Ned Deily18fae3f2013-01-31 01:24:55 -0800944- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
945 In particular, fix extension module build failures when trying to use
946 32-bit-only installer Pythons on systems with Xcode 4 (currently
947 OS X 10.8, 10.7, and optionally 10.6).
948 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
949 * Since Xcode 4 removes ppc support, extension module builds now
950 check for ppc compiler support and by default remove ppc and
951 ppc64 archs when they are not available.
952 * Extension module builds now revert to using system installed
953 headers and libs (/usr and /System/Library) if the SDK used
954 to build the interpreter is not installed or has moved.
955 * Try to avoid building extension modules with deprecated
956 and problematic Apple llvm-gcc compiler. If original compiler
957 is not available, use clang instead by default.

1309 int.__pow__. These overflow checks were causing int.__pow__ to produce
1310 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001311 compiler optimizing the check away. Also fix similar overflow checks
1312 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1325 cleared by the garbage collector. This fixes a segfault when an instance
1326 and its type get caught in a reference cycle, and the instance's
1327 deallocator calls one of the methods on the type (e.g. when subclassing
1328 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01001381- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001382 has left two versions of customize_compiler, the original in
1383 distutils.sysconfig and another copy in distutils.ccompiler, with some
1384 parts of distutils calling one and others using the other.

1386 is the case in 3.x.
1387
Ned Deily0d0ea482012-02-10 12:59:06 +01001388- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1389 Distutils-based packages with C extension modules may fail because
1390 Apple has removed gcc-4.2, the version used to build python.org
1391 64-bit/32-bit Pythons. If the user does not explicitly override
1392 the default C compiler by setting the CC environment variable,
1393 Distutils will now attempt to compile extension modules with clang
1394 if gcc-4.2 is required but not found. Also as a convenience, if
1395 the user does explicitly set CC, substitute its value as the default
1396 compiler in the Distutils LDSHARED configuration variable for OS X.
1397 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1398 SDK, neither of which are available in Xcode 4. This change does not
1399 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001649- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1650 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1651 interpreter process. This could cause failures in non-Distutils subprocesses
1652 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001653 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001654 deployment target only in the environment of each build subprocess. It is
1655 still possible to globally override the default by setting
1656 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1657 greater or equal to the default value, the value with which the interpreter
1658 was built.

1685
Barry Warsawc5643282011-07-19 17:06:30 -04001686- sys.setcheckinterval() now updates the current ticker count as well as
1687 updating the check interval, so if the user decreases the check interval,
1688 the ticker doesn't have to wind down to zero from the old starting point
1689 before the new interval takes effect. And if the user increases the
1690 interval, it makes sure the new limit takes effect right away rather have an
1691 early task switch before recognizing the new interval.

Antoine Pitrou66b5df62010-09-27 18:16:46 +00002641- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
2642 received. Now sendall() properly calls signal handlers if necessary,
2643 and retries sending if these returned successfully, including on sockets
2644 with a timeout.

2658 SSLSocket.sendto() to match the corresponding socket methods. Also,
2659 fix various SSLSocket methods to raise socket.error rather than an

2661 by Andrew Bennetts.

2670
Raymond Hettinger20397532010-09-12 02:11:45 +00002671- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2672 This prevents user-created self-referencing ordered dictionaries from
2673 becoming permanently uncollectable GC garbage. The downside is that
2674 removing __del__ means that the internal doubly-linked list has to wait for
2675 GC collection rather than freeing memory immediately when the refcnt drops
2676 to zero.
2677

2684 to fetch the original errno, or to filter timeout errors. Now the
2685 original error is re-raised.

2706
R. David Murray7c4bf552010-08-25 01:45:57 +00002707- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2708 character years even if the message contains RFC822 two character years.
2709
Daniel Stutzbach91287322010-08-24 21:09:30 +00002710- Issue #8750: Fixed MutableSet's methods to correctly handle

2729
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002730- Issue #9626: the view methods for collections.OrderedDict() were returning

2739 and a BadZipfile error is raised if it doesn't match (as used to be the
2740 case in Python 2.5 and earlier).

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002742- Issue #9550: a BufferedReader could issue an additional read when the

2744 when the underlying raw IO channel was e.g. a socket. Report and original
2745 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003496 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3497 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3498 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3518Core and Builtins
3519-----------------
3520
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003521- Issue #7301: Add environment variable $PYTHONWARNINGS.
3522
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003523- Issue #8329: Don't return the same lists from select.select when no fds are
3524 changed.
3525
Georg Brandlfee0f442010-05-22 21:26:21 +00003526- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003527 on 64-bit machines. The shift count for either left or right shift is
3528 permitted to be up to sys.maxsize.
3529
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003530- Ensure that tokenization of identifiers is not affected by locale.
3531
Georg Brandlfee0f442010-05-22 21:26:21 +00003532- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003533
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003534- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3535
Georg Brandlfee0f442010-05-22 21:26:21 +00003536- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3537 with a non-empty format string. This is an effort to future-proof user
3538 code. If a derived class does not currently implement __format__ but later
3539 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003540 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003541 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003542
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003543- Issue #8268: Old-style classes (not just instances) now support weak

3552 arguments to a function correct.
3553
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003554- Issue #8164: Don't allow lambda functions to have a docstring.
3555
Victor Stinner66644262010-03-10 22:30:19 +00003556- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003557 (SIGINT). If an error occurs while importing the site module, the error is
3558 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003559 module.

3573
Georg Brandlfee0f442010-05-22 21:26:21 +00003574- Issue #8257: The Decimal construct now accepts a float instance directly,
3575 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003576
3577 >>> Decimal(1.1)
3578 Decimal('1.100000000000000088817841970012523233890533447265625')
3579
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003580- collections.Counter() now supports a subtract() method.
3581
Georg Brandlfee0f442010-05-22 21:26:21 +00003582- The functools module now has a total_ordering() class decorator to simplify
3583 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003584
Georg Brandlfee0f442010-05-22 21:26:21 +00003585- The functools module also adds cmp_to_key() as a tool to transition old-style
3586 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003587
Georg Brandlfee0f442010-05-22 21:26:21 +00003588- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3589 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003590
Georg Brandlfee0f442010-05-22 21:26:21 +00003591- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3592 InvalidOperation instead of returning False. (Comparisons involving a quiet
3593 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3594 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003595
Georg Brandlfee0f442010-05-22 21:26:21 +00003596- Issue #2531: Comparison operations between floats and Decimal instances now
3597 return a result based on the numeric values of the operands; previously they
3598 returned an arbitrary result based on the relative ordering of id(float) and
3599 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003600
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003601- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003602 argument `-` which tells it to read files to compile from stdin. Each line is
3603 read on demand and the named file is compiled immediately. (Original patch by
3604 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003605
Georg Brandlfee0f442010-05-22 21:26:21 +00003606- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003609- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3610 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003611 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003612
Georg Brandlfee0f442010-05-22 21:26:21 +00003613- Comparisons using one of <, <=, >, >= between a complex instance and a
3614 Fractions instance now raise TypeError instead of returning True/False. This
3615 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3616 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003617

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003627- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003628 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3629 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003630
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003631- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003671- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003672 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3673 log file to compute the next rollover time. If the log file does not exist,
3674 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003675

Georg Brandlfee0f442010-05-22 21:26:21 +00003723 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3724 inconsistent: __int__ was used for some integer codes but not for others, and
3725 the set of integer codes for which it was used differed between native packing
3726 and standard packing.)

3979 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3980 returning NULL. The macro now returns a statically allocated empty string
3981 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004034 file position when calling `truncate()`. It would previously change the file
4035 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004036 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4037

4039 class used to represent files stored inside an archive. The new
4040 implementation is significantly faster and can be wrapped in a
4041 ``io.BufferedReader`` object for more speedups. It also solves an issue
4042 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4043 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004052
Georg Brandlba83f822010-03-14 09:50:54 +00004053- Issue #7748: Since unicode values are supported for some metadata options in
4054 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4055 encoded string for them. This ensures that the upload and register commands
4056 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004327- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4328 decimal string that's guaranteed to round back to x under correct rounding
4329 (with round-half-to-even rounding mode). Previously it gave a string based on
4330 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4331 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4332 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004333
Georg Brandlba83f822010-03-14 09:50:54 +00004334- Issue #7117: On almost all platforms: float-to-string and string-to-float
4335 conversions within Python are now correctly rounded. Places these conversions
4336 occur include: str for floats and complex numbers; the float and complex
4337 constructors; old-style and new-style numeric formatting; serialization and
4338 deserialization of floats and complex numbers using marshal, pickle and json;
4339 parsing of float and imaginary literals in Python code; Decimal-to-float
4340 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004341
Georg Brandlba83f822010-03-14 09:50:54 +00004342 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4343 providing correctly-rounded strtod and dtoa C functions. This code is
4344 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4345 the C compiler. There may be a small number of platforms on which correct
4346 operation of this code cannot be guaranteed, so the code is not used: notably,
4347 this applies to platforms where the C double format is not IEEE 754 binary64,
4348 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4349 and Python's configure script is unable to determine how to change the FPU
4350 precision. On these platforms conversions use the platform strtod and dtoa,
4351 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004352
Georg Brandlba83f822010-03-14 09:50:54 +00004353- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4354 uses the correctly-rounded string <-> float conversions described above (when
4355 available), and so produces correctly rounded results that will display nicely
4356 under the float repr. There are two related small changes: (1) round now
4357 accepts any class with an ``__index__()`` method for its second argument (but
4358 no longer accepts floats for the second argument), and (2) an excessively
4359 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4360 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004507- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4508 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4509 but with at least one decimal point and with a default precision
4510 of 12. Previously, the behavior the same but with a default precision of 6.
4511 This more closely matches ``str()``, and reduces surprises when adding
4512 alignment flags to the empty presentation type. This also affects the new
4513 complex.__format__ in the same way.
4514
4515- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004653- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4654 existing .py counterpart, override the co_filename attributes of all code

4710
Georg Brandlba83f822010-03-14 09:50:54 +00004711- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4712 file objects with closefd=False. The file descriptor is still kept open but
4713 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004737- On windows, ``os.chdir()`` given unicode was not working if
4738 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4739 this code path is really executed because I cannot move to such directory on
4740 win2k)

4743 element is temporarily replaced with an equivalent frozenset. But the
4744 eventual KeyError would always report the empty ``frozenset()`` as the missing

4766 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4767 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4768 of using the replace error handler in PyUnicode_DecodeUTF8().
4769
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004770- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004773- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4775 gives improved memory leak detection when running under Valgrind, while taking
4776 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006002 leak-chasing test runs give sensible results. The previous method of reaping
6003 threads could return successfully while some Thread objects were still
6004 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006021- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6022 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006023 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6024 the tests if DISPLAY is defined but can't be used.

6027 regression tests in parallel, shortening the total runtime.
6028
Georg Brandlba83f822010-03-14 09:50:54 +00006029- Issue #5354: New test support function import_fresh_module() makes it easy to
6030 import both normal and optimised versions of modules. test_heapq and
6031 test_warnings have been adjusted to use it, tests for other modules with both
6032 C and Python implementations in the stdlib can be adjusted to use it over
6033 time.

Georg Brandlba83f822010-03-14 09:50:54 +00006041- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
6042 should cause a test to be skipped are now done using import_module from test
6043 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006144- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6145
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006146- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6147 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6148 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6149 ``printf`` function, whereas PyString_FromFormat has an independent
6150 implementation and uses "%zd" on all platforms for size_t values.
6151 This makes a difference on win64, where ``printf`` needs "%Id" to display
6152 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006154- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6158 object; previously an int would be returned for small values. the __long__
6159 method is allowed to return either an int or a long, but the behaviour of
6160 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006162- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006168 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006169 was correctly parsed but parsing of subsequent arguments failed.
6170
Vinay Sajip35e3b032008-09-01 14:33:59 +00006171- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006172 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6173 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6174 when given a tuple of classes as second argument, were looking up
6175 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6176 type object.
6177
Neal Norwitz18aa3882008-08-24 05:04:52 +00006178- Fix crashes on memory allocation failure found with failmalloc.

6273
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006274- Issue #2975: When compiling several extension modules with Visual Studio 2008
6275 from the same python interpreter, some environment variables would grow
6276 without limit.
6277
Benjamin Peterson37346b22008-08-23 20:27:43 +00006278- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6279 exploitation of poor argument checking.
6280
Gerhard Häringef2276b2008-09-12 13:54:06 +00006281- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

6294 wrapper for warnings.catch_warnings() that makes it easier to check
6295 that expected warning messages are being reported.
6296

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006315What's New in Python 2.6 beta 3?
6316================================
6317
Barry Warsaw07a4a382008-08-21 01:15:08 +00006318*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006319
6320Core and Builtins
6321-----------------
6322
Guido van Rossumf8402962008-08-20 15:01:50 +00006323- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6324 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6325 extensions do not automatically benefit from the class attribute
6326 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6327 to their tp_flags field if they care. This is a backwards
6328 compatibility feature; in 3.0, all types will use the cache by
6329 default.
6330
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006331- Keyword arguments can now follow starred arguments. (``f(a, *args,
6332 keyword=23)`` is now valid syntax.)
6333
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006334- ctypes function pointers that are COM methods have a boolean True
6335 value again.
6336
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006337- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6338 by denying s# to parse objects that have a releasebuffer procedure,
6339 and introducing s*.
6340
Georg Brandl1e13ea92008-08-11 09:07:59 +00006341- Issue #3537: Fix an assertion failure when an empty but presized dict
6342 object was stored in the freelist.
6343
Mark Dickinsonb6467572008-08-04 21:30:09 +00006344- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6345 ValueError consistently across platforms.
6346
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006347- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6348 (64bit Unix, for example), unichr() would truncate its argument and return
6349 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6350
Neal Norwitze7d8be82008-07-31 17:17:14 +00006351- Apply security patches from Apple.
6352
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006353- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6354 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6355
Antoine Pitrou92f82162008-07-25 22:22:08 +00006356- Issue #1819: function calls with several named parameters are now on
6357 average 35% faster (as measured by pybench).
6358
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006359- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6360 the python debugger steps into a class statement: the free variables (local
6361 variables defined in an outer scope) would be deleted from the outer scope.
6362
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006363- Issue #2620: Overflow checking when allocating or reallocating memory
6364 was not always being done properly in some python types and extension
6365 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6366 all been updated to perform better checks and places in the code that
6367 would previously leak memory on the error path when such an allocation
6368 failed have been fixed.
6369
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006370Library
6371-------
6372
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006373- Issue #3612: Added some missing basic types in ctypes.wintypes.
6374
Benjamin Petersone977ad42008-08-20 01:42:01 +00006375- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6376 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6377
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006378- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6379 version reported by these tools does not necessarily follow the python
6380 version numbering scheme, so the module is less strict when parsing it.
6381
Nick Coghlanf70385a2008-08-18 12:42:46 +00006382- Issue #2235: Added Py3k warnings for types which will become unhashable
6383 under the stricter __hash__ inheritance rules in 3.0. Several types
6384 which did not meet the rules for hash invariants and were already
6385 unhashable in 3.0 have now been explicitly flagged as unhashable in
6386 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6387 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6388
Brett Cannon88f801d2008-08-18 00:46:22 +00006389- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6390 imported into the module but exposed as part of the module's API.
6391
Brett Cannon7b96f072008-08-18 00:41:11 +00006392- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6393
Brett Cannon46225e72008-08-18 00:36:52 +00006394- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6395
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006396- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6397
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006398- Issue #3575: Incremental decoder's decode function now takes bytearray
6399 by using 's*' instead of 't#'.
6400
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006401- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006402 fails unicode conversion on 2nd parameter. (windows only)
6403
Georg Brandl222e2082010-08-01 22:27:39 +00006404- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006405 in a redirect.
6406
Brett Cannonabe423e2008-08-16 21:47:07 +00006407- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006408 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006409
Facundo Batistaeb90b782008-08-16 14:44:07 +00006410- Issue #2776: fixed small issue when handling an URL with double slash
6411 after a 302 response in the case of not going through a proxy.
6412
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006413- Issue #2676: in the email package, content-type parsing was hanging on
6414 pathological input because of quadratic or exponential behaviour of a
6415 regular expression.
6416
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006417- Issue #3476: binary buffered reading through the new "io" library is now
6418 thread-safe.
6419
Brett Cannonbf3157b2008-08-14 05:00:03 +00006420- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6421 since mimetools itself is deprecated. Because modules are cached, all
6422 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6423
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006424- Issue #3134: shutil referenced undefined WindowsError symbol.
6425
Robert Schuppenies14646332008-08-10 11:01:53 +00006426- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6427 menu entries were not deleted.
6428
Brett Cannon83e81842008-08-09 23:30:55 +00006429- Copied the implementation of reduce() to _functools.reduce() to have a
6430 version that did not raise a DeprecationWarning under -3.
6431
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006432- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6433 a MemoryError rather than silently stop the iteration.
6434
Guido van Rossum59ce9012008-08-09 14:55:34 +00006435- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6436 to _sre.compile() will now be rejected. This should not affect anybody
6437 since the re.compile() function never generates invalid re-bytecode.
6438
Skip Montanaroa032bf42008-08-08 22:52:51 +00006439- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6440 upon first access it can be automatically initialized from the csv file if
6441 it wasn't initialized during instantiation.
6442
Brett Cannon3aa2a492008-08-06 22:28:09 +00006443- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6444 the reload() built-in has been removed.
6445
Brett Cannon7e30b672008-08-04 21:52:25 +00006446- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006447 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006448 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6449 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6450 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6451 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6452 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006453
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006454- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6455 raised an AttributeError.
6456
Benjamin Peterson01a24322008-07-28 23:35:27 +00006457- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006458 asking for a specific length. This problem only affected files opened
6459 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006460
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006461- Issue #3449: Update decimal module to use most recent specification
6462 (v. 1.68) and tests (v. 2.58) from IBM.
6463
Georg Brandl222e2082010-08-01 22:27:39 +00006464- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6468
Georg Brandlf9efabb2008-07-23 15:16:45 +00006469- Deprecate the "ast" parser function aliases.
6470
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006471- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6472
6473- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6474 invalid arguments.
6475
6476- Issue #3302: Fix several crashes when calling locale's gettext functions
6477 with None arguments.
6478

6483
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006484- Issue #3394: zipfile.writestr sets external attributes when passed a
6485 file name rather than a ZipInfo instance, so files are extracted with
6486 mode 0600 rather than 000 under Unix.
6487
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006488- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6489 argument in python 2.5, this broke code that subclassed Popen to include its
6490 own poll method. Fixed my moving _deadstate to an _internal_poll method.
6491
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00006492Build
6493-----

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006497Documentation
6498-------------
6499
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006500- Issue #2235: the C API function PyObject_HashNotImplemented and its
6501 interaction with the tp_hash slot (added in 2.6b2) are now documented
6502
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006503- Issue #643841: The language reference now provides more detailed
6504 coverage of the lookup process for special methods. The disclaimers
6505 regarding lack of coverage of new-style classes have also been
6506 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006509What's New in Python 2.6 beta 2?
6510================================
6511
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006512*Release date: 17-Jul-2008*
6513
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006514Core and Builtins
6515-----------------
6516
Georg Brandl3e483f62008-07-16 22:57:41 +00006517- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6518 its methods now allow for items objects that can be converted to
6519 an integer using operator.index().
6520
Mark Dickinson64b7e502008-07-16 09:40:03 +00006521- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6522 produced a ValueError instead of giving the correct float.
6523
Eric Smitha5fa5a22008-07-16 00:11:49 +00006524- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6525 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6526
Mark Dickinson7103aa42008-07-15 19:08:33 +00006527- Issue #3008: the float type has a new instance method 'float.hex'
6528 and a new class method 'float.fromhex' to convert floating-point
6529 numbers to and from hexadecimal strings, respectively.
6530
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006531- Issue #2235: __hash__ is once again inherited by default. To allow
6532 collections.Hashable to remain meaningful in the presence of the
6533 default hash implementation (object.__hash__), it is now possible
6534 to explicit block inheritance of hash by setting __hash__=None at
6535 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6536 level.
6537
Nick Coghlanb028f502008-07-13 14:52:36 +00006538- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6539 the parent module cannot be found while performing an absolute import.
6540 This means that an incorrectly defined __package__ attribute will
6541 now only prevent relative imports in that module rather than causing
6542 all imports from that module to fail.
6543
Nick Coghlan14ff9942008-07-08 14:21:42 +00006544- Issue #2517: Allow unicode messages in Exceptions again by correctly
6545 bypassing the instance dictionary when looking up __unicode__ on
6546 new-style classes.
6547
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006548- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6549 set to a custom object whose write() method happens to install
6550 another file in sys.stdout.
6551
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006552- Issue #3088: Corrected a race condition in classes derived from
6553 threading.local: the first member set by a thread could be saved in
6554 another thread's dictionary.
6555
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006556- Issue #3004: Minor change to slice.indices(): the start and stop
6557 arguments are now treated identically, making the behaviour easier
6558 to describe and understand. For example, slice(None, -10,
6559 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6560 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6561 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00007015 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007016
7017 This is controlled by the configure argument ``--with-universal-archs``:
7018
7019 - ``--with-universal-archs=all``: install 4-way universal
7020
7021 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7022
7023 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7024

Georg Brandl3ee81df2008-05-17 18:14:43 +00007077- Issue #1631171: Re-implement the 'warnings' module in C (the
7078 original Python code has been kept as backup). This will allow for
7079 using the 'warning's machinery in such places as the parser where
7080 use of pure Python code is not possible. Both the ``showarning()``
7081 and ``formatwarning()`` gain an optional 'line' argument which is
7082 not called by default for backwards-compatibility reasons. Setting
7083 ``warnings.showwarning()`` to an implementation that lacks support
7084 for the ``line`` argument will raise a DeprecationWarning.

7108
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007109- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00007147- Issue #2550: The approach used by client/server code for obtaining
7148 ports to listen on in network-oriented tests has been refined in an
7149 effort to facilitate running multiple instances of the entire
7150 regression test suite in parallel without issue.
7151 test_support.bind_port() has been fixed such that it will always
7152 return a unique port -- which wasn't always the case with the
7153 previous implementation, especially if socket options had been set
7154 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7155 new implementation of bind_port() will actually raise an exception
7156 if it is passed an AF_INET/SOCK_STREAM socket with either the
7157 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7158 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7159 the socket it's been passed. This currently only applies to
7160 Windows. This option prevents any other sockets from binding to the
7161 host/port we've bound to, thus removing the possibility of the
7162 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7163 when a second SOCK_STREAM socket binds and accepts to a host/port
7164 that's already been bound by another socket. The optional preferred
7165 port parameter to bind_port() has been removed. Under no
7166 circumstances should tests be hard coding ports!
7167
7168 test_support.find_unused_port() has also been introduced, which will
7169 pass a temporary socket object to bind_port() in order to obtain an
7170 unused port. The temporary socket object is then closed and
7171 deleted, and the port is returned. This method should only be used
7172 for obtaining an unused port in order to pass to an external program
7173 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7174 a parameter to a server-oriented class that doesn't give you direct
7175 access to the underlying socket used.
7176
7177 Finally, test_support.HOST has been introduced, which should be used
7178 for the host argument of any relevant socket calls (i.e. bind and
7179 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007180
7181 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007183 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7184 test_asynchat and test_socket_ssl.
7185
Georg Brandl3ee81df2008-05-17 18:14:43 +00007186 It is now possible for multiple instances of the regression test
7187 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007466- Added the future_builtins module, which contains hex() and oct().
7467 These are the PEP 3127 version of these functions, designed to be
7468 compatible with the hex() and oct() builtins from Python 3.0. They
7469 differ slightly in their output formats from the existing, unchanged
7470 Python 2.6 builtins. The expected usage of the future_builtins
7471 module is:
7472 from future_builtins import hex, oct
7473
Eric Smith7ef40bf2008-02-20 23:34:22 +00007474- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7475 exponents for exponents with absolute value < 100. Follows C99
7476 standard. This is a change on Windows, which would use 3 digits.
7477 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7478 so that any alterations it does to the resulting string will be
7479 available in stringlib/formatter.h (for float.__format__).
7480
Eric Smith5a3c1352008-02-19 13:21:56 +00007481- Implemented PEP 3101, Advanced String Formatting. This adds a new
7482 builtin format(); a format() method for str and unicode; a
7483 __format__() method to object, str, unicode, int, long, float, and
7484 datetime; the class string.Formatter; and the C API
7485 PyObject_Format().
7486
Georg Brandl3ee81df2008-05-17 18:14:43 +00007487- Fixed several potential crashes, all caused by specially crafted
7488 __del__ methods exploiting objects in temporarily inconsistent
7489 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007490
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007491- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007492 prevent a possible crash: an Abstract Base Class would try to access
7493 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007494

Georg Brandl3ee81df2008-05-17 18:14:43 +00007498- Clear all free lists during a gc.collect() of the highest generation
7499 in order to allow pymalloc to free more arenas. Python may give back
7500 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007501
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502- Issue #2045: Fix an infinite recursion triggered when printing a
7503 subclass of collections.defaultdict, if its default_factory is set
7504 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007505
Christian Heimesf75dbef2008-02-08 00:11:31 +00007506- Fixed a minor memory leak in dictobject.c. The content of the free
7507 list was not freed on interpreter shutdown.
7508
Georg Brandl21e99f42010-03-07 15:23:59 +00007509- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007510 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007511
Georg Brandl3ee81df2008-05-17 18:14:43 +00007512- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7513 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007514 to compact the internal free lists of pre-allocted ints and floats.
7515
Georg Brandl3ee81df2008-05-17 18:14:43 +00007516- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7517 calls. Python expected the return type int but the fork familie
7518 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007519
Georg Brandl3ee81df2008-05-17 18:14:43 +00007520- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7521 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007522

Georg Brandl3ee81df2008-05-17 18:14:43 +00007532- Patch #1473257: generator objects gain a gi_code attribute. This is
7533 the same object as the func_code attribute of the function that
7534 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007535
Georg Brandl3ee81df2008-05-17 18:14:43 +00007536- Issue #1920: "while 0" statements were completely removed by the
7537 compiler, even in the presence of an "else" clause, which is
7538 supposed to be run when the condition is false. Now the compiler
7539 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007540
Guido van Rossumeead05f2008-01-24 18:21:02 +00007541- A few crashers fixed: weakref_in_del.py (issue #1377858);
7542 loosing_dict_ref.py (issue #1303614, test67.py);
7543 borrowed_ref_[34].py (not in tracker).
7544
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007545- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007546 suppressed while an extension is loaded by calling SetErrorMode in
7547 dynload_win.c. The error is still reported properly.
7548
Georg Brandl3ee81df2008-05-17 18:14:43 +00007549- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007550 several extension methods and modules do not work without unicode
7551 support.
7552
Georg Brandl26543b12008-01-21 18:36:51 +00007553- Issue #1882: when compiling code from a string, encoding cookies in the
7554 second line of code were not always recognized correctly.
7555
Georg Brandl14404b62008-01-19 19:27:05 +00007556- Issue #1679: "0x" was taken as a valid integer literal.
7557
Georg Brandl6caad7d2008-01-26 14:19:22 +00007558- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007559 added.
7560
Christian Heimesc94e2b52008-01-14 04:13:37 +00007561- sys.float_info / PyFloat_GetInfo: The floating point information
7562 object was converted from a dict to a specialized structseq object.
7563
Georg Brandl3ee81df2008-05-17 18:14:43 +00007564- Patch #1816: Added sys.flags structseq. It exposes the status of
7565 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007566
Georg Brandl3ee81df2008-05-17 18:14:43 +00007567- Objects/structseq.c: Implemented new structseq representation. The
7568 patch makes structseqs (e.g. the return value of os.stat) more
7569 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007570
Georg Brandl3ee81df2008-05-17 18:14:43 +00007571- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007628- Patch #1739468: Directories and zipfiles containing a __main__.py
7629 file can now be directly executed by passing their name to the
7630 interpreter. The directory/zipfile is automatically inserted as the
7631 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007633- Issue #1265: Fix a problem with sys.settrace, if the tracing
7634 function uses a generator expression when at the same time the
7635 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007636
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007637- sets and frozensets now have an isdisjoint() method.

7642
Georg Brandl21e99f42010-03-07 15:23:59 +00007643- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007644 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7645 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007646
Georg Brandl3ee81df2008-05-17 18:14:43 +00007647- Issue #1686386: Tuple's tp_repr did not take into account the
7648 possibility of having a self-referential tuple, which is possible
7649 from C code. Nor did object's tp_str consider that a type's tp_str
7650 could do something that could lead to an inifinite recursion.
7651 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7652 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007653
Georg Brandl3ee81df2008-05-17 18:14:43 +00007654- Issue #1164: It was possible to trigger deadlock when using the
7655 'print' statement to write to a file since the GIL was not released
7656 as needed. Now PyObject_Print() does the right thing along with
7657 various tp_print implementations of the built-in types and those in
7658 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Issue #1147: Exceptions were directly allowing string exceptions in

7662 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007666
Brett Cannon1e534b52007-09-07 04:18:30 +00007667- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007668 PyObject_Call() never calling back out to Python code to trigger
7669 recursion depth updates/checks. Required the creation of a static
7670 RuntimeError instance in case normalizing an exception put the
7671 recursion check value past its limit. Fixes crashers
7672 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007687- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688 __*__ attributes. (Some already existed, e.g., __doc__ and
7689 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007690
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007691- Add -3 option to the interpreter to warn about features that are
7692 deprecated and will be changed/removed in Python 3.0.
7693
Georg Brandl2134e752007-05-21 20:34:16 +00007694- Patch #1686487: you can now pass any mapping after '**' in function
7695 calls.
7696
Collin Winter62903052007-05-18 23:11:24 +00007697- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007698 "except E as target:". This is to provide forwards compatibility
7699 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007706- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007707 setting a plain string, ie don't expand to single letter identifiers.
7708
Raymond Hettinger13936692007-04-11 18:40:58 +00007709- Request #1191699: Slices can now be pickled.
7710
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007711- Request #1193128: str.translate() now allows a None argument for
7712 translations that only remove characters without re-mapping the
7713 remaining characters.
7714
Georg Brandl5cb76c12007-03-21 09:00:39 +00007715- Patch #1682205: a TypeError while unpacking an iterable is no longer

7719
Guido van Rossum143b5642007-03-23 04:58:42 +00007720- Bug #1683368: The object.__init__() and object.__new__() methods are
7721 now stricter in rejecting excess arguments. The only time when
7722 either allows excess arguments is when it is not overridden and the
7723 other one is. For backwards compatibility, when both are
7724 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007725 warning later). Also, type.__init__() insists on the same signature
7726 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007727
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7729 object to complex using its __complex__() method before falling back
7730 to the __float__() method. Therefore, the functions in the cmath
7731 module now can operate on objects that define a __complex__()
7732 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007733
Georg Brandl3ee81df2008-05-17 18:14:43 +00007734- Patch #1623563: allow __class__ assignment for classes with

7736 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007737

7743 its type.

7749
Georg Brandl7b9c5552007-03-12 14:30:05 +00007750- Bug #1678647: write a newline after printing an exception in any
7751 case, even when converting the value to a string failed.
7752
Georg Brandl871f1bc2007-03-12 13:17:36 +00007753- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007754 its argument, if it exists. If not, it will work like before. This
7755 allows customizing the output of dir() in the presence of a
7756 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007764- Patch #1491866: change the complex() constructor to allow
7765 parthensized forms. This means complex(repr(x)) now works instead of
7766 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007767
Georg Brandlaa2321b2007-03-07 00:40:28 +00007768- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769 makes the filenames the warning module prints much more sensible
7770 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007771

7773 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00007783- Patch #1674228: when assigning a slice (old-style), check for the
7784 sq_ass_slice instead of the sq_slice slot.
7785
Georg Brandl3ee81df2008-05-17 18:14:43 +00007786- When printing an unraisable error, don't print exceptions. before
7787 the name. This duplicates the behavior whening normally printing
7788 exceptions.

8354
Georg Brandl92a6bae2007-03-13 17:43:32 +00008355- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356 are set for invalid interpolation sequences that would lead to

8413 TestCase and TestSuite subclasses (not instances) are no longer
8414 accepted in TestSuite.addTest(). This should cause no
8415 incompatibility since it never made sense with ordinary subclasses
8416 -- the failure just occurred later, with a more cumbersome
8417 exception.

8695 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008696
Georg Brandl3ee81df2008-05-17 18:14:43 +00008697- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008698 that the SMTP.starttls() caller no longer needs to call ehlo()
8699 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008700 does not claim to support starttls. Adds the
8701 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8702 Fenner.

8782 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8783 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00008785

Georg Brandl3ee81df2008-05-17 18:14:43 +00008800 time so that opening a database previously created with the DB_DUP
8801 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8802 opens. Specifically: dictionary assignment to a DB object will
8803 replace all values for a given key when the database allows
8804 duplicate values. DB users should use DB.put(k, v) when they want
8805 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008806

8812 characters with ASCII value less than 32. Also, it correctly quotes
8813 dots only if they occur on a single line, as opposed to the previous
8814 behavior of quoting dots if they are the second character of any
8815 line.

Guido van Rossum7c862f82007-12-13 20:50:10 +00009087- Bug #1608: use -fwrapv when GCC supports it. This is important,
9088 newer GCC versions may optimize away overflow buffer overflow checks
9089 without this option!
9090
Martin v. Löwis63bf1492007-11-12 05:14:05 +00009091- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
9092
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009093- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009094 periodic threadstate and signal checking in tight loops. By
9095 default, this option is turned-off. It should only be enabled in
9096 debugged, performance critical applications.

9147-----
9148
Georg Brandl3ee81df2008-05-17 18:14:43 +00009149- Unified naming convention for free lists and their limits. All free
9150 lists in Object/ are named ``free_list``, the counter ``numfree``
9151 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9152 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9155 to ``PyTuple_SetItem``, it can be used to populate a brand new
9156 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009157

9165
9166- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9167 ``PyFloat_GetInfo()`` to the float API.
9168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9170 of w# format code incorrectly truncated the length to an int, even
9171 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9172 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009173
Georg Brandl3ee81df2008-05-17 18:14:43 +00009174- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9192- Fix some leftovers from the conversion from int to Py_ssize_t
9193 (relevant to strings and sequences of more than 2**31 items).
9194
9195- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9196 outside of pystate.c and should not be necessary.
9197
Georg Brandl3ee81df2008-05-17 18:14:43 +00009198- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9199 absolute imports. In earlier versions they might have used relative
9200 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009201
Georg Brandl3ee81df2008-05-17 18:14:43 +00009202- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9203 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009204
Georg Brandl3ee81df2008-05-17 18:14:43 +00009205- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

9213 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9214 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9215 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009216

Georg Brandl3ee81df2008-05-17 18:14:43 +00009230- Removed the macfs module. It had been deprecated since Python 2.5.
9231 This lead to the deprecation of macostools.touched() as it relied
9232 solely on macfs and was a no-op under OS X.
