14
Antoine Pitrou16166452011-07-12 22:04:20 +020015- Issue #12149: Update the method cache after a type's dictionnary gets
16 cleared by the garbage collector. This fixes a segfault when an instance
17 and its type get caught in a reference cycle, and the instance's
18 deallocator calls one of the methods on the type (e.g. when subclassing
19 IOBase). Diagnosis and patch by Davide Rizzo.
20
Victor Stinnerba8b3a22011-07-08 02:07:45 +020021- Issue #12501: Adjust callable() warning: callable() is only not supported in
22 Python 3.1. callable() is again supported in Python 3.2.
23
Victor Stinner59729ff2011-07-05 11:28:19 +020024- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and

Victor Stinner08563d92011-05-30 23:44:13 +020028 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
29 raw_input() interrupted by CTRL+c.

Antoine Pitrou304f0f92011-07-15 21:22:50 +020036- Issue #11603: Fix a crash when __str__ is rebound as __repr__. Patch by
37 Andreas Stührk.
38
Charles-François Natali26591402011-07-14 19:49:02 +020039- Issue #12502: asyncore: fix polling loop with AF_UNIX sockets.
40
Victor Stinnerbf547fd2011-07-13 21:47:31 +020041- Issue #4376: ctypes now supports nested structures in a endian different than
42 the parent structure. Patch by Vlad Riscutia.

51 the garbage collector while the Heap lock is held.
52
Ned Deily87e82bb2011-06-28 19:52:59 -070053- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
54 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
55 interpreter process. This could cause failures in non-Distutils subprocesses
56 and was unreliable since tests or user programs could modify the interpreter
57 environment after Distutils set it. Instead, have Distutils set the the
58 deployment target only in the environment of each build subprocess. It is
59 still possible to globally override the default by setting
60 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
61 greater or equal to the default value, the value with which the interpreter
62 was built.
63
Raymond Hettinger2c316a32011-06-25 17:14:53 +020064- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

68 Kitada.
69
R David Murrayf1138bb2011-06-17 22:23:04 -040070- Issue #11700: mailbox proxy object close methods can now be called multiple
71 times without error, and _ProxyFile now closes the wrapped file.
72
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020073- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
74 connection if its getresponse() method fails with a socket error. Patch
75 written by Ezio Melotti.
76
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050077- Issue #9284: Allow inspect.findsource() to find the source of doctest
78 functions.
79
R David Murray873c5832011-06-09 16:01:09 -040080- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
81

83 instead of os.stat.
84
Mark Dickinsona493ca32011-06-04 18:24:15 +010085- Issue #12080: Fix a performance issue in Decimal._power_exact that caused
86 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
87

89
Raymond Hettinger19b851d2011-06-01 18:21:42 -070090- sys.setcheckinterval() now updates the current ticker count as well as updating
91 the check interval, so if the user decreases the check interval, the ticker
92 doesn't have to wind down to zero from the old starting point before the new
93 interval takes effect. And if the user increases the interval, it makes sure
94 the new limit takes effect right away rather have an early task switch before
95 recognizing the new interval.
96
Victor Stinner776e69b2011-06-01 01:03:00 +020097- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
98 constructor has failed, e.g. because of an undeclared keyword argument. Patch
99 written by Oleg Oshmyan.

119 an overzealous DNS service (e.g. OpenDNS) redirects to a placeholder
120 Web site.
121
Antoine Pitroua4d58d22011-07-08 19:14:19 +0200122- Avoid failing in test_urllibnet.test_bad_address when some overzealous

915 handles non-blocking readinto() returning None correctly.
916
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000917- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
918 SSLSocket.sendto() to match the corresponding socket methods. Also,
919 fix various SSLSocket methods to raise socket.error rather than an
920 unhelpful TypeError when called on an unconnected socket. Original patch
921 by Andrew Bennetts.

930
Raymond Hettinger20397532010-09-12 02:11:45 +0000931- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
932 This prevents user-created self-referencing ordered dictionaries from
933 becoming permanently uncollectable GC garbage. The downside is that
934 removing __del__ means that the internal doubly-linked list has to wait for
935 GC collection rather than freeing memory immediately when the refcnt drops
936 to zero.
937

944 to fetch the original errno, or to filter timeout errors. Now the
945 original error is re-raised.

985 ignored by the buffered IO layer anymore.
986
Benjamin Peterson52c36052010-08-21 03:03:22 +0000987- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

989
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000990- Issue #9626: the view methods for collections.OrderedDict() were returning

1005 patch by Jason V. Miller.

Georg Brandlfee0f442010-05-22 21:26:21 +00001755- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001756 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1757 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1758 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1779-----------------
1780
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001781- Issue #7301: Add environment variable $PYTHONWARNINGS.
1782
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001783- Issue #8329: Don't return the same lists from select.select when no fds are
1784 changed.
1785
Georg Brandlfee0f442010-05-22 21:26:21 +00001786- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001787 on 64-bit machines. The shift count for either left or right shift is
1788 permitted to be up to sys.maxsize.
1789
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001790- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001792- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001793
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001794- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1795
Georg Brandlfee0f442010-05-22 21:26:21 +00001796- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1797 with a non-empty format string. This is an effort to future-proof user
1798 code. If a derived class does not currently implement __format__ but later
1799 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001800 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001801 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001802
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001803- Issue #8268: Old-style classes (not just instances) now support weak

1815
Victor Stinner66644262010-03-10 22:30:19 +00001816- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001817 (SIGINT). If an error occurs while importing the site module, the error is
1818 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001819 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001832- Issue #8310: Allow dis to examine new style classes.
1833
Georg Brandlfee0f442010-05-22 21:26:21 +00001834- Issue #8257: The Decimal construct now accepts a float instance directly,
1835 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001836
1837 >>> Decimal(1.1)
1838 Decimal('1.100000000000000088817841970012523233890533447265625')
1839
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001840- collections.Counter() now supports a subtract() method.
1841
Georg Brandlfee0f442010-05-22 21:26:21 +00001842- The functools module now has a total_ordering() class decorator to simplify
1843 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001844
Georg Brandlfee0f442010-05-22 21:26:21 +00001845- The functools module also adds cmp_to_key() as a tool to transition old-style
1846 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001847
Georg Brandlfee0f442010-05-22 21:26:21 +00001848- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1849 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001850
Georg Brandlfee0f442010-05-22 21:26:21 +00001851- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1852 InvalidOperation instead of returning False. (Comparisons involving a quiet
1853 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1854 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001855
Georg Brandlfee0f442010-05-22 21:26:21 +00001856- Issue #2531: Comparison operations between floats and Decimal instances now
1857 return a result based on the numeric values of the operands; previously they
1858 returned an arbitrary result based on the relative ordering of id(float) and
1859 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001860
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001861- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001862 argument `-` which tells it to read files to compile from stdin. Each line is
1863 read on demand and the named file is compiled immediately. (Original patch by
1864 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001865
Georg Brandlfee0f442010-05-22 21:26:21 +00001866- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1867 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001869- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1870 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001871 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001872
Georg Brandlfee0f442010-05-22 21:26:21 +00001873- Comparisons using one of <, <=, >, >= between a complex instance and a
1874 Fractions instance now raise TypeError instead of returning True/False. This
1875 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1876 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001877
Michael Foorde6410c52010-03-29 20:04:23 +00001878- Addition of ``WeakSet`` to the ``weakref`` module.

1886
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001887- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001888 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1889 silenced.

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001891- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1892 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001932 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1933 log file to compute the next rollover time. If the log file does not exist,
1934 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001975- Issue #8300: When passing a non-integer argument to struct.pack with any
1976 integer format code, struct.pack first attempts to convert the non-integer

1981 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1982 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001983 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1984 inconsistent: __int__ was used for some integer codes but not for others, and
1985 the set of integer codes for which it was used differed between native packing
1986 and standard packing.)

2218 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002219 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00002238- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2239 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2240 returning NULL. The macro now returns a statically allocated empty string
2241 instead.

2251 strings,
2252 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2253 numeric strings corresponding to subnormal values,
2254 (3) a memory leak for some values large enough to cause overflow, and
2255 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002286- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002287 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002288 Also, raise ValueError rather than TypeError when an unknown TIPC address
2289 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002293- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002294 file position when calling `truncate()`. It would previously change the file
2295 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002296 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2297
Georg Brandlba83f822010-03-14 09:50:54 +00002298- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2299 class used to represent files stored inside an archive. The new
2300 implementation is significantly faster and can be wrapped in a
2301 ``io.BufferedReader`` object for more speedups. It also solves an issue
2302 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2303 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002312
Georg Brandlba83f822010-03-14 09:50:54 +00002313- Issue #7748: Since unicode values are supported for some metadata options in
2314 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2315 encoded string for them. This ensures that the upload and register commands
2316 send the correct values to PyPI without any error.

2404 and many unicode/str methods.

2428
Georg Brandlba83f822010-03-14 09:50:54 +00002429 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002587- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2588 decimal string that's guaranteed to round back to x under correct rounding
2589 (with round-half-to-even rounding mode). Previously it gave a string based on
2590 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2591 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2592 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002593
Georg Brandlba83f822010-03-14 09:50:54 +00002594- Issue #7117: On almost all platforms: float-to-string and string-to-float
2595 conversions within Python are now correctly rounded. Places these conversions
2596 occur include: str for floats and complex numbers; the float and complex
2597 constructors; old-style and new-style numeric formatting; serialization and
2598 deserialization of floats and complex numbers using marshal, pickle and json;
2599 parsing of float and imaginary literals in Python code; Decimal-to-float
2600 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002601
Georg Brandlba83f822010-03-14 09:50:54 +00002602 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2603 providing correctly-rounded strtod and dtoa C functions. This code is
2604 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2605 the C compiler. There may be a small number of platforms on which correct
2606 operation of this code cannot be guaranteed, so the code is not used: notably,
2607 this applies to platforms where the C double format is not IEEE 754 binary64,
2608 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2609 and Python's configure script is unable to determine how to change the FPU
2610 precision. On these platforms conversions use the platform strtod and dtoa,
2611 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002612
Georg Brandlba83f822010-03-14 09:50:54 +00002613- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2614 uses the correctly-rounded string <-> float conversions described above (when
2615 available), and so produces correctly rounded results that will display nicely
2616 under the float repr. There are two related small changes: (1) round now
2617 accepts any class with an ``__index__()`` method for its second argument (but
2618 no longer accepts floats for the second argument), and (2) an excessively
2619 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2620 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002767- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2768 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2769 but with at least one decimal point and with a default precision
2770 of 12. Previously, the behavior the same but with a default precision of 6.
2771 This more closely matches ``str()``, and reduces surprises when adding
2772 alignment flags to the empty presentation type. This also affects the new
2773 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002913- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2914 existing .py counterpart, override the co_filename attributes of all code

2970
Georg Brandlba83f822010-03-14 09:50:54 +00002971- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2972 file objects with closefd=False. The file descriptor is still kept open but
2973 the file object behaves like a closed file. The ``FileIO`` object also got a

2993
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002994- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002997- On windows, ``os.chdir()`` given unicode was not working if

2999 this code path is really executed because I cannot move to such directory on
3000 win2k)

3003 element is temporarily replaced with an equivalent frozenset. But the
3004 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00003025- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3026 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3027 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3028 of using the replace error handler in PyUnicode_DecodeUTF8().
3029
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003030- Issue #3739: The unicode-internal encoder now reports the number of characters

3032
Georg Brandlba83f822010-03-14 09:50:54 +00003033- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3035 gives improved memory leak detection when running under Valgrind, while taking
3036 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004259 leak-chasing test runs give sensible results. The previous method of reaping
4260 threads could return successfully while some Thread objects were still
4261 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004278- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4279 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004280 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4281 the tests if DISPLAY is defined but can't be used.

4287 import both normal and optimised versions of modules. test_heapq and
4288 test_warnings have been adjusted to use it, tests for other modules with both
4289 C and Python implementations in the stdlib can be adjusted to use it over
4290 time.

4299 should cause a test to be skipped are now done using import_module from test
4300 support, which does the conversion.

4402
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004403- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4404 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4405 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4406 ``printf`` function, whereas PyString_FromFormat has an independent
4407 implementation and uses "%zd" on all platforms for size_t values.
4408 This makes a difference on win64, where ``printf`` needs "%Id" to display
4409 64bit values.

4415 object; previously an int would be returned for small values. the __long__
4416 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004426 was correctly parsed but parsing of subsequent arguments failed.
4427
Vinay Sajip35e3b032008-09-01 14:33:59 +00004428- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004429 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4430 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4431 when given a tuple of classes as second argument, were looking up
4432 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4433 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004572What's New in Python 2.6 beta 3?
4573================================
4574
Barry Warsaw07a4a382008-08-21 01:15:08 +00004575*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004576
4577Core and Builtins
4578-----------------
4579
Guido van Rossumf8402962008-08-20 15:01:50 +00004580- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4581 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4582 extensions do not automatically benefit from the class attribute
4583 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4584 to their tp_flags field if they care. This is a backwards
4585 compatibility feature; in 3.0, all types will use the cache by
4586 default.
4587
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004588- Keyword arguments can now follow starred arguments. (``f(a, *args,
4589 keyword=23)`` is now valid syntax.)
4590
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004591- ctypes function pointers that are COM methods have a boolean True
4592 value again.
4593
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004594- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4595 by denying s# to parse objects that have a releasebuffer procedure,
4596 and introducing s*.
4597
Georg Brandl1e13ea92008-08-11 09:07:59 +00004598- Issue #3537: Fix an assertion failure when an empty but presized dict
4599 object was stored in the freelist.
4600
Mark Dickinsonb6467572008-08-04 21:30:09 +00004601- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4602 ValueError consistently across platforms.
4603
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004604- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4605 (64bit Unix, for example), unichr() would truncate its argument and return
4606 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4607
Neal Norwitze7d8be82008-07-31 17:17:14 +00004608- Apply security patches from Apple.
4609
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004610- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4611 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4612
Antoine Pitrou92f82162008-07-25 22:22:08 +00004613- Issue #1819: function calls with several named parameters are now on
4614 average 35% faster (as measured by pybench).
4615
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004616- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4617 the python debugger steps into a class statement: the free variables (local
4618 variables defined in an outer scope) would be deleted from the outer scope.
4619
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004620- Issue #2620: Overflow checking when allocating or reallocating memory
4621 was not always being done properly in some python types and extension
4622 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4623 all been updated to perform better checks and places in the code that
4624 would previously leak memory on the error path when such an allocation
4625 failed have been fixed.

4629
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004630- Issue #3612: Added some missing basic types in ctypes.wintypes.
4631
Benjamin Petersone977ad42008-08-20 01:42:01 +00004632- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4633 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4634
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004635- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4636 version reported by these tools does not necessarily follow the python
4637 version numbering scheme, so the module is less strict when parsing it.
4638
Nick Coghlanf70385a2008-08-18 12:42:46 +00004639- Issue #2235: Added Py3k warnings for types which will become unhashable
4640 under the stricter __hash__ inheritance rules in 3.0. Several types
4641 which did not meet the rules for hash invariants and were already
4642 unhashable in 3.0 have now been explicitly flagged as unhashable in
4643 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4644 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4645
Brett Cannon88f801d2008-08-18 00:46:22 +00004646- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4647 imported into the module but exposed as part of the module's API.
4648
Brett Cannon7b96f072008-08-18 00:41:11 +00004649- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4650
Brett Cannon46225e72008-08-18 00:36:52 +00004651- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4652
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004653- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4654
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004655- Issue #3575: Incremental decoder's decode function now takes bytearray
4656 by using 's*' instead of 't#'.
4657
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004658- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004659 fails unicode conversion on 2nd parameter. (windows only)
4660
Georg Brandl222e2082010-08-01 22:27:39 +00004661- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004662 in a redirect.
4663
Brett Cannonabe423e2008-08-16 21:47:07 +00004664- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004665 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004666
Facundo Batistaeb90b782008-08-16 14:44:07 +00004667- Issue #2776: fixed small issue when handling an URL with double slash
4668 after a 302 response in the case of not going through a proxy.
4669
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004670- Issue #2676: in the email package, content-type parsing was hanging on
4671 pathological input because of quadratic or exponential behaviour of a
4672 regular expression.
4673
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004674- Issue #3476: binary buffered reading through the new "io" library is now
4675 thread-safe.
4676
Brett Cannonbf3157b2008-08-14 05:00:03 +00004677- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4678 since mimetools itself is deprecated. Because modules are cached, all
4679 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4680
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004681- Issue #3134: shutil referenced undefined WindowsError symbol.
4682
Robert Schuppenies14646332008-08-10 11:01:53 +00004683- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4684 menu entries were not deleted.
4685
Brett Cannon83e81842008-08-09 23:30:55 +00004686- Copied the implementation of reduce() to _functools.reduce() to have a
4687 version that did not raise a DeprecationWarning under -3.
4688
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004689- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4690 a MemoryError rather than silently stop the iteration.
4691
Guido van Rossum59ce9012008-08-09 14:55:34 +00004692- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4693 to _sre.compile() will now be rejected. This should not affect anybody
4694 since the re.compile() function never generates invalid re-bytecode.
4695
Skip Montanaroa032bf42008-08-08 22:52:51 +00004696- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4697 upon first access it can be automatically initialized from the csv file if
4698 it wasn't initialized during instantiation.
4699
Brett Cannon3aa2a492008-08-06 22:28:09 +00004700- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4701 the reload() built-in has been removed.
4702
Brett Cannon7e30b672008-08-04 21:52:25 +00004703- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004704 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00004710
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004711- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4712 raised an AttributeError.
4713
Benjamin Peterson01a24322008-07-28 23:35:27 +00004714- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004715 asking for a specific length. This problem only affected files opened
4716 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004717
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004718- Issue #3449: Update decimal module to use most recent specification
4719 (v. 1.68) and tests (v. 2.58) from IBM.
4720
Georg Brandl222e2082010-08-01 22:27:39 +00004721- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004722

4725
Georg Brandlf9efabb2008-07-23 15:16:45 +00004726- Deprecate the "ast" parser function aliases.
4727
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004728- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4729
4730- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4731 invalid arguments.
4732
4733- Issue #3302: Fix several crashes when calling locale's gettext functions
4734 with None arguments.
4735
4736- Issue #3389: Allow resolving dotted names for handlers in logging
4737 configuration files.
4738

4740
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004741- Issue #3394: zipfile.writestr sets external attributes when passed a
4742 file name rather than a ZipInfo instance, so files are extracted with
4743 mode 0600 rather than 000 under Unix.
4744
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004745- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4746 argument in python 2.5, this broke code that subclassed Popen to include its
4747 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004757- Issue #2235: the C API function PyObject_HashNotImplemented and its
4758 interaction with the tp_hash slot (added in 2.6b2) are now documented
4759
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004760- Issue #643841: The language reference now provides more detailed
4761 coverage of the lookup process for special methods. The disclaimers
4762 regarding lack of coverage of new-style classes have also been
4763 removed, since the coverage is now fairly reasonable.

4772-----------------
4773
Georg Brandl3e483f62008-07-16 22:57:41 +00004774- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4775 its methods now allow for items objects that can be converted to
4776 an integer using operator.index().
4777
Mark Dickinson64b7e502008-07-16 09:40:03 +00004778- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4779 produced a ValueError instead of giving the correct float.
4780
Eric Smitha5fa5a22008-07-16 00:11:49 +00004781- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4782 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4783
Mark Dickinson7103aa42008-07-15 19:08:33 +00004784- Issue #3008: the float type has a new instance method 'float.hex'
4785 and a new class method 'float.fromhex' to convert floating-point
4786 numbers to and from hexadecimal strings, respectively.
4787
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004788- Issue #2235: __hash__ is once again inherited by default. To allow
4789 collections.Hashable to remain meaningful in the presence of the
4790 default hash implementation (object.__hash__), it is now possible
4791 to explicit block inheritance of hash by setting __hash__=None at
4792 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4793 level.
4794
Nick Coghlanb028f502008-07-13 14:52:36 +00004795- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4796 the parent module cannot be found while performing an absolute import.
4797 This means that an incorrectly defined __package__ attribute will
4798 now only prevent relative imports in that module rather than causing
4799 all imports from that module to fail.
4800
Nick Coghlan14ff9942008-07-08 14:21:42 +00004801- Issue #2517: Allow unicode messages in Exceptions again by correctly
4802 bypassing the instance dictionary when looking up __unicode__ on
4803 new-style classes.
4804
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004805- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4806 set to a custom object whose write() method happens to install
4807 another file in sys.stdout.

4811 another thread's dictionary.
4812
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004813- Issue #3004: Minor change to slice.indices(): the start and stop
4814 arguments are now treated identically, making the behaviour easier
4815 to describe and understand. For example, slice(None, -10,
4816 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4817 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4818 10, -1).
4819
Georg Brandl278fc502008-07-19 12:46:12 +00004820- Issue #3219: Calling a function with repeated keyword arguments,
4821 f(a=2, a=23), would not cause a syntax error. This was a regression
4822 from 2.4 caused by the switch to the new compiler.

5271 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005272 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005273
5274 This is controlled by the configure argument ``--with-universal-archs``:
5275
5276 - ``--with-universal-archs=all``: install 4-way universal
5277
5278 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5279
5280 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5281
5282 This option should be used in combination with ``--enable-universalsdk=``.
5283
5284 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5321 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005322
Christian Heimese74c8f22008-04-19 02:23:57 +00005323- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5324

Georg Brandl3ee81df2008-05-17 18:14:43 +00005334- Issue #1631171: Re-implement the 'warnings' module in C (the
5335 original Python code has been kept as backup). This will allow for
5336 using the 'warning's machinery in such places as the parser where
5337 use of pure Python code is not possible. Both the ``showarning()``
5338 and ``formatwarning()`` gain an optional 'line' argument which is
5339 not called by default for backwards-compatibility reasons. Setting
5340 ``warnings.showwarning()`` to an implementation that lacks support
5341 for the ``line`` argument will raise a DeprecationWarning.

5365
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005366- The getpass module has been improved on Unix. It now uses /dev/tty
5367 by default and uses stderr instead of stdout. A GetPassWarning is
5368 issued when input echo cannot be controlled.

Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00005387- Issue #815646: Individual file objects may now be used from multiple
5388 threads at once without fear of crashing the Python interpreter. If
5389 file.close() is called while an object is in use by another thread
5390 an IOError exception will be raised and the file will not be closed.

5394 Modules/_ctypes/libffi/configure.ac.
5395
Georg Brandl3ee81df2008-05-17 18:14:43 +00005396- Issue #2385: distutils.core.run_script() makes __file__ available,
5397 so the controlled environment will more closely mirror the typical
5398 script environment. This supports setup.py scripts that refer to
5399 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005404- Issue #2550: The approach used by client/server code for obtaining
5405 ports to listen on in network-oriented tests has been refined in an
5406 effort to facilitate running multiple instances of the entire
5407 regression test suite in parallel without issue.
5408 test_support.bind_port() has been fixed such that it will always
5409 return a unique port -- which wasn't always the case with the
5410 previous implementation, especially if socket options had been set
5411 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5412 new implementation of bind_port() will actually raise an exception
5413 if it is passed an AF_INET/SOCK_STREAM socket with either the
5414 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5415 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5416 the socket it's been passed. This currently only applies to
5417 Windows. This option prevents any other sockets from binding to the
5418 host/port we've bound to, thus removing the possibility of the
5419 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5420 when a second SOCK_STREAM socket binds and accepts to a host/port
5421 that's already been bound by another socket. The optional preferred
5422 port parameter to bind_port() has been removed. Under no
5423 circumstances should tests be hard coding ports!
5424
5425 test_support.find_unused_port() has also been introduced, which will
5426 pass a temporary socket object to bind_port() in order to obtain an
5427 unused port. The temporary socket object is then closed and
5428 deleted, and the port is returned. This method should only be used
5429 for obtaining an unused port in order to pass to an external program
5430 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5431 a parameter to a server-oriented class that doesn't give you direct
5432 access to the underlying socket used.
5433
5434 Finally, test_support.HOST has been introduced, which should be used
5435 for the host argument of any relevant socket calls (i.e. bind and
5436 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005437
5438 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005439 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005440 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5441 test_asynchat and test_socket_ssl.
5442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443 It is now possible for multiple instances of the regression test
5444 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00005648- The bundled libffi copy is now in sync with the recently released
5649 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005650 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5651 files are used. On all linux systems the --with-system-ffi
5652 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00005723- Added the future_builtins module, which contains hex() and oct().
5724 These are the PEP 3127 version of these functions, designed to be
5725 compatible with the hex() and oct() builtins from Python 3.0. They
5726 differ slightly in their output formats from the existing, unchanged
5727 Python 2.6 builtins. The expected usage of the future_builtins
5728 module is:
5729 from future_builtins import hex, oct
5730
Eric Smith7ef40bf2008-02-20 23:34:22 +00005731- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5732 exponents for exponents with absolute value < 100. Follows C99
5733 standard. This is a change on Windows, which would use 3 digits.
5734 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5735 so that any alterations it does to the resulting string will be
5736 available in stringlib/formatter.h (for float.__format__).
5737
Eric Smith5a3c1352008-02-19 13:21:56 +00005738- Implemented PEP 3101, Advanced String Formatting. This adds a new
5739 builtin format(); a format() method for str and unicode; a
5740 __format__() method to object, str, unicode, int, long, float, and
5741 datetime; the class string.Formatter; and the C API
5742 PyObject_Format().
5743
Georg Brandl3ee81df2008-05-17 18:14:43 +00005744- Fixed several potential crashes, all caused by specially crafted
5745 __del__ methods exploiting objects in temporarily inconsistent
5746 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005747
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005748- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749 prevent a possible crash: an Abstract Base Class would try to access
5750 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005755- Clear all free lists during a gc.collect() of the highest generation
5756 in order to allow pymalloc to free more arenas. Python may give back
5757 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005758
Georg Brandl3ee81df2008-05-17 18:14:43 +00005759- Issue #2045: Fix an infinite recursion triggered when printing a
5760 subclass of collections.defaultdict, if its default_factory is set
5761 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005762
Christian Heimesf75dbef2008-02-08 00:11:31 +00005763- Fixed a minor memory leak in dictobject.c. The content of the free
5764 list was not freed on interpreter shutdown.
5765
Georg Brandl21e99f42010-03-07 15:23:59 +00005766- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005767 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5770 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005771 to compact the internal free lists of pre-allocted ints and floats.
5772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5774 calls. Python expected the return type int but the fork familie
5775 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005776

Georg Brandl3ee81df2008-05-17 18:14:43 +00005789- Patch #1473257: generator objects gain a gi_code attribute. This is
5790 the same object as the func_code attribute of the function that
5791 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005792
Georg Brandl3ee81df2008-05-17 18:14:43 +00005793- Issue #1920: "while 0" statements were completely removed by the
5794 compiler, even in the presence of an "else" clause, which is
5795 supposed to be run when the condition is false. Now the compiler
5796 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005797
Guido van Rossumeead05f2008-01-24 18:21:02 +00005798- A few crashers fixed: weakref_in_del.py (issue #1377858);
5799 loosing_dict_ref.py (issue #1303614, test67.py);
5800 borrowed_ref_[34].py (not in tracker).
5801
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005802- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005803 suppressed while an extension is loaded by calling SetErrorMode in

5805
Georg Brandl3ee81df2008-05-17 18:14:43 +00005806- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005807 several extension methods and modules do not work without unicode
5808 support.
5809
Georg Brandl26543b12008-01-21 18:36:51 +00005810- Issue #1882: when compiling code from a string, encoding cookies in the
5811 second line of code were not always recognized correctly.
5812
Georg Brandl14404b62008-01-19 19:27:05 +00005813- Issue #1679: "0x" was taken as a valid integer literal.
5814
Georg Brandl6caad7d2008-01-26 14:19:22 +00005815- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005816 added.
5817
Christian Heimesc94e2b52008-01-14 04:13:37 +00005818- sys.float_info / PyFloat_GetInfo: The floating point information
5819 object was converted from a dict to a specialized structseq object.
5820
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- Patch #1816: Added sys.flags structseq. It exposes the status of
5822 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005823
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824- Objects/structseq.c: Implemented new structseq representation. The

5892 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005893
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005894- sets and frozensets now have an isdisjoint() method.

5899
Georg Brandl21e99f42010-03-07 15:23:59 +00005900- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005901 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5902 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005903
Georg Brandl3ee81df2008-05-17 18:14:43 +00005904- Issue #1686386: Tuple's tp_repr did not take into account the
5905 possibility of having a self-referential tuple, which is possible
5906 from C code. Nor did object's tp_str consider that a type's tp_str
5907 could do something that could lead to an inifinite recursion.
5908 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5909 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005910
Georg Brandl3ee81df2008-05-17 18:14:43 +00005911- Issue #1164: It was possible to trigger deadlock when using the
5912 'print' statement to write to a file since the GIL was not released
5913 as needed. Now PyObject_Print() does the right thing along with
5914 various tp_print implementations of the built-in types and those in
5915 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005916
Georg Brandl3ee81df2008-05-17 18:14:43 +00005917- Issue #1147: Exceptions were directly allowing string exceptions in
5918 their throw() method even though string exceptions no longer
5919 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00005923
Brett Cannon1e534b52007-09-07 04:18:30 +00005924- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925 PyObject_Call() never calling back out to Python code to trigger
5926 recursion depth updates/checks. Required the creation of a static
5927 RuntimeError instance in case normalizing an exception put the
5928 recursion check value past its limit. Fixes crashers
5929 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005930

Neal Norwitz0ac60192007-05-27 04:08:54 +00005944- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005945 __*__ attributes. (Some already existed, e.g., __doc__ and
5946 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005947
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005948- Add -3 option to the interpreter to warn about features that are
5949 deprecated and will be changed/removed in Python 3.0.
5950
Georg Brandl2134e752007-05-21 20:34:16 +00005951- Patch #1686487: you can now pass any mapping after '**' in function
5952 calls.
5953
Collin Winter62903052007-05-18 23:11:24 +00005954- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005955 "except E as target:". This is to provide forwards compatibility
5956 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005957
Brett Cannon229cee22007-05-05 01:34:02 +00005958- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005963- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005964 setting a plain string, ie don't expand to single letter identifiers.
5965
Raymond Hettinger13936692007-04-11 18:40:58 +00005966- Request #1191699: Slices can now be pickled.
5967
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005968- Request #1193128: str.translate() now allows a None argument for
5969 translations that only remove characters without re-mapping the
5970 remaining characters.
5971
Georg Brandl5cb76c12007-03-21 09:00:39 +00005972- Patch #1682205: a TypeError while unpacking an iterable is no longer

5976
Guido van Rossum143b5642007-03-23 04:58:42 +00005977- Bug #1683368: The object.__init__() and object.__new__() methods are
5978 now stricter in rejecting excess arguments. The only time when
5979 either allows excess arguments is when it is not overridden and the
5980 other one is. For backwards compatibility, when both are
5981 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005982 warning later). Also, type.__init__() insists on the same signature
5983 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005984
Georg Brandl3ee81df2008-05-17 18:14:43 +00005985- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5986 object to complex using its __complex__() method before falling back
5987 to the __float__() method. Therefore, the functions in the cmath
5988 module now can operate on objects that define a __complex__()
5989 method.

6006
Georg Brandl7b9c5552007-03-12 14:30:05 +00006007- Bug #1678647: write a newline after printing an exception in any
6008 case, even when converting the value to a string failed.
6009
Georg Brandl871f1bc2007-03-12 13:17:36 +00006010- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011 its argument, if it exists. If not, it will work like before. This
6012 allows customizing the output of dir() in the presence of a
6013 __getattr__().

6022 parthensized forms. This means complex(repr(x)) now works instead of
6023 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006024
Georg Brandlaa2321b2007-03-07 00:40:28 +00006025- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026 makes the filenames the warning module prints much more sensible
6027 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006028

Georg Brandl0fca97a2007-03-05 22:28:08 +00006040- Patch #1674228: when assigning a slice (old-style), check for the
6041 sq_ass_slice instead of the sq_slice slot.
6042
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- When printing an unraisable error, don't print exceptions. before
6044 the name. This duplicates the behavior whening normally printing
6045 exceptions.

6673 -- the failure just occurred later, with a more cumbersome
6674 exception.

6887 partial fix for Bug #1574584.
6888
Georg Brandl3ee81df2008-05-17 18:14:43 +00006889- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006955- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6956 with RFC 3207 and forgets any knowledge obtained from the server not
6957 obtained from the TLS negotiation itself. Patch contributed by Bill
6958 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006961 that the SMTP.starttls() caller no longer needs to call ehlo()
6962 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006963 does not claim to support starttls. Adds the
6964 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6965 Fenner.

7003
Georg Brandl3ee81df2008-05-17 18:14:43 +00007004- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00007007- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00007008 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007019- itertools.chain() now has an alternate constructor,

7034 contents before adding elements from the iterable. This fix brings
7035 the behavior into line with that for list.__init__().

7045 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7046 silently miscode subclasses of those types. Now, it raises a
7047 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007048

Georg Brandl3ee81df2008-05-17 18:14:43 +00007063 time so that opening a database previously created with the DB_DUP
7064 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7065 opens. Specifically: dictionary assignment to a DB object will
7066 replace all values for a given key when the database allows
7067 duplicate values. DB users should use DB.put(k, v) when they want
7068 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007069

7075 characters with ASCII value less than 32. Also, it correctly quotes
7076 dots only if they occur on a single line, as opposed to the previous
7077 behavior of quoting dots if they are the second character of any
7078 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007079

7401-----
7402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Unified naming convention for free lists and their limits. All free
7404 lists in Object/ are named ``free_list``, the counter ``numfree``
7405 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7406 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7409 to ``PyTuple_SetItem``, it can be used to populate a brand new
7410 frozenset; but it does not steal a reference to the added item.

7422
Georg Brandl3ee81df2008-05-17 18:14:43 +00007423- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7424 of w# format code incorrectly truncated the length to an int, even
7425 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7426 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007427
Georg Brandl3ee81df2008-05-17 18:14:43 +00007428- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7446- Fix some leftovers from the conversion from int to Py_ssize_t
7447 (relevant to strings and sequences of more than 2**31 items).
7448
7449- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7450 outside of pystate.c and should not be necessary.
7451
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7453 absolute imports. In earlier versions they might have used relative
7454 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007455
Georg Brandl3ee81df2008-05-17 18:14:43 +00007456- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7457 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7467 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7468 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7469 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007470

Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Removed the macfs module. It had been deprecated since Python 2.5.
7485 This lead to the deprecation of macostools.touched() as it relied
7486 solely on macfs and was a no-op under OS X.
