Ned Deily18fae3f2013-01-31 01:24:55 -08001536- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1537 In particular, fix extension module build failures when trying to use
1538 32-bit-only installer Pythons on systems with Xcode 4 (currently
1539 OS X 10.8, 10.7, and optionally 10.6).
1540 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1541 * Since Xcode 4 removes ppc support, extension module builds now
1542 check for ppc compiler support and by default remove ppc and
1543 ppc64 archs when they are not available.
1544 * Extension module builds now revert to using system installed
1545 headers and libs (/usr and /System/Library) if the SDK used
1546 to build the interpreter is not installed or has moved.
1547 * Try to avoid building extension modules with deprecated
1548 and problematic Apple llvm-gcc compiler. If original compiler
1549 is not available, use clang instead by default.

1981 Distutils-based packages with C extension modules may fail because
1982 Apple has removed gcc-4.2, the version used to build python.org
1983 64-bit/32-bit Pythons. If the user does not explicitly override
1984 the default C compiler by setting the CC environment variable,
1985 Distutils will now attempt to compile extension modules with clang
1986 if gcc-4.2 is required but not found. Also as a convenience, if
1987 the user does explicitly set CC, substitute its value as the default
1988 compiler in the Distutils LDSHARED configuration variable for OS X.
1989 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1990 SDK, neither of which are available in Xcode 4. This change does not
1991 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002241- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2242 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2243 interpreter process. This could cause failures in non-Distutils subprocesses
2244 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002245 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002246 deployment target only in the environment of each build subprocess. It is
2247 still possible to globally override the default by setting
2248 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2249 greater or equal to the default value, the value with which the interpreter
2250 was built.

2280 the ticker doesn't have to wind down to zero from the old starting point
2281 before the new interval takes effect. And if the user increases the
2282 interval, it makes sure the new limit takes effect right away rather have an
2283 early task switch before recognizing the new interval.

3264 This prevents user-created self-referencing ordered dictionaries from
3265 becoming permanently uncollectable GC garbage. The downside is that
3266 removing __del__ means that the internal doubly-linked list has to wait for
3267 GC collection rather than freeing memory immediately when the refcnt drops
3268 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003726- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3727 start byte and the continuation byte(s) are now considered invalid, instead
3728 of the number of bytes specified by the start byte.
3729 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3730 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3742 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4111
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004112- Issue #7301: Add environment variable $PYTHONWARNINGS.
4113
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004114- Issue #8329: Don't return the same lists from select.select when no fds are
4115 changed.
4116
Georg Brandlfee0f442010-05-22 21:26:21 +00004117- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004118 on 64-bit machines. The shift count for either left or right shift is
4119 permitted to be up to sys.maxsize.
4120
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004121- Ensure that tokenization of identifiers is not affected by locale.

4126
Georg Brandlfee0f442010-05-22 21:26:21 +00004127- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4128 with a non-empty format string. This is an effort to future-proof user
4129 code. If a derived class does not currently implement __format__ but later
4130 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004131 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004132 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004133
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004134- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004147- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004148 (SIGINT). If an error occurs while importing the site module, the error is

4164
Georg Brandlfee0f442010-05-22 21:26:21 +00004165- Issue #8257: The Decimal construct now accepts a float instance directly,
4166 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004167
4168 >>> Decimal(1.1)
4169 Decimal('1.100000000000000088817841970012523233890533447265625')
4170
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004171- collections.Counter() now supports a subtract() method.
4172
Georg Brandlfee0f442010-05-22 21:26:21 +00004173- The functools module now has a total_ordering() class decorator to simplify
4174 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004182- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4183 InvalidOperation instead of returning False. (Comparisons involving a quiet
4184 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4185 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004186
Georg Brandlfee0f442010-05-22 21:26:21 +00004187- Issue #2531: Comparison operations between floats and Decimal instances now
4188 return a result based on the numeric values of the operands; previously they
4189 returned an arbitrary result based on the relative ordering of id(float) and
4190 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004191
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004192- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004193 argument `-` which tells it to read files to compile from stdin. Each line is
4194 read on demand and the named file is compiled immediately. (Original patch by
4195 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004200- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4201 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004202 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004203
Georg Brandlfee0f442010-05-22 21:26:21 +00004204- Comparisons using one of <, <=, >, >= between a complex instance and a
4205 Fractions instance now raise TypeError instead of returning True/False. This
4206 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4207 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004569- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4570 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4571 returning NULL. The macro now returns a statically allocated empty string
4572 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004625 file position when calling `truncate()`. It would previously change the file
4626 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004627 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4630 class used to represent files stored inside an archive. The new
4631 implementation is significantly faster and can be wrapped in a
4632 ``io.BufferedReader`` object for more speedups. It also solves an issue
4633 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004644- Issue #7748: Since unicode values are supported for some metadata options in
4645 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4646 encoded string for them. This ensures that the upload and register commands
4647 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00004730- Issue #5080: A number of functions and methods previously produced a

4732 These functions and methods now raise TypeError instead. The majority of the
4733 effects of this change are in the extension modules, but some core functions
4734 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4735 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004917- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4918 decimal string that's guaranteed to round back to x under correct rounding
4919 (with round-half-to-even rounding mode). Previously it gave a string based on
4920 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4921 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4922 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004923
Georg Brandlba83f822010-03-14 09:50:54 +00004924- Issue #7117: On almost all platforms: float-to-string and string-to-float
4925 conversions within Python are now correctly rounded. Places these conversions
4926 occur include: str for floats and complex numbers; the float and complex
4927 constructors; old-style and new-style numeric formatting; serialization and
4928 deserialization of floats and complex numbers using marshal, pickle and json;
4929 parsing of float and imaginary literals in Python code; Decimal-to-float
4930 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004931
Georg Brandlba83f822010-03-14 09:50:54 +00004932 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4933 providing correctly-rounded strtod and dtoa C functions. This code is
4934 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4935 the C compiler. There may be a small number of platforms on which correct
4936 operation of this code cannot be guaranteed, so the code is not used: notably,
4937 this applies to platforms where the C double format is not IEEE 754 binary64,
4938 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4939 and Python's configure script is unable to determine how to change the FPU
4940 precision. On these platforms conversions use the platform strtod and dtoa,
4941 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004943- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4944 uses the correctly-rounded string <-> float conversions described above (when
4945 available), and so produces correctly rounded results that will display nicely
4946 under the float repr. There are two related small changes: (1) round now
4947 accepts any class with an ``__index__()`` method for its second argument (but
4948 no longer accepts floats for the second argument), and (2) an excessively
4949 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4950 raises an exception.

5329 this code path is really executed because I cannot move to such directory on

5356 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006736- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6737 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6738 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6739 ``printf`` function, whereas PyString_FromFormat has an independent
6740 implementation and uses "%zd" on all platforms for size_t values.
6741 This makes a difference on win64, where ``printf`` needs "%Id" to display
6742 64bit values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006837 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6838 for catch_warnings() also led to an improvement in the raising of a
6839 DeprecationWarning related to warnings.warn_explicit().
6840
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006841- The deprecation warnings for the old camelCase threading API were removed.

6863
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006864- Issue #2975: When compiling several extension modules with Visual Studio 2008
6865 from the same python interpreter, some environment variables would grow
6866 without limit.
6867
Benjamin Peterson37346b22008-08-23 20:27:43 +00006868- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6869 exploitation of poor argument checking.
6870
Gerhard Häringef2276b2008-09-12 13:54:06 +00006871- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006905What's New in Python 2.6 beta 3?
6906================================
6907
Barry Warsaw07a4a382008-08-21 01:15:08 +00006908*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006909
6910Core and Builtins
6911-----------------
6912
Guido van Rossumf8402962008-08-20 15:01:50 +00006913- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6914 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6915 extensions do not automatically benefit from the class attribute
6916 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6917 to their tp_flags field if they care. This is a backwards
6918 compatibility feature; in 3.0, all types will use the cache by
6919 default.
6920
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006921- Keyword arguments can now follow starred arguments. (``f(a, *args,
6922 keyword=23)`` is now valid syntax.)
6923
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006924- ctypes function pointers that are COM methods have a boolean True
6925 value again.
6926
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006927- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6928 by denying s# to parse objects that have a releasebuffer procedure,
6929 and introducing s*.
6930
Georg Brandl1e13ea92008-08-11 09:07:59 +00006931- Issue #3537: Fix an assertion failure when an empty but presized dict
6932 object was stored in the freelist.
6933
Mark Dickinsonb6467572008-08-04 21:30:09 +00006934- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6935 ValueError consistently across platforms.
6936
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006937- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6938 (64bit Unix, for example), unichr() would truncate its argument and return
6939 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6940
Neal Norwitze7d8be82008-07-31 17:17:14 +00006941- Apply security patches from Apple.
6942
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006943- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6944 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6945
Antoine Pitrou92f82162008-07-25 22:22:08 +00006946- Issue #1819: function calls with several named parameters are now on
6947 average 35% faster (as measured by pybench).
6948
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006949- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6950 the python debugger steps into a class statement: the free variables (local
6951 variables defined in an outer scope) would be deleted from the outer scope.
6952
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006953- Issue #2620: Overflow checking when allocating or reallocating memory
6954 was not always being done properly in some python types and extension
6955 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6956 all been updated to perform better checks and places in the code that
6957 would previously leak memory on the error path when such an allocation
6958 failed have been fixed.
6959

6964
Benjamin Petersone977ad42008-08-20 01:42:01 +00006965- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6966 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6967
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006968- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6969 version reported by these tools does not necessarily follow the python
6970 version numbering scheme, so the module is less strict when parsing it.
6971
Nick Coghlanf70385a2008-08-18 12:42:46 +00006972- Issue #2235: Added Py3k warnings for types which will become unhashable
6973 under the stricter __hash__ inheritance rules in 3.0. Several types
6974 which did not meet the rules for hash invariants and were already
6975 unhashable in 3.0 have now been explicitly flagged as unhashable in
6976 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6977 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6978
Brett Cannon88f801d2008-08-18 00:46:22 +00006979- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6980 imported into the module but exposed as part of the module's API.
6981
Brett Cannon7b96f072008-08-18 00:41:11 +00006982- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6983

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006986- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6987
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006988- Issue #3575: Incremental decoder's decode function now takes bytearray
6989 by using 's*' instead of 't#'.
6990
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006991- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006992 fails unicode conversion on 2nd parameter. (windows only)
6993
Georg Brandl222e2082010-08-01 22:27:39 +00006994- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006995 in a redirect.
6996

Brett Cannon721b1452008-08-16 22:00:27 +00006998 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006999
Facundo Batistaeb90b782008-08-16 14:44:07 +00007000- Issue #2776: fixed small issue when handling an URL with double slash
7001 after a 302 response in the case of not going through a proxy.
7002
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007003- Issue #2676: in the email package, content-type parsing was hanging on
7004 pathological input because of quadratic or exponential behaviour of a
7005 regular expression.
7006
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007007- Issue #3476: binary buffered reading through the new "io" library is now
7008 thread-safe.
7009
Brett Cannonbf3157b2008-08-14 05:00:03 +00007010- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7011 since mimetools itself is deprecated. Because modules are cached, all
7012 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7013
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007014- Issue #3134: shutil referenced undefined WindowsError symbol.
7015
Robert Schuppenies14646332008-08-10 11:01:53 +00007016- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7017 menu entries were not deleted.
7018
Brett Cannon83e81842008-08-09 23:30:55 +00007019- Copied the implementation of reduce() to _functools.reduce() to have a
7020 version that did not raise a DeprecationWarning under -3.
7021
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007022- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7023 a MemoryError rather than silently stop the iteration.
7024
Guido van Rossum59ce9012008-08-09 14:55:34 +00007025- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7026 to _sre.compile() will now be rejected. This should not affect anybody
7027 since the re.compile() function never generates invalid re-bytecode.
7028
Skip Montanaroa032bf42008-08-08 22:52:51 +00007029- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7030 upon first access it can be automatically initialized from the csv file if
7031 it wasn't initialized during instantiation.
7032
Brett Cannon3aa2a492008-08-06 22:28:09 +00007033- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7034 the reload() built-in has been removed.
7035
Brett Cannon7e30b672008-08-04 21:52:25 +00007036- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007037 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007048 asking for a specific length. This problem only affected files opened
7049 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007050

7075 file name rather than a ZipInfo instance, so files are extracted with
7076 mode 0600 rather than 000 under Unix.
7077
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007078- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

7095 regarding lack of coverage of new-style classes have also been
7096 removed, since the coverage is now fairly reasonable.

Georg Brandl3e483f62008-07-16 22:57:41 +00007107- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7108 its methods now allow for items objects that can be converted to
7109 an integer using operator.index().
7110
Mark Dickinson64b7e502008-07-16 09:40:03 +00007111- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7112 produced a ValueError instead of giving the correct float.
7113
Eric Smitha5fa5a22008-07-16 00:11:49 +00007114- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00007121- Issue #2235: __hash__ is once again inherited by default. To allow
7122 collections.Hashable to remain meaningful in the presence of the
7123 default hash implementation (object.__hash__), it is now possible
7124 to explicit block inheritance of hash by setting __hash__=None at
7125 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7126 level.
7127
Nick Coghlanb028f502008-07-13 14:52:36 +00007128- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7129 the parent module cannot be found while performing an absolute import.
7130 This means that an incorrectly defined __package__ attribute will
7131 now only prevent relative imports in that module rather than causing
7132 all imports from that module to fail.
7133
Nick Coghlan14ff9942008-07-08 14:21:42 +00007134- Issue #2517: Allow unicode messages in Exceptions again by correctly

7145
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007146- Issue #3004: Minor change to slice.indices(): the start and stop
7147 arguments are now treated identically, making the behaviour easier
7148 to describe and understand. For example, slice(None, -10,
7149 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7150 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7151 10, -1).

7194 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007195 wrong because the actual transmitted size could differ from the

7602 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007603 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007604
7605 This is controlled by the configure argument ``--with-universal-archs``:
7606
7607 - ``--with-universal-archs=all``: install 4-way universal
7608
7609 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7610
7611 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7612
7613 This option should be used in combination with ``--enable-universalsdk=``.
7614
7615 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7651 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007652
Christian Heimese74c8f22008-04-19 02:23:57 +00007653- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7654

7656 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007657

Gregory P. Smith671c5d92008-04-09 18:18:43 +00007663
Georg Brandl3ee81df2008-05-17 18:14:43 +00007664- Issue #1631171: Re-implement the 'warnings' module in C (the
7665 original Python code has been kept as backup). This will allow for
7666 using the 'warning's machinery in such places as the parser where
7667 use of pure Python code is not possible. Both the ``showarning()``
7668 and ``formatwarning()`` gain an optional 'line' argument which is
7669 not called by default for backwards-compatibility reasons. Setting
7670 ``warnings.showwarning()`` to an implementation that lacks support
7671 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007734- Issue #2550: The approach used by client/server code for obtaining
7735 ports to listen on in network-oriented tests has been refined in an
7736 effort to facilitate running multiple instances of the entire
7737 regression test suite in parallel without issue.
7738 test_support.bind_port() has been fixed such that it will always
7739 return a unique port -- which wasn't always the case with the
7740 previous implementation, especially if socket options had been set
7741 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7742 new implementation of bind_port() will actually raise an exception
7743 if it is passed an AF_INET/SOCK_STREAM socket with either the
7744 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7745 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7746 the socket it's been passed. This currently only applies to
7747 Windows. This option prevents any other sockets from binding to the
7748 host/port we've bound to, thus removing the possibility of the
7749 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7750 when a second SOCK_STREAM socket binds and accepts to a host/port
7751 that's already been bound by another socket. The optional preferred
7752 port parameter to bind_port() has been removed. Under no
7753 circumstances should tests be hard coding ports!
7754
7755 test_support.find_unused_port() has also been introduced, which will
7756 pass a temporary socket object to bind_port() in order to obtain an
7757 unused port. The temporary socket object is then closed and
7758 deleted, and the port is returned. This method should only be used
7759 for obtaining an unused port in order to pass to an external program
7760 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7761 a parameter to a server-oriented class that doesn't give you direct
7762 access to the underlying socket used.
7763
7764 Finally, test_support.HOST has been introduced, which should be used
7765 for the host argument of any relevant socket calls (i.e. bind and
7766 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007767
7768 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007770 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7771 test_asynchat and test_socket_ssl.
7772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773 It is now possible for multiple instances of the regression test
7774 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008053- Added the future_builtins module, which contains hex() and oct().
8054 These are the PEP 3127 version of these functions, designed to be
8055 compatible with the hex() and oct() builtins from Python 3.0. They
8056 differ slightly in their output formats from the existing, unchanged
8057 Python 2.6 builtins. The expected usage of the future_builtins
8058 module is:
8059 from future_builtins import hex, oct
8060
Eric Smith7ef40bf2008-02-20 23:34:22 +00008061- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8062 exponents for exponents with absolute value < 100. Follows C99
8063 standard. This is a change on Windows, which would use 3 digits.
8064 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8065 so that any alterations it does to the resulting string will be
8066 available in stringlib/formatter.h (for float.__format__).
8067
Eric Smith5a3c1352008-02-19 13:21:56 +00008068- Implemented PEP 3101, Advanced String Formatting. This adds a new
8069 builtin format(); a format() method for str and unicode; a
8070 __format__() method to object, str, unicode, int, long, float, and
8071 datetime; the class string.Formatter; and the C API
8072 PyObject_Format().
8073
Georg Brandl3ee81df2008-05-17 18:14:43 +00008074- Fixed several potential crashes, all caused by specially crafted
8075 __del__ methods exploiting objects in temporarily inconsistent
8076 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008077
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008078- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079 prevent a possible crash: an Abstract Base Class would try to access
8080 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008081

Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Clear all free lists during a gc.collect() of the highest generation
8086 in order to allow pymalloc to free more arenas. Python may give back
8087 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008088
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089- Issue #2045: Fix an infinite recursion triggered when printing a
8090 subclass of collections.defaultdict, if its default_factory is set
8091 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008092
Christian Heimesf75dbef2008-02-08 00:11:31 +00008093- Fixed a minor memory leak in dictobject.c. The content of the free
8094 list was not freed on interpreter shutdown.
8095
Georg Brandl21e99f42010-03-07 15:23:59 +00008096- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008097 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8100 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008101 to compact the internal free lists of pre-allocted ints and floats.
8102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8104 calls. Python expected the return type int but the fork familie
8105 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008106
Georg Brandl3ee81df2008-05-17 18:14:43 +00008107- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008119- Patch #1473257: generator objects gain a gi_code attribute. This is
8120 the same object as the func_code attribute of the function that
8121 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008122
Georg Brandl3ee81df2008-05-17 18:14:43 +00008123- Issue #1920: "while 0" statements were completely removed by the
8124 compiler, even in the presence of an "else" clause, which is
8125 supposed to be run when the condition is false. Now the compiler
8126 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008127
Guido van Rossumeead05f2008-01-24 18:21:02 +00008128- A few crashers fixed: weakref_in_del.py (issue #1377858);
8129 loosing_dict_ref.py (issue #1303614, test67.py);
8130 borrowed_ref_[34].py (not in tracker).
8131
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008132- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008133 suppressed while an extension is loaded by calling SetErrorMode in

8135
Georg Brandl3ee81df2008-05-17 18:14:43 +00008136- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008137 several extension methods and modules do not work without unicode
8138 support.
8139
Georg Brandl26543b12008-01-21 18:36:51 +00008140- Issue #1882: when compiling code from a string, encoding cookies in the
8141 second line of code were not always recognized correctly.
8142
Georg Brandl14404b62008-01-19 19:27:05 +00008143- Issue #1679: "0x" was taken as a valid integer literal.
8144
Georg Brandl6caad7d2008-01-26 14:19:22 +00008145- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008146 added.
8147
Christian Heimesc94e2b52008-01-14 04:13:37 +00008148- sys.float_info / PyFloat_GetInfo: The floating point information
8149 object was converted from a dict to a specialized structseq object.
8150
Georg Brandl3ee81df2008-05-17 18:14:43 +00008151- Patch #1816: Added sys.flags structseq. It exposes the status of
8152 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008153
Georg Brandl3ee81df2008-05-17 18:14:43 +00008154- Objects/structseq.c: Implemented new structseq representation. The
8155 patch makes structseqs (e.g. the return value of os.stat) more
8156 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008157
Georg Brandl3ee81df2008-05-17 18:14:43 +00008158- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008183- Compiler now generates simpler and faster code for dictionary
8184 literals. The oparg for BUILD_MAP now indicates an estimated
8185 dictionary size. There is a new opcode, STORE_MAP, for adding
8186 entries to the dictionary.

8216 file can now be directly executed by passing their name to the
8217 interpreter. The directory/zipfile is automatically inserted as the
8218 first entry in sys.path.

8229
Georg Brandl21e99f42010-03-07 15:23:59 +00008230- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008231 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8232 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- Issue #1686386: Tuple's tp_repr did not take into account the
8235 possibility of having a self-referential tuple, which is possible
8236 from C code. Nor did object's tp_str consider that a type's tp_str
8237 could do something that could lead to an inifinite recursion.
8238 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8239 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008240
Georg Brandl3ee81df2008-05-17 18:14:43 +00008241- Issue #1164: It was possible to trigger deadlock when using the
8242 'print' statement to write to a file since the GIL was not released
8243 as needed. Now PyObject_Print() does the right thing along with
8244 various tp_print implementations of the built-in types and those in
8245 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008246
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00008254- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255 PyObject_Call() never calling back out to Python code to trigger
8256 recursion depth updates/checks. Required the creation of a static
8257 RuntimeError instance in case normalizing an exception put the
8258 recursion check value past its limit. Fixes crashers
8259 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008274- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008275 __*__ attributes. (Some already existed, e.g., __doc__ and
8276 __name__.)

8282 calls.
8283
Collin Winter62903052007-05-18 23:11:24 +00008284- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285 "except E as target:". This is to provide forwards compatibility
8286 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008293- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008294 setting a plain string, ie don't expand to single letter identifiers.
8295
Raymond Hettinger13936692007-04-11 18:40:58 +00008296- Request #1191699: Slices can now be pickled.
8297
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008298- Request #1193128: str.translate() now allows a None argument for
8299 translations that only remove characters without re-mapping the
8300 remaining characters.
8301
Georg Brandl5cb76c12007-03-21 09:00:39 +00008302- Patch #1682205: a TypeError while unpacking an iterable is no longer

8306
Guido van Rossum143b5642007-03-23 04:58:42 +00008307- Bug #1683368: The object.__init__() and object.__new__() methods are
8308 now stricter in rejecting excess arguments. The only time when
8309 either allows excess arguments is when it is not overridden and the
8310 other one is. For backwards compatibility, when both are
8311 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008312 warning later). Also, type.__init__() insists on the same signature
8313 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008314
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8316 object to complex using its __complex__() method before falling back
8317 to the __float__() method. Therefore, the functions in the cmath
8318 module now can operate on objects that define a __complex__()
8319 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008321- Patch #1623563: allow __class__ assignment for classes with
8322 __slots__. The old and the new class are still required to have the
8323 same slot names.

8330 its type.

8336
Georg Brandl7b9c5552007-03-12 14:30:05 +00008337- Bug #1678647: write a newline after printing an exception in any
8338 case, even when converting the value to a string failed.
8339
Georg Brandl871f1bc2007-03-12 13:17:36 +00008340- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008341 its argument, if it exists. If not, it will work like before. This
8342 allows customizing the output of dir() in the presence of a
8343 __getattr__().

8347
Georg Brandl3ee81df2008-05-17 18:14:43 +00008348- Patch #1675981: remove unreachable code from ``type.__new__()``

8352 parthensized forms. This means complex(repr(x)) now works instead of
8353 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008354
Georg Brandlaa2321b2007-03-07 00:40:28 +00008355- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356 makes the filenames the warning module prints much more sensible
8357 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008370- Patch #1674228: when assigning a slice (old-style), check for the
8371 sq_ass_slice instead of the sq_slice slot.
8372
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373- When printing an unraisable error, don't print exceptions. before
8374 the name. This duplicates the behavior whening normally printing
8375 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00008458- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl92a6bae2007-03-13 17:43:32 +00008941- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008942 are set for invalid interpolation sequences that would lead to

8999 TestCase and TestSuite subclasses (not instances) are no longer
9000 accepted in TestSuite.addTest(). This should cause no

9002 -- the failure just occurred later, with a more cumbersome
9003 exception.

9281 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009282
Georg Brandl3ee81df2008-05-17 18:14:43 +00009283- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009284 that the SMTP.starttls() caller no longer needs to call ehlo()
9285 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286 does not claim to support starttls. Adds the
9287 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9368 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9369 silently miscode subclasses of those types. Now, it raises a
9370 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009371

Georg Brandl3ee81df2008-05-17 18:14:43 +00009386 time so that opening a database previously created with the DB_DUP
9387 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9388 opens. Specifically: dictionary assignment to a DB object will
9389 replace all values for a given key when the database allows
9390 duplicate values. DB users should use DB.put(k, v) when they want
9391 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009392

Georg Brandl3ee81df2008-05-17 18:14:43 +00009736- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9737 to ``PyTuple_SetItem``, it can be used to populate a brand new

9752 of w# format code incorrectly truncated the length to an int, even
9753 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9754 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009755

Georg Brandl3ee81df2008-05-17 18:14:43 +00009784- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9785 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009810- Removed the macfs module. It had been deprecated since Python 2.5.
9811 This lead to the deprecation of macostools.touched() as it relied
9812 solely on macfs and was a no-op under OS X.
