Victor Stinner66c6e9d2013-12-13 02:37:09 +010012- Issue #14432: Generator now clears the borrowed reference to the thread
13 state. Fix a crash when a generator is created in a C thread that is
14 destroyed while the generator is still used. The issue was that a generator
15 contains a frame, and the frame kept a reference to the Python state of the
16 destroyed C thread. The crash occurs when a trace function is setup.
17
Victor Stinner7821ff32013-12-10 01:23:22 +010018- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.

Gregory P. Smith9ffb1482013-12-10 18:22:03 -080026- Issue #17200: telnetlib's read_until and expect timeout was broken by the
27 fix to Issue #14635 in Python 2.7.4 to be interpreted as milliseconds
28 instead of seconds when the platform supports select.poll (ie: everywhere).
29 It is now treated as seconds once again.

39 no exception detail exists (no colon following the exception's name, or
40 a colon does follow but no text follows the colon).
41
Alexandre Vassalotti1d3a1732013-11-30 13:24:13 -080042- Issue #16231: Fixed pickle.Pickler to only fallback to its default pickling
43 behaviour when Pickler.persistent_id returns None, but not for any other
Alexandre Vassalotti34ca0662013-11-30 14:02:47 -080044 false values. This allows false values other than None to be used as
45 persistent IDs. This behaviour is consistent with cPickle.
Alexandre Vassalotti1d3a1732013-11-30 13:24:13 -080046

Nadeem Vawda6cad3712012-11-05 00:55:06 +01001170 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001171 to the last call. decompressobj().flush() now correctly sets unused_data and

Ned Deily18fae3f2013-01-31 01:24:55 -08001495- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1496 In particular, fix extension module build failures when trying to use
1497 32-bit-only installer Pythons on systems with Xcode 4 (currently
1498 OS X 10.8, 10.7, and optionally 10.6).
1499 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1500 * Since Xcode 4 removes ppc support, extension module builds now
1501 check for ppc compiler support and by default remove ppc and
1502 ppc64 archs when they are not available.
1503 * Extension module builds now revert to using system installed
1504 headers and libs (/usr and /System/Library) if the SDK used
1505 to build the interpreter is not installed or has moved.
1506 * Try to avoid building extension modules with deprecated
1507 and problematic Apple llvm-gcc compiler. If original compiler
1508 is not available, use clang instead by default.

1863 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001939- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1940 Distutils-based packages with C extension modules may fail because
1941 Apple has removed gcc-4.2, the version used to build python.org
1942 64-bit/32-bit Pythons. If the user does not explicitly override
1943 the default C compiler by setting the CC environment variable,
1944 Distutils will now attempt to compile extension modules with clang
1945 if gcc-4.2 is required but not found. Also as a convenience, if
1946 the user does explicitly set CC, substitute its value as the default
1947 compiler in the Distutils LDSHARED configuration variable for OS X.
1948 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1949 SDK, neither of which are available in Xcode 4. This change does not
1950 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002200- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2201 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2202 interpreter process. This could cause failures in non-Distutils subprocesses
2203 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002204 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002205 deployment target only in the environment of each build subprocess. It is
2206 still possible to globally override the default by setting
2207 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2208 greater or equal to the default value, the value with which the interpreter
2209 was built.

2238 updating the check interval, so if the user decreases the check interval,
2239 the ticker doesn't have to wind down to zero from the old starting point
2240 before the new interval takes effect. And if the user increases the
2241 interval, it makes sure the new limit takes effect right away rather have an
2242 early task switch before recognizing the new interval.

3206 handles non-blocking readinto() returning None correctly.
3207
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00003208- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
3209 SSLSocket.sendto() to match the corresponding socket methods. Also,
3210 fix various SSLSocket methods to raise socket.error rather than an
3211 unhelpful TypeError when called on an unconnected socket. Original patch
3212 by Andrew Bennetts.

3221
Raymond Hettinger20397532010-09-12 02:11:45 +00003222- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3223 This prevents user-created self-referencing ordered dictionaries from
3224 becoming permanently uncollectable GC garbage. The downside is that
3225 removing __del__ means that the internal doubly-linked list has to wait for
3226 GC collection rather than freeing memory immediately when the refcnt drops
3227 to zero.
3228

3232
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003233- Issue #9792: In case of connection failure, socket.create_connection()
3234 would swallow the exception and raise a new one, making it impossible
3235 to fetch the original errno, or to filter timeout errors. Now the
3236 original error is re-raised.
3237
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003238- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3240 be updated back after the system call. Original patch by Brian Brazil.

3256 falling into recursion.
3257
R. David Murray7c4bf552010-08-25 01:45:57 +00003258- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3259 character years even if the message contains RFC822 two character years.
3260
Daniel Stutzbach91287322010-08-24 21:09:30 +00003261- Issue #8750: Fixed MutableSet's methods to correctly handle

3273 module now correctly return a set. (Patch by Eli Bendersky.)
3274
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003275- Issue #9617: Signals received during a low-level write operation aren't
3276 ignored by the buffered IO layer anymore.
3277
Benjamin Peterson52c36052010-08-21 03:03:22 +00003278- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3279 are not held onto after they are deleted elsewhere.
3280
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003281- Issue #9626: the view methods for collections.OrderedDict() were returning

3288
Antoine Pitroue1436d12010-08-12 15:25:51 +00003289- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3290 and a BadZipfile error is raised if it doesn't match (as used to be the
3291 case in Python 2.5 and earlier).

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003293- Issue #9550: a BufferedReader could issue an additional read when the
3294 original read request had been satisfied, which could block indefinitely
3295 when the underlying raw IO channel was e.g. a socket. Report and original
3296 patch by Jason V. Miller.
3297
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003298- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003316- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3317 This is how it is supposed to work, wget and curl do the same. Previous
3318 behavior was wrong.

3326 the option character for the added 'h/help' option if prefix_chars
3327 does not contain a '-', instead of raising an error.

3701 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004046 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4047 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4048 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4069-----------------
4070
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004071- Issue #7301: Add environment variable $PYTHONWARNINGS.
4072
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004073- Issue #8329: Don't return the same lists from select.select when no fds are
4074 changed.
4075
Georg Brandlfee0f442010-05-22 21:26:21 +00004076- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004077 on 64-bit machines. The shift count for either left or right shift is
4078 permitted to be up to sys.maxsize.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004084- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4085
Georg Brandlfee0f442010-05-22 21:26:21 +00004086- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4087 with a non-empty format string. This is an effort to future-proof user
4088 code. If a derived class does not currently implement __format__ but later
4089 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004090 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004091 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004092

Victor Stinner66644262010-03-10 22:30:19 +00004106- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004107 (SIGINT). If an error occurs while importing the site module, the error is

4123
Georg Brandlfee0f442010-05-22 21:26:21 +00004124- Issue #8257: The Decimal construct now accepts a float instance directly,
4125 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004126
4127 >>> Decimal(1.1)
4128 Decimal('1.100000000000000088817841970012523233890533447265625')
4129
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004130- collections.Counter() now supports a subtract() method.
4131
Georg Brandlfee0f442010-05-22 21:26:21 +00004132- The functools module now has a total_ordering() class decorator to simplify
4133 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004135- The functools module also adds cmp_to_key() as a tool to transition old-style
4136 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004137
Georg Brandlfee0f442010-05-22 21:26:21 +00004138- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4139 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004140
Georg Brandlfee0f442010-05-22 21:26:21 +00004141- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4142 InvalidOperation instead of returning False. (Comparisons involving a quiet
4143 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4144 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004145
Georg Brandlfee0f442010-05-22 21:26:21 +00004146- Issue #2531: Comparison operations between floats and Decimal instances now
4147 return a result based on the numeric values of the operands; previously they
4148 returned an arbitrary result based on the relative ordering of id(float) and
4149 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004150
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004151- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004152 argument `-` which tells it to read files to compile from stdin. Each line is
4153 read on demand and the named file is compiled immediately. (Original patch by
4154 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004155
Georg Brandlfee0f442010-05-22 21:26:21 +00004156- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004159- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4160 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004161 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004162
Georg Brandlfee0f442010-05-22 21:26:21 +00004163- Comparisons using one of <, <=, >, >= between a complex instance and a
4164 Fractions instance now raise TypeError instead of returning True/False. This
4165 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4166 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004167

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004177- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004178 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4179 silenced.

Georg Brandlfee0f442010-05-22 21:26:21 +00004222 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4223 log file to compute the next rollover time. If the log file does not exist,

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004265- Issue #8300: When passing a non-integer argument to struct.pack with any
4266 integer format code, struct.pack first attempts to convert the non-integer
4267 using its __index__ method. If that method is non-existent or raises
4268 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004270- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4271 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4272 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004273 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4274 inconsistent: __int__ was used for some integer codes but not for others, and
4275 the set of integer codes for which it was used differed between native packing
4276 and standard packing.)

4508 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004509 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004528- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4529 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4530 returning NULL. The macro now returns a statically allocated empty string
4531 instead.

4541 strings,
4542 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4543 numeric strings corresponding to subnormal values,
4544 (3) a memory leak for some values large enough to cause overflow, and
4545 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004583- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004584 file position when calling `truncate()`. It would previously change the file
4585 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004586 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4587
Georg Brandlba83f822010-03-14 09:50:54 +00004588- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4589 class used to represent files stored inside an archive. The new
4590 implementation is significantly faster and can be wrapped in a
4591 ``io.BufferedReader`` object for more speedups. It also solves an issue
4592 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4593 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004603- Issue #7748: Since unicode values are supported for some metadata options in
4604 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4605 encoded string for them. This ensures that the upload and register commands
4606 send the correct values to PyPI without any error.

4693 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4694 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004876- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4877 decimal string that's guaranteed to round back to x under correct rounding
4878 (with round-half-to-even rounding mode). Previously it gave a string based on
4879 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4880 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4881 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004882
Georg Brandlba83f822010-03-14 09:50:54 +00004883- Issue #7117: On almost all platforms: float-to-string and string-to-float
4884 conversions within Python are now correctly rounded. Places these conversions
4885 occur include: str for floats and complex numbers; the float and complex
4886 constructors; old-style and new-style numeric formatting; serialization and
4887 deserialization of floats and complex numbers using marshal, pickle and json;
4888 parsing of float and imaginary literals in Python code; Decimal-to-float
4889 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004890
Georg Brandlba83f822010-03-14 09:50:54 +00004891 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4892 providing correctly-rounded strtod and dtoa C functions. This code is
4893 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4894 the C compiler. There may be a small number of platforms on which correct
4895 operation of this code cannot be guaranteed, so the code is not used: notably,
4896 this applies to platforms where the C double format is not IEEE 754 binary64,
4897 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4898 and Python's configure script is unable to determine how to change the FPU
4899 precision. On these platforms conversions use the platform strtod and dtoa,
4900 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004901
Georg Brandlba83f822010-03-14 09:50:54 +00004902- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4903 uses the correctly-rounded string <-> float conversions described above (when
4904 available), and so produces correctly rounded results that will display nicely
4905 under the float repr. There are two related small changes: (1) round now
4906 accepts any class with an ``__index__()`` method for its second argument (but
4907 no longer accepts floats for the second argument), and (2) an excessively
4908 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4909 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005056- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5057 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5058 but with at least one decimal point and with a default precision
5059 of 12. Previously, the behavior the same but with a default precision of 6.
5060 This more closely matches ``str()``, and reduces surprises when adding
5061 alignment flags to the empty presentation type. This also affects the new
5062 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00005202- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5203 existing .py counterpart, override the co_filename attributes of all code

5259
Georg Brandlba83f822010-03-14 09:50:54 +00005260- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5261 file objects with closefd=False. The file descriptor is still kept open but
5262 the file object behaves like a closed file. The ``FileIO`` object also got a
5263 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005286- On windows, ``os.chdir()`` given unicode was not working if
5287 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5288 this code path is really executed because I cannot move to such directory on
5289 win2k)

5292 element is temporarily replaced with an equivalent frozenset. But the
5293 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005314- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5315 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5316 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5317 of using the replace error handler in PyUnicode_DecodeUTF8().
5318
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005319- Issue #3739: The unicode-internal encoder now reports the number of characters

5321
Georg Brandlba83f822010-03-14 09:50:54 +00005322- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5324 gives improved memory leak detection when running under Valgrind, while taking
5325 advantage of pymalloc at other times.

6571 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006572 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6573 the tests if DISPLAY is defined but can't be used.

6694
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006695- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6696 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6697 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6698 ``printf`` function, whereas PyString_FromFormat has an independent
6699 implementation and uses "%zd" on all platforms for size_t values.
6700 This makes a difference on win64, where ``printf`` needs "%Id" to display
6701 64bit values.

6707 object; previously an int would be returned for small values. the __long__
6708 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006718 was correctly parsed but parsing of subsequent arguments failed.
6719
Vinay Sajip35e3b032008-09-01 14:33:59 +00006720- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006721 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6722 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6723 when given a tuple of classes as second argument, were looking up
6724 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6725 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006864What's New in Python 2.6 beta 3?
6865================================
6866
Barry Warsaw07a4a382008-08-21 01:15:08 +00006867*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006868
6869Core and Builtins
6870-----------------
6871
Guido van Rossumf8402962008-08-20 15:01:50 +00006872- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6873 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6874 extensions do not automatically benefit from the class attribute
6875 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6876 to their tp_flags field if they care. This is a backwards
6877 compatibility feature; in 3.0, all types will use the cache by
6878 default.
6879
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006880- Keyword arguments can now follow starred arguments. (``f(a, *args,
6881 keyword=23)`` is now valid syntax.)
6882
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006883- ctypes function pointers that are COM methods have a boolean True
6884 value again.
6885
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006886- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6887 by denying s# to parse objects that have a releasebuffer procedure,
6888 and introducing s*.
6889
Georg Brandl1e13ea92008-08-11 09:07:59 +00006890- Issue #3537: Fix an assertion failure when an empty but presized dict
6891 object was stored in the freelist.
6892
Mark Dickinsonb6467572008-08-04 21:30:09 +00006893- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6894 ValueError consistently across platforms.
6895
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006896- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6897 (64bit Unix, for example), unichr() would truncate its argument and return
6898 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6899
Neal Norwitze7d8be82008-07-31 17:17:14 +00006900- Apply security patches from Apple.
6901
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006902- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6903 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6904
Antoine Pitrou92f82162008-07-25 22:22:08 +00006905- Issue #1819: function calls with several named parameters are now on
6906 average 35% faster (as measured by pybench).
6907
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006908- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6909 the python debugger steps into a class statement: the free variables (local
6910 variables defined in an outer scope) would be deleted from the outer scope.
6911
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006912- Issue #2620: Overflow checking when allocating or reallocating memory
6913 was not always being done properly in some python types and extension
6914 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6915 all been updated to perform better checks and places in the code that
6916 would previously leak memory on the error path when such an allocation
6917 failed have been fixed.
6918
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006919Library
6920-------
6921
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006922- Issue #3612: Added some missing basic types in ctypes.wintypes.
6923
Benjamin Petersone977ad42008-08-20 01:42:01 +00006924- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6925 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6926
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006927- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6928 version reported by these tools does not necessarily follow the python
6929 version numbering scheme, so the module is less strict when parsing it.
6930
Nick Coghlanf70385a2008-08-18 12:42:46 +00006931- Issue #2235: Added Py3k warnings for types which will become unhashable
6932 under the stricter __hash__ inheritance rules in 3.0. Several types
6933 which did not meet the rules for hash invariants and were already
6934 unhashable in 3.0 have now been explicitly flagged as unhashable in
6935 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6936 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6937
Brett Cannon88f801d2008-08-18 00:46:22 +00006938- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6939 imported into the module but exposed as part of the module's API.
6940
Brett Cannon7b96f072008-08-18 00:41:11 +00006941- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6942
Brett Cannon46225e72008-08-18 00:36:52 +00006943- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6944
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006945- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6946
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006947- Issue #3575: Incremental decoder's decode function now takes bytearray
6948 by using 's*' instead of 't#'.
6949
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006950- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006951 fails unicode conversion on 2nd parameter. (windows only)
6952
Georg Brandl222e2082010-08-01 22:27:39 +00006953- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006954 in a redirect.
6955
Brett Cannonabe423e2008-08-16 21:47:07 +00006956- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006957 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006958
Facundo Batistaeb90b782008-08-16 14:44:07 +00006959- Issue #2776: fixed small issue when handling an URL with double slash
6960 after a 302 response in the case of not going through a proxy.
6961
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006962- Issue #2676: in the email package, content-type parsing was hanging on
6963 pathological input because of quadratic or exponential behaviour of a
6964 regular expression.
6965
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006966- Issue #3476: binary buffered reading through the new "io" library is now
6967 thread-safe.
6968
Brett Cannonbf3157b2008-08-14 05:00:03 +00006969- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6970 since mimetools itself is deprecated. Because modules are cached, all
6971 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6972
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006973- Issue #3134: shutil referenced undefined WindowsError symbol.
6974
Robert Schuppenies14646332008-08-10 11:01:53 +00006975- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6976 menu entries were not deleted.
6977
Brett Cannon83e81842008-08-09 23:30:55 +00006978- Copied the implementation of reduce() to _functools.reduce() to have a
6979 version that did not raise a DeprecationWarning under -3.
6980
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006981- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6982 a MemoryError rather than silently stop the iteration.
6983
Guido van Rossum59ce9012008-08-09 14:55:34 +00006984- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6985 to _sre.compile() will now be rejected. This should not affect anybody
6986 since the re.compile() function never generates invalid re-bytecode.
6987
Skip Montanaroa032bf42008-08-08 22:52:51 +00006988- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6989 upon first access it can be automatically initialized from the csv file if
6990 it wasn't initialized during instantiation.
6991
Brett Cannon3aa2a492008-08-06 22:28:09 +00006992- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6993 the reload() built-in has been removed.
6994
Brett Cannon7e30b672008-08-04 21:52:25 +00006995- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006996 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6999 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7000 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7001 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007002
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007003- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7004 raised an AttributeError.
7005
Benjamin Peterson01a24322008-07-28 23:35:27 +00007006- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007007 asking for a specific length. This problem only affected files opened
7008 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007009
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007010- Issue #3449: Update decimal module to use most recent specification
7011 (v. 1.68) and tests (v. 2.58) from IBM.
7012
Georg Brandl222e2082010-08-01 22:27:39 +00007013- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007014

7017
Georg Brandlf9efabb2008-07-23 15:16:45 +00007018- Deprecate the "ast" parser function aliases.
7019
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007020- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7021
7022- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7023 invalid arguments.
7024
7025- Issue #3302: Fix several crashes when calling locale's gettext functions
7026 with None arguments.
7027
7028- Issue #3389: Allow resolving dotted names for handlers in logging
7029 configuration files.
7030
7031- Deprecate the sunaudio module for removal in Python 3.0.
7032
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007033- Issue #3394: zipfile.writestr sets external attributes when passed a
7034 file name rather than a ZipInfo instance, so files are extracted with
7035 mode 0600 rather than 000 under Unix.
7036
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007037- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7038 argument in python 2.5, this broke code that subclassed Popen to include its
7039 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7048
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007049- Issue #2235: the C API function PyObject_HashNotImplemented and its
7050 interaction with the tp_hash slot (added in 2.6b2) are now documented
7051
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007052- Issue #643841: The language reference now provides more detailed
7053 coverage of the lookup process for special methods. The disclaimers
7054 regarding lack of coverage of new-style classes have also been
7055 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007058What's New in Python 2.6 beta 2?
7059================================
7060
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007061*Release date: 17-Jul-2008*
7062
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007063Core and Builtins
7064-----------------
7065
Georg Brandl3e483f62008-07-16 22:57:41 +00007066- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7067 its methods now allow for items objects that can be converted to
7068 an integer using operator.index().
7069
Mark Dickinson64b7e502008-07-16 09:40:03 +00007070- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7071 produced a ValueError instead of giving the correct float.
7072
Eric Smitha5fa5a22008-07-16 00:11:49 +00007073- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7074 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7075
Mark Dickinson7103aa42008-07-15 19:08:33 +00007076- Issue #3008: the float type has a new instance method 'float.hex'
7077 and a new class method 'float.fromhex' to convert floating-point
7078 numbers to and from hexadecimal strings, respectively.
7079
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007080- Issue #2235: __hash__ is once again inherited by default. To allow
7081 collections.Hashable to remain meaningful in the presence of the
7082 default hash implementation (object.__hash__), it is now possible
7083 to explicit block inheritance of hash by setting __hash__=None at
7084 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7085 level.
7086
Nick Coghlanb028f502008-07-13 14:52:36 +00007087- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7088 the parent module cannot be found while performing an absolute import.
7089 This means that an incorrectly defined __package__ attribute will
7090 now only prevent relative imports in that module rather than causing
7091 all imports from that module to fail.
7092
Nick Coghlan14ff9942008-07-08 14:21:42 +00007093- Issue #2517: Allow unicode messages in Exceptions again by correctly
7094 bypassing the instance dictionary when looking up __unicode__ on
7095 new-style classes.
7096
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007097- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7098 set to a custom object whose write() method happens to install
7099 another file in sys.stdout.
7100
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007101- Issue #3088: Corrected a race condition in classes derived from
7102 threading.local: the first member set by a thread could be saved in
7103 another thread's dictionary.
7104
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007105- Issue #3004: Minor change to slice.indices(): the start and stop
7106 arguments are now treated identically, making the behaviour easier
7107 to describe and understand. For example, slice(None, -10,
7108 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7109 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7110 10, -1).
7111
Georg Brandl278fc502008-07-19 12:46:12 +00007112- Issue #3219: Calling a function with repeated keyword arguments,
7113 f(a=2, a=23), would not cause a syntax error. This was a regression
7114 from 2.4 caused by the switch to the new compiler.

7124 api functions without holding the GIL, which could lead to a fatal
7125 error when they failed.
7126
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007127- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7561 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007562 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007563
7564 This is controlled by the configure argument ``--with-universal-archs``:
7565
7566 - ``--with-universal-archs=all``: install 4-way universal
7567
7568 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7569
7570 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7571
7572 This option should be used in combination with ``--enable-universalsdk=``.
7573
7574 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 +00007623- Issue #1631171: Re-implement the 'warnings' module in C (the
7624 original Python code has been kept as backup). This will allow for
7625 using the 'warning's machinery in such places as the parser where
7626 use of pure Python code is not possible. Both the ``showarning()``
7627 and ``formatwarning()`` gain an optional 'line' argument which is
7628 not called by default for backwards-compatibility reasons. Setting
7629 ``warnings.showwarning()`` to an implementation that lacks support
7630 for the ``line`` argument will raise a DeprecationWarning.

7654
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007655- The getpass module has been improved on Unix. It now uses /dev/tty
7656 by default and uses stderr instead of stdout. A GetPassWarning is
7657 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- Issue #2385: distutils.core.run_script() makes __file__ available,
7686 so the controlled environment will more closely mirror the typical
7687 script environment. This supports setup.py scripts that refer to
7688 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007693- Issue #2550: The approach used by client/server code for obtaining
7694 ports to listen on in network-oriented tests has been refined in an
7695 effort to facilitate running multiple instances of the entire
7696 regression test suite in parallel without issue.
7697 test_support.bind_port() has been fixed such that it will always
7698 return a unique port -- which wasn't always the case with the
7699 previous implementation, especially if socket options had been set
7700 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7701 new implementation of bind_port() will actually raise an exception
7702 if it is passed an AF_INET/SOCK_STREAM socket with either the
7703 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7704 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7705 the socket it's been passed. This currently only applies to
7706 Windows. This option prevents any other sockets from binding to the
7707 host/port we've bound to, thus removing the possibility of the
7708 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7709 when a second SOCK_STREAM socket binds and accepts to a host/port
7710 that's already been bound by another socket. The optional preferred
7711 port parameter to bind_port() has been removed. Under no
7712 circumstances should tests be hard coding ports!
7713
7714 test_support.find_unused_port() has also been introduced, which will
7715 pass a temporary socket object to bind_port() in order to obtain an
7716 unused port. The temporary socket object is then closed and
7717 deleted, and the port is returned. This method should only be used
7718 for obtaining an unused port in order to pass to an external program
7719 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7720 a parameter to a server-oriented class that doesn't give you direct
7721 access to the underlying socket used.
7722
7723 Finally, test_support.HOST has been introduced, which should be used
7724 for the host argument of any relevant socket calls (i.e. bind and
7725 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007726
7727 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007729 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7730 test_asynchat and test_socket_ssl.
7731
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732 It is now possible for multiple instances of the regression test
7733 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00008002- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008003 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00008012- Added the future_builtins module, which contains hex() and oct().
8013 These are the PEP 3127 version of these functions, designed to be
8014 compatible with the hex() and oct() builtins from Python 3.0. They
8015 differ slightly in their output formats from the existing, unchanged
8016 Python 2.6 builtins. The expected usage of the future_builtins
8017 module is:
8018 from future_builtins import hex, oct
8019
Eric Smith7ef40bf2008-02-20 23:34:22 +00008020- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8021 exponents for exponents with absolute value < 100. Follows C99
8022 standard. This is a change on Windows, which would use 3 digits.
8023 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8024 so that any alterations it does to the resulting string will be
8025 available in stringlib/formatter.h (for float.__format__).
8026
Eric Smith5a3c1352008-02-19 13:21:56 +00008027- Implemented PEP 3101, Advanced String Formatting. This adds a new
8028 builtin format(); a format() method for str and unicode; a
8029 __format__() method to object, str, unicode, int, long, float, and
8030 datetime; the class string.Formatter; and the C API
8031 PyObject_Format().
8032
Georg Brandl3ee81df2008-05-17 18:14:43 +00008033- Fixed several potential crashes, all caused by specially crafted
8034 __del__ methods exploiting objects in temporarily inconsistent
8035 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008036
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008037- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008038 prevent a possible crash: an Abstract Base Class would try to access
8039 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008040

Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Clear all free lists during a gc.collect() of the highest generation
8045 in order to allow pymalloc to free more arenas. Python may give back
8046 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Issue #2045: Fix an infinite recursion triggered when printing a
8049 subclass of collections.defaultdict, if its default_factory is set
8050 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008051
Christian Heimesf75dbef2008-02-08 00:11:31 +00008052- Fixed a minor memory leak in dictobject.c. The content of the free
8053 list was not freed on interpreter shutdown.
8054
Georg Brandl21e99f42010-03-07 15:23:59 +00008055- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008056 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8059 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008060 to compact the internal free lists of pre-allocted ints and floats.
8061
Georg Brandl3ee81df2008-05-17 18:14:43 +00008062- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8063 calls. Python expected the return type int but the fork familie
8064 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008065
Georg Brandl3ee81df2008-05-17 18:14:43 +00008066- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008078- Patch #1473257: generator objects gain a gi_code attribute. This is
8079 the same object as the func_code attribute of the function that
8080 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008081
Georg Brandl3ee81df2008-05-17 18:14:43 +00008082- Issue #1920: "while 0" statements were completely removed by the
8083 compiler, even in the presence of an "else" clause, which is
8084 supposed to be run when the condition is false. Now the compiler
8085 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008086
Guido van Rossumeead05f2008-01-24 18:21:02 +00008087- A few crashers fixed: weakref_in_del.py (issue #1377858);
8088 loosing_dict_ref.py (issue #1303614, test67.py);
8089 borrowed_ref_[34].py (not in tracker).
8090
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008091- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008092 suppressed while an extension is loaded by calling SetErrorMode in
8093 dynload_win.c. The error is still reported properly.
8094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008096 several extension methods and modules do not work without unicode
8097 support.
8098
Georg Brandl26543b12008-01-21 18:36:51 +00008099- Issue #1882: when compiling code from a string, encoding cookies in the
8100 second line of code were not always recognized correctly.
8101
Georg Brandl14404b62008-01-19 19:27:05 +00008102- Issue #1679: "0x" was taken as a valid integer literal.
8103
Georg Brandl6caad7d2008-01-26 14:19:22 +00008104- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008105 added.
8106
Christian Heimesc94e2b52008-01-14 04:13:37 +00008107- sys.float_info / PyFloat_GetInfo: The floating point information
8108 object was converted from a dict to a specialized structseq object.
8109
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110- Patch #1816: Added sys.flags structseq. It exposes the status of
8111 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008112
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113- Objects/structseq.c: Implemented new structseq representation. The

8115 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008116
Georg Brandl3ee81df2008-05-17 18:14:43 +00008117- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008139 and INF. float("nan"), float("inf") and float("-inf") now work on
8140 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008141
Georg Brandl3ee81df2008-05-17 18:14:43 +00008142- Compiler now generates simpler and faster code for dictionary
8143 literals. The oparg for BUILD_MAP now indicates an estimated
8144 dictionary size. There is a new opcode, STORE_MAP, for adding
8145 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00008187- Fix warnings found by the new version of the Coverity checker.
8188
Georg Brandl21e99f42010-03-07 15:23:59 +00008189- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008190 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8191 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008192
Georg Brandl3ee81df2008-05-17 18:14:43 +00008193- Issue #1686386: Tuple's tp_repr did not take into account the
8194 possibility of having a self-referential tuple, which is possible
8195 from C code. Nor did object's tp_str consider that a type's tp_str
8196 could do something that could lead to an inifinite recursion.
8197 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8198 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008199
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200- Issue #1164: It was possible to trigger deadlock when using the
8201 'print' statement to write to a file since the GIL was not released
8202 as needed. Now PyObject_Print() does the right thing along with
8203 various tp_print implementations of the built-in types and those in
8204 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008205
Georg Brandl3ee81df2008-05-17 18:14:43 +00008206- Issue #1147: Exceptions were directly allowing string exceptions in
8207 their throw() method even though string exceptions no longer
8208 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Issue #1096: Prevent a segfault from getting the repr of a very
8211 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008212
Brett Cannon1e534b52007-09-07 04:18:30 +00008213- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008214 PyObject_Call() never calling back out to Python code to trigger
8215 recursion depth updates/checks. Required the creation of a static
8216 RuntimeError instance in case normalizing an exception put the
8217 recursion check value past its limit. Fixes crashers
8218 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008219

Neal Norwitz0ac60192007-05-27 04:08:54 +00008233- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234 __*__ attributes. (Some already existed, e.g., __doc__ and
8235 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008236
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008237- Add -3 option to the interpreter to warn about features that are
8238 deprecated and will be changed/removed in Python 3.0.
8239
Georg Brandl2134e752007-05-21 20:34:16 +00008240- Patch #1686487: you can now pass any mapping after '**' in function
8241 calls.
8242
Collin Winter62903052007-05-18 23:11:24 +00008243- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008244 "except E as target:". This is to provide forwards compatibility
8245 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008246
Brett Cannon229cee22007-05-05 01:34:02 +00008247- Deprecate BaseException.message as per PEP 352.
8248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008250 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008251
Vinay Sajip8549ce32007-05-06 17:53:37 +00008252- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008253 setting a plain string, ie don't expand to single letter identifiers.
8254
Raymond Hettinger13936692007-04-11 18:40:58 +00008255- Request #1191699: Slices can now be pickled.
8256
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008257- Request #1193128: str.translate() now allows a None argument for
8258 translations that only remove characters without re-mapping the
8259 remaining characters.
8260
Georg Brandl5cb76c12007-03-21 09:00:39 +00008261- Patch #1682205: a TypeError while unpacking an iterable is no longer
8262 masked by a generic one with the message "unpack non-sequence".
8263
Neal Norwitzaa754b72007-03-21 06:39:48 +00008264- Remove unused file Python/fmod.c.
8265
Guido van Rossum143b5642007-03-23 04:58:42 +00008266- Bug #1683368: The object.__init__() and object.__new__() methods are
8267 now stricter in rejecting excess arguments. The only time when
8268 either allows excess arguments is when it is not overridden and the
8269 other one is. For backwards compatibility, when both are
8270 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008271 warning later). Also, type.__init__() insists on the same signature
8272 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8275 object to complex using its __complex__() method before falling back
8276 to the __float__() method. Therefore, the functions in the cmath
8277 module now can operate on objects that define a __complex__()
8278 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Patch #1623563: allow __class__ assignment for classes with
8281 __slots__. The old and the new class are still required to have the
8282 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008283

8288 ``object.__reduce_ex__()`` is called with an object that is faking
8289 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008290
Georg Brandl3ee81df2008-05-17 18:14:43 +00008291- Patch #1680015: Don't modify __slots__ tuple if it contains an

8295
Georg Brandl7b9c5552007-03-12 14:30:05 +00008296- Bug #1678647: write a newline after printing an exception in any
8297 case, even when converting the value to a string failed.
8298
Georg Brandl871f1bc2007-03-12 13:17:36 +00008299- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300 its argument, if it exists. If not, it will work like before. This
8301 allows customizing the output of dir() in the presence of a
8302 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Patch #1491866: change the complex() constructor to allow
8311 parthensized forms. This means complex(repr(x)) now works instead of
8312 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008313
Georg Brandlaa2321b2007-03-07 00:40:28 +00008314- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315 makes the filenames the warning module prints much more sensible
8316 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008317
Georg Brandl49aafc92007-03-07 00:34:46 +00008318- Variant of patch #697613: don't exit the interpreter on a SystemExit
8319 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320 variable is given, but break into the interactive interpreter just
8321 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008329- Patch #1674228: when assigning a slice (old-style), check for the
8330 sq_ass_slice instead of the sq_slice slot.
8331
Georg Brandl3ee81df2008-05-17 18:14:43 +00008332- When printing an unraisable error, don't print exceptions. before
8333 the name. This duplicates the behavior whening normally printing
8334 exceptions.

8961 -- the failure just occurred later, with a more cumbersome
8962 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00009173- ctypes callback functions only support 'fundamental' data types as
9174 result type. Raise an error when something else is used. This is a
9175 partial fix for Bug #1574584.
9176
Georg Brandl3ee81df2008-05-17 18:14:43 +00009177- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009233- The implementation of UnicodeError objects has been simplified
9234 (start and end attributes are now stored directly as Py_ssize_t
9235 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9238 with RFC 3207 and forgets any knowledge obtained from the server not
9239 obtained from the TLS negotiation itself. Patch contributed by Bill
9240 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009241
Georg Brandl3ee81df2008-05-17 18:14:43 +00009242- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009243 that the SMTP.starttls() caller no longer needs to call ehlo()
9244 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245 does not claim to support starttls. Adds the
9246 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9247 Fenner.

9285
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00009289- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009290 works as expected. ``mmap.find`` also takes an optional ``end``

9316 contents before adding elements from the iterable. This fix brings
9317 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009318
Georg Brandl3ee81df2008-05-17 18:14:43 +00009319- Added wide char functions to msvcrt module: getwch, getwche, putwch

9327 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9328 silently miscode subclasses of those types. Now, it raises a
9329 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009330

Georg Brandl3ee81df2008-05-17 18:14:43 +00009345 time so that opening a database previously created with the DB_DUP
9346 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9347 opens. Specifically: dictionary assignment to a DB object will
9348 replace all values for a given key when the database allows
9349 duplicate values. DB users should use DB.put(k, v) when they want
9350 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009351

9357 characters with ASCII value less than 32. Also, it correctly quotes
9358 dots only if they occur on a single line, as opposed to the previous
9359 behavior of quoting dots if they are the second character of any
9360 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009361

9688-----
9689
Georg Brandl3ee81df2008-05-17 18:14:43 +00009690- Unified naming convention for free lists and their limits. All free
9691 lists in Object/ are named ``free_list``, the counter ``numfree``
9692 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9693 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009694
Georg Brandl3ee81df2008-05-17 18:14:43 +00009695- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9696 to ``PyTuple_SetItem``, it can be used to populate a brand new
9697 frozenset; but it does not steal a reference to the added item.

9706
9707- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9708 ``PyFloat_GetInfo()`` to the float API.
9709
Georg Brandl3ee81df2008-05-17 18:14:43 +00009710- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9711 of w# format code incorrectly truncated the length to an int, even
9712 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9713 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009714
Georg Brandl3ee81df2008-05-17 18:14:43 +00009715- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9733- Fix some leftovers from the conversion from int to Py_ssize_t
9734 (relevant to strings and sequences of more than 2**31 items).
9735
9736- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9737 outside of pystate.c and should not be necessary.
9738
Georg Brandl3ee81df2008-05-17 18:14:43 +00009739- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9740 absolute imports. In earlier versions they might have used relative
9741 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009742
Georg Brandl3ee81df2008-05-17 18:14:43 +00009743- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9744 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009745
Georg Brandl3ee81df2008-05-17 18:14:43 +00009746- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009752- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9753 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9754 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9755 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009756

Georg Brandl3ee81df2008-05-17 18:14:43 +00009769- Removed the macfs module. It had been deprecated since Python 2.5.
9770 This lead to the deprecation of macostools.touched() as it relied
9771 solely on macfs and was a no-op under OS X.
