Ned Deily18fae3f2013-01-31 01:24:55 -0800696- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
697 In particular, fix extension module build failures when trying to use
698 32-bit-only installer Pythons on systems with Xcode 4 (currently
699 OS X 10.8, 10.7, and optionally 10.6).
700 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
701 * Since Xcode 4 removes ppc support, extension module builds now
702 check for ppc compiler support and by default remove ppc and
703 ppc64 archs when they are not available.
704 * Extension module builds now revert to using system installed
705 headers and libs (/usr and /System/Library) if the SDK used
706 to build the interpreter is not installed or has moved.
707 * Try to avoid building extension modules with deprecated
708 and problematic Apple llvm-gcc compiler. If original compiler
709 is not available, use clang instead by default.

905
Antoine Pitrou5b4b2da2011-12-15 14:15:31 +0100906- Fix the fix for issue #12149: it was incorrect, although it had the side
907 effect of appearing to resolve the issue. Thanks to Mark Shannon for
908 noticing.
909
Amaury Forgeot d'Arc4bf21e22011-12-07 21:46:48 +0100910- Issue #13546: Fixed an overflow issue that could crash the intepreter when

Mark Hammond323b5da2011-10-17 11:05:36 +1100927- Issue #7833: Extension modules built using distutils on Windows will no
928 longer include a "manifest" to prevent them failing at import time in some
929 embedded situations.
930
Benjamin Petersona7b09762011-10-15 13:43:21 -0400931- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +0100940- Issue #12973: Fix overflow checks that invoked undefined behaviour in
941 int.__pow__. These overflow checks were causing int.__pow__ to produce
942 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100943 compiler optimizing the check away. Also fix similar overflow checks
944 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
945 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +0100946

Antoine Pitrou16166452011-07-12 22:04:20 +0200956- Issue #12149: Update the method cache after a type's dictionnary gets
957 cleared by the garbage collector. This fixes a segfault when an instance
958 and its type get caught in a reference cycle, and the instance's
959 deallocator calls one of the methods on the type (e.g. when subclassing
960 IOBase). Diagnosis and patch by Davide Rizzo.
961
Florent Xiclunaa1f948b2012-01-24 21:05:10 +0100962- Issue #12501: Remove Py3k warning for callable. callable() is supported
963 again in Python 3.2.

967
Victor Stinnerd3c7e172011-05-30 23:49:13 +0200968- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +0200969 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
970 raw_input() interrupted by CTRL+c.
971
Łukasz Langa7a153902011-10-18 17:16:00 +0200972- Issue #10860: httplib now correctly handles an empty port after port
973 delimiter in URLs.
974
Barry Warsawc5643282011-07-19 17:06:30 -0400975- dict_proxy objects now display their contents rather than just the class
976 name.

Florent Xiclunac2279652012-02-12 14:49:03 +01001013- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001014 has left two versions of customize_compiler, the original in
1015 distutils.sysconfig and another copy in distutils.ccompiler, with some
1016 parts of distutils calling one and others using the other.
1017 Complete the revert back to only having one in distutils.sysconfig as
1018 is the case in 3.x.
1019
Ned Deily0d0ea482012-02-10 12:59:06 +01001020- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1021 Distutils-based packages with C extension modules may fail because
1022 Apple has removed gcc-4.2, the version used to build python.org
1023 64-bit/32-bit Pythons. If the user does not explicitly override
1024 the default C compiler by setting the CC environment variable,
1025 Distutils will now attempt to compile extension modules with clang
1026 if gcc-4.2 is required but not found. Also as a convenience, if
1027 the user does explicitly set CC, substitute its value as the default
1028 compiler in the Distutils LDSHARED configuration variable for OS X.
1029 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1030 SDK, neither of which are available in Xcode 4. This change does not
1031 attempt to override settings to support their use with Xcode 4.)
1032

Senthil Kumaran607e31e2012-02-09 17:43:31 +08001035- Issue #6005: Examples in the socket library documentation use sendall, where
1036 relevant, instead send method.
1037
Petri Lehtinenc7fd5232011-05-09 12:24:09 +02001038- Issue #10811: Fix recursive usage of cursors. Instead of crashing,

1040

Ned Deilyd8fdbad2011-12-14 15:05:42 -08001094- Issue #4625: If IDLE cannot write to its recent file or breakpoint

1116 raised when the wrapped raw file is non-blocking and the write would block.

Éric Araujob21f51a2011-10-23 04:37:51 +02001165 does, instead of converting it to a raw buffer. This also fixes handling of

Ned Deily87e82bb2011-06-28 19:52:59 -07001304- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1305 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1306 interpreter process. This could cause failures in non-Distutils subprocesses
1307 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001308 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001309 deployment target only in the environment of each build subprocess. It is
1310 still possible to globally override the default by setting
1311 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1312 greater or equal to the default value, the value with which the interpreter
1313 was built.

1342 updating the check interval, so if the user decreases the check interval,
1343 the ticker doesn't have to wind down to zero from the old starting point
1344 before the new interval takes effect. And if the user increases the
1345 interval, it makes sure the new limit takes effect right away rather have an
1346 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002761- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2762 start byte and the continuation byte(s) are now considered invalid, instead
2763 of the number of bytes specified by the start byte.
2764 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2765 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2766 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002775- Issue #8748: Fix two issues with comparisons between complex and integer
2776 objects. (1) The comparison could incorrectly return True in some cases
2777 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2778 (2) The comparison raised an OverflowError for large integers, leading
2779 to unpredictable exceptions when combining integers and complex objects
2780 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002782- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003121- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003122 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3123 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3124 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3144Core and Builtins
3145-----------------
3146
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003147- Issue #7301: Add environment variable $PYTHONWARNINGS.
3148
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003149- Issue #8329: Don't return the same lists from select.select when no fds are
3150 changed.
3151
Georg Brandlfee0f442010-05-22 21:26:21 +00003152- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003153 on 64-bit machines. The shift count for either left or right shift is
3154 permitted to be up to sys.maxsize.
3155
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003156- Ensure that tokenization of identifiers is not affected by locale.
3157
Georg Brandlfee0f442010-05-22 21:26:21 +00003158- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003159
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003160- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3161
Georg Brandlfee0f442010-05-22 21:26:21 +00003162- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3163 with a non-empty format string. This is an effort to future-proof user
3164 code. If a derived class does not currently implement __format__ but later
3165 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003166 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003167 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003168
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003169- Issue #8268: Old-style classes (not just instances) now support weak
3170 references.
3171
Georg Brandlfee0f442010-05-22 21:26:21 +00003172- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3173 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003174
Victor Stinnerc7790ed2010-03-22 12:36:28 +00003175- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00003177- Issue #6474: Make error message from passing an inadequate number of keyword
3178 arguments to a function correct.
3179
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003180- Issue #8164: Don't allow lambda functions to have a docstring.
3181
Victor Stinner66644262010-03-10 22:30:19 +00003182- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003183 (SIGINT). If an error occurs while importing the site module, the error is
3184 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003185 module.
3186
Collin Winter001a3952010-03-18 21:54:01 +00003187- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00003192- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
3193
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003194- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003195 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3196 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003198- Issue #8310: Allow dis to examine new style classes.
3199
Georg Brandlfee0f442010-05-22 21:26:21 +00003200- Issue #8257: The Decimal construct now accepts a float instance directly,
3201 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003202
3203 >>> Decimal(1.1)
3204 Decimal('1.100000000000000088817841970012523233890533447265625')
3205
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003206- collections.Counter() now supports a subtract() method.
3207
Georg Brandlfee0f442010-05-22 21:26:21 +00003208- The functools module now has a total_ordering() class decorator to simplify
3209 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003210
Georg Brandlfee0f442010-05-22 21:26:21 +00003211- The functools module also adds cmp_to_key() as a tool to transition old-style
3212 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003213
Georg Brandlfee0f442010-05-22 21:26:21 +00003214- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3215 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003216
Georg Brandlfee0f442010-05-22 21:26:21 +00003217- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3218 InvalidOperation instead of returning False. (Comparisons involving a quiet
3219 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3220 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003221
Georg Brandlfee0f442010-05-22 21:26:21 +00003222- Issue #2531: Comparison operations between floats and Decimal instances now
3223 return a result based on the numeric values of the operands; previously they
3224 returned an arbitrary result based on the relative ordering of id(float) and
3225 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003226
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003227- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003228 argument `-` which tells it to read files to compile from stdin. Each line is
3229 read on demand and the named file is compiled immediately. (Original patch by
3230 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003231
Georg Brandlfee0f442010-05-22 21:26:21 +00003232- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3233 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003235- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3236 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003237 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003238
Georg Brandlfee0f442010-05-22 21:26:21 +00003239- Comparisons using one of <, <=, >, >= between a complex instance and a
3240 Fractions instance now raise TypeError instead of returning True/False. This
3241 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3242 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003243
Michael Foorde6410c52010-03-29 20:04:23 +00003244- Addition of ``WeakSet`` to the ``weakref`` module.

3252
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003253- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003254 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3255 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003256
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003257- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3258 deprecated.
3259
Georg Brandlfee0f442010-05-22 21:26:21 +00003260- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3261 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003262

3267 existing at the same time, causing a Unicode error when configuration code
3268 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003269
Georg Brandlfee0f442010-05-22 21:26:21 +00003270- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
3271 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00003272
Antoine Pitroueee91cd2010-03-26 19:27:16 +00003273- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3274 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3275 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003297- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003298 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3299 log file to compute the next rollover time. If the log file does not exist,
3300 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003301

Georg Brandlba83f822010-03-14 09:50:54 +00003310- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3311 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3312 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003341- Issue #8300: When passing a non-integer argument to struct.pack with any
3342 integer format code, struct.pack first attempts to convert the non-integer
3343 using its __index__ method. If that method is non-existent or raises
3344 TypeError it goes on to try the __int__ method, as described below.
3345
Georg Brandlba83f822010-03-14 09:50:54 +00003346- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3347 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3348 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003349 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3350 inconsistent: __int__ was used for some integer codes but not for others, and
3351 the set of integer codes for which it was used differed between native packing
3352 and standard packing.)

3756Core and Builtins
3757-----------------
3758
Georg Brandlba83f822010-03-14 09:50:54 +00003759- The ``__complex__()`` method is now looked up on the class of instances to
3760 make it consistent with other special methods.

3764
Mark Dickinson1b34d252010-01-01 17:27:30 +00003765- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003766 DeprecationWarning when passed a float argument where an integer was expected.
3767 These functions and methods now raise TypeError instead. The majority of the
3768 effects of this change are in the extension modules, but some core functions
3769 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3770 and many unicode/str methods.

3781 used to drop the time part of the result.
3782
Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #1811: Improve accuracy and cross-platform consistency for true division
3784 of integers: the result of a/b is now correctly rounded for ints a and b (at
3785 least on IEEE 754 platforms), and in particular does not depend on the
3786 internal representation of a long.

3794
Georg Brandlba83f822010-03-14 09:50:54 +00003795 These executables now work properly with the arch(1) command: ``arch -ppc
3796 python`` will start a universal binary version of python in PPC mode (unlike

3937 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003938
Georg Brandlba83f822010-03-14 09:50:54 +00003939- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3940 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003941
Georg Brandlba83f822010-03-14 09:50:54 +00003942- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3943 1e-100 used to raise OverflowError, but now gives the requested 120
3944 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003952
Georg Brandlba83f822010-03-14 09:50:54 +00003953- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3954 decimal string that's guaranteed to round back to x under correct rounding
3955 (with round-half-to-even rounding mode). Previously it gave a string based on
3956 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3957 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3958 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003959
Georg Brandlba83f822010-03-14 09:50:54 +00003960- Issue #7117: On almost all platforms: float-to-string and string-to-float
3961 conversions within Python are now correctly rounded. Places these conversions
3962 occur include: str for floats and complex numbers; the float and complex
3963 constructors; old-style and new-style numeric formatting; serialization and
3964 deserialization of floats and complex numbers using marshal, pickle and json;
3965 parsing of float and imaginary literals in Python code; Decimal-to-float
3966 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003967
Georg Brandlba83f822010-03-14 09:50:54 +00003968 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3969 providing correctly-rounded strtod and dtoa C functions. This code is
3970 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3971 the C compiler. There may be a small number of platforms on which correct
3972 operation of this code cannot be guaranteed, so the code is not used: notably,
3973 this applies to platforms where the C double format is not IEEE 754 binary64,
3974 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3975 and Python's configure script is unable to determine how to change the FPU
3976 precision. On these platforms conversions use the platform strtod and dtoa,
3977 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003978
Georg Brandlba83f822010-03-14 09:50:54 +00003979- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3980 uses the correctly-rounded string <-> float conversions described above (when
3981 available), and so produces correctly rounded results that will display nicely
3982 under the float repr. There are two related small changes: (1) round now
3983 accepts any class with an ``__index__()`` method for its second argument (but
3984 no longer accepts floats for the second argument), and (2) an excessively
3985 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3986 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003990- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004128
Georg Brandlba83f822010-03-14 09:50:54 +00004129 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4130 (2) parsing of strings representing infinities and nans was locale aware; and
4131 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004133- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4134 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4135 but with at least one decimal point and with a default precision
4136 of 12. Previously, the behavior the same but with a default precision of 6.
4137 This more closely matches ``str()``, and reduces surprises when adding
4138 alignment flags to the empty presentation type. This also affects the new
4139 complex.__format__ in the same way.
4140
4141- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4142 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00004204 untrackable objects are not tracked by the garbage collector. This can reduce

4213 internal representation of integers, for performance reasons. Base 2**30 is
4214 enabled by default on 64-bit machines. Add --enable-big-digits option to

4336
Georg Brandlba83f822010-03-14 09:50:54 +00004337- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4338 file objects with closefd=False. The file descriptor is still kept open but
4339 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004363- On windows, ``os.chdir()`` given unicode was not working if
4364 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4365 this code path is really executed because I cannot move to such directory on
4366 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004368- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4369 element is temporarily replaced with an equivalent frozenset. But the
4370 eventual KeyError would always report the empty ``frozenset()`` as the missing
4371 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004391- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4392 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4393 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4394 of using the replace error handler in PyUnicode_DecodeUTF8().
4395
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004396- Issue #3739: The unicode-internal encoder now reports the number of characters

4398
Georg Brandlba83f822010-03-14 09:50:54 +00004399- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4401 gives improved memory leak detection when running under Valgrind, while taking
4402 advantage of pymalloc at other times.

5654 test_warnings have been adjusted to use it, tests for other modules with both
5655 C and Python implementations in the stdlib can be adjusted to use it over
5656 time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005769- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5770 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5771 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5772 ``printf`` function, whereas PyString_FromFormat has an independent
5773 implementation and uses "%zd" on all platforms for size_t values.
5774 This makes a difference on win64, where ``printf`` needs "%Id" to display
5775 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005792 was correctly parsed but parsing of subsequent arguments failed.
5793
Vinay Sajip35e3b032008-09-01 14:33:59 +00005794- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005795 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5796 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5797 when given a tuple of classes as second argument, were looking up
5798 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5799 type object.

5949 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5950 to their tp_flags field if they care. This is a backwards
5951 compatibility feature; in 3.0, all types will use the cache by
5952 default.
5953
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005954- Keyword arguments can now follow starred arguments. (``f(a, *args,
5955 keyword=23)`` is now valid syntax.)
5956
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005957- ctypes function pointers that are COM methods have a boolean True
5958 value again.
5959
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005960- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5961 by denying s# to parse objects that have a releasebuffer procedure,
5962 and introducing s*.
5963
Georg Brandl1e13ea92008-08-11 09:07:59 +00005964- Issue #3537: Fix an assertion failure when an empty but presized dict
5965 object was stored in the freelist.
5966
Mark Dickinsonb6467572008-08-04 21:30:09 +00005967- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5968 ValueError consistently across platforms.
5969
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005970- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5971 (64bit Unix, for example), unichr() would truncate its argument and return
5972 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5973
Neal Norwitze7d8be82008-07-31 17:17:14 +00005974- Apply security patches from Apple.
5975
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005976- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5977 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5978
Antoine Pitrou92f82162008-07-25 22:22:08 +00005979- Issue #1819: function calls with several named parameters are now on
5980 average 35% faster (as measured by pybench).
5981
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005982- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5983 the python debugger steps into a class statement: the free variables (local
5984 variables defined in an outer scope) would be deleted from the outer scope.
5985
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005986- Issue #2620: Overflow checking when allocating or reallocating memory
5987 was not always being done properly in some python types and extension
5988 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5989 all been updated to perform better checks and places in the code that
5990 would previously leak memory on the error path when such an allocation
5991 failed have been fixed.

5997
Benjamin Petersone977ad42008-08-20 01:42:01 +00005998- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5999 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6000
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006001- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6002 version reported by these tools does not necessarily follow the python
6003 version numbering scheme, so the module is less strict when parsing it.
6004
Nick Coghlanf70385a2008-08-18 12:42:46 +00006005- Issue #2235: Added Py3k warnings for types which will become unhashable
6006 under the stricter __hash__ inheritance rules in 3.0. Several types
6007 which did not meet the rules for hash invariants and were already
6008 unhashable in 3.0 have now been explicitly flagged as unhashable in
6009 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6010 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6011
Brett Cannon88f801d2008-08-18 00:46:22 +00006012- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6013 imported into the module but exposed as part of the module's API.
6014

6020
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006021- Issue #3575: Incremental decoder's decode function now takes bytearray
6022 by using 's*' instead of 't#'.
6023
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006024- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006025 fails unicode conversion on 2nd parameter. (windows only)

Facundo Batistaeb90b782008-08-16 14:44:07 +00006033- Issue #2776: fixed small issue when handling an URL with double slash
6034 after a 302 response in the case of not going through a proxy.
6035
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006036- Issue #2676: in the email package, content-type parsing was hanging on
6037 pathological input because of quadratic or exponential behaviour of a
6038 regular expression.
6039
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006040- Issue #3476: binary buffered reading through the new "io" library is now
6041 thread-safe.
6042
Brett Cannonbf3157b2008-08-14 05:00:03 +00006043- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6044 since mimetools itself is deprecated. Because modules are cached, all
6045 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6046
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006047- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00006049- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6050 menu entries were not deleted.
6051
Brett Cannon83e81842008-08-09 23:30:55 +00006052- Copied the implementation of reduce() to _functools.reduce() to have a
6053 version that did not raise a DeprecationWarning under -3.
6054
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006055- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6056 a MemoryError rather than silently stop the iteration.
6057
Guido van Rossum59ce9012008-08-09 14:55:34 +00006058- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6059 to _sre.compile() will now be rejected. This should not affect anybody
6060 since the re.compile() function never generates invalid re-bytecode.
6061
Skip Montanaroa032bf42008-08-08 22:52:51 +00006062- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6063 upon first access it can be automatically initialized from the csv file if
6064 it wasn't initialized during instantiation.
6065
Brett Cannon3aa2a492008-08-06 22:28:09 +00006066- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6067 the reload() built-in has been removed.
6068
Brett Cannon7e30b672008-08-04 21:52:25 +00006069- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006070 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6078 raised an AttributeError.
6079
Benjamin Peterson01a24322008-07-28 23:35:27 +00006080- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006081 asking for a specific length. This problem only affected files opened
6082 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006083

6106
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006107- Issue #3394: zipfile.writestr sets external attributes when passed a
6108 file name rather than a ZipInfo instance, so files are extracted with
6109 mode 0600 rather than 000 under Unix.
6110
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006111- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6112 argument in python 2.5, this broke code that subclassed Popen to include its
6113 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006123- Issue #2235: the C API function PyObject_HashNotImplemented and its
6124 interaction with the tp_hash slot (added in 2.6b2) are now documented
6125
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006126- Issue #643841: The language reference now provides more detailed
6127 coverage of the lookup process for special methods. The disclaimers
6128 regarding lack of coverage of new-style classes have also been
6129 removed, since the coverage is now fairly reasonable.

6133================================
6134
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006135*Release date: 17-Jul-2008*
6136
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006137Core and Builtins
6138-----------------
6139
Georg Brandl3e483f62008-07-16 22:57:41 +00006140- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6141 its methods now allow for items objects that can be converted to
6142 an integer using operator.index().
6143
Mark Dickinson64b7e502008-07-16 09:40:03 +00006144- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6145 produced a ValueError instead of giving the correct float.
6146
Eric Smitha5fa5a22008-07-16 00:11:49 +00006147- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6148 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6149
Mark Dickinson7103aa42008-07-15 19:08:33 +00006150- Issue #3008: the float type has a new instance method 'float.hex'
6151 and a new class method 'float.fromhex' to convert floating-point
6152 numbers to and from hexadecimal strings, respectively.
6153
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006154- Issue #2235: __hash__ is once again inherited by default. To allow
6155 collections.Hashable to remain meaningful in the presence of the
6156 default hash implementation (object.__hash__), it is now possible
6157 to explicit block inheritance of hash by setting __hash__=None at
6158 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6159 level.
6160
Nick Coghlanb028f502008-07-13 14:52:36 +00006161- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6162 the parent module cannot be found while performing an absolute import.
6163 This means that an incorrectly defined __package__ attribute will
6164 now only prevent relative imports in that module rather than causing
6165 all imports from that module to fail.
6166
Nick Coghlan14ff9942008-07-08 14:21:42 +00006167- Issue #2517: Allow unicode messages in Exceptions again by correctly
6168 bypassing the instance dictionary when looking up __unicode__ on
6169 new-style classes.
6170
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006171- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6172 set to a custom object whose write() method happens to install
6173 another file in sys.stdout.
6174
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006175- Issue #3088: Corrected a race condition in classes derived from
6176 threading.local: the first member set by a thread could be saved in
6177 another thread's dictionary.
6178
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006179- Issue #3004: Minor change to slice.indices(): the start and stop
6180 arguments are now treated identically, making the behaviour easier
6181 to describe and understand. For example, slice(None, -10,
6182 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6183 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6184 10, -1).
6185
Georg Brandl278fc502008-07-19 12:46:12 +00006186- Issue #3219: Calling a function with repeated keyword arguments,
6187 f(a=2, a=23), would not cause a syntax error. This was a regression
6188 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006189
Georg Brandl278fc502008-07-19 12:46:12 +00006190- Issue #2862: Make int and float freelist management consistent with
6191 other freelists. Changes their CompactFreeList apis into
6192 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006193

Thomas Heller57adf222008-08-14 19:10:48 +00006197- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6198 api functions without holding the GIL, which could lead to a fatal
6199 error when they failed.
6200
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006201- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6210 ForkingPickler.register() to resolve conflict with ctypes.
6211
Vinay Sajip51e65192008-07-18 09:01:10 +00006212- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006214- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6215 a valid dlerror() message.
6216
Thomas Heller2bad6572008-07-15 17:19:50 +00006217- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6218 incomplete structure was created.
6219
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006220- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00006222- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6223
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006224- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006225
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006226- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6227 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006228 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006229 content-length. The problem had been corrected in the 2.4 branch, but never
6230 merged into trunk.
6231
Georg Brandle78fbcc2008-07-05 10:13:36 +00006232- Issue #2663: add filtering capability to shutil.copytree().

6637 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006638 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006639
6640 This is controlled by the configure argument ``--with-universal-archs``:
6641
6642 - ``--with-universal-archs=all``: install 4-way universal
6643
6644 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6645
6646 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6647
6648 This option should be used in combination with ``--enable-universalsdk=``.
6649
6650 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 +00006700- Issue #1631171: Re-implement the 'warnings' module in C (the
6701 original Python code has been kept as backup). This will allow for
6702 using the 'warning's machinery in such places as the parser where
6703 use of pure Python code is not possible. Both the ``showarning()``
6704 and ``formatwarning()`` gain an optional 'line' argument which is
6705 not called by default for backwards-compatibility reasons. Setting
6706 ``warnings.showwarning()`` to an implementation that lacks support
6707 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006770- Issue #2550: The approach used by client/server code for obtaining
6771 ports to listen on in network-oriented tests has been refined in an
6772 effort to facilitate running multiple instances of the entire
6773 regression test suite in parallel without issue.
6774 test_support.bind_port() has been fixed such that it will always
6775 return a unique port -- which wasn't always the case with the
6776 previous implementation, especially if socket options had been set
6777 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6778 new implementation of bind_port() will actually raise an exception
6779 if it is passed an AF_INET/SOCK_STREAM socket with either the
6780 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6781 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6782 the socket it's been passed. This currently only applies to
6783 Windows. This option prevents any other sockets from binding to the
6784 host/port we've bound to, thus removing the possibility of the
6785 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6786 when a second SOCK_STREAM socket binds and accepts to a host/port
6787 that's already been bound by another socket. The optional preferred
6788 port parameter to bind_port() has been removed. Under no
6789 circumstances should tests be hard coding ports!
6790
6791 test_support.find_unused_port() has also been introduced, which will
6792 pass a temporary socket object to bind_port() in order to obtain an
6793 unused port. The temporary socket object is then closed and
6794 deleted, and the port is returned. This method should only be used
6795 for obtaining an unused port in order to pass to an external program
6796 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6797 a parameter to a server-oriented class that doesn't give you direct
6798 access to the underlying socket used.
6799
6800 Finally, test_support.HOST has been introduced, which should be used
6801 for the host argument of any relevant socket calls (i.e. bind and
6802 connect).

6807 test_asynchat and test_socket_ssl.
6808

7077-----------------
7078
Fred Drakea8ee94b2008-03-01 02:45:07 +00007079- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007080 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007081
Georg Brandlad61bc82008-02-23 15:11:18 +00007082- Issue #2067: file.__exit__() now calls subclasses' close() method.
7083
7084- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007085
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007086- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007087 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007088
Eric Smitha73fbe72008-02-23 03:09:44 +00007089- Added the future_builtins module, which contains hex() and oct().
7090 These are the PEP 3127 version of these functions, designed to be
7091 compatible with the hex() and oct() builtins from Python 3.0. They
7092 differ slightly in their output formats from the existing, unchanged
7093 Python 2.6 builtins. The expected usage of the future_builtins
7094 module is:
7095 from future_builtins import hex, oct
7096
Eric Smith7ef40bf2008-02-20 23:34:22 +00007097- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7098 exponents for exponents with absolute value < 100. Follows C99
7099 standard. This is a change on Windows, which would use 3 digits.
7100 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7101 so that any alterations it does to the resulting string will be
7102 available in stringlib/formatter.h (for float.__format__).
7103
Eric Smith5a3c1352008-02-19 13:21:56 +00007104- Implemented PEP 3101, Advanced String Formatting. This adds a new
7105 builtin format(); a format() method for str and unicode; a
7106 __format__() method to object, str, unicode, int, long, float, and
7107 datetime; the class string.Formatter; and the C API
7108 PyObject_Format().
7109
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110- Fixed several potential crashes, all caused by specially crafted
7111 __del__ methods exploiting objects in temporarily inconsistent
7112 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007113
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007114- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007115 prevent a possible crash: an Abstract Base Class would try to access
7116 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007117
Georg Brandl3ee81df2008-05-17 18:14:43 +00007118- Fixed repr() and str() of complex numbers with infinity or nan as
7119 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007120
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Clear all free lists during a gc.collect() of the highest generation
7122 in order to allow pymalloc to free more arenas. Python may give back
7123 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007124
Georg Brandl3ee81df2008-05-17 18:14:43 +00007125- Issue #2045: Fix an infinite recursion triggered when printing a
7126 subclass of collections.defaultdict, if its default_factory is set
7127 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007128
Christian Heimesf75dbef2008-02-08 00:11:31 +00007129- Fixed a minor memory leak in dictobject.c. The content of the free
7130 list was not freed on interpreter shutdown.
7131
Georg Brandl21e99f42010-03-07 15:23:59 +00007132- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007134
Georg Brandl3ee81df2008-05-17 18:14:43 +00007135- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7136 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007137 to compact the internal free lists of pre-allocted ints and floats.
7138
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7140 calls. Python expected the return type int but the fork familie
7141 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007142
Georg Brandl3ee81df2008-05-17 18:14:43 +00007143- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7144 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007145
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7147 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007148
Georg Brandl3ee81df2008-05-17 18:14:43 +00007149- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7150 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007151
Georg Brandl3ee81df2008-05-17 18:14:43 +00007152- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7153 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007154
Georg Brandl3ee81df2008-05-17 18:14:43 +00007155- Patch #1473257: generator objects gain a gi_code attribute. This is
7156 the same object as the func_code attribute of the function that
7157 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007158
Georg Brandl3ee81df2008-05-17 18:14:43 +00007159- Issue #1920: "while 0" statements were completely removed by the
7160 compiler, even in the presence of an "else" clause, which is
7161 supposed to be run when the condition is false. Now the compiler
7162 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007163
Guido van Rossumeead05f2008-01-24 18:21:02 +00007164- A few crashers fixed: weakref_in_del.py (issue #1377858);
7165 loosing_dict_ref.py (issue #1303614, test67.py);
7166 borrowed_ref_[34].py (not in tracker).
7167
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007168- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007169 suppressed while an extension is loaded by calling SetErrorMode in
7170 dynload_win.c. The error is still reported properly.
7171
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007173 several extension methods and modules do not work without unicode
7174 support.
7175
Georg Brandl26543b12008-01-21 18:36:51 +00007176- Issue #1882: when compiling code from a string, encoding cookies in the
7177 second line of code were not always recognized correctly.
7178
Georg Brandl14404b62008-01-19 19:27:05 +00007179- Issue #1679: "0x" was taken as a valid integer literal.
7180
Georg Brandl6caad7d2008-01-26 14:19:22 +00007181- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007182 added.
7183
Christian Heimesc94e2b52008-01-14 04:13:37 +00007184- sys.float_info / PyFloat_GetInfo: The floating point information
7185 object was converted from a dict to a specialized structseq object.
7186
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187- Patch #1816: Added sys.flags structseq. It exposes the status of
7188 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007189
Georg Brandl3ee81df2008-05-17 18:14:43 +00007190- Objects/structseq.c: Implemented new structseq representation. The
7191 patch makes structseqs (e.g. the return value of os.stat) more
7192 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007193
Georg Brandl3ee81df2008-05-17 18:14:43 +00007194- Patch #1700288: added a type attribute cache that caches method
7195 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007196
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007197- Bug #1776: __import__() no longer accepts filenames on any platform.
7198 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007199
Georg Brandlaed6c662008-01-07 17:25:53 +00007200- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7201
Georg Brandl3ee81df2008-05-17 18:14:43 +00007202- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7203 envvar and sys.dont_write_bytecode attribute. All these can be set
7204 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007205
Georg Brandl3ee81df2008-05-17 18:14:43 +00007206- Improve some exception messages when Windows fails to load an
7207 extension module. Now we get for example '%1 is not a valid Win32
7208 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007212- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7213 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007214
Christian Heimes0a8143f2007-12-18 23:22:54 +00007215- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007216 and INF. float("nan"), float("inf") and float("-inf") now work on
7217 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007218
Georg Brandl3ee81df2008-05-17 18:14:43 +00007219- Compiler now generates simpler and faster code for dictionary
7220 literals. The oparg for BUILD_MAP now indicates an estimated
7221 dictionary size. There is a new opcode, STORE_MAP, for adding
7222 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007223
Georg Brandl3ee81df2008-05-17 18:14:43 +00007224- Issue #1638: %zd configure test fails on Linux.

7230 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007231
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007232- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007233 SystemError.
7234
Nick Coghlanef01d822007-12-03 12:55:17 +00007235- PEP 366: Allow explicit relative imports when executing modules
7236 inside packages with the -m switch via a new module level
7237 __package__ attribute.
7238
Georg Brandl3ee81df2008-05-17 18:14:43 +00007239- Issue #1402: Fix a crash on exit, when another thread is still
7240 running, and if the deallocation of its frames somehow calls the
7241 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007242

7252 file can now be directly executed by passing their name to the
7253 interpreter. The directory/zipfile is automatically inserted as the
7254 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007255
Georg Brandl3ee81df2008-05-17 18:14:43 +00007256- Issue #1265: Fix a problem with sys.settrace, if the tracing
7257 function uses a generator expression when at the same time the
7258 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007259
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007260- sets and frozensets now have an isdisjoint() method.
7261
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007262- optimize the performance of builtin.sum().
7263
Neal Norwitz44f326e2007-10-05 05:29:17 +00007264- Fix warnings found by the new version of the Coverity checker.
7265
Georg Brandl21e99f42010-03-07 15:23:59 +00007266- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007267 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7268 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007269
Georg Brandl3ee81df2008-05-17 18:14:43 +00007270- Issue #1686386: Tuple's tp_repr did not take into account the
7271 possibility of having a self-referential tuple, which is possible
7272 from C code. Nor did object's tp_str consider that a type's tp_str
7273 could do something that could lead to an inifinite recursion.
7274 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7275 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007276
Georg Brandl3ee81df2008-05-17 18:14:43 +00007277- Issue #1164: It was possible to trigger deadlock when using the
7278 'print' statement to write to a file since the GIL was not released
7279 as needed. Now PyObject_Print() does the right thing along with
7280 various tp_print implementations of the built-in types and those in
7281 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007282
Georg Brandl3ee81df2008-05-17 18:14:43 +00007283- Issue #1147: Exceptions were directly allowing string exceptions in
7284 their throw() method even though string exceptions no longer
7285 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00007290- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007291 PyObject_Call() never calling back out to Python code to trigger
7292 recursion depth updates/checks. Required the creation of a static
7293 RuntimeError instance in case normalizing an exception put the
7294 recursion check value past its limit. Fixes crashers
7295 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007310- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007311 __*__ attributes. (Some already existed, e.g., __doc__ and
7312 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007313
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007314- Add -3 option to the interpreter to warn about features that are

7318 calls.
7319
Collin Winter62903052007-05-18 23:11:24 +00007320- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007321 "except E as target:". This is to provide forwards compatibility
7322 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007323
Brett Cannon229cee22007-05-05 01:34:02 +00007324- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007329- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007330 setting a plain string, ie don't expand to single letter identifiers.
7331
Raymond Hettinger13936692007-04-11 18:40:58 +00007332- Request #1191699: Slices can now be pickled.
7333
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007334- Request #1193128: str.translate() now allows a None argument for

7336 remaining characters.
7337
Georg Brandl5cb76c12007-03-21 09:00:39 +00007338- Patch #1682205: a TypeError while unpacking an iterable is no longer

7342
Guido van Rossum143b5642007-03-23 04:58:42 +00007343- Bug #1683368: The object.__init__() and object.__new__() methods are
7344 now stricter in rejecting excess arguments. The only time when
7345 either allows excess arguments is when it is not overridden and the
7346 other one is. For backwards compatibility, when both are
7347 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007348 warning later). Also, type.__init__() insists on the same signature
7349 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007350
Georg Brandl3ee81df2008-05-17 18:14:43 +00007351- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7352 object to complex using its __complex__() method before falling back
7353 to the __float__() method. Therefore, the functions in the cmath
7354 module now can operate on objects that define a __complex__()
7355 method.

7372
Georg Brandl7b9c5552007-03-12 14:30:05 +00007373- Bug #1678647: write a newline after printing an exception in any
7374 case, even when converting the value to a string failed.
7375
Georg Brandl871f1bc2007-03-12 13:17:36 +00007376- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007377 its argument, if it exists. If not, it will work like before. This
7378 allows customizing the output of dir() in the presence of a
7379 __getattr__().

7388 parthensized forms. This means complex(repr(x)) now works instead of
7389 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007390
Georg Brandlaa2321b2007-03-07 00:40:28 +00007391- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007392 makes the filenames the warning module prints much more sensible
7393 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007406- Patch #1674228: when assigning a slice (old-style), check for the
7407 sq_ass_slice instead of the sq_slice slot.
7408
Georg Brandl3ee81df2008-05-17 18:14:43 +00007409- When printing an unraisable error, don't print exceptions. before

8020 Python would crash instead of raising an error.
8021

8034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- unittest now verifies more of its assumptions. In particular,
8036 TestCase and TestSuite subclasses (not instances) are no longer
8037 accepted in TestSuite.addTest(). This should cause no
8038 incompatibility since it never made sense with ordinary subclasses
8039 -- the failure just occurred later, with a more cumbersome
8040 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008321- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8322 with RFC 3207 and forgets any knowledge obtained from the server not
8323 obtained from the TLS negotiation itself. Patch contributed by Bill
8324 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008325
Georg Brandl3ee81df2008-05-17 18:14:43 +00008326- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008327 that the SMTP.starttls() caller no longer needs to call ehlo()
8328 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329 does not claim to support starttls. Adds the
8330 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8411 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8412 silently miscode subclasses of those types. Now, it raises a
8413 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008414

Georg Brandl3ee81df2008-05-17 18:14:43 +00008429 time so that opening a database previously created with the DB_DUP
8430 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8431 opens. Specifically: dictionary assignment to a DB object will
8432 replace all values for a given key when the database allows
8433 duplicate values. DB users should use DB.put(k, v) when they want
8434 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008435

8441 characters with ASCII value less than 32. Also, it correctly quotes
8442 dots only if they occur on a single line, as opposed to the previous
8443 behavior of quoting dots if they are the second character of any
8444 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008445

8767-----
8768
Georg Brandl3ee81df2008-05-17 18:14:43 +00008769- Unified naming convention for free lists and their limits. All free
8770 lists in Object/ are named ``free_list``, the counter ``numfree``
8771 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8772 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008773
Georg Brandl3ee81df2008-05-17 18:14:43 +00008774- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8775 to ``PyTuple_SetItem``, it can be used to populate a brand new
8776 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008777
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008778- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008780- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8781 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8782 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008783
8784- Patch #1720595: add T_BOOL to the range of structmember types.
8785
8786- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8787 ``PyFloat_GetInfo()`` to the float API.
8788
Georg Brandl3ee81df2008-05-17 18:14:43 +00008789- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8790 of w# format code incorrectly truncated the length to an int, even
8791 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8792 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008793
Georg Brandl3ee81df2008-05-17 18:14:43 +00008794- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8795 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008797- PEP 3123: Provide forward compatibility with Python 3.0, while
8798 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8799 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008800
Georg Brandl3ee81df2008-05-17 18:14:43 +00008801- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8802 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008803
8804- Patch #1733960: Allow T_LONGLONG to accept ints.
8805
8806- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8807
Christian Heimes000a0742008-01-03 22:16:32 +00008808- Added a new API function ``PyImport_ImportModuleNoBlock``.

8811
8812- Fix some leftovers from the conversion from int to Py_ssize_t
8813 (relevant to strings and sequences of more than 2**31 items).
8814
8815- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8816 outside of pystate.c and should not be necessary.
8817
Georg Brandl3ee81df2008-05-17 18:14:43 +00008818- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8819 absolute imports. In earlier versions they might have used relative
8820 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008821
Georg Brandl3ee81df2008-05-17 18:14:43 +00008822- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8823 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008824
Georg Brandl3ee81df2008-05-17 18:14:43 +00008825- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8826 macro so it can be used as an expression.

8831
Georg Brandl3ee81df2008-05-17 18:14:43 +00008832- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8833 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8834 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8835 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008836
Georg Brandl3ee81df2008-05-17 18:14:43 +00008837- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008850- Removed the macfs module. It had been deprecated since Python 2.5.
8851 This lead to the deprecation of macostools.touched() as it relied
8852 solely on macfs and was a no-op under OS X.
