82
Ned Deily87e82bb2011-06-28 19:52:59 -070083- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
84 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
85 interpreter process. This could cause failures in non-Distutils subprocesses
86 and was unreliable since tests or user programs could modify the interpreter
87 environment after Distutils set it. Instead, have Distutils set the the
88 deployment target only in the environment of each build subprocess. It is
89 still possible to globally override the default by setting
90 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
91 greater or equal to the default value, the value with which the interpreter
92 was built.
93
Raymond Hettinger2c316a32011-06-25 17:14:53 +020094- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

98 Kitada.
99
R David Murrayf1138bb2011-06-17 22:23:04 -0400100- Issue #11700: mailbox proxy object close methods can now be called multiple
101 times without error, and _ProxyFile now closes the wrapped file.
102
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200103- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
104 connection if its getresponse() method fails with a socket error. Patch
105 written by Ezio Melotti.
106
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500107- Issue #9284: Allow inspect.findsource() to find the source of doctest
108 functions.
109
R David Murray873c5832011-06-09 16:01:09 -0400110- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
111
Brian Curtincaea7e82011-06-08 19:29:53 -0500112- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes
113 instead of os.stat.
114
Mark Dickinsona493ca32011-06-04 18:24:15 +0100115- Issue #12080: Fix a performance issue in Decimal._power_exact that caused
116 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
117

119
Barry Warsawc5643282011-07-19 17:06:30 -0400120- sys.setcheckinterval() now updates the current ticker count as well as
121 updating the check interval, so if the user decreases the check interval,
122 the ticker doesn't have to wind down to zero from the old starting point
123 before the new interval takes effect. And if the user increases the
124 interval, it makes sure the new limit takes effect right away rather have an
125 early task switch before recognizing the new interval.

Victor Stinner776e69b2011-06-01 01:03:00 +0200127- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
128 constructor has failed, e.g. because of an undeclared keyword argument. Patch

978 This prevents user-created self-referencing ordered dictionaries from
979 becoming permanently uncollectable GC garbage. The downside is that
980 removing __del__ means that the internal doubly-linked list has to wait for
981 GC collection rather than freeing memory immediately when the refcnt drops
982 to zero.
983

1014 character years even if the message contains RFC822 two character years.
1015

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001048- Issue #9550: a BufferedReader could issue an additional read when the

1050 when the underlying raw IO channel was e.g. a socket. Report and original
1051 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001441- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1442 start byte and the continuation byte(s) are now considered invalid, instead
1443 of the number of bytes specified by the start byte.
1444 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1445 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1456 objects. (1) The comparison could incorrectly return True in some cases
1457 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1654 operation raises multiple signals and more than one of those signals is
1655 trapped, the specification determines the order in which the signals should be

1825-----------------
1826
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001827- Issue #7301: Add environment variable $PYTHONWARNINGS.
1828
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001829- Issue #8329: Don't return the same lists from select.select when no fds are
1830 changed.
1831
Georg Brandlfee0f442010-05-22 21:26:21 +00001832- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001833 on 64-bit machines. The shift count for either left or right shift is
1834 permitted to be up to sys.maxsize.
1835
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001836- Ensure that tokenization of identifiers is not affected by locale.

1841
Georg Brandlfee0f442010-05-22 21:26:21 +00001842- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1843 with a non-empty format string. This is an effort to future-proof user
1844 code. If a derived class does not currently implement __format__ but later
1845 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001846 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001847 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001848
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001849- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001862- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001863 (SIGINT). If an error occurs while importing the site module, the error is

1879
Georg Brandlfee0f442010-05-22 21:26:21 +00001880- Issue #8257: The Decimal construct now accepts a float instance directly,
1881 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001882
1883 >>> Decimal(1.1)
1884 Decimal('1.100000000000000088817841970012523233890533447265625')
1885
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001886- collections.Counter() now supports a subtract() method.
1887
Georg Brandlfee0f442010-05-22 21:26:21 +00001888- The functools module now has a total_ordering() class decorator to simplify
1889 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001897- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1898 InvalidOperation instead of returning False. (Comparisons involving a quiet
1899 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1900 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001901
Georg Brandlfee0f442010-05-22 21:26:21 +00001902- Issue #2531: Comparison operations between floats and Decimal instances now
1903 return a result based on the numeric values of the operands; previously they
1904 returned an arbitrary result based on the relative ordering of id(float) and
1905 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001906
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001907- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001908 argument `-` which tells it to read files to compile from stdin. Each line is
1909 read on demand and the named file is compiled immediately. (Original patch by
1910 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001915- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1916 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001917 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001918
Georg Brandlfee0f442010-05-22 21:26:21 +00001919- Comparisons using one of <, <=, >, >= between a complex instance and a
1920 Fractions instance now raise TypeError instead of returning True/False. This
1921 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1922 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001923

R. David Murrayf28fd242010-02-23 00:24:49 +00002242 is run with the -OO flag. Tests requiring docstrings are skipped.
2243
Georg Brandlba83f822010-03-14 09:50:54 +00002244- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2245 now also used by regrtest to run all the tests in a temporary directory. The
2246 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent

Georg Brandlba83f822010-03-14 09:50:54 +00002284- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2285 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2286 returning NULL. The macro now returns a statically allocated empty string
2287 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002340 file position when calling `truncate()`. It would previously change the file
2341 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002342 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2345 class used to represent files stored inside an archive. The new
2346 implementation is significantly faster and can be wrapped in a
2347 ``io.BufferedReader`` object for more speedups. It also solves an issue
2348 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002359- Issue #7748: Since unicode values are supported for some metadata options in
2360 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2361 encoded string for them. This ensures that the upload and register commands
2362 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00002445- Issue #5080: A number of functions and methods previously produced a

2447 These functions and methods now raise TypeError instead. The majority of the
2448 effects of this change are in the extension modules, but some core functions
2449 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2450 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002633- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2634 decimal string that's guaranteed to round back to x under correct rounding
2635 (with round-half-to-even rounding mode). Previously it gave a string based on
2636 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2637 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2638 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002639
Georg Brandlba83f822010-03-14 09:50:54 +00002640- Issue #7117: On almost all platforms: float-to-string and string-to-float
2641 conversions within Python are now correctly rounded. Places these conversions
2642 occur include: str for floats and complex numbers; the float and complex
2643 constructors; old-style and new-style numeric formatting; serialization and
2644 deserialization of floats and complex numbers using marshal, pickle and json;
2645 parsing of float and imaginary literals in Python code; Decimal-to-float
2646 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002647
Georg Brandlba83f822010-03-14 09:50:54 +00002648 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2649 providing correctly-rounded strtod and dtoa C functions. This code is
2650 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2651 the C compiler. There may be a small number of platforms on which correct
2652 operation of this code cannot be guaranteed, so the code is not used: notably,
2653 this applies to platforms where the C double format is not IEEE 754 binary64,
2654 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2655 and Python's configure script is unable to determine how to change the FPU
2656 precision. On these platforms conversions use the platform strtod and dtoa,
2657 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002659- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2660 uses the correctly-rounded string <-> float conversions described above (when
2661 available), and so produces correctly rounded results that will display nicely
2662 under the float repr. There are two related small changes: (1) round now
2663 accepts any class with an ``__index__()`` method for its second argument (but
2664 no longer accepts floats for the second argument), and (2) an excessively
2665 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2666 raises an exception.

2816 of 12. Previously, the behavior the same but with a default precision of 6.

Georg Brandlba83f822010-03-14 09:50:54 +00003043- On windows, ``os.chdir()`` given unicode was not working if

3045 this code path is really executed because I cannot move to such directory on
3046 win2k)

3072 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4448
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004449- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4450 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4451 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4452 ``printf`` function, whereas PyString_FromFormat has an independent
4453 implementation and uses "%zd" on all platforms for size_t values.
4454 This makes a difference on win64, where ``printf`` needs "%Id" to display
4455 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004457- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4461 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00004474- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004475 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4476 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4477 when given a tuple of classes as second argument, were looking up
4478 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4479 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004550 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4551 for catch_warnings() also led to an improvement in the raising of a
4552 DeprecationWarning related to warnings.warn_explicit().
4553
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004554- The deprecation warnings for the old camelCase threading API were removed.

4576
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004577- Issue #2975: When compiling several extension modules with Visual Studio 2008
4578 from the same python interpreter, some environment variables would grow
4579 without limit.
4580
Benjamin Peterson37346b22008-08-23 20:27:43 +00004581- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4582 exploitation of poor argument checking.
4583
Gerhard Häringef2276b2008-09-12 13:54:06 +00004584- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4585
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004586- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4587 remaining ones have "pysqlite_" prefix.
4588
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004589- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4597 wrapper for warnings.catch_warnings() that makes it easier to check
4598 that expected warning messages are being reported.
4599

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004618What's New in Python 2.6 beta 3?
4619================================
4620
Barry Warsaw07a4a382008-08-21 01:15:08 +00004621*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004622
4623Core and Builtins
4624-----------------
4625
Guido van Rossumf8402962008-08-20 15:01:50 +00004626- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4627 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4628 extensions do not automatically benefit from the class attribute
4629 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4630 to their tp_flags field if they care. This is a backwards
4631 compatibility feature; in 3.0, all types will use the cache by
4632 default.
4633
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004634- Keyword arguments can now follow starred arguments. (``f(a, *args,
4635 keyword=23)`` is now valid syntax.)
4636
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004637- ctypes function pointers that are COM methods have a boolean True
4638 value again.
4639
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004640- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4641 by denying s# to parse objects that have a releasebuffer procedure,
4642 and introducing s*.
4643
Georg Brandl1e13ea92008-08-11 09:07:59 +00004644- Issue #3537: Fix an assertion failure when an empty but presized dict
4645 object was stored in the freelist.
4646
Mark Dickinsonb6467572008-08-04 21:30:09 +00004647- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4648 ValueError consistently across platforms.
4649
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004650- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4651 (64bit Unix, for example), unichr() would truncate its argument and return
4652 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4653
Neal Norwitze7d8be82008-07-31 17:17:14 +00004654- Apply security patches from Apple.
4655
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004656- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4657 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4658
Antoine Pitrou92f82162008-07-25 22:22:08 +00004659- Issue #1819: function calls with several named parameters are now on
4660 average 35% faster (as measured by pybench).
4661
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004662- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4663 the python debugger steps into a class statement: the free variables (local
4664 variables defined in an outer scope) would be deleted from the outer scope.
4665
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004666- Issue #2620: Overflow checking when allocating or reallocating memory
4667 was not always being done properly in some python types and extension
4668 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4669 all been updated to perform better checks and places in the code that
4670 would previously leak memory on the error path when such an allocation
4671 failed have been fixed.
4672
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004673Library
4674-------
4675
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004676- Issue #3612: Added some missing basic types in ctypes.wintypes.
4677
Benjamin Petersone977ad42008-08-20 01:42:01 +00004678- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4679 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4680
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004681- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4682 version reported by these tools does not necessarily follow the python
4683 version numbering scheme, so the module is less strict when parsing it.
4684
Nick Coghlanf70385a2008-08-18 12:42:46 +00004685- Issue #2235: Added Py3k warnings for types which will become unhashable
4686 under the stricter __hash__ inheritance rules in 3.0. Several types
4687 which did not meet the rules for hash invariants and were already
4688 unhashable in 3.0 have now been explicitly flagged as unhashable in
4689 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4690 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4691
Brett Cannon88f801d2008-08-18 00:46:22 +00004692- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4693 imported into the module but exposed as part of the module's API.
4694
Brett Cannon7b96f072008-08-18 00:41:11 +00004695- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4696
Brett Cannon46225e72008-08-18 00:36:52 +00004697- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004699- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4700
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004701- Issue #3575: Incremental decoder's decode function now takes bytearray
4702 by using 's*' instead of 't#'.
4703
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004704- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004705 fails unicode conversion on 2nd parameter. (windows only)
4706
Georg Brandl222e2082010-08-01 22:27:39 +00004707- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004708 in a redirect.
4709
Brett Cannonabe423e2008-08-16 21:47:07 +00004710- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004711 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004712
Facundo Batistaeb90b782008-08-16 14:44:07 +00004713- Issue #2776: fixed small issue when handling an URL with double slash
4714 after a 302 response in the case of not going through a proxy.
4715
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004716- Issue #2676: in the email package, content-type parsing was hanging on
4717 pathological input because of quadratic or exponential behaviour of a
4718 regular expression.
4719
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004720- Issue #3476: binary buffered reading through the new "io" library is now
4721 thread-safe.
4722
Brett Cannonbf3157b2008-08-14 05:00:03 +00004723- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4724 since mimetools itself is deprecated. Because modules are cached, all
4725 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4726
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004727- Issue #3134: shutil referenced undefined WindowsError symbol.
4728
Robert Schuppenies14646332008-08-10 11:01:53 +00004729- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4730 menu entries were not deleted.
4731
Brett Cannon83e81842008-08-09 23:30:55 +00004732- Copied the implementation of reduce() to _functools.reduce() to have a
4733 version that did not raise a DeprecationWarning under -3.
4734
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004735- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4736 a MemoryError rather than silently stop the iteration.
4737
Guido van Rossum59ce9012008-08-09 14:55:34 +00004738- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4739 to _sre.compile() will now be rejected. This should not affect anybody
4740 since the re.compile() function never generates invalid re-bytecode.
4741
Skip Montanaroa032bf42008-08-08 22:52:51 +00004742- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4743 upon first access it can be automatically initialized from the csv file if
4744 it wasn't initialized during instantiation.
4745
Brett Cannon3aa2a492008-08-06 22:28:09 +00004746- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4747 the reload() built-in has been removed.
4748
Brett Cannon7e30b672008-08-04 21:52:25 +00004749- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004750 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004761 asking for a specific length. This problem only affected files opened
4762 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004763

4788 file name rather than a ZipInfo instance, so files are extracted with
4789 mode 0600 rather than 000 under Unix.
4790
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004791- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4808 regarding lack of coverage of new-style classes have also been
4809 removed, since the coverage is now fairly reasonable.

4819
Georg Brandl3e483f62008-07-16 22:57:41 +00004820- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4821 its methods now allow for items objects that can be converted to
4822 an integer using operator.index().
4823
Mark Dickinson64b7e502008-07-16 09:40:03 +00004824- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4825 produced a ValueError instead of giving the correct float.
4826
Eric Smitha5fa5a22008-07-16 00:11:49 +00004827- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4828 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4829
Mark Dickinson7103aa42008-07-15 19:08:33 +00004830- Issue #3008: the float type has a new instance method 'float.hex'
4831 and a new class method 'float.fromhex' to convert floating-point
4832 numbers to and from hexadecimal strings, respectively.
4833
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004834- Issue #2235: __hash__ is once again inherited by default. To allow
4835 collections.Hashable to remain meaningful in the presence of the
4836 default hash implementation (object.__hash__), it is now possible
4837 to explicit block inheritance of hash by setting __hash__=None at
4838 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4839 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00004841- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4842 the parent module cannot be found while performing an absolute import.
4843 This means that an incorrectly defined __package__ attribute will
4844 now only prevent relative imports in that module rather than causing
4845 all imports from that module to fail.
4846
Nick Coghlan14ff9942008-07-08 14:21:42 +00004847- Issue #2517: Allow unicode messages in Exceptions again by correctly

4858
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004859- Issue #3004: Minor change to slice.indices(): the start and stop
4860 arguments are now treated identically, making the behaviour easier
4861 to describe and understand. For example, slice(None, -10,
4862 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4863 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4864 10, -1).

4907 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004908 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005380- Issue #1631171: Re-implement the 'warnings' module in C (the
5381 original Python code has been kept as backup). This will allow for
5382 using the 'warning's machinery in such places as the parser where
5383 use of pure Python code is not possible. Both the ``showarning()``
5384 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- Issue #2550: The approach used by client/server code for obtaining
5451 ports to listen on in network-oriented tests has been refined in an
5452 effort to facilitate running multiple instances of the entire
5453 regression test suite in parallel without issue.
5454 test_support.bind_port() has been fixed such that it will always
5455 return a unique port -- which wasn't always the case with the
5456 previous implementation, especially if socket options had been set
5457 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5458 new implementation of bind_port() will actually raise an exception
5459 if it is passed an AF_INET/SOCK_STREAM socket with either the
5460 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5461 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5462 the socket it's been passed. This currently only applies to
5463 Windows. This option prevents any other sockets from binding to the
5464 host/port we've bound to, thus removing the possibility of the
5465 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5466 when a second SOCK_STREAM socket binds and accepts to a host/port
5467 that's already been bound by another socket. The optional preferred
5468 port parameter to bind_port() has been removed. Under no
5469 circumstances should tests be hard coding ports!
5470
5471 test_support.find_unused_port() has also been introduced, which will
5472 pass a temporary socket object to bind_port() in order to obtain an
5473 unused port. The temporary socket object is then closed and
5474 deleted, and the port is returned. This method should only be used
5475 for obtaining an unused port in order to pass to an external program
5476 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5477 a parameter to a server-oriented class that doesn't give you direct
5478 access to the underlying socket used.
5479
5480 Finally, test_support.HOST has been introduced, which should be used
5481 for the host argument of any relevant socket calls (i.e. bind and
5482 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005483
5484 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005486 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5487 test_asynchat and test_socket_ssl.
5488
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 It is now possible for multiple instances of the regression test
5490 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005656- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
5657 values on 32-bit vs. 64-bit python interpreters. Both were correct,
5658 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00005769- Added the future_builtins module, which contains hex() and oct().
5770 These are the PEP 3127 version of these functions, designed to be
5771 compatible with the hex() and oct() builtins from Python 3.0. They
5772 differ slightly in their output formats from the existing, unchanged
5773 Python 2.6 builtins. The expected usage of the future_builtins
5774 module is:
5775 from future_builtins import hex, oct
5776
Eric Smith7ef40bf2008-02-20 23:34:22 +00005777- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5778 exponents for exponents with absolute value < 100. Follows C99
5779 standard. This is a change on Windows, which would use 3 digits.
5780 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5781 so that any alterations it does to the resulting string will be
5782 available in stringlib/formatter.h (for float.__format__).
5783
Eric Smith5a3c1352008-02-19 13:21:56 +00005784- Implemented PEP 3101, Advanced String Formatting. This adds a new
5785 builtin format(); a format() method for str and unicode; a
5786 __format__() method to object, str, unicode, int, long, float, and
5787 datetime; the class string.Formatter; and the C API
5788 PyObject_Format().
5789
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- Fixed several potential crashes, all caused by specially crafted
5791 __del__ methods exploiting objects in temporarily inconsistent
5792 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005793
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005794- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005795 prevent a possible crash: an Abstract Base Class would try to access
5796 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005797

Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Clear all free lists during a gc.collect() of the highest generation
5802 in order to allow pymalloc to free more arenas. Python may give back
5803 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005804
Georg Brandl3ee81df2008-05-17 18:14:43 +00005805- Issue #2045: Fix an infinite recursion triggered when printing a
5806 subclass of collections.defaultdict, if its default_factory is set
5807 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005808
Christian Heimesf75dbef2008-02-08 00:11:31 +00005809- Fixed a minor memory leak in dictobject.c. The content of the free
5810 list was not freed on interpreter shutdown.
5811
Georg Brandl21e99f42010-03-07 15:23:59 +00005812- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005814
Georg Brandl3ee81df2008-05-17 18:14:43 +00005815- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5816 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005817 to compact the internal free lists of pre-allocted ints and floats.
5818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5820 calls. Python expected the return type int but the fork familie
5821 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005822
Georg Brandl3ee81df2008-05-17 18:14:43 +00005823- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005835- Patch #1473257: generator objects gain a gi_code attribute. This is
5836 the same object as the func_code attribute of the function that
5837 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005838
Georg Brandl3ee81df2008-05-17 18:14:43 +00005839- Issue #1920: "while 0" statements were completely removed by the
5840 compiler, even in the presence of an "else" clause, which is
5841 supposed to be run when the condition is false. Now the compiler
5842 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005843
Guido van Rossumeead05f2008-01-24 18:21:02 +00005844- A few crashers fixed: weakref_in_del.py (issue #1377858);
5845 loosing_dict_ref.py (issue #1303614, test67.py);
5846 borrowed_ref_[34].py (not in tracker).
5847
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005848- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005849 suppressed while an extension is loaded by calling SetErrorMode in
5850 dynload_win.c. The error is still reported properly.
5851
Georg Brandl3ee81df2008-05-17 18:14:43 +00005852- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005853 several extension methods and modules do not work without unicode
5854 support.
5855
Georg Brandl26543b12008-01-21 18:36:51 +00005856- Issue #1882: when compiling code from a string, encoding cookies in the
5857 second line of code were not always recognized correctly.
5858
Georg Brandl14404b62008-01-19 19:27:05 +00005859- Issue #1679: "0x" was taken as a valid integer literal.
5860
Georg Brandl6caad7d2008-01-26 14:19:22 +00005861- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005862 added.
5863
Christian Heimesc94e2b52008-01-14 04:13:37 +00005864- sys.float_info / PyFloat_GetInfo: The floating point information
5865 object was converted from a dict to a specialized structseq object.
5866
Georg Brandl3ee81df2008-05-17 18:14:43 +00005867- Patch #1816: Added sys.flags structseq. It exposes the status of
5868 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005869
Georg Brandl3ee81df2008-05-17 18:14:43 +00005870- Objects/structseq.c: Implemented new structseq representation. The
5871 patch makes structseqs (e.g. the return value of os.stat) more
5872 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005873
Georg Brandl3ee81df2008-05-17 18:14:43 +00005874- Patch #1700288: added a type attribute cache that caches method

5883 envvar and sys.dont_write_bytecode attribute. All these can be set
5884 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005885
Georg Brandl3ee81df2008-05-17 18:14:43 +00005886- Improve some exception messages when Windows fails to load an
5887 extension module. Now we get for example '%1 is not a valid Win32
5888 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005896 and INF. float("nan"), float("inf") and float("-inf") now work on
5897 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005899- Compiler now generates simpler and faster code for dictionary
5900 literals. The oparg for BUILD_MAP now indicates an estimated
5901 dictionary size. There is a new opcode, STORE_MAP, for adding
5902 entries to the dictionary.

5914
Nick Coghlanef01d822007-12-03 12:55:17 +00005915- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005931- Patch #1739468: Directories and zipfiles containing a __main__.py
5932 file can now be directly executed by passing their name to the
5933 interpreter. The directory/zipfile is automatically inserted as the
5934 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005936- Issue #1265: Fix a problem with sys.settrace, if the tracing
5937 function uses a generator expression when at the same time the
5938 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005939
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005940- sets and frozensets now have an isdisjoint() method.

5945
Georg Brandl21e99f42010-03-07 15:23:59 +00005946- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5948 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Issue #1686386: Tuple's tp_repr did not take into account the
5951 possibility of having a self-referential tuple, which is possible
5952 from C code. Nor did object's tp_str consider that a type's tp_str
5953 could do something that could lead to an inifinite recursion.
5954 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5955 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005956
Georg Brandl3ee81df2008-05-17 18:14:43 +00005957- Issue #1164: It was possible to trigger deadlock when using the
5958 'print' statement to write to a file since the GIL was not released
5959 as needed. Now PyObject_Print() does the right thing along with
5960 various tp_print implementations of the built-in types and those in
5961 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005962
Georg Brandl3ee81df2008-05-17 18:14:43 +00005963- Issue #1147: Exceptions were directly allowing string exceptions in
5964 their throw() method even though string exceptions no longer
5965 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005966
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967- Issue #1096: Prevent a segfault from getting the repr of a very
5968 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005969
Brett Cannon1e534b52007-09-07 04:18:30 +00005970- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005971 PyObject_Call() never calling back out to Python code to trigger
5972 recursion depth updates/checks. Required the creation of a static
5973 RuntimeError instance in case normalizing an exception put the
5974 recursion check value past its limit. Fixes crashers
5975 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005976
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005990- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991 __*__ attributes. (Some already existed, e.g., __doc__ and
5992 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005993
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005994- Add -3 option to the interpreter to warn about features that are
5995 deprecated and will be changed/removed in Python 3.0.
5996
Georg Brandl2134e752007-05-21 20:34:16 +00005997- Patch #1686487: you can now pass any mapping after '**' in function
5998 calls.
5999
Collin Winter62903052007-05-18 23:11:24 +00006000- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001 "except E as target:". This is to provide forwards compatibility
6002 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006003
Brett Cannon229cee22007-05-05 01:34:02 +00006004- Deprecate BaseException.message as per PEP 352.
6005
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006007 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006008
Vinay Sajip8549ce32007-05-06 17:53:37 +00006009- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006010 setting a plain string, ie don't expand to single letter identifiers.
6011
Raymond Hettinger13936692007-04-11 18:40:58 +00006012- Request #1191699: Slices can now be pickled.
6013
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006014- Request #1193128: str.translate() now allows a None argument for
6015 translations that only remove characters without re-mapping the
6016 remaining characters.
6017
Georg Brandl5cb76c12007-03-21 09:00:39 +00006018- Patch #1682205: a TypeError while unpacking an iterable is no longer
6019 masked by a generic one with the message "unpack non-sequence".
6020
Neal Norwitzaa754b72007-03-21 06:39:48 +00006021- Remove unused file Python/fmod.c.
6022
Guido van Rossum143b5642007-03-23 04:58:42 +00006023- Bug #1683368: The object.__init__() and object.__new__() methods are
6024 now stricter in rejecting excess arguments. The only time when
6025 either allows excess arguments is when it is not overridden and the
6026 other one is. For backwards compatibility, when both are
6027 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006028 warning later). Also, type.__init__() insists on the same signature
6029 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006030
Georg Brandl3ee81df2008-05-17 18:14:43 +00006031- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6032 object to complex using its __complex__() method before falling back
6033 to the __float__() method. Therefore, the functions in the cmath
6034 module now can operate on objects that define a __complex__()
6035 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006036
Georg Brandl3ee81df2008-05-17 18:14:43 +00006037- Patch #1623563: allow __class__ assignment for classes with
6038 __slots__. The old and the new class are still required to have the
6039 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006040
Georg Brandl3ee81df2008-05-17 18:14:43 +00006041- Patch #1642547: Fix an error/crash when encountering syntax errors

6045 ``object.__reduce_ex__()`` is called with an object that is faking
6046 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006047
Georg Brandl3ee81df2008-05-17 18:14:43 +00006048- Patch #1680015: Don't modify __slots__ tuple if it contains an

6052
Georg Brandl7b9c5552007-03-12 14:30:05 +00006053- Bug #1678647: write a newline after printing an exception in any
6054 case, even when converting the value to a string failed.
6055
Georg Brandl871f1bc2007-03-12 13:17:36 +00006056- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006057 its argument, if it exists. If not, it will work like before. This
6058 allows customizing the output of dir() in the presence of a
6059 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006060
Collin Winter276887b2007-03-12 16:11:39 +00006061- Patch #922167: Python no longer segfaults when faced with infinitely
6062 self-recursive reload() calls (as reported by bug #742342).
6063
Georg Brandl3ee81df2008-05-17 18:14:43 +00006064- Patch #1675981: remove unreachable code from ``type.__new__()``
6065 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006067- Patch #1491866: change the complex() constructor to allow
6068 parthensized forms. This means complex(repr(x)) now works instead of
6069 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006070
Georg Brandlaa2321b2007-03-07 00:40:28 +00006071- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006072 makes the filenames the warning module prints much more sensible
6073 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006074

Georg Brandl098cd692007-03-06 12:17:50 +00006085
Georg Brandl0fca97a2007-03-05 22:28:08 +00006086- Patch #1674228: when assigning a slice (old-style), check for the
6087 sq_ass_slice instead of the sq_slice slot.
6088
Georg Brandl3ee81df2008-05-17 18:14:43 +00006089- When printing an unraisable error, don't print exceptions. before
6090 the name. This duplicates the behavior whening normally printing
6091 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- Patch #1530482: add pydoc.render_doc() which returns the

6657
Georg Brandl92a6bae2007-03-13 17:43:32 +00006658- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006659 are set for invalid interpolation sequences that would lead to
6660 errors on reading back those values.

6714
Georg Brandl3ee81df2008-05-17 18:14:43 +00006715- unittest now verifies more of its assumptions. In particular,
6716 TestCase and TestSuite subclasses (not instances) are no longer
6717 accepted in TestSuite.addTest(). This should cause no
6718 incompatibility since it never made sense with ordinary subclasses
6719 -- the failure just occurred later, with a more cumbersome
6720 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007007 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007009 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007108- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109 time so that opening a database previously created with the DB_DUP
7110 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7111 opens. Specifically: dictionary assignment to a DB object will
7112 replace all values for a given key when the database allows
7113 duplicate values. DB users should use DB.put(k, v) when they want
7114 to store duplicates; not DB[k] = v.

7123 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007393- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007394 periodic threadstate and signal checking in tight loops. By
7395 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00007453
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7455 to ``PyTuple_SetItem``, it can be used to populate a brand new

7468
Georg Brandl3ee81df2008-05-17 18:14:43 +00007469- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7470 of w# format code incorrectly truncated the length to an int, even
7471 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7472 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007473

7500 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007501
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7503 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007504
Georg Brandl3ee81df2008-05-17 18:14:43 +00007505- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
