Ned Deily18fae3f2013-01-31 01:24:55 -0800894- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
895 In particular, fix extension module build failures when trying to use
896 32-bit-only installer Pythons on systems with Xcode 4 (currently
897 OS X 10.8, 10.7, and optionally 10.6).
898 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
899 * Since Xcode 4 removes ppc support, extension module builds now
900 check for ppc compiler support and by default remove ppc and
901 ppc64 archs when they are not available.
902 * Extension module builds now revert to using system installed
903 headers and libs (/usr and /System/Library) if the SDK used
904 to build the interpreter is not installed or has moved.
905 * Try to avoid building extension modules with deprecated
906 and problematic Apple llvm-gcc compiler. If original compiler
907 is not available, use clang instead by default.

1257
Mark Dickinsondbbed042011-09-19 16:38:08 +01001258- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1259 int.__pow__. These overflow checks were causing int.__pow__ to produce
1260 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001261 compiler optimizing the check away. Also fix similar overflow checks
1262 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1263 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001274- Issue #12149: Update the method cache after a type's dictionnary gets
1275 cleared by the garbage collector. This fixes a segfault when an instance
1276 and its type get caught in a reference cycle, and the instance's
1277 deallocator calls one of the methods on the type (e.g. when subclassing
1278 IOBase). Diagnosis and patch by Davide Rizzo.
1279
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01001280- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02001287 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1288 raw_input() interrupted by CTRL+c.
1289
Łukasz Langa7a153902011-10-18 17:16:00 +02001290- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01001331- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001332 has left two versions of customize_compiler, the original in
1333 distutils.sysconfig and another copy in distutils.ccompiler, with some
1334 parts of distutils calling one and others using the other.

1336 is the case in 3.x.
1337
Ned Deily0d0ea482012-02-10 12:59:06 +01001338- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1339 Distutils-based packages with C extension modules may fail because
1340 Apple has removed gcc-4.2, the version used to build python.org
1341 64-bit/32-bit Pythons. If the user does not explicitly override
1342 the default C compiler by setting the CC environment variable,
1343 Distutils will now attempt to compile extension modules with clang
1344 if gcc-4.2 is required but not found. Also as a convenience, if
1345 the user does explicitly set CC, substitute its value as the default
1346 compiler in the Distutils LDSHARED configuration variable for OS X.
1347 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1348 SDK, neither of which are available in Xcode 4. This change does not
1349 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001599- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1600 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1601 interpreter process. This could cause failures in non-Distutils subprocesses
1602 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001603 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001604 deployment target only in the environment of each build subprocess. It is
1605 still possible to globally override the default by setting
1606 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1607 greater or equal to the default value, the value with which the interpreter
1608 was built.

1638 the ticker doesn't have to wind down to zero from the old starting point
1639 before the new interval takes effect. And if the user increases the
1640 interval, it makes sure the new limit takes effect right away rather have an
1641 early task switch before recognizing the new interval.

2622 This prevents user-created self-referencing ordered dictionaries from
2623 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003085- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3086 start byte and the continuation byte(s) are now considered invalid, instead
3087 of the number of bytes specified by the start byte.
3088 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3089 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3090 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3100 objects. (1) The comparison could incorrectly return True in some cases
3101 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3102 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00003214- On darwin, ``test_site`` assumed that a framework build was being used,
3215 leading to a failure where four directories were expected for site-packages
3216 instead of two in a non-framework build.

Georg Brandlfee0f442010-05-22 21:26:21 +00003243- Issue #1533: Fix inconsistency in range function argument processing: any
3244 non-float non-integer argument is now converted to an integer (if possible)
3245 using its __int__ method. Previously, only small arguments were treated this
3246 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00003297- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3298 operation raises multiple signals and more than one of those signals is
3299 trapped, the specification determines the order in which the signals should be
3300 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00003445- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003446 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3447 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3448 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3468Core and Builtins
3469-----------------
3470
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003471- Issue #7301: Add environment variable $PYTHONWARNINGS.
3472
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003473- Issue #8329: Don't return the same lists from select.select when no fds are
3474 changed.
3475
Georg Brandlfee0f442010-05-22 21:26:21 +00003476- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003477 on 64-bit machines. The shift count for either left or right shift is
3478 permitted to be up to sys.maxsize.
3479
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003480- Ensure that tokenization of identifiers is not affected by locale.
3481
Georg Brandlfee0f442010-05-22 21:26:21 +00003482- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003483
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003484- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3485
Georg Brandlfee0f442010-05-22 21:26:21 +00003486- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3487 with a non-empty format string. This is an effort to future-proof user
3488 code. If a derived class does not currently implement __format__ but later
3489 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003490 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003491 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003492
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003493- Issue #8268: Old-style classes (not just instances) now support weak
3494 references.
3495

3497 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003498

3502 arguments to a function correct.
3503
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003504- Issue #8164: Don't allow lambda functions to have a docstring.
3505
Victor Stinner66644262010-03-10 22:30:19 +00003506- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003507 (SIGINT). If an error occurs while importing the site module, the error is
3508 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003509 module.

3517
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003518- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003519 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3520 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003522- Issue #8310: Allow dis to examine new style classes.
3523
Georg Brandlfee0f442010-05-22 21:26:21 +00003524- Issue #8257: The Decimal construct now accepts a float instance directly,
3525 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003526
3527 >>> Decimal(1.1)
3528 Decimal('1.100000000000000088817841970012523233890533447265625')
3529
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003530- collections.Counter() now supports a subtract() method.
3531
Georg Brandlfee0f442010-05-22 21:26:21 +00003532- The functools module now has a total_ordering() class decorator to simplify
3533 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003534
Georg Brandlfee0f442010-05-22 21:26:21 +00003535- The functools module also adds cmp_to_key() as a tool to transition old-style
3536 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003537
Georg Brandlfee0f442010-05-22 21:26:21 +00003538- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3539 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003540
Georg Brandlfee0f442010-05-22 21:26:21 +00003541- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3542 InvalidOperation instead of returning False. (Comparisons involving a quiet
3543 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3544 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003545
Georg Brandlfee0f442010-05-22 21:26:21 +00003546- Issue #2531: Comparison operations between floats and Decimal instances now
3547 return a result based on the numeric values of the operands; previously they
3548 returned an arbitrary result based on the relative ordering of id(float) and
3549 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003550
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003551- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003552 argument `-` which tells it to read files to compile from stdin. Each line is
3553 read on demand and the named file is compiled immediately. (Original patch by
3554 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003555
Georg Brandlfee0f442010-05-22 21:26:21 +00003556- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3557 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003559- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3560 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003561 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003562
Georg Brandlfee0f442010-05-22 21:26:21 +00003563- Comparisons using one of <, <=, >, >= between a complex instance and a
3564 Fractions instance now raise TypeError instead of returning True/False. This
3565 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3566 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003567
Michael Foorde6410c52010-03-29 20:04:23 +00003568- Addition of ``WeakSet`` to the ``weakref`` module.

3576
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003577- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003578 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3579 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003580
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003581- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3582 deprecated.
3583
Georg Brandlfee0f442010-05-22 21:26:21 +00003584- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3585 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003586

3591 existing at the same time, causing a Unicode error when configuration code
3592 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003593
Georg Brandlfee0f442010-05-22 21:26:21 +00003594- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
3595 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00003597- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3598 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3599 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003621- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003622 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3623 log file to compute the next rollover time. If the log file does not exist,
3624 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003625

Georg Brandlba83f822010-03-14 09:50:54 +00003634- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3635 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3636 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003665- Issue #8300: When passing a non-integer argument to struct.pack with any
3666 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003670- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3671 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3672 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003673 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3674 inconsistent: __int__ was used for some integer codes but not for others, and
3675 the set of integer codes for which it was used differed between native packing
3676 and standard packing.)

4261 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004262
Georg Brandlba83f822010-03-14 09:50:54 +00004263- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4264 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004265
Georg Brandlba83f822010-03-14 09:50:54 +00004266- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4267 1e-100 used to raise OverflowError, but now gives the requested 120
4268 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004276
Georg Brandlba83f822010-03-14 09:50:54 +00004277- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4278 decimal string that's guaranteed to round back to x under correct rounding
4279 (with round-half-to-even rounding mode). Previously it gave a string based on
4280 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4281 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4282 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004283
Georg Brandlba83f822010-03-14 09:50:54 +00004284- Issue #7117: On almost all platforms: float-to-string and string-to-float
4285 conversions within Python are now correctly rounded. Places these conversions
4286 occur include: str for floats and complex numbers; the float and complex
4287 constructors; old-style and new-style numeric formatting; serialization and
4288 deserialization of floats and complex numbers using marshal, pickle and json;
4289 parsing of float and imaginary literals in Python code; Decimal-to-float
4290 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004291
Georg Brandlba83f822010-03-14 09:50:54 +00004292 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4293 providing correctly-rounded strtod and dtoa C functions. This code is
4294 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4295 the C compiler. There may be a small number of platforms on which correct
4296 operation of this code cannot be guaranteed, so the code is not used: notably,
4297 this applies to platforms where the C double format is not IEEE 754 binary64,
4298 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4299 and Python's configure script is unable to determine how to change the FPU
4300 precision. On these platforms conversions use the platform strtod and dtoa,
4301 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004302
Georg Brandlba83f822010-03-14 09:50:54 +00004303- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4304 uses the correctly-rounded string <-> float conversions described above (when
4305 available), and so produces correctly rounded results that will display nicely
4306 under the float repr. There are two related small changes: (1) round now
4307 accepts any class with an ``__index__()`` method for its second argument (but
4308 no longer accepts floats for the second argument), and (2) an excessively
4309 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4310 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004314- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00004453 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4454 (2) parsing of strings representing infinities and nans was locale aware; and
4455 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004457- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4458 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4459 but with at least one decimal point and with a default precision
4460 of 12. Previously, the behavior the same but with a default precision of 6.
4461 This more closely matches ``str()``, and reduces surprises when adding
4462 alignment flags to the empty presentation type. This also affects the new
4463 complex.__format__ in the same way.

4660
Georg Brandlba83f822010-03-14 09:50:54 +00004661- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4662 file objects with closefd=False. The file descriptor is still kept open but
4663 the file object behaves like a closed file. The ``FileIO`` object also got a
4664 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004684- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004687- On windows, ``os.chdir()`` given unicode was not working if
4688 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4689 this code path is really executed because I cannot move to such directory on
4690 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004692- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4693 element is temporarily replaced with an equivalent frozenset. But the
4694 eventual KeyError would always report the empty ``frozenset()`` as the missing
4695 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004715- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4716 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4717 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4718 of using the replace error handler in PyUnicode_DecodeUTF8().
4719
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004720- Issue #3739: The unicode-internal encoder now reports the number of characters

4722
Georg Brandlba83f822010-03-14 09:50:54 +00004723- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4724 allocator will be automatically disabled when running under Valgrind. This
4725 gives improved memory leak detection when running under Valgrind, while taking
4726 advantage of pymalloc at other times.

5972 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005973 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5974 the tests if DISPLAY is defined but can't be used.

5980 import both normal and optimised versions of modules. test_heapq and
5981 test_warnings have been adjusted to use it, tests for other modules with both
5982 C and Python implementations in the stdlib can be adjusted to use it over
5983 time.

5993 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006094- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6095
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006096- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6097 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6098 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6099 ``printf`` function, whereas PyString_FromFormat has an independent
6100 implementation and uses "%zd" on all platforms for size_t values.
6101 This makes a difference on win64, where ``printf`` needs "%Id" to display
6102 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006104- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6108 object; previously an int would be returned for small values. the __long__
6109 method is allowed to return either an int or a long, but the behaviour of
6110 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006112- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006118 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006119 was correctly parsed but parsing of subsequent arguments failed.
6120
Vinay Sajip35e3b032008-09-01 14:33:59 +00006121- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006122 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6123 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6124 when given a tuple of classes as second argument, were looking up
6125 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6126 type object.
6127
Neal Norwitz18aa3882008-08-24 05:04:52 +00006128- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006265What's New in Python 2.6 beta 3?
6266================================
6267
Barry Warsaw07a4a382008-08-21 01:15:08 +00006268*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006269
6270Core and Builtins
6271-----------------
6272
Guido van Rossumf8402962008-08-20 15:01:50 +00006273- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6274 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6275 extensions do not automatically benefit from the class attribute
6276 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6277 to their tp_flags field if they care. This is a backwards
6278 compatibility feature; in 3.0, all types will use the cache by
6279 default.
6280
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006281- Keyword arguments can now follow starred arguments. (``f(a, *args,
6282 keyword=23)`` is now valid syntax.)
6283
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006284- ctypes function pointers that are COM methods have a boolean True
6285 value again.
6286
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006287- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6288 by denying s# to parse objects that have a releasebuffer procedure,
6289 and introducing s*.
6290
Georg Brandl1e13ea92008-08-11 09:07:59 +00006291- Issue #3537: Fix an assertion failure when an empty but presized dict
6292 object was stored in the freelist.
6293
Mark Dickinsonb6467572008-08-04 21:30:09 +00006294- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6295 ValueError consistently across platforms.
6296
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006297- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6298 (64bit Unix, for example), unichr() would truncate its argument and return
6299 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6300
Neal Norwitze7d8be82008-07-31 17:17:14 +00006301- Apply security patches from Apple.
6302
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006303- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6304 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6305
Antoine Pitrou92f82162008-07-25 22:22:08 +00006306- Issue #1819: function calls with several named parameters are now on
6307 average 35% faster (as measured by pybench).
6308
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006309- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6310 the python debugger steps into a class statement: the free variables (local
6311 variables defined in an outer scope) would be deleted from the outer scope.
6312
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006313- Issue #2620: Overflow checking when allocating or reallocating memory
6314 was not always being done properly in some python types and extension
6315 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6316 all been updated to perform better checks and places in the code that
6317 would previously leak memory on the error path when such an allocation
6318 failed have been fixed.
6319
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006320Library
6321-------
6322
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006323- Issue #3612: Added some missing basic types in ctypes.wintypes.
6324
Benjamin Petersone977ad42008-08-20 01:42:01 +00006325- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6326 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6327
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006328- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6329 version reported by these tools does not necessarily follow the python
6330 version numbering scheme, so the module is less strict when parsing it.
6331
Nick Coghlanf70385a2008-08-18 12:42:46 +00006332- Issue #2235: Added Py3k warnings for types which will become unhashable
6333 under the stricter __hash__ inheritance rules in 3.0. Several types
6334 which did not meet the rules for hash invariants and were already
6335 unhashable in 3.0 have now been explicitly flagged as unhashable in
6336 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6337 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6338
Brett Cannon88f801d2008-08-18 00:46:22 +00006339- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6340 imported into the module but exposed as part of the module's API.
6341
Brett Cannon7b96f072008-08-18 00:41:11 +00006342- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6343
Brett Cannon46225e72008-08-18 00:36:52 +00006344- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6345
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006346- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6347
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006348- Issue #3575: Incremental decoder's decode function now takes bytearray
6349 by using 's*' instead of 't#'.
6350
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006351- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006352 fails unicode conversion on 2nd parameter. (windows only)
6353
Georg Brandl222e2082010-08-01 22:27:39 +00006354- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006355 in a redirect.
6356
Brett Cannonabe423e2008-08-16 21:47:07 +00006357- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006358 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006359
Facundo Batistaeb90b782008-08-16 14:44:07 +00006360- Issue #2776: fixed small issue when handling an URL with double slash
6361 after a 302 response in the case of not going through a proxy.
6362
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006363- Issue #2676: in the email package, content-type parsing was hanging on
6364 pathological input because of quadratic or exponential behaviour of a
6365 regular expression.
6366
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006367- Issue #3476: binary buffered reading through the new "io" library is now
6368 thread-safe.
6369
Brett Cannonbf3157b2008-08-14 05:00:03 +00006370- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6371 since mimetools itself is deprecated. Because modules are cached, all
6372 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6373
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006374- Issue #3134: shutil referenced undefined WindowsError symbol.
6375
Robert Schuppenies14646332008-08-10 11:01:53 +00006376- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6377 menu entries were not deleted.
6378
Brett Cannon83e81842008-08-09 23:30:55 +00006379- Copied the implementation of reduce() to _functools.reduce() to have a
6380 version that did not raise a DeprecationWarning under -3.
6381
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006382- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6383 a MemoryError rather than silently stop the iteration.
6384
Guido van Rossum59ce9012008-08-09 14:55:34 +00006385- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6386 to _sre.compile() will now be rejected. This should not affect anybody
6387 since the re.compile() function never generates invalid re-bytecode.
6388
Skip Montanaroa032bf42008-08-08 22:52:51 +00006389- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6390 upon first access it can be automatically initialized from the csv file if
6391 it wasn't initialized during instantiation.
6392
Brett Cannon3aa2a492008-08-06 22:28:09 +00006393- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6394 the reload() built-in has been removed.
6395
Brett Cannon7e30b672008-08-04 21:52:25 +00006396- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006397 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006398 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6399 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6400 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6401 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6402 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006403
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006404- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6405 raised an AttributeError.
6406
Benjamin Peterson01a24322008-07-28 23:35:27 +00006407- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006408 asking for a specific length. This problem only affected files opened
6409 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006410
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006411- Issue #3449: Update decimal module to use most recent specification
6412 (v. 1.68) and tests (v. 2.58) from IBM.
6413
Georg Brandl222e2082010-08-01 22:27:39 +00006414- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006415

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006417 on a closed shelf.
6418
Georg Brandlf9efabb2008-07-23 15:16:45 +00006419- Deprecate the "ast" parser function aliases.
6420
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006421- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6422
6423- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6424 invalid arguments.
6425
6426- Issue #3302: Fix several crashes when calling locale's gettext functions
6427 with None arguments.
6428
6429- Issue #3389: Allow resolving dotted names for handlers in logging
6430 configuration files.
6431
6432- Deprecate the sunaudio module for removal in Python 3.0.
6433
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006434- Issue #3394: zipfile.writestr sets external attributes when passed a
6435 file name rather than a ZipInfo instance, so files are extracted with
6436 mode 0600 rather than 000 under Unix.
6437
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006438- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6439 argument in python 2.5, this broke code that subclassed Popen to include its
6440 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6448-------------
6449
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006450- Issue #2235: the C API function PyObject_HashNotImplemented and its
6451 interaction with the tp_hash slot (added in 2.6b2) are now documented
6452
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006453- Issue #643841: The language reference now provides more detailed
6454 coverage of the lookup process for special methods. The disclaimers
6455 regarding lack of coverage of new-style classes have also been
6456 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006459What's New in Python 2.6 beta 2?
6460================================
6461
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006462*Release date: 17-Jul-2008*
6463
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006464Core and Builtins
6465-----------------
6466
Georg Brandl3e483f62008-07-16 22:57:41 +00006467- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6468 its methods now allow for items objects that can be converted to
6469 an integer using operator.index().
6470
Mark Dickinson64b7e502008-07-16 09:40:03 +00006471- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6472 produced a ValueError instead of giving the correct float.
6473
Eric Smitha5fa5a22008-07-16 00:11:49 +00006474- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6475 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6476
Mark Dickinson7103aa42008-07-15 19:08:33 +00006477- Issue #3008: the float type has a new instance method 'float.hex'
6478 and a new class method 'float.fromhex' to convert floating-point
6479 numbers to and from hexadecimal strings, respectively.
6480
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006481- Issue #2235: __hash__ is once again inherited by default. To allow
6482 collections.Hashable to remain meaningful in the presence of the
6483 default hash implementation (object.__hash__), it is now possible
6484 to explicit block inheritance of hash by setting __hash__=None at
6485 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6486 level.
6487
Nick Coghlanb028f502008-07-13 14:52:36 +00006488- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6489 the parent module cannot be found while performing an absolute import.
6490 This means that an incorrectly defined __package__ attribute will
6491 now only prevent relative imports in that module rather than causing
6492 all imports from that module to fail.
6493
Nick Coghlan14ff9942008-07-08 14:21:42 +00006494- Issue #2517: Allow unicode messages in Exceptions again by correctly
6495 bypassing the instance dictionary when looking up __unicode__ on
6496 new-style classes.
6497
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006498- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6499 set to a custom object whose write() method happens to install
6500 another file in sys.stdout.
6501
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006502- Issue #3088: Corrected a race condition in classes derived from
6503 threading.local: the first member set by a thread could be saved in
6504 another thread's dictionary.
6505
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006506- Issue #3004: Minor change to slice.indices(): the start and stop
6507 arguments are now treated identically, making the behaviour easier
6508 to describe and understand. For example, slice(None, -10,
6509 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6510 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6511 10, -1).
6512
Georg Brandl278fc502008-07-19 12:46:12 +00006513- Issue #3219: Calling a function with repeated keyword arguments,
6514 f(a=2, a=23), would not cause a syntax error. This was a regression
6515 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006516
Georg Brandl278fc502008-07-19 12:46:12 +00006517- Issue #2862: Make int and float freelist management consistent with
6518 other freelists. Changes their CompactFreeList apis into
6519 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006520

6523
Thomas Heller57adf222008-08-14 19:10:48 +00006524- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6525 api functions without holding the GIL, which could lead to a fatal
6526 error when they failed.
6527
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006528- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6537 ForkingPickler.register() to resolve conflict with ctypes.
6538
Vinay Sajip51e65192008-07-18 09:01:10 +00006539- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6542 a valid dlerror() message.
6543
Thomas Heller2bad6572008-07-15 17:19:50 +00006544- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6545 incomplete structure was created.

6962
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006963- On MacOS X it is now possible to install the framework in 64-bit
6964 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006965 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006966
6967 This is controlled by the configure argument ``--with-universal-archs``:
6968
6969 - ``--with-universal-archs=all``: install 4-way universal
6970
6971 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6972
6973 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6974
6975 This option should be used in combination with ``--enable-universalsdk=``.
6976
6977 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7014 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007015
Christian Heimese74c8f22008-04-19 02:23:57 +00007016- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7017
Georg Brandl3ee81df2008-05-17 18:14:43 +00007018- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7019 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007020

Georg Brandl3ee81df2008-05-17 18:14:43 +00007027- Issue #1631171: Re-implement the 'warnings' module in C (the
7028 original Python code has been kept as backup). This will allow for
7029 using the 'warning's machinery in such places as the parser where
7030 use of pure Python code is not possible. Both the ``showarning()``
7031 and ``formatwarning()`` gain an optional 'line' argument which is
7032 not called by default for backwards-compatibility reasons. Setting
7033 ``warnings.showwarning()`` to an implementation that lacks support
7034 for the ``line`` argument will raise a DeprecationWarning.

7058
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007059- The getpass module has been improved on Unix. It now uses /dev/tty
7060 by default and uses stderr instead of stdout. A GetPassWarning is
7061 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007062

Georg Brandl3ee81df2008-05-17 18:14:43 +00007076- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007077 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007097- Issue #2550: The approach used by client/server code for obtaining
7098 ports to listen on in network-oriented tests has been refined in an
7099 effort to facilitate running multiple instances of the entire
7100 regression test suite in parallel without issue.
7101 test_support.bind_port() has been fixed such that it will always
7102 return a unique port -- which wasn't always the case with the
7103 previous implementation, especially if socket options had been set
7104 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7105 new implementation of bind_port() will actually raise an exception
7106 if it is passed an AF_INET/SOCK_STREAM socket with either the
7107 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7108 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7109 the socket it's been passed. This currently only applies to
7110 Windows. This option prevents any other sockets from binding to the
7111 host/port we've bound to, thus removing the possibility of the
7112 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7113 when a second SOCK_STREAM socket binds and accepts to a host/port
7114 that's already been bound by another socket. The optional preferred
7115 port parameter to bind_port() has been removed. Under no
7116 circumstances should tests be hard coding ports!
7117
7118 test_support.find_unused_port() has also been introduced, which will
7119 pass a temporary socket object to bind_port() in order to obtain an
7120 unused port. The temporary socket object is then closed and
7121 deleted, and the port is returned. This method should only be used
7122 for obtaining an unused port in order to pass to an external program
7123 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7124 a parameter to a server-oriented class that doesn't give you direct
7125 access to the underlying socket used.
7126
7127 Finally, test_support.HOST has been introduced, which should be used
7128 for the host argument of any relevant socket calls (i.e. bind and
7129 connect).

7404-----------------
7405
Fred Drakea8ee94b2008-03-01 02:45:07 +00007406- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007407 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007408
Georg Brandlad61bc82008-02-23 15:11:18 +00007409- Issue #2067: file.__exit__() now calls subclasses' close() method.
7410
7411- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007412
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007413- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007414 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007415
Eric Smitha73fbe72008-02-23 03:09:44 +00007416- Added the future_builtins module, which contains hex() and oct().
7417 These are the PEP 3127 version of these functions, designed to be
7418 compatible with the hex() and oct() builtins from Python 3.0. They
7419 differ slightly in their output formats from the existing, unchanged
7420 Python 2.6 builtins. The expected usage of the future_builtins
7421 module is:
7422 from future_builtins import hex, oct
7423
Eric Smith7ef40bf2008-02-20 23:34:22 +00007424- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7425 exponents for exponents with absolute value < 100. Follows C99
7426 standard. This is a change on Windows, which would use 3 digits.
7427 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7428 so that any alterations it does to the resulting string will be
7429 available in stringlib/formatter.h (for float.__format__).
7430
Eric Smith5a3c1352008-02-19 13:21:56 +00007431- Implemented PEP 3101, Advanced String Formatting. This adds a new
7432 builtin format(); a format() method for str and unicode; a
7433 __format__() method to object, str, unicode, int, long, float, and
7434 datetime; the class string.Formatter; and the C API
7435 PyObject_Format().
7436
Georg Brandl3ee81df2008-05-17 18:14:43 +00007437- Fixed several potential crashes, all caused by specially crafted
7438 __del__ methods exploiting objects in temporarily inconsistent
7439 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007440
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007441- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007442 prevent a possible crash: an Abstract Base Class would try to access
7443 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007444
Georg Brandl3ee81df2008-05-17 18:14:43 +00007445- Fixed repr() and str() of complex numbers with infinity or nan as
7446 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007447
Georg Brandl3ee81df2008-05-17 18:14:43 +00007448- Clear all free lists during a gc.collect() of the highest generation
7449 in order to allow pymalloc to free more arenas. Python may give back
7450 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007451
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452- Issue #2045: Fix an infinite recursion triggered when printing a
7453 subclass of collections.defaultdict, if its default_factory is set
7454 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007455
Christian Heimesf75dbef2008-02-08 00:11:31 +00007456- Fixed a minor memory leak in dictobject.c. The content of the free
7457 list was not freed on interpreter shutdown.
7458
Georg Brandl21e99f42010-03-07 15:23:59 +00007459- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007460 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007461
Georg Brandl3ee81df2008-05-17 18:14:43 +00007462- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7463 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007464 to compact the internal free lists of pre-allocted ints and floats.
7465
Georg Brandl3ee81df2008-05-17 18:14:43 +00007466- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7467 calls. Python expected the return type int but the fork familie
7468 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007469
Georg Brandl3ee81df2008-05-17 18:14:43 +00007470- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7471 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007472
Georg Brandl3ee81df2008-05-17 18:14:43 +00007473- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7474 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007475
Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7477 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007478
Georg Brandl3ee81df2008-05-17 18:14:43 +00007479- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7480 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007481
Georg Brandl3ee81df2008-05-17 18:14:43 +00007482- Patch #1473257: generator objects gain a gi_code attribute. This is
7483 the same object as the func_code attribute of the function that
7484 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007485
Georg Brandl3ee81df2008-05-17 18:14:43 +00007486- Issue #1920: "while 0" statements were completely removed by the
7487 compiler, even in the presence of an "else" clause, which is
7488 supposed to be run when the condition is false. Now the compiler
7489 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007490
Guido van Rossumeead05f2008-01-24 18:21:02 +00007491- A few crashers fixed: weakref_in_del.py (issue #1377858);
7492 loosing_dict_ref.py (issue #1303614, test67.py);
7493 borrowed_ref_[34].py (not in tracker).
7494
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007495- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007496 suppressed while an extension is loaded by calling SetErrorMode in
7497 dynload_win.c. The error is still reported properly.
7498
Georg Brandl3ee81df2008-05-17 18:14:43 +00007499- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007500 several extension methods and modules do not work without unicode
7501 support.
7502
Georg Brandl26543b12008-01-21 18:36:51 +00007503- Issue #1882: when compiling code from a string, encoding cookies in the
7504 second line of code were not always recognized correctly.
7505
Georg Brandl14404b62008-01-19 19:27:05 +00007506- Issue #1679: "0x" was taken as a valid integer literal.
7507
Georg Brandl6caad7d2008-01-26 14:19:22 +00007508- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007509 added.
7510
Christian Heimesc94e2b52008-01-14 04:13:37 +00007511- sys.float_info / PyFloat_GetInfo: The floating point information
7512 object was converted from a dict to a specialized structseq object.
7513
Georg Brandl3ee81df2008-05-17 18:14:43 +00007514- Patch #1816: Added sys.flags structseq. It exposes the status of
7515 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007516
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Objects/structseq.c: Implemented new structseq representation. The
7518 patch makes structseqs (e.g. the return value of os.stat) more
7519 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007520
Georg Brandl3ee81df2008-05-17 18:14:43 +00007521- Patch #1700288: added a type attribute cache that caches method
7522 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007523
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007524- Bug #1776: __import__() no longer accepts filenames on any platform.
7525 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007526

7528
Georg Brandl3ee81df2008-05-17 18:14:43 +00007529- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7530 envvar and sys.dont_write_bytecode attribute. All these can be set
7531 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007532
Georg Brandl3ee81df2008-05-17 18:14:43 +00007533- Improve some exception messages when Windows fails to load an
7534 extension module. Now we get for example '%1 is not a valid Win32
7535 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007536
Georg Brandl3ee81df2008-05-17 18:14:43 +00007537- Bug #1481296: Fixed long(float('nan')) != 0L.

7540 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007541
Christian Heimes0a8143f2007-12-18 23:22:54 +00007542- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007543 and INF. float("nan"), float("inf") and float("-inf") now work on
7544 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007545
Georg Brandl3ee81df2008-05-17 18:14:43 +00007546- Compiler now generates simpler and faster code for dictionary
7547 literals. The oparg for BUILD_MAP now indicates an estimated
7548 dictionary size. There is a new opcode, STORE_MAP, for adding
7549 entries to the dictionary.

7581 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007582
Georg Brandl3ee81df2008-05-17 18:14:43 +00007583- Issue #1265: Fix a problem with sys.settrace, if the tracing
7584 function uses a generator expression when at the same time the
7585 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007586
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007587- sets and frozensets now have an isdisjoint() method.

7592
Georg Brandl21e99f42010-03-07 15:23:59 +00007593- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007594 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7595 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007596
Georg Brandl3ee81df2008-05-17 18:14:43 +00007597- Issue #1686386: Tuple's tp_repr did not take into account the
7598 possibility of having a self-referential tuple, which is possible
7599 from C code. Nor did object's tp_str consider that a type's tp_str
7600 could do something that could lead to an inifinite recursion.
7601 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7602 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007603
Georg Brandl3ee81df2008-05-17 18:14:43 +00007604- Issue #1164: It was possible to trigger deadlock when using the
7605 'print' statement to write to a file since the GIL was not released
7606 as needed. Now PyObject_Print() does the right thing along with
7607 various tp_print implementations of the built-in types and those in
7608 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007610- Issue #1147: Exceptions were directly allowing string exceptions in
7611 their throw() method even though string exceptions no longer
7612 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007614- Issue #1096: Prevent a segfault from getting the repr of a very
7615 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00007617- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007618 PyObject_Call() never calling back out to Python code to trigger
7619 recursion depth updates/checks. Required the creation of a static
7620 RuntimeError instance in case normalizing an exception put the
7621 recursion check value past its limit. Fixes crashers
7622 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007637- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007638 __*__ attributes. (Some already existed, e.g., __doc__ and
7639 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007640
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007641- Add -3 option to the interpreter to warn about features that are

7643
Georg Brandl2134e752007-05-21 20:34:16 +00007644- Patch #1686487: you can now pass any mapping after '**' in function
7645 calls.
7646
Collin Winter62903052007-05-18 23:11:24 +00007647- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007648 "except E as target:". This is to provide forwards compatibility
7649 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007650
Brett Cannon229cee22007-05-05 01:34:02 +00007651- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007656- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007657 setting a plain string, ie don't expand to single letter identifiers.
7658
Raymond Hettinger13936692007-04-11 18:40:58 +00007659- Request #1191699: Slices can now be pickled.
7660
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007661- Request #1193128: str.translate() now allows a None argument for
7662 translations that only remove characters without re-mapping the
7663 remaining characters.
7664
Georg Brandl5cb76c12007-03-21 09:00:39 +00007665- Patch #1682205: a TypeError while unpacking an iterable is no longer

7667
Neal Norwitzaa754b72007-03-21 06:39:48 +00007668- Remove unused file Python/fmod.c.
7669
Guido van Rossum143b5642007-03-23 04:58:42 +00007670- Bug #1683368: The object.__init__() and object.__new__() methods are
7671 now stricter in rejecting excess arguments. The only time when
7672 either allows excess arguments is when it is not overridden and the
7673 other one is. For backwards compatibility, when both are
7674 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007675 warning later). Also, type.__init__() insists on the same signature
7676 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007677
Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7679 object to complex using its __complex__() method before falling back
7680 to the __float__() method. Therefore, the functions in the cmath
7681 module now can operate on objects that define a __complex__()
7682 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007700- Bug #1678647: write a newline after printing an exception in any
7701 case, even when converting the value to a string failed.
7702
Georg Brandl871f1bc2007-03-12 13:17:36 +00007703- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007704 its argument, if it exists. If not, it will work like before. This
7705 allows customizing the output of dir() in the presence of a
7706 __getattr__().

7715 parthensized forms. This means complex(repr(x)) now works instead of
7716 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007717
Georg Brandlaa2321b2007-03-07 00:40:28 +00007718- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007719 makes the filenames the warning module prints much more sensible
7720 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007721

Georg Brandl0fca97a2007-03-05 22:28:08 +00007733- Patch #1674228: when assigning a slice (old-style), check for the
7734 sq_ass_slice instead of the sq_slice slot.
7735
Georg Brandl3ee81df2008-05-17 18:14:43 +00007736- When printing an unraisable error, don't print exceptions. before

8347 Python would crash instead of raising an error.
8348

8364 accepted in TestSuite.addTest(). This should cause no
8365 incompatibility since it never made sense with ordinary subclasses
8366 -- the failure just occurred later, with a more cumbersome
8367 exception.

8645 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008646
Georg Brandl3ee81df2008-05-17 18:14:43 +00008647- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008648 that the SMTP.starttls() caller no longer needs to call ehlo()
8649 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008650 does not claim to support starttls. Adds the
8651 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008750 time so that opening a database previously created with the DB_DUP
8751 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8752 opens. Specifically: dictionary assignment to a DB object will
8753 replace all values for a given key when the database allows
8754 duplicate values. DB users should use DB.put(k, v) when they want
8755 to store duplicates; not DB[k] = v.

8762 characters with ASCII value less than 32. Also, it correctly quotes
8763 dots only if they occur on a single line, as opposed to the previous
8764 behavior of quoting dots if they are the second character of any
8765 line.

9097-----
9098
Georg Brandl3ee81df2008-05-17 18:14:43 +00009099- Unified naming convention for free lists and their limits. All free
9100 lists in Object/ are named ``free_list``, the counter ``numfree``
9101 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9102 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009103
Georg Brandl3ee81df2008-05-17 18:14:43 +00009104- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9105 to ``PyTuple_SetItem``, it can be used to populate a brand new
9106 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009107
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009108- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009110- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9111 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9112 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009113
9114- Patch #1720595: add T_BOOL to the range of structmember types.
9115
9116- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9117 ``PyFloat_GetInfo()`` to the float API.
9118
Georg Brandl3ee81df2008-05-17 18:14:43 +00009119- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9120 of w# format code incorrectly truncated the length to an int, even
9121 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9122 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009123
Georg Brandl3ee81df2008-05-17 18:14:43 +00009124- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9125 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009126
Georg Brandl3ee81df2008-05-17 18:14:43 +00009127- PEP 3123: Provide forward compatibility with Python 3.0, while
9128 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9129 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009130
Georg Brandl3ee81df2008-05-17 18:14:43 +00009131- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9132 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009133
9134- Patch #1733960: Allow T_LONGLONG to accept ints.
9135
9136- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9137

9141
9142- Fix some leftovers from the conversion from int to Py_ssize_t
9143 (relevant to strings and sequences of more than 2**31 items).
9144
9145- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9146 outside of pystate.c and should not be necessary.
9147
Georg Brandl3ee81df2008-05-17 18:14:43 +00009148- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9149 absolute imports. In earlier versions they might have used relative
9150 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009151
Georg Brandl3ee81df2008-05-17 18:14:43 +00009152- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9153 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009154
Georg Brandl3ee81df2008-05-17 18:14:43 +00009155- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9156 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009162- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9163 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9164 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9165 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009166
Georg Brandl3ee81df2008-05-17 18:14:43 +00009167- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009180- Removed the macfs module. It had been deprecated since Python 2.5.
9181 This lead to the deprecation of macostools.touched() as it relied
9182 solely on macfs and was a no-op under OS X.
