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.

1192
Mark Dickinsondbbed042011-09-19 16:38:08 +01001193- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1194 int.__pow__. These overflow checks were causing int.__pow__ to produce
1195 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001196 compiler optimizing the check away. Also fix similar overflow checks
1197 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1198 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001209- Issue #12149: Update the method cache after a type's dictionnary gets
1210 cleared by the garbage collector. This fixes a segfault when an instance
1211 and its type get caught in a reference cycle, and the instance's
1212 deallocator calls one of the methods on the type (e.g. when subclassing
1213 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01001266- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001267 has left two versions of customize_compiler, the original in
1268 distutils.sysconfig and another copy in distutils.ccompiler, with some
1269 parts of distutils calling one and others using the other.
1270 Complete the revert back to only having one in distutils.sysconfig as
1271 is the case in 3.x.
1272
Ned Deily0d0ea482012-02-10 12:59:06 +01001273- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1274 Distutils-based packages with C extension modules may fail because
1275 Apple has removed gcc-4.2, the version used to build python.org
1276 64-bit/32-bit Pythons. If the user does not explicitly override
1277 the default C compiler by setting the CC environment variable,
1278 Distutils will now attempt to compile extension modules with clang
1279 if gcc-4.2 is required but not found. Also as a convenience, if
1280 the user does explicitly set CC, substitute its value as the default
1281 compiler in the Distutils LDSHARED configuration variable for OS X.
1282 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1283 SDK, neither of which are available in Xcode 4. This change does not
1284 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001557- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1558 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1559 interpreter process. This could cause failures in non-Distutils subprocesses
1560 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001561 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001562 deployment target only in the environment of each build subprocess. It is
1563 still possible to globally override the default by setting
1564 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1565 greater or equal to the default value, the value with which the interpreter
1566 was built.

1595 updating the check interval, so if the user decreases the check interval,
1596 the ticker doesn't have to wind down to zero from the old starting point
1597 before the new interval takes effect. And if the user increases the
1598 interval, it makes sure the new limit takes effect right away rather have an
1599 early task switch before recognizing the new interval.

2551 This prevents user-created self-referencing ordered dictionaries from
2552 becoming permanently uncollectable GC garbage. The downside is that
2553 removing __del__ means that the internal doubly-linked list has to wait for
2554 GC collection rather than freeing memory immediately when the refcnt drops
2555 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003014- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3015 start byte and the continuation byte(s) are now considered invalid, instead
3016 of the number of bytes specified by the start byte.
3017 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3018 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3019 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003028- Issue #8748: Fix two issues with comparisons between complex and integer
3029 objects. (1) The comparison could incorrectly return True in some cases
3030 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3031 (2) The comparison raised an OverflowError for large integers, leading
3032 to unpredictable exceptions when combining integers and complex objects
3033 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003035- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003172- Issue #1533: Fix inconsistency in range function argument processing: any
3173 non-float non-integer argument is now converted to an integer (if possible)
3174 using its __int__ method. Previously, only small arguments were treated this
3175 way; larger arguments (those whose __int__ was outside the range of a C long)
3176 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003405- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003406 on 64-bit machines. The shift count for either left or right shift is
3407 permitted to be up to sys.maxsize.
3408
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003409- Ensure that tokenization of identifiers is not affected by locale.
3410
Georg Brandlfee0f442010-05-22 21:26:21 +00003411- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003412
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003413- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3414
Georg Brandlfee0f442010-05-22 21:26:21 +00003415- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3416 with a non-empty format string. This is an effort to future-proof user
3417 code. If a derived class does not currently implement __format__ but later
3418 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003419 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003420 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003421
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003422- Issue #8268: Old-style classes (not just instances) now support weak
3423 references.
3424
Georg Brandlfee0f442010-05-22 21:26:21 +00003425- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3426 is set.

Victor Stinner66644262010-03-10 22:30:19 +00003435- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003436 (SIGINT). If an error occurs while importing the site module, the error is
3437 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003438 module.

3452
Georg Brandlfee0f442010-05-22 21:26:21 +00003453- Issue #8257: The Decimal construct now accepts a float instance directly,
3454 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003455
3456 >>> Decimal(1.1)
3457 Decimal('1.100000000000000088817841970012523233890533447265625')
3458
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003459- collections.Counter() now supports a subtract() method.
3460
Georg Brandlfee0f442010-05-22 21:26:21 +00003461- The functools module now has a total_ordering() class decorator to simplify
3462 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003464- The functools module also adds cmp_to_key() as a tool to transition old-style
3465 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003466
Georg Brandlfee0f442010-05-22 21:26:21 +00003467- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3468 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003469
Georg Brandlfee0f442010-05-22 21:26:21 +00003470- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3471 InvalidOperation instead of returning False. (Comparisons involving a quiet
3472 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3473 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003474
Georg Brandlfee0f442010-05-22 21:26:21 +00003475- Issue #2531: Comparison operations between floats and Decimal instances now
3476 return a result based on the numeric values of the operands; previously they
3477 returned an arbitrary result based on the relative ordering of id(float) and
3478 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003479
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003480- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003481 argument `-` which tells it to read files to compile from stdin. Each line is
3482 read on demand and the named file is compiled immediately. (Original patch by
3483 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003484
Georg Brandlfee0f442010-05-22 21:26:21 +00003485- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003488- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3489 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003490 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003491
Georg Brandlfee0f442010-05-22 21:26:21 +00003492- Comparisons using one of <, <=, >, >= between a complex instance and a
3493 Fractions instance now raise TypeError instead of returning True/False. This
3494 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3495 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003496

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003509
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003510- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3511 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003551 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3552 log file to compute the next rollover time. If the log file does not exist,
3553 the current time is used as the basis for the computation.

3564 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3565 This is a behavior change, so email's minor version number is now bumped, to

3600 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3601 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003602 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3603 inconsistent: __int__ was used for some integer codes but not for others, and
3604 the set of integer codes for which it was used differed between native packing
3605 and standard packing.)

Mark Dickinson8efef5c2010-01-12 22:23:56 +00003868
Georg Brandlba83f822010-03-14 09:50:54 +00003869 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
3870 strings,
3871 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3872 numeric strings corresponding to subnormal values,
3873 (3) a memory leak for some values large enough to cause overflow, and
3874 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00003913 file position when calling `truncate()`. It would previously change the file
3914 position to the given argument, which goes against the tradition of

3918 class used to represent files stored inside an archive. The new
3919 implementation is significantly faster and can be wrapped in a

3921 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4009Core and Builtins
4010-----------------
4011
Georg Brandlba83f822010-03-14 09:50:54 +00004012- The ``__complex__()`` method is now looked up on the class of instances to
4013 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004015- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4016 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4017
Mark Dickinson1b34d252010-01-01 17:27:30 +00004018- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004019 DeprecationWarning when passed a float argument where an integer was expected.
4020 These functions and methods now raise TypeError instead. The majority of the
4021 effects of this change are in the extension modules, but some core functions
4022 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4023 and many unicode/str methods.

4034 used to drop the time part of the result.
4035
Georg Brandlba83f822010-03-14 09:50:54 +00004036- Issue #1811: Improve accuracy and cross-platform consistency for true division
4037 of integers: the result of a/b is now correctly rounded for ints a and b (at
4038 least on IEEE 754 platforms), and in particular does not depend on the
4039 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004040
Georg Brandlba83f822010-03-14 09:50:54 +00004041- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4042 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4043 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004046 executables on OSX.
4047
Georg Brandlba83f822010-03-14 09:50:54 +00004048 These executables now work properly with the arch(1) command: ``arch -ppc
4049 python`` will start a universal binary version of python in PPC mode (unlike
4050 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004206- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4207 decimal string that's guaranteed to round back to x under correct rounding
4208 (with round-half-to-even rounding mode). Previously it gave a string based on
4209 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4210 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4211 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004212
Georg Brandlba83f822010-03-14 09:50:54 +00004213- Issue #7117: On almost all platforms: float-to-string and string-to-float
4214 conversions within Python are now correctly rounded. Places these conversions
4215 occur include: str for floats and complex numbers; the float and complex
4216 constructors; old-style and new-style numeric formatting; serialization and
4217 deserialization of floats and complex numbers using marshal, pickle and json;
4218 parsing of float and imaginary literals in Python code; Decimal-to-float
4219 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004220
Georg Brandlba83f822010-03-14 09:50:54 +00004221 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4222 providing correctly-rounded strtod and dtoa C functions. This code is
4223 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4224 the C compiler. There may be a small number of platforms on which correct
4225 operation of this code cannot be guaranteed, so the code is not used: notably,
4226 this applies to platforms where the C double format is not IEEE 754 binary64,
4227 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4228 and Python's configure script is unable to determine how to change the FPU
4229 precision. On these platforms conversions use the platform strtod and dtoa,
4230 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004232- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4233 uses the correctly-rounded string <-> float conversions described above (when
4234 available), and so produces correctly rounded results that will display nicely
4235 under the float repr. There are two related small changes: (1) round now
4236 accepts any class with an ``__index__()`` method for its second argument (but
4237 no longer accepts floats for the second argument), and (2) an excessively
4238 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4239 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004382 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4383 (2) parsing of strings representing infinities and nans was locale aware; and
4384 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004386- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4387 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4388 but with at least one decimal point and with a default precision
4389 of 12. Previously, the behavior the same but with a default precision of 6.
4390 This more closely matches ``str()``, and reduces surprises when adding
4391 alignment flags to the empty presentation type. This also affects the new
4392 complex.__format__ in the same way.
4393
4394- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004575- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4576 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4577 instances. On a typical machine this saves 3 bytes of memory (on average) per
4578 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004580- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

4589
Georg Brandlba83f822010-03-14 09:50:54 +00004590- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4591 file objects with closefd=False. The file descriptor is still kept open but
4592 the file object behaves like a closed file. The ``FileIO`` object also got a
4593 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00004616- On windows, ``os.chdir()`` given unicode was not working if

4618 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00004621- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4622 element is temporarily replaced with an equivalent frozenset. But the
4623 eventual KeyError would always report the empty ``frozenset()`` as the missing
4624 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004644- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4645 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4646 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4647 of using the replace error handler in PyUnicode_DecodeUTF8().
4648
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004649- Issue #3739: The unicode-internal encoder now reports the number of characters

4651
Georg Brandlba83f822010-03-14 09:50:54 +00004652- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4653 allocator will be automatically disabled when running under Valgrind. This
4654 gives improved memory leak detection when running under Valgrind, while taking
4655 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006020- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6021
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006022- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6023 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6024 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6025 ``printf`` function, whereas PyString_FromFormat has an independent
6026 implementation and uses "%zd" on all platforms for size_t values.
6027 This makes a difference on win64, where ``printf`` needs "%Id" to display
6028 64bit values.
6029
Benjamin Peterson97179b02008-09-09 20:55:01 +00006030- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6034 object; previously an int would be returned for small values. the __long__
6035 method is allowed to return either an int or a long, but the behaviour of
6036 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006038- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006044 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006045 was correctly parsed but parsing of subsequent arguments failed.
6046
Vinay Sajip35e3b032008-09-01 14:33:59 +00006047- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006048 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6049 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6050 when given a tuple of classes as second argument, were looking up
6051 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6052 type object.
6053
Neal Norwitz18aa3882008-08-24 05:04:52 +00006054- Fix crashes on memory allocation failure found with failmalloc.

6197-----------------
6198
Guido van Rossumf8402962008-08-20 15:01:50 +00006199- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6200 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6201 extensions do not automatically benefit from the class attribute
6202 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6203 to their tp_flags field if they care. This is a backwards
6204 compatibility feature; in 3.0, all types will use the cache by
6205 default.
6206
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006207- Keyword arguments can now follow starred arguments. (``f(a, *args,
6208 keyword=23)`` is now valid syntax.)
6209
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006210- ctypes function pointers that are COM methods have a boolean True
6211 value again.
6212
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006213- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6214 by denying s# to parse objects that have a releasebuffer procedure,

Mark Dickinsonb6467572008-08-04 21:30:09 +00006220- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6221 ValueError consistently across platforms.
6222
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006223- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6224 (64bit Unix, for example), unichr() would truncate its argument and return
6225 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6226
Neal Norwitze7d8be82008-07-31 17:17:14 +00006227- Apply security patches from Apple.
6228
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006229- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006235- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6236 the python debugger steps into a class statement: the free variables (local
6237 variables defined in an outer scope) would be deleted from the outer scope.
6238
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006239- Issue #2620: Overflow checking when allocating or reallocating memory
6240 was not always being done properly in some python types and extension
6241 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6242 all been updated to perform better checks and places in the code that
6243 would previously leak memory on the error path when such an allocation
6244 failed have been fixed.

6250
Benjamin Petersone977ad42008-08-20 01:42:01 +00006251- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6252 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6253
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006254- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6255 version reported by these tools does not necessarily follow the python
6256 version numbering scheme, so the module is less strict when parsing it.
6257
Nick Coghlanf70385a2008-08-18 12:42:46 +00006258- Issue #2235: Added Py3k warnings for types which will become unhashable
6259 under the stricter __hash__ inheritance rules in 3.0. Several types
6260 which did not meet the rules for hash invariants and were already
6261 unhashable in 3.0 have now been explicitly flagged as unhashable in
6262 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6263 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6264
Brett Cannon88f801d2008-08-18 00:46:22 +00006265- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6266 imported into the module but exposed as part of the module's API.
6267

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006274- Issue #3575: Incremental decoder's decode function now takes bytearray
6275 by using 's*' instead of 't#'.
6276
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006277- Issue #2222: Fixed reference leak when occurred os.rename()

6287 after a 302 response in the case of not going through a proxy.
6288
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006289- Issue #2676: in the email package, content-type parsing was hanging on
6290 pathological input because of quadratic or exponential behaviour of a
6291 regular expression.
6292
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006293- Issue #3476: binary buffered reading through the new "io" library is now
6294 thread-safe.
6295
Brett Cannonbf3157b2008-08-14 05:00:03 +00006296- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6297 since mimetools itself is deprecated. Because modules are cached, all
6298 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6299
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006300- Issue #3134: shutil referenced undefined WindowsError symbol.

6303 menu entries were not deleted.
6304
Brett Cannon83e81842008-08-09 23:30:55 +00006305- Copied the implementation of reduce() to _functools.reduce() to have a

6307
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006308- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6309 a MemoryError rather than silently stop the iteration.
6310
Guido van Rossum59ce9012008-08-09 14:55:34 +00006311- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6312 to _sre.compile() will now be rejected. This should not affect anybody
6313 since the re.compile() function never generates invalid re-bytecode.
6314
Skip Montanaroa032bf42008-08-08 22:52:51 +00006315- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6316 upon first access it can be automatically initialized from the csv file if
6317 it wasn't initialized during instantiation.
6318
Brett Cannon3aa2a492008-08-06 22:28:09 +00006319- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6320 the reload() built-in has been removed.
6321
Brett Cannon7e30b672008-08-04 21:52:25 +00006322- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006323 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6331 raised an AttributeError.
6332
Benjamin Peterson01a24322008-07-28 23:35:27 +00006333- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006334 asking for a specific length. This problem only affected files opened
6335 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006336

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006360- Issue #3394: zipfile.writestr sets external attributes when passed a
6361 file name rather than a ZipInfo instance, so files are extracted with
6362 mode 0600 rather than 000 under Unix.
6363
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006364- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6365 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006376- Issue #2235: the C API function PyObject_HashNotImplemented and its
6377 interaction with the tp_hash slot (added in 2.6b2) are now documented
6378
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006379- Issue #643841: The language reference now provides more detailed
6380 coverage of the lookup process for special methods. The disclaimers
6381 regarding lack of coverage of new-style classes have also been
6382 removed, since the coverage is now fairly reasonable.

6386================================
6387
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006388*Release date: 17-Jul-2008*
6389
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006390Core and Builtins
6391-----------------
6392
Georg Brandl3e483f62008-07-16 22:57:41 +00006393- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6394 its methods now allow for items objects that can be converted to
6395 an integer using operator.index().
6396
Mark Dickinson64b7e502008-07-16 09:40:03 +00006397- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6398 produced a ValueError instead of giving the correct float.
6399
Eric Smitha5fa5a22008-07-16 00:11:49 +00006400- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6401 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6402
Mark Dickinson7103aa42008-07-15 19:08:33 +00006403- Issue #3008: the float type has a new instance method 'float.hex'
6404 and a new class method 'float.fromhex' to convert floating-point
6405 numbers to and from hexadecimal strings, respectively.
6406
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006407- Issue #2235: __hash__ is once again inherited by default. To allow
6408 collections.Hashable to remain meaningful in the presence of the
6409 default hash implementation (object.__hash__), it is now possible
6410 to explicit block inheritance of hash by setting __hash__=None at
6411 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6412 level.
6413
Nick Coghlanb028f502008-07-13 14:52:36 +00006414- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6415 the parent module cannot be found while performing an absolute import.
6416 This means that an incorrectly defined __package__ attribute will
6417 now only prevent relative imports in that module rather than causing
6418 all imports from that module to fail.
6419
Nick Coghlan14ff9942008-07-08 14:21:42 +00006420- Issue #2517: Allow unicode messages in Exceptions again by correctly
6421 bypassing the instance dictionary when looking up __unicode__ on
6422 new-style classes.
6423
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006424- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6425 set to a custom object whose write() method happens to install
6426 another file in sys.stdout.
6427
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006428- Issue #3088: Corrected a race condition in classes derived from
6429 threading.local: the first member set by a thread could be saved in
6430 another thread's dictionary.
6431
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006432- Issue #3004: Minor change to slice.indices(): the start and stop
6433 arguments are now treated identically, making the behaviour easier
6434 to describe and understand. For example, slice(None, -10,
6435 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6436 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6437 10, -1).
6438
Georg Brandl278fc502008-07-19 12:46:12 +00006439- Issue #3219: Calling a function with repeated keyword arguments,
6440 f(a=2, a=23), would not cause a syntax error. This was a regression
6441 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006442
Georg Brandl278fc502008-07-19 12:46:12 +00006443- Issue #2862: Make int and float freelist management consistent with
6444 other freelists. Changes their CompactFreeList apis into
6445 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006446

6448-------
6449
Thomas Heller57adf222008-08-14 19:10:48 +00006450- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6451 api functions without holding the GIL, which could lead to a fatal
6452 error when they failed.
6453
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006454- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006462- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6463 ForkingPickler.register() to resolve conflict with ctypes.
6464
Vinay Sajip51e65192008-07-18 09:01:10 +00006465- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006466
Thomas Heller880f5292008-07-15 19:39:38 +00006467- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6468 a valid dlerror() message.
6469
Thomas Heller2bad6572008-07-15 17:19:50 +00006470- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6471 incomplete structure was created.
6472
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006473- Issue #3339: dummy_thread.acquire() should not return None.
6474
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006475- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6476
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006477- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006478
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006479- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6480 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006481 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006482 content-length. The problem had been corrected in the 2.4 branch, but never
6483 merged into trunk.
6484
Georg Brandle78fbcc2008-07-05 10:13:36 +00006485- Issue #2663: add filtering capability to shutil.copytree().

6491- Issue #1746: Correct handling of zipfile archive comments (previously
6492 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006493 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006494
Vinay Sajip51e65192008-07-18 09:01:10 +00006495- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006496 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006497
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006498- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6499 handling is now the same as that of other special attributes like __name__).
6500
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006501- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6502 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006891 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006892
6893 This is controlled by the configure argument ``--with-universal-archs``:
6894
6895 - ``--with-universal-archs=all``: install 4-way universal
6896
6897 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6898
6899 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6900
6901 This option should be used in combination with ``--enable-universalsdk=``.
6902
6903 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006953- Issue #1631171: Re-implement the 'warnings' module in C (the
6954 original Python code has been kept as backup). This will allow for
6955 using the 'warning's machinery in such places as the parser where
6956 use of pure Python code is not possible. Both the ``showarning()``
6957 and ``formatwarning()`` gain an optional 'line' argument which is
6958 not called by default for backwards-compatibility reasons. Setting
6959 ``warnings.showwarning()`` to an implementation that lacks support
6960 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007023- Issue #2550: The approach used by client/server code for obtaining
7024 ports to listen on in network-oriented tests has been refined in an
7025 effort to facilitate running multiple instances of the entire
7026 regression test suite in parallel without issue.
7027 test_support.bind_port() has been fixed such that it will always
7028 return a unique port -- which wasn't always the case with the
7029 previous implementation, especially if socket options had been set
7030 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7031 new implementation of bind_port() will actually raise an exception
7032 if it is passed an AF_INET/SOCK_STREAM socket with either the
7033 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7034 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7035 the socket it's been passed. This currently only applies to
7036 Windows. This option prevents any other sockets from binding to the
7037 host/port we've bound to, thus removing the possibility of the
7038 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7039 when a second SOCK_STREAM socket binds and accepts to a host/port
7040 that's already been bound by another socket. The optional preferred
7041 port parameter to bind_port() has been removed. Under no
7042 circumstances should tests be hard coding ports!
7043
7044 test_support.find_unused_port() has also been introduced, which will
7045 pass a temporary socket object to bind_port() in order to obtain an
7046 unused port. The temporary socket object is then closed and
7047 deleted, and the port is returned. This method should only be used
7048 for obtaining an unused port in order to pass to an external program
7049 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7050 a parameter to a server-oriented class that doesn't give you direct
7051 access to the underlying socket used.
7052
7053 Finally, test_support.HOST has been introduced, which should be used
7054 for the host argument of any relevant socket calls (i.e. bind and
7055 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007056
7057 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007058 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7060 test_asynchat and test_socket_ssl.
7061
Georg Brandl3ee81df2008-05-17 18:14:43 +00007062 It is now possible for multiple instances of the regression test

7329Core and builtins
7330-----------------
7331
Fred Drakea8ee94b2008-03-01 02:45:07 +00007332- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007333 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007334
Georg Brandlad61bc82008-02-23 15:11:18 +00007335- Issue #2067: file.__exit__() now calls subclasses' close() method.
7336
7337- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007338
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007339- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007340 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007341
Eric Smitha73fbe72008-02-23 03:09:44 +00007342- Added the future_builtins module, which contains hex() and oct().
7343 These are the PEP 3127 version of these functions, designed to be
7344 compatible with the hex() and oct() builtins from Python 3.0. They
7345 differ slightly in their output formats from the existing, unchanged
7346 Python 2.6 builtins. The expected usage of the future_builtins
7347 module is:
7348 from future_builtins import hex, oct
7349
Eric Smith7ef40bf2008-02-20 23:34:22 +00007350- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7351 exponents for exponents with absolute value < 100. Follows C99
7352 standard. This is a change on Windows, which would use 3 digits.
7353 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7354 so that any alterations it does to the resulting string will be
7355 available in stringlib/formatter.h (for float.__format__).
7356
Eric Smith5a3c1352008-02-19 13:21:56 +00007357- Implemented PEP 3101, Advanced String Formatting. This adds a new
7358 builtin format(); a format() method for str and unicode; a
7359 __format__() method to object, str, unicode, int, long, float, and
7360 datetime; the class string.Formatter; and the C API
7361 PyObject_Format().
7362
Georg Brandl3ee81df2008-05-17 18:14:43 +00007363- Fixed several potential crashes, all caused by specially crafted
7364 __del__ methods exploiting objects in temporarily inconsistent
7365 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007366
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007367- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368 prevent a possible crash: an Abstract Base Class would try to access
7369 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007370
Georg Brandl3ee81df2008-05-17 18:14:43 +00007371- Fixed repr() and str() of complex numbers with infinity or nan as
7372 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007373
Georg Brandl3ee81df2008-05-17 18:14:43 +00007374- Clear all free lists during a gc.collect() of the highest generation
7375 in order to allow pymalloc to free more arenas. Python may give back
7376 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007377
Georg Brandl3ee81df2008-05-17 18:14:43 +00007378- Issue #2045: Fix an infinite recursion triggered when printing a
7379 subclass of collections.defaultdict, if its default_factory is set
7380 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007381
Christian Heimesf75dbef2008-02-08 00:11:31 +00007382- Fixed a minor memory leak in dictobject.c. The content of the free
7383 list was not freed on interpreter shutdown.
7384
Georg Brandl21e99f42010-03-07 15:23:59 +00007385- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007386 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007387
Georg Brandl3ee81df2008-05-17 18:14:43 +00007388- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7389 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007390 to compact the internal free lists of pre-allocted ints and floats.
7391
Georg Brandl3ee81df2008-05-17 18:14:43 +00007392- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7393 calls. Python expected the return type int but the fork familie
7394 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007395
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7397 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007398
Georg Brandl3ee81df2008-05-17 18:14:43 +00007399- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7400 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007401
Georg Brandl3ee81df2008-05-17 18:14:43 +00007402- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7403 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007404
Georg Brandl3ee81df2008-05-17 18:14:43 +00007405- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7406 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Patch #1473257: generator objects gain a gi_code attribute. This is
7409 the same object as the func_code attribute of the function that
7410 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007411
Georg Brandl3ee81df2008-05-17 18:14:43 +00007412- Issue #1920: "while 0" statements were completely removed by the
7413 compiler, even in the presence of an "else" clause, which is
7414 supposed to be run when the condition is false. Now the compiler
7415 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007416
Guido van Rossumeead05f2008-01-24 18:21:02 +00007417- A few crashers fixed: weakref_in_del.py (issue #1377858);
7418 loosing_dict_ref.py (issue #1303614, test67.py);
7419 borrowed_ref_[34].py (not in tracker).
7420
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007421- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007422 suppressed while an extension is loaded by calling SetErrorMode in
7423 dynload_win.c. The error is still reported properly.
7424
Georg Brandl3ee81df2008-05-17 18:14:43 +00007425- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007426 several extension methods and modules do not work without unicode
7427 support.
7428
Georg Brandl26543b12008-01-21 18:36:51 +00007429- Issue #1882: when compiling code from a string, encoding cookies in the
7430 second line of code were not always recognized correctly.
7431
Georg Brandl14404b62008-01-19 19:27:05 +00007432- Issue #1679: "0x" was taken as a valid integer literal.
7433
Georg Brandl6caad7d2008-01-26 14:19:22 +00007434- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007435 added.
7436
Christian Heimesc94e2b52008-01-14 04:13:37 +00007437- sys.float_info / PyFloat_GetInfo: The floating point information
7438 object was converted from a dict to a specialized structseq object.
7439
Georg Brandl3ee81df2008-05-17 18:14:43 +00007440- Patch #1816: Added sys.flags structseq. It exposes the status of
7441 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007442
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443- Objects/structseq.c: Implemented new structseq representation. The
7444 patch makes structseqs (e.g. the return value of os.stat) more
7445 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007446
Georg Brandl3ee81df2008-05-17 18:14:43 +00007447- Patch #1700288: added a type attribute cache that caches method
7448 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007449
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007450- Bug #1776: __import__() no longer accepts filenames on any platform.
7451 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007452
Georg Brandlaed6c662008-01-07 17:25:53 +00007453- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7454
Georg Brandl3ee81df2008-05-17 18:14:43 +00007455- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7456 envvar and sys.dont_write_bytecode attribute. All these can be set
7457 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Improve some exception messages when Windows fails to load an
7460 extension module. Now we get for example '%1 is not a valid Win32
7461 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007462
Georg Brandl3ee81df2008-05-17 18:14:43 +00007463- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007465- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7466 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007467
Christian Heimes0a8143f2007-12-18 23:22:54 +00007468- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007469 and INF. float("nan"), float("inf") and float("-inf") now work on
7470 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007471
Georg Brandl3ee81df2008-05-17 18:14:43 +00007472- Compiler now generates simpler and faster code for dictionary
7473 literals. The oparg for BUILD_MAP now indicates an estimated
7474 dictionary size. There is a new opcode, STORE_MAP, for adding
7475 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007476
Georg Brandl3ee81df2008-05-17 18:14:43 +00007477- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007479- Issue #1620: New property decorator syntax was modifying the
7480 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007481
Georg Brandl3ee81df2008-05-17 18:14:43 +00007482- Issue #1538: Avoid copying string in split/rsplit if the split char
7483 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007484
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007485- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007486 SystemError.
7487
Nick Coghlanef01d822007-12-03 12:55:17 +00007488- PEP 366: Allow explicit relative imports when executing modules
7489 inside packages with the -m switch via a new module level
7490 __package__ attribute.
7491
Georg Brandl3ee81df2008-05-17 18:14:43 +00007492- Issue #1402: Fix a crash on exit, when another thread is still
7493 running, and if the deallocation of its frames somehow calls the
7494 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007495

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007499 attribute of an empty cell object.
7500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501- Issue #1460: The utf-7 incremental decoder did not accept truncated
7502 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007503
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504- Patch #1739468: Directories and zipfiles containing a __main__.py
7505 file can now be directly executed by passing their name to the
7506 interpreter. The directory/zipfile is automatically inserted as the
7507 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007508
Georg Brandl3ee81df2008-05-17 18:14:43 +00007509- Issue #1265: Fix a problem with sys.settrace, if the tracing
7510 function uses a generator expression when at the same time the
7511 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007512
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007513- sets and frozensets now have an isdisjoint() method.
7514
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007515- optimize the performance of builtin.sum().
7516
Neal Norwitz44f326e2007-10-05 05:29:17 +00007517- Fix warnings found by the new version of the Coverity checker.
7518
Georg Brandl21e99f42010-03-07 15:23:59 +00007519- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007520 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7521 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007522
Georg Brandl3ee81df2008-05-17 18:14:43 +00007523- Issue #1686386: Tuple's tp_repr did not take into account the
7524 possibility of having a self-referential tuple, which is possible
7525 from C code. Nor did object's tp_str consider that a type's tp_str
7526 could do something that could lead to an inifinite recursion.
7527 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7528 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007529
Georg Brandl3ee81df2008-05-17 18:14:43 +00007530- Issue #1164: It was possible to trigger deadlock when using the
7531 'print' statement to write to a file since the GIL was not released
7532 as needed. Now PyObject_Print() does the right thing along with
7533 various tp_print implementations of the built-in types and those in
7534 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007535
Georg Brandl3ee81df2008-05-17 18:14:43 +00007536- Issue #1147: Exceptions were directly allowing string exceptions in
7537 their throw() method even though string exceptions no longer
7538 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007539
Georg Brandl3ee81df2008-05-17 18:14:43 +00007540- Issue #1096: Prevent a segfault from getting the repr of a very
7541 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007542
Brett Cannon1e534b52007-09-07 04:18:30 +00007543- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007544 PyObject_Call() never calling back out to Python code to trigger
7545 recursion depth updates/checks. Required the creation of a static
7546 RuntimeError instance in case normalizing an exception put the
7547 recursion check value past its limit. Fixes crashers
7548 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007549
Georg Brandl3ee81df2008-05-17 18:14:43 +00007550- Patch #1031213: Decode source line in SyntaxErrors back to its

7554 with %G.
7555
Georg Brandl3ee81df2008-05-17 18:14:43 +00007556- Prevent expandtabs() on string and unicode objects from causing a
7557 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007558
Georg Brandl3ee81df2008-05-17 18:14:43 +00007559- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007567- Add -3 option to the interpreter to warn about features that are
7568 deprecated and will be changed/removed in Python 3.0.
7569
Georg Brandl2134e752007-05-21 20:34:16 +00007570- Patch #1686487: you can now pass any mapping after '**' in function
7571 calls.
7572
Collin Winter62903052007-05-18 23:11:24 +00007573- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007574 "except E as target:". This is to provide forwards compatibility
7575 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007576
Brett Cannon229cee22007-05-05 01:34:02 +00007577- Deprecate BaseException.message as per PEP 352.
7578
Georg Brandl3ee81df2008-05-17 18:14:43 +00007579- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007580 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007581
Vinay Sajip8549ce32007-05-06 17:53:37 +00007582- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007583 setting a plain string, ie don't expand to single letter identifiers.
7584
Raymond Hettinger13936692007-04-11 18:40:58 +00007585- Request #1191699: Slices can now be pickled.
7586
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007587- Request #1193128: str.translate() now allows a None argument for
7588 translations that only remove characters without re-mapping the
7589 remaining characters.
7590
Georg Brandl5cb76c12007-03-21 09:00:39 +00007591- Patch #1682205: a TypeError while unpacking an iterable is no longer
7592 masked by a generic one with the message "unpack non-sequence".
7593

7595
Guido van Rossum143b5642007-03-23 04:58:42 +00007596- Bug #1683368: The object.__init__() and object.__new__() methods are
7597 now stricter in rejecting excess arguments. The only time when
7598 either allows excess arguments is when it is not overridden and the
7599 other one is. For backwards compatibility, when both are
7600 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007601 warning later). Also, type.__init__() insists on the same signature
7602 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007603
Georg Brandl3ee81df2008-05-17 18:14:43 +00007604- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7605 object to complex using its __complex__() method before falling back
7606 to the __float__() method. Therefore, the functions in the cmath
7607 module now can operate on objects that define a __complex__()
7608 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007609
Georg Brandl3ee81df2008-05-17 18:14:43 +00007610- Patch #1623563: allow __class__ assignment for classes with
7611 __slots__. The old and the new class are still required to have the
7612 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007613

7625
Georg Brandl7b9c5552007-03-12 14:30:05 +00007626- Bug #1678647: write a newline after printing an exception in any
7627 case, even when converting the value to a string failed.
7628
Georg Brandl871f1bc2007-03-12 13:17:36 +00007629- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007630 its argument, if it exists. If not, it will work like before. This
7631 allows customizing the output of dir() in the presence of a
7632 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007633
Collin Winter276887b2007-03-12 16:11:39 +00007634- Patch #922167: Python no longer segfaults when faced with infinitely
7635 self-recursive reload() calls (as reported by bug #742342).
7636
Georg Brandl3ee81df2008-05-17 18:14:43 +00007637- Patch #1675981: remove unreachable code from ``type.__new__()``
7638 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007640- Patch #1491866: change the complex() constructor to allow
7641 parthensized forms. This means complex(repr(x)) now works instead of
7642 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007643
Georg Brandlaa2321b2007-03-07 00:40:28 +00007644- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007645 makes the filenames the warning module prints much more sensible
7646 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007647
Georg Brandl49aafc92007-03-07 00:34:46 +00007648- Variant of patch #697613: don't exit the interpreter on a SystemExit
7649 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650 variable is given, but break into the interactive interpreter just
7651 like on other exceptions or normal program exit.

7657 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00007658
Georg Brandl0fca97a2007-03-05 22:28:08 +00007659- Patch #1674228: when assigning a slice (old-style), check for the
7660 sq_ass_slice instead of the sq_slice slot.
7661
Georg Brandl3ee81df2008-05-17 18:14:43 +00007662- When printing an unraisable error, don't print exceptions. before
7663 the name. This duplicates the behavior whening normally printing
7664 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00007665
Georg Brandl3ee81df2008-05-17 18:14:43 +00007666- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00007672- Bug #1377858: Fix the segfaulting of the interpreter when an object
7673 created a weakref on itself during a __del__ call for new-style
7674 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00007675
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00007676- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

7715 embedded in the string to convert.
7716
Georg Brandl846f73a2006-10-08 07:11:54 +00007717- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007765 generator expressions (x for x, in ... ) works again. Fixing this
7766 problem required changing the .pyc magic number. This means that
7767 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008197 AttributeError instead of an IOError when the server's response
8198 didn't contain a valid HTTP status line.

8230
Georg Brandl92a6bae2007-03-13 17:43:32 +00008231- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

8289 TestCase and TestSuite subclasses (not instances) are no longer
8290 accepted in TestSuite.addTest(). This should cause no
8291 incompatibility since it never made sense with ordinary subclasses
8292 -- the failure just occurred later, with a more cumbersome
8293 exception.

8572 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008573
Georg Brandl3ee81df2008-05-17 18:14:43 +00008574- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8575 with RFC 3207 and forgets any knowledge obtained from the server not
8576 obtained from the TLS negotiation itself. Patch contributed by Bill
8577 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008578
Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008580 that the SMTP.starttls() caller no longer needs to call ehlo()
8581 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008582 does not claim to support starttls. Adds the
8583 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8664 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8665 silently miscode subclasses of those types. Now, it raises a
8666 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008667

Georg Brandl3ee81df2008-05-17 18:14:43 +00008682 time so that opening a database previously created with the DB_DUP
8683 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8684 opens. Specifically: dictionary assignment to a DB object will
8685 replace all values for a given key when the database allows
8686 duplicate values. DB users should use DB.put(k, v) when they want
8687 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008688

8694 characters with ASCII value less than 32. Also, it correctly quotes
8695 dots only if they occur on a single line, as opposed to the previous
8696 behavior of quoting dots if they are the second character of any
8697 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008698

Georg Brandl3ee81df2008-05-17 18:14:43 +00009033- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9034 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9035 PyLong_FromSsize_t public functions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009042- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9043 of w# format code incorrectly truncated the length to an int, even
9044 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9045 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009046
Georg Brandl3ee81df2008-05-17 18:14:43 +00009047- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9065- Fix some leftovers from the conversion from int to Py_ssize_t
9066 (relevant to strings and sequences of more than 2**31 items).
9067
9068- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9069 outside of pystate.c and should not be necessary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009075- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9076 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009077
Georg Brandl3ee81df2008-05-17 18:14:43 +00009078- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009085- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9086 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9087 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9088 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009103- Removed the macfs module. It had been deprecated since Python 2.5.
9104 This lead to the deprecation of macostools.touched() as it relied
9105 solely on macfs and was a no-op under OS X.
