570- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
571 and later systems as is currently done for Python 3.x installers.
572 For 2.7.7 only, we will provide three installers:
573 the legacy deprecated 10.3+ 32-bit-only format;
574 the newer 10.5+ 32-bit-only format;
575 and the unchanged 10.6+ 64-/32-bit format.
576 Although binary installers will no longer be available from
577 python.org as of 2.7.8, it will still be possible to build from
578 source on 10.3.9 and 10.4 systems if necessary.

Ned Deily8e60f6e2013-05-30 00:14:29 -0700894- Issue #18098: The deprecated OS X Build Applet.app fails to build on

902 64-bit/32-bit installer for 10.6+. It is no longer necessary
903 to install a third-party version of Tcl/Tk 8.5 to work around the
904 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
905 and later releases.
906
Ned Deilyf84b5312013-10-25 00:44:46 -0700907- Issue #19019: Change the OS X installer build script to use CFLAGS instead
908 of OPT for special build options. By setting OPT, some compiler-specific
909 options like -fwrapv were overridden and thus not used, which could result
910 in broken interpreters when building with clang.

1958 32-bit-only installer Pythons on systems with Xcode 4 (currently
1959 OS X 10.8, 10.7, and optionally 10.6).
1960 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1961 * Since Xcode 4 removes ppc support, extension module builds now
1962 check for ppc compiler support and by default remove ppc and
1963 ppc64 archs when they are not available.
1964 * Extension module builds now revert to using system installed
1965 headers and libs (/usr and /System/Library) if the SDK used
1966 to build the interpreter is not installed or has moved.
1967 * Try to avoid building extension modules with deprecated
1968 and problematic Apple llvm-gcc compiler. If original compiler
1969 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002393- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002394 has left two versions of customize_compiler, the original in
2395 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002400- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2401 Distutils-based packages with C extension modules may fail because
2402 Apple has removed gcc-4.2, the version used to build python.org
2403 64-bit/32-bit Pythons. If the user does not explicitly override
2404 the default C compiler by setting the CC environment variable,
2405 Distutils will now attempt to compile extension modules with clang
2406 if gcc-4.2 is required but not found. Also as a convenience, if
2407 the user does explicitly set CC, substitute its value as the default
2408 compiler in the Distutils LDSHARED configuration variable for OS X.
2409 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2410 SDK, neither of which are available in Xcode 4. This change does not
2411 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002661- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2662 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2663 interpreter process. This could cause failures in non-Distutils subprocesses
2664 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002665 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002666 deployment target only in the environment of each build subprocess. It is
2667 still possible to globally override the default by setting
2668 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2669 greater or equal to the default value, the value with which the interpreter
2670 was built.

2699 updating the check interval, so if the user decreases the check interval,
2700 the ticker doesn't have to wind down to zero from the old starting point
2701 before the new interval takes effect. And if the user increases the
2702 interval, it makes sure the new limit takes effect right away rather have an
2703 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003528- Issue #9869: Make long() and PyNumber_Long return something of type
3529 long for a class whose __long__ method returns a plain int. This
3530 fixes an interpreter crash when initializing an instance of a long
3531 subclass from an object whose __long__ method returns a plain int.

3536 thread-local storage key.
3537
Victor Stinnercaafd772010-09-08 10:51:01 +00003538- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3539 encoding and errors attributes instead of using utf-8 in strict mode, to get
3540 the same behaviour than the print statement.

3682
Raymond Hettinger20397532010-09-12 02:11:45 +00003683- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3684 This prevents user-created self-referencing ordered dictionaries from
3685 becoming permanently uncollectable GC garbage. The downside is that
3686 removing __del__ means that the internal doubly-linked list has to wait for
3687 GC collection rather than freeing memory immediately when the refcnt drops
3688 to zero.
3689

3693
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003694- Issue #9792: In case of connection failure, socket.create_connection()
3695 would swallow the exception and raise a new one, making it impossible
3696 to fetch the original errno, or to filter timeout errors. Now the
3697 original error is re-raised.

3701 be updated back after the system call. Original patch by Brian Brazil.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004146- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4147 start byte and the continuation byte(s) are now considered invalid, instead
4148 of the number of bytes specified by the start byte.
4149 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4150 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4151 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4162 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4548 with a non-empty format string. This is an effort to future-proof user
4549 code. If a derived class does not currently implement __format__ but later
4550 adds its own __format__, it would most likely break user code that had

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005044- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005045 file position when calling `truncate()`. It would previously change the file
5046 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005047 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00005049- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5050 class used to represent files stored inside an archive. The new
5051 implementation is significantly faster and can be wrapped in a
5052 ``io.BufferedReader`` object for more speedups. It also solves an issue
5053 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5142-----------------
5143
Georg Brandlba83f822010-03-14 09:50:54 +00005144- The ``__complex__()`` method is now looked up on the class of instances to
5145 make it consistent with other special methods.

5149
Mark Dickinson1b34d252010-01-01 17:27:30 +00005150- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005151 DeprecationWarning when passed a float argument where an integer was expected.
5152 These functions and methods now raise TypeError instead. The majority of the
5153 effects of this change are in the extension modules, but some core functions
5154 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5155 and many unicode/str methods.

5169 of integers: the result of a/b is now correctly rounded for ints a and b (at
5170 least on IEEE 754 platforms), and in particular does not depend on the
5171 internal representation of a long.

5179
Georg Brandlba83f822010-03-14 09:50:54 +00005180 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005319- Issue #3382: 'F' formatting for float and complex now convert the result to
5320 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5321 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005322
Georg Brandlba83f822010-03-14 09:50:54 +00005323- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5324 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005325
Georg Brandlba83f822010-03-14 09:50:54 +00005326- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5327 1e-100 used to raise OverflowError, but now gives the requested 120
5328 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005336
Georg Brandlba83f822010-03-14 09:50:54 +00005337- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5338 decimal string that's guaranteed to round back to x under correct rounding
5339 (with round-half-to-even rounding mode). Previously it gave a string based on
5340 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5341 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5342 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005343
Georg Brandlba83f822010-03-14 09:50:54 +00005344- Issue #7117: On almost all platforms: float-to-string and string-to-float
5345 conversions within Python are now correctly rounded. Places these conversions
5346 occur include: str for floats and complex numbers; the float and complex
5347 constructors; old-style and new-style numeric formatting; serialization and
5348 deserialization of floats and complex numbers using marshal, pickle and json;
5349 parsing of float and imaginary literals in Python code; Decimal-to-float
5350 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005351
Georg Brandlba83f822010-03-14 09:50:54 +00005352 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5353 providing correctly-rounded strtod and dtoa C functions. This code is
5354 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5355 the C compiler. There may be a small number of platforms on which correct
5356 operation of this code cannot be guaranteed, so the code is not used: notably,
5357 this applies to platforms where the C double format is not IEEE 754 binary64,
5358 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5359 and Python's configure script is unable to determine how to change the FPU
5360 precision. On these platforms conversions use the platform strtod and dtoa,
5361 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005362
Georg Brandlba83f822010-03-14 09:50:54 +00005363- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5364 uses the correctly-rounded string <-> float conversions described above (when
5365 available), and so produces correctly rounded results that will display nicely
5366 under the float repr. There are two related small changes: (1) round now
5367 accepts any class with an ``__index__()`` method for its second argument (but
5368 no longer accepts floats for the second argument), and (2) an excessively
5369 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5370 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005511- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005512
Georg Brandlba83f822010-03-14 09:50:54 +00005513 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5514 (2) parsing of strings representing infinities and nans was locale aware; and
5515 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005517- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5518 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5519 but with at least one decimal point and with a default precision
5520 of 12. Previously, the behavior the same but with a default precision of 6.
5521 This more closely matches ``str()``, and reduces surprises when adding
5522 alignment flags to the empty presentation type. This also affects the new
5523 complex.__format__ in the same way.
5524
5525- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5526 classtype's, even if it was None. property now inserts the __doc__ into the
5527 subclass instance __dict__.

5597 internal representation of integers, for performance reasons. Base 2**30 is
5598 enabled by default on 64-bit machines. Add --enable-big-digits option to

5749 this code path is really executed because I cannot move to such directory on

5753 element is temporarily replaced with an equivalent frozenset. But the
5754 eventual KeyError would always report the empty ``frozenset()`` as the missing
5755 key. Now it correctly refers to the initial element.

5776 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5777 step. This avoids problems with counting UTF-8 bytes that ignores the effect

5785 gives improved memory leak detection when running under Valgrind, while taking
5786 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006953 - If x is not an int, long or float, then packing x will always result in
6954 struct.error. Previously an x with an __int__ method could be packed by
6955 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6956 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6957 neither __int__ nor __long__, TypeError used to be raised (with a
6958 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6959 struct.error in other cases.

6962 argument with an __int__ method can be packed, but use of this feature
6963 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00007012 leak-chasing test runs give sensible results. The previous method of reaping
7013 threads could return successfully while some Thread objects were still
7014 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00007015
Georg Brandlba83f822010-03-14 09:50:54 +00007016- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00007033 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00007134- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00007135 AttributeError instead of RuntimeError, depending in which C API call
7136 exactly the recursion limit is exceeded. Consequently, both exception types
7137 are caught and silenced.

7153
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007154- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7155
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007156- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7157 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7158 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7159 ``printf`` function, whereas PyString_FromFormat has an independent
7160 implementation and uses "%zd" on all platforms for size_t values.
7161 This makes a difference on win64, where ``printf`` needs "%Id" to display
7162 64bit values.
7163
Benjamin Peterson97179b02008-09-09 20:55:01 +00007164- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7165 error.
7166
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007167- Issue #3777: long() applied to a float object now always return a long
7168 object; previously an int would be returned for small values. the __long__
7169 method is allowed to return either an int or a long, but the behaviour of
7170 float objects should not change to respect backward compatibility.
7171
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007172- Issue #3751: str.rpartition would perform a left-partition when called with
7173 a unicode argument.
7174
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007175- Issue #3683: Fix compilation when --without-threads is given.
7176
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007177- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007178 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007179 was correctly parsed but parsing of subsequent arguments failed.
7180
Vinay Sajip35e3b032008-09-01 14:33:59 +00007181- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007182 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7183 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7184 when given a tuple of classes as second argument, were looking up
7185 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7186 type object.
7187
Neal Norwitz18aa3882008-08-24 05:04:52 +00007188- Fix crashes on memory allocation failure found with failmalloc.
7189
7190- Fix memory leaks found with valgrind and update suppressions file.
7191
7192- Fix compiler warnings in opt mode which would lead to invalid memory reads.
7193
7194- Fix problem using wrong name in decimal module reported by pychecker.
7195
Christian Heimes7d4c3172008-08-22 19:47:25 +00007196- Silenced another compiler warning about a used but not defined
7197 function 'stringlib_contains_obj'.
7198
Benjamin Peterson712ee922008-08-24 18:10:20 +00007199- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
7200 ``__delslice__``.
7201
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00007202- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
7203 library targets in the Makefile.
7204
Gregory P. Smith980b99b2008-09-07 05:15:18 +00007205- Issue #1204: The configure script now tests for additional libraries
7206 that may be required when linking against readline. This fixes issues
7207 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

7218 stack usage in the case of deeply nested objects.
7219

Nick Coghland2e09382008-09-11 12:11:06 +00007230- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00007231 return a list or None rather than a custom object.
7232
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00007233- Issue #1638033: Cookie.Morsel gained the httponly attribute.
7234
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00007235- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Georg Brandl222e2082010-08-01 22:27:39 +00007256- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00007257 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7258 for catch_warnings() also led to an improvement in the raising of a
7259 DeprecationWarning related to warnings.warn_explicit().
7260
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007261- The deprecation warnings for the old camelCase threading API were removed.

7283
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007284- Issue #2975: When compiling several extension modules with Visual Studio 2008
7285 from the same python interpreter, some environment variables would grow
7286 without limit.
7287
Benjamin Peterson37346b22008-08-23 20:27:43 +00007288- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7289 exploitation of poor argument checking.
7290
Gerhard Häringef2276b2008-09-12 13:54:06 +00007291- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

7304 wrapper for warnings.catch_warnings() that makes it easier to check
7305 that expected warning messages are being reported.
7306

7331-----------------
7332
Guido van Rossumf8402962008-08-20 15:01:50 +00007333- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7334 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7335 extensions do not automatically benefit from the class attribute
7336 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7337 to their tp_flags field if they care. This is a backwards
7338 compatibility feature; in 3.0, all types will use the cache by
7339 default.
7340
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007341- Keyword arguments can now follow starred arguments. (``f(a, *args,
7342 keyword=23)`` is now valid syntax.)
7343
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007344- ctypes function pointers that are COM methods have a boolean True
7345 value again.
7346
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007347- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7348 by denying s# to parse objects that have a releasebuffer procedure,
7349 and introducing s*.
7350
Georg Brandl1e13ea92008-08-11 09:07:59 +00007351- Issue #3537: Fix an assertion failure when an empty but presized dict
7352 object was stored in the freelist.
7353
Mark Dickinsonb6467572008-08-04 21:30:09 +00007354- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7355 ValueError consistently across platforms.
7356
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007357- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7358 (64bit Unix, for example), unichr() would truncate its argument and return
7359 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7360
Neal Norwitze7d8be82008-07-31 17:17:14 +00007361- Apply security patches from Apple.
7362
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007363- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7364 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7365
Antoine Pitrou92f82162008-07-25 22:22:08 +00007366- Issue #1819: function calls with several named parameters are now on
7367 average 35% faster (as measured by pybench).
7368
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007369- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7370 the python debugger steps into a class statement: the free variables (local
7371 variables defined in an outer scope) would be deleted from the outer scope.
7372
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007373- Issue #2620: Overflow checking when allocating or reallocating memory
7374 was not always being done properly in some python types and extension
7375 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7376 all been updated to perform better checks and places in the code that
7377 would previously leak memory on the error path when such an allocation
7378 failed have been fixed.

7384
Benjamin Petersone977ad42008-08-20 01:42:01 +00007385- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7386 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7387
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007388- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7389 version reported by these tools does not necessarily follow the python
7390 version numbering scheme, so the module is less strict when parsing it.
7391
Nick Coghlanf70385a2008-08-18 12:42:46 +00007392- Issue #2235: Added Py3k warnings for types which will become unhashable
7393 under the stricter __hash__ inheritance rules in 3.0. Several types
7394 which did not meet the rules for hash invariants and were already
7395 unhashable in 3.0 have now been explicitly flagged as unhashable in
7396 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7397 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7398
Brett Cannon88f801d2008-08-18 00:46:22 +00007399- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7400 imported into the module but exposed as part of the module's API.
7401
Brett Cannon7b96f072008-08-18 00:41:11 +00007402- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007406- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7407
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007408- Issue #3575: Incremental decoder's decode function now takes bytearray
7409 by using 's*' instead of 't#'.

7512
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007513- Issue #643841: The language reference now provides more detailed

7526
Georg Brandl3e483f62008-07-16 22:57:41 +00007527- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7528 its methods now allow for items objects that can be converted to
7529 an integer using operator.index().
7530
Mark Dickinson64b7e502008-07-16 09:40:03 +00007531- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7532 produced a ValueError instead of giving the correct float.
7533
Eric Smitha5fa5a22008-07-16 00:11:49 +00007534- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7535 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7536
Mark Dickinson7103aa42008-07-15 19:08:33 +00007537- Issue #3008: the float type has a new instance method 'float.hex'
7538 and a new class method 'float.fromhex' to convert floating-point
7539 numbers to and from hexadecimal strings, respectively.
7540
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007541- Issue #2235: __hash__ is once again inherited by default. To allow
7542 collections.Hashable to remain meaningful in the presence of the
7543 default hash implementation (object.__hash__), it is now possible
7544 to explicit block inheritance of hash by setting __hash__=None at
7545 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7546 level.
7547
Nick Coghlanb028f502008-07-13 14:52:36 +00007548- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7549 the parent module cannot be found while performing an absolute import.
7550 This means that an incorrectly defined __package__ attribute will
7551 now only prevent relative imports in that module rather than causing
7552 all imports from that module to fail.
7553
Nick Coghlan14ff9942008-07-08 14:21:42 +00007554- Issue #2517: Allow unicode messages in Exceptions again by correctly

7564 another thread's dictionary.
7565
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007566- Issue #3004: Minor change to slice.indices(): the start and stop
7567 arguments are now treated identically, making the behaviour easier
7568 to describe and understand. For example, slice(None, -10,
7569 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7570 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7571 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007573- Issue #3219: Calling a function with repeated keyword arguments,

7575 from 2.4 caused by the switch to the new compiler.

7614 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007615 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007616 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00008021- On MacOS X it is now possible to install the framework in 64-bit
8022 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008023 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008024
8025 This is controlled by the configure argument ``--with-universal-archs``:
8026
8027 - ``--with-universal-archs=all``: install 4-way universal
8028
8029 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8030
8031 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8032
8033 This option should be used in combination with ``--enable-universalsdk=``.
8034
8035 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 +00008084- Issue #1631171: Re-implement the 'warnings' module in C (the
8085 original Python code has been kept as backup). This will allow for
8086 using the 'warning's machinery in such places as the parser where
8087 use of pure Python code is not possible. Both the ``showarning()``
8088 and ``formatwarning()`` gain an optional 'line' argument which is
8089 not called by default for backwards-compatibility reasons. Setting
8090 ``warnings.showwarning()`` to an implementation that lacks support
8091 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008154- Issue #2550: The approach used by client/server code for obtaining
8155 ports to listen on in network-oriented tests has been refined in an
8156 effort to facilitate running multiple instances of the entire
8157 regression test suite in parallel without issue.
8158 test_support.bind_port() has been fixed such that it will always
8159 return a unique port -- which wasn't always the case with the
8160 previous implementation, especially if socket options had been set
8161 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8162 new implementation of bind_port() will actually raise an exception
8163 if it is passed an AF_INET/SOCK_STREAM socket with either the
8164 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8165 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8166 the socket it's been passed. This currently only applies to
8167 Windows. This option prevents any other sockets from binding to the
8168 host/port we've bound to, thus removing the possibility of the
8169 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8170 when a second SOCK_STREAM socket binds and accepts to a host/port
8171 that's already been bound by another socket. The optional preferred
8172 port parameter to bind_port() has been removed. Under no
8173 circumstances should tests be hard coding ports!
8174
8175 test_support.find_unused_port() has also been introduced, which will
8176 pass a temporary socket object to bind_port() in order to obtain an
8177 unused port. The temporary socket object is then closed and
8178 deleted, and the port is returned. This method should only be used
8179 for obtaining an unused port in order to pass to an external program
8180 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8181 a parameter to a server-oriented class that doesn't give you direct
8182 access to the underlying socket used.
8183
8184 Finally, test_support.HOST has been introduced, which should be used
8185 for the host argument of any relevant socket calls (i.e. bind and
8186 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008187
8188 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008189 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008190 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8191 test_asynchat and test_socket_ssl.
8192
Georg Brandl3ee81df2008-05-17 18:14:43 +00008193 It is now possible for multiple instances of the regression test
8194 suite to run in parallel without issue.

8250 Plane. This affected raw unicode literals and the
8251 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8252 this case, like normal unicode literals and the 'unicode-escape'
8253 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00008473- Added the future_builtins module, which contains hex() and oct().
8474 These are the PEP 3127 version of these functions, designed to be
8475 compatible with the hex() and oct() builtins from Python 3.0. They
8476 differ slightly in their output formats from the existing, unchanged
8477 Python 2.6 builtins. The expected usage of the future_builtins
8478 module is:
8479 from future_builtins import hex, oct
8480
Eric Smith7ef40bf2008-02-20 23:34:22 +00008481- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8482 exponents for exponents with absolute value < 100. Follows C99
8483 standard. This is a change on Windows, which would use 3 digits.
8484 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8485 so that any alterations it does to the resulting string will be
8486 available in stringlib/formatter.h (for float.__format__).
8487
Eric Smith5a3c1352008-02-19 13:21:56 +00008488- Implemented PEP 3101, Advanced String Formatting. This adds a new
8489 builtin format(); a format() method for str and unicode; a
8490 __format__() method to object, str, unicode, int, long, float, and
8491 datetime; the class string.Formatter; and the C API
8492 PyObject_Format().
8493
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494- Fixed several potential crashes, all caused by specially crafted
8495 __del__ methods exploiting objects in temporarily inconsistent

Georg Brandl3ee81df2008-05-17 18:14:43 +00008505- Clear all free lists during a gc.collect() of the highest generation
8506 in order to allow pymalloc to free more arenas. Python may give back
8507 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008508
Georg Brandl3ee81df2008-05-17 18:14:43 +00008509- Issue #2045: Fix an infinite recursion triggered when printing a
8510 subclass of collections.defaultdict, if its default_factory is set
8511 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008512
Christian Heimesf75dbef2008-02-08 00:11:31 +00008513- Fixed a minor memory leak in dictobject.c. The content of the free
8514 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008523- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8524 calls. Python expected the return type int but the fork familie
8525 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008526
Georg Brandl3ee81df2008-05-17 18:14:43 +00008527- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008539- Patch #1473257: generator objects gain a gi_code attribute. This is
8540 the same object as the func_code attribute of the function that
8541 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008542
Georg Brandl3ee81df2008-05-17 18:14:43 +00008543- Issue #1920: "while 0" statements were completely removed by the
8544 compiler, even in the presence of an "else" clause, which is
8545 supposed to be run when the condition is false. Now the compiler
8546 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008547
Guido van Rossumeead05f2008-01-24 18:21:02 +00008548- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008552- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008553 suppressed while an extension is loaded by calling SetErrorMode in
8554 dynload_win.c. The error is still reported properly.
8555
Georg Brandl3ee81df2008-05-17 18:14:43 +00008556- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008557 several extension methods and modules do not work without unicode
8558 support.
8559

8564
Georg Brandl6caad7d2008-01-26 14:19:22 +00008565- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008566 added.
8567
Christian Heimesc94e2b52008-01-14 04:13:37 +00008568- sys.float_info / PyFloat_GetInfo: The floating point information
8569 object was converted from a dict to a specialized structseq object.
8570
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571- Patch #1816: Added sys.flags structseq. It exposes the status of
8572 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008573
Georg Brandl3ee81df2008-05-17 18:14:43 +00008574- Objects/structseq.c: Implemented new structseq representation. The
8575 patch makes structseqs (e.g. the return value of os.stat) more
8576 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008577
Georg Brandl3ee81df2008-05-17 18:14:43 +00008578- Patch #1700288: added a type attribute cache that caches method
8579 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008580
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008581- Bug #1776: __import__() no longer accepts filenames on any platform.
8582 The first parameter to __import__() must be a valid module name.

8587 envvar and sys.dont_write_bytecode attribute. All these can be set
8588 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008589
Georg Brandl3ee81df2008-05-17 18:14:43 +00008590- Improve some exception messages when Windows fails to load an
8591 extension module. Now we get for example '%1 is not a valid Win32
8592 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008593

Christian Heimes0a8143f2007-12-18 23:22:54 +00008599- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008600 and INF. float("nan"), float("inf") and float("-inf") now work on
8601 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008602
Georg Brandl3ee81df2008-05-17 18:14:43 +00008603- Compiler now generates simpler and faster code for dictionary
8604 literals. The oparg for BUILD_MAP now indicates an estimated
8605 dictionary size. There is a new opcode, STORE_MAP, for adding
8606 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008635- Patch #1739468: Directories and zipfiles containing a __main__.py
8636 file can now be directly executed by passing their name to the
8637 interpreter. The directory/zipfile is automatically inserted as the
8638 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008639
Georg Brandl3ee81df2008-05-17 18:14:43 +00008640- Issue #1265: Fix a problem with sys.settrace, if the tracing
8641 function uses a generator expression when at the same time the
8642 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008643
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008644- sets and frozensets now have an isdisjoint() method.
8645
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008646- optimize the performance of builtin.sum().
8647
Neal Norwitz44f326e2007-10-05 05:29:17 +00008648- Fix warnings found by the new version of the Coverity checker.
8649
Georg Brandl21e99f42010-03-07 15:23:59 +00008650- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008651 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8652 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008653
Georg Brandl3ee81df2008-05-17 18:14:43 +00008654- Issue #1686386: Tuple's tp_repr did not take into account the
8655 possibility of having a self-referential tuple, which is possible
8656 from C code. Nor did object's tp_str consider that a type's tp_str
8657 could do something that could lead to an inifinite recursion.
8658 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8659 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008660
Georg Brandl3ee81df2008-05-17 18:14:43 +00008661- Issue #1164: It was possible to trigger deadlock when using the
8662 'print' statement to write to a file since the GIL was not released
8663 as needed. Now PyObject_Print() does the right thing along with
8664 various tp_print implementations of the built-in types and those in
8665 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008666
Georg Brandl3ee81df2008-05-17 18:14:43 +00008667- Issue #1147: Exceptions were directly allowing string exceptions in
8668 their throw() method even though string exceptions no longer
8669 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008670
Georg Brandl3ee81df2008-05-17 18:14:43 +00008671- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00008673
Brett Cannon1e534b52007-09-07 04:18:30 +00008674- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008675 PyObject_Call() never calling back out to Python code to trigger
8676 recursion depth updates/checks. Required the creation of a static
8677 RuntimeError instance in case normalizing an exception put the
8678 recursion check value past its limit. Fixes crashers
8679 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008680

Neal Norwitz0ac60192007-05-27 04:08:54 +00008694- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008695 __*__ attributes. (Some already existed, e.g., __doc__ and
8696 __name__.)

8700
Georg Brandl2134e752007-05-21 20:34:16 +00008701- Patch #1686487: you can now pass any mapping after '**' in function
8702 calls.
8703
Collin Winter62903052007-05-18 23:11:24 +00008704- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008705 "except E as target:". This is to provide forwards compatibility
8706 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008713- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008714 setting a plain string, ie don't expand to single letter identifiers.
8715
Raymond Hettinger13936692007-04-11 18:40:58 +00008716- Request #1191699: Slices can now be pickled.
8717
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008718- Request #1193128: str.translate() now allows a None argument for
8719 translations that only remove characters without re-mapping the
8720 remaining characters.
8721
Georg Brandl5cb76c12007-03-21 09:00:39 +00008722- Patch #1682205: a TypeError while unpacking an iterable is no longer

8726
Guido van Rossum143b5642007-03-23 04:58:42 +00008727- Bug #1683368: The object.__init__() and object.__new__() methods are
8728 now stricter in rejecting excess arguments. The only time when
8729 either allows excess arguments is when it is not overridden and the
8730 other one is. For backwards compatibility, when both are
8731 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008732 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00008735- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8736 object to complex using its __complex__() method before falling back
8737 to the __float__() method. Therefore, the functions in the cmath
8738 module now can operate on objects that define a __complex__()
8739 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008761 its argument, if it exists. If not, it will work like before. This
8762 allows customizing the output of dir() in the presence of a
8763 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00008775- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00008845- Bug #1545497: when given an explicit base, int() did ignore NULs
8846 embedded in the string to convert.
8847
Georg Brandl846f73a2006-10-08 07:11:54 +00008848- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008878- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008896 generator expressions (x for x, in ... ) works again. Fixing this
8897 problem required changing the .pyc magic number. This means that
8898 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009806 time so that opening a database previously created with the DB_DUP
9807 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9808 opens. Specifically: dictionary assignment to a DB object will
9809 replace all values for a given key when the database allows
9810 duplicate values. DB users should use DB.put(k, v) when they want
9811 to store duplicates; not DB[k] = v.

9818 characters with ASCII value less than 32. Also, it correctly quotes
9819 dots only if they occur on a single line, as opposed to the previous
9820 behavior of quoting dots if they are the second character of any
9821 line.
