Ned Deily18fae3f2013-01-31 01:24:55 -0800821- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
822 In particular, fix extension module build failures when trying to use
823 32-bit-only installer Pythons on systems with Xcode 4 (currently
824 OS X 10.8, 10.7, and optionally 10.6).
825 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
826 * Since Xcode 4 removes ppc support, extension module builds now
827 check for ppc compiler support and by default remove ppc and
828 ppc64 archs when they are not available.
829 * Extension module builds now revert to using system installed
830 headers and libs (/usr and /System/Library) if the SDK used
831 to build the interpreter is not installed or has moved.
832 * Try to avoid building extension modules with deprecated
833 and problematic Apple llvm-gcc compiler. If original compiler
834 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001191- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001192 has left two versions of customize_compiler, the original in
1193 distutils.sysconfig and another copy in distutils.ccompiler, with some
1194 parts of distutils calling one and others using the other.
1195 Complete the revert back to only having one in distutils.sysconfig as
1196 is the case in 3.x.
1197
Ned Deily0d0ea482012-02-10 12:59:06 +01001198- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1199 Distutils-based packages with C extension modules may fail because
1200 Apple has removed gcc-4.2, the version used to build python.org
1201 64-bit/32-bit Pythons. If the user does not explicitly override
1202 the default C compiler by setting the CC environment variable,
1203 Distutils will now attempt to compile extension modules with clang
1204 if gcc-4.2 is required but not found. Also as a convenience, if
1205 the user does explicitly set CC, substitute its value as the default
1206 compiler in the Distutils LDSHARED configuration variable for OS X.
1207 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1208 SDK, neither of which are available in Xcode 4. This change does not
1209 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001482- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1483 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1484 interpreter process. This could cause failures in non-Distutils subprocesses
1485 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001486 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001487 deployment target only in the environment of each build subprocess. It is
1488 still possible to globally override the default by setting
1489 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1490 greater or equal to the default value, the value with which the interpreter
1491 was built.

1521 the ticker doesn't have to wind down to zero from the old starting point
1522 before the new interval takes effect. And if the user increases the
1523 interval, it makes sure the new limit takes effect right away rather have an
1524 early task switch before recognizing the new interval.

2319
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002320- Issue #9869: Make long() and PyNumber_Long return something of type
2321 long for a class whose __long__ method returns a plain int. This
2322 fixes an interpreter crash when initializing an instance of a long
2323 subclass from an object whose __long__ method returns a plain int.

2328 thread-local storage key.
2329
Victor Stinnercaafd772010-09-08 10:51:01 +00002330- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2331 encoding and errors attributes instead of using utf-8 in strict mode, to get
2332 the same behaviour than the print statement.
2333
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002334- Issue #9737: Fix a crash when trying to delete a slice or an item from
2335 a memoryview object.

2348
2349 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2350 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2474
Raymond Hettinger20397532010-09-12 02:11:45 +00002475- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2476 This prevents user-created self-referencing ordered dictionaries from
2477 becoming permanently uncollectable GC garbage. The downside is that
2478 removing __del__ means that the internal doubly-linked list has to wait for
2479 GC collection rather than freeing memory immediately when the refcnt drops
2480 to zero.
2481

2485
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002486- Issue #9792: In case of connection failure, socket.create_connection()
2487 would swallow the exception and raise a new one, making it impossible
2488 to fetch the original errno, or to filter timeout errors. Now the
2489 original error is re-raised.

Antoine Pitrouf4f61712010-09-07 16:34:47 +00002491- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2500
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002501- Issue #808164: Fixed socket.close to avoid references to globals, to

2509 falling into recursion.
2510
R. David Murray7c4bf552010-08-25 01:45:57 +00002511- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2512 character years even if the message contains RFC822 two character years.
2513
Daniel Stutzbach91287322010-08-24 21:09:30 +00002514- Issue #8750: Fixed MutableSet's methods to correctly handle

2527
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002528- Issue #9617: Signals received during a low-level write operation aren't

2530
Benjamin Peterson52c36052010-08-21 03:03:22 +00002531- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2533
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002534- Issue #9626: the view methods for collections.OrderedDict() were returning

2540 without this marker will not be overwritten or removed.
2541
Antoine Pitroue1436d12010-08-12 15:25:51 +00002542- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

2544 case in Python 2.5 and earlier).
2545
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002546- Issue #9550: a BufferedReader could issue an additional read when the

2548 when the underlying raw IO channel was e.g. a socket. Report and original
2549 patch by Jason V. Miller.
2550
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002551- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002569- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2570 This is how it is supposed to work, wget and curl do the same. Previous
2571 behavior was wrong.

2580 does not contain a '-', instead of raising an error.
2581

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002939- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2940 start byte and the continuation byte(s) are now considered invalid, instead
2941 of the number of bytes specified by the start byte.
2942 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2943 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2944 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2945 Previous versions returned a single u'\ufffd'.

2949 arises from the "Overriding __eq__ blocks inheritance ..." warning
2950 when turned into an exception: in this case the exception simply
2951 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002953- Issue #8748: Fix two issues with comparisons between complex and integer
2954 objects. (1) The comparison could incorrectly return True in some cases
2955 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2956 (2) The comparison raised an OverflowError for large integers, leading
2957 to unpredictable exceptions when combining integers and complex objects
2958 in sets or dicts.
2959
Mark Dickinson81336372010-05-30 12:12:25 +00002960- Issue #5211: Implicit coercion for the complex type is now completely
2961 removed. (Coercion for arithmetic operations was already removed in 2.7
2962 alpha 4, but coercion for rich comparisons was accidentally left in.)
2963
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002964- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00003151- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3152 operation raises multiple signals and more than one of those signals is
3153 trapped, the specification determines the order in which the signals should be
3154 handled. In many cases this order wasn't being followed, leading to the wrong
3155 Python exception being raised.

3341 with a non-empty format string. This is an effort to future-proof user
3342 code. If a derived class does not currently implement __format__ but later
3343 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003344 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003345 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003378- Issue #8257: The Decimal construct now accepts a float instance directly,
3379 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003380
3381 >>> Decimal(1.1)
3382 Decimal('1.100000000000000088817841970012523233890533447265625')
3383
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003384- collections.Counter() now supports a subtract() method.
3385
Georg Brandlfee0f442010-05-22 21:26:21 +00003386- The functools module now has a total_ordering() class decorator to simplify
3387 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003389- The functools module also adds cmp_to_key() as a tool to transition old-style
3390 comparison functions to new-style key-functions.

Georg Brandlfee0f442010-05-22 21:26:21 +00003395- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3396 InvalidOperation instead of returning False. (Comparisons involving a quiet
3397 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3398 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003400- Issue #2531: Comparison operations between floats and Decimal instances now
3401 return a result based on the numeric values of the operands; previously they
3402 returned an arbitrary result based on the relative ordering of id(float) and
3403 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003405- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003406 argument `-` which tells it to read files to compile from stdin. Each line is
3407 read on demand and the named file is compiled immediately. (Original patch by
3408 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00003417- Comparisons using one of <, <=, >, >= between a complex instance and a
3418 Fractions instance now raise TypeError instead of returning True/False. This
3419 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3420 <=> complex, and complex <=> complex comparisons.

3520 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003524- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3525 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3526 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003527 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3528 inconsistent: __int__ was used for some integer codes but not for others, and
3529 the set of integer codes for which it was used differed between native packing
3530 and standard packing.)

3843 class used to represent files stored inside an archive. The new
3844 implementation is significantly faster and can be wrapped in a
3845 ``io.BufferedReader`` object for more speedups. It also solves an issue
3846 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3859 encoded string for them. This ensures that the upload and register commands
3860 send the correct values to PyPI without any error.

3942
Mark Dickinson1b34d252010-01-01 17:27:30 +00003943- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003944 DeprecationWarning when passed a float argument where an integer was expected.
3945 These functions and methods now raise TypeError instead. The majority of the
3946 effects of this change are in the extension modules, but some core functions
3947 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3948 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004113- Issue #3382: 'F' formatting for float and complex now convert the result to
4114 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4115 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004116
Georg Brandlba83f822010-03-14 09:50:54 +00004117- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4118 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004119
Georg Brandlba83f822010-03-14 09:50:54 +00004120- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4121 1e-100 used to raise OverflowError, but now gives the requested 120
4122 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004131- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4132 decimal string that's guaranteed to round back to x under correct rounding
4133 (with round-half-to-even rounding mode). Previously it gave a string based on
4134 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4135 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4136 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004137
Georg Brandlba83f822010-03-14 09:50:54 +00004138- Issue #7117: On almost all platforms: float-to-string and string-to-float
4139 conversions within Python are now correctly rounded. Places these conversions
4140 occur include: str for floats and complex numbers; the float and complex
4141 constructors; old-style and new-style numeric formatting; serialization and
4142 deserialization of floats and complex numbers using marshal, pickle and json;
4143 parsing of float and imaginary literals in Python code; Decimal-to-float
4144 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004145
Georg Brandlba83f822010-03-14 09:50:54 +00004146 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4147 providing correctly-rounded strtod and dtoa C functions. This code is
4148 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4149 the C compiler. There may be a small number of platforms on which correct
4150 operation of this code cannot be guaranteed, so the code is not used: notably,
4151 this applies to platforms where the C double format is not IEEE 754 binary64,
4152 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4153 and Python's configure script is unable to determine how to change the FPU
4154 precision. On these platforms conversions use the platform strtod and dtoa,
4155 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004157- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4158 uses the correctly-rounded string <-> float conversions described above (when
4159 available), and so produces correctly rounded results that will display nicely
4160 under the float repr. There are two related small changes: (1) round now
4161 accepts any class with an ``__index__()`` method for its second argument (but
4162 no longer accepts floats for the second argument), and (2) an excessively
4163 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4164 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004311- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4312 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4313 but with at least one decimal point and with a default precision
4314 of 12. Previously, the behavior the same but with a default precision of 6.
4315 This more closely matches ``str()``, and reduces surprises when adding
4316 alignment flags to the empty presentation type. This also affects the new
4317 complex.__format__ in the same way.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005945- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5946
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005947- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5948 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5949 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5950 ``printf`` function, whereas PyString_FromFormat has an independent
5951 implementation and uses "%zd" on all platforms for size_t values.
5952 This makes a difference on win64, where ``printf`` needs "%Id" to display
5953 64bit values.
5954
Benjamin Peterson97179b02008-09-09 20:55:01 +00005955- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5956 error.
5957
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005958- Issue #3777: long() applied to a float object now always return a long
5959 object; previously an int would be returned for small values. the __long__
5960 method is allowed to return either an int or a long, but the behaviour of
5961 float objects should not change to respect backward compatibility.
5962
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005963- Issue #3751: str.rpartition would perform a left-partition when called with
5964 a unicode argument.
5965
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005966- Issue #3683: Fix compilation when --without-threads is given.
5967
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005968- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005969 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005970 was correctly parsed but parsing of subsequent arguments failed.
5971
Vinay Sajip35e3b032008-09-01 14:33:59 +00005972- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005973 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5974 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5975 when given a tuple of classes as second argument, were looking up
5976 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5977 type object.
5978
Neal Norwitz18aa3882008-08-24 05:04:52 +00005979- Fix crashes on memory allocation failure found with failmalloc.
5980
5981- Fix memory leaks found with valgrind and update suppressions file.
5982
5983- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5984
5985- Fix problem using wrong name in decimal module reported by pychecker.
5986
Christian Heimes7d4c3172008-08-22 19:47:25 +00005987- Silenced another compiler warning about a used but not defined
5988 function 'stringlib_contains_obj'.
5989
Benjamin Peterson712ee922008-08-24 18:10:20 +00005990- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5991 ``__delslice__``.
5992
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005993- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5994 library targets in the Makefile.
5995
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005996- Issue #1204: The configure script now tests for additional libraries
5997 that may be required when linking against readline. This fixes issues
5998 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006048 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6049 for catch_warnings() also led to an improvement in the raising of a
6050 DeprecationWarning related to warnings.warn_explicit().
6051
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006052- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006116What's New in Python 2.6 beta 3?
6117================================
6118
Barry Warsaw07a4a382008-08-21 01:15:08 +00006119*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006120
6121Core and Builtins
6122-----------------
6123
Guido van Rossumf8402962008-08-20 15:01:50 +00006124- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6125 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6126 extensions do not automatically benefit from the class attribute
6127 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6128 to their tp_flags field if they care. This is a backwards
6129 compatibility feature; in 3.0, all types will use the cache by
6130 default.
6131
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006132- Keyword arguments can now follow starred arguments. (``f(a, *args,
6133 keyword=23)`` is now valid syntax.)
6134
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006135- ctypes function pointers that are COM methods have a boolean True
6136 value again.
6137
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006138- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6139 by denying s# to parse objects that have a releasebuffer procedure,
6140 and introducing s*.
6141
Georg Brandl1e13ea92008-08-11 09:07:59 +00006142- Issue #3537: Fix an assertion failure when an empty but presized dict
6143 object was stored in the freelist.
6144
Mark Dickinsonb6467572008-08-04 21:30:09 +00006145- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6146 ValueError consistently across platforms.
6147
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006148- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6149 (64bit Unix, for example), unichr() would truncate its argument and return
6150 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6151
Neal Norwitze7d8be82008-07-31 17:17:14 +00006152- Apply security patches from Apple.
6153
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006154- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6155 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6156
Antoine Pitrou92f82162008-07-25 22:22:08 +00006157- Issue #1819: function calls with several named parameters are now on
6158 average 35% faster (as measured by pybench).
6159
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006160- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6161 the python debugger steps into a class statement: the free variables (local
6162 variables defined in an outer scope) would be deleted from the outer scope.
6163
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006164- Issue #2620: Overflow checking when allocating or reallocating memory
6165 was not always being done properly in some python types and extension
6166 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6167 all been updated to perform better checks and places in the code that
6168 would previously leak memory on the error path when such an allocation
6169 failed have been fixed.

6177 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6178
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006179- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6180 version reported by these tools does not necessarily follow the python
6181 version numbering scheme, so the module is less strict when parsing it.
6182
Nick Coghlanf70385a2008-08-18 12:42:46 +00006183- Issue #2235: Added Py3k warnings for types which will become unhashable
6184 under the stricter __hash__ inheritance rules in 3.0. Several types
6185 which did not meet the rules for hash invariants and were already
6186 unhashable in 3.0 have now been explicitly flagged as unhashable in
6187 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6188 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6189
Brett Cannon88f801d2008-08-18 00:46:22 +00006190- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6191 imported into the module but exposed as part of the module's API.
6192

6198
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006199- Issue #3575: Incremental decoder's decode function now takes bytearray
6200 by using 's*' instead of 't#'.
6201
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006202- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006203 fails unicode conversion on 2nd parameter. (windows only)
6204
Georg Brandl222e2082010-08-01 22:27:39 +00006205- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006206 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00006209 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006210
Facundo Batistaeb90b782008-08-16 14:44:07 +00006211- Issue #2776: fixed small issue when handling an URL with double slash
6212 after a 302 response in the case of not going through a proxy.
6213
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006214- Issue #2676: in the email package, content-type parsing was hanging on
6215 pathological input because of quadratic or exponential behaviour of a
6216 regular expression.
6217
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006218- Issue #3476: binary buffered reading through the new "io" library is now

6222 since mimetools itself is deprecated. Because modules are cached, all
6223 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00006259 asking for a specific length. This problem only affected files opened

6302 interaction with the tp_hash slot (added in 2.6b2) are now documented
6303
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006304- Issue #643841: The language reference now provides more detailed
6305 coverage of the lookup process for special methods. The disclaimers
6306 regarding lack of coverage of new-style classes have also been

6312
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006313*Release date: 17-Jul-2008*

6316-----------------
6317
Georg Brandl3e483f62008-07-16 22:57:41 +00006318- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6319 its methods now allow for items objects that can be converted to
6320 an integer using operator.index().
6321
Mark Dickinson64b7e502008-07-16 09:40:03 +00006322- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6323 produced a ValueError instead of giving the correct float.
6324
Eric Smitha5fa5a22008-07-16 00:11:49 +00006325- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6326 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6327
Mark Dickinson7103aa42008-07-15 19:08:33 +00006328- Issue #3008: the float type has a new instance method 'float.hex'
6329 and a new class method 'float.fromhex' to convert floating-point
6330 numbers to and from hexadecimal strings, respectively.
6331
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006332- Issue #2235: __hash__ is once again inherited by default. To allow
6333 collections.Hashable to remain meaningful in the presence of the
6334 default hash implementation (object.__hash__), it is now possible
6335 to explicit block inheritance of hash by setting __hash__=None at
6336 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6337 level.
6338
Nick Coghlanb028f502008-07-13 14:52:36 +00006339- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6340 the parent module cannot be found while performing an absolute import.
6341 This means that an incorrectly defined __package__ attribute will
6342 now only prevent relative imports in that module rather than causing
6343 all imports from that module to fail.
6344
Nick Coghlan14ff9942008-07-08 14:21:42 +00006345- Issue #2517: Allow unicode messages in Exceptions again by correctly
6346 bypassing the instance dictionary when looking up __unicode__ on
6347 new-style classes.

6350 set to a custom object whose write() method happens to install
6351 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006353- Issue #3088: Corrected a race condition in classes derived from
6354 threading.local: the first member set by a thread could be saved in
6355 another thread's dictionary.
6356
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006357- Issue #3004: Minor change to slice.indices(): the start and stop
6358 arguments are now treated identically, making the behaviour easier
6359 to describe and understand. For example, slice(None, -10,
6360 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6361 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6362 10, -1).
6363
Georg Brandl278fc502008-07-19 12:46:12 +00006364- Issue #3219: Calling a function with repeated keyword arguments,
6365 f(a=2, a=23), would not cause a syntax error. This was a regression
6366 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006367
Georg Brandl278fc502008-07-19 12:46:12 +00006368- Issue #2862: Make int and float freelist management consistent with
6369 other freelists. Changes their CompactFreeList apis into
6370 ClearFreeList apis and calls them via gc.collect().

6376 api functions without holding the GIL, which could lead to a fatal
6377 error when they failed.
6378
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006379- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006404- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6405 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006406 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006407 content-length. The problem had been corrected in the 2.4 branch, but never
6408 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006423- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6425
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006426- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Vinay Sajip9828b7e2008-06-17 11:04:02 +00006794- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006795 environment to control the '-arch' flags that are used to build
6796 an extension. This was added for compatibility with Apple's build
6797 of Python.
6798
6799- The bundled OSX-specific copy of libbffi is now in sync with the version
6800 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
6801
Georg Brandl25c34082008-08-18 23:09:49 +00006802- The threading module gained aliases for names that will be removed in the

6811
Brett Cannonb61d8012008-05-11 23:39:04 +00006812- ``Lib/lib-old`` is now added to sys.path.
6813
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006814- On MacOS X it is now possible to install the framework in 64-bit
6815 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006816 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006817
6818 This is controlled by the configure argument ``--with-universal-archs``:
6819
6820 - ``--with-universal-archs=all``: install 4-way universal
6821
6822 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6823
6824 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6825
6826 This option should be used in combination with ``--enable-universalsdk=``.
6827
6828 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 +00006878- Issue #1631171: Re-implement the 'warnings' module in C (the
6879 original Python code has been kept as backup). This will allow for
6880 using the 'warning's machinery in such places as the parser where
6881 use of pure Python code is not possible. Both the ``showarning()``
6882 and ``formatwarning()`` gain an optional 'line' argument which is
6883 not called by default for backwards-compatibility reasons. Setting
6884 ``warnings.showwarning()`` to an implementation that lacks support
6885 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006927- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006928 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006948- Issue #2550: The approach used by client/server code for obtaining
6949 ports to listen on in network-oriented tests has been refined in an
6950 effort to facilitate running multiple instances of the entire
6951 regression test suite in parallel without issue.
6952 test_support.bind_port() has been fixed such that it will always
6953 return a unique port -- which wasn't always the case with the
6954 previous implementation, especially if socket options had been set
6955 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6956 new implementation of bind_port() will actually raise an exception
6957 if it is passed an AF_INET/SOCK_STREAM socket with either the
6958 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6959 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6960 the socket it's been passed. This currently only applies to
6961 Windows. This option prevents any other sockets from binding to the
6962 host/port we've bound to, thus removing the possibility of the
6963 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6964 when a second SOCK_STREAM socket binds and accepts to a host/port
6965 that's already been bound by another socket. The optional preferred
6966 port parameter to bind_port() has been removed. Under no
6967 circumstances should tests be hard coding ports!
6968
6969 test_support.find_unused_port() has also been introduced, which will
6970 pass a temporary socket object to bind_port() in order to obtain an
6971 unused port. The temporary socket object is then closed and
6972 deleted, and the port is returned. This method should only be used
6973 for obtaining an unused port in order to pass to an external program
6974 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6975 a parameter to a server-oriented class that doesn't give you direct
6976 access to the underlying socket used.
6977
6978 Finally, test_support.HOST has been introduced, which should be used
6979 for the host argument of any relevant socket calls (i.e. bind and
6980 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006981
6982 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006983 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006984 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6985 test_asynchat and test_socket_ssl.
6986
Georg Brandl3ee81df2008-05-17 18:14:43 +00006987 It is now possible for multiple instances of the regression test
6988 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007267- Added the future_builtins module, which contains hex() and oct().
7268 These are the PEP 3127 version of these functions, designed to be
7269 compatible with the hex() and oct() builtins from Python 3.0. They
7270 differ slightly in their output formats from the existing, unchanged
7271 Python 2.6 builtins. The expected usage of the future_builtins
7272 module is:
7273 from future_builtins import hex, oct
7274
Eric Smith7ef40bf2008-02-20 23:34:22 +00007275- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7276 exponents for exponents with absolute value < 100. Follows C99
7277 standard. This is a change on Windows, which would use 3 digits.
7278 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7279 so that any alterations it does to the resulting string will be
7280 available in stringlib/formatter.h (for float.__format__).
7281
Eric Smith5a3c1352008-02-19 13:21:56 +00007282- Implemented PEP 3101, Advanced String Formatting. This adds a new
7283 builtin format(); a format() method for str and unicode; a
7284 __format__() method to object, str, unicode, int, long, float, and
7285 datetime; the class string.Formatter; and the C API
7286 PyObject_Format().
7287
Georg Brandl3ee81df2008-05-17 18:14:43 +00007288- Fixed several potential crashes, all caused by specially crafted
7289 __del__ methods exploiting objects in temporarily inconsistent
7290 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007292- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007293 prevent a possible crash: an Abstract Base Class would try to access
7294 a slot on a registered virtual subclass.

7300 in order to allow pymalloc to free more arenas. Python may give back
7301 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007302
Georg Brandl3ee81df2008-05-17 18:14:43 +00007303- Issue #2045: Fix an infinite recursion triggered when printing a
7304 subclass of collections.defaultdict, if its default_factory is set
7305 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007306
Christian Heimesf75dbef2008-02-08 00:11:31 +00007307- Fixed a minor memory leak in dictobject.c. The content of the free
7308 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00007310- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007311 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007312
Georg Brandl3ee81df2008-05-17 18:14:43 +00007313- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7314 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007315 to compact the internal free lists of pre-allocted ints and floats.
7316
Georg Brandl3ee81df2008-05-17 18:14:43 +00007317- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7318 calls. Python expected the return type int but the fork familie
7319 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007320
Georg Brandl3ee81df2008-05-17 18:14:43 +00007321- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7322 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007323
Georg Brandl3ee81df2008-05-17 18:14:43 +00007324- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7325 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007326
Georg Brandl3ee81df2008-05-17 18:14:43 +00007327- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7328 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00007330- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7331 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007332
Georg Brandl3ee81df2008-05-17 18:14:43 +00007333- Patch #1473257: generator objects gain a gi_code attribute. This is
7334 the same object as the func_code attribute of the function that
7335 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007336
Georg Brandl3ee81df2008-05-17 18:14:43 +00007337- Issue #1920: "while 0" statements were completely removed by the
7338 compiler, even in the presence of an "else" clause, which is
7339 supposed to be run when the condition is false. Now the compiler
7340 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007341
Guido van Rossumeead05f2008-01-24 18:21:02 +00007342- A few crashers fixed: weakref_in_del.py (issue #1377858);
7343 loosing_dict_ref.py (issue #1303614, test67.py);
7344 borrowed_ref_[34].py (not in tracker).
7345
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007346- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007347 suppressed while an extension is loaded by calling SetErrorMode in
7348 dynload_win.c. The error is still reported properly.
7349
Georg Brandl3ee81df2008-05-17 18:14:43 +00007350- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007351 several extension methods and modules do not work without unicode
7352 support.
7353
Georg Brandl26543b12008-01-21 18:36:51 +00007354- Issue #1882: when compiling code from a string, encoding cookies in the
7355 second line of code were not always recognized correctly.
7356
Georg Brandl14404b62008-01-19 19:27:05 +00007357- Issue #1679: "0x" was taken as a valid integer literal.
7358
Georg Brandl6caad7d2008-01-26 14:19:22 +00007359- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007360 added.
7361
Christian Heimesc94e2b52008-01-14 04:13:37 +00007362- sys.float_info / PyFloat_GetInfo: The floating point information
7363 object was converted from a dict to a specialized structseq object.
7364
Georg Brandl3ee81df2008-05-17 18:14:43 +00007365- Patch #1816: Added sys.flags structseq. It exposes the status of
7366 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007367
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368- Objects/structseq.c: Implemented new structseq representation. The
7369 patch makes structseqs (e.g. the return value of os.stat) more
7370 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007371
Georg Brandl3ee81df2008-05-17 18:14:43 +00007372- Patch #1700288: added a type attribute cache that caches method
7373 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007374
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007375- Bug #1776: __import__() no longer accepts filenames on any platform.
7376 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007377
Georg Brandlaed6c662008-01-07 17:25:53 +00007378- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7379
Georg Brandl3ee81df2008-05-17 18:14:43 +00007380- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7381 envvar and sys.dont_write_bytecode attribute. All these can be set
7382 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007383
Georg Brandl3ee81df2008-05-17 18:14:43 +00007384- Improve some exception messages when Windows fails to load an
7385 extension module. Now we get for example '%1 is not a valid Win32
7386 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007387
Georg Brandl3ee81df2008-05-17 18:14:43 +00007388- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007390- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7391 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007392
Christian Heimes0a8143f2007-12-18 23:22:54 +00007393- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007394 and INF. float("nan"), float("inf") and float("-inf") now work on
7395 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007396
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Compiler now generates simpler and faster code for dictionary
7398 literals. The oparg for BUILD_MAP now indicates an estimated
7399 dictionary size. There is a new opcode, STORE_MAP, for adding
7400 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007401
Georg Brandl3ee81df2008-05-17 18:14:43 +00007402- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007410- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007411 SystemError.
7412
Nick Coghlanef01d822007-12-03 12:55:17 +00007413- PEP 366: Allow explicit relative imports when executing modules
7414 inside packages with the -m switch via a new module level
7415 __package__ attribute.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007429- Patch #1739468: Directories and zipfiles containing a __main__.py
7430 file can now be directly executed by passing their name to the
7431 interpreter. The directory/zipfile is automatically inserted as the
7432 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007433
Georg Brandl3ee81df2008-05-17 18:14:43 +00007434- Issue #1265: Fix a problem with sys.settrace, if the tracing
7435 function uses a generator expression when at the same time the
7436 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007437
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007438- sets and frozensets now have an isdisjoint() method.
7439
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007440- optimize the performance of builtin.sum().
7441
Neal Norwitz44f326e2007-10-05 05:29:17 +00007442- Fix warnings found by the new version of the Coverity checker.
7443
Georg Brandl21e99f42010-03-07 15:23:59 +00007444- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007445 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7446 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007447
Georg Brandl3ee81df2008-05-17 18:14:43 +00007448- Issue #1686386: Tuple's tp_repr did not take into account the
7449 possibility of having a self-referential tuple, which is possible
7450 from C code. Nor did object's tp_str consider that a type's tp_str
7451 could do something that could lead to an inifinite recursion.
7452 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7453 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007454
Georg Brandl3ee81df2008-05-17 18:14:43 +00007455- Issue #1164: It was possible to trigger deadlock when using the
7456 'print' statement to write to a file since the GIL was not released
7457 as needed. Now PyObject_Print() does the right thing along with
7458 various tp_print implementations of the built-in types and those in
7459 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007460
Georg Brandl3ee81df2008-05-17 18:14:43 +00007461- Issue #1147: Exceptions were directly allowing string exceptions in
7462 their throw() method even though string exceptions no longer
7463 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007464
Georg Brandl3ee81df2008-05-17 18:14:43 +00007465- Issue #1096: Prevent a segfault from getting the repr of a very
7466 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007467
Brett Cannon1e534b52007-09-07 04:18:30 +00007468- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007469 PyObject_Call() never calling back out to Python code to trigger
7470 recursion depth updates/checks. Required the creation of a static
7471 RuntimeError instance in case normalizing an exception put the
7472 recursion check value past its limit. Fixes crashers
7473 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007474
Georg Brandl3ee81df2008-05-17 18:14:43 +00007475- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007488- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007489 __*__ attributes. (Some already existed, e.g., __doc__ and
7490 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007491
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007492- Add -3 option to the interpreter to warn about features that are
7493 deprecated and will be changed/removed in Python 3.0.
7494
Georg Brandl2134e752007-05-21 20:34:16 +00007495- Patch #1686487: you can now pass any mapping after '**' in function
7496 calls.
7497
Collin Winter62903052007-05-18 23:11:24 +00007498- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007499 "except E as target:". This is to provide forwards compatibility
7500 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007502- Deprecate BaseException.message as per PEP 352.
7503
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007505 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007506
Vinay Sajip8549ce32007-05-06 17:53:37 +00007507- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007508 setting a plain string, ie don't expand to single letter identifiers.
7509
Raymond Hettinger13936692007-04-11 18:40:58 +00007510- Request #1191699: Slices can now be pickled.
7511
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007512- Request #1193128: str.translate() now allows a None argument for
7513 translations that only remove characters without re-mapping the
7514 remaining characters.
7515
Georg Brandl5cb76c12007-03-21 09:00:39 +00007516- Patch #1682205: a TypeError while unpacking an iterable is no longer
7517 masked by a generic one with the message "unpack non-sequence".
7518
Neal Norwitzaa754b72007-03-21 06:39:48 +00007519- Remove unused file Python/fmod.c.
7520
Guido van Rossum143b5642007-03-23 04:58:42 +00007521- Bug #1683368: The object.__init__() and object.__new__() methods are
7522 now stricter in rejecting excess arguments. The only time when
7523 either allows excess arguments is when it is not overridden and the
7524 other one is. For backwards compatibility, when both are
7525 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007526 warning later). Also, type.__init__() insists on the same signature
7527 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007528
Georg Brandl3ee81df2008-05-17 18:14:43 +00007529- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7530 object to complex using its __complex__() method before falling back
7531 to the __float__() method. Therefore, the functions in the cmath
7532 module now can operate on objects that define a __complex__()
7533 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007535- Patch #1623563: allow __class__ assignment for classes with
7536 __slots__. The old and the new class are still required to have the
7537 same slot names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008607 time so that opening a database previously created with the DB_DUP
8608 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8609 opens. Specifically: dictionary assignment to a DB object will
8610 replace all values for a given key when the database allows
8611 duplicate values. DB users should use DB.put(k, v) when they want
8612 to store duplicates; not DB[k] = v.

8619 characters with ASCII value less than 32. Also, it correctly quotes
8620 dots only if they occur on a single line, as opposed to the previous
8621 behavior of quoting dots if they are the second character of any
8622 line.
