Ned Deily18fae3f2013-01-31 01:24:55 -0800746- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
747 In particular, fix extension module build failures when trying to use
748 32-bit-only installer Pythons on systems with Xcode 4 (currently
749 OS X 10.8, 10.7, and optionally 10.6).
750 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
751 * Since Xcode 4 removes ppc support, extension module builds now
752 check for ppc compiler support and by default remove ppc and
753 ppc64 archs when they are not available.
754 * Extension module builds now revert to using system installed
755 headers and libs (/usr and /System/Library) if the SDK used
756 to build the interpreter is not installed or has moved.
757 * Try to avoid building extension modules with deprecated
758 and problematic Apple llvm-gcc compiler. If original compiler
759 is not available, use clang instead by default.

1003 int.__pow__. These overflow checks were causing int.__pow__ to produce
1004 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001005 compiler optimizing the check away. Also fix similar overflow checks
1006 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1019 cleared by the garbage collector. This fixes a segfault when an instance
1020 and its type get caught in a reference cycle, and the instance's
1021 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01001075- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001076 has left two versions of customize_compiler, the original in
1077 distutils.sysconfig and another copy in distutils.ccompiler, with some
1078 parts of distutils calling one and others using the other.

1080 is the case in 3.x.
1081
Ned Deily0d0ea482012-02-10 12:59:06 +01001082- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1083 Distutils-based packages with C extension modules may fail because
1084 Apple has removed gcc-4.2, the version used to build python.org
1085 64-bit/32-bit Pythons. If the user does not explicitly override
1086 the default C compiler by setting the CC environment variable,
1087 Distutils will now attempt to compile extension modules with clang
1088 if gcc-4.2 is required but not found. Also as a convenience, if
1089 the user does explicitly set CC, substitute its value as the default
1090 compiler in the Distutils LDSHARED configuration variable for OS X.
1091 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1092 SDK, neither of which are available in Xcode 4. This change does not
1093 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001366- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1367 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1368 interpreter process. This could cause failures in non-Distutils subprocesses
1369 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001370 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001371 deployment target only in the environment of each build subprocess. It is
1372 still possible to globally override the default by setting
1373 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1374 greater or equal to the default value, the value with which the interpreter
1375 was built.

1405 the ticker doesn't have to wind down to zero from the old starting point
1406 before the new interval takes effect. And if the user increases the
1407 interval, it makes sure the new limit takes effect right away rather have an
1408 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002359- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2360 This prevents user-created self-referencing ordered dictionaries from
2361 becoming permanently uncollectable GC garbage. The downside is that
2362 removing __del__ means that the internal doubly-linked list has to wait for
2363 GC collection rather than freeing memory immediately when the refcnt drops
2364 to zero.

2394
R. David Murray7c4bf552010-08-25 01:45:57 +00002395- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2396 character years even if the message contains RFC822 two character years.

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002430- Issue #9550: a BufferedReader could issue an additional read when the
2431 original read request had been satisfied, which could block indefinitely
2432 when the underlying raw IO channel was e.g. a socket. Report and original
2433 patch by Jason V. Miller.

2839 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003184 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

3207-----------------
3208
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003209- Issue #7301: Add environment variable $PYTHONWARNINGS.
3210
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003211- Issue #8329: Don't return the same lists from select.select when no fds are
3212 changed.
3213
Georg Brandlfee0f442010-05-22 21:26:21 +00003214- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003215 on 64-bit machines. The shift count for either left or right shift is
3216 permitted to be up to sys.maxsize.
3217
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003218- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003220- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003221
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003222- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3223
Georg Brandlfee0f442010-05-22 21:26:21 +00003224- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3225 with a non-empty format string. This is an effort to future-proof user
3226 code. If a derived class does not currently implement __format__ but later
3227 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003228 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003229 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003230
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003231- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003244- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003245 (SIGINT). If an error occurs while importing the site module, the error is

3261
Georg Brandlfee0f442010-05-22 21:26:21 +00003262- Issue #8257: The Decimal construct now accepts a float instance directly,
3263 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003264
3265 >>> Decimal(1.1)
3266 Decimal('1.100000000000000088817841970012523233890533447265625')
3267
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003268- collections.Counter() now supports a subtract() method.
3269
Georg Brandlfee0f442010-05-22 21:26:21 +00003270- The functools module now has a total_ordering() class decorator to simplify
3271 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003272
Georg Brandlfee0f442010-05-22 21:26:21 +00003273- The functools module also adds cmp_to_key() as a tool to transition old-style
3274 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003275

Georg Brandlfee0f442010-05-22 21:26:21 +00003279- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3280 InvalidOperation instead of returning False. (Comparisons involving a quiet
3281 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3282 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003283
Georg Brandlfee0f442010-05-22 21:26:21 +00003284- Issue #2531: Comparison operations between floats and Decimal instances now
3285 return a result based on the numeric values of the operands; previously they
3286 returned an arbitrary result based on the relative ordering of id(float) and
3287 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003288
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003289- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003290 argument `-` which tells it to read files to compile from stdin. Each line is
3291 read on demand and the named file is compiled immediately. (Original patch by
3292 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003297- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3298 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003299 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003300
Georg Brandlfee0f442010-05-22 21:26:21 +00003301- Comparisons using one of <, <=, >, >= between a complex instance and a
3302 Fractions instance now raise TypeError instead of returning True/False. This
3303 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3304 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003359- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003360 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3361 log file to compute the next rollover time. If the log file does not exist,
3362 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00003372- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3373 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3374 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003403- Issue #8300: When passing a non-integer argument to struct.pack with any
3404 integer format code, struct.pack first attempts to convert the non-integer
3405 using its __index__ method. If that method is non-existent or raises
3406 TypeError it goes on to try the __int__ method, as described below.
3407
Georg Brandlba83f822010-03-14 09:50:54 +00003408- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3409 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3410 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003411 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3412 inconsistent: __int__ was used for some integer codes but not for others, and
3413 the set of integer codes for which it was used differed between native packing
3414 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003722 file position when calling `truncate()`. It would previously change the file
3723 position to the given argument, which goes against the tradition of

3730 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3743 encoded string for them. This ensures that the upload and register commands
3744 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004015- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4016 decimal string that's guaranteed to round back to x under correct rounding
4017 (with round-half-to-even rounding mode). Previously it gave a string based on
4018 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4019 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4020 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004021
Georg Brandlba83f822010-03-14 09:50:54 +00004022- Issue #7117: On almost all platforms: float-to-string and string-to-float
4023 conversions within Python are now correctly rounded. Places these conversions
4024 occur include: str for floats and complex numbers; the float and complex
4025 constructors; old-style and new-style numeric formatting; serialization and
4026 deserialization of floats and complex numbers using marshal, pickle and json;
4027 parsing of float and imaginary literals in Python code; Decimal-to-float
4028 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004029
Georg Brandlba83f822010-03-14 09:50:54 +00004030 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4031 providing correctly-rounded strtod and dtoa C functions. This code is
4032 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4033 the C compiler. There may be a small number of platforms on which correct
4034 operation of this code cannot be guaranteed, so the code is not used: notably,
4035 this applies to platforms where the C double format is not IEEE 754 binary64,
4036 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4037 and Python's configure script is unable to determine how to change the FPU
4038 precision. On these platforms conversions use the platform strtod and dtoa,
4039 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004041- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4042 uses the correctly-rounded string <-> float conversions described above (when
4043 available), and so produces correctly rounded results that will display nicely
4044 under the float repr. There are two related small changes: (1) round now
4045 accepts any class with an ``__index__()`` method for its second argument (but
4046 no longer accepts floats for the second argument), and (2) an excessively
4047 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4048 raises an exception.

4198 of 12. Previously, the behavior the same but with a default precision of 6.
4199 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004341- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4342 existing .py counterpart, override the co_filename attributes of all code
4343 objects if the original filename is obsolete (which can happen if the file has

4398
Georg Brandlba83f822010-03-14 09:50:54 +00004399- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4400 file objects with closefd=False. The file descriptor is still kept open but
4401 the file object behaves like a closed file. The ``FileIO`` object also got a
4402 new readonly attribute ``closefd``.

4421
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004422- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004425- On windows, ``os.chdir()`` given unicode was not working if
4426 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4427 this code path is really executed because I cannot move to such directory on
4428 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004430- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4431 element is temporarily replaced with an equivalent frozenset. But the
4432 eventual KeyError would always report the empty ``frozenset()`` as the missing
4433 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004453- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4454 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4455 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4456 of using the replace error handler in PyUnicode_DecodeUTF8().
4457
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004458- Issue #3739: The unicode-internal encoder now reports the number of characters

4460
Georg Brandlba83f822010-03-14 09:50:54 +00004461- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4463 gives improved memory leak detection when running under Valgrind, while taking
4464 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00004536 __main__.py file. This allows applications that run other Python scripts to
4537 support the same flexibility as the CPython command line itself.

5830
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005831- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5832 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5833 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5834 ``printf`` function, whereas PyString_FromFormat has an independent
5835 implementation and uses "%zd" on all platforms for size_t values.
5836 This makes a difference on win64, where ``printf`` needs "%Id" to display
5837 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005839- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5855
Vinay Sajip35e3b032008-09-01 14:33:59 +00005856- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005857 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5858 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5859 when given a tuple of classes as second argument, were looking up
5860 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5861 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005932 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5933 for catch_warnings() also led to an improvement in the raising of a
5934 DeprecationWarning related to warnings.warn_explicit().
5935
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005936- The deprecation warnings for the old camelCase threading API were removed.

5958
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005959- Issue #2975: When compiling several extension modules with Visual Studio 2008
5960 from the same python interpreter, some environment variables would grow
5961 without limit.
5962
Benjamin Peterson37346b22008-08-23 20:27:43 +00005963- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5964 exploitation of poor argument checking.
5965
Gerhard Häringef2276b2008-09-12 13:54:06 +00005966- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

5979 wrapper for warnings.catch_warnings() that makes it easier to check
5980 that expected warning messages are being reported.
5981

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006000What's New in Python 2.6 beta 3?
6001================================
6002
Barry Warsaw07a4a382008-08-21 01:15:08 +00006003*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006004
6005Core and Builtins
6006-----------------
6007
Guido van Rossumf8402962008-08-20 15:01:50 +00006008- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6009 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6010 extensions do not automatically benefit from the class attribute
6011 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6012 to their tp_flags field if they care. This is a backwards
6013 compatibility feature; in 3.0, all types will use the cache by
6014 default.
6015
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006016- Keyword arguments can now follow starred arguments. (``f(a, *args,
6017 keyword=23)`` is now valid syntax.)
6018
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006019- ctypes function pointers that are COM methods have a boolean True
6020 value again.
6021
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006022- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6023 by denying s# to parse objects that have a releasebuffer procedure,
6024 and introducing s*.
6025
Georg Brandl1e13ea92008-08-11 09:07:59 +00006026- Issue #3537: Fix an assertion failure when an empty but presized dict
6027 object was stored in the freelist.
6028
Mark Dickinsonb6467572008-08-04 21:30:09 +00006029- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6030 ValueError consistently across platforms.
6031
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006032- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6033 (64bit Unix, for example), unichr() would truncate its argument and return
6034 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6035
Neal Norwitze7d8be82008-07-31 17:17:14 +00006036- Apply security patches from Apple.
6037
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006038- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6039 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6040
Antoine Pitrou92f82162008-07-25 22:22:08 +00006041- Issue #1819: function calls with several named parameters are now on
6042 average 35% faster (as measured by pybench).
6043
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006044- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6045 the python debugger steps into a class statement: the free variables (local
6046 variables defined in an outer scope) would be deleted from the outer scope.
6047
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006048- Issue #2620: Overflow checking when allocating or reallocating memory
6049 was not always being done properly in some python types and extension
6050 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6051 all been updated to perform better checks and places in the code that
6052 would previously leak memory on the error path when such an allocation
6053 failed have been fixed.
6054
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006055Library
6056-------
6057
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006058- Issue #3612: Added some missing basic types in ctypes.wintypes.
6059
Benjamin Petersone977ad42008-08-20 01:42:01 +00006060- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6061 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6062
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006063- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6064 version reported by these tools does not necessarily follow the python
6065 version numbering scheme, so the module is less strict when parsing it.
6066
Nick Coghlanf70385a2008-08-18 12:42:46 +00006067- Issue #2235: Added Py3k warnings for types which will become unhashable
6068 under the stricter __hash__ inheritance rules in 3.0. Several types
6069 which did not meet the rules for hash invariants and were already
6070 unhashable in 3.0 have now been explicitly flagged as unhashable in
6071 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6072 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6073
Brett Cannon88f801d2008-08-18 00:46:22 +00006074- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6075 imported into the module but exposed as part of the module's API.
6076
Brett Cannon7b96f072008-08-18 00:41:11 +00006077- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6078
Brett Cannon46225e72008-08-18 00:36:52 +00006079- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006081- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6082
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006083- Issue #3575: Incremental decoder's decode function now takes bytearray
6084 by using 's*' instead of 't#'.
6085
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006086- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006087 fails unicode conversion on 2nd parameter. (windows only)
6088
Georg Brandl222e2082010-08-01 22:27:39 +00006089- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006090 in a redirect.
6091
Brett Cannonabe423e2008-08-16 21:47:07 +00006092- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006093 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006094
Facundo Batistaeb90b782008-08-16 14:44:07 +00006095- Issue #2776: fixed small issue when handling an URL with double slash
6096 after a 302 response in the case of not going through a proxy.
6097
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006098- Issue #2676: in the email package, content-type parsing was hanging on
6099 pathological input because of quadratic or exponential behaviour of a
6100 regular expression.
6101
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006102- Issue #3476: binary buffered reading through the new "io" library is now
6103 thread-safe.
6104
Brett Cannonbf3157b2008-08-14 05:00:03 +00006105- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6106 since mimetools itself is deprecated. Because modules are cached, all
6107 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6108
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006109- Issue #3134: shutil referenced undefined WindowsError symbol.
6110
Robert Schuppenies14646332008-08-10 11:01:53 +00006111- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6112 menu entries were not deleted.
6113
Brett Cannon83e81842008-08-09 23:30:55 +00006114- Copied the implementation of reduce() to _functools.reduce() to have a
6115 version that did not raise a DeprecationWarning under -3.
6116
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006117- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6118 a MemoryError rather than silently stop the iteration.
6119
Guido van Rossum59ce9012008-08-09 14:55:34 +00006120- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6121 to _sre.compile() will now be rejected. This should not affect anybody
6122 since the re.compile() function never generates invalid re-bytecode.
6123
Skip Montanaroa032bf42008-08-08 22:52:51 +00006124- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6125 upon first access it can be automatically initialized from the csv file if
6126 it wasn't initialized during instantiation.
6127
Brett Cannon3aa2a492008-08-06 22:28:09 +00006128- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6129 the reload() built-in has been removed.
6130
Brett Cannon7e30b672008-08-04 21:52:25 +00006131- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006132 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006143 asking for a specific length. This problem only affected files opened
6144 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006145

6170 file name rather than a ZipInfo instance, so files are extracted with
6171 mode 0600 rather than 000 under Unix.
6172
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006173- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6174 argument in python 2.5, this broke code that subclassed Popen to include its
6175 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6190 regarding lack of coverage of new-style classes have also been
6191 removed, since the coverage is now fairly reasonable.

6201
Georg Brandl3e483f62008-07-16 22:57:41 +00006202- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6203 its methods now allow for items objects that can be converted to
6204 an integer using operator.index().
6205
Mark Dickinson64b7e502008-07-16 09:40:03 +00006206- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6207 produced a ValueError instead of giving the correct float.
6208
Eric Smitha5fa5a22008-07-16 00:11:49 +00006209- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00006216- Issue #2235: __hash__ is once again inherited by default. To allow
6217 collections.Hashable to remain meaningful in the presence of the
6218 default hash implementation (object.__hash__), it is now possible
6219 to explicit block inheritance of hash by setting __hash__=None at
6220 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6221 level.
6222
Nick Coghlanb028f502008-07-13 14:52:36 +00006223- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6224 the parent module cannot be found while performing an absolute import.
6225 This means that an incorrectly defined __package__ attribute will
6226 now only prevent relative imports in that module rather than causing
6227 all imports from that module to fail.
6228
Nick Coghlan14ff9942008-07-08 14:21:42 +00006229- Issue #2517: Allow unicode messages in Exceptions again by correctly

6240
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006241- Issue #3004: Minor change to slice.indices(): the start and stop
6242 arguments are now treated identically, making the behaviour easier
6243 to describe and understand. For example, slice(None, -10,
6244 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6245 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6246 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006248- Issue #3219: Calling a function with repeated keyword arguments,
6249 f(a=2, a=23), would not cause a syntax error. This was a regression
6250 from 2.4 caused by the switch to the new compiler.

6289 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006290 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00006700 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006701
6702 This is controlled by the configure argument ``--with-universal-archs``:
6703

6705
6706 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6707
6708 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

6749 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006750
Christian Heimese74c8f22008-04-19 02:23:57 +00006751- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006762- Issue #1631171: Re-implement the 'warnings' module in C (the
6763 original Python code has been kept as backup). This will allow for
6764 using the 'warning's machinery in such places as the parser where
6765 use of pure Python code is not possible. Both the ``showarning()``
6766 and ``formatwarning()`` gain an optional 'line' argument which is
6767 not called by default for backwards-compatibility reasons. Setting
6768 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00006832- Issue #2550: The approach used by client/server code for obtaining
6833 ports to listen on in network-oriented tests has been refined in an
6834 effort to facilitate running multiple instances of the entire
6835 regression test suite in parallel without issue.
6836 test_support.bind_port() has been fixed such that it will always
6837 return a unique port -- which wasn't always the case with the
6838 previous implementation, especially if socket options had been set
6839 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6840 new implementation of bind_port() will actually raise an exception
6841 if it is passed an AF_INET/SOCK_STREAM socket with either the
6842 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6843 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6844 the socket it's been passed. This currently only applies to
6845 Windows. This option prevents any other sockets from binding to the
6846 host/port we've bound to, thus removing the possibility of the
6847 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6848 when a second SOCK_STREAM socket binds and accepts to a host/port
6849 that's already been bound by another socket. The optional preferred
6850 port parameter to bind_port() has been removed. Under no
6851 circumstances should tests be hard coding ports!
6852
6853 test_support.find_unused_port() has also been introduced, which will
6854 pass a temporary socket object to bind_port() in order to obtain an
6855 unused port. The temporary socket object is then closed and
6856 deleted, and the port is returned. This method should only be used
6857 for obtaining an unused port in order to pass to an external program
6858 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6859 a parameter to a server-oriented class that doesn't give you direct
6860 access to the underlying socket used.
6861
6862 Finally, test_support.HOST has been introduced, which should be used
6863 for the host argument of any relevant socket calls (i.e. bind and
6864 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006865
6866 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006867 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006868 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6869 test_asynchat and test_socket_ssl.
6870
Georg Brandl3ee81df2008-05-17 18:14:43 +00006871 It is now possible for multiple instances of the regression test
6872 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007038- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
7039 values on 32-bit vs. 64-bit python interpreters. Both were correct,
7040 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00007151- Added the future_builtins module, which contains hex() and oct().
7152 These are the PEP 3127 version of these functions, designed to be
7153 compatible with the hex() and oct() builtins from Python 3.0. They
7154 differ slightly in their output formats from the existing, unchanged
7155 Python 2.6 builtins. The expected usage of the future_builtins
7156 module is:
7157 from future_builtins import hex, oct
7158
Eric Smith7ef40bf2008-02-20 23:34:22 +00007159- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7160 exponents for exponents with absolute value < 100. Follows C99
7161 standard. This is a change on Windows, which would use 3 digits.
7162 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7163 so that any alterations it does to the resulting string will be
7164 available in stringlib/formatter.h (for float.__format__).
7165
Eric Smith5a3c1352008-02-19 13:21:56 +00007166- Implemented PEP 3101, Advanced String Formatting. This adds a new
7167 builtin format(); a format() method for str and unicode; a
7168 __format__() method to object, str, unicode, int, long, float, and
7169 datetime; the class string.Formatter; and the C API
7170 PyObject_Format().
7171
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Fixed several potential crashes, all caused by specially crafted
7173 __del__ methods exploiting objects in temporarily inconsistent
7174 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007175
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007176- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007177 prevent a possible crash: an Abstract Base Class would try to access
7178 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007179
Georg Brandl3ee81df2008-05-17 18:14:43 +00007180- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00007183- Clear all free lists during a gc.collect() of the highest generation
7184 in order to allow pymalloc to free more arenas. Python may give back
7185 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007186
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187- Issue #2045: Fix an infinite recursion triggered when printing a
7188 subclass of collections.defaultdict, if its default_factory is set
7189 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007190
Christian Heimesf75dbef2008-02-08 00:11:31 +00007191- Fixed a minor memory leak in dictobject.c. The content of the free
7192 list was not freed on interpreter shutdown.
7193
Georg Brandl21e99f42010-03-07 15:23:59 +00007194- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007195 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7198 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007199 to compact the internal free lists of pre-allocted ints and floats.
7200
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7202 calls. Python expected the return type int but the fork familie
7203 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007204
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7206 appear in the same code unit.

7215 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- Patch #1473257: generator objects gain a gi_code attribute. This is
7218 the same object as the func_code attribute of the function that
7219 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007220
Georg Brandl3ee81df2008-05-17 18:14:43 +00007221- Issue #1920: "while 0" statements were completely removed by the
7222 compiler, even in the presence of an "else" clause, which is
7223 supposed to be run when the condition is false. Now the compiler
7224 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007225
Guido van Rossumeead05f2008-01-24 18:21:02 +00007226- A few crashers fixed: weakref_in_del.py (issue #1377858);
7227 loosing_dict_ref.py (issue #1303614, test67.py);
7228 borrowed_ref_[34].py (not in tracker).
7229
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007230- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007231 suppressed while an extension is loaded by calling SetErrorMode in
7232 dynload_win.c. The error is still reported properly.
7233
Georg Brandl3ee81df2008-05-17 18:14:43 +00007234- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007235 several extension methods and modules do not work without unicode
7236 support.
7237
Georg Brandl26543b12008-01-21 18:36:51 +00007238- Issue #1882: when compiling code from a string, encoding cookies in the
7239 second line of code were not always recognized correctly.
7240
Georg Brandl14404b62008-01-19 19:27:05 +00007241- Issue #1679: "0x" was taken as a valid integer literal.
7242
Georg Brandl6caad7d2008-01-26 14:19:22 +00007243- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007244 added.
7245
Christian Heimesc94e2b52008-01-14 04:13:37 +00007246- sys.float_info / PyFloat_GetInfo: The floating point information
7247 object was converted from a dict to a specialized structseq object.
7248
Georg Brandl3ee81df2008-05-17 18:14:43 +00007249- Patch #1816: Added sys.flags structseq. It exposes the status of
7250 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007251
Georg Brandl3ee81df2008-05-17 18:14:43 +00007252- Objects/structseq.c: Implemented new structseq representation. The
7253 patch makes structseqs (e.g. the return value of os.stat) more
7254 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007255
Georg Brandl3ee81df2008-05-17 18:14:43 +00007256- Patch #1700288: added a type attribute cache that caches method

7265 envvar and sys.dont_write_bytecode attribute. All these can be set
7266 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268- Improve some exception messages when Windows fails to load an
7269 extension module. Now we get for example '%1 is not a valid Win32
7270 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007271

Georg Brandl3ee81df2008-05-17 18:14:43 +00007281- Compiler now generates simpler and faster code for dictionary
7282 literals. The oparg for BUILD_MAP now indicates an estimated
7283 dictionary size. There is a new opcode, STORE_MAP, for adding
7284 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007329 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7330 automatically shifts from ints to longs.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007332- Issue #1686386: Tuple's tp_repr did not take into account the
7333 possibility of having a self-referential tuple, which is possible
7334 from C code. Nor did object's tp_str consider that a type's tp_str
7335 could do something that could lead to an inifinite recursion.
7336 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7337 issues.

7340 'print' statement to write to a file since the GIL was not released
7341 as needed. Now PyObject_Print() does the right thing along with
7342 various tp_print implementations of the built-in types and those in
7343 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007353 PyObject_Call() never calling back out to Python code to trigger
7354 recursion depth updates/checks. Required the creation of a static

7404
Guido van Rossum143b5642007-03-23 04:58:42 +00007405- Bug #1683368: The object.__init__() and object.__new__() methods are
7406 now stricter in rejecting excess arguments. The only time when
7407 either allows excess arguments is when it is not overridden and the
7408 other one is. For backwards compatibility, when both are
7409 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007410 warning later). Also, type.__init__() insists on the same signature
7411 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007413- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7414 object to complex using its __complex__() method before falling back
7415 to the __float__() method. Therefore, the functions in the cmath
7416 module now can operate on objects that define a __complex__()
7417 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007435- Bug #1678647: write a newline after printing an exception in any
7436 case, even when converting the value to a string failed.
7437
Georg Brandl871f1bc2007-03-12 13:17:36 +00007438- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007439 its argument, if it exists. If not, it will work like before. This
7440 allows customizing the output of dir() in the presence of a
7441 __getattr__().

7451 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007452
Georg Brandlaa2321b2007-03-07 00:40:28 +00007453- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454 makes the filenames the warning module prints much more sensible
7455 when a PYTHONSTARTUP file is used.

7469 sq_ass_slice instead of the sq_slice slot.
7470
Georg Brandl3ee81df2008-05-17 18:14:43 +00007471- When printing an unraisable error, don't print exceptions. before

8039
Georg Brandl92a6bae2007-03-13 17:43:32 +00008040- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041 are set for invalid interpolation sequences that would lead to
8042 errors on reading back those values.

8098 TestCase and TestSuite subclasses (not instances) are no longer
8099 accepted in TestSuite.addTest(). This should cause no

8101 -- the failure just occurred later, with a more cumbersome
8102 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008389 that the SMTP.starttls() caller no longer needs to call ehlo()
8390 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008391 does not claim to support starttls. Adds the
8392 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008491 time so that opening a database previously created with the DB_DUP
8492 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8493 opens. Specifically: dictionary assignment to a DB object will

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008775- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008776 periodic threadstate and signal checking in tight loops. By
8777 default, this option is turned-off. It should only be enabled in
8778 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008836- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8837 to ``PyTuple_SetItem``, it can be used to populate a brand new

8852 of w# format code incorrectly truncated the length to an int, even
8853 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8854 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008884- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8885 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
