1173 some more recent platforms.
1174
Gregory P. Smitha06ad5b2013-02-01 13:07:27 -08001175- Issue #12268: The io module file object write methods no longer abort early
1176 when a write system calls is interrupted (EINTR).
Gregory P. Smitha998ad02013-02-01 13:02:59 -08001177
Gregory P. Smith0d68ab32012-11-27 10:19:29 -08001178- Fix the leak of a dict in the time module when used in an embedded
1179 interpreter that is repeatedly initialized and shutdown and reinitialized.
1180
Gregory P. Smith99716162012-10-12 13:02:06 -07001181- Issue #12268: File readline, readlines and read or readall methods
1182 no longer lose data when an underlying read system call is interrupted
1183 within an io module object. IOError is no longer raised due to a read
1184 system call returning EINTR from within these methods.
1185
Christian Heimes8112ea22012-09-24 13:17:08 +02001186- Issue #16012: Fix a regression in pyexpat. The parser's UseForeignDTD()
1187 method doesn't require an argument again.
1188
Ned Deily18fae3f2013-01-31 01:24:55 -08001189- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1190 In particular, fix extension module build failures when trying to use
1191 32-bit-only installer Pythons on systems with Xcode 4 (currently
1192 OS X 10.8, 10.7, and optionally 10.6).
1193 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1194 * Since Xcode 4 removes ppc support, extension module builds now
1195 check for ppc compiler support and by default remove ppc and
1196 ppc64 archs when they are not available.
1197 * Extension module builds now revert to using system installed
1198 headers and libs (/usr and /System/Library) if the SDK used
1199 to build the interpreter is not installed or has moved.
1200 * Try to avoid building extension modules with deprecated
1201 and problematic Apple llvm-gcc compiler. If original compiler
1202 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001553- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1554 int.__pow__. These overflow checks were causing int.__pow__ to produce
1555 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001556 compiler optimizing the check away. Also fix similar overflow checks
1557 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1558 bugs caused test failures with recent versions of Clang.

1570 cleared by the garbage collector. This fixes a segfault when an instance
1571 and its type get caught in a reference cycle, and the instance's
1572 deallocator calls one of the methods on the type (e.g. when subclassing
1573 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +02001582 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1583 raw_input() interrupted by CTRL+c.

Florent Xiclunac2279652012-02-12 14:49:03 +01001626- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001627 has left two versions of customize_compiler, the original in
1628 distutils.sysconfig and another copy in distutils.ccompiler, with some
1629 parts of distutils calling one and others using the other.

1631 is the case in 3.x.
1632
Ned Deily0d0ea482012-02-10 12:59:06 +01001633- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1634 Distutils-based packages with C extension modules may fail because
1635 Apple has removed gcc-4.2, the version used to build python.org
1636 64-bit/32-bit Pythons. If the user does not explicitly override
1637 the default C compiler by setting the CC environment variable,
1638 Distutils will now attempt to compile extension modules with clang
1639 if gcc-4.2 is required but not found. Also as a convenience, if
1640 the user does explicitly set CC, substitute its value as the default
1641 compiler in the Distutils LDSHARED configuration variable for OS X.
1642 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1643 SDK, neither of which are available in Xcode 4. This change does not
1644 attempt to override settings to support their use with Xcode 4.)

1754 arguments with the system default encoding just like the write() method
Éric Araujob21f51a2011-10-23 04:37:51 +02001755 does, instead of converting it to a raw buffer. This also fixes handling of

Ned Deily87e82bb2011-06-28 19:52:59 -07001894- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1895 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1896 interpreter process. This could cause failures in non-Distutils subprocesses
1897 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001898 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001899 deployment target only in the environment of each build subprocess. It is
1900 still possible to globally override the default by setting
1901 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1902 greater or equal to the default value, the value with which the interpreter
1903 was built.

1932 updating the check interval, so if the user decreases the check interval,
1933 the ticker doesn't have to wind down to zero from the old starting point
1934 before the new interval takes effect. And if the user increases the
1935 interval, it makes sure the new limit takes effect right away rather have an
1936 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002916- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2917 This prevents user-created self-referencing ordered dictionaries from
2918 becoming permanently uncollectable GC garbage. The downside is that
2919 removing __del__ means that the internal doubly-linked list has to wait for
2920 GC collection rather than freeing memory immediately when the refcnt drops
2921 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003380- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3381 start byte and the continuation byte(s) are now considered invalid, instead
3382 of the number of bytes specified by the start byte.
3383 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3384 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3385 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3395 objects. (1) The comparison could incorrectly return True in some cases
3396 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3397 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00003740- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003741 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3742 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3743 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00003762
3763Core and Builtins
3764-----------------
3765
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003766- Issue #7301: Add environment variable $PYTHONWARNINGS.
3767
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003768- Issue #8329: Don't return the same lists from select.select when no fds are
3769 changed.
3770
Georg Brandlfee0f442010-05-22 21:26:21 +00003771- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003772 on 64-bit machines. The shift count for either left or right shift is
3773 permitted to be up to sys.maxsize.
3774
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003775- Ensure that tokenization of identifiers is not affected by locale.
3776
Georg Brandlfee0f442010-05-22 21:26:21 +00003777- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003778
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003779- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3780
Georg Brandlfee0f442010-05-22 21:26:21 +00003781- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3782 with a non-empty format string. This is an effort to future-proof user
3783 code. If a derived class does not currently implement __format__ but later
3784 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003785 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003786 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003787
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003788- Issue #8268: Old-style classes (not just instances) now support weak

3797 arguments to a function correct.
3798
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003799- Issue #8164: Don't allow lambda functions to have a docstring.
3800
Victor Stinner66644262010-03-10 22:30:19 +00003801- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003802 (SIGINT). If an error occurs while importing the site module, the error is
3803 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003804 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003817- Issue #8310: Allow dis to examine new style classes.
3818
Georg Brandlfee0f442010-05-22 21:26:21 +00003819- Issue #8257: The Decimal construct now accepts a float instance directly,
3820 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003821
3822 >>> Decimal(1.1)
3823 Decimal('1.100000000000000088817841970012523233890533447265625')
3824
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003825- collections.Counter() now supports a subtract() method.
3826
Georg Brandlfee0f442010-05-22 21:26:21 +00003827- The functools module now has a total_ordering() class decorator to simplify
3828 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003829
Georg Brandlfee0f442010-05-22 21:26:21 +00003830- The functools module also adds cmp_to_key() as a tool to transition old-style
3831 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003832
Georg Brandlfee0f442010-05-22 21:26:21 +00003833- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3834 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003835
Georg Brandlfee0f442010-05-22 21:26:21 +00003836- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3837 InvalidOperation instead of returning False. (Comparisons involving a quiet
3838 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3839 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003840
Georg Brandlfee0f442010-05-22 21:26:21 +00003841- Issue #2531: Comparison operations between floats and Decimal instances now
3842 return a result based on the numeric values of the operands; previously they
3843 returned an arbitrary result based on the relative ordering of id(float) and
3844 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003845
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003846- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003847 argument `-` which tells it to read files to compile from stdin. Each line is
3848 read on demand and the named file is compiled immediately. (Original patch by
3849 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003850
Georg Brandlfee0f442010-05-22 21:26:21 +00003851- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003854- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3855 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003856 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003857
Georg Brandlfee0f442010-05-22 21:26:21 +00003858- Comparisons using one of <, <=, >, >= between a complex instance and a
3859 Fractions instance now raise TypeError instead of returning True/False. This
3860 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3861 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003862

3871
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003872- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003873 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3874 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003875
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003876- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3877 deprecated.

3970 the set of integer codes for which it was used differed between native packing
3971 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00004202- Issue #5677: Explicitly forbid write operations on read-only file objects,
4203 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004204 library would return a bogus result; on Solaris, it was possible to crash the
4205 interpreter. Patch by Stefan Krah.

4216 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00004217
Georg Brandlba83f822010-03-14 09:50:54 +00004218- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4219 and add the additional members returned in an OSVERSIONINFOEX structure. The
4220 new members are service_pack_major, service_pack_minor, suite_mask, and
4221 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00004223- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4224 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4225 returning NULL. The macro now returns a statically allocated empty string
4226 instead.

4236 strings,
4237 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4238 numeric strings corresponding to subnormal values,
4239 (3) a memory leak for some values large enough to cause overflow, and
4240 (4) a number of flaws that could lead to incorrectly rounded results.
4241
4242- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
4243 option is not used.

R. David Murray63e4fd72010-02-10 22:42:04 +00004257- Issue #7835: shelve should no longer produce mysterious warnings during
4258 interpreter shutdown.
4259
Georg Brandlba83f822010-03-14 09:50:54 +00004260- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4261 XML processing instructions and comments. These raw characters are allowed
4262 by the XML specification, and are necessary when outputting e.g. PHP code in
4263 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00004271- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004272 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004273 Also, raise ValueError rather than TypeError when an unknown TIPC address
4274 type is specified. Patch by Brian Curtin.
4275
Vinay Sajip28c382f2010-02-04 18:48:53 +00004276- logging: Implemented PEP 391.
4277
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004278- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004279 file position when calling `truncate()`. It would previously change the file
4280 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004281 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4282
Georg Brandlba83f822010-03-14 09:50:54 +00004283- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4284 class used to represent files stored inside an archive. The new
4285 implementation is significantly faster and can be wrapped in a
4286 ``io.BufferedReader`` object for more speedups. It also solves an issue
4287 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4288 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00004289
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004290- Issue #7792: Registering non-classes to ABCs raised an obscure error.

4296 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004297
Georg Brandlba83f822010-03-14 09:50:54 +00004298- Issue #7748: Since unicode values are supported for some metadata options in
4299 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4300 encoded string for them. This ensures that the upload and register commands
4301 send the correct values to PyPI without any error.

4376-----------------
4377
Georg Brandlba83f822010-03-14 09:50:54 +00004378- The ``__complex__()`` method is now looked up on the class of instances to
4379 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004381- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4382 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4383
Mark Dickinson1b34d252010-01-01 17:27:30 +00004384- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004385 DeprecationWarning when passed a float argument where an integer was expected.
4386 These functions and methods now raise TypeError instead. The majority of the
4387 effects of this change are in the extension modules, but some core functions
4388 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4389 and many unicode/str methods.

4413
Georg Brandlba83f822010-03-14 09:50:54 +00004414 These executables now work properly with the arch(1) command: ``arch -ppc
4415 python`` will start a universal binary version of python in PPC mode (unlike
4416 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004572- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4573 decimal string that's guaranteed to round back to x under correct rounding
4574 (with round-half-to-even rounding mode). Previously it gave a string based on
4575 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4576 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4577 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004578
Georg Brandlba83f822010-03-14 09:50:54 +00004579- Issue #7117: On almost all platforms: float-to-string and string-to-float
4580 conversions within Python are now correctly rounded. Places these conversions
4581 occur include: str for floats and complex numbers; the float and complex
4582 constructors; old-style and new-style numeric formatting; serialization and
4583 deserialization of floats and complex numbers using marshal, pickle and json;
4584 parsing of float and imaginary literals in Python code; Decimal-to-float
4585 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004586
Georg Brandlba83f822010-03-14 09:50:54 +00004587 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4588 providing correctly-rounded strtod and dtoa C functions. This code is
4589 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4590 the C compiler. There may be a small number of platforms on which correct
4591 operation of this code cannot be guaranteed, so the code is not used: notably,
4592 this applies to platforms where the C double format is not IEEE 754 binary64,
4593 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4594 and Python's configure script is unable to determine how to change the FPU
4595 precision. On these platforms conversions use the platform strtod and dtoa,
4596 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004597
Georg Brandlba83f822010-03-14 09:50:54 +00004598- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4599 uses the correctly-rounded string <-> float conversions described above (when
4600 available), and so produces correctly rounded results that will display nicely
4601 under the float repr. There are two related small changes: (1) round now
4602 accepts any class with an ``__index__()`` method for its second argument (but
4603 no longer accepts floats for the second argument), and (2) an excessively
4604 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4605 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004752- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4753 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4754 but with at least one decimal point and with a default precision
4755 of 12. Previously, the behavior the same but with a default precision of 6.
4756 This more closely matches ``str()``, and reduces surprises when adding
4757 alignment flags to the empty presentation type. This also affects the new
4758 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00004906- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
4907 file with `str' filename on Windows.
4908
Antoine Pitrouaa687902009-01-01 14:11:22 +00004909- Issue #3680: Reference cycles created through a dict, set or deque iterator

4911
Georg Brandlba83f822010-03-14 09:50:54 +00004912- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
4913 the tp_hash and tp_dict slots are both NULL.

Benjamin Peterson7af65562008-12-29 17:56:58 +00004915- Issue #4764: With io.open, IOError.filename is set when trying to open a

4917
Benjamin Petersonfe231b02008-12-29 17:47:42 +00004918- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
4919 systems.
4920
Georg Brandl6425a2f2008-12-28 11:54:53 +00004921- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004922 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004923
Skip Montanarof205c132008-12-23 03:30:15 +00004924- Added test case to ensure attempts to read from a file opened for writing
4925 fail.
4926
Georg Brandlba83f822010-03-14 09:50:54 +00004927- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4928 elapsed times, not only when some objects are uncollectable/unreachable.
4929 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00004941- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4942 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4943 instances. On a typical machine this saves 3 bytes of memory (on average) per
4944 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004945
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004946- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4947 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4948 instead of throwing a MemoryError.
4949
Georg Brandlba83f822010-03-14 09:50:54 +00004950- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4951 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004952
Benjamin Petersonc078f922008-11-21 22:27:24 +00004953- Issue #4367: Python would segfault during compiling when the unicodedata
4954 module couldn't be imported and \N escapes were present.
4955
Georg Brandlba83f822010-03-14 09:50:54 +00004956- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4957 file objects with closefd=False. The file descriptor is still kept open but
4958 the file object behaves like a closed file. The ``FileIO`` object also got a
4959 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004960
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004961- Issue #4348: Some bytearray methods returned that didn't cause any change to
4962 the bytearray, returned the same bytearray instead of a copy.
4963
Georg Brandlba83f822010-03-14 09:50:54 +00004964- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00004966- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4967
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004968- Issue #4048: The parser module now correctly validates relative imports.
4969
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004970- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4971 exec statement.
4972
Georg Brandlba83f822010-03-14 09:50:54 +00004973- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4974 does not return iterators for the 4th and 5th items.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00004976- Issue #4209: Enabling unicode_literals and the print_function in the same
4977 __future__ import didn't work.
4978
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004979- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004980 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004981
Georg Brandlba83f822010-03-14 09:50:54 +00004982- On windows, ``os.chdir()`` given unicode was not working if
4983 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4984 this code path is really executed because I cannot move to such directory on
4985 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004986
Georg Brandlba83f822010-03-14 09:50:54 +00004987- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4988 element is temporarily replaced with an equivalent frozenset. But the
4989 eventual KeyError would always report the empty ``frozenset()`` as the missing
4990 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004991
Georg Brandlba83f822010-03-14 09:50:54 +00004992- Issue #4509: Various issues surrounding resize of bytearray objects to which
4993 there are buffer exports.

5000
Georg Brandlba83f822010-03-14 09:50:54 +00005001- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00005004- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5005 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005006
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005007- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5008 returned them on 64bit platforms.
5009
Walter Dörwalded960ac2009-05-03 22:36:33 +00005010- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5011 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5012 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5013 of using the replace error handler in PyUnicode_DecodeUTF8().
5014
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005015- Issue #3739: The unicode-internal encoder now reports the number of characters
5016 consumed like any other encoder (instead of the number of bytes).
5017
Georg Brandlba83f822010-03-14 09:50:54 +00005018- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5019 allocator will be automatically disabled when running under Valgrind. This
5020 gives improved memory leak detection when running under Valgrind, while taking
5021 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006266- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6267 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006268 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6269 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006274- Issue #5354: New test support function import_fresh_module() makes it easy to
6275 import both normal and optimised versions of modules. test_heapq and
6276 test_warnings have been adjusted to use it, tests for other modules with both
6277 C and Python implementations in the stdlib can be adjusted to use it over
6278 time.

6287 should cause a test to be skipped are now done using import_module from test
6288 support, which does the conversion.

6390
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006391- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6392 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6393 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6394 ``printf`` function, whereas PyString_FromFormat has an independent
6395 implementation and uses "%zd" on all platforms for size_t values.
6396 This makes a difference on win64, where ``printf`` needs "%Id" to display
6397 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006399- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6403 object; previously an int would be returned for small values. the __long__
6404 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006414 was correctly parsed but parsing of subsequent arguments failed.
6415
Vinay Sajip35e3b032008-09-01 14:33:59 +00006416- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006417 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6418 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6419 when given a tuple of classes as second argument, were looking up
6420 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6421 type object.
6422

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006560What's New in Python 2.6 beta 3?
6561================================
6562
Barry Warsaw07a4a382008-08-21 01:15:08 +00006563*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006564
6565Core and Builtins
6566-----------------
6567
Guido van Rossumf8402962008-08-20 15:01:50 +00006568- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6569 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6570 extensions do not automatically benefit from the class attribute
6571 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6572 to their tp_flags field if they care. This is a backwards
6573 compatibility feature; in 3.0, all types will use the cache by
6574 default.
6575
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006576- Keyword arguments can now follow starred arguments. (``f(a, *args,
6577 keyword=23)`` is now valid syntax.)
6578
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006579- ctypes function pointers that are COM methods have a boolean True
6580 value again.
6581
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006582- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6583 by denying s# to parse objects that have a releasebuffer procedure,
6584 and introducing s*.
6585
Georg Brandl1e13ea92008-08-11 09:07:59 +00006586- Issue #3537: Fix an assertion failure when an empty but presized dict
6587 object was stored in the freelist.
6588
Mark Dickinsonb6467572008-08-04 21:30:09 +00006589- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6590 ValueError consistently across platforms.
6591
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006592- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6593 (64bit Unix, for example), unichr() would truncate its argument and return
6594 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6595
Neal Norwitze7d8be82008-07-31 17:17:14 +00006596- Apply security patches from Apple.
6597
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006598- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6599 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6600
Antoine Pitrou92f82162008-07-25 22:22:08 +00006601- Issue #1819: function calls with several named parameters are now on
6602 average 35% faster (as measured by pybench).
6603
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006604- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6605 the python debugger steps into a class statement: the free variables (local
6606 variables defined in an outer scope) would be deleted from the outer scope.
6607
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006608- Issue #2620: Overflow checking when allocating or reallocating memory
6609 was not always being done properly in some python types and extension
6610 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6611 all been updated to perform better checks and places in the code that
6612 would previously leak memory on the error path when such an allocation
6613 failed have been fixed.
6614
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006615Library
6616-------
6617
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006618- Issue #3612: Added some missing basic types in ctypes.wintypes.
6619
Benjamin Petersone977ad42008-08-20 01:42:01 +00006620- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6621 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6622
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006623- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6624 version reported by these tools does not necessarily follow the python
6625 version numbering scheme, so the module is less strict when parsing it.
6626
Nick Coghlanf70385a2008-08-18 12:42:46 +00006627- Issue #2235: Added Py3k warnings for types which will become unhashable
6628 under the stricter __hash__ inheritance rules in 3.0. Several types
6629 which did not meet the rules for hash invariants and were already
6630 unhashable in 3.0 have now been explicitly flagged as unhashable in
6631 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6632 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6633
Brett Cannon88f801d2008-08-18 00:46:22 +00006634- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6635 imported into the module but exposed as part of the module's API.
6636
Brett Cannon7b96f072008-08-18 00:41:11 +00006637- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6638
Brett Cannon46225e72008-08-18 00:36:52 +00006639- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6640
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006641- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6642
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006643- Issue #3575: Incremental decoder's decode function now takes bytearray
6644 by using 's*' instead of 't#'.
6645
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006646- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006647 fails unicode conversion on 2nd parameter. (windows only)
6648
Georg Brandl222e2082010-08-01 22:27:39 +00006649- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006650 in a redirect.
6651
Brett Cannonabe423e2008-08-16 21:47:07 +00006652- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006653 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006654
Facundo Batistaeb90b782008-08-16 14:44:07 +00006655- Issue #2776: fixed small issue when handling an URL with double slash
6656 after a 302 response in the case of not going through a proxy.
6657
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006658- Issue #2676: in the email package, content-type parsing was hanging on
6659 pathological input because of quadratic or exponential behaviour of a
6660 regular expression.
6661
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006662- Issue #3476: binary buffered reading through the new "io" library is now
6663 thread-safe.
6664
Brett Cannonbf3157b2008-08-14 05:00:03 +00006665- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6666 since mimetools itself is deprecated. Because modules are cached, all
6667 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6668
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006669- Issue #3134: shutil referenced undefined WindowsError symbol.
6670
Robert Schuppenies14646332008-08-10 11:01:53 +00006671- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6672 menu entries were not deleted.
6673
Brett Cannon83e81842008-08-09 23:30:55 +00006674- Copied the implementation of reduce() to _functools.reduce() to have a
6675 version that did not raise a DeprecationWarning under -3.
6676
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006677- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6678 a MemoryError rather than silently stop the iteration.
6679
Guido van Rossum59ce9012008-08-09 14:55:34 +00006680- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6681 to _sre.compile() will now be rejected. This should not affect anybody
6682 since the re.compile() function never generates invalid re-bytecode.
6683
Skip Montanaroa032bf42008-08-08 22:52:51 +00006684- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6685 upon first access it can be automatically initialized from the csv file if
6686 it wasn't initialized during instantiation.
6687
Brett Cannon3aa2a492008-08-06 22:28:09 +00006688- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6689 the reload() built-in has been removed.
6690
Brett Cannon7e30b672008-08-04 21:52:25 +00006691- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006692 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006693 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6694 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6695 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6696 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6697 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006698
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006699- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6700 raised an AttributeError.
6701
Benjamin Peterson01a24322008-07-28 23:35:27 +00006702- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006703 asking for a specific length. This problem only affected files opened
6704 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006705
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006706- Issue #3449: Update decimal module to use most recent specification
6707 (v. 1.68) and tests (v. 2.58) from IBM.
6708
Georg Brandl222e2082010-08-01 22:27:39 +00006709- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006710

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006712 on a closed shelf.
6713
Georg Brandlf9efabb2008-07-23 15:16:45 +00006714- Deprecate the "ast" parser function aliases.
6715
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006716- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6717
6718- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6719 invalid arguments.
6720
6721- Issue #3302: Fix several crashes when calling locale's gettext functions
6722 with None arguments.
6723
6724- Issue #3389: Allow resolving dotted names for handlers in logging
6725 configuration files.
6726
6727- Deprecate the sunaudio module for removal in Python 3.0.
6728
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006729- Issue #3394: zipfile.writestr sets external attributes when passed a
6730 file name rather than a ZipInfo instance, so files are extracted with
6731 mode 0600 rather than 000 under Unix.
6732
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006733- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6734 argument in python 2.5, this broke code that subclassed Popen to include its
6735 own poll method. Fixed my moving _deadstate to an _internal_poll method.
6736
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00006737Build
6738-----

6743-------------
6744
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006745- Issue #2235: the C API function PyObject_HashNotImplemented and its
6746 interaction with the tp_hash slot (added in 2.6b2) are now documented
6747
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006748- Issue #643841: The language reference now provides more detailed
6749 coverage of the lookup process for special methods. The disclaimers
6750 regarding lack of coverage of new-style classes have also been
6751 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006754What's New in Python 2.6 beta 2?
6755================================
6756
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006757*Release date: 17-Jul-2008*
6758
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006759Core and Builtins
6760-----------------
6761
Georg Brandl3e483f62008-07-16 22:57:41 +00006762- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6763 its methods now allow for items objects that can be converted to
6764 an integer using operator.index().
6765
Mark Dickinson64b7e502008-07-16 09:40:03 +00006766- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6767 produced a ValueError instead of giving the correct float.
6768
Eric Smitha5fa5a22008-07-16 00:11:49 +00006769- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6770 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6771
Mark Dickinson7103aa42008-07-15 19:08:33 +00006772- Issue #3008: the float type has a new instance method 'float.hex'
6773 and a new class method 'float.fromhex' to convert floating-point
6774 numbers to and from hexadecimal strings, respectively.
6775
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006776- Issue #2235: __hash__ is once again inherited by default. To allow
6777 collections.Hashable to remain meaningful in the presence of the
6778 default hash implementation (object.__hash__), it is now possible
6779 to explicit block inheritance of hash by setting __hash__=None at
6780 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6781 level.
6782
Nick Coghlanb028f502008-07-13 14:52:36 +00006783- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6784 the parent module cannot be found while performing an absolute import.
6785 This means that an incorrectly defined __package__ attribute will
6786 now only prevent relative imports in that module rather than causing
6787 all imports from that module to fail.
6788
Nick Coghlan14ff9942008-07-08 14:21:42 +00006789- Issue #2517: Allow unicode messages in Exceptions again by correctly
6790 bypassing the instance dictionary when looking up __unicode__ on
6791 new-style classes.
6792
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006793- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6794 set to a custom object whose write() method happens to install
6795 another file in sys.stdout.
6796
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006797- Issue #3088: Corrected a race condition in classes derived from
6798 threading.local: the first member set by a thread could be saved in
6799 another thread's dictionary.
6800
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006801- Issue #3004: Minor change to slice.indices(): the start and stop
6802 arguments are now treated identically, making the behaviour easier
6803 to describe and understand. For example, slice(None, -10,
6804 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6805 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6806 10, -1).
6807
Georg Brandl278fc502008-07-19 12:46:12 +00006808- Issue #3219: Calling a function with repeated keyword arguments,
6809 f(a=2, a=23), would not cause a syntax error. This was a regression
6810 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006811
Georg Brandl278fc502008-07-19 12:46:12 +00006812- Issue #2862: Make int and float freelist management consistent with
6813 other freelists. Changes their CompactFreeList apis into
6814 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006815

6817-------
6818
Thomas Heller57adf222008-08-14 19:10:48 +00006819- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6820 api functions without holding the GIL, which could lead to a fatal
6821 error when they failed.
6822
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006823- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6832 ForkingPickler.register() to resolve conflict with ctypes.
6833
Vinay Sajip51e65192008-07-18 09:01:10 +00006834- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6837 a valid dlerror() message.
6838
Thomas Heller2bad6572008-07-15 17:19:50 +00006839- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6840 incomplete structure was created.

7259 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007260 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007261
7262 This is controlled by the configure argument ``--with-universal-archs``:
7263
7264 - ``--with-universal-archs=all``: install 4-way universal
7265
7266 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7267
7268 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7269
7270 This option should be used in combination with ``--enable-universalsdk=``.
7271

7309 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007310
Christian Heimese74c8f22008-04-19 02:23:57 +00007311- Added kill, terminate and send_signal(sig) to subprocess.Popen.

7314 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007315

Georg Brandl3ee81df2008-05-17 18:14:43 +00007322- Issue #1631171: Re-implement the 'warnings' module in C (the
7323 original Python code has been kept as backup). This will allow for
7324 using the 'warning's machinery in such places as the parser where
7325 use of pure Python code is not possible. Both the ``showarning()``
7326 and ``formatwarning()`` gain an optional 'line' argument which is
7327 not called by default for backwards-compatibility reasons. Setting
7328 ``warnings.showwarning()`` to an implementation that lacks support
7329 for the ``line`` argument will raise a DeprecationWarning.

7353
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007354- The getpass module has been improved on Unix. It now uses /dev/tty
7355 by default and uses stderr instead of stdout. A GetPassWarning is
7356 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007357

Georg Brandl3ee81df2008-05-17 18:14:43 +00007371- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007372 extension modules between 32 and 64 bit platforms. See the distutls

7394 effort to facilitate running multiple instances of the entire
7395 regression test suite in parallel without issue.
7396 test_support.bind_port() has been fixed such that it will always
7397 return a unique port -- which wasn't always the case with the
7398 previous implementation, especially if socket options had been set
7399 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7400 new implementation of bind_port() will actually raise an exception
7401 if it is passed an AF_INET/SOCK_STREAM socket with either the
7402 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7403 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7404 the socket it's been passed. This currently only applies to
7405 Windows. This option prevents any other sockets from binding to the
7406 host/port we've bound to, thus removing the possibility of the
7407 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7408 when a second SOCK_STREAM socket binds and accepts to a host/port
7409 that's already been bound by another socket. The optional preferred
7410 port parameter to bind_port() has been removed. Under no
7411 circumstances should tests be hard coding ports!
7412
7413 test_support.find_unused_port() has also been introduced, which will
7414 pass a temporary socket object to bind_port() in order to obtain an
7415 unused port. The temporary socket object is then closed and
7416 deleted, and the port is returned. This method should only be used
7417 for obtaining an unused port in order to pass to an external program
7418 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7419 a parameter to a server-oriented class that doesn't give you direct
7420 access to the underlying socket used.
7421
7422 Finally, test_support.HOST has been introduced, which should be used
7423 for the host argument of any relevant socket calls (i.e. bind and
7424 connect).

7426 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007427 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007428 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7429 test_asynchat and test_socket_ssl.
7430
Georg Brandl3ee81df2008-05-17 18:14:43 +00007431 It is now possible for multiple instances of the regression test
7432 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00007701- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007702 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007703
Georg Brandlad61bc82008-02-23 15:11:18 +00007704- Issue #2067: file.__exit__() now calls subclasses' close() method.
7705
7706- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007707
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007708- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007709 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007710
Eric Smitha73fbe72008-02-23 03:09:44 +00007711- Added the future_builtins module, which contains hex() and oct().
7712 These are the PEP 3127 version of these functions, designed to be
7713 compatible with the hex() and oct() builtins from Python 3.0. They
7714 differ slightly in their output formats from the existing, unchanged
7715 Python 2.6 builtins. The expected usage of the future_builtins
7716 module is:
7717 from future_builtins import hex, oct
7718
Eric Smith7ef40bf2008-02-20 23:34:22 +00007719- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7720 exponents for exponents with absolute value < 100. Follows C99
7721 standard. This is a change on Windows, which would use 3 digits.
7722 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7723 so that any alterations it does to the resulting string will be
7724 available in stringlib/formatter.h (for float.__format__).
7725
Eric Smith5a3c1352008-02-19 13:21:56 +00007726- Implemented PEP 3101, Advanced String Formatting. This adds a new
7727 builtin format(); a format() method for str and unicode; a
7728 __format__() method to object, str, unicode, int, long, float, and
7729 datetime; the class string.Formatter; and the C API
7730 PyObject_Format().
7731
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732- Fixed several potential crashes, all caused by specially crafted
7733 __del__ methods exploiting objects in temporarily inconsistent
7734 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007735
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007736- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007737 prevent a possible crash: an Abstract Base Class would try to access
7738 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007739
Georg Brandl3ee81df2008-05-17 18:14:43 +00007740- Fixed repr() and str() of complex numbers with infinity or nan as
7741 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007742
Georg Brandl3ee81df2008-05-17 18:14:43 +00007743- Clear all free lists during a gc.collect() of the highest generation
7744 in order to allow pymalloc to free more arenas. Python may give back
7745 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007746
Georg Brandl3ee81df2008-05-17 18:14:43 +00007747- Issue #2045: Fix an infinite recursion triggered when printing a
7748 subclass of collections.defaultdict, if its default_factory is set
7749 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007750
Christian Heimesf75dbef2008-02-08 00:11:31 +00007751- Fixed a minor memory leak in dictobject.c. The content of the free
7752 list was not freed on interpreter shutdown.
7753
Georg Brandl21e99f42010-03-07 15:23:59 +00007754- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007755 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007756
Georg Brandl3ee81df2008-05-17 18:14:43 +00007757- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7758 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007759 to compact the internal free lists of pre-allocted ints and floats.
7760
Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7762 calls. Python expected the return type int but the fork familie
7763 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007764
Georg Brandl3ee81df2008-05-17 18:14:43 +00007765- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7766 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007767
Georg Brandl3ee81df2008-05-17 18:14:43 +00007768- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7769 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007770
Georg Brandl3ee81df2008-05-17 18:14:43 +00007771- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7772 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007773
Georg Brandl3ee81df2008-05-17 18:14:43 +00007774- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7775 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007776
Georg Brandl3ee81df2008-05-17 18:14:43 +00007777- Patch #1473257: generator objects gain a gi_code attribute. This is
7778 the same object as the func_code attribute of the function that
7779 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007780
Georg Brandl3ee81df2008-05-17 18:14:43 +00007781- Issue #1920: "while 0" statements were completely removed by the
7782 compiler, even in the presence of an "else" clause, which is
7783 supposed to be run when the condition is false. Now the compiler
7784 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007785
Guido van Rossumeead05f2008-01-24 18:21:02 +00007786- A few crashers fixed: weakref_in_del.py (issue #1377858);
7787 loosing_dict_ref.py (issue #1303614, test67.py);
7788 borrowed_ref_[34].py (not in tracker).
7789
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007790- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007791 suppressed while an extension is loaded by calling SetErrorMode in
7792 dynload_win.c. The error is still reported properly.
7793
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007795 several extension methods and modules do not work without unicode
7796 support.
7797
Georg Brandl26543b12008-01-21 18:36:51 +00007798- Issue #1882: when compiling code from a string, encoding cookies in the
7799 second line of code were not always recognized correctly.
7800
Georg Brandl14404b62008-01-19 19:27:05 +00007801- Issue #1679: "0x" was taken as a valid integer literal.
7802
Georg Brandl6caad7d2008-01-26 14:19:22 +00007803- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007804 added.
7805
Christian Heimesc94e2b52008-01-14 04:13:37 +00007806- sys.float_info / PyFloat_GetInfo: The floating point information
7807 object was converted from a dict to a specialized structseq object.
7808
Georg Brandl3ee81df2008-05-17 18:14:43 +00007809- Patch #1816: Added sys.flags structseq. It exposes the status of
7810 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007811
Georg Brandl3ee81df2008-05-17 18:14:43 +00007812- Objects/structseq.c: Implemented new structseq representation. The
7813 patch makes structseqs (e.g. the return value of os.stat) more
7814 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007815
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816- Patch #1700288: added a type attribute cache that caches method
7817 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007818
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007819- Bug #1776: __import__() no longer accepts filenames on any platform.

7823
Georg Brandl3ee81df2008-05-17 18:14:43 +00007824- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7825 envvar and sys.dont_write_bytecode attribute. All these can be set
7826 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007827
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Improve some exception messages when Windows fails to load an
7829 extension module. Now we get for example '%1 is not a valid Win32
7830 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007831
Georg Brandl3ee81df2008-05-17 18:14:43 +00007832- Bug #1481296: Fixed long(float('nan')) != 0L.

7835 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007836
Christian Heimes0a8143f2007-12-18 23:22:54 +00007837- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838 and INF. float("nan"), float("inf") and float("-inf") now work on
7839 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007840
Georg Brandl3ee81df2008-05-17 18:14:43 +00007841- Compiler now generates simpler and faster code for dictionary
7842 literals. The oparg for BUILD_MAP now indicates an estimated
7843 dictionary size. There is a new opcode, STORE_MAP, for adding
7844 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007878- Issue #1265: Fix a problem with sys.settrace, if the tracing
7879 function uses a generator expression when at the same time the
7880 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007881
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007882- sets and frozensets now have an isdisjoint() method.

7887
Georg Brandl21e99f42010-03-07 15:23:59 +00007888- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007889 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7890 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007891
Georg Brandl3ee81df2008-05-17 18:14:43 +00007892- Issue #1686386: Tuple's tp_repr did not take into account the
7893 possibility of having a self-referential tuple, which is possible
7894 from C code. Nor did object's tp_str consider that a type's tp_str
7895 could do something that could lead to an inifinite recursion.
7896 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007899- Issue #1164: It was possible to trigger deadlock when using the
7900 'print' statement to write to a file since the GIL was not released
7901 as needed. Now PyObject_Print() does the right thing along with
7902 various tp_print implementations of the built-in types and those in
7903 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007904
Georg Brandl3ee81df2008-05-17 18:14:43 +00007905- Issue #1147: Exceptions were directly allowing string exceptions in
7906 their throw() method even though string exceptions no longer
7907 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007908
Georg Brandl3ee81df2008-05-17 18:14:43 +00007909- Issue #1096: Prevent a segfault from getting the repr of a very
7910 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007911
Brett Cannon1e534b52007-09-07 04:18:30 +00007912- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007913 PyObject_Call() never calling back out to Python code to trigger
7914 recursion depth updates/checks. Required the creation of a static
7915 RuntimeError instance in case normalizing an exception put the
7916 recursion check value past its limit. Fixes crashers
7917 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007918
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919- Patch #1031213: Decode source line in SyntaxErrors back to its
7920 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00007922- Patch #1673759: add a missing overflow check when formatting floats
7923 with %G.
7924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Prevent expandtabs() on string and unicode objects from causing a
7926 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007927
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00007929
Georg Brandl3ee81df2008-05-17 18:14:43 +00007930- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00007931
Neal Norwitz0ac60192007-05-27 04:08:54 +00007932- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007933 __*__ attributes. (Some already existed, e.g., __doc__ and
7934 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007935
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007936- Add -3 option to the interpreter to warn about features that are
7937 deprecated and will be changed/removed in Python 3.0.
7938
Georg Brandl2134e752007-05-21 20:34:16 +00007939- Patch #1686487: you can now pass any mapping after '**' in function
7940 calls.
7941
Collin Winter62903052007-05-18 23:11:24 +00007942- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943 "except E as target:". This is to provide forwards compatibility
7944 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007945
Brett Cannon229cee22007-05-05 01:34:02 +00007946- Deprecate BaseException.message as per PEP 352.
7947
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007949 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007950
Vinay Sajip8549ce32007-05-06 17:53:37 +00007951- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007952 setting a plain string, ie don't expand to single letter identifiers.
7953
Raymond Hettinger13936692007-04-11 18:40:58 +00007954- Request #1191699: Slices can now be pickled.
7955
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007956- Request #1193128: str.translate() now allows a None argument for
7957 translations that only remove characters without re-mapping the
7958 remaining characters.
7959
Georg Brandl5cb76c12007-03-21 09:00:39 +00007960- Patch #1682205: a TypeError while unpacking an iterable is no longer
7961 masked by a generic one with the message "unpack non-sequence".
7962
Neal Norwitzaa754b72007-03-21 06:39:48 +00007963- Remove unused file Python/fmod.c.
7964
Guido van Rossum143b5642007-03-23 04:58:42 +00007965- Bug #1683368: The object.__init__() and object.__new__() methods are
7966 now stricter in rejecting excess arguments. The only time when
7967 either allows excess arguments is when it is not overridden and the
7968 other one is. For backwards compatibility, when both are
7969 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007970 warning later). Also, type.__init__() insists on the same signature
7971 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007972
Georg Brandl3ee81df2008-05-17 18:14:43 +00007973- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7974 object to complex using its __complex__() method before falling back
7975 to the __float__() method. Therefore, the functions in the cmath
7976 module now can operate on objects that define a __complex__()
7977 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Patch #1623563: allow __class__ assignment for classes with
7980 __slots__. The old and the new class are still required to have the
7981 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007982
Georg Brandl3ee81df2008-05-17 18:14:43 +00007983- Patch #1642547: Fix an error/crash when encountering syntax errors
7984 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007986- Patch #1462488: Python no longer segfaults when
7987 ``object.__reduce_ex__()`` is called with an object that is faking
7988 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Patch #1680015: Don't modify __slots__ tuple if it contains an
7991 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00007992
Georg Brandl5240d742007-03-13 20:46:32 +00007993- Patch #1444529: the builtin compile() now accepts keyword arguments.
7994
Georg Brandl7b9c5552007-03-12 14:30:05 +00007995- Bug #1678647: write a newline after printing an exception in any
7996 case, even when converting the value to a string failed.
7997
Georg Brandl871f1bc2007-03-12 13:17:36 +00007998- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007999 its argument, if it exists. If not, it will work like before. This
8000 allows customizing the output of dir() in the presence of a
8001 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008002
Collin Winter276887b2007-03-12 16:11:39 +00008003- Patch #922167: Python no longer segfaults when faced with infinitely
8004 self-recursive reload() calls (as reported by bug #742342).
8005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- Patch #1675981: remove unreachable code from ``type.__new__()``
8007 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00008008
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009- Patch #1491866: change the complex() constructor to allow
8010 parthensized forms. This means complex(repr(x)) now works instead of
8011 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008012
Georg Brandlaa2321b2007-03-07 00:40:28 +00008013- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014 makes the filenames the warning module prints much more sensible
8015 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008016
Georg Brandl49aafc92007-03-07 00:34:46 +00008017- Variant of patch #697613: don't exit the interpreter on a SystemExit
8018 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008019 variable is given, but break into the interactive interpreter just
8020 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00008021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Bug #1674503: close the file opened by execfile() in an error
8026 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008027
Georg Brandl0fca97a2007-03-05 22:28:08 +00008028- Patch #1674228: when assigning a slice (old-style), check for the
8029 sq_ass_slice instead of the sq_slice slot.
8030
Georg Brandl3ee81df2008-05-17 18:14:43 +00008031- When printing an unraisable error, don't print exceptions. before
8032 the name. This duplicates the behavior whening normally printing
8033 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008041- Bug #1377858: Fix the segfaulting of the interpreter when an object
8042 created a weakref on itself during a __del__ call for new-style
8043 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008044
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008045- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
8046 frame's thread state.
8047

Georg Brandl2c1375c2006-10-12 11:27:59 +00008083- Bug #1545497: when given an explicit base, int() did ignore NULs
8084 embedded in the string to convert.
8085
Georg Brandl846f73a2006-10-08 07:11:54 +00008086- Bug #1569998: break inside a try statement (outside a loop) is now
8087 recognized and rejected.
8088

8090
Armin Rigo7ccbca92006-10-04 12:17:45 +00008091- A number of places, including integer negation and absolute value,
8092 were fixed to not rely on undefined behaviour of the C compiler
8093 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00008094

8096 number of arguments, as was the case in Python 2.4.
8097
Georg Brandl5d59c092006-09-30 08:43:30 +00008098- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099 keyword arguments any more (previously they accepted them, but
8100 didn't use them).
Georg Brandl5d59c092006-09-30 08:43:30 +00008101
Georg Brandl3ee81df2008-05-17 18:14:43 +00008102- Fix a bug in the parser's future statement handling that led to
8103 "with" not being recognized as a keyword after, e.g., this
8104 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00008105

8113 method. This allows calling unicode() on exceptions classes
8114 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00008115
Georg Brandl4e933132006-09-06 20:05:58 +00008116- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8131 head is the original string if sep was not found.
8132
Neal Norwitzdac090d2006-09-05 03:53:08 +00008133- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008134 generator expressions (x for x, in ... ) works again. Fixing this
8135 problem required changing the .pyc magic number. This means that
8136 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00008137

8642 Python would crash instead of raising an error.

8661 -- the failure just occurred later, with a more cumbersome
8662 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00008873- ctypes callback functions only support 'fundamental' data types as

Georg Brandl3ee81df2008-05-17 18:14:43 +00008907- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't

8935 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008936
Georg Brandl3ee81df2008-05-17 18:14:43 +00008937- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8938 with RFC 3207 and forgets any knowledge obtained from the server not
8939 obtained from the TLS negotiation itself. Patch contributed by Bill
8940 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008941
Georg Brandl3ee81df2008-05-17 18:14:43 +00008942- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008943 that the SMTP.starttls() caller no longer needs to call ehlo()
8944 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008945 does not claim to support starttls. Adds the
8946 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8947 Fenner.

8985
Georg Brandl3ee81df2008-05-17 18:14:43 +00008986- Patch #1663329: added ``os.closerange()`` function to quickly close

9027 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9028 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009045 time so that opening a database previously created with the DB_DUP
9046 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9047 opens. Specifically: dictionary assignment to a DB object will
9048 replace all values for a given key when the database allows
9049 duplicate values. DB users should use DB.put(k, v) when they want
9050 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009051

9057 characters with ASCII value less than 32. Also, it correctly quotes
9058 dots only if they occur on a single line, as opposed to the previous
9059 behavior of quoting dots if they are the second character of any
9060 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009061

9392-----
9393
Georg Brandl3ee81df2008-05-17 18:14:43 +00009394- Unified naming convention for free lists and their limits. All free
9395 lists in Object/ are named ``free_list``, the counter ``numfree``
9396 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9397 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009398
Georg Brandl3ee81df2008-05-17 18:14:43 +00009399- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9400 to ``PyTuple_SetItem``, it can be used to populate a brand new
9401 frozenset; but it does not steal a reference to the added item.

9406 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9407 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009408
9409- Patch #1720595: add T_BOOL to the range of structmember types.
9410
9411- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9412 ``PyFloat_GetInfo()`` to the float API.
9413
Georg Brandl3ee81df2008-05-17 18:14:43 +00009414- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9415 of w# format code incorrectly truncated the length to an int, even
9416 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9417 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009418
Georg Brandl3ee81df2008-05-17 18:14:43 +00009419- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9420 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009422- PEP 3123: Provide forward compatibility with Python 3.0, while
9423 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9424 and PyVarObject_HEAD_INIT.

9427 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009428
9429- Patch #1733960: Allow T_LONGLONG to accept ints.

9437- Fix some leftovers from the conversion from int to Py_ssize_t
9438 (relevant to strings and sequences of more than 2**31 items).
9439
9440- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9441 outside of pystate.c and should not be necessary.
9442
Georg Brandl3ee81df2008-05-17 18:14:43 +00009443- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9444 absolute imports. In earlier versions they might have used relative
9445 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009446
Georg Brandl3ee81df2008-05-17 18:14:43 +00009447- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9448 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009449
Georg Brandl3ee81df2008-05-17 18:14:43 +00009450- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009457- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9458 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9459 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9460 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009461

Georg Brandl3ee81df2008-05-17 18:14:43 +00009475- Removed the macfs module. It had been deprecated since Python 2.5.
9476 This lead to the deprecation of macostools.touched() as it relied
9477 solely on macfs and was a no-op under OS X.
