockets from binding to the
2952 host/port we've bound to, thus removing the possibility of the
2953 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2954 when a second SOCK_STREAM socket binds and accepts to a host/port
2955 that's already been bound by another socket. The optional preferred
2956 port parameter to bind_port() has been removed. Under no
2957 circumstances should tests be hard coding ports!
2958
2959 test_support.find_unused_port() has also been introduced, which will
2960 pass a temporary socket object to bind_port() in order to obtain an
2961 unused port. The temporary socket object is then closed and
2962 deleted, and the port is returned. This method should only be used
2963 for obtaining an unused port in order to pass to an external program
2964 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2965 a parameter to a server-oriented class that doesn't give you direct
2966 access to the underlying socket used.
2967
2968 Finally, test_support.HOST has been introduced, which should be used
2969 for the host argument of any relevant socket calls (i.e. bind and
2970 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002971
2972 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002974 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2975 test_asynchat and test_socket_ssl.
2976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977 It is now possible for multiple instances of the regression test
2978 suite to run in parallel without issue.

Georg Brandl21896072010-08-01 22:31:28 +00003255 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003256
Eric Smitha73fbe72008-02-23 03:09:44 +00003257- Added the future_builtins module, which contains hex() and oct().
3258 These are the PEP 3127 version of these functions, designed to be
3259 compatible with the hex() and oct() builtins from Python 3.0. They
3260 differ slightly in their output formats from the existing, unchanged
3261 Python 2.6 builtins. The expected usage of the future_builtins
3262 module is:
3263 from future_builtins import hex, oct
3264
Eric Smith7ef40bf2008-02-20 23:34:22 +00003265- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3266 exponents for exponents with absolute value < 100. Follows C99
3267 standard. This is a change on Windows, which would use 3 digits.
3268 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3269 so that any alterations it does to the resulting string will be
3270 available in stringlib/formatter.h (for float.__format__).
3271
Eric Smith5a3c1352008-02-19 13:21:56 +00003272- Implemented PEP 3101, Advanced String Formatting. This adds a new
3273 builtin format(); a format() method for str and unicode; a
3274 __format__() method to object, str, unicode, int, long, float, and
3275 datetime; the class string.Formatter; and the C API
3276 PyObject_Format().
3277
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278- Fixed several potential crashes, all caused by specially crafted
3279 __del__ methods exploiting objects in temporarily inconsistent
3280 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003281
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003282- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003283 prevent a possible crash: an Abstract Base Class would try to access
3284 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Fixed repr() and str() of complex numbers with infinity or nan as
3287 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003288
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- Clear all free lists during a gc.collect() of the highest generation
3290 in order to allow pymalloc to free more arenas. Python may give back
3291 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Issue #2045: Fix an infinite recursion triggered when printing a
3294 subclass of collections.defaultdict, if its default_factory is set
3295 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003296
Christian Heimesf75dbef2008-02-08 00:11:31 +00003297- Fixed a minor memory leak in dictobject.c. The content of the free
3298 list was not freed on interpreter shutdown.
3299
Georg Brandl5a7eca12010-03-21 19:29:04 +00003300- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3304 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003305 to compact the internal free lists of pre-allocted ints and floats.
3306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3308 calls. Python expected the return type int but the fork familie
3309 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3312 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3315 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003316
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3318 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3321 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003322
Georg Brandl3ee81df2008-05-17 18:14:43 +00003323- Patch #1473257: generator objects gain a gi_code attribute. This is
3324 the same object as the func_code attribute of the function that
3325 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Issue #1920: "while 0" statements were completely removed by the
3328 compiler, even in the presence of an "else" clause, which is
3329 supposed to be run when the condition is false. Now the compiler
3330 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003331
Guido van Rossumeead05f2008-01-24 18:21:02 +00003332- A few crashers fixed: weakref_in_del.py (issue #1377858);
3333 loosing_dict_ref.py (issue #1303614, test67.py);
3334 borrowed_ref_[34].py (not in tracker).
3335
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003336- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003337 suppressed while an extension is loaded by calling SetErrorMode in
3338 dynload_win.c. The error is still reported properly.
3339
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003341 several extension methods and modules do not work without unicode
3342 support.
3343
Georg Brandl26543b12008-01-21 18:36:51 +00003344- Issue #1882: when compiling code from a string, encoding cookies in the
3345 second line of code were not always recognized correctly.
3346
Georg Brandl14404b62008-01-19 19:27:05 +00003347- Issue #1679: "0x" was taken as a valid integer literal.
3348
Georg Brandl6caad7d2008-01-26 14:19:22 +00003349- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003350 added.
3351
Christian Heimesc94e2b52008-01-14 04:13:37 +00003352- sys.float_info / PyFloat_GetInfo: The floating point information
3353 object was converted from a dict to a specialized structseq object.
3354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355- Patch #1816: Added sys.flags structseq. It exposes the status of
3356 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003357
Georg Brandl3ee81df2008-05-17 18:14:43 +00003358- Objects/structseq.c: Implemented new structseq representation. The
3359 patch makes structseqs (e.g. the return value of os.stat) more
3360 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Patch #1700288: added a type attribute cache that caches method
3363 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003364
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003365- Bug #1776: __import__() no longer accepts filenames on any platform.
3366 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003367
Georg Brandlaed6c662008-01-07 17:25:53 +00003368- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3369
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3371 envvar and sys.dont_write_bytecode attribute. All these can be set
3372 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003373
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Improve some exception messages when Windows fails to load an
3375 extension module. Now we get for example '%1 is not a valid Win32
3376 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003377
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3381 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003382
Christian Heimes0a8143f2007-12-18 23:22:54 +00003383- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384 and INF. float("nan"), float("inf") and float("-inf") now work on
3385 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Compiler now generates simpler and faster code for dictionary
3388 literals. The oparg for BUILD_MAP now indicates an estimated
3389 dictionary size. There is a new opcode, STORE_MAP, for adding
3390 entries to the dictionary.

3420 file can now be directly executed by passing their name to the
3421 interpreter. The directory/zipfile is automatically inserted as the
3422 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003423
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- Issue #1265: Fix a problem with sys.settrace, if the tracing
3425 function uses a generator expression when at the same time the
3426 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003427
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003428- sets and frozensets now have an isdisjoint() method.
3429
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003430- optimize the performance of builtin.sum().

3433
Georg Brandl5a7eca12010-03-21 19:29:04 +00003434- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3436 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Issue #1686386: Tuple's tp_repr did not take into account the
3439 possibility of having a self-referential tuple, which is possible
3440 from C code. Nor did object's tp_str consider that a type's tp_str
3441 could do something that could lead to an inifinite recursion.
3442 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3443 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Issue #1164: It was possible to trigger deadlock when using the
3446 'print' statement to write to a file since the GIL was not released
3447 as needed. Now PyObject_Print() does the right thing along with
3448 various tp_print implementations of the built-in types and those in
3449 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00003458- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459 PyObject_Call() never calling back out to Python code to trigger
3460 recursion depth updates/checks. Required the creation of a static
3461 RuntimeError instance in case normalizing an exception put the
3462 recursion check value past its limit. Fixes crashers
3463 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003464

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003482- Add -3 option to the interpreter to warn about features that are
3483 deprecated and will be changed/removed in Python 3.0.
3484
Georg Brandl2134e752007-05-21 20:34:16 +00003485- Patch #1686487: you can now pass any mapping after '**' in function
3486 calls.
3487
Collin Winter62903052007-05-18 23:11:24 +00003488- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489 "except E as target:". This is to provide forwards compatibility
3490 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003497- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003498 setting a plain string, ie don't expand to single letter identifiers.

Guido van Rossum143b5642007-03-23 04:58:42 +00003511- Bug #1683368: The object.__init__() and object.__new__() methods are
3512 now stricter in rejecting excess arguments. The only time when
3513 either allows excess arguments is when it is not overridden and the
3514 other one is. For backwards compatibility, when both are
3515 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003516 warning later). Also, type.__init__() insists on the same signature
3517 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3520 object to complex using its __complex__() method before falling back
3521 to the __float__() method. Therefore, the functions in the cmath
3522 module now can operate on objects that define a __complex__()
3523 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003541- Bug #1678647: write a newline after printing an exception in any
3542 case, even when converting the value to a string failed.
3543
Georg Brandl871f1bc2007-03-12 13:17:36 +00003544- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545 its argument, if it exists. If not, it will work like before. This
3546 allows customizing the output of dir() in the presence of a
3547 __getattr__().

3557 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003559- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560 makes the filenames the warning module prints much more sensible
3561 when a PYTHONSTARTUP file is used.

3575 sq_ass_slice instead of the sq_slice slot.
3576
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577- When printing an unraisable error, don't print exceptions. before

3630 embedded in the string to convert.
3631
Georg Brandl846f73a2006-10-08 07:11:54 +00003632- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003680 generator expressions (x for x, in ... ) works again. Fixing this
3681 problem required changing the .pyc magic number. This means that
3682 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004112 AttributeError instead of an IOError when the server's response
4113 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00004146- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147 are set for invalid interpolation sequences that would lead to
4148 errors on reading back those values.

4204 TestCase and TestSuite subclasses (not instances) are no longer
4205 accepted in TestSuite.addTest(). This should cause no
4206 incompatibility since it never made sense with ordinary subclasses
4207 -- the failure just occurred later, with a more cumbersome
4208 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004489- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4490 with RFC 3207 and forgets any knowledge obtained from the server not
4491 obtained from the TLS negotiation itself. Patch contributed by Bill
4492 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004495 that the SMTP.starttls() caller no longer needs to call ehlo()
4496 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497 does not claim to support starttls. Adds the
4498 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4499 Fenner.

4579 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4580 silently miscode subclasses of those types. Now, it raises a
4581 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004582

Georg Brandl3ee81df2008-05-17 18:14:43 +00004597 time so that opening a database previously created with the DB_DUP
4598 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4599 opens. Specifically: dictionary assignment to a DB object will
4600 replace all values for a given key when the database allows
4601 duplicate values. DB users should use DB.put(k, v) when they want
4602 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004603

4609 characters with ASCII value less than 32. Also, it correctly quotes
4610 dots only if they occur on a single line, as opposed to the previous
4611 behavior of quoting dots if they are the second character of any
4612 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004613

Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Removed the macfs module. It had been deprecated since Python 2.5.
