36 longer include a "manifest" to prevent them failing at import time in some
37 embedded situations.

Mark Dickinsondbbed042011-09-19 16:38:08 +010048- Issue #12973: Fix overflow checks that invoked undefined behaviour in
49 int.__pow__. These overflow checks were causing int.__pow__ to produce
50 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010051 compiler optimizing the check away. Also fix similar overflow checks
52 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
53 bugs caused test failures with recent versions of Clang.

65 cleared by the garbage collector. This fixes a segfault when an instance
66 and its type get caught in a reference cycle, and the instance's
67 deallocator calls one of the methods on the type (e.g. when subclassing
68 IOBase). Diagnosis and patch by Davide Rizzo.

78 raw_input() interrupted by CTRL+c.
79

Ned Deily87e82bb2011-06-28 19:52:59 -0700311- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
312 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
313 interpreter process. This could cause failures in non-Distutils subprocesses
314 and was unreliable since tests or user programs could modify the interpreter
315 environment after Distutils set it. Instead, have Distutils set the the
316 deployment target only in the environment of each build subprocess. It is
317 still possible to globally override the default by setting
318 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
319 greater or equal to the default value, the value with which the interpreter
320 was built.

350 the ticker doesn't have to wind down to zero from the old starting point
351 before the new interval takes effect. And if the user increases the
352 interval, it makes sure the new limit takes effect right away rather have an
353 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001264- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1265 This prevents user-created self-referencing ordered dictionaries from
1266 becoming permanently uncollectable GC garbage. The downside is that
1267 removing __del__ means that the internal doubly-linked list has to wait for
1268 GC collection rather than freeing memory immediately when the refcnt drops
1269 to zero.
1270

1337 when the underlying raw IO channel was e.g. a socket. Report and original
1338 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001728- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1729 start byte and the continuation byte(s) are now considered invalid, instead
1730 of the number of bytes specified by the start byte.
1731 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1732 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1744 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2113
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002114- Issue #7301: Add environment variable $PYTHONWARNINGS.
2115
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002116- Issue #8329: Don't return the same lists from select.select when no fds are
2117 changed.
2118
Georg Brandlfee0f442010-05-22 21:26:21 +00002119- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002120 on 64-bit machines. The shift count for either left or right shift is
2121 permitted to be up to sys.maxsize.
2122
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002123- Ensure that tokenization of identifiers is not affected by locale.

2128
Georg Brandlfee0f442010-05-22 21:26:21 +00002129- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2130 with a non-empty format string. This is an effort to future-proof user
2131 code. If a derived class does not currently implement __format__ but later
2132 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002133 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002134 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002167- Issue #8257: The Decimal construct now accepts a float instance directly,
2168 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002169

2172
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002173- collections.Counter() now supports a subtract() method.
2174
Georg Brandlfee0f442010-05-22 21:26:21 +00002175- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002184- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2185 InvalidOperation instead of returning False. (Comparisons involving a quiet
2186 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2187 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002188
Georg Brandlfee0f442010-05-22 21:26:21 +00002189- Issue #2531: Comparison operations between floats and Decimal instances now
2190 return a result based on the numeric values of the operands; previously they
2191 returned an arbitrary result based on the relative ordering of id(float) and
2192 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002193
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002194- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002195 argument `-` which tells it to read files to compile from stdin. Each line is
2196 read on demand and the named file is compiled immediately. (Original patch by
2197 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002206- Comparisons using one of <, <=, >, >= between a complex instance and a
2207 Fractions instance now raise TypeError instead of returning True/False. This
2208 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2209 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002627 file position when calling `truncate()`. It would previously change the file
2628 position to the given argument, which goes against the tradition of

2635 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Mark Dickinson1b34d252010-01-01 17:27:30 +00002732- Issue #5080: A number of functions and methods previously produced a

2734 These functions and methods now raise TypeError instead. The majority of the
2735 effects of this change are in the extension modules, but some core functions
2736 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2737 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002920- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2921 decimal string that's guaranteed to round back to x under correct rounding
2922 (with round-half-to-even rounding mode). Previously it gave a string based on
2923 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2924 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2925 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002926
Georg Brandlba83f822010-03-14 09:50:54 +00002927- Issue #7117: On almost all platforms: float-to-string and string-to-float
2928 conversions within Python are now correctly rounded. Places these conversions
2929 occur include: str for floats and complex numbers; the float and complex
2930 constructors; old-style and new-style numeric formatting; serialization and
2931 deserialization of floats and complex numbers using marshal, pickle and json;
2932 parsing of float and imaginary literals in Python code; Decimal-to-float
2933 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002934
Georg Brandlba83f822010-03-14 09:50:54 +00002935 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2936 providing correctly-rounded strtod and dtoa C functions. This code is
2937 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2938 the C compiler. There may be a small number of platforms on which correct
2939 operation of this code cannot be guaranteed, so the code is not used: notably,
2940 this applies to platforms where the C double format is not IEEE 754 binary64,
2941 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2942 and Python's configure script is unable to determine how to change the FPU
2943 precision. On these platforms conversions use the platform strtod and dtoa,
2944 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002946- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2947 uses the correctly-rounded string <-> float conversions described above (when
2948 available), and so produces correctly rounded results that will display nicely
2949 under the float repr. There are two related small changes: (1) round now
2950 accepts any class with an ``__index__()`` method for its second argument (but
2951 no longer accepts floats for the second argument), and (2) an excessively
2952 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2953 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003330- On windows, ``os.chdir()`` given unicode was not working if

3332 this code path is really executed because I cannot move to such directory on
3333 win2k)

3359 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4735
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004736- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4737 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4738 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4739 ``printf`` function, whereas PyString_FromFormat has an independent
4740 implementation and uses "%zd" on all platforms for size_t values.
4741 This makes a difference on win64, where ``printf`` needs "%Id" to display
4742 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00004762 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

4765 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4766 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004837 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4838 for catch_warnings() also led to an improvement in the raising of a
4839 DeprecationWarning related to warnings.warn_explicit().
4840
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004841- The deprecation warnings for the old camelCase threading API were removed.

4863
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004864- Issue #2975: When compiling several extension modules with Visual Studio 2008
4865 from the same python interpreter, some environment variables would grow
4866 without limit.
4867
Benjamin Peterson37346b22008-08-23 20:27:43 +00004868- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4869 exploitation of poor argument checking.
4870
Gerhard Häringef2276b2008-09-12 13:54:06 +00004871- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004905What's New in Python 2.6 beta 3?
4906================================
4907
Barry Warsaw07a4a382008-08-21 01:15:08 +00004908*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004909
4910Core and Builtins
4911-----------------
4912
Guido van Rossumf8402962008-08-20 15:01:50 +00004913- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4914 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4915 extensions do not automatically benefit from the class attribute
4916 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4917 to their tp_flags field if they care. This is a backwards
4918 compatibility feature; in 3.0, all types will use the cache by
4919 default.
4920
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004921- Keyword arguments can now follow starred arguments. (``f(a, *args,
4922 keyword=23)`` is now valid syntax.)
4923
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004924- ctypes function pointers that are COM methods have a boolean True
4925 value again.
4926
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004927- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4928 by denying s# to parse objects that have a releasebuffer procedure,
4929 and introducing s*.
4930
Georg Brandl1e13ea92008-08-11 09:07:59 +00004931- Issue #3537: Fix an assertion failure when an empty but presized dict
4932 object was stored in the freelist.
4933
Mark Dickinsonb6467572008-08-04 21:30:09 +00004934- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4935 ValueError consistently across platforms.
4936
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004937- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4938 (64bit Unix, for example), unichr() would truncate its argument and return
4939 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4940
Neal Norwitze7d8be82008-07-31 17:17:14 +00004941- Apply security patches from Apple.
4942
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004943- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4944 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4945
Antoine Pitrou92f82162008-07-25 22:22:08 +00004946- Issue #1819: function calls with several named parameters are now on
4947 average 35% faster (as measured by pybench).
4948
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004949- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4950 the python debugger steps into a class statement: the free variables (local
4951 variables defined in an outer scope) would be deleted from the outer scope.
4952
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004953- Issue #2620: Overflow checking when allocating or reallocating memory
4954 was not always being done properly in some python types and extension
4955 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4956 all been updated to perform better checks and places in the code that
4957 would previously leak memory on the error path when such an allocation
4958 failed have been fixed.
4959

4964
Benjamin Petersone977ad42008-08-20 01:42:01 +00004965- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4966 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4967
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004968- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4969 version reported by these tools does not necessarily follow the python
4970 version numbering scheme, so the module is less strict when parsing it.
4971
Nick Coghlanf70385a2008-08-18 12:42:46 +00004972- Issue #2235: Added Py3k warnings for types which will become unhashable
4973 under the stricter __hash__ inheritance rules in 3.0. Several types
4974 which did not meet the rules for hash invariants and were already
4975 unhashable in 3.0 have now been explicitly flagged as unhashable in
4976 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4977 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4978
Brett Cannon88f801d2008-08-18 00:46:22 +00004979- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4980 imported into the module but exposed as part of the module's API.
4981
Brett Cannon7b96f072008-08-18 00:41:11 +00004982- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004986- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4987
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004988- Issue #3575: Incremental decoder's decode function now takes bytearray
4989 by using 's*' instead of 't#'.
4990
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004991- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004992 fails unicode conversion on 2nd parameter. (windows only)
4993
Georg Brandl222e2082010-08-01 22:27:39 +00004994- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004995 in a redirect.
4996

Brett Cannon721b1452008-08-16 22:00:27 +00004998 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004999
Facundo Batistaeb90b782008-08-16 14:44:07 +00005000- Issue #2776: fixed small issue when handling an URL with double slash
5001 after a 302 response in the case of not going through a proxy.
5002
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005003- Issue #2676: in the email package, content-type parsing was hanging on
5004 pathological input because of quadratic or exponential behaviour of a
5005 regular expression.
5006
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005007- Issue #3476: binary buffered reading through the new "io" library is now
5008 thread-safe.
5009
Brett Cannonbf3157b2008-08-14 05:00:03 +00005010- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5011 since mimetools itself is deprecated. Because modules are cached, all
5012 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5013
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005014- Issue #3134: shutil referenced undefined WindowsError symbol.
5015
Robert Schuppenies14646332008-08-10 11:01:53 +00005016- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5017 menu entries were not deleted.
5018
Brett Cannon83e81842008-08-09 23:30:55 +00005019- Copied the implementation of reduce() to _functools.reduce() to have a
5020 version that did not raise a DeprecationWarning under -3.
5021
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005022- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5023 a MemoryError rather than silently stop the iteration.
5024
Guido van Rossum59ce9012008-08-09 14:55:34 +00005025- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5026 to _sre.compile() will now be rejected. This should not affect anybody
5027 since the re.compile() function never generates invalid re-bytecode.
5028
Skip Montanaroa032bf42008-08-08 22:52:51 +00005029- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5030 upon first access it can be automatically initialized from the csv file if
5031 it wasn't initialized during instantiation.
5032
Brett Cannon3aa2a492008-08-06 22:28:09 +00005033- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5034 the reload() built-in has been removed.
5035
Brett Cannon7e30b672008-08-04 21:52:25 +00005036- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005037 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005048 asking for a specific length. This problem only affected files opened
5049 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005050

5075 file name rather than a ZipInfo instance, so files are extracted with
5076 mode 0600 rather than 000 under Unix.
5077
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005078- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5095 regarding lack of coverage of new-style classes have also been
5096 removed, since the coverage is now fairly reasonable.

5106
Georg Brandl3e483f62008-07-16 22:57:41 +00005107- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5108 its methods now allow for items objects that can be converted to
5109 an integer using operator.index().
5110
Mark Dickinson64b7e502008-07-16 09:40:03 +00005111- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5112 produced a ValueError instead of giving the correct float.
5113
Eric Smitha5fa5a22008-07-16 00:11:49 +00005114- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

5119 numbers to and from hexadecimal strings, respectively.
5120
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005121- Issue #2235: __hash__ is once again inherited by default. To allow
5122 collections.Hashable to remain meaningful in the presence of the
5123 default hash implementation (object.__hash__), it is now possible
5124 to explicit block inheritance of hash by setting __hash__=None at
5125 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5126 level.
5127
Nick Coghlanb028f502008-07-13 14:52:36 +00005128- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5129 the parent module cannot be found while performing an absolute import.
5130 This means that an incorrectly defined __package__ attribute will
5131 now only prevent relative imports in that module rather than causing
5132 all imports from that module to fail.
5133
Nick Coghlan14ff9942008-07-08 14:21:42 +00005134- Issue #2517: Allow unicode messages in Exceptions again by correctly

5145
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005146- Issue #3004: Minor change to slice.indices(): the start and stop
5147 arguments are now treated identically, making the behaviour easier
5148 to describe and understand. For example, slice(None, -10,
5149 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5150 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5151 10, -1).

5194 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005195 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005667- Issue #1631171: Re-implement the 'warnings' module in C (the
5668 original Python code has been kept as backup). This will allow for
5669 using the 'warning's machinery in such places as the parser where
5670 use of pure Python code is not possible. Both the ``showarning()``
5671 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Issue #2550: The approach used by client/server code for obtaining
5738 ports to listen on in network-oriented tests has been refined in an
5739 effort to facilitate running multiple instances of the entire
5740 regression test suite in parallel without issue.
5741 test_support.bind_port() has been fixed such that it will always
5742 return a unique port -- which wasn't always the case with the
5743 previous implementation, especially if socket options had been set
5744 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5745 new implementation of bind_port() will actually raise an exception
5746 if it is passed an AF_INET/SOCK_STREAM socket with either the
5747 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5748 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5749 the socket it's been passed. This currently only applies to
5750 Windows. This option prevents any other sockets from binding to the
5751 host/port we've bound to, thus removing the possibility of the
5752 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5753 when a second SOCK_STREAM socket binds and accepts to a host/port
5754 that's already been bound by another socket. The optional preferred
5755 port parameter to bind_port() has been removed. Under no
5756 circumstances should tests be hard coding ports!
5757
5758 test_support.find_unused_port() has also been introduced, which will
5759 pass a temporary socket object to bind_port() in order to obtain an
5760 unused port. The temporary socket object is then closed and
5761 deleted, and the port is returned. This method should only be used
5762 for obtaining an unused port in order to pass to an external program
5763 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5764 a parameter to a server-oriented class that doesn't give you direct
5765 access to the underlying socket used.
5766
5767 Finally, test_support.HOST has been introduced, which should be used
5768 for the host argument of any relevant socket calls (i.e. bind and
5769 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005770
5771 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005772 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005773 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5774 test_asynchat and test_socket_ssl.
5775
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776 It is now possible for multiple instances of the regression test
5777 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006056- Added the future_builtins module, which contains hex() and oct().
6057 These are the PEP 3127 version of these functions, designed to be
6058 compatible with the hex() and oct() builtins from Python 3.0. They
6059 differ slightly in their output formats from the existing, unchanged
6060 Python 2.6 builtins. The expected usage of the future_builtins
6061 module is:
6062 from future_builtins import hex, oct
6063
Eric Smith7ef40bf2008-02-20 23:34:22 +00006064- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6065 exponents for exponents with absolute value < 100. Follows C99
6066 standard. This is a change on Windows, which would use 3 digits.
6067 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6068 so that any alterations it does to the resulting string will be
6069 available in stringlib/formatter.h (for float.__format__).
6070
Eric Smith5a3c1352008-02-19 13:21:56 +00006071- Implemented PEP 3101, Advanced String Formatting. This adds a new
6072 builtin format(); a format() method for str and unicode; a
6073 __format__() method to object, str, unicode, int, long, float, and
6074 datetime; the class string.Formatter; and the C API
6075 PyObject_Format().
6076
Georg Brandl3ee81df2008-05-17 18:14:43 +00006077- Fixed several potential crashes, all caused by specially crafted
6078 __del__ methods exploiting objects in temporarily inconsistent
6079 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006080
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006081- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006082 prevent a possible crash: an Abstract Base Class would try to access
6083 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006088- Clear all free lists during a gc.collect() of the highest generation
6089 in order to allow pymalloc to free more arenas. Python may give back
6090 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006091
Georg Brandl3ee81df2008-05-17 18:14:43 +00006092- Issue #2045: Fix an infinite recursion triggered when printing a
6093 subclass of collections.defaultdict, if its default_factory is set
6094 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006095
Christian Heimesf75dbef2008-02-08 00:11:31 +00006096- Fixed a minor memory leak in dictobject.c. The content of the free
6097 list was not freed on interpreter shutdown.
6098
Georg Brandl21e99f42010-03-07 15:23:59 +00006099- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6103 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006104 to compact the internal free lists of pre-allocted ints and floats.
6105
Georg Brandl3ee81df2008-05-17 18:14:43 +00006106- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6107 calls. Python expected the return type int but the fork familie
6108 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006109

Georg Brandl3ee81df2008-05-17 18:14:43 +00006122- Patch #1473257: generator objects gain a gi_code attribute. This is
6123 the same object as the func_code attribute of the function that
6124 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006125
Georg Brandl3ee81df2008-05-17 18:14:43 +00006126- Issue #1920: "while 0" statements were completely removed by the
6127 compiler, even in the presence of an "else" clause, which is
6128 supposed to be run when the condition is false. Now the compiler
6129 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006130
Guido van Rossumeead05f2008-01-24 18:21:02 +00006131- A few crashers fixed: weakref_in_del.py (issue #1377858);
6132 loosing_dict_ref.py (issue #1303614, test67.py);
6133 borrowed_ref_[34].py (not in tracker).
6134
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006135- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006136 suppressed while an extension is loaded by calling SetErrorMode in

6138
Georg Brandl3ee81df2008-05-17 18:14:43 +00006139- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006140 several extension methods and modules do not work without unicode
6141 support.
6142
Georg Brandl26543b12008-01-21 18:36:51 +00006143- Issue #1882: when compiling code from a string, encoding cookies in the

6145
Georg Brandl14404b62008-01-19 19:27:05 +00006146- Issue #1679: "0x" was taken as a valid integer literal.
6147
Georg Brandl6caad7d2008-01-26 14:19:22 +00006148- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006149 added.
6150
Christian Heimesc94e2b52008-01-14 04:13:37 +00006151- sys.float_info / PyFloat_GetInfo: The floating point information
6152 object was converted from a dict to a specialized structseq object.
6153
Georg Brandl3ee81df2008-05-17 18:14:43 +00006154- Patch #1816: Added sys.flags structseq. It exposes the status of
6155 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006156
Georg Brandl3ee81df2008-05-17 18:14:43 +00006157- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006183 and INF. float("nan"), float("inf") and float("-inf") now work on
6184 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006186- Compiler now generates simpler and faster code for dictionary
6187 literals. The oparg for BUILD_MAP now indicates an estimated
6188 dictionary size. There is a new opcode, STORE_MAP, for adding
6189 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006199- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006200 SystemError.
6201
Nick Coghlanef01d822007-12-03 12:55:17 +00006202- PEP 366: Allow explicit relative imports when executing modules

6207 running, and if the deallocation of its frames somehow calls the
6208 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006209

Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Patch #1739468: Directories and zipfiles containing a __main__.py
6219 file can now be directly executed by passing their name to the
6220 interpreter. The directory/zipfile is automatically inserted as the
6221 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006222
Georg Brandl3ee81df2008-05-17 18:14:43 +00006223- Issue #1265: Fix a problem with sys.settrace, if the tracing
6224 function uses a generator expression when at the same time the
6225 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006226
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006227- sets and frozensets now have an isdisjoint() method.

6232
Georg Brandl21e99f42010-03-07 15:23:59 +00006233- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006234 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6235 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006236
Georg Brandl3ee81df2008-05-17 18:14:43 +00006237- Issue #1686386: Tuple's tp_repr did not take into account the
6238 possibility of having a self-referential tuple, which is possible
6239 from C code. Nor did object's tp_str consider that a type's tp_str
6240 could do something that could lead to an inifinite recursion.
6241 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6242 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006243
Georg Brandl3ee81df2008-05-17 18:14:43 +00006244- Issue #1164: It was possible to trigger deadlock when using the
6245 'print' statement to write to a file since the GIL was not released
6246 as needed. Now PyObject_Print() does the right thing along with
6247 various tp_print implementations of the built-in types and those in
6248 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006249
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250- Issue #1147: Exceptions were directly allowing string exceptions in
6251 their throw() method even though string exceptions no longer
6252 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006253
Georg Brandl3ee81df2008-05-17 18:14:43 +00006254- Issue #1096: Prevent a segfault from getting the repr of a very
6255 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006256
Brett Cannon1e534b52007-09-07 04:18:30 +00006257- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006258 PyObject_Call() never calling back out to Python code to trigger
6259 recursion depth updates/checks. Required the creation of a static
6260 RuntimeError instance in case normalizing an exception put the
6261 recursion check value past its limit. Fixes crashers
6262 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006277- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278 __*__ attributes. (Some already existed, e.g., __doc__ and
6279 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006280
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006281- Add -3 option to the interpreter to warn about features that are
6282 deprecated and will be changed/removed in Python 3.0.
6283
Georg Brandl2134e752007-05-21 20:34:16 +00006284- Patch #1686487: you can now pass any mapping after '**' in function
6285 calls.
6286
Collin Winter62903052007-05-18 23:11:24 +00006287- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288 "except E as target:". This is to provide forwards compatibility
6289 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006290
Brett Cannon229cee22007-05-05 01:34:02 +00006291- Deprecate BaseException.message as per PEP 352.
6292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006294 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006295
Vinay Sajip8549ce32007-05-06 17:53:37 +00006296- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006297 setting a plain string, ie don't expand to single letter identifiers.
6298
Raymond Hettinger13936692007-04-11 18:40:58 +00006299- Request #1191699: Slices can now be pickled.
6300
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006301- Request #1193128: str.translate() now allows a None argument for
6302 translations that only remove characters without re-mapping the
6303 remaining characters.
6304
Georg Brandl5cb76c12007-03-21 09:00:39 +00006305- Patch #1682205: a TypeError while unpacking an iterable is no longer
6306 masked by a generic one with the message "unpack non-sequence".
6307
Neal Norwitzaa754b72007-03-21 06:39:48 +00006308- Remove unused file Python/fmod.c.
6309
Guido van Rossum143b5642007-03-23 04:58:42 +00006310- Bug #1683368: The object.__init__() and object.__new__() methods are
6311 now stricter in rejecting excess arguments. The only time when
6312 either allows excess arguments is when it is not overridden and the
6313 other one is. For backwards compatibility, when both are
6314 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006315 warning later). Also, type.__init__() insists on the same signature
6316 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6319 object to complex using its __complex__() method before falling back
6320 to the __float__() method. Therefore, the functions in the cmath
6321 module now can operate on objects that define a __complex__()
6322 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Patch #1623563: allow __class__ assignment for classes with
6325 __slots__. The old and the new class are still required to have the
6326 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006327
Georg Brandl3ee81df2008-05-17 18:14:43 +00006328- Patch #1642547: Fix an error/crash when encountering syntax errors

6332 ``object.__reduce_ex__()`` is called with an object that is faking
6333 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006334
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335- Patch #1680015: Don't modify __slots__ tuple if it contains an

6339
Georg Brandl7b9c5552007-03-12 14:30:05 +00006340- Bug #1678647: write a newline after printing an exception in any
6341 case, even when converting the value to a string failed.
6342
Georg Brandl871f1bc2007-03-12 13:17:36 +00006343- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006344 its argument, if it exists. If not, it will work like before. This
6345 allows customizing the output of dir() in the presence of a
6346 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006347
Collin Winter276887b2007-03-12 16:11:39 +00006348- Patch #922167: Python no longer segfaults when faced with infinitely
6349 self-recursive reload() calls (as reported by bug #742342).
6350
Georg Brandl3ee81df2008-05-17 18:14:43 +00006351- Patch #1675981: remove unreachable code from ``type.__new__()``
6352 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Patch #1491866: change the complex() constructor to allow
6355 parthensized forms. This means complex(repr(x)) now works instead of
6356 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006357
Georg Brandlaa2321b2007-03-07 00:40:28 +00006358- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359 makes the filenames the warning module prints much more sensible
6360 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006361

6363 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006364 variable is given, but break into the interactive interpreter just
6365 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006372
Georg Brandl0fca97a2007-03-05 22:28:08 +00006373- Patch #1674228: when assigning a slice (old-style), check for the
6374 sq_ass_slice instead of the sq_slice slot.
6375
Georg Brandl3ee81df2008-05-17 18:14:43 +00006376- When printing an unraisable error, don't print exceptions. before
6377 the name. This duplicates the behavior whening normally printing
6378 exceptions.

6944
Georg Brandl92a6bae2007-03-13 17:43:32 +00006945- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006946 are set for invalid interpolation sequences that would lead to
6947 errors on reading back those values.

7001
Georg Brandl3ee81df2008-05-17 18:14:43 +00007002- unittest now verifies more of its assumptions. In particular,
7003 TestCase and TestSuite subclasses (not instances) are no longer
7004 accepted in TestSuite.addTest(). This should cause no
7005 incompatibility since it never made sense with ordinary subclasses
7006 -- the failure just occurred later, with a more cumbersome
7007 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007294 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007296 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007395- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396 time so that opening a database previously created with the DB_DUP
7397 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7398 opens. Specifically: dictionary assignment to a DB object will
7399 replace all values for a given key when the database allows
7400 duplicate values. DB users should use DB.put(k, v) when they want
7401 to store duplicates; not DB[k] = v.

7409 dots only if they occur on a single line, as opposed to the previous
7410 behavior of quoting dots if they are the second character of any

Georg Brandl3ee81df2008-05-17 18:14:43 +00007681 periodic threadstate and signal checking in tight loops. By
7682 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7742 to ``PyTuple_SetItem``, it can be used to populate a brand new

7757 of w# format code incorrectly truncated the length to an int, even
7758 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7759 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7790 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
