Ned Deily18fae3f2013-01-31 01:24:55 -08001734- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1735 In particular, fix extension module build failures when trying to use
1736 32-bit-only installer Pythons on systems with Xcode 4 (currently
1737 OS X 10.8, 10.7, and optionally 10.6).
1738 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1739 * Since Xcode 4 removes ppc support, extension module builds now
1740 check for ppc compiler support and by default remove ppc and
1741 ppc64 archs when they are not available.
1742 * Extension module builds now revert to using system installed
1743 headers and libs (/usr and /System/Library) if the SDK used
1744 to build the interpreter is not installed or has moved.
1745 * Try to avoid building extension modules with deprecated
1746 and problematic Apple llvm-gcc compiler. If original compiler
1747 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002098- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2099 int.__pow__. These overflow checks were causing int.__pow__ to produce
2100 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002101 compiler optimizing the check away. Also fix similar overflow checks
2102 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2103 bugs caused test failures with recent versions of Clang.

2115 cleared by the garbage collector. This fixes a segfault when an instance
2116 and its type get caught in a reference cycle, and the instance's
2117 deallocator calls one of the methods on the type (e.g. when subclassing
2118 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +02002127 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2128 raw_input() interrupted by CTRL+c.
2129
Łukasz Langa7a153902011-10-18 17:16:00 +02002130- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01002171- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002172 has left two versions of customize_compiler, the original in
2173 distutils.sysconfig and another copy in distutils.ccompiler, with some
2174 parts of distutils calling one and others using the other.

2176 is the case in 3.x.
2177
Ned Deily0d0ea482012-02-10 12:59:06 +01002178- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2179 Distutils-based packages with C extension modules may fail because
2180 Apple has removed gcc-4.2, the version used to build python.org
2181 64-bit/32-bit Pythons. If the user does not explicitly override
2182 the default C compiler by setting the CC environment variable,
2183 Distutils will now attempt to compile extension modules with clang
2184 if gcc-4.2 is required but not found. Also as a convenience, if
2185 the user does explicitly set CC, substitute its value as the default
2186 compiler in the Distutils LDSHARED configuration variable for OS X.
2187 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2188 SDK, neither of which are available in Xcode 4. This change does not
2189 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002439- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2440 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2441 interpreter process. This could cause failures in non-Distutils subprocesses
2442 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002443 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002444 deployment target only in the environment of each build subprocess. It is
2445 still possible to globally override the default by setting
2446 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2447 greater or equal to the default value, the value with which the interpreter
2448 was built.

2477 updating the check interval, so if the user decreases the check interval,
2478 the ticker doesn't have to wind down to zero from the old starting point
2479 before the new interval takes effect. And if the user increases the
2480 interval, it makes sure the new limit takes effect right away rather have an
2481 early task switch before recognizing the new interval.

3462 This prevents user-created self-referencing ordered dictionaries from
3463 becoming permanently uncollectable GC garbage. The downside is that

3465 GC collection rather than freeing memory immediately when the refcnt drops
3466 to zero.

3923
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003924- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3925 start byte and the continuation byte(s) are now considered invalid, instead
3926 of the number of bytes specified by the start byte.
3927 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3928 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3929 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003938- Issue #8748: Fix two issues with comparisons between complex and integer
3939 objects. (1) The comparison could incorrectly return True in some cases
3940 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3941 (2) The comparison raised an OverflowError for large integers, leading
3942 to unpredictable exceptions when combining integers and complex objects
3943 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003945- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004082- Issue #1533: Fix inconsistency in range function argument processing: any
4083 non-float non-integer argument is now converted to an integer (if possible)
4084 using its __int__ method. Previously, only small arguments were treated this
4085 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00004136- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4137 operation raises multiple signals and more than one of those signals is
4138 trapped, the specification determines the order in which the signals should be
4139 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004284- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004285 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4286 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4287 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +00004305*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004306
4307Core and Builtins
4308-----------------
4309
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004310- Issue #7301: Add environment variable $PYTHONWARNINGS.
4311
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004312- Issue #8329: Don't return the same lists from select.select when no fds are
4313 changed.
4314
Georg Brandlfee0f442010-05-22 21:26:21 +00004315- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004316 on 64-bit machines. The shift count for either left or right shift is
4317 permitted to be up to sys.maxsize.
4318
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004319- Ensure that tokenization of identifiers is not affected by locale.
4320
Georg Brandlfee0f442010-05-22 21:26:21 +00004321- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004322
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004323- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4324
Georg Brandlfee0f442010-05-22 21:26:21 +00004325- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4326 with a non-empty format string. This is an effort to future-proof user
4327 code. If a derived class does not currently implement __format__ but later
4328 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004329 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004330 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004331
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004332- Issue #8268: Old-style classes (not just instances) now support weak
4333 references.
4334
Georg Brandlfee0f442010-05-22 21:26:21 +00004335- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4336 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004337
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004338- Issue #1583863: An unicode subclass can now override the __unicode__ method

4341 arguments to a function correct.
4342
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004343- Issue #8164: Don't allow lambda functions to have a docstring.
4344
Victor Stinner66644262010-03-10 22:30:19 +00004345- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004346 (SIGINT). If an error occurs while importing the site module, the error is
4347 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004348 module.
4349
Collin Winter001a3952010-03-18 21:54:01 +00004350- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00004355- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4356
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004357- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004358 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4359 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00004361- Issue #8310: Allow dis to examine new style classes.
4362
Georg Brandlfee0f442010-05-22 21:26:21 +00004363- Issue #8257: The Decimal construct now accepts a float instance directly,
4364 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004365
4366 >>> Decimal(1.1)
4367 Decimal('1.100000000000000088817841970012523233890533447265625')
4368
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004369- collections.Counter() now supports a subtract() method.
4370
Georg Brandlfee0f442010-05-22 21:26:21 +00004371- The functools module now has a total_ordering() class decorator to simplify
4372 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004373
Georg Brandlfee0f442010-05-22 21:26:21 +00004374- The functools module also adds cmp_to_key() as a tool to transition old-style
4375 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004376
Georg Brandlfee0f442010-05-22 21:26:21 +00004377- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4378 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004379
Georg Brandlfee0f442010-05-22 21:26:21 +00004380- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4381 InvalidOperation instead of returning False. (Comparisons involving a quiet
4382 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4383 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004384
Georg Brandlfee0f442010-05-22 21:26:21 +00004385- Issue #2531: Comparison operations between floats and Decimal instances now
4386 return a result based on the numeric values of the operands; previously they
4387 returned an arbitrary result based on the relative ordering of id(float) and
4388 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004389
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004390- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004391 argument `-` which tells it to read files to compile from stdin. Each line is
4392 read on demand and the named file is compiled immediately. (Original patch by
4393 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004394
Georg Brandlfee0f442010-05-22 21:26:21 +00004395- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4396 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004398- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4399 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004400 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004401
Georg Brandlfee0f442010-05-22 21:26:21 +00004402- Comparisons using one of <, <=, >, >= between a complex instance and a
4403 Fractions instance now raise TypeError instead of returning True/False. This
4404 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4405 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004406
Michael Foorde6410c52010-03-29 20:04:23 +00004407- Addition of ``WeakSet`` to the ``weakref`` module.

4415
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004416- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004417 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4418 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004419
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004420- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4421 deprecated.
4422
Georg Brandlfee0f442010-05-22 21:26:21 +00004423- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4424 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004425

4430 existing at the same time, causing a Unicode error when configuration code
4431 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004432
Georg Brandlfee0f442010-05-22 21:26:21 +00004433- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4434 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00004436- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4437 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4438 reads and writes are always retried by OpenSSL itself.

4446 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00004447
Matthias Klose8b411682010-03-16 10:48:52 +00004448- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004460- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004461 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4462 log file to compute the next rollover time. If the log file does not exist,
4463 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004464
Georg Brandlba83f822010-03-14 09:50:54 +00004465- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00004473- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4474 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4475 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004504- Issue #8300: When passing a non-integer argument to struct.pack with any
4505 integer format code, struct.pack first attempts to convert the non-integer
4506 using its __index__ method. If that method is non-existent or raises
4507 TypeError it goes on to try the __int__ method, as described below.
4508
Georg Brandlba83f822010-03-14 09:50:54 +00004509- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4510 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4511 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004512 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4513 inconsistent: __int__ was used for some integer codes but not for others, and
4514 the set of integer codes for which it was used differed between native packing
4515 and standard packing.)

4930 These functions and methods now raise TypeError instead. The majority of the

4932 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4933 and many unicode/str methods.

4949 internal representation of a long.

5099 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005100

5102 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005103
Georg Brandlba83f822010-03-14 09:50:54 +00005104- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5105 1e-100 used to raise OverflowError, but now gives the requested 120
5106 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005114
Georg Brandlba83f822010-03-14 09:50:54 +00005115- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5116 decimal string that's guaranteed to round back to x under correct rounding
5117 (with round-half-to-even rounding mode). Previously it gave a string based on
5118 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5119 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5120 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005121
Georg Brandlba83f822010-03-14 09:50:54 +00005122- Issue #7117: On almost all platforms: float-to-string and string-to-float
5123 conversions within Python are now correctly rounded. Places these conversions
5124 occur include: str for floats and complex numbers; the float and complex
5125 constructors; old-style and new-style numeric formatting; serialization and
5126 deserialization of floats and complex numbers using marshal, pickle and json;
5127 parsing of float and imaginary literals in Python code; Decimal-to-float
5128 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005129
Georg Brandlba83f822010-03-14 09:50:54 +00005130 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5131 providing correctly-rounded strtod and dtoa C functions. This code is
5132 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5133 the C compiler. There may be a small number of platforms on which correct
5134 operation of this code cannot be guaranteed, so the code is not used: notably,
5135 this applies to platforms where the C double format is not IEEE 754 binary64,
5136 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5137 and Python's configure script is unable to determine how to change the FPU
5138 precision. On these platforms conversions use the platform strtod and dtoa,
5139 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005140
Georg Brandlba83f822010-03-14 09:50:54 +00005141- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5142 uses the correctly-rounded string <-> float conversions described above (when
5143 available), and so produces correctly rounded results that will display nicely
5144 under the float repr. There are two related small changes: (1) round now
5145 accepts any class with an ``__index__()`` method for its second argument (but
5146 no longer accepts floats for the second argument), and (2) an excessively
5147 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5148 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005295- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5296 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5297 but with at least one decimal point and with a default precision
5298 of 12. Previously, the behavior the same but with a default precision of 6.
5299 This more closely matches ``str()``, and reduces surprises when adding
5300 alignment flags to the empty presentation type. This also affects the new
5301 complex.__format__ in the same way.

5498
Georg Brandlba83f822010-03-14 09:50:54 +00005499- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5500 file objects with closefd=False. The file descriptor is still kept open but
5501 the file object behaves like a closed file. The ``FileIO`` object also got a
5502 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005522- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005525- On windows, ``os.chdir()`` given unicode was not working if
5526 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5527 this code path is really executed because I cannot move to such directory on
5528 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005530- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5531 element is temporarily replaced with an equivalent frozenset. But the
5532 eventual KeyError would always report the empty ``frozenset()`` as the missing
5533 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005553- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5554 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5555 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5556 of using the replace error handler in PyUnicode_DecodeUTF8().
5557
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005558- Issue #3739: The unicode-internal encoder now reports the number of characters

5560
Georg Brandlba83f822010-03-14 09:50:54 +00005561- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5563 gives improved memory leak detection when running under Valgrind, while taking
5564 advantage of pymalloc at other times.

6810 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006811 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6812 the tests if DISPLAY is defined but can't be used.

6933
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006934- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6935 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6936 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6937 ``printf`` function, whereas PyString_FromFormat has an independent
6938 implementation and uses "%zd" on all platforms for size_t values.
6939 This makes a difference on win64, where ``printf`` needs "%Id" to display
6940 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006957 was correctly parsed but parsing of subsequent arguments failed.
6958
Vinay Sajip35e3b032008-09-01 14:33:59 +00006959- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006960 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6961 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6963 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6964 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007103What's New in Python 2.6 beta 3?
7104================================
7105
Barry Warsaw07a4a382008-08-21 01:15:08 +00007106*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007107
7108Core and Builtins
7109-----------------
7110
Guido van Rossumf8402962008-08-20 15:01:50 +00007111- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7112 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7113 extensions do not automatically benefit from the class attribute
7114 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7115 to their tp_flags field if they care. This is a backwards
7116 compatibility feature; in 3.0, all types will use the cache by
7117 default.
7118
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007119- Keyword arguments can now follow starred arguments. (``f(a, *args,
7120 keyword=23)`` is now valid syntax.)
7121
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007122- ctypes function pointers that are COM methods have a boolean True
7123 value again.
7124
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007125- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7126 by denying s# to parse objects that have a releasebuffer procedure,
7127 and introducing s*.
7128
Georg Brandl1e13ea92008-08-11 09:07:59 +00007129- Issue #3537: Fix an assertion failure when an empty but presized dict
7130 object was stored in the freelist.
7131
Mark Dickinsonb6467572008-08-04 21:30:09 +00007132- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7133 ValueError consistently across platforms.
7134
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007135- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7136 (64bit Unix, for example), unichr() would truncate its argument and return
7137 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7138
Neal Norwitze7d8be82008-07-31 17:17:14 +00007139- Apply security patches from Apple.
7140
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007141- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7142 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7143
Antoine Pitrou92f82162008-07-25 22:22:08 +00007144- Issue #1819: function calls with several named parameters are now on
7145 average 35% faster (as measured by pybench).
7146
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007147- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7148 the python debugger steps into a class statement: the free variables (local
7149 variables defined in an outer scope) would be deleted from the outer scope.
7150
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007151- Issue #2620: Overflow checking when allocating or reallocating memory
7152 was not always being done properly in some python types and extension
7153 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7154 all been updated to perform better checks and places in the code that
7155 would previously leak memory on the error path when such an allocation
7156 failed have been fixed.
7157
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007158Library
7159-------
7160
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007161- Issue #3612: Added some missing basic types in ctypes.wintypes.
7162
Benjamin Petersone977ad42008-08-20 01:42:01 +00007163- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7164 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7165
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007166- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7167 version reported by these tools does not necessarily follow the python
7168 version numbering scheme, so the module is less strict when parsing it.
7169
Nick Coghlanf70385a2008-08-18 12:42:46 +00007170- Issue #2235: Added Py3k warnings for types which will become unhashable
7171 under the stricter __hash__ inheritance rules in 3.0. Several types
7172 which did not meet the rules for hash invariants and were already
7173 unhashable in 3.0 have now been explicitly flagged as unhashable in
7174 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7175 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7176
Brett Cannon88f801d2008-08-18 00:46:22 +00007177- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7178 imported into the module but exposed as part of the module's API.
7179
Brett Cannon7b96f072008-08-18 00:41:11 +00007180- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7181
Brett Cannon46225e72008-08-18 00:36:52 +00007182- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7183
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007184- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7185
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007186- Issue #3575: Incremental decoder's decode function now takes bytearray
7187 by using 's*' instead of 't#'.
7188
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007189- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007190 fails unicode conversion on 2nd parameter. (windows only)
7191
Georg Brandl222e2082010-08-01 22:27:39 +00007192- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007193 in a redirect.
7194
Brett Cannonabe423e2008-08-16 21:47:07 +00007195- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007196 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007197
Facundo Batistaeb90b782008-08-16 14:44:07 +00007198- Issue #2776: fixed small issue when handling an URL with double slash
7199 after a 302 response in the case of not going through a proxy.
7200
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007201- Issue #2676: in the email package, content-type parsing was hanging on
7202 pathological input because of quadratic or exponential behaviour of a
7203 regular expression.
7204
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007205- Issue #3476: binary buffered reading through the new "io" library is now
7206 thread-safe.
7207
Brett Cannonbf3157b2008-08-14 05:00:03 +00007208- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7209 since mimetools itself is deprecated. Because modules are cached, all
7210 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7211
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007212- Issue #3134: shutil referenced undefined WindowsError symbol.
7213
Robert Schuppenies14646332008-08-10 11:01:53 +00007214- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7215 menu entries were not deleted.
7216
Brett Cannon83e81842008-08-09 23:30:55 +00007217- Copied the implementation of reduce() to _functools.reduce() to have a
7218 version that did not raise a DeprecationWarning under -3.
7219
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007220- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7221 a MemoryError rather than silently stop the iteration.
7222
Guido van Rossum59ce9012008-08-09 14:55:34 +00007223- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7224 to _sre.compile() will now be rejected. This should not affect anybody
7225 since the re.compile() function never generates invalid re-bytecode.
7226
Skip Montanaroa032bf42008-08-08 22:52:51 +00007227- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7228 upon first access it can be automatically initialized from the csv file if
7229 it wasn't initialized during instantiation.
7230
Brett Cannon3aa2a492008-08-06 22:28:09 +00007231- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7232 the reload() built-in has been removed.
7233
Brett Cannon7e30b672008-08-04 21:52:25 +00007234- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007235 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007236 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7237 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7238 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7239 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7240 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007241
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007242- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7243 raised an AttributeError.
7244
Benjamin Peterson01a24322008-07-28 23:35:27 +00007245- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007246 asking for a specific length. This problem only affected files opened
7247 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007248
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007249- Issue #3449: Update decimal module to use most recent specification
7250 (v. 1.68) and tests (v. 2.58) from IBM.
7251
Georg Brandl222e2082010-08-01 22:27:39 +00007252- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007253

Raymond Hettinger8c664e82008-07-25 18:43:33 +00007255 on a closed shelf.
7256
Georg Brandlf9efabb2008-07-23 15:16:45 +00007257- Deprecate the "ast" parser function aliases.
7258
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007259- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7260
7261- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7262 invalid arguments.
7263
7264- Issue #3302: Fix several crashes when calling locale's gettext functions
7265 with None arguments.
7266
7267- Issue #3389: Allow resolving dotted names for handlers in logging
7268 configuration files.
7269
7270- Deprecate the sunaudio module for removal in Python 3.0.
7271
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007272- Issue #3394: zipfile.writestr sets external attributes when passed a
7273 file name rather than a ZipInfo instance, so files are extracted with
7274 mode 0600 rather than 000 under Unix.
7275
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007276- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7277 argument in python 2.5, this broke code that subclassed Popen to include its
7278 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7286-------------
7287
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007288- Issue #2235: the C API function PyObject_HashNotImplemented and its
7289 interaction with the tp_hash slot (added in 2.6b2) are now documented
7290
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007291- Issue #643841: The language reference now provides more detailed
7292 coverage of the lookup process for special methods. The disclaimers
7293 regarding lack of coverage of new-style classes have also been
7294 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007297What's New in Python 2.6 beta 2?
7298================================
7299
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007300*Release date: 17-Jul-2008*
7301
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007302Core and Builtins
7303-----------------
7304
Georg Brandl3e483f62008-07-16 22:57:41 +00007305- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7306 its methods now allow for items objects that can be converted to
7307 an integer using operator.index().
7308
Mark Dickinson64b7e502008-07-16 09:40:03 +00007309- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7310 produced a ValueError instead of giving the correct float.
7311
Eric Smitha5fa5a22008-07-16 00:11:49 +00007312- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7313 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7314
Mark Dickinson7103aa42008-07-15 19:08:33 +00007315- Issue #3008: the float type has a new instance method 'float.hex'
7316 and a new class method 'float.fromhex' to convert floating-point
7317 numbers to and from hexadecimal strings, respectively.
7318
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007319- Issue #2235: __hash__ is once again inherited by default. To allow
7320 collections.Hashable to remain meaningful in the presence of the
7321 default hash implementation (object.__hash__), it is now possible
7322 to explicit block inheritance of hash by setting __hash__=None at
7323 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7324 level.
7325
Nick Coghlanb028f502008-07-13 14:52:36 +00007326- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7327 the parent module cannot be found while performing an absolute import.
7328 This means that an incorrectly defined __package__ attribute will
7329 now only prevent relative imports in that module rather than causing
7330 all imports from that module to fail.
7331
Nick Coghlan14ff9942008-07-08 14:21:42 +00007332- Issue #2517: Allow unicode messages in Exceptions again by correctly
7333 bypassing the instance dictionary when looking up __unicode__ on
7334 new-style classes.
7335
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007336- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7337 set to a custom object whose write() method happens to install
7338 another file in sys.stdout.
7339
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007340- Issue #3088: Corrected a race condition in classes derived from
7341 threading.local: the first member set by a thread could be saved in
7342 another thread's dictionary.
7343
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007344- Issue #3004: Minor change to slice.indices(): the start and stop
7345 arguments are now treated identically, making the behaviour easier
7346 to describe and understand. For example, slice(None, -10,
7347 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7348 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7349 10, -1).
7350
Georg Brandl278fc502008-07-19 12:46:12 +00007351- Issue #3219: Calling a function with repeated keyword arguments,
7352 f(a=2, a=23), would not cause a syntax error. This was a regression
7353 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007354
Georg Brandl278fc502008-07-19 12:46:12 +00007355- Issue #2862: Make int and float freelist management consistent with
7356 other freelists. Changes their CompactFreeList apis into
7357 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007358

Thomas Heller57adf222008-08-14 19:10:48 +00007362- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7363 api functions without holding the GIL, which could lead to a fatal
7364 error when they failed.
7365
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007366- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7375 ForkingPickler.register() to resolve conflict with ctypes.
7376
Vinay Sajip51e65192008-07-18 09:01:10 +00007377- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

7380 a valid dlerror() message.
7381
Thomas Heller2bad6572008-07-15 17:19:50 +00007382- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7383 incomplete structure was created.
7384

7798
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007799- On MacOS X it is now possible to install the framework in 64-bit
7800 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007801 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007802
7803 This is controlled by the configure argument ``--with-universal-archs``:
7804
7805 - ``--with-universal-archs=all``: install 4-way universal
7806
7807 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7808
7809 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7810
7811 This option should be used in combination with ``--enable-universalsdk=``.
7812
7813 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7849 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007850
Christian Heimese74c8f22008-04-19 02:23:57 +00007851- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7852
Georg Brandl3ee81df2008-05-17 18:14:43 +00007853- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7854 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007855

Georg Brandl3ee81df2008-05-17 18:14:43 +00007862- Issue #1631171: Re-implement the 'warnings' module in C (the
7863 original Python code has been kept as backup). This will allow for
7864 using the 'warning's machinery in such places as the parser where
7865 use of pure Python code is not possible. Both the ``showarning()``
7866 and ``formatwarning()`` gain an optional 'line' argument which is
7867 not called by default for backwards-compatibility reasons. Setting
7868 ``warnings.showwarning()`` to an implementation that lacks support
7869 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00007891- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00007892 reference to themselves.
7893
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007894- The getpass module has been improved on Unix. It now uses /dev/tty
7895 by default and uses stderr instead of stdout. A GetPassWarning is
7896 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007897

7908 implementation detail of the public ``types`` module, has been
7909 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00007910
Georg Brandl3ee81df2008-05-17 18:14:43 +00007911- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007912 extension modules between 32 and 64 bit platforms. See the distutls
7913 build documentation for more information.

7925 so the controlled environment will more closely mirror the typical
7926 script environment. This supports setup.py scripts that refer to
7927 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- Issue #2550: The approach used by client/server code for obtaining
7933 ports to listen on in network-oriented tests has been refined in an
7934 effort to facilitate running multiple instances of the entire
7935 regression test suite in parallel without issue.
7936 test_support.bind_port() has been fixed such that it will always
7937 return a unique port -- which wasn't always the case with the
7938 previous implementation, especially if socket options had been set
7939 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7940 new implementation of bind_port() will actually raise an exception
7941 if it is passed an AF_INET/SOCK_STREAM socket with either the
7942 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7943 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7944 the socket it's been passed. This currently only applies to
7945 Windows. This option prevents any other sockets from binding to the
7946 host/port we've bound to, thus removing the possibility of the
7947 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7948 when a second SOCK_STREAM socket binds and accepts to a host/port
7949 that's already been bound by another socket. The optional preferred
7950 port parameter to bind_port() has been removed. Under no
7951 circumstances should tests be hard coding ports!
7952
7953 test_support.find_unused_port() has also been introduced, which will
7954 pass a temporary socket object to bind_port() in order to obtain an
7955 unused port. The temporary socket object is then closed and
7956 deleted, and the port is returned. This method should only be used
7957 for obtaining an unused port in order to pass to an external program
7958 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7959 a parameter to a server-oriented class that doesn't give you direct
7960 access to the underlying socket used.
7961
7962 Finally, test_support.HOST has been introduced, which should be used
7963 for the host argument of any relevant socket calls (i.e. bind and
7964 connect).

7966 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7969 test_asynchat and test_socket_ssl.
7970
Georg Brandl3ee81df2008-05-17 18:14:43 +00007971 It is now possible for multiple instances of the regression test
7972 suite to run in parallel without issue.

8240
Fred Drakea8ee94b2008-03-01 02:45:07 +00008241- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008242 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008243
Georg Brandlad61bc82008-02-23 15:11:18 +00008244- Issue #2067: file.__exit__() now calls subclasses' close() method.
8245
8246- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008247
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008248- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008249 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008250
Eric Smitha73fbe72008-02-23 03:09:44 +00008251- Added the future_builtins module, which contains hex() and oct().
8252 These are the PEP 3127 version of these functions, designed to be
8253 compatible with the hex() and oct() builtins from Python 3.0. They
8254 differ slightly in their output formats from the existing, unchanged
8255 Python 2.6 builtins. The expected usage of the future_builtins
8256 module is:
8257 from future_builtins import hex, oct
8258
Eric Smith7ef40bf2008-02-20 23:34:22 +00008259- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8260 exponents for exponents with absolute value < 100. Follows C99
8261 standard. This is a change on Windows, which would use 3 digits.
8262 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8263 so that any alterations it does to the resulting string will be
8264 available in stringlib/formatter.h (for float.__format__).
8265
Eric Smith5a3c1352008-02-19 13:21:56 +00008266- Implemented PEP 3101, Advanced String Formatting. This adds a new
8267 builtin format(); a format() method for str and unicode; a
8268 __format__() method to object, str, unicode, int, long, float, and
8269 datetime; the class string.Formatter; and the C API
8270 PyObject_Format().
8271
Georg Brandl3ee81df2008-05-17 18:14:43 +00008272- Fixed several potential crashes, all caused by specially crafted
8273 __del__ methods exploiting objects in temporarily inconsistent
8274 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008275
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008276- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277 prevent a possible crash: an Abstract Base Class would try to access
8278 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Fixed repr() and str() of complex numbers with infinity or nan as
8281 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Clear all free lists during a gc.collect() of the highest generation
8284 in order to allow pymalloc to free more arenas. Python may give back
8285 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008286
Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Issue #2045: Fix an infinite recursion triggered when printing a
8288 subclass of collections.defaultdict, if its default_factory is set
8289 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008290
Christian Heimesf75dbef2008-02-08 00:11:31 +00008291- Fixed a minor memory leak in dictobject.c. The content of the free
8292 list was not freed on interpreter shutdown.
8293
Georg Brandl21e99f42010-03-07 15:23:59 +00008294- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008295 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008296
Georg Brandl3ee81df2008-05-17 18:14:43 +00008297- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8298 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008299 to compact the internal free lists of pre-allocted ints and floats.
8300
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8302 calls. Python expected the return type int but the fork familie
8303 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008304
Georg Brandl3ee81df2008-05-17 18:14:43 +00008305- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8306 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8309 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008310
Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8312 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008313
Georg Brandl3ee81df2008-05-17 18:14:43 +00008314- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8315 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008316
Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Patch #1473257: generator objects gain a gi_code attribute. This is
8318 the same object as the func_code attribute of the function that
8319 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008320
Georg Brandl3ee81df2008-05-17 18:14:43 +00008321- Issue #1920: "while 0" statements were completely removed by the
8322 compiler, even in the presence of an "else" clause, which is
8323 supposed to be run when the condition is false. Now the compiler
8324 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008325
Guido van Rossumeead05f2008-01-24 18:21:02 +00008326- A few crashers fixed: weakref_in_del.py (issue #1377858);
8327 loosing_dict_ref.py (issue #1303614, test67.py);
8328 borrowed_ref_[34].py (not in tracker).
8329
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008330- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008331 suppressed while an extension is loaded by calling SetErrorMode in
8332 dynload_win.c. The error is still reported properly.
8333
Georg Brandl3ee81df2008-05-17 18:14:43 +00008334- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008335 several extension methods and modules do not work without unicode
8336 support.
8337
Georg Brandl26543b12008-01-21 18:36:51 +00008338- Issue #1882: when compiling code from a string, encoding cookies in the
8339 second line of code were not always recognized correctly.
8340
Georg Brandl14404b62008-01-19 19:27:05 +00008341- Issue #1679: "0x" was taken as a valid integer literal.
8342
Georg Brandl6caad7d2008-01-26 14:19:22 +00008343- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008344 added.
8345
Christian Heimesc94e2b52008-01-14 04:13:37 +00008346- sys.float_info / PyFloat_GetInfo: The floating point information
8347 object was converted from a dict to a specialized structseq object.
8348
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Patch #1816: Added sys.flags structseq. It exposes the status of
8350 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008351
Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Objects/structseq.c: Implemented new structseq representation. The
8353 patch makes structseqs (e.g. the return value of os.stat) more
8354 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008355
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356- Patch #1700288: added a type attribute cache that caches method
8357 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008358
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008359- Bug #1776: __import__() no longer accepts filenames on any platform.
8360 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008361

8363
Georg Brandl3ee81df2008-05-17 18:14:43 +00008364- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8365 envvar and sys.dont_write_bytecode attribute. All these can be set
8366 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008367
Georg Brandl3ee81df2008-05-17 18:14:43 +00008368- Improve some exception messages when Windows fails to load an
8369 extension module. Now we get for example '%1 is not a valid Win32
8370 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008371
Georg Brandl3ee81df2008-05-17 18:14:43 +00008372- Bug #1481296: Fixed long(float('nan')) != 0L.

8375 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008376
Christian Heimes0a8143f2007-12-18 23:22:54 +00008377- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008378 and INF. float("nan"), float("inf") and float("-inf") now work on
8379 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008380
Georg Brandl3ee81df2008-05-17 18:14:43 +00008381- Compiler now generates simpler and faster code for dictionary
8382 literals. The oparg for BUILD_MAP now indicates an estimated
8383 dictionary size. There is a new opcode, STORE_MAP, for adding
8384 entries to the dictionary.

8416 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008417
Georg Brandl3ee81df2008-05-17 18:14:43 +00008418- Issue #1265: Fix a problem with sys.settrace, if the tracing
8419 function uses a generator expression when at the same time the
8420 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008421
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008422- sets and frozensets now have an isdisjoint() method.
8423
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008424- optimize the performance of builtin.sum().

8427
Georg Brandl21e99f42010-03-07 15:23:59 +00008428- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008429 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8430 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008431
Georg Brandl3ee81df2008-05-17 18:14:43 +00008432- Issue #1686386: Tuple's tp_repr did not take into account the
8433 possibility of having a self-referential tuple, which is possible
8434 from C code. Nor did object's tp_str consider that a type's tp_str
8435 could do something that could lead to an inifinite recursion.
8436 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8437 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008438
Georg Brandl3ee81df2008-05-17 18:14:43 +00008439- Issue #1164: It was possible to trigger deadlock when using the
8440 'print' statement to write to a file since the GIL was not released
8441 as needed. Now PyObject_Print() does the right thing along with
8442 various tp_print implementations of the built-in types and those in
8443 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008445- Issue #1147: Exceptions were directly allowing string exceptions in
8446 their throw() method even though string exceptions no longer
8447 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00008452- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008453 PyObject_Call() never calling back out to Python code to trigger
8454 recursion depth updates/checks. Required the creation of a static
8455 RuntimeError instance in case normalizing an exception put the
8456 recursion check value past its limit. Fixes crashers
8457 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008472- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008473 __*__ attributes. (Some already existed, e.g., __doc__ and
8474 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008475
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008476- Add -3 option to the interpreter to warn about features that are

8480 calls.
8481
Collin Winter62903052007-05-18 23:11:24 +00008482- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008483 "except E as target:". This is to provide forwards compatibility
8484 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008485
Brett Cannon229cee22007-05-05 01:34:02 +00008486- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008491- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008492 setting a plain string, ie don't expand to single letter identifiers.
8493
Raymond Hettinger13936692007-04-11 18:40:58 +00008494- Request #1191699: Slices can now be pickled.
8495
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008496- Request #1193128: str.translate() now allows a None argument for
8497 translations that only remove characters without re-mapping the
8498 remaining characters.
8499
Georg Brandl5cb76c12007-03-21 09:00:39 +00008500- Patch #1682205: a TypeError while unpacking an iterable is no longer

8502
Neal Norwitzaa754b72007-03-21 06:39:48 +00008503- Remove unused file Python/fmod.c.
8504
Guido van Rossum143b5642007-03-23 04:58:42 +00008505- Bug #1683368: The object.__init__() and object.__new__() methods are
8506 now stricter in rejecting excess arguments. The only time when
8507 either allows excess arguments is when it is not overridden and the
8508 other one is. For backwards compatibility, when both are
8509 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008510 warning later). Also, type.__init__() insists on the same signature
8511 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008512
Georg Brandl3ee81df2008-05-17 18:14:43 +00008513- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8514 object to complex using its __complex__() method before falling back
8515 to the __float__() method. Therefore, the functions in the cmath
8516 module now can operate on objects that define a __complex__()
8517 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008535- Bug #1678647: write a newline after printing an exception in any
8536 case, even when converting the value to a string failed.
8537
Georg Brandl871f1bc2007-03-12 13:17:36 +00008538- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008539 its argument, if it exists. If not, it will work like before. This
8540 allows customizing the output of dir() in the presence of a
8541 __getattr__().

8550 parthensized forms. This means complex(repr(x)) now works instead of
8551 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008552
Georg Brandlaa2321b2007-03-07 00:40:28 +00008553- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008554 makes the filenames the warning module prints much more sensible
8555 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008568- Patch #1674228: when assigning a slice (old-style), check for the
8569 sq_ass_slice instead of the sq_slice slot.
8570
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571- When printing an unraisable error, don't print exceptions. before

9181 Python would crash instead of raising an error.
9182

9198 accepted in TestSuite.addTest(). This should cause no
9199 incompatibility since it never made sense with ordinary subclasses
9200 -- the failure just occurred later, with a more cumbersome
9201 exception.

9479 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009480
Georg Brandl3ee81df2008-05-17 18:14:43 +00009481- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009482 that the SMTP.starttls() caller no longer needs to call ehlo()
9483 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009484 does not claim to support starttls. Adds the
9485 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9566 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9567 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009584 time so that opening a database previously created with the DB_DUP
9585 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9586 opens. Specifically: dictionary assignment to a DB object will
9587 replace all values for a given key when the database allows
9588 duplicate values. DB users should use DB.put(k, v) when they want
9589 to store duplicates; not DB[k] = v.

9596 characters with ASCII value less than 32. Also, it correctly quotes
9597 dots only if they occur on a single line, as opposed to the previous
9598 behavior of quoting dots if they are the second character of any
9599 line.

9927-----
9928
Georg Brandl3ee81df2008-05-17 18:14:43 +00009929- Unified naming convention for free lists and their limits. All free
9930 lists in Object/ are named ``free_list``, the counter ``numfree``
9931 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9932 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009933
Georg Brandl3ee81df2008-05-17 18:14:43 +00009934- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9935 to ``PyTuple_SetItem``, it can be used to populate a brand new
9936 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009937
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009938- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009940- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9941 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9942 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009943
9944- Patch #1720595: add T_BOOL to the range of structmember types.
9945
9946- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9947 ``PyFloat_GetInfo()`` to the float API.
9948
Georg Brandl3ee81df2008-05-17 18:14:43 +00009949- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9950 of w# format code incorrectly truncated the length to an int, even
9951 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9952 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009953
Georg Brandl3ee81df2008-05-17 18:14:43 +00009954- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9955 Py_TYPE and Py_REFCNT.

9962 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009963
9964- Patch #1733960: Allow T_LONGLONG to accept ints.

9972- Fix some leftovers from the conversion from int to Py_ssize_t
9973 (relevant to strings and sequences of more than 2**31 items).
9974
9975- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9976 outside of pystate.c and should not be necessary.
9977
Georg Brandl3ee81df2008-05-17 18:14:43 +00009978- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9979 absolute imports. In earlier versions they might have used relative
9980 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009981
Georg Brandl3ee81df2008-05-17 18:14:43 +00009982- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9983 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009984
Georg Brandl3ee81df2008-05-17 18:14:43 +00009985- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009991- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9992 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9993 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9994 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009995
Georg Brandl3ee81df2008-05-17 18:14:43 +00009996- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010008- Removed the macfs module. It had been deprecated since Python 2.5.
10009 This lead to the deprecation of macostools.touched() as it relied
10010 solely on macfs and was a no-op under OS X.
