1039
1040- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1041 and later systems as is currently done for Python 3.x installers.
1042 For 2.7.7 only, we will provide three installers:
1043 the legacy deprecated 10.3+ 32-bit-only format;
1044 the newer 10.5+ 32-bit-only format;
1045 and the unchanged 10.6+ 64-/32-bit format.
1046 Although binary installers will no longer be available from
1047 python.org as of 2.7.8, it will still be possible to build from
1048 source on 10.3.9 and 10.4 systems if necessary.
1049 See Mac/BuildScript/README.txt for more information.

2413 some more recent platforms.
2414
Gregory P. Smitha06ad5b2013-02-01 13:07:27 -08002415- Issue #12268: The io module file object write methods no longer abort early
2416 when a write system calls is interrupted (EINTR).
Gregory P. Smitha998ad02013-02-01 13:02:59 -08002417
Gregory P. Smith0d68ab32012-11-27 10:19:29 -08002418- Fix the leak of a dict in the time module when used in an embedded

Gregory P. Smith99716162012-10-12 13:02:06 -07002421- Issue #12268: File readline, readlines and read or readall methods
2422 no longer lose data when an underlying read system call is interrupted
2423 within an io module object. IOError is no longer raised due to a read
2424 system call returning EINTR from within these methods.

2427 method doesn't require an argument again.
2428
Ned Deily18fae3f2013-01-31 01:24:55 -08002429- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2430 In particular, fix extension module build failures when trying to use
2431 32-bit-only installer Pythons on systems with Xcode 4 (currently
2432 OS X 10.8, 10.7, and optionally 10.6).
2433 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2434 * Since Xcode 4 removes ppc support, extension module builds now
2435 check for ppc compiler support and by default remove ppc and
2436 ppc64 archs when they are not available.
2437 * Extension module builds now revert to using system installed
2438 headers and libs (/usr and /System/Library) if the SDK used
2439 to build the interpreter is not installed or has moved.
2440 * Try to avoid building extension modules with deprecated
2441 and problematic Apple llvm-gcc compiler. If original compiler
2442 is not available, use clang instead by default.

2810 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002886- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2887 Distutils-based packages with C extension modules may fail because
2888 Apple has removed gcc-4.2, the version used to build python.org
2889 64-bit/32-bit Pythons. If the user does not explicitly override
2890 the default C compiler by setting the CC environment variable,
2891 Distutils will now attempt to compile extension modules with clang
2892 if gcc-4.2 is required but not found. Also as a convenience, if
2893 the user does explicitly set CC, substitute its value as the default
2894 compiler in the Distutils LDSHARED configuration variable for OS X.
2895 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2896 SDK, neither of which are available in Xcode 4. This change does not
2897 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003147- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3148 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3149 interpreter process. This could cause failures in non-Distutils subprocesses
3150 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003151 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003152 deployment target only in the environment of each build subprocess. It is
3153 still possible to globally override the default by setting
3154 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3155 greater or equal to the default value, the value with which the interpreter
3156 was built.

3183
Barry Warsawc5643282011-07-19 17:06:30 -04003184- sys.setcheckinterval() now updates the current ticker count as well as
3185 updating the check interval, so if the user decreases the check interval,
3186 the ticker doesn't have to wind down to zero from the old starting point
3187 before the new interval takes effect. And if the user increases the
3188 interval, it makes sure the new limit takes effect right away rather have an
3189 early task switch before recognizing the new interval.

4170 handles non-blocking readinto() returning None correctly.
4171
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00004172- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
4173 SSLSocket.sendto() to match the corresponding socket methods. Also,
4174 fix various SSLSocket methods to raise socket.error rather than an
4175 unhelpful TypeError when called on an unconnected socket. Original patch
4176 by Andrew Bennetts.

4185
Raymond Hettinger20397532010-09-12 02:11:45 +00004186- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4187 This prevents user-created self-referencing ordered dictionaries from
4188 becoming permanently uncollectable GC garbage. The downside is that
4189 removing __del__ means that the internal doubly-linked list has to wait for
4190 GC collection rather than freeing memory immediately when the refcnt drops
4191 to zero.
4192
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004193- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

4196
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004197- Issue #9792: In case of connection failure, socket.create_connection()
4198 would swallow the exception and raise a new one, making it impossible
4199 to fetch the original errno, or to filter timeout errors. Now the
4200 original error is re-raised.
4201
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004202- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

4204 be updated back after the system call. Original patch by Brian Brazil.

4211
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004212- Issue #808164: Fixed socket.close to avoid references to globals, to

4216 can be set to False to turn off the previously undocumented 'popularity'
4217 heuristic. Patch by Terry Reedy and Eli Bendersky
4218

4220 falling into recursion.
4221
R. David Murray7c4bf552010-08-25 01:45:57 +00004222- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4223 character years even if the message contains RFC822 two character years.
4224
Daniel Stutzbach91287322010-08-24 21:09:30 +00004225- Issue #8750: Fixed MutableSet's methods to correctly handle

4237 module now correctly return a set. (Patch by Eli Bendersky.)
4238
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004239- Issue #9617: Signals received during a low-level write operation aren't
4240 ignored by the buffered IO layer anymore.
4241
Benjamin Peterson52c36052010-08-21 03:03:22 +00004242- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4243 are not held onto after they are deleted elsewhere.
4244
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004245- Issue #9626: the view methods for collections.OrderedDict() were returning

4251 without this marker will not be overwritten or removed.
4252
Antoine Pitroue1436d12010-08-12 15:25:51 +00004253- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4254 and a BadZipfile error is raised if it doesn't match (as used to be the
4255 case in Python 2.5 and earlier).
4256
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004257- Issue #9550: a BufferedReader could issue an additional read when the
4258 original read request had been satisfied, which could block indefinitely
4259 when the underlying raw IO channel was e.g. a socket. Report and original
4260 patch by Jason V. Miller.
4261
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004262- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00004280- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4281 This is how it is supposed to work, wget and curl do the same. Previous
4282 behavior was wrong.

4290 the option character for the added 'h/help' option if prefix_chars
4291 does not contain a '-', instead of raising an error.
4292

4652 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4653 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

4665 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

5033-----------------
5034
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005035- Issue #7301: Add environment variable $PYTHONWARNINGS.
5036
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005037- Issue #8329: Don't return the same lists from select.select when no fds are
5038 changed.
5039
Georg Brandlfee0f442010-05-22 21:26:21 +00005040- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005041 on 64-bit machines. The shift count for either left or right shift is
5042 permitted to be up to sys.maxsize.

5049
Georg Brandlfee0f442010-05-22 21:26:21 +00005050- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5051 with a non-empty format string. This is an effort to future-proof user
5052 code. If a derived class does not currently implement __format__ but later
5053 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005054 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005055 Python 3.3 and it will be an error in Python 3.4.

5087
Georg Brandlfee0f442010-05-22 21:26:21 +00005088- Issue #8257: The Decimal construct now accepts a float instance directly,
5089 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005090
5091 >>> Decimal(1.1)
5092 Decimal('1.100000000000000088817841970012523233890533447265625')
5093
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005094- collections.Counter() now supports a subtract() method.
5095
Georg Brandlfee0f442010-05-22 21:26:21 +00005096- The functools module now has a total_ordering() class decorator to simplify
5097 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00005099- The functools module also adds cmp_to_key() as a tool to transition old-style
5100 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005101
Georg Brandlfee0f442010-05-22 21:26:21 +00005102- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5103 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00005105- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5106 InvalidOperation instead of returning False. (Comparisons involving a quiet
5107 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5108 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005109
Georg Brandlfee0f442010-05-22 21:26:21 +00005110- Issue #2531: Comparison operations between floats and Decimal instances now
5111 return a result based on the numeric values of the operands; previously they
5112 returned an arbitrary result based on the relative ordering of id(float) and
5113 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005114
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005115- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005116 argument `-` which tells it to read files to compile from stdin. Each line is
5117 read on demand and the named file is compiled immediately. (Original patch by
5118 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00005123- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5124 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005125 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005126
Georg Brandlfee0f442010-05-22 21:26:21 +00005127- Comparisons using one of <, <=, >, >= between a complex instance and a
5128 Fractions instance now raise TypeError instead of returning True/False. This
5129 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5130 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005229- Issue #8300: When passing a non-integer argument to struct.pack with any
5230 integer format code, struct.pack first attempts to convert the non-integer
5231 using its __index__ method. If that method is non-existent or raises
5232 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00005234- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5235 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5236 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005237 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5238 inconsistent: __int__ was used for some integer codes but not for others, and
5239 the set of integer codes for which it was used differed between native packing
5240 and standard packing.)

5451
Georg Brandlba83f822010-03-14 09:50:54 +00005452- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
5453 now also used by regrtest to run all the tests in a temporary directory. The
5454 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
5455 Xicluna who helped with the patch.

5472 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005473 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00005492- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5493 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5494 returning NULL. The macro now returns a statically allocated empty string
5495 instead.

5505 strings,
5506 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5507 numeric strings corresponding to subnormal values,
5508 (3) a memory leak for some values large enough to cause overflow, and
5509 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005540- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005541 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005547- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005548 file position when calling `truncate()`. It would previously change the file
5549 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005550 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5551
Georg Brandlba83f822010-03-14 09:50:54 +00005552- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5553 class used to represent files stored inside an archive. The new
5554 implementation is significantly faster and can be wrapped in a
5555 ``io.BufferedReader`` object for more speedups. It also solves an issue
5556 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5557 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00005567- Issue #7748: Since unicode values are supported for some metadata options in
5568 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5569 encoded string for them. This ensures that the upload and register commands
5570 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005647- The ``__complex__()`` method is now looked up on the class of instances to
5648 make it consistent with other special methods.

5652
Mark Dickinson1b34d252010-01-01 17:27:30 +00005653- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005654 DeprecationWarning when passed a float argument where an integer was expected.
5655 These functions and methods now raise TypeError instead. The majority of the
5656 effects of this change are in the extension modules, but some core functions
5657 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5658 and many unicode/str methods.

5672 of integers: the result of a/b is now correctly rounded for ints a and b (at
5673 least on IEEE 754 platforms), and in particular does not depend on the
5674 internal representation of a long.

5682
Georg Brandlba83f822010-03-14 09:50:54 +00005683 These executables now work properly with the arch(1) command: ``arch -ppc
5684 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005840- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5841 decimal string that's guaranteed to round back to x under correct rounding
5842 (with round-half-to-even rounding mode). Previously it gave a string based on
5843 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5844 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5845 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005846
Georg Brandlba83f822010-03-14 09:50:54 +00005847- Issue #7117: On almost all platforms: float-to-string and string-to-float
5848 conversions within Python are now correctly rounded. Places these conversions
5849 occur include: str for floats and complex numbers; the float and complex
5850 constructors; old-style and new-style numeric formatting; serialization and
5851 deserialization of floats and complex numbers using marshal, pickle and json;
5852 parsing of float and imaginary literals in Python code; Decimal-to-float
5853 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005854
Georg Brandlba83f822010-03-14 09:50:54 +00005855 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5856 providing correctly-rounded strtod and dtoa C functions. This code is
5857 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5858 the C compiler. There may be a small number of platforms on which correct
5859 operation of this code cannot be guaranteed, so the code is not used: notably,
5860 this applies to platforms where the C double format is not IEEE 754 binary64,
5861 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5862 and Python's configure script is unable to determine how to change the FPU
5863 precision. On these platforms conversions use the platform strtod and dtoa,
5864 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005865
Georg Brandlba83f822010-03-14 09:50:54 +00005866- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5867 uses the correctly-rounded string <-> float conversions described above (when
5868 available), and so produces correctly rounded results that will display nicely
5869 under the float repr. There are two related small changes: (1) round now
5870 accepts any class with an ``__index__()`` method for its second argument (but
5871 no longer accepts floats for the second argument), and (2) an excessively
5872 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5873 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006020- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6021 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6022 but with at least one decimal point and with a default precision
6023 of 12. Previously, the behavior the same but with a default precision of 6.
6024 This more closely matches ``str()``, and reduces surprises when adding
6025 alignment flags to the empty presentation type. This also affects the new
6026 complex.__format__ in the same way.
6027

Georg Brandlba83f822010-03-14 09:50:54 +00006147- Issue #4935: The overflow checking code in the expandtabs() method common to
6148 str, bytes and bytearray could be optimized away by the compiler, letting the
6149 interpreter segfault instead of raising an error.

6159 collecting the oldest generation) so that allocating lots of objects without

6165
Georg Brandlba83f822010-03-14 09:50:54 +00006166- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6167 existing .py counterpart, override the co_filename attributes of all code
6168 objects if the original filename is obsolete (which can happen if the file has
6169 been renamed, moved, or if it is accessed through different paths). Patch by

6210 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6211 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006214- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6216 instead of throwing a MemoryError.
6217
Georg Brandlba83f822010-03-14 09:50:54 +00006218- Issue #3689: The list reversed iterator now supports __length_hint__ instead

6223
Georg Brandlba83f822010-03-14 09:50:54 +00006224- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6225 file objects with closefd=False. The file descriptor is still kept open but
6226 the file object behaves like a closed file. The ``FileIO`` object also got a
6227 new readonly attribute ``closefd``.

6246
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006247- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00006248 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00006250- On windows, ``os.chdir()`` given unicode was not working if
6251 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6252 this code path is really executed because I cannot move to such directory on
6253 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00006254
Georg Brandlba83f822010-03-14 09:50:54 +00006255- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6256 element is temporarily replaced with an equivalent frozenset. But the
6257 eventual KeyError would always report the empty ``frozenset()`` as the missing
6258 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006278- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6279 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6280 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6281 of using the replace error handler in PyUnicode_DecodeUTF8().
6282
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006283- Issue #3739: The unicode-internal encoder now reports the number of characters

6285
Georg Brandlba83f822010-03-14 09:50:54 +00006286- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6287 allocator will be automatically disabled when running under Valgrind. This
6288 gives improved memory leak detection when running under Valgrind, while taking
6289 advantage of pymalloc at other times.

7537 threads could return successfully while some Thread objects were still
7538 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00007555- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7556 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00007557 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7558 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00007563- Issue #5354: New test support function import_fresh_module() makes it easy to
7564 import both normal and optimised versions of modules. test_heapq and
7565 test_warnings have been adjusted to use it, tests for other modules with both
7566 C and Python implementations in the stdlib can be adjusted to use it over
7567 time.

Georg Brandlba83f822010-03-14 09:50:54 +00007575- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
7576 should cause a test to be skipped are now done using import_module from test
7577 support, which does the conversion.

7679
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007680- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7681 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7682 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7683 ``printf`` function, whereas PyString_FromFormat has an independent
7684 implementation and uses "%zd" on all platforms for size_t values.
7685 This makes a difference on win64, where ``printf`` needs "%Id" to display
7686 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007688- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7692 object; previously an int would be returned for small values. the __long__
7693 method is allowed to return either an int or a long, but the behaviour of
7694 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007703 was correctly parsed but parsing of subsequent arguments failed.
7704
Vinay Sajip35e3b032008-09-01 14:33:59 +00007705- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007706 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7707 mechanism. In the process, fix a bug where isinstance() and issubclass(),

7709 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7710 type object.

7807
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007808- Issue #2975: When compiling several extension modules with Visual Studio 2008
7809 from the same python interpreter, some environment variables would grow
7810 without limit.
7811
Benjamin Peterson37346b22008-08-23 20:27:43 +00007812- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7813 exploitation of poor argument checking.
7814
Gerhard Häringef2276b2008-09-12 13:54:06 +00007815- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

7828 wrapper for warnings.catch_warnings() that makes it easier to check
7829 that expected warning messages are being reported.
7830
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00007831- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007849What's New in Python 2.6 beta 3?
7850================================
7851
Barry Warsaw07a4a382008-08-21 01:15:08 +00007852*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007853
7854Core and Builtins
7855-----------------
7856
Guido van Rossumf8402962008-08-20 15:01:50 +00007857- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7858 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7859 extensions do not automatically benefit from the class attribute
7860 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7861 to their tp_flags field if they care. This is a backwards
7862 compatibility feature; in 3.0, all types will use the cache by
7863 default.
7864
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007865- Keyword arguments can now follow starred arguments. (``f(a, *args,
7866 keyword=23)`` is now valid syntax.)
7867
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007868- ctypes function pointers that are COM methods have a boolean True
7869 value again.
7870
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007871- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7872 by denying s# to parse objects that have a releasebuffer procedure,
7873 and introducing s*.
7874
Georg Brandl1e13ea92008-08-11 09:07:59 +00007875- Issue #3537: Fix an assertion failure when an empty but presized dict
7876 object was stored in the freelist.
7877
Mark Dickinsonb6467572008-08-04 21:30:09 +00007878- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7879 ValueError consistently across platforms.
7880
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007881- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7882 (64bit Unix, for example), unichr() would truncate its argument and return
7883 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7884
Neal Norwitze7d8be82008-07-31 17:17:14 +00007885- Apply security patches from Apple.
7886
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007887- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7888 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7889
Antoine Pitrou92f82162008-07-25 22:22:08 +00007890- Issue #1819: function calls with several named parameters are now on
7891 average 35% faster (as measured by pybench).
7892
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007893- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7894 the python debugger steps into a class statement: the free variables (local
7895 variables defined in an outer scope) would be deleted from the outer scope.
7896
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007897- Issue #2620: Overflow checking when allocating or reallocating memory
7898 was not always being done properly in some python types and extension
7899 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7900 all been updated to perform better checks and places in the code that
7901 would previously leak memory on the error path when such an allocation
7902 failed have been fixed.
7903
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007904Library
7905-------
7906
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007907- Issue #3612: Added some missing basic types in ctypes.wintypes.
7908
Benjamin Petersone977ad42008-08-20 01:42:01 +00007909- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7910 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7911
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007912- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7913 version reported by these tools does not necessarily follow the python
7914 version numbering scheme, so the module is less strict when parsing it.
7915
Nick Coghlanf70385a2008-08-18 12:42:46 +00007916- Issue #2235: Added Py3k warnings for types which will become unhashable
7917 under the stricter __hash__ inheritance rules in 3.0. Several types
7918 which did not meet the rules for hash invariants and were already
7919 unhashable in 3.0 have now been explicitly flagged as unhashable in
7920 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7921 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7922
Brett Cannon88f801d2008-08-18 00:46:22 +00007923- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7924 imported into the module but exposed as part of the module's API.
7925
Brett Cannon7b96f072008-08-18 00:41:11 +00007926- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7927
Brett Cannon46225e72008-08-18 00:36:52 +00007928- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7929
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007930- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7931
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007932- Issue #3575: Incremental decoder's decode function now takes bytearray
7933 by using 's*' instead of 't#'.
7934
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007935- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007936 fails unicode conversion on 2nd parameter. (windows only)
7937
Georg Brandl222e2082010-08-01 22:27:39 +00007938- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007939 in a redirect.
7940
Brett Cannonabe423e2008-08-16 21:47:07 +00007941- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007942 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007943
Facundo Batistaeb90b782008-08-16 14:44:07 +00007944- Issue #2776: fixed small issue when handling an URL with double slash
7945 after a 302 response in the case of not going through a proxy.
7946
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007947- Issue #2676: in the email package, content-type parsing was hanging on
7948 pathological input because of quadratic or exponential behaviour of a
7949 regular expression.
7950
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007951- Issue #3476: binary buffered reading through the new "io" library is now
7952 thread-safe.
7953
Brett Cannonbf3157b2008-08-14 05:00:03 +00007954- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7955 since mimetools itself is deprecated. Because modules are cached, all
7956 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7957
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007958- Issue #3134: shutil referenced undefined WindowsError symbol.
7959
Robert Schuppenies14646332008-08-10 11:01:53 +00007960- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7961 menu entries were not deleted.
7962
Brett Cannon83e81842008-08-09 23:30:55 +00007963- Copied the implementation of reduce() to _functools.reduce() to have a
7964 version that did not raise a DeprecationWarning under -3.
7965
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007966- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7967 a MemoryError rather than silently stop the iteration.
7968
Guido van Rossum59ce9012008-08-09 14:55:34 +00007969- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7970 to _sre.compile() will now be rejected. This should not affect anybody
7971 since the re.compile() function never generates invalid re-bytecode.
7972
Skip Montanaroa032bf42008-08-08 22:52:51 +00007973- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7974 upon first access it can be automatically initialized from the csv file if
7975 it wasn't initialized during instantiation.
7976
Brett Cannon3aa2a492008-08-06 22:28:09 +00007977- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7978 the reload() built-in has been removed.
7979
Brett Cannon7e30b672008-08-04 21:52:25 +00007980- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007981 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007982 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7983 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7984 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7985 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7986 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007987
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007988- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7989 raised an AttributeError.
7990
Benjamin Peterson01a24322008-07-28 23:35:27 +00007991- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007992 asking for a specific length. This problem only affected files opened
7993 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007994
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007995- Issue #3449: Update decimal module to use most recent specification
7996 (v. 1.68) and tests (v. 2.58) from IBM.
7997
Georg Brandl222e2082010-08-01 22:27:39 +00007998- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007999

8002
Georg Brandlf9efabb2008-07-23 15:16:45 +00008003- Deprecate the "ast" parser function aliases.
8004
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008005- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
8006
8007- Issue #3303: Fix a crash in locale.strcoll() when calling it with
8008 invalid arguments.
8009
8010- Issue #3302: Fix several crashes when calling locale's gettext functions
8011 with None arguments.
8012
8013- Issue #3389: Allow resolving dotted names for handlers in logging
8014 configuration files.
8015

8017
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008018- Issue #3394: zipfile.writestr sets external attributes when passed a
8019 file name rather than a ZipInfo instance, so files are extracted with
8020 mode 0600 rather than 000 under Unix.
8021
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008022- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8023 argument in python 2.5, this broke code that subclassed Popen to include its
8024 own poll method. Fixed my moving _deadstate to an _internal_poll method.

8032-------------
8033
Nick Coghlan6e8fef02008-08-18 13:14:22 +00008034- Issue #2235: the C API function PyObject_HashNotImplemented and its
8035 interaction with the tp_hash slot (added in 2.6b2) are now documented
8036
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008037- Issue #643841: The language reference now provides more detailed
8038 coverage of the lookup process for special methods. The disclaimers
8039 regarding lack of coverage of new-style classes have also been
8040 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008043What's New in Python 2.6 beta 2?
8044================================
8045
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008046*Release date: 17-Jul-2008*
8047
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008048Core and Builtins
8049-----------------
8050
Georg Brandl3e483f62008-07-16 22:57:41 +00008051- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8052 its methods now allow for items objects that can be converted to
8053 an integer using operator.index().
8054
Mark Dickinson64b7e502008-07-16 09:40:03 +00008055- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8056 produced a ValueError instead of giving the correct float.
8057
Eric Smitha5fa5a22008-07-16 00:11:49 +00008058- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8059 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8060
Mark Dickinson7103aa42008-07-15 19:08:33 +00008061- Issue #3008: the float type has a new instance method 'float.hex'
8062 and a new class method 'float.fromhex' to convert floating-point
8063 numbers to and from hexadecimal strings, respectively.
8064
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008065- Issue #2235: __hash__ is once again inherited by default. To allow
8066 collections.Hashable to remain meaningful in the presence of the
8067 default hash implementation (object.__hash__), it is now possible
8068 to explicit block inheritance of hash by setting __hash__=None at
8069 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8070 level.
8071
Nick Coghlanb028f502008-07-13 14:52:36 +00008072- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8073 the parent module cannot be found while performing an absolute import.
8074 This means that an incorrectly defined __package__ attribute will
8075 now only prevent relative imports in that module rather than causing
8076 all imports from that module to fail.
8077
Nick Coghlan14ff9942008-07-08 14:21:42 +00008078- Issue #2517: Allow unicode messages in Exceptions again by correctly
8079 bypassing the instance dictionary when looking up __unicode__ on
8080 new-style classes.
8081
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008082- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8083 set to a custom object whose write() method happens to install
8084 another file in sys.stdout.
8085
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008086- Issue #3088: Corrected a race condition in classes derived from
8087 threading.local: the first member set by a thread could be saved in
8088 another thread's dictionary.
8089
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008090- Issue #3004: Minor change to slice.indices(): the start and stop
8091 arguments are now treated identically, making the behaviour easier
8092 to describe and understand. For example, slice(None, -10,
8093 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8094 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00008547 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008548
8549 This is controlled by the configure argument ``--with-universal-archs``:
8550
8551 - ``--with-universal-archs=all``: install 4-way universal
8552
8553 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8554
8555 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8556

Georg Brandl3ee81df2008-05-17 18:14:43 +00008608- Issue #1631171: Re-implement the 'warnings' module in C (the
8609 original Python code has been kept as backup). This will allow for
8610 using the 'warning's machinery in such places as the parser where
8611 use of pure Python code is not possible. Both the ``showarning()``
8612 and ``formatwarning()`` gain an optional 'line' argument which is
8613 not called by default for backwards-compatibility reasons. Setting
8614 ``warnings.showwarning()`` to an implementation that lacks support
8615 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008678- Issue #2550: The approach used by client/server code for obtaining
8679 ports to listen on in network-oriented tests has been refined in an
8680 effort to facilitate running multiple instances of the entire
8681 regression test suite in parallel without issue.
8682 test_support.bind_port() has been fixed such that it will always
8683 return a unique port -- which wasn't always the case with the
8684 previous implementation, especially if socket options had been set
8685 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8686 new implementation of bind_port() will actually raise an exception
8687 if it is passed an AF_INET/SOCK_STREAM socket with either the
8688 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8689 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8690 the socket it's been passed. This currently only applies to
8691 Windows. This option prevents any other sockets from binding to the
8692 host/port we've bound to, thus removing the possibility of the
8693 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8694 when a second SOCK_STREAM socket binds and accepts to a host/port
8695 that's already been bound by another socket. The optional preferred
8696 port parameter to bind_port() has been removed. Under no
8697 circumstances should tests be hard coding ports!
8698
8699 test_support.find_unused_port() has also been introduced, which will
8700 pass a temporary socket object to bind_port() in order to obtain an
8701 unused port. The temporary socket object is then closed and
8702 deleted, and the port is returned. This method should only be used
8703 for obtaining an unused port in order to pass to an external program
8704 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8705 a parameter to a server-oriented class that doesn't give you direct
8706 access to the underlying socket used.
8707
8708 Finally, test_support.HOST has been introduced, which should be used
8709 for the host argument of any relevant socket calls (i.e. bind and
8710 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008711
8712 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008713 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008714 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8715 test_asynchat and test_socket_ssl.
8716
Georg Brandl3ee81df2008-05-17 18:14:43 +00008717 It is now possible for multiple instances of the regression test
8718 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008997- Added the future_builtins module, which contains hex() and oct().
8998 These are the PEP 3127 version of these functions, designed to be
8999 compatible with the hex() and oct() builtins from Python 3.0. They
9000 differ slightly in their output formats from the existing, unchanged
9001 Python 2.6 builtins. The expected usage of the future_builtins
9002 module is:
9003 from future_builtins import hex, oct
9004
Eric Smith7ef40bf2008-02-20 23:34:22 +00009005- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9006 exponents for exponents with absolute value < 100. Follows C99
9007 standard. This is a change on Windows, which would use 3 digits.
9008 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9009 so that any alterations it does to the resulting string will be
9010 available in stringlib/formatter.h (for float.__format__).
9011
Eric Smith5a3c1352008-02-19 13:21:56 +00009012- Implemented PEP 3101, Advanced String Formatting. This adds a new
9013 builtin format(); a format() method for str and unicode; a
9014 __format__() method to object, str, unicode, int, long, float, and
9015 datetime; the class string.Formatter; and the C API
9016 PyObject_Format().
9017
Georg Brandl3ee81df2008-05-17 18:14:43 +00009018- Fixed several potential crashes, all caused by specially crafted
9019 __del__ methods exploiting objects in temporarily inconsistent
9020 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009021
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009022- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009023 prevent a possible crash: an Abstract Base Class would try to access
9024 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009025

Georg Brandl3ee81df2008-05-17 18:14:43 +00009029- Clear all free lists during a gc.collect() of the highest generation
9030 in order to allow pymalloc to free more arenas. Python may give back
9031 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009032
Georg Brandl3ee81df2008-05-17 18:14:43 +00009033- Issue #2045: Fix an infinite recursion triggered when printing a
9034 subclass of collections.defaultdict, if its default_factory is set
9035 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009036
Christian Heimesf75dbef2008-02-08 00:11:31 +00009037- Fixed a minor memory leak in dictobject.c. The content of the free
9038 list was not freed on interpreter shutdown.
9039
Georg Brandl21e99f42010-03-07 15:23:59 +00009040- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009041 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009042
Georg Brandl3ee81df2008-05-17 18:14:43 +00009043- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9044 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009045 to compact the internal free lists of pre-allocted ints and floats.
9046
Georg Brandl3ee81df2008-05-17 18:14:43 +00009047- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9048 calls. Python expected the return type int but the fork familie
9049 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009050
Georg Brandl3ee81df2008-05-17 18:14:43 +00009051- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00009063- Patch #1473257: generator objects gain a gi_code attribute. This is
9064 the same object as the func_code attribute of the function that
9065 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009066
Georg Brandl3ee81df2008-05-17 18:14:43 +00009067- Issue #1920: "while 0" statements were completely removed by the
9068 compiler, even in the presence of an "else" clause, which is
9069 supposed to be run when the condition is false. Now the compiler
9070 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009071
Guido van Rossumeead05f2008-01-24 18:21:02 +00009072- A few crashers fixed: weakref_in_del.py (issue #1377858);
9073 loosing_dict_ref.py (issue #1303614, test67.py);
9074 borrowed_ref_[34].py (not in tracker).
9075
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009076- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009077 suppressed while an extension is loaded by calling SetErrorMode in
9078 dynload_win.c. The error is still reported properly.
9079
Georg Brandl3ee81df2008-05-17 18:14:43 +00009080- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009081 several extension methods and modules do not work without unicode
9082 support.
9083
Georg Brandl26543b12008-01-21 18:36:51 +00009084- Issue #1882: when compiling code from a string, encoding cookies in the
9085 second line of code were not always recognized correctly.
9086
Georg Brandl14404b62008-01-19 19:27:05 +00009087- Issue #1679: "0x" was taken as a valid integer literal.
9088
Georg Brandl6caad7d2008-01-26 14:19:22 +00009089- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009090 added.
9091
Christian Heimesc94e2b52008-01-14 04:13:37 +00009092- sys.float_info / PyFloat_GetInfo: The floating point information
9093 object was converted from a dict to a specialized structseq object.
9094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Patch #1816: Added sys.flags structseq. It exposes the status of
9096 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009159- Patch #1739468: Directories and zipfiles containing a __main__.py
9160 file can now be directly executed by passing their name to the
9161 interpreter. The directory/zipfile is automatically inserted as the
9162 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009164- Issue #1265: Fix a problem with sys.settrace, if the tracing
9165 function uses a generator expression when at the same time the
9166 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009167
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009168- sets and frozensets now have an isdisjoint() method.

9173
Georg Brandl21e99f42010-03-07 15:23:59 +00009174- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9176 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009177
Georg Brandl3ee81df2008-05-17 18:14:43 +00009178- Issue #1686386: Tuple's tp_repr did not take into account the
9179 possibility of having a self-referential tuple, which is possible
9180 from C code. Nor did object's tp_str consider that a type's tp_str
9181 could do something that could lead to an inifinite recursion.
9182 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9183 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009184
Georg Brandl3ee81df2008-05-17 18:14:43 +00009185- Issue #1164: It was possible to trigger deadlock when using the
9186 'print' statement to write to a file since the GIL was not released
9187 as needed. Now PyObject_Print() does the right thing along with
9188 various tp_print implementations of the built-in types and those in
9189 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009190
Georg Brandl3ee81df2008-05-17 18:14:43 +00009191- Issue #1147: Exceptions were directly allowing string exceptions in
9192 their throw() method even though string exceptions no longer
9193 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00009197
Brett Cannon1e534b52007-09-07 04:18:30 +00009198- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009199 PyObject_Call() never calling back out to Python code to trigger
9200 recursion depth updates/checks. Required the creation of a static
9201 RuntimeError instance in case normalizing an exception put the
9202 recursion check value past its limit. Fixes crashers
9203 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009204

Neal Norwitz0ac60192007-05-27 04:08:54 +00009218- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009219 __*__ attributes. (Some already existed, e.g., __doc__ and
9220 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009221
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009222- Add -3 option to the interpreter to warn about features that are
9223 deprecated and will be changed/removed in Python 3.0.
9224
Georg Brandl2134e752007-05-21 20:34:16 +00009225- Patch #1686487: you can now pass any mapping after '**' in function
9226 calls.
9227
Collin Winter62903052007-05-18 23:11:24 +00009228- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009229 "except E as target:". This is to provide forwards compatibility
9230 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009231
Brett Cannon229cee22007-05-05 01:34:02 +00009232- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009237- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009238 setting a plain string, ie don't expand to single letter identifiers.
9239
Raymond Hettinger13936692007-04-11 18:40:58 +00009240- Request #1191699: Slices can now be pickled.
9241
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009242- Request #1193128: str.translate() now allows a None argument for
9243 translations that only remove characters without re-mapping the
9244 remaining characters.
9245
Georg Brandl5cb76c12007-03-21 09:00:39 +00009246- Patch #1682205: a TypeError while unpacking an iterable is no longer

9250
Guido van Rossum143b5642007-03-23 04:58:42 +00009251- Bug #1683368: The object.__init__() and object.__new__() methods are
9252 now stricter in rejecting excess arguments. The only time when
9253 either allows excess arguments is when it is not overridden and the
9254 other one is. For backwards compatibility, when both are
9255 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009256 warning later). Also, type.__init__() insists on the same signature
9257 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009258
Georg Brandl3ee81df2008-05-17 18:14:43 +00009259- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9260 object to complex using its __complex__() method before falling back
9261 to the __float__() method. Therefore, the functions in the cmath
9262 module now can operate on objects that define a __complex__()
9263 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009264
Georg Brandl3ee81df2008-05-17 18:14:43 +00009265- Patch #1623563: allow __class__ assignment for classes with
9266 __slots__. The old and the new class are still required to have the
9267 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009268

9273 ``object.__reduce_ex__()`` is called with an object that is faking
9274 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009275
Georg Brandl3ee81df2008-05-17 18:14:43 +00009276- Patch #1680015: Don't modify __slots__ tuple if it contains an

9280
Georg Brandl7b9c5552007-03-12 14:30:05 +00009281- Bug #1678647: write a newline after printing an exception in any
9282 case, even when converting the value to a string failed.
9283
Georg Brandl871f1bc2007-03-12 13:17:36 +00009284- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285 its argument, if it exists. If not, it will work like before. This
9286 allows customizing the output of dir() in the presence of a
9287 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009295- Patch #1491866: change the complex() constructor to allow
9296 parthensized forms. This means complex(repr(x)) now works instead of
9297 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009298
Georg Brandlaa2321b2007-03-07 00:40:28 +00009299- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009300 makes the filenames the warning module prints much more sensible
9301 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009314- Patch #1674228: when assigning a slice (old-style), check for the
9315 sq_ass_slice instead of the sq_slice slot.
9316
Georg Brandl3ee81df2008-05-17 18:14:43 +00009317- When printing an unraisable error, don't print exceptions. before
9318 the name. This duplicates the behavior whening normally printing
9319 exceptions.

9884
Georg Brandl92a6bae2007-03-13 17:43:32 +00009885- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

9943 TestCase and TestSuite subclasses (not instances) are no longer
9944 accepted in TestSuite.addTest(). This should cause no
9945 incompatibility since it never made sense with ordinary subclasses
9946 -- the failure just occurred later, with a more cumbersome
9947 exception.

10216 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010217
Georg Brandl3ee81df2008-05-17 18:14:43 +000010218- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010227- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010228 that the SMTP.starttls() caller no longer needs to call ehlo()
10229 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010230 does not claim to support starttls. Adds the
10231 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010274- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010275 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +000010283- itertools.starmap() now accepts any iterable input. Previously, it

10312 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10313 silently miscode subclasses of those types. Now, it raises a
10314 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010315

Georg Brandl3ee81df2008-05-17 18:14:43 +000010330 time so that opening a database previously created with the DB_DUP
10331 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10332 opens. Specifically: dictionary assignment to a DB object will
10333 replace all values for a given key when the database allows
10334 duplicate values. DB users should use DB.put(k, v) when they want
10335 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010336
Gregory P. Smithac11e022007-11-05 02:56:31 +000010337- Add the bsddb.db.DBEnv.lock_id_free method.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010341- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10342 characters with ASCII value less than 32. Also, it correctly quotes
10343 dots only if they occur on a single line, as opposed to the previous
10344 behavior of quoting dots if they are the second character of any
10345 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010346
Georg Brandla47337f2007-03-13 12:34:25 +000010347- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010620- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +000010621 periodic threadstate and signal checking in tight loops. By
10622 default, this option is turned-off. It should only be enabled in
10623 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010624

10674
Georg Brandl3ee81df2008-05-17 18:14:43 +000010675- Unified naming convention for free lists and their limits. All free
10676 lists in Object/ are named ``free_list``, the counter ``numfree``
10677 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10678 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010679
Georg Brandl3ee81df2008-05-17 18:14:43 +000010680- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10681 to ``PyTuple_SetItem``, it can be used to populate a brand new
10682 frozenset; but it does not steal a reference to the added item.

10691
10692- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10693 ``PyFloat_GetInfo()`` to the float API.
10694
Georg Brandl3ee81df2008-05-17 18:14:43 +000010695- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10696 of w# format code incorrectly truncated the length to an int, even
10697 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10698 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010699
Georg Brandl3ee81df2008-05-17 18:14:43 +000010700- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10704 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10705 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010706
Georg Brandl3ee81df2008-05-17 18:14:43 +000010707- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10708 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010709
10710- Patch #1733960: Allow T_LONGLONG to accept ints.

10717
10718- Fix some leftovers from the conversion from int to Py_ssize_t
10719 (relevant to strings and sequences of more than 2**31 items).
10720
10721- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10722 outside of pystate.c and should not be necessary.
10723
Georg Brandl3ee81df2008-05-17 18:14:43 +000010724- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10725 absolute imports. In earlier versions they might have used relative
10726 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010727
Georg Brandl3ee81df2008-05-17 18:14:43 +000010728- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10729 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010730
Georg Brandl3ee81df2008-05-17 18:14:43 +000010731- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010737- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10738 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10739 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10740 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010741

Georg Brandl3ee81df2008-05-17 18:14:43 +000010754- Removed the macfs module. It had been deprecated since Python 2.5.
10755 This lead to the deprecation of macostools.touched() as it relied
10756 solely on macfs and was a no-op under OS X.
