Ned Deily18fae3f2013-01-31 01:24:55 -0800941- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
942 In particular, fix extension module build failures when trying to use
943 32-bit-only installer Pythons on systems with Xcode 4 (currently
944 OS X 10.8, 10.7, and optionally 10.6).
945 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
946 * Since Xcode 4 removes ppc support, extension module builds now
947 check for ppc compiler support and by default remove ppc and
948 ppc64 archs when they are not available.
949 * Extension module builds now revert to using system installed
950 headers and libs (/usr and /System/Library) if the SDK used
951 to build the interpreter is not installed or has moved.
952 * Try to avoid building extension modules with deprecated
953 and problematic Apple llvm-gcc compiler. If original compiler
954 is not available, use clang instead by default.

1306 int.__pow__. These overflow checks were causing int.__pow__ to produce
1307 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001308 compiler optimizing the check away. Also fix similar overflow checks
1309 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1322 cleared by the garbage collector. This fixes a segfault when an instance
1323 and its type get caught in a reference cycle, and the instance's
1324 deallocator calls one of the methods on the type (e.g. when subclassing
1325 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01001378- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001379 has left two versions of customize_compiler, the original in
1380 distutils.sysconfig and another copy in distutils.ccompiler, with some
1381 parts of distutils calling one and others using the other.
1382 Complete the revert back to only having one in distutils.sysconfig as
1383 is the case in 3.x.
1384
Ned Deily0d0ea482012-02-10 12:59:06 +01001385- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1386 Distutils-based packages with C extension modules may fail because
1387 Apple has removed gcc-4.2, the version used to build python.org
1388 64-bit/32-bit Pythons. If the user does not explicitly override
1389 the default C compiler by setting the CC environment variable,
1390 Distutils will now attempt to compile extension modules with clang
1391 if gcc-4.2 is required but not found. Also as a convenience, if
1392 the user does explicitly set CC, substitute its value as the default
1393 compiler in the Distutils LDSHARED configuration variable for OS X.
1394 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1395 SDK, neither of which are available in Xcode 4. This change does not
1396 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001646- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1647 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1648 interpreter process. This could cause failures in non-Distutils subprocesses
1649 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001650 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001651 deployment target only in the environment of each build subprocess. It is
1652 still possible to globally override the default by setting
1653 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1654 greater or equal to the default value, the value with which the interpreter
1655 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001683- sys.setcheckinterval() now updates the current ticker count as well as
1684 updating the check interval, so if the user decreases the check interval,
1685 the ticker doesn't have to wind down to zero from the old starting point
1686 before the new interval takes effect. And if the user increases the
1687 interval, it makes sure the new limit takes effect right away rather have an
1688 early task switch before recognizing the new interval.

Antoine Pitrou66b5df62010-09-27 18:16:46 +00002638- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
2639 received. Now sendall() properly calls signal handlers if necessary,
2640 and retries sending if these returned successfully, including on sockets
2641 with a timeout.

Antoine Pitrouf7f390a2010-09-14 14:37:18 +00002654- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
2655 SSLSocket.sendto() to match the corresponding socket methods. Also,
2656 fix various SSLSocket methods to raise socket.error rather than an

2658 by Andrew Bennetts.

2667
Raymond Hettinger20397532010-09-12 02:11:45 +00002668- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2669 This prevents user-created self-referencing ordered dictionaries from
2670 becoming permanently uncollectable GC garbage. The downside is that
2671 removing __del__ means that the internal doubly-linked list has to wait for
2672 GC collection rather than freeing memory immediately when the refcnt drops
2673 to zero.
2674

2681 to fetch the original errno, or to filter timeout errors. Now the
2682 original error is re-raised.

2702 falling into recursion.
2703
R. David Murray7c4bf552010-08-25 01:45:57 +00002704- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2705 character years even if the message contains RFC822 two character years.
2706
Daniel Stutzbach91287322010-08-24 21:09:30 +00002707- Issue #8750: Fixed MutableSet's methods to correctly handle

2726
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002727- Issue #9626: the view methods for collections.OrderedDict() were returning

2736 and a BadZipfile error is raised if it doesn't match (as used to be the
2737 case in Python 2.5 and earlier).
2738
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002739- Issue #9550: a BufferedReader could issue an additional read when the
2740 original read request had been satisfied, which could block indefinitely
2741 when the underlying raw IO channel was e.g. a socket. Report and original
2742 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003493 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3494 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3495 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3515Core and Builtins
3516-----------------
3517
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003518- Issue #7301: Add environment variable $PYTHONWARNINGS.
3519
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003520- Issue #8329: Don't return the same lists from select.select when no fds are
3521 changed.
3522
Georg Brandlfee0f442010-05-22 21:26:21 +00003523- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003524 on 64-bit machines. The shift count for either left or right shift is
3525 permitted to be up to sys.maxsize.
3526
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003527- Ensure that tokenization of identifiers is not affected by locale.
3528
Georg Brandlfee0f442010-05-22 21:26:21 +00003529- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003530
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003531- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3532
Georg Brandlfee0f442010-05-22 21:26:21 +00003533- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3534 with a non-empty format string. This is an effort to future-proof user
3535 code. If a derived class does not currently implement __format__ but later
3536 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003537 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003538 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003539
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003540- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003551- Issue #8164: Don't allow lambda functions to have a docstring.
3552
Victor Stinner66644262010-03-10 22:30:19 +00003553- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003554 (SIGINT). If an error occurs while importing the site module, the error is
3555 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003556 module.

3570
Georg Brandlfee0f442010-05-22 21:26:21 +00003571- Issue #8257: The Decimal construct now accepts a float instance directly,
3572 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003573
3574 >>> Decimal(1.1)
3575 Decimal('1.100000000000000088817841970012523233890533447265625')
3576
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003577- collections.Counter() now supports a subtract() method.
3578
Georg Brandlfee0f442010-05-22 21:26:21 +00003579- The functools module now has a total_ordering() class decorator to simplify
3580 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003581
Georg Brandlfee0f442010-05-22 21:26:21 +00003582- The functools module also adds cmp_to_key() as a tool to transition old-style
3583 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003584
Georg Brandlfee0f442010-05-22 21:26:21 +00003585- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3586 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003587
Georg Brandlfee0f442010-05-22 21:26:21 +00003588- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3589 InvalidOperation instead of returning False. (Comparisons involving a quiet
3590 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3591 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003592
Georg Brandlfee0f442010-05-22 21:26:21 +00003593- Issue #2531: Comparison operations between floats and Decimal instances now
3594 return a result based on the numeric values of the operands; previously they
3595 returned an arbitrary result based on the relative ordering of id(float) and
3596 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003597
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003598- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003599 argument `-` which tells it to read files to compile from stdin. Each line is
3600 read on demand and the named file is compiled immediately. (Original patch by
3601 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003602
Georg Brandlfee0f442010-05-22 21:26:21 +00003603- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003606- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3607 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003608 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003609
Georg Brandlfee0f442010-05-22 21:26:21 +00003610- Comparisons using one of <, <=, >, >= between a complex instance and a
3611 Fractions instance now raise TypeError instead of returning True/False. This
3612 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3613 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003614

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003624- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003625 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3626 silenced.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003668- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003669 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3670 log file to compute the next rollover time. If the log file does not exist,
3671 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003672

3722 the set of integer codes for which it was used differed between native packing
3723 and standard packing.)

3976 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3977 returning NULL. The macro now returns a statically allocated empty string
3978 instead.

3988 strings,
3989 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Georg Brandlba83f822010-03-14 09:50:54 +00004024 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004030- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004031 file position when calling `truncate()`. It would previously change the file
4032 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004033 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4034
Georg Brandlba83f822010-03-14 09:50:54 +00004035- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4036 class used to represent files stored inside an archive. The new
4037 implementation is significantly faster and can be wrapped in a
4038 ``io.BufferedReader`` object for more speedups. It also solves an issue
4039 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4040 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004049
Georg Brandlba83f822010-03-14 09:50:54 +00004050- Issue #7748: Since unicode values are supported for some metadata options in
4051 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4052 encoded string for them. This ensures that the upload and register commands
4053 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004130- The ``__complex__()`` method is now looked up on the class of instances to
4131 make it consistent with other special methods.

4138 These functions and methods now raise TypeError instead. The majority of the
4139 effects of this change are in the extension modules, but some core functions
4140 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4141 and many unicode/str methods.

4157 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004324- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4325 decimal string that's guaranteed to round back to x under correct rounding
4326 (with round-half-to-even rounding mode). Previously it gave a string based on
4327 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4328 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4329 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004330
Georg Brandlba83f822010-03-14 09:50:54 +00004331- Issue #7117: On almost all platforms: float-to-string and string-to-float
4332 conversions within Python are now correctly rounded. Places these conversions
4333 occur include: str for floats and complex numbers; the float and complex
4334 constructors; old-style and new-style numeric formatting; serialization and
4335 deserialization of floats and complex numbers using marshal, pickle and json;
4336 parsing of float and imaginary literals in Python code; Decimal-to-float
4337 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004338
Georg Brandlba83f822010-03-14 09:50:54 +00004339 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4340 providing correctly-rounded strtod and dtoa C functions. This code is
4341 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4342 the C compiler. There may be a small number of platforms on which correct
4343 operation of this code cannot be guaranteed, so the code is not used: notably,
4344 this applies to platforms where the C double format is not IEEE 754 binary64,
4345 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4346 and Python's configure script is unable to determine how to change the FPU
4347 precision. On these platforms conversions use the platform strtod and dtoa,
4348 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004349
Georg Brandlba83f822010-03-14 09:50:54 +00004350- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4351 uses the correctly-rounded string <-> float conversions described above (when
4352 available), and so produces correctly rounded results that will display nicely
4353 under the float repr. There are two related small changes: (1) round now
4354 accepts any class with an ``__index__()`` method for its second argument (but
4355 no longer accepts floats for the second argument), and (2) an excessively
4356 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4357 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004504- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4505 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4506 but with at least one decimal point and with a default precision
4507 of 12. Previously, the behavior the same but with a default precision of 6.
4508 This more closely matches ``str()``, and reduces surprises when adding
4509 alignment flags to the empty presentation type. This also affects the new
4510 complex.__format__ in the same way.
4511

Georg Brandlba83f822010-03-14 09:50:54 +00004650- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4651 existing .py counterpart, override the co_filename attributes of all code

4707
Georg Brandlba83f822010-03-14 09:50:54 +00004708- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4709 file objects with closefd=False. The file descriptor is still kept open but
4710 the file object behaves like a closed file. The ``FileIO`` object also got a
4711 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00004734- On windows, ``os.chdir()`` given unicode was not working if
4735 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4736 this code path is really executed because I cannot move to such directory on
4737 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004739- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4740 element is temporarily replaced with an equivalent frozenset. But the
4741 eventual KeyError would always report the empty ``frozenset()`` as the missing

4763 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4764 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4765 of using the replace error handler in PyUnicode_DecodeUTF8().
4766
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004767- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004770- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4772 gives improved memory leak detection when running under Valgrind, while taking
4773 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005999 leak-chasing test runs give sensible results. The previous method of reaping
6000 threads could return successfully while some Thread objects were still
6001 referenced. This also introduces a new private function: ``thread._count()``.

6019 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006020 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6021 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006026- Issue #5354: New test support function import_fresh_module() makes it easy to
6027 import both normal and optimised versions of modules. test_heapq and
6028 test_warnings have been adjusted to use it, tests for other modules with both
6029 C and Python implementations in the stdlib can be adjusted to use it over
6030 time.

Georg Brandlba83f822010-03-14 09:50:54 +00006038- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
6039 should cause a test to be skipped are now done using import_module from test
6040 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006141- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6142
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006143- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6144 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6145 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6146 ``printf`` function, whereas PyString_FromFormat has an independent
6147 implementation and uses "%zd" on all platforms for size_t values.
6148 This makes a difference on win64, where ``printf`` needs "%Id" to display
6149 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006151- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6155 object; previously an int would be returned for small values. the __long__
6156 method is allowed to return either an int or a long, but the behaviour of
6157 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006165 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006166 was correctly parsed but parsing of subsequent arguments failed.
6167
Vinay Sajip35e3b032008-09-01 14:33:59 +00006168- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006169 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6170 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6171 when given a tuple of classes as second argument, were looking up
6172 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6173 type object.
6174
Neal Norwitz18aa3882008-08-24 05:04:52 +00006175- Fix crashes on memory allocation failure found with failmalloc.

6270
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006271- Issue #2975: When compiling several extension modules with Visual Studio 2008
6272 from the same python interpreter, some environment variables would grow
6273 without limit.
6274
Benjamin Peterson37346b22008-08-23 20:27:43 +00006275- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6276 exploitation of poor argument checking.
6277
Gerhard Häringef2276b2008-09-12 13:54:06 +00006278- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
6279
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00006280- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
6281 remaining ones have "pysqlite_" prefix.
6282
Gerhard Häringe6872eb2008-09-12 22:33:22 +00006283- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00006290- Issue #3781: Add test.test_support.check_warnings() as a convenience
6291 wrapper for warnings.catch_warnings() that makes it easier to check
6292 that expected warning messages are being reported.
6293
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00006294- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006312What's New in Python 2.6 beta 3?
6313================================
6314
Barry Warsaw07a4a382008-08-21 01:15:08 +00006315*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006316
6317Core and Builtins
6318-----------------
6319
Guido van Rossumf8402962008-08-20 15:01:50 +00006320- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6321 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6322 extensions do not automatically benefit from the class attribute
6323 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6324 to their tp_flags field if they care. This is a backwards
6325 compatibility feature; in 3.0, all types will use the cache by
6326 default.
6327
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006328- Keyword arguments can now follow starred arguments. (``f(a, *args,
6329 keyword=23)`` is now valid syntax.)
6330
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006331- ctypes function pointers that are COM methods have a boolean True
6332 value again.
6333
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006334- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6335 by denying s# to parse objects that have a releasebuffer procedure,
6336 and introducing s*.
6337
Georg Brandl1e13ea92008-08-11 09:07:59 +00006338- Issue #3537: Fix an assertion failure when an empty but presized dict
6339 object was stored in the freelist.
6340
Mark Dickinsonb6467572008-08-04 21:30:09 +00006341- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6342 ValueError consistently across platforms.
6343
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006344- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6345 (64bit Unix, for example), unichr() would truncate its argument and return
6346 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6347
Neal Norwitze7d8be82008-07-31 17:17:14 +00006348- Apply security patches from Apple.
6349
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006350- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6351 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6352
Antoine Pitrou92f82162008-07-25 22:22:08 +00006353- Issue #1819: function calls with several named parameters are now on
6354 average 35% faster (as measured by pybench).
6355
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006356- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6357 the python debugger steps into a class statement: the free variables (local
6358 variables defined in an outer scope) would be deleted from the outer scope.
6359
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006360- Issue #2620: Overflow checking when allocating or reallocating memory
6361 was not always being done properly in some python types and extension
6362 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6363 all been updated to perform better checks and places in the code that
6364 would previously leak memory on the error path when such an allocation
6365 failed have been fixed.
6366
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006367Library
6368-------
6369
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006370- Issue #3612: Added some missing basic types in ctypes.wintypes.
6371
Benjamin Petersone977ad42008-08-20 01:42:01 +00006372- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6373 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6374
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006375- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6376 version reported by these tools does not necessarily follow the python
6377 version numbering scheme, so the module is less strict when parsing it.
6378
Nick Coghlanf70385a2008-08-18 12:42:46 +00006379- Issue #2235: Added Py3k warnings for types which will become unhashable
6380 under the stricter __hash__ inheritance rules in 3.0. Several types
6381 which did not meet the rules for hash invariants and were already
6382 unhashable in 3.0 have now been explicitly flagged as unhashable in
6383 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6384 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6385
Brett Cannon88f801d2008-08-18 00:46:22 +00006386- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6387 imported into the module but exposed as part of the module's API.
6388
Brett Cannon7b96f072008-08-18 00:41:11 +00006389- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6390
Brett Cannon46225e72008-08-18 00:36:52 +00006391- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6392
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006393- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6394
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006395- Issue #3575: Incremental decoder's decode function now takes bytearray
6396 by using 's*' instead of 't#'.
6397
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006398- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006399 fails unicode conversion on 2nd parameter. (windows only)
6400
Georg Brandl222e2082010-08-01 22:27:39 +00006401- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006402 in a redirect.
6403
Brett Cannonabe423e2008-08-16 21:47:07 +00006404- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006405 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006406
Facundo Batistaeb90b782008-08-16 14:44:07 +00006407- Issue #2776: fixed small issue when handling an URL with double slash
6408 after a 302 response in the case of not going through a proxy.
6409
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006410- Issue #2676: in the email package, content-type parsing was hanging on
6411 pathological input because of quadratic or exponential behaviour of a
6412 regular expression.
6413
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006414- Issue #3476: binary buffered reading through the new "io" library is now
6415 thread-safe.
6416
Brett Cannonbf3157b2008-08-14 05:00:03 +00006417- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6418 since mimetools itself is deprecated. Because modules are cached, all
6419 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6420
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006421- Issue #3134: shutil referenced undefined WindowsError symbol.
6422
Robert Schuppenies14646332008-08-10 11:01:53 +00006423- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6424 menu entries were not deleted.
6425
Brett Cannon83e81842008-08-09 23:30:55 +00006426- Copied the implementation of reduce() to _functools.reduce() to have a
6427 version that did not raise a DeprecationWarning under -3.
6428
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006429- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6430 a MemoryError rather than silently stop the iteration.
6431
Guido van Rossum59ce9012008-08-09 14:55:34 +00006432- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6433 to _sre.compile() will now be rejected. This should not affect anybody
6434 since the re.compile() function never generates invalid re-bytecode.
6435
Skip Montanaroa032bf42008-08-08 22:52:51 +00006436- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6437 upon first access it can be automatically initialized from the csv file if
6438 it wasn't initialized during instantiation.
6439
Brett Cannon3aa2a492008-08-06 22:28:09 +00006440- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6441 the reload() built-in has been removed.
6442
Brett Cannon7e30b672008-08-04 21:52:25 +00006443- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006444 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006445 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6446 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6447 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6448 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6449 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006450
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006451- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6452 raised an AttributeError.
6453
Benjamin Peterson01a24322008-07-28 23:35:27 +00006454- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006455 asking for a specific length. This problem only affected files opened
6456 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006457
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006458- Issue #3449: Update decimal module to use most recent specification
6459 (v. 1.68) and tests (v. 2.58) from IBM.
6460
Georg Brandl222e2082010-08-01 22:27:39 +00006461- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006462

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006464 on a closed shelf.
6465
Georg Brandlf9efabb2008-07-23 15:16:45 +00006466- Deprecate the "ast" parser function aliases.
6467
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006468- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6469
6470- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6471 invalid arguments.
6472
6473- Issue #3302: Fix several crashes when calling locale's gettext functions
6474 with None arguments.
6475
6476- Issue #3389: Allow resolving dotted names for handlers in logging
6477 configuration files.
6478

6480
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006481- Issue #3394: zipfile.writestr sets external attributes when passed a
6482 file name rather than a ZipInfo instance, so files are extracted with
6483 mode 0600 rather than 000 under Unix.
6484
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006485- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6486 argument in python 2.5, this broke code that subclassed Popen to include its
6487 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6495-------------
6496
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006497- Issue #2235: the C API function PyObject_HashNotImplemented and its
6498 interaction with the tp_hash slot (added in 2.6b2) are now documented
6499
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006500- Issue #643841: The language reference now provides more detailed
6501 coverage of the lookup process for special methods. The disclaimers
6502 regarding lack of coverage of new-style classes have also been
6503 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006506What's New in Python 2.6 beta 2?
6507================================
6508
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006509*Release date: 17-Jul-2008*
6510
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006511Core and Builtins
6512-----------------
6513
Georg Brandl3e483f62008-07-16 22:57:41 +00006514- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6515 its methods now allow for items objects that can be converted to
6516 an integer using operator.index().
6517
Mark Dickinson64b7e502008-07-16 09:40:03 +00006518- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6519 produced a ValueError instead of giving the correct float.
6520
Eric Smitha5fa5a22008-07-16 00:11:49 +00006521- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6522 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6523
Mark Dickinson7103aa42008-07-15 19:08:33 +00006524- Issue #3008: the float type has a new instance method 'float.hex'
6525 and a new class method 'float.fromhex' to convert floating-point
6526 numbers to and from hexadecimal strings, respectively.
6527
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006528- Issue #2235: __hash__ is once again inherited by default. To allow
6529 collections.Hashable to remain meaningful in the presence of the
6530 default hash implementation (object.__hash__), it is now possible
6531 to explicit block inheritance of hash by setting __hash__=None at
6532 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6533 level.
6534
Nick Coghlanb028f502008-07-13 14:52:36 +00006535- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6536 the parent module cannot be found while performing an absolute import.
6537 This means that an incorrectly defined __package__ attribute will
6538 now only prevent relative imports in that module rather than causing
6539 all imports from that module to fail.
6540
Nick Coghlan14ff9942008-07-08 14:21:42 +00006541- Issue #2517: Allow unicode messages in Exceptions again by correctly
6542 bypassing the instance dictionary when looking up __unicode__ on
6543 new-style classes.
6544
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006545- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6546 set to a custom object whose write() method happens to install
6547 another file in sys.stdout.
6548
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006549- Issue #3088: Corrected a race condition in classes derived from
6550 threading.local: the first member set by a thread could be saved in
6551 another thread's dictionary.
6552
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006553- Issue #3004: Minor change to slice.indices(): the start and stop
6554 arguments are now treated identically, making the behaviour easier
6555 to describe and understand. For example, slice(None, -10,
6556 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6557 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6558 10, -1).

7011 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007012 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007013
7014 This is controlled by the configure argument ``--with-universal-archs``:
7015
7016 - ``--with-universal-archs=all``: install 4-way universal
7017
7018 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7019
7020 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7021
7022 This option should be used in combination with ``--enable-universalsdk=``.

7061 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007074- Issue #1631171: Re-implement the 'warnings' module in C (the
7075 original Python code has been kept as backup). This will allow for
7076 using the 'warning's machinery in such places as the parser where
7077 use of pure Python code is not possible. Both the ``showarning()``
7078 and ``formatwarning()`` gain an optional 'line' argument which is
7079 not called by default for backwards-compatibility reasons. Setting
7080 ``warnings.showwarning()`` to an implementation that lacks support
7081 for the ``line`` argument will raise a DeprecationWarning.

7105
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007106- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00007144- Issue #2550: The approach used by client/server code for obtaining
7145 ports to listen on in network-oriented tests has been refined in an
7146 effort to facilitate running multiple instances of the entire
7147 regression test suite in parallel without issue.
7148 test_support.bind_port() has been fixed such that it will always
7149 return a unique port -- which wasn't always the case with the
7150 previous implementation, especially if socket options had been set
7151 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7152 new implementation of bind_port() will actually raise an exception
7153 if it is passed an AF_INET/SOCK_STREAM socket with either the
7154 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7155 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7156 the socket it's been passed. This currently only applies to
7157 Windows. This option prevents any other sockets from binding to the
7158 host/port we've bound to, thus removing the possibility of the
7159 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7160 when a second SOCK_STREAM socket binds and accepts to a host/port
7161 that's already been bound by another socket. The optional preferred
7162 port parameter to bind_port() has been removed. Under no
7163 circumstances should tests be hard coding ports!
7164
7165 test_support.find_unused_port() has also been introduced, which will
7166 pass a temporary socket object to bind_port() in order to obtain an
7167 unused port. The temporary socket object is then closed and
7168 deleted, and the port is returned. This method should only be used
7169 for obtaining an unused port in order to pass to an external program
7170 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7171 a parameter to a server-oriented class that doesn't give you direct
7172 access to the underlying socket used.
7173
7174 Finally, test_support.HOST has been introduced, which should be used
7175 for the host argument of any relevant socket calls (i.e. bind and
7176 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007177
7178 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007179 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007180 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7181 test_asynchat and test_socket_ssl.
7182
Georg Brandl3ee81df2008-05-17 18:14:43 +00007183 It is now possible for multiple instances of the regression test
7184 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007463- Added the future_builtins module, which contains hex() and oct().
7464 These are the PEP 3127 version of these functions, designed to be
7465 compatible with the hex() and oct() builtins from Python 3.0. They
7466 differ slightly in their output formats from the existing, unchanged
7467 Python 2.6 builtins. The expected usage of the future_builtins
7468 module is:
7469 from future_builtins import hex, oct
7470
Eric Smith7ef40bf2008-02-20 23:34:22 +00007471- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7472 exponents for exponents with absolute value < 100. Follows C99
7473 standard. This is a change on Windows, which would use 3 digits.
7474 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7475 so that any alterations it does to the resulting string will be
7476 available in stringlib/formatter.h (for float.__format__).
7477
Eric Smith5a3c1352008-02-19 13:21:56 +00007478- Implemented PEP 3101, Advanced String Formatting. This adds a new
7479 builtin format(); a format() method for str and unicode; a
7480 __format__() method to object, str, unicode, int, long, float, and
7481 datetime; the class string.Formatter; and the C API
7482 PyObject_Format().
7483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Fixed several potential crashes, all caused by specially crafted
7485 __del__ methods exploiting objects in temporarily inconsistent
7486 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007487
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007488- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007489 prevent a possible crash: an Abstract Base Class would try to access
7490 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007495- Clear all free lists during a gc.collect() of the highest generation
7496 in order to allow pymalloc to free more arenas. Python may give back
7497 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007498
Georg Brandl3ee81df2008-05-17 18:14:43 +00007499- Issue #2045: Fix an infinite recursion triggered when printing a
7500 subclass of collections.defaultdict, if its default_factory is set
7501 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007502
Christian Heimesf75dbef2008-02-08 00:11:31 +00007503- Fixed a minor memory leak in dictobject.c. The content of the free
7504 list was not freed on interpreter shutdown.
7505
Georg Brandl21e99f42010-03-07 15:23:59 +00007506- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007507 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007508
Georg Brandl3ee81df2008-05-17 18:14:43 +00007509- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7510 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007511 to compact the internal free lists of pre-allocted ints and floats.
7512
Georg Brandl3ee81df2008-05-17 18:14:43 +00007513- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7514 calls. Python expected the return type int but the fork familie
7515 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007516
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7518 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007519

Georg Brandl3ee81df2008-05-17 18:14:43 +00007529- Patch #1473257: generator objects gain a gi_code attribute. This is
7530 the same object as the func_code attribute of the function that
7531 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007532
Georg Brandl3ee81df2008-05-17 18:14:43 +00007533- Issue #1920: "while 0" statements were completely removed by the
7534 compiler, even in the presence of an "else" clause, which is
7535 supposed to be run when the condition is false. Now the compiler
7536 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007537
Guido van Rossumeead05f2008-01-24 18:21:02 +00007538- A few crashers fixed: weakref_in_del.py (issue #1377858);
7539 loosing_dict_ref.py (issue #1303614, test67.py);
7540 borrowed_ref_[34].py (not in tracker).
7541
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007542- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007543 suppressed while an extension is loaded by calling SetErrorMode in
7544 dynload_win.c. The error is still reported properly.
7545
Georg Brandl3ee81df2008-05-17 18:14:43 +00007546- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007547 several extension methods and modules do not work without unicode
7548 support.
7549
Georg Brandl26543b12008-01-21 18:36:51 +00007550- Issue #1882: when compiling code from a string, encoding cookies in the
7551 second line of code were not always recognized correctly.
7552
Georg Brandl14404b62008-01-19 19:27:05 +00007553- Issue #1679: "0x" was taken as a valid integer literal.
7554
Georg Brandl6caad7d2008-01-26 14:19:22 +00007555- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007556 added.
7557
Christian Heimesc94e2b52008-01-14 04:13:37 +00007558- sys.float_info / PyFloat_GetInfo: The floating point information
7559 object was converted from a dict to a specialized structseq object.
7560
Georg Brandl3ee81df2008-05-17 18:14:43 +00007561- Patch #1816: Added sys.flags structseq. It exposes the status of
7562 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007563
Georg Brandl3ee81df2008-05-17 18:14:43 +00007564- Objects/structseq.c: Implemented new structseq representation. The
7565 patch makes structseqs (e.g. the return value of os.stat) more
7566 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007567
Georg Brandl3ee81df2008-05-17 18:14:43 +00007568- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007625- Patch #1739468: Directories and zipfiles containing a __main__.py
7626 file can now be directly executed by passing their name to the
7627 interpreter. The directory/zipfile is automatically inserted as the
7628 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007630- Issue #1265: Fix a problem with sys.settrace, if the tracing
7631 function uses a generator expression when at the same time the
7632 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007633
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007634- sets and frozensets now have an isdisjoint() method.

7639
Georg Brandl21e99f42010-03-07 15:23:59 +00007640- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007641 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7642 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007643
Georg Brandl3ee81df2008-05-17 18:14:43 +00007644- Issue #1686386: Tuple's tp_repr did not take into account the
7645 possibility of having a self-referential tuple, which is possible
7646 from C code. Nor did object's tp_str consider that a type's tp_str
7647 could do something that could lead to an inifinite recursion.
7648 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7649 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007650
Georg Brandl3ee81df2008-05-17 18:14:43 +00007651- Issue #1164: It was possible to trigger deadlock when using the
7652 'print' statement to write to a file since the GIL was not released
7653 as needed. Now PyObject_Print() does the right thing along with
7654 various tp_print implementations of the built-in types and those in
7655 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007656
Georg Brandl3ee81df2008-05-17 18:14:43 +00007657- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007664- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007665 PyObject_Call() never calling back out to Python code to trigger
7666 recursion depth updates/checks. Required the creation of a static
7667 RuntimeError instance in case normalizing an exception put the
7668 recursion check value past its limit. Fixes crashers
7669 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007684- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007685 __*__ attributes. (Some already existed, e.g., __doc__ and
7686 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007687
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007688- Add -3 option to the interpreter to warn about features that are
7689 deprecated and will be changed/removed in Python 3.0.
7690
Georg Brandl2134e752007-05-21 20:34:16 +00007691- Patch #1686487: you can now pass any mapping after '**' in function
7692 calls.
7693
Collin Winter62903052007-05-18 23:11:24 +00007694- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007695 "except E as target:". This is to provide forwards compatibility
7696 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007703- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007704 setting a plain string, ie don't expand to single letter identifiers.
7705
Raymond Hettinger13936692007-04-11 18:40:58 +00007706- Request #1191699: Slices can now be pickled.
7707
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007708- Request #1193128: str.translate() now allows a None argument for

7710 remaining characters.
7711
Georg Brandl5cb76c12007-03-21 09:00:39 +00007712- Patch #1682205: a TypeError while unpacking an iterable is no longer

7716
Guido van Rossum143b5642007-03-23 04:58:42 +00007717- Bug #1683368: The object.__init__() and object.__new__() methods are
7718 now stricter in rejecting excess arguments. The only time when
7719 either allows excess arguments is when it is not overridden and the
7720 other one is. For backwards compatibility, when both are
7721 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007722 warning later). Also, type.__init__() insists on the same signature
7723 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007724
Georg Brandl3ee81df2008-05-17 18:14:43 +00007725- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7726 object to complex using its __complex__() method before falling back
7727 to the __float__() method. Therefore, the functions in the cmath
7728 module now can operate on objects that define a __complex__()
7729 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007730
Georg Brandl3ee81df2008-05-17 18:14:43 +00007731- Patch #1623563: allow __class__ assignment for classes with

7740 its type.

7746
Georg Brandl7b9c5552007-03-12 14:30:05 +00007747- Bug #1678647: write a newline after printing an exception in any
7748 case, even when converting the value to a string failed.
7749
Georg Brandl871f1bc2007-03-12 13:17:36 +00007750- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007751 its argument, if it exists. If not, it will work like before. This
7752 allows customizing the output of dir() in the presence of a
7753 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Patch #1491866: change the complex() constructor to allow
7762 parthensized forms. This means complex(repr(x)) now works instead of
7763 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007764
Georg Brandlaa2321b2007-03-07 00:40:28 +00007765- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007766 makes the filenames the warning module prints much more sensible
7767 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007780- Patch #1674228: when assigning a slice (old-style), check for the
7781 sq_ass_slice instead of the sq_slice slot.
7782
Georg Brandl3ee81df2008-05-17 18:14:43 +00007783- When printing an unraisable error, don't print exceptions. before
7784 the name. This duplicates the behavior whening normally printing
7785 exceptions.

8410 TestCase and TestSuite subclasses (not instances) are no longer
8411 accepted in TestSuite.addTest(). This should cause no

8413 -- the failure just occurred later, with a more cumbersome
8414 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008689- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8690 with RFC 3207 and forgets any knowledge obtained from the server not
8691 obtained from the TLS negotiation itself. Patch contributed by Bill
8692 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008693
Georg Brandl3ee81df2008-05-17 18:14:43 +00008694- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008695 that the SMTP.starttls() caller no longer needs to call ehlo()
8696 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008697 does not claim to support starttls. Adds the
8698 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8699 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008753- itertools.chain() now has an alternate constructor,

8779 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8780 silently miscode subclasses of those types. Now, it raises a
8781 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008782

Georg Brandl3ee81df2008-05-17 18:14:43 +00008797 time so that opening a database previously created with the DB_DUP
8798 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8799 opens. Specifically: dictionary assignment to a DB object will
8800 replace all values for a given key when the database allows
8801 duplicate values. DB users should use DB.put(k, v) when they want
8802 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008803

8809 characters with ASCII value less than 32. Also, it correctly quotes
8810 dots only if they occur on a single line, as opposed to the previous
8811 behavior of quoting dots if they are the second character of any
8812 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008813

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009090- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009091 periodic threadstate and signal checking in tight loops. By
9092 default, this option is turned-off. It should only be enabled in
9093 debugged, performance critical applications.

9144-----
9145
Georg Brandl3ee81df2008-05-17 18:14:43 +00009146- Unified naming convention for free lists and their limits. All free
9147 lists in Object/ are named ``free_list``, the counter ``numfree``
9148 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9149 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009150
Georg Brandl3ee81df2008-05-17 18:14:43 +00009151- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9152 to ``PyTuple_SetItem``, it can be used to populate a brand new
9153 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009154

9162
9163- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9164 ``PyFloat_GetInfo()`` to the float API.
9165
Georg Brandl3ee81df2008-05-17 18:14:43 +00009166- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9167 of w# format code incorrectly truncated the length to an int, even
9168 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9169 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009170
Georg Brandl3ee81df2008-05-17 18:14:43 +00009171- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9189- Fix some leftovers from the conversion from int to Py_ssize_t
9190 (relevant to strings and sequences of more than 2**31 items).
9191
9192- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9193 outside of pystate.c and should not be necessary.
9194
Georg Brandl3ee81df2008-05-17 18:14:43 +00009195- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9196 absolute imports. In earlier versions they might have used relative
9197 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009198
Georg Brandl3ee81df2008-05-17 18:14:43 +00009199- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9200 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009201
Georg Brandl3ee81df2008-05-17 18:14:43 +00009202- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

9210 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9211 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9212 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009213

Georg Brandl3ee81df2008-05-17 18:14:43 +00009227- Removed the macfs module. It had been deprecated since Python 2.5.
9228 This lead to the deprecation of macostools.touched() as it relied
9229 solely on macfs and was a no-op under OS X.
