Ned Deily18fae3f2013-01-31 01:24:55 -0800719- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
720 In particular, fix extension module build failures when trying to use
721 32-bit-only installer Pythons on systems with Xcode 4 (currently
722 OS X 10.8, 10.7, and optionally 10.6).
723 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
724 * Since Xcode 4 removes ppc support, extension module builds now
725 check for ppc compiler support and by default remove ppc and
726 ppc64 archs when they are not available.
727 * Extension module builds now revert to using system installed
728 headers and libs (/usr and /System/Library) if the SDK used
729 to build the interpreter is not installed or has moved.
730 * Try to avoid building extension modules with deprecated
731 and problematic Apple llvm-gcc compiler. If original compiler
732 is not available, use clang instead by default.

972 int.__pow__. These overflow checks were causing int.__pow__ to produce
973 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100974 compiler optimizing the check away. Also fix similar overflow checks
975 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001051- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1052 Distutils-based packages with C extension modules may fail because
1053 Apple has removed gcc-4.2, the version used to build python.org
1054 64-bit/32-bit Pythons. If the user does not explicitly override
1055 the default C compiler by setting the CC environment variable,
1056 Distutils will now attempt to compile extension modules with clang
1057 if gcc-4.2 is required but not found. Also as a convenience, if
1058 the user does explicitly set CC, substitute its value as the default
1059 compiler in the Distutils LDSHARED configuration variable for OS X.
1060 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1061 SDK, neither of which are available in Xcode 4. This change does not
1062 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001335- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1336 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1337 interpreter process. This could cause failures in non-Distutils subprocesses
1338 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001339 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001340 deployment target only in the environment of each build subprocess. It is
1341 still possible to globally override the default by setting
1342 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1343 greater or equal to the default value, the value with which the interpreter
1344 was built.

1373 updating the check interval, so if the user decreases the check interval,
1374 the ticker doesn't have to wind down to zero from the old starting point
1375 before the new interval takes effect. And if the user increases the
1376 interval, it makes sure the new limit takes effect right away rather have an
1377 early task switch before recognizing the new interval.

2310
Antoine Pitrou6391b342010-09-14 18:48:19 +00002311- Issue #9854: The default read() implementation in io.RawIOBase now
2312 handles non-blocking readinto() returning None correctly.
2313
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00002314- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
2315 SSLSocket.sendto() to match the corresponding socket methods. Also,
2316 fix various SSLSocket methods to raise socket.error rather than an
2317 unhelpful TypeError when called on an unconnected socket. Original patch
2318 by Andrew Bennetts.

2327
Raymond Hettinger20397532010-09-12 02:11:45 +00002328- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2329 This prevents user-created self-referencing ordered dictionaries from
2330 becoming permanently uncollectable GC garbage. The downside is that
2331 removing __del__ means that the internal doubly-linked list has to wait for
2332 GC collection rather than freeing memory immediately when the refcnt drops
2333 to zero.
2334
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002335- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2338
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002339- Issue #9792: In case of connection failure, socket.create_connection()
2340 would swallow the exception and raise a new one, making it impossible
2341 to fetch the original errno, or to filter timeout errors. Now the
2342 original error is re-raised.
2343
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002344- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2346 be updated back after the system call. Original patch by Brian Brazil.

2353
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002354- Issue #808164: Fixed socket.close to avoid references to globals, to
2355 avoid issues when socket.close is called from a __del__ method.
2356

2358 can be set to False to turn off the previously undocumented 'popularity'
2359 heuristic. Patch by Terry Reedy and Eli Bendersky

2362 falling into recursion.
2363
R. David Murray7c4bf552010-08-25 01:45:57 +00002364- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2365 character years even if the message contains RFC822 two character years.
2366
Daniel Stutzbach91287322010-08-24 21:09:30 +00002367- Issue #8750: Fixed MutableSet's methods to correctly handle

2379 module now correctly return a set. (Patch by Eli Bendersky.)
2380
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002381- Issue #9617: Signals received during a low-level write operation aren't
2382 ignored by the buffered IO layer anymore.
2383
Benjamin Peterson52c36052010-08-21 03:03:22 +00002384- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2385 are not held onto after they are deleted elsewhere.
2386
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002387- Issue #9626: the view methods for collections.OrderedDict() were returning

2394
Antoine Pitroue1436d12010-08-12 15:25:51 +00002395- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2396 and a BadZipfile error is raised if it doesn't match (as used to be the
2397 case in Python 2.5 and earlier).
2398
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002399- Issue #9550: a BufferedReader could issue an additional read when the
2400 original read request had been satisfied, which could block indefinitely
2401 when the underlying raw IO channel was e.g. a socket. Report and original
2402 patch by Jason V. Miller.
2403
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002404- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002422- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2423 This is how it is supposed to work, wget and curl do the same. Previous
2424 behavior was wrong.

2432 the option character for the added 'h/help' option if prefix_chars
2433 does not contain a '-', instead of raising an error.
2434

Georg Brandlfee0f442010-05-22 21:26:21 +00003152- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003153 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3154 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3155 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3175Core and Builtins
3176-----------------
3177
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003178- Issue #7301: Add environment variable $PYTHONWARNINGS.
3179
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003180- Issue #8329: Don't return the same lists from select.select when no fds are
3181 changed.
3182
Georg Brandlfee0f442010-05-22 21:26:21 +00003183- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003184 on 64-bit machines. The shift count for either left or right shift is
3185 permitted to be up to sys.maxsize.
3186
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003187- Ensure that tokenization of identifiers is not affected by locale.
3188
Georg Brandlfee0f442010-05-22 21:26:21 +00003189- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003190
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003191- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3192
Georg Brandlfee0f442010-05-22 21:26:21 +00003193- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3194 with a non-empty format string. This is an effort to future-proof user
3195 code. If a derived class does not currently implement __format__ but later
3196 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003197 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003198 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003199
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003200- Issue #8268: Old-style classes (not just instances) now support weak

3212
Victor Stinner66644262010-03-10 22:30:19 +00003213- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003214 (SIGINT). If an error occurs while importing the site module, the error is
3215 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003216 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003229- Issue #8310: Allow dis to examine new style classes.
3230
Georg Brandlfee0f442010-05-22 21:26:21 +00003231- Issue #8257: The Decimal construct now accepts a float instance directly,
3232 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003233
3234 >>> Decimal(1.1)
3235 Decimal('1.100000000000000088817841970012523233890533447265625')
3236
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003237- collections.Counter() now supports a subtract() method.
3238
Georg Brandlfee0f442010-05-22 21:26:21 +00003239- The functools module now has a total_ordering() class decorator to simplify
3240 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003241
Georg Brandlfee0f442010-05-22 21:26:21 +00003242- The functools module also adds cmp_to_key() as a tool to transition old-style
3243 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003244
Georg Brandlfee0f442010-05-22 21:26:21 +00003245- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3246 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003247
Georg Brandlfee0f442010-05-22 21:26:21 +00003248- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3249 InvalidOperation instead of returning False. (Comparisons involving a quiet
3250 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3251 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003252
Georg Brandlfee0f442010-05-22 21:26:21 +00003253- Issue #2531: Comparison operations between floats and Decimal instances now
3254 return a result based on the numeric values of the operands; previously they
3255 returned an arbitrary result based on the relative ordering of id(float) and
3256 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003257
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003258- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003259 argument `-` which tells it to read files to compile from stdin. Each line is
3260 read on demand and the named file is compiled immediately. (Original patch by
3261 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003262
Georg Brandlfee0f442010-05-22 21:26:21 +00003263- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003266- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3267 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003268 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003269
Georg Brandlfee0f442010-05-22 21:26:21 +00003270- Comparisons using one of <, <=, >, >= between a complex instance and a
3271 Fractions instance now raise TypeError instead of returning True/False. This
3272 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3273 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003274
Michael Foorde6410c52010-03-29 20:04:23 +00003275- Addition of ``WeakSet`` to the ``weakref`` module.

3283
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003284- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003285 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3286 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003287
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003288- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3289 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003329 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3330 log file to compute the next rollover time. If the log file does not exist,
3331 the current time is used as the basis for the computation.

3378 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3379 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003380 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3381 inconsistent: __int__ was used for some integer codes but not for others, and
3382 the set of integer codes for which it was used differed between native packing
3383 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003595- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3596 now also used by regrtest to run all the tests in a temporary directory. The
3597 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3598 Xicluna who helped with the patch.

3615 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003616 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00003635- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3636 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3637 returning NULL. The macro now returns a statically allocated empty string
3638 instead.

3648 strings,
3649 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3650 numeric strings corresponding to subnormal values,
3651 (3) a memory leak for some values large enough to cause overflow, and
3652 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003683- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003684 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003685 Also, raise ValueError rather than TypeError when an unknown TIPC address
3686 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003690- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003691 file position when calling `truncate()`. It would previously change the file
3692 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003693 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3694
Georg Brandlba83f822010-03-14 09:50:54 +00003695- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3696 class used to represent files stored inside an archive. The new
3697 implementation is significantly faster and can be wrapped in a
3698 ``io.BufferedReader`` object for more speedups. It also solves an issue
3699 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3700 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003710- Issue #7748: Since unicode values are supported for some metadata options in
3711 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3712 encoded string for them. This ensures that the upload and register commands
3713 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003790- The ``__complex__()`` method is now looked up on the class of instances to
3791 make it consistent with other special methods.

3795
Mark Dickinson1b34d252010-01-01 17:27:30 +00003796- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003797 DeprecationWarning when passed a float argument where an integer was expected.
3798 These functions and methods now raise TypeError instead. The majority of the
3799 effects of this change are in the extension modules, but some core functions
3800 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3801 and many unicode/str methods.

3815 of integers: the result of a/b is now correctly rounded for ints a and b (at
3816 least on IEEE 754 platforms), and in particular does not depend on the
3817 internal representation of a long.

3825
Georg Brandlba83f822010-03-14 09:50:54 +00003826 These executables now work properly with the arch(1) command: ``arch -ppc
3827 python`` will start a universal binary version of python in PPC mode (unlike
3828 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003984- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3985 decimal string that's guaranteed to round back to x under correct rounding
3986 (with round-half-to-even rounding mode). Previously it gave a string based on
3987 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3988 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3989 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003990
Georg Brandlba83f822010-03-14 09:50:54 +00003991- Issue #7117: On almost all platforms: float-to-string and string-to-float
3992 conversions within Python are now correctly rounded. Places these conversions
3993 occur include: str for floats and complex numbers; the float and complex
3994 constructors; old-style and new-style numeric formatting; serialization and
3995 deserialization of floats and complex numbers using marshal, pickle and json;
3996 parsing of float and imaginary literals in Python code; Decimal-to-float
3997 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003998
Georg Brandlba83f822010-03-14 09:50:54 +00003999 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4000 providing correctly-rounded strtod and dtoa C functions. This code is
4001 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4002 the C compiler. There may be a small number of platforms on which correct
4003 operation of this code cannot be guaranteed, so the code is not used: notably,
4004 this applies to platforms where the C double format is not IEEE 754 binary64,
4005 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4006 and Python's configure script is unable to determine how to change the FPU
4007 precision. On these platforms conversions use the platform strtod and dtoa,
4008 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004009
Georg Brandlba83f822010-03-14 09:50:54 +00004010- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4011 uses the correctly-rounded string <-> float conversions described above (when
4012 available), and so produces correctly rounded results that will display nicely
4013 under the float repr. There are two related small changes: (1) round now
4014 accepts any class with an ``__index__()`` method for its second argument (but
4015 no longer accepts floats for the second argument), and (2) an excessively
4016 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4017 raises an exception.

4166 but with at least one decimal point and with a default precision
4167 of 12. Previously, the behavior the same but with a default precision of 6.
4168 This more closely matches ``str()``, and reduces surprises when adding
4169 alignment flags to the empty presentation type. This also affects the new
4170 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004310- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4311 existing .py counterpart, override the co_filename attributes of all code

4367
Georg Brandlba83f822010-03-14 09:50:54 +00004368- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4369 file objects with closefd=False. The file descriptor is still kept open but
4370 the file object behaves like a closed file. The ``FileIO`` object also got a
4371 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004391- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004394- On windows, ``os.chdir()`` given unicode was not working if

4396 this code path is really executed because I cannot move to such directory on
4397 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004399- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4400 element is temporarily replaced with an equivalent frozenset. But the
4401 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00004422- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4423 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4424 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4425 of using the replace error handler in PyUnicode_DecodeUTF8().
4426
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004427- Issue #3739: The unicode-internal encoder now reports the number of characters

4429
Georg Brandlba83f822010-03-14 09:50:54 +00004430- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4432 gives improved memory leak detection when running under Valgrind, while taking
4433 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005656 leak-chasing test runs give sensible results. The previous method of reaping
5657 threads could return successfully while some Thread objects were still
5658 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005675- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5676 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005677 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5678 the tests if DISPLAY is defined but can't be used.

5681 regression tests in parallel, shortening the total runtime.
5682
Georg Brandlba83f822010-03-14 09:50:54 +00005683- Issue #5354: New test support function import_fresh_module() makes it easy to
5684 import both normal and optimised versions of modules. test_heapq and
5685 test_warnings have been adjusted to use it, tests for other modules with both
5686 C and Python implementations in the stdlib can be adjusted to use it over
5687 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005695- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5696 should cause a test to be skipped are now done using import_module from test
5697 support, which does the conversion.

5799
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005800- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5801 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5802 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5803 ``printf`` function, whereas PyString_FromFormat has an independent
5804 implementation and uses "%zd" on all platforms for size_t values.
5805 This makes a difference on win64, where ``printf`` needs "%Id" to display
5806 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005808- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5812 object; previously an int would be returned for small values. the __long__
5813 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005823 was correctly parsed but parsing of subsequent arguments failed.
5824
Vinay Sajip35e3b032008-09-01 14:33:59 +00005825- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005826 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5827 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5828 when given a tuple of classes as second argument, were looking up
5829 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5830 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005969What's New in Python 2.6 beta 3?
5970================================
5971
Barry Warsaw07a4a382008-08-21 01:15:08 +00005972*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005973
5974Core and Builtins
5975-----------------
5976
Guido van Rossumf8402962008-08-20 15:01:50 +00005977- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5978 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5979 extensions do not automatically benefit from the class attribute
5980 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5981 to their tp_flags field if they care. This is a backwards
5982 compatibility feature; in 3.0, all types will use the cache by
5983 default.
5984
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005985- Keyword arguments can now follow starred arguments. (``f(a, *args,
5986 keyword=23)`` is now valid syntax.)
5987
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005988- ctypes function pointers that are COM methods have a boolean True
5989 value again.
5990
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005991- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5992 by denying s# to parse objects that have a releasebuffer procedure,
5993 and introducing s*.
5994
Georg Brandl1e13ea92008-08-11 09:07:59 +00005995- Issue #3537: Fix an assertion failure when an empty but presized dict
5996 object was stored in the freelist.
5997
Mark Dickinsonb6467572008-08-04 21:30:09 +00005998- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5999 ValueError consistently across platforms.
6000
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006001- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6002 (64bit Unix, for example), unichr() would truncate its argument and return
6003 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6004
Neal Norwitze7d8be82008-07-31 17:17:14 +00006005- Apply security patches from Apple.
6006
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006007- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6008 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6009
Antoine Pitrou92f82162008-07-25 22:22:08 +00006010- Issue #1819: function calls with several named parameters are now on
6011 average 35% faster (as measured by pybench).
6012
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006013- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6014 the python debugger steps into a class statement: the free variables (local
6015 variables defined in an outer scope) would be deleted from the outer scope.
6016
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006017- Issue #2620: Overflow checking when allocating or reallocating memory
6018 was not always being done properly in some python types and extension
6019 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6020 all been updated to perform better checks and places in the code that
6021 would previously leak memory on the error path when such an allocation
6022 failed have been fixed.

6025-------
6026
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006027- Issue #3612: Added some missing basic types in ctypes.wintypes.
6028
Benjamin Petersone977ad42008-08-20 01:42:01 +00006029- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6030 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6031
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006032- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6033 version reported by these tools does not necessarily follow the python
6034 version numbering scheme, so the module is less strict when parsing it.
6035
Nick Coghlanf70385a2008-08-18 12:42:46 +00006036- Issue #2235: Added Py3k warnings for types which will become unhashable
6037 under the stricter __hash__ inheritance rules in 3.0. Several types
6038 which did not meet the rules for hash invariants and were already
6039 unhashable in 3.0 have now been explicitly flagged as unhashable in
6040 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6041 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6042
Brett Cannon88f801d2008-08-18 00:46:22 +00006043- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6044 imported into the module but exposed as part of the module's API.
6045
Brett Cannon7b96f072008-08-18 00:41:11 +00006046- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6047
Brett Cannon46225e72008-08-18 00:36:52 +00006048- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6049
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006050- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6051
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006052- Issue #3575: Incremental decoder's decode function now takes bytearray
6053 by using 's*' instead of 't#'.
6054
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006055- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006056 fails unicode conversion on 2nd parameter. (windows only)
6057
Georg Brandl222e2082010-08-01 22:27:39 +00006058- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006059 in a redirect.
6060
Brett Cannonabe423e2008-08-16 21:47:07 +00006061- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006062 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006063
Facundo Batistaeb90b782008-08-16 14:44:07 +00006064- Issue #2776: fixed small issue when handling an URL with double slash
6065 after a 302 response in the case of not going through a proxy.
6066
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006067- Issue #2676: in the email package, content-type parsing was hanging on
6068 pathological input because of quadratic or exponential behaviour of a
6069 regular expression.
6070
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006071- Issue #3476: binary buffered reading through the new "io" library is now
6072 thread-safe.
6073
Brett Cannonbf3157b2008-08-14 05:00:03 +00006074- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6075 since mimetools itself is deprecated. Because modules are cached, all
6076 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6077
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006078- Issue #3134: shutil referenced undefined WindowsError symbol.
6079
Robert Schuppenies14646332008-08-10 11:01:53 +00006080- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6081 menu entries were not deleted.
6082
Brett Cannon83e81842008-08-09 23:30:55 +00006083- Copied the implementation of reduce() to _functools.reduce() to have a
6084 version that did not raise a DeprecationWarning under -3.
6085
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006086- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6087 a MemoryError rather than silently stop the iteration.
6088
Guido van Rossum59ce9012008-08-09 14:55:34 +00006089- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6090 to _sre.compile() will now be rejected. This should not affect anybody
6091 since the re.compile() function never generates invalid re-bytecode.
6092
Skip Montanaroa032bf42008-08-08 22:52:51 +00006093- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6094 upon first access it can be automatically initialized from the csv file if
6095 it wasn't initialized during instantiation.
6096
Brett Cannon3aa2a492008-08-06 22:28:09 +00006097- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6098 the reload() built-in has been removed.
6099
Brett Cannon7e30b672008-08-04 21:52:25 +00006100- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006101 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6109 raised an AttributeError.
6110
Benjamin Peterson01a24322008-07-28 23:35:27 +00006111- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006112 asking for a specific length. This problem only affected files opened
6113 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006114
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006115- Issue #3449: Update decimal module to use most recent specification
6116 (v. 1.68) and tests (v. 2.58) from IBM.
6117
Georg Brandl222e2082010-08-01 22:27:39 +00006118- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6122
Georg Brandlf9efabb2008-07-23 15:16:45 +00006123- Deprecate the "ast" parser function aliases.
6124
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006125- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6126
6127- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6128 invalid arguments.
6129
6130- Issue #3302: Fix several crashes when calling locale's gettext functions
6131 with None arguments.
6132
6133- Issue #3389: Allow resolving dotted names for handlers in logging
6134 configuration files.
6135

6137
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006138- Issue #3394: zipfile.writestr sets external attributes when passed a
6139 file name rather than a ZipInfo instance, so files are extracted with
6140 mode 0600 rather than 000 under Unix.
6141
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006142- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6143 argument in python 2.5, this broke code that subclassed Popen to include its
6144 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6153
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006154- Issue #2235: the C API function PyObject_HashNotImplemented and its
6155 interaction with the tp_hash slot (added in 2.6b2) are now documented
6156
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006157- Issue #643841: The language reference now provides more detailed
6158 coverage of the lookup process for special methods. The disclaimers
6159 regarding lack of coverage of new-style classes have also been
6160 removed, since the coverage is now fairly reasonable.

6165
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006166*Release date: 17-Jul-2008*

6169-----------------
6170
Georg Brandl3e483f62008-07-16 22:57:41 +00006171- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6172 its methods now allow for items objects that can be converted to
6173 an integer using operator.index().
6174
Mark Dickinson64b7e502008-07-16 09:40:03 +00006175- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6176 produced a ValueError instead of giving the correct float.
6177
Eric Smitha5fa5a22008-07-16 00:11:49 +00006178- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6179 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6180
Mark Dickinson7103aa42008-07-15 19:08:33 +00006181- Issue #3008: the float type has a new instance method 'float.hex'
6182 and a new class method 'float.fromhex' to convert floating-point
6183 numbers to and from hexadecimal strings, respectively.
6184
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006185- Issue #2235: __hash__ is once again inherited by default. To allow
6186 collections.Hashable to remain meaningful in the presence of the
6187 default hash implementation (object.__hash__), it is now possible
6188 to explicit block inheritance of hash by setting __hash__=None at
6189 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6190 level.
6191
Nick Coghlanb028f502008-07-13 14:52:36 +00006192- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6193 the parent module cannot be found while performing an absolute import.
6194 This means that an incorrectly defined __package__ attribute will
6195 now only prevent relative imports in that module rather than causing
6196 all imports from that module to fail.
6197
Nick Coghlan14ff9942008-07-08 14:21:42 +00006198- Issue #2517: Allow unicode messages in Exceptions again by correctly
6199 bypassing the instance dictionary when looking up __unicode__ on
6200 new-style classes.
6201
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006202- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6203 set to a custom object whose write() method happens to install
6204 another file in sys.stdout.
6205
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006206- Issue #3088: Corrected a race condition in classes derived from
6207 threading.local: the first member set by a thread could be saved in
6208 another thread's dictionary.
6209
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006210- Issue #3004: Minor change to slice.indices(): the start and stop
6211 arguments are now treated identically, making the behaviour easier
6212 to describe and understand. For example, slice(None, -10,
6213 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6214 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6215 10, -1).
6216
Georg Brandl278fc502008-07-19 12:46:12 +00006217- Issue #3219: Calling a function with repeated keyword arguments,
6218 f(a=2, a=23), would not cause a syntax error. This was a regression
6219 from 2.4 caused by the switch to the new compiler.

6222 other freelists. Changes their CompactFreeList apis into
6223 ClearFreeList apis and calls them via gc.collect().

6229 api functions without holding the GIL, which could lead to a fatal
6230 error when they failed.
6231

Georg Brandl5cc774e2008-06-11 20:28:06 +00006669 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006670
6671 This is controlled by the configure argument ``--with-universal-archs``:
6672
6673 - ``--with-universal-archs=all``: install 4-way universal
6674
6675 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6676
6677 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6678
6679 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006731- Issue #1631171: Re-implement the 'warnings' module in C (the
6732 original Python code has been kept as backup). This will allow for
6733 using the 'warning's machinery in such places as the parser where
6734 use of pure Python code is not possible. Both the ``showarning()``
6735 and ``formatwarning()`` gain an optional 'line' argument which is
6736 not called by default for backwards-compatibility reasons. Setting
6737 ``warnings.showwarning()`` to an implementation that lacks support
6738 for the ``line`` argument will raise a DeprecationWarning.

6762
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006763- The getpass module has been improved on Unix. It now uses /dev/tty
6764 by default and uses stderr instead of stdout. A GetPassWarning is
6765 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006801- Issue #2550: The approach used by client/server code for obtaining
6802 ports to listen on in network-oriented tests has been refined in an
6803 effort to facilitate running multiple instances of the entire
6804 regression test suite in parallel without issue.
6805 test_support.bind_port() has been fixed such that it will always
6806 return a unique port -- which wasn't always the case with the
6807 previous implementation, especially if socket options had been set
6808 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6809 new implementation of bind_port() will actually raise an exception
6810 if it is passed an AF_INET/SOCK_STREAM socket with either the
6811 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6812 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6813 the socket it's been passed. This currently only applies to
6814 Windows. This option prevents any other sockets from binding to the
6815 host/port we've bound to, thus removing the possibility of the
6816 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6817 when a second SOCK_STREAM socket binds and accepts to a host/port
6818 that's already been bound by another socket. The optional preferred
6819 port parameter to bind_port() has been removed. Under no
6820 circumstances should tests be hard coding ports!
6821
6822 test_support.find_unused_port() has also been introduced, which will
6823 pass a temporary socket object to bind_port() in order to obtain an
6824 unused port. The temporary socket object is then closed and
6825 deleted, and the port is returned. This method should only be used
6826 for obtaining an unused port in order to pass to an external program
6827 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6828 a parameter to a server-oriented class that doesn't give you direct
6829 access to the underlying socket used.
6830
6831 Finally, test_support.HOST has been introduced, which should be used
6832 for the host argument of any relevant socket calls (i.e. bind and
6833 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006834
6835 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006837 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6838 test_asynchat and test_socket_ssl.
6839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840 It is now possible for multiple instances of the regression test
6841 suite to run in parallel without issue.

7046 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007047 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
7048 files are used. On all linux systems the --with-system-ffi
7049 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00007110- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007111 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00007120- Added the future_builtins module, which contains hex() and oct().
7121 These are the PEP 3127 version of these functions, designed to be
7122 compatible with the hex() and oct() builtins from Python 3.0. They
7123 differ slightly in their output formats from the existing, unchanged
7124 Python 2.6 builtins. The expected usage of the future_builtins
7125 module is:
7126 from future_builtins import hex, oct
7127
Eric Smith7ef40bf2008-02-20 23:34:22 +00007128- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7129 exponents for exponents with absolute value < 100. Follows C99
7130 standard. This is a change on Windows, which would use 3 digits.
7131 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7132 so that any alterations it does to the resulting string will be
7133 available in stringlib/formatter.h (for float.__format__).
7134
Eric Smith5a3c1352008-02-19 13:21:56 +00007135- Implemented PEP 3101, Advanced String Formatting. This adds a new
7136 builtin format(); a format() method for str and unicode; a
7137 __format__() method to object, str, unicode, int, long, float, and
7138 datetime; the class string.Formatter; and the C API
7139 PyObject_Format().
7140
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141- Fixed several potential crashes, all caused by specially crafted
7142 __del__ methods exploiting objects in temporarily inconsistent
7143 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007144
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007145- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146 prevent a possible crash: an Abstract Base Class would try to access
7147 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007148

Georg Brandl3ee81df2008-05-17 18:14:43 +00007152- Clear all free lists during a gc.collect() of the highest generation
7153 in order to allow pymalloc to free more arenas. Python may give back
7154 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007155
Georg Brandl3ee81df2008-05-17 18:14:43 +00007156- Issue #2045: Fix an infinite recursion triggered when printing a
7157 subclass of collections.defaultdict, if its default_factory is set
7158 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007159
Christian Heimesf75dbef2008-02-08 00:11:31 +00007160- Fixed a minor memory leak in dictobject.c. The content of the free
7161 list was not freed on interpreter shutdown.
7162
Georg Brandl21e99f42010-03-07 15:23:59 +00007163- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007165
Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7167 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007168 to compact the internal free lists of pre-allocted ints and floats.
7169
Georg Brandl3ee81df2008-05-17 18:14:43 +00007170- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7171 calls. Python expected the return type int but the fork familie
7172 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007173
Georg Brandl3ee81df2008-05-17 18:14:43 +00007174- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7175 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007186- Patch #1473257: generator objects gain a gi_code attribute. This is
7187 the same object as the func_code attribute of the function that
7188 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007189
Georg Brandl3ee81df2008-05-17 18:14:43 +00007190- Issue #1920: "while 0" statements were completely removed by the
7191 compiler, even in the presence of an "else" clause, which is
7192 supposed to be run when the condition is false. Now the compiler
7193 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007194
Guido van Rossumeead05f2008-01-24 18:21:02 +00007195- A few crashers fixed: weakref_in_del.py (issue #1377858);
7196 loosing_dict_ref.py (issue #1303614, test67.py);
7197 borrowed_ref_[34].py (not in tracker).
7198
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007199- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007200 suppressed while an extension is loaded by calling SetErrorMode in
7201 dynload_win.c. The error is still reported properly.
7202
Georg Brandl3ee81df2008-05-17 18:14:43 +00007203- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007204 several extension methods and modules do not work without unicode
7205 support.
7206
Georg Brandl26543b12008-01-21 18:36:51 +00007207- Issue #1882: when compiling code from a string, encoding cookies in the
7208 second line of code were not always recognized correctly.
7209
Georg Brandl14404b62008-01-19 19:27:05 +00007210- Issue #1679: "0x" was taken as a valid integer literal.
7211
Georg Brandl6caad7d2008-01-26 14:19:22 +00007212- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007213 added.
7214
Christian Heimesc94e2b52008-01-14 04:13:37 +00007215- sys.float_info / PyFloat_GetInfo: The floating point information
7216 object was converted from a dict to a specialized structseq object.
7217
Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Patch #1816: Added sys.flags structseq. It exposes the status of
7219 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007220
Georg Brandl3ee81df2008-05-17 18:14:43 +00007221- Objects/structseq.c: Implemented new structseq representation. The
7222 patch makes structseqs (e.g. the return value of os.stat) more
7223 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007224
Georg Brandl3ee81df2008-05-17 18:14:43 +00007225- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007237- Improve some exception messages when Windows fails to load an
7238 extension module. Now we get for example '%1 is not a valid Win32
7239 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007247 and INF. float("nan"), float("inf") and float("-inf") now work on
7248 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007249
Georg Brandl3ee81df2008-05-17 18:14:43 +00007250- Compiler now generates simpler and faster code for dictionary
7251 literals. The oparg for BUILD_MAP now indicates an estimated
7252 dictionary size. There is a new opcode, STORE_MAP, for adding
7253 entries to the dictionary.

7296
Georg Brandl21e99f42010-03-07 15:23:59 +00007297- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007298 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7299 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007300
Georg Brandl3ee81df2008-05-17 18:14:43 +00007301- Issue #1686386: Tuple's tp_repr did not take into account the
7302 possibility of having a self-referential tuple, which is possible
7303 from C code. Nor did object's tp_str consider that a type's tp_str
7304 could do something that could lead to an inifinite recursion.
7305 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7306 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007307
Georg Brandl3ee81df2008-05-17 18:14:43 +00007308- Issue #1164: It was possible to trigger deadlock when using the
7309 'print' statement to write to a file since the GIL was not released
7310 as needed. Now PyObject_Print() does the right thing along with
7311 various tp_print implementations of the built-in types and those in
7312 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007313
Georg Brandl3ee81df2008-05-17 18:14:43 +00007314- Issue #1147: Exceptions were directly allowing string exceptions in

7316 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007320
Brett Cannon1e534b52007-09-07 04:18:30 +00007321- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007322 PyObject_Call() never calling back out to Python code to trigger
7323 recursion depth updates/checks. Required the creation of a static
7324 RuntimeError instance in case normalizing an exception put the
7325 recursion check value past its limit. Fixes crashers
7326 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007341- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342 __*__ attributes. (Some already existed, e.g., __doc__ and
7343 __name__.)

7347
Georg Brandl2134e752007-05-21 20:34:16 +00007348- Patch #1686487: you can now pass any mapping after '**' in function
7349 calls.
7350
Collin Winter62903052007-05-18 23:11:24 +00007351- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007352 "except E as target:". This is to provide forwards compatibility
7353 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007360- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007361 setting a plain string, ie don't expand to single letter identifiers.
7362
Raymond Hettinger13936692007-04-11 18:40:58 +00007363- Request #1191699: Slices can now be pickled.
7364
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007365- Request #1193128: str.translate() now allows a None argument for

7367 remaining characters.
7368
Georg Brandl5cb76c12007-03-21 09:00:39 +00007369- Patch #1682205: a TypeError while unpacking an iterable is no longer

7373
Guido van Rossum143b5642007-03-23 04:58:42 +00007374- Bug #1683368: The object.__init__() and object.__new__() methods are
7375 now stricter in rejecting excess arguments. The only time when
7376 either allows excess arguments is when it is not overridden and the
7377 other one is. For backwards compatibility, when both are
7378 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007379 warning later). Also, type.__init__() insists on the same signature
7380 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007381
Georg Brandl3ee81df2008-05-17 18:14:43 +00007382- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7383 object to complex using its __complex__() method before falling back
7384 to the __float__() method. Therefore, the functions in the cmath
7385 module now can operate on objects that define a __complex__()
7386 method.

7397 its type.

7403
Georg Brandl7b9c5552007-03-12 14:30:05 +00007404- Bug #1678647: write a newline after printing an exception in any
7405 case, even when converting the value to a string failed.
7406
Georg Brandl871f1bc2007-03-12 13:17:36 +00007407- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408 its argument, if it exists. If not, it will work like before. This
7409 allows customizing the output of dir() in the presence of a
7410 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007418- Patch #1491866: change the complex() constructor to allow
7419 parthensized forms. This means complex(repr(x)) now works instead of
7420 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007421
Georg Brandlaa2321b2007-03-07 00:40:28 +00007422- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007423 makes the filenames the warning module prints much more sensible
7424 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007425

Georg Brandl0fca97a2007-03-05 22:28:08 +00007437- Patch #1674228: when assigning a slice (old-style), check for the
7438 sq_ass_slice instead of the sq_slice slot.
7439
Georg Brandl3ee81df2008-05-17 18:14:43 +00007440- When printing an unraisable error, don't print exceptions. before
7441 the name. This duplicates the behavior whening normally printing
7442 exceptions.

8071 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8353 with RFC 3207 and forgets any knowledge obtained from the server not
8354 obtained from the TLS negotiation itself. Patch contributed by Bill
8355 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008356
Georg Brandl3ee81df2008-05-17 18:14:43 +00008357- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008358 that the SMTP.starttls() caller no longer needs to call ehlo()
8359 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008360 does not claim to support starttls. Adds the
8361 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8442 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8443 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00008445

Georg Brandl3ee81df2008-05-17 18:14:43 +00008460 time so that opening a database previously created with the DB_DUP
8461 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8462 opens. Specifically: dictionary assignment to a DB object will
8463 replace all values for a given key when the database allows
8464 duplicate values. DB users should use DB.put(k, v) when they want
8465 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008466

8472 characters with ASCII value less than 32. Also, it correctly quotes
8473 dots only if they occur on a single line, as opposed to the previous
8474 behavior of quoting dots if they are the second character of any
8475 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008476

Georg Brandl3ee81df2008-05-17 18:14:43 +00008800- Unified naming convention for free lists and their limits. All free
8801 lists in Object/ are named ``free_list``, the counter ``numfree``

8803 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008804
Georg Brandl3ee81df2008-05-17 18:14:43 +00008805- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8806 to ``PyTuple_SetItem``, it can be used to populate a brand new

8819
Georg Brandl3ee81df2008-05-17 18:14:43 +00008820- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8821 of w# format code incorrectly truncated the length to an int, even
8822 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8823 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008824
Georg Brandl3ee81df2008-05-17 18:14:43 +00008825- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8843- Fix some leftovers from the conversion from int to Py_ssize_t
8844 (relevant to strings and sequences of more than 2**31 items).
8845
8846- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8847 outside of pystate.c and should not be necessary.
8848
Georg Brandl3ee81df2008-05-17 18:14:43 +00008849- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8850 absolute imports. In earlier versions they might have used relative
8851 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008852
Georg Brandl3ee81df2008-05-17 18:14:43 +00008853- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8854 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008855
Georg Brandl3ee81df2008-05-17 18:14:43 +00008856- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8864 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8865 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8866 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008867

Georg Brandl3ee81df2008-05-17 18:14:43 +00008881- Removed the macfs module. It had been deprecated since Python 2.5.
8882 This lead to the deprecation of macostools.touched() as it relied
8883 solely on macfs and was a no-op under OS X.
