972 the newer 10.5+ 32-bit-only format;
973 and the unchanged 10.6+ 64-/32-bit format.
974 Although binary installers will no longer be available from
975 python.org as of 2.7.8, it will still be possible to build from
976 source on 10.3.9 and 10.4 systems if necessary.
977 See Mac/BuildScript/README.txt for more information.

2100 especially problematic for the FileType type, as a default file would always
2101 be opened, even if a file argument was specified on the command line.

2359 32-bit-only installer Pythons on systems with Xcode 4 (currently
2360 OS X 10.8, 10.7, and optionally 10.6).
2361 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2362 * Since Xcode 4 removes ppc support, extension module builds now
2363 check for ppc compiler support and by default remove ppc and
2364 ppc64 archs when they are not available.
2365 * Extension module builds now revert to using system installed
2366 headers and libs (/usr and /System/Library) if the SDK used
2367 to build the interpreter is not installed or has moved.
2368 * Try to avoid building extension modules with deprecated
2369 and problematic Apple llvm-gcc compiler. If original compiler
2370 is not available, use clang instead by default.

2733
Mark Dickinsondbbed042011-09-19 16:38:08 +01002734- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2735 int.__pow__. These overflow checks were causing int.__pow__ to produce
2736 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002737 compiler optimizing the check away. Also fix similar overflow checks
2738 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2739 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02002750- Issue #12149: Update the method cache after a type's dictionnary gets
2751 cleared by the garbage collector. This fixes a segfault when an instance
2752 and its type get caught in a reference cycle, and the instance's
2753 deallocator calls one of the methods on the type (e.g. when subclassing
2754 IOBase). Diagnosis and patch by Davide Rizzo.
2755
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002756- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002763 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2764 raw_input() interrupted by CTRL+c.
2765
Łukasz Langa7a153902011-10-18 17:16:00 +02002766- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01002807- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002808 has left two versions of customize_compiler, the original in
2809 distutils.sysconfig and another copy in distutils.ccompiler, with some
2810 parts of distutils calling one and others using the other.
2811 Complete the revert back to only having one in distutils.sysconfig as
2812 is the case in 3.x.
2813
Ned Deily0d0ea482012-02-10 12:59:06 +01002814- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2815 Distutils-based packages with C extension modules may fail because
2816 Apple has removed gcc-4.2, the version used to build python.org
2817 64-bit/32-bit Pythons. If the user does not explicitly override
2818 the default C compiler by setting the CC environment variable,
2819 Distutils will now attempt to compile extension modules with clang
2820 if gcc-4.2 is required but not found. Also as a convenience, if
2821 the user does explicitly set CC, substitute its value as the default
2822 compiler in the Distutils LDSHARED configuration variable for OS X.
2823 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2824 SDK, neither of which are available in Xcode 4. This change does not
2825 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003075- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3076 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3077 interpreter process. This could cause failures in non-Distutils subprocesses
3078 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003079 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003080 deployment target only in the environment of each build subprocess. It is
3081 still possible to globally override the default by setting
3082 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3083 greater or equal to the default value, the value with which the interpreter
3084 was built.

3113 updating the check interval, so if the user decreases the check interval,
3114 the ticker doesn't have to wind down to zero from the old starting point
3115 before the new interval takes effect. And if the user increases the
3116 interval, it makes sure the new limit takes effect right away rather have an
3117 early task switch before recognizing the new interval.

4115 This prevents user-created self-referencing ordered dictionaries from
4116 becoming permanently uncollectable GC garbage. The downside is that

4118 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004577- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4578 start byte and the continuation byte(s) are now considered invalid, instead
4579 of the number of bytes specified by the start byte.
4580 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4581 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4582 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4583 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004591- Issue #8748: Fix two issues with comparisons between complex and integer
4592 objects. (1) The comparison could incorrectly return True in some cases
4593 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4594 (2) The comparison raised an OverflowError for large integers, leading
4595 to unpredictable exceptions when combining integers and complex objects
4596 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004598- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004735- Issue #1533: Fix inconsistency in range function argument processing: any
4736 non-float non-integer argument is now converted to an integer (if possible)
4737 using its __int__ method. Previously, only small arguments were treated this
4738 way; larger arguments (those whose __int__ was outside the range of a C long)
4739 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004747 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004748 benefit compared to the dynamic memory allocation fallback. Patch by

4775 inheritance with the underlying socket object. The cheap inheritance has been
4776 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00004789- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4790 operation raises multiple signals and more than one of those signals is
4791 trapped, the specification determines the order in which the signals should be
4792 handled. In many cases this order wasn't being followed, leading to the wrong
4793 Python exception being raised.

4960Core and Builtins
4961-----------------
4962
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004963- Issue #7301: Add environment variable $PYTHONWARNINGS.
4964
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004965- Issue #8329: Don't return the same lists from select.select when no fds are
4966 changed.
4967
Georg Brandlfee0f442010-05-22 21:26:21 +00004968- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004969 on 64-bit machines. The shift count for either left or right shift is
4970 permitted to be up to sys.maxsize.
4971
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004972- Ensure that tokenization of identifiers is not affected by locale.
4973
Georg Brandlfee0f442010-05-22 21:26:21 +00004974- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004975
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004976- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4977
Georg Brandlfee0f442010-05-22 21:26:21 +00004978- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4979 with a non-empty format string. This is an effort to future-proof user
4980 code. If a derived class does not currently implement __format__ but later
4981 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004982 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004983 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004984
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004985- Issue #8268: Old-style classes (not just instances) now support weak
4986 references.
4987
Georg Brandlfee0f442010-05-22 21:26:21 +00004988- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4989 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004990
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004991- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00004993- Issue #6474: Make error message from passing an inadequate number of keyword
4994 arguments to a function correct.
4995
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004996- Issue #8164: Don't allow lambda functions to have a docstring.
4997
Victor Stinner66644262010-03-10 22:30:19 +00004998- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004999 (SIGINT). If an error occurs while importing the site module, the error is
5000 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005001 module.
5002
Collin Winter001a3952010-03-18 21:54:01 +00005003- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00005008- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
5009
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005010- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00005011 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
5012 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005013
Benjamin Peterson76a23c12010-04-04 23:23:22 +00005014- Issue #8310: Allow dis to examine new style classes.
5015
Georg Brandlfee0f442010-05-22 21:26:21 +00005016- Issue #8257: The Decimal construct now accepts a float instance directly,
5017 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005018
5019 >>> Decimal(1.1)
5020 Decimal('1.100000000000000088817841970012523233890533447265625')
5021
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005022- collections.Counter() now supports a subtract() method.
5023
Georg Brandlfee0f442010-05-22 21:26:21 +00005024- The functools module now has a total_ordering() class decorator to simplify
5025 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005026
Georg Brandlfee0f442010-05-22 21:26:21 +00005027- The functools module also adds cmp_to_key() as a tool to transition old-style
5028 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005029
Georg Brandlfee0f442010-05-22 21:26:21 +00005030- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5031 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005032
Georg Brandlfee0f442010-05-22 21:26:21 +00005033- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5034 InvalidOperation instead of returning False. (Comparisons involving a quiet
5035 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5036 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005037
Georg Brandlfee0f442010-05-22 21:26:21 +00005038- Issue #2531: Comparison operations between floats and Decimal instances now
5039 return a result based on the numeric values of the operands; previously they
5040 returned an arbitrary result based on the relative ordering of id(float) and
5041 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005042
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005043- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005044 argument `-` which tells it to read files to compile from stdin. Each line is
5045 read on demand and the named file is compiled immediately. (Original patch by
5046 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005047
Georg Brandlfee0f442010-05-22 21:26:21 +00005048- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
5049 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00005051- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5052 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005053 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005054
Georg Brandlfee0f442010-05-22 21:26:21 +00005055- Comparisons using one of <, <=, >, >= between a complex instance and a
5056 Fractions instance now raise TypeError instead of returning True/False. This
5057 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5058 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005059
Michael Foorde6410c52010-03-29 20:04:23 +00005060- Addition of ``WeakSet`` to the ``weakref`` module.

5068
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005069- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005070 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5071 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005072
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005073- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5074 deprecated.
5075
Georg Brandlfee0f442010-05-22 21:26:21 +00005076- Issue #7860: platform.uname now reports the correct 'machine' type when Python
5077 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00005078

5083 existing at the same time, causing a Unicode error when configuration code
5084 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00005085
Georg Brandlfee0f442010-05-22 21:26:21 +00005086- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
5087 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00005088
Antoine Pitroueee91cd2010-03-26 19:27:16 +00005089- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
5090 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
5091 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00005092
Florent Xiclunacf82fa62010-03-21 12:27:20 +00005093- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00005113- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00005114 for ``TimedRotatingFileHandler`` by using the modification time of an existing
5115 log file to compute the next rollover time. If the log file does not exist,
5116 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00005117
Georg Brandlba83f822010-03-14 09:50:54 +00005118- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

5125
Georg Brandlba83f822010-03-14 09:50:54 +00005126- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
5127 a base64 transfer-encoded payload *after* decoding it; it no longer does.
5128 This is a behavior change, so email's minor version number is now bumped, to
5129 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005157- Issue #8300: When passing a non-integer argument to struct.pack with any
5158 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00005162- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5163 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5164 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005165 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5166 inconsistent: __int__ was used for some integer codes but not for others, and
5167 the set of integer codes for which it was used differed between native packing
5168 and standard packing.)

5573-----------------
5574
Georg Brandlba83f822010-03-14 09:50:54 +00005575- The ``__complex__()`` method is now looked up on the class of instances to
5576 make it consistent with other special methods.

5580
Mark Dickinson1b34d252010-01-01 17:27:30 +00005581- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005582 DeprecationWarning when passed a float argument where an integer was expected.
5583 These functions and methods now raise TypeError instead. The majority of the
5584 effects of this change are in the extension modules, but some core functions
5585 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5586 and many unicode/str methods.

5600 of integers: the result of a/b is now correctly rounded for ints a and b (at
5601 least on IEEE 754 platforms), and in particular does not depend on the
5602 internal representation of a long.

5610
Georg Brandlba83f822010-03-14 09:50:54 +00005611 These executables now work properly with the arch(1) command: ``arch -ppc
5612 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005768- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5769 decimal string that's guaranteed to round back to x under correct rounding
5770 (with round-half-to-even rounding mode). Previously it gave a string based on
5771 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5772 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5773 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005774
Georg Brandlba83f822010-03-14 09:50:54 +00005775- Issue #7117: On almost all platforms: float-to-string and string-to-float
5776 conversions within Python are now correctly rounded. Places these conversions
5777 occur include: str for floats and complex numbers; the float and complex
5778 constructors; old-style and new-style numeric formatting; serialization and
5779 deserialization of floats and complex numbers using marshal, pickle and json;
5780 parsing of float and imaginary literals in Python code; Decimal-to-float
5781 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005782
Georg Brandlba83f822010-03-14 09:50:54 +00005783 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5784 providing correctly-rounded strtod and dtoa C functions. This code is
5785 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5786 the C compiler. There may be a small number of platforms on which correct
5787 operation of this code cannot be guaranteed, so the code is not used: notably,
5788 this applies to platforms where the C double format is not IEEE 754 binary64,
5789 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5790 and Python's configure script is unable to determine how to change the FPU
5791 precision. On these platforms conversions use the platform strtod and dtoa,
5792 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005794- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5795 uses the correctly-rounded string <-> float conversions described above (when
5796 available), and so produces correctly rounded results that will display nicely
5797 under the float repr. There are two related small changes: (1) round now
5798 accepts any class with an ``__index__()`` method for its second argument (but
5799 no longer accepts floats for the second argument), and (2) an excessively
5800 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5801 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005943
Georg Brandlba83f822010-03-14 09:50:54 +00005944 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5945 (2) parsing of strings representing infinities and nans was locale aware; and
5946 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005948- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5949 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5950 but with at least one decimal point and with a default precision
5951 of 12. Previously, the behavior the same but with a default precision of 6.
5952 This more closely matches ``str()``, and reduces surprises when adding
5953 alignment flags to the empty presentation type. This also affects the new
5954 complex.__format__ in the same way.
5955
5956- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

6151
Georg Brandlba83f822010-03-14 09:50:54 +00006152- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6153 file objects with closefd=False. The file descriptor is still kept open but
6154 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00006178- On windows, ``os.chdir()`` given unicode was not working if

6180 this code path is really executed because I cannot move to such directory on
6181 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006183- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6184 element is temporarily replaced with an equivalent frozenset. But the
6185 eventual KeyError would always report the empty ``frozenset()`` as the missing
6186 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006206- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6207 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6208 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6209 of using the replace error handler in PyUnicode_DecodeUTF8().
6210
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006211- Issue #3739: The unicode-internal encoder now reports the number of characters

6213
Georg Brandlba83f822010-03-14 09:50:54 +00006214- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6216 gives improved memory leak detection when running under Valgrind, while taking
6217 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00007491- Issue #5354: New test support function import_fresh_module() makes it easy to
7492 import both normal and optimised versions of modules. test_heapq and
7493 test_warnings have been adjusted to use it, tests for other modules with both
7494 C and Python implementations in the stdlib can be adjusted to use it over
7495 time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007608- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7609 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7610 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7611 ``printf`` function, whereas PyString_FromFormat has an independent
7612 implementation and uses "%zd" on all platforms for size_t values.
7613 This makes a difference on win64, where ``printf`` needs "%Id" to display
7614 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007634 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

7638 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00007785- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7786 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7787 extensions do not automatically benefit from the class attribute
7788 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7789 to their tp_flags field if they care. This is a backwards
7790 compatibility feature; in 3.0, all types will use the cache by
7791 default.
7792
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007793- Keyword arguments can now follow starred arguments. (``f(a, *args,
7794 keyword=23)`` is now valid syntax.)
7795
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007796- ctypes function pointers that are COM methods have a boolean True
7797 value again.
7798
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007799- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7800 by denying s# to parse objects that have a releasebuffer procedure,
7801 and introducing s*.
7802
Georg Brandl1e13ea92008-08-11 09:07:59 +00007803- Issue #3537: Fix an assertion failure when an empty but presized dict
7804 object was stored in the freelist.
7805
Mark Dickinsonb6467572008-08-04 21:30:09 +00007806- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7807 ValueError consistently across platforms.
7808
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007809- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7810 (64bit Unix, for example), unichr() would truncate its argument and return
7811 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7812
Neal Norwitze7d8be82008-07-31 17:17:14 +00007813- Apply security patches from Apple.
7814
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007815- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7816 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7817
Antoine Pitrou92f82162008-07-25 22:22:08 +00007818- Issue #1819: function calls with several named parameters are now on
7819 average 35% faster (as measured by pybench).
7820
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007821- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7822 the python debugger steps into a class statement: the free variables (local
7823 variables defined in an outer scope) would be deleted from the outer scope.
7824
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007825- Issue #2620: Overflow checking when allocating or reallocating memory
7826 was not always being done properly in some python types and extension
7827 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7828 all been updated to perform better checks and places in the code that
7829 would previously leak memory on the error path when such an allocation
7830 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007835- Issue #3612: Added some missing basic types in ctypes.wintypes.
7836
Benjamin Petersone977ad42008-08-20 01:42:01 +00007837- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7838 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7839
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007840- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7841 version reported by these tools does not necessarily follow the python
7842 version numbering scheme, so the module is less strict when parsing it.
7843
Nick Coghlanf70385a2008-08-18 12:42:46 +00007844- Issue #2235: Added Py3k warnings for types which will become unhashable
7845 under the stricter __hash__ inheritance rules in 3.0. Several types
7846 which did not meet the rules for hash invariants and were already
7847 unhashable in 3.0 have now been explicitly flagged as unhashable in
7848 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7849 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7850
Brett Cannon88f801d2008-08-18 00:46:22 +00007851- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7852 imported into the module but exposed as part of the module's API.
7853
Brett Cannon7b96f072008-08-18 00:41:11 +00007854- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7855
Brett Cannon46225e72008-08-18 00:36:52 +00007856- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7857
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007858- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7859
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007860- Issue #3575: Incremental decoder's decode function now takes bytearray
7861 by using 's*' instead of 't#'.
7862
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007863- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007864 fails unicode conversion on 2nd parameter. (windows only)
7865
Georg Brandl222e2082010-08-01 22:27:39 +00007866- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007867 in a redirect.
7868
Brett Cannonabe423e2008-08-16 21:47:07 +00007869- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007870 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007871
Facundo Batistaeb90b782008-08-16 14:44:07 +00007872- Issue #2776: fixed small issue when handling an URL with double slash
7873 after a 302 response in the case of not going through a proxy.
7874
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007875- Issue #2676: in the email package, content-type parsing was hanging on
7876 pathological input because of quadratic or exponential behaviour of a
7877 regular expression.
7878
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007879- Issue #3476: binary buffered reading through the new "io" library is now
7880 thread-safe.
7881
Brett Cannonbf3157b2008-08-14 05:00:03 +00007882- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7883 since mimetools itself is deprecated. Because modules are cached, all
7884 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7885
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007886- Issue #3134: shutil referenced undefined WindowsError symbol.
7887
Robert Schuppenies14646332008-08-10 11:01:53 +00007888- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7889 menu entries were not deleted.
7890
Brett Cannon83e81842008-08-09 23:30:55 +00007891- Copied the implementation of reduce() to _functools.reduce() to have a
7892 version that did not raise a DeprecationWarning under -3.
7893
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007894- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7895 a MemoryError rather than silently stop the iteration.
7896
Guido van Rossum59ce9012008-08-09 14:55:34 +00007897- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7898 to _sre.compile() will now be rejected. This should not affect anybody
7899 since the re.compile() function never generates invalid re-bytecode.
7900
Skip Montanaroa032bf42008-08-08 22:52:51 +00007901- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7902 upon first access it can be automatically initialized from the csv file if
7903 it wasn't initialized during instantiation.
7904
Brett Cannon3aa2a492008-08-06 22:28:09 +00007905- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7906 the reload() built-in has been removed.
7907
Brett Cannon7e30b672008-08-04 21:52:25 +00007908- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007909 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7917 raised an AttributeError.
7918
Benjamin Peterson01a24322008-07-28 23:35:27 +00007919- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007920 asking for a specific length. This problem only affected files opened
7921 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007922
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007923- Issue #3449: Update decimal module to use most recent specification
7924 (v. 1.68) and tests (v. 2.58) from IBM.
7925
Georg Brandl222e2082010-08-01 22:27:39 +00007926- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007927
Georg Brandl222e2082010-08-01 22:27:39 +00007928- Issue #1592: Improve error reporting when operations are attempted

7934
7935- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7936 invalid arguments.
7937
7938- Issue #3302: Fix several crashes when calling locale's gettext functions
7939 with None arguments.
7940
7941- Issue #3389: Allow resolving dotted names for handlers in logging
7942 configuration files.
7943
7944- Deprecate the sunaudio module for removal in Python 3.0.
7945
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007946- Issue #3394: zipfile.writestr sets external attributes when passed a
7947 file name rather than a ZipInfo instance, so files are extracted with
7948 mode 0600 rather than 000 under Unix.
7949
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007950- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7951 argument in python 2.5, this broke code that subclassed Popen to include its
7952 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007962- Issue #2235: the C API function PyObject_HashNotImplemented and its
7963 interaction with the tp_hash slot (added in 2.6b2) are now documented
7964
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007965- Issue #643841: The language reference now provides more detailed
7966 coverage of the lookup process for special methods. The disclaimers
7967 regarding lack of coverage of new-style classes have also been
7968 removed, since the coverage is now fairly reasonable.

7972================================
7973
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007974*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007976Core and Builtins
7977-----------------
7978
Georg Brandl3e483f62008-07-16 22:57:41 +00007979- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7980 its methods now allow for items objects that can be converted to
7981 an integer using operator.index().
7982
Mark Dickinson64b7e502008-07-16 09:40:03 +00007983- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7984 produced a ValueError instead of giving the correct float.
7985
Eric Smitha5fa5a22008-07-16 00:11:49 +00007986- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7987 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7988
Mark Dickinson7103aa42008-07-15 19:08:33 +00007989- Issue #3008: the float type has a new instance method 'float.hex'
7990 and a new class method 'float.fromhex' to convert floating-point
7991 numbers to and from hexadecimal strings, respectively.
7992
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007993- Issue #2235: __hash__ is once again inherited by default. To allow
7994 collections.Hashable to remain meaningful in the presence of the
7995 default hash implementation (object.__hash__), it is now possible
7996 to explicit block inheritance of hash by setting __hash__=None at
7997 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7998 level.
7999
Nick Coghlanb028f502008-07-13 14:52:36 +00008000- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8001 the parent module cannot be found while performing an absolute import.
8002 This means that an incorrectly defined __package__ attribute will
8003 now only prevent relative imports in that module rather than causing
8004 all imports from that module to fail.
8005
Nick Coghlan14ff9942008-07-08 14:21:42 +00008006- Issue #2517: Allow unicode messages in Exceptions again by correctly
8007 bypassing the instance dictionary when looking up __unicode__ on
8008 new-style classes.
8009
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008010- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8011 set to a custom object whose write() method happens to install
8012 another file in sys.stdout.
8013
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008014- Issue #3088: Corrected a race condition in classes derived from
8015 threading.local: the first member set by a thread could be saved in
8016 another thread's dictionary.
8017
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008018- Issue #3004: Minor change to slice.indices(): the start and stop
8019 arguments are now treated identically, making the behaviour easier
8020 to describe and understand. For example, slice(None, -10,
8021 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8022 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8023 10, -1).
8024
Georg Brandl278fc502008-07-19 12:46:12 +00008025- Issue #3219: Calling a function with repeated keyword arguments,
8026 f(a=2, a=23), would not cause a syntax error. This was a regression
8027 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008028
Georg Brandl278fc502008-07-19 12:46:12 +00008029- Issue #2862: Make int and float freelist management consistent with
8030 other freelists. Changes their CompactFreeList apis into
8031 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008032

8034-------
8035
Thomas Heller57adf222008-08-14 19:10:48 +00008036- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8037 api functions without holding the GIL, which could lead to a fatal
8038 error when they failed.
8039
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008040- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00008048- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8049 ForkingPickler.register() to resolve conflict with ctypes.
8050
Vinay Sajip51e65192008-07-18 09:01:10 +00008051- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008052
Thomas Heller880f5292008-07-15 19:39:38 +00008053- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8054 a valid dlerror() message.
8055
Thomas Heller2bad6572008-07-15 17:19:50 +00008056- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8057 incomplete structure was created.
8058
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008059- Issue #3339: dummy_thread.acquire() should not return None.
8060
Raymond Hettingerb01713e2008-07-10 14:34:57 +00008061- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
8062
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008063- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008064
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008065- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8066 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008067 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008068 content-length. The problem had been corrected in the 2.4 branch, but never
8069 merged into trunk.

8472
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008473- On MacOS X it is now possible to install the framework in 64-bit
8474 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008475 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008476
8477 This is controlled by the configure argument ``--with-universal-archs``:
8478
8479 - ``--with-universal-archs=all``: install 4-way universal
8480
8481 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8482
8483 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8484
8485 This option should be used in combination with ``--enable-universalsdk=``.
8486
8487 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008536- Issue #1631171: Re-implement the 'warnings' module in C (the
8537 original Python code has been kept as backup). This will allow for
8538 using the 'warning's machinery in such places as the parser where
8539 use of pure Python code is not possible. Both the ``showarning()``
8540 and ``formatwarning()`` gain an optional 'line' argument which is
8541 not called by default for backwards-compatibility reasons. Setting
8542 ``warnings.showwarning()`` to an implementation that lacks support
8543 for the ``line`` argument will raise a DeprecationWarning.

8567
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008568- The getpass module has been improved on Unix. It now uses /dev/tty
8569 by default and uses stderr instead of stdout. A GetPassWarning is
8570 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008606- Issue #2550: The approach used by client/server code for obtaining
8607 ports to listen on in network-oriented tests has been refined in an
8608 effort to facilitate running multiple instances of the entire
8609 regression test suite in parallel without issue.
8610 test_support.bind_port() has been fixed such that it will always
8611 return a unique port -- which wasn't always the case with the
8612 previous implementation, especially if socket options had been set
8613 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8614 new implementation of bind_port() will actually raise an exception
8615 if it is passed an AF_INET/SOCK_STREAM socket with either the
8616 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8617 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8618 the socket it's been passed. This currently only applies to
8619 Windows. This option prevents any other sockets from binding to the
8620 host/port we've bound to, thus removing the possibility of the
8621 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8622 when a second SOCK_STREAM socket binds and accepts to a host/port
8623 that's already been bound by another socket. The optional preferred
8624 port parameter to bind_port() has been removed. Under no
8625 circumstances should tests be hard coding ports!
8626
8627 test_support.find_unused_port() has also been introduced, which will
8628 pass a temporary socket object to bind_port() in order to obtain an
8629 unused port. The temporary socket object is then closed and
8630 deleted, and the port is returned. This method should only be used
8631 for obtaining an unused port in order to pass to an external program
8632 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8633 a parameter to a server-oriented class that doesn't give you direct
8634 access to the underlying socket used.
8635
8636 Finally, test_support.HOST has been introduced, which should be used
8637 for the host argument of any relevant socket calls (i.e. bind and
8638 connect).

8643 test_asynchat and test_socket_ssl.
8644
Georg Brandl3ee81df2008-05-17 18:14:43 +00008645 It is now possible for multiple instances of the regression test
8646 suite to run in parallel without issue.

8913-----------------
8914
Fred Drakea8ee94b2008-03-01 02:45:07 +00008915- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008916 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008917
Georg Brandlad61bc82008-02-23 15:11:18 +00008918- Issue #2067: file.__exit__() now calls subclasses' close() method.
8919
8920- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008921
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008922- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008923 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008924
Eric Smitha73fbe72008-02-23 03:09:44 +00008925- Added the future_builtins module, which contains hex() and oct().
8926 These are the PEP 3127 version of these functions, designed to be
8927 compatible with the hex() and oct() builtins from Python 3.0. They
8928 differ slightly in their output formats from the existing, unchanged
8929 Python 2.6 builtins. The expected usage of the future_builtins
8930 module is:
8931 from future_builtins import hex, oct
8932
Eric Smith7ef40bf2008-02-20 23:34:22 +00008933- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8934 exponents for exponents with absolute value < 100. Follows C99
8935 standard. This is a change on Windows, which would use 3 digits.
8936 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8937 so that any alterations it does to the resulting string will be
8938 available in stringlib/formatter.h (for float.__format__).
8939
Eric Smith5a3c1352008-02-19 13:21:56 +00008940- Implemented PEP 3101, Advanced String Formatting. This adds a new
8941 builtin format(); a format() method for str and unicode; a
8942 __format__() method to object, str, unicode, int, long, float, and
8943 datetime; the class string.Formatter; and the C API
8944 PyObject_Format().
8945
Georg Brandl3ee81df2008-05-17 18:14:43 +00008946- Fixed several potential crashes, all caused by specially crafted
8947 __del__ methods exploiting objects in temporarily inconsistent
8948 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008949
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008950- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008951 prevent a possible crash: an Abstract Base Class would try to access
8952 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008953
Georg Brandl3ee81df2008-05-17 18:14:43 +00008954- Fixed repr() and str() of complex numbers with infinity or nan as
8955 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008956
Georg Brandl3ee81df2008-05-17 18:14:43 +00008957- Clear all free lists during a gc.collect() of the highest generation
8958 in order to allow pymalloc to free more arenas. Python may give back
8959 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008960
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961- Issue #2045: Fix an infinite recursion triggered when printing a
8962 subclass of collections.defaultdict, if its default_factory is set
8963 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008964
Christian Heimesf75dbef2008-02-08 00:11:31 +00008965- Fixed a minor memory leak in dictobject.c. The content of the free
8966 list was not freed on interpreter shutdown.
8967
Georg Brandl21e99f42010-03-07 15:23:59 +00008968- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008969 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008970
Georg Brandl3ee81df2008-05-17 18:14:43 +00008971- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8972 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008973 to compact the internal free lists of pre-allocted ints and floats.
8974
Georg Brandl3ee81df2008-05-17 18:14:43 +00008975- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8976 calls. Python expected the return type int but the fork familie
8977 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008978
Georg Brandl3ee81df2008-05-17 18:14:43 +00008979- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8980 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008981
Georg Brandl3ee81df2008-05-17 18:14:43 +00008982- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8983 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008984
Georg Brandl3ee81df2008-05-17 18:14:43 +00008985- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8986 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008987
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8989 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008990
Georg Brandl3ee81df2008-05-17 18:14:43 +00008991- Patch #1473257: generator objects gain a gi_code attribute. This is
8992 the same object as the func_code attribute of the function that
8993 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008994
Georg Brandl3ee81df2008-05-17 18:14:43 +00008995- Issue #1920: "while 0" statements were completely removed by the
8996 compiler, even in the presence of an "else" clause, which is
8997 supposed to be run when the condition is false. Now the compiler
8998 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008999
Guido van Rossumeead05f2008-01-24 18:21:02 +00009000- A few crashers fixed: weakref_in_del.py (issue #1377858);
9001 loosing_dict_ref.py (issue #1303614, test67.py);
9002 borrowed_ref_[34].py (not in tracker).
9003
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009004- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009005 suppressed while an extension is loaded by calling SetErrorMode in
9006 dynload_win.c. The error is still reported properly.
9007
Georg Brandl3ee81df2008-05-17 18:14:43 +00009008- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009009 several extension methods and modules do not work without unicode
9010 support.
9011
Georg Brandl26543b12008-01-21 18:36:51 +00009012- Issue #1882: when compiling code from a string, encoding cookies in the
9013 second line of code were not always recognized correctly.
9014
Georg Brandl14404b62008-01-19 19:27:05 +00009015- Issue #1679: "0x" was taken as a valid integer literal.
9016
Georg Brandl6caad7d2008-01-26 14:19:22 +00009017- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009018 added.
9019
Christian Heimesc94e2b52008-01-14 04:13:37 +00009020- sys.float_info / PyFloat_GetInfo: The floating point information
9021 object was converted from a dict to a specialized structseq object.
9022
Georg Brandl3ee81df2008-05-17 18:14:43 +00009023- Patch #1816: Added sys.flags structseq. It exposes the status of
9024 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009025
Georg Brandl3ee81df2008-05-17 18:14:43 +00009026- Objects/structseq.c: Implemented new structseq representation. The
9027 patch makes structseqs (e.g. the return value of os.stat) more
9028 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009029
Georg Brandl3ee81df2008-05-17 18:14:43 +00009030- Patch #1700288: added a type attribute cache that caches method
9031 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009032
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009033- Bug #1776: __import__() no longer accepts filenames on any platform.
9034 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009035
Georg Brandlaed6c662008-01-07 17:25:53 +00009036- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9037
Georg Brandl3ee81df2008-05-17 18:14:43 +00009038- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9039 envvar and sys.dont_write_bytecode attribute. All these can be set
9040 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009041
Georg Brandl3ee81df2008-05-17 18:14:43 +00009042- Improve some exception messages when Windows fails to load an
9043 extension module. Now we get for example '%1 is not a valid Win32
9044 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009045
Georg Brandl3ee81df2008-05-17 18:14:43 +00009046- Bug #1481296: Fixed long(float('nan')) != 0L.

9049 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009050
Christian Heimes0a8143f2007-12-18 23:22:54 +00009051- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009052 and INF. float("nan"), float("inf") and float("-inf") now work on
9053 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009054
Georg Brandl3ee81df2008-05-17 18:14:43 +00009055- Compiler now generates simpler and faster code for dictionary
9056 literals. The oparg for BUILD_MAP now indicates an estimated
9057 dictionary size. There is a new opcode, STORE_MAP, for adding
9058 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009059
Georg Brandl3ee81df2008-05-17 18:14:43 +00009060- Issue #1638: %zd configure test fails on Linux.

9090 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009091
Georg Brandl3ee81df2008-05-17 18:14:43 +00009092- Issue #1265: Fix a problem with sys.settrace, if the tracing
9093 function uses a generator expression when at the same time the
9094 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009095
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009096- sets and frozensets now have an isdisjoint() method.
9097
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009098- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00009100- Fix warnings found by the new version of the Coverity checker.
9101
Georg Brandl21e99f42010-03-07 15:23:59 +00009102- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009103 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9104 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009105
Georg Brandl3ee81df2008-05-17 18:14:43 +00009106- Issue #1686386: Tuple's tp_repr did not take into account the
9107 possibility of having a self-referential tuple, which is possible
9108 from C code. Nor did object's tp_str consider that a type's tp_str
9109 could do something that could lead to an inifinite recursion.
9110 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9111 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009112
Georg Brandl3ee81df2008-05-17 18:14:43 +00009113- Issue #1164: It was possible to trigger deadlock when using the
9114 'print' statement to write to a file since the GIL was not released
9115 as needed. Now PyObject_Print() does the right thing along with
9116 various tp_print implementations of the built-in types and those in
9117 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009118
Georg Brandl3ee81df2008-05-17 18:14:43 +00009119- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009126- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009127 PyObject_Call() never calling back out to Python code to trigger
9128 recursion depth updates/checks. Required the creation of a static
9129 RuntimeError instance in case normalizing an exception put the
9130 recursion check value past its limit. Fixes crashers
9131 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00009146- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009147 __*__ attributes. (Some already existed, e.g., __doc__ and
9148 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009149
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009150- Add -3 option to the interpreter to warn about features that are

9154 calls.
9155
Collin Winter62903052007-05-18 23:11:24 +00009156- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157 "except E as target:". This is to provide forwards compatibility
9158 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009166 setting a plain string, ie don't expand to single letter identifiers.
9167
Raymond Hettinger13936692007-04-11 18:40:58 +00009168- Request #1191699: Slices can now be pickled.
9169
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009170- Request #1193128: str.translate() now allows a None argument for

9178
Guido van Rossum143b5642007-03-23 04:58:42 +00009179- Bug #1683368: The object.__init__() and object.__new__() methods are
9180 now stricter in rejecting excess arguments. The only time when
9181 either allows excess arguments is when it is not overridden and the
9182 other one is. For backwards compatibility, when both are
9183 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009184 warning later). Also, type.__init__() insists on the same signature
9185 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009187- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9188 object to complex using its __complex__() method before falling back
9189 to the __float__() method. Therefore, the functions in the cmath
9190 module now can operate on objects that define a __complex__()
9191 method.

9208
Georg Brandl7b9c5552007-03-12 14:30:05 +00009209- Bug #1678647: write a newline after printing an exception in any
9210 case, even when converting the value to a string failed.
9211
Georg Brandl871f1bc2007-03-12 13:17:36 +00009212- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213 its argument, if it exists. If not, it will work like before. This
9214 allows customizing the output of dir() in the presence of a
9215 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009216
Collin Winter276887b2007-03-12 16:11:39 +00009217- Patch #922167: Python no longer segfaults when faced with infinitely

9224 parthensized forms. This means complex(repr(x)) now works instead of
9225 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009226
Georg Brandlaa2321b2007-03-07 00:40:28 +00009227- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009228 makes the filenames the warning module prints much more sensible
9229 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009230

Georg Brandl0fca97a2007-03-05 22:28:08 +00009242- Patch #1674228: when assigning a slice (old-style), check for the
9243 sq_ass_slice instead of the sq_slice slot.
9244
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245- When printing an unraisable error, don't print exceptions. before

9855 Python would crash instead of raising an error.
9856

9869
Georg Brandl3ee81df2008-05-17 18:14:43 +00009870- unittest now verifies more of its assumptions. In particular,
9871 TestCase and TestSuite subclasses (not instances) are no longer
9872 accepted in TestSuite.addTest(). This should cause no
9873 incompatibility since it never made sense with ordinary subclasses
9874 -- the failure just occurred later, with a more cumbersome
9875 exception.

10144 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010145
Georg Brandl3ee81df2008-05-17 18:14:43 +000010146- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010155- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010156 that the SMTP.starttls() caller no longer needs to call ehlo()
10157 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010158 does not claim to support starttls. Adds the
10159 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010202- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010203 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +000010258 time so that opening a database previously created with the DB_DUP
10259 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10260 opens. Specifically: dictionary assignment to a DB object will
10261 replace all values for a given key when the database allows
10262 duplicate values. DB users should use DB.put(k, v) when they want
10263 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010264

10270 characters with ASCII value less than 32. Also, it correctly quotes
10271 dots only if they occur on a single line, as opposed to the previous
10272 behavior of quoting dots if they are the second character of any
10273 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010274

10601-----
10602
Georg Brandl3ee81df2008-05-17 18:14:43 +000010603- Unified naming convention for free lists and their limits. All free
10604 lists in Object/ are named ``free_list``, the counter ``numfree``
10605 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10606 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010607
Georg Brandl3ee81df2008-05-17 18:14:43 +000010608- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10609 to ``PyTuple_SetItem``, it can be used to populate a brand new
10610 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010611
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010612- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

10615 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10616 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010617
10618- Patch #1720595: add T_BOOL to the range of structmember types.
10619
10620- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10621 ``PyFloat_GetInfo()`` to the float API.
10622
Georg Brandl3ee81df2008-05-17 18:14:43 +000010623- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10624 of w# format code incorrectly truncated the length to an int, even
10625 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10626 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010627
Georg Brandl3ee81df2008-05-17 18:14:43 +000010628- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10629 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010631- PEP 3123: Provide forward compatibility with Python 3.0, while
10632 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10633 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010634
Georg Brandl3ee81df2008-05-17 18:14:43 +000010635- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10636 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010637
10638- Patch #1733960: Allow T_LONGLONG to accept ints.

10645
10646- Fix some leftovers from the conversion from int to Py_ssize_t
10647 (relevant to strings and sequences of more than 2**31 items).
10648
10649- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10650 outside of pystate.c and should not be necessary.
10651
Georg Brandl3ee81df2008-05-17 18:14:43 +000010652- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10653 absolute imports. In earlier versions they might have used relative
10654 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010655
Georg Brandl3ee81df2008-05-17 18:14:43 +000010656- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10657 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010658
Georg Brandl3ee81df2008-05-17 18:14:43 +000010659- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010665- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10666 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10667 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10668 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010669
Georg Brandl3ee81df2008-05-17 18:14:43 +000010670- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010682- Removed the macfs module. It had been deprecated since Python 2.5.
10683 This lead to the deprecation of macostools.touched() as it relied
10684 solely on macfs and was a no-op under OS X.
