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

Mark Dickinsondbbed042011-09-19 16:38:08 +010051- Issue #12973: Fix overflow checks that invoked undefined behaviour in
52 int.__pow__. These overflow checks were causing int.__pow__ to produce
53 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010054 compiler optimizing the check away. Also fix similar overflow checks
55 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
56 bugs caused test failures with recent versions of Clang.

68 cleared by the garbage collector. This fixes a segfault when an instance
69 and its type get caught in a reference cycle, and the instance's
70 deallocator calls one of the methods on the type (e.g. when subclassing
71 IOBase). Diagnosis and patch by Davide Rizzo.
72
Victor Stinnerba8b3a22011-07-08 02:07:45 +020073- Issue #12501: Adjust callable() warning: callable() is only not supported in

75

81 raw_input() interrupted by CTRL+c.
82
Łukasz Langa7a153902011-10-18 17:16:00 +020083- Issue #10860: httplib now correctly handles an empty port after port
84 delimiter in URLs.
85
Barry Warsawc5643282011-07-19 17:06:30 -040086- dict_proxy objects now display their contents rather than just the class

Ned Deily87e82bb2011-06-28 19:52:59 -0700320- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
321 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
322 interpreter process. This could cause failures in non-Distutils subprocesses
323 and was unreliable since tests or user programs could modify the interpreter
324 environment after Distutils set it. Instead, have Distutils set the the
325 deployment target only in the environment of each build subprocess. It is
326 still possible to globally override the default by setting
327 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
328 greater or equal to the default value, the value with which the interpreter
329 was built.

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

1257 handles non-blocking readinto() returning None correctly.

1260 SSLSocket.sendto() to match the corresponding socket methods. Also,
1261 fix various SSLSocket methods to raise socket.error rather than an

1263 by Andrew Bennetts.

1272
Raymond Hettinger20397532010-09-12 02:11:45 +00001273- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1274 This prevents user-created self-referencing ordered dictionaries from
1275 becoming permanently uncollectable GC garbage. The downside is that
1276 removing __del__ means that the internal doubly-linked list has to wait for
1277 GC collection rather than freeing memory immediately when the refcnt drops
1278 to zero.
1279
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001280- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1283
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001284- Issue #9792: In case of connection failure, socket.create_connection()
1285 would swallow the exception and raise a new one, making it impossible
1286 to fetch the original errno, or to filter timeout errors. Now the
1287 original error is re-raised.
1288
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001289- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1290 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1291 be updated back after the system call. Original patch by Brian Brazil.

1307 falling into recursion.
1308
R. David Murray7c4bf552010-08-25 01:45:57 +00001309- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1310 character years even if the message contains RFC822 two character years.
1311
Daniel Stutzbach91287322010-08-24 21:09:30 +00001312- Issue #8750: Fixed MutableSet's methods to correctly handle

1325
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001326- Issue #9617: Signals received during a low-level write operation aren't
1327 ignored by the buffered IO layer anymore.
1328
Benjamin Peterson52c36052010-08-21 03:03:22 +00001329- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1331
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001332- Issue #9626: the view methods for collections.OrderedDict() were returning

1341 and a BadZipfile error is raised if it doesn't match (as used to be the
1342 case in Python 2.5 and earlier).
1343
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001344- Issue #9550: a BufferedReader could issue an additional read when the
1345 original read request had been satisfied, which could block indefinitely
1346 when the underlying raw IO channel was e.g. a socket. Report and original
1347 patch by Jason V. Miller.
1348
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001349- Issue #9551: Don't raise TypeError when setting the value to None for

1368 This is how it is supposed to work, wget and curl do the same. Previous

1377 the option character for the added 'h/help' option if prefix_chars
1378 does not contain a '-', instead of raising an error.
1379

1740 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002098 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2099 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2100 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2121-----------------
2122
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002123- Issue #7301: Add environment variable $PYTHONWARNINGS.
2124
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002125- Issue #8329: Don't return the same lists from select.select when no fds are
2126 changed.
2127
Georg Brandlfee0f442010-05-22 21:26:21 +00002128- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002129 on 64-bit machines. The shift count for either left or right shift is
2130 permitted to be up to sys.maxsize.
2131
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002132- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00002134- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002135
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002136- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2137
Georg Brandlfee0f442010-05-22 21:26:21 +00002138- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2139 with a non-empty format string. This is an effort to future-proof user
2140 code. If a derived class does not currently implement __format__ but later
2141 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002142 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002143 Python 3.3 and it will be an error in Python 3.4.

Victor Stinner66644262010-03-10 22:30:19 +00002158- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002159 (SIGINT). If an error occurs while importing the site module, the error is
2160 printed and Python exits. Initialize the GIL before importing the site

2175
Georg Brandlfee0f442010-05-22 21:26:21 +00002176- Issue #8257: The Decimal construct now accepts a float instance directly,
2177 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002178
2179 >>> Decimal(1.1)
2180 Decimal('1.100000000000000088817841970012523233890533447265625')
2181
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002182- collections.Counter() now supports a subtract() method.
2183
Georg Brandlfee0f442010-05-22 21:26:21 +00002184- The functools module now has a total_ordering() class decorator to simplify
2185 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002186
Georg Brandlfee0f442010-05-22 21:26:21 +00002187- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +00002193- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2194 InvalidOperation instead of returning False. (Comparisons involving a quiet
2195 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2196 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002197
Georg Brandlfee0f442010-05-22 21:26:21 +00002198- Issue #2531: Comparison operations between floats and Decimal instances now
2199 return a result based on the numeric values of the operands; previously they
2200 returned an arbitrary result based on the relative ordering of id(float) and
2201 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002202
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002203- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002204 argument `-` which tells it to read files to compile from stdin. Each line is
2205 read on demand and the named file is compiled immediately. (Original patch by
2206 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002211- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2212 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002213 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002214
Georg Brandlfee0f442010-05-22 21:26:21 +00002215- Comparisons using one of <, <=, >, >= between a complex instance and a
2216 Fractions instance now raise TypeError instead of returning True/False. This
2217 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2218 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002229- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002230 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2231 silenced.

Georg Brandlba83f822010-03-14 09:50:54 +00002575- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2576 and add the additional members returned in an OSVERSIONINFOEX structure. The
2577 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002580- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2581 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2582 returning NULL. The macro now returns a statically allocated empty string
2583 instead.

2593 strings,
2594 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2595 numeric strings corresponding to subnormal values,
2596 (3) a memory leak for some values large enough to cause overflow, and
2597 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002628- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002629 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002635- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002636 file position when calling `truncate()`. It would previously change the file
2637 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002638 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2639
Georg Brandlba83f822010-03-14 09:50:54 +00002640- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2641 class used to represent files stored inside an archive. The new
2642 implementation is significantly faster and can be wrapped in a
2643 ``io.BufferedReader`` object for more speedups. It also solves an issue
2644 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002655- Issue #7748: Since unicode values are supported for some metadata options in
2656 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2657 encoded string for them. This ensures that the upload and register commands
2658 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002727What's New in Python 2.7 alpha 2?
2728=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00002730*Release date: 2010-01-09*

2733-----------------
2734
Georg Brandlba83f822010-03-14 09:50:54 +00002735- The ``__complex__()`` method is now looked up on the class of instances to
2736 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002737
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002738- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2739 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2740
Mark Dickinson1b34d252010-01-01 17:27:30 +00002741- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002742 DeprecationWarning when passed a float argument where an integer was expected.
2743 These functions and methods now raise TypeError instead. The majority of the
2744 effects of this change are in the extension modules, but some core functions
2745 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2746 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002747
Benjamin Peterson0f02d392009-12-30 19:34:10 +00002748- Issue #7604: Deleting an unset slotted attribute did not raise an
2749 AttributeError.
2750

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00002755
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002756- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2757 used to drop the time part of the result.
2758
Georg Brandlba83f822010-03-14 09:50:54 +00002759- Issue #1811: Improve accuracy and cross-platform consistency for true division
2760 of integers: the result of a/b is now correctly rounded for ints a and b (at
2761 least on IEEE 754 platforms), and in particular does not depend on the
2762 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002763
Georg Brandlba83f822010-03-14 09:50:54 +00002764- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2765 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2766 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002767

Ronald Oussoren92919a62009-12-24 13:30:58 +00002769 executables on OSX.
2770
Georg Brandlba83f822010-03-14 09:50:54 +00002771 These executables now work properly with the arch(1) command: ``arch -ppc
2772 python`` will start a universal binary version of python in PPC mode (unlike
2773 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002774
Georg Brandlba83f822010-03-14 09:50:54 +00002775- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2776 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00002777
Benjamin Peterson4895af42009-12-13 16:36:53 +00002778- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +00002787- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
2788 allowing for a maximum number of tasks within the pool to be completed by the
2789 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +00002790
Georg Brandlba83f822010-03-14 09:50:54 +00002791- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

Antoine Pitrou80157252010-01-08 19:20:17 +00002795- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002796 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2797 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +00002798 Xicluna.

Georg Brandlba83f822010-03-14 09:50:54 +00002816- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00002817 Initial patch by Brian Curtin.
2818
Georg Brandlba83f822010-03-14 09:50:54 +00002819- Distutils now correctly identifies the build architecture as "x86_64" when
2820 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00002821

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002832- Issue #7349: Make methods of file objects in the io module accept None as an
2833 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2834 the same as passing no argument.
2835
Georg Brandlba83f822010-03-14 09:50:54 +00002836- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
2837 argument like other file objects.
Benjamin Petersonc4771d22009-12-13 17:31:31 +00002838

Mark Dickinsona36507c2010-01-30 10:08:33 +00002857
Georg Brandlba83f822010-03-14 09:50:54 +00002858- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2859 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2860 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2861 float arguments for integer format codes (other than 'L'): previously an
2862 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2863 TypeError. For the 'L' format code (which previously had no warning) there is
2864 now a DeprecationWarning.

2913 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002914

Georg Brandlba83f822010-03-14 09:50:54 +00002929- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2930 decimal string that's guaranteed to round back to x under correct rounding
2931 (with round-half-to-even rounding mode). Previously it gave a string based on
2932 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2933 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2934 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002935
Georg Brandlba83f822010-03-14 09:50:54 +00002936- Issue #7117: On almost all platforms: float-to-string and string-to-float
2937 conversions within Python are now correctly rounded. Places these conversions
2938 occur include: str for floats and complex numbers; the float and complex
2939 constructors; old-style and new-style numeric formatting; serialization and
2940 deserialization of floats and complex numbers using marshal, pickle and json;
2941 parsing of float and imaginary literals in Python code; Decimal-to-float
2942 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002943
Georg Brandlba83f822010-03-14 09:50:54 +00002944 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2945 providing correctly-rounded strtod and dtoa C functions. This code is
2946 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2947 the C compiler. There may be a small number of platforms on which correct
2948 operation of this code cannot be guaranteed, so the code is not used: notably,
2949 this applies to platforms where the C double format is not IEEE 754 binary64,
2950 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2951 and Python's configure script is unable to determine how to change the FPU
2952 precision. On these platforms conversions use the platform strtod and dtoa,
2953 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002954
Georg Brandlba83f822010-03-14 09:50:54 +00002955- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2956 uses the correctly-rounded string <-> float conversions described above (when
2957 available), and so produces correctly rounded results that will display nicely
2958 under the float repr. There are two related small changes: (1) round now
2959 accepts any class with an ``__index__()`` method for its second argument (but
2960 no longer accepts floats for the second argument), and (2) an excessively
2961 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

3189 internal representation of integers, for performance reasons. Base 2**30 is
3190 enabled by default on 64-bit machines. Add --enable-big-digits option to
3191 configure, which overrides the default. Add sys.long_info structseq to
3192 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003255- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3256 existing .py counterpart, override the co_filename attributes of all code
3257 objects if the original filename is obsolete (which can happen if the file has

3312
Georg Brandlba83f822010-03-14 09:50:54 +00003313- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3314 file objects with closefd=False. The file descriptor is still kept open but
3315 the file object behaves like a closed file. The ``FileIO`` object also got a
3316 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003339- On windows, ``os.chdir()`` given unicode was not working if
3340 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3341 this code path is really executed because I cannot move to such directory on
3342 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003344- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3345 element is temporarily replaced with an equivalent frozenset. But the
3346 eventual KeyError would always report the empty ``frozenset()`` as the missing

3368 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3369 step. This avoids problems with counting UTF-8 bytes that ignores the effect

3371
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003372- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003375- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004745- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4746 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4747 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4748 ``printf`` function, whereas PyString_FromFormat has an independent
4749 implementation and uses "%zd" on all platforms for size_t values.

4751 64bit values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004846 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4847 for catch_warnings() also led to an improvement in the raising of a
4848 DeprecationWarning related to warnings.warn_explicit().
4849
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004850- The deprecation warnings for the old camelCase threading API were removed.

4872
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004873- Issue #2975: When compiling several extension modules with Visual Studio 2008
4874 from the same python interpreter, some environment variables would grow
4875 without limit.
4876
Benjamin Peterson37346b22008-08-23 20:27:43 +00004877- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4878 exploitation of poor argument checking.
4879
Gerhard Häringef2276b2008-09-12 13:54:06 +00004880- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4881
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004882- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4883 remaining ones have "pysqlite_" prefix.
4884
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004885- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004914What's New in Python 2.6 beta 3?
4915================================
4916
Barry Warsaw07a4a382008-08-21 01:15:08 +00004917*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004918
4919Core and Builtins
4920-----------------
4921
Guido van Rossumf8402962008-08-20 15:01:50 +00004922- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4923 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4924 extensions do not automatically benefit from the class attribute
4925 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4926 to their tp_flags field if they care. This is a backwards
4927 compatibility feature; in 3.0, all types will use the cache by
4928 default.
4929
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004930- Keyword arguments can now follow starred arguments. (``f(a, *args,
4931 keyword=23)`` is now valid syntax.)
4932
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004933- ctypes function pointers that are COM methods have a boolean True
4934 value again.
4935
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004936- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4937 by denying s# to parse objects that have a releasebuffer procedure,
4938 and introducing s*.
4939
Georg Brandl1e13ea92008-08-11 09:07:59 +00004940- Issue #3537: Fix an assertion failure when an empty but presized dict
4941 object was stored in the freelist.
4942
Mark Dickinsonb6467572008-08-04 21:30:09 +00004943- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4944 ValueError consistently across platforms.
4945
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004946- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4947 (64bit Unix, for example), unichr() would truncate its argument and return
4948 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4949
Neal Norwitze7d8be82008-07-31 17:17:14 +00004950- Apply security patches from Apple.
4951
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004952- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4953 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4954
Antoine Pitrou92f82162008-07-25 22:22:08 +00004955- Issue #1819: function calls with several named parameters are now on
4956 average 35% faster (as measured by pybench).
4957
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004958- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4959 the python debugger steps into a class statement: the free variables (local
4960 variables defined in an outer scope) would be deleted from the outer scope.
4961
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004962- Issue #2620: Overflow checking when allocating or reallocating memory
4963 was not always being done properly in some python types and extension
4964 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4965 all been updated to perform better checks and places in the code that
4966 would previously leak memory on the error path when such an allocation
4967 failed have been fixed.
4968
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004969Library
4970-------
4971
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004972- Issue #3612: Added some missing basic types in ctypes.wintypes.
4973
Benjamin Petersone977ad42008-08-20 01:42:01 +00004974- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4975 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4976
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004977- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4978 version reported by these tools does not necessarily follow the python
4979 version numbering scheme, so the module is less strict when parsing it.
4980
Nick Coghlanf70385a2008-08-18 12:42:46 +00004981- Issue #2235: Added Py3k warnings for types which will become unhashable
4982 under the stricter __hash__ inheritance rules in 3.0. Several types
4983 which did not meet the rules for hash invariants and were already
4984 unhashable in 3.0 have now been explicitly flagged as unhashable in
4985 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4986 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4987
Brett Cannon88f801d2008-08-18 00:46:22 +00004988- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4989 imported into the module but exposed as part of the module's API.
4990
Brett Cannon7b96f072008-08-18 00:41:11 +00004991- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4992
Brett Cannon46225e72008-08-18 00:36:52 +00004993- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004995- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4996
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004997- Issue #3575: Incremental decoder's decode function now takes bytearray
4998 by using 's*' instead of 't#'.
4999
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005000- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005001 fails unicode conversion on 2nd parameter. (windows only)
5002
Georg Brandl222e2082010-08-01 22:27:39 +00005003- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005004 in a redirect.
5005
Brett Cannonabe423e2008-08-16 21:47:07 +00005006- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005007 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005008
Facundo Batistaeb90b782008-08-16 14:44:07 +00005009- Issue #2776: fixed small issue when handling an URL with double slash
5010 after a 302 response in the case of not going through a proxy.
5011
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005012- Issue #2676: in the email package, content-type parsing was hanging on
5013 pathological input because of quadratic or exponential behaviour of a
5014 regular expression.
5015
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005016- Issue #3476: binary buffered reading through the new "io" library is now
5017 thread-safe.
5018
Brett Cannonbf3157b2008-08-14 05:00:03 +00005019- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5020 since mimetools itself is deprecated. Because modules are cached, all
5021 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5022
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005023- Issue #3134: shutil referenced undefined WindowsError symbol.
5024
Robert Schuppenies14646332008-08-10 11:01:53 +00005025- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5026 menu entries were not deleted.
5027
Brett Cannon83e81842008-08-09 23:30:55 +00005028- Copied the implementation of reduce() to _functools.reduce() to have a
5029 version that did not raise a DeprecationWarning under -3.
5030
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005031- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5032 a MemoryError rather than silently stop the iteration.
5033
Guido van Rossum59ce9012008-08-09 14:55:34 +00005034- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5035 to _sre.compile() will now be rejected. This should not affect anybody
5036 since the re.compile() function never generates invalid re-bytecode.
5037
Skip Montanaroa032bf42008-08-08 22:52:51 +00005038- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5039 upon first access it can be automatically initialized from the csv file if
5040 it wasn't initialized during instantiation.
5041
Brett Cannon3aa2a492008-08-06 22:28:09 +00005042- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5043 the reload() built-in has been removed.
5044
Brett Cannon7e30b672008-08-04 21:52:25 +00005045- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005046 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005057 asking for a specific length. This problem only affected files opened
5058 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005059

5085 mode 0600 rather than 000 under Unix.
5086

5104 regarding lack of coverage of new-style classes have also been
5105 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005113Core and Builtins
5114-----------------
5115
Georg Brandl3e483f62008-07-16 22:57:41 +00005116- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5117 its methods now allow for items objects that can be converted to
5118 an integer using operator.index().
5119
Mark Dickinson64b7e502008-07-16 09:40:03 +00005120- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5121 produced a ValueError instead of giving the correct float.
5122
Eric Smitha5fa5a22008-07-16 00:11:49 +00005123- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5124 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5125
Mark Dickinson7103aa42008-07-15 19:08:33 +00005126- Issue #3008: the float type has a new instance method 'float.hex'
5127 and a new class method 'float.fromhex' to convert floating-point
5128 numbers to and from hexadecimal strings, respectively.
5129
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005130- Issue #2235: __hash__ is once again inherited by default. To allow
5131 collections.Hashable to remain meaningful in the presence of the
5132 default hash implementation (object.__hash__), it is now possible
5133 to explicit block inheritance of hash by setting __hash__=None at
5134 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5135 level.
5136
Nick Coghlanb028f502008-07-13 14:52:36 +00005137- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5138 the parent module cannot be found while performing an absolute import.
5139 This means that an incorrectly defined __package__ attribute will
5140 now only prevent relative imports in that module rather than causing
5141 all imports from that module to fail.
5142
Nick Coghlan14ff9942008-07-08 14:21:42 +00005143- Issue #2517: Allow unicode messages in Exceptions again by correctly
5144 bypassing the instance dictionary when looking up __unicode__ on
5145 new-style classes.
5146
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005147- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5148 set to a custom object whose write() method happens to install
5149 another file in sys.stdout.
5150
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005151- Issue #3088: Corrected a race condition in classes derived from
5152 threading.local: the first member set by a thread could be saved in
5153 another thread's dictionary.
5154
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005155- Issue #3004: Minor change to slice.indices(): the start and stop
5156 arguments are now treated identically, making the behaviour easier
5157 to describe and understand. For example, slice(None, -10,
5158 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5159 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5160 10, -1).
5161
Georg Brandl278fc502008-07-19 12:46:12 +00005162- Issue #3219: Calling a function with repeated keyword arguments,
5163 f(a=2, a=23), would not cause a syntax error. This was a regression
5164 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005165
Georg Brandl278fc502008-07-19 12:46:12 +00005166- Issue #2862: Make int and float freelist management consistent with
5167 other freelists. Changes their CompactFreeList apis into
5168 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005169

5171-------
5172
Thomas Heller57adf222008-08-14 19:10:48 +00005173- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5174 api functions without holding the GIL, which could lead to a fatal
5175 error when they failed.
5176
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005177- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5178
Jesse Noller7fb96402008-07-17 21:01:05 +00005179- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

5184
Jesse Noller13e9d582008-07-16 14:32:36 +00005185- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5186 ForkingPickler.register() to resolve conflict with ctypes.
5187
Vinay Sajip51e65192008-07-18 09:01:10 +00005188- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005189
Thomas Heller880f5292008-07-15 19:39:38 +00005190- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5191 a valid dlerror() message.
5192
Thomas Heller2bad6572008-07-15 17:19:50 +00005193- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5194 incomplete structure was created.
5195
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005196- Issue #3339: dummy_thread.acquire() should not return None.
5197
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005198- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5199
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005200- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005201
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005202- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5203 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005204 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005205 content-length. The problem had been corrected in the 2.4 branch, but never
5206 merged into trunk.
5207
Georg Brandle78fbcc2008-07-05 10:13:36 +00005208- Issue #2663: add filtering capability to shutil.copytree().

5211
5212- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5213
5214- Issue #1746: Correct handling of zipfile archive comments (previously
5215 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005216 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005217
Vinay Sajip51e65192008-07-18 09:01:10 +00005218- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005219 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005220
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005221- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5222 handling is now the same as that of other special attributes like __name__).
5223
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005224- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5225 removal in Python 3.0 in favor of urllib2.urlopen().

5237
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00005238- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00005676- Issue #1631171: Re-implement the 'warnings' module in C (the
5677 original Python code has been kept as backup). This will allow for
5678 using the 'warning's machinery in such places as the parser where
5679 use of pure Python code is not possible. Both the ``showarning()``
5680 and ``formatwarning()`` gain an optional 'line' argument which is
5681 not called by default for backwards-compatibility reasons. Setting
5682 ``warnings.showwarning()`` to an implementation that lacks support
5683 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- Issue #2550: The approach used by client/server code for obtaining
5747 ports to listen on in network-oriented tests has been refined in an
5748 effort to facilitate running multiple instances of the entire
5749 regression test suite in parallel without issue.
5750 test_support.bind_port() has been fixed such that it will always
5751 return a unique port -- which wasn't always the case with the
5752 previous implementation, especially if socket options had been set
5753 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5754 new implementation of bind_port() will actually raise an exception
5755 if it is passed an AF_INET/SOCK_STREAM socket with either the
5756 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5757 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5758 the socket it's been passed. This currently only applies to
5759 Windows. This option prevents any other sockets from binding to the
5760 host/port we've bound to, thus removing the possibility of the
5761 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5762 when a second SOCK_STREAM socket binds and accepts to a host/port
5763 that's already been bound by another socket. The optional preferred
5764 port parameter to bind_port() has been removed. Under no
5765 circumstances should tests be hard coding ports!
5766
5767 test_support.find_unused_port() has also been introduced, which will
5768 pass a temporary socket object to bind_port() in order to obtain an
5769 unused port. The temporary socket object is then closed and
5770 deleted, and the port is returned. This method should only be used
5771 for obtaining an unused port in order to pass to an external program
5772 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5773 a parameter to a server-oriented class that doesn't give you direct
5774 access to the underlying socket used.
5775
5776 Finally, test_support.HOST has been introduced, which should be used
5777 for the host argument of any relevant socket calls (i.e. bind and
5778 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005779
5780 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005782 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5783 test_asynchat and test_socket_ssl.
5784
Georg Brandl3ee81df2008-05-17 18:14:43 +00005785 It is now possible for multiple instances of the regression test
5786 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006065- Added the future_builtins module, which contains hex() and oct().
6066 These are the PEP 3127 version of these functions, designed to be
6067 compatible with the hex() and oct() builtins from Python 3.0. They
6068 differ slightly in their output formats from the existing, unchanged
6069 Python 2.6 builtins. The expected usage of the future_builtins
6070 module is:
6071 from future_builtins import hex, oct
6072
Eric Smith7ef40bf2008-02-20 23:34:22 +00006073- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6074 exponents for exponents with absolute value < 100. Follows C99
6075 standard. This is a change on Windows, which would use 3 digits.
6076 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6077 so that any alterations it does to the resulting string will be
6078 available in stringlib/formatter.h (for float.__format__).
6079
Eric Smith5a3c1352008-02-19 13:21:56 +00006080- Implemented PEP 3101, Advanced String Formatting. This adds a new
6081 builtin format(); a format() method for str and unicode; a
6082 __format__() method to object, str, unicode, int, long, float, and
6083 datetime; the class string.Formatter; and the C API
6084 PyObject_Format().
6085
Georg Brandl3ee81df2008-05-17 18:14:43 +00006086- Fixed several potential crashes, all caused by specially crafted
6087 __del__ methods exploiting objects in temporarily inconsistent
6088 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006089
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006090- Issue #2115: Important speedup in setting __slot__ attributes. Also

6098 in order to allow pymalloc to free more arenas. Python may give back
6099 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006100
Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Issue #2045: Fix an infinite recursion triggered when printing a
6102 subclass of collections.defaultdict, if its default_factory is set
6103 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006104
Christian Heimesf75dbef2008-02-08 00:11:31 +00006105- Fixed a minor memory leak in dictobject.c. The content of the free
6106 list was not freed on interpreter shutdown.
6107
Georg Brandl21e99f42010-03-07 15:23:59 +00006108- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006110
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6112 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006113 to compact the internal free lists of pre-allocted ints and floats.
6114
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6116 calls. Python expected the return type int but the fork familie
6117 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006118

Georg Brandl3ee81df2008-05-17 18:14:43 +00006131- Patch #1473257: generator objects gain a gi_code attribute. This is
6132 the same object as the func_code attribute of the function that
6133 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006134
Georg Brandl3ee81df2008-05-17 18:14:43 +00006135- Issue #1920: "while 0" statements were completely removed by the
6136 compiler, even in the presence of an "else" clause, which is
6137 supposed to be run when the condition is false. Now the compiler
6138 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006139
Guido van Rossumeead05f2008-01-24 18:21:02 +00006140- A few crashers fixed: weakref_in_del.py (issue #1377858);

6147
Georg Brandl3ee81df2008-05-17 18:14:43 +00006148- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006149 several extension methods and modules do not work without unicode
6150 support.
6151

6154
Georg Brandl14404b62008-01-19 19:27:05 +00006155- Issue #1679: "0x" was taken as a valid integer literal.
6156
Georg Brandl6caad7d2008-01-26 14:19:22 +00006157- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006158 added.
6159
Christian Heimesc94e2b52008-01-14 04:13:37 +00006160- sys.float_info / PyFloat_GetInfo: The floating point information

6162
Georg Brandl3ee81df2008-05-17 18:14:43 +00006163- Patch #1816: Added sys.flags structseq. It exposes the status of
6164 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006182- Improve some exception messages when Windows fails to load an
6183 extension module. Now we get for example '%1 is not a valid Win32
6184 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006191- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006192 and INF. float("nan"), float("inf") and float("-inf") now work on
6193 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006195- Compiler now generates simpler and faster code for dictionary
6196 literals. The oparg for BUILD_MAP now indicates an estimated
6197 dictionary size. There is a new opcode, STORE_MAP, for adding
6198 entries to the dictionary.

6228 file can now be directly executed by passing their name to the
6229 interpreter. The directory/zipfile is automatically inserted as the
6230 first entry in sys.path.

6241
Georg Brandl21e99f42010-03-07 15:23:59 +00006242- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6244 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006245
Georg Brandl3ee81df2008-05-17 18:14:43 +00006246- Issue #1686386: Tuple's tp_repr did not take into account the
6247 possibility of having a self-referential tuple, which is possible
6248 from C code. Nor did object's tp_str consider that a type's tp_str
6249 could do something that could lead to an inifinite recursion.
6250 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6251 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006252
Georg Brandl3ee81df2008-05-17 18:14:43 +00006253- Issue #1164: It was possible to trigger deadlock when using the
6254 'print' statement to write to a file since the GIL was not released
6255 as needed. Now PyObject_Print() does the right thing along with
6256 various tp_print implementations of the built-in types and those in
6257 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006258
Georg Brandl3ee81df2008-05-17 18:14:43 +00006259- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006266- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006267 PyObject_Call() never calling back out to Python code to trigger
6268 recursion depth updates/checks. Required the creation of a static
6269 RuntimeError instance in case normalizing an exception put the
6270 recursion check value past its limit. Fixes crashers
6271 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006286- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287 __*__ attributes. (Some already existed, e.g., __doc__ and
6288 __name__.)

6294 calls.
6295
Collin Winter62903052007-05-18 23:11:24 +00006296- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006297 "except E as target:". This is to provide forwards compatibility
6298 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006305- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006306 setting a plain string, ie don't expand to single letter identifiers.
6307
Raymond Hettinger13936692007-04-11 18:40:58 +00006308- Request #1191699: Slices can now be pickled.
6309
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006310- Request #1193128: str.translate() now allows a None argument for
6311 translations that only remove characters without re-mapping the
6312 remaining characters.
6313
Georg Brandl5cb76c12007-03-21 09:00:39 +00006314- Patch #1682205: a TypeError while unpacking an iterable is no longer

6318
Guido van Rossum143b5642007-03-23 04:58:42 +00006319- Bug #1683368: The object.__init__() and object.__new__() methods are
6320 now stricter in rejecting excess arguments. The only time when
6321 either allows excess arguments is when it is not overridden and the
6322 other one is. For backwards compatibility, when both are
6323 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006324 warning later). Also, type.__init__() insists on the same signature
6325 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006326
Georg Brandl3ee81df2008-05-17 18:14:43 +00006327- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6328 object to complex using its __complex__() method before falling back
6329 to the __float__() method. Therefore, the functions in the cmath
6330 module now can operate on objects that define a __complex__()
6331 method.

6342 its type.

6348
Georg Brandl7b9c5552007-03-12 14:30:05 +00006349- Bug #1678647: write a newline after printing an exception in any
6350 case, even when converting the value to a string failed.
6351
Georg Brandl871f1bc2007-03-12 13:17:36 +00006352- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353 its argument, if it exists. If not, it will work like before. This
6354 allows customizing the output of dir() in the presence of a
6355 __getattr__().

6364 parthensized forms. This means complex(repr(x)) now works instead of
6365 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006366
Georg Brandlaa2321b2007-03-07 00:40:28 +00006367- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368 makes the filenames the warning module prints much more sensible
6369 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006382- Patch #1674228: when assigning a slice (old-style), check for the
6383 sq_ass_slice instead of the sq_slice slot.
6384
Georg Brandl3ee81df2008-05-17 18:14:43 +00006385- When printing an unraisable error, don't print exceptions. before
6386 the name. This duplicates the behavior whening normally printing
6387 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006955 are set for invalid interpolation sequences that would lead to

7012 TestCase and TestSuite subclasses (not instances) are no longer
7013 accepted in TestSuite.addTest(). This should cause no

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007303 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007305 does not claim to support starttls. Adds the
7306 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007405 time so that opening a database previously created with the DB_DUP
7406 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7407 opens. Specifically: dictionary assignment to a DB object will
7408 replace all values for a given key when the database allows
7409 duplicate values. DB users should use DB.put(k, v) when they want
7410 to store duplicates; not DB[k] = v.

7766 of w# format code incorrectly truncated the length to an int, even
7767 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7768 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7795 absolute imports. In earlier versions they might have used relative
7796 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007797
Georg Brandl3ee81df2008-05-17 18:14:43 +00007798- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7799 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007800
