Ned Deily87e82bb2011-06-28 19:52:59 -070021- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
22 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
23 interpreter process. This could cause failures in non-Distutils subprocesses
24 and was unreliable since tests or user programs could modify the interpreter
25 environment after Distutils set it. Instead, have Distutils set the the
26 deployment target only in the environment of each build subprocess. It is
27 still possible to globally override the default by setting
28 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
29 greater or equal to the default value, the value with which the interpreter
30 was built.
31
Raymond Hettinger2c316a32011-06-25 17:14:53 +020032- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

R David Murrayf1138bb2011-06-17 22:23:04 -040038- Issue #11700: mailbox proxy object close methods can now be called multiple
39 times without error, and _ProxyFile now closes the wrapped file.
40
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020041- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
42 connection if its getresponse() method fails with a socket error. Patch
43 written by Ezio Melotti.
44
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050045- Issue #9284: Allow inspect.findsource() to find the source of doctest

Raymond Hettinger19b851d2011-06-01 18:21:42 -070058- sys.setcheckinterval() now updates the current ticker count as well as updating
59 the check interval, so if the user decreases the check interval, the ticker
60 doesn't have to wind down to zero from the old starting point before the new
61 interval takes effect. And if the user increases the interval, it makes sure
62 the new limit takes effect right away rather have an early task switch before
63 recognizing the new interval.
64
Victor Stinner776e69b2011-06-01 01:03:00 +020065- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001345- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1346 start byte and the continuation byte(s) are now considered invalid, instead
1347 of the number of bytes specified by the start byte.
1348 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1349 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1350 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001359- Issue #8748: Fix two issues with comparisons between complex and integer
1360 objects. (1) The comparison could incorrectly return True in some cases
1361 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1362 (2) The comparison raised an OverflowError for large integers, leading
1363 to unpredictable exceptions when combining integers and complex objects
1364 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001366- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001503- Issue #1533: Fix inconsistency in range function argument processing: any
1504 non-float non-integer argument is now converted to an integer (if possible)
1505 using its __int__ method. Previously, only small arguments were treated this
1506 way; larger arguments (those whose __int__ was outside the range of a C long)
1507 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001515 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001516 benefit compared to the dynamic memory allocation fallback. Patch by

1543 inheritance with the underlying socket object. The cheap inheritance has been
1544 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001557- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1558 operation raises multiple signals and more than one of those signals is
1559 trapped, the specification determines the order in which the signals should be
1560 handled. In many cases this order wasn't being followed, leading to the wrong
1561 Python exception being raised.

1728Core and Builtins
1729-----------------
1730
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001731- Issue #7301: Add environment variable $PYTHONWARNINGS.
1732
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001733- Issue #8329: Don't return the same lists from select.select when no fds are
1734 changed.
1735
Georg Brandlfee0f442010-05-22 21:26:21 +00001736- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001737 on 64-bit machines. The shift count for either left or right shift is
1738 permitted to be up to sys.maxsize.
1739
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001740- Ensure that tokenization of identifiers is not affected by locale.
1741
Georg Brandlfee0f442010-05-22 21:26:21 +00001742- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001743
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001744- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1745
Georg Brandlfee0f442010-05-22 21:26:21 +00001746- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1747 with a non-empty format string. This is an effort to future-proof user
1748 code. If a derived class does not currently implement __format__ but later
1749 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001750 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001751 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001752
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001753- Issue #8268: Old-style classes (not just instances) now support weak
1754 references.
1755
Georg Brandlfee0f442010-05-22 21:26:21 +00001756- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1757 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001758
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001759- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00001760
Benjamin Peterson96545892010-03-21 20:21:00 +00001761- Issue #6474: Make error message from passing an inadequate number of keyword
1762 arguments to a function correct.
1763
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001764- Issue #8164: Don't allow lambda functions to have a docstring.
1765
Victor Stinner66644262010-03-10 22:30:19 +00001766- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001767 (SIGINT). If an error occurs while importing the site module, the error is
1768 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001769 module.
1770
Collin Winter001a3952010-03-18 21:54:01 +00001771- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00001776- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1777
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001778- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001779 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1780 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001781
Benjamin Peterson76a23c12010-04-04 23:23:22 +00001782- Issue #8310: Allow dis to examine new style classes.
1783
Georg Brandlfee0f442010-05-22 21:26:21 +00001784- Issue #8257: The Decimal construct now accepts a float instance directly,
1785 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001786
1787 >>> Decimal(1.1)
1788 Decimal('1.100000000000000088817841970012523233890533447265625')
1789
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001790- collections.Counter() now supports a subtract() method.
1791
Georg Brandlfee0f442010-05-22 21:26:21 +00001792- The functools module now has a total_ordering() class decorator to simplify
1793 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001794
Georg Brandlfee0f442010-05-22 21:26:21 +00001795- The functools module also adds cmp_to_key() as a tool to transition old-style
1796 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001797
Georg Brandlfee0f442010-05-22 21:26:21 +00001798- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1799 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001800
Georg Brandlfee0f442010-05-22 21:26:21 +00001801- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1802 InvalidOperation instead of returning False. (Comparisons involving a quiet
1803 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1804 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001805
Georg Brandlfee0f442010-05-22 21:26:21 +00001806- Issue #2531: Comparison operations between floats and Decimal instances now
1807 return a result based on the numeric values of the operands; previously they
1808 returned an arbitrary result based on the relative ordering of id(float) and
1809 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001810
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001811- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001812 argument `-` which tells it to read files to compile from stdin. Each line is
1813 read on demand and the named file is compiled immediately. (Original patch by
1814 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001815
Georg Brandlfee0f442010-05-22 21:26:21 +00001816- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1817 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001819- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1820 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001821 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001822
Georg Brandlfee0f442010-05-22 21:26:21 +00001823- Comparisons using one of <, <=, >, >= between a complex instance and a
1824 Fractions instance now raise TypeError instead of returning True/False. This
1825 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1826 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001827
Michael Foorde6410c52010-03-29 20:04:23 +00001828- Addition of ``WeakSet`` to the ``weakref`` module.

1836
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001837- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001838 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1839 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001840
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001841- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1842 deprecated.
1843
Georg Brandlfee0f442010-05-22 21:26:21 +00001844- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1845 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001846

Georg Brandlfee0f442010-05-22 21:26:21 +00001850- Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names
1851 existing at the same time, causing a Unicode error when configuration code
1852 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001853
Georg Brandlfee0f442010-05-22 21:26:21 +00001854- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1855 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001856
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001857- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1858 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1859 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001860
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001861- Issue #8179: Fix macpath.realpath() on a non-existing path.

1867 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00001868
Matthias Klose8b411682010-03-16 10:48:52 +00001869- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1870 with Tcl/Tk-8.5.

1875 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00001876
Georg Brandlfee0f442010-05-22 21:26:21 +00001877- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001881- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001882 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1883 log file to compute the next rollover time. If the log file does not exist,
1884 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001885
Georg Brandlba83f822010-03-14 09:50:54 +00001886- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

1893
Georg Brandlba83f822010-03-14 09:50:54 +00001894- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1895 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1896 This is a behavior change, so email's minor version number is now bumped, to
1897 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001898

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001925- Issue #8300: When passing a non-integer argument to struct.pack with any
1926 integer format code, struct.pack first attempts to convert the non-integer
1927 using its __index__ method. If that method is non-existent or raises
1928 TypeError it goes on to try the __int__ method, as described below.
1929
Georg Brandlba83f822010-03-14 09:50:54 +00001930- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1931 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1932 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001933 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1934 inconsistent: __int__ was used for some integer codes but not for others, and
1935 the set of integer codes for which it was used differed between native packing
1936 and standard packing.)

2342
Georg Brandlba83f822010-03-14 09:50:54 +00002343- The ``__complex__()`` method is now looked up on the class of instances to
2344 make it consistent with other special methods.

2348
Mark Dickinson1b34d252010-01-01 17:27:30 +00002349- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002350 DeprecationWarning when passed a float argument where an integer was expected.
2351 These functions and methods now raise TypeError instead. The majority of the
2352 effects of this change are in the extension modules, but some core functions
2353 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2354 and many unicode/str methods.

2368 of integers: the result of a/b is now correctly rounded for ints a and b (at
2369 least on IEEE 754 platforms), and in particular does not depend on the
2370 internal representation of a long.

2378
Georg Brandlba83f822010-03-14 09:50:54 +00002379 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002519- Issue #3382: 'F' formatting for float and complex now convert the result to
2520 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2521 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002522
Georg Brandlba83f822010-03-14 09:50:54 +00002523- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2524 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002525
Georg Brandlba83f822010-03-14 09:50:54 +00002526- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2527 1e-100 used to raise OverflowError, but now gives the requested 120
2528 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002529

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002536
Georg Brandlba83f822010-03-14 09:50:54 +00002537- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2538 decimal string that's guaranteed to round back to x under correct rounding
2539 (with round-half-to-even rounding mode). Previously it gave a string based on
2540 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2541 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2542 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002543
Georg Brandlba83f822010-03-14 09:50:54 +00002544- Issue #7117: On almost all platforms: float-to-string and string-to-float
2545 conversions within Python are now correctly rounded. Places these conversions
2546 occur include: str for floats and complex numbers; the float and complex
2547 constructors; old-style and new-style numeric formatting; serialization and
2548 deserialization of floats and complex numbers using marshal, pickle and json;
2549 parsing of float and imaginary literals in Python code; Decimal-to-float
2550 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002551
Georg Brandlba83f822010-03-14 09:50:54 +00002552 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2553 providing correctly-rounded strtod and dtoa C functions. This code is
2554 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2555 the C compiler. There may be a small number of platforms on which correct
2556 operation of this code cannot be guaranteed, so the code is not used: notably,
2557 this applies to platforms where the C double format is not IEEE 754 binary64,
2558 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2559 and Python's configure script is unable to determine how to change the FPU
2560 precision. On these platforms conversions use the platform strtod and dtoa,
2561 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002562
Georg Brandlba83f822010-03-14 09:50:54 +00002563- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2564 uses the correctly-rounded string <-> float conversions described above (when
2565 available), and so produces correctly rounded results that will display nicely
2566 under the float repr. There are two related small changes: (1) round now
2567 accepts any class with an ``__index__()`` method for its second argument (but
2568 no longer accepts floats for the second argument), and (2) an excessively
2569 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2570 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002574- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002712
Georg Brandlba83f822010-03-14 09:50:54 +00002713 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2714 (2) parsing of strings representing infinities and nans was locale aware; and
2715 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002717- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2718 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2719 but with at least one decimal point and with a default precision
2720 of 12. Previously, the behavior the same but with a default precision of 6.
2721 This more closely matches ``str()``, and reduces surprises when adding
2722 alignment flags to the empty presentation type. This also affects the new
2723 complex.__format__ in the same way.
2724
2725- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2726 classtype's, even if it was None. property now inserts the __doc__ into the

2797 internal representation of integers, for performance reasons. Base 2**30 is
2798 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00002886- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002887 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002888
Skip Montanarof205c132008-12-23 03:30:15 +00002889- Added test case to ensure attempts to read from a file opened for writing
2890 fail.
2891
Georg Brandlba83f822010-03-14 09:50:54 +00002892- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2893 elapsed times, not only when some objects are uncollectable/unreachable.
2894 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00002895
Mark Dickinson1a707982008-12-17 16:14:37 +00002896- Issue #3439: Add a bit_length method to int and long.
2897
Georg Brandlba83f822010-03-14 09:50:54 +00002898- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
2899 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00002900
Georg Brandlba83f822010-03-14 09:50:54 +00002901- Issue #4597: Fixed exception handling when the __exit__ function of a context
2902 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002903
Georg Brandlba83f822010-03-14 09:50:54 +00002904- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002905
Georg Brandlba83f822010-03-14 09:50:54 +00002906- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2907 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2908 instances. On a typical machine this saves 3 bytes of memory (on average) per
2909 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002910
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002911- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2912 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2913 instead of throwing a MemoryError.
2914
Georg Brandlba83f822010-03-14 09:50:54 +00002915- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2916 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002917
Benjamin Petersonc078f922008-11-21 22:27:24 +00002918- Issue #4367: Python would segfault during compiling when the unicodedata
2919 module couldn't be imported and \N escapes were present.
2920
Georg Brandlba83f822010-03-14 09:50:54 +00002921- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2922 file objects with closefd=False. The file descriptor is still kept open but
2923 the file object behaves like a closed file. The ``FileIO`` object also got a
2924 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002925
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002926- Issue #4348: Some bytearray methods returned that didn't cause any change to
2927 the bytearray, returned the same bytearray instead of a copy.
2928
Georg Brandlba83f822010-03-14 09:50:54 +00002929- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00002931- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2932
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002933- Issue #4048: The parser module now correctly validates relative imports.
2934
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002935- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2936 exec statement.
2937
Georg Brandlba83f822010-03-14 09:50:54 +00002938- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2939 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002940
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002941- Issue #4209: Enabling unicode_literals and the print_function in the same
2942 __future__ import didn't work.
2943
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002944- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002945 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002946
Georg Brandlba83f822010-03-14 09:50:54 +00002947- On windows, ``os.chdir()`` given unicode was not working if
2948 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2949 this code path is really executed because I cannot move to such directory on
2950 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002951
Georg Brandlba83f822010-03-14 09:50:54 +00002952- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2953 element is temporarily replaced with an equivalent frozenset. But the
2954 eventual KeyError would always report the empty ``frozenset()`` as the missing
2955 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002956
Georg Brandlba83f822010-03-14 09:50:54 +00002957- Issue #4509: Various issues surrounding resize of bytearray objects to which
2958 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002959

2963
Gregory P. Smithae91d092009-03-02 05:13:57 +00002964- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2965
Georg Brandlba83f822010-03-14 09:50:54 +00002966- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2967 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002968
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002969- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2970 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002971
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002972- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2973 returned them on 64bit platforms.
2974
Walter Dörwalded960ac2009-05-03 22:36:33 +00002975- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2976 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2977 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2978 of using the replace error handler in PyUnicode_DecodeUTF8().
2979
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002980- Issue #3739: The unicode-internal encoder now reports the number of characters
2981 consumed like any other encoder (instead of the number of bytes).
2982
Georg Brandlba83f822010-03-14 09:50:54 +00002983- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2984 allocator will be automatically disabled when running under Valgrind. This
2985 gives improved memory leak detection when running under Valgrind, while taking
2986 advantage of pymalloc at other times.

4152 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4153 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4154 neither __int__ nor __long__, TypeError used to be raised (with a
4155 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4156 struct.error in other cases.

4159 argument with an __int__ method can be packed, but use of this feature

Georg Brandlba83f822010-03-14 09:50:54 +00004248- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4249 should cause a test to be skipped are now done using import_module from test
4250 support, which does the conversion.

4352
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004353- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4354 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4355 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4356 ``printf`` function, whereas PyString_FromFormat has an independent
4357 implementation and uses "%zd" on all platforms for size_t values.
4358 This makes a difference on win64, where ``printf`` needs "%Id" to display
4359 64bit values.

4365 object; previously an int would be returned for small values. the __long__
4366 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004376 was correctly parsed but parsing of subsequent arguments failed.
4377
Vinay Sajip35e3b032008-09-01 14:33:59 +00004378- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004379 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4380 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4381 when given a tuple of classes as second argument, were looking up
4382 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4383 type object.
4384
Neal Norwitz18aa3882008-08-24 05:04:52 +00004385- Fix crashes on memory allocation failure found with failmalloc.

4528-----------------
4529
Guido van Rossumf8402962008-08-20 15:01:50 +00004530- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4531 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4532 extensions do not automatically benefit from the class attribute
4533 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4534 to their tp_flags field if they care. This is a backwards
4535 compatibility feature; in 3.0, all types will use the cache by
4536 default.
4537
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004538- Keyword arguments can now follow starred arguments. (``f(a, *args,
4539 keyword=23)`` is now valid syntax.)
4540
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004541- ctypes function pointers that are COM methods have a boolean True

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004544- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4545 by denying s# to parse objects that have a releasebuffer procedure,
4546 and introducing s*.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004551- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4552 ValueError consistently across platforms.
4553
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004554- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4555 (64bit Unix, for example), unichr() would truncate its argument and return
4556 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4557
Neal Norwitze7d8be82008-07-31 17:17:14 +00004558- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004560- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4561 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4562
Antoine Pitrou92f82162008-07-25 22:22:08 +00004563- Issue #1819: function calls with several named parameters are now on
4564 average 35% faster (as measured by pybench).
4565
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004566- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4567 the python debugger steps into a class statement: the free variables (local
4568 variables defined in an outer scope) would be deleted from the outer scope.
4569
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004570- Issue #2620: Overflow checking when allocating or reallocating memory
4571 was not always being done properly in some python types and extension
4572 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4573 all been updated to perform better checks and places in the code that
4574 would previously leak memory on the error path when such an allocation
4575 failed have been fixed.

4581
Benjamin Petersone977ad42008-08-20 01:42:01 +00004582- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4583 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4584
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004585- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4586 version reported by these tools does not necessarily follow the python
4587 version numbering scheme, so the module is less strict when parsing it.
4588
Nick Coghlanf70385a2008-08-18 12:42:46 +00004589- Issue #2235: Added Py3k warnings for types which will become unhashable
4590 under the stricter __hash__ inheritance rules in 3.0. Several types
4591 which did not meet the rules for hash invariants and were already
4592 unhashable in 3.0 have now been explicitly flagged as unhashable in
4593 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4594 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4595
Brett Cannon88f801d2008-08-18 00:46:22 +00004596- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00004627- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4628 since mimetools itself is deprecated. Because modules are cached, all
4629 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4630

4640 a MemoryError rather than silently stop the iteration.
4641
Guido van Rossum59ce9012008-08-09 14:55:34 +00004642- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4643 to _sre.compile() will now be rejected. This should not affect anybody
4644 since the re.compile() function never generates invalid re-bytecode.
4645
Skip Montanaroa032bf42008-08-08 22:52:51 +00004646- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

4648 it wasn't initialized during instantiation.
4649
Brett Cannon3aa2a492008-08-06 22:28:09 +00004650- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4651 the reload() built-in has been removed.
4652
Brett Cannon7e30b672008-08-04 21:52:25 +00004653- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00004665 asking for a specific length. This problem only affected files opened
4666 using the new "io" module, not the built-in open() function.

4692 file name rather than a ZipInfo instance, so files are extracted with
4693 mode 0600 rather than 000 under Unix.
4694
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004695- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4696 argument in python 2.5, this broke code that subclassed Popen to include its

4708 interaction with the tp_hash slot (added in 2.6b2) are now documented
4709
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004710- Issue #643841: The language reference now provides more detailed
4711 coverage of the lookup process for special methods. The disclaimers
4712 regarding lack of coverage of new-style classes have also been
4713 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004721Core and Builtins
4722-----------------
4723
Georg Brandl3e483f62008-07-16 22:57:41 +00004724- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4725 its methods now allow for items objects that can be converted to
4726 an integer using operator.index().
4727
Mark Dickinson64b7e502008-07-16 09:40:03 +00004728- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4729 produced a ValueError instead of giving the correct float.
4730
Eric Smitha5fa5a22008-07-16 00:11:49 +00004731- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4732 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4733
Mark Dickinson7103aa42008-07-15 19:08:33 +00004734- Issue #3008: the float type has a new instance method 'float.hex'
4735 and a new class method 'float.fromhex' to convert floating-point
4736 numbers to and from hexadecimal strings, respectively.
4737
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004738- Issue #2235: __hash__ is once again inherited by default. To allow
4739 collections.Hashable to remain meaningful in the presence of the
4740 default hash implementation (object.__hash__), it is now possible
4741 to explicit block inheritance of hash by setting __hash__=None at
4742 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4743 level.
4744
Nick Coghlanb028f502008-07-13 14:52:36 +00004745- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4746 the parent module cannot be found while performing an absolute import.
4747 This means that an incorrectly defined __package__ attribute will
4748 now only prevent relative imports in that module rather than causing
4749 all imports from that module to fail.
4750
Nick Coghlan14ff9942008-07-08 14:21:42 +00004751- Issue #2517: Allow unicode messages in Exceptions again by correctly
4752 bypassing the instance dictionary when looking up __unicode__ on
4753 new-style classes.
4754
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004755- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4756 set to a custom object whose write() method happens to install
4757 another file in sys.stdout.
4758
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004759- Issue #3088: Corrected a race condition in classes derived from
4760 threading.local: the first member set by a thread could be saved in
4761 another thread's dictionary.
4762
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004763- Issue #3004: Minor change to slice.indices(): the start and stop
4764 arguments are now treated identically, making the behaviour easier
4765 to describe and understand. For example, slice(None, -10,
4766 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4767 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4768 10, -1).
4769
Georg Brandl278fc502008-07-19 12:46:12 +00004770- Issue #3219: Calling a function with repeated keyword arguments,
4771 f(a=2, a=23), would not cause a syntax error. This was a regression
4772 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004773
Georg Brandl278fc502008-07-19 12:46:12 +00004774- Issue #2862: Make int and float freelist management consistent with
4775 other freelists. Changes their CompactFreeList apis into
4776 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004777

4780
Thomas Heller57adf222008-08-14 19:10:48 +00004781- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4782 api functions without holding the GIL, which could lead to a fatal
4783 error when they failed.
4784
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004785- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4794 ForkingPickler.register() to resolve conflict with ctypes.
4795
Vinay Sajip51e65192008-07-18 09:01:10 +00004796- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004798- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4799 a valid dlerror() message.
4800
Thomas Heller2bad6572008-07-15 17:19:50 +00004801- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4802 incomplete structure was created.
4803
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004804- Issue #3339: dummy_thread.acquire() should not return None.

4807
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004808- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004809
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004810- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4811 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004812 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004813 content-length. The problem had been corrected in the 2.4 branch, but never
4814 merged into trunk.
4815
Georg Brandle78fbcc2008-07-05 10:13:36 +00004816- Issue #2663: add filtering capability to shutil.copytree().

5221 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005222 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005223
5224 This is controlled by the configure argument ``--with-universal-archs``:
5225
5226 - ``--with-universal-archs=all``: install 4-way universal
5227
5228 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5229
5230 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5231
5232 This option should be used in combination with ``--enable-universalsdk=``.
5233
5234 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 +00005284- Issue #1631171: Re-implement the 'warnings' module in C (the
5285 original Python code has been kept as backup). This will allow for
5286 using the 'warning's machinery in such places as the parser where
5287 use of pure Python code is not possible. Both the ``showarning()``
5288 and ``formatwarning()`` gain an optional 'line' argument which is
5289 not called by default for backwards-compatibility reasons. Setting
5290 ``warnings.showwarning()`` to an implementation that lacks support
5291 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005354- Issue #2550: The approach used by client/server code for obtaining
5355 ports to listen on in network-oriented tests has been refined in an
5356 effort to facilitate running multiple instances of the entire
5357 regression test suite in parallel without issue.
5358 test_support.bind_port() has been fixed such that it will always
5359 return a unique port -- which wasn't always the case with the
5360 previous implementation, especially if socket options had been set
5361 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5362 new implementation of bind_port() will actually raise an exception
5363 if it is passed an AF_INET/SOCK_STREAM socket with either the
5364 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5365 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5366 the socket it's been passed. This currently only applies to
5367 Windows. This option prevents any other sockets from binding to the
5368 host/port we've bound to, thus removing the possibility of the
5369 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5370 when a second SOCK_STREAM socket binds and accepts to a host/port
5371 that's already been bound by another socket. The optional preferred
5372 port parameter to bind_port() has been removed. Under no
5373 circumstances should tests be hard coding ports!
5374
5375 test_support.find_unused_port() has also been introduced, which will
5376 pass a temporary socket object to bind_port() in order to obtain an
5377 unused port. The temporary socket object is then closed and
5378 deleted, and the port is returned. This method should only be used
5379 for obtaining an unused port in order to pass to an external program
5380 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5381 a parameter to a server-oriented class that doesn't give you direct
5382 access to the underlying socket used.
5383
5384 Finally, test_support.HOST has been introduced, which should be used
5385 for the host argument of any relevant socket calls (i.e. bind and
5386 connect).

5662
Fred Drakea8ee94b2008-03-01 02:45:07 +00005663- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005664 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005665
Georg Brandlad61bc82008-02-23 15:11:18 +00005666- Issue #2067: file.__exit__() now calls subclasses' close() method.
5667
5668- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005669
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005670- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005671 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005672
Eric Smitha73fbe72008-02-23 03:09:44 +00005673- Added the future_builtins module, which contains hex() and oct().
5674 These are the PEP 3127 version of these functions, designed to be
5675 compatible with the hex() and oct() builtins from Python 3.0. They
5676 differ slightly in their output formats from the existing, unchanged
5677 Python 2.6 builtins. The expected usage of the future_builtins
5678 module is:
5679 from future_builtins import hex, oct
5680
Eric Smith7ef40bf2008-02-20 23:34:22 +00005681- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5682 exponents for exponents with absolute value < 100. Follows C99
5683 standard. This is a change on Windows, which would use 3 digits.
5684 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5685 so that any alterations it does to the resulting string will be
5686 available in stringlib/formatter.h (for float.__format__).
5687
Eric Smith5a3c1352008-02-19 13:21:56 +00005688- Implemented PEP 3101, Advanced String Formatting. This adds a new
5689 builtin format(); a format() method for str and unicode; a
5690 __format__() method to object, str, unicode, int, long, float, and
5691 datetime; the class string.Formatter; and the C API
5692 PyObject_Format().
5693
Georg Brandl3ee81df2008-05-17 18:14:43 +00005694- Fixed several potential crashes, all caused by specially crafted
5695 __del__ methods exploiting objects in temporarily inconsistent
5696 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005697
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005698- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699 prevent a possible crash: an Abstract Base Class would try to access
5700 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005701
Georg Brandl3ee81df2008-05-17 18:14:43 +00005702- Fixed repr() and str() of complex numbers with infinity or nan as
5703 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005704
Georg Brandl3ee81df2008-05-17 18:14:43 +00005705- Clear all free lists during a gc.collect() of the highest generation
5706 in order to allow pymalloc to free more arenas. Python may give back
5707 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005708
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709- Issue #2045: Fix an infinite recursion triggered when printing a
5710 subclass of collections.defaultdict, if its default_factory is set
5711 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005712
Christian Heimesf75dbef2008-02-08 00:11:31 +00005713- Fixed a minor memory leak in dictobject.c. The content of the free
5714 list was not freed on interpreter shutdown.
5715
Georg Brandl21e99f42010-03-07 15:23:59 +00005716- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005717 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005718
Georg Brandl3ee81df2008-05-17 18:14:43 +00005719- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5720 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005721 to compact the internal free lists of pre-allocted ints and floats.
5722
Georg Brandl3ee81df2008-05-17 18:14:43 +00005723- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5724 calls. Python expected the return type int but the fork familie
5725 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005726
Georg Brandl3ee81df2008-05-17 18:14:43 +00005727- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5728 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005729
Georg Brandl3ee81df2008-05-17 18:14:43 +00005730- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5731 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005732
Georg Brandl3ee81df2008-05-17 18:14:43 +00005733- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5734 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005735
Georg Brandl3ee81df2008-05-17 18:14:43 +00005736- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5737 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Patch #1473257: generator objects gain a gi_code attribute. This is
5740 the same object as the func_code attribute of the function that
5741 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005742
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Issue #1920: "while 0" statements were completely removed by the
5744 compiler, even in the presence of an "else" clause, which is
5745 supposed to be run when the condition is false. Now the compiler
5746 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005747
Guido van Rossumeead05f2008-01-24 18:21:02 +00005748- A few crashers fixed: weakref_in_del.py (issue #1377858);
5749 loosing_dict_ref.py (issue #1303614, test67.py);
5750 borrowed_ref_[34].py (not in tracker).
5751
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005752- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005753 suppressed while an extension is loaded by calling SetErrorMode in
5754 dynload_win.c. The error is still reported properly.
5755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005757 several extension methods and modules do not work without unicode
5758 support.
5759
Georg Brandl26543b12008-01-21 18:36:51 +00005760- Issue #1882: when compiling code from a string, encoding cookies in the
5761 second line of code were not always recognized correctly.
5762
Georg Brandl14404b62008-01-19 19:27:05 +00005763- Issue #1679: "0x" was taken as a valid integer literal.
5764
Georg Brandl6caad7d2008-01-26 14:19:22 +00005765- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005766 added.
5767
Christian Heimesc94e2b52008-01-14 04:13:37 +00005768- sys.float_info / PyFloat_GetInfo: The floating point information
5769 object was converted from a dict to a specialized structseq object.
5770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Patch #1816: Added sys.flags structseq. It exposes the status of
5772 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005773
Georg Brandl3ee81df2008-05-17 18:14:43 +00005774- Objects/structseq.c: Implemented new structseq representation. The
5775 patch makes structseqs (e.g. the return value of os.stat) more
5776 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005777
Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Patch #1700288: added a type attribute cache that caches method
5779 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005780
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005781- Bug #1776: __import__() no longer accepts filenames on any platform.
5782 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005783
Georg Brandlaed6c662008-01-07 17:25:53 +00005784- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5785
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5787 envvar and sys.dont_write_bytecode attribute. All these can be set
5788 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005789
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- Improve some exception messages when Windows fails to load an
5791 extension module. Now we get for example '%1 is not a valid Win32
5792 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005796- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5797 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005798
Christian Heimes0a8143f2007-12-18 23:22:54 +00005799- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005800 and INF. float("nan"), float("inf") and float("-inf") now work on
5801 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005802
Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Compiler now generates simpler and faster code for dictionary
5804 literals. The oparg for BUILD_MAP now indicates an estimated
5805 dictionary size. There is a new opcode, STORE_MAP, for adding
5806 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Issue #1638: %zd configure test fails on Linux.

5818
Nick Coghlanef01d822007-12-03 12:55:17 +00005819- PEP 366: Allow explicit relative imports when executing modules
5820 inside packages with the -m switch via a new module level
5821 __package__ attribute.
5822
Georg Brandl3ee81df2008-05-17 18:14:43 +00005823- Issue #1402: Fix a crash on exit, when another thread is still
5824 running, and if the deallocation of its frames somehow calls the
5825 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005826

Georg Brandl3ee81df2008-05-17 18:14:43 +00005840- Issue #1265: Fix a problem with sys.settrace, if the tracing
5841 function uses a generator expression when at the same time the
5842 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005843
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005844- sets and frozensets now have an isdisjoint() method.
5845
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005846- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00005848- Fix warnings found by the new version of the Coverity checker.
5849
Georg Brandl21e99f42010-03-07 15:23:59 +00005850- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005851 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5852 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005853
Georg Brandl3ee81df2008-05-17 18:14:43 +00005854- Issue #1686386: Tuple's tp_repr did not take into account the
5855 possibility of having a self-referential tuple, which is possible
5856 from C code. Nor did object's tp_str consider that a type's tp_str
5857 could do something that could lead to an inifinite recursion.
5858 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5859 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005861- Issue #1164: It was possible to trigger deadlock when using the
5862 'print' statement to write to a file since the GIL was not released
5863 as needed. Now PyObject_Print() does the right thing along with
5864 various tp_print implementations of the built-in types and those in
5865 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005866
Georg Brandl3ee81df2008-05-17 18:14:43 +00005867- Issue #1147: Exceptions were directly allowing string exceptions in
5868 their throw() method even though string exceptions no longer
5869 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005870

Brett Cannon1e534b52007-09-07 04:18:30 +00005874- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005875 PyObject_Call() never calling back out to Python code to trigger
5876 recursion depth updates/checks. Required the creation of a static
5877 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005895 __*__ attributes. (Some already existed, e.g., __doc__ and
5896 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005897

5906 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005907
Brett Cannon229cee22007-05-05 01:34:02 +00005908- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005914 setting a plain string, ie don't expand to single letter identifiers.
5915
Raymond Hettinger13936692007-04-11 18:40:58 +00005916- Request #1191699: Slices can now be pickled.

5926
Guido van Rossum143b5642007-03-23 04:58:42 +00005927- Bug #1683368: The object.__init__() and object.__new__() methods are
5928 now stricter in rejecting excess arguments. The only time when
5929 either allows excess arguments is when it is not overridden and the
5930 other one is. For backwards compatibility, when both are
5931 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005932 warning later). Also, type.__init__() insists on the same signature
5933 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005934
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5936 object to complex using its __complex__() method before falling back
5937 to the __float__() method. Therefore, the functions in the cmath
5938 module now can operate on objects that define a __complex__()
5939 method.

5956
Georg Brandl7b9c5552007-03-12 14:30:05 +00005957- Bug #1678647: write a newline after printing an exception in any
5958 case, even when converting the value to a string failed.
5959
Georg Brandl871f1bc2007-03-12 13:17:36 +00005960- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005961 its argument, if it exists. If not, it will work like before. This
5962 allows customizing the output of dir() in the presence of a
5963 __getattr__().

5973 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005974
Georg Brandlaa2321b2007-03-07 00:40:28 +00005975- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976 makes the filenames the warning module prints much more sensible
5977 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005978

Georg Brandl0fca97a2007-03-05 22:28:08 +00005990- Patch #1674228: when assigning a slice (old-style), check for the
5991 sq_ass_slice instead of the sq_slice slot.
5992
Georg Brandl3ee81df2008-05-17 18:14:43 +00005993- When printing an unraisable error, don't print exceptions. before

6621 accepted in TestSuite.addTest(). This should cause no
6622 incompatibility since it never made sense with ordinary subclasses
6623 -- the failure just occurred later, with a more cumbersome
6624 exception.

6908 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006909
Georg Brandl3ee81df2008-05-17 18:14:43 +00006910- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006911 that the SMTP.starttls() caller no longer needs to call ehlo()
6912 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913 does not claim to support starttls. Adds the
6914 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007013 time so that opening a database previously created with the DB_DUP
7014 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7015 opens. Specifically: dictionary assignment to a DB object will
7016 replace all values for a given key when the database allows
7017 duplicate values. DB users should use DB.put(k, v) when they want
7018 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007019

7025 characters with ASCII value less than 32. Also, it correctly quotes
7026 dots only if they occur on a single line, as opposed to the previous
7027 behavior of quoting dots if they are the second character of any
7028 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007345- Makefile.pre.in(buildbottest): Run an optional script
7346 pybuildbot.identify to include some information about the build
7347 environment.

Neal Norwitz92422fb2006-08-18 03:57:54 +00007350C API
7351-----
7352
Georg Brandl3ee81df2008-05-17 18:14:43 +00007353- Unified naming convention for free lists and their limits. All free
7354 lists in Object/ are named ``free_list``, the counter ``numfree``
7355 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7356 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007357
Georg Brandl3ee81df2008-05-17 18:14:43 +00007358- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7359 to ``PyTuple_SetItem``, it can be used to populate a brand new
7360 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007361
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007362- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007363
Georg Brandl3ee81df2008-05-17 18:14:43 +00007364- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7365 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7366 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007367
7368- Patch #1720595: add T_BOOL to the range of structmember types.
7369
7370- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7371 ``PyFloat_GetInfo()`` to the float API.
7372
Georg Brandl3ee81df2008-05-17 18:14:43 +00007373- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7374 of w# format code incorrectly truncated the length to an int, even
7375 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7376 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007377
Georg Brandl3ee81df2008-05-17 18:14:43 +00007378- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7379 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007380
Georg Brandl3ee81df2008-05-17 18:14:43 +00007381- PEP 3123: Provide forward compatibility with Python 3.0, while
7382 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7383 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007384
Georg Brandl3ee81df2008-05-17 18:14:43 +00007385- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7386 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007387
7388- Patch #1733960: Allow T_LONGLONG to accept ints.
7389
7390- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7391
Christian Heimes000a0742008-01-03 22:16:32 +00007392- Added a new API function ``PyImport_ImportModuleNoBlock``.
7393
Georg Brandl6caad7d2008-01-26 14:19:22 +00007394- Bug #1637022: Prefix AST symbols with _Py_.
7395
7396- Fix some leftovers from the conversion from int to Py_ssize_t
7397 (relevant to strings and sequences of more than 2**31 items).
7398
7399- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7400 outside of pystate.c and should not be necessary.
7401
Georg Brandl3ee81df2008-05-17 18:14:43 +00007402- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7403 absolute imports. In earlier versions they might have used relative
7404 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007405
Georg Brandl3ee81df2008-05-17 18:14:43 +00007406- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7407 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007408
Georg Brandl3ee81df2008-05-17 18:14:43 +00007409- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7410 macro so it can be used as an expression.

7415
Georg Brandl3ee81df2008-05-17 18:14:43 +00007416- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7417 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7418 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7419 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007420
Georg Brandl3ee81df2008-05-17 18:14:43 +00007421- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7422 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007434- Removed the macfs module. It had been deprecated since Python 2.5.
7435 This lead to the deprecation of macostools.touched() as it relied
7436 solely on macfs and was a no-op under OS X.
